-   A module that plans to do a blocking system call (or something else

-    ...preparations here...
-    Py_BEGIN_ALLOW_THREADS
-    ...blocking system call here...
-    Py_END_ALLOW_THREADS
-    ...interpret result here...
-
-   The Py_BEGIN_ALLOW_THREADS/Py_END_ALLOW_THREADS pair expands to a
-   {}-surrounded block.
-   To leave the block in the middle (e.g., with return), you must insert
-   a line containing Py_BLOCK_THREADS before the return, e.g.
-
-    if (...premature_exit...) {
-        Py_BLOCK_THREADS
-        PyErr_SetFromErrno(PyExc_IOError);

-        PyErr_SetFromErrno(PyExc_IOError);
-        return NULL;
-    }
-    Py_UNBLOCK_THREADS
-
-   For convenience, that the value of 'errno' is restored across
-   Py_END_ALLOW_THREADS and Py_BLOCK_THREADS.
-
-   WARNING: NEVER NEST CALLS TO Py_BEGIN_ALLOW_THREADS AND
-   Py_END_ALLOW_THREADS!!!
-
-   The function PyEval_InitThreads() should be called only from

-   CObjects are marked Pending Deprecation as of Python 2.7.
-   The full schedule for 2.x is as follows:
-     - CObjects are marked Pending Deprecation in Python 2.7.
-     - CObjects will be marked Deprecated in Python 2.8
-       (if there is one).
-     - CObjects will be removed in Python 2.9 (if there is one).
-
-   Additionally, for the Python 3.x series:
-     - CObjects were marked Deprecated in Python 3.1.
-     - CObjects will be removed in Python 3.2.
-
-   You should switch all use of CObjects to capsules.  Capsules
-   have a safer and more consistent API.  For more information,
-   see Include/pycapsule.h, or read the "Capsules" topic in
-   the "Python/C API Reference Manual".
-
-   Python 2.7 no longer uses CObjects itself; all objects which
-   were formerly CObjects are now capsules.  Note that this change
-   does not by itself break binary compatibility with extensions
-   built for previous versions of Python--PyCObject_AsVoidPtr()
-   has been changed to also understand capsules.

-   They provide a way for an extension module to export a C interface

-
-   Each interface exports both functions and macros.  Extension modules should

-   macros you must recompile your extensions with each Python release.
-
-   Never mix calls to PyMem_ with calls to the platform malloc/realloc/
-   calloc/free.  For example, on Windows different DLLs may end up using
-   different heaps, and if you use PyMem_Malloc you'll get the memory from the
-   heap used by the Python DLL; it could be a disaster if you free()'ed that
-   directly in your own extension.  Using PyMem_Free instead ensures Python
-   can return the memory to the proper heap.  As another example, in
-   PYMALLOC_DEBUG mode, Python wraps all calls to all PyMem_ and PyObject_
-   memory functions in special debugging wrappers that add additional
-   debugging info to dynamic memory blocks.  The system routines have no idea
-   what to do with that stuff, and the Python wrappers have no idea what to do

+     means the cleanup code has itself gone into an infinite loop, or the
+     RuntimeError has been mistakingly ignored. When this protection is
+     triggered, the interpreter aborts with a Fatal Error.
+

+   recursion level drops below "current recursion limit - 50". This heuristic
+   is meant to ensure that the normal anti-recursion protection doesn't get

+

+/* This file defines dynamic annotations for use with dynamic analysis
+   tool such as valgrind, PIN, etc.
+
+   Dynamic annotation is a source code annotation that affects
+   the generated code (that is, the annotation is not a comment).
+   Each such annotation is attached to a particular
+   instruction and/or to a particular object (address) in the program.
+
+   The annotations that should be used by users are macros in all upper-case
+   (e.g., _Py_ANNOTATE_NEW_MEMORY).
+
+   Actual implementation of these macros may differ depending on the
+   dynamic analysis tool being used.
+
+   See http://code.google.com/p/data-race-test/  for more information.
+
+   This file supports the following dynamic analysis tools:
+   - None (DYNAMIC_ANNOTATIONS_ENABLED is not defined or zero).
+      Macros are defined empty.
+   - ThreadSanitizer, Helgrind, DRD (DYNAMIC_ANNOTATIONS_ENABLED is 1).
+      Macros are defined as calls to non-inlinable empty functions
+      that are intercepted by Valgrind. */

+     Annotations useful when implementing condition variables such as CondVar,
+     using conditional critical sections (Await/LockWhen) and when constructing
+     user-defined synchronization mechanisms.
+
+     The annotations _Py_ANNOTATE_HAPPENS_BEFORE() and
+     _Py_ANNOTATE_HAPPENS_AFTER() can be used to define happens-before arcs in
+     user-defined synchronization mechanisms: the race detector will infer an
+     arc from the former to the latter when they share the same argument
+     pointer.
+
+     Example 1 (reference counting):
+
+     void Unref() {
+       _Py_ANNOTATE_HAPPENS_BEFORE(&refcount_);
+       if (AtomicDecrementByOne(&refcount_) == 0) {
+         _Py_ANNOTATE_HAPPENS_AFTER(&refcount_);
+         delete this;
+       }
+     }
+
+     Example 2 (message queue):
+
+     void MyQueue::Put(Type *e) {
+       MutexLock lock(&mu_);
+       _Py_ANNOTATE_HAPPENS_BEFORE(e);
+       PutElementIntoMyQueue(e);
+     }
+
+     Type *MyQueue::Get() {
+       MutexLock lock(&mu_);
+       Type *e = GetElementFromMyQueue();
+       _Py_ANNOTATE_HAPPENS_AFTER(e);
+       return e;
+     }
+
+     Note: when possible, please use the existing reference counting and message
+     queue implementations instead of inventing new ones. */

-# | The logfile format is as follows. Each line consists of:
-# |
-# | host rfc931 authuser [DD/Mon/YYYY:hh:mm:ss] "request" ddd bbbb
-# |
-# |        host: Either the DNS name or the IP number of the remote client
-# |        rfc931: Any information returned by identd for this person,
-# |                - otherwise.
-# |        authuser: If user sent a userid for authentication, the user name,
-# |                  - otherwise.
-# |        DD: Day
-# |        Mon: Month (calendar name)
-# |        YYYY: Year
-# |        hh: hour (24-hour format, the machine's timezone)
-# |        mm: minutes
-# |        ss: seconds
-# |        request: The first line of the HTTP request as sent by the client.
-# |        ddd: the status code returned by the server, - if not available.
-# |        bbbb: the total number of bytes sent,
-# |              *not including the HTTP/1.0 header*, - if not available
-# |
-# | You can determine the name of the file accessed through request.

-
-    The following explanation of HTTP serves to guide you through the
-    code as well as to expose any misunderstandings I may have about
-    HTTP (so you don't need to read the code to figure out I'm wrong
-    :-).
-
-    HTTP (HyperText Transfer Protocol) is an extensible protocol on
-    top of a reliable stream transport (e.g. TCP/IP).  The protocol
-    recognizes three parts to a request:
-
-    1. One line identifying the request type and path
-    2. An optional set of RFC-822-style headers
-    3. An optional data part
-
-    The headers and data are separated by a blank line.
-
-    The first line of the request has the form
-
-    <command> <path> <version>
-
-    where <command> is a (case-sensitive) keyword such as GET or POST,
-    <path> is a string containing path information for the request,
-    and <version> should be the string "HTTP/1.0" or "HTTP/1.1".
-    <path> is encoded using the URL encoding scheme (using %xx to signify
-    the ASCII character with hex code xx).
-
-    The specification specifies that lines are separated by CRLF but
-    for compatibility with the widest range of clients recommends
-    servers also handle LF.  Similarly, whitespace in the request line
-    is treated sensibly (allowing multiple spaces between components
-    and allowing trailing whitespace).
-
-    Similarly, for output, lines ought to be separated by CRLF pairs
-    but most clients grok LF characters just fine.
-
-    If the first line of the request has the form
-
-    <command> <path>
-
-    (i.e. <version> is left out) then this is assumed to be an HTTP
-    0.9 request; this form has no optional headers and data part and
-    the reply consists of just the data.
-
-    The reply form of the HTTP 1.x protocol again has three parts:
-
-    1. One line giving the response code
-    2. An optional set of RFC-822-style headers
-    3. The data
-
-    Again, the headers and data are separated by a blank line.
-
-    The response code line has the form
-
-    <version> <responsecode> <responsestring>
-
-    where <version> is the protocol version ("HTTP/1.0" or "HTTP/1.1"),
-    <responsecode> is a 3-digit response code indicating success or
-    failure of the request, and <responsestring> is an optional
-    human-readable string explaining what the response code means.
-
-    This server parses the request and the headers, and then calls a
-    function specific to the request type (<command>).  Specifically,
-    a request SPAM will be handled by a method do_SPAM().  If no
-    such method exists the server sends an error response to the
-    client.  If it exists, it is called with no arguments:
-
-    do_SPAM()
-
-    Note that the request name is case sensitive (i.e. SPAM and spam
-    are different requests).
-
-    The various request details are stored in instance variables:
-
-    - client_address is the client IP address in the form (host,
-    port);
-
-    - command, path and version are the broken-down request line;
-
-    - headers is an instance of mimetools.Message (or a derived
-    class) containing the header information;
-
-    - rfile is a file object open for reading positioned at the
-    start of the optional input data part;
-
-    - wfile is a file object open for writing.
-
-    IT IS IMPORTANT TO ADHERE TO THE PROTOCOL FOR WRITING!
-
-    The first thing to be written must be the response line.  Then
-    follow 0 or more header lines, then a blank line, and then the
-    actual data (if any).  The meaning of the header lines depends on
-    the command executed by the server; in most cases, when data is
-    returned, there should be at least one header line of the form
-
-    Content-type: <type>/<subtype>
-
-    where <type> and <subtype> should be registered MIME types,
-    e.g. "text/html" or "text/plain".

-"""Bastionification utility.
-
-A bastion (for another object -- the 'original') is an object that has
-the same methods as the original but does not give access to its
-instance variables.  Bastions have a number of uses, but the most
-obvious one is to provide code executing in restricted mode with a
-safe interface to an object implemented in unrestricted mode.
-
-The bastionification routine has an optional second argument which is
-a filter function.  Only those methods for which the filter method
-(called with the method name as argument) returns true are accessible.
-The default filter method returns true unless the method name begins
-with an underscore.
-
-There are a number of possible implementations of bastions.  We use a
-'lazy' approach where the bastion's __getattr__() discipline does all
-the work for a particular method the first time it is used.  This is
-usually fastest, especially if the user doesn't call all available
-methods.  The retrieved methods are stored as instance variables of
-the bastion, so the overhead is only occurred on the first use of each
-method.
-
-Detail: the bastion class has a __repr__() discipline which includes
-the repr() of the original object.  This is precomputed when the
-bastion is created.

-"""CGI-savvy HTTP Server.
-
-This module builds on SimpleHTTPServer by implementing GET and POST
-requests to cgi-bin scripts.
-
-If the os.fork() function is not present (e.g. on Windows),
-os.popen2() is used as a fallback, with slightly altered semantics; if
-that function is not present either (e.g. on Macintosh), only Python
-scripts are supported, and they are executed by the current process.
-
-In all cases, the implementation is intentionally naive -- all
-requests are executed sychronously.
-
-SECURITY WARNING: DON'T USE THIS CODE UNLESS YOU ARE INSIDE A FIREWALL
--- it may execute arbitrary Python code or external programs.
-
-Note that status code 200 is sent prior to execution of a CGI script, so
-scripts cannot send other status codes such as 302 (redirect).

-"""Configuration file parser.
-
-A setup file consists of sections, lead by a "[section]" header,
-and followed by "name: value" entries, with continuations and such in
-the style of RFC 822.
-
-The option values can contain format strings which refer to other values in
-the same section, or values in a special [DEFAULT] section.
-
-For example:
-
-    something: %(dir)s/whatever
-
-would resolve the "%(dir)s" to the value of dir.  All reference
-expansions are done late, on demand.
-
-Intrinsic defaults can be specified by passing them into the
-ConfigParser constructor as a dictionary.

-class:

-ConfigParser -- responsible for parsing a list of
-                configuration files, and managing the parsed database.
-
-    methods:
-
-    __init__(defaults=None)
-        create the parser and specify a dictionary of intrinsic defaults.  The
-        keys must be strings, the values must be appropriate for %()s string
-        interpolation.  Note that `__name__' is always an intrinsic default;
-        its value is the section's name.
-
-    sections()
-        return all the configuration section names, sans DEFAULT
-
-    has_section(section)

-        read and parse the list of named configuration files, given by
-        name.  A single filename is also allowed.  Non-existing files
-        are ignored.  Return list of successfully read files.
-
-    readfp(fp, filename=None)
-        read and parse one configuration file, given as a file object.
-        The filename defaults to fp.name; it is only used in error
-        messages (if fp has no `name' attribute, the string `<???>' is used).
-
-    get(section, option, raw=False, vars=None)
-        return a string value for the named option.  All % interpolations are
-        expanded in the return values, based on the defaults passed into the
-        constructor and the DEFAULT section.  Additional substitutions may be
-        provided using the `vars' argument, which must be a dictionary whose
-        contents override any pre-existing defaults.
-

-        like get(), but convert value to an integer
-
-    getfloat(section, options)

-#
-#  Cookie.py is a Python module for the handling of HTTP
-#  cookies as a Python dictionary.  See RFC 2109 for more
-#  information on cookies.
-#
-#  The original idea to treat Cookies as a dictionary came from
-#  Dave Mitchell (davem@magnet.com) in 1995, when he released the
-#  first version of nscookie.py.
-#
-####
-
-r"""
-Here's a sample session to show how to use this module.
-At the moment, this is the only documentation.
-
-The Basics
-----------
-
-Importing is easy..
-
-   >>> import Cookie
-
-Most of the time you start by creating a cookie.  Cookies come in
-three flavors, each with slightly different encoding semantics, but
-more on that later.
-
-   >>> C = Cookie.SimpleCookie()
-   >>> C = Cookie.SerialCookie()
-   >>> C = Cookie.SmartCookie()
-
-[Note: Long-time users of Cookie.py will remember using
-Cookie.Cookie() to create an Cookie object.  Although deprecated, it
-is still supported by the code.  See the Backward Compatibility notes
-for more information.]
-
-Once you've created your Cookie, you can add values just as if it were
-a dictionary.
-
-   >>> C = Cookie.SmartCookie()
-   >>> C["fig"] = "newton"
-   >>> C["sugar"] = "wafer"
-   >>> C.output()
-   'Set-Cookie: fig=newton\r\nSet-Cookie: sugar=wafer'
-
-Notice that the printable representation of a Cookie is the
-appropriate format for a Set-Cookie: header.  This is the
-default behavior.  You can change the header and printed
-attributes by using the .output() function
-
-   >>> C = Cookie.SmartCookie()
-   >>> C["rocky"] = "road"
-   >>> C["rocky"]["path"] = "/cookie"
-   >>> print C.output(header="Cookie:")
-   Cookie: rocky=road; Path=/cookie
-   >>> print C.output(attrs=[], header="Cookie:")
-   Cookie: rocky=road
-
-The load() method of a Cookie extracts cookies from a string.  In a
-CGI script, you would use this method to extract the cookies from the
-HTTP_COOKIE environment variable.
-
-   >>> C = Cookie.SmartCookie()
-   >>> C.load("chips=ahoy; vienna=finger")
-   >>> C.output()
-   'Set-Cookie: chips=ahoy\r\nSet-Cookie: vienna=finger'
-
-The load() method is darn-tootin smart about identifying cookies
-within a string.  Escaped quotation marks, nested semicolons, and other
-such trickeries do not confuse it.
-
-   >>> C = Cookie.SmartCookie()
-   >>> C.load('keebler="E=everybody; L=\\"Loves\\"; fudge=\\012;";')
-   >>> print C
-   Set-Cookie: keebler="E=everybody; L=\"Loves\"; fudge=\012;"
-
-Each element of the Cookie also supports all of the RFC 2109
-Cookie attributes.  Here's an example which sets the Path
-attribute.
-
-   >>> C = Cookie.SmartCookie()
-   >>> C["oreo"] = "doublestuff"
-   >>> C["oreo"]["path"] = "/"
-   >>> print C
-   Set-Cookie: oreo=doublestuff; Path=/
-
-Each dictionary element has a 'value' attribute, which gives you
-back the value associated with the key.
-
-   >>> C = Cookie.SmartCookie()
-   >>> C["twix"] = "none for you"
-   >>> C["twix"].value
-   'none for you'
-
-
-A Bit More Advanced
--------------------
-
-As mentioned before, there are three different flavors of Cookie
-objects, each with different encoding/decoding semantics.  This
-section briefly discusses the differences.
-
-SimpleCookie
-
-The SimpleCookie expects that all values should be standard strings.
-Just to be sure, SimpleCookie invokes the str() builtin to convert
-the value to a string, when the values are set dictionary-style.
-
-   >>> C = Cookie.SimpleCookie()
-   >>> C["number"] = 7
-   >>> C["string"] = "seven"
-   >>> C["number"].value
-   '7'
-   >>> C["string"].value
-   'seven'
-   >>> C.output()
-   'Set-Cookie: number=7\r\nSet-Cookie: string=seven'
-
-
-SerialCookie
-
-The SerialCookie expects that all values should be serialized using
-cPickle (or pickle, if cPickle isn't available).  As a result of
-serializing, SerialCookie can save almost any Python object to a
-value, and recover the exact same object when the cookie has been
-returned.  (SerialCookie can yield some strange-looking cookie
-values, however.)
-
-   >>> C = Cookie.SerialCookie()
-   >>> C["number"] = 7
-   >>> C["string"] = "seven"
-   >>> C["number"].value
-   7
-   >>> C["string"].value
-   'seven'
-   >>> C.output()
-   'Set-Cookie: number="I7\\012."\r\nSet-Cookie: string="S\'seven\'\\012p1\\012."'
-
-Be warned, however, if SerialCookie cannot de-serialize a value (because
-it isn't a valid pickle'd object), IT WILL RAISE AN EXCEPTION.
-
-
-SmartCookie
-
-The SmartCookie combines aspects of each of the other two flavors.
-When setting a value in a dictionary-fashion, the SmartCookie will
-serialize (ala cPickle) the value *if and only if* it isn't a
-Python string.  String objects are *not* serialized.  Similarly,
-when the load() method parses out values, it attempts to de-serialize
-the value.  If it fails, then it fallsback to treating the value
-as a string.
-
-   >>> C = Cookie.SmartCookie()
-   >>> C["number"] = 7
-   >>> C["string"] = "seven"
-   >>> C["number"].value
-   7
-   >>> C["string"].value
-   'seven'
-   >>> C.output()
-   'Set-Cookie: number="I7\\012."\r\nSet-Cookie: string=seven'
-
-
-Backwards Compatibility
------------------------
-
-In order to keep compatibilty with earlier versions of Cookie.py,
-it is still possible to use Cookie.Cookie() to create a Cookie.  In
-fact, this simply returns a SmartCookie.
-
-   >>> C = Cookie.Cookie()
-   >>> print C.__class__.__name__
-   SmartCookie

-A. HISTORY OF THE SOFTWARE
-==========================
-
-Python was created in the early 1990s by Guido van Rossum at Stichting
-Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
-as a successor of a language called ABC.  Guido remains Python's
-principal author, although it includes many contributions from others.
-
-In 1995, Guido continued his work on Python at the Corporation for
-National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
-in Reston, Virginia where he released several versions of the
-software.
-
-In May 2000, Guido and the Python core development team moved to

-Footnotes:
-
-(1) GPL-compatible doesn't mean that we're distributing Python under
-    the GPL.  All Python licenses, unlike the GPL, let you distribute
-    a modified version without making your changes open source.  The
-    GPL-compatible licenses make it possible to combine Python with
-    other software that is released under the GPL; the others don't.
-
-(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
-    because its license has a choice of law clause.  According to
-    CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
-    is "not incompatible" with the GPL.
-
-Thanks to the many outside volunteers who have worked under Guido's
-direction to make these releases possible.

-    Methods:
-
-    __init__()
-    addheader()
-    flushheaders()
-    startbody()
-    startmultipartbody()
-    nextpart()
-    lastpart()
-
-    A MIME writer is much more primitive than a MIME parser.  It
-    doesn't seek around on the output file, and it doesn't use large
-    amounts of buffer space, so you have to write the parts in the
-    order they should occur on the output file.  It does buffer the
-    headers you add, allowing you to rearrange their order.
-
-    General usage is:
-
-    f = <open the output file>
-    w = MimeWriter(f)
-    ...call w.addheader(key, value) 0 or more times...
-
-    followed by either:
-
-    f = w.startbody(content_type)
-    ...call f.write(data) for body data...
-
-    or:
-
-    w.startmultipartbody(subtype)
-    for each part:
-        subwriter = w.nextpart()
-        ...use the subwriter's methods to create the subpart...
-    w.lastpart()
-
-    The subwriter is another MimeWriter instance, and should be
-    treated in the same way as the toplevel MimeWriter.  This way,
-    writing recursive body parts is easy.
-
-    Warning: don't forget to call lastpart()!
-
-    XXX There should be more state so calls made in the wrong order
-    are detected.
-
-    Some special cases:
-
-    - startbody() just returns the file passed to the constructor;
-      but don't use this knowledge, as it may be changed.
-
-    - startmultipartbody() actually returns a file as well;
-      this can be used to write the initial 'if you can read this your
-      mailer is not MIME-aware' message.
-
-    - If you call flushheaders(), the headers accumulated so far are
-      written out (and forgotten); this is useful if you don't need a
-      body part at all, e.g. for a subpart of type message/rfc822
-      that's (mis)used to store some header-like information.
-
-    - Passing a keyword argument 'prefix=<flag>' to addheader(),
-      start*body() affects where the header is inserted; 0 means
-      append at the end, 1 means insert at the start; default is
-      append for addheader(), but insert for start*body(), which use
-      it to determine where the Content-Type header goes.

-r"""Simple XML-RPC Server.
-
-This module can be used to create simple XML-RPC servers
-by creating a server and either installing functions, a
-class instance, or by extending the SimpleXMLRPCServer
-class.
-
-It can also be used to handle XML-RPC requests in a CGI
-environment using CGIXMLRPCRequestHandler.
-
-A list of possible usage patterns follows:
-
-1. Install functions:
-
-server = SimpleXMLRPCServer(("localhost", 8000))
-server.register_function(pow)
-server.register_function(lambda x,y: x+y, 'add')
-server.serve_forever()
-
-2. Install an instance:
-
-class MyFuncs:
-    def __init__(self):
-        # make all of the string functions available through
-        # string.func_name
-        import string
-        self.string = string
-    def _listMethods(self):
-        # implement this method so that system.listMethods
-        # knows to advertise the strings methods
-        return list_public_methods(self) + \
-                ['string.' + method for method in list_public_methods(self.string)]
-    def pow(self, x, y): return pow(x, y)
-    def add(self, x, y) : return x + y
-
-server = SimpleXMLRPCServer(("localhost", 8000))
-server.register_introspection_functions()
-server.register_instance(MyFuncs())
-server.serve_forever()
-
-3. Install an instance with custom dispatch method:
-
-class Math:
-    def _listMethods(self):
-        # this method must be present for system.listMethods
-        # to work
-        return ['add', 'pow']

-        elif method == 'pow':
-            return "pow(x, y[, z]) => number"
-        else:
-            # By convention, return empty
-            # string if no help is available

-
-server = SimpleXMLRPCServer(("localhost", 8000))
-server.register_introspection_functions()
-server.register_instance(Math())
-server.serve_forever()
-
-4. Subclass SimpleXMLRPCServer:
-
-class MathServer(SimpleXMLRPCServer):
-    def _dispatch(self, method, params):
-        try:
-            # We are forcing the 'export_' prefix on methods that are
-            # callable through XML-RPC to prevent potential security

-"""Generic socket server classes.
-
-This module tries to capture the various aspects of defining a server:
-
-For socket-based servers:
-
-- address family:
-        - AF_INET{,6}: IP (Internet Protocol) sockets (default)
-        - AF_UNIX: Unix domain sockets
-        - others, e.g. AF_DECNET are conceivable (see <socket.h>
-- socket type:
-        - SOCK_STREAM (reliable stream, e.g. TCP)
-        - SOCK_DGRAM (datagrams, e.g. UDP)
-
-For request-based servers (including socket-based):
-
-- client address verification before further looking at the request
-        (This is actually a hook for any processing that needs to look
-         at the request before anything else, e.g. logging)
-- how to handle multiple requests:
-        - synchronous (one request is handled at a time)
-        - forking (each request is handled by a new process)
-        - threading (each request is handled by a new thread)
-
-The classes in this module favor the server type that is simplest to
-write: a synchronous TCP/IP server.  This is bad class design, but
-save some typing.  (There's also the issue that a deep class hierarchy
-slows down method lookups.)
-
-There are five classes in an inheritance diagram, four of which represent
-synchronous servers of four types:
-
-        +------------+
-        | BaseServer |
-        +------------+
-              |
-              v
-        +-----------+        +------------------+
-        | TCPServer |------->| UnixStreamServer |
-        +-----------+        +------------------+
-              |
-              v
-        +-----------+        +--------------------+
-        | UDPServer |------->| UnixDatagramServer |
-        +-----------+        +--------------------+
-
-Note that UnixDatagramServer derives from UDPServer, not from
-UnixStreamServer -- the only difference between an IP and a Unix
-stream server is the address family, which is simply repeated in both
-unix server classes.
-
-Forking and threading versions of each type of server can be created
-using the ForkingMixIn and ThreadingMixIn mix-in classes.  For
-instance, a threading UDP server class is created as follows:
-
-        class ThreadingUDPServer(ThreadingMixIn, UDPServer): pass
-
-The Mix-in class must come first, since it overrides a method defined
-in UDPServer! Setting the various member variables also changes
-the behavior of the underlying server mechanism.
-
-To implement a service, you must derive a class from
-BaseRequestHandler and redefine its handle() method.  You can then run
-various versions of the service by combining one of the server classes
-with your request handler class.
-
-The request handler class must be different for datagram or stream
-services.  This can be hidden by using the request handler
-subclasses StreamRequestHandler or DatagramRequestHandler.
-
-Of course, you still have to use your head!
-
-For instance, it makes no sense to use a forking server if the service
-contains state in memory that can be modified by requests (since the
-modifications in the child process would never reach the initial state
-kept in the parent process and passed to each child).  In this case,
-you can use a threading server, but you will probably have to use
-locks to avoid two requests that come in nearly simultaneous to apply
-conflicting changes to the server state.
-
-On the other hand, if you are building e.g. an HTTP server, where all
-data is stored externally (e.g. in the file system), a synchronous
-class will essentially render the service "deaf" while one request is
-being handled -- which may be for a very long time if a client is slow
-to read all the data it has requested.  Here a threading or forking
-server is appropriate.
-
-In some cases, it may be appropriate to process part of a request
-synchronously, but to finish processing in a forked child depending on
-the request data.  This can be implemented by using a synchronous
-server and doing an explicit fork in the request handler class
-handle() method.
-
-Another approach to handling multiple simultaneous requests in an
-environment that supports neither threads nor fork (or where these are
-too expensive or inappropriate for the service) is to maintain an
-explicit table of partially finished requests and to use select() to
-decide which request to work on next (or whether to handle a new
-incoming request).  This is particularly important for stream services
-where each client can potentially be connected for a long time (if
-threads or subprocesses cannot be used).
-
-Future work:
-- Standard classes for Sun RPC (which uses either UDP or TCP)
-- Standard mix-in classes to implement various authentication
-  and encryption schemes
-- Standard framework for select-based multiplexing
-
-XXX Open problems:
-- What to do with out-of-band data?
-
-BaseServer:
-- split generic "request" functionality out into BaseServer class.

-
-    This class differs from CookieJar only in the format it uses to save and
-    load cookies to and from a file.  This class uses the Mozilla/Netscape
-    `cookies.txt' format.  lynx uses this file format, too.
-
-    Don't expect cookies saved while the browser is running to be noticed by
-    the browser (in fact, Mozilla on unix will overwrite your saved cookies if
-    you change them on disk while it's running; on Windows, you probably can't
-    save at all while the browser is running).
-
-    Note that the Mozilla/Netscape format will downgrade RFC2965 cookies to
-    Netscape cookies on saving.
-
-    In particular, the cookie version and port number information is lost,
-    together with information about whether or not Path, Port and Discard were
-    specified by the Set-Cookie2 (or Set-Cookie) header, and whether or not the
-    domain as set in the HTTP header started with a dot (yes, I'm aware some
-    domains in Netscape files start with a dot and some don't -- trust me, you
-    really don't want to know any more about this).
-
-    Note that though Mozilla and Netscape use the same format, they use

-"""Thread-local objects.
-
-(Note that this module provides a Python version of the threading.local
- class.  Depending on the version of Python you're using, there may be a
- faster one available.  You should always import the `local` class from
- `threading`.)
-
-Thread-local objects support the management of thread-local data.
-If you have data that you want to be local to a thread, simply create
-a thread-local object and use its attributes:
-
-  >>> mydata = local()
-  >>> mydata.number = 42
-  >>> mydata.number
-  42
-
-You can also access the local-object's dictionary:
-
-  >>> mydata.__dict__
-  {'number': 42}
-  >>> mydata.__dict__.setdefault('widgets', [])
-  []
-  >>> mydata.widgets
-  []
-
-What's important about thread-local objects is that their data are
-local to a thread. If we access the data in a different thread:
-
-  >>> log = []
-  >>> def f():
-  ...     items = mydata.__dict__.items()
-  ...     items.sort()
-  ...     log.append(items)
-  ...     mydata.number = 11
-  ...     log.append(mydata.number)
-
-  >>> import threading
-  >>> thread = threading.Thread(target=f)
-  >>> thread.start()
-  >>> thread.join()
-  >>> log
-  [[], 11]
-
-we get different data.  Furthermore, changes made in the other thread
-don't affect data seen in this thread:
-
-  >>> mydata.number
-  42
-
-Of course, values you get from a local object, including a __dict__
-attribute, are for whatever thread was current at the time the
-attribute was read.  For that reason, you generally don't want to save
-these values across threads, as they apply only to the thread they
-came from.
-
-You can create custom local objects by subclassing the local class:
-
-  >>> class MyLocal(local):
-  ...     number = 2
-  ...     initialized = False
-  ...     def __init__(self, **kw):
-  ...         if self.initialized:
-  ...             raise SystemError('__init__ called too many times')
-  ...         self.initialized = True
-  ...         self.__dict__.update(kw)
-  ...     def squared(self):
-  ...         return self.number ** 2
-
-This can be useful to support default values, methods and
-initialization.  Note that if you define an __init__ method, it will be
-called each time the local object is used in a separate thread.  This
-is necessary to initialize each thread's dictionary.
-
-Now if we create a local object:
-
-  >>> mydata = MyLocal(color='red')
-
-Now we have a default number:
-
-  >>> mydata.number
-  2
-
-an initial color:
-
-  >>> mydata.color
-  'red'
-  >>> del mydata.color
-
-And a method that operates on the data:
-
-  >>> mydata.squared()
-  4
-
-As before, we can access the data in a separate thread:
-
-  >>> log = []
-  >>> thread = threading.Thread(target=f)
-  >>> thread.start()
-  >>> thread.join()
-  >>> log
-  [[('color', 'red'), ('initialized', True)], 11]
-
-without affecting this thread's data:
-
-  >>> mydata.number
-  2
-  >>> mydata.color
-  Traceback (most recent call last):
-  ...
-  AttributeError: 'MyLocal' object has no attribute 'color'
-
-Note that subclasses can define slots, but they are not thread
-local. They are shared across threads:
-
-  >>> class MyLocal(local):
-  ...     __slots__ = 'number'
-
-  >>> mydata = MyLocal()
-  >>> mydata.number = 42
-  >>> mydata.color = 'red'
-
-So, the separate thread:
-
-  >>> thread = threading.Thread(target=f)
-  >>> thread.start()
-  >>> thread.join()
-
-affects what we see:
-
-  >>> mydata.number
-  11
-
->>> del mydata
-"""

-__all__ = ["local"]

-# We need to use objects from the threading module, but the threading
-# module may also want to use our `local` class, if support for locals
-# isn't compiled in to the `thread` module.  This creates potential problems
-# with circular imports.  For that reason, we don't import `threading`
-# until the bottom of this file (a hack sufficient to worm around the
-# potential problems).  Note that almost all platforms do have support for
-# locals in the `thread` module, and there is no circular import problem
-# then, so problems introduced by fiddling the order of imports here won't
-# manifest on most boxes.

-"""Stuff to parse AIFF-C and AIFF files.
-
-Unless explicitly stated otherwise, the description below is true
-both for AIFF-C files and AIFF files.
-
-An AIFF-C file has the following structure.
-
-  +-----------------+
-  | FORM            |
-  +-----------------+
-  | <size>          |
-  +----+------------+
-  |    | AIFC       |
-  |    +------------+
-  |    | <chunks>   |
-  |    |    .       |
-  |    |    .       |
-  |    |    .       |
-  +----+------------+
-
-An AIFF file has the string "AIFF" instead of "AIFC".
-
-A chunk consists of an identifier (4 bytes) followed by a size (4 bytes,
-big endian order), followed by the data.  The size field does not include
-the size of the 8 byte header.
-
-The following chunk types are recognized.
-
-  FVER
-      <version number of AIFF-C defining document> (AIFF-C only).
-  MARK
-      <# of markers> (2 bytes)
-      list of markers:
-          <marker ID> (2 bytes, must be > 0)
-          <position> (4 bytes)
-          <marker name> ("pstring")
-  COMM
-      <# of channels> (2 bytes)
-      <# of sound frames> (4 bytes)
-      <size of the samples> (2 bytes)
-      <sampling frequency> (10 bytes, IEEE 80-bit extended
-          floating point)
-      in AIFF-C files only:
-      <compression type> (4 bytes)
-      <human-readable version of compression type> ("pstring")
-  SSND
-      <offset> (4 bytes, not used by this program)
-      <blocksize> (4 bytes, not used by this program)
-      <sound data>
-
-A pstring consists of 1 byte length, a string of characters, and 0 or 1
-byte pad to make the total length even.
-
-Usage.
-
-Reading AIFF files:
-  f = aifc.open(file, 'r')
-where file is either the name of a file or an open file pointer.
-The open file pointer must have methods read(), seek(), and close().
-In some types of audio files, if the setpos() method is not used,
-the seek() method is not necessary.
-
-This returns an instance of a class with the following public methods:
-  getnchannels()  -- returns number of audio channels (1 for
-             mono, 2 for stereo)
-  getsampwidth()  -- returns sample width in bytes
-  getframerate()  -- returns sampling frequency
-  getnframes()    -- returns number of audio frames
-  getcomptype()   -- returns compression type ('NONE' for AIFF files)
-  getcompname()   -- returns human-readable version of
-             compression type ('not compressed' for AIFF files)
-  getparams() -- returns a tuple consisting of all of the
-             above in the above order
-  getmarkers()    -- get the list of marks in the audio file or None
-             if there are no marks
-  getmark(id) -- get mark with the specified id (raises an error
-             if the mark does not exist)
-  readframes(n)   -- returns at most n frames of audio
-  rewind()    -- rewind to the beginning of the audio stream
-  setpos(pos) -- seek to the specified position
-  tell()      -- return the current position
-  close()     -- close the instance (make it unusable)
-The position returned by tell(), the position given to setpos() and
-the position of marks are all compatible and have nothing to do with
-the actual position in the file.
-The close() method is called automatically when the class instance
-is destroyed.
-
-Writing AIFF files:
-  f = aifc.open(file, 'w')
-where file is either the name of a file or an open file pointer.
-The open file pointer must have methods write(), tell(), seek(), and
-close().
-
-This returns an instance of a class with the following public methods:
-  aiff()      -- create an AIFF file (AIFF-C default)
-  aifc()      -- create an AIFF-C file
-  setnchannels(n) -- set the number of channels
-  setsampwidth(n) -- set the sample width
-  setframerate(n) -- set the frame rate
-  setnframes(n)   -- set the number of frames
-  setcomptype(type, name)
-          -- set the compression type and the
-             human-readable compression type
-  setparams(tuple)
-          -- set all parameters at once
-  setmark(id, pos, name)
-          -- add specified mark to the list of marks
-  tell()      -- return current position in output file (useful
-             in combination with setmark())
-  writeframesraw(data)
-          -- write audio frames without pathing up the
-             file header
-  writeframes(data)
-          -- write audio frames and patch up the file header
-  close()     -- patch up the file header and close the
-             output file
-You should set the parameters before the first writeframesraw or
-writeframes.  The total number of frames does not need to be set,
-but when it is set to the correct value, the header does not have to
-be patched up.
-It is best to first set all parameters, perhaps possibly the
-compression type, and then write audio frames using writeframesraw.
-When all frames have been written, either call writeframes('') or
-close() to patch up the sizes in the header.
-Marks can be added anytime.  If there are any marks, you must call
-close() after all frames have been written.
-The close() method is called automatically when the class instance
-is destroyed.
-
-When a file is opened with the extension '.aiff', an AIFF file is
-written, otherwise an AIFF-C file is written.  This default can be
-changed by calling aiff() or aifc() before the first writeframes or
-writeframesraw.

-    ast
-    ~~~
-
-    The `ast` module helps Python applications to process trees of the Python
-    abstract syntax grammar.  The abstract syntax itself might change with
-    each Python release; this module helps to find out programmatically what
-    the current grammar looks like and allows modifications of it.
-
-    An abstract syntax tree can be generated by passing `ast.PyCF_ONLY_AST` as
-    a flag to the `compile()` builtin function or by using the `parse()`
-    function from this module.  The result will be a tree of objects whose
-    classes all inherit from `ast.AST`.
-
-    A modified abstract syntax tree can be compiled into a Python code object
-    using the built-in `compile()` function.
-
-    Additionally various helper functions are provided that make working with
-    the trees simpler.  The main intention of the helper functions and this
-    module in general is to provide an easy to use interface for libraries
-    that work tightly with the python syntax (template engines for example).

-
-    This class is meant to be subclassed, with the subclass adding visitor
-    methods.
-
-    Per default the visitor functions for the nodes are ``'visit_'`` +
-    class name of the node.  So a `TryFinally` node visit function would
-    be `visit_TryFinally`.  This behavior can be changed by overriding
-    the `visit` method.  If no visitor function exists for a node
-    (return value `None`) the `generic_visit` visitor is used instead.

-    """
-    A :class:`NodeVisitor` subclass that walks the abstract syntax tree and
-    allows modification of nodes.
-
-    The `NodeTransformer` will walk the AST and use the return value of the
-    visitor methods to replace or remove the old node.  If the return value of
-    the visitor method is ``None``, the node will be removed from its location,
-    otherwise it is replaced with the return value.  The return value may be the
-    original node in which case no replacement takes place.
-
-    Here is an example transformer that rewrites all occurrences of name lookups
-    (``foo``) to ``data['foo']``::
-
-       class RewriteName(NodeTransformer):
-
-           def visit_Name(self, node):

-                   ctx=node.ctx
-               ), node)
-
-    Keep in mind that if the node you're operating on has child nodes you must
-    either transform the child nodes yourself or call the :meth:`generic_visit`
-    method for the node first.
-
-    For nodes that were part of a collection of statements (that applies to all
-    statement nodes), the visitor may also return a list of nodes rather than
-    just a single node.
-
-    Usually you use the transformer like this::

-       node = YourTransformer().visit(node)

-
-    This class provides naming, typing, files stored on disk, and
-    more.  At the top level, it is accessible like a dictionary, whose
-    keys are the field names.  (Note: None can occur as a field name.)
-    The items are either a Python list (if there's multiple values) or
-    another FieldStorage or MiniFieldStorage object.  If it's a single
-    object, it has the following attributes:
-
-    name: the field name, if specified; otherwise None
-
-    filename: the filename, if specified; otherwise None; this is the
-        client side filename, *not* the file name on which it is
-        stored (that's a temporary file you don't deal with)
-
-    value: the value as a *string*; for file uploads, this
-        transparently reads the file every time you request the value
-
-    file: the file(-like) object from which you can read the data;
-        None if the data is stored a simple string
-
-    type: the content-type, or None if not specified
-
-    type_options: dictionary of options specified on the content-type
-        line
-
-    disposition: content-disposition, or None if not specified
-
-    disposition_options: dictionary of corresponding options
-
-    headers: a dictionary(-like) object (sometimes rfc822.Message or a
-        subclass thereof) containing *all* headers
-
-    The class is subclassable, mostly for the purpose of overriding
-    the make_file() method, which is called internally to come up with
-    a file open for reading and writing.  This makes it possible to
-    override the default choice of storing all files in a temporary
-    directory and unlinking them as soon as they have been opened.

-"""A generic class to build line-oriented command interpreters.
-
-Interpreters constructed with this class obey the following conventions:
-
-1. End of file on input is processed as the command 'EOF'.
-2. A command is parsed out of each line by collecting the prefix composed
-   of characters in the identchars member.
-3. A command `foo' is dispatched to a method 'do_foo()'; the do_ method
-   is passed a single argument consisting of the remainder of the line.
-4. Typing an empty line repeats the last command.  (Actually, it calls the
-   method `emptyline', which may be overridden in a subclass.)
-5. There is a predefined `help' method.  Given an argument `topic', it
-   calls the command `help_topic'.  With no arguments, it lists all topics
-   with defined help_ functions, broken into up to three topics; documented
-   commands, miscellaneous help topics, and undocumented commands.
-6. The command '?' is a synonym for `help'.  The command '!' is a synonym
-   for `shell', if a do_shell method exists.
-7. If completion is enabled, completing commands will be done automatically,
-   and completing of commands args is done by calling complete_foo() with
-   arguments text, line, begidx, endidx.  text is string we are matching
-   against, all returned matches must begin with it.  line is the current
-   input line (lstripped), begidx and endidx are the beginning and end
-   indexes of the text being matched, which could be used to provide
-   different completion depending upon which position the argument is in.
-
-The `default' method may be overridden to intercept commands for which there
-is no do_ method.
-
-The `completedefault' method may be overridden to intercept completions for
-commands that have no complete_ method.
-
-The data member `self.ruler' sets the character used to draw separator lines
-in the help messages.  If empty, no ruler line is drawn.  It defaults to "=".
-
-If the value of `self.intro' is nonempty when the cmdloop method is called,
-it is printed out on interpreter startup.  This value may be overridden
-via an optional argument to the cmdloop() method.
-
-The data members `self.doc_header', `self.misc_header', and
-`self.undoc_header' set the headers used for the help function's
-listings of documented functions, miscellaneous topics, and undocumented
-functions respectively.
-
-These interpreters use raw_input; thus, if the readline module is loaded,
-they automatically support Emacs-like command history and editing features.

-class ASTVisitor:
-    """Performs a depth-first walk of the AST
-
-    The ASTVisitor will walk the AST, performing either a preorder or
-    postorder traversal depending on which method is called.
-
-    methods:
-    preorder(tree, visitor)
-    postorder(tree, visitor)
-        tree: an instance of ast.Node
-        visitor: an instance with visitXXX methods
-
-    The ASTVisitor is responsible for walking over the tree in the
-    correct order.  For each node, it checks the visitor argument for
-    a method named 'visitNodeType' where NodeType is the name of the
-    node's class, e.g. Class.  If the method exists, it is called
-    with the node as its sole argument.
-
-    The visitor method for a particular node type can control how
-    child nodes are visited during a preorder walk.  (It can't control
-    the order during a postorder walk, because it is called _after_
-    the walk has occurred.)  The ASTVisitor modifies the visitor
-    argument by adding a visit method to the visitor; this method can
-    be used to visit a child node of arbitrary type.

-# Generated automatically from Makefile.pre by makesetup.
-# Top-level Makefile for Python
-#
-# As distributed, this file is called Makefile.pre.in; it is processed
-# into the real Makefile by running the script ./configure, which
-# replaces things like @spam@ with values appropriate for your system.
-# This means that if you edit Makefile, your changes get lost the next
-# time you run the configure script.  Ideally, you can do:
-#
-#	./configure
-#	make
-#	make test
-#	make install
-#
-# If you have a previous version of Python installed that you don't
-# want to overwrite, you can use "make altinstall" instead of "make
-# install".  Refer to the "Installing" section in the README file for
-# additional details.
-#
-# See also the section "Build instructions" in the README file.

-# -*- makefile -*-
-# The file Setup is used by the makesetup script to construct the files
-# Makefile and config.c, from Makefile.pre and config.c.in,
-# respectively.  The file Setup itself is initially copied from
-# Setup.dist; once it exists it will not be overwritten, so you can edit
-# Setup to your heart's content.  Note that Makefile.pre is created
-# from Makefile.pre.in by the toplevel configure script.
-
-# (VPATH notes: Setup and Makefile.pre are in the build directory, as
-# are Makefile and config.c; the *.in and *.dist files are in the source
-# directory.)
-
-# Each line in this file describes one or more optional modules.
-# Modules enabled here will not be compiled by the setup.py script,
-# so the file can be used to override setup.py's behavior.
-
-# Lines have the following structure:
-#
-# <module> ... [<sourcefile> ...] [<cpparg> ...] [<library> ...]
-#
-# <sourcefile> is anything ending in .c (.C, .cc, .c++ are C++ files)
-# <cpparg> is anything starting with -I, -D, -U or -C
-# <library> is anything ending in .a or beginning with -l or -L
-# <module> is anything else but should be a valid Python
-# identifier (letters, digits, underscores, beginning with non-digit)
-#
-# (As the makesetup script changes, it may recognize some other
-# arguments as well, e.g. *.so and *.sl as libraries.  See the big
-# case statement in the makesetup script.)
-#
-# Lines can also have the form
-#
-# <name> = <value>
-#
-# which defines a Make variable definition inserted into Makefile.in
-#
-# Finally, if a line contains just the word "*shared*" (without the
-# quotes but with the stars), then the following modules will not be
-# built statically.  The build process works like this:
-#
-# 1. Build all modules that are declared as static in Modules/Setup,
-#    combine them into libpythonxy.a, combine that into python.
-# 2. Build all modules that are listed as shared in Modules/Setup.
-# 3. Invoke setup.py. That builds all modules that
-#    a) are not builtin, and
-#    b) are not listed in Modules/Setup, and
-#    c) can be build on the target
-#
-# Therefore, modules declared to be shared will not be
-# included in the config.c file, nor in the list of objects to be
-# added to the library archive, and their linker options won't be
-# added to the linker options. Rules to create their .o files and
-# their shared libraries will still be added to the Makefile, and
-# their names will be collected in the Make variable SHAREDMODS.  This
-# is used to build modules as shared libraries.  (They can be
-# installed using "make sharedinstall", which is implied by the
-# toplevel "make install" target.)  (For compatibility,
-# *noconfig* has the same effect as *shared*.)
-#
-# In addition, *static* explicitly declares the following modules to
-# be static.  Lines containing "*static*" and "*shared*" may thus
-# alternate throughout this file.
-
-# NOTE: As a standard policy, as many modules as can be supported by a
-# platform should be present.  The distribution comes with all modules
-# enabled that are supported by most platforms and don't require you
-# to ftp sources from elsewhere.

-"""Generic (shallow and deep) copying operations.
-
-Interface summary:
-
-        import copy
-
-        x = copy.copy(y)        # make a shallow copy of y
-        x = copy.deepcopy(y)    # make a deep copy of y
-
-For module specific errors, copy.Error is raised.
-
-The difference between shallow and deep copying is only relevant for
-compound objects (objects that contain other objects, like lists or
-class instances).
-
-- A shallow copy constructs a new compound object and then (to the
-  extent possible) inserts *the same objects* into it that the
-  original contains.
-
-- A deep copy constructs a new compound object and then, recursively,
-  inserts *copies* into it of the objects found in the original.
-
-Two problems often exist with deep copy operations that don't exist
-with shallow copy operations:
-
- a) recursive objects (compound objects that, directly or indirectly,
-    contain a reference to themselves) may cause a recursive loop
-
- b) because deep copy copies *everything* it may copy too much, e.g.
-    administrative data structures that should be shared even between
-    copies
-
-Python's deep copy operation avoids these problems by:
-
- a) keeping a table of objects already copied during the current
-    copying pass
-
- b) letting user-defined classes override the copying operation or the
-    set of components copied
-
-This version does not copy types like module, class, function, method,
-nor stack trace, stack frame, nor file, socket, window, nor array, nor
-any similar types.
-
-Classes can use the same interfaces to control copying that they use
-to control pickling: they can define methods called __getinitargs__(),
-__getstate__() and __setstate__().  See the documentation for module
-"pickle" for information on these methods.

-# * We put export_symbols in a def-file, and don't use

-#   tested configurations. And because other windows compilers also
-#   need their symbols specified this no serious problem.

-# * cygwin gcc 2.95.2/ld 2.10.90/dllwrap 2.10.90 works now

-#     see also http://sources.redhat.com/ml/cygwin/2000-06/msg01274.html

-#     By specifying -static we force ld to link against the import libraries,

-class Extension:
-    """Just a collection of attributes that describes an extension
-    module and everything needed to build it (hopefully in a portable
-    way, but there are hooks that let you be as unportable as you need).
-
-    Instance attributes:
-      name : string
-        the full name of the extension, including any packages -- ie.
-        *not* a filename or pathname, but Python dotted name
-      sources : [string]
-        list of source filenames, relative to the distribution root
-        (where the setup script lives), in Unix form (slash-separated)
-        for portability.  Source files may be C, C++, SWIG (.i),
-        platform-specific resource files, or whatever else is recognized
-        by the "build_ext" command as source for a Python extension.
-      include_dirs : [string]
-        list of directories to search for C/C++ header files (in Unix
-        form for portability)
-      define_macros : [(name : string, value : string|None)]
-        list of macros to define; each macro is defined using a 2-tuple,
-        where 'value' is either the string to define it to or None to
-        define it without a particular value (equivalent of "#define
-        FOO" in source or -DFOO on Unix C compiler command line)
-      undef_macros : [string]
-        list of macros to undefine explicitly
-      library_dirs : [string]
-        list of directories to search for C/C++ libraries at link time
-      libraries : [string]
-        list of library names (not filenames or paths) to link against
-      runtime_library_dirs : [string]
-        list of directories to search for C/C++ libraries at run time
-        (for shared extensions, this is when the extension is loaded)
-      extra_objects : [string]
-        list of extra files to link with (eg. object files not implied
-        by 'sources', static library that must be explicitly specified,
-        binary resource files, etc.)
-      extra_compile_args : [string]
-        any extra platform- and compiler-specific information to use
-        when compiling the source files in 'sources'.  For platforms and
-        compilers where "command line" makes sense, this is typically a
-        list of command-line arguments, but for other platforms it could
-        be anything.
-      extra_link_args : [string]
-        any extra platform- and compiler-specific information to use
-        when linking object files together to create the extension (or
-        to create a new static Python interpreter).  Similar
-        interpretation as for 'extra_compile_args'.
-      export_symbols : [string]
-        list of symbols to be exported from a shared extension.  Not
-        used on all platforms, and not generally necessary for Python
-        extensions, which typically export exactly one symbol: "init" +
-        extension_name.
-      swig_opts : [string]
-        any extra options to pass to SWIG if a source file has the .i
-        extension.
-      depends : [string]
-        list of files that the extension depends on
-      language : string
-        extension language (i.e. "c", "c++", "objc"). Will be detected
-        from the source extensions if not provided.

-    Implements the standard interface for version number classes as
-    described above.  A version number consists of two or three
-    dot-separated numeric components, with an optional "pre-release" tag
-    on the end.  The pre-release tag consists of the letter 'a' or 'b'
-    followed by a number.  If the numeric components of two version
-    numbers are equal, then one with a pre-release tag will always
-    be deemed earlier (lesser) than one without.
-
-    The following are valid version numbers (shown in the order that
-    would be obtained by sorting according to the supplied cmp function):
-
-        0.4       0.4.0  (these two are equivalent)
-        0.4.1
-        0.5a1
-        0.5b3
-        0.5
-        0.9.6
-        1.0
-        1.0.4a3
-        1.0.4b1
-        1.0.4
-
-    The following are examples of invalid version numbers:
-
-        1
-        2.7.2.2
-        1.3.a4
-        1.3pl1
-        1.3c4
-
-    The rationale for this version numbering system will be explained
-    in the distutils documentation.

-
-# The rules according to Greg Stein:
-# 1) a version number has 1 or more numbers separated by a period or by
-#    sequences of letters. If only periods, then these are compared
-#    left-to-right to determine an ordering.
-# 2) sequences of letters are part of the tuple for comparison and are
-#    compared lexicographically
-# 3) recognize the numeric components may have leading zeroes
-#
-# The LooseVersion class below implements these rules: a version number
-# string is split up into a tuple of integer and string components, and
-# comparison is a simple tuple comparison.  This means that version
-# numbers behave in a predictable and obvious way, but a way that might
-# not necessarily be how people *want* version numbers to behave.  There
-# wouldn't be a problem if people could stick to purely numeric version
-# numbers: just split on period and compare the numbers as tuples.
-# However, people insist on putting letters into their version numbers;
-# the most common purpose seems to be:
-#   - indicating a "pre-release" version
-#     ('alpha', 'beta', 'a', 'b', 'pre', 'p')
-#   - indicating a post-release patch ('p', 'pl', 'patch')
-# but of course this can't cover all version number schemes, and there's
-# no way to know what a programmer means without asking him.
-#
-# The problem is what to do with letters (and other non-numeric
-# characters) in a version number.  The current implementation does the
-# obvious and predictable thing: keep them as strings and compare
-# lexically within a tuple comparison.  This has the desired effect if
-# an appended letter sequence implies something "post-release":
-# eg. "0.99" < "0.99pl14" < "1.0", and "5.001" < "5.001m" < "5.002".
-#
-# However, if letters in a version number imply a pre-release version,
-# the "obvious" thing isn't correct.  Eg. you would expect that
-# "1.5.1" < "1.5.2a2" < "1.5.2", but under the tuple/lexical comparison
-# implemented here, this just isn't so.
-#
-# Two possible solutions come to mind.  The first is to tie the
-# comparison algorithm to a particular set of semantic rules, as has
-# been done in the StrictVersion class above.  This works great as long
-# as everyone can go along with bondage and discipline.  Hopefully a
-# (large) subset of Python module programmers will agree that the
-# particular flavour of bondage and discipline provided by StrictVersion
-# provides enough benefit to be worth using, and will submit their
-# version numbering scheme to its domination.  The free-thinking
-# anarchists in the lot will never give in, though, and something needs
-# to be done to accommodate them.
-#
-# Perhaps a "moderately strict" version class could be implemented that
-# lets almost anything slide (syntactically), and makes some heuristic
-# assumptions about non-digits in version number strings.  This could
-# sink into special-case-hell, though; if I was as talented and
-# idiosyncratic as Larry Wall, I'd go ahead and implement a class that
-# somehow knows that "1.2.1" < "1.2.2a2" < "1.2.2" < "1.2.2pl3", and is
-# just as happy dealing with things like "2g6" and "1.13++".  I don't
-# think I'm smart enough to do it right though.
-#
-# In any case, I've coded the test suite for this module (see
-# ../test/test_version.py) specifically to fail on things like comparing
-# "1.2a2" and "1.2".  That's not because the *code* is doing anything
-# wrong, it's because the simple, obvious design doesn't match my
-# complicated, hairy expectations for real-world version numbers.  It
-# would be a snap to fix the test suite to say, "Yep, LooseVersion does
-# the Right Thing" (ie. the code matches the conception).  But I'd rather
-# have a conception that matches common notions about version numbers.

-r"""Module doctest -- a framework for running examples in docstrings.
-
-In simplest use, end each module M to be tested with:
-
-def _test():
-    import doctest
-    doctest.testmod()
-
-if __name__ == "__main__":
-    _test()
-
-Then running the module as a script will cause the examples in the
-docstrings to get executed and verified:
-
-python M.py
-
-This won't display anything unless an example fails, in which case the
-failing example(s) and the cause(s) of the failure(s) are printed to stdout
-(why not stderr? because stderr is a lame hack <0.2 wink>), and the final
-line of output is "Test failed.".
-
-Run it with the -v switch instead:
-
-python M.py -v
-
-and a detailed report of all examples tried is printed to stdout, along
-with assorted summaries at the end.
-
-You can force verbose mode by passing "verbose=True" to testmod, or prohibit
-it by passing "verbose=False".  In either of those cases, sys.argv is not
-examined by testmod.
-
-There are a variety of other ways to run doctests, including integration
-with the unittest framework, and support for running non-Python text
-files containing doctests.  There are also many ways to override parts
-of doctest's default behaviors.  See the Library Reference Manual for
-details.

-######################################################################
-## - An "example" is a <source, want> pair, where "source" is a
-##   fragment of source code, and "want" is the expected output for
-##   "source."  The Example class also includes information about
-##   where the example was extracted from.
-##
-## - A "doctest" is a collection of examples, typically extracted from
-##   a string (such as an object's docstring).  The DocTest class also
-##   includes information about where the string was extracted from.

-        The constructor adds a newline if needed.
-
-      - want: The expected output from running the source code (either
-        from stdout, or a traceback in case of exception).  `want` ends
-        with a newline unless it's empty, in which case it's an empty
-        string.  The constructor adds a newline if needed.

-        this Example where the Example begins.  This line number is
-        zero-based, with respect to the beginning of the DocTest.

-        I.e., the number of space characters that precede the
-        example's first prompt.
-
-      - options: A dictionary mapping from option flags to True or
-        False, which is used to override default options for this
-        example.  Any option flags not contained in this dictionary
-        are left at their default value (as specified by the

-            - As a default namespace, if `globs` is not specified.

-    converted outright, and are not allowed in email.  Instances of this

-
-    input_charset: The initial character set specified.  Common aliases
-                   are converted to their `official' email names (e.g. latin_1
-                   is converted to iso-8859-1).  Defaults to 7-bit us-ascii.

-                     QP or BASE64 encoding.  Otherwise, it will be None.
-
-    body_encoding: Same as header_encoding, but describes the encoding for the
-                   mail message's body, which indeed may be different than the
-                   header encoding.  Charset.SHORTEST is not allowed for
-                   body_encoding.

-                    one of them, this attribute will contain the name of the
-                    charset output will be converted to.  Otherwise, it will
-                    be None.
-
-    input_codec: The name of the Python codec used to convert the

-        7-bit ASCII, care must be taken to properly convert and encode (with
-        Base64 or quoted-printable) header strings.  In addition, there is a
-        75-character length limit on any given encoded header field, so
-        line-wrapping must be performed, even with double-byte character sets.
-
-        This method will do its best to convert the string to the correct
-        character set used in email, and encode and line wrap it safely with
-        the appropriate scheme for that character set.
-
-        If the given charset is not known or an error occurs during
-        conversion, this function will return the header untouched.
-
-        Optional splitchars is a string containing characters to split long
-        ASCII lines on, in rough support of RFC 2822's `highest level
-        syntactic breaks'.  This doesn't affect RFC 2047 encoded lines.

-This module handles the content transfer encoding method defined in RFC 2045
-to encode US ASCII-like 8-bit data called `quoted-printable'.  It is used to
-safely encode text that is in a character set similar to the 7-bit US ASCII
-character set, but that includes some 8-bit characters that are normally not
-allowed in email bodies or headers.
-
-Quoted-printable is very space-inefficient for encoding binary files; use the

-
-This module provides an interface to encode and decode both headers and bodies
-with quoted-printable encoding.

-RFC 2045 defines a method for including character set information in an
-`encoded-word' in a header.  This method is commonly used for 8-bit real names
-in To:/From:/Cc: etc. fields, as well as Subject: lines.
-
-This module does not do the line wrapping or end-of-line character
-conversion necessary for proper internationalized headers; it only
-does dumb encoding and decoding.  To deal with the various line

-
-    Codec modules must have names corresponding to normalized encoding
-    names as defined in the normalize_encoding() function below, e.g.
-    'utf-8' must be implemented by the module 'utf_8.py'.
-

-    * getregentry() -> codecs.CodecInfo object
-    The getregentry() API must a CodecInfo object with encoder, decoder,
-    incrementalencoder, incrementaldecoder, streamwriter and streamreader
-    atttributes which adhere to the Python Codec Interface Standard.
-
-    In addition, a module may optionally also define the following
-    APIs which are then used by the package's codec search function:
-
-    * getaliases() -> sequence of encoding name strings to use as aliases
-
-    Alias names returned by getaliases() must be normalized encoding

-
-        Securing the data connection requires user to explicitly ask

-        >>> ftps = FTP_TLS('ftp.python.org')
-        >>> ftps.login()  # login anonymously previously securing control channel
-        '230 Guest login ok, access restrictions apply.'
-        >>> ftps.prot_p()  # switch to secure data connection
-        '200 Protection level set to P'
-        >>> ftps.retrlines('LIST')  # list directory content securely

-
-        At least one of fileobj and filename must be given a
-        non-trivial value.
-
-        The new class instance is based on fileobj, which can be a regular
-        file, a StringIO object, or any other object which simulates a file.
-        It defaults to None, in which case filename is opened to provide
-        a file object.
-
-        When fileobj is not None, the filename argument is only used to be
-        included in the gzip file header, which may includes the original
-        filename of the uncompressed file.  It defaults to the filename of
-        fileobj, if discernible; otherwise, it defaults to the empty string,
-        and in this case the original filename is not included in the header.
-
-        The mode argument can be any of 'r', 'rb', 'a', 'ab', 'w', or 'wb',
-        depending on whether the file will be read or written.  The default
-        is the mode of fileobj if discernible; otherwise, the default is 'rb'.
-        Be aware that only the 'rb', 'ab', and 'wb' values should be used
-        for cross-platform portability.
-
-        The compresslevel argument is an integer from 0 to 9 controlling the
-        level of compression; 1 is fastest and produces the least compression,
-        and 9 is slowest and produces the most compression. 0 is no compression
-        at all. The default is 9.
-
-        The mtime argument is an optional numeric timestamp to be written
-        to the stream when compressing.  All gzip compressed streams
-        are required to contain a timestamp.  If omitted or None, the
-        current time is used.  This module ignores the timestamp when
-        decompressing; however, some programs, such as gunzip, make use
-        of it.  The format of the timestamp is the same as that of the
-        return value of time.time() and of the st_mtime member of the
-        object returned by os.stat().

-__doc__ = """hashlib module - A common interface to many hash functions.
-
-new(name, string='') - returns a new hash object implementing the
-                       given hash function; initializing the hash
-                       using the given string data.
-
-Named constructor functions are also available, these are much faster
-than using new():
-
-md5(), sha1(), sha224(), sha256(), sha384(), and sha512()
-
-More algorithms may be available on your platform but the above are
-guaranteed to exist.
-
-NOTE: If you want the adler32 or crc32 hash functions they are available in
-the zlib module.
-
-Choose your hash function wisely.  Some have known collision weaknesses.
-sha384 and sha512 will be slow on 32 bit platforms.
-
-Hash objects have these methods:
- - update(arg): Update the hash object with the string arg. Repeated calls
-                are equivalent to a single call with the concatenation of all
-                the arguments.
- - digest():    Return the digest of the strings passed to the update() method
-                so far. This may contain non-ASCII characters, including
-                NUL bytes.
- - hexdigest(): Like digest() except the digest is returned as a string of
-                double length, containing only hexadecimal digits.
- - copy():      Return a copy (clone) of the hash object. This can be used to
-                efficiently compute the digests of strings that share a common
-                initial substring.
-
-For example, to obtain the digest of the string 'Nobody inspects the
-spammish repetition':
-
-    >>> import hashlib
-    >>> m = hashlib.md5()
-    >>> m.update("Nobody inspects")
-    >>> m.update(" the spammish repetition")
-    >>> m.digest()
-    '\\xbbd\\x9c\\x83\\xdd\\x1e\\xa5\\xc9\\xd9\\xde\\xc9\\xa1\\x8d\\xf0\\xff\\xe9'
-
-More condensed:
-
-    >>> hashlib.sha224("Nobody inspects the spammish repetition").hexdigest()
-    'a4337bc45a8fc544c03f52dc550cd6e1e87021bc896588bd79e901e2'

-<intro stuff goes here>
-<other stuff, too>
-
-HTTPConnection goes through a number of "states", which define when a client
-may legally make another request or fetch the response for a particular
-request. This diagram details these state transitions:
-
-    (null)
-      |
-      | HTTPConnection()
-      v
-    Idle
-      |
-      | putrequest()
-      v
-    Request-started
-      |
-      | ( putheader() )*  endheaders()
-      v
-    Request-sent
-      |
-      | response = getresponse()
-      v
-    Unread-response   [Response-headers-read]
-      |\____________________
-      |                     |
-      | response.read()     | putrequest()
-      v                     v
-    Idle                  Req-started-unread-response
-                     ______/|
-                   /        |
-   response.read() |        | ( putheader() )*  endheaders()
-                   v        v
-       Request-started    Req-sent-unread-response
-                            |
-                            | response.read()
-                            v
-                          Request-sent
-
-This diagram presents the following rules:
-  -- a second request may not be started until {response-headers-read}
-  -- a response [object] cannot be retrieved until {request-sent}
-  -- there is no differentiation between an unread response body and a
-     partially read response body
-
-Note: this enforcement is applied by the HTTPConnection class. The
-      HTTPResponse class does not enforce this state machine, which
-      implies sophisticated clients may accelerate the request/response
-      pipeline. Caution should be taken, though: accelerating the states
-      beyond the above pattern may imply knowledge of the server's
-      connection-close behavior for certain requests. For example, it
-      is impossible to tell whether the server will close the connection
-      UNTIL the response headers have been read; this means that further
-      requests cannot be placed into the pipeline until it is known that
-      the server will NOT be closing the connection.

-# changes by dscherer@cmu.edu
-#   - IOBinding.open() replaces the current window with the opened file,
-#     if the current window is both unmodified and unnamed
-#   - IOBinding.loadfile() interprets Windows, UNIX, and Macintosh
-#     end-of-line conventions, instead of relying on the standard library,
-#     which will only understand the local convention.

-IDLE is Python's Tkinter-based Integrated DeveLopment Environment.
-
-IDLE emphasizes a lightweight, clean design with a simple user interface.
-Although it is suitable for beginners, even advanced users will find that
-IDLE has everything they really need to develop pure Python code.
-
-IDLE features a multi-window text editor with multiple undo, Python colorizing,
-and many other capabilities, e.g. smart indent, call tips, and autocompletion.
-
-The editor has comprehensive search functions, including searching through
-multiple files.  Class browsers and path browsers provide fast access to
-code objects from a top level viewpoint without dealing with code folding.
-
-There is a Python Shell window which features colorizing and command recall.
-
-IDLE executes Python code in a separate process, which is restarted for each
-Run (F5) initiated from an editor window.  The environment can also be 
-restarted from the Shell window without restarting IDLE.
-
-This enhancement has often been requested, and is now finally available.  The
-magic "reload/import *" incantations are no longer required when editing and
-testing a module two or three steps down the import chain.
-
-(Personal firewall software may warn about the connection IDLE makes to its
-subprocess using this computer's internal loopback interface.  This connection
-is not visible on any external interface and no data is sent to or received
-from the Internet.)
-
-It is possible to interrupt tightly looping user code, even on Windows.
-
-Applications which cannot support subprocesses and/or sockets can still run
-IDLE in a single process.
-
-IDLE has an integrated debugger with stepping, persistent breakpoints, and call
-stack visibility.
-
-There is a GUI configuration manager which makes it easy to select fonts,
-colors, keybindings, and startup options.  This facility includes a feature
-which allows the user to specify additional help sources, either locally or on
-the web.
-
-IDLE is coded in 100% pure Python, using the Tkinter GUI toolkit (Tk/Tcl)
-and is cross-platform, working on Unix, Mac, and Windows.
-
-IDLE accepts command line arguments.  Try idle -h to see the options.
-
-
-If you find bugs or have suggestions, let us know about them by using the
-Python Bug Tracker:
-
-http://sourceforge.net/projects/python
-
-Patches are always appreciated at the Python Patch Tracker, and change
-requests should be posted to the RFE Tracker.
-
-For further details and links, read the Help files and check the IDLE home
-page at
-
-http://www.python.org/idle/
-
-There is a mail list for IDLE: idle-dev@python.org.  You can join at

-** TIPS **
-==========
-
-Additional Help Sources:
-
-	Windows users can Google on zopeshelf.chm to access Zope help files in
-	the Windows help format.  The Additional Help Sources feature of the
-	configuration GUI supports .chm, along with any other filetypes
-	supported by your browser.  Supply a Menu Item title, and enter the
-	location in the Help File Path slot of the New Help Source dialog.  Use
-	http:// and/or www. to identify external URLs, or download the file and
-	browse for its path on your machine using the Browse button.
-
-	All users can access the extensive sources of help, including
-	tutorials, available at www.python.org/doc.  Selected URLs can be added
-	or removed from the Help menu at any time using Configure IDLE.
-
-Basic editing and navigation:
-
-	Backspace deletes char to the left; DEL deletes char to the right.
-	Control-backspace deletes word left, Control-DEL deletes word right.
-	Arrow keys and Page Up/Down move around.
-	Control-left/right Arrow moves by words in a strange but useful way.
-	Home/End go to begin/end of line.
-	Control-Home/End go to begin/end of file.
-	Some useful Emacs bindings are inherited from Tcl/Tk:
-		Control-a     beginning of line
-		Control-e     end of line
-		Control-k     kill line (but doesn't put it in clipboard)
-		Control-l     center window around the insertion point
-	Standard Windows bindings may work on that platform.
-	Keybindings are selected in the Settings Dialog, look there.
-
-Automatic indentation:
-
-	After a block-opening statement, the next line is indented by 4 spaces
-	(in the Python Shell window by one tab).  After certain keywords
-	(break, return etc.) the next line is dedented.  In leading
-	indentation, Backspace deletes up to 4 spaces if they are there.  Tab
-	inserts spaces (in the Python Shell window one tab), number depends on
-	Indent Width.  (N.B. Currently tabs are restricted to four spaces due
-	to Tcl/Tk issues.)
-
-        See also the indent/dedent region commands in the edit menu.
-
-Completions:
-
-	Completions are supplied for functions, classes, and attributes of
-	classes, both built-in and user-defined.  Completions are also provided
-	for filenames.
-
-	The AutoCompleteWindow (ACW) will open after a predefined delay
-	(default is two seconds) after a '.' or (in a string) an os.sep is
-	typed.  If after one of those characters (plus zero or more other
-	characters) you type a Tab the ACW will open immediately if a possible
-	continuation is found.
-
-	If there is only one possible completion for the characters entered, a
-	Tab will supply that completion without opening the ACW.
-
-	'Show Completions' will force open a completions window.  In an empty
-	string, this will contain the files in the current directory.  On a
-	blank line, it will contain the built-in and user-defined functions and
-	classes in the current name spaces, plus any modules imported.  If some
-	characters have been entered, the ACW will attempt to be more specific.
-
-	If string of characters is typed, the ACW selection will jump to the
-	entry most closely matching those characters. Entering a Tab will cause
-	the longest non-ambiguous match to be entered in the Edit window or
-	Shell.  Two Tabs in a row will supply the current ACW selection, as
-	will Return or a double click.  Cursor keys, Page Up/Down, mouse
-	selection, and the scrollwheel all operate on the ACW.
-
-	'Hidden' attributes can be accessed by typing the beginning of hidden
-	name after a '.'.  e.g. '_'.  This allows access to modules with
-	'__all__' set, or to class-private attributes.
-
-	Completions and the 'Expand Word' facility can save a lot of typing!
-
-	Completions are currently limited to those in the namespaces.  Names in
-	an Edit window which are not via __main__ or sys.modules will not be
-	found.  Run the module once with your imports to correct this
-	situation.  Note that IDLE itself places quite a few modules in
-	sys.modules, so much can be found by default, e.g. the re module.
-
-	If you don't like the ACW popping up unbidden, simply make the delay
-	longer or disable the extension.  OTOH, you could make the delay zero.
-
-	You could also switch off the CallTips extension.  (We will be adding
-	a delay to the call tip window.)
-
-Python Shell window:
-
-	Control-c interrupts executing command.
-	Control-d sends end-of-file; closes window if typed at >>> prompt.
-
-    Command history:
-
-	Alt-p retrieves previous command matching what you have typed.
-	Alt-n retrieves next.
-	      (These are Control-p, Control-n on OS X)
-	Return while cursor is on a previous command retrieves that command.
-	Expand word is also useful to reduce typing.
-
-    Syntax colors:
-
-	The coloring is applied in a background "thread", so you may
-	occasionally see uncolorized text.  To change the color
-	scheme, use the Configure IDLE / Highlighting dialog.
-
-    Python default syntax colors:
-
-	Keywords	orange
-	Builtins	royal purple
-	Strings		green
-	Comments	red
-	Definitions	blue
-
-    Shell default colors:
-
-	Console output	brown
-	stdout		blue
-	stderr		red
-	stdin		black
-
-Other preferences:
-
-	The font preferences, keybinding, and startup preferences can
-	be changed using the Settings dialog.
-
-Command line usage:
-
-	Enter idle -h at the command prompt to get a usage message.
-
-Running without a subprocess:
-
-	If IDLE is started with the -n command line switch it will run in a
-	single process and will not create the subprocess which runs the RPC
-	Python execution server.  This can be useful if Python cannot create
-	the subprocess or the RPC socket interface on your platform.  However,
-	in this mode user code is not isolated from IDLE itself.  Also, the
-	environment is not restarted when Run/Run Module (F5) is selected.  If
-	your code has been modified, you must reload() the affected modules and
-	re-import any specific items (e.g. from foo import baz) if the changes
-	are to take effect.  For these reasons, it is preferable to run IDLE
-	with the default subprocess if at all possible.
-
-Extensions:
-
-	IDLE contains an extension facility.  See the beginning of
-	config-extensions.def in the idlelib directory for further information.
-	The default extensions are currently:
-
-		FormatParagraph
-		AutoExpand
-		ZoomHeight
-		ScriptBinding
-		CallTips
-		ParenMatch
-		AutoComplete
-		CodeContext

-"""Import hook support.
-
-Consistent use of this module will make it possible to change the
-different mechanisms involved in loading modules independently.
-
-While the built-in module imp exports interfaces to the built-in
-module searching and loading algorithm, and it is possible to replace
-the built-in function __import__ in order to change the semantics of
-the import statement, until now it has been difficult to combine the
-effect of different __import__ hacks, like loading modules from URLs
-by rimport.py, or restricted execution by rexec.py.
-
-This module defines three new concepts:
-
-1) A "file system hooks" class provides an interface to a filesystem.
-
-One hooks class is defined (Hooks), which uses the interface provided
-by standard modules os and os.path.  It should be used as the base
-class for other hooks classes.
-
-2) A "module loader" class provides an interface to search for a
-module in a search path and to load it.  It defines a method which
-searches for a module in a single directory; by overriding this method
-one can redefine the details of the search.  If the directory is None,
-built-in and frozen modules are searched instead.
-
-Two module loader class are defined, both implementing the search
-strategy used by the built-in __import__ function: ModuleLoader uses
-the imp module's find_module interface, while HookableModuleLoader
-uses a file system hooks class to interact with the file system.  Both
-use the imp module's load_* interfaces to actually load the module.
-
-3) A "module importer" class provides an interface to import a
-module, as well as interfaces to reload and unload a module.  It also
-provides interfaces to install and uninstall itself instead of the
-default __import__ and reload (and unload) functions.
-
-One module importer class is defined (ModuleImporter), which uses a
-module loader instance passed in (by default HookableModuleLoader is
-instantiated).
-
-The classes defined here should be used as base classes for extended
-functionality along those lines.
-
-If a module importer class supports dotted names, its import_module()
-must return a different value depending on whether it is called on
-behalf of a "from ... import ..." statement or not.  (This is caused
-by the way the __import__ hook is used by the Python interpreter.)  It
-would also do wise to install a different version of reload().

-#   need __path__ processing
-#   performance
-#   move chaining to a subclass [gjs: it's been nuked]
-#   deinstall should be possible

-#     module->file location mapper to speed FS-based imports
-#     relative imports
-#     keep chaining so that it can play nice with other import hooks
-#
-# from Gordon:
-#   push MAL's mapper into sys.path[0] as a cache (hard-coded for apps)
-#
-# from Guido:
-#   need to change sys.* references for rexec environs
-#   need hook for MAL's walk-me-up import strategy, or Tim's absolute strategy
-#   watch out for sys.modules[...] is None
-#   flag to force absolute imports? (speeds _determine_import_context and
-#       checking for a relative module)
-#   insert names of archives into sys.path  (see quote below)
-#   note: reload does NOT blast module dict
-#   shift import mechanisms and policies around; provide for hooks, overrides
-#       (see quote below)
-#   add get_source stuff
-#   get_topcode and get_subcode
-#   CRLF handling in _compile
-#   race condition in _compile
-#   refactoring of os.py to deal with _os_bootstrap problem
-#   any special handling to do for importing a module with a SyntaxError?
-#       (e.g. clean up the traceback)
-#   implement "domain" for path-type functionality using pkg namespace
-#       (rather than FS-names like __path__)
-#   don't use the word "private"... maybe "internal"
-#
-#
-# Guido's comments on sys.path caching:
-#
-# We could cache this in a dictionary: the ImportManager can have a
-# cache dict mapping pathnames to importer objects, and a separate
-# method for coming up with an importer given a pathname that's not yet
-# in the cache.  The method should do a stat and/or look at the
-# extension to decide which importer class to use; you can register new
-# importer classes by registering a suffix or a Boolean function, plus a
-# class.  If you register a new importer class, the cache is zapped.
-# The cache is independent from sys.path (but maintained per
-# ImportManager instance) so that rearrangements of sys.path do the
-# right thing.  If a path is dropped from sys.path the corresponding
-# cache entry is simply no longer used.
-#
-# My/Guido's comments on factoring ImportManager and Importer:
-#
-# > However, we still have a tension occurring here:
-# >
-# > 1) implementing policy in ImportManager assists in single-point policy
-# >    changes for app/rexec situations
-# > 2) implementing policy in Importer assists in package-private policy
-# >    changes for normal, operating conditions
-# >
-# > I'll see if I can sort out a way to do this. Maybe the Importer class will
-# > implement the methods (which can be overridden to change policy) by
-# > delegating to ImportManager.
-#
-# Maybe also think about what kind of policies an Importer would be
-# likely to want to change.  I have a feeling that a lot of the code
-# there is actually not so much policy but a *necessity* to get things
-# working given the calling conventions for the __import__ hook: whether
-# to return the head or tail of a dotted name, or when to do the "finish
-# fromlist" stuff.

-r"""JSON (JavaScript Object Notation) <http://json.org> is a subset of
-JavaScript syntax (ECMA-262 3rd edition) used as a lightweight data
-interchange format.
-
-:mod:`json` exposes an API familiar to users of the standard library
-:mod:`marshal` and :mod:`pickle` modules. It is the externally maintained
-version of the :mod:`json` library contained in Python 2.6, but maintains
-compatibility with Python 2.4 and Python 2.5 and (currently) has
-significant performance advantages, even without using the optional C
-extension for speedups.
-
-Encoding basic Python object hierarchies::
-
-    >>> import json
-    >>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
-    '["foo", {"bar": ["baz", null, 1.0, 2]}]'
-    >>> print json.dumps("\"foo\bar")
-    "\"foo\bar"
-    >>> print json.dumps(u'\u1234')
-    "\u1234"
-    >>> print json.dumps('\\')
-    "\\"
-    >>> print json.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True)

-    >>> from StringIO import StringIO
-    >>> io = StringIO()
-    >>> json.dump(['streaming API'], io)
-    >>> io.getvalue()
-    '["streaming API"]'
-
-Compact encoding::
-
-    >>> import json
-    >>> json.dumps([1,2,3,{'4': 5, '6': 7}], sort_keys=True, separators=(',',':'))
-    '[1,2,3,{"4":5,"6":7}]'
-
-Pretty printing::
-
-    >>> import json
-    >>> print json.dumps({'4': 5, '6': 7}, sort_keys=True,
-    ...                  indent=4, separators=(',', ': '))
-    {
-        "4": 5,
-        "6": 7
-    }
-
-Decoding JSON::
-
-    >>> import json
-    >>> obj = [u'foo', {u'bar': [u'baz', None, 1.0, 2]}]
-    >>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]') == obj
-    True
-    >>> json.loads('"\\"foo\\bar"') == u'"foo\x08ar'
-    True
-    >>> from StringIO import StringIO
-    >>> io = StringIO('["streaming API"]')
-    >>> json.load(io)[0] == 'streaming API'
-    True
-
-Specializing JSON object decoding::
-
-    >>> import json
-    >>> def as_complex(dct):
-    ...     if '__complex__' in dct:
-    ...         return complex(dct['real'], dct['imag'])
-    ...     return dct
-    ...
-    >>> json.loads('{"__complex__": true, "real": 1, "imag": 2}',
-    ...     object_hook=as_complex)
-    (1+2j)
-    >>> from decimal import Decimal
-    >>> json.loads('1.1', parse_float=Decimal) == Decimal('1.1')
-    True
-
-Specializing JSON object encoding::
-
-    >>> import json
-    >>> def encode_complex(obj):
-    ...     if isinstance(obj, complex):
-    ...         return [obj.real, obj.imag]

-        If *ensure_ascii* is true (the default), all non-ASCII
-        characters in the output are escaped with \uXXXX sequences,
-        and the results are str instances consisting of ASCII
-        characters only.  If ensure_ascii is False, a result may be a
-        unicode instance.  This usually happens if the input contains
-        unicode strings or the *encoding* parameter is used.
-
-        If check_circular is true, then lists, dicts, and custom encoded
-        objects will be checked for circular references during encoding to
-        prevent an infinite recursion (which would cause an OverflowError).
-        Otherwise, no such check takes place.
-
-        If allow_nan is true, then NaN, Infinity, and -Infinity will be
-        encoded as such.  This behavior is not JSON specification compliant,
-        but is consistent with most JavaScript based encoders and decoders.
-        Otherwise, it will be a ValueError to encode such floats.
-
-        If sort_keys is true, then the output of dictionaries will be
-        sorted by key; this is useful for regression tests to ensure
-        that JSON serializations can be compared on a day-to-day basis.
-
-        If indent is a non-negative integer, then JSON array
-        elements and object members will be pretty-printed with that
-        indent level.  An indent level of 0 will only insert newlines.
-        None is the most compact representation.  Since the default
-        item separator is ', ',  the output might include trailing
-        whitespace when indent is specified.  You can use
-        separators=(',', ': ') to avoid this.
-
-        If specified, separators should be a (item_separator, key_separator)
-        tuple.  The default is (', ', ': ').  To get the most compact JSON
-        representation you should specify (',', ':') to eliminate whitespace.
-
-        If specified, default is a function that gets called for objects
-        that can't otherwise be serialized.  It should return a JSON encodable
-        version of the object or raise a ``TypeError``.
-
-        If encoding is not None, then all input strings will be
-        transformed into unicode using that encoding prior to JSON-encoding.
-        The default is UTF-8.

-Metadata-Version: 1.1
-Name: Python
-Version: 2.7.6
-Summary: A high-level object-oriented programming language
-Home-page: http://www.python.org/2.7
-Author: Guido van Rossum and the Python community
-Author-email: python-dev@python.org
-License: PSF license
-Description: Python is an interpreted, interactive, object-oriented programming
-        language. It is often compared to Tcl, Perl, Scheme or Java.
-        
-        Python combines remarkable power with very clear syntax. It has
-        modules, classes, exceptions, very high level dynamic data types, and
-        dynamic typing. There are interfaces to many system calls and
-        libraries, as well as to various windowing systems (X11, Motif, Tk,
-        Mac, MFC). New built-in modules are easily written in C or C++. Python
-        is also usable as an extension language for applications that need a
-        programmable interface.
-        
-        The Python implementation is portable: it runs on many brands of UNIX,
-        on Windows, DOS, OS/2, Mac, Amiga... If your favorite system isn't
-        listed here, it may still be supported, if there's a C compiler for
-        it. Ask around on comp.lang.python -- or just try compiling Python
-        yourself.

-"""Drag-and-drop support for Tkinter.
-
-This is very preliminary.  I currently only support dnd *within* one
-application, between different windows (or within the same window).
-
-I an trying to make this as generic as possible -- not dependent on
-the use of a particular widget or icon type, etc.  I also hope that
-this will work with Pmw.
-
-To enable an object to be dragged, you must create an event binding
-for it that starts the drag-and-drop process. Typically, you should
-bind <ButtonPress> to a callback function that you write. The function
-should call Tkdnd.dnd_start(source, event), where 'source' is the
-object to be dragged, and 'event' is the event that invoked the call
-(the argument to your callback function).  Even though this is a class
-instantiation, the returned instance should not be stored -- it will
-be kept alive automatically for the duration of the drag-and-drop.
-
-When a drag-and-drop is already in process for the Tk interpreter, the
-call is *ignored*; this normally averts starting multiple simultaneous
-dnd processes, e.g. because different button callbacks all
-dnd_start().
-
-The object is *not* necessarily a widget -- it can be any
-application-specific object that is meaningful to potential
-drag-and-drop targets.
-
-Potential drag-and-drop targets are discovered as follows.  Whenever
-the mouse moves, and at the start and end of a drag-and-drop move, the
-Tk widget directly under the mouse is inspected.  This is the target
-widget (not to be confused with the target object, yet to be
-determined).  If there is no target widget, there is no dnd target
-object.  If there is a target widget, and it has an attribute
-dnd_accept, this should be a function (or any callable object).  The
-function is called as dnd_accept(source, event), where 'source' is the
-object being dragged (the object passed to dnd_start() above), and
-'event' is the most recent event object (generally a <Motion> event;
-it can also be <ButtonPress> or <ButtonRelease>).  If the dnd_accept()
-function returns something other than None, this is the new dnd target
-object.  If dnd_accept() returns None, or if the target widget has no
-dnd_accept attribute, the target widget's parent is considered as the
-target widget, and the search for a target object is repeated from
-there.  If necessary, the search is repeated all the way up to the
-root widget.  If none of the target widgets can produce a target
-object, there is no target object (the target object is None).
-
-The target object thus produced, if any, is called the new target
-object.  It is compared with the old target object (or None, if there
-was no old target widget).  There are several cases ('source' is the
-source object, and 'event' is the most recent event object):
-
-- Both the old and new target objects are None.  Nothing happens.
-
-- The old and new target objects are the same object.  Its method
-dnd_motion(source, event) is called.
-
-- The old target object was None, and the new target object is not
-None.  The new target object's method dnd_enter(source, event) is
-called.
-
-- The new target object is None, and the old target object is not
-None.  The old target object's method dnd_leave(source, event) is
-called.
-
-- The old and new target objects differ and neither is None.  The old
-target object's method dnd_leave(source, event), and then the new
-target object's method dnd_enter(source, event) is called.
-
-Once this is done, the new target object replaces the old one, and the
-Tk mainloop proceeds.  The return value of the methods mentioned above
-is ignored; if they raise an exception, the normal exception handling
-mechanisms take over.
-
-The drag-and-drop processes can end in two ways: a final target object
-is selected, or no final target object is selected.  When a final
-target object is selected, it will always have been notified of the
-potential drop by a call to its dnd_enter() method, as described
-above, and possibly one or more calls to its dnd_motion() method; its
-dnd_leave() method has not been called since the last call to
-dnd_enter().  The target is notified of the drop by a call to its
-method dnd_commit(source, event).
-
-If no final target object is selected, and there was an old target
-object, its dnd_leave(source, event) method is called to complete the
-dnd sequence.
-
-Finally, the source object is notified that the drag-and-drop process
-is over, by a call to source.dnd_end(target, event), specifying either
-the selected target object, or None if no target object was selected.
-The source object can use this to implement the commit action; this is
-sometimes simpler than to do it in the target's dnd_commit().  The
-target's dnd_commit() method could then simply be aliased to
-dnd_leave().
-
-At any time during a dnd sequence, the application can cancel the
-sequence by calling the cancel() method on the object returned by
-dnd_start().  This will call dnd_leave() if a target is currently
-active; it will never call dnd_commit().

-"""Wrapper functions for Tcl/Tk.
-
-Tkinter provides classes which allow the display, positioning and
-control of widgets. Toplevel widgets are Tk and Toplevel. Other
-widgets are Frame, Label, Entry, Text, Canvas, Button, Radiobutton,
-Checkbutton, Scale, Listbox, Scrollbar, OptionMenu, Spinbox
-LabelFrame and PanedWindow.
-
-Properties of the widgets are specified with keyword arguments.
-Keyword arguments have the same name as the corresponding resource
-under Tk.
-
-Widgets are positioned with one of the geometry managers Place, Pack
-or Grid. These managers can be called with methods place, pack, grid
-available in every Widget.
-
-Actions are bound to events by resources (e.g. keyword argument
-command) or with the method bind.
-
-Example (Hello, World):
-import Tkinter

-tk = Tkinter.Tk()
-frame = Tkinter.Frame(tk, relief=RIDGE, borderwidth=2)

-label = Tkinter.Label(frame, text="Hello, World")

-            should be the name of a window already managed by pathName.
-        height size
-            Specify a height for the window. The height will be the
-            outer dimension of the window including its border, if
-            any. If size is an empty string, or if -height is not
-            specified, then the height requested internally by the
-            window will be used initially; the height may later be
-            adjusted by the movement of sashes in the panedwindow.
-            Size may be any value accepted by Tk_GetPixels.
-        minsize n
-            Specifies that the size of the window cannot be made
-            less than n. This constraint only affects the size of
-            the widget in the paned dimension -- the x dimension
-            for horizontal panedwindows, the y dimension for
-            vertical panedwindows. May be any value accepted by
-            Tk_GetPixels.
-        padx n
-            Specifies a non-negative value indicating how much
-            extra space to leave on each side of the window in
-            the X-direction. The value may have any of the forms
-            accepted by Tk_GetPixels.
-        pady n
-            Specifies a non-negative value indicating how much
-            extra space to leave on each side of the window in
-            the Y-direction. The value may have any of the forms
-            accepted by Tk_GetPixels.
-        sticky style
-            If a window's pane is larger than the requested
-            dimensions of the window, this option may be used
-            to position (or stretch) the window within its pane.
-            Style is a string that contains zero or more of the
-            characters n, s, e or w. The string can optionally
-            contains spaces or commas, but they are ignored. Each
-            letter refers to a side (north, south, east, or west)
-            that the window will "stick" to. If both n and s
-            (or e and w) are specified, the window will be
-            stretched to fill the entire height (or width) of
-            its cavity.
-        width size
-            Specify a width for the window. The width will be
-            the outer dimension of the window including its
-            border, if any. If size is an empty string, or
-            if -width is not specified, then the width requested
-            internally by the window will be used initially; the
-            width may later be adjusted by the movement of sashes
-            in the panedwindow. Size may be any value accepted by
-            Tk_GetPixels.

-generate_tokens(readline) is a generator that breaks a stream of
-text into Python tokens.  It accepts a readline-like method which is called
-repeatedly to get the next line of input (or "" for EOF).  It generates
-5-tuples with these members:
-
-    the token type (see token.py)
-    the token (a string)
-    the starting (row, column) indices of the token (a 2-tuple of ints)
-    the ending (row, column) indices of the token (a 2-tuple of ints)
-    the original line (string)
-
-It is designed to match the working of the Python tokenizer exactly, except
-that it produces COMMENT tokens for comments and gives type OP for all
-operators
-
-Older entry points
-    tokenize_loop(readline, tokeneater)
-    tokenize(readline, tokeneater=printtoken)
-are the same, except instead of generating tokens, tokeneater is a callback
-function to which the 5 fields described above are passed as 5 arguments,
-each time a new token is found."""

-    The generate_tokens() generator requires one argment, readline, which

-    column where the token begins in the source; a 2-tuple (erow, ecol) of
-    ints specifying the row and column where the token ends in the source;

-""" Locale support.
-
-    The module provides low-level access to the C lib's locale APIs
-    and adds high level number formatting APIs as well as a locale
-    aliasing engine to complement these.
-
-    The aliasing engine includes support for many commonly used locale
-    names and maps them to values suitable for passing to the C lib's
-    setlocale() function. It also includes default encodings for all
-    supported locale names.

-
-    Formatters need to know how a LogRecord is constructed. They are
-    responsible for converting a LogRecord to (usually) a string which can
-    be interpreted by either a human or an external system. The base Formatter
-    allows a formatting string to be specified. If none is supplied, the
-    default value of "%s(message)\\n" is used.
-
-    The Formatter can be initialized with a format string which makes use of
-    knowledge of the LogRecord attributes - e.g. the default value mentioned
-    above makes use of the fact that the user's message and arguments are pre-
-    formatted into a LogRecord's message attribute. Currently, the useful
-    attributes in a LogRecord are described by:
-
-    %(name)s            Name of the logger (logging channel)
-    %(levelno)s         Numeric logging level for the message (DEBUG, INFO,
-                        WARNING, ERROR, CRITICAL)
-    %(levelname)s       Text logging level for the message ("DEBUG", "INFO",
-                        "WARNING", "ERROR", "CRITICAL")
-    %(pathname)s        Full pathname of the source file where the logging
-                        call was issued (if available)
-    %(filename)s        Filename portion of pathname
-    %(module)s          Module (name portion of filename)
-    %(lineno)d          Source line number where the logging call was issued
-                        (if available)

-    %(relativeCreated)d Time in milliseconds when the LogRecord was created,

-"""A readline()-style interface to the parts of a multipart message.
-
-The MultiFile class makes each part of a multipart message "feel" like
-an ordinary file, as long as you use fp.readline().  Allows recursive
-use, for nested multipart messages.  Probably best used together
-with module mimetools.
-
-Suggested use:
-
-real_fp = open(...)
-fp = MultiFile(real_fp)
-
-"read some lines from fp"
-fp.push(separator)
-while 1:
-        "read lines from fp until it returns an empty string" (A)
-        if not fp.next(): break
-fp.pop()
-"read remaining lines from fp until it returns an empty string"
-
-The latter sequence may be used recursively at (A).
-It is also allowed to use multiple push()...pop() sequences.
-
-If seekable is given as 0, the class code will not do the bookkeeping
-it normally attempts in order to make seeks relative to the beginning of the
-current file part.  This may be useful when using MultiFile with a non-
-seekable stream object.

-    """Directory tree generator.
-
-    For each directory in the directory tree rooted at top (including top
-    itself, but excluding '.' and '..'), yields a 3-tuple
-
-        dirpath, dirnames, filenames
-
-    dirpath is a string, the path to the directory.  dirnames is a list of
-    the names of the subdirectories in dirpath (excluding '.' and '..').
-    filenames is a list of the names of the non-directory files in dirpath.
-    Note that the names in the lists are just names, with no path components.
-    To get a full path (which begins with top) to a file or directory in
-    dirpath, do os.path.join(dirpath, name).
-
-    If optional arg 'topdown' is true or not specified, the triple for a
-    directory is generated before the triples for any of its subdirectories
-    (directories are generated top down).  If topdown is false, the triple
-    for a directory is generated after the triples for all of its
-    subdirectories (directories are generated bottom up).
-
-    When topdown is true, the caller can modify the dirnames list in-place
-    (e.g., via del or slice assignment), and walk will only recurse into the
-    subdirectories whose names remain in dirnames; this can be used to prune
-    the search, or to impose a specific order of visiting.  Modifying
-    dirnames when topdown is false is ineffective, since the directories in
-    dirnames have already been generated by the time dirnames itself is
-    generated.
-
-    By default errors from the os.listdir() call are ignored.  If
-    optional arg 'onerror' is specified, it should be a function; it
-    will be called with one argument, an os.error instance.  It can
-    report the error to continue with the walk, or raise the exception
-    to abort the walk.  Note that the filename is available as the
-    filename attribute of the exception object.
-
-    By default, os.walk does not follow symbolic links to subdirectories on
-    systems that support them.  In order to get this functionality, set the
-    optional argument 'followlinks' to true.
-
-    Caution:  if you pass a relative pathname for top, don't change the
-    current working directory between resumptions of walk.  walk never
-    changes the current directory, and assumes that the client doesn't
-    either.
-
-    Example:
-
-    import os
-    from os.path import join, getsize
-    for root, dirs, files in os.walk('python/Lib/email'):
-        print root, "consumes",
-        print sum([getsize(join(root, name)) for name in files]),
-        print "bytes in", len(files), "non-directory files"

-The Python Debugger Pdb
-=======================
-
-To use the debugger in its simplest form:
-
-        >>> import pdb
-        >>> pdb.run('<a statement>')
-
-The debugger's prompt is '(Pdb) '.  This will stop in the first
-function call in <a statement>.
-
-Alternatively, if a statement terminated with an unhandled exception,
-you can use pdb's post-mortem facility to inspect the contents of the
-traceback:
-
-        >>> <a statement>
-        <exception traceback>
-        >>> import pdb
-        >>> pdb.pm()
-
-The commands recognized by the debugger are listed in the next
-section.  Most can be abbreviated as indicated; e.g., h(elp) means
-that 'help' can be typed as 'h' or 'help' (but not as 'he' or 'hel',
-nor as 'H' or 'Help' or 'HELP').  Optional arguments are enclosed in
-square brackets.
-
-A blank line repeats the previous command literally, except for
-'list', where it lists the next 11 lines.
-
-Commands that the debugger doesn't recognize are assumed to be Python
-statements and are executed in the context of the program being
-debugged.  Python statements can also be prefixed with an exclamation
-point ('!').  This is a powerful way to inspect the program being
-debugged; it is even possible to change variables.  When an exception
-occurs in such a statement, the exception name is printed but the
-debugger's state is not changed.
-
-The debugger supports aliases, which can save typing.  And aliases can
-have parameters (see the alias help entry) which allows one a certain
-level of adaptability to the context under examination.
-
-Multiple commands may be entered on a single line, separated by the
-pair ';;'.  No intelligence is applied to separating the commands; the
-input is split at the first ';;', even if it is in the middle of a
-quoted string.
-
-If a file ".pdbrc" exists in your home directory or in the current
-directory, it is read in and executed as if it had been typed at the
-debugger prompt.  This is particularly useful for aliases.  If both
-files exist, the one in the home directory is read first and aliases
-defined there can be overriden by the local file.
-
-Aside from aliases, the debugger is not directly programmable; but it
-is implemented as a class from which you can derive your own debugger
-class, which you can make as fancy as you like.
-
-
-Debugger commands
-=================
-
-h(elp)
-        Without argument, print the list of available commands.  With
-        a command name as argument, print help about that command
-        (this is currently not implemented).
-
-w(here)
-        Print a stack trace, with the most recent frame at the bottom.
-        An arrow indicates the "current frame", which determines the
-        context of most commands.
-
-d(own)
-        Move the current frame one level down in the stack trace
-        (to a newer frame).
-
-u(p)
-        Move the current frame one level up in the stack trace
-        (to an older frame).
-
-b(reak) [ ([filename:]lineno | function) [, condition] ]
-        With a filename:line number argument, set a break there.  If
-        filename is omitted, use the current file.  With a function
-        name, set a break at the first executable line of that
-        function.  Without argument, list all breaks.  Each breakpoint
-        is assigned a number to which all the other breakpoint
-        commands refer.
-
-        The condition argument, if present, is a string which must
-        evaluate to true in order for the breakpoint to be honored.
-
-tbreak [ ([filename:]lineno | function) [, condition] ]
-        Temporary breakpoint, which is removed automatically when it
-        is first hit.  The arguments are the same as break.
-
-cl(ear) [bpnumber [bpnumber ...] ]
-        With a space separated list of breakpoint numbers, clear those
-        breakpoints.  Without argument, clear all breaks (but first
-        ask confirmation).
-
-disable bpnumber [bpnumber ...]
-        Disables the breakpoints given as a space separated list of
-        breakpoint numbers.  Disabling a breakpoint means it cannot
-        cause the program to stop execution, but unlike clearing a
-        breakpoint, it remains in the list of breakpoints and can be
-        (re-)enabled.
-
-enable bpnumber [bpnumber ...]
-        Enables the breakpoints specified.
-
-ignore bpnumber count
-        Sets the ignore count for the given breakpoint number.  If
-        count is omitted, the ignore count is set to 0.  A breakpoint
-        becomes active when the ignore count is zero.  When non-zero,
-        the count is decremented each time the breakpoint is reached
-        and the breakpoint is not disabled and any associated
-        condition evaluates to true.
-
-condition bpnumber condition
-        condition is an expression which must evaluate to true before
-        the breakpoint is honored.  If condition is absent, any
-        existing condition is removed; i.e., the breakpoint is made
-        unconditional.
-
-s(tep)
-        Execute the current line, stop at the first possible occasion
-        (either in a function that is called or in the current function).
-
-n(ext)
-        Continue execution until the next line in the current function
-        is reached or it returns.
-
-unt(il)
-        Continue execution until the line with a number greater than the 
-        current one is reached or until the current frame returns.
-
-r(eturn)
-        Continue execution until the current function returns.
-
-run [args...]
-        Restart the debugged python program. If a string is supplied it is
-        splitted with "shlex", and the result is used as the new sys.argv.
-        History, breakpoints, actions and debugger options are preserved.
-        "restart" is an alias for "run".
-
-c(ont(inue))
-        Continue execution, only stop when a breakpoint is encountered.
-
-l(ist) [first [,last]]
-        List source code for the current file.
-        Without arguments, list 11 lines around the current line
-        or continue the previous listing.
-        With one argument, list 11 lines starting at that line.
-        With two arguments, list the given range;
-        if the second argument is less than the first, it is a count.
-
-a(rgs)
-        Print the argument list of the current function.
-
-p expression
-        Print the value of the expression.
-
-(!) statement
-        Execute the (one-line) statement in the context of the current
-        stack frame.  The exclamation point can be omitted unless the
-        first word of the statement resembles a debugger command.  To
-        assign to a global variable you must always prefix the command
-        with a 'global' command, e.g.:
-        (Pdb) global list_options; list_options = ['-l']
-        (Pdb)
-
-
-whatis arg
-         Prints the type of the argument.
-
-alias [name [command]]
-        Creates an alias called 'name' that executes 'command'.  The
-        command must *not* be enclosed in quotes.  Replaceable
-        parameters can be indicated by %1, %2, and so on, while %* is
-        replaced by all the parameters.  If no command is given, the
-        current alias for name is shown. If no name is given, all
-        aliases are listed.
-
-        Aliases may be nested and can contain anything that can be
-        legally typed at the pdb prompt.  Note!  You *can* override
-        internal pdb commands with aliases!  Those internal commands
-        are then hidden until the alias is removed.  Aliasing is
-        recursively applied to the first word of the command line; all
-        other words in the line are left alone.
-
-        As an example, here are two useful aliases (especially when
-        placed in the .pdbrc file):
-
-        #Print instance variables (usage "pi classInst")
-        alias pi for k in %1.__dict__.keys(): print "%1.",k,"=",%1.__dict__[k]
-        #Print instance variables in self
-        alias ps pi self
-                
-unalias name
-        Deletes the specified alias.
-
-q(uit)
-        Quit from the debugger.
-        The program being executed is aborted.

-
-genops(pickle)
-   Generate all the opcodes in a pickle, as (opcode, arg, position) triples.
-
-dis(pickle, out=None, memo=None, indentlevel=4)
-   Print a symbolic disassembly of a pickle.
-'''
-
-__all__ = ['dis', 'genops', 'optimize']
-
-# Other ideas:
-#
-# - A pickle verifier:  read a pickle and check it exhaustively for
-#   well-formedness.  dis() does a lot of this already.
-#
-# - A protocol identifier:  examine a pickle and return its protocol number
-#   (== the highest .proto attr value among all the opcodes in the pickle).
-#   dis() already prints this info at the end.
-#
-# - A pickle optimizer:  for example, tuple-building code is sometimes more
-#   elaborate than necessary, catering for the possibility that the tuple
-#   is recursive.  Or lots of times a PUT is generated that's never accessed
-#   by a later GET.
-
-
-"""
-"A pickle" is a program for a virtual pickle machine (PM, but more accurately
-called an unpickling machine).  It's a sequence of opcodes, interpreted by the
-PM, building an arbitrarily complex Python object.
-
-For the most part, the PM is very simple:  there are no looping, testing, or
-conditional instructions, no arithmetic and no function calls.  Opcodes are
-executed once each, from first to last, until a STOP opcode is reached.
-
-The PM has two data areas, "the stack" and "the memo".
-
-Many opcodes push Python objects onto the stack; e.g., INT pushes a Python
-integer object on the stack, whose value is gotten from a decimal string
-literal immediately following the INT opcode in the pickle bytestream.  Other
-opcodes take Python objects off the stack.  The result of unpickling is
-whatever object is left on the stack when the final STOP opcode is executed.
-
-The memo is simply an array of objects, or it can be implemented as a dict
-mapping little integers to objects.  The memo serves as the PM's "long term
-memory", and the little integers indexing the memo are akin to variable
-names.  Some opcodes pop a stack object into the memo at a given index,
-and others push a memo object at a given index onto the stack again.
-
-At heart, that's all the PM has.  Subtleties arise for these reasons:
-
-+ Object identity.  Objects can be arbitrarily complex, and subobjects
-  may be shared (for example, the list [a, a] refers to the same object a
-  twice).  It can be vital that unpickling recreate an isomorphic object
-  graph, faithfully reproducing sharing.
-
-+ Recursive objects.  For example, after "L = []; L.append(L)", L is a
-  list, and L[0] is the same list.  This is related to the object identity
-  point, and some sequences of pickle opcodes are subtle in order to
-  get the right result in all cases.
-
-+ Things pickle doesn't know everything about.  Examples of things pickle
-  does know everything about are Python's builtin scalar and container
-  types, like ints and tuples.  They generally have opcodes dedicated to
-  them.  For things like module references and instances of user-defined
-  classes, pickle's knowledge is limited.  Historically, many enhancements
-  have been made to the pickle protocol in order to do a better (faster,
-  and/or more compact) job on those.
-
-+ Backward compatibility and micro-optimization.  As explained below,
-  pickle opcodes never go away, not even when better ways to do a thing
-  get invented.  The repertoire of the PM just keeps growing over time.
-  For example, protocol 0 had two opcodes for building Python integers (INT
-  and LONG), protocol 1 added three more for more-efficient pickling of short
-  integers, and protocol 2 added two more for more-efficient pickling of
-  long integers (before protocol 2, the only ways to pickle a Python long
-  took time quadratic in the number of digits, for both pickling and
-  unpickling).  "Opcode bloat" isn't so much a subtlety as a source of
-  wearying complication.
-
-
-Pickle protocols:
-
-For compatibility, the meaning of a pickle opcode never changes.  Instead new
-pickle opcodes get added, and each version's unpickler can handle all the
-pickle opcodes in all protocol versions to date.  So old pickles continue to
-be readable forever.  The pickler can generally be told to restrict itself to
-the subset of opcodes available under previous protocol versions too, so that
-users can create pickles under the current version readable by older
-versions.  However, a pickle does not contain its version number embedded
-within it.  If an older unpickler tries to read a pickle using a later
-protocol, the result is most likely an exception due to seeing an unknown (in
-the older unpickler) opcode.
-
-The original pickle used what's now called "protocol 0", and what was called
-"text mode" before Python 2.3.  The entire pickle bytestream is made up of
-printable 7-bit ASCII characters, plus the newline character, in protocol 0.
-That's why it was called text mode.  Protocol 0 is small and elegant, but
-sometimes painfully inefficient.
-
-The second major set of additions is now called "protocol 1", and was called
-"binary mode" before Python 2.3.  This added many opcodes with arguments
-consisting of arbitrary bytes, including NUL bytes and unprintable "high bit"
-bytes.  Binary mode pickles can be substantially smaller than equivalent
-text mode pickles, and sometimes faster too; e.g., BININT represents a 4-byte
-int as 4 bytes following the opcode, which is cheaper to unpickle than the
-(perhaps) 11-character decimal string attached to INT.  Protocol 1 also added
-a number of opcodes that operate on many stack elements at once (like APPENDS
-and SETITEMS), and "shortcut" opcodes (like EMPTY_DICT and EMPTY_TUPLE).
-
-The third major set of additions came in Python 2.3, and is called "protocol
-2".  This added:
-
-- A better way to pickle instances of new-style classes (NEWOBJ).
-
-- A way for a pickle to identify its protocol (PROTO).
-
-- Time- and space- efficient pickling of long ints (LONG{1,4}).
-
-- Shortcuts for small tuples (TUPLE{1,2,3}}.
-
-- Dedicated opcodes for bools (NEWTRUE, NEWFALSE).
-
-- The "extension registry", a vector of popular objects that can be pushed
-  efficiently by index (EXT{1,2,4}).  This is akin to the memo and GET, but
-  the registry contents are predefined (there's nothing akin to the memo's
-  PUT).
-
-Another independent change with Python 2.3 is the abandonment of any
-pretense that it might be safe to load pickles received from untrusted
-parties -- no sufficient security analysis has been done to guarantee
-this and there isn't a use case that warrants the expense of such an
-analysis.
-
-To this end, all tests for __safe_for_unpickling__ or for
-copy_reg.safe_constructors are removed from the unpickling code.
-References to these variables in the descriptions below are to be seen
-as describing unpickling in Python 2.2 and before.

-bundlebuilder.py -- Tools to assemble MacOS X (application) bundles.
-
-This module contains two classes to build so called "bundles" for
-MacOS X. BundleBuilder is a general tool, AppBuilder is a subclass
-specialized in building application bundles.
-
-[Bundle|App]Builder objects are instantiated with a bunch of keyword
-arguments, and have a build() method that will do all the work. See
-the class doc strings for a description of the constructor arguments.
-
-The module contains a main program that can be used in two ways:
-
-  % python bundlebuilder.py [options] build
-  % python buildapp.py [options] build
-
-Where "buildapp.py" is a user-supplied setup.py-like script following
-this model:
-
-  from bundlebuilder import buildapp
-  buildapp(<lots-of-keyword-args>)

-"""Utility routines depending on the finder,
-a combination of code by Jack Jansen and erik@letterror.com.
-
-Most events have been captured from
-Lasso Capture AE and than translated to python code.
-
-IMPORTANT
-Note that the processes() function returns different values
-depending on the OS version it is running on. On MacOS 9
-the Finder returns the process *names* which can then be
-used to find out more about them. On MacOS 8.6 and earlier
-the Finder returns a code which does not seem to work.
-So bottom line: the processes() stuff does not work on < MacOS9
-
-Mostly written by erik@letterror.com

-"""icopen patch
-
-OVERVIEW
-
-icopen patches MacOS Python to use the Internet Config file mappings to select
-the type and creator for a file.
-
-Version 1 released to the public domain 3 November 1999
-by Oliver Steele (steele@cs.brandeis.edu).
-
-DETAILS
-
-This patch causes files created by Python's open(filename, 'w') command (and
-by functions and scripts that call it) to set the type and creator of the file
-to the type and creator associated with filename's extension (the
-portion of the filename after the last period), according to Internet Config.
-Thus, a script that creates a file foo.html will create one that opens in whatever
-browser you've set to handle *.html files, and so on.
-
-Python IDE uses its own algorithm to select the type and creator for saved
-editor windows, so this patch won't effect their types.
-
-As of System 8.6 at least, Internet Config is built into the system, and the
-file mappings are accessed from the Advanced pane of the Internet control
-panel.  User Mode (in the Edit menu) needs to be set to Advanced in order to
-access this pane.
-
-INSTALLATION
-
-Put this file in your Python path, and create a file named {Python}:sitecustomize.py
-that contains:
-        import icopen
-
-(If {Python}:sitecustomizer.py already exists, just add the 'import' line to it.)
-
-The next time you launch PythonInterpreter or Python IDE, the patch will take
-effect.

-#    History:
-#
-#    <see CVS and SVN checkin messages for history>
-#
-#    1.0.7 - added DEV_NULL
-#    1.0.6 - added linux_distribution()
-#    1.0.5 - fixed Java support to allow running the module on Jython
-#    1.0.4 - added IronPython support
-#    1.0.3 - added normalization of Windows system name
-#    1.0.2 - added more Windows support
-#    1.0.1 - reformatted to make doc.py happy
-#    1.0.0 - reformatted a bit and checked into Python CVS
-#    0.8.0 - added sys.version parser and various new access
-#            APIs (python_version(), python_compiler(), etc.)
-#    0.7.2 - fixed architecture() to use sizeof(pointer) where available
-#    0.7.1 - added support for Caldera OpenLinux
-#    0.7.0 - some fixes for WinCE; untabified the source file
-#    0.6.2 - support for OpenVMS - requires version 1.5.2-V006 or higher and
-#            vms_lib.getsyi() configured
-#    0.6.1 - added code to prevent 'uname -p' on platforms which are
-#            known not to support it
-#    0.6.0 - fixed win32_ver() to hopefully work on Win95,98,NT and Win2k;
-#            did some cleanup of the interfaces - some APIs have changed
-#    0.5.5 - fixed another type in the MacOS code... should have
-#            used more coffee today ;-)
-#    0.5.4 - fixed a few typos in the MacOS code
-#    0.5.3 - added experimental MacOS support; added better popen()
-#            workarounds in _syscmd_ver() -- still not 100% elegant
-#            though
-#    0.5.2 - fixed uname() to return '' instead of 'unknown' in all
-#            return values (the system uname command tends to return
-#            'unknown' instead of just leaving the field emtpy)
-#    0.5.1 - included code for slackware dist; added exception handlers
-#            to cover up situations where platforms don't have os.popen
-#            (e.g. Mac) or fail on socket.gethostname(); fixed libc
-#            detection RE
-#    0.5.0 - changed the API names referring to system commands to *syscmd*;
-#            added java_ver(); made syscmd_ver() a private
-#            API (was system_ver() in previous versions) -- use uname()
-#            instead; extended the win32_ver() to also return processor
-#            type information
-#    0.4.0 - added win32_ver() and modified the platform() output for WinXX
-#    0.3.4 - fixed a bug in _follow_symlinks()
-#    0.3.3 - fixed popen() and "file" command invokation bugs
-#    0.3.2 - added architecture() API and support for it in platform()
-#    0.3.1 - fixed syscmd_ver() RE to support Windows NT
-#    0.3.0 - added system alias support
-#    0.2.3 - removed 'wince' again... oh well.
-#    0.2.2 - added 'wince' to syscmd_ver() supported platforms
-#    0.2.1 - added cache logic and changed the platform string format
-#    0.2.0 - changed the API to use functions instead of module globals
-#            since some action take too long to be run on module import
-#    0.1.0 - first release

-r"""plistlib.py -- a tool to generate and parse MacOSX .plist files.
-
-The PropertyList (.plist) file format is a simple XML pickle supporting
-basic object types, like dictionaries, lists, numbers and strings.
-Usually the top level object is a dictionary.
-
-To write out a plist file, use the writePlist(rootObject, pathOrFile)
-function. 'rootObject' is the top level object, 'pathOrFile' is a
-filename or a (writable) file object.
-
-To parse a plist from a file, use the readPlist(pathOrFile) function,
-with a file name or a (readable) file object as the only argument. It
-returns the top level object (again, usually a dictionary).
-
-To work with plist data in strings, you can use readPlistFromString()
-and writePlistToString().
-
-Values can be strings, integers, floats, booleans, tuples, lists,
-dictionaries, Data or datetime.datetime objects. String values (including
-dictionary keys) may be unicode strings -- they will be written out as
-UTF-8.
-
-The <data> plist type is supported through the Data class. This is a
-thin wrapper around a Python string.
-
-Generate Plist example:
-
-    pl = dict(
-        aString="Doodah",
-        aList=["A", "B", 12, 32.1, [1, 2, 3]],
-        aFloat=0.1,
-        anInt=728,
-        aDict=dict(
-            anotherString="<hello & hi there!>",
-            aUnicodeValue=u'M\xe4ssig, Ma\xdf',
-            aTrueValue=True,
-            aFalseValue=False,
-        ),
-        someData=Data("<binary gunk>"),
-        someMoreData=Data("<lots of binary gunk>" * 10),
-        aDate=datetime.datetime.fromtimestamp(time.mktime(time.gmtime())),
-    )
-    # unicode keys are possible, but a little awkward to use:
-    pl[u'\xc5benraa'] = "That was a unicode key."
-    writePlist(pl, fileName)
-
-Parse Plist example:
-
-    pl = readPlist(pathOrFile)
-    print pl["aKey"]

-
-    """This class supports both the minimal and optional command sets.
-    Arguments can be strings or integers (where appropriate)
-    (e.g.: retr(1) and retr('1') both work equally well.
-
-    Minimal Command Set:
-            USER name               user(name)
-            PASS string             pass_(string)

-            LIST [msg]              list(msg = None)
-            RETR msg                retr(msg)
-            DELE msg                dele(msg)
-            NOOP                    noop()
-            RSET                    rset()
-            QUIT                    quit()
-
-    Optional Commands (some servers support these):
-            RPOP name               rpop(name)
-            APOP name digest        apop(name, digest)
-            TOP msg n               top(msg, n)
-            UIDL [msg]              uidl(msg = None)
-
-    Raises one exception: 'error_proto'.
-
-    Instantiate with:
-            POP3(hostname, port=110)
-
-    NB:     the POP protocol locks the mailbox from user
-            authorization until QUIT, so be sure to get in, suck
-            the messages, and quit, each time you access the
-            mailbox.
-
-            POP is a line-based protocol, which means large mail
-            messages consume lots of python cycles reading them
-            line-by-line.
-
-            If it's available on your mail server, use IMAP4
-            instead, it doesn't suffer from the two problems
-            above.

-#  something.  I wrote this when I was trying to read some heavily nested
-#  tuples with fairly non-descriptive content.  This is modeled very much
-#  after Lisp/Scheme - style pretty-printing of lists.  If you find it
-#  useful, thank small children who sleep at night.

-    """This class is used for creating reports from data generated by the
-    Profile class.  It is a "friend" of that class, and imports data either
-    by direct access to members of Profile class, or by reading in a dictionary
-    that was emitted (via marshal) from the Profile class.
-
-    The big change from the previous Profiler (in terms of raw functionality)
-    is that an "add()" method has been provided to combine Stats from
-    several distinct profile runs.  Both the constructor and the add()
-    method now take arbitrarily many file names as arguments.
-
-    All the print methods now take an argument that indicates how many lines
-    to print.  If the arg is a floating point number between 0 and 1.0, then
-    it is taken as a decimal percentage of the available lines to be printed
-    (e.g., .1 means print 10% of all available lines).  If it is an integer,
-    it is taken to mean the number of lines of data that you wish to have
-    printed.
-
-    The sort_stats() method now processes some additional options (i.e., in
-    addition to the old -1, 0, 1, or 2).  It takes an arbitrary number of
-    quoted strings to select the sort order.  For example sort_stats('time',
-    'name') sorts on the major key of 'internal function time', and on the
-    minor key of 'the name of the function'.  Look at the two tables in
-    sort_stats() and get_sort_arg_defs(self) for more examples.
-

-topics = {'assert': '\nThe ``assert`` statement\n************************\n\nAssert statements are a convenient way to insert debugging assertions\ninto a program:\n\n   assert_stmt ::= "assert" expression ["," expression]\n\nThe simple form, ``assert expression``, is equivalent to\n\n   if __debug__:\n      if not expression: raise AssertionError\n\nThe extended form, ``assert expression1, expression2``, is equivalent\nto\n\n   if __debug__:\n      if not expression1: raise AssertionError(expression2)\n\nThese equivalences assume that ``__debug__`` and ``AssertionError``\nrefer to the built-in variables with those names.  In the current\nimplementation, the built-in variable ``__debug__`` is ``True`` under\nnormal circumstances, ``False`` when optimization is requested\n(command line option -O).  The current code generator emits no code\nfor an assert statement when optimization is requested at compile\ntime.  Note that it is unnecessary to include the source code for the\nexpression that failed in the error message; it will be displayed as\npart of the stack trace.\n\nAssignments to ``__debug__`` are illegal.  The value for the built-in\nvariable is determined when the interpreter starts.\n',
- 'assignment': '\nAssignment statements\n*********************\n\nAssignment statements are used to (re)bind names to values and to\nmodify attributes or items of mutable objects:\n\n   assignment_stmt ::= (target_list "=")+ (expression_list | yield_expression)\n   target_list     ::= target ("," target)* [","]\n   target          ::= identifier\n              | "(" target_list ")"\n              | "[" target_list "]"\n              | attributeref\n              | subscription\n              | slicing\n\n(See section *Primaries* for the syntax definitions for the last three\nsymbols.)\n\nAn assignment statement evaluates the expression list (remember that\nthis can be a single expression or a comma-separated list, the latter\nyielding a tuple) and assigns the single resulting object to each of\nthe target lists, from left to right.\n\nAssignment is defined recursively depending on the form of the target\n(list). When a target is part of a mutable object (an attribute\nreference, subscription or slicing), the mutable object must\nultimately perform the assignment and decide about its validity, and\nmay raise an exception if the assignment is unacceptable.  The rules\nobserved by various types and the exceptions raised are given with the\ndefinition of the object types (see section *The standard type\nhierarchy*).\n\nAssignment of an object to a target list is recursively defined as\nfollows.\n\n* If the target list is a single target: The object is assigned to\n  that target.\n\n* If the target list is a comma-separated list of targets: The object\n  must be an iterable with the same number of items as there are\n  targets in the target list, and the items are assigned, from left to\n  right, to the corresponding targets.\n\nAssignment of an object to a single target is recursively defined as\nfollows.\n\n* If the target is an identifier (name):\n\n  * If the name does not occur in a ``global`` statement in the\n    current code block: the name is bound to the object in the current\n    local namespace.\n\n  * Otherwise: the name is bound to the object in the current global\n    namespace.\n\n  The name is rebound if it was already bound.  This may cause the\n  reference count for the object previously bound to the name to reach\n  zero, causing the object to be deallocated and its destructor (if it\n  has one) to be called.\n\n* If the target is a target list enclosed in parentheses or in square\n  brackets: The object must be an iterable with the same number of\n  items as there are targets in the target list, and its items are\n  assigned, from left to right, to the corresponding targets.\n\n* If the target is an attribute reference: The primary expression in\n  the reference is evaluated.  It should yield an object with\n  assignable attributes; if this is not the case, ``TypeError`` is\n  raised.  That object is then asked to assign the assigned object to\n  the given attribute; if it cannot perform the assignment, it raises\n  an exception (usually but not necessarily ``AttributeError``).\n\n  Note: If the object is a class instance and the attribute reference\n  occurs on both sides of the assignment operator, the RHS expression,\n  ``a.x`` can access either an instance attribute or (if no instance\n  attribute exists) a class attribute.  The LHS target ``a.x`` is\n  always set as an instance attribute, creating it if necessary.\n  Thus, the two occurrences of ``a.x`` do not necessarily refer to the\n  same attribute: if the RHS expression refers to a class attribute,\n  the LHS creates a new instance attribute as the target of the\n  assignment:\n\n     class Cls:\n         x = 3             # class variable\n     inst = Cls()\n     inst.x = inst.x + 1   # writes inst.x as 4 leaving Cls.x as 3\n\n  This description does not necessarily apply to descriptor\n  attributes, such as properties created with ``property()``.\n\n* If the target is a subscription: The primary expression in the\n  reference is evaluated.  It should yield either a mutable sequence\n  object (such as a list) or a mapping object (such as a dictionary).\n  Next, the subscript expression is evaluated.\n\n  If the primary is a mutable sequence object (such as a list), the\n  subscript must yield a plain integer.  If it is negative, the\n  sequence\'s length is added to it. The resulting value must be a\n  nonnegative integer less than the sequence\'s length, and the\n  sequence is asked to assign the assigned object to its item with\n  that index.  If the index is out of range, ``IndexError`` is raised\n  (assignment to a subscripted sequence cannot add new items to a\n  list).\n\n  If the primary is a mapping object (such as a dictionary), the\n  subscript must have a type compatible with the mapping\'s key type,\n  and the mapping is then asked to create a key/datum pair which maps\n  the subscript to the assigned object.  This can either replace an\n  existing key/value pair with the same key value, or insert a new\n  key/value pair (if no key with the same value existed).\n\n* If the target is a slicing: The primary expression in the reference\n  is evaluated.  It should yield a mutable sequence object (such as a\n  list).  The assigned object should be a sequence object of the same\n  type.  Next, the lower and upper bound expressions are evaluated,\n  insofar they are present; defaults are zero and the sequence\'s\n  length.  The bounds should evaluate to (small) integers.  If either\n  bound is negative, the sequence\'s length is added to it. The\n  resulting bounds are clipped to lie between zero and the sequence\'s\n  length, inclusive.  Finally, the sequence object is asked to replace\n  the slice with the items of the assigned sequence.  The length of\n  the slice may be different from the length of the assigned sequence,\n  thus changing the length of the target sequence, if the object\n  allows it.\n\n**CPython implementation detail:** In the current implementation, the\nsyntax for targets is taken to be the same as for expressions, and\ninvalid syntax is rejected during the code generation phase, causing\nless detailed error messages.\n\nWARNING: Although the definition of assignment implies that overlaps\nbetween the left-hand side and the right-hand side are \'safe\' (for\nexample ``a, b = b, a`` swaps two variables), overlaps *within* the\ncollection of assigned-to variables are not safe!

In\nthe augmented version, ``x`` is only evaluated once. Also, when\npossible, the actual operation is performed *in-place*, meaning that\nrather than creating a new object and assigning that to the target,\nthe old object is modified instead.\n\nWith the exception of assigning to tuples and multiple targets in a\nsingle statement, the assignment done by augmented assignment\nstatements is handled the same way as normal assignments. Similarly,\nwith the exception of the possible *in-place* behavior, the binary\noperation performed by augmented assignment is the same as the normal\nbinary operations.\n\nFor targets which are attribute references, the same *caveat about\nclass and instance attributes* applies as for regular assignments.\n',
- 'atom-identifiers': '\nIdentifiers (Names)\n*******************\n\nAn identifier occurring as an atom is a name.  See section\n*Identifiers and keywords* for lexical definition and section *Naming\nand binding* for documentation of naming and binding.\n\nWhen the name is bound to an object, evaluation of the atom yields\nthat object. When a name is not bound, an attempt to evaluate it\nraises a ``NameError`` exception.\n\n**Private name mangling:** When an identifier that textually occurs in\na class definition begins with two or more underscore characters and\ndoes not end in two or more underscores, it is considered a *private\nname* of that class. Private names are transformed to a longer form\nbefore code is generated for them.  The transformation inserts the\nclass name, with leading underscores removed and a single underscore\ninserted, in front of the name.  For example, the identifier\n``__spam`` occurring in a class named ``Ham`` will be transformed to\n``_Ham__spam``.  This transformation is independent of the syntactical\ncontext in which the identifier is used.  If the transformed name is\nextremely long (longer than 255 characters), implementation defined\ntruncation may happen. If the class name consists only of underscores,\nno transformation is done.\n',
- 'atom-literals': "\nLiterals\n********\n\nPython supports string literals and various numeric literals:\n\n   literal ::= stringliteral | integer | longinteger\n               | floatnumber | imagnumber\n\nEvaluation of a literal yields an object of the given type (string,\ninteger, long integer, floating point number, complex number) with the\ngiven value.  The value may be approximated in the case of floating\npoint and imaginary (complex) literals.  See section *Literals* for\ndetails.\n\nAll literals correspond to immutable data types, and hence the\nobject's identity is less important than its value.  Multiple\nevaluations of literals with the same value (either the same\noccurrence in the program text or a different occurrence) may obtain\nthe same object or a different object with the same value.\n",
- 'attribute-access': '\nCustomizing attribute access\n****************************\n\nThe following methods can be defined to customize the meaning of\nattribute access (use of, assignment to, or deletion of ``x.name``)\nfor class instances.\n\nobject.__getattr__(self, name)\n\n   Called when an attribute lookup has not found the attribute in the\n   usual places (i.e. it is not an instance attribute nor is it found\n   in the class tree for ``self``).  ``name`` is the attribute name.\n   This method should return the (computed) attribute value or raise\n   an ``AttributeError`` exception.\n\n   Note that if the attribute is found through the normal mechanism,\n   ``__getattr__()`` is not called.  (This is an intentional asymmetry\n   between ``__getattr__()`` and ``__setattr__()``.) This is done both\n   for efficiency reasons and because otherwise ``__getattr__()``\n   would have no way to access other attributes of the instance.  Note\n   that at least for instance variables, you can fake total control by\n   not inserting any values in the instance attribute dictionary (but\n   instead inserting them in another object).  See the\n   ``__getattribute__()`` method below for a way to actually get total\n   control in new-style classes.\n\nobject.__setattr__(self, name, value)\n\n   Called when an attribute assignment is attempted.  This is called\n   instead of the normal mechanism (i.e. store the value in the\n   instance dictionary).  *name* is the attribute name, *value* is the\n   value to be assigned to it.\n\n   If ``__setattr__()`` wants to assign to an instance attribute, it\n   should not simply execute ``self.name = value`` --- this would\n   cause a recursive call to itself.  Instead, it should insert the\n   value in the dictionary of instance attributes, e.g.,\n   ``self.__dict__[name] = value``.  For new-style classes, rather\n   than accessing the instance dictionary, it should call the base\n   class method with the same name, for example,\n   ``object.__setattr__(self, name, value)``.\n\nobject.__delattr__(self, name)\n\n   Like ``__setattr__()`` but for attribute deletion instead of\n   assignment.  This should only be implemented if ``del obj.name`` is\n   meaningful for the object.\n\n\nMore attribute access for new-style classes\n===========================================\n\nThe following methods only apply to new-style classes.\n\nobject.__getattribute__(self, name)\n\n   Called unconditionally to implement attribute accesses for\n   instances of the class. If the class also defines\n   ``__getattr__()``, the latter will not be called unless\n   ``__getattribute__()`` either calls it explicitly or raises an\n   ``AttributeError``. This method should return the (computed)\n   attribute value or raise an ``AttributeError`` exception. In order\n   to avoid infinite recursion in this method, its implementation\n   should always call the base class method with the same name to\n   access any attributes it needs, for example,\n   ``object.__getattribute__(self, name)``.\n\n   Note: This method may still be bypassed when looking up special methods\n     as the result of implicit invocation via language syntax or\n     built-in functions. See *Special method lookup for new-style\n     classes*.\n\n\nImplementing Descriptors\n========================\n\nThe following methods only apply when an instance of the class\ncontaining the method (a so-called *descriptor* class) appears in an\n*owner* class (the descriptor must be in either the owner\'s class\ndictionary or in the class dictionary for one of its parents).  In the\nexamples below, "the attribute" refers to the attribute whose name is\nthe key of the property in the owner class\' ``__dict__``.\n\nobject.__get__(self, instance, owner)\n\n   Called to get the attribute of the owner class (class attribute\n   access) or of an instance of that class (instance attribute\n   access). *owner* is always the owner class, while *instance* is the\n   instance that the attribute was accessed through, or ``None`` when\n   the attribute is accessed through the *owner*.  This method should\n   return the (computed) attribute value or raise an\n   ``AttributeError`` exception.\n\nobject.__set__(self, instance, value)\n\n   Called to set the attribute on an instance *instance* of the owner\n   class to a new value, *value*.\n\nobject.__delete__(self, instance)\n\n   Called to delete the attribute on an instance *instance* of the\n   owner class.\n\n\nInvoking Descriptors\n====================\n\nIn general, a descriptor is an object attribute with "binding\nbehavior", one whose attribute access has been overridden by methods\nin the descriptor protocol:  ``__get__()``, ``__set__()``, and\n``__delete__()``. If any of those methods are defined for an object,\nit is said to be a descriptor.\n\nThe default behavior for attribute access is to get, set, or delete\nthe attribute from an object\'s dictionary. For instance, ``a.x`` has a\nlookup chain starting with ``a.__dict__[\'x\']``, then\n``type(a).__dict__[\'x\']``, and continuing through the base classes of\n``type(a)`` excluding metaclasses.\n\nHowever, if the looked-up value is an object defining one of the\ndescriptor methods, then Python may override the default behavior and\ninvoke the descriptor method instead.  Where this occurs in the\nprecedence chain depends on which descriptor methods were defined and\nhow they were called.  Note that descriptors are only invoked for new\nstyle objects or classes (ones that subclass ``object()`` or\n``type()``).\n\nThe starting point for descriptor invocation is a binding, ``a.x``.\nHow the arguments are assembled depends on ``a``:\n\nDirect Call\n   The simplest and least common call is when user code directly\n   invokes a descriptor method:    ``x.__get__(a)``.\n\nInstance Binding\n   If binding to a new-style object instance, ``a.x`` is transformed\n   into the call: ``type(a).__dict__[\'x\'].__get__(a, type(a))``.\n\nClass Binding\n   If binding to a new-style class, ``A.x`` is transformed into the\n   call: ``A.__dict__[\'x\'].__get__(None, A)``.\n\nSuper Binding\n   If ``a`` is an instance of ``super``, then the binding ``super(B,\n   obj).m()`` searches ``obj.__class__.__mro__`` for the base class\n   ``A`` immediately preceding ``B`` and then invokes the descriptor\n   with the call: ``A.__dict__[\'m\'].__get__(obj, obj.__class__)``.\n\nFor instance bindings, the precedence of descriptor invocation depends\non the which descriptor methods are defined.  A descriptor can define\nany combination of ``__get__()``, ``__set__()`` and ``__delete__()``.\nIf it does not define ``__get__()``, then accessing the attribute will\nreturn the descriptor object itself unless there is a value in the\nobject\'s instance dictionary.  If the descriptor defines ``__set__()``\nand/or ``__delete__()``, it is a data descriptor; if it defines\nneither, it is a non-data descriptor.  Normally, data descriptors\ndefine both ``__get__()`` and ``__set__()``, while non-data\ndescriptors have just the ``__get__()`` method.  Data descriptors with\n``__set__()`` and ``__get__()`` defined always override a redefinition\nin an instance dictionary.  In contrast, non-data descriptors can be\noverridden by instances.\n\nPython methods (including ``staticmethod()`` and ``classmethod()``)\nare implemented as non-data descriptors.  Accordingly, instances can\nredefine and override methods.  This allows individual instances to\nacquire behaviors that differ from other instances of the same class.\n\nThe ``property()`` function is implemented as a data descriptor.\nAccordingly, instances cannot override the behavior of a property.\n\n\n__slots__\n=========\n\nBy default, instances of both old and new-style classes have a\ndictionary for attribute storage.  This wastes space for objects\nhaving very few instance variables.  The space consumption can become\nacute when creating large numbers of instances.\n\nThe default can be overridden by defining *__slots__* in a new-style\nclass definition.  The *__slots__* declaration takes a sequence of\ninstance variables and reserves just enough space in each instance to\nhold a value for each variable.  Space is saved because *__dict__* is\nnot created for each instance.\n\n__slots__\n\n   This class variable can be assigned a string, iterable, or sequence\n   of strings with variable names used by instances.  If defined in a\n   new-style class, *__slots__* reserves space for the declared\n   variables and prevents the automatic creation of *__dict__* and\n   *__weakref__* for each instance.\n\n   New in version 2.2.\n\nNotes on using *__slots__*\n\n* When inheriting from a class without *__slots__*, the *__dict__*\n  attribute of that class will always be accessible, so a *__slots__*\n  definition in the subclass is meaningless.\n\n* Without a *__dict__* variable, instances cannot be assigned new\n  variables not listed in the *__slots__* definition.  Attempts to\n  assign to an unlisted variable name raises ``AttributeError``. If\n  dynamic assignment of new variables is desired, then add\n  ``\'__dict__\'`` to the sequence of strings in the *__slots__*\n  declaration.\n\n  Changed in version 2.3: Previously, adding ``\'__dict__\'`` to the\n  *__slots__* declaration would not enable the assignment of new\n  attributes not specifically listed in the sequence of instance\n  variable names.\n\n* Without a *__weakref__* variable for each instance, classes defining\n  *__slots__* do not support weak references to its instances. If weak\n  reference support is needed, then add ``\'__weakref__\'`` to the\n  sequence of strings in the *__slots__* declaration.\n\n  Changed in version 2.3: Previously, adding ``\'__weakref__\'`` to the\n  *__slots__* declaration would not enable support for weak\n  references.\n\n* *__slots__* are implemented at the class level by creating\n  descriptors (*Implementing Descriptors*) for each variable name.  As\n  a result, class attributes cannot be used to set default values for\n  instance variables defined by *__slots__*; otherwise, the class\n  attribute would overwrite the descriptor assignment.\n\n* The action of a *__slots__* declaration is limited to the class\n  where it is defined.  As a result, subclasses will have a *__dict__*\n  unless they also define *__slots__* (which must only contain names\n  of any *additional* slots).\n\n* If a class defines a slot also defined in a base class, the instance\n  variable defined by the base class slot is inaccessible (except by\n  retrieving its descriptor directly from the base class). This\n  renders the meaning of the program undefined.  In the future, a\n  check may be added to prevent this.\n\n* Nonempty *__slots__* does not work for classes derived from\n  "variable-length" built-in types such as ``long``, ``str`` and\n  ``tuple``.\n\n* Any non-string iterable may be assigned to *__slots__*. Mappings may\n  also be used; however, in the future, special meaning may be\n  assigned to the values corresponding to each key.\n\n* *__class__* assignment works only if both classes have the same\n  *__slots__*.\n\n  Changed in version 2.6: Previously, *__class__* assignment raised an\n  error if either new or old class had *__slots__*.\n',

- 'binary': '\nBinary arithmetic operations\n****************************\n\nThe binary arithmetic operations have the conventional priority\nlevels.  Note that some of these operations also apply to certain non-\nnumeric types.  Apart from the power operator, there are only two\nlevels, one for multiplicative operators and one for additive\noperators:\n\n   m_expr ::= u_expr | m_expr "*" u_expr | m_expr "//" u_expr | m_expr "/" u_expr\n              | m_expr "%" u_expr\n   a_expr ::= m_expr | a_expr "+" m_expr | a_expr "-" m_expr\n\nThe ``*`` (multiplication) operator yields the product of its\narguments.  The arguments must either both be numbers, or one argument\nmust be an integer (plain or long) and the other must be a sequence.\nIn the former case, the numbers are converted to a common type and\nthen multiplied together.  In the latter case, sequence repetition is\nperformed; a negative repetition factor yields an empty sequence.\n\nThe ``/`` (division) and ``//`` (floor division) operators yield the\nquotient of their arguments.  The numeric arguments are first\nconverted to a common type. Plain or long integer division yields an\ninteger of the same type; the result is that of mathematical division\nwith the \'floor\' function applied to the result. Division by zero\nraises the ``ZeroDivisionError`` exception.\n\nThe ``%`` (modulo) operator yields the remainder from the division of\nthe first argument by the second.  The numeric arguments are first\nconverted to a common type.  A zero right argument raises the\n``ZeroDivisionError`` exception.  The arguments may be floating point\nnumbers, e.g., ``3.14%0.7`` equals ``0.34`` (since ``3.14`` equals\n``4*0.7 + 0.34``.)  The modulo operator always yields a result with\nthe same sign as its second operand (or zero); the absolute value of\nthe result is strictly smaller than the absolute value of the second\noperand [2].\n\nThe integer division and modulo operators are connected by the\nfollowing identity: ``x == (x/y)*y + (x%y)``.  Integer division and\nmodulo are also connected with the built-in function ``divmod()``:\n``divmod(x, y) == (x/y, x%y)``.  These identities don\'t hold for\nfloating point numbers; there similar identities hold approximately\nwhere ``x/y`` is replaced by ``floor(x/y)`` or ``floor(x/y) - 1`` [3].\n\nIn addition to performing the modulo operation on numbers, the ``%``\noperator is also overloaded by string and unicode objects to perform\nstring formatting (also known as interpolation). The syntax for string\nformatting is described in the Python Library Reference, section\n*String Formatting Operations*.\n\nDeprecated since version 2.3: The floor division operator, the modulo\noperator, and the ``divmod()`` function are no longer defined for\ncomplex numbers.

If there are any\nunfilled slots for which no default value is specified, a\n``TypeError`` exception is raised.  Otherwise, the list of filled\nslots is used as the argument list for the call.\n\n**CPython implementation detail:** An implementation may provide\nbuilt-in functions whose positional parameters do not have names, even\nif they are \'named\' for the purpose of documentation, and which\ntherefore cannot be supplied by keyword.  In CPython, this is the case\nfor functions implemented in C that use ``PyArg_ParseTuple()`` to\nparse their arguments.\n\nIf there are more positional arguments than there are formal parameter\nslots, a ``TypeError`` exception is raised, unless a formal parameter\nusing the syntax ``*identifier`` is present; in this case, that formal\nparameter receives a tuple containing the excess positional arguments\n(or an empty tuple if there were no excess positional arguments).\n\nIf any keyword argument does not correspond to a formal parameter\nname, a ``TypeError`` exception is raised, unless a formal parameter\nusing the syntax ``**identifier`` is present; in this case, that\nformal parameter receives a dictionary containing the excess keyword\narguments (using the keywords as keys and the argument values as\ncorresponding values), or a (new) empty dictionary if there were no\nexcess keyword arguments.\n\nIf the syntax ``*expression`` appears in the function call,\n``expression`` must evaluate to an iterable.  Elements from this\niterable are treated as if they were additional positional arguments;\nif there are positional arguments *x1*, ..., *xN*, and ``expression``\nevaluates to a sequence *y1*, ..., *yM*, this is equivalent to a call\nwith M+N positional arguments *x1*, ..., *xN*, *y1*, ..., *yM*.\n\nA consequence of this is that although the ``*expression`` syntax may\nappear *after* some keyword arguments, it is processed *before* the\nkeyword arguments (and the ``**expression`` argument, if any -- see\nbelow).  So:\n\n   >>> def f(a, b):\n   ...  print a, b\n   ...\n   >>> f(b=1, *(2,))\n   2 1\n   >>> f(a=1, *(2,))\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in ?\n   TypeError: f() got multiple values for keyword argument \'a\'\n   >>> f(1, *(2,))\n   1 2\n\nIt is unusual for both keyword arguments and the ``*expression``\nsyntax to be used in the same call, so in practice this confusion does\nnot arise.\n\nIf the syntax ``**expression`` appears in the function call,\n``expression`` must evaluate to a mapping, the contents of which are\ntreated as additional keyword arguments.  In the case of a keyword\nappearing in both ``expression`` and as an explicit keyword argument,\na ``TypeError`` exception is raised.\n\nFormal parameters using the syntax ``*identifier`` or ``**identifier``\ncannot be used as positional argument slots or as keyword argument\nnames.  Formal parameters using the syntax ``(sublist)`` cannot be\nused as keyword argument names; the outermost sublist corresponds to a\nsingle unnamed argument slot, and the argument value is assigned to\nthe sublist using the usual tuple assignment rules after all other\nparameter processing is done.\n\nA call always returns some value, possibly ``None``, unless it raises\nan exception.  How this value is computed depends on the type of the\ncallable object.\n\nIf it is---\n\na user-defined function:\n   The code block for the function is executed, passing it the\n   argument list.  The first thing the code block will do is bind the\n   formal parameters to the arguments; this is described in section\n   *Function definitions*.  When the code block executes a ``return``\n   statement, this specifies the return value of the function call.\n\na built-in function or method:\n   The result is up to the interpreter; see *Built-in Functions* for\n   the descriptions of built-in functions and methods.\n\na class object:\n   A new instance of that class is returned.\n\na class instance method:\n   The corresponding user-defined function is called, with an argument\n   list that is one longer than the argument list of the call: the\n   instance becomes the first argument.\n\na class instance:\n   The class must define a ``__call__()`` method; the effect is then\n   the same as if that method was called.\n',
- 'class': '\nClass definitions\n*****************\n\nA class definition defines a class object (see section *The standard\ntype hierarchy*):\n\n   classdef    ::= "class" classname [inheritance] ":" suite\n   inheritance ::= "(" [expression_list] ")"\n   classname   ::= identifier\n\nA class definition is an executable statement.  It first evaluates the\ninheritance list, if present.  Each item in the inheritance list\nshould evaluate to a class object or class type which allows\nsubclassing.  The class\'s suite is then executed in a new execution\nframe (see section *Naming and binding*), using a newly created local\nnamespace and the original global namespace. (Usually, the suite\ncontains only function definitions.)  When the class\'s suite finishes\nexecution, its execution frame is discarded but its local namespace is\nsaved. [4] A class object is then created using the inheritance list\nfor the base classes and the saved local namespace for the attribute\ndictionary.  The class name is bound to this class object in the\noriginal local namespace.\n\n**Programmer\'s note:** Variables defined in the class definition are\nclass variables; they are shared by all instances.  To create instance\nvariables, they can be set in a method with ``self.name = value``.\nBoth class and instance variables are accessible through the notation\n"``self.name``", and an instance variable hides a class variable with\nthe same name when accessed in this way. Class variables can be used\nas defaults for instance variables, but using mutable values there can\nlead to unexpected results.  For *new-style class*es, descriptors can\nbe used to create instance variables with different implementation\ndetails.\n\nClass definitions, like function definitions, may be wrapped by one or\nmore *decorator* expressions.  The evaluation rules for the decorator\nexpressions are the same as for functions.  The result must be a class\nobject, which is then bound to the class name.\n\n-[ Footnotes ]-\n\n[1] The exception is propagated to the invocation stack unless there\n    is a ``finally`` clause which happens to raise another exception.\n    That new exception causes the old one to be lost.\n\n[2] Currently, control "flows off the end" except in the case of an\n    exception or the execution of a ``return``, ``continue``, or\n    ``break`` statement.\n\n[3] A string literal appearing as the first statement in the function\n    body is transformed into the function\'s ``__doc__`` attribute and\n    therefore the function\'s *docstring*.\n\n[4] A string literal appearing as the first statement in the class\n    body is transformed into the namespace\'s ``__doc__`` item and\n    therefore the class\'s *docstring*.\n',
- 'comparisons': '\nComparisons\n***********\n\nUnlike C, all comparison operations in Python have the same priority,\nwhich is lower than that of any arithmetic, shifting or bitwise\noperation.  Also unlike C, expressions like ``a < b < c`` have the\ninterpretation that is conventional in mathematics:\n\n   comparison    ::= or_expr ( comp_operator or_expr )*\n   comp_operator ::= "<" | ">" | "==" | ">=" | "<=" | "<>" | "!="\n                     | "is" ["not"] | ["not"] "in"\n\nComparisons yield boolean values: ``True`` or ``False``.\n\nComparisons can be chained arbitrarily, e.g., ``x < y <= z`` is\nequivalent to ``x < y and y <= z``, except that ``y`` is evaluated\nonly once (but in both cases ``z`` is not evaluated at all when ``x <\ny`` is found to be false).\n\nFormally, if *a*, *b*, *c*, ..., *y*, *z* are expressions and *op1*,\n*op2*, ..., *opN* are comparison operators, then ``a op1 b op2 c ... y\nopN z`` is equivalent to ``a op1 b and b op2 c and ... y opN z``,\nexcept that each expression is evaluated at most once.\n\nNote that ``a op1 b op2 c`` doesn\'t imply any kind of comparison\nbetween *a* and *c*, so that, e.g., ``x < y > z`` is perfectly legal\n(though perhaps not pretty).\n\nThe forms ``<>`` and ``!=`` are equivalent; for consistency with C,\n``!=`` is preferred; where ``!=`` is mentioned below ``<>`` is also\naccepted.  The ``<>`` spelling is considered obsolescent.\n\nThe operators ``<``, ``>``, ``==``, ``>=``, ``<=``, and ``!=`` compare\nthe values of two objects.  The objects need not have the same type.\nIf both are numbers, they are converted to a common type.  Otherwise,\nobjects of different types *always* compare unequal, and are ordered\nconsistently but arbitrarily. You can control comparison behavior of\nobjects of non-built-in types by defining a ``__cmp__`` method or rich\ncomparison methods like ``__gt__``, described in section *Special\nmethod names*.\n\n(This unusual definition of comparison was used to simplify the\ndefinition of operations like sorting and the ``in`` and ``not in``\noperators. In the future, the comparison rules for objects of\ndifferent types are likely to change.)\n\nComparison of objects of the same type depends on the type:\n\n* Numbers are compared arithmetically.\n\n* Strings are compared lexicographically using the numeric equivalents\n  (the result of the built-in function ``ord()``) of their characters.\n  Unicode and 8-bit strings are fully interoperable in this behavior.\n  [4]\n\n* Tuples and lists are compared lexicographically using comparison of\n  corresponding elements.  This means that to compare equal, each\n  element must compare equal and the two sequences must be of the same\n  type and have the same length.\n\n  If not equal, the sequences are ordered the same as their first\n  differing elements.  For example, ``cmp([1,2,x], [1,2,y])`` returns\n  the same as ``cmp(x,y)``.  If the corresponding element does not\n  exist, the shorter sequence is ordered first (for example, ``[1,2] <\n  [1,2,3]``).\n\n* Mappings (dictionaries) compare equal if and only if their sorted\n  (key, value) lists compare equal. [5] Outcomes other than equality\n  are resolved consistently, but are not otherwise defined. [6]\n\n* Most other objects of built-in types compare unequal unless they are\n  the same object; the choice whether one object is considered smaller\n  or larger than another one is made arbitrarily but consistently\n  within one execution of a program.\n\nThe operators ``in`` and ``not in`` test for collection membership.\n``x in s`` evaluates to true if *x* is a member of the collection *s*,\nand false otherwise.  ``x not in s`` returns the negation of ``x in\ns``. The collection membership test has traditionally been bound to\nsequences; an object is a member of a collection if the collection is\na sequence and contains an element equal to that object.  However, it\nmake sense for many other object types to support membership tests\nwithout being a sequence.  In particular, dictionaries (for keys) and\nsets support membership testing.\n\nFor the list and tuple types, ``x in y`` is true if and only if there\nexists an index *i* such that ``x == y[i]`` is true.\n\nFor the Unicode and string types, ``x in y`` is true if and only if\n*x* is a substring of *y*.  An equivalent test is ``y.find(x) != -1``.\nNote, *x* and *y* need not be the same type; consequently, ``u\'ab\' in\n\'abc\'`` will return ``True``. Empty strings are always considered to\nbe a substring of any other string, so ``"" in "abc"`` will return\n``True``.\n\nChanged in version 2.3: Previously, *x* was required to be a string of\nlength ``1``.\n\nFor user-defined classes which define the ``__contains__()`` method,\n``x in y`` is true if and only if ``y.__contains__(x)`` is true.\n\nFor user-defined classes which do not define ``__contains__()`` but do\ndefine ``__iter__()``, ``x in y`` is true if some value ``z`` with ``x\n== z`` is produced while iterating over ``y``.  If an exception is\nraised during the iteration, it is as if ``in`` raised that exception.\n\nLastly, the old-style iteration protocol is tried: if a class defines\n``__getitem__()``, ``x in y`` is true if and only if there is a non-\nnegative integer index *i* such that ``x == y[i]``, and all lower\ninteger indices do not raise ``IndexError`` exception. (If any other\nexception is raised, it is as if ``in`` raised that exception).\n\nThe operator ``not in`` is defined to have the inverse true value of\n``in``.\n\nThe operators ``is`` and ``is not`` test for object identity: ``x is\ny`` is true if and only if *x* and *y* are the same object.  ``x is\nnot y`` yields the inverse truth value.

- 'compound': '\nCompound statements\n*******************\n\nCompound statements contain (groups of) other statements; they affect\nor control the execution of those other statements in some way.  In\ngeneral, compound statements span multiple lines, although in simple\nincarnations a whole compound statement may be contained in one line.\n\nThe ``if``, ``while`` and ``for`` statements implement traditional\ncontrol flow constructs.  ``try`` specifies exception handlers and/or\ncleanup code for a group of statements.  Function and class\ndefinitions are also syntactically compound statements.\n\nCompound statements consist of one or more \'clauses.\'  A clause\nconsists of a header and a \'suite.\'  The clause headers of a\nparticular compound statement are all at the same indentation level.\nEach clause header begins with a uniquely identifying keyword and ends\nwith a colon.  A suite is a group of statements controlled by a\nclause.  A suite can be one or more semicolon-separated simple\nstatements on the same line as the header, following the header\'s\ncolon, or it can be one or more indented statements on subsequent\nlines.  Only the latter form of suite can contain nested compound\nstatements; the following is illegal, mostly because it wouldn\'t be\nclear to which ``if`` clause a following ``else`` clause would belong:\n\n   if test1: if test2: print x\n\nAlso note that the semicolon binds tighter than the colon in this\ncontext, so that in the following example, either all or none of the\n``print`` statements are executed:\n\n   if x < y < z: print x; print y; print z\n\nSummarizing:\n\n   compound_stmt ::= if_stmt\n                     | while_stmt\n                     | for_stmt\n                     | try_stmt\n                     | with_stmt\n                     | funcdef\n                     | classdef\n                     | decorated\n   suite         ::= stmt_list NEWLINE | NEWLINE INDENT statement+ DEDENT\n   statement     ::= stmt_list NEWLINE | compound_stmt\n   stmt_list     ::= simple_stmt (";" simple_stmt)* [";"]\n\nNote that statements always end in a ``NEWLINE`` possibly followed by\na ``DEDENT``. Also note that optional continuation clauses always\nbegin with a keyword that cannot start a statement, thus there are no\nambiguities (the \'dangling ``else``\' problem is solved in Python by\nrequiring nested ``if`` statements to be indented).\n\nThe formatting of the grammar rules in the following sections places\neach clause on a separate line for clarity.\n\n\nThe ``if`` statement\n====================\n\nThe ``if`` statement is used for conditional execution:\n\n   if_stmt ::= "if" expression ":" suite\n               ( "elif" expression ":" suite )*\n               ["else" ":" suite]\n\nIt selects exactly one of the suites by evaluating the expressions one\nby one until one is found to be true (see section *Boolean operations*\nfor the definition of true and false); then that suite is executed\n(and no other part of the ``if`` statement is executed or evaluated).\nIf all expressions are false, the suite of the ``else`` clause, if\npresent, is executed.\n\n\nThe ``while`` statement\n=======================\n\nThe ``while`` statement is used for repeated execution as long as an\nexpression is true:\n\n   while_stmt ::= "while" expression ":" suite\n                  ["else" ":" suite]\n\nThis repeatedly tests the expression and, if it is true, executes the\nfirst suite; if the expression is false (which may be the first time\nit is tested) the suite of the ``else`` clause, if present, is\nexecuted and the loop terminates.\n\nA ``break`` statement executed in the first suite terminates the loop\nwithout executing the ``else`` clause\'s suite.  A ``continue``\nstatement executed in the first suite skips the rest of the suite and\ngoes back to testing the expression.\n\n\nThe ``for`` statement\n=====================\n\nThe ``for`` statement is used to iterate over the elements of a\nsequence (such as a string, tuple or list) or other iterable object:\n\n   for_stmt ::= "for" target_list "in" expression_list ":" suite\n                ["else" ":" suite]\n\nThe expression list is evaluated once; it should yield an iterable\nobject.  An iterator is created for the result of the\n``expression_list``.  The suite is then executed once for each item\nprovided by the iterator, in the order of ascending indices.  Each\nitem in turn is assigned to the target list using the standard rules\nfor assignments, and then the suite is executed.  When the items are\nexhausted (which is immediately when the sequence is empty), the suite\nin the ``else`` clause, if present, is executed, and the loop\nterminates.\n\nA ``break`` statement executed in the first suite terminates the loop\nwithout executing the ``else`` clause\'s suite.  A ``continue``\nstatement executed in the first suite skips the rest of the suite and\ncontinues with the next item, or with the ``else`` clause if there was\nno next item.\n\nThe suite may assign to the variable(s) in the target list; this does\nnot affect the next item assigned to it.\n\nThe target list is not deleted when the loop is finished, but if the\nsequence is empty, it will not have been assigned to at all by the\nloop.  Hint: the built-in function ``range()`` returns a sequence of\nintegers suitable to emulate the effect of Pascal\'s ``for i := a to b\ndo``; e.g., ``range(3)`` returns the list ``[0, 1, 2]``.\n\nNote: There is a subtlety when the sequence is being modified by the loop\n  (this can only occur for mutable sequences, i.e. lists). An internal\n  counter is used to keep track of which item is used next, and this\n  is incremented on each iteration.  When this counter has reached the\n  length of the sequence the loop terminates.  This means that if the\n  suite deletes the current (or a previous) item from the sequence,\n  the next item will be skipped (since it gets the index of the\n  current item which has already been treated).  Likewise, if the\n  suite inserts an item in the sequence before the current item, the\n  current item will be treated again the next time through the loop.\n  This can lead to nasty bugs that can be avoided by making a\n  temporary copy using a slice of the whole sequence, e.g.,\n\n     for x in a[:]:\n         if x < 0: a.remove(x)\n\n\nThe ``try`` statement\n=====================\n\nThe ``try`` statement specifies exception handlers and/or cleanup code\nfor a group of statements:\n\n   try_stmt  ::= try1_stmt | try2_stmt\n   try1_stmt ::= "try" ":" suite\n                 ("except" [expression [("as" | ",") target]] ":" suite)+\n                 ["else" ":" suite]\n                 ["finally" ":" suite]\n   try2_stmt ::= "try" ":" suite\n                 "finally" ":" suite\n\nChanged in version 2.5: In previous versions of Python,\n``try``...``except``...``finally`` did not work. ``try``...``except``\nhad to be nested in ``try``...``finally``.\n\nThe ``except`` clause(s) specify one or more exception handlers. When\nno exception occurs in the ``try`` clause, no exception handler is\nexecuted. When an exception occurs in the ``try`` suite, a search for\nan exception handler is started.  This search inspects the except\nclauses in turn until one is found that matches the exception.  An\nexpression-less except clause, if present, must be last; it matches\nany exception.  For an except clause with an expression, that\nexpression is evaluated, and the clause matches the exception if the\nresulting object is "compatible" with the exception.  An object is\ncompatible with an exception if it is the class or a base class of the\nexception object, or a tuple containing an item compatible with the\nexception.\n\nIf no except clause matches the exception, the search for an exception\nhandler continues in the surrounding code and on the invocation stack.\n[1]\n\nIf the evaluation of an expression in the header of an except clause\nraises an exception, the original search for a handler is canceled and\na search starts for the new exception in the surrounding code and on\nthe call stack (it is treated as if the entire ``try`` statement\nraised the exception).\n\nWhen a matching except clause is found, the exception is assigned to\nthe target specified in that except clause, if present, and the except\nclause\'s suite is executed.  All except clauses must have an\nexecutable block.  When the end of this block is reached, execution\ncontinues normally after the entire try statement.  (This means that\nif two nested handlers exist for the same exception, and the exception\noccurs in the try clause of the inner handler, the outer handler will\nnot handle the exception.)\n\nBefore an except clause\'s suite is executed, details about the\nexception are assigned to three variables in the ``sys`` module:\n``sys.exc_type`` receives the object identifying the exception;\n``sys.exc_value`` receives the exception\'s parameter;\n``sys.exc_traceback`` receives a traceback object (see section *The\nstandard type hierarchy*) identifying the point in the program where\nthe exception occurred. These details are also available through the\n``sys.exc_info()`` function, which returns a tuple ``(exc_type,\nexc_value, exc_traceback)``.  Use of the corresponding variables is\ndeprecated in favor of this function, since their use is unsafe in a\nthreaded program.  As of Python 1.5, the variables are restored to\ntheir previous values (before the call) when returning from a function\nthat handled an exception.\n\nThe optional ``else`` clause is executed if and when control flows off\nthe end of the ``try`` clause. [2] Exceptions in the ``else`` clause\nare not handled by the preceding ``except`` clauses.\n\nIf ``finally`` is present, it specifies a \'cleanup\' handler.  The\n``try`` clause is executed, including any ``except`` and ``else``\nclauses.  If an exception occurs in any of the clauses and is not\nhandled, the exception is temporarily saved. The ``finally`` clause is\nexecuted.  If there is a saved exception, it is re-raised at the end\nof the ``finally`` clause. If the ``finally`` clause raises another\nexception or executes a ``return`` or ``break`` statement, the saved\nexception is discarded:\n\n   def f():\n       try:\n           1/0\n       finally:\n           return 42\n\n   >>> f()\n   42\n\nThe exception information is not available to the program during\nexecution of the ``finally`` clause.\n\nWhen a ``return``, ``break`` or ``continue`` statement is executed in\nthe ``try`` suite of a ``try``...``finally`` statement, the\n``finally`` clause is also executed \'on the way out.\' A ``continue``\nstatement is illegal in the ``finally`` clause. (The reason is a\nproblem with the current implementation --- this restriction may be\nlifted in the future).\n\nAdditional information on exceptions can be found in section\n*Exceptions*, and information on using the ``raise`` statement to\ngenerate exceptions may be found in section *The raise statement*.\n\n\nThe ``with`` statement\n======================\n\nNew in version 2.5.\n\nThe ``with`` statement is used to wrap the execution of a block with\nmethods defined by a context manager (see section *With Statement\nContext Managers*). This allows common\n``try``...``except``...``finally`` usage patterns to be encapsulated\nfor convenient reuse.\n\n   with_stmt ::= "with" with_item ("," with_item)* ":" suite\n   with_item ::= expression ["as" target]\n\nThe execution of the ``with`` statement with one "item" proceeds as\nfollows:\n\n1. The context expression (the expression given in the ``with_item``)\n   is evaluated to obtain a context manager.\n\n2. The context manager\'s ``__exit__()`` is loaded for later use.\n\n3. The context manager\'s ``__enter__()`` method is invoked.\n\n4. If a target was included in the ``with`` statement, the return\n   value from ``__enter__()`` is assigned to it.\n\n   Note: The ``with`` statement guarantees that if the ``__enter__()``\n     method returns without an error, then ``__exit__()`` will always\n     be called. Thus, if an error occurs during the assignment to the\n     target list, it will be treated the same as an error occurring\n     within the suite would be. See step 6 below.\n\n5. The suite is executed.\n\n6. The context manager\'s ``__exit__()`` method is invoked. If an\n   exception caused the suite to be exited, its type, value, and\n   traceback are passed as arguments to ``__exit__()``. Otherwise,\n   three ``None`` arguments are supplied.\n\n   If the suite was exited due to an exception, and the return value\n   from the ``__exit__()`` method was false, the exception is\n   reraised. If the return value was true, the exception is\n   suppressed, and execution continues with the statement following\n   the ``with`` statement.\n\n   If the suite was exited for any reason other than an exception, the\n   return value from ``__exit__()`` is ignored, and execution proceeds\n   at the normal location for the kind of exit that was taken.\n\nWith more than one item, the context managers are processed as if\nmultiple ``with`` statements were nested:\n\n   with A() as a, B() as b:\n       suite\n\nis equivalent to\n\n   with A() as a:\n       with B() as b:\n           suite\n\nNote: In Python 2.5, the ``with`` statement is only allowed when the\n  ``with_statement`` feature has been enabled.  It is always enabled\n  in Python 2.6.\n\nChanged in version 2.7: Support for multiple context expressions.\n\nSee also:\n\n   **PEP 0343** - The "with" statement\n      The specification, background, and examples for the Python\n      ``with`` statement.\n\n\nFunction definitions\n====================\n\nA function definition defines a user-defined function object (see\nsection *The standard type hierarchy*):\n\n   decorated      ::= decorators (classdef | funcdef)\n   decorators     ::= decorator+\n   decorator      ::= "@" dotted_name ["(" [argument_list [","]] ")"] NEWLINE\n   funcdef        ::= "def" funcname "(" [parameter_list] ")" ":" suite\n   dotted_name    ::= identifier ("." identifier)*\n   parameter_list ::= (defparameter ",")*\n                      (  "*" identifier ["," "**" identifier]\n                      | "**" identifier\n                      | defparameter [","] )\n   defparameter   ::= parameter ["=" expression]\n   sublist        ::= parameter ("," parameter)* [","]\n   parameter      ::= identifier | "(" sublist ")"\n   funcname       ::= identifier\n\nA function definition is an executable statement.  Its execution binds\nthe function name in the current local namespace to a function object\n(a wrapper around the executable code for the function).  This\nfunction object contains a reference to the current global namespace\nas the global namespace to be used when the function is called.\n\nThe function definition does not execute the function body; this gets\nexecuted only when the function is called. [3]\n\nA function definition may be wrapped by one or more *decorator*\nexpressions. Decorator expressions are evaluated when the function is\ndefined, in the scope that contains the function definition.  The\nresult must be a callable, which is invoked with the function object\nas the only argument. The returned value is bound to the function name\ninstead of the function object.  Multiple decorators are applied in\nnested fashion. For example, the following code:\n\n   @f1(arg)\n   @f2\n   def func(): pass\n\nis equivalent to:\n\n   def func(): pass\n   func = f1(arg)(f2(func))\n\nWhen one or more top-level *parameters* have the form *parameter*\n``=`` *expression*, the function is said to have "default parameter\nvalues."  For a parameter with a default value, the corresponding\n*argument* may be omitted from a call, in which case the parameter\'s\ndefault value is substituted.  If a parameter has a default value, all\nfollowing parameters must also have a default value --- this is a\nsyntactic restriction that is not expressed by the grammar.\n\n**Default parameter values are evaluated when the function definition\nis executed.**  This means that the expression is evaluated once, when\nthe function is defined, and that the same "pre-computed" value is\nused for each call.  This is especially important to understand when a\ndefault parameter is a mutable object, such as a list or a dictionary:\nif the function modifies the object (e.g. by appending an item to a\nlist), the default value is in effect modified. This is generally not\nwhat was intended.  A way around this  is to use ``None`` as the\ndefault, and explicitly test for it in the body of the function, e.g.:\n\n   def whats_on_the_telly(penguin=None):\n       if penguin is None:\n           penguin = []\n       penguin.append("property of the zoo")\n       return penguin\n\nFunction call semantics are described in more detail in section\n*Calls*. A function call always assigns values to all parameters\nmentioned in the parameter list, either from position arguments, from\nkeyword arguments, or from default values.  If the form\n"``*identifier``" is present, it is initialized to a tuple receiving\nany excess positional parameters, defaulting to the empty tuple.  If\nthe form "``**identifier``" is present, it is initialized to a new\ndictionary receiving any excess keyword arguments, defaulting to a new\nempty dictionary.\n\nIt is also possible to create anonymous functions (functions not bound\nto a name), for immediate use in expressions.  This uses lambda\nexpressions, described in section *Lambdas*.  Note that the lambda\nexpression is merely a shorthand for a simplified function definition;\na function defined in a "``def``" statement can be passed around or\nassigned to another name just like a function defined by a lambda\nexpression.  The "``def``" form is actually more powerful since it\nallows the execution of multiple statements.\n\n**Programmer\'s note:** Functions are first-class objects.  A "``def``"\nform executed inside a function definition defines a local function\nthat can be returned or passed around.  Free variables used in the\nnested function can access the local variables of the function\ncontaining the def.  See section *Naming and binding* for details.\n\n\nClass definitions\n=================\n\nA class definition defines a class object (see section *The standard\ntype hierarchy*):\n\n   classdef    ::= "class" classname [inheritance] ":" suite\n   inheritance ::= "(" [expression_list] ")"\n   classname   ::= identifier\n\nA class definition is an executable statement.  It first evaluates the\ninheritance list, if present.  Each item in the inheritance list\nshould evaluate to a class object or class type which allows\nsubclassing.  The class\'s suite is then executed in a new execution\nframe (see section *Naming and binding*), using a newly created local\nnamespace and the original global namespace. (Usually, the suite\ncontains only function definitions.)  When the class\'s suite finishes\nexecution, its execution frame is discarded but its local namespace is\nsaved. [4] A class object is then created using the inheritance list\nfor the base classes and the saved local namespace for the attribute\ndictionary.  The class name is bound to this class object in the\noriginal local namespace.\n\n**Programmer\'s note:** Variables defined in the class definition are\nclass variables; they are shared by all instances.  To create instance\nvariables, they can be set in a method with ``self.name = value``.\nBoth class and instance variables are accessible through the notation\n"``self.name``", and an instance variable hides a class variable with\nthe same name when accessed in this way. Class variables can be used\nas defaults for instance variables, but using mutable values there can\nlead to unexpected results.  For *new-style class*es, descriptors can\nbe used to create instance variables with different implementation\ndetails.\n\nClass definitions, like function definitions, may be wrapped by one or\nmore *decorator* expressions.  The evaluation rules for the decorator\nexpressions are the same as for functions.  The result must be a class\nobject, which is then bound to the class name.\n\n-[ Footnotes ]-\n\n[1] The exception is propagated to the invocation stack unless there\n    is a ``finally`` clause which happens to raise another exception.\n    That new exception causes the old one to be lost.\n\n[2] Currently, control "flows off the end" except in the case of an\n    exception or the execution of a ``return``, ``continue``, or\n    ``break`` statement.\n\n[3] A string literal appearing as the first statement in the function\n    body is transformed into the function\'s ``__doc__`` attribute and\n    therefore the function\'s *docstring*.\n\n[4] A string literal appearing as the first statement in the class\n    body is transformed into the namespace\'s ``__doc__`` item and\n    therefore the class\'s *docstring*.\n',
- 'context-managers': '\nWith Statement Context Managers\n*******************************\n\nNew in version 2.5.\n\nA *context manager* is an object that defines the runtime context to\nbe established when executing a ``with`` statement. The context\nmanager handles the entry into, and the exit from, the desired runtime\ncontext for the execution of the block of code.  Context managers are\nnormally invoked using the ``with`` statement (described in section\n*The with statement*), but can also be used by directly invoking their\nmethods.\n\nTypical uses of context managers include saving and restoring various\nkinds of global state, locking and unlocking resources, closing opened\nfiles, etc.\n\nFor more information on context managers, see *Context Manager Types*.\n\nobject.__enter__(self)\n\n   Enter the runtime context related to this object. The ``with``\n   statement will bind this method\'s return value to the target(s)\n   specified in the ``as`` clause of the statement, if any.\n\nobject.__exit__(self, exc_type, exc_value, traceback)\n\n   Exit the runtime context related to this object. The parameters\n   describe the exception that caused the context to be exited. If the\n   context was exited without an exception, all three arguments will\n   be ``None``.\n\n   If an exception is supplied, and the method wishes to suppress the\n   exception (i.e., prevent it from being propagated), it should\n   return a true value. Otherwise, the exception will be processed\n   normally upon exit from this method.\n\n   Note that ``__exit__()`` methods should not reraise the passed-in\n   exception; this is the caller\'s responsibility.\n\nSee also:\n\n   **PEP 0343** - The "with" statement\n      The specification, background, and examples for the Python\n      ``with`` statement.\n',
- 'continue': '\nThe ``continue`` statement\n**************************\n\n   continue_stmt ::= "continue"\n\n``continue`` may only occur syntactically nested in a ``for`` or\n``while`` loop, but not nested in a function or class definition or\n``finally`` clause within that loop.  It continues with the next cycle\nof the nearest enclosing loop.\n\nWhen ``continue`` passes control out of a ``try`` statement with a\n``finally`` clause, that ``finally`` clause is executed before really\nstarting the next loop cycle.\n',
- 'conversions': '\nArithmetic conversions\n**********************\n\nWhen a description of an arithmetic operator below uses the phrase\n"the numeric arguments are converted to a common type," the arguments\nare coerced using the coercion rules listed at  *Coercion rules*.  If\nboth arguments are standard numeric types, the following coercions are\napplied:\n\n* If either argument is a complex number, the other is converted to\n  complex;\n\n* otherwise, if either argument is a floating point number, the other\n  is converted to floating point;\n\n* otherwise, if either argument is a long integer, the other is\n  converted to long integer;\n\n* otherwise, both must be plain integers and no conversion is\n  necessary.\n\nSome additional rules apply for certain operators (e.g., a string left\nargument to the \'%\' operator). Extensions can define their own\ncoercions.\n',
- 'customization': '\nBasic customization\n*******************\n\nobject.__new__(cls[, ...])\n\n   Called to create a new instance of class *cls*.  ``__new__()`` is a\n   static method (special-cased so you need not declare it as such)\n   that takes the class of which an instance was requested as its\n   first argument.  The remaining arguments are those passed to the\n   object constructor expression (the call to the class).  The return\n   value of ``__new__()`` should be the new object instance (usually\n   an instance of *cls*).\n\n   Typical implementations create a new instance of the class by\n   invoking the superclass\'s ``__new__()`` method using\n   ``super(currentclass, cls).__new__(cls[, ...])`` with appropriate\n   arguments and then modifying the newly-created instance as\n   necessary before returning it.\n\n   If ``__new__()`` returns an instance of *cls*, then the new\n   instance\'s ``__init__()`` method will be invoked like\n   ``__init__(self[, ...])``, where *self* is the new instance and the\n   remaining arguments are the same as were passed to ``__new__()``.\n\n   If ``__new__()`` does not return an instance of *cls*, then the new\n   instance\'s ``__init__()`` method will not be invoked.\n\n   ``__new__()`` is intended mainly to allow subclasses of immutable\n   types (like int, str, or tuple) to customize instance creation.  It\n   is also commonly overridden in custom metaclasses in order to\n   customize class creation.\n\nobject.__init__(self[, ...])\n\n   Called when the instance is created.  The arguments are those\n   passed to the class constructor expression.  If a base class has an\n   ``__init__()`` method, the derived class\'s ``__init__()`` method,\n   if any, must explicitly call it to ensure proper initialization of\n   the base class part of the instance; for example:\n   ``BaseClass.__init__(self, [args...])``.  As a special constraint\n   on constructors, no value may be returned; doing so will cause a\n   ``TypeError`` to be raised at runtime.\n\nobject.__del__(self)\n\n   Called when the instance is about to be destroyed.  This is also\n   called a destructor.  If a base class has a ``__del__()`` method,\n   the derived class\'s ``__del__()`` method, if any, must explicitly\n   call it to ensure proper deletion of the base class part of the\n   instance.  Note that it is possible (though not recommended!) for\n   the ``__del__()`` method to postpone destruction of the instance by\n   creating a new reference to it.  It may then be called at a later\n   time when this new reference is deleted.  It is not guaranteed that\n   ``__del__()`` methods are called for objects that still exist when\n   the interpreter exits.\n\n   Note: ``del x`` doesn\'t directly call ``x.__del__()`` --- the former\n     decrements the reference count for ``x`` by one, and the latter\n     is only called when ``x``\'s reference count reaches zero.  Some\n     common situations that may prevent the reference count of an\n     object from going to zero include: circular references between\n     objects (e.g., a doubly-linked list or a tree data structure with\n     parent and child pointers); a reference to the object on the\n     stack frame of a function that caught an exception (the traceback\n     stored in ``sys.exc_traceback`` keeps the stack frame alive); or\n     a reference to the object on the stack frame that raised an\n     unhandled exception in interactive mode (the traceback stored in\n     ``sys.last_traceback`` keeps the stack frame alive).  The first\n     situation can only be remedied by explicitly breaking the cycles;\n     the latter two situations can be resolved by storing ``None`` in\n     ``sys.exc_traceback`` or ``sys.last_traceback``.  Circular\n     references which are garbage are detected when the option cycle\n     detector is enabled (it\'s on by default), but can only be cleaned\n     up if there are no Python-level ``__del__()`` methods involved.\n     Refer to the documentation for the ``gc`` module for more\n     information about how ``__del__()`` methods are handled by the\n     cycle detector, particularly the description of the ``garbage``\n     value.\n\n   Warning: Due to the precarious circumstances under which ``__del__()``\n     methods are invoked, exceptions that occur during their execution\n     are ignored, and a warning is printed to ``sys.stderr`` instead.\n     Also, when ``__del__()`` is invoked in response to a module being\n     deleted (e.g., when execution of the program is done), other\n     globals referenced by the ``__del__()`` method may already have\n     been deleted or in the process of being torn down (e.g. the\n     import machinery shutting down).  For this reason, ``__del__()``\n     methods should do the absolute minimum needed to maintain\n     external invariants.  Starting with version 1.5, Python\n     guarantees that globals whose name begins with a single\n     underscore are deleted from their module before other globals are\n     deleted; if no other references to such globals exist, this may\n     help in assuring that imported modules are still available at the\n     time when the ``__del__()`` method is called.\n\n   See also the *-R* command-line option.\n\nobject.__repr__(self)\n\n   Called by the ``repr()`` built-in function and by string\n   conversions (reverse quotes) to compute the "official" string\n   representation of an object.  If at all possible, this should look\n   like a valid Python expression that could be used to recreate an\n   object with the same value (given an appropriate environment).  If\n   this is not possible, a string of the form ``<...some useful\n   description...>`` should be returned.  The return value must be a\n   string object. If a class defines ``__repr__()`` but not\n   ``__str__()``, then ``__repr__()`` is also used when an "informal"\n   string representation of instances of that class is required.\n\n   This is typically used for debugging, so it is important that the\n   representation is information-rich and unambiguous.\n\nobject.__str__(self)\n\n   Called by the ``str()`` built-in function and by the ``print``\n   statement to compute the "informal" string representation of an\n   object.  This differs from ``__repr__()`` in that it does not have\n   to be a valid Python expression: a more convenient or concise\n   representation may be used instead. The return value must be a\n   string object.\n\nobject.__lt__(self, other)\nobject.__le__(self, other)\nobject.__eq__(self, other)\nobject.__ne__(self, other)\nobject.__gt__(self, other)\nobject.__ge__(self, other)\n\n   New in version 2.1.\n\n   These are the so-called "rich comparison" methods, and are called\n   for comparison operators in preference to ``__cmp__()`` below. The\n   correspondence between operator symbols and method names is as\n   follows: ``x<y`` calls ``x.__lt__(y)``, ``x<=y`` calls\n   ``x.__le__(y)``, ``x==y`` calls ``x.__eq__(y)``, ``x!=y`` and\n   ``x<>y`` call ``x.__ne__(y)``, ``x>y`` calls ``x.__gt__(y)``, and\n   ``x>=y`` calls ``x.__ge__(y)``.\n\n   A rich comparison method may return the singleton\n   ``NotImplemented`` if it does not implement the operation for a\n   given pair of arguments. By convention, ``False`` and ``True`` are\n   returned for a successful comparison. However, these methods can\n   return any value, so if the comparison operator is used in a\n   Boolean context (e.g., in the condition of an ``if`` statement),\n   Python will call ``bool()`` on the value to determine if the result\n   is true or false.\n\n   There are no implied relationships among the comparison operators.\n   The truth of ``x==y`` does not imply that ``x!=y`` is false.\n   Accordingly, when defining ``__eq__()``, one should also define\n   ``__ne__()`` so that the operators will behave as expected.  See\n   the paragraph on ``__hash__()`` for some important notes on\n   creating *hashable* objects which support custom comparison\n   operations and are usable as dictionary keys.\n\n   There are no swapped-argument versions of these methods (to be used\n   when the left argument does not support the operation but the right\n   argument does); rather, ``__lt__()`` and ``__gt__()`` are each\n   other\'s reflection, ``__le__()`` and ``__ge__()`` are each other\'s\n   reflection, and ``__eq__()`` and ``__ne__()`` are their own\n   reflection.\n\n   Arguments to rich comparison methods are never coerced.\n\n   To automatically generate ordering operations from a single root\n   operation, see ``functools.total_ordering()``.\n\nobject.__cmp__(self, other)\n\n   Called by comparison operations if rich comparison (see above) is\n   not defined.  Should return a negative integer if ``self < other``,\n   zero if ``self == other``, a positive integer if ``self > other``.\n   If no ``__cmp__()``, ``__eq__()`` or ``__ne__()`` operation is\n   defined, class instances are compared by object identity\n   ("address").  See also the description of ``__hash__()`` for some\n   important notes on creating *hashable* objects which support custom\n   comparison operations and are usable as dictionary keys. (Note: the\n   restriction that exceptions are not propagated by ``__cmp__()`` has\n   been removed since Python 1.5.)\n\nobject.__rcmp__(self, other)\n\n   Changed in version 2.1: No longer supported.\n\nobject.__hash__(self)\n\n   Called by built-in function ``hash()`` and for operations on\n   members of hashed collections including ``set``, ``frozenset``, and\n   ``dict``.  ``__hash__()`` should return an integer.  The only\n   required property is that objects which compare equal have the same\n   hash value; it is advised to somehow mix together (e.g. using\n   exclusive or) the hash values for the components of the object that\n   also play a part in comparison of objects.\n\n   If a class does not define a ``__cmp__()`` or ``__eq__()`` method\n   it should not define a ``__hash__()`` operation either; if it\n   defines ``__cmp__()`` or ``__eq__()`` but not ``__hash__()``, its\n   instances will not be usable in hashed collections.  If a class\n   defines mutable objects and implements a ``__cmp__()`` or\n   ``__eq__()`` method, it should not implement ``__hash__()``, since\n   hashable collection implementations require that a object\'s hash\n   value is immutable (if the object\'s hash value changes, it will be\n   in the wrong hash bucket).\n\n   User-defined classes have ``__cmp__()`` and ``__hash__()`` methods\n   by default; with them, all objects compare unequal (except with\n   themselves) and ``x.__hash__()`` returns ``id(x)``.\n\n   Classes which inherit a ``__hash__()`` method from a parent class\n   but change the meaning of ``__cmp__()`` or ``__eq__()`` such that\n   the hash value returned is no longer appropriate (e.g. by switching\n   to a value-based concept of equality instead of the default\n   identity based equality) can explicitly flag themselves as being\n   unhashable by setting ``__hash__ = None`` in the class definition.\n   Doing so means that not only will instances of the class raise an\n   appropriate ``TypeError`` when a program attempts to retrieve their\n   hash value, but they will also be correctly identified as\n   unhashable when checking ``isinstance(obj, collections.Hashable)``\n   (unlike classes which define their own ``__hash__()`` to explicitly\n   raise ``TypeError``).\n\n   Changed in version 2.5: ``__hash__()`` may now also return a long\n   integer object; the 32-bit integer is then derived from the hash of\n   that object.\n\n   Changed in version 2.6: ``__hash__`` may now be set to ``None`` to\n   explicitly flag instances of a class as unhashable.\n\nobject.__nonzero__(self)\n\n   Called to implement truth value testing and the built-in operation\n   ``bool()``; should return ``False`` or ``True``, or their integer\n   equivalents ``0`` or ``1``.  When this method is not defined,\n   ``__len__()`` is called, if it is defined, and the object is\n   considered true if its result is nonzero. If a class defines\n   neither ``__len__()`` nor ``__nonzero__()``, all its instances are\n   considered true.\n\nobject.__unicode__(self)\n\n   Called to implement ``unicode()`` built-in; should return a Unicode\n   object. When this method is not defined, string conversion is\n   attempted, and the result of string conversion is converted to\n   Unicode using the system default encoding.\n',
- 'debugger': '\n``pdb`` --- The Python Debugger\n*******************************\n\nThe module ``pdb`` defines an interactive source code debugger for\nPython programs.  It supports setting (conditional) breakpoints and\nsingle stepping at the source line level, inspection of stack frames,\nsource code listing, and evaluation of arbitrary Python code in the\ncontext of any stack frame.  It also supports post-mortem debugging\nand can be called under program control.\n\nThe debugger is extensible --- it is actually defined as the class\n``Pdb``. This is currently undocumented but easily understood by\nreading the source.  The extension interface uses the modules ``bdb``\nand ``cmd``.\n\nThe debugger\'s prompt is ``(Pdb)``. Typical usage to run a program\nunder control of the debugger is:\n\n   >>> import pdb\n   >>> import mymodule\n   >>> pdb.run(\'mymodule.test()\')\n   > <string>(0)?()\n   (Pdb) continue\n   > <string>(1)?()\n   (Pdb) continue\n   NameError: \'spam\'\n   > <string>(1)?()\n   (Pdb)\n\n``pdb.py`` can also be invoked as a script to debug other scripts.\nFor example:\n\n   python -m pdb myscript.py\n\nWhen invoked as a script, pdb will automatically enter post-mortem\ndebugging if the program being debugged exits abnormally. After post-\nmortem debugging (or after normal exit of the program), pdb will\nrestart the program. Automatic restarting preserves pdb\'s state (such\nas breakpoints) and in most cases is more useful than quitting the\ndebugger upon program\'s exit.\n\nNew in version 2.4: Restarting post-mortem behavior added.\n\nThe typical usage to break into the debugger from a running program is\nto insert\n\n   import pdb; pdb.set_trace()\n\nat the location you want to break into the debugger.  You can then\nstep through the code following this statement, and continue running\nwithout the debugger using the ``c`` command.\n\nThe typical usage to inspect a crashed program is:\n\n   >>> import pdb\n   >>> import mymodule\n   >>> mymodule.test()\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in ?\n     File "./mymodule.py", line 4, in test\n       test2()\n     File "./mymodule.py", line 3, in test2\n       print spam\n   NameError: spam\n   >>> pdb.pm()\n   > ./mymodule.py(3)test2()\n   -> print spam\n   (Pdb)\n\nThe module defines the following functions; each enters the debugger\nin a slightly different way:\n\npdb.run(statement[, globals[, locals]])\n\n   Execute the *statement* (given as a string) under debugger control.\n   The debugger prompt appears before any code is executed; you can\n   set breakpoints and type ``continue``, or you can step through the\n   statement using ``step`` or ``next`` (all these commands are\n   explained below).  The optional *globals* and *locals* arguments\n   specify the environment in which the code is executed; by default\n   the dictionary of the module ``__main__`` is used.  (See the\n   explanation of the ``exec`` statement or the ``eval()`` built-in\n   function.)\n\npdb.runeval(expression[, globals[, locals]])\n\n   Evaluate the *expression* (given as a string) under debugger\n   control.  When ``runeval()`` returns, it returns the value of the\n   expression.  Otherwise this function is similar to ``run()``.\n\npdb.runcall(function[, argument, ...])\n\n   Call the *function* (a function or method object, not a string)\n   with the given arguments.  When ``runcall()`` returns, it returns\n   whatever the function call returned.  The debugger prompt appears\n   as soon as the function is entered.\n\npdb.set_trace()\n\n   Enter the debugger at the calling stack frame.  This is useful to\n   hard-code a breakpoint at a given point in a program, even if the\n   code is not otherwise being debugged (e.g. when an assertion\n   fails).\n\npdb.post_mortem([traceback])\n\n   Enter post-mortem debugging of the given *traceback* object.  If no\n   *traceback* is given, it uses the one of the exception that is\n   currently being handled (an exception must be being handled if the\n   default is to be used).\n\npdb.pm()\n\n   Enter post-mortem debugging of the traceback found in\n   ``sys.last_traceback``.\n\nThe ``run*`` functions and ``set_trace()`` are aliases for\ninstantiating the ``Pdb`` class and calling the method of the same\nname.  If you want to access further features, you have to do this\nyourself:\n\nclass class pdb.Pdb(completekey=\'tab\', stdin=None, stdout=None, skip=None)\n\n   ``Pdb`` is the debugger class.\n\n   The *completekey*, *stdin* and *stdout* arguments are passed to the\n   underlying ``cmd.Cmd`` class; see the description there.\n\n   The *skip* argument, if given, must be an iterable of glob-style\n   module name patterns.  The debugger will not step into frames that\n   originate in a module that matches one of these patterns. [1]\n\n   Example call to enable tracing with *skip*:\n\n      import pdb; pdb.Pdb(skip=[\'django.*\']).set_trace()\n\n   New in version 2.7: The *skip* argument.\n\n   run(statement[, globals[, locals]])\n   runeval(expression[, globals[, locals]])\n   runcall(function[, argument, ...])\n   set_trace()\n\n      See the documentation for the functions explained above.\n',

- 'dict': '\nDictionary displays\n*******************\n\nA dictionary display is a possibly empty series of key/datum pairs\nenclosed in curly braces:\n\n   dict_display       ::= "{" [key_datum_list | dict_comprehension] "}"\n   key_datum_list     ::= key_datum ("," key_datum)* [","]\n   key_datum          ::= expression ":" expression\n   dict_comprehension ::= expression ":" expression comp_for\n\nA dictionary display yields a new dictionary object.\n\nIf a comma-separated sequence of key/datum pairs is given, they are\nevaluated from left to right to define the entries of the dictionary:\neach key object is used as a key into the dictionary to store the\ncorresponding datum.  This means that you can specify the same key\nmultiple times in the key/datum list, and the final dictionary\'s value\nfor that key will be the last one given.\n\nA dict comprehension, in contrast to list and set comprehensions,\nneeds two expressions separated with a colon followed by the usual\n"for" and "if" clauses. When the comprehension is run, the resulting\nkey and value elements are inserted in the new dictionary in the order\nthey are produced.\n\nRestrictions on the types of the key values are listed earlier in\nsection *The standard type hierarchy*.  (To summarize, the key type\nshould be *hashable*, which excludes all mutable objects.)

- 'dynamic-features': '\nInteraction with dynamic features\n*********************************\n\nThere are several cases where Python statements are illegal when used\nin conjunction with nested scopes that contain free variables.\n\nIf a variable is referenced in an enclosing scope, it is illegal to\ndelete the name.

- 'else': '\nThe ``if`` statement\n********************\n\nThe ``if`` statement is used for conditional execution:\n\n   if_stmt ::= "if" expression ":" suite\n               ( "elif" expression ":" suite )*\n               ["else" ":" suite]\n\nIt selects exactly one of the suites by evaluating the expressions one\nby one until one is found to be true (see section *Boolean operations*\nfor the definition of true and false); then that suite is executed\n(and no other part of the ``if`` statement is executed or evaluated).\nIf all expressions are false, the suite of the ``else`` clause, if\npresent, is executed.\n',
- 'exceptions': '\nExceptions\n**********\n\nExceptions are a means of breaking out of the normal flow of control\nof a code block in order to handle errors or other exceptional\nconditions.  An exception is *raised* at the point where the error is\ndetected; it may be *handled* by the surrounding code block or by any\ncode block that directly or indirectly invoked the code block where\nthe error occurred.\n\nThe Python interpreter raises an exception when it detects a run-time\nerror (such as division by zero).  A Python program can also\nexplicitly raise an exception with the ``raise`` statement. Exception\nhandlers are specified with the ``try`` ... ``except`` statement.  The\n``finally`` clause of such a statement can be used to specify cleanup\ncode which does not handle the exception, but is executed whether an\nexception occurred or not in the preceding code.\n\nPython uses the "termination" model of error handling: an exception\nhandler can find out what happened and continue execution at an outer\nlevel, but it cannot repair the cause of the error and retry the\nfailing operation (except by re-entering the offending piece of code\nfrom the top).\n\nWhen an exception is not handled at all, the interpreter terminates\nexecution of the program, or returns to its interactive main loop.  In\neither case, it prints a stack backtrace, except when the exception is\n``SystemExit``.\n\nExceptions are identified by class instances.  The ``except`` clause\nis selected depending on the class of the instance: it must reference\nthe class of the instance or a base class thereof.  The instance can\nbe received by the handler and can carry additional information about\nthe exceptional condition.\n\nExceptions can also be identified by strings, in which case the\n``except`` clause is selected by object identity.  An arbitrary value\ncan be raised along with the identifying string which can be passed to\nthe handler.\n\nNote: Messages to exceptions are not part of the Python API.  Their\n  contents may change from one version of Python to the next without\n  warning and should not be relied on by code which will run under\n  multiple versions of the interpreter.\n\nSee also the description of the ``try`` statement in section *The try\nstatement* and ``raise`` statement in section *The raise statement*.\n\n-[ Footnotes ]-\n\n[1] This limitation occurs because the code that is executed by these\n    operations is not available at the time the module is compiled.\n',
- 'execmodel': '\nExecution model\n***************\n\n\nNaming and binding\n==================\n\n*Names* refer to objects.  Names are introduced by name binding\noperations. Each occurrence of a name in the program text refers to\nthe *binding* of that name established in the innermost function block\ncontaining the use.\n\nA *block* is a piece of Python program text that is executed as a\nunit. The following are blocks: a module, a function body, and a class\ndefinition. Each command typed interactively is a block.  A script\nfile (a file given as standard input to the interpreter or specified\non the interpreter command line the first argument) is a code block.\nA script command (a command specified on the interpreter command line\nwith the \'**-c**\' option) is a code block.  The file read by the\nbuilt-in function ``execfile()`` is a code block.  The string argument\npassed to the built-in function ``eval()`` and to the ``exec``\nstatement is a code block. The expression read and evaluated by the\nbuilt-in function ``input()`` is a code block.\n\nA code block is executed in an *execution frame*.  A frame contains\nsome administrative information (used for debugging) and determines\nwhere and how execution continues after the code block\'s execution has\ncompleted.\n\nA *scope* defines the visibility of a name within a block.  If a local\nvariable is defined in a block, its scope includes that block.  If the\ndefinition occurs in a function block, the scope extends to any blocks\ncontained within the defining one, unless a contained block introduces\na different binding for the name.  The scope of names defined in a\nclass block is limited to the class block; it does not extend to the\ncode blocks of methods -- this includes generator expressions since\nthey are implemented using a function scope.  This means that the\nfollowing will fail:\n\n   class A:\n       a = 42\n       b = list(a + i for i in range(10))\n\nWhen a name is used in a code block, it is resolved using the nearest\nenclosing scope.  The set of all such scopes visible to a code block\nis called the block\'s *environment*.\n\nIf a name is bound in a block, it is a local variable of that block.\nIf a name is bound at the module level, it is a global variable.  (The\nvariables of the module code block are local and global.)  If a\nvariable is used in a code block but not defined there, it is a *free\nvariable*.\n\nWhen a name is not found at all, a ``NameError`` exception is raised.\nIf the name refers to a local variable that has not been bound, a\n``UnboundLocalError`` exception is raised.  ``UnboundLocalError`` is a\nsubclass of ``NameError``.\n\nThe following constructs bind names: formal parameters to functions,\n``import`` statements, class and function definitions (these bind the\nclass or function name in the defining block), and targets that are\nidentifiers if occurring in an assignment, ``for`` loop header, in the\nsecond position of an ``except`` clause header or after ``as`` in a\n``with`` statement.  The ``import`` statement of the form ``from ...\nimport *`` binds all names defined in the imported module, except\nthose beginning with an underscore.  This form may only be used at the\nmodule level.\n\nA target occurring in a ``del`` statement is also considered bound for\nthis purpose (though the actual semantics are to unbind the name).  It\nis illegal to unbind a name that is referenced by an enclosing scope;\nthe compiler will report a ``SyntaxError``.\n\nEach assignment or import statement occurs within a block defined by a\nclass or function definition or at the module level (the top-level\ncode block).\n\nIf a name binding operation occurs anywhere within a code block, all\nuses of the name within the block are treated as references to the\ncurrent block.  This can lead to errors when a name is used within a\nblock before it is bound. This rule is subtle.  Python lacks\ndeclarations and allows name binding operations to occur anywhere\nwithin a code block.  The local variables of a code block can be\ndetermined by scanning the entire text of the block for name binding\noperations.\n\nIf the global statement occurs within a block, all uses of the name\nspecified in the statement refer to the binding of that name in the\ntop-level namespace. Names are resolved in the top-level namespace by\nsearching the global namespace, i.e. the namespace of the module\ncontaining the code block, and the builtins namespace, the namespace\nof the module ``__builtin__``.  The global namespace is searched\nfirst.  If the name is not found there, the builtins namespace is\nsearched.  The global statement must precede all uses of the name.\n\nThe builtins namespace associated with the execution of a code block\nis actually found by looking up the name ``__builtins__`` in its\nglobal namespace; this should be a dictionary or a module (in the\nlatter case the module\'s dictionary is used).  By default, when in the\n``__main__`` module, ``__builtins__`` is the built-in module\n``__builtin__`` (note: no \'s\'); when in any other module,\n``__builtins__`` is an alias for the dictionary of the ``__builtin__``\nmodule itself.  ``__builtins__`` can be set to a user-created\ndictionary to create a weak form of restricted execution.\n\n**CPython implementation detail:** Users should not touch\n``__builtins__``; it is strictly an implementation detail.  Users\nwanting to override values in the builtins namespace should ``import``\nthe ``__builtin__`` (no \'s\') module and modify its attributes\nappropriately.\n\nThe namespace for a module is automatically created the first time a\nmodule is imported.  The main module for a script is always called\n``__main__``.\n\nThe ``global`` statement has the same scope as a name binding\noperation in the same block.  If the nearest enclosing scope for a\nfree variable contains a global statement, the free variable is\ntreated as a global.\n\nA class definition is an executable statement that may use and define\nnames. These references follow the normal rules for name resolution.\nThe namespace of the class definition becomes the attribute dictionary\nof the class.  Names defined at the class scope are not visible in\nmethods.\n\n\nInteraction with dynamic features\n---------------------------------\n\nThere are several cases where Python statements are illegal when used\nin conjunction with nested scopes that contain free variables.\n\nIf a variable is referenced in an enclosing scope, it is illegal to\ndelete the name.  An error will be reported at compile time.\n\nIf the wild card form of import --- ``import *`` --- is used in a\nfunction and the function contains or is a nested block with free\nvariables, the compiler will raise a ``SyntaxError``.\n\nIf ``exec`` is used in a function and the function contains or is a\nnested block with free variables, the compiler will raise a\n``SyntaxError`` unless the exec explicitly specifies the local\nnamespace for the ``exec``.  (In other words, ``exec obj`` would be\nillegal, but ``exec obj in ns`` would be legal.)\n\nThe ``eval()``, ``execfile()``, and ``input()`` functions and the\n``exec`` statement do not have access to the full environment for\nresolving names.  Names may be resolved in the local and global\nnamespaces of the caller.  Free variables are not resolved in the\nnearest enclosing namespace, but in the global namespace. [1] The\n``exec`` statement and the ``eval()`` and ``execfile()`` functions\nhave optional arguments to override the global and local namespace.\nIf only one namespace is specified, it is used for both.\n\n\nExceptions\n==========\n\nExceptions are a means of breaking out of the normal flow of control\nof a code block in order to handle errors or other exceptional\nconditions.  An exception is *raised* at the point where the error is\ndetected; it may be *handled* by the surrounding code block or by any\ncode block that directly or indirectly invoked the code block where\nthe error occurred.\n\nThe Python interpreter raises an exception when it detects a run-time\nerror (such as division by zero).  A Python program can also\nexplicitly raise an exception with the ``raise`` statement. Exception\nhandlers are specified with the ``try`` ... ``except`` statement.  The\n``finally`` clause of such a statement can be used to specify cleanup\ncode which does not handle the exception, but is executed whether an\nexception occurred or not in the preceding code.\n\nPython uses the "termination" model of error handling: an exception\nhandler can find out what happened and continue execution at an outer\nlevel, but it cannot repair the cause of the error and retry the\nfailing operation (except by re-entering the offending piece of code\nfrom the top).\n\nWhen an exception is not handled at all, the interpreter terminates\nexecution of the program, or returns to its interactive main loop.

- 'exprlists': '\nExpression lists\n****************\n\n   expression_list ::= expression ( "," expression )* [","]\n\nAn expression list containing at least one comma yields a tuple.  The\nlength of the tuple is the number of expressions in the list.  The\nexpressions are evaluated from left to right.\n\nThe trailing comma is required only to create a single tuple (a.k.a. a\n*singleton*); it is optional in all other cases.  A single expression\nwithout a trailing comma doesn\'t create a tuple, but rather yields the\nvalue of that expression. (To create an empty tuple, use an empty pair\nof parentheses: ``()``.)\n',
- 'floating': '\nFloating point literals\n***********************\n\nFloating point literals are described by the following lexical\ndefinitions:\n\n   floatnumber   ::= pointfloat | exponentfloat\n   pointfloat    ::= [intpart] fraction | intpart "."\n   exponentfloat ::= (intpart | pointfloat) exponent\n   intpart       ::= digit+\n   fraction      ::= "." digit+\n   exponent      ::= ("e" | "E") ["+" | "-"] digit+\n\nNote that the integer and exponent parts of floating point numbers can\nlook like octal integers, but are interpreted using radix 10.  For\nexample, ``077e010`` is legal, and denotes the same number as\n``77e10``. The allowed range of floating point literals is\nimplementation-dependent. Some examples of floating point literals:\n\n   3.14    10.    .001    1e100    3.14e-10    0e0\n\nNote that numeric literals do not include a sign; a phrase like ``-1``\nis actually an expression composed of the unary operator ``-`` and the\nliteral ``1``.\n',
- 'for': '\nThe ``for`` statement\n*********************\n\nThe ``for`` statement is used to iterate over the elements of a\nsequence (such as a string, tuple or list) or other iterable object:\n\n   for_stmt ::= "for" target_list "in" expression_list ":" suite\n                ["else" ":" suite]\n\nThe expression list is evaluated once; it should yield an iterable\nobject.  An iterator is created for the result of the\n``expression_list``.  The suite is then executed once for each item\nprovided by the iterator, in the order of ascending indices.  Each\nitem in turn is assigned to the target list using the standard rules\nfor assignments, and then the suite is executed.  When the items are\nexhausted (which is immediately when the sequence is empty), the suite\nin the ``else`` clause, if present, is executed, and the loop\nterminates.\n\nA ``break`` statement executed in the first suite terminates the loop\nwithout executing the ``else`` clause\'s suite.  A ``continue``\nstatement executed in the first suite skips the rest of the suite and\ncontinues with the next item, or with the ``else`` clause if there was\nno next item.\n\nThe suite may assign to the variable(s) in the target list; this does\nnot affect the next item assigned to it.\n\nThe target list is not deleted when the loop is finished, but if the\nsequence is empty, it will not have been assigned to at all by the\nloop.  Hint: the built-in function ``range()`` returns a sequence of\nintegers suitable to emulate the effect of Pascal\'s ``for i := a to b\ndo``; e.g., ``range(3)`` returns the list ``[0, 1, 2]``.\n\nNote: There is a subtlety when the sequence is being modified by the loop\n  (this can only occur for mutable sequences, i.e. lists). An internal\n  counter is used to keep track of which item is used next, and this\n  is incremented on each iteration.  When this counter has reached the\n  length of the sequence the loop terminates.  This means that if the\n  suite deletes the current (or a previous) item from the sequence,\n  the next item will be skipped (since it gets the index of the\n  current item which has already been treated).  Likewise, if the\n  suite inserts an item in the sequence before the current item, the\n  current item will be treated again the next time through the loop.\n  This can lead to nasty bugs that can be avoided by making a\n  temporary copy using a slice of the whole sequence, e.g.,\n\n     for x in a[:]:\n         if x < 0: a.remove(x)\n',
- 'formatstrings': '\nFormat String Syntax\n********************\n\nThe ``str.format()`` method and the ``Formatter`` class share the same\nsyntax for format strings (although in the case of ``Formatter``,\nsubclasses can define their own format string syntax).\n\nFormat strings contain "replacement fields" surrounded by curly braces\n``{}``. Anything that is not contained in braces is considered literal\ntext, which is copied unchanged to the output.  If you need to include\na brace character in the literal text, it can be escaped by doubling:\n``{{`` and ``}}``.\n\nThe grammar for a replacement field is as follows:\n\n      replacement_field ::= "{" [field_name] ["!" conversion] [":" format_spec] "}"\n      field_name        ::= arg_name ("." attribute_name | "[" element_index "]")*\n      arg_name          ::= [identifier | integer]\n      attribute_name    ::= identifier\n      element_index     ::= integer | index_string\n      index_string      ::= <any source character except "]"> +\n      conversion        ::= "r" | "s"\n      format_spec       ::= <described in the next section>\n\nIn less formal terms, the replacement field can start with a\n*field_name* that specifies the object whose value is to be formatted\nand inserted into the output instead of the replacement field. The\n*field_name* is optionally followed by a  *conversion* field, which is\npreceded by an exclamation point ``\'!\'``, and a *format_spec*, which\nis preceded by a colon ``\':\'``.  These specify a non-default format\nfor the replacement value.\n\nSee also the *Format Specification Mini-Language* section.\n\nThe *field_name* itself begins with an *arg_name* that is either a\nnumber or a keyword.  If it\'s a number, it refers to a positional\nargument, and if it\'s a keyword, it refers to a named keyword\nargument.  If the numerical arg_names in a format string are 0, 1, 2,\n... in sequence, they can all be omitted (not just some) and the\nnumbers 0, 1, 2, ... will be automatically inserted in that order.\nBecause *arg_name* is not quote-delimited, it is not possible to\nspecify arbitrary dictionary keys (e.g., the strings ``\'10\'`` or\n``\':-]\'``) within a format string. The *arg_name* can be followed by\nany number of index or attribute expressions. An expression of the\nform ``\'.name\'`` selects the named attribute using ``getattr()``,\nwhile an expression of the form ``\'[index]\'`` does an index lookup\nusing ``__getitem__()``.\n\nChanged in version 2.7: The positional argument specifiers can be\nomitted, so ``\'{} {}\'`` is equivalent to ``\'{0} {1}\'``.\n\nSome simple format string examples:\n\n   "First, thou shalt count to {0}" # References first positional argument\n   "Bring me a {}"                  # Implicitly references the first positional argument\n   "From {} to {}"                  # Same as "From {0} to {1}"\n   "My quest is {name}"             # References keyword argument \'name\'\n   "Weight in tons {0.weight}"      # \'weight\' attribute of first positional arg\n   "Units destroyed: {players[0]}"  # First element of keyword argument \'players\'.\n\nThe *conversion* field causes a type coercion before formatting.\nNormally, the job of formatting a value is done by the\n``__format__()`` method of the value itself.  However, in some cases\nit is desirable to force a type to be formatted as a string,\noverriding its own definition of formatting.  By converting the value\nto a string before calling ``__format__()``, the normal formatting\nlogic is bypassed.\n\nTwo conversion flags are currently supported: ``\'!s\'`` which calls\n``str()`` on the value, and ``\'!r\'`` which calls ``repr()``.\n\nSome examples:\n\n   "Harold\'s a clever {0!s}"        # Calls str() on the argument first\n   "Bring out the holy {name!r}"    # Calls repr() on the argument first\n\nThe *format_spec* field contains a specification of how the value\nshould be presented, including such details as field width, alignment,\npadding, decimal precision and so on.  Each value type can define its\nown "formatting mini-language" or interpretation of the *format_spec*.\n\nMost built-in types support a common formatting mini-language, which\nis described in the next section.\n\nA *format_spec* field can also include nested replacement fields\nwithin it. These nested replacement fields can contain only a field\nname; conversion flags and format specifications are not allowed.  The\nreplacement fields within the format_spec are substituted before the\n*format_spec* string is interpreted. This allows the formatting of a\nvalue to be dynamically specified.\n\nSee the *Format examples* section for some examples.\n\n\nFormat Specification Mini-Language\n==================================\n\n"Format specifications" are used within replacement fields contained\nwithin a format string to define how individual values are presented\n(see *Format String Syntax*).  They can also be passed directly to the\nbuilt-in ``format()`` function.  Each formattable type may define how\nthe format specification is to be interpreted.\n\nMost built-in types implement the following options for format\nspecifications, although some of the formatting options are only\nsupported by the numeric types.\n\nA general convention is that an empty format string (``""``) produces\nthe same result as if you had called ``str()`` on the value. A non-\nempty format string typically modifies the result.\n\nThe general form of a *standard format specifier* is:\n\n   format_spec ::= [[fill]align][sign][#][0][width][,][.precision][type]\n   fill        ::= <any character>\n   align       ::= "<" | ">" | "=" | "^"\n   sign        ::= "+" | "-" | " "\n   width       ::= integer\n   precision   ::= integer\n   type        ::= "b" | "c" | "d" | "e" | "E" | "f" | "F" | "g" | "G" | "n" | "o" | "s" | "x" | "X" | "%"\n\nIf a valid *align* value is specified, it can be preceeded by a *fill*\ncharacter that can be any character and defaults to a space if\nomitted. Note that it is not possible to use ``{`` and ``}`` as *fill*\nchar while using the ``str.format()`` method; this limitation however\ndoesn\'t affect the ``format()`` function.\n\nThe meaning of the various alignment options is as follows:\n\n   +-----------+------------------------------------------------------------+\n   | Option    | Meaning                                                    |\n   +===========+============================================================+\n   | ``\'<\'``   | Forces the field to be left-aligned within the available   |\n   |           | space (this is the default for most objects).              |\n   +-----------+------------------------------------------------------------+\n   | ``\'>\'``   | Forces the field to be right-aligned within the available  |\n   |           | space (this is the default for numbers).                   |\n   +-----------+------------------------------------------------------------+\n   | ``\'=\'``   | Forces the padding to be placed after the sign (if any)    |\n   |           | but before the digits.  This is used for printing fields   |\n   |           | in the form \'+000000120\'. This alignment option is only    |\n   |           | valid for numeric types.                                   |\n   +-----------+------------------------------------------------------------+\n   | ``\'^\'``   | Forces the field to be centered within the available       |\n   |           | space.                                                     |\n   +-----------+------------------------------------------------------------+\n\nNote that unless a minimum field width is defined, the field width\nwill always be the same size as the data to fill it, so that the\nalignment option has no meaning in this case.\n\nThe *sign* option is only valid for number types, and can be one of\nthe following:\n\n   +-----------+------------------------------------------------------------+\n   | Option    | Meaning                                                    |\n   +===========+============================================================+\n   | ``\'+\'``   | indicates that a sign should be used for both positive as  |\n   |           | well as negative numbers.                                  |\n   +-----------+------------------------------------------------------------+\n   | ``\'-\'``   | indicates that a sign should be used only for negative     |\n   |           | numbers (this is the default behavior).                    |\n   +-----------+------------------------------------------------------------+\n   | space     | indicates that a leading space should be used on positive  |\n   |           | numbers, and a minus sign on negative numbers.             |\n   +-----------+------------------------------------------------------------+\n\nThe ``\'#\'`` option is only valid for integers, and only for binary,\noctal, or hexadecimal output.  If present, it specifies that the\noutput will be prefixed by ``\'0b\'``, ``\'0o\'``, or ``\'0x\'``,\nrespectively.\n\nThe ``\',\'`` option signals the use of a comma for a thousands\nseparator. For a locale aware separator, use the ``\'n\'`` integer\npresentation type instead.\n\nChanged in version 2.7: Added the ``\',\'`` option (see also **PEP\n378**).\n\n*width* is a decimal integer defining the minimum field width.  If not\nspecified, then the field width will be determined by the content.\n\nPreceding the *width* field by a zero (``\'0\'``) character enables\nsign-aware zero-padding for numeric types.  This is equivalent to a\n*fill* character of ``\'0\'`` with an *alignment* type of ``\'=\'``.\n\nThe *precision* is a decimal number indicating how many digits should\nbe displayed after the decimal point for a floating point value\nformatted with ``\'f\'`` and ``\'F\'``, or before and after the decimal\npoint for a floating point value formatted with ``\'g\'`` or ``\'G\'``.\nFor non-number types the field indicates the maximum field size - in\nother words, how many characters will be used from the field content.\nThe *precision* is not allowed for integer values.\n\nFinally, the *type* determines how the data should be presented.\n\nThe available string presentation types are:\n\n   +-----------+------------------------------------------------------------+\n   | Type      | Meaning                                                    |\n   +===========+============================================================+\n   | ``\'s\'``   | String format.

For a given precision ``p >= 1``, this    |\n   |           | rounds the number to ``p`` significant digits and then     |\n   |           | formats the result in either fixed-point format or in      |\n   |           | scientific notation, depending on its magnitude.  The      |\n   |           | precise rules are as follows: suppose that the result      |\n   |           | formatted with presentation type ``\'e\'`` and precision     |\n   |           | ``p-1`` would have exponent ``exp``.  Then if ``-4 <= exp  |\n   |           | < p``, the number is formatted with presentation type      |\n   |           | ``\'f\'`` and precision ``p-1-exp``. Otherwise, the number   |\n   |           | is formatted with presentation type ``\'e\'`` and precision  |\n   |           | ``p-1``. In both cases insignificant trailing zeros are    |\n   |           | removed from the significand, and the decimal point is     |\n   |           | also removed if there are no remaining digits following    |\n   |           | it.

A precision of ``0`` is treated as equivalent  |\n   |           | to a precision of ``1``.  The default precision is ``6``.  |\n   +-----------+------------------------------------------------------------+\n   | ``\'G\'``   | General format.

- 'function': '\nFunction definitions\n********************\n\nA function definition defines a user-defined function object (see\nsection *The standard type hierarchy*):\n\n   decorated      ::= decorators (classdef | funcdef)\n   decorators     ::= decorator+\n   decorator      ::= "@" dotted_name ["(" [argument_list [","]] ")"] NEWLINE\n   funcdef        ::= "def" funcname "(" [parameter_list] ")" ":" suite\n   dotted_name    ::= identifier ("." identifier)*\n   parameter_list ::= (defparameter ",")*\n                      (  "*" identifier ["," "**" identifier]\n                      | "**" identifier\n                      | defparameter [","] )\n   defparameter   ::= parameter ["=" expression]\n   sublist        ::= parameter ("," parameter)* [","]\n   parameter      ::= identifier | "(" sublist ")"\n   funcname       ::= identifier\n\nA function definition is an executable statement.  Its execution binds\nthe function name in the current local namespace to a function object\n(a wrapper around the executable code for the function).  This\nfunction object contains a reference to the current global namespace\nas the global namespace to be used when the function is called.\n\nThe function definition does not execute the function body; this gets\nexecuted only when the function is called. [3]\n\nA function definition may be wrapped by one or more *decorator*\nexpressions. Decorator expressions are evaluated when the function is\ndefined, in the scope that contains the function definition.  The\nresult must be a callable, which is invoked with the function object\nas the only argument. The returned value is bound to the function name\ninstead of the function object.  Multiple decorators are applied in\nnested fashion. For example, the following code:\n\n   @f1(arg)\n   @f2\n   def func(): pass\n\nis equivalent to:\n\n   def func(): pass\n   func = f1(arg)(f2(func))\n\nWhen one or more top-level *parameters* have the form *parameter*\n``=`` *expression*, the function is said to have "default parameter\nvalues."  For a parameter with a default value, the corresponding\n*argument* may be omitted from a call, in which case the parameter\'s\ndefault value is substituted.  If a parameter has a default value, all\nfollowing parameters must also have a default value --- this is a\nsyntactic restriction that is not expressed by the grammar.\n\n**Default parameter values are evaluated when the function definition\nis executed.**  This means that the expression is evaluated once, when\nthe function is defined, and that the same "pre-computed" value is\nused for each call.  This is especially important to understand when a\ndefault parameter is a mutable object, such as a list or a dictionary:\nif the function modifies the object (e.g. by appending an item to a\nlist), the default value is in effect modified. This is generally not\nwhat was intended.  A way around this  is to use ``None`` as the\ndefault, and explicitly test for it in the body of the function, e.g.:\n\n   def whats_on_the_telly(penguin=None):\n       if penguin is None:\n           penguin = []\n       penguin.append("property of the zoo")\n       return penguin\n\nFunction call semantics are described in more detail in section\n*Calls*. A function call always assigns values to all parameters\nmentioned in the parameter list, either from position arguments, from\nkeyword arguments, or from default values.  If the form\n"``*identifier``" is present, it is initialized to a tuple receiving\nany excess positional parameters, defaulting to the empty tuple.  If\nthe form "``**identifier``" is present, it is initialized to a new\ndictionary receiving any excess keyword arguments, defaulting to a new\nempty dictionary.\n\nIt is also possible to create anonymous functions (functions not bound\nto a name), for immediate use in expressions.  This uses lambda\nexpressions, described in section *Lambdas*.  Note that the lambda\nexpression is merely a shorthand for a simplified function definition;\na function defined in a "``def``" statement can be passed around or\nassigned to another name just like a function defined by a lambda\nexpression.  The "``def``" form is actually more powerful since it\nallows the execution of multiple statements.\n\n**Programmer\'s note:** Functions are first-class objects.  A "``def``"\nform executed inside a function definition defines a local function\nthat can be returned or passed around.  Free variables used in the\nnested function can access the local variables of the function\ncontaining the def.  See section *Naming and binding* for details.\n',
- 'global': '\nThe ``global`` statement\n************************\n\n   global_stmt ::= "global" identifier ("," identifier)*\n\nThe ``global`` statement is a declaration which holds for the entire\ncurrent code block.  It means that the listed identifiers are to be\ninterpreted as globals.  It would be impossible to assign to a global\nvariable without ``global``, although free variables may refer to\nglobals without being declared global.\n\nNames listed in a ``global`` statement must not be used in the same\ncode block textually preceding that ``global`` statement.\n\nNames listed in a ``global`` statement must not be defined as formal\nparameters or in a ``for`` loop control target, ``class`` definition,\nfunction definition, or ``import`` statement.\n\n**CPython implementation detail:** The current implementation does not\nenforce the latter two restrictions, but programs should not abuse\nthis freedom, as future implementations may enforce them or silently\nchange the meaning of the program.\n\n**Programmer\'s note:** the ``global`` is a directive to the parser.\nIt applies only to code parsed at the same time as the ``global``\nstatement. In particular, a ``global`` statement contained in an\n``exec`` statement does not affect the code block *containing* the\n``exec`` statement, and code contained in an ``exec`` statement is\nunaffected by ``global`` statements in the code containing the\n``exec`` statement.  The same applies to the ``eval()``,\n``execfile()`` and ``compile()`` functions.\n',

- 'import': '\nThe ``import`` statement\n************************\n\n   import_stmt     ::= "import" module ["as" name] ( "," module ["as" name] )*\n                   | "from" relative_module "import" identifier ["as" name]\n                   ( "," identifier ["as" name] )*\n                   | "from" relative_module "import" "(" identifier ["as" name]\n                   ( "," identifier ["as" name] )* [","] ")"\n                   | "from" module "import" "*"\n   module          ::= (identifier ".")* identifier\n   relative_module ::= "."* module | "."+\n   name            ::= identifier\n\nImport statements are executed in two steps: (1) find a module, and\ninitialize it if necessary; (2) define a name or names in the local\nnamespace (of the scope where the ``import`` statement occurs). The\nstatement comes in two forms differing on whether it uses the ``from``\nkeyword. The first form (without ``from``) repeats these steps for\neach identifier in the list. The form with ``from`` performs step (1)\nonce, and then performs step (2) repeatedly.\n\nTo understand how step (1) occurs, one must first understand how\nPython handles hierarchical naming of modules. To help organize\nmodules and provide a hierarchy in naming, Python has a concept of\npackages. A package can contain other packages and modules while\nmodules cannot contain other modules or packages. From a file system\nperspective, packages are directories and modules are files. The\noriginal specification for packages is still available to read,\nalthough minor details have changed since the writing of that\ndocument.\n\nOnce the name of the module is known (unless otherwise specified, the\nterm "module" will refer to both packages and modules), searching for\nthe module or package can begin. The first place checked is\n``sys.modules``, the cache of all modules that have been imported\npreviously. If the module is found there then it is used in step (2)\nof import.\n\nIf the module is not found in the cache, then ``sys.meta_path`` is\nsearched (the specification for ``sys.meta_path`` can be found in\n**PEP 302**). The object is a list of *finder* objects which are\nqueried in order as to whether they know how to load the module by\ncalling their ``find_module()`` method with the name of the module. If\nthe module happens to be contained within a package (as denoted by the\nexistence of a dot in the name), then a second argument to\n``find_module()`` is given as the value of the ``__path__`` attribute\nfrom the parent package (everything up to the last dot in the name of\nthe module being imported). If a finder can find the module it returns\na *loader* (discussed later) or returns ``None``.\n\nIf none of the finders on ``sys.meta_path`` are able to find the\nmodule then some implicitly defined finders are queried.\nImplementations of Python vary in what implicit meta path finders are\ndefined. The one they all do define, though, is one that handles\n``sys.path_hooks``, ``sys.path_importer_cache``, and ``sys.path``.\n\nThe implicit finder searches for the requested module in the "paths"\nspecified in one of two places ("paths" do not have to be file system\npaths). If the module being imported is supposed to be contained\nwithin a package then the second argument passed to ``find_module()``,\n``__path__`` on the parent package, is used as the source of paths. If\nthe module is not contained in a package then ``sys.path`` is used as\nthe source of paths.\n\nOnce the source of paths is chosen it is iterated over to find a\nfinder that can handle that path. The dict at\n``sys.path_importer_cache`` caches finders for paths and is checked\nfor a finder. If the path does not have a finder cached then\n``sys.path_hooks`` is searched by calling each object in the list with\na single argument of the path, returning a finder or raises\n``ImportError``. If a finder is returned then it is cached in\n``sys.path_importer_cache`` and then used for that path entry. If no\nfinder can be found but the path exists then a value of ``None`` is\nstored in ``sys.path_importer_cache`` to signify that an implicit,\nfile-based finder that handles modules stored as individual files\nshould be used for that path. If the path does not exist then a finder\nwhich always returns ``None`` is placed in the cache for the path.\n\nIf no finder can find the module then ``ImportError`` is raised.\nOtherwise some finder returned a loader whose ``load_module()`` method\nis called with the name of the module to load (see **PEP 302** for the\noriginal definition of loaders). A loader has several responsibilities\nto perform on a module it loads. First, if the module already exists\nin ``sys.modules`` (a possibility if the loader is called outside of\nthe import machinery) then it is to use that module for initialization\nand not a new module. But if the module does not exist in\n``sys.modules`` then it is to be added to that dict before\ninitialization begins. If an error occurs during loading of the module\nand it was added to ``sys.modules`` it is to be removed from the dict.\nIf an error occurs but the module was already in ``sys.modules`` it is\nleft in the dict.\n\nThe loader must set several attributes on the module. ``__name__`` is\nto be set to the name of the module. ``__file__`` is to be the "path"\nto the file unless the module is built-in (and thus listed in\n``sys.builtin_module_names``) in which case the attribute is not set.\nIf what is being imported is a package then ``__path__`` is to be set\nto a list of paths to be searched when looking for modules and\npackages contained within the package being imported. ``__package__``\nis optional but should be set to the name of package that contains the\nmodule or package (the empty string is used for module not contained\nin a package). ``__loader__`` is also optional but should be set to\nthe loader object that is loading the module.\n\nIf an error occurs during loading then the loader raises\n``ImportError`` if some other exception is not already being\npropagated. Otherwise the loader returns the module that was loaded\nand initialized.\n\nWhen step (1) finishes without raising an exception, step (2) can\nbegin.\n\nThe first form of ``import`` statement binds the module name in the\nlocal namespace to the module object, and then goes on to import the\nnext identifier, if any.  If the module name is followed by ``as``,\nthe name following ``as`` is used as the local name for the module.\n\nThe ``from`` form does not bind the module name: it goes through the\nlist of identifiers, looks each one of them up in the module found in\nstep (1), and binds the name in the local namespace to the object thus\nfound.  As with the first form of ``import``, an alternate local name\ncan be supplied by specifying "``as`` localname".  If a name is not\nfound, ``ImportError`` is raised.  If the list of identifiers is\nreplaced by a star (``\'*\'``), all public names defined in the module\nare bound in the local namespace of the ``import`` statement..\n\nThe *public names* defined by a module are determined by checking the\nmodule\'s namespace for a variable named ``__all__``; if defined, it\nmust be a sequence of strings which are names defined or imported by\nthat module.  The names given in ``__all__`` are all considered public\nand are required to exist.  If ``__all__`` is not defined, the set of\npublic names includes all names found in the module\'s namespace which\ndo not begin with an underscore character (``\'_\'``). ``__all__``\nshould contain the entire public API. It is intended to avoid\naccidentally exporting items that are not part of the API (such as\nlibrary modules which were imported and used within the module).\n\nThe ``from`` form with ``*`` may only occur in a module scope.  If the\nwild card form of import --- ``import *`` --- is used in a function\nand the function contains or is a nested block with free variables,\nthe compiler will raise a ``SyntaxError``.\n\nWhen specifying what module to import you do not have to specify the\nabsolute name of the module. When a module or package is contained\nwithin another package it is possible to make a relative import within\nthe same top package without having to mention the package name. By\nusing leading dots in the specified module or package after ``from``\nyou can specify how high to traverse up the current package hierarchy\nwithout specifying exact names. One leading dot means the current\npackage where the module making the import exists. Two dots means up\none package level. Three dots is up two levels, etc. So if you execute\n``from . import mod`` from a module in the ``pkg`` package then you\nwill end up importing ``pkg.mod``. If you execute ``from ..subpkg2\nimport mod`` from within ``pkg.subpkg1`` you will import\n``pkg.subpkg2.mod``. The specification for relative imports is\ncontained within **PEP 328**.\n\n``importlib.import_module()`` is provided to support applications that\ndetermine which modules need to be loaded dynamically.\n\n\nFuture statements\n=================\n\nA *future statement* is a directive to the compiler that a particular\nmodule should be compiled using syntax or semantics that will be\navailable in a specified future release of Python.  The future\nstatement is intended to ease migration to future versions of Python\nthat introduce incompatible changes to the language.  It allows use of\nthe new features on a per-module basis before the release in which the\nfeature becomes standard.\n\n   future_statement ::= "from" "__future__" "import" feature ["as" name]\n                        ("," feature ["as" name])*\n                        | "from" "__future__" "import" "(" feature ["as" name]\n                        ("," feature ["as" name])* [","] ")"\n   feature          ::= identifier\n   name             ::= identifier\n\nA future statement must appear near the top of the module.  The only\nlines that can appear before a future statement are:\n\n* the module docstring (if any),\n\n* comments,\n\n* blank lines, and\n\n* other future statements.\n\nThe features recognized by Python 2.6 are ``unicode_literals``,\n``print_function``, ``absolute_import``, ``division``, ``generators``,\n``nested_scopes`` and ``with_statement``.  ``generators``,\n``with_statement``, ``nested_scopes`` are redundant in Python version\n2.6 and above because they are always enabled.\n\nA future statement is recognized and treated specially at compile\ntime: Changes to the semantics of core constructs are often\nimplemented by generating different code.  It may even be the case\nthat a new feature introduces new incompatible syntax (such as a new\nreserved word), in which case the compiler may need to parse the\nmodule differently.  Such decisions cannot be pushed off until\nruntime.\n\nFor any given release, the compiler knows which feature names have\nbeen defined, and raises a compile-time error if a future statement\ncontains a feature not known to it.\n\nThe direct runtime semantics are the same as for any import statement:\nthere is a standard module ``__future__``, described later, and it\nwill be imported in the usual way at the time the future statement is\nexecuted.\n\nThe interesting runtime semantics depend on the specific feature\nenabled by the future statement.\n\nNote that there is nothing special about the statement:\n\n   import __future__ [as name]\n\nThat is not a future statement; it\'s an ordinary import statement with\nno special semantics or syntax restrictions.\n\nCode compiled by an ``exec`` statement or calls to the built-in\nfunctions ``compile()`` and ``execfile()`` that occur in a module\n``M`` containing a future statement will, by default, use the new\nsyntax or semantics associated with the future statement.  This can,\nstarting with Python 2.2 be controlled by optional arguments to\n``compile()`` --- see the documentation of that function for details.\n\nA future statement typed at an interactive interpreter prompt will\ntake effect for the rest of the interpreter session.  If an\ninterpreter is started with the *-i* option, is passed a script name\nto execute, and the script includes a future statement, it will be in\neffect in the interactive session started after the script is\nexecuted.\n\nSee also:\n\n   **PEP 236** - Back to the __future__\n      The original proposal for the __future__ mechanism.\n',
- 'in': '\nComparisons\n***********\n\nUnlike C, all comparison operations in Python have the same priority,\nwhich is lower than that of any arithmetic, shifting or bitwise\noperation.  Also unlike C, expressions like ``a < b < c`` have the\ninterpretation that is conventional in mathematics:\n\n   comparison    ::= or_expr ( comp_operator or_expr )*\n   comp_operator ::= "<" | ">" | "==" | ">=" | "<=" | "<>" | "!="\n                     | "is" ["not"] | ["not"] "in"\n\nComparisons yield boolean values: ``True`` or ``False``.\n\nComparisons can be chained arbitrarily, e.g., ``x < y <= z`` is\nequivalent to ``x < y and y <= z``, except that ``y`` is evaluated\nonly once (but in both cases ``z`` is not evaluated at all when ``x <\ny`` is found to be false).\n\nFormally, if *a*, *b*, *c*, ..., *y*, *z* are expressions and *op1*,\n*op2*, ..., *opN* are comparison operators, then ``a op1 b op2 c ... y\nopN z`` is equivalent to ``a op1 b and b op2 c and ... y opN z``,\nexcept that each expression is evaluated at most once.\n\nNote that ``a op1 b op2 c`` doesn\'t imply any kind of comparison\nbetween *a* and *c*, so that, e.g., ``x < y > z`` is perfectly legal\n(though perhaps not pretty).\n\nThe forms ``<>`` and ``!=`` are equivalent; for consistency with C,\n``!=`` is preferred; where ``!=`` is mentioned below ``<>`` is also\naccepted.  The ``<>`` spelling is considered obsolescent.\n\nThe operators ``<``, ``>``, ``==``, ``>=``, ``<=``, and ``!=`` compare\nthe values of two objects.  The objects need not have the same type.\nIf both are numbers, they are converted to a common type.  Otherwise,\nobjects of different types *always* compare unequal, and are ordered\nconsistently but arbitrarily. You can control comparison behavior of\nobjects of non-built-in types by defining a ``__cmp__`` method or rich\ncomparison methods like ``__gt__``, described in section *Special\nmethod names*.\n\n(This unusual definition of comparison was used to simplify the\ndefinition of operations like sorting and the ``in`` and ``not in``\noperators. In the future, the comparison rules for objects of\ndifferent types are likely to change.)\n\nComparison of objects of the same type depends on the type:\n\n* Numbers are compared arithmetically.\n\n* Strings are compared lexicographically using the numeric equivalents\n  (the result of the built-in function ``ord()``) of their characters.\n  Unicode and 8-bit strings are fully interoperable in this behavior.\n  [4]\n\n* Tuples and lists are compared lexicographically using comparison of\n  corresponding elements.  This means that to compare equal, each\n  element must compare equal and the two sequences must be of the same\n  type and have the same length.\n\n  If not equal, the sequences are ordered the same as their first\n  differing elements.  For example, ``cmp([1,2,x], [1,2,y])`` returns\n  the same as ``cmp(x,y)``.  If the corresponding element does not\n  exist, the shorter sequence is ordered first (for example, ``[1,2] <\n  [1,2,3]``).\n\n* Mappings (dictionaries) compare equal if and only if their sorted\n  (key, value) lists compare equal. [5] Outcomes other than equality\n  are resolved consistently, but are not otherwise defined. [6]\n\n* Most other objects of built-in types compare unequal unless they are\n  the same object; the choice whether one object is considered smaller\n  or larger than another one is made arbitrarily but consistently\n  within one execution of a program.\n\nThe operators ``in`` and ``not in`` test for collection membership.\n``x in s`` evaluates to true if *x* is a member of the collection *s*,\nand false otherwise.  ``x not in s`` returns the negation of ``x in\ns``. The collection membership test has traditionally been bound to\nsequences; an object is a member of a collection if the collection is\na sequence and contains an element equal to that object.  However, it\nmake sense for many other object types to support membership tests\nwithout being a sequence.  In particular, dictionaries (for keys) and\nsets support membership testing.\n\nFor the list and tuple types, ``x in y`` is true if and only if there\nexists an index *i* such that ``x == y[i]`` is true.\n\nFor the Unicode and string types, ``x in y`` is true if and only if\n*x* is a substring of *y*.  An equivalent test is ``y.find(x) != -1``.\nNote, *x* and *y* need not be the same type; consequently, ``u\'ab\' in\n\'abc\'`` will return ``True``. Empty strings are always considered to\nbe a substring of any other string, so ``"" in "abc"`` will return\n``True``.\n\nChanged in version 2.3: Previously, *x* was required to be a string of\nlength ``1``.\n\nFor user-defined classes which define the ``__contains__()`` method,\n``x in y`` is true if and only if ``y.__contains__(x)`` is true.\n\nFor user-defined classes which do not define ``__contains__()`` but do\ndefine ``__iter__()``, ``x in y`` is true if some value ``z`` with ``x\n== z`` is produced while iterating over ``y``.  If an exception is\nraised during the iteration, it is as if ``in`` raised that exception.\n\nLastly, the old-style iteration protocol is tried: if a class defines\n``__getitem__()``, ``x in y`` is true if and only if there is a non-\nnegative integer index *i* such that ``x == y[i]``, and all lower\ninteger indices do not raise ``IndexError`` exception. (If any other\nexception is raised, it is as if ``in`` raised that exception).\n\nThe operator ``not in`` is defined to have the inverse true value of\n``in``.\n\nThe operators ``is`` and ``is not`` test for object identity: ``x is\ny`` is true if and only if *x* and *y* are the same object.  ``x is\nnot y`` yields the inverse truth value.

- 'integers': '\nInteger and long integer literals\n*********************************\n\nInteger and long integer literals are described by the following\nlexical definitions:\n\n   longinteger    ::= integer ("l" | "L")\n   integer        ::= decimalinteger | octinteger | hexinteger | bininteger\n   decimalinteger ::= nonzerodigit digit* | "0"\n   octinteger     ::= "0" ("o" | "O") octdigit+ | "0" octdigit+\n   hexinteger     ::= "0" ("x" | "X") hexdigit+\n   bininteger     ::= "0" ("b" | "B") bindigit+\n   nonzerodigit   ::= "1"..."9"\n   octdigit       ::= "0"..."7"\n   bindigit       ::= "0" | "1"\n   hexdigit       ::= digit | "a"..."f" | "A"..."F"\n\nAlthough both lower case ``\'l\'`` and upper case ``\'L\'`` are allowed as\nsuffix for long integers, it is strongly recommended to always use\n``\'L\'``, since the letter ``\'l\'`` looks too much like the digit\n``\'1\'``.\n\nPlain integer literals that are above the largest representable plain\ninteger (e.g., 2147483647 when using 32-bit arithmetic) are accepted\nas if they were long integers instead.

- 'naming': "\nNaming and binding\n******************\n\n*Names* refer to objects.  Names are introduced by name binding\noperations. Each occurrence of a name in the program text refers to\nthe *binding* of that name established in the innermost function block\ncontaining the use.\n\nA *block* is a piece of Python program text that is executed as a\nunit. The following are blocks: a module, a function body, and a class\ndefinition. Each command typed interactively is a block.  A script\nfile (a file given as standard input to the interpreter or specified\non the interpreter command line the first argument) is a code block.\nA script command (a command specified on the interpreter command line\nwith the '**-c**' option) is a code block.  The file read by the\nbuilt-in function ``execfile()`` is a code block.  The string argument\npassed to the built-in function ``eval()`` and to the ``exec``\nstatement is a code block. The expression read and evaluated by the\nbuilt-in function ``input()`` is a code block.\n\nA code block is executed in an *execution frame*.  A frame contains\nsome administrative information (used for debugging) and determines\nwhere and how execution continues after the code block's execution has\ncompleted.\n\nA *scope* defines the visibility of a name within a block.  If a local\nvariable is defined in a block, its scope includes that block.  If the\ndefinition occurs in a function block, the scope extends to any blocks\ncontained within the defining one, unless a contained block introduces\na different binding for the name.  The scope of names defined in a\nclass block is limited to the class block; it does not extend to the\ncode blocks of methods -- this includes generator expressions since\nthey are implemented using a function scope.  This means that the\nfollowing will fail:\n\n   class A:\n       a = 42\n       b = list(a + i for i in range(10))\n\nWhen a name is used in a code block, it is resolved using the nearest\nenclosing scope.  The set of all such scopes visible to a code block\nis called the block's *environment*.\n\nIf a name is bound in a block, it is a local variable of that block.\nIf a name is bound at the module level, it is a global variable.  (The\nvariables of the module code block are local and global.)  If a\nvariable is used in a code block but not defined there, it is a *free\nvariable*.\n\nWhen a name is not found at all, a ``NameError`` exception is raised.\nIf the name refers to a local variable that has not been bound, a\n``UnboundLocalError`` exception is raised.  ``UnboundLocalError`` is a\nsubclass of ``NameError``.\n\nThe following constructs bind names: formal parameters to functions,\n``import`` statements, class and function definitions (these bind the\nclass or function name in the defining block), and targets that are\nidentifiers if occurring in an assignment, ``for`` loop header, in the\nsecond position of an ``except`` clause header or after ``as`` in a\n``with`` statement.  The ``import`` statement of the form ``from ...\nimport *`` binds all names defined in the imported module, except\nthose beginning with an underscore.  This form may only be used at the\nmodule level.\n\nA target occurring in a ``del`` statement is also considered bound for\nthis purpose (though the actual semantics are to unbind the name).  It\nis illegal to unbind a name that is referenced by an enclosing scope;\nthe compiler will report a ``SyntaxError``.\n\nEach assignment or import statement occurs within a block defined by a\nclass or function definition or at the module level (the top-level\ncode block).\n\nIf a name binding operation occurs anywhere within a code block, all\nuses of the name within the block are treated as references to the\ncurrent block.  This can lead to errors when a name is used within a\nblock before it is bound. This rule is subtle.  Python lacks\ndeclarations and allows name binding operations to occur anywhere\nwithin a code block.  The local variables of a code block can be\ndetermined by scanning the entire text of the block for name binding\noperations.\n\nIf the global statement occurs within a block, all uses of the name\nspecified in the statement refer to the binding of that name in the\ntop-level namespace. Names are resolved in the top-level namespace by\nsearching the global namespace, i.e. the namespace of the module\ncontaining the code block, and the builtins namespace, the namespace\nof the module ``__builtin__``.  The global namespace is searched\nfirst.  If the name is not found there, the builtins namespace is\nsearched.  The global statement must precede all uses of the name.\n\nThe builtins namespace associated with the execution of a code block\nis actually found by looking up the name ``__builtins__`` in its\nglobal namespace; this should be a dictionary or a module (in the\nlatter case the module's dictionary is used).  By default, when in the\n``__main__`` module, ``__builtins__`` is the built-in module\n``__builtin__`` (note: no 's'); when in any other module,\n``__builtins__`` is an alias for the dictionary of the ``__builtin__``\nmodule itself.  ``__builtins__`` can be set to a user-created\ndictionary to create a weak form of restricted execution.\n\n**CPython implementation detail:** Users should not touch\n``__builtins__``; it is strictly an implementation detail.  Users\nwanting to override values in the builtins namespace should ``import``\nthe ``__builtin__`` (no 's') module and modify its attributes\nappropriately.\n\nThe namespace for a module is automatically created the first time a\nmodule is imported.  The main module for a script is always called\n``__main__``.\n\nThe ``global`` statement has the same scope as a name binding\noperation in the same block.  If the nearest enclosing scope for a\nfree variable contains a global statement, the free variable is\ntreated as a global.\n\nA class definition is an executable statement that may use and define\nnames. These references follow the normal rules for name resolution.\nThe namespace of the class definition becomes the attribute dictionary\nof the class.  Names defined at the class scope are not visible in\nmethods.\n\n\nInteraction with dynamic features\n=================================\n\nThere are several cases where Python statements are illegal when used\nin conjunction with nested scopes that contain free variables.\n\nIf a variable is referenced in an enclosing scope, it is illegal to\ndelete the name.  An error will be reported at compile time.\n\nIf the wild card form of import --- ``import *`` --- is used in a\nfunction and the function contains or is a nested block with free\nvariables, the compiler will raise a ``SyntaxError``.\n\nIf ``exec`` is used in a function and the function contains or is a\nnested block with free variables, the compiler will raise a\n``SyntaxError`` unless the exec explicitly specifies the local\nnamespace for the ``exec``.  (In other words, ``exec obj`` would be\nillegal, but ``exec obj in ns`` would be legal.)\n\nThe ``eval()``, ``execfile()``, and ``input()`` functions and the\n``exec`` statement do not have access to the full environment for\nresolving names.  Names may be resolved in the local and global\nnamespaces of the caller.  Free variables are not resolved in the\nnearest enclosing namespace, but in the global namespace. [1] The\n``exec`` statement and the ``eval()`` and ``execfile()`` functions\nhave optional arguments to override the global and local namespace.\nIf only one namespace is specified, it is used for both.\n",
- 'numbers': "\nNumeric literals\n****************\n\nThere are four types of numeric literals: plain integers, long\nintegers, floating point numbers, and imaginary numbers.  There are no\ncomplex literals (complex numbers can be formed by adding a real\nnumber and an imaginary number).\n\nNote that numeric literals do not include a sign; a phrase like ``-1``\nis actually an expression composed of the unary operator '``-``' and\nthe literal ``1``.\n",
- 'numeric-types': '\nEmulating numeric types\n***********************\n\nThe following methods can be defined to emulate numeric objects.\nMethods corresponding to operations that are not supported by the\nparticular kind of number implemented (e.g., bitwise operations for\nnon-integral numbers) should be left undefined.\n\nobject.__add__(self, other)\nobject.__sub__(self, other)\nobject.__mul__(self, other)\nobject.__floordiv__(self, other)\nobject.__mod__(self, other)\nobject.__divmod__(self, other)\nobject.__pow__(self, other[, modulo])\nobject.__lshift__(self, other)\nobject.__rshift__(self, other)\nobject.__and__(self, other)\nobject.__xor__(self, other)\nobject.__or__(self, other)\n\n   These methods are called to implement the binary arithmetic\n   operations (``+``, ``-``, ``*``, ``//``, ``%``, ``divmod()``,\n   ``pow()``, ``**``, ``<<``, ``>>``, ``&``, ``^``, ``|``).  For\n   instance, to evaluate the expression ``x + y``, where *x* is an\n   instance of a class that has an ``__add__()`` method,\n   ``x.__add__(y)`` is called.  The ``__divmod__()`` method should be\n   the equivalent to using ``__floordiv__()`` and ``__mod__()``; it\n   should not be related to ``__truediv__()`` (described below).  Note\n   that ``__pow__()`` should be defined to accept an optional third\n   argument if the ternary version of the built-in ``pow()`` function\n   is to be supported.\n\n   If one of those methods does not support the operation with the\n   supplied arguments, it should return ``NotImplemented``.\n\nobject.__div__(self, other)\nobject.__truediv__(self, other)\n\n   The division operator (``/``) is implemented by these methods.  The\n   ``__truediv__()`` method is used when ``__future__.division`` is in\n   effect, otherwise ``__div__()`` is used.  If only one of these two\n   methods is defined, the object will not support division in the\n   alternate context; ``TypeError`` will be raised instead.\n\nobject.__radd__(self, other)\nobject.__rsub__(self, other)\nobject.__rmul__(self, other)\nobject.__rdiv__(self, other)\nobject.__rtruediv__(self, other)\nobject.__rfloordiv__(self, other)\nobject.__rmod__(self, other)\nobject.__rdivmod__(self, other)\nobject.__rpow__(self, other)\nobject.__rlshift__(self, other)\nobject.__rrshift__(self, other)\nobject.__rand__(self, other)\nobject.__rxor__(self, other)\nobject.__ror__(self, other)\n\n   These methods are called to implement the binary arithmetic\n   operations (``+``, ``-``, ``*``, ``/``, ``%``, ``divmod()``,\n   ``pow()``, ``**``, ``<<``, ``>>``, ``&``, ``^``, ``|``) with\n   reflected (swapped) operands.  These functions are only called if\n   the left operand does not support the corresponding operation and\n   the operands are of different types. [2] For instance, to evaluate\n   the expression ``x - y``, where *y* is an instance of a class that\n   has an ``__rsub__()`` method, ``y.__rsub__(x)`` is called if\n   ``x.__sub__(y)`` returns *NotImplemented*.\n\n   Note that ternary ``pow()`` will not try calling ``__rpow__()``\n   (the coercion rules would become too complicated).\n\n   Note: If the right operand\'s type is a subclass of the left operand\'s\n     type and that subclass provides the reflected method for the\n     operation, this method will be called before the left operand\'s\n     non-reflected method.  This behavior allows subclasses to\n     override their ancestors\' operations.\n\nobject.__iadd__(self, other)\nobject.__isub__(self, other)\nobject.__imul__(self, other)\nobject.__idiv__(self, other)\nobject.__itruediv__(self, other)\nobject.__ifloordiv__(self, other)\nobject.__imod__(self, other)\nobject.__ipow__(self, other[, modulo])\nobject.__ilshift__(self, other)\nobject.__irshift__(self, other)\nobject.__iand__(self, other)\nobject.__ixor__(self, other)\nobject.__ior__(self, other)\n\n   These methods are called to implement the augmented arithmetic\n   assignments (``+=``, ``-=``, ``*=``, ``/=``, ``//=``, ``%=``,\n   ``**=``, ``<<=``, ``>>=``, ``&=``, ``^=``, ``|=``).  These methods\n   should attempt to do the operation in-place (modifying *self*) and\n   return the result (which could be, but does not have to be,\n   *self*).  If a specific method is not defined, the augmented\n   assignment falls back to the normal methods.  For instance, to\n   execute the statement ``x += y``, where *x* is an instance of a\n   class that has an ``__iadd__()`` method, ``x.__iadd__(y)`` is\n   called.  If *x* is an instance of a class that does not define a\n   ``__iadd__()`` method, ``x.__add__(y)`` and ``y.__radd__(x)`` are\n   considered, as with the evaluation of ``x + y``.\n\nobject.__neg__(self)\nobject.__pos__(self)\nobject.__abs__(self)\nobject.__invert__(self)\n\n   Called to implement the unary arithmetic operations (``-``, ``+``,\n   ``abs()`` and ``~``).\n\nobject.__complex__(self)\nobject.__int__(self)\nobject.__long__(self)\nobject.__float__(self)\n\n   Called to implement the built-in functions ``complex()``,\n   ``int()``, ``long()``, and ``float()``.

Should either\n   return a 2-tuple containing *self* and *other* converted to a\n   common numeric type, or ``None`` if conversion is impossible.  When\n   the common type would be the type of ``other``, it is sufficient to\n   return ``None``, since the interpreter will also ask the other\n   object to attempt a coercion (but sometimes, if the implementation\n   of the other type cannot be changed, it is useful to do the\n   conversion to the other type here).  A return value of\n   ``NotImplemented`` is equivalent to returning ``None``.\n',
- 'objects': '\nObjects, values and types\n*************************\n\n*Objects* are Python\'s abstraction for data.  All data in a Python\nprogram is represented by objects or by relations between objects. (In\na sense, and in conformance to Von Neumann\'s model of a "stored\nprogram computer," code is also represented by objects.)\n\nEvery object has an identity, a type and a value.  An object\'s\n*identity* never changes once it has been created; you may think of it\nas the object\'s address in memory.  The \'``is``\' operator compares the\nidentity of two objects; the ``id()`` function returns an integer\nrepresenting its identity (currently implemented as its address). An\nobject\'s *type* is also unchangeable. [1] An object\'s type determines\nthe operations that the object supports (e.g., "does it have a\nlength?") and also defines the possible values for objects of that\ntype.  The ``type()`` function returns an object\'s type (which is an\nobject itself).  The *value* of some objects can change.  Objects\nwhose value can change are said to be *mutable*; objects whose value\nis unchangeable once they are created are called *immutable*. (The\nvalue of an immutable container object that contains a reference to a\nmutable object can change when the latter\'s value is changed; however\nthe container is still considered immutable, because the collection of\nobjects it contains cannot be changed.  So, immutability is not\nstrictly the same as having an unchangeable value, it is more subtle.)\nAn object\'s mutability is determined by its type; for instance,\nnumbers, strings and tuples are immutable, while dictionaries and\nlists are mutable.\n\nObjects are never explicitly destroyed; however, when they become\nunreachable they may be garbage-collected.  An implementation is\nallowed to postpone garbage collection or omit it altogether --- it is\na matter of implementation quality how garbage collection is\nimplemented, as long as no objects are collected that are still\nreachable.\n\n**CPython implementation detail:** CPython currently uses a reference-\ncounting scheme with (optional) delayed detection of cyclically linked\ngarbage, which collects most objects as soon as they become\nunreachable, but is not guaranteed to collect garbage containing\ncircular references.  See the documentation of the ``gc`` module for\ninformation on controlling the collection of cyclic garbage. Other\nimplementations act differently and CPython may change. Do not depend\non immediate finalization of objects when they become unreachable (ex:\nalways close files).\n\nNote that the use of the implementation\'s tracing or debugging\nfacilities may keep objects alive that would normally be collectable.\nAlso note that catching an exception with a \'``try``...``except``\'\nstatement may keep objects alive.\n\nSome objects contain references to "external" resources such as open\nfiles or windows.  It is understood that these resources are freed\nwhen the object is garbage-collected, but since garbage collection is\nnot guaranteed to happen, such objects also provide an explicit way to\nrelease the external resource, usually a ``close()`` method. Programs\nare strongly recommended to explicitly close such objects.  The\n\'``try``...``finally``\' statement provides a convenient way to do\nthis.\n\nSome objects contain references to other objects; these are called\n*containers*. Examples of containers are tuples, lists and\ndictionaries.  The references are part of a container\'s value.  In\nmost cases, when we talk about the value of a container, we imply the\nvalues, not the identities of the contained objects; however, when we\ntalk about the mutability of a container, only the identities of the\nimmediately contained objects are implied.  So, if an immutable\ncontainer (like a tuple) contains a reference to a mutable object, its\nvalue changes if that mutable object is changed.\n\nTypes affect almost all aspects of object behavior.  Even the\nimportance of object identity is affected in some sense: for immutable\ntypes, operations that compute new values may actually return a\nreference to any existing object with the same type and value, while\nfor mutable objects this is not allowed.  E.g., after ``a = 1; b =\n1``, ``a`` and ``b`` may or may not refer to the same object with the\nvalue one, depending on the implementation, but after ``c = []; d =\n[]``, ``c`` and ``d`` are guaranteed to refer to two different,\nunique, newly created empty lists. (Note that ``c = d = []`` assigns\nthe same object to both ``c`` and ``d``.)\n',

However, this behavior is deprecated, and relying on it\n    will not work in Python 3.\n\n[2] While ``abs(x%y) < abs(y)`` is true mathematically, for floats it\n    may not be true numerically due to roundoff.  For example, and\n    assuming a platform on which a Python float is an IEEE 754 double-\n    precision number, in order that ``-1e-100 % 1e100`` have the same\n    sign as ``1e100``, the computed result is ``-1e-100 + 1e100``,\n    which is numerically exactly equal to ``1e100``.  The function\n    ``math.fmod()`` returns a result whose sign matches the sign of\n    the first argument instead, and so returns ``-1e-100`` in this\n    case. Which approach is more appropriate depends on the\n    application.\n\n[3] If x is very close to an exact integer multiple of y, it\'s\n    possible for ``floor(x/y)`` to be one larger than ``(x-x%y)/y``\n    due to rounding.  In such cases, Python returns the latter result,\n    in order to preserve that ``divmod(x,y)[0] * y + x % y`` be very\n    close to ``x``.\n\n[4] While comparisons between unicode strings make sense at the byte\n    level, they may be counter-intuitive to users. For example, the\n    strings ``u"\\u00C7"`` and ``u"\\u0043\\u0327"`` compare differently,\n    even though they both represent the same unicode character (LATIN\n    CAPITAL LETTER C WITH CEDILLA). To compare strings in a human\n    recognizable way, compare using ``unicodedata.normalize()``.\n\n[5] The implementation computes this efficiently, without constructing\n    lists or sorting.\n\n[6] Earlier versions of Python used lexicographic comparison of the\n    sorted (key, value) lists, but this was very expensive for the\n    common case of comparing for equality.  An even earlier version of\n    Python compared dictionaries by identity only, but this caused\n    surprises because people expected to be able to test a dictionary\n    for emptiness by comparing it to ``{}``.\n\n[7] Due to automatic garbage-collection, free lists, and the dynamic\n    nature of descriptors, you may notice seemingly unusual behaviour\n    in certain uses of the ``is`` operator, like those involving\n    comparisons between instance methods, or constants.  Check their\n    documentation for more info.\n\n[8] The ``%`` operator is also used for string formatting; the same\n    precedence applies.\n\n[9] The power operator ``**`` binds less tightly than an arithmetic or\n    bitwise unary operator on its right, that is, ``2**-1`` is\n    ``0.5``.\n',
- 'pass': '\nThe ``pass`` statement\n**********************\n\n   pass_stmt ::= "pass"\n\n``pass`` is a null operation --- when it is executed, nothing happens.\nIt is useful as a placeholder when a statement is required\nsyntactically, but no code needs to be executed, for example:\n\n   def f(arg): pass    # a function that does nothing (yet)\n\n   class C: pass       # a class with no methods (yet)\n',
- 'power': '\nThe power operator\n******************\n\nThe power operator binds more tightly than unary operators on its\nleft; it binds less tightly than unary operators on its right.  The\nsyntax is:\n\n   power ::= primary ["**" u_expr]\n\nThus, in an unparenthesized sequence of power and unary operators, the\noperators are evaluated from right to left (this does not constrain\nthe evaluation order for the operands): ``-1**2`` results in ``-1``.\n\nThe power operator has the same semantics as the built-in ``pow()``\nfunction, when called with two arguments: it yields its left argument\nraised to the power of its right argument.  The numeric arguments are\nfirst converted to a common type.  The result type is that of the\narguments after coercion.\n\nWith mixed operand types, the coercion rules for binary arithmetic\noperators apply. For int and long int operands, the result has the\nsame type as the operands (after coercion) unless the second argument\nis negative; in that case, all arguments are converted to float and a\nfloat result is delivered. For example, ``10**2`` returns ``100``, but\n``10**-2`` returns ``0.01``. (This last feature was added in Python\n2.2. In Python 2.1 and before, if both arguments were of integer types\nand the second argument was negative, an exception was raised).\n\nRaising ``0.0`` to a negative power results in a\n``ZeroDivisionError``. Raising a negative number to a fractional power\nresults in a ``ValueError``.\n',
- 'raise': '\nThe ``raise`` statement\n***********************\n\n   raise_stmt ::= "raise" [expression ["," expression ["," expression]]]\n\nIf no expressions are present, ``raise`` re-raises the last exception\nthat was active in the current scope.  If no exception is active in\nthe current scope, a ``TypeError`` exception is raised indicating that\nthis is an error (if running under IDLE, a ``Queue.Empty`` exception\nis raised instead).\n\nOtherwise, ``raise`` evaluates the expressions to get three objects,\nusing ``None`` as the value of omitted expressions.  The first two\nobjects are used to determine the *type* and *value* of the exception.\n\nIf the first object is an instance, the type of the exception is the\nclass of the instance, the instance itself is the value, and the\nsecond object must be ``None``.\n\nIf the first object is a class, it becomes the type of the exception.\nThe second object is used to determine the exception value: If it is\nan instance of the class, the instance becomes the exception value. If\nthe second object is a tuple, it is used as the argument list for the\nclass constructor; if it is ``None``, an empty argument list is used,\nand any other object is treated as a single argument to the\nconstructor.  The instance so created by calling the constructor is\nused as the exception value.\n\nIf a third object is present and not ``None``, it must be a traceback\nobject (see section *The standard type hierarchy*), and it is\nsubstituted instead of the current location as the place where the\nexception occurred.  If the third object is present and not a\ntraceback object or ``None``, a ``TypeError`` exception is raised.\nThe three-expression form of ``raise`` is useful to re-raise an\nexception transparently in an except clause, but ``raise`` with no\nexpressions should be preferred if the exception to be re-raised was\nthe most recently active exception in the current scope.\n\nAdditional information on exceptions can be found in section\n*Exceptions*, and information about handling exceptions is in section\n*The try statement*.\n',

In that context, a bare ``return``\nindicates that the generator is done and will cause ``StopIteration``\nto be raised.\n',
- 'sequence-types': "\nEmulating container types\n*************************\n\nThe following methods can be defined to implement container objects.\nContainers usually are sequences (such as lists or tuples) or mappings\n(like dictionaries), but can represent other containers as well.  The\nfirst set of methods is used either to emulate a sequence or to\nemulate a mapping; the difference is that for a sequence, the\nallowable keys should be the integers *k* for which ``0 <= k < N``\nwhere *N* is the length of the sequence, or slice objects, which\ndefine a range of items. (For backwards compatibility, the method\n``__getslice__()`` (see below) can also be defined to handle simple,\nbut not extended slices.) It is also recommended that mappings provide\nthe methods ``keys()``, ``values()``, ``items()``, ``has_key()``,\n``get()``, ``clear()``, ``setdefault()``, ``iterkeys()``,\n``itervalues()``, ``iteritems()``, ``pop()``, ``popitem()``,\n``copy()``, and ``update()`` behaving similar to those for Python's\nstandard dictionary objects.  The ``UserDict`` module provides a\n``DictMixin`` class to help create those methods from a base set of\n``__getitem__()``, ``__setitem__()``, ``__delitem__()``, and\n``keys()``. Mutable sequences should provide methods ``append()``,\n``count()``, ``index()``, ``extend()``, ``insert()``, ``pop()``,\n``remove()``, ``reverse()`` and ``sort()``, like Python standard list\nobjects.  Finally, sequence types should implement addition (meaning\nconcatenation) and multiplication (meaning repetition) by defining the\nmethods ``__add__()``, ``__radd__()``, ``__iadd__()``, ``__mul__()``,\n``__rmul__()`` and ``__imul__()`` described below; they should not\ndefine ``__coerce__()`` or other numerical operators.  It is\nrecommended that both mappings and sequences implement the\n``__contains__()`` method to allow efficient use of the ``in``\noperator; for mappings, ``in`` should be equivalent of ``has_key()``;\nfor sequences, it should search through the values.  It is further\nrecommended that both mappings and sequences implement the\n``__iter__()`` method to allow efficient iteration through the\ncontainer; for mappings, ``__iter__()`` should be the same as\n``iterkeys()``; for sequences, it should iterate through the values.\n\nobject.__len__(self)\n\n   Called to implement the built-in function ``len()``.  Should return\n   the length of the object, an integer ``>=`` 0.  Also, an object\n   that doesn't define a ``__nonzero__()`` method and whose\n   ``__len__()`` method returns zero is considered to be false in a\n   Boolean context.\n\nobject.__getitem__(self, key)\n\n   Called to implement evaluation of ``self[key]``. For sequence\n   types, the accepted keys should be integers and slice objects.\n   Note that the special interpretation of negative indexes (if the\n   class wishes to emulate a sequence type) is up to the\n   ``__getitem__()`` method. If *key* is of an inappropriate type,\n   ``TypeError`` may be raised; if of a value outside the set of\n   indexes for the sequence (after any special interpretation of\n   negative values), ``IndexError`` should be raised. For mapping\n   types, if *key* is missing (not in the container), ``KeyError``\n   should be raised.\n\n   Note: ``for`` loops expect that an ``IndexError`` will be raised for\n     illegal indexes to allow proper detection of the end of the\n     sequence.\n\nobject.__setitem__(self, key, value)\n\n   Called to implement assignment to ``self[key]``.  Same note as for\n   ``__getitem__()``.  This should only be implemented for mappings if\n   the objects support changes to the values for keys, or if new keys\n   can be added, or for sequences if elements can be replaced.  The\n   same exceptions should be raised for improper *key* values as for\n   the ``__getitem__()`` method.\n\nobject.__delitem__(self, key)\n\n   Called to implement deletion of ``self[key]``.  Same note as for\n   ``__getitem__()``.  This should only be implemented for mappings if\n   the objects support removal of keys, or for sequences if elements\n   can be removed from the sequence.  The same exceptions should be\n   raised for improper *key* values as for the ``__getitem__()``\n   method.\n\nobject.__iter__(self)\n\n   This method is called when an iterator is required for a container.\n   This method should return a new iterator object that can iterate\n   over all the objects in the container.  For mappings, it should\n   iterate over the keys of the container, and should also be made\n   available as the method ``iterkeys()``.\n\n   Iterator objects also need to implement this method; they are\n   required to return themselves.  For more information on iterator\n   objects, see *Iterator Types*.\n\nobject.__reversed__(self)\n\n   Called (if present) by the ``reversed()`` built-in to implement\n   reverse iteration.  It should return a new iterator object that\n   iterates over all the objects in the container in reverse order.\n\n   If the ``__reversed__()`` method is not provided, the\n   ``reversed()`` built-in will fall back to using the sequence\n   protocol (``__len__()`` and ``__getitem__()``).  Objects that\n   support the sequence protocol should only provide\n   ``__reversed__()`` if they can provide an implementation that is\n   more efficient than the one provided by ``reversed()``.\n\n   New in version 2.6.\n\nThe membership test operators (``in`` and ``not in``) are normally\nimplemented as an iteration through a sequence.  However, container\nobjects can supply the following special method with a more efficient\nimplementation, which also does not require the object be a sequence.\n\nobject.__contains__(self, item)\n\n   Called to implement membership test operators.  Should return true\n   if *item* is in *self*, false otherwise.  For mapping objects, this\n   should consider the keys of the mapping rather than the values or\n   the key-item pairs.\n\n   For objects that don't define ``__contains__()``, the membership\n   test first tries iteration via ``__iter__()``, then the old\n   sequence iteration protocol via ``__getitem__()``, see *this\n   section in the language reference*.\n",
- 'shifting': '\nShifting operations\n*******************\n\nThe shifting operations have lower priority than the arithmetic\noperations:\n\n   shift_expr ::= a_expr | shift_expr ( "<<" | ">>" ) a_expr\n\nThese operators accept plain or long integers as arguments.  The\narguments are converted to a common type.  They shift the first\nargument to the left or right by the number of bits given by the\nsecond argument.\n\nA right shift by *n* bits is defined as division by ``pow(2, n)``.  A\nleft shift by *n* bits is defined as multiplication with ``pow(2,\nn)``.  Negative shift counts raise a ``ValueError`` exception.\n\nNote: In the current implementation, the right-hand operand is required to\n  be at most ``sys.maxsize``.  If the right-hand operand is larger\n  than ``sys.maxsize`` an ``OverflowError`` exception is raised.\n',
- 'slicings': '\nSlicings\n********\n\nA slicing selects a range of items in a sequence object (e.g., a\nstring, tuple or list).  Slicings may be used as expressions or as\ntargets in assignment or ``del`` statements.  The syntax for a\nslicing:\n\n   slicing          ::= simple_slicing | extended_slicing\n   simple_slicing   ::= primary "[" short_slice "]"\n   extended_slicing ::= primary "[" slice_list "]"\n   slice_list       ::= slice_item ("," slice_item)* [","]\n   slice_item       ::= expression | proper_slice | ellipsis\n   proper_slice     ::= short_slice | long_slice\n   short_slice      ::= [lower_bound] ":" [upper_bound]\n   long_slice       ::= short_slice ":" [stride]\n   lower_bound      ::= expression\n   upper_bound      ::= expression\n   stride           ::= expression\n   ellipsis         ::= "..."\n\nThere is ambiguity in the formal syntax here: anything that looks like\nan expression list also looks like a slice list, so any subscription\ncan be interpreted as a slicing.  Rather than further complicating the\nsyntax, this is disambiguated by defining that in this case the\ninterpretation as a subscription takes priority over the\ninterpretation as a slicing (this is the case if the slice list\ncontains no proper slice nor ellipses).  Similarly, when the slice\nlist has exactly one short slice and no trailing comma, the\ninterpretation as a simple slicing takes priority over that as an\nextended slicing.\n\nThe semantics for a simple slicing are as follows.  The primary must\nevaluate to a sequence object.  The lower and upper bound expressions,\nif present, must evaluate to plain integers; defaults are zero and the\n``sys.maxint``, respectively.  If either bound is negative, the\nsequence\'s length is added to it.  The slicing now selects all items\nwith index *k* such that ``i <= k < j`` where *i* and *j* are the\nspecified lower and upper bounds.  This may be an empty sequence.  It\nis not an error if *i* or *j* lie outside the range of valid indexes\n(such items don\'t exist so they aren\'t selected).\n\nThe semantics for an extended slicing are as follows.  The primary\nmust evaluate to a mapping object, and it is indexed with a key that\nis constructed from the slice list, as follows.  If the slice list\ncontains at least one comma, the key is a tuple containing the\nconversion of the slice items; otherwise, the conversion of the lone\nslice item is the key.  The conversion of a slice item that is an\nexpression is that expression.  The conversion of an ellipsis slice\nitem is the built-in ``Ellipsis`` object.  The conversion of a proper\nslice is a slice object (see section *The standard type hierarchy*)\nwhose ``start``, ``stop`` and ``step`` attributes are the values of\nthe expressions given as lower bound, upper bound and stride,\nrespectively, substituting ``None`` for missing expressions.\n',
- 'specialattrs': '\nSpecial Attributes\n******************\n\nThe implementation adds a few special read-only attributes to several\nobject types, where they are relevant.  Some of these are not reported\nby the ``dir()`` built-in function.\n\nobject.__dict__\n\n   A dictionary or other mapping object used to store an object\'s\n   (writable) attributes.\n\nobject.__methods__\n\n   Deprecated since version 2.2: Use the built-in function ``dir()``\n   to get a list of an object\'s attributes. This attribute is no\n   longer available.\n\nobject.__members__\n\n   Deprecated since version 2.2: Use the built-in function ``dir()``\n   to get a list of an object\'s attributes. This attribute is no\n   longer available.\n\ninstance.__class__\n\n   The class to which a class instance belongs.\n\nclass.__bases__\n\n   The tuple of base classes of a class object.\n\nclass.__name__\n\n   The name of the class or type.\n\nThe following attributes are only supported by *new-style class*es.\n\nclass.__mro__\n\n   This attribute is a tuple of classes that are considered when\n   looking for base classes during method resolution.\n\nclass.mro()\n\n   This method can be overridden by a metaclass to customize the\n   method resolution order for its instances.  It is called at class\n   instantiation, and its result is stored in ``__mro__``.\n\nclass.__subclasses__()\n\n   Each new-style class keeps a list of weak references to its\n   immediate subclasses.  This method returns a list of all those\n   references still alive. Example:\n\n      >>> int.__subclasses__()\n      [<type \'bool\'>]\n\n-[ Footnotes ]-\n\n[1] Additional information on these special methods may be found in\n    the Python Reference Manual (*Basic customization*).\n\n[2] As a consequence, the list ``[1, 2]`` is considered equal to\n    ``[1.0, 2.0]``, and similarly for tuples.\n\n[3] They must have since the parser can\'t tell the type of the\n    operands.\n\n[4] Cased characters are those with general category property being\n    one of "Lu" (Letter, uppercase), "Ll" (Letter, lowercase), or "Lt"\n    (Letter, titlecase).\n\n[5] To format only a tuple you should therefore provide a singleton\n    tuple whose only element is the tuple to be formatted.\n\n[6] The advantage of leaving the newline on is that returning an empty\n    string is then an unambiguous EOF indication.  It is also possible\n    (in cases where it might matter, for example, if you want to make\n    an exact copy of a file while scanning its lines) to tell whether\n    the last line of a file ended in a newline or not (yes this\n    happens!).\n',
- 'specialnames': '\nSpecial method names\n********************\n\nA class can implement certain operations that are invoked by special\nsyntax (such as arithmetic operations or subscripting and slicing) by\ndefining methods with special names. This is Python\'s approach to\n*operator overloading*, allowing classes to define their own behavior\nwith respect to language operators.  For instance, if a class defines\na method named ``__getitem__()``, and ``x`` is an instance of this\nclass, then ``x[i]`` is roughly equivalent to ``x.__getitem__(i)`` for\nold-style classes and ``type(x).__getitem__(x, i)`` for new-style\nclasses.  Except where mentioned, attempts to execute an operation\nraise an exception when no appropriate method is defined (typically\n``AttributeError`` or ``TypeError``).\n\nWhen implementing a class that emulates any built-in type, it is\nimportant that the emulation only be implemented to the degree that it\nmakes sense for the object being modelled.  For example, some\nsequences may work well with retrieval of individual elements, but\nextracting a slice may not make sense.  (One example of this is the\n``NodeList`` interface in the W3C\'s Document Object Model.)\n\n\nBasic customization\n===================\n\nobject.__new__(cls[, ...])\n\n   Called to create a new instance of class *cls*.  ``__new__()`` is a\n   static method (special-cased so you need not declare it as such)\n   that takes the class of which an instance was requested as its\n   first argument.  The remaining arguments are those passed to the\n   object constructor expression (the call to the class).  The return\n   value of ``__new__()`` should be the new object instance (usually\n   an instance of *cls*).\n\n   Typical implementations create a new instance of the class by\n   invoking the superclass\'s ``__new__()`` method using\n   ``super(currentclass, cls).__new__(cls[, ...])`` with appropriate\n   arguments and then modifying the newly-created instance as\n   necessary before returning it.\n\n   If ``__new__()`` returns an instance of *cls*, then the new\n   instance\'s ``__init__()`` method will be invoked like\n   ``__init__(self[, ...])``, where *self* is the new instance and the\n   remaining arguments are the same as were passed to ``__new__()``.\n\n   If ``__new__()`` does not return an instance of *cls*, then the new\n   instance\'s ``__init__()`` method will not be invoked.\n\n   ``__new__()`` is intended mainly to allow subclasses of immutable\n   types (like int, str, or tuple) to customize instance creation.  It\n   is also commonly overridden in custom metaclasses in order to\n   customize class creation.\n\nobject.__init__(self[, ...])\n\n   Called when the instance is created.  The arguments are those\n   passed to the class constructor expression.  If a base class has an\n   ``__init__()`` method, the derived class\'s ``__init__()`` method,\n   if any, must explicitly call it to ensure proper initialization of\n   the base class part of the instance; for example:\n   ``BaseClass.__init__(self, [args...])``.  As a special constraint\n   on constructors, no value may be returned; doing so will cause a\n   ``TypeError`` to be raised at runtime.\n\nobject.__del__(self)\n\n   Called when the instance is about to be destroyed.  This is also\n   called a destructor.  If a base class has a ``__del__()`` method,\n   the derived class\'s ``__del__()`` method, if any, must explicitly\n   call it to ensure proper deletion of the base class part of the\n   instance.  Note that it is possible (though not recommended!) for\n   the ``__del__()`` method to postpone destruction of the instance by\n   creating a new reference to it.  It may then be called at a later\n   time when this new reference is deleted.  It is not guaranteed that\n   ``__del__()`` methods are called for objects that still exist when\n   the interpreter exits.\n\n   Note: ``del x`` doesn\'t directly call ``x.__del__()`` --- the former\n     decrements the reference count for ``x`` by one, and the latter\n     is only called when ``x``\'s reference count reaches zero.  Some\n     common situations that may prevent the reference count of an\n     object from going to zero include: circular references between\n     objects (e.g., a doubly-linked list or a tree data structure with\n     parent and child pointers); a reference to the object on the\n     stack frame of a function that caught an exception (the traceback\n     stored in ``sys.exc_traceback`` keeps the stack frame alive); or\n     a reference to the object on the stack frame that raised an\n     unhandled exception in interactive mode (the traceback stored in\n     ``sys.last_traceback`` keeps the stack frame alive).  The first\n     situation can only be remedied by explicitly breaking the cycles;\n     the latter two situations can be resolved by storing ``None`` in\n     ``sys.exc_traceback`` or ``sys.last_traceback``.  Circular\n     references which are garbage are detected when the option cycle\n     detector is enabled (it\'s on by default), but can only be cleaned\n     up if there are no Python-level ``__del__()`` methods involved.\n     Refer to the documentation for the ``gc`` module for more\n     information about how ``__del__()`` methods are handled by the\n     cycle detector, particularly the description of the ``garbage``\n     value.\n\n   Warning: Due to the precarious circumstances under which ``__del__()``\n     methods are invoked, exceptions that occur during their execution\n     are ignored, and a warning is printed to ``sys.stderr`` instead.\n     Also, when ``__del__()`` is invoked in response to a module being\n     deleted (e.g., when execution of the program is done), other\n     globals referenced by the ``__del__()`` method may already have\n     been deleted or in the process of being torn down (e.g. the\n     import machinery shutting down).  For this reason, ``__del__()``\n     methods should do the absolute minimum needed to maintain\n     external invariants.  Starting with version 1.5, Python\n     guarantees that globals whose name begins with a single\n     underscore are deleted from their module before other globals are\n     deleted; if no other references to such globals exist, this may\n     help in assuring that imported modules are still available at the\n     time when the ``__del__()`` method is called.\n\n   See also the *-R* command-line option.\n\nobject.__repr__(self)\n\n   Called by the ``repr()`` built-in function and by string\n   conversions (reverse quotes) to compute the "official" string\n   representation of an object.  If at all possible, this should look\n   like a valid Python expression that could be used to recreate an\n   object with the same value (given an appropriate environment).  If\n   this is not possible, a string of the form ``<...some useful\n   description...>`` should be returned.  The return value must be a\n   string object. If a class defines ``__repr__()`` but not\n   ``__str__()``, then ``__repr__()`` is also used when an "informal"\n   string representation of instances of that class is required.\n\n   This is typically used for debugging, so it is important that the\n   representation is information-rich and unambiguous.\n\nobject.__str__(self)\n\n   Called by the ``str()`` built-in function and by the ``print``\n   statement to compute the "informal" string representation of an\n   object.  This differs from ``__repr__()`` in that it does not have\n   to be a valid Python expression: a more convenient or concise\n   representation may be used instead. The return value must be a\n   string object.\n\nobject.__lt__(self, other)\nobject.__le__(self, other)\nobject.__eq__(self, other)\nobject.__ne__(self, other)\nobject.__gt__(self, other)\nobject.__ge__(self, other)\n\n   New in version 2.1.\n\n   These are the so-called "rich comparison" methods, and are called\n   for comparison operators in preference to ``__cmp__()`` below. The\n   correspondence between operator symbols and method names is as\n   follows: ``x<y`` calls ``x.__lt__(y)``, ``x<=y`` calls\n   ``x.__le__(y)``, ``x==y`` calls ``x.__eq__(y)``, ``x!=y`` and\n   ``x<>y`` call ``x.__ne__(y)``, ``x>y`` calls ``x.__gt__(y)``, and\n   ``x>=y`` calls ``x.__ge__(y)``.\n\n   A rich comparison method may return the singleton\n   ``NotImplemented`` if it does not implement the operation for a\n   given pair of arguments. By convention, ``False`` and ``True`` are\n   returned for a successful comparison. However, these methods can\n   return any value, so if the comparison operator is used in a\n   Boolean context (e.g., in the condition of an ``if`` statement),\n   Python will call ``bool()`` on the value to determine if the result\n   is true or false.\n\n   There are no implied relationships among the comparison operators.\n   The truth of ``x==y`` does not imply that ``x!=y`` is false.\n   Accordingly, when defining ``__eq__()``, one should also define\n   ``__ne__()`` so that the operators will behave as expected.  See\n   the paragraph on ``__hash__()`` for some important notes on\n   creating *hashable* objects which support custom comparison\n   operations and are usable as dictionary keys.\n\n   There are no swapped-argument versions of these methods (to be used\n   when the left argument does not support the operation but the right\n   argument does); rather, ``__lt__()`` and ``__gt__()`` are each\n   other\'s reflection, ``__le__()`` and ``__ge__()`` are each other\'s\n   reflection, and ``__eq__()`` and ``__ne__()`` are their own\n   reflection.\n\n   Arguments to rich comparison methods are never coerced.\n\n   To automatically generate ordering operations from a single root\n   operation, see ``functools.total_ordering()``.\n\nobject.__cmp__(self, other)\n\n   Called by comparison operations if rich comparison (see above) is\n   not defined.  Should return a negative integer if ``self < other``,\n   zero if ``self == other``, a positive integer if ``self > other``.\n   If no ``__cmp__()``, ``__eq__()`` or ``__ne__()`` operation is\n   defined, class instances are compared by object identity\n   ("address").  See also the description of ``__hash__()`` for some\n   important notes on creating *hashable* objects which support custom\n   comparison operations and are usable as dictionary keys. (Note: the\n   restriction that exceptions are not propagated by ``__cmp__()`` has\n   been removed since Python 1.5.)\n\nobject.__rcmp__(self, other)\n\n   Changed in version 2.1: No longer supported.\n\nobject.__hash__(self)\n\n   Called by built-in function ``hash()`` and for operations on\n   members of hashed collections including ``set``, ``frozenset``, and\n   ``dict``.  ``__hash__()`` should return an integer.  The only\n   required property is that objects which compare equal have the same\n   hash value; it is advised to somehow mix together (e.g. using\n   exclusive or) the hash values for the components of the object that\n   also play a part in comparison of objects.\n\n   If a class does not define a ``__cmp__()`` or ``__eq__()`` method\n   it should not define a ``__hash__()`` operation either; if it\n   defines ``__cmp__()`` or ``__eq__()`` but not ``__hash__()``, its\n   instances will not be usable in hashed collections.  If a class\n   defines mutable objects and implements a ``__cmp__()`` or\n   ``__eq__()`` method, it should not implement ``__hash__()``, since\n   hashable collection implementations require that a object\'s hash\n   value is immutable (if the object\'s hash value changes, it will be\n   in the wrong hash bucket).\n\n   User-defined classes have ``__cmp__()`` and ``__hash__()`` methods\n   by default; with them, all objects compare unequal (except with\n   themselves) and ``x.__hash__()`` returns ``id(x)``.\n\n   Classes which inherit a ``__hash__()`` method from a parent class\n   but change the meaning of ``__cmp__()`` or ``__eq__()`` such that\n   the hash value returned is no longer appropriate (e.g. by switching\n   to a value-based concept of equality instead of the default\n   identity based equality) can explicitly flag themselves as being\n   unhashable by setting ``__hash__ = None`` in the class definition.\n   Doing so means that not only will instances of the class raise an\n   appropriate ``TypeError`` when a program attempts to retrieve their\n   hash value, but they will also be correctly identified as\n   unhashable when checking ``isinstance(obj, collections.Hashable)``\n   (unlike classes which define their own ``__hash__()`` to explicitly\n   raise ``TypeError``).\n\n   Changed in version 2.5: ``__hash__()`` may now also return a long\n   integer object; the 32-bit integer is then derived from the hash of\n   that object.\n\n   Changed in version 2.6: ``__hash__`` may now be set to ``None`` to\n   explicitly flag instances of a class as unhashable.\n\nobject.__nonzero__(self)\n\n   Called to implement truth value testing and the built-in operation\n   ``bool()``; should return ``False`` or ``True``, or their integer\n   equivalents ``0`` or ``1``.  When this method is not defined,\n   ``__len__()`` is called, if it is defined, and the object is\n   considered true if its result is nonzero. If a class defines\n   neither ``__len__()`` nor ``__nonzero__()``, all its instances are\n   considered true.\n\nobject.__unicode__(self)\n\n   Called to implement ``unicode()`` built-in; should return a Unicode\n   object. When this method is not defined, string conversion is\n   attempted, and the result of string conversion is converted to\n   Unicode using the system default encoding.\n\n\nCustomizing attribute access\n============================\n\nThe following methods can be defined to customize the meaning of\nattribute access (use of, assignment to, or deletion of ``x.name``)\nfor class instances.\n\nobject.__getattr__(self, name)\n\n   Called when an attribute lookup has not found the attribute in the\n   usual places (i.e. it is not an instance attribute nor is it found\n   in the class tree for ``self``).  ``name`` is the attribute name.\n   This method should return the (computed) attribute value or raise\n   an ``AttributeError`` exception.\n\n   Note that if the attribute is found through the normal mechanism,\n   ``__getattr__()`` is not called.  (This is an intentional asymmetry\n   between ``__getattr__()`` and ``__setattr__()``.) This is done both\n   for efficiency reasons and because otherwise ``__getattr__()``\n   would have no way to access other attributes of the instance.  Note\n   that at least for instance variables, you can fake total control by\n   not inserting any values in the instance attribute dictionary (but\n   instead inserting them in another object).  See the\n   ``__getattribute__()`` method below for a way to actually get total\n   control in new-style classes.\n\nobject.__setattr__(self, name, value)\n\n   Called when an attribute assignment is attempted.  This is called\n   instead of the normal mechanism (i.e. store the value in the\n   instance dictionary).  *name* is the attribute name, *value* is the\n   value to be assigned to it.\n\n   If ``__setattr__()`` wants to assign to an instance attribute, it\n   should not simply execute ``self.name = value`` --- this would\n   cause a recursive call to itself.  Instead, it should insert the\n   value in the dictionary of instance attributes, e.g.,\n   ``self.__dict__[name] = value``.  For new-style classes, rather\n   than accessing the instance dictionary, it should call the base\n   class method with the same name, for example,\n   ``object.__setattr__(self, name, value)``.\n\nobject.__delattr__(self, name)\n\n   Like ``__setattr__()`` but for attribute deletion instead of\n   assignment.  This should only be implemented if ``del obj.name`` is\n   meaningful for the object.\n\n\nMore attribute access for new-style classes\n-------------------------------------------\n\nThe following methods only apply to new-style classes.\n\nobject.__getattribute__(self, name)\n\n   Called unconditionally to implement attribute accesses for\n   instances of the class. If the class also defines\n   ``__getattr__()``, the latter will not be called unless\n   ``__getattribute__()`` either calls it explicitly or raises an\n   ``AttributeError``. This method should return the (computed)\n   attribute value or raise an ``AttributeError`` exception. In order\n   to avoid infinite recursion in this method, its implementation\n   should always call the base class method with the same name to\n   access any attributes it needs, for example,\n   ``object.__getattribute__(self, name)``.\n\n   Note: This method may still be bypassed when looking up special methods\n     as the result of implicit invocation via language syntax or\n     built-in functions. See *Special method lookup for new-style\n     classes*.\n\n\nImplementing Descriptors\n------------------------\n\nThe following methods only apply when an instance of the class\ncontaining the method (a so-called *descriptor* class) appears in an\n*owner* class (the descriptor must be in either the owner\'s class\ndictionary or in the class dictionary for one of its parents).  In the\nexamples below, "the attribute" refers to the attribute whose name is\nthe key of the property in the owner class\' ``__dict__``.\n\nobject.__get__(self, instance, owner)\n\n   Called to get the attribute of the owner class (class attribute\n   access) or of an instance of that class (instance attribute\n   access). *owner* is always the owner class, while *instance* is the\n   instance that the attribute was accessed through, or ``None`` when\n   the attribute is accessed through the *owner*.  This method should\n   return the (computed) attribute value or raise an\n   ``AttributeError`` exception.\n\nobject.__set__(self, instance, value)\n\n   Called to set the attribute on an instance *instance* of the owner\n   class to a new value, *value*.\n\nobject.__delete__(self, instance)\n\n   Called to delete the attribute on an instance *instance* of the\n   owner class.\n\n\nInvoking Descriptors\n--------------------\n\nIn general, a descriptor is an object attribute with "binding\nbehavior", one whose attribute access has been overridden by methods\nin the descriptor protocol:  ``__get__()``, ``__set__()``, and\n``__delete__()``. If any of those methods are defined for an object,\nit is said to be a descriptor.\n\nThe default behavior for attribute access is to get, set, or delete\nthe attribute from an object\'s dictionary. For instance, ``a.x`` has a\nlookup chain starting with ``a.__dict__[\'x\']``, then\n``type(a).__dict__[\'x\']``, and continuing through the base classes of\n``type(a)`` excluding metaclasses.\n\nHowever, if the looked-up value is an object defining one of the\ndescriptor methods, then Python may override the default behavior and\ninvoke the descriptor method instead.  Where this occurs in the\nprecedence chain depends on which descriptor methods were defined and\nhow they were called.  Note that descriptors are only invoked for new\nstyle objects or classes (ones that subclass ``object()`` or\n``type()``).\n\nThe starting point for descriptor invocation is a binding, ``a.x``.\nHow the arguments are assembled depends on ``a``:\n\nDirect Call\n   The simplest and least common call is when user code directly\n   invokes a descriptor method:    ``x.__get__(a)``.\n\nInstance Binding\n   If binding to a new-style object instance, ``a.x`` is transformed\n   into the call: ``type(a).__dict__[\'x\'].__get__(a, type(a))``.\n\nClass Binding\n   If binding to a new-style class, ``A.x`` is transformed into the\n   call: ``A.__dict__[\'x\'].__get__(None, A)``.\n\nSuper Binding\n   If ``a`` is an instance of ``super``, then the binding ``super(B,\n   obj).m()`` searches ``obj.__class__.__mro__`` for the base class\n   ``A`` immediately preceding ``B`` and then invokes the descriptor\n   with the call: ``A.__dict__[\'m\'].__get__(obj, obj.__class__)``.\n\nFor instance bindings, the precedence of descriptor invocation depends\non the which descriptor methods are defined.  A descriptor can define\nany combination of ``__get__()``, ``__set__()`` and ``__delete__()``.\nIf it does not define ``__get__()``, then accessing the attribute will\nreturn the descriptor object itself unless there is a value in the\nobject\'s instance dictionary.  If the descriptor defines ``__set__()``\nand/or ``__delete__()``, it is a data descriptor; if it defines\nneither, it is a non-data descriptor.  Normally, data descriptors\ndefine both ``__get__()`` and ``__set__()``, while non-data\ndescriptors have just the ``__get__()`` method.  Data descriptors with\n``__set__()`` and ``__get__()`` defined always override a redefinition\nin an instance dictionary.  In contrast, non-data descriptors can be\noverridden by instances.\n\nPython methods (including ``staticmethod()`` and ``classmethod()``)\nare implemented as non-data descriptors.  Accordingly, instances can\nredefine and override methods.  This allows individual instances to\nacquire behaviors that differ from other instances of the same class.\n\nThe ``property()`` function is implemented as a data descriptor.\nAccordingly, instances cannot override the behavior of a property.\n\n\n__slots__\n---------\n\nBy default, instances of both old and new-style classes have a\ndictionary for attribute storage.  This wastes space for objects\nhaving very few instance variables.  The space consumption can become\nacute when creating large numbers of instances.\n\nThe default can be overridden by defining *__slots__* in a new-style\nclass definition.  The *__slots__* declaration takes a sequence of\ninstance variables and reserves just enough space in each instance to\nhold a value for each variable.  Space is saved because *__dict__* is\nnot created for each instance.\n\n__slots__\n\n   This class variable can be assigned a string, iterable, or sequence\n   of strings with variable names used by instances.  If defined in a\n   new-style class, *__slots__* reserves space for the declared\n   variables and prevents the automatic creation of *__dict__* and\n   *__weakref__* for each instance.\n\n   New in version 2.2.\n\nNotes on using *__slots__*\n\n* When inheriting from a class without *__slots__*, the *__dict__*\n  attribute of that class will always be accessible, so a *__slots__*\n  definition in the subclass is meaningless.\n\n* Without a *__dict__* variable, instances cannot be assigned new\n  variables not listed in the *__slots__* definition.  Attempts to\n  assign to an unlisted variable name raises ``AttributeError``. If\n  dynamic assignment of new variables is desired, then add\n  ``\'__dict__\'`` to the sequence of strings in the *__slots__*\n  declaration.\n\n  Changed in version 2.3: Previously, adding ``\'__dict__\'`` to the\n  *__slots__* declaration would not enable the assignment of new\n  attributes not specifically listed in the sequence of instance\n  variable names.\n\n* Without a *__weakref__* variable for each instance, classes defining\n  *__slots__* do not support weak references to its instances. If weak\n  reference support is needed, then add ``\'__weakref__\'`` to the\n  sequence of strings in the *__slots__* declaration.\n\n  Changed in version 2.3: Previously, adding ``\'__weakref__\'`` to the\n  *__slots__* declaration would not enable support for weak\n  references.\n\n* *__slots__* are implemented at the class level by creating\n  descriptors (*Implementing Descriptors*) for each variable name.  As\n  a result, class attributes cannot be used to set default values for\n  instance variables defined by *__slots__*; otherwise, the class\n  attribute would overwrite the descriptor assignment.\n\n* The action of a *__slots__* declaration is limited to the class\n  where it is defined.  As a result, subclasses will have a *__dict__*\n  unless they also define *__slots__* (which must only contain names\n  of any *additional* slots).\n\n* If a class defines a slot also defined in a base class, the instance\n  variable defined by the base class slot is inaccessible (except by\n  retrieving its descriptor directly from the base class). This\n  renders the meaning of the program undefined.  In the future, a\n  check may be added to prevent this.\n\n* Nonempty *__slots__* does not work for classes derived from\n  "variable-length" built-in types such as ``long``, ``str`` and\n  ``tuple``.\n\n* Any non-string iterable may be assigned to *__slots__*. Mappings may\n  also be used; however, in the future, special meaning may be\n  assigned to the values corresponding to each key.\n\n* *__class__* assignment works only if both classes have the same\n  *__slots__*.\n\n  Changed in version 2.6: Previously, *__class__* assignment raised an\n  error if either new or old class had *__slots__*.\n\n\nCustomizing class creation\n==========================\n\nBy default, new-style classes are constructed using ``type()``. A\nclass definition is read into a separate namespace and the value of\nclass name is bound to the result of ``type(name, bases, dict)``.\n\nWhen the class definition is read, if *__metaclass__* is defined then\nthe callable assigned to it will be called instead of ``type()``. This\nallows classes or functions to be written which monitor or alter the\nclass creation process:\n\n* Modifying the class dictionary prior to the class being created.\n\n* Returning an instance of another class -- essentially performing the\n  role of a factory function.\n\nThese steps will have to be performed in the metaclass\'s ``__new__()``\nmethod -- ``type.__new__()`` can then be called from this method to\ncreate a class with different properties.  This example adds a new\nelement to the class dictionary before creating the class:\n\n   class metacls(type):\n       def __new__(mcs, name, bases, dict):\n           dict[\'foo\'] = \'metacls was here\'\n           return type.__new__(mcs, name, bases, dict)\n\nYou can of course also override other class methods (or add new\nmethods); for example defining a custom ``__call__()`` method in the\nmetaclass allows custom behavior when the class is called, e.g. not\nalways creating a new instance.\n\n__metaclass__\n\n   This variable can be any callable accepting arguments for ``name``,\n   ``bases``, and ``dict``.  Upon class creation, the callable is used\n   instead of the built-in ``type()``.\n\n   New in version 2.2.\n\nThe appropriate metaclass is determined by the following precedence\nrules:\n\n* If ``dict[\'__metaclass__\']`` exists, it is used.\n\n* Otherwise, if there is at least one base class, its metaclass is\n  used (this looks for a *__class__* attribute first and if not found,\n  uses its type).\n\n* Otherwise, if a global variable named __metaclass__ exists, it is\n  used.\n\n* Otherwise, the old-style, classic metaclass (types.ClassType) is\n  used.\n\nThe potential uses for metaclasses are boundless. Some ideas that have\nbeen explored including logging, interface checking, automatic\ndelegation, automatic property creation, proxies, frameworks, and\nautomatic resource locking/synchronization.\n\n\nCustomizing instance and subclass checks\n========================================\n\nNew in version 2.6.\n\nThe following methods are used to override the default behavior of the\n``isinstance()`` and ``issubclass()`` built-in functions.\n\nIn particular, the metaclass ``abc.ABCMeta`` implements these methods\nin order to allow the addition of Abstract Base Classes (ABCs) as\n"virtual base classes" to any class or type (including built-in\ntypes), including other ABCs.\n\nclass.__instancecheck__(self, instance)\n\n   Return true if *instance* should be considered a (direct or\n   indirect) instance of *class*. If defined, called to implement\n   ``isinstance(instance, class)``.\n\nclass.__subclasscheck__(self, subclass)\n\n   Return true if *subclass* should be considered a (direct or\n   indirect) subclass of *class*.  If defined, called to implement\n   ``issubclass(subclass, class)``.\n\nNote that these methods are looked up on the type (metaclass) of a\nclass.  They cannot be defined as class methods in the actual class.\nThis is consistent with the lookup of special methods that are called\non instances, only in this case the instance is itself a class.\n\nSee also:\n\n   **PEP 3119** - Introducing Abstract Base Classes\n      Includes the specification for customizing ``isinstance()`` and\n      ``issubclass()`` behavior through ``__instancecheck__()`` and\n      ``__subclasscheck__()``, with motivation for this functionality\n      in the context of adding Abstract Base Classes (see the ``abc``\n      module) to the language.\n\n\nEmulating callable objects\n==========================\n\nobject.__call__(self[, args...])\n\n   Called when the instance is "called" as a function; if this method\n   is defined, ``x(arg1, arg2, ...)`` is a shorthand for\n   ``x.__call__(arg1, arg2, ...)``.\n\n\nEmulating container types\n=========================\n\nThe following methods can be defined to implement container objects.\nContainers usually are sequences (such as lists or tuples) or mappings\n(like dictionaries), but can represent other containers as well.  The\nfirst set of methods is used either to emulate a sequence or to\nemulate a mapping; the difference is that for a sequence, the\nallowable keys should be the integers *k* for which ``0 <= k < N``\nwhere *N* is the length of the sequence, or slice objects, which\ndefine a range of items. (For backwards compatibility, the method\n``__getslice__()`` (see below) can also be defined to handle simple,\nbut not extended slices.) It is also recommended that mappings provide\nthe methods ``keys()``, ``values()``, ``items()``, ``has_key()``,\n``get()``, ``clear()``, ``setdefault()``, ``iterkeys()``,\n``itervalues()``, ``iteritems()``, ``pop()``, ``popitem()``,\n``copy()``, and ``update()`` behaving similar to those for Python\'s\nstandard dictionary objects.  The ``UserDict`` module provides a\n``DictMixin`` class to help create those methods from a base set of\n``__getitem__()``, ``__setitem__()``, ``__delitem__()``, and\n``keys()``. Mutable sequences should provide methods ``append()``,\n``count()``, ``index()``, ``extend()``, ``insert()``, ``pop()``,\n``remove()``, ``reverse()`` and ``sort()``, like Python standard list\nobjects.  Finally, sequence types should implement addition (meaning\nconcatenation) and multiplication (meaning repetition) by defining the\nmethods ``__add__()``, ``__radd__()``, ``__iadd__()``, ``__mul__()``,\n``__rmul__()`` and ``__imul__()`` described below; they should not\ndefine ``__coerce__()`` or other numerical operators.  It is\nrecommended that both mappings and sequences implement the\n``__contains__()`` method to allow efficient use of the ``in``\noperator; for mappings, ``in`` should be equivalent of ``has_key()``;\nfor sequences, it should search through the values.  It is further\nrecommended that both mappings and sequences implement the\n``__iter__()`` method to allow efficient iteration through the\ncontainer; for mappings, ``__iter__()`` should be the same as\n``iterkeys()``; for sequences, it should iterate through the values.\n\nobject.__len__(self)\n\n   Called to implement the built-in function ``len()``.  Should return\n   the length of the object, an integer ``>=`` 0.  Also, an object\n   that doesn\'t define a ``__nonzero__()`` method and whose\n   ``__len__()`` method returns zero is considered to be false in a\n   Boolean context.\n\nobject.__getitem__(self, key)\n\n   Called to implement evaluation of ``self[key]``. For sequence\n   types, the accepted keys should be integers and slice objects.\n   Note that the special interpretation of negative indexes (if the\n   class wishes to emulate a sequence type) is up to the\n   ``__getitem__()`` method. If *key* is of an inappropriate type,\n   ``TypeError`` may be raised; if of a value outside the set of\n   indexes for the sequence (after any special interpretation of\n   negative values), ``IndexError`` should be raised. For mapping\n   types, if *key* is missing (not in the container), ``KeyError``\n   should be raised.\n\n   Note: ``for`` loops expect that an ``IndexError`` will be raised for\n     illegal indexes to allow proper detection of the end of the\n     sequence.\n\nobject.__setitem__(self, key, value)\n\n   Called to implement assignment to ``self[key]``.  Same note as for\n   ``__getitem__()``.  This should only be implemented for mappings if\n   the objects support changes to the values for keys, or if new keys\n   can be added, or for sequences if elements can be replaced.  The\n   same exceptions should be raised for improper *key* values as for\n   the ``__getitem__()`` method.\n\nobject.__delitem__(self, key)\n\n   Called to implement deletion of ``self[key]``.  Same note as for\n   ``__getitem__()``.  This should only be implemented for mappings if\n   the objects support removal of keys, or for sequences if elements\n   can be removed from the sequence.  The same exceptions should be\n   raised for improper *key* values as for the ``__getitem__()``\n   method.\n\nobject.__iter__(self)\n\n   This method is called when an iterator is required for a container.\n   This method should return a new iterator object that can iterate\n   over all the objects in the container.  For mappings, it should\n   iterate over the keys of the container, and should also be made\n   available as the method ``iterkeys()``.\n\n   Iterator objects also need to implement this method; they are\n   required to return themselves.  For more information on iterator\n   objects, see *Iterator Types*.\n\nobject.__reversed__(self)\n\n   Called (if present) by the ``reversed()`` built-in to implement\n   reverse iteration.  It should return a new iterator object that\n   iterates over all the objects in the container in reverse order.\n\n   If the ``__reversed__()`` method is not provided, the\n   ``reversed()`` built-in will fall back to using the sequence\n   protocol (``__len__()`` and ``__getitem__()``).  Objects that\n   support the sequence protocol should only provide\n   ``__reversed__()`` if they can provide an implementation that is\n   more efficient than the one provided by ``reversed()``.\n\n   New in version 2.6.\n\nThe membership test operators (``in`` and ``not in``) are normally\nimplemented as an iteration through a sequence.  However, container\nobjects can supply the following special method with a more efficient\nimplementation, which also does not require the object be a sequence.\n\nobject.__contains__(self, item)\n\n   Called to implement membership test operators.  Should return true\n   if *item* is in *self*, false otherwise.  For mapping objects, this\n   should consider the keys of the mapping rather than the values or\n   the key-item pairs.\n\n   For objects that don\'t define ``__contains__()``, the membership\n   test first tries iteration via ``__iter__()``, then the old\n   sequence iteration protocol via ``__getitem__()``, see *this\n   section in the language reference*.\n\n\nAdditional methods for emulation of sequence types\n==================================================\n\nThe following optional methods can be defined to further emulate\nsequence objects.  Immutable sequences methods should at most only\ndefine ``__getslice__()``; mutable sequences might define all three\nmethods.\n\nobject.__getslice__(self, i, j)\n\n   Deprecated since version 2.0: Support slice objects as parameters\n   to the ``__getitem__()`` method. (However, built-in types in\n   CPython currently still implement ``__getslice__()``.  Therefore,\n   you have to override it in derived classes when implementing\n   slicing.)\n\n   Called to implement evaluation of ``self[i:j]``. The returned\n   object should be of the same type as *self*.  Note that missing *i*\n   or *j* in the slice expression are replaced by zero or\n   ``sys.maxint``, respectively.  If negative indexes are used in the\n   slice, the length of the sequence is added to that index. If the\n   instance does not implement the ``__len__()`` method, an\n   ``AttributeError`` is raised. No guarantee is made that indexes\n   adjusted this way are not still negative.  Indexes which are\n   greater than the length of the sequence are not modified. If no\n   ``__getslice__()`` is found, a slice object is created instead, and\n   passed to ``__getitem__()`` instead.\n\nobject.__setslice__(self, i, j, sequence)\n\n   Called to implement assignment to ``self[i:j]``. Same notes for *i*\n   and *j* as for ``__getslice__()``.\n\n   This method is deprecated. If no ``__setslice__()`` is found, or\n   for extended slicing of the form ``self[i:j:k]``, a slice object is\n   created, and passed to ``__setitem__()``, instead of\n   ``__setslice__()`` being called.\n\nobject.__delslice__(self, i, j)\n\n   Called to implement deletion of ``self[i:j]``. Same notes for *i*\n   and *j* as for ``__getslice__()``. This method is deprecated. If no\n   ``__delslice__()`` is found, or for extended slicing of the form\n   ``self[i:j:k]``, a slice object is created, and passed to\n   ``__delitem__()``, instead of ``__delslice__()`` being called.\n\nNotice that these methods are only invoked when a single slice with a\nsingle colon is used, and the slice method is available.  For slice\noperations involving extended slice notation, or in absence of the\nslice methods, ``__getitem__()``, ``__setitem__()`` or\n``__delitem__()`` is called with a slice object as argument.\n\nThe following example demonstrate how to make your program or module\ncompatible with earlier versions of Python (assuming that methods\n``__getitem__()``, ``__setitem__()`` and ``__delitem__()`` support\nslice objects as arguments):\n\n   class MyClass:\n       ...\n       def __getitem__(self, index):\n           ...\n       def __setitem__(self, index, value):\n           ...\n       def __delitem__(self, index):\n           ...\n\n       if sys.version_info < (2, 0):\n           # They won\'t be defined if version is at least 2.0 final\n\n           def __getslice__(self, i, j):\n               return self[max(0, i):max(0, j):]\n           def __setslice__(self, i, j, seq):\n               self[max(0, i):max(0, j):] = seq\n           def __delslice__(self, i, j):\n               del self[max(0, i):max(0, j):]\n       ...\n\nNote the calls to ``max()``; these are necessary because of the\nhandling of negative indices before the ``__*slice__()`` methods are\ncalled.  When negative indexes are used, the ``__*item__()`` methods\nreceive them as provided, but the ``__*slice__()`` methods get a\n"cooked" form of the index values.  For each negative index value, the\nlength of the sequence is added to the index before calling the method\n(which may still result in a negative index); this is the customary\nhandling of negative indexes by the built-in sequence types, and the\n``__*item__()`` methods are expected to do this as well.  However,\nsince they should already be doing that, negative indexes cannot be\npassed in; they must be constrained to the bounds of the sequence\nbefore being passed to the ``__*item__()`` methods. Calling ``max(0,\ni)`` conveniently returns the proper value.\n\n\nEmulating numeric types\n=======================\n\nThe following methods can be defined to emulate numeric objects.\nMethods corresponding to operations that are not supported by the\nparticular kind of number implemented (e.g., bitwise operations for\nnon-integral numbers) should be left undefined.\n\nobject.__add__(self, other)\nobject.__sub__(self, other)\nobject.__mul__(self, other)\nobject.__floordiv__(self, other)\nobject.__mod__(self, other)\nobject.__divmod__(self, other)\nobject.__pow__(self, other[, modulo])\nobject.__lshift__(self, other)\nobject.__rshift__(self, other)\nobject.__and__(self, other)\nobject.__xor__(self, other)\nobject.__or__(self, other)\n\n   These methods are called to implement the binary arithmetic\n   operations (``+``, ``-``, ``*``, ``//``, ``%``, ``divmod()``,\n   ``pow()``, ``**``, ``<<``, ``>>``, ``&``, ``^``, ``|``).  For\n   instance, to evaluate the expression ``x + y``, where *x* is an\n   instance of a class that has an ``__add__()`` method,\n   ``x.__add__(y)`` is called.  The ``__divmod__()`` method should be\n   the equivalent to using ``__floordiv__()`` and ``__mod__()``; it\n   should not be related to ``__truediv__()`` (described below).  Note\n   that ``__pow__()`` should be defined to accept an optional third\n   argument if the ternary version of the built-in ``pow()`` function\n   is to be supported.\n\n   If one of those methods does not support the operation with the\n   supplied arguments, it should return ``NotImplemented``.\n\nobject.__div__(self, other)\nobject.__truediv__(self, other)\n\n   The division operator (``/``) is implemented by these methods.  The\n   ``__truediv__()`` method is used when ``__future__.division`` is in\n   effect, otherwise ``__div__()`` is used.  If only one of these two\n   methods is defined, the object will not support division in the\n   alternate context; ``TypeError`` will be raised instead.\n\nobject.__radd__(self, other)\nobject.__rsub__(self, other)\nobject.__rmul__(self, other)\nobject.__rdiv__(self, other)\nobject.__rtruediv__(self, other)\nobject.__rfloordiv__(self, other)\nobject.__rmod__(self, other)\nobject.__rdivmod__(self, other)\nobject.__rpow__(self, other)\nobject.__rlshift__(self, other)\nobject.__rrshift__(self, other)\nobject.__rand__(self, other)\nobject.__rxor__(self, other)\nobject.__ror__(self, other)\n\n   These methods are called to implement the binary arithmetic\n   operations (``+``, ``-``, ``*``, ``/``, ``%``, ``divmod()``,\n   ``pow()``, ``**``, ``<<``, ``>>``, ``&``, ``^``, ``|``) with\n   reflected (swapped) operands.  These functions are only called if\n   the left operand does not support the corresponding operation and\n   the operands are of different types. [2] For instance, to evaluate\n   the expression ``x - y``, where *y* is an instance of a class that\n   has an ``__rsub__()`` method, ``y.__rsub__(x)`` is called if\n   ``x.__sub__(y)`` returns *NotImplemented*.\n\n   Note that ternary ``pow()`` will not try calling ``__rpow__()``\n   (the coercion rules would become too complicated).\n\n   Note: If the right operand\'s type is a subclass of the left operand\'s\n     type and that subclass provides the reflected method for the\n     operation, this method will be called before the left operand\'s\n     non-reflected method.  This behavior allows subclasses to\n     override their ancestors\' operations.\n\nobject.__iadd__(self, other)\nobject.__isub__(self, other)\nobject.__imul__(self, other)\nobject.__idiv__(self, other)\nobject.__itruediv__(self, other)\nobject.__ifloordiv__(self, other)\nobject.__imod__(self, other)\nobject.__ipow__(self, other[, modulo])\nobject.__ilshift__(self, other)\nobject.__irshift__(self, other)\nobject.__iand__(self, other)\nobject.__ixor__(self, other)\nobject.__ior__(self, other)\n\n   These methods are called to implement the augmented arithmetic\n   assignments (``+=``, ``-=``, ``*=``, ``/=``, ``//=``, ``%=``,\n   ``**=``, ``<<=``, ``>>=``, ``&=``, ``^=``, ``|=``).  These methods\n   should attempt to do the operation in-place (modifying *self*) and\n   return the result (which could be, but does not have to be,\n   *self*).  If a specific method is not defined, the augmented\n   assignment falls back to the normal methods.  For instance, to\n   execute the statement ``x += y``, where *x* is an instance of a\n   class that has an ``__iadd__()`` method, ``x.__iadd__(y)`` is\n   called.  If *x* is an instance of a class that does not define a\n   ``__iadd__()`` method, ``x.__add__(y)`` and ``y.__radd__(x)`` are\n   considered, as with the evaluation of ``x + y``.\n\nobject.__neg__(self)\nobject.__pos__(self)\nobject.__abs__(self)\nobject.__invert__(self)\n\n   Called to implement the unary arithmetic operations (``-``, ``+``,\n   ``abs()`` and ``~``).\n\nobject.__complex__(self)\nobject.__int__(self)\nobject.__long__(self)\nobject.__float__(self)\n\n   Called to implement the built-in functions ``complex()``,\n   ``int()``, ``long()``, and ``float()``.  Should return a value of\n   the appropriate type.\n\nobject.__oct__(self)\nobject.__hex__(self)\n\n   Called to implement the built-in functions ``oct()`` and ``hex()``.\n   Should return a string value.\n\nobject.__index__(self)\n\n   Called to implement ``operator.index()``.  Also called whenever\n   Python needs an integer object (such as in slicing).  Must return\n   an integer (int or long).\n\n   New in version 2.5.\n\nobject.__coerce__(self, other)\n\n   Called to implement "mixed-mode" numeric arithmetic.  Should either\n   return a 2-tuple containing *self* and *other* converted to a\n   common numeric type, or ``None`` if conversion is impossible.  When\n   the common type would be the type of ``other``, it is sufficient to\n   return ``None``, since the interpreter will also ask the other\n   object to attempt a coercion (but sometimes, if the implementation\n   of the other type cannot be changed, it is useful to do the\n   conversion to the other type here).  A return value of\n   ``NotImplemented`` is equivalent to returning ``None``.\n\n\nCoercion rules\n==============\n\nThis section used to document the rules for coercion.  As the language\nhas evolved, the coercion rules have become hard to document\nprecisely; documenting what one version of one particular\nimplementation does is undesirable.  Instead, here are some informal\nguidelines regarding coercion.  In Python 3, coercion will not be\nsupported.\n\n* If the left operand of a % operator is a string or Unicode object,\n  no coercion takes place and the string formatting operation is\n  invoked instead.\n\n* It is no longer recommended to define a coercion operation. Mixed-\n  mode operations on types that don\'t define coercion pass the\n  original arguments to the operation.\n\n* New-style classes (those derived from ``object``) never invoke the\n  ``__coerce__()`` method in response to a binary operator; the only\n  time ``__coerce__()`` is invoked is when the built-in function\n  ``coerce()`` is called.\n\n* For most intents and purposes, an operator that returns\n  ``NotImplemented`` is treated the same as one that is not\n  implemented at all.\n\n* Below, ``__op__()`` and ``__rop__()`` are used to signify the\n  generic method names corresponding to an operator; ``__iop__()`` is\n  used for the corresponding in-place operator.  For example, for the\n  operator \'``+``\', ``__add__()`` and ``__radd__()`` are used for the\n  left and right variant of the binary operator, and ``__iadd__()``\n  for the in-place variant.\n\n* For objects *x* and *y*, first ``x.__op__(y)`` is tried.  If this is\n  not implemented or returns ``NotImplemented``, ``y.__rop__(x)`` is\n  tried.  If this is also not implemented or returns\n  ``NotImplemented``, a ``TypeError`` exception is raised.  But see\n  the following exception:\n\n* Exception to the previous item: if the left operand is an instance\n  of a built-in type or a new-style class, and the right operand is an\n  instance of a proper subclass of that type or class and overrides\n  the base\'s ``__rop__()`` method, the right operand\'s ``__rop__()``\n  method is tried *before* the left operand\'s ``__op__()`` method.\n\n  This is done so that a subclass can completely override binary\n  operators. Otherwise, the left operand\'s ``__op__()`` method would\n  always accept the right operand: when an instance of a given class\n  is expected, an instance of a subclass of that class is always\n  acceptable.\n\n* When either operand type defines a coercion, this coercion is called\n  before that type\'s ``__op__()`` or ``__rop__()`` method is called,\n  but no sooner.  If the coercion returns an object of a different\n  type for the operand whose coercion is invoked, part of the process\n  is redone using the new object.\n\n* When an in-place operator (like \'``+=``\') is used, if the left\n  operand implements ``__iop__()``, it is invoked without any\n  coercion.  When the operation falls back to ``__op__()`` and/or\n  ``__rop__()``, the normal coercion rules apply.\n\n* In ``x + y``, if *x* is a sequence that implements sequence\n  concatenation, sequence concatenation is invoked.\n\n* In ``x * y``, if one operand is a sequence that implements sequence\n  repetition, and the other is an integer (``int`` or ``long``),\n  sequence repetition is invoked.\n\n* Rich comparisons (implemented by methods ``__eq__()`` and so on)\n  never use coercion.  Three-way comparison (implemented by\n  ``__cmp__()``) does use coercion under the same conditions as other\n  binary operations use it.\n\n* In the current implementation, the built-in numeric types ``int``,\n  ``long``, ``float``, and ``complex`` do not use coercion. All these\n  types implement a ``__coerce__()`` method, for use by the built-in\n  ``coerce()`` function.\n\n  Changed in version 2.7.\n\n\nWith Statement Context Managers\n===============================\n\nNew in version 2.5.\n\nA *context manager* is an object that defines the runtime context to\nbe established when executing a ``with`` statement. The context\nmanager handles the entry into, and the exit from, the desired runtime\ncontext for the execution of the block of code.  Context managers are\nnormally invoked using the ``with`` statement (described in section\n*The with statement*), but can also be used by directly invoking their\nmethods.\n\nTypical uses of context managers include saving and restoring various\nkinds of global state, locking and unlocking resources, closing opened\nfiles, etc.\n\nFor more information on context managers, see *Context Manager Types*.\n\nobject.__enter__(self)\n\n   Enter the runtime context related to this object. The ``with``\n   statement will bind this method\'s return value to the target(s)\n   specified in the ``as`` clause of the statement, if any.\n\nobject.__exit__(self, exc_type, exc_value, traceback)\n\n   Exit the runtime context related to this object. The parameters\n   describe the exception that caused the context to be exited. If the\n   context was exited without an exception, all three arguments will\n   be ``None``.\n\n   If an exception is supplied, and the method wishes to suppress the\n   exception (i.e., prevent it from being propagated), it should\n   return a true value. Otherwise, the exception will be processed\n   normally upon exit from this method.\n\n   Note that ``__exit__()`` methods should not reraise the passed-in\n   exception; this is the caller\'s responsibility.\n\nSee also:\n\n   **PEP 0343** - The "with" statement\n      The specification, background, and examples for the Python\n      ``with`` statement.\n\n\nSpecial method lookup for old-style classes\n===========================================\n\nFor old-style classes, special methods are always looked up in exactly\nthe same way as any other method or attribute. This is the case\nregardless of whether the method is being looked up explicitly as in\n``x.__getitem__(i)`` or implicitly as in ``x[i]``.\n\nThis behaviour means that special methods may exhibit different\nbehaviour for different instances of a single old-style class if the\nappropriate special attributes are set differently:\n\n   >>> class C:\n   ...     pass\n   ...\n   >>> c1 = C()\n   >>> c2 = C()\n   >>> c1.__len__ = lambda: 5\n   >>> c2.__len__ = lambda: 9\n   >>> len(c1)\n   5\n   >>> len(c2)\n   9\n\n\nSpecial method lookup for new-style classes\n===========================================\n\nFor new-style classes, implicit invocations of special methods are\nonly guaranteed to work correctly if defined on an object\'s type, not\nin the object\'s instance dictionary.  That behaviour is the reason why\nthe following code raises an exception (unlike the equivalent example\nwith old-style classes):\n\n   >>> class C(object):\n   ...     pass\n   ...\n   >>> c = C()\n   >>> c.__len__ = lambda: 5\n   >>> len(c)\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in <module>\n   TypeError: object of type \'C\' has no len()\n\nThe rationale behind this behaviour lies with a number of special\nmethods such as ``__hash__()`` and ``__repr__()`` that are implemented\nby all objects, including type objects. If the implicit lookup of\nthese methods used the conventional lookup process, they would fail\nwhen invoked on the type object itself:\n\n   >>> 1 .__hash__() == hash(1)\n   True\n   >>> int.__hash__() == hash(int)\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in <module>\n   TypeError: descriptor \'__hash__\' of \'int\' object needs an argument\n\nIncorrectly attempting to invoke an unbound method of a class in this\nway is sometimes referred to as \'metaclass confusion\', and is avoided\nby bypassing the instance when looking up special methods:\n\n   >>> type(1).__hash__(1) == hash(1)\n   True\n   >>> type(int).__hash__(int) == hash(int)\n   True\n\nIn addition to bypassing any instance attributes in the interest of\ncorrectness, implicit special method lookup generally also bypasses\nthe ``__getattribute__()`` method even of the object\'s metaclass:\n\n   >>> class Meta(type):\n   ...    def __getattribute__(*args):\n   ...       print "Metaclass getattribute invoked"\n   ...       return type.__getattribute__(*args)\n   ...\n   >>> class C(object):\n   ...     __metaclass__ = Meta\n   ...     def __len__(self):\n   ...         return 10\n   ...     def __getattribute__(*args):\n   ...         print "Class getattribute invoked"\n   ...         return object.__getattribute__(*args)\n   ...\n   >>> c = C()\n   >>> c.__len__()                 # Explicit lookup via instance\n   Class getattribute invoked\n   10\n   >>> type(c).__len__(c)          # Explicit lookup via type\n   Metaclass getattribute invoked\n   10\n   >>> len(c)                      # Implicit lookup\n   10\n\nBypassing the ``__getattribute__()`` machinery in this fashion\nprovides significant scope for speed optimisations within the\ninterpreter, at the cost of some flexibility in the handling of\nspecial methods (the special method *must* be set on the class object\nitself in order to be consistently invoked by the interpreter).\n\n-[ Footnotes ]-\n\n[1] It *is* possible in some cases to change an object\'s type, under\n    certain controlled conditions. It generally isn\'t a good idea\n    though, since it can lead to some very strange behaviour if it is\n    handled incorrectly.\n\n[2] For operands of the same type, it is assumed that if the non-\n    reflected method (such as ``__add__()``) fails the operation is\n    not supported, which is why the reflected method is not called.\n',
- 'string-methods': '\nString Methods\n**************\n\nBelow are listed the string methods which both 8-bit strings and\nUnicode objects support.  Some of them are also available on\n``bytearray`` objects.\n\nIn addition, Python\'s strings support the sequence type methods\ndescribed in the *Sequence Types --- str, unicode, list, tuple,\nbytearray, buffer, xrange* section. To output formatted strings use\ntemplate strings or the ``%`` operator described in the *String\nFormatting Operations* section. Also, see the ``re`` module for string\nfunctions based on regular expressions.\n\nstr.capitalize()\n\n   Return a copy of the string with its first character capitalized\n   and the rest lowercased.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.center(width[, fillchar])\n\n   Return centered in a string of length *width*. Padding is done\n   using the specified *fillchar* (default is a space).\n\n   Changed in version 2.4: Support for the *fillchar* argument.\n\nstr.count(sub[, start[, end]])\n\n   Return the number of non-overlapping occurrences of substring *sub*\n   in the range [*start*, *end*].  Optional arguments *start* and\n   *end* are interpreted as in slice notation.\n\nstr.decode([encoding[, errors]])\n\n   Decodes the string using the codec registered for *encoding*.\n   *encoding* defaults to the default string encoding.  *errors* may\n   be given to set a different error handling scheme.  The default is\n   ``\'strict\'``, meaning that encoding errors raise ``UnicodeError``.\n   Other possible values are ``\'ignore\'``, ``\'replace\'`` and any other\n   name registered via ``codecs.register_error()``, see section *Codec\n   Base Classes*.\n\n   New in version 2.2.\n\n   Changed in version 2.3: Support for other error handling schemes\n   added.\n\n   Changed in version 2.7: Support for keyword arguments added.\n\nstr.encode([encoding[, errors]])\n\n   Return an encoded version of the string.  Default encoding is the\n   current default string encoding.  *errors* may be given to set a\n   different error handling scheme.  The default for *errors* is\n   ``\'strict\'``, meaning that encoding errors raise a\n   ``UnicodeError``.  Other possible values are ``\'ignore\'``,\n   ``\'replace\'``, ``\'xmlcharrefreplace\'``, ``\'backslashreplace\'`` and\n   any other name registered via ``codecs.register_error()``, see\n   section *Codec Base Classes*. For a list of possible encodings, see\n   section *Standard Encodings*.\n\n   New in version 2.0.\n\n   Changed in version 2.3: Support for ``\'xmlcharrefreplace\'`` and\n   ``\'backslashreplace\'`` and other error handling schemes added.\n\n   Changed in version 2.7: Support for keyword arguments added.\n\nstr.endswith(suffix[, start[, end]])\n\n   Return ``True`` if the string ends with the specified *suffix*,\n   otherwise return ``False``.  *suffix* can also be a tuple of\n   suffixes to look for.  With optional *start*, test beginning at\n   that position.  With optional *end*, stop comparing at that\n   position.\n\n   Changed in version 2.5: Accept tuples as *suffix*.\n\nstr.expandtabs([tabsize])\n\n   Return a copy of the string where all tab characters are replaced\n   by one or more spaces, depending on the current column and the\n   given tab size.  Tab positions occur every *tabsize* characters\n   (default is 8, giving tab positions at columns 0, 8, 16 and so on).\n   To expand the string, the current column is set to zero and the\n   string is examined character by character.  If the character is a\n   tab (``\\t``), one or more space characters are inserted in the\n   result until the current column is equal to the next tab position.\n   (The tab character itself is not copied.)  If the character is a\n   newline (``\\n``) or return (``\\r``), it is copied and the current\n   column is reset to zero.  Any other character is copied unchanged\n   and the current column is incremented by one regardless of how the\n   character is represented when printed.\n\n   >>> \'01\\t012\\t0123\\t01234\'.expandtabs()\n   \'01      012     0123    01234\'\n   >>> \'01\\t012\\t0123\\t01234\'.expandtabs(4)\n   \'01  012 0123    01234\'\n\nstr.find(sub[, start[, end]])\n\n   Return the lowest index in the string where substring *sub* is\n   found, such that *sub* is contained in the slice ``s[start:end]``.\n   Optional arguments *start* and *end* are interpreted as in slice\n   notation.  Return ``-1`` if *sub* is not found.\n\n   Note: The ``find()`` method should be used only if you need to know the\n     position of *sub*.  To check if *sub* is a substring or not, use\n     the ``in`` operator:\n\n        >>> \'Py\' in \'Python\'\n        True\n\nstr.format(*args, **kwargs)\n\n   Perform a string formatting operation.  The string on which this\n   method is called can contain literal text or replacement fields\n   delimited by braces ``{}``.  Each replacement field contains either\n   the numeric index of a positional argument, or the name of a\n   keyword argument.  Returns a copy of the string where each\n   replacement field is replaced with the string value of the\n   corresponding argument.\n\n   >>> "The sum of 1 + 2 is {0}".format(1+2)\n   \'The sum of 1 + 2 is 3\'\n\n   See *Format String Syntax* for a description of the various\n   formatting options that can be specified in format strings.\n\n   This method of string formatting is the new standard in Python 3,\n   and should be preferred to the ``%`` formatting described in\n   *String Formatting Operations* in new code.\n\n   New in version 2.6.\n\nstr.index(sub[, start[, end]])\n\n   Like ``find()``, but raise ``ValueError`` when the substring is not\n   found.\n\nstr.isalnum()\n\n   Return true if all characters in the string are alphanumeric and\n   there is at least one character, false otherwise.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.isalpha()\n\n   Return true if all characters in the string are alphabetic and\n   there is at least one character, false otherwise.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.isdigit()\n\n   Return true if all characters in the string are digits and there is\n   at least one character, false otherwise.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.islower()\n\n   Return true if all cased characters [4] in the string are lowercase\n   and there is at least one cased character, false otherwise.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.isspace()\n\n   Return true if there are only whitespace characters in the string\n   and there is at least one character, false otherwise.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.istitle()\n\n   Return true if the string is a titlecased string and there is at\n   least one character, for example uppercase characters may only\n   follow uncased characters and lowercase characters only cased ones.\n   Return false otherwise.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.isupper()\n\n   Return true if all cased characters [4] in the string are uppercase\n   and there is at least one cased character, false otherwise.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.join(iterable)\n\n   Return a string which is the concatenation of the strings in the\n   *iterable* *iterable*.  The separator between elements is the\n   string providing this method.\n\nstr.ljust(width[, fillchar])\n\n   Return the string left justified in a string of length *width*.\n   Padding is done using the specified *fillchar* (default is a\n   space).  The original string is returned if *width* is less than or\n   equal to ``len(s)``.\n\n   Changed in version 2.4: Support for the *fillchar* argument.\n\nstr.lower()\n\n   Return a copy of the string with all the cased characters [4]\n   converted to lowercase.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.lstrip([chars])\n\n   Return a copy of the string with leading characters removed.  The\n   *chars* argument is a string specifying the set of characters to be\n   removed.  If omitted or ``None``, the *chars* argument defaults to\n   removing whitespace.  The *chars* argument is not a prefix; rather,\n   all combinations of its values are stripped:\n\n   >>> \'   spacious   \'.lstrip()\n   \'spacious   \'\n   >>> \'www.example.com\'.lstrip(\'cmowz.\')\n   \'example.com\'\n\n   Changed in version 2.2.2: Support for the *chars* argument.\n\nstr.partition(sep)\n\n   Split the string at the first occurrence of *sep*, and return a\n   3-tuple containing the part before the separator, the separator\n   itself, and the part after the separator.  If the separator is not\n   found, return a 3-tuple containing the string itself, followed by\n   two empty strings.\n\n   New in version 2.5.\n\nstr.replace(old, new[, count])\n\n   Return a copy of the string with all occurrences of substring *old*\n   replaced by *new*.  If the optional argument *count* is given, only\n   the first *count* occurrences are replaced.\n\nstr.rfind(sub[, start[, end]])\n\n   Return the highest index in the string where substring *sub* is\n   found, such that *sub* is contained within ``s[start:end]``.\n   Optional arguments *start* and *end* are interpreted as in slice\n   notation.  Return ``-1`` on failure.\n\nstr.rindex(sub[, start[, end]])\n\n   Like ``rfind()`` but raises ``ValueError`` when the substring *sub*\n   is not found.\n\nstr.rjust(width[, fillchar])\n\n   Return the string right justified in a string of length *width*.\n   Padding is done using the specified *fillchar* (default is a\n   space). The original string is returned if *width* is less than or\n   equal to ``len(s)``.\n\n   Changed in version 2.4: Support for the *fillchar* argument.\n\nstr.rpartition(sep)\n\n   Split the string at the last occurrence of *sep*, and return a\n   3-tuple containing the part before the separator, the separator\n   itself, and the part after the separator.  If the separator is not\n   found, return a 3-tuple containing two empty strings, followed by\n   the string itself.\n\n   New in version 2.5.\n\nstr.rsplit([sep[, maxsplit]])\n\n   Return a list of the words in the string, using *sep* as the\n   delimiter string. If *maxsplit* is given, at most *maxsplit* splits\n   are done, the *rightmost* ones.  If *sep* is not specified or\n   ``None``, any whitespace string is a separator.  Except for\n   splitting from the right, ``rsplit()`` behaves like ``split()``\n   which is described in detail below.\n\n   New in version 2.4.\n\nstr.rstrip([chars])\n\n   Return a copy of the string with trailing characters removed.  The\n   *chars* argument is a string specifying the set of characters to be\n   removed.  If omitted or ``None``, the *chars* argument defaults to\n   removing whitespace.  The *chars* argument is not a suffix; rather,\n   all combinations of its values are stripped:\n\n   >>> \'   spacious   \'.rstrip()\n   \'   spacious\'\n   >>> \'mississippi\'.rstrip(\'ipz\')\n   \'mississ\'\n\n   Changed in version 2.2.2: Support for the *chars* argument.\n\nstr.split([sep[, maxsplit]])\n\n   Return a list of the words in the string, using *sep* as the\n   delimiter string.  If *maxsplit* is given, at most *maxsplit*\n   splits are done (thus, the list will have at most ``maxsplit+1``\n   elements).  If *maxsplit* is not specified or ``-1``, then there is\n   no limit on the number of splits (all possible splits are made).\n\n   If *sep* is given, consecutive delimiters are not grouped together\n   and are deemed to delimit empty strings (for example,\n   ``\'1,,2\'.split(\',\')`` returns ``[\'1\', \'\', \'2\']``).  The *sep*\n   argument may consist of multiple characters (for example,\n   ``\'1<>2<>3\'.split(\'<>\')`` returns ``[\'1\', \'2\', \'3\']``). Splitting\n   an empty string with a specified separator returns ``[\'\']``.\n\n   If *sep* is not specified or is ``None``, a different splitting\n   algorithm is applied: runs of consecutive whitespace are regarded\n   as a single separator, and the result will contain no empty strings\n   at the start or end if the string has leading or trailing\n   whitespace.  Consequently, splitting an empty string or a string\n   consisting of just whitespace with a ``None`` separator returns\n   ``[]``.\n\n   For example, ``\' 1  2   3  \'.split()`` returns ``[\'1\', \'2\', \'3\']``,\n   and ``\'  1  2   3  \'.split(None, 1)`` returns ``[\'1\', \'2   3  \']``.\n\nstr.splitlines([keepends])\n\n   Return a list of the lines in the string, breaking at line\n   boundaries. This method uses the *universal newlines* approach to\n   splitting lines. Line breaks are not included in the resulting list\n   unless *keepends* is given and true.\n\n   For example, ``\'ab c\\n\\nde fg\\rkl\\r\\n\'.splitlines()`` returns\n   ``[\'ab c\', \'\', \'de fg\', \'kl\']``, while the same call with\n   ``splitlines(True)`` returns ``[\'ab c\\n\', \'\\n\', \'de fg\\r\',\n   \'kl\\r\\n\']``.\n\n   Unlike ``split()`` when a delimiter string *sep* is given, this\n   method returns an empty list for the empty string, and a terminal\n   line break does not result in an extra line.\n\nstr.startswith(prefix[, start[, end]])\n\n   Return ``True`` if string starts with the *prefix*, otherwise\n   return ``False``. *prefix* can also be a tuple of prefixes to look\n   for.  With optional *start*, test string beginning at that\n   position.  With optional *end*, stop comparing string at that\n   position.\n\n   Changed in version 2.5: Accept tuples as *prefix*.\n\nstr.strip([chars])\n\n   Return a copy of the string with the leading and trailing\n   characters removed. The *chars* argument is a string specifying the\n   set of characters to be removed. If omitted or ``None``, the\n   *chars* argument defaults to removing whitespace. The *chars*\n   argument is not a prefix or suffix; rather, all combinations of its\n   values are stripped:\n\n   >>> \'   spacious   \'.strip()\n   \'spacious\'\n   >>> \'www.example.com\'.strip(\'cmowz.\')\n   \'example\'\n\n   Changed in version 2.2.2: Support for the *chars* argument.\n\nstr.swapcase()\n\n   Return a copy of the string with uppercase characters converted to\n   lowercase and vice versa.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.title()\n\n   Return a titlecased version of the string where words start with an\n   uppercase character and the remaining characters are lowercase.\n\n   The algorithm uses a simple language-independent definition of a\n   word as groups of consecutive letters.  The definition works in\n   many contexts but it means that apostrophes in contractions and\n   possessives form word boundaries, which may not be the desired\n   result:\n\n      >>> "they\'re bill\'s friends from the UK".title()\n      "They\'Re Bill\'S Friends From The Uk"\n\n   A workaround for apostrophes can be constructed using regular\n   expressions:\n\n      >>> import re\n      >>> def titlecase(s):\n      ...     return re.sub(r"[A-Za-z]+(\'[A-Za-z]+)?",\n      ...                   lambda mo: mo.group(0)[0].upper() +\n      ...                              mo.group(0)[1:].lower(),\n      ...                   s)\n      ...\n      >>> titlecase("they\'re bill\'s friends.")\n      "They\'re Bill\'s Friends."\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.translate(table[, deletechars])\n\n   Return a copy of the string where all characters occurring in the\n   optional argument *deletechars* are removed, and the remaining\n   characters have been mapped through the given translation table,\n   which must be a string of length 256.\n\n   You can use the ``maketrans()`` helper function in the ``string``\n   module to create a translation table. For string objects, set the\n   *table* argument to ``None`` for translations that only delete\n   characters:\n\n   >>> \'read this short text\'.translate(None, \'aeiou\')\n   \'rd ths shrt txt\'\n\n   New in version 2.6: Support for a ``None`` *table* argument.\n\n   For Unicode objects, the ``translate()`` method does not accept the\n   optional *deletechars* argument.  Instead, it returns a copy of the\n   *s* where all characters have been mapped through the given\n   translation table which must be a mapping of Unicode ordinals to\n   Unicode ordinals, Unicode strings or ``None``. Unmapped characters\n   are left untouched. Characters mapped to ``None`` are deleted.\n   Note, a more flexible approach is to create a custom character\n   mapping codec using the ``codecs`` module (see ``encodings.cp1251``\n   for an example).\n\nstr.upper()\n\n   Return a copy of the string with all the cased characters [4]\n   converted to uppercase.  Note that ``str.upper().isupper()`` might\n   be ``False`` if ``s`` contains uncased characters or if the Unicode\n   category of the resulting character(s) is not "Lu" (Letter,\n   uppercase), but e.g. "Lt" (Letter, titlecase).\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.zfill(width)\n\n   Return the numeric string left filled with zeros in a string of\n   length *width*.  A sign prefix is handled correctly.  The original\n   string is returned if *width* is less than or equal to ``len(s)``.\n\n   New in version 2.2.2.\n\nThe following methods are present only on unicode objects:\n\nunicode.isnumeric()\n\n   Return ``True`` if there are only numeric characters in S,\n   ``False`` otherwise. Numeric characters include digit characters,\n   and all characters that have the Unicode numeric value property,\n   e.g. U+2155, VULGAR FRACTION ONE FIFTH.\n\nunicode.isdecimal()\n\n   Return ``True`` if there are only decimal characters in S,\n   ``False`` otherwise. Decimal characters include digit characters,\n   and all characters that can be used to form decimal-radix numbers,\n   e.g. U+0660, ARABIC-INDIC DIGIT ZERO.\n',

The backslash (``\\``)\ncharacter is used to escape characters that otherwise have a special\nmeaning, such as newline, backslash itself, or the quote character.\nString literals may optionally be prefixed with a letter ``\'r\'`` or\n``\'R\'``; such strings are called *raw strings* and use different rules\nfor interpreting backslash escape sequences.  A prefix of ``\'u\'`` or\n``\'U\'`` makes the string a Unicode string.  Unicode strings use the\nUnicode character set as defined by the Unicode Consortium and ISO\n10646.  Some additional escape sequences, described below, are\navailable in Unicode strings. A prefix of ``\'b\'`` or ``\'B\'`` is\nignored in Python 2; it indicates that the literal should become a\nbytes literal in Python 3 (e.g. when code is automatically converted\nwith 2to3).  A ``\'u\'`` or ``\'b\'`` prefix may be followed by an ``\'r\'``\nprefix.\n\nIn triple-quoted strings, unescaped newlines and quotes are allowed\n(and are retained), except that three unescaped quotes in a row\nterminate the string.  (A "quote" is the character used to open the\nstring, i.e. either ``\'`` or ``"``.)\n\nUnless an ``\'r\'`` or ``\'R\'`` prefix is present, escape sequences in\nstrings are interpreted according to rules similar to those used by\nStandard C.  The recognized escape sequences are:\n\n+-------------------+-----------------------------------+---------+\n| Escape Sequence   | Meaning                           | Notes   |\n+===================+===================================+=========+\n| ``\\newline``      | Ignored                           |         |\n+-------------------+-----------------------------------+---------+\n| ``\\\\``            | Backslash (``\\``)                 |         |\n+-------------------+-----------------------------------+---------+\n| ``\\\'``            | Single quote (``\'``)              |         |\n+-------------------+-----------------------------------+---------+\n| ``\\"``            | Double quote (``"``)              |         |\n+-------------------+-----------------------------------+---------+\n| ``\\a``            | ASCII Bell (BEL)                  |         |\n+-------------------+-----------------------------------+---------+\n| ``\\b``            | ASCII Backspace (BS)              |         |\n+-------------------+-----------------------------------+---------+\n| ``\\f``            | ASCII Formfeed (FF)               |         |\n+-------------------+-----------------------------------+---------+\n| ``\\n``            | ASCII Linefeed (LF)               |         |\n+-------------------+-----------------------------------+---------+\n| ``\\N{name}``      | Character named *name* in the     |         |\n|                   | Unicode database (Unicode only)   |         |\n+-------------------+-----------------------------------+---------+\n| ``\\r``            | ASCII Carriage Return (CR)        |         |\n+-------------------+-----------------------------------+---------+\n| ``\\t``            | ASCII Horizontal Tab (TAB)        |         |\n+-------------------+-----------------------------------+---------+\n| ``\\uxxxx``        | Character with 16-bit hex value   | (1)     |\n|                   | *xxxx* (Unicode only)             |         |\n+-------------------+-----------------------------------+---------+\n| ``\\Uxxxxxxxx``    | Character with 32-bit hex value   | (2)     |\n|                   | *xxxxxxxx* (Unicode only)         |         |\n+-------------------+-----------------------------------+---------+\n| ``\\v``            | ASCII Vertical Tab (VT)           |         |\n+-------------------+-----------------------------------+---------+\n| ``\\ooo``          | Character with octal value *ooo*  | (3,5)   |\n+-------------------+-----------------------------------+---------+\n| ``\\xhh``          | Character with hex value *hh*     | (4,5)   |\n+-------------------+-----------------------------------+---------+\n\nNotes:\n\n1. Individual code units which form parts of a surrogate pair can be\n   encoded using this escape sequence.\n\n2. Any Unicode character can be encoded this way, but characters\n   outside the Basic Multilingual Plane (BMP) will be encoded using a\n   surrogate pair if Python is compiled to use 16-bit code units (the\n   default).\n\n3. As in Standard C, up to three octal digits are accepted.\n\n4. Unlike in Standard C, exactly two hex digits are required.\n\n5. In a string literal, hexadecimal and octal escapes denote the byte\n   with the given value; it is not necessary that the byte encodes a\n   character in the source character set. In a Unicode literal, these\n   escapes denote a Unicode character with the given value.\n\nUnlike Standard C, all unrecognized escape sequences are left in the\nstring unchanged, i.e., *the backslash is left in the string*.  (This\nbehavior is useful when debugging: if an escape sequence is mistyped,\nthe resulting output is more easily recognized as broken.)  It is also\nimportant to note that the escape sequences marked as "(Unicode only)"\nin the table above fall into the category of unrecognized escapes for\nnon-Unicode string literals.\n\nWhen an ``\'r\'`` or ``\'R\'`` prefix is present, a character following a\nbackslash is included in the string without change, and *all\nbackslashes are left in the string*.  For example, the string literal\n``r"\\n"`` consists of two characters: a backslash and a lowercase\n``\'n\'``.  String quotes can be escaped with a backslash, but the\nbackslash remains in the string; for example, ``r"\\""`` is a valid\nstring literal consisting of two characters: a backslash and a double\nquote; ``r"\\"`` is not a valid string literal (even a raw string\ncannot end in an odd number of backslashes).  Specifically, *a raw\nstring cannot end in a single backslash* (since the backslash would\nescape the following quote character).  Note also that a single\nbackslash followed by a newline is interpreted as those two characters\nas part of the string, *not* as a line continuation.\n\nWhen an ``\'r\'`` or ``\'R\'`` prefix is used in conjunction with a\n``\'u\'`` or ``\'U\'`` prefix, then the ``\\uXXXX`` and ``\\UXXXXXXXX``\nescape sequences are processed while  *all other backslashes are left\nin the string*. For example, the string literal ``ur"\\u0062\\n"``\nconsists of three Unicode characters: \'LATIN SMALL LETTER B\', \'REVERSE\nSOLIDUS\', and \'LATIN SMALL LETTER N\'. Backslashes can be escaped with\na preceding backslash; however, both remain in the string.  As a\nresult, ``\\uXXXX`` escape sequences are only recognized when there are\nan odd number of backslashes.\n',
- 'subscriptions': '\nSubscriptions\n*************\n\nA subscription selects an item of a sequence (string, tuple or list)\nor mapping (dictionary) object:\n\n   subscription ::= primary "[" expression_list "]"\n\nThe primary must evaluate to an object of a sequence or mapping type.\n\nIf the primary is a mapping, the expression list must evaluate to an\nobject whose value is one of the keys of the mapping, and the\nsubscription selects the value in the mapping that corresponds to that\nkey.  (The expression list is a tuple except if it has exactly one\nitem.)\n\nIf the primary is a sequence, the expression (list) must evaluate to a\nplain integer.  If this value is negative, the length of the sequence\nis added to it (so that, e.g., ``x[-1]`` selects the last item of\n``x``.)  The resulting value must be a nonnegative integer less than\nthe number of items in the sequence, and the subscription selects the\nitem whose index is that value (counting from zero).\n\nA string\'s items are characters.  A character is not a separate data\ntype but a string of exactly one character.\n',
- 'truth': "\nTruth Value Testing\n*******************\n\nAny object can be tested for truth value, for use in an ``if`` or\n``while`` condition or as operand of the Boolean operations below. The\nfollowing values are considered false:\n\n* ``None``\n\n* ``False``\n\n* zero of any numeric type, for example, ``0``, ``0L``, ``0.0``,\n  ``0j``.\n\n* any empty sequence, for example, ``''``, ``()``, ``[]``.\n\n* any empty mapping, for example, ``{}``.\n\n* instances of user-defined classes, if the class defines a\n  ``__nonzero__()`` or ``__len__()`` method, when that method returns\n  the integer zero or ``bool`` value ``False``. [1]\n\nAll other values are considered true --- so objects of many types are\nalways true.\n\nOperations and built-in functions that have a Boolean result always\nreturn ``0`` or ``False`` for false and ``1`` or ``True`` for true,\nunless otherwise stated. (Important exception: the Boolean operations\n``or`` and ``and`` always return one of their operands.)\n",
- 'try': '\nThe ``try`` statement\n*********************\n\nThe ``try`` statement specifies exception handlers and/or cleanup code\nfor a group of statements:\n\n   try_stmt  ::= try1_stmt | try2_stmt\n   try1_stmt ::= "try" ":" suite\n                 ("except" [expression [("as" | ",") target]] ":" suite)+\n                 ["else" ":" suite]\n                 ["finally" ":" suite]\n   try2_stmt ::= "try" ":" suite\n                 "finally" ":" suite\n\nChanged in version 2.5: In previous versions of Python,\n``try``...``except``...``finally`` did not work. ``try``...``except``\nhad to be nested in ``try``...``finally``.\n\nThe ``except`` clause(s) specify one or more exception handlers. When\nno exception occurs in the ``try`` clause, no exception handler is\nexecuted. When an exception occurs in the ``try`` suite, a search for\nan exception handler is started.  This search inspects the except\nclauses in turn until one is found that matches the exception.  An\nexpression-less except clause, if present, must be last; it matches\nany exception.  For an except clause with an expression, that\nexpression is evaluated, and the clause matches the exception if the\nresulting object is "compatible" with the exception.  An object is\ncompatible with an exception if it is the class or a base class of the\nexception object, or a tuple containing an item compatible with the\nexception.\n\nIf no except clause matches the exception, the search for an exception\nhandler continues in the surrounding code and on the invocation stack.\n[1]\n\nIf the evaluation of an expression in the header of an except clause\nraises an exception, the original search for a handler is canceled and\na search starts for the new exception in the surrounding code and on\nthe call stack (it is treated as if the entire ``try`` statement\nraised the exception).\n\nWhen a matching except clause is found, the exception is assigned to\nthe target specified in that except clause, if present, and the except\nclause\'s suite is executed.  All except clauses must have an\nexecutable block.  When the end of this block is reached, execution\ncontinues normally after the entire try statement.  (This means that\nif two nested handlers exist for the same exception, and the exception\noccurs in the try clause of the inner handler, the outer handler will\nnot handle the exception.)\n\nBefore an except clause\'s suite is executed, details about the\nexception are assigned to three variables in the ``sys`` module:\n``sys.exc_type`` receives the object identifying the exception;\n``sys.exc_value`` receives the exception\'s parameter;\n``sys.exc_traceback`` receives a traceback object (see section *The\nstandard type hierarchy*) identifying the point in the program where\nthe exception occurred. These details are also available through the\n``sys.exc_info()`` function, which returns a tuple ``(exc_type,\nexc_value, exc_traceback)``.  Use of the corresponding variables is\ndeprecated in favor of this function, since their use is unsafe in a\nthreaded program.  As of Python 1.5, the variables are restored to\ntheir previous values (before the call) when returning from a function\nthat handled an exception.\n\nThe optional ``else`` clause is executed if and when control flows off\nthe end of the ``try`` clause. [2] Exceptions in the ``else`` clause\nare not handled by the preceding ``except`` clauses.\n\nIf ``finally`` is present, it specifies a \'cleanup\' handler.  The\n``try`` clause is executed, including any ``except`` and ``else``\nclauses.  If an exception occurs in any of the clauses and is not\nhandled, the exception is temporarily saved. The ``finally`` clause is\nexecuted.  If there is a saved exception, it is re-raised at the end\nof the ``finally`` clause. If the ``finally`` clause raises another\nexception or executes a ``return`` or ``break`` statement, the saved\nexception is discarded:\n\n   def f():\n       try:\n           1/0\n       finally:\n           return 42\n\n   >>> f()\n   42\n\nThe exception information is not available to the program during\nexecution of the ``finally`` clause.\n\nWhen a ``return``, ``break`` or ``continue`` statement is executed in\nthe ``try`` suite of a ``try``...``finally`` statement, the\n``finally`` clause is also executed \'on the way out.\' A ``continue``\nstatement is illegal in the ``finally`` clause. (The reason is a\nproblem with the current implementation --- this restriction may be\nlifted in the future).\n\nAdditional information on exceptions can be found in section\n*Exceptions*, and information on using the ``raise`` statement to\ngenerate exceptions may be found in section *The raise statement*.\n',
- 'types': '\nThe standard type hierarchy\n***************************\n\nBelow is a list of the types that are built into Python.  Extension\nmodules (written in C, Java, or other languages, depending on the\nimplementation) can define additional types.  Future versions of\nPython may add types to the type hierarchy (e.g., rational numbers,\nefficiently stored arrays of integers, etc.).\n\nSome of the type descriptions below contain a paragraph listing\n\'special attributes.\'  These are attributes that provide access to the\nimplementation and are not intended for general use.  Their definition\nmay change in the future.\n\nNone\n   This type has a single value.  There is a single object with this\n   value. This object is accessed through the built-in name ``None``.\n   It is used to signify the absence of a value in many situations,\n   e.g., it is returned from functions that don\'t explicitly return\n   anything. Its truth value is false.\n\nNotImplemented\n   This type has a single value.  There is a single object with this\n   value. This object is accessed through the built-in name\n   ``NotImplemented``. Numeric methods and rich comparison methods may\n   return this value if they do not implement the operation for the\n   operands provided.  (The interpreter will then try the reflected\n   operation, or some other fallback, depending on the operator.)  Its\n   truth value is true.\n\nEllipsis\n   This type has a single value.  There is a single object with this\n   value. This object is accessed through the built-in name\n   ``Ellipsis``. It is used to indicate the presence of the ``...``\n   syntax in a slice.  Its truth value is true.\n\n``numbers.Number``\n   These are created by numeric literals and returned as results by\n   arithmetic operators and arithmetic built-in functions.  Numeric\n   objects are immutable; once created their value never changes.\n   Python numbers are of course strongly related to mathematical\n   numbers, but subject to the limitations of numerical representation\n   in computers.\n\n   Python distinguishes between integers, floating point numbers, and\n   complex numbers:\n\n   ``numbers.Integral``\n      These represent elements from the mathematical set of integers\n      (positive and negative).\n\n      There are three types of integers:\n\n      Plain integers\n         These represent numbers in the range -2147483648 through\n         2147483647. (The range may be larger on machines with a\n         larger natural word size, but not smaller.)  When the result\n         of an operation would fall outside this range, the result is\n         normally returned as a long integer (in some cases, the\n         exception ``OverflowError`` is raised instead).  For the\n         purpose of shift and mask operations, integers are assumed to\n         have a binary, 2\'s complement notation using 32 or more bits,\n         and hiding no bits from the user (i.e., all 4294967296\n         different bit patterns correspond to different values).\n\n      Long integers\n         These represent numbers in an unlimited range, subject to\n         available (virtual) memory only.  For the purpose of shift\n         and mask operations, a binary representation is assumed, and\n         negative numbers are represented in a variant of 2\'s\n         complement which gives the illusion of an infinite string of\n         sign bits extending to the left.\n\n      Booleans\n         These represent the truth values False and True.  The two\n         objects representing the values False and True are the only\n         Boolean objects. The Boolean type is a subtype of plain\n         integers, and Boolean values behave like the values 0 and 1,\n         respectively, in almost all contexts, the exception being\n         that when converted to a string, the strings ``"False"`` or\n         ``"True"`` are returned, respectively.\n\n      The rules for integer representation are intended to give the\n      most meaningful interpretation of shift and mask operations\n      involving negative integers and the least surprises when\n      switching between the plain and long integer domains.  Any\n      operation, if it yields a result in the plain integer domain,\n      will yield the same result in the long integer domain or when\n      using mixed operands.  The switch between domains is transparent\n      to the programmer.\n\n   ``numbers.Real`` (``float``)\n      These represent machine-level double precision floating point\n      numbers. You are at the mercy of the underlying machine\n      architecture (and C or Java implementation) for the accepted\n      range and handling of overflow. Python does not support single-\n      precision floating point numbers; the savings in processor and\n      memory usage that are usually the reason for using these is\n      dwarfed by the overhead of using objects in Python, so there is\n      no reason to complicate the language with two kinds of floating\n      point numbers.\n\n   ``numbers.Complex``\n      These represent complex numbers as a pair of machine-level\n      double precision floating point numbers.  The same caveats apply\n      as for floating point numbers. The real and imaginary parts of a\n      complex number ``z`` can be retrieved through the read-only\n      attributes ``z.real`` and ``z.imag``.\n\nSequences\n   These represent finite ordered sets indexed by non-negative\n   numbers. The built-in function ``len()`` returns the number of\n   items of a sequence. When the length of a sequence is *n*, the\n   index set contains the numbers 0, 1, ..., *n*-1.  Item *i* of\n   sequence *a* is selected by ``a[i]``.\n\n   Sequences also support slicing: ``a[i:j]`` selects all items with\n   index *k* such that *i* ``<=`` *k* ``<`` *j*.  When used as an\n   expression, a slice is a sequence of the same type.  This implies\n   that the index set is renumbered so that it starts at 0.\n\n   Some sequences also support "extended slicing" with a third "step"\n   parameter: ``a[i:j:k]`` selects all items of *a* with index *x*\n   where ``x = i + n*k``, *n* ``>=`` ``0`` and *i* ``<=`` *x* ``<``\n   *j*.\n\n   Sequences are distinguished according to their mutability:\n\n   Immutable sequences\n      An object of an immutable sequence type cannot change once it is\n      created.  (If the object contains references to other objects,\n      these other objects may be mutable and may be changed; however,\n      the collection of objects directly referenced by an immutable\n      object cannot change.)\n\n      The following types are immutable sequences:\n\n      Strings\n         The items of a string are characters.  There is no separate\n         character type; a character is represented by a string of one\n         item. Characters represent (at least) 8-bit bytes.  The\n         built-in functions ``chr()`` and ``ord()`` convert between\n         characters and nonnegative integers representing the byte\n         values.  Bytes with the values 0-127 usually represent the\n         corresponding ASCII values, but the interpretation of values\n         is up to the program.  The string data type is also used to\n         represent arrays of bytes, e.g., to hold data read from a\n         file.\n\n         (On systems whose native character set is not ASCII, strings\n         may use EBCDIC in their internal representation, provided the\n         functions ``chr()`` and ``ord()`` implement a mapping between\n         ASCII and EBCDIC, and string comparison preserves the ASCII\n         order. Or perhaps someone can propose a better rule?)\n\n      Unicode\n         The items of a Unicode object are Unicode code units.  A\n         Unicode code unit is represented by a Unicode object of one\n         item and can hold either a 16-bit or 32-bit value\n         representing a Unicode ordinal (the maximum value for the\n         ordinal is given in ``sys.maxunicode``, and depends on how\n         Python is configured at compile time).  Surrogate pairs may\n         be present in the Unicode object, and will be reported as two\n         separate items.  The built-in functions ``unichr()`` and\n         ``ord()`` convert between code units and nonnegative integers\n         representing the Unicode ordinals as defined in the Unicode\n         Standard 3.0. Conversion from and to other encodings are\n         possible through the Unicode method ``encode()`` and the\n         built-in function ``unicode()``.\n\n      Tuples\n         The items of a tuple are arbitrary Python objects. Tuples of\n         two or more items are formed by comma-separated lists of\n         expressions.  A tuple of one item (a \'singleton\') can be\n         formed by affixing a comma to an expression (an expression by\n         itself does not create a tuple, since parentheses must be\n         usable for grouping of expressions).  An empty tuple can be\n         formed by an empty pair of parentheses.\n\n   Mutable sequences\n      Mutable sequences can be changed after they are created.  The\n      subscription and slicing notations can be used as the target of\n      assignment and ``del`` (delete) statements.\n\n      There are currently two intrinsic mutable sequence types:\n\n      Lists\n         The items of a list are arbitrary Python objects.  Lists are\n         formed by placing a comma-separated list of expressions in\n         square brackets. (Note that there are no special cases needed\n         to form lists of length 0 or 1.)\n\n      Byte Arrays\n         A bytearray object is a mutable array. They are created by\n         the built-in ``bytearray()`` constructor.  Aside from being\n         mutable (and hence unhashable), byte arrays otherwise provide\n         the same interface and functionality as immutable bytes\n         objects.\n\n      The extension module ``array`` provides an additional example of\n      a mutable sequence type.\n\nSet types\n   These represent unordered, finite sets of unique, immutable\n   objects. As such, they cannot be indexed by any subscript. However,\n   they can be iterated over, and the built-in function ``len()``\n   returns the number of items in a set. Common uses for sets are fast\n   membership testing, removing duplicates from a sequence, and\n   computing mathematical operations such as intersection, union,\n   difference, and symmetric difference.\n\n   For set elements, the same immutability rules apply as for\n   dictionary keys. Note that numeric types obey the normal rules for\n   numeric comparison: if two numbers compare equal (e.g., ``1`` and\n   ``1.0``), only one of them can be contained in a set.\n\n   There are currently two intrinsic set types:\n\n   Sets\n      These represent a mutable set. They are created by the built-in\n      ``set()`` constructor and can be modified afterwards by several\n      methods, such as ``add()``.\n\n   Frozen sets\n      These represent an immutable set.  They are created by the\n      built-in ``frozenset()`` constructor.  As a frozenset is\n      immutable and *hashable*, it can be used again as an element of\n      another set, or as a dictionary key.\n\nMappings\n   These represent finite sets of objects indexed by arbitrary index\n   sets. The subscript notation ``a[k]`` selects the item indexed by\n   ``k`` from the mapping ``a``; this can be used in expressions and\n   as the target of assignments or ``del`` statements. The built-in\n   function ``len()`` returns the number of items in a mapping.\n\n   There is currently a single intrinsic mapping type:\n\n   Dictionaries\n      These represent finite sets of objects indexed by nearly\n      arbitrary values.  The only types of values not acceptable as\n      keys are values containing lists or dictionaries or other\n      mutable types that are compared by value rather than by object\n      identity, the reason being that the efficient implementation of\n      dictionaries requires a key\'s hash value to remain constant.\n      Numeric types used for keys obey the normal rules for numeric\n      comparison: if two numbers compare equal (e.g., ``1`` and\n      ``1.0``) then they can be used interchangeably to index the same\n      dictionary entry.\n\n      Dictionaries are mutable; they can be created by the ``{...}``\n      notation (see section *Dictionary displays*).\n\n      The extension modules ``dbm``, ``gdbm``, and ``bsddb`` provide\n      additional examples of mapping types.\n\nCallable types\n   These are the types to which the function call operation (see\n   section *Calls*) can be applied:\n\n   User-defined functions\n      A user-defined function object is created by a function\n      definition (see section *Function definitions*).  It should be\n      called with an argument list containing the same number of items\n      as the function\'s formal parameter list.\n\n      Special attributes:\n\n      +-------------------------+---------------------------------+-------------+\n      | Attribute               | Meaning                         |             |\n      +=========================+=================================+=============+\n      | ``func_doc``            | The function\'s documentation    | Writable    |\n      |                         | string, or ``None`` if          |             |\n      |                         | unavailable                     |             |\n      +-------------------------+---------------------------------+-------------+\n      | ``__doc__``             | Another way of spelling         | Writable    |\n      |                         | ``func_doc``                    |             |\n      +-------------------------+---------------------------------+-------------+\n      | ``func_name``           | The function\'s name             | Writable    |\n      +-------------------------+---------------------------------+-------------+\n      | ``__name__``            | Another way of spelling         | Writable    |\n      |                         | ``func_name``                   |             |\n      +-------------------------+---------------------------------+-------------+\n      | ``__module__``          | The name of the module the      | Writable    |\n      |                         | function was defined in, or     |             |\n      |                         | ``None`` if unavailable.        |             |\n      +-------------------------+---------------------------------+-------------+\n      | ``func_defaults``       | A tuple containing default      | Writable    |\n      |                         | argument values for those       |             |\n      |                         | arguments that have defaults,   |             |\n      |                         | or ``None`` if no arguments     |             |\n      |                         | have a default value            |             |\n      +-------------------------+---------------------------------+-------------+\n      | ``func_code``           | The code object representing    | Writable    |\n      |                         | the compiled function body.     |             |\n      +-------------------------+---------------------------------+-------------+\n      | ``func_globals``        | A reference to the dictionary   | Read-only   |\n      |                         | that holds the function\'s       |             |\n      |                         | global variables --- the global |             |\n      |                         | namespace of the module in      |             |\n      |                         | which the function was defined. |             |\n      +-------------------------+---------------------------------+-------------+\n      | ``func_dict``           | The namespace supporting        | Writable    |\n      |                         | arbitrary function attributes.  |             |\n      +-------------------------+---------------------------------+-------------+\n      | ``func_closure``        | ``None`` or a tuple of cells    | Read-only   |\n      |                         | that contain bindings for the   |             |\n      |                         | function\'s free variables.      |             |\n      +-------------------------+---------------------------------+-------------+\n\n      Most of the attributes labelled "Writable" check the type of the\n      assigned value.\n\n      Changed in version 2.4: ``func_name`` is now writable.\n\n      Function objects also support getting and setting arbitrary\n      attributes, which can be used, for example, to attach metadata\n      to functions.  Regular attribute dot-notation is used to get and\n      set such attributes. *Note that the current implementation only\n      supports function attributes on user-defined functions. Function\n      attributes on built-in functions may be supported in the\n      future.*\n\n      Additional information about a function\'s definition can be\n      retrieved from its code object; see the description of internal\n      types below.\n\n   User-defined methods\n      A user-defined method object combines a class, a class instance\n      (or ``None``) and any callable object (normally a user-defined\n      function).\n\n      Special read-only attributes: ``im_self`` is the class instance\n      object, ``im_func`` is the function object; ``im_class`` is the\n      class of ``im_self`` for bound methods or the class that asked\n      for the method for unbound methods; ``__doc__`` is the method\'s\n      documentation (same as ``im_func.__doc__``); ``__name__`` is the\n      method name (same as ``im_func.__name__``); ``__module__`` is\n      the name of the module the method was defined in, or ``None`` if\n      unavailable.\n\n      Changed in version 2.2: ``im_self`` used to refer to the class\n      that defined the method.\n\n      Changed in version 2.6: For Python 3 forward-compatibility,\n      ``im_func`` is also available as ``__func__``, and ``im_self``\n      as ``__self__``.\n\n      Methods also support accessing (but not setting) the arbitrary\n      function attributes on the underlying function object.\n\n      User-defined method objects may be created when getting an\n      attribute of a class (perhaps via an instance of that class), if\n      that attribute is a user-defined function object, an unbound\n      user-defined method object, or a class method object. When the\n      attribute is a user-defined method object, a new method object\n      is only created if the class from which it is being retrieved is\n      the same as, or a derived class of, the class stored in the\n      original method object; otherwise, the original method object is\n      used as it is.\n\n      When a user-defined method object is created by retrieving a\n      user-defined function object from a class, its ``im_self``\n      attribute is ``None`` and the method object is said to be\n      unbound. When one is created by retrieving a user-defined\n      function object from a class via one of its instances, its\n      ``im_self`` attribute is the instance, and the method object is\n      said to be bound. In either case, the new method\'s ``im_class``\n      attribute is the class from which the retrieval takes place, and\n      its ``im_func`` attribute is the original function object.\n\n      When a user-defined method object is created by retrieving\n      another method object from a class or instance, the behaviour is\n      the same as for a function object, except that the ``im_func``\n      attribute of the new instance is not the original method object\n      but its ``im_func`` attribute.\n\n      When a user-defined method object is created by retrieving a\n      class method object from a class or instance, its ``im_self``\n      attribute is the class itself, and its ``im_func`` attribute is\n      the function object underlying the class method.\n\n      When an unbound user-defined method object is called, the\n      underlying function (``im_func``) is called, with the\n      restriction that the first argument must be an instance of the\n      proper class (``im_class``) or of a derived class thereof.\n\n      When a bound user-defined method object is called, the\n      underlying function (``im_func``) is called, inserting the class\n      instance (``im_self``) in front of the argument list.  For\n      instance, when ``C`` is a class which contains a definition for\n      a function ``f()``, and ``x`` is an instance of ``C``, calling\n      ``x.f(1)`` is equivalent to calling ``C.f(x, 1)``.\n\n      When a user-defined method object is derived from a class method\n      object, the "class instance" stored in ``im_self`` will actually\n      be the class itself, so that calling either ``x.f(1)`` or\n      ``C.f(1)`` is equivalent to calling ``f(C,1)`` where ``f`` is\n      the underlying function.\n\n      Note that the transformation from function object to (unbound or\n      bound) method object happens each time the attribute is\n      retrieved from the class or instance. In some cases, a fruitful\n      optimization is to assign the attribute to a local variable and\n      call that local variable. Also notice that this transformation\n      only happens for user-defined functions; other callable objects\n      (and all non-callable objects) are retrieved without\n      transformation.  It is also important to note that user-defined\n      functions which are attributes of a class instance are not\n      converted to bound methods; this *only* happens when the\n      function is an attribute of the class.\n\n   Generator functions\n      A function or method which uses the ``yield`` statement (see\n      section *The yield statement*) is called a *generator function*.\n      Such a function, when called, always returns an iterator object\n      which can be used to execute the body of the function:  calling\n      the iterator\'s ``next()`` method will cause the function to\n      execute until it provides a value using the ``yield`` statement.\n      When the function executes a ``return`` statement or falls off\n      the end, a ``StopIteration`` exception is raised and the\n      iterator will have reached the end of the set of values to be\n      returned.\n\n   Built-in functions\n      A built-in function object is a wrapper around a C function.\n      Examples of built-in functions are ``len()`` and ``math.sin()``\n      (``math`` is a standard built-in module). The number and type of\n      the arguments are determined by the C function. Special read-\n      only attributes: ``__doc__`` is the function\'s documentation\n      string, or ``None`` if unavailable; ``__name__`` is the\n      function\'s name; ``__self__`` is set to ``None`` (but see the\n      next item); ``__module__`` is the name of the module the\n      function was defined in or ``None`` if unavailable.\n\n   Built-in methods\n      This is really a different disguise of a built-in function, this\n      time containing an object passed to the C function as an\n      implicit extra argument.  An example of a built-in method is\n      ``alist.append()``, assuming *alist* is a list object. In this\n      case, the special read-only attribute ``__self__`` is set to the\n      object denoted by *alist*.\n\n   Class Types\n      Class types, or "new-style classes," are callable.  These\n      objects normally act as factories for new instances of\n      themselves, but variations are possible for class types that\n      override ``__new__()``.  The arguments of the call are passed to\n      ``__new__()`` and, in the typical case, to ``__init__()`` to\n      initialize the new instance.\n\n   Classic Classes\n      Class objects are described below.  When a class object is\n      called, a new class instance (also described below) is created\n      and returned.  This implies a call to the class\'s ``__init__()``\n      method if it has one.  Any arguments are passed on to the\n      ``__init__()`` method.  If there is no ``__init__()`` method,\n      the class must be called without arguments.\n\n   Class instances\n      Class instances are described below.  Class instances are\n      callable only when the class has a ``__call__()`` method;\n      ``x(arguments)`` is a shorthand for ``x.__call__(arguments)``.\n\nModules\n   Modules are imported by the ``import`` statement (see section *The\n   import statement*). A module object has a namespace implemented by\n   a dictionary object (this is the dictionary referenced by the\n   func_globals attribute of functions defined in the module).\n   Attribute references are translated to lookups in this dictionary,\n   e.g., ``m.x`` is equivalent to ``m.__dict__["x"]``. A module object\n   does not contain the code object used to initialize the module\n   (since it isn\'t needed once the initialization is done).\n\n   Attribute assignment updates the module\'s namespace dictionary,\n   e.g., ``m.x = 1`` is equivalent to ``m.__dict__["x"] = 1``.\n\n   Special read-only attribute: ``__dict__`` is the module\'s namespace\n   as a dictionary object.\n\n   **CPython implementation detail:** Because of the way CPython\n   clears module dictionaries, the module dictionary will be cleared\n   when the module falls out of scope even if the dictionary still has\n   live references.  To avoid this, copy the dictionary or keep the\n   module around while using its dictionary directly.\n\n   Predefined (writable) attributes: ``__name__`` is the module\'s\n   name; ``__doc__`` is the module\'s documentation string, or ``None``\n   if unavailable; ``__file__`` is the pathname of the file from which\n   the module was loaded, if it was loaded from a file. The\n   ``__file__`` attribute is not present for C modules that are\n   statically linked into the interpreter; for extension modules\n   loaded dynamically from a shared library, it is the pathname of the\n   shared library file.\n\nClasses\n   Both class types (new-style classes) and class objects (old-\n   style/classic classes) are typically created by class definitions\n   (see section *Class definitions*).  A class has a namespace\n   implemented by a dictionary object. Class attribute references are\n   translated to lookups in this dictionary, e.g., ``C.x`` is\n   translated to ``C.__dict__["x"]`` (although for new-style classes\n   in particular there are a number of hooks which allow for other\n   means of locating attributes). When the attribute name is not found\n   there, the attribute search continues in the base classes.  For\n   old-style classes, the search is depth-first, left-to-right in the\n   order of occurrence in the base class list. New-style classes use\n   the more complex C3 method resolution order which behaves correctly\n   even in the presence of \'diamond\' inheritance structures where\n   there are multiple inheritance paths leading back to a common\n   ancestor. Additional details on the C3 MRO used by new-style\n   classes can be found in the documentation accompanying the 2.3\n   release at http://www.python.org/download/releases/2.3/mro/.\n\n   When a class attribute reference (for class ``C``, say) would yield\n   a user-defined function object or an unbound user-defined method\n   object whose associated class is either ``C`` or one of its base\n   classes, it is transformed into an unbound user-defined method\n   object whose ``im_class`` attribute is ``C``. When it would yield a\n   class method object, it is transformed into a bound user-defined\n   method object whose ``im_self`` attribute is ``C``.  When it would\n   yield a static method object, it is transformed into the object\n   wrapped by the static method object. See section *Implementing\n   Descriptors* for another way in which attributes retrieved from a\n   class may differ from those actually contained in its ``__dict__``\n   (note that only new-style classes support descriptors).\n\n   Class attribute assignments update the class\'s dictionary, never\n   the dictionary of a base class.\n\n   A class object can be called (see above) to yield a class instance\n   (see below).\n\n   Special attributes: ``__name__`` is the class name; ``__module__``\n   is the module name in which the class was defined; ``__dict__`` is\n   the dictionary containing the class\'s namespace; ``__bases__`` is a\n   tuple (possibly empty or a singleton) containing the base classes,\n   in the order of their occurrence in the base class list;\n   ``__doc__`` is the class\'s documentation string, or None if\n   undefined.\n\nClass instances\n   A class instance is created by calling a class object (see above).\n   A class instance has a namespace implemented as a dictionary which\n   is the first place in which attribute references are searched.\n   When an attribute is not found there, and the instance\'s class has\n   an attribute by that name, the search continues with the class\n   attributes.  If a class attribute is found that is a user-defined\n   function object or an unbound user-defined method object whose\n   associated class is the class (call it ``C``) of the instance for\n   which the attribute reference was initiated or one of its bases, it\n   is transformed into a bound user-defined method object whose\n   ``im_class`` attribute is ``C`` and whose ``im_self`` attribute is\n   the instance. Static method and class method objects are also\n   transformed, as if they had been retrieved from class ``C``; see\n   above under "Classes". See section *Implementing Descriptors* for\n   another way in which attributes of a class retrieved via its\n   instances may differ from the objects actually stored in the\n   class\'s ``__dict__``. If no class attribute is found, and the\n   object\'s class has a ``__getattr__()`` method, that is called to\n   satisfy the lookup.\n\n   Attribute assignments and deletions update the instance\'s\n   dictionary, never a class\'s dictionary.  If the class has a\n   ``__setattr__()`` or ``__delattr__()`` method, this is called\n   instead of updating the instance dictionary directly.\n\n   Class instances can pretend to be numbers, sequences, or mappings\n   if they have methods with certain special names.  See section\n   *Special method names*.\n\n   Special attributes: ``__dict__`` is the attribute dictionary;\n   ``__class__`` is the instance\'s class.\n\nFiles\n   A file object represents an open file.  File objects are created by\n   the ``open()`` built-in function, and also by ``os.popen()``,\n   ``os.fdopen()``, and the ``makefile()`` method of socket objects\n   (and perhaps by other functions or methods provided by extension\n   modules).  The objects ``sys.stdin``, ``sys.stdout`` and\n   ``sys.stderr`` are initialized to file objects corresponding to the\n   interpreter\'s standard input, output and error streams.  See *File\n   Objects* for complete documentation of file objects.\n\nInternal types\n   A few types used internally by the interpreter are exposed to the\n   user. Their definitions may change with future versions of the\n   interpreter, but they are mentioned here for completeness.\n\n   Code objects\n      Code objects represent *byte-compiled* executable Python code,\n      or *bytecode*. The difference between a code object and a\n      function object is that the function object contains an explicit\n      reference to the function\'s globals (the module in which it was\n      defined), while a code object contains no context; also the\n      default argument values are stored in the function object, not\n      in the code object (because they represent values calculated at\n      run-time).  Unlike function objects, code objects are immutable\n      and contain no references (directly or indirectly) to mutable\n      objects.\n\n      Special read-only attributes: ``co_name`` gives the function\n      name; ``co_argcount`` is the number of positional arguments\n      (including arguments with default values); ``co_nlocals`` is the\n      number of local variables used by the function (including\n      arguments); ``co_varnames`` is a tuple containing the names of\n      the local variables (starting with the argument names);\n      ``co_cellvars`` is a tuple containing the names of local\n      variables that are referenced by nested functions;\n      ``co_freevars`` is a tuple containing the names of free\n      variables; ``co_code`` is a string representing the sequence of\n      bytecode instructions; ``co_consts`` is a tuple containing the\n      literals used by the bytecode; ``co_names`` is a tuple\n      containing the names used by the bytecode; ``co_filename`` is\n      the filename from which the code was compiled;\n      ``co_firstlineno`` is the first line number of the function;\n      ``co_lnotab`` is a string encoding the mapping from bytecode\n      offsets to line numbers (for details see the source code of the\n      interpreter); ``co_stacksize`` is the required stack size\n      (including local variables); ``co_flags`` is an integer encoding\n      a number of flags for the interpreter.\n\n      The following flag bits are defined for ``co_flags``: bit\n      ``0x04`` is set if the function uses the ``*arguments`` syntax\n      to accept an arbitrary number of positional arguments; bit\n      ``0x08`` is set if the function uses the ``**keywords`` syntax\n      to accept arbitrary keyword arguments; bit ``0x20`` is set if\n      the function is a generator.\n\n      Future feature declarations (``from __future__ import\n      division``) also use bits in ``co_flags`` to indicate whether a\n      code object was compiled with a particular feature enabled: bit\n      ``0x2000`` is set if the function was compiled with future\n      division enabled; bits ``0x10`` and ``0x1000`` were used in\n      earlier versions of Python.\n\n      Other bits in ``co_flags`` are reserved for internal use.\n\n      If a code object represents a function, the first item in\n      ``co_consts`` is the documentation string of the function, or\n      ``None`` if undefined.\n\n   Frame objects\n      Frame objects represent execution frames.  They may occur in\n      traceback objects (see below).\n\n      Special read-only attributes: ``f_back`` is to the previous\n      stack frame (towards the caller), or ``None`` if this is the\n      bottom stack frame; ``f_code`` is the code object being executed\n      in this frame; ``f_locals`` is the dictionary used to look up\n      local variables; ``f_globals`` is used for global variables;\n      ``f_builtins`` is used for built-in (intrinsic) names;\n      ``f_restricted`` is a flag indicating whether the function is\n      executing in restricted execution mode; ``f_lasti`` gives the\n      precise instruction (this is an index into the bytecode string\n      of the code object).\n\n      Special writable attributes: ``f_trace``, if not ``None``, is a\n      function called at the start of each source code line (this is\n      used by the debugger); ``f_exc_type``, ``f_exc_value``,\n      ``f_exc_traceback`` represent the last exception raised in the\n      parent frame provided another exception was ever raised in the\n      current frame (in all other cases they are None); ``f_lineno``\n      is the current line number of the frame --- writing to this from\n      within a trace function jumps to the given line (only for the\n      bottom-most frame).  A debugger can implement a Jump command\n      (aka Set Next Statement) by writing to f_lineno.\n\n   Traceback objects\n      Traceback objects represent a stack trace of an exception.  A\n      traceback object is created when an exception occurs.  When the\n      search for an exception handler unwinds the execution stack, at\n      each unwound level a traceback object is inserted in front of\n      the current traceback.  When an exception handler is entered,\n      the stack trace is made available to the program. (See section\n      *The try statement*.) It is accessible as ``sys.exc_traceback``,\n      and also as the third item of the tuple returned by\n      ``sys.exc_info()``.  The latter is the preferred interface,\n      since it works correctly when the program is using multiple\n      threads. When the program contains no suitable handler, the\n      stack trace is written (nicely formatted) to the standard error\n      stream; if the interpreter is interactive, it is also made\n      available to the user as ``sys.last_traceback``.\n\n      Special read-only attributes: ``tb_next`` is the next level in\n      the stack trace (towards the frame where the exception\n      occurred), or ``None`` if there is no next level; ``tb_frame``\n      points to the execution frame of the current level;\n      ``tb_lineno`` gives the line number where the exception\n      occurred; ``tb_lasti`` indicates the precise instruction.  The\n      line number and last instruction in the traceback may differ\n      from the line number of its frame object if the exception\n      occurred in a ``try`` statement with no matching except clause\n      or with a finally clause.\n\n   Slice objects\n      Slice objects are used to represent slices when *extended slice\n      syntax* is used. This is a slice using two colons, or multiple\n      slices or ellipses separated by commas, e.g., ``a[i:j:step]``,\n      ``a[i:j, k:l]``, or ``a[..., i:j]``.  They are also created by\n      the built-in ``slice()`` function.\n\n      Special read-only attributes: ``start`` is the lower bound;\n      ``stop`` is the upper bound; ``step`` is the step value; each is\n      ``None`` if omitted.  These attributes can have any type.\n\n      Slice objects support one method:\n\n      slice.indices(self, length)\n\n         This method takes a single integer argument *length* and\n         computes information about the extended slice that the slice\n         object would describe if applied to a sequence of *length*\n         items.  It returns a tuple of three integers; respectively\n         these are the *start* and *stop* indices and the *step* or\n         stride length of the slice. Missing or out-of-bounds indices\n         are handled in a manner consistent with regular slices.\n\n         New in version 2.3.\n\n   Static method objects\n      Static method objects provide a way of defeating the\n      transformation of function objects to method objects described\n      above. A static method object is a wrapper around any other\n      object, usually a user-defined method object. When a static\n      method object is retrieved from a class or a class instance, the\n      object actually returned is the wrapped object, which is not\n      subject to any further transformation. Static method objects are\n      not themselves callable, although the objects they wrap usually\n      are. Static method objects are created by the built-in\n      ``staticmethod()`` constructor.\n\n   Class method objects\n      A class method object, like a static method object, is a wrapper\n      around another object that alters the way in which that object\n      is retrieved from classes and class instances. The behaviour of\n      class method objects upon such retrieval is described above,\n      under "User-defined methods". Class method objects are created\n      by the built-in ``classmethod()`` constructor.\n',
- 'typesfunctions': '\nFunctions\n*********\n\nFunction objects are created by function definitions.  The only\noperation on a function object is to call it: ``func(argument-list)``.\n\nThere are really two flavors of function objects: built-in functions\nand user-defined functions.  Both support the same operation (to call\nthe function), but the implementation is different, hence the\ndifferent object types.\n\nSee *Function definitions* for more information.\n',
- 'typesmapping': '\nMapping Types --- ``dict``\n**************************\n\nA *mapping* object maps *hashable* values to arbitrary objects.\nMappings are mutable objects.  There is currently only one standard\nmapping type, the *dictionary*.  (For other containers see the built\nin ``list``, ``set``, and ``tuple`` classes, and the ``collections``\nmodule.)\n\nA dictionary\'s keys are *almost* arbitrary values.  Values that are\nnot *hashable*, that is, values containing lists, dictionaries or\nother mutable types (that are compared by value rather than by object\nidentity) may not be used as keys.  Numeric types used for keys obey\nthe normal rules for numeric comparison: if two numbers compare equal\n(such as ``1`` and ``1.0``) then they can be used interchangeably to\nindex the same dictionary entry.  (Note however, that since computers\nstore floating-point numbers as approximations it is usually unwise to\nuse them as dictionary keys.)\n\nDictionaries can be created by placing a comma-separated list of\n``key: value`` pairs within braces, for example: ``{\'jack\': 4098,\n\'sjoerd\': 4127}`` or ``{4098: \'jack\', 4127: \'sjoerd\'}``, or by the\n``dict`` constructor.\n\nclass class dict(**kwarg)\nclass class dict(mapping, **kwarg)\nclass class dict(iterable, **kwarg)\n\n   Return a new dictionary initialized from an optional positional\n   argument and a possibly empty set of keyword arguments.\n\n   If no positional argument is given, an empty dictionary is created.\n   If a positional argument is given and it is a mapping object, a\n   dictionary is created with the same key-value pairs as the mapping\n   object.  Otherwise, the positional argument must be an *iterator*\n   object.  Each item in the iterable must itself be an iterator with\n   exactly two objects.  The first object of each item becomes a key\n   in the new dictionary, and the second object the corresponding\n   value.  If a key occurs more than once, the last value for that key\n   becomes the corresponding value in the new dictionary.\n\n   If keyword arguments are given, the keyword arguments and their\n   values are added to the dictionary created from the positional\n   argument.  If a key being added is already present, the value from\n   the keyword argument replaces the value from the positional\n   argument.\n\n   To illustrate, the following examples all return a dictionary equal\n   to ``{"one": 1, "two": 2, "three": 3}``:\n\n      >>> a = dict(one=1, two=2, three=3)\n      >>> b = {\'one\': 1, \'two\': 2, \'three\': 3}\n      >>> c = dict(zip([\'one\', \'two\', \'three\'], [1, 2, 3]))\n      >>> d = dict([(\'two\', 2), (\'one\', 1), (\'three\', 3)])\n      >>> e = dict({\'three\': 3, \'one\': 1, \'two\': 2})\n      >>> a == b == c == d == e\n      True\n\n   Providing keyword arguments as in the first example only works for\n   keys that are valid Python identifiers.  Otherwise, any valid keys\n   can be used.\n\n   New in version 2.2.\n\n   Changed in version 2.3: Support for building a dictionary from\n   keyword arguments added.\n\n   These are the operations that dictionaries support (and therefore,\n   custom mapping types should support too):\n\n   len(d)\n\n      Return the number of items in the dictionary *d*.\n\n   d[key]\n\n      Return the item of *d* with key *key*.  Raises a ``KeyError`` if\n      *key* is not in the map.\n\n      New in version 2.5: If a subclass of dict defines a method\n      ``__missing__()``, if the key *key* is not present, the\n      ``d[key]`` operation calls that method with the key *key* as\n      argument.  The ``d[key]`` operation then returns or raises\n      whatever is returned or raised by the ``__missing__(key)`` call\n      if the key is not present. No other operations or methods invoke\n      ``__missing__()``. If ``__missing__()`` is not defined,\n      ``KeyError`` is raised.  ``__missing__()`` must be a method; it\n      cannot be an instance variable. For an example, see\n      ``collections.defaultdict``.\n\n   d[key] = value\n\n      Set ``d[key]`` to *value*.\n\n   del d[key]\n\n      Remove ``d[key]`` from *d*.  Raises a ``KeyError`` if *key* is\n      not in the map.\n\n   key in d\n\n      Return ``True`` if *d* has a key *key*, else ``False``.\n\n      New in version 2.2.\n\n   key not in d\n\n      Equivalent to ``not key in d``.\n\n      New in version 2.2.\n\n   iter(d)\n\n      Return an iterator over the keys of the dictionary.  This is a\n      shortcut for ``iterkeys()``.\n\n   clear()\n\n      Remove all items from the dictionary.\n\n   copy()\n\n      Return a shallow copy of the dictionary.\n\n   fromkeys(seq[, value])\n\n      Create a new dictionary with keys from *seq* and values set to\n      *value*.\n\n      ``fromkeys()`` is a class method that returns a new dictionary.\n      *value* defaults to ``None``.\n\n      New in version 2.3.\n\n   get(key[, default])\n\n      Return the value for *key* if *key* is in the dictionary, else\n      *default*. If *default* is not given, it defaults to ``None``,\n      so that this method never raises a ``KeyError``.\n\n   has_key(key)\n\n      Test for the presence of *key* in the dictionary.  ``has_key()``\n      is deprecated in favor of ``key in d``.\n\n   items()\n\n      Return a copy of the dictionary\'s list of ``(key, value)``\n      pairs.\n\n      **CPython implementation detail:** Keys and values are listed in\n      an arbitrary order which is non-random, varies across Python\n      implementations, and depends on the dictionary\'s history of\n      insertions and deletions.\n\n      If ``items()``, ``keys()``, ``values()``, ``iteritems()``,\n      ``iterkeys()``, and ``itervalues()`` are called with no\n      intervening modifications to the dictionary, the lists will\n      directly correspond.  This allows the creation of ``(value,\n      key)`` pairs using ``zip()``: ``pairs = zip(d.values(),\n      d.keys())``.  The same relationship holds for the ``iterkeys()``\n      and ``itervalues()`` methods: ``pairs = zip(d.itervalues(),\n      d.iterkeys())`` provides the same value for ``pairs``. Another\n      way to create the same list is ``pairs = [(v, k) for (k, v) in\n      d.iteritems()]``.\n\n   iteritems()\n\n      Return an iterator over the dictionary\'s ``(key, value)`` pairs.\n      See the note for ``dict.items()``.\n\n      Using ``iteritems()`` while adding or deleting entries in the\n      dictionary may raise a ``RuntimeError`` or fail to iterate over\n      all entries.\n\n      New in version 2.2.\n\n   iterkeys()\n\n      Return an iterator over the dictionary\'s keys.  See the note for\n      ``dict.items()``.\n\n      Using ``iterkeys()`` while adding or deleting entries in the\n      dictionary may raise a ``RuntimeError`` or fail to iterate over\n      all entries.\n\n      New in version 2.2.\n\n   itervalues()\n\n      Return an iterator over the dictionary\'s values.  See the note\n      for ``dict.items()``.\n\n      Using ``itervalues()`` while adding or deleting entries in the\n      dictionary may raise a ``RuntimeError`` or fail to iterate over\n      all entries.\n\n      New in version 2.2.\n\n   keys()\n\n      Return a copy of the dictionary\'s list of keys.  See the note\n      for ``dict.items()``.\n\n   pop(key[, default])\n\n      If *key* is in the dictionary, remove it and return its value,\n      else return *default*.  If *default* is not given and *key* is\n      not in the dictionary, a ``KeyError`` is raised.\n\n      New in version 2.3.\n\n   popitem()\n\n      Remove and return an arbitrary ``(key, value)`` pair from the\n      dictionary.\n\n      ``popitem()`` is useful to destructively iterate over a\n      dictionary, as often used in set algorithms.  If the dictionary\n      is empty, calling ``popitem()`` raises a ``KeyError``.\n\n   setdefault(key[, default])\n\n      If *key* is in the dictionary, return its value.  If not, insert\n      *key* with a value of *default* and return *default*.  *default*\n      defaults to ``None``.\n\n   update([other])\n\n      Update the dictionary with the key/value pairs from *other*,\n      overwriting existing keys.  Return ``None``.\n\n      ``update()`` accepts either another dictionary object or an\n      iterable of key/value pairs (as tuples or other iterables of\n      length two).  If keyword arguments are specified, the dictionary\n      is then updated with those key/value pairs: ``d.update(red=1,\n      blue=2)``.\n\n      Changed in version 2.4: Allowed the argument to be an iterable\n      of key/value pairs and allowed keyword arguments.\n\n   values()\n\n      Return a copy of the dictionary\'s list of values.  See the note\n      for ``dict.items()``.\n\n   viewitems()\n\n      Return a new view of the dictionary\'s items (``(key, value)``\n      pairs).  See below for documentation of view objects.\n\n      New in version 2.7.\n\n   viewkeys()\n\n      Return a new view of the dictionary\'s keys.  See below for\n      documentation of view objects.\n\n      New in version 2.7.\n\n   viewvalues()\n\n      Return a new view of the dictionary\'s values.  See below for\n      documentation of view objects.\n\n      New in version 2.7.\n\n\nDictionary view objects\n=======================\n\nThe objects returned by ``dict.viewkeys()``, ``dict.viewvalues()`` and\n``dict.viewitems()`` are *view objects*.  They provide a dynamic view\non the dictionary\'s entries, which means that when the dictionary\nchanges, the view reflects these changes.\n\nDictionary views can be iterated over to yield their respective data,\nand support membership tests:\n\nlen(dictview)\n\n   Return the number of entries in the dictionary.\n\niter(dictview)\n\n   Return an iterator over the keys, values or items (represented as\n   tuples of ``(key, value)``) in the dictionary.\n\n   Keys and values are iterated over in an arbitrary order which is\n   non-random, varies across Python implementations, and depends on\n   the dictionary\'s history of insertions and deletions. If keys,\n   values and items views are iterated over with no intervening\n   modifications to the dictionary, the order of items will directly\n   correspond.  This allows the creation of ``(value, key)`` pairs\n   using ``zip()``: ``pairs = zip(d.values(), d.keys())``.  Another\n   way to create the same list is ``pairs = [(v, k) for (k, v) in\n   d.items()]``.\n\n   Iterating views while adding or deleting entries in the dictionary\n   may raise a ``RuntimeError`` or fail to iterate over all entries.\n\nx in dictview\n\n   Return ``True`` if *x* is in the underlying dictionary\'s keys,\n   values or items (in the latter case, *x* should be a ``(key,\n   value)`` tuple).\n\nKeys views are set-like since their entries are unique and hashable.\nIf all values are hashable, so that (key, value) pairs are unique and\nhashable, then the items view is also set-like.  (Values views are not\ntreated as set-like since the entries are generally not unique.)  Then\nthese set operations are available ("other" refers either to another\nview or a set):\n\ndictview & other\n\n   Return the intersection of the dictview and the other object as a\n   new set.\n\ndictview | other\n\n   Return the union of the dictview and the other object as a new set.\n\ndictview - other\n\n   Return the difference between the dictview and the other object\n   (all elements in *dictview* that aren\'t in *other*) as a new set.\n\ndictview ^ other\n\n   Return the symmetric difference (all elements either in *dictview*\n   or *other*, but not in both) of the dictview and the other object\n   as a new set.\n\nAn example of dictionary view usage:\n\n   >>> dishes = {\'eggs\': 2, \'sausage\': 1, \'bacon\': 1, \'spam\': 500}\n   >>> keys = dishes.viewkeys()\n   >>> values = dishes.viewvalues()\n\n   >>> # iteration\n   >>> n = 0\n   >>> for val in values:\n   ...     n += val\n   >>> print(n)\n   504\n\n   >>> # keys and values are iterated over in the same order\n   >>> list(keys)\n   [\'eggs\', \'bacon\', \'sausage\', \'spam\']\n   >>> list(values)\n   [2, 1, 1, 500]\n\n   >>> # view objects are dynamic and reflect dict changes\n   >>> del dishes[\'eggs\']\n   >>> del dishes[\'sausage\']\n   >>> list(keys)\n   [\'spam\', \'bacon\']\n\n   >>> # set operations\n   >>> keys & {\'eggs\', \'bacon\', \'salad\'}\n   {\'bacon\'}\n',
- 'typesmethods': '\nMethods\n*******\n\nMethods are functions that are called using the attribute notation.\nThere are two flavors: built-in methods (such as ``append()`` on\nlists) and class instance methods.  Built-in methods are described\nwith the types that support them.\n\nThe implementation adds two special read-only attributes to class\ninstance methods: ``m.im_self`` is the object on which the method\noperates, and ``m.im_func`` is the function implementing the method.\nCalling ``m(arg-1, arg-2, ..., arg-n)`` is completely equivalent to\ncalling ``m.im_func(m.im_self, arg-1, arg-2, ..., arg-n)``.\n\nClass instance methods are either *bound* or *unbound*, referring to\nwhether the method was accessed through an instance or a class,\nrespectively.  When a method is unbound, its ``im_self`` attribute\nwill be ``None`` and if called, an explicit ``self`` object must be\npassed as the first argument.  In this case, ``self`` must be an\ninstance of the unbound method\'s class (or a subclass of that class),\notherwise a ``TypeError`` is raised.\n\nLike function objects, methods objects support getting arbitrary\nattributes. However, since method attributes are actually stored on\nthe underlying function object (``meth.im_func``), setting method\nattributes on either bound or unbound methods is disallowed.\nAttempting to set an attribute on a method results in an\n``AttributeError`` being raised.  In order to set a method attribute,\nyou need to explicitly set it on the underlying function object:\n\n   >>> class C:\n   ...     def method(self):\n   ...         pass\n   ...\n   >>> c = C()\n   >>> c.method.whoami = \'my name is method\'  # can\'t set on the method\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in <module>\n   AttributeError: \'instancemethod\' object has no attribute \'whoami\'\n   >>> c.method.im_func.whoami = \'my name is method\'\n   >>> c.method.whoami\n   \'my name is method\'\n\nSee *The standard type hierarchy* for more information.\n',
- 'typesmodules': "\nModules\n*******\n\nThe only special operation on a module is attribute access:\n``m.name``, where *m* is a module and *name* accesses a name defined\nin *m*'s symbol table. Module attributes can be assigned to.  (Note\nthat the ``import`` statement is not, strictly speaking, an operation\non a module object; ``import foo`` does not require a module object\nnamed *foo* to exist, rather it requires an (external) *definition*\nfor a module named *foo* somewhere.)\n\nA special attribute of every module is ``__dict__``. This is the\ndictionary containing the module's symbol table. Modifying this\ndictionary will actually change the module's symbol table, but direct\nassignment to the ``__dict__`` attribute is not possible (you can\nwrite ``m.__dict__['a'] = 1``, which defines ``m.a`` to be ``1``, but\nyou can't write ``m.__dict__ = {}``).  Modifying ``__dict__`` directly\nis not recommended.\n\nModules built into the interpreter are written like this: ``<module\n'sys' (built-in)>``.  If loaded from a file, they are written as\n``<module 'os' from '/usr/local/lib/pythonX.Y/os.pyc'>``.\n",
- 'typesseq': '\nSequence Types --- ``str``, ``unicode``, ``list``, ``tuple``, ``bytearray``, ``buffer``, ``xrange``\n***************************************************************************************************\n\nThere are seven sequence types: strings, Unicode strings, lists,\ntuples, bytearrays, buffers, and xrange objects.\n\nFor other containers see the built in ``dict`` and ``set`` classes,\nand the ``collections`` module.\n\nString literals are written in single or double quotes: ``\'xyzzy\'``,\n``"frobozz"``.  See *String literals* for more about string literals.\nUnicode strings are much like strings, but are specified in the syntax\nusing a preceding ``\'u\'`` character: ``u\'abc\'``, ``u"def"``. In\naddition to the functionality described here, there are also string-\nspecific methods described in the *String Methods* section. Lists are\nconstructed with square brackets, separating items with commas: ``[a,\nb, c]``. Tuples are constructed by the comma operator (not within\nsquare brackets), with or without enclosing parentheses, but an empty\ntuple must have the enclosing parentheses, such as ``a, b, c`` or\n``()``.  A single item tuple must have a trailing comma, such as\n``(d,)``.\n\nBytearray objects are created with the built-in function\n``bytearray()``.\n\nBuffer objects are not directly supported by Python syntax, but can be\ncreated by calling the built-in function ``buffer()``.  They don\'t\nsupport concatenation or repetition.\n\nObjects of type xrange are similar to buffers in that there is no\nspecific syntax to create them, but they are created using the\n``xrange()`` function.  They don\'t support slicing, concatenation or\nrepetition, and using ``in``, ``not in``, ``min()`` or ``max()`` on\nthem is inefficient.\n\nMost sequence types support the following operations.  The ``in`` and\n``not in`` operations have the same priorities as the comparison\noperations.  The ``+`` and ``*`` operations have the same priority as\nthe corresponding numeric operations. [3] Additional methods are\nprovided for *Mutable Sequence Types*.\n\nThis table lists the sequence operations sorted in ascending priority\n(operations in the same box have the same priority).  In the table,\n*s* and *t* are sequences of the same type; *n*, *i* and *j* are\nintegers:\n\n+--------------------+----------------------------------+------------+\n| Operation          | Result                           | Notes      |\n+====================+==================================+============+\n| ``x in s``         | ``True`` if an item of *s* is    | (1)        |\n|                    | equal to *x*, else ``False``     |            |\n+--------------------+----------------------------------+------------+\n| ``x not in s``     | ``False`` if an item of *s* is   | (1)        |\n|                    | equal to *x*, else ``True``      |            |\n+--------------------+----------------------------------+------------+\n| ``s + t``          | the concatenation of *s* and *t* | (6)        |\n+--------------------+----------------------------------+------------+\n| ``s * n, n * s``   | *n* shallow copies of *s*        | (2)        |\n|                    | concatenated                     |            |\n+--------------------+----------------------------------+------------+\n| ``s[i]``           | *i*th item of *s*, origin 0      | (3)        |\n+--------------------+----------------------------------+------------+\n| ``s[i:j]``         | slice of *s* from *i* to *j*     | (3)(4)     |\n+--------------------+----------------------------------+------------+\n| ``s[i:j:k]``       | slice of *s* from *i* to *j*     | (3)(5)     |\n|                    | with step *k*                    |            |\n+--------------------+----------------------------------+------------+\n| ``len(s)``         | length of *s*                    |            |\n+--------------------+----------------------------------+------------+\n| ``min(s)``         | smallest item of *s*             |            |\n+--------------------+----------------------------------+------------+\n| ``max(s)``         | largest item of *s*              |            |\n+--------------------+----------------------------------+------------+\n| ``s.index(i)``     | index of the first occurrence of |            |\n|                    | *i* in *s*                       |            |\n+--------------------+----------------------------------+------------+\n| ``s.count(i)``     | total number of occurrences of   |            |\n|                    | *i* in *s*                       |            |\n+--------------------+----------------------------------+------------+\n\nSequence types also support comparisons. In particular, tuples and\nlists are compared lexicographically by comparing corresponding\nelements. This means that to compare equal, every element must compare\nequal and the two sequences must be of the same type and have the same\nlength. (For full details see *Comparisons* in the language\nreference.)\n\nNotes:\n\n1. When *s* is a string or Unicode string object the ``in`` and ``not\n   in`` operations act like a substring test.  In Python versions\n   before 2.3, *x* had to be a string of length 1. In Python 2.3 and\n   beyond, *x* may be a string of any length.\n\n2. Values of *n* less than ``0`` are treated as ``0`` (which yields an\n   empty sequence of the same type as *s*).  Note also that the copies\n   are shallow; nested structures are not copied.  This often haunts\n   new Python programmers; consider:\n\n   >>> lists = [[]] * 3\n   >>> lists\n   [[], [], []]\n   >>> lists[0].append(3)\n   >>> lists\n   [[3], [3], [3]]\n\n   What has happened is that ``[[]]`` is a one-element list containing\n   an empty list, so all three elements of ``[[]] * 3`` are (pointers\n   to) this single empty list.  Modifying any of the elements of\n   ``lists`` modifies this single list. You can create a list of\n   different lists this way:\n\n   >>> lists = [[] for i in range(3)]\n   >>> lists[0].append(3)\n   >>> lists[1].append(5)\n   >>> lists[2].append(7)\n   >>> lists\n   [[3], [5], [7]]\n\n3. If *i* or *j* is negative, the index is relative to the end of the\n   string: ``len(s) + i`` or ``len(s) + j`` is substituted.  But note\n   that ``-0`` is still ``0``.\n\n4. The slice of *s* from *i* to *j* is defined as the sequence of\n   items with index *k* such that ``i <= k < j``.  If *i* or *j* is\n   greater than ``len(s)``, use ``len(s)``.  If *i* is omitted or\n   ``None``, use ``0``.  If *j* is omitted or ``None``, use\n   ``len(s)``.  If *i* is greater than or equal to *j*, the slice is\n   empty.\n\n5. The slice of *s* from *i* to *j* with step *k* is defined as the\n   sequence of items with index  ``x = i + n*k`` such that ``0 <= n <\n   (j-i)/k``.  In other words, the indices are ``i``, ``i+k``,\n   ``i+2*k``, ``i+3*k`` and so on, stopping when *j* is reached (but\n   never including *j*).  If *i* or *j* is greater than ``len(s)``,\n   use ``len(s)``.  If *i* or *j* are omitted or ``None``, they become\n   "end" values (which end depends on the sign of *k*).  Note, *k*\n   cannot be zero. If *k* is ``None``, it is treated like ``1``.\n\n6. **CPython implementation detail:** If *s* and *t* are both strings,\n   some Python implementations such as CPython can usually perform an\n   in-place optimization for assignments of the form ``s = s + t`` or\n   ``s += t``.  When applicable, this optimization makes quadratic\n   run-time much less likely.  This optimization is both version and\n   implementation dependent.  For performance sensitive code, it is\n   preferable to use the ``str.join()`` method which assures\n   consistent linear concatenation performance across versions and\n   implementations.\n\n   Changed in version 2.4: Formerly, string concatenation never\n   occurred in-place.\n\n\nString Methods\n==============\n\nBelow are listed the string methods which both 8-bit strings and\nUnicode objects support.  Some of them are also available on\n``bytearray`` objects.\n\nIn addition, Python\'s strings support the sequence type methods\ndescribed in the *Sequence Types --- str, unicode, list, tuple,\nbytearray, buffer, xrange* section. To output formatted strings use\ntemplate strings or the ``%`` operator described in the *String\nFormatting Operations* section. Also, see the ``re`` module for string\nfunctions based on regular expressions.\n\nstr.capitalize()\n\n   Return a copy of the string with its first character capitalized\n   and the rest lowercased.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.center(width[, fillchar])\n\n   Return centered in a string of length *width*. Padding is done\n   using the specified *fillchar* (default is a space).\n\n   Changed in version 2.4: Support for the *fillchar* argument.\n\nstr.count(sub[, start[, end]])\n\n   Return the number of non-overlapping occurrences of substring *sub*\n   in the range [*start*, *end*].  Optional arguments *start* and\n   *end* are interpreted as in slice notation.\n\nstr.decode([encoding[, errors]])\n\n   Decodes the string using the codec registered for *encoding*.\n   *encoding* defaults to the default string encoding.  *errors* may\n   be given to set a different error handling scheme.  The default is\n   ``\'strict\'``, meaning that encoding errors raise ``UnicodeError``.\n   Other possible values are ``\'ignore\'``, ``\'replace\'`` and any other\n   name registered via ``codecs.register_error()``, see section *Codec\n   Base Classes*.\n\n   New in version 2.2.\n\n   Changed in version 2.3: Support for other error handling schemes\n   added.\n\n   Changed in version 2.7: Support for keyword arguments added.\n\nstr.encode([encoding[, errors]])\n\n   Return an encoded version of the string.  Default encoding is the\n   current default string encoding.  *errors* may be given to set a\n   different error handling scheme.  The default for *errors* is\n   ``\'strict\'``, meaning that encoding errors raise a\n   ``UnicodeError``.  Other possible values are ``\'ignore\'``,\n   ``\'replace\'``, ``\'xmlcharrefreplace\'``, ``\'backslashreplace\'`` and\n   any other name registered via ``codecs.register_error()``, see\n   section *Codec Base Classes*. For a list of possible encodings, see\n   section *Standard Encodings*.\n\n   New in version 2.0.\n\n   Changed in version 2.3: Support for ``\'xmlcharrefreplace\'`` and\n   ``\'backslashreplace\'`` and other error handling schemes added.\n\n   Changed in version 2.7: Support for keyword arguments added.\n\nstr.endswith(suffix[, start[, end]])\n\n   Return ``True`` if the string ends with the specified *suffix*,\n   otherwise return ``False``.  *suffix* can also be a tuple of\n   suffixes to look for.  With optional *start*, test beginning at\n   that position.  With optional *end*, stop comparing at that\n   position.\n\n   Changed in version 2.5: Accept tuples as *suffix*.\n\nstr.expandtabs([tabsize])\n\n   Return a copy of the string where all tab characters are replaced\n   by one or more spaces, depending on the current column and the\n   given tab size.  Tab positions occur every *tabsize* characters\n   (default is 8, giving tab positions at columns 0, 8, 16 and so on).\n   To expand the string, the current column is set to zero and the\n   string is examined character by character.  If the character is a\n   tab (``\\t``), one or more space characters are inserted in the\n   result until the current column is equal to the next tab position.\n   (The tab character itself is not copied.)  If the character is a\n   newline (``\\n``) or return (``\\r``), it is copied and the current\n   column is reset to zero.  Any other character is copied unchanged\n   and the current column is incremented by one regardless of how the\n   character is represented when printed.\n\n   >>> \'01\\t012\\t0123\\t01234\'.expandtabs()\n   \'01      012     0123    01234\'\n   >>> \'01\\t012\\t0123\\t01234\'.expandtabs(4)\n   \'01  012 0123    01234\'\n\nstr.find(sub[, start[, end]])\n\n   Return the lowest index in the string where substring *sub* is\n   found, such that *sub* is contained in the slice ``s[start:end]``.\n   Optional arguments *start* and *end* are interpreted as in slice\n   notation.  Return ``-1`` if *sub* is not found.\n\n   Note: The ``find()`` method should be used only if you need to know the\n     position of *sub*.  To check if *sub* is a substring or not, use\n     the ``in`` operator:\n\n        >>> \'Py\' in \'Python\'\n        True\n\nstr.format(*args, **kwargs)\n\n   Perform a string formatting operation.  The string on which this\n   method is called can contain literal text or replacement fields\n   delimited by braces ``{}``.  Each replacement field contains either\n   the numeric index of a positional argument, or the name of a\n   keyword argument.  Returns a copy of the string where each\n   replacement field is replaced with the string value of the\n   corresponding argument.\n\n   >>> "The sum of 1 + 2 is {0}".format(1+2)\n   \'The sum of 1 + 2 is 3\'\n\n   See *Format String Syntax* for a description of the various\n   formatting options that can be specified in format strings.\n\n   This method of string formatting is the new standard in Python 3,\n   and should be preferred to the ``%`` formatting described in\n   *String Formatting Operations* in new code.\n\n   New in version 2.6.\n\nstr.index(sub[, start[, end]])\n\n   Like ``find()``, but raise ``ValueError`` when the substring is not\n   found.\n\nstr.isalnum()\n\n   Return true if all characters in the string are alphanumeric and\n   there is at least one character, false otherwise.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.isalpha()\n\n   Return true if all characters in the string are alphabetic and\n   there is at least one character, false otherwise.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.isdigit()\n\n   Return true if all characters in the string are digits and there is\n   at least one character, false otherwise.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.islower()\n\n   Return true if all cased characters [4] in the string are lowercase\n   and there is at least one cased character, false otherwise.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.isspace()\n\n   Return true if there are only whitespace characters in the string\n   and there is at least one character, false otherwise.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.istitle()\n\n   Return true if the string is a titlecased string and there is at\n   least one character, for example uppercase characters may only\n   follow uncased characters and lowercase characters only cased ones.\n   Return false otherwise.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.isupper()\n\n   Return true if all cased characters [4] in the string are uppercase\n   and there is at least one cased character, false otherwise.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.join(iterable)\n\n   Return a string which is the concatenation of the strings in the\n   *iterable* *iterable*.  The separator between elements is the\n   string providing this method.\n\nstr.ljust(width[, fillchar])\n\n   Return the string left justified in a string of length *width*.\n   Padding is done using the specified *fillchar* (default is a\n   space).  The original string is returned if *width* is less than or\n   equal to ``len(s)``.\n\n   Changed in version 2.4: Support for the *fillchar* argument.\n\nstr.lower()\n\n   Return a copy of the string with all the cased characters [4]\n   converted to lowercase.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.lstrip([chars])\n\n   Return a copy of the string with leading characters removed.  The\n   *chars* argument is a string specifying the set of characters to be\n   removed.  If omitted or ``None``, the *chars* argument defaults to\n   removing whitespace.  The *chars* argument is not a prefix; rather,\n   all combinations of its values are stripped:\n\n   >>> \'   spacious   \'.lstrip()\n   \'spacious   \'\n   >>> \'www.example.com\'.lstrip(\'cmowz.\')\n   \'example.com\'\n\n   Changed in version 2.2.2: Support for the *chars* argument.\n\nstr.partition(sep)\n\n   Split the string at the first occurrence of *sep*, and return a\n   3-tuple containing the part before the separator, the separator\n   itself, and the part after the separator.  If the separator is not\n   found, return a 3-tuple containing the string itself, followed by\n   two empty strings.\n\n   New in version 2.5.\n\nstr.replace(old, new[, count])\n\n   Return a copy of the string with all occurrences of substring *old*\n   replaced by *new*.  If the optional argument *count* is given, only\n   the first *count* occurrences are replaced.\n\nstr.rfind(sub[, start[, end]])\n\n   Return the highest index in the string where substring *sub* is\n   found, such that *sub* is contained within ``s[start:end]``.\n   Optional arguments *start* and *end* are interpreted as in slice\n   notation.  Return ``-1`` on failure.\n\nstr.rindex(sub[, start[, end]])\n\n   Like ``rfind()`` but raises ``ValueError`` when the substring *sub*\n   is not found.\n\nstr.rjust(width[, fillchar])\n\n   Return the string right justified in a string of length *width*.\n   Padding is done using the specified *fillchar* (default is a\n   space). The original string is returned if *width* is less than or\n   equal to ``len(s)``.\n\n   Changed in version 2.4: Support for the *fillchar* argument.\n\nstr.rpartition(sep)\n\n   Split the string at the last occurrence of *sep*, and return a\n   3-tuple containing the part before the separator, the separator\n   itself, and the part after the separator.  If the separator is not\n   found, return a 3-tuple containing two empty strings, followed by\n   the string itself.\n\n   New in version 2.5.\n\nstr.rsplit([sep[, maxsplit]])\n\n   Return a list of the words in the string, using *sep* as the\n   delimiter string. If *maxsplit* is given, at most *maxsplit* splits\n   are done, the *rightmost* ones.  If *sep* is not specified or\n   ``None``, any whitespace string is a separator.  Except for\n   splitting from the right, ``rsplit()`` behaves like ``split()``\n   which is described in detail below.\n\n   New in version 2.4.\n\nstr.rstrip([chars])\n\n   Return a copy of the string with trailing characters removed.  The\n   *chars* argument is a string specifying the set of characters to be\n   removed.  If omitted or ``None``, the *chars* argument defaults to\n   removing whitespace.  The *chars* argument is not a suffix; rather,\n   all combinations of its values are stripped:\n\n   >>> \'   spacious   \'.rstrip()\n   \'   spacious\'\n   >>> \'mississippi\'.rstrip(\'ipz\')\n   \'mississ\'\n\n   Changed in version 2.2.2: Support for the *chars* argument.\n\nstr.split([sep[, maxsplit]])\n\n   Return a list of the words in the string, using *sep* as the\n   delimiter string.  If *maxsplit* is given, at most *maxsplit*\n   splits are done (thus, the list will have at most ``maxsplit+1``\n   elements).  If *maxsplit* is not specified or ``-1``, then there is\n   no limit on the number of splits (all possible splits are made).\n\n   If *sep* is given, consecutive delimiters are not grouped together\n   and are deemed to delimit empty strings (for example,\n   ``\'1,,2\'.split(\',\')`` returns ``[\'1\', \'\', \'2\']``).  The *sep*\n   argument may consist of multiple characters (for example,\n   ``\'1<>2<>3\'.split(\'<>\')`` returns ``[\'1\', \'2\', \'3\']``). Splitting\n   an empty string with a specified separator returns ``[\'\']``.\n\n   If *sep* is not specified or is ``None``, a different splitting\n   algorithm is applied: runs of consecutive whitespace are regarded\n   as a single separator, and the result will contain no empty strings\n   at the start or end if the string has leading or trailing\n   whitespace.  Consequently, splitting an empty string or a string\n   consisting of just whitespace with a ``None`` separator returns\n   ``[]``.\n\n   For example, ``\' 1  2   3  \'.split()`` returns ``[\'1\', \'2\', \'3\']``,\n   and ``\'  1  2   3  \'.split(None, 1)`` returns ``[\'1\', \'2   3  \']``.\n\nstr.splitlines([keepends])\n\n   Return a list of the lines in the string, breaking at line\n   boundaries. This method uses the *universal newlines* approach to\n   splitting lines. Line breaks are not included in the resulting list\n   unless *keepends* is given and true.\n\n   For example, ``\'ab c\\n\\nde fg\\rkl\\r\\n\'.splitlines()`` returns\n   ``[\'ab c\', \'\', \'de fg\', \'kl\']``, while the same call with\n   ``splitlines(True)`` returns ``[\'ab c\\n\', \'\\n\', \'de fg\\r\',\n   \'kl\\r\\n\']``.\n\n   Unlike ``split()`` when a delimiter string *sep* is given, this\n   method returns an empty list for the empty string, and a terminal\n   line break does not result in an extra line.\n\nstr.startswith(prefix[, start[, end]])\n\n   Return ``True`` if string starts with the *prefix*, otherwise\n   return ``False``. *prefix* can also be a tuple of prefixes to look\n   for.  With optional *start*, test string beginning at that\n   position.  With optional *end*, stop comparing string at that\n   position.\n\n   Changed in version 2.5: Accept tuples as *prefix*.\n\nstr.strip([chars])\n\n   Return a copy of the string with the leading and trailing\n   characters removed. The *chars* argument is a string specifying the\n   set of characters to be removed. If omitted or ``None``, the\n   *chars* argument defaults to removing whitespace. The *chars*\n   argument is not a prefix or suffix; rather, all combinations of its\n   values are stripped:\n\n   >>> \'   spacious   \'.strip()\n   \'spacious\'\n   >>> \'www.example.com\'.strip(\'cmowz.\')\n   \'example\'\n\n   Changed in version 2.2.2: Support for the *chars* argument.\n\nstr.swapcase()\n\n   Return a copy of the string with uppercase characters converted to\n   lowercase and vice versa.\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.title()\n\n   Return a titlecased version of the string where words start with an\n   uppercase character and the remaining characters are lowercase.\n\n   The algorithm uses a simple language-independent definition of a\n   word as groups of consecutive letters.  The definition works in\n   many contexts but it means that apostrophes in contractions and\n   possessives form word boundaries, which may not be the desired\n   result:\n\n      >>> "they\'re bill\'s friends from the UK".title()\n      "They\'Re Bill\'S Friends From The Uk"\n\n   A workaround for apostrophes can be constructed using regular\n   expressions:\n\n      >>> import re\n      >>> def titlecase(s):\n      ...     return re.sub(r"[A-Za-z]+(\'[A-Za-z]+)?",\n      ...                   lambda mo: mo.group(0)[0].upper() +\n      ...                              mo.group(0)[1:].lower(),\n      ...                   s)\n      ...\n      >>> titlecase("they\'re bill\'s friends.")\n      "They\'re Bill\'s Friends."\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.translate(table[, deletechars])\n\n   Return a copy of the string where all characters occurring in the\n   optional argument *deletechars* are removed, and the remaining\n   characters have been mapped through the given translation table,\n   which must be a string of length 256.\n\n   You can use the ``maketrans()`` helper function in the ``string``\n   module to create a translation table. For string objects, set the\n   *table* argument to ``None`` for translations that only delete\n   characters:\n\n   >>> \'read this short text\'.translate(None, \'aeiou\')\n   \'rd ths shrt txt\'\n\n   New in version 2.6: Support for a ``None`` *table* argument.\n\n   For Unicode objects, the ``translate()`` method does not accept the\n   optional *deletechars* argument.  Instead, it returns a copy of the\n   *s* where all characters have been mapped through the given\n   translation table which must be a mapping of Unicode ordinals to\n   Unicode ordinals, Unicode strings or ``None``. Unmapped characters\n   are left untouched. Characters mapped to ``None`` are deleted.\n   Note, a more flexible approach is to create a custom character\n   mapping codec using the ``codecs`` module (see ``encodings.cp1251``\n   for an example).\n\nstr.upper()\n\n   Return a copy of the string with all the cased characters [4]\n   converted to uppercase.  Note that ``str.upper().isupper()`` might\n   be ``False`` if ``s`` contains uncased characters or if the Unicode\n   category of the resulting character(s) is not "Lu" (Letter,\n   uppercase), but e.g. "Lt" (Letter, titlecase).\n\n   For 8-bit strings, this method is locale-dependent.\n\nstr.zfill(width)\n\n   Return the numeric string left filled with zeros in a string of\n   length *width*.  A sign prefix is handled correctly.  The original\n   string is returned if *width* is less than or equal to ``len(s)``.\n\n   New in version 2.2.2.\n\nThe following methods are present only on unicode objects:\n\nunicode.isnumeric()\n\n   Return ``True`` if there are only numeric characters in S,\n   ``False`` otherwise. Numeric characters include digit characters,\n   and all characters that have the Unicode numeric value property,\n   e.g. U+2155, VULGAR FRACTION ONE FIFTH.\n\nunicode.isdecimal()\n\n   Return ``True`` if there are only decimal characters in S,\n   ``False`` otherwise. Decimal characters include digit characters,\n   and all characters that can be used to form decimal-radix numbers,\n   e.g. U+0660, ARABIC-INDIC DIGIT ZERO.\n\n\nString Formatting Operations\n============================\n\nString and Unicode objects have one unique built-in operation: the\n``%`` operator (modulo).  This is also known as the string\n*formatting* or *interpolation* operator.  Given ``format % values``\n(where *format* is a string or Unicode object), ``%`` conversion\nspecifications in *format* are replaced with zero or more elements of\n*values*.  The effect is similar to the using ``sprintf()`` in the C\nlanguage.  If *format* is a Unicode object, or if any of the objects\nbeing converted using the ``%s`` conversion are Unicode objects, the\nresult will also be a Unicode object.\n\nIf *format* requires a single argument, *values* may be a single non-\ntuple object. [5]  Otherwise, *values* must be a tuple with exactly\nthe number of items specified by the format string, or a single\nmapping object (for example, a dictionary).\n\nA conversion specifier contains two or more characters and has the\nfollowing components, which must occur in this order:\n\n1. The ``\'%\'`` character, which marks the start of the specifier.\n\n2. Mapping key (optional), consisting of a parenthesised sequence of\n   characters (for example, ``(somename)``).\n\n3. Conversion flags (optional), which affect the result of some\n   conversion types.\n\n4. Minimum field width (optional).  If specified as an ``\'*\'``\n   (asterisk), the actual width is read from the next element of the\n   tuple in *values*, and the object to convert comes after the\n   minimum field width and optional precision.\n\n5. Precision (optional), given as a ``\'.\'`` (dot) followed by the\n   precision.

The advantage of the ``xrange`` type is that an\n``xrange`` object will always take the same amount of memory, no\nmatter the size of the range it represents.  There are no consistent\nperformance advantages.\n\nXRange objects have very little behavior: they only support indexing,\niteration, and the ``len()`` function.\n\n\nMutable Sequence Types\n======================\n\nList and ``bytearray`` objects support additional operations that\nallow in-place modification of the object. Other mutable sequence\ntypes (when added to the language) should also support these\noperations. Strings and tuples are immutable sequence types: such\nobjects cannot be modified once created.

When a negative index is passed as the first parameter to the\n   ``insert()`` method, the list length is added, as for slice\n   indices.  If it is still negative, it is truncated to zero, as for\n   slice indices.\n\n   Changed in version 2.3: Previously, all negative indices were\n   truncated to zero.\n\n6. The ``pop()`` method is only supported by the list and array types.\n   The optional argument *i* defaults to ``-1``, so that by default\n   the last item is removed and returned.\n\n7. The ``sort()`` and ``reverse()`` methods modify the list in place\n   for economy of space when sorting or reversing a large list.  To\n   remind you that they operate by side effect, they don\'t return the\n   sorted or reversed list.\n\n8. The ``sort()`` method takes optional arguments for controlling the\n   comparisons.\n\n   *cmp* specifies a custom comparison function of two arguments (list\n   items) which should return a negative, zero or positive number\n   depending on whether the first argument is considered smaller than,\n   equal to, or larger than the second argument: ``cmp=lambda x,y:\n   cmp(x.lower(), y.lower())``.  The default value is ``None``.\n\n   *key* specifies a function of one argument that is used to extract\n   a comparison key from each list element: ``key=str.lower``.  The\n   default value is ``None``.\n\n   *reverse* is a boolean value.  If set to ``True``, then the list\n   elements are sorted as if each comparison were reversed.\n\n   In general, the *key* and *reverse* conversion processes are much\n   faster than specifying an equivalent *cmp* function.  This is\n   because *cmp* is called multiple times for each list element while\n   *key* and *reverse* touch each element only once.  Use\n   ``functools.cmp_to_key()`` to convert an old-style *cmp* function\n   to a *key* function.\n\n   Changed in version 2.3: Support for ``None`` as an equivalent to\n   omitting *cmp* was added.\n\n   Changed in version 2.4: Support for *key* and *reverse* was added.\n\n9. Starting with Python 2.3, the ``sort()`` method is guaranteed to be\n   stable.  A sort is stable if it guarantees not to change the\n   relative order of elements that compare equal --- this is helpful\n   for sorting in multiple passes (for example, sort by department,\n   then by salary grade).\n\n10. **CPython implementation detail:** While a list is being sorted,\n    the effect of attempting to mutate, or even inspect, the list is\n    undefined.  The C implementation of Python 2.3 and newer makes the\n    list appear empty for the duration, and raises ``ValueError`` if\n    it can detect that the list has been mutated during a sort.\n',

When a negative\n   index is passed as the second or third parameter to the ``index()``\n   method, the list length is added, as for slice indices.  If it is\n   still negative, it is truncated to zero, as for slice indices.\n\n   Changed in version 2.3: Previously, ``index()`` didn't have\n   arguments for specifying start and stop positions.\n\n5. When a negative index is passed as the first parameter to the\n   ``insert()`` method, the list length is added, as for slice\n   indices.  If it is still negative, it is truncated to zero, as for\n   slice indices.\n\n   Changed in version 2.3: Previously, all negative indices were\n   truncated to zero.\n\n6. The ``pop()`` method is only supported by the list and array types.\n   The optional argument *i* defaults to ``-1``, so that by default\n   the last item is removed and returned.\n\n7. The ``sort()`` and ``reverse()`` methods modify the list in place\n   for economy of space when sorting or reversing a large list.  To\n   remind you that they operate by side effect, they don't return the\n   sorted or reversed list.\n\n8. The ``sort()`` method takes optional arguments for controlling the\n   comparisons.\n\n   *cmp* specifies a custom comparison function of two arguments (list\n   items) which should return a negative, zero or positive number\n   depending on whether the first argument is considered smaller than,\n   equal to, or larger than the second argument: ``cmp=lambda x,y:\n   cmp(x.lower(), y.lower())``.  The default value is ``None``.\n\n   *key* specifies a function of one argument that is used to extract\n   a comparison key from each list element: ``key=str.lower``.  The\n   default value is ``None``.\n\n   *reverse* is a boolean value.  If set to ``True``, then the list\n   elements are sorted as if each comparison were reversed.\n\n   In general, the *key* and *reverse* conversion processes are much\n   faster than specifying an equivalent *cmp* function.  This is\n   because *cmp* is called multiple times for each list element while\n   *key* and *reverse* touch each element only once.  Use\n   ``functools.cmp_to_key()`` to convert an old-style *cmp* function\n   to a *key* function.\n\n   Changed in version 2.3: Support for ``None`` as an equivalent to\n   omitting *cmp* was added.\n\n   Changed in version 2.4: Support for *key* and *reverse* was added.\n\n9. Starting with Python 2.3, the ``sort()`` method is guaranteed to be\n   stable.  A sort is stable if it guarantees not to change the\n   relative order of elements that compare equal --- this is helpful\n   for sorting in multiple passes (for example, sort by department,\n   then by salary grade).\n\n10. **CPython implementation detail:** While a list is being sorted,\n    the effect of attempting to mutate, or even inspect, the list is\n    undefined.  The C implementation of Python 2.3 and newer makes the\n    list appear empty for the duration, and raises ``ValueError`` if\n    it can detect that the list has been mutated during a sort.\n",
- 'unary': '\nUnary arithmetic and bitwise operations\n***************************************\n\nAll unary arithmetic and bitwise operations have the same priority:\n\n   u_expr ::= power | "-" u_expr | "+" u_expr | "~" u_expr\n\nThe unary ``-`` (minus) operator yields the negation of its numeric\nargument.\n\nThe unary ``+`` (plus) operator yields its numeric argument unchanged.\n\nThe unary ``~`` (invert) operator yields the bitwise inversion of its\nplain or long integer argument.  The bitwise inversion of ``x`` is\ndefined as ``-(x+1)``.  It only applies to integral numbers.\n\nIn all three cases, if the argument does not have the proper type, a\n``TypeError`` exception is raised.\n',
- 'while': '\nThe ``while`` statement\n***********************\n\nThe ``while`` statement is used for repeated execution as long as an\nexpression is true:\n\n   while_stmt ::= "while" expression ":" suite\n                  ["else" ":" suite]\n\nThis repeatedly tests the expression and, if it is true, executes the\nfirst suite; if the expression is false (which may be the first time\nit is tested) the suite of the ``else`` clause, if present, is\nexecuted and the loop terminates.\n\nA ``break`` statement executed in the first suite terminates the loop\nwithout executing the ``else`` clause\'s suite.  A ``continue``\nstatement executed in the first suite skips the rest of the suite and\ngoes back to testing the expression.\n',
- 'with': '\nThe ``with`` statement\n**********************\n\nNew in version 2.5.\n\nThe ``with`` statement is used to wrap the execution of a block with\nmethods defined by a context manager (see section *With Statement\nContext Managers*). This allows common\n``try``...``except``...``finally`` usage patterns to be encapsulated\nfor convenient reuse.\n\n   with_stmt ::= "with" with_item ("," with_item)* ":" suite\n   with_item ::= expression ["as" target]\n\nThe execution of the ``with`` statement with one "item" proceeds as\nfollows:\n\n1. The context expression (the expression given in the ``with_item``)\n   is evaluated to obtain a context manager.\n\n2. The context manager\'s ``__exit__()`` is loaded for later use.\n\n3. The context manager\'s ``__enter__()`` method is invoked.\n\n4. If a target was included in the ``with`` statement, the return\n   value from ``__enter__()`` is assigned to it.\n\n   Note: The ``with`` statement guarantees that if the ``__enter__()``\n     method returns without an error, then ``__exit__()`` will always\n     be called. Thus, if an error occurs during the assignment to the\n     target list, it will be treated the same as an error occurring\n     within the suite would be. See step 6 below.\n\n5. The suite is executed.\n\n6. The context manager\'s ``__exit__()`` method is invoked. If an\n   exception caused the suite to be exited, its type, value, and\n   traceback are passed as arguments to ``__exit__()``. Otherwise,\n   three ``None`` arguments are supplied.\n\n   If the suite was exited due to an exception, and the return value\n   from the ``__exit__()`` method was false, the exception is\n   reraised. If the return value was true, the exception is\n   suppressed, and execution continues with the statement following\n   the ``with`` statement.\n\n   If the suite was exited for any reason other than an exception, the\n   return value from ``__exit__()`` is ignored, and execution proceeds\n   at the normal location for the kind of exit that was taken.\n\nWith more than one item, the context managers are processed as if\nmultiple ``with`` statements were nested:\n\n   with A() as a, B() as b:\n       suite\n\nis equivalent to\n\n   with A() as a:\n       with B() as b:\n           suite\n\nNote: In Python 2.5, the ``with`` statement is only allowed when the\n  ``with_statement`` feature has been enabled.  It is always enabled\n  in Python 2.6.\n\nChanged in version 2.7: Support for multiple context expressions.\n\nSee also:\n\n   **PEP 0343** - The "with" statement\n      The specification, background, and examples for the Python\n      ``with`` statement.\n',
- 'yield': '\nThe ``yield`` statement\n***********************\n\n   yield_stmt ::= yield_expression\n\nThe ``yield`` statement is only used when defining a generator\nfunction, and is only used in the body of the generator function.\nUsing a ``yield`` statement in a function definition is sufficient to\ncause that definition to create a generator function instead of a\nnormal function.\n\nWhen a generator function is called, it returns an iterator known as a\ngenerator iterator, or more commonly, a generator.  The body of the\ngenerator function is executed by calling the generator\'s ``next()``\nmethod repeatedly until it raises an exception.\n\nWhen a ``yield`` statement is executed, the state of the generator is\nfrozen and the value of ``expression_list`` is returned to\n``next()``\'s caller.  By "frozen" we mean that all local state is\nretained, including the current bindings of local variables, the\ninstruction pointer, and the internal evaluation stack: enough\ninformation is saved so that the next time ``next()`` is invoked, the\nfunction can proceed exactly as if the ``yield`` statement were just\nanother external call.\n\nAs of Python version 2.5, the ``yield`` statement is now allowed in\nthe ``try`` clause of a ``try`` ...  ``finally`` construct.  If the\ngenerator is not resumed before it is finalized (by reaching a zero\nreference count or by being garbage collected), the generator-\niterator\'s ``close()`` method will be called, allowing any pending\n``finally`` clauses to execute.\n\nFor full details of ``yield`` semantics, refer to the *Yield\nexpressions* section.\n\nNote: In Python 2.2, the ``yield`` statement was only allowed when the\n  ``generators`` feature has been enabled.  This ``__future__`` import\n  statement was used to enable the feature:\n\n     from __future__ import generators\n\nSee also:\n\n   **PEP 0255** - Simple Generators\n      The proposal for adding generators and the ``yield`` statement\n      to Python.\n\n   **PEP 0342** - Coroutines via Enhanced Generators\n      The proposal that, among other generator enhancements, proposed\n      allowing ``yield`` to appear inside a ``try`` ... ``finally``\n      block.\n'}

-* It is one of the most extensively tested generators in existence.
-* Without a direct way to compute N steps forward, the semantics of

-r"""Support for regular expressions (RE).
-
-This module provides regular expression matching operations similar to
-those found in Perl.  It supports both 8-bit and Unicode strings; both
-the pattern and the strings being processed can contain null bytes and
-characters outside the US ASCII range.
-
-Regular expressions can contain both special and ordinary characters.
-Most ordinary characters, like "A", "a", or "0", are the simplest
-regular expressions; they simply match themselves.  You can
-concatenate ordinary characters, so last matches the string 'last'.
-
-The special characters are:
-    "."      Matches any character except a newline.
-    "^"      Matches the start of the string.
-    "$"      Matches the end of the string or just before the newline at
-             the end of the string.
-    "*"      Matches 0 or more (greedy) repetitions of the preceding RE.
-             Greedy means that it will match as many repetitions as possible.
-    "+"      Matches 1 or more (greedy) repetitions of the preceding RE.
-    "?"      Matches 0 or 1 (greedy) of the preceding RE.
-    *?,+?,?? Non-greedy versions of the previous three special characters.
-    {m,n}    Matches from m to n repetitions of the preceding RE.
-    {m,n}?   Non-greedy version of the above.
-    "\\"     Either escapes special characters or signals a special sequence.
-    []       Indicates a set of characters.
-             A "^" as the first character indicates a complementing set.
-    "|"      A|B, creates an RE that will match either A or B.
-    (...)    Matches the RE inside the parentheses.
-             The contents can be retrieved or matched later in the string.
-    (?iLmsux) Set the I, L, M, S, U, or X flag for the RE (see below).
-    (?:...)  Non-grouping version of regular parentheses.
-    (?P<name>...) The substring matched by the group is accessible by name.
-    (?P=name)     Matches the text matched earlier by the group named name.
-    (?#...)  A comment; ignored.
-    (?=...)  Matches if ... matches next, but doesn't consume the string.
-    (?!...)  Matches if ... doesn't match next.
-    (?<=...) Matches if preceded by ... (must be fixed length).
-    (?<!...) Matches if not preceded by ... (must be fixed length).
-    (?(id/name)yes|no) Matches yes pattern if the group with id/name matched,
-                       the (optional) no pattern otherwise.
-
-The special sequences consist of "\\" and a character from the list
-below.  If the ordinary character is not on the list, then the
-resulting RE will match the second character.
-    \number  Matches the contents of the group of the same number.
-    \A       Matches only at the start of the string.
-    \Z       Matches only at the end of the string.
-    \b       Matches the empty string, but only at the start or end of a word.
-    \B       Matches the empty string, but not at the start or end of a word.
-    \d       Matches any decimal digit; equivalent to the set [0-9].
-    \D       Matches any non-digit character; equivalent to the set [^0-9].
-    \s       Matches any whitespace character; equivalent to [ \t\n\r\f\v].
-    \S       Matches any non-whitespace character; equiv. to [^ \t\n\r\f\v].
-    \w       Matches any alphanumeric character; equivalent to [a-zA-Z0-9_].
-             With LOCALE, it will match the set [0-9_] plus characters defined
-             as letters for the current locale.
-    \W       Matches the complement of \w.
-    \\       Matches a literal backslash.
-
-This module exports the following functions:
-    match    Match a regular expression pattern to the beginning of a string.
-    search   Search a string for the presence of a pattern.
-    sub      Substitute occurrences of a pattern found in a string.
-    subn     Same as sub, but also return the number of substitutions made.
-    split    Split a string by the occurrences of a pattern.
-    findall  Find all occurrences of a pattern in a string.
-    finditer Return an iterator yielding a match object for each match.
-    compile  Compile a pattern into a RegexObject.
-    purge    Clear the regular expression cache.
-    escape   Backslash all non-alphanumerics in a string.
-
-Some of the functions in this module takes flags as optional parameters:
-    I  IGNORECASE  Perform case-insensitive matching.
-    L  LOCALE      Make \w, \W, \b, \B, dependent on the current locale.
-    M  MULTILINE   "^" matches the beginning of lines (after a newline)
-                   as well as the string.
-                   "$" matches the end of lines (before a newline) as well
-                   as the end of the string.

-
-        The hooks parameter is an instance of the RHooks class or a subclass
-        of it.  If it is omitted or None, the default RHooks class is
-        instantiated.
-
-        Whenever the RExec module searches for a module (even a built-in one)
-        or reads a module's code, it doesn't actually go out to the file
-        system itself.  Rather, it calls methods of an RHooks instance that
-        was passed to or created by its constructor.  (Actually, the RExec
-        object doesn't make these calls --- they are made by a module loader
-        object that's part of the RExec object.  This allows another level of
-        flexibility, which can be useful when changing the mechanics of
-        import within the restricted environment.)
-
-        By providing an alternate RHooks object, we can control the file
-        system accesses made to import a module, without changing the
-        actual algorithm that controls the order in which those accesses are
-        made.  For instance, we could substitute an RHooks object that
-        passes all filesystem requests to a file server elsewhere, via some
-        RPC mechanism such as ILU.  Grail's applet loader uses this to support
-        importing applets from a URL for a directory.
-
-        If the verbose parameter is true, additional debugging output may be
-        sent to standard output.

-"""RFC 2822 message manipulation.
-
-Note: This is only a very rough sketch of a full RFC-822 parser; in particular
-the tokenizing of addresses does not adhere to all the quoting rules.
-
-Note: RFC 2822 is a long awaited update to RFC 822.  This module should
-conform to RFC 2822, and is thus mis-named (it's not worth renaming it).  Some
-effort at RFC 2822 updates have been made, but a thorough audit has not been
-performed.  Consider any RFC 2822 non-conformance to be a bug.
-
-    RFC 2822: http://www.faqs.org/rfcs/rfc2822.html
-    RFC 822 : http://www.faqs.org/rfcs/rfc822.html (obsolete)
-
-Directions for use:
-
-To create a Message object: first open a file, e.g.:
-
-  fp = open(file, 'r')
-
-You can use any other legal way of getting an open file object, e.g. use
-sys.stdin or call os.popen().  Then pass the open file object to the Message()
-constructor:
-
-  m = Message(fp)
-
-This class can work with any input object that supports a readline method.  If
-the input object has seek and tell capability, the rewindbody method will
-work; also illegal lines will be pushed back onto the input stream.  If the
-input object lacks seek but has an `unread' method that can push back a line
-of input, Message will use that to push back illegal lines.  Thus this class
-can be used to parse messages coming from a buffered stream.
-
-The optional `seekable' argument is provided as a workaround for certain stdio
-libraries in which tell() discards buffered data before discovering that the
-lseek() system call doesn't work.  For maximum portability, you should set the
-seekable argument to zero to prevent that initial \code{tell} when passing in
-an unseekable object such as a file object created from a socket object.  If
-it is 1 on entry -- which it is by default -- the tell() method of the open
-file object is called once; if this raises an exception, seekable is reset to
-0.  For other nonzero values of seekable, this test is not made.
-
-To get the text of a particular header there are several methods:
-
-  str = m.getheader(name)
-  str = m.getrawheader(name)
-
-where name is the name of the header, e.g. 'Subject'.  The difference is that
-getheader() strips the leading and trailing whitespace, while getrawheader()
-doesn't.  Both functions retain embedded whitespace (including newlines)
-exactly as they are specified in the header, and leave the case of the text
-unchanged.
-
-For addresses and address lists there are functions
-
-  realname, mailaddress = m.getaddr(name)
-  list = m.getaddrlist(name)
-
-where the latter returns a list of (realname, mailaddr) tuples.
-
-There is also a method
-
-  time = m.getdate(name)
-
-which parses a Date-like field and returns a time-compatible tuple,
-i.e. a tuple such as returned by time.localtime() or accepted by
-time.mktime().
-
-See the class definition for lower level access methods.
-
-There are also some utility functions here.

-Each instance is parametrized with two functions, one that is

-implement a delay.  You can implement real-time scheduling by
-substituting time and sleep from built-in module time, or you can
-implement simulated time by writing your own functions.  This can
-also be used to integrate scheduling with STDWIN events; the delay
-function is allowed to modify the queue.  Time can be expressed as
-integers or floating point numbers, as long as it is consistent.
-
-Events are specified by tuples (time, priority, action, argument).
-As in UNIX, lower priority numbers mean higher priority; in this
-way the queue can be maintained as a priority queue.  Execution of the
-event means calling the action function, passing it the argument
-sequence in "argument" (remember that in Python, multiple function
-arguments are be packed in a sequence).
-The action function may be an instance method so it
-has another way to reference private data (besides global variables).

-"""Classes to represent arbitrary sets (including sets of sets).
-
-This module implements sets using dictionaries whose values are
-ignored.  The usual operations (union, intersection, deletion, etc.)
-are provided as both methods and operators.
-
-Important: sets are not sequences!  While they support 'x in s',
-'len(s)', and 'for x in s', none of those operations are unique for
-sequences; for example, mappings support all three as well.  The
-characteristic operation for sequences is subscripting with small
-integers: s[i], for i in range(len(s)).  Sets don't support
-subscripting at all.  Also, sequences allow multiple occurrences and
-their elements have a definite order; sets on the other hand don't
-record multiple occurrences and don't remember the order of element
-insertion (which is why they don't support s[i]).
-
-The following classes are provided:
-
-BaseSet -- All the operations common to both mutable and immutable
-    sets. This is an abstract class, not meant to be directly
-    instantiated.
-
-Set -- Mutable sets, subclass of BaseSet; not hashable.
-
-ImmutableSet -- Immutable sets, subclass of BaseSet; hashable.
-    An iterable argument is mandatory to create an ImmutableSet.
-
-_TemporarilyImmutableSet -- A wrapper around a Set, hashable,
-    giving the same hash value as the immutable set equivalent
-    would have.  Do not use this class directly.
-
-Only hashable objects can be added to a Set. In particular, you cannot
-really add a Set as an element to another Set; if you try, what is
-actually added is an ImmutableSet built from it (it compares equal to
-the one you tried adding).
-
-When you ask if `x in y' where x is a Set and y is a Set or
-ImmutableSet, x is wrapped into a _TemporarilyImmutableSet z, and
-what's tested is actually `z in y'.

-        0.1.0 pil mod   March 10, 2009
-
-                        Renamed display profile to proof profile. The proof
-                        profile is the profile of the device that is being
-                        simulated, not the profile of the device which is
-                        actually used to display/print the final simulation
-                        (that'd be the output profile) - also see LCMSAPI.txt
-                        input colorspace -> using 'renderingIntent' -> proof
-                        colorspace -> using 'proofRenderingIntent' -> output
-                        colorspace
-
-                        Added LCMS FLAGS support.
-                        Added FLAGS["SOFTPROOFING"] as default flag for
-                        buildProofTransform (otherwise the proof profile/intent
-                        would be ignored).
-
-        0.1.0 pil       March 2009 - added to PIL, as PIL.ImageCms
-
-        0.0.2 alpha     Jan 6, 2002
-
-                        Added try/except statements arount type() checks of
-                        potential CObjects... Python won't let you use type()
-                        on them, and raises a TypeError (stupid, if you ask me!)
-
-                        Added buildProofTransformFromOpenProfiles() function.
-                        Additional fixes in DLL, see DLL code for details.
-
-        0.0.1 alpha     first public release, Dec. 26, 2002
-
-    Known to-do list with current version (of Python interface, not pyCMSdll):
-
-        none

-
-    The reason pyCMS returns a class object rather than a handle directly
-    to the transform is that it needs to keep track of the PIL input/output
-    modes that the transform is meant for.  These attributes are stored in
-    the "inMode" and "outMode" attributes of the object (which can be
-    manually overridden if you really want to, but I don't know of any
-    time that would be of use, or would even work).

-    output device is a monitor, or a dye-sub printer (etc.), and the simulated
-    device is something more expensive, complicated, or time consuming
-    (making it difficult to make a real print for color judgement purposes).
-
-    Soft-proofing basically functions by adjusting the colors on the
-    output device to match the colors of the device being simulated. However,
-    when the simulated device has a much wider gamut than the output
-    device, you may obtain marginal results.

-#
-# stuff to deal with OLE2 Structured Storage files.  this module is
-# used by PIL to read Image Composer and FlashPix files, but can also
-# be used to read other files of this type.
-#
-# History:
-# 1997-01-20 fl   Created
-# 1997-01-22 fl   Fixed 64-bit portability quirk
-# 2003-09-09 fl   Fixed typo in OleFileIO.loadfat (noted by Daniel Haertle)
-# 2004-02-29 fl   Changed long hex constants to signed integers
-#
-# Notes:
-# FIXME: sort out sign problem (eliminate long hex constants)
-# FIXME: change filename to use "a/b/c" instead of ["a", "b", "c"]
-# FIXME: provide a glob mechanism function (using fnmatchcase)
-#
-# Literature:
-#
-# "FlashPix Format Specification, Appendix A", Kodak and Microsoft,
-#  September 1996.

-# "If this document and functionality of the Software conflict,
-#  the actual functionality of the Software represents the correct
-#  functionality" -- Microsoft, in the OLE format specification

-# TIFF file handling
-#
-# TIFF is a flexible, if somewhat aged, image file format originally
-# defined by Aldus.  Although TIFF supports a wide variety of pixel
-# layouts and compression methods, the name doesn't really stand for
-# "thousands of incompatible file formats," it just feels that way.
-#
-# To read TIFF data from a stream, the stream must be seekable.  For
-# progressive decoding, make sure to use TIFF files where the tag
-# directory is placed first in the file.
-#
-# History:
-# 1995-09-01 fl   Created
-# 1996-05-04 fl   Handle JPEGTABLES tag
-# 1996-05-18 fl   Fixed COLORMAP support
-# 1997-01-05 fl   Fixed PREDICTOR support
-# 1997-08-27 fl   Added support for rational tags (from Perry Stoll)
-# 1998-01-10 fl   Fixed seek/tell (from Jan Blom)
-# 1998-07-15 fl   Use private names for internal variables
-# 1999-06-13 fl   Rewritten for PIL 1.0 (1.0)
-# 2000-10-11 fl   Additional fixes for Python 2.0 (1.1)
-# 2001-04-17 fl   Fixed rewind support (seek to frame 0) (1.2)
-# 2001-05-12 fl   Added write support for more tags (from Greg Couch) (1.3)
-# 2001-12-18 fl   Added workaround for broken Matrox library
-# 2002-01-18 fl   Don't mess up if photometric tag is missing (D. Alan Stewart)
-# 2003-05-19 fl   Check FILLORDER tag
-# 2003-09-26 fl   Added RGBa support
-# 2004-02-24 fl   Added DPI support; fixed rational write support
-# 2005-02-07 fl   Added workaround for broken Corel Draw 10 files
-# 2006-01-09 fl   Added support for float/double tags (from Russell Nelson)

-        ==========
-        
-        The Python SQL Toolkit and Object Relational Mapper
-        
-        Introduction
-        -------------
-        
-        SQLAlchemy is the Python SQL toolkit and Object Relational Mapper
-        that gives application developers the full power and
-        flexibility of SQL. SQLAlchemy provides a full suite
-        of well known enterprise-level persistence patterns,
-        designed for efficient and high-performing database
-        access, adapted into a simple and Pythonic domain
-        language.
-        
-        Major SQLAlchemy features include:
-        
-        * An industrial strength ORM, built 
-          from the core on the identity map, unit of work,
-          and data mapper patterns.   These patterns
-          allow transparent persistence of objects 
-          using a declarative configuration system.
-          Domain models
-          can be constructed and manipulated naturally,
-          and changes are synchronized with the
-          current transaction automatically.
-        * A relationally-oriented query system, exposing
-          the full range of SQL's capabilities 
-          explicitly, including joins, subqueries, 
-          correlation, and most everything else, 
-          in terms of the object model.
-          Writing queries with the ORM uses the same 
-          techniques of relational composition you use 
-          when writing SQL.  While you can drop into
-          literal SQL at any time, it's virtually never
-          needed.
-        * A comprehensive and flexible system 
-          of eager loading for related collections and objects.
-          Collections are cached within a session,
-          and can be loaded on individual access, all 
-          at once using joins, or by query per collection
-          across the full result set.
-        * A Core SQL construction system and DBAPI 
-          interaction layer.  The SQLAlchemy Core is
-          separate from the ORM and is a full database
-          abstraction layer in its own right, and includes
-          an extensible Python-based SQL expression 
-          language, schema metadata, connection pooling, 
-          type coercion, and custom types.
-        * All primary and foreign key constraints are 
-          assumed to be composite and natural.  Surrogate
-          integer primary keys are of course still the 
-          norm, but SQLAlchemy never assumes or hardcodes
-          to this model.
-        * Database introspection and generation.  Database
-          schemas can be "reflected" in one step into
-          Python structures representing database metadata;
-          those same structures can then generate 
-          CREATE statements right back out - all within
-          the Core, independent of the ORM.
-        
-        SQLAlchemy's philosophy:
-        
-        * SQL databases behave less and less like object
-          collections the more size and performance start to
-          matter; object collections behave less and less like
-          tables and rows the more abstraction starts to matter.
-          SQLAlchemy aims to accommodate both of these
-          principles.
-        * An ORM doesn't need to hide the "R".   A relational
-          database provides rich, set-based functionality
-          that should be fully exposed.   SQLAlchemy's
-          ORM provides an open-ended set of patterns
-          that allow a developer to construct a custom
-          mediation layer between a domain model and 
-          a relational schema, turning the so-called
-          "object relational impedance" issue into
-          a distant memory.
-        * The developer, in all cases, makes all decisions
-          regarding the design, structure, and naming conventions
-          of both the object model as well as the relational
-          schema.   SQLAlchemy only provides the means
-          to automate the execution of these decisions.
-        * With SQLAlchemy, there's no such thing as 
-          "the ORM generated a bad query" - you 
-          retain full control over the structure of 
-          queries, including how joins are organized,
-          how subqueries and correlation is used, what 
-          columns are requested.  Everything SQLAlchemy
-          does is ultimately the result of a developer-
-          initiated decision.
-        * Don't use an ORM if the problem doesn't need one.
-          SQLAlchemy consists of a Core and separate ORM
-          component.   The Core offers a full SQL expression
-          language that allows Pythonic construction 
-          of SQL constructs that render directly to SQL
-          strings for a target database, returning
-          result sets that are essentially enhanced DBAPI
-          cursors.
-        * Transactions should be the norm.  With SQLAlchemy's
-          ORM, nothing goes to permanent storage until
-          commit() is called.  SQLAlchemy encourages applications
-          to create a consistent means of delineating
-          the start and end of a series of operations.
-        * Never render a literal value in a SQL statement.
-          Bound parameters are used to the greatest degree
-          possible, allowing query optimizers to cache 
-          query plans effectively and making SQL injection
-          attacks a non-issue.

-Metadata-Version: 1.0
-Name: ed25519
-Version: 1.2
-Summary: Ed25519 public-key signatures
-Home-page: https://github.com/warner/python-ed25519
-Author: Brian Warner
-Author-email: warner-python-ed25519@lothar.com
-License: MIT
-Description: Python bindings to the Ed25519 public-key signature system.
-        
-        This offers a comfortable python interface to a C implementation of the
-        Ed25519 public-key signature system (http://ed25519.cr.yp.to/), using the
-        portable 'ref' code from the 'SUPERCOP' benchmarking suite.
-        
-        This system provides high (128-bit) security, short (32-byte) keys, short
-        (64-byte) signatures, and fast (2-6ms) operation. Please see the README for
-        more details.
-

-        Quickstart
-        ==========
-        
-        First, :doc:`Install pip <installing>`.
-        
-        Install a package from `PyPI`_:
-        
-        ::
-        
-          $ pip install SomePackage
-            [...]
-            Successfully installed SomePackage
-        
-        Show what files were installed:
-        
-        ::
-        
-          $ pip show --files SomePackage
-            Name: SomePackage
-            Version: 1.0
-            Location: /my/env/lib/pythonx.x/site-packages
-            Files:
-             ../somepackage/__init__.py
-             [...]
-        
-        List what packages are outdated:
-        
-        ::
-        
-          $ pip list --outdated
-            SomePackage (Current: 1.0 Latest: 2.0)
-        
-        Upgrade a package:
-        
-        ::
-        
-          $ pip install --upgrade SomePackage
-            [...]
-            Found existing installation: SomePackage 1.0
-            Uninstalling SomePackage:
-              Successfully uninstalled SomePackage
-            Running setup.py install for SomePackage
-            Successfully installed SomePackage
-        
-        Uninstall a package:
-        
-        ::
-        
-          $ pip uninstall SomePackage
-            Uninstalling SomePackage:

-.. dialect:: firebird
-    :name: Firebird
-
-Firebird Dialects
------------------
-
-Firebird offers two distinct dialects_ (not to be confused with a
-SQLAlchemy ``Dialect``):
-
-dialect 1
-  This is the old syntax and behaviour, inherited from Interbase pre-6.0.
-
-dialect 3
-  This is the newer and supported syntax, introduced in Interbase 6.0.
-
-The SQLAlchemy Firebird dialect detects these versions and
-adjusts its representation of SQL accordingly.  However,
-support for dialect 1 is not well tested and probably has
-incompatibilities.
-
-Locking Behavior
-----------------
-
-Firebird locks tables aggressively.  For this reason, a DROP TABLE may
-hang until other transactions are released.  SQLAlchemy does its best
-to release transactions as quickly as possible.  The most common cause
-of hanging transactions is a non-fully consumed result set, i.e.::
-
-    result = engine.execute("select * from table")
-    row = result.fetchone()
-    return
-
-Where above, the ``ResultProxy`` has not been fully consumed.  The
-connection will be returned to the pool and the transactional state
-rolled back once the Python garbage collector reclaims the objects
-which hold onto the connection, which often occurs asynchronously.
-The above use case can be alleviated by calling ``first()`` on the
-``ResultProxy`` which will fetch the first row and immediately close
-all remaining cursor/connection resources.
-
-RETURNING support
------------------
-
-Firebird 2.0 supports returning a result set from inserts, and 2.1
-extends that to deletes and updates. This is generically exposed by
-the SQLAlchemy ``returning()`` method, such as::
-
-    # INSERT..RETURNING
-    result = table.insert().returning(table.c.col1, table.c.col2).\\
-                   values(name='foo')
-    print result.fetchall()
-
-    # UPDATE..RETURNING
-    raises = empl.update().returning(empl.c.id, empl.c.salary).\\
-                  where(empl.c.sales>100).\\
-                  values(dict(salary=empl.c.salary * 1.1))
-    print raises.fetchall()

-.. dialect:: firebird+fdb
-    :name: fdb
-    :dbapi: pyodbc
-    :connectstring: firebird+fdb://user:password@host:port/path/to/db[?key=value&key=value...]
-    :url: http://pypi.python.org/pypi/fdb/
-
-    fdb is a kinterbasdb compatible DBAPI for Firebird.
-
-    .. versionadded:: 0.8 - Support for the fdb Firebird driver.
-
-    .. versionchanged:: 0.9 - The fdb dialect is now the default dialect
-       under the ``firebird://`` URL space, as ``fdb`` is now the official
-       Python driver for Firebird.
-
-Arguments
-----------
-
-The ``fdb`` dialect is based on the :mod:`sqlalchemy.dialects.firebird.kinterbasdb`
-dialect, however does not accept every argument that Kinterbasdb does.
-
-* ``enable_rowcount`` - True by default, setting this to False disables
-  the usage of "cursor.rowcount" with the
-  Kinterbasdb dialect, which SQLAlchemy ordinarily calls upon automatically
-  after any UPDATE or DELETE statement.   When disabled, SQLAlchemy's
-  ResultProxy will return -1 for result.rowcount.   The rationale here is
-  that Kinterbasdb requires a second round trip to the database when
-  .rowcount is called -  since SQLA's resultproxy automatically closes
-  the cursor after a non-result-returning statement, rowcount must be
-  called, if at all, before the result object is returned.   Additionally,
-  cursor.rowcount may not return correct results with older versions
-  of Firebird, and setting this flag to False will also cause the
-  SQLAlchemy ORM to ignore its usage. The behavior can also be controlled on a
-  per-execution basis using the ``enable_rowcount`` option with
-  :meth:`.Connection.execution_options`::
-
-      conn = engine.connect().execution_options(enable_rowcount=True)
-      r = conn.execute(stmt)
-      print r.rowcount
-
-* ``retaining`` - False by default.   Setting this to True will pass the
-  ``retaining=True`` keyword argument to the ``.commit()`` and ``.rollback()``
-  methods of the DBAPI connection, which can improve performance in some
-  situations, but apparently with significant caveats.
-  Please read the fdb and/or kinterbasdb DBAPI documentation in order to
-  understand the implications of this flag.
-
-  .. versionadded:: 0.8.2 - ``retaining`` keyword argument specifying
-     transaction retaining behavior - in 0.8 it defaults to ``True``
-     for backwards compatibility.
-
-  .. versionchanged:: 0.9.0 - the ``retaining`` flag defaults to ``False``.
-     In 0.8 it defaulted to ``True``.
-
-  .. seealso::
-
-    http://pythonhosted.org/fdb/usage-guide.html#retaining-transactions - information
-    on the "retaining" flag.

-.. dialect:: mssql
-    :name: Microsoft SQL Server
-
-
-Auto Increment Behavior
------------------------
-
-``IDENTITY`` columns are supported by using SQLAlchemy
-``schema.Sequence()`` objects. In other words::
-
-    from sqlalchemy import Table, Integer, Sequence, Column
-
-    Table('test', metadata,
-           Column('id', Integer,
-                  Sequence('blah',100,10), primary_key=True),
-           Column('name', String(20))
-         ).create(some_engine)
-
-would yield::
-
-   CREATE TABLE test (
-     id INTEGER NOT NULL IDENTITY(100,10) PRIMARY KEY,
-     name VARCHAR(20) NULL,
-     )
-
-Note that the ``start`` and ``increment`` values for sequences are
-optional and will default to 1,1.
-
-Implicit ``autoincrement`` behavior works the same in MSSQL as it
-does in other dialects and results in an ``IDENTITY`` column.
-
-* Support for ``SET IDENTITY_INSERT ON`` mode (automagic on / off for
-  ``INSERT`` s)
-
-* Support for auto-fetching of ``@@IDENTITY/@@SCOPE_IDENTITY()`` on
-  ``INSERT``
-
-Collation Support
------------------
-
-Character collations are supported by the base string types,
-specified by the string argument "collation"::
-
-    from sqlalchemy import VARCHAR
-    Column('login', VARCHAR(32, collation='Latin1_General_CI_AS'))
-
-When such a column is associated with a :class:`.Table`, the
-CREATE TABLE statement for this column will yield::
-
-    login VARCHAR(32) COLLATE Latin1_General_CI_AS NULL
-
-.. versionadded:: 0.8 Character collations are now part of the base string
-   types.
-
-LIMIT/OFFSET Support
---------------------
-
-MSSQL has no support for the LIMIT or OFFSET keysowrds. LIMIT is
-supported directly through the ``TOP`` Transact SQL keyword::
-
-    select.limit
-
-will yield::
-
-    SELECT TOP n
-
-If using SQL Server 2005 or above, LIMIT with OFFSET
-support is available through the ``ROW_NUMBER OVER`` construct.
-For versions below 2005, LIMIT with OFFSET usage will fail.
-
-Nullability
------------
-MSSQL has support for three levels of column nullability. The default
-nullability allows nulls and is explicit in the CREATE TABLE
-construct::
-
-    name VARCHAR(20) NULL
-
-If ``nullable=None`` is specified then no specification is made. In
-other words the database's configured default is used. This will
-render::
-
-    name VARCHAR(20)
-
-If ``nullable`` is ``True`` or ``False`` then the column will be
-``NULL` or ``NOT NULL`` respectively.
-
-Date / Time Handling
---------------------
-DATE and TIME are supported.   Bind parameters are converted
-to datetime.datetime() objects as required by most MSSQL drivers,
-and results are processed from strings if needed.
-The DATE and TIME types are not available for MSSQL 2005 and
-previous - if a server version below 2008 is detected, DDL
-for these types will be issued as DATETIME.
-
-.. _mssql_indexes:
-
-Clustered Index Support
------------------------
-
-The MSSQL dialect supports clustered indexes (and primary keys) via the
-``mssql_clustered`` option.  This option is available to :class:`.Index`,
-:class:`.UniqueConstraint`. and :class:`.PrimaryKeyConstraint`.
-
-To generate a clustered index::
-
-    Index("my_index", table.c.x, mssql_clustered=True)
-
-which renders the index as ``CREATE CLUSTERED INDEX my_index ON table (x)``.
-
-.. versionadded:: 0.8
-
-To generate a clustered primary key use::
-
-    Table('my_table', metadata,
-          Column('x', ...),
-          Column('y', ...),
-          PrimaryKeyConstraint("x", "y", mssql_clustered=True))
-
-which will render the table, for example, as::
-
-  CREATE TABLE my_table (x INTEGER NOT NULL, y INTEGER NOT NULL, PRIMARY KEY CLUSTERED (x, y))
-
-Similarly, we can generate a clustered unique constraint using::
-
-    Table('my_table', metadata,
-          Column('x', ...),
-          Column('y', ...),
-          PrimaryKeyConstraint("x"),
-          UniqueConstraint("y", mssql_clustered=True),
-          )
-
-  .. versionadded:: 0.9.2
-
-MSSQL-Specific Index Options
------------------------------
-
-In addition to clustering, the MSSQL dialect supports other special options
-for :class:`.Index`.
-
-INCLUDE
-^^^^^^^
-
-The ``mssql_include`` option renders INCLUDE(colname) for the given string names::
-
-    Index("my_index", table.c.x, mssql_include=['y'])
-
-would render the index as ``CREATE INDEX my_index ON table (x) INCLUDE (y)``
-
-.. versionadded:: 0.8
-
-Index ordering
-^^^^^^^^^^^^^^
-
-Index ordering is available via functional expressions, such as::
-
-    Index("my_index", table.c.x.desc())
-
-would render the index as ``CREATE INDEX my_index ON table (x DESC)``
-
-.. versionadded:: 0.8
-
-.. seealso::
-
-    :ref:`schema_indexes_functional`
-
-Compatibility Levels
---------------------
-MSSQL supports the notion of setting compatibility levels at the
-database level. This allows, for instance, to run a database that
-is compatible with SQL2000 while running on a SQL2005 database
-server. ``server_version_info`` will always return the database
-server version information (in this case SQL2005) and not the
-compatibility level information. Because of this, if running under
-a backwards compatibility mode SQAlchemy may attempt to use T-SQL
-statements that are unable to be parsed by the database server.
-
-Triggers
---------
-
-SQLAlchemy by default uses OUTPUT INSERTED to get at newly
-generated primary key values via IDENTITY columns or other
-server side defaults.   MS-SQL does not
-allow the usage of OUTPUT INSERTED on tables that have triggers.
-To disable the usage of OUTPUT INSERTED on a per-table basis,
-specify ``implicit_returning=False`` for each :class:`.Table`
-which has triggers::
-
-    Table('mytable', metadata,
-        Column('id', Integer, primary_key=True),
-        # ...,
-        implicit_returning=False
-    )
-
-Declarative form::
-
-    class MyClass(Base):
-        # ...
-        __table_args__ = {'implicit_returning':False}
-
-
-This option can also be specified engine-wide using the
-``implicit_returning=False`` argument on :func:`.create_engine`.
-
-Enabling Snapshot Isolation
----------------------------
-
-Not necessarily specific to SQLAlchemy, SQL Server has a default transaction
-isolation mode that locks entire tables, and causes even mildly concurrent
-applications to have long held locks and frequent deadlocks.
-Enabling snapshot isolation for the database as a whole is recommended
-for modern levels of concurrency support.  This is accomplished via the
-following ALTER DATABASE commands executed at the SQL prompt::
-
-    ALTER DATABASE MyDatabase SET ALLOW_SNAPSHOT_ISOLATION ON
-
-    ALTER DATABASE MyDatabase SET READ_COMMITTED_SNAPSHOT ON
-
-Background on SQL Server snapshot isolation is available at
-http://msdn.microsoft.com/en-us/library/ms175095.aspx.
-
-Known Issues
-------------
-
-* No support for more than one ``IDENTITY`` column per table
-* reflection of indexes does not work with versions older than
-  SQL Server 2005

-
-Execution Modes
----------------
-
-mxODBC features two styles of statement execution, using the
-``cursor.execute()`` and ``cursor.executedirect()`` methods (the second being
-an extension to the DBAPI specification). The former makes use of a particular
-API call specific to the SQL Server Native Client ODBC driver known
-SQLDescribeParam, while the latter does not.
-
-mxODBC apparently only makes repeated use of a single prepared statement
-when SQLDescribeParam is used. The advantage to prepared statement reuse is
-one of performance. The disadvantage is that SQLDescribeParam has a limited
-set of scenarios in which bind parameters are understood, including that they
-cannot be placed within the argument lists of function calls, anywhere outside
-the FROM, or even within subqueries within the FROM clause - making the usage
-of bind parameters within SELECT statements impossible for all but the most
-simplistic statements.
-
-For this reason, the mxODBC dialect uses the "native" mode by default only for
-INSERT, UPDATE, and DELETE statements, and uses the escaped string mode for
-all other statements.
-
-This behavior can be controlled via
-:meth:`~sqlalchemy.sql.expression.Executable.execution_options` using the
-``native_odbc_execute`` flag with a value of ``True`` or ``False``, where a
-value of ``True`` will unconditionally use native bind parameters and a value
-of ``False`` will unconditionally use string-escaped parameters.

-    :url: http://pypi.python.org/pypi/pyodbc/
-
-Additional Connection Examples
--------------------------------
-
-Examples of pyodbc connection string URLs:
-
-* ``mssql+pyodbc://mydsn`` - connects using the specified DSN named ``mydsn``.
-  The connection string that is created will appear like::
-
-    dsn=mydsn;Trusted_Connection=Yes
-
-* ``mssql+pyodbc://user:pass@mydsn`` - connects using the DSN named
-  ``mydsn`` passing in the ``UID`` and ``PWD`` information. The
-  connection string that is created will appear like::
-
-    dsn=mydsn;UID=user;PWD=pass
-
-* ``mssql+pyodbc://user:pass@mydsn/?LANGUAGE=us_english`` - connects
-  using the DSN named ``mydsn`` passing in the ``UID`` and ``PWD``
-  information, plus the additional connection configuration option
-  ``LANGUAGE``. The connection string that is created will appear
-  like::
-
-    dsn=mydsn;UID=user;PWD=pass;LANGUAGE=us_english
-
-* ``mssql+pyodbc://user:pass@host/db`` - connects using a connection
-  that would appear like::
-
-    DRIVER={SQL Server};Server=host;Database=db;UID=user;PWD=pass
-
-* ``mssql+pyodbc://user:pass@host:123/db`` - connects using a connection
-  string which includes the port
-  information using the comma syntax. This will create the following
-  connection string::
-
-    DRIVER={SQL Server};Server=host,123;Database=db;UID=user;PWD=pass
-
-* ``mssql+pyodbc://user:pass@host/db?port=123`` - connects using a connection
-  string that includes the port
-  information as a separate ``port`` keyword. This will create the
-  following connection string::
-
-    DRIVER={SQL Server};Server=host;Database=db;UID=user;PWD=pass;port=123
-
-* ``mssql+pyodbc://user:pass@host/db?driver=MyDriver`` - connects using a connection
-  string that includes a custom
-  ODBC driver name.  This will create the following connection string::
-
-    DRIVER={MyDriver};Server=host;Database=db;UID=user;PWD=pass
-
-If you require a connection string that is outside the options
-presented above, use the ``odbc_connect`` keyword to pass in a
-urlencoded connection string. What gets passed in will be urldecoded
-and passed directly.
-
-For example::
-
-    mssql+pyodbc:///?odbc_connect=dsn%3Dmydsn%3BDatabase%3Ddb
-
-would create the following connection string::
-
-    dsn=mydsn;Database=db
-
-Encoding your connection string can be easily accomplished through
-the python shell. For example::
-
-    >>> import urllib
-    >>> urllib.quote_plus('dsn=mydsn;Database=db')
-    'dsn%3Dmydsn%3BDatabase%3Ddb'
-
-Unicode Binds
--------------
-
-The current state of PyODBC on a unix backend with FreeTDS and/or
-EasySoft is poor regarding unicode; different OS platforms and versions of UnixODBC
-versus IODBC versus FreeTDS/EasySoft versus PyODBC itself dramatically
-alter how strings are received.  The PyODBC dialect attempts to use all the information
-it knows to determine whether or not a Python unicode literal can be
-passed directly to the PyODBC driver or not; while SQLAlchemy can encode
-these to bytestrings first, some users have reported that PyODBC mis-handles
-bytestrings for certain encodings and requires a Python unicode object,
-while the author has observed widespread cases where a Python unicode
-is completely misinterpreted by PyODBC, particularly when dealing with
-the information schema tables used in table reflection, and the value
-must first be encoded to a bytestring.
-
-It is for this reason that whether or not unicode literals for bound
-parameters be sent to PyODBC can be controlled using the
-``supports_unicode_binds`` parameter to ``create_engine()``.  When
-left at its default of ``None``, the PyODBC dialect will use its
-best guess as to whether or not the driver deals with unicode literals
-well.  When ``False``, unicode literals will be encoded first, and when
-``True`` unicode literals will be passed straight through.  This is an interim
-flag that hopefully should not be needed when the unicode situation stabilizes
-for unix + PyODBC.

-    :name: MySQL
-
-Supported Versions and Features
--------------------------------
-
-SQLAlchemy supports MySQL starting with version 4.1 through modern releases.
-However, no heroic measures are taken to work around major missing
-SQL features - if your server version does not support sub-selects, for
-example, they won't work in SQLAlchemy either.
-
-See the official MySQL documentation for detailed information about features
-supported in any given server release.
-
-.. _mysql_connection_timeouts:
-
-Connection Timeouts
--------------------
-
-MySQL features an automatic connection close behavior, for connections that have
-been idle for eight hours or more.   To circumvent having this issue, use the
-``pool_recycle`` option which controls the maximum age of any connection::
-
-    engine = create_engine('mysql+mysqldb://...', pool_recycle=3600)
-
-.. _mysql_storage_engines:
-
-CREATE TABLE arguments including Storage Engines
-------------------------------------------------
-
-MySQL's CREATE TABLE syntax includes a wide array of special options,
-including ``ENGINE``, ``CHARSET``, ``MAX_ROWS``, ``ROW_FORMAT``, ``INSERT_METHOD``, and many more.
-To accommodate the rendering of these arguments, specify the form
-``mysql_argument_name="value"``.  For example, to specify a table with
-``ENGINE`` of ``InnoDB``, ``CHARSET`` of ``utf8``, and ``KEY_BLOCK_SIZE`` of ``1024``::
-
-  Table('mytable', metadata,
-        Column('data', String(32)),
-        mysql_engine='InnoDB',
-        mysql_charset='utf8',
-        mysql_key_block_size="1024"
-       )
-
-The MySQL dialect will normally transfer any keyword specified as ``mysql_keyword_name``
-to be rendered as ``KEYWORD_NAME`` in the ``CREATE TABLE`` statement.  A handful
-of these names will render with a space instead of an underscore; to support this,
-the MySQL dialect has awareness of these particular names, which include
-``DATA DIRECTORY`` (e.g. ``mysql_data_directory``), ``CHARACTER SET`` (e.g.
-``mysql_character_set``) and ``INDEX DIRECTORY`` (e.g. ``mysql_index_directory``).
-
-The most common argument is ``mysql_engine``, which refers to the storage engine
-for the table.  Historically, MySQL server installations would default
-to ``MyISAM`` for this value, although newer versions may be defaulting
-to ``InnoDB``.  The ``InnoDB`` engine is typically preferred for its support
-of transactions and foreign keys.
-
-A :class:`.Table` that is created in a MySQL database with a storage engine
-of ``MyISAM`` will be essentially non-transactional, meaning any INSERT/UPDATE/DELETE
-statement referring to this table will be invoked as autocommit.   It also will have no
-support for foreign key constraints; while the ``CREATE TABLE`` statement
-accepts foreign key options, when using the ``MyISAM`` storage engine these
-arguments are discarded.  Reflecting such a table will also produce no
-foreign key constraint information.
-
-For fully atomic transactions as well as support for foreign key
-constraints, all participating ``CREATE TABLE`` statements must specify a
-transactional engine, which in the vast majority of cases is ``InnoDB``.
-
-.. seealso::
-
-    `The InnoDB Storage Engine
-    <http://dev.mysql.com/doc/refman/5.0/en/innodb-storage-engine.html>`_ -
-    on the MySQL website.
-
-Case Sensitivity and Table Reflection
--------------------------------------
-
-MySQL has inconsistent support for case-sensitive identifier
-names, basing support on specific details of the underlying
-operating system. However, it has been observed that no matter
-what case sensitivity behavior is present, the names of tables in
-foreign key declarations are *always* received from the database
-as all-lower case, making it impossible to accurately reflect a
-schema where inter-related tables use mixed-case identifier names.
-
-Therefore it is strongly advised that table names be declared as
-all lower case both within SQLAlchemy as well as on the MySQL
-database itself, especially if database reflection features are
-to be used.
-
-Transaction Isolation Level
----------------------------
-
-:func:`.create_engine` accepts an ``isolation_level``
-parameter which results in the command ``SET SESSION
-TRANSACTION ISOLATION LEVEL <level>`` being invoked for
-every new connection. Valid values for this parameter are
-``READ COMMITTED``, ``READ UNCOMMITTED``,
-``REPEATABLE READ``, and ``SERIALIZABLE``::
-
-    engine = create_engine(
-                    "mysql://scott:tiger@localhost/test",
-                    isolation_level="READ UNCOMMITTED"
-                )
-
-.. versionadded:: 0.7.6
-
-AUTO_INCREMENT Behavior
------------------------
-
-When creating tables, SQLAlchemy will automatically set ``AUTO_INCREMENT`` on
-the first :class:`.Integer` primary key column which is not marked as a foreign key::
-
-  >>> t = Table('mytable', metadata,
-  ...   Column('mytable_id', Integer, primary_key=True)
-  ... )
-  >>> t.create()
-  CREATE TABLE mytable (
-          id INTEGER NOT NULL AUTO_INCREMENT,
-          PRIMARY KEY (id)
-  )
-
-You can disable this behavior by passing ``False`` to the :paramref:`~.Column.autoincrement`
-argument of :class:`.Column`.  This flag can also be used to enable
-auto-increment on a secondary column in a multi-column key for some storage
-engines::
-
-  Table('mytable', metadata,
-        Column('gid', Integer, primary_key=True, autoincrement=False),
-        Column('id', Integer, primary_key=True)
-       )
-
-Ansi Quoting Style
-------------------
-
-MySQL features two varieties of identifier "quoting style", one using
-backticks and the other using quotes, e.g. ```some_identifier```  vs.
-``"some_identifier"``.   All MySQL dialects detect which version
-is in use by checking the value of ``sql_mode`` when a connection is first
-established with a particular :class:`.Engine`.  This quoting style comes
-into play when rendering table and column names as well as when reflecting
-existing database structures.  The detection is entirely automatic and
-no special configuration is needed to use either quoting style.
-
-.. versionchanged:: 0.6 detection of ANSI quoting style is entirely automatic,
-   there's no longer any end-user ``create_engine()`` options in this regard.
-
-MySQL SQL Extensions
---------------------
-
-Many of the MySQL SQL extensions are handled through SQLAlchemy's generic
-function and operator support::
-
-  table.select(table.c.password==func.md5('plaintext'))
-  table.select(table.c.username.op('regexp')('^[a-d]'))
-
-And of course any valid MySQL statement can be executed as a string as well.
-
-Some limited direct support for MySQL extensions to SQL is currently
-available.
-
-* SELECT pragma::
-
-    select(..., prefixes=['HIGH_PRIORITY', 'SQL_SMALL_RESULT'])
-
-* UPDATE with LIMIT::
-
-    update(..., mysql_limit=10)
-
-rowcount Support
-----------------
-
-SQLAlchemy standardizes the DBAPI ``cursor.rowcount`` attribute to be the
-usual definition of "number of rows matched by an UPDATE or DELETE" statement.
-This is in contradiction to the default setting on most MySQL DBAPI drivers,
-which is "number of rows actually modified/deleted".  For this reason, the
-SQLAlchemy MySQL dialects always set the ``constants.CLIENT.FOUND_ROWS`` flag,
-or whatever is equivalent for the DBAPI in use, on connect, unless the flag value
-is overridden using DBAPI-specific options
-(such as ``client_flag`` for the MySQL-Python driver, ``found_rows`` for the
-OurSQL driver).
-
-See also:
-
-:attr:`.ResultProxy.rowcount`
-
-
-CAST Support
-------------
-
-MySQL documents the CAST operator as available in version 4.0.2.  When using the
-SQLAlchemy :func:`.cast` function, SQLAlchemy
-will not render the CAST token on MySQL before this version, based on server version
-detection, instead rendering the internal expression directly.
-
-CAST may still not be desirable on an early MySQL version post-4.0.2, as it didn't
-add all datatype support until 4.1.1.   If your application falls into this
-narrow area, the behavior of CAST can be controlled using the
-:ref:`sqlalchemy.ext.compiler_toplevel` system, as per the recipe below::
-
-    from sqlalchemy.sql.expression import Cast
-    from sqlalchemy.ext.compiler import compiles
-
-    @compiles(Cast, 'mysql')
-    def _check_mysql_version(element, compiler, **kw):
-        if compiler.dialect.server_version_info < (4, 1, 0):
-            return compiler.process(element.clause, **kw)
-        else:
-            return compiler.visit_cast(element, **kw)
-
-The above function, which only needs to be declared once
-within an application, overrides the compilation of the
-:func:`.cast` construct to check for version 4.1.0 before
-fully rendering CAST; else the internal element of the
-construct is rendered directly.
-
-
-.. _mysql_indexes:
-
-MySQL Specific Index Options
-----------------------------
-
-MySQL-specific extensions to the :class:`.Index` construct are available.
-
-Index Length
-~~~~~~~~~~~~~
-
-MySQL provides an option to create index entries with a certain length, where
-"length" refers to the number of characters or bytes in each value which will
-become part of the index. SQLAlchemy provides this feature via the
-``mysql_length`` parameter::
-
-    Index('my_index', my_table.c.data, mysql_length=10)
-
-    Index('a_b_idx', my_table.c.a, my_table.c.b, mysql_length={'a': 4, 'b': 9})
-
-Prefix lengths are given in characters for nonbinary string types and in bytes
-for binary string types. The value passed to the keyword argument *must* be
-either an integer (and, thus, specify the same prefix length value for all
-columns of the index) or a dict in which keys are column names and values are
-prefix length values for corresponding columns. MySQL only allows a length for
-a column of an index if it is for a CHAR, VARCHAR, TEXT, BINARY, VARBINARY and
-BLOB.
-
-.. versionadded:: 0.8.2 ``mysql_length`` may now be specified as a dictionary
-   for use with composite indexes.
-
-Index Types
-~~~~~~~~~~~~~
-
-Some MySQL storage engines permit you to specify an index type when creating
-an index or primary key constraint. SQLAlchemy provides this feature via the
-``mysql_using`` parameter on :class:`.Index`::
-
-    Index('my_index', my_table.c.data, mysql_using='hash')
-
-As well as the ``mysql_using`` parameter on :class:`.PrimaryKeyConstraint`::
-
-    PrimaryKeyConstraint("data", mysql_using='hash')
-
-The value passed to the keyword argument will be simply passed through to the
-underlying CREATE INDEX or PRIMARY KEY clause, so it *must* be a valid index
-type for your MySQL storage engine.
-
-More information can be found at:
-
-http://dev.mysql.com/doc/refman/5.0/en/create-index.html
-
-http://dev.mysql.com/doc/refman/5.0/en/create-table.html
-
-.. _mysql_foreign_keys:
-
-MySQL Foreign Keys
-------------------
-
-MySQL's behavior regarding foreign keys has some important caveats.
-
-Foreign Key Arguments to Avoid
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-MySQL does not support the foreign key arguments "DEFERRABLE", "INITIALLY",
-or "MATCH".  Using the ``deferrable`` or ``initially`` keyword argument with
-:class:`.ForeignKeyConstraint` or :class:`.ForeignKey` will have the effect of these keywords being
-rendered in a DDL expression, which will then raise an error on MySQL.
-In order to use these keywords on a foreign key while having them ignored
-on a MySQL backend, use a custom compile rule::
-
-    from sqlalchemy.ext.compiler import compiles
-    from sqlalchemy.schema import ForeignKeyConstraint
-
-    @compiles(ForeignKeyConstraint, "mysql")
-    def process(element, compiler, **kw):
-        element.deferrable = element.initially = None
-        return compiler.visit_foreign_key_constraint(element, **kw)
-
-.. versionchanged:: 0.9.0 - the MySQL backend no longer silently ignores
-   the ``deferrable`` or ``initially`` keyword arguments of :class:`.ForeignKeyConstraint`
-   and :class:`.ForeignKey`.
-
-The "MATCH" keyword is in fact more insidious, and is explicitly disallowed
-by SQLAlchemy in conjunction with the MySQL backend.  This argument is silently
-ignored by MySQL, but in addition has the effect of ON UPDATE and ON DELETE options
-also being ignored by the backend.   Therefore MATCH should never be used with the
-MySQL backend; as is the case with DEFERRABLE and INITIALLY, custom compilation
-rules can be used to correct a MySQL ForeignKeyConstraint at DDL definition time.
-
-.. versionadded:: 0.9.0 - the MySQL backend will raise a :class:`.CompileError`
-   when the ``match`` keyword is used with :class:`.ForeignKeyConstraint`
-   or :class:`.ForeignKey`.
-
-Reflection of Foreign Key Constraints
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Not all MySQL storage engines support foreign keys.  When using the
-very common ``MyISAM`` MySQL storage engine, the information loaded by table
-reflection will not include foreign keys.  For these tables, you may supply a
-:class:`~sqlalchemy.ForeignKeyConstraint` at reflection time::
-
-  Table('mytable', metadata,
-        ForeignKeyConstraint(['other_id'], ['othertable.other_id']),
-        autoload=True
-       )
-
-.. seealso::

-
-Unicode
--------
-
-MySQLdb requires a "charset" parameter to be passed in order for it
-to handle non-ASCII characters correctly.   When this parameter is passed,
-MySQLdb will also implicitly set the "use_unicode" flag to true, which means
-that it will return Python unicode objects instead of bytestrings.
-However, SQLAlchemy's decode process, when C extensions are enabled,
-is orders of magnitude faster than that of MySQLdb as it does not call into
-Python functions to do so.  Therefore, the **recommended URL to use for
-unicode** will include both charset and use_unicode=0::
-
-    create_engine("mysql+mysqldb://user:pass@host/dbname?charset=utf8&use_unicode=0")
-
-As of this writing, MySQLdb only runs on Python 2.   It is not known how
-MySQLdb behaves on Python 3 as far as unicode decoding.
-
-
-Known Issues
--------------
-
-MySQL-python version 1.2.2 has a serious memory leak related
-to unicode conversion, a feature which is disabled via ``use_unicode=0``.
-It is strongly advised to use the latest version of MySQL-Python.

-Unicode
--------
-
-oursql defaults to using ``utf8`` as the connection charset, but other
-encodings may be used instead. Like the MySQL-Python driver, unicode support
-can be completely disabled::
-
-  # oursql sets the connection charset to utf8 automatically; all strings come
-  # back as utf8 str
-  create_engine('mysql+oursql:///mydb?use_unicode=0')
-
-To not automatically use ``utf8`` and instead use whatever the connection
-defaults to, there is a separate parameter::
-
-  # use the default connection charset; all strings come back as unicode
-  create_engine('mysql+oursql:///mydb?default_charset=1')
-
-  # use latin1 as the connection charset; all strings come back as unicode

-.. dialect:: oracle
-    :name: Oracle
-
-    Oracle version 8 through current (11g at the time of this writing) are supported.
-
-Connect Arguments
------------------
-
-The dialect supports several :func:`~sqlalchemy.create_engine()` arguments which
-affect the behavior of the dialect regardless of driver in use.
-
-* ``use_ansi`` - Use ANSI JOIN constructs (see the section on Oracle 8).  Defaults
-  to ``True``.  If ``False``, Oracle-8 compatible constructs are used for joins.
-
-* ``optimize_limits`` - defaults to ``False``. see the section on LIMIT/OFFSET.
-
-* ``use_binds_for_limits`` - defaults to ``True``.  see the section on LIMIT/OFFSET.
-
-Auto Increment Behavior
------------------------
-
-SQLAlchemy Table objects which include integer primary keys are usually assumed to have
-"autoincrementing" behavior, meaning they can generate their own primary key values upon
-INSERT.  Since Oracle has no "autoincrement" feature, SQLAlchemy relies upon sequences
-to produce these values.   With the Oracle dialect, *a sequence must always be explicitly
-specified to enable autoincrement*.  This is divergent with the majority of documentation
-examples which assume the usage of an autoincrement-capable database.   To specify sequences,
-use the sqlalchemy.schema.Sequence object which is passed to a Column construct::
-
-  t = Table('mytable', metadata,
-        Column('id', Integer, Sequence('id_seq'), primary_key=True),
-        Column(...), ...
-  )
-
-This step is also required when using table reflection, i.e. autoload=True::
-
-  t = Table('mytable', metadata,
-        Column('id', Integer, Sequence('id_seq'), primary_key=True),
-        autoload=True
-  )
-
-Identifier Casing
------------------
-
-In Oracle, the data dictionary represents all case insensitive identifier names
-using UPPERCASE text.   SQLAlchemy on the other hand considers an all-lower case identifier
-name to be case insensitive.   The Oracle dialect converts all case insensitive identifiers
-to and from those two formats during schema level communication, such as reflection of
-tables and indexes.   Using an UPPERCASE name on the SQLAlchemy side indicates a
-case sensitive identifier, and SQLAlchemy will quote the name - this will cause mismatches
-against data dictionary data received from Oracle, so unless identifier names have been
-truly created as case sensitive (i.e. using quoted names), all lowercase names should be
-used on the SQLAlchemy side.
-
-
-LIMIT/OFFSET Support
---------------------
-
-Oracle has no support for the LIMIT or OFFSET keywords.  SQLAlchemy uses
-a wrapped subquery approach in conjunction with ROWNUM.  The exact methodology
-is taken from
-http://www.oracle.com/technology/oramag/oracle/06-sep/o56asktom.html .
-
-There are two options which affect its behavior:
-
-* the "FIRST ROWS()" optimization keyword is not used by default.  To enable the usage of this
-  optimization directive, specify ``optimize_limits=True`` to :func:`.create_engine`.
-* the values passed for the limit/offset are sent as bound parameters.   Some users have observed
-  that Oracle produces a poor query plan when the values are sent as binds and not
-  rendered literally.   To render the limit/offset values literally within the SQL
-  statement, specify ``use_binds_for_limits=False`` to :func:`.create_engine`.
-
-Some users have reported better performance when the entirely different approach of a
-window query is used, i.e. ROW_NUMBER() OVER (ORDER BY), to provide LIMIT/OFFSET (note
-that the majority of users don't observe this).  To suit this case the
-method used for LIMIT/OFFSET can be replaced entirely.  See the recipe at
-http://www.sqlalchemy.org/trac/wiki/UsageRecipes/WindowFunctionsByDefault
-which installs a select compiler that overrides the generation of limit/offset with
-a window function.
-
-.. _oracle_returning:
-
-RETURNING Support
------------------
-
-The Oracle database supports a limited form of RETURNING, in order to retrieve result
-sets of matched rows from INSERT, UPDATE and DELETE statements.  Oracle's
-RETURNING..INTO syntax only supports one row being returned, as it relies upon
-OUT parameters in order to function.  In addition, supported DBAPIs have further
-limitations (see :ref:`cx_oracle_returning`).
-
-SQLAlchemy's "implicit returning" feature, which employs RETURNING within an INSERT
-and sometimes an UPDATE statement in order to fetch newly generated primary key values
-and other SQL defaults and expressions, is normally enabled on the Oracle
-backend.  By default, "implicit returning" typically only fetches the value of a
-single ``nextval(some_seq)`` expression embedded into an INSERT in order to increment
-a sequence within an INSERT statement and get the value back at the same time.
-To disable this feature across the board, specify ``implicit_returning=False`` to
-:func:`.create_engine`::
-
-    engine = create_engine("oracle://scott:tiger@dsn", implicit_returning=False)
-
-Implicit returning can also be disabled on a table-by-table basis as a table option::
-
-    # Core Table
-    my_table = Table("my_table", metadata, ..., implicit_returning=False)
-
-
-    # declarative
-    class MyClass(Base):
-        __tablename__ = 'my_table'
-        __table_args__ = {"implicit_returning": False}
-
-.. seealso::
-
-    :ref:`cx_oracle_returning` - additional cx_oracle-specific restrictions on implicit returning.
-
-ON UPDATE CASCADE
------------------
-
-Oracle doesn't have native ON UPDATE CASCADE functionality.  A trigger based solution
-is available at http://asktom.oracle.com/tkyte/update_cascade/index.html .
-
-When using the SQLAlchemy ORM, the ORM has limited ability to manually issue
-cascading updates - specify ForeignKey objects using the
-"deferrable=True, initially='deferred'" keyword arguments,
-and specify "passive_updates=False" on each relationship().
-
-Oracle 8 Compatibility
-----------------------
-
-When Oracle 8 is detected, the dialect internally configures itself to the following
-behaviors:
-
-* the use_ansi flag is set to False.  This has the effect of converting all
-  JOIN phrases into the WHERE clause, and in the case of LEFT OUTER JOIN
-  makes use of Oracle's (+) operator.
-
-* the NVARCHAR2 and NCLOB datatypes are no longer generated as DDL when
-  the :class:`~sqlalchemy.types.Unicode` is used - VARCHAR2 and CLOB are issued
-  instead.   This because these types don't seem to work correctly on Oracle 8
-  even though they are available.  The :class:`~sqlalchemy.types.NVARCHAR`
-  and :class:`~sqlalchemy.dialects.oracle.NCLOB` types will always generate NVARCHAR2 and NCLOB.
-
-* the "native unicode" mode is disabled when using cx_oracle, i.e. SQLAlchemy
-  encodes all Python unicode objects to "string" before passing in as bind parameters.
-
-Synonym/DBLINK Reflection
--------------------------
-
-When using reflection with Table objects, the dialect can optionally search for tables
-indicated by synonyms, either in local or remote schemas or accessed over DBLINK,
-by passing the flag ``oracle_resolve_synonyms=True`` as a
-keyword argument to the :class:`.Table` construct::
-
-    some_table = Table('some_table', autoload=True,
-                                autoload_with=some_engine,
-                                oracle_resolve_synonyms=True)
-
-When this flag is set, the given name (such as ``some_table`` above) will
-be searched not just in the ``ALL_TABLES`` view, but also within the
-``ALL_SYNONYMS`` view to see if this name is actually a synonym to another name.
-If the synonym is located and refers to a DBLINK, the oracle dialect knows
-how to locate the table's information using DBLINK syntax (e.g. ``@dblink``).
-
-``oracle_resolve_synonyms`` is accepted wherever reflection arguments are
-accepted, including methods such as :meth:`.MetaData.reflect` and
-:meth:`.Inspector.get_columns`.
-
-If synonyms are not in use, this flag should be left disabled.
-
-DateTime Compatibility
-----------------------
-
-Oracle has no datatype known as ``DATETIME``, it instead has only ``DATE``,
-which can actually store a date and time value.  For this reason, the Oracle
-dialect provides a type :class:`.oracle.DATE` which is a subclass of
-:class:`.DateTime`.   This type has no special behavior, and is only
-present as a "marker" for this type; additionally, when a database column
-is reflected and the type is reported as ``DATE``, the time-supporting
-:class:`.oracle.DATE` type is used.
-
-.. versionchanged:: 0.9.4 Added :class:`.oracle.DATE` to subclass
-   :class:`.DateTime`.  This is a change as previous versions
-   would reflect a ``DATE`` column as :class:`.types.DATE`, which subclasses
-   :class:`.Date`.   The only significance here is for schemes that are
-   examining the type of column for use in special Python translations or
-   for migrating schemas to other database backends.

-    :name: cx-Oracle
-    :dbapi: cx_oracle
-    :connectstring: oracle+cx_oracle://user:pass@host:port/dbname[?key=value&key=value...]
-    :url: http://cx-oracle.sourceforge.net/
-
-Additional Connect Arguments
-----------------------------
-
-When connecting with ``dbname`` present, the host, port, and dbname tokens are
-converted to a TNS name using
-the cx_oracle ``makedsn()`` function.  Otherwise, the host token is taken
-directly as a TNS name.
-
-Additional arguments which may be specified either as query string arguments
-on the URL, or as keyword arguments to :func:`.create_engine()` are:
-
-* ``allow_twophase`` - enable two-phase transactions.  Defaults to ``True``.
-
-* ``arraysize`` - set the cx_oracle.arraysize value on cursors, defaulted
-  to 50.  This setting is significant with cx_Oracle as the contents of LOB
-  objects are only readable within a "live" row (e.g. within a batch of
-  50 rows).
-
-* ``auto_convert_lobs`` - defaults to True; See :ref:`cx_oracle_lob`.
-
-* ``auto_setinputsizes`` - the cx_oracle.setinputsizes() call is issued for
-  all bind parameters.  This is required for LOB datatypes but can be
-  disabled to reduce overhead.  Defaults to ``True``.  Specific types
-  can be excluded from this process using the ``exclude_setinputsizes``
-  parameter.
-
-* ``coerce_to_unicode`` - see :ref:`cx_oracle_unicode` for detail.
-
-* ``coerce_to_decimal`` - see :ref:`cx_oracle_numeric` for detail.
-
-* ``exclude_setinputsizes`` - a tuple or list of string DBAPI type names to
-  be excluded from the "auto setinputsizes" feature.  The type names here
-  must match DBAPI types that are found in the "cx_Oracle" module namespace,
-  such as cx_Oracle.UNICODE, cx_Oracle.NCLOB, etc.   Defaults to
-  ``(STRING, UNICODE)``.
-
-  .. versionadded:: 0.8 specific DBAPI types can be excluded from the
-     auto_setinputsizes feature via the exclude_setinputsizes attribute.
-
-* ``mode`` - This is given the string value of SYSDBA or SYSOPER, or alternatively
-  an integer value.  This value is only available as a URL query string
-  argument.
-
-* ``threaded`` - enable multithreaded access to cx_oracle connections.  Defaults
-  to ``True``.  Note that this is the opposite default of the cx_Oracle DBAPI
-  itself.
-
-.. _cx_oracle_unicode:
-
-Unicode
--------
-
-The cx_Oracle DBAPI as of version 5 fully supports unicode, and has the ability
-to return string results as Python unicode objects natively.
-
-When used in Python 3, cx_Oracle returns all strings as Python unicode objects
-(that is, plain ``str`` in Python 3).  In Python 2, it will return as Python
-unicode those column values that are of type ``NVARCHAR`` or ``NCLOB``.  For
-column values that are of type ``VARCHAR`` or other non-unicode string types,
-it will return values as Python strings (e.g. bytestrings).
-
-The cx_Oracle SQLAlchemy dialect presents two different options for the use case of
-returning ``VARCHAR`` column values as Python unicode objects under Python 2:
-
-* the cx_Oracle DBAPI has the ability to coerce all string results to Python
-  unicode objects unconditionally using output type handlers.  This has
-  the advantage that the unicode conversion is global to all statements
-  at the cx_Oracle driver level, meaning it works with raw textual SQL
-  statements that have no typing information associated.  However, this system
-  has been observed to incur signfiicant performance overhead, not only because
-  it takes effect for all string values unconditionally, but also because cx_Oracle under
-  Python 2 seems to use a pure-Python function call in order to do the
-  decode operation, which under cPython can orders of magnitude slower
-  than doing it using C functions alone.
-
-* SQLAlchemy has unicode-decoding services built in, and when using SQLAlchemy's
-  C extensions, these functions do not use any Python function calls and
-  are very fast.  The disadvantage to this approach is that the unicode
-  conversion only takes effect for statements where the :class:`.Unicode` type
-  or :class:`.String` type with ``convert_unicode=True`` is explicitly
-  associated with the result column.  This is the case for any ORM or Core
-  query or SQL expression as well as for a :func:`.text` construct that specifies
-  output column types, so in the vast majority of cases this is not an issue.
-  However, when sending a completely raw string to :meth:`.Connection.execute`,
-  this typing information isn't present, unless the string is handled
-  within a :func:`.text` construct that adds typing information.
-
-As of version 0.9.2 of SQLAlchemy, the default approach is to use SQLAlchemy's
-typing system.  This keeps cx_Oracle's expensive Python 2 approach
-disabled unless the user explicitly wants it.  Under Python 3, SQLAlchemy detects
-that cx_Oracle is returning unicode objects natively and cx_Oracle's system
-is used.
-
-To re-enable cx_Oracle's output type handler under Python 2, the
-``coerce_to_unicode=True`` flag (new in 0.9.4) can be passed to
-:func:`.create_engine`::
-
-    engine = create_engine("oracle+cx_oracle://dsn", coerce_to_unicode=True)
-
-Alternatively, to run a pure string SQL statement and get ``VARCHAR`` results
-as Python unicode under Python 2 without using cx_Oracle's native handlers,
-the :func:`.text` feature can be used::
-
-    from sqlalchemy import text, Unicode
-    result = conn.execute(text("select username from user").columns(username=Unicode))
-
-.. versionchanged:: 0.9.2 cx_Oracle's outputtypehandlers are no longer used for
-   unicode results of non-unicode datatypes in Python 2, after they were identified as a major
-   performance bottleneck.  SQLAlchemy's own unicode facilities are used
-   instead.
-
-.. versionadded:: 0.9.4 Added the ``coerce_to_unicode`` flag, to re-enable
-   cx_Oracle's outputtypehandler and revert to pre-0.9.2 behavior.
-
-.. _cx_oracle_returning:
-
-RETURNING Support
------------------
-
-The cx_oracle DBAPI supports a limited subset of Oracle's already limited RETURNING support.
-Typically, results can only be guaranteed for at most one column being returned;
-this is the typical case when SQLAlchemy uses RETURNING to get just the value of a
-primary-key-associated sequence value.    Additional column expressions will
-cause problems in a non-determinative way, due to cx_oracle's lack of support for
-the OCI_DATA_AT_EXEC API which is required for more complex RETURNING scenarios.
-
-For this reason, stability may be enhanced by disabling RETURNING support completely;
-SQLAlchemy otherwise will use RETURNING to fetch newly sequence-generated
-primary keys.  As illustrated in :ref:`oracle_returning`::
-
-    engine = create_engine("oracle://scott:tiger@dsn", implicit_returning=False)
-
-.. seealso::
-
-    http://docs.oracle.com/cd/B10501_01/appdev.920/a96584/oci05bnd.htm#420693 - OCI documentation for RETURNING
-
-    http://sourceforge.net/mailarchive/message.php?msg_id=31338136 - cx_oracle developer commentary
-
-.. _cx_oracle_lob:
-
-LOB Objects
------------
-
-cx_oracle returns oracle LOBs using the cx_oracle.LOB object.  SQLAlchemy converts
-these to strings so that the interface of the Binary type is consistent with that of
-other backends, and so that the linkage to a live cursor is not needed in scenarios
-like result.fetchmany() and result.fetchall().   This means that by default, LOB
-objects are fully fetched unconditionally by SQLAlchemy, and the linkage to a live
-cursor is broken.
-
-To disable this processing, pass ``auto_convert_lobs=False`` to :func:`.create_engine()`.
-
-Two Phase Transaction Support
------------------------------
-
-Two Phase transactions are implemented using XA transactions, and are known
-to work in a rudimental fashion with recent versions of cx_Oracle
-as of SQLAlchemy 0.8.0b2, 0.7.10.   However, the mechanism is not yet
-considered to be robust and should still be regarded as experimental.
-
-In particular, the cx_Oracle DBAPI as recently as 5.1.2 has a bug regarding
-two phase which prevents
-a particular DBAPI connection from being consistently usable in both
-prepared transactions as well as traditional DBAPI usage patterns; therefore
-once a particular connection is used via :meth:`.Connection.begin_prepared`,
-all subsequent usages of the underlying DBAPI connection must be within
-the context of prepared transactions.
-
-The default behavior of :class:`.Engine` is to maintain a pool of DBAPI
-connections.  Therefore, due to the above glitch, a DBAPI connection that has
-been used in a two-phase operation, and is then returned to the pool, will
-not be usable in a non-two-phase context.   To avoid this situation,
-the application can make one of several choices:
-
-* Disable connection pooling using :class:`.NullPool`
-
-* Ensure that the particular :class:`.Engine` in use is only used
-  for two-phase operations.   A :class:`.Engine` bound to an ORM
-  :class:`.Session` which includes ``twophase=True`` will consistently
-  use the two-phase transaction style.
-
-* For ad-hoc two-phase operations without disabling pooling, the DBAPI
-  connection in use can be evicted from the connection pool using the
-  :meth:`.Connection.detach` method.
-
-.. versionchanged:: 0.8.0b2,0.7.10
-    Support for cx_oracle prepared transactions has been implemented
-    and tested.
-
-.. _cx_oracle_numeric:
-
-Precision Numerics
-------------------
-
-The SQLAlchemy dialect goes through a lot of steps to ensure
-that decimal numbers are sent and received with full accuracy.
-An "outputtypehandler" callable is associated with each
-cx_oracle connection object which detects numeric types and
-receives them as string values, instead of receiving a Python
-``float`` directly, which is then passed to the Python
-``Decimal`` constructor.  The :class:`.Numeric` and
-:class:`.Float` types under the cx_oracle dialect are aware of
-this behavior, and will coerce the ``Decimal`` to ``float`` if
-the ``asdecimal`` flag is ``False`` (default on :class:`.Float`,
-optional on :class:`.Numeric`).
-
-Because the handler coerces to ``Decimal`` in all cases first,
-the feature can detract significantly from performance.
-If precision numerics aren't required, the decimal handling
-can be disabled by passing the flag ``coerce_to_decimal=False``
-to :func:`.create_engine`::
-
-    engine = create_engine("oracle+cx_oracle://dsn", coerce_to_decimal=False)
-
-.. versionadded:: 0.7.6
-    Add the ``coerce_to_decimal`` flag.
-
-Another alternative to performance is to use the
-`cdecimal <http://pypi.python.org/pypi/cdecimal/>`_ library;
-see :class:`.Numeric` for additional notes.
-
-The handler attempts to use the "precision" and "scale"
-attributes of the result set column to best determine if
-subsequent incoming values should be received as ``Decimal`` as
-opposed to int (in which case no processing is added). There are
-several scenarios where OCI_ does not provide unambiguous data
-as to the numeric type, including some situations where
-individual rows may return a combination of floating point and
-integer values. Certain values for "precision" and "scale" have
-been observed to determine this scenario.  When it occurs, the
-outputtypehandler receives as string and then passes off to a
-processing function which detects, for each returned value, if a
-decimal point is present, and if so converts to ``Decimal``,
-otherwise to int.  The intention is that simple int-based
-statements like "SELECT my_seq.nextval() FROM DUAL" continue to
-return ints and not ``Decimal`` objects, and that any kind of
-floating point value is received as a string so that there is no
-floating point loss of precision.
-
-The "decimal point is present" logic itself is also sensitive to
-locale.  Under OCI_, this is controlled by the NLS_LANG
-environment variable. Upon first connection, the dialect runs a
-test to determine the current "decimal" character, which can be
-a comma "," for european locales. From that point forward the
-outputtypehandler uses that character to represent a decimal
-point. Note that cx_oracle 5.0.3 or greater is required
-when dealing with numerics with locale settings that don't use
-a period "." as the decimal character.
-
-.. versionchanged:: 0.6.6
-    The outputtypehandler supports the case where the locale uses a
-    comma "," character to represent a decimal point.

-.. dialect:: postgresql
-    :name: PostgreSQL
-
-
-Sequences/SERIAL
-----------------
-
-PostgreSQL supports sequences, and SQLAlchemy uses these as the default means
-of creating new primary key values for integer-based primary key columns. When
-creating tables, SQLAlchemy will issue the ``SERIAL`` datatype for
-integer-based primary key columns, which generates a sequence and server side
-default corresponding to the column.
-
-To specify a specific named sequence to be used for primary key generation,
-use the :func:`~sqlalchemy.schema.Sequence` construct::
-
-    Table('sometable', metadata,
-            Column('id', Integer, Sequence('some_id_seq'), primary_key=True)
-        )
-
-When SQLAlchemy issues a single INSERT statement, to fulfill the contract of
-having the "last insert identifier" available, a RETURNING clause is added to
-the INSERT statement which specifies the primary key columns should be
-returned after the statement completes. The RETURNING functionality only takes
-place if Postgresql 8.2 or later is in use. As a fallback approach, the
-sequence, whether specified explicitly or implicitly via ``SERIAL``, is
-executed independently beforehand, the returned value to be used in the
-subsequent insert. Note that when an
-:func:`~sqlalchemy.sql.expression.insert()` construct is executed using
-"executemany" semantics, the "last inserted identifier" functionality does not
-apply; no RETURNING clause is emitted nor is the sequence pre-executed in this
-case.
-
-To force the usage of RETURNING by default off, specify the flag
-``implicit_returning=False`` to :func:`.create_engine`.
-
-.. _postgresql_isolation_level:
-
-Transaction Isolation Level
----------------------------
-
-All Postgresql dialects support setting of transaction isolation level
-both via a dialect-specific parameter ``isolation_level``
-accepted by :func:`.create_engine`,
-as well as the ``isolation_level`` argument as passed to :meth:`.Connection.execution_options`.
-When using a non-psycopg2 dialect, this feature works by issuing the
-command ``SET SESSION CHARACTERISTICS AS TRANSACTION ISOLATION LEVEL
-<level>`` for each new connection.
-
-To set isolation level using :func:`.create_engine`::
-
-    engine = create_engine(
-                    "postgresql+pg8000://scott:tiger@localhost/test",
-                    isolation_level="READ UNCOMMITTED"
-                )
-
-To set using per-connection execution options::
-
-    connection = engine.connect()
-    connection = connection.execution_options(isolation_level="READ COMMITTED")
-
-Valid values for ``isolation_level`` include:
-
-* ``READ COMMITTED``
-* ``READ UNCOMMITTED``
-* ``REPEATABLE READ``
-* ``SERIALIZABLE``
-
-The :mod:`~sqlalchemy.dialects.postgresql.psycopg2` dialect also offers the special level ``AUTOCOMMIT``.  See
-:ref:`psycopg2_isolation_level` for details.
-
-.. _postgresql_schema_reflection:
-
-Remote-Schema Table Introspection and Postgresql search_path
-------------------------------------------------------------
-
-The Postgresql dialect can reflect tables from any schema.  The
-:paramref:`.Table.schema` argument, or alternatively the
-:paramref:`.MetaData.reflect.schema` argument determines which schema will
-be searched for the table or tables.   The reflected :class:`.Table` objects
-will in all cases retain this ``.schema`` attribute as was specified.  However,
-with regards to tables which these :class:`.Table` objects refer to via
-foreign key constraint, a decision must be made as to how the ``.schema``
-is represented in those remote tables, in the case where that remote
-schema name is also a member of the current
-`Postgresql search path <http://www.postgresql.org/docs/9.0/static/ddl-schemas.html#DDL-SCHEMAS-PATH>`_.
-
-By default, the Postgresql dialect mimics the behavior encouraged by
-Postgresql's own ``pg_get_constraintdef()`` builtin procedure.  This function
-returns a sample definition for a particular foreign key constraint,
-omitting the referenced schema name from that definition when the name is
-also in the Postgresql schema search path.  The interaction below
-illustrates this behavior::
-
-    test=> CREATE TABLE test_schema.referred(id INTEGER PRIMARY KEY);
-    CREATE TABLE
-    test=> CREATE TABLE referring(
-    test(>         id INTEGER PRIMARY KEY,
-    test(>         referred_id INTEGER REFERENCES test_schema.referred(id));
-    CREATE TABLE
-    test=> SET search_path TO public, test_schema;
-    test=> SELECT pg_catalog.pg_get_constraintdef(r.oid, true) FROM
-    test-> pg_catalog.pg_class c JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
-    test-> JOIN pg_catalog.pg_constraint r  ON c.oid = r.conrelid
-    test-> WHERE c.relname='referring' AND r.contype = 'f'
-    test-> ;
-                   pg_get_constraintdef
-    ---------------------------------------------------
-     FOREIGN KEY (referred_id) REFERENCES referred(id)
-    (1 row)
-
-Above, we created a table ``referred`` as a member of the remote schema ``test_schema``, however
-when we added ``test_schema`` to the PG ``search_path`` and then asked ``pg_get_constraintdef()``
-for the ``FOREIGN KEY`` syntax, ``test_schema`` was not included in the
-output of the function.
-
-On the other hand, if we set the search path back to the typical default
-of ``public``::
-
-    test=> SET search_path TO public;
-    SET
-
-The same query against ``pg_get_constraintdef()`` now returns the fully
-schema-qualified name for us::
-
-    test=> SELECT pg_catalog.pg_get_constraintdef(r.oid, true) FROM
-    test-> pg_catalog.pg_class c JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
-    test-> JOIN pg_catalog.pg_constraint r  ON c.oid = r.conrelid
-    test-> WHERE c.relname='referring' AND r.contype = 'f';
-                         pg_get_constraintdef
-    ---------------------------------------------------------------
-     FOREIGN KEY (referred_id) REFERENCES test_schema.referred(id)
-    (1 row)
-
-SQLAlchemy will by default use the return value of ``pg_get_constraintdef()``
-in order to determine the remote schema name.  That is, if our ``search_path``
-were set to include ``test_schema``, and we invoked a table
-reflection process as follows::
-
-    >>> from sqlalchemy import Table, MetaData, create_engine
-    >>> engine = create_engine("postgresql://scott:tiger@localhost/test")
-    >>> with engine.connect() as conn:
-    ...     conn.execute("SET search_path TO test_schema, public")
-    ...     meta = MetaData()
-    ...     referring = Table('referring', meta, autoload=True, autoload_with=conn)
-    ...
-    <sqlalchemy.engine.result.ResultProxy object at 0x101612ed0>
-
-The above process would deliver to the :attr:`.MetaData.tables` collection
-``referred`` table named **without** the schema::
-
-    >>> meta.tables['referred'].schema is None
-    True
-
-To alter the behavior of reflection such that the referred schema is maintained
-regardless of the ``search_path`` setting, use the ``postgresql_ignore_search_path``
-option, which can be specified as a dialect-specific argument to both
-:class:`.Table` as well as :meth:`.MetaData.reflect`::
-
-    >>> with engine.connect() as conn:
-    ...     conn.execute("SET search_path TO test_schema, public")
-    ...     meta = MetaData()
-    ...     referring = Table('referring', meta, autoload=True, autoload_with=conn,
-    ...                     postgresql_ignore_search_path=True)
-    ...
-    <sqlalchemy.engine.result.ResultProxy object at 0x1016126d0>
-
-We will now have ``test_schema.referred`` stored as schema-qualified::
-
-    >>> meta.tables['test_schema.referred'].schema
-    'test_schema'
-
-.. sidebar:: Best Practices for Postgresql Schema reflection
-
-    The description of Postgresql schema reflection behavior is complex, and is
-    the product of many years of dealing with widely varied use cases and user preferences.
-    But in fact, there's no need to understand any of it if you just stick to the simplest
-    use pattern: leave the ``search_path`` set to its default of ``public`` only, never refer
-    to the name ``public`` as an explicit schema name otherwise, and
-    refer to all other schema names explicitly when building
-    up a :class:`.Table` object.  The options described here are only for those users
-    who can't, or prefer not to, stay within these guidelines.
-
-Note that **in all cases**, the "default" schema is always reflected as ``None``.
-The "default" schema on Postgresql is that which is returned by the
-Postgresql ``current_schema()`` function.  On a typical Postgresql installation,
-this is the name ``public``.  So a table that refers to another which is
-in the ``public`` (i.e. default) schema will always have the ``.schema`` attribute
-set to ``None``.
-
-.. versionadded:: 0.9.2 Added the ``postgresql_ignore_search_path``
-   dialect-level option accepted by :class:`.Table` and :meth:`.MetaData.reflect`.
-
-
-.. seealso::
-
-        `The Schema Search Path <http://www.postgresql.org/docs/9.0/static/ddl-schemas.html#DDL-SCHEMAS-PATH>`_ - on the Postgresql website.
-
-INSERT/UPDATE...RETURNING
--------------------------
-
-The dialect supports PG 8.2's ``INSERT..RETURNING``, ``UPDATE..RETURNING`` and
-``DELETE..RETURNING`` syntaxes.   ``INSERT..RETURNING`` is used by default
-for single-row INSERT statements in order to fetch newly generated
-primary key identifiers.   To specify an explicit ``RETURNING`` clause,
-use the :meth:`._UpdateBase.returning` method on a per-statement basis::
-
-    # INSERT..RETURNING
-    result = table.insert().returning(table.c.col1, table.c.col2).\\
-        values(name='foo')
-    print result.fetchall()
-
-    # UPDATE..RETURNING
-    result = table.update().returning(table.c.col1, table.c.col2).\\
-        where(table.c.name=='foo').values(name='bar')
-    print result.fetchall()
-
-    # DELETE..RETURNING
-    result = table.delete().returning(table.c.col1, table.c.col2).\\
-        where(table.c.name=='foo')
-    print result.fetchall()
-
-.. _postgresql_match:
-
-Full Text Search
-----------------
-
-SQLAlchemy makes available the Postgresql ``@@`` operator via the
-:meth:`.ColumnElement.match` method on any textual column expression.
-On a Postgresql dialect, an expression like the following::
-
-    select([sometable.c.text.match("search string")])
-
-will emit to the database::
-
-    SELECT text @@ to_tsquery('search string') FROM table
-
-The Postgresql text search functions such as ``to_tsquery()``
-and ``to_tsvector()`` are available
-explicitly using the standard :attr:`.func` construct.  For example::
-
-    select([
-        func.to_tsvector('fat cats ate rats').match('cat & rat')
-    ])
-
-Emits the equivalent of::
-
-    SELECT to_tsvector('fat cats ate rats') @@ to_tsquery('cat & rat')
-
-The :class:`.postgresql.TSVECTOR` type can provide for explicit CAST::
-
-    from sqlalchemy.dialects.postgresql import TSVECTOR
-    from sqlalchemy import select, cast
-    select([cast("some text", TSVECTOR)])
-
-produces a statement equivalent to::
-
-    SELECT CAST('some text' AS TSVECTOR) AS anon_1
-
-
-FROM ONLY ...
-------------------------
-
-The dialect supports PostgreSQL's ONLY keyword for targeting only a particular
-table in an inheritance hierarchy. This can be used to produce the
-``SELECT ... FROM ONLY``, ``UPDATE ONLY ...``, and ``DELETE FROM ONLY ...``
-syntaxes. It uses SQLAlchemy's hints mechanism::
-
-    # SELECT ... FROM ONLY ...
-    result = table.select().with_hint(table, 'ONLY', 'postgresql')
-    print result.fetchall()
-
-    # UPDATE ONLY ...
-    table.update(values=dict(foo='bar')).with_hint('ONLY',
-                                                   dialect_name='postgresql')
-
-    # DELETE FROM ONLY ...
-    table.delete().with_hint('ONLY', dialect_name='postgresql')
-
-.. _postgresql_indexes:
-
-Postgresql-Specific Index Options
----------------------------------
-
-Several extensions to the :class:`.Index` construct are available, specific
-to the PostgreSQL dialect.
-
-Partial Indexes
-^^^^^^^^^^^^^^^^
-
-Partial indexes add criterion to the index definition so that the index is
-applied to a subset of rows.   These can be specified on :class:`.Index`
-using the ``postgresql_where`` keyword argument::
-
-  Index('my_index', my_table.c.id, postgresql_where=tbl.c.value > 10)
-
-Operator Classes
-^^^^^^^^^^^^^^^^^
-
-PostgreSQL allows the specification of an *operator class* for each column of
-an index (see
-http://www.postgresql.org/docs/8.3/interactive/indexes-opclass.html).
-The :class:`.Index` construct allows these to be specified via the
-``postgresql_ops`` keyword argument::
-
-    Index('my_index', my_table.c.id, my_table.c.data,
-                            postgresql_ops={
-                                'data': 'text_pattern_ops',
-                                'id': 'int4_ops'
-                            })
-
-.. versionadded:: 0.7.2
-    ``postgresql_ops`` keyword argument to :class:`.Index` construct.
-
-Note that the keys in the ``postgresql_ops`` dictionary are the "key" name of
-the :class:`.Column`, i.e. the name used to access it from the ``.c``
-collection of :class:`.Table`, which can be configured to be different than
-the actual name of the column as expressed in the database.
-
-Index Types
-^^^^^^^^^^^^
-
-PostgreSQL provides several index types: B-Tree, Hash, GiST, and GIN, as well
-as the ability for users to create their own (see
-http://www.postgresql.org/docs/8.3/static/indexes-types.html). These can be
-specified on :class:`.Index` using the ``postgresql_using`` keyword argument::
-
-    Index('my_index', my_table.c.data, postgresql_using='gin')
-
-The value passed to the keyword argument will be simply passed through to the
-underlying CREATE INDEX command, so it *must* be a valid index type for your
-version of PostgreSQL.

-    to 1-based indexing.  The operator produces binary expression
-    constructs which will produce the appropriate SQL, both for
-    SELECT statements::
-
-        select([mytable.c.data[5], mytable.c.data[2:7]])
-
-    as well as UPDATE statements when the :meth:`.Update.values` method
-    is used::
-
-        mytable.update().values({
-            mytable.c.data[5]: 7,
-            mytable.c.data[2:7]: [1, 2, 3]
-        })
-
-    :class:`.ARRAY` provides special methods for containment operations,
-    e.g.::
-
-        mytable.c.data.contains([1, 2])
-
-    For a full list of special methods see :class:`.ARRAY.Comparator`.
-
-    .. versionadded:: 0.8 Added support for index and slice operations
-       to the :class:`.ARRAY` type, including support for UPDATE
-       statements, and special array containment operations.
-
-    The :class:`.ARRAY` type may not be supported on all DBAPIs.
-    It is known to work on psycopg2 and not pg8000.
-
-    See also:
-

-    The :class:`.JSON` type, when used with the SQLAlchemy ORM, does not detect

-    for a simple example involving a dictionary.
-
-    Custom serializers and deserializers are specified at the dialect level,
-    that is using :func:`.create_engine`.  The reason for this is that when
-    using psycopg2, the DBAPI only allows serializers at the per-cursor
-    or per-connection level.   E.g.::

-                        )
-

-    against the database using ``psycopg2.extras.register_default_json``.

-    :url: http://pypi.python.org/pypi/psycopg2/
-
-psycopg2 Connect Arguments
------------------------------------
-
-psycopg2-specific keyword arguments which are accepted by
-:func:`.create_engine()` are:
-
-* ``server_side_cursors``: Enable the usage of "server side cursors" for SQL
-  statements which support this feature. What this essentially means from a
-  psycopg2 point of view is that the cursor is created using a name, e.g.
-  ``connection.cursor('some name')``, which has the effect that result rows are
-  not immediately pre-fetched and buffered after statement execution, but are
-  instead left on the server and only retrieved as needed. SQLAlchemy's
-  :class:`~sqlalchemy.engine.ResultProxy` uses special row-buffering
-  behavior when this feature is enabled, such that groups of 100 rows at a
-  time are fetched over the wire to reduce conversational overhead.
-  Note that the ``stream_results=True`` execution option is a more targeted
-  way of enabling this mode on a per-execution basis.
-* ``use_native_unicode``: Enable the usage of Psycopg2 "native unicode" mode
-  per connection.  True by default.
-* ``isolation_level``: This option, available for all Posgtresql dialects,
-  includes the ``AUTOCOMMIT`` isolation level when using the psycopg2
-  dialect.  See :ref:`psycopg2_isolation_level`.
-
-
-Unix Domain Connections
-------------------------
-
-psycopg2 supports connecting via Unix domain connections.   When the ``host``
-portion of the URL is omitted, SQLAlchemy passes ``None`` to psycopg2,
-which specifies Unix-domain communication rather than TCP/IP communication::
-
-    create_engine("postgresql+psycopg2://user:password@/dbname")
-
-By default, the socket file used is to connect to a Unix-domain socket
-in ``/tmp``, or whatever socket directory was specified when PostgreSQL
-was built.  This value can be overridden by passing a pathname to psycopg2,
-using ``host`` as an additional keyword argument::
-
-    create_engine("postgresql+psycopg2://user:password@/dbname?host=/var/lib/postgresql")
-
-See also:
-
-`PQconnectdbParams <http://www.postgresql.org/docs/9.1/static/libpq-connect.html#LIBPQ-PQCONNECTDBPARAMS>`_
-
-Per-Statement/Connection Execution Options
--------------------------------------------
-
-The following DBAPI-specific options are respected when used with
-:meth:`.Connection.execution_options`, :meth:`.Executable.execution_options`,
-:meth:`.Query.execution_options`, in addition to those not specific to DBAPIs:
-
-* isolation_level - Set the transaction isolation level for the lifespan of a
-  :class:`.Connection` (can only be set on a connection, not a statement
-  or query).   See :ref:`psycopg2_isolation_level`.
-
-* stream_results - Enable or disable usage of psycopg2 server side cursors -
-  this feature makes use of "named" cursors in combination with special
-  result handling methods so that result rows are not fully buffered.
-  If ``None`` or not set, the ``server_side_cursors`` option of the
-  :class:`.Engine` is used.
-
-Unicode
--------
-
-By default, the psycopg2 driver uses the ``psycopg2.extensions.UNICODE``
-extension, such that the DBAPI receives and returns all strings as Python
-Unicode objects directly - SQLAlchemy passes these values through without
-change.   Psycopg2 here will encode/decode string values based on the
-current "client encoding" setting; by default this is the value in
-the ``postgresql.conf`` file, which often defaults to ``SQL_ASCII``.
-Typically, this can be changed to ``utf-8``, as a more useful default::
-
-    #client_encoding = sql_ascii # actually, defaults to database
-                                 # encoding
-    client_encoding = utf8
-
-A second way to affect the client encoding is to set it within Psycopg2
-locally.   SQLAlchemy will call psycopg2's ``set_client_encoding()``
-method (see: http://initd.org/psycopg/docs/connection.html#connection.set_client_encoding)
-on all new connections based on the value passed to
-:func:`.create_engine` using the ``client_encoding`` parameter::
-
-    engine = create_engine("postgresql://user:pass@host/dbname", client_encoding='utf8')
-
-This overrides the encoding specified in the Postgresql client configuration.
-
-.. versionadded:: 0.7.3
-    The psycopg2-specific ``client_encoding`` parameter to
-    :func:`.create_engine`.
-
-SQLAlchemy can also be instructed to skip the usage of the psycopg2
-``UNICODE`` extension and to instead utilize it's own unicode encode/decode
-services, which are normally reserved only for those DBAPIs that don't
-fully support unicode directly.  Passing ``use_native_unicode=False`` to
-:func:`.create_engine` will disable usage of ``psycopg2.extensions.UNICODE``.
-SQLAlchemy will instead encode data itself into Python bytestrings on the way
-in and coerce from bytes on the way back,
-using the value of the :func:`.create_engine` ``encoding`` parameter, which
-defaults to ``utf-8``.
-SQLAlchemy's own unicode encode/decode functionality is steadily becoming
-obsolete as more DBAPIs support unicode fully along with the approach of
-Python 3; in modern usage psycopg2 should be relied upon to handle unicode.
-
-Transactions
-------------
-
-The psycopg2 dialect fully supports SAVEPOINT and two-phase commit operations.
-
-.. _psycopg2_isolation_level:
-
-Psycopg2 Transaction Isolation Level
--------------------------------------
-
-As discussed in :ref:`postgresql_isolation_level`,
-all Postgresql dialects support setting of transaction isolation level
-both via the ``isolation_level`` parameter passed to :func:`.create_engine`,
-as well as the ``isolation_level`` argument used by :meth:`.Connection.execution_options`.
-When using the psycopg2 dialect, these options make use of
-psycopg2's ``set_isolation_level()`` connection method, rather than
-emitting a Postgresql directive; this is because psycopg2's API-level
-setting is always emitted at the start of each transaction in any case.
-
-The psycopg2 dialect supports these constants for isolation level:
-
-* ``READ COMMITTED``
-* ``READ UNCOMMITTED``
-* ``REPEATABLE READ``
-* ``SERIALIZABLE``
-* ``AUTOCOMMIT``
-
-.. versionadded:: 0.8.2 support for AUTOCOMMIT isolation level when using
-   psycopg2.
-
-
-NOTICE logging
----------------
-
-The psycopg2 dialect will log Postgresql NOTICE messages via the
-``sqlalchemy.dialects.postgresql`` logger::
-
-    import logging
-    logging.getLogger('sqlalchemy.dialects.postgresql').setLevel(logging.INFO)
-
-.. _psycopg2_hstore::
-
-HSTORE type
-------------
-
-The ``psycopg2`` DBAPI includes an extension to natively handle marshalling of the
-HSTORE type.   The SQLAlchemy psycopg2 dialect will enable this extension
-by default when it is detected that the target database has the HSTORE
-type set up for use.   In other words, when the dialect makes the first
-connection, a sequence like the following is performed:
-
-1. Request the available HSTORE oids using ``psycopg2.extras.HstoreAdapter.get_oids()``.
-   If this function returns a list of HSTORE identifiers, we then determine that
-   the ``HSTORE`` extension is present.
-
-2. If the ``use_native_hstore`` flag is at it's default of ``True``, and
-   we've detected that ``HSTORE`` oids are available, the
-   ``psycopg2.extensions.register_hstore()`` extension is invoked for all
-   connections.
-
-The ``register_hstore()`` extension has the effect of **all Python dictionaries
-being accepted as parameters regardless of the type of target column in SQL**.
-The dictionaries are converted by this extension into a textual HSTORE expression.
-If this behavior is not desired, disable the
-use of the hstore extension by setting ``use_native_hstore`` to ``False`` as follows::
-
-    engine = create_engine("postgresql+psycopg2://scott:tiger@localhost/test",
-                use_native_hstore=False)
-
-The ``HSTORE`` type is **still supported** when the ``psycopg2.extensions.register_hstore()``
-extension is not used.  It merely means that the coercion between Python dictionaries and the HSTORE
-string format, on both the parameter side and the result side, will take
-place within SQLAlchemy's own marshalling logic, and not that of ``psycopg2`` which
-may be more performant.

-.. dialect:: sqlite
-    :name: SQLite
-
-
-Date and Time Types
--------------------
-
-SQLite does not have built-in DATE, TIME, or DATETIME types, and pysqlite does
-not provide out of the box functionality for translating values between Python
-`datetime` objects and a SQLite-supported format. SQLAlchemy's own
-:class:`~sqlalchemy.types.DateTime` and related types provide date formatting
-and parsing functionality when SQlite is used. The implementation classes are
-:class:`~.sqlite.DATETIME`, :class:`~.sqlite.DATE` and :class:`~.sqlite.TIME`.
-These types represent dates and times as ISO formatted strings, which also
-nicely support ordering. There's no reliance on typical "libc" internals for
-these functions so historical dates are fully supported.
-
-Auto Incrementing Behavior
---------------------------
-
-Background on SQLite's autoincrement is at: http://sqlite.org/autoinc.html
-
-Two things to note:
-
-* The AUTOINCREMENT keyword is **not** required for SQLite tables to
-  generate primary key values automatically. AUTOINCREMENT only means that the
-  algorithm used to generate ROWID values should be slightly different.
-* SQLite does **not** generate primary key (i.e. ROWID) values, even for
-  one column, if the table has a composite (i.e. multi-column) primary key.
-  This is regardless of the AUTOINCREMENT keyword being present or not.
-
-To specifically render the AUTOINCREMENT keyword on the primary key column when
-rendering DDL, add the flag ``sqlite_autoincrement=True`` to the Table
-construct::
-
-    Table('sometable', metadata,
-            Column('id', Integer, primary_key=True),
-            sqlite_autoincrement=True)
-
-Transaction Isolation Level
----------------------------
-
-:func:`.create_engine` accepts an ``isolation_level`` parameter which results
-in the command ``PRAGMA read_uncommitted <level>`` being invoked for every new
-connection. Valid values for this parameter are ``SERIALIZABLE`` and ``READ
-UNCOMMITTED`` corresponding to a value of 0 and 1, respectively. See the
-section :ref:`pysqlite_serializable` for an important workaround when using
-serializable isolation with Pysqlite.
-
-Database Locking Behavior / Concurrency
----------------------------------------
-
-Note that SQLite is not designed for a high level of concurrency. The database
-itself, being a file, is locked completely during write operations and within
-transactions, meaning exactly one connection has exclusive access to the
-database during this period - all other connections will be blocked during this
-time.
-
-The Python DBAPI specification also calls for a connection model that is always
-in a transaction; there is no BEGIN method, only commit and rollback. This
-implies that a SQLite DBAPI driver would technically allow only serialized
-access to a particular database file at all times. The pysqlite driver attempts
-to ameliorate this by deferring the actual BEGIN statement until the first DML
-(INSERT, UPDATE, or DELETE) is received within a transaction. While this breaks
-serializable isolation, it at least delays the exclusive locking inherent in
-SQLite's design.
-
-SQLAlchemy's default mode of usage with the ORM is known as "autocommit=False",
-which means the moment the :class:`.Session` begins to be used, a transaction
-is begun. As the :class:`.Session` is used, the autoflush feature, also on by
-default, will flush out pending changes to the database before each query. The
-effect of this is that a :class:`.Session` used in its default mode will often
-emit DML early on, long before the transaction is actually committed. This
-again will have the effect of serializing access to the SQLite database. If
-highly concurrent reads are desired against the SQLite database, it is advised
-that the autoflush feature be disabled, and potentially even that autocommit be
-re-enabled, which has the effect of each SQL statement and flush committing
-changes immediately.
-
-For more information on SQLite's lack of concurrency by design, please see
-`Situations Where Another RDBMS May Work Better - High Concurrency
-<http://www.sqlite.org/whentouse.html>`_ near the bottom of the page.
-
-.. _sqlite_foreign_keys:
-
-Foreign Key Support
--------------------
-
-SQLite supports FOREIGN KEY syntax when emitting CREATE statements for tables,
-however by default these constraints have no effect on the operation of the
-table.
-
-Constraint checking on SQLite has three prerequisites:
-
-* At least version 3.6.19 of SQLite must be in use
-* The SQLite libary must be compiled *without* the SQLITE_OMIT_FOREIGN_KEY
-  or SQLITE_OMIT_TRIGGER symbols enabled.
-* The ``PRAGMA foreign_keys = ON`` statement must be emitted on all connections
-  before use.
-
-SQLAlchemy allows for the ``PRAGMA`` statement to be emitted automatically for
-new connections through the usage of events::
-
-    from sqlalchemy.engine import Engine
-    from sqlalchemy import event
-
-    @event.listens_for(Engine, "connect")
-    def set_sqlite_pragma(dbapi_connection, connection_record):
-        cursor = dbapi_connection.cursor()
-        cursor.execute("PRAGMA foreign_keys=ON")
-        cursor.close()
-
-.. seealso::
-
-    `SQLite Foreign Key Support <http://www.sqlite.org/foreignkeys.html>`_ - on
-    the SQLite web site.
-
-    :ref:`event_toplevel` - SQLAlchemy event API.
-
-.. _sqlite_type_reflection:
-
-Type Reflection
----------------
-
-SQLite types are unlike those of most other database backends, in that
-the string name of the type usually does not correspond to a "type" in a
-one-to-one fashion.  Instead, SQLite links per-column typing behavior
-to one of five so-called "type affinities" based on a string matching
-pattern for the type.
-
-SQLAlchemy's reflection process, when inspecting types, uses a simple
-lookup table to link the keywords returned to provided SQLAlchemy types.
-This lookup table is present within the SQLite dialect as it is for all
-other dialects.  However, the SQLite dialect has a different "fallback"
-routine for when a particular type name is not located in the lookup map;
-it instead implements the SQLite "type affinity" scheme located at
-http://www.sqlite.org/datatype3.html section 2.1.
-
-The provided typemap will make direct associations from an exact string
-name match for the following types:
-
-:class:`~.types.BIGINT`, :class:`~.types.BLOB`,
-:class:`~.types.BOOLEAN`, :class:`~.types.BOOLEAN`,
-:class:`~.types.CHAR`, :class:`~.types.DATE`,
-:class:`~.types.DATETIME`, :class:`~.types.FLOAT`,
-:class:`~.types.DECIMAL`, :class:`~.types.FLOAT`,
-:class:`~.types.INTEGER`, :class:`~.types.INTEGER`,
-:class:`~.types.NUMERIC`, :class:`~.types.REAL`,
-:class:`~.types.SMALLINT`, :class:`~.types.TEXT`,
-:class:`~.types.TIME`, :class:`~.types.TIMESTAMP`,
-:class:`~.types.VARCHAR`, :class:`~.types.NVARCHAR`,
-:class:`~.types.NCHAR`
-
-When a type name does not match one of the above types, the "type affinity"
-lookup is used instead:
-
-* :class:`~.types.INTEGER` is returned if the type name includes the
-  string ``INT``
-* :class:`~.types.TEXT` is returned if the type name includes the
-  string ``CHAR``, ``CLOB`` or ``TEXT``
-* :class:`~.types.NullType` is returned if the type name includes the
-  string ``BLOB``
-* :class:`~.types.REAL` is returned if the type name includes the string
-  ``REAL``, ``FLOA`` or ``DOUB``.
-* Otherwise, the :class:`~.types.NUMERIC` type is used.
-
-.. versionadded:: 0.9.3 Support for SQLite type affinity rules when reflecting
-   columns.

-.. dialect:: sqlite+pysqlite
-    :name: pysqlite
-    :dbapi: sqlite3
-    :connectstring: sqlite+pysqlite:///file_path
-    :url: http://docs.python.org/library/sqlite3.html
-
-    Note that ``pysqlite`` is the same driver as the ``sqlite3``
-    module included with the Python distribution.
-
-Driver
-------
-
-When using Python 2.5 and above, the built in ``sqlite3`` driver is
-already installed and no additional installation is needed.  Otherwise,
-the ``pysqlite2`` driver needs to be present.  This is the same driver as
-``sqlite3``, just with a different name.
-
-The ``pysqlite2`` driver will be loaded first, and if not found, ``sqlite3``
-is loaded.  This allows an explicitly installed pysqlite driver to take
-precedence over the built in one.   As with all dialects, a specific
-DBAPI module may be provided to :func:`~sqlalchemy.create_engine()` to control
-this explicitly::
-
-    from sqlite3 import dbapi2 as sqlite
-    e = create_engine('sqlite+pysqlite:///file.db', module=sqlite)
-
-
-Connect Strings
----------------
-
-The file specification for the SQLite database is taken as the "database"
-portion of the URL.  Note that the format of a SQLAlchemy url is::
-
-    driver://user:pass@host/database
-
-This means that the actual filename to be used starts with the characters to
-the **right** of the third slash.   So connecting to a relative filepath
-looks like::
-
-    # relative path
-    e = create_engine('sqlite:///path/to/database.db')
-
-An absolute path, which is denoted by starting with a slash, means you
-need **four** slashes::
-
-    # absolute path
-    e = create_engine('sqlite:////path/to/database.db')
-
-To use a Windows path, regular drive specifications and backslashes can be
-used. Double backslashes are probably needed::
-
-    # absolute path on Windows
-    e = create_engine('sqlite:///C:\\\\path\\\\to\\\\database.db')
-
-The sqlite ``:memory:`` identifier is the default if no filepath is
-present.  Specify ``sqlite://`` and nothing else::
-
-    # in-memory database
-    e = create_engine('sqlite://')
-
-Compatibility with sqlite3 "native" date and datetime types
------------------------------------------------------------
-
-The pysqlite driver includes the sqlite3.PARSE_DECLTYPES and
-sqlite3.PARSE_COLNAMES options, which have the effect of any column
-or expression explicitly cast as "date" or "timestamp" will be converted
-to a Python date or datetime object.  The date and datetime types provided
-with the pysqlite dialect are not currently compatible with these options,
-since they render the ISO date/datetime including microseconds, which
-pysqlite's driver does not.   Additionally, SQLAlchemy does not at
-this time automatically render the "cast" syntax required for the
-freestanding functions "current_timestamp" and "current_date" to return
-datetime/date types natively.   Unfortunately, pysqlite
-does not provide the standard DBAPI types in ``cursor.description``,
-leaving SQLAlchemy with no way to detect these types on the fly
-without expensive per-row type checks.
-
-Keeping in mind that pysqlite's parsing option is not recommended,
-nor should be necessary, for use with SQLAlchemy, usage of PARSE_DECLTYPES
-can be forced if one configures "native_datetime=True" on create_engine()::
-
-    engine = create_engine('sqlite://',
-        connect_args={'detect_types': sqlite3.PARSE_DECLTYPES|sqlite3.PARSE_COLNAMES},
-        native_datetime=True
-    )
-
-With this flag enabled, the DATE and TIMESTAMP types (but note - not the
-DATETIME or TIME types...confused yet ?) will not perform any bind parameter
-or result processing. Execution of "func.current_date()" will return a string.
-"func.current_timestamp()" is registered as returning a DATETIME type in
-SQLAlchemy, so this function still receives SQLAlchemy-level result processing.
-
-.. _pysqlite_threading_pooling:
-
-Threading/Pooling Behavior
----------------------------
-
-Pysqlite's default behavior is to prohibit the usage of a single connection
-in more than one thread.   This is originally intended to work with older
-versions of SQLite that did not support multithreaded operation under
-various circumstances.  In particular, older SQLite versions
-did not allow a ``:memory:`` database to be used in multiple threads
-under any circumstances.
-
-Pysqlite does include a now-undocumented flag known as
-``check_same_thread`` which will disable this check, however note that pysqlite
-connections are still not safe to use in concurrently in multiple threads.
-In particular, any statement execution calls would need to be externally
-mutexed, as Pysqlite does not provide for thread-safe propagation of error
-messages among other things.   So while even ``:memory:`` databases can be
-shared among threads in modern SQLite, Pysqlite doesn't provide enough
-thread-safety to make this usage worth it.
-
-SQLAlchemy sets up pooling to work with Pysqlite's default behavior:
-
-* When a ``:memory:`` SQLite database is specified, the dialect by default
-  will use :class:`.SingletonThreadPool`. This pool maintains a single
-  connection per thread, so that all access to the engine within the current
-  thread use the same ``:memory:`` database - other threads would access a
-  different ``:memory:`` database.
-* When a file-based database is specified, the dialect will use
-  :class:`.NullPool` as the source of connections. This pool closes and
-  discards connections which are returned to the pool immediately. SQLite
-  file-based connections have extremely low overhead, so pooling is not
-  necessary. The scheme also prevents a connection from being used again in
-  a different thread and works best with SQLite's coarse-grained file locking.
-
-  .. versionchanged:: 0.7
-      Default selection of :class:`.NullPool` for SQLite file-based databases.
-      Previous versions select :class:`.SingletonThreadPool` by
-      default for all SQLite databases.
-
-
-Using a Memory Database in Multiple Threads
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-To use a ``:memory:`` database in a multithreaded scenario, the same connection
-object must be shared among threads, since the database exists
-only within the scope of that connection.   The
-:class:`.StaticPool` implementation will maintain a single connection
-globally, and the ``check_same_thread`` flag can be passed to Pysqlite
-as ``False``::
-
-    from sqlalchemy.pool import StaticPool
-    engine = create_engine('sqlite://',
-                        connect_args={'check_same_thread':False},
-                        poolclass=StaticPool)
-
-Note that using a ``:memory:`` database in multiple threads requires a recent
-version of SQLite.
-
-Using Temporary Tables with SQLite
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Due to the way SQLite deals with temporary tables, if you wish to use a
-temporary table in a file-based SQLite database across multiple checkouts
-from the connection pool, such as when using an ORM :class:`.Session` where
-the temporary table should continue to remain after :meth:`.Session.commit` or
-:meth:`.Session.rollback` is called, a pool which maintains a single connection must
-be used.   Use :class:`.SingletonThreadPool` if the scope is only needed
-within the current thread, or :class:`.StaticPool` is scope is needed within
-multiple threads for this case::
-
-    # maintain the same connection per thread
-    from sqlalchemy.pool import SingletonThreadPool
-    engine = create_engine('sqlite:///mydb.db',
-                        poolclass=SingletonThreadPool)
-
-
-    # maintain the same connection across all threads
-    from sqlalchemy.pool import StaticPool
-    engine = create_engine('sqlite:///mydb.db',
-                        poolclass=StaticPool)
-
-Note that :class:`.SingletonThreadPool` should be configured for the number
-of threads that are to be used; beyond that number, connections will be
-closed out in a non deterministic way.
-
-Unicode
--------
-
-The pysqlite driver only returns Python ``unicode`` objects in result sets,
-never plain strings, and accommodates ``unicode`` objects within bound
-parameter values in all cases.   Regardless of the SQLAlchemy string type in
-use, string-based result values will by Python ``unicode`` in Python 2.
-The :class:`.Unicode` type should still be used to indicate those columns that
-require unicode, however, so that non-``unicode`` values passed inadvertently
-will emit a warning.  Pysqlite will emit an error if a non-``unicode`` string
-is passed containing non-ASCII characters.
-
-.. _pysqlite_serializable:
-
-Serializable Transaction Isolation
-----------------------------------
-
-The pysqlite DBAPI driver has a long-standing bug in which transactional
-state is not begun until the first DML statement, that is INSERT, UPDATE
-or DELETE, is emitted.  A SELECT statement will not cause transactional
-state to begin.   While this mode of usage is fine for typical situations
-and has the advantage that the SQLite database file is not prematurely
-locked, it breaks serializable transaction isolation, which requires
-that the database file be locked upon any SQL being emitted.
-
-To work around this issue, the ``BEGIN`` keyword can be emitted
-at the start of each transaction.   The following recipe establishes
-a :meth:`.ConnectionEvents.begin` handler to achieve this::
-
-    from sqlalchemy import create_engine, event
-
-    engine = create_engine("sqlite:///myfile.db", isolation_level='SERIALIZABLE')
-
-    @event.listens_for(engine, "begin")
-    def do_begin(conn):
-        conn.execute("BEGIN")

-"""SQL connections, SQL execution and high-level DB-API interface.
-
-The engine package defines the basic components used to interface
-DB-API modules with higher-level statement construction,
-connection-management, execution and result contexts.  The primary
-"entry point" class into this package is the Engine and it's public
-constructor ``create_engine()``.
-
-This package includes:
-
-base.py
-    Defines interface classes and some implementation classes which
-    comprise the basic components used to interface between a DB-API,
-    constructed and plain-text statements, connections, transactions,
-    and results.
-
-default.py
-    Contains default implementations of some of the components defined
-    in base.py.  All current database dialects use the classes in
-    default.py as base classes for their own database-specific
-    implementations.
-
-strategies.py
-    The mechanics of constructing ``Engine`` objects are represented
-    here.  Defines the ``EngineStrategy`` class which represents how
-    to go from arguments specified to the ``create_engine()``
-    function, to a fully constructed ``Engine``, including
-    initialization of connection pooling, dialects, and specific
-    subclasses of ``Engine``.
-
-threadlocal.py
-    The ``TLEngine`` class is defined here, which is a subclass of
-    the generic ``Engine`` and tracks ``Connection`` and
-    ``Transaction`` objects against the identity of the current
-    thread.  This allows certain programming patterns based around
-    the concept of a "thread-local connection" to be possible.
-    The ``TLEngine`` is created by using the "threadlocal" engine
-    strategy in conjunction with the ``create_engine()`` function.
-
-url.py
-    Defines the ``URL`` class which represents the individual
-    components of a string URL passed to ``create_engine()``.  Also
-    defines a basic module-loading strategy for the dialect specifier
-    within a URL.

-def create_engine(*args, **kwargs):
-    """Create a new :class:`.Engine` instance.
-
-    The standard calling form is to send the URL as the
-    first positional argument, usually a string
-    that indicates database dialect and connection arguments::
-
-
-        engine = create_engine("postgresql://scott:tiger@localhost/test")
-
-    Additional keyword arguments may then follow it which
-    establish various options on the resulting :class:`.Engine`
-    and its underlying :class:`.Dialect` and :class:`.Pool`
-    constructs::
-
-        engine = create_engine("mysql://scott:tiger@hostname/dbname",
-                                    encoding='latin1', echo=True)
-
-    The string form of the URL is
-    ``dialect[+driver]://user:password@host/dbname[?key=value..]``, where
-    ``dialect`` is a database name such as ``mysql``, ``oracle``,
-    ``postgresql``, etc., and ``driver`` the name of a DBAPI, such as
-    ``psycopg2``, ``pyodbc``, ``cx_oracle``, etc.  Alternatively,
-    the URL can be an instance of :class:`~sqlalchemy.engine.url.URL`.
-
-    ``**kwargs`` takes a wide variety of options which are routed
-    towards their appropriate components.  Arguments may be specific to
-    the :class:`.Engine`, the underlying :class:`.Dialect`, as well as the
-    :class:`.Pool`.  Specific dialects also accept keyword arguments that
-    are unique to that dialect.   Here, we describe the parameters
-    that are common to most :func:`.create_engine()` usage.
-
-    Once established, the newly resulting :class:`.Engine` will
-    request a connection from the underlying :class:`.Pool` once
-    :meth:`.Engine.connect` is called, or a method which depends on it
-    such as :meth:`.Engine.execute` is invoked.   The :class:`.Pool` in turn
-    will establish the first actual DBAPI connection when this request
-    is received.   The :func:`.create_engine` call itself does **not**
-    establish any actual DBAPI connections directly.
-
-    .. seealso::
-
-        :doc:`/core/engines`
-
-        :doc:`/dialects/index`
-
-        :ref:`connections_toplevel`
-
-    :param case_sensitive=True: if False, result column names
-       will match in a case-insensitive fashion, that is,
-       ``row['SomeColumn']``.
-
-       .. versionchanged:: 0.8
-           By default, result row names match case-sensitively.
-           In version 0.7 and prior, all matches were case-insensitive.
-
-    :param connect_args: a dictionary of options which will be
-        passed directly to the DBAPI's ``connect()`` method as
-        additional keyword arguments.  See the example
-        at :ref:`custom_dbapi_args`.
-
-    :param convert_unicode=False: if set to True, sets
-        the default behavior of ``convert_unicode`` on the
-        :class:`.String` type to ``True``, regardless
-        of a setting of ``False`` on an individual
-        :class:`.String` type, thus causing all :class:`.String`
-        -based columns
-        to accommodate Python ``unicode`` objects.  This flag
-        is useful as an engine-wide setting when using a
-        DBAPI that does not natively support Python
-        ``unicode`` objects and raises an error when
-        one is received (such as pyodbc with FreeTDS).
-
-        See :class:`.String` for further details on
-        what this flag indicates.
-
-    :param creator: a callable which returns a DBAPI connection.
-        This creation function will be passed to the underlying
-        connection pool and will be used to create all new database
-        connections. Usage of this function causes connection
-        parameters specified in the URL argument to be bypassed.
-
-    :param echo=False: if True, the Engine will log all statements
-        as well as a repr() of their parameter lists to the engines
-        logger, which defaults to sys.stdout. The ``echo`` attribute of
-        ``Engine`` can be modified at any time to turn logging on and
-        off. If set to the string ``"debug"``, result rows will be
-        printed to the standard output as well. This flag ultimately
-        controls a Python logger; see :ref:`dbengine_logging` for
-        information on how to configure logging directly.
-
-    :param echo_pool=False: if True, the connection pool will log
-        all checkouts/checkins to the logging stream, which defaults to
-        sys.stdout. This flag ultimately controls a Python logger; see
-        :ref:`dbengine_logging` for information on how to configure logging
-        directly.
-
-    :param encoding: Defaults to ``utf-8``.  This is the string
-        encoding used by SQLAlchemy for string encode/decode
-        operations which occur within SQLAlchemy, **outside of
-        the DBAPI.**  Most modern DBAPIs feature some degree of
-        direct support for Python ``unicode`` objects,
-        what you see in Python 2 as a string of the form
-        ``u'some string'``.  For those scenarios where the
-        DBAPI is detected as not supporting a Python ``unicode``
-        object, this encoding is used to determine the
-        source/destination encoding.  It is **not used**
-        for those cases where the DBAPI handles unicode
-        directly.
-
-        To properly configure a system to accommodate Python
-        ``unicode`` objects, the DBAPI should be
-        configured to handle unicode to the greatest
-        degree as is appropriate - see
-        the notes on unicode pertaining to the specific
-        target database in use at :ref:`dialect_toplevel`.
-
-        Areas where string encoding may need to be accommodated
-        outside of the DBAPI include zero or more of:
-
-        * the values passed to bound parameters, corresponding to
-          the :class:`.Unicode` type or the :class:`.String` type
-          when ``convert_unicode`` is ``True``;
-        * the values returned in result set columns corresponding
-          to the :class:`.Unicode` type or the :class:`.String`
-          type when ``convert_unicode`` is ``True``;
-        * the string SQL statement passed to the DBAPI's
-          ``cursor.execute()`` method;
-        * the string names of the keys in the bound parameter
-          dictionary passed to the DBAPI's ``cursor.execute()``
-          as well as ``cursor.setinputsizes()`` methods;
-        * the string column names retrieved from the DBAPI's
-          ``cursor.description`` attribute.
-
-        When using Python 3, the DBAPI is required to support
-        *all* of the above values as Python ``unicode`` objects,
-        which in Python 3 are just known as ``str``.  In Python 2,
-        the DBAPI does not specify unicode behavior at all,
-        so SQLAlchemy must make decisions for each of the above
-        values on a per-DBAPI basis - implementations are
-        completely inconsistent in their behavior.
-
-    :param execution_options: Dictionary execution options which will
-        be applied to all connections.  See
-        :meth:`~sqlalchemy.engine.Connection.execution_options`
-
-    :param implicit_returning=True: When ``True``, a RETURNING-
-        compatible construct, if available, will be used to
-        fetch newly generated primary key values when a single row
-        INSERT statement is emitted with no existing returning()
-        clause.  This applies to those backends which support RETURNING
-        or a compatible construct, including Postgresql, Firebird, Oracle,
-        Microsoft SQL Server.   Set this to ``False`` to disable
-        the automatic usage of RETURNING.
-
-    :param label_length=None: optional integer value which limits
-        the size of dynamically generated column labels to that many
-        characters. If less than 6, labels are generated as
-        "_(counter)". If ``None``, the value of
-        ``dialect.max_identifier_length`` is used instead.
-
-    :param listeners: A list of one or more
-        :class:`~sqlalchemy.interfaces.PoolListener` objects which will
-        receive connection pool events.
-
-    :param logging_name:  String identifier which will be used within
-        the "name" field of logging records generated within the
-        "sqlalchemy.engine" logger. Defaults to a hexstring of the
-        object's id.
-
-    :param max_overflow=10: the number of connections to allow in
-        connection pool "overflow", that is connections that can be
-        opened above and beyond the pool_size setting, which defaults
-        to five. this is only used with :class:`~sqlalchemy.pool.QueuePool`.
-
-    :param module=None: reference to a Python module object (the module
-        itself, not its string name).  Specifies an alternate DBAPI module to
-        be used by the engine's dialect.  Each sub-dialect references a
-        specific DBAPI which will be imported before first connect.  This
-        parameter causes the import to be bypassed, and the given module to
-        be used instead. Can be used for testing of DBAPIs as well as to
-        inject "mock" DBAPI implementations into the :class:`.Engine`.
-
-    :param pool=None: an already-constructed instance of
-        :class:`~sqlalchemy.pool.Pool`, such as a
-        :class:`~sqlalchemy.pool.QueuePool` instance. If non-None, this
-        pool will be used directly as the underlying connection pool
-        for the engine, bypassing whatever connection parameters are
-        present in the URL argument. For information on constructing
-        connection pools manually, see :ref:`pooling_toplevel`.
-
-    :param poolclass=None: a :class:`~sqlalchemy.pool.Pool`
-        subclass, which will be used to create a connection pool
-        instance using the connection parameters given in the URL. Note
-        this differs from ``pool`` in that you don't actually
-        instantiate the pool in this case, you just indicate what type
-        of pool to be used.
-
-    :param pool_logging_name:  String identifier which will be used within
-       the "name" field of logging records generated within the
-       "sqlalchemy.pool" logger. Defaults to a hexstring of the object's
-       id.
-
-    :param pool_size=5: the number of connections to keep open
-        inside the connection pool. This used with
-        :class:`~sqlalchemy.pool.QueuePool` as
-        well as :class:`~sqlalchemy.pool.SingletonThreadPool`.  With
-        :class:`~sqlalchemy.pool.QueuePool`, a ``pool_size`` setting
-        of 0 indicates no limit; to disable pooling, set ``poolclass`` to
-        :class:`~sqlalchemy.pool.NullPool` instead.
-
-    :param pool_recycle=-1: this setting causes the pool to recycle
-        connections after the given number of seconds has passed. It
-        defaults to -1, or no timeout. For example, setting to 3600
-        means connections will be recycled after one hour. Note that
-        MySQL in particular will disconnect automatically if no
-        activity is detected on a connection for eight hours (although
-        this is configurable with the MySQLDB connection itself and the
-        server configuration as well).
-
-    :param pool_reset_on_return='rollback': set the "reset on return"
-        behavior of the pool, which is whether ``rollback()``,
-        ``commit()``, or nothing is called upon connections
-        being returned to the pool.  See the docstring for
-        ``reset_on_return`` at :class:`.Pool`.
-
-        .. versionadded:: 0.7.6
-
-    :param pool_timeout=30: number of seconds to wait before giving
-        up on getting a connection from the pool. This is only used
-        with :class:`~sqlalchemy.pool.QueuePool`.
-
-    :param strategy='plain': selects alternate engine implementations.
-        Currently available are:
-
-        * the ``threadlocal`` strategy, which is described in
-          :ref:`threadlocal_strategy`;
-        * the ``mock`` strategy, which dispatches all statement
-          execution to a function passed as the argument ``executor``.
-          See `example in the FAQ
-          <http://www.sqlalchemy.org/trac/wiki/FAQ#HowcanIgettheCREATETABLEDROPTABLEoutputasastring>`_.
-
-    :param executor=None: a function taking arguments

-
-        :param autocommit: Available on: Connection, statement.
-          When True, a COMMIT will be invoked after execution
-          when executed in 'autocommit' mode, i.e. when an explicit
-          transaction is not begun on the connection. Note that DBAPI
-          connections by default are always in a transaction - SQLAlchemy uses
-          rules applied to different kinds of statements to determine if
-          COMMIT will be invoked in order to provide its "autocommit" feature.
-          Typically, all INSERT/UPDATE/DELETE statements as well as
-          CREATE/DROP statements have autocommit behavior enabled; SELECT
-          constructs do not. Use this option when invoking a SELECT or other
-          specific SQL construct where COMMIT is desired (typically when
-          calling stored procedures and such), and an explicit
-          transaction is not in progress.
-
-        :param compiled_cache: Available on: Connection.
-          A dictionary where :class:`.Compiled` objects
-          will be cached when the :class:`.Connection` compiles a clause
-          expression into a :class:`.Compiled` object.
-          It is the user's responsibility to
-          manage the size of this dictionary, which will have keys
-          corresponding to the dialect, clause element, the column
-          names within the VALUES or SET clause of an INSERT or UPDATE,
-          as well as the "batch" mode for an INSERT or UPDATE statement.
-          The format of this dictionary is not guaranteed to stay the
-          same in future releases.
-
-          Note that the ORM makes use of its own "compiled" caches for
-          some operations, including flush operations.  The caching
-          used by the ORM internally supersedes a cache dictionary
-          specified here.
-
-        :param isolation_level: Available on: Connection.
-          Set the transaction isolation level for
-          the lifespan of this connection.   Valid values include
-          those string values accepted by the ``isolation_level``
-          parameter passed to :func:`.create_engine`, and are
-          database specific, including those for :ref:`sqlite_toplevel`,
-          :ref:`postgresql_toplevel` - see those dialect's documentation
-          for further info.
-
-          Note that this option necessarily affects the underlying
-          DBAPI connection for the lifespan of the originating
-          :class:`.Connection`, and is not per-execution. This
-          setting is not removed until the underlying DBAPI connection
-          is returned to the connection pool, i.e.
-          the :meth:`.Connection.close` method is called.
-
-        :param no_parameters: When ``True``, if the final parameter
-          list or dictionary is totally empty, will invoke the
-          statement on the cursor as ``cursor.execute(statement)``,
-          not passing the parameter collection at all.
-          Some DBAPIs such as psycopg2 and mysql-python consider
-          percent signs as significant only when parameters are
-          present; this option allows code to generate SQL
-          containing percent signs (and possibly other characters)
-          that is neutral regarding whether it's executed by the DBAPI
-          or piped into a script that's later invoked by

-            shard2 = primary_engine.execution_options(shard_id="shard2")

-        ``shard_id=shard1``, and ``shard2`` will produce :class:`.Connection`
-        objects that contain the execution option ``shard_id=shard2``.
-
-        An event handler can consume the above execution option to perform

-        time keeping track of which database we've established using the

-class Dialect(object):
-    """Define the behavior of a specific database and DB-API combination.
-
-    Any aspect of metadata definition, SQL query generation,
-    execution, result-set handling, or anything else which varies
-    between databases is defined under the general category of the
-    Dialect.  The Dialect acts as a factory for other
-    database-specific object implementations including
-    ExecutionContext, Compiled, DefaultGenerator, and TypeEngine.
-
-    All Dialects implement the following attributes:
-
-    name
-      identifying name for the dialect from a DBAPI-neutral point of view
-      (i.e. 'sqlite')
-
-    driver
-      identifying name for the dialect's DBAPI
-
-    positional
-      True if the paramstyle for this Dialect is positional.
-
-    paramstyle
-      the paramstyle to be used (some DB-APIs support multiple
-      paramstyles).
-
-    convert_unicode
-      True if Unicode conversion should be applied to all ``str``
-      types.
-
-    encoding
-      type of encoding to use for unicode, usually defaults to
-      'utf-8'.
-
-    statement_compiler
-      a :class:`.Compiled` class used to compile SQL statements
-
-    ddl_compiler
-      a :class:`.Compiled` class used to compile DDL statements
-
-    server_version_info
-      a tuple containing a version number for the DB backend in use.
-      This value is only available for supporting dialects, and is
-      typically populated during the initial connection to the database.
-
-    default_schema_name
-     the name of the default schema.  This value is only available for
-     supporting dialects, and is typically populated during the
-     initial connection to the database.
-
-    execution_ctx_cls
-      a :class:`.ExecutionContext` class used to handle statement execution
-
-    execute_sequence_format
-      either the 'tuple' or 'list' type, depending on what cursor.execute()
-      accepts for the second argument (they vary).
-
-    preparer
-      a :class:`~sqlalchemy.sql.compiler.IdentifierPreparer` class used to
-      quote identifiers.
-
-    supports_alter
-      ``True`` if the database supports ``ALTER TABLE``.
-
-    max_identifier_length
-      The maximum length of identifier names.
-
-    supports_unicode_statements
-      Indicate whether the DB-API can receive SQL statements as Python
-      unicode strings
-
-    supports_unicode_binds
-      Indicate whether the DB-API can receive string bind parameters
-      as Python unicode strings
-
-    supports_sane_rowcount
-      Indicate whether the dialect properly implements rowcount for
-      ``UPDATE`` and ``DELETE`` statements.
-
-    supports_sane_multi_rowcount
-      Indicate whether the dialect properly implements rowcount for
-      ``UPDATE`` and ``DELETE`` statements when executed via
-      executemany.
-
-    preexecute_autoincrement_sequences
-      True if 'implicit' primary key functions must be executed separately
-      in order to get their value.   This is currently oriented towards
-      Postgresql.
-
-    implicit_returning
-      use RETURNING or equivalent during INSERT execution in order to load
-      newly generated primary keys and other column defaults in one execution,
-      which are then available via inserted_primary_key.
-      If an insert statement has returning() specified explicitly,
-      the "implicit" functionality is not used and inserted_primary_key
-      will not be available.
-
-    dbapi_type_map
-      A mapping of DB-API type objects present in this Dialect's
-      DB-API implementation mapped to TypeEngine implementations used
-      by the dialect.
-
-      This is used to apply types to result sets based on the DB-API
-      types present in cursor.description; it only takes effect for
-      result sets against textual statements where no explicit
-      typemap was present.
-
-    colspecs
-      A dictionary of TypeEngine classes from sqlalchemy.types mapped
-      to subclasses that are specific to the dialect class.  This
-      dictionary is class-level only and is not accessed from the
-      dialect instance itself.
-
-    supports_default_values
-      Indicates if the construct ``INSERT INTO tablename DEFAULT
-      VALUES`` is supported
-
-    supports_sequences
-      Indicates if the dialect supports CREATE SEQUENCE or similar.
-
-    sequences_optional
-      If True, indicates if the "optional" flag on the Sequence() construct
-      should signal to not generate a CREATE SEQUENCE. Applies only to
-      dialects that support sequences. Currently used only to allow Postgresql
-      SERIAL to be used on a column that specifies Sequence() for usage on
-      other backends.
-
-    supports_native_enum
-      Indicates if the dialect supports a native ENUM construct.
-      This will prevent types.Enum from generating a CHECK
-      constraint when that type is used.
-
-    supports_native_boolean
-      Indicates if the dialect supports a native boolean construct.
-      This will prevent types.Boolean from generating a CHECK
-      constraint when that type is used.

-"""Provides an abstraction for obtaining database schema information.
-
-Usage Notes:
-
-Here are some general conventions when accessing the low level inspector
-methods such as get_table_names, get_columns, etc.
-
-1. Inspector methods return lists of dicts in most cases for the following
-   reasons:
-
-   * They're both standard types that can be serialized.
-   * Using a dict instead of a tuple allows easy expansion of attributes.
-   * Using a list for the outer structure maintains order and is easy to work
-     with (e.g. list comprehension [d['name'] for d in cols]).
-
-2. Records that contain a name, such as the column name in a column record
-   use the key 'name'. So for most return values, each record will have a
-   'name' attribute..

-             all dialects.  In particular, most DBAPIs do not support an

-"""Attribute implementation for _Dispatch classes.
-
-The various listener targets for a particular event class are represented
-as attributes, which refer to collections of listeners to be fired off.
-These collections can exist at the class level as well as at the instance
-level.  An event is fired off using code like this::
-
-    some_object.dispatch.first_connect(arg1, arg2)
-
-Above, ``some_object.dispatch`` would be an instance of ``_Dispatch`` and
-``first_connect`` is typically an instance of ``_ListenerCollection``
-if event listeners are present, or ``_EmptyListener`` if none are present.
-
-The attribute mechanics here spend effort trying to ensure listener functions
-are available with a minimum of function call overhead, that unnecessary
-objects aren't created (i.e. many empty per-instance listener collections),
-as well as that everything is garbage collectable when owning references are
-lost.  Other features such as "propagation" of listener functions across
-many ``_Dispatch`` instances, "joining" of multiple ``_Dispatch`` instances,
-as well as support for subclass propagation (e.g. events assigned to
-``Pool`` vs. ``QueuePool``) are all implemented here.

-    Define event listeners for schema objects,
-    that is, :class:`.SchemaItem` and other :class:`.SchemaEventTarget`
-    subclasses, including :class:`.MetaData`, :class:`.Table`,
-    :class:`.Column`.
-
-    :class:`.MetaData` and :class:`.Table` support events
-    specifically regarding when CREATE and DROP
-    DDL is emitted to the database.
-
-    Attachment events are also provided to customize
-    behavior whenever a child schema element is associated
-    with a parent, such as, when a :class:`.Column` is associated
-    with its :class:`.Table`, when a :class:`.ForeignKeyConstraint`
-    is associated with a :class:`.Table`, etc.
-
-    Example using the ``after_create`` event::
-
-        from sqlalchemy import event
-        from sqlalchemy import Table, Column, Metadata, Integer
-
-        m = MetaData()
-        some_table = Table('some_table', m, Column('data', Integer))

-
-        event.listen(some_table, "after_create", after_create)
-
-    DDL events integrate closely with the
-    :class:`.DDL` class and the :class:`.DDLElement` hierarchy
-    of DDL clause constructs, which are themselves appropriate
-    as listener callables::
-

-    target.
-
-    The returned value is an instance of :class:`.AssociationProxy`.
-
-    Implements a Python property representing a relationship as a collection
-    of simpler values, or a scalar value.  The proxied property will mimic
-    the collection type of the target (list, dict or set), or, in the case of
-    a one to one relationship, a simple scalar value.
-
-    :param target_collection: Name of the attribute we'll proxy to.
-      This attribute is typically mapped by
-      :func:`~sqlalchemy.orm.relationship` to link to a target collection, but
-      can also be a many-to-one or non-scalar relationship.
-
-    :param attr: Attribute on the associated instance or instances we'll
-      proxy for.
-
-      For example, given a target collection of [obj1, obj2], a list created

-      the 'value' for the new instance.  For dict types, two arguments are
-      passed: key and value.
-
-      If you want to construct instances differently, supply a *creator*
-      function that takes arguments as above and returns instances.
-
-      For scalar relationships, creator() will be called if the target is None.
-      If the target is present, set operations are proxied to setattr() on the
-      associated object.
-
-      If you have an associated object with multiple attributes, you may set
-      up multiple association proxies mapping to different attributes.  See
-      the unit tests for examples, and for examples of how creator() functions
-      can be used to construct the scalar relationship on-demand in this

-"""Define an extension to the :mod:`sqlalchemy.ext.declarative` system
-which automatically generates mapped classes and relationships from a database
-schema, typically though not necessarily one which is reflected.
-
-.. versionadded:: 0.9.1 Added :mod:`sqlalchemy.ext.automap`.
-
-.. note::
-
-    The :mod:`sqlalchemy.ext.automap` extension should be considered
-    **experimental** as of 0.9.1.   Featureset and API stability is
-    not guaranteed at this time.
-
-It is hoped that the :class:`.AutomapBase` system provides a quick
-and modernized solution to the problem that the very famous
-`SQLSoup <https://sqlsoup.readthedocs.org/en/latest/>`_
-also tries to solve, that of generating a quick and rudimentary object
-model from an existing database on the fly.  By addressing the issue strictly
-at the mapper configuration level, and integrating fully with existing
-Declarative class techniques, :class:`.AutomapBase` seeks to provide
-a well-integrated approach to the issue of expediently auto-generating ad-hoc
-mappings.
-
-
-Basic Use
-=========
-
-The simplest usage is to reflect an existing database into a new model.
-We create a new :class:`.AutomapBase` class in a similar manner as to how
-we create a declarative base class, using :func:`.automap_base`.
-We then call :meth:`.AutomapBase.prepare` on the resulting base class,
-asking it to reflect the schema and produce mappings::
-
-    from sqlalchemy.ext.automap import automap_base
-    from sqlalchemy.orm import Session
-    from sqlalchemy import create_engine
-
-    Base = automap_base()
-
-    # engine, suppose it has two tables 'user' and 'address' set up
-    engine = create_engine("sqlite:///mydatabase.db")
-
-    # reflect the tables
-    Base.prepare(engine, reflect=True)
-
-    # mapped classes are now created with names by default
-    # matching that of the table name.
-    User = Base.classes.user
-    Address = Base.classes.address
-
-    session = Session(engine)
-
-    # rudimentary relationships are produced
-    session.add(Address(email_address="foo@bar.com", user=User(name="foo")))
-    session.commit()
-
-    # collection-based relationships are by default named "<classname>_collection"
-    print (u1.address_collection)
-
-Above, calling :meth:`.AutomapBase.prepare` while passing along the
-:paramref:`.AutomapBase.prepare.reflect` parameter indicates that the
-:meth:`.MetaData.reflect` method will be called on this declarative base
-classes' :class:`.MetaData` collection; then, each viable
-:class:`.Table` within the :class:`.MetaData` will get a new mapped class
-generated automatically.  The :class:`.ForeignKeyConstraint` objects which
-link the various tables together will be used to produce new, bidirectional
-:func:`.relationship` objects between classes.   The classes and relationships
-follow along a default naming scheme that we can customize.  At this point,
-our basic mapping consisting of related ``User`` and ``Address`` classes is ready
-to use in the traditional way.
-
-Generating Mappings from an Existing MetaData
-=============================================
-
-We can pass a pre-declared :class:`.MetaData` object to :func:`.automap_base`.
-This object can be constructed in any way, including programmatically, from
-a serialized file, or from itself being reflected using :meth:`.MetaData.reflect`.
-Below we illustrate a combination of reflection and explicit table declaration::
-
-    from sqlalchemy import create_engine, MetaData, Table, Column, ForeignKey
-    engine = create_engine("sqlite:///mydatabase.db")
-
-    # produce our own MetaData object
-    metadata = MetaData()
-
-    # we can reflect it ourselves from a database, using options
-    # such as 'only' to limit what tables we look at...
-    metadata.reflect(engine, only=['user', 'address'])
-
-    # ... or just define our own Table objects with it (or combine both)
-    Table('user_order', metadata,
-                    Column('id', Integer, primary_key=True),
-                    Column('user_id', ForeignKey('user.id'))
-                )
-
-    # we can then produce a set of mappings from this MetaData.
-    Base = automap_base(metadata=metadata)
-
-    # calling prepare() just sets up mapped classes and relationships.
-    Base.prepare()
-
-    # mapped classes are ready
-    User, Address, Order = Base.classes.user, Base.classes.address, Base.classes.user_order
-
-Specifying Classes Explcitly
-============================
-
-The :mod:`.sqlalchemy.ext.automap` extension allows classes to be defined
-explicitly, in a way similar to that of the :class:`.DeferredReflection` class.
-Classes that extend from :class:`.AutomapBase` act like regular declarative
-classes, but are not immediately mapped after their construction, and are instead
-mapped when we call :meth:`.AutomapBase.prepare`.  The :meth:`.AutomapBase.prepare`
-method will make use of the classes we've established based on the table name
-we use.  If our schema contains tables ``user`` and ``address``, we can define
-one or both of the classes to be used::
-
-    from sqlalchemy.ext.automap import automap_base
-    from sqlalchemy import create_engine
-
-    # automap base
-    Base = automap_base()
-
-    # pre-declare User for the 'user' table
-    class User(Base):
-        __tablename__ = 'user'
-
-        # override schema elements like Columns
-        user_name = Column('name', String)
-
-        # override relationships too, if desired.
-        # we must use the same name that automap would use for the relationship,
-        # and also must refer to the class name that automap will generate
-        # for "address"
-        address_collection = relationship("address", collection_class=set)
-
-    # reflect
-    engine = create_engine("sqlite:///mydatabase.db")
-    Base.prepare(engine, reflect=True)
-
-    # we still have Address generated from the tablename "address",
-    # but User is the same as Base.classes.User now
-
-    Address = Base.classes.address
-
-    u1 = session.query(User).first()
-    print (u1.address_collection)
-
-    # the backref is still there:
-    a1 = session.query(Address).first()
-    print (a1.user)
-
-Above, one of the more intricate details is that we illustrated overriding
-one of the :func:`.relationship` objects that automap would have created.
-To do this, we needed to make sure the names match up with what automap
-would normally generate, in that the relationship name would be ``User.address_collection``
-and the name of the class referred to, from automap's perspective, is called
-``address``, even though we are referring to it as ``Address`` within our usage
-of this class.
-
-Overriding Naming Schemes
-=========================
-
-:mod:`.sqlalchemy.ext.automap` is tasked with producing mapped classes and
-relationship names based on a schema, which means it has decision points in how
-these names are determined.  These three decision points are provided using
-functions which can be passed to the :meth:`.AutomapBase.prepare` method, and
-are known as :func:`.classname_for_table`,
-:func:`.name_for_scalar_relationship`,
-and :func:`.name_for_collection_relationship`.  Any or all of these
-functions are provided as in the example below, where we use a "camel case"
-scheme for class names and a "pluralizer" for collection names using the
-`Inflect <https://pypi.python.org/pypi/inflect>`_ package::
-
-    import re
-    import inflect
-
-    def camelize_classname(base, tablename, table):
-        "Produce a 'camelized' class name, e.g. "
-        "'words_and_underscores' -> 'WordsAndUnderscores'"
-
-        return str(tablename[0].upper() + \\
-                re.sub(r'_(\w)', lambda m: m.group(1).upper(), tablename[1:]))
-
-    _pluralizer = inflect.engine()
-    def pluralize_collection(base, local_cls, referred_cls, constraint):
-        "Produce an 'uncamelized', 'pluralized' class name, e.g. "
-        "'SomeTerm' -> 'some_terms'"
-
-        referred_name = referred_cls.__name__
-        uncamelized = referred_name[0].lower() + \\
-                        re.sub(r'\W',
-                                lambda m: "_%s" % m.group(0).lower(),
-                                referred_name[1:])
-        pluralized = _pluralizer.plural(uncamelized)
-        return pluralized
-
-    from sqlalchemy.ext.automap import automap_base
-
-    Base = automap_base()
-
-    engine = create_engine("sqlite:///mydatabase.db")
-
-    Base.prepare(engine, reflect=True,
-                classname_for_table=camelize_classname,
-                name_for_collection_relationship=pluralize_collection
-        )
-
-From the above mapping, we would now have classes ``User`` and ``Address``,
-where the collection from ``User`` to ``Address`` is called ``User.addresses``::
-

-Relationship Detection
-======================
-
-The vast majority of what automap accomplishes is the generation of
-:func:`.relationship` structures based on foreign keys.  The mechanism
-by which this works for many-to-one and one-to-many relationships is as follows:
-
-1. A given :class:`.Table`, known to be mapped to a particular class,
-   is examined for :class:`.ForeignKeyConstraint` objects.
-
-2. From each :class:`.ForeignKeyConstraint`, the remote :class:`.Table`
-   object present is matched up to the class to which it is to be mapped,
-   if any, else it is skipped.
-
-3. As the :class:`.ForeignKeyConstraint` we are examining correponds to a reference
-   from the immediate mapped class,
-   the relationship will be set up as a many-to-one referring to the referred class;
-   a corresponding one-to-many backref will be created on the referred class referring
-   to this class.
-
-4. The names of the relationships are determined using the
-   :paramref:`.AutomapBase.prepare.name_for_scalar_relationship` and
-   :paramref:`.AutomapBase.prepare.name_for_collection_relationship`
-   callable functions.  It is important to note that the default relationship
-   naming derives the name from the **the actual class name**.  If you've
-   given a particular class an explicit name by declaring it, or specified an
-   alternate class naming scheme, that's the name from which the relationship
-   name will be derived.
-
-5. The classes are inspected for an existing mapped property matching these
-   names.  If one is detected on one side, but none on the other side, :class:`.AutomapBase`
-   attempts to create a relationship on the missing side, then uses the
-   :paramref:`.relationship.back_populates` parameter in order to point
-   the new relationship to the other side.
-
-6. In the usual case where no relationship is on either side,
-   :meth:`.AutomapBase.prepare` produces a :func:`.relationship` on the "many-to-one"
-   side and matches it to the other using the :paramref:`.relationship.backref`
-   parameter.
-
-7. Production of the :func:`.relationship` and optionally the :func:`.backref`
-   is handed off to the :paramref:`.AutomapBase.prepare.generate_relationship`
-   function, which can be supplied by the end-user in order to augment
-   the arguments passed to :func:`.relationship` or :func:`.backref` or to
-   make use of custom implementations of these functions.
-
-Custom Relationship Arguments
------------------------------
-
-The :paramref:`.AutomapBase.prepare.generate_relationship` hook can be used
-to add parameters to relationships.  For most cases, we can make use of the
-existing :func:`.automap.generate_relationship` function to return
-the object, after augmenting the given keyword dictionary with our own
-arguments.
-
-Below is an illustration of how to send
-:paramref:`.relationship.cascade` and
-:paramref:`.relationship.passive_deletes`
-options along to all one-to-many relationships::
-
-    from sqlalchemy.ext.automap import generate_relationship
-
-    def _gen_relationship(base, direction, return_fn,
-                                    attrname, local_cls, referred_cls, **kw):
-        if direction is interfaces.ONETOMANY:
-            kw['cascade'] = 'all, delete-orphan'
-            kw['passive_deletes'] = True
-        # make use of the built-in function to actually return
-        # the result.
-        return generate_relationship(base, direction, return_fn,
-                                        attrname, local_cls, referred_cls, **kw)
-
-    from sqlalchemy.ext.automap import automap_base
-    from sqlalchemy import create_engine
-
-    # automap base
-    Base = automap_base()
-
-    engine = create_engine("sqlite:///mydatabase.db")
-    Base.prepare(engine, reflect=True,
-                generate_relationship=_gen_relationship)
-
-Many-to-Many relationships
---------------------------
-
-:mod:`.sqlalchemy.ext.automap` will generate many-to-many relationships, e.g.
-those which contain a ``secondary`` argument.  The process for producing these
-is as follows:
-
-1. A given :class:`.Table` is examined for :class:`.ForeignKeyConstraint` objects,
-   before any mapped class has been assigned to it.
-
-2. If the table contains two and exactly two :class:`.ForeignKeyConstraint`
-   objects, and all columns within this table are members of these two
-   :class:`.ForeignKeyConstraint` objects, the table is assumed to be a
-   "secondary" table, and will **not be mapped directly**.
-
-3. The two (or one, for self-referential) external tables to which the :class:`.Table`
-   refers to are matched to the classes to which they will be mapped, if any.
-
-4. If mapped classes for both sides are located, a many-to-many bi-directional
-   :func:`.relationship` / :func:`.backref` pair is created between the two
-   classes.
-
-5. The override logic for many-to-many works the same as that of one-to-many/
-   many-to-one; the :func:`.generate_relationship` function is called upon
-   to generate the strucures and existing attributes will be maintained.
-
-Relationships with Inheritance
-------------------------------
-
-:mod:`.sqlalchemy.ext.automap` will not generate any relationships between
-two classes that are in an inheritance relationship.   That is, with two classes
-given as follows::
-
-    class Employee(Base):
-        __tablename__ = 'employee'
-        id = Column(Integer, primary_key=True)
-        type = Column(String(50))
-        __mapper_args__ = {
-             'polymorphic_identity':'employee', 'polymorphic_on': type
-        }
-
-    class Engineer(Employee):
-        __tablename__ = 'engineer'
-        id = Column(Integer, ForeignKey('employee.id'), primary_key=True)
-        __mapper_args__ = {
-            'polymorphic_identity':'engineer',
-        }
-
-The foreign key from ``Engineer`` to ``Employee`` is used not for a relationship,
-but to establish joined inheritance between the two classes.
-
-Note that this means automap will not generate *any* relationships
-for foreign keys that link from a subclass to a superclass.  If a mapping
-has actual relationships from subclass to superclass as well, those
-need to be explicit.  Below, as we have two separate foreign keys
-from ``Engineer`` to ``Employee``, we need to set up both the relationship
-we want as well as the ``inherit_condition``, as these are not things
-SQLAlchemy can guess::
-
-    class Employee(Base):
-        __tablename__ = 'employee'
-        id = Column(Integer, primary_key=True)
-        type = Column(String(50))
-
-        __mapper_args__ = {
-            'polymorphic_identity':'employee', 'polymorphic_on':type
-        }
-
-    class Engineer(Employee):
-        __tablename__ = 'engineer'
-        id = Column(Integer, ForeignKey('employee.id'), primary_key=True)
-        favorite_employee_id = Column(Integer, ForeignKey('employee.id'))
-
-        favorite_employee = relationship(Employee, foreign_keys=favorite_employee_id)
-
-        __mapper_args__ = {
-            'polymorphic_identity':'engineer',
-            'inherit_condition': id == Employee.id
-        }
-
-
-Using Automap with Explicit Declarations
-========================================
-
-As noted previously, automap has no dependency on reflection, and can make
-use of any collection of :class:`.Table` objects within a :class:`.MetaData`
-collection.  From this, it follows that automap can also be used
-generate missing relationships given an otherwise complete model that fully defines
-table metadata::
-
-    from sqlalchemy.ext.automap import automap_base
-    from sqlalchemy import Column, Integer, String, ForeignKey
-
-    Base = automap_base()
-
-    class User(Base):
-        __tablename__ = 'user'
-
-        id = Column(Integer, primary_key=True)
-        name = Column(String)
-
-    class Address(Base):
-        __tablename__ = 'address'
-
-        id = Column(Integer, primary_key=True)
-        email = Column(String)
-        user_id = Column(ForeignKey('user.id'))
-
-    # produce relationships
-    Base.prepare()
-
-    # mapping is complete, with "address_collection" and
-    # "user" relationships
-    a1 = Address(email='u1')
-    a2 = Address(email='u2')
-    u1 = User(address_collection=[a1, a2])
-    assert a1.user is u1
-
-Above, given mostly complete ``User`` and ``Address`` mappings, the
-:class:`.ForeignKey` which we defined on ``Address.user_id`` allowed a
-bidirectional relationship pair ``Address.user`` and ``User.address_collection``
-to be generated on the mapped classes.
-
-Note that when subclassing :class:`.AutomapBase`, the :meth:`.AutomapBase.prepare`
-method is required; if not called, the classes we've declared are in an
-un-mapped state.

-"""Provides an API for creation of custom ClauseElements and compilers.
-
-Synopsis
-========
-
-Usage involves the creation of one or more
-:class:`~sqlalchemy.sql.expression.ClauseElement` subclasses and one or
-more callables defining its compilation::
-
-    from sqlalchemy.ext.compiler import compiles
-    from sqlalchemy.sql.expression import ColumnClause
-
-    class MyColumn(ColumnClause):
-        pass
-
-    @compiles(MyColumn)
-    def compile_mycolumn(element, compiler, **kw):
-        return "[%s]" % element.name
-
-Above, ``MyColumn`` extends :class:`~sqlalchemy.sql.expression.ColumnClause`,
-the base expression element for named column objects. The ``compiles``
-decorator registers itself with the ``MyColumn`` class so that it is invoked
-when the object is compiled to a string::
-
-    from sqlalchemy import select
-
-    s = select([MyColumn('x'), MyColumn('y')])
-    print str(s)
-
-Produces::
-
-    SELECT [x], [y]
-
-Dialect-specific compilation rules
-==================================
-
-Compilers can also be made dialect-specific. The appropriate compiler will be
-invoked for the dialect in use::
-
-    from sqlalchemy.schema import DDLElement
-
-    class AlterColumn(DDLElement):
-
-        def __init__(self, column, cmd):
-            self.column = column
-            self.cmd = cmd
-
-    @compiles(AlterColumn)
-    def visit_alter_column(element, compiler, **kw):
-        return "ALTER COLUMN %s ..." % element.column.name
-
-    @compiles(AlterColumn, 'postgresql')
-    def visit_alter_column(element, compiler, **kw):
-        return "ALTER TABLE %s ALTER COLUMN %s ..." % (element.table.name, element.column.name)
-
-The second ``visit_alter_table`` will be invoked when any ``postgresql``
-dialect is used.
-
-Compiling sub-elements of a custom expression construct
-=======================================================
-
-The ``compiler`` argument is the
-:class:`~sqlalchemy.engine.interfaces.Compiled` object in use. This object
-can be inspected for any information about the in-progress compilation,
-including ``compiler.dialect``, ``compiler.statement`` etc. The
-:class:`~sqlalchemy.sql.compiler.SQLCompiler` and
-:class:`~sqlalchemy.sql.compiler.DDLCompiler` both include a ``process()``
-method which can be used for compilation of embedded attributes::
-
-    from sqlalchemy.sql.expression import Executable, ClauseElement
-
-    class InsertFromSelect(Executable, ClauseElement):
-        def __init__(self, table, select):
-            self.table = table
-            self.select = select
-
-    @compiles(InsertFromSelect)
-    def visit_insert_from_select(element, compiler, **kw):
-        return "INSERT INTO %s (%s)" % (
-            compiler.process(element.table, asfrom=True),
-            compiler.process(element.select)
-        )
-
-    insert = InsertFromSelect(t1, select([t1]).where(t1.c.x>5))
-    print insert
-
-Produces::
-
-    "INSERT INTO mytable (SELECT mytable.x, mytable.y, mytable.z FROM mytable WHERE mytable.x > :x_1)"
-
-.. note::
-
-    The above ``InsertFromSelect`` construct is only an example, this actual
-    functionality is already available using the
-    :meth:`.Insert.from_select` method.
-
-.. note::
-
-   The above ``InsertFromSelect`` construct probably wants to have "autocommit"
-   enabled.  See :ref:`enabling_compiled_autocommit` for this step.
-
-Cross Compiling between SQL and DDL compilers
----------------------------------------------
-
-SQL and DDL constructs are each compiled using different base compilers -
-``SQLCompiler`` and ``DDLCompiler``.   A common need is to access the
-compilation rules of SQL expressions from within a DDL expression. The
-``DDLCompiler`` includes an accessor ``sql_compiler`` for this reason, such as
-below where we generate a CHECK constraint that embeds a SQL expression::
-
-    @compiles(MyConstraint)
-    def compile_my_constraint(constraint, ddlcompiler, **kw):
-        return "CONSTRAINT %s CHECK (%s)" % (
-            constraint.name,
-            ddlcompiler.sql_compiler.process(constraint.expression)
-        )
-
-.. _enabling_compiled_autocommit:
-
-Enabling Autocommit on a Construct
-==================================
-
-Recall from the section :ref:`autocommit` that the :class:`.Engine`, when
-asked to execute a construct in the absence of a user-defined transaction,
-detects if the given construct represents DML or DDL, that is, a data
-modification or data definition statement, which requires (or may require,
-in the case of DDL) that the transaction generated by the DBAPI be committed
-(recall that DBAPI always has a transaction going on regardless of what
-SQLAlchemy does).   Checking for this is actually accomplished by checking for
-the "autocommit" execution option on the construct.    When building a
-construct like an INSERT derivation, a new DDL type, or perhaps a stored
-procedure that alters data, the "autocommit" option needs to be set in order
-for the statement to function with "connectionless" execution
-(as described in :ref:`dbengine_implicit`).
-
-Currently a quick way to do this is to subclass :class:`.Executable`, then
-add the "autocommit" flag to the ``_execution_options`` dictionary (note this
-is a "frozen" dictionary which supplies a generative ``union()`` method)::
-
-    from sqlalchemy.sql.expression import Executable, ClauseElement
-
-    class MyInsertThing(Executable, ClauseElement):
-        _execution_options = \\
-            Executable._execution_options.union({'autocommit': True})
-
-More succinctly, if the construct is truly similar to an INSERT, UPDATE, or
-DELETE, :class:`.UpdateBase` can be used, which already is a subclass
-of :class:`.Executable`, :class:`.ClauseElement` and includes the
-``autocommit`` flag::
-
-    from sqlalchemy.sql.expression import UpdateBase
-
-    class MyInsertThing(UpdateBase):
-        def __init__(self, ...):
-            ...
-
-
-
-
-DDL elements that subclass :class:`.DDLElement` already have the
-"autocommit" flag turned on.
-
-
-
-
-Changing the default compilation of existing constructs
-=======================================================
-
-The compiler extension applies just as well to the existing constructs.  When
-overriding the compilation of a built in SQL construct, the @compiles
-decorator is invoked upon the appropriate class (be sure to use the class,
-i.e. ``Insert`` or ``Select``, instead of the creation function such
-as ``insert()`` or ``select()``).
-
-Within the new compilation function, to get at the "original" compilation
-routine, use the appropriate visit_XXX method - this
-because compiler.process() will call upon the overriding routine and cause
-an endless loop.   Such as, to add "prefix" to all insert statements::
-
-    from sqlalchemy.sql.expression import Insert
-
-    @compiles(Insert)
-    def prefix_inserts(insert, compiler, **kw):
-        return compiler.visit_insert(insert.prefix_with("some prefix"), **kw)
-
-The above compiler will prefix all INSERT statements with "some prefix" when
-compiled.
-
-.. _type_compilation_extension:
-
-Changing Compilation of Types
-=============================
-
-``compiler`` works for types, too, such as below where we implement the
-MS-SQL specific 'max' keyword for ``String``/``VARCHAR``::
-
-    @compiles(String, 'mssql')
-    @compiles(VARCHAR, 'mssql')
-    def compile_varchar(element, compiler, **kw):
-        if element.length == 'max':
-            return "VARCHAR('max')"
-        else:
-            return compiler.visit_VARCHAR(element, **kw)
-
-    foo = Table('foo', metadata,
-        Column('data', VARCHAR('max'))
-    )
-
-Subclassing Guidelines
-======================
-
-A big part of using the compiler extension is subclassing SQLAlchemy
-expression constructs. To make this easier, the expression and
-schema packages feature a set of "bases" intended for common tasks.
-A synopsis is as follows:
-
-* :class:`~sqlalchemy.sql.expression.ClauseElement` - This is the root
-  expression class. Any SQL expression can be derived from this base, and is
-  probably the best choice for longer constructs such as specialized INSERT
-  statements.
-
-* :class:`~sqlalchemy.sql.expression.ColumnElement` - The root of all
-  "column-like" elements. Anything that you'd place in the "columns" clause of
-  a SELECT statement (as well as order by and group by) can derive from this -
-  the object will automatically have Python "comparison" behavior.
-
-  :class:`~sqlalchemy.sql.expression.ColumnElement` classes want to have a
-  ``type`` member which is expression's return type.  This can be established
-  at the instance level in the constructor, or at the class level if its
-  generally constant::
-
-      class timestamp(ColumnElement):
-          type = TIMESTAMP()
-
-* :class:`~sqlalchemy.sql.functions.FunctionElement` - This is a hybrid of a
-  ``ColumnElement`` and a "from clause" like object, and represents a SQL
-  function or stored procedure type of call. Since most databases support
-  statements along the line of "SELECT FROM <some function>"
-  ``FunctionElement`` adds in the ability to be used in the FROM clause of a
-  ``select()`` construct::
-
-      from sqlalchemy.sql.expression import FunctionElement
-
-      class coalesce(FunctionElement):
-          name = 'coalesce'
-
-      @compiles(coalesce)
-      def compile(element, compiler, **kw):
-          return "coalesce(%s)" % compiler.process(element.clauses)
-
-      @compiles(coalesce, 'oracle')
-      def compile(element, compiler, **kw):
-          if len(element.clauses) > 2:
-              raise TypeError("coalesce only supports two arguments on Oracle")
-          return "nvl(%s)" % compiler.process(element.clauses)
-
-* :class:`~sqlalchemy.schema.DDLElement` - The root of all DDL expressions,
-  like CREATE TABLE, ALTER TABLE, etc. Compilation of ``DDLElement``
-  subclasses is issued by a ``DDLCompiler`` instead of a ``SQLCompiler``.
-  ``DDLElement`` also features ``Table`` and ``MetaData`` event hooks via the
-  ``execute_at()`` method, allowing the construct to be invoked during CREATE
-  TABLE and DROP TABLE sequences.
-
-* :class:`~sqlalchemy.sql.expression.Executable` - This is a mixin which
-  should be used with any expression class that represents a "standalone"
-  SQL statement that can be passed directly to an ``execute()`` method.  It
-  is already implicit within ``DDLElement`` and ``FunctionElement``.
-
-Further Examples
-================
-
-"UTC timestamp" function
--------------------------
-
-A function that works like "CURRENT_TIMESTAMP" except applies the
-appropriate conversions so that the time is in UTC time.   Timestamps are best
-stored in relational databases as UTC, without time zones.   UTC so that your
-database doesn't think time has gone backwards in the hour when daylight
-savings ends, without timezones because timezones are like character
-encodings - they're best applied only at the endpoints of an application
-(i.e. convert to UTC upon user input, re-apply desired timezone upon display).
-
-For Postgresql and Microsoft SQL Server::
-
-    from sqlalchemy.sql import expression
-    from sqlalchemy.ext.compiler import compiles
-    from sqlalchemy.types import DateTime
-
-    class utcnow(expression.FunctionElement):
-        type = DateTime()
-
-    @compiles(utcnow, 'postgresql')
-    def pg_utcnow(element, compiler, **kw):
-        return "TIMEZONE('utc', CURRENT_TIMESTAMP)"
-
-    @compiles(utcnow, 'mssql')
-    def ms_utcnow(element, compiler, **kw):
-        return "GETUTCDATE()"
-
-Example usage::
-
-    from sqlalchemy import (
-                Table, Column, Integer, String, DateTime, MetaData
-            )
-    metadata = MetaData()
-    event = Table("event", metadata,
-        Column("id", Integer, primary_key=True),
-        Column("description", String(50), nullable=False),
-        Column("timestamp", DateTime, server_default=utcnow())
-    )
-
-"GREATEST" function
--------------------
-
-The "GREATEST" function is given any number of arguments and returns the one
-that is of the highest value - it's equivalent to Python's ``max``
-function.  A SQL standard version versus a CASE based version which only
-accommodates two arguments::
-
-    from sqlalchemy.sql import expression
-    from sqlalchemy.ext.compiler import compiles
-    from sqlalchemy.types import Numeric
-
-    class greatest(expression.FunctionElement):
-        type = Numeric()
-        name = 'greatest'
-
-    @compiles(greatest)
-    def default_greatest(element, compiler, **kw):
-        return compiler.visit_function(element)
-
-    @compiles(greatest, 'sqlite')
-    @compiles(greatest, 'mssql')
-    @compiles(greatest, 'oracle')
-    def case_greatest(element, compiler, **kw):
-        arg1, arg2 = list(element.clauses)
-        return "CASE WHEN %s > %s THEN %s ELSE %s END" % (
-            compiler.process(arg1),
-            compiler.process(arg2),
-            compiler.process(arg1),
-            compiler.process(arg2),
-        )
-
-Example usage::
-
-    Session.query(Account).\\
-            filter(
-                greatest(
-                    Account.checking_balance,
-                    Account.savings_balance) > 10000
-            )
-
-"false" expression
-------------------
-
-Render a "false" constant expression, rendering as "0" on platforms that
-don't have a "false" constant::
-
-    from sqlalchemy.sql import expression
-    from sqlalchemy.ext.compiler import compiles
-
-    class sql_false(expression.ColumnElement):
-        pass
-
-    @compiles(sql_false)
-    def default_false(element, compiler, **kw):
-        return "false"
-
-    @compiles(sql_false, 'mssql')
-    @compiles(sql_false, 'mysql')
-    @compiles(sql_false, 'oracle')
-    def int_false(element, compiler, **kw):
-        return "0"
-
-Example usage::
-
-    from sqlalchemy import select, union_all
-
-    exp = union_all(
-        select([users.c.name, sql_false().label("enrolled")]),
-        select([customers.c.name, customers.c.enrolled])
-    )

-Synopsis
-========
-
-SQLAlchemy object-relational configuration involves the
-combination of :class:`.Table`, :func:`.mapper`, and class
-objects to define a mapped class.
-:mod:`~sqlalchemy.ext.declarative` allows all three to be
-expressed at once within the class declaration. As much as
-possible, regular SQLAlchemy schema and ORM constructs are
-used directly, so that configuration between "classical" ORM
-usage and declarative remain highly similar.
-
-As a simple example::
-
-    from sqlalchemy.ext.declarative import declarative_base
-
-    Base = declarative_base()
-
-    class SomeClass(Base):
-        __tablename__ = 'some_table'
-        id = Column(Integer, primary_key=True)
-        name =  Column(String(50))
-
-Above, the :func:`declarative_base` callable returns a new base class from
-which all mapped classes should inherit. When the class definition is
-completed, a new :class:`.Table` and :func:`.mapper` will have been generated.
-
-The resulting table and mapper are accessible via
-``__table__`` and ``__mapper__`` attributes on the
-``SomeClass`` class::
-
-    # access the mapped Table
-    SomeClass.__table__
-
-    # access the Mapper
-    SomeClass.__mapper__
-
-Defining Attributes
-===================
-
-In the previous example, the :class:`.Column` objects are
-automatically named with the name of the attribute to which they are
-assigned.
-
-To name columns explicitly with a name distinct from their mapped attribute,
-just give the column a name.  Below, column "some_table_id" is mapped to the
-"id" attribute of `SomeClass`, but in SQL will be represented as
-"some_table_id"::
-
-    class SomeClass(Base):
-        __tablename__ = 'some_table'
-        id = Column("some_table_id", Integer, primary_key=True)
-
-Attributes may be added to the class after its construction, and they will be
-added to the underlying :class:`.Table` and
-:func:`.mapper` definitions as appropriate::
-
-    SomeClass.data = Column('data', Unicode)
-    SomeClass.related = relationship(RelatedInfo)
-
-Classes which are constructed using declarative can interact freely
-with classes that are mapped explicitly with :func:`.mapper`.
-
-It is recommended, though not required, that all tables
-share the same underlying :class:`~sqlalchemy.schema.MetaData` object,
-so that string-configured :class:`~sqlalchemy.schema.ForeignKey`
-references can be resolved without issue.
-
-Accessing the MetaData
-=======================
-
-The :func:`declarative_base` base class contains a
-:class:`.MetaData` object where newly defined
-:class:`.Table` objects are collected. This object is
-intended to be accessed directly for
-:class:`.MetaData`-specific operations. Such as, to issue
-CREATE statements for all tables::
-
-    engine = create_engine('sqlite://')
-    Base.metadata.create_all(engine)
-
-:func:`declarative_base` can also receive a pre-existing
-:class:`.MetaData` object, which allows a
-declarative setup to be associated with an already
-existing traditional collection of :class:`~sqlalchemy.schema.Table`
-objects::
-
-    mymetadata = MetaData()
-    Base = declarative_base(metadata=mymetadata)
-
-
-.. _declarative_configuring_relationships:
-
-Configuring Relationships
-=========================
-
-Relationships to other classes are done in the usual way, with the added
-feature that the class specified to :func:`~sqlalchemy.orm.relationship`
-may be a string name.  The "class registry" associated with ``Base``
-is used at mapper compilation time to resolve the name into the actual
-class object, which is expected to have been defined once the mapper
-configuration is used::
-
-    class User(Base):
-        __tablename__ = 'users'
-
-        id = Column(Integer, primary_key=True)
-        name = Column(String(50))
-        addresses = relationship("Address", backref="user")
-
-    class Address(Base):
-        __tablename__ = 'addresses'
-
-        id = Column(Integer, primary_key=True)
-        email = Column(String(50))
-        user_id = Column(Integer, ForeignKey('users.id'))
-
-Column constructs, since they are just that, are immediately usable,
-as below where we define a primary join condition on the ``Address``
-class using them::
-
-    class Address(Base):
-        __tablename__ = 'addresses'
-
-        id = Column(Integer, primary_key=True)
-        email = Column(String(50))
-        user_id = Column(Integer, ForeignKey('users.id'))
-        user = relationship(User, primaryjoin=user_id == User.id)
-
-In addition to the main argument for :func:`~sqlalchemy.orm.relationship`,
-other arguments which depend upon the columns present on an as-yet
-undefined class may also be specified as strings.  These strings are
-evaluated as Python expressions.  The full namespace available within
-this evaluation includes all classes mapped for this declarative base,
-as well as the contents of the ``sqlalchemy`` package, including
-expression functions like :func:`~sqlalchemy.sql.expression.desc` and
-:attr:`~sqlalchemy.sql.expression.func`::
-
-    class User(Base):
-        # ....
-        addresses = relationship("Address",
-                             order_by="desc(Address.email)",
-                             primaryjoin="Address.user_id==User.id")
-
-For the case where more than one module contains a class of the same name,
-string class names can also be specified as module-qualified paths
-within any of these string expressions::
-
-    class User(Base):
-        # ....
-        addresses = relationship("myapp.model.address.Address",
-                             order_by="desc(myapp.model.address.Address.email)",
-                             primaryjoin="myapp.model.address.Address.user_id=="
-                                            "myapp.model.user.User.id")
-
-The qualified path can be any partial path that removes ambiguity between
-the names.  For example, to disambiguate between
-``myapp.model.address.Address`` and ``myapp.model.lookup.Address``,
-we can specify ``address.Address`` or ``lookup.Address``::
-
-    class User(Base):
-        # ....
-        addresses = relationship("address.Address",
-                             order_by="desc(address.Address.email)",
-                             primaryjoin="address.Address.user_id=="
-                                            "User.id")
-
-.. versionadded:: 0.8
-   module-qualified paths can be used when specifying string arguments
-   with Declarative, in order to specify specific modules.
-
-Two alternatives also exist to using string-based attributes.  A lambda
-can also be used, which will be evaluated after all mappers have been
-configured::
-
-    class User(Base):
-        # ...
-        addresses = relationship(lambda: Address,
-                             order_by=lambda: desc(Address.email),
-                             primaryjoin=lambda: Address.user_id==User.id)
-
-Or, the relationship can be added to the class explicitly after the classes
-are available::
-
-    User.addresses = relationship(Address,
-                              primaryjoin=Address.user_id==User.id)
-
-
-
-.. _declarative_many_to_many:
-
-Configuring Many-to-Many Relationships
-======================================
-
-Many-to-many relationships are also declared in the same way
-with declarative as with traditional mappings. The
-``secondary`` argument to
-:func:`.relationship` is as usual passed a
-:class:`.Table` object, which is typically declared in the
-traditional way.  The :class:`.Table` usually shares
-the :class:`.MetaData` object used by the declarative base::
-
-    keywords = Table(
-        'keywords', Base.metadata,
-        Column('author_id', Integer, ForeignKey('authors.id')),
-        Column('keyword_id', Integer, ForeignKey('keywords.id'))
-        )
-
-    class Author(Base):
-        __tablename__ = 'authors'
-        id = Column(Integer, primary_key=True)
-        keywords = relationship("Keyword", secondary=keywords)
-
-Like other :func:`~sqlalchemy.orm.relationship` arguments, a string is accepted
-as well, passing the string name of the table as defined in the
-``Base.metadata.tables`` collection::
-
-    class Author(Base):
-        __tablename__ = 'authors'
-        id = Column(Integer, primary_key=True)
-        keywords = relationship("Keyword", secondary="keywords")
-
-As with traditional mapping, its generally not a good idea to use
-a :class:`.Table` as the "secondary" argument which is also mapped to
-a class, unless the :func:`.relationship` is declared with ``viewonly=True``.
-Otherwise, the unit-of-work system may attempt duplicate INSERT and
-DELETE statements against the underlying table.
-
-.. _declarative_sql_expressions:
-
-Defining SQL Expressions
-========================
-
-See :ref:`mapper_sql_expressions` for examples on declaratively
-mapping attributes to SQL expressions.
-
-.. _declarative_table_args:
-
-Table Configuration
-===================
-
-Table arguments other than the name, metadata, and mapped Column
-arguments are specified using the ``__table_args__`` class attribute.
-This attribute accommodates both positional as well as keyword
-arguments that are normally sent to the
-:class:`~sqlalchemy.schema.Table` constructor.
-The attribute can be specified in one of two forms. One is as a
-dictionary::
-
-    class MyClass(Base):
-        __tablename__ = 'sometable'
-        __table_args__ = {'mysql_engine':'InnoDB'}
-
-The other, a tuple, where each argument is positional
-(usually constraints)::
-
-    class MyClass(Base):
-        __tablename__ = 'sometable'
-        __table_args__ = (
-                ForeignKeyConstraint(['id'], ['remote_table.id']),
-                UniqueConstraint('foo'),
-                )
-
-Keyword arguments can be specified with the above form by
-specifying the last argument as a dictionary::
-
-    class MyClass(Base):
-        __tablename__ = 'sometable'
-        __table_args__ = (
-                ForeignKeyConstraint(['id'], ['remote_table.id']),
-                UniqueConstraint('foo'),
-                {'autoload':True}
-                )
-
-Using a Hybrid Approach with __table__
-=======================================
-
-As an alternative to ``__tablename__``, a direct
-:class:`~sqlalchemy.schema.Table` construct may be used.  The
-:class:`~sqlalchemy.schema.Column` objects, which in this case require
-their names, will be added to the mapping just like a regular mapping
-to a table::
-
-    class MyClass(Base):
-        __table__ = Table('my_table', Base.metadata,
-            Column('id', Integer, primary_key=True),
-            Column('name', String(50))
-        )
-
-``__table__`` provides a more focused point of control for establishing
-table metadata, while still getting most of the benefits of using declarative.
-An application that uses reflection might want to load table metadata elsewhere
-and pass it to declarative classes::
-
-    from sqlalchemy.ext.declarative import declarative_base
-
-    Base = declarative_base()
-    Base.metadata.reflect(some_engine)
-
-    class User(Base):
-        __table__ = metadata.tables['user']
-
-    class Address(Base):
-        __table__ = metadata.tables['address']
-
-Some configuration schemes may find it more appropriate to use ``__table__``,
-such as those which already take advantage of the data-driven nature of
-:class:`.Table` to customize and/or automate schema definition.
-
-Note that when the ``__table__`` approach is used, the object is immediately
-usable as a plain :class:`.Table` within the class declaration body itself,
-as a Python class is only another syntactical block.  Below this is illustrated
-by using the ``id`` column in the ``primaryjoin`` condition of a
-:func:`.relationship`::
-
-    class MyClass(Base):
-        __table__ = Table('my_table', Base.metadata,
-            Column('id', Integer, primary_key=True),
-            Column('name', String(50))
-        )
-
-        widgets = relationship(Widget,
-                    primaryjoin=Widget.myclass_id==__table__.c.id)
-
-Similarly, mapped attributes which refer to ``__table__`` can be placed inline,
-as below where we assign the ``name`` column to the attribute ``_name``,
-generating a synonym for ``name``::
-
-    from sqlalchemy.ext.declarative import synonym_for
-
-    class MyClass(Base):
-        __table__ = Table('my_table', Base.metadata,
-            Column('id', Integer, primary_key=True),
-            Column('name', String(50))
-        )
-
-        _name = __table__.c.name
-
-        @synonym_for("_name")
-        def name(self):
-            return "Name: %s" % _name
-
-Using Reflection with Declarative
-=================================
-
-It's easy to set up a :class:`.Table` that uses ``autoload=True``
-in conjunction with a mapped class::
-
-    class MyClass(Base):
-        __table__ = Table('mytable', Base.metadata,
-                        autoload=True, autoload_with=some_engine)
-
-However, one improvement that can be made here is to not
-require the :class:`.Engine` to be available when classes are
-being first declared.   To achieve this, use the
-:class:`.DeferredReflection` mixin, which sets up mappings
-only after a special ``prepare(engine)`` step is called::
-
-    from sqlalchemy.ext.declarative import declarative_base, DeferredReflection
-
-    Base = declarative_base(cls=DeferredReflection)
-
-    class Foo(Base):
-        __tablename__ = 'foo'
-        bars = relationship("Bar")
-
-    class Bar(Base):
-        __tablename__ = 'bar'
-
-        # illustrate overriding of "bar.foo_id" to have
-        # a foreign key constraint otherwise not
-        # reflected, such as when using MySQL
-        foo_id = Column(Integer, ForeignKey('foo.id'))
-
-    Base.prepare(e)
-
-.. versionadded:: 0.8
-   Added :class:`.DeferredReflection`.
-
-Mapper Configuration
-====================
-
-Declarative makes use of the :func:`~.orm.mapper` function internally
-when it creates the mapping to the declared table.   The options
-for :func:`~.orm.mapper` are passed directly through via the
-``__mapper_args__`` class attribute.  As always, arguments which reference
-locally mapped columns can reference them directly from within the
-class declaration::
-
-    from datetime import datetime
-
-    class Widget(Base):
-        __tablename__ = 'widgets'
-
-        id = Column(Integer, primary_key=True)
-        timestamp = Column(DateTime, nullable=False)
-
-        __mapper_args__ = {
-                        'version_id_col': timestamp,
-                        'version_id_generator': lambda v:datetime.now()
-                    }
-
-.. _declarative_inheritance:
-
-Inheritance Configuration
-=========================
-
-Declarative supports all three forms of inheritance as intuitively
-as possible.  The ``inherits`` mapper keyword argument is not needed
-as declarative will determine this from the class itself.   The various
-"polymorphic" keyword arguments are specified using ``__mapper_args__``.
-
-Joined Table Inheritance
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-Joined table inheritance is defined as a subclass that defines its own
-table::
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        __tablename__ = 'engineers'
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-        id = Column(Integer, ForeignKey('people.id'), primary_key=True)
-        primary_language = Column(String(50))
-
-Note that above, the ``Engineer.id`` attribute, since it shares the
-same attribute name as the ``Person.id`` attribute, will in fact
-represent the ``people.id`` and ``engineers.id`` columns together,
-with the "Engineer.id" column taking precedence if queried directly.
-To provide the ``Engineer`` class with an attribute that represents
-only the ``engineers.id`` column, give it a different attribute name::
-
-    class Engineer(Person):
-        __tablename__ = 'engineers'
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-        engineer_id = Column('id', Integer, ForeignKey('people.id'),
-                                                    primary_key=True)
-        primary_language = Column(String(50))
-
-
-.. versionchanged:: 0.7 joined table inheritance favors the subclass
-   column over that of the superclass, such as querying above
-   for ``Engineer.id``.  Prior to 0.7 this was the reverse.
-
-.. _declarative_single_table:
-
-Single Table Inheritance
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-Single table inheritance is defined as a subclass that does not have
-its own table; you just leave out the ``__table__`` and ``__tablename__``
-attributes::
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-        primary_language = Column(String(50))
-
-When the above mappers are configured, the ``Person`` class is mapped
-to the ``people`` table *before* the ``primary_language`` column is
-defined, and this column will not be included in its own mapping.
-When ``Engineer`` then defines the ``primary_language`` column, the
-column is added to the ``people`` table so that it is included in the
-mapping for ``Engineer`` and is also part of the table's full set of
-columns.  Columns which are not mapped to ``Person`` are also excluded
-from any other single or joined inheriting classes using the
-``exclude_properties`` mapper argument.  Below, ``Manager`` will have
-all the attributes of ``Person`` and ``Manager`` but *not* the
-``primary_language`` attribute of ``Engineer``::
-
-    class Manager(Person):
-        __mapper_args__ = {'polymorphic_identity': 'manager'}
-        golf_swing = Column(String(50))
-
-The attribute exclusion logic is provided by the
-``exclude_properties`` mapper argument, and declarative's default
-behavior can be disabled by passing an explicit ``exclude_properties``
-collection (empty or otherwise) to the ``__mapper_args__``.
-
-Resolving Column Conflicts
-^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Note above that the ``primary_language`` and ``golf_swing`` columns
-are "moved up" to be applied to ``Person.__table__``, as a result of their
-declaration on a subclass that has no table of its own.   A tricky case
-comes up when two subclasses want to specify *the same* column, as below::
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-        start_date = Column(DateTime)
-
-    class Manager(Person):
-        __mapper_args__ = {'polymorphic_identity': 'manager'}
-        start_date = Column(DateTime)
-
-Above, the ``start_date`` column declared on both ``Engineer`` and ``Manager``
-will result in an error::
-
-    sqlalchemy.exc.ArgumentError: Column 'start_date' on class
-    <class '__main__.Manager'> conflicts with existing
-    column 'people.start_date'
-
-In a situation like this, Declarative can't be sure
-of the intent, especially if the ``start_date`` columns had, for example,
-different types.   A situation like this can be resolved by using
-:class:`.declared_attr` to define the :class:`.Column` conditionally, taking
-care to return the **existing column** via the parent ``__table__`` if it
-already exists::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-
-        @declared_attr
-        def start_date(cls):
-            "Start date column, if not present already."
-            return Person.__table__.c.get('start_date', Column(DateTime))
-
-    class Manager(Person):
-        __mapper_args__ = {'polymorphic_identity': 'manager'}
-
-        @declared_attr
-        def start_date(cls):
-            "Start date column, if not present already."
-            return Person.__table__.c.get('start_date', Column(DateTime))
-
-Above, when ``Manager`` is mapped, the ``start_date`` column is
-already present on the ``Person`` class.  Declarative lets us return
-that :class:`.Column` as a result in this case, where it knows to skip
-re-assigning the same column. If the mapping is mis-configured such
-that the ``start_date`` column is accidentally re-assigned to a
-different table (such as, if we changed ``Manager`` to be joined
-inheritance without fixing ``start_date``), an error is raised which
-indicates an existing :class:`.Column` is trying to be re-assigned to
-a different owning :class:`.Table`.
-
-.. versionadded:: 0.8 :class:`.declared_attr` can be used on a non-mixin
-   class, and the returned :class:`.Column` or other mapped attribute
-   will be applied to the mapping as any other attribute.  Previously,
-   the resulting attribute would be ignored, and also result in a warning
-   being emitted when a subclass was created.
-
-.. versionadded:: 0.8 :class:`.declared_attr`, when used either with a
-   mixin or non-mixin declarative class, can return an existing
-   :class:`.Column` already assigned to the parent :class:`.Table`,
-   to indicate that the re-assignment of the :class:`.Column` should be
-   skipped, however should still be mapped on the target class,
-   in order to resolve duplicate column conflicts.
-
-The same concept can be used with mixin classes (see
-:ref:`declarative_mixins`)::
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class HasStartDate(object):
-        @declared_attr
-        def start_date(cls):
-            return cls.__table__.c.get('start_date', Column(DateTime))
-
-    class Engineer(HasStartDate, Person):
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-
-    class Manager(HasStartDate, Person):
-        __mapper_args__ = {'polymorphic_identity': 'manager'}
-
-The above mixin checks the local ``__table__`` attribute for the column.
-Because we're using single table inheritance, we're sure that in this case,
-``cls.__table__`` refers to ``People.__table__``.  If we were mixing joined-
-and single-table inheritance, we might want our mixin to check more carefully
-if ``cls.__table__`` is really the :class:`.Table` we're looking for.
-
-Concrete Table Inheritance
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Concrete is defined as a subclass which has its own table and sets the
-``concrete`` keyword argument to ``True``::
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        name = Column(String(50))
-
-    class Engineer(Person):
-        __tablename__ = 'engineers'
-        __mapper_args__ = {'concrete':True}
-        id = Column(Integer, primary_key=True)
-        primary_language = Column(String(50))
-        name = Column(String(50))
-
-Usage of an abstract base class is a little less straightforward as it
-requires usage of :func:`~sqlalchemy.orm.util.polymorphic_union`,
-which needs to be created with the :class:`.Table` objects
-before the class is built::
-
-    engineers = Table('engineers', Base.metadata,
-                    Column('id', Integer, primary_key=True),
-                    Column('name', String(50)),
-                    Column('primary_language', String(50))
-                )
-    managers = Table('managers', Base.metadata,
-                    Column('id', Integer, primary_key=True),
-                    Column('name', String(50)),
-                    Column('golf_swing', String(50))
-                )
-
-    punion = polymorphic_union({
-        'engineer':engineers,
-        'manager':managers
-    }, 'type', 'punion')
-
-    class Person(Base):
-        __table__ = punion
-        __mapper_args__ = {'polymorphic_on':punion.c.type}
-
-    class Engineer(Person):
-        __table__ = engineers
-        __mapper_args__ = {'polymorphic_identity':'engineer', 'concrete':True}
-
-    class Manager(Person):
-        __table__ = managers
-        __mapper_args__ = {'polymorphic_identity':'manager', 'concrete':True}
-
-.. _declarative_concrete_helpers:
-
-Using the Concrete Helpers
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Helper classes provides a simpler pattern for concrete inheritance.
-With these objects, the ``__declare_first__`` helper is used to configure the
-"polymorphic" loader for the mapper after all subclasses have been declared.
-
-.. versionadded:: 0.7.3
-
-An abstract base can be declared using the
-:class:`.AbstractConcreteBase` class::
-
-    from sqlalchemy.ext.declarative import AbstractConcreteBase
-
-    class Employee(AbstractConcreteBase, Base):
-        pass
-
-To have a concrete ``employee`` table, use :class:`.ConcreteBase` instead::
-
-    from sqlalchemy.ext.declarative import ConcreteBase
-
-    class Employee(ConcreteBase, Base):
-        __tablename__ = 'employee'
-        employee_id = Column(Integer, primary_key=True)
-        name = Column(String(50))
-        __mapper_args__ = {
-                        'polymorphic_identity':'employee',
-                        'concrete':True}
-
-
-Either ``Employee`` base can be used in the normal fashion::
-
-    class Manager(Employee):
-        __tablename__ = 'manager'
-        employee_id = Column(Integer, primary_key=True)
-        name = Column(String(50))
-        manager_data = Column(String(40))
-        __mapper_args__ = {
-                        'polymorphic_identity':'manager',
-                        'concrete':True}
-
-    class Engineer(Employee):
-        __tablename__ = 'engineer'
-        employee_id = Column(Integer, primary_key=True)
-        name = Column(String(50))
-        engineer_info = Column(String(40))
-        __mapper_args__ = {'polymorphic_identity':'engineer',
-                        'concrete':True}
-
-
-The :class:`.AbstractConcreteBase` class is itself mapped, and can be
-used as a target of relationships::
-
-    class Company(Base):
-        __tablename__ = 'company'
-
-        id = Column(Integer, primary_key=True)
-        employees = relationship("Employee",
-                        primaryjoin="Company.id == Employee.company_id")
-
-
-.. versionchanged:: 0.9.3 Support for use of :class:`.AbstractConcreteBase`
-   as the target of a :func:`.relationship` has been improved.
-
-It can also be queried directly::
-
-    for employee in session.query(Employee).filter(Employee.name == 'qbert'):
-        print(employee)
-
-
-.. _declarative_mixins:
-
-Mixin and Custom Base Classes
-==============================
-
-A common need when using :mod:`~sqlalchemy.ext.declarative` is to
-share some functionality, such as a set of common columns, some common
-table options, or other mapped properties, across many
-classes.  The standard Python idioms for this is to have the classes
-inherit from a base which includes these common features.
-
-When using :mod:`~sqlalchemy.ext.declarative`, this idiom is allowed
-via the usage of a custom declarative base class, as well as a "mixin" class
-which is inherited from in addition to the primary base.  Declarative
-includes several helper features to make this work in terms of how
-mappings are declared.   An example of some commonly mixed-in
-idioms is below::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class MyMixin(object):
-
-        @declared_attr
-        def __tablename__(cls):
-            return cls.__name__.lower()
-
-        __table_args__ = {'mysql_engine': 'InnoDB'}
-        __mapper_args__= {'always_refresh': True}
-
-        id =  Column(Integer, primary_key=True)
-
-    class MyModel(MyMixin, Base):
-        name = Column(String(1000))
-
-Where above, the class ``MyModel`` will contain an "id" column
-as the primary key, a ``__tablename__`` attribute that derives
-from the name of the class itself, as well as ``__table_args__``
-and ``__mapper_args__`` defined by the ``MyMixin`` mixin class.
-
-There's no fixed convention over whether ``MyMixin`` precedes
-``Base`` or not.  Normal Python method resolution rules apply, and
-the above example would work just as well with::
-
-    class MyModel(Base, MyMixin):
-        name = Column(String(1000))
-
-This works because ``Base`` here doesn't define any of the
-variables that ``MyMixin`` defines, i.e. ``__tablename__``,
-``__table_args__``, ``id``, etc.   If the ``Base`` did define
-an attribute of the same name, the class placed first in the
-inherits list would determine which attribute is used on the
-newly defined class.
-
-Augmenting the Base
-~~~~~~~~~~~~~~~~~~~
-
-In addition to using a pure mixin, most of the techniques in this
-section can also be applied to the base class itself, for patterns that
-should apply to all classes derived from a particular base.  This is achieved
-using the ``cls`` argument of the :func:`.declarative_base` function::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class Base(object):
-        @declared_attr
-        def __tablename__(cls):
-            return cls.__name__.lower()
-
-        __table_args__ = {'mysql_engine': 'InnoDB'}
-
-        id =  Column(Integer, primary_key=True)
-
-    from sqlalchemy.ext.declarative import declarative_base
-
-    Base = declarative_base(cls=Base)
-
-    class MyModel(Base):
-        name = Column(String(1000))
-
-Where above, ``MyModel`` and all other classes that derive from ``Base`` will
-have a table name derived from the class name, an ``id`` primary key column,
-as well as the "InnoDB" engine for MySQL.
-
-Mixing in Columns
-~~~~~~~~~~~~~~~~~
-
-The most basic way to specify a column on a mixin is by simple
-declaration::
-
-    class TimestampMixin(object):
-        created_at = Column(DateTime, default=func.now())
-
-    class MyModel(TimestampMixin, Base):
-        __tablename__ = 'test'
-
-        id =  Column(Integer, primary_key=True)
-        name = Column(String(1000))
-
-Where above, all declarative classes that include ``TimestampMixin``
-will also have a column ``created_at`` that applies a timestamp to
-all row insertions.
-
-Those familiar with the SQLAlchemy expression language know that
-the object identity of clause elements defines their role in a schema.
-Two ``Table`` objects ``a`` and ``b`` may both have a column called
-``id``, but the way these are differentiated is that ``a.c.id``
-and ``b.c.id`` are two distinct Python objects, referencing their
-parent tables ``a`` and ``b`` respectively.
-
-In the case of the mixin column, it seems that only one
-:class:`.Column` object is explicitly created, yet the ultimate
-``created_at`` column above must exist as a distinct Python object
-for each separate destination class.  To accomplish this, the declarative
-extension creates a **copy** of each :class:`.Column` object encountered on
-a class that is detected as a mixin.
-
-This copy mechanism is limited to simple columns that have no foreign
-keys, as a :class:`.ForeignKey` itself contains references to columns
-which can't be properly recreated at this level.  For columns that
-have foreign keys, as well as for the variety of mapper-level constructs
-that require destination-explicit context, the
-:class:`~.declared_attr` decorator is provided so that
-patterns common to many classes can be defined as callables::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class ReferenceAddressMixin(object):
-        @declared_attr
-        def address_id(cls):
-            return Column(Integer, ForeignKey('address.id'))
-
-    class User(ReferenceAddressMixin, Base):
-        __tablename__ = 'user'
-        id = Column(Integer, primary_key=True)
-
-Where above, the ``address_id`` class-level callable is executed at the
-point at which the ``User`` class is constructed, and the declarative
-extension can use the resulting :class:`.Column` object as returned by
-the method without the need to copy it.
-
-.. versionchanged:: > 0.6.5
-    Rename 0.6.5 ``sqlalchemy.util.classproperty``
-    into :class:`~.declared_attr`.
-
-Columns generated by :class:`~.declared_attr` can also be
-referenced by ``__mapper_args__`` to a limited degree, currently
-by ``polymorphic_on`` and ``version_id_col``, by specifying the
-classdecorator itself into the dictionary - the declarative extension
-will resolve them at class construction time::
-
-    class MyMixin:
-        @declared_attr
-        def type_(cls):
-            return Column(String(50))
-
-        __mapper_args__= {'polymorphic_on':type_}
-
-    class MyModel(MyMixin, Base):
-        __tablename__='test'
-        id =  Column(Integer, primary_key=True)
-
-
-
-Mixing in Relationships
-~~~~~~~~~~~~~~~~~~~~~~~
-
-Relationships created by :func:`~sqlalchemy.orm.relationship` are provided
-with declarative mixin classes exclusively using the
-:class:`.declared_attr` approach, eliminating any ambiguity
-which could arise when copying a relationship and its possibly column-bound
-contents. Below is an example which combines a foreign key column and a
-relationship so that two classes ``Foo`` and ``Bar`` can both be configured to
-reference a common target class via many-to-one::
-
-    class RefTargetMixin(object):
-        @declared_attr
-        def target_id(cls):
-            return Column('target_id', ForeignKey('target.id'))
-
-        @declared_attr
-        def target(cls):
-            return relationship("Target")
-
-    class Foo(RefTargetMixin, Base):
-        __tablename__ = 'foo'
-        id = Column(Integer, primary_key=True)
-
-    class Bar(RefTargetMixin, Base):
-        __tablename__ = 'bar'
-        id = Column(Integer, primary_key=True)
-
-    class Target(Base):
-        __tablename__ = 'target'
-        id = Column(Integer, primary_key=True)
-
-Using Advanced Relationship Arguments (e.g. ``primaryjoin``, etc.)
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-:func:`~sqlalchemy.orm.relationship` definitions which require explicit
-primaryjoin, order_by etc. expressions should in all but the most
-simplistic cases use **late bound** forms
-for these arguments, meaning, using either the string form or a lambda.
-The reason for this is that the related :class:`.Column` objects which are to
-be configured using ``@declared_attr`` are not available to another
-``@declared_attr`` attribute; while the methods will work and return new
-:class:`.Column` objects, those are not the :class:`.Column` objects that
-Declarative will be using as it calls the methods on its own, thus using
-*different* :class:`.Column` objects.
-
-The canonical example is the primaryjoin condition that depends upon
-another mixed-in column::
-
-    class RefTargetMixin(object):
-        @declared_attr
-        def target_id(cls):
-            return Column('target_id', ForeignKey('target.id'))
-
-        @declared_attr
-        def target(cls):
-            return relationship(Target,
-                primaryjoin=Target.id==cls.target_id   # this is *incorrect*
-            )
-
-Mapping a class using the above mixin, we will get an error like::
-
-    sqlalchemy.exc.InvalidRequestError: this ForeignKey's parent column is not
-    yet associated with a Table.
-
-This is because the ``target_id`` :class:`.Column` we've called upon in our ``target()``
-method is not the same :class:`.Column` that declarative is actually going to map
-to our table.
-
-The condition above is resolved using a lambda::
-
-    class RefTargetMixin(object):
-        @declared_attr
-        def target_id(cls):
-            return Column('target_id', ForeignKey('target.id'))
-
-        @declared_attr
-        def target(cls):
-            return relationship(Target,
-                primaryjoin=lambda: Target.id==cls.target_id
-            )
-
-or alternatively, the string form (which ultmately generates a lambda)::
-
-    class RefTargetMixin(object):
-        @declared_attr
-        def target_id(cls):
-            return Column('target_id', ForeignKey('target.id'))
-
-        @declared_attr
-        def target(cls):
-            return relationship("Target",
-                primaryjoin="Target.id==%s.target_id" % cls.__name__
-            )
-
-Mixing in deferred(), column_property(), and other MapperProperty classes
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Like :func:`~sqlalchemy.orm.relationship`, all
-:class:`~sqlalchemy.orm.interfaces.MapperProperty` subclasses such as
-:func:`~sqlalchemy.orm.deferred`, :func:`~sqlalchemy.orm.column_property`,
-etc. ultimately involve references to columns, and therefore, when
-used with declarative mixins, have the :class:`.declared_attr`
-requirement so that no reliance on copying is needed::
-
-    class SomethingMixin(object):
-
-        @declared_attr
-        def dprop(cls):
-            return deferred(Column(Integer))
-
-    class Something(SomethingMixin, Base):
-        __tablename__ = "something"
-
-Mixing in Association Proxy and Other Attributes
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Mixins can specify user-defined attributes as well as other extension
-units such as :func:`.association_proxy`.   The usage of
-:class:`.declared_attr` is required in those cases where the attribute must
-be tailored specifically to the target subclass.   An example is when
-constructing multiple :func:`.association_proxy` attributes which each
-target a different type of child object.  Below is an
-:func:`.association_proxy` / mixin example which provides a scalar list of
-string values to an implementing class::
-
-    from sqlalchemy import Column, Integer, ForeignKey, String
-    from sqlalchemy.orm import relationship
-    from sqlalchemy.ext.associationproxy import association_proxy
-    from sqlalchemy.ext.declarative import declarative_base, declared_attr
-
-    Base = declarative_base()

-
-Above, the ``HasStringCollection`` mixin produces a :func:`.relationship`
-which refers to a newly generated class called ``StringAttribute``.  The
-``StringAttribute`` class is generated with it's own :class:`.Table`
-definition which is local to the parent class making usage of the
-``HasStringCollection`` mixin.  It also produces an :func:`.association_proxy`
-object which proxies references to the ``strings`` attribute onto the ``value``
-attribute of each ``StringAttribute`` instance.
-
-``TypeA`` or ``TypeB`` can be instantiated given the constructor
-argument ``strings``, a list of strings::
-
-    ta = TypeA(strings=['foo', 'bar'])
-    tb = TypeA(strings=['bat', 'bar'])
-
-This list will generate a collection
-of ``StringAttribute`` objects, which are persisted into a table that's
-local to either the ``type_a_strings`` or ``type_b_strings`` table::
-
-    >>> print ta._strings
-    [<__main__.StringAttribute object at 0x10151cd90>,
-        <__main__.StringAttribute object at 0x10151ce10>]
-
-When constructing the :func:`.association_proxy`, the
-:class:`.declared_attr` decorator must be used so that a distinct
-:func:`.association_proxy` object is created for each of the ``TypeA``
-and ``TypeB`` classes.
-
-.. versionadded:: 0.8 :class:`.declared_attr` is usable with non-mapped
-   attributes, including user-defined attributes as well as
-   :func:`.association_proxy`.
-
-
-Controlling table inheritance with mixins
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The ``__tablename__`` attribute in conjunction with the hierarchy of
-classes involved in a declarative mixin scenario controls what type of
-table inheritance, if any,
-is configured by the declarative extension.
-
-If the ``__tablename__`` is computed by a mixin, you may need to
-control which classes get the computed attribute in order to get the
-type of table inheritance you require.
-
-For example, if you had a mixin that computes ``__tablename__`` but
-where you wanted to use that mixin in a single table inheritance
-hierarchy, you can explicitly specify ``__tablename__`` as ``None`` to
-indicate that the class should not have a table mapped::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class Tablename:
-        @declared_attr
-        def __tablename__(cls):
-            return cls.__name__.lower()
-
-    class Person(Tablename, Base):
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        __tablename__ = None
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-        primary_language = Column(String(50))
-
-Alternatively, you can make the mixin intelligent enough to only
-return a ``__tablename__`` in the event that no table is already
-mapped in the inheritance hierarchy. To help with this, a
-:func:`~sqlalchemy.ext.declarative.has_inherited_table` helper
-function is provided that returns ``True`` if a parent class already
-has a mapped table.
-
-As an example, here's a mixin that will only allow single table
-inheritance::
-
-    from sqlalchemy.ext.declarative import declared_attr
-    from sqlalchemy.ext.declarative import has_inherited_table
-
-    class Tablename(object):
-        @declared_attr
-        def __tablename__(cls):
-            if has_inherited_table(cls):
-                return None
-            return cls.__name__.lower()
-
-    class Person(Tablename, Base):
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        primary_language = Column(String(50))
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-
-
-Combining Table/Mapper Arguments from Multiple Mixins
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-In the case of ``__table_args__`` or ``__mapper_args__``
-specified with declarative mixins, you may want to combine
-some parameters from several mixins with those you wish to
-define on the class iteself. The
-:class:`.declared_attr` decorator can be used
-here to create user-defined collation routines that pull
-from multiple collections::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class MySQLSettings(object):
-        __table_args__ = {'mysql_engine':'InnoDB'}
-
-    class MyOtherMixin(object):
-        __table_args__ = {'info':'foo'}
-
-    class MyModel(MySQLSettings, MyOtherMixin, Base):
-        __tablename__='my_model'
-
-        @declared_attr
-        def __table_args__(cls):
-            args = dict()
-            args.update(MySQLSettings.__table_args__)
-            args.update(MyOtherMixin.__table_args__)
-            return args
-
-        id =  Column(Integer, primary_key=True)
-
-Creating Indexes with Mixins
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-To define a named, potentially multicolumn :class:`.Index` that applies to all
-tables derived from a mixin, use the "inline" form of :class:`.Index` and
-establish it as part of ``__table_args__``::
-
-    class MyMixin(object):
-        a =  Column(Integer)
-        b =  Column(Integer)
-
-        @declared_attr
-        def __table_args__(cls):
-            return (Index('test_idx_%s' % cls.__tablename__, 'a', 'b'),)
-
-    class MyModel(MyMixin, Base):
-        __tablename__ = 'atable'
-        c =  Column(Integer,primary_key=True)
-
-Special Directives
-==================
-
-``__declare_last__()``
-~~~~~~~~~~~~~~~~~~~~~~
-
-The ``__declare_last__()`` hook allows definition of
-a class level function that is automatically called by the
-:meth:`.MapperEvents.after_configured` event, which occurs after mappings are
-assumed to be completed and the 'configure' step has finished::
-
-    class MyClass(Base):
-        @classmethod
-        def __declare_last__(cls):
-            ""
-            # do something with mappings
-
-.. versionadded:: 0.7.3
-
-``__declare_first__()``
-~~~~~~~~~~~~~~~~~~~~~~~
-
-Like ``__declare_last__()``, but is called at the beginning of mapper configuration
-via the :meth:`.MapperEvents.before_configured` event::
-
-    class MyClass(Base):
-        @classmethod
-        def __declare_first__(cls):
-            ""
-            # do something before mappings are configured
-
-.. versionadded:: 0.9.3
-
-.. _declarative_abstract:
-
-``__abstract__``
-~~~~~~~~~~~~~~~~~~~
-
-``__abstract__`` causes declarative to skip the production
-of a table or mapper for the class entirely.  A class can be added within a
-hierarchy in the same way as mixin (see :ref:`declarative_mixins`), allowing
-subclasses to extend just from the special class::
-
-    class SomeAbstractBase(Base):
-        __abstract__ = True
-
-        def some_helpful_method(self):
-            ""
-
-        @declared_attr
-        def __mapper_args__(cls):
-            return {"helpful mapper arguments":True}
-
-    class MyMappedClass(SomeAbstractBase):
-        ""
-
-One possible use of ``__abstract__`` is to use a distinct
-:class:`.MetaData` for different bases::
-
-    Base = declarative_base()
-
-    class DefaultBase(Base):
-        __abstract__ = True
-        metadata = MetaData()
-
-    class OtherBase(Base):
-        __abstract__ = True
-        metadata = MetaData()
-
-Above, classes which inherit from ``DefaultBase`` will use one
-:class:`.MetaData` as the registry of tables, and those which inherit from
-``OtherBase`` will use a different one. The tables themselves can then be
-created perhaps within distinct databases::
-
-    DefaultBase.metadata.create_all(some_engine)
-    OtherBase.metadata_create_all(some_other_engine)
-
-.. versionadded:: 0.7.3
-
-Class Constructor
-=================
-
-As a convenience feature, the :func:`declarative_base` sets a default
-constructor on classes which takes keyword arguments, and assigns them
-to the named attributes::
-
-    e = Engineer(primary_language='python')
-
-Sessions
-========
-
-Note that ``declarative`` does nothing special with sessions, and is
-only intended as an easier way to configure mappers and
-:class:`~sqlalchemy.schema.Table` objects.  A typical application
-setup using :class:`~sqlalchemy.orm.scoping.scoped_session` might look like::
-
-    engine = create_engine('postgresql://scott:tiger@localhost/test')
-    Session = scoped_session(sessionmaker(autocommit=False,
-                                          autoflush=False,
-                                          bind=engine))
-    Base = declarative_base()
-
-Mapped instances then make usage of
-:class:`~sqlalchemy.orm.session.Session` in the usual way.

-class DeferredReflection(object):
-    """A helper class for construction of mappings based on
-    a deferred reflection step.
-
-    Normally, declarative can be used with reflection by
-    setting a :class:`.Table` object using autoload=True
-    as the ``__table__`` attribute on a declarative class.
-    The caveat is that the :class:`.Table` must be fully
-    reflected, or at the very least have a primary key column,
-    at the point at which a normal declarative mapping is
-    constructed, meaning the :class:`.Engine` must be available
-    at class declaration time.
-
-    The :class:`.DeferredReflection` mixin moves the construction
-    of mappers to be at a later point, after a specific
-    method is called which first reflects all :class:`.Table`
-    objects created so far.   Classes can define it as such::
-
-        from sqlalchemy.ext.declarative import declarative_base
-        from sqlalchemy.ext.declarative import DeferredReflection
-        Base = declarative_base()
-
-        class MyClass(DeferredReflection, Base):
-            __tablename__ = 'mytable'
-
-    Above, ``MyClass`` is not yet mapped.   After a series of
-    classes have been defined in the above fashion, all tables
-    can be reflected and mappings created using
-    :meth:`.prepare`::
-
-        engine = create_engine("someengine://...")
-        DeferredReflection.prepare(engine)
-
-    The :class:`.DeferredReflection` mixin can be applied to individual
-    classes, used as the base for the declarative base itself,
-    or used in a custom abstract class.   Using an abstract base
-    allows that only a subset of classes to be prepared for a
-    particular prepare step, which is necessary for applications
-    that use more than one engine.  For example, if an application
-    has two engines, you might use two bases, and prepare each
-    separately, e.g.::
-
-        class ReflectedOne(DeferredReflection, Base):
-            __abstract__ = True
-
-        class ReflectedTwo(DeferredReflection, Base):
-            __abstract__ = True
-
-        class MyClass(ReflectedOne):
-            __tablename__ = 'mytable'
-
-        class MyOtherClass(ReflectedOne):
-            __tablename__ = 'myothertable'
-
-        class YetAnotherClass(ReflectedTwo):
-            __tablename__ = 'yetanothertable'
-
-        # ... etc.
-
-    Above, the class hierarchies for ``ReflectedOne`` and
-    ``ReflectedTwo`` can be configured separately::
-
-        ReflectedOne.prepare(engine_one)
-        ReflectedTwo.prepare(engine_two)

-"""Define attributes on ORM-mapped classes that have "hybrid" behavior.
-
-"hybrid" means the attribute has distinct behaviors defined at the
-class level and at the instance level.
-
-The :mod:`~sqlalchemy.ext.hybrid` extension provides a special form of
-method decorator, is around 50 lines of code and has almost no
-dependencies on the rest of SQLAlchemy.  It can, in theory, work with
-any descriptor-based expression system.
-
-Consider a mapping ``Interval``, representing integer ``start`` and ``end``
-values. We can define higher level functions on mapped classes that produce
-SQL expressions at the class level, and Python expression evaluation at the
-instance level.  Below, each function decorated with :class:`.hybrid_method` or
-:class:`.hybrid_property` may receive ``self`` as an instance of the class, or
-as the class itself::
-
-    from sqlalchemy import Column, Integer
-    from sqlalchemy.ext.declarative import declarative_base
-    from sqlalchemy.orm import Session, aliased
-    from sqlalchemy.ext.hybrid import hybrid_property, hybrid_method
-
-    Base = declarative_base()
-
-    class Interval(Base):
-        __tablename__ = 'interval'
-
-        id = Column(Integer, primary_key=True)
-        start = Column(Integer, nullable=False)
-        end = Column(Integer, nullable=False)
-
-        def __init__(self, start, end):
-            self.start = start
-            self.end = end
-
-        @hybrid_property
-        def length(self):
-            return self.end - self.start
-
-        @hybrid_method
-        def contains(self,point):
-            return (self.start <= point) & (point < self.end)
-
-        @hybrid_method
-        def intersects(self, other):
-            return self.contains(other.start) | self.contains(other.end)
-
-Above, the ``length`` property returns the difference between the
-``end`` and ``start`` attributes.  With an instance of ``Interval``,
-this subtraction occurs in Python, using normal Python descriptor
-mechanics::
-
-    >>> i1 = Interval(5, 10)
-    >>> i1.length
-    5
-
-When dealing with the ``Interval`` class itself, the :class:`.hybrid_property`
-descriptor evaluates the function body given the ``Interval`` class as
-the argument, which when evaluated with SQLAlchemy expression mechanics
-returns a new SQL expression::
-
-    >>> print Interval.length
-    interval."end" - interval.start
-
-    >>> print Session().query(Interval).filter(Interval.length > 10)
-    SELECT interval.id AS interval_id, interval.start AS interval_start,
-    interval."end" AS interval_end
-    FROM interval
-    WHERE interval."end" - interval.start > :param_1
-
-ORM methods such as :meth:`~.Query.filter_by` generally use ``getattr()`` to
-locate attributes, so can also be used with hybrid attributes::
-
-    >>> print Session().query(Interval).filter_by(length=5)
-    SELECT interval.id AS interval_id, interval.start AS interval_start,
-    interval."end" AS interval_end
-    FROM interval
-    WHERE interval."end" - interval.start = :param_1
-
-The ``Interval`` class example also illustrates two methods,
-``contains()`` and ``intersects()``, decorated with
-:class:`.hybrid_method`. This decorator applies the same idea to
-methods that :class:`.hybrid_property` applies to attributes.   The
-methods return boolean values, and take advantage of the Python ``|``
-and ``&`` bitwise operators to produce equivalent instance-level and
-SQL expression-level boolean behavior::
-
-    >>> i1.contains(6)
-    True
-    >>> i1.contains(15)
-    False
-    >>> i1.intersects(Interval(7, 18))
-    True
-    >>> i1.intersects(Interval(25, 29))
-    False
-
-    >>> print Session().query(Interval).filter(Interval.contains(15))
-    SELECT interval.id AS interval_id, interval.start AS interval_start,
-    interval."end" AS interval_end
-    FROM interval
-    WHERE interval.start <= :start_1 AND interval."end" > :end_1
-
-    >>> ia = aliased(Interval)
-    >>> print Session().query(Interval, ia).filter(Interval.intersects(ia))
-    SELECT interval.id AS interval_id, interval.start AS interval_start,
-    interval."end" AS interval_end, interval_1.id AS interval_1_id,
-    interval_1.start AS interval_1_start, interval_1."end" AS interval_1_end
-    FROM interval, interval AS interval_1
-    WHERE interval.start <= interval_1.start
-        AND interval."end" > interval_1.start
-        OR interval.start <= interval_1."end"
-        AND interval."end" > interval_1."end"
-
-Defining Expression Behavior Distinct from Attribute Behavior
---------------------------------------------------------------
-
-Our usage of the ``&`` and ``|`` bitwise operators above was
-fortunate, considering our functions operated on two boolean values to
-return a new one.   In many cases, the construction of an in-Python
-function and a SQLAlchemy SQL expression have enough differences that
-two separate Python expressions should be defined.  The
-:mod:`~sqlalchemy.ext.hybrid` decorators define the
-:meth:`.hybrid_property.expression` modifier for this purpose.   As an
-example we'll define the radius of the interval, which requires the
-usage of the absolute value function::
-
-    from sqlalchemy import func
-
-    class Interval(object):
-        # ...
-
-        @hybrid_property
-        def radius(self):
-            return abs(self.length) / 2
-
-        @radius.expression
-        def radius(cls):
-            return func.abs(cls.length) / 2
-
-Above the Python function ``abs()`` is used for instance-level
-operations, the SQL function ``ABS()`` is used via the :attr:`.func`
-object for class-level expressions::
-
-    >>> i1.radius
-    2
-
-    >>> print Session().query(Interval).filter(Interval.radius > 5)
-    SELECT interval.id AS interval_id, interval.start AS interval_start,
-        interval."end" AS interval_end
-    FROM interval
-    WHERE abs(interval."end" - interval.start) / :abs_1 > :param_1
-
-Defining Setters
-----------------
-
-Hybrid properties can also define setter methods.  If we wanted
-``length`` above, when set, to modify the endpoint value::
-
-    class Interval(object):
-        # ...
-
-        @hybrid_property
-        def length(self):
-            return self.end - self.start
-
-        @length.setter
-        def length(self, value):
-            self.end = self.start + value
-
-The ``length(self, value)`` method is now called upon set::
-
-    >>> i1 = Interval(5, 10)
-    >>> i1.length
-    5
-    >>> i1.length = 12
-    >>> i1.end
-    17
-
-Working with Relationships
---------------------------
-
-There's no essential difference when creating hybrids that work with
-related objects as opposed to column-based data. The need for distinct
-expressions tends to be greater.  Two variants of we'll illustrate
-are the "join-dependent" hybrid, and the "correlated subquery" hybrid.
-
-Join-Dependent Relationship Hybrid
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Consider the following declarative
-mapping which relates a ``User`` to a ``SavingsAccount``::
-
-    from sqlalchemy import Column, Integer, ForeignKey, Numeric, String
-    from sqlalchemy.orm import relationship
-    from sqlalchemy.ext.declarative import declarative_base
-    from sqlalchemy.ext.hybrid import hybrid_property
-
-    Base = declarative_base()
-
-    class SavingsAccount(Base):
-        __tablename__ = 'account'
-        id = Column(Integer, primary_key=True)
-        user_id = Column(Integer, ForeignKey('user.id'), nullable=False)
-        balance = Column(Numeric(15, 5))
-
-    class User(Base):
-        __tablename__ = 'user'
-        id = Column(Integer, primary_key=True)
-        name = Column(String(100), nullable=False)
-
-        accounts = relationship("SavingsAccount", backref="owner")
-
-        @hybrid_property
-        def balance(self):
-            if self.accounts:
-                return self.accounts[0].balance
-            else:
-                return None
-
-        @balance.setter
-        def balance(self, value):
-            if not self.accounts:
-                account = Account(owner=self)
-            else:
-                account = self.accounts[0]
-            account.balance = value
-
-        @balance.expression
-        def balance(cls):
-            return SavingsAccount.balance
-
-The above hybrid property ``balance`` works with the first
-``SavingsAccount`` entry in the list of accounts for this user.   The
-in-Python getter/setter methods can treat ``accounts`` as a Python
-list available on ``self``.
-
-However, at the expression level, it's expected that the ``User`` class will
-be used in an appropriate context such that an appropriate join to
-``SavingsAccount`` will be present::
-
-    >>> print Session().query(User, User.balance).\\
-    ...     join(User.accounts).filter(User.balance > 5000)
-    SELECT "user".id AS user_id, "user".name AS user_name,
-    account.balance AS account_balance
-    FROM "user" JOIN account ON "user".id = account.user_id
-    WHERE account.balance > :balance_1
-
-Note however, that while the instance level accessors need to worry
-about whether ``self.accounts`` is even present, this issue expresses
-itself differently at the SQL expression level, where we basically
-would use an outer join::
-
-    >>> from sqlalchemy import or_
-    >>> print (Session().query(User, User.balance).outerjoin(User.accounts).
-    ...         filter(or_(User.balance < 5000, User.balance == None)))
-    SELECT "user".id AS user_id, "user".name AS user_name,
-    account.balance AS account_balance
-    FROM "user" LEFT OUTER JOIN account ON "user".id = account.user_id
-    WHERE account.balance <  :balance_1 OR account.balance IS NULL
-
-Correlated Subquery Relationship Hybrid
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-We can, of course, forego being dependent on the enclosing query's usage
-of joins in favor of the correlated subquery, which can portably be packed
-into a single column expression. A correlated subquery is more portable, but
-often performs more poorly at the SQL level. Using the same technique
-illustrated at :ref:`mapper_column_property_sql_expressions`,
-we can adjust our ``SavingsAccount`` example to aggregate the balances for
-*all* accounts, and use a correlated subquery for the column expression::
-
-    from sqlalchemy import Column, Integer, ForeignKey, Numeric, String
-    from sqlalchemy.orm import relationship
-    from sqlalchemy.ext.declarative import declarative_base
-    from sqlalchemy.ext.hybrid import hybrid_property
-    from sqlalchemy import select, func
-
-    Base = declarative_base()
-
-    class SavingsAccount(Base):
-        __tablename__ = 'account'
-        id = Column(Integer, primary_key=True)
-        user_id = Column(Integer, ForeignKey('user.id'), nullable=False)
-        balance = Column(Numeric(15, 5))
-
-    class User(Base):
-        __tablename__ = 'user'
-        id = Column(Integer, primary_key=True)
-        name = Column(String(100), nullable=False)
-
-        accounts = relationship("SavingsAccount", backref="owner")
-
-        @hybrid_property
-        def balance(self):
-            return sum(acc.balance for acc in self.accounts)
-
-        @balance.expression
-        def balance(cls):
-            return select([func.sum(SavingsAccount.balance)]).\\
-                    where(SavingsAccount.user_id==cls.id).\\
-                    label('total_balance')
-
-The above recipe will give us the ``balance`` column which renders
-a correlated SELECT::
-
-    >>> print s.query(User).filter(User.balance > 400)
-    SELECT "user".id AS user_id, "user".name AS user_name
-    FROM "user"
-    WHERE (SELECT sum(account.balance) AS sum_1
-    FROM account
-    WHERE account.user_id = "user".id) > :param_1
-
-.. _hybrid_custom_comparators:
-
-Building Custom Comparators
----------------------------
-
-The hybrid property also includes a helper that allows construction of
-custom comparators. A comparator object allows one to customize the
-behavior of each SQLAlchemy expression operator individually.  They
-are useful when creating custom types that have some highly
-idiosyncratic behavior on the SQL side.
-
-The example class below allows case-insensitive comparisons on the attribute
-named ``word_insensitive``::
-
-    from sqlalchemy.ext.hybrid import Comparator, hybrid_property
-    from sqlalchemy import func, Column, Integer, String
-    from sqlalchemy.orm import Session
-    from sqlalchemy.ext.declarative import declarative_base
-
-    Base = declarative_base()
-
-    class CaseInsensitiveComparator(Comparator):
-        def __eq__(self, other):
-            return func.lower(self.__clause_element__()) == func.lower(other)
-
-    class SearchWord(Base):
-        __tablename__ = 'searchword'
-        id = Column(Integer, primary_key=True)
-        word = Column(String(255), nullable=False)
-
-        @hybrid_property
-        def word_insensitive(self):
-            return self.word.lower()
-
-        @word_insensitive.comparator
-        def word_insensitive(cls):
-            return CaseInsensitiveComparator(cls.word)
-
-Above, SQL expressions against ``word_insensitive`` will apply the ``LOWER()``
-SQL function to both sides::
-
-    >>> print Session().query(SearchWord).filter_by(word_insensitive="Trucks")
-    SELECT searchword.id AS searchword_id, searchword.word AS searchword_word
-    FROM searchword
-    WHERE lower(searchword.word) = lower(:lower_1)
-
-The ``CaseInsensitiveComparator`` above implements part of the
-:class:`.ColumnOperators` interface.   A "coercion" operation like
-lowercasing can be applied to all comparison operations (i.e. ``eq``,
-``lt``, ``gt``, etc.) using :meth:`.Operators.operate`::
-
-    class CaseInsensitiveComparator(Comparator):
-        def operate(self, op, other):
-            return op(func.lower(self.__clause_element__()), func.lower(other))
-
-Hybrid Value Objects
---------------------
-
-Note in our previous example, if we were to compare the
-``word_insensitive`` attribute of a ``SearchWord`` instance to a plain
-Python string, the plain Python string would not be coerced to lower
-case - the ``CaseInsensitiveComparator`` we built, being returned by
-``@word_insensitive.comparator``, only applies to the SQL side.
-
-A more comprehensive form of the custom comparator is to construct a
-*Hybrid Value Object*. This technique applies the target value or
-expression to a value object which is then returned by the accessor in
-all cases.   The value object allows control of all operations upon
-the value as well as how compared values are treated, both on the SQL
-expression side as well as the Python value side.   Replacing the
-previous ``CaseInsensitiveComparator`` class with a new
-``CaseInsensitiveWord`` class::
-
-    class CaseInsensitiveWord(Comparator):
-        "Hybrid value representing a lower case representation of a word."
-
-        def __init__(self, word):
-            if isinstance(word, basestring):
-                self.word = word.lower()
-            elif isinstance(word, CaseInsensitiveWord):
-                self.word = word.word
-            else:
-                self.word = func.lower(word)
-
-        def operate(self, op, other):
-            if not isinstance(other, CaseInsensitiveWord):
-                other = CaseInsensitiveWord(other)
-            return op(self.word, other.word)
-
-        def __clause_element__(self):
-            return self.word
-
-        def __str__(self):
-            return self.word
-
-        key = 'word'
-        "Label to apply to Query tuple results"
-
-Above, the ``CaseInsensitiveWord`` object represents ``self.word``,
-which may be a SQL function, or may be a Python native.   By
-overriding ``operate()`` and ``__clause_element__()`` to work in terms
-of ``self.word``, all comparison operations will work against the
-"converted" form of ``word``, whether it be SQL side or Python side.
-Our ``SearchWord`` class can now deliver the ``CaseInsensitiveWord``
-object unconditionally from a single hybrid call::
-
-    class SearchWord(Base):
-        __tablename__ = 'searchword'
-        id = Column(Integer, primary_key=True)
-        word = Column(String(255), nullable=False)
-
-        @hybrid_property
-        def word_insensitive(self):
-            return CaseInsensitiveWord(self.word)
-
-The ``word_insensitive`` attribute now has case-insensitive comparison
-behavior universally, including SQL expression vs. Python expression
-(note the Python value is converted to lower case on the Python side
-here)::
-
-    >>> print Session().query(SearchWord).filter_by(word_insensitive="Trucks")
-    SELECT searchword.id AS searchword_id, searchword.word AS searchword_word
-    FROM searchword
-    WHERE lower(searchword.word) = :lower_1
-
-SQL expression versus SQL expression::
-
-    >>> sw1 = aliased(SearchWord)
-    >>> sw2 = aliased(SearchWord)
-    >>> print Session().query(
-    ...                    sw1.word_insensitive,
-    ...                    sw2.word_insensitive).\\
-    ...                        filter(
-    ...                            sw1.word_insensitive > sw2.word_insensitive
-    ...                        )
-    SELECT lower(searchword_1.word) AS lower_1,
-    lower(searchword_2.word) AS lower_2
-    FROM searchword AS searchword_1, searchword AS searchword_2
-    WHERE lower(searchword_1.word) > lower(searchword_2.word)
-
-Python only expression::
-
-    >>> ws1 = SearchWord(word="SomeWord")
-    >>> ws1.word_insensitive == "sOmEwOrD"
-    True
-    >>> ws1.word_insensitive == "XOmEwOrX"
-    False
-    >>> print ws1.word_insensitive
-    someword
-
-The Hybrid Value pattern is very useful for any kind of value that may
-have multiple representations, such as timestamps, time deltas, units
-of measurement, currencies and encrypted passwords.

-.. _hybrid_transformers:
-
-Building Transformers
-----------------------
-
-A *transformer* is an object which can receive a :class:`.Query`
-object and return a new one.   The :class:`.Query` object includes a
-method :meth:`.with_transformation` that returns a new :class:`.Query`
-transformed by the given function.
-
-We can combine this with the :class:`.Comparator` class to produce one type
-of recipe which can both set up the FROM clause of a query as well as assign
-filtering criterion.
-
-Consider a mapped class ``Node``, which assembles using adjacency list
-into a hierarchical tree pattern::
-
-    from sqlalchemy import Column, Integer, ForeignKey
-    from sqlalchemy.orm import relationship
-    from sqlalchemy.ext.declarative import declarative_base
-    Base = declarative_base()
-
-    class Node(Base):
-        __tablename__ = 'node'
-        id =Column(Integer, primary_key=True)
-        parent_id = Column(Integer, ForeignKey('node.id'))
-        parent = relationship("Node", remote_side=id)
-
-Suppose we wanted to add an accessor ``grandparent``.  This would
-return the ``parent`` of ``Node.parent``.  When we have an instance of
-``Node``, this is simple::
-
-    from sqlalchemy.ext.hybrid import hybrid_property
-
-    class Node(Base):
-        # ...
-
-        @hybrid_property
-        def grandparent(self):
-            return self.parent.parent
-
-For the expression, things are not so clear.   We'd need to construct
-a :class:`.Query` where we :meth:`~.Query.join` twice along
-``Node.parent`` to get to the ``grandparent``.   We can instead return
-a transforming callable that we'll combine with the
-:class:`.Comparator` class to receive any :class:`.Query` object, and
-return a new one that's joined to the ``Node.parent`` attribute and
-filtered based on the given criterion::
-
-    from sqlalchemy.ext.hybrid import Comparator
-
-    class GrandparentTransformer(Comparator):
-        def operate(self, op, other):
-            def transform(q):
-                cls = self.__clause_element__()
-                parent_alias = aliased(cls)
-                return q.join(parent_alias, cls.parent).\\
-                            filter(op(parent_alias.parent, other))
-            return transform
-
-    Base = declarative_base()
-
-    class Node(Base):
-        __tablename__ = 'node'
-        id =Column(Integer, primary_key=True)
-        parent_id = Column(Integer, ForeignKey('node.id'))
-        parent = relationship("Node", remote_side=id)
-
-        @hybrid_property
-        def grandparent(self):
-            return self.parent.parent
-
-        @grandparent.comparator
-        def grandparent(cls):
-            return GrandparentTransformer(cls)
-
-The ``GrandparentTransformer`` overrides the core
-:meth:`.Operators.operate` method at the base of the
-:class:`.Comparator` hierarchy to return a query-transforming
-callable, which then runs the given comparison operation in a
-particular context. Such as, in the example above, the ``operate``
-method is called, given the :attr:`.Operators.eq` callable as well as
-the right side of the comparison ``Node(id=5)``.  A function
-``transform`` is then returned which will transform a :class:`.Query`
-first to join to ``Node.parent``, then to compare ``parent_alias``
-using :attr:`.Operators.eq` against the left and right sides, passing
-into :class:`.Query.filter`:
-
-.. sourcecode:: pycon+sql
-
-    >>> from sqlalchemy.orm import Session
-    >>> session = Session()
-    {sql}>>> session.query(Node).\\
-    ...        with_transformation(Node.grandparent==Node(id=5)).\\
-    ...        all()
-    SELECT node.id AS node_id, node.parent_id AS node_parent_id
-    FROM node JOIN node AS node_1 ON node_1.id = node.parent_id
-    WHERE :param_1 = node_1.parent_id
-    {stop}
-
-We can modify the pattern to be more verbose but flexible by separating
-the "join" step from the "filter" step.  The tricky part here is ensuring
-that successive instances of ``GrandparentTransformer`` use the same
-:class:`.AliasedClass` object against ``Node``.  Below we use a simple
-memoizing approach that associates a ``GrandparentTransformer``
-with each class::
-
-    class Node(Base):
-
-        # ...
-
-        @grandparent.comparator
-        def grandparent(cls):
-            # memoize a GrandparentTransformer
-            # per class
-            if '_gp' not in cls.__dict__:
-                cls._gp = GrandparentTransformer(cls)
-            return cls._gp
-
-    class GrandparentTransformer(Comparator):
-
-        def __init__(self, cls):
-            self.parent_alias = aliased(cls)
-
-        @property
-        def join(self):
-            def go(q):
-                return q.join(self.parent_alias, Node.parent)
-            return go
-
-        def operate(self, op, other):
-            return op(self.parent_alias.parent, other)
-
-.. sourcecode:: pycon+sql
-
-    {sql}>>> session.query(Node).\\
-    ...            with_transformation(Node.grandparent.join).\\
-    ...            filter(Node.grandparent==Node(id=5))
-    SELECT node.id AS node_id, node.parent_id AS node_parent_id
-    FROM node JOIN node AS node_1 ON node_1.id = node.parent_id
-    WHERE :param_1 = node_1.parent_id
-    {stop}
-
-The "transformer" pattern is an experimental pattern that starts
-to make usage of some functional programming paradigms.
-While it's only recommended for advanced and/or patient developers,
-there's probably a whole lot of amazing things it can be used for.

-Establishing Mutability on Scalar Column Values
-===============================================
-
-A typical example of a "mutable" structure is a Python dictionary.
-Following the example introduced in :ref:`types_toplevel`, we
-begin with a custom type that marshals Python dictionaries into
-JSON strings before being persisted::
-
-    from sqlalchemy.types import TypeDecorator, VARCHAR
-    import json
-
-    class JSONEncodedDict(TypeDecorator):
-        "Represents an immutable structure as a json-encoded string."
-
-        impl = VARCHAR
-
-        def process_bind_param(self, value, dialect):
-            if value is not None:
-                value = json.dumps(value)
-            return value
-
-        def process_result_value(self, value, dialect):
-            if value is not None:
-                value = json.loads(value)
-            return value
-
-The usage of ``json`` is only for the purposes of example. The
-:mod:`sqlalchemy.ext.mutable` extension can be used
-with any type whose target Python type may be mutable, including
-:class:`.PickleType`, :class:`.postgresql.ARRAY`, etc.
-
-When using the :mod:`sqlalchemy.ext.mutable` extension, the value itself
-tracks all parents which reference it.  Below, we illustrate the a simple
-version of the :class:`.MutableDict` dictionary object, which applies
-the :class:`.Mutable` mixin to a plain Python dictionary::
-

-
-The above dictionary class takes the approach of subclassing the Python
-built-in ``dict`` to produce a dict
-subclass which routes all mutation events through ``__setitem__``.  There are
-variants on this approach, such as subclassing ``UserDict.UserDict`` or
-``collections.MutableMapping``; the part that's important to this example is
-that the :meth:`.Mutable.changed` method is called whenever an in-place
-change to the datastructure takes place.
-
-We also redefine the :meth:`.Mutable.coerce` method which will be used to
-convert any values that are not instances of ``MutableDict``, such
-as the plain dictionaries returned by the ``json`` module, into the
-appropriate type.  Defining this method is optional; we could just as well
-created our ``JSONEncodedDict`` such that it always returns an instance
-of ``MutableDict``, and additionally ensured that all calling code
-uses ``MutableDict`` explicitly.  When :meth:`.Mutable.coerce` is not
-overridden, any values applied to a parent object which are not instances
-of the mutable type will raise a ``ValueError``.
-
-Our new ``MutableDict`` type offers a class method
-:meth:`~.Mutable.as_mutable` which we can use within column metadata
-to associate with types. This method grabs the given type object or
-class and associates a listener that will detect all future mappings
-of this type, applying event listening instrumentation to the mapped
-attribute. Such as, with classical table metadata::
-
-    from sqlalchemy import Table, Column, Integer
-
-    my_data = Table('my_data', metadata,
-        Column('id', Integer, primary_key=True),
-        Column('data', MutableDict.as_mutable(JSONEncodedDict))
-    )
-
-Above, :meth:`~.Mutable.as_mutable` returns an instance of ``JSONEncodedDict``
-(if the type object was not an instance already), which will intercept any
-attributes which are mapped against this type.  Below we establish a simple
-mapping against the ``my_data`` table::
-
-    from sqlalchemy import mapper
-
-    class MyDataClass(object):
-        pass
-
-    # associates mutation listeners with MyDataClass.data
-    mapper(MyDataClass, my_data)
-
-The ``MyDataClass.data`` member will now be notified of in place changes
-to its value.
-
-There's no difference in usage when using declarative::
-
-    from sqlalchemy.ext.declarative import declarative_base
-
-    Base = declarative_base()
-
-    class MyDataClass(Base):
-        __tablename__ = 'my_data'
-        id = Column(Integer, primary_key=True)
-        data = Column(MutableDict.as_mutable(JSONEncodedDict))
-
-Any in-place changes to the ``MyDataClass.data`` member
-will flag the attribute as "dirty" on the parent object::
-
-    >>> from sqlalchemy.orm import Session
-
-    >>> sess = Session()
-    >>> m1 = MyDataClass(data={'value1':'foo'})
-    >>> sess.add(m1)
-    >>> sess.commit()
-
-    >>> m1.data['value1'] = 'bar'
-    >>> assert m1 in sess.dirty
-    True
-
-The ``MutableDict`` can be associated with all future instances
-of ``JSONEncodedDict`` in one step, using
-:meth:`~.Mutable.associate_with`.  This is similar to
-:meth:`~.Mutable.as_mutable` except it will intercept all occurrences
-of ``MutableDict`` in all mappings unconditionally, without
-the need to declare it individually::
-
-    MutableDict.associate_with(JSONEncodedDict)
-
-    class MyDataClass(Base):
-        __tablename__ = 'my_data'
-        id = Column(Integer, primary_key=True)
-        data = Column(JSONEncodedDict)
-
-
-Supporting Pickling
---------------------
-
-The key to the :mod:`sqlalchemy.ext.mutable` extension relies upon the
-placement of a ``weakref.WeakKeyDictionary`` upon the value object, which
-stores a mapping of parent mapped objects keyed to the attribute name under
-which they are associated with this value. ``WeakKeyDictionary`` objects are
-not picklable, due to the fact that they contain weakrefs and function
-callbacks. In our case, this is a good thing, since if this dictionary were
-picklable, it could lead to an excessively large pickle size for our value
-objects that are pickled by themselves outside of the context of the parent.
-The developer responsibility here is only to provide a ``__getstate__`` method
-that excludes the :meth:`~MutableBase._parents` collection from the pickle
-stream::
-
-    class MyMutableType(Mutable):
-        def __getstate__(self):
-            d = self.__dict__.copy()
-            d.pop('_parents', None)
-            return d
-
-With our dictionary example, we need to return the contents of the dict itself
-(and also restore them on __setstate__)::
-
-    class MutableDict(Mutable, dict):
-        # ....
-
-        def __getstate__(self):
-            return dict(self)
-
-        def __setstate__(self, state):
-            self.update(state)
-
-In the case that our mutable value object is pickled as it is attached to one
-or more parent objects that are also part of the pickle, the :class:`.Mutable`
-mixin will re-establish the :attr:`.Mutable._parents` collection on each value
-object as the owning parents themselves are unpickled.
-
-.. _mutable_composites:
-
-Establishing Mutability on Composites
-=====================================
-
-Composites are a special ORM feature which allow a single scalar attribute to
-be assigned an object value which represents information "composed" from one
-or more columns from the underlying mapped table. The usual example is that of
-a geometric "point", and is introduced in :ref:`mapper_composite`.
-
-.. versionchanged:: 0.7
-    The internals of :func:`.orm.composite` have been
-    greatly simplified and in-place mutation detection is no longer enabled by
-    default; instead, the user-defined value must detect changes on its own and
-    propagate them to all owning parents. The :mod:`sqlalchemy.ext.mutable`
-    extension provides the helper class :class:`.MutableComposite`, which is a
-    slight variant on the :class:`.Mutable` class.
-
-As is the case with :class:`.Mutable`, the user-defined composite class
-subclasses :class:`.MutableComposite` as a mixin, and detects and delivers
-change events to its parents via the :meth:`.MutableComposite.changed` method.
-In the case of a composite class, the detection is usually via the usage of
-Python descriptors (i.e. ``@property``), or alternatively via the special
-Python method ``__setattr__()``. Below we expand upon the ``Point`` class
-introduced in :ref:`mapper_composite` to subclass :class:`.MutableComposite`
-and to also route attribute set events via ``__setattr__`` to the
-:meth:`.MutableComposite.changed` method::
-
-    from sqlalchemy.ext.mutable import MutableComposite
-
-    class Point(MutableComposite):
-        def __init__(self, x, y):
-            self.x = x
-            self.y = y
-
-        def __setattr__(self, key, value):
-            "Intercept set events"
-
-            # set the attribute
-            object.__setattr__(self, key, value)
-
-            # alert all parents to the change
-            self.changed()
-
-        def __composite_values__(self):
-            return self.x, self.y
-
-        def __eq__(self, other):
-            return isinstance(other, Point) and \\
-                other.x == self.x and \\
-                other.y == self.y
-
-        def __ne__(self, other):
-            return not self.__eq__(other)
-
-The :class:`.MutableComposite` class uses a Python metaclass to automatically
-establish listeners for any usage of :func:`.orm.composite` that specifies our
-``Point`` type. Below, when ``Point`` is mapped to the ``Vertex`` class,
-listeners are established which will route change events from ``Point``
-objects to each of the ``Vertex.start`` and ``Vertex.end`` attributes::
-
-    from sqlalchemy.orm import composite, mapper
-    from sqlalchemy import Table, Column
-
-    vertices = Table('vertices', metadata,
-        Column('id', Integer, primary_key=True),
-        Column('x1', Integer),
-        Column('y1', Integer),
-        Column('x2', Integer),
-        Column('y2', Integer),
-        )
-
-    class Vertex(object):
-        pass
-
-    mapper(Vertex, vertices, properties={
-        'start': composite(Point, vertices.c.x1, vertices.c.y1),
-        'end': composite(Point, vertices.c.x2, vertices.c.y2)
-    })
-
-Any in-place changes to the ``Vertex.start`` or ``Vertex.end`` members
-will flag the attribute as "dirty" on the parent object::
-
-    >>> from sqlalchemy.orm import Session
-
-    >>> sess = Session()
-    >>> v1 = Vertex(start=Point(3, 4), end=Point(12, 15))
-    >>> sess.add(v1)
-    >>> sess.commit()
-
-    >>> v1.end.x = 8
-    >>> assert v1 in sess.dirty
-    True
-
-Coercing Mutable Composites
----------------------------
-
-The :meth:`.MutableBase.coerce` method is also supported on composite types.
-In the case of :class:`.MutableComposite`, the :meth:`.MutableBase.coerce`
-method is only called for attribute set operations, not load operations.
-Overriding the :meth:`.MutableBase.coerce` method is essentially equivalent
-to using a :func:`.validates` validation routine for all attributes which
-make use of the custom composite type::
-
-    class Point(MutableComposite):
-        # other Point methods
-        # ...
-
-        def coerce(cls, key, value):
-            if isinstance(value, tuple):
-                value = Point(*value)
-            elif not isinstance(value, Point):
-                raise ValueError("tuple or Point expected")
-            return value
-
-.. versionadded:: 0.7.10,0.8.0b2
-    Support for the :meth:`.MutableBase.coerce` method in conjunction with
-    objects of type :class:`.MutableComposite`.
-
-Supporting Pickling
---------------------
-
-As is the case with :class:`.Mutable`, the :class:`.MutableComposite` helper
-class uses a ``weakref.WeakKeyDictionary`` available via the
-:meth:`MutableBase._parents` attribute which isn't picklable. If we need to
-pickle instances of ``Point`` or its owning class ``Vertex``, we at least need
-to define a ``__getstate__`` that doesn't include the ``_parents`` dictionary.
-Below we define both a ``__getstate__`` and a ``__setstate__`` that package up
-the minimal form of our ``Point`` class::
-
-    class Point(MutableComposite):
-        # ...
-
-        def __getstate__(self):
-            return self.x, self.y
-
-        def __setstate__(self, state):
-            self.x, self.y = state
-
-As with :class:`.Mutable`, the :class:`.MutableComposite` augments the
-pickling process of the parent's object-relational state so that the
-:meth:`MutableBase._parents` collection is restored to all ``Point`` objects.

-"""A custom list that manages index/position information for contained
-elements.
-
-:author: Jason Kirtland
-
-``orderinglist`` is a helper for mutable ordered relationships.  It will
-intercept list operations performed on a :func:`.relationship`-managed
-collection and
-automatically synchronize changes in list position onto a target scalar
-attribute.
-
-Example: A ``slide`` table, where each row refers to zero or more entries
-in a related ``bullet`` table.   The bullets within a slide are
-displayed in order based on the value of the ``position`` column in the
-``bullet`` table.   As entries are reordered in memory, the value of the
-``position`` attribute should be updated to reflect the new sort order::
-
-
-    Base = declarative_base()
-
-    class Slide(Base):
-        __tablename__ = 'slide'
-
-        id = Column(Integer, primary_key=True)
-        name = Column(String)
-
-        bullets = relationship("Bullet", order_by="Bullet.position")
-
-    class Bullet(Base):
-        __tablename__ = 'bullet'
-        id = Column(Integer, primary_key=True)
-        slide_id = Column(Integer, ForeignKey('slide.id'))
-        position = Column(Integer)
-        text = Column(String)
-
-The standard relationship mapping will produce a list-like attribute on each
-``Slide`` containing all related ``Bullet`` objects,
-but coping with changes in ordering is not handled automatically.
-When appending a ``Bullet`` into ``Slide.bullets``, the ``Bullet.position``
-attribute will remain unset until manually assigned.   When the ``Bullet``
-is inserted into the middle of the list, the following ``Bullet`` objects
-will also need to be renumbered.
-
-The :class:`.OrderingList` object automates this task, managing the
-``position`` attribute on all ``Bullet`` objects in the collection.  It is
-constructed using the :func:`.ordering_list` factory::
-
-    from sqlalchemy.ext.orderinglist import ordering_list
-
-    Base = declarative_base()
-
-    class Slide(Base):
-        __tablename__ = 'slide'
-
-        id = Column(Integer, primary_key=True)
-        name = Column(String)
-
-        bullets = relationship("Bullet", order_by="Bullet.position",
-                                collection_class=ordering_list('position'))
-
-    class Bullet(Base):
-        __tablename__ = 'bullet'
-        id = Column(Integer, primary_key=True)
-        slide_id = Column(Integer, ForeignKey('slide.id'))
-        position = Column(Integer)
-        text = Column(String)
-
-With the above mapping the ``Bullet.position`` attribute is managed::
-
-    s = Slide()
-    s.bullets.append(Bullet())
-    s.bullets.append(Bullet())
-    s.bullets[1].position
-    >>> 1
-    s.bullets.insert(1, Bullet())
-    s.bullets[2].position
-    >>> 2
-
-The :class:`.OrderingList` construct only works with **changes** to a collection,
-and not the initial load from the database, and requires that the list be
-sorted when loaded.  Therefore, be sure to
-specify ``order_by`` on the :func:`.relationship` against the target ordering
-attribute, so that the ordering is correct when first loaded.
-
-.. warning::
-
-  :class:`.OrderingList` only provides limited functionality when a primary
-  key column or unique column is the target of the sort.  Operations
-  that are unsupported or are problematic include:
-
-    * two entries must trade values.  This is not supported directly in the
-      case of a primary key or unique constraint because it means at least
-      one row would need to be temporarily removed first, or changed to
-      a third, neutral value while the switch occurs.
-
-    * an entry must be deleted in order to make room for a new entry.
-      SQLAlchemy's unit of work performs all INSERTs before DELETEs within a
-      single flush.  In the case of a primary key, it will trade
-      an INSERT/DELETE of the same primary key for an UPDATE statement in order
-      to lessen the impact of this lmitation, however this does not take place
-      for a UNIQUE column.
-      A future feature will allow the "DELETE before INSERT" behavior to be
-      possible, allevating this limitation, though this feature will require
-      explicit configuration at the mapper level for sets of columns that
-      are to be handled in this way.
-
-:func:`.ordering_list` takes the name of the related object's ordering attribute as
-an argument.  By default, the zero-based integer index of the object's
-position in the :func:`.ordering_list` is synchronized with the ordering attribute:
-index 0 will get position 0, index 1 position 1, etc.  To start numbering at 1
-or some other integer, provide ``count_from=1``.

-          If omitted, Python list indexes are used for the attribute values.
-          Two basic pre-built numbering functions are provided in this module:

-          variety of dangerous unexpected database writes.
-
-          SQLAlchemy will add instances to the list via append() when your
-          object loads.  If for some reason the result set from the database
-          skips a step in the ordering (say, row '1' is missing but you get

-          concurrent modification error.
-

-"""Serializer/Deserializer objects for usage with SQLAlchemy query structures,
-allowing "contextual" deserialization.
-
-Any SQLAlchemy query structure, either based on sqlalchemy.sql.*
-or sqlalchemy.orm.* can be used.  The mappers, Tables, Columns, Session
-etc. which are referenced by the structure are not persisted in serialized
-form, but are instead re-associated with the query structure
-when it is deserialized.
-
-Usage is nearly the same as that of the standard Python pickle module::
-
-    from sqlalchemy.ext.serializer import loads, dumps
-    metadata = MetaData(bind=some_engine)
-    Session = scoped_session(sessionmaker())
-
-    # ... define mappers
-
-    query = Session.query(MyClass).filter(MyClass.somedata=='foo').order_by(MyClass.sortkey)
-
-    # pickle the query
-    serialized = dumps(query)
-
-    # unpickle.  Pass in metadata + scoped_session
-    query2 = loads(serialized, metadata, Session)
-
-    print query2.all()
-
-Similar restrictions as when using raw pickle apply; mapped classes must be
-themselves be pickleable, meaning they are importable from a module-level
-namespace.
-
-The serializer module is only appropriate for query structures.  It is not
-needed for:
-
-* instances of user-defined classes.   These contain no references to engines,
-  sessions or expression constructs in the typical case and can be serialized
-  directly.
-
-* Table metadata that is to be loaded entirely from the serialized structure
-  (i.e. is not already declared in the application).   Regular
-  pickle.loads()/dumps() can be used to fully dump any ``MetaData`` object,
-  typically one which was reflected from an existing database at some previous
-  point in time.  The serializer module is specifically for the opposite case,
-  where the Table metadata is already present in memory.

-"""The inspection module provides the :func:`.inspect` function,
-which delivers runtime information about a wide variety
-of SQLAlchemy objects, both within the Core as well as the
-ORM.
-
-The :func:`.inspect` function is the entry point to SQLAlchemy's
-public API for viewing the configuration and construction
-of in-memory objects.   Depending on the type of object
-passed to :func:`.inspect`, the return value will either be
-a related object which provides a known interface, or in many
-cases it will return the object itself.
-
-The rationale for :func:`.inspect` is twofold.  One is that
-it replaces the need to be aware of a large variety of "information
-getting" functions in SQLAlchemy, such as :meth:`.Inspector.from_engine`,
-:func:`.orm.attributes.instance_state`, :func:`.orm.class_mapper`,
-and others.    The other is that the return value of :func:`.inspect`
-is guaranteed to obey a documented API, thus allowing third party
-tools which build on top of SQLAlchemy configurations to be constructed
-in a forwards-compatible way.
-
-.. versionadded:: 0.8 The :func:`.inspect` system is introduced
-   as of version 0.8.

-
-    All of the standard connection :class:`~sqlalchemy.pool.Pool` types can
-    accept event listeners for key connection lifecycle events:
-    creation, pool check-out and check-in.  There are no events fired
-    when a connection closes.
-
-    For any given DB-API connection, there will be one ``connect``
-    event, `n` number of ``checkout`` events, and either `n` or `n - 1`
-    ``checkin`` events.  (If a ``Connection`` is detached from its
-    pool via the ``detach()`` method, it won't be checked back in.)
-
-    These are low-level events for low-level objects: raw Python
-    DB-API connections, without the conveniences of the SQLAlchemy
-    ``Connection`` wrapper, ``Dialect`` services or ``ClauseElement``
-    execution.  If you execute SQL through the connection, explicitly
-    closing all cursors and other resources is recommended.
-
-    Events also receive a ``_ConnectionRecord``, a long-lived internal
-    ``Pool`` object that basically represents a "slot" in the
-    connection pool.  ``_ConnectionRecord`` objects have one public
-    attribute of note: ``info``, a dictionary whose contents are
-    scoped to the lifetime of the DB-API connection managed by the
-    record.  You can use this shared storage area however you like.
-
-    There is no need to subclass ``PoolListener`` to handle events.
-    Any class that implements one or more of these methods can be used
-    as a pool listener.  The ``Pool`` will inspect the methods
-    provided by a listener object and add the listener to one or more
-    internal event queues based on its capabilities.  In terms of
-    efficiency and function call overhead, you're much better off only
-    providing implementations for the hooks you'll be using.

-"""Support for collections of mapped entities.
-
-The collections package supplies the machinery used to inform the ORM of
-collection membership changes.  An instrumentation via decoration approach is
-used, allowing arbitrary types (including built-ins) to be used as entity
-collections without requiring inheritance from a base class.
-
-Instrumentation decoration relays membership change events to the
-:class:`.CollectionAttributeImpl` that is currently managing the collection.
-The decorators observe function call arguments and return values, tracking
-entities entering or leaving the collection.  Two decorator approaches are
-provided.  One is a bundle of generic decorators that map function arguments
-and return values to events::
-
-  from sqlalchemy.orm.collections import collection
-  class MyClass(object):
-      # ...
-
-      @collection.adds(1)
-      def store(self, item):
-          self.data.append(item)
-
-      @collection.removes_return()
-      def pop(self):
-          return self.data.pop()
-
-
-The second approach is a bundle of targeted decorators that wrap appropriate
-append and remove notifiers around the mutation methods present in the
-standard Python ``list``, ``set`` and ``dict`` interfaces.  These could be
-specified in terms of generic decorator recipes, but are instead hand-tooled
-for increased efficiency.  The targeted decorators occasionally implement
-adapter-like behavior, such as mapping bulk-set methods (``extend``,
-``update``, ``__setslice__``, etc.) into the series of atomic mutation events
-that the ORM requires.
-
-The targeted decorators are used internally for automatic instrumentation of
-entity collection classes.  Every collection class goes through a
-transformation process roughly like so:
-
-1. If the class is a built-in, substitute a trivial sub-class
-2. Is this class already instrumented?
-3. Add in generic decorators
-4. Sniff out the collection interface through duck-typing
-5. Add targeted decoration to any undecorated interface method
-
-This process modifies the class at runtime, decorating methods and adding some
-bookkeeping properties.  This isn't possible (or desirable) for built-in
-classes like ``list``, so trivial sub-classes are substituted to hold
-decoration::
-
-  class InstrumentedList(list):
-      pass
-
-Collection classes can be specified in ``relationship(collection_class=)`` as
-types or a function that returns an instance.  Collection classes are
-inspected and instrumented during the mapper compilation phase.  The
-collection_class callable will be executed once to produce a specimen
-instance, and the type of that specimen will be instrumented.  Functions that
-return built-in types like ``lists`` will be adapted to produce instrumented
-instances.
-
-When extending a known type like ``list``, additional decorations are not
-generally not needed.  Odds are, the extension method will delegate to a
-method that's already instrumented.  For example::
-
-  class QueueIsh(list):
-     def push(self, item):
-         self.append(item)
-     def shift(self):
-         return self.pop(0)
-
-There's no need to decorate these methods.  ``append`` and ``pop`` are already
-instrumented as part of the ``list`` interface.  Decorating them would fire
-duplicate events, which should be avoided.
-
-The targeted decoration tries not to rely on other methods in the underlying
-collection class, but some are unavoidable.  Many depend on 'read' methods
-being present to properly instrument a 'write', for example, ``__setitem__``
-needs ``__getitem__``.  "Bulk" methods like ``update`` and ``extend`` may also
-reimplemented in terms of atomic appends and removes, so the ``extend``
-decoration will actually perform many ``append`` operations and not call the
-underlying method at all.
-
-Tight control over bulk operation and the firing of events is also possible by
-implementing the instrumentation internally in your methods.  The basic
-instrumentation package works under the general assumption that collection
-mutation will not raise unusual exceptions.  If you want to closely
-orchestrate append and remove events with exception management, internal
-instrumentation may be the answer.  Within your method,
-``collection_adapter(self)`` will retrieve an object that you can use for
-explicit control over triggering append and remove events.
-
-The owning object and :class:`.CollectionAttributeImpl` are also reachable
-through the adapter, allowing for some very sophisticated behavior.

-class MapperExtension(object):
-    """Base implementation for :class:`.Mapper` event hooks.
-
-    .. note::
-
-       :class:`.MapperExtension` is deprecated.   Please
-       refer to :func:`.event.listen` as well as
-       :class:`.MapperEvents`.
-
-    New extension classes subclass :class:`.MapperExtension` and are specified
-    using the ``extension`` mapper() argument, which is a single
-    :class:`.MapperExtension` or a list of such::
-
-        from sqlalchemy.orm.interfaces import MapperExtension
-
-        class MyExtension(MapperExtension):
-            def before_insert(self, mapper, connection, instance):
-                print "instance %s before insert !" % instance
-
-        m = mapper(User, users_table, extension=MyExtension())
-
-    A single mapper can maintain a chain of ``MapperExtension``
-    objects. When a particular mapping event occurs, the
-    corresponding method on each ``MapperExtension`` is invoked
-    serially, and each method has the ability to halt the chain
-    from proceeding further::
-
-        m = mapper(User, users_table, extension=[ext1, ext2, ext3])
-
-    Each ``MapperExtension`` method returns the symbol
-    EXT_CONTINUE by default.   This symbol generally means "move
-    to the next ``MapperExtension`` for processing".  For methods
-    that return objects like translated rows or new object
-    instances, EXT_CONTINUE means the result of the method
-    should be ignored.   In some cases it's required for a
-    default mapper activity to be performed, such as adding a
-    new instance to a result list.
-
-    The symbol EXT_STOP has significance within a chain
-    of ``MapperExtension`` objects that the chain will be stopped
-    when this symbol is returned.  Like EXT_CONTINUE, it also
-    has additional significance in some cases that a default
-    mapper activity will not be performed.

-        redefinition of expression operator behavior.
-
-        In the example below we redefine :meth:`.PropComparator.operate`
-        to wrap both sides of an expression in ``func.lower()`` to produce
-        case-insensitive comparison::
-
-            from sqlalchemy.orm import comparable_property
-            from sqlalchemy.orm.interfaces import PropComparator
-            from sqlalchemy.sql import func
-            from sqlalchemy import Integer, String, Column
-            from sqlalchemy.ext.declarative import declarative_base
-
-            class CaseInsensitiveComparator(PropComparator):
-                def __clause_element__(self):
-                    return self.prop
-
-                def operate(self, op, other):
-                    return op(
-                        func.lower(self.__clause_element__()),
-                        func.lower(other)
-                    )
-
-            Base = declarative_base()
-
-            class SearchWord(Base):
-                __tablename__ = 'search_word'
-                id = Column(Integer, primary_key=True)
-                word = Column(String)
-                word_insensitive = comparable_property(lambda prop, mapper:
-                                CaseInsensitiveComparator(mapper.c.word, mapper)
-                            )
-
-
-        A mapping like the above allows the ``word_insensitive`` attribute
-        to render an expression like::
-
-            >>> print SearchWord.word_insensitive == "Trucks"
-            lower(search_word.word) = lower(:lower_1)
-
-        :param comparator_factory:
-          A PropComparator subclass or factory that defines operator behavior
-          for this property.
-
-        :param descriptor:
-          Optional when used in a ``properties={}`` declaration.  The Python
-          descriptor or property to layer comparison behavior on top of.
-
-          The like-named descriptor will be automatically retrieved from the
-          mapped class if left blank in a ``properties`` declaration.
-
-        """
-        self.descriptor = descriptor
-        self.comparator_factory = comparator_factory
-        self.doc = doc or (descriptor and descriptor.__doc__) or None
-        util.set_creation_order(self)
-
-    def _comparator_factory(self, mapper):
-        return self.comparator_factory(self, mapper)

-"""Defines SQLAlchemy's system of class instrumentation.
-
-This module is usually not directly visible to user applications, but
-defines a large part of the ORM's interactivity.
-
-instrumentation.py deals with registration of end-user classes
-for state tracking.   It interacts closely with state.py
-and attributes.py which establish per-instance and per-class-attribute
-instrumentation, respectively.
-
-The class instrumentation system can be customized on a per-class
-or global basis using the :mod:`sqlalchemy.ext.instrumentation`
-module, which provides the means to build and specify
-alternate instrumentation forms.
-
-.. versionchanged: 0.8
-   The instrumentation extension system was moved out of the
-   ORM and into the external :mod:`sqlalchemy.ext.instrumentation`
-   package.  When that package is imported, it installs
-   itself within sqlalchemy.orm so that its more comprehensive
-   resolution mechanics take effect.

-        This function is typically used behind the scenes

-        many of the usual :func:`.mapper` arguments are handled
-        by the Declarative extension itself, including ``class_``,
-        ``local_table``, ``properties``, and  ``inherits``.
-        Other options are passed to :func:`.mapper` using
-        the ``__mapper_args__`` class variable::
-
-           class MyClass(Base):

-        Explicit use of :func:`.mapper`
-        is often referred to as *classical mapping*.  The above

-
-            :ref:`classical_mapping` - discussion of direct usage of
-            :func:`.mapper`
-
-        :param class\_: The class to be mapped.  When using Declarative,
-          this argument is automatically passed as the declared class
-          itself.
-
-        :param local_table: The :class:`.Table` or other selectable
-           to which the class is mapped.  May be ``None`` if
-           this mapper inherits from another mapper using single-table
-           inheritance.   When using Declarative, this argument is
-           automatically passed by the extension, based on what
-           is configured via the ``__table__`` argument or via the
-           :class:`.Table` produced as a result of the ``__tablename__``
-           and :class:`.Column` arguments present.
-
-        :param always_refresh: If True, all query operations for this mapped
-           class will overwrite all data within object instances that already
-           exist within the session, erasing any in-memory changes with
-           whatever information was loaded from the database. Usage of this
-           flag is highly discouraged; as an alternative, see the method
-           :meth:`.Query.populate_existing`.
-
-        :param allow_partial_pks: Defaults to True.  Indicates that a
-           composite primary key with some NULL values should be considered as
-           possibly existing within the database. This affects whether a
-           mapper will assign an incoming row to an existing identity, as well
-           as if :meth:`.Session.merge` will check the database first for a
-           particular primary key value. A "partial primary key" can occur if
-           one has mapped to an OUTER JOIN, for example.
-
-        :param batch: Defaults to ``True``, indicating that save operations
-           of multiple entities can be batched together for efficiency.
-           Setting to False indicates
-           that an instance will be fully saved before saving the next
-           instance.  This is used in the extremely rare case that a
-           :class:`.MapperEvents` listener requires being called
-           in between individual row persistence operations.
-
-        :param column_prefix: A string which will be prepended
-           to the mapped attribute name when :class:`.Column`
-           objects are automatically assigned as attributes to the
-           mapped class.  Does not affect explicitly specified
-           column-based properties.
-
-           See the section :ref:`column_prefix` for an example.
-
-        :param concrete: If True, indicates this mapper should use concrete
-           table inheritance with its parent mapper.
-
-           See the section :ref:`concrete_inheritance` for an example.
-
-        :param confirm_deleted_rows: defaults to True; when a DELETE occurs
-          of one more more rows based on specific primary keys, a warning is
-          emitted when the number of rows matched does not equal the number
-          of rows expected.  This parameter may be set to False to handle the case
-          where database ON DELETE CASCADE rules may be deleting some of those
-          rows automatically.  The warning may be changed to an exception
-          in a future release.
-
-          .. versionadded:: 0.9.4 - added :paramref:`.mapper.confirm_deleted_rows`
-             as well as conditional matched row checking on delete.
-
-        :param eager_defaults: if True, the ORM will immediately fetch the
-          value of server-generated default values after an INSERT or UPDATE,
-          rather than leaving them as expired to be fetched on next access.
-          This can be used for event schemes where the server-generated values
-          are needed immediately before the flush completes.   By default,
-          this scheme will emit an individual ``SELECT`` statement per row
-          inserted or updated, which note can add significant performance
-          overhead.  However, if the
-          target database supports :term:`RETURNING`, the default values will be
-          returned inline with the INSERT or UPDATE statement, which can
-          greatly enhance performance for an application that needs frequent
-          access to just-generated server defaults.
-
-          .. versionchanged:: 0.9.0 The ``eager_defaults`` option can now
-             make use of :term:`RETURNING` for backends which support it.
-
-        :param exclude_properties: A list or set of string column names to
-          be excluded from mapping.
-
-          See :ref:`include_exclude_cols` for an example.
-
-        :param extension: A :class:`.MapperExtension` instance or
-           list of :class:`.MapperExtension` instances which will be applied
-           to all operations by this :class:`.Mapper`.  **Deprecated.**
-           Please see :class:`.MapperEvents`.
-
-        :param include_properties: An inclusive list or set of string column
-          names to map.
-
-          See :ref:`include_exclude_cols` for an example.
-
-        :param inherits: A mapped class or the corresponding :class:`.Mapper`
-          of one indicating a superclass to which this :class:`.Mapper`
-          should *inherit* from.   The mapped class here must be a subclass
-          of the other mapper's class.   When using Declarative, this argument
-          is passed automatically as a result of the natural class
-          hierarchy of the declared classes.
-
-          .. seealso::
-
-            :ref:`inheritance_toplevel`
-
-        :param inherit_condition: For joined table inheritance, a SQL
-           expression which will
-           define how the two tables are joined; defaults to a natural join
-           between the two tables.
-
-        :param inherit_foreign_keys: When ``inherit_condition`` is used and the
-           columns present are missing a :class:`.ForeignKey` configuration,
-           this parameter can be used to specify which columns are "foreign".
-           In most cases can be left as ``None``.
-
-        :param legacy_is_orphan: Boolean, defaults to ``False``.
-          When ``True``, specifies that "legacy" orphan consideration
-          is to be applied to objects mapped by this mapper, which means
-          that a pending (that is, not persistent) object is auto-expunged
-          from an owning :class:`.Session` only when it is de-associated
-          from *all* parents that specify a ``delete-orphan`` cascade towards
-          this mapper.  The new default behavior is that the object is auto-expunged
-          when it is de-associated with *any* of its parents that specify
-          ``delete-orphan`` cascade.  This behavior is more consistent with
-          that of a persistent object, and allows behavior to be consistent
-          in more scenarios independently of whether or not an orphanable
-          object has been flushed yet or not.
-
-          See the change note and example at :ref:`legacy_is_orphan_addition`
-          for more detail on this change.
-
-          .. versionadded:: 0.8 - the consideration of a pending object as
-            an "orphan" has been modified to more closely match the
-            behavior as that of persistent objects, which is that the object
-            is expunged from the :class:`.Session` as soon as it is
-            de-associated from any of its orphan-enabled parents.  Previously,
-            the pending object would be expunged only if de-associated
-            from all of its orphan-enabled parents. The new flag ``legacy_is_orphan``
-            is added to :func:`.orm.mapper` which re-establishes the
-            legacy behavior.
-
-        :param non_primary: Specify that this :class:`.Mapper` is in addition
-          to the "primary" mapper, that is, the one used for persistence.
-          The :class:`.Mapper` created here may be used for ad-hoc
-          mapping of the class to an alternate selectable, for loading
-          only.
-
-          :paramref:`.Mapper.non_primary` is not an often used option, but
-          is useful in some specific :func:`.relationship` cases.
-
-          .. seealso::
-
-              :ref:`relationship_non_primary_mapper`
-
-        :param order_by: A single :class:`.Column` or list of :class:`.Column`
-           objects for which selection operations should use as the default
-           ordering for entities.  By default mappers have no pre-defined
-           ordering.
-
-        :param passive_updates: Indicates UPDATE behavior of foreign key
-           columns when a primary key column changes on a joined-table
-           inheritance mapping.   Defaults to ``True``.
-
-           When True, it is assumed that ON UPDATE CASCADE is configured on
-           the foreign key in the database, and that the database will handle
-           propagation of an UPDATE from a source column to dependent columns
-           on joined-table rows.
-
-           When False, it is assumed that the database does not enforce
-           referential integrity and will not be issuing its own CASCADE
-           operation for an update.  The unit of work process will
-           emit an UPDATE statement for the dependent columns during a
-           primary key change.
-
-           .. seealso::
-
-               :ref:`passive_updates` - description of a similar feature as
-               used with :func:`.relationship`
-
-        :param polymorphic_on: Specifies the column, attribute, or
-          SQL expression used to determine the target class for an
-          incoming row, when inheriting classes are present.
-
-          This value is commonly a :class:`.Column` object that's
-          present in the mapped :class:`.Table`::
-
-            class Employee(Base):
-                __tablename__ = 'employee'
-
-                id = Column(Integer, primary_key=True)
-                discriminator = Column(String(50))
-
-                __mapper_args__ = {
-                    "polymorphic_on":discriminator,
-                    "polymorphic_identity":"employee"
-                }
-
-          It may also be specified
-          as a SQL expression, as in this example where we
-          use the :func:`.case` construct to provide a conditional
-          approach::
-
-            class Employee(Base):
-                __tablename__ = 'employee'
-
-                id = Column(Integer, primary_key=True)
-                discriminator = Column(String(50))
-
-                __mapper_args__ = {
-                    "polymorphic_on":case([
-                        (discriminator == "EN", "engineer"),
-                        (discriminator == "MA", "manager"),
-                    ], else_="employee"),
-                    "polymorphic_identity":"employee"
-                }
-
-          It may also refer to any attribute
-          configured with :func:`.column_property`, or to the
-          string name of one::
-
-                class Employee(Base):
-                    __tablename__ = 'employee'
-
-                    id = Column(Integer, primary_key=True)
-                    discriminator = Column(String(50))
-                    employee_type = column_property(
-                        case([
-                            (discriminator == "EN", "engineer"),
-                            (discriminator == "MA", "manager"),
-                        ], else_="employee")

-              ``polymorphic_on`` may be specified as a SQL expression,
-              or refer to any attribute configured with
-              :func:`.column_property`, or to the string name of one.
-
-          When setting ``polymorphic_on`` to reference an
-          attribute or expression that's not present in the
-          locally mapped :class:`.Table`, yet the value
-          of the discriminator should be persisted to the database,
-          the value of the
-          discriminator is not automatically set on new
-          instances; this must be handled by the user,
-          either through manual means or via event listeners.
-          A typical approach to establishing such a listener
-          looks like::
-
-                from sqlalchemy import event
-                from sqlalchemy.orm import object_mapper
-
-                @event.listens_for(Employee, "init", propagate=True)
-                def set_identity(instance, *arg, **kw):
-                    mapper = object_mapper(instance)
-                    instance.discriminator = mapper.polymorphic_identity
-
-          Where above, we assign the value of ``polymorphic_identity``
-          for the mapped class to the ``discriminator`` attribute,
-          thus persisting the value to the ``discriminator`` column
-          in the database.
-
-          .. seealso::
-
-            :ref:`inheritance_toplevel`
-
-        :param polymorphic_identity: Specifies the value which
-          identifies this particular class as returned by the
-          column expression referred to by the ``polymorphic_on``
-          setting.  As rows are received, the value corresponding
-          to the ``polymorphic_on`` column expression is compared
-          to this value, indicating which subclass should
-          be used for the newly reconstructed object.
-
-        :param properties: A dictionary mapping the string names of object
-           attributes to :class:`.MapperProperty` instances, which define the
-           persistence behavior of that attribute.  Note that :class:`.Column`
-           objects present in
-           the mapped :class:`.Table` are automatically placed into
-           ``ColumnProperty`` instances upon mapping, unless overridden.
-           When using Declarative, this argument is passed automatically,
-           based on all those :class:`.MapperProperty` instances declared
-           in the declared class body.
-
-        :param primary_key: A list of :class:`.Column` objects which define the
-           primary key to be used against this mapper's selectable unit.
-           This is normally simply the primary key of the ``local_table``, but
-           can be overridden here.
-
-        :param version_id_col: A :class:`.Column`
-           that will be used to keep a running version id of rows
-           in the table.  This is used to detect concurrent updates or
-           the presence of stale data in a flush.  The methodology is to
-           detect if an UPDATE statement does not match the last known
-           version id, a
-           :class:`~sqlalchemy.orm.exc.StaleDataError` exception is
-           thrown.
-           By default, the column must be of :class:`.Integer` type,
-           unless ``version_id_generator`` specifies an alternative version
-           generator.

-
-        :param version_id_generator: Define how new version ids should
-          be generated.  Defaults to ``None``, which indicates that
-          a simple integer counting scheme be employed.  To provide a custom
-          versioning scheme, provide a callable function of the form::
-
-              def generate_version(version):
-                  return next_version
-
-          Alternatively, server-side versioning functions such as triggers,
-          or programmatic versioning schemes outside of the version id generator
-          may be used, by specifying the value ``False``.
-          Please see :ref:`server_side_version_counter` for a discussion
-          of important points when using this option.

-            is considered to be a "read only" property; populating it
-            has no effect on the state of data, and it can only return
-            database state.   For this reason a column_property()'s value
-            is expired whenever the parent object is involved in a
-            flush, that is, has any kind of "dirty" state within a flush.
-            Setting this parameter to ``False`` will have the effect of
-            leaving any existing value present after the flush proceeds.
-            Note however that the :class:`.Session` with default expiration
-            settings still expires

-
-        **Simple Relationship Joins**
-
-        Consider a mapping between two classes ``User`` and ``Address``,
-        with a relationship ``User.addresses`` representing a collection
-        of ``Address`` objects associated with each ``User``.   The most common
-        usage of :meth:`~.Query.join` is to create a JOIN along this
-        relationship, using the ``User.addresses`` attribute as an indicator
-        for how this should occur::
-
-            q = session.query(User).join(User.addresses)
-
-        Where above, the call to :meth:`~.Query.join` along ``User.addresses``
-        will result in SQL equivalent to::
-
-            SELECT user.* FROM user JOIN address ON user.id = address.user_id
-
-        In the above example we refer to ``User.addresses`` as passed to
-        :meth:`~.Query.join` as the *on clause*, that is, it indicates
-        how the "ON" portion of the JOIN should be constructed.  For a
-        single-entity query such as the one above (i.e. we start by selecting
-        only from ``User`` and nothing else), the relationship can also be
-        specified by its string name::
-
-            q = session.query(User).join("addresses")
-
-        :meth:`~.Query.join` can also accommodate multiple
-        "on clause" arguments to produce a chain of joins, such as below
-        where a join across four related entities is constructed::
-
-            q = session.query(User).join("orders", "items", "keywords")
-
-        The above would be shorthand for three separate calls to
-        :meth:`~.Query.join`, each using an explicit attribute to indicate
-        the source entity::
-
-            q = session.query(User).\\
-                    join(User.orders).\\
-                    join(Order.items).\\
-                    join(Item.keywords)
-
-        **Joins to a Target Entity or Selectable**
-
-        A second form of :meth:`~.Query.join` allows any mapped entity
-        or core selectable construct as a target.   In this usage,
-        :meth:`~.Query.join` will attempt
-        to create a JOIN along the natural foreign key relationship between
-        two entities::
-
-            q = session.query(User).join(Address)
-
-        The above calling form of :meth:`~.Query.join` will raise an error if
-        either there are no foreign keys between the two entities, or if
-        there are multiple foreign key linkages between them.   In the
-        above calling form, :meth:`~.Query.join` is called upon to
-        create the "on clause" automatically for us.  The target can
-        be any mapped entity or selectable, such as a :class:`.Table`::
-
-            q = session.query(User).join(addresses_table)
-
-        **Joins to a Target with an ON Clause**
-
-        The third calling form allows both the target entity as well
-        as the ON clause to be passed explicitly.   Suppose for
-        example we wanted to join to ``Address`` twice, using
-        an alias the second time.  We use :func:`~sqlalchemy.orm.aliased`
-        to create a distinct alias of ``Address``, and join
-        to it using the ``target, onclause`` form, so that the
-        alias can be specified explicitly as the target along with
-        the relationship to instruct how the ON clause should proceed::
-
-            a_alias = aliased(Address)
-
-            q = session.query(User).\\
-                    join(User.addresses).\\
-                    join(a_alias, User.addresses).\\
-                    filter(Address.email_address=='ed@foo.com').\\
-                    filter(a_alias.email_address=='ed@bar.com')
-
-        Where above, the generated SQL would be similar to::
-
-            SELECT user.* FROM user
-                JOIN address ON user.id = address.user_id
-                JOIN address AS address_1 ON user.id=address_1.user_id
-                WHERE address.email_address = :email_address_1
-                AND address_1.email_address = :email_address_2
-
-        The two-argument calling form of :meth:`~.Query.join`
-        also allows us to construct arbitrary joins with SQL-oriented
-        "on clause" expressions, not relying upon configured relationships
-        at all.  Any SQL expression can be passed as the ON clause
-        when using the two-argument form, which should refer to the target
-        entity in some way as well as an applicable source entity::
-
-            q = session.query(User).join(Address, User.id==Address.user_id)
-
-        .. versionchanged:: 0.7
-            In SQLAlchemy 0.6 and earlier, the two argument form of
-            :meth:`~.Query.join` requires the usage of a tuple:
-            ``query(User).join((Address, User.id==Address.user_id))``\ .
-            This calling form is accepted in 0.7 and further, though
-            is not necessary unless multiple join conditions are passed to
-            a single :meth:`~.Query.join` call, which itself is also not
-            generally necessary as it is now equivalent to multiple
-            calls (this wasn't always the case).
-
-        **Advanced Join Targeting and Adaption**
-
-        There is a lot of flexibility in what the "target" can be when using
-        :meth:`~.Query.join`.   As noted previously, it also accepts
-        :class:`.Table` constructs and other selectables such as
-        :func:`.alias` and :func:`.select` constructs, with either the one
-        or two-argument forms::
-
-            addresses_q = select([Address.user_id]).\\
-                        where(Address.email_address.endswith("@bar.com")).\\
-                        alias()
-
-            q = session.query(User).\\
-                        join(addresses_q, addresses_q.c.user_id==User.id)
-
-        :meth:`~.Query.join` also features the ability to *adapt* a
-        :meth:`~sqlalchemy.orm.relationship` -driven ON clause to the target
-        selectable. Below we construct a JOIN from ``User`` to a subquery
-        against ``Address``, allowing the relationship denoted by
-        ``User.addresses`` to *adapt* itself to the altered target::
-
-            address_subq = session.query(Address).\\
-                            filter(Address.email_address == 'ed@foo.com').\\
-                            subquery()
-
-            q = session.query(User).join(address_subq, User.addresses)
-
-        Producing SQL similar to::
-
-            SELECT user.* FROM user
-                JOIN (
-                    SELECT address.id AS id,
-                            address.user_id AS user_id,
-                            address.email_address AS email_address
-                    FROM address
-                    WHERE address.email_address = :email_address_1
-                ) AS anon_1 ON user.id = anon_1.user_id
-
-        The above form allows one to fall back onto an explicit ON
-        clause at any time::
-
-            q = session.query(User).\\
-                    join(address_subq, User.id==address_subq.c.user_id)
-
-        **Controlling what to Join From**
-
-        While :meth:`~.Query.join` exclusively deals with the "right"
-        side of the JOIN, we can also control the "left" side, in those
-        cases where it's needed, using :meth:`~.Query.select_from`.
-        Below we construct a query against ``Address`` but can still
-        make usage of ``User.addresses`` as our ON clause by instructing
-        the :class:`.Query` to select first from the ``User``
-        entity::
-
-            q = session.query(Address).select_from(User).\\
-                            join(User.addresses).\\
-                            filter(User.name == 'ed')
-
-        Which will produce SQL similar to::
-
-            SELECT address.* FROM user
-                JOIN address ON user.id=address.user_id
-                WHERE user.name = :name_1
-
-        **Constructing Aliases Anonymously**
-
-        :meth:`~.Query.join` can construct anonymous aliases
-        using the ``aliased=True`` flag.  This feature is useful
-        when a query is being joined algorithmically, such as
-        when querying self-referentially to an arbitrary depth::
-
-            q = session.query(Node).\\
-                    join("children", "children", aliased=True)
-
-        When ``aliased=True`` is used, the actual "alias" construct
-        is not explicitly available.  To work with it, methods such as
-        :meth:`.Query.filter` will adapt the incoming entity to
-        the last join point::
-
-            q = session.query(Node).\\
-                    join("children", "children", aliased=True).\\
-                    filter(Node.name == 'grandchild 1')
-
-        When using automatic aliasing, the ``from_joinpoint=True``
-        argument can allow a multi-node join to be broken into
-        multiple calls to :meth:`~.Query.join`, so that
-        each path along the way can be further filtered::
-
-            q = session.query(Node).\\
-                    join("children", aliased=True).\\
-                    filter(Node.name='child 1').\\
-                    join("children", aliased=True, from_joinpoint=True).\\
-                    filter(Node.name == 'grandchild 1')
-
-        The filtering aliases above can then be reset back to the
-        original ``Node`` entity using :meth:`~.Query.reset_joinpoint`::
-
-            q = session.query(Node).\\
-                    join("children", "children", aliased=True).\\
-                    filter(Node.name == 'grandchild 1').\\
-                    reset_joinpoint().\\
-                    filter(Node.name == 'parent 1)
-
-        For an example of ``aliased=True``, see the distribution
-        example :ref:`examples_xmlpersistence` which illustrates
-        an XPath-like query system using algorithmic joins.
-
-        :param \*props: A collection of one or more join conditions,
-         each consisting of a relationship-bound attribute or string
-         relationship name representing an "on clause", or a single
-         target entity, or a tuple in the form of ``(target, onclause)``.
-         A special two-argument calling form of the form ``target, onclause``
-         is also accepted.
-        :param aliased=False: If True, indicate that the JOIN target should be
-         anonymously aliased.  Subsequent calls to :meth:`~.Query.filter`
-         and similar will adapt the incoming criterion to the target
-         alias, until :meth:`~.Query.reset_joinpoint` is called.
-        :param from_joinpoint=False: When using ``aliased=True``, a setting
-         of True here will cause the join to be from the most recent
-         joined target, rather than starting back from the original
-         FROM clauses of the query.

-        for corresponding mapped entities.
-
-        This method is similar to the :meth:`.Query.select_from`
-        method, in that it sets the FROM clause of the query.  However,
-        where :meth:`.Query.select_from` only affects what is placed
-        in the FROM, this method also applies the given selectable
-        to replace the FROM which the selected entities would normally
-        select from.
-
-        The given ``from_obj`` must be an instance of a :class:`.FromClause`,
-        e.g. a :func:`.select` or :class:`.Alias` construct.
-
-        An example would be a :class:`.Query` that selects ``User`` entities,
-        but uses :meth:`.Query.select_entity_from` to have the entities
-        selected from a :func:`.select` construct instead of the
-        base ``user`` table::
-
-            select_stmt = select([User]).where(User.id == 7)
-
-            q = session.query(User).\\
-                    select_entity_from(select_stmt).\\
-                    filter(User.name == 'ed')
-
-        The query generated will select ``User`` entities directly
-        from the given :func:`.select` construct, and will be::
-
-            SELECT anon_1.id AS anon_1_id, anon_1.name AS anon_1_name
-            FROM (SELECT "user".id AS id, "user".name AS name
-            FROM "user"
-            WHERE "user".id = :id_1) AS anon_1
-            WHERE anon_1.name = :name_1
-
-        Notice above that even the WHERE criterion was "adapted" such that
-        the ``anon_1`` subquery effectively replaces all references to the
-        ``user`` table, except for the one that it refers to internally.
-
-        Compare this to :meth:`.Query.select_from`, which as of
-        version 0.9, does not affect existing entities.  The
-        statement below::
-
-            q = session.query(User).\\
-                    select_from(select_stmt).\\
-                    filter(User.name == 'ed')
-
-        Produces SQL where both the ``user`` table as well as the
-        ``select_stmt`` construct are present as separate elements
-        in the FROM clause.  No "adaptation" of the ``user`` table
-        is applied::
-
-            SELECT "user".id AS user_id, "user".name AS user_name
-            FROM "user", (SELECT "user".id AS id, "user".name AS name
-            FROM "user"
-            WHERE "user".id = :id_1) AS anon_1
-            WHERE "user".name = :name_1
-
-        :meth:`.Query.select_entity_from` maintains an older
-        behavior of :meth:`.Query.select_from`.  In modern usage,
-        similar results can also be achieved using :func:`.aliased`::
-
-            select_stmt = select([User]).where(User.id == 7)
-            user_from_select = aliased(User, select_stmt.alias())
-
-            q = session.query(user_from_select)
-
-        :param from_obj: a :class:`.FromClause` object that will replace
-         the FROM clause of this :class:`.Query`.

-
-        .. versionadded:: 0.8
-            :meth:`.Query.select_entity_from` was added to specify

-
-        This corresponds to a parent-child or associative table relationship.  The
-        constructed class is an instance of :class:`.RelationshipProperty`.
-
-        A typical :func:`.relationship`, used in a classical mapping::
-
-           mapper(Parent, properties={
-             'children': relationship(Child)
-           })
-
-        Some arguments accepted by :func:`.relationship` optionally accept a
-        callable function, which when called produces the desired value.
-        The callable is invoked by the parent :class:`.Mapper` at "mapper
-        initialization" time, which happens only when mappers are first used, and
-        is assumed to be after all mappings have been constructed.  This can be
-        used to resolve order-of-declaration and other dependency issues, such as
-        if ``Child`` is declared below ``Parent`` in the same file::
-
-            mapper(Parent, properties={
-                "children":relationship(lambda: Child,
-                                    order_by=lambda: Child.id)
-            })
-
-        When using the :ref:`declarative_toplevel` extension, the Declarative
-        initializer allows string arguments to be passed to :func:`.relationship`.
-        These string arguments are converted into callables that evaluate
-        the string as Python code, using the Declarative
-        class-registry as a namespace.  This allows the lookup of related
-        classes to be automatic via their string name, and removes the need to
-        import related classes at all into the local module space::
-
-            from sqlalchemy.ext.declarative import declarative_base
-
-            Base = declarative_base()
-
-            class Parent(Base):
-                __tablename__ = 'parent'
-                id = Column(Integer, primary_key=True)
-                children = relationship("Child", order_by="Child.id")

-
-        :param argument:
-          a mapped class, or actual :class:`.Mapper` instance, representing the
-          target of the relationship.
-
-          :paramref:`~.relationship.argument` may also be passed as a callable function
-          which is evaluated at mapper initialization time, and may be passed as a
-          Python-evaluable string when using Declarative.

-            on relationship configuration when using Declarative.
-
-        :param secondary:
-          for a many-to-many relationship, specifies the intermediary
-          table, and is typically an instance of :class:`.Table`.
-          In less common circumstances, the argument may also be specified
-          as an :class:`.Alias` construct, or even a :class:`.Join` construct.
-
-          :paramref:`~.relationship.secondary` may
-          also be passed as a callable function which is evaluated at
-          mapper initialization time.  When using Declarative, it may also
-          be a string argument noting the name of a :class:`.Table` that is
-          present in the :class:`.MetaData` collection associated with the
-          parent-mapped :class:`.Table`.
-
-          The :paramref:`~.relationship.secondary` keyword argument is typically
-          applied in the case where the intermediary :class:`.Table` is not
-          otherwise exprssed in any direct class mapping. If the "secondary" table
-          is also explicitly mapped elsewhere
-          (e.g. as in :ref:`association_pattern`), one should consider applying
-          the :paramref:`~.relationship.viewonly` flag so that this :func:`.relationship`
-          is not used for persistence operations which may conflict with those
-          of the association object pattern.

-          not already loaded. Normally, history tracking logic for

-          This defaults to ``False``, which means the default cascade

-          When set to ``False``, the attribute managed by this relationship

-        :param distinct_target_key=None:

-          the DISTINCT keyword will be applied in those cases when the target
-          columns do not comprise the full primary key of the target table.
-          When set to ``True``, the DISTINCT keyword is applied to the innermost
-          SELECT unconditionally.
-
-          It may be desirable to set this flag to False when the DISTINCT is
-          reducing performance of the innermost subquery beyond that of what
-          duplicate innermost rows may be causing.

-
-        :param foreign_keys:
-
-          a list of columns which are to be used as "foreign key"
-          columns, or columns which refer to the value in a remote
-          column, within the context of this :func:`.relationship`
-          object's :paramref:`~.relationship.primaryjoin` condition.
-          That is, if the :paramref:`~.relationship.primaryjoin`
-          condition of this :func:`.relationship` is ``a.id ==
-          b.a_id``, and the values in ``b.a_id`` are required to be
-          present in ``a.id``, then the "foreign key" column of this
-          :func:`.relationship` is ``b.a_id``.
-
-          In normal cases, the :paramref:`~.relationship.foreign_keys`
-          parameter is **not required.** :func:`.relationship` will
-          automatically determine which columns in the
-          :paramref:`~.relationship.primaryjoin` conditition are to be
-          considered "foreign key" columns based on those
-          :class:`.Column` objects that specify :class:`.ForeignKey`,
-          or are otherwise listed as referencing columns in a
-          :class:`.ForeignKeyConstraint` construct.
-          :paramref:`~.relationship.foreign_keys` is only needed when:
-
-            1. There is more than one way to construct a join from the local
-               table to the remote table, as there are multiple foreign key
-               references present.  Setting ``foreign_keys`` will limit the
-               :func:`.relationship` to consider just those columns specified
-               here as "foreign".
-
-               .. versionchanged:: 0.8
-                    A multiple-foreign key join ambiguity can be resolved by
-                    setting the :paramref:`~.relationship.foreign_keys` parameter alone, without the
-                    need to explicitly set :paramref:`~.relationship.primaryjoin` as well.
-
-            2. The :class:`.Table` being mapped does not actually have
-               :class:`.ForeignKey` or :class:`.ForeignKeyConstraint`
-               constructs present, often because the table
-               was reflected from a database that does not support foreign key
-               reflection (MySQL MyISAM).
-
-            3. The :paramref:`~.relationship.primaryjoin` argument is used to construct a non-standard
-               join condition, which makes use of columns or expressions that do
-               not normally refer to their "parent" column, such as a join condition
-               expressed by a complex comparison using a SQL function.
-
-          The :func:`.relationship` construct will raise informative
-          error messages that suggest the use of the
-          :paramref:`~.relationship.foreign_keys` parameter when
-          presented with an ambiguous condition.   In typical cases,
-          if :func:`.relationship` doesn't raise any exceptions, the
-          :paramref:`~.relationship.foreign_keys` parameter is usually
-          not needed.
-
-          :paramref:`~.relationship.foreign_keys` may also be passed as a callable function
-          which is evaluated at mapper initialization time, and may be passed as a
-          Python-evaluable string when using Declarative.

-
-        :param innerjoin=False:
-          when ``True``, joined eager loads will use an inner join to join
-          against related tables instead of an outer join.  The purpose
-          of this option is generally one of performance, as inner joins
-          generally perform better than outer joins.
-
-          This flag can be set to ``True`` when the relationship references an
-          object via many-to-one using local foreign keys that are not nullable,
-          or when the reference is one-to-one or a collection that is guaranteed
-          to have one or at least one entry.
-
-          If the joined-eager load is chained onto an existing LEFT OUTER JOIN,
-          ``innerjoin=True`` will be bypassed and the join will continue to
-          chain as LEFT OUTER JOIN so that the results don't change.  As an alternative,
-          specify the value ``"nested"``.  This will instead nest the join
-          on the right side, e.g. using the form "a LEFT OUTER JOIN (b JOIN c)".
-
-          .. versionadded:: 0.9.4 Added ``innerjoin="nested"`` option to support
-             nesting of eager "inner" joins.

-          relationship.  The number counts how many times the same Mapper
-          shall be present in the loading condition along a particular join
-          branch.  When left at its default of ``None``, eager loaders
-          will stop chaining when they encounter a the same target mapper
-          which is already higher up in the chain.  This option applies
-          both to joined- and subquery- eager loaders.

-
-        :param lazy='select': specifies
-          how the related items should be loaded.  Default value is
-          ``select``.  Values include:
-
-          * ``select`` - items should be loaded lazily when the property is first
-            accessed, using a separate SELECT statement, or identity map
-            fetch for simple many-to-one references.
-
-          * ``immediate`` - items should be loaded as the parents are loaded,
-            using a separate SELECT statement, or identity map fetch for
-            simple many-to-one references.
-
-          * ``joined`` - items should be loaded "eagerly" in the same query as
-            that of the parent, using a JOIN or LEFT OUTER JOIN.  Whether
-            the join is "outer" or not is determined by the
-            :paramref:`~.relationship.innerjoin` parameter.
-
-          * ``subquery`` - items should be loaded "eagerly" as the parents are
-            loaded, using one additional SQL statement, which issues a JOIN to a
-            subquery of the original statement, for each collection requested.
-
-          * ``noload`` - no loading should occur at any time.  This is to
-            support "write-only" attributes, or attributes which are
-            populated in some manner specific to the application.
-
-          * ``dynamic`` - the attribute will return a pre-configured
-            :class:`.Query` object for all read
-            operations, onto which further filtering operations can be
-            applied before iterating the results.  See

-
-        :param load_on_pending=False:
-          Indicates loading behavior for transient or pending parent objects.
-
-          When set to ``True``, causes the lazy-loader to
-          issue a query for a parent object that is not persistent, meaning it has
-          never been flushed.  This may take effect for a pending object when
-          autoflush is disabled, or for a transient object that has been
-          "attached" to a :class:`.Session` but is not part of its pending
-          collection.
-
-          The :paramref:`~.relationship.load_on_pending` flag does not improve behavior
-          when the ORM is used normally - object references should be constructed
-          at the object level, not at the foreign key level, so that they
-          are present in an ordinary way before a flush proceeds.  This flag
-          is not not intended for general use.
-
-          .. seealso::
-
-              :meth:`.Session.enable_relationship_loading` - this method establishes
-              "load on pending" behavior for the whole object, and also allows
-              loading on objects that remain transient or detached.
-
-        :param order_by:
-          indicates the ordering that should be applied when loading these
-          items.  :paramref:`~.relationship.order_by` is expected to refer to one
-          of the :class:`.Column`
-          objects to which the target class is mapped, or
-          the attribute itself bound to the target class which refers
-          to the column.
-
-          :paramref:`~.relationship.order_by` may also be passed as a callable function
-          which is evaluated at mapper initialization time, and may be passed as a
-          Python-evaluable string when using Declarative.
-
-        :param passive_deletes=False:
-           Indicates loading behavior during delete operations.
-
-           A value of True indicates that unloaded child items should not
-           be loaded during a delete operation on the parent.  Normally,
-           when a parent item is deleted, all child items are loaded so
-           that they can either be marked as deleted, or have their
-           foreign key to the parent set to NULL.  Marking this flag as
-           True usually implies an ON DELETE <CASCADE|SET NULL> rule is in
-           place which will handle updating/deleting child rows on the
-           database side.
-
-           Additionally, setting the flag to the string value 'all' will
-           disable the "nulling out" of the child foreign keys, when there
-           is no delete or delete-orphan cascade enabled.  This is
-           typically used when a triggering or error raise scenario is in
-           place on the database side.  Note that the foreign key
-           attributes on in-session child objects will not be changed
-           after a flush occurs so this is a very special use-case
-           setting.
-
-           .. seealso::

-                :ref:`passive_deletes` - Introductory documentation
-                and examples.
-
-        :param passive_updates=True:
-          Indicates loading and INSERT/UPDATE/DELETE behavior when the
-          source of a foreign key value changes (i.e. an "on update"
-          cascade), which are typically the primary key columns of the
-          source row.
-
-          When True, it is assumed that ON UPDATE CASCADE is configured on
-          the foreign key in the database, and that the database will
-          handle propagation of an UPDATE from a source column to
-          dependent rows.  Note that with databases which enforce
-          referential integrity (i.e. PostgreSQL, MySQL with InnoDB tables),
-          ON UPDATE CASCADE is required for this operation.  The
-          relationship() will update the value of the attribute on related
-          items which are locally present in the session during a flush.
-
-          When False, it is assumed that the database does not enforce
-          referential integrity and will not be issuing its own CASCADE
-          operation for an update.  The relationship() will issue the
-          appropriate UPDATE statements to the database in response to the
-          change of a referenced key, and items locally present in the
-          session during a flush will also be refreshed.
-
-          This flag should probably be set to False if primary key changes
-          are expected and the database in use doesn't support CASCADE
-          (i.e. SQLite, MySQL MyISAM tables).

-              takes effect for joined-table inheritance mappings.
-
-        :param post_update:
-          this indicates that the relationship should be handled by a
-          second UPDATE statement after an INSERT or before a
-          DELETE. Currently, it also will issue an UPDATE after the
-          instance was UPDATEd as well, although this technically should
-          be improved. This flag is used to handle saving bi-directional
-          dependencies between two individual rows (i.e. each row
-          references the other), where it would otherwise be impossible to
-          INSERT or DELETE both rows fully since one row exists before the
-          other. Use this flag when a particular mapping arrangement will
-          incur two rows that are dependent on each other, such as a table
-          that has a one-to-many relationship to a set of child rows, and
-          also has a column that references a single child row within that
-          list (i.e. both tables contain a foreign key to each other). If

-          many-to-many relationship the join of the primary object to the
-          association table. By default, this value is computed based on the
-          foreign key relationships of the parent and child tables (or association
-          table).
-
-          :paramref:`~.relationship.primaryjoin` may also be passed as a callable function

-            is used to configure self-referential relationships.
-
-            :func:`.remote` - an annotation function that accomplishes the same

-          a :class:`.Query` subclass that will be used as the base of the
-          "appender query" returned by a "dynamic" relationship, that
-          is, a relationship that specifies ``lazy="dynamic"`` or was

-        :param secondaryjoin:
-          a SQL expression that will be used as the join of
-          an association table to the child object. By default, this value is
-          computed based on the foreign key relationships of the association and
-          child tables.
-
-          :paramref:`~.relationship.secondaryjoin` may also be passed as a callable function
-          which is evaluated at mapper initialization time, and may be passed as a
-          Python-evaluable string when using Declarative.

-          when True, installs a validator which will prevent objects
-          from being associated with more than one parent at a time.
-          This is used for many-to-one or many-to-many relationships that
-          should be treated either as one-to-one or one-to-many.  Its usage
-          is optional, except for :func:`.relationship` constructs which
-          are many-to-one or many-to-many and also
-          specify the ``delete-orphan`` cascade option.  The :func:`.relationship`
-          construct itself will raise an error instructing when this option
-          is required.

-
-        :param uselist:
-          a boolean that indicates if this property should be loaded as a
-          list or a scalar. In most cases, this value is determined
-          automatically by :func:`.relationship` at mapper configuration
-          time, based on the type and direction
-          of the relationship - one to many forms a list, many to one
-          forms a scalar, many to many is a list. If a scalar is desired
-          where normally a list would be present, such as a bi-directional
-          one-to-one relationship, set :paramref:`~.relationship.uselist` to False.
-
-          The :paramref:`~.relationship.uselist` flag is also available on an
-          existing :func:`.relationship` construct as a read-only attribute, which
-          can be used to determine if this :func:`.relationship` deals with
-          collections or scalar attributes::
-
-              >>> User.addresses.property.uselist
-              True

-
-              :ref:`relationships_one_to_one` - Introduction to the "one to one"
-              relationship pattern, which is typically when the
-              :paramref:`~.relationship.uselist` flag is needed.
-
-        :param viewonly=False:
-          when set to True, the relationship is used only for loading objects,
-          and not for any persistence operation.  A :func:`.relationship`
-          which specifies :paramref:`~.relationship.viewonly` can work
-          with a wider range of SQL operations within the :paramref:`~.relationship.primaryjoin`
-          condition, including operations that feature the use of
-          a variety of comparison operators as well as SQL functions such
-          as :func:`~.sql.expression.cast`.  The :paramref:`~.relationship.viewonly`
-          flag is also of general use when defining any kind of :func:`~.relationship`
-          that doesn't represent the full set of related objects, to prevent
-          modifications of the collection from resulting in persistence operations.

-    """A :class:`.Session`-level transaction.
-
-    :class:`.SessionTransaction` is a mostly behind-the-scenes object
-    not normally referenced directly by application code.   It coordinates
-    among multiple :class:`.Connection` objects, maintaining a database
-    transaction for each one individually, committing or rolling them
-    back all at once.   It also provides optional two-phase commit behavior
-    which can augment this coordination operation.
-
-    The :attr:`.Session.transaction` attribute of :class:`.Session`
-    refers to the current :class:`.SessionTransaction` object in use, if any.
-
-
-    A :class:`.SessionTransaction` is associated with a :class:`.Session`
-    in its default mode of ``autocommit=False`` immediately, associated
-    with no database connections.  As the :class:`.Session` is called upon
-    to emit SQL on behalf of various :class:`.Engine` or :class:`.Connection`
-    objects, a corresponding :class:`.Connection` and associated
-    :class:`.Transaction` is added to a collection within the
-    :class:`.SessionTransaction` object, becoming one of the
-    connection/transaction pairs maintained by the
-    :class:`.SessionTransaction`.
-
-    The lifespan of the :class:`.SessionTransaction` ends when the
-    :meth:`.Session.commit`, :meth:`.Session.rollback` or
-    :meth:`.Session.close` methods are called.  At this point, the
-    :class:`.SessionTransaction` removes its association with its parent
-    :class:`.Session`.   A :class:`.Session` that is in ``autocommit=False``
-    mode will create a new :class:`.SessionTransaction` to replace it
-    immediately, whereas a :class:`.Session` that's in ``autocommit=True``
-    mode will remain without a :class:`.SessionTransaction` until the
-    :meth:`.Session.begin` method is called.
-
-    Another detail of :class:`.SessionTransaction` behavior is that it is
-    capable of "nesting".  This means that the :meth:`.Session.begin` method
-    can be called while an existing :class:`.SessionTransaction` is already
-    present, producing a new :class:`.SessionTransaction` that temporarily
-    replaces the parent :class:`.SessionTransaction`.   When a
-    :class:`.SessionTransaction` is produced as nested, it assigns itself to
-    the :attr:`.Session.transaction` attribute.  When it is ended via
-    :meth:`.Session.commit` or :meth:`.Session.rollback`, it restores its
-    parent :class:`.SessionTransaction` back onto the
-    :attr:`.Session.transaction` attribute.  The behavior is effectively a
-    stack, where :attr:`.Session.transaction` refers to the current head of
-    the stack.
-
-    The purpose of this stack is to allow nesting of
-    :meth:`.Session.rollback` or :meth:`.Session.commit` calls in context
-    with various flavors of :meth:`.Session.begin`. This nesting behavior
-    applies to when :meth:`.Session.begin_nested` is used to emit a
-    SAVEPOINT transaction, and is also used to produce a so-called
-    "subtransaction" which allows a block of code to use a
-    begin/rollback/commit sequence regardless of whether or not its enclosing
-    code block has begun a transaction.  The :meth:`.flush` method, whether
-    called explicitly or via autoflush, is the primary consumer of the
-    "subtransaction" feature, in that it wishes to guarantee that it works
-    within in a transaction block regardless of whether or not the
-    :class:`.Session` is in transactional mode when the method is called.

-        See also the :class:`.sessionmaker` function which is used to

-        set of arguments.
-
-        :param autocommit:
-
-          .. warning::
-
-             The autocommit flag is **not for general use**, and if it is used,
-             queries should only be invoked within the span of a
-             :meth:`.Session.begin` / :meth:`.Session.commit` pair.   Executing
-             queries outside of a demarcated transaction is a legacy mode
-             of usage, and can in some cases lead to concurrent connection
-             checkouts.
-
-          Defaults to ``False``. When ``True``, the
-          :class:`.Session` does not keep a persistent transaction running, and
-          will acquire connections from the engine on an as-needed basis,
-          returning them immediately after their use. Flushes will begin and
-          commit (or possibly rollback) their own transaction if no
-          transaction is present. When using this mode, the
-          :meth:`.Session.begin` method is used to explicitly start
-          transactions.
-
-          .. seealso::
-
-            :ref:`session_autocommit`
-
-        :param autoflush: When ``True``, all query operations will issue a
-           ``flush()`` call to this ``Session`` before proceeding. This is a
-           convenience feature so that ``flush()`` need not be called
-           repeatedly in order for database queries to retrieve results. It's
-           typical that ``autoflush`` is used in conjunction with
-           ``autocommit=False``. In this scenario, explicit calls to
-           ``flush()`` are rarely needed; you usually only need to call
-           ``commit()`` (which flushes) to finalize changes.
-
-        :param bind: An optional ``Engine`` or ``Connection`` to which this
-           ``Session`` should be bound. When specified, all SQL operations
-           performed by this session will execute via this connectable.
-
-        :param binds: An optional dictionary which contains more granular
-           "bind" information than the ``bind`` parameter provides. This
-           dictionary can map individual ``Table`` instances as well as
-           ``Mapper`` instances to individual ``Engine`` or ``Connection``
-           objects. Operations which proceed relative to a particular
-           ``Mapper`` will consult this dictionary for the direct ``Mapper``
-           instance as well as the mapper's ``mapped_table`` attribute in
-           order to locate an connectable to use. The full resolution is
-           described in the ``get_bind()`` method of ``Session``.
-           Usage looks like::
-
-            Session = sessionmaker(binds={
-                SomeMappedClass: create_engine('postgresql://engine1'),
-                somemapper: create_engine('postgresql://engine2'),
-                some_table: create_engine('postgresql://engine3'),
-                })
-
-          Also see the :meth:`.Session.bind_mapper`
-          and :meth:`.Session.bind_table` methods.
-
-        :param \class_: Specify an alternate class other than
-           ``sqlalchemy.orm.session.Session`` which should be used by the
-           returned class. This is the only argument that is local to the
-           ``sessionmaker()`` function, and is not sent directly to the
-           constructor for ``Session``.
-
-        :param _enable_transaction_accounting:  Defaults to ``True``.  A
-           legacy-only flag which when ``False`` disables *all* 0.5-style
-           object accounting on transaction boundaries, including auto-expiry
-           of instances on rollback and commit, maintenance of the "new" and
-           "deleted" lists upon rollback, and autoflush of pending changes upon
-           begin(), all of which are interdependent.
-
-        :param expire_on_commit:  Defaults to ``True``. When ``True``, all
-           instances will be fully expired after each ``commit()``, so that
-           all attribute/object access subsequent to a completed transaction
-           will load from the most recent database state.
-
-        :param extension: An optional
-           :class:`~.SessionExtension` instance, or a list
-           of such instances, which will receive pre- and post- commit and
-           flush events, as well as a post-rollback event. **Deprecated.**
-           Please see :class:`.SessionEvents`.
-
-        :param info: optional dictionary of arbitrary data to be associated
-           with this :class:`.Session`.  Is available via the :attr:`.Session.info`
-           attribute.  Note the dictionary is copied at construction time so
-           that modifications to the per-:class:`.Session` dictionary will be local
-           to that :class:`.Session`.
-
-           .. versionadded:: 0.9.0
-

-        :func:`~.expression.text` construct.  That is, the following usage::
-
-            result = session.execute(
-                        "SELECT * FROM user WHERE id=:param",

-            result = session.execute(

-                    )
-
-        The second positional argument to :meth:`.Session.execute` is an
-        optional parameter set.  Similar to that of
-        :meth:`.Connection.execute`, whether this is passed as a single
-        dictionary, or a list of dictionaries, determines whether the DBAPI
-        cursor's ``execute()`` or ``executemany()`` is used to execute the
-        statement.   An INSERT construct may be invoked for a single row::
-
-            result = session.execute(users.insert(), {"id": 7, "name": "somename"})
-
-        or for multiple rows::
-
-            result = session.execute(users.insert(), [
-                                    {"id": 7, "name": "somename7"},

-                                    {"id": 9, "name": "somename9"}
-                                ])
-
-        The statement is executed within the current transactional context of
-        this :class:`.Session`.   The :class:`.Connection` which is used
-        to execute the statement can also be acquired directly by
-        calling the :meth:`.Session.connection` method.  Both methods use
-        a rule-based resolution scheme in order to determine the
-        :class:`.Connection`, which in the average case is derived directly
-        from the "bind" of the :class:`.Session` itself, and in other cases
-        can be based on the :func:`.mapper`
-        and :class:`.Table` objects passed to the method; see the documentation
-        for :meth:`.Session.get_bind` for a full description of this scheme.
-
-        The :meth:`.Session.execute` method does *not* invoke autoflush.
-
-        The :class:`.ResultProxy` returned by the :meth:`.Session.execute`
-        method is returned with the "close_with_result" flag set to true;
-        the significance of this flag is that if this :class:`.Session` is
-        autocommitting and does not have a transaction-dedicated
-        :class:`.Connection` available, a temporary :class:`.Connection` is
-        established for the statement execution, which is closed (meaning,
-        returned to the connection pool) when the :class:`.ResultProxy` has
-        consumed all available data. This applies *only* when the
-        :class:`.Session` is configured with autocommit=True and no
-        transaction has been started.

-            "executemany" will be invoked.  The keys in each dictionary
-            must correspond to parameter names present in the statement.
-

-         any existing related objects or collections that might not
-         be loaded.  The resulting objects from ``load=False`` are always
-         produced as "clean", so it is only appropriate that the given objects

-            use cases and is not recommended for general use.

-        Accesses of attributes mapped with :func:`.relationship`
-        will attempt to load a value from the database using this
-        :class:`.Session` as the source of connectivity.  The values
-        will be loaded based on foreign key values present on this
-        object - it follows that this functionality
-        generally only works for many-to-one-relationships.
-
-        The object will be attached to this session, but will
-        **not** participate in any persistence operations; its state
-        for almost all purposes will remain either "transient" or
-        "detached", except for the case of relationship loading.
-
-        Also note that backrefs will often not work as expected.
-        Altering a relationship-bound attribute on the target object
-        may not fire off a backref event, if the effective value
-        is what was already loaded from a foreign-key-holding value.
-
-        The :meth:`.Session.enable_relationship_loading` method is
-        similar to the ``load_on_pending`` flag on :func:`.relationship`.   Unlike
-        that flag, :meth:`.Session.enable_relationship_loading` allows
-        an object to remain transient while still being able to load
-        related items.
-
-        To make a transient object associated with a :class:`.Session`
-        via :meth:`.Session.enable_relationship_loading` pending, add
-        it to the :class:`.Session` using :meth:`.Session.add` normally.
-
-        :meth:`.Session.enable_relationship_loading` does not improve
-        behavior when the ORM is used normally - object references should be
-        constructed at the object level, not at the foreign key level, so
-        that they are present in an ordinary way before flush()

-        This method retrieves the history for each instrumented

-        value to its previously committed value, if any.
-
-        It is in effect a more expensive and accurate
-        version of checking for the given instance in the
-        :attr:`.Session.dirty` collection; a full test for
-        each attribute's net "dirty" status is performed.
-
-        E.g.::
-
-            return session.is_modified(someobject)
-
-        .. versionchanged:: 0.8
-            When using SQLAlchemy 0.7 and earlier, the ``passive``
-            flag should **always** be explicitly set to ``True``,
-            else SQL loads/autoflushes may proceed which can affect
-            the modified state itself:
-            ``session.is_modified(someobject, passive=True)``\ .
-            In 0.8 and above, the behavior is corrected and
-            this flag is ignored.
-
-        A few caveats to this method apply:
-
-        * Instances present in the :attr:`.Session.dirty` collection may report
-          ``False`` when tested with this method.  This is because
-          the object may have received change events via attribute
-          mutation, thus placing it in :attr:`.Session.dirty`,
-          but ultimately the state is the same as that loaded from
-          the database, resulting in no net change here.
-        * Scalar attributes may not have recorded the previously set
-          value when a new value was applied, if the attribute was not loaded,
-          or was expired, at the time the new value was received - in these
-          cases, the attribute is assumed to have a change, even if there is
-          ultimately no net change against its database value. SQLAlchemy in
-          most cases does not need the "old" value when a set event occurs, so
-          it skips the expense of a SQL call if the old value isn't present,
-          based on the assumption that an UPDATE of the scalar value is
-          usually needed, and in those few cases where it isn't, is less
-          expensive on average than issuing a defensive SELECT.
-
-          The "old" value is fetched unconditionally upon set only if the
-          attribute container has the ``active_history`` flag set to ``True``.
-          This flag is set typically for primary key attributes and scalar
-          object references that are not a simple many-to-one.  To set this
-          flag for any arbitrary mapped column, use the ``active_history``
-          argument with :func:`.column_property`.
-
-        :param instance: mapped instance to be tested for pending changes.
-        :param include_collections: Indicates if multivalued collections
-         should be included in the operation.  Setting this to ``False`` is a
-         way to detect only local-column based properties (i.e. scalar columns
-         or many-to-one foreign keys) that would result in an UPDATE for this
-         instance upon flush.
-        :param passive:
-         .. versionchanged:: 0.8
-             Ignored for backwards compatibility.

-        is not in "partial rollback" state.
-
-        The :class:`.Session` in its default mode of ``autocommit=False``
-        is essentially always in "transaction mode", in that a
-        :class:`.SessionTransaction` is associated with it as soon as
-        it is instantiated.  This :class:`.SessionTransaction` is immediately
-        replaced with a new one as soon as it is ended, due to a rollback,
-        commit, or close operation.
-
-        "Transaction mode" does *not* indicate whether
-        or not actual database connection resources are in use;  the
-        :class:`.SessionTransaction` object coordinates among zero or more
-        actual database transactions, and starts out with none, accumulating
-        individual DBAPI connections as different data sources are used
-        within its scope.   The best way to track when a particular
-        :class:`.Session` has actually begun to use DBAPI resources is to
-        implement a listener using the :meth:`.SessionEvents.after_begin`
-        method, which will deliver both the :class:`.Session` as well as the
-        target :class:`.Connection` to a user-defined event listener.
-
-        The "partial rollback" state refers to when an "inner" transaction,
-        typically used during a flush, encounters an error and emits a
-        rollback of the DBAPI connection.  At this point, the
-        :class:`.Session` is in "partial rollback" and awaits for the user to
-        call :meth:`.Session.rollback`, in order to close out the
-        transaction stack.  It is in this "partial rollback" period that the
-        :attr:`.is_active` flag returns False.  After the call to
-        :meth:`.Session.rollback`, the :class:`.SessionTransaction` is replaced
-        with a new one and :attr:`.is_active` returns ``True`` again.
-
-        When a :class:`.Session` is used in ``autocommit=True`` mode, the
-        :class:`.SessionTransaction` is only instantiated within the scope
-        of a flush call, or when :meth:`.Session.begin` is called.  So
-        :attr:`.is_active` will always be ``False`` outside of a flush or
-        :meth:`.Session.begin` block in this mode, and will be ``True``
-        within the :meth:`.Session.begin` block as long as it doesn't enter
-        "partial rollback" state.
-
-        From all the above, it follows that the only purpose to this flag is
-        for application frameworks that wish to detect is a "rollback" is
-        necessary within a generic error handling routine, for
-        :class:`.Session` objects that would otherwise be in
-        "partial rollback" mode.  In a typical integration case, this is also
-        not necessary as it is standard practice to emit
-        :meth:`.Session.rollback` unconditionally within the outermost
-        exception catch.
-
-        To track the transactional state of a :class:`.Session` fully,
-        use event listeners, primarily the :meth:`.SessionEvents.after_begin`,
-        :meth:`.SessionEvents.after_commit`,
-        :meth:`.SessionEvents.after_rollback` and related events.

-class Load(Generative, MapperOption):
-    """Represents loader options which modify the state of a
-    :class:`.Query` in order to affect how various mapped attributes are loaded.
-
-    .. versionadded:: 0.9.0 The :meth:`.Load` system is a new foundation for
-       the existing system of loader options, including options such as
-       :func:`.orm.joinedload`, :func:`.orm.defer`, and others.   In particular,
-       it introduces a new method-chained system that replaces the need for
-       dot-separated paths as well as "_all()" options such as :func:`.orm.joinedload_all`.
-
-    A :class:`.Load` object can be used directly or indirectly.  To use one
-    directly, instantiate given the parent class.  This style of usage is
-    useful when dealing with a :class:`.Query` that has multiple entities,
-    or when producing a loader option that can be applied generically to
-    any style of query::
-
-        myopt = Load(MyClass).joinedload("widgets")
-
-    The above ``myopt`` can now be used with :meth:`.Query.options`::
-
-        session.query(MyClass).options(myopt)
-
-    The :class:`.Load` construct is invoked indirectly whenever one makes use
-    of the various loader options that are present in ``sqlalchemy.orm``, including
-    options such as :func:`.orm.joinedload`, :func:`.orm.defer`, :func:`.orm.subqueryload`,
-    and all the rest.  These constructs produce an "anonymous" form of the
-    :class:`.Load` object which tracks attributes and options, but is not linked
-    to a parent class until it is associated with a parent :class:`.Query`::
-
-        # produce "unbound" Load object
-        myopt = joinedload("widgets")
-
-        # when applied using options(), the option is "bound" to the
-        # class observed in the given query, e.g. MyClass
-        session.query(MyClass).options(myopt)
-
-    Whether the direct or indirect style is used, the :class:`.Load` object
-    returned now represents a specific "path" along the entities of a :class:`.Query`.
-    This path can be traversed using a standard method-chaining approach.
-    Supposing a class hierarchy such as ``User``, ``User.addresses -> Address``,
-    ``User.orders -> Order`` and ``Order.items -> Item``, we can specify a variety
-    of loader options along each element in the "path"::
-
-        session.query(User).options(
-                    joinedload("addresses"),
-                    subqueryload("orders").joinedload("items")
-                )
-
-    Where above, the ``addresses`` collection will be joined-loaded, the
-    ``orders`` collection will be subquery-loaded, and within that subquery load
-    the ``items`` collection will be joined-loaded.

-
-      This form receives a mapped class and a primary key scalar or

-
-      E.g.::

-      :param ident: primary key, may be a scalar or tuple argument.
-
-
-    * ``identity_key(instance=instance)``
-
-      This form will produce the identity key for a given instance.  The
-      instance need not be persistent, only that its primary key attributes
-      are populated (else the key will contain ``None`` for those missing

-    The :func:`.aliased` function is used to create an ad-hoc mapping

-    is generated from the normally mapped selectable (typically a
-    :class:`.Table`) using the :meth:`.FromClause.alias` method.
-    However, :func:`.aliased` can also be used to link the class to
-    a new :func:`.select` statement.   Also, the :func:`.with_polymorphic`
-    function is a variant of :func:`.aliased` that is intended to specify
-    a so-called "polymorphic selectable", that corresponds to the union
-    of several joined-inheritance subclasses at once.
-
-    For convenience, the :func:`.aliased` function also accepts plain
-    :class:`.FromClause` constructs, such as a :class:`.Table` or
-    :func:`.select` construct.   In those cases, the :meth:`.FromClause.alias`
-    method is called on the object and the new :class:`.Alias` object
-    returned.  The returned :class:`.Alias` is not ORM-mapped in this case.
-
-    :param element: element to be aliased.  Is normally a mapped class,
-     but for convenience can also be a :class:`.FromClause` element.
-
-    :param alias: Optional selectable unit to map the element to.  This should
-     normally be a :class:`.Alias` object corresponding to the :class:`.Table`
-     to which the class is mapped, or to a :func:`.select` construct that
-     is compatible with the mapping.   By default, a simple anonymous
-     alias of the mapped table is generated.
-
-    :param name: optional string name to use for the alias, if not specified
-     by the ``alias`` parameter.  The name, among other things, forms the
-     attribute name that will be accessible via tuples returned by a
-     :class:`.Query` object.
-
-    :param flat: Boolean, will be passed through to the :meth:`.FromClause.alias`
-     call so that aliases of :class:`.Join` objects don't include an enclosing
-     SELECT.  This can lead to more efficient queries in many circumstances.
-     A JOIN against a nested JOIN will be rewritten as a JOIN against an aliased
-     SELECT subquery on backends that don't support this syntax.

-          * ``"rollback"`` - call rollback() on the connection,
-            to release locks and transaction resources.
-            This is the default value.  The vast majority
-            of use cases should leave this value set.
-          * ``True`` - same as 'rollback', this is here for
-            backwards compatibility.
-          * ``"commit"`` - call commit() on the connection,
-            to release locks and transaction resources.
-            A commit here may be desirable for databases that
-            cache query plans if a commit is emitted,
-            such as Microsoft SQL Server.  However, this
-            value is more dangerous than 'rollback' because
-            any data changes present on the transaction
-            are committed unconditionally.
-          * ``None`` - don't do anything on the connection.
-            This setting should only be made on a database
-            that has no transaction support at all,
-            namely MySQL MyISAM.   By not doing anything,
-            performance can be improved.   This
-            setting should **never be selected** for a
-            database that supports transactions,
-            as it will lead to deadlocks and stale
-            state.
-          * ``False`` - same as None, this is here for
-            backwards compatibility.

-                text += " DEFAULT " + default
-

-                            for const in column.constraints)
-            return text
-
-    The above construct can be applied to a :class:`.Table` as follows::
-
-        from sqlalchemy import Table, Metadata, Column, Integer, String
-        from sqlalchemy import schema
-
-        metadata = MetaData()
-
-        table = Table('mytable', MetaData(),
-                Column('x', Integer, info={"special":True}, primary_key=True),
-                Column('y', String(50)),
-                Column('z', String(20), info={"special":True})
-            )
-
-        metadata.create_all(conn)
-
-    Above, the directives we've added to the :attr:`.Column.info` collection
-    will be detected by our custom compilation scheme::
-
-        CREATE TABLE mytable (
-                x SPECIAL DIRECTIVE INTEGER NOT NULL,
-                y VARCHAR(50),
-                z SPECIAL DIRECTIVE VARCHAR(20),
-            PRIMARY KEY (x)
-        )
-
-    The :class:`.CreateColumn` construct can also be used to skip certain
-    columns when producing a ``CREATE TABLE``.  This is accomplished by
-    creating a compilation rule that conditionally returns ``None``.
-    This is essentially how to produce the same effect as using the
-    ``system=True`` argument on :class:`.Column`, which marks a column
-    as an implicitly-present "system" column.
-
-    For example, suppose we wish to produce a :class:`.Table` which skips
-    rendering of the Postgresql ``xmin`` column against the Postgresql backend,
-    but on other backends does render it, in anticipation of a triggered rule.
-    A conditional compilation rule could skip this name only on Postgresql::
-
-        from sqlalchemy.schema import CreateColumn
-
-        @compiles(CreateColumn, "postgresql")
-        def skip_xmin(element, compiler, **kw):
-            if element.element.name == 'xmin':
-                return None
-            else:
-                return compiler.visit_create_column(element, **kw)
-
-
-        my_table = Table('mytable', metadata,
-                    Column('id', Integer, primary_key=True),
-                    Column('xmin', Integer)
-                )
-
-    Above, a :class:`.CreateTable` construct will generate a ``CREATE TABLE``
-    which only includes the ``id`` column in the string; the ``xmin`` column
-    will be omitted, but only against the Postgresql backend.
-
-    .. versionadded:: 0.8.3 The :class:`.CreateColumn` construct supports
-       skipping of columns by returning ``None`` from a custom compilation rule.
-
-    .. versionadded:: 0.8 The :class:`.CreateColumn` construct was added
-       to support custom column creation styles.

-         The :class:`.Insert` construct also supports multiply-rendered VALUES
-         construct, for those backends which support this SQL syntax
-         (SQLite, Postgresql, MySQL).  This mode is indicated by passing a list
-         of one or more dictionaries/tuples::
-
-            users.insert().values([
-                                {"name": "some name"},
-                                {"name": "some other name"},
-                                {"name": "yet another name"},
-                            ])
-
-         In the case of an :class:`.Update`
-         construct, only the single dictionary/tuple form is accepted,
-         else an exception is raised.  It is also an exception case to
-         attempt to mix the single-/multiple- value styles together,
-         either through multiple :meth:`.ValuesBase.values` calls
-         or by sending a list + kwargs at the same time.
-
-         .. note::
-
-             Passing a multiple values list is *not* the same
-             as passing a multiple values list to the :meth:`.Connection.execute`
-             method.  Passing a list of parameter sets to :meth:`.ValuesBase.values`
-             produces a construct of this form::
-
-                INSERT INTO table (col1, col2, col3) VALUES
-                                (col1_0, col2_0, col3_0),
-                                (col1_1, col2_1, col3_1),
-                                ...
-
-             whereas a multiple list passed to :meth:`.Connection.execute`
-             has the effect of using the DBAPI
-             `executemany() <http://www.python.org/dev/peps/pep-0249/#id18>`_
-             method, which provides a high-performance system of invoking
-             a single-row INSERT statement many times against a series
-             of parameter sets.   The "executemany" style is supported by
-             all database backends, as it does not depend on a special SQL
-             syntax.

-
-            result = connection.execute(stmt)
-
-            server_created_at = result.returned_defaults['created_at']
-
-        When used against a backend that supports RETURNING, all column
-        values generated by SQL expression or server-side-default will be added
-        to any existing RETURNING clause, provided that
-        :meth:`.UpdateBase.returning` is not used simultaneously.   The column values
-        will then be available on the result using the
-        :attr:`.ResultProxy.returned_defaults` accessor as a
-        dictionary, referring to values keyed to the :class:`.Column` object
-        as well as its ``.key``.
-
-        This method differs from :meth:`.UpdateBase.returning` in these ways:
-
-        1. :meth:`.ValuesBase.return_defaults` is only intended for use with
-           an INSERT or an UPDATE statement that matches exactly one row.
-           While the RETURNING construct in the general sense supports multiple
-           rows for a multi-row UPDATE or DELETE statement, or for special
-           cases of INSERT that return multiple rows (e.g. INSERT from SELECT,
-           multi-valued VALUES clause), :meth:`.ValuesBase.return_defaults`
-           is intended only
-           for an "ORM-style" single-row INSERT/UPDATE statement.  The row
-           returned by the statement is also consumed implcitly when
-           :meth:`.ValuesBase.return_defaults` is used.  By contrast,
-           :meth:`.UpdateBase.returning` leaves the RETURNING result-set intact
-           with a collection of any number of rows.
-
-        2. It is compatible with the existing logic to fetch auto-generated
-           primary key values, also known as "implicit returning".  Backends that
-           support RETURNING will automatically make use of RETURNING in order
-           to fetch the value of newly generated primary keys; while the
-           :meth:`.UpdateBase.returning` method circumvents this behavior,
-           :meth:`.ValuesBase.return_defaults` leaves it intact.
-
-        3. It can be called against any backend.  Backends that don't support
-           RETURNING will skip the usage of the feature, rather than raising
-           an exception.  The return value of :attr:`.ResultProxy.returned_defaults`
-           will be ``None``
-
-        :meth:`.ValuesBase.return_defaults` is used by the ORM to provide
-        an efficient implementation for the ``eager_defaults`` feature of
-        :func:`.mapper`.

-class ColumnElement(ClauseElement, operators.ColumnOperators):
-    """Represent a column-oriented SQL expression suitable for usage in the
-    "columns" clause, WHERE clause etc. of a statement.
-
-    While the most familiar kind of :class:`.ColumnElement` is the
-    :class:`.Column` object, :class:`.ColumnElement` serves as the basis
-    for any unit that may be present in a SQL expression, including
-    the expressions themselves, SQL functions, bound parameters,
-    literal expressions, keywords such as ``NULL``, etc.
-    :class:`.ColumnElement` is the ultimate base class for all such elements.
-
-    A wide variety of SQLAlchemy Core functions work at the SQL expression level,
-    and are intended to accept instances of :class:`.ColumnElement` as arguments.
-    These functions will typically document that they accept a "SQL expression"
-    as an argument.  What this means in terms of SQLAlchemy usually refers
-    to an input which is either already in the form of a :class:`.ColumnElement`
-    object, or a value which can be **coerced** into one.   The coercion
-    rules followed by most, but not all, SQLAlchemy Core functions with regards
-    to SQL expressions are as follows:
-
-        * a literal Python value, such as a string, integer or floating
-          point value, boolean, datetime, ``Decimal`` object, or virtually
-          any other Python object, will be coerced into a "literal bound value".
-          This generally means that a :func:`.bindparam` will be produced
-          featuring the given value embedded into the construct; the resulting
-          :class:`.BindParameter` object is an instance of :class:`.ColumnElement`.
-          The Python value will ultimately be sent to the DBAPI at execution time as a
-          paramterized argument to the ``execute()`` or ``executemany()`` methods,
-          after SQLAlchemy type-specific converters (e.g. those provided by
-          any associated :class:`.TypeEngine` objects) are applied to the value.
-
-        * any special object value, typically ORM-level constructs, which feature
-          a method called ``__clause_element__()``.   The Core expression system
-          looks for this method when an object of otherwise unknown type is passed
-          to a function that is looking to coerce the argument into a :class:`.ColumnElement`
-          expression.  The ``__clause_element__()`` method, if present, should
-          return a :class:`.ColumnElement` instance.  The primary use of
-          ``__clause_element__()`` within SQLAlchemy is that of class-bound attributes
-          on ORM-mapped classes; a ``User`` class which contains a mapped attribute
-          named ``.name`` will have a method ``User.name.__clause_element__()``
-          which when invoked returns the :class:`.Column` called ``name`` associated
-          with the mapped table.
-
-        * The Python ``None`` value is typically interpreted as ``NULL``, which
-          in SQLAlchemy Core produces an instance of :func:`.null`.
-
-    A :class:`.ColumnElement` provides the ability to generate new
-    :class:`.ColumnElement`
-    objects using Python expressions.  This means that Python operators
-    such as ``==``, ``!=`` and ``<`` are overloaded to mimic SQL operations,
-    and allow the instantiation of further :class:`.ColumnElement` instances
-    which are composed from other, more fundamental :class:`.ColumnElement`
-    objects.  For example, two :class:`.ColumnClause` objects can be added
-    together with the addition operator ``+`` to produce
-    a :class:`.BinaryExpression`.
-    Both :class:`.ColumnClause` and :class:`.BinaryExpression` are subclasses
-    of :class:`.ColumnElement`::
-
-        >>> from sqlalchemy.sql import column
-        >>> column('a') + column('b')
-        <sqlalchemy.sql.expression.BinaryExpression object at 0x101029dd0>
-        >>> print column('a') + column('b')
-        a + b

-        "placeholder" value in a SQL expression, the value of which is supplied
-        at the point at which the statement in executed against a database
-        connection.
-
-        In SQLAlchemy, the :func:`.bindparam` construct has
-        the ability to carry along the actual value that will be ultimately
-        used at expression time.  In this way, it serves not just as
-        a "placeholder" for eventual population, but also as a means of
-        representing so-called "unsafe" values which should not be rendered
-        directly in a SQL statement, but rather should be passed along
-        to the :term:`DBAPI` as values which need to be correctly escaped
-        and potentially handled for type-safety.
-
-        When using :func:`.bindparam` explicitly, the use case is typically
-        one of traditional deferment of parameters; the :func:`.bindparam`
-        construct accepts a name which can then be referred to at execution
-        time::
-
-            from sqlalchemy import bindparam
-
-            stmt = select([users_table]).\\
-                        where(users_table.c.name == bindparam('username'))
-
-        The above statement, when rendered, will produce SQL similar to::
-
-            SELECT id, name FROM user WHERE name = :username
-
-        In order to populate the value of ``:username`` above, the value
-        would typically be applied at execution time to a method
-        like :meth:`.Connection.execute`::
-
-            result = connection.execute(stmt, username='wendy')
-
-        Explicit use of :func:`.bindparam` is also common when producing
-        UPDATE or DELETE statements that are to be invoked multiple times,
-        where the WHERE criterion of the statement is to change on each
-        invocation, such as::
-
-            stmt = users_table.update().\\
-                            where(user_table.c.name == bindparam('username')).\\
-                            values(fullname=bindparam('fullname'))
-
-            connection.execute(stmt, [
-                                {"username": "wendy", "fullname": "Wendy Smith"},
-                                {"username": "jack", "fullname": "Jack Jones"},
-                        ])
-
-        SQLAlchemy's Core expression system makes wide use of :func:`.bindparam`
-        in an implicit sense.   It is typical that Python literal values passed to
-        virtually all SQL expression functions are coerced into fixed
-        :func:`.bindparam` constructs.  For example, given a comparison operation
-        such as::
-
-            expr = users_table.c.name == 'Wendy'
-
-        The above expression will produce a :class:`.BinaryExpression`
-        contruct, where the left side is the :class:`.Column` object
-        representing the ``name`` column, and the right side is a :class:`.BindParameter`
-        representing the literal value::
-
-            print(repr(expr.right))
-            BindParameter('%(4327771088 name)s', 'Wendy', type_=String())
-
-        The expression above will render SQL such as::
-
-            user.name = :name_1
-
-        Where the ``:name_1`` parameter name is an anonymous name.  The
-        actual string ``Wendy`` is not in the rendered string, but is carried
-        along where it is later used within statement execution.  If we
-        invoke a statement like the following::
-
-            stmt = select([users_table]).where(users_table.c.name == 'Wendy')
-            result = connection.execute(stmt)
-
-        We would see SQL logging output as::
-
-            SELECT "user".id, "user".name
-            FROM "user"
-            WHERE "user".name = %(name_1)s
-            {'name_1': 'Wendy'}
-
-        Above, we see that ``Wendy`` is passed as a parameter to the database,
-        while the placeholder ``:name_1`` is rendered in the appropriate form
-        for the target database, in this case the Postgresql database.
-
-        Similarly, :func:`.bindparam` is invoked automatically
-        when working with :term:`CRUD` statements as far as the "VALUES"
-        portion is concerned.   The :func:`.insert` construct produces an
-        ``INSERT`` expression which will, at statement execution time, generate
-        bound placeholders based on the arguments passed, as in::
-
-            stmt = users_table.insert()
-            result = connection.execute(stmt, name='Wendy')
-
-        The above will produce SQL output as::
-
-            INSERT INTO "user" (name) VALUES (%(name)s)
-            {'name': 'Wendy'}
-
-        The :class:`.Insert` construct, at compilation/execution time,
-        rendered a single :func:`.bindparam` mirroring the column
-        name ``name`` as a result of the single ``name`` parameter
-        we passed to the :meth:`.Connection.execute` method.
-
-        :param key:
-          the key (e.g. the name) for this bind param.
-          Will be used in the generated
-          SQL statement for dialects that use named parameters.  This
-          value may be modified when part of a compilation operation,
-          if other :class:`BindParameter` objects exist with the same
-          key, or if its length is too long and truncation is
-          required.
-
-        :param value:
-          Initial value for this bind param.  Will be used at statement
-          execution time as the value for this parameter passed to the
-          DBAPI, if no other value is indicated to the statement execution
-          method for this particular parameter name.  Defaults to ``None``.
-
-        :param callable\_:
-          A callable function that takes the place of "value".  The function
-          will be called at statement execution time to determine the
-          ultimate value.   Used for scenarios where the actual bind
-          value cannot be determined at the point at which the clause
-          construct is created, but embedded bind values are still desirable.
-
-        :param type\_:
-          A :class:`.TypeEngine` class or instance representing an optional
-          datatype for this :func:`.bindparam`.  If not passed, a type
-          may be determined automatically for the bind, based on the given
-          value; for example, trivial Python types such as ``str``,
-          ``int``, ``bool``
-          may result in the :class:`.String`, :class:`.Integer` or
-          :class:`.Boolean` types being autoamtically selected.
-
-          The type of a :func:`.bindparam` is significant especially in that
-          the type will apply pre-processing to the value before it is
-          passed to the database.  For example, a :func:`.bindparam` which
-          refers to a datetime value, and is specified as holding the
-          :class:`.DateTime` type, may apply conversion needed to the
-          value (such as stringification on SQLite) before passing the value
-          to the database.
-
-        :param unique:
-          if True, the key name of this :class:`.BindParameter` will be
-          modified if another :class:`.BindParameter` of the same name
-          already has been located within the containing
-          expression.  This flag is used generally by the internals
-          when producing so-called "anonymous" bound expressions, it
-          isn't generally applicable to explicitly-named :func:`.bindparam`
-          constructs.
-
-        :param required:
-          If ``True``, a value is required at execution time.  If not passed,
-          it defaults to ``True`` if neither :paramref:`.bindparam.value`
-          or :paramref:`.bindparam.callable` were passed.  If either of these
-          parameters are present, then :paramref:`.bindparam.required` defaults
-          to ``False``.
-
-          .. versionchanged:: 0.8 If the ``required`` flag is not specified,
-             it will be set automatically to ``True`` or ``False`` depending
-             on whether or not the ``value`` or ``callable`` parameters
-             were specified.
-
-        :param quote:
-          True if this parameter name requires quoting and is not
-          currently known as a SQLAlchemy reserved word; this currently
-          only applies to the Oracle backend, where bound names must
-          sometimes be quoted.
-
-        :param isoutparam:
-          if True, the parameter should be treated like a stored procedure
-          "OUT" parameter.  This applies to backends such as Oracle which
-          support OUT parameters.

-
-            t = text("SELECT * FROM users")
-            result = connection.execute(t)
-
-        The advantages :func:`.text` provides over a plain string are
-        backend-neutral support for bind parameters, per-statement
-        execution options, as well as
-        bind parameter and result-column typing behavior, allowing
-        SQLAlchemy type constructs to play a role when executing
-        a statement that is specified literally.  The construct can also
-        be provided with a ``.c`` collection of column elements, allowing
-        it to be embedded in other SQL expression constructs as a subquery.
-
-        Bind parameters are specified by name, using the format ``:name``.
-        E.g.::
-
-            t = text("SELECT * FROM users WHERE id=:user_id")
-            result = connection.execute(t, user_id=12)
-
-        For SQL statements where a colon is required verbatim, as within
-        an inline string, use a backslash to escape::
-
-            t = text("SELECT * FROM users WHERE name='\\:username'")
-
-        The :class:`.TextClause` construct includes methods which can
-        provide information about the bound parameters as well as the column
-        values which would be returned from the textual statement, assuming
-        it's an executable SELECT type of statement.  The :meth:`.TextClause.bindparams`
-        method is used to provide bound parameter detail, and
-        :meth:`.TextClause.columns` method allows specification of
-        return columns including names and types::
-
-            t = text("SELECT * FROM users WHERE id=:user_id").\\
-                    bindparams(user_id=7).\\
-                    columns(id=Integer, name=String)
-
-            for id, name in connection.execute(t):
-                print(id, name)
-
-        The :func:`.text` construct is used internally in cases when
-        a literal string is specified for part of a larger query, such as
-        when a string is specified to the :meth:`.Select.where` method of
-        :class:`.Select`.  In those cases, the same
-        bind parameter syntax is applied::
-
-            s = select([users.c.id, users.c.name]).where("id=:user_id")
-            result = connection.execute(s, user_id=12)
-
-        Using :func:`.text` explicitly usually implies the construction
-        of a full, standalone statement.   As such, SQLAlchemy refers
-        to it as an :class:`.Executable` object, and it supports
-        the :meth:`Executable.execution_options` method.  For example,
-        a :func:`.text` construct that should be subject to "autocommit"
-        can be set explicitly so using the :paramref:`.Connection.execution_options.autocommit`
-        option::
-
-            t = text("EXEC my_procedural_thing()").\\
-                    execution_options(autocommit=True)
-
-        Note that SQLAlchemy's usual "autocommit" behavior applies to
-        :func:`.text` constructs implicitly - that is, statements which begin
-        with a phrase such as ``INSERT``, ``UPDATE``, ``DELETE``,
-        or a variety of other phrases specific to certain backends, will
-        be eligible for autocommit if no transaction is in progress.
-
-        :param text:
-          the text of the SQL statement to be created.  use ``:<param>``
-          to specify bind parameters; they will be compiled to their
-          engine-specific format.
-
-        :param autocommit:
-          Deprecated.  Use .execution_options(autocommit=<True|False>)

-
-        Above, we specified the type of :class:`.DateTime` for the ``timestamp``
-        bind, and the type of :class:`.String` for the ``name`` bind.  In
-        the case of ``name`` we also set the default value of ``"jack"``.
-
-        Additional bound parameters can be supplied at statement execution

-            END
-
-        When simple equality expressions of several values against a single
-        parent column are needed, :func:`.case` also has a "shorthand" format
-        used via the
-        :paramref:`.case.value` parameter, which is passed a column
-        expression to be compared.  In this form, the :paramref:`.case.whens`
-        parameter is passed as a dictionary containing expressions to be compared
-        against keyed to result expressions.  The statement below is equivalent
-        to the preceding statement::

-
-        The values which are accepted as result values in
-        :paramref:`.case.whens` as well as with :paramref:`.case.else_` are
-        coerced from Python literals into :func:`.bindparam` constructs.
-        SQL expressions, e.g. :class:`.ColumnElement` constructs, are accepted
-        as well.  To coerce a literal string expression into a constant
-        expression rendered inline, use the :func:`.literal_column` construct,
-        as in::
-
-            from sqlalchemy import case, literal_column
-
-            case(

-                else_=literal_column("'lessthan10'")
-            )
-
-        The above will render the given constants without using bound
-        parameters for the result values (but still for the comparison
-        values), as in::
-
-            CASE
-                WHEN (orderline.qty > :qty_1) THEN 'greaterthan100'
-                WHEN (orderline.qty > :qty_2) THEN 'greaterthan10'
-                ELSE 'lessthan10'

-
-        :param whens: The criteria to be compared against, :paramref:`.case.whens`
-         accepts two different forms, based on whether or not :paramref:`.case.value`
-         is used.
-
-         In the first form, it accepts a list of 2-tuples; each 2-tuple consists
-         of ``(<sql expression>, <value>)``, where the SQL expression is a
-         boolean expression and "value" is a resulting value, e.g.::
-
-            case([
-                (users_table.c.name == 'wendy', 'W'),
-                (users_table.c.name == 'jack', 'J')
-            ])
-
-         In the second form, it accepts a Python dictionary of comparison values
-         mapped to a resulting value; this form requires :paramref:`.case.value`
-         to be present, and values will be compared using the ``==`` operator,
-         e.g.::
-
-            case(
-                {"wendy": "W", "jack": "J"},
-                value=users_table.c.name
-            )
-
-        :param value: An optional SQL expression which will be used as a
-          fixed "comparison point" for candidate values within a dictionary
-          passed to :paramref:`.case.whens`.
-

-          result of the ``CASE`` construct if all expressions within
-          :paramref:`.case.whens` evaluate to false.  When omitted, most

-
-    :class:`.quoted_name` is a Python unicode/str subclass which
-    represents a particular identifier name along with a
-    ``quote`` flag.  This ``quote`` flag, when set to
-    ``True`` or ``False``, overrides automatic quoting behavior
-    for this identifier in order to either unconditionally quote
-    or to not quote the name.  If left at its default of ``None``,
-    quoting behavior is applied to the identifier on a per-backend basis
-    based on an examination of the token itself.
-
-    A :class:`.quoted_name` object with ``quote=True`` is also
-    prevented from being modified in the case of a so-called
-    "name normalize" option.  Certain database backends, such as
-    Oracle, Firebird, and DB2 "normalize" case-insensitive names
-    as uppercase.  The SQLAlchemy dialects for these backends
-    convert from SQLAlchemy's lower-case-means-insensitive convention
-    to the upper-case-means-insensitive conventions of those backends.
-    The ``quote=True`` flag here will prevent this conversion from occurring
-    to support an identifier that's quoted as all lower case against
-    such a backend.
-
-    The :class:`.quoted_name` object is normally created automatically
-    when specifying the name for key schema constructs such as :class:`.Table`,
-    :class:`.Column`, and others.   The class can also be passed explicitly
-    as the name to any function that receives a name which can be quoted.
-    Such as to use the :meth:`.Engine.has_table` method with an unconditionally
-    quoted name::
-
-        from sqlaclchemy import create_engine
-        from sqlalchemy.sql.elements import quoted_name
-
-        engine = create_engine("oracle+cx_oracle://some_dsn")
-        engine.has_table(quoted_name("some_table", True))
-
-    The above logic will run the "has table" logic against the Oracle backend,
-    passing the name exactly as ``"some_table"`` without converting to
-    upper case.

-
-   :data:`.func` is a special object instance which generates SQL
-   functions based on name-based attributes, e.g.::
-
-        >>> print func.count(1)
-        count(:param_1)
-
-   The element is a column-oriented SQL element like any other, and is
-   used in that way::
-
-        >>> print select([func.count(table.c.id)])
-        SELECT count(sometable.id) FROM sometable
-
-   Any name can be given to :data:`.func`. If the function name is unknown to
-   SQLAlchemy, it will be rendered exactly as is. For common SQL functions
-   which SQLAlchemy is aware of, the name may be interpreted as a *generic
-   function* which will be compiled appropriately to the target database::
-
-        >>> print func.current_timestamp()
-        CURRENT_TIMESTAMP
-
-   To call functions which are present in dot-separated packages,
-   specify them in the same manner::
-
-        >>> print func.stats.yield_curve(5, 10)
-        stats.yield_curve(:yield_curve_1, :yield_curve_2)
-
-   SQLAlchemy can be made aware of the return type of functions to enable
-   type-specific lexical and result-based behavior. For example, to ensure
-   that a string-based function returns a Unicode value and is similarly
-   treated as a string in expressions, specify
-   :class:`~sqlalchemy.types.Unicode` as the type:
-
-        >>> print func.my_string(u'hi', type_=Unicode) + ' ' + \
-        ... func.my_string(u'there', type_=Unicode)
-        my_string(:my_string_1) || :my_string_2 || my_string(:my_string_3)
-
-   The object returned by a :data:`.func` call is usually an instance of
-   :class:`.Function`.
-   This object meets the "column" interface, including comparison and labeling
-   functions.  The object can also be passed the :meth:`~.Connectable.execute`
-   method of a :class:`.Connection` or :class:`.Engine`, where it will be
-   wrapped inside of a SELECT statement first::
-
-        print connection.execute(func.current_timestamp()).scalar()
-
-   In a few exception cases, the :data:`.func` accessor
-   will redirect a name to a built-in expression such as :func:`.cast`
-   or :func:`.extract`, as these names have well-known meaning
-   but are not exactly the same as "functions" from a SQLAlchemy
-   perspective.
-
-   .. versionadded:: 0.8 :data:`.func` can return non-function expression
-      constructs for common quasi-functional names like :func:`.cast`
-      and :func:`.extract`.

-
-    A generic function is a pre-established :class:`.Function`
-    class that is instantiated automatically when called
-    by name from the :data:`.func` attribute.    Note that
-    calling any name from :data:`.func` has the effect that
-    a new :class:`.Function` instance is created automatically,
-    given that name.  The primary use case for defining
-    a :class:`.GenericFunction` class is so that a function
-    of a particular name may be given a fixed return type.
-    It can also include custom argument parsing schemes as well
-    as additional methods.
-
-    Subclasses of :class:`.GenericFunction` are automatically
-    registered under the name of the class.  For
-    example, a user-defined function ``as_utc()`` would
-    be available immediately::
-
-        from sqlalchemy.sql.functions import GenericFunction
-        from sqlalchemy.types import DateTime
-
-        class as_utc(GenericFunction):
-            type = DateTime
-
-        print select([func.as_utc()])
-
-    User-defined generic functions can be organized into
-    packages by specifying the "package" attribute when defining
-    :class:`.GenericFunction`.   Third party libraries
-    containing many functions may want to use this in order
-    to avoid name conflicts with other systems.   For example,
-    if our ``as_utc()`` function were part of a package
-    "time"::
-
-        class as_utc(GenericFunction):
-            type = DateTime
-            package = "time"
-
-    The above function would be available from :data:`.func`
-    using the package name ``time``::
-
-        print select([func.time.as_utc()])
-
-    A final option is to allow the function to be accessed
-    from one name in :data:`.func` but to render as a different name.
-    The ``identifier`` attribute will override the name used to
-    access the function as loaded from :data:`.func`, but will retain
-    the usage of ``name`` as the rendered name::
-
-        class GeoBuffer(GenericFunction):
-            type = Geometry
-            package = "geo"
-            name = "ST_Buffer"
-            identifier = "buffer"
-
-    The above function will render as follows::
-
-        >>> print func.geo.buffer()
-        ST_Buffer()
-
-    .. versionadded:: 0.8 :class:`.GenericFunction` now supports
-       automatic registration of new functions as well as package
-       and custom naming support.
-
-    .. versionchanged:: 0.8 The attribute name ``type`` is used
-       to specify the function's return type at the class level.
-       Previously, the name ``__return_type__`` was used.  This
-       name is still recognized for backwards-compatibility.

-"""The schema module provides the building blocks for database metadata.
-
-Each element within this module describes a database entity which can be
-created and dropped, or is otherwise part of such an entity.  Examples include
-tables, columns, sequences, and indexes.
-
-All entities are subclasses of :class:`~sqlalchemy.schema.SchemaItem`, and as
-defined in this module they are intended to be agnostic of any vendor-specific
-constructs.
-
-A collection of entities are grouped into a unit called
-:class:`~sqlalchemy.schema.MetaData`. MetaData serves as a logical grouping of
-schema elements, and can also be associated with an actual database connection
-such that operations involving the contained elements can contact the database
-as needed.
-
-Two of the elements here also build upon their "syntactic" counterparts, which
-are defined in :class:`~sqlalchemy.sql.expression.`, specifically
-:class:`~sqlalchemy.schema.Table` and :class:`~sqlalchemy.schema.Column`.
-Since these objects are part of the SQL expression language, they are usable
-as components in SQL expressions.

-        mytable = Table("mytable", metadata,
-                        Column('mytable_id', Integer, primary_key=True),
-                        Column('value', String(50))
-                   )
-
-    The :class:`.Table` object constructs a unique instance of itself based
-    on its name and optional schema name within the given
-    :class:`.MetaData` object. Calling the :class:`.Table`
-    constructor with the same name and same :class:`.MetaData` argument
-    a second time will return the *same* :class:`.Table` object - in this way
-    the :class:`.Table` constructor acts as a registry function.
-
-    .. seealso::
-
-        :ref:`metadata_describing` - Introduction to database metadata
-
-    Constructor arguments are as follows:
-
-    :param name: The name of this table as represented in the database.
-
-        The table name, along with the value of the ``schema`` parameter,
-        forms a key which uniquely identifies this :class:`.Table` within
-        the owning :class:`.MetaData` collection.
-        Additional calls to :class:`.Table` with the same name, metadata,
-        and schema name will return the same :class:`.Table` object.
-
-        Names which contain no upper case characters
-        will be treated as case insensitive names, and will not be quoted
-        unless they are a reserved word or contain special characters.
-        A name with any number of upper case characters is considered
-        to be case sensitive, and will be sent as quoted.
-
-        To enable unconditional quoting for the table name, specify the flag
-        ``quote=True`` to the constructor, or use the :class:`.quoted_name`
-        construct to specify the name.
-
-    :param metadata: a :class:`.MetaData` object which will contain this
-        table.  The metadata is used as a point of association of this table
-        with other tables which are referenced via foreign key.  It also
-        may be used to associate this table with a particular
-        :class:`.Connectable`.
-
-    :param \*args: Additional positional arguments are used primarily
-        to add the list of :class:`.Column` objects contained within this
-        table. Similar to the style of a CREATE TABLE statement, other
-        :class:`.SchemaItem` constructs may be added here, including
-        :class:`.PrimaryKeyConstraint`, and :class:`.ForeignKeyConstraint`.
-
-    :param autoload: Defaults to False: the Columns for this table should
-        be reflected from the database. Usually there will be no Column
-        objects in the constructor if this property is set.
-
-    :param autoload_replace: If ``True``, when using ``autoload=True``
-        and ``extend_existing=True``,
-        replace ``Column`` objects already present in the ``Table`` that's
-        in the ``MetaData`` registry with
-        what's reflected.  Otherwise, all existing columns will be
-        excluded from the reflection process.    Note that this does
-        not impact ``Column`` objects specified in the same call to ``Table``
-        which includes ``autoload``, those always take precedence.
-        Defaults to ``True``.
-
-        .. versionadded:: 0.7.5
-
-    :param autoload_with: If autoload==True, this is an optional Engine
-        or Connection instance to be used for the table reflection. If
-        ``None``, the underlying MetaData's bound connectable will be used.
-
-    :param extend_existing: When ``True``, indicates that if this
-        :class:`.Table` is already present in the given :class:`.MetaData`,
-        apply further arguments within the constructor to the existing
-        :class:`.Table`.
-
-        If ``extend_existing`` or ``keep_existing`` are not set, an error is
-        raised if additional table modifiers are specified when
-        the given :class:`.Table` is already present in the :class:`.MetaData`.
-
-        .. versionchanged:: 0.7.4
-            ``extend_existing`` will work in conjunction
-            with ``autoload=True`` to run a new reflection operation against
-            the database; new :class:`.Column` objects will be produced
-            from database metadata to replace those existing with the same
-            name, and additional :class:`.Column` objects not present
-            in the :class:`.Table` will be added.
-
-        As is always the case with ``autoload=True``, :class:`.Column`
-        objects can be specified in the same :class:`.Table` constructor,
-        which will take precedence.  I.e.::
-
-            Table("mytable", metadata,
-                        Column('y', Integer),
-                        extend_existing=True,
-                        autoload=True,
-                        autoload_with=engine
-                    )
-
-        The above will overwrite all columns within ``mytable`` which
-        are present in the database, except for ``y`` which will be used as is
-        from the above definition.   If the ``autoload_replace`` flag
-        is set to False, no existing columns will be replaced.
-
-    :param implicit_returning: True by default - indicates that
-        RETURNING can be used by default to fetch newly inserted primary key
-        values, for backends which support this.  Note that
-        create_engine() also provides an implicit_returning flag.
-
-    :param include_columns: A list of strings indicating a subset of
-        columns to be loaded via the ``autoload`` operation; table columns who
-        aren't present in this list will not be represented on the resulting
-        ``Table`` object. Defaults to ``None`` which indicates all columns
-        should be reflected.
-
-    :param info: Optional data dictionary which will be populated into the
-        :attr:`.SchemaItem.info` attribute of this object.
-
-    :param keep_existing: When ``True``, indicates that if this Table
-        is already present in the given :class:`.MetaData`, ignore
-        further arguments within the constructor to the existing
-        :class:`.Table`, and return the :class:`.Table` object as
-        originally created. This is to allow a function that wishes
-        to define a new :class:`.Table` on first call, but on
-        subsequent calls will return the same :class:`.Table`,
-        without any of the declarations (particularly constraints)
-        being applied a second time. Also see extend_existing.
-
-        If extend_existing or keep_existing are not set, an error is
-        raised if additional table modifiers are specified when
-        the given :class:`.Table` is already present in the :class:`.MetaData`.
-
-    :param listeners: A list of tuples of the form ``(<eventname>, <fn>)``
-        which will be passed to :func:`.event.listen` upon construction.
-        This alternate hook to :func:`.event.listen` allows the establishment
-        of a listener function specific to this :class:`.Table` before
-        the "autoload" process begins.  Particularly useful for
-        the :meth:`.DDLEvents.column_reflect` event::
-
-            def listen_for_reflect(table, column_info):
-                "handle the column reflection event"
-                # ...
-
-            t = Table(
-                'sometable',
-                autoload=True,
-                listeners=[
-                    ('column_reflect', listen_for_reflect)
-                ])
-
-    :param mustexist: When ``True``, indicates that this Table must already
-        be present in the given :class:`.MetaData` collection, else
-        an exception is raised.
-
-    :param prefixes:
-        A list of strings to insert after CREATE in the CREATE TABLE
-        statement.  They will be separated by spaces.
-
-    :param quote: Force quoting of this table's name on or off, corresponding
-        to ``True`` or ``False``.  When left at its default of ``None``,
-        the column identifier will be quoted according to whether the name is
-        case sensitive (identifiers with at least one upper case character are
-        treated as case sensitive), or if it's a reserved word.  This flag
-        is only needed to force quoting of a reserved word which is not known
-        by the SQLAlchemy dialect.
-
-    :param quote_schema: same as 'quote' but applies to the schema identifier.
-
-    :param schema: The schema name for this table, which is required if
-        the table resides in a schema other than the default selected schema
-        for the engine's database connection.  Defaults to ``None``.
-
-        The quoting rules for the schema name are the same as those for the
-        ``name`` parameter, in that quoting is applied for reserved words or
-        case-sensitive names; to enable unconditional quoting for the
-        schema name, specify the flag
-        ``quote_schema=True`` to the constructor, or use the :class:`.quoted_name`
-        construct to specify the name.
-
-    :param useexisting: Deprecated.  Use extend_existing.
-
-    :param \**kw: Additional keyword arguments not mentioned above are
-        dialect specific, and passed in the form ``<dialectname>_<argname>``.
-        See the documentation regarding an individual dialect at
-        :ref:`dialect_toplevel` for detail on documented arguments.

-
-          Names which contain no upper case characters
-          will be treated as case insensitive names, and will not be quoted

-          behavior applies even for databases which standardize upper
-          case names as case insensitive such as Oracle.
-
-          The name field may be omitted at construction time and applied

-        :param \*args: Additional positional arguments include various
-          :class:`.SchemaItem` derived constructs which will be applied
-          as options to the column.  These include instances of
-          :class:`.Constraint`, :class:`.ForeignKey`, :class:`.ColumnDefault`,
-          and :class:`.Sequence`.  In some cases an equivalent keyword
-          argument is available such as ``server_default``, ``default``
-          and ``unique``.
-
-        :param autoincrement: This flag may be set to ``False`` to
-          indicate an integer primary key column that should not be
-          considered to be the "autoincrement" column, that is
-          the integer primary key column which generates values
-          implicitly upon INSERT and whose value is usually returned
-          via the DBAPI cursor.lastrowid attribute.   It defaults
-          to ``True`` to satisfy the common use case of a table
-          with a single integer primary key column.  If the table
-          has a composite primary key consisting of more than one
-          integer column, set this flag to True only on the
-          column that should be considered "autoincrement".
-
-          The setting *only* has an effect for columns which are:
-
-          * Integer derived (i.e. INT, SMALLINT, BIGINT).
-
-          * Part of the primary key
-
-          * Are not referenced by any foreign keys, unless

-
-          * have no server side or client side defaults (with the exception
-            of Postgresql SERIAL).
-
-          The setting has these two effects on columns that meet the
-          above criteria:
-
-          * DDL issued for the column will include database-specific
-            keywords intended to signify this column as an
-            "autoincrement" column, such as AUTO INCREMENT on MySQL,
-            SERIAL on Postgresql, and IDENTITY on MS-SQL.  It does
-            *not* issue AUTOINCREMENT for SQLite since this is a
-            special SQLite flag that is not required for autoincrementing
-            behavior.  See the SQLite dialect documentation for
-            information on SQLite's AUTOINCREMENT.
-
-          * The column will be considered to be available as
-            cursor.lastrowid or equivalent, for those dialects which
-            "post fetch" newly inserted identifiers after a row has
-            been inserted (SQLite, MySQL, MS-SQL).  It does not have
-            any effect in this regard for databases that use sequences
-            to generate primary key identifiers (i.e. Firebird, Postgresql,
-            Oracle).
-
-          .. versionchanged:: 0.7.4
-              ``autoincrement`` accepts a special value ``'ignore_fk'``
-              to indicate that autoincrementing status regardless of foreign
-              key references.  This applies to certain composite foreign key
-              setups, such as the one demonstrated in the ORM documentation
-              at :ref:`post_update`.
-
-        :param default: A scalar, Python callable, or
-            :class:`.ColumnElement` expression representing the
-            *default value* for this column, which will be invoked upon insert
-            if this column is otherwise not specified in the VALUES clause of
-            the insert. This is a shortcut to using :class:`.ColumnDefault` as
-            a positional argument; see that class for full detail on the
-            structure of the argument.
-
-            Contrast this argument to ``server_default`` which creates a
-            default generator on the database side.
-
-        :param doc: optional String that can be used by the ORM or similar
-            to document attributes.   This attribute does not render SQL
-            comments (a future attribute 'comment' will achieve that).
-
-        :param key: An optional string identifier which will identify this
-            ``Column`` object on the :class:`.Table`. When a key is provided,
-            this is the only identifier referencing the ``Column`` within the
-            application, including ORM attribute mapping; the ``name`` field
-            is used only when rendering SQL.
-
-        :param index: When ``True``, indicates that the column is indexed.
-            This is a shortcut for using a :class:`.Index` construct on the
-            table. To specify indexes with explicit names or indexes that
-            contain multiple columns, use the :class:`.Index` construct
-            instead.
-
-        :param info: Optional data dictionary which will be populated into the
-            :attr:`.SchemaItem.info` attribute of this object.
-
-        :param nullable: If set to the default of ``True``, indicates the
-            column will be rendered as allowing NULL, else it's rendered as
-            NOT NULL. This parameter is only used when issuing CREATE TABLE
-            statements.
-
-        :param onupdate: A scalar, Python callable, or
-            :class:`~sqlalchemy.sql.expression.ClauseElement` representing a
-            default value to be applied to the column within UPDATE
-            statements, which wil be invoked upon update if this column is not
-            present in the SET clause of the update. This is a shortcut to
-            using :class:`.ColumnDefault` as a positional argument with
-            ``for_update=True``.
-
-        :param primary_key: If ``True``, marks this column as a primary key
-            column. Multiple columns can have this flag set to specify
-            composite primary keys. As an alternative, the primary key of a
-            :class:`.Table` can be specified via an explicit
-            :class:`.PrimaryKeyConstraint` object.
-
-        :param server_default: A :class:`.FetchedValue` instance, str, Unicode
-            or :func:`~sqlalchemy.sql.expression.text` construct representing
-            the DDL DEFAULT value for the column.
-
-            String types will be emitted as-is, surrounded by single quotes::
-
-                Column('x', Text, server_default="val")
-
-                x TEXT DEFAULT 'val'
-
-            A :func:`~sqlalchemy.sql.expression.text` expression will be
-            rendered as-is, without quotes::
-
-                Column('y', DateTime, server_default=text('NOW()'))
-
-                y DATETIME DEFAULT NOW()
-
-            Strings and text() will be converted into a :class:`.DefaultClause`
-            object upon initialization.
-
-            Use :class:`.FetchedValue` to indicate that an already-existing
-            column will generate a default value on the database side which
-            will be available to SQLAlchemy for post-fetch after inserts. This
-            construct does not specify any DDL and the implementation is left
-            to the database, such as via a trigger.
-
-        :param server_onupdate:   A :class:`.FetchedValue` instance
-             representing a database-side default generation function. This
-             indicates to SQLAlchemy that a newly generated value will be
-             available after updates. This construct does not specify any DDL
-             and the implementation is left to the database, such as via a
-             trigger.
-
-        :param quote: Force quoting of this column's name on or off,
-             corresponding to ``True`` or ``False``. When left at its default
-             of ``None``, the column identifier will be quoted according to
-             whether the name is case sensitive (identifiers with at least one
-             upper case character are treated as case sensitive), or if it's a
-             reserved word. This flag is only needed to force quoting of a
-             reserved word which is not known by the SQLAlchemy dialect.
-
-        :param unique: When ``True``, indicates that this column contains a
-             unique constraint, or if ``index`` is ``True`` as well, indicates
-             that the :class:`.Index` should be created with the unique flag.
-             To specify multiple columns in the constraint/index or to specify
-             an explicit name, use the :class:`.UniqueConstraint` or
-             :class:`.Index` constructs explicitly.
-
-        :param system: When ``True``, indicates this is a "system" column,
-             that is a column which is automatically made available by the
-             database, and should not be included in the columns list for a
-             ``CREATE TABLE`` statement.

-
-          The keys of this dictionary may be:
-
-          * a constraint or Index class, e.g. the :class:`.UniqueConstraint`,
-            :class:`.ForeignKeyConstraint` class, the :class:`.Index` class
-
-          * a string mnemonic for one of the known constraint classes;
-            ``"fk"``, ``"pk"``, ``"ix"``, ``"ck"``, ``"uq"`` for foreign key,
-            primary key, index, check, and unique constraint, respectively.
-
-          * the string name of a user-defined "token" that can be used
-            to define new naming tokens.
-
-          The values associated with each "constraint class" or "constraint
-          mnemonic" key are string naming templates, such as
-          ``"uq_%(table_name)s_%(column_0_name)s"``,
-          which decribe how the name should be composed.  The values associated
-          with user-defined "token" keys should be callables of the form
-          ``fn(constraint, table)``, which accepts the constraint/index
-          object and :class:`.Table` as arguments, returning a string
-          result.
-
-          The built-in names are as follows, some of which may only be
-          available for certain types of constraint:
-
-            * ``%(table_name)s`` - the name of the :class:`.Table` object
-              associated with the constraint.
-
-            * ``%(referred_table_name)s`` - the name of the :class:`.Table`
-              object associated with the referencing target of a
-              :class:`.ForeignKeyConstraint`.
-
-            * ``%(column_0_name)s`` - the name of the :class:`.Column` at
-              index position "0" within the constraint.
-
-            * ``%(column_0_label)s`` - the label of the :class:`.Column` at
-              index position "0", e.g. :attr:`.Column.label`
-
-            * ``%(column_0_key)s`` - the key of the :class:`.Column` at
-              index position "0", e.g. :attr:`.Column.key`
-
-            * ``%(referred_column_0_name)s`` - the name of a :class:`.Column`
-              at index position "0" referenced by a :class:`.ForeignKeyConstraint`.
-
-            * ``%(constraint_name)s`` - a special key that refers to the existing
-              name given to the constraint.  When this key is present, the
-              :class:`.Constraint` object's existing name will be replaced with
-              one that is composed from template string that uses this token.
-              When this token is present, it is required that the :class:`.Constraint`
-              is given an expicit name ahead of time.
-
-            * user-defined: any additional token may be implemented by passing
-              it along with a ``fn(constraint, table)`` callable to the

-        """return an alias of this :class:`.Join`.
-
-        The default behavior here is to first produce a SELECT
-        construct from this :class:`.Join`, then to produce a
-        :class:`.Alias` from that.  So given a join of the form::
-
-            j = table_a.join(table_b, table_a.c.id == table_b.c.a_id)
-
-        The JOIN by itself would look like::
-
-            table_a JOIN table_b ON table_a.id = table_b.a_id
-
-        Whereas the alias of the above, ``j.alias()``, would in a
-        SELECT context look like::
-
-            (SELECT table_a.id AS table_a_id, table_b.id AS table_b_id,
-                table_b.a_id AS table_b_a_id
-                FROM table_a
-                JOIN table_b ON table_a.id = table_b.a_id) AS anon_1
-
-        The equivalent long-hand form, given a :class:`.Join` object
-        ``j``, is::
-
-            from sqlalchemy import select, alias
-            j = alias(
-                select([j.left, j.right]).\\
-                    select_from(j).\\
-                    with_labels(True).\\
-                    correlate(False),
-                name=name
-            )
-
-        The selectable produced by :meth:`.Join.alias` features the same
-        columns as that of the two individual selectables presented under
-        a single name - the individual columns are "auto-labeled", meaning
-        the ``.c.`` collection of the resulting :class:`.Alias` represents
-        the names of the individual columns using a ``<tablename>_<columname>``
-        scheme::
-
-            j.c.table_a_id
-            j.c.table_b_a_id
-
-        :meth:`.Join.alias` also features an alternate
-        option for aliasing joins which produces no enclosing SELECT and
-        does not normally apply labels to the column names.  The
-        ``flat=True`` option will call :meth:`.FromClause.alias`
-        against the left and right sides individually.
-        Using this option, no new ``SELECT`` is produced;
-        we instead, from a construct as below::
-
-            j = table_a.join(table_b, table_a.c.id == table_b.c.a_id)
-            j = j.alias(flat=True)
-
-        we get a result like this::
-
-            table_a AS table_a_1 JOIN table_b AS table_b_1 ON
-            table_a_1.id = table_b_1.a_id
-
-        The ``flat=True`` argument is also propagated to the contained
-        selectables, so that a composite join such as::
-
-            j = table_a.join(
-                    table_b.join(table_c,
-                            table_b.c.id == table_c.c.b_id),
-                    table_b.c.a_id == table_a.c.id
-                ).alias(flat=True)
-
-        Will produce an expression like::
-
-            table_a AS table_a_1 JOIN (
-                    table_b AS table_b_1 JOIN table_c AS table_c_1
-                    ON table_b_1.id = table_c_1.b_id
-            ) ON table_a_1.id = table_b_1.a_id
-
-        The standalone :func:`~.expression.alias` function as well as the
-        base :meth:`.FromClause.alias` method also support the ``flat=True``
-        argument as a no-op, so that the argument can be passed to the
-        ``alias()`` method of any selectable.
-
-        .. versionadded:: 0.9.0 Added the ``flat=True`` option to create
-          "aliases" of joins without enclosing inside of a SELECT
-          subquery.

-            Due to a bug fix, this method has a slight
-            behavioral change as of version 0.7.3.
-            Prior to version 0.7.3, the FROM clause of
-            a :func:`.select` was calculated upfront and as new columns
-            were added; in 0.7.3 and later it's calculated
-            at compile time, fixing an issue regarding late binding
-            of columns to parent tables.  This changes the behavior of
-            :meth:`.Select.with_only_columns` in that FROM clauses no
-            longer represented in the new list are dropped,
-            but this behavior is more consistent in
-            that the FROM clauses are consistently derived from the
-            current columns clause.  The original intent of this method
-            is to allow trimming of the existing columns list to be fewer
-            columns than originally present; the use case of replacing
-            the columns list with an entirely different one hadn't
-            been anticipated until 0.7.3 was released; the usage
-            guidelines below illustrate how this should be done.
-
-        This method is exactly equivalent to as if the original
-        :func:`.select` had been called with the given columns
-        clause.   I.e. a statement::
-
-            s = select([table1.c.a, table1.c.b])
-            s = s.with_only_columns([table1.c.b])
-
-        should be exactly equivalent to::
-
-            s = select([table1.c.b])
-
-        This means that FROM clauses which are only derived
-        from the column list will be discarded if the new column
-        list no longer contains that FROM::
-
-            >>> table1 = table('t1', column('a'), column('b'))
-            >>> table2 = table('t2', column('a'), column('b'))
-            >>> s1 = select([table1.c.a, table2.c.b])
-            >>> print s1
-            SELECT t1.a, t2.b FROM t1, t2
-            >>> s2 = s1.with_only_columns([table2.c.b])
-            >>> print s2
-            SELECT t2.b FROM t1
-
-        The preferred way to maintain a specific FROM clause
-        in the construct, assuming it won't be represented anywhere
-        else (i.e. not in the WHERE clause, etc.) is to set it using
-        :meth:`.Select.select_from`::
-
-            >>> s1 = select([table1.c.a, table2.c.b]).\\
-            ...         select_from(table1.join(table2,
-            ...                 table1.c.a==table2.c.a))
-            >>> s2 = s1.with_only_columns([table2.c.b])
-            >>> print s2
-            SELECT t2.b FROM t1 JOIN t2 ON t1.a=t2.a
-
-        Care should also be taken to use the correct
-        set of column objects passed to :meth:`.Select.with_only_columns`.
-        Since the method is essentially equivalent to calling the
-        :func:`.select` construct in the first place with the given
-        columns, the columns passed to :meth:`.Select.with_only_columns`
-        should usually be a subset of those which were passed
-        to the :func:`.select` construct, not those which are available
-        from the ``.c`` collection of that :func:`.select`.  That
-        is::
-
-            s = select([table1.c.a, table1.c.b]).select_from(table1)
-            s = s.with_only_columns([table1.c.b])
-
-        and **not**::
-
-            # usually incorrect
-            s = s.with_only_columns([s.c.b])
-
-        The latter would produce the SQL::
-
-            SELECT b
-            FROM (SELECT t1.a AS a, t1.b AS b
-            FROM t1), t1
-
-        Since the :func:`.select` construct is essentially being
-        asked to select both from ``table1`` as well as itself.

-          If the DBAPI in use does not support Python unicode
-          (which is fewer and fewer these days), SQLAlchemy
-          will encode/decode the value, using the

-
-          When using a DBAPI that natively supports Python
-          unicode objects, this flag generally does not

-          intended to store non-ASCII data, the :class:`.Unicode`
-          or :class:`.UnicodeText`
-          types should be used regardless, which feature
-          the same behavior of ``convert_unicode`` but
-          also indicate an underlying column type that
-          directly supports unicode, such as ``NVARCHAR``.
-
-          For the extremely rare case that Python ``unicode``
-          is to be encoded/decoded by SQLAlchemy on a backend
-          that does natively support Python ``unicode``,
-          the value ``force`` can be passed here which will

-          SQLAlchemy is not guaranteed to handle the task of unicode

-    The :class:`.Unicode` type is a :class:`.String` subclass
-    that assumes input and output as Python ``unicode`` data,
-    and in that regard is equivalent to the usage of the
-    ``convert_unicode`` flag with the :class:`.String` type.
-    However, unlike plain :class:`.String`, it also implies an
-    underlying column type that is explicitly supporting of non-ASCII
-    data, such as ``NVARCHAR`` on Oracle and SQL Server.
-    This can impact the output of ``CREATE TABLE`` statements
-    and ``CAST`` functions at the dialect level, and can
-    also affect the handling of bound parameters in some
-    specific DBAPI scenarios.
-
-    The encoding used by the :class:`.Unicode` type is usually
-    determined by the DBAPI itself; most modern DBAPIs
-    feature support for Python ``unicode`` objects as bound
-    values and result set values, and the encoding should
-    be configured as detailed in the notes for the target
-    DBAPI in the :ref:`dialect_toplevel` section.
-
-    For those DBAPIs which do not support, or are not configured
-    to accommodate Python ``unicode`` objects
-    directly, SQLAlchemy does the encoding and decoding
-    outside of the DBAPI.   The encoding in this scenario
-    is determined by the ``encoding`` flag passed to
-    :func:`.create_engine`.
-
-    When using the :class:`.Unicode` type, it is only appropriate
-    to pass Python ``unicode`` objects, and not plain ``str``.
-    If a plain ``str`` is passed under Python 2, a warning
-    is emitted.  If you notice your application emitting these warnings but
-    you're not sure of the source of them, the Python
-    ``warnings`` filter, documented at
-    http://docs.python.org/library/warnings.html,
-    can be used to turn these warnings into exceptions
-    which will illustrate a stack trace::
-
-      import warnings
-      warnings.simplefilter('error')
-
-    For an application that wishes to pass plain bytestrings
-    and Python ``unicode`` objects to the ``Unicode`` type
-    equally, the bytestrings must first be decoded into
-    unicode.  The recipe at :ref:`coerce_to_unicode` illustrates
-    how this is done.

-
-    This method is preferred to direct subclassing of SQLAlchemy's

-
-    Typical usage::
-
-      import sqlalchemy.types as types
-
-      class MyType(types.TypeDecorator):
-          '''Prefixes Unicode values with "PREFIX:" on the way in and

-
-          def copy(self):
-              return MyType(self.impl.length)
-
-    The class-level "impl" attribute is required, and can reference any
-    TypeEngine class.  Alternatively, the load_dialect_impl() method
-    can be used to provide different type classes based on the dialect
-    given; in this case, the "impl" variable can reference
-    ``TypeEngine`` as a placeholder.
-
-    Types that receive a Python type that isn't similar to the ultimate type
-    used may want to define the :meth:`TypeDecorator.coerce_compared_value`
-    method. This is used to give the expression system a hint when coercing
-    Python objects into bind parameters within expressions. Consider this
-    expression::
-
-        mytable.c.somecol + datetime.date(2009, 5, 15)
-
-    Above, if "somecol" is an ``Integer`` variant, it makes sense that
-    we're doing date arithmetic, where above is usually interpreted
-    by databases as adding a number of days to the given date.
-    The expression system does the right thing by not attempting to
-    coerce the "date()" value into an integer-oriented bind parameter.
-
-    However, in the case of ``TypeDecorator``, we are usually changing an
-    incoming Python type to something new - ``TypeDecorator`` by default will
-    "coerce" the non-typed side to be the same type as itself. Such as below,
-    we define an "epoch" type that stores a date value as an integer::
-
-        class MyEpochType(types.TypeDecorator):
-            impl = types.Integer
-
-            epoch = datetime.date(1970, 1, 1)
-
-            def process_bind_param(self, value, dialect):
-                return (value - self.epoch).days
-
-            def process_result_value(self, value, dialect):
-                return self.epoch + timedelta(days=value)
-
-    Our expression of ``somecol + date`` with the above type will coerce the

-"""Visitor/traversal interface and library functions.
-
-SQLAlchemy schema and expression constructs rely on a Python-centric
-version of the classic "visitor" pattern as the primary way in which
-they apply functionality.  The most common use of this pattern
-is statement compilation, where individual expression classes match
-up to rendering methods that produce a string result.   Beyond this,
-the visitor system is also used to inspect expressions for various
-information and patterns, as well as for usage in
-some kinds of expression transformation.  Other kinds of transformation
-use a non-visitor traversal system.
-
-For many examples of how the visit system is used, see the
-sqlalchemy.sql.util and the sqlalchemy.sql.compiler modules.
-For an introduction to clause adaption, see
-http://techspot.zzzeek.org/2008/01/23/expression-transformations/

-Nose test runner module.
-
-This script is a front-end to "nosetests" which
-installs SQLAlchemy's testing plugin into the local environment.
-
-The script is intended to be used by third-party dialects and extensions
-that run within SQLAlchemy's testing framework.    The runner can
-be invoked via::
-
-    python -m sqlalchemy.testing.runner
-
-The script is then essentially the same as the "nosetests" script, including
-all of the usual Nose options.   The test environment requires that a
-setup.cfg is locally present including various required options.
-
-Note that when using this runner, Nose's "coverage" plugin will not be
-able to provide coverage for SQLAlchemy itself, since SQLAlchemy is
-imported into sys.modules before coverage is started.   The special
-script sqla_nose.py is provided as a top-level script which loads the
-plugin in a special (somewhat hacky) way so that coverage against
-SQLAlchemy itself is possible.

-"""An adaptation of Py2.3/2.4's Queue module which supports reentrant
-behavior, using RLock instead of Lock for its mutex object.  The
-Queue object is used exclusively by the sqlalchemy.pool.QueuePool
-class.
-
-This is to support the connection pool's usage of weakref callbacks to return
-connections to the underlying Queue, which can in extremely
-rare cases be invoked within the ``get()`` method of the Queue itself,
-producing a ``put()`` inside the ``get()`` and therefore a reentrant
-condition.

-"""Append module search paths for third-party packages to sys.path.
-
-****************************************************************
-* This module is automatically imported during initialization. *
-****************************************************************
-
-In earlier versions of Python (up to 1.5a3), scripts or modules that
-needed to use site-specific modules would place ``import site''
-somewhere near the top of their code.  Because of the automatic
-import, this is no longer necessary (but code that does it still
-works).
-
-This will append site-specific paths to the module search path.  On
-Unix (including Mac OSX), it starts with sys.prefix and
-sys.exec_prefix (if different) and appends
-lib/python<version>/site-packages as well as lib/site-python.
-On other platforms (such as Windows), it tries each of the
-prefixes directly, as well as with lib/site-packages appended.  The
-resulting directories, if they exist, are appended to sys.path, and
-also inspected for path configuration files.
-
-A path configuration file is a file whose name has the form
-<package>.pth; its contents are additional directories (one per line)
-to be added to sys.path.  Non-existing directories (or
-non-directories) are never added to sys.path; no directory is added to
-sys.path more than once.  Blank lines and lines beginning with
-'#' are skipped. Lines starting with 'import' are executed.
-
-For example, suppose sys.prefix and sys.exec_prefix are set to
-/usr/local and there is a directory /usr/local/lib/python2.5/site-packages
-with three subdirectories, foo, bar and spam, and two path
-configuration files, foo.pth and bar.pth.  Assume foo.pth contains the
-following:
-
-  # foo package configuration
-  foo
-  bar
-  bletch
-
-and bar.pth contains:
-
-  # bar package configuration
-  bar
-
-Then the following directories are added to sys.path, in this order:
-
-  /usr/local/lib/python2.5/site-packages/bar
-  /usr/local/lib/python2.5/site-packages/foo
-
-Note that bletch is omitted because it doesn't exist; bar precedes foo
-because bar.pth comes alphabetically before foo.pth; and spam is
-omitted because it is not mentioned in either path configuration file.
-
-After these path manipulations, an attempt is made to import a module
-named sitecustomize, which can perform arbitrary additional
-site-specific customizations.  If this import fails with an
-ImportError exception, it is silently ignored.

-# Overview:
-#
-# This file implements the minimal SMTP protocol as defined in RFC 821.  It
-# has a hierarchy of classes which implement the backend functionality for the
-# smtpd.  A number of classes are provided:
-#
-#   SMTPServer - the base class for the backend.  Raises NotImplementedError
-#   if you try to use it.
-#
-#   DebuggingServer - simply prints each message it receives on stdout.
-#
-#   PureProxy - Proxies all messages to a real smtpd which does final
-#   delivery.  One known problem with this class is that it doesn't handle
-#   SMTP errors from the backend server at all.  This should be fixed
-#   (contributions are welcome!).
-#
-#   MailmanProxy - An experimental hack to work with GNU Mailman
-#   <www.list.org>.  Using this server as your real incoming smtpd, your
-#   mailhost will automatically recognize and accept mail destined to Mailman
-#   lists when those lists are created.  Every message not destined for a list
-#   gets forwarded to a real backend smtpd, as with PureProxy.  Again, errors
-#   are not handled correctly yet.
-#
-# Please note that this script requires Python 2.0
-#

-"""Routines to help recognizing sound files.
-
-Function whathdr() recognizes various types of sound file headers.
-It understands almost all headers that SOX can decode.
-
-The return tuple contains the following items, in this order:
-- file type (as SOX understands it)
-- sampling rate (0 if unknown or hard to decode)
-- number of channels (0 if unknown or hard to decode)
-- number of frames in the file (-1 if unknown or hard to decode)
-- number of bits/sample, or 'U' for U-LAW, or 'A' for A-LAW
-
-If the file doesn't have a recognizable type, it returns None.
-If the file can't be opened, IOError is raised.
-
-To compute the total time, divide the number of frames by the
-sampling rate (a frame contains a sample for each channel).
-
-Function what() calls whathdr().  (It used to also use some
-heuristics for raw data, but this doesn't work very well.)
-
-Finally, the function test() is a simple main program that calls
-what() for all files mentioned on the argument list.  For directory
-arguments it calls what() for all files in that directory.  Default
-argument is "." (testing all files in the current directory).  The
-option -r tells it to recurse down directories found inside

-# Wrapper module for _socket, providing some additional facilities
-# implemented in Python.
-
-"""\
-This module provides socket operations and some related functions.
-On Unix, it supports IP (Internet Protocol) and Unix domain sockets.
-On other systems, it only supports IP. Functions specific for a
-socket are available as methods of the socket object.
-
-Functions:
-
-socket() -- create a new socket object
-socketpair() -- create a pair of new socket objects [*]
-fromfd() -- create a socket object from an open file descriptor [*]
-gethostname() -- return the current hostname
-gethostbyname() -- map a hostname to its IP number
-gethostbyaddr() -- map an IP number or hostname to DNS info
-getservbyname() -- map a service name and a protocol name to a port number
-getprotobyname() -- map a protocol name (e.g. 'tcp') to a number
-ntohs(), ntohl() -- convert 16, 32 bit int from network to host byte order
-htons(), htonl() -- convert 16, 32 bit int from host to network byte order
-inet_aton() -- convert IP addr string (123.45.67.89) to 32-bit packed format
-inet_ntoa() -- convert 32-bit packed format IP to string (123.45.67.89)
-ssl() -- secure socket layer support (only available if configured)
-socket.getdefaulttimeout() -- get the default timeout value
-socket.setdefaulttimeout() -- set the default timeout value
-create_connection() -- connects to an address, with an optional timeout and
-                       optional source address.
-
- [*] not available on all platforms!
-
-Special objects:
-
-SocketType -- type object for socket objects
-error -- exception raised for I/O errors
-has_ipv6 -- boolean value indicating if IPv6 is supported
-
-Integer constants:
-
-AF_INET, AF_UNIX -- socket domains (first argument to socket() call)
-SOCK_STREAM, SOCK_DGRAM, SOCK_RAW -- socket types (second argument)
-
-Many other constants may be defined; these may be used in calls to
-the setsockopt() and getsockopt() methods.

-# Wrapper module for _ssl, providing some additional facilities
-# implemented in Python.  Written by Bill Janssen.
-
-"""\
-This module provides some more Pythonic support for SSL.
-
-Object types:
-
-  SSLSocket -- subtype of socket.socket which does SSL over the socket
-
-Exceptions:
-
-  SSLError -- exception raised for I/O errors
-
-Functions:
-
-  cert_time_to_seconds -- convert time string used for certificate
-                          notBefore and notAfter functions to integer
-                          seconds past the Epoch (the time values
-                          returned from time.time())
-
-  fetch_server_certificate (HOST, PORT) -- fetch the certificate provided
-                          by the server running on HOST at port PORT.  No
-                          validation of the certificate is performed.
-
-Integer constants:
-
-SSL_ERROR_ZERO_RETURN
-SSL_ERROR_WANT_READ
-SSL_ERROR_WANT_WRITE
-SSL_ERROR_WANT_X509_LOOKUP
-SSL_ERROR_SYSCALL
-SSL_ERROR_SSL
-SSL_ERROR_WANT_CONNECT
-
-SSL_ERROR_EOF
-SSL_ERROR_INVALID_ERROR_CODE
-
-The following group define certificate requirements that one side is
-allowing/requiring from the other side:
-
-CERT_NONE - no certificates from the other side are required (or will
-            be looked at if provided)
-CERT_OPTIONAL - certificates are not required, but if provided will be
-                validated, and if validation fails, the connection will
-                also fail
-CERT_REQUIRED - certificates are required, and will be validated, and
-                if validation fails, the connection will also fail
-
-The following constants identify various SSL protocol variants:
-
-PROTOCOL_SSLv2
-PROTOCOL_SSLv3
-PROTOCOL_SSLv23
-PROTOCOL_TLSv1

-r"""subprocess - Subprocesses with accessible I/O streams
-
-This module allows you to spawn processes, connect to their
-input/output/error pipes, and obtain their return codes.  This module
-intends to replace several other, older modules and functions, like:
-
-os.system
-os.spawn*
-os.popen*
-popen2.*
-commands.*
-
-Information about how the subprocess module can be used to replace these
-modules and functions can be found below.
-
-
-
-Using the subprocess module
-===========================
-This module defines one class called Popen:
-
-class Popen(args, bufsize=0, executable=None,
-            stdin=None, stdout=None, stderr=None,
-            preexec_fn=None, close_fds=False, shell=False,
-            cwd=None, env=None, universal_newlines=False,
-            startupinfo=None, creationflags=0):
-
-
-Arguments are:
-
-args should be a string, or a sequence of program arguments.  The
-program to execute is normally the first item in the args sequence or
-string, but can be explicitly set by using the executable argument.
-
-On UNIX, with shell=False (default): In this case, the Popen class
-uses os.execvp() to execute the child program.  args should normally
-be a sequence.  A string will be treated as a sequence with the string
-as the only item (the program to execute).
-
-On UNIX, with shell=True: If args is a string, it specifies the
-command string to execute through the shell.  If args is a sequence,
-the first item specifies the command string, and any additional items
-will be treated as additional shell arguments.
-
-On Windows: the Popen class uses CreateProcess() to execute the child
-program, which operates on strings.  If args is a sequence, it will be
-converted to a string using the list2cmdline method.  Please note that
-not all MS Windows applications interpret the command line the same
-way: The list2cmdline is designed for applications using the same
-rules as the MS C runtime.
-
-bufsize, if given, has the same meaning as the corresponding argument
-to the built-in open() function: 0 means unbuffered, 1 means line
-buffered, any other positive value means use a buffer of
-(approximately) that size.  A negative bufsize means to use the system
-default, which usually means fully buffered.  The default value for
-bufsize is 0 (unbuffered).
-
-stdin, stdout and stderr specify the executed programs' standard
-input, standard output and standard error file handles, respectively.
-Valid values are PIPE, an existing file descriptor (a positive
-integer), an existing file object, and None.  PIPE indicates that a
-new pipe to the child should be created.  With None, no redirection
-will occur; the child's file handles will be inherited from the
-parent.  Additionally, stderr can be STDOUT, which indicates that the
-stderr data from the applications should be captured into the same
-file handle as for stdout.
-
-If preexec_fn is set to a callable object, this object will be called
-in the child process just before the child is executed.
-
-If close_fds is true, all file descriptors except 0, 1 and 2 will be
-closed before the child process is executed.
-
-if shell is true, the specified command will be executed through the
-shell.
-
-If cwd is not None, the current directory will be changed to cwd
-before the child is executed.
-
-If env is not None, it defines the environment variables for the new
-process.
-
-If universal_newlines is true, the file objects stdout and stderr are
-opened as a text files, but lines may be terminated by any of '\n',
-the Unix end-of-line convention, '\r', the Macintosh convention or
-'\r\n', the Windows convention.  All of these external representations
-are seen as '\n' by the Python program.  Note: This feature is only
-available if Python is built with universal newline support (the
-default).  Also, the newlines attribute of the file objects stdout,
-stdin and stderr are not updated by the communicate() method.
-
-The startupinfo and creationflags, if given, will be passed to the
-underlying CreateProcess() function.  They can specify things such as
-appearance of the main window and priority for the new process.
-(Windows only)
-
-
-This module also defines some shortcut functions:
-
-call(*popenargs, **kwargs):
-    Run command with arguments.  Wait for command to complete, then
-    return the returncode attribute.
-
-    The arguments are the same as for the Popen constructor.  Example:
-
-    retcode = call(["ls", "-l"])
-
-check_call(*popenargs, **kwargs):
-    Run command with arguments.  Wait for command to complete.  If the
-    exit code was zero then return, otherwise raise
-    CalledProcessError.  The CalledProcessError object will have the
-    return code in the returncode attribute.
-
-    The arguments are the same as for the Popen constructor.  Example:
-
-    check_call(["ls", "-l"])
-
-check_output(*popenargs, **kwargs):
-    Run command with arguments and return its output as a byte string.
-
-    If the exit code was non-zero it raises a CalledProcessError.  The
-    CalledProcessError object will have the return code in the returncode
-    attribute and output in the output attribute.
-
-    The arguments are the same as for the Popen constructor.  Example:
-
-    output = check_output(["ls", "-l", "/dev/null"])
-
-
-Exceptions
-----------
-Exceptions raised in the child process, before the new program has
-started to execute, will be re-raised in the parent.  Additionally,
-the exception object will have one extra attribute called
-'child_traceback', which is a string containing traceback information
-from the child's point of view.
-
-The most common exception raised is OSError.  This occurs, for
-example, when trying to execute a non-existent file.  Applications
-should prepare for OSErrors.
-
-A ValueError will be raised if Popen is called with invalid arguments.
-
-check_call() and check_output() will raise CalledProcessError, if the
-called process returns a non-zero return code.
-
-
-Security
---------
-Unlike some other popen functions, this implementation will never call
-/bin/sh implicitly.  This means that all characters, including shell
-metacharacters, can safely be passed to child processes.
-
-
-Popen objects
-=============
-Instances of the Popen class have the following methods:
-
-poll()
-    Check if child process has terminated.  Returns returncode
-    attribute.
-
-wait()
-    Wait for child process to terminate.  Returns returncode attribute.
-
-communicate(input=None)
-    Interact with process: Send data to stdin.  Read data from stdout
-    and stderr, until end-of-file is reached.  Wait for process to
-    terminate.  The optional input argument should be a string to be
-    sent to the child process, or None, if no data should be sent to
-    the child.
-
-    communicate() returns a tuple (stdout, stderr).
-
-    Note: The data read is buffered in memory, so do not use this
-    method if the data size is large or unlimited.
-
-The following attributes are also available:
-
-stdin
-    If the stdin argument is PIPE, this attribute is a file object
-    that provides input to the child process.  Otherwise, it is None.
-
-stdout
-    If the stdout argument is PIPE, this attribute is a file object
-    that provides output from the child process.  Otherwise, it is
-    None.
-
-stderr
-    If the stderr argument is PIPE, this attribute is file object that
-    provides error output from the child process.  Otherwise, it is
-    None.
-
-pid
-    The process ID of the child process.
-
-returncode
-    The child return code.  A None value indicates that the process
-    hasn't terminated yet.  A negative value -N indicates that the
-    child was terminated by signal N (UNIX only).
-
-
-Replacing older functions with the subprocess module
-====================================================
-In this section, "a ==> b" means that b can be used as a replacement
-for a.
-
-Note: All functions in this section fail (more or less) silently if
-the executed program cannot be found; this module raises an OSError
-exception.
-
-In the following examples, we assume that the subprocess module is
-imported with "from subprocess import *".
-
-
-Replacing /bin/sh shell backquote
----------------------------------
-output=`mycmd myarg`
-==>
-output = Popen(["mycmd", "myarg"], stdout=PIPE).communicate()[0]
-
-
-Replacing shell pipe line
--------------------------
-output=`dmesg | grep hda`
-==>
-p1 = Popen(["dmesg"], stdout=PIPE)
-p2 = Popen(["grep", "hda"], stdin=p1.stdout, stdout=PIPE)
-output = p2.communicate()[0]
-
-
-Replacing os.system()
----------------------
-sts = os.system("mycmd" + " myarg")
-==>
-p = Popen("mycmd" + " myarg", shell=True)
-pid, sts = os.waitpid(p.pid, 0)
-
-Note:
-
-* Calling the program through the shell is usually not required.
-
-* It's easier to look at the returncode attribute than the
-  exitstatus.
-
-A more real-world example would look like this:
-
-try:
-    retcode = call("mycmd" + " myarg", shell=True)
-    if retcode < 0:
-        print >>sys.stderr, "Child was terminated by signal", -retcode

-Replacing os.spawn*
--------------------
-P_NOWAIT example:
-
-pid = os.spawnlp(os.P_NOWAIT, "/bin/mycmd", "mycmd", "myarg")
-==>
-pid = Popen(["/bin/mycmd", "myarg"]).pid
-
-
-P_WAIT example:
-
-retcode = os.spawnlp(os.P_WAIT, "/bin/mycmd", "mycmd", "myarg")
-==>
-retcode = call(["/bin/mycmd", "myarg"])
-
-
-Vector example:
-
-os.spawnvp(os.P_NOWAIT, path, args)
-==>
-Popen([path] + args[1:])
-
-
-Environment example:
-
-os.spawnlpe(os.P_NOWAIT, "/bin/mycmd", "mycmd", "myarg", env)
-==>
-Popen(["/bin/mycmd", "myarg"], env={"PATH": "/usr/bin"})
-
-
-Replacing os.popen*
--------------------
-pipe = os.popen("cmd", mode='r', bufsize)
-==>
-pipe = Popen("cmd", shell=True, bufsize=bufsize, stdout=PIPE).stdout
-
-pipe = os.popen("cmd", mode='w', bufsize)
-==>
-pipe = Popen("cmd", shell=True, bufsize=bufsize, stdin=PIPE).stdin
-
-
-(child_stdin, child_stdout) = os.popen2("cmd", mode, bufsize)
-==>
-p = Popen("cmd", shell=True, bufsize=bufsize,
-          stdin=PIPE, stdout=PIPE, close_fds=True)
-(child_stdin, child_stdout) = (p.stdin, p.stdout)
-
-
-(child_stdin,
- child_stdout,
- child_stderr) = os.popen3("cmd", mode, bufsize)
-==>
-p = Popen("cmd", shell=True, bufsize=bufsize,
-          stdin=PIPE, stdout=PIPE, stderr=PIPE, close_fds=True)
-(child_stdin,
- child_stdout,
- child_stderr) = (p.stdin, p.stdout, p.stderr)
-
-
-(child_stdin, child_stdout_and_stderr) = os.popen4("cmd", mode,
-                                                   bufsize)
-==>
-p = Popen("cmd", shell=True, bufsize=bufsize,
-          stdin=PIPE, stdout=PIPE, stderr=STDOUT, close_fds=True)
-(child_stdin, child_stdout_and_stderr) = (p.stdin, p.stdout)
-
-On Unix, os.popen2, os.popen3 and os.popen4 also accept a sequence as
-the command to execute, in which case arguments will be passed
-directly to the program without shell intervention.  This usage can be
-replaced as follows:
-
-(child_stdin, child_stdout) = os.popen2(["/bin/ls", "-l"], mode,
-                                        bufsize)
-==>
-p = Popen(["/bin/ls", "-l"], bufsize=bufsize, stdin=PIPE, stdout=PIPE)
-(child_stdin, child_stdout) = (p.stdin, p.stdout)
-
-Return code handling translates as follows:
-
-pipe = os.popen("cmd", 'w')
-...
-rc = pipe.close()
-if rc is not None and rc % 256:
-    print "There were some errors"
-==>
-process = Popen("cmd", 'w', shell=True, stdin=PIPE)
-...
-process.stdin.close()
-if process.wait() != 0:
-    print "There were some errors"
-
-
-Replacing popen2.*
-------------------
-(child_stdout, child_stdin) = popen2.popen2("somestring", bufsize, mode)
-==>
-p = Popen(["somestring"], shell=True, bufsize=bufsize
-          stdin=PIPE, stdout=PIPE, close_fds=True)
-(child_stdout, child_stdin) = (p.stdout, p.stdin)
-
-On Unix, popen2 also accepts a sequence as the command to execute, in
-which case arguments will be passed directly to the program without
-shell intervention.  This usage can be replaced as follows:
-
-(child_stdout, child_stdin) = popen2.popen2(["mycmd", "myarg"], bufsize,
-                                            mode)
-==>
-p = Popen(["mycmd", "myarg"], bufsize=bufsize,
-          stdin=PIPE, stdout=PIPE, close_fds=True)
-(child_stdout, child_stdin) = (p.stdout, p.stdin)
-
-The popen2.Popen3 and popen2.Popen4 basically works as subprocess.Popen,
-except that:
-
-* subprocess.Popen raises an exception if the execution fails
-* the capturestderr argument is replaced with the stderr argument.
-* stdin=PIPE and stdout=PIPE must be specified.
-* popen2 closes all filedescriptors by default, but you have to specify
-  close_fds=True with subprocess.Popen.

-r"""TELNET client class.
-
-Based on RFC 854: TELNET Protocol Specification, by J. Postel and
-J. Reynolds
-
-Example:
-
->>> from telnetlib import Telnet
->>> tn = Telnet('www.python.org', 79)   # connect to finger port
->>> tn.write('guido\r\n')
->>> print tn.read_all()

-guido    Guido van Rossum      pts/2        <Dec  2 11:10> snag.cnri.reston..
-
->>>
-
-Note that read_all() won't read until eof -- it just reads some data
--- but it guarantees to read at least one byte unless EOF is hit.
-
-It is possible to pass a Telnet object to select.select() in order to
-wait until more data is available.  Note that in this case,
-read_eager() may return '' even if there was data on the socket,
-because the protocol negotiation may have eaten the data.  This is why
-EOFError is needed in some cases to distinguish between "no data" and
-"connection closed" (since the socket also appears ready for reading
-when it is closed).
-
-To do:
-- option negotiation
-- timeout should be intrinsic to the connection object instead of an
-  option on one of the read calls only

-class Telnet:
-
-    """Telnet interface class.
-
-    An instance of this class represents a connection to a telnet
-    server.  The instance is initially not connected; the open()
-    method must be used to establish a connection.  Alternatively, the
-    host name and optional port number can be passed to the
-    constructor, too.
-
-    Don't try to reopen an already connected instance.
-
-    This class has many read_*() methods.  Note that some of them
-    raise EOFError when the end of the connection is read, because
-    they can return an empty string for other reasons.  See the
-    individual doc strings.
-
-    read_until(expected, [timeout])
-        Read until the expected string has been seen, or a timeout is
-        hit (default is no timeout); may block.
-
-    read_all()
-        Read all data until EOF; may block.
-
-    read_some()
-        Read at least one byte or EOF; may block.
-
-    read_very_eager()
-        Read all data available already queued or on the socket,
-        without blocking.
-
-    read_eager()
-        Read either data already queued or some data available on the
-        socket, without blocking.
-
-    read_lazy()
-        Read all data in the raw queue (processing it first), without
-        doing any socket I/O.
-
-    read_very_lazy()
-        Reads all data in the cooked queue, without doing any socket
-        I/O.
-
-    read_sb_data()
-        Reads available data between SB ... SE sequence. Don't block.
-
-    set_option_negotiation_callback(callback)
-        Each time a telnet option is read on the input flow, this callback
-        (if set) is called with the following parameters :
-        callback(telnet socket, command, option)
-            option will be chr(0) when there is no option.
-        No other action is done afterwards by telnetlib.

-generate_tokens(readline) is a generator that breaks a stream of
-text into Python tokens.  It accepts a readline-like method which is called
-repeatedly to get the next line of input (or "" for EOF).  It generates
-5-tuples with these members:
-
-    the token type (see token.py)
-    the token (a string)
-    the starting (row, column) indices of the token (a 2-tuple of ints)
-    the ending (row, column) indices of the token (a 2-tuple of ints)
-    the original line (string)
-
-It is designed to match the working of the Python tokenizer exactly, except
-that it produces COMMENT tokens for comments and gives type OP for all
-operators
-
-Older entry points
-    tokenize_loop(readline, tokeneater)
-    tokenize(readline, tokeneater=printtoken)
-are the same, except instead of generating tokens, tokeneater is a callback
-function to which the 5 fields described above are passed as 5 arguments,
-each time a new token is found."""

-"""An extensible library for opening URLs using a variety of protocols
-
-The simplest way to use this module is to call the urlopen function,
-which accepts a string containing a URL or a Request object (described
-below).  It opens the URL and returns the results as file-like
-object; the returned object has some extra methods described below.
-
-The OpenerDirector manages a collection of Handler objects that do
-all the actual work.  Each Handler implements a particular protocol or
-option.  The OpenerDirector is a composite object that invokes the
-Handlers needed to open the requested URL.  For example, the
-HTTPHandler performs HTTP GET and POST requests and deals with
-non-error returns.  The HTTPRedirectHandler automatically deals with
-HTTP 301, 302, 303 and 307 redirect errors, and the HTTPDigestAuthHandler
-deals with digest authentication.
-
-urlopen(url, data=None) -- Basic usage is the same as original
-urllib.  pass the url and optionally data to post to an HTTP URL, and
-get a file-like object back.  One difference is that you can also pass
-a Request instance instead of URL.  Raises a URLError (subclass of
-IOError); for HTTP errors, raises an HTTPError, which can also be
-treated as a valid response.
-
-build_opener -- Function that creates a new OpenerDirector instance.
-Will install the default handlers.  Accepts one or more Handlers as
-arguments, either instances or Handler classes that it will
-instantiate.  If one of the argument is a subclass of the default
-handler, the argument will be installed instead of the default.
-
-install_opener -- Installs a new opener as the default opener.
-
-objects of interest:
-
-OpenerDirector -- Sets up the User Agent as the Python-urllib client and manages
-the Handler classes, while dealing with requests and responses.
-
-Request -- An object that encapsulates the state of a request.  The
-state can be as simple as the URL.  It can also include extra HTTP
-headers, e.g. a User-Agent.
-
-BaseHandler --
-
-exceptions:
-URLError -- A subclass of IOError, individual protocols have their own
-specific subclass.
-
-HTTPError -- Also a valid HTTP response, so you can treat an HTTP error
-as an exceptional event or valid response.
-
-internals:
-BaseHandler and parent
-_call_chain conventions
-
-Example usage:
-
-import urllib2
-
-# set up authentication info
-authinfo = urllib2.HTTPBasicAuthHandler()
-authinfo.add_password(realm='PDQ Application',
-                      uri='https://mahler:8092/site-updates.py',
-                      user='klem',
-                      passwd='geheim$parole')
-
-proxy_support = urllib2.ProxyHandler({"http" : "http://ahad-haam:3128"})
-
-# build a new opener that adds authentication and caching FTP handlers
-opener = urllib2.build_opener(proxy_support, authinfo, urllib2.CacheFTPHandler)
-
-# install it
-urllib2.install_opener(opener)
-
-f = urllib2.urlopen('http://www.python.org/')
-
-
-"""
-
-# XXX issues:
-# If an authentication error handler that tries to perform
-# authentication for some reason but fails, how should the error be
-# signalled?  The client needs to know the HTTP error code.  But if
-# the handler knows that the problem was, e.g., that it didn't know
-# that hash algo that requested in the challenge, it would be good to
-# pass that information along to the client, too.
-# ftp errors aren't handled cleanly
-# check digest against correct (i.e. non-apache) implementation
-
-# Possible extensions:
-# complex proxies  XXX not sure what exactly was meant by this
-# abstract factory for opener

-1995.
-
-RFC 1738: "Uniform Resource Locators (URL)" by T. Berners-Lee, L. Masinter, M.
-McCahill, December 1994
-
-RFC 3986 is considered the current standard and any future changes to
-urlparse module should conform with it.  The urlparse module is
-currently not entirely compliant with this RFC due to defacto
-scenarios for parsing, and for backward compatibility purposes, some
-parsing quirks from older RFCs are retained. The testcases in
-test_urlparse.py provides a good indicator of parsing behavior.

-This module provides immutable UUID objects (class UUID) and the functions
-uuid1(), uuid3(), uuid4(), uuid5() for generating version 1, 3, 4, and 5
-UUIDs as specified in RFC 4122.
-
-If all you want is a unique ID, you should probably call uuid1() or uuid4().
-Note that uuid1() may compromise privacy since it creates a UUID containing
-the computer's network address.  uuid4() creates a random UUID.

-
-    >>> import uuid

-    # make a UUID based on the host ID and current time
-    >>> uuid.uuid1()
-    UUID('a8098c1a-f86e-11da-bd1a-00112444be1e')
-
-    # make a UUID using an MD5 hash of a namespace UUID and a name

-    UUID('6fa459ea-ee8a-3ca4-894e-db77e160355e')
-
-    # make a random UUID
-    >>> uuid.uuid4()
-    UUID('16fd2706-8baf-433b-82eb-8c7fada847da')

-    # make a UUID using a SHA-1 hash of a namespace UUID and a name

-    UUID('886313e1-3b8a-5372-9b90-0c9aee199e5d')
-
-    # make a UUID from a string of hex digits (braces and hyphens ignored)
-    >>> x = uuid.UUID('{00010203-0405-0607-0809-0a0b0c0d0e0f}')

-# The <b>Element</b> type is a flexible container object, designed to
-# store hierarchical data structures in memory. The type can be
-# described as a cross between a list and a dictionary.
-# <p>
-# Each element has a number of properties associated with it:
-# <ul>
-# <li>a <i>tag</i>. This is a string identifying what kind of data
-# this element represents (the element type, in other words).</li>
-# <li>a number of <i>attributes</i>, stored in a Python dictionary.</li>
-# <li>a <i>text</i> string.</li>
-# <li>an optional <i>tail</i> string.</li>
-# <li>a number of <i>child elements</i>, stored in a Python sequence</li>
-# </ul>
-#
-# To create an element instance, use the {@link #Element} constructor
-# or the {@link #SubElement} factory function.
-# <p>
-# The {@link #ElementTree} class can be used to wrap an element
-# structure, and convert it from and to XML.

-# XML-RPC CLIENT LIBRARY
-# $Id$
-#
-# an XML-RPC client interface for Python.
-#
-# the marshalling and response parser code can also be used to
-# implement XML-RPC servers.
-#
-# Notes:
-# this version is designed to work with Python 2.1 or newer.
-#
-# History:
-# 1999-01-14 fl  Created
-# 1999-01-15 fl  Changed dateTime to use localtime
-# 1999-01-16 fl  Added Binary/base64 element, default to RPC2 service
-# 1999-01-19 fl  Fixed array data element (from Skip Montanaro)
-# 1999-01-21 fl  Fixed dateTime constructor, etc.
-# 1999-02-02 fl  Added fault handling, handle empty sequences, etc.
-# 1999-02-10 fl  Fixed problem with empty responses (from Skip Montanaro)
-# 1999-06-20 fl  Speed improvements, pluggable parsers/transports (0.9.8)
-# 2000-11-28 fl  Changed boolean to check the truth value of its argument
-# 2001-02-24 fl  Added encoding/Unicode/SafeTransport patches
-# 2001-02-26 fl  Added compare support to wrappers (0.9.9/1.0b1)
-# 2001-03-28 fl  Make sure response tuple is a singleton
-# 2001-03-29 fl  Don't require empty params element (from Nicholas Riley)
-# 2001-06-10 fl  Folded in _xmlrpclib accelerator support (1.0b2)
-# 2001-08-20 fl  Base xmlrpclib.Error on built-in Exception (from Paul Prescod)
-# 2001-09-03 fl  Allow Transport subclass to override getparser
-# 2001-09-10 fl  Lazy import of urllib, cgi, xmllib (20x import speedup)
-# 2001-10-01 fl  Remove containers from memo cache when done with them
-# 2001-10-01 fl  Use faster escape method (80% dumps speedup)
-# 2001-10-02 fl  More dumps microtuning
-# 2001-10-04 fl  Make sure import expat gets a parser (from Guido van Rossum)
-# 2001-10-10 sm  Allow long ints to be passed as ints if they don't overflow
-# 2001-10-17 sm  Test for int and long overflow (allows use on 64-bit systems)
-# 2001-11-12 fl  Use repr() to marshal doubles (from Paul Felix)
-# 2002-03-17 fl  Avoid buffered read when possible (from James Rucker)

+A. HISTORY OF THE SOFTWARE
+==========================
+
+Python was created in the early 1990s by Guido van Rossum at Stichting
+Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
+as a successor of a language called ABC.  Guido remains Python's
+principal author, although it includes many contributions from others.
+
+In 1995, Guido continued his work on Python at the Corporation for
+National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
+in Reston, Virginia where he released several versions of the
+software.
+
+In May 2000, Guido and the Python core development team moved to
+BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
+year, the PythonLabs team moved to Digital Creations (now Zope
+Corporation, see http://www.zope.com).  In 2001, the Python Software
+Foundation (PSF, see http://www.python.org/psf/) was formed, a
+non-profit organization created specifically to own Python-related
+Intellectual Property.  Zope Corporation is a sponsoring member of
+the PSF.
+
+All Python releases are Open Source (see http://www.opensource.org for
+the Open Source Definition).  Historically, most, but not all, Python
+releases have also been GPL-compatible; the table below summarizes
+the various releases.
+
+    Release         Derived     Year        Owner       GPL-
+                    from                                compatible? (1)

+
+Footnotes:
+
+(1) GPL-compatible doesn't mean that we're distributing Python under
+    the GPL.  All Python licenses, unlike the GPL, let you distribute
+    a modified version without making your changes open source.  The
+    GPL-compatible licenses make it possible to combine Python with
+    other software that is released under the GPL; the others don't.
+
+(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
+    because its license has a choice of law clause.  According to
+    CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
+    is "not incompatible" with the GPL.
+
+Thanks to the many outside volunteers who have worked under Guido's
+direction to make these releases possible.

+"""Thread-local objects.
+
+(Note that this module provides a Python version of the threading.local
+ class.  Depending on the version of Python you're using, there may be a
+ faster one available.  You should always import the `local` class from
+ `threading`.)
+
+Thread-local objects support the management of thread-local data.
+If you have data that you want to be local to a thread, simply create
+a thread-local object and use its attributes:
+
+  >>> mydata = local()
+  >>> mydata.number = 42
+  >>> mydata.number
+  42
+
+You can also access the local-object's dictionary:
+
+  >>> mydata.__dict__
+  {'number': 42}
+  >>> mydata.__dict__.setdefault('widgets', [])
+  []
+  >>> mydata.widgets
+  []
+
+What's important about thread-local objects is that their data are
+local to a thread. If we access the data in a different thread:
+
+  >>> log = []
+  >>> def f():
+  ...     items = sorted(mydata.__dict__.items())
+  ...     log.append(items)
+  ...     mydata.number = 11
+  ...     log.append(mydata.number)
+
+  >>> import threading
+  >>> thread = threading.Thread(target=f)
+  >>> thread.start()
+  >>> thread.join()
+  >>> log
+  [[], 11]
+
+we get different data.  Furthermore, changes made in the other thread
+don't affect data seen in this thread:
+
+  >>> mydata.number
+  42
+
+Of course, values you get from a local object, including a __dict__
+attribute, are for whatever thread was current at the time the
+attribute was read.  For that reason, you generally don't want to save
+these values across threads, as they apply only to the thread they
+came from.
+
+You can create custom local objects by subclassing the local class:
+
+  >>> class MyLocal(local):
+  ...     number = 2
+  ...     initialized = False
+  ...     def __init__(self, **kw):
+  ...         if self.initialized:
+  ...             raise SystemError('__init__ called too many times')
+  ...         self.initialized = True
+  ...         self.__dict__.update(kw)
+  ...     def squared(self):
+  ...         return self.number ** 2
+
+This can be useful to support default values, methods and
+initialization.  Note that if you define an __init__ method, it will be
+called each time the local object is used in a separate thread.  This
+is necessary to initialize each thread's dictionary.
+
+Now if we create a local object:
+
+  >>> mydata = MyLocal(color='red')
+
+Now we have a default number:
+
+  >>> mydata.number
+  2
+
+an initial color:
+
+  >>> mydata.color
+  'red'
+  >>> del mydata.color
+
+And a method that operates on the data:
+
+  >>> mydata.squared()
+  4
+
+As before, we can access the data in a separate thread:
+
+  >>> log = []
+  >>> thread = threading.Thread(target=f)
+  >>> thread.start()
+  >>> thread.join()
+  >>> log
+  [[('color', 'red'), ('initialized', True)], 11]
+
+without affecting this thread's data:
+
+  >>> mydata.number
+  2
+  >>> mydata.color
+  Traceback (most recent call last):
+  ...
+  AttributeError: 'MyLocal' object has no attribute 'color'
+
+Note that subclasses can define slots, but they are not thread
+local. They are shared across threads:
+
+  >>> class MyLocal(local):
+  ...     __slots__ = 'number'
+
+  >>> mydata = MyLocal()
+  >>> mydata.number = 42
+  >>> mydata.color = 'red'
+
+So, the separate thread:
+
+  >>> thread = threading.Thread(target=f)
+  >>> thread.start()
+  >>> thread.join()
+
+affects what we see:
+
+  >>> mydata.number
+  11
+
+>>> del mydata

+"""Stuff to parse AIFF-C and AIFF files.
+
+Unless explicitly stated otherwise, the description below is true
+both for AIFF-C files and AIFF files.
+
+An AIFF-C file has the following structure.
+
+  +-----------------+
+  | FORM            |
+  +-----------------+
+  | <size>          |
+  +----+------------+
+  |    | AIFC       |
+  |    +------------+
+  |    | <chunks>   |
+  |    |    .       |
+  |    |    .       |
+  |    |    .       |
+  +----+------------+
+
+An AIFF file has the string "AIFF" instead of "AIFC".
+
+A chunk consists of an identifier (4 bytes) followed by a size (4 bytes,
+big endian order), followed by the data.  The size field does not include
+the size of the 8 byte header.
+
+The following chunk types are recognized.
+
+  FVER
+      <version number of AIFF-C defining document> (AIFF-C only).
+  MARK
+      <# of markers> (2 bytes)
+      list of markers:
+          <marker ID> (2 bytes, must be > 0)
+          <position> (4 bytes)
+          <marker name> ("pstring")
+  COMM
+      <# of channels> (2 bytes)
+      <# of sound frames> (4 bytes)
+      <size of the samples> (2 bytes)
+      <sampling frequency> (10 bytes, IEEE 80-bit extended
+          floating point)
+      in AIFF-C files only:
+      <compression type> (4 bytes)
+      <human-readable version of compression type> ("pstring")
+  SSND
+      <offset> (4 bytes, not used by this program)
+      <blocksize> (4 bytes, not used by this program)
+      <sound data>
+
+A pstring consists of 1 byte length, a string of characters, and 0 or 1
+byte pad to make the total length even.
+
+Usage.
+
+Reading AIFF files:
+  f = aifc.open(file, 'r')
+where file is either the name of a file or an open file pointer.
+The open file pointer must have methods read(), seek(), and close().
+In some types of audio files, if the setpos() method is not used,
+the seek() method is not necessary.
+
+This returns an instance of a class with the following public methods:
+  getnchannels()  -- returns number of audio channels (1 for
+             mono, 2 for stereo)
+  getsampwidth()  -- returns sample width in bytes
+  getframerate()  -- returns sampling frequency
+  getnframes()    -- returns number of audio frames
+  getcomptype()   -- returns compression type ('NONE' for AIFF files)
+  getcompname()   -- returns human-readable version of
+             compression type ('not compressed' for AIFF files)
+  getparams() -- returns a namedtuple consisting of all of the
+             above in the above order
+  getmarkers()    -- get the list of marks in the audio file or None
+             if there are no marks
+  getmark(id) -- get mark with the specified id (raises an error
+             if the mark does not exist)
+  readframes(n)   -- returns at most n frames of audio
+  rewind()    -- rewind to the beginning of the audio stream
+  setpos(pos) -- seek to the specified position
+  tell()      -- return the current position
+  close()     -- close the instance (make it unusable)
+The position returned by tell(), the position given to setpos() and
+the position of marks are all compatible and have nothing to do with
+the actual position in the file.
+The close() method is called automatically when the class instance
+is destroyed.
+
+Writing AIFF files:
+  f = aifc.open(file, 'w')
+where file is either the name of a file or an open file pointer.
+The open file pointer must have methods write(), tell(), seek(), and
+close().
+
+This returns an instance of a class with the following public methods:
+  aiff()      -- create an AIFF file (AIFF-C default)
+  aifc()      -- create an AIFF-C file
+  setnchannels(n) -- set the number of channels
+  setsampwidth(n) -- set the sample width
+  setframerate(n) -- set the frame rate
+  setnframes(n)   -- set the number of frames
+  setcomptype(type, name)
+          -- set the compression type and the
+             human-readable compression type
+  setparams(tuple)
+          -- set all parameters at once
+  setmark(id, pos, name)
+          -- add specified mark to the list of marks
+  tell()      -- return current position in output file (useful
+             in combination with setmark())
+  writeframesraw(data)
+          -- write audio frames without pathing up the
+             file header
+  writeframes(data)
+          -- write audio frames and patch up the file header
+  close()     -- patch up the file header and close the
+             output file
+You should set the parameters before the first writeframesraw or
+writeframes.  The total number of frames does not need to be set,
+but when it is set to the correct value, the header does not have to
+be patched up.
+It is best to first set all parameters, perhaps possibly the
+compression type, and then write audio frames using writeframesraw.
+When all frames have been written, either call writeframes('') or
+close() to patch up the sizes in the header.
+Marks can be added anytime.  If there are any marks, you must call
+close() after all frames have been written.
+The close() method is called automatically when the class instance
+is destroyed.
+
+When a file is opened with the extension '.aiff', an AIFF file is
+written, otherwise an AIFF-C file is written.  This default can be
+changed by calling aiff() or aifc() before the first writeframes or
+writeframesraw.

+"""
+    ast
+    ~~~
+
+    The `ast` module helps Python applications to process trees of the Python
+    abstract syntax grammar.  The abstract syntax itself might change with
+    each Python release; this module helps to find out programmatically what
+    the current grammar looks like and allows modifications of it.
+
+    An abstract syntax tree can be generated by passing `ast.PyCF_ONLY_AST` as
+    a flag to the `compile()` builtin function or by using the `parse()`
+    function from this module.  The result will be a tree of objects whose
+    classes all inherit from `ast.AST`.
+
+    A modified abstract syntax tree can be compiled into a Python code object
+    using the built-in `compile()` function.
+
+    Additionally various helper functions are provided that make working with
+    the trees simpler.  The main intention of the helper functions and this
+    module in general is to provide an easy to use interface for libraries
+    that work tightly with the python syntax (template engines for example).

+    The `NodeTransformer` will walk the AST and use the return value of the

+    the visitor method is ``None``, the node will be removed from its location,
+    otherwise it is replaced with the return value.  The return value may be the
+    original node in which case no replacement takes place.

+
+    Keep in mind that if the node you're operating on has child nodes you must
+    either transform the child nodes yourself or call the :meth:`generic_visit`
+    method for the node first.
+
+    For nodes that were part of a collection of statements (that applies to all
+    statement nodes), the visitor may also return a list of nodes rather than
+    just a single node.

+
+    This solves a nasty problem with Futures and Tasks that have an
+    exception set: if nobody asks for the exception, the exception is
+    never logged.  This violates the Zen of Python: 'Errors should
+    never pass silently.  Unless explicitly silenced.'
+
+    However, we don't want to log the exception as soon as
+    set_exception() is called: if the calling code is written
+    properly, it will get the exception and handle it properly.  But
+    we *do* want to log it if result() or exception() was never called
+    -- otherwise developers waste a lot of time wondering why their
+    buggy code fails silently.
+
+    An earlier attempt added a __del__() method to the Future class
+    itself, but this backfired because the presence of __del__()
+    prevents garbage collection from breaking cycles.  A way out of
+    this catch-22 is to avoid having a __del__() method on the Future
+    class itself, but instead to have a reference to a helper object
+    with a __del__() method that logs the traceback, where we ensure
+    that the helper object doesn't participate in cycles, and only the
+    Future has a reference to it.
+
+    The helper object is added when set_exception() is called.  When
+    the Future is collected, and the helper is present, the helper
+    object is also collected, and its __del__() method will log the
+    traceback.  When the Future's result() or exception() method is
+    called (and a helper object is present), it removes the the helper
+    object, after calling its clear() method to prevent it from
+    logging.
+
+    One downside is that we do a fair amount of work to extract the
+    traceback from the exception, even when it is never logged.  It
+    would seem cheaper to just store the exception object, but that
+    references the traceback, which references stack frames, which may
+    reference the Future, which references the _TracebackLogger, and
+    then the _TracebackLogger would be included in a cycle, which is
+    what we're trying to avoid!  As an optimization, we don't
+    immediately format the exception; we only do the work when
+    activate() is called, which call is delayed until after all the
+    Future's callbacks have run.  Since usually a Future has at least
+    one callback (typically set by 'yield from') and usually that
+    callback extracts the callback, thereby removing the need to
+    format the exception.
+
+    PS. I don't claim credit for this solution.  I first heard of it

+
+    A primitive lock is a synchronization primitive that is not owned

+
+    It is created in the unlocked state.  It has two basic methods,
+    acquire() and release().  When the state is unlocked, acquire()
+    changes the state to locked and returns immediately.  When the
+    state is locked, acquire() blocks until a call to release() in
+    another coroutine changes it to unlocked, then the acquire() call
+    resets it to locked and returns.  The release() method should only
+    be called in the locked state; it changes the state to unlocked
+    and returns immediately.  If an attempt is made to release an
+    unlocked lock, a RuntimeError will be raised.
+
+    When more than one coroutine is blocked in acquire() waiting for
+    the state to turn to unlocked, only one coroutine proceeds when a
+    release() call resets the state to unlocked; first coroutine which
+    is blocked in acquire() is being processed.

+    The items are either a Python list (if there's multiple values) or
+    another FieldStorage or MiniFieldStorage object.  If it's a single
+    object, it has the following attributes:
+
+    name: the field name, if specified; otherwise None
+
+    filename: the filename, if specified; otherwise None; this is the
+        client side filename, *not* the file name on which it is
+        stored (that's a temporary file you don't deal with)
+
+    value: the value as a *string*; for file uploads, this
+        transparently reads the file every time you request the value
+        and returns *bytes*
+
+    file: the file(-like) object from which you can read the data *as
+        bytes* ; None if the data is stored a simple string
+
+    type: the content-type, or None if not specified
+
+    type_options: dictionary of options specified on the content-type
+        line
+
+    disposition: content-disposition, or None if not specified
+
+    disposition_options: dictionary of corresponding options
+
+    headers: a dictionary(-like) object (sometimes email.message.Message or a
+        subclass thereof) containing *all* headers
+
+    The class is subclassable, mostly for the purpose of overriding
+    the make_file() method, which is called internally to come up with
+    a file open for reading and writing.  This makes it possible to
+    override the default choice of storing all files in a temporary

+"""A generic class to build line-oriented command interpreters.
+
+Interpreters constructed with this class obey the following conventions:
+
+1. End of file on input is processed as the command 'EOF'.
+2. A command is parsed out of each line by collecting the prefix composed
+   of characters in the identchars member.
+3. A command `foo' is dispatched to a method 'do_foo()'; the do_ method
+   is passed a single argument consisting of the remainder of the line.
+4. Typing an empty line repeats the last command.  (Actually, it calls the
+   method `emptyline', which may be overridden in a subclass.)
+5. There is a predefined `help' method.  Given an argument `topic', it
+   calls the command `help_topic'.  With no arguments, it lists all topics
+   with defined help_ functions, broken into up to three topics; documented
+   commands, miscellaneous help topics, and undocumented commands.
+6. The command '?' is a synonym for `help'.  The command '!' is a synonym
+   for `shell', if a do_shell method exists.
+7. If completion is enabled, completing commands will be done automatically,
+   and completing of commands args is done by calling complete_foo() with
+   arguments text, line, begidx, endidx.  text is string we are matching
+   against, all returned matches must begin with it.  line is the current
+   input line (lstripped), begidx and endidx are the beginning and end
+   indexes of the text being matched, which could be used to provide
+   different completion depending upon which position the argument is in.
+
+The `default' method may be overridden to intercept commands for which there
+is no do_ method.
+
+The `completedefault' method may be overridden to intercept completions for
+commands that have no complete_ method.
+
+The data member `self.ruler' sets the character used to draw separator lines
+in the help messages.  If empty, no ruler line is drawn.  It defaults to "=".
+
+If the value of `self.intro' is nonempty when the cmdloop method is called,
+it is printed out on interpreter startup.  This value may be overridden
+via an optional argument to the cmdloop() method.
+
+The data members `self.doc_header', `self.misc_header', and
+`self.undoc_header' set the headers used for the help function's
+listings of documented functions, miscellaneous topics, and undocumented
+functions respectively.

+# -*- makefile -*-
+# The file Setup is used by the makesetup script to construct the files
+# Makefile and config.c, from Makefile.pre and config.c.in,
+# respectively.  The file Setup itself is initially copied from
+# Setup.dist; once it exists it will not be overwritten, so you can edit
+# Setup to your heart's content.  Note that Makefile.pre is created
+# from Makefile.pre.in by the toplevel configure script.
+
+# (VPATH notes: Setup and Makefile.pre are in the build directory, as
+# are Makefile and config.c; the *.in and *.dist files are in the source
+# directory.)
+
+# Each line in this file describes one or more optional modules.
+# Modules enabled here will not be compiled by the setup.py script,
+# so the file can be used to override setup.py's behavior.
+
+# Lines have the following structure:
+#
+# <module> ... [<sourcefile> ...] [<cpparg> ...] [<library> ...]
+#
+# <sourcefile> is anything ending in .c (.C, .cc, .c++ are C++ files)
+# <cpparg> is anything starting with -I, -D, -U or -C
+# <library> is anything ending in .a or beginning with -l or -L
+# <module> is anything else but should be a valid Python
+# identifier (letters, digits, underscores, beginning with non-digit)
+#
+# (As the makesetup script changes, it may recognize some other
+# arguments as well, e.g. *.so and *.sl as libraries.  See the big
+# case statement in the makesetup script.)
+#
+# Lines can also have the form
+#
+# <name> = <value>
+#
+# which defines a Make variable definition inserted into Makefile.in
+#
+# Finally, if a line contains just the word "*shared*" (without the
+# quotes but with the stars), then the following modules will not be
+# built statically.  The build process works like this:
+#
+# 1. Build all modules that are declared as static in Modules/Setup,
+#    combine them into libpythonxy.a, combine that into python.
+# 2. Build all modules that are listed as shared in Modules/Setup.
+# 3. Invoke setup.py. That builds all modules that
+#    a) are not builtin, and
+#    b) are not listed in Modules/Setup, and
+#    c) can be build on the target
+#
+# Therefore, modules declared to be shared will not be
+# included in the config.c file, nor in the list of objects to be
+# added to the library archive, and their linker options won't be
+# added to the linker options. Rules to create their .o files and
+# their shared libraries will still be added to the Makefile, and
+# their names will be collected in the Make variable SHAREDMODS.  This
+# is used to build modules as shared libraries.  (They can be
+# installed using "make sharedinstall", which is implied by the
+# toplevel "make install" target.)  (For compatibility,
+# *noconfig* has the same effect as *shared*.)
+#
+# In addition, *static* explicitly declares the following modules to
+# be static.  Lines containing "*static*" and "*shared*" may thus
+# alternate throughout this file.
+
+# NOTE: As a standard policy, as many modules as can be supported by a
+# platform should be present.  The distribution comes with all modules
+# enabled that are supported by most platforms and don't require you
+# to ftp sources from elsewhere.
+

+# Edit the definitions below to indicate which options you are using.

+"""Configuration file parser.
+
+A configuration file consists of sections, lead by a "[section]" header,
+and followed by "name: value" entries, with continuations and such in
+the style of RFC 822.
+
+Intrinsic defaults can be specified by passing them into the
+ConfigParser constructor as a dictionary.
+
+class:
+
+ConfigParser -- responsible for parsing a list of
+                    configuration files, and managing the parsed database.
+
+    methods:
+
+    __init__(defaults=None, dict_type=_default_dict, allow_no_value=False,
+             delimiters=('=', ':'), comment_prefixes=('#', ';'),
+             inline_comment_prefixes=None, strict=True,
+             empty_lines_in_values=True):
+        Create the parser. When `defaults' is given, it is initialized into the
+        dictionary or intrinsic defaults. The keys must be strings, the values
+        must be appropriate for %()s string interpolation.
+
+        When `dict_type' is given, it will be used to create the dictionary
+        objects for the list of sections, for the options within a section, and
+        for the default values.
+
+        When `delimiters' is given, it will be used as the set of substrings
+        that divide keys from values.
+
+        When `comment_prefixes' is given, it will be used as the set of
+        substrings that prefix comments in empty lines. Comments can be
+        indented.
+
+        When `inline_comment_prefixes' is given, it will be used as the set of
+        substrings that prefix comments in non-empty lines.
+
+        When `strict` is True, the parser won't allow for any section or option
+        duplicates while reading from a single source (file, string or
+        dictionary). Default is True.
+
+        When `empty_lines_in_values' is False (default: True), each empty line
+        marks the end of an option. Otherwise, internal empty lines of
+        a multiline option are kept as part of the value.
+
+        When `allow_no_value' is True (default: False), options without
+        values are accepted; the value presented for these is None.
+
+    sections()
+        Return all the configuration section names, sans DEFAULT.
+
+    has_section(section)
+        Return whether the given section exists.
+
+    has_option(section, option)
+        Return whether the given option exists in the given section.
+
+    options(section)
+        Return list of configuration options for the named section.
+
+    read(filenames, encoding=None)
+        Read and parse the list of named configuration files, given by
+        name.  A single filename is also allowed.  Non-existing files
+        are ignored.  Return list of successfully read files.
+
+    read_file(f, filename=None)
+        Read and parse one configuration file, given as a file object.
+        The filename defaults to f.name; it is only used in error
+        messages (if f has no `name' attribute, the string `<???>' is used).
+
+    read_string(string)
+        Read configuration from a given string.
+
+    read_dict(dictionary)
+        Read configuration from a dictionary. Keys are section names,
+        values are dictionaries with keys and values that should be present
+        in the section. If the used dictionary type preserves order, sections
+        and their keys will be added in order. Values are automatically
+        converted to strings.
+
+    get(section, option, raw=False, vars=None, fallback=_UNSET)
+        Return a string value for the named option.  All % interpolations are
+        expanded in the return values, based on the defaults passed into the
+        constructor and the DEFAULT section.  Additional substitutions may be
+        provided using the `vars' argument, which must be a dictionary whose
+        contents override any pre-existing defaults. If `option' is a key in
+        `vars', the value from `vars' is used.
+
+    getint(section, options, raw=False, vars=None, fallback=_UNSET)
+        Like get(), but convert value to an integer.
+
+    getfloat(section, options, raw=False, vars=None, fallback=_UNSET)
+        Like get(), but convert value to a float.
+
+    getboolean(section, options, raw=False, vars=None, fallback=_UNSET)
+        Like get(), but convert value to a boolean (currently case
+        insensitively defined as 0, false, no, off for False, and 1, true,
+        yes, on for True).  Returns False or True.
+
+    items(section=_UNSET, raw=False, vars=None)
+        If section is given, return a list of tuples with (name, value) for
+        each option in the section. Otherwise, return a list of tuples with
+        (section_name, section_proxy) for each section, including DEFAULTSECT.
+
+    remove_section(section)
+        Remove the given file section and all its options.
+
+    remove_option(section, option)
+        Remove the given option from the given section.
+
+    set(section, option, value)
+        Set the given option.
+
+    write(fp, space_around_delimiters=True)
+        Write the configuration state in .ini format. If
+        `space_around_delimiters' is True (the default), delimiters
+        between keys and values are surrounded by spaces.

+"""Generic (shallow and deep) copying operations.
+
+Interface summary:
+
+        import copy
+
+        x = copy.copy(y)        # make a shallow copy of y
+        x = copy.deepcopy(y)    # make a deep copy of y
+
+For module specific errors, copy.Error is raised.
+
+The difference between shallow and deep copying is only relevant for
+compound objects (objects that contain other objects, like lists or
+class instances).
+
+- A shallow copy constructs a new compound object and then (to the
+  extent possible) inserts *the same objects* into it that the
+  original contains.
+
+- A deep copy constructs a new compound object and then, recursively,
+  inserts *copies* into it of the objects found in the original.
+
+Two problems often exist with deep copy operations that don't exist
+with shallow copy operations:
+
+ a) recursive objects (compound objects that, directly or indirectly,
+    contain a reference to themselves) may cause a recursive loop
+
+ b) because deep copy copies *everything* it may copy too much, e.g.
+    administrative data structures that should be shared even between
+    copies
+
+Python's deep copy operation avoids these problems by:
+
+ a) keeping a table of objects already copied during the current
+    copying pass
+
+ b) letting user-defined classes override the copying operation or the
+    set of components copied
+
+This version does not copy types like module, class, function, method,
+nor stack trace, stack frame, nor file, socket, window, nor array, nor
+any similar types.
+
+Classes can use the same interfaces to control copying that they use
+to control pickling: they can define methods called __getinitargs__(),
+__getstate__() and __setstate__().  See the documentation for module
+"pickle" for information on these methods.

+#
+# Now some derived rules, where k is a duration (timedelta).
+#
+# 1. x.o = x.s + x.d
+#    This follows from the definition of x.s.
+#
+# 2. If x and y have the same tzinfo member, x.s = y.s.
+#    This is actually a requirement, an assumption we need to make about
+#    sane tzinfo classes.
+#
+# 3. The naive UTC time corresponding to x is x.n - x.o.
+#    This is again a requirement for a sane tzinfo class.
+#
+# 4. (x+k).s = x.s
+#    This follows from #2, and that datimetimetz+timedelta preserves tzinfo.
+#
+# 5. (x+k).n = x.n + k
+#    Again follows from how arithmetic is defined.
+#
+# Now we can explain tz.fromutc(x).  Let's assume it's an interesting case
+# (meaning that the various tzinfo methods exist, and don't blow up or return
+# None when called).
+#
+# The function wants to return a datetime y with timezone tz, equivalent to x.
+# x is already in UTC.
+#
+# By #3, we want
+#
+#     y.n - y.o = x.n                             [1]
+#
+# The algorithm starts by attaching tz to x.n, and calling that y.  So
+# x.n = y.n at the start.  Then it wants to add a duration k to y, so that [1]
+# becomes true; in effect, we want to solve [2] for k:
+#
+#    (y+k).n - (y+k).o = x.n                      [2]
+#
+# By #1, this is the same as
+#
+#    (y+k).n - ((y+k).s + (y+k).d) = x.n          [3]
+#
+# By #5, (y+k).n = y.n + k, which equals x.n + k because x.n=y.n at the start.
+# Substituting that into [3],
+#
+#    x.n + k - (y+k).s - (y+k).d = x.n; the x.n terms cancel, leaving
+#    k - (y+k).s - (y+k).d = 0; rearranging,
+#    k = (y+k).s - (y+k).d; by #4, (y+k).s == y.s, so
+#    k = y.s - (y+k).d
+#
+# On the RHS, (y+k).d can't be computed directly, but y.s can be, and we
+# approximate k by ignoring the (y+k).d term at first.  Note that k can't be
+# very large, since all offset-returning methods return a duration of magnitude
+# less than 24 hours.  For that reason, if y is firmly in std time, (y+k).d must
+# be 0, so ignoring it has no consequence then.
+#
+# In any case, the new value is
+#
+#     z = y + y.s                                 [4]
+#
+# It's helpful to step back at look at [4] from a higher level:  it's simply
+# mapping from UTC to tz's standard time.
+#
+# At this point, if
+#
+#     z.n - z.o = x.n                             [5]
+#
+# we have an equivalent time, and are almost done.  The insecurity here is
+# at the start of daylight time.  Picture US Eastern for concreteness.  The wall
+# time jumps from 1:59 to 3:00, and wall hours of the form 2:MM don't make good
+# sense then.  The docs ask that an Eastern tzinfo class consider such a time to
+# be EDT (because it's "after 2"), which is a redundant spelling of 1:MM EST
+# on the day DST starts.  We want to return the 1:MM EST spelling because that's
+# the only spelling that makes sense on the local wall clock.
+#
+# In fact, if [5] holds at this point, we do have the standard-time spelling,
+# but that takes a bit of proof.  We first prove a stronger result.  What's the
+# difference between the LHS and RHS of [5]?  Let
+#
+#     diff = x.n - (z.n - z.o)                    [6]
+#
+# Now
+#     z.n =                       by [4]
+#     (y + y.s).n =               by #5
+#     y.n + y.s =                 since y.n = x.n
+#     x.n + y.s =                 since z and y are have the same tzinfo member,
+#                                     y.s = z.s by #2
+#     x.n + z.s
+#
+# Plugging that back into [6] gives
+#
+#     diff =
+#     x.n - ((x.n + z.s) - z.o) =     expanding
+#     x.n - x.n - z.s + z.o =         cancelling
+#     - z.s + z.o =                   by #2
+#     z.d
+#
+# So diff = z.d.
+#
+# If [5] is true now, diff = 0, so z.d = 0 too, and we have the standard-time
+# spelling we wanted in the endcase described above.  We're done.  Contrarily,
+# if z.d = 0, then we have a UTC equivalent, and are also done.
+#
+# If [5] is not true now, diff = z.d != 0, and z.d is the offset we need to
+# add to z (in effect, z is in tz's standard time, and we need to shift the
+# local clock into tz's daylight time).
+#
+# Let
+#
+#     z' = z + z.d = z + diff                     [7]
+#
+# and we can again ask whether
+#
+#     z'.n - z'.o = x.n                           [8]
+#
+# If so, we're done.  If not, the tzinfo class is insane, according to the
+# assumptions we've made.  This also requires a bit of proof.  As before, let's
+# compute the difference between the LHS and RHS of [8] (and skipping some of
+# the justifications for the kinds of substitutions we've done several times
+# already):
+#
+#     diff' = x.n - (z'.n - z'.o) =           replacing z'.n via [7]
+#             x.n  - (z.n + diff - z'.o) =    replacing diff via [6]
+#             x.n - (z.n + x.n - (z.n - z.o) - z'.o) =
+#             x.n - z.n - x.n + z.n - z.o + z'.o =    cancel x.n
+#             - z.n + z.n - z.o + z'.o =              cancel z.n
+#             - z.o + z'.o =                      #1 twice
+#             -z.s - z.d + z'.s + z'.d =          z and z' have same tzinfo
+#             z'.d - z.d
+#
+# So z' is UTC-equivalent to x iff z'.d = z.d at this point.  If they are equal,
+# we've found the UTC-equivalent so are done.  In fact, we stop with [7] and
+# return z', not bothering to compute z'.d.
+#
+# How could z.d and z'd differ?  z' = z + z.d [7], so merely moving z' by
+# a dst() offset, and starting *from* a time already in DST (we know z.d != 0),
+# would have to change the result dst() returns:  we start in DST, and moving
+# a little further into it takes us out of DST.
+#
+# There isn't a sane case where this can happen.  The closest it gets is at
+# the end of DST, where there's an hour in UTC with no spelling in a hybrid
+# tzinfo class.  In US Eastern, that's 5:MM UTC = 0:MM EST = 1:MM EDT.  During
+# that hour, on an Eastern clock 1:MM is taken as being in standard time (6:MM
+# UTC) because the docs insist on that, but 0:MM is taken as being in daylight
+# time (4:MM UTC).  There is no local time mapping to 5:MM UTC.  The local
+# clock jumps from 1:59 back to 1:00 again, and repeats the 1:MM hour in
+# standard time.  Since that's what the local clock *does*, we want to map both
+# UTC hours 5:MM and 6:MM to 1:MM Eastern.  The result is ambiguous
+# in local time, but so it goes -- it's the way the local clock works.
+#
+# When x = 5:MM UTC is the input to this algorithm, x.o=0, y.o=-5 and y.d=0,
+# so z=0:MM.  z.d=60 (minutes) then, so [5] doesn't hold and we keep going.
+# z' = z + z.d = 1:MM then, and z'.d=0, and z'.d - z.d = -60 != 0 so [8]
+# (correctly) concludes that z' is not UTC-equivalent to x.
+#
+# Because we know z.d said z was in daylight time (else [5] would have held and
+# we would have stopped then), and we know z.d != z'.d (else [8] would have held
+# and we have stopped then), and there are only 2 possible values dst() can
+# return in Eastern, it follows that z'.d must be 0 (which it is in the example,
+# but the reasoning doesn't depend on the example -- it depends on there being
+# two possible dst() outcomes, one zero and the other non-zero).  Therefore
+# z' must be in standard time, and is the spelling we want in this case.
+#
+# Note again that z' is not UTC-equivalent as far as the hybrid tzinfo class is
+# concerned (because it takes z' as being in standard time rather than the
+# daylight time we intend here), but returning it gives the real-life "local
+# clock repeats an hour" behavior when mapping the "unspellable" UTC hour into
+# tz.
+#
+# When the input is 6:MM, z=1:MM and z.d=0, and we stop at once, again with
+# the 1:MM standard time spelling we want.
+#
+# So how can this break?  One of the assumptions must be violated.  Two
+# possibilities:
+#
+# 1) [2] effectively says that y.s is invariant across all y belong to a given
+#    time zone.  This isn't true if, for political reasons or continental drift,
+#    a region decides to change its base offset from UTC.
+#
+# 2) There may be versions of "double daylight" time where the tail end of
+#    the analysis gives up a step too early.  I haven't thought about that
+#    enough to say.
+#
+# In any case, it's clear that the default fromutc() is strong enough to handle
+# "almost all" time zones:  so long as the standard offset is invariant, it
+# doesn't matter if daylight time transition points change from year to year, or
+# if daylight time is skipped in some years; it doesn't matter how large or
+# small dst() may get within its bounds; and it doesn't even matter if some
+# perverse time zone returns a negative dst()).  So a breaking case must be
+# pretty bizarre, and a tzinfo subclass can override fromutc() if it is.

+- seems to contain a bug when updating...

+- reclaim free space (currently, space once occupied by deleted or expanded

+
+- support concurrent access (currently, if two processes take turns making
+updates, they can mess up the index)
+
+- support efficient access to large databases (currently, the whole index
+is read when the database is opened, and some updates rewrite the whole index)

+class Extension:
+    """Just a collection of attributes that describes an extension
+    module and everything needed to build it (hopefully in a portable
+    way, but there are hooks that let you be as unportable as you need).
+
+    Instance attributes:
+      name : string
+        the full name of the extension, including any packages -- ie.
+        *not* a filename or pathname, but Python dotted name
+      sources : [string]
+        list of source filenames, relative to the distribution root
+        (where the setup script lives), in Unix form (slash-separated)
+        for portability.  Source files may be C, C++, SWIG (.i),
+        platform-specific resource files, or whatever else is recognized
+        by the "build_ext" command as source for a Python extension.
+      include_dirs : [string]
+        list of directories to search for C/C++ header files (in Unix
+        form for portability)
+      define_macros : [(name : string, value : string|None)]
+        list of macros to define; each macro is defined using a 2-tuple,
+        where 'value' is either the string to define it to or None to
+        define it without a particular value (equivalent of "#define
+        FOO" in source or -DFOO on Unix C compiler command line)
+      undef_macros : [string]
+        list of macros to undefine explicitly
+      library_dirs : [string]
+        list of directories to search for C/C++ libraries at link time
+      libraries : [string]
+        list of library names (not filenames or paths) to link against
+      runtime_library_dirs : [string]
+        list of directories to search for C/C++ libraries at run time
+        (for shared extensions, this is when the extension is loaded)
+      extra_objects : [string]
+        list of extra files to link with (eg. object files not implied
+        by 'sources', static library that must be explicitly specified,
+        binary resource files, etc.)
+      extra_compile_args : [string]
+        any extra platform- and compiler-specific information to use
+        when compiling the source files in 'sources'.  For platforms and
+        compilers where "command line" makes sense, this is typically a
+        list of command-line arguments, but for other platforms it could
+        be anything.
+      extra_link_args : [string]
+        any extra platform- and compiler-specific information to use
+        when linking object files together to create the extension (or
+        to create a new static Python interpreter).  Similar
+        interpretation as for 'extra_compile_args'.
+      export_symbols : [string]
+        list of symbols to be exported from a shared extension.  Not
+        used on all platforms, and not generally necessary for Python
+        extensions, which typically export exactly one symbol: "init" +
+        extension_name.
+      swig_opts : [string]
+        any extra options to pass to SWIG if a source file has the .i
+        extension.
+      depends : [string]
+        list of files that the extension depends on
+      language : string
+        extension language (i.e. "c", "c++", "objc"). Will be detected
+        from the source extensions if not provided.
+      optional : boolean
+        specifies that a build failure in the extension should not abort the
+        build process, but simply not install the failing extension.

+
+# The rules according to Greg Stein:
+# 1) a version number has 1 or more numbers separated by a period or by
+#    sequences of letters. If only periods, then these are compared
+#    left-to-right to determine an ordering.
+# 2) sequences of letters are part of the tuple for comparison and are
+#    compared lexicographically
+# 3) recognize the numeric components may have leading zeroes
+#
+# The LooseVersion class below implements these rules: a version number
+# string is split up into a tuple of integer and string components, and
+# comparison is a simple tuple comparison.  This means that version
+# numbers behave in a predictable and obvious way, but a way that might
+# not necessarily be how people *want* version numbers to behave.  There
+# wouldn't be a problem if people could stick to purely numeric version
+# numbers: just split on period and compare the numbers as tuples.
+# However, people insist on putting letters into their version numbers;
+# the most common purpose seems to be:
+#   - indicating a "pre-release" version
+#     ('alpha', 'beta', 'a', 'b', 'pre', 'p')
+#   - indicating a post-release patch ('p', 'pl', 'patch')
+# but of course this can't cover all version number schemes, and there's
+# no way to know what a programmer means without asking him.
+#
+# The problem is what to do with letters (and other non-numeric
+# characters) in a version number.  The current implementation does the
+# obvious and predictable thing: keep them as strings and compare
+# lexically within a tuple comparison.  This has the desired effect if
+# an appended letter sequence implies something "post-release":
+# eg. "0.99" < "0.99pl14" < "1.0", and "5.001" < "5.001m" < "5.002".
+#
+# However, if letters in a version number imply a pre-release version,
+# the "obvious" thing isn't correct.  Eg. you would expect that
+# "1.5.1" < "1.5.2a2" < "1.5.2", but under the tuple/lexical comparison
+# implemented here, this just isn't so.
+#
+# Two possible solutions come to mind.  The first is to tie the
+# comparison algorithm to a particular set of semantic rules, as has
+# been done in the StrictVersion class above.  This works great as long
+# as everyone can go along with bondage and discipline.  Hopefully a
+# (large) subset of Python module programmers will agree that the
+# particular flavour of bondage and discipline provided by StrictVersion
+# provides enough benefit to be worth using, and will submit their
+# version numbering scheme to its domination.  The free-thinking
+# anarchists in the lot will never give in, though, and something needs
+# to be done to accommodate them.
+#
+# Perhaps a "moderately strict" version class could be implemented that
+# lets almost anything slide (syntactically), and makes some heuristic
+# assumptions about non-digits in version number strings.  This could
+# sink into special-case-hell, though; if I was as talented and
+# idiosyncratic as Larry Wall, I'd go ahead and implement a class that
+# somehow knows that "1.2.1" < "1.2.2a2" < "1.2.2" < "1.2.2pl3", and is
+# just as happy dealing with things like "2g6" and "1.13++".  I don't
+# think I'm smart enough to do it right though.
+#
+# In any case, I've coded the test suite for this module (see
+# ../test/test_version.py) specifically to fail on things like comparing
+# "1.2a2" and "1.2".  That's not because the *code* is doing anything
+# wrong, it's because the simple, obvious design doesn't match my
+# complicated, hairy expectations for real-world version numbers.  It
+# would be a snap to fix the test suite to say, "Yep, LooseVersion does
+# the Right Thing" (ie. the code matches the conception).  But I'd rather
+# have a conception that matches common notions about version numbers.

+######################################################################
+
+class DocTestRunner:
+    """
+    A class used to run DocTest test cases, and accumulate statistics.
+    The `run` method is used to process a single DocTest case.  It
+    returns a tuple `(f, t)`, where `t` is the number of test cases
+    tried, and `f` is the number of test cases that failed.
+
+        >>> tests = DocTestFinder().find(_TestClass)
+        >>> runner = DocTestRunner(verbose=False)
+        >>> tests.sort(key = lambda test: test.name)

+        _TestClass.get -> TestResults(failed=0, attempted=2)
+        _TestClass.square -> TestResults(failed=0, attempted=1)
+
+    The `summarize` method prints a summary of all the test cases that
+    have been run by the runner, and returns an aggregated `(f, t)`
+    tuple:
+
+        >>> runner.summarize(verbose=1)
+        4 items passed all tests:
+           2 tests in _TestClass
+           2 tests in _TestClass.__init__
+           2 tests in _TestClass.get
+           1 tests in _TestClass.square
+        7 tests in 4 items.
+        7 passed and 0 failed.
+        Test passed.
+        TestResults(failed=0, attempted=7)
+
+    The aggregated number of tried examples and failed examples is
+    also available via the `tries` and `failures` attributes:
+
+        >>> runner.tries
+        7
+        >>> runner.failures
+        0
+
+    The comparison between expected outputs and actual outputs is done
+    by an `OutputChecker`.  This comparison may be customized with a
+    number of option flags; see the documentation for `testmod` for
+    more information.  If the option flags are insufficient, then the
+    comparison may also be customized by passing a subclass of
+    `OutputChecker` to the constructor.
+
+    The test runner's display output can be controlled in two ways.
+    First, an output function (`out) can be passed to
+    `TestRunner.run`; this function will be called with strings that
+    should be displayed.  It defaults to `sys.stdout.write`.  If
+    capturing the output is not sufficient, then the display output
+    can be also customized by subclassing DocTestRunner, and
+    overriding the methods `report_start`, `report_success`,
+    `report_unexpected_exception`, and `report_failure`.

+#
+# for more information about charset see the charset module.  Here it is one
+# of the preferred MIME charset names (hopefully; you never know when parsing).
+# cte (Content Transfer Encoding) is either 'q' or 'b' (ignoring case).  In
+# theory other letters could be used for other encodings, but in practice this
+# (almost?) never happens.  There could be a public API for adding entries
+# to the CTE tables, but YAGNI for now.  'q' is Quoted Printable, 'b' is
+# Base64.  The meaning of encoded_string should be obvious.  'lang' is optional
+# as indicated by the brackets (they are not part of the syntax) but is almost
+# never encountered in practice.
+#
+# The general interface for a CTE decoder is that it takes the encoded_string
+# as its argument, and returns a tuple (cte_decoded_string, defects).  The
+# cte_decoded_string is the original binary that was encoded using the
+# specified cte.  'defects' is a list of MessageDefect instances indicating any
+# problems encountered during conversion.  'charset' and 'lang' are the
+# corresponding strings extracted from the EW, case preserved.
+#
+# The general interface for a CTE encoder is that it takes a binary sequence
+# as input and returns the cte_encoded_string, which is an ascii-only string.
+#
+# Each decoder must also supply a length function that takes the binary
+# sequence as its argument and returns the length of the resulting encoded
+# string.
+#
+# The main API functions for the module are decode, which calls the decoder
+# referenced by the cte specifier, and encode, which adds the appropriate

+"""Header value parser implementing various email-related RFC parsing rules.
+
+The parsing methods defined in this module implement various email related
+parsing rules.  Principal among them is RFC 5322, which is the followon
+to RFC 2822 and primarily a clarification of the former.  It also implements
+RFC 2047 encoded word decoding.
+
+RFC 5322 goes to considerable trouble to maintain backward compatibility with
+RFC 822 in the parse phase, while cleaning up the structure on the generation
+phase.  This parser supports correct RFC 5322 generation by tagging white space
+as folding white space only when folding is allowed in the non-obsolete rule
+sets.  Actually, the parser is even more generous when accepting input than RFC
+5322 mandates, following the spirit of Postel's Law, which RFC 5322 encourages.
+Where possible deviations from the standard are annotated on the 'defects'
+attribute of tokens that deviate.
+
+The general structure of the parser follows RFC 5322, and uses its terminology
+where there is a direct correspondence.  Where the implementation requires a
+somewhat different structure than that used by the formal grammar, new terms
+that mimic the closest existing terms are used.  Thus, it really helps to have
+a copy of RFC 5322 handy when studying this code.
+
+Input to the parser is a string that has already been unfolded according to
+RFC 5322 rules.  According to the RFC this unfolding is the very first step, and
+this parser leaves the unfolding step to a higher level message parser, which
+will have already detected the line breaks that need unfolding while
+determining the beginning and end of each header.
+
+The output of the parser is a TokenList object, which is a list subclass.  A
+TokenList is a recursive data structure.  The terminal nodes of the structure
+are Terminal objects, which are subclasses of str.  These do not correspond
+directly to terminal objects in the formal grammar, but are instead more
+practical higher level combinations of true terminals.
+
+All TokenList and Terminal objects have a 'value' attribute, which produces the
+semantically meaningful value of that part of the parse subtree.  The value of
+all whitespace tokens (no matter how many sub-tokens they may contain) is a
+single space, as per the RFC rules.  This includes 'CFWS', which is herein
+included in the general class of whitespace tokens.  There is one exception to
+the rule that whitespace tokens are collapsed into single spaces in values: in
+the value of a 'bare-quoted-string' (a quoted-string with no leading or
+trailing whitespace), any whitespace that appeared between the quotation marks
+is preserved in the returned value.  Note that in all Terminal strings quoted
+pairs are turned into their unquoted values.
+
+All TokenList and Terminal objects also have a string value, which attempts to
+be a "canonical" representation of the RFC-compliant form of the substring that
+produced the parsed subtree, including minimal use of quoted pair quoting.
+Whitespace runs are not collapsed.
+
+Comment tokens also have a 'content' attribute providing the string found
+between the parens (including any nested comments) with whitespace preserved.
+
+All TokenList and Terminal objects have a 'defects' attribute which is a
+possibly empty list all of the defects found while creating the token.  Defects
+may appear on any token in the tree, and a composite list of all defects in the
+subtree is available through the 'all_defects' attribute of any node.  (For
+Terminal notes x.defects == x.all_defects.)
+
+Each object in a parse tree is called a 'token', and each has a 'token_type'
+attribute that gives the name from the RFC 5322 grammar that it represents.
+Not all RFC 5322 nodes are produced, and there is one non-RFC 5322 node that
+may be produced: 'ptext'.  A 'ptext' is a string of printable ascii characters.
+It is returned in place of lists of (ctext/quoted-pair) and
+(qtext/quoted-pair).
+
+XXX: provide complete list of token types.

+    #   folded: the result accumulator.  This is an instance of _Folded.
+    #       (XXX: I haven't finished factoring this out yet, the folding code
+    #       pretty much uses this as a state object.) When the folded.current
+    #       contains as much text as will fit, the _fold method should call
+    #       folded.newline.
+    #  folded.lastlen: the current length of the test stored in folded.current.
+    #  folded.maxlen: The maximum number of characters that may appear on a
+    #       folded line.  Differs from the policy setting in that "no limit" is
+    #       represented by +inf, which means it can be used in the trivially
+    #       logical fashion in comparisons.
+    #
+    # Currently no subclasses implement parts, and I think this will remain
+    # true.  A subclass only needs to implement _fold when the generic version
+    # isn't sufficient.  _fold will need to be implemented primarily when it is
+    # possible for encoded words to appear in the specialized token-list, since
+    # there is no generic algorithm that can know where exactly the encoded
+    # words are allowed.  A _fold implementation is responsible for filling
+    # lines in the same general way that the top level _fold does. It may, and
+    # should, call the _fold method of sub-objects in a similar fashion to that
+    # of the top level _fold.
+    #
+    # XXX: I'm hoping it will be possible to factor the existing code further
+    # to reduce redundancy and make the logic clearer.

+:mod:`email` Package Architecture
+=================================
+
+Overview
+--------
+
+The email package consists of three major components:
+
+    Model
+        An object structure that represents an email message, and provides an
+        API for creating, querying, and modifying a message.
+
+    Parser
+        Takes a sequence of characters or bytes and produces a model of the
+        email message represented by those characters or bytes.
+
+    Generator
+        Takes a model and turns it into a sequence of characters or bytes.  The
+        sequence can either be intended for human consumption (a printable
+        unicode string) or bytes suitable for transmission over the wire.  In
+        the latter case all data is properly encoded using the content transfer
+        encodings specified by the relevant RFCs.
+
+Conceptually the package is organized around the model.  The model provides both
+"external" APIs intended for use by application programs using the library,
+and "internal" APIs intended for use by the Parser and Generator components.
+This division is intentionally a bit fuzzy; the API described by this
+documentation is all a public, stable API.  This allows for an application
+with special needs to implement its own parser and/or generator.
+
+In addition to the three major functional components, there is a third key
+component to the architecture:
+
+    Policy
+        An object that specifies various behavioral settings and carries
+        implementations of various behavior-controlling methods.
+
+The Policy framework provides a simple and convenient way to control the
+behavior of the library, making it possible for the library to be used in a
+very flexible fashion while leveraging the common code required to parse,
+represent, and generate message-like objects.  For example, in addition to the
+default :rfc:`5322` email message policy, we also have a policy that manages
+HTTP headers in a fashion compliant with :rfc:`2616`.  Individual policy
+controls, such as the maximum line length produced by the generator, can also
+be controlled individually to meet specialized application requirements.
+
+
+The Model
+---------
+
+The message model is implemented by the :class:`~email.message.Message` class.
+The model divides a message into the two fundamental parts discussed by the
+RFC: the header section and the body.  The `Message` object acts as a
+pseudo-dictionary of named headers.  Its dictionary interface provides
+convenient access to individual headers by name.  However, all headers are kept
+internally in an ordered list, so that the information about the order of the
+headers in the original message is preserved.
+
+The `Message` object also has a `payload` that holds the body.  A `payload` can
+be one of two things: data, or a list of `Message` objects.  The latter is used
+to represent a multipart MIME message.  Lists can be nested arbitrarily deeply
+in order to represent the message, with all terminal leaves having non-list
+data payloads.
+
+
+Message Lifecycle
+-----------------
+
+The general lifecyle of a message is:
+
+    Creation
+        A `Message` object can be created by a Parser, or it can be
+        instantiated as an empty message by an application.
+
+    Manipulation
+        The application may examine one or more headers, and/or the
+        payload, and it may modify one or more headers and/or
+        the payload.  This may be done on the top level `Message`
+        object, or on any sub-object.
+
+    Finalization
+        The Model is converted into a unicode or binary stream,
+        or the model is discarded.
+
+
+
+Header Policy Control During Lifecycle
+--------------------------------------
+
+One of the major controls exerted by the Policy is the management of headers
+during the `Message` lifecycle.  Most applications don't need to be aware of
+this.
+
+A header enters the model in one of two ways: via a Parser, or by being set to
+a specific value by an application program after the Model already exists.
+Similarly, a header exits the model in one of two ways: by being serialized by
+a Generator, or by being retrieved from a Model by an application program.  The
+Policy object provides hooks for all four of these pathways.
+
+The model storage for headers is a list of (name, value) tuples.
+
+The Parser identifies headers during parsing, and passes them to the
+:meth:`~email.policy.Policy.header_source_parse` method of the Policy.  The
+result of that method is the (name, value) tuple to be stored in the model.
+
+When an application program supplies a header value (for example, through the
+`Message` object `__setitem__` interface), the name and the value are passed to
+the :meth:`~email.policy.Policy.header_store_parse` method of the Policy, which
+returns the (name, value) tuple to be stored in the model.
+
+When an application program retrieves a header (through any of the dict or list
+interfaces of `Message`), the name and value are passed to the
+:meth:`~email.policy.Policy.header_fetch_parse` method of the Policy to
+obtain the value returned to the application.
+
+When a Generator requests a header during serialization, the name and value are
+passed to the :meth:`~email.policy.Policy.fold` method of the Policy, which
+returns a string containing line breaks in the appropriate places.  The
+:meth:`~email.policy.Policy.cte_type` Policy control determines whether or
+not Content Transfer Encoding is performed on the data in the header.  There is
+also a :meth:`~email.policy.Policy.binary_fold` method for use by generators
+that produce binary output, which returns the folded header as binary data,
+possibly folded at different places than the corresponding string would be.
+
+
+Handling Binary Data
+--------------------
+
+In an ideal world all message data would conform to the RFCs, meaning that the
+parser could decode the message into the idealized unicode message that the
+sender originally wrote.  In the real world, the email package must also be
+able to deal with badly formatted messages, including messages containing
+non-ASCII characters that either have no indicated character set or are not
+valid characters in the indicated character set.
+
+Since email messages are *primarily* text data, and operations on message data
+are primarily text operations (except for binary payloads of course), the model
+stores all text data as unicode strings.  Un-decodable binary inside text
+data is handled by using the `surrogateescape` error handler of the ASCII
+codec.  As with the binary filenames the error handler was introduced to
+handle, this allows the email package to "carry" the binary data received
+during parsing along until the output stage, at which time it is regenerated
+in its original form.
+
+This carried binary data is almost entirely an implementation detail.  The one
+place where it is visible in the API is in the "internal" API.  A Parser must
+do the `surrogateescape` encoding of binary input data, and pass that data to
+the appropriate Policy method.  The "internal" interface used by the Generator
+to access header values preserves the `surrogateescaped` bytes.  All other
+interfaces convert the binary data either back into bytes or into a safe form
+(losing information in some cases).
+
+
+Backward Compatibility
+----------------------
+
+The :class:`~email.policy.Policy.Compat32` Policy provides backward
+compatibility with version 5.1 of the email package.  It does this via the
+following implementation of the four+1 Policy methods described above:
+
+header_source_parse
+    Splits the first line on the colon to obtain the name, discards any spaces
+    after the colon, and joins the remainder of the line with all of the
+    remaining lines, preserving the linesep characters to obtain the value.
+    Trailing carriage return and/or linefeed characters are stripped from the
+    resulting value string.
+
+header_store_parse
+    Returns the name and value exactly as received from the application.
+
+header_fetch_parse
+    If the value contains any `surrogateescaped` binary data, return the value
+    as a :class:`~email.header.Header` object, using the character set
+    `unknown-8bit`.  Otherwise just returns the value.
+
+fold
+    Uses :class:`~email.header.Header`'s folding to fold headers in the
+    same way the email5.1 generator did.
+
+binary_fold
+    Same as fold, but encodes to 'ascii'.
+
+
+New Algorithm
+-------------
+
+header_source_parse
+    Same as legacy behavior.
+
+header_store_parse
+    Same as legacy behavior.
+
+header_fetch_parse
+    If the value is already a header object, returns it.  Otherwise, parses the
+    value using the new parser, and returns the resulting object as the value.
+    `surrogateescaped` bytes get turned into unicode unknown character code
+    points.
+
+fold
+    Uses the new header folding algorithm, respecting the policy settings.
+    surrogateescaped bytes are encoded using the ``unknown-8bit`` charset for
+    ``cte_type=7bit`` or ``8bit``.  Returns a string.
+
+    At some point there will also be a ``cte_type=unicode``, and for that
+    policy fold will serialize the idealized unicode message with RFC-like
+    folding, converting any surrogateescaped bytes into the unicode
+    unknown character glyph.
+
+binary_fold
+    Uses the new header folding algorithm, respecting the policy settings.
+    surrogateescaped bytes are encoded using the `unknown-8bit` charset for
+    ``cte_type=7bit``, and get turned back into bytes for ``cte_type=8bit``.
+    Returns bytes.
+
+    At some point there will also be a ``cte_type=unicode``, and for that
+    policy binary_fold will serialize the message according to :rfc:``5335``.

+"""FeedParser - An email feed parser.
+
+The feed parser implements an interface for incrementally parsing an email
+message, line by line.  This has advantages for certain applications, such as
+those reading email messages off a socket.
+
+FeedParser.feed() is the primary interface for pushing new data into the
+parser.  It returns when there's nothing more it can do with the available
+data.  When you have no more data to push into the parser, call .close().
+This completes the parsing and returns the root message object.
+
+The other advantage of this parser is that it will never raise a parsing
+exception.  Instead, when it finds something unexpected, it adds a 'defect' to
+the current message.  Defects are just instances that live on the message
+object's .defects attribute.

+    contain one key, 'defects', initialized to an empty list.  After the call

+    insofar as practical, raise any errors.  Defects should be added to the
+    list instead.  The standard header parsers register defects for RFC
+    compliance issues, for obsolete RFC syntax, and for unrecoverable parsing
+    errors.
+
+    The parse method may add additional keys to the dictionary.  In this case
+    the subclass must define an 'init' method, which will be passed the
+    dictionary as its keyword arguments.  The method should use (usually by
+    setting them as the value of similarly named attributes) and remove all the
+    extra keys added by its parse method, and then use super to call its parent
+    class with the remaining arguments and keywords.

+
+    The API extensions enabled by this policy are currently provisional.

+
+    This policy adds new header parsing and folding algorithms.  Instead of
+    simple strings, headers are custom objects with custom attributes
+    depending on the type of the field.  The folding algorithm fully
+    implements RFCs 2047 and 5322.

+    all Policies, this policy adds the following additional attributes:
+
+    refold_source       -- if the value for a header in the Message object

+                           stream form.  The possible values are:

+                           header.  A default header_factory is provided that
+                           understands some of the RFC5322 header field types.

+"""Quoted-printable content transfer encoding per RFCs 2045-2047.
+
+This module handles the content transfer encoding method defined in RFC 2045
+to encode US ASCII-like 8-bit data called `quoted-printable'.  It is used to
+safely encode text that is in a character set similar to the 7-bit US ASCII
+character set, but that includes some 8-bit characters that are normally not
+allowed in email bodies or headers.
+
+Quoted-printable is very space-inefficient for encoding binary files; use the
+email.base64mime module for that instead.
+
+This module provides an interface to encode and decode both headers and bodies
+with quoted-printable encoding.
+
+RFC 2045 defines a method for including character set information in an
+`encoded-word' in a header.  This method is commonly used for 8-bit real names
+in To:/From:/Cc: etc. fields, as well as Subject: lines.
+
+This module does not do the line wrapping or end-of-line character
+conversion necessary for proper internationalized headers; it only
+does dumb encoding and decoding.  To deal with the various line
+wrapping issues, use the email.header module.

+
+    To create a connection, call the class using these arguments:
+            host, user, passwd, acct, timeout
+
+    The first four arguments are all strings, and have default value ''.
+    timeout must be numeric and defaults to None if not passed,
+    meaning that no timeout will be set on any ftp socket(s)
+    If a timeout is passed, then this is now the default timeout for all ftp
+    socket operations for this instance.
+
+    Then use self.connect() with optional host and port argument.
+
+    To download a file, use ftp.retrlines('RETR ' + filename),
+    or ftp.retrbinary() with slightly different arguments.
+    To upload a file, use ftp.storlines() or ftp.storbinary(),
+    which have an open file as argument (see their definitions
+    below for details).
+    The download/upload functions first issue appropriate TYPE
+    and PORT or PASV commands.

+################################################################################
+
+# The correct way to indicate that a comparison operation doesn't
+# recognise the other type is to return NotImplemented and let the
+# interpreter handle raising TypeError if both operands return
+# NotImplemented from their respective comparison methods
+#
+# This makes the implementation of total_ordering more complicated, since
+# we need to be careful not to trigger infinite recursion when two
+# different types that both use this decorator encounter each other.
+#
+# For example, if a type implements __lt__, it's natural to define
+# __gt__ as something like:
+#
+#    lambda self, other: not self < other and not self == other
+#
+# However, using the operator syntax like that ends up invoking the full
+# type checking machinery again and means we can end up bouncing back and
+# forth between the two operands until we run out of stack space.
+#
+# The solution is to define helper functions that invoke the appropriate
+# magic methods directly, ensuring we only try each operand once, and
+# return NotImplemented immediately if it is returned from the
+# underlying user provided method. Using this scheme, the __gt__ derived
+# from a user provided __lt__ becomes:

+
+        At least one of fileobj and filename must be given a
+        non-trivial value.
+
+        The new class instance is based on fileobj, which can be a regular
+        file, an io.BytesIO object, or any other object which simulates a file.
+        It defaults to None, in which case filename is opened to provide
+        a file object.
+
+        When fileobj is not None, the filename argument is only used to be
+        included in the gzip file header, which may includes the original
+        filename of the uncompressed file.  It defaults to the filename of
+        fileobj, if discernible; otherwise, it defaults to the empty string,
+        and in this case the original filename is not included in the header.
+
+        The mode argument can be any of 'r', 'rb', 'a', 'ab', 'w', 'wb', 'x', or
+        'xb' depending on whether the file will be read or written.  The default
+        is the mode of fileobj if discernible; otherwise, the default is 'rb'.
+        A mode of 'r' is equivalent to one of 'rb', and similarly for 'w' and
+        'wb', 'a' and 'ab', and 'x' and 'xb'.
+
+        The compresslevel argument is an integer from 0 to 9 controlling the
+        level of compression; 1 is fastest and produces the least compression,
+        and 9 is slowest and produces the most compression. 0 is no compression
+        at all. The default is 9.
+
+        The mtime argument is an optional numeric timestamp to be written
+        to the stream when compressing.  All gzip compressed streams
+        are required to contain a timestamp.  If omitted or None, the
+        current time is used.  This module ignores the timestamp when
+        decompressing; however, some programs, such as gunzip, make use
+        of it.  The format of the timestamp is the same as that of the
+        return value of time.time() and of the st_mtime member of the

+__doc__ = """hashlib module - A common interface to many hash functions.
+
+new(name, data=b'') - returns a new hash object implementing the
+                      given hash function; initializing the hash
+                      using the given binary data.
+
+Named constructor functions are also available, these are faster
+than using new(name):
+
+md5(), sha1(), sha224(), sha256(), sha384(), and sha512()
+
+More algorithms may be available on your platform but the above are guaranteed
+to exist.  See the algorithms_guaranteed and algorithms_available attributes
+to find out what algorithm names can be passed to new().
+
+NOTE: If you want the adler32 or crc32 hash functions they are available in
+the zlib module.
+
+Choose your hash function wisely.  Some have known collision weaknesses.
+sha384 and sha512 will be slow on 32 bit platforms.
+
+Hash objects have these methods:
+ - update(arg): Update the hash object with the bytes in arg. Repeated calls
+                are equivalent to a single call with the concatenation of all
+                the arguments.
+ - digest():    Return the digest of the bytes passed to the update() method
+                so far.
+ - hexdigest(): Like digest() except the digest is returned as a unicode
+                object of double length, containing only hexadecimal digits.
+ - copy():      Return a copy (clone) of the hash object. This can be used to
+                efficiently compute the digests of strings that share a common
+                initial substring.
+
+For example, to obtain the digest of the string 'Nobody inspects the
+spammish repetition':
+
+    >>> import hashlib
+    >>> m = hashlib.md5()
+    >>> m.update(b"Nobody inspects")
+    >>> m.update(b" the spammish repetition")
+    >>> m.digest()
+    b'\\xbbd\\x9c\\x83\\xdd\\x1e\\xa5\\xc9\\xd9\\xde\\xc9\\xa1\\x8d\\xf0\\xff\\xe9'
+
+More condensed:
+
+    >>> hashlib.sha224(b"Nobody inspects the spammish repetition").hexdigest()
+    'a4337bc45a8fc544c03f52dc550cd6e1e87021bc896588bd79e901e2'

+"""HTTP/1.1 client library
+
+<intro stuff goes here>
+<other stuff, too>
+
+HTTPConnection goes through a number of "states", which define when a client
+may legally make another request or fetch the response for a particular
+request. This diagram details these state transitions:
+
+    (null)
+      |
+      | HTTPConnection()
+      v
+    Idle
+      |
+      | putrequest()
+      v
+    Request-started
+      |
+      | ( putheader() )*  endheaders()
+      v
+    Request-sent
+      |
+      | response = getresponse()
+      v
+    Unread-response   [Response-headers-read]
+      |\____________________
+      |                     |
+      | response.read()     | putrequest()
+      v                     v
+    Idle                  Req-started-unread-response
+                     ______/|
+                   /        |
+   response.read() |        | ( putheader() )*  endheaders()
+                   v        v
+       Request-started    Req-sent-unread-response
+                            |
+                            | response.read()
+                            v
+                          Request-sent
+
+This diagram presents the following rules:
+  -- a second request may not be started until {response-headers-read}
+  -- a response [object] cannot be retrieved until {request-sent}
+  -- there is no differentiation between an unread response body and a
+     partially read response body
+
+Note: this enforcement is applied by the HTTPConnection class. The
+      HTTPResponse class does not enforce this state machine, which
+      implies sophisticated clients may accelerate the request/response
+      pipeline. Caution should be taken, though: accelerating the states
+      beyond the above pattern may imply knowledge of the server's
+      connection-close behavior for certain requests. For example, it
+      is impossible to tell whether the server will close the connection
+      UNTIL the response headers have been read; this means that further
+      requests cannot be placed into the pipeline until it is known that
+      the server will NOT be closing the connection.
+
+Logical State                  __state            __response

+
+    This class differs from CookieJar only in the format it uses to save and
+    load cookies to and from a file.  This class uses the Mozilla/Netscape
+    `cookies.txt' format.  lynx uses this file format, too.
+
+    Don't expect cookies saved while the browser is running to be noticed by
+    the browser (in fact, Mozilla on unix will overwrite your saved cookies if
+    you change them on disk while it's running; on Windows, you probably can't
+    save at all while the browser is running).
+
+    Note that the Mozilla/Netscape format will downgrade RFC2965 cookies to
+    Netscape cookies on saving.
+
+    In particular, the cookie version and port number information is lost,
+    together with information about whether or not Path, Port and Discard were
+    specified by the Set-Cookie2 (or Set-Cookie) header, and whether or not the

+#
+#  Cookie.py is a Python module for the handling of HTTP
+#  cookies as a Python dictionary.  See RFC 2109 for more
+#  information on cookies.
+#
+#  The original idea to treat Cookies as a dictionary came from
+#  Dave Mitchell (davem@magnet.com) in 1995, when he released the
+#  first version of nscookie.py.
+#
+####
+
+r"""
+Here's a sample session to show how to use this module.
+At the moment, this is the only documentation.
+
+The Basics
+----------
+
+Importing is easy...
+
+   >>> from http import cookies
+
+Most of the time you start by creating a cookie.
+
+   >>> C = cookies.SimpleCookie()
+
+Once you've created your Cookie, you can add values just as if it were
+a dictionary.
+
+   >>> C = cookies.SimpleCookie()
+   >>> C["fig"] = "newton"
+   >>> C["sugar"] = "wafer"
+   >>> C.output()
+   'Set-Cookie: fig=newton\r\nSet-Cookie: sugar=wafer'
+
+Notice that the printable representation of a Cookie is the
+appropriate format for a Set-Cookie: header.  This is the
+default behavior.  You can change the header and printed
+attributes by using the .output() function
+
+   >>> C = cookies.SimpleCookie()
+   >>> C["rocky"] = "road"
+   >>> C["rocky"]["path"] = "/cookie"
+   >>> print(C.output(header="Cookie:"))
+   Cookie: rocky=road; Path=/cookie
+   >>> print(C.output(attrs=[], header="Cookie:"))
+   Cookie: rocky=road
+
+The load() method of a Cookie extracts cookies from a string.  In a
+CGI script, you would use this method to extract the cookies from the
+HTTP_COOKIE environment variable.
+
+   >>> C = cookies.SimpleCookie()
+   >>> C.load("chips=ahoy; vienna=finger")
+   >>> C.output()
+   'Set-Cookie: chips=ahoy\r\nSet-Cookie: vienna=finger'
+
+The load() method is darn-tootin smart about identifying cookies
+within a string.  Escaped quotation marks, nested semicolons, and other
+such trickeries do not confuse it.
+
+   >>> C = cookies.SimpleCookie()
+   >>> C.load('keebler="E=everybody; L=\\"Loves\\"; fudge=\\012;";')
+   >>> print(C)
+   Set-Cookie: keebler="E=everybody; L=\"Loves\"; fudge=\012;"
+
+Each element of the Cookie also supports all of the RFC 2109
+Cookie attributes.  Here's an example which sets the Path
+attribute.
+
+   >>> C = cookies.SimpleCookie()
+   >>> C["oreo"] = "doublestuff"
+   >>> C["oreo"]["path"] = "/"
+   >>> print(C)
+   Set-Cookie: oreo=doublestuff; Path=/
+
+Each dictionary element has a 'value' attribute, which gives you
+back the value associated with the key.
+
+   >>> C = cookies.SimpleCookie()
+   >>> C["twix"] = "none for you"
+   >>> C["twix"].value
+   'none for you'
+
+The SimpleCookie expects that all values should be standard strings.
+Just to be sure, SimpleCookie invokes the str() builtin to convert
+the value to a string, when the values are set dictionary-style.
+
+   >>> C = cookies.SimpleCookie()
+   >>> C["number"] = 7
+   >>> C["string"] = "seven"
+   >>> C["number"].value
+   '7'
+   >>> C["string"].value
+   'seven'
+   >>> C.output()
+   'Set-Cookie: number=7\r\nSet-Cookie: string=seven'
+
+Finis.

+# a two-way quoting algorithm.  Any non-text character is translated

+

+
+    The following explanation of HTTP serves to guide you through the
+    code as well as to expose any misunderstandings I may have about
+    HTTP (so you don't need to read the code to figure out I'm wrong
+    :-).
+
+    HTTP (HyperText Transfer Protocol) is an extensible protocol on
+    top of a reliable stream transport (e.g. TCP/IP).  The protocol
+    recognizes three parts to a request:
+
+    1. One line identifying the request type and path
+    2. An optional set of RFC-822-style headers
+    3. An optional data part
+
+    The headers and data are separated by a blank line.
+
+    The first line of the request has the form
+
+    <command> <path> <version>
+
+    where <command> is a (case-sensitive) keyword such as GET or POST,
+    <path> is a string containing path information for the request,
+    and <version> should be the string "HTTP/1.0" or "HTTP/1.1".
+    <path> is encoded using the URL encoding scheme (using %xx to signify
+    the ASCII character with hex code xx).
+
+    The specification specifies that lines are separated by CRLF but
+    for compatibility with the widest range of clients recommends
+    servers also handle LF.  Similarly, whitespace in the request line
+    is treated sensibly (allowing multiple spaces between components
+    and allowing trailing whitespace).
+
+    Similarly, for output, lines ought to be separated by CRLF pairs
+    but most clients grok LF characters just fine.
+
+    If the first line of the request has the form
+
+    <command> <path>
+
+    (i.e. <version> is left out) then this is assumed to be an HTTP
+    0.9 request; this form has no optional headers and data part and
+    the reply consists of just the data.
+
+    The reply form of the HTTP 1.x protocol again has three parts:
+
+    1. One line giving the response code
+    2. An optional set of RFC-822-style headers
+    3. The data
+
+    Again, the headers and data are separated by a blank line.
+
+    The response code line has the form
+
+    <version> <responsecode> <responsestring>
+
+    where <version> is the protocol version ("HTTP/1.0" or "HTTP/1.1"),
+    <responsecode> is a 3-digit response code indicating success or
+    failure of the request, and <responsestring> is an optional
+    human-readable string explaining what the response code means.
+
+    This server parses the request and the headers, and then calls a
+    function specific to the request type (<command>).  Specifically,
+    a request SPAM will be handled by a method do_SPAM().  If no
+    such method exists the server sends an error response to the
+    client.  If it exists, it is called with no arguments:
+
+    do_SPAM()
+
+    Note that the request name is case sensitive (i.e. SPAM and spam
+    are different requests).
+
+    The various request details are stored in instance variables:
+
+    - client_address is the client IP address in the form (host,
+    port);
+
+    - command, path and version are the broken-down request line;
+
+    - headers is an instance of email.message.Message (or a derived
+    class) containing the header information;
+
+    - rfile is a file object open for reading positioned at the
+    start of the optional input data part;
+
+    - wfile is a file object open for writing.
+
+    IT IS IMPORTANT TO ADHERE TO THE PROTOCOL FOR WRITING!
+
+    The first thing to be written must be the response line.  Then
+    follow 0 or more header lines, then a blank line, and then the
+    actual data (if any).  The meaning of the header lines depends on
+    the command executed by the server; in most cases, when data is
+    returned, there should be at least one header line of the form
+
+    Content-type: <type>/<subtype>
+
+    where <type> and <subtype> should be registered MIME types,
+    e.g. "text/html" or "text/plain".

+IDLE is Python's Tkinter-based Integrated DeveLopment Environment.
+
+IDLE emphasizes a lightweight, clean design with a simple user interface.
+Although it is suitable for beginners, even advanced users will find that
+IDLE has everything they really need to develop pure Python code.
+
+IDLE features a multi-window text editor with multiple undo, Python colorizing,
+and many other capabilities, e.g. smart indent, call tips, and autocompletion.
+
+The editor has comprehensive search functions, including searching through
+multiple files.  Class browsers and path browsers provide fast access to
+code objects from a top level viewpoint without dealing with code folding.
+
+There is a Python Shell window which features colorizing and command recall.
+
+IDLE executes Python code in a separate process, which is restarted for each
+Run (F5) initiated from an editor window.  The environment can also be 
+restarted from the Shell window without restarting IDLE.
+
+This enhancement has often been requested, and is now finally available.  The
+magic "reload/import *" incantations are no longer required when editing and
+testing a module two or three steps down the import chain.
+
+(Personal firewall software may warn about the connection IDLE makes to its
+subprocess using this computer's internal loopback interface.  This connection
+is not visible on any external interface and no data is sent to or received
+from the Internet.)
+
+It is possible to interrupt tightly looping user code, even on Windows.
+
+Applications which cannot support subprocesses and/or sockets can still run
+IDLE in a single process.
+
+IDLE has an integrated debugger with stepping, persistent breakpoints, and call
+stack visibility.
+
+There is a GUI configuration manager which makes it easy to select fonts,
+colors, keybindings, and startup options.  This facility includes a feature
+which allows the user to specify additional help sources, either locally or on
+the web.
+
+IDLE is coded in 100% pure Python, using the Tkinter GUI toolkit (Tk/Tcl)
+and is cross-platform, working on Unix, Mac, and Windows.
+
+IDLE accepts command line arguments.  Try idle -h to see the options.
+
+
+If you find bugs or have suggestions or patches, let us know about
+them by using the Python issue tracker:
+
+http://bugs.python.org
+
+For further details and links, read the Help files and check the IDLE home
+page at
+
+http://www.python.org/idle/
+
+There is a mail list for IDLE: idle-dev@python.org.  You can join at

+[See the end of this file for ** TIPS ** on using IDLE !!]
+
+IDLE is the Python IDE built with the tkinter GUI toolkit.
+
+IDLE has the following features:
+-coded in 100% pure Python, using the tkinter GUI toolkit
+-cross-platform: works on Windows, Unix, and OS X
+-multi-window text editor with multiple undo, Python colorizing, smart indent,
+call tips, and many other features
+-Python shell window (a.k.a interactive interpreter)
+-debugger (not complete, but you can set breakpoints, view and step)
+
+Menus:
+
+IDLE has two window types the Shell window and the Editor window. It is
+possible to have multiple editor windows simultaneously. IDLE's
+menus dynamically change based on which window is currently selected. Each menu
+documented below indicates which window type it is associated with. Click on
+the dotted line at the top of a menu to "tear it off": a separate window
+containing the menu is created (for Unix and Windows only).
+
+File Menu (Shell and Editor):
+
+        New File         -- Create a new file editing window
+        Open...          -- Open an existing file
+        Open Module...   -- Open an existing module (searches sys.path)

+        Save             -- Save current window to the associated file (unsaved
+                            windows have a * before and after the window title)
+
+        Save As...       -- Save current window to new file, which becomes
+                            the associated file
+        Save Copy As...  -- Save current window to different file
+                            without changing the associated file
+        ---
+        Print Window     -- Print the current window

+        Exit             -- Close all windows, quit (asks to save if unsaved)
+
+Edit Menu (Shell and Editor):
+

+** TIPS **
+==========
+
+Additional Help Sources:
+
+        Windows users can Google on zopeshelf.chm to access Zope help files in
+        the Windows help format.  The Additional Help Sources feature of the
+        configuration GUI supports .chm, along with any other filetypes
+        supported by your browser.  Supply a Menu Item title, and enter the
+        location in the Help File Path slot of the New Help Source dialog.  Use
+        http:// and/or www. to identify external URLs, or download the file and
+        browse for its path on your machine using the Browse button.
+
+        All users can access the extensive sources of help, including
+        tutorials, available at docs.python.org.  Selected URLs can be added
+        or removed from the Help menu at any time using Configure IDLE.
+
+Basic editing and navigation:
+
+        Backspace deletes char to the left; DEL deletes char to the right.
+        Control-backspace deletes word left, Control-DEL deletes word right.
+        Arrow keys and Page Up/Down move around.
+        Control-left/right Arrow moves by words in a strange but useful way.
+        Home/End go to begin/end of line.
+        Control-Home/End go to begin/end of file.
+        Some useful Emacs bindings are inherited from Tcl/Tk:
+                Control-a     beginning of line
+                Control-e     end of line
+                Control-k     kill line (but doesn't put it in clipboard)
+                Control-l     center window around the insertion point
+        Standard keybindings (like Control-c to copy and Control-v to
+        paste) may work.  Keybindings are selected in the Configure IDLE
+        dialog.
+
+Automatic indentation:
+
+        After a block-opening statement, the next line is indented by 4 spaces
+        (in the Python Shell window by one tab).  After certain keywords
+        (break, return etc.) the next line is dedented.  In leading
+        indentation, Backspace deletes up to 4 spaces if they are there.  Tab
+        inserts spaces (in the Python Shell window one tab), number depends on
+        Indent Width. Currently tabs are restricted to four spaces due
+        to Tcl/Tk limitations.
+
+        See also the indent/dedent region commands in the edit menu.
+
+Completions:
+
+        Completions are supplied for functions, classes, and attributes of
+        classes, both built-in and user-defined.  Completions are also provided
+        for filenames.
+
+        The AutoCompleteWindow (ACW) will open after a predefined delay
+        (default is two seconds) after a '.' or (in a string) an os.sep is
+        typed.  If after one of those characters (plus zero or more other
+        characters) a tab is typed the ACW will open immediately if a possible
+        continuation is found.
+
+        If there is only one possible completion for the characters entered, a
+        tab will supply that completion without opening the ACW.
+
+        'Show Completions' will force open a completions window, by default the
+        Control-space keys will open a completions window.  In an empty
+        string, this will contain the files in the current directory.  On a
+        blank line, it will contain the built-in and user-defined functions and
+        classes in the current name spaces, plus any modules imported.  If some
+        characters have been entered, the ACW will attempt to be more specific.
+
+        If string of characters is typed, the ACW selection will jump to the
+        entry most closely matching those characters. Entering a tab will cause
+        the longest non-ambiguous match to be entered in the Edit window or
+        Shell.  Two tabs in a row will supply the current ACW selection, as
+        will return or a double click.  Cursor keys, Page Up/Down, mouse
+        selection, and the scroll wheel all operate on the ACW.
+
+        "Hidden" attributes can be accessed by typing the beginning of hidden
+        name after a '.',  e.g. '_'.  This allows access to modules with
+        '__all__' set, or to class-private attributes.
+
+        Completions and the 'Expand Word' facility can save a lot of typing!
+
+        Completions are currently limited to those in the namespaces.  Names in
+        an Editor window which are not via __main__ or sys.modules will not be
+        found.  Run the module once with your imports to correct this
+        situation.  Note that IDLE itself places quite a few modules in
+        sys.modules, so much can be found by default, e.g. the re module.
+
+        If you don't like the ACW popping up unbidden, simply make the delay
+        longer or disable the extension.  Or another option is the delay could
+        be set to zero. Another alternative to preventing ACW popups is to
+        disable the call tips extension.
+
+Python Shell window:
+
+        Control-c interrupts executing command.
+        Control-d sends end-of-file; closes window if typed at >>> prompt.
+        Alt-/ expand word is also useful to reduce typing.
+
+    Command history:
+
+        Alt-p retrieves previous command matching what you have typed. On OS X
+        use Control-p.
+        Alt-n retrieves next. On OS X use Control-n.
+        Return while cursor is on a previous command retrieves that command.
+
+    Syntax colors:
+
+        The coloring is applied in a background "thread", so you may
+        occasionally see uncolorized text.  To change the color
+        scheme, use the Configure IDLE / Highlighting dialog.
+
+    Python default syntax colors:
+
+        Keywords        orange
+        Builtins        royal purple
+        Strings         green
+        Comments        red
+        Definitions     blue
+
+    Shell default colors:
+
+        Console output  brown
+        stdout          blue
+        stderr          red
+        stdin           black
+
+Other preferences:
+
+        The font preferences, highlighting, keys, and general preferences can
+        be changed via the Configure IDLE menu option.  Be sure to note that
+        keys can be user defined, IDLE ships with four built in key sets. In
+        addition a user can create a custom key set in the Configure IDLE
+        dialog under the keys tab.
+
+Command line usage:
+
+        Enter idle -h at the command prompt to get a usage message.
+
+        idle.py [-c command] [-d] [-e] [-s] [-t title] [arg] ...
+
+        -c command  run this command
+        -d          enable debugger
+        -e          edit mode; arguments are files to be edited
+        -s          run $IDLESTARTUP or $PYTHONSTARTUP first
+        -t title    set title of shell window
+
+        If there are arguments:
+        1. If -e is used, arguments are files opened for editing and sys.argv
+           reflects the arguments passed to IDLE itself.
+        2. Otherwise, if -c is used, all arguments are placed in
+           sys.argv[1:...], with sys.argv[0] set to -c.
+        3. Otherwise, if neither -e nor -c is used, the first argument is a
+           script which is executed with the remaining arguments in
+           sys.argv[1:...]  and sys.argv[0] set to the script name.  If the
+           script name is -, no script is executed but an interactive Python
+           session is started; the arguments are still available in sys.argv.
+
+Running without a subprocess: (DEPRECATED in Python 3.4 see Issue 16123)
+
+        If IDLE is started with the -n command line switch it will run in a
+        single process and will not create the subprocess which runs the RPC
+        Python execution server.  This can be useful if Python cannot create
+        the subprocess or the RPC socket interface on your platform.  However,
+        in this mode user code is not isolated from IDLE itself.  Also, the
+        environment is not restarted when Run/Run Module (F5) is selected.  If
+        your code has been modified, you must reload() the affected modules and
+        re-import any specific items (e.g. from foo import baz) if the changes
+        are to take effect.  For these reasons, it is preferable to run IDLE
+        with the default subprocess if at all possible.
+
+Extensions:
+
+        IDLE contains an extension facility.  See the beginning of
+        config-extensions.def in the idlelib directory for further information.
+        The default extensions are currently:
+
+                FormatParagraph
+                AutoExpand
+                ZoomHeight
+                ScriptBinding
+                CallTips
+                ParenMatch
+                AutoComplete

+README FOR IDLE TESTS IN IDLELIB.IDLE_TEST
+
+
+1. Test Files
+
+The idle directory, idlelib, has over 60 xyz.py files. The idle_test
+subdirectory should contain a test_xyy.py for each. (For test modules, make
+'xyz' lower case, and possibly shorten it.) Each file should start with the
+something like the following template, with the blanks after after '.' and 'as',
+and before and after '_' filled in.
+---
+import unittest
+from test.support import requires
+import idlelib. as
+
+class _Test(unittest.TestCase):
+
+    def test_(self):
+
+if __name__ == '__main__':
+    unittest.main(verbosity=2, exit=2)
+---
+Idle tests are run with unittest; do not use regrtest's test_main.
+
+Once test_xyy is written, the following should go at the end of xyy.py,
+with xyz (lowercased) added after 'test_'.
+---
+if __name__ == "__main__":
+    from test import support; support.use_resources = ['gui']
+    import unittest
+    unittest.main('idlelib.idle_test.test_', verbosity=2, exit=False)
+---
+
+
+2. Gui Tests
+
+Gui tests need 'requires' and 'use_resources' from test.support
+(test.test_support in 2.7). A test is a gui test if it creates a Tk root or
+master object either directly or indirectly by instantiating a tkinter or
+idle class. For the benefit of buildbot machines that do not have a graphics
+screen, gui tests must be 'guarded' by "requires('gui')" in a setUp
+function or method. This will typically be setUpClass.
+
+To avoid interfering with other gui tests, all gui objects must be destroyed
+and deleted by the end of the test.  If a widget, such as a Tk root, is created
+in a setUpX function, destroy it in the corresponding tearDownX.  For module
+and class attributes, also delete the widget.
+---
+    @classmethod
+    def setUpClass(cls):
+        requires('gui')
+        cls.root = tk.Tk()
+
+    @classmethod
+    def tearDownClass(cls):
+        cls.root.destroy()
+        del cls.root
+---
+
+Support.requires('gui') returns true if it is either called in a main module
+(which never happens on buildbots) or if use_resources contains 'gui'.
+Use_resources is set by test.regrtest but not by unittest. So when running
+tests in another module with unittest, we set it ourselves, as in the xyz.py
+template above.
+
+Since non-gui tests always run, but gui tests only sometimes, tests of non-gui
+operations should best avoid needing a gui. Methods that make incidental use of
+tkinter (tk) variables and messageboxes can do this by using the mock classes in
+idle_test/mock_tk.py. There is also a mock text that will handle some uses of the
+tk Text widget.
+
+
+3. Running Tests
+
+Assume that xyz.py and test_xyz.py end with the "if __name__" statements given
+above. In Idle, pressing F5 in an editor window with either loaded will run all
+tests in the test_xyz file with the version of Python running Idle.  The test
+report and any tracebacks will appear in the Shell window. The options in these
+"if __name__" statements are appropriate for developers running (as opposed to
+importing) either of the files during development: verbosity=2 lists all test
+methods in the file; exit=False avoids a spurious sys.exit traceback that would
+otherwise occur when running in Idle. The following command lines also run
+all test methods, including gui tests, in test_xyz.py. (The exceptions are that
+idlelib and idlelib.idle start Idle and idlelib.PyShell should (issue 18330).)
+
+python -m idlelib.xyz  # With the capitalization of the xyz module
+python -m idlelib.idle_test.test_xyz
+
+To run all idle_test/test_*.py tests, either interactively
+('>>>', with unittest imported) or from a command line, use one of the
+following. (Notes: unittest does not run gui tests; in 2.7, 'test ' (with the
+space) is 'test.regrtest '; where present, -v and -ugui can be omitted.)
+
+>>> unittest.main('idlelib.idle_test', verbosity=2, exit=False)
+python -m unittest -v idlelib.idle_test
+python -m test -v -ugui test_idle
+python -m test.test_idle
+
+The idle tests are 'discovered' by idlelib.idle_test.__init__.load_tests,
+which is also imported into test.test_idle. Normally, neither file should be
+changed when working on individual test modules. The third command runs runs
+unittest indirectly through regrtest. The same happens when the entire test
+suite is run with 'python -m test'. So that command must work for buildbots
+to stay green. Idle tests must not disturb the environment in a way that
+makes other tests fail (issue 18081).
+
+To run an individual Testcase or test method, extend the dotted name given to
+unittest on the command line. (But gui tests will not this way.)
+
+python -m unittest -v idlelib.idle_test.test_xyz.Test_case.test_meth

+r"""JSON (JavaScript Object Notation) <http://json.org> is a subset of
+JavaScript syntax (ECMA-262 3rd edition) used as a lightweight data
+interchange format.
+
+:mod:`json` exposes an API familiar to users of the standard library
+:mod:`marshal` and :mod:`pickle` modules.  It is derived from a
+version of the externally maintained simplejson library.
+
+Encoding basic Python object hierarchies::
+
+    >>> import json
+    >>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
+    '["foo", {"bar": ["baz", null, 1.0, 2]}]'
+    >>> print(json.dumps("\"foo\bar"))
+    "\"foo\bar"
+    >>> print(json.dumps('\u1234'))
+    "\u1234"
+    >>> print(json.dumps('\\'))
+    "\\"
+    >>> print(json.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True))
+    {"a": 0, "b": 0, "c": 0}
+    >>> from io import StringIO
+    >>> io = StringIO()
+    >>> json.dump(['streaming API'], io)
+    >>> io.getvalue()
+    '["streaming API"]'
+
+Compact encoding::
+
+    >>> import json
+    >>> from collections import OrderedDict
+    >>> mydict = OrderedDict([('4', 5), ('6', 7)])
+    >>> json.dumps([1,2,3,mydict], separators=(',', ':'))
+    '[1,2,3,{"4":5,"6":7}]'
+
+Pretty printing::
+
+    >>> import json
+    >>> print(json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=4))
+    {
+        "4": 5,
+        "6": 7
+    }
+
+Decoding JSON::
+
+    >>> import json
+    >>> obj = ['foo', {'bar': ['baz', None, 1.0, 2]}]
+    >>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]') == obj
+    True
+    >>> json.loads('"\\"foo\\bar"') == '"foo\x08ar'
+    True
+    >>> from io import StringIO
+    >>> io = StringIO('["streaming API"]')
+    >>> json.load(io)[0] == 'streaming API'
+    True
+
+Specializing JSON object decoding::
+
+    >>> import json
+    >>> def as_complex(dct):
+    ...     if '__complex__' in dct:
+    ...         return complex(dct['real'], dct['imag'])
+    ...     return dct
+    ...
+    >>> json.loads('{"__complex__": true, "real": 1, "imag": 2}',
+    ...     object_hook=as_complex)
+    (1+2j)
+    >>> from decimal import Decimal
+    >>> json.loads('1.1', parse_float=Decimal) == Decimal('1.1')
+    True
+
+Specializing JSON object encoding::
+
+    >>> import json
+    >>> def encode_complex(obj):
+    ...     if isinstance(obj, complex):
+    ...         return [obj.real, obj.imag]
+    ...     raise TypeError(repr(o) + " is not JSON serializable")
+    ...
+    >>> json.dumps(2 + 1j, default=encode_complex)

+
+generate_tokens(readline) is a generator that breaks a stream of
+text into Python tokens.  It accepts a readline-like method which is called
+repeatedly to get the next line of input (or "" for EOF).  It generates
+5-tuples with these members:
+
+    the token type (see token.py)
+    the token (a string)
+    the starting (row, column) indices of the token (a 2-tuple of ints)
+    the ending (row, column) indices of the token (a 2-tuple of ints)
+    the original line (string)
+
+It is designed to match the working of the Python tokenizer exactly, except
+that it produces COMMENT tokens for comments and gives type OP for all
+operators
+
+Older entry points
+    tokenize_loop(readline, tokeneater)
+    tokenize(readline, tokeneater=printtoken)
+are the same, except instead of generating tokens, tokeneater is a callback
+function to which the 5 fields described above are passed as 5 arguments,
+each time a new token is found."""

+
+    Formatters need to know how a LogRecord is constructed. They are

+    be interpreted by either a human or an external system. The base Formatter
+    allows a formatting string to be specified. If none is supplied, the
+    default value of "%s(message)" is used.
+
+    The Formatter can be initialized with a format string which makes use of
+    knowledge of the LogRecord attributes - e.g. the default value mentioned
+    above makes use of the fact that the user's message and arguments are pre-
+    formatted into a LogRecord's message attribute. Currently, the useful
+    attributes in a LogRecord are described by:
+
+    %(name)s            Name of the logger (logging channel)
+    %(levelno)s         Numeric logging level for the message (DEBUG, INFO,

+                        call was issued (if available)
+    %(filename)s        Filename portion of pathname

+
+    This function does nothing if the root logger already has handlers

+    to do one-shot configuration of the logging package.
+
+    The default behaviour is to create a StreamHandler which writes to
+    sys.stderr, set a formatter using the BASIC_FORMAT format string, and
+    add the handler to the root logger.
+
+    A number of optional keyword arguments may be specified, which can alter
+    the default behaviour.
+
+    filename  Specifies that a FileHandler be created, using the specified
+              filename, rather than a StreamHandler.
+    filemode  Specifies the mode to open the file, if filename is specified
+              (if filemode is unspecified, it defaults to 'a').
+    format    Use the specified format string for the handler.
+    datefmt   Use the specified date/time format.
+    style     If a format string is specified, use this to specify the
+              type of format string (possible values '%', '{', '$', for
+              %-formatting, :meth:`str.format` and :class:`string.Template`
+              - defaults to '%').
+    level     Set the root logger level to the specified level.
+    stream    Use the specified stream to initialize the StreamHandler. Note
+              that this argument is incompatible with 'filename' - if both
+              are present, 'stream' is ignored.
+    handlers  If specified, this should be an iterable of already created
+              handlers, which will be added to the root handler. Any handler
+              in the list which does not have a formatter assigned will be
+              assigned the formatter created in this function.
+
+    Note that you could specify a stream created using open(filename, mode)
+    rather than passing the filename and mode in. However, it should be
+    remembered that StreamHandler does not close its stream (since it may be
+    using sys.stdout or sys.stderr), whereas FileHandler closes its stream
+    when the handler is closed.

-    # the only portable, reliable way to find message delimiters in a BSD (i.e
-    # Unix mailbox) style folder is to search for "\n\nFrom .*\n", or at the
-    # beginning of the file, "^From .*\n".  While _fromlinepattern below seems

-    # "From ".
-    #
-    # This algorithm, and the way it interacts with _search_start() and

-    # that the two characters preceding "From " are \n\n or the beginning of

+
+Example:
+
+>>> from nntplib import NNTP
+>>> s = NNTP('news')
+>>> resp, count, first, last, name = s.group('comp.lang.python')
+>>> print('Group', name, 'has', count, 'articles, range', first, 'to', last)

+Here 'resp' is the server response line.
+Error responses are turned into exceptions.

+# RFC 977 by Brian Kantor and Phil Lapsley.
+# xover, xgtitle, xpath, date methods by Kevan Heydon
+
+# Incompatible changes from the 2.x nntplib:
+# - all commands are encoded as UTF-8 data (using the "surrogateescape"
+#   error handler), except for raw message data (POST, IHAVE)
+# - all responses are decoded as UTF-8 data (using the "surrogateescape"
+#   error handler), except for raw message data (ARTICLE, HEAD, BODY)
+# - the `file` argument to various methods is keyword-only
+#
+# - NNTP.date() returns a datetime object
+# - NNTP.newgroups() and NNTP.newnews() take a datetime (or date) object,
+#   rather than a pair of (date, time) strings.
+# - NNTP.newgroups() and NNTP.list() return a list of GroupInfo named tuples
+# - NNTP.descriptions() returns a dict mapping group names to descriptions
+# - NNTP.xover() returns a list of dicts mapping field names (header or metadata)
+#   to field values; each dict representing a message overview.
+# - NNTP.article(), NNTP.head() and NNTP.body() return a (response, ArticleInfo)
+#   tuple.
+# - the "internal" methods have been marked private (they now start with
+#   an underscore)
+
+# Other changes from the 2.x/3.1 nntplib:
+# - automatic querying of capabilities at connect
+# - New method NNTP.getcapabilities()
+# - New method NNTP.over()
+# - New helper function decode_header()
+# - NNTP.post() and NNTP.ihave() accept file objects, bytes-like objects and
+#   arbitrary iterables yielding lines.
+# - An extensive test suite :-)

+r"""OS routines for Mac, NT, or Posix depending on what system we're on.
+
+This exports:
+  - all functions from posix, nt or ce, e.g. unlink, stat, etc.
+  - os.path is either posixpath or ntpath
+  - os.name is either 'posix', 'nt' or 'ce'.
+  - os.curdir is a string representing the current directory ('.' or ':')
+  - os.pardir is a string representing the parent directory ('..' or '::')
+  - os.sep is the (or a most common) pathname separator ('/' or ':' or '\\')
+  - os.extsep is the extension separator (always '.')
+  - os.altsep is the alternate pathname separator (None or '/')
+  - os.pathsep is the component separator used in $PATH etc
+  - os.linesep is the line separator in text files ('\r' or '\n' or '\r\n')
+  - os.defpath is the default search path for executables
+  - os.devnull is the file path of the null device ('/dev/null', etc.)
+
+Programs that import and use 'os' stand a better chance of being
+portable between different platforms.  Of course, they must then
+only use functions that are defined by all platforms (e.g., unlink
+and opendir), and leave all pathname manipulation to os.path
+(e.g., split and join).

+
+    For each directory in the directory tree rooted at top (including top
+    itself, but excluding '.' and '..'), yields a 3-tuple
+
+        dirpath, dirnames, filenames
+
+    dirpath is a string, the path to the directory.  dirnames is a list of
+    the names of the subdirectories in dirpath (excluding '.' and '..').
+    filenames is a list of the names of the non-directory files in dirpath.
+    Note that the names in the lists are just names, with no path components.
+    To get a full path (which begins with top) to a file or directory in
+    dirpath, do os.path.join(dirpath, name).
+
+    If optional arg 'topdown' is true or not specified, the triple for a
+    directory is generated before the triples for any of its subdirectories
+    (directories are generated top down).  If topdown is false, the triple
+    for a directory is generated after the triples for all of its
+    subdirectories (directories are generated bottom up).
+
+    When topdown is true, the caller can modify the dirnames list in-place
+    (e.g., via del or slice assignment), and walk will only recurse into the
+    subdirectories whose names remain in dirnames; this can be used to prune
+    the search, or to impose a specific order of visiting.  Modifying
+    dirnames when topdown is false is ineffective, since the directories in
+    dirnames have already been generated by the time dirnames itself is
+    generated.
+
+    By default errors from the os.listdir() call are ignored.  If
+    optional arg 'onerror' is specified, it should be a function; it
+    will be called with one argument, an OSError instance.  It can
+    report the error to continue with the walk, or raise the exception
+    to abort the walk.  Note that the filename is available as the
+    filename attribute of the exception object.
+
+    By default, os.walk does not follow symbolic links to subdirectories on
+    systems that support them.  In order to get this functionality, set the
+    optional argument 'followlinks' to true.
+
+    Caution:  if you pass a relative pathname for top, don't change the
+    current working directory between resumptions of walk.  walk never
+    changes the current directory, and assumes that the client doesn't
+    either.
+

+The Python Debugger Pdb
+=======================
+
+To use the debugger in its simplest form:
+
+        >>> import pdb
+        >>> pdb.run('<a statement>')
+
+The debugger's prompt is '(Pdb) '.  This will stop in the first
+function call in <a statement>.
+
+Alternatively, if a statement terminated with an unhandled exception,
+you can use pdb's post-mortem facility to inspect the contents of the
+traceback:
+
+        >>> <a statement>
+        <exception traceback>
+        >>> import pdb
+        >>> pdb.pm()
+
+The commands recognized by the debugger are listed in the next
+section.  Most can be abbreviated as indicated; e.g., h(elp) means
+that 'help' can be typed as 'h' or 'help' (but not as 'he' or 'hel',
+nor as 'H' or 'Help' or 'HELP').  Optional arguments are enclosed in
+square brackets.  Alternatives in the command syntax are separated
+by a vertical bar (|).
+
+A blank line repeats the previous command literally, except for
+'list', where it lists the next 11 lines.
+
+Commands that the debugger doesn't recognize are assumed to be Python
+statements and are executed in the context of the program being
+debugged.  Python statements can also be prefixed with an exclamation
+point ('!').  This is a powerful way to inspect the program being
+debugged; it is even possible to change variables or call functions.
+When an exception occurs in such a statement, the exception name is
+printed but the debugger's state is not changed.
+
+The debugger supports aliases, which can save typing.  And aliases can
+have parameters (see the alias help entry) which allows one a certain
+level of adaptability to the context under examination.
+
+Multiple commands may be entered on a single line, separated by the
+pair ';;'.  No intelligence is applied to separating the commands; the
+input is split at the first ';;', even if it is in the middle of a
+quoted string.
+
+If a file ".pdbrc" exists in your home directory or in the current
+directory, it is read in and executed as if it had been typed at the
+debugger prompt.  This is particularly useful for aliases.  If both
+files exist, the one in the home directory is read first and aliases
+defined there can be overriden by the local file.
+
+Aside from aliases, the debugger is not directly programmable; but it
+is implemented as a class from which you can derive your own debugger
+class, which you can make as fancy as you like.

+Extensive comments about the pickle protocols and pickle-machine opcodes

+
+genops(pickle)
+   Generate all the opcodes in a pickle, as (opcode, arg, position) triples.
+
+dis(pickle, out=None, memo=None, indentlevel=4)
+   Print a symbolic disassembly of a pickle.

+
+# Other ideas:
+#
+# - A pickle verifier:  read a pickle and check it exhaustively for
+#   well-formedness.  dis() does a lot of this already.
+#
+# - A protocol identifier:  examine a pickle and return its protocol number
+#   (== the highest .proto attr value among all the opcodes in the pickle).
+#   dis() already prints this info at the end.
+#
+# - A pickle optimizer:  for example, tuple-building code is sometimes more
+#   elaborate than necessary, catering for the possibility that the tuple
+#   is recursive.  Or lots of times a PUT is generated that's never accessed
+#   by a later GET.
+
+
+# "A pickle" is a program for a virtual pickle machine (PM, but more accurately
+# called an unpickling machine).  It's a sequence of opcodes, interpreted by the
+# PM, building an arbitrarily complex Python object.
+#
+# For the most part, the PM is very simple:  there are no looping, testing, or
+# conditional instructions, no arithmetic and no function calls.  Opcodes are
+# executed once each, from first to last, until a STOP opcode is reached.
+#
+# The PM has two data areas, "the stack" and "the memo".
+#
+# Many opcodes push Python objects onto the stack; e.g., INT pushes a Python
+# integer object on the stack, whose value is gotten from a decimal string
+# literal immediately following the INT opcode in the pickle bytestream.  Other
+# opcodes take Python objects off the stack.  The result of unpickling is
+# whatever object is left on the stack when the final STOP opcode is executed.
+#
+# The memo is simply an array of objects, or it can be implemented as a dict
+# mapping little integers to objects.  The memo serves as the PM's "long term
+# memory", and the little integers indexing the memo are akin to variable
+# names.  Some opcodes pop a stack object into the memo at a given index,
+# and others push a memo object at a given index onto the stack again.
+#
+# At heart, that's all the PM has.  Subtleties arise for these reasons:
+#
+# + Object identity.  Objects can be arbitrarily complex, and subobjects
+#   may be shared (for example, the list [a, a] refers to the same object a
+#   twice).  It can be vital that unpickling recreate an isomorphic object
+#   graph, faithfully reproducing sharing.
+#
+# + Recursive objects.  For example, after "L = []; L.append(L)", L is a
+#   list, and L[0] is the same list.  This is related to the object identity
+#   point, and some sequences of pickle opcodes are subtle in order to
+#   get the right result in all cases.
+#
+# + Things pickle doesn't know everything about.  Examples of things pickle
+#   does know everything about are Python's builtin scalar and container
+#   types, like ints and tuples.  They generally have opcodes dedicated to
+#   them.  For things like module references and instances of user-defined
+#   classes, pickle's knowledge is limited.  Historically, many enhancements
+#   have been made to the pickle protocol in order to do a better (faster,
+#   and/or more compact) job on those.
+#
+# + Backward compatibility and micro-optimization.  As explained below,
+#   pickle opcodes never go away, not even when better ways to do a thing
+#   get invented.  The repertoire of the PM just keeps growing over time.
+#   For example, protocol 0 had two opcodes for building Python integers (INT
+#   and LONG), protocol 1 added three more for more-efficient pickling of short
+#   integers, and protocol 2 added two more for more-efficient pickling of
+#   long integers (before protocol 2, the only ways to pickle a Python long
+#   took time quadratic in the number of digits, for both pickling and
+#   unpickling).  "Opcode bloat" isn't so much a subtlety as a source of
+#   wearying complication.
+#
+#
+# Pickle protocols:
+#
+# For compatibility, the meaning of a pickle opcode never changes.  Instead new
+# pickle opcodes get added, and each version's unpickler can handle all the
+# pickle opcodes in all protocol versions to date.  So old pickles continue to
+# be readable forever.  The pickler can generally be told to restrict itself to
+# the subset of opcodes available under previous protocol versions too, so that
+# users can create pickles under the current version readable by older
+# versions.  However, a pickle does not contain its version number embedded
+# within it.  If an older unpickler tries to read a pickle using a later
+# protocol, the result is most likely an exception due to seeing an unknown (in
+# the older unpickler) opcode.
+#
+# The original pickle used what's now called "protocol 0", and what was called
+# "text mode" before Python 2.3.  The entire pickle bytestream is made up of
+# printable 7-bit ASCII characters, plus the newline character, in protocol 0.
+# That's why it was called text mode.  Protocol 0 is small and elegant, but
+# sometimes painfully inefficient.
+#
+# The second major set of additions is now called "protocol 1", and was called
+# "binary mode" before Python 2.3.  This added many opcodes with arguments
+# consisting of arbitrary bytes, including NUL bytes and unprintable "high bit"
+# bytes.  Binary mode pickles can be substantially smaller than equivalent
+# text mode pickles, and sometimes faster too; e.g., BININT represents a 4-byte
+# int as 4 bytes following the opcode, which is cheaper to unpickle than the
+# (perhaps) 11-character decimal string attached to INT.  Protocol 1 also added
+# a number of opcodes that operate on many stack elements at once (like APPENDS
+# and SETITEMS), and "shortcut" opcodes (like EMPTY_DICT and EMPTY_TUPLE).
+#
+# The third major set of additions came in Python 2.3, and is called "protocol
+# 2".  This added:
+#
+# - A better way to pickle instances of new-style classes (NEWOBJ).
+#
+# - A way for a pickle to identify its protocol (PROTO).
+#
+# - Time- and space- efficient pickling of long ints (LONG{1,4}).
+#
+# - Shortcuts for small tuples (TUPLE{1,2,3}}.
+#
+# - Dedicated opcodes for bools (NEWTRUE, NEWFALSE).
+#
+# - The "extension registry", a vector of popular objects that can be pushed
+#   efficiently by index (EXT{1,2,4}).  This is akin to the memo and GET, but
+#   the registry contents are predefined (there's nothing akin to the memo's
+#   PUT).
+#
+# Another independent change with Python 2.3 is the abandonment of any
+# pretense that it might be safe to load pickles received from untrusted
+# parties -- no sufficient security analysis has been done to guarantee
+# this and there isn't a use case that warrants the expense of such an
+# analysis.
+#
+# To this end, all tests for __safe_for_unpickling__ or for
+# copyreg.safe_constructors are removed from the unpickling code.
+# References to these variables in the descriptions below are to be seen
+# as describing unpickling in Python 2.2 and before.
+
+
+# Meta-rule:  Descriptions are stored in instances of descriptor objects,
+# with plain constructors.  No meta-language is defined from which
+# descriptors could be constructed.  If you want, e.g., XML, write a little
+# program to generate XML from the objects.

+
+    'pickle' is a file-like object, or string, containing a (at least one)
+    pickle.  The pickle is disassembled from the current position, through
+    the first STOP opcode encountered.
+
+    Optional arg 'out' is a file-like object to which the disassembly is
+    printed.  It defaults to sys.stdout.
+
+    Optional arg 'memo' is a Python dict, used as the pickle's memo.  It
+    may be mutated by dis(), if the pickle contains PUT or BINPUT opcodes.
+    Passing the same memo object to another dis() call then allows disassembly
+    to proceed across multiple pickles that were all created by the same
+    pickler with the same memo.  Ordinarily you don't need to worry about this.
+
+    Optional arg 'indentlevel' is the number of blanks by which to indent
+    a new MARK level.  It defaults to 4.
+
+    Optional arg 'annotate' if nonzero instructs dis() to add short
+    description of the opcode on each line of disassembled output.
+    The value given to 'annotate' must be an integer and is used as a
+    hint for the column where annotation should start.  The default
+    value is 0, meaning no annotations.
+
+    In addition to printing the disassembly, some sanity checks are made:
+
+    + All embedded opcode arguments "make sense".
+
+    + Explicit and implicit pop operations have enough items on the stack.

+""" This module tries to retrieve as much platform-identifying data as
+    possible. It makes this information available via function APIs.
+
+    If called from the command line, it prints the platform
+    information concatenated as single string to stdout. The output
+    format is useable as part of a filename.

+#    * support for Amiga and other still unsupported platforms running Python

+#    History:
+#
+#    <see CVS and SVN checkin messages for history>
+#
+#    1.0.7 - added DEV_NULL
+#    1.0.6 - added linux_distribution()
+#    1.0.5 - fixed Java support to allow running the module on Jython
+#    1.0.4 - added IronPython support
+#    1.0.3 - added normalization of Windows system name
+#    1.0.2 - added more Windows support
+#    1.0.1 - reformatted to make doc.py happy
+#    1.0.0 - reformatted a bit and checked into Python CVS
+#    0.8.0 - added sys.version parser and various new access
+#            APIs (python_version(), python_compiler(), etc.)
+#    0.7.2 - fixed architecture() to use sizeof(pointer) where available
+#    0.7.1 - added support for Caldera OpenLinux
+#    0.7.0 - some fixes for WinCE; untabified the source file
+#    0.6.2 - support for OpenVMS - requires version 1.5.2-V006 or higher and
+#            vms_lib.getsyi() configured
+#    0.6.1 - added code to prevent 'uname -p' on platforms which are
+#            known not to support it
+#    0.6.0 - fixed win32_ver() to hopefully work on Win95,98,NT and Win2k;
+#            did some cleanup of the interfaces - some APIs have changed
+#    0.5.5 - fixed another type in the MacOS code... should have
+#            used more coffee today ;-)
+#    0.5.4 - fixed a few typos in the MacOS code
+#    0.5.3 - added experimental MacOS support; added better popen()
+#            workarounds in _syscmd_ver() -- still not 100% elegant
+#            though
+#    0.5.2 - fixed uname() to return '' instead of 'unknown' in all
+#            return values (the system uname command tends to return
+#            'unknown' instead of just leaving the field emtpy)
+#    0.5.1 - included code for slackware dist; added exception handlers
+#            to cover up situations where platforms don't have os.popen
+#            (e.g. Mac) or fail on socket.gethostname(); fixed libc
+#            detection RE
+#    0.5.0 - changed the API names referring to system commands to *syscmd*;
+#            added java_ver(); made syscmd_ver() a private
+#            API (was system_ver() in previous versions) -- use uname()
+#            instead; extended the win32_ver() to also return processor
+#            type information
+#    0.4.0 - added win32_ver() and modified the platform() output for WinXX
+#    0.3.4 - fixed a bug in _follow_symlinks()
+#    0.3.3 - fixed popen() and "file" command invokation bugs
+#    0.3.2 - added architecture() API and support for it in platform()
+#    0.3.1 - fixed syscmd_ver() RE to support Windows NT
+#    0.3.0 - added system alias support
+#    0.2.3 - removed 'wince' again... oh well.
+#    0.2.2 - added 'wince' to syscmd_ver() supported platforms
+#    0.2.1 - added cache logic and changed the platform string format
+#    0.2.0 - changed the API to use functions instead of module globals
+#            since some action take too long to be run on module import
+#    0.1.0 - first release

+r"""plistlib.py -- a tool to generate and parse MacOSX .plist files.
+
+The property list (.plist) file format is a simple XML pickle supporting
+basic object types, like dictionaries, lists, numbers and strings.
+Usually the top level object is a dictionary.
+
+To write out a plist file, use the dump(value, file)
+function. 'value' is the top level object, 'file' is
+a (writable) file object.
+
+To parse a plist from a file, use the load(file) function,
+with a (readable) file object as the only argument. It
+returns the top level object (again, usually a dictionary).
+
+To work with plist data in bytes objects, you can use loads()
+and dumps().
+
+Values can be strings, integers, floats, booleans, tuples, lists,
+dictionaries (but only with string keys), Data, bytes, bytearray, or
+datetime.datetime objects.
+
+Generate Plist example:
+
+    pl = dict(
+        aString = "Doodah",
+        aList = ["A", "B", 12, 32.1, [1, 2, 3]],
+        aFloat = 0.1,
+        anInt = 728,
+        aDict = dict(
+            anotherString = "<hello & hi there!>",

+class POP3:
+
+    """This class supports both the minimal and optional command sets.
+    Arguments can be strings or integers (where appropriate)
+    (e.g.: retr(1) and retr('1') both work equally well.
+
+    Minimal Command Set:
+            USER name               user(name)
+            PASS string             pass_(string)

+            LIST [msg]              list(msg = None)
+            RETR msg                retr(msg)
+            DELE msg                dele(msg)
+            NOOP                    noop()
+            RSET                    rset()
+            QUIT                    quit()
+
+    Optional Commands (some servers support these):
+            RPOP name               rpop(name)
+            APOP name digest        apop(name, digest)
+            TOP msg n               top(msg, n)
+            UIDL [msg]              uidl(msg = None)
+            CAPA                    capa()
+            STLS                    stls()
+
+    Raises one exception: 'error_proto'.
+
+    Instantiate with:
+            POP3(hostname, port=110)
+
+    NB:     the POP protocol locks the mailbox from user
+            authorization until QUIT, so be sure to get in, suck
+            the messages, and quit, each time you access the
+            mailbox.
+
+            POP is a line-based protocol, which means large mail
+            messages consume lots of python cycles reading them
+            line-by-line.
+
+            If it's available on your mail server, use IMAP4
+            instead, it doesn't suffer from the two problems
+            above.

+class Stats:
+    """This class is used for creating reports from data generated by the
+    Profile class.  It is a "friend" of that class, and imports data either
+    by direct access to members of Profile class, or by reading in a dictionary
+    that was emitted (via marshal) from the Profile class.
+
+    The big change from the previous Profiler (in terms of raw functionality)
+    is that an "add()" method has been provided to combine Stats from
+    several distinct profile runs.  Both the constructor and the add()
+    method now take arbitrarily many file names as arguments.
+
+    All the print methods now take an argument that indicates how many lines
+    to print.  If the arg is a floating point number between 0 and 1.0, then
+    it is taken as a decimal percentage of the available lines to be printed
+    (e.g., .1 means print 10% of all available lines).  If it is an integer,
+    it is taken to mean the number of lines of data that you wish to have
+    printed.
+
+    The sort_stats() method now processes some additional options (i.e., in
+    addition to the old -1, 0, 1, or 2).  It takes an arbitrary number of
+    quoted strings to select the sort order.  For example sort_stats('time',
+    'name') sorts on the major key of 'internal function time', and on the
+    minor key of 'the name of the function'.  Look at the two tables in
+    sort_stats() and get_sort_arg_defs(self) for more examples.
+
+    All methods return self, so you can string together commands like:
+        Stats('foo', 'goo').strip_dirs().sort_stats('calls').\

+    and thus they won't be able to write the .pyc/.pyo file, and then
+    they would be byte-compiling every module each time it is loaded.

+topics = {'assert': '\nThe "assert" statement\n**********************\n\nAssert statements are a convenient way to insert debugging assertions\ninto a program:\n\n   assert_stmt ::= "assert" expression ["," expression]\n\nThe simple form, "assert expression", is equivalent to\n\n   if __debug__:\n      if not expression: raise AssertionError\n\nThe extended form, "assert expression1, expression2", is equivalent to\n\n   if __debug__:\n      if not expression1: raise AssertionError(expression2)\n\nThese equivalences assume that "__debug__" and "AssertionError" refer\nto the built-in variables with those names.  In the current\nimplementation, the built-in variable "__debug__" is "True" under\nnormal circumstances, "False" when optimization is requested (command\nline option -O).  The current code generator emits no code for an\nassert statement when optimization is requested at compile time.  Note\nthat it is unnecessary to include the source code for the expression\nthat failed in the error message; it will be displayed as part of the\nstack trace.\n\nAssignments to "__debug__" are illegal.  The value for the built-in\nvariable is determined when the interpreter starts.\n',
+ 'assignment': '\nAssignment statements\n*********************\n\nAssignment statements are used to (re)bind names to values and to\nmodify attributes or items of mutable objects:\n\n   assignment_stmt ::= (target_list "=")+ (expression_list | yield_expression)\n   target_list     ::= target ("," target)* [","]\n   target          ::= identifier\n              | "(" target_list ")"\n              | "[" target_list "]"\n              | attributeref\n              | subscription\n              | slicing\n              | "*" target\n\n(See section *Primaries* for the syntax definitions for the last three\nsymbols.)\n\nAn assignment statement evaluates the expression list (remember that\nthis can be a single expression or a comma-separated list, the latter\nyielding a tuple) and assigns the single resulting object to each of\nthe target lists, from left to right.\n\nAssignment is defined recursively depending on the form of the target\n(list). When a target is part of a mutable object (an attribute\nreference, subscription or slicing), the mutable object must\nultimately perform the assignment and decide about its validity, and\nmay raise an exception if the assignment is unacceptable.  The rules\nobserved by various types and the exceptions raised are given with the\ndefinition of the object types (see section *The standard type\nhierarchy*).\n\nAssignment of an object to a target list, optionally enclosed in\nparentheses or square brackets, is recursively defined as follows.\n\n* If the target list is a single target: The object is assigned to\n  that target.\n\n* If the target list is a comma-separated list of targets: The object\n  must be an iterable with the same number of items as there are\n  targets in the target list, and the items are assigned, from left to\n  right, to the corresponding targets.\n\n  * If the target list contains one target prefixed with an asterisk,\n    called a "starred" target: The object must be a sequence with at\n    least as many items as there are targets in the target list, minus\n    one.  The first items of the sequence are assigned, from left to\n    right, to the targets before the starred target.  The final items\n    of the sequence are assigned to the targets after the starred\n    target.  A list of the remaining items in the sequence is then\n    assigned to the starred target (the list can be empty).\n\n  * Else: The object must be a sequence with the same number of items\n    as there are targets in the target list, and the items are\n    assigned, from left to right, to the corresponding targets.\n\nAssignment of an object to a single target is recursively defined as\nfollows.\n\n* If the target is an identifier (name):\n\n  * If the name does not occur in a "global" or "nonlocal" statement\n    in the current code block: the name is bound to the object in the\n    current local namespace.\n\n  * Otherwise: the name is bound to the object in the global namespace\n    or the outer namespace determined by "nonlocal", respectively.\n\n  The name is rebound if it was already bound.  This may cause the\n  reference count for the object previously bound to the name to reach\n  zero, causing the object to be deallocated and its destructor (if it\n  has one) to be called.\n\n* If the target is a target list enclosed in parentheses or in square\n  brackets: The object must be an iterable with the same number of\n  items as there are targets in the target list, and its items are\n  assigned, from left to right, to the corresponding targets.\n\n* If the target is an attribute reference: The primary expression in\n  the reference is evaluated.  It should yield an object with\n  assignable attributes; if this is not the case, "TypeError" is\n  raised.  That object is then asked to assign the assigned object to\n  the given attribute; if it cannot perform the assignment, it raises\n  an exception (usually but not necessarily "AttributeError").\n\n  Note: If the object is a class instance and the attribute reference\n  occurs on both sides of the assignment operator, the RHS expression,\n  "a.x" can access either an instance attribute or (if no instance\n  attribute exists) a class attribute.  The LHS target "a.x" is always\n  set as an instance attribute, creating it if necessary.  Thus, the\n  two occurrences of "a.x" do not necessarily refer to the same\n  attribute: if the RHS expression refers to a class attribute, the\n  LHS creates a new instance attribute as the target of the\n  assignment:\n\n     class Cls:\n         x = 3             # class variable\n     inst = Cls()\n     inst.x = inst.x + 1   # writes inst.x as 4 leaving Cls.x as 3\n\n  This description does not necessarily apply to descriptor\n  attributes, such as properties created with "property()".\n\n* If the target is a subscription: The primary expression in the\n  reference is evaluated.  It should yield either a mutable sequence\n  object (such as a list) or a mapping object (such as a dictionary).\n  Next, the subscript expression is evaluated.\n\n  If the primary is a mutable sequence object (such as a list), the\n  subscript must yield an integer.  If it is negative, the sequence\'s\n  length is added to it.  The resulting value must be a nonnegative\n  integer less than the sequence\'s length, and the sequence is asked\n  to assign the assigned object to its item with that index.  If the\n  index is out of range, "IndexError" is raised (assignment to a\n  subscripted sequence cannot add new items to a list).\n\n  If the primary is a mapping object (such as a dictionary), the\n  subscript must have a type compatible with the mapping\'s key type,\n  and the mapping is then asked to create a key/datum pair which maps\n  the subscript to the assigned object.  This can either replace an\n  existing key/value pair with the same key value, or insert a new\n  key/value pair (if no key with the same value existed).\n\n  For user-defined objects, the "__setitem__()" method is called with\n  appropriate arguments.\n\n* If the target is a slicing: The primary expression in the reference\n  is evaluated.  It should yield a mutable sequence object (such as a\n  list).  The assigned object should be a sequence object of the same\n  type.  Next, the lower and upper bound expressions are evaluated,\n  insofar they are present; defaults are zero and the sequence\'s\n  length.  The bounds should evaluate to integers. If either bound is\n  negative, the sequence\'s length is added to it.  The resulting\n  bounds are clipped to lie between zero and the sequence\'s length,\n  inclusive.  Finally, the sequence object is asked to replace the\n  slice with the items of the assigned sequence.  The length of the\n  slice may be different from the length of the assigned sequence,\n  thus changing the length of the target sequence, if the object\n  allows it.\n\n**CPython implementation detail:** In the current implementation, the\nsyntax for targets is taken to be the same as for expressions, and\ninvalid syntax is rejected during the code generation phase, causing\nless detailed error messages.\n\nWARNING: Although the definition of assignment implies that overlaps\nbetween the left-hand side and the right-hand side are \'safe\' (for\nexample "a, b = b, a" swaps two variables), overlaps *within* the\ncollection of assigned-to variables are not safe!  For instance, the\nfollowing program prints "[0, 2]":\n\n   x = [0, 1]\n   i = 0\n   i, x[i] = 1, 2\n   print(x)\n\nSee also:\n\n   **PEP 3132** - Extended Iterable Unpacking\n      The specification for the "*target" feature.\n\n\nAugmented assignment statements\n===============================\n\nAugmented assignment is the combination, in a single statement, of a\nbinary operation and an assignment statement:\n\n   augmented_assignment_stmt ::= augtarget augop (expression_list | yield_expression)\n   augtarget                 ::= identifier | attributeref | subscription | slicing\n   augop                     ::= "+=" | "-=" | "*=" | "/=" | "//=" | "%=" | "**="\n             | ">>=" | "<<=" | "&=" | "^=" | "|="\n\n(See section *Primaries* for the syntax definitions for the last three\nsymbols.)\n\nAn augmented assignment evaluates the target (which, unlike normal\nassignment statements, cannot be an unpacking) and the expression\nlist, performs the binary operation specific to the type of assignment\non the two operands, and assigns the result to the original target.\nThe target is only evaluated once.\n\nAn augmented assignment expression like "x += 1" can be rewritten as\n"x = x + 1" to achieve a similar, but not exactly equal effect. In the\naugmented version, "x" is only evaluated once. Also, when possible,\nthe actual operation is performed *in-place*, meaning that rather than\ncreating a new object and assigning that to the target, the old object\nis modified instead.\n\nWith the exception of assigning to tuples and multiple targets in a\nsingle statement, the assignment done by augmented assignment\nstatements is handled the same way as normal assignments. Similarly,\nwith the exception of the possible *in-place* behavior, the binary\noperation performed by augmented assignment is the same as the normal\nbinary operations.\n\nFor targets which are attribute references, the same *caveat about\nclass and instance attributes* applies as for regular assignments.\n',
+ 'atom-identifiers': '\nIdentifiers (Names)\n*******************\n\nAn identifier occurring as an atom is a name.  See section\n*Identifiers and keywords* for lexical definition and section *Naming\nand binding* for documentation of naming and binding.\n\nWhen the name is bound to an object, evaluation of the atom yields\nthat object. When a name is not bound, an attempt to evaluate it\nraises a "NameError" exception.\n\n**Private name mangling:** When an identifier that textually occurs in\na class definition begins with two or more underscore characters and\ndoes not end in two or more underscores, it is considered a *private\nname* of that class. Private names are transformed to a longer form\nbefore code is generated for them.  The transformation inserts the\nclass name, with leading underscores removed and a single underscore\ninserted, in front of the name.  For example, the identifier "__spam"\noccurring in a class named "Ham" will be transformed to "_Ham__spam".\nThis transformation is independent of the syntactical context in which\nthe identifier is used.  If the transformed name is extremely long\n(longer than 255 characters), implementation defined truncation may\nhappen. If the class name consists only of underscores, no\ntransformation is done.\n',
+ 'atom-literals': "\nLiterals\n********\n\nPython supports string and bytes literals and various numeric\nliterals:\n\n   literal ::= stringliteral | bytesliteral\n               | integer | floatnumber | imagnumber\n\nEvaluation of a literal yields an object of the given type (string,\nbytes, integer, floating point number, complex number) with the given\nvalue.  The value may be approximated in the case of floating point\nand imaginary (complex) literals.  See section *Literals* for details.\n\nAll literals correspond to immutable data types, and hence the\nobject's identity is less important than its value.  Multiple\nevaluations of literals with the same value (either the same\noccurrence in the program text or a different occurrence) may obtain\nthe same object or a different object with the same value.\n",
+ 'attribute-access': '\nCustomizing attribute access\n****************************\n\nThe following methods can be defined to customize the meaning of\nattribute access (use of, assignment to, or deletion of "x.name") for\nclass instances.\n\nobject.__getattr__(self, name)\n\n   Called when an attribute lookup has not found the attribute in the\n   usual places (i.e. it is not an instance attribute nor is it found\n   in the class tree for "self").  "name" is the attribute name. This\n   method should return the (computed) attribute value or raise an\n   "AttributeError" exception.\n\n   Note that if the attribute is found through the normal mechanism,\n   "__getattr__()" is not called.  (This is an intentional asymmetry\n   between "__getattr__()" and "__setattr__()".) This is done both for\n   efficiency reasons and because otherwise "__getattr__()" would have\n   no way to access other attributes of the instance.  Note that at\n   least for instance variables, you can fake total control by not\n   inserting any values in the instance attribute dictionary (but\n   instead inserting them in another object).  See the\n   "__getattribute__()" method below for a way to actually get total\n   control over attribute access.\n\nobject.__getattribute__(self, name)\n\n   Called unconditionally to implement attribute accesses for\n   instances of the class. If the class also defines "__getattr__()",\n   the latter will not be called unless "__getattribute__()" either\n   calls it explicitly or raises an "AttributeError". This method\n   should return the (computed) attribute value or raise an\n   "AttributeError" exception. In order to avoid infinite recursion in\n   this method, its implementation should always call the base class\n   method with the same name to access any attributes it needs, for\n   example, "object.__getattribute__(self, name)".\n\n   Note: This method may still be bypassed when looking up special methods\n     as the result of implicit invocation via language syntax or\n     built-in functions. See *Special method lookup*.\n\nobject.__setattr__(self, name, value)\n\n   Called when an attribute assignment is attempted.  This is called\n   instead of the normal mechanism (i.e. store the value in the\n   instance dictionary). *name* is the attribute name, *value* is the\n   value to be assigned to it.\n\n   If "__setattr__()" wants to assign to an instance attribute, it\n   should call the base class method with the same name, for example,\n   "object.__setattr__(self, name, value)".\n\nobject.__delattr__(self, name)\n\n   Like "__setattr__()" but for attribute deletion instead of\n   assignment.  This should only be implemented if "del obj.name" is\n   meaningful for the object.\n\nobject.__dir__(self)\n\n   Called when "dir()" is called on the object. A sequence must be\n   returned. "dir()" converts the returned sequence to a list and\n   sorts it.\n\n\nImplementing Descriptors\n========================\n\nThe following methods only apply when an instance of the class\ncontaining the method (a so-called *descriptor* class) appears in an\n*owner* class (the descriptor must be in either the owner\'s class\ndictionary or in the class dictionary for one of its parents).  In the\nexamples below, "the attribute" refers to the attribute whose name is\nthe key of the property in the owner class\' "__dict__".\n\nobject.__get__(self, instance, owner)\n\n   Called to get the attribute of the owner class (class attribute\n   access) or of an instance of that class (instance attribute\n   access). *owner* is always the owner class, while *instance* is the\n   instance that the attribute was accessed through, or "None" when\n   the attribute is accessed through the *owner*.  This method should\n   return the (computed) attribute value or raise an "AttributeError"\n   exception.\n\nobject.__set__(self, instance, value)\n\n   Called to set the attribute on an instance *instance* of the owner\n   class to a new value, *value*.\n\nobject.__delete__(self, instance)\n\n   Called to delete the attribute on an instance *instance* of the\n   owner class.\n\nThe attribute "__objclass__" is interpreted by the "inspect" module as\nspecifying the class where this object was defined (setting this\nappropriately can assist in runtime introspection of dynamic class\nattributes). For callables, it may indicate that an instance of the\ngiven type (or a subclass) is expected or required as the first\npositional argument (for example, CPython sets this attribute for\nunbound methods that are implemented in C).\n\n\nInvoking Descriptors\n====================\n\nIn general, a descriptor is an object attribute with "binding\nbehavior", one whose attribute access has been overridden by methods\nin the descriptor protocol:  "__get__()", "__set__()", and\n"__delete__()". If any of those methods are defined for an object, it\nis said to be a descriptor.\n\nThe default behavior for attribute access is to get, set, or delete\nthe attribute from an object\'s dictionary. For instance, "a.x" has a\nlookup chain starting with "a.__dict__[\'x\']", then\n"type(a).__dict__[\'x\']", and continuing through the base classes of\n"type(a)" excluding metaclasses.\n\nHowever, if the looked-up value is an object defining one of the\ndescriptor methods, then Python may override the default behavior and\ninvoke the descriptor method instead.  Where this occurs in the\nprecedence chain depends on which descriptor methods were defined and\nhow they were called.\n\nThe starting point for descriptor invocation is a binding, "a.x". How\nthe arguments are assembled depends on "a":\n\nDirect Call\n   The simplest and least common call is when user code directly\n   invokes a descriptor method:    "x.__get__(a)".\n\nInstance Binding\n   If binding to an object instance, "a.x" is transformed into the\n   call: "type(a).__dict__[\'x\'].__get__(a, type(a))".\n\nClass Binding\n   If binding to a class, "A.x" is transformed into the call:\n   "A.__dict__[\'x\'].__get__(None, A)".\n\nSuper Binding\n   If "a" is an instance of "super", then the binding "super(B,\n   obj).m()" searches "obj.__class__.__mro__" for the base class "A"\n   immediately preceding "B" and then invokes the descriptor with the\n   call: "A.__dict__[\'m\'].__get__(obj, obj.__class__)".\n\nFor instance bindings, the precedence of descriptor invocation depends\non the which descriptor methods are defined.  A descriptor can define\nany combination of "__get__()", "__set__()" and "__delete__()".  If it\ndoes not define "__get__()", then accessing the attribute will return\nthe descriptor object itself unless there is a value in the object\'s\ninstance dictionary.  If the descriptor defines "__set__()" and/or\n"__delete__()", it is a data descriptor; if it defines neither, it is\na non-data descriptor.  Normally, data descriptors define both\n"__get__()" and "__set__()", while non-data descriptors have just the\n"__get__()" method.  Data descriptors with "__set__()" and "__get__()"\ndefined always override a redefinition in an instance dictionary.  In\ncontrast, non-data descriptors can be overridden by instances.\n\nPython methods (including "staticmethod()" and "classmethod()") are\nimplemented as non-data descriptors.  Accordingly, instances can\nredefine and override methods.  This allows individual instances to\nacquire behaviors that differ from other instances of the same class.\n\nThe "property()" function is implemented as a data descriptor.\nAccordingly, instances cannot override the behavior of a property.\n\n\n__slots__\n=========\n\nBy default, instances of classes have a dictionary for attribute\nstorage.  This wastes space for objects having very few instance\nvariables.  The space consumption can become acute when creating large\nnumbers of instances.\n\nThe default can be overridden by defining *__slots__* in a class\ndefinition. The *__slots__* declaration takes a sequence of instance\nvariables and reserves just enough space in each instance to hold a\nvalue for each variable.  Space is saved because *__dict__* is not\ncreated for each instance.\n\nobject.__slots__\n\n   This class variable can be assigned a string, iterable, or sequence\n   of strings with variable names used by instances.  If defined in a\n   class, *__slots__* reserves space for the declared variables and\n   prevents the automatic creation of *__dict__* and *__weakref__* for\n   each instance.\n\n\nNotes on using *__slots__*\n--------------------------\n\n* When inheriting from a class without *__slots__*, the *__dict__*\n  attribute of that class will always be accessible, so a *__slots__*\n  definition in the subclass is meaningless.\n\n* Without a *__dict__* variable, instances cannot be assigned new\n  variables not listed in the *__slots__* definition.  Attempts to\n  assign to an unlisted variable name raises "AttributeError". If\n  dynamic assignment of new variables is desired, then add\n  "\'__dict__\'" to the sequence of strings in the *__slots__*\n  declaration.\n\n* Without a *__weakref__* variable for each instance, classes defining\n  *__slots__* do not support weak references to its instances. If weak\n  reference support is needed, then add "\'__weakref__\'" to the\n  sequence of strings in the *__slots__* declaration.\n\n* *__slots__* are implemented at the class level by creating\n  descriptors (*Implementing Descriptors*) for each variable name.  As\n  a result, class attributes cannot be used to set default values for\n  instance variables defined by *__slots__*; otherwise, the class\n  attribute would overwrite the descriptor assignment.\n\n* The action of a *__slots__* declaration is limited to the class\n  where it is defined.  As a result, subclasses will have a *__dict__*\n  unless they also define *__slots__* (which must only contain names\n  of any *additional* slots).\n\n* If a class defines a slot also defined in a base class, the instance\n  variable defined by the base class slot is inaccessible (except by\n  retrieving its descriptor directly from the base class). This\n  renders the meaning of the program undefined.  In the future, a\n  check may be added to prevent this.\n\n* Nonempty *__slots__* does not work for classes derived from\n  "variable-length" built-in types such as "int", "bytes" and "tuple".\n\n* Any non-string iterable may be assigned to *__slots__*. Mappings may\n  also be used; however, in the future, special meaning may be\n  assigned to the values corresponding to each key.\n\n* *__class__* assignment works only if both classes have the same\n  *__slots__*.\n',
+ 'attribute-references': '\nAttribute references\n********************\n\nAn attribute reference is a primary followed by a period and a name:\n\n   attributeref ::= primary "." identifier\n\nThe primary must evaluate to an object of a type that supports\nattribute references, which most objects do.  This object is then\nasked to produce the attribute whose name is the identifier (which can\nbe customized by overriding the "__getattr__()" method).  If this\nattribute is not available, the exception "AttributeError" is raised.\nOtherwise, the type and value of the object produced is determined by\nthe object.  Multiple evaluations of the same attribute reference may\nyield different objects.\n',
+ 'augassign': '\nAugmented assignment statements\n*******************************\n\nAugmented assignment is the combination, in a single statement, of a\nbinary operation and an assignment statement:\n\n   augmented_assignment_stmt ::= augtarget augop (expression_list | yield_expression)\n   augtarget                 ::= identifier | attributeref | subscription | slicing\n   augop                     ::= "+=" | "-=" | "*=" | "/=" | "//=" | "%=" | "**="\n             | ">>=" | "<<=" | "&=" | "^=" | "|="\n\n(See section *Primaries* for the syntax definitions for the last three\nsymbols.)\n\nAn augmented assignment evaluates the target (which, unlike normal\nassignment statements, cannot be an unpacking) and the expression\nlist, performs the binary operation specific to the type of assignment\non the two operands, and assigns the result to the original target.\nThe target is only evaluated once.\n\nAn augmented assignment expression like "x += 1" can be rewritten as\n"x = x + 1" to achieve a similar, but not exactly equal effect.

+ 'binary': '\nBinary arithmetic operations\n****************************\n\nThe binary arithmetic operations have the conventional priority\nlevels.  Note that some of these operations also apply to certain non-\nnumeric types.  Apart from the power operator, there are only two\nlevels, one for multiplicative operators and one for additive\noperators:\n\n   m_expr ::= u_expr | m_expr "*" u_expr | m_expr "//" u_expr | m_expr "/" u_expr\n              | m_expr "%" u_expr\n   a_expr ::= m_expr | a_expr "+" m_expr | a_expr "-" m_expr\n\nThe "*" (multiplication) operator yields the product of its arguments.\nThe arguments must either both be numbers, or one argument must be an\ninteger and the other must be a sequence. In the former case, the\nnumbers are converted to a common type and then multiplied together.\nIn the latter case, sequence repetition is performed; a negative\nrepetition factor yields an empty sequence.\n\nThe "/" (division) and "//" (floor division) operators yield the\nquotient of their arguments.  The numeric arguments are first\nconverted to a common type. Division of integers yields a float, while\nfloor division of integers results in an integer; the result is that\nof mathematical division with the \'floor\' function applied to the\nresult.  Division by zero raises the "ZeroDivisionError" exception.\n\nThe "%" (modulo) operator yields the remainder from the division of\nthe first argument by the second.  The numeric arguments are first\nconverted to a common type.  A zero right argument raises the\n"ZeroDivisionError" exception.  The arguments may be floating point\nnumbers, e.g., "3.14%0.7" equals "0.34" (since "3.14" equals "4*0.7 +\n0.34".)  The modulo operator always yields a result with the same sign\nas its second operand (or zero); the absolute value of the result is\nstrictly smaller than the absolute value of the second operand [1].\n\nThe floor division and modulo operators are connected by the following\nidentity: "x == (x//y)*y + (x%y)".  Floor division and modulo are also\nconnected with the built-in function "divmod()": "divmod(x, y) ==\n(x//y, x%y)". [2].\n\nIn addition to performing the modulo operation on numbers, the "%"\noperator is also overloaded by string objects to perform old-style\nstring formatting (also known as interpolation).  The syntax for\nstring formatting is described in the Python Library Reference,\nsection *printf-style String Formatting*.\n\nThe floor division operator, the modulo operator, and the "divmod()"\nfunction are not defined for complex numbers.  Instead, convert to a\nfloating point number using the "abs()" function if appropriate.\n\nThe "+" (addition) operator yields the sum of its arguments.  The\narguments must either both be numbers or both sequences of the same\ntype.  In the former case, the numbers are converted to a common type\nand then added together.  In the latter case, the sequences are\nconcatenated.\n\nThe "-" (subtraction) operator yields the difference of its arguments.\nThe numeric arguments are first converted to a common type.\n',

+ 'bltin-code-objects': '\nCode Objects\n************\n\nCode objects are used by the implementation to represent "pseudo-\ncompiled" executable Python code such as a function body. They differ\nfrom function objects because they don\'t contain a reference to their\nglobal execution environment.  Code objects are returned by the built-\nin "compile()" function and can be extracted from function objects\nthrough their "__code__" attribute. See also the "code" module.\n\nA code object can be executed or evaluated by passing it (instead of a\nsource string) to the "exec()" or "eval()"  built-in functions.\n\nSee *The standard type hierarchy* for more information.\n',

All other values are interpreted\nas true.  User-defined objects can customize their truth value by\nproviding a "__bool__()" method.\n\nThe operator "not" yields "True" if its argument is false, "False"\notherwise.\n\nThe expression "x and y" first evaluates *x*; if *x* is false, its\nvalue is returned; otherwise, *y* is evaluated and the resulting value\nis returned.\n\nThe expression "x or y" first evaluates *x*; if *x* is true, its value\nis returned; otherwise, *y* is evaluated and the resulting value is\nreturned.\n\n(Note that neither "and" nor "or" restrict the value and type they\nreturn to "False" and "True", but rather return the last evaluated\nargument.  This is sometimes useful, e.g., if "s" is a string that\nshould be replaced by a default value if it is empty, the expression\n"s or \'foo\'" yields the desired value.  Because "not" has to invent a\nvalue anyway, it does not bother to return a value of the same type as\nits argument, so e.g., "not \'foo\'" yields "False", not "\'\'".)\n',

All argument expressions are\nevaluated before the call is attempted.  Please refer to section\n*Function definitions* for the syntax of formal *parameter* lists.\n\nIf keyword arguments are present, they are first converted to\npositional arguments, as follows.  First, a list of unfilled slots is\ncreated for the formal parameters.  If there are N positional\narguments, they are placed in the first N slots.  Next, for each\nkeyword argument, the identifier is used to determine the\ncorresponding slot (if the identifier is the same as the first formal\nparameter name, the first slot is used, and so on).  If the slot is\nalready filled, a "TypeError" exception is raised. Otherwise, the\nvalue of the argument is placed in the slot, filling it (even if the\nexpression is "None", it fills the slot).  When all arguments have\nbeen processed, the slots that are still unfilled are filled with the\ncorresponding default value from the function definition.  (Default\nvalues are calculated, once, when the function is defined; thus, a\nmutable object such as a list or dictionary used as default value will\nbe shared by all calls that don\'t specify an argument value for the\ncorresponding slot; this should usually be avoided.)  If there are any\nunfilled slots for which no default value is specified, a "TypeError"\nexception is raised.  Otherwise, the list of filled slots is used as\nthe argument list for the call.\n\n**CPython implementation detail:** An implementation may provide\nbuilt-in functions whose positional parameters do not have names, even\nif they are \'named\' for the purpose of documentation, and which\ntherefore cannot be supplied by keyword.  In CPython, this is the case\nfor functions implemented in C that use "PyArg_ParseTuple()" to parse\ntheir arguments.\n\nIf there are more positional arguments than there are formal parameter\nslots, a "TypeError" exception is raised, unless a formal parameter\nusing the syntax "*identifier" is present; in this case, that formal\nparameter receives a tuple containing the excess positional arguments\n(or an empty tuple if there were no excess positional arguments).\n\nIf any keyword argument does not correspond to a formal parameter\nname, a "TypeError" exception is raised, unless a formal parameter\nusing the syntax "**identifier" is present; in this case, that formal\nparameter receives a dictionary containing the excess keyword\narguments (using the keywords as keys and the argument values as\ncorresponding values), or a (new) empty dictionary if there were no\nexcess keyword arguments.\n\nIf the syntax "*expression" appears in the function call, "expression"\nmust evaluate to an iterable.  Elements from this iterable are treated\nas if they were additional positional arguments; if there are\npositional arguments *x1*, ..., *xN*, and "expression" evaluates to a\nsequence *y1*, ..., *yM*, this is equivalent to a call with M+N\npositional arguments *x1*, ..., *xN*, *y1*, ..., *yM*.\n\nA consequence of this is that although the "*expression" syntax may\nappear *after* some keyword arguments, it is processed *before* the\nkeyword arguments (and the "**expression" argument, if any -- see\nbelow).  So:\n\n   >>> def f(a, b):\n   ...  print(a, b)\n   ...\n   >>> f(b=1, *(2,))\n   2 1\n   >>> f(a=1, *(2,))\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in ?\n   TypeError: f() got multiple values for keyword argument \'a\'\n   >>> f(1, *(2,))\n   1 2\n\nIt is unusual for both keyword arguments and the "*expression" syntax\nto be used in the same call, so in practice this confusion does not\narise.\n\nIf the syntax "**expression" appears in the function call,\n"expression" must evaluate to a mapping, the contents of which are\ntreated as additional keyword arguments.  In the case of a keyword\nappearing in both "expression" and as an explicit keyword argument, a\n"TypeError" exception is raised.\n\nFormal parameters using the syntax "*identifier" or "**identifier"\ncannot be used as positional argument slots or as keyword argument\nnames.\n\nA call always returns some value, possibly "None", unless it raises an\nexception.  How this value is computed depends on the type of the\ncallable object.\n\nIf it is---\n\na user-defined function:\n   The code block for the function is executed, passing it the\n   argument list.  The first thing the code block will do is bind the\n   formal parameters to the arguments; this is described in section\n   *Function definitions*.  When the code block executes a "return"\n   statement, this specifies the return value of the function call.\n\na built-in function or method:\n   The result is up to the interpreter; see *Built-in Functions* for\n   the descriptions of built-in functions and methods.\n\na class object:\n   A new instance of that class is returned.\n\na class instance method:\n   The corresponding user-defined function is called, with an argument\n   list that is one longer than the argument list of the call: the\n   instance becomes the first argument.\n\na class instance:\n   The class must define a "__call__()" method; the effect is then the\n   same as if that method was called.\n',
+ 'class': '\nClass definitions\n*****************\n\nA class definition defines a class object (see section *The standard\ntype hierarchy*):\n\n   classdef    ::= [decorators] "class" classname [inheritance] ":" suite\n   inheritance ::= "(" [parameter_list] ")"\n   classname   ::= identifier\n\nA class definition is an executable statement.  The inheritance list\nusually gives a list of base classes (see *Customizing class creation*\nfor more advanced uses), so each item in the list should evaluate to a\nclass object which allows subclassing.  Classes without an inheritance\nlist inherit, by default, from the base class "object"; hence,\n\n   class Foo:\n       pass\n\nis equivalent to\n\n   class Foo(object):\n       pass\n\nThe class\'s suite is then executed in a new execution frame (see\n*Naming and binding*), using a newly created local namespace and the\noriginal global namespace. (Usually, the suite contains mostly\nfunction definitions.)  When the class\'s suite finishes execution, its\nexecution frame is discarded but its local namespace is saved. [4] A\nclass object is then created using the inheritance list for the base\nclasses and the saved local namespace for the attribute dictionary.\nThe class name is bound to this class object in the original local\nnamespace.\n\nClass creation can be customized heavily using *metaclasses*.\n\nClasses can also be decorated: just like when decorating functions,\n\n   @f1(arg)\n   @f2\n   class Foo: pass\n\nis equivalent to\n\n   class Foo: pass\n   Foo = f1(arg)(f2(Foo))\n\nThe evaluation rules for the decorator expressions are the same as for\nfunction decorators.  The result must be a class object, which is then\nbound to the class name.\n\n**Programmer\'s note:** Variables defined in the class definition are\nclass attributes; they are shared by instances.  Instance attributes\ncan be set in a method with "self.name = value".  Both class and\ninstance attributes are accessible through the notation ""self.name"",\nand an instance attribute hides a class attribute with the same name\nwhen accessed in this way.  Class attributes can be used as defaults\nfor instance attributes, but using mutable values there can lead to\nunexpected results.  *Descriptors* can be used to create instance\nvariables with different implementation details.\n\nSee also:\n\n   **PEP 3115** - Metaclasses in Python 3 **PEP 3129** - Class\n   Decorators\n\n-[ Footnotes ]-\n\n[1] The exception is propagated to the invocation stack unless there\n    is a "finally" clause which happens to raise another exception.\n    That new exception causes the old one to be lost.\n\n[2] Currently, control "flows off the end" except in the case of an\n    exception or the execution of a "return", "continue", or "break"\n    statement.\n\n[3] A string literal appearing as the first statement in the function\n    body is transformed into the function\'s "__doc__" attribute and\n    therefore the function\'s *docstring*.\n\n[4] A string literal appearing as the first statement in the class\n    body is transformed into the namespace\'s "__doc__" item and\n    therefore the class\'s *docstring*.\n',
+ 'comparisons': '\nComparisons\n***********\n\nUnlike C, all comparison operations in Python have the same priority,\nwhich is lower than that of any arithmetic, shifting or bitwise\noperation.  Also unlike C, expressions like "a < b < c" have the\ninterpretation that is conventional in mathematics:\n\n   comparison    ::= or_expr ( comp_operator or_expr )*\n   comp_operator ::= "<" | ">" | "==" | ">=" | "<=" | "!="\n                     | "is" ["not"] | ["not"] "in"\n\nComparisons yield boolean values: "True" or "False".\n\nComparisons can be chained arbitrarily, e.g., "x < y <= z" is\nequivalent to "x < y and y <= z", except that "y" is evaluated only\nonce (but in both cases "z" is not evaluated at all when "x < y" is\nfound to be false).\n\nFormally, if *a*, *b*, *c*, ..., *y*, *z* are expressions and *op1*,\n*op2*, ..., *opN* are comparison operators, then "a op1 b op2 c ... y\nopN z" is equivalent to "a op1 b and b op2 c and ... y opN z", except\nthat each expression is evaluated at most once.\n\nNote that "a op1 b op2 c" doesn\'t imply any kind of comparison between\n*a* and *c*, so that, e.g., "x < y > z" is perfectly legal (though\nperhaps not pretty).\n\nThe operators "<", ">", "==", ">=", "<=", and "!=" compare the values\nof two objects.  The objects need not have the same type. If both are\nnumbers, they are converted to a common type.  Otherwise, the "==" and\n"!=" operators *always* consider objects of different types to be\nunequal, while the "<", ">", ">=" and "<=" operators raise a\n"TypeError" when comparing objects of different types that do not\nimplement these operators for the given pair of types.  You can\ncontrol comparison behavior of objects of non-built-in types by\ndefining rich comparison methods like "__gt__()", described in section\n*Basic customization*.\n\nComparison of objects of the same type depends on the type:\n\n* Numbers are compared arithmetically.\n\n* The values "float(\'NaN\')" and "Decimal(\'NaN\')" are special. The are\n  identical to themselves, "x is x" but are not equal to themselves,\n  "x != x".  Additionally, comparing any value to a not-a-number value\n  will return "False".  For example, both "3 < float(\'NaN\')" and\n  "float(\'NaN\') < 3" will return "False".\n\n* Bytes objects are compared lexicographically using the numeric\n  values of their elements.\n\n* Strings are compared lexicographically using the numeric equivalents\n  (the result of the built-in function "ord()") of their characters.\n  [3] String and bytes object can\'t be compared!\n\n* Tuples and lists are compared lexicographically using comparison of\n  corresponding elements.  This means that to compare equal, each\n  element must compare equal and the two sequences must be of the same\n  type and have the same length.\n\n  If not equal, the sequences are ordered the same as their first\n  differing elements.  For example, "[1,2,x] <= [1,2,y]" has the same\n  value as "x <= y".  If the corresponding element does not exist, the\n  shorter sequence is ordered first (for example, "[1,2] < [1,2,3]").\n\n* Mappings (dictionaries) compare equal if and only if they have the\n  same "(key, value)" pairs. Order comparisons "(\'<\', \'<=\', \'>=\',\n  \'>\')" raise "TypeError".\n\n* Sets and frozensets define comparison operators to mean subset and\n  superset tests.  Those relations do not define total orderings (the\n  two sets "{1,2}" and {2,3} are not equal, nor subsets of one\n  another, nor supersets of one another).  Accordingly, sets are not\n  appropriate arguments for functions which depend on total ordering.\n  For example, "min()", "max()", and "sorted()" produce undefined\n  results given a list of sets as inputs.\n\n* Most other objects of built-in types compare unequal unless they are\n  the same object; the choice whether one object is considered smaller\n  or larger than another one is made arbitrarily but consistently\n  within one execution of a program.\n\nComparison of objects of the differing types depends on whether either\nof the types provide explicit support for the comparison.  Most\nnumeric types can be compared with one another.  When cross-type\ncomparison is not supported, the comparison method returns\n"NotImplemented".\n\nThe operators "in" and "not in" test for membership.  "x in s"\nevaluates to true if *x* is a member of *s*, and false otherwise.  "x\nnot in s" returns the negation of "x in s".  All built-in sequences\nand set types support this as well as dictionary, for which "in" tests\nwhether a the dictionary has a given key. For container types such as\nlist, tuple, set, frozenset, dict, or collections.deque, the\nexpression "x in y" is equivalent to "any(x is e or x == e for e in\ny)".\n\nFor the string and bytes types, "x in y" is true if and only if *x* is\na substring of *y*.  An equivalent test is "y.find(x) != -1".  Empty\nstrings are always considered to be a substring of any other string,\nso """ in "abc"" will return "True".\n\nFor user-defined classes which define the "__contains__()" method, "x\nin y" is true if and only if "y.__contains__(x)" is true.\n\nFor user-defined classes which do not define "__contains__()" but do\ndefine "__iter__()", "x in y" is true if some value "z" with "x == z"\nis produced while iterating over "y".  If an exception is raised\nduring the iteration, it is as if "in" raised that exception.\n\nLastly, the old-style iteration protocol is tried: if a class defines\n"__getitem__()", "x in y" is true if and only if there is a non-\nnegative integer index *i* such that "x == y[i]", and all lower\ninteger indices do not raise "IndexError" exception.  (If any other\nexception is raised, it is as if "in" raised that exception).\n\nThe operator "not in" is defined to have the inverse true value of\n"in".\n\nThe operators "is" and "is not" test for object identity: "x is y" is\ntrue if and only if *x* and *y* are the same object.  "x is not y"\nyields the inverse truth value. [4]\n',
+ 'compound': '\nCompound statements\n*******************\n\nCompound statements contain (groups of) other statements; they affect\nor control the execution of those other statements in some way.  In\ngeneral, compound statements span multiple lines, although in simple\nincarnations a whole compound statement may be contained in one line.\n\nThe "if", "while" and "for" statements implement traditional control\nflow constructs.  "try" specifies exception handlers and/or cleanup\ncode for a group of statements, while the "with" statement allows the\nexecution of initialization and finalization code around a block of\ncode.  Function and class definitions are also syntactically compound\nstatements.\n\nCompound statements consist of one or more \'clauses.\'  A clause\nconsists of a header and a \'suite.\'  The clause headers of a\nparticular compound statement are all at the same indentation level.\nEach clause header begins with a uniquely identifying keyword and ends\nwith a colon.  A suite is a group of statements controlled by a\nclause.  A suite can be one or more semicolon-separated simple\nstatements on the same line as the header, following the header\'s\ncolon, or it can be one or more indented statements on subsequent\nlines.  Only the latter form of suite can contain nested compound\nstatements; the following is illegal, mostly because it wouldn\'t be\nclear to which "if" clause a following "else" clause would belong:\n\n   if test1: if test2: print(x)\n\nAlso note that the semicolon binds tighter than the colon in this\ncontext, so that in the following example, either all or none of the\n"print()" calls are executed:\n\n   if x < y < z: print(x); print(y); print(z)\n\nSummarizing:\n\n   compound_stmt ::= if_stmt\n                     | while_stmt\n                     | for_stmt\n                     | try_stmt\n                     | with_stmt\n                     | funcdef\n                     | classdef\n   suite         ::= stmt_list NEWLINE | NEWLINE INDENT statement+ DEDENT\n   statement     ::= stmt_list NEWLINE | compound_stmt\n   stmt_list     ::= simple_stmt (";" simple_stmt)* [";"]\n\nNote that statements always end in a "NEWLINE" possibly followed by a\n"DEDENT".  Also note that optional continuation clauses always begin\nwith a keyword that cannot start a statement, thus there are no\nambiguities (the \'dangling "else"\' problem is solved in Python by\nrequiring nested "if" statements to be indented).\n\nThe formatting of the grammar rules in the following sections places\neach clause on a separate line for clarity.\n\n\nThe "if" statement\n==================\n\nThe "if" statement is used for conditional execution:\n\n   if_stmt ::= "if" expression ":" suite\n               ( "elif" expression ":" suite )*\n               ["else" ":" suite]\n\nIt selects exactly one of the suites by evaluating the expressions one\nby one until one is found to be true (see section *Boolean operations*\nfor the definition of true and false); then that suite is executed\n(and no other part of the "if" statement is executed or evaluated).\nIf all expressions are false, the suite of the "else" clause, if\npresent, is executed.\n\n\nThe "while" statement\n=====================\n\nThe "while" statement is used for repeated execution as long as an\nexpression is true:\n\n   while_stmt ::= "while" expression ":" suite\n                  ["else" ":" suite]\n\nThis repeatedly tests the expression and, if it is true, executes the\nfirst suite; if the expression is false (which may be the first time\nit is tested) the suite of the "else" clause, if present, is executed\nand the loop terminates.\n\nA "break" statement executed in the first suite terminates the loop\nwithout executing the "else" clause\'s suite.  A "continue" statement\nexecuted in the first suite skips the rest of the suite and goes back\nto testing the expression.\n\n\nThe "for" statement\n===================\n\nThe "for" statement is used to iterate over the elements of a sequence\n(such as a string, tuple or list) or other iterable object:\n\n   for_stmt ::= "for" target_list "in" expression_list ":" suite\n                ["else" ":" suite]\n\nThe expression list is evaluated once; it should yield an iterable\nobject.  An iterator is created for the result of the\n"expression_list".  The suite is then executed once for each item\nprovided by the iterator, in the order of ascending indices.  Each\nitem in turn is assigned to the target list using the standard rules\nfor assignments (see *Assignment statements*), and then the suite is\nexecuted.  When the items are exhausted (which is immediately when the\nsequence is empty or an iterator raises a "StopIteration" exception),\nthe suite in the "else" clause, if present, is executed, and the loop\nterminates.\n\nA "break" statement executed in the first suite terminates the loop\nwithout executing the "else" clause\'s suite.  A "continue" statement\nexecuted in the first suite skips the rest of the suite and continues\nwith the next item, or with the "else" clause if there was no next\nitem.\n\nThe suite may assign to the variable(s) in the target list; this does\nnot affect the next item assigned to it.\n\nNames in the target list are not deleted when the loop is finished,\nbut if the sequence is empty, it will not have been assigned to at all\nby the loop.  Hint: the built-in function "range()" returns an\niterator of integers suitable to emulate the effect of Pascal\'s "for i\n:= a to b do"; e.g., "list(range(3))" returns the list "[0, 1, 2]".\n\nNote: There is a subtlety when the sequence is being modified by the loop\n  (this can only occur for mutable sequences, i.e. lists).  An\n  internal counter is used to keep track of which item is used next,\n  and this is incremented on each iteration.  When this counter has\n  reached the length of the sequence the loop terminates.  This means\n  that if the suite deletes the current (or a previous) item from the\n  sequence, the next item will be skipped (since it gets the index of\n  the current item which has already been treated).  Likewise, if the\n  suite inserts an item in the sequence before the current item, the\n  current item will be treated again the next time through the loop.\n  This can lead to nasty bugs that can be avoided by making a\n  temporary copy using a slice of the whole sequence, e.g.,\n\n     for x in a[:]:\n         if x < 0: a.remove(x)\n\n\nThe "try" statement\n===================\n\nThe "try" statement specifies exception handlers and/or cleanup code\nfor a group of statements:\n\n   try_stmt  ::= try1_stmt | try2_stmt\n   try1_stmt ::= "try" ":" suite\n                 ("except" [expression ["as" target]] ":" suite)+\n                 ["else" ":" suite]\n                 ["finally" ":" suite]\n   try2_stmt ::= "try" ":" suite\n                 "finally" ":" suite\n\nThe "except" clause(s) specify one or more exception handlers. When no\nexception occurs in the "try" clause, no exception handler is\nexecuted. When an exception occurs in the "try" suite, a search for an\nexception handler is started.  This search inspects the except clauses\nin turn until one is found that matches the exception.  An expression-\nless except clause, if present, must be last; it matches any\nexception.  For an except clause with an expression, that expression\nis evaluated, and the clause matches the exception if the resulting\nobject is "compatible" with the exception.  An object is compatible\nwith an exception if it is the class or a base class of the exception\nobject or a tuple containing an item compatible with the exception.\n\nIf no except clause matches the exception, the search for an exception\nhandler continues in the surrounding code and on the invocation stack.\n[1]\n\nIf the evaluation of an expression in the header of an except clause\nraises an exception, the original search for a handler is canceled and\na search starts for the new exception in the surrounding code and on\nthe call stack (it is treated as if the entire "try" statement raised\nthe exception).\n\nWhen a matching except clause is found, the exception is assigned to\nthe target specified after the "as" keyword in that except clause, if\npresent, and the except clause\'s suite is executed.  All except\nclauses must have an executable block.  When the end of this block is\nreached, execution continues normally after the entire try statement.\n(This means that if two nested handlers exist for the same exception,\nand the exception occurs in the try clause of the inner handler, the\nouter handler will not handle the exception.)\n\nWhen an exception has been assigned using "as target", it is cleared\nat the end of the except clause.  This is as if\n\n   except E as N:\n       foo\n\nwas translated to\n\n   except E as N:\n       try:\n           foo\n       finally:\n           del N\n\nThis means the exception must be assigned to a different name to be\nable to refer to it after the except clause.  Exceptions are cleared\nbecause with the traceback attached to them, they form a reference\ncycle with the stack frame, keeping all locals in that frame alive\nuntil the next garbage collection occurs.\n\nBefore an except clause\'s suite is executed, details about the\nexception are stored in the "sys" module and can be access via\n"sys.exc_info()". "sys.exc_info()" returns a 3-tuple consisting of the\nexception class, the exception instance and a traceback object (see\nsection *The standard type hierarchy*) identifying the point in the\nprogram where the exception occurred.  "sys.exc_info()" values are\nrestored to their previous values (before the call) when returning\nfrom a function that handled an exception.\n\nThe optional "else" clause is executed if and when control flows off\nthe end of the "try" clause. [2] Exceptions in the "else" clause are\nnot handled by the preceding "except" clauses.\n\nIf "finally" is present, it specifies a \'cleanup\' handler.  The "try"\nclause is executed, including any "except" and "else" clauses.  If an\nexception occurs in any of the clauses and is not handled, the\nexception is temporarily saved. The "finally" clause is executed.  If\nthere is a saved exception it is re-raised at the end of the "finally"\nclause.  If the "finally" clause raises another exception, the saved\nexception is set as the context of the new exception. If the "finally"\nclause executes a "return" or "break" statement, the saved exception\nis discarded:\n\n   >>> def f():\n   ...     try:\n   ...         1/0\n   ...     finally:\n   ...         return 42\n   ...\n   >>> f()\n   42\n\nThe exception information is not available to the program during\nexecution of the "finally" clause.\n\nWhen a "return", "break" or "continue" statement is executed in the\n"try" suite of a "try"..."finally" statement, the "finally" clause is\nalso executed \'on the way out.\' A "continue" statement is illegal in\nthe "finally" clause. (The reason is a problem with the current\nimplementation --- this restriction may be lifted in the future).\n\nThe return value of a function is determined by the last "return"\nstatement executed.  Since the "finally" clause always executes, a\n"return" statement executed in the "finally" clause will always be the\nlast one executed:\n\n   >>> def foo():\n   ...     try:\n   ...         return \'try\'\n   ...     finally:\n   ...         return \'finally\'\n   ...\n   >>> foo()\n   \'finally\'\n\nAdditional information on exceptions can be found in section\n*Exceptions*, and information on using the "raise" statement to\ngenerate exceptions may be found in section *The raise statement*.\n\n\nThe "with" statement\n====================\n\nThe "with" statement is used to wrap the execution of a block with\nmethods defined by a context manager (see section *With Statement\nContext Managers*). This allows common "try"..."except"..."finally"\nusage patterns to be encapsulated for convenient reuse.\n\n   with_stmt ::= "with" with_item ("," with_item)* ":" suite\n   with_item ::= expression ["as" target]\n\nThe execution of the "with" statement with one "item" proceeds as\nfollows:\n\n1. The context expression (the expression given in the "with_item") is\n   evaluated to obtain a context manager.\n\n2. The context manager\'s "__exit__()" is loaded for later use.\n\n3. The context manager\'s "__enter__()" method is invoked.\n\n4. If a target was included in the "with" statement, the return value\n   from "__enter__()" is assigned to it.\n\n   Note: The "with" statement guarantees that if the "__enter__()" method\n     returns without an error, then "__exit__()" will always be\n     called. Thus, if an error occurs during the assignment to the\n     target list, it will be treated the same as an error occurring\n     within the suite would be. See step 6 below.\n\n5. The suite is executed.\n\n6. The context manager\'s "__exit__()" method is invoked.  If an\n   exception caused the suite to be exited, its type, value, and\n   traceback are passed as arguments to "__exit__()". Otherwise, three\n   "None" arguments are supplied.\n\n   If the suite was exited due to an exception, and the return value\n   from the "__exit__()" method was false, the exception is reraised.\n   If the return value was true, the exception is suppressed, and\n   execution continues with the statement following the "with"\n   statement.\n\n   If the suite was exited for any reason other than an exception, the\n   return value from "__exit__()" is ignored, and execution proceeds\n   at the normal location for the kind of exit that was taken.\n\nWith more than one item, the context managers are processed as if\nmultiple "with" statements were nested:\n\n   with A() as a, B() as b:\n       suite\n\nis equivalent to\n\n   with A() as a:\n       with B() as b:\n           suite\n\nChanged in version 3.1: Support for multiple context expressions.\n\nSee also:\n\n   **PEP 0343** - The "with" statement\n      The specification, background, and examples for the Python\n      "with" statement.\n\n\nFunction definitions\n====================\n\nA function definition defines a user-defined function object (see\nsection *The standard type hierarchy*):\n\n   funcdef        ::= [decorators] "def" funcname "(" [parameter_list] ")" ["->" expression] ":" suite\n   decorators     ::= decorator+\n   decorator      ::= "@" dotted_name ["(" [parameter_list [","]] ")"] NEWLINE\n   dotted_name    ::= identifier ("." identifier)*\n   parameter_list ::= (defparameter ",")*\n                      ( "*" [parameter] ("," defparameter)* ["," "**" parameter]\n                      | "**" parameter\n                      | defparameter [","] )\n   parameter      ::= identifier [":" expression]\n   defparameter   ::= parameter ["=" expression]\n   funcname       ::= identifier\n\nA function definition is an executable statement.  Its execution binds\nthe function name in the current local namespace to a function object\n(a wrapper around the executable code for the function).  This\nfunction object contains a reference to the current global namespace\nas the global namespace to be used when the function is called.\n\nThe function definition does not execute the function body; this gets\nexecuted only when the function is called. [3]\n\nA function definition may be wrapped by one or more *decorator*\nexpressions. Decorator expressions are evaluated when the function is\ndefined, in the scope that contains the function definition.  The\nresult must be a callable, which is invoked with the function object\nas the only argument. The returned value is bound to the function name\ninstead of the function object.  Multiple decorators are applied in\nnested fashion. For example, the following code\n\n   @f1(arg)\n   @f2\n   def func(): pass\n\nis equivalent to\n\n   def func(): pass\n   func = f1(arg)(f2(func))\n\nWhen one or more *parameters* have the form *parameter* "="\n*expression*, the function is said to have "default parameter values."\nFor a parameter with a default value, the corresponding *argument* may\nbe omitted from a call, in which case the parameter\'s default value is\nsubstituted.  If a parameter has a default value, all following\nparameters up until the ""*"" must also have a default value --- this\nis a syntactic restriction that is not expressed by the grammar.\n\n**Default parameter values are evaluated from left to right when the\nfunction definition is executed.** This means that the expression is\nevaluated once, when the function is defined, and that the same "pre-\ncomputed" value is used for each call.  This is especially important\nto understand when a default parameter is a mutable object, such as a\nlist or a dictionary: if the function modifies the object (e.g. by\nappending an item to a list), the default value is in effect modified.\nThis is generally not what was intended.  A way around this is to use\n"None" as the default, and explicitly test for it in the body of the\nfunction, e.g.:\n\n   def whats_on_the_telly(penguin=None):\n       if penguin is None:\n           penguin = []\n       penguin.append("property of the zoo")\n       return penguin\n\nFunction call semantics are described in more detail in section\n*Calls*. A function call always assigns values to all parameters\nmentioned in the parameter list, either from position arguments, from\nkeyword arguments, or from default values.  If the form\n""*identifier"" is present, it is initialized to a tuple receiving any\nexcess positional parameters, defaulting to the empty tuple.  If the\nform ""**identifier"" is present, it is initialized to a new\ndictionary receiving any excess keyword arguments, defaulting to a new\nempty dictionary. Parameters after ""*"" or ""*identifier"" are\nkeyword-only parameters and may only be passed used keyword arguments.\n\nParameters may have annotations of the form "": expression"" following\nthe parameter name.  Any parameter may have an annotation even those\nof the form "*identifier" or "**identifier".  Functions may have\n"return" annotation of the form ""-> expression"" after the parameter\nlist.  These annotations can be any valid Python expression and are\nevaluated when the function definition is executed.  Annotations may\nbe evaluated in a different order than they appear in the source code.\nThe presence of annotations does not change the semantics of a\nfunction.  The annotation values are available as values of a\ndictionary keyed by the parameters\' names in the "__annotations__"\nattribute of the function object.\n\nIt is also possible to create anonymous functions (functions not bound\nto a name), for immediate use in expressions.  This uses lambda\nexpressions, described in section *Lambdas*.  Note that the lambda\nexpression is merely a shorthand for a simplified function definition;\na function defined in a ""def"" statement can be passed around or\nassigned to another name just like a function defined by a lambda\nexpression.  The ""def"" form is actually more powerful since it\nallows the execution of multiple statements and annotations.\n\n**Programmer\'s note:** Functions are first-class objects.  A ""def""\nstatement executed inside a function definition defines a local\nfunction that can be returned or passed around.  Free variables used\nin the nested function can access the local variables of the function\ncontaining the def.  See section *Naming and binding* for details.\n\nSee also:\n\n   **PEP 3107** - Function Annotations\n      The original specification for function annotations.\n\n\nClass definitions\n=================\n\nA class definition defines a class object (see section *The standard\ntype hierarchy*):\n\n   classdef    ::= [decorators] "class" classname [inheritance] ":" suite\n   inheritance ::= "(" [parameter_list] ")"\n   classname   ::= identifier\n\nA class definition is an executable statement.  The inheritance list\nusually gives a list of base classes (see *Customizing class creation*\nfor more advanced uses), so each item in the list should evaluate to a\nclass object which allows subclassing.  Classes without an inheritance\nlist inherit, by default, from the base class "object"; hence,\n\n   class Foo:\n       pass\n\nis equivalent to\n\n   class Foo(object):\n       pass\n\nThe class\'s suite is then executed in a new execution frame (see\n*Naming and binding*), using a newly created local namespace and the\noriginal global namespace. (Usually, the suite contains mostly\nfunction definitions.)  When the class\'s suite finishes execution, its\nexecution frame is discarded but its local namespace is saved. [4] A\nclass object is then created using the inheritance list for the base\nclasses and the saved local namespace for the attribute dictionary.\nThe class name is bound to this class object in the original local\nnamespace.\n\nClass creation can be customized heavily using *metaclasses*.\n\nClasses can also be decorated: just like when decorating functions,\n\n   @f1(arg)\n   @f2\n   class Foo: pass\n\nis equivalent to\n\n   class Foo: pass\n   Foo = f1(arg)(f2(Foo))\n\nThe evaluation rules for the decorator expressions are the same as for\nfunction decorators.  The result must be a class object, which is then\nbound to the class name.\n\n**Programmer\'s note:** Variables defined in the class definition are\nclass attributes; they are shared by instances.  Instance attributes\ncan be set in a method with "self.name = value".  Both class and\ninstance attributes are accessible through the notation ""self.name"",\nand an instance attribute hides a class attribute with the same name\nwhen accessed in this way.  Class attributes can be used as defaults\nfor instance attributes, but using mutable values there can lead to\nunexpected results.  *Descriptors* can be used to create instance\nvariables with different implementation details.\n\nSee also:\n\n   **PEP 3115** - Metaclasses in Python 3 **PEP 3129** - Class\n   Decorators\n\n-[ Footnotes ]-\n\n[1] The exception is propagated to the invocation stack unless there\n    is a "finally" clause which happens to raise another exception.\n    That new exception causes the old one to be lost.\n\n[2] Currently, control "flows off the end" except in the case of an\n    exception or the execution of a "return", "continue", or "break"\n    statement.\n\n[3] A string literal appearing as the first statement in the function\n    body is transformed into the function\'s "__doc__" attribute and\n    therefore the function\'s *docstring*.\n\n[4] A string literal appearing as the first statement in the class\n    body is transformed into the namespace\'s "__doc__" item and\n    therefore the class\'s *docstring*.\n',
+ 'context-managers': '\nWith Statement Context Managers\n*******************************\n\nA *context manager* is an object that defines the runtime context to\nbe established when executing a "with" statement. The context manager\nhandles the entry into, and the exit from, the desired runtime context\nfor the execution of the block of code.  Context managers are normally\ninvoked using the "with" statement (described in section *The with\nstatement*), but can also be used by directly invoking their methods.\n\nTypical uses of context managers include saving and restoring various\nkinds of global state, locking and unlocking resources, closing opened\nfiles, etc.\n\nFor more information on context managers, see *Context Manager Types*.\n\nobject.__enter__(self)\n\n   Enter the runtime context related to this object. The "with"\n   statement will bind this method\'s return value to the target(s)\n   specified in the "as" clause of the statement, if any.\n\nobject.__exit__(self, exc_type, exc_value, traceback)\n\n   Exit the runtime context related to this object. The parameters\n   describe the exception that caused the context to be exited. If the\n   context was exited without an exception, all three arguments will\n   be "None".\n\n   If an exception is supplied, and the method wishes to suppress the\n   exception (i.e., prevent it from being propagated), it should\n   return a true value. Otherwise, the exception will be processed\n   normally upon exit from this method.\n\n   Note that "__exit__()" methods should not reraise the passed-in\n   exception; this is the caller\'s responsibility.\n\nSee also:\n\n   **PEP 0343** - The "with" statement\n      The specification, background, and examples for the Python\n      "with" statement.\n',
+ 'continue': '\nThe "continue" statement\n************************\n\n   continue_stmt ::= "continue"\n\n"continue" may only occur syntactically nested in a "for" or "while"\nloop, but not nested in a function or class definition or "finally"\nclause within that loop.  It continues with the next cycle of the\nnearest enclosing loop.\n\nWhen "continue" passes control out of a "try" statement with a\n"finally" clause, that "finally" clause is executed before really\nstarting the next loop cycle.\n',
+ 'conversions': '\nArithmetic conversions\n**********************\n\nWhen a description of an arithmetic operator below uses the phrase\n"the numeric arguments are converted to a common type," this means\nthat the operator implementation for built-in types works that way:\n\n* If either argument is a complex number, the other is converted to\n  complex;\n\n* otherwise, if either argument is a floating point number, the other\n  is converted to floating point;\n\n* otherwise, both must be integers and no conversion is necessary.\n\nSome additional rules apply for certain operators (e.g., a string left\nargument to the \'%\' operator).  Extensions must define their own\nconversion behavior.\n',
+ 'customization': '\nBasic customization\n*******************\n\nobject.__new__(cls[, ...])\n\n   Called to create a new instance of class *cls*.  "__new__()" is a\n   static method (special-cased so you need not declare it as such)\n   that takes the class of which an instance was requested as its\n   first argument.  The remaining arguments are those passed to the\n   object constructor expression (the call to the class).  The return\n   value of "__new__()" should be the new object instance (usually an\n   instance of *cls*).\n\n   Typical implementations create a new instance of the class by\n   invoking the superclass\'s "__new__()" method using\n   "super(currentclass, cls).__new__(cls[, ...])" with appropriate\n   arguments and then modifying the newly-created instance as\n   necessary before returning it.\n\n   If "__new__()" returns an instance of *cls*, then the new\n   instance\'s "__init__()" method will be invoked like\n   "__init__(self[, ...])", where *self* is the new instance and the\n   remaining arguments are the same as were passed to "__new__()".\n\n   If "__new__()" does not return an instance of *cls*, then the new\n   instance\'s "__init__()" method will not be invoked.\n\n   "__new__()" is intended mainly to allow subclasses of immutable\n   types (like int, str, or tuple) to customize instance creation.  It\n   is also commonly overridden in custom metaclasses in order to\n   customize class creation.\n\nobject.__init__(self[, ...])\n\n   Called when the instance is created.  The arguments are those\n   passed to the class constructor expression.  If a base class has an\n   "__init__()" method, the derived class\'s "__init__()" method, if\n   any, must explicitly call it to ensure proper initialization of the\n   base class part of the instance; for example:\n   "BaseClass.__init__(self, [args...])".  As a special constraint on\n   constructors, no value may be returned; doing so will cause a\n   "TypeError" to be raised at runtime.\n\nobject.__del__(self)\n\n   Called when the instance is about to be destroyed.  This is also\n   called a destructor.  If a base class has a "__del__()" method, the\n   derived class\'s "__del__()" method, if any, must explicitly call it\n   to ensure proper deletion of the base class part of the instance.\n   Note that it is possible (though not recommended!) for the\n   "__del__()" method to postpone destruction of the instance by\n   creating a new reference to it.  It may then be called at a later\n   time when this new reference is deleted.  It is not guaranteed that\n   "__del__()" methods are called for objects that still exist when\n   the interpreter exits.\n\n   Note: "del x" doesn\'t directly call "x.__del__()" --- the former\n     decrements the reference count for "x" by one, and the latter is\n     only called when "x"\'s reference count reaches zero.  Some common\n     situations that may prevent the reference count of an object from\n     going to zero include: circular references between objects (e.g.,\n     a doubly-linked list or a tree data structure with parent and\n     child pointers); a reference to the object on the stack frame of\n     a function that caught an exception (the traceback stored in\n     "sys.exc_info()[2]" keeps the stack frame alive); or a reference\n     to the object on the stack frame that raised an unhandled\n     exception in interactive mode (the traceback stored in\n     "sys.last_traceback" keeps the stack frame alive).  The first\n     situation can only be remedied by explicitly breaking the cycles;\n     the latter two situations can be resolved by storing "None" in\n     "sys.last_traceback". Circular references which are garbage are\n     detected and cleaned up when the cyclic garbage collector is\n     enabled (it\'s on by default). Refer to the documentation for the\n     "gc" module for more information about this topic.\n\n   Warning: Due to the precarious circumstances under which "__del__()"\n     methods are invoked, exceptions that occur during their execution\n     are ignored, and a warning is printed to "sys.stderr" instead.\n     Also, when "__del__()" is invoked in response to a module being\n     deleted (e.g., when execution of the program is done), other\n     globals referenced by the "__del__()" method may already have\n     been deleted or in the process of being torn down (e.g. the\n     import machinery shutting down).  For this reason, "__del__()"\n     methods should do the absolute minimum needed to maintain\n     external invariants.  Starting with version 1.5, Python\n     guarantees that globals whose name begins with a single\n     underscore are deleted from their module before other globals are\n     deleted; if no other references to such globals exist, this may\n     help in assuring that imported modules are still available at the\n     time when the "__del__()" method is called.\n\nobject.__repr__(self)\n\n   Called by the "repr()" built-in function to compute the "official"\n   string representation of an object.  If at all possible, this\n   should look like a valid Python expression that could be used to\n   recreate an object with the same value (given an appropriate\n   environment).  If this is not possible, a string of the form\n   "<...some useful description...>" should be returned. The return\n   value must be a string object. If a class defines "__repr__()" but\n   not "__str__()", then "__repr__()" is also used when an "informal"\n   string representation of instances of that class is required.\n\n   This is typically used for debugging, so it is important that the\n   representation is information-rich and unambiguous.\n\nobject.__str__(self)\n\n   Called by "str(object)" and the built-in functions "format()" and\n   "print()" to compute the "informal" or nicely printable string\n   representation of an object.  The return value must be a *string*\n   object.\n\n   This method differs from "object.__repr__()" in that there is no\n   expectation that "__str__()" return a valid Python expression: a\n   more convenient or concise representation can be used.\n\n   The default implementation defined by the built-in type "object"\n   calls "object.__repr__()".\n\nobject.__bytes__(self)\n\n   Called by "bytes()" to compute a byte-string representation of an\n   object. This should return a "bytes" object.\n\nobject.__format__(self, format_spec)\n\n   Called by the "format()" built-in function (and by extension, the\n   "str.format()" method of class "str") to produce a "formatted"\n   string representation of an object. The "format_spec" argument is a\n   string that contains a description of the formatting options\n   desired. The interpretation of the "format_spec" argument is up to\n   the type implementing "__format__()", however most classes will\n   either delegate formatting to one of the built-in types, or use a\n   similar formatting option syntax.\n\n   See *Format Specification Mini-Language* for a description of the\n   standard formatting syntax.\n\n   The return value must be a string object.\n\n   Changed in version 3.4: The __format__ method of "object" itself\n   raises a "TypeError" if passed any non-empty string.\n\nobject.__lt__(self, other)\nobject.__le__(self, other)\nobject.__eq__(self, other)\nobject.__ne__(self, other)\nobject.__gt__(self, other)\nobject.__ge__(self, other)\n\n   These are the so-called "rich comparison" methods. The\n   correspondence between operator symbols and method names is as\n   follows: "x<y" calls "x.__lt__(y)", "x<=y" calls "x.__le__(y)",\n   "x==y" calls "x.__eq__(y)", "x!=y" calls "x.__ne__(y)", "x>y" calls\n   "x.__gt__(y)", and "x>=y" calls "x.__ge__(y)".\n\n   A rich comparison method may return the singleton "NotImplemented"\n   if it does not implement the operation for a given pair of\n   arguments. By convention, "False" and "True" are returned for a\n   successful comparison. However, these methods can return any value,\n   so if the comparison operator is used in a Boolean context (e.g.,\n   in the condition of an "if" statement), Python will call "bool()"\n   on the value to determine if the result is true or false.\n\n   There are no implied relationships among the comparison operators.\n   The truth of "x==y" does not imply that "x!=y" is false.\n   Accordingly, when defining "__eq__()", one should also define\n   "__ne__()" so that the operators will behave as expected.  See the\n   paragraph on "__hash__()" for some important notes on creating\n   *hashable* objects which support custom comparison operations and\n   are usable as dictionary keys.\n\n   There are no swapped-argument versions of these methods (to be used\n   when the left argument does not support the operation but the right\n   argument does); rather, "__lt__()" and "__gt__()" are each other\'s\n   reflection, "__le__()" and "__ge__()" are each other\'s reflection,\n   and "__eq__()" and "__ne__()" are their own reflection.\n\n   Arguments to rich comparison methods are never coerced.\n\n   To automatically generate ordering operations from a single root\n   operation, see "functools.total_ordering()".\n\nobject.__hash__(self)\n\n   Called by built-in function "hash()" and for operations on members\n   of hashed collections including "set", "frozenset", and "dict".\n   "__hash__()" should return an integer.  The only required property\n   is that objects which compare equal have the same hash value; it is\n   advised to somehow mix together (e.g. using exclusive or) the hash\n   values for the components of the object that also play a part in\n   comparison of objects.\n\n   Note: "hash()" truncates the value returned from an object\'s custom\n     "__hash__()" method to the size of a "Py_ssize_t".  This is\n     typically 8 bytes on 64-bit builds and 4 bytes on 32-bit builds.\n     If an object\'s   "__hash__()" must interoperate on builds of\n     different bit sizes, be sure to check the width on all supported\n     builds.  An easy way to do this is with "python -c "import sys;\n     print(sys.hash_info.width)""\n\n   If a class does not define an "__eq__()" method it should not\n   define a "__hash__()" operation either; if it defines "__eq__()"\n   but not "__hash__()", its instances will not be usable as items in\n   hashable collections.  If a class defines mutable objects and\n   implements an "__eq__()" method, it should not implement\n   "__hash__()", since the implementation of hashable collections\n   requires that a key\'s hash value is immutable (if the object\'s hash\n   value changes, it will be in the wrong hash bucket).\n\n   User-defined classes have "__eq__()" and "__hash__()" methods by\n   default; with them, all objects compare unequal (except with\n   themselves) and "x.__hash__()" returns an appropriate value such\n   that "x == y" implies both that "x is y" and "hash(x) == hash(y)".\n\n   A class that overrides "__eq__()" and does not define "__hash__()"\n   will have its "__hash__()" implicitly set to "None".  When the\n   "__hash__()" method of a class is "None", instances of the class\n   will raise an appropriate "TypeError" when a program attempts to\n   retrieve their hash value, and will also be correctly identified as\n   unhashable when checking "isinstance(obj, collections.Hashable").\n\n   If a class that overrides "__eq__()" needs to retain the\n   implementation of "__hash__()" from a parent class, the interpreter\n   must be told this explicitly by setting "__hash__ =\n   <ParentClass>.__hash__".\n\n   If a class that does not override "__eq__()" wishes to suppress\n   hash support, it should include "__hash__ = None" in the class\n   definition. A class which defines its own "__hash__()" that\n   explicitly raises a "TypeError" would be incorrectly identified as\n   hashable by an "isinstance(obj, collections.Hashable)" call.\n\n   Note: By default, the "__hash__()" values of str, bytes and datetime\n     objects are "salted" with an unpredictable random value.\n     Although they remain constant within an individual Python\n     process, they are not predictable between repeated invocations of\n     Python.This is intended to provide protection against a denial-\n     of-service caused by carefully-chosen inputs that exploit the\n     worst case performance of a dict insertion, O(n^2) complexity.\n     See http://www.ocert.org/advisories/ocert-2011-003.html for\n     details.Changing hash values affects the iteration order of\n     dicts, sets and other mappings.  Python has never made guarantees\n     about this ordering (and it typically varies between 32-bit and\n     64-bit builds).See also "PYTHONHASHSEED".\n\n   Changed in version 3.3: Hash randomization is enabled by default.\n\nobject.__bool__(self)\n\n   Called to implement truth value testing and the built-in operation\n   "bool()"; should return "False" or "True".  When this method is not\n   defined, "__len__()" is called, if it is defined, and the object is\n   considered true if its result is nonzero.  If a class defines\n   neither "__len__()" nor "__bool__()", all its instances are\n   considered true.\n',
+ 'debugger': '\n"pdb" --- The Python Debugger\n*****************************\n\nThe module "pdb" defines an interactive source code debugger for\nPython programs.  It supports setting (conditional) breakpoints and\nsingle stepping at the source line level, inspection of stack frames,\nsource code listing, and evaluation of arbitrary Python code in the\ncontext of any stack frame.  It also supports post-mortem debugging\nand can be called under program control.\n\nThe debugger is extensible -- it is actually defined as the class\n"Pdb". This is currently undocumented but easily understood by reading\nthe source.  The extension interface uses the modules "bdb" and "cmd".\n\nThe debugger\'s prompt is "(Pdb)". Typical usage to run a program under\ncontrol of the debugger is:\n\n   >>> import pdb\n   >>> import mymodule\n   >>> pdb.run(\'mymodule.test()\')\n   > <string>(0)?()\n   (Pdb) continue\n   > <string>(1)?()\n   (Pdb) continue\n   NameError: \'spam\'\n   > <string>(1)?()\n   (Pdb)\n\nChanged in version 3.3: Tab-completion via the "readline" module is\navailable for commands and command arguments, e.g. the current global\nand local names are offered as arguments of the "p" command.\n\n"pdb.py" can also be invoked as a script to debug other scripts.  For\nexample:\n\n   python3 -m pdb myscript.py\n\nWhen invoked as a script, pdb will automatically enter post-mortem\ndebugging if the program being debugged exits abnormally.  After post-\nmortem debugging (or after normal exit of the program), pdb will\nrestart the program.  Automatic restarting preserves pdb\'s state (such\nas breakpoints) and in most cases is more useful than quitting the\ndebugger upon program\'s exit.\n\nNew in version 3.2: "pdb.py" now accepts a "-c" option that executes\ncommands as if given in a ".pdbrc" file, see *Debugger Commands*.\n\nThe typical usage to break into the debugger from a running program is\nto insert\n\n   import pdb; pdb.set_trace()\n\nat the location you want to break into the debugger.  You can then\nstep through the code following this statement, and continue running\nwithout the debugger using the "continue" command.\n\nThe typical usage to inspect a crashed program is:\n\n   >>> import pdb\n   >>> import mymodule\n   >>> mymodule.test()\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in ?\n     File "./mymodule.py", line 4, in test\n       test2()\n     File "./mymodule.py", line 3, in test2\n       print(spam)\n   NameError: spam\n   >>> pdb.pm()\n   > ./mymodule.py(3)test2()\n   -> print(spam)\n   (Pdb)\n\nThe module defines the following functions; each enters the debugger\nin a slightly different way:\n\npdb.run(statement, globals=None, locals=None)\n\n   Execute the *statement* (given as a string or a code object) under\n   debugger control.  The debugger prompt appears before any code is\n   executed; you can set breakpoints and type "continue", or you can\n   step through the statement using "step" or "next" (all these\n   commands are explained below).  The optional *globals* and *locals*\n   arguments specify the environment in which the code is executed; by\n   default the dictionary of the module "__main__" is used.  (See the\n   explanation of the built-in "exec()" or "eval()" functions.)\n\npdb.runeval(expression, globals=None, locals=None)\n\n   Evaluate the *expression* (given as a string or a code object)\n   under debugger control.  When "runeval()" returns, it returns the\n   value of the expression.  Otherwise this function is similar to\n   "run()".\n\npdb.runcall(function, *args, **kwds)\n\n   Call the *function* (a function or method object, not a string)\n   with the given arguments.  When "runcall()" returns, it returns\n   whatever the function call returned.  The debugger prompt appears\n   as soon as the function is entered.\n\npdb.set_trace()\n\n   Enter the debugger at the calling stack frame.  This is useful to\n   hard-code a breakpoint at a given point in a program, even if the\n   code is not otherwise being debugged (e.g. when an assertion\n   fails).\n\npdb.post_mortem(traceback=None)\n\n   Enter post-mortem debugging of the given *traceback* object.  If no\n   *traceback* is given, it uses the one of the exception that is\n   currently being handled (an exception must be being handled if the\n   default is to be used).\n\npdb.pm()\n\n   Enter post-mortem debugging of the traceback found in\n   "sys.last_traceback".\n\nThe "run*" functions and "set_trace()" are aliases for instantiating\nthe "Pdb" class and calling the method of the same name.  If you want\nto access further features, you have to do this yourself:\n\nclass class pdb.Pdb(completekey=\'tab\', stdin=None, stdout=None, skip=None, nosigint=False)\n\n   "Pdb" is the debugger class.\n\n   The *completekey*, *stdin* and *stdout* arguments are passed to the\n   underlying "cmd.Cmd" class; see the description there.\n\n   The *skip* argument, if given, must be an iterable of glob-style\n   module name patterns.  The debugger will not step into frames that\n   originate in a module that matches one of these patterns. [1]\n\n   By default, Pdb sets a handler for the SIGINT signal (which is sent\n   when the user presses Ctrl-C on the console) when you give a\n   "continue" command. This allows you to break into the debugger\n   again by pressing Ctrl-C.  If you want Pdb not to touch the SIGINT\n   handler, set *nosigint* tot true.\n\n   Example call to enable tracing with *skip*:\n\n      import pdb; pdb.Pdb(skip=[\'django.*\']).set_trace()\n\n   New in version 3.1: The *skip* argument.\n\n   New in version 3.2: The *nosigint* argument.  Previously, a SIGINT\n   handler was never set by Pdb.\n\n   run(statement, globals=None, locals=None)\n   runeval(expression, globals=None, locals=None)\n   runcall(function, *args, **kwds)\n   set_trace()\n\n      See the documentation for the functions explained above.\n\n\nDebugger Commands\n=================\n\nThe commands recognized by the debugger are listed below.  Most\ncommands can be abbreviated to one or two letters as indicated; e.g.\n"h(elp)" means that either "h" or "help" can be used to enter the help\ncommand (but not "he" or "hel", nor "H" or "Help" or "HELP").\nArguments to commands must be separated by whitespace (spaces or\ntabs).  Optional arguments are enclosed in square brackets ("[]") in\nthe command syntax; the square brackets must not be typed.\nAlternatives in the command syntax are separated by a vertical bar\n("|").\n\nEntering a blank line repeats the last command entered.  Exception: if\nthe last command was a "list" command, the next 11 lines are listed.\n\nCommands that the debugger doesn\'t recognize are assumed to be Python\nstatements and are executed in the context of the program being\ndebugged.  Python statements can also be prefixed with an exclamation\npoint ("!").  This is a powerful way to inspect the program being\ndebugged; it is even possible to change a variable or call a function.\nWhen an exception occurs in such a statement, the exception name is\nprinted but the debugger\'s state is not changed.\n\nThe debugger supports *aliases*.  Aliases can have parameters which\nallows one a certain level of adaptability to the context under\nexamination.\n\nMultiple commands may be entered on a single line, separated by ";;".\n(A single ";" is not used as it is the separator for multiple commands\nin a line that is passed to the Python parser.)  No intelligence is\napplied to separating the commands; the input is split at the first\n";;" pair, even if it is in the middle of a quoted string.\n\nIf a file ".pdbrc" exists in the user\'s home directory or in the\ncurrent directory, it is read in and executed as if it had been typed\nat the debugger prompt.  This is particularly useful for aliases.  If\nboth files exist, the one in the home directory is read first and\naliases defined there can be overridden by the local file.\n\nChanged in version 3.2: ".pdbrc" can now contain commands that\ncontinue debugging, such as "continue" or "next".  Previously, these\ncommands had no effect.\n\nh(elp) [command]\n\n   Without argument, print the list of available commands.  With a\n   *command* as argument, print help about that command.  "help pdb"\n   displays the full documentation (the docstring of the "pdb"\n   module).  Since the *command* argument must be an identifier, "help\n   exec" must be entered to get help on the "!" command.\n\nw(here)\n\n   Print a stack trace, with the most recent frame at the bottom.  An\n   arrow indicates the current frame, which determines the context of\n   most commands.\n\nd(own) [count]\n\n   Move the current frame *count* (default one) levels down in the\n   stack trace (to a newer frame).\n\nu(p) [count]\n\n   Move the current frame *count* (default one) levels up in the stack\n   trace (to an older frame).\n\nb(reak) [([filename:]lineno | function) [, condition]]\n\n   With a *lineno* argument, set a break there in the current file.\n   With a *function* argument, set a break at the first executable\n   statement within that function.  The line number may be prefixed\n   with a filename and a colon, to specify a breakpoint in another\n   file (probably one that hasn\'t been loaded yet).  The file is\n   searched on "sys.path".  Note that each breakpoint is assigned a\n   number to which all the other breakpoint commands refer.\n\n   If a second argument is present, it is an expression which must\n   evaluate to true before the breakpoint is honored.\n\n   Without argument, list all breaks, including for each breakpoint,\n   the number of times that breakpoint has been hit, the current\n   ignore count, and the associated condition if any.\n\ntbreak [([filename:]lineno | function) [, condition]]\n\n   Temporary breakpoint, which is removed automatically when it is\n   first hit. The arguments are the same as for "break".\n\ncl(ear) [filename:lineno | bpnumber [bpnumber ...]]\n\n   With a *filename:lineno* argument, clear all the breakpoints at\n   this line. With a space separated list of breakpoint numbers, clear\n   those breakpoints. Without argument, clear all breaks (but first\n   ask confirmation).\n\ndisable [bpnumber [bpnumber ...]]\n\n   Disable the breakpoints given as a space separated list of\n   breakpoint numbers.  Disabling a breakpoint means it cannot cause\n   the program to stop execution, but unlike clearing a breakpoint, it\n   remains in the list of breakpoints and can be (re-)enabled.\n\nenable [bpnumber [bpnumber ...]]\n\n   Enable the breakpoints specified.\n\nignore bpnumber [count]\n\n   Set the ignore count for the given breakpoint number.  If count is\n   omitted, the ignore count is set to 0.  A breakpoint becomes active\n   when the ignore count is zero.  When non-zero, the count is\n   decremented each time the breakpoint is reached and the breakpoint\n   is not disabled and any associated condition evaluates to true.\n\ncondition bpnumber [condition]\n\n   Set a new *condition* for the breakpoint, an expression which must\n   evaluate to true before the breakpoint is honored.  If *condition*\n   is absent, any existing condition is removed; i.e., the breakpoint\n   is made unconditional.\n\ncommands [bpnumber]\n\n   Specify a list of commands for breakpoint number *bpnumber*.  The\n   commands themselves appear on the following lines.  Type a line\n   containing just "end" to terminate the commands. An example:\n\n      (Pdb) commands 1\n      (com) p some_variable\n      (com) end\n      (Pdb)\n\n   To remove all commands from a breakpoint, type commands and follow\n   it immediately with "end"; that is, give no commands.\n\n   With no *bpnumber* argument, commands refers to the last breakpoint\n   set.\n\n   You can use breakpoint commands to start your program up again.\n   Simply use the continue command, or step, or any other command that\n   resumes execution.\n\n   Specifying any command resuming execution (currently continue,\n   step, next, return, jump, quit and their abbreviations) terminates\n   the command list (as if that command was immediately followed by\n   end). This is because any time you resume execution (even with a\n   simple next or step), you may encounter another breakpoint--which\n   could have its own command list, leading to ambiguities about which\n   list to execute.\n\n   If you use the \'silent\' command in the command list, the usual\n   message about stopping at a breakpoint is not printed.  This may be\n   desirable for breakpoints that are to print a specific message and\n   then continue.  If none of the other commands print anything, you\n   see no sign that the breakpoint was reached.\n\ns(tep)\n\n   Execute the current line, stop at the first possible occasion\n   (either in a function that is called or on the next line in the\n   current function).\n\nn(ext)\n\n   Continue execution until the next line in the current function is\n   reached or it returns.  (The difference between "next" and "step"\n   is that "step" stops inside a called function, while "next"\n   executes called functions at (nearly) full speed, only stopping at\n   the next line in the current function.)\n\nunt(il) [lineno]\n\n   Without argument, continue execution until the line with a number\n   greater than the current one is reached.\n\n   With a line number, continue execution until a line with a number\n   greater or equal to that is reached.  In both cases, also stop when\n   the current frame returns.\n\n   Changed in version 3.2: Allow giving an explicit line number.\n\nr(eturn)\n\n   Continue execution until the current function returns.\n\nc(ont(inue))\n\n   Continue execution, only stop when a breakpoint is encountered.\n\nj(ump) lineno\n\n   Set the next line that will be executed.  Only available in the\n   bottom-most frame.  This lets you jump back and execute code again,\n   or jump forward to skip code that you don\'t want to run.\n\n   It should be noted that not all jumps are allowed -- for instance\n   it is not possible to jump into the middle of a "for" loop or out\n   of a "finally" clause.\n\nl(ist) [first[, last]]\n\n   List source code for the current file.  Without arguments, list 11\n   lines around the current line or continue the previous listing.\n   With "." as argument, list 11 lines around the current line.  With\n   one argument, list 11 lines around at that line.  With two\n   arguments, list the given range; if the second argument is less\n   than the first, it is interpreted as a count.\n\n   The current line in the current frame is indicated by "->".  If an\n   exception is being debugged, the line where the exception was\n   originally raised or propagated is indicated by ">>", if it differs\n   from the current line.\n\n   New in version 3.2: The ">>" marker.\n\nll | longlist\n\n   List all source code for the current function or frame.\n   Interesting lines are marked as for "list".\n\n   New in version 3.2.\n\na(rgs)\n\n   Print the argument list of the current function.\n\np expression\n\n   Evaluate the *expression* in the current context and print its\n   value.\n\n   Note: "print()" can also be used, but is not a debugger command ---\n     this executes the Python "print()" function.\n\npp expression\n\n   Like the "p" command, except the value of the expression is pretty-\n   printed using the "pprint" module.\n\nwhatis expression\n\n   Print the type of the *expression*.\n\nsource expression\n\n   Try to get source code for the given object and display it.\n\n   New in version 3.2.\n\ndisplay [expression]\n\n   Display the value of the expression if it changed, each time\n   execution stops in the current frame.\n\n   Without expression, list all display expressions for the current\n   frame.\n\n   New in version 3.2.\n\nundisplay [expression]\n\n   Do not display the expression any more in the current frame.\n   Without expression, clear all display expressions for the current\n   frame.\n\n   New in version 3.2.\n\ninteract\n\n   Start an interative interpreter (using the "code" module) whose\n   global namespace contains all the (global and local) names found in\n   the current scope.\n\n   New in version 3.2.\n\nalias [name [command]]\n\n   Create an alias called *name* that executes *command*.  The command\n   must *not* be enclosed in quotes.  Replaceable parameters can be\n   indicated by "%1", "%2", and so on, while "%*" is replaced by all\n   the parameters. If no command is given, the current alias for\n   *name* is shown. If no arguments are given, all aliases are listed.\n\n   Aliases may be nested and can contain anything that can be legally\n   typed at the pdb prompt.  Note that internal pdb commands *can* be\n   overridden by aliases.  Such a command is then hidden until the\n   alias is removed.  Aliasing is recursively applied to the first\n   word of the command line; all other words in the line are left\n   alone.\n\n   As an example, here are two useful aliases (especially when placed\n   in the ".pdbrc" file):\n\n      # Print instance variables (usage "pi classInst")\n      alias pi for k in %1.__dict__.keys(): print("%1.",k,"=",%1.__dict__[k])\n      # Print instance variables in self\n      alias ps pi self\n\nunalias name\n\n   Delete the specified alias.\n\n! statement\n\n   Execute the (one-line) *statement* in the context of the current\n   stack frame. The exclamation point can be omitted unless the first\n   word of the statement resembles a debugger command.  To set a\n   global variable, you can prefix the assignment command with a\n   "global" statement on the same line, e.g.:\n\n      (Pdb) global list_options; list_options = [\'-l\']\n      (Pdb)\n\nrun [args ...]\nrestart [args ...]\n\n   Restart the debugged Python program.  If an argument is supplied,\n   it is split with "shlex" and the result is used as the new\n   "sys.argv". History, breakpoints, actions and debugger options are\n   preserved. "restart" is an alias for "run".\n\nq(uit)\n\n   Quit from the debugger.  The program being executed is aborted.\n\n-[ Footnotes ]-\n\n[1] Whether a frame is considered to originate in a certain module is\n    determined by the "__name__" in the frame globals.\n',
+ 'del': '\nThe "del" statement\n*******************\n\n   del_stmt ::= "del" target_list\n\nDeletion is recursively defined very similar to the way assignment is\ndefined. Rather than spelling it out in full details, here are some\nhints.\n\nDeletion of a target list recursively deletes each target, from left\nto right.\n\nDeletion of a name removes the binding of that name from the local or\nglobal namespace, depending on whether the name occurs in a "global"\nstatement in the same code block.  If the name is unbound, a\n"NameError" exception will be raised.\n\nDeletion of attribute references, subscriptions and slicings is passed\nto the primary object involved; deletion of a slicing is in general\nequivalent to assignment of an empty slice of the right type (but even\nthis is determined by the sliced object).\n\nChanged in version 3.2: Previously it was illegal to delete a name\nfrom the local namespace if it occurs as a free variable in a nested\nblock.\n',
+ 'dict': '\nDictionary displays\n*******************\n\nA dictionary display is a possibly empty series of key/datum pairs\nenclosed in curly braces:\n\n   dict_display       ::= "{" [key_datum_list | dict_comprehension] "}"\n   key_datum_list     ::= key_datum ("," key_datum)* [","]\n   key_datum          ::= expression ":" expression\n   dict_comprehension ::= expression ":" expression comp_for\n\nA dictionary display yields a new dictionary object.\n\nIf a comma-separated sequence of key/datum pairs is given, they are\nevaluated from left to right to define the entries of the dictionary:\neach key object is used as a key into the dictionary to store the\ncorresponding datum.  This means that you can specify the same key\nmultiple times in the key/datum list, and the final dictionary\'s value\nfor that key will be the last one given.\n\nA dict comprehension, in contrast to list and set comprehensions,\nneeds two expressions separated with a colon followed by the usual\n"for" and "if" clauses. When the comprehension is run, the resulting\nkey and value elements are inserted in the new dictionary in the order\nthey are produced.\n\nRestrictions on the types of the key values are listed earlier in\nsection *The standard type hierarchy*.  (To summarize, the key type\nshould be *hashable*, which excludes all mutable objects.)  Clashes\nbetween duplicate keys are not detected; the last datum (textually\nrightmost in the display) stored for a given key value prevails.\n',
+ 'dynamic-features': '\nInteraction with dynamic features\n*********************************\n\nThere are several cases where Python statements are illegal when used\nin conjunction with nested scopes that contain free variables.\n\nIf a variable is referenced in an enclosing scope, it is illegal to\ndelete the name.

Names may be resolved in the local\nand global namespaces of the caller.  Free variables are not resolved\nin the nearest enclosing namespace, but in the global namespace.

+ 'exceptions': '\nExceptions\n**********\n\nExceptions are a means of breaking out of the normal flow of control\nof a code block in order to handle errors or other exceptional\nconditions.  An exception is *raised* at the point where the error is\ndetected; it may be *handled* by the surrounding code block or by any\ncode block that directly or indirectly invoked the code block where\nthe error occurred.\n\nThe Python interpreter raises an exception when it detects a run-time\nerror (such as division by zero).  A Python program can also\nexplicitly raise an exception with the "raise" statement. Exception\nhandlers are specified with the "try" ... "except" statement.  The\n"finally" clause of such a statement can be used to specify cleanup\ncode which does not handle the exception, but is executed whether an\nexception occurred or not in the preceding code.\n\nPython uses the "termination" model of error handling: an exception\nhandler can find out what happened and continue execution at an outer\nlevel, but it cannot repair the cause of the error and retry the\nfailing operation (except by re-entering the offending piece of code\nfrom the top).\n\nWhen an exception is not handled at all, the interpreter terminates\nexecution of the program, or returns to its interactive main loop.  In\neither case, it prints a stack backtrace, except when the exception is\n"SystemExit".\n\nExceptions are identified by class instances.  The "except" clause is\nselected depending on the class of the instance: it must reference the\nclass of the instance or a base class thereof.  The instance can be\nreceived by the handler and can carry additional information about the\nexceptional condition.\n\nNote: Exception messages are not part of the Python API.  Their contents\n  may change from one version of Python to the next without warning\n  and should not be relied on by code which will run under multiple\n  versions of the interpreter.\n\nSee also the description of the "try" statement in section *The try\nstatement* and "raise" statement in section *The raise statement*.\n\n-[ Footnotes ]-\n\n[1] This limitation occurs because the code that is executed by these\n    operations is not available at the time the module is compiled.\n',

A frame contains\nsome administrative information (used for debugging) and determines\nwhere and how execution continues after the code block\'s execution has\ncompleted.\n\nA *scope* defines the visibility of a name within a block.  If a local\nvariable is defined in a block, its scope includes that block.  If the\ndefinition occurs in a function block, the scope extends to any blocks\ncontained within the defining one, unless a contained block introduces\na different binding for the name.  The scope of names defined in a\nclass block is limited to the class block; it does not extend to the\ncode blocks of methods -- this includes comprehensions and generator\nexpressions since they are implemented using a function scope.  This\nmeans that the following will fail:\n\n   class A:\n       a = 42\n       b = list(a + i for i in range(10))\n\nWhen a name is used in a code block, it is resolved using the nearest\nenclosing scope.  The set of all such scopes visible to a code block\nis called the block\'s *environment*.\n\nIf a name is bound in a block, it is a local variable of that block,\nunless declared as "nonlocal".  If a name is bound at the module\nlevel, it is a global variable.  (The variables of the module code\nblock are local and global.)  If a variable is used in a code block\nbut not defined there, it is a *free variable*.\n\nWhen a name is not found at all, a "NameError" exception is raised.\nIf the name refers to a local variable that has not been bound, a\n"UnboundLocalError" exception is raised.  "UnboundLocalError" is a\nsubclass of "NameError".\n\nThe following constructs bind names: formal parameters to functions,\n"import" statements, class and function definitions (these bind the\nclass or function name in the defining block), and targets that are\nidentifiers if occurring in an assignment, "for" loop header, or after\n"as" in a "with" statement or "except" clause. The "import" statement\nof the form "from ... import *" binds all names defined in the\nimported module, except those beginning with an underscore.  This form\nmay only be used at the module level.\n\nA target occurring in a "del" statement is also considered bound for\nthis purpose (though the actual semantics are to unbind the name).\n\nEach assignment or import statement occurs within a block defined by a\nclass or function definition or at the module level (the top-level\ncode block).\n\nIf a name binding operation occurs anywhere within a code block, all\nuses of the name within the block are treated as references to the\ncurrent block.  This can lead to errors when a name is used within a\nblock before it is bound.  This rule is subtle.  Python lacks\ndeclarations and allows name binding operations to occur anywhere\nwithin a code block.  The local variables of a code block can be\ndetermined by scanning the entire text of the block for name binding\noperations.\n\nIf the "global" statement occurs within a block, all uses of the name\nspecified in the statement refer to the binding of that name in the\ntop-level namespace.  Names are resolved in the top-level namespace by\nsearching the global namespace, i.e. the namespace of the module\ncontaining the code block, and the builtins namespace, the namespace\nof the module "builtins".  The global namespace is searched first.  If\nthe name is not found there, the builtins namespace is searched.  The\nglobal statement must precede all uses of the name.\n\nThe builtins namespace associated with the execution of a code block\nis actually found by looking up the name "__builtins__" in its global\nnamespace; this should be a dictionary or a module (in the latter case\nthe module\'s dictionary is used).  By default, when in the "__main__"\nmodule, "__builtins__" is the built-in module "builtins"; when in any\nother module, "__builtins__" is an alias for the dictionary of the\n"builtins" module itself.  "__builtins__" can be set to a user-created\ndictionary to create a weak form of restricted execution.\n\n**CPython implementation detail:** Users should not touch\n"__builtins__"; it is strictly an implementation detail.  Users\nwanting to override values in the builtins namespace should "import"\nthe "builtins" module and modify its attributes appropriately.\n\nThe namespace for a module is automatically created the first time a\nmodule is imported.  The main module for a script is always called\n"__main__".\n\nThe "global" statement has the same scope as a name binding operation\nin the same block.  If the nearest enclosing scope for a free variable\ncontains a global statement, the free variable is treated as a global.\n\nA class definition is an executable statement that may use and define\nnames. These references follow the normal rules for name resolution.\nThe namespace of the class definition becomes the attribute dictionary\nof the class.  Names defined at the class scope are not visible in\nmethods.\n\n\nInteraction with dynamic features\n---------------------------------\n\nThere are several cases where Python statements are illegal when used\nin conjunction with nested scopes that contain free variables.\n\nIf a variable is referenced in an enclosing scope, it is illegal to\ndelete the name.  An error will be reported at compile time.\n\nIf the wild card form of import --- "import *" --- is used in a\nfunction and the function contains or is a nested block with free\nvariables, the compiler will raise a "SyntaxError".\n\nThe "eval()" and "exec()" functions do not have access to the full\nenvironment for resolving names.  Names may be resolved in the local\nand global namespaces of the caller.  Free variables are not resolved\nin the nearest enclosing namespace, but in the global namespace.  [1]\nThe "exec()" and "eval()" functions have optional arguments to\noverride the global and local namespace.  If only one namespace is\nspecified, it is used for both.\n\n\nExceptions\n==========\n\nExceptions are a means of breaking out of the normal flow of control\nof a code block in order to handle errors or other exceptional\nconditions.  An exception is *raised* at the point where the error is\ndetected; it may be *handled* by the surrounding code block or by any\ncode block that directly or indirectly invoked the code block where\nthe error occurred.\n\nThe Python interpreter raises an exception when it detects a run-time\nerror (such as division by zero).  A Python program can also\nexplicitly raise an exception with the "raise" statement. Exception\nhandlers are specified with the "try" ... "except" statement.  The\n"finally" clause of such a statement can be used to specify cleanup\ncode which does not handle the exception, but is executed whether an\nexception occurred or not in the preceding code.\n\nPython uses the "termination" model of error handling: an exception\nhandler can find out what happened and continue execution at an outer\nlevel, but it cannot repair the cause of the error and retry the\nfailing operation (except by re-entering the offending piece of code\nfrom the top).\n\nWhen an exception is not handled at all, the interpreter terminates\nexecution of the program, or returns to its interactive main loop.  In\neither case, it prints a stack backtrace, except when the exception is\n"SystemExit".\n\nExceptions are identified by class instances.  The "except" clause is\nselected depending on the class of the instance: it must reference the\nclass of the instance or a base class thereof.  The instance can be\nreceived by the handler and can carry additional information about the\nexceptional condition.\n\nNote: Exception messages are not part of the Python API.  Their contents\n  may change from one version of Python to the next without warning\n  and should not be relied on by code which will run under multiple\n  versions of the interpreter.\n\nSee also the description of the "try" statement in section *The try\nstatement* and "raise" statement in section *The raise statement*.\n\n-[ Footnotes ]-\n\n[1] This limitation occurs because the code that is executed by these\n    operations is not available at the time the module is compiled.\n',
+ 'exprlists': '\nExpression lists\n****************\n\n   expression_list ::= expression ( "," expression )* [","]\n\nAn expression list containing at least one comma yields a tuple.  The\nlength of the tuple is the number of expressions in the list.  The\nexpressions are evaluated from left to right.\n\nThe trailing comma is required only to create a single tuple (a.k.a. a\n*singleton*); it is optional in all other cases.  A single expression\nwithout a trailing comma doesn\'t create a tuple, but rather yields the\nvalue of that expression. (To create an empty tuple, use an empty pair\nof parentheses: "()".)\n',
+ 'floating': '\nFloating point literals\n***********************\n\nFloating point literals are described by the following lexical\ndefinitions:\n\n   floatnumber   ::= pointfloat | exponentfloat\n   pointfloat    ::= [intpart] fraction | intpart "."\n   exponentfloat ::= (intpart | pointfloat) exponent\n   intpart       ::= digit+\n   fraction      ::= "." digit+\n   exponent      ::= ("e" | "E") ["+" | "-"] digit+\n\nNote that the integer and exponent parts are always interpreted using\nradix 10. For example, "077e010" is legal, and denotes the same number\nas "77e10". The allowed range of floating point literals is\nimplementation-dependent. Some examples of floating point literals:\n\n   3.14    10.    .001    1e100    3.14e-10    0e0\n\nNote that numeric literals do not include a sign; a phrase like "-1"\nis actually an expression composed of the unary operator "-" and the\nliteral "1".\n',
+ 'for': '\nThe "for" statement\n*******************\n\nThe "for" statement is used to iterate over the elements of a sequence\n(such as a string, tuple or list) or other iterable object:\n\n   for_stmt ::= "for" target_list "in" expression_list ":" suite\n                ["else" ":" suite]\n\nThe expression list is evaluated once; it should yield an iterable\nobject.  An iterator is created for the result of the\n"expression_list".  The suite is then executed once for each item\nprovided by the iterator, in the order of ascending indices.  Each\nitem in turn is assigned to the target list using the standard rules\nfor assignments (see *Assignment statements*), and then the suite is\nexecuted.  When the items are exhausted (which is immediately when the\nsequence is empty or an iterator raises a "StopIteration" exception),\nthe suite in the "else" clause, if present, is executed, and the loop\nterminates.\n\nA "break" statement executed in the first suite terminates the loop\nwithout executing the "else" clause\'s suite.  A "continue" statement\nexecuted in the first suite skips the rest of the suite and continues\nwith the next item, or with the "else" clause if there was no next\nitem.\n\nThe suite may assign to the variable(s) in the target list; this does\nnot affect the next item assigned to it.\n\nNames in the target list are not deleted when the loop is finished,\nbut if the sequence is empty, it will not have been assigned to at all\nby the loop.  Hint: the built-in function "range()" returns an\niterator of integers suitable to emulate the effect of Pascal\'s "for i\n:= a to b do"; e.g., "list(range(3))" returns the list "[0, 1, 2]".\n\nNote: There is a subtlety when the sequence is being modified by the loop\n  (this can only occur for mutable sequences, i.e. lists).  An\n  internal counter is used to keep track of which item is used next,\n  and this is incremented on each iteration.  When this counter has\n  reached the length of the sequence the loop terminates.  This means\n  that if the suite deletes the current (or a previous) item from the\n  sequence, the next item will be skipped (since it gets the index of\n  the current item which has already been treated).  Likewise, if the\n  suite inserts an item in the sequence before the current item, the\n  current item will be treated again the next time through the loop.\n  This can lead to nasty bugs that can be avoided by making a\n  temporary copy using a slice of the whole sequence, e.g.,\n\n     for x in a[:]:\n         if x < 0: a.remove(x)\n',
+ 'formatstrings': '\nFormat String Syntax\n********************\n\nThe "str.format()" method and the "Formatter" class share the same\nsyntax for format strings (although in the case of "Formatter",\nsubclasses can define their own format string syntax).\n\nFormat strings contain "replacement fields" surrounded by curly braces\n"{}". Anything that is not contained in braces is considered literal\ntext, which is copied unchanged to the output.  If you need to include\na brace character in the literal text, it can be escaped by doubling:\n"{{" and "}}".\n\nThe grammar for a replacement field is as follows:\n\n      replacement_field ::= "{" [field_name] ["!" conversion] [":" format_spec] "}"\n      field_name        ::= arg_name ("." attribute_name | "[" element_index "]")*\n      arg_name          ::= [identifier | integer]\n      attribute_name    ::= identifier\n      element_index     ::= integer | index_string\n      index_string      ::= <any source character except "]"> +\n      conversion        ::= "r" | "s" | "a"\n      format_spec       ::= <described in the next section>\n\nIn less formal terms, the replacement field can start with a\n*field_name* that specifies the object whose value is to be formatted\nand inserted into the output instead of the replacement field. The\n*field_name* is optionally followed by a  *conversion* field, which is\npreceded by an exclamation point "\'!\'", and a *format_spec*, which is\npreceded by a colon "\':\'".  These specify a non-default format for the\nreplacement value.\n\nSee also the *Format Specification Mini-Language* section.\n\nThe *field_name* itself begins with an *arg_name* that is either a\nnumber or a keyword.  If it\'s a number, it refers to a positional\nargument, and if it\'s a keyword, it refers to a named keyword\nargument.  If the numerical arg_names in a format string are 0, 1, 2,\n... in sequence, they can all be omitted (not just some) and the\nnumbers 0, 1, 2, ... will be automatically inserted in that order.\nBecause *arg_name* is not quote-delimited, it is not possible to\nspecify arbitrary dictionary keys (e.g., the strings "\'10\'" or\n"\':-]\'") within a format string. The *arg_name* can be followed by any\nnumber of index or attribute expressions. An expression of the form\n"\'.name\'" selects the named attribute using "getattr()", while an\nexpression of the form "\'[index]\'" does an index lookup using\n"__getitem__()".\n\nChanged in version 3.1: The positional argument specifiers can be\nomitted, so "\'{} {}\'" is equivalent to "\'{0} {1}\'".\n\nSome simple format string examples:\n\n   "First, thou shalt count to {0}" # References first positional argument\n   "Bring me a {}"                  # Implicitly references the first positional argument\n   "From {} to {}"                  # Same as "From {0} to {1}"\n   "My quest is {name}"             # References keyword argument \'name\'\n   "Weight in tons {0.weight}"      # \'weight\' attribute of first positional arg\n   "Units destroyed: {players[0]}"  # First element of keyword argument \'players\'.\n\nThe *conversion* field causes a type coercion before formatting.\nNormally, the job of formatting a value is done by the "__format__()"\nmethod of the value itself.  However, in some cases it is desirable to\nforce a type to be formatted as a string, overriding its own\ndefinition of formatting.  By converting the value to a string before\ncalling "__format__()", the normal formatting logic is bypassed.\n\nThree conversion flags are currently supported: "\'!s\'" which calls\n"str()" on the value, "\'!r\'" which calls "repr()" and "\'!a\'" which\ncalls "ascii()".\n\nSome examples:\n\n   "Harold\'s a clever {0!s}"        # Calls str() on the argument first\n   "Bring out the holy {name!r}"    # Calls repr() on the argument first\n   "More {!a}"                      # Calls ascii() on the argument first\n\nThe *format_spec* field contains a specification of how the value\nshould be presented, including such details as field width, alignment,\npadding, decimal precision and so on.  Each value type can define its\nown "formatting mini-language" or interpretation of the *format_spec*.\n\nMost built-in types support a common formatting mini-language, which\nis described in the next section.\n\nA *format_spec* field can also include nested replacement fields\nwithin it. These nested replacement fields can contain only a field\nname; conversion flags and format specifications are not allowed.  The\nreplacement fields within the format_spec are substituted before the\n*format_spec* string is interpreted. This allows the formatting of a\nvalue to be dynamically specified.\n\nSee the *Format examples* section for some examples.\n\n\nFormat Specification Mini-Language\n==================================\n\n"Format specifications" are used within replacement fields contained\nwithin a format string to define how individual values are presented\n(see *Format String Syntax*).  They can also be passed directly to the\nbuilt-in "format()" function.  Each formattable type may define how\nthe format specification is to be interpreted.\n\nMost built-in types implement the following options for format\nspecifications, although some of the formatting options are only\nsupported by the numeric types.\n\nA general convention is that an empty format string ("""") produces\nthe same result as if you had called "str()" on the value. A non-empty\nformat string typically modifies the result.\n\nThe general form of a *standard format specifier* is:\n\n   format_spec ::= [[fill]align][sign][#][0][width][,][.precision][type]\n   fill        ::= <any character>\n   align       ::= "<" | ">" | "=" | "^"\n   sign        ::= "+" | "-" | " "\n   width       ::= integer\n   precision   ::= integer\n   type        ::= "b" | "c" | "d" | "e" | "E" | "f" | "F" | "g" | "G" | "n" | "o" | "s" | "x" | "X" | "%"\n\nIf a valid *align* value is specified, it can be preceded by a *fill*\ncharacter that can be any character and defaults to a space if\nomitted. Note that it is not possible to use "{" and "}" as *fill*\nchar while using the "str.format()" method; this limitation however\ndoesn\'t affect the "format()" function.\n\nThe meaning of the various alignment options is as follows:\n\n   +-----------+------------------------------------------------------------+\n   | Option    | Meaning                                                    |\n   +===========+============================================================+\n   | "\'<\'"     | Forces the field to be left-aligned within the available   |\n   +-----------+------------------------------------------------------------+\n   | "\'>\'"     | Forces the field to be right-aligned within the available  |\n   +-----------+------------------------------------------------------------+\n   | "\'=\'"     | Forces the padding to be placed after the sign (if any)    |\n   +-----------+------------------------------------------------------------+\n   | "\'^\'"     | Forces the field to be centered within the available       |\n   +-----------+------------------------------------------------------------+\n\nNote that unless a minimum field width is defined, the field width\nwill always be the same size as the data to fill it, so that the\nalignment option has no meaning in this case.\n\nThe *sign* option is only valid for number types, and can be one of\nthe following:\n\n   +-----------+------------------------------------------------------------+\n   | Option    | Meaning                                                    |\n   +===========+============================================================+\n   | "\'+\'"     | indicates that a sign should be used for both positive as  |\n   +-----------+------------------------------------------------------------+\n   | "\'-\'"     | indicates that a sign should be used only for negative     |\n   +-----------+------------------------------------------------------------+\n   | space     | indicates that a leading space should be used on positive  |\n   +-----------+------------------------------------------------------------+\n\nThe "\'#\'" option causes the "alternate form" to be used for the\nconversion.  The alternate form is defined differently for different\ntypes.  This option is only valid for integer, float, complex and\nDecimal types. For integers, when binary, octal, or hexadecimal output\nis used, this option adds the prefix respective "\'0b\'", "\'0o\'", or\n"\'0x\'" to the output value. For floats, complex and Decimal the\nalternate form causes the result of the conversion to always contain a\ndecimal-point character, even if no digits follow it. Normally, a\ndecimal-point character appears in the result of these conversions\nonly if a digit follows it. In addition, for "\'g\'" and "\'G\'"\nconversions, trailing zeros are not removed from the result.\n\nThe "\',\'" option signals the use of a comma for a thousands separator.\nFor a locale aware separator, use the "\'n\'" integer presentation type\ninstead.\n\nChanged in version 3.1: Added the "\',\'" option (see also **PEP 378**).\n\n*width* is a decimal integer defining the minimum field width.  If not\nspecified, then the field width will be determined by the content.\n\nPreceding the *width* field by a zero ("\'0\'") character enables sign-\naware zero-padding for numeric types.  This is equivalent to a *fill*\ncharacter of "\'0\'" with an *alignment* type of "\'=\'".\n\nThe *precision* is a decimal number indicating how many digits should\nbe displayed after the decimal point for a floating point value\nformatted with "\'f\'" and "\'F\'", or before and after the decimal point\nfor a floating point value formatted with "\'g\'" or "\'G\'".  For non-\nnumber types the field indicates the maximum field size - in other\nwords, how many characters will be used from the field content. The\n*precision* is not allowed for integer values.\n\nFinally, the *type* determines how the data should be presented.\n\nThe available string presentation types are:\n\n   +-----------+------------------------------------------------------------+\n   | Type      | Meaning                                                    |\n   +===========+============================================================+\n   | "\'s\'"     | String format.

+ 'function': '\nFunction definitions\n********************\n\nA function definition defines a user-defined function object (see\nsection *The standard type hierarchy*):\n\n   funcdef        ::= [decorators] "def" funcname "(" [parameter_list] ")" ["->" expression] ":" suite\n   decorators     ::= decorator+\n   decorator      ::= "@" dotted_name ["(" [parameter_list [","]] ")"] NEWLINE\n   dotted_name    ::= identifier ("." identifier)*\n   parameter_list ::= (defparameter ",")*\n                      ( "*" [parameter] ("," defparameter)* ["," "**" parameter]\n                      | "**" parameter\n                      | defparameter [","] )\n   parameter      ::= identifier [":" expression]\n   defparameter   ::= parameter ["=" expression]\n   funcname       ::= identifier\n\nA function definition is an executable statement.  Its execution binds\nthe function name in the current local namespace to a function object\n(a wrapper around the executable code for the function).  This\nfunction object contains a reference to the current global namespace\nas the global namespace to be used when the function is called.\n\nThe function definition does not execute the function body; this gets\nexecuted only when the function is called. [3]\n\nA function definition may be wrapped by one or more *decorator*\nexpressions. Decorator expressions are evaluated when the function is\ndefined, in the scope that contains the function definition.  The\nresult must be a callable, which is invoked with the function object\nas the only argument. The returned value is bound to the function name\ninstead of the function object.  Multiple decorators are applied in\nnested fashion. For example, the following code\n\n   @f1(arg)\n   @f2\n   def func(): pass\n\nis equivalent to\n\n   def func(): pass\n   func = f1(arg)(f2(func))\n\nWhen one or more *parameters* have the form *parameter* "="\n*expression*, the function is said to have "default parameter values."\nFor a parameter with a default value, the corresponding *argument* may\nbe omitted from a call, in which case the parameter\'s default value is\nsubstituted.  If a parameter has a default value, all following\nparameters up until the ""*"" must also have a default value --- this\nis a syntactic restriction that is not expressed by the grammar.\n\n**Default parameter values are evaluated from left to right when the\nfunction definition is executed.** This means that the expression is\nevaluated once, when the function is defined, and that the same "pre-\ncomputed" value is used for each call.  This is especially important\nto understand when a default parameter is a mutable object, such as a\nlist or a dictionary: if the function modifies the object (e.g. by\nappending an item to a list), the default value is in effect modified.\nThis is generally not what was intended.  A way around this is to use\n"None" as the default, and explicitly test for it in the body of the\nfunction, e.g.:\n\n   def whats_on_the_telly(penguin=None):\n       if penguin is None:\n           penguin = []\n       penguin.append("property of the zoo")\n       return penguin\n\nFunction call semantics are described in more detail in section\n*Calls*. A function call always assigns values to all parameters\nmentioned in the parameter list, either from position arguments, from\nkeyword arguments, or from default values.  If the form\n""*identifier"" is present, it is initialized to a tuple receiving any\nexcess positional parameters, defaulting to the empty tuple.  If the\nform ""**identifier"" is present, it is initialized to a new\ndictionary receiving any excess keyword arguments, defaulting to a new\nempty dictionary. Parameters after ""*"" or ""*identifier"" are\nkeyword-only parameters and may only be passed used keyword arguments.\n\nParameters may have annotations of the form "": expression"" following\nthe parameter name.  Any parameter may have an annotation even those\nof the form "*identifier" or "**identifier".  Functions may have\n"return" annotation of the form ""-> expression"" after the parameter\nlist.  These annotations can be any valid Python expression and are\nevaluated when the function definition is executed.  Annotations may\nbe evaluated in a different order than they appear in the source code.\nThe presence of annotations does not change the semantics of a\nfunction.  The annotation values are available as values of a\ndictionary keyed by the parameters\' names in the "__annotations__"\nattribute of the function object.\n\nIt is also possible to create anonymous functions (functions not bound\nto a name), for immediate use in expressions.  This uses lambda\nexpressions, described in section *Lambdas*.  Note that the lambda\nexpression is merely a shorthand for a simplified function definition;\na function defined in a ""def"" statement can be passed around or\nassigned to another name just like a function defined by a lambda\nexpression.  The ""def"" form is actually more powerful since it\nallows the execution of multiple statements and annotations.\n\n**Programmer\'s note:** Functions are first-class objects.  A ""def""\nstatement executed inside a function definition defines a local\nfunction that can be returned or passed around.  Free variables used\nin the nested function can access the local variables of the function\ncontaining the def.  See section *Naming and binding* for details.\n\nSee also:\n\n   **PEP 3107** - Function Annotations\n      The original specification for function annotations.\n',
+ 'global': '\nThe "global" statement\n**********************\n\n   global_stmt ::= "global" identifier ("," identifier)*\n\nThe "global" statement is a declaration which holds for the entire\ncurrent code block.  It means that the listed identifiers are to be\ninterpreted as globals.  It would be impossible to assign to a global\nvariable without "global", although free variables may refer to\nglobals without being declared global.\n\nNames listed in a "global" statement must not be used in the same code\nblock textually preceding that "global" statement.\n\nNames listed in a "global" statement must not be defined as formal\nparameters or in a "for" loop control target, "class" definition,\nfunction definition, or "import" statement.\n\n**CPython implementation detail:** The current implementation does not\nenforce the latter two restrictions, but programs should not abuse\nthis freedom, as future implementations may enforce them or silently\nchange the meaning of the program.\n\n**Programmer\'s note:** the "global" is a directive to the parser.  It\napplies only to code parsed at the same time as the "global"\nstatement. In particular, a "global" statement contained in a string\nor code object supplied to the built-in "exec()" function does not\naffect the code block *containing* the function call, and code\ncontained in such a string is unaffected by "global" statements in the\ncode containing the function call.  The same applies to the "eval()"\nand "compile()" functions.\n',

Note that failures in this step may\nindicate either that the module could not be located, *or* that an\nerror occurred while initializing the module, which includes execution\nof the module\'s code.\n\nIf the requested module is retrieved successfully, it will be made\navailable in the local namespace in one of three ways:\n\n* If the module name is followed by "as", then the name following "as"\n  is bound directly to the imported module.\n\n* If no other name is specified, and the module being imported is a\n  top level module, the module\'s name is bound in the local namespace\n  as a reference to the imported module\n\n* If the module being imported is *not* a top level module, then the\n  name of the top level package that contains the module is bound in\n  the local namespace as a reference to the top level package. The\n  imported module must be accessed using its full qualified name\n  rather than directly\n\nThe "from" form uses a slightly more complex process:\n\n1. find the module specified in the "from" clause loading and\n   initializing it if necessary;\n\n2. for each of the identifiers specified in the "import" clauses:\n\n   1. check if the imported module has an attribute by that name\n\n   2. if not, attempt to import a submodule with that name and then\n      check the imported module again for that attribute\n\n   3. if the attribute is not found, "ImportError" is raised.\n\n   4. otherwise, a reference to that value is bound in the local\n      namespace, using the name in the "as" clause if it is present,\n      otherwise using the attribute name\n\nExamples:\n\n   import foo                 # foo imported and bound locally\n   import foo.bar.baz         # foo.bar.baz imported, foo bound locally\n   import foo.bar.baz as fbb  # foo.bar.baz imported and bound as fbb\n   from foo.bar import baz    # foo.bar.baz imported and bound as baz\n   from foo import attr       # foo imported and foo.attr bound as attr\n\nIf the list of identifiers is replaced by a star ("\'*\'"), all public\nnames defined in the module are bound in the local namespace for the\nscope where the "import" statement occurs.\n\nThe *public names* defined by a module are determined by checking the\nmodule\'s namespace for a variable named "__all__"; if defined, it must\nbe a sequence of strings which are names defined or imported by that\nmodule.  The names given in "__all__" are all considered public and\nare required to exist.  If "__all__" is not defined, the set of public\nnames includes all names found in the module\'s namespace which do not\nbegin with an underscore character ("\'_\'").  "__all__" should contain\nthe entire public API. It is intended to avoid accidentally exporting\nitems that are not part of the API (such as library modules which were\nimported and used within the module).\n\nThe "from" form with "*" may only occur in a module scope.  The wild\ncard form of import --- "import *" --- is only allowed at the module\nlevel. Attempting to use it in class or function definitions will\nraise a "SyntaxError".\n\nWhen specifying what module to import you do not have to specify the\nabsolute name of the module. When a module or package is contained\nwithin another package it is possible to make a relative import within\nthe same top package without having to mention the package name. By\nusing leading dots in the specified module or package after "from" you\ncan specify how high to traverse up the current package hierarchy\nwithout specifying exact names. One leading dot means the current\npackage where the module making the import exists. Two dots means up\none package level. Three dots is up two levels, etc. So if you execute\n"from . import mod" from a module in the "pkg" package then you will\nend up importing "pkg.mod". If you execute "from ..subpkg2 import mod"\nfrom within "pkg.subpkg1" you will import "pkg.subpkg2.mod". The\nspecification for relative imports is contained within **PEP 328**.\n\n"importlib.import_module()" is provided to support applications that\ndetermine which modules need to be loaded dynamically.\n\n\nFuture statements\n=================\n\nA *future statement* is a directive to the compiler that a particular\nmodule should be compiled using syntax or semantics that will be\navailable in a specified future release of Python.  The future\nstatement is intended to ease migration to future versions of Python\nthat introduce incompatible changes to the language.

They are all redundant because\nthey are always enabled, and only kept for backwards compatibility.\n\nA future statement is recognized and treated specially at compile\ntime: Changes to the semantics of core constructs are often\nimplemented by generating different code.  It may even be the case\nthat a new feature introduces new incompatible syntax (such as a new\nreserved word), in which case the compiler may need to parse the\nmodule differently.  Such decisions cannot be pushed off until\nruntime.\n\nFor any given release, the compiler knows which feature names have\nbeen defined, and raises a compile-time error if a future statement\ncontains a feature not known to it.\n\nThe direct runtime semantics are the same as for any import statement:\nthere is a standard module "__future__", described later, and it will\nbe imported in the usual way at the time the future statement is\nexecuted.\n\nThe interesting runtime semantics depend on the specific feature\nenabled by the future statement.\n\nNote that there is nothing special about the statement:\n\n   import __future__ [as name]\n\nThat is not a future statement; it\'s an ordinary import statement with\nno special semantics or syntax restrictions.\n\nCode compiled by calls to the built-in functions "exec()" and\n"compile()" that occur in a module "M" containing a future statement\nwill, by default, use the new syntax or semantics associated with the\nfuture statement.  This can be controlled by optional arguments to\n"compile()" --- see the documentation of that function for details.\n\nA future statement typed at an interactive interpreter prompt will\ntake effect for the rest of the interpreter session.  If an\ninterpreter is started with the *-i* option, is passed a script name\nto execute, and the script includes a future statement, it will be in\neffect in the interactive session started after the script is\nexecuted.\n\nSee also:\n\n   **PEP 236** - Back to the __future__\n      The original proposal for the __future__ mechanism.\n',
+ 'in': '\nComparisons\n***********\n\nUnlike C, all comparison operations in Python have the same priority,\nwhich is lower than that of any arithmetic, shifting or bitwise\noperation.  Also unlike C, expressions like "a < b < c" have the\ninterpretation that is conventional in mathematics:\n\n   comparison    ::= or_expr ( comp_operator or_expr )*\n   comp_operator ::= "<" | ">" | "==" | ">=" | "<=" | "!="\n                     | "is" ["not"] | ["not"] "in"\n\nComparisons yield boolean values: "True" or "False".\n\nComparisons can be chained arbitrarily, e.g., "x < y <= z" is\nequivalent to "x < y and y <= z", except that "y" is evaluated only\nonce (but in both cases "z" is not evaluated at all when "x < y" is\nfound to be false).\n\nFormally, if *a*, *b*, *c*, ..., *y*, *z* are expressions and *op1*,\n*op2*, ..., *opN* are comparison operators, then "a op1 b op2 c ... y\nopN z" is equivalent to "a op1 b and b op2 c and ... y opN z", except\nthat each expression is evaluated at most once.\n\nNote that "a op1 b op2 c" doesn\'t imply any kind of comparison between\n*a* and *c*, so that, e.g., "x < y > z" is perfectly legal (though\nperhaps not pretty).\n\nThe operators "<", ">", "==", ">=", "<=", and "!=" compare the values\nof two objects.  The objects need not have the same type. If both are\nnumbers, they are converted to a common type.  Otherwise, the "==" and\n"!=" operators *always* consider objects of different types to be\nunequal, while the "<", ">", ">=" and "<=" operators raise a\n"TypeError" when comparing objects of different types that do not\nimplement these operators for the given pair of types.  You can\ncontrol comparison behavior of objects of non-built-in types by\ndefining rich comparison methods like "__gt__()", described in section\n*Basic customization*.\n\nComparison of objects of the same type depends on the type:\n\n* Numbers are compared arithmetically.\n\n* The values "float(\'NaN\')" and "Decimal(\'NaN\')" are special. The are\n  identical to themselves, "x is x" but are not equal to themselves,\n  "x != x".  Additionally, comparing any value to a not-a-number value\n  will return "False".  For example, both "3 < float(\'NaN\')" and\n  "float(\'NaN\') < 3" will return "False".\n\n* Bytes objects are compared lexicographically using the numeric\n  values of their elements.\n\n* Strings are compared lexicographically using the numeric equivalents\n  (the result of the built-in function "ord()") of their characters.\n  [3] String and bytes object can\'t be compared!\n\n* Tuples and lists are compared lexicographically using comparison of\n  corresponding elements.  This means that to compare equal, each\n  element must compare equal and the two sequences must be of the same\n  type and have the same length.\n\n  If not equal, the sequences are ordered the same as their first\n  differing elements.  For example, "[1,2,x] <= [1,2,y]" has the same\n  value as "x <= y".  If the corresponding element does not exist, the\n  shorter sequence is ordered first (for example, "[1,2] < [1,2,3]").\n\n* Mappings (dictionaries) compare equal if and only if they have the\n  same "(key, value)" pairs. Order comparisons "(\'<\', \'<=\', \'>=\',\n  \'>\')" raise "TypeError".\n\n* Sets and frozensets define comparison operators to mean subset and\n  superset tests.  Those relations do not define total orderings (the\n  two sets "{1,2}" and {2,3} are not equal, nor subsets of one\n  another, nor supersets of one another).  Accordingly, sets are not\n  appropriate arguments for functions which depend on total ordering.\n  For example, "min()", "max()", and "sorted()" produce undefined\n  results given a list of sets as inputs.\n\n* Most other objects of built-in types compare unequal unless they are\n  the same object; the choice whether one object is considered smaller\n  or larger than another one is made arbitrarily but consistently\n  within one execution of a program.\n\nComparison of objects of the differing types depends on whether either\nof the types provide explicit support for the comparison.  Most\nnumeric types can be compared with one another.  When cross-type\ncomparison is not supported, the comparison method returns\n"NotImplemented".\n\nThe operators "in" and "not in" test for membership.  "x in s"\nevaluates to true if *x* is a member of *s*, and false otherwise.  "x\nnot in s" returns the negation of "x in s".  All built-in sequences\nand set types support this as well as dictionary, for which "in" tests\nwhether a the dictionary has a given key. For container types such as\nlist, tuple, set, frozenset, dict, or collections.deque, the\nexpression "x in y" is equivalent to "any(x is e or x == e for e in\ny)".\n\nFor the string and bytes types, "x in y" is true if and only if *x* is\na substring of *y*.  An equivalent test is "y.find(x) != -1".  Empty\nstrings are always considered to be a substring of any other string,\nso """ in "abc"" will return "True".\n\nFor user-defined classes which define the "__contains__()" method, "x\nin y" is true if and only if "y.__contains__(x)" is true.\n\nFor user-defined classes which do not define "__contains__()" but do\ndefine "__iter__()", "x in y" is true if some value "z" with "x == z"\nis produced while iterating over "y".  If an exception is raised\nduring the iteration, it is as if "in" raised that exception.\n\nLastly, the old-style iteration protocol is tried: if a class defines\n"__getitem__()", "x in y" is true if and only if there is a non-\nnegative integer index *i* such that "x == y[i]", and all lower\ninteger indices do not raise "IndexError" exception.  (If any other\nexception is raised, it is as if "in" raised that exception).\n\nThe operator "not in" is defined to have the inverse true value of\n"in".\n\nThe operators "is" and "is not" test for object identity: "x is y" is\ntrue if and only if *x* and *y* are the same object.  "x is not y"\nyields the inverse truth value. [4]\n',

+ 'naming': '\nNaming and binding\n******************\n\n*Names* refer to objects.  Names are introduced by name binding\noperations. Each occurrence of a name in the program text refers to\nthe *binding* of that name established in the innermost function block\ncontaining the use.\n\nA *block* is a piece of Python program text that is executed as a\nunit. The following are blocks: a module, a function body, and a class\ndefinition. Each command typed interactively is a block.  A script\nfile (a file given as standard input to the interpreter or specified\non the interpreter command line the first argument) is a code block.\nA script command (a command specified on the interpreter command line\nwith the \'**-c**\' option) is a code block.  The string argument passed\nto the built-in functions "eval()" and "exec()" is a code block.\n\nA code block is executed in an *execution frame*.  A frame contains\nsome administrative information (used for debugging) and determines\nwhere and how execution continues after the code block\'s execution has\ncompleted.\n\nA *scope* defines the visibility of a name within a block.  If a local\nvariable is defined in a block, its scope includes that block.  If the\ndefinition occurs in a function block, the scope extends to any blocks\ncontained within the defining one, unless a contained block introduces\na different binding for the name.  The scope of names defined in a\nclass block is limited to the class block; it does not extend to the\ncode blocks of methods -- this includes comprehensions and generator\nexpressions since they are implemented using a function scope.  This\nmeans that the following will fail:\n\n   class A:\n       a = 42\n       b = list(a + i for i in range(10))\n\nWhen a name is used in a code block, it is resolved using the nearest\nenclosing scope.  The set of all such scopes visible to a code block\nis called the block\'s *environment*.\n\nIf a name is bound in a block, it is a local variable of that block,\nunless declared as "nonlocal".  If a name is bound at the module\nlevel, it is a global variable.  (The variables of the module code\nblock are local and global.)  If a variable is used in a code block\nbut not defined there, it is a *free variable*.\n\nWhen a name is not found at all, a "NameError" exception is raised.\nIf the name refers to a local variable that has not been bound, a\n"UnboundLocalError" exception is raised.  "UnboundLocalError" is a\nsubclass of "NameError".\n\nThe following constructs bind names: formal parameters to functions,\n"import" statements, class and function definitions (these bind the\nclass or function name in the defining block), and targets that are\nidentifiers if occurring in an assignment, "for" loop header, or after\n"as" in a "with" statement or "except" clause. The "import" statement\nof the form "from ... import *" binds all names defined in the\nimported module, except those beginning with an underscore.  This form\nmay only be used at the module level.\n\nA target occurring in a "del" statement is also considered bound for\nthis purpose (though the actual semantics are to unbind the name).\n\nEach assignment or import statement occurs within a block defined by a\nclass or function definition or at the module level (the top-level\ncode block).\n\nIf a name binding operation occurs anywhere within a code block, all\nuses of the name within the block are treated as references to the\ncurrent block.  This can lead to errors when a name is used within a\nblock before it is bound.  This rule is subtle.  Python lacks\ndeclarations and allows name binding operations to occur anywhere\nwithin a code block.  The local variables of a code block can be\ndetermined by scanning the entire text of the block for name binding\noperations.\n\nIf the "global" statement occurs within a block, all uses of the name\nspecified in the statement refer to the binding of that name in the\ntop-level namespace.  Names are resolved in the top-level namespace by\nsearching the global namespace, i.e. the namespace of the module\ncontaining the code block, and the builtins namespace, the namespace\nof the module "builtins".  The global namespace is searched first.  If\nthe name is not found there, the builtins namespace is searched.  The\nglobal statement must precede all uses of the name.\n\nThe builtins namespace associated with the execution of a code block\nis actually found by looking up the name "__builtins__" in its global\nnamespace; this should be a dictionary or a module (in the latter case\nthe module\'s dictionary is used).  By default, when in the "__main__"\nmodule, "__builtins__" is the built-in module "builtins"; when in any\nother module, "__builtins__" is an alias for the dictionary of the\n"builtins" module itself.  "__builtins__" can be set to a user-created\ndictionary to create a weak form of restricted execution.\n\n**CPython implementation detail:** Users should not touch\n"__builtins__"; it is strictly an implementation detail.  Users\nwanting to override values in the builtins namespace should "import"\nthe "builtins" module and modify its attributes appropriately.\n\nThe namespace for a module is automatically created the first time a\nmodule is imported.  The main module for a script is always called\n"__main__".\n\nThe "global" statement has the same scope as a name binding operation\nin the same block.  If the nearest enclosing scope for a free variable\ncontains a global statement, the free variable is treated as a global.\n\nA class definition is an executable statement that may use and define\nnames. These references follow the normal rules for name resolution.\nThe namespace of the class definition becomes the attribute dictionary\nof the class.  Names defined at the class scope are not visible in\nmethods.\n\n\nInteraction with dynamic features\n=================================\n\nThere are several cases where Python statements are illegal when used\nin conjunction with nested scopes that contain free variables.\n\nIf a variable is referenced in an enclosing scope, it is illegal to\ndelete the name.  An error will be reported at compile time.\n\nIf the wild card form of import --- "import *" --- is used in a\nfunction and the function contains or is a nested block with free\nvariables, the compiler will raise a "SyntaxError".\n\nThe "eval()" and "exec()" functions do not have access to the full\nenvironment for resolving names.  Names may be resolved in the local\nand global namespaces of the caller.  Free variables are not resolved\nin the nearest enclosing namespace, but in the global namespace.  [1]\nThe "exec()" and "eval()" functions have optional arguments to\noverride the global and local namespace.  If only one namespace is\nspecified, it is used for both.\n',
+ 'nonlocal': '\nThe "nonlocal" statement\n************************\n\n   nonlocal_stmt ::= "nonlocal" identifier ("," identifier)*\n\nThe "nonlocal" statement causes the listed identifiers to refer to\npreviously bound variables in the nearest enclosing scope.  This is\nimportant because the default behavior for binding is to search the\nlocal namespace first.  The statement allows encapsulated code to\nrebind variables outside of the local scope besides the global\n(module) scope.\n\nNames listed in a "nonlocal" statement, unlike to those listed in a\n"global" statement, must refer to pre-existing bindings in an\nenclosing scope (the scope in which a new binding should be created\ncannot be determined unambiguously).\n\nNames listed in a "nonlocal" statement must not collide with pre-\nexisting bindings in the local scope.\n\nSee also:\n\n   **PEP 3104** - Access to Names in Outer Scopes\n      The specification for the "nonlocal" statement.\n',

For instance, to evaluate the\n   expression "x + y", where *x* is an instance of a class that has an\n   "__add__()" method, "x.__add__(y)" is called.  The "__divmod__()"\n   method should be the equivalent to using "__floordiv__()" and\n   "__mod__()"; it should not be related to "__truediv__()".  Note\n   that "__pow__()" should be defined to accept an optional third\n   argument if the ternary version of the built-in "pow()" function is\n   to be supported.\n\n   If one of those methods does not support the operation with the\n   supplied arguments, it should return "NotImplemented".\n\nobject.__radd__(self, other)\nobject.__rsub__(self, other)\nobject.__rmul__(self, other)\nobject.__rtruediv__(self, other)\nobject.__rfloordiv__(self, other)\nobject.__rmod__(self, other)\nobject.__rdivmod__(self, other)\nobject.__rpow__(self, other)\nobject.__rlshift__(self, other)\nobject.__rrshift__(self, other)\nobject.__rand__(self, other)\nobject.__rxor__(self, other)\nobject.__ror__(self, other)\n\n   These methods are called to implement the binary arithmetic\n   operations ("+", "-", "*", "/", "//", "%", "divmod()", "pow()",\n   "**", "<<", ">>", "&", "^", "|") with reflected (swapped) operands.\n   These functions are only called if the left operand does not\n   support the corresponding operation and the operands are of\n   different types. [2]  For instance, to evaluate the expression "x -\n   y", where *y* is an instance of a class that has an "__rsub__()"\n   method, "y.__rsub__(x)" is called if "x.__sub__(y)" returns\n   *NotImplemented*.\n\n   Note that ternary "pow()" will not try calling "__rpow__()" (the\n   coercion rules would become too complicated).\n\n   Note: If the right operand\'s type is a subclass of the left operand\'s\n     type and that subclass provides the reflected method for the\n     operation, this method will be called before the left operand\'s\n     non-reflected method.

Otherwise, "x.__add__(y)" and "y.__radd__(x)" are considered, as\n   with the evaluation of "x + y". In certain situations, augmented\n   assignment can result in unexpected errors (see *Why does\n   a_tuple[i] += [\'item\'] raise an exception when the addition\n   works?*), but this behavior is in fact part of the data model.\n\nobject.__neg__(self)\nobject.__pos__(self)\nobject.__abs__(self)\nobject.__invert__(self)\n\n   Called to implement the unary arithmetic operations ("-", "+",\n   "abs()" and "~").\n\nobject.__complex__(self)\nobject.__int__(self)\nobject.__float__(self)\nobject.__round__(self[, n])\n\n   Called to implement the built-in functions "complex()", "int()",\n   "float()" and "round()".

+ 'objects': '\nObjects, values and types\n*************************\n\n*Objects* are Python\'s abstraction for data.  All data in a Python\nprogram is represented by objects or by relations between objects. (In\na sense, and in conformance to Von Neumann\'s model of a "stored\nprogram computer," code is also represented by objects.)\n\nEvery object has an identity, a type and a value.  An object\'s\n*identity* never changes once it has been created; you may think of it\nas the object\'s address in memory.  The \'"is"\' operator compares the\nidentity of two objects; the "id()" function returns an integer\nrepresenting its identity.\n\n**CPython implementation detail:** For CPython, "id(x)" is the memory\naddress where "x" is stored.\n\nAn object\'s type determines the operations that the object supports\n(e.g., "does it have a length?") and also defines the possible values\nfor objects of that type.  The "type()" function returns an object\'s\ntype (which is an object itself).  Like its identity, an object\'s\n*type* is also unchangeable. [1]\n\nThe *value* of some objects can change.  Objects whose value can\nchange are said to be *mutable*; objects whose value is unchangeable\nonce they are created are called *immutable*. (The value of an\nimmutable container object that contains a reference to a mutable\nobject can change when the latter\'s value is changed; however the\ncontainer is still considered immutable, because the collection of\nobjects it contains cannot be changed.  So, immutability is not\nstrictly the same as having an unchangeable value, it is more subtle.)\nAn object\'s mutability is determined by its type; for instance,\nnumbers, strings and tuples are immutable, while dictionaries and\nlists are mutable.\n\nObjects are never explicitly destroyed; however, when they become\nunreachable they may be garbage-collected.  An implementation is\nallowed to postpone garbage collection or omit it altogether --- it is\na matter of implementation quality how garbage collection is\nimplemented, as long as no objects are collected that are still\nreachable.\n\n**CPython implementation detail:** CPython currently uses a reference-\ncounting scheme with (optional) delayed detection of cyclically linked\ngarbage, which collects most objects as soon as they become\nunreachable, but is not guaranteed to collect garbage containing\ncircular references.  See the documentation of the "gc" module for\ninformation on controlling the collection of cyclic garbage. Other\nimplementations act differently and CPython may change. Do not depend\non immediate finalization of objects when they become unreachable (ex:\nalways close files).\n\nNote that the use of the implementation\'s tracing or debugging\nfacilities may keep objects alive that would normally be collectable.\nAlso note that catching an exception with a \'"try"..."except"\'\nstatement may keep objects alive.\n\nSome objects contain references to "external" resources such as open\nfiles or windows.  It is understood that these resources are freed\nwhen the object is garbage-collected, but since garbage collection is\nnot guaranteed to happen, such objects also provide an explicit way to\nrelease the external resource, usually a "close()" method. Programs\nare strongly recommended to explicitly close such objects.  The\n\'"try"..."finally"\' statement and the \'"with"\' statement provide\nconvenient ways to do this.\n\nSome objects contain references to other objects; these are called\n*containers*. Examples of containers are tuples, lists and\ndictionaries.  The references are part of a container\'s value.  In\nmost cases, when we talk about the value of a container, we imply the\nvalues, not the identities of the contained objects; however, when we\ntalk about the mutability of a container, only the identities of the\nimmediately contained objects are implied.  So, if an immutable\ncontainer (like a tuple) contains a reference to a mutable object, its\nvalue changes if that mutable object is changed.\n\nTypes affect almost all aspects of object behavior.  Even the\nimportance of object identity is affected in some sense: for immutable\ntypes, operations that compute new values may actually return a\nreference to any existing object with the same type and value, while\nfor mutable objects this is not allowed.  E.g., after "a = 1; b = 1",\n"a" and "b" may or may not refer to the same object with the value\none, depending on the implementation, but after "c = []; d = []", "c"\nand "d" are guaranteed to refer to two different, unique, newly\ncreated empty lists.

For example, and\n    assuming a platform on which a Python float is an IEEE 754 double-\n    precision number, in order that "-1e-100 % 1e100" have the same\n    sign as "1e100", the computed result is "-1e-100 + 1e100", which\n    is numerically exactly equal to "1e100".  The function\n    "math.fmod()" returns a result whose sign matches the sign of the\n    first argument instead, and so returns "-1e-100" in this case.\n    Which approach is more appropriate depends on the application.\n\n[2] If x is very close to an exact integer multiple of y, it\'s\n    possible for "x//y" to be one larger than "(x-x%y)//y" due to\n    rounding.  In such cases, Python returns the latter result, in\n    order to preserve that "divmod(x,y)[0] * y + x % y" be very close\n    to "x".\n\n[3] While comparisons between strings make sense at the byte level,\n    they may be counter-intuitive to users.  For example, the strings\n    ""\\u00C7"" and ""\\u0327\\u0043"" compare differently, even though\n    they both represent the same unicode character (LATIN CAPITAL\n    LETTER C WITH CEDILLA).  To compare strings in a human\n    recognizable way, compare using "unicodedata.normalize()".\n\n[4] Due to automatic garbage-collection, free lists, and the dynamic\n    nature of descriptors, you may notice seemingly unusual behaviour\n    in certain uses of the "is" operator, like those involving\n    comparisons between instance methods, or constants.  Check their\n    documentation for more info.\n\n[5] The "%" operator is also used for string formatting; the same\n    precedence applies.\n\n[6] The power operator "**" binds less tightly than an arithmetic or\n    bitwise unary operator on its right, that is, "2**-1" is "0.5".\n',
+ 'pass': '\nThe "pass" statement\n********************\n\n   pass_stmt ::= "pass"\n\n"pass" is a null operation --- when it is executed, nothing happens.\nIt is useful as a placeholder when a statement is required\nsyntactically, but no code needs to be executed, for example:\n\n   def f(arg): pass    # a function that does nothing (yet)\n\n   class C: pass       # a class with no methods (yet)\n',
+ 'power': '\nThe power operator\n******************\n\nThe power operator binds more tightly than unary operators on its\nleft; it binds less tightly than unary operators on its right.  The\nsyntax is:\n\n   power ::= primary ["**" u_expr]\n\nThus, in an unparenthesized sequence of power and unary operators, the\noperators are evaluated from right to left (this does not constrain\nthe evaluation order for the operands): "-1**2" results in "-1".\n\nThe power operator has the same semantics as the built-in "pow()"\nfunction, when called with two arguments: it yields its left argument\nraised to the power of its right argument.  The numeric arguments are\nfirst converted to a common type, and the result is of that type.\n\nFor int operands, the result has the same type as the operands unless\nthe second argument is negative; in that case, all arguments are\nconverted to float and a float result is delivered. For example,\n"10**2" returns "100", but "10**-2" returns "0.01".\n\nRaising "0.0" to a negative power results in a "ZeroDivisionError".\nRaising a negative number to a fractional power results in a "complex"\nnumber. (In earlier versions it raised a "ValueError".)\n',
+ 'raise': '\nThe "raise" statement\n*********************\n\n   raise_stmt ::= "raise" [expression ["from" expression]]\n\nIf no expressions are present, "raise" re-raises the last exception\nthat was active in the current scope.  If no exception is active in\nthe current scope, a "RuntimeError" exception is raised indicating\nthat this is an error.\n\nOtherwise, "raise" evaluates the first expression as the exception\nobject.  It must be either a subclass or an instance of\n"BaseException". If it is a class, the exception instance will be\nobtained when needed by instantiating the class with no arguments.\n\nThe *type* of the exception is the exception instance\'s class, the\n*value* is the instance itself.\n\nA traceback object is normally created automatically when an exception\nis raised and attached to it as the "__traceback__" attribute, which\nis writable. You can create an exception and set your own traceback in\none step using the "with_traceback()" exception method (which returns\nthe same exception instance, with its traceback set to its argument),\nlike so:\n\n   raise Exception("foo occurred").with_traceback(tracebackobj)\n\nThe "from" clause is used for exception chaining: if given, the second\n*expression* must be another exception class or instance, which will\nthen be attached to the raised exception as the "__cause__" attribute\n(which is writable).  If the raised exception is not handled, both\nexceptions will be printed:\n\n   >>> try:\n   ...     print(1 / 0)\n   ... except Exception as exc:\n   ...     raise RuntimeError("Something bad happened") from exc\n   ...\n   Traceback (most recent call last):\n     File "<stdin>", line 2, in <module>\n   ZeroDivisionError: int division or modulo by zero\n\n   The above exception was the direct cause of the following exception:\n\n   Traceback (most recent call last):\n     File "<stdin>", line 4, in <module>\n   RuntimeError: Something bad happened\n\nA similar mechanism works implicitly if an exception is raised inside\nan exception handler: the previous exception is then attached as the\nnew exception\'s "__context__" attribute:\n\n   >>> try:\n   ...     print(1 / 0)\n   ... except:\n   ...     raise RuntimeError("Something bad happened")\n   ...\n   Traceback (most recent call last):\n     File "<stdin>", line 2, in <module>\n   ZeroDivisionError: int division or modulo by zero\n\n   During handling of the above exception, another exception occurred:\n\n   Traceback (most recent call last):\n     File "<stdin>", line 4, in <module>\n   RuntimeError: Something bad happened\n\nAdditional information on exceptions can be found in section\n*Exceptions*, and information about handling exceptions is in section\n*The try statement*.\n',

The\nreturned value (if any) is used as an argument to construct\n"StopIteration" and becomes the "StopIteration.value" attribute.\n',
+ 'sequence-types': '\nEmulating container types\n*************************\n\nThe following methods can be defined to implement container objects.\nContainers usually are sequences (such as lists or tuples) or mappings\n(like dictionaries), but can represent other containers as well.  The\nfirst set of methods is used either to emulate a sequence or to\nemulate a mapping; the difference is that for a sequence, the\nallowable keys should be the integers *k* for which "0 <= k < N" where\n*N* is the length of the sequence, or slice objects, which define a\nrange of items.  It is also recommended that mappings provide the\nmethods "keys()", "values()", "items()", "get()", "clear()",\n"setdefault()", "pop()", "popitem()", "copy()", and "update()"\nbehaving similar to those for Python\'s standard dictionary objects.\nThe "collections" module provides a "MutableMapping" abstract base\nclass to help create those methods from a base set of "__getitem__()",\n"__setitem__()", "__delitem__()", and "keys()". Mutable sequences\nshould provide methods "append()", "count()", "index()", "extend()",\n"insert()", "pop()", "remove()", "reverse()" and "sort()", like Python\nstandard list objects.  Finally, sequence types should implement\naddition (meaning concatenation) and multiplication (meaning\nrepetition) by defining the methods "__add__()", "__radd__()",\n"__iadd__()", "__mul__()", "__rmul__()" and "__imul__()" described\nbelow; they should not define other numerical operators.  It is\nrecommended that both mappings and sequences implement the\n"__contains__()" method to allow efficient use of the "in" operator;\nfor mappings, "in" should search the mapping\'s keys; for sequences, it\nshould search through the values.  It is further recommended that both\nmappings and sequences implement the "__iter__()" method to allow\nefficient iteration through the container; for mappings, "__iter__()"\nshould be the same as "keys()"; for sequences, it should iterate\nthrough the values.\n\nobject.__len__(self)\n\n   Called to implement the built-in function "len()".  Should return\n   the length of the object, an integer ">=" 0.  Also, an object that\n   doesn\'t define a "__bool__()" method and whose "__len__()" method\n   returns zero is considered to be false in a Boolean context.\n\nobject.__length_hint__(self)\n\n   Called to implement "operator.length_hint()". Should return an\n   estimated length for the object (which may be greater or less than\n   the actual length). The length must be an integer ">=" 0. This\n   method is purely an optimization and is never required for\n   correctness.\n\n   New in version 3.4.\n\nNote: Slicing is done exclusively with the following three methods.  A\n  call like\n\n     a[1:2] = b\n\n  is translated to\n\n     a[slice(1, 2, None)] = b\n\n  and so forth.  Missing slice items are always filled in with "None".\n\nobject.__getitem__(self, key)\n\n   Called to implement evaluation of "self[key]". For sequence types,\n   the accepted keys should be integers and slice objects.  Note that\n   the special interpretation of negative indexes (if the class wishes\n   to emulate a sequence type) is up to the "__getitem__()" method. If\n   *key* is of an inappropriate type, "TypeError" may be raised; if of\n   a value outside the set of indexes for the sequence (after any\n   special interpretation of negative values), "IndexError" should be\n   raised. For mapping types, if *key* is missing (not in the\n   container), "KeyError" should be raised.\n\n   Note: "for" loops expect that an "IndexError" will be raised for\n     illegal indexes to allow proper detection of the end of the\n     sequence.\n\nobject.__setitem__(self, key, value)\n\n   Called to implement assignment to "self[key]".  Same note as for\n   "__getitem__()".  This should only be implemented for mappings if\n   the objects support changes to the values for keys, or if new keys\n   can be added, or for sequences if elements can be replaced.  The\n   same exceptions should be raised for improper *key* values as for\n   the "__getitem__()" method.\n\nobject.__delitem__(self, key)\n\n   Called to implement deletion of "self[key]".  Same note as for\n   "__getitem__()".  This should only be implemented for mappings if\n   the objects support removal of keys, or for sequences if elements\n   can be removed from the sequence.  The same exceptions should be\n   raised for improper *key* values as for the "__getitem__()" method.\n\nobject.__iter__(self)\n\n   This method is called when an iterator is required for a container.\n   This method should return a new iterator object that can iterate\n   over all the objects in the container.  For mappings, it should\n   iterate over the keys of the container, and should also be made\n   available as the method "keys()".\n\n   Iterator objects also need to implement this method; they are\n   required to return themselves.  For more information on iterator\n   objects, see *Iterator Types*.\n\nobject.__reversed__(self)\n\n   Called (if present) by the "reversed()" built-in to implement\n   reverse iteration.  It should return a new iterator object that\n   iterates over all the objects in the container in reverse order.\n\n   If the "__reversed__()" method is not provided, the "reversed()"\n   built-in will fall back to using the sequence protocol ("__len__()"\n   and "__getitem__()").  Objects that support the sequence protocol\n   should only provide "__reversed__()" if they can provide an\n   implementation that is more efficient than the one provided by\n   "reversed()".\n\nThe membership test operators ("in" and "not in") are normally\nimplemented as an iteration through a sequence.  However, container\nobjects can supply the following special method with a more efficient\nimplementation, which also does not require the object be a sequence.\n\nobject.__contains__(self, item)\n\n   Called to implement membership test operators.  Should return true\n   if *item* is in *self*, false otherwise.  For mapping objects, this\n   should consider the keys of the mapping rather than the values or\n   the key-item pairs.\n\n   For objects that don\'t define "__contains__()", the membership test\n   first tries iteration via "__iter__()", then the old sequence\n   iteration protocol via "__getitem__()", see *this section in the\n   language reference*.\n',
+ 'shifting': '\nShifting operations\n*******************\n\nThe shifting operations have lower priority than the arithmetic\noperations:\n\n   shift_expr ::= a_expr | shift_expr ( "<<" | ">>" ) a_expr\n\nThese operators accept integers as arguments.  They shift the first\nargument to the left or right by the number of bits given by the\nsecond argument.\n\nA right shift by *n* bits is defined as floor division by "pow(2,n)".\nA left shift by *n* bits is defined as multiplication with "pow(2,n)".\n\nNote: In the current implementation, the right-hand operand is required to\n  be at most "sys.maxsize".  If the right-hand operand is larger than\n  "sys.maxsize" an "OverflowError" exception is raised.\n',
+ 'slicings': '\nSlicings\n********\n\nA slicing selects a range of items in a sequence object (e.g., a\nstring, tuple or list).  Slicings may be used as expressions or as\ntargets in assignment or "del" statements.  The syntax for a slicing:\n\n   slicing      ::= primary "[" slice_list "]"\n   slice_list   ::= slice_item ("," slice_item)* [","]\n   slice_item   ::= expression | proper_slice\n   proper_slice ::= [lower_bound] ":" [upper_bound] [ ":" [stride] ]\n   lower_bound  ::= expression\n   upper_bound  ::= expression\n   stride       ::= expression\n\nThere is ambiguity in the formal syntax here: anything that looks like\nan expression list also looks like a slice list, so any subscription\ncan be interpreted as a slicing.  Rather than further complicating the\nsyntax, this is disambiguated by defining that in this case the\ninterpretation as a subscription takes priority over the\ninterpretation as a slicing (this is the case if the slice list\ncontains no proper slice).\n\nThe semantics for a slicing are as follows.  The primary must evaluate\nto a mapping object, and it is indexed (using the same "__getitem__()"\nmethod as normal subscription) with a key that is constructed from the\nslice list, as follows.  If the slice list contains at least one\ncomma, the key is a tuple containing the conversion of the slice\nitems; otherwise, the conversion of the lone slice item is the key.\nThe conversion of a slice item that is an expression is that\nexpression.  The conversion of a proper slice is a slice object (see\nsection *The standard type hierarchy*) whose "start", "stop" and\n"step" attributes are the values of the expressions given as lower\nbound, upper bound and stride, respectively, substituting "None" for\nmissing expressions.\n',
+ 'specialattrs': '\nSpecial Attributes\n******************\n\nThe implementation adds a few special read-only attributes to several\nobject types, where they are relevant.  Some of these are not reported\nby the "dir()" built-in function.\n\nobject.__dict__\n\n   A dictionary or other mapping object used to store an object\'s\n   (writable) attributes.\n\ninstance.__class__\n\n   The class to which a class instance belongs.\n\nclass.__bases__\n\n   The tuple of base classes of a class object.\n\nclass.__name__\n\n   The name of the class or type.\n\nclass.__qualname__\n\n   The *qualified name* of the class or type.\n\n   New in version 3.3.\n\nclass.__mro__\n\n   This attribute is a tuple of classes that are considered when\n   looking for base classes during method resolution.\n\nclass.mro()\n\n   This method can be overridden by a metaclass to customize the\n   method resolution order for its instances.  It is called at class\n   instantiation, and its result is stored in "__mro__".\n\nclass.__subclasses__()\n\n   Each class keeps a list of weak references to its immediate\n   subclasses.  This method returns a list of all those references\n   still alive. Example:\n\n      >>> int.__subclasses__()\n      [<class \'bool\'>]\n\n-[ Footnotes ]-\n\n[1] Additional information on these special methods may be found in\n    the Python Reference Manual (*Basic customization*).\n\n[2] As a consequence, the list "[1, 2]" is considered equal to "[1.0,\n    2.0]", and similarly for tuples.\n\n[3] They must have since the parser can\'t tell the type of the\n    operands.\n\n[4] Cased characters are those with general category property being\n    one of "Lu" (Letter, uppercase), "Ll" (Letter, lowercase), or "Lt"\n    (Letter, titlecase).\n\n[5] To format only a tuple you should therefore provide a singleton\n    tuple whose only element is the tuple to be formatted.\n',
+ 'specialnames': '\nSpecial method names\n********************\n\nA class can implement certain operations that are invoked by special\nsyntax (such as arithmetic operations or subscripting and slicing) by\ndefining methods with special names. This is Python\'s approach to\n*operator overloading*, allowing classes to define their own behavior\nwith respect to language operators.  For instance, if a class defines\na method named "__getitem__()", and "x" is an instance of this class,\nthen "x[i]" is roughly equivalent to "type(x).__getitem__(x, i)".\nExcept where mentioned, attempts to execute an operation raise an\nexception when no appropriate method is defined (typically\n"AttributeError" or "TypeError").\n\nWhen implementing a class that emulates any built-in type, it is\nimportant that the emulation only be implemented to the degree that it\nmakes sense for the object being modelled.  For example, some\nsequences may work well with retrieval of individual elements, but\nextracting a slice may not make sense.  (One example of this is the\n"NodeList" interface in the W3C\'s Document Object Model.)\n\n\nBasic customization\n===================\n\nobject.__new__(cls[, ...])\n\n   Called to create a new instance of class *cls*.  "__new__()" is a\n   static method (special-cased so you need not declare it as such)\n   that takes the class of which an instance was requested as its\n   first argument.  The remaining arguments are those passed to the\n   object constructor expression (the call to the class).  The return\n   value of "__new__()" should be the new object instance (usually an\n   instance of *cls*).\n\n   Typical implementations create a new instance of the class by\n   invoking the superclass\'s "__new__()" method using\n   "super(currentclass, cls).__new__(cls[, ...])" with appropriate\n   arguments and then modifying the newly-created instance as\n   necessary before returning it.\n\n   If "__new__()" returns an instance of *cls*, then the new\n   instance\'s "__init__()" method will be invoked like\n   "__init__(self[, ...])", where *self* is the new instance and the\n   remaining arguments are the same as were passed to "__new__()".\n\n   If "__new__()" does not return an instance of *cls*, then the new\n   instance\'s "__init__()" method will not be invoked.\n\n   "__new__()" is intended mainly to allow subclasses of immutable\n   types (like int, str, or tuple) to customize instance creation.  It\n   is also commonly overridden in custom metaclasses in order to\n   customize class creation.\n\nobject.__init__(self[, ...])\n\n   Called when the instance is created.  The arguments are those\n   passed to the class constructor expression.  If a base class has an\n   "__init__()" method, the derived class\'s "__init__()" method, if\n   any, must explicitly call it to ensure proper initialization of the\n   base class part of the instance; for example:\n   "BaseClass.__init__(self, [args...])".  As a special constraint on\n   constructors, no value may be returned; doing so will cause a\n   "TypeError" to be raised at runtime.\n\nobject.__del__(self)\n\n   Called when the instance is about to be destroyed.  This is also\n   called a destructor.  If a base class has a "__del__()" method, the\n   derived class\'s "__del__()" method, if any, must explicitly call it\n   to ensure proper deletion of the base class part of the instance.\n   Note that it is possible (though not recommended!) for the\n   "__del__()" method to postpone destruction of the instance by\n   creating a new reference to it.  It may then be called at a later\n   time when this new reference is deleted.  It is not guaranteed that\n   "__del__()" methods are called for objects that still exist when\n   the interpreter exits.\n\n   Note: "del x" doesn\'t directly call "x.__del__()" --- the former\n     decrements the reference count for "x" by one, and the latter is\n     only called when "x"\'s reference count reaches zero.  Some common\n     situations that may prevent the reference count of an object from\n     going to zero include: circular references between objects (e.g.,\n     a doubly-linked list or a tree data structure with parent and\n     child pointers); a reference to the object on the stack frame of\n     a function that caught an exception (the traceback stored in\n     "sys.exc_info()[2]" keeps the stack frame alive); or a reference\n     to the object on the stack frame that raised an unhandled\n     exception in interactive mode (the traceback stored in\n     "sys.last_traceback" keeps the stack frame alive).  The first\n     situation can only be remedied by explicitly breaking the cycles;\n     the latter two situations can be resolved by storing "None" in\n     "sys.last_traceback". Circular references which are garbage are\n     detected and cleaned up when the cyclic garbage collector is\n     enabled (it\'s on by default). Refer to the documentation for the\n     "gc" module for more information about this topic.\n\n   Warning: Due to the precarious circumstances under which "__del__()"\n     methods are invoked, exceptions that occur during their execution\n     are ignored, and a warning is printed to "sys.stderr" instead.\n     Also, when "__del__()" is invoked in response to a module being\n     deleted (e.g., when execution of the program is done), other\n     globals referenced by the "__del__()" method may already have\n     been deleted or in the process of being torn down (e.g. the\n     import machinery shutting down).  For this reason, "__del__()"\n     methods should do the absolute minimum needed to maintain\n     external invariants.  Starting with version 1.5, Python\n     guarantees that globals whose name begins with a single\n     underscore are deleted from their module before other globals are\n     deleted; if no other references to such globals exist, this may\n     help in assuring that imported modules are still available at the\n     time when the "__del__()" method is called.\n\nobject.__repr__(self)\n\n   Called by the "repr()" built-in function to compute the "official"\n   string representation of an object.  If at all possible, this\n   should look like a valid Python expression that could be used to\n   recreate an object with the same value (given an appropriate\n   environment).  If this is not possible, a string of the form\n   "<...some useful description...>" should be returned. The return\n   value must be a string object. If a class defines "__repr__()" but\n   not "__str__()", then "__repr__()" is also used when an "informal"\n   string representation of instances of that class is required.\n\n   This is typically used for debugging, so it is important that the\n   representation is information-rich and unambiguous.\n\nobject.__str__(self)\n\n   Called by "str(object)" and the built-in functions "format()" and\n   "print()" to compute the "informal" or nicely printable string\n   representation of an object.  The return value must be a *string*\n   object.\n\n   This method differs from "object.__repr__()" in that there is no\n   expectation that "__str__()" return a valid Python expression: a\n   more convenient or concise representation can be used.\n\n   The default implementation defined by the built-in type "object"\n   calls "object.__repr__()".\n\nobject.__bytes__(self)\n\n   Called by "bytes()" to compute a byte-string representation of an\n   object. This should return a "bytes" object.\n\nobject.__format__(self, format_spec)\n\n   Called by the "format()" built-in function (and by extension, the\n   "str.format()" method of class "str") to produce a "formatted"\n   string representation of an object. The "format_spec" argument is a\n   string that contains a description of the formatting options\n   desired. The interpretation of the "format_spec" argument is up to\n   the type implementing "__format__()", however most classes will\n   either delegate formatting to one of the built-in types, or use a\n   similar formatting option syntax.\n\n   See *Format Specification Mini-Language* for a description of the\n   standard formatting syntax.\n\n   The return value must be a string object.\n\n   Changed in version 3.4: The __format__ method of "object" itself\n   raises a "TypeError" if passed any non-empty string.\n\nobject.__lt__(self, other)\nobject.__le__(self, other)\nobject.__eq__(self, other)\nobject.__ne__(self, other)\nobject.__gt__(self, other)\nobject.__ge__(self, other)\n\n   These are the so-called "rich comparison" methods. The\n   correspondence between operator symbols and method names is as\n   follows: "x<y" calls "x.__lt__(y)", "x<=y" calls "x.__le__(y)",\n   "x==y" calls "x.__eq__(y)", "x!=y" calls "x.__ne__(y)", "x>y" calls\n   "x.__gt__(y)", and "x>=y" calls "x.__ge__(y)".\n\n   A rich comparison method may return the singleton "NotImplemented"\n   if it does not implement the operation for a given pair of\n   arguments. By convention, "False" and "True" are returned for a\n   successful comparison. However, these methods can return any value,\n   so if the comparison operator is used in a Boolean context (e.g.,\n   in the condition of an "if" statement), Python will call "bool()"\n   on the value to determine if the result is true or false.\n\n   There are no implied relationships among the comparison operators.\n   The truth of "x==y" does not imply that "x!=y" is false.\n   Accordingly, when defining "__eq__()", one should also define\n   "__ne__()" so that the operators will behave as expected.  See the\n   paragraph on "__hash__()" for some important notes on creating\n   *hashable* objects which support custom comparison operations and\n   are usable as dictionary keys.\n\n   There are no swapped-argument versions of these methods (to be used\n   when the left argument does not support the operation but the right\n   argument does); rather, "__lt__()" and "__gt__()" are each other\'s\n   reflection, "__le__()" and "__ge__()" are each other\'s reflection,\n   and "__eq__()" and "__ne__()" are their own reflection.\n\n   Arguments to rich comparison methods are never coerced.\n\n   To automatically generate ordering operations from a single root\n   operation, see "functools.total_ordering()".\n\nobject.__hash__(self)\n\n   Called by built-in function "hash()" and for operations on members\n   of hashed collections including "set", "frozenset", and "dict".\n   "__hash__()" should return an integer.  The only required property\n   is that objects which compare equal have the same hash value; it is\n   advised to somehow mix together (e.g. using exclusive or) the hash\n   values for the components of the object that also play a part in\n   comparison of objects.\n\n   Note: "hash()" truncates the value returned from an object\'s custom\n     "__hash__()" method to the size of a "Py_ssize_t".  This is\n     typically 8 bytes on 64-bit builds and 4 bytes on 32-bit builds.\n     If an object\'s   "__hash__()" must interoperate on builds of\n     different bit sizes, be sure to check the width on all supported\n     builds.  An easy way to do this is with "python -c "import sys;\n     print(sys.hash_info.width)""\n\n   If a class does not define an "__eq__()" method it should not\n   define a "__hash__()" operation either; if it defines "__eq__()"\n   but not "__hash__()", its instances will not be usable as items in\n   hashable collections.  If a class defines mutable objects and\n   implements an "__eq__()" method, it should not implement\n   "__hash__()", since the implementation of hashable collections\n   requires that a key\'s hash value is immutable (if the object\'s hash\n   value changes, it will be in the wrong hash bucket).\n\n   User-defined classes have "__eq__()" and "__hash__()" methods by\n   default; with them, all objects compare unequal (except with\n   themselves) and "x.__hash__()" returns an appropriate value such\n   that "x == y" implies both that "x is y" and "hash(x) == hash(y)".\n\n   A class that overrides "__eq__()" and does not define "__hash__()"\n   will have its "__hash__()" implicitly set to "None".  When the\n   "__hash__()" method of a class is "None", instances of the class\n   will raise an appropriate "TypeError" when a program attempts to\n   retrieve their hash value, and will also be correctly identified as\n   unhashable when checking "isinstance(obj, collections.Hashable").\n\n   If a class that overrides "__eq__()" needs to retain the\n   implementation of "__hash__()" from a parent class, the interpreter\n   must be told this explicitly by setting "__hash__ =\n   <ParentClass>.__hash__".\n\n   If a class that does not override "__eq__()" wishes to suppress\n   hash support, it should include "__hash__ = None" in the class\n   definition. A class which defines its own "__hash__()" that\n   explicitly raises a "TypeError" would be incorrectly identified as\n   hashable by an "isinstance(obj, collections.Hashable)" call.\n\n   Note: By default, the "__hash__()" values of str, bytes and datetime\n     objects are "salted" with an unpredictable random value.\n     Although they remain constant within an individual Python\n     process, they are not predictable between repeated invocations of\n     Python.This is intended to provide protection against a denial-\n     of-service caused by carefully-chosen inputs that exploit the\n     worst case performance of a dict insertion, O(n^2) complexity.\n     See http://www.ocert.org/advisories/ocert-2011-003.html for\n     details.Changing hash values affects the iteration order of\n     dicts, sets and other mappings.  Python has never made guarantees\n     about this ordering (and it typically varies between 32-bit and\n     64-bit builds).See also "PYTHONHASHSEED".\n\n   Changed in version 3.3: Hash randomization is enabled by default.\n\nobject.__bool__(self)\n\n   Called to implement truth value testing and the built-in operation\n   "bool()"; should return "False" or "True".  When this method is not\n   defined, "__len__()" is called, if it is defined, and the object is\n   considered true if its result is nonzero.  If a class defines\n   neither "__len__()" nor "__bool__()", all its instances are\n   considered true.\n\n\nCustomizing attribute access\n============================\n\nThe following methods can be defined to customize the meaning of\nattribute access (use of, assignment to, or deletion of "x.name") for\nclass instances.\n\nobject.__getattr__(self, name)\n\n   Called when an attribute lookup has not found the attribute in the\n   usual places (i.e. it is not an instance attribute nor is it found\n   in the class tree for "self").  "name" is the attribute name. This\n   method should return the (computed) attribute value or raise an\n   "AttributeError" exception.\n\n   Note that if the attribute is found through the normal mechanism,\n   "__getattr__()" is not called.  (This is an intentional asymmetry\n   between "__getattr__()" and "__setattr__()".) This is done both for\n   efficiency reasons and because otherwise "__getattr__()" would have\n   no way to access other attributes of the instance.  Note that at\n   least for instance variables, you can fake total control by not\n   inserting any values in the instance attribute dictionary (but\n   instead inserting them in another object).  See the\n   "__getattribute__()" method below for a way to actually get total\n   control over attribute access.\n\nobject.__getattribute__(self, name)\n\n   Called unconditionally to implement attribute accesses for\n   instances of the class. If the class also defines "__getattr__()",\n   the latter will not be called unless "__getattribute__()" either\n   calls it explicitly or raises an "AttributeError". This method\n   should return the (computed) attribute value or raise an\n   "AttributeError" exception. In order to avoid infinite recursion in\n   this method, its implementation should always call the base class\n   method with the same name to access any attributes it needs, for\n   example, "object.__getattribute__(self, name)".\n\n   Note: This method may still be bypassed when looking up special methods\n     as the result of implicit invocation via language syntax or\n     built-in functions. See *Special method lookup*.\n\nobject.__setattr__(self, name, value)\n\n   Called when an attribute assignment is attempted.  This is called\n   instead of the normal mechanism (i.e. store the value in the\n   instance dictionary). *name* is the attribute name, *value* is the\n   value to be assigned to it.\n\n   If "__setattr__()" wants to assign to an instance attribute, it\n   should call the base class method with the same name, for example,\n   "object.__setattr__(self, name, value)".\n\nobject.__delattr__(self, name)\n\n   Like "__setattr__()" but for attribute deletion instead of\n   assignment.  This should only be implemented if "del obj.name" is\n   meaningful for the object.\n\nobject.__dir__(self)\n\n   Called when "dir()" is called on the object. A sequence must be\n   returned. "dir()" converts the returned sequence to a list and\n   sorts it.\n\n\nImplementing Descriptors\n------------------------\n\nThe following methods only apply when an instance of the class\ncontaining the method (a so-called *descriptor* class) appears in an\n*owner* class (the descriptor must be in either the owner\'s class\ndictionary or in the class dictionary for one of its parents).  In the\nexamples below, "the attribute" refers to the attribute whose name is\nthe key of the property in the owner class\' "__dict__".\n\nobject.__get__(self, instance, owner)\n\n   Called to get the attribute of the owner class (class attribute\n   access) or of an instance of that class (instance attribute\n   access). *owner* is always the owner class, while *instance* is the\n   instance that the attribute was accessed through, or "None" when\n   the attribute is accessed through the *owner*.  This method should\n   return the (computed) attribute value or raise an "AttributeError"\n   exception.\n\nobject.__set__(self, instance, value)\n\n   Called to set the attribute on an instance *instance* of the owner\n   class to a new value, *value*.\n\nobject.__delete__(self, instance)\n\n   Called to delete the attribute on an instance *instance* of the\n   owner class.\n\nThe attribute "__objclass__" is interpreted by the "inspect" module as\nspecifying the class where this object was defined (setting this\nappropriately can assist in runtime introspection of dynamic class\nattributes). For callables, it may indicate that an instance of the\ngiven type (or a subclass) is expected or required as the first\npositional argument (for example, CPython sets this attribute for\nunbound methods that are implemented in C).\n\n\nInvoking Descriptors\n--------------------\n\nIn general, a descriptor is an object attribute with "binding\nbehavior", one whose attribute access has been overridden by methods\nin the descriptor protocol:  "__get__()", "__set__()", and\n"__delete__()". If any of those methods are defined for an object, it\nis said to be a descriptor.\n\nThe default behavior for attribute access is to get, set, or delete\nthe attribute from an object\'s dictionary. For instance, "a.x" has a\nlookup chain starting with "a.__dict__[\'x\']", then\n"type(a).__dict__[\'x\']", and continuing through the base classes of\n"type(a)" excluding metaclasses.\n\nHowever, if the looked-up value is an object defining one of the\ndescriptor methods, then Python may override the default behavior and\ninvoke the descriptor method instead.  Where this occurs in the\nprecedence chain depends on which descriptor methods were defined and\nhow they were called.\n\nThe starting point for descriptor invocation is a binding, "a.x". How\nthe arguments are assembled depends on "a":\n\nDirect Call\n   The simplest and least common call is when user code directly\n   invokes a descriptor method:    "x.__get__(a)".\n\nInstance Binding\n   If binding to an object instance, "a.x" is transformed into the\n   call: "type(a).__dict__[\'x\'].__get__(a, type(a))".\n\nClass Binding\n   If binding to a class, "A.x" is transformed into the call:\n   "A.__dict__[\'x\'].__get__(None, A)".\n\nSuper Binding\n   If "a" is an instance of "super", then the binding "super(B,\n   obj).m()" searches "obj.__class__.__mro__" for the base class "A"\n   immediately preceding "B" and then invokes the descriptor with the\n   call: "A.__dict__[\'m\'].__get__(obj, obj.__class__)".\n\nFor instance bindings, the precedence of descriptor invocation depends\non the which descriptor methods are defined.  A descriptor can define\nany combination of "__get__()", "__set__()" and "__delete__()".  If it\ndoes not define "__get__()", then accessing the attribute will return\nthe descriptor object itself unless there is a value in the object\'s\ninstance dictionary.  If the descriptor defines "__set__()" and/or\n"__delete__()", it is a data descriptor; if it defines neither, it is\na non-data descriptor.  Normally, data descriptors define both\n"__get__()" and "__set__()", while non-data descriptors have just the\n"__get__()" method.  Data descriptors with "__set__()" and "__get__()"\ndefined always override a redefinition in an instance dictionary.  In\ncontrast, non-data descriptors can be overridden by instances.\n\nPython methods (including "staticmethod()" and "classmethod()") are\nimplemented as non-data descriptors.  Accordingly, instances can\nredefine and override methods.  This allows individual instances to\nacquire behaviors that differ from other instances of the same class.\n\nThe "property()" function is implemented as a data descriptor.\nAccordingly, instances cannot override the behavior of a property.\n\n\n__slots__\n---------\n\nBy default, instances of classes have a dictionary for attribute\nstorage.  This wastes space for objects having very few instance\nvariables.  The space consumption can become acute when creating large\nnumbers of instances.\n\nThe default can be overridden by defining *__slots__* in a class\ndefinition. The *__slots__* declaration takes a sequence of instance\nvariables and reserves just enough space in each instance to hold a\nvalue for each variable.  Space is saved because *__dict__* is not\ncreated for each instance.\n\nobject.__slots__\n\n   This class variable can be assigned a string, iterable, or sequence\n   of strings with variable names used by instances.  If defined in a\n   class, *__slots__* reserves space for the declared variables and\n   prevents the automatic creation of *__dict__* and *__weakref__* for\n   each instance.\n\n\nNotes on using *__slots__*\n~~~~~~~~~~~~~~~~~~~~~~~~~~\n\n* When inheriting from a class without *__slots__*, the *__dict__*\n  attribute of that class will always be accessible, so a *__slots__*\n  definition in the subclass is meaningless.\n\n* Without a *__dict__* variable, instances cannot be assigned new\n  variables not listed in the *__slots__* definition.  Attempts to\n  assign to an unlisted variable name raises "AttributeError". If\n  dynamic assignment of new variables is desired, then add\n  "\'__dict__\'" to the sequence of strings in the *__slots__*\n  declaration.\n\n* Without a *__weakref__* variable for each instance, classes defining\n  *__slots__* do not support weak references to its instances. If weak\n  reference support is needed, then add "\'__weakref__\'" to the\n  sequence of strings in the *__slots__* declaration.\n\n* *__slots__* are implemented at the class level by creating\n  descriptors (*Implementing Descriptors*) for each variable name.  As\n  a result, class attributes cannot be used to set default values for\n  instance variables defined by *__slots__*; otherwise, the class\n  attribute would overwrite the descriptor assignment.\n\n* The action of a *__slots__* declaration is limited to the class\n  where it is defined.  As a result, subclasses will have a *__dict__*\n  unless they also define *__slots__* (which must only contain names\n  of any *additional* slots).\n\n* If a class defines a slot also defined in a base class, the instance\n  variable defined by the base class slot is inaccessible (except by\n  retrieving its descriptor directly from the base class). This\n  renders the meaning of the program undefined.  In the future, a\n  check may be added to prevent this.\n\n* Nonempty *__slots__* does not work for classes derived from\n  "variable-length" built-in types such as "int", "bytes" and "tuple".\n\n* Any non-string iterable may be assigned to *__slots__*. Mappings may\n  also be used; however, in the future, special meaning may be\n  assigned to the values corresponding to each key.\n\n* *__class__* assignment works only if both classes have the same\n  *__slots__*.\n\n\nCustomizing class creation\n==========================\n\nBy default, classes are constructed using "type()". The class body is\nexecuted in a new namespace and the class name is bound locally to the\nresult of "type(name, bases, namespace)".\n\nThe class creation process can be customised by passing the\n"metaclass" keyword argument in the class definition line, or by\ninheriting from an existing class that included such an argument. In\nthe following example, both "MyClass" and "MySubclass" are instances\nof "Meta":\n\n   class Meta(type):\n       pass\n\n   class MyClass(metaclass=Meta):\n       pass\n\n   class MySubclass(MyClass):\n       pass\n\nAny other keyword arguments that are specified in the class definition\nare passed through to all metaclass operations described below.\n\nWhen a class definition is executed, the following steps occur:\n\n* the appropriate metaclass is determined\n\n* the class namespace is prepared\n\n* the class body is executed\n\n* the class object is created\n\n\nDetermining the appropriate metaclass\n-------------------------------------\n\nThe appropriate metaclass for a class definition is determined as\nfollows:\n\n* if no bases and no explicit metaclass are given, then "type()" is\n  used\n\n* if an explicit metaclass is given and it is *not* an instance of\n  "type()", then it is used directly as the metaclass\n\n* if an instance of "type()" is given as the explicit metaclass, or\n  bases are defined, then the most derived metaclass is used\n\nThe most derived metaclass is selected from the explicitly specified\nmetaclass (if any) and the metaclasses (i.e. "type(cls)") of all\nspecified base classes. The most derived metaclass is one which is a\nsubtype of *all* of these candidate metaclasses. If none of the\ncandidate metaclasses meets that criterion, then the class definition\nwill fail with "TypeError".\n\n\nPreparing the class namespace\n-----------------------------\n\nOnce the appropriate metaclass has been identified, then the class\nnamespace is prepared. If the metaclass has a "__prepare__" attribute,\nit is called as "namespace = metaclass.__prepare__(name, bases,\n**kwds)" (where the additional keyword arguments, if any, come from\nthe class definition).\n\nIf the metaclass has no "__prepare__" attribute, then the class\nnamespace is initialised as an empty "dict()" instance.\n\nSee also:\n\n   **PEP 3115** - Metaclasses in Python 3000\n      Introduced the "__prepare__" namespace hook\n\n\nExecuting the class body\n------------------------\n\nThe class body is executed (approximately) as "exec(body, globals(),\nnamespace)". The key difference from a normal call to "exec()" is that\nlexical scoping allows the class body (including any methods) to\nreference names from the current and outer scopes when the class\ndefinition occurs inside a function.\n\nHowever, even when the class definition occurs inside the function,\nmethods defined inside the class still cannot see names defined at the\nclass scope. Class variables must be accessed through the first\nparameter of instance or class methods, and cannot be accessed at all\nfrom static methods.\n\n\nCreating the class object\n-------------------------\n\nOnce the class namespace has been populated by executing the class\nbody, the class object is created by calling "metaclass(name, bases,\nnamespace, **kwds)" (the additional keywords passed here are the same\nas those passed to "__prepare__").\n\nThis class object is the one that will be referenced by the zero-\nargument form of "super()". "__class__" is an implicit closure\nreference created by the compiler if any methods in a class body refer\nto either "__class__" or "super". This allows the zero argument form\nof "super()" to correctly identify the class being defined based on\nlexical scoping, while the class or instance that was used to make the\ncurrent call is identified based on the first argument passed to the\nmethod.\n\nAfter the class object is created, it is passed to the class\ndecorators included in the class definition (if any) and the resulting\nobject is bound in the local namespace as the defined class.\n\nSee also:\n\n   **PEP 3135** - New super\n      Describes the implicit "__class__" closure reference\n\n\nMetaclass example\n-----------------\n\nThe potential uses for metaclasses are boundless. Some ideas that have\nbeen explored include logging, interface checking, automatic\ndelegation, automatic property creation, proxies, frameworks, and\nautomatic resource locking/synchronization.\n\nHere is an example of a metaclass that uses an\n"collections.OrderedDict" to remember the order that class members\nwere defined:\n\n   class OrderedClass(type):\n\n        @classmethod\n        def __prepare__(metacls, name, bases, **kwds):\n           return collections.OrderedDict()\n\n        def __new__(cls, name, bases, namespace, **kwds):\n           result = type.__new__(cls, name, bases, dict(namespace))\n           result.members = tuple(namespace)\n           return result\n\n   class A(metaclass=OrderedClass):\n       def one(self): pass\n       def two(self): pass\n       def three(self): pass\n       def four(self): pass\n\n   >>> A.members\n   (\'__module__\', \'one\', \'two\', \'three\', \'four\')\n\nWhen the class definition for *A* gets executed, the process begins\nwith calling the metaclass\'s "__prepare__()" method which returns an\nempty "collections.OrderedDict".  That mapping records the methods and\nattributes of *A* as they are defined within the body of the class\nstatement. Once those definitions are executed, the ordered dictionary\nis fully populated and the metaclass\'s "__new__()" method gets\ninvoked.  That method builds the new type and it saves the ordered\ndictionary keys in an attribute called "members".\n\n\nCustomizing instance and subclass checks\n========================================\n\nThe following methods are used to override the default behavior of the\n"isinstance()" and "issubclass()" built-in functions.\n\nIn particular, the metaclass "abc.ABCMeta" implements these methods in\norder to allow the addition of Abstract Base Classes (ABCs) as\n"virtual base classes" to any class or type (including built-in\ntypes), including other ABCs.\n\nclass.__instancecheck__(self, instance)\n\n   Return true if *instance* should be considered a (direct or\n   indirect) instance of *class*. If defined, called to implement\n   "isinstance(instance, class)".\n\nclass.__subclasscheck__(self, subclass)\n\n   Return true if *subclass* should be considered a (direct or\n   indirect) subclass of *class*.  If defined, called to implement\n   "issubclass(subclass, class)".\n\nNote that these methods are looked up on the type (metaclass) of a\nclass.  They cannot be defined as class methods in the actual class.\nThis is consistent with the lookup of special methods that are called\non instances, only in this case the instance is itself a class.\n\nSee also:\n\n   **PEP 3119** - Introducing Abstract Base Classes\n      Includes the specification for customizing "isinstance()" and\n      "issubclass()" behavior through "__instancecheck__()" and\n      "__subclasscheck__()", with motivation for this functionality in\n      the context of adding Abstract Base Classes (see the "abc"\n      module) to the language.\n\n\nEmulating callable objects\n==========================\n\nobject.__call__(self[, args...])\n\n   Called when the instance is "called" as a function; if this method\n   is defined, "x(arg1, arg2, ...)" is a shorthand for\n   "x.__call__(arg1, arg2, ...)".\n\n\nEmulating container types\n=========================\n\nThe following methods can be defined to implement container objects.\nContainers usually are sequences (such as lists or tuples) or mappings\n(like dictionaries), but can represent other containers as well.  The\nfirst set of methods is used either to emulate a sequence or to\nemulate a mapping; the difference is that for a sequence, the\nallowable keys should be the integers *k* for which "0 <= k < N" where\n*N* is the length of the sequence, or slice objects, which define a\nrange of items.  It is also recommended that mappings provide the\nmethods "keys()", "values()", "items()", "get()", "clear()",\n"setdefault()", "pop()", "popitem()", "copy()", and "update()"\nbehaving similar to those for Python\'s standard dictionary objects.\nThe "collections" module provides a "MutableMapping" abstract base\nclass to help create those methods from a base set of "__getitem__()",\n"__setitem__()", "__delitem__()", and "keys()". Mutable sequences\nshould provide methods "append()", "count()", "index()", "extend()",\n"insert()", "pop()", "remove()", "reverse()" and "sort()", like Python\nstandard list objects.  Finally, sequence types should implement\naddition (meaning concatenation) and multiplication (meaning\nrepetition) by defining the methods "__add__()", "__radd__()",\n"__iadd__()", "__mul__()", "__rmul__()" and "__imul__()" described\nbelow; they should not define other numerical operators.  It is\nrecommended that both mappings and sequences implement the\n"__contains__()" method to allow efficient use of the "in" operator;\nfor mappings, "in" should search the mapping\'s keys; for sequences, it\nshould search through the values.  It is further recommended that both\nmappings and sequences implement the "__iter__()" method to allow\nefficient iteration through the container; for mappings, "__iter__()"\nshould be the same as "keys()"; for sequences, it should iterate\nthrough the values.\n\nobject.__len__(self)\n\n   Called to implement the built-in function "len()".  Should return\n   the length of the object, an integer ">=" 0.  Also, an object that\n   doesn\'t define a "__bool__()" method and whose "__len__()" method\n   returns zero is considered to be false in a Boolean context.\n\nobject.__length_hint__(self)\n\n   Called to implement "operator.length_hint()". Should return an\n   estimated length for the object (which may be greater or less than\n   the actual length). The length must be an integer ">=" 0. This\n   method is purely an optimization and is never required for\n   correctness.\n\n   New in version 3.4.\n\nNote: Slicing is done exclusively with the following three methods.  A\n  call like\n\n     a[1:2] = b\n\n  is translated to\n\n     a[slice(1, 2, None)] = b\n\n  and so forth.  Missing slice items are always filled in with "None".\n\nobject.__getitem__(self, key)\n\n   Called to implement evaluation of "self[key]". For sequence types,\n   the accepted keys should be integers and slice objects.  Note that\n   the special interpretation of negative indexes (if the class wishes\n   to emulate a sequence type) is up to the "__getitem__()" method. If\n   *key* is of an inappropriate type, "TypeError" may be raised; if of\n   a value outside the set of indexes for the sequence (after any\n   special interpretation of negative values), "IndexError" should be\n   raised. For mapping types, if *key* is missing (not in the\n   container), "KeyError" should be raised.\n\n   Note: "for" loops expect that an "IndexError" will be raised for\n     illegal indexes to allow proper detection of the end of the\n     sequence.\n\nobject.__setitem__(self, key, value)\n\n   Called to implement assignment to "self[key]".  Same note as for\n   "__getitem__()".  This should only be implemented for mappings if\n   the objects support changes to the values for keys, or if new keys\n   can be added, or for sequences if elements can be replaced.  The\n   same exceptions should be raised for improper *key* values as for\n   the "__getitem__()" method.\n\nobject.__delitem__(self, key)\n\n   Called to implement deletion of "self[key]".  Same note as for\n   "__getitem__()".  This should only be implemented for mappings if\n   the objects support removal of keys, or for sequences if elements\n   can be removed from the sequence.  The same exceptions should be\n   raised for improper *key* values as for the "__getitem__()" method.\n\nobject.__iter__(self)\n\n   This method is called when an iterator is required for a container.\n   This method should return a new iterator object that can iterate\n   over all the objects in the container.  For mappings, it should\n   iterate over the keys of the container, and should also be made\n   available as the method "keys()".\n\n   Iterator objects also need to implement this method; they are\n   required to return themselves.  For more information on iterator\n   objects, see *Iterator Types*.\n\nobject.__reversed__(self)\n\n   Called (if present) by the "reversed()" built-in to implement\n   reverse iteration.  It should return a new iterator object that\n   iterates over all the objects in the container in reverse order.\n\n   If the "__reversed__()" method is not provided, the "reversed()"\n   built-in will fall back to using the sequence protocol ("__len__()"\n   and "__getitem__()").  Objects that support the sequence protocol\n   should only provide "__reversed__()" if they can provide an\n   implementation that is more efficient than the one provided by\n   "reversed()".\n\nThe membership test operators ("in" and "not in") are normally\nimplemented as an iteration through a sequence.  However, container\nobjects can supply the following special method with a more efficient\nimplementation, which also does not require the object be a sequence.\n\nobject.__contains__(self, item)\n\n   Called to implement membership test operators.  Should return true\n   if *item* is in *self*, false otherwise.  For mapping objects, this\n   should consider the keys of the mapping rather than the values or\n   the key-item pairs.\n\n   For objects that don\'t define "__contains__()", the membership test\n   first tries iteration via "__iter__()", then the old sequence\n   iteration protocol via "__getitem__()", see *this section in the\n   language reference*.\n\n\nEmulating numeric types\n=======================\n\nThe following methods can be defined to emulate numeric objects.\nMethods corresponding to operations that are not supported by the\nparticular kind of number implemented (e.g., bitwise operations for\nnon-integral numbers) should be left undefined.\n\nobject.__add__(self, other)\nobject.__sub__(self, other)\nobject.__mul__(self, other)\nobject.__truediv__(self, other)\nobject.__floordiv__(self, other)\nobject.__mod__(self, other)\nobject.__divmod__(self, other)\nobject.__pow__(self, other[, modulo])\nobject.__lshift__(self, other)\nobject.__rshift__(self, other)\nobject.__and__(self, other)\nobject.__xor__(self, other)\nobject.__or__(self, other)\n\n   These methods are called to implement the binary arithmetic\n   operations ("+", "-", "*", "/", "//", "%", "divmod()", "pow()",\n   "**", "<<", ">>", "&", "^", "|").  For instance, to evaluate the\n   expression "x + y", where *x* is an instance of a class that has an\n   "__add__()" method, "x.__add__(y)" is called.  The "__divmod__()"\n   method should be the equivalent to using "__floordiv__()" and\n   "__mod__()"; it should not be related to "__truediv__()".  Note\n   that "__pow__()" should be defined to accept an optional third\n   argument if the ternary version of the built-in "pow()" function is\n   to be supported.\n\n   If one of those methods does not support the operation with the\n   supplied arguments, it should return "NotImplemented".\n\nobject.__radd__(self, other)\nobject.__rsub__(self, other)\nobject.__rmul__(self, other)\nobject.__rtruediv__(self, other)\nobject.__rfloordiv__(self, other)\nobject.__rmod__(self, other)\nobject.__rdivmod__(self, other)\nobject.__rpow__(self, other)\nobject.__rlshift__(self, other)\nobject.__rrshift__(self, other)\nobject.__rand__(self, other)\nobject.__rxor__(self, other)\nobject.__ror__(self, other)\n\n   These methods are called to implement the binary arithmetic\n   operations ("+", "-", "*", "/", "//", "%", "divmod()", "pow()",\n   "**", "<<", ">>", "&", "^", "|") with reflected (swapped) operands.\n   These functions are only called if the left operand does not\n   support the corresponding operation and the operands are of\n   different types. [2]  For instance, to evaluate the expression "x -\n   y", where *y* is an instance of a class that has an "__rsub__()"\n   method, "y.__rsub__(x)" is called if "x.__sub__(y)" returns\n   *NotImplemented*.\n\n   Note that ternary "pow()" will not try calling "__rpow__()" (the\n   coercion rules would become too complicated).\n\n   Note: If the right operand\'s type is a subclass of the left operand\'s\n     type and that subclass provides the reflected method for the\n     operation, this method will be called before the left operand\'s\n     non-reflected method.  This behavior allows subclasses to\n     override their ancestors\' operations.\n\nobject.__iadd__(self, other)\nobject.__isub__(self, other)\nobject.__imul__(self, other)\nobject.__itruediv__(self, other)\nobject.__ifloordiv__(self, other)\nobject.__imod__(self, other)\nobject.__ipow__(self, other[, modulo])\nobject.__ilshift__(self, other)\nobject.__irshift__(self, other)\nobject.__iand__(self, other)\nobject.__ixor__(self, other)\nobject.__ior__(self, other)\n\n   These methods are called to implement the augmented arithmetic\n   assignments ("+=", "-=", "*=", "/=", "//=", "%=", "**=", "<<=",\n   ">>=", "&=", "^=", "|=").  These methods should attempt to do the\n   operation in-place (modifying *self*) and return the result (which\n   could be, but does not have to be, *self*).  If a specific method\n   is not defined, the augmented assignment falls back to the normal\n   methods.  For instance, if *x* is an instance of a class with an\n   "__iadd__()" method, "x += y" is equivalent to "x = x.__iadd__(y)"\n   . Otherwise, "x.__add__(y)" and "y.__radd__(x)" are considered, as\n   with the evaluation of "x + y". In certain situations, augmented\n   assignment can result in unexpected errors (see *Why does\n   a_tuple[i] += [\'item\'] raise an exception when the addition\n   works?*), but this behavior is in fact part of the data model.\n\nobject.__neg__(self)\nobject.__pos__(self)\nobject.__abs__(self)\nobject.__invert__(self)\n\n   Called to implement the unary arithmetic operations ("-", "+",\n   "abs()" and "~").\n\nobject.__complex__(self)\nobject.__int__(self)\nobject.__float__(self)\nobject.__round__(self[, n])\n\n   Called to implement the built-in functions "complex()", "int()",\n   "float()" and "round()".  Should return a value of the appropriate\n   type.\n\nobject.__index__(self)\n\n   Called to implement "operator.index()", and whenever Python needs\n   to losslessly convert the numeric object to an integer object (such\n   as in slicing, or in the built-in "bin()", "hex()" and "oct()"\n   functions). Presence of this method indicates that the numeric\n   object is an integer type.  Must return an integer.\n\n   Note: When "__index__()" is defined, "__int__()" should also be\n     defined, and both shuld return the same value, in order to have a\n     coherent integer type class.\n\n\nWith Statement Context Managers\n===============================\n\nA *context manager* is an object that defines the runtime context to\nbe established when executing a "with" statement. The context manager\nhandles the entry into, and the exit from, the desired runtime context\nfor the execution of the block of code.  Context managers are normally\ninvoked using the "with" statement (described in section *The with\nstatement*), but can also be used by directly invoking their methods.\n\nTypical uses of context managers include saving and restoring various\nkinds of global state, locking and unlocking resources, closing opened\nfiles, etc.\n\nFor more information on context managers, see *Context Manager Types*.\n\nobject.__enter__(self)\n\n   Enter the runtime context related to this object. The "with"\n   statement will bind this method\'s return value to the target(s)\n   specified in the "as" clause of the statement, if any.\n\nobject.__exit__(self, exc_type, exc_value, traceback)\n\n   Exit the runtime context related to this object. The parameters\n   describe the exception that caused the context to be exited. If the\n   context was exited without an exception, all three arguments will\n   be "None".\n\n   If an exception is supplied, and the method wishes to suppress the\n   exception (i.e., prevent it from being propagated), it should\n   return a true value. Otherwise, the exception will be processed\n   normally upon exit from this method.\n\n   Note that "__exit__()" methods should not reraise the passed-in\n   exception; this is the caller\'s responsibility.\n\nSee also:\n\n   **PEP 0343** - The "with" statement\n      The specification, background, and examples for the Python\n      "with" statement.\n\n\nSpecial method lookup\n=====================\n\nFor custom classes, implicit invocations of special methods are only\nguaranteed to work correctly if defined on an object\'s type, not in\nthe object\'s instance dictionary.  That behaviour is the reason why\nthe following code raises an exception:\n\n   >>> class C:\n   ...     pass\n   ...\n   >>> c = C()\n   >>> c.__len__ = lambda: 5\n   >>> len(c)\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in <module>\n   TypeError: object of type \'C\' has no len()\n\nThe rationale behind this behaviour lies with a number of special\nmethods such as "__hash__()" and "__repr__()" that are implemented by\nall objects, including type objects. If the implicit lookup of these\nmethods used the conventional lookup process, they would fail when\ninvoked on the type object itself:\n\n   >>> 1 .__hash__() == hash(1)\n   True\n   >>> int.__hash__() == hash(int)\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in <module>\n   TypeError: descriptor \'__hash__\' of \'int\' object needs an argument\n\nIncorrectly attempting to invoke an unbound method of a class in this\nway is sometimes referred to as \'metaclass confusion\', and is avoided\nby bypassing the instance when looking up special methods:\n\n   >>> type(1).__hash__(1) == hash(1)\n   True\n   >>> type(int).__hash__(int) == hash(int)\n   True\n\nIn addition to bypassing any instance attributes in the interest of\ncorrectness, implicit special method lookup generally also bypasses\nthe "__getattribute__()" method even of the object\'s metaclass:\n\n   >>> class Meta(type):\n   ...    def __getattribute__(*args):\n   ...       print("Metaclass getattribute invoked")\n   ...       return type.__getattribute__(*args)\n   ...\n   >>> class C(object, metaclass=Meta):\n   ...     def __len__(self):\n   ...         return 10\n   ...     def __getattribute__(*args):\n   ...         print("Class getattribute invoked")\n   ...         return object.__getattribute__(*args)\n   ...\n   >>> c = C()\n   >>> c.__len__()                 # Explicit lookup via instance\n   Class getattribute invoked\n   10\n   >>> type(c).__len__(c)          # Explicit lookup via type\n   Metaclass getattribute invoked\n   10\n   >>> len(c)                      # Implicit lookup\n   10\n\nBypassing the "__getattribute__()" machinery in this fashion provides\nsignificant scope for speed optimisations within the interpreter, at\nthe cost of some flexibility in the handling of special methods (the\nspecial method *must* be set on the class object itself in order to be\nconsistently invoked by the interpreter).\n\n-[ Footnotes ]-\n\n[1] It *is* possible in some cases to change an object\'s type, under\n    certain controlled conditions. It generally isn\'t a good idea\n    though, since it can lead to some very strange behaviour if it is\n    handled incorrectly.\n\n[2] For operands of the same type, it is assumed that if the non-\n    reflected method (such as "__add__()") fails the operation is not\n    supported, which is why the reflected method is not called.\n',
+ 'string-methods': '\nString Methods\n**************\n\nStrings implement all of the *common* sequence operations, along with\nthe additional methods described below.\n\nStrings also support two styles of string formatting, one providing a\nlarge degree of flexibility and customization (see "str.format()",\n*Format String Syntax* and *String Formatting*) and the other based on\nC "printf" style formatting that handles a narrower range of types and\nis slightly harder to use correctly, but is often faster for the cases\nit can handle (*printf-style String Formatting*).\n\nThe *Text Processing Services* section of the standard library covers\na number of other modules that provide various text related utilities\n(including regular expression support in the "re" module).\n\nstr.capitalize()\n\n   Return a copy of the string with its first character capitalized\n   and the rest lowercased.\n\nstr.casefold()\n\n   Return a casefolded copy of the string. Casefolded strings may be\n   used for caseless matching.\n\n   Casefolding is similar to lowercasing but more aggressive because\n   it is intended to remove all case distinctions in a string. For\n   example, the German lowercase letter "\'\xc3\x9f\'" is equivalent to ""ss"".\n   Since it is already lowercase, "lower()" would do nothing to "\'\xc3\x9f\'";\n   "casefold()" converts it to ""ss"".\n\n   The casefolding algorithm is described in section 3.13 of the\n   Unicode Standard.\n\n   New in version 3.3.\n\nstr.center(width[, fillchar])\n\n   Return centered in a string of length *width*. Padding is done\n   using the specified *fillchar* (default is a space).\n\nstr.count(sub[, start[, end]])\n\n   Return the number of non-overlapping occurrences of substring *sub*\n   in the range [*start*, *end*].  Optional arguments *start* and\n   *end* are interpreted as in slice notation.\n\nstr.encode(encoding="utf-8", errors="strict")\n\n   Return an encoded version of the string as a bytes object. Default\n   encoding is "\'utf-8\'". *errors* may be given to set a different\n   error handling scheme. The default for *errors* is "\'strict\'",\n   meaning that encoding errors raise a "UnicodeError". Other possible\n   values are "\'ignore\'", "\'replace\'", "\'xmlcharrefreplace\'",\n   "\'backslashreplace\'" and any other name registered via\n   "codecs.register_error()", see section *Codec Base Classes*. For a\n   list of possible encodings, see section *Standard Encodings*.\n\n   Changed in version 3.1: Support for keyword arguments added.\n\nstr.endswith(suffix[, start[, end]])\n\n   Return "True" if the string ends with the specified *suffix*,\n   otherwise return "False".  *suffix* can also be a tuple of suffixes\n   to look for.  With optional *start*, test beginning at that\n   position.  With optional *end*, stop comparing at that position.\n\nstr.expandtabs(tabsize=8)\n\n   Return a copy of the string where all tab characters are replaced\n   by one or more spaces, depending on the current column and the\n   given tab size.  Tab positions occur every *tabsize* characters\n   (default is 8, giving tab positions at columns 0, 8, 16 and so on).\n   To expand the string, the current column is set to zero and the\n   string is examined character by character.  If the character is a\n   tab ("\\t"), one or more space characters are inserted in the result\n   until the current column is equal to the next tab position. (The\n   tab character itself is not copied.)  If the character is a newline\n   ("\\n") or return ("\\r"), it is copied and the current column is\n   reset to zero.  Any other character is copied unchanged and the\n   current column is incremented by one regardless of how the\n   character is represented when printed.\n\n   >>> \'01\\t012\\t0123\\t01234\'.expandtabs()\n   \'01      012     0123    01234\'\n   >>> \'01\\t012\\t0123\\t01234\'.expandtabs(4)\n   \'01  012 0123    01234\'\n\nstr.find(sub[, start[, end]])\n\n   Return the lowest index in the string where substring *sub* is\n   found, such that *sub* is contained in the slice "s[start:end]".\n   Optional arguments *start* and *end* are interpreted as in slice\n   notation.  Return "-1" if *sub* is not found.\n\n   Note: The "find()" method should be used only if you need to know the\n     position of *sub*.  To check if *sub* is a substring or not, use\n     the "in" operator:\n\n        >>> \'Py\' in \'Python\'\n        True\n\nstr.format(*args, **kwargs)\n\n   Perform a string formatting operation.  The string on which this\n   method is called can contain literal text or replacement fields\n   delimited by braces "{}".  Each replacement field contains either\n   the numeric index of a positional argument, or the name of a\n   keyword argument.  Returns a copy of the string where each\n   replacement field is replaced with the string value of the\n   corresponding argument.\n\n   >>> "The sum of 1 + 2 is {0}".format(1+2)\n   \'The sum of 1 + 2 is 3\'\n\n   See *Format String Syntax* for a description of the various\n   formatting options that can be specified in format strings.\n\nstr.format_map(mapping)\n\n   Similar to "str.format(**mapping)", except that "mapping" is used\n   directly and not copied to a "dict".  This is useful if for example\n   "mapping" is a dict subclass:\n\n   >>> class Default(dict):\n   ...     def __missing__(self, key):\n   ...         return key\n   ...\n   >>> \'{name} was born in {country}\'.format_map(Default(name=\'Guido\'))\n   \'Guido was born in country\'\n\n   New in version 3.2.\n\nstr.index(sub[, start[, end]])\n\n   Like "find()", but raise "ValueError" when the substring is not\n   found.\n\nstr.isalnum()\n\n   Return true if all characters in the string are alphanumeric and\n   there is at least one character, false otherwise.  A character "c"\n   is alphanumeric if one of the following returns "True":\n   "c.isalpha()", "c.isdecimal()", "c.isdigit()", or "c.isnumeric()".\n\nstr.isalpha()\n\n   Return true if all characters in the string are alphabetic and\n   there is at least one character, false otherwise.  Alphabetic\n   characters are those characters defined in the Unicode character\n   database as "Letter", i.e., those with general category property\n   being one of "Lm", "Lt", "Lu", "Ll", or "Lo".  Note that this is\n   different from the "Alphabetic" property defined in the Unicode\n   Standard.\n\nstr.isdecimal()\n\n   Return true if all characters in the string are decimal characters\n   and there is at least one character, false otherwise. Decimal\n   characters are those from general category "Nd". This category\n   includes digit characters, and all characters that can be used to\n   form decimal-radix numbers, e.g. U+0660, ARABIC-INDIC DIGIT ZERO.\n\nstr.isdigit()\n\n   Return true if all characters in the string are digits and there is\n   at least one character, false otherwise.  Digits include decimal\n   characters and digits that need special handling, such as the\n   compatibility superscript digits.  Formally, a digit is a character\n   that has the property value Numeric_Type=Digit or\n   Numeric_Type=Decimal.\n\nstr.isidentifier()\n\n   Return true if the string is a valid identifier according to the\n   language definition, section *Identifiers and keywords*.\n\n   Use "keyword.iskeyword()" to test for reserved identifiers such as\n   "def" and "class".\n\nstr.islower()\n\n   Return true if all cased characters [4] in the string are lowercase\n   and there is at least one cased character, false otherwise.\n\nstr.isnumeric()\n\n   Return true if all characters in the string are numeric characters,\n   and there is at least one character, false otherwise. Numeric\n   characters include digit characters, and all characters that have\n   the Unicode numeric value property, e.g. U+2155, VULGAR FRACTION\n   ONE FIFTH.  Formally, numeric characters are those with the\n   property value Numeric_Type=Digit, Numeric_Type=Decimal or\n   Numeric_Type=Numeric.\n\nstr.isprintable()\n\n   Return true if all characters in the string are printable or the\n   string is empty, false otherwise.  Nonprintable characters are\n   those characters defined in the Unicode character database as\n   "Other" or "Separator", excepting the ASCII space (0x20) which is\n   considered printable.  (Note that printable characters in this\n   context are those which should not be escaped when "repr()" is\n   invoked on a string.  It has no bearing on the handling of strings\n   written to "sys.stdout" or "sys.stderr".)\n\nstr.isspace()\n\n   Return true if there are only whitespace characters in the string\n   and there is at least one character, false otherwise.  Whitespace\n   characters  are those characters defined in the Unicode character\n   database as "Other" or "Separator" and those with bidirectional\n   property being one of "WS", "B", or "S".\n\nstr.istitle()\n\n   Return true if the string is a titlecased string and there is at\n   least one character, for example uppercase characters may only\n   follow uncased characters and lowercase characters only cased ones.\n   Return false otherwise.\n\nstr.isupper()\n\n   Return true if all cased characters [4] in the string are uppercase\n   and there is at least one cased character, false otherwise.\n\nstr.join(iterable)\n\n   Return a string which is the concatenation of the strings in the\n   *iterable* *iterable*.  A "TypeError" will be raised if there are\n   any non-string values in *iterable*, including "bytes" objects.\n   The separator between elements is the string providing this method.\n\nstr.ljust(width[, fillchar])\n\n   Return the string left justified in a string of length *width*.\n   Padding is done using the specified *fillchar* (default is a\n   space).  The original string is returned if *width* is less than or\n   equal to "len(s)".\n\nstr.lower()\n\n   Return a copy of the string with all the cased characters [4]\n   converted to lowercase.\n\n   The lowercasing algorithm used is described in section 3.13 of the\n   Unicode Standard.\n\nstr.lstrip([chars])\n\n   Return a copy of the string with leading characters removed.  The\n   *chars* argument is a string specifying the set of characters to be\n   removed.  If omitted or "None", the *chars* argument defaults to\n   removing whitespace.  The *chars* argument is not a prefix; rather,\n   all combinations of its values are stripped:\n\n   >>> \'   spacious   \'.lstrip()\n   \'spacious   \'\n   >>> \'www.example.com\'.lstrip(\'cmowz.\')\n   \'example.com\'\n\nstatic str.maketrans(x[, y[, z]])\n\n   This static method returns a translation table usable for\n   "str.translate()".\n\n   If there is only one argument, it must be a dictionary mapping\n   Unicode ordinals (integers) or characters (strings of length 1) to\n   Unicode ordinals, strings (of arbitrary lengths) or None.\n   Character keys will then be converted to ordinals.\n\n   If there are two arguments, they must be strings of equal length,\n   and in the resulting dictionary, each character in x will be mapped\n   to the character at the same position in y.  If there is a third\n   argument, it must be a string, whose characters will be mapped to\n   None in the result.\n\nstr.partition(sep)\n\n   Split the string at the first occurrence of *sep*, and return a\n   3-tuple containing the part before the separator, the separator\n   itself, and the part after the separator.  If the separator is not\n   found, return a 3-tuple containing the string itself, followed by\n   two empty strings.\n\nstr.replace(old, new[, count])\n\n   Return a copy of the string with all occurrences of substring *old*\n   replaced by *new*.  If the optional argument *count* is given, only\n   the first *count* occurrences are replaced.\n\nstr.rfind(sub[, start[, end]])\n\n   Return the highest index in the string where substring *sub* is\n   found, such that *sub* is contained within "s[start:end]".\n   Optional arguments *start* and *end* are interpreted as in slice\n   notation.  Return "-1" on failure.\n\nstr.rindex(sub[, start[, end]])\n\n   Like "rfind()" but raises "ValueError" when the substring *sub* is\n   not found.\n\nstr.rjust(width[, fillchar])\n\n   Return the string right justified in a string of length *width*.\n   Padding is done using the specified *fillchar* (default is a\n   space). The original string is returned if *width* is less than or\n   equal to "len(s)".\n\nstr.rpartition(sep)\n\n   Split the string at the last occurrence of *sep*, and return a\n   3-tuple containing the part before the separator, the separator\n   itself, and the part after the separator.  If the separator is not\n   found, return a 3-tuple containing two empty strings, followed by\n   the string itself.\n\nstr.rsplit(sep=None, maxsplit=-1)\n\n   Return a list of the words in the string, using *sep* as the\n   delimiter string. If *maxsplit* is given, at most *maxsplit* splits\n   are done, the *rightmost* ones.  If *sep* is not specified or\n   "None", any whitespace string is a separator.  Except for splitting\n   from the right, "rsplit()" behaves like "split()" which is\n   described in detail below.\n\nstr.rstrip([chars])\n\n   Return a copy of the string with trailing characters removed.  The\n   *chars* argument is a string specifying the set of characters to be\n   removed.  If omitted or "None", the *chars* argument defaults to\n   removing whitespace.  The *chars* argument is not a suffix; rather,\n   all combinations of its values are stripped:\n\n   >>> \'   spacious   \'.rstrip()\n   \'   spacious\'\n   >>> \'mississippi\'.rstrip(\'ipz\')\n   \'mississ\'\n\nstr.split(sep=None, maxsplit=-1)\n\n   Return a list of the words in the string, using *sep* as the\n   delimiter string.  If *maxsplit* is given, at most *maxsplit*\n   splits are done (thus, the list will have at most "maxsplit+1"\n   elements).  If *maxsplit* is not specified or "-1", then there is\n   no limit on the number of splits (all possible splits are made).\n\n   If *sep* is given, consecutive delimiters are not grouped together\n   and are deemed to delimit empty strings (for example,\n   "\'1,,2\'.split(\',\')" returns "[\'1\', \'\', \'2\']").  The *sep* argument\n   may consist of multiple characters (for example,\n   "\'1<>2<>3\'.split(\'<>\')" returns "[\'1\', \'2\', \'3\']"). Splitting an\n   empty string with a specified separator returns "[\'\']".\n\n   If *sep* is not specified or is "None", a different splitting\n   algorithm is applied: runs of consecutive whitespace are regarded\n   as a single separator, and the result will contain no empty strings\n   at the start or end if the string has leading or trailing\n   whitespace.  Consequently, splitting an empty string or a string\n   consisting of just whitespace with a "None" separator returns "[]".\n\n   For example, "\' 1  2   3  \'.split()" returns "[\'1\', \'2\', \'3\']", and\n   "\'  1  2   3  \'.split(None, 1)" returns "[\'1\', \'2   3  \']".\n\nstr.splitlines([keepends])\n\n   Return a list of the lines in the string, breaking at line\n   boundaries. This method uses the *universal newlines* approach to\n   splitting lines. Line breaks are not included in the resulting list\n   unless *keepends* is given and true.\n\n   For example, "\'ab c\\n\\nde fg\\rkl\\r\\n\'.splitlines()" returns "[\'ab\n   c\', \'\', \'de fg\', \'kl\']", while the same call with\n   "splitlines(True)" returns "[\'ab c\\n\', \'\\n\', \'de fg\\r\', \'kl\\r\\n\']".\n\n   Unlike "split()" when a delimiter string *sep* is given, this\n   method returns an empty list for the empty string, and a terminal\n   line break does not result in an extra line.\n\nstr.startswith(prefix[, start[, end]])\n\n   Return "True" if string starts with the *prefix*, otherwise return\n   "False". *prefix* can also be a tuple of prefixes to look for.\n   With optional *start*, test string beginning at that position.\n   With optional *end*, stop comparing string at that position.\n\nstr.strip([chars])\n\n   Return a copy of the string with the leading and trailing\n   characters removed. The *chars* argument is a string specifying the\n   set of characters to be removed. If omitted or "None", the *chars*\n   argument defaults to removing whitespace. The *chars* argument is\n   not a prefix or suffix; rather, all combinations of its values are\n   stripped:\n\n   >>> \'   spacious   \'.strip()\n   \'spacious\'\n   >>> \'www.example.com\'.strip(\'cmowz.\')\n   \'example\'\n\nstr.swapcase()\n\n   Return a copy of the string with uppercase characters converted to\n   lowercase and vice versa. Note that it is not necessarily true that\n   "s.swapcase().swapcase() == s".\n\nstr.title()\n\n   Return a titlecased version of the string where words start with an\n   uppercase character and the remaining characters are lowercase.\n\n   The algorithm uses a simple language-independent definition of a\n   word as groups of consecutive letters.  The definition works in\n   many contexts but it means that apostrophes in contractions and\n   possessives form word boundaries, which may not be the desired\n   result:\n\n      >>> "they\'re bill\'s friends from the UK".title()\n      "They\'Re Bill\'S Friends From The Uk"\n\n   A workaround for apostrophes can be constructed using regular\n   expressions:\n\n      >>> import re\n      >>> def titlecase(s):\n      ...     return re.sub(r"[A-Za-z]+(\'[A-Za-z]+)?",\n      ...                   lambda mo: mo.group(0)[0].upper() +\n      ...                              mo.group(0)[1:].lower(),\n      ...                   s)\n      ...\n      >>> titlecase("they\'re bill\'s friends.")\n      "They\'re Bill\'s Friends."\n\nstr.translate(map)\n\n   Return a copy of the *s* where all characters have been mapped\n   through the *map* which must be a dictionary of Unicode ordinals\n   (integers) to Unicode ordinals, strings or "None".  Unmapped\n   characters are left untouched. Characters mapped to "None" are\n   deleted.\n\n   You can use "str.maketrans()" to create a translation map from\n   character-to-character mappings in different formats.\n\n   Note: An even more flexible approach is to create a custom character\n     mapping codec using the "codecs" module (see "encodings.cp1251"\n     for an example).\n\nstr.upper()\n\n   Return a copy of the string with all the cased characters [4]\n   converted to uppercase.  Note that "str.upper().isupper()" might be\n   "False" if "s" contains uncased characters or if the Unicode\n   category of the resulting character(s) is not "Lu" (Letter,\n   uppercase), but e.g. "Lt" (Letter, titlecase).\n\n   The uppercasing algorithm used is described in section 3.13 of the\n   Unicode Standard.\n\nstr.zfill(width)\n\n   Return the numeric string left filled with zeros in a string of\n   length *width*.  A sign prefix is handled correctly.  The original\n   string is returned if *width* is less than or equal to "len(s)".\n',
+ 'strings': '\nString and Bytes literals\n*************************\n\nString literals are described by the following lexical definitions:\n\n   stringliteral   ::= [stringprefix](shortstring | longstring)\n   stringprefix    ::= "r" | "u" | "R" | "U"\n   shortstring     ::= "\'" shortstringitem* "\'" | \'"\' shortstringitem* \'"\'\n   longstring      ::= "\'\'\'" longstringitem* "\'\'\'" | \'"""\' longstringitem* \'"""\'\n   shortstringitem ::= shortstringchar | stringescapeseq\n   longstringitem  ::= longstringchar | stringescapeseq\n   shortstringchar ::= <any source character except "\\" or newline or the quote>\n   longstringchar  ::= <any source character except "\\">\n   stringescapeseq ::= "\\" <any source character>\n\n   bytesliteral   ::= bytesprefix(shortbytes | longbytes)\n   bytesprefix    ::= "b" | "B" | "br" | "Br" | "bR" | "BR" | "rb" | "rB" | "Rb" | "RB"\n   shortbytes     ::= "\'" shortbytesitem* "\'" | \'"\' shortbytesitem* \'"\'\n   longbytes      ::= "\'\'\'" longbytesitem* "\'\'\'" | \'"""\' longbytesitem* \'"""\'\n   shortbytesitem ::= shortbyteschar | bytesescapeseq\n   longbytesitem  ::= longbyteschar | bytesescapeseq\n   shortbyteschar ::= <any ASCII character except "\\" or newline or the quote>\n   longbyteschar  ::= <any ASCII character except "\\">\n   bytesescapeseq ::= "\\" <any ASCII character>\n\nOne syntactic restriction not indicated by these productions is that\nwhitespace is not allowed between the "stringprefix" or "bytesprefix"\nand the rest of the literal. The source character set is defined by\nthe encoding declaration; it is UTF-8 if no encoding declaration is\ngiven in the source file; see section *Encoding declarations*.\n\nIn plain English: Both types of literals can be enclosed in matching\nsingle quotes ("\'") or double quotes (""").  They can also be enclosed\nin matching groups of three single or double quotes (these are\ngenerally referred to as *triple-quoted strings*).  The backslash\n("\\") character is used to escape characters that otherwise have a\nspecial meaning, such as newline, backslash itself, or the quote\ncharacter.\n\nBytes literals are always prefixed with "\'b\'" or "\'B\'"; they produce\nan instance of the "bytes" type instead of the "str" type.  They may\nonly contain ASCII characters; bytes with a numeric value of 128 or\ngreater must be expressed with escapes.\n\nAs of Python 3.3 it is possible again to prefix unicode strings with a\n"u" prefix to simplify maintenance of dual 2.x and 3.x codebases.\n\nBoth string and bytes literals may optionally be prefixed with a\nletter "\'r\'" or "\'R\'"; such strings are called *raw strings* and treat\nbackslashes as literal characters.  As a result, in string literals,\n"\'\\U\'" and "\'\\u\'" escapes in raw strings are not treated specially.\nGiven that Python 2.x\'s raw unicode literals behave differently than\nPython 3.x\'s the "\'ur\'" syntax is not supported.\n\n   New in version 3.3: The "\'rb\'" prefix of raw bytes literals has\n   been added as a synonym of "\'br\'".\n\n   New in version 3.3: Support for the unicode legacy literal\n   ("u\'value\'") was reintroduced to simplify the maintenance of dual\n   Python 2.x and 3.x codebases. See **PEP 414** for more information.\n\nIn triple-quoted strings, unescaped newlines and quotes are allowed\n(and are retained), except that three unescaped quotes in a row\nterminate the string.  (A "quote" is the character used to open the\nstring, i.e. either "\'" or """.)\n\nUnless an "\'r\'" or "\'R\'" prefix is present, escape sequences in\nstrings are interpreted according to rules similar to those used by\nStandard C.  The recognized escape sequences are:\n\n+-------------------+-----------------------------------+---------+\n| Escape Sequence   | Meaning                           | Notes   |\n+===================+===================================+=========+\n+-------------------+-----------------------------------+---------+\n+-------------------+-----------------------------------+---------+\n+-------------------+-----------------------------------+---------+\n+-------------------+-----------------------------------+---------+\n+-------------------+-----------------------------------+---------+\n+-------------------+-----------------------------------+---------+\n+-------------------+-----------------------------------+---------+\n+-------------------+-----------------------------------+---------+\n+-------------------+-----------------------------------+---------+\n+-------------------+-----------------------------------+---------+\n+-------------------+-----------------------------------+---------+\n| "\\ooo"            | Character with octal value *ooo*  | (1,3)   |\n+-------------------+-----------------------------------+---------+\n| "\\xhh"            | Character with hex value *hh*     | (2,3)   |\n+-------------------+-----------------------------------+---------+\n\nEscape sequences only recognized in string literals are:\n\n+-------------------+-----------------------------------+---------+\n| Escape Sequence   | Meaning                           | Notes   |\n+===================+===================================+=========+\n| "\\N{name}"        | Character named *name* in the     | (4)     |\n+-------------------+-----------------------------------+---------+\n| "\\uxxxx"          | Character with 16-bit hex value   | (5)     |\n+-------------------+-----------------------------------+---------+\n| "\\Uxxxxxxxx"      | Character with 32-bit hex value   | (6)     |\n+-------------------+-----------------------------------+---------+\n\nNotes:\n\n1. As in Standard C, up to three octal digits are accepted.\n\n2. Unlike in Standard C, exactly two hex digits are required.\n\n3. In a bytes literal, hexadecimal and octal escapes denote the byte\n   with the given value. In a string literal, these escapes denote a\n   Unicode character with the given value.\n\n4. Changed in version 3.3: Support for name aliases [1] has been\n   added.\n\n5. Individual code units which form parts of a surrogate pair can be\n   encoded using this escape sequence.  Exactly four hex digits are\n   required.\n\n6. Any Unicode character can be encoded this way.  Exactly eight hex\n   digits are required.\n\nUnlike Standard C, all unrecognized escape sequences are left in the\nstring unchanged, i.e., *the backslash is left in the string*.  (This\nbehavior is useful when debugging: if an escape sequence is mistyped,\nthe resulting output is more easily recognized as broken.)  It is also\nimportant to note that the escape sequences only recognized in string\nliterals fall into the category of unrecognized escapes for bytes\nliterals.\n\nEven in a raw string, string quotes can be escaped with a backslash,\nbut the backslash remains in the string; for example, "r"\\""" is a\nvalid string literal consisting of two characters: a backslash and a\ndouble quote; "r"\\"" is not a valid string literal (even a raw string\ncannot end in an odd number of backslashes).  Specifically, *a raw\nstring cannot end in a single backslash* (since the backslash would\nescape the following quote character).  Note also that a single\nbackslash followed by a newline is interpreted as those two characters\nas part of the string, *not* as a line continuation.\n',
+ 'subscriptions': '\nSubscriptions\n*************\n\nA subscription selects an item of a sequence (string, tuple or list)\nor mapping (dictionary) object:\n\n   subscription ::= primary "[" expression_list "]"\n\nThe primary must evaluate to an object that supports subscription,\ne.g. a list or dictionary.  User-defined objects can support\nsubscription by defining a "__getitem__()" method.\n\nFor built-in objects, there are two types of objects that support\nsubscription:\n\nIf the primary is a mapping, the expression list must evaluate to an\nobject whose value is one of the keys of the mapping, and the\nsubscription selects the value in the mapping that corresponds to that\nkey.  (The expression list is a tuple except if it has exactly one\nitem.)\n\nIf the primary is a sequence, the expression (list) must evaluate to\nan integer or a slice (as discussed in the following section).\n\nThe formal syntax makes no special provision for negative indices in\nsequences; however, built-in sequences all provide a "__getitem__()"\nmethod that interprets negative indices by adding the length of the\nsequence to the index (so that "x[-1]" selects the last item of "x").\nThe resulting value must be a nonnegative integer less than the number\nof items in the sequence, and the subscription selects the item whose\nindex is that value (counting from zero). Since the support for\nnegative indices and slicing occurs in the object\'s "__getitem__()"\nmethod, subclasses overriding this method will need to explicitly add\nthat support.\n\nA string\'s items are characters.  A character is not a separate data\ntype but a string of exactly one character.\n',
+ 'truth': '\nTruth Value Testing\n*******************\n\nAny object can be tested for truth value, for use in an "if" or\n"while" condition or as operand of the Boolean operations below. The\nfollowing values are considered false:\n\n* "None"\n\n* "False"\n\n* zero of any numeric type, for example, "0", "0.0", "0j".\n\n* any empty sequence, for example, "\'\'", "()", "[]".\n\n* any empty mapping, for example, "{}".\n\n* instances of user-defined classes, if the class defines a\n  "__bool__()" or "__len__()" method, when that method returns the\n  integer zero or "bool" value "False". [1]\n\nAll other values are considered true --- so objects of many types are\nalways true.\n\nOperations and built-in functions that have a Boolean result always\nreturn "0" or "False" for false and "1" or "True" for true, unless\notherwise stated. (Important exception: the Boolean operations "or"\nand "and" always return one of their operands.)\n',
+ 'try': '\nThe "try" statement\n*******************\n\nThe "try" statement specifies exception handlers and/or cleanup code\nfor a group of statements:\n\n   try_stmt  ::= try1_stmt | try2_stmt\n   try1_stmt ::= "try" ":" suite\n                 ("except" [expression ["as" target]] ":" suite)+\n                 ["else" ":" suite]\n                 ["finally" ":" suite]\n   try2_stmt ::= "try" ":" suite\n                 "finally" ":" suite\n\nThe "except" clause(s) specify one or more exception handlers. When no\nexception occurs in the "try" clause, no exception handler is\nexecuted. When an exception occurs in the "try" suite, a search for an\nexception handler is started.  This search inspects the except clauses\nin turn until one is found that matches the exception.  An expression-\nless except clause, if present, must be last; it matches any\nexception.  For an except clause with an expression, that expression\nis evaluated, and the clause matches the exception if the resulting\nobject is "compatible" with the exception.  An object is compatible\nwith an exception if it is the class or a base class of the exception\nobject or a tuple containing an item compatible with the exception.\n\nIf no except clause matches the exception, the search for an exception\nhandler continues in the surrounding code and on the invocation stack.\n[1]\n\nIf the evaluation of an expression in the header of an except clause\nraises an exception, the original search for a handler is canceled and\na search starts for the new exception in the surrounding code and on\nthe call stack (it is treated as if the entire "try" statement raised\nthe exception).\n\nWhen a matching except clause is found, the exception is assigned to\nthe target specified after the "as" keyword in that except clause, if\npresent, and the except clause\'s suite is executed.  All except\nclauses must have an executable block.  When the end of this block is\nreached, execution continues normally after the entire try statement.\n(This means that if two nested handlers exist for the same exception,\nand the exception occurs in the try clause of the inner handler, the\nouter handler will not handle the exception.)\n\nWhen an exception has been assigned using "as target", it is cleared\nat the end of the except clause.  This is as if\n\n   except E as N:\n       foo\n\nwas translated to\n\n   except E as N:\n       try:\n           foo\n       finally:\n           del N\n\nThis means the exception must be assigned to a different name to be\nable to refer to it after the except clause.  Exceptions are cleared\nbecause with the traceback attached to them, they form a reference\ncycle with the stack frame, keeping all locals in that frame alive\nuntil the next garbage collection occurs.\n\nBefore an except clause\'s suite is executed, details about the\nexception are stored in the "sys" module and can be access via\n"sys.exc_info()". "sys.exc_info()" returns a 3-tuple consisting of the\nexception class, the exception instance and a traceback object (see\nsection *The standard type hierarchy*) identifying the point in the\nprogram where the exception occurred.  "sys.exc_info()" values are\nrestored to their previous values (before the call) when returning\nfrom a function that handled an exception.\n\nThe optional "else" clause is executed if and when control flows off\nthe end of the "try" clause. [2] Exceptions in the "else" clause are\nnot handled by the preceding "except" clauses.\n\nIf "finally" is present, it specifies a \'cleanup\' handler.  The "try"\nclause is executed, including any "except" and "else" clauses.  If an\nexception occurs in any of the clauses and is not handled, the\nexception is temporarily saved. The "finally" clause is executed.  If\nthere is a saved exception it is re-raised at the end of the "finally"\nclause.  If the "finally" clause raises another exception, the saved\nexception is set as the context of the new exception. If the "finally"\nclause executes a "return" or "break" statement, the saved exception\nis discarded:\n\n   >>> def f():\n   ...     try:\n   ...         1/0\n   ...     finally:\n   ...         return 42\n   ...\n   >>> f()\n   42\n\nThe exception information is not available to the program during\nexecution of the "finally" clause.\n\nWhen a "return", "break" or "continue" statement is executed in the\n"try" suite of a "try"..."finally" statement, the "finally" clause is\nalso executed \'on the way out.\' A "continue" statement is illegal in\nthe "finally" clause. (The reason is a problem with the current\nimplementation --- this restriction may be lifted in the future).\n\nThe return value of a function is determined by the last "return"\nstatement executed.  Since the "finally" clause always executes, a\n"return" statement executed in the "finally" clause will always be the\nlast one executed:\n\n   >>> def foo():\n   ...     try:\n   ...         return \'try\'\n   ...     finally:\n   ...         return \'finally\'\n   ...\n   >>> foo()\n   \'finally\'\n\nAdditional information on exceptions can be found in section\n*Exceptions*, and information on using the "raise" statement to\ngenerate exceptions may be found in section *The raise statement*.\n',
+ 'types': '\nThe standard type hierarchy\n***************************\n\nBelow is a list of the types that are built into Python.  Extension\nmodules (written in C, Java, or other languages, depending on the\nimplementation) can define additional types.  Future versions of\nPython may add types to the type hierarchy (e.g., rational numbers,\nefficiently stored arrays of integers, etc.), although such additions\nwill often be provided via the standard library instead.\n\nSome of the type descriptions below contain a paragraph listing\n\'special attributes.\'  These are attributes that provide access to the\nimplementation and are not intended for general use.  Their definition\nmay change in the future.\n\nNone\n   This type has a single value.  There is a single object with this\n   value. This object is accessed through the built-in name "None". It\n   is used to signify the absence of a value in many situations, e.g.,\n   it is returned from functions that don\'t explicitly return\n   anything. Its truth value is false.\n\nNotImplemented\n   This type has a single value.  There is a single object with this\n   value. This object is accessed through the built-in name\n   "NotImplemented". Numeric methods and rich comparison methods may\n   return this value if they do not implement the operation for the\n   operands provided.  (The interpreter will then try the reflected\n   operation, or some other fallback, depending on the operator.)  Its\n   truth value is true.\n\nEllipsis\n   This type has a single value.  There is a single object with this\n   value. This object is accessed through the literal "..." or the\n   built-in name "Ellipsis".  Its truth value is true.\n\n"numbers.Number"\n   These are created by numeric literals and returned as results by\n   arithmetic operators and arithmetic built-in functions.  Numeric\n   objects are immutable; once created their value never changes.\n   Python numbers are of course strongly related to mathematical\n   numbers, but subject to the limitations of numerical representation\n   in computers.\n\n   Python distinguishes between integers, floating point numbers, and\n   complex numbers:\n\n   "numbers.Integral"\n      These represent elements from the mathematical set of integers\n      (positive and negative).\n\n      There are two types of integers:\n\n      Integers ("int")\n\n         These represent numbers in an unlimited range, subject to\n         available (virtual) memory only.  For the purpose of shift\n         and mask operations, a binary representation is assumed, and\n         negative numbers are represented in a variant of 2\'s\n         complement which gives the illusion of an infinite string of\n         sign bits extending to the left.\n\n      Booleans ("bool")\n         These represent the truth values False and True.  The two\n         objects representing the values "False" and "True" are the\n         only Boolean objects. The Boolean type is a subtype of the\n         integer type, and Boolean values behave like the values 0 and\n         1, respectively, in almost all contexts, the exception being\n         that when converted to a string, the strings ""False"" or\n         ""True"" are returned, respectively.\n\n      The rules for integer representation are intended to give the\n      most meaningful interpretation of shift and mask operations\n      involving negative integers.\n\n   "numbers.Real" ("float")\n      These represent machine-level double precision floating point\n      numbers. You are at the mercy of the underlying machine\n      architecture (and C or Java implementation) for the accepted\n      range and handling of overflow. Python does not support single-\n      precision floating point numbers; the savings in processor and\n      memory usage that are usually the reason for using these is\n      dwarfed by the overhead of using objects in Python, so there is\n      no reason to complicate the language with two kinds of floating\n      point numbers.\n\n   "numbers.Complex" ("complex")\n      These represent complex numbers as a pair of machine-level\n      double precision floating point numbers.  The same caveats apply\n      as for floating point numbers. The real and imaginary parts of a\n      complex number "z" can be retrieved through the read-only\n      attributes "z.real" and "z.imag".\n\nSequences\n   These represent finite ordered sets indexed by non-negative\n   numbers. The built-in function "len()" returns the number of items\n   of a sequence. When the length of a sequence is *n*, the index set\n   contains the numbers 0, 1, ..., *n*-1.  Item *i* of sequence *a* is\n   selected by "a[i]".\n\n   Sequences also support slicing: "a[i:j]" selects all items with\n   index *k* such that *i* "<=" *k* "<" *j*.  When used as an\n   expression, a slice is a sequence of the same type.  This implies\n   that the index set is renumbered so that it starts at 0.\n\n   Some sequences also support "extended slicing" with a third "step"\n   parameter: "a[i:j:k]" selects all items of *a* with index *x* where\n   "x = i + n*k", *n* ">=" "0" and *i* "<=" *x* "<" *j*.\n\n   Sequences are distinguished according to their mutability:\n\n   Immutable sequences\n      An object of an immutable sequence type cannot change once it is\n      created.  (If the object contains references to other objects,\n      these other objects may be mutable and may be changed; however,\n      the collection of objects directly referenced by an immutable\n      object cannot change.)\n\n      The following types are immutable sequences:\n\n      Strings\n         A string is a sequence of values that represent Unicode\n         codepoints. All the codepoints in range "U+0000 - U+10FFFF"\n         can be represented in a string.  Python doesn\'t have a "chr"\n         type, and every character in the string is represented as a\n         string object with length "1".  The built-in function "ord()"\n         converts a character to its codepoint (as an integer);\n         "chr()" converts an integer in range "0 - 10FFFF" to the\n         corresponding character. "str.encode()" can be used to\n         convert a "str" to "bytes" using the given encoding, and\n         "bytes.decode()" can be used to achieve the opposite.\n\n      Tuples\n         The items of a tuple are arbitrary Python objects. Tuples of\n         two or more items are formed by comma-separated lists of\n         expressions.  A tuple of one item (a \'singleton\') can be\n         formed by affixing a comma to an expression (an expression by\n         itself does not create a tuple, since parentheses must be\n         usable for grouping of expressions).  An empty tuple can be\n         formed by an empty pair of parentheses.\n\n      Bytes\n         A bytes object is an immutable array.  The items are 8-bit\n         bytes, represented by integers in the range 0 <= x < 256.\n         Bytes literals (like "b\'abc\'") and the built-in function\n         "bytes()" can be used to construct bytes objects.  Also,\n         bytes objects can be decoded to strings via the "decode()"\n         method.\n\n   Mutable sequences\n      Mutable sequences can be changed after they are created.  The\n      subscription and slicing notations can be used as the target of\n      assignment and "del" (delete) statements.\n\n      There are currently two intrinsic mutable sequence types:\n\n      Lists\n         The items of a list are arbitrary Python objects.  Lists are\n         formed by placing a comma-separated list of expressions in\n         square brackets. (Note that there are no special cases needed\n         to form lists of length 0 or 1.)\n\n      Byte Arrays\n         A bytearray object is a mutable array. They are created by\n         the built-in "bytearray()" constructor.  Aside from being\n         mutable (and hence unhashable), byte arrays otherwise provide\n         the same interface and functionality as immutable bytes\n         objects.\n\n      The extension module "array" provides an additional example of a\n      mutable sequence type, as does the "collections" module.\n\nSet types\n   These represent unordered, finite sets of unique, immutable\n   objects. As such, they cannot be indexed by any subscript. However,\n   they can be iterated over, and the built-in function "len()"\n   returns the number of items in a set. Common uses for sets are fast\n   membership testing, removing duplicates from a sequence, and\n   computing mathematical operations such as intersection, union,\n   difference, and symmetric difference.\n\n   For set elements, the same immutability rules apply as for\n   dictionary keys. Note that numeric types obey the normal rules for\n   numeric comparison: if two numbers compare equal (e.g., "1" and\n   "1.0"), only one of them can be contained in a set.\n\n   There are currently two intrinsic set types:\n\n   Sets\n      These represent a mutable set. They are created by the built-in\n      "set()" constructor and can be modified afterwards by several\n      methods, such as "add()".\n\n   Frozen sets\n      These represent an immutable set.  They are created by the\n      built-in "frozenset()" constructor.  As a frozenset is immutable\n      and *hashable*, it can be used again as an element of another\n      set, or as a dictionary key.\n\nMappings\n   These represent finite sets of objects indexed by arbitrary index\n   sets. The subscript notation "a[k]" selects the item indexed by "k"\n   from the mapping "a"; this can be used in expressions and as the\n   target of assignments or "del" statements. The built-in function\n   "len()" returns the number of items in a mapping.\n\n   There is currently a single intrinsic mapping type:\n\n   Dictionaries\n      These represent finite sets of objects indexed by nearly\n      arbitrary values.  The only types of values not acceptable as\n      keys are values containing lists or dictionaries or other\n      mutable types that are compared by value rather than by object\n      identity, the reason being that the efficient implementation of\n      dictionaries requires a key\'s hash value to remain constant.\n      Numeric types used for keys obey the normal rules for numeric\n      comparison: if two numbers compare equal (e.g., "1" and "1.0")\n      then they can be used interchangeably to index the same\n      dictionary entry.\n\n      Dictionaries are mutable; they can be created by the "{...}"\n      notation (see section *Dictionary displays*).\n\n      The extension modules "dbm.ndbm" and "dbm.gnu" provide\n      additional examples of mapping types, as does the "collections"\n      module.\n\nCallable types\n   These are the types to which the function call operation (see\n   section *Calls*) can be applied:\n\n   User-defined functions\n      A user-defined function object is created by a function\n      definition (see section *Function definitions*).  It should be\n      called with an argument list containing the same number of items\n      as the function\'s formal parameter list.\n\n      Special attributes:\n\n      +---------------------------+---------------------------------+-------------+\n      +===========================+=================================+=============+\n      | "__doc__"                 | The function\'s documentation    | Writable    |\n      +---------------------------+---------------------------------+-------------+\n      | "__name__"                | The function\'s name             | Writable    |\n      +---------------------------+---------------------------------+-------------+\n      | "__qualname__"            | The function\'s *qualified name* | Writable    |\n      +---------------------------+---------------------------------+-------------+\n      | "__module__"              | The name of the module the      | Writable    |\n      +---------------------------+---------------------------------+-------------+\n      | "__defaults__"            | A tuple containing default      | Writable    |\n      +---------------------------+---------------------------------+-------------+\n      | "__code__"                | The code object representing    | Writable    |\n      +---------------------------+---------------------------------+-------------+\n      | "__globals__"             | A reference to the dictionary   | Read-only   |\n      +---------------------------+---------------------------------+-------------+\n      | "__dict__"                | The namespace supporting        | Writable    |\n      +---------------------------+---------------------------------+-------------+\n      | "__closure__"             | "None" or a tuple of cells that | Read-only   |\n      +---------------------------+---------------------------------+-------------+\n      | "__annotations__"         | A dict containing annotations   | Writable    |\n      +---------------------------+---------------------------------+-------------+\n      | "__kwdefaults__"          | A dict containing defaults for  | Writable    |\n      +---------------------------+---------------------------------+-------------+\n\n      Most of the attributes labelled "Writable" check the type of the\n      assigned value.\n\n      Function objects also support getting and setting arbitrary\n      attributes, which can be used, for example, to attach metadata\n      to functions.  Regular attribute dot-notation is used to get and\n      set such attributes. *Note that the current implementation only\n      supports function attributes on user-defined functions. Function\n      attributes on built-in functions may be supported in the\n      future.*\n\n      Additional information about a function\'s definition can be\n      retrieved from its code object; see the description of internal\n      types below.\n\n   Instance methods\n      An instance method object combines a class, a class instance and\n      any callable object (normally a user-defined function).\n\n      Special read-only attributes: "__self__" is the class instance\n      object, "__func__" is the function object; "__doc__" is the\n      method\'s documentation (same as "__func__.__doc__"); "__name__"\n      is the method name (same as "__func__.__name__"); "__module__"\n      is the name of the module the method was defined in, or "None"\n      if unavailable.\n\n      Methods also support accessing (but not setting) the arbitrary\n      function attributes on the underlying function object.\n\n      User-defined method objects may be created when getting an\n      attribute of a class (perhaps via an instance of that class), if\n      that attribute is a user-defined function object or a class\n      method object.\n\n      When an instance method object is created by retrieving a user-\n      defined function object from a class via one of its instances,\n      its "__self__" attribute is the instance, and the method object\n      is said to be bound.  The new method\'s "__func__" attribute is\n      the original function object.\n\n      When a user-defined method object is created by retrieving\n      another method object from a class or instance, the behaviour is\n      the same as for a function object, except that the "__func__"\n      attribute of the new instance is not the original method object\n      but its "__func__" attribute.\n\n      When an instance method object is created by retrieving a class\n      method object from a class or instance, its "__self__" attribute\n      is the class itself, and its "__func__" attribute is the\n      function object underlying the class method.\n\n      When an instance method object is called, the underlying\n      function ("__func__") is called, inserting the class instance\n      ("__self__") in front of the argument list.  For instance, when\n      "C" is a class which contains a definition for a function "f()",\n      and "x" is an instance of "C", calling "x.f(1)" is equivalent to\n      calling "C.f(x, 1)".\n\n      When an instance method object is derived from a class method\n      object, the "class instance" stored in "__self__" will actually\n      be the class itself, so that calling either "x.f(1)" or "C.f(1)"\n      is equivalent to calling "f(C,1)" where "f" is the underlying\n      function.\n\n      Note that the transformation from function object to instance\n      method object happens each time the attribute is retrieved from\n      the instance.  In some cases, a fruitful optimization is to\n      assign the attribute to a local variable and call that local\n      variable. Also notice that this transformation only happens for\n      user-defined functions; other callable objects (and all non-\n      callable objects) are retrieved without transformation.  It is\n      also important to note that user-defined functions which are\n      attributes of a class instance are not converted to bound\n      methods; this *only* happens when the function is an attribute\n      of the class.\n\n   Generator functions\n      A function or method which uses the "yield" statement (see\n      section *The yield statement*) is called a *generator function*.\n      Such a function, when called, always returns an iterator object\n      which can be used to execute the body of the function:  calling\n      the iterator\'s "iterator.__next__()" method will cause the\n      function to execute until it provides a value using the "yield"\n      statement.  When the function executes a "return" statement or\n      falls off the end, a "StopIteration" exception is raised and the\n      iterator will have reached the end of the set of values to be\n      returned.\n\n   Built-in functions\n      A built-in function object is a wrapper around a C function.\n      Examples of built-in functions are "len()" and "math.sin()"\n      ("math" is a standard built-in module). The number and type of\n      the arguments are determined by the C function. Special read-\n      only attributes: "__doc__" is the function\'s documentation\n      string, or "None" if unavailable; "__name__" is the function\'s\n      name; "__self__" is set to "None" (but see the next item);\n      "__module__" is the name of the module the function was defined\n      in or "None" if unavailable.\n\n   Built-in methods\n      This is really a different disguise of a built-in function, this\n      time containing an object passed to the C function as an\n      implicit extra argument.  An example of a built-in method is\n      "alist.append()", assuming *alist* is a list object. In this\n      case, the special read-only attribute "__self__" is set to the\n      object denoted by *alist*.\n\n   Classes\n      Classes are callable.  These objects normally act as factories\n      for new instances of themselves, but variations are possible for\n      class types that override "__new__()".  The arguments of the\n      call are passed to "__new__()" and, in the typical case, to\n      "__init__()" to initialize the new instance.\n\n   Class Instances\n      Instances of arbitrary classes can be made callable by defining\n      a "__call__()" method in their class.\n\nModules\n   Modules are a basic organizational unit of Python code, and are\n   created by the *import system* as invoked either by the "import"\n   statement (see "import"), or by calling functions such as\n   "importlib.import_module()" and built-in "__import__()".  A module\n   object has a namespace implemented by a dictionary object (this is\n   the dictionary referenced by the "__globals__" attribute of\n   functions defined in the module).  Attribute references are\n   translated to lookups in this dictionary, e.g., "m.x" is equivalent\n   to "m.__dict__["x"]". A module object does not contain the code\n   object used to initialize the module (since it isn\'t needed once\n   the initialization is done).\n\n   Attribute assignment updates the module\'s namespace dictionary,\n   e.g., "m.x = 1" is equivalent to "m.__dict__["x"] = 1".\n\n   Special read-only attribute: "__dict__" is the module\'s namespace\n   as a dictionary object.\n\n   **CPython implementation detail:** Because of the way CPython\n   clears module dictionaries, the module dictionary will be cleared\n   when the module falls out of scope even if the dictionary still has\n   live references.  To avoid this, copy the dictionary or keep the\n   module around while using its dictionary directly.\n\n   Predefined (writable) attributes: "__name__" is the module\'s name;\n   "__doc__" is the module\'s documentation string, or "None" if\n   unavailable; "__file__" is the pathname of the file from which the\n   module was loaded, if it was loaded from a file. The "__file__"\n   attribute may be missing for certain types of modules, such as C\n   modules that are statically linked into the interpreter; for\n   extension modules loaded dynamically from a shared library, it is\n   the pathname of the shared library file.\n\nCustom classes\n   Custom class types are typically created by class definitions (see\n   section *Class definitions*).  A class has a namespace implemented\n   by a dictionary object. Class attribute references are translated\n   to lookups in this dictionary, e.g., "C.x" is translated to\n   "C.__dict__["x"]" (although there are a number of hooks which allow\n   for other means of locating attributes). When the attribute name is\n   not found there, the attribute search continues in the base\n   classes. This search of the base classes uses the C3 method\n   resolution order which behaves correctly even in the presence of\n   \'diamond\' inheritance structures where there are multiple\n   inheritance paths leading back to a common ancestor. Additional\n   details on the C3 MRO used by Python can be found in the\n   documentation accompanying the 2.3 release at\n   http://www.python.org/download/releases/2.3/mro/.\n\n   When a class attribute reference (for class "C", say) would yield a\n   class method object, it is transformed into an instance method\n   object whose "__self__" attributes is "C".  When it would yield a\n   static method object, it is transformed into the object wrapped by\n   the static method object. See section *Implementing Descriptors*\n   for another way in which attributes retrieved from a class may\n   differ from those actually contained in its "__dict__".\n\n   Class attribute assignments update the class\'s dictionary, never\n   the dictionary of a base class.\n\n   A class object can be called (see above) to yield a class instance\n   (see below).\n\n   Special attributes: "__name__" is the class name; "__module__" is\n   the module name in which the class was defined; "__dict__" is the\n   dictionary containing the class\'s namespace; "__bases__" is a tuple\n   (possibly empty or a singleton) containing the base classes, in the\n   order of their occurrence in the base class list; "__doc__" is the\n   class\'s documentation string, or None if undefined.\n\nClass instances\n   A class instance is created by calling a class object (see above).\n   A class instance has a namespace implemented as a dictionary which\n   is the first place in which attribute references are searched.\n   When an attribute is not found there, and the instance\'s class has\n   an attribute by that name, the search continues with the class\n   attributes.  If a class attribute is found that is a user-defined\n   function object, it is transformed into an instance method object\n   whose "__self__" attribute is the instance.  Static method and\n   class method objects are also transformed; see above under\n   "Classes".  See section *Implementing Descriptors* for another way\n   in which attributes of a class retrieved via its instances may\n   differ from the objects actually stored in the class\'s "__dict__".\n   If no class attribute is found, and the object\'s class has a\n   "__getattr__()" method, that is called to satisfy the lookup.\n\n   Attribute assignments and deletions update the instance\'s\n   dictionary, never a class\'s dictionary.  If the class has a\n   "__setattr__()" or "__delattr__()" method, this is called instead\n   of updating the instance dictionary directly.\n\n   Class instances can pretend to be numbers, sequences, or mappings\n   if they have methods with certain special names.  See section\n   *Special method names*.\n\n   Special attributes: "__dict__" is the attribute dictionary;\n   "__class__" is the instance\'s class.\n\nI/O objects (also known as file objects)\n   A *file object* represents an open file.  Various shortcuts are\n   available to create file objects: the "open()" built-in function,\n   and also "os.popen()", "os.fdopen()", and the "makefile()" method\n   of socket objects (and perhaps by other functions or methods\n   provided by extension modules).\n\n   The objects "sys.stdin", "sys.stdout" and "sys.stderr" are\n   initialized to file objects corresponding to the interpreter\'s\n   standard input, output and error streams; they are all open in text\n   mode and therefore follow the interface defined by the\n   "io.TextIOBase" abstract class.\n\nInternal types\n   A few types used internally by the interpreter are exposed to the\n   user. Their definitions may change with future versions of the\n   interpreter, but they are mentioned here for completeness.\n\n   Code objects\n      Code objects represent *byte-compiled* executable Python code,\n      or *bytecode*. The difference between a code object and a\n      function object is that the function object contains an explicit\n      reference to the function\'s globals (the module in which it was\n      defined), while a code object contains no context; also the\n      default argument values are stored in the function object, not\n      in the code object (because they represent values calculated at\n      run-time).  Unlike function objects, code objects are immutable\n      and contain no references (directly or indirectly) to mutable\n      objects.\n\n      Special read-only attributes: "co_name" gives the function name;\n      "co_argcount" is the number of positional arguments (including\n      arguments with default values); "co_nlocals" is the number of\n      local variables used by the function (including arguments);\n      "co_varnames" is a tuple containing the names of the local\n      variables (starting with the argument names); "co_cellvars" is a\n      tuple containing the names of local variables that are\n      referenced by nested functions; "co_freevars" is a tuple\n      containing the names of free variables; "co_code" is a string\n      representing the sequence of bytecode instructions; "co_consts"\n      is a tuple containing the literals used by the bytecode;\n      "co_names" is a tuple containing the names used by the bytecode;\n      "co_filename" is the filename from which the code was compiled;\n      "co_firstlineno" is the first line number of the function;\n      "co_lnotab" is a string encoding the mapping from bytecode\n      offsets to line numbers (for details see the source code of the\n      interpreter); "co_stacksize" is the required stack size\n      (including local variables); "co_flags" is an integer encoding a\n      number of flags for the interpreter.\n\n      The following flag bits are defined for "co_flags": bit "0x04"\n      is set if the function uses the "*arguments" syntax to accept an\n      arbitrary number of positional arguments; bit "0x08" is set if\n      the function uses the "**keywords" syntax to accept arbitrary\n      keyword arguments; bit "0x20" is set if the function is a\n      generator.\n\n      Future feature declarations ("from __future__ import division")\n      also use bits in "co_flags" to indicate whether a code object\n      was compiled with a particular feature enabled: bit "0x2000" is\n      set if the function was compiled with future division enabled;\n      bits "0x10" and "0x1000" were used in earlier versions of\n      Python.\n\n      Other bits in "co_flags" are reserved for internal use.\n\n      If a code object represents a function, the first item in\n      "co_consts" is the documentation string of the function, or\n      "None" if undefined.\n\n   Frame objects\n      Frame objects represent execution frames.  They may occur in\n      traceback objects (see below).\n\n      Special read-only attributes: "f_back" is to the previous stack\n      frame (towards the caller), or "None" if this is the bottom\n      stack frame; "f_code" is the code object being executed in this\n      frame; "f_locals" is the dictionary used to look up local\n      variables; "f_globals" is used for global variables;\n      "f_builtins" is used for built-in (intrinsic) names; "f_lasti"\n      gives the precise instruction (this is an index into the\n      bytecode string of the code object).\n\n      Special writable attributes: "f_trace", if not "None", is a\n      function called at the start of each source code line (this is\n      used by the debugger); "f_lineno" is the current line number of\n      the frame --- writing to this from within a trace function jumps\n      to the given line (only for the bottom-most frame).  A debugger\n      can implement a Jump command (aka Set Next Statement) by writing\n      to f_lineno.\n\n      Frame objects support one method:\n\n      frame.clear()\n\n         This method clears all references to local variables held by\n         the frame.  Also, if the frame belonged to a generator, the\n         generator is finalized.  This helps break reference cycles\n         involving frame objects (for example when catching an\n         exception and storing its traceback for later use).\n\n         "RuntimeError" is raised if the frame is currently executing.\n\n         New in version 3.4.\n\n   Traceback objects\n      Traceback objects represent a stack trace of an exception.  A\n      traceback object is created when an exception occurs.  When the\n      search for an exception handler unwinds the execution stack, at\n      each unwound level a traceback object is inserted in front of\n      the current traceback.  When an exception handler is entered,\n      the stack trace is made available to the program. (See section\n      *The try statement*.) It is accessible as the third item of the\n      tuple returned by "sys.exc_info()". When the program contains no\n      suitable handler, the stack trace is written (nicely formatted)\n      to the standard error stream; if the interpreter is interactive,\n      it is also made available to the user as "sys.last_traceback".\n\n      Special read-only attributes: "tb_next" is the next level in the\n      stack trace (towards the frame where the exception occurred), or\n      "None" if there is no next level; "tb_frame" points to the\n      execution frame of the current level; "tb_lineno" gives the line\n      number where the exception occurred; "tb_lasti" indicates the\n      precise instruction.  The line number and last instruction in\n      the traceback may differ from the line number of its frame\n      object if the exception occurred in a "try" statement with no\n      matching except clause or with a finally clause.\n\n   Slice objects\n      Slice objects are used to represent slices for "__getitem__()"\n      methods.  They are also created by the built-in "slice()"\n      function.\n\n      Special read-only attributes: "start" is the lower bound; "stop"\n      is the upper bound; "step" is the step value; each is "None" if\n      omitted.  These attributes can have any type.\n\n      Slice objects support one method:\n\n      slice.indices(self, length)\n\n         This method takes a single integer argument *length* and\n         computes information about the slice that the slice object\n         would describe if applied to a sequence of *length* items.\n         It returns a tuple of three integers; respectively these are\n         the *start* and *stop* indices and the *step* or stride\n         length of the slice. Missing or out-of-bounds indices are\n         handled in a manner consistent with regular slices.\n\n   Static method objects\n      Static method objects provide a way of defeating the\n      transformation of function objects to method objects described\n      above. A static method object is a wrapper around any other\n      object, usually a user-defined method object. When a static\n      method object is retrieved from a class or a class instance, the\n      object actually returned is the wrapped object, which is not\n      subject to any further transformation. Static method objects are\n      not themselves callable, although the objects they wrap usually\n      are. Static method objects are created by the built-in\n      "staticmethod()" constructor.\n\n   Class method objects\n      A class method object, like a static method object, is a wrapper\n      around another object that alters the way in which that object\n      is retrieved from classes and class instances. The behaviour of\n      class method objects upon such retrieval is described above,\n      under "User-defined methods". Class method objects are created\n      by the built-in "classmethod()" constructor.\n',
+ 'typesfunctions': '\nFunctions\n*********\n\nFunction objects are created by function definitions.  The only\noperation on a function object is to call it: "func(argument-list)".\n\nThere are really two flavors of function objects: built-in functions\nand user-defined functions.  Both support the same operation (to call\nthe function), but the implementation is different, hence the\ndifferent object types.\n\nSee *Function definitions* for more information.\n',
+ 'typesmapping': '\nMapping Types --- "dict"\n************************\n\nA *mapping* object maps *hashable* values to arbitrary objects.\nMappings are mutable objects.  There is currently only one standard\nmapping type, the *dictionary*.  (For other containers see the built-\nin "list", "set", and "tuple" classes, and the "collections" module.)\n\nA dictionary\'s keys are *almost* arbitrary values.  Values that are\nnot *hashable*, that is, values containing lists, dictionaries or\nother mutable types (that are compared by value rather than by object\nidentity) may not be used as keys.  Numeric types used for keys obey\nthe normal rules for numeric comparison: if two numbers compare equal\n(such as "1" and "1.0") then they can be used interchangeably to index\nthe same dictionary entry.  (Note however, that since computers store\nfloating-point numbers as approximations it is usually unwise to use\nthem as dictionary keys.)\n\nDictionaries can be created by placing a comma-separated list of "key:\nvalue" pairs within braces, for example: "{\'jack\': 4098, \'sjoerd\':\n4127}" or "{4098: \'jack\', 4127: \'sjoerd\'}", or by the "dict"\nconstructor.\n\nclass class dict(**kwarg)\nclass class dict(mapping, **kwarg)\nclass class dict(iterable, **kwarg)\n\n   Return a new dictionary initialized from an optional positional\n   argument and a possibly empty set of keyword arguments.\n\n   If no positional argument is given, an empty dictionary is created.\n   If a positional argument is given and it is a mapping object, a\n   dictionary is created with the same key-value pairs as the mapping\n   object.  Otherwise, the positional argument must be an *iterator*\n   object.  Each item in the iterable must itself be an iterator with\n   exactly two objects.  The first object of each item becomes a key\n   in the new dictionary, and the second object the corresponding\n   value.  If a key occurs more than once, the last value for that key\n   becomes the corresponding value in the new dictionary.\n\n   If keyword arguments are given, the keyword arguments and their\n   values are added to the dictionary created from the positional\n   argument.  If a key being added is already present, the value from\n   the keyword argument replaces the value from the positional\n   argument.\n\n   To illustrate, the following examples all return a dictionary equal\n   to "{"one": 1, "two": 2, "three": 3}":\n\n      >>> a = dict(one=1, two=2, three=3)\n      >>> b = {\'one\': 1, \'two\': 2, \'three\': 3}\n      >>> c = dict(zip([\'one\', \'two\', \'three\'], [1, 2, 3]))\n      >>> d = dict([(\'two\', 2), (\'one\', 1), (\'three\', 3)])\n      >>> e = dict({\'three\': 3, \'one\': 1, \'two\': 2})\n      >>> a == b == c == d == e\n      True\n\n   Providing keyword arguments as in the first example only works for\n   keys that are valid Python identifiers.  Otherwise, any valid keys\n   can be used.\n\n   These are the operations that dictionaries support (and therefore,\n   custom mapping types should support too):\n\n   len(d)\n\n      Return the number of items in the dictionary *d*.\n\n   d[key]\n\n      Return the item of *d* with key *key*.  Raises a "KeyError" if\n      *key* is not in the map.\n\n      If a subclass of dict defines a method "__missing__()", if the\n      key *key* is not present, the "d[key]" operation calls that\n      method with the key *key* as argument.  The "d[key]" operation\n      then returns or raises whatever is returned or raised by the\n      "__missing__(key)" call if the key is not present. No other\n      operations or methods invoke "__missing__()". If "__missing__()"\n      is not defined, "KeyError" is raised. "__missing__()" must be a\n      method; it cannot be an instance variable:\n\n         >>> class Counter(dict):\n         ...     def __missing__(self, key):\n         ...         return 0\n         >>> c = Counter()\n         >>> c[\'red\']\n         0\n         >>> c[\'red\'] += 1\n         >>> c[\'red\']\n         1\n\n      See "collections.Counter" for a complete implementation\n      including other methods helpful for accumulating and managing\n      tallies.\n\n   d[key] = value\n\n      Set "d[key]" to *value*.\n\n   del d[key]\n\n      Remove "d[key]" from *d*.  Raises a "KeyError" if *key* is not\n      in the map.\n\n   key in d\n\n      Return "True" if *d* has a key *key*, else "False".\n\n   key not in d\n\n      Equivalent to "not key in d".\n\n   iter(d)\n\n      Return an iterator over the keys of the dictionary.  This is a\n      shortcut for "iter(d.keys())".\n\n   clear()\n\n      Remove all items from the dictionary.\n\n   copy()\n\n      Return a shallow copy of the dictionary.\n\n   classmethod fromkeys(seq[, value])\n\n      Create a new dictionary with keys from *seq* and values set to\n      *value*.\n\n      "fromkeys()" is a class method that returns a new dictionary.\n      *value* defaults to "None".\n\n   get(key[, default])\n\n      Return the value for *key* if *key* is in the dictionary, else\n      *default*. If *default* is not given, it defaults to "None", so\n      that this method never raises a "KeyError".\n\n   items()\n\n      Return a new view of the dictionary\'s items ("(key, value)"\n      pairs). See the *documentation of view objects*.\n\n   keys()\n\n      Return a new view of the dictionary\'s keys.  See the\n      *documentation of view objects*.\n\n   pop(key[, default])\n\n      If *key* is in the dictionary, remove it and return its value,\n      else return *default*.  If *default* is not given and *key* is\n      not in the dictionary, a "KeyError" is raised.\n\n   popitem()\n\n      Remove and return an arbitrary "(key, value)" pair from the\n      dictionary.\n\n      "popitem()" is useful to destructively iterate over a\n      dictionary, as often used in set algorithms.  If the dictionary\n      is empty, calling "popitem()" raises a "KeyError".\n\n   setdefault(key[, default])\n\n      If *key* is in the dictionary, return its value.  If not, insert\n      *key* with a value of *default* and return *default*.  *default*\n      defaults to "None".\n\n   update([other])\n\n      Update the dictionary with the key/value pairs from *other*,\n      overwriting existing keys.  Return "None".\n\n      "update()" accepts either another dictionary object or an\n      iterable of key/value pairs (as tuples or other iterables of\n      length two).  If keyword arguments are specified, the dictionary\n      is then updated with those key/value pairs: "d.update(red=1,\n      blue=2)".\n\n   values()\n\n      Return a new view of the dictionary\'s values.  See the\n      *documentation of view objects*.\n\nSee also:\n\n   "types.MappingProxyType" can be used to create a read-only view of\n   a "dict".\n\n\nDictionary view objects\n=======================\n\nThe objects returned by "dict.keys()", "dict.values()" and\n"dict.items()" are *view objects*.  They provide a dynamic view on the\ndictionary\'s entries, which means that when the dictionary changes,\nthe view reflects these changes.\n\nDictionary views can be iterated over to yield their respective data,\nand support membership tests:\n\nlen(dictview)\n\n   Return the number of entries in the dictionary.\n\niter(dictview)\n\n   Return an iterator over the keys, values or items (represented as\n   tuples of "(key, value)") in the dictionary.\n\n   Keys and values are iterated over in an arbitrary order which is\n   non-random, varies across Python implementations, and depends on\n   the dictionary\'s history of insertions and deletions. If keys,\n   values and items views are iterated over with no intervening\n   modifications to the dictionary, the order of items will directly\n   correspond.  This allows the creation of "(value, key)" pairs using\n   "zip()": "pairs = zip(d.values(), d.keys())".  Another way to\n   create the same list is "pairs = [(v, k) for (k, v) in d.items()]".\n\n   Iterating views while adding or deleting entries in the dictionary\n   may raise a "RuntimeError" or fail to iterate over all entries.\n\nx in dictview\n\n   Return "True" if *x* is in the underlying dictionary\'s keys, values\n   or items (in the latter case, *x* should be a "(key, value)"\n   tuple).\n\nKeys views are set-like since their entries are unique and hashable.\nIf all values are hashable, so that "(key, value)" pairs are unique\nand hashable, then the items view is also set-like.  (Values views are\nnot treated as set-like since the entries are generally not unique.)\nFor set-like views, all of the operations defined for the abstract\nbase class "collections.abc.Set" are available (for example, "==",\n"<", or "^").\n\nAn example of dictionary view usage:\n\n   >>> dishes = {\'eggs\': 2, \'sausage\': 1, \'bacon\': 1, \'spam\': 500}\n   >>> keys = dishes.keys()\n   >>> values = dishes.values()\n\n   >>> # iteration\n   >>> n = 0\n   >>> for val in values:\n   ...     n += val\n   >>> print(n)\n   504\n\n   >>> # keys and values are iterated over in the same order\n   >>> list(keys)\n   [\'eggs\', \'bacon\', \'sausage\', \'spam\']\n   >>> list(values)\n   [2, 1, 1, 500]\n\n   >>> # view objects are dynamic and reflect dict changes\n   >>> del dishes[\'eggs\']\n   >>> del dishes[\'sausage\']\n   >>> list(keys)\n   [\'spam\', \'bacon\']\n\n   >>> # set operations\n   >>> keys & {\'eggs\', \'bacon\', \'salad\'}\n   {\'bacon\'}\n   >>> keys ^ {\'sausage\', \'juice\'}\n   {\'juice\', \'sausage\', \'bacon\', \'spam\'}\n',
+ 'typesmethods': '\nMethods\n*******\n\nMethods are functions that are called using the attribute notation.\nThere are two flavors: built-in methods (such as "append()" on lists)\nand class instance methods.  Built-in methods are described with the\ntypes that support them.\n\nIf you access a method (a function defined in a class namespace)\nthrough an instance, you get a special object: a *bound method* (also\ncalled *instance method*) object. When called, it will add the "self"\nargument to the argument list.  Bound methods have two special read-\nonly attributes: "m.__self__" is the object on which the method\noperates, and "m.__func__" is the function implementing the method.\nCalling "m(arg-1, arg-2, ..., arg-n)" is completely equivalent to\ncalling "m.__func__(m.__self__, arg-1, arg-2, ..., arg-n)".\n\nLike function objects, bound method objects support getting arbitrary\nattributes.  However, since method attributes are actually stored on\nthe underlying function object ("meth.__func__"), setting method\nattributes on bound methods is disallowed.  Attempting to set an\nattribute on a method results in an "AttributeError" being raised.  In\norder to set a method attribute, you need to explicitly set it on the\nunderlying function object:\n\n   >>> class C:\n   ...     def method(self):\n   ...         pass\n   ...\n   >>> c = C()\n   >>> c.method.whoami = \'my name is method\'  # can\'t set on the method\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in <module>\n   AttributeError: \'method\' object has no attribute \'whoami\'\n   >>> c.method.__func__.whoami = \'my name is method\'\n   >>> c.method.whoami\n   \'my name is method\'\n\nSee *The standard type hierarchy* for more information.\n',
+ 'typesmodules': '\nModules\n*******\n\nThe only special operation on a module is attribute access: "m.name",\nwhere *m* is a module and *name* accesses a name defined in *m*\'s\nsymbol table. Module attributes can be assigned to.  (Note that the\n"import" statement is not, strictly speaking, an operation on a module\nobject; "import foo" does not require a module object named *foo* to\nexist, rather it requires an (external) *definition* for a module\nnamed *foo* somewhere.)\n\nA special attribute of every module is "__dict__". This is the\ndictionary containing the module\'s symbol table. Modifying this\ndictionary will actually change the module\'s symbol table, but direct\nassignment to the "__dict__" attribute is not possible (you can write\n"m.__dict__[\'a\'] = 1", which defines "m.a" to be "1", but you can\'t\nwrite "m.__dict__ = {}").  Modifying "__dict__" directly is not\nrecommended.\n\nModules built into the interpreter are written like this: "<module\n\'sys\' (built-in)>".  If loaded from a file, they are written as\n"<module \'os\' from \'/usr/local/lib/pythonX.Y/os.pyc\'>".\n',
+ 'typesseq': '\nSequence Types --- "list", "tuple", "range"\n*******************************************\n\nThere are three basic sequence types: lists, tuples, and range\nobjects. Additional sequence types tailored for processing of *binary\ndata* and *text strings* are described in dedicated sections.\n\n\nCommon Sequence Operations\n==========================\n\nThe operations in the following table are supported by most sequence\ntypes, both mutable and immutable. The "collections.abc.Sequence" ABC\nis provided to make it easier to correctly implement these operations\non custom sequence types.\n\nThis table lists the sequence operations sorted in ascending priority\n(operations in the same box have the same priority).  In the table,\n*s* and *t* are sequences of the same type, *n*, *i*, *j* and *k* are\nintegers and *x* is an arbitrary object that meets any type and value\nrestrictions imposed by *s*.\n\nThe "in" and "not in" operations have the same priorities as the\ncomparison operations. The "+" (concatenation) and "*" (repetition)\noperations have the same priority as the corresponding numeric\noperations.\n\n+----------------------------+----------------------------------+------------+\n| Operation                  | Result                           | Notes      |\n+============================+==================================+============+\n| "x in s"                   | "True" if an item of *s* is      | (1)        |\n+----------------------------+----------------------------------+------------+\n| "x not in s"               | "False" if an item of *s* is     | (1)        |\n+----------------------------+----------------------------------+------------+\n| "s + t"                    | the concatenation of *s* and *t* | (6)(7)     |\n+----------------------------+----------------------------------+------------+\n| "s * n" or "n * s"         | *n* shallow copies of *s*        | (2)(7)     |\n+----------------------------+----------------------------------+------------+\n| "s[i]"                     | *i*th item of *s*, origin 0      | (3)        |\n+----------------------------+----------------------------------+------------+\n| "s[i:j]"                   | slice of *s* from *i* to *j*     | (3)(4)     |\n+----------------------------+----------------------------------+------------+\n| "s[i:j:k]"                 | slice of *s* from *i* to *j*     | (3)(5)     |\n+----------------------------+----------------------------------+------------+\n+----------------------------+----------------------------------+------------+\n+----------------------------+----------------------------------+------------+\n+----------------------------+----------------------------------+------------+\n| "s.index(x[, i[, j]])"     | index of the first occurrence of | (8)        |\n+----------------------------+----------------------------------+------------+\n+----------------------------+----------------------------------+------------+\n\nSequences of the same type also support comparisons.  In particular,\ntuples and lists are compared lexicographically by comparing\ncorresponding elements. This means that to compare equal, every\nelement must compare equal and the two sequences must be of the same\ntype and have the same length.  (For full details see *Comparisons* in\nthe language reference.)\n\nNotes:\n\n1. While the "in" and "not in" operations are used only for simple\n   containment testing in the general case, some specialised sequences\n   (such as "str", "bytes" and "bytearray") also use them for\n   subsequence testing:\n\n      >>> "gg" in "eggs"\n      True\n\n2. Values of *n* less than "0" are treated as "0" (which yields an\n   empty sequence of the same type as *s*).  Note also that the copies\n   are shallow; nested structures are not copied.  This often haunts\n   new Python programmers; consider:\n\n      >>> lists = [[]] * 3\n      >>> lists\n      [[], [], []]\n      >>> lists[0].append(3)\n      >>> lists\n      [[3], [3], [3]]\n\n   What has happened is that "[[]]" is a one-element list containing\n   an empty list, so all three elements of "[[]] * 3" are (pointers\n   to) this single empty list.  Modifying any of the elements of\n   "lists" modifies this single list. You can create a list of\n   different lists this way:\n\n      >>> lists = [[] for i in range(3)]\n      >>> lists[0].append(3)\n      >>> lists[1].append(5)\n      >>> lists[2].append(7)\n      >>> lists\n      [[3], [5], [7]]\n\n3. If *i* or *j* is negative, the index is relative to the end of the\n   string: "len(s) + i" or "len(s) + j" is substituted.  But note that\n   "-0" is still "0".\n\n4. The slice of *s* from *i* to *j* is defined as the sequence of\n   items with index *k* such that "i <= k < j".  If *i* or *j* is\n   greater than "len(s)", use "len(s)".  If *i* is omitted or "None",\n   use "0".  If *j* is omitted or "None", use "len(s)".  If *i* is\n   greater than or equal to *j*, the slice is empty.\n\n5. The slice of *s* from *i* to *j* with step *k* is defined as the\n   sequence of items with index  "x = i + n*k" such that "0 <= n <\n   (j-i)/k".  In other words, the indices are "i", "i+k", "i+2*k",\n   "i+3*k" and so on, stopping when *j* is reached (but never\n   including *j*).  If *i* or *j* is greater than "len(s)", use\n   "len(s)".  If *i* or *j* are omitted or "None", they become "end"\n   values (which end depends on the sign of *k*).  Note, *k* cannot be\n   zero. If *k* is "None", it is treated like "1".\n\n6. Concatenating immutable sequences always results in a new object.\n   This means that building up a sequence by repeated concatenation\n   will have a quadratic runtime cost in the total sequence length.\n   To get a linear runtime cost, you must switch to one of the\n   alternatives below:\n\n   * if concatenating "str" objects, you can build a list and use\n     "str.join()" at the end or else write to a "io.StringIO" instance\n     and retrieve its value when complete\n\n   * if concatenating "bytes" objects, you can similarly use\n     "bytes.join()" or "io.BytesIO", or you can do in-place\n     concatenation with a "bytearray" object.  "bytearray" objects are\n     mutable and have an efficient overallocation mechanism\n\n   * if concatenating "tuple" objects, extend a "list" instead\n\n   * for other types, investigate the relevant class documentation\n\n7. Some sequence types (such as "range") only support item sequences\n   that follow specific patterns, and hence don\'t support sequence\n   concatenation or repetition.\n\n8. "index" raises "ValueError" when *x* is not found in *s*. When\n   supported, the additional arguments to the index method allow\n   efficient searching of subsections of the sequence. Passing the\n   extra arguments is roughly equivalent to using "s[i:j].index(x)",\n   only without copying any data and with the returned index being\n   relative to the start of the sequence rather than the start of the\n   slice.\n\n\nImmutable Sequence Types\n========================\n\nThe only operation that immutable sequence types generally implement\nthat is not also implemented by mutable sequence types is support for\nthe "hash()" built-in.\n\nThis support allows immutable sequences, such as "tuple" instances, to\nbe used as "dict" keys and stored in "set" and "frozenset" instances.\n\nAttempting to hash an immutable sequence that contains unhashable\nvalues will result in "TypeError".\n\n\nMutable Sequence Types\n======================\n\nThe operations in the following table are defined on mutable sequence\ntypes. The "collections.abc.MutableSequence" ABC is provided to make\nit easier to correctly implement these operations on custom sequence\ntypes.\n\nIn the table *s* is an instance of a mutable sequence type, *t* is any\niterable object and *x* is an arbitrary object that meets any type and\nvalue restrictions imposed by *s* (for example, "bytearray" only\naccepts integers that meet the value restriction "0 <= x <= 255").\n\n+--------------------------------+----------------------------------+-----------------------+\n| Operation                      | Result                           | Notes                 |\n+================================+==================================+=======================+\n+--------------------------------+----------------------------------+-----------------------+\n+--------------------------------+----------------------------------+-----------------------+\n+--------------------------------+----------------------------------+-----------------------+\n| "s[i:j:k] = t"                 | the elements of "s[i:j:k]" are   | (1)                   |\n+--------------------------------+----------------------------------+-----------------------+\n+--------------------------------+----------------------------------+-----------------------+\n+--------------------------------+----------------------------------+-----------------------+\n| "s.clear()"                    | removes all items from "s" (same | (5)                   |\n+--------------------------------+----------------------------------+-----------------------+\n| "s.copy()"                     | creates a shallow copy of "s"    | (5)                   |\n+--------------------------------+----------------------------------+-----------------------+\n+--------------------------------+----------------------------------+-----------------------+\n+--------------------------------+----------------------------------+-----------------------+\n| "s.pop([i])"                   | retrieves the item at *i* and    | (2)                   |\n+--------------------------------+----------------------------------+-----------------------+\n| "s.remove(x)"                  | remove the first item from *s*   | (3)                   |\n+--------------------------------+----------------------------------+-----------------------+\n| "s.reverse()"                  | reverses the items of *s* in     | (4)                   |\n+--------------------------------+----------------------------------+-----------------------+\n\nNotes:\n\n1. *t* must have the same length as the slice it is replacing.\n\n2. The optional argument *i* defaults to "-1", so that by default the\n   last item is removed and returned.\n\n3. "remove" raises "ValueError" when *x* is not found in *s*.\n\n4. The "reverse()" method modifies the sequence in place for economy\n   of space when reversing a large sequence.  To remind users that it\n   operates by side effect, it does not return the reversed sequence.\n\n5. "clear()" and "copy()" are included for consistency with the\n   interfaces of mutable containers that don\'t support slicing\n   operations (such as "dict" and "set")\n\n   New in version 3.3: "clear()" and "copy()" methods.\n\n\nLists\n=====\n\nLists are mutable sequences, typically used to store collections of\nhomogeneous items (where the precise degree of similarity will vary by\napplication).\n\nclass class list([iterable])\n\n   Lists may be constructed in several ways:\n\n   * Using a pair of square brackets to denote the empty list: "[]"\n\n   * Using square brackets, separating items with commas: "[a]", "[a,\n     b, c]"\n\n   * Using a list comprehension: "[x for x in iterable]"\n\n   * Using the type constructor: "list()" or "list(iterable)"\n\n   The constructor builds a list whose items are the same and in the\n   same order as *iterable*\'s items.  *iterable* may be either a\n   sequence, a container that supports iteration, or an iterator\n   object.  If *iterable* is already a list, a copy is made and\n   returned, similar to "iterable[:]". For example, "list(\'abc\')"\n   returns "[\'a\', \'b\', \'c\']" and "list( (1, 2, 3) )" returns "[1, 2,\n   3]". If no argument is given, the constructor creates a new empty\n   list, "[]".\n\n   Many other operations also produce lists, including the "sorted()"\n   built-in.\n\n   Lists implement all of the *common* and *mutable* sequence\n   operations. Lists also provide the following additional method:\n\n   sort(*, key=None, reverse=None)\n\n      This method sorts the list in place, using only "<" comparisons\n      between items. Exceptions are not suppressed - if any comparison\n      operations fail, the entire sort operation will fail (and the\n      list will likely be left in a partially modified state).\n\n      "sort()" accepts two arguments that can only be passed by\n      keyword (*keyword-only arguments*):\n\n      *key* specifies a function of one argument that is used to\n      extract a comparison key from each list element (for example,\n      "key=str.lower"). The key corresponding to each item in the list\n      is calculated once and then used for the entire sorting process.\n      The default value of "None" means that list items are sorted\n      directly without calculating a separate key value.\n\n      The "functools.cmp_to_key()" utility is available to convert a\n      2.x style *cmp* function to a *key* function.\n\n      *reverse* is a boolean value.  If set to "True", then the list\n      elements are sorted as if each comparison were reversed.\n\n      This method modifies the sequence in place for economy of space\n      when sorting a large sequence.  To remind users that it operates\n      by side effect, it does not return the sorted sequence (use\n      "sorted()" to explicitly request a new sorted list instance).\n\n      The "sort()" method is guaranteed to be stable.  A sort is\n      stable if it guarantees not to change the relative order of\n      elements that compare equal --- this is helpful for sorting in\n      multiple passes (for example, sort by department, then by salary\n      grade).\n\n      **CPython implementation detail:** While a list is being sorted,\n      the effect of attempting to mutate, or even inspect, the list is\n      undefined.  The C implementation of Python makes the list appear\n      empty for the duration, and raises "ValueError" if it can detect\n      that the list has been mutated during a sort.\n\n\nTuples\n======\n\nTuples are immutable sequences, typically used to store collections of\nheterogeneous data (such as the 2-tuples produced by the "enumerate()"\nbuilt-in). Tuples are also used for cases where an immutable sequence\nof homogeneous data is needed (such as allowing storage in a "set" or\n"dict" instance).\n\nclass class tuple([iterable])\n\n   Tuples may be constructed in a number of ways:\n\n   * Using a pair of parentheses to denote the empty tuple: "()"\n\n   * Using a trailing comma for a singleton tuple: "a," or "(a,)"\n\n   * Separating items with commas: "a, b, c" or "(a, b, c)"\n\n   * Using the "tuple()" built-in: "tuple()" or "tuple(iterable)"\n\n   The constructor builds a tuple whose items are the same and in the\n   same order as *iterable*\'s items.  *iterable* may be either a\n   sequence, a container that supports iteration, or an iterator\n   object.  If *iterable* is already a tuple, it is returned\n   unchanged. For example, "tuple(\'abc\')" returns "(\'a\', \'b\', \'c\')"\n   and "tuple( [1, 2, 3] )" returns "(1, 2, 3)". If no argument is\n   given, the constructor creates a new empty tuple, "()".\n\n   Note that it is actually the comma which makes a tuple, not the\n   parentheses. The parentheses are optional, except in the empty\n   tuple case, or when they are needed to avoid syntactic ambiguity.\n   For example, "f(a, b, c)" is a function call with three arguments,\n   while "f((a, b, c))" is a function call with a 3-tuple as the sole\n   argument.\n\n   Tuples implement all of the *common* sequence operations.\n\nFor heterogeneous collections of data where access by name is clearer\nthan access by index, "collections.namedtuple()" may be a more\nappropriate choice than a simple tuple object.\n\n\nRanges\n======\n\nThe "range" type represents an immutable sequence of numbers and is\ncommonly used for looping a specific number of times in "for" loops.\n\nclass class range(stop)\nclass class range(start, stop[, step])\n\n   The arguments to the range constructor must be integers (either\n   built-in "int" or any object that implements the "__index__"\n   special method).  If the *step* argument is omitted, it defaults to\n   "1". If the *start* argument is omitted, it defaults to "0". If\n   *step* is zero, "ValueError" is raised.\n\n   For a positive *step*, the contents of a range "r" are determined\n   by the formula "r[i] = start + step*i" where "i >= 0" and "r[i] <\n   stop".\n\n   For a negative *step*, the contents of the range are still\n   determined by the formula "r[i] = start + step*i", but the\n   constraints are "i >= 0" and "r[i] > stop".\n\n   A range object will be empty if "r[0]" does not meet the value\n   constraint. Ranges do support negative indices, but these are\n   interpreted as indexing from the end of the sequence determined by\n   the positive indices.\n\n   Ranges containing absolute values larger than "sys.maxsize" are\n   permitted but some features (such as "len()") may raise\n   "OverflowError".\n\n   Range examples:\n\n      >>> list(range(10))\n      [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]\n      >>> list(range(1, 11))\n      [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]\n      >>> list(range(0, 30, 5))\n      [0, 5, 10, 15, 20, 25]\n      >>> list(range(0, 10, 3))\n      [0, 3, 6, 9]\n      >>> list(range(0, -10, -1))\n      [0, -1, -2, -3, -4, -5, -6, -7, -8, -9]\n      >>> list(range(0))\n      []\n      >>> list(range(1, 0))\n      []\n\n   Ranges implement all of the *common* sequence operations except\n   concatenation and repetition (due to the fact that range objects\n   can only represent sequences that follow a strict pattern and\n   repetition and concatenation will usually violate that pattern).\n\nThe advantage of the "range" type over a regular "list" or "tuple" is\nthat a "range" object will always take the same (small) amount of\nmemory, no matter the size of the range it represents (as it only\nstores the "start", "stop" and "step" values, calculating individual\nitems and subranges as needed).\n\nRange objects implement the "collections.abc.Sequence" ABC, and\nprovide features such as containment tests, element index lookup,\nslicing and support for negative indices (see *Sequence Types ---\nlist, tuple, range*):\n\n>>> r = range(0, 20, 2)\n>>> r\nrange(0, 20, 2)\n>>> 11 in r\nFalse\n>>> 10 in r\nTrue\n>>> r.index(10)\n5\n>>> r[5]\n10\n>>> r[:5]\nrange(0, 10, 2)\n>>> r[-1]\n18\n\nTesting range objects for equality with "==" and "!=" compares them as\nsequences.  That is, two range objects are considered equal if they\nrepresent the same sequence of values.  (Note that two range objects\nthat compare equal might have different "start", "stop" and "step"\nattributes, for example "range(0) == range(2, 1, 3)" or "range(0, 3,\n2) == range(0, 4, 2)".)\n\nChanged in version 3.2: Implement the Sequence ABC. Support slicing\nand negative indices. Test "int" objects for membership in constant\ntime instead of iterating through all items.\n\nChanged in version 3.3: Define \'==\' and \'!=\' to compare range objects\nbased on the sequence of values they define (instead of comparing\nbased on object identity).\n\nNew in version 3.3: The "start", "stop" and "step" attributes.\n',

The "reverse()" method modifies the sequence in place for economy\n   of space when reversing a large sequence.  To remind users that it\n   operates by side effect, it does not return the reversed sequence.\n\n5. "clear()" and "copy()" are included for consistency with the\n   interfaces of mutable containers that don\'t support slicing\n   operations (such as "dict" and "set")\n\n   New in version 3.3: "clear()" and "copy()" methods.\n',
+ 'unary': '\nUnary arithmetic and bitwise operations\n***************************************\n\nAll unary arithmetic and bitwise operations have the same priority:\n\n   u_expr ::= power | "-" u_expr | "+" u_expr | "~" u_expr\n\nThe unary "-" (minus) operator yields the negation of its numeric\nargument.\n\nThe unary "+" (plus) operator yields its numeric argument unchanged.\n\nThe unary "~" (invert) operator yields the bitwise inversion of its\ninteger argument.  The bitwise inversion of "x" is defined as\n"-(x+1)".  It only applies to integral numbers.\n\nIn all three cases, if the argument does not have the proper type, a\n"TypeError" exception is raised.\n',

A "continue" statement\nexecuted in the first suite skips the rest of the suite and goes back\nto testing the expression.\n',
+ 'with': '\nThe "with" statement\n********************\n\nThe "with" statement is used to wrap the execution of a block with\nmethods defined by a context manager (see section *With Statement\nContext Managers*). This allows common "try"..."except"..."finally"\nusage patterns to be encapsulated for convenient reuse.\n\n   with_stmt ::= "with" with_item ("," with_item)* ":" suite\n   with_item ::= expression ["as" target]\n\nThe execution of the "with" statement with one "item" proceeds as\nfollows:\n\n1. The context expression (the expression given in the "with_item") is\n   evaluated to obtain a context manager.\n\n2. The context manager\'s "__exit__()" is loaded for later use.\n\n3. The context manager\'s "__enter__()" method is invoked.\n\n4. If a target was included in the "with" statement, the return value\n   from "__enter__()" is assigned to it.\n\n   Note: The "with" statement guarantees that if the "__enter__()" method\n     returns without an error, then "__exit__()" will always be\n     called. Thus, if an error occurs during the assignment to the\n     target list, it will be treated the same as an error occurring\n     within the suite would be. See step 6 below.\n\n5. The suite is executed.\n\n6. The context manager\'s "__exit__()" method is invoked.  If an\n   exception caused the suite to be exited, its type, value, and\n   traceback are passed as arguments to "__exit__()". Otherwise, three\n   "None" arguments are supplied.\n\n   If the suite was exited due to an exception, and the return value\n   from the "__exit__()" method was false, the exception is reraised.\n   If the return value was true, the exception is suppressed, and\n   execution continues with the statement following the "with"\n   statement.\n\n   If the suite was exited for any reason other than an exception, the\n   return value from "__exit__()" is ignored, and execution proceeds\n   at the normal location for the kind of exit that was taken.\n\nWith more than one item, the context managers are processed as if\nmultiple "with" statements were nested:\n\n   with A() as a, B() as b:\n       suite\n\nis equivalent to\n\n   with A() as a:\n       with B() as b:\n           suite\n\nChanged in version 3.1: Support for multiple context expressions.\n\nSee also:\n\n   **PEP 0343** - The "with" statement\n      The specification, background, and examples for the Python\n      "with" statement.\n',
+ 'yield': '\nThe "yield" statement\n*********************\n\n   yield_stmt ::= yield_expression\n\nA "yield" statement is semantically equivalent to a *yield\nexpression*. The yield statement can be used to omit the parentheses\nthat would otherwise be required in the equivalent yield expression\nstatement. For example, the yield statements\n\n   yield <expr>\n   yield from <expr>\n\nare equivalent to the yield expression statements\n\n   (yield <expr>)\n   (yield from <expr>)\n\nYield expressions and statements are only used when defining a\n*generator* function, and are only used in the body of the generator\nfunction.  Using yield in a function definition is sufficient to cause\nthat definition to create a generator function instead of a normal\nfunction.\n\nFor full details of "yield" semantics, refer to the *Yield\nexpressions* section.\n'}

+r"""Support for regular expressions (RE).
+
+This module provides regular expression matching operations similar to
+those found in Perl.  It supports both 8-bit and Unicode strings; both
+the pattern and the strings being processed can contain null bytes and
+characters outside the US ASCII range.
+
+Regular expressions can contain both special and ordinary characters.
+Most ordinary characters, like "A", "a", or "0", are the simplest
+regular expressions; they simply match themselves.  You can
+concatenate ordinary characters, so last matches the string 'last'.
+
+The special characters are:
+    "."      Matches any character except a newline.
+    "^"      Matches the start of the string.
+    "$"      Matches the end of the string or just before the newline at
+             the end of the string.
+    "*"      Matches 0 or more (greedy) repetitions of the preceding RE.
+             Greedy means that it will match as many repetitions as possible.
+    "+"      Matches 1 or more (greedy) repetitions of the preceding RE.
+    "?"      Matches 0 or 1 (greedy) of the preceding RE.
+    *?,+?,?? Non-greedy versions of the previous three special characters.
+    {m,n}    Matches from m to n repetitions of the preceding RE.
+    {m,n}?   Non-greedy version of the above.
+    "\\"     Either escapes special characters or signals a special sequence.
+    []       Indicates a set of characters.
+             A "^" as the first character indicates a complementing set.
+    "|"      A|B, creates an RE that will match either A or B.
+    (...)    Matches the RE inside the parentheses.
+             The contents can be retrieved or matched later in the string.
+    (?aiLmsux) Set the A, I, L, M, S, U, or X flag for the RE (see below).
+    (?:...)  Non-grouping version of regular parentheses.
+    (?P<name>...) The substring matched by the group is accessible by name.
+    (?P=name)     Matches the text matched earlier by the group named name.
+    (?#...)  A comment; ignored.
+    (?=...)  Matches if ... matches next, but doesn't consume the string.
+    (?!...)  Matches if ... doesn't match next.
+    (?<=...) Matches if preceded by ... (must be fixed length).
+    (?<!...) Matches if not preceded by ... (must be fixed length).
+    (?(id/name)yes|no) Matches yes pattern if the group with id/name matched,
+                       the (optional) no pattern otherwise.
+
+The special sequences consist of "\\" and a character from the list
+below.  If the ordinary character is not on the list, then the
+resulting RE will match the second character.
+    \number  Matches the contents of the group of the same number.
+    \A       Matches only at the start of the string.
+    \Z       Matches only at the end of the string.
+    \b       Matches the empty string, but only at the start or end of a word.
+    \B       Matches the empty string, but not at the start or end of a word.
+    \d       Matches any decimal digit; equivalent to the set [0-9] in
+             bytes patterns or string patterns with the ASCII flag.
+             In string patterns without the ASCII flag, it will match the whole
+             range of Unicode digits.
+    \D       Matches any non-digit character; equivalent to [^\d].
+    \s       Matches any whitespace character; equivalent to [ \t\n\r\f\v] in
+             bytes patterns or string patterns with the ASCII flag.
+             In string patterns without the ASCII flag, it will match the whole
+             range of Unicode whitespace characters.
+    \S       Matches any non-whitespace character; equivalent to [^\s].
+    \w       Matches any alphanumeric character; equivalent to [a-zA-Z0-9_]
+             in bytes patterns or string patterns with the ASCII flag.
+             In string patterns without the ASCII flag, it will match the
+             range of Unicode alphanumeric characters (letters plus digits
+             plus underscore).
+             With LOCALE, it will match the set [0-9_] plus characters defined
+             as letters for the current locale.
+    \W       Matches the complement of \w.
+    \\       Matches a literal backslash.
+
+This module exports the following functions:
+    match     Match a regular expression pattern to the beginning of a string.
+    fullmatch Match a regular expression pattern to all of a string.
+    search    Search a string for the presence of a pattern.
+    sub       Substitute occurrences of a pattern found in a string.
+    subn      Same as sub, but also return the number of substitutions made.
+    split     Split a string by the occurrences of a pattern.
+    findall   Find all occurrences of a pattern in a string.
+    finditer  Return an iterator yielding a match object for each match.
+    compile   Compile a pattern into a RegexObject.
+    purge     Clear the regular expression cache.
+    escape    Backslash all non-alphanumerics in a string.
+
+Some of the functions in this module takes flags as optional parameters:
+    A  ASCII       For string patterns, make \w, \W, \b, \B, \d, \D
+                   match the corresponding ASCII character categories
+                   (rather than the whole Unicode categories, which is the
+                   default).
+                   For bytes patterns, this flag is the only available
+                   behaviour and needn't be specified.
+    I  IGNORECASE  Perform case-insensitive matching.
+    L  LOCALE      Make \w, \W, \b, \B, dependent on the current locale.
+    M  MULTILINE   "^" matches the beginning of lines (after a newline)
+                   as well as the string.
+                   "$" matches the end of lines (before a newline) as well
+                   as the end of the string.
+    S  DOTALL      "." matches any character at all, including the newline.
+    X  VERBOSE     Ignore whitespace and comments for nicer looking RE's.
+    U  UNICODE     For compatibility only. Ignored for string patterns (it
+                   is the default), and forbidden for bytes patterns.
+
+This module also defines an exception 'error'.

+"""A generally useful event scheduler class.
+
+Each instance of this class manages its own queue.
+No multi-threading is implied; you are supposed to hack that
+yourself, or use a single instance per application.
+
+Each instance is parametrized with two functions, one that is
+supposed to return the current time, one that is supposed to
+implement a delay.  You can implement real-time scheduling by
+substituting time and sleep from built-in module time, or you can
+implement simulated time by writing your own functions.  This can
+also be used to integrate scheduling with STDWIN events; the delay
+function is allowed to modify the queue.  Time can be expressed as
+integers or floating point numbers, as long as it is consistent.
+
+Events are specified by tuples (time, priority, action, argument, kwargs).
+As in UNIX, lower priority numbers mean higher priority; in this
+way the queue can be maintained as a priority queue.  Execution of the
+event means calling the action function, passing it the argument
+sequence in "argument" (remember that in Python, multiple function
+arguments are be packed in a sequence) and keyword parameters in "kwargs".
+The action function may be an instance method so it
+has another way to reference private data (besides global variables).
+"""
+
+# XXX The timefunc and delayfunc should have been defined as methods
+# XXX so you can define new kinds of schedulers using subclassing
+# XXX instead of having to define a module or class just to hold

+        The current version supports all possible conversions between
+        "L", "RGB" and "CMYK." The **matrix** argument only supports "L"
+        and "RGB".
+
+        When translating a color image to black and white (mode "L"),
+        the library uses the ITU-R 601-2 luma transform::
+
+            L = R * 299/1000 + G * 587/1000 + B * 114/1000
+
+        The default method of converting a greyscale ("L") or "RGB"
+        image into a bilevel (mode "1") image uses Floyd-Steinberg
+        dither to approximate the original image luminosity levels. If
+        dither is NONE, all non-zero values are set to 255 (white). To
+        use other thresholds, use the :py:meth:`~PIL.Image.Image.point`
+        method.
+
+        :param mode: The requested mode.
+        :param matrix: An optional conversion matrix.  If given, this
+           should be 4- or 16-tuple containing floating point values.
+        :param dither: Dithering method, used when converting from
+           mode "RGB" to "P" or from "RGB" or "L" to "1".

+           to "P".  Available palettes are WEB or ADAPTIVE.
+        :param colors: Number of colors to use for the ADAPTIVE palette.

+
+    The pyCMS.py module provides a "clean" interface between Python/PIL and

+    pyCMSdll functions, as well as error-checking and making sure that all

+
+    While it is possible to call pyCMSdll functions directly, it's not highly

+                        Added try/except statements arount type() checks of
+                        potential CObjects... Python won't let you use type()
+                        on them, and raises a TypeError (stupid, if you ask
+                        me!)
+
+                        Added buildProofTransformFromOpenProfiles() function.
+                        Additional fixes in DLL, see DLL code for details.

+# 1996-08-13 fl   Added text support
+# 1998-06-28 fl   Handle I and F images
+# 1998-12-29 fl   Added arc; use arc primitive to draw ellipses
+# 1999-01-10 fl   Added shape stuff (experimental)
+# 1999-02-06 fl   Added bitmap support
+# 1999-02-11 fl   Changed all primitives to take options
+# 1999-02-20 fl   Fixed backwards compatibility
+# 2000-10-12 fl   Copy on write, when necessary
+# 2001-02-18 fl   Use default ink for bitmap/text also in fill mode
+# 2002-10-24 fl   Added support for CSS-style color strings
+# 2002-12-10 fl   Added experimental support for RGBA-on-RGB drawing
+# 2002-12-11 fl   Refactored low-level drawing API (work in progress)
+# 2004-08-26 fl   Made Draw() a factory function, added getdraw() support

+# PIL raster font management
+#
+# History:
+# 1996-08-07 fl   created (experimental)
+# 1997-08-25 fl   minor adjustments to handle fonts from pilfont 0.3
+# 1999-02-06 fl   rewrote most font management stuff in C
+# 1999-03-17 fl   take pth files into account in load_path (from Richard Jones)
+# 2001-02-17 fl   added freetype support
+# 2001-05-09 fl   added TransposedFont wrapper class
+# 2002-03-04 fl   make sure we have a "L" or "1" font
+# 2002-12-04 fl   skip non-directory entries in the system path
+# 2003-04-29 fl   add embedded default font
+# 2003-09-27 fl   added support for truetype charmap encodings
+#
+# Todo:
+# Adapt to PILFONT2 format (16-bit fonts, compressed, single file)

+JPEG quality settings equivalent to the Photoshop settings.
+
+More presets can be added to the presets dict if needed.
+
+Can be use when saving JPEG file.
+
+To apply the preset, specify::
+
+  quality="preset_name"
+
+To apply only the quantization table::
+
+  qtables="preset_name"
+
+To apply only the subsampling setting::
+
+  subsampling="preset_name"
+
+Example::
+
+  im.save("image_name.jpg", quality="web_high")
+
+
+Subsampling
+-----------
+
+Subsampling is the practice of encoding images by implementing less resolution
+for chroma information than for luma information.
+(ref.: http://en.wikipedia.org/wiki/Chroma_subsampling)
+
+Possible subsampling values are 0, 1 and 2 that correspond to 4:4:4, 4:2:2 and
+4:1:1 (or 4:2:0?).
+
+You can get the subsampling of a JPEG with the
+`JpegImagePlugin.get_subsampling(im)` function.
+
+
+Quantization tables
+-------------------
+
+They are values use by the DCT (Discrete cosine transform) to remove
+*unnecessary* information from the image (the lossy part of the compression).
+(ref.: http://en.wikipedia.org/wiki/Quantization_matrix#Quantization_matrices,
+http://en.wikipedia.org/wiki/JPEG#Quantization)
+
+You can get the quantization tables of a JPEG with::
+
+  im.quantization
+
+This will return a dict with a number of arrays. You can pass this dict directly
+as the qtables argument when saving a JPEG.
+
+The tables format between im.quantization and quantization in presets differ in
+3 ways:
+
+1. The base container of the preset is a list with sublists instead of dict.
+   dict[0] -> list[0], dict[1] -> list[1], ...
+2. Each table in a preset is a list instead of an array.
+3. The zigzag order is remove in the preset (needed by libjpeg >= 6a).
+
+You can convert the dict format to the preset format with the
+`JpegImagePlugin.convert_dict_qtables(dict_qtables)` function.

+OleFileIO_PL
+============
+
+[OleFileIO_PL](http://www.decalage.info/python/olefileio) is a Python module to parse and read [Microsoft OLE2 files (also called Structured Storage, Compound File Binary Format or Compound Document File Format)](http://en.wikipedia.org/wiki/Compound_File_Binary_Format), such as Microsoft Office documents, Image Composer and FlashPix files, Outlook messages, StickyNotes, several Microscopy file formats ...
+
+This is an improved version of the OleFileIO module from [PIL](http://www.pythonware.com/products/pil/index.htm), the excellent Python Imaging Library, created and maintained by Fredrik Lundh. The API is still compatible with PIL, but since 2005 I have improved the internal implementation significantly, with new features, bugfixes and a more robust design.
+
+As far as I know, this module is now the most complete and robust Python implementation to read MS OLE2 files, portable on several operating systems. (please tell me if you know other similar Python modules)
+
+OleFileIO_PL can be used as an independent module or with PIL. The goal is to have it integrated into [Pillow](http://python-pillow.github.io/), the friendly fork of PIL.
+
+OleFileIO\_PL is mostly meant for developers. If you are looking for tools to analyze OLE files or to extract data, then please also check [python-oletools](http://www.decalage.info/python/oletools), which are built upon OleFileIO_PL.

+
+How to use this module
+----------------------
+
+OleFileIO_PL can be used as an independent module or with PIL. The main functions and methods are explained below.
+
+For more information, see also the file **OleFileIO_PL.html**, sample code at the end of the module itself, and docstrings within the code.
+
+### About the structure of OLE files ###
+
+An OLE file can be seen as a mini file system or a Zip archive: It contains **streams** of data that look like files embedded within the OLE file. Each stream has a name. For example, the main stream of a MS Word document containing its text is named "WordDocument".
+
+An OLE file can also contain **storages**. A storage is a folder that contains streams or other storages. For example, a MS Word document with VBA macros has a storage called "Macros".
+
+Special streams can contain **properties**. A property is a specific value that can be used to store information such as the metadata of a document (title, author, creation date, etc). Property stream names usually start with the character '\x05'.
+
+For example, a typical MS Word document may look like this:
+
+	\x05DocumentSummaryInformation (stream)
+	\x05SummaryInformation (stream)
+	WordDocument (stream)
+	Macros (storage)
+		PROJECT (stream)
+		PROJECTwm (stream)
+		VBA (storage)
+			Module1 (stream)
+			ThisDocument (stream)
+			_VBA_PROJECT (stream)
+			dir (stream)
+	ObjectPool (storage)
+
+
+
+### Import OleFileIO_PL ###
+
+	:::python
+		import OleFileIO_PL
+
+As of version 0.30, the code has been changed to be compatible with Python 3.x. As a consequence, compatibility with Python 2.5 or older is not provided anymore. However, a copy of v0.26 is available as OleFileIO_PL2.py. If your application needs to be compatible with Python 2.5 or older, you may use the following code to load the old version when needed:
+
+	:::python
+		try:
+			import OleFileIO_PL
+		except:
+			import OleFileIO_PL2 as OleFileIO_PL
+
+If you think OleFileIO_PL should stay compatible with Python 2.5 or older, please [contact me](http://decalage.info/contact).
+
+
+### Test if a file is an OLE container ###
+
+Use isOleFile to check if the first bytes of the file contain the Magic for OLE files, before opening it. isOleFile returns True if it is an OLE file, False otherwise (new in v0.16).
+
+	:::python
+		assert OleFileIO_PL.isOleFile('myfile.doc')
+
+
+### Open an OLE file from disk ###
+
+Create an OleFileIO object with the file path as parameter:
+
+	:::python
+		ole = OleFileIO_PL.OleFileIO('myfile.doc')
+
+### Open an OLE file from a file-like object ###
+
+This is useful if the file is not on disk, e.g. already stored in a string or as a file-like object.
+
+	:::python
+		ole = OleFileIO_PL.OleFileIO(f)
+
+For example the code below reads a file into a string, then uses BytesIO to turn it into a file-like object.
+
+	:::python
+		data = open('myfile.doc', 'rb').read()
+		f = io.BytesIO(data) # or StringIO.StringIO for Python 2.x
+		ole = OleFileIO_PL.OleFileIO(f)
+
+### How to handle malformed OLE files ###
+
+By default, the parser is configured to be as robust and permissive as possible, allowing to parse most malformed OLE files. Only fatal errors will raise an exception. It is possible to tell the parser to be more strict in order to raise exceptions for files that do not fully conform to the OLE specifications, using the raise_defect option (new in v0.14):
+
+	:::python
+		ole = OleFileIO_PL.OleFileIO('myfile.doc', raise_defects=DEFECT_INCORRECT)
+
+When the parsing is done, the list of non-fatal issues detected is available as a list in the parsing_issues attribute of the OleFileIO object (new in 0.25):
+
+	:::python
+        print('Non-fatal issues raised during parsing:')
+        if ole.parsing_issues:
+            for exctype, msg in ole.parsing_issues:
+                print('- %s: %s' % (exctype.__name__, msg))
+        else:
+            print('None')
+
+
+### Syntax for stream and storage path ###
+
+Two different syntaxes are allowed for methods that need or return the path of streams and storages:
+
+1) Either a **list of strings** including all the storages from the root up to the stream/storage name. For example a stream called "WordDocument" at the root will have ['WordDocument'] as full path. A stream called "ThisDocument" located in the storage "Macros/VBA" will be ['Macros', 'VBA', 'ThisDocument']. This is the original syntax from PIL. While hard to read and not very convenient, this syntax works in all cases.
+
+2) Or a **single string with slashes** to separate storage and stream names (similar to the Unix path syntax). The previous examples would be 'WordDocument' and 'Macros/VBA/ThisDocument'. This syntax is easier, but may fail if a stream or storage name contains a slash. (new in v0.15)
+
+Both are case-insensitive.
+
+Switching between the two is easy:
+
+	:::python
+		slash_path = '/'.join(list_path)
+		list_path  = slash_path.split('/')
+
+
+### Get the list of streams ###
+
+listdir() returns a list of all the streams contained in the OLE file, including those stored in storages. Each stream is listed itself as a list, as described above.
+
+	:::python
+		print(ole.listdir())
+
+Sample result:
+
+	:::python
+		[['\x01CompObj'], ['\x05DocumentSummaryInformation'], ['\x05SummaryInformation']
+		, ['1Table'], ['Macros', 'PROJECT'], ['Macros', 'PROJECTwm'], ['Macros', 'VBA',
+		'Module1'], ['Macros', 'VBA', 'ThisDocument'], ['Macros', 'VBA', '_VBA_PROJECT']
+		, ['Macros', 'VBA', 'dir'], ['ObjectPool'], ['WordDocument']]
+
+As an option it is possible to choose if storages should also be listed, with or without streams (new in v0.26):
+
+	:::python
+		ole.listdir (streams=False, storages=True)
+
+
+### Test if known streams/storages exist: ###
+
+exists(path) checks if a given stream or storage exists in the OLE file (new in v0.16).
+
+	:::python
+		if ole.exists('worddocument'):
+		    print("This is a Word document.")
+		    if ole.exists('macros/vba'):
+		         print("This document seems to contain VBA macros.")
+
+
+### Read data from a stream ###
+
+openstream(path) opens a stream as a file-like object.
+
+The following example extracts the "Pictures" stream from a PPT file:
+
+	:::python
+	    pics = ole.openstream('Pictures')
+	    data = pics.read()
+
+
+### Get information about a stream/storage ###
+
+Several methods can provide the size, type and timestamps of a given stream/storage:
+
+get_size(path) returns the size of a stream in bytes (new in v0.16):
+
+	:::python
+		s = ole.get_size('WordDocument')
+
+get_type(path) returns the type of a stream/storage, as one of the following constants: STGTY\_STREAM for a stream, STGTY\_STORAGE for a storage, STGTY\_ROOT for the root entry, and False for a non existing path (new in v0.15).
+
+	:::python
+		t = ole.get_type('WordDocument')
+
+get\_ctime(path) and get\_mtime(path) return the creation and modification timestamps of a stream/storage, as a Python datetime object with UTC timezone. Please note that these timestamps are only present if the application that created the OLE file explicitly stored them, which is rarely the case. When not present, these methods return None (new in v0.26).
+
+	:::python
+		c = ole.get_ctime('WordDocument')
+		m = ole.get_mtime('WordDocument')
+
+The root storage is a special case: You can get its creation and modification timestamps using the OleFileIO.root attribute (new in v0.26):
+
+	:::python
+		c = ole.root.getctime()
+		m = ole.root.getmtime()
+
+### Extract metadata ###
+
+get_metadata() will check if standard property streams exist, parse all the properties they contain, and return an OleMetadata object with the found properties as attributes (new in v0.24).
+
+	:::python
+		meta = ole.get_metadata()
+		print('Author:', meta.author)
+		print('Title:', meta.title)
+		print('Creation date:', meta.create_time)
+		# print all metadata:
+		meta.dump()
+
+Available attributes include:
+
+    codepage, title, subject, author, keywords, comments, template,
+    last_saved_by, revision_number, total_edit_time, last_printed, create_time,
+    last_saved_time, num_pages, num_words, num_chars, thumbnail,
+    creating_application, security, codepage_doc, category, presentation_target,
+    bytes, lines, paragraphs, slides, notes, hidden_slides, mm_clips,
+    scale_crop, heading_pairs, titles_of_parts, manager, company, links_dirty,
+    chars_with_spaces, unused, shared_doc, link_base, hlinks, hlinks_changed,
+    version, dig_sig, content_type, content_status, language, doc_version
+
+See the source code of the OleMetadata class for more information.
+
+
+### Parse a property stream ###
+
+get\_properties(path) can be used to parse any property stream that is not handled by get\_metadata. It returns a dictionary indexed by integers. Each integer is the index of the property, pointing to its value. For example in the standard property stream '\x05SummaryInformation', the document title is property #2, and the subject is #3.
+
+	:::python
+		p = ole.getproperties('specialprops')
+
+By default as in the original PIL version, timestamp properties are converted into a number of seconds since Jan 1,1601. With the option convert\_time, you can obtain more convenient Python datetime objects (UTC timezone). If some time properties should not be converted (such as total editing time in '\x05SummaryInformation'), the list of indexes can be passed as no_conversion (new in v0.25):
+
+	:::python
+		p = ole.getproperties('specialprops', convert_time=True, no_conversion=[10])
+
+
+### Close the OLE file ###
+
+Unless your application is a simple script that terminates after processing an OLE file, do not forget to close each OleFileIO object after parsing to close the file on disk. (new in v0.22)
+
+	:::python
+		ole.close()
+
+### Use OleFileIO_PL as a script ###
+
+OleFileIO_PL can also be used as a script from the command-line to display the structure of an OLE file and its metadata, for example:
+
+	OleFileIO_PL.py myfile.doc
+
+You can use the option -c to check that all streams can be read fully, and -d to generate very verbose debugging information.
+
+## Real-life examples ##
+
+A real-life example: [using OleFileIO_PL for malware analysis and forensics](http://blog.gregback.net/2011/03/using-remnux-for-forensic-puzzle-6/).
+
+See also [this paper](https://computer-forensics.sans.org/community/papers/gcfa/grow-forensic-tools-taxonomy-python-libraries-helpful-forensic-analysis_6879) about python tools for forensics, which features OleFileIO_PL.
+
+About Python 2 and 3
+--------------------
+
+OleFileIO\_PL used to support only Python 2.x. As of version 0.30, the code has been changed to be compatible with Python 3.x. As a consequence, compatibility with Python 2.5 or older is not provided anymore. However, a copy of v0.26 is available as OleFileIO_PL2.py. See above the "import" section for a workaround.
+
+If you think OleFileIO_PL should stay compatible with Python 2.5 or older, please [contact me](http://decalage.info/contact).
+
+How to contribute
+-----------------
+
+The code is available in [a Mercurial repository on bitbucket](https://bitbucket.org/decalage/olefileio_pl). You may use it to submit enhancements or to report any issue.

+
+#-----------------------------------------------------------------------------
+# TODO (for version 1.0):
+# + isOleFile should accept file-like objects like open
+# + fix how all the methods handle unicode str and/or bytes as arguments
+# + add path attrib to _OleDirEntry, set it once and for all in init or
+#   append_kids (then listdir/_list can be simplified)
+# - TESTS with Linux, MacOSX, Python 1.5.2, various files, PIL, ...
+# - add underscore to each private method, to avoid their display in
+#   pydoc/epydoc documentation - Remove it for classes to be documented
+# - replace all raised exceptions with _raise_defect (at least in OleFileIO)
+# - merge code from _OleStream and OleFileIO.getsect to read sectors
+#   (maybe add a class for FAT and MiniFAT ?)
+# - add method to check all streams (follow sectors chains without storing all
+#   stream in memory, and report anomalies)
+# - use _OleDirectoryEntry.kids_dict to improve _find and _list ?
+# - fix Unicode names handling (find some way to stay compatible with Py1.5.2)
+#   => if possible avoid converting names to Latin-1
+# - review DIFAT code: fix handling of DIFSECT blocks in FAT (not stop)
+# - rewrite OleFileIO.getproperties
+# - improve docstrings to show more sample uses
+# - see also original notes and FIXME below
+# - remove all obsolete FIXMEs
+# - OleMetadata: fix version attrib according to
+#   http://msdn.microsoft.com/en-us/library/dd945671%28v=office.12%29.aspx
+
+# IDEAS:
+# - in OleFileIO._open and _OleStream, use size=None instead of 0x7FFFFFFF for
+#   streams with unknown size
+# - use arrays of int instead of long integers for FAT/MiniFAT, to improve
+#   performance and reduce memory usage ? (possible issue with values >2^31)
+# - provide tests with unittest (may need write support to create samples)
+# - move all debug code (and maybe dump methods) to a separate module, with
+#   a class which inherits OleFileIO ?
+# - fix docstrings to follow epydoc format
+# - add support for 4K sectors ?
+# - add support for big endian byte order ?
+# - create a simple OLE explorer with wxPython
+
+# FUTURE EVOLUTIONS to add write support:
+# 1) add ability to write a stream back on disk from BytesIO (same size, no
+#    change in FAT/MiniFAT).
+# 2) rename a stream/storage if it doesn't change the RB tree
+# 3) use rbtree module to update the red-black tree + any rename
+# 4) remove a stream/storage: free sectors in FAT/MiniFAT
+# 5) allocate new sectors in FAT/MiniFAT
+# 6) create new storage/stream

+# TIFF file handling
+#
+# TIFF is a flexible, if somewhat aged, image file format originally
+# defined by Aldus.  Although TIFF supports a wide variety of pixel
+# layouts and compression methods, the name doesn't really stand for
+# "thousands of incompatible file formats," it just feels that way.
+#
+# To read TIFF data from a stream, the stream must be seekable.  For
+# progressive decoding, make sure to use TIFF files where the tag
+# directory is placed first in the file.
+#
+# History:
+# 1995-09-01 fl   Created
+# 1996-05-04 fl   Handle JPEGTABLES tag
+# 1996-05-18 fl   Fixed COLORMAP support
+# 1997-01-05 fl   Fixed PREDICTOR support
+# 1997-08-27 fl   Added support for rational tags (from Perry Stoll)
+# 1998-01-10 fl   Fixed seek/tell (from Jan Blom)
+# 1998-07-15 fl   Use private names for internal variables
+# 1999-06-13 fl   Rewritten for PIL 1.0 (1.0)
+# 2000-10-11 fl   Additional fixes for Python 2.0 (1.1)
+# 2001-04-17 fl   Fixed rewind support (seek to frame 0) (1.2)
+# 2001-05-12 fl   Added write support for more tags (from Greg Couch) (1.3)
+# 2001-12-18 fl   Added workaround for broken Matrox library
+# 2002-01-18 fl   Don't mess up if photometric tag is missing (D. Alan Stewart)
+# 2003-05-19 fl   Check FILLORDER tag
+# 2003-09-26 fl   Added RGBa support
+# 2004-02-24 fl   Added DPI support; fixed rational write support
+# 2005-02-07 fl   Added workaround for broken Corel Draw 10 files
+# 2006-01-09 fl   Added support for float/double tags (from Russell Nelson)

+            *** Changes from release 1.1.6 to 1.1.7 ***
+        
+            This section may not be fully complete.  For changes since this file
+            was last updated, see the repository revision history:
+        
+              http://bitbucket.org/effbot/pil-2009-raclette/changesets/
+        
+            (1.1.7 final)
+        
+            + Set GIF loop info property to the number of iterations if a NETSCAPE
+              loop extension is present, instead of always setting it to 1 (from
+              Valentino Volonghi).
+        
+            (1.1.7c1 released)
+        
+            + Improved PNG compression (from Alexey Borzenkov).
+        
+            + Read interlaced PNG files (from Conrado Porto Lopes Gouvêa)
+        
+            + Added various TGA improvements from Alexey Borzenkov, including
+              support for specifying image orientation.
+        
+            + Bumped block threshold to 16 megabytes, made size estimation a bit
+              more accurate.  This speeds up allocation of large images.
+        
+            + Fixed rounding error in ImagingDrawWideLine.
+        
+              "gormish" writes: ImagingDrawWideLine() in Draw.c has a bug in every
+              version I've seen, which leads to different width lines depending on
+              the order of the points in the line. This is especially bad at some
+              angles where a 'width=2' line can completely disappear.
+        
+            + Added support for RGBA mode to the SGI module (based on code by
+              Karsten Hiddemann).
+        
+            + Handle repeated IPTC tags (adapted from a patch by Eric Bruning).
+        
+              Eric writes: According to the specification, some IPTC tags can be
+              repeated, e.g., tag 2:25 (keywords). PIL 1.1.6 only retained the last
+              instance of that tag. Below is a patch to store all tags. If there are
+              multiple tag instances, they are stored in a (python) list. Single tag
+              instances remain as strings.
+        
+            + Fixed potential crash in ImageFilter for small target images
+              (reported by Zac Burns and Daniel Fetchinson).
+        
+            + Use BMP instead of JPEG as temporary show format on Mac OS X.
+        
+            + Fixed putpixel/new for I;16 with colors > 255.
+        
+            + Added integer power support to ImagingMath.
+        
+            + Added limited support for I;16L mode (explicit little endian).
+        
+            + Moved WMF support into Image.core; enable WMF rendering by default
+              if renderer is available.
+        
+            + Mark the ARG plugin as obsolete.
+        
+            + Added version query mechanism to ImageCms and ImageFont, for
+              debugging.
+        
+            + Added (experimental) ImageCms function for fetching the ICC profile
+              for the current display (currently Windows only).
+        
+              Added HWND/HDC support to ImageCms.get_display_profile().
+        
+            + Added WMF renderer (Windows only).
+        
+            + Added ImagePointHandler and ImageTransformHandler mixins; made
+              ImageCmsTransform work with im.point.
+        
+            + Fixed potential endless loop in the XVThumbnail reader (from Nikolai
+              Ugelvik).
+        
+            + Added Kevin Cazabon's pyCMS package.
+        
+              The C code has been moved to _imagingcms.c, the Python interface
+              module is installed as PIL.ImageCMS.
+        
+              Added support for in-memory ICC profiles.
+        
+              Unified buildTransform and buildTransformFromOpenProfiles.
+        
+              The profile can now be either a filename, a profile object, or a
+              file-like object containing an in-memory profile.
+        
+              Additional fixes from Florian Böch:
+        
+                Very nice - it just needs LCMS flags support so we can use black
+                point compensation and softproofing :) See attached patches.  They
+                also fix a naming issue which could cause confusion - display
+                profile (ImageCms wording) actually means proof profile (lcms
+                wording), so I changed variable names and docstrings where
+                applicable. Patches are tested under Python 2.6.
+        
+            + Improved support for layer names in PSD files (from Sylvain Baubeau)
+        
+              Sylvain writes: I needed to be able to retrieve the names of the
+              layers in a PSD files. But PsdImagePlugin.py didn't do the job so I
+              wrote this very small patch.
+        
+            + Improved RGBA support for ImageTk for 8.4 and newer (from Con
+              Radchenko).
+        
+              This replaces the slow run-length based encoding model with true
+              compositing at the Tk level.
+        
+            + Added support for 16- and 32-bit images to McIdas loader.
+        
+              Based on file samples and stand-alone reader code provided by Craig
+              Swank.
+        
+            + Added ImagePalette support to putpalette.
+        
+            + Fixed problem with incremental parsing of PNG files.
+        
+            + Make selftest.py report non-zero status on failure (from Mark
+              Sienkiewicz)
+        
+            + Add big endian save support and multipage infrastructure to the TIFF
+              writer (from Sebastian Haase).
+        
+            + Handle files with GPS IFD but no basic EXIF IFD (reported by Kurt
+              Schwehr).
+        
+            + Added zTXT support (from Andrew Kuchling via Lowell Alleman).
+        
+            + Fixed potential infinite loop bug in ImageFont (from Guilherme Polo).
+        
+            + Added sample ICC profiles (from Kevin Cazabon)
+        
+            + Fixed array interface for I, F, and RGBA/RGBX images.
+        
+            + Added Chroma subsampling support for JPEG (from Justin Huff).
+        
+              Justin writes: Attached is a patch (against PIL 1.1.6) to provide
+              control over the chroma subsampling done by the JPEG encoder.  This
+              is often useful for reducing compression artifacts around edges of
+              clipart and text.
+        
+            + Added USM/Gaussian Blur code from Kevin Cazabon.
+        
+            + Fixed bug w. uninitialized image data when cropping outside the
+              source image.
+        
+            + Use ImageShow to implement the Image.show method.
+        
+              Most notably, this picks the 'display' utility when available.  It
+              also allows application code to register new display utilities via
+              the ImageShow registry.
+        
+            + Release the GIL in the PNG compressor (from Michael van Tellingen).
+        
+            + Revised JPEG CMYK handling.
+        
+              Always assume Adobe behaviour, both when reading and writing (based on
+              a patch by Kevin Cazabon, and test data by Tim V. and Charlie Clark, and
+              additional debugging by Michael van Tellingen).
+        
+            + Support for preserving ICC profiles (by Florian Böch via Tim Hatch).
+        
+              Florian writes:
+        
+              It's a beta, so still needs some testing, but should allow you to:
+              - retain embedded ICC profiles when saving from/to JPEG, PNG, TIFF.
+                 Existing code doesn't need to be changed.
+              - access embedded profiles in JPEG, PNG, PSD, TIFF.
+        
+              It also includes patches for TIFF to retain IPTC, Photoshop and XMP
+              metadata when saving as TIFF again, read/write TIFF resolution
+              information correctly, and to correct inverted CMYK JPEG files.
+        
+            + Fixed potential memory leak in median cut quantizer (from Evgeny Salmin).
+        
+            + Fixed OverflowError when reading upside-down BMP images.
+        
+            + Added resolution save option for PDF files.
+        
+              Andreas Kostyrka writes: I've included a patched PdfImagePlugin.py
+              based on 1.1.6 as included in Ubuntu, that supports a "resolution"
+              save option. Not great, but it makes the PDF saving more useful by
+              allowing PDFs that are not exactly 72dpi.
+        
+            + Look for Tcl/Tk include files in version-specific include directory
+              (from Encolpe Degoute).
+        
+            + Fixed grayscale rounding error in ImageColor.getcolor (from Tim
+              Hatch).
+        
+            + Fixed calculation of mean value in ImageEnhance.Contrast (reported
+              by "roop" and Scott David Daniels).
+        
+            + Fixed truetype positioning when first character has a negative left
+              bearing (from Ned Batchelder):
+        
+              Ned writes: In PIL 1.1.6, ImageDraw.text will position the string
+              incorrectly if the first character has a negative left bearing.  To
+              see the problem, show a string like "///" in an italic font.  The
+              first slash will be clipped at the left, and the string will be
+              mis-positioned.
+        
+            + Fixed resolution unit bug in tiff reader/writer (based on code by
+              Florian Höch, Gary Bloom, and others).
+        
+            + Added simple transparency support for RGB images (reported by
+              Sebastian Spaeth).
+        
+            + Added support for Unicode filenames in ImageFont.truetype (from Donn
+              Ingle).
+        
+            + Fixed potential crash in ImageFont.getname method (from Donn Ingle).
+        
+            + Fixed encoding issue in PIL/WalImageFile (from Santiago M. Mola).
+        
+            *** Changes from release 1.1.5 to 1.1.6 ***
+        
+            (1.1.6 released)
+        
+            + Fixed some 64-bit compatibility warnings for Python 2.5.
+        
+            + Added threading support for the Sane driver (from Abel Deuring).
+        
+            (1.1.6b2 released)
+        
+            + Added experimental "floodfill" function to the ImageDraw module
+              (based on code by Eric Raymond).
+        
+            + The default arguments for "frombuffer" doesn't match "fromstring"
+              and the documentation; this is a bug, and will most likely be fixed
+              in a future version.  In this release, PIL prints a warning message
+              instead.  To silence the warning, change any calls of the form
+              "frombuffer(mode, size, data)" to
+        
+                  frombuffer(mode, size, data, "raw", mode, 0, 1)
+        
+            + Added "fromarray" function, which takes an object implementing the
+              NumPy array interface and creates a PIL Image from it. (from Travis
+              Oliphant).
+        
+            + Added NumPy array interface support (__array_interface__) to the
+              Image class (based on code by Travis Oliphant).
+        
+              This allows you to easily convert between PIL image memories and
+              NumPy arrays:
+        
+                import numpy, Image
+        
+                im = Image.open('lena.jpg')
+        
+                a = numpy.asarray(im) # a is readonly
+        
+                im = Image.fromarray(a)
+        
+            + Fixed CMYK polarity for JPEG images, by treating all images as
+              "Adobe CMYK" images. (thanks to Cesare Leonardi and Kevin Cazabon
+              for samples, debugging, and patches).
+        
+            (1.1.6b1 released)
+        
+            + Added 'expand' option to the Image 'rotate' method.  If true, the
+              output image is made large enough to hold the entire rotated image.
+        
+            + Changed the ImageDraw 'line' method to always draw the last pixel in
+              a polyline, independent of line angle.
+        
+            + Fixed bearing calculation and clipping in the ImageFont truetype
+              renderer; this could lead to clipped text, or crashes in the low-
+              level _imagingft module.  (based on input from Adam Twardoch and
+              others).
+        
+            + Added ImageQt wrapper module, for converting PIL Image objects to
+              QImage objects in an efficient way.
+        
+            + Fixed 'getmodebands' to return the number of bands also for "PA"
+              and "LA" modes.  Added 'getmodebandnames' helper that return the
+              band names.
+        
+            (1.1.6a2 released)
+        
+            + Added float/double support to the TIFF loader (from Russell
+              Nelson).
+        
+            + Fixed broken use of realloc() in path.c (from Jan Matejek)
+        
+            + Added save support for Spider images (from William Baxter).
+        
+            + Fixed broken 'paste' and 'resize' operations in pildriver
+              (from Bill Janssen).
+        
+            + Added support for duplex scanning to the Sane interface (Abel
+              Deuring).
+        
+            (1.1.6a1 released)
+        
+            + Fixed a memory leak in "convert(mode)", when converting from
+              L to P.
+        
+            + Added pixel access object.  The "load" method now returns a
+              access object that can be used to directly get and set pixel
+              values, using ordinary [x, y] notation:
+        
+                pixel = im.load()
+                v = pixel[x, y]
+                pixel[x, y] = v
+        
+              If you're accessing more than a few pixels, this is a lot
+              faster than using getpixel/putpixel.
+        
+            + Fixed building on Cygwin (from Miki Tebeka).
+        
+            + Fixed "point(callable)" on unloaded images (reported by HÃ¥kan
+              Karlsson).
+        
+            + Fixed size bug in ImageWin.ImageWindow constructor (from Victor
+              Reijs)
+        
+            + Fixed ImageMath float() and int() operations for Python 2.4
+              (reported by Don Rozenberg).
+        
+            + Fixed "RuntimeError: encoder error -8 in tostring" problem for
+              wide "RGB", "I", and "F" images.
+        
+            + Fixed line width calculation.
+        
+            (1.1.6a0 released)
+        
+            + Fixed byte order issue in Image.paste(ink) (from Ka-Ping Yee).
+        
+            + Fixed off-by-0.5 errors in the ANTIALIAS code (based on input
+              from Douglas Bagnall).
+        
+            + Added buffer interface support to the Path constructor.  If
+              a buffer is provided, it is assumed to contain a flat array
+              of float coordinates (e.g. array.array('f', seq)).
+        
+            + Added new ImageMath module.
+        
+            + Fixed ImageOps.equalize when used with a small number of distinct
+              values (reported by David Kirtley).
+        
+            + Fixed potential integer division in PSDraw.image (from Eric Etheridge).
+        
+            *** Changes from release 1.1 to 1.1.5 ***
+        
+            (1.1.5c2 and 1.1.5 final released)
+        
+            + Added experimental PERSPECTIVE transform method (from Jeff Breiden-
+              bach).
+        
+            (1.1.5c1 released)
+        
+            + Make sure "thumbnail" never generates zero-wide or zero-high images
+              (reported by Gene Skonicki)
+        
+            + Fixed a "getcolors" bug that could result in a zero count for some
+              colors (reported by Richard Oudkerk).
+        
+            + Changed default "convert" palette to avoid "rounding errors" when
+              round-tripping white source pixels (reported by Henryk Gerlach and
+              Jeff Epler).
+        
+            (1.1.5b3 released)
+        
+            + Don't crash in "quantize" method if the number of colors requested
+              is larger than 256.  This release raises a ValueError exception;
+              future versions may return a mode "RGB" image instead (reported
+              by Richard Oudkerk).
+        
+            + Added WBMP read/write support (based on code by Duncan Booth).
+        
+            (1.1.5b2 released)
+        
+            + Added DPI read/write support to the PNG codec.  The decoder sets
+              the info["dpi"] attribute for PNG files with appropriate resolution
+              settings.  The encoder uses the "dpi" option (based on code by Niki
+              Spahiev).
+        
+            + Added limited support for "point" mappings from mode "I" to mode "L".
+              Only 16-bit values are supported (other values are clipped), the lookup
+              table must contain exactly 65536 entries, and the mode argument must be
+              set to "L".
+        
+            + Added support for Mac OS X icns files (based on code by Bob Ippolito).
+        
+            + Added "ModeFilter" support to the ImageFilter module.
+        
+            + Added support for Spider images (from William Baxter).  See the
+              comments in PIL/SpiderImagePlugin.py for more information on this
+              format.
+        
+            (1.1.5b1 released)
+        
+            + Added new Sane release (from Ralph Heinkel).  See the Sane/README
+              and Sane/CHANGES files for more information.
+        
+            + Added experimental PngInfo chunk container to the PngImageFile
+              module.  This can be used to add arbitrary chunks to a PNG file.
+              Create a PngInfo instance, use "add" or "add_text" to add chunks,
+              and pass the instance as the "pnginfo" option when saving the
+              file.
+        
+            + Added "getpalette" method.  This returns the palette as a list,
+              or None if the image has no palette.  To modify the palette, use
+              "getpalette" to fetch the current palette, modify the list, and
+              put it back using "putpalette".
+        
+            + Added optional flattening to the ImagePath "tolist" method.
+              tolist() or tolist(0) returns a list of 2-tuples, as before.
+              tolist(1) returns a flattened list instead.
+        
+            (1.1.5a5 released)
+        
+            + Fixed BILINEAR/BICUBIC/ANTIALIAS filtering for mode "LA".
+        
+            + Added "getcolors()" method.  This is similar to the existing histo-
+              gram method, but looks at color values instead of individual layers,
+              and returns an unsorted list of (count, color) tuples.
+        
+              By default, the method returns None if finds more than 256 colors.
+              If you need to look for more colors, you can pass in a limit (this
+              is used to allocate internal tables, so you probably don't want to
+              pass in too large values).
+        
+            + Build improvements: Fixed building under AIX, improved detection of
+              FreeType2 and Mac OS X framework libraries, and more.  Many thanks
+              to everyone who helped test the new "setup.py" script!
+        
+            (1.1.5a4 released)
+        
+            + The "save" method now looks for a file format driver before
+              creating the file.
+        
+            + Don't use antialiased truetype fonts when drawing in mode "P", "I",
+              and "F" images.
+        
+            + Rewrote the "setup.py" file.  The new version scans for available
+              support libraries, and configures both the libImaging core library
+              and the bindings in one step.
+        
+              To use specific versions of the libraries, edit the ROOT variables
+              in the setup.py file.
+        
+            + Removed threaded "show" viewer; use the old "show" implementation
+              instead (Windows).
+        
+            + Added deprecation warnings to Image.offset, ImageDraw.setink, and
+              ImageDraw.setfill.
+        
+            + Added width option to ImageDraw.line().  The current implementation
+              works best for straight lines; it does not support line joins, so
+              polylines won't look good.
+        
+            + ImageDraw.Draw is now a factory function instead of a class.  If
+              you need to create custom draw classes, inherit from the ImageDraw
+              class.    All other code should use the factory function.
+        
+            + Fixed loading of certain PCX files (problem reported by Greg
+              Hamilton, who also provided samples).
+        
+            + Changed _imagingft.c to require FreeType 2.1 or newer.  The
+              module can still be built with earlier versions; see comments
+              in _imagingft.c for details.
+        
+            (1.1.5a3 released)
+        
+            + Added 'getim' method, which returns a PyCObject wrapping an
+              Imaging pointer.  The description string is set to IMAGING_MAGIC.
+              See Imaging.h for pointer and string declarations.
+        
+            + Fixed reading of TIFF JPEG images (problem reported by Ulrik
+              Svensson).
+        
+            + Made ImageColor work under Python 1.5.2
+        
+            + Fixed division by zero "equalize" on very small images (from
+              Douglas Bagnall).
+        
+            (1.1.5a2 released)
+        
+            + The "paste" method now supports the alternative "paste(im, mask)"
+              syntax (in this case, the box defaults to im's bounding box).
+        
+            + The "ImageFile.Parser" class now works also for PNG files with
+              more than one IDAT block.
+        
+            + Added DPI read/write to the TIFF codec, and fixed writing of
+              rational values.  The decoder sets the info["dpi"] attribute
+              for TIFF files with appropriate resolution settings.  The
+              encoder uses the "dpi" option.
+        
+            + Disable interlacing for small (or narrow) GIF images, to
+              work around what appears to be a hard-to-find bug in PIL's
+              GIF encoder.
+        
+            + Fixed writing of mode "P" PDF images.  Made mode "1" PDF
+              images smaller.
+        
+            + Made the XBM reader a bit more robust; the file may now start
+              with a few whitespace characters.
+        
+            + Added support for enhanced metafiles to the WMF driver.  The
+              separate PILWMF kit lets you render both placeable WMF files
+              and EMF files as raster images.  See
+        
+                  http://effbot.org/downloads#pilwmf
+        
+            (1.1.5a1 released)
+        
+            + Replaced broken WMF driver with a WMF stub plugin (see below).
+        
+            + Fixed writing of mode "1", "L", and "CMYK" PDF images (based on
+              input from Nicholas Riley and others).
+        
+            + Fixed adaptive palette conversion for zero-width or zero-height
+              images (from Chris Cogdon)
+        
+            + Fixed reading of PNG images from QuickTime 6 (from Paul Pharr)
+        
+            + Added support for StubImageFile plugins, including stub plugins
+              for BUFR, FITS, GRIB, and HDF5 files.  A stub plugin can identify
+              a given file format, but relies on application code to open and
+              save files in that format.
+        
+            + Added optional "encoding" argument to the ImageFont.truetype
+              factory.  This argument can be used to specify non-Unicode character
+              maps for fonts that support that.  For example, to draw text using
+              the Microsoft Symbol font, use:
+        
+                  font = ImageFont.truetype("symbol.ttf", 16, encoding="symb")
+                  draw.text((0, 0), unichr(0xF000 + 0xAA))
+        
+              (note that the symbol font uses characters in the 0xF000-0xF0FF
+               range)
+        
+              Common encodings are "unic" (Unicode), "symb" (Microsoft Symbol),
+              "ADOB" (Adobe Standard), "ADBE" (Adobe Expert), and "armn" (Apple
+              Roman).  See the FreeType documentation for more information.
+        
+            + Made "putalpha" a bit more robust; you can now attach an alpha
+              layer to a plain "L" or "RGB" image, and you can also specify
+              constant alphas instead of alpha layers (using integers or colour
+              names).
+        
+            + Added experimental "LA" mode support.
+        
+              An "LA" image is an "L" image with an attached transparency layer.
+              Note that support for "LA" is not complete; some operations may
+              fail or produce unexpected results.
+        
+            + Added "RankFilter", "MinFilter", "MedianFilter", and "MaxFilter"
+              classes to the ImageFilter module.
+        
+            + Improved support for applications using multiple threads; PIL
+              now releases the global interpreter lock for many CPU-intensive
+              operations (based on work by Kevin Cazabon).
+        
+            + Ignore Unicode characters in the PCF loader (from Andres Polit)
+        
+            + Fixed typo in OleFileIO.loadfat, which could affect loading of
+              FlashPix and Image Composer images (Daniel Haertle)
+        
+            + Fixed building on platforms that have Freetype but don't have
+              Tcl/Tk (Jack Jansen, Luciano Nocera, Piet van Oostrum and others)
+        
+            + Added EXIF GPSInfo read support for JPEG files.  To extract
+              GPSInfo information, open the file, extract the exif dictionary,
+              and check for the key 0x8825 (GPSInfo).  If present, it contains
+              a dictionary mapping GPS keys to GPS values.  For a list of keys,
+              see the EXIF specification.
+        
+              The "ExifTags" module contains a GPSTAGS dictionary mapping GPS
+              tags to tag names.
+        
+            + Added DPI read support to the PCX and DCX codecs (info["dpi"]).
+        
+            + The "show" methods now uses a built-in image viewer on Windows.
+              This viewer creates an instance of the ImageWindow class (see
+              below) and keeps it running in a separate thread.  NOTE: This
+              was disabled in 1.1.5a4.
+        
+            + Added experimental "Window" and "ImageWindow" classes to the
+              ImageWin module.  These classes allow you to create a WCK-style
+              toplevel window, and use it to display raster data.
+        
+            + Fixed some Python 1.5.2 issues (to build under 1.5.2, use the
+              Makefile.pre.in/Setup.in approach)
+        
+            + Added support for the TIFF FillOrder tag.  PIL can read mode "1",
+              "L", "P" and "RGB" images with non-standard FillOrder (based on
+              input from Jeff Breidenbach).
+        
+            (1.1.4 final released)
+        
+            + Fixed ImageTk build problem on Unix.
+        
+            (1.1.4b2 released)
+        
+            + Improved building on Mac OS X (from Jack Jansen).
+        
+            + Improved building on Windows with MinGW (from Klamer Shutte).
+        
+            + If no font is specified, ImageDraw now uses the embedded default
+              font.  Use the "load" or "truetype" methods to load a real font.
+        
+            + Added embedded default font to the ImageFont module (currently
+              an 8-pixel Courier font, taken from the X window distribution).
+        
+            (1.1.4b1 released)
+        
+            + Added experimental EXIF support for JPEG files.  To extract EXIF
+              information from a JPEG file, open the file as usual, and call the
+              "_getexif" method.  If successful, this method returns a dictionary
+              mapping EXIF TIFF tags to values.  If the file does not contain EXIF
+              data, the "_getexif" method returns None.
+        
+              The "ExifTags" module contains a dictionary mapping tags to tag
+              names.
+        
+              This interface will most likely change in future versions.
+        
+            + Fixed a bug when using the "transparency" option with the GIF
+              writer.
+        
+            + Added limited support for "bitfield compression" in BMP files
+              and DIB buffers, for 15-bit, 16-bit, and 32-bit images.  This
+              also fixes a problem with ImageGrab module when copying screen-
+              dumps from the clipboard on 15/16/32-bit displays.
+        
+            + Added experimental WAL (Quake 2 textures) loader.  To use this
+              loader, import WalImageFile and call the "open" method in that
+              module.
+        
+            (1.1.4a4 released)
+        
+            + Added updated SANE driver (Andrew Kuchling, Abel Deuring)
+        
+            + Use Python's "mmap" module on non-Windows platforms to read some
+              uncompressed formats using memory mapping.  Also added a "frombuffer"
+              function that allows you to access the contents of an existing string
+              or buffer object as if it were an image object.
+        
+            + Fixed a memory leak that could appear when processing mode "P"
+              images (from Pier Paolo Glave)
+        
+            + Ignore Unicode characters in the BDF loader (from Graham Dumpleton)
+        
+            (1.1.4a3 released; windows only)
+        
+            + Added experimental RGBA-on-RGB drawing support.  To use RGBA
+              colours on an RGB image, pass "RGBA" as the second string to
+              the ImageDraw.Draw constructor.
+        
+            + Added support for non-ASCII strings (Latin-1) and Unicode
+              to the truetype font renderer.
+        
+            + The ImageWin "Dib" object can now be constructed directly from
+              an image object.
+        
+            + The ImageWin module now allows you use window handles as well
+              as device contexts.  To use a window handle, wrap the handle in
+              an ImageWin.HWND object, and pass in this object instead of the
+              device context.
+        
+            (1.1.4a2 released)
+        
+            + Improved support for 16-bit unsigned integer images (mode "I;16").
+              This includes TIFF reader support, and support for "getextrema"
+              and "point" (from Klamer Shutte).
+        
+            + Made the BdfFontFile reader a bit more robust (from Kevin Cazabon
+              and Dmitry Vasiliev)
+        
+            + Changed TIFF writer to always write Compression tag, even when
+              using the default compression (from Greg Couch).
+        
+            + Added "show" support for Mac OS X (from Dan Wolfe).
+        
+            + Added clipboard support to the "ImageGrab" module (Windows only).
+              The "grabclipboard" function returns an Image object, a list of
+              filenames (not in 1.1.4), or None if neither was found.
+        
+            (1.1.4a1 released)
+        
+            + Improved support for drawing RGB data in palette images.  You can
+              now use RGB tuples or colour names (see below) when drawing in a
+              mode "P" image.  The drawing layer automatically assigns color
+              indexes, as long as you don't use more than 256 unique colours.
+        
+            + Moved self test from MiniTest/test.py to ./selftest.py.
+        
+            + Added support for CSS3-style color strings to most places that
+              accept colour codes/tuples.  This includes the "ImageDraw" module,
+              the Image "new" function, and the Image "paste" method.
+        
+              Colour strings can use one of the following formats: "#f00",
+              "#ff0000", "rgb(255,0,0)", "rgb(100%,0%,0%)", "hsl(0, 100%, 50%)",
+              or "red" (most X11-style colour names are supported).  See the
+              documentation for the "ImageColor" module for more information.
+        
+            + Fixed DCX decoder (based on input from Larry Bates)
+        
+            + Added "IptcImagePlugin.getiptcinfo" helper to extract IPTC/NAA
+              newsphoto properties from JPEG, TIFF, or IPTC files.
+        
+            + Support for TrueType/OpenType fonts has been added to
+              the standard distribution.  You need the freetype 2.0
+              library.
+        
+            + Made the PCX reader a bit more robust when reading 2-bit
+              and 4-bit PCX images with odd image sizes.
+        
+            + Added "Kernel" class to the ImageFilter module.  This class
+              allows you to filter images with user-defined 3x3 and 5x5
+              convolution kernels.
+        
+            + Added "putdata" support for mode "I", "F" and "RGB".
+        
+            + The GIF writer now supports the transparency option (from
+              Denis Benoit).
+        
+            + A HTML version of the module documentation is now shipped
+              with the source code distribution.  You'll find the files in
+              the Doc subdirectory.
+        
+            + Added support for Palm pixmaps (from Bill Janssen).  This
+              change was listed for 1.1.3, but the "PalmImagePlugin" driver
+              didn't make it into the distribution.
+        
+            + Improved decoder error messages.
+        
+            (1.1.3 final released)
+        
+            + Made setup.py look for old versions of zlib.  For some back-
+              ground, see: http://www.gzip.org/zlib/advisory-2002-03-11.txt
+        
+            (1.1.3c2 released)
+        
+            + Added setup.py file (tested on Unix and Windows).  You still
+              need to build libImaging/imaging.lib in the traditional way,
+              but the setup.py script takes care of the rest.
+        
+              The old Setup.in/Makefile.pre.in build method is still
+              supported.
+        
+            + Fixed segmentation violation in ANTIALIAS filter (an internal
+              buffer wasn't properly allocated).
+        
+            (1.1.3c1 released)
+        
+            + Added ANTIALIAS downsampling filter for high-quality "resize"
+              and "thumbnail" operations.  Also added filter option to the
+              "thumbnail" operation; the default value is NEAREST, but this
+              will most likely change in future versions.
+        
+            + Fixed plugin loader to be more robust if the __file__
+              variable isn't set.
+        
+            + Added seek/tell support (for layers) to the PhotoShop
+              loader.  Layer 0 is the main image.
+        
+            + Added new (but experimental) "ImageOps" module, which provides
+              shortcuts for commonly used operations on entire images.
+        
+            + Don't mess up when loading PNG images if the decoder leaves
+              data in the output buffer.  This could cause internal errors
+              on some PNG images, with some versions of ZLIB. (Bug report
+              and patch provided by Bernhard Herzog.)
+        
+            + Don't mess up on Unicode filenames.
+        
+            + Don't mess up when drawing on big endian platforms.
+        
+            + Made the TIFF loader a bit more robust; it can now read some
+              more slightly broken TIFF files (based on input from Ted Wright,
+              Bob Klimek, and D. Alan Stewart)
+        
+            + Added OS/2 EMX build files (from Andrew MacIntyre)
+        
+            + Change "ImageFont" to reject image files if they don't have the
+              right mode.  Older versions could leak memory for "P" images.
+              (Bug reported by Markus Gritsch).
+        
+            + Renamed some internal functions to avoid potential build
+              problem on Mac OS X.
+        
+            + Added DL_EXPORT where relevant (for Cygwin, based on input
+              from Robert Yodlowski)
+        
+            + (re)moved bogus __init__ call in BdfFontFile (bug spotted
+              by Fred Clare)
+        
+            + Added "ImageGrab" support (Windows only)
+        
+            + Added support for XBM hotspots (based on code contributed by
+              Bernhard Herzog).
+        
+            + Added write support for more TIFF tags, namely the Artist,
+              Copyright, DateTime, ResolutionUnit, Software, XResolution and
+              YResolution tags (from Greg Couch)
+        
+            + Added TransposedFont wrapper to ImageFont module
+        
+            + Added "optimize" flag to GIF encoder.  If optimize is present
+              and non-zero, PIL will work harder to create a small file.
+        
+            + Raise "EOFError" (not IndexError) when reading beyond the
+              end of a TIFF sequence.
+        
+            + Support rewind ("seek(0)") for GIF and TIFF sequences.
+        
+            + Load grayscale GIF images as mode "L"
+        
+            + Added DPI read/write support to the JPEG codec.  The decoder
+              sets the info["dpi"] attribute for JPEG files with JFIF dpi
+              settings.  The encoder uses the "dpi" option:
+        
+                  im = Image.open("file.jpg")
+                  dpi = im.info["dpi"] # raises KeyError if DPI not known
+                  im.save("out.jpg", dpi=dpi)
+        
+              Note that PIL doesn't always preserve the "info" attribute
+              for normal image operations.
+        
+            (1.1.2c1 and 1.1.2 final released)
+        
+            + Adapted to Python 2.1.  Among other things, all uses of the
+              "regex" module has been repleased with "re".
+        
+            + Fixed attribute error when reading large PNG files (this bug
+              was introduced in maintenance code released after the 1.1.1
+              release)
+        
+            + Ignore non-string objects in sys.path
+        
+            + Fixed Image.transform(EXTENT) for negative xoffsets
+        
+            + Fixed loading of image plugins if PIL is installed as a package.
+              (The plugin loader now always looks in the directory where the
+              Image.py module itself is found, even if that directory isn't on
+              the standard search path)
+        
+            + The Png plugin has been added to the list of preloaded standard
+              formats
+        
+            + Fixed bitmap/text drawing in fill mode.
+        
+            + Fixed "getextrema" to work also for multiband images.
+        
+            + Added transparency support for L and P images to the PNG codec.
+        
+            + Improved support for read-only images.  The "load" method now
+              sets the "readonly" attribute for memory-mapped images.  Operations
+              that modifies an image in place (such as "paste" and drawing operations)
+              creates an in-memory copy of the image, if necessary.  (before this
+              change, any attempt to modify a memory-mapped image resulted in a
+              core dump...)
+        
+            + Added special cases for lists everywhere PIL expects a sequence.
+              This should speed up things like "putdata" and drawing operations.
+        
+            + The Image.offset method is deprecated.  Use the ImageChops.offset
+              function instead.
+        
+            + Changed ImageChops operators to copy palette and info dictionary
+              from the first image argument.
+        
+            (1.1.1 released)
+        
+            + Additional fixes for Python 1.6/2.0, including TIFF "save" bug.
+        
+            + Changed "init" to properly load plugins when PIL is used as a
+              package.
+        
+            + Fixed broken "show" method (on Unix)
+        
+            *** Changes from release 1.0 to 1.1 ***
+        
+            + Adapted to Python 1.6 ("append" and other method changes)
+        
+            + Fixed Image.paste when pasting with solid colour and matte
+              layers ("L" or "RGBA" masks) (bug reported by Robert Kern)
+        
+            + To make it easier to distribute prebuilt versions of PIL,
+              the tkinit binding stuff has been moved to a separate
+              extension module, named "_imagingtk".
+        
+            *** Changes from release 0.3b2 to 1.0 final ***
+        
+            + If there's no 16-bit integer (like on a Cray T3E), set
+              INT16 to the smallest integer available.  Most of the
+              library works just fine anyway (from Bill Crutchfield)
+        
+            + Tweaks to make drawing work on big-endian platforms.
+        
+            (1.0c2 released)
+        
+            + If PIL is built with the WITH_TKINTER flag, ImageTk can
+              automatically hook into a standard Tkinter build.  You
+              no longer need to build your own Tkinter to use the
+              ImageTk module.
+        
+              The old way still works, though.  For more information,
+              see Tk/install.txt.
+        
+            + Some tweaks to ImageTk to support multiple Tk interpreters
+              (from Greg Couch).
+        
+            + ImageFont "load_path" now scans directory mentioned in .pth
+              files (from Richard Jones).
+        
+            (1.0c1 released)
+        
+            + The TIFF plugin has been rewritten.  The new plugin fully
+              supports all major PIL image modes (including F and I).
+        
+            + The ImageFile module now includes a Parser class, which can
+              be used to incrementally decode an image file (while down-
+              loading it from the net, for example).  See the handbook for
+              details.
+        
+            + "show" now converts non-standard modes to "L" or "RGB" (as
+              appropriate), rather than writing weird things to disk for
+              "xv" to choke upon. (bug reported by Les Schaffer).
+        
+            (1.0b2 released)
+        
+            + Major speedups for rotate, transform(EXTENT), and transform(AFFINE)
+              when using nearest neighbour resampling.
+        
+            + Modified ImageDraw to be compatible with the Arrow graphics
+              interface.  See the handbook for details.
+        
+            + PIL now automatically loads file codecs when used as a package
+              (from The Dragon De Monsyne).  Also included an __init__.py file
+              in the standard distribution.
+        
+            + The GIF encoder has been modified to produce much smaller files.
+        
+              PIL now uses a run-length encoding method to encode GIF files.
+              On a random selection of GIF images grabbed from the web, this
+              version makes the images about twice as large as the original
+              LZW files, where the earlier version made them over 5 times
+              larger.  YMMV, of course.
+        
+            + Added PCX write support (works with "1", "P", "L", and "RGB")
+        
+            + Added "bitmap" and "textsize" methods to ImageDraw.
+        
+            + Improved font rendering code.  Fixed a bug or two, and moved
+              most of the time critical stuff to C.
+        
+            + Removed "bdf2pil.py".  Use "pilfont.py" instead!
+        
+            + Improved 16-bit support (still experimental, though).
+        
+              The following methods now support "I;16" and "I;16B" images:
+              "getpixel", "copy", "convert" (to and from mode "I"), "resize",
+              "rotate", and "transform" with nearest neighbour filters, and
+              "save" using the IM format.  The "new" and "open" functions
+              also work as expected.  On Windows, 16-bit files are memory
+              mapped.
+        
+              NOTE: ALL other operations are still UNDEFINED on 16-bit images.
+        
+            + The "paste" method now supports constant sources.
+        
+              Just pass a colour value (a number or a tuple, depending on
+              the target image mode) instead of the source image.
+        
+              This was in fact implemented in an inefficient way in
+              earlier versions (the "paste" method generated a temporary
+              source image if you passed it a colour instead of an image).
+              In this version, this is handled on the C level instead.
+        
+            + Added experimental "RGBa" mode support.
+        
+              An "RGBa" image is an RGBA image where the colour components
+              have have been premultipled with the alpha value.  PIL allows
+              you to convert an RGBA image to an RGBa image, and to paste
+              RGBa images on top of RGB images.  Since this saves a bunch
+              of multiplications and shifts, it is typically about twice
+              as fast an ordinary RGBA paste.
+        
+            + Eliminated extra conversion step when pasting "RGBA" or "RGBa"
+              images on top of "RGB" images.
+        
+            + Fixed Image.BICUBIC resampling for "RGB" images.
+        
+            + Fixed PCX image file handler to properly read 8-bit PCX
+              files (bug introduced in 1.0b1, reported by Bernhard
+              Herzog)
+        
+            + Fixed PSDraw "image" method to restore the coordinate
+              system.
+        
+            + Fixed "blend" problem when applied to images that was
+              not already loaded (reported by Edward C. Jones)
+        
+            + Fixed -f option to "pilconvert.py" (from Anthony Baxter)
+        
+            (1.0b1 released)
+        
+            + Added Toby J. Sargeant's quantization package.  To enable
+              quantization, use the "palette" option to "convert":
+        
+                imOut = im.convert("P", palette=Image.ADAPTIVE)
+        
+              This can be used with "L", "P", and "RGB" images.  In this
+              version, dithering cannot be used with adaptive palettes.
+        
+              Note: ADAPTIVE currently maps to median cut quantization
+              with 256 colours.  The quantization package also contains
+              a maximum coverage quantizer, which will be supported by
+              future versions of PIL.
+        
+            + Added Eric S. Raymond's "pildriver" image calculator to the
+              distribution.  See the docstring for more information.
+        
+            + The "offset" method no longer dumps core if given positive
+              offsets (from Charles Waldman).
+        
+            + Fixed a resource leak that could cause ImageWin to run out of
+              GDI resources (from Roger Burnham).
+        
+            + Added "arc", "chord", and "pieslice" methods to ImageDraw (inspired
+              by code contributed by Richard Jones).
+        
+            + Added experimental 16-bit support, via modes "I;16" (little endian
+              data) and "I;16B" (big endian).  Only a few methods properly support
+              such images (see above).
+        
+            + Added XV thumbnail file handler (from Gene Cash).
+        
+            + Fixed BMP image file handler to handle palette images with small
+              palettes (from Rob Hooft).
+        
+            + Fixed Sun raster file handler for palette images (from Charles
+              Waldman).
+        
+            + Improved various internal error messages.
+        
+            + Fixed Path constructor to handle arbitrary sequence objects.  This
+              also affects the ImageDraw class (from Richard Jones).
+        
+            + Fixed a bug in JpegDecode that caused PIL to report "decoder error
+              -2" for some progressive JPEG files (reported by Magnus Källström,
+              who also provided samples).
+        
+            + Fixed a bug in JpegImagePlugin that caused PIL to hang when loading
+              JPEG files using 16-bit quantization tables.
+        
+            + The Image "transform" method now supports Image.QUAD transforms.
+              The data argument is an 8-tuple giving the upper left, lower
+              left, lower right, and upper right corner of the source quadri-
+              lateral.  Also added Image.MESH transform which takes a list
+              of quadrilaterals.
+        
+            + The Image "resize", "rotate", and "transform" methods now support
+              Image.BILINEAR (2x2) and Image.BICUBIC (4x4) resampling filters.
+              Filters can be used with all transform methods.
+        
+            + The ImageDraw "rectangle" method now includes both the right
+              and the bottom edges when drawing filled rectangles.
+        
+            + The TGA decoder now works properly for runlength encoded images
+              which have more than one byte per pixel.
+        
+            + "getbands" on an YCbCr image now returns ("Y", "Cb", "Cr")
+        
+            + Some file drivers didn't handle the optional "modify" argument
+              to the load method.  This resulted in exceptions when you used
+              "paste" (and other methods that modify an image in place) on a
+              newly opened file.
+        
+            *** Changes from release 0.2 (b5) to 0.3 (b2) ***
+        
+            (0.3b2 released)
+        
+            The test suite includes 825 individual tests.
+        
+            + An Image "getbands" method has been added.  It returns a tuple
+              containing the individual band names for this image.  To figure
+              out how many bands an image has, use "len(im.getbands())".
+        
+            + An Image "putpixel" method has been added.
+        
+            + The Image "point" method can now be used to convert "L" images
+              to any other format, via a lookup table.  That table should
+              contain 256 values for each band in the output image.
+        
+            + Some file drivers (including FLI/FLC, GIF, and IM) accidently
+              overwrote the offset method with an internal attribute.  All
+              drivers have been updated to use private attributes where
+              possible.
+        
+            + The Image "histogram" method now works for "I" and "F" images.
+              For these modes, PIL divides the range between the min and
+              max values used in the image into 256 bins.  You can also
+              pass in your own min and max values via the "extrema" option:
+        
+                h = im.histogram(extrema=(0, 255))
+        
+            + An Image "getextrema" method has been added.  It returns the
+              min and max values used in the image. In this release, this
+              works for single band images only.
+        
+            + Changed the PNG driver to load and save mode "I" images as
+              16-bit images.  When saving, values outside the range 0..65535
+              are clipped.
+        
+            + Fixed ImageFont.py to work with the new "pilfont" compiler.
+        
+            + Added JPEG "save" and "draft" support for mode "YCbCr" images.
+              Note that if you save an "YCbCr" image as a JPEG file and read
+              it back, it is read as an RGB file.  To get around this, you
+              can use the "draft" method:
+        
+                im = Image.open("color.jpg")
+                im.draft("YCbCr", im.size)
+        
+            + Read "RGBA" TGA images.  Also fixed the orientation bug; all
+              images should now come out the right way.
+        
+            + Changed mode name (and internal representation) from "YCrCb"
+              to "YCbCr" (!)
+              *** WARNING: MAY BREAK EXISTING CODE ***
+        
+            (0.3b1 released)
+        
+            The test suite includes 750 individual tests.
+        
+            + The "pilfont" package is now included in the standard PIL
+              distribution.  The pilfont utility can be used to convert
+              X BDF and PCF raster font files to a format understood by
+              the ImageFont module.
+        
+            + GIF files are now interlaced by default.  To write a
+              non-interlaced file, pass interlace=0 to the "save"
+              method.
+        
+            + The default string format has changed for the "fromstring"
+              and "tostring" methods.
+              *** WARNING: MAY BREAK EXISTING CODE ***
+        
+              NOTE: If no extra arguments are given, the first line in
+              the string buffer is the top line of the image, instead of
+              the bottom line.  For RGB images, the string now contains
+              3 bytes per pixel instead of 4.  These changes were made
+              to make the methods compatible with the "fromstring"
+              factory function.
+        
+              To get the old behaviour, use the following syntax:
+        
+                data = im.tostring("raw", "RGBX", 0, -1)
+                im.fromstring(data, "raw", "RGBX", 0, -1)
+        
+            + "new" no longer gives a MemoryError if the width or height
+              is zero (this only happened on platforms where malloc(0)
+              or calloc(0) returns NULL).
+        
+            + "new" now adds a default palette object to "P" images.
+        
+            + You can now convert directly between all modes supported by
+              PIL.  When converting colour images to "P", PIL defaults to
+              a "web" palette and dithering.  When converting greyscale
+              images to "1", PIL uses a thresholding and dithering.
+        
+            + Added a "dither" option to "convert".  By default, "convert"
+              uses floyd-steinberg error diffusion for "P" and "1" targets,
+              so this option is only used to *disable* dithering. Allowed
+              values are NONE (no dithering) or FLOYDSTEINBERG (default).
+        
+                imOut = im.convert("P", dither=Image.NONE)
+        
+            + Added a full set of "I" decoders.  You can use "fromstring"
+              (and file decoders) to read any standard integer type as an
+              "I" image.
+        
+            + Added some support for "YCbCr" images (creation, conversion
+              from/to "L" and "RGB", IM YCC load/save)
+        
+            + "getpixel" now works properly with fractional coordinates.
+        
+            + ImageDraw "setink" now works with "I", "F", "RGB", "RGBA",
+              "RGBX", "CMYK", and "YCbCr" images.
+        
+            + ImImagePlugin no longer attaches palettes to "RGB" images.
+        
+            + Various minor fixes.
+        
+            (0.3a4 released)
+        
+            + Added experimental IPTC/NAA support.
+        
+            + Eliminated AttributeError exceptions after "crop" (from
+              Skip Montanaro)
+        
+            + Reads some uncompressed formats via memory mapping (this
+              is currently supported on Win32 only)
+        
+            + Fixed some last minute glitches in the last alpha release
+              (Types instead of types in Image.py, version numbers, etc.)
+        
+            + Eliminated some more bogus compiler warnings.
+        
+            + Various fixes to make PIL compile and run smoother on Macs
+              (from Jack Jansen).
+        
+            + Fixed "fromstring" and "tostring" for mode "I" images.
+        
+            (0.3a3 released)
+        
+            The test suite includes 530 individual tests.
+        
+            + Eliminated unexpected side-effect in "paste" with matte.  "paste"
+              now works properly also if compiled with "gcc".
+        
+            + Adapted to Python 1.5 (build issues only)
+        
+            + Fixed the ImageDraw "point" method to draw also the last
+              point (!).
+        
+            + Added "I" and "RGBX" support to Image.new.
+        
+            + The plugin path is now properly prepended to the module search
+              path when a plugin module is imported.
+        
+            + Added "draw" method to the ImageWin.Dib class.  This is used by
+              Topaz to print images on Windows printers.
+        
+            + "convert" now supports conversions from "P" to "1" and "F".
+        
+            + "paste" can now take a colour instead of an image as the first argument.
+              The colour must match the colour argument given to the new function, and
+              match the mode of the target image.
+        
+            + Fixed "paste" to allow a mask also for mode "F" images.
+        
+            + The BMP driver now saves mode "1" images.  When loading images, the mode
+              is set to "L" for 8-bit files with greyscale palettes, and to "P" for
+              other 8-bit files.
+        
+            + The IM driver now reads and saves "1" images (file modes "0 1" or "L 1").
+        
+            + The JPEG and GIF drivers now saves "1" images.  For JPEG, the image
+              is saved as 8-bit greyscale (it will load as mode "L").  For GIF, the
+              image will be loaded as a "P" image.
+        
+            + Fixed a potential buffer overrun in the GIF encoder.
+        
+            (0.3a2 released)
+        
+            The test suite includes 400 individual tests.
+        
+            + Improvements to the test suite revealed a number of minor bugs, which
+              are all fixed.  Note that crop/paste, 32-bit ImageDraw, and ImageFont
+              are still weak spots in this release.
+        
+            + Added "putpalette" method to the Image class.  You can use this
+              to add or modify the palette for "P" and "L" images.  If a palette
+              is added to an "L" image, it is automatically converted to a "P"
+              image.
+        
+            + Fixed ImageDraw to properly handle 32-bit image memories
+              ("RGB", "RGBA", "CMYK", "F")
+        
+            + Fixed "fromstring" and "tostring" not to mess up the mode attribute
+              in default mode.
+        
+            + Changed ImPlatform.h to work on CRAY's (don't have one at home, so I
+              haven't tried it).  The previous version assumed that either "short"
+              or "int" were 16-bit wide. PIL still won't compile on platforms where
+              neither "short", "int" nor "long" are 32-bit wide.
+        
+            + Added file= and data= keyword arguments to PhotoImage and BitmapImage.
+              This allows you to use them as drop-in replacements for the corre-
+              sponding Tkinter classes.
+        
+            + Removed bogus references to the crack coder (ImagingCrack).
+        
+            (0.3a1 released)
+        
+            + Make sure image is loaded in "tostring".
+        
+            + Added floating point packer (native 32-bit floats only).
+        
+            *** Changes from release 0.1b1 to 0.2 (b5) ***
+        
+            + Modified "fromstring" and "tostring" methods to use file codecs.
+              Also added "fromstring" factory method to create an image directly
+              from data in a string.
+        
+            + Added support for 32-bit floating point images (mode "F").  You
+              can convert between "L" and "F" images, and apply a subset of the
+              available image processing methods on the "F" image.  You can also
+              read virtually any data format into a floating point image memory;
+              see the section on "Decoding Floating Point Data" in the handbook
+              for more information.
+        
+            (0.2b5 released; on windows only)
+        
+            + Fixed the tobitmap() method to work properly for small bitmaps.
+        
+            + Added RMS and standard deviation to the ImageStat.Stat class.  Also
+              modified the constructor to take an optional feature mask, and also
+              to accept either an image or a list containing the histogram data.
+        
+            + The BitmapImage code in ImageTk can now use a special bitmap
+              decoder, which has to be patched into Tk.  See the "Tk/pilbitmap.txt"
+              file for details.  If not installed, bitmaps are transferred to Tk as
+              XBM strings.
+        
+            + The PhotoImage code in ImageTk now uses a Tcl command ("PyImagingPaste")
+              instead of a special image type.  This gives somewhat better performance,
+              and also allows PIL to support transparency.
+              *** WARNING: TKAPPINIT MUST BE MODIFIED ***
+        
+            + ImageTk now honours the alpha layer in RGBA images.  Only fully
+              transparent pixels are made transparent (that is, the alpha layer
+              is treated as a mask).  To treat the alpha laters as a matte, you
+              must paste the image on the background before handing it over to
+              ImageTk.
+        
+            + Added McIdas reader (supports 8-bit images only).
+        
+            + PIL now preloads drivers for BMP, GIF, JPEG, PPM, and TIFF.  As
+              long as you only load and save these formats, you don't have to
+              wait for a full scan for drivers.  To force scanning, call the
+              Image.init() function.
+        
+            + The "seek" and "tell" methods are now always available, also for
+              single-frame images.
+        
+            + Added optional mask argument to histogram method.  The mask may
+              be an "1" or "L" image with the same size as the original image.
+              Only pixels where the mask is non-zero are included in the
+              histogram.
+        
+            + The "paste" method now allows you to specify only the lower left
+              corner (a 2-tuple), instead of the full region (a 4-tuple).
+        
+            + Reverted to old plugin scanning model; now scans all directory
+              names in the path when looking for plugins.
+        
+            + Added PIXAR raster support.  Only uncompressed ("dumped") RGB
+              images can currently be read (based on information provided
+              by Greg Coats).
+        
+            + Added FlashPix (FPX) read support.  Reads all pixel formats, but
+              only the highest resolution is read, and the viewing transform is
+              currently ignored.
+        
+            + Made PNG encoding somewhat more efficient in "optimize" mode; a
+              bug in 0.2b4 didn't enable all predictor filters when optimized
+              storage were requested.
+        
+            + Added Microsoft Image Composer (MIC) read support.  When opened,
+              the first sprite in the file is loaded.  You can use the seek method
+              to load additional sprites from the file.
+        
+            + Properly reads "P" and "CMYK" PSD images.
+        
+            + "pilconvert" no longer optimizes by default; use the -o option to
+              make the file as small as possible (at the expense of speed); use
+              the -q option to set the quality when compressing to JPEG.
+        
+            + Fixed "crop" not to drop the palette for "P" images.
+        
+            + Added and verified FLC support.
+        
+            + Paste with "L" or "RGBA" alpha is now several times faster on most
+              platforms.
+        
+            + Changed Image.new() to initialize the image to black, as described
+              in the handbook.  To get an uninitialized image, use None as the
+              colour.
+        
+            + Fixed the PDF encoder to produce a valid header; Acrobat no longer
+              complains when you load PDF images created by PIL.
+        
+            + PIL only scans fully-qualified directory names in the path when
+              looking for plugins.
+              *** WARNING: MAY BREAK EXISTING CODE ***
+        
+            + Faster implementation of "save" used when filename is given,
+              or when file object has "fileno" and "flush" methods.
+        
+            + Don't crash in "crop" if region extends outside the source image.
+        
+            + Eliminated a massive memory leak in the "save" function.
+        
+            + The GIF decoder doesn't crash if the code size is set to an illegal
+              value.  This could happen since another bug didn't handle local
+              palettes properly if they didn't have the same size as the
+              global palette (not very common).
+        
+            + Added predictor support (TIFF 6.0 section 14) to the TIFF decoder.
+        
+            + Fixed palette and padding problems in BMP driver.  Now properly
+              writes "1", "L", "P" and "RGB" images.
+        
+            + Fixed getpixel()/getdata() to return correct pixel values.
+        
+            + Added PSD (PhotoShop) read support.  Reads both uncompressed
+              and compressed images of most types.
+        
+            + Added GIF write support (writes "uncompressed" GIF files only,
+              due to unresolvable licensing issues).  The "gifmaker.py" script
+              can be used to create GIF animations.
+        
+            + Reads 8-bit "L" and "P" TGA images.  Also reads 16-bit "RGB"
+              images.
+        
+            + Added FLI read support.  This driver has only been tested
+              on a few FLI samples.
+        
+            + Reads 2-bit and 4-bit PCX images.
+        
+            + Added MSP read and write support.  Both version 1 and 2 can be
+              read, but only version 1 (uncompressed) files are written.
+        
+            + Fixed a bug in the FLI/FLC identification code that caused the
+              driver to raise an exception when parsing valid FLI/FLC files.
+        
+            + Improved performance when loading file format plugins, and when
+              opening files.
+        
+            + Added GIF animation support, via the "seek" and "tell" methods.
+              You can use "player.py" to play an animated GIF file.
+        
+            + Removed MNG support, since the spec is changing faster than I
+              can change the code.  I've added support for the experimental
+              ARG format instead.  Contact me for more information on this
+              format.
+        
+            + Added keyword options to the "save" method.  The following options
+              are currently supported:
+        
+                  format	option		description
+                  --------------------------------------------------------
+                  JPEG	optimize	minimize output file at the
+                            expense of compression speed.
+        
+                  JPEG	progressive	enable progressive output. the
+                            option value is ignored.
+        
+                  JPEG	quality		set compression quality (1-100).
+                            the default value is 75.
+        
+                  JPEG	smooth		smooth dithered images.  value
+                            is strengh (1-100).  default is
+                            off (0).
+        
+                  PNG	optimize	minimize output file at the
+                            expense of compression speed.
+        
+              Expect more options in future releases.  Also note that
+              file writers silently ignore unknown options.
+        
+            + Plugged memory leaks in the PNG and TIFF decoders.
+        
+            + Added PNG write support.
+        
+            + (internal) RGB unpackers and converters now set the pad byte
+              to 255 (full opacity).
+        
+            + Properly handles the "transparency" property for GIF, PNG
+              and XPM files.
+        
+            + Added a "putalpha" method, allowing you to attach a "1" or "L"
+              image as the alpha layer to an "RGBA" image.
+        
+            + Various improvements to the sample scripts:
+        
+              "pilconvert"  Carries out some extra tricks in order to make
+                    the resulting file as small as possible.
+        
+              "explode"	(NEW) Split an image sequence into individual frames.
+        
+              "gifmaker"	(NEW) Convert a sequence file into a GIF animation.
+                    Note that the GIF encoder create "uncompressed" GIF
+                    files, so animations created by this script are
+                    rather large (typically 2-5 times the compressed
+                    sizes).
+        
+              "image2py"	(NEW) Convert a single image to a python module.  See
+                    comments in this script for details.
+        
+              "player"	If multiple images are given on the command line,
+                    they are interpreted as frames in a sequence.  The
+                    script assumes that they all have the same size.
+                    Also note that this script now can play FLI/FLC
+                    and GIF animations.
+        
+                    This player can also execute embedded Python
+                    animation applets (ARG format only).
+        
+              "viewer"	Transparent images ("P" with transparency property,
+                    and "RGBA") are superimposed on the standard Tk back-
+                    ground.
+        
+            + Fixed colour argument to "new".  For multilayer images, pass a
+              tuple: (Red, Green, Blue), (Red, Green, Blue, Alpha), or (Cyan,
+              Magenta, Yellow, Black).
+        
+            + Added XPM (X pixmap) read support.
+        
+            (0.2b3 released)
+        
+            + Added MNG (multi-image network graphics) read support.  "Ming"
+              is a proposed animation standard, based on the PNG file format.
+        
+              You can use the "player" sample script to display some flavours
+              of this format.  The MNG standard is still under development,
+              as is this driver.  More information, including sample files,
+              can be found at <ftp://swrinde.nde.swri.edu/pub/mng>
+        
+            + Added a "verify" method to images loaded from file.  This method
+              scans the file for errors, without actually decoding the image
+              data, and raises a suitable exception if it finds any problems.
+              Currently implemented for PNG and MNG files only.
+        
+            + Added support for interlaced GIF images.
+        
+            + Added PNG read support -- if linked with the ZLIB compression library,
+              PIL reads all kinds of PNG images, except interlaced files.
+        
+            + Improved PNG identification support -- doesn't mess up on unknown
+              chunks, identifies all possible PNG modes, and verifies checksum
+              on PNG header chunks.
+        
+            + Added an experimental reader for placable Windows Meta Files (WMF).
+              This reader is still very incomplete, but it illustrates how PIL's
+              drawing capabilities can be used to render vector and metafile
+              formats.
+        
+            + Added restricted drivers for images from Image Tools (greyscale
+              only) and LabEye/IFUNC (common interchange modes only).
+        
+            + Some minor improvements to the sample scripts provided in the
+              "Scripts" directory.
+        
+            + The test images have been moved to the "Images" directory.
+        
+            (0.2b2 released)
+            (0.2b1 released; Windows only)
+        
+            + Fixed filling of complex polygons.  The ImageDraw "line" and
+              "polygon" methods also accept Path objects.
+        
+            + The ImageTk "PhotoImage" object can now be constructed directly
+              from an image.  You can also pass the object itself to Tkinter,
+              instead of using the "image" attribute.  Finally, using "paste"
+              on a displayed image automatically updates the display.
+        
+            + The ImageTk "BitmapImage" object allows you to create transparent
+              overlays from 1-bit images.  You can pass the object itself to
+              Tkinter.  The constructor takes the same arguments as the Tkinter
+              BitmapImage class; use the "foreground" option to set the colour
+              of the overlay.
+        
+            + Added a "putdata" method to the Image class.  This can be used to
+              load a 1-layer image with data from a sequence object or a string.
+              An optional floating point scale and offset can be used to adjust
+              the data to fit into the 8-bit pixel range.  Also see the "getdata"
+              method.
+        
+            + Added the EXTENT method to the Image "transform" method.  This can
+              be used to quickly crop, stretch, shrink, or mirror a subregion
+              from another image.
+        
+            + Adapted to Python 1.4.
+        
+            + Added a project makefile for Visual C++ 4.x.  This allows you to
+              easily build a dynamically linked version of PIL for Windows 95
+              and NT.
+        
+            + A Tk "booster" patch for Windows is available.  It gives dramatic
+              performance improvements for some displays.  Has been tested with
+              Tk 4.2 only, but is likely to work with Tk 4.1 as well.  See the Tk
+              subdirectory for details.
+        
+            + You can now save 1-bit images in the XBM format.  In addition, the
+              Image class now provides a "tobitmap" method which returns a string
+              containing an XBM representation of the image.  Quite handy to use
+              with Tk.
+        
+            + More conversions, including "RGB" to "1" and more.
+        
+            (0.2a1 released)
+        
+            + Where earlier versions accepted lists, this version accepts arbitrary
+              Python sequences (including strings, in some cases).  A few resource
+              leaks were plugged in the process.
+        
+            + The Image "paste" method now allows the box to extend outside
+              the target image.  The size of the box, the image to be pasted,
+              and the optional mask must still match.
+        
+            + The ImageDraw module now supports filled polygons, outlined and
+              filled ellipses, and text.  Font support is rudimentary, though.
+        
+            + The Image "point" method now takes an optional mode argument,
+              allowing you to convert the image while translating it.  Currently,
+              this can only be used to convert "L" or "P" images to "1" images
+              (creating thresholded images or "matte" masks).
+        
+            + An Image "getpixel" method has been added.  For single band images,
+              it returns the pixel value at a given position as an integer.
+              For n-band images, it returns an n-tuple of integers.
+        
+            + An Image "getdata" method has been added.  It returns a sequence
+              object representing the image as a 1-dimensional array.  Only len()
+              and [] can be used with this sequence.  This method returns a
+              reference to the existing image data, so changes in the image
+              will be immediately reflected in the sequence object.
+        
+            + Fixed alignment problems in the Windows BMP writer.
+        
+            + If converting an "RGB" image to "RGB" or "L", you can give a second
+              argument containing a colour conversion matrix.
+        
+            + An Image "getbbox" method has been added.  It returns the bounding
+              box of data in an image, considering the value 0 as background.
+        
+            + An Image "offset" method has been added.  It returns a new image
+              where the contents of the image have been offset the given distance
+              in X and/or Y direction.  Data wraps between edges.
+        
+            + Saves PDF images.  The driver creates a binary PDF 1.1 files, using
+              JPEG compression for "L", "RGB", and "CMYK" images, and hex encoding
+              (same as for PostScript) for other formats.
+        
+            + The "paste" method now accepts "1" masks.  Zero means transparent,
+              any other pixel value means opaque.  This is faster than using an
+              "L" transparency mask.
+        
+            + Properly writes EPS files (and properly prints images to postscript
+              printers as well).
+        
+            + Reads 4-bit BMP files, as well as 4 and 8-bit Windows ICO and CUR
+              files.  Cursor animations are not supported.
+        
+            + Fixed alignment problems in the Sun raster loader.
+        
+            + Added "draft" and "thumbnail" methods.  The draft method is used
+              to optimize loading of JPEG and PCD files, the thumbnail method is
+              used to create a thumbnail representation of an image.
+        
+            + Added Windows display support, via the ImageWin class (see the
+              handbook for details).
+        
+            + Added raster conversion for EPS files.  This requires GNU or Aladdin
+              Ghostscript, and probably works on UNIX only.
+        
+            + Reads PhotoCD (PCD) images.  The base resolution (768x512) can be
+              read from a PhotoCD file.
+        
+            + Eliminated some compiler warnings.  Bindings now compile cleanly in C++
+              mode.  Note that the Imaging library itself must be compiled in C mode.
+        
+            + Added "bdf2pil.py", which converts BDF fonts into images with associated
+              metrics.  This is definitely work in progress.  For info, see description
+              in script for details.
+        
+            + Fixed a bug in the "ImageEnhance.py" module.
+        
+            + Fixed a bug in the netpbm save hack in "GifImagePlugin.py"
+        
+            + Fixed 90 and 270 degree rotation of rectangular images.
+        
+            + Properly reads 8-bit TIFF palette-color images.
+        
+            + Reads plane separated RGB and CMYK TIFF images.
+        
+            + Added driver debug mode.  This is enabled by setting Image.DEBUG
+              to a non-zero value.  Try the -D option to "pilfile.py" and see what
+              happens.
+        
+            + Don't crash on "atend" constructs in PostScript files.
+        
+            + Only the Image module imports _imaging directly.  Other modules
+              should refer to the binding module as "Image.core".
+        
+            *** Changes from release 0.0 to 0.1 (b1) ***
+        
+            + A handbook is available (distributed separately).
+        
+            + The coordinate system is changed so that (0,0) is now located
+              in the upper left corner.  This is in compliancy with ISO 12087
+              and 90% of all other image processing and graphics libraries.
+        
+            + Modes "1" (bilevel) and "P" (palette) have been introduced.  Note
+              that bilevel images are stored with one byte per pixel.
+        
+            + The Image "crop" and "paste" methods now accepts None as the
+              box argument, to refer to the full image (self, that is).
+        
+            + The Image "crop" method now works properly.
+        
+            + The Image "point" method is now available.  You can use either a
+              lookup table or a function taking one argument.
+        
+            + The Image join function has been renamed to "merge".
+        
+            + An Image "composite" function has been added.  It is identical
+              to copy() followed by paste(mask).
+        
+            + An Image "eval" function has been added.  It is currently identical
+              to point(function); that is, only a single image can be processed.
+        
+            + A set of channel operations has been added.  See the "ImageChops"
+              module, test_chops.py, and the handbook for details.
+        
+            + Added the "pilconvert" utility, which converts image files.  Note
+              that the number of output formats are still quite restricted.
+        
+            + Added the "pilfile" utility, which quickly identifies image files
+              (without loading them, in most cases).
+        
+            + Added the "pilprint" utility, which prints image files to Postscript
+              printers.
+        
+            + Added a rudimentary version of the "pilview" utility, which is
+              simple image viewer based on Tk.  Only File/Exit and Image/Next
+              works properly.
+        
+            + An interface to Tk has been added.  See "Lib/ImageTk.py" and README
+              for details.
+        
+            + An interface to Jack Jansen's Img library has been added (thanks to
+              Jack).  This allows you to read images through the Img extensions file
+              format handlers.  See the file "Lib/ImgExtImagePlugin.py" for details.
+        
+            + Postscript printing is provided through the PSDraw module.  See the
+              handbook for details.

+Description: SQLAlchemy
+        ==========
+        
+        The Python SQL Toolkit and Object Relational Mapper
+        
+        Introduction
+        -------------
+        
+        SQLAlchemy is the Python SQL toolkit and Object Relational Mapper
+        that gives application developers the full power and
+        flexibility of SQL. SQLAlchemy provides a full suite
+        of well known enterprise-level persistence patterns,
+        designed for efficient and high-performing database
+        access, adapted into a simple and Pythonic domain
+        language.
+        
+        Major SQLAlchemy features include:
+        
+        * An industrial strength ORM, built 
+          from the core on the identity map, unit of work,
+          and data mapper patterns.   These patterns
+          allow transparent persistence of objects 
+          using a declarative configuration system.
+          Domain models
+          can be constructed and manipulated naturally,
+          and changes are synchronized with the
+          current transaction automatically.
+        * A relationally-oriented query system, exposing
+          the full range of SQL's capabilities 
+          explicitly, including joins, subqueries, 
+          correlation, and most everything else, 
+          in terms of the object model.
+          Writing queries with the ORM uses the same 
+          techniques of relational composition you use 
+          when writing SQL.  While you can drop into
+          literal SQL at any time, it's virtually never
+          needed.
+        * A comprehensive and flexible system 
+          of eager loading for related collections and objects.
+          Collections are cached within a session,
+          and can be loaded on individual access, all 
+          at once using joins, or by query per collection
+          across the full result set.
+        * A Core SQL construction system and DBAPI 
+          interaction layer.  The SQLAlchemy Core is
+          separate from the ORM and is a full database
+          abstraction layer in its own right, and includes
+          an extensible Python-based SQL expression 
+          language, schema metadata, connection pooling, 
+          type coercion, and custom types.
+        * All primary and foreign key constraints are 
+          assumed to be composite and natural.  Surrogate
+          integer primary keys are of course still the 
+          norm, but SQLAlchemy never assumes or hardcodes
+          to this model.
+        * Database introspection and generation.  Database
+          schemas can be "reflected" in one step into
+          Python structures representing database metadata;
+          those same structures can then generate 
+          CREATE statements right back out - all within
+          the Core, independent of the ORM.
+        
+        SQLAlchemy's philosophy:
+        
+        * SQL databases behave less and less like object
+          collections the more size and performance start to
+          matter; object collections behave less and less like
+          tables and rows the more abstraction starts to matter.
+          SQLAlchemy aims to accommodate both of these
+          principles.
+        * An ORM doesn't need to hide the "R".   A relational
+          database provides rich, set-based functionality
+          that should be fully exposed.   SQLAlchemy's
+          ORM provides an open-ended set of patterns
+          that allow a developer to construct a custom
+          mediation layer between a domain model and 
+          a relational schema, turning the so-called
+          "object relational impedance" issue into
+          a distant memory.
+        * The developer, in all cases, makes all decisions
+          regarding the design, structure, and naming conventions
+          of both the object model as well as the relational
+          schema.   SQLAlchemy only provides the means
+          to automate the execution of these decisions.
+        * With SQLAlchemy, there's no such thing as 
+          "the ORM generated a bad query" - you 
+          retain full control over the structure of 
+          queries, including how joins are organized,
+          how subqueries and correlation is used, what 
+          columns are requested.  Everything SQLAlchemy
+          does is ultimately the result of a developer-
+          initiated decision.
+        * Don't use an ORM if the problem doesn't need one.
+          SQLAlchemy consists of a Core and separate ORM
+          component.   The Core offers a full SQL expression
+          language that allows Pythonic construction 
+          of SQL constructs that render directly to SQL
+          strings for a target database, returning
+          result sets that are essentially enhanced DBAPI
+          cursors.
+        * Transactions should be the norm.  With SQLAlchemy's
+          ORM, nothing goes to permanent storage until
+          commit() is called.  SQLAlchemy encourages applications
+          to create a consistent means of delineating
+          the start and end of a series of operations.
+        * Never render a literal value in a SQL statement.
+          Bound parameters are used to the greatest degree
+          possible, allowing query optimizers to cache 
+          query plans effectively and making SQL injection
+          attacks a non-issue.

+Version: 1.2-17-g3b12acf
+Summary: Ed25519 public-key signatures
+Home-page: https://github.com/warner/python-ed25519
+Author: Brian Warner
+Author-email: warner-python-ed25519@lothar.com
+License: MIT
+Description: Python bindings to the Ed25519 public-key signature system.
+        
+        This offers a comfortable python interface to a C implementation of the
+        Ed25519 public-key signature system (http://ed25519.cr.yp.to/), using the
+        portable 'ref' code from the 'SUPERCOP' benchmarking suite.
+        
+        This system provides high (128-bit) security, short (32-byte) keys, short
+        (64-byte) signatures, and fast (2-6ms) operation. Please see the README for
+        more details.
+

+Package resource API
+--------------------
+
+A resource is a logical file contained within a package, or a logical
+subdirectory thereof.  The package resource API expects resource names
+to have their path parts separated with ``/``, *not* whatever the local
+path separator is.  Do not use os.path operations to manipulate resource
+names being passed into the API.
+
+The package resource API is designed to work with normal filesystem packages,
+.egg files, and unpacked .egg files.  It can also work in a limited way with
+.zip files and with custom PEP 302 loaders that support the ``get_data()``
+method.

+
+    This is a rough cross between distutils' StrictVersion and LooseVersion;

+    the same; otherwise it acts like a slightly-smarter LooseVersion. It is
+    *possible* to create pathological version coding schemes that will fool
+    this parser, but they should be very rare in practice.
+
+    The returned value will be a tuple of strings.  Numeric portions of the
+    version are padded to 8 digits so they will compare numerically, but
+    without relying on how numbers compare relative to strings.  Dots are
+    dropped, but dashes are retained.  Trailing zeros between alpha segments
+    or dashes are suppressed, so that e.g. "2.4.0" is considered the same as
+    "2.4". Alphanumeric parts are lower-cased.
+
+    The algorithm assumes that strings like "-" and any alpha string that
+    alphabetically follows "final"  represents a "patch level".  So, "2.4-1"
+    is assumed to be a branch or patch of "2.4", and therefore "2.4.1" is
+    considered newer than "2.4-1", which in turn is newer than "2.4".
+
+    Strings like "a", "b", "c", "alpha", "beta", "candidate" and so on (that
+    come before "final" alphabetically) are assumed to be pre-release versions,
+    so that the version "2.4" is considered newer than "2.4a1".
+
+    Finally, to handle miscellaneous cases, the strings "pre", "preview", and
+    "rc" are treated as if they were "c", i.e. as though they were release
+    candidates, and therefore are not as new as a version string that does not
+    contain them, and "dev" is replaced with an '@' so that it sorts lower than
+    than any other pre-release tag.

+===============================
+Installing and Using Setuptools
+===============================
+
+.. contents:: **Table of Contents**
+
+
+-------------------------
+Installation Instructions
+-------------------------
+
+Upgrading from Distribute
+=========================
+
+Currently, Distribute disallows installing Setuptools 0.7+ over Distribute.
+You must first uninstall any active version of Distribute first (see
+`Uninstalling`_).
+
+Upgrading from Setuptools 0.6
+=============================
+
+Upgrading from prior versions of Setuptools is supported. Initial reports
+good success in this regard.
+
+Windows
+=======
+
+The recommended way to install setuptools on Windows is to download
+`ez_setup.py`_ and run it. The script will download the appropriate .egg
+file and install it for you.
+
+.. _ez_setup.py: https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py
+
+For best results, uninstall previous versions FIRST (see `Uninstalling`_).
+
+Once installation is complete, you will find an ``easy_install`` program in
+your Python ``Scripts`` subdirectory.  For simple invocation and best results,
+add this directory to your ``PATH`` environment variable, if it is not already
+present.
+
+
+Unix-based Systems including Mac OS X
+=====================================
+
+Download `ez_setup.py`_ and run it using the target Python version. The script
+will download the appropriate version and install it for you::
+
+    > wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | python
+
+Note that you will may need to invoke the command with superuser privileges to
+install to the system Python::
+
+    > wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | sudo python
+
+Alternatively, on Python 2.6 and later, Setuptools may be installed to a
+user-local path::
+
+    > wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py
+    > python ez_setup.py --user
+
+
+Python 2.4 and Python 2.5 support
+=================================
+
+Setuptools 2.0 and later requires Python 2.6 or later. To install setuptools
+on Python 2.4 or Python 2.5, use the bootstrap script for Setuptools 1.x:
+https://bitbucket.org/pypa/setuptools/raw/bootstrap-py24/ez_setup.py.
+
+
+Advanced Installation
+=====================
+
+For more advanced installation options, such as installing to custom
+locations or prefixes, download and extract the source
+tarball from `Setuptools on PyPI <https://pypi.python.org/pypi/setuptools>`_
+and run setup.py with any supported distutils and Setuptools options.
+For example::
+
+    setuptools-x.x$ python setup.py --prefix=/opt/setuptools
+
+Use ``--help`` to get a full options list, but we recommend consulting
+the `EasyInstall manual`_ for detailed instructions, especially `the section
+on custom installation locations`_.
+
+.. _EasyInstall manual: https://pythonhosted.org/setuptools/EasyInstall
+.. _the section on custom installation locations: https://pythonhosted.org/setuptools/EasyInstall#custom-installation-locations
+
+
+Downloads
+=========
+
+All setuptools downloads can be found at `the project's home page in the Python
+Package Index`_.  Scroll to the very bottom of the page to find the links.
+
+.. _the project's home page in the Python Package Index: https://pypi.python.org/pypi/setuptools
+
+In addition to the PyPI downloads, the development version of ``setuptools``
+is available from the `Bitbucket repo`_, and in-development versions of the
+`0.6 branch`_ are available as well.
+
+.. _Bitbucket repo: https://bitbucket.org/pypa/setuptools/get/default.tar.gz#egg=setuptools-dev
+.. _0.6 branch: http://svn.python.org/projects/sandbox/branches/setuptools-0.6/#egg=setuptools-dev06
+
+Uninstalling
+============
+
+On Windows, if Setuptools was installed using an ``.exe`` or ``.msi``
+installer, simply use the uninstall feature of "Add/Remove Programs" in the
+Control Panel.
+
+Otherwise, to uninstall Setuptools or Distribute, regardless of the Python
+version, delete all ``setuptools*`` and ``distribute*`` files and
+directories from your system's ``site-packages`` directory
+(and any other ``sys.path`` directories) FIRST.
+
+If you are upgrading or otherwise plan to re-install Setuptools or Distribute,
+nothing further needs to be done. If you want to completely remove Setuptools,
+you may also want to remove the 'easy_install' and 'easy_install-x.x' scripts
+and associated executables installed to the Python scripts directory.
+
+--------------------------------
+Using Setuptools and EasyInstall
+--------------------------------
+
+Here are some of the available manuals, tutorials, and other resources for
+learning about Setuptools, Python Eggs, and EasyInstall:
+
+* `The EasyInstall user's guide and reference manual`_
+* `The setuptools Developer's Guide`_
+* `The pkg_resources API reference`_
+* `Package Compatibility Notes`_ (user-maintained)
+* `The Internal Structure of Python Eggs`_
+
+Questions, comments, and bug reports should be directed to the `distutils-sig
+mailing list`_.  If you have written (or know of) any tutorials, documentation,
+plug-ins, or other resources for setuptools users, please let us know about
+them there, so this reference list can be updated.  If you have working,
+*tested* patches to correct problems or add features, you may submit them to
+the `setuptools bug tracker`_.

+Credits
+-------
+
+* The original design for the ``.egg`` format and the ``pkg_resources`` API was
+  co-created by Phillip Eby and Bob Ippolito.  Bob also implemented the first
+  version of ``pkg_resources``, and supplied the OS X operating system version
+  compatibility algorithm.
+
+* Ian Bicking implemented many early "creature comfort" features of
+  easy_install, including support for downloading via Sourceforge and
+  Subversion repositories.  Ian's comments on the Web-SIG about WSGI
+  application deployment also inspired the concept of "entry points" in eggs,
+  and he has given talks at PyCon and elsewhere to inform and educate the
+  community about eggs and setuptools.
+
+* Jim Fulton contributed time and effort to build automated tests of various
+  aspects of ``easy_install``, and supplied the doctests for the command-line
+  ``.exe`` wrappers on Windows.
+
+* Phillip J. Eby is the seminal author of setuptools, and
+  first proposed the idea of an importable binary distribution format for
+  Python application plug-ins.
+
+* Significant parts of the implementation of setuptools were funded by the Open
+  Source Applications Foundation, to provide a plug-in infrastructure for the
+  Chandler PIM application.  In addition, many OSAF staffers (such as Mike
+  "Code Bear" Taylor) contributed their time and stress as guinea pigs for the
+  use of eggs and setuptools, even before eggs were "cool".  (Thanks, guys!)
+
+* Since the merge with Distribute, Jason R. Coombs is the
+  maintainer of setuptools.  The project is maintained in coordination with
+  the Python Packaging Authority (PyPA) and the larger Python community.

+* `Issue #124 <https://bitbucket.org/pypa/setuptools/issue/124>`_: Fixed error in list detection in upload_docs.
+
+---
+2.0
+---
+
+* `Issue #121 <https://bitbucket.org/pypa/setuptools/issue/121>`_: Exempt lib2to3 pickled grammars from DirectorySandbox.
+* `Issue #41 <https://bitbucket.org/pypa/setuptools/issue/41>`_: Dropped support for Python 2.4 and Python 2.5. Clients requiring
+  setuptools for those versions of Python should use setuptools 1.x.
+* Removed ``setuptools.command.easy_install.HAS_USER_SITE``. Clients
+  expecting this boolean variable should use ``site.ENABLE_USER_SITE``
+  instead.
+* Removed ``pkg_resources.ImpWrapper``. Clients that expected this class
+  should use ``pkgutil.ImpImporter`` instead.
+
+-----
+1.4.2
+-----
+
+* `Issue #116 <https://bitbucket.org/pypa/setuptools/issue/116>`_: Correct TypeError when reading a local package index on Python
+  3.
+
+-----
+1.4.1
+-----
+
+* `Issue #114 <https://bitbucket.org/pypa/setuptools/issue/114>`_: Use ``sys.getfilesystemencoding`` for decoding config in
+  ``bdist_wininst`` distributions.
+
+* `Issue #105 <https://bitbucket.org/pypa/setuptools/issue/105>`_ and `Issue #113 <https://bitbucket.org/pypa/setuptools/issue/113>`_: Establish a more robust technique for
+  determining the terminal encoding::
+
+    1. Try ``getpreferredencoding``
+    2. If that returns US_ASCII or None, try the encoding from
+       ``getdefaultlocale``. If that encoding was a "fallback" because Python
+       could not figure it out from the environment or OS, encoding remains
+       unresolved.
+    3. If the encoding is resolved, then make sure Python actually implements
+       the encoding.
+    4. On the event of an error or unknown codec, revert to fallbacks
+       (UTF-8 on Darwin, ASCII on everything else).
+    5. On the encoding is 'mac-roman' on Darwin, use UTF-8 as 'mac-roman' was
+       a bug on older Python releases.
+
+    On a side note, it would seem that the encoding only matters for when SVN
+    does not yet support ``--xml`` and when getting repository and svn version
+    numbers. The ``--xml`` technique should yield UTF-8 according to some
+    messages on the SVN mailing lists. So if the version numbers are always
+    7-bit ASCII clean, it may be best to only support the file parsing methods
+    for legacy SVN releases and support for SVN without the subprocess command
+    would simple go away as support for the older SVNs does.
+
+---
+1.4
+---
+
+* `Issue #27 <https://bitbucket.org/pypa/setuptools/issue/27>`_: ``easy_install`` will now use credentials from .pypirc if
+  present for connecting to the package index.
+* `Pull Request #21 <https://bitbucket.org/pypa/setuptools/pull-request/21>`_: Omit unwanted newlines in ``package_index._encode_auth``
+  when the username/password pair length indicates wrapping.
+
+-----
+1.3.2
+-----
+
+* `Issue #99 <https://bitbucket.org/pypa/setuptools/issue/99>`_: Fix filename encoding issues in SVN support.
+
+-----
+1.3.1
+-----
+
+* Remove exuberant warning in SVN support when SVN is not used.
+
+---
+1.3
+---
+
+* Address security vulnerability in SSL match_hostname check as reported in
+  `Python #17997 <http://bugs.python.org/issue17997>`_.
+* Prefer `backports.ssl_match_hostname
+  <https://pypi.python.org/pypi/backports.ssl_match_hostname>`_ for backport
+  implementation if present.

+
+---
+1.2
+---
+
+* `Issue #26 <https://bitbucket.org/pypa/setuptools/issue/26>`_: Add support for SVN 1.7. Special thanks to Philip Thiem for the
+  contribution.
+* `Issue #93 <https://bitbucket.org/pypa/setuptools/issue/93>`_: Wheels are now distributed with every release. Note that as
+  reported in `Issue #108 <https://bitbucket.org/pypa/setuptools/issue/108>`_, as of Pip 1.4, scripts aren't installed properly
+  from wheels. Therefore, if using Pip to install setuptools from a wheel,
+  the ``easy_install`` command will not be available.
+* Setuptools "natural" launcher support, introduced in 1.0, is now officially
+  supported.
+
+-----
+1.1.7
+-----
+
+* Fixed behavior of NameError handling in 'script template (dev).py' (script
+  launcher for 'develop' installs).
+* ``ez_setup.py`` now ensures partial downloads are cleaned up following
+  a failed download.
+* `Distribute #363 <https://bitbucket.org/tarek/distribute/issue/363>`_ and `Issue #55 <https://bitbucket.org/pypa/setuptools/issue/55>`_: Skip an sdist test that fails on locales
+  other than UTF-8.
+
+-----
+1.1.6
+-----
+
+* `Distribute #349 <https://bitbucket.org/tarek/distribute/issue/349>`_: ``sandbox.execfile`` now opens the target file in binary
+  mode, thus honoring a BOM in the file when compiled.
+
+-----
+1.1.5
+-----
+
+* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Second attempt at fix (logic was reversed).
+
+-----
+1.1.4
+-----
+
+* `Issue #77 <https://bitbucket.org/pypa/setuptools/issue/77>`_: Fix error in upload command (Python 2.4).
+
+-----
+1.1.3
+-----
+
+* Fix NameError in previous patch.
+
+-----
+1.1.2
+-----
+
+* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Correct issue where 404 errors are returned for URLs with
+  fragments in them (such as #egg=).
+
+-----
+1.1.1
+-----
+
+* `Issue #75 <https://bitbucket.org/pypa/setuptools/issue/75>`_: Add ``--insecure`` option to ez_setup.py to accommodate
+  environments where a trusted SSL connection cannot be validated.
+* `Issue #76 <https://bitbucket.org/pypa/setuptools/issue/76>`_: Fix AttributeError in upload command with Python 2.4.
+
+---
+1.1
+---
+
+* `Issue #71 <https://bitbucket.org/pypa/setuptools/issue/71>`_ (`Distribute #333 <https://bitbucket.org/tarek/distribute/issue/333>`_): EasyInstall now puts less emphasis on the
+  condition when a host is blocked via ``--allow-hosts``.
+* `Issue #72 <https://bitbucket.org/pypa/setuptools/issue/72>`_: Restored Python 2.4 compatibility in ``ez_setup.py``.
+
+---
+1.0
+---
+
+* `Issue #60 <https://bitbucket.org/pypa/setuptools/issue/60>`_: On Windows, Setuptools supports deferring to another launcher,
+  such as Vinay Sajip's `pylauncher <https://bitbucket.org/pypa/pylauncher>`_
+  (included with Python 3.3) to launch console and GUI scripts and not install
+  its own launcher executables. This experimental functionality is currently
+  only enabled if  the ``SETUPTOOLS_LAUNCHER`` environment variable is set to
+  "natural". In the future, this behavior may become default, but only after
+  it has matured and seen substantial adoption. The ``SETUPTOOLS_LAUNCHER``
+  also accepts "executable" to force the default behavior of creating launcher
+  executables.
+* `Issue #63 <https://bitbucket.org/pypa/setuptools/issue/63>`_: Bootstrap script (ez_setup.py) now prefers Powershell, curl, or
+  wget for retrieving the Setuptools tarball for improved security of the
+  install. The script will still fall back to a simple ``urlopen`` on
+  platforms that do not have these tools.
+* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Deprecated the ``Features`` functionality.
+* `Issue #52 <https://bitbucket.org/pypa/setuptools/issue/52>`_: In ``VerifyingHTTPSConn``, handle a tunnelled (proxied)
+  connection.
+
+Backward-Incompatible Changes
+=============================
+
+This release includes a couple of backward-incompatible changes, but most if
+not all users will find 1.0 a drop-in replacement for 0.9.
+
+* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: Normalized API of environment marker support. Specifically,
+  removed line number and filename from SyntaxErrors when returned from
+  `pkg_resources.invalid_marker`. Any clients depending on the specific
+  string representation of exceptions returned by that function may need to
+  be updated to account for this change.
+* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: SyntaxErrors generated by `pkg_resources.invalid_marker` are
+  normalized for cross-implementation consistency.
+* Removed ``--ignore-conflicts-at-my-risk`` and ``--delete-conflicting``
+  options to easy_install. These options have been deprecated since 0.6a11.
+
+-----
+0.9.8
+-----
+
+* `Issue #53 <https://bitbucket.org/pypa/setuptools/issue/53>`_: Fix NameErrors in `_vcs_split_rev_from_url`.
+
+-----
+0.9.7
+-----
+
+* `Issue #49 <https://bitbucket.org/pypa/setuptools/issue/49>`_: Correct AttributeError on PyPy where a hashlib.HASH object does
+  not have a `.name` attribute.
+* `Issue #34 <https://bitbucket.org/pypa/setuptools/issue/34>`_: Documentation now refers to bootstrap script in code repository
+  referenced by bookmark.
+* Add underscore-separated keys to environment markers (markerlib).
+
+-----
+0.9.6
+-----
+
+* `Issue #44 <https://bitbucket.org/pypa/setuptools/issue/44>`_: Test failure on Python 2.4 when MD5 hash doesn't have a `.name`
+  attribute.
+
+-----
+0.9.5
+-----
+
+* `Python #17980 <http://bugs.python.org/issue17980>`_: Fix security vulnerability in SSL certificate validation.
+
+-----
+0.9.4
+-----
+
+* `Issue #43 <https://bitbucket.org/pypa/setuptools/issue/43>`_: Fix issue (introduced in 0.9.1) with version resolution when
+  upgrading over other releases of Setuptools.
+
+-----
+0.9.3
+-----
+
+* `Issue #42 <https://bitbucket.org/pypa/setuptools/issue/42>`_: Fix new ``AttributeError`` introduced in last fix.
+
+-----
+0.9.2
+-----
+
+* `Issue #42 <https://bitbucket.org/pypa/setuptools/issue/42>`_: Fix regression where blank checksums would trigger an
+  ``AttributeError``.
+
+-----
+0.9.1
+-----
+
+* `Distribute #386 <https://bitbucket.org/tarek/distribute/issue/386>`_: Allow other positional and keyword arguments to os.open.
+* Corrected dependency on certifi mis-referenced in 0.9.
+
+---
+0.9
+---
+
+* `package_index` now validates hashes other than MD5 in download links.
+
+---
+0.8
+---
+
+* Code base now runs on Python 2.4 - Python 3.3 without Python 2to3
+  conversion.
+
+-----
+0.7.8
+-----
+
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Yet another fix for yet another regression.
+
+-----
+0.7.7
+-----
+
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Repair AttributeError created in last release (redo).
+* `Issue #30 <https://bitbucket.org/pypa/setuptools/issue/30>`_: Added test for get_cache_path.

+
+* Merged Setuptools and Distribute. See docs/merge.txt for details.
+
+Added several features that were slated for setuptools 0.6c12:
+
+* Index URL now defaults to HTTPS.
+* Added experimental environment marker support. Now clients may designate a
+  PEP-426 environment marker for "extra" dependencies. Setuptools uses this
+  feature in ``setup.py`` for optional SSL and certificate validation support
+  on older platforms. Based on Distutils-SIG discussions, the syntax is
+  somewhat tentative. There should probably be a PEP with a firmer spec before
+  the feature should be considered suitable for use.
+* Added support for SSL certificate validation when installing packages from
+  an HTTPS service.

+  <http://technet.microsoft.com/en-us/library/cc709628%28WS.10%29.aspx>`_.

+  under Windows. Easy_install now skips all directories when processing
+  metadata scripts.
+
+------
+0.6.35

+* `Distribute #334 <https://bitbucket.org/tarek/distribute/issue/334>`_: Provide workaround for packages that reference `sys.__stdout__`
+  such as numpy does. This change should address
+  `virtualenv `#359 <https://bitbucket.org/pypa/setuptools/issue/359>`_ <https://github.com/pypa/virtualenv/issues/359>`_ as long
+  as the system encoding is UTF-8 or the IO encoding is specified in the
+  environment, i.e.::
+
+     PYTHONIOENCODING=utf8 pip install numpy
+
+* Fix for encoding issue when installing from Windows executable on Python 3.
+* `Distribute #323 <https://bitbucket.org/tarek/distribute/issue/323>`_: Allow `setup_requires` requirements to supercede installed
+  requirements. Added some new keyword arguments to existing pkg_resources
+  methods. Also had to updated how __path__ is handled for namespace packages
+  to ensure that when a new egg distribution containing a namespace package is
+  placed on sys.path, the entries in __path__ are found in the same order they
+  would have been in had that egg been on the path when pkg_resources was
+  first imported.

+* `Distribute #11 <https://bitbucket.org/tarek/distribute/issue/11>`_: Generated scripts now wrap their call to the script entry point
+  in the standard "if name == 'main'"
+* Added the 'DONT_PATCH_SETUPTOOLS' environment variable, so virtualenv
+  can drive an installation that doesn't patch a global setuptools.
+* Reviewed unladen-swallow specific change from
+  http://code.google.com/p/unladen-swallow/source/detail?spec=svn875&r=719
+  and determined that it no longer applies. Distribute should work fine with
+  Unladen Swallow 2009Q3.
+* `Distribute #21 <https://bitbucket.org/tarek/distribute/issue/21>`_: Allow PackageIndex.open_url to gracefully handle all cases of a
+  httplib.HTTPException instead of just InvalidURL and BadStatusLine.
+* Removed virtual-python.py from this distribution and updated documentation
+  to point to the actively maintained virtualenv instead.
+* `Distribute #64 <https://bitbucket.org/tarek/distribute/issue/64>`_: use_setuptools no longer rebuilds the distribute egg every
+  time it is run
+* use_setuptools now properly respects the requested version
+* use_setuptools will no longer try to import a distribute egg for the
+  wrong Python version
+* `Distribute #74 <https://bitbucket.org/tarek/distribute/issue/74>`_: no_fake should be True by default.
+* `Distribute #72 <https://bitbucket.org/tarek/distribute/issue/72>`_: avoid a bootstrapping issue with easy_install -U
+
+-----
+0.6.6

+
+* Unified the bootstrap file so it works on both py2.x and py3k without 2to3
+  (patch by Holger Krekel)
+
+-----
+0.6.5
+-----
+
+* `Distribute #65 <https://bitbucket.org/tarek/distribute/issue/65>`_: cli.exe and gui.exe are now generated at build time,
+  depending on the platform in use.
+
+* `Distribute #67 <https://bitbucket.org/tarek/distribute/issue/67>`_: Fixed doc typo (PEP 381/382)
+
+* Distribute no longer shadows setuptools if we require a 0.7-series
+  setuptools.  And an error is raised when installing a 0.7 setuptools with
+  distribute.
+
+* When run from within buildout, no attempt is made to modify an existing
+  setuptools egg, whether in a shared egg directory or a system setuptools.
+
+* Fixed a hole in sandboxing allowing builtin file to write outside of
+  the sandbox.
+
+-----
+0.6.4
+-----
+
+* Added the generation of `distribute_setup_3k.py` during the release.
+  This closes `Distribute #52 <https://bitbucket.org/tarek/distribute/issue/52>`_.

+
+-----
+0.6c9
+-----
+
+ * Fixed a missing files problem when using Windows source distributions on
+   non-Windows platforms, due to distutils not handling manifest file line
+   endings correctly.
+
+ * Updated Pyrex support to work with Pyrex 0.9.6 and higher.
+
+ * Minor changes for Jython compatibility, including skipping tests that can't
+   work on Jython.
+
+ * Fixed not installing eggs in ``install_requires`` if they were also used for
+   ``setup_requires`` or ``tests_require``.
+
+ * Fixed not fetching eggs in ``install_requires`` when running tests.
+
+ * Allow ``ez_setup.use_setuptools()`` to upgrade existing setuptools
+   installations when called from a standalone ``setup.py``.
+
+ * Added a warning if a namespace package is declared, but its parent package
+   is not also declared as a namespace.
+
+ * Support Subversion 1.5
+
+ * Removed use of deprecated ``md5`` module if ``hashlib`` is available
+
+ * Fixed ``bdist_wininst upload`` trying to upload the ``.exe`` twice
+
+ * Fixed ``bdist_egg`` putting a ``native_libs.txt`` in the source package's
+   ``.egg-info``, when it should only be in the built egg's ``EGG-INFO``.
+
+ * Ensure that _full_name is set on all shared libs before extensions are
+   checked for shared lib usage.  (Fixes a bug in the experimental shared
+   library build support.)
+
+ * Fix to allow unpacked eggs containing native libraries to fail more
+   gracefully under Google App Engine (with an ``ImportError`` loading the
+   C-based module, instead of getting a ``NameError``).
+
+-----
+0.6c7
+-----
+
+ * Fixed ``distutils.filelist.findall()`` crashing on broken symlinks, and
+   ``egg_info`` command failing on new, uncommitted SVN directories.
+
+ * Fix import problems with nested namespace packages installed via
+   ``--root`` or ``--single-version-externally-managed``, due to the
+   parent package not having the child package as an attribute.
+
+-----
+0.6c6
+-----
+
+ * Added ``--egg-path`` option to ``develop`` command, allowing you to force
+   ``.egg-link`` files to use relative paths (allowing them to be shared across
+   platforms on a networked drive).
+
+ * Fix not building binary RPMs correctly.
+
+ * Fix "eggsecutables" (such as setuptools' own egg) only being runnable with
+   bash-compatible shells.
+
+ * Fix ``#!`` parsing problems in Windows ``.exe`` script wrappers, when there
+   was whitespace inside a quoted argument or at the end of the ``#!`` line
+   (a regression introduced in 0.6c4).
+
+ * Fix ``test`` command possibly failing if an older version of the project
+   being tested was installed on ``sys.path`` ahead of the test source
+   directory.
+
+ * Fix ``find_packages()`` treating ``ez_setup`` and directories with ``.`` in
+   their names as packages.
+
+-----
+0.6c5
+-----
+
+ * Fix uploaded ``bdist_rpm`` packages being described as ``bdist_egg``
+   packages under Python versions less than 2.5.
+
+ * Fix uploaded ``bdist_wininst`` packages being described as suitable for
+   "any" version by Python 2.5, even if a ``--target-version`` was specified.
+
+-----
+0.6c4
+-----
+
+ * Overhauled Windows script wrapping to support ``bdist_wininst`` better.
+   Scripts installed with ``bdist_wininst`` will always use ``#!python.exe`` or
+   ``#!pythonw.exe`` as the executable name (even when built on non-Windows
+   platforms!), and the wrappers will look for the executable in the script's
+   parent directory (which should find the right version of Python).
+
+ * Fix ``upload`` command not uploading files built by ``bdist_rpm`` or
+   ``bdist_wininst`` under Python 2.3 and 2.4.
+
+ * Add support for "eggsecutable" headers: a ``#!/bin/sh`` script that is
+   prepended to an ``.egg`` file to allow it to be run as a script on Unix-ish
+   platforms.  (This is mainly so that setuptools itself can have a single-file
+   installer on Unix, without doing multiple downloads, dealing with firewalls,
+   etc.)
+
+ * Fix problem with empty revision numbers in Subversion 1.4 ``entries`` files
+
+ * Use cross-platform relative paths in ``easy-install.pth`` when doing
+   ``develop`` and the source directory is a subdirectory of the installation
+   target directory.
+
+ * Fix a problem installing eggs with a system packaging tool if the project
+   contained an implicit namespace package; for example if the ``setup()``
+   listed a namespace package ``foo.bar`` without explicitly listing ``foo``
+   as a namespace package.
+
+-----
+0.6c3
+-----
+
+ * Fixed breakages caused by Subversion 1.4's new "working copy" format
+
+-----
+0.6c2
+-----
+
+ * The ``ez_setup`` module displays the conflicting version of setuptools (and
+   its installation location) when a script requests a version that's not
+   available.
+
+ * Running ``setup.py develop`` on a setuptools-using project will now install
+   setuptools if needed, instead of only downloading the egg.
+
+-----
+0.6c1
+-----
+
+ * Fixed ``AttributeError`` when trying to download a ``setup_requires``
+   dependency when a distribution lacks a ``dependency_links`` setting.
+
+ * Made ``zip-safe`` and ``not-zip-safe`` flag files contain a single byte, so
+   as to play better with packaging tools that complain about zero-length
+   files.
+
+ * Made ``setup.py develop`` respect the ``--no-deps`` option, which it
+   previously was ignoring.
+
+ * Support ``extra_path`` option to ``setup()`` when ``install`` is run in
+   backward-compatibility mode.
+
+ * Source distributions now always include a ``setup.cfg`` file that explicitly
+   sets ``egg_info`` options such that they produce an identical version number
+   to the source distribution's version number.  (Previously, the default
+   version number could be different due to the use of ``--tag-date``, or if
+   the version was overridden on the command line that built the source
+   distribution.)
+
+-----
+0.6b4
+-----
+
+ * Fix ``register`` not obeying name/version set by ``egg_info`` command, if
+   ``egg_info`` wasn't explicitly run first on the same command line.
+
+ * Added ``--no-date`` and ``--no-svn-revision`` options to ``egg_info``
+   command, to allow suppressing tags configured in ``setup.cfg``.
+
+ * Fixed redundant warnings about missing ``README`` file(s); it should now
+   appear only if you are actually a source distribution.
+
+-----
+0.6b3
+-----
+
+ * Fix ``bdist_egg`` not including files in subdirectories of ``.egg-info``.
+
+ * Allow ``.py`` files found by the ``include_package_data`` option to be
+   automatically included.  Remove duplicate data file matches if both
+   ``include_package_data`` and ``package_data`` are used to refer to the same
+   files.
+
+-----
+0.6b1
+-----
+
+ * Strip ``module`` from the end of compiled extension modules when computing
+   the name of a ``.py`` loader/wrapper.  (Python's import machinery ignores
+   this suffix when searching for an extension module.)
+
+------
+0.6a11
+------
+
+ * Added ``test_loader`` keyword to support custom test loaders
+
+ * Added ``setuptools.file_finders`` entry point group to allow implementing
+   revision control plugins.
+
+ * Added ``--identity`` option to ``upload`` command.
+
+ * Added ``dependency_links`` to allow specifying URLs for ``--find-links``.
+
+ * Enhanced test loader to scan packages as well as modules, and call
+   ``additional_tests()`` if present to get non-unittest tests.
+
+ * Support namespace packages in conjunction with system packagers, by omitting
+   the installation of any ``__init__.py`` files for namespace packages, and
+   adding a special ``.pth`` file to create a working package in
+   ``sys.modules``.
+
+ * Made ``--single-version-externally-managed`` automatic when ``--root`` is
+   used, so that most system packagers won't require special support for
+   setuptools.
+
+ * Fixed ``setup_requires``, ``tests_require``, etc. not using ``setup.cfg`` or
+   other configuration files for their option defaults when installing, and
+   also made the install use ``--multi-version`` mode so that the project
+   directory doesn't need to support .pth files.
+
+ * ``MANIFEST.in`` is now forcibly closed when any errors occur while reading
+   it.  Previously, the file could be left open and the actual error would be
+   masked by problems trying to remove the open file on Windows systems.
+
+------
+0.6a10
+------
+
+ * Fixed the ``develop`` command ignoring ``--find-links``.
+
+-----
+0.6a9
+-----
+
+ * The ``sdist`` command no longer uses the traditional ``MANIFEST`` file to
+   create source distributions.  ``MANIFEST.in`` is still read and processed,
+   as are the standard defaults and pruning.  But the manifest is built inside
+   the project's ``.egg-info`` directory as ``SOURCES.txt``, and it is rebuilt
+   every time the ``egg_info`` command is run.
+
+ * Added the ``include_package_data`` keyword to ``setup()``, allowing you to
+   automatically include any package data listed in revision control or
+   ``MANIFEST.in``
+
+ * Added the ``exclude_package_data`` keyword to ``setup()``, allowing you to
+   trim back files included via the ``package_data`` and
+   ``include_package_data`` options.
+
+ * Fixed ``--tag-svn-revision`` not working when run from a source
+   distribution.
+
+ * Added warning for namespace packages with missing ``declare_namespace()``
+
+ * Added ``tests_require`` keyword to ``setup()``, so that e.g. packages
+   requiring ``nose`` to run unit tests can make this dependency optional
+   unless the ``test`` command is run.
+
+ * Made all commands that use ``easy_install`` respect its configuration
+   options, as this was causing some problems with ``setup.py install``.
+
+ * Added an ``unpack_directory()`` driver to ``setuptools.archive_util``, so
+   that you can process a directory tree through a processing filter as if it
+   were a zipfile or tarfile.
+
+ * Added an internal ``install_egg_info`` command to use as part of old-style
+   ``install`` operations, that installs an ``.egg-info`` directory with the
+   package.
+
+ * Added a ``--single-version-externally-managed`` option to the ``install``
+   command so that you can more easily wrap a "flat" egg in a system package.
+
+ * Enhanced ``bdist_rpm`` so that it installs single-version eggs that
+   don't rely on a ``.pth`` file.  The ``--no-egg`` option has been removed,
+   since all RPMs are now built in a more backwards-compatible format.
+
+ * Support full roundtrip translation of eggs to and from ``bdist_wininst``
+   format.  Running ``bdist_wininst`` on a setuptools-based package wraps the
+   egg in an .exe that will safely install it as an egg (i.e., with metadata
+   and entry-point wrapper scripts), and ``easy_install`` can turn the .exe
+   back into an ``.egg`` file or directory and install it as such.
+
+
+-----
+0.6a8
+-----
+
+ * Fixed some problems building extensions when Pyrex was installed, especially
+   with Python 2.4 and/or packages using SWIG.
+
+ * Made ``develop`` command accept all the same options as ``easy_install``,
+   and use the ``easy_install`` command's configuration settings as defaults.
+
+ * Made ``egg_info --tag-svn-revision`` fall back to extracting the revision
+   number from ``PKG-INFO`` in case it is being run on a source distribution of
+   a snapshot taken from a Subversion-based project.
+
+ * Automatically detect ``.dll``, ``.so`` and ``.dylib`` files that are being
+   installed as data, adding them to ``native_libs.txt`` automatically.
+
+ * Fixed some problems with fresh checkouts of projects that don't include
+   ``.egg-info/PKG-INFO`` under revision control and put the project's source
+   code directly in the project directory.  If such a package had any
+   requirements that get processed before the ``egg_info`` command can be run,
+   the setup scripts would fail with a "Missing 'Version:' header and/or
+   PKG-INFO file" error, because the egg runtime interpreted the unbuilt
+   metadata in a directory on ``sys.path`` (i.e. the current directory) as
+   being a corrupted egg.  Setuptools now monkeypatches the distribution
+   metadata cache to pretend that the egg has valid version information, until
+   it has a chance to make it actually be so (via the ``egg_info`` command).
+
+-----
+0.6a5
+-----
+
+ * Fixed missing gui/cli .exe files in distribution.  Fixed bugs in tests.
+
+-----
+0.6a3
+-----
+
+ * Added ``gui_scripts`` entry point group to allow installing GUI scripts
+   on Windows and other platforms.  (The special handling is only for Windows;
+   other platforms are treated the same as for ``console_scripts``.)
+
+-----
+0.6a2
+-----
+
+ * Added ``console_scripts`` entry point group to allow installing scripts
+   without the need to create separate script files.  On Windows, console
+   scripts get an ``.exe`` wrapper so you can just type their name.  On other
+   platforms, the scripts are written without a file extension.
+
+-----
+0.6a1
+-----
+
+ * Added support for building "old-style" RPMs that don't install an egg for
+   the target package, using a ``--no-egg`` option.
+
+ * The ``build_ext`` command now works better when using the ``--inplace``
+   option and multiple Python versions.  It now makes sure that all extensions
+   match the current Python version, even if newer copies were built for a
+   different Python version.
+
+ * The ``upload`` command no longer attaches an extra ``.zip`` when uploading
+   eggs, as PyPI now supports egg uploads without trickery.
+
+ * The ``ez_setup`` script/module now displays a warning before downloading
+   the setuptools egg, and attempts to check the downloaded egg against an
+   internal MD5 checksum table.
+
+ * Fixed the ``--tag-svn-revision`` option of ``egg_info`` not finding the
+   latest revision number; it was using the revision number of the directory
+   containing ``setup.py``, not the highest revision number in the project.
+
+ * Added ``eager_resources`` setup argument
+
+ * The ``sdist`` command now recognizes Subversion "deleted file" entries and
+   does not include them in source distributions.
+
+ * ``setuptools`` now embeds itself more thoroughly into the distutils, so that
+   other distutils extensions (e.g. py2exe, py2app) will subclass setuptools'
+   versions of things, rather than the native distutils ones.
+
+ * Added ``entry_points`` and ``setup_requires`` arguments to ``setup()``;
+   ``setup_requires`` allows you to automatically find and download packages
+   that are needed in order to *build* your project (as opposed to running it).
+
+ * ``setuptools`` now finds its commands, ``setup()`` argument validators, and
+   metadata writers using entry points, so that they can be extended by
+   third-party packages.  See `Creating distutils Extensions
+   <http://pythonhosted.org/setuptools/setuptools.html#creating-distutils-extensions>`_
+   for more details.
+
+ * The vestigial ``depends`` command has been removed.  It was never finished
+   or documented, and never would have worked without EasyInstall - which it
+   pre-dated and was never compatible with.
+
+------
+0.5a12
+------
+
+ * The zip-safety scanner now checks for modules that might be used with
+   ``python -m``, and marks them as unsafe for zipping, since Python 2.4 can't
+   handle ``-m`` on zipped modules.
+
+------
+0.5a11
+------
+
+ * Fix breakage of the "develop" command that was caused by the addition of
+   ``--always-unzip`` to the ``easy_install`` command.
+
+-----
+0.5a9
+-----
+
+ * Include ``svn:externals`` directories in source distributions as well as
+   normal subversion-controlled files and directories.
+
+ * Added ``exclude=patternlist`` option to ``setuptools.find_packages()``
+
+ * Changed --tag-svn-revision to include an "r" in front of the revision number
+   for better readability.
+
+ * Added ability to build eggs without including source files (except for any
+   scripts, of course), using the ``--exclude-source-files`` option to
+   ``bdist_egg``.
+
+ * ``setup.py install`` now automatically detects when an "unmanaged" package
+   or module is going to be on ``sys.path`` ahead of a package being installed,
+   thereby preventing the newer version from being imported.  If this occurs,
+   a warning message is output to ``sys.stderr``, but installation proceeds
+   anyway.  The warning message informs the user what files or directories
+   need deleting, and advises them they can also use EasyInstall (with the
+   ``--delete-conflicting`` option) to do it automatically.
+
+ * The ``egg_info`` command now adds a ``top_level.txt`` file to the metadata
+   directory that lists all top-level modules and packages in the distribution.
+   This is used by the ``easy_install`` command to find possibly-conflicting
+   "unmanaged" packages when installing the distribution.
+
+ * Added ``zip_safe`` and ``namespace_packages`` arguments to ``setup()``.
+   Added package analysis to determine zip-safety if the ``zip_safe`` flag
+   is not given, and advise the author regarding what code might need changing.
+
+ * Fixed the swapped ``-d`` and ``-b`` options of ``bdist_egg``.
+
+-----
+0.5a8
+-----
+
+ * The "egg_info" command now always sets the distribution metadata to "safe"
+   forms of the distribution name and version, so that distribution files will
+   be generated with parseable names (i.e., ones that don't include '-' in the
+   name or version).  Also, this means that if you use the various ``--tag``
+   options of "egg_info", any distributions generated will use the tags in the
+   version, not just egg distributions.
+
+ * Added support for defining command aliases in distutils configuration files,
+   under the "[aliases]" section.  To prevent recursion and to allow aliases to
+   call the command of the same name, a given alias can be expanded only once
+   per command-line invocation.  You can define new aliases with the "alias"
+   command, either for the local, global, or per-user configuration.
+
+ * Added "rotate" command to delete old distribution files, given a set of
+   patterns to match and the number of files to keep.  (Keeps the most
+   recently-modified distribution files matching each pattern.)
+
+ * Added "saveopts" command that saves all command-line options for the current
+   invocation to the local, global, or per-user configuration file.  Useful for
+   setting defaults without having to hand-edit a configuration file.
+
+ * Added a "setopt" command that sets a single option in a specified distutils
+   configuration file.
+
+-----
+0.5a7

+
+ * Added "upload" support for egg and source distributions, including a bug
+   fix for "upload" and a temporary workaround for lack of .egg support in
+   PyPI.
+
+-----
+0.5a6
+-----
+
+ * Beefed up the "sdist" command so that if you don't have a MANIFEST.in, it
+   will include all files under revision control (CVS or Subversion) in the
+   current directory, and it will regenerate the list every time you create a
+   source distribution, not just when you tell it to.  This should make the
+   default "do what you mean" more often than the distutils' default behavior
+   did, while still retaining the old behavior in the presence of MANIFEST.in.
+
+ * Fixed the "develop" command always updating .pth files, even if you
+   specified ``-n`` or ``--dry-run``.
+
+ * Slightly changed the format of the generated version when you use
+   ``--tag-build`` on the "egg_info" command, so that you can make tagged
+   revisions compare *lower* than the version specified in setup.py (e.g. by
+   using ``--tag-build=dev``).
+
+-----
+0.5a5
+-----
+
+ * Added ``develop`` command to ``setuptools``-based packages.  This command
+   installs an ``.egg-link`` pointing to the package's source directory, and
+   script wrappers that ``execfile()`` the source versions of the package's
+   scripts.  This lets you put your development checkout(s) on sys.path without
+   having to actually install them.  (To uninstall the link, use
+   use ``setup.py develop --uninstall``.)
+
+ * Added ``egg_info`` command to ``setuptools``-based packages.  This command
+   just creates or updates the "projectname.egg-info" directory, without
+   building an egg.  (It's used by the ``bdist_egg``, ``test``, and ``develop``
+   commands.)
+
+ * Enhanced the ``test`` command so that it doesn't install the package, but
+   instead builds any C extensions in-place, updates the ``.egg-info``
+   metadata, adds the source directory to ``sys.path``, and runs the tests
+   directly on the source.  This avoids an "unmanaged" installation of the
+   package to ``site-packages`` or elsewhere.
+
+ * Made ``easy_install`` a standard ``setuptools`` command, moving it from
+   the ``easy_install`` module to ``setuptools.command.easy_install``.  Note
+   that if you were importing or extending it, you must now change your imports
+   accordingly.  ``easy_install.py`` is still installed as a script, but not as
+   a module.
+
+-----
+0.5a4
+-----
+
+ * Setup scripts using setuptools can now list their dependencies directly in
+   the setup.py file, without having to manually create a ``depends.txt`` file.
+   The ``install_requires`` and ``extras_require`` arguments to ``setup()``
+   are used to create a dependencies file automatically.  If you are manually
+   creating ``depends.txt`` right now, please switch to using these setup
+   arguments as soon as practical, because ``depends.txt`` support will be
+   removed in the 0.6 release cycle.  For documentation on the new arguments,
+   see the ``setuptools.dist.Distribution`` class.
+
+ * Setup scripts using setuptools now always install using ``easy_install``
+   internally, for ease of uninstallation and upgrading.
+
+-----
+0.5a1
+-----
+
+ * Added support for "self-installation" bootstrapping.  Packages can now
+   include ``ez_setup.py`` in their source distribution, and add the following
+   to their ``setup.py``, in order to automatically bootstrap installation of
+   setuptools as part of their setup process::
+
+    from ez_setup import use_setuptools
+    use_setuptools()
+
+    from setuptools import setup
+    # etc...
+
+-----
+0.4a2
+-----
+
+ * Added ``ez_setup.py`` installer/bootstrap script to make initial setuptools
+   installation easier, and to allow distributions using setuptools to avoid
+   having to include setuptools in their source distribution.
+
+ * All downloads are now managed by the ``PackageIndex`` class (which is now
+   subclassable and replaceable), so that embedders can more easily override
+   download logic, give download progress reports, etc.  The class has also
+   been moved to the new ``setuptools.package_index`` module.
+
+ * The ``Installer`` class no longer handles downloading, manages a temporary
+   directory, or tracks the ``zip_ok`` option.  Downloading is now handled
+   by ``PackageIndex``, and ``Installer`` has become an ``easy_install``
+   command class based on ``setuptools.Command``.
+
+ * There is a new ``setuptools.sandbox.run_setup()`` API to invoke a setup
+   script in a directory sandbox, and a new ``setuptools.archive_util`` module
+   with an ``unpack_archive()`` API.  These were split out of EasyInstall to
+   allow reuse by other tools and applications.
+
+ * ``setuptools.Command`` now supports reinitializing commands using keyword
+   arguments to set/reset options.  Also, ``Command`` subclasses can now set
+   their ``command_consumes_arguments`` attribute to ``True`` in order to
+   receive an ``args`` option containing the rest of the command line.
+
+-----
+0.3a2
+-----
+
+ * Added new options to ``bdist_egg`` to allow tagging the egg's version number
+   with a subversion revision number, the current date, or an explicit tag
+   value.  Run ``setup.py bdist_egg --help`` to get more information.
+
+ * Misc. bug fixes
+
+-----
+0.3a1
+-----
+
+ * Initial release.

+===============================
+Installing and Using Setuptools
+===============================
+
+.. contents:: **Table of Contents**
+
+
+-------------------------
+Installation Instructions
+-------------------------
+
+Upgrading from Distribute
+=========================
+
+Currently, Distribute disallows installing Setuptools 0.7+ over Distribute.
+You must first uninstall any active version of Distribute first (see
+`Uninstalling`_).
+
+Upgrading from Setuptools 0.6
+=============================
+
+Upgrading from prior versions of Setuptools is supported. Initial reports
+good success in this regard.
+
+Windows
+=======
+
+The recommended way to install setuptools on Windows is to download
+`ez_setup.py`_ and run it. The script will download the appropriate .egg
+file and install it for you.
+
+.. _ez_setup.py: https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py
+
+For best results, uninstall previous versions FIRST (see `Uninstalling`_).
+
+Once installation is complete, you will find an ``easy_install`` program in
+your Python ``Scripts`` subdirectory.  For simple invocation and best results,
+add this directory to your ``PATH`` environment variable, if it is not already
+present.
+
+
+Unix-based Systems including Mac OS X
+=====================================
+
+Download `ez_setup.py`_ and run it using the target Python version. The script
+will download the appropriate version and install it for you::
+
+    > wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | python
+
+Note that you will may need to invoke the command with superuser privileges to
+install to the system Python::
+
+    > wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | sudo python
+
+Alternatively, on Python 2.6 and later, Setuptools may be installed to a
+user-local path::
+
+    > wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py
+    > python ez_setup.py --user
+
+
+Python 2.4 and Python 2.5 support
+=================================
+
+Setuptools 2.0 and later requires Python 2.6 or later. To install setuptools
+on Python 2.4 or Python 2.5, use the bootstrap script for Setuptools 1.x:
+https://bitbucket.org/pypa/setuptools/raw/bootstrap-py24/ez_setup.py.
+
+
+Advanced Installation
+=====================
+
+For more advanced installation options, such as installing to custom
+locations or prefixes, download and extract the source
+tarball from `Setuptools on PyPI <https://pypi.python.org/pypi/setuptools>`_
+and run setup.py with any supported distutils and Setuptools options.
+For example::
+
+    setuptools-x.x$ python setup.py --prefix=/opt/setuptools
+
+Use ``--help`` to get a full options list, but we recommend consulting
+the `EasyInstall manual`_ for detailed instructions, especially `the section
+on custom installation locations`_.
+
+.. _EasyInstall manual: https://pythonhosted.org/setuptools/EasyInstall
+.. _the section on custom installation locations: https://pythonhosted.org/setuptools/EasyInstall#custom-installation-locations
+
+
+Downloads
+=========
+
+All setuptools downloads can be found at `the project's home page in the Python
+Package Index`_.  Scroll to the very bottom of the page to find the links.
+
+.. _the project's home page in the Python Package Index: https://pypi.python.org/pypi/setuptools
+
+In addition to the PyPI downloads, the development version of ``setuptools``
+is available from the `Bitbucket repo`_, and in-development versions of the
+`0.6 branch`_ are available as well.
+
+.. _Bitbucket repo: https://bitbucket.org/pypa/setuptools/get/default.tar.gz#egg=setuptools-dev
+.. _0.6 branch: http://svn.python.org/projects/sandbox/branches/setuptools-0.6/#egg=setuptools-dev06
+
+Uninstalling
+============
+
+On Windows, if Setuptools was installed using an ``.exe`` or ``.msi``
+installer, simply use the uninstall feature of "Add/Remove Programs" in the
+Control Panel.
+
+Otherwise, to uninstall Setuptools or Distribute, regardless of the Python
+version, delete all ``setuptools*`` and ``distribute*`` files and
+directories from your system's ``site-packages`` directory
+(and any other ``sys.path`` directories) FIRST.
+
+If you are upgrading or otherwise plan to re-install Setuptools or Distribute,
+nothing further needs to be done. If you want to completely remove Setuptools,
+you may also want to remove the 'easy_install' and 'easy_install-x.x' scripts
+and associated executables installed to the Python scripts directory.
+
+--------------------------------
+Using Setuptools and EasyInstall
+--------------------------------
+
+Here are some of the available manuals, tutorials, and other resources for
+learning about Setuptools, Python Eggs, and EasyInstall:
+
+* `The EasyInstall user's guide and reference manual`_
+* `The setuptools Developer's Guide`_
+* `The pkg_resources API reference`_
+* `Package Compatibility Notes`_ (user-maintained)
+* `The Internal Structure of Python Eggs`_
+
+Questions, comments, and bug reports should be directed to the `distutils-sig
+mailing list`_.  If you have written (or know of) any tutorials, documentation,
+plug-ins, or other resources for setuptools users, please let us know about
+them there, so this reference list can be updated.  If you have working,
+*tested* patches to correct problems or add features, you may submit them to
+the `setuptools bug tracker`_.

+Credits
+-------
+
+* The original design for the ``.egg`` format and the ``pkg_resources`` API was
+  co-created by Phillip Eby and Bob Ippolito.  Bob also implemented the first
+  version of ``pkg_resources``, and supplied the OS X operating system version
+  compatibility algorithm.
+
+* Ian Bicking implemented many early "creature comfort" features of
+  easy_install, including support for downloading via Sourceforge and
+  Subversion repositories.  Ian's comments on the Web-SIG about WSGI
+  application deployment also inspired the concept of "entry points" in eggs,
+  and he has given talks at PyCon and elsewhere to inform and educate the
+  community about eggs and setuptools.
+
+* Jim Fulton contributed time and effort to build automated tests of various
+  aspects of ``easy_install``, and supplied the doctests for the command-line
+  ``.exe`` wrappers on Windows.
+
+* Phillip J. Eby is the seminal author of setuptools, and
+  first proposed the idea of an importable binary distribution format for
+  Python application plug-ins.
+
+* Significant parts of the implementation of setuptools were funded by the Open
+  Source Applications Foundation, to provide a plug-in infrastructure for the
+  Chandler PIM application.  In addition, many OSAF staffers (such as Mike
+  "Code Bear" Taylor) contributed their time and stress as guinea pigs for the
+  use of eggs and setuptools, even before eggs were "cool".  (Thanks, guys!)
+
+* Since the merge with Distribute, Jason R. Coombs is the
+  maintainer of setuptools.  The project is maintained in coordination with
+  the Python Packaging Authority (PyPA) and the larger Python community.

+  in a zip-imported file.
+* `Issue #131 <https://bitbucket.org/pypa/setuptools/issue/131>`_: Fix RuntimeError when constructing an egg fetcher.
+
+-----
+2.0.2
+-----
+
+* Fix NameError during installation with Python implementations (e.g. Jython)
+  not containing parser module.
+* Fix NameError in ``sdist:re_finder``.
+
+-----
+2.0.1
+-----
+
+* `Issue #124 <https://bitbucket.org/pypa/setuptools/issue/124>`_: Fixed error in list detection in upload_docs.
+
+---
+2.0
+---
+
+* `Issue #121 <https://bitbucket.org/pypa/setuptools/issue/121>`_: Exempt lib2to3 pickled grammars from DirectorySandbox.
+* `Issue #41 <https://bitbucket.org/pypa/setuptools/issue/41>`_: Dropped support for Python 2.4 and Python 2.5. Clients requiring
+  setuptools for those versions of Python should use setuptools 1.x.
+* Removed ``setuptools.command.easy_install.HAS_USER_SITE``. Clients
+  expecting this boolean variable should use ``site.ENABLE_USER_SITE``
+  instead.
+* Removed ``pkg_resources.ImpWrapper``. Clients that expected this class
+  should use ``pkgutil.ImpImporter`` instead.
+
+-----
+1.4.2
+-----
+
+* `Issue #116 <https://bitbucket.org/pypa/setuptools/issue/116>`_: Correct TypeError when reading a local package index on Python
+  3.
+
+-----
+1.4.1
+-----
+
+* `Issue #114 <https://bitbucket.org/pypa/setuptools/issue/114>`_: Use ``sys.getfilesystemencoding`` for decoding config in
+  ``bdist_wininst`` distributions.
+
+* `Issue #105 <https://bitbucket.org/pypa/setuptools/issue/105>`_ and `Issue #113 <https://bitbucket.org/pypa/setuptools/issue/113>`_: Establish a more robust technique for
+  determining the terminal encoding::
+
+    1. Try ``getpreferredencoding``
+    2. If that returns US_ASCII or None, try the encoding from
+       ``getdefaultlocale``. If that encoding was a "fallback" because Python
+       could not figure it out from the environment or OS, encoding remains
+       unresolved.
+    3. If the encoding is resolved, then make sure Python actually implements
+       the encoding.
+    4. On the event of an error or unknown codec, revert to fallbacks
+       (UTF-8 on Darwin, ASCII on everything else).
+    5. On the encoding is 'mac-roman' on Darwin, use UTF-8 as 'mac-roman' was
+       a bug on older Python releases.
+
+    On a side note, it would seem that the encoding only matters for when SVN
+    does not yet support ``--xml`` and when getting repository and svn version
+    numbers. The ``--xml`` technique should yield UTF-8 according to some
+    messages on the SVN mailing lists. So if the version numbers are always
+    7-bit ASCII clean, it may be best to only support the file parsing methods
+    for legacy SVN releases and support for SVN without the subprocess command
+    would simple go away as support for the older SVNs does.
+
+---
+1.4
+---
+
+* `Issue #27 <https://bitbucket.org/pypa/setuptools/issue/27>`_: ``easy_install`` will now use credentials from .pypirc if
+  present for connecting to the package index.
+* `Pull Request #21 <https://bitbucket.org/pypa/setuptools/pull-request/21>`_: Omit unwanted newlines in ``package_index._encode_auth``
+  when the username/password pair length indicates wrapping.
+
+-----
+1.3.2
+-----
+
+* `Issue #99 <https://bitbucket.org/pypa/setuptools/issue/99>`_: Fix filename encoding issues in SVN support.
+
+-----
+1.3.1
+-----
+
+* Remove exuberant warning in SVN support when SVN is not used.
+
+---
+1.3
+---
+
+* Address security vulnerability in SSL match_hostname check as reported in
+  `Python #17997 <http://bugs.python.org/issue17997>`_.
+* Prefer `backports.ssl_match_hostname
+  <https://pypi.python.org/pypi/backports.ssl_match_hostname>`_ for backport
+  implementation if present.

+
+---
+1.2
+---
+
+* `Issue #26 <https://bitbucket.org/pypa/setuptools/issue/26>`_: Add support for SVN 1.7. Special thanks to Philip Thiem for the
+  contribution.
+* `Issue #93 <https://bitbucket.org/pypa/setuptools/issue/93>`_: Wheels are now distributed with every release. Note that as
+  reported in `Issue #108 <https://bitbucket.org/pypa/setuptools/issue/108>`_, as of Pip 1.4, scripts aren't installed properly
+  from wheels. Therefore, if using Pip to install setuptools from a wheel,
+  the ``easy_install`` command will not be available.
+* Setuptools "natural" launcher support, introduced in 1.0, is now officially
+  supported.
+
+-----
+1.1.7
+-----
+
+* Fixed behavior of NameError handling in 'script template (dev).py' (script
+  launcher for 'develop' installs).
+* ``ez_setup.py`` now ensures partial downloads are cleaned up following
+  a failed download.
+* `Distribute #363 <https://bitbucket.org/tarek/distribute/issue/363>`_ and `Issue #55 <https://bitbucket.org/pypa/setuptools/issue/55>`_: Skip an sdist test that fails on locales
+  other than UTF-8.
+
+-----
+1.1.6
+-----
+
+* `Distribute #349 <https://bitbucket.org/tarek/distribute/issue/349>`_: ``sandbox.execfile`` now opens the target file in binary
+  mode, thus honoring a BOM in the file when compiled.
+
+-----
+1.1.5
+-----
+
+* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Second attempt at fix (logic was reversed).
+
+-----
+1.1.4
+-----
+
+* `Issue #77 <https://bitbucket.org/pypa/setuptools/issue/77>`_: Fix error in upload command (Python 2.4).
+
+-----
+1.1.3
+-----
+
+* Fix NameError in previous patch.
+
+-----
+1.1.2
+-----
+
+* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Correct issue where 404 errors are returned for URLs with
+  fragments in them (such as #egg=).
+
+-----
+1.1.1
+-----
+
+* `Issue #75 <https://bitbucket.org/pypa/setuptools/issue/75>`_: Add ``--insecure`` option to ez_setup.py to accommodate
+  environments where a trusted SSL connection cannot be validated.
+* `Issue #76 <https://bitbucket.org/pypa/setuptools/issue/76>`_: Fix AttributeError in upload command with Python 2.4.
+
+---
+1.1
+---
+
+* `Issue #71 <https://bitbucket.org/pypa/setuptools/issue/71>`_ (`Distribute #333 <https://bitbucket.org/tarek/distribute/issue/333>`_): EasyInstall now puts less emphasis on the
+  condition when a host is blocked via ``--allow-hosts``.
+* `Issue #72 <https://bitbucket.org/pypa/setuptools/issue/72>`_: Restored Python 2.4 compatibility in ``ez_setup.py``.
+
+---
+1.0
+---
+
+* `Issue #60 <https://bitbucket.org/pypa/setuptools/issue/60>`_: On Windows, Setuptools supports deferring to another launcher,
+  such as Vinay Sajip's `pylauncher <https://bitbucket.org/pypa/pylauncher>`_
+  (included with Python 3.3) to launch console and GUI scripts and not install
+  its own launcher executables. This experimental functionality is currently
+  only enabled if  the ``SETUPTOOLS_LAUNCHER`` environment variable is set to
+  "natural". In the future, this behavior may become default, but only after
+  it has matured and seen substantial adoption. The ``SETUPTOOLS_LAUNCHER``
+  also accepts "executable" to force the default behavior of creating launcher
+  executables.
+* `Issue #63 <https://bitbucket.org/pypa/setuptools/issue/63>`_: Bootstrap script (ez_setup.py) now prefers Powershell, curl, or
+  wget for retrieving the Setuptools tarball for improved security of the
+  install. The script will still fall back to a simple ``urlopen`` on
+  platforms that do not have these tools.
+* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Deprecated the ``Features`` functionality.
+* `Issue #52 <https://bitbucket.org/pypa/setuptools/issue/52>`_: In ``VerifyingHTTPSConn``, handle a tunnelled (proxied)
+  connection.
+
+Backward-Incompatible Changes
+=============================
+
+This release includes a couple of backward-incompatible changes, but most if
+not all users will find 1.0 a drop-in replacement for 0.9.
+
+* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: Normalized API of environment marker support. Specifically,
+  removed line number and filename from SyntaxErrors when returned from
+  `pkg_resources.invalid_marker`. Any clients depending on the specific
+  string representation of exceptions returned by that function may need to
+  be updated to account for this change.
+* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: SyntaxErrors generated by `pkg_resources.invalid_marker` are
+  normalized for cross-implementation consistency.
+* Removed ``--ignore-conflicts-at-my-risk`` and ``--delete-conflicting``
+  options to easy_install. These options have been deprecated since 0.6a11.
+
+-----
+0.9.8
+-----
+
+* `Issue #53 <https://bitbucket.org/pypa/setuptools/issue/53>`_: Fix NameErrors in `_vcs_split_rev_from_url`.
+
+-----
+0.9.7
+-----
+
+* `Issue #49 <https://bitbucket.org/pypa/setuptools/issue/49>`_: Correct AttributeError on PyPy where a hashlib.HASH object does
+  not have a `.name` attribute.
+* `Issue #34 <https://bitbucket.org/pypa/setuptools/issue/34>`_: Documentation now refers to bootstrap script in code repository
+  referenced by bookmark.
+* Add underscore-separated keys to environment markers (markerlib).
+
+-----
+0.9.6
+-----
+
+* `Issue #44 <https://bitbucket.org/pypa/setuptools/issue/44>`_: Test failure on Python 2.4 when MD5 hash doesn't have a `.name`
+  attribute.
+
+-----
+0.9.5
+-----
+
+* `Python #17980 <http://bugs.python.org/issue17980>`_: Fix security vulnerability in SSL certificate validation.
+
+-----
+0.9.4
+-----
+
+* `Issue #43 <https://bitbucket.org/pypa/setuptools/issue/43>`_: Fix issue (introduced in 0.9.1) with version resolution when
+  upgrading over other releases of Setuptools.
+
+-----
+0.9.3
+-----
+
+* `Issue #42 <https://bitbucket.org/pypa/setuptools/issue/42>`_: Fix new ``AttributeError`` introduced in last fix.
+
+-----
+0.9.2
+-----
+
+* `Issue #42 <https://bitbucket.org/pypa/setuptools/issue/42>`_: Fix regression where blank checksums would trigger an
+  ``AttributeError``.

+Added several features that were slated for setuptools 0.6c12:
+
+* Index URL now defaults to HTTPS.

+  PEP-426 environment marker for "extra" dependencies. Setuptools uses this
+  feature in ``setup.py`` for optional SSL and certificate validation support
+  on older platforms. Based on Distutils-SIG discussions, the syntax is
+  somewhat tentative. There should probably be a PEP with a firmer spec before
+  the feature should be considered suitable for use.
+* Added support for SSL certificate validation when installing packages from
+  an HTTPS service.

+  as the system encoding is UTF-8 or the IO encoding is specified in the
+  environment, i.e.::
+
+     PYTHONIOENCODING=utf8 pip install numpy
+
+* Fix for encoding issue when installing from Windows executable on Python 3.
+* `Distribute #323 <https://bitbucket.org/tarek/distribute/issue/323>`_: Allow `setup_requires` requirements to supercede installed
+  requirements. Added some new keyword arguments to existing pkg_resources
+  methods. Also had to updated how __path__ is handled for namespace packages
+  to ensure that when a new egg distribution containing a namespace package is
+  placed on sys.path, the entries in __path__ are found in the same order they
+  would have been in had that egg been on the path when pkg_resources was
+  first imported.

+* `Distribute #92 <https://bitbucket.org/tarek/distribute/issue/92>`_: Fixed the "no eggs" found error with MacPort
+  (platform.mac_ver() fails)
+* `Distribute #103 <https://bitbucket.org/tarek/distribute/issue/103>`_: test_get_script_header_jython_workaround not run
+  anymore under py3 with C or POSIX local. Contributed by Arfrever.
+* `Distribute #104 <https://bitbucket.org/tarek/distribute/issue/104>`_: remvoved the assertion when the installation fails,
+  with a nicer message for the end user.
+* `Distribute #100 <https://bitbucket.org/tarek/distribute/issue/100>`_: making sure there's no SandboxViolation when
+  the setup script patches setuptools.
+
+-----
+0.6.8
+-----
+
+* Added "check_packages" in dist. (added in Setuptools 0.6c11)
+* Fixed the DONT_PATCH_SETUPTOOLS state.
+
+-----
+0.6.7
+-----
+
+* `Distribute #58 <https://bitbucket.org/tarek/distribute/issue/58>`_: Added --user support to the develop command
+* `Distribute #11 <https://bitbucket.org/tarek/distribute/issue/11>`_: Generated scripts now wrap their call to the script entry point
+  in the standard "if name == 'main'"
+* Added the 'DONT_PATCH_SETUPTOOLS' environment variable, so virtualenv
+  can drive an installation that doesn't patch a global setuptools.
+* Reviewed unladen-swallow specific change from
+  http://code.google.com/p/unladen-swallow/source/detail?spec=svn875&r=719
+  and determined that it no longer applies. Distribute should work fine with
+  Unladen Swallow 2009Q3.
+* `Distribute #21 <https://bitbucket.org/tarek/distribute/issue/21>`_: Allow PackageIndex.open_url to gracefully handle all cases of a
+  httplib.HTTPException instead of just InvalidURL and BadStatusLine.
+* Removed virtual-python.py from this distribution and updated documentation
+  to point to the actively maintained virtualenv instead.
+* `Distribute #64 <https://bitbucket.org/tarek/distribute/issue/64>`_: use_setuptools no longer rebuilds the distribute egg every
+  time it is run
+* use_setuptools now properly respects the requested version
+* use_setuptools will no longer try to import a distribute egg for the
+  wrong Python version
+* `Distribute #74 <https://bitbucket.org/tarek/distribute/issue/74>`_: no_fake should be True by default.
+* `Distribute #72 <https://bitbucket.org/tarek/distribute/issue/72>`_: avoid a bootstrapping issue with easy_install -U
+
+-----
+0.6.6
+-----
+
+* Unified the bootstrap file so it works on both py2.x and py3k without 2to3
+  (patch by Holger Krekel)
+
+-----
+0.6.5
+-----
+
+* `Distribute #65 <https://bitbucket.org/tarek/distribute/issue/65>`_: cli.exe and gui.exe are now generated at build time,
+  depending on the platform in use.
+
+* `Distribute #67 <https://bitbucket.org/tarek/distribute/issue/67>`_: Fixed doc typo (PEP 381/382)
+
+* Distribute no longer shadows setuptools if we require a 0.7-series
+  setuptools.  And an error is raised when installing a 0.7 setuptools with
+  distribute.
+
+* When run from within buildout, no attempt is made to modify an existing
+  setuptools egg, whether in a shared egg directory or a system setuptools.
+
+* Fixed a hole in sandboxing allowing builtin file to write outside of
+  the sandbox.
+
+-----
+0.6.4
+-----
+
+* Added the generation of `distribute_setup_3k.py` during the release.
+  This closes `Distribute #52 <https://bitbucket.org/tarek/distribute/issue/52>`_.
+
+* Added an upload_docs command to easily upload project documentation to
+  PyPI's https://pythonhosted.org. This close issue `Distribute #56 <https://bitbucket.org/tarek/distribute/issue/56>`_.

+
+-----
+0.6c9
+-----
+
+ * Fixed a missing files problem when using Windows source distributions on
+   non-Windows platforms, due to distutils not handling manifest file line
+   endings correctly.
+
+ * Updated Pyrex support to work with Pyrex 0.9.6 and higher.
+
+ * Minor changes for Jython compatibility, including skipping tests that can't
+   work on Jython.
+
+ * Fixed not installing eggs in ``install_requires`` if they were also used for
+   ``setup_requires`` or ``tests_require``.
+
+ * Fixed not fetching eggs in ``install_requires`` when running tests.
+
+ * Allow ``ez_setup.use_setuptools()`` to upgrade existing setuptools
+   installations when called from a standalone ``setup.py``.
+
+ * Added a warning if a namespace package is declared, but its parent package
+   is not also declared as a namespace.
+
+ * Support Subversion 1.5
+
+ * Removed use of deprecated ``md5`` module if ``hashlib`` is available
+
+ * Fixed ``bdist_wininst upload`` trying to upload the ``.exe`` twice
+
+ * Fixed ``bdist_egg`` putting a ``native_libs.txt`` in the source package's
+   ``.egg-info``, when it should only be in the built egg's ``EGG-INFO``.
+
+ * Ensure that _full_name is set on all shared libs before extensions are
+   checked for shared lib usage.  (Fixes a bug in the experimental shared
+   library build support.)
+
+ * Fix to allow unpacked eggs containing native libraries to fail more
+   gracefully under Google App Engine (with an ``ImportError`` loading the
+   C-based module, instead of getting a ``NameError``).
+
+-----
+0.6c7
+-----
+
+ * Fixed ``distutils.filelist.findall()`` crashing on broken symlinks, and
+   ``egg_info`` command failing on new, uncommitted SVN directories.
+
+ * Fix import problems with nested namespace packages installed via
+   ``--root`` or ``--single-version-externally-managed``, due to the
+   parent package not having the child package as an attribute.
+
+-----
+0.6c6
+-----
+
+ * Added ``--egg-path`` option to ``develop`` command, allowing you to force
+   ``.egg-link`` files to use relative paths (allowing them to be shared across
+   platforms on a networked drive).
+
+ * Fix not building binary RPMs correctly.
+
+ * Fix "eggsecutables" (such as setuptools' own egg) only being runnable with
+   bash-compatible shells.
+
+ * Fix ``#!`` parsing problems in Windows ``.exe`` script wrappers, when there
+   was whitespace inside a quoted argument or at the end of the ``#!`` line
+   (a regression introduced in 0.6c4).
+
+ * Fix ``test`` command possibly failing if an older version of the project
+   being tested was installed on ``sys.path`` ahead of the test source
+   directory.
+
+ * Fix ``find_packages()`` treating ``ez_setup`` and directories with ``.`` in
+   their names as packages.
+
+-----
+0.6c5
+-----
+
+ * Fix uploaded ``bdist_rpm`` packages being described as ``bdist_egg``
+   packages under Python versions less than 2.5.
+
+ * Fix uploaded ``bdist_wininst`` packages being described as suitable for
+   "any" version by Python 2.5, even if a ``--target-version`` was specified.
+
+-----
+0.6c4
+-----
+
+ * Overhauled Windows script wrapping to support ``bdist_wininst`` better.
+   Scripts installed with ``bdist_wininst`` will always use ``#!python.exe`` or
+   ``#!pythonw.exe`` as the executable name (even when built on non-Windows
+   platforms!), and the wrappers will look for the executable in the script's
+   parent directory (which should find the right version of Python).
+
+ * Fix ``upload`` command not uploading files built by ``bdist_rpm`` or
+   ``bdist_wininst`` under Python 2.3 and 2.4.
+
+ * Add support for "eggsecutable" headers: a ``#!/bin/sh`` script that is
+   prepended to an ``.egg`` file to allow it to be run as a script on Unix-ish
+   platforms.  (This is mainly so that setuptools itself can have a single-file
+   installer on Unix, without doing multiple downloads, dealing with firewalls,
+   etc.)
+
+ * Fix problem with empty revision numbers in Subversion 1.4 ``entries`` files
+
+ * Use cross-platform relative paths in ``easy-install.pth`` when doing
+   ``develop`` and the source directory is a subdirectory of the installation
+   target directory.
+
+ * Fix a problem installing eggs with a system packaging tool if the project
+   contained an implicit namespace package; for example if the ``setup()``
+   listed a namespace package ``foo.bar`` without explicitly listing ``foo``
+   as a namespace package.
+
+-----
+0.6c3
+-----
+
+ * Fixed breakages caused by Subversion 1.4's new "working copy" format
+
+-----
+0.6c2
+-----
+
+ * The ``ez_setup`` module displays the conflicting version of setuptools (and
+   its installation location) when a script requests a version that's not
+   available.
+
+ * Running ``setup.py develop`` on a setuptools-using project will now install
+   setuptools if needed, instead of only downloading the egg.
+
+-----
+0.6c1
+-----
+
+ * Fixed ``AttributeError`` when trying to download a ``setup_requires``
+   dependency when a distribution lacks a ``dependency_links`` setting.
+
+ * Made ``zip-safe`` and ``not-zip-safe`` flag files contain a single byte, so
+   as to play better with packaging tools that complain about zero-length
+   files.
+
+ * Made ``setup.py develop`` respect the ``--no-deps`` option, which it
+   previously was ignoring.
+
+ * Support ``extra_path`` option to ``setup()`` when ``install`` is run in
+   backward-compatibility mode.
+
+ * Source distributions now always include a ``setup.cfg`` file that explicitly
+   sets ``egg_info`` options such that they produce an identical version number
+   to the source distribution's version number.  (Previously, the default
+   version number could be different due to the use of ``--tag-date``, or if
+   the version was overridden on the command line that built the source
+   distribution.)
+
+-----
+0.6b4
+-----
+
+ * Fix ``register`` not obeying name/version set by ``egg_info`` command, if
+   ``egg_info`` wasn't explicitly run first on the same command line.
+
+ * Added ``--no-date`` and ``--no-svn-revision`` options to ``egg_info``
+   command, to allow suppressing tags configured in ``setup.cfg``.
+
+ * Fixed redundant warnings about missing ``README`` file(s); it should now
+   appear only if you are actually a source distribution.
+
+-----
+0.6b3
+-----
+
+ * Fix ``bdist_egg`` not including files in subdirectories of ``.egg-info``.
+
+ * Allow ``.py`` files found by the ``include_package_data`` option to be
+   automatically included.  Remove duplicate data file matches if both
+   ``include_package_data`` and ``package_data`` are used to refer to the same
+   files.
+
+-----
+0.6b1
+-----
+
+ * Strip ``module`` from the end of compiled extension modules when computing
+   the name of a ``.py`` loader/wrapper.  (Python's import machinery ignores
+   this suffix when searching for an extension module.)
+
+------
+0.6a11
+------
+
+ * Added ``test_loader`` keyword to support custom test loaders
+
+ * Added ``setuptools.file_finders`` entry point group to allow implementing
+   revision control plugins.
+
+ * Added ``--identity`` option to ``upload`` command.
+
+ * Added ``dependency_links`` to allow specifying URLs for ``--find-links``.
+
+ * Enhanced test loader to scan packages as well as modules, and call
+   ``additional_tests()`` if present to get non-unittest tests.
+
+ * Support namespace packages in conjunction with system packagers, by omitting
+   the installation of any ``__init__.py`` files for namespace packages, and
+   adding a special ``.pth`` file to create a working package in
+   ``sys.modules``.
+
+ * Made ``--single-version-externally-managed`` automatic when ``--root`` is
+   used, so that most system packagers won't require special support for
+   setuptools.
+
+ * Fixed ``setup_requires``, ``tests_require``, etc. not using ``setup.cfg`` or
+   other configuration files for their option defaults when installing, and
+   also made the install use ``--multi-version`` mode so that the project
+   directory doesn't need to support .pth files.
+
+ * ``MANIFEST.in`` is now forcibly closed when any errors occur while reading
+   it.  Previously, the file could be left open and the actual error would be
+   masked by problems trying to remove the open file on Windows systems.
+
+------
+0.6a10
+------
+
+ * Fixed the ``develop`` command ignoring ``--find-links``.
+
+-----
+0.6a9
+-----
+
+ * The ``sdist`` command no longer uses the traditional ``MANIFEST`` file to
+   create source distributions.  ``MANIFEST.in`` is still read and processed,
+   as are the standard defaults and pruning.  But the manifest is built inside
+   the project's ``.egg-info`` directory as ``SOURCES.txt``, and it is rebuilt
+   every time the ``egg_info`` command is run.
+
+ * Added the ``include_package_data`` keyword to ``setup()``, allowing you to
+   automatically include any package data listed in revision control or
+   ``MANIFEST.in``
+
+ * Added the ``exclude_package_data`` keyword to ``setup()``, allowing you to
+   trim back files included via the ``package_data`` and
+   ``include_package_data`` options.
+
+ * Fixed ``--tag-svn-revision`` not working when run from a source
+   distribution.
+
+ * Added warning for namespace packages with missing ``declare_namespace()``
+
+ * Added ``tests_require`` keyword to ``setup()``, so that e.g. packages
+   requiring ``nose`` to run unit tests can make this dependency optional
+   unless the ``test`` command is run.
+
+ * Made all commands that use ``easy_install`` respect its configuration
+   options, as this was causing some problems with ``setup.py install``.
+
+ * Added an ``unpack_directory()`` driver to ``setuptools.archive_util``, so
+   that you can process a directory tree through a processing filter as if it
+   were a zipfile or tarfile.
+
+ * Added an internal ``install_egg_info`` command to use as part of old-style
+   ``install`` operations, that installs an ``.egg-info`` directory with the
+   package.
+
+ * Added a ``--single-version-externally-managed`` option to the ``install``
+   command so that you can more easily wrap a "flat" egg in a system package.
+
+ * Enhanced ``bdist_rpm`` so that it installs single-version eggs that
+   don't rely on a ``.pth`` file.  The ``--no-egg`` option has been removed,
+   since all RPMs are now built in a more backwards-compatible format.
+
+ * Support full roundtrip translation of eggs to and from ``bdist_wininst``
+   format.  Running ``bdist_wininst`` on a setuptools-based package wraps the
+   egg in an .exe that will safely install it as an egg (i.e., with metadata
+   and entry-point wrapper scripts), and ``easy_install`` can turn the .exe
+   back into an ``.egg`` file or directory and install it as such.
+
+
+-----
+0.6a8
+-----
+
+ * Fixed some problems building extensions when Pyrex was installed, especially
+   with Python 2.4 and/or packages using SWIG.
+
+ * Made ``develop`` command accept all the same options as ``easy_install``,
+   and use the ``easy_install`` command's configuration settings as defaults.
+
+ * Made ``egg_info --tag-svn-revision`` fall back to extracting the revision
+   number from ``PKG-INFO`` in case it is being run on a source distribution of
+   a snapshot taken from a Subversion-based project.
+
+ * Automatically detect ``.dll``, ``.so`` and ``.dylib`` files that are being
+   installed as data, adding them to ``native_libs.txt`` automatically.
+
+ * Fixed some problems with fresh checkouts of projects that don't include
+   ``.egg-info/PKG-INFO`` under revision control and put the project's source
+   code directly in the project directory.  If such a package had any
+   requirements that get processed before the ``egg_info`` command can be run,
+   the setup scripts would fail with a "Missing 'Version:' header and/or
+   PKG-INFO file" error, because the egg runtime interpreted the unbuilt
+   metadata in a directory on ``sys.path`` (i.e. the current directory) as
+   being a corrupted egg.  Setuptools now monkeypatches the distribution
+   metadata cache to pretend that the egg has valid version information, until
+   it has a chance to make it actually be so (via the ``egg_info`` command).
+
+-----
+0.6a5
+-----
+
+ * Fixed missing gui/cli .exe files in distribution.  Fixed bugs in tests.
+
+-----
+0.6a3
+-----
+
+ * Added ``gui_scripts`` entry point group to allow installing GUI scripts
+   on Windows and other platforms.  (The special handling is only for Windows;
+   other platforms are treated the same as for ``console_scripts``.)
+
+-----
+0.6a2
+-----
+
+ * Added ``console_scripts`` entry point group to allow installing scripts
+   without the need to create separate script files.  On Windows, console
+   scripts get an ``.exe`` wrapper so you can just type their name.  On other
+   platforms, the scripts are written without a file extension.
+
+-----
+0.6a1
+-----
+
+ * Added support for building "old-style" RPMs that don't install an egg for
+   the target package, using a ``--no-egg`` option.
+
+ * The ``build_ext`` command now works better when using the ``--inplace``
+   option and multiple Python versions.  It now makes sure that all extensions
+   match the current Python version, even if newer copies were built for a
+   different Python version.
+
+ * The ``upload`` command no longer attaches an extra ``.zip`` when uploading
+   eggs, as PyPI now supports egg uploads without trickery.
+
+ * The ``ez_setup`` script/module now displays a warning before downloading
+   the setuptools egg, and attempts to check the downloaded egg against an
+   internal MD5 checksum table.
+
+ * Fixed the ``--tag-svn-revision`` option of ``egg_info`` not finding the
+   latest revision number; it was using the revision number of the directory
+   containing ``setup.py``, not the highest revision number in the project.
+
+ * Added ``eager_resources`` setup argument
+
+ * The ``sdist`` command now recognizes Subversion "deleted file" entries and
+   does not include them in source distributions.
+
+ * ``setuptools`` now embeds itself more thoroughly into the distutils, so that
+   other distutils extensions (e.g. py2exe, py2app) will subclass setuptools'
+   versions of things, rather than the native distutils ones.
+
+ * Added ``entry_points`` and ``setup_requires`` arguments to ``setup()``;
+   ``setup_requires`` allows you to automatically find and download packages
+   that are needed in order to *build* your project (as opposed to running it).
+
+ * ``setuptools`` now finds its commands, ``setup()`` argument validators, and
+   metadata writers using entry points, so that they can be extended by
+   third-party packages.  See `Creating distutils Extensions
+   <http://pythonhosted.org/setuptools/setuptools.html#creating-distutils-extensions>`_
+   for more details.
+
+ * The vestigial ``depends`` command has been removed.  It was never finished
+   or documented, and never would have worked without EasyInstall - which it
+   pre-dated and was never compatible with.
+
+------
+0.5a12
+------
+
+ * The zip-safety scanner now checks for modules that might be used with
+   ``python -m``, and marks them as unsafe for zipping, since Python 2.4 can't
+   handle ``-m`` on zipped modules.
+
+------
+0.5a11
+------
+
+ * Fix breakage of the "develop" command that was caused by the addition of
+   ``--always-unzip`` to the ``easy_install`` command.
+
+-----
+0.5a9
+-----
+
+ * Include ``svn:externals`` directories in source distributions as well as
+   normal subversion-controlled files and directories.
+
+ * Added ``exclude=patternlist`` option to ``setuptools.find_packages()``
+
+ * Changed --tag-svn-revision to include an "r" in front of the revision number
+   for better readability.
+
+ * Added ability to build eggs without including source files (except for any
+   scripts, of course), using the ``--exclude-source-files`` option to
+   ``bdist_egg``.
+
+ * ``setup.py install`` now automatically detects when an "unmanaged" package
+   or module is going to be on ``sys.path`` ahead of a package being installed,
+   thereby preventing the newer version from being imported.  If this occurs,
+   a warning message is output to ``sys.stderr``, but installation proceeds
+   anyway.  The warning message informs the user what files or directories
+   need deleting, and advises them they can also use EasyInstall (with the
+   ``--delete-conflicting`` option) to do it automatically.
+
+ * The ``egg_info`` command now adds a ``top_level.txt`` file to the metadata
+   directory that lists all top-level modules and packages in the distribution.
+   This is used by the ``easy_install`` command to find possibly-conflicting
+   "unmanaged" packages when installing the distribution.
+
+ * Added ``zip_safe`` and ``namespace_packages`` arguments to ``setup()``.
+   Added package analysis to determine zip-safety if the ``zip_safe`` flag
+   is not given, and advise the author regarding what code might need changing.
+
+ * Fixed the swapped ``-d`` and ``-b`` options of ``bdist_egg``.
+
+-----
+0.5a8
+-----
+
+ * The "egg_info" command now always sets the distribution metadata to "safe"
+   forms of the distribution name and version, so that distribution files will
+   be generated with parseable names (i.e., ones that don't include '-' in the
+   name or version).  Also, this means that if you use the various ``--tag``
+   options of "egg_info", any distributions generated will use the tags in the
+   version, not just egg distributions.
+
+ * Added support for defining command aliases in distutils configuration files,
+   under the "[aliases]" section.  To prevent recursion and to allow aliases to
+   call the command of the same name, a given alias can be expanded only once
+   per command-line invocation.  You can define new aliases with the "alias"
+   command, either for the local, global, or per-user configuration.
+
+ * Added "rotate" command to delete old distribution files, given a set of
+   patterns to match and the number of files to keep.  (Keeps the most
+   recently-modified distribution files matching each pattern.)
+
+ * Added "saveopts" command that saves all command-line options for the current
+   invocation to the local, global, or per-user configuration file.  Useful for
+   setting defaults without having to hand-edit a configuration file.
+
+ * Added a "setopt" command that sets a single option in a specified distutils
+   configuration file.
+
+-----
+0.5a7
+-----
+
+ * Added "upload" support for egg and source distributions, including a bug
+   fix for "upload" and a temporary workaround for lack of .egg support in
+   PyPI.
+
+-----
+0.5a6
+-----
+
+ * Beefed up the "sdist" command so that if you don't have a MANIFEST.in, it
+   will include all files under revision control (CVS or Subversion) in the
+   current directory, and it will regenerate the list every time you create a
+   source distribution, not just when you tell it to.  This should make the
+   default "do what you mean" more often than the distutils' default behavior
+   did, while still retaining the old behavior in the presence of MANIFEST.in.
+
+ * Fixed the "develop" command always updating .pth files, even if you
+   specified ``-n`` or ``--dry-run``.
+
+ * Slightly changed the format of the generated version when you use
+   ``--tag-build`` on the "egg_info" command, so that you can make tagged
+   revisions compare *lower* than the version specified in setup.py (e.g. by
+   using ``--tag-build=dev``).
+
+-----
+0.5a5
+-----
+
+ * Added ``develop`` command to ``setuptools``-based packages.  This command
+   installs an ``.egg-link`` pointing to the package's source directory, and
+   script wrappers that ``execfile()`` the source versions of the package's
+   scripts.  This lets you put your development checkout(s) on sys.path without
+   having to actually install them.  (To uninstall the link, use
+   use ``setup.py develop --uninstall``.)
+
+ * Added ``egg_info`` command to ``setuptools``-based packages.  This command
+   just creates or updates the "projectname.egg-info" directory, without
+   building an egg.  (It's used by the ``bdist_egg``, ``test``, and ``develop``
+   commands.)
+
+ * Enhanced the ``test`` command so that it doesn't install the package, but
+   instead builds any C extensions in-place, updates the ``.egg-info``
+   metadata, adds the source directory to ``sys.path``, and runs the tests
+   directly on the source.  This avoids an "unmanaged" installation of the
+   package to ``site-packages`` or elsewhere.
+
+ * Made ``easy_install`` a standard ``setuptools`` command, moving it from
+   the ``easy_install`` module to ``setuptools.command.easy_install``.  Note
+   that if you were importing or extending it, you must now change your imports
+   accordingly.  ``easy_install.py`` is still installed as a script, but not as
+   a module.
+
+-----
+0.5a4
+-----
+
+ * Setup scripts using setuptools can now list their dependencies directly in
+   the setup.py file, without having to manually create a ``depends.txt`` file.
+   The ``install_requires`` and ``extras_require`` arguments to ``setup()``
+   are used to create a dependencies file automatically.  If you are manually
+   creating ``depends.txt`` right now, please switch to using these setup
+   arguments as soon as practical, because ``depends.txt`` support will be
+   removed in the 0.6 release cycle.  For documentation on the new arguments,
+   see the ``setuptools.dist.Distribution`` class.
+
+ * Setup scripts using setuptools now always install using ``easy_install``
+   internally, for ease of uninstallation and upgrading.
+
+-----
+0.5a1
+-----
+
+ * Added support for "self-installation" bootstrapping.  Packages can now
+   include ``ez_setup.py`` in their source distribution, and add the following
+   to their ``setup.py``, in order to automatically bootstrap installation of
+   setuptools as part of their setup process::
+
+    from ez_setup import use_setuptools
+    use_setuptools()
+
+    from setuptools import setup
+    # etc...
+
+-----
+0.4a2
+-----
+
+ * Added ``ez_setup.py`` installer/bootstrap script to make initial setuptools
+   installation easier, and to allow distributions using setuptools to avoid
+   having to include setuptools in their source distribution.
+
+ * All downloads are now managed by the ``PackageIndex`` class (which is now
+   subclassable and replaceable), so that embedders can more easily override
+   download logic, give download progress reports, etc.  The class has also
+   been moved to the new ``setuptools.package_index`` module.
+
+ * The ``Installer`` class no longer handles downloading, manages a temporary
+   directory, or tracks the ``zip_ok`` option.  Downloading is now handled
+   by ``PackageIndex``, and ``Installer`` has become an ``easy_install``
+   command class based on ``setuptools.Command``.
+
+ * There is a new ``setuptools.sandbox.run_setup()`` API to invoke a setup
+   script in a directory sandbox, and a new ``setuptools.archive_util`` module
+   with an ``unpack_archive()`` API.  These were split out of EasyInstall to
+   allow reuse by other tools and applications.
+
+ * ``setuptools.Command`` now supports reinitializing commands using keyword
+   arguments to set/reset options.  Also, ``Command`` subclasses can now set
+   their ``command_consumes_arguments`` attribute to ``True`` in order to
+   receive an ``args`` option containing the rest of the command line.
+
+-----
+0.3a2
+-----
+
+ * Added new options to ``bdist_egg`` to allow tagging the egg's version number
+   with a subversion revision number, the current date, or an explicit tag
+   value.  Run ``setup.py bdist_egg --help`` to get more information.
+
+ * Misc. bug fixes
+
+-----
+0.3a1
+-----
+
+ * Initial release.

+    """Distribution with support for features, tests, and package data
+
+    This is an enhanced version of 'distutils.dist.Distribution' that
+    effectively adds the following new optional keyword arguments to 'setup()':
+
+     'install_requires' -- a string or sequence of strings specifying project
+        versions that the distribution requires when installed, in the format
+        used by 'pkg_resources.require()'.  They will be installed
+        automatically when the package is installed.  If you wish to use
+        packages that are not available in PyPI, or want to give your users an
+        alternate download location, you can add a 'find_links' option to the
+        '[easy_install]' section of your project's 'setup.cfg' file, and then
+        setuptools will scan the listed web pages for links that satisfy the
+        requirements.
+
+     'extras_require' -- a dictionary mapping names of optional "extras" to the
+        additional requirement(s) that using those extras incurs. For example,
+        this::
+
+            extras_require = dict(reST = ["docutils>=0.3", "reSTedit"])
+
+        indicates that the distribution can optionally provide an extra
+        capability called "reST", but it can only be used if docutils and
+        reSTedit are installed.  If the user installs your package using
+        EasyInstall and requests one of your extras, the corresponding
+        additional requirements will be installed if needed.
+
+     'features' **deprecated** -- a dictionary mapping option names to
+        'setuptools.Feature'
+        objects.  Features are a portion of the distribution that can be
+        included or excluded based on user options, inter-feature dependencies,
+        and availability on the current system.  Excluded features are omitted
+        from all setup commands, including source and binary distributions, so
+        you can create multiple distributions from the same source tree.
+        Feature names should be valid Python identifiers, except that they may
+        contain the '-' (minus) sign.  Features can be included or excluded
+        via the command line options '--with-X' and '--without-X', where 'X' is
+        the name of the feature.  Whether a feature is included by default, and
+        whether you are allowed to control this from the command line, is
+        determined by the Feature object.  See the 'Feature' class for more
+        information.
+
+     'test_suite' -- the name of a test suite to run for the 'test' command.
+        If the user runs 'python setup.py test', the package will be installed,
+        and the named test suite will be run.  The format is the same as
+        would be used on a 'unittest.py' command line.  That is, it is the
+        dotted name of an object to import and call to generate a test suite.
+
+     'package_data' -- a dictionary mapping package names to lists of filenames
+        or globs to use to find data files contained in the named packages.
+        If the dictionary has filenames or globs listed under '""' (the empty
+        string), those names will be searched for in every package, in addition
+        to any names for the specific package.  Data files found using these
+        names/globs will be installed along with the package, in the same
+        location as the package.  Note that globs are allowed to reference
+        the contents of non-package subdirectories, as long as you use '/' as
+        a path separator.  (Globs are automatically converted to
+        platform-specific paths at runtime.)
+
+    In addition to these new keywords, this class also has several new methods
+    for manipulating the distribution's contents.  For example, the 'include()'
+    and 'exclude()' methods can be thought of as in-place add and subtract
+    commands that add or remove packages, modules, extensions, and so on from
+    the distribution.  They are used by the feature subsystem to configure the
+    distribution for the included and excluded features.

+    **deprecated** -- The `Feature` facility was never completely implemented

+    <https://bitbucket.org/pypa/setuptools/issue/58>`_ and will be removed in
+    a future version.
+
+    A subset of the distribution that can be excluded if unneeded/wanted
+
+    Features are created using these keyword arguments:
+
+      'description' -- a short, human readable description of the feature, to
+         be used in error messages, and option help messages.
+
+      'standard' -- if true, the feature is included by default if it is
+         available on the current system.  Otherwise, the feature is only
+         included if requested via a command line '--with-X' option, or if
+         another included feature requires it.  The default setting is 'False'.
+
+      'available' -- if true, the feature is available for installation on the
+         current system.  The default setting is 'True'.
+
+      'optional' -- if true, the feature's inclusion can be controlled from the
+         command line, using the '--with-X' or '--without-X' options.  If
+         false, the feature's inclusion status is determined automatically,
+         based on 'availabile', 'standard', and whether any other feature
+         requires it.  The default setting is 'True'.
+
+      'require_features' -- a string or sequence of strings naming features
+         that should also be included if this feature is included.  Defaults to
+         empty list.  May also contain 'Require' objects that should be
+         added/removed from the distribution.
+
+      'remove' -- a string or list of strings naming packages to be removed
+         from the distribution if this feature is *not* included.  If the
+         feature *is* included, this argument is ignored.  This argument exists
+         to support removing features that "crosscut" a distribution, such as
+         defining a 'tests' feature that removes all the 'tests' subpackages
+         provided by other features.  The default for this argument is an empty
+         list.  (Note: the named package(s) or modules must exist in the base
+         distribution when the 'setup()' function is initially called.)
+
+      other keywords -- any other keyword arguments are saved, and passed to
+         the distribution's 'include()' and 'exclude()' methods when the
+         feature is included or excluded, respectively.  So, for example, you
+         could pass 'packages=["a","b"]' to cause packages 'a' and 'b' to be
+         added or removed from the distribution as appropriate.
+
+    A feature must include at least one 'requires', 'remove', or other
+    keyword argument.  Otherwise, it can't affect the distribution in any way.
+    Note also that you can subclass 'Feature' to create your own specialized
+    feature types that modify the distribution in other ways when included or
+    excluded.  See the docstrings for the various methods here for more detail.
+    Aside from the methods, the only feature attributes that distributions look
+    at are 'description' and 'optional'.

+r"""Module doctest -- a framework for running examples in docstrings.
+
+In simplest use, end each module M to be tested with:
+
+def _test():
+    import doctest
+    doctest.testmod()
+
+if __name__ == "__main__":
+    _test()
+
+Then running the module as a script will cause the examples in the
+docstrings to get executed and verified:
+
+python M.py
+
+This won't display anything unless an example fails, in which case the
+failing example(s) and the cause(s) of the failure(s) are printed to stdout
+(why not stderr? because stderr is a lame hack <0.2 wink>), and the final
+line of output is "Test failed.".
+
+Run it with the -v switch instead:
+
+python M.py -v
+
+and a detailed report of all examples tried is printed to stdout, along
+with assorted summaries at the end.
+
+You can force verbose mode by passing "verbose=True" to testmod, or prohibit
+it by passing "verbose=False".  In either of those cases, sys.argv is not
+examined by testmod.
+
+There are a variety of other ways to run doctests, including integration
+with the unittest framework, and support for running non-Python text
+files containing doctests.  There are also many ways to override parts
+of doctest's default behaviors.  See the Library Reference Manual for
+details.

+    A class used to run DocTest test cases, and accumulate statistics.
+    The `run` method is used to process a single DocTest case.  It
+    returns a tuple `(f, t)`, where `t` is the number of test cases
+    tried, and `f` is the number of test cases that failed.
+
+        >>> tests = DocTestFinder().find(_TestClass)

+        (0, 1)
+        (0, 2)
+        (0, 2)
+
+    The `summarize` method prints a summary of all the test cases that
+    have been run by the runner, and returns an aggregated `(f, t)`
+    tuple:
+
+        >>> runner.summarize(verbose=1)
+        4 items passed all tests:
+           2 tests in _TestClass
+           2 tests in _TestClass.__init__
+           2 tests in _TestClass.get

+        7 passed and 0 failed.
+        Test passed.
+        (0, 7)
+
+    The aggregated number of tried examples and failed examples is
+    also available via the `tries` and `failures` attributes:

+        >>> runner.tries
+        7
+        >>> runner.failures
+        0
+
+    The comparison between expected outputs and actual outputs is done
+    by an `OutputChecker`.  This comparison may be customized with a
+    number of option flags; see the documentation for `testmod` for
+    more information.  If the option flags are insufficient, then the
+    comparison may also be customized by passing a subclass of
+    `OutputChecker` to the constructor.
+
+    The test runner's display output can be controlled in two ways.
+    First, an output function (`out) can be passed to
+    `TestRunner.run`; this function will be called with strings that
+    should be displayed.  It defaults to `sys.stdout.write`.  If
+    capturing the output is not sufficient, then the display output
+    can be also customized by subclassing DocTestRunner, and
+    overriding the methods `report_start`, `report_success`,
+    `report_unexpected_exception`, and `report_failure`.

+
+Drizzle is a variant of MySQL. Unlike MySQL, Drizzle's default storage engine
+is InnoDB (transactions, foreign-keys) rather than MyISAM. For more
+`Notable Differences <http://docs.drizzle.org/mysql_differences.html>`_, visit
+the `Drizzle Documentation <http://docs.drizzle.org/index.html>`_.
+
+The SQLAlchemy Drizzle dialect leans heavily on the MySQL dialect, so much of

+.. dialect:: firebird
+    :name: Firebird
+
+Firebird Dialects
+-----------------
+
+Firebird offers two distinct dialects_ (not to be confused with a
+SQLAlchemy ``Dialect``):
+
+dialect 1
+  This is the old syntax and behaviour, inherited from Interbase pre-6.0.
+
+dialect 3
+  This is the newer and supported syntax, introduced in Interbase 6.0.
+
+The SQLAlchemy Firebird dialect detects these versions and
+adjusts its representation of SQL accordingly.  However,
+support for dialect 1 is not well tested and probably has
+incompatibilities.
+
+Locking Behavior
+----------------
+
+Firebird locks tables aggressively.  For this reason, a DROP TABLE may
+hang until other transactions are released.  SQLAlchemy does its best
+to release transactions as quickly as possible.  The most common cause
+of hanging transactions is a non-fully consumed result set, i.e.::
+
+    result = engine.execute("select * from table")
+    row = result.fetchone()
+    return
+
+Where above, the ``ResultProxy`` has not been fully consumed.  The
+connection will be returned to the pool and the transactional state
+rolled back once the Python garbage collector reclaims the objects
+which hold onto the connection, which often occurs asynchronously.
+The above use case can be alleviated by calling ``first()`` on the
+``ResultProxy`` which will fetch the first row and immediately close
+all remaining cursor/connection resources.
+
+RETURNING support
+-----------------
+
+Firebird 2.0 supports returning a result set from inserts, and 2.1
+extends that to deletes and updates. This is generically exposed by
+the SQLAlchemy ``returning()`` method, such as::
+
+    # INSERT..RETURNING
+    result = table.insert().returning(table.c.col1, table.c.col2).\\
+                   values(name='foo')
+    print result.fetchall()
+
+    # UPDATE..RETURNING
+    raises = empl.update().returning(empl.c.id, empl.c.salary).\\
+                  where(empl.c.sales>100).\\
+                  values(dict(salary=empl.c.salary * 1.1))
+    print raises.fetchall()

+.. dialect:: firebird+fdb
+    :name: fdb
+    :dbapi: pyodbc
+    :connectstring: firebird+fdb://user:password@host:port/path/to/db\
+[?key=value&key=value...]
+    :url: http://pypi.python.org/pypi/fdb/
+
+    fdb is a kinterbasdb compatible DBAPI for Firebird.
+
+    .. versionadded:: 0.8 - Support for the fdb Firebird driver.
+
+    .. versionchanged:: 0.9 - The fdb dialect is now the default dialect
+       under the ``firebird://`` URL space, as ``fdb`` is now the official
+       Python driver for Firebird.
+
+Arguments
+----------
+
+The ``fdb`` dialect is based on the
+:mod:`sqlalchemy.dialects.firebird.kinterbasdb` dialect, however does not
+accept every argument that Kinterbasdb does.
+
+* ``enable_rowcount`` - True by default, setting this to False disables
+  the usage of "cursor.rowcount" with the
+  Kinterbasdb dialect, which SQLAlchemy ordinarily calls upon automatically
+  after any UPDATE or DELETE statement.   When disabled, SQLAlchemy's
+  ResultProxy will return -1 for result.rowcount.   The rationale here is
+  that Kinterbasdb requires a second round trip to the database when
+  .rowcount is called -  since SQLA's resultproxy automatically closes
+  the cursor after a non-result-returning statement, rowcount must be
+  called, if at all, before the result object is returned.   Additionally,
+  cursor.rowcount may not return correct results with older versions
+  of Firebird, and setting this flag to False will also cause the
+  SQLAlchemy ORM to ignore its usage. The behavior can also be controlled on a
+  per-execution basis using the ``enable_rowcount`` option with
+  :meth:`.Connection.execution_options`::
+
+      conn = engine.connect().execution_options(enable_rowcount=True)
+      r = conn.execute(stmt)
+      print r.rowcount
+
+* ``retaining`` - False by default.   Setting this to True will pass the
+  ``retaining=True`` keyword argument to the ``.commit()`` and ``.rollback()``
+  methods of the DBAPI connection, which can improve performance in some
+  situations, but apparently with significant caveats.
+  Please read the fdb and/or kinterbasdb DBAPI documentation in order to
+  understand the implications of this flag.
+
+  .. versionadded:: 0.8.2 - ``retaining`` keyword argument specifying
+     transaction retaining behavior - in 0.8 it defaults to ``True``
+     for backwards compatibility.
+
+  .. versionchanged:: 0.9.0 - the ``retaining`` flag defaults to ``False``.
+     In 0.8 it defaulted to ``True``.
+
+  .. seealso::
+
+    http://pythonhosted.org/fdb/usage-guide.html#retaining-transactions
+    - information on the "retaining" flag.

+
+
+Auto Increment Behavior
+-----------------------
+
+SQL Server provides so-called "auto incrementing" behavior using the
+``IDENTITY`` construct, which can be placed on an integer primary key.
+SQLAlchemy considers ``IDENTITY`` within its default "autoincrement" behavior,
+described at :paramref:`.Column.autoincrement`; this means
+that by default, the first integer primary key column in a :class:`.Table`
+will be considered to be the identity column and will generate DDL as such::
+
+    from sqlalchemy import Table, MetaData, Column, Integer
+
+    m = MetaData()
+    t = Table('t', m,
+            Column('id', Integer, primary_key=True),
+            Column('x', Integer))
+    m.create_all(engine)
+
+The above example will generate DDL as:
+
+.. sourcecode:: sql
+
+    CREATE TABLE t (
+        id INTEGER NOT NULL IDENTITY(1,1),
+        x INTEGER NULL,
+        PRIMARY KEY (id)
+    )
+
+For the case where this default generation of ``IDENTITY`` is not desired,
+specify ``autoincrement=False`` on all integer primary key columns::
+
+    m = MetaData()
+    t = Table('t', m,
+            Column('id', Integer, primary_key=True, autoincrement=False),
+            Column('x', Integer))
+    m.create_all(engine)
+
+.. note::
+
+    An INSERT statement which refers to an explicit value for such
+    a column is prohibited by SQL Server, however SQLAlchemy will detect this
+    and modify the ``IDENTITY_INSERT`` flag accordingly at statement execution
+    time.  As this is not a high performing process, care should be taken to
+    set the ``autoincrement`` flag appropriately for columns that will not
+    actually require IDENTITY behavior.
+
+Controlling "Start" and "Increment"
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Specific control over the parameters of the ``IDENTITY`` value is supported
+using the :class:`.schema.Sequence` object.  While this object normally
+represents an explicit "sequence" for supporting backends, on SQL Server it is
+re-purposed to specify behavior regarding the identity column, including
+support of the "start" and "increment" values::
+
+    from sqlalchemy import Table, Integer, Sequence, Column
+
+    Table('test', metadata,
+           Column('id', Integer,
+                  Sequence('blah', start=100, increment=10),
+                  primary_key=True),
+           Column('name', String(20))
+         ).create(some_engine)
+
+would yield:
+
+.. sourcecode:: sql
+
+   CREATE TABLE test (
+     id INTEGER NOT NULL IDENTITY(100,10) PRIMARY KEY,
+     name VARCHAR(20) NULL,
+     )
+
+Note that the ``start`` and ``increment`` values for sequences are
+optional and will default to 1,1.
+
+INSERT behavior
+^^^^^^^^^^^^^^^^
+
+Handling of the ``IDENTITY`` column at INSERT time involves two key
+techniques. The most common is being able to fetch the "last inserted value"
+for a given ``IDENTITY`` column, a process which SQLAlchemy performs
+implicitly in many cases, most importantly within the ORM.
+
+The process for fetching this value has several variants:
+
+* In the vast majority of cases, RETURNING is used in conjunction with INSERT
+  statements on SQL Server in order to get newly generated primary key values:
+
+  .. sourcecode:: sql
+
+    INSERT INTO t (x) OUTPUT inserted.id VALUES (?)
+
+* When RETURNING is not available or has been disabled via
+  ``implicit_returning=False``, either the ``scope_identity()`` function or
+  the ``@@identity`` variable is used; behavior varies by backend:
+
+  * when using PyODBC, the phrase ``; select scope_identity()`` will be
+    appended to the end of the INSERT statement; a second result set will be
+    fetched in order to receive the value.  Given a table as::
+
+        t = Table('t', m, Column('id', Integer, primary_key=True),
+                Column('x', Integer),
+                implicit_returning=False)
+
+    an INSERT will look like:
+
+    .. sourcecode:: sql
+
+        INSERT INTO t (x) VALUES (?); select scope_identity()
+
+  * Other dialects such as pymssql will call upon
+    ``SELECT scope_identity() AS lastrowid`` subsequent to an INSERT
+    statement. If the flag ``use_scope_identity=False`` is passed to
+    :func:`.create_engine`, the statement ``SELECT @@identity AS lastrowid``
+    is used instead.
+
+A table that contains an ``IDENTITY`` column will prohibit an INSERT statement
+that refers to the identity column explicitly.  The SQLAlchemy dialect will
+detect when an INSERT construct, created using a core :func:`.insert`
+construct (not a plain string SQL), refers to the identity column, and
+in this case will emit ``SET IDENTITY_INSERT ON`` prior to the insert
+statement proceeding, and ``SET IDENTITY_INSERT OFF`` subsequent to the
+execution.  Given this example::
+
+    m = MetaData()
+    t = Table('t', m, Column('id', Integer, primary_key=True),
+                    Column('x', Integer))
+    m.create_all(engine)
+
+    engine.execute(t.insert(), {'id': 1, 'x':1}, {'id':2, 'x':2})
+
+The above column will be created with IDENTITY, however the INSERT statement
+we emit is specifying explicit values.  In the echo output we can see
+how SQLAlchemy handles this:
+
+.. sourcecode:: sql
+
+    CREATE TABLE t (
+        id INTEGER NOT NULL IDENTITY(1,1),
+        x INTEGER NULL,
+        PRIMARY KEY (id)
+    )
+
+    COMMIT
+    SET IDENTITY_INSERT t ON
+    INSERT INTO t (id, x) VALUES (?, ?)
+    ((1, 1), (2, 2))
+    SET IDENTITY_INSERT t OFF
+    COMMIT
+
+
+
+This
+is an auxilliary use case suitable for testing and bulk insert scenarios.
+
+
+Collation Support
+-----------------
+
+Character collations are supported by the base string types,
+specified by the string argument "collation"::
+
+    from sqlalchemy import VARCHAR
+    Column('login', VARCHAR(32, collation='Latin1_General_CI_AS'))
+
+When such a column is associated with a :class:`.Table`, the
+CREATE TABLE statement for this column will yield::
+
+    login VARCHAR(32) COLLATE Latin1_General_CI_AS NULL
+
+.. versionadded:: 0.8 Character collations are now part of the base string
+   types.
+
+LIMIT/OFFSET Support
+--------------------
+
+MSSQL has no support for the LIMIT or OFFSET keysowrds. LIMIT is
+supported directly through the ``TOP`` Transact SQL keyword::
+
+    select.limit
+
+will yield::
+
+    SELECT TOP n
+
+If using SQL Server 2005 or above, LIMIT with OFFSET
+support is available through the ``ROW_NUMBER OVER`` construct.
+For versions below 2005, LIMIT with OFFSET usage will fail.
+
+Nullability
+-----------
+MSSQL has support for three levels of column nullability. The default
+nullability allows nulls and is explicit in the CREATE TABLE
+construct::
+
+    name VARCHAR(20) NULL
+
+If ``nullable=None`` is specified then no specification is made. In
+other words the database's configured default is used. This will
+render::
+
+    name VARCHAR(20)
+
+If ``nullable`` is ``True`` or ``False`` then the column will be
+``NULL` or ``NOT NULL`` respectively.
+
+Date / Time Handling
+--------------------
+DATE and TIME are supported.   Bind parameters are converted
+to datetime.datetime() objects as required by most MSSQL drivers,
+and results are processed from strings if needed.
+The DATE and TIME types are not available for MSSQL 2005 and
+previous - if a server version below 2008 is detected, DDL
+for these types will be issued as DATETIME.
+
+.. _mssql_indexes:
+
+Clustered Index Support
+-----------------------
+
+The MSSQL dialect supports clustered indexes (and primary keys) via the
+``mssql_clustered`` option.  This option is available to :class:`.Index`,
+:class:`.UniqueConstraint`. and :class:`.PrimaryKeyConstraint`.
+
+To generate a clustered index::
+
+    Index("my_index", table.c.x, mssql_clustered=True)
+
+which renders the index as ``CREATE CLUSTERED INDEX my_index ON table (x)``.
+
+.. versionadded:: 0.8
+
+To generate a clustered primary key use::
+
+    Table('my_table', metadata,
+          Column('x', ...),
+          Column('y', ...),
+          PrimaryKeyConstraint("x", "y", mssql_clustered=True))
+
+which will render the table, for example, as::
+
+  CREATE TABLE my_table (x INTEGER NOT NULL, y INTEGER NOT NULL,
+                         PRIMARY KEY CLUSTERED (x, y))
+
+Similarly, we can generate a clustered unique constraint using::
+
+    Table('my_table', metadata,
+          Column('x', ...),
+          Column('y', ...),
+          PrimaryKeyConstraint("x"),
+          UniqueConstraint("y", mssql_clustered=True),
+          )
+
+  .. versionadded:: 0.9.2
+
+MSSQL-Specific Index Options
+-----------------------------
+
+In addition to clustering, the MSSQL dialect supports other special options
+for :class:`.Index`.
+
+INCLUDE
+^^^^^^^
+
+The ``mssql_include`` option renders INCLUDE(colname) for the given string
+names::
+
+    Index("my_index", table.c.x, mssql_include=['y'])
+
+would render the index as ``CREATE INDEX my_index ON table (x) INCLUDE (y)``
+
+.. versionadded:: 0.8
+
+Index ordering
+^^^^^^^^^^^^^^
+
+Index ordering is available via functional expressions, such as::
+
+    Index("my_index", table.c.x.desc())
+
+would render the index as ``CREATE INDEX my_index ON table (x DESC)``
+
+.. versionadded:: 0.8
+
+.. seealso::
+
+    :ref:`schema_indexes_functional`
+
+Compatibility Levels
+--------------------
+MSSQL supports the notion of setting compatibility levels at the
+database level. This allows, for instance, to run a database that
+is compatible with SQL2000 while running on a SQL2005 database
+server. ``server_version_info`` will always return the database
+server version information (in this case SQL2005) and not the
+compatibility level information. Because of this, if running under
+a backwards compatibility mode SQAlchemy may attempt to use T-SQL
+statements that are unable to be parsed by the database server.
+
+Triggers
+--------
+
+SQLAlchemy by default uses OUTPUT INSERTED to get at newly
+generated primary key values via IDENTITY columns or other
+server side defaults.   MS-SQL does not
+allow the usage of OUTPUT INSERTED on tables that have triggers.
+To disable the usage of OUTPUT INSERTED on a per-table basis,
+specify ``implicit_returning=False`` for each :class:`.Table`
+which has triggers::
+
+    Table('mytable', metadata,
+        Column('id', Integer, primary_key=True),
+        # ...,
+        implicit_returning=False
+    )
+
+Declarative form::
+
+    class MyClass(Base):
+        # ...
+        __table_args__ = {'implicit_returning':False}
+
+
+This option can also be specified engine-wide using the
+``implicit_returning=False`` argument on :func:`.create_engine`.
+
+Enabling Snapshot Isolation
+---------------------------
+
+Not necessarily specific to SQLAlchemy, SQL Server has a default transaction
+isolation mode that locks entire tables, and causes even mildly concurrent
+applications to have long held locks and frequent deadlocks.
+Enabling snapshot isolation for the database as a whole is recommended
+for modern levels of concurrency support.  This is accomplished via the
+following ALTER DATABASE commands executed at the SQL prompt::
+
+    ALTER DATABASE MyDatabase SET ALLOW_SNAPSHOT_ISOLATION ON
+
+    ALTER DATABASE MyDatabase SET READ_COMMITTED_SNAPSHOT ON
+
+Background on SQL Server snapshot isolation is available at
+http://msdn.microsoft.com/en-us/library/ms175095.aspx.
+

+
+Execution Modes
+---------------
+
+mxODBC features two styles of statement execution, using the
+``cursor.execute()`` and ``cursor.executedirect()`` methods (the second being
+an extension to the DBAPI specification). The former makes use of a particular
+API call specific to the SQL Server Native Client ODBC driver known
+SQLDescribeParam, while the latter does not.
+
+mxODBC apparently only makes repeated use of a single prepared statement
+when SQLDescribeParam is used. The advantage to prepared statement reuse is
+one of performance. The disadvantage is that SQLDescribeParam has a limited
+set of scenarios in which bind parameters are understood, including that they
+cannot be placed within the argument lists of function calls, anywhere outside
+the FROM, or even within subqueries within the FROM clause - making the usage
+of bind parameters within SELECT statements impossible for all but the most
+simplistic statements.
+
+For this reason, the mxODBC dialect uses the "native" mode by default only for
+INSERT, UPDATE, and DELETE statements, and uses the escaped string mode for
+all other statements.
+
+This behavior can be controlled via
+:meth:`~sqlalchemy.sql.expression.Executable.execution_options` using the
+``native_odbc_execute`` flag with a value of ``True`` or ``False``, where a
+value of ``True`` will unconditionally use native bind parameters and a value
+of ``False`` will unconditionally use string-escaped parameters.

+Additional Connection Examples
+-------------------------------
+
+Examples of pyodbc connection string URLs:
+
+* ``mssql+pyodbc://mydsn`` - connects using the specified DSN named ``mydsn``.
+  The connection string that is created will appear like::
+
+    dsn=mydsn;Trusted_Connection=Yes
+
+* ``mssql+pyodbc://user:pass@mydsn`` - connects using the DSN named
+  ``mydsn`` passing in the ``UID`` and ``PWD`` information. The
+  connection string that is created will appear like::
+
+    dsn=mydsn;UID=user;PWD=pass
+
+* ``mssql+pyodbc://user:pass@mydsn/?LANGUAGE=us_english`` - connects
+  using the DSN named ``mydsn`` passing in the ``UID`` and ``PWD``
+  information, plus the additional connection configuration option
+  ``LANGUAGE``. The connection string that is created will appear
+  like::
+
+    dsn=mydsn;UID=user;PWD=pass;LANGUAGE=us_english
+
+* ``mssql+pyodbc://user:pass@host/db`` - connects using a connection
+  that would appear like::
+
+    DRIVER={SQL Server};Server=host;Database=db;UID=user;PWD=pass
+
+* ``mssql+pyodbc://user:pass@host:123/db`` - connects using a connection
+  string which includes the port
+  information using the comma syntax. This will create the following
+  connection string::
+
+    DRIVER={SQL Server};Server=host,123;Database=db;UID=user;PWD=pass
+
+* ``mssql+pyodbc://user:pass@host/db?port=123`` - connects using a connection
+  string that includes the port
+  information as a separate ``port`` keyword. This will create the
+  following connection string::
+
+    DRIVER={SQL Server};Server=host;Database=db;UID=user;PWD=pass;port=123
+
+* ``mssql+pyodbc://user:pass@host/db?driver=MyDriver`` - connects using a
+  connection string that includes a custom ODBC driver name.  This will create
+  the following connection string::
+
+    DRIVER={MyDriver};Server=host;Database=db;UID=user;PWD=pass
+
+If you require a connection string that is outside the options
+presented above, use the ``odbc_connect`` keyword to pass in a
+urlencoded connection string. What gets passed in will be urldecoded
+and passed directly.
+
+For example::
+
+    mssql+pyodbc:///?odbc_connect=dsn%3Dmydsn%3BDatabase%3Ddb
+
+would create the following connection string::
+
+    dsn=mydsn;Database=db
+
+Encoding your connection string can be easily accomplished through
+the python shell. For example::
+
+    >>> import urllib
+    >>> urllib.quote_plus('dsn=mydsn;Database=db')
+    'dsn%3Dmydsn%3BDatabase%3Ddb'
+
+Unicode Binds
+-------------
+
+The current state of PyODBC on a unix backend with FreeTDS and/or
+EasySoft is poor regarding unicode; different OS platforms and versions of
+UnixODBC versus IODBC versus FreeTDS/EasySoft versus PyODBC itself
+dramatically alter how strings are received.  The PyODBC dialect attempts to
+use all the information it knows to determine whether or not a Python unicode
+literal can be passed directly to the PyODBC driver or not; while SQLAlchemy
+can encode these to bytestrings first, some users have reported that PyODBC
+mis-handles bytestrings for certain encodings and requires a Python unicode
+object, while the author has observed widespread cases where a Python unicode
+is completely misinterpreted by PyODBC, particularly when dealing with
+the information schema tables used in table reflection, and the value
+must first be encoded to a bytestring.
+
+It is for this reason that whether or not unicode literals for bound
+parameters be sent to PyODBC can be controlled using the
+``supports_unicode_binds`` parameter to ``create_engine()``.  When
+left at its default of ``None``, the PyODBC dialect will use its
+best guess as to whether or not the driver deals with unicode literals
+well.  When ``False``, unicode literals will be encoded first, and when
+``True`` unicode literals will be passed straight through.  This is an interim
+flag that hopefully should not be needed when the unicode situation stabilizes
+for unix + PyODBC.

+.. dialect:: mysql
+    :name: MySQL
+
+Supported Versions and Features
+-------------------------------
+
+SQLAlchemy supports MySQL starting with version 4.1 through modern releases.
+However, no heroic measures are taken to work around major missing
+SQL features - if your server version does not support sub-selects, for
+example, they won't work in SQLAlchemy either.
+
+See the official MySQL documentation for detailed information about features
+supported in any given server release.
+
+.. _mysql_connection_timeouts:
+
+Connection Timeouts
+-------------------
+
+MySQL features an automatic connection close behavior, for connections that
+have been idle for eight hours or more.   To circumvent having this issue, use
+the ``pool_recycle`` option which controls the maximum age of any connection::
+
+    engine = create_engine('mysql+mysqldb://...', pool_recycle=3600)
+
+.. _mysql_storage_engines:
+
+CREATE TABLE arguments including Storage Engines
+------------------------------------------------
+
+MySQL's CREATE TABLE syntax includes a wide array of special options,
+including ``ENGINE``, ``CHARSET``, ``MAX_ROWS``, ``ROW_FORMAT``,
+``INSERT_METHOD``, and many more.
+To accommodate the rendering of these arguments, specify the form
+``mysql_argument_name="value"``.  For example, to specify a table with
+``ENGINE`` of ``InnoDB``, ``CHARSET`` of ``utf8``, and ``KEY_BLOCK_SIZE``
+of ``1024``::
+
+  Table('mytable', metadata,
+        Column('data', String(32)),
+        mysql_engine='InnoDB',
+        mysql_charset='utf8',
+        mysql_key_block_size="1024"
+       )
+
+The MySQL dialect will normally transfer any keyword specified as
+``mysql_keyword_name`` to be rendered as ``KEYWORD_NAME`` in the
+``CREATE TABLE`` statement.  A handful of these names will render with a space
+instead of an underscore; to support this, the MySQL dialect has awareness of
+these particular names, which include ``DATA DIRECTORY``
+(e.g. ``mysql_data_directory``), ``CHARACTER SET`` (e.g.
+``mysql_character_set``) and ``INDEX DIRECTORY`` (e.g.
+``mysql_index_directory``).
+
+The most common argument is ``mysql_engine``, which refers to the storage
+engine for the table.  Historically, MySQL server installations would default
+to ``MyISAM`` for this value, although newer versions may be defaulting
+to ``InnoDB``.  The ``InnoDB`` engine is typically preferred for its support
+of transactions and foreign keys.
+
+A :class:`.Table` that is created in a MySQL database with a storage engine
+of ``MyISAM`` will be essentially non-transactional, meaning any
+INSERT/UPDATE/DELETE statement referring to this table will be invoked as
+autocommit.   It also will have no support for foreign key constraints; while
+the ``CREATE TABLE`` statement accepts foreign key options, when using the
+``MyISAM`` storage engine these arguments are discarded.  Reflecting such a
+table will also produce no foreign key constraint information.
+
+For fully atomic transactions as well as support for foreign key
+constraints, all participating ``CREATE TABLE`` statements must specify a
+transactional engine, which in the vast majority of cases is ``InnoDB``.
+
+.. seealso::
+
+    `The InnoDB Storage Engine
+    <http://dev.mysql.com/doc/refman/5.0/en/innodb-storage-engine.html>`_ -
+    on the MySQL website.
+
+Case Sensitivity and Table Reflection
+-------------------------------------
+
+MySQL has inconsistent support for case-sensitive identifier
+names, basing support on specific details of the underlying
+operating system. However, it has been observed that no matter
+what case sensitivity behavior is present, the names of tables in
+foreign key declarations are *always* received from the database
+as all-lower case, making it impossible to accurately reflect a
+schema where inter-related tables use mixed-case identifier names.
+
+Therefore it is strongly advised that table names be declared as
+all lower case both within SQLAlchemy as well as on the MySQL
+database itself, especially if database reflection features are
+to be used.
+
+Transaction Isolation Level
+---------------------------
+
+:func:`.create_engine` accepts an ``isolation_level``
+parameter which results in the command ``SET SESSION
+TRANSACTION ISOLATION LEVEL <level>`` being invoked for
+every new connection. Valid values for this parameter are
+``READ COMMITTED``, ``READ UNCOMMITTED``,
+``REPEATABLE READ``, and ``SERIALIZABLE``::
+
+    engine = create_engine(
+                    "mysql://scott:tiger@localhost/test",
+                    isolation_level="READ UNCOMMITTED"
+                )
+
+.. versionadded:: 0.7.6
+
+AUTO_INCREMENT Behavior
+-----------------------
+
+When creating tables, SQLAlchemy will automatically set ``AUTO_INCREMENT`` on
+the first :class:`.Integer` primary key column which is not marked as a
+foreign key::
+
+  >>> t = Table('mytable', metadata,
+  ...   Column('mytable_id', Integer, primary_key=True)
+  ... )
+  >>> t.create()
+  CREATE TABLE mytable (
+          id INTEGER NOT NULL AUTO_INCREMENT,
+          PRIMARY KEY (id)
+  )
+
+You can disable this behavior by passing ``False`` to the
+:paramref:`~.Column.autoincrement` argument of :class:`.Column`.  This flag
+can also be used to enable auto-increment on a secondary column in a
+multi-column key for some storage engines::
+
+  Table('mytable', metadata,
+        Column('gid', Integer, primary_key=True, autoincrement=False),
+        Column('id', Integer, primary_key=True)
+       )
+
+Ansi Quoting Style
+------------------
+
+MySQL features two varieties of identifier "quoting style", one using
+backticks and the other using quotes, e.g. ```some_identifier```  vs.
+``"some_identifier"``.   All MySQL dialects detect which version
+is in use by checking the value of ``sql_mode`` when a connection is first
+established with a particular :class:`.Engine`.  This quoting style comes
+into play when rendering table and column names as well as when reflecting
+existing database structures.  The detection is entirely automatic and
+no special configuration is needed to use either quoting style.
+
+.. versionchanged:: 0.6 detection of ANSI quoting style is entirely automatic,
+   there's no longer any end-user ``create_engine()`` options in this regard.
+
+MySQL SQL Extensions
+--------------------
+
+Many of the MySQL SQL extensions are handled through SQLAlchemy's generic
+function and operator support::
+
+  table.select(table.c.password==func.md5('plaintext'))
+  table.select(table.c.username.op('regexp')('^[a-d]'))
+
+And of course any valid MySQL statement can be executed as a string as well.
+
+Some limited direct support for MySQL extensions to SQL is currently
+available.
+
+* SELECT pragma::
+
+    select(..., prefixes=['HIGH_PRIORITY', 'SQL_SMALL_RESULT'])
+
+* UPDATE with LIMIT::
+
+    update(..., mysql_limit=10)
+
+rowcount Support
+----------------
+
+SQLAlchemy standardizes the DBAPI ``cursor.rowcount`` attribute to be the
+usual definition of "number of rows matched by an UPDATE or DELETE" statement.
+This is in contradiction to the default setting on most MySQL DBAPI drivers,
+which is "number of rows actually modified/deleted".  For this reason, the
+SQLAlchemy MySQL dialects always set the ``constants.CLIENT.FOUND_ROWS`` flag,
+or whatever is equivalent for the DBAPI in use, on connect, unless the flag
+value is overridden using DBAPI-specific options
+(such as ``client_flag`` for the MySQL-Python driver, ``found_rows`` for the
+OurSQL driver).
+
+See also:
+
+:attr:`.ResultProxy.rowcount`
+
+
+CAST Support
+------------
+
+MySQL documents the CAST operator as available in version 4.0.2.  When using
+the SQLAlchemy :func:`.cast` function, SQLAlchemy
+will not render the CAST token on MySQL before this version, based on server
+version detection, instead rendering the internal expression directly.
+
+CAST may still not be desirable on an early MySQL version post-4.0.2, as it
+didn't add all datatype support until 4.1.1.   If your application falls into
+this narrow area, the behavior of CAST can be controlled using the
+:ref:`sqlalchemy.ext.compiler_toplevel` system, as per the recipe below::
+
+    from sqlalchemy.sql.expression import Cast
+    from sqlalchemy.ext.compiler import compiles
+
+    @compiles(Cast, 'mysql')
+    def _check_mysql_version(element, compiler, **kw):
+        if compiler.dialect.server_version_info < (4, 1, 0):
+            return compiler.process(element.clause, **kw)
+        else:
+            return compiler.visit_cast(element, **kw)
+
+The above function, which only needs to be declared once
+within an application, overrides the compilation of the
+:func:`.cast` construct to check for version 4.1.0 before
+fully rendering CAST; else the internal element of the
+construct is rendered directly.
+
+
+.. _mysql_indexes:
+
+MySQL Specific Index Options
+----------------------------
+
+MySQL-specific extensions to the :class:`.Index` construct are available.
+
+Index Length
+~~~~~~~~~~~~~
+
+MySQL provides an option to create index entries with a certain length, where
+"length" refers to the number of characters or bytes in each value which will
+become part of the index. SQLAlchemy provides this feature via the
+``mysql_length`` parameter::
+
+    Index('my_index', my_table.c.data, mysql_length=10)
+
+    Index('a_b_idx', my_table.c.a, my_table.c.b, mysql_length={'a': 4,
+                                                               'b': 9})
+
+Prefix lengths are given in characters for nonbinary string types and in bytes
+for binary string types. The value passed to the keyword argument *must* be
+either an integer (and, thus, specify the same prefix length value for all
+columns of the index) or a dict in which keys are column names and values are
+prefix length values for corresponding columns. MySQL only allows a length for
+a column of an index if it is for a CHAR, VARCHAR, TEXT, BINARY, VARBINARY and
+BLOB.
+
+.. versionadded:: 0.8.2 ``mysql_length`` may now be specified as a dictionary
+   for use with composite indexes.
+
+Index Types
+~~~~~~~~~~~~~
+
+Some MySQL storage engines permit you to specify an index type when creating
+an index or primary key constraint. SQLAlchemy provides this feature via the
+``mysql_using`` parameter on :class:`.Index`::
+
+    Index('my_index', my_table.c.data, mysql_using='hash')
+
+As well as the ``mysql_using`` parameter on :class:`.PrimaryKeyConstraint`::
+
+    PrimaryKeyConstraint("data", mysql_using='hash')
+
+The value passed to the keyword argument will be simply passed through to the
+underlying CREATE INDEX or PRIMARY KEY clause, so it *must* be a valid index
+type for your MySQL storage engine.
+
+More information can be found at:
+
+http://dev.mysql.com/doc/refman/5.0/en/create-index.html
+
+http://dev.mysql.com/doc/refman/5.0/en/create-table.html
+
+.. _mysql_foreign_keys:
+
+MySQL Foreign Keys
+------------------
+
+MySQL's behavior regarding foreign keys has some important caveats.
+
+Foreign Key Arguments to Avoid
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+MySQL does not support the foreign key arguments "DEFERRABLE", "INITIALLY",
+or "MATCH".  Using the ``deferrable`` or ``initially`` keyword argument with
+:class:`.ForeignKeyConstraint` or :class:`.ForeignKey` will have the effect of
+these keywords being rendered in a DDL expression, which will then raise an
+error on MySQL.  In order to use these keywords on a foreign key while having
+them ignored on a MySQL backend, use a custom compile rule::
+
+    from sqlalchemy.ext.compiler import compiles
+    from sqlalchemy.schema import ForeignKeyConstraint
+
+    @compiles(ForeignKeyConstraint, "mysql")
+    def process(element, compiler, **kw):
+        element.deferrable = element.initially = None
+        return compiler.visit_foreign_key_constraint(element, **kw)
+
+.. versionchanged:: 0.9.0 - the MySQL backend no longer silently ignores
+   the ``deferrable`` or ``initially`` keyword arguments of
+   :class:`.ForeignKeyConstraint` and :class:`.ForeignKey`.
+
+The "MATCH" keyword is in fact more insidious, and is explicitly disallowed
+by SQLAlchemy in conjunction with the MySQL backend.  This argument is
+silently ignored by MySQL, but in addition has the effect of ON UPDATE and ON
+DELETE options also being ignored by the backend.   Therefore MATCH should
+never be used with the MySQL backend; as is the case with DEFERRABLE and
+INITIALLY, custom compilation rules can be used to correct a MySQL
+ForeignKeyConstraint at DDL definition time.
+
+.. versionadded:: 0.9.0 - the MySQL backend will raise a
+   :class:`.CompileError` when the ``match`` keyword is used with
+   :class:`.ForeignKeyConstraint` or :class:`.ForeignKey`.
+
+Reflection of Foreign Key Constraints
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Not all MySQL storage engines support foreign keys.  When using the
+very common ``MyISAM`` MySQL storage engine, the information loaded by table
+reflection will not include foreign keys.  For these tables, you may supply a
+:class:`~sqlalchemy.ForeignKeyConstraint` at reflection time::
+

+
+Unicode
+-------
+
+MySQLdb requires a "charset" parameter to be passed in order for it
+to handle non-ASCII characters correctly.   When this parameter is passed,
+MySQLdb will also implicitly set the "use_unicode" flag to true, which means
+that it will return Python unicode objects instead of bytestrings.
+However, SQLAlchemy's decode process, when C extensions are enabled,
+is orders of magnitude faster than that of MySQLdb as it does not call into
+Python functions to do so.  Therefore, the **recommended URL to use for
+unicode** will include both charset and use_unicode=0::
+
+    create_engine("mysql+mysqldb://user:pass@host/dbname?charset=utf8&use_unicode=0")
+
+As of this writing, MySQLdb only runs on Python 2.   It is not known how
+MySQLdb behaves on Python 3 as far as unicode decoding.
+
+
+Known Issues
+-------------
+
+MySQL-python version 1.2.2 has a serious memory leak related
+to unicode conversion, a feature which is disabled via ``use_unicode=0``.
+It is strongly advised to use the latest version of MySQL-Python.

+.. dialect:: oracle
+    :name: Oracle
+
+    Oracle version 8 through current (11g at the time of this writing) are
+    supported.
+
+Connect Arguments
+-----------------
+
+The dialect supports several :func:`~sqlalchemy.create_engine()` arguments
+which affect the behavior of the dialect regardless of driver in use.
+
+* ``use_ansi`` - Use ANSI JOIN constructs (see the section on Oracle 8).
+  Defaults to ``True``.  If ``False``, Oracle-8 compatible constructs are used
+  for joins.
+
+* ``optimize_limits`` - defaults to ``False``. see the section on
+  LIMIT/OFFSET.
+
+* ``use_binds_for_limits`` - defaults to ``True``.  see the section on
+  LIMIT/OFFSET.
+
+Auto Increment Behavior
+-----------------------
+
+SQLAlchemy Table objects which include integer primary keys are usually
+assumed to have "autoincrementing" behavior, meaning they can generate their
+own primary key values upon INSERT.  Since Oracle has no "autoincrement"
+feature, SQLAlchemy relies upon sequences to produce these values.   With the
+Oracle dialect, *a sequence must always be explicitly specified to enable
+autoincrement*.  This is divergent with the majority of documentation
+examples which assume the usage of an autoincrement-capable database.   To
+specify sequences, use the sqlalchemy.schema.Sequence object which is passed
+to a Column construct::
+
+  t = Table('mytable', metadata,
+        Column('id', Integer, Sequence('id_seq'), primary_key=True),
+        Column(...), ...
+  )
+
+This step is also required when using table reflection, i.e. autoload=True::
+
+  t = Table('mytable', metadata,
+        Column('id', Integer, Sequence('id_seq'), primary_key=True),
+        autoload=True
+  )
+
+Identifier Casing
+-----------------
+
+In Oracle, the data dictionary represents all case insensitive identifier
+names using UPPERCASE text.   SQLAlchemy on the other hand considers an
+all-lower case identifier name to be case insensitive.   The Oracle dialect
+converts all case insensitive identifiers to and from those two formats during
+schema level communication, such as reflection of tables and indexes.   Using
+an UPPERCASE name on the SQLAlchemy side indicates a case sensitive
+identifier, and SQLAlchemy will quote the name - this will cause mismatches
+against data dictionary data received from Oracle, so unless identifier names
+have been truly created as case sensitive (i.e. using quoted names), all
+lowercase names should be used on the SQLAlchemy side.
+
+
+LIMIT/OFFSET Support
+--------------------
+
+Oracle has no support for the LIMIT or OFFSET keywords.  SQLAlchemy uses
+a wrapped subquery approach in conjunction with ROWNUM.  The exact methodology
+is taken from
+http://www.oracle.com/technology/oramag/oracle/06-sep/o56asktom.html .
+
+There are two options which affect its behavior:
+
+* the "FIRST ROWS()" optimization keyword is not used by default.  To enable
+  the usage of this optimization directive, specify ``optimize_limits=True``
+  to :func:`.create_engine`.
+* the values passed for the limit/offset are sent as bound parameters.   Some
+  users have observed that Oracle produces a poor query plan when the values
+  are sent as binds and not rendered literally.   To render the limit/offset
+  values literally within the SQL statement, specify
+  ``use_binds_for_limits=False`` to :func:`.create_engine`.
+
+Some users have reported better performance when the entirely different
+approach of a window query is used, i.e. ROW_NUMBER() OVER (ORDER BY), to
+provide LIMIT/OFFSET (note that the majority of users don't observe this).
+To suit this case the method used for LIMIT/OFFSET can be replaced entirely.
+See the recipe at
+http://www.sqlalchemy.org/trac/wiki/UsageRecipes/WindowFunctionsByDefault
+which installs a select compiler that overrides the generation of limit/offset
+with a window function.

+.. _oracle_returning:
+
+RETURNING Support
+-----------------
+
+The Oracle database supports a limited form of RETURNING, in order to retrieve
+result sets of matched rows from INSERT, UPDATE and DELETE statements.
+Oracle's RETURNING..INTO syntax only supports one row being returned, as it
+relies upon OUT parameters in order to function.  In addition, supported
+DBAPIs have further limitations (see :ref:`cx_oracle_returning`).
+
+SQLAlchemy's "implicit returning" feature, which employs RETURNING within an
+INSERT and sometimes an UPDATE statement in order to fetch newly generated
+primary key values and other SQL defaults and expressions, is normally enabled
+on the Oracle backend.  By default, "implicit returning" typically only
+fetches the value of a single ``nextval(some_seq)`` expression embedded into
+an INSERT in order to increment a sequence within an INSERT statement and get
+the value back at the same time. To disable this feature across the board,
+specify ``implicit_returning=False`` to :func:`.create_engine`::
+
+    engine = create_engine("oracle://scott:tiger@dsn",
+                           implicit_returning=False)
+
+Implicit returning can also be disabled on a table-by-table basis as a table
+option::
+
+    # Core Table
+    my_table = Table("my_table", metadata, ..., implicit_returning=False)
+
+
+    # declarative
+    class MyClass(Base):
+        __tablename__ = 'my_table'
+        __table_args__ = {"implicit_returning": False}
+
+.. seealso::
+
+    :ref:`cx_oracle_returning` - additional cx_oracle-specific restrictions on
+    implicit returning.
+
+ON UPDATE CASCADE
+-----------------
+
+Oracle doesn't have native ON UPDATE CASCADE functionality.  A trigger based
+solution is available at
+http://asktom.oracle.com/tkyte/update_cascade/index.html .
+
+When using the SQLAlchemy ORM, the ORM has limited ability to manually issue
+cascading updates - specify ForeignKey objects using the
+"deferrable=True, initially='deferred'" keyword arguments,
+and specify "passive_updates=False" on each relationship().
+
+Oracle 8 Compatibility
+----------------------
+
+When Oracle 8 is detected, the dialect internally configures itself to the
+following behaviors:
+
+* the use_ansi flag is set to False.  This has the effect of converting all
+  JOIN phrases into the WHERE clause, and in the case of LEFT OUTER JOIN
+  makes use of Oracle's (+) operator.
+
+* the NVARCHAR2 and NCLOB datatypes are no longer generated as DDL when
+  the :class:`~sqlalchemy.types.Unicode` is used - VARCHAR2 and CLOB are
+  issued instead.   This because these types don't seem to work correctly on
+  Oracle 8 even though they are available.  The
+  :class:`~sqlalchemy.types.NVARCHAR` and
+  :class:`~sqlalchemy.dialects.oracle.NCLOB` types will always generate
+  NVARCHAR2 and NCLOB.
+
+* the "native unicode" mode is disabled when using cx_oracle, i.e. SQLAlchemy
+  encodes all Python unicode objects to "string" before passing in as bind
+  parameters.
+
+Synonym/DBLINK Reflection
+-------------------------
+
+When using reflection with Table objects, the dialect can optionally search
+for tables indicated by synonyms, either in local or remote schemas or
+accessed over DBLINK, by passing the flag ``oracle_resolve_synonyms=True`` as
+a keyword argument to the :class:`.Table` construct::
+
+    some_table = Table('some_table', autoload=True,
+                                autoload_with=some_engine,
+                                oracle_resolve_synonyms=True)
+
+When this flag is set, the given name (such as ``some_table`` above) will
+be searched not just in the ``ALL_TABLES`` view, but also within the
+``ALL_SYNONYMS`` view to see if this name is actually a synonym to another
+name.  If the synonym is located and refers to a DBLINK, the oracle dialect
+knows how to locate the table's information using DBLINK syntax(e.g.
+``@dblink``).
+
+``oracle_resolve_synonyms`` is accepted wherever reflection arguments are
+accepted, including methods such as :meth:`.MetaData.reflect` and
+:meth:`.Inspector.get_columns`.
+
+If synonyms are not in use, this flag should be left disabled.
+
+DateTime Compatibility
+----------------------
+
+Oracle has no datatype known as ``DATETIME``, it instead has only ``DATE``,
+which can actually store a date and time value.  For this reason, the Oracle
+dialect provides a type :class:`.oracle.DATE` which is a subclass of
+:class:`.DateTime`.   This type has no special behavior, and is only
+present as a "marker" for this type; additionally, when a database column
+is reflected and the type is reported as ``DATE``, the time-supporting
+:class:`.oracle.DATE` type is used.
+
+.. versionchanged:: 0.9.4 Added :class:`.oracle.DATE` to subclass
+   :class:`.DateTime`.  This is a change as previous versions
+   would reflect a ``DATE`` column as :class:`.types.DATE`, which subclasses
+   :class:`.Date`.   The only significance here is for schemes that are
+   examining the type of column for use in special Python translations or
+   for migrating schemas to other database backends.

+
+Additional Connect Arguments
+----------------------------
+
+When connecting with ``dbname`` present, the host, port, and dbname tokens are
+converted to a TNS name using
+the cx_oracle ``makedsn()`` function.  Otherwise, the host token is taken
+directly as a TNS name.
+
+Additional arguments which may be specified either as query string arguments
+on the URL, or as keyword arguments to :func:`.create_engine()` are:
+
+* ``allow_twophase`` - enable two-phase transactions.  Defaults to ``True``.
+
+* ``arraysize`` - set the cx_oracle.arraysize value on cursors, defaulted
+  to 50.  This setting is significant with cx_Oracle as the contents of LOB
+  objects are only readable within a "live" row (e.g. within a batch of
+  50 rows).
+
+* ``auto_convert_lobs`` - defaults to True; See :ref:`cx_oracle_lob`.
+
+* ``auto_setinputsizes`` - the cx_oracle.setinputsizes() call is issued for
+  all bind parameters.  This is required for LOB datatypes but can be
+  disabled to reduce overhead.  Defaults to ``True``.  Specific types
+  can be excluded from this process using the ``exclude_setinputsizes``
+  parameter.
+
+* ``coerce_to_unicode`` - see :ref:`cx_oracle_unicode` for detail.
+
+* ``coerce_to_decimal`` - see :ref:`cx_oracle_numeric` for detail.
+
+* ``exclude_setinputsizes`` - a tuple or list of string DBAPI type names to
+  be excluded from the "auto setinputsizes" feature.  The type names here
+  must match DBAPI types that are found in the "cx_Oracle" module namespace,
+  such as cx_Oracle.UNICODE, cx_Oracle.NCLOB, etc.   Defaults to
+  ``(STRING, UNICODE)``.
+
+  .. versionadded:: 0.8 specific DBAPI types can be excluded from the
+     auto_setinputsizes feature via the exclude_setinputsizes attribute.
+
+* ``mode`` - This is given the string value of SYSDBA or SYSOPER, or
+  alternatively an integer value.  This value is only available as a URL query
+  string argument.
+
+* ``threaded`` - enable multithreaded access to cx_oracle connections.
+  Defaults to ``True``.  Note that this is the opposite default of the
+  cx_Oracle DBAPI itself.
+
+.. _cx_oracle_unicode:
+
+Unicode
+-------
+
+The cx_Oracle DBAPI as of version 5 fully supports unicode, and has the
+ability to return string results as Python unicode objects natively.
+
+When used in Python 3, cx_Oracle returns all strings as Python unicode objects
+(that is, plain ``str`` in Python 3).  In Python 2, it will return as Python
+unicode those column values that are of type ``NVARCHAR`` or ``NCLOB``.  For
+column values that are of type ``VARCHAR`` or other non-unicode string types,
+it will return values as Python strings (e.g. bytestrings).
+
+The cx_Oracle SQLAlchemy dialect presents two different options for the use
+case of returning ``VARCHAR`` column values as Python unicode objects under
+Python 2:
+
+* the cx_Oracle DBAPI has the ability to coerce all string results to Python
+  unicode objects unconditionally using output type handlers.  This has
+  the advantage that the unicode conversion is global to all statements
+  at the cx_Oracle driver level, meaning it works with raw textual SQL
+  statements that have no typing information associated.  However, this system
+  has been observed to incur signfiicant performance overhead, not only
+  because it takes effect for all string values unconditionally, but also
+  because cx_Oracle under Python 2 seems to use a pure-Python function call in
+  order to do the decode operation, which under cPython can orders of
+  magnitude slower than doing it using C functions alone.
+
+* SQLAlchemy has unicode-decoding services built in, and when using
+  SQLAlchemy's C extensions, these functions do not use any Python function
+  calls and are very fast.  The disadvantage to this approach is that the
+  unicode conversion only takes effect for statements where the
+  :class:`.Unicode` type or :class:`.String` type with
+  ``convert_unicode=True`` is explicitly associated with the result column.
+  This is the case for any ORM or Core query or SQL expression as well as for
+  a :func:`.text` construct that specifies output column types, so in the vast
+  majority of cases this is not an issue. However, when sending a completely
+  raw string to :meth:`.Connection.execute`, this typing information isn't
+  present, unless the string is handled within a :func:`.text` construct that
+  adds typing information.
+
+As of version 0.9.2 of SQLAlchemy, the default approach is to use SQLAlchemy's
+typing system.  This keeps cx_Oracle's expensive Python 2 approach
+disabled unless the user explicitly wants it.  Under Python 3, SQLAlchemy
+detects that cx_Oracle is returning unicode objects natively and cx_Oracle's
+system is used.
+
+To re-enable cx_Oracle's output type handler under Python 2, the
+``coerce_to_unicode=True`` flag (new in 0.9.4) can be passed to
+:func:`.create_engine`::
+
+    engine = create_engine("oracle+cx_oracle://dsn", coerce_to_unicode=True)
+
+Alternatively, to run a pure string SQL statement and get ``VARCHAR`` results
+as Python unicode under Python 2 without using cx_Oracle's native handlers,
+the :func:`.text` feature can be used::
+
+    from sqlalchemy import text, Unicode
+    result = conn.execute(
+        text("select username from user").columns(username=Unicode))
+
+.. versionchanged:: 0.9.2 cx_Oracle's outputtypehandlers are no longer used
+   for unicode results of non-unicode datatypes in Python 2, after they were
+   identified as a major performance bottleneck.  SQLAlchemy's own unicode
+   facilities are used instead.
+
+.. versionadded:: 0.9.4 Added the ``coerce_to_unicode`` flag, to re-enable
+   cx_Oracle's outputtypehandler and revert to pre-0.9.2 behavior.
+
+.. _cx_oracle_returning:
+
+RETURNING Support
+-----------------
+
+The cx_oracle DBAPI supports a limited subset of Oracle's already limited
+RETURNING support.  Typically, results can only be guaranteed for at most one
+column being returned; this is the typical case when SQLAlchemy uses RETURNING
+to get just the value of a primary-key-associated sequence value.
+Additional column expressions will cause problems in a non-determinative way,
+due to cx_oracle's lack of support for the OCI_DATA_AT_EXEC API which is
+required for more complex RETURNING scenarios.
+
+For this reason, stability may be enhanced by disabling RETURNING support
+completely; SQLAlchemy otherwise will use RETURNING to fetch newly
+sequence-generated primary keys.  As illustrated in :ref:`oracle_returning`::
+
+    engine = create_engine("oracle://scott:tiger@dsn",
+                           implicit_returning=False)
+
+.. seealso::
+
+    http://docs.oracle.com/cd/B10501_01/appdev.920/a96584/oci05bnd.htm#420693
+    - OCI documentation for RETURNING

+    http://sourceforge.net/mailarchive/message.php?msg_id=31338136
+    - cx_oracle developer commentary
+
+.. _cx_oracle_lob:
+
+LOB Objects
+-----------
+
+cx_oracle returns oracle LOBs using the cx_oracle.LOB object.  SQLAlchemy
+converts these to strings so that the interface of the Binary type is
+consistent with that of other backends, and so that the linkage to a live
+cursor is not needed in scenarios like result.fetchmany() and
+result.fetchall().   This means that by default, LOB objects are fully fetched
+unconditionally by SQLAlchemy, and the linkage to a live cursor is broken.
+
+To disable this processing, pass ``auto_convert_lobs=False`` to
+:func:`.create_engine()`.
+
+Two Phase Transaction Support
+-----------------------------
+
+Two Phase transactions are implemented using XA transactions, and are known
+to work in a rudimental fashion with recent versions of cx_Oracle
+as of SQLAlchemy 0.8.0b2, 0.7.10.   However, the mechanism is not yet
+considered to be robust and should still be regarded as experimental.
+
+In particular, the cx_Oracle DBAPI as recently as 5.1.2 has a bug regarding
+two phase which prevents
+a particular DBAPI connection from being consistently usable in both
+prepared transactions as well as traditional DBAPI usage patterns; therefore
+once a particular connection is used via :meth:`.Connection.begin_prepared`,
+all subsequent usages of the underlying DBAPI connection must be within
+the context of prepared transactions.
+
+The default behavior of :class:`.Engine` is to maintain a pool of DBAPI
+connections.  Therefore, due to the above glitch, a DBAPI connection that has
+been used in a two-phase operation, and is then returned to the pool, will
+not be usable in a non-two-phase context.   To avoid this situation,
+the application can make one of several choices:
+
+* Disable connection pooling using :class:`.NullPool`
+
+* Ensure that the particular :class:`.Engine` in use is only used
+  for two-phase operations.   A :class:`.Engine` bound to an ORM
+  :class:`.Session` which includes ``twophase=True`` will consistently
+  use the two-phase transaction style.
+
+* For ad-hoc two-phase operations without disabling pooling, the DBAPI
+  connection in use can be evicted from the connection pool using the
+  :meth:`.Connection.detach` method.
+
+.. versionchanged:: 0.8.0b2,0.7.10
+    Support for cx_oracle prepared transactions has been implemented
+    and tested.
+
+.. _cx_oracle_numeric:
+
+Precision Numerics
+------------------
+
+The SQLAlchemy dialect goes through a lot of steps to ensure
+that decimal numbers are sent and received with full accuracy.
+An "outputtypehandler" callable is associated with each
+cx_oracle connection object which detects numeric types and
+receives them as string values, instead of receiving a Python
+``float`` directly, which is then passed to the Python
+``Decimal`` constructor.  The :class:`.Numeric` and
+:class:`.Float` types under the cx_oracle dialect are aware of
+this behavior, and will coerce the ``Decimal`` to ``float`` if
+the ``asdecimal`` flag is ``False`` (default on :class:`.Float`,
+optional on :class:`.Numeric`).
+
+Because the handler coerces to ``Decimal`` in all cases first,
+the feature can detract significantly from performance.
+If precision numerics aren't required, the decimal handling
+can be disabled by passing the flag ``coerce_to_decimal=False``
+to :func:`.create_engine`::
+
+    engine = create_engine("oracle+cx_oracle://dsn", coerce_to_decimal=False)
+
+.. versionadded:: 0.7.6
+    Add the ``coerce_to_decimal`` flag.
+
+Another alternative to performance is to use the
+`cdecimal <http://pypi.python.org/pypi/cdecimal/>`_ library;
+see :class:`.Numeric` for additional notes.
+
+The handler attempts to use the "precision" and "scale"
+attributes of the result set column to best determine if
+subsequent incoming values should be received as ``Decimal`` as
+opposed to int (in which case no processing is added). There are
+several scenarios where OCI_ does not provide unambiguous data
+as to the numeric type, including some situations where
+individual rows may return a combination of floating point and
+integer values. Certain values for "precision" and "scale" have
+been observed to determine this scenario.  When it occurs, the
+outputtypehandler receives as string and then passes off to a
+processing function which detects, for each returned value, if a
+decimal point is present, and if so converts to ``Decimal``,
+otherwise to int.  The intention is that simple int-based
+statements like "SELECT my_seq.nextval() FROM DUAL" continue to
+return ints and not ``Decimal`` objects, and that any kind of
+floating point value is received as a string so that there is no
+floating point loss of precision.
+
+The "decimal point is present" logic itself is also sensitive to
+locale.  Under OCI_, this is controlled by the NLS_LANG
+environment variable. Upon first connection, the dialect runs a
+test to determine the current "decimal" character, which can be
+a comma "," for European locales. From that point forward the
+outputtypehandler uses that character to represent a decimal
+point. Note that cx_oracle 5.0.3 or greater is required
+when dealing with numerics with locale settings that don't use
+a period "." as the decimal character.
+
+.. versionchanged:: 0.6.6
+    The outputtypehandler supports the case where the locale uses a
+    comma "," character to represent a decimal point.

+.. dialect:: postgresql
+    :name: PostgreSQL
+
+
+Sequences/SERIAL
+----------------
+
+PostgreSQL supports sequences, and SQLAlchemy uses these as the default means
+of creating new primary key values for integer-based primary key columns. When
+creating tables, SQLAlchemy will issue the ``SERIAL`` datatype for
+integer-based primary key columns, which generates a sequence and server side
+default corresponding to the column.
+
+To specify a specific named sequence to be used for primary key generation,
+use the :func:`~sqlalchemy.schema.Sequence` construct::
+
+    Table('sometable', metadata,
+            Column('id', Integer, Sequence('some_id_seq'), primary_key=True)
+        )
+
+When SQLAlchemy issues a single INSERT statement, to fulfill the contract of
+having the "last insert identifier" available, a RETURNING clause is added to
+the INSERT statement which specifies the primary key columns should be
+returned after the statement completes. The RETURNING functionality only takes
+place if Postgresql 8.2 or later is in use. As a fallback approach, the
+sequence, whether specified explicitly or implicitly via ``SERIAL``, is
+executed independently beforehand, the returned value to be used in the
+subsequent insert. Note that when an
+:func:`~sqlalchemy.sql.expression.insert()` construct is executed using
+"executemany" semantics, the "last inserted identifier" functionality does not
+apply; no RETURNING clause is emitted nor is the sequence pre-executed in this
+case.
+
+To force the usage of RETURNING by default off, specify the flag
+``implicit_returning=False`` to :func:`.create_engine`.
+
+.. _postgresql_isolation_level:
+
+Transaction Isolation Level
+---------------------------
+
+All Postgresql dialects support setting of transaction isolation level
+both via a dialect-specific parameter ``isolation_level``
+accepted by :func:`.create_engine`,
+as well as the ``isolation_level`` argument as passed to
+:meth:`.Connection.execution_options`.  When using a non-psycopg2 dialect,
+this feature works by issuing the command
+``SET SESSION CHARACTERISTICS AS TRANSACTION ISOLATION LEVEL <level>`` for
+each new connection.
+
+To set isolation level using :func:`.create_engine`::
+
+    engine = create_engine(
+        "postgresql+pg8000://scott:tiger@localhost/test",
+        isolation_level="READ UNCOMMITTED"
+    )
+
+To set using per-connection execution options::
+
+    connection = engine.connect()
+    connection = connection.execution_options(
+        isolation_level="READ COMMITTED"
+    )
+
+Valid values for ``isolation_level`` include:
+
+* ``READ COMMITTED``
+* ``READ UNCOMMITTED``
+* ``REPEATABLE READ``
+* ``SERIALIZABLE``
+
+The :mod:`~sqlalchemy.dialects.postgresql.psycopg2` and
+:mod:`~sqlalchemy.dialects.postgresql.pg8000` dialects also offer the
+special level ``AUTOCOMMIT``.
+
+.. seealso::
+
+    :ref:`psycopg2_isolation_level`
+
+    :ref:`pg8000_isolation_level`
+
+.. _postgresql_schema_reflection:
+
+Remote-Schema Table Introspection and Postgresql search_path
+------------------------------------------------------------
+
+The Postgresql dialect can reflect tables from any schema.  The
+:paramref:`.Table.schema` argument, or alternatively the
+:paramref:`.MetaData.reflect.schema` argument determines which schema will
+be searched for the table or tables.   The reflected :class:`.Table` objects
+will in all cases retain this ``.schema`` attribute as was specified.
+However, with regards to tables which these :class:`.Table` objects refer to
+via foreign key constraint, a decision must be made as to how the ``.schema``
+is represented in those remote tables, in the case where that remote
+schema name is also a member of the current
+`Postgresql search path
+<http://www.postgresql.org/docs/9.0/static/ddl-schemas.html#DDL-SCHEMAS-PATH>`_.
+
+By default, the Postgresql dialect mimics the behavior encouraged by
+Postgresql's own ``pg_get_constraintdef()`` builtin procedure.  This function
+returns a sample definition for a particular foreign key constraint,
+omitting the referenced schema name from that definition when the name is
+also in the Postgresql schema search path.  The interaction below
+illustrates this behavior::
+
+    test=> CREATE TABLE test_schema.referred(id INTEGER PRIMARY KEY);
+    CREATE TABLE
+    test=> CREATE TABLE referring(
+    test(>         id INTEGER PRIMARY KEY,
+    test(>         referred_id INTEGER REFERENCES test_schema.referred(id));
+    CREATE TABLE
+    test=> SET search_path TO public, test_schema;
+    test=> SELECT pg_catalog.pg_get_constraintdef(r.oid, true) FROM
+    test-> pg_catalog.pg_class c JOIN pg_catalog.pg_namespace n
+    test-> ON n.oid = c.relnamespace
+    test-> JOIN pg_catalog.pg_constraint r  ON c.oid = r.conrelid
+    test-> WHERE c.relname='referring' AND r.contype = 'f'
+    test-> ;
+                   pg_get_constraintdef
+    ---------------------------------------------------
+     FOREIGN KEY (referred_id) REFERENCES referred(id)
+    (1 row)
+
+Above, we created a table ``referred`` as a member of the remote schema
+``test_schema``, however when we added ``test_schema`` to the
+PG ``search_path`` and then asked ``pg_get_constraintdef()`` for the
+``FOREIGN KEY`` syntax, ``test_schema`` was not included in the output of
+the function.
+
+On the other hand, if we set the search path back to the typical default
+of ``public``::
+
+    test=> SET search_path TO public;
+    SET
+
+The same query against ``pg_get_constraintdef()`` now returns the fully
+schema-qualified name for us::
+
+    test=> SELECT pg_catalog.pg_get_constraintdef(r.oid, true) FROM
+    test-> pg_catalog.pg_class c JOIN pg_catalog.pg_namespace n
+    test-> ON n.oid = c.relnamespace
+    test-> JOIN pg_catalog.pg_constraint r  ON c.oid = r.conrelid
+    test-> WHERE c.relname='referring' AND r.contype = 'f';
+                         pg_get_constraintdef
+    ---------------------------------------------------------------
+     FOREIGN KEY (referred_id) REFERENCES test_schema.referred(id)
+    (1 row)
+
+SQLAlchemy will by default use the return value of ``pg_get_constraintdef()``
+in order to determine the remote schema name.  That is, if our ``search_path``
+were set to include ``test_schema``, and we invoked a table
+reflection process as follows::
+
+    >>> from sqlalchemy import Table, MetaData, create_engine
+    >>> engine = create_engine("postgresql://scott:tiger@localhost/test")
+    >>> with engine.connect() as conn:
+    ...     conn.execute("SET search_path TO test_schema, public")
+    ...     meta = MetaData()
+    ...     referring = Table('referring', meta,
+    ...                       autoload=True, autoload_with=conn)
+    ...
+    <sqlalchemy.engine.result.ResultProxy object at 0x101612ed0>
+
+The above process would deliver to the :attr:`.MetaData.tables` collection
+``referred`` table named **without** the schema::
+
+    >>> meta.tables['referred'].schema is None
+    True
+
+To alter the behavior of reflection such that the referred schema is
+maintained regardless of the ``search_path`` setting, use the
+``postgresql_ignore_search_path`` option, which can be specified as a
+dialect-specific argument to both :class:`.Table` as well as
+:meth:`.MetaData.reflect`::
+
+    >>> with engine.connect() as conn:
+    ...     conn.execute("SET search_path TO test_schema, public")
+    ...     meta = MetaData()
+    ...     referring = Table('referring', meta, autoload=True,
+    ...                       autoload_with=conn,
+    ...                       postgresql_ignore_search_path=True)
+    ...
+    <sqlalchemy.engine.result.ResultProxy object at 0x1016126d0>
+
+We will now have ``test_schema.referred`` stored as schema-qualified::
+
+    >>> meta.tables['test_schema.referred'].schema
+    'test_schema'
+
+.. sidebar:: Best Practices for Postgresql Schema reflection
+
+    The description of Postgresql schema reflection behavior is complex, and
+    is the product of many years of dealing with widely varied use cases and
+    user preferences. But in fact, there's no need to understand any of it if
+    you just stick to the simplest use pattern: leave the ``search_path`` set
+    to its default of ``public`` only, never refer to the name ``public`` as
+    an explicit schema name otherwise, and refer to all other schema names
+    explicitly when building up a :class:`.Table` object.  The options
+    described here are only for those users who can't, or prefer not to, stay
+    within these guidelines.
+
+Note that **in all cases**, the "default" schema is always reflected as
+``None``. The "default" schema on Postgresql is that which is returned by the
+Postgresql ``current_schema()`` function.  On a typical Postgresql
+installation, this is the name ``public``.  So a table that refers to another
+which is in the ``public`` (i.e. default) schema will always have the
+``.schema`` attribute set to ``None``.
+
+.. versionadded:: 0.9.2 Added the ``postgresql_ignore_search_path``
+   dialect-level option accepted by :class:`.Table` and
+   :meth:`.MetaData.reflect`.
+
+
+.. seealso::
+
+        `The Schema Search Path
+        <http://www.postgresql.org/docs/9.0/static/ddl-schemas.html#DDL-SCHEMAS-PATH>`_

+
+INSERT/UPDATE...RETURNING
+-------------------------
+
+The dialect supports PG 8.2's ``INSERT..RETURNING``, ``UPDATE..RETURNING`` and
+``DELETE..RETURNING`` syntaxes.   ``INSERT..RETURNING`` is used by default
+for single-row INSERT statements in order to fetch newly generated
+primary key identifiers.   To specify an explicit ``RETURNING`` clause,
+use the :meth:`._UpdateBase.returning` method on a per-statement basis::
+
+    # INSERT..RETURNING
+    result = table.insert().returning(table.c.col1, table.c.col2).\\
+        values(name='foo')
+    print result.fetchall()
+
+    # UPDATE..RETURNING
+    result = table.update().returning(table.c.col1, table.c.col2).\\
+        where(table.c.name=='foo').values(name='bar')
+    print result.fetchall()
+
+    # DELETE..RETURNING
+    result = table.delete().returning(table.c.col1, table.c.col2).\\
+        where(table.c.name=='foo')
+    print result.fetchall()
+
+.. _postgresql_match:
+
+Full Text Search
+----------------
+
+SQLAlchemy makes available the Postgresql ``@@`` operator via the
+:meth:`.ColumnElement.match` method on any textual column expression.
+On a Postgresql dialect, an expression like the following::
+
+    select([sometable.c.text.match("search string")])
+
+will emit to the database::
+
+    SELECT text @@ to_tsquery('search string') FROM table
+
+The Postgresql text search functions such as ``to_tsquery()``
+and ``to_tsvector()`` are available
+explicitly using the standard :attr:`.func` construct.  For example::
+
+    select([
+        func.to_tsvector('fat cats ate rats').match('cat & rat')
+    ])
+
+Emits the equivalent of::
+
+    SELECT to_tsvector('fat cats ate rats') @@ to_tsquery('cat & rat')
+
+The :class:`.postgresql.TSVECTOR` type can provide for explicit CAST::
+
+    from sqlalchemy.dialects.postgresql import TSVECTOR
+    from sqlalchemy import select, cast
+    select([cast("some text", TSVECTOR)])
+
+produces a statement equivalent to::
+
+    SELECT CAST('some text' AS TSVECTOR) AS anon_1
+
+Full Text Searches in Postgresql are influenced by a combination of: the
+PostgresSQL setting of ``default_text_search_config``, the ``regconfig`` used
+to build the GIN/GiST indexes, and the ``regconfig`` optionally passed in
+during a query.
+
+When performing a Full Text Search against a column that has a GIN or
+GiST index that is already pre-computed (which is common on full text
+searches) one may need to explicitly pass in a particular PostgresSQL
+``regconfig`` value to ensure the query-planner utilizes the index and does
+not re-compute the column on demand.
+
+In order to provide for this explicit query planning, or to use different
+search strategies, the ``match`` method accepts a ``postgresql_regconfig``
+keyword argument.
+
+    select([mytable.c.id]).where(
+        mytable.c.title.match('somestring', postgresql_regconfig='english')
+    )
+
+Emits the equivalent of::
+
+    SELECT mytable.id FROM mytable
+    WHERE mytable.title @@ to_tsquery('english', 'somestring')
+
+One can also specifically pass in a `'regconfig'` value to the
+``to_tsvector()`` command as the initial argument.
+
+    select([mytable.c.id]).where(
+            func.to_tsvector('english', mytable.c.title )\
+            .match('somestring', postgresql_regconfig='english')
+        )
+
+produces a statement equivalent to::
+
+    SELECT mytable.id FROM mytable
+    WHERE to_tsvector('english', mytable.title) @@
+        to_tsquery('english', 'somestring')
+
+It is recommended that you use the ``EXPLAIN ANALYZE...`` tool from
+PostgresSQL to ensure that you are generating queries with SQLAlchemy that
+take full advantage of any indexes you may have created for full text search.
+
+FROM ONLY ...
+------------------------
+
+The dialect supports PostgreSQL's ONLY keyword for targeting only a particular
+table in an inheritance hierarchy. This can be used to produce the
+``SELECT ... FROM ONLY``, ``UPDATE ONLY ...``, and ``DELETE FROM ONLY ...``
+syntaxes. It uses SQLAlchemy's hints mechanism::
+
+    # SELECT ... FROM ONLY ...
+    result = table.select().with_hint(table, 'ONLY', 'postgresql')
+    print result.fetchall()
+
+    # UPDATE ONLY ...
+    table.update(values=dict(foo='bar')).with_hint('ONLY',
+                                                   dialect_name='postgresql')
+
+    # DELETE FROM ONLY ...
+    table.delete().with_hint('ONLY', dialect_name='postgresql')
+
+.. _postgresql_indexes:
+
+Postgresql-Specific Index Options
+---------------------------------
+
+Several extensions to the :class:`.Index` construct are available, specific
+to the PostgreSQL dialect.
+
+Partial Indexes
+^^^^^^^^^^^^^^^^
+
+Partial indexes add criterion to the index definition so that the index is
+applied to a subset of rows.   These can be specified on :class:`.Index`
+using the ``postgresql_where`` keyword argument::
+
+  Index('my_index', my_table.c.id, postgresql_where=tbl.c.value > 10)
+
+Operator Classes
+^^^^^^^^^^^^^^^^^
+
+PostgreSQL allows the specification of an *operator class* for each column of
+an index (see
+http://www.postgresql.org/docs/8.3/interactive/indexes-opclass.html).
+The :class:`.Index` construct allows these to be specified via the
+``postgresql_ops`` keyword argument::
+
+    Index('my_index', my_table.c.id, my_table.c.data,
+                            postgresql_ops={
+                                'data': 'text_pattern_ops',
+                                'id': 'int4_ops'
+                            })
+
+.. versionadded:: 0.7.2
+    ``postgresql_ops`` keyword argument to :class:`.Index` construct.
+
+Note that the keys in the ``postgresql_ops`` dictionary are the "key" name of
+the :class:`.Column`, i.e. the name used to access it from the ``.c``
+collection of :class:`.Table`, which can be configured to be different than
+the actual name of the column as expressed in the database.
+
+Index Types
+^^^^^^^^^^^^
+
+PostgreSQL provides several index types: B-Tree, Hash, GiST, and GIN, as well
+as the ability for users to create their own (see
+http://www.postgresql.org/docs/8.3/static/indexes-types.html). These can be
+specified on :class:`.Index` using the ``postgresql_using`` keyword argument::
+
+    Index('my_index', my_table.c.data, postgresql_using='gin')
+
+The value passed to the keyword argument will be simply passed through to the
+underlying CREATE INDEX command, so it *must* be a valid index type for your
+version of PostgreSQL.

+Unicode
+-------
+
+When communicating with the server, pg8000 **always uses the server-side
+character set**.  SQLAlchemy has no ability to modify what character set
+pg8000 chooses to use, and additionally SQLAlchemy does no unicode conversion
+of any kind with the pg8000 backend. The origin of the client encoding setting
+is ultimately the CLIENT_ENCODING setting in postgresql.conf.
+
+It is not necessary, though is also harmless, to pass the "encoding" parameter
+to :func:`.create_engine` when using pg8000.

+psycopg2 Connect Arguments
+-----------------------------------
+
+psycopg2-specific keyword arguments which are accepted by

+
+* ``server_side_cursors``: Enable the usage of "server side cursors" for SQL
+  statements which support this feature. What this essentially means from a
+  psycopg2 point of view is that the cursor is created using a name, e.g.
+  ``connection.cursor('some name')``, which has the effect that result rows
+  are not immediately pre-fetched and buffered after statement execution, but
+  are instead left on the server and only retrieved as needed. SQLAlchemy's
+  :class:`~sqlalchemy.engine.ResultProxy` uses special row-buffering
+  behavior when this feature is enabled, such that groups of 100 rows at a
+  time are fetched over the wire to reduce conversational overhead.
+  Note that the ``stream_results=True`` execution option is a more targeted
+  way of enabling this mode on a per-execution basis.
+* ``use_native_unicode``: Enable the usage of Psycopg2 "native unicode" mode
+  per connection.  True by default.
+* ``isolation_level``: This option, available for all PostgreSQL dialects,
+  includes the ``AUTOCOMMIT`` isolation level when using the psycopg2
+  dialect.  See :ref:`psycopg2_isolation_level`.
+
+
+Unix Domain Connections
+------------------------
+
+psycopg2 supports connecting via Unix domain connections.   When the ``host``
+portion of the URL is omitted, SQLAlchemy passes ``None`` to psycopg2,
+which specifies Unix-domain communication rather than TCP/IP communication::
+
+    create_engine("postgresql+psycopg2://user:password@/dbname")
+
+By default, the socket file used is to connect to a Unix-domain socket
+in ``/tmp``, or whatever socket directory was specified when PostgreSQL
+was built.  This value can be overridden by passing a pathname to psycopg2,
+using ``host`` as an additional keyword argument::
+
+    create_engine("postgresql+psycopg2://user:password@/dbname?host=/var/lib/postgresql")
+
+See also:
+
+`PQconnectdbParams <http://www.postgresql.org/docs/9.1/static\
+/libpq-connect.html#LIBPQ-PQCONNECTDBPARAMS>`_
+
+Per-Statement/Connection Execution Options
+-------------------------------------------
+
+The following DBAPI-specific options are respected when used with
+:meth:`.Connection.execution_options`, :meth:`.Executable.execution_options`,
+:meth:`.Query.execution_options`, in addition to those not specific to DBAPIs:
+
+* isolation_level - Set the transaction isolation level for the lifespan of a
+  :class:`.Connection` (can only be set on a connection, not a statement
+  or query).   See :ref:`psycopg2_isolation_level`.
+
+* stream_results - Enable or disable usage of psycopg2 server side cursors -
+  this feature makes use of "named" cursors in combination with special
+  result handling methods so that result rows are not fully buffered.
+  If ``None`` or not set, the ``server_side_cursors`` option of the
+  :class:`.Engine` is used.
+
+Unicode
+-------
+
+By default, the psycopg2 driver uses the ``psycopg2.extensions.UNICODE``
+extension, such that the DBAPI receives and returns all strings as Python
+Unicode objects directly - SQLAlchemy passes these values through without
+change.   Psycopg2 here will encode/decode string values based on the
+current "client encoding" setting; by default this is the value in
+the ``postgresql.conf`` file, which often defaults to ``SQL_ASCII``.
+Typically, this can be changed to ``utf-8``, as a more useful default::
+
+    #client_encoding = sql_ascii # actually, defaults to database
+                                 # encoding
+    client_encoding = utf8
+
+A second way to affect the client encoding is to set it within Psycopg2
+locally.   SQLAlchemy will call psycopg2's ``set_client_encoding()``
+method (see:
+http://initd.org/psycopg/docs/connection.html#connection.set_client_encoding)
+on all new connections based on the value passed to
+:func:`.create_engine` using the ``client_encoding`` parameter::
+
+    engine = create_engine("postgresql://user:pass@host/dbname",
+                           client_encoding='utf8')
+
+This overrides the encoding specified in the Postgresql client configuration.
+
+.. versionadded:: 0.7.3
+    The psycopg2-specific ``client_encoding`` parameter to
+    :func:`.create_engine`.
+
+SQLAlchemy can also be instructed to skip the usage of the psycopg2
+``UNICODE`` extension and to instead utilize its own unicode encode/decode
+services, which are normally reserved only for those DBAPIs that don't
+fully support unicode directly.  Passing ``use_native_unicode=False`` to
+:func:`.create_engine` will disable usage of ``psycopg2.extensions.UNICODE``.
+SQLAlchemy will instead encode data itself into Python bytestrings on the way
+in and coerce from bytes on the way back,
+using the value of the :func:`.create_engine` ``encoding`` parameter, which
+defaults to ``utf-8``.
+SQLAlchemy's own unicode encode/decode functionality is steadily becoming
+obsolete as more DBAPIs support unicode fully along with the approach of
+Python 3; in modern usage psycopg2 should be relied upon to handle unicode.
+
+Transactions
+------------
+
+The psycopg2 dialect fully supports SAVEPOINT and two-phase commit operations.
+
+.. _psycopg2_isolation_level:
+
+Psycopg2 Transaction Isolation Level
+-------------------------------------
+
+As discussed in :ref:`postgresql_isolation_level`,
+all Postgresql dialects support setting of transaction isolation level
+both via the ``isolation_level`` parameter passed to :func:`.create_engine`,
+as well as the ``isolation_level`` argument used by
+:meth:`.Connection.execution_options`.  When using the psycopg2 dialect, these
+options make use of psycopg2's ``set_isolation_level()`` connection method,
+rather than emitting a Postgresql directive; this is because psycopg2's
+API-level setting is always emitted at the start of each transaction in any
+case.
+
+The psycopg2 dialect supports these constants for isolation level:
+
+* ``READ COMMITTED``
+* ``READ UNCOMMITTED``
+* ``REPEATABLE READ``
+* ``SERIALIZABLE``
+* ``AUTOCOMMIT``
+
+.. versionadded:: 0.8.2 support for AUTOCOMMIT isolation level when using
+   psycopg2.
+
+.. seealso::
+
+    :ref:`postgresql_isolation_level`
+
+    :ref:`pg8000_isolation_level`
+
+
+NOTICE logging
+---------------
+
+The psycopg2 dialect will log Postgresql NOTICE messages via the
+``sqlalchemy.dialects.postgresql`` logger::
+
+    import logging
+    logging.getLogger('sqlalchemy.dialects.postgresql').setLevel(logging.INFO)
+
+.. _psycopg2_hstore::
+
+HSTORE type
+------------
+
+The ``psycopg2`` DBAPI includes an extension to natively handle marshalling of
+the HSTORE type.   The SQLAlchemy psycopg2 dialect will enable this extension
+by default when it is detected that the target database has the HSTORE
+type set up for use.   In other words, when the dialect makes the first
+connection, a sequence like the following is performed:
+
+1. Request the available HSTORE oids using
+   ``psycopg2.extras.HstoreAdapter.get_oids()``.
+   If this function returns a list of HSTORE identifiers, we then determine
+   that the ``HSTORE`` extension is present.
+
+2. If the ``use_native_hstore`` flag is at its default of ``True``, and
+   we've detected that ``HSTORE`` oids are available, the
+   ``psycopg2.extensions.register_hstore()`` extension is invoked for all
+   connections.
+
+The ``register_hstore()`` extension has the effect of **all Python
+dictionaries being accepted as parameters regardless of the type of target
+column in SQL**. The dictionaries are converted by this extension into a
+textual HSTORE expression.  If this behavior is not desired, disable the
+use of the hstore extension by setting ``use_native_hstore`` to ``False`` as
+follows::
+
+    engine = create_engine("postgresql+psycopg2://scott:tiger@localhost/test",
+                use_native_hstore=False)
+
+The ``HSTORE`` type is **still supported** when the
+``psycopg2.extensions.register_hstore()`` extension is not used.  It merely
+means that the coercion between Python dictionaries and the HSTORE
+string format, on both the parameter side and the result side, will take
+place within SQLAlchemy's own marshalling logic, and not that of ``psycopg2``
+which may be more performant.

+.. dialect:: sqlite
+    :name: SQLite
+
+
+Date and Time Types
+-------------------
+
+SQLite does not have built-in DATE, TIME, or DATETIME types, and pysqlite does
+not provide out of the box functionality for translating values between Python
+`datetime` objects and a SQLite-supported format. SQLAlchemy's own
+:class:`~sqlalchemy.types.DateTime` and related types provide date formatting
+and parsing functionality when SQlite is used. The implementation classes are
+:class:`~.sqlite.DATETIME`, :class:`~.sqlite.DATE` and :class:`~.sqlite.TIME`.
+These types represent dates and times as ISO formatted strings, which also
+nicely support ordering. There's no reliance on typical "libc" internals for
+these functions so historical dates are fully supported.
+
+.. _sqlite_autoincrement:
+
+SQLite Auto Incrementing Behavior
+----------------------------------
+
+Background on SQLite's autoincrement is at: http://sqlite.org/autoinc.html
+
+Two things to note:
+
+* The AUTOINCREMENT keyword is **not** required for SQLite tables to
+  generate primary key values automatically. AUTOINCREMENT only means that the
+  algorithm used to generate ROWID values should be slightly different.
+* SQLite does **not** generate primary key (i.e. ROWID) values, even for
+  one column, if the table has a composite (i.e. multi-column) primary key.
+  This is regardless of the AUTOINCREMENT keyword being present or not.
+
+To specifically render the AUTOINCREMENT keyword on the primary key column
+when rendering DDL, add the flag ``sqlite_autoincrement=True`` to the Table
+construct::
+
+    Table('sometable', metadata,
+            Column('id', Integer, primary_key=True),
+            sqlite_autoincrement=True)
+
+Transaction Isolation Level
+---------------------------
+
+:func:`.create_engine` accepts an ``isolation_level`` parameter which results
+in the command ``PRAGMA read_uncommitted <level>`` being invoked for every new
+connection. Valid values for this parameter are ``SERIALIZABLE`` and ``READ
+UNCOMMITTED`` corresponding to a value of 0 and 1, respectively. See the
+section :ref:`pysqlite_serializable` for an important workaround when using
+serializable isolation with Pysqlite.
+
+Database Locking Behavior / Concurrency
+---------------------------------------
+
+Note that SQLite is not designed for a high level of concurrency. The database
+itself, being a file, is locked completely during write operations and within
+transactions, meaning exactly one connection has exclusive access to the
+database during this period - all other connections will be blocked during
+this time.
+
+The Python DBAPI specification also calls for a connection model that is
+always in a transaction; there is no BEGIN method, only commit and rollback.
+This implies that a SQLite DBAPI driver would technically allow only
+serialized access to a particular database file at all times. The pysqlite
+driver attempts to ameliorate this by deferring the actual BEGIN statement
+until the first DML (INSERT, UPDATE, or DELETE) is received within a
+transaction. While this breaks serializable isolation, it at least delays the
+exclusive locking inherent in SQLite's design.
+
+SQLAlchemy's default mode of usage with the ORM is known as
+"autocommit=False", which means the moment the :class:`.Session` begins to be
+used, a transaction is begun. As the :class:`.Session` is used, the autoflush
+feature, also on by default, will flush out pending changes to the database
+before each query. The effect of this is that a :class:`.Session` used in its
+default mode will often emit DML early on, long before the transaction is
+actually committed. This again will have the effect of serializing access to
+the SQLite database. If highly concurrent reads are desired against the SQLite
+database, it is advised that the autoflush feature be disabled, and
+potentially even that autocommit be re-enabled, which has the effect of each
+SQL statement and flush committing changes immediately.
+
+For more information on SQLite's lack of concurrency by design, please see
+`Situations Where Another RDBMS May Work Better - High Concurrency
+<http://www.sqlite.org/whentouse.html>`_ near the bottom of the page.
+
+.. _sqlite_foreign_keys:
+
+Foreign Key Support
+-------------------
+
+SQLite supports FOREIGN KEY syntax when emitting CREATE statements for tables,
+however by default these constraints have no effect on the operation of the
+table.
+
+Constraint checking on SQLite has three prerequisites:
+
+* At least version 3.6.19 of SQLite must be in use
+* The SQLite library must be compiled *without* the SQLITE_OMIT_FOREIGN_KEY
+  or SQLITE_OMIT_TRIGGER symbols enabled.
+* The ``PRAGMA foreign_keys = ON`` statement must be emitted on all
+  connections before use.
+
+SQLAlchemy allows for the ``PRAGMA`` statement to be emitted automatically for
+new connections through the usage of events::
+
+    from sqlalchemy.engine import Engine
+    from sqlalchemy import event
+
+    @event.listens_for(Engine, "connect")
+    def set_sqlite_pragma(dbapi_connection, connection_record):
+        cursor = dbapi_connection.cursor()
+        cursor.execute("PRAGMA foreign_keys=ON")
+        cursor.close()
+
+.. seealso::
+
+    `SQLite Foreign Key Support <http://www.sqlite.org/foreignkeys.html>`_
+    - on the SQLite web site.
+
+    :ref:`event_toplevel` - SQLAlchemy event API.
+
+.. _sqlite_type_reflection:
+
+Type Reflection
+---------------
+
+SQLite types are unlike those of most other database backends, in that
+the string name of the type usually does not correspond to a "type" in a
+one-to-one fashion.  Instead, SQLite links per-column typing behavior
+to one of five so-called "type affinities" based on a string matching
+pattern for the type.
+
+SQLAlchemy's reflection process, when inspecting types, uses a simple
+lookup table to link the keywords returned to provided SQLAlchemy types.
+This lookup table is present within the SQLite dialect as it is for all
+other dialects.  However, the SQLite dialect has a different "fallback"
+routine for when a particular type name is not located in the lookup map;
+it instead implements the SQLite "type affinity" scheme located at
+http://www.sqlite.org/datatype3.html section 2.1.
+
+The provided typemap will make direct associations from an exact string
+name match for the following types:
+
+:class:`~.types.BIGINT`, :class:`~.types.BLOB`,
+:class:`~.types.BOOLEAN`, :class:`~.types.BOOLEAN`,
+:class:`~.types.CHAR`, :class:`~.types.DATE`,
+:class:`~.types.DATETIME`, :class:`~.types.FLOAT`,
+:class:`~.types.DECIMAL`, :class:`~.types.FLOAT`,
+:class:`~.types.INTEGER`, :class:`~.types.INTEGER`,
+:class:`~.types.NUMERIC`, :class:`~.types.REAL`,
+:class:`~.types.SMALLINT`, :class:`~.types.TEXT`,
+:class:`~.types.TIME`, :class:`~.types.TIMESTAMP`,
+:class:`~.types.VARCHAR`, :class:`~.types.NVARCHAR`,
+:class:`~.types.NCHAR`
+
+When a type name does not match one of the above types, the "type affinity"
+lookup is used instead:
+
+* :class:`~.types.INTEGER` is returned if the type name includes the
+  string ``INT``
+* :class:`~.types.TEXT` is returned if the type name includes the
+  string ``CHAR``, ``CLOB`` or ``TEXT``
+* :class:`~.types.NullType` is returned if the type name includes the
+  string ``BLOB``
+* :class:`~.types.REAL` is returned if the type name includes the string
+  ``REAL``, ``FLOA`` or ``DOUB``.
+* Otherwise, the :class:`~.types.NUMERIC` type is used.
+
+.. versionadded:: 0.9.3 Support for SQLite type affinity rules when reflecting
+   columns.

+
+Driver
+------
+
+When using Python 2.5 and above, the built in ``sqlite3`` driver is
+already installed and no additional installation is needed.  Otherwise,
+the ``pysqlite2`` driver needs to be present.  This is the same driver as
+``sqlite3``, just with a different name.
+
+The ``pysqlite2`` driver will be loaded first, and if not found, ``sqlite3``
+is loaded.  This allows an explicitly installed pysqlite driver to take
+precedence over the built in one.   As with all dialects, a specific
+DBAPI module may be provided to :func:`~sqlalchemy.create_engine()` to control
+this explicitly::
+
+    from sqlite3 import dbapi2 as sqlite
+    e = create_engine('sqlite+pysqlite:///file.db', module=sqlite)
+
+
+Connect Strings
+---------------
+
+The file specification for the SQLite database is taken as the "database"
+portion of the URL.  Note that the format of a SQLAlchemy url is::
+
+    driver://user:pass@host/database

+This means that the actual filename to be used starts with the characters to
+the **right** of the third slash.   So connecting to a relative filepath
+looks like::
+
+    # relative path
+    e = create_engine('sqlite:///path/to/database.db')
+
+An absolute path, which is denoted by starting with a slash, means you
+need **four** slashes::
+
+    # absolute path
+    e = create_engine('sqlite:////path/to/database.db')
+
+To use a Windows path, regular drive specifications and backslashes can be
+used. Double backslashes are probably needed::
+
+    # absolute path on Windows
+    e = create_engine('sqlite:///C:\\\\path\\\\to\\\\database.db')
+
+The sqlite ``:memory:`` identifier is the default if no filepath is
+present.  Specify ``sqlite://`` and nothing else::
+
+    # in-memory database
+    e = create_engine('sqlite://')
+
+Compatibility with sqlite3 "native" date and datetime types
+-----------------------------------------------------------
+
+The pysqlite driver includes the sqlite3.PARSE_DECLTYPES and
+sqlite3.PARSE_COLNAMES options, which have the effect of any column
+or expression explicitly cast as "date" or "timestamp" will be converted
+to a Python date or datetime object.  The date and datetime types provided
+with the pysqlite dialect are not currently compatible with these options,
+since they render the ISO date/datetime including microseconds, which
+pysqlite's driver does not.   Additionally, SQLAlchemy does not at
+this time automatically render the "cast" syntax required for the
+freestanding functions "current_timestamp" and "current_date" to return
+datetime/date types natively.   Unfortunately, pysqlite
+does not provide the standard DBAPI types in ``cursor.description``,
+leaving SQLAlchemy with no way to detect these types on the fly
+without expensive per-row type checks.
+
+Keeping in mind that pysqlite's parsing option is not recommended,
+nor should be necessary, for use with SQLAlchemy, usage of PARSE_DECLTYPES
+can be forced if one configures "native_datetime=True" on create_engine()::
+
+    engine = create_engine('sqlite://',
+        connect_args={'detect_types':
+            sqlite3.PARSE_DECLTYPES|sqlite3.PARSE_COLNAMES},
+        native_datetime=True
+    )
+
+With this flag enabled, the DATE and TIMESTAMP types (but note - not the
+DATETIME or TIME types...confused yet ?) will not perform any bind parameter
+or result processing. Execution of "func.current_date()" will return a string.
+"func.current_timestamp()" is registered as returning a DATETIME type in
+SQLAlchemy, so this function still receives SQLAlchemy-level result
+processing.
+
+.. _pysqlite_threading_pooling:
+
+Threading/Pooling Behavior
+---------------------------
+
+Pysqlite's default behavior is to prohibit the usage of a single connection
+in more than one thread.   This is originally intended to work with older
+versions of SQLite that did not support multithreaded operation under
+various circumstances.  In particular, older SQLite versions
+did not allow a ``:memory:`` database to be used in multiple threads
+under any circumstances.
+
+Pysqlite does include a now-undocumented flag known as
+``check_same_thread`` which will disable this check, however note that
+pysqlite connections are still not safe to use in concurrently in multiple
+threads.  In particular, any statement execution calls would need to be
+externally mutexed, as Pysqlite does not provide for thread-safe propagation
+of error messages among other things.   So while even ``:memory:`` databases
+can be shared among threads in modern SQLite, Pysqlite doesn't provide enough
+thread-safety to make this usage worth it.
+
+SQLAlchemy sets up pooling to work with Pysqlite's default behavior:
+
+* When a ``:memory:`` SQLite database is specified, the dialect by default
+  will use :class:`.SingletonThreadPool`. This pool maintains a single
+  connection per thread, so that all access to the engine within the current
+  thread use the same ``:memory:`` database - other threads would access a
+  different ``:memory:`` database.
+* When a file-based database is specified, the dialect will use
+  :class:`.NullPool` as the source of connections. This pool closes and
+  discards connections which are returned to the pool immediately. SQLite
+  file-based connections have extremely low overhead, so pooling is not
+  necessary. The scheme also prevents a connection from being used again in
+  a different thread and works best with SQLite's coarse-grained file locking.
+
+  .. versionchanged:: 0.7
+      Default selection of :class:`.NullPool` for SQLite file-based databases.
+      Previous versions select :class:`.SingletonThreadPool` by
+      default for all SQLite databases.
+
+
+Using a Memory Database in Multiple Threads
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To use a ``:memory:`` database in a multithreaded scenario, the same
+connection object must be shared among threads, since the database exists
+only within the scope of that connection.   The
+:class:`.StaticPool` implementation will maintain a single connection
+globally, and the ``check_same_thread`` flag can be passed to Pysqlite
+as ``False``::
+
+    from sqlalchemy.pool import StaticPool
+    engine = create_engine('sqlite://',
+                        connect_args={'check_same_thread':False},
+                        poolclass=StaticPool)
+
+Note that using a ``:memory:`` database in multiple threads requires a recent
+version of SQLite.
+
+Using Temporary Tables with SQLite
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Due to the way SQLite deals with temporary tables, if you wish to use a
+temporary table in a file-based SQLite database across multiple checkouts
+from the connection pool, such as when using an ORM :class:`.Session` where
+the temporary table should continue to remain after :meth:`.Session.commit` or
+:meth:`.Session.rollback` is called, a pool which maintains a single
+connection must be used.   Use :class:`.SingletonThreadPool` if the scope is
+only needed within the current thread, or :class:`.StaticPool` is scope is
+needed within multiple threads for this case::
+
+    # maintain the same connection per thread
+    from sqlalchemy.pool import SingletonThreadPool
+    engine = create_engine('sqlite:///mydb.db',
+                        poolclass=SingletonThreadPool)
+
+
+    # maintain the same connection across all threads
+    from sqlalchemy.pool import StaticPool
+    engine = create_engine('sqlite:///mydb.db',
+                        poolclass=StaticPool)
+
+Note that :class:`.SingletonThreadPool` should be configured for the number
+of threads that are to be used; beyond that number, connections will be
+closed out in a non deterministic way.
+
+Unicode
+-------
+
+The pysqlite driver only returns Python ``unicode`` objects in result sets,
+never plain strings, and accommodates ``unicode`` objects within bound
+parameter values in all cases.   Regardless of the SQLAlchemy string type in
+use, string-based result values will by Python ``unicode`` in Python 2.
+The :class:`.Unicode` type should still be used to indicate those columns that
+require unicode, however, so that non-``unicode`` values passed inadvertently
+will emit a warning.  Pysqlite will emit an error if a non-``unicode`` string
+is passed containing non-ASCII characters.
+
+.. _pysqlite_serializable:
+
+Serializable Transaction Isolation
+----------------------------------
+
+The pysqlite DBAPI driver has a long-standing bug in which transactional
+state is not begun until the first DML statement, that is INSERT, UPDATE
+or DELETE, is emitted.  A SELECT statement will not cause transactional
+state to begin.   While this mode of usage is fine for typical situations
+and has the advantage that the SQLite database file is not prematurely
+locked, it breaks serializable transaction isolation, which requires
+that the database file be locked upon any SQL being emitted.
+
+To work around this issue, the ``BEGIN`` keyword can be emitted
+at the start of each transaction.   The following recipe establishes
+a :meth:`.ConnectionEvents.begin` handler to achieve this::
+
+    from sqlalchemy import create_engine, event
+
+    engine = create_engine("sqlite:///myfile.db",
+                           isolation_level='SERIALIZABLE')
+
+    @event.listens_for(engine, "begin")
+    def do_begin(conn):
+        conn.execute("BEGIN")

+"""SQL connections, SQL execution and high-level DB-API interface.
+
+The engine package defines the basic components used to interface
+DB-API modules with higher-level statement construction,
+connection-management, execution and result contexts.  The primary
+"entry point" class into this package is the Engine and its public
+constructor ``create_engine()``.
+
+This package includes:
+
+base.py
+    Defines interface classes and some implementation classes which
+    comprise the basic components used to interface between a DB-API,
+    constructed and plain-text statements, connections, transactions,
+    and results.
+
+default.py
+    Contains default implementations of some of the components defined
+    in base.py.  All current database dialects use the classes in
+    default.py as base classes for their own database-specific
+    implementations.
+
+strategies.py
+    The mechanics of constructing ``Engine`` objects are represented
+    here.  Defines the ``EngineStrategy`` class which represents how
+    to go from arguments specified to the ``create_engine()``
+    function, to a fully constructed ``Engine``, including
+    initialization of connection pooling, dialects, and specific
+    subclasses of ``Engine``.
+
+threadlocal.py
+    The ``TLEngine`` class is defined here, which is a subclass of
+    the generic ``Engine`` and tracks ``Connection`` and
+    ``Transaction`` objects against the identity of the current
+    thread.  This allows certain programming patterns based around
+    the concept of a "thread-local connection" to be possible.
+    The ``TLEngine`` is created by using the "threadlocal" engine
+    strategy in conjunction with the ``create_engine()`` function.
+
+url.py
+    Defines the ``URL`` class which represents the individual
+    components of a string URL passed to ``create_engine()``.  Also
+    defines a basic module-loading strategy for the dialect specifier
+    within a URL.

+    first positional argument, usually a string
+    that indicates database dialect and connection arguments::
+
+
+        engine = create_engine("postgresql://scott:tiger@localhost/test")
+
+    Additional keyword arguments may then follow it which
+    establish various options on the resulting :class:`.Engine`
+    and its underlying :class:`.Dialect` and :class:`.Pool`
+    constructs::
+
+        engine = create_engine("mysql://scott:tiger@hostname/dbname",
+                                    encoding='latin1', echo=True)
+
+    The string form of the URL is
+    ``dialect[+driver]://user:password@host/dbname[?key=value..]``, where
+    ``dialect`` is a database name such as ``mysql``, ``oracle``,
+    ``postgresql``, etc., and ``driver`` the name of a DBAPI, such as
+    ``psycopg2``, ``pyodbc``, ``cx_oracle``, etc.  Alternatively,
+    the URL can be an instance of :class:`~sqlalchemy.engine.url.URL`.
+
+    ``**kwargs`` takes a wide variety of options which are routed
+    towards their appropriate components.  Arguments may be specific to
+    the :class:`.Engine`, the underlying :class:`.Dialect`, as well as the
+    :class:`.Pool`.  Specific dialects also accept keyword arguments that
+    are unique to that dialect.   Here, we describe the parameters
+    that are common to most :func:`.create_engine()` usage.
+
+    Once established, the newly resulting :class:`.Engine` will
+    request a connection from the underlying :class:`.Pool` once
+    :meth:`.Engine.connect` is called, or a method which depends on it
+    such as :meth:`.Engine.execute` is invoked.   The :class:`.Pool` in turn
+    will establish the first actual DBAPI connection when this request
+    is received.   The :func:`.create_engine` call itself does **not**
+    establish any actual DBAPI connections directly.
+

+
+        :doc:`/dialects/index`
+
+        :ref:`connections_toplevel`
+
+    :param case_sensitive=True: if False, result column names
+       will match in a case-insensitive fashion, that is,
+       ``row['SomeColumn']``.
+
+       .. versionchanged:: 0.8
+           By default, result row names match case-sensitively.
+           In version 0.7 and prior, all matches were case-insensitive.
+
+    :param connect_args: a dictionary of options which will be
+        passed directly to the DBAPI's ``connect()`` method as
+        additional keyword arguments.  See the example
+        at :ref:`custom_dbapi_args`.
+
+    :param convert_unicode=False: if set to True, sets
+        the default behavior of ``convert_unicode`` on the
+        :class:`.String` type to ``True``, regardless
+        of a setting of ``False`` on an individual
+        :class:`.String` type, thus causing all :class:`.String`
+        -based columns
+        to accommodate Python ``unicode`` objects.  This flag
+        is useful as an engine-wide setting when using a
+        DBAPI that does not natively support Python
+        ``unicode`` objects and raises an error when
+        one is received (such as pyodbc with FreeTDS).
+
+        See :class:`.String` for further details on
+        what this flag indicates.
+
+    :param creator: a callable which returns a DBAPI connection.
+        This creation function will be passed to the underlying
+        connection pool and will be used to create all new database
+        connections. Usage of this function causes connection
+        parameters specified in the URL argument to be bypassed.
+
+    :param echo=False: if True, the Engine will log all statements
+        as well as a repr() of their parameter lists to the engines
+        logger, which defaults to sys.stdout. The ``echo`` attribute of
+        ``Engine`` can be modified at any time to turn logging on and
+        off. If set to the string ``"debug"``, result rows will be
+        printed to the standard output as well. This flag ultimately
+        controls a Python logger; see :ref:`dbengine_logging` for
+        information on how to configure logging directly.
+
+    :param echo_pool=False: if True, the connection pool will log
+        all checkouts/checkins to the logging stream, which defaults to
+        sys.stdout. This flag ultimately controls a Python logger; see
+        :ref:`dbengine_logging` for information on how to configure logging
+        directly.
+
+    :param encoding: Defaults to ``utf-8``.  This is the string
+        encoding used by SQLAlchemy for string encode/decode
+        operations which occur within SQLAlchemy, **outside of
+        the DBAPI.**  Most modern DBAPIs feature some degree of
+        direct support for Python ``unicode`` objects,
+        what you see in Python 2 as a string of the form
+        ``u'some string'``.  For those scenarios where the
+        DBAPI is detected as not supporting a Python ``unicode``
+        object, this encoding is used to determine the
+        source/destination encoding.  It is **not used**
+        for those cases where the DBAPI handles unicode
+        directly.
+
+        To properly configure a system to accommodate Python
+        ``unicode`` objects, the DBAPI should be
+        configured to handle unicode to the greatest
+        degree as is appropriate - see
+        the notes on unicode pertaining to the specific
+        target database in use at :ref:`dialect_toplevel`.
+
+        Areas where string encoding may need to be accommodated
+        outside of the DBAPI include zero or more of:
+
+        * the values passed to bound parameters, corresponding to
+          the :class:`.Unicode` type or the :class:`.String` type
+          when ``convert_unicode`` is ``True``;
+        * the values returned in result set columns corresponding
+          to the :class:`.Unicode` type or the :class:`.String`
+          type when ``convert_unicode`` is ``True``;
+        * the string SQL statement passed to the DBAPI's
+          ``cursor.execute()`` method;
+        * the string names of the keys in the bound parameter
+          dictionary passed to the DBAPI's ``cursor.execute()``
+          as well as ``cursor.setinputsizes()`` methods;
+        * the string column names retrieved from the DBAPI's
+          ``cursor.description`` attribute.
+
+        When using Python 3, the DBAPI is required to support
+        *all* of the above values as Python ``unicode`` objects,
+        which in Python 3 are just known as ``str``.  In Python 2,
+        the DBAPI does not specify unicode behavior at all,
+        so SQLAlchemy must make decisions for each of the above
+        values on a per-DBAPI basis - implementations are
+        completely inconsistent in their behavior.
+
+    :param execution_options: Dictionary execution options which will
+        be applied to all connections.  See
+        :meth:`~sqlalchemy.engine.Connection.execution_options`
+
+    :param implicit_returning=True: When ``True``, a RETURNING-
+        compatible construct, if available, will be used to
+        fetch newly generated primary key values when a single row
+        INSERT statement is emitted with no existing returning()
+        clause.  This applies to those backends which support RETURNING
+        or a compatible construct, including Postgresql, Firebird, Oracle,
+        Microsoft SQL Server.   Set this to ``False`` to disable
+        the automatic usage of RETURNING.
+
+    :param label_length=None: optional integer value which limits
+        the size of dynamically generated column labels to that many
+        characters. If less than 6, labels are generated as
+        "_(counter)". If ``None``, the value of
+        ``dialect.max_identifier_length`` is used instead.
+
+    :param listeners: A list of one or more
+        :class:`~sqlalchemy.interfaces.PoolListener` objects which will
+        receive connection pool events.
+
+    :param logging_name:  String identifier which will be used within
+        the "name" field of logging records generated within the
+        "sqlalchemy.engine" logger. Defaults to a hexstring of the
+        object's id.
+
+    :param max_overflow=10: the number of connections to allow in
+        connection pool "overflow", that is connections that can be
+        opened above and beyond the pool_size setting, which defaults
+        to five. this is only used with :class:`~sqlalchemy.pool.QueuePool`.
+
+    :param module=None: reference to a Python module object (the module
+        itself, not its string name).  Specifies an alternate DBAPI module to
+        be used by the engine's dialect.  Each sub-dialect references a
+        specific DBAPI which will be imported before first connect.  This
+        parameter causes the import to be bypassed, and the given module to
+        be used instead. Can be used for testing of DBAPIs as well as to
+        inject "mock" DBAPI implementations into the :class:`.Engine`.
+
+    :param pool=None: an already-constructed instance of
+        :class:`~sqlalchemy.pool.Pool`, such as a
+        :class:`~sqlalchemy.pool.QueuePool` instance. If non-None, this
+        pool will be used directly as the underlying connection pool
+        for the engine, bypassing whatever connection parameters are
+        present in the URL argument. For information on constructing
+        connection pools manually, see :ref:`pooling_toplevel`.
+
+    :param poolclass=None: a :class:`~sqlalchemy.pool.Pool`
+        subclass, which will be used to create a connection pool
+        instance using the connection parameters given in the URL. Note
+        this differs from ``pool`` in that you don't actually
+        instantiate the pool in this case, you just indicate what type
+        of pool to be used.
+
+    :param pool_logging_name:  String identifier which will be used within
+       the "name" field of logging records generated within the
+       "sqlalchemy.pool" logger. Defaults to a hexstring of the object's
+       id.
+
+    :param pool_size=5: the number of connections to keep open
+        inside the connection pool. This used with
+        :class:`~sqlalchemy.pool.QueuePool` as
+        well as :class:`~sqlalchemy.pool.SingletonThreadPool`.  With
+        :class:`~sqlalchemy.pool.QueuePool`, a ``pool_size`` setting
+        of 0 indicates no limit; to disable pooling, set ``poolclass`` to
+        :class:`~sqlalchemy.pool.NullPool` instead.
+
+    :param pool_recycle=-1: this setting causes the pool to recycle
+        connections after the given number of seconds has passed. It
+        defaults to -1, or no timeout. For example, setting to 3600
+        means connections will be recycled after one hour. Note that
+        MySQL in particular will disconnect automatically if no
+        activity is detected on a connection for eight hours (although
+        this is configurable with the MySQLDB connection itself and the
+        server configuration as well).
+
+    :param pool_reset_on_return='rollback': set the "reset on return"
+        behavior of the pool, which is whether ``rollback()``,
+        ``commit()``, or nothing is called upon connections
+        being returned to the pool.  See the docstring for
+        ``reset_on_return`` at :class:`.Pool`.
+
+        .. versionadded:: 0.7.6
+
+    :param pool_timeout=30: number of seconds to wait before giving
+        up on getting a connection from the pool. This is only used
+        with :class:`~sqlalchemy.pool.QueuePool`.
+
+    :param strategy='plain': selects alternate engine implementations.
+        Currently available are:
+
+        * the ``threadlocal`` strategy, which is described in
+          :ref:`threadlocal_strategy`;
+        * the ``mock`` strategy, which dispatches all statement
+          execution to a function passed as the argument ``executor``.
+          See `example in the FAQ
+          <http://www.sqlalchemy.org/trac/wiki/FAQ#HowcanIgettheCREATETABLEDROPTABLEoutputasastring>`_.
+
+    :param executor=None: a function taking arguments

+          when executed in 'autocommit' mode, i.e. when an explicit
+          transaction is not begun on the connection. Note that DBAPI
+          connections by default are always in a transaction - SQLAlchemy uses
+          rules applied to different kinds of statements to determine if
+          COMMIT will be invoked in order to provide its "autocommit" feature.
+          Typically, all INSERT/UPDATE/DELETE statements as well as
+          CREATE/DROP statements have autocommit behavior enabled; SELECT
+          constructs do not. Use this option when invoking a SELECT or other
+          specific SQL construct where COMMIT is desired (typically when
+          calling stored procedures and such), and an explicit
+          transaction is not in progress.
+
+        :param compiled_cache: Available on: Connection.
+          A dictionary where :class:`.Compiled` objects
+          will be cached when the :class:`.Connection` compiles a clause
+          expression into a :class:`.Compiled` object.
+          It is the user's responsibility to
+          manage the size of this dictionary, which will have keys
+          corresponding to the dialect, clause element, the column
+          names within the VALUES or SET clause of an INSERT or UPDATE,
+          as well as the "batch" mode for an INSERT or UPDATE statement.
+          The format of this dictionary is not guaranteed to stay the
+          same in future releases.
+
+          Note that the ORM makes use of its own "compiled" caches for
+          some operations, including flush operations.  The caching
+          used by the ORM internally supersedes a cache dictionary
+          specified here.
+
+        :param isolation_level: Available on: Connection.
+          Set the transaction isolation level for
+          the lifespan of this connection.   Valid values include
+          those string values accepted by the ``isolation_level``
+          parameter passed to :func:`.create_engine`, and are
+          database specific, including those for :ref:`sqlite_toplevel`,
+          :ref:`postgresql_toplevel` - see those dialect's documentation
+          for further info.
+
+          Note that this option necessarily affects the underlying
+          DBAPI connection for the lifespan of the originating
+          :class:`.Connection`, and is not per-execution. This
+          setting is not removed until the underlying DBAPI connection
+          is returned to the connection pool, i.e.
+          the :meth:`.Connection.close` method is called.
+
+        :param no_parameters: When ``True``, if the final parameter
+          list or dictionary is totally empty, will invoke the

+         * a :class:`.Compiled` object
+
+        :param \*multiparams/\**params: represent bound parameter
+         values to be used in the execution.   Typically,
+         the format is either a collection of one or more
+         dictionaries passed to \*multiparams::
+
+             conn.execute(
+                 table.insert(),
+                 {"id":1, "value":"v1"},
+                 {"id":2, "value":"v2"}
+             )
+
+         ...or individual key/values interpreted by \**params::
+
+             conn.execute(
+                 table.insert(), id=1, value="v1"
+             )
+
+         In the case that a plain SQL string is passed, and the underlying
+         DBAPI accepts positional bind parameters, a collection of tuples
+         or individual values in \*multiparams may be passed::
+
+             conn.execute(
+                 "INSERT INTO table (id, value) VALUES (?, ?)",
+                 (1, "v1"), (2, "v2")
+             )
+
+             conn.execute(
+                 "INSERT INTO table (id, value) VALUES (?, ?)",
+                 1, "v1"
+             )
+
+         Note above, the usage of a question mark "?" or other
+         symbol is contingent upon the "paramstyle" accepted by the DBAPI
+         in use, which may be any of "qmark", "named", "pyformat", "format",
+         "numeric".   See `pep-249 <http://www.python.org/dev/peps/pep-0249/>`_
+         for details on paramstyle.
+
+         To execute a textual SQL statement which uses bound parameters in a
+         DBAPI-agnostic way, use the :func:`~.expression.text` construct.

+    """Define the behavior of a specific database and DB-API combination.
+
+    Any aspect of metadata definition, SQL query generation,
+    execution, result-set handling, or anything else which varies
+    between databases is defined under the general category of the
+    Dialect.  The Dialect acts as a factory for other
+    database-specific object implementations including
+    ExecutionContext, Compiled, DefaultGenerator, and TypeEngine.
+
+    All Dialects implement the following attributes:
+
+    name
+      identifying name for the dialect from a DBAPI-neutral point of view
+      (i.e. 'sqlite')
+
+    driver
+      identifying name for the dialect's DBAPI
+
+    positional
+      True if the paramstyle for this Dialect is positional.
+
+    paramstyle
+      the paramstyle to be used (some DB-APIs support multiple
+      paramstyles).
+
+    convert_unicode
+      True if Unicode conversion should be applied to all ``str``
+      types.
+
+    encoding
+      type of encoding to use for unicode, usually defaults to
+      'utf-8'.
+
+    statement_compiler
+      a :class:`.Compiled` class used to compile SQL statements
+
+    ddl_compiler
+      a :class:`.Compiled` class used to compile DDL statements
+
+    server_version_info
+      a tuple containing a version number for the DB backend in use.
+      This value is only available for supporting dialects, and is
+      typically populated during the initial connection to the database.
+
+    default_schema_name
+     the name of the default schema.  This value is only available for
+     supporting dialects, and is typically populated during the
+     initial connection to the database.
+
+    execution_ctx_cls
+      a :class:`.ExecutionContext` class used to handle statement execution
+
+    execute_sequence_format
+      either the 'tuple' or 'list' type, depending on what cursor.execute()
+      accepts for the second argument (they vary).
+
+    preparer
+      a :class:`~sqlalchemy.sql.compiler.IdentifierPreparer` class used to
+      quote identifiers.
+
+    supports_alter
+      ``True`` if the database supports ``ALTER TABLE``.
+
+    max_identifier_length
+      The maximum length of identifier names.
+
+    supports_unicode_statements
+      Indicate whether the DB-API can receive SQL statements as Python
+      unicode strings
+
+    supports_unicode_binds
+      Indicate whether the DB-API can receive string bind parameters
+      as Python unicode strings
+
+    supports_sane_rowcount
+      Indicate whether the dialect properly implements rowcount for
+      ``UPDATE`` and ``DELETE`` statements.
+
+    supports_sane_multi_rowcount
+      Indicate whether the dialect properly implements rowcount for
+      ``UPDATE`` and ``DELETE`` statements when executed via
+      executemany.
+
+    preexecute_autoincrement_sequences
+      True if 'implicit' primary key functions must be executed separately
+      in order to get their value.   This is currently oriented towards
+      Postgresql.
+
+    implicit_returning
+      use RETURNING or equivalent during INSERT execution in order to load
+      newly generated primary keys and other column defaults in one execution,
+      which are then available via inserted_primary_key.
+      If an insert statement has returning() specified explicitly,
+      the "implicit" functionality is not used and inserted_primary_key
+      will not be available.
+
+    dbapi_type_map
+      A mapping of DB-API type objects present in this Dialect's
+      DB-API implementation mapped to TypeEngine implementations used
+      by the dialect.
+
+      This is used to apply types to result sets based on the DB-API
+      types present in cursor.description; it only takes effect for
+      result sets against textual statements where no explicit
+      typemap was present.
+
+    colspecs
+      A dictionary of TypeEngine classes from sqlalchemy.types mapped
+      to subclasses that are specific to the dialect class.  This
+      dictionary is class-level only and is not accessed from the
+      dialect instance itself.
+
+    supports_default_values
+      Indicates if the construct ``INSERT INTO tablename DEFAULT
+      VALUES`` is supported
+
+    supports_sequences
+      Indicates if the dialect supports CREATE SEQUENCE or similar.
+
+    sequences_optional
+      If True, indicates if the "optional" flag on the Sequence() construct
+      should signal to not generate a CREATE SEQUENCE. Applies only to
+      dialects that support sequences. Currently used only to allow Postgresql
+      SERIAL to be used on a column that specifies Sequence() for usage on
+      other backends.
+

+"""Provides an abstraction for obtaining database schema information.
+
+Usage Notes:
+
+Here are some general conventions when accessing the low level inspector
+methods such as get_table_names, get_columns, etc.
+
+1. Inspector methods return lists of dicts in most cases for the following
+   reasons:
+
+   * They're both standard types that can be serialized.
+   * Using a dict instead of a tuple allows easy expansion of attributes.
+   * Using a list for the outer structure maintains order and is easy to work
+     with (e.g. list comprehension [d['name'] for d in cols]).
+
+2. Records that contain a name, such as the column name in a column record
+   use the key 'name'. So for most return values, each record will have a
+   'name' attribute..

+"""Attribute implementation for _Dispatch classes.
+
+The various listener targets for a particular event class are represented
+as attributes, which refer to collections of listeners to be fired off.
+These collections can exist at the class level as well as at the instance
+level.  An event is fired off using code like this::
+
+    some_object.dispatch.first_connect(arg1, arg2)
+
+Above, ``some_object.dispatch`` would be an instance of ``_Dispatch`` and
+``first_connect`` is typically an instance of ``_ListenerCollection``
+if event listeners are present, or ``_EmptyListener`` if none are present.
+
+The attribute mechanics here spend effort trying to ensure listener functions
+are available with a minimum of function call overhead, that unnecessary
+objects aren't created (i.e. many empty per-instance listener collections),
+as well as that everything is garbage collectable when owning references are
+lost.  Other features such as "propagation" of listener functions across
+many ``_Dispatch`` instances, "joining" of multiple ``_Dispatch`` instances,
+as well as support for subclass propagation (e.g. events assigned to
+``Pool`` vs. ``QueuePool``) are all implemented here.

+    subclasses, including :class:`.MetaData`, :class:`.Table`,
+    :class:`.Column`.
+
+    :class:`.MetaData` and :class:`.Table` support events
+    specifically regarding when CREATE and DROP
+    DDL is emitted to the database.
+
+    Attachment events are also provided to customize
+    behavior whenever a child schema element is associated
+    with a parent, such as, when a :class:`.Column` is associated
+    with its :class:`.Table`, when a :class:`.ForeignKeyConstraint`
+    is associated with a :class:`.Table`, etc.

+
+        event.listen(some_table, "after_create", after_create)

+    of DDL clause constructs, which are themselves appropriate

+
+        Alternatively, a "chained" style of event handling can be
+        used, by configuring the handler with the ``retval=True``
+        modifier and returning the new exception instance from the
+        function.  In this case, event handling will continue onto the

+
+        Handlers that return ``None`` may remain within this chain; the
+        last non-``None`` return value is the one that continues to be

+    attribute which references an attribute on members of the
+    target.
+
+    The returned value is an instance of :class:`.AssociationProxy`.
+
+    Implements a Python property representing a relationship as a collection
+    of simpler values, or a scalar value.  The proxied property will mimic
+    the collection type of the target (list, dict or set), or, in the case of
+    a one to one relationship, a simple scalar value.
+
+    :param target_collection: Name of the attribute we'll proxy to.
+      This attribute is typically mapped by
+      :func:`~sqlalchemy.orm.relationship` to link to a target collection, but
+      can also be a many-to-one or non-scalar relationship.
+
+    :param attr: Attribute on the associated instance or instances we'll
+      proxy for.
+
+      For example, given a target collection of [obj1, obj2], a list created
+      by this proxy property would look like [getattr(obj1, *attr*),
+      getattr(obj2, *attr*)]
+
+      If the relationship is one-to-one or otherwise uselist=False, then
+      simply: getattr(obj, *attr*)

+
+      When new items are added to this proxied collection, new instances of
+      the class collected by the target collection will be created.  For list
+      and set collections, the target class constructor will be called with
+      the 'value' for the new instance.  For dict types, two arguments are
+      passed: key and value.
+
+      If you want to construct instances differently, supply a *creator*
+      function that takes arguments as above and returns instances.
+
+      For scalar relationships, creator() will be called if the target is None.
+      If the target is present, set operations are proxied to setattr() on the
+      associated object.
+
+      If you have an associated object with multiple attributes, you may set
+      up multiple association proxies mapping to different attributes.  See
+      the unit tests for examples, and for examples of how creator() functions
+      can be used to construct the scalar relationship on-demand in this
+      situation.

+"""Define an extension to the :mod:`sqlalchemy.ext.declarative` system
+which automatically generates mapped classes and relationships from a database
+schema, typically though not necessarily one which is reflected.
+
+.. versionadded:: 0.9.1 Added :mod:`sqlalchemy.ext.automap`.
+
+.. note::
+
+    The :mod:`sqlalchemy.ext.automap` extension should be considered
+    **experimental** as of 0.9.1.   Featureset and API stability is
+    not guaranteed at this time.
+
+It is hoped that the :class:`.AutomapBase` system provides a quick
+and modernized solution to the problem that the very famous
+`SQLSoup <https://sqlsoup.readthedocs.org/en/latest/>`_
+also tries to solve, that of generating a quick and rudimentary object
+model from an existing database on the fly.  By addressing the issue strictly
+at the mapper configuration level, and integrating fully with existing
+Declarative class techniques, :class:`.AutomapBase` seeks to provide
+a well-integrated approach to the issue of expediently auto-generating ad-hoc
+mappings.
+
+
+Basic Use
+=========
+
+The simplest usage is to reflect an existing database into a new model.
+We create a new :class:`.AutomapBase` class in a similar manner as to how
+we create a declarative base class, using :func:`.automap_base`.
+We then call :meth:`.AutomapBase.prepare` on the resulting base class,
+asking it to reflect the schema and produce mappings::
+
+    from sqlalchemy.ext.automap import automap_base
+    from sqlalchemy.orm import Session
+    from sqlalchemy import create_engine
+
+    Base = automap_base()
+
+    # engine, suppose it has two tables 'user' and 'address' set up
+    engine = create_engine("sqlite:///mydatabase.db")
+
+    # reflect the tables
+    Base.prepare(engine, reflect=True)
+
+    # mapped classes are now created with names by default
+    # matching that of the table name.
+    User = Base.classes.user
+    Address = Base.classes.address
+
+    session = Session(engine)
+
+    # rudimentary relationships are produced
+    session.add(Address(email_address="foo@bar.com", user=User(name="foo")))
+    session.commit()
+
+    # collection-based relationships are by default named
+    # "<classname>_collection"
+    print (u1.address_collection)
+
+Above, calling :meth:`.AutomapBase.prepare` while passing along the
+:paramref:`.AutomapBase.prepare.reflect` parameter indicates that the
+:meth:`.MetaData.reflect` method will be called on this declarative base
+classes' :class:`.MetaData` collection; then, each viable
+:class:`.Table` within the :class:`.MetaData` will get a new mapped class
+generated automatically.  The :class:`.ForeignKeyConstraint` objects which
+link the various tables together will be used to produce new, bidirectional
+:func:`.relationship` objects between classes.   The classes and relationships
+follow along a default naming scheme that we can customize.  At this point,
+our basic mapping consisting of related ``User`` and ``Address`` classes is
+ready to use in the traditional way.
+
+Generating Mappings from an Existing MetaData
+=============================================
+
+We can pass a pre-declared :class:`.MetaData` object to :func:`.automap_base`.
+This object can be constructed in any way, including programmatically, from
+a serialized file, or from itself being reflected using
+:meth:`.MetaData.reflect`.  Below we illustrate a combination of reflection and
+explicit table declaration::
+
+    from sqlalchemy import create_engine, MetaData, Table, Column, ForeignKey
+    engine = create_engine("sqlite:///mydatabase.db")
+
+    # produce our own MetaData object
+    metadata = MetaData()
+
+    # we can reflect it ourselves from a database, using options
+    # such as 'only' to limit what tables we look at...
+    metadata.reflect(engine, only=['user', 'address'])
+
+    # ... or just define our own Table objects with it (or combine both)
+    Table('user_order', metadata,
+                    Column('id', Integer, primary_key=True),
+                    Column('user_id', ForeignKey('user.id'))
+                )
+
+    # we can then produce a set of mappings from this MetaData.
+    Base = automap_base(metadata=metadata)
+
+    # calling prepare() just sets up mapped classes and relationships.
+    Base.prepare()
+
+    # mapped classes are ready
+    User, Address, Order = Base.classes.user, Base.classes.address,\
+        Base.classes.user_order
+
+Specifying Classes Explcitly
+============================
+
+The :mod:`.sqlalchemy.ext.automap` extension allows classes to be defined
+explicitly, in a way similar to that of the :class:`.DeferredReflection` class.
+Classes that extend from :class:`.AutomapBase` act like regular declarative
+classes, but are not immediately mapped after their construction, and are
+instead mapped when we call :meth:`.AutomapBase.prepare`.  The
+:meth:`.AutomapBase.prepare` method will make use of the classes we've
+established based on the table name we use.  If our schema contains tables
+``user`` and ``address``, we can define one or both of the classes to be used::
+
+    from sqlalchemy.ext.automap import automap_base
+    from sqlalchemy import create_engine
+
+    # automap base
+    Base = automap_base()
+
+    # pre-declare User for the 'user' table
+    class User(Base):
+        __tablename__ = 'user'
+
+        # override schema elements like Columns
+        user_name = Column('name', String)
+
+        # override relationships too, if desired.
+        # we must use the same name that automap would use for the
+        # relationship, and also must refer to the class name that automap will
+        # generate for "address"
+        address_collection = relationship("address", collection_class=set)
+
+    # reflect
+    engine = create_engine("sqlite:///mydatabase.db")
+    Base.prepare(engine, reflect=True)
+
+    # we still have Address generated from the tablename "address",
+    # but User is the same as Base.classes.User now
+
+    Address = Base.classes.address
+
+    u1 = session.query(User).first()
+    print (u1.address_collection)
+
+    # the backref is still there:
+    a1 = session.query(Address).first()
+    print (a1.user)
+
+Above, one of the more intricate details is that we illustrated overriding
+one of the :func:`.relationship` objects that automap would have created.
+To do this, we needed to make sure the names match up with what automap
+would normally generate, in that the relationship name would be
+``User.address_collection`` and the name of the class referred to, from
+automap's perspective, is called ``address``, even though we are referring to
+it as ``Address`` within our usage of this class.
+
+Overriding Naming Schemes
+=========================
+
+:mod:`.sqlalchemy.ext.automap` is tasked with producing mapped classes and
+relationship names based on a schema, which means it has decision points in how
+these names are determined.  These three decision points are provided using
+functions which can be passed to the :meth:`.AutomapBase.prepare` method, and
+are known as :func:`.classname_for_table`,
+:func:`.name_for_scalar_relationship`,
+and :func:`.name_for_collection_relationship`.  Any or all of these
+functions are provided as in the example below, where we use a "camel case"
+scheme for class names and a "pluralizer" for collection names using the
+`Inflect <https://pypi.python.org/pypi/inflect>`_ package::
+
+    import re
+    import inflect
+
+    def camelize_classname(base, tablename, table):
+        "Produce a 'camelized' class name, e.g. "
+        "'words_and_underscores' -> 'WordsAndUnderscores'"
+
+        return str(tablename[0].upper() + \\
+                re.sub(r'_(\w)', lambda m: m.group(1).upper(), tablename[1:]))
+
+    _pluralizer = inflect.engine()
+    def pluralize_collection(base, local_cls, referred_cls, constraint):
+        "Produce an 'uncamelized', 'pluralized' class name, e.g. "
+        "'SomeTerm' -> 'some_terms'"
+
+        referred_name = referred_cls.__name__
+        uncamelized = referred_name[0].lower() + \\
+                        re.sub(r'\W',
+                                lambda m: "_%s" % m.group(0).lower(),
+                                referred_name[1:])
+        pluralized = _pluralizer.plural(uncamelized)
+        return pluralized
+
+    from sqlalchemy.ext.automap import automap_base
+
+    Base = automap_base()
+
+    engine = create_engine("sqlite:///mydatabase.db")
+
+    Base.prepare(engine, reflect=True,
+                classname_for_table=camelize_classname,
+                name_for_collection_relationship=pluralize_collection
+        )
+
+From the above mapping, we would now have classes ``User`` and ``Address``,
+where the collection from ``User`` to ``Address`` is called
+``User.addresses``::
+
+    User, Address = Base.classes.User, Base.classes.Address
+
+    u1 = User(addresses=[Address(email="foo@bar.com")])
+
+Relationship Detection
+======================
+
+The vast majority of what automap accomplishes is the generation of
+:func:`.relationship` structures based on foreign keys.  The mechanism
+by which this works for many-to-one and one-to-many relationships is as
+follows:
+
+1. A given :class:`.Table`, known to be mapped to a particular class,
+   is examined for :class:`.ForeignKeyConstraint` objects.
+
+2. From each :class:`.ForeignKeyConstraint`, the remote :class:`.Table`
+   object present is matched up to the class to which it is to be mapped,
+   if any, else it is skipped.
+
+3. As the :class:`.ForeignKeyConstraint` we are examining corresponds to a
+   reference from the immediate mapped class,  the relationship will be set up
+   as a many-to-one referring to the referred class; a corresponding
+   one-to-many backref will be created on the referred class referring
+   to this class.
+
+4. The names of the relationships are determined using the
+   :paramref:`.AutomapBase.prepare.name_for_scalar_relationship` and
+   :paramref:`.AutomapBase.prepare.name_for_collection_relationship`
+   callable functions.  It is important to note that the default relationship
+   naming derives the name from the **the actual class name**.  If you've
+   given a particular class an explicit name by declaring it, or specified an
+   alternate class naming scheme, that's the name from which the relationship
+   name will be derived.
+
+5. The classes are inspected for an existing mapped property matching these
+   names.  If one is detected on one side, but none on the other side,
+   :class:`.AutomapBase` attempts to create a relationship on the missing side,
+   then uses the :paramref:`.relationship.back_populates` parameter in order to
+   point the new relationship to the other side.
+
+6. In the usual case where no relationship is on either side,
+   :meth:`.AutomapBase.prepare` produces a :func:`.relationship` on the
+   "many-to-one" side and matches it to the other using the
+   :paramref:`.relationship.backref` parameter.
+
+7. Production of the :func:`.relationship` and optionally the :func:`.backref`
+   is handed off to the :paramref:`.AutomapBase.prepare.generate_relationship`
+   function, which can be supplied by the end-user in order to augment
+   the arguments passed to :func:`.relationship` or :func:`.backref` or to
+   make use of custom implementations of these functions.
+
+Custom Relationship Arguments
+-----------------------------
+
+The :paramref:`.AutomapBase.prepare.generate_relationship` hook can be used
+to add parameters to relationships.  For most cases, we can make use of the
+existing :func:`.automap.generate_relationship` function to return
+the object, after augmenting the given keyword dictionary with our own
+arguments.
+
+Below is an illustration of how to send
+:paramref:`.relationship.cascade` and
+:paramref:`.relationship.passive_deletes`
+options along to all one-to-many relationships::
+
+    from sqlalchemy.ext.automap import generate_relationship
+
+    def _gen_relationship(base, direction, return_fn,
+                                    attrname, local_cls, referred_cls, **kw):
+        if direction is interfaces.ONETOMANY:
+            kw['cascade'] = 'all, delete-orphan'
+            kw['passive_deletes'] = True
+        # make use of the built-in function to actually return
+        # the result.
+        return generate_relationship(base, direction, return_fn,
+                                     attrname, local_cls, referred_cls, **kw)
+
+    from sqlalchemy.ext.automap import automap_base
+    from sqlalchemy import create_engine
+
+    # automap base
+    Base = automap_base()
+
+    engine = create_engine("sqlite:///mydatabase.db")
+    Base.prepare(engine, reflect=True,
+                generate_relationship=_gen_relationship)
+
+Many-to-Many relationships
+--------------------------
+
+:mod:`.sqlalchemy.ext.automap` will generate many-to-many relationships, e.g.
+those which contain a ``secondary`` argument.  The process for producing these
+is as follows:
+
+1. A given :class:`.Table` is examined for :class:`.ForeignKeyConstraint`
+   objects, before any mapped class has been assigned to it.
+
+2. If the table contains two and exactly two :class:`.ForeignKeyConstraint`
+   objects, and all columns within this table are members of these two
+   :class:`.ForeignKeyConstraint` objects, the table is assumed to be a
+   "secondary" table, and will **not be mapped directly**.
+
+3. The two (or one, for self-referential) external tables to which the
+   :class:`.Table` refers to are matched to the classes to which they will be
+   mapped, if any.
+
+4. If mapped classes for both sides are located, a many-to-many bi-directional
+   :func:`.relationship` / :func:`.backref` pair is created between the two
+   classes.
+
+5. The override logic for many-to-many works the same as that of one-to-many/
+   many-to-one; the :func:`.generate_relationship` function is called upon
+   to generate the strucures and existing attributes will be maintained.
+
+Relationships with Inheritance
+------------------------------
+
+:mod:`.sqlalchemy.ext.automap` will not generate any relationships between
+two classes that are in an inheritance relationship.   That is, with two
+classes given as follows::
+
+    class Employee(Base):
+        __tablename__ = 'employee'
+        id = Column(Integer, primary_key=True)
+        type = Column(String(50))
+        __mapper_args__ = {
+             'polymorphic_identity':'employee', 'polymorphic_on': type
+        }
+
+    class Engineer(Employee):
+        __tablename__ = 'engineer'
+        id = Column(Integer, ForeignKey('employee.id'), primary_key=True)
+        __mapper_args__ = {
+            'polymorphic_identity':'engineer',
+        }
+
+The foreign key from ``Engineer`` to ``Employee`` is used not for a
+relationship, but to establish joined inheritance between the two classes.
+
+Note that this means automap will not generate *any* relationships
+for foreign keys that link from a subclass to a superclass.  If a mapping
+has actual relationships from subclass to superclass as well, those
+need to be explicit.  Below, as we have two separate foreign keys
+from ``Engineer`` to ``Employee``, we need to set up both the relationship
+we want as well as the ``inherit_condition``, as these are not things
+SQLAlchemy can guess::
+
+    class Employee(Base):
+        __tablename__ = 'employee'
+        id = Column(Integer, primary_key=True)
+        type = Column(String(50))
+
+        __mapper_args__ = {
+            'polymorphic_identity':'employee', 'polymorphic_on':type
+        }
+
+    class Engineer(Employee):
+        __tablename__ = 'engineer'
+        id = Column(Integer, ForeignKey('employee.id'), primary_key=True)
+        favorite_employee_id = Column(Integer, ForeignKey('employee.id'))
+
+        favorite_employee = relationship(Employee,
+                                         foreign_keys=favorite_employee_id)
+
+        __mapper_args__ = {
+            'polymorphic_identity':'engineer',
+            'inherit_condition': id == Employee.id
+        }
+
+Handling Simple Naming Conflicts
+--------------------------------
+
+In the case of naming conflicts during mapping, override any of
+:func:`.classname_for_table`, :func:`.name_for_scalar_relationship`,
+and :func:`.name_for_collection_relationship` as needed.  For example, if
+automap is attempting to name a many-to-one relationship the same as an
+existing column, an alternate convention can be conditionally selected.  Given
+a schema:
+
+.. sourcecode:: sql
+
+    CREATE TABLE table_a (
+        id INTEGER PRIMARY KEY
+    );
+
+    CREATE TABLE table_b (
+        id INTEGER PRIMARY KEY,
+        table_a INTEGER,
+        FOREIGN KEY(table_a) REFERENCES table_a(id)
+    );
+
+The above schema will first automap the ``table_a`` table as a class named
+``table_a``; it will then automap a relationship onto the class for ``table_b``
+with the same name as this related class, e.g. ``table_a``.  This
+relationship name conflicts with the mapping column ``table_b.table_a``,
+and will emit an error on mapping.
+
+We can resolve this conflict by using an underscore as follows::
+
+    def name_for_scalar_relationship(base, local_cls, referred_cls, constraint):
+        name = referred_cls.__name__.lower()
+        local_table = local_cls.__table__
+        if name in local_table.columns:
+            newname = name + "_"
+            warnings.warn(
+                "Already detected name %s present.  using %s" %
+                (name, newname))
+            return newname
+        return name
+
+
+    Base.prepare(engine, reflect=True,
+        name_for_scalar_relationship=name_for_scalar_relationship)
+
+Alternatively, we can change the name on the column side.   The columns
+that are mapped can be modified using the technique described at
+:ref:`mapper_column_distinct_names`, by assigning the column explicitly
+to a new name::
+
+    Base = automap_base()
+
+    class TableB(Base):
+        __tablename__ = 'table_b'
+        _table_a = Column('table_a', ForeignKey('table_a.id'))
+
+    Base.prepare(engine, reflect=True)
+
+
+Using Automap with Explicit Declarations
+========================================
+
+As noted previously, automap has no dependency on reflection, and can make
+use of any collection of :class:`.Table` objects within a :class:`.MetaData`
+collection.  From this, it follows that automap can also be used
+generate missing relationships given an otherwise complete model that fully
+defines table metadata::
+
+    from sqlalchemy.ext.automap import automap_base
+    from sqlalchemy import Column, Integer, String, ForeignKey
+
+    Base = automap_base()
+
+    class User(Base):
+        __tablename__ = 'user'
+
+        id = Column(Integer, primary_key=True)
+        name = Column(String)
+
+    class Address(Base):
+        __tablename__ = 'address'
+
+        id = Column(Integer, primary_key=True)
+        email = Column(String)
+        user_id = Column(ForeignKey('user.id'))
+
+    # produce relationships
+    Base.prepare()
+
+    # mapping is complete, with "address_collection" and
+    # "user" relationships

+"""Provides an API for creation of custom ClauseElements and compilers.
+
+Synopsis
+========
+
+Usage involves the creation of one or more
+:class:`~sqlalchemy.sql.expression.ClauseElement` subclasses and one or
+more callables defining its compilation::
+
+    from sqlalchemy.ext.compiler import compiles
+    from sqlalchemy.sql.expression import ColumnClause
+
+    class MyColumn(ColumnClause):
+        pass
+
+    @compiles(MyColumn)
+    def compile_mycolumn(element, compiler, **kw):
+        return "[%s]" % element.name
+
+Above, ``MyColumn`` extends :class:`~sqlalchemy.sql.expression.ColumnClause`,
+the base expression element for named column objects. The ``compiles``
+decorator registers itself with the ``MyColumn`` class so that it is invoked
+when the object is compiled to a string::
+
+    from sqlalchemy import select
+
+    s = select([MyColumn('x'), MyColumn('y')])
+    print str(s)
+
+Produces::
+
+    SELECT [x], [y]
+
+Dialect-specific compilation rules
+==================================
+
+Compilers can also be made dialect-specific. The appropriate compiler will be
+invoked for the dialect in use::
+
+    from sqlalchemy.schema import DDLElement
+
+    class AlterColumn(DDLElement):
+
+        def __init__(self, column, cmd):
+            self.column = column
+            self.cmd = cmd
+
+    @compiles(AlterColumn)
+    def visit_alter_column(element, compiler, **kw):
+        return "ALTER COLUMN %s ..." % element.column.name
+
+    @compiles(AlterColumn, 'postgresql')
+    def visit_alter_column(element, compiler, **kw):
+        return "ALTER TABLE %s ALTER COLUMN %s ..." % (element.table.name,
+                                                       element.column.name)
+
+The second ``visit_alter_table`` will be invoked when any ``postgresql``
+dialect is used.
+
+Compiling sub-elements of a custom expression construct
+=======================================================
+
+The ``compiler`` argument is the
+:class:`~sqlalchemy.engine.interfaces.Compiled` object in use. This object
+can be inspected for any information about the in-progress compilation,
+including ``compiler.dialect``, ``compiler.statement`` etc. The
+:class:`~sqlalchemy.sql.compiler.SQLCompiler` and
+:class:`~sqlalchemy.sql.compiler.DDLCompiler` both include a ``process()``
+method which can be used for compilation of embedded attributes::
+
+    from sqlalchemy.sql.expression import Executable, ClauseElement
+
+    class InsertFromSelect(Executable, ClauseElement):
+        def __init__(self, table, select):
+            self.table = table
+            self.select = select
+
+    @compiles(InsertFromSelect)
+    def visit_insert_from_select(element, compiler, **kw):
+        return "INSERT INTO %s (%s)" % (
+            compiler.process(element.table, asfrom=True),
+            compiler.process(element.select)
+        )
+
+    insert = InsertFromSelect(t1, select([t1]).where(t1.c.x>5))
+    print insert
+
+Produces::
+
+    "INSERT INTO mytable (SELECT mytable.x, mytable.y, mytable.z
+                          FROM mytable WHERE mytable.x > :x_1)"
+
+.. note::
+
+    The above ``InsertFromSelect`` construct is only an example, this actual
+    functionality is already available using the
+    :meth:`.Insert.from_select` method.
+
+.. note::
+
+   The above ``InsertFromSelect`` construct probably wants to have "autocommit"
+   enabled.  See :ref:`enabling_compiled_autocommit` for this step.
+
+Cross Compiling between SQL and DDL compilers
+---------------------------------------------
+
+SQL and DDL constructs are each compiled using different base compilers -
+``SQLCompiler`` and ``DDLCompiler``.   A common need is to access the
+compilation rules of SQL expressions from within a DDL expression. The
+``DDLCompiler`` includes an accessor ``sql_compiler`` for this reason, such as
+below where we generate a CHECK constraint that embeds a SQL expression::
+
+    @compiles(MyConstraint)
+    def compile_my_constraint(constraint, ddlcompiler, **kw):
+        return "CONSTRAINT %s CHECK (%s)" % (
+            constraint.name,
+            ddlcompiler.sql_compiler.process(constraint.expression)
+        )
+
+.. _enabling_compiled_autocommit:
+
+Enabling Autocommit on a Construct
+==================================
+
+Recall from the section :ref:`autocommit` that the :class:`.Engine`, when
+asked to execute a construct in the absence of a user-defined transaction,
+detects if the given construct represents DML or DDL, that is, a data
+modification or data definition statement, which requires (or may require,
+in the case of DDL) that the transaction generated by the DBAPI be committed
+(recall that DBAPI always has a transaction going on regardless of what
+SQLAlchemy does).   Checking for this is actually accomplished by checking for
+the "autocommit" execution option on the construct.    When building a
+construct like an INSERT derivation, a new DDL type, or perhaps a stored
+procedure that alters data, the "autocommit" option needs to be set in order
+for the statement to function with "connectionless" execution
+(as described in :ref:`dbengine_implicit`).
+
+Currently a quick way to do this is to subclass :class:`.Executable`, then
+add the "autocommit" flag to the ``_execution_options`` dictionary (note this
+is a "frozen" dictionary which supplies a generative ``union()`` method)::
+
+    from sqlalchemy.sql.expression import Executable, ClauseElement
+
+    class MyInsertThing(Executable, ClauseElement):
+        _execution_options = \\
+            Executable._execution_options.union({'autocommit': True})
+
+More succinctly, if the construct is truly similar to an INSERT, UPDATE, or
+DELETE, :class:`.UpdateBase` can be used, which already is a subclass
+of :class:`.Executable`, :class:`.ClauseElement` and includes the
+``autocommit`` flag::
+
+    from sqlalchemy.sql.expression import UpdateBase
+
+    class MyInsertThing(UpdateBase):
+        def __init__(self, ...):
+            ...
+
+
+
+
+DDL elements that subclass :class:`.DDLElement` already have the
+"autocommit" flag turned on.
+
+
+
+
+Changing the default compilation of existing constructs
+=======================================================
+
+The compiler extension applies just as well to the existing constructs.  When
+overriding the compilation of a built in SQL construct, the @compiles
+decorator is invoked upon the appropriate class (be sure to use the class,
+i.e. ``Insert`` or ``Select``, instead of the creation function such
+as ``insert()`` or ``select()``).
+
+Within the new compilation function, to get at the "original" compilation
+routine, use the appropriate visit_XXX method - this
+because compiler.process() will call upon the overriding routine and cause
+an endless loop.   Such as, to add "prefix" to all insert statements::
+
+    from sqlalchemy.sql.expression import Insert
+
+    @compiles(Insert)
+    def prefix_inserts(insert, compiler, **kw):
+        return compiler.visit_insert(insert.prefix_with("some prefix"), **kw)
+
+The above compiler will prefix all INSERT statements with "some prefix" when
+compiled.
+
+.. _type_compilation_extension:
+
+Changing Compilation of Types
+=============================
+
+``compiler`` works for types, too, such as below where we implement the
+MS-SQL specific 'max' keyword for ``String``/``VARCHAR``::
+
+    @compiles(String, 'mssql')
+    @compiles(VARCHAR, 'mssql')
+    def compile_varchar(element, compiler, **kw):
+        if element.length == 'max':
+            return "VARCHAR('max')"
+        else:
+            return compiler.visit_VARCHAR(element, **kw)
+
+    foo = Table('foo', metadata,
+        Column('data', VARCHAR('max'))
+    )
+
+Subclassing Guidelines
+======================
+
+A big part of using the compiler extension is subclassing SQLAlchemy
+expression constructs. To make this easier, the expression and
+schema packages feature a set of "bases" intended for common tasks.
+A synopsis is as follows:
+
+* :class:`~sqlalchemy.sql.expression.ClauseElement` - This is the root
+  expression class. Any SQL expression can be derived from this base, and is
+  probably the best choice for longer constructs such as specialized INSERT
+  statements.
+
+* :class:`~sqlalchemy.sql.expression.ColumnElement` - The root of all
+  "column-like" elements. Anything that you'd place in the "columns" clause of
+  a SELECT statement (as well as order by and group by) can derive from this -
+  the object will automatically have Python "comparison" behavior.
+
+  :class:`~sqlalchemy.sql.expression.ColumnElement` classes want to have a
+  ``type`` member which is expression's return type.  This can be established
+  at the instance level in the constructor, or at the class level if its
+  generally constant::
+
+      class timestamp(ColumnElement):
+          type = TIMESTAMP()
+
+* :class:`~sqlalchemy.sql.functions.FunctionElement` - This is a hybrid of a
+  ``ColumnElement`` and a "from clause" like object, and represents a SQL
+  function or stored procedure type of call. Since most databases support
+  statements along the line of "SELECT FROM <some function>"
+  ``FunctionElement`` adds in the ability to be used in the FROM clause of a
+  ``select()`` construct::
+
+      from sqlalchemy.sql.expression import FunctionElement
+
+      class coalesce(FunctionElement):
+          name = 'coalesce'
+
+      @compiles(coalesce)
+      def compile(element, compiler, **kw):
+          return "coalesce(%s)" % compiler.process(element.clauses)
+
+      @compiles(coalesce, 'oracle')
+      def compile(element, compiler, **kw):
+          if len(element.clauses) > 2:
+              raise TypeError("coalesce only supports two arguments on Oracle")
+          return "nvl(%s)" % compiler.process(element.clauses)
+
+* :class:`~sqlalchemy.schema.DDLElement` - The root of all DDL expressions,
+  like CREATE TABLE, ALTER TABLE, etc. Compilation of ``DDLElement``
+  subclasses is issued by a ``DDLCompiler`` instead of a ``SQLCompiler``.
+  ``DDLElement`` also features ``Table`` and ``MetaData`` event hooks via the
+  ``execute_at()`` method, allowing the construct to be invoked during CREATE
+  TABLE and DROP TABLE sequences.
+
+* :class:`~sqlalchemy.sql.expression.Executable` - This is a mixin which
+  should be used with any expression class that represents a "standalone"
+  SQL statement that can be passed directly to an ``execute()`` method.  It
+  is already implicit within ``DDLElement`` and ``FunctionElement``.
+
+Further Examples
+================
+
+"UTC timestamp" function
+-------------------------
+
+A function that works like "CURRENT_TIMESTAMP" except applies the
+appropriate conversions so that the time is in UTC time.   Timestamps are best
+stored in relational databases as UTC, without time zones.   UTC so that your
+database doesn't think time has gone backwards in the hour when daylight
+savings ends, without timezones because timezones are like character
+encodings - they're best applied only at the endpoints of an application
+(i.e. convert to UTC upon user input, re-apply desired timezone upon display).
+
+For Postgresql and Microsoft SQL Server::
+
+    from sqlalchemy.sql import expression
+    from sqlalchemy.ext.compiler import compiles
+    from sqlalchemy.types import DateTime
+
+    class utcnow(expression.FunctionElement):
+        type = DateTime()
+
+    @compiles(utcnow, 'postgresql')
+    def pg_utcnow(element, compiler, **kw):
+        return "TIMEZONE('utc', CURRENT_TIMESTAMP)"
+
+    @compiles(utcnow, 'mssql')
+    def ms_utcnow(element, compiler, **kw):
+        return "GETUTCDATE()"
+
+Example usage::
+
+    from sqlalchemy import (
+                Table, Column, Integer, String, DateTime, MetaData
+            )
+    metadata = MetaData()
+    event = Table("event", metadata,
+        Column("id", Integer, primary_key=True),
+        Column("description", String(50), nullable=False),
+        Column("timestamp", DateTime, server_default=utcnow())
+    )
+
+"GREATEST" function
+-------------------
+
+The "GREATEST" function is given any number of arguments and returns the one
+that is of the highest value - its equivalent to Python's ``max``
+function.  A SQL standard version versus a CASE based version which only
+accommodates two arguments::
+
+    from sqlalchemy.sql import expression
+    from sqlalchemy.ext.compiler import compiles
+    from sqlalchemy.types import Numeric
+
+    class greatest(expression.FunctionElement):
+        type = Numeric()
+        name = 'greatest'
+
+    @compiles(greatest)
+    def default_greatest(element, compiler, **kw):
+        return compiler.visit_function(element)
+
+    @compiles(greatest, 'sqlite')
+    @compiles(greatest, 'mssql')
+    @compiles(greatest, 'oracle')
+    def case_greatest(element, compiler, **kw):
+        arg1, arg2 = list(element.clauses)
+        return "CASE WHEN %s > %s THEN %s ELSE %s END" % (
+            compiler.process(arg1),
+            compiler.process(arg2),
+            compiler.process(arg1),
+            compiler.process(arg2),
+        )
+
+Example usage::
+
+    Session.query(Account).\\
+            filter(
+                greatest(
+                    Account.checking_balance,
+                    Account.savings_balance) > 10000
+            )
+
+"false" expression
+------------------
+
+Render a "false" constant expression, rendering as "0" on platforms that
+don't have a "false" constant::
+
+    from sqlalchemy.sql import expression
+    from sqlalchemy.ext.compiler import compiles
+
+    class sql_false(expression.ColumnElement):
+        pass
+
+    @compiles(sql_false)
+    def default_false(element, compiler, **kw):
+        return "false"
+
+    @compiles(sql_false, 'mssql')
+    @compiles(sql_false, 'mysql')
+    @compiles(sql_false, 'oracle')
+    def int_false(element, compiler, **kw):
+        return "0"
+
+Example usage::
+
+    from sqlalchemy import select, union_all
+
+    exp = union_all(
+        select([users.c.name, sql_false().label("enrolled")]),
+        select([customers.c.name, customers.c.enrolled])
+    )

+Synopsis
+========
+
+SQLAlchemy object-relational configuration involves the
+combination of :class:`.Table`, :func:`.mapper`, and class
+objects to define a mapped class.
+:mod:`~sqlalchemy.ext.declarative` allows all three to be
+expressed at once within the class declaration. As much as
+possible, regular SQLAlchemy schema and ORM constructs are
+used directly, so that configuration between "classical" ORM
+usage and declarative remain highly similar.
+
+As a simple example::
+
+    from sqlalchemy.ext.declarative import declarative_base
+
+    Base = declarative_base()
+
+    class SomeClass(Base):
+        __tablename__ = 'some_table'
+        id = Column(Integer, primary_key=True)
+        name =  Column(String(50))
+
+Above, the :func:`declarative_base` callable returns a new base class from
+which all mapped classes should inherit. When the class definition is
+completed, a new :class:`.Table` and :func:`.mapper` will have been generated.
+
+The resulting table and mapper are accessible via
+``__table__`` and ``__mapper__`` attributes on the
+``SomeClass`` class::
+
+    # access the mapped Table
+    SomeClass.__table__
+
+    # access the Mapper
+    SomeClass.__mapper__
+
+Defining Attributes
+===================
+
+In the previous example, the :class:`.Column` objects are
+automatically named with the name of the attribute to which they are
+assigned.
+
+To name columns explicitly with a name distinct from their mapped attribute,
+just give the column a name.  Below, column "some_table_id" is mapped to the
+"id" attribute of `SomeClass`, but in SQL will be represented as
+"some_table_id"::
+
+    class SomeClass(Base):
+        __tablename__ = 'some_table'
+        id = Column("some_table_id", Integer, primary_key=True)
+
+Attributes may be added to the class after its construction, and they will be
+added to the underlying :class:`.Table` and
+:func:`.mapper` definitions as appropriate::
+
+    SomeClass.data = Column('data', Unicode)
+    SomeClass.related = relationship(RelatedInfo)
+
+Classes which are constructed using declarative can interact freely
+with classes that are mapped explicitly with :func:`.mapper`.
+
+It is recommended, though not required, that all tables
+share the same underlying :class:`~sqlalchemy.schema.MetaData` object,
+so that string-configured :class:`~sqlalchemy.schema.ForeignKey`
+references can be resolved without issue.
+
+Accessing the MetaData
+=======================
+
+The :func:`declarative_base` base class contains a
+:class:`.MetaData` object where newly defined
+:class:`.Table` objects are collected. This object is
+intended to be accessed directly for
+:class:`.MetaData`-specific operations. Such as, to issue
+CREATE statements for all tables::
+
+    engine = create_engine('sqlite://')
+    Base.metadata.create_all(engine)
+
+:func:`declarative_base` can also receive a pre-existing
+:class:`.MetaData` object, which allows a
+declarative setup to be associated with an already
+existing traditional collection of :class:`~sqlalchemy.schema.Table`
+objects::
+
+    mymetadata = MetaData()
+    Base = declarative_base(metadata=mymetadata)
+
+
+.. _declarative_configuring_relationships:
+
+Configuring Relationships
+=========================
+
+Relationships to other classes are done in the usual way, with the added
+feature that the class specified to :func:`~sqlalchemy.orm.relationship`
+may be a string name.  The "class registry" associated with ``Base``
+is used at mapper compilation time to resolve the name into the actual
+class object, which is expected to have been defined once the mapper
+configuration is used::
+
+    class User(Base):
+        __tablename__ = 'users'
+
+        id = Column(Integer, primary_key=True)
+        name = Column(String(50))
+        addresses = relationship("Address", backref="user")
+
+    class Address(Base):
+        __tablename__ = 'addresses'
+
+        id = Column(Integer, primary_key=True)
+        email = Column(String(50))
+        user_id = Column(Integer, ForeignKey('users.id'))
+
+Column constructs, since they are just that, are immediately usable,
+as below where we define a primary join condition on the ``Address``
+class using them::
+
+    class Address(Base):
+        __tablename__ = 'addresses'
+
+        id = Column(Integer, primary_key=True)
+        email = Column(String(50))
+        user_id = Column(Integer, ForeignKey('users.id'))
+        user = relationship(User, primaryjoin=user_id == User.id)
+
+In addition to the main argument for :func:`~sqlalchemy.orm.relationship`,
+other arguments which depend upon the columns present on an as-yet
+undefined class may also be specified as strings.  These strings are
+evaluated as Python expressions.  The full namespace available within
+this evaluation includes all classes mapped for this declarative base,
+as well as the contents of the ``sqlalchemy`` package, including
+expression functions like :func:`~sqlalchemy.sql.expression.desc` and
+:attr:`~sqlalchemy.sql.expression.func`::
+
+    class User(Base):
+        # ....
+        addresses = relationship("Address",
+                             order_by="desc(Address.email)",
+                             primaryjoin="Address.user_id==User.id")
+
+For the case where more than one module contains a class of the same name,
+string class names can also be specified as module-qualified paths
+within any of these string expressions::
+
+    class User(Base):
+        # ....
+        addresses = relationship("myapp.model.address.Address",
+                             order_by="desc(myapp.model.address.Address.email)",
+                             primaryjoin="myapp.model.address.Address.user_id=="
+                                            "myapp.model.user.User.id")
+
+The qualified path can be any partial path that removes ambiguity between
+the names.  For example, to disambiguate between
+``myapp.model.address.Address`` and ``myapp.model.lookup.Address``,
+we can specify ``address.Address`` or ``lookup.Address``::
+
+    class User(Base):
+        # ....
+        addresses = relationship("address.Address",
+                             order_by="desc(address.Address.email)",
+                             primaryjoin="address.Address.user_id=="
+                                            "User.id")
+
+.. versionadded:: 0.8
+   module-qualified paths can be used when specifying string arguments
+   with Declarative, in order to specify specific modules.
+
+Two alternatives also exist to using string-based attributes.  A lambda
+can also be used, which will be evaluated after all mappers have been
+configured::
+
+    class User(Base):
+        # ...
+        addresses = relationship(lambda: Address,
+                             order_by=lambda: desc(Address.email),
+                             primaryjoin=lambda: Address.user_id==User.id)
+
+Or, the relationship can be added to the class explicitly after the classes
+are available::
+
+    User.addresses = relationship(Address,
+                              primaryjoin=Address.user_id==User.id)
+
+
+
+.. _declarative_many_to_many:
+
+Configuring Many-to-Many Relationships
+======================================
+
+Many-to-many relationships are also declared in the same way
+with declarative as with traditional mappings. The
+``secondary`` argument to
+:func:`.relationship` is as usual passed a
+:class:`.Table` object, which is typically declared in the
+traditional way.  The :class:`.Table` usually shares
+the :class:`.MetaData` object used by the declarative base::
+
+    keywords = Table(
+        'keywords', Base.metadata,
+        Column('author_id', Integer, ForeignKey('authors.id')),
+        Column('keyword_id', Integer, ForeignKey('keywords.id'))
+        )
+
+    class Author(Base):
+        __tablename__ = 'authors'
+        id = Column(Integer, primary_key=True)
+        keywords = relationship("Keyword", secondary=keywords)
+
+Like other :func:`~sqlalchemy.orm.relationship` arguments, a string is accepted
+as well, passing the string name of the table as defined in the
+``Base.metadata.tables`` collection::
+
+    class Author(Base):
+        __tablename__ = 'authors'
+        id = Column(Integer, primary_key=True)
+        keywords = relationship("Keyword", secondary="keywords")
+
+As with traditional mapping, its generally not a good idea to use
+a :class:`.Table` as the "secondary" argument which is also mapped to
+a class, unless the :func:`.relationship` is declared with ``viewonly=True``.
+Otherwise, the unit-of-work system may attempt duplicate INSERT and
+DELETE statements against the underlying table.
+
+.. _declarative_sql_expressions:
+
+Defining SQL Expressions
+========================
+
+See :ref:`mapper_sql_expressions` for examples on declaratively
+mapping attributes to SQL expressions.
+
+.. _declarative_table_args:
+
+Table Configuration
+===================
+
+Table arguments other than the name, metadata, and mapped Column
+arguments are specified using the ``__table_args__`` class attribute.
+This attribute accommodates both positional as well as keyword
+arguments that are normally sent to the
+:class:`~sqlalchemy.schema.Table` constructor.
+The attribute can be specified in one of two forms. One is as a
+dictionary::
+
+    class MyClass(Base):
+        __tablename__ = 'sometable'
+        __table_args__ = {'mysql_engine':'InnoDB'}
+
+The other, a tuple, where each argument is positional
+(usually constraints)::
+
+    class MyClass(Base):
+        __tablename__ = 'sometable'
+        __table_args__ = (
+                ForeignKeyConstraint(['id'], ['remote_table.id']),
+                UniqueConstraint('foo'),
+                )
+
+Keyword arguments can be specified with the above form by
+specifying the last argument as a dictionary::
+
+    class MyClass(Base):
+        __tablename__ = 'sometable'
+        __table_args__ = (
+                ForeignKeyConstraint(['id'], ['remote_table.id']),
+                UniqueConstraint('foo'),
+                {'autoload':True}
+                )
+
+Using a Hybrid Approach with __table__
+=======================================
+
+As an alternative to ``__tablename__``, a direct
+:class:`~sqlalchemy.schema.Table` construct may be used.  The
+:class:`~sqlalchemy.schema.Column` objects, which in this case require
+their names, will be added to the mapping just like a regular mapping
+to a table::
+
+    class MyClass(Base):
+        __table__ = Table('my_table', Base.metadata,
+            Column('id', Integer, primary_key=True),
+            Column('name', String(50))
+        )
+
+``__table__`` provides a more focused point of control for establishing
+table metadata, while still getting most of the benefits of using declarative.
+An application that uses reflection might want to load table metadata elsewhere
+and pass it to declarative classes::
+
+    from sqlalchemy.ext.declarative import declarative_base
+
+    Base = declarative_base()
+    Base.metadata.reflect(some_engine)
+
+    class User(Base):
+        __table__ = metadata.tables['user']
+
+    class Address(Base):
+        __table__ = metadata.tables['address']
+
+Some configuration schemes may find it more appropriate to use ``__table__``,
+such as those which already take advantage of the data-driven nature of
+:class:`.Table` to customize and/or automate schema definition.
+
+Note that when the ``__table__`` approach is used, the object is immediately
+usable as a plain :class:`.Table` within the class declaration body itself,
+as a Python class is only another syntactical block.  Below this is illustrated
+by using the ``id`` column in the ``primaryjoin`` condition of a
+:func:`.relationship`::
+
+    class MyClass(Base):
+        __table__ = Table('my_table', Base.metadata,
+            Column('id', Integer, primary_key=True),
+            Column('name', String(50))
+        )
+
+        widgets = relationship(Widget,
+                    primaryjoin=Widget.myclass_id==__table__.c.id)
+
+Similarly, mapped attributes which refer to ``__table__`` can be placed inline,
+as below where we assign the ``name`` column to the attribute ``_name``,
+generating a synonym for ``name``::
+
+    from sqlalchemy.ext.declarative import synonym_for
+
+    class MyClass(Base):
+        __table__ = Table('my_table', Base.metadata,
+            Column('id', Integer, primary_key=True),
+            Column('name', String(50))
+        )
+
+        _name = __table__.c.name
+
+        @synonym_for("_name")
+        def name(self):
+            return "Name: %s" % _name
+
+Using Reflection with Declarative
+=================================
+
+It's easy to set up a :class:`.Table` that uses ``autoload=True``
+in conjunction with a mapped class::
+
+    class MyClass(Base):
+        __table__ = Table('mytable', Base.metadata,
+                        autoload=True, autoload_with=some_engine)
+
+However, one improvement that can be made here is to not
+require the :class:`.Engine` to be available when classes are
+being first declared.   To achieve this, use the
+:class:`.DeferredReflection` mixin, which sets up mappings
+only after a special ``prepare(engine)`` step is called::
+
+    from sqlalchemy.ext.declarative import declarative_base, DeferredReflection
+
+    Base = declarative_base(cls=DeferredReflection)
+
+    class Foo(Base):
+        __tablename__ = 'foo'
+        bars = relationship("Bar")
+
+    class Bar(Base):
+        __tablename__ = 'bar'
+
+        # illustrate overriding of "bar.foo_id" to have
+        # a foreign key constraint otherwise not
+        # reflected, such as when using MySQL
+        foo_id = Column(Integer, ForeignKey('foo.id'))
+
+    Base.prepare(e)
+
+.. versionadded:: 0.8
+   Added :class:`.DeferredReflection`.
+
+Mapper Configuration
+====================
+
+Declarative makes use of the :func:`~.orm.mapper` function internally
+when it creates the mapping to the declared table.   The options
+for :func:`~.orm.mapper` are passed directly through via the
+``__mapper_args__`` class attribute.  As always, arguments which reference
+locally mapped columns can reference them directly from within the
+class declaration::
+
+    from datetime import datetime
+
+    class Widget(Base):
+        __tablename__ = 'widgets'
+
+        id = Column(Integer, primary_key=True)
+        timestamp = Column(DateTime, nullable=False)
+
+        __mapper_args__ = {
+                        'version_id_col': timestamp,
+                        'version_id_generator': lambda v:datetime.now()
+                    }
+
+.. _declarative_inheritance:
+
+Inheritance Configuration
+=========================
+
+Declarative supports all three forms of inheritance as intuitively
+as possible.  The ``inherits`` mapper keyword argument is not needed
+as declarative will determine this from the class itself.   The various
+"polymorphic" keyword arguments are specified using ``__mapper_args__``.
+
+Joined Table Inheritance
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Joined table inheritance is defined as a subclass that defines its own
+table::
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        __tablename__ = 'engineers'
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+        id = Column(Integer, ForeignKey('people.id'), primary_key=True)
+        primary_language = Column(String(50))
+
+Note that above, the ``Engineer.id`` attribute, since it shares the
+same attribute name as the ``Person.id`` attribute, will in fact
+represent the ``people.id`` and ``engineers.id`` columns together,
+with the "Engineer.id" column taking precedence if queried directly.
+To provide the ``Engineer`` class with an attribute that represents
+only the ``engineers.id`` column, give it a different attribute name::
+
+    class Engineer(Person):
+        __tablename__ = 'engineers'
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+        engineer_id = Column('id', Integer, ForeignKey('people.id'),
+                                                    primary_key=True)
+        primary_language = Column(String(50))
+
+
+.. versionchanged:: 0.7 joined table inheritance favors the subclass
+   column over that of the superclass, such as querying above
+   for ``Engineer.id``.  Prior to 0.7 this was the reverse.
+
+.. _declarative_single_table:
+
+Single Table Inheritance
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Single table inheritance is defined as a subclass that does not have
+its own table; you just leave out the ``__table__`` and ``__tablename__``
+attributes::
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+        primary_language = Column(String(50))
+
+When the above mappers are configured, the ``Person`` class is mapped
+to the ``people`` table *before* the ``primary_language`` column is
+defined, and this column will not be included in its own mapping.
+When ``Engineer`` then defines the ``primary_language`` column, the
+column is added to the ``people`` table so that it is included in the
+mapping for ``Engineer`` and is also part of the table's full set of
+columns.  Columns which are not mapped to ``Person`` are also excluded
+from any other single or joined inheriting classes using the
+``exclude_properties`` mapper argument.  Below, ``Manager`` will have
+all the attributes of ``Person`` and ``Manager`` but *not* the
+``primary_language`` attribute of ``Engineer``::
+
+    class Manager(Person):
+        __mapper_args__ = {'polymorphic_identity': 'manager'}
+        golf_swing = Column(String(50))
+
+The attribute exclusion logic is provided by the
+``exclude_properties`` mapper argument, and declarative's default
+behavior can be disabled by passing an explicit ``exclude_properties``
+collection (empty or otherwise) to the ``__mapper_args__``.
+
+Resolving Column Conflicts
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Note above that the ``primary_language`` and ``golf_swing`` columns
+are "moved up" to be applied to ``Person.__table__``, as a result of their
+declaration on a subclass that has no table of its own.   A tricky case
+comes up when two subclasses want to specify *the same* column, as below::
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+        start_date = Column(DateTime)
+
+    class Manager(Person):
+        __mapper_args__ = {'polymorphic_identity': 'manager'}
+        start_date = Column(DateTime)
+
+Above, the ``start_date`` column declared on both ``Engineer`` and ``Manager``
+will result in an error::
+
+    sqlalchemy.exc.ArgumentError: Column 'start_date' on class
+    <class '__main__.Manager'> conflicts with existing
+    column 'people.start_date'
+
+In a situation like this, Declarative can't be sure
+of the intent, especially if the ``start_date`` columns had, for example,
+different types.   A situation like this can be resolved by using
+:class:`.declared_attr` to define the :class:`.Column` conditionally, taking
+care to return the **existing column** via the parent ``__table__`` if it
+already exists::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+
+        @declared_attr
+        def start_date(cls):
+            "Start date column, if not present already."
+            return Person.__table__.c.get('start_date', Column(DateTime))
+
+    class Manager(Person):
+        __mapper_args__ = {'polymorphic_identity': 'manager'}
+
+        @declared_attr
+        def start_date(cls):
+            "Start date column, if not present already."
+            return Person.__table__.c.get('start_date', Column(DateTime))
+
+Above, when ``Manager`` is mapped, the ``start_date`` column is
+already present on the ``Person`` class.  Declarative lets us return
+that :class:`.Column` as a result in this case, where it knows to skip
+re-assigning the same column. If the mapping is mis-configured such
+that the ``start_date`` column is accidentally re-assigned to a
+different table (such as, if we changed ``Manager`` to be joined
+inheritance without fixing ``start_date``), an error is raised which
+indicates an existing :class:`.Column` is trying to be re-assigned to
+a different owning :class:`.Table`.
+
+.. versionadded:: 0.8 :class:`.declared_attr` can be used on a non-mixin
+   class, and the returned :class:`.Column` or other mapped attribute
+   will be applied to the mapping as any other attribute.  Previously,
+   the resulting attribute would be ignored, and also result in a warning
+   being emitted when a subclass was created.
+
+.. versionadded:: 0.8 :class:`.declared_attr`, when used either with a
+   mixin or non-mixin declarative class, can return an existing
+   :class:`.Column` already assigned to the parent :class:`.Table`,
+   to indicate that the re-assignment of the :class:`.Column` should be
+   skipped, however should still be mapped on the target class,
+   in order to resolve duplicate column conflicts.
+
+The same concept can be used with mixin classes (see
+:ref:`declarative_mixins`)::
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class HasStartDate(object):
+        @declared_attr
+        def start_date(cls):
+            return cls.__table__.c.get('start_date', Column(DateTime))
+
+    class Engineer(HasStartDate, Person):
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+
+    class Manager(HasStartDate, Person):
+        __mapper_args__ = {'polymorphic_identity': 'manager'}
+
+The above mixin checks the local ``__table__`` attribute for the column.
+Because we're using single table inheritance, we're sure that in this case,
+``cls.__table__`` refers to ``People.__table__``.  If we were mixing joined-
+and single-table inheritance, we might want our mixin to check more carefully
+if ``cls.__table__`` is really the :class:`.Table` we're looking for.
+
+Concrete Table Inheritance
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Concrete is defined as a subclass which has its own table and sets the
+``concrete`` keyword argument to ``True``::
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        name = Column(String(50))
+
+    class Engineer(Person):
+        __tablename__ = 'engineers'
+        __mapper_args__ = {'concrete':True}
+        id = Column(Integer, primary_key=True)
+        primary_language = Column(String(50))
+        name = Column(String(50))
+
+Usage of an abstract base class is a little less straightforward as it
+requires usage of :func:`~sqlalchemy.orm.util.polymorphic_union`,
+which needs to be created with the :class:`.Table` objects
+before the class is built::
+
+    engineers = Table('engineers', Base.metadata,
+                    Column('id', Integer, primary_key=True),
+                    Column('name', String(50)),
+                    Column('primary_language', String(50))
+                )
+    managers = Table('managers', Base.metadata,
+                    Column('id', Integer, primary_key=True),
+                    Column('name', String(50)),
+                    Column('golf_swing', String(50))
+                )
+
+    punion = polymorphic_union({
+        'engineer':engineers,
+        'manager':managers
+    }, 'type', 'punion')
+
+    class Person(Base):
+        __table__ = punion
+        __mapper_args__ = {'polymorphic_on':punion.c.type}
+
+    class Engineer(Person):
+        __table__ = engineers
+        __mapper_args__ = {'polymorphic_identity':'engineer', 'concrete':True}
+
+    class Manager(Person):
+        __table__ = managers
+        __mapper_args__ = {'polymorphic_identity':'manager', 'concrete':True}
+
+.. _declarative_concrete_helpers:
+
+Using the Concrete Helpers
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Helper classes provides a simpler pattern for concrete inheritance.
+With these objects, the ``__declare_first__`` helper is used to configure the
+"polymorphic" loader for the mapper after all subclasses have been declared.
+
+.. versionadded:: 0.7.3
+
+An abstract base can be declared using the
+:class:`.AbstractConcreteBase` class::
+
+    from sqlalchemy.ext.declarative import AbstractConcreteBase
+
+    class Employee(AbstractConcreteBase, Base):
+        pass
+
+To have a concrete ``employee`` table, use :class:`.ConcreteBase` instead::
+
+    from sqlalchemy.ext.declarative import ConcreteBase
+
+    class Employee(ConcreteBase, Base):
+        __tablename__ = 'employee'
+        employee_id = Column(Integer, primary_key=True)
+        name = Column(String(50))
+        __mapper_args__ = {
+                        'polymorphic_identity':'employee',
+                        'concrete':True}
+
+
+Either ``Employee`` base can be used in the normal fashion::
+
+    class Manager(Employee):
+        __tablename__ = 'manager'
+        employee_id = Column(Integer, primary_key=True)
+        name = Column(String(50))
+        manager_data = Column(String(40))
+        __mapper_args__ = {
+                        'polymorphic_identity':'manager',
+                        'concrete':True}
+
+    class Engineer(Employee):
+        __tablename__ = 'engineer'
+        employee_id = Column(Integer, primary_key=True)
+        name = Column(String(50))
+        engineer_info = Column(String(40))
+        __mapper_args__ = {'polymorphic_identity':'engineer',
+                        'concrete':True}
+
+
+The :class:`.AbstractConcreteBase` class is itself mapped, and can be
+used as a target of relationships::
+
+    class Company(Base):
+        __tablename__ = 'company'
+
+        id = Column(Integer, primary_key=True)
+        employees = relationship("Employee",
+                        primaryjoin="Company.id == Employee.company_id")
+
+
+.. versionchanged:: 0.9.3 Support for use of :class:`.AbstractConcreteBase`
+   as the target of a :func:`.relationship` has been improved.
+
+It can also be queried directly::
+
+    for employee in session.query(Employee).filter(Employee.name == 'qbert'):
+        print(employee)
+
+
+.. _declarative_mixins:
+
+Mixin and Custom Base Classes
+==============================
+
+A common need when using :mod:`~sqlalchemy.ext.declarative` is to
+share some functionality, such as a set of common columns, some common
+table options, or other mapped properties, across many
+classes.  The standard Python idioms for this is to have the classes
+inherit from a base which includes these common features.
+
+When using :mod:`~sqlalchemy.ext.declarative`, this idiom is allowed
+via the usage of a custom declarative base class, as well as a "mixin" class
+which is inherited from in addition to the primary base.  Declarative
+includes several helper features to make this work in terms of how
+mappings are declared.   An example of some commonly mixed-in
+idioms is below::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class MyMixin(object):
+
+        @declared_attr
+        def __tablename__(cls):
+            return cls.__name__.lower()
+
+        __table_args__ = {'mysql_engine': 'InnoDB'}
+        __mapper_args__= {'always_refresh': True}
+
+        id =  Column(Integer, primary_key=True)
+
+    class MyModel(MyMixin, Base):
+        name = Column(String(1000))
+
+Where above, the class ``MyModel`` will contain an "id" column
+as the primary key, a ``__tablename__`` attribute that derives
+from the name of the class itself, as well as ``__table_args__``
+and ``__mapper_args__`` defined by the ``MyMixin`` mixin class.
+
+There's no fixed convention over whether ``MyMixin`` precedes
+``Base`` or not.  Normal Python method resolution rules apply, and
+the above example would work just as well with::
+
+    class MyModel(Base, MyMixin):
+        name = Column(String(1000))
+
+This works because ``Base`` here doesn't define any of the
+variables that ``MyMixin`` defines, i.e. ``__tablename__``,
+``__table_args__``, ``id``, etc.   If the ``Base`` did define
+an attribute of the same name, the class placed first in the
+inherits list would determine which attribute is used on the
+newly defined class.
+
+Augmenting the Base
+~~~~~~~~~~~~~~~~~~~
+
+In addition to using a pure mixin, most of the techniques in this
+section can also be applied to the base class itself, for patterns that
+should apply to all classes derived from a particular base.  This is achieved
+using the ``cls`` argument of the :func:`.declarative_base` function::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class Base(object):
+        @declared_attr
+        def __tablename__(cls):
+            return cls.__name__.lower()
+
+        __table_args__ = {'mysql_engine': 'InnoDB'}
+
+        id =  Column(Integer, primary_key=True)
+
+    from sqlalchemy.ext.declarative import declarative_base
+
+    Base = declarative_base(cls=Base)
+
+    class MyModel(Base):
+        name = Column(String(1000))
+
+Where above, ``MyModel`` and all other classes that derive from ``Base`` will
+have a table name derived from the class name, an ``id`` primary key column,
+as well as the "InnoDB" engine for MySQL.
+
+Mixing in Columns
+~~~~~~~~~~~~~~~~~
+
+The most basic way to specify a column on a mixin is by simple
+declaration::
+
+    class TimestampMixin(object):
+        created_at = Column(DateTime, default=func.now())
+
+    class MyModel(TimestampMixin, Base):
+        __tablename__ = 'test'
+
+        id =  Column(Integer, primary_key=True)
+        name = Column(String(1000))
+
+Where above, all declarative classes that include ``TimestampMixin``
+will also have a column ``created_at`` that applies a timestamp to
+all row insertions.
+
+Those familiar with the SQLAlchemy expression language know that
+the object identity of clause elements defines their role in a schema.
+Two ``Table`` objects ``a`` and ``b`` may both have a column called
+``id``, but the way these are differentiated is that ``a.c.id``
+and ``b.c.id`` are two distinct Python objects, referencing their
+parent tables ``a`` and ``b`` respectively.
+
+In the case of the mixin column, it seems that only one
+:class:`.Column` object is explicitly created, yet the ultimate
+``created_at`` column above must exist as a distinct Python object
+for each separate destination class.  To accomplish this, the declarative
+extension creates a **copy** of each :class:`.Column` object encountered on
+a class that is detected as a mixin.
+
+This copy mechanism is limited to simple columns that have no foreign
+keys, as a :class:`.ForeignKey` itself contains references to columns
+which can't be properly recreated at this level.  For columns that
+have foreign keys, as well as for the variety of mapper-level constructs
+that require destination-explicit context, the
+:class:`~.declared_attr` decorator is provided so that
+patterns common to many classes can be defined as callables::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class ReferenceAddressMixin(object):
+        @declared_attr
+        def address_id(cls):
+            return Column(Integer, ForeignKey('address.id'))
+
+    class User(ReferenceAddressMixin, Base):
+        __tablename__ = 'user'
+        id = Column(Integer, primary_key=True)
+
+Where above, the ``address_id`` class-level callable is executed at the
+point at which the ``User`` class is constructed, and the declarative
+extension can use the resulting :class:`.Column` object as returned by
+the method without the need to copy it.
+
+.. versionchanged:: > 0.6.5
+    Rename 0.6.5 ``sqlalchemy.util.classproperty``
+    into :class:`~.declared_attr`.
+
+Columns generated by :class:`~.declared_attr` can also be
+referenced by ``__mapper_args__`` to a limited degree, currently
+by ``polymorphic_on`` and ``version_id_col``, by specifying the
+classdecorator itself into the dictionary - the declarative extension
+will resolve them at class construction time::
+
+    class MyMixin:
+        @declared_attr
+        def type_(cls):
+            return Column(String(50))
+
+        __mapper_args__= {'polymorphic_on':type_}
+
+    class MyModel(MyMixin, Base):
+        __tablename__='test'
+        id =  Column(Integer, primary_key=True)
+
+
+
+Mixing in Relationships
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Relationships created by :func:`~sqlalchemy.orm.relationship` are provided
+with declarative mixin classes exclusively using the
+:class:`.declared_attr` approach, eliminating any ambiguity
+which could arise when copying a relationship and its possibly column-bound
+contents. Below is an example which combines a foreign key column and a
+relationship so that two classes ``Foo`` and ``Bar`` can both be configured to
+reference a common target class via many-to-one::
+
+    class RefTargetMixin(object):
+        @declared_attr
+        def target_id(cls):
+            return Column('target_id', ForeignKey('target.id'))
+
+        @declared_attr
+        def target(cls):
+            return relationship("Target")
+
+    class Foo(RefTargetMixin, Base):
+        __tablename__ = 'foo'
+        id = Column(Integer, primary_key=True)
+
+    class Bar(RefTargetMixin, Base):
+        __tablename__ = 'bar'
+        id = Column(Integer, primary_key=True)
+
+    class Target(Base):
+        __tablename__ = 'target'
+        id = Column(Integer, primary_key=True)
+
+Using Advanced Relationship Arguments (e.g. ``primaryjoin``, etc.)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+:func:`~sqlalchemy.orm.relationship` definitions which require explicit
+primaryjoin, order_by etc. expressions should in all but the most
+simplistic cases use **late bound** forms
+for these arguments, meaning, using either the string form or a lambda.
+The reason for this is that the related :class:`.Column` objects which are to
+be configured using ``@declared_attr`` are not available to another
+``@declared_attr`` attribute; while the methods will work and return new
+:class:`.Column` objects, those are not the :class:`.Column` objects that
+Declarative will be using as it calls the methods on its own, thus using
+*different* :class:`.Column` objects.
+
+The canonical example is the primaryjoin condition that depends upon
+another mixed-in column::
+
+    class RefTargetMixin(object):
+        @declared_attr
+        def target_id(cls):
+            return Column('target_id', ForeignKey('target.id'))
+
+        @declared_attr
+        def target(cls):
+            return relationship(Target,
+                primaryjoin=Target.id==cls.target_id   # this is *incorrect*
+            )
+
+Mapping a class using the above mixin, we will get an error like::
+
+    sqlalchemy.exc.InvalidRequestError: this ForeignKey's parent column is not
+    yet associated with a Table.
+
+This is because the ``target_id`` :class:`.Column` we've called upon in our
+``target()`` method is not the same :class:`.Column` that declarative is
+actually going to map to our table.
+
+The condition above is resolved using a lambda::
+
+    class RefTargetMixin(object):
+        @declared_attr
+        def target_id(cls):
+            return Column('target_id', ForeignKey('target.id'))
+
+        @declared_attr
+        def target(cls):
+            return relationship(Target,
+                primaryjoin=lambda: Target.id==cls.target_id
+            )
+
+or alternatively, the string form (which ultimately generates a lambda)::
+
+    class RefTargetMixin(object):
+        @declared_attr
+        def target_id(cls):
+            return Column('target_id', ForeignKey('target.id'))
+
+        @declared_attr
+        def target(cls):
+            return relationship("Target",
+                primaryjoin="Target.id==%s.target_id" % cls.__name__
+            )
+
+Mixing in deferred(), column_property(), and other MapperProperty classes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Like :func:`~sqlalchemy.orm.relationship`, all
+:class:`~sqlalchemy.orm.interfaces.MapperProperty` subclasses such as
+:func:`~sqlalchemy.orm.deferred`, :func:`~sqlalchemy.orm.column_property`,
+etc. ultimately involve references to columns, and therefore, when
+used with declarative mixins, have the :class:`.declared_attr`
+requirement so that no reliance on copying is needed::
+
+    class SomethingMixin(object):
+
+        @declared_attr
+        def dprop(cls):
+            return deferred(Column(Integer))
+
+    class Something(SomethingMixin, Base):
+        __tablename__ = "something"
+
+Mixing in Association Proxy and Other Attributes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Mixins can specify user-defined attributes as well as other extension
+units such as :func:`.association_proxy`.   The usage of
+:class:`.declared_attr` is required in those cases where the attribute must
+be tailored specifically to the target subclass.   An example is when
+constructing multiple :func:`.association_proxy` attributes which each
+target a different type of child object.  Below is an
+:func:`.association_proxy` / mixin example which provides a scalar list of
+string values to an implementing class::
+
+    from sqlalchemy import Column, Integer, ForeignKey, String
+    from sqlalchemy.orm import relationship
+    from sqlalchemy.ext.associationproxy import association_proxy
+    from sqlalchemy.ext.declarative import declarative_base, declared_attr
+
+    Base = declarative_base()
+
+    class HasStringCollection(object):
+        @declared_attr
+        def _strings(cls):
+            class StringAttribute(Base):
+                __tablename__ = cls.string_table_name
+                id = Column(Integer, primary_key=True)
+                value = Column(String(50), nullable=False)
+                parent_id = Column(Integer,
+                                ForeignKey('%s.id' % cls.__tablename__),
+                                nullable=False)
+                def __init__(self, value):
+                    self.value = value
+
+            return relationship(StringAttribute)
+
+        @declared_attr
+        def strings(cls):
+            return association_proxy('_strings', 'value')
+
+    class TypeA(HasStringCollection, Base):
+        __tablename__ = 'type_a'
+        string_table_name = 'type_a_strings'
+        id = Column(Integer(), primary_key=True)
+
+    class TypeB(HasStringCollection, Base):
+        __tablename__ = 'type_b'
+        string_table_name = 'type_b_strings'
+        id = Column(Integer(), primary_key=True)
+
+Above, the ``HasStringCollection`` mixin produces a :func:`.relationship`
+which refers to a newly generated class called ``StringAttribute``.  The
+``StringAttribute`` class is generated with its own :class:`.Table`
+definition which is local to the parent class making usage of the
+``HasStringCollection`` mixin.  It also produces an :func:`.association_proxy`
+object which proxies references to the ``strings`` attribute onto the ``value``
+attribute of each ``StringAttribute`` instance.
+
+``TypeA`` or ``TypeB`` can be instantiated given the constructor
+argument ``strings``, a list of strings::
+
+    ta = TypeA(strings=['foo', 'bar'])
+    tb = TypeA(strings=['bat', 'bar'])
+
+This list will generate a collection
+of ``StringAttribute`` objects, which are persisted into a table that's
+local to either the ``type_a_strings`` or ``type_b_strings`` table::
+
+    >>> print ta._strings
+    [<__main__.StringAttribute object at 0x10151cd90>,
+        <__main__.StringAttribute object at 0x10151ce10>]
+
+When constructing the :func:`.association_proxy`, the
+:class:`.declared_attr` decorator must be used so that a distinct
+:func:`.association_proxy` object is created for each of the ``TypeA``
+and ``TypeB`` classes.
+
+.. versionadded:: 0.8 :class:`.declared_attr` is usable with non-mapped
+   attributes, including user-defined attributes as well as
+   :func:`.association_proxy`.
+
+
+Controlling table inheritance with mixins
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``__tablename__`` attribute in conjunction with the hierarchy of
+classes involved in a declarative mixin scenario controls what type of
+table inheritance, if any,
+is configured by the declarative extension.
+
+If the ``__tablename__`` is computed by a mixin, you may need to
+control which classes get the computed attribute in order to get the
+type of table inheritance you require.
+
+For example, if you had a mixin that computes ``__tablename__`` but
+where you wanted to use that mixin in a single table inheritance
+hierarchy, you can explicitly specify ``__tablename__`` as ``None`` to
+indicate that the class should not have a table mapped::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class Tablename:
+        @declared_attr
+        def __tablename__(cls):
+            return cls.__name__.lower()
+
+    class Person(Tablename, Base):
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        __tablename__ = None
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+        primary_language = Column(String(50))
+
+Alternatively, you can make the mixin intelligent enough to only
+return a ``__tablename__`` in the event that no table is already
+mapped in the inheritance hierarchy. To help with this, a
+:func:`~sqlalchemy.ext.declarative.has_inherited_table` helper
+function is provided that returns ``True`` if a parent class already
+has a mapped table.
+
+As an example, here's a mixin that will only allow single table
+inheritance::
+
+    from sqlalchemy.ext.declarative import declared_attr
+    from sqlalchemy.ext.declarative import has_inherited_table
+
+    class Tablename(object):
+        @declared_attr
+        def __tablename__(cls):
+            if has_inherited_table(cls):
+                return None
+            return cls.__name__.lower()
+
+    class Person(Tablename, Base):
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}

+
+
+Combining Table/Mapper Arguments from Multiple Mixins
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In the case of ``__table_args__`` or ``__mapper_args__``
+specified with declarative mixins, you may want to combine
+some parameters from several mixins with those you wish to
+define on the class iteself. The
+:class:`.declared_attr` decorator can be used
+here to create user-defined collation routines that pull
+from multiple collections::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class MySQLSettings(object):
+        __table_args__ = {'mysql_engine':'InnoDB'}
+
+    class MyOtherMixin(object):
+        __table_args__ = {'info':'foo'}
+
+    class MyModel(MySQLSettings, MyOtherMixin, Base):
+        __tablename__='my_model'
+
+        @declared_attr
+        def __table_args__(cls):
+            args = dict()
+            args.update(MySQLSettings.__table_args__)
+            args.update(MyOtherMixin.__table_args__)
+            return args
+
+        id =  Column(Integer, primary_key=True)
+
+Creating Indexes with Mixins
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To define a named, potentially multicolumn :class:`.Index` that applies to all
+tables derived from a mixin, use the "inline" form of :class:`.Index` and
+establish it as part of ``__table_args__``::
+
+    class MyMixin(object):
+        a =  Column(Integer)
+        b =  Column(Integer)
+
+        @declared_attr
+        def __table_args__(cls):
+            return (Index('test_idx_%s' % cls.__tablename__, 'a', 'b'),)
+
+    class MyModel(MyMixin, Base):
+        __tablename__ = 'atable'
+        c =  Column(Integer,primary_key=True)
+
+Special Directives
+==================
+
+``__declare_last__()``
+~~~~~~~~~~~~~~~~~~~~~~
+
+The ``__declare_last__()`` hook allows definition of
+a class level function that is automatically called by the
+:meth:`.MapperEvents.after_configured` event, which occurs after mappings are
+assumed to be completed and the 'configure' step has finished::
+
+    class MyClass(Base):
+        @classmethod
+        def __declare_last__(cls):
+            ""
+            # do something with mappings
+
+.. versionadded:: 0.7.3
+
+``__declare_first__()``
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Like ``__declare_last__()``, but is called at the beginning of mapper
+configuration via the :meth:`.MapperEvents.before_configured` event::
+
+    class MyClass(Base):
+        @classmethod
+        def __declare_first__(cls):
+            ""
+            # do something before mappings are configured
+
+.. versionadded:: 0.9.3
+
+.. _declarative_abstract:
+
+``__abstract__``
+~~~~~~~~~~~~~~~~~~~
+
+``__abstract__`` causes declarative to skip the production
+of a table or mapper for the class entirely.  A class can be added within a
+hierarchy in the same way as mixin (see :ref:`declarative_mixins`), allowing
+subclasses to extend just from the special class::
+
+    class SomeAbstractBase(Base):
+        __abstract__ = True
+
+        def some_helpful_method(self):
+            ""
+
+        @declared_attr
+        def __mapper_args__(cls):
+            return {"helpful mapper arguments":True}
+
+    class MyMappedClass(SomeAbstractBase):
+        ""
+
+One possible use of ``__abstract__`` is to use a distinct
+:class:`.MetaData` for different bases::
+
+    Base = declarative_base()
+
+    class DefaultBase(Base):
+        __abstract__ = True
+        metadata = MetaData()
+
+    class OtherBase(Base):
+        __abstract__ = True
+        metadata = MetaData()
+
+Above, classes which inherit from ``DefaultBase`` will use one
+:class:`.MetaData` as the registry of tables, and those which inherit from
+``OtherBase`` will use a different one. The tables themselves can then be
+created perhaps within distinct databases::
+
+    DefaultBase.metadata.create_all(some_engine)
+    OtherBase.metadata_create_all(some_other_engine)
+
+.. versionadded:: 0.7.3
+
+Class Constructor
+=================
+
+As a convenience feature, the :func:`declarative_base` sets a default
+constructor on classes which takes keyword arguments, and assigns them
+to the named attributes::
+
+    e = Engineer(primary_language='python')
+
+Sessions
+========
+
+Note that ``declarative`` does nothing special with sessions, and is
+only intended as an easier way to configure mappers and
+:class:`~sqlalchemy.schema.Table` objects.  A typical application
+setup using :class:`~sqlalchemy.orm.scoping.scoped_session` might look like::
+
+    engine = create_engine('postgresql://scott:tiger@localhost/test')
+    Session = scoped_session(sessionmaker(autocommit=False,
+                                          autoflush=False,
+                                          bind=engine))
+    Base = declarative_base()
+
+Mapped instances then make usage of
+:class:`~sqlalchemy.orm.session.Session` in the usual way.

+    setting a :class:`.Table` object using autoload=True
+    as the ``__table__`` attribute on a declarative class.
+    The caveat is that the :class:`.Table` must be fully
+    reflected, or at the very least have a primary key column,
+    at the point at which a normal declarative mapping is
+    constructed, meaning the :class:`.Engine` must be available
+    at class declaration time.
+
+    The :class:`.DeferredReflection` mixin moves the construction
+    of mappers to be at a later point, after a specific
+    method is called which first reflects all :class:`.Table`
+    objects created so far.   Classes can define it as such::
+
+        from sqlalchemy.ext.declarative import declarative_base
+        from sqlalchemy.ext.declarative import DeferredReflection
+        Base = declarative_base()
+
+        class MyClass(DeferredReflection, Base):
+            __tablename__ = 'mytable'
+
+    Above, ``MyClass`` is not yet mapped.   After a series of
+    classes have been defined in the above fashion, all tables
+    can be reflected and mappings created using
+    :meth:`.prepare`::
+
+        engine = create_engine("someengine://...")
+        DeferredReflection.prepare(engine)
+
+    The :class:`.DeferredReflection` mixin can be applied to individual
+    classes, used as the base for the declarative base itself,
+    or used in a custom abstract class.   Using an abstract base
+    allows that only a subset of classes to be prepared for a
+    particular prepare step, which is necessary for applications
+    that use more than one engine.  For example, if an application
+    has two engines, you might use two bases, and prepare each
+    separately, e.g.::
+
+        class ReflectedOne(DeferredReflection, Base):
+            __abstract__ = True
+
+        class ReflectedTwo(DeferredReflection, Base):
+            __abstract__ = True
+
+        class MyClass(ReflectedOne):
+            __tablename__ = 'mytable'
+
+        class MyOtherClass(ReflectedOne):
+            __tablename__ = 'myothertable'
+
+        class YetAnotherClass(ReflectedTwo):
+            __tablename__ = 'yetanothertable'
+
+        # ... etc.
+
+    Above, the class hierarchies for ``ReflectedOne`` and
+    ``ReflectedTwo`` can be configured separately::
+
+        ReflectedOne.prepare(engine_one)
+        ReflectedTwo.prepare(engine_two)
+
+    .. versionadded:: 0.8

+"""Define attributes on ORM-mapped classes that have "hybrid" behavior.
+
+"hybrid" means the attribute has distinct behaviors defined at the
+class level and at the instance level.
+
+The :mod:`~sqlalchemy.ext.hybrid` extension provides a special form of
+method decorator, is around 50 lines of code and has almost no
+dependencies on the rest of SQLAlchemy.  It can, in theory, work with
+any descriptor-based expression system.
+
+Consider a mapping ``Interval``, representing integer ``start`` and ``end``
+values. We can define higher level functions on mapped classes that produce
+SQL expressions at the class level, and Python expression evaluation at the
+instance level.  Below, each function decorated with :class:`.hybrid_method` or
+:class:`.hybrid_property` may receive ``self`` as an instance of the class, or
+as the class itself::
+
+    from sqlalchemy import Column, Integer
+    from sqlalchemy.ext.declarative import declarative_base
+    from sqlalchemy.orm import Session, aliased
+    from sqlalchemy.ext.hybrid import hybrid_property, hybrid_method
+
+    Base = declarative_base()
+
+    class Interval(Base):
+        __tablename__ = 'interval'
+
+        id = Column(Integer, primary_key=True)
+        start = Column(Integer, nullable=False)
+        end = Column(Integer, nullable=False)
+
+        def __init__(self, start, end):
+            self.start = start
+            self.end = end
+
+        @hybrid_property
+        def length(self):
+            return self.end - self.start
+
+        @hybrid_method
+        def contains(self,point):
+            return (self.start <= point) & (point < self.end)
+
+        @hybrid_method
+        def intersects(self, other):
+            return self.contains(other.start) | self.contains(other.end)
+
+Above, the ``length`` property returns the difference between the
+``end`` and ``start`` attributes.  With an instance of ``Interval``,
+this subtraction occurs in Python, using normal Python descriptor
+mechanics::
+
+    >>> i1 = Interval(5, 10)
+    >>> i1.length
+    5
+
+When dealing with the ``Interval`` class itself, the :class:`.hybrid_property`
+descriptor evaluates the function body given the ``Interval`` class as
+the argument, which when evaluated with SQLAlchemy expression mechanics
+returns a new SQL expression::
+
+    >>> print Interval.length
+    interval."end" - interval.start
+
+    >>> print Session().query(Interval).filter(Interval.length > 10)
+    SELECT interval.id AS interval_id, interval.start AS interval_start,
+    interval."end" AS interval_end
+    FROM interval
+    WHERE interval."end" - interval.start > :param_1
+
+ORM methods such as :meth:`~.Query.filter_by` generally use ``getattr()`` to
+locate attributes, so can also be used with hybrid attributes::
+
+    >>> print Session().query(Interval).filter_by(length=5)
+    SELECT interval.id AS interval_id, interval.start AS interval_start,
+    interval."end" AS interval_end
+    FROM interval
+    WHERE interval."end" - interval.start = :param_1
+
+The ``Interval`` class example also illustrates two methods,
+``contains()`` and ``intersects()``, decorated with
+:class:`.hybrid_method`. This decorator applies the same idea to
+methods that :class:`.hybrid_property` applies to attributes.   The
+methods return boolean values, and take advantage of the Python ``|``
+and ``&`` bitwise operators to produce equivalent instance-level and
+SQL expression-level boolean behavior::
+
+    >>> i1.contains(6)
+    True
+    >>> i1.contains(15)
+    False
+    >>> i1.intersects(Interval(7, 18))
+    True
+    >>> i1.intersects(Interval(25, 29))
+    False
+
+    >>> print Session().query(Interval).filter(Interval.contains(15))
+    SELECT interval.id AS interval_id, interval.start AS interval_start,
+    interval."end" AS interval_end
+    FROM interval
+    WHERE interval.start <= :start_1 AND interval."end" > :end_1
+
+    >>> ia = aliased(Interval)
+    >>> print Session().query(Interval, ia).filter(Interval.intersects(ia))
+    SELECT interval.id AS interval_id, interval.start AS interval_start,
+    interval."end" AS interval_end, interval_1.id AS interval_1_id,
+    interval_1.start AS interval_1_start, interval_1."end" AS interval_1_end
+    FROM interval, interval AS interval_1
+    WHERE interval.start <= interval_1.start
+        AND interval."end" > interval_1.start
+        OR interval.start <= interval_1."end"
+        AND interval."end" > interval_1."end"
+
+Defining Expression Behavior Distinct from Attribute Behavior
+--------------------------------------------------------------
+
+Our usage of the ``&`` and ``|`` bitwise operators above was
+fortunate, considering our functions operated on two boolean values to
+return a new one.   In many cases, the construction of an in-Python
+function and a SQLAlchemy SQL expression have enough differences that
+two separate Python expressions should be defined.  The
+:mod:`~sqlalchemy.ext.hybrid` decorators define the
+:meth:`.hybrid_property.expression` modifier for this purpose.   As an
+example we'll define the radius of the interval, which requires the
+usage of the absolute value function::
+
+    from sqlalchemy import func
+
+    class Interval(object):
+        # ...
+
+        @hybrid_property
+        def radius(self):
+            return abs(self.length) / 2
+
+        @radius.expression
+        def radius(cls):
+            return func.abs(cls.length) / 2
+
+Above the Python function ``abs()`` is used for instance-level
+operations, the SQL function ``ABS()`` is used via the :attr:`.func`
+object for class-level expressions::
+
+    >>> i1.radius
+    2
+
+    >>> print Session().query(Interval).filter(Interval.radius > 5)
+    SELECT interval.id AS interval_id, interval.start AS interval_start,
+        interval."end" AS interval_end
+    FROM interval
+    WHERE abs(interval."end" - interval.start) / :abs_1 > :param_1
+
+Defining Setters
+----------------
+
+Hybrid properties can also define setter methods.  If we wanted
+``length`` above, when set, to modify the endpoint value::
+
+    class Interval(object):
+        # ...
+
+        @hybrid_property
+        def length(self):
+            return self.end - self.start
+
+        @length.setter
+        def length(self, value):
+            self.end = self.start + value
+
+The ``length(self, value)`` method is now called upon set::
+
+    >>> i1 = Interval(5, 10)
+    >>> i1.length
+    5
+    >>> i1.length = 12
+    >>> i1.end
+    17
+
+Working with Relationships
+--------------------------
+
+There's no essential difference when creating hybrids that work with
+related objects as opposed to column-based data. The need for distinct
+expressions tends to be greater.  Two variants of we'll illustrate
+are the "join-dependent" hybrid, and the "correlated subquery" hybrid.
+
+Join-Dependent Relationship Hybrid
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Consider the following declarative
+mapping which relates a ``User`` to a ``SavingsAccount``::
+
+    from sqlalchemy import Column, Integer, ForeignKey, Numeric, String
+    from sqlalchemy.orm import relationship
+    from sqlalchemy.ext.declarative import declarative_base
+    from sqlalchemy.ext.hybrid import hybrid_property
+
+    Base = declarative_base()
+
+    class SavingsAccount(Base):
+        __tablename__ = 'account'
+        id = Column(Integer, primary_key=True)
+        user_id = Column(Integer, ForeignKey('user.id'), nullable=False)
+        balance = Column(Numeric(15, 5))
+
+    class User(Base):
+        __tablename__ = 'user'
+        id = Column(Integer, primary_key=True)
+        name = Column(String(100), nullable=False)
+
+        accounts = relationship("SavingsAccount", backref="owner")
+
+        @hybrid_property
+        def balance(self):
+            if self.accounts:
+                return self.accounts[0].balance
+            else:
+                return None
+
+        @balance.setter
+        def balance(self, value):
+            if not self.accounts:
+                account = Account(owner=self)
+            else:
+                account = self.accounts[0]
+            account.balance = value
+
+        @balance.expression
+        def balance(cls):
+            return SavingsAccount.balance
+
+The above hybrid property ``balance`` works with the first
+``SavingsAccount`` entry in the list of accounts for this user.   The
+in-Python getter/setter methods can treat ``accounts`` as a Python
+list available on ``self``.
+
+However, at the expression level, it's expected that the ``User`` class will
+be used in an appropriate context such that an appropriate join to
+``SavingsAccount`` will be present::
+
+    >>> print Session().query(User, User.balance).\\
+    ...     join(User.accounts).filter(User.balance > 5000)
+    SELECT "user".id AS user_id, "user".name AS user_name,
+    account.balance AS account_balance
+    FROM "user" JOIN account ON "user".id = account.user_id
+    WHERE account.balance > :balance_1
+
+Note however, that while the instance level accessors need to worry
+about whether ``self.accounts`` is even present, this issue expresses
+itself differently at the SQL expression level, where we basically
+would use an outer join::
+
+    >>> from sqlalchemy import or_
+    >>> print (Session().query(User, User.balance).outerjoin(User.accounts).
+    ...         filter(or_(User.balance < 5000, User.balance == None)))
+    SELECT "user".id AS user_id, "user".name AS user_name,
+    account.balance AS account_balance
+    FROM "user" LEFT OUTER JOIN account ON "user".id = account.user_id
+    WHERE account.balance <  :balance_1 OR account.balance IS NULL
+
+Correlated Subquery Relationship Hybrid
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+We can, of course, forego being dependent on the enclosing query's usage
+of joins in favor of the correlated subquery, which can portably be packed
+into a single column expression. A correlated subquery is more portable, but
+often performs more poorly at the SQL level. Using the same technique
+illustrated at :ref:`mapper_column_property_sql_expressions`,
+we can adjust our ``SavingsAccount`` example to aggregate the balances for
+*all* accounts, and use a correlated subquery for the column expression::
+
+    from sqlalchemy import Column, Integer, ForeignKey, Numeric, String
+    from sqlalchemy.orm import relationship
+    from sqlalchemy.ext.declarative import declarative_base
+    from sqlalchemy.ext.hybrid import hybrid_property
+    from sqlalchemy import select, func
+
+    Base = declarative_base()
+

+        user_id = Column(Integer, ForeignKey('user.id'), nullable=False)
+        balance = Column(Numeric(15, 5))
+
+    class User(Base):
+        __tablename__ = 'user'
+        id = Column(Integer, primary_key=True)
+        name = Column(String(100), nullable=False)
+

+            return sum(acc.balance for acc in self.accounts)

+                    where(SavingsAccount.user_id==cls.id).\\
+                    label('total_balance')
+
+The above recipe will give us the ``balance`` column which renders
+a correlated SELECT::
+
+    >>> print s.query(User).filter(User.balance > 400)
+    SELECT "user".id AS user_id, "user".name AS user_name
+    FROM "user"
+    WHERE (SELECT sum(account.balance) AS sum_1
+    FROM account
+    WHERE account.user_id = "user".id) > :param_1
+
+.. _hybrid_custom_comparators:
+
+Building Custom Comparators
+---------------------------
+
+The hybrid property also includes a helper that allows construction of
+custom comparators. A comparator object allows one to customize the
+behavior of each SQLAlchemy expression operator individually.  They
+are useful when creating custom types that have some highly
+idiosyncratic behavior on the SQL side.
+
+The example class below allows case-insensitive comparisons on the attribute
+named ``word_insensitive``::
+
+    from sqlalchemy.ext.hybrid import Comparator, hybrid_property
+    from sqlalchemy import func, Column, Integer, String
+    from sqlalchemy.orm import Session
+    from sqlalchemy.ext.declarative import declarative_base
+
+    Base = declarative_base()
+
+    class CaseInsensitiveComparator(Comparator):
+        def __eq__(self, other):
+            return func.lower(self.__clause_element__()) == func.lower(other)
+
+    class SearchWord(Base):
+        __tablename__ = 'searchword'
+        id = Column(Integer, primary_key=True)
+        word = Column(String(255), nullable=False)
+
+        @hybrid_property
+        def word_insensitive(self):
+            return self.word.lower()
+
+        @word_insensitive.comparator
+        def word_insensitive(cls):
+            return CaseInsensitiveComparator(cls.word)
+
+Above, SQL expressions against ``word_insensitive`` will apply the ``LOWER()``
+SQL function to both sides::
+
+    >>> print Session().query(SearchWord).filter_by(word_insensitive="Trucks")
+    SELECT searchword.id AS searchword_id, searchword.word AS searchword_word
+    FROM searchword
+    WHERE lower(searchword.word) = lower(:lower_1)
+
+The ``CaseInsensitiveComparator`` above implements part of the
+:class:`.ColumnOperators` interface.   A "coercion" operation like
+lowercasing can be applied to all comparison operations (i.e. ``eq``,
+``lt``, ``gt``, etc.) using :meth:`.Operators.operate`::
+
+    class CaseInsensitiveComparator(Comparator):
+        def operate(self, op, other):
+            return op(func.lower(self.__clause_element__()), func.lower(other))
+
+Hybrid Value Objects
+--------------------
+
+Note in our previous example, if we were to compare the
+``word_insensitive`` attribute of a ``SearchWord`` instance to a plain
+Python string, the plain Python string would not be coerced to lower
+case - the ``CaseInsensitiveComparator`` we built, being returned by
+``@word_insensitive.comparator``, only applies to the SQL side.
+
+A more comprehensive form of the custom comparator is to construct a
+*Hybrid Value Object*. This technique applies the target value or
+expression to a value object which is then returned by the accessor in
+all cases.   The value object allows control of all operations upon
+the value as well as how compared values are treated, both on the SQL
+expression side as well as the Python value side.   Replacing the
+previous ``CaseInsensitiveComparator`` class with a new
+``CaseInsensitiveWord`` class::
+
+    class CaseInsensitiveWord(Comparator):
+        "Hybrid value representing a lower case representation of a word."
+
+        def __init__(self, word):
+            if isinstance(word, basestring):
+                self.word = word.lower()
+            elif isinstance(word, CaseInsensitiveWord):
+                self.word = word.word
+            else:
+                self.word = func.lower(word)
+
+        def operate(self, op, other):
+            if not isinstance(other, CaseInsensitiveWord):
+                other = CaseInsensitiveWord(other)
+            return op(self.word, other.word)
+
+        def __clause_element__(self):
+            return self.word
+
+        def __str__(self):
+            return self.word
+
+        key = 'word'
+        "Label to apply to Query tuple results"
+
+Above, the ``CaseInsensitiveWord`` object represents ``self.word``,
+which may be a SQL function, or may be a Python native.   By
+overriding ``operate()`` and ``__clause_element__()`` to work in terms
+of ``self.word``, all comparison operations will work against the
+"converted" form of ``word``, whether it be SQL side or Python side.
+Our ``SearchWord`` class can now deliver the ``CaseInsensitiveWord``
+object unconditionally from a single hybrid call::
+
+    class SearchWord(Base):
+        __tablename__ = 'searchword'
+        id = Column(Integer, primary_key=True)
+        word = Column(String(255), nullable=False)
+
+        @hybrid_property
+        def word_insensitive(self):
+            return CaseInsensitiveWord(self.word)
+
+The ``word_insensitive`` attribute now has case-insensitive comparison
+behavior universally, including SQL expression vs. Python expression
+(note the Python value is converted to lower case on the Python side
+here)::
+
+    >>> print Session().query(SearchWord).filter_by(word_insensitive="Trucks")
+    SELECT searchword.id AS searchword_id, searchword.word AS searchword_word
+    FROM searchword
+    WHERE lower(searchword.word) = :lower_1
+
+SQL expression versus SQL expression::
+
+    >>> sw1 = aliased(SearchWord)
+    >>> sw2 = aliased(SearchWord)
+    >>> print Session().query(
+    ...                    sw1.word_insensitive,
+    ...                    sw2.word_insensitive).\\
+    ...                        filter(
+    ...                            sw1.word_insensitive > sw2.word_insensitive
+    ...                        )
+    SELECT lower(searchword_1.word) AS lower_1,
+    lower(searchword_2.word) AS lower_2
+    FROM searchword AS searchword_1, searchword AS searchword_2
+    WHERE lower(searchword_1.word) > lower(searchword_2.word)
+
+Python only expression::
+
+    >>> ws1 = SearchWord(word="SomeWord")
+    >>> ws1.word_insensitive == "sOmEwOrD"
+    True
+    >>> ws1.word_insensitive == "XOmEwOrX"
+    False
+    >>> print ws1.word_insensitive
+    someword
+
+The Hybrid Value pattern is very useful for any kind of value that may
+have multiple representations, such as timestamps, time deltas, units
+of measurement, currencies and encrypted passwords.

+.. _hybrid_transformers:
+
+Building Transformers
+----------------------
+
+A *transformer* is an object which can receive a :class:`.Query`
+object and return a new one.   The :class:`.Query` object includes a
+method :meth:`.with_transformation` that returns a new :class:`.Query`
+transformed by the given function.
+
+We can combine this with the :class:`.Comparator` class to produce one type
+of recipe which can both set up the FROM clause of a query as well as assign
+filtering criterion.
+
+Consider a mapped class ``Node``, which assembles using adjacency list
+into a hierarchical tree pattern::
+
+    from sqlalchemy import Column, Integer, ForeignKey
+    from sqlalchemy.orm import relationship
+    from sqlalchemy.ext.declarative import declarative_base
+    Base = declarative_base()
+
+    class Node(Base):
+        __tablename__ = 'node'
+        id =Column(Integer, primary_key=True)
+        parent_id = Column(Integer, ForeignKey('node.id'))
+        parent = relationship("Node", remote_side=id)
+
+Suppose we wanted to add an accessor ``grandparent``.  This would
+return the ``parent`` of ``Node.parent``.  When we have an instance of
+``Node``, this is simple::
+
+    from sqlalchemy.ext.hybrid import hybrid_property
+
+    class Node(Base):
+        # ...
+
+        @hybrid_property
+        def grandparent(self):
+            return self.parent.parent
+
+For the expression, things are not so clear.   We'd need to construct
+a :class:`.Query` where we :meth:`~.Query.join` twice along
+``Node.parent`` to get to the ``grandparent``.   We can instead return
+a transforming callable that we'll combine with the
+:class:`.Comparator` class to receive any :class:`.Query` object, and
+return a new one that's joined to the ``Node.parent`` attribute and
+filtered based on the given criterion::
+
+    from sqlalchemy.ext.hybrid import Comparator
+
+    class GrandparentTransformer(Comparator):
+        def operate(self, op, other):
+            def transform(q):
+                cls = self.__clause_element__()
+                parent_alias = aliased(cls)
+                return q.join(parent_alias, cls.parent).\\
+                            filter(op(parent_alias.parent, other))
+            return transform
+
+    Base = declarative_base()
+
+    class Node(Base):
+        __tablename__ = 'node'
+        id =Column(Integer, primary_key=True)
+        parent_id = Column(Integer, ForeignKey('node.id'))
+        parent = relationship("Node", remote_side=id)
+
+        @hybrid_property
+        def grandparent(self):
+            return self.parent.parent
+
+        @grandparent.comparator
+        def grandparent(cls):
+            return GrandparentTransformer(cls)
+
+The ``GrandparentTransformer`` overrides the core
+:meth:`.Operators.operate` method at the base of the
+:class:`.Comparator` hierarchy to return a query-transforming
+callable, which then runs the given comparison operation in a
+particular context. Such as, in the example above, the ``operate``
+method is called, given the :attr:`.Operators.eq` callable as well as
+the right side of the comparison ``Node(id=5)``.  A function
+``transform`` is then returned which will transform a :class:`.Query`
+first to join to ``Node.parent``, then to compare ``parent_alias``
+using :attr:`.Operators.eq` against the left and right sides, passing
+into :class:`.Query.filter`:
+
+.. sourcecode:: pycon+sql
+
+    >>> from sqlalchemy.orm import Session
+    >>> session = Session()
+    {sql}>>> session.query(Node).\\
+    ...        with_transformation(Node.grandparent==Node(id=5)).\\
+    ...        all()
+    SELECT node.id AS node_id, node.parent_id AS node_parent_id
+    FROM node JOIN node AS node_1 ON node_1.id = node.parent_id
+    WHERE :param_1 = node_1.parent_id
+    {stop}
+
+We can modify the pattern to be more verbose but flexible by separating
+the "join" step from the "filter" step.  The tricky part here is ensuring
+that successive instances of ``GrandparentTransformer`` use the same
+:class:`.AliasedClass` object against ``Node``.  Below we use a simple
+memoizing approach that associates a ``GrandparentTransformer``
+with each class::
+
+    class Node(Base):
+
+        # ...
+
+        @grandparent.comparator
+        def grandparent(cls):
+            # memoize a GrandparentTransformer
+            # per class
+            if '_gp' not in cls.__dict__:
+                cls._gp = GrandparentTransformer(cls)
+            return cls._gp
+
+    class GrandparentTransformer(Comparator):
+
+        def __init__(self, cls):
+            self.parent_alias = aliased(cls)
+
+        @property
+        def join(self):
+            def go(q):
+                return q.join(self.parent_alias, Node.parent)
+            return go
+
+        def operate(self, op, other):
+            return op(self.parent_alias.parent, other)
+
+.. sourcecode:: pycon+sql
+
+    {sql}>>> session.query(Node).\\
+    ...            with_transformation(Node.grandparent.join).\\
+    ...            filter(Node.grandparent==Node(id=5))
+    SELECT node.id AS node_id, node.parent_id AS node_parent_id
+    FROM node JOIN node AS node_1 ON node_1.id = node.parent_id
+    WHERE :param_1 = node_1.parent_id
+    {stop}
+
+The "transformer" pattern is an experimental pattern that starts
+to make usage of some functional programming paradigms.
+While it's only recommended for advanced and/or patient developers,
+there's probably a whole lot of amazing things it can be used for.

+

+
+Establishing Mutability on Scalar Column Values
+===============================================
+
+A typical example of a "mutable" structure is a Python dictionary.
+Following the example introduced in :ref:`types_toplevel`, we
+begin with a custom type that marshals Python dictionaries into
+JSON strings before being persisted::
+
+    from sqlalchemy.types import TypeDecorator, VARCHAR
+    import json
+
+    class JSONEncodedDict(TypeDecorator):
+        "Represents an immutable structure as a json-encoded string."
+
+        impl = VARCHAR
+
+        def process_bind_param(self, value, dialect):
+            if value is not None:
+                value = json.dumps(value)
+            return value
+
+        def process_result_value(self, value, dialect):
+            if value is not None:
+                value = json.loads(value)
+            return value
+
+The usage of ``json`` is only for the purposes of example. The
+:mod:`sqlalchemy.ext.mutable` extension can be used
+with any type whose target Python type may be mutable, including
+:class:`.PickleType`, :class:`.postgresql.ARRAY`, etc.
+
+When using the :mod:`sqlalchemy.ext.mutable` extension, the value itself
+tracks all parents which reference it.  Below, we illustrate the a simple
+version of the :class:`.MutableDict` dictionary object, which applies
+the :class:`.Mutable` mixin to a plain Python dictionary::
+
+    from sqlalchemy.ext.mutable import Mutable
+
+    class MutableDict(Mutable, dict):
+        @classmethod
+        def coerce(cls, key, value):
+            "Convert plain dictionaries to MutableDict."
+
+            if not isinstance(value, MutableDict):
+                if isinstance(value, dict):
+                    return MutableDict(value)
+
+                # this call will raise ValueError
+                return Mutable.coerce(key, value)
+            else:
+                return value
+
+        def __setitem__(self, key, value):
+            "Detect dictionary set events and emit change events."
+
+            dict.__setitem__(self, key, value)
+            self.changed()
+
+        def __delitem__(self, key):
+            "Detect dictionary del events and emit change events."
+
+            dict.__delitem__(self, key)
+            self.changed()
+
+The above dictionary class takes the approach of subclassing the Python
+built-in ``dict`` to produce a dict
+subclass which routes all mutation events through ``__setitem__``.  There are
+variants on this approach, such as subclassing ``UserDict.UserDict`` or
+``collections.MutableMapping``; the part that's important to this example is
+that the :meth:`.Mutable.changed` method is called whenever an in-place
+change to the datastructure takes place.
+
+We also redefine the :meth:`.Mutable.coerce` method which will be used to
+convert any values that are not instances of ``MutableDict``, such
+as the plain dictionaries returned by the ``json`` module, into the
+appropriate type.  Defining this method is optional; we could just as well
+created our ``JSONEncodedDict`` such that it always returns an instance
+of ``MutableDict``, and additionally ensured that all calling code
+uses ``MutableDict`` explicitly.  When :meth:`.Mutable.coerce` is not
+overridden, any values applied to a parent object which are not instances
+of the mutable type will raise a ``ValueError``.
+
+Our new ``MutableDict`` type offers a class method
+:meth:`~.Mutable.as_mutable` which we can use within column metadata
+to associate with types. This method grabs the given type object or
+class and associates a listener that will detect all future mappings
+of this type, applying event listening instrumentation to the mapped
+attribute. Such as, with classical table metadata::
+
+    from sqlalchemy import Table, Column, Integer
+
+    my_data = Table('my_data', metadata,
+        Column('id', Integer, primary_key=True),
+        Column('data', MutableDict.as_mutable(JSONEncodedDict))
+    )
+
+Above, :meth:`~.Mutable.as_mutable` returns an instance of ``JSONEncodedDict``
+(if the type object was not an instance already), which will intercept any
+attributes which are mapped against this type.  Below we establish a simple
+mapping against the ``my_data`` table::
+
+    from sqlalchemy import mapper
+
+    class MyDataClass(object):
+        pass
+
+    # associates mutation listeners with MyDataClass.data
+    mapper(MyDataClass, my_data)
+
+The ``MyDataClass.data`` member will now be notified of in place changes
+to its value.
+
+There's no difference in usage when using declarative::
+
+    from sqlalchemy.ext.declarative import declarative_base
+
+    Base = declarative_base()
+
+    class MyDataClass(Base):
+        __tablename__ = 'my_data'
+        id = Column(Integer, primary_key=True)
+        data = Column(MutableDict.as_mutable(JSONEncodedDict))
+
+Any in-place changes to the ``MyDataClass.data`` member
+will flag the attribute as "dirty" on the parent object::
+
+    >>> from sqlalchemy.orm import Session
+
+    >>> sess = Session()
+    >>> m1 = MyDataClass(data={'value1':'foo'})
+    >>> sess.add(m1)
+    >>> sess.commit()
+
+    >>> m1.data['value1'] = 'bar'
+    >>> assert m1 in sess.dirty
+    True
+
+The ``MutableDict`` can be associated with all future instances
+of ``JSONEncodedDict`` in one step, using
+:meth:`~.Mutable.associate_with`.  This is similar to
+:meth:`~.Mutable.as_mutable` except it will intercept all occurrences
+of ``MutableDict`` in all mappings unconditionally, without
+the need to declare it individually::
+
+    MutableDict.associate_with(JSONEncodedDict)
+
+    class MyDataClass(Base):
+        __tablename__ = 'my_data'
+        id = Column(Integer, primary_key=True)
+        data = Column(JSONEncodedDict)
+
+
+Supporting Pickling
+--------------------
+
+The key to the :mod:`sqlalchemy.ext.mutable` extension relies upon the
+placement of a ``weakref.WeakKeyDictionary`` upon the value object, which
+stores a mapping of parent mapped objects keyed to the attribute name under
+which they are associated with this value. ``WeakKeyDictionary`` objects are
+not picklable, due to the fact that they contain weakrefs and function
+callbacks. In our case, this is a good thing, since if this dictionary were
+picklable, it could lead to an excessively large pickle size for our value
+objects that are pickled by themselves outside of the context of the parent.
+The developer responsibility here is only to provide a ``__getstate__`` method
+that excludes the :meth:`~MutableBase._parents` collection from the pickle
+stream::
+
+    class MyMutableType(Mutable):
+        def __getstate__(self):
+            d = self.__dict__.copy()
+            d.pop('_parents', None)
+            return d
+
+With our dictionary example, we need to return the contents of the dict itself
+(and also restore them on __setstate__)::
+
+    class MutableDict(Mutable, dict):
+        # ....
+
+        def __getstate__(self):
+            return dict(self)
+
+        def __setstate__(self, state):
+            self.update(state)
+
+In the case that our mutable value object is pickled as it is attached to one
+or more parent objects that are also part of the pickle, the :class:`.Mutable`
+mixin will re-establish the :attr:`.Mutable._parents` collection on each value
+object as the owning parents themselves are unpickled.
+
+.. _mutable_composites:
+
+Establishing Mutability on Composites
+=====================================
+
+Composites are a special ORM feature which allow a single scalar attribute to
+be assigned an object value which represents information "composed" from one
+or more columns from the underlying mapped table. The usual example is that of
+a geometric "point", and is introduced in :ref:`mapper_composite`.
+
+.. versionchanged:: 0.7
+    The internals of :func:`.orm.composite` have been
+    greatly simplified and in-place mutation detection is no longer enabled by
+    default; instead, the user-defined value must detect changes on its own and
+    propagate them to all owning parents. The :mod:`sqlalchemy.ext.mutable`
+    extension provides the helper class :class:`.MutableComposite`, which is a
+    slight variant on the :class:`.Mutable` class.
+
+As is the case with :class:`.Mutable`, the user-defined composite class
+subclasses :class:`.MutableComposite` as a mixin, and detects and delivers
+change events to its parents via the :meth:`.MutableComposite.changed` method.
+In the case of a composite class, the detection is usually via the usage of
+Python descriptors (i.e. ``@property``), or alternatively via the special
+Python method ``__setattr__()``. Below we expand upon the ``Point`` class
+introduced in :ref:`mapper_composite` to subclass :class:`.MutableComposite`
+and to also route attribute set events via ``__setattr__`` to the
+:meth:`.MutableComposite.changed` method::
+
+    from sqlalchemy.ext.mutable import MutableComposite
+
+    class Point(MutableComposite):
+        def __init__(self, x, y):
+            self.x = x
+            self.y = y
+
+        def __setattr__(self, key, value):
+            "Intercept set events"
+
+            # set the attribute
+            object.__setattr__(self, key, value)
+
+            # alert all parents to the change
+            self.changed()
+
+        def __composite_values__(self):
+            return self.x, self.y
+
+        def __eq__(self, other):
+            return isinstance(other, Point) and \\
+                other.x == self.x and \\
+                other.y == self.y
+
+        def __ne__(self, other):
+            return not self.__eq__(other)
+
+The :class:`.MutableComposite` class uses a Python metaclass to automatically
+establish listeners for any usage of :func:`.orm.composite` that specifies our
+``Point`` type. Below, when ``Point`` is mapped to the ``Vertex`` class,
+listeners are established which will route change events from ``Point``
+objects to each of the ``Vertex.start`` and ``Vertex.end`` attributes::
+
+    from sqlalchemy.orm import composite, mapper
+    from sqlalchemy import Table, Column
+
+    vertices = Table('vertices', metadata,
+        Column('id', Integer, primary_key=True),
+        Column('x1', Integer),
+        Column('y1', Integer),
+        Column('x2', Integer),
+        Column('y2', Integer),
+        )
+
+    class Vertex(object):
+        pass
+
+    mapper(Vertex, vertices, properties={
+        'start': composite(Point, vertices.c.x1, vertices.c.y1),
+        'end': composite(Point, vertices.c.x2, vertices.c.y2)
+    })
+
+Any in-place changes to the ``Vertex.start`` or ``Vertex.end`` members
+will flag the attribute as "dirty" on the parent object::
+
+    >>> from sqlalchemy.orm import Session
+
+    >>> sess = Session()
+    >>> v1 = Vertex(start=Point(3, 4), end=Point(12, 15))
+    >>> sess.add(v1)
+    >>> sess.commit()
+
+    >>> v1.end.x = 8
+    >>> assert v1 in sess.dirty
+    True
+
+Coercing Mutable Composites
+---------------------------
+
+The :meth:`.MutableBase.coerce` method is also supported on composite types.
+In the case of :class:`.MutableComposite`, the :meth:`.MutableBase.coerce`
+method is only called for attribute set operations, not load operations.
+Overriding the :meth:`.MutableBase.coerce` method is essentially equivalent
+to using a :func:`.validates` validation routine for all attributes which
+make use of the custom composite type::
+
+    class Point(MutableComposite):
+        # other Point methods
+        # ...
+
+        def coerce(cls, key, value):
+            if isinstance(value, tuple):
+                value = Point(*value)
+            elif not isinstance(value, Point):
+                raise ValueError("tuple or Point expected")
+            return value
+
+.. versionadded:: 0.7.10,0.8.0b2
+    Support for the :meth:`.MutableBase.coerce` method in conjunction with
+    objects of type :class:`.MutableComposite`.
+
+Supporting Pickling
+--------------------
+
+As is the case with :class:`.Mutable`, the :class:`.MutableComposite` helper
+class uses a ``weakref.WeakKeyDictionary`` available via the
+:meth:`MutableBase._parents` attribute which isn't picklable. If we need to
+pickle instances of ``Point`` or its owning class ``Vertex``, we at least need
+to define a ``__getstate__`` that doesn't include the ``_parents`` dictionary.
+Below we define both a ``__getstate__`` and a ``__setstate__`` that package up
+the minimal form of our ``Point`` class::
+
+    class Point(MutableComposite):
+        # ...
+
+        def __getstate__(self):
+            return self.x, self.y
+
+        def __setstate__(self, state):
+            self.x, self.y = state
+
+As with :class:`.Mutable`, the :class:`.MutableComposite` augments the
+pickling process of the parent's object-relational state so that the
+:meth:`MutableBase._parents` collection is restored to all ``Point`` objects.

+"""A custom list that manages index/position information for contained
+elements.
+
+:author: Jason Kirtland
+
+``orderinglist`` is a helper for mutable ordered relationships.  It will
+intercept list operations performed on a :func:`.relationship`-managed
+collection and
+automatically synchronize changes in list position onto a target scalar
+attribute.
+
+Example: A ``slide`` table, where each row refers to zero or more entries
+in a related ``bullet`` table.   The bullets within a slide are
+displayed in order based on the value of the ``position`` column in the
+``bullet`` table.   As entries are reordered in memory, the value of the
+``position`` attribute should be updated to reflect the new sort order::
+
+
+    Base = declarative_base()
+
+    class Slide(Base):
+        __tablename__ = 'slide'
+
+        id = Column(Integer, primary_key=True)
+        name = Column(String)
+
+        bullets = relationship("Bullet", order_by="Bullet.position")
+
+    class Bullet(Base):
+        __tablename__ = 'bullet'
+        id = Column(Integer, primary_key=True)
+        slide_id = Column(Integer, ForeignKey('slide.id'))
+        position = Column(Integer)
+        text = Column(String)
+
+The standard relationship mapping will produce a list-like attribute on each
+``Slide`` containing all related ``Bullet`` objects,
+but coping with changes in ordering is not handled automatically.
+When appending a ``Bullet`` into ``Slide.bullets``, the ``Bullet.position``
+attribute will remain unset until manually assigned.   When the ``Bullet``
+is inserted into the middle of the list, the following ``Bullet`` objects
+will also need to be renumbered.
+
+The :class:`.OrderingList` object automates this task, managing the
+``position`` attribute on all ``Bullet`` objects in the collection.  It is
+constructed using the :func:`.ordering_list` factory::
+
+    from sqlalchemy.ext.orderinglist import ordering_list
+
+    Base = declarative_base()
+
+    class Slide(Base):
+        __tablename__ = 'slide'
+
+        id = Column(Integer, primary_key=True)
+        name = Column(String)
+
+        bullets = relationship("Bullet", order_by="Bullet.position",
+                                collection_class=ordering_list('position'))
+
+    class Bullet(Base):
+        __tablename__ = 'bullet'
+        id = Column(Integer, primary_key=True)
+        slide_id = Column(Integer, ForeignKey('slide.id'))
+        position = Column(Integer)
+        text = Column(String)
+
+With the above mapping the ``Bullet.position`` attribute is managed::
+
+    s = Slide()
+    s.bullets.append(Bullet())
+    s.bullets.append(Bullet())
+    s.bullets[1].position
+    >>> 1
+    s.bullets.insert(1, Bullet())
+    s.bullets[2].position
+    >>> 2
+
+The :class:`.OrderingList` construct only works with **changes** to a
+collection, and not the initial load from the database, and requires that the
+list be sorted when loaded.  Therefore, be sure to specify ``order_by`` on the
+:func:`.relationship` against the target ordering attribute, so that the
+ordering is correct when first loaded.
+
+.. warning::
+
+  :class:`.OrderingList` only provides limited functionality when a primary
+  key column or unique column is the target of the sort.  Operations
+  that are unsupported or are problematic include:
+
+    * two entries must trade values.  This is not supported directly in the
+      case of a primary key or unique constraint because it means at least
+      one row would need to be temporarily removed first, or changed to
+      a third, neutral value while the switch occurs.
+
+    * an entry must be deleted in order to make room for a new entry.
+      SQLAlchemy's unit of work performs all INSERTs before DELETEs within a
+      single flush.  In the case of a primary key, it will trade
+      an INSERT/DELETE of the same primary key for an UPDATE statement in order

+"""Serializer/Deserializer objects for usage with SQLAlchemy query structures,
+allowing "contextual" deserialization.
+
+Any SQLAlchemy query structure, either based on sqlalchemy.sql.*
+or sqlalchemy.orm.* can be used.  The mappers, Tables, Columns, Session
+etc. which are referenced by the structure are not persisted in serialized
+form, but are instead re-associated with the query structure
+when it is deserialized.
+
+Usage is nearly the same as that of the standard Python pickle module::
+
+    from sqlalchemy.ext.serializer import loads, dumps
+    metadata = MetaData(bind=some_engine)
+    Session = scoped_session(sessionmaker())
+
+    # ... define mappers
+
+    query = Session.query(MyClass).
+        filter(MyClass.somedata=='foo').order_by(MyClass.sortkey)
+
+    # pickle the query
+    serialized = dumps(query)
+
+    # unpickle.  Pass in metadata + scoped_session
+    query2 = loads(serialized, metadata, Session)
+
+    print query2.all()
+
+Similar restrictions as when using raw pickle apply; mapped classes must be
+themselves be pickleable, meaning they are importable from a module-level
+namespace.
+
+The serializer module is only appropriate for query structures.  It is not
+needed for:
+
+* instances of user-defined classes.   These contain no references to engines,
+  sessions or expression constructs in the typical case and can be serialized
+  directly.
+
+* Table metadata that is to be loaded entirely from the serialized structure
+  (i.e. is not already declared in the application).   Regular
+  pickle.loads()/dumps() can be used to fully dump any ``MetaData`` object,
+  typically one which was reflected from an existing database at some previous
+  point in time.  The serializer module is specifically for the opposite case,
+  where the Table metadata is already present in memory.

+"""The inspection module provides the :func:`.inspect` function,
+which delivers runtime information about a wide variety
+of SQLAlchemy objects, both within the Core as well as the
+ORM.
+
+The :func:`.inspect` function is the entry point to SQLAlchemy's
+public API for viewing the configuration and construction
+of in-memory objects.   Depending on the type of object
+passed to :func:`.inspect`, the return value will either be
+a related object which provides a known interface, or in many
+cases it will return the object itself.
+
+The rationale for :func:`.inspect` is twofold.  One is that
+it replaces the need to be aware of a large variety of "information
+getting" functions in SQLAlchemy, such as :meth:`.Inspector.from_engine`,
+:func:`.orm.attributes.instance_state`, :func:`.orm.class_mapper`,
+and others.    The other is that the return value of :func:`.inspect`
+is guaranteed to obey a documented API, thus allowing third party
+tools which build on top of SQLAlchemy configurations to be constructed

+
+    All of the standard connection :class:`~sqlalchemy.pool.Pool` types can
+    accept event listeners for key connection lifecycle events:
+    creation, pool check-out and check-in.  There are no events fired
+    when a connection closes.
+
+    For any given DB-API connection, there will be one ``connect``
+    event, `n` number of ``checkout`` events, and either `n` or `n - 1`
+    ``checkin`` events.  (If a ``Connection`` is detached from its
+    pool via the ``detach()`` method, it won't be checked back in.)
+
+    These are low-level events for low-level objects: raw Python
+    DB-API connections, without the conveniences of the SQLAlchemy
+    ``Connection`` wrapper, ``Dialect`` services or ``ClauseElement``
+    execution.  If you execute SQL through the connection, explicitly
+    closing all cursors and other resources is recommended.
+
+    Events also receive a ``_ConnectionRecord``, a long-lived internal
+    ``Pool`` object that basically represents a "slot" in the
+    connection pool.  ``_ConnectionRecord`` objects have one public
+    attribute of note: ``info``, a dictionary whose contents are
+    scoped to the lifetime of the DB-API connection managed by the
+    record.  You can use this shared storage area however you like.
+
+    There is no need to subclass ``PoolListener`` to handle events.
+    Any class that implements one or more of these methods can be used
+    as a pool listener.  The ``Pool`` will inspect the methods
+    provided by a listener object and add the listener to one or more
+    internal event queues based on its capabilities.  In terms of
+    efficiency and function call overhead, you're much better off only
+    providing implementations for the hooks you'll be using.

+"""Support for collections of mapped entities.
+
+The collections package supplies the machinery used to inform the ORM of
+collection membership changes.  An instrumentation via decoration approach is
+used, allowing arbitrary types (including built-ins) to be used as entity
+collections without requiring inheritance from a base class.
+
+Instrumentation decoration relays membership change events to the
+:class:`.CollectionAttributeImpl` that is currently managing the collection.
+The decorators observe function call arguments and return values, tracking
+entities entering or leaving the collection.  Two decorator approaches are
+provided.  One is a bundle of generic decorators that map function arguments
+and return values to events::
+
+  from sqlalchemy.orm.collections import collection
+  class MyClass(object):
+      # ...
+
+      @collection.adds(1)
+      def store(self, item):
+          self.data.append(item)
+
+      @collection.removes_return()
+      def pop(self):
+          return self.data.pop()
+
+
+The second approach is a bundle of targeted decorators that wrap appropriate
+append and remove notifiers around the mutation methods present in the
+standard Python ``list``, ``set`` and ``dict`` interfaces.  These could be
+specified in terms of generic decorator recipes, but are instead hand-tooled
+for increased efficiency.  The targeted decorators occasionally implement
+adapter-like behavior, such as mapping bulk-set methods (``extend``,
+``update``, ``__setslice__``, etc.) into the series of atomic mutation events
+that the ORM requires.
+
+The targeted decorators are used internally for automatic instrumentation of
+entity collection classes.  Every collection class goes through a
+transformation process roughly like so:
+
+1. If the class is a built-in, substitute a trivial sub-class
+2. Is this class already instrumented?
+3. Add in generic decorators
+4. Sniff out the collection interface through duck-typing
+5. Add targeted decoration to any undecorated interface method
+
+This process modifies the class at runtime, decorating methods and adding some
+bookkeeping properties.  This isn't possible (or desirable) for built-in
+classes like ``list``, so trivial sub-classes are substituted to hold
+decoration::
+
+  class InstrumentedList(list):
+      pass
+
+Collection classes can be specified in ``relationship(collection_class=)`` as
+types or a function that returns an instance.  Collection classes are
+inspected and instrumented during the mapper compilation phase.  The
+collection_class callable will be executed once to produce a specimen
+instance, and the type of that specimen will be instrumented.  Functions that
+return built-in types like ``lists`` will be adapted to produce instrumented
+instances.
+
+When extending a known type like ``list``, additional decorations are not
+generally not needed.  Odds are, the extension method will delegate to a
+method that's already instrumented.  For example::
+
+  class QueueIsh(list):
+     def push(self, item):
+         self.append(item)
+     def shift(self):
+         return self.pop(0)
+
+There's no need to decorate these methods.  ``append`` and ``pop`` are already
+instrumented as part of the ``list`` interface.  Decorating them would fire
+duplicate events, which should be avoided.
+
+The targeted decoration tries not to rely on other methods in the underlying
+collection class, but some are unavoidable.  Many depend on 'read' methods
+being present to properly instrument a 'write', for example, ``__setitem__``
+needs ``__getitem__``.  "Bulk" methods like ``update`` and ``extend`` may also
+reimplemented in terms of atomic appends and removes, so the ``extend``
+decoration will actually perform many ``append`` operations and not call the
+underlying method at all.
+
+Tight control over bulk operation and the firing of events is also possible by
+implementing the instrumentation internally in your methods.  The basic
+instrumentation package works under the general assumption that collection
+mutation will not raise unusual exceptions.  If you want to closely
+orchestrate append and remove events with exception management, internal
+instrumentation may be the answer.  Within your method,
+``collection_adapter(self)`` will retrieve an object that you can use for
+explicit control over triggering append and remove events.
+
+The owning object and :class:`.CollectionAttributeImpl` are also reachable
+through the adapter, allowing for some very sophisticated behavior.

+    """Base implementation for :class:`.Mapper` event hooks.
+
+    .. note::
+
+       :class:`.MapperExtension` is deprecated.   Please
+       refer to :func:`.event.listen` as well as
+       :class:`.MapperEvents`.
+
+    New extension classes subclass :class:`.MapperExtension` and are specified
+    using the ``extension`` mapper() argument, which is a single
+    :class:`.MapperExtension` or a list of such::
+
+        from sqlalchemy.orm.interfaces import MapperExtension
+
+        class MyExtension(MapperExtension):
+            def before_insert(self, mapper, connection, instance):
+                print "instance %s before insert !" % instance
+
+        m = mapper(User, users_table, extension=MyExtension())
+
+    A single mapper can maintain a chain of ``MapperExtension``
+    objects. When a particular mapping event occurs, the
+    corresponding method on each ``MapperExtension`` is invoked
+    serially, and each method has the ability to halt the chain
+    from proceeding further::
+
+        m = mapper(User, users_table, extension=[ext1, ext2, ext3])
+
+    Each ``MapperExtension`` method returns the symbol
+    EXT_CONTINUE by default.   This symbol generally means "move
+    to the next ``MapperExtension`` for processing".  For methods
+    that return objects like translated rows or new object
+    instances, EXT_CONTINUE means the result of the method
+    should be ignored.   In some cases it's required for a
+    default mapper activity to be performed, such as adding a
+    new instance to a result list.
+
+    The symbol EXT_STOP has significance within a chain
+    of ``MapperExtension`` objects that the chain will be stopped
+    when this symbol is returned.  Like EXT_CONTINUE, it also
+    has additional significance in some cases that a default
+    mapper activity will not be performed.

+"""Defines SQLAlchemy's system of class instrumentation.
+
+This module is usually not directly visible to user applications, but
+defines a large part of the ORM's interactivity.
+
+instrumentation.py deals with registration of end-user classes
+for state tracking.   It interacts closely with state.py
+and attributes.py which establish per-instance and per-class-attribute
+instrumentation, respectively.
+
+The class instrumentation system can be customized on a per-class
+or global basis using the :mod:`sqlalchemy.ext.instrumentation`
+module, which provides the means to build and specify
+alternate instrumentation forms.
+
+.. versionchanged: 0.8
+   The instrumentation extension system was moved out of the
+   ORM and into the external :mod:`sqlalchemy.ext.instrumentation`
+   package.  When that package is imported, it installs
+   itself within sqlalchemy.orm so that its more comprehensive
+   resolution mechanics take effect.

+        This function is typically used behind the scenes

+        ``local_table``, ``properties``, and  ``inherits``.
+        Other options are passed to :func:`.mapper` using
+        the ``__mapper_args__`` class variable::

+            :ref:`classical_mapping` - discussion of direct usage of
+            :func:`.mapper`
+
+        :param class\_: The class to be mapped.  When using Declarative,
+          this argument is automatically passed as the declared class
+          itself.
+
+        :param local_table: The :class:`.Table` or other selectable
+           to which the class is mapped.  May be ``None`` if
+           this mapper inherits from another mapper using single-table
+           inheritance.   When using Declarative, this argument is
+           automatically passed by the extension, based on what
+           is configured via the ``__table__`` argument or via the
+           :class:`.Table` produced as a result of the ``__tablename__``
+           and :class:`.Column` arguments present.
+
+        :param always_refresh: If True, all query operations for this mapped
+           class will overwrite all data within object instances that already
+           exist within the session, erasing any in-memory changes with
+           whatever information was loaded from the database. Usage of this
+           flag is highly discouraged; as an alternative, see the method
+           :meth:`.Query.populate_existing`.
+
+        :param allow_partial_pks: Defaults to True.  Indicates that a
+           composite primary key with some NULL values should be considered as
+           possibly existing within the database. This affects whether a
+           mapper will assign an incoming row to an existing identity, as well
+           as if :meth:`.Session.merge` will check the database first for a
+           particular primary key value. A "partial primary key" can occur if
+           one has mapped to an OUTER JOIN, for example.
+
+        :param batch: Defaults to ``True``, indicating that save operations
+           of multiple entities can be batched together for efficiency.
+           Setting to False indicates
+           that an instance will be fully saved before saving the next
+           instance.  This is used in the extremely rare case that a
+           :class:`.MapperEvents` listener requires being called
+           in between individual row persistence operations.
+
+        :param column_prefix: A string which will be prepended
+           to the mapped attribute name when :class:`.Column`
+           objects are automatically assigned as attributes to the
+           mapped class.  Does not affect explicitly specified
+           column-based properties.
+
+           See the section :ref:`column_prefix` for an example.
+
+        :param concrete: If True, indicates this mapper should use concrete
+           table inheritance with its parent mapper.
+
+           See the section :ref:`concrete_inheritance` for an example.
+
+        :param confirm_deleted_rows: defaults to True; when a DELETE occurs
+          of one more rows based on specific primary keys, a warning is
+          emitted when the number of rows matched does not equal the number
+          of rows expected.  This parameter may be set to False to handle the
+          case where database ON DELETE CASCADE rules may be deleting some of
+          those rows automatically.  The warning may be changed to an
+          exception in a future release.
+
+          .. versionadded:: 0.9.4 - added
+             :paramref:`.mapper.confirm_deleted_rows` as well as conditional
+             matched row checking on delete.
+
+        :param eager_defaults: if True, the ORM will immediately fetch the
+          value of server-generated default values after an INSERT or UPDATE,
+          rather than leaving them as expired to be fetched on next access.
+          This can be used for event schemes where the server-generated values
+          are needed immediately before the flush completes.   By default,
+          this scheme will emit an individual ``SELECT`` statement per row
+          inserted or updated, which note can add significant performance
+          overhead.  However, if the
+          target database supports :term:`RETURNING`, the default values will
+          be returned inline with the INSERT or UPDATE statement, which can
+          greatly enhance performance for an application that needs frequent
+          access to just-generated server defaults.
+
+          .. versionchanged:: 0.9.0 The ``eager_defaults`` option can now
+             make use of :term:`RETURNING` for backends which support it.
+
+        :param exclude_properties: A list or set of string column names to
+          be excluded from mapping.
+
+          See :ref:`include_exclude_cols` for an example.
+
+        :param extension: A :class:`.MapperExtension` instance or
+           list of :class:`.MapperExtension` instances which will be applied
+           to all operations by this :class:`.Mapper`.  **Deprecated.**
+           Please see :class:`.MapperEvents`.
+
+        :param include_properties: An inclusive list or set of string column
+          names to map.
+
+          See :ref:`include_exclude_cols` for an example.
+
+        :param inherits: A mapped class or the corresponding :class:`.Mapper`
+          of one indicating a superclass to which this :class:`.Mapper`
+          should *inherit* from.   The mapped class here must be a subclass
+          of the other mapper's class.   When using Declarative, this argument
+          is passed automatically as a result of the natural class
+          hierarchy of the declared classes.

+        :param inherit_condition: For joined table inheritance, a SQL
+           expression which will
+           define how the two tables are joined; defaults to a natural join
+           between the two tables.
+
+        :param inherit_foreign_keys: When ``inherit_condition`` is used and
+           the columns present are missing a :class:`.ForeignKey`
+           configuration, this parameter can be used to specify which columns
+           are "foreign".  In most cases can be left as ``None``.
+
+        :param legacy_is_orphan: Boolean, defaults to ``False``.
+          When ``True``, specifies that "legacy" orphan consideration
+          is to be applied to objects mapped by this mapper, which means
+          that a pending (that is, not persistent) object is auto-expunged
+          from an owning :class:`.Session` only when it is de-associated
+          from *all* parents that specify a ``delete-orphan`` cascade towards
+          this mapper.  The new default behavior is that the object is
+          auto-expunged when it is de-associated with *any* of its parents
+          that specify ``delete-orphan`` cascade.  This behavior is more
+          consistent with that of a persistent object, and allows behavior to
+          be consistent in more scenarios independently of whether or not an
+          orphanable object has been flushed yet or not.
+
+          See the change note and example at :ref:`legacy_is_orphan_addition`
+          for more detail on this change.
+
+          .. versionadded:: 0.8 - the consideration of a pending object as
+            an "orphan" has been modified to more closely match the
+            behavior as that of persistent objects, which is that the object
+            is expunged from the :class:`.Session` as soon as it is
+            de-associated from any of its orphan-enabled parents.  Previously,
+            the pending object would be expunged only if de-associated
+            from all of its orphan-enabled parents. The new flag
+            ``legacy_is_orphan`` is added to :func:`.orm.mapper` which
+            re-establishes the legacy behavior.
+
+        :param non_primary: Specify that this :class:`.Mapper` is in addition
+          to the "primary" mapper, that is, the one used for persistence.
+          The :class:`.Mapper` created here may be used for ad-hoc
+          mapping of the class to an alternate selectable, for loading
+          only.
+
+          :paramref:`.Mapper.non_primary` is not an often used option, but
+          is useful in some specific :func:`.relationship` cases.

+          .. seealso::
+
+              :ref:`relationship_non_primary_mapper`
+
+        :param order_by: A single :class:`.Column` or list of :class:`.Column`
+           objects for which selection operations should use as the default
+           ordering for entities.  By default mappers have no pre-defined
+           ordering.
+
+        :param passive_updates: Indicates UPDATE behavior of foreign key
+           columns when a primary key column changes on a joined-table
+           inheritance mapping.   Defaults to ``True``.
+
+           When True, it is assumed that ON UPDATE CASCADE is configured on
+           the foreign key in the database, and that the database will handle
+           propagation of an UPDATE from a source column to dependent columns
+           on joined-table rows.
+
+           When False, it is assumed that the database does not enforce
+           referential integrity and will not be issuing its own CASCADE
+           operation for an update.  The unit of work process will
+           emit an UPDATE statement for the dependent columns during a
+           primary key change.

+        :param polymorphic_on: Specifies the column, attribute, or
+          SQL expression used to determine the target class for an
+          incoming row, when inheriting classes are present.
+
+          This value is commonly a :class:`.Column` object that's
+          present in the mapped :class:`.Table`::
+
+            class Employee(Base):
+                __tablename__ = 'employee'
+
+                id = Column(Integer, primary_key=True)
+                discriminator = Column(String(50))
+

+                    "polymorphic_identity":"employee"
+                }
+
+          It may also be specified
+          as a SQL expression, as in this example where we
+          use the :func:`.case` construct to provide a conditional
+          approach::
+
+            class Employee(Base):
+                __tablename__ = 'employee'
+
+                id = Column(Integer, primary_key=True)
+                discriminator = Column(String(50))
+
+                __mapper_args__ = {
+                    "polymorphic_on":case([
+                        (discriminator == "EN", "engineer"),
+                        (discriminator == "MA", "manager"),
+                    ], else_="employee"),
+                    "polymorphic_identity":"employee"
+                }
+
+          It may also refer to any attribute
+          configured with :func:`.column_property`, or to the
+          string name of one::
+
+                class Employee(Base):
+                    __tablename__ = 'employee'
+
+                    id = Column(Integer, primary_key=True)
+                    discriminator = Column(String(50))
+                    employee_type = column_property(
+                        case([
+                            (discriminator == "EN", "engineer"),
+                            (discriminator == "MA", "manager"),
+                        ], else_="employee")
+                    )
+
+                    __mapper_args__ = {
+                        "polymorphic_on":employee_type,
+                        "polymorphic_identity":"employee"

+
+          .. versionchanged:: 0.7.4
+              ``polymorphic_on`` may be specified as a SQL expression,
+              or refer to any attribute configured with
+              :func:`.column_property`, or to the string name of one.
+
+          When setting ``polymorphic_on`` to reference an
+          attribute or expression that's not present in the
+          locally mapped :class:`.Table`, yet the value
+          of the discriminator should be persisted to the database,
+          the value of the
+          discriminator is not automatically set on new
+          instances; this must be handled by the user,
+          either through manual means or via event listeners.
+          A typical approach to establishing such a listener
+          looks like::
+
+                from sqlalchemy import event
+                from sqlalchemy.orm import object_mapper
+
+                @event.listens_for(Employee, "init", propagate=True)
+                def set_identity(instance, *arg, **kw):
+                    mapper = object_mapper(instance)
+                    instance.discriminator = mapper.polymorphic_identity
+
+          Where above, we assign the value of ``polymorphic_identity``
+          for the mapped class to the ``discriminator`` attribute,
+          thus persisting the value to the ``discriminator`` column
+          in the database.
+
+          .. seealso::
+
+            :ref:`inheritance_toplevel`
+
+        :param polymorphic_identity: Specifies the value which
+          identifies this particular class as returned by the
+          column expression referred to by the ``polymorphic_on``
+          setting.  As rows are received, the value corresponding
+          to the ``polymorphic_on`` column expression is compared
+          to this value, indicating which subclass should
+          be used for the newly reconstructed object.
+
+        :param properties: A dictionary mapping the string names of object
+           attributes to :class:`.MapperProperty` instances, which define the
+           persistence behavior of that attribute.  Note that :class:`.Column`
+           objects present in
+           the mapped :class:`.Table` are automatically placed into
+           ``ColumnProperty`` instances upon mapping, unless overridden.
+           When using Declarative, this argument is passed automatically,
+           based on all those :class:`.MapperProperty` instances declared
+           in the declared class body.
+
+        :param primary_key: A list of :class:`.Column` objects which define
+           the primary key to be used against this mapper's selectable unit.
+           This is normally simply the primary key of the ``local_table``, but
+           can be overridden here.
+
+        :param version_id_col: A :class:`.Column`
+           that will be used to keep a running version id of rows
+           in the table.  This is used to detect concurrent updates or
+           the presence of stale data in a flush.  The methodology is to
+           detect if an UPDATE statement does not match the last known
+           version id, a
+           :class:`~sqlalchemy.orm.exc.StaleDataError` exception is
+           thrown.
+           By default, the column must be of :class:`.Integer` type,
+           unless ``version_id_generator`` specifies an alternative version
+           generator.

+
+        :param version_id_generator: Define how new version ids should
+          be generated.  Defaults to ``None``, which indicates that
+          a simple integer counting scheme be employed.  To provide a custom
+          versioning scheme, provide a callable function of the form::
+
+              def generate_version(version):
+                  return next_version
+
+          Alternatively, server-side versioning functions such as triggers,
+          or programmatic versioning schemes outside of the version id
+          generator may be used, by specifying the value ``False``.

+            has no effect on the state of data, and it can only return

+            is expired whenever the parent object is involved in a
+            flush, that is, has any kind of "dirty" state within a flush.
+            Setting this parameter to ``False`` will have the effect of
+            leaving any existing value present after the flush proceeds.
+            Note however that the :class:`.Session` with default expiration
+            settings still expires

+        and apply generatively, returning the newly resulting :class:`.Query`.
+
+        **Simple Relationship Joins**
+
+        Consider a mapping between two classes ``User`` and ``Address``,
+        with a relationship ``User.addresses`` representing a collection
+        of ``Address`` objects associated with each ``User``.   The most
+        common usage of :meth:`~.Query.join` is to create a JOIN along this
+        relationship, using the ``User.addresses`` attribute as an indicator
+        for how this should occur::
+
+            q = session.query(User).join(User.addresses)
+
+        Where above, the call to :meth:`~.Query.join` along ``User.addresses``
+        will result in SQL equivalent to::
+
+            SELECT user.* FROM user JOIN address ON user.id = address.user_id
+
+        In the above example we refer to ``User.addresses`` as passed to
+        :meth:`~.Query.join` as the *on clause*, that is, it indicates
+        how the "ON" portion of the JOIN should be constructed.  For a
+        single-entity query such as the one above (i.e. we start by selecting
+        only from ``User`` and nothing else), the relationship can also be
+        specified by its string name::
+
+            q = session.query(User).join("addresses")
+
+        :meth:`~.Query.join` can also accommodate multiple
+        "on clause" arguments to produce a chain of joins, such as below
+        where a join across four related entities is constructed::
+
+            q = session.query(User).join("orders", "items", "keywords")
+
+        The above would be shorthand for three separate calls to
+        :meth:`~.Query.join`, each using an explicit attribute to indicate
+        the source entity::
+
+            q = session.query(User).\\
+                    join(User.orders).\\
+                    join(Order.items).\\
+                    join(Item.keywords)
+
+        **Joins to a Target Entity or Selectable**
+
+        A second form of :meth:`~.Query.join` allows any mapped entity
+        or core selectable construct as a target.   In this usage,
+        :meth:`~.Query.join` will attempt
+        to create a JOIN along the natural foreign key relationship between
+        two entities::
+
+            q = session.query(User).join(Address)
+
+        The above calling form of :meth:`~.Query.join` will raise an error if
+        either there are no foreign keys between the two entities, or if
+        there are multiple foreign key linkages between them.   In the
+        above calling form, :meth:`~.Query.join` is called upon to
+        create the "on clause" automatically for us.  The target can
+        be any mapped entity or selectable, such as a :class:`.Table`::
+
+            q = session.query(User).join(addresses_table)
+
+        **Joins to a Target with an ON Clause**
+
+        The third calling form allows both the target entity as well
+        as the ON clause to be passed explicitly.   Suppose for
+        example we wanted to join to ``Address`` twice, using
+        an alias the second time.  We use :func:`~sqlalchemy.orm.aliased`
+        to create a distinct alias of ``Address``, and join
+        to it using the ``target, onclause`` form, so that the
+        alias can be specified explicitly as the target along with
+        the relationship to instruct how the ON clause should proceed::
+
+            a_alias = aliased(Address)
+
+            q = session.query(User).\\
+                    join(User.addresses).\\
+                    join(a_alias, User.addresses).\\
+                    filter(Address.email_address=='ed@foo.com').\\
+                    filter(a_alias.email_address=='ed@bar.com')
+
+        Where above, the generated SQL would be similar to::
+
+            SELECT user.* FROM user
+                JOIN address ON user.id = address.user_id
+                JOIN address AS address_1 ON user.id=address_1.user_id
+                WHERE address.email_address = :email_address_1
+                AND address_1.email_address = :email_address_2
+
+        The two-argument calling form of :meth:`~.Query.join`
+        also allows us to construct arbitrary joins with SQL-oriented
+        "on clause" expressions, not relying upon configured relationships
+        at all.  Any SQL expression can be passed as the ON clause
+        when using the two-argument form, which should refer to the target
+        entity in some way as well as an applicable source entity::
+
+            q = session.query(User).join(Address, User.id==Address.user_id)
+
+        .. versionchanged:: 0.7
+            In SQLAlchemy 0.6 and earlier, the two argument form of
+            :meth:`~.Query.join` requires the usage of a tuple:
+            ``query(User).join((Address, User.id==Address.user_id))``\ .
+            This calling form is accepted in 0.7 and further, though
+            is not necessary unless multiple join conditions are passed to
+            a single :meth:`~.Query.join` call, which itself is also not
+            generally necessary as it is now equivalent to multiple
+            calls (this wasn't always the case).
+
+        **Advanced Join Targeting and Adaption**
+
+        There is a lot of flexibility in what the "target" can be when using
+        :meth:`~.Query.join`.   As noted previously, it also accepts
+        :class:`.Table` constructs and other selectables such as
+        :func:`.alias` and :func:`.select` constructs, with either the one
+        or two-argument forms::
+
+            addresses_q = select([Address.user_id]).\\
+                        where(Address.email_address.endswith("@bar.com")).\\
+                        alias()
+
+            q = session.query(User).\\
+                        join(addresses_q, addresses_q.c.user_id==User.id)
+
+        :meth:`~.Query.join` also features the ability to *adapt* a
+        :meth:`~sqlalchemy.orm.relationship` -driven ON clause to the target
+        selectable. Below we construct a JOIN from ``User`` to a subquery
+        against ``Address``, allowing the relationship denoted by
+        ``User.addresses`` to *adapt* itself to the altered target::
+
+            address_subq = session.query(Address).\\
+                            filter(Address.email_address == 'ed@foo.com').\\
+                            subquery()
+
+            q = session.query(User).join(address_subq, User.addresses)
+
+        Producing SQL similar to::
+
+            SELECT user.* FROM user
+                JOIN (
+                    SELECT address.id AS id,
+                            address.user_id AS user_id,
+                            address.email_address AS email_address
+                    FROM address
+                    WHERE address.email_address = :email_address_1
+                ) AS anon_1 ON user.id = anon_1.user_id
+
+        The above form allows one to fall back onto an explicit ON
+        clause at any time::
+
+            q = session.query(User).\\
+                    join(address_subq, User.id==address_subq.c.user_id)
+
+        **Controlling what to Join From**
+
+        While :meth:`~.Query.join` exclusively deals with the "right"
+        side of the JOIN, we can also control the "left" side, in those
+        cases where it's needed, using :meth:`~.Query.select_from`.
+        Below we construct a query against ``Address`` but can still
+        make usage of ``User.addresses`` as our ON clause by instructing
+        the :class:`.Query` to select first from the ``User``
+        entity::
+
+            q = session.query(Address).select_from(User).\\
+                            join(User.addresses).\\
+                            filter(User.name == 'ed')
+
+        Which will produce SQL similar to::
+
+            SELECT address.* FROM user
+                JOIN address ON user.id=address.user_id
+                WHERE user.name = :name_1
+
+        **Constructing Aliases Anonymously**
+
+        :meth:`~.Query.join` can construct anonymous aliases
+        using the ``aliased=True`` flag.  This feature is useful
+        when a query is being joined algorithmically, such as
+        when querying self-referentially to an arbitrary depth::
+
+            q = session.query(Node).\\
+                    join("children", "children", aliased=True)
+
+        When ``aliased=True`` is used, the actual "alias" construct
+        is not explicitly available.  To work with it, methods such as
+        :meth:`.Query.filter` will adapt the incoming entity to
+        the last join point::
+
+            q = session.query(Node).\\
+                    join("children", "children", aliased=True).\\
+                    filter(Node.name == 'grandchild 1')
+
+        When using automatic aliasing, the ``from_joinpoint=True``
+        argument can allow a multi-node join to be broken into
+        multiple calls to :meth:`~.Query.join`, so that
+        each path along the way can be further filtered::
+
+            q = session.query(Node).\\
+                    join("children", aliased=True).\\
+                    filter(Node.name='child 1').\\
+                    join("children", aliased=True, from_joinpoint=True).\\
+                    filter(Node.name == 'grandchild 1')
+
+        The filtering aliases above can then be reset back to the
+        original ``Node`` entity using :meth:`~.Query.reset_joinpoint`::
+
+            q = session.query(Node).\\
+                    join("children", "children", aliased=True).\\
+                    filter(Node.name == 'grandchild 1').\\
+                    reset_joinpoint().\\
+                    filter(Node.name == 'parent 1)
+
+        For an example of ``aliased=True``, see the distribution
+        example :ref:`examples_xmlpersistence` which illustrates
+        an XPath-like query system using algorithmic joins.
+
+        :param \*props: A collection of one or more join conditions,
+         each consisting of a relationship-bound attribute or string
+         relationship name representing an "on clause", or a single
+         target entity, or a tuple in the form of ``(target, onclause)``.
+         A special two-argument calling form of the form ``target, onclause``
+         is also accepted.
+        :param aliased=False: If True, indicate that the JOIN target should be
+         anonymously aliased.  Subsequent calls to :meth:`~.Query.filter`
+         and similar will adapt the incoming criterion to the target
+         alias, until :meth:`~.Query.reset_joinpoint` is called.
+        :param from_joinpoint=False: When using ``aliased=True``, a setting
+         of True here will cause the join to be from the most recent
+         joined target, rather than starting back from the original
+         FROM clauses of the query.

+
+        This method is similar to the :meth:`.Query.select_from`
+        method, in that it sets the FROM clause of the query.  However,
+        where :meth:`.Query.select_from` only affects what is placed
+        in the FROM, this method also applies the given selectable
+        to replace the FROM which the selected entities would normally
+        select from.
+
+        The given ``from_obj`` must be an instance of a :class:`.FromClause`,
+        e.g. a :func:`.select` or :class:`.Alias` construct.
+
+        An example would be a :class:`.Query` that selects ``User`` entities,
+        but uses :meth:`.Query.select_entity_from` to have the entities
+        selected from a :func:`.select` construct instead of the
+        base ``user`` table::
+
+            select_stmt = select([User]).where(User.id == 7)
+
+            q = session.query(User).\\
+                    select_entity_from(select_stmt).\\
+                    filter(User.name == 'ed')
+
+        The query generated will select ``User`` entities directly
+        from the given :func:`.select` construct, and will be::
+
+            SELECT anon_1.id AS anon_1_id, anon_1.name AS anon_1_name
+            FROM (SELECT "user".id AS id, "user".name AS name
+            FROM "user"
+            WHERE "user".id = :id_1) AS anon_1
+            WHERE anon_1.name = :name_1
+
+        Notice above that even the WHERE criterion was "adapted" such that
+        the ``anon_1`` subquery effectively replaces all references to the
+        ``user`` table, except for the one that it refers to internally.
+
+        Compare this to :meth:`.Query.select_from`, which as of
+        version 0.9, does not affect existing entities.  The
+        statement below::
+
+            q = session.query(User).\\
+                    select_from(select_stmt).\\
+                    filter(User.name == 'ed')
+
+        Produces SQL where both the ``user`` table as well as the
+        ``select_stmt`` construct are present as separate elements
+        in the FROM clause.  No "adaptation" of the ``user`` table
+        is applied::
+
+            SELECT "user".id AS user_id, "user".name AS user_name
+            FROM "user", (SELECT "user".id AS id, "user".name AS name
+            FROM "user"
+            WHERE "user".id = :id_1) AS anon_1
+            WHERE "user".name = :name_1
+
+        :meth:`.Query.select_entity_from` maintains an older
+        behavior of :meth:`.Query.select_from`.  In modern usage,
+        similar results can also be achieved using :func:`.aliased`::
+
+            select_stmt = select([User]).where(User.id == 7)
+            user_from_select = aliased(User, select_stmt.alias())
+
+            q = session.query(user_from_select)
+
+        :param from_obj: a :class:`.FromClause` object that will replace

+
+        A typical :func:`.relationship`, used in a classical mapping::
+
+           mapper(Parent, properties={
+             'children': relationship(Child)
+           })
+
+        Some arguments accepted by :func:`.relationship` optionally accept a
+        callable function, which when called produces the desired value.
+        The callable is invoked by the parent :class:`.Mapper` at "mapper
+        initialization" time, which happens only when mappers are first used,
+        and is assumed to be after all mappings have been constructed.  This
+        can be used to resolve order-of-declaration and other dependency
+        issues, such as if ``Child`` is declared below ``Parent`` in the same

+
+        When using the :ref:`declarative_toplevel` extension, the Declarative
+        initializer allows string arguments to be passed to
+        :func:`.relationship`.  These string arguments are converted into
+        callables that evaluate the string as Python code, using the
+        Declarative class-registry as a namespace.  This allows the lookup of
+        related classes to be automatic via their string name, and removes the
+        need to import related classes at all into the local module space::
+
+            from sqlalchemy.ext.declarative import declarative_base

+          :paramref:`~.relationship.argument` may also be passed as a callable
+          function which is evaluated at mapper initialization time, and may
+          be passed as a Python-evaluable string when using Declarative.

+        :param secondary:
+          for a many-to-many relationship, specifies the intermediary

+          In less common circumstances, the argument may also be specified
+          as an :class:`.Alias` construct, or even a :class:`.Join` construct.
+
+          :paramref:`~.relationship.secondary` may
+          also be passed as a callable function which is evaluated at

+          present in the :class:`.MetaData` collection associated with the
+          parent-mapped :class:`.Table`.
+
+          The :paramref:`~.relationship.secondary` keyword argument is
+          typically applied in the case where the intermediary :class:`.Table`
+          is not otherwise exprssed in any direct class mapping. If the
+          "secondary" table is also explicitly mapped elsewhere (e.g. as in
+          :ref:`association_pattern`), one should consider applying the
+          :paramref:`~.relationship.viewonly` flag so that this
+          :func:`.relationship` is not used for persistence operations which
+          may conflict with those of the association object pattern.

+          When ``True``, indicates that the "previous" value for a
+          many-to-one reference should be loaded when replaced, if
+          not already loaded. Normally, history tracking logic for
+          simple many-to-ones only needs to be aware of the "new"
+          value in order to perform a flush. This flag is available

+          a comma-separated list of cascade rules which determines how

+          This defaults to ``False``, which means the default cascade
+          should be used - this default cascade is ``"save-update, merge"``.
+
+          The available cascades are ``save-update``, ``merge``,
+          ``expunge``, ``delete``, ``delete-orphan``, and ``refresh-expire``.
+          An additional option, ``all`` indicates shorthand for

+          expunge, delete"``, and is often used as in ``"all, delete-orphan"``
+          to indicate that related objects should follow along with the
+          parent object in all cases, and be deleted when de-associated.

+          When set to ``False``, the attribute managed by this relationship

+          the DISTINCT keyword will be applied in those cases when the target
+          columns do not comprise the full primary key of the target table.
+          When set to ``True``, the DISTINCT keyword is applied to the
+          innermost SELECT unconditionally.
+
+          It may be desirable to set this flag to False when the DISTINCT is
+          reducing performance of the innermost subquery beyond that of what

+
+        :param foreign_keys:
+
+          a list of columns which are to be used as "foreign key"
+          columns, or columns which refer to the value in a remote
+          column, within the context of this :func:`.relationship`
+          object's :paramref:`~.relationship.primaryjoin` condition.
+          That is, if the :paramref:`~.relationship.primaryjoin`
+          condition of this :func:`.relationship` is ``a.id ==
+          b.a_id``, and the values in ``b.a_id`` are required to be
+          present in ``a.id``, then the "foreign key" column of this
+          :func:`.relationship` is ``b.a_id``.
+
+          In normal cases, the :paramref:`~.relationship.foreign_keys`
+          parameter is **not required.** :func:`.relationship` will
+          automatically determine which columns in the
+          :paramref:`~.relationship.primaryjoin` conditition are to be
+          considered "foreign key" columns based on those
+          :class:`.Column` objects that specify :class:`.ForeignKey`,
+          or are otherwise listed as referencing columns in a
+          :class:`.ForeignKeyConstraint` construct.
+          :paramref:`~.relationship.foreign_keys` is only needed when:
+
+            1. There is more than one way to construct a join from the local
+               table to the remote table, as there are multiple foreign key
+               references present.  Setting ``foreign_keys`` will limit the
+               :func:`.relationship` to consider just those columns specified
+               here as "foreign".
+
+               .. versionchanged:: 0.8
+                    A multiple-foreign key join ambiguity can be resolved by
+                    setting the :paramref:`~.relationship.foreign_keys`
+                    parameter alone, without the need to explicitly set
+                    :paramref:`~.relationship.primaryjoin` as well.
+
+            2. The :class:`.Table` being mapped does not actually have
+               :class:`.ForeignKey` or :class:`.ForeignKeyConstraint`
+               constructs present, often because the table
+               was reflected from a database that does not support foreign key
+               reflection (MySQL MyISAM).
+
+            3. The :paramref:`~.relationship.primaryjoin` argument is used to
+               construct a non-standard join condition, which makes use of
+               columns or expressions that do not normally refer to their
+               "parent" column, such as a join condition expressed by a
+               complex comparison using a SQL function.
+
+          The :func:`.relationship` construct will raise informative
+          error messages that suggest the use of the
+          :paramref:`~.relationship.foreign_keys` parameter when
+          presented with an ambiguous condition.   In typical cases,
+          if :func:`.relationship` doesn't raise any exceptions, the
+          :paramref:`~.relationship.foreign_keys` parameter is usually
+          not needed.
+
+          :paramref:`~.relationship.foreign_keys` may also be passed as a
+          callable function which is evaluated at mapper initialization time,
+          and may be passed as a Python-evaluable string when using
+          Declarative.

+              The :func:`.foreign` annotation can also be applied
+              directly to the :paramref:`~.relationship.primaryjoin`
+              expression, which is an alternate, more specific system of
+              describing which columns in a particular
+              :paramref:`~.relationship.primaryjoin` should be considered
+              "foreign".

+
+        :param innerjoin=False:
+          when ``True``, joined eager loads will use an inner join to join
+          against related tables instead of an outer join.  The purpose
+          of this option is generally one of performance, as inner joins
+          generally perform better than outer joins.
+
+          This flag can be set to ``True`` when the relationship references an
+          object via many-to-one using local foreign keys that are not
+          nullable, or when the reference is one-to-one or a collection that
+          is guaranteed to have one or at least one entry.
+
+          If the joined-eager load is chained onto an existing LEFT OUTER
+          JOIN, ``innerjoin=True`` will be bypassed and the join will continue
+          to chain as LEFT OUTER JOIN so that the results don't change.  As an
+          alternative, specify the value ``"nested"``.  This will instead nest
+          the join on the right side, e.g. using the form "a LEFT OUTER JOIN
+          (b JOIN c)".
+
+          .. versionadded:: 0.9.4 Added ``innerjoin="nested"`` option to

+          relationship.  The number counts how many times the same Mapper
+          shall be present in the loading condition along a particular join
+          branch.  When left at its default of ``None``, eager loaders
+          will stop chaining when they encounter a the same target mapper
+          which is already higher up in the chain.  This option applies
+          both to joined- and subquery- eager loaders.

+
+        :param lazy='select': specifies
+          how the related items should be loaded.  Default value is
+          ``select``.  Values include:
+
+          * ``select`` - items should be loaded lazily when the property is
+            first accessed, using a separate SELECT statement, or identity map
+            fetch for simple many-to-one references.
+
+          * ``immediate`` - items should be loaded as the parents are loaded,
+            using a separate SELECT statement, or identity map fetch for
+            simple many-to-one references.
+
+          * ``joined`` - items should be loaded "eagerly" in the same query as
+            that of the parent, using a JOIN or LEFT OUTER JOIN.  Whether
+            the join is "outer" or not is determined by the
+            :paramref:`~.relationship.innerjoin` parameter.
+
+          * ``subquery`` - items should be loaded "eagerly" as the parents are
+            loaded, using one additional SQL statement, which issues a JOIN to
+            a subquery of the original statement, for each collection
+            requested.
+
+          * ``noload`` - no loading should occur at any time.  This is to
+            support "write-only" attributes, or attributes which are
+            populated in some manner specific to the application.
+
+          * ``dynamic`` - the attribute will return a pre-configured
+            :class:`.Query` object for all read
+            operations, onto which further filtering operations can be
+            applied before iterating the results.  See

+
+          * True - a synonym for 'select'

+
+        :param load_on_pending=False:
+          Indicates loading behavior for transient or pending parent objects.
+
+          When set to ``True``, causes the lazy-loader to
+          issue a query for a parent object that is not persistent, meaning it
+          has never been flushed.  This may take effect for a pending object
+          when autoflush is disabled, or for a transient object that has been
+          "attached" to a :class:`.Session` but is not part of its pending
+          collection.
+
+          The :paramref:`~.relationship.load_on_pending` flag does not improve
+          behavior when the ORM is used normally - object references should be
+          constructed at the object level, not at the foreign key level, so
+          that they are present in an ordinary way before a flush proceeds.
+          This flag is not not intended for general use.

+          .. seealso::
+
+              :meth:`.Session.enable_relationship_loading` - this method
+              establishes "load on pending" behavior for the whole object, and
+              also allows loading on objects that remain transient or
+              detached.
+
+        :param order_by:
+          indicates the ordering that should be applied when loading these
+          items.  :paramref:`~.relationship.order_by` is expected to refer to
+          one of the :class:`.Column` objects to which the target class is
+          mapped, or the attribute itself bound to the target class which
+          refers to the column.
+
+          :paramref:`~.relationship.order_by` may also be passed as a callable
+          function which is evaluated at mapper initialization time, and may
+          be passed as a Python-evaluable string when using Declarative.
+
+        :param passive_deletes=False:
+           Indicates loading behavior during delete operations.
+
+           A value of True indicates that unloaded child items should not
+           be loaded during a delete operation on the parent.  Normally,
+           when a parent item is deleted, all child items are loaded so
+           that they can either be marked as deleted, or have their
+           foreign key to the parent set to NULL.  Marking this flag as
+           True usually implies an ON DELETE <CASCADE|SET NULL> rule is in
+           place which will handle updating/deleting child rows on the
+           database side.
+
+           Additionally, setting the flag to the string value 'all' will
+           disable the "nulling out" of the child foreign keys, when there
+           is no delete or delete-orphan cascade enabled.  This is
+           typically used when a triggering or error raise scenario is in
+           place on the database side.  Note that the foreign key
+           attributes on in-session child objects will not be changed
+           after a flush occurs so this is a very special use-case
+           setting.
+
+           .. seealso::
+
+                :ref:`passive_deletes` - Introductory documentation
+                and examples.
+
+        :param passive_updates=True:
+          Indicates loading and INSERT/UPDATE/DELETE behavior when the
+          source of a foreign key value changes (i.e. an "on update"
+          cascade), which are typically the primary key columns of the
+          source row.
+
+          When True, it is assumed that ON UPDATE CASCADE is configured on
+          the foreign key in the database, and that the database will
+          handle propagation of an UPDATE from a source column to
+          dependent rows.  Note that with databases which enforce
+          referential integrity (i.e. PostgreSQL, MySQL with InnoDB tables),
+          ON UPDATE CASCADE is required for this operation.  The
+          relationship() will update the value of the attribute on related
+          items which are locally present in the session during a flush.
+
+          When False, it is assumed that the database does not enforce
+          referential integrity and will not be issuing its own CASCADE
+          operation for an update.  The relationship() will issue the
+          appropriate UPDATE statements to the database in response to the
+          change of a referenced key, and items locally present in the
+          session during a flush will also be refreshed.
+
+          This flag should probably be set to False if primary key changes
+          are expected and the database in use doesn't support CASCADE
+          (i.e. SQLite, MySQL MyISAM tables).

+              takes effect for joined-table inheritance mappings.
+
+        :param post_update:
+          this indicates that the relationship should be handled by a
+          second UPDATE statement after an INSERT or before a
+          DELETE. Currently, it also will issue an UPDATE after the
+          instance was UPDATEd as well, although this technically should
+          be improved. This flag is used to handle saving bi-directional
+          dependencies between two individual rows (i.e. each row
+          references the other), where it would otherwise be impossible to
+          INSERT or DELETE both rows fully since one row exists before the
+          other. Use this flag when a particular mapping arrangement will
+          incur two rows that are dependent on each other, such as a table
+          that has a one-to-many relationship to a set of child rows, and
+          also has a column that references a single child row within that
+          list (i.e. both tables contain a foreign key to each other). If
+          a flush operation returns an error that a "cyclical
+          dependency" was detected, this is a cue that you might want to
+          use :paramref:`~.relationship.post_update` to "break" the cycle.

+          automatically by :func:`.relationship` at mapper configuration
+          time, based on the type and direction
+          of the relationship - one to many forms a list, many to one
+          forms a scalar, many to many is a list. If a scalar is desired

+          existing :func:`.relationship` construct as a read-only attribute,

+              :paramref:`~.relationship.uselist` flag is needed.
+
+        :param viewonly=False:
+          when set to True, the relationship is used only for loading objects,

+          as well as SQL functions such as :func:`~.sql.expression.cast`.  The

+
+    """A :class:`.Session`-level transaction.
+
+    :class:`.SessionTransaction` is a mostly behind-the-scenes object
+    not normally referenced directly by application code.   It coordinates
+    among multiple :class:`.Connection` objects, maintaining a database
+    transaction for each one individually, committing or rolling them
+    back all at once.   It also provides optional two-phase commit behavior
+    which can augment this coordination operation.
+
+    The :attr:`.Session.transaction` attribute of :class:`.Session`
+    refers to the current :class:`.SessionTransaction` object in use, if any.
+
+
+    A :class:`.SessionTransaction` is associated with a :class:`.Session`
+    in its default mode of ``autocommit=False`` immediately, associated
+    with no database connections.  As the :class:`.Session` is called upon
+    to emit SQL on behalf of various :class:`.Engine` or :class:`.Connection`
+    objects, a corresponding :class:`.Connection` and associated
+    :class:`.Transaction` is added to a collection within the
+    :class:`.SessionTransaction` object, becoming one of the
+    connection/transaction pairs maintained by the
+    :class:`.SessionTransaction`.
+
+    The lifespan of the :class:`.SessionTransaction` ends when the
+    :meth:`.Session.commit`, :meth:`.Session.rollback` or
+    :meth:`.Session.close` methods are called.  At this point, the
+    :class:`.SessionTransaction` removes its association with its parent
+    :class:`.Session`.   A :class:`.Session` that is in ``autocommit=False``
+    mode will create a new :class:`.SessionTransaction` to replace it
+    immediately, whereas a :class:`.Session` that's in ``autocommit=True``
+    mode will remain without a :class:`.SessionTransaction` until the
+    :meth:`.Session.begin` method is called.
+
+    Another detail of :class:`.SessionTransaction` behavior is that it is
+    capable of "nesting".  This means that the :meth:`.Session.begin` method
+    can be called while an existing :class:`.SessionTransaction` is already
+    present, producing a new :class:`.SessionTransaction` that temporarily
+    replaces the parent :class:`.SessionTransaction`.   When a
+    :class:`.SessionTransaction` is produced as nested, it assigns itself to
+    the :attr:`.Session.transaction` attribute.  When it is ended via
+    :meth:`.Session.commit` or :meth:`.Session.rollback`, it restores its
+    parent :class:`.SessionTransaction` back onto the
+    :attr:`.Session.transaction` attribute.  The behavior is effectively a
+    stack, where :attr:`.Session.transaction` refers to the current head of
+    the stack.
+
+    The purpose of this stack is to allow nesting of
+    :meth:`.Session.rollback` or :meth:`.Session.commit` calls in context
+    with various flavors of :meth:`.Session.begin`. This nesting behavior
+    applies to when :meth:`.Session.begin_nested` is used to emit a
+    SAVEPOINT transaction, and is also used to produce a so-called
+    "subtransaction" which allows a block of code to use a
+    begin/rollback/commit sequence regardless of whether or not its enclosing
+    code block has begun a transaction.  The :meth:`.flush` method, whether
+    called explicitly or via autoflush, is the primary consumer of the
+    "subtransaction" feature, in that it wishes to guarantee that it works
+    within in a transaction block regardless of whether or not the
+    :class:`.Session` is in transactional mode when the method is called.

+        See also the :class:`.sessionmaker` function which is used to
+        generate a :class:`.Session`-producing callable with a given
+        set of arguments.
+
+        :param autocommit:
+
+          .. warning::
+
+             The autocommit flag is **not for general use**, and if it is
+             used, queries should only be invoked within the span of a
+             :meth:`.Session.begin` / :meth:`.Session.commit` pair.  Executing
+             queries outside of a demarcated transaction is a legacy mode
+             of usage, and can in some cases lead to concurrent connection
+             checkouts.
+
+          Defaults to ``False``. When ``True``, the
+          :class:`.Session` does not keep a persistent transaction running,
+          and will acquire connections from the engine on an as-needed basis,
+          returning them immediately after their use. Flushes will begin and
+          commit (or possibly rollback) their own transaction if no
+          transaction is present. When using this mode, the
+          :meth:`.Session.begin` method is used to explicitly start
+          transactions.
+
+          .. seealso::
+
+            :ref:`session_autocommit`
+
+        :param autoflush: When ``True``, all query operations will issue a
+           :meth:`~.Session.flush` call to this ``Session`` before proceeding.
+           This is a convenience feature so that :meth:`~.Session.flush` need
+           not be called repeatedly in order for database queries to retrieve
+           results. It's typical that ``autoflush`` is used in conjunction with
+           ``autocommit=False``. In this scenario, explicit calls to
+           :meth:`~.Session.flush` are rarely needed; you usually only need to
+           call :meth:`~.Session.commit` (which flushes) to finalize changes.
+
+        :param bind: An optional :class:`.Engine` or :class:`.Connection` to
+           which this ``Session`` should be bound. When specified, all SQL
+           operations performed by this session will execute via this
+           connectable.
+
+        :param binds: An optional dictionary which contains more granular
+           "bind" information than the ``bind`` parameter provides. This
+           dictionary can map individual :class`.Table`
+           instances as well as :class:`~.Mapper` instances to individual
+           :class:`.Engine` or :class:`.Connection` objects. Operations which
+           proceed relative to a particular :class:`.Mapper` will consult this
+           dictionary for the direct :class:`.Mapper` instance as
+           well as the mapper's ``mapped_table`` attribute in order to locate a
+           connectable to use. The full resolution is described in the
+           :meth:`.Session.get_bind`.
+           Usage looks like::
+
+            Session = sessionmaker(binds={
+                SomeMappedClass: create_engine('postgresql://engine1'),
+                somemapper: create_engine('postgresql://engine2'),
+                some_table: create_engine('postgresql://engine3'),
+                })
+
+          Also see the :meth:`.Session.bind_mapper`
+          and :meth:`.Session.bind_table` methods.
+
+        :param \class_: Specify an alternate class other than
+           ``sqlalchemy.orm.session.Session`` which should be used by the
+           returned class. This is the only argument that is local to the
+           :class:`.sessionmaker` function, and is not sent directly to the
+           constructor for ``Session``.
+
+        :param _enable_transaction_accounting:  Defaults to ``True``.  A
+           legacy-only flag which when ``False`` disables *all* 0.5-style
+           object accounting on transaction boundaries, including auto-expiry
+           of instances on rollback and commit, maintenance of the "new" and
+           "deleted" lists upon rollback, and autoflush of pending changes
+           upon :meth:`~.Session.begin`, all of which are interdependent.
+
+        :param expire_on_commit:  Defaults to ``True``. When ``True``, all
+           instances will be fully expired after each :meth:`~.commit`,
+           so that all attribute/object access subsequent to a completed
+           transaction will load from the most recent database state.
+
+        :param extension: An optional
+           :class:`~.SessionExtension` instance, or a list
+           of such instances, which will receive pre- and post- commit and
+           flush events, as well as a post-rollback event. **Deprecated.**
+           Please see :class:`.SessionEvents`.
+
+        :param info: optional dictionary of arbitrary data to be associated
+           with this :class:`.Session`.  Is available via the
+           :attr:`.Session.info` attribute.  Note the dictionary is copied at
+           construction time so that modifications to the per-
+           :class:`.Session` dictionary will be local to that
+           :class:`.Session`.
+
+           .. versionadded:: 0.9.0
+
+        :param query_cls:  Class which should be used to create new Query
+           objects, as returned by the :meth:`~.Session.query` method. Defaults
+           to :class:`.Query`.
+
+        :param twophase:  When ``True``, all transactions will be started as
+            a "two phase" transaction, i.e. using the "two phase" semantics
+            of the database in use along with an XID.  During a
+            :meth:`~.commit`, after :meth:`~.flush` has been issued for all
+            attached databases, the :meth:`~.TwoPhaseTransaction.prepare`
+            method on each database's :class:`.TwoPhaseTransaction` will be
+            called. This allows each database to roll back the entire
+            transaction, before each transaction is committed.
+
+        :param weak_identity_map:  Defaults to ``True`` - when set to
+           ``False``, objects placed in the :class:`.Session` will be
+           strongly referenced until explicitly removed or the
+           :class:`.Session` is closed.  **Deprecated** - this option
+           is obsolete.

+
+        The second positional argument to :meth:`.Session.execute` is an

+        dictionary, or a list of dictionaries, determines whether the DBAPI
+        cursor's ``execute()`` or ``executemany()`` is used to execute the
+        statement.   An INSERT construct may be invoked for a single row::
+
+            result = session.execute(
+                users.insert(), {"id": 7, "name": "somename"})
+
+        or for multiple rows::

+                                ])
+
+        The statement is executed within the current transactional context of
+        this :class:`.Session`.   The :class:`.Connection` which is used
+        to execute the statement can also be acquired directly by
+        calling the :meth:`.Session.connection` method.  Both methods use
+        a rule-based resolution scheme in order to determine the
+        :class:`.Connection`, which in the average case is derived directly
+        from the "bind" of the :class:`.Session` itself, and in other cases
+        can be based on the :func:`.mapper`
+        and :class:`.Table` objects passed to the method; see the
+        documentation for :meth:`.Session.get_bind` for a full description of
+        this scheme.
+
+        The :meth:`.Session.execute` method does *not* invoke autoflush.
+
+        The :class:`.ResultProxy` returned by the :meth:`.Session.execute`
+        method is returned with the "close_with_result" flag set to true;
+        the significance of this flag is that if this :class:`.Session` is
+        autocommitting and does not have a transaction-dedicated
+        :class:`.Connection` available, a temporary :class:`.Connection` is
+        established for the statement execution, which is closed (meaning,
+        returned to the connection pool) when the :class:`.ResultProxy` has
+        consumed all available data. This applies *only* when the
+        :class:`.Session` is configured with autocommit=True and no
+        transaction has been started.

+        :param instance: Instance to be merged.
+        :param load: Boolean, when False, :meth:`.merge` switches into
+         a "high performance" mode which causes it to forego emitting history
+         events as well as all database access.  This flag is used for
+         cases such as transferring graphs of objects into a :class:`.Session`
+         from a second level cache, or to transfer just-loaded objects
+         into the :class:`.Session` owned by a worker thread or process
+         without re-querying the database.
+
+         The ``load=False`` use case adds the caveat that the given
+         object has to be in a "clean" state, that is, has no pending changes
+         to be flushed - even if the incoming object is detached from any
+         :class:`.Session`.   This is so that when
+         the merge operation populates local attributes and
+         cascades to related objects and
+         collections, the values can be "stamped" onto the
+         target object as is, without generating any history or attribute
+         events, and without the need to reconcile the incoming data with
+         any existing related objects or collections that might not
+         be loaded.  The resulting objects from ``load=False`` are always
+         produced as "clean", so it is only appropriate that the given objects
+         should be "clean" as well, else this suggests a mis-use of the
+         method.

+            use cases and is not recommended for general use.
+
+        Accesses of attributes mapped with :func:`.relationship`
+        will attempt to load a value from the database using this
+        :class:`.Session` as the source of connectivity.  The values
+        will be loaded based on foreign key values present on this
+        object - it follows that this functionality
+        generally only works for many-to-one-relationships.
+
+        The object will be attached to this session, but will
+        **not** participate in any persistence operations; its state
+        for almost all purposes will remain either "transient" or
+        "detached", except for the case of relationship loading.
+
+        Also note that backrefs will often not work as expected.
+        Altering a relationship-bound attribute on the target object
+        may not fire off a backref event, if the effective value
+        is what was already loaded from a foreign-key-holding value.
+
+        The :meth:`.Session.enable_relationship_loading` method is
+        similar to the ``load_on_pending`` flag on :func:`.relationship`.
+        Unlike that flag, :meth:`.Session.enable_relationship_loading` allows
+        an object to remain transient while still being able to load
+        related items.
+
+        To make a transient object associated with a :class:`.Session`
+        via :meth:`.Session.enable_relationship_loading` pending, add
+        it to the :class:`.Session` using :meth:`.Session.add` normally.
+
+        :meth:`.Session.enable_relationship_loading` does not improve
+        behavior when the ORM is used normally - object references should be
+        constructed at the object level, not at the foreign key level, so
+        that they are present in an ordinary way before flush()
+        proceeds.  This method is not intended for general use.

+        This method retrieves the history for each instrumented

+        value to its previously committed value, if any.
+
+        It is in effect a more expensive and accurate
+        version of checking for the given instance in the
+        :attr:`.Session.dirty` collection; a full test for
+        each attribute's net "dirty" status is performed.

+        E.g.::
+
+            return session.is_modified(someobject)
+
+        .. versionchanged:: 0.8
+            When using SQLAlchemy 0.7 and earlier, the ``passive``
+            flag should **always** be explicitly set to ``True``,
+            else SQL loads/autoflushes may proceed which can affect
+            the modified state itself:
+            ``session.is_modified(someobject, passive=True)``\ .
+            In 0.8 and above, the behavior is corrected and
+            this flag is ignored.
+
+        A few caveats to this method apply:
+
+        * Instances present in the :attr:`.Session.dirty` collection may
+          report ``False`` when tested with this method.  This is because
+          the object may have received change events via attribute mutation,
+          thus placing it in :attr:`.Session.dirty`, but ultimately the state
+          is the same as that loaded from the database, resulting in no net
+          change here.
+        * Scalar attributes may not have recorded the previously set
+          value when a new value was applied, if the attribute was not loaded,
+          or was expired, at the time the new value was received - in these
+          cases, the attribute is assumed to have a change, even if there is
+          ultimately no net change against its database value. SQLAlchemy in
+          most cases does not need the "old" value when a set event occurs, so
+          it skips the expense of a SQL call if the old value isn't present,
+          based on the assumption that an UPDATE of the scalar value is
+          usually needed, and in those few cases where it isn't, is less
+          expensive on average than issuing a defensive SELECT.
+
+          The "old" value is fetched unconditionally upon set only if the
+          attribute container has the ``active_history`` flag set to ``True``.
+          This flag is set typically for primary key attributes and scalar
+          object references that are not a simple many-to-one.  To set this
+          flag for any arbitrary mapped column, use the ``active_history``
+          argument with :func:`.column_property`.
+
+        :param instance: mapped instance to be tested for pending changes.
+        :param include_collections: Indicates if multivalued collections
+         should be included in the operation.  Setting this to ``False`` is a
+         way to detect only local-column based properties (i.e. scalar columns
+         or many-to-one foreign keys) that would result in an UPDATE for this
+         instance upon flush.
+        :param passive:
+         .. versionchanged:: 0.8
+             Ignored for backwards compatibility.

+
+        The :class:`.Session` in its default mode of ``autocommit=False``
+        is essentially always in "transaction mode", in that a
+        :class:`.SessionTransaction` is associated with it as soon as
+        it is instantiated.  This :class:`.SessionTransaction` is immediately
+        replaced with a new one as soon as it is ended, due to a rollback,
+        commit, or close operation.
+
+        "Transaction mode" does *not* indicate whether
+        or not actual database connection resources are in use;  the
+        :class:`.SessionTransaction` object coordinates among zero or more
+        actual database transactions, and starts out with none, accumulating
+        individual DBAPI connections as different data sources are used
+        within its scope.   The best way to track when a particular
+        :class:`.Session` has actually begun to use DBAPI resources is to
+        implement a listener using the :meth:`.SessionEvents.after_begin`
+        method, which will deliver both the :class:`.Session` as well as the
+        target :class:`.Connection` to a user-defined event listener.
+
+        The "partial rollback" state refers to when an "inner" transaction,
+        typically used during a flush, encounters an error and emits a
+        rollback of the DBAPI connection.  At this point, the
+        :class:`.Session` is in "partial rollback" and awaits for the user to
+        call :meth:`.Session.rollback`, in order to close out the
+        transaction stack.  It is in this "partial rollback" period that the
+        :attr:`.is_active` flag returns False.  After the call to
+        :meth:`.Session.rollback`, the :class:`.SessionTransaction` is
+        replaced with a new one and :attr:`.is_active` returns ``True`` again.
+
+        When a :class:`.Session` is used in ``autocommit=True`` mode, the
+        :class:`.SessionTransaction` is only instantiated within the scope
+        of a flush call, or when :meth:`.Session.begin` is called.  So
+        :attr:`.is_active` will always be ``False`` outside of a flush or
+        :meth:`.Session.begin` block in this mode, and will be ``True``
+        within the :meth:`.Session.begin` block as long as it doesn't enter
+        "partial rollback" state.
+
+        From all the above, it follows that the only purpose to this flag is
+        for application frameworks that wish to detect is a "rollback" is
+        necessary within a generic error handling routine, for
+        :class:`.Session` objects that would otherwise be in
+        "partial rollback" mode.  In a typical integration case, this is also
+        not necessary as it is standard practice to emit
+        :meth:`.Session.rollback` unconditionally within the outermost
+        exception catch.
+
+        To track the transactional state of a :class:`.Session` fully,
+        use event listeners, primarily the :meth:`.SessionEvents.after_begin`,
+        :meth:`.SessionEvents.after_commit`,
+        :meth:`.SessionEvents.after_rollback` and related events.

+class Load(Generative, MapperOption):
+    """Represents loader options which modify the state of a
+    :class:`.Query` in order to affect how various mapped attributes are
+    loaded.
+
+    .. versionadded:: 0.9.0 The :meth:`.Load` system is a new foundation for
+       the existing system of loader options, including options such as
+       :func:`.orm.joinedload`, :func:`.orm.defer`, and others.   In
+       particular, it introduces a new method-chained system that replaces the
+       need for dot-separated paths as well as "_all()" options such as
+       :func:`.orm.joinedload_all`.
+
+    A :class:`.Load` object can be used directly or indirectly.  To use one
+    directly, instantiate given the parent class.  This style of usage is
+    useful when dealing with a :class:`.Query` that has multiple entities,
+    or when producing a loader option that can be applied generically to
+    any style of query::
+
+        myopt = Load(MyClass).joinedload("widgets")
+
+    The above ``myopt`` can now be used with :meth:`.Query.options`::
+
+        session.query(MyClass).options(myopt)
+
+    The :class:`.Load` construct is invoked indirectly whenever one makes use
+    of the various loader options that are present in ``sqlalchemy.orm``,
+    including options such as :func:`.orm.joinedload`, :func:`.orm.defer`,
+    :func:`.orm.subqueryload`, and all the rest.  These constructs produce an
+    "anonymous" form of the :class:`.Load` object which tracks attributes and
+    options, but is not linked to a parent class until it is associated with a
+    parent :class:`.Query`::
+
+        # produce "unbound" Load object
+        myopt = joinedload("widgets")
+
+        # when applied using options(), the option is "bound" to the
+        # class observed in the given query, e.g. MyClass
+        session.query(MyClass).options(myopt)
+
+    Whether the direct or indirect style is used, the :class:`.Load` object
+    returned now represents a specific "path" along the entities of a
+    :class:`.Query`.  This path can be traversed using a standard
+    method-chaining approach.  Supposing a class hierarchy such as ``User``,
+    ``User.addresses -> Address``, ``User.orders -> Order`` and
+    ``Order.items -> Item``, we can specify a variety of loader options along
+    each element in the "path"::
+
+        session.query(User).options(
+                    joinedload("addresses"),
+                    subqueryload("orders").joinedload("items")
+                )
+
+    Where above, the ``addresses`` collection will be joined-loaded, the
+    ``orders`` collection will be subquery-loaded, and within that subquery
+    load the ``items`` collection will be joined-loaded.

+    function is a variant of :func:`.aliased` that is intended to specify
+    a so-called "polymorphic selectable", that corresponds to the union

+
+    For convenience, the :func:`.aliased` function also accepts plain
+    :class:`.FromClause` constructs, such as a :class:`.Table` or
+    :func:`.select` construct.   In those cases, the :meth:`.FromClause.alias`

+    object, and to redirect compilation if a particular flag or condition
+    is found::
+
+        from sqlalchemy import schema
+        from sqlalchemy.ext.compiler import compiles
+

+            default = compiler.get_column_default_string(column)

+                            for const in column.constraints)
+            return text
+
+    The above construct can be applied to a :class:`.Table` as follows::
+
+        from sqlalchemy import Table, Metadata, Column, Integer, String
+        from sqlalchemy import schema
+
+        metadata = MetaData()
+
+        table = Table('mytable', MetaData(),
+                Column('x', Integer, info={"special":True}, primary_key=True),
+                Column('y', String(50)),
+                Column('z', String(20), info={"special":True})
+            )
+
+        metadata.create_all(conn)
+
+    Above, the directives we've added to the :attr:`.Column.info` collection
+    will be detected by our custom compilation scheme::
+
+        CREATE TABLE mytable (
+                x SPECIAL DIRECTIVE INTEGER NOT NULL,
+                y VARCHAR(50),
+                z SPECIAL DIRECTIVE VARCHAR(20),
+            PRIMARY KEY (x)
+        )
+
+    The :class:`.CreateColumn` construct can also be used to skip certain
+    columns when producing a ``CREATE TABLE``.  This is accomplished by
+    creating a compilation rule that conditionally returns ``None``.
+    This is essentially how to produce the same effect as using the
+    ``system=True`` argument on :class:`.Column`, which marks a column
+    as an implicitly-present "system" column.
+
+    For example, suppose we wish to produce a :class:`.Table` which skips
+    rendering of the Postgresql ``xmin`` column against the Postgresql
+    backend, but on other backends does render it, in anticipation of a
+    triggered rule.  A conditional compilation rule could skip this name only
+    on Postgresql::
+
+        from sqlalchemy.schema import CreateColumn
+
+        @compiles(CreateColumn, "postgresql")
+        def skip_xmin(element, compiler, **kw):
+            if element.element.name == 'xmin':
+                return None
+            else:
+                return compiler.visit_create_column(element, **kw)
+
+
+        my_table = Table('mytable', metadata,
+                    Column('id', Integer, primary_key=True),
+                    Column('xmin', Integer)
+                )
+
+    Above, a :class:`.CreateTable` construct will generate a ``CREATE TABLE``
+    which only includes the ``id`` column in the string; the ``xmin`` column
+    will be omitted, but only against the Postgresql backend.
+
+    .. versionadded:: 0.8.3 The :class:`.CreateColumn` construct supports
+       skipping of columns by returning ``None`` from a custom compilation
+       rule.
+

+        :meth:`.UpdateBase.returning` is not used simultaneously.  The column

+
+        This method differs from :meth:`.UpdateBase.returning` in these ways:
+
+        1. :meth:`.ValuesBase.return_defaults` is only intended for use with
+           an INSERT or an UPDATE statement that matches exactly one row.
+           While the RETURNING construct in the general sense supports
+           multiple rows for a multi-row UPDATE or DELETE statement, or for
+           special cases of INSERT that return multiple rows (e.g. INSERT from
+           SELECT, multi-valued VALUES clause),
+           :meth:`.ValuesBase.return_defaults` is intended only for an
+           "ORM-style" single-row INSERT/UPDATE statement.  The row returned
+           by the statement is also consumed implcitly when
+           :meth:`.ValuesBase.return_defaults` is used.  By contrast,
+           :meth:`.UpdateBase.returning` leaves the RETURNING result-set
+           intact with a collection of any number of rows.
+
+        2. It is compatible with the existing logic to fetch auto-generated
+           primary key values, also known as "implicit returning".  Backends
+           that support RETURNING will automatically make use of RETURNING in
+           order to fetch the value of newly generated primary keys; while the
+           :meth:`.UpdateBase.returning` method circumvents this behavior,
+           :meth:`.ValuesBase.return_defaults` leaves it intact.
+
+        3. It can be called against any backend.  Backends that don't support
+           RETURNING will skip the usage of the feature, rather than raising
+           an exception.  The return value of
+           :attr:`.ResultProxy.returned_defaults` will be ``None``
+
+        :meth:`.ValuesBase.return_defaults` is used by the ORM to provide

+          statement.   When compiled standalone without any parameters,
+          the ``SET`` clause generates for all columns.
+
+          Modern applications may prefer to use the generative
+          :meth:`.Update.values` method to set the values of the
+          UPDATE statement.
+
+        :param inline:
+          if True, SQL defaults present on :class:`.Column` objects via

+          be available in the dictionary returned from
+          :meth:`.ResultProxy.last_updated_params`.
+
+        If both ``values`` and compile-time bind parameters are present, the
+        compile-time bind parameters override the information specified
+        within ``values`` on a per-key basis.
+
+        The keys within ``values`` can be either :class:`.Column`
+        objects or their string identifiers (specifically the "key" of the
+        :class:`.Column`, normally but not necessarily equivalent to
+        its "name").  Normally, the
+        :class:`.Column` objects used here are expected to be
+        part of the target :class:`.Table` that is the table
+        to be updated.  However when using MySQL, a multiple-table
+        UPDATE statement can refer to columns from any of
+        the tables referred to in the WHERE clause.
+
+        The values referred to in ``values`` are typically:
+
+        * a literal data value (i.e. string, number, etc.)
+        * a SQL expression, such as a related :class:`.Column`,
+          a scalar-returning :func:`.select` construct,
+          etc.
+
+        When combining :func:`.select` constructs within the values
+        clause of an :func:`.update` construct,
+        the subquery represented by the :func:`.select` should be
+        *correlated* to the parent table, that is, providing criterion
+        which links the table inside the subquery to the outer table
+        being updated::
+
+            users.update().values(

+
+    While the most familiar kind of :class:`.ColumnElement` is the
+    :class:`.Column` object, :class:`.ColumnElement` serves as the basis
+    for any unit that may be present in a SQL expression, including
+    the expressions themselves, SQL functions, bound parameters,
+    literal expressions, keywords such as ``NULL``, etc.
+    :class:`.ColumnElement` is the ultimate base class for all such elements.
+
+    A wide variety of SQLAlchemy Core functions work at the SQL expression
+    level, and are intended to accept instances of :class:`.ColumnElement` as
+    arguments.  These functions will typically document that they accept a
+    "SQL expression" as an argument.  What this means in terms of SQLAlchemy
+    usually refers to an input which is either already in the form of a
+    :class:`.ColumnElement` object, or a value which can be **coerced** into
+    one.  The coercion rules followed by most, but not all, SQLAlchemy Core
+    functions with regards to SQL expressions are as follows:
+
+        * a literal Python value, such as a string, integer or floating
+          point value, boolean, datetime, ``Decimal`` object, or virtually
+          any other Python object, will be coerced into a "literal bound
+          value".  This generally means that a :func:`.bindparam` will be
+          produced featuring the given value embedded into the construct; the
+          resulting :class:`.BindParameter` object is an instance of
+          :class:`.ColumnElement`.  The Python value will ultimately be sent
+          to the DBAPI at execution time as a paramterized argument to the
+          ``execute()`` or ``executemany()`` methods, after SQLAlchemy
+          type-specific converters (e.g. those provided by any associated
+          :class:`.TypeEngine` objects) are applied to the value.
+
+        * any special object value, typically ORM-level constructs, which
+          feature a method called ``__clause_element__()``.  The Core
+          expression system looks for this method when an object of otherwise
+          unknown type is passed to a function that is looking to coerce the
+          argument into a :class:`.ColumnElement` expression.  The
+          ``__clause_element__()`` method, if present, should return a
+          :class:`.ColumnElement` instance.  The primary use of
+          ``__clause_element__()`` within SQLAlchemy is that of class-bound
+          attributes on ORM-mapped classes; a ``User`` class which contains a
+          mapped attribute named ``.name`` will have a method
+          ``User.name.__clause_element__()`` which when invoked returns the
+          :class:`.Column` called ``name`` associated with the mapped table.
+
+        * The Python ``None`` value is typically interpreted as ``NULL``,
+          which in SQLAlchemy Core produces an instance of :func:`.null`.
+
+    A :class:`.ColumnElement` provides the ability to generate new
+    :class:`.ColumnElement`
+    objects using Python expressions.  This means that Python operators
+    such as ``==``, ``!=`` and ``<`` are overloaded to mimic SQL operations,
+    and allow the instantiation of further :class:`.ColumnElement` instances
+    which are composed from other, more fundamental :class:`.ColumnElement`
+    objects.  For example, two :class:`.ColumnClause` objects can be added
+    together with the addition operator ``+`` to produce
+    a :class:`.BinaryExpression`.
+    Both :class:`.ColumnClause` and :class:`.BinaryExpression` are subclasses
+    of :class:`.ColumnElement`::
+
+        >>> from sqlalchemy.sql import column
+        >>> column('a') + column('b')
+        <sqlalchemy.sql.expression.BinaryExpression object at 0x101029dd0>

+        "placeholder" value in a SQL expression, the value of which is
+        supplied at the point at which the statement in executed against a
+        database connection.
+
+        In SQLAlchemy, the :func:`.bindparam` construct has
+        the ability to carry along the actual value that will be ultimately
+        used at expression time.  In this way, it serves not just as
+        a "placeholder" for eventual population, but also as a means of
+        representing so-called "unsafe" values which should not be rendered
+        directly in a SQL statement, but rather should be passed along
+        to the :term:`DBAPI` as values which need to be correctly escaped
+        and potentially handled for type-safety.
+
+        When using :func:`.bindparam` explicitly, the use case is typically
+        one of traditional deferment of parameters; the :func:`.bindparam`
+        construct accepts a name which can then be referred to at execution
+        time::
+
+            from sqlalchemy import bindparam
+
+            stmt = select([users_table]).\\
+                        where(users_table.c.name == bindparam('username'))
+
+        The above statement, when rendered, will produce SQL similar to::
+
+            SELECT id, name FROM user WHERE name = :username
+
+        In order to populate the value of ``:username`` above, the value
+        would typically be applied at execution time to a method
+        like :meth:`.Connection.execute`::
+
+            result = connection.execute(stmt, username='wendy')
+
+        Explicit use of :func:`.bindparam` is also common when producing
+        UPDATE or DELETE statements that are to be invoked multiple times,
+        where the WHERE criterion of the statement is to change on each
+        invocation, such as::
+
+            stmt = (users_table.update().
+                    where(user_table.c.name == bindparam('username')).
+                    values(fullname=bindparam('fullname'))
+                    )
+
+            connection.execute(
+                stmt, [{"username": "wendy", "fullname": "Wendy Smith"},
+                       {"username": "jack", "fullname": "Jack Jones"},
+                       ]
+            )
+
+        SQLAlchemy's Core expression system makes wide use of
+        :func:`.bindparam` in an implicit sense.   It is typical that Python
+        literal values passed to virtually all SQL expression functions are
+        coerced into fixed :func:`.bindparam` constructs.  For example, given
+        a comparison operation such as::
+
+            expr = users_table.c.name == 'Wendy'
+
+        The above expression will produce a :class:`.BinaryExpression`
+        construct, where the left side is the :class:`.Column` object
+        representing the ``name`` column, and the right side is a
+        :class:`.BindParameter` representing the literal value::
+
+            print(repr(expr.right))
+            BindParameter('%(4327771088 name)s', 'Wendy', type_=String())
+
+        The expression above will render SQL such as::
+
+            user.name = :name_1
+
+        Where the ``:name_1`` parameter name is an anonymous name.  The
+        actual string ``Wendy`` is not in the rendered string, but is carried
+        along where it is later used within statement execution.  If we
+        invoke a statement like the following::
+
+            stmt = select([users_table]).where(users_table.c.name == 'Wendy')
+            result = connection.execute(stmt)
+
+        We would see SQL logging output as::
+
+            SELECT "user".id, "user".name
+            FROM "user"
+            WHERE "user".name = %(name_1)s
+            {'name_1': 'Wendy'}
+
+        Above, we see that ``Wendy`` is passed as a parameter to the database,
+        while the placeholder ``:name_1`` is rendered in the appropriate form
+        for the target database, in this case the Postgresql database.
+
+        Similarly, :func:`.bindparam` is invoked automatically
+        when working with :term:`CRUD` statements as far as the "VALUES"
+        portion is concerned.   The :func:`.insert` construct produces an
+        ``INSERT`` expression which will, at statement execution time,
+        generate bound placeholders based on the arguments passed, as in::
+
+            stmt = users_table.insert()
+            result = connection.execute(stmt, name='Wendy')
+
+        The above will produce SQL output as::
+
+            INSERT INTO "user" (name) VALUES (%(name)s)
+            {'name': 'Wendy'}
+
+        The :class:`.Insert` construct, at compilation/execution time,
+        rendered a single :func:`.bindparam` mirroring the column
+        name ``name`` as a result of the single ``name`` parameter
+        we passed to the :meth:`.Connection.execute` method.
+
+        :param key:
+          the key (e.g. the name) for this bind param.
+          Will be used in the generated
+          SQL statement for dialects that use named parameters.  This
+          value may be modified when part of a compilation operation,
+          if other :class:`BindParameter` objects exist with the same
+          key, or if its length is too long and truncation is
+          required.
+
+        :param value:
+          Initial value for this bind param.  Will be used at statement
+          execution time as the value for this parameter passed to the
+          DBAPI, if no other value is indicated to the statement execution
+          method for this particular parameter name.  Defaults to ``None``.
+
+        :param callable\_:
+          A callable function that takes the place of "value".  The function
+          will be called at statement execution time to determine the
+          ultimate value.   Used for scenarios where the actual bind
+          value cannot be determined at the point at which the clause
+          construct is created, but embedded bind values are still desirable.
+
+        :param type\_:
+          A :class:`.TypeEngine` class or instance representing an optional
+          datatype for this :func:`.bindparam`.  If not passed, a type
+          may be determined automatically for the bind, based on the given
+          value; for example, trivial Python types such as ``str``,
+          ``int``, ``bool``
+          may result in the :class:`.String`, :class:`.Integer` or
+          :class:`.Boolean` types being autoamtically selected.
+
+          The type of a :func:`.bindparam` is significant especially in that
+          the type will apply pre-processing to the value before it is
+          passed to the database.  For example, a :func:`.bindparam` which
+          refers to a datetime value, and is specified as holding the
+          :class:`.DateTime` type, may apply conversion needed to the
+          value (such as stringification on SQLite) before passing the value
+          to the database.
+
+        :param unique:
+          if True, the key name of this :class:`.BindParameter` will be
+          modified if another :class:`.BindParameter` of the same name
+          already has been located within the containing
+          expression.  This flag is used generally by the internals
+          when producing so-called "anonymous" bound expressions, it
+          isn't generally applicable to explicitly-named :func:`.bindparam`
+          constructs.
+
+        :param required:
+          If ``True``, a value is required at execution time.  If not passed,
+          it defaults to ``True`` if neither :paramref:`.bindparam.value`
+          or :paramref:`.bindparam.callable` were passed.  If either of these
+          parameters are present, then :paramref:`.bindparam.required`
+          defaults to ``False``.
+
+          .. versionchanged:: 0.8 If the ``required`` flag is not specified,
+             it will be set automatically to ``True`` or ``False`` depending
+             on whether or not the ``value`` or ``callable`` parameters
+             were specified.
+
+        :param quote:
+          True if this parameter name requires quoting and is not
+          currently known as a SQLAlchemy reserved word; this currently
+          only applies to the Oracle backend, where bound names must
+          sometimes be quoted.
+
+        :param isoutparam:
+          if True, the parameter should be treated like a stored procedure

+        SQLAlchemy type constructs to play a role when executing
+        a statement that is specified literally.  The construct can also
+        be provided with a ``.c`` collection of column elements, allowing
+        it to be embedded in other SQL expression constructs as a subquery.
+
+        Bind parameters are specified by name, using the format ``:name``.
+        E.g.::
+
+            t = text("SELECT * FROM users WHERE id=:user_id")
+            result = connection.execute(t, user_id=12)
+
+        For SQL statements where a colon is required verbatim, as within
+        an inline string, use a backslash to escape::
+
+            t = text("SELECT * FROM users WHERE name='\\:username'")
+
+        The :class:`.TextClause` construct includes methods which can
+        provide information about the bound parameters as well as the column
+        values which would be returned from the textual statement, assuming
+        it's an executable SELECT type of statement.  The
+        :meth:`.TextClause.bindparams` method is used to provide bound
+        parameter detail, and :meth:`.TextClause.columns` method allows
+        specification of return columns including names and types::
+
+            t = text("SELECT * FROM users WHERE id=:user_id").\\
+                    bindparams(user_id=7).\\
+                    columns(id=Integer, name=String)
+
+            for id, name in connection.execute(t):
+                print(id, name)
+
+        The :func:`.text` construct is used internally in cases when
+        a literal string is specified for part of a larger query, such as
+        when a string is specified to the :meth:`.Select.where` method of
+        :class:`.Select`.  In those cases, the same
+        bind parameter syntax is applied::
+
+            s = select([users.c.id, users.c.name]).where("id=:user_id")
+            result = connection.execute(s, user_id=12)
+
+        Using :func:`.text` explicitly usually implies the construction
+        of a full, standalone statement.   As such, SQLAlchemy refers
+        to it as an :class:`.Executable` object, and it supports
+        the :meth:`Executable.execution_options` method.  For example,
+        a :func:`.text` construct that should be subject to "autocommit"
+        can be set explicitly so using the
+        :paramref:`.Connection.execution_options.autocommit` option::
+
+            t = text("EXEC my_procedural_thing()").\\
+                    execution_options(autocommit=True)
+
+        Note that SQLAlchemy's usual "autocommit" behavior applies to
+        :func:`.text` constructs implicitly - that is, statements which begin
+        with a phrase such as ``INSERT``, ``UPDATE``, ``DELETE``,
+        or a variety of other phrases specific to certain backends, will
+        be eligible for autocommit if no transaction is in progress.
+
+        :param text:
+          the text of the SQL statement to be created.  use ``:<param>``
+          to specify bind parameters; they will be compiled to their
+          engine-specific format.
+
+        :param autocommit:
+          Deprecated.  Use .execution_options(autocommit=<True|False>)
+          to set the autocommit option.
+
+        :param bind:
+          an optional connection or engine to be used for this text query.

+        :param bindparams:

+          provide information about parameters embedded in the statement.
+          This argument now invokes the :meth:`.TextClause.bindparams`
+          method on the construct before returning it.  E.g.::
+
+              stmt = text("SELECT * FROM table WHERE id=:id",
+                        bindparams=[bindparam('id', value=5, type_=Integer)])

+
+          .. deprecated:: 0.9.0 the :meth:`.TextClause.bindparams` method
+             supersedes the ``bindparams`` argument to :func:`.text`.
+

+          Deprecated.  A dictionary mapping the names of columns
+          represented in the columns clause of a ``SELECT`` statement
+          to type objects,
+          which will be used to perform post-processing on columns within
+          the result set.  This parameter now invokes the
+          :meth:`.TextClause.columns` method, which returns a
+          :class:`.TextAsFrom` construct that gains a ``.c`` collection and
+          can be embedded in other expressions.  E.g.::
+
+              stmt = text("SELECT * FROM table",

+        bind.  In the case of ``name`` we also set the default value of

+

+        SQL expressions, e.g. :class:`.ColumnElement` constructs, are accepted

+                (users_table.c.name == 'jack', 'J')
+            ])
+
+         In the second form, it accepts a Python dictionary of comparison
+         values mapped to a resulting value; this form requires
+         :paramref:`.case.value` to be present, and values will be compared
+         using the ``==`` operator, e.g.::
+
+            case(

+    ``True`` or ``False``, overrides automatic quoting behavior
+    for this identifier in order to either unconditionally quote
+    or to not quote the name.  If left at its default of ``None``,
+    quoting behavior is applied to the identifier on a per-backend basis
+    based on an examination of the token itself.
+
+    A :class:`.quoted_name` object with ``quote=True`` is also
+    prevented from being modified in the case of a so-called
+    "name normalize" option.  Certain database backends, such as
+    Oracle, Firebird, and DB2 "normalize" case-insensitive names
+    as uppercase.  The SQLAlchemy dialects for these backends
+    convert from SQLAlchemy's lower-case-means-insensitive convention
+    to the upper-case-means-insensitive conventions of those backends.
+    The ``quote=True`` flag here will prevent this conversion from occurring
+    to support an identifier that's quoted as all lower case against
+    such a backend.
+
+    The :class:`.quoted_name` object is normally created automatically
+    when specifying the name for key schema constructs such as
+    :class:`.Table`, :class:`.Column`, and others.  The class can also be
+    passed explicitly as the name to any function that receives a name which
+    can be quoted.  Such as to use the :meth:`.Engine.has_table` method with
+    an unconditionally quoted name::
+
+        from sqlaclchemy import create_engine
+        from sqlalchemy.sql.elements import quoted_name
+
+        engine = create_engine("oracle+cx_oracle://some_dsn")
+        engine.has_table(quoted_name("some_table", True))
+
+    The above logic will run the "has table" logic against the Oracle backend,

+

+    as follows::
+
+        m = MetaData(naming_convention={
+            "ck": "ck_%(table_name)s_%(constraint_name)s"

+
+    The name of the above constraint will be rendered as ``"ck_t_x5"``.
+    That is, the existing name ``x5`` is used in the naming convention as the
+    ``constraint_name`` token.
+
+    In some situations, such as in migration scripts, we may be rendering
+    the above :class:`.CheckConstraint` with a name that's already been
+    converted.  In order to make sure the name isn't double-modified, the
+    new name is applied using the :func:`.schema.conv` marker.  We can
+    use this explicitly as follows::
+
+
+        m = MetaData(naming_convention={
+            "ck": "ck_%(table_name)s_%(constraint_name)s"
+        })

+                        CheckConstraint('x > 5', name=conv('ck_t_x5')))
+
+    Where above, the :func:`.schema.conv` marker indicates that the constraint
+    name here is final, and the name will render as ``"ck_t_x5"`` and not
+    ``"ck_t_ck_t_x5"``

+        >>> print func.count(1)
+        count(:param_1)
+

+   used in that way::
+
+        >>> print select([func.count(table.c.id)])
+        SELECT count(sometable.id) FROM sometable
+
+   Any name can be given to :data:`.func`. If the function name is unknown to
+   SQLAlchemy, it will be rendered exactly as is. For common SQL functions
+   which SQLAlchemy is aware of, the name may be interpreted as a *generic
+   function* which will be compiled appropriately to the target database::
+
+        >>> print func.current_timestamp()
+        CURRENT_TIMESTAMP
+
+   To call functions which are present in dot-separated packages,
+   specify them in the same manner::
+
+        >>> print func.stats.yield_curve(5, 10)
+        stats.yield_curve(:yield_curve_1, :yield_curve_2)
+
+   SQLAlchemy can be made aware of the return type of functions to enable
+   type-specific lexical and result-based behavior. For example, to ensure
+   that a string-based function returns a Unicode value and is similarly
+   treated as a string in expressions, specify
+   :class:`~sqlalchemy.types.Unicode` as the type:
+
+        >>> print func.my_string(u'hi', type_=Unicode) + ' ' + \
+        ... func.my_string(u'there', type_=Unicode)
+        my_string(:my_string_1) || :my_string_2 || my_string(:my_string_3)
+
+   The object returned by a :data:`.func` call is usually an instance of
+   :class:`.Function`.
+   This object meets the "column" interface, including comparison and labeling
+   functions.  The object can also be passed the :meth:`~.Connectable.execute`
+   method of a :class:`.Connection` or :class:`.Engine`, where it will be
+   wrapped inside of a SELECT statement first::
+
+        print connection.execute(func.current_timestamp()).scalar()
+
+   In a few exception cases, the :data:`.func` accessor
+   will redirect a name to a built-in expression such as :func:`.cast`
+   or :func:`.extract`, as these names have well-known meaning
+   but are not exactly the same as "functions" from a SQLAlchemy
+   perspective.
+
+   .. versionadded:: 0.8 :data:`.func` can return non-function expression

+
+    A generic function is a pre-established :class:`.Function`
+    class that is instantiated automatically when called
+    by name from the :data:`.func` attribute.    Note that
+    calling any name from :data:`.func` has the effect that
+    a new :class:`.Function` instance is created automatically,
+    given that name.  The primary use case for defining
+    a :class:`.GenericFunction` class is so that a function
+    of a particular name may be given a fixed return type.
+    It can also include custom argument parsing schemes as well
+    as additional methods.
+
+    Subclasses of :class:`.GenericFunction` are automatically
+    registered under the name of the class.  For
+    example, a user-defined function ``as_utc()`` would
+    be available immediately::
+
+        from sqlalchemy.sql.functions import GenericFunction
+        from sqlalchemy.types import DateTime
+
+        class as_utc(GenericFunction):
+            type = DateTime
+
+        print select([func.as_utc()])
+
+    User-defined generic functions can be organized into
+    packages by specifying the "package" attribute when defining
+    :class:`.GenericFunction`.   Third party libraries
+    containing many functions may want to use this in order
+    to avoid name conflicts with other systems.   For example,
+    if our ``as_utc()`` function were part of a package
+    "time"::
+
+        class as_utc(GenericFunction):
+            type = DateTime
+            package = "time"
+
+    The above function would be available from :data:`.func`
+    using the package name ``time``::
+
+        print select([func.time.as_utc()])
+
+    A final option is to allow the function to be accessed
+    from one name in :data:`.func` but to render as a different name.
+    The ``identifier`` attribute will override the name used to
+    access the function as loaded from :data:`.func`, but will retain
+    the usage of ``name`` as the rendered name::
+
+        class GeoBuffer(GenericFunction):
+            type = Geometry
+            package = "geo"
+            name = "ST_Buffer"
+            identifier = "buffer"
+
+    The above function will render as follows::
+
+        >>> print func.geo.buffer()
+        ST_Buffer()
+
+    .. versionadded:: 0.8 :class:`.GenericFunction` now supports
+       automatic registration of new functions as well as package
+       and custom naming support.
+
+    .. versionchanged:: 0.8 The attribute name ``type`` is used
+       to specify the function's return type at the class level.
+       Previously, the name ``__return_type__`` was used.  This

+"""The schema module provides the building blocks for database metadata.
+
+Each element within this module describes a database entity which can be
+created and dropped, or is otherwise part of such an entity.  Examples include
+tables, columns, sequences, and indexes.
+
+All entities are subclasses of :class:`~sqlalchemy.schema.SchemaItem`, and as
+defined in this module they are intended to be agnostic of any vendor-specific
+constructs.
+
+A collection of entities are grouped into a unit called
+:class:`~sqlalchemy.schema.MetaData`. MetaData serves as a logical grouping of
+schema elements, and can also be associated with an actual database connection
+such that operations involving the contained elements can contact the database
+as needed.
+
+Two of the elements here also build upon their "syntactic" counterparts, which
+are defined in :class:`~sqlalchemy.sql.expression.`, specifically
+:class:`~sqlalchemy.schema.Table` and :class:`~sqlalchemy.schema.Column`.
+Since these objects are part of the SQL expression language, they are usable
+as components in SQL expressions.

+                   )
+
+    The :class:`.Table` object constructs a unique instance of itself based
+    on its name and optional schema name within the given
+    :class:`.MetaData` object. Calling the :class:`.Table`
+    constructor with the same name and same :class:`.MetaData` argument
+    a second time will return the *same* :class:`.Table` object - in this way
+    the :class:`.Table` constructor acts as a registry function.
+
+    .. seealso::
+
+        :ref:`metadata_describing` - Introduction to database metadata
+
+    Constructor arguments are as follows:
+
+    :param name: The name of this table as represented in the database.
+
+        The table name, along with the value of the ``schema`` parameter,
+        forms a key which uniquely identifies this :class:`.Table` within
+        the owning :class:`.MetaData` collection.
+        Additional calls to :class:`.Table` with the same name, metadata,
+        and schema name will return the same :class:`.Table` object.
+
+        Names which contain no upper case characters
+        will be treated as case insensitive names, and will not be quoted
+        unless they are a reserved word or contain special characters.
+        A name with any number of upper case characters is considered
+        to be case sensitive, and will be sent as quoted.
+
+        To enable unconditional quoting for the table name, specify the flag
+        ``quote=True`` to the constructor, or use the :class:`.quoted_name`
+        construct to specify the name.
+
+    :param metadata: a :class:`.MetaData` object which will contain this
+        table.  The metadata is used as a point of association of this table
+        with other tables which are referenced via foreign key.  It also
+        may be used to associate this table with a particular
+        :class:`.Connectable`.
+
+    :param \*args: Additional positional arguments are used primarily
+        to add the list of :class:`.Column` objects contained within this
+        table. Similar to the style of a CREATE TABLE statement, other
+        :class:`.SchemaItem` constructs may be added here, including
+        :class:`.PrimaryKeyConstraint`, and :class:`.ForeignKeyConstraint`.
+
+    :param autoload: Defaults to False: the Columns for this table should
+        be reflected from the database. Usually there will be no Column
+        objects in the constructor if this property is set.
+
+    :param autoload_replace: If ``True``, when using ``autoload=True``
+        and ``extend_existing=True``,
+        replace ``Column`` objects already present in the ``Table`` that's
+        in the ``MetaData`` registry with
+        what's reflected.  Otherwise, all existing columns will be
+        excluded from the reflection process.    Note that this does
+        not impact ``Column`` objects specified in the same call to ``Table``
+        which includes ``autoload``, those always take precedence.
+        Defaults to ``True``.
+
+        .. versionadded:: 0.7.5
+
+    :param autoload_with: If autoload==True, this is an optional Engine
+        or Connection instance to be used for the table reflection. If
+        ``None``, the underlying MetaData's bound connectable will be used.
+
+    :param extend_existing: When ``True``, indicates that if this
+        :class:`.Table` is already present in the given :class:`.MetaData`,
+        apply further arguments within the constructor to the existing
+        :class:`.Table`.
+
+        If ``extend_existing`` or ``keep_existing`` are not set, an error is
+        raised if additional table modifiers are specified when
+        the given :class:`.Table` is already present in the
+        :class:`.MetaData`.
+
+        .. versionchanged:: 0.7.4
+            ``extend_existing`` will work in conjunction
+            with ``autoload=True`` to run a new reflection operation against
+            the database; new :class:`.Column` objects will be produced
+            from database metadata to replace those existing with the same
+            name, and additional :class:`.Column` objects not present
+            in the :class:`.Table` will be added.
+
+        As is always the case with ``autoload=True``, :class:`.Column`
+        objects can be specified in the same :class:`.Table` constructor,
+        which will take precedence.  I.e.::
+
+            Table("mytable", metadata,
+                        Column('y', Integer),
+                        extend_existing=True,
+                        autoload=True,
+                        autoload_with=engine
+                    )
+
+        The above will overwrite all columns within ``mytable`` which
+        are present in the database, except for ``y`` which will be used as is
+        from the above definition.   If the ``autoload_replace`` flag
+        is set to False, no existing columns will be replaced.
+
+    :param implicit_returning: True by default - indicates that
+        RETURNING can be used by default to fetch newly inserted primary key
+        values, for backends which support this.  Note that
+        create_engine() also provides an implicit_returning flag.
+
+    :param include_columns: A list of strings indicating a subset of
+        columns to be loaded via the ``autoload`` operation; table columns who
+        aren't present in this list will not be represented on the resulting
+        ``Table`` object. Defaults to ``None`` which indicates all columns
+        should be reflected.
+
+    :param info: Optional data dictionary which will be populated into the
+        :attr:`.SchemaItem.info` attribute of this object.
+
+    :param keep_existing: When ``True``, indicates that if this Table
+        is already present in the given :class:`.MetaData`, ignore
+        further arguments within the constructor to the existing
+        :class:`.Table`, and return the :class:`.Table` object as
+        originally created. This is to allow a function that wishes
+        to define a new :class:`.Table` on first call, but on
+        subsequent calls will return the same :class:`.Table`,
+        without any of the declarations (particularly constraints)
+        being applied a second time. Also see extend_existing.
+
+        If extend_existing or keep_existing are not set, an error is
+        raised if additional table modifiers are specified when
+        the given :class:`.Table` is already present in the
+        :class:`.MetaData`.
+
+    :param listeners: A list of tuples of the form ``(<eventname>, <fn>)``
+        which will be passed to :func:`.event.listen` upon construction.
+        This alternate hook to :func:`.event.listen` allows the establishment
+        of a listener function specific to this :class:`.Table` before
+        the "autoload" process begins.  Particularly useful for
+        the :meth:`.DDLEvents.column_reflect` event::
+
+            def listen_for_reflect(table, column_info):
+                "handle the column reflection event"
+                # ...
+
+            t = Table(
+                'sometable',
+                autoload=True,
+                listeners=[
+                    ('column_reflect', listen_for_reflect)
+                ])
+
+    :param mustexist: When ``True``, indicates that this Table must already
+        be present in the given :class:`.MetaData` collection, else
+        an exception is raised.
+
+    :param prefixes:
+        A list of strings to insert after CREATE in the CREATE TABLE
+        statement.  They will be separated by spaces.
+
+    :param quote: Force quoting of this table's name on or off, corresponding
+        to ``True`` or ``False``.  When left at its default of ``None``,
+        the column identifier will be quoted according to whether the name is
+        case sensitive (identifiers with at least one upper case character are
+        treated as case sensitive), or if it's a reserved word.  This flag
+        is only needed to force quoting of a reserved word which is not known
+        by the SQLAlchemy dialect.
+
+    :param quote_schema: same as 'quote' but applies to the schema identifier.
+
+    :param schema: The schema name for this table, which is required if
+        the table resides in a schema other than the default selected schema
+        for the engine's database connection.  Defaults to ``None``.
+
+        The quoting rules for the schema name are the same as those for the
+        ``name`` parameter, in that quoting is applied for reserved words or
+        case-sensitive names; to enable unconditional quoting for the

+        Construct a new ``Column`` object.
+
+        :param name: The name of this column as represented in the database.
+          This argument may be the first positional argument, or specified
+          via keyword.
+
+          Names which contain no upper case characters
+          will be treated as case insensitive names, and will not be quoted
+          unless they are a reserved word.  Names with any number of upper
+          case characters will be quoted and sent exactly.  Note that this
+          behavior applies even for databases which standardize upper
+          case names as case insensitive such as Oracle.
+
+          The name field may be omitted at construction time and applied
+          later, at any time before the Column is associated with a
+          :class:`.Table`.  This is to support convenient
+          usage within the :mod:`~sqlalchemy.ext.declarative` extension.
+
+        :param type\_: The column's type, indicated using an instance which
+          subclasses :class:`~sqlalchemy.types.TypeEngine`.  If no arguments
+          are required for the type, the class of the type can be sent
+          as well, e.g.::
+
+            # use a type with arguments
+            Column('data', String(50))
+
+            # use no arguments
+            Column('level', Integer)
+
+          The ``type`` argument may be the second positional argument
+          or specified by keyword.
+
+          If the ``type`` is ``None`` or is omitted, it will first default to
+          the special type :class:`.NullType`.  If and when this
+          :class:`.Column` is made to refer to another column using
+          :class:`.ForeignKey` and/or :class:`.ForeignKeyConstraint`, the type
+          of the remote-referenced column will be copied to this column as
+          well, at the moment that the foreign key is resolved against that
+          remote :class:`.Column` object.
+
+          .. versionchanged:: 0.9.0
+            Support for propagation of type to a :class:`.Column` from its
+            :class:`.ForeignKey` object has been improved and should be
+            more reliable and timely.
+
+        :param \*args: Additional positional arguments include various
+          :class:`.SchemaItem` derived constructs which will be applied
+          as options to the column.  These include instances of
+          :class:`.Constraint`, :class:`.ForeignKey`, :class:`.ColumnDefault`,
+          and :class:`.Sequence`.  In some cases an equivalent keyword
+          argument is available such as ``server_default``, ``default``
+          and ``unique``.
+
+        :param autoincrement: This flag may be set to ``False`` to
+          indicate an integer primary key column that should not be
+          considered to be the "autoincrement" column, that is
+          the integer primary key column which generates values
+          implicitly upon INSERT and whose value is usually returned
+          via the DBAPI cursor.lastrowid attribute.   It defaults
+          to ``True`` to satisfy the common use case of a table
+          with a single integer primary key column.  If the table
+          has a composite primary key consisting of more than one
+          integer column, set this flag to True only on the
+          column that should be considered "autoincrement".
+
+          The setting *only* has an effect for columns which are:
+
+          * Integer derived (i.e. INT, SMALLINT, BIGINT).
+
+          * Part of the primary key
+
+          * Not refering to another column via :class:`.ForeignKey`, unless
+            the value is specified as ``'ignore_fk'``::
+
+                # turn on autoincrement for this column despite
+                # the ForeignKey()
+                Column('id', ForeignKey('other.id'),
+                            primary_key=True, autoincrement='ignore_fk')
+
+            It is typically not desirable to have "autoincrement" enabled
+            on such a column as its value intends to mirror that of a
+            primary key column elsewhere.
+
+          * have no server side or client side defaults (with the exception
+            of Postgresql SERIAL).
+
+          The setting has these two effects on columns that meet the
+          above criteria:
+
+          * DDL issued for the column will include database-specific
+            keywords intended to signify this column as an
+            "autoincrement" column, such as AUTO INCREMENT on MySQL,
+            SERIAL on Postgresql, and IDENTITY on MS-SQL.  It does
+            *not* issue AUTOINCREMENT for SQLite since this is a
+            special SQLite flag that is not required for autoincrementing
+            behavior.
+
+            .. seealso::
+
+                :ref:`sqlite_autoincrement`
+
+          * The column will be considered to be available as
+            cursor.lastrowid or equivalent, for those dialects which
+            "post fetch" newly inserted identifiers after a row has
+            been inserted (SQLite, MySQL, MS-SQL).  It does not have
+            any effect in this regard for databases that use sequences
+            to generate primary key identifiers (i.e. Firebird, Postgresql,
+            Oracle).
+
+          .. versionchanged:: 0.7.4
+              ``autoincrement`` accepts a special value ``'ignore_fk'``
+              to indicate that autoincrementing status regardless of foreign
+              key references.  This applies to certain composite foreign key
+              setups, such as the one demonstrated in the ORM documentation
+              at :ref:`post_update`.
+
+        :param default: A scalar, Python callable, or
+            :class:`.ColumnElement` expression representing the
+            *default value* for this column, which will be invoked upon insert
+            if this column is otherwise not specified in the VALUES clause of
+            the insert. This is a shortcut to using :class:`.ColumnDefault` as
+            a positional argument; see that class for full detail on the
+            structure of the argument.
+
+            Contrast this argument to ``server_default`` which creates a
+            default generator on the database side.
+
+        :param doc: optional String that can be used by the ORM or similar
+            to document attributes.   This attribute does not render SQL
+            comments (a future attribute 'comment' will achieve that).
+
+        :param key: An optional string identifier which will identify this
+            ``Column`` object on the :class:`.Table`. When a key is provided,
+            this is the only identifier referencing the ``Column`` within the
+            application, including ORM attribute mapping; the ``name`` field
+            is used only when rendering SQL.
+
+        :param index: When ``True``, indicates that the column is indexed.
+            This is a shortcut for using a :class:`.Index` construct on the
+            table. To specify indexes with explicit names or indexes that
+            contain multiple columns, use the :class:`.Index` construct
+            instead.
+
+        :param info: Optional data dictionary which will be populated into the
+            :attr:`.SchemaItem.info` attribute of this object.
+
+        :param nullable: If set to the default of ``True``, indicates the
+            column will be rendered as allowing NULL, else it's rendered as
+            NOT NULL. This parameter is only used when issuing CREATE TABLE
+            statements.
+
+        :param onupdate: A scalar, Python callable, or
+            :class:`~sqlalchemy.sql.expression.ClauseElement` representing a
+            default value to be applied to the column within UPDATE
+            statements, which wil be invoked upon update if this column is not
+            present in the SET clause of the update. This is a shortcut to
+            using :class:`.ColumnDefault` as a positional argument with
+            ``for_update=True``.
+
+        :param primary_key: If ``True``, marks this column as a primary key
+            column. Multiple columns can have this flag set to specify
+            composite primary keys. As an alternative, the primary key of a
+            :class:`.Table` can be specified via an explicit
+            :class:`.PrimaryKeyConstraint` object.
+
+        :param server_default: A :class:`.FetchedValue` instance, str, Unicode
+            or :func:`~sqlalchemy.sql.expression.text` construct representing
+            the DDL DEFAULT value for the column.
+
+            String types will be emitted as-is, surrounded by single quotes::
+
+                Column('x', Text, server_default="val")
+
+                x TEXT DEFAULT 'val'
+
+            A :func:`~sqlalchemy.sql.expression.text` expression will be
+            rendered as-is, without quotes::
+
+                Column('y', DateTime, server_default=text('NOW()'))
+
+                y DATETIME DEFAULT NOW()
+
+            Strings and text() will be converted into a
+            :class:`.DefaultClause` object upon initialization.
+
+            Use :class:`.FetchedValue` to indicate that an already-existing
+            column will generate a default value on the database side which
+            will be available to SQLAlchemy for post-fetch after inserts. This
+            construct does not specify any DDL and the implementation is left
+            to the database, such as via a trigger.
+
+        :param server_onupdate:   A :class:`.FetchedValue` instance
+             representing a database-side default generation function. This
+             indicates to SQLAlchemy that a newly generated value will be
+             available after updates. This construct does not specify any DDL
+             and the implementation is left to the database, such as via a
+             trigger.
+
+        :param quote: Force quoting of this column's name on or off,
+             corresponding to ``True`` or ``False``. When left at its default
+             of ``None``, the column identifier will be quoted according to
+             whether the name is case sensitive (identifiers with at least one
+             upper case character are treated as case sensitive), or if it's a
+             reserved word. This flag is only needed to force quoting of a
+             reserved word which is not known by the SQLAlchemy dialect.
+
+        :param unique: When ``True``, indicates that this column contains a
+             unique constraint, or if ``index`` is ``True`` as well, indicates
+             that the :class:`.Index` should be created with the unique flag.
+             To specify multiple columns in the constraint/index or to specify
+             an explicit name, use the :class:`.UniqueConstraint` or
+             :class:`.Index` constructs explicitly.
+
+        :param system: When ``True``, indicates this is a "system" column,
+             that is a column which is automatically made available by the
+             database, and should not be included in the columns list for a
+             ``CREATE TABLE`` statement.
+
+             For more elaborate scenarios where columns should be
+             conditionally rendered differently on different backends,
+             consider custom compilation rules for :class:`.CreateColumn`.
+
+             ..versionadded:: 0.8.3 Added the ``system=True`` parameter to
+               :class:`.Column`.

+
+    The :class:`.PrimaryKeyConstraint` object is present automatically
+    on any :class:`.Table` object; it is assigned a set of
+    :class:`.Column` objects corresponding to those marked with
+    the :paramref:`.Column.primary_key` flag::
+
+        >>> my_table = Table('mytable', metadata,

+                   primary_key=True, nullable=False)
+        )
+
+    The primary key of a :class:`.Table` can also be specified by using
+    a :class:`.PrimaryKeyConstraint` object explicitly; in this mode of usage,
+    the "name" of the constraint can also be specified, as well as other
+    options which may be recognized by dialects::
+
+        my_table = Table('mytable', metadata,

+    An warning is emitted if the columns present in the
+    :class:`.PrimaryKeyConstraint`
+    don't match the columns that were marked as ``primary_key=True``, if both
+    are present; in this case, the columns are taken strictly from the
+    :class:`.PrimaryKeyConstraint` declaration, and those columns otherwise
+    marked as ``primary_key=True`` are ignored.  This behavior is intended to
+    be backwards compatible with previous behavior.
+
+    .. versionchanged:: 0.9.2  Using a mixture of columns within a
+       :class:`.PrimaryKeyConstraint` in addition to columns marked as
+       ``primary_key=True`` now emits a warning if the lists don't match.
+       The ultimate behavior of ignoring those columns marked with the flag
+       only is currently maintained for backwards compatibility; this warning
+       may raise an exception in a future release.
+
+    For the use case where specific options are to be specified on the
+    :class:`.PrimaryKeyConstraint`, but the usual style of using
+    ``primary_key=True`` flags is still desirable, an empty
+    :class:`.PrimaryKeyConstraint` may be specified, which will take on the
+    primary key column collection from the :class:`.Table` based on the

+          and :class:`.Index` objects, for those objects which are not given
+          a name explicitly.
+
+          The keys of this dictionary may be:
+
+          * a constraint or Index class, e.g. the :class:`.UniqueConstraint`,
+            :class:`.ForeignKeyConstraint` class, the :class:`.Index` class
+
+          * a string mnemonic for one of the known constraint classes;
+            ``"fk"``, ``"pk"``, ``"ix"``, ``"ck"``, ``"uq"`` for foreign key,
+            primary key, index, check, and unique constraint, respectively.
+
+          * the string name of a user-defined "token" that can be used
+            to define new naming tokens.
+
+          The values associated with each "constraint class" or "constraint
+          mnemonic" key are string naming templates, such as
+          ``"uq_%(table_name)s_%(column_0_name)s"``,
+          which describe how the name should be composed.  The values
+          associated with user-defined "token" keys should be callables of the
+          form ``fn(constraint, table)``, which accepts the constraint/index
+          object and :class:`.Table` as arguments, returning a string
+          result.
+
+          The built-in names are as follows, some of which may only be
+          available for certain types of constraint:
+
+            * ``%(table_name)s`` - the name of the :class:`.Table` object
+              associated with the constraint.
+
+            * ``%(referred_table_name)s`` - the name of the :class:`.Table`
+              object associated with the referencing target of a
+              :class:`.ForeignKeyConstraint`.
+
+            * ``%(column_0_name)s`` - the name of the :class:`.Column` at
+              index position "0" within the constraint.
+
+            * ``%(column_0_label)s`` - the label of the :class:`.Column` at
+              index position "0", e.g. :attr:`.Column.label`
+
+            * ``%(column_0_key)s`` - the key of the :class:`.Column` at
+              index position "0", e.g. :attr:`.Column.key`
+
+            * ``%(referred_column_0_name)s`` - the name of a :class:`.Column`
+              at index position "0" referenced by a
+              :class:`.ForeignKeyConstraint`.
+
+            * ``%(constraint_name)s`` - a special key that refers to the
+              existing name given to the constraint.  When this key is
+              present, the :class:`.Constraint` object's existing name will be
+              replaced with one that is composed from template string that
+              uses this token. When this token is present, it is required that
+              the :class:`.Constraint` is given an expicit name ahead of time.
+
+            * user-defined: any additional token may be implemented by passing
+              it along with a ``fn(constraint, table)`` callable to the
+              naming_convention dictionary.

+        the ``.c.`` collection of the resulting :class:`.Alias` represents
+        the names of the individual columns using a
+        ``<tablename>_<columname>`` scheme::
+
+            j.c.table_a_id
+            j.c.table_b_a_id
+
+        :meth:`.Join.alias` also features an alternate
+        option for aliasing joins which produces no enclosing SELECT and
+        does not normally apply labels to the column names.  The
+        ``flat=True`` option will call :meth:`.FromClause.alias`
+        against the left and right sides individually.
+        Using this option, no new ``SELECT`` is produced;
+        we instead, from a construct as below::
+
+            j = table_a.join(table_b, table_a.c.id == table_b.c.a_id)
+            j = j.alias(flat=True)

+            table_a AS table_a_1 JOIN table_b AS table_b_1 ON
+            table_a_1.id = table_b_1.a_id
+
+        The ``flat=True`` argument is also propagated to the contained
+        selectables, so that a composite join such as::
+
+            j = table_a.join(
+                    table_b.join(table_c,
+                            table_b.c.id == table_c.c.b_id),
+                    table_b.c.a_id == table_a.c.id
+                ).alias(flat=True)

+            Due to a bug fix, this method has a slight
+            behavioral change as of version 0.7.3.
+            Prior to version 0.7.3, the FROM clause of
+            a :func:`.select` was calculated upfront and as new columns
+            were added; in 0.7.3 and later it's calculated
+            at compile time, fixing an issue regarding late binding
+            of columns to parent tables.  This changes the behavior of
+            :meth:`.Select.with_only_columns` in that FROM clauses no
+            longer represented in the new list are dropped,
+            but this behavior is more consistent in
+            that the FROM clauses are consistently derived from the
+            current columns clause.  The original intent of this method
+            is to allow trimming of the existing columns list to be fewer
+            columns than originally present; the use case of replacing
+            the columns list with an entirely different one hadn't
+            been anticipated until 0.7.3 was released; the usage
+            guidelines below illustrate how this should be done.
+
+        This method is exactly equivalent to as if the original
+        :func:`.select` had been called with the given columns
+        clause.   I.e. a statement::
+
+            s = select([table1.c.a, table1.c.b])
+            s = s.with_only_columns([table1.c.b])
+
+        should be exactly equivalent to::
+
+            s = select([table1.c.b])
+
+        This means that FROM clauses which are only derived
+        from the column list will be discarded if the new column
+        list no longer contains that FROM::
+
+            >>> table1 = table('t1', column('a'), column('b'))
+            >>> table2 = table('t2', column('a'), column('b'))
+            >>> s1 = select([table1.c.a, table2.c.b])
+            >>> print s1
+            SELECT t1.a, t2.b FROM t1, t2
+            >>> s2 = s1.with_only_columns([table2.c.b])
+            >>> print s2
+            SELECT t2.b FROM t1
+
+        The preferred way to maintain a specific FROM clause
+        in the construct, assuming it won't be represented anywhere
+        else (i.e. not in the WHERE clause, etc.) is to set it using
+        :meth:`.Select.select_from`::
+
+            >>> s1 = select([table1.c.a, table2.c.b]).\\
+            ...         select_from(table1.join(table2,
+            ...                 table1.c.a==table2.c.a))
+            >>> s2 = s1.with_only_columns([table2.c.b])
+            >>> print s2
+            SELECT t2.b FROM t1 JOIN t2 ON t1.a=t2.a
+
+        Care should also be taken to use the correct
+        set of column objects passed to :meth:`.Select.with_only_columns`.
+        Since the method is essentially equivalent to calling the
+        :func:`.select` construct in the first place with the given
+        columns, the columns passed to :meth:`.Select.with_only_columns`
+        should usually be a subset of those which were passed
+        to the :func:`.select` construct, not those which are available
+        from the ``.c`` collection of that :func:`.select`.  That
+        is::
+
+            s = select([table1.c.a, table1.c.b]).select_from(table1)
+            s = s.with_only_columns([table1.c.b])
+
+        and **not**::
+
+            # usually incorrect
+            s = s.with_only_columns([s.c.b])
+
+        The latter would produce the SQL::
+
+            SELECT b
+            FROM (SELECT t1.a AS a, t1.b AS b
+            FROM t1), t1
+
+        Since the :func:`.select` construct is essentially being
+        asked to select both from ``table1`` as well as itself.

+          requires that ``convert_unicode`` is set to ``force`` - otherwise,
+          SQLAlchemy is not guaranteed to handle the task of unicode
+          conversion.   Note that this flag adds significant performance
+          overhead to row-fetching operations for backends that already
+          return unicode objects natively (which most DBAPIs do).  This

+
+    The :class:`.Unicode` type is a :class:`.String` subclass
+    that assumes input and output as Python ``unicode`` data,
+    and in that regard is equivalent to the usage of the
+    ``convert_unicode`` flag with the :class:`.String` type.
+    However, unlike plain :class:`.String`, it also implies an
+    underlying column type that is explicitly supporting of non-ASCII
+    data, such as ``NVARCHAR`` on Oracle and SQL Server.
+    This can impact the output of ``CREATE TABLE`` statements
+    and ``CAST`` functions at the dialect level, and can
+    also affect the handling of bound parameters in some
+    specific DBAPI scenarios.
+
+    The encoding used by the :class:`.Unicode` type is usually
+    determined by the DBAPI itself; most modern DBAPIs
+    feature support for Python ``unicode`` objects as bound
+    values and result set values, and the encoding should
+    be configured as detailed in the notes for the target
+    DBAPI in the :ref:`dialect_toplevel` section.
+
+    For those DBAPIs which do not support, or are not configured
+    to accommodate Python ``unicode`` objects
+    directly, SQLAlchemy does the encoding and decoding
+    outside of the DBAPI.   The encoding in this scenario
+    is determined by the ``encoding`` flag passed to
+    :func:`.create_engine`.
+
+    When using the :class:`.Unicode` type, it is only appropriate
+    to pass Python ``unicode`` objects, and not plain ``str``.
+    If a plain ``str`` is passed under Python 2, a warning
+    is emitted.  If you notice your application emitting these warnings but
+    you're not sure of the source of them, the Python
+    ``warnings`` filter, documented at
+    http://docs.python.org/library/warnings.html,
+    can be used to turn these warnings into exceptions
+    which will illustrate a stack trace::
+
+      import warnings
+      warnings.simplefilter('error')
+
+    For an application that wishes to pass plain bytestrings
+    and Python ``unicode`` objects to the ``Unicode`` type
+    equally, the bytestrings must first be decoded into
+    unicode.  The recipe at :ref:`coerce_to_unicode` illustrates
+    how this is done.

+
+    The class-level "impl" attribute is required, and can reference any
+    TypeEngine class.  Alternatively, the load_dialect_impl() method
+    can be used to provide different type classes based on the dialect
+    given; in this case, the "impl" variable can reference
+    ``TypeEngine`` as a placeholder.
+
+    Types that receive a Python type that isn't similar to the ultimate type
+    used may want to define the :meth:`TypeDecorator.coerce_compared_value`
+    method. This is used to give the expression system a hint when coercing
+    Python objects into bind parameters within expressions. Consider this
+    expression::
+
+        mytable.c.somecol + datetime.date(2009, 5, 15)
+
+    Above, if "somecol" is an ``Integer`` variant, it makes sense that
+    we're doing date arithmetic, where above is usually interpreted
+    by databases as adding a number of days to the given date.
+    The expression system does the right thing by not attempting to
+    coerce the "date()" value into an integer-oriented bind parameter.
+
+    However, in the case of ``TypeDecorator``, we are usually changing an
+    incoming Python type to something new - ``TypeDecorator`` by default will
+    "coerce" the non-typed side to be the same type as itself. Such as below,
+    we define an "epoch" type that stores a date value as an integer::
+
+        class MyEpochType(types.TypeDecorator):
+            impl = types.Integer
+
+            epoch = datetime.date(1970, 1, 1)
+
+            def process_bind_param(self, value, dialect):
+                return (value - self.epoch).days
+
+            def process_result_value(self, value, dialect):
+                return self.epoch + timedelta(days=value)
+
+    Our expression of ``somecol + date`` with the above type will coerce the
+    "date" on the right side to also be treated as ``MyEpochType``.
+
+    This behavior can be overridden via the
+    :meth:`~TypeDecorator.coerce_compared_value` method, which returns a type
+    that should be used for the value of the expression. Below we set it such
+    that an integer value will be treated as an ``Integer``, and any other
+    value is assumed to be a date and will be treated as a ``MyEpochType``::
+
+        def coerce_compared_value(self, op, value):

+the visitor system is also used to inspect expressions for various
+information and patterns, as well as for usage in
+some kinds of expression transformation.  Other kinds of transformation
+use a non-visitor traversal system.
+
+For many examples of how the visit system is used, see the
+sqlalchemy.sql.util and the sqlalchemy.sql.compiler modules.

+Nose test runner module.
+
+This script is a front-end to "nosetests" which
+installs SQLAlchemy's testing plugin into the local environment.
+
+The script is intended to be used by third-party dialects and extensions
+that run within SQLAlchemy's testing framework.    The runner can
+be invoked via::
+
+    python -m sqlalchemy.testing.runner
+
+The script is then essentially the same as the "nosetests" script, including
+all of the usual Nose options.   The test environment requires that a
+setup.cfg is locally present including various required options.
+
+Note that when using this runner, Nose's "coverage" plugin will not be
+able to provide coverage for SQLAlchemy itself, since SQLAlchemy is
+imported into sys.modules before coverage is started.   The special
+script sqla_nose.py is provided as a top-level script which loads the
+plugin in a special (somewhat hacky) way so that coverage against
+SQLAlchemy itself is possible.

+"""Append module search paths for third-party packages to sys.path.
+
+****************************************************************
+* This module is automatically imported during initialization. *
+****************************************************************
+
+This will append site-specific paths to the module search path.  On
+Unix (including Mac OSX), it starts with sys.prefix and
+sys.exec_prefix (if different) and appends
+lib/python<version>/site-packages as well as lib/site-python.
+On other platforms (such as Windows), it tries each of the
+prefixes directly, as well as with lib/site-packages appended.  The
+resulting directories, if they exist, are appended to sys.path, and
+also inspected for path configuration files.
+
+If a file named "pyvenv.cfg" exists one directory above sys.executable,
+sys.prefix and sys.exec_prefix are set to that directory and
+it is also checked for site-packages and site-python (sys.base_prefix and
+sys.base_exec_prefix will always be the "real" prefixes of the Python
+installation). If "pyvenv.cfg" (a bootstrap configuration file) contains
+the key "include-system-site-packages" set to anything other than "false"
+(case-insensitive), the system-level prefixes will still also be
+searched for site-packages; otherwise they won't.
+
+All of the resulting site-specific directories, if they exist, are
+appended to sys.path, and also inspected for path configuration
+files.
+
+A path configuration file is a file whose name has the form
+<package>.pth; its contents are additional directories (one per line)
+to be added to sys.path.  Non-existing directories (or
+non-directories) are never added to sys.path; no directory is added to
+sys.path more than once.  Blank lines and lines beginning with
+'#' are skipped. Lines starting with 'import' are executed.
+
+For example, suppose sys.prefix and sys.exec_prefix are set to
+/usr/local and there is a directory /usr/local/lib/python2.5/site-packages
+with three subdirectories, foo, bar and spam, and two path
+configuration files, foo.pth and bar.pth.  Assume foo.pth contains the
+following:
+
+  # foo package configuration
+  foo
+  bar
+  bletch
+
+and bar.pth contains:
+
+  # bar package configuration
+  bar
+
+Then the following directories are added to sys.path, in this order:
+
+  /usr/local/lib/python2.5/site-packages/bar
+  /usr/local/lib/python2.5/site-packages/foo
+
+Note that bletch is omitted because it doesn't exist; bar precedes foo
+because bar.pth comes alphabetically before foo.pth; and spam is
+omitted because it is not mentioned in either path configuration file.
+
+The readline module is also automatically configured to enable
+completion for systems that support it.  This can be overriden in
+sitecustomize, usercustomize or PYTHONSTARTUP.
+
+After these operations, an attempt is made to import a module
+named sitecustomize, which can perform arbitrary additional
+site-specific customizations.  If this import fails with an
+ImportError exception, it is silently ignored.

+# Overview:
+#
+# This file implements the minimal SMTP protocol as defined in RFC 5321.  It
+# has a hierarchy of classes which implement the backend functionality for the
+# smtpd.  A number of classes are provided:
+#
+#   SMTPServer - the base class for the backend.  Raises NotImplementedError
+#   if you try to use it.
+#
+#   DebuggingServer - simply prints each message it receives on stdout.
+#
+#   PureProxy - Proxies all messages to a real smtpd which does final
+#   delivery.  One known problem with this class is that it doesn't handle
+#   SMTP errors from the backend server at all.  This should be fixed
+#   (contributions are welcome!).
+#
+#   MailmanProxy - An experimental hack to work with GNU Mailman
+#   <www.list.org>.  Using this server as your real incoming smtpd, your
+#   mailhost will automatically recognize and accept mail destined to Mailman
+#   lists when those lists are created.  Every message not destined for a list
+#   gets forwarded to a real backend smtpd, as with PureProxy.  Again, errors
+#   are not handled correctly yet.
+#

+Function whathdr() recognizes various types of sound file headers.
+It understands almost all headers that SOX can decode.
+
+The return tuple contains the following items, in this order:
+- file type (as SOX understands it)
+- sampling rate (0 if unknown or hard to decode)
+- number of channels (0 if unknown or hard to decode)
+- number of frames in the file (-1 if unknown or hard to decode)
+- number of bits/sample, or 'U' for U-LAW, or 'A' for A-LAW
+
+If the file doesn't have a recognizable type, it returns None.
+If the file can't be opened, OSError is raised.
+
+To compute the total time, divide the number of frames by the
+sampling rate (a frame contains a sample for each channel).
+
+Function what() calls whathdr().  (It used to also use some
+heuristics for raw data, but this doesn't work very well.)
+
+Finally, the function test() is a simple main program that calls
+what() for all files mentioned on the argument list.  For directory
+arguments it calls what() for all files in that directory.  Default
+argument is "." (testing all files in the current directory).  The

+# Wrapper module for _socket, providing some additional facilities
+# implemented in Python.
+
+"""\
+This module provides socket operations and some related functions.
+On Unix, it supports IP (Internet Protocol) and Unix domain sockets.
+On other systems, it only supports IP. Functions specific for a
+socket are available as methods of the socket object.
+
+Functions:
+
+socket() -- create a new socket object
+socketpair() -- create a pair of new socket objects [*]
+fromfd() -- create a socket object from an open file descriptor [*]
+fromshare() -- create a socket object from data received from socket.share() [*]
+gethostname() -- return the current hostname
+gethostbyname() -- map a hostname to its IP number
+gethostbyaddr() -- map an IP number or hostname to DNS info
+getservbyname() -- map a service name and a protocol name to a port number
+getprotobyname() -- map a protocol name (e.g. 'tcp') to a number
+ntohs(), ntohl() -- convert 16, 32 bit int from network to host byte order
+htons(), htonl() -- convert 16, 32 bit int from host to network byte order
+inet_aton() -- convert IP addr string (123.45.67.89) to 32-bit packed format
+inet_ntoa() -- convert 32-bit packed format IP to string (123.45.67.89)
+socket.getdefaulttimeout() -- get the default timeout value
+socket.setdefaulttimeout() -- set the default timeout value
+create_connection() -- connects to an address, with an optional timeout and
+                       optional source address.
+
+ [*] not available on all platforms!
+
+Special objects:
+
+SocketType -- type object for socket objects
+error -- exception raised for I/O errors
+has_ipv6 -- boolean value indicating if IPv6 is supported
+
+Integer constants:
+
+AF_INET, AF_UNIX -- socket domains (first argument to socket() call)
+SOCK_STREAM, SOCK_DGRAM, SOCK_RAW -- socket types (second argument)
+
+Many other constants may be defined; these may be used in calls to
+the setsockopt() and getsockopt() methods.

+"""Generic socket server classes.
+
+This module tries to capture the various aspects of defining a server:
+
+For socket-based servers:
+
+- address family:
+        - AF_INET{,6}: IP (Internet Protocol) sockets (default)
+        - AF_UNIX: Unix domain sockets
+        - others, e.g. AF_DECNET are conceivable (see <socket.h>
+- socket type:
+        - SOCK_STREAM (reliable stream, e.g. TCP)
+        - SOCK_DGRAM (datagrams, e.g. UDP)
+
+For request-based servers (including socket-based):
+
+- client address verification before further looking at the request
+        (This is actually a hook for any processing that needs to look
+         at the request before anything else, e.g. logging)
+- how to handle multiple requests:
+        - synchronous (one request is handled at a time)
+        - forking (each request is handled by a new process)
+        - threading (each request is handled by a new thread)
+
+The classes in this module favor the server type that is simplest to
+write: a synchronous TCP/IP server.  This is bad class design, but
+save some typing.  (There's also the issue that a deep class hierarchy
+slows down method lookups.)
+
+There are five classes in an inheritance diagram, four of which represent
+synchronous servers of four types:
+
+        +------------+
+        | BaseServer |
+        +------------+
+              |
+              v
+        +-----------+        +------------------+
+        | TCPServer |------->| UnixStreamServer |
+        +-----------+        +------------------+
+              |
+              v
+        +-----------+        +--------------------+
+        | UDPServer |------->| UnixDatagramServer |
+        +-----------+        +--------------------+
+
+Note that UnixDatagramServer derives from UDPServer, not from
+UnixStreamServer -- the only difference between an IP and a Unix
+stream server is the address family, which is simply repeated in both
+unix server classes.
+
+Forking and threading versions of each type of server can be created
+using the ForkingMixIn and ThreadingMixIn mix-in classes.  For
+instance, a threading UDP server class is created as follows:
+
+        class ThreadingUDPServer(ThreadingMixIn, UDPServer): pass
+
+The Mix-in class must come first, since it overrides a method defined
+in UDPServer! Setting the various member variables also changes
+the behavior of the underlying server mechanism.
+
+To implement a service, you must derive a class from
+BaseRequestHandler and redefine its handle() method.  You can then run
+various versions of the service by combining one of the server classes
+with your request handler class.
+
+The request handler class must be different for datagram or stream
+services.  This can be hidden by using the request handler
+subclasses StreamRequestHandler or DatagramRequestHandler.
+
+Of course, you still have to use your head!
+
+For instance, it makes no sense to use a forking server if the service
+contains state in memory that can be modified by requests (since the
+modifications in the child process would never reach the initial state
+kept in the parent process and passed to each child).  In this case,
+you can use a threading server, but you will probably have to use
+locks to avoid two requests that come in nearly simultaneous to apply
+conflicting changes to the server state.
+
+On the other hand, if you are building e.g. an HTTP server, where all
+data is stored externally (e.g. in the file system), a synchronous
+class will essentially render the service "deaf" while one request is
+being handled -- which may be for a very long time if a client is slow
+to read all the data it has requested.  Here a threading or forking
+server is appropriate.
+
+In some cases, it may be appropriate to process part of a request
+synchronously, but to finish processing in a forked child depending on
+the request data.  This can be implemented by using a synchronous
+server and doing an explicit fork in the request handler class
+handle() method.
+
+Another approach to handling multiple simultaneous requests in an
+environment that supports neither threads nor fork (or where these are
+too expensive or inappropriate for the service) is to maintain an
+explicit table of partially finished requests and to use select() to
+decide which request to work on next (or whether to handle a new
+incoming request).  This is particularly important for stream services
+where each client can potentially be connected for a long time (if
+threads or subprocesses cannot be used).
+
+Future work:
+- Standard classes for Sun RPC (which uses either UDP or TCP)
+- Standard mix-in classes to implement various authentication
+  and encryption schemes
+- Standard framework for select-based multiplexing
+
+XXX Open problems:
+- What to do with out-of-band data?
+
+BaseServer:
+- split generic "request" functionality out into BaseServer class.

+# Wrapper module for _ssl, providing some additional facilities
+# implemented in Python.  Written by Bill Janssen.
+
+"""This module provides some more Pythonic support for SSL.
+
+Object types:
+
+  SSLSocket -- subtype of socket.socket which does SSL over the socket
+
+Exceptions:
+
+  SSLError -- exception raised for I/O errors
+
+Functions:
+
+  cert_time_to_seconds -- convert time string used for certificate
+                          notBefore and notAfter functions to integer
+                          seconds past the Epoch (the time values
+                          returned from time.time())
+
+  fetch_server_certificate (HOST, PORT) -- fetch the certificate provided
+                          by the server running on HOST at port PORT.  No
+                          validation of the certificate is performed.
+
+Integer constants:
+
+SSL_ERROR_ZERO_RETURN
+SSL_ERROR_WANT_READ
+SSL_ERROR_WANT_WRITE
+SSL_ERROR_WANT_X509_LOOKUP
+SSL_ERROR_SYSCALL
+SSL_ERROR_SSL
+SSL_ERROR_WANT_CONNECT
+
+SSL_ERROR_EOF
+SSL_ERROR_INVALID_ERROR_CODE
+
+The following group define certificate requirements that one side is
+allowing/requiring from the other side:
+
+CERT_NONE - no certificates from the other side are required (or will
+            be looked at if provided)
+CERT_OPTIONAL - certificates are not required, but if provided will be
+                validated, and if validation fails, the connection will
+                also fail
+CERT_REQUIRED - certificates are required, and will be validated, and
+                if validation fails, the connection will also fail
+
+The following constants identify various SSL protocol variants:
+
+PROTOCOL_SSLv2
+PROTOCOL_SSLv3
+PROTOCOL_SSLv23
+PROTOCOL_TLSv1
+PROTOCOL_TLSv1_1
+PROTOCOL_TLSv1_2
+
+The following constants identify various SSL alert message descriptions as per
+http://www.iana.org/assignments/tls-parameters/tls-parameters.xml#tls-parameters-6
+
+ALERT_DESCRIPTION_CLOSE_NOTIFY
+ALERT_DESCRIPTION_UNEXPECTED_MESSAGE

+Basic statistics module.
+
+This module provides functions for calculating statistics of data, including
+averages, variance, and standard deviation.
+
+Calculating averages
+--------------------
+
+==================  =============================================
+Function            Description
+==================  =============================================
+mean                Arithmetic mean (average) of data.
+median              Median (middle value) of data.
+median_low          Low median of data.
+median_high         High median of data.
+median_grouped      Median, or 50th percentile, of grouped data.
+mode                Mode (most common value) of data.
+==================  =============================================
+
+Calculate the arithmetic mean ("the average") of data:
+
+>>> mean([-1.0, 2.5, 3.25, 5.75])
+2.625
+
+
+Calculate the standard median of discrete data:
+
+>>> median([2, 3, 4, 5])
+3.5
+
+
+Calculate the median, or 50th percentile, of data grouped into class intervals
+centred on the data values provided. E.g. if your data points are rounded to
+the nearest whole number:
+
+>>> median_grouped([2, 2, 3, 3, 3, 4])  #doctest: +ELLIPSIS
+2.8333333333...
+
+This should be interpreted in this way: you have two data points in the class
+interval 1.5-2.5, three data points in the class interval 2.5-3.5, and one in
+the class interval 3.5-4.5. The median of these data points is 2.8333...
+
+
+Calculating variability or spread
+---------------------------------
+
+==================  =============================================
+Function            Description
+==================  =============================================
+pvariance           Population variance of data.
+variance            Sample variance of data.
+pstdev              Population standard deviation of data.
+stdev               Sample standard deviation of data.
+==================  =============================================
+
+Calculate the standard deviation of sample data:
+
+>>> stdev([2.5, 3.25, 5.5, 11.25, 11.75])  #doctest: +ELLIPSIS
+4.38961843444...
+
+If you have previously calculated the mean, you can pass it as the optional
+second argument to the four "spread" functions to avoid recalculating it:
+
+>>> data = [1, 2, 2, 4, 4, 4, 5, 6]
+>>> mu = mean(data)
+>>> pvariance(data, mu)
+2.5
+

+Exceptions

+A single exception is defined: StatisticsError is a subclass of ValueError.

+r"""subprocess - Subprocesses with accessible I/O streams
+
+This module allows you to spawn processes, connect to their
+input/output/error pipes, and obtain their return codes.  This module
+intends to replace several older modules and functions:
+
+os.system
+os.spawn*
+
+Information about how the subprocess module can be used to replace these
+modules and functions can be found below.
+
+
+
+Using the subprocess module
+===========================
+This module defines one class called Popen:
+
+class Popen(args, bufsize=-1, executable=None,
+            stdin=None, stdout=None, stderr=None,
+            preexec_fn=None, close_fds=True, shell=False,
+            cwd=None, env=None, universal_newlines=False,
+            startupinfo=None, creationflags=0,
+            restore_signals=True, start_new_session=False, pass_fds=()):
+
+
+Arguments are:
+
+args should be a string, or a sequence of program arguments.  The
+program to execute is normally the first item in the args sequence or
+string, but can be explicitly set by using the executable argument.
+
+On POSIX, with shell=False (default): In this case, the Popen class
+uses os.execvp() to execute the child program.  args should normally
+be a sequence.  A string will be treated as a sequence with the string
+as the only item (the program to execute).
+
+On POSIX, with shell=True: If args is a string, it specifies the
+command string to execute through the shell.  If args is a sequence,
+the first item specifies the command string, and any additional items
+will be treated as additional shell arguments.
+
+On Windows: the Popen class uses CreateProcess() to execute the child
+program, which operates on strings.  If args is a sequence, it will be
+converted to a string using the list2cmdline method.  Please note that
+not all MS Windows applications interpret the command line the same
+way: The list2cmdline is designed for applications using the same
+rules as the MS C runtime.
+
+bufsize will be supplied as the corresponding argument to the io.open()
+function when creating the stdin/stdout/stderr pipe file objects:
+0 means unbuffered (read & write are one system call and can return short),
+1 means line buffered, any other positive value means use a buffer of
+approximately that size.  A negative bufsize, the default, means the system
+default of io.DEFAULT_BUFFER_SIZE will be used.
+
+stdin, stdout and stderr specify the executed programs' standard
+input, standard output and standard error file handles, respectively.
+Valid values are PIPE, an existing file descriptor (a positive
+integer), an existing file object, and None.  PIPE indicates that a
+new pipe to the child should be created.  With None, no redirection
+will occur; the child's file handles will be inherited from the
+parent.  Additionally, stderr can be STDOUT, which indicates that the
+stderr data from the applications should be captured into the same
+file handle as for stdout.
+
+On POSIX, if preexec_fn is set to a callable object, this object will be
+called in the child process just before the child is executed.  The use
+of preexec_fn is not thread safe, using it in the presence of threads
+could lead to a deadlock in the child process before the new executable
+is executed.
+
+If close_fds is true, all file descriptors except 0, 1 and 2 will be
+closed before the child process is executed.  The default for close_fds
+varies by platform:  Always true on POSIX.  True when stdin/stdout/stderr
+are None on Windows, false otherwise.
+
+pass_fds is an optional sequence of file descriptors to keep open between the
+parent and child.  Providing any pass_fds implicitly sets close_fds to true.
+
+if shell is true, the specified command will be executed through the
+shell.
+
+If cwd is not None, the current directory will be changed to cwd
+before the child is executed.
+
+On POSIX, if restore_signals is True all signals that Python sets to
+SIG_IGN are restored to SIG_DFL in the child process before the exec.
+Currently this includes the SIGPIPE, SIGXFZ and SIGXFSZ signals.  This
+parameter does nothing on Windows.
+
+On POSIX, if start_new_session is True, the setsid() system call will be made
+in the child process prior to executing the command.
+
+If env is not None, it defines the environment variables for the new
+process.
+
+If universal_newlines is false, the file objects stdin, stdout and stderr
+are opened as binary files, and no line ending conversion is done.
+
+If universal_newlines is true, the file objects stdout and stderr are
+opened as a text files, but lines may be terminated by any of '\n',
+the Unix end-of-line convention, '\r', the old Macintosh convention or
+'\r\n', the Windows convention.  All of these external representations
+are seen as '\n' by the Python program.  Also, the newlines attribute
+of the file objects stdout, stdin and stderr are not updated by the
+communicate() method.
+
+The startupinfo and creationflags, if given, will be passed to the
+underlying CreateProcess() function.  They can specify things such as
+appearance of the main window and priority for the new process.
+(Windows only)
+
+
+This module also defines some shortcut functions:
+
+call(*popenargs, **kwargs):
+    Run command with arguments.  Wait for command to complete, then
+    return the returncode attribute.
+
+    The arguments are the same as for the Popen constructor.  Example:
+
+    >>> retcode = subprocess.call(["ls", "-l"])
+
+check_call(*popenargs, **kwargs):
+    Run command with arguments.  Wait for command to complete.  If the
+    exit code was zero then return, otherwise raise
+    CalledProcessError.  The CalledProcessError object will have the
+    return code in the returncode attribute.
+
+    The arguments are the same as for the Popen constructor.  Example:
+
+    >>> subprocess.check_call(["ls", "-l"])
+    0
+
+getstatusoutput(cmd):
+    Return (status, output) of executing cmd in a shell.
+
+    Execute the string 'cmd' in a shell with 'check_output' and
+    return a 2-tuple (status, output). Universal newlines mode is used,
+    meaning that the result with be decoded to a string.
+
+    A trailing newline is stripped from the output.
+    The exit status for the command can be interpreted
+    according to the rules for the function 'wait'.  Example:
+
+    >>> subprocess.getstatusoutput('ls /bin/ls')
+    (0, '/bin/ls')
+    >>> subprocess.getstatusoutput('cat /bin/junk')
+    (256, 'cat: /bin/junk: No such file or directory')
+    >>> subprocess.getstatusoutput('/bin/junk')
+    (256, 'sh: /bin/junk: not found')
+
+getoutput(cmd):
+    Return output (stdout or stderr) of executing cmd in a shell.
+
+    Like getstatusoutput(), except the exit status is ignored and the return
+    value is a string containing the command's output.  Example:
+
+    >>> subprocess.getoutput('ls /bin/ls')
+    '/bin/ls'
+
+check_output(*popenargs, **kwargs):
+    Run command with arguments and return its output.
+
+    If the exit code was non-zero it raises a CalledProcessError.  The
+    CalledProcessError object will have the return code in the returncode
+    attribute and output in the output attribute.
+
+    The arguments are the same as for the Popen constructor.  Example:
+
+    >>> output = subprocess.check_output(["ls", "-l", "/dev/null"])
+
+    There is an additional optional argument, "input", allowing you to
+    pass a string to the subprocess's stdin.  If you use this argument
+    you may not also use the Popen constructor's "stdin" argument.
+
+Exceptions
+----------
+Exceptions raised in the child process, before the new program has
+started to execute, will be re-raised in the parent.  Additionally,
+the exception object will have one extra attribute called
+'child_traceback', which is a string containing traceback information
+from the child's point of view.
+
+The most common exception raised is OSError.  This occurs, for
+example, when trying to execute a non-existent file.  Applications
+should prepare for OSErrors.
+
+A ValueError will be raised if Popen is called with invalid arguments.
+
+Exceptions defined within this module inherit from SubprocessError.
+check_call() and check_output() will raise CalledProcessError if the
+called process returns a non-zero return code.  TimeoutExpired
+be raised if a timeout was specified and expired.
+
+
+Security
+--------
+Unlike some other popen functions, this implementation will never call
+/bin/sh implicitly.  This means that all characters, including shell
+metacharacters, can safely be passed to child processes.
+
+
+Popen objects
+=============
+Instances of the Popen class have the following methods:
+
+poll()
+    Check if child process has terminated.  Returns returncode
+    attribute.
+
+wait()
+    Wait for child process to terminate.  Returns returncode attribute.
+
+communicate(input=None)
+    Interact with process: Send data to stdin.  Read data from stdout
+    and stderr, until end-of-file is reached.  Wait for process to
+    terminate.  The optional input argument should be a string to be
+    sent to the child process, or None, if no data should be sent to
+    the child.
+
+    communicate() returns a tuple (stdout, stderr).
+
+    Note: The data read is buffered in memory, so do not use this
+    method if the data size is large or unlimited.
+
+The following attributes are also available:
+
+stdin
+    If the stdin argument is PIPE, this attribute is a file object
+    that provides input to the child process.  Otherwise, it is None.
+
+stdout
+    If the stdout argument is PIPE, this attribute is a file object
+    that provides output from the child process.  Otherwise, it is
+    None.
+
+stderr
+    If the stderr argument is PIPE, this attribute is file object that
+    provides error output from the child process.  Otherwise, it is
+    None.
+
+pid
+    The process ID of the child process.
+
+returncode
+    The child return code.  A None value indicates that the process
+    hasn't terminated yet.  A negative value -N indicates that the
+    child was terminated by signal N (POSIX only).
+
+
+Replacing older functions with the subprocess module
+====================================================
+In this section, "a ==> b" means that b can be used as a replacement
+for a.
+
+Note: All functions in this section fail (more or less) silently if
+the executed program cannot be found; this module raises an OSError
+exception.
+
+In the following examples, we assume that the subprocess module is
+imported with "from subprocess import *".
+
+
+Replacing /bin/sh shell backquote
+---------------------------------
+output=`mycmd myarg`
+==>
+output = Popen(["mycmd", "myarg"], stdout=PIPE).communicate()[0]
+
+
+Replacing shell pipe line
+-------------------------
+output=`dmesg | grep hda`
+==>
+p1 = Popen(["dmesg"], stdout=PIPE)
+p2 = Popen(["grep", "hda"], stdin=p1.stdout, stdout=PIPE)
+output = p2.communicate()[0]
+
+
+Replacing os.system()
+---------------------
+sts = os.system("mycmd" + " myarg")
+==>
+p = Popen("mycmd" + " myarg", shell=True)
+pid, sts = os.waitpid(p.pid, 0)
+
+Note:
+
+* Calling the program through the shell is usually not required.
+
+* It's easier to look at the returncode attribute than the
+  exitstatus.
+
+A more real-world example would look like this:
+
+try:
+    retcode = call("mycmd" + " myarg", shell=True)
+    if retcode < 0:
+        print("Child was terminated by signal", -retcode, file=sys.stderr)
+    else:
+        print("Child returned", retcode, file=sys.stderr)
+except OSError as e:
+    print("Execution failed:", e, file=sys.stderr)
+
+
+Replacing os.spawn*
+-------------------
+P_NOWAIT example:
+
+pid = os.spawnlp(os.P_NOWAIT, "/bin/mycmd", "mycmd", "myarg")
+==>
+pid = Popen(["/bin/mycmd", "myarg"]).pid
+
+
+P_WAIT example:
+
+retcode = os.spawnlp(os.P_WAIT, "/bin/mycmd", "mycmd", "myarg")
+==>
+retcode = call(["/bin/mycmd", "myarg"])
+
+
+Vector example:
+
+os.spawnvp(os.P_NOWAIT, path, args)
+==>
+Popen([path] + args[1:])
+
+
+Environment example:
+
+os.spawnlpe(os.P_NOWAIT, "/bin/mycmd", "mycmd", "myarg", env)
+==>
+Popen(["/bin/mycmd", "myarg"], env={"PATH": "/usr/bin"})

+r"""TELNET client class.
+
+Based on RFC 854: TELNET Protocol Specification, by J. Postel and
+J. Reynolds
+
+Example:
+
+>>> from telnetlib import Telnet
+>>> tn = Telnet('www.python.org', 79)   # connect to finger port
+>>> tn.write(b'guido\r\n')
+>>> print(tn.read_all())

+guido    Guido van Rossum      pts/2        <Dec  2 11:10> snag.cnri.reston..
+
+>>>
+
+Note that read_all() won't read until eof -- it just reads some data
+-- but it guarantees to read at least one byte unless EOF is hit.
+
+It is possible to pass a Telnet object to a selector in order to wait until
+more data is available.  Note that in this case, read_eager() may return b''
+even if there was data on the socket, because the protocol negotiation may have
+eaten the data.  This is why EOFError is needed in some cases to distinguish
+between "no data" and "connection closed" (since the socket also appears ready
+for reading when it is closed).
+
+To do:
+- option negotiation
+- timeout should be intrinsic to the connection object instead of an
+  option on one of the read calls only

+
+    An instance of this class represents a connection to a telnet
+    server.  The instance is initially not connected; the open()
+    method must be used to establish a connection.  Alternatively, the
+    host name and optional port number can be passed to the
+    constructor, too.
+
+    Don't try to reopen an already connected instance.
+
+    This class has many read_*() methods.  Note that some of them
+    raise EOFError when the end of the connection is read, because
+    they can return an empty string for other reasons.  See the
+    individual doc strings.
+
+    read_until(expected, [timeout])
+        Read until the expected string has been seen, or a timeout is
+        hit (default is no timeout); may block.
+
+    read_all()
+        Read all data until EOF; may block.
+
+    read_some()
+        Read at least one byte or EOF; may block.
+
+    read_very_eager()
+        Read all data available already queued or on the socket,
+        without blocking.
+
+    read_eager()
+        Read either data already queued or some data available on the
+        socket, without blocking.
+
+    read_lazy()
+        Read all data in the raw queue (processing it first), without
+        doing any socket I/O.

+    read_very_lazy()
+        Reads all data in the cooked queue, without doing any socket

-The difference in default timer function is because on Windows,
-clock() has microsecond granularity but time()'s granularity is 1/60th
-of a second; on Unix, clock() has 1/100th of a second granularity and
-time() is much more precise.  On either platform, the default timer
-functions measure wall clock time, not the CPU time.  This means that
-other processes running on the same computer may interfere with the
-timing.  The best thing to do when accurate timing is necessary is to
-repeat the timing a few times and use the best time.  The -r option is
-good for this; the default of 3 repetitions is probably enough in most
-cases.  On Unix, you can use clock() to measure CPU time.

+            Specify a height for the window. The height will be the
+            outer dimension of the window including its border, if
+            any. If size is an empty string, or if -height is not
+            specified, then the height requested internally by the

+            adjusted by the movement of sashes in the panedwindow.
+            Size may be any value accepted by Tk_GetPixels.
+        minsize n
+            Specifies that the size of the window cannot be made
+            less than n. This constraint only affects the size of

+            for horizontal panedwindows, the y dimension for
+            vertical panedwindows. May be any value accepted by
+            Tk_GetPixels.
+        padx n
+            Specifies a non-negative value indicating how much
+            extra space to leave on each side of the window in
+            the X-direction. The value may have any of the forms
+            accepted by Tk_GetPixels.
+        pady n
+            Specifies a non-negative value indicating how much

+        sticky style
+            If a window's pane is larger than the requested
+            dimensions of the window, this option may be used
+            to position (or stretch) the window within its pane.
+            Style is a string that contains zero or more of the
+            characters n, s, e or w. The string can optionally
+            contains spaces or commas, but they are ignored. Each
+            letter refers to a side (north, south, east, or west)
+            that the window will "stick" to. If both n and s

+            stretched to fill the entire height (or width) of
+            its cavity.
+        width size
+            Specify a width for the window. The width will be
+            the outer dimension of the window including its
+            border, if any. If size is an empty string, or
+            if -width is not specified, then the width requested

+"""Drag-and-drop support for Tkinter.
+
+This is very preliminary.  I currently only support dnd *within* one
+application, between different windows (or within the same window).
+
+I an trying to make this as generic as possible -- not dependent on
+the use of a particular widget or icon type, etc.  I also hope that
+this will work with Pmw.
+
+To enable an object to be dragged, you must create an event binding
+for it that starts the drag-and-drop process. Typically, you should
+bind <ButtonPress> to a callback function that you write. The function
+should call Tkdnd.dnd_start(source, event), where 'source' is the
+object to be dragged, and 'event' is the event that invoked the call
+(the argument to your callback function).  Even though this is a class
+instantiation, the returned instance should not be stored -- it will
+be kept alive automatically for the duration of the drag-and-drop.
+
+When a drag-and-drop is already in process for the Tk interpreter, the
+call is *ignored*; this normally averts starting multiple simultaneous
+dnd processes, e.g. because different button callbacks all
+dnd_start().
+
+The object is *not* necessarily a widget -- it can be any
+application-specific object that is meaningful to potential
+drag-and-drop targets.
+
+Potential drag-and-drop targets are discovered as follows.  Whenever
+the mouse moves, and at the start and end of a drag-and-drop move, the
+Tk widget directly under the mouse is inspected.  This is the target
+widget (not to be confused with the target object, yet to be
+determined).  If there is no target widget, there is no dnd target
+object.  If there is a target widget, and it has an attribute
+dnd_accept, this should be a function (or any callable object).  The
+function is called as dnd_accept(source, event), where 'source' is the
+object being dragged (the object passed to dnd_start() above), and
+'event' is the most recent event object (generally a <Motion> event;
+it can also be <ButtonPress> or <ButtonRelease>).  If the dnd_accept()
+function returns something other than None, this is the new dnd target
+object.  If dnd_accept() returns None, or if the target widget has no
+dnd_accept attribute, the target widget's parent is considered as the
+target widget, and the search for a target object is repeated from
+there.  If necessary, the search is repeated all the way up to the
+root widget.  If none of the target widgets can produce a target
+object, there is no target object (the target object is None).
+
+The target object thus produced, if any, is called the new target
+object.  It is compared with the old target object (or None, if there
+was no old target widget).  There are several cases ('source' is the
+source object, and 'event' is the most recent event object):
+
+- Both the old and new target objects are None.  Nothing happens.
+
+- The old and new target objects are the same object.  Its method
+dnd_motion(source, event) is called.
+
+- The old target object was None, and the new target object is not
+None.  The new target object's method dnd_enter(source, event) is
+called.
+
+- The new target object is None, and the old target object is not
+None.  The old target object's method dnd_leave(source, event) is
+called.
+
+- The old and new target objects differ and neither is None.  The old
+target object's method dnd_leave(source, event), and then the new
+target object's method dnd_enter(source, event) is called.
+
+Once this is done, the new target object replaces the old one, and the
+Tk mainloop proceeds.  The return value of the methods mentioned above
+is ignored; if they raise an exception, the normal exception handling
+mechanisms take over.
+
+The drag-and-drop processes can end in two ways: a final target object
+is selected, or no final target object is selected.  When a final
+target object is selected, it will always have been notified of the
+potential drop by a call to its dnd_enter() method, as described
+above, and possibly one or more calls to its dnd_motion() method; its
+dnd_leave() method has not been called since the last call to
+dnd_enter().  The target is notified of the drop by a call to its
+method dnd_commit(source, event).
+
+If no final target object is selected, and there was an old target
+object, its dnd_leave(source, event) method is called to complete the
+dnd sequence.
+
+Finally, the source object is notified that the drag-and-drop process
+is over, by a call to source.dnd_end(target, event), specifying either
+the selected target object, or None if no target object was selected.
+The source object can use this to implement the commit action; this is
+sometimes simpler than to do it in the target's dnd_commit().  The
+target's dnd_commit() method could then simply be aliased to
+dnd_leave().
+
+At any time during a dnd sequence, the application can cancel the
+sequence by calling the cancel() method on the object returned by
+dnd_start().  This will call dnd_leave() if a target is currently
+active; it will never call dnd_commit().

+"""Tokenization help for Python programs.
+
+tokenize(readline) is a generator that breaks a stream of bytes into
+Python tokens.  It decodes the bytes according to PEP-0263 for
+determining source file encoding.
+
+It accepts a readline-like method which is called repeatedly to get the
+next line of input (or b"" for EOF).  It generates 5-tuples with these
+members:
+
+    the token type (see token.py)
+    the token (a string)
+    the starting (row, column) indices of the token (a 2-tuple of ints)
+    the ending (row, column) indices of the token (a 2-tuple of ints)
+    the original line (string)
+
+It is designed to match the working of the Python tokenizer exactly, except
+that it produces COMMENT tokens for comments and gives type OP for all
+operators.  Additionally, all token lists start with an ENCODING token
+which tells you which encoding was used to decode the bytes stream.

+========================================================
+    A new turtle module for Python
+========================================================
+
+Turtle graphics is a popular way for introducing programming to
+kids. It was part of the original Logo programming language developed
+by Wally Feurzig and Seymour Papert in 1966.
+
+Imagine a robotic turtle starting at (0, 0) in the x-y plane. After an ``import turtle``, give it
+the command turtle.forward(15), and it moves (on-screen!) 15 pixels in
+the direction it is facing, drawing a line as it moves. Give it the
+command turtle.right(25), and it rotates in-place 25 degrees clockwise.
+
+By combining together these and similar commands, intricate shapes and
+pictures can easily be drawn.
+
+----- turtle.py
+
+This module is an extended reimplementation of turtle.py from the
+Python standard distribution up to Python 2.5. (See: http:\\www.python.org)
+
+It tries to keep the merits of turtle.py and to be (nearly) 100%
+compatible with it. This means in the first place to enable the
+learning programmer to use all the commands, classes and methods
+interactively when using the module from within IDLE run with
+the -n switch.
+
+Roughly it has the following features added:
+
+- Better animation of the turtle movements, especially of turning the
+    turtle. So the turtles can more easily be used as a visual feedback
+    instrument by the (beginning) programmer.
+
+- Different turtle shapes, gif-images as turtle shapes, user defined
+    and user controllable turtle shapes, among them compound
+    (multicolored) shapes. Turtle shapes can be stgretched and tilted, which
+    makes turtles zu very versatile geometrical objects.
+
+- Fine control over turtle movement and screen updates via delay(),
+    and enhanced tracer() and speed() methods.
+
+- Aliases for the most commonly used commands, like fd for forward etc.,
+    following the early Logo traditions. This reduces the boring work of
+    typing long sequences of commands, which often occur in a natural way
+    when kids try to program fancy pictures on their first encounter with
+    turtle graphcis.
+
+- Turtles now have an undo()-method with configurable undo-buffer.
+
+- Some simple commands/methods for creating event driven programs
+    (mouse-, key-, timer-events). Especially useful for programming games.
+
+- A scrollable Canvas class. The default scrollable Canvas can be
+    extended interactively as needed while playing around with the turtle(s).
+
+- A TurtleScreen class with methods controlling background color or
+    background image, window and canvas size and other properties of the
+    TurtleScreen.
+
+- There is a method, setworldcoordinates(), to install a user defined
+    coordinate-system for the TurtleScreen.
+
+- The implementation uses a 2-vector class named Vec2D, derived from tuple.
+    This class is public, so it can be imported by the application programmer,
+    which makes certain types of computations very natural and compact.
+
+- Appearance of the TurtleScreen and the Turtles at startup/import can be
+    configured by means of a turtle.cfg configuration file.
+    The default configuration mimics the appearance of the old turtle module.
+
+- If configured appropriately the module reads in docstrings from a docstring
+    dictionary in some different language, supplied separately  and replaces
+    the english ones by those read in. There is a utility function
+    write_docstringdict() to write a dictionary with the original (english)
+    docstrings to disc, so it can serve as a template for translations.

+  ----------------------------------------------
+
+      turtleDemo - Help
+
+  ----------------------------------------------
+
+  This document has two sections:
+
+  (1) How to use the demo viewer
+  (2) How to add your own demos to the demo repository
+
+
+  (1) How to use the demo viewer.
+
+  Select a demoscript from the example menu.
+  The (syntax coloured) source code appears in the left
+  source code window. IT CANNOT BE EDITED, but ONLY VIEWED!
+
+  - Press START button to start the demo.
+  - Stop execution by pressing the STOP button.
+  - Clear screen by pressing the CLEAR button.
+  - Restart by pressing the START button again.
+
+  SPECIAL demos are those which run EVENTDRIVEN.
+  (For example clock.py - or oldTurtleDemo.py which
+  in the end expects a mouse click.):
+
+      Press START button to start the demo.
+
+      - Until the EVENTLOOP is entered everything works
+      as in an ordinary demo script.
+
+      - When the EVENTLOOP is entered, you control the
+      application by using the mouse and/or keys (or it's
+      controlled by some timer events)
+      To stop it you can and must press the STOP button.
+
+      While the EVENTLOOP is running, the examples menu is disabled.
+
+      - Only after having pressed the STOP button, you may
+      restart it or choose another example script.
+
+   * * * * * * * *
+   In some rare situations there may occur interferences/conflicts
+   between events concerning the demo script and those concerning the
+   demo-viewer. (They run in the same process.) Strange behaviour may be
+   the consequence and in the worst case you must close and restart the
+   viewer.
+   * * * * * * * *
+
+
+   (2) How to add your own demos to the demo repository
+
+   - place: same directory as turtledemo/__main__.py
+
+   - requirements on source code:
+       code must contain a main() function which will
+       be executed by the viewer (see provided example scripts)
+       main() may return a string which will be displayed
+       in the Label below the source code window (when execution
+       has finished.) 
+
+       !! For programs, which are EVENT DRIVEN, main must return
+       !! the string "EVENTLOOP". This informs the viewer, that the
+       !! script is still running and must be stopped by the user!
+
+

+    """
+    Create a new `Mock` object. `Mock` takes several optional arguments
+    that specify the behaviour of the Mock object:
+
+    * `spec`: This can be either a list of strings or an existing object (a
+      class or instance) that acts as the specification for the mock object. If
+      you pass in an object then a list of strings is formed by calling dir on
+      the object (excluding unsupported magic attributes and methods). Accessing
+      any attribute not in this list will raise an `AttributeError`.
+
+      If `spec` is an object (rather than a list of strings) then
+      `mock.__class__` returns the class of the spec object. This allows mocks
+      to pass `isinstance` tests.
+
+    * `spec_set`: A stricter variant of `spec`. If used, attempting to *set*
+      or get an attribute on the mock that isn't on the object passed as
+      `spec_set` will raise an `AttributeError`.
+
+    * `side_effect`: A function to be called whenever the Mock is called. See
+      the `side_effect` attribute. Useful for raising exceptions or
+      dynamically changing return values. The function is called with the same
+      arguments as the mock, and unless it returns `DEFAULT`, the return
+      value of this function is used as the return value.
+
+      If `side_effect` is an iterable then each call to the mock will return
+      the next value from the iterable. If any of the members of the iterable
+      are exceptions they will be raised instead of returned.
+
+    * `return_value`: The value returned when the mock is called. By default
+      this is a new Mock (created on first access). See the
+      `return_value` attribute.
+
+    * `wraps`: Item for the mock object to wrap. If `wraps` is not None then
+      calling the Mock will pass the call through to the wrapped object
+      (returning the real result). Attribute access on the mock will return a
+      Mock object that wraps the corresponding attribute of the wrapped object
+      (so attempting to access an attribute that doesn't exist will raise an
+      `AttributeError`).
+
+      If the mock has an explicit `return_value` set then calls are not passed
+      to the wrapped object and the `return_value` is returned instead.
+
+    * `name`: If the mock has a name then it will be used in the repr of the
+      mock. This can be useful for debugging. The name is propagated to child
+      mocks.
+
+    Mocks can also be called with arbitrary keyword arguments. These will be
+    used to set attributes on the mock after it is created.

+    `patch` acts as a function decorator, class decorator or a context
+    manager. Inside the body of the function or with statement, the `target`
+    is patched with a `new` object. When the function/with statement exits
+    the patch is undone.
+
+    If `new` is omitted, then the target is replaced with a
+    `MagicMock`. If `patch` is used as a decorator and `new` is
+    omitted, the created mock is passed in as an extra argument to the
+    decorated function. If `patch` is used as a context manager the created
+    mock is returned by the context manager.
+
+    `target` should be a string in the form `'package.module.ClassName'`. The
+    `target` is imported and the specified object replaced with the `new`
+    object, so the `target` must be importable from the environment you are
+    calling `patch` from. The target is imported when the decorated function
+    is executed, not at decoration time.
+
+    The `spec` and `spec_set` keyword arguments are passed to the `MagicMock`
+    if patch is creating one for you.
+
+    In addition you can pass `spec=True` or `spec_set=True`, which causes
+    patch to pass in the object being mocked as the spec/spec_set object.
+
+    `new_callable` allows you to specify a different class, or callable object,
+    that will be called to create the `new` object. By default `MagicMock` is
+    used.
+
+    A more powerful form of `spec` is `autospec`. If you set `autospec=True`
+    then the mock with be created with a spec from the object being replaced.
+    All attributes of the mock will also have the spec of the corresponding
+    attribute of the object being replaced. Methods and functions being
+    mocked will have their arguments checked and will raise a `TypeError` if
+    they are called with the wrong signature. For mocks replacing a class,
+    their return value (the 'instance') will have the same spec as the class.
+
+    Instead of `autospec=True` you can pass `autospec=some_object` to use an
+    arbitrary object as the spec instead of the one being replaced.
+
+    By default `patch` will fail to replace attributes that don't exist. If
+    you pass in `create=True`, and the attribute doesn't exist, patch will
+    create the attribute for you when the patched function is called, and
+    delete it again afterwards. This is useful for writing tests against
+    attributes that your production code creates at runtime. It is off by
+    default because it can be dangerous. With it switched on you can write
+    passing tests against APIs that don't actually exist!
+
+    Patch can be used as a `TestCase` class decorator. It works by
+    decorating each test method in the class. This reduces the boilerplate
+    code when your test methods share a common patchings set. `patch` finds
+    tests by looking for method names that start with `patch.TEST_PREFIX`.
+    By default this is `test`, which matches the way `unittest` finds tests.
+    You can specify an alternative prefix by setting `patch.TEST_PREFIX`.
+
+    Patch can be used as a context manager, with the with statement. Here the
+    patching applies to the indented block after the with statement. If you
+    use "as" then the patched object will be bound to the name after the
+    "as"; very useful if `patch` is creating a mock object for you.
+
+    `patch` takes arbitrary keyword arguments. These will be passed to
+    the `Mock` (or `new_callable`) on construction.
+
+    `patch.dict(...)`, `patch.multiple(...)` and `patch.object(...)` are
+    available for alternate use-cases.

+"""An extensible library for opening URLs using a variety of protocols
+
+The simplest way to use this module is to call the urlopen function,
+which accepts a string containing a URL or a Request object (described
+below).  It opens the URL and returns the results as file-like
+object; the returned object has some extra methods described below.
+
+The OpenerDirector manages a collection of Handler objects that do
+all the actual work.  Each Handler implements a particular protocol or
+option.  The OpenerDirector is a composite object that invokes the
+Handlers needed to open the requested URL.  For example, the
+HTTPHandler performs HTTP GET and POST requests and deals with
+non-error returns.  The HTTPRedirectHandler automatically deals with
+HTTP 301, 302, 303 and 307 redirect errors, and the HTTPDigestAuthHandler
+deals with digest authentication.
+
+urlopen(url, data=None) -- Basic usage is the same as original
+urllib.  pass the url and optionally data to post to an HTTP URL, and
+get a file-like object back.  One difference is that you can also pass
+a Request instance instead of URL.  Raises a URLError (subclass of
+OSError); for HTTP errors, raises an HTTPError, which can also be
+treated as a valid response.
+
+build_opener -- Function that creates a new OpenerDirector instance.
+Will install the default handlers.  Accepts one or more Handlers as
+arguments, either instances or Handler classes that it will
+instantiate.  If one of the argument is a subclass of the default
+handler, the argument will be installed instead of the default.
+
+install_opener -- Installs a new opener as the default opener.
+
+objects of interest:
+
+OpenerDirector -- Sets up the User Agent as the Python-urllib client and manages
+the Handler classes, while dealing with requests and responses.
+
+Request -- An object that encapsulates the state of a request.  The
+state can be as simple as the URL.  It can also include extra HTTP
+headers, e.g. a User-Agent.
+
+BaseHandler --
+
+internals:
+BaseHandler and parent
+_call_chain conventions
+
+Example usage:
+
+import urllib.request
+
+# set up authentication info
+authinfo = urllib.request.HTTPBasicAuthHandler()
+authinfo.add_password(realm='PDQ Application',
+                      uri='https://mahler:8092/site-updates.py',
+                      user='klem',
+                      passwd='geheim$parole')
+
+proxy_support = urllib.request.ProxyHandler({"http" : "http://ahad-haam:3128"})
+
+# build a new opener that adds authentication and caching FTP handlers
+opener = urllib.request.build_opener(proxy_support, authinfo,
+                                     urllib.request.CacheFTPHandler)
+
+# install it
+urllib.request.install_opener(opener)
+
+f = urllib.request.urlopen('http://www.python.org/')
+"""
+
+# XXX issues:
+# If an authentication error handler that tries to perform
+# authentication for some reason but fails, how should the error be
+# signalled?  The client needs to know the HTTP error code.  But if
+# the handler knows that the problem was, e.g., that it didn't know
+# that hash algo that requested in the challenge, it would be good to
+# pass that information along to the client, too.
+# ftp errors aren't handled cleanly
+# check digest against correct (i.e. non-apache) implementation
+
+# Possible extensions:
+# complex proxies  XXX not sure what exactly was meant by this
+# abstract factory for opener

+r"""UUID objects (universally unique identifiers) according to RFC 4122.
+
+This module provides immutable UUID objects (class UUID) and the functions
+uuid1(), uuid3(), uuid4(), uuid5() for generating version 1, 3, 4, and 5
+UUIDs as specified in RFC 4122.
+
+If all you want is a unique ID, you should probably call uuid1() or uuid4().
+Note that uuid1() may compromise privacy since it creates a UUID containing
+the computer's network address.  uuid4() creates a random UUID.
+
+Typical usage:
+
+    >>> import uuid
+
+    # make a UUID based on the host ID and current time
+    >>> uuid.uuid1()    # doctest: +SKIP
+    UUID('a8098c1a-f86e-11da-bd1a-00112444be1e')
+
+    # make a UUID using an MD5 hash of a namespace UUID and a name
+    >>> uuid.uuid3(uuid.NAMESPACE_DNS, 'python.org')
+    UUID('6fa459ea-ee8a-3ca4-894e-db77e160355e')
+
+    # make a random UUID
+    >>> uuid.uuid4()    # doctest: +SKIP
+    UUID('16fd2706-8baf-433b-82eb-8c7fada847da')
+
+    # make a UUID using a SHA-1 hash of a namespace UUID and a name
+    >>> uuid.uuid5(uuid.NAMESPACE_DNS, 'python.org')
+    UUID('886313e1-3b8a-5372-9b90-0c9aee199e5d')
+
+    # make a UUID from a string of hex digits (braces and hyphens ignored)
+    >>> x = uuid.UUID('{00010203-0405-0607-0809-0a0b0c0d0e0f}')
+
+    # convert a UUID to a string of hex digits in standard form
+    >>> str(x)
+    '00010203-0405-0607-0809-0a0b0c0d0e0f'
+
+    # get the raw 16 bytes of the UUID
+    >>> x.bytes
+    b'\x00\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f'

+    UUID objects are immutable, hashable, and usable as dictionary keys.
+    Converting a UUID to a string with str() yields something in the form
+    '12345678-1234-1234-1234-123456789abc'.  The UUID constructor accepts
+    five possible forms: a similar string of hexadecimal digits, or a tuple
+    of six integer fields (with 32-bit, 16-bit, 16-bit, 8-bit, 8-bit, and
+    48-bit values respectively) as an argument named 'fields', or a string
+    of 16 bytes (with all the integer fields in big-endian order) as an
+    argument named 'bytes', or a string of 16 bytes (with the first three
+    fields in little-endian order) as an argument named 'bytes_le', or a
+    single 128-bit integer as an argument named 'int'.
+
+    UUIDs have these read-only attributes:
+
+        bytes       the UUID as a 16-byte string (containing the six
+                    integer fields in big-endian byte order)
+

+                    and time_hi_version in little-endian byte order)
+
+        fields      a tuple of the six integer fields of the UUID,
+                    which are also available as six individual attributes
+                    and two derived attributes:
+
+            time_low                the first 32 bits of the UUID
+            time_mid                the next 16 bits of the UUID
+            time_hi_version         the next 16 bits of the UUID
+            clock_seq_hi_variant    the next 8 bits of the UUID
+            clock_seq_low           the next 8 bits of the UUID
+            node                    the last 48 bits of the UUID
+
+            time                    the 60-bit timestamp
+            clock_seq               the 14-bit sequence number
+
+        hex         the UUID as a 32-character hexadecimal string
+
+        int         the UUID as a 128-bit integer
+
+        urn         the UUID as a URN as specified in RFC 4122
+
+        variant     the UUID variant (one of the constants RESERVED_NCS,
+                    RFC_4122, RESERVED_MICROSOFT, or RESERVED_FUTURE)
+
+        version     the UUID version number (1 through 5, meaningful only

+"""Lightweight XML support for Python.
+
+ XML is an inherently hierarchical data format, and the most natural way to
+ represent it is with a tree.  This module has two classes for this purpose:
+
+    1. ElementTree represents the whole XML document as a tree and
+
+    2. Element represents a single node in this tree.
+
+ Interactions with the whole document (reading and writing to/from files) are
+ usually done on the ElementTree level.  Interactions with a single XML element
+ and its sub-elements are done on the Element level.
+
+ Element is a flexible container object designed to store hierarchical data
+ structures in memory. It can be described as a cross between a list and a
+ dictionary.  Each Element has a number of properties associated with it:
+
+    'tag' - a string containing the element's name.
+
+    'attributes' - a Python dictionary storing the element's attributes.
+
+    'text' - a string containing the element's text content.
+
+    'tail' - an optional string containing text after the element's end tag.
+
+    And a number of child elements stored in a Python sequence.
+
+ To create an element instance, use the Element constructor,
+ or the SubElement factory function.
+
+ You can also use the ElementTree class to wrap an element structure
+ and convert it to and from XML.

+# History:
+# 1999-01-14 fl  Created
+# 1999-01-15 fl  Changed dateTime to use localtime
+# 1999-01-16 fl  Added Binary/base64 element, default to RPC2 service
+# 1999-01-19 fl  Fixed array data element (from Skip Montanaro)
+# 1999-01-21 fl  Fixed dateTime constructor, etc.
+# 1999-02-02 fl  Added fault handling, handle empty sequences, etc.
+# 1999-02-10 fl  Fixed problem with empty responses (from Skip Montanaro)
+# 1999-06-20 fl  Speed improvements, pluggable parsers/transports (0.9.8)
+# 2000-11-28 fl  Changed boolean to check the truth value of its argument

+r"""XML-RPC Servers.
+
+This module can be used to create simple XML-RPC servers
+by creating a server and either installing functions, a
+class instance, or by extending the SimpleXMLRPCServer
+class.
+
+It can also be used to handle XML-RPC requests in a CGI
+environment using CGIXMLRPCRequestHandler.
+
+The Doc* classes can be used to create XML-RPC servers that
+serve pydoc-style documentation in response to HTTP
+GET requests. This documentation is dynamically generated
+based on the functions and methods registered with the
+server.
+
+A list of possible usage patterns follows:
+
+1. Install functions:
+
+server = SimpleXMLRPCServer(("localhost", 8000))
+server.register_function(pow)
+server.register_function(lambda x,y: x+y, 'add')
+server.serve_forever()
+
+2. Install an instance:
+
+class MyFuncs:
+    def __init__(self):
+        # make all of the sys functions available through sys.func_name
+        import sys
+        self.sys = sys
+    def _listMethods(self):
+        # implement this method so that system.listMethods
+        # knows to advertise the sys methods
+        return list_public_methods(self) + \
+                ['sys.' + method for method in list_public_methods(self.sys)]
+    def pow(self, x, y): return pow(x, y)
+    def add(self, x, y) : return x + y
+
+server = SimpleXMLRPCServer(("localhost", 8000))
+server.register_introspection_functions()
+server.register_instance(MyFuncs())
+server.serve_forever()
+
+3. Install an instance with custom dispatch method:
+
+class Math:
+    def _listMethods(self):
+        # this method must be present for system.listMethods
+        # to work
+        return ['add', 'pow']
+    def _methodHelp(self, method):
+        # this method must be present for system.methodHelp
+        # to work
+        if method == 'add':
+            return "add(2,3) => 5"
+        elif method == 'pow':
+            return "pow(x, y[, z]) => number"
+        else:
+            # By convention, return empty
+            # string if no help is available
+            return ""
+    def _dispatch(self, method, params):
+        if method == 'pow':
+            return pow(*params)
+        elif method == 'add':
+            return params[0] + params[1]
+        else:
+            raise ValueError('bad method')
+
+server = SimpleXMLRPCServer(("localhost", 8000))
+server.register_introspection_functions()
+server.register_instance(Math())
+server.serve_forever()
+
+4. Subclass SimpleXMLRPCServer:
+
+class MathServer(SimpleXMLRPCServer):
+    def _dispatch(self, method, params):
+        try:
+            # We are forcing the 'export_' prefix on methods that are
+            # callable through XML-RPC to prevent potential security
+            # problems
+            func = getattr(self, 'export_' + method)
+        except AttributeError:
+            raise Exception('method "%s" is not supported' % method)
+        else:
+            return func(*params)
+
+    def export_add(self, x, y):
+        return x + y
+
+server = MathServer(("localhost", 8000))
+server.serve_forever()
+
+5. CGI script:
+
+server = CGIXMLRPCRequestHandler()

-        ==========
-        
-        The Python SQL Toolkit and Object Relational Mapper
-        
-        Introduction
-        -------------
-        
-        SQLAlchemy is the Python SQL toolkit and Object Relational Mapper
-        that gives application developers the full power and
-        flexibility of SQL. SQLAlchemy provides a full suite
-        of well known enterprise-level persistence patterns,
-        designed for efficient and high-performing database
-        access, adapted into a simple and Pythonic domain
-        language.
-        
-        Major SQLAlchemy features include:
-        
-        * An industrial strength ORM, built 
-          from the core on the identity map, unit of work,
-          and data mapper patterns.   These patterns
-          allow transparent persistence of objects 
-          using a declarative configuration system.
-          Domain models
-          can be constructed and manipulated naturally,
-          and changes are synchronized with the
-          current transaction automatically.
-        * A relationally-oriented query system, exposing
-          the full range of SQL's capabilities 
-          explicitly, including joins, subqueries, 
-          correlation, and most everything else, 
-          in terms of the object model.
-          Writing queries with the ORM uses the same 
-          techniques of relational composition you use 
-          when writing SQL.  While you can drop into
-          literal SQL at any time, it's virtually never
-          needed.
-        * A comprehensive and flexible system 
-          of eager loading for related collections and objects.
-          Collections are cached within a session,
-          and can be loaded on individual access, all 
-          at once using joins, or by query per collection
-          across the full result set.
-        * A Core SQL construction system and DBAPI 
-          interaction layer.  The SQLAlchemy Core is
-          separate from the ORM and is a full database
-          abstraction layer in its own right, and includes
-          an extensible Python-based SQL expression 
-          language, schema metadata, connection pooling, 
-          type coercion, and custom types.
-        * All primary and foreign key constraints are 
-          assumed to be composite and natural.  Surrogate
-          integer primary keys are of course still the 
-          norm, but SQLAlchemy never assumes or hardcodes
-          to this model.
-        * Database introspection and generation.  Database
-          schemas can be "reflected" in one step into
-          Python structures representing database metadata;
-          those same structures can then generate 
-          CREATE statements right back out - all within
-          the Core, independent of the ORM.
-        
-        SQLAlchemy's philosophy:
-        
-        * SQL databases behave less and less like object
-          collections the more size and performance start to
-          matter; object collections behave less and less like
-          tables and rows the more abstraction starts to matter.
-          SQLAlchemy aims to accommodate both of these
-          principles.
-        * An ORM doesn't need to hide the "R".   A relational
-          database provides rich, set-based functionality
-          that should be fully exposed.   SQLAlchemy's
-          ORM provides an open-ended set of patterns
-          that allow a developer to construct a custom
-          mediation layer between a domain model and 
-          a relational schema, turning the so-called
-          "object relational impedance" issue into
-          a distant memory.
-        * The developer, in all cases, makes all decisions
-          regarding the design, structure, and naming conventions
-          of both the object model as well as the relational
-          schema.   SQLAlchemy only provides the means
-          to automate the execution of these decisions.
-        * With SQLAlchemy, there's no such thing as 
-          "the ORM generated a bad query" - you 
-          retain full control over the structure of 
-          queries, including how joins are organized,
-          how subqueries and correlation is used, what 
-          columns are requested.  Everything SQLAlchemy
-          does is ultimately the result of a developer-
-          initiated decision.
-        * Don't use an ORM if the problem doesn't need one.
-          SQLAlchemy consists of a Core and separate ORM
-          component.   The Core offers a full SQL expression
-          language that allows Pythonic construction 
-          of SQL constructs that render directly to SQL
-          strings for a target database, returning
-          result sets that are essentially enhanced DBAPI
-          cursors.
-        * Transactions should be the norm.  With SQLAlchemy's
-          ORM, nothing goes to permanent storage until
-          commit() is called.  SQLAlchemy encourages applications
-          to create a consistent means of delineating
-          the start and end of a series of operations.
-        * Never render a literal value in a SQL statement.
-          Bound parameters are used to the greatest degree
-          possible, allowing query optimizers to cache 
-          query plans effectively and making SQL injection
-          attacks a non-issue.

-        
-        ``cryptography`` is a package which provides cryptographic recipes and
-        primitives to Python developers.  Our goal is for it to be your "cryptographic
-        standard library". It supports Python 2.6-2.7, Python 3.2+, and PyPy.
-        
-        ``cryptography`` includes both high level recipes, and low level interfaces to
-        common cryptographic algorithms such as symmetric ciphers, message digests and
-        key derivation functions. For example, to encrypt something with
-        ``cryptography``'s high level symmetric encryption recipe:
-        
-        .. code-block:: pycon
-        
-            >>> from cryptography.fernet import Fernet
-            >>> # Put this somewhere safe!
-            >>> key = Fernet.generate_key()
-            >>> f = Fernet(key)
-            >>> token = f.encrypt(b"A really secret message. Not for prying eyes.")
-            >>> token
-            '...'
-            >>> f.decrypt(token)
-            'A really secret message. Not for prying eyes.'
-        
-        You can find more information in the `documentation`_.
-        
-        Discussion
-        ~~~~~~~~~~
-        
-        If you run into bugs, you can file them in our `issue tracker`_.
-        
-        We maintain a `cryptography-dev`_ mailing list for development discussion.
-        
-        You can also join ``#cryptography-dev`` on Freenode to ask questions or get
-        involved.

-Version: 1.2
-Summary: Ed25519 public-key signatures
-Home-page: https://github.com/warner/python-ed25519
-Author: Brian Warner
-Author-email: warner-python-ed25519@lothar.com
-License: MIT
-Description: Python bindings to the Ed25519 public-key signature system.
-        
-        This offers a comfortable python interface to a C implementation of the
-        Ed25519 public-key signature system (http://ed25519.cr.yp.to/), using the
-        portable 'ref' code from the 'SUPERCOP' benchmarking suite.
-        
-        This system provides high (128-bit) security, short (32-byte) keys, short
-        (64-byte) signatures, and fast (2-6ms) operation. Please see the README for
-        more details.

-Metadata-Version: 1.1
-Name: six
-Version: 1.7.3
-Summary: Python 2 and 3 compatibility utilities
-Home-page: http://pypi.python.org/pypi/six/
-Author: Benjamin Peterson
-Author-email: benjamin@python.org
-License: MIT
-Description: Six is a Python 2 and 3 compatibility library.  It provides utility functions
-        for smoothing over the differences between the Python versions with the goal of
-        writing Python code that is compatible on both Python versions.  See the
-        documentation for more information on what is provided.
-        
-        Six supports every Python version since 2.5.  It is contained in only one Python
-        file, so it can be easily copied into your project. (The copyright and license
-        notice must be retained.)
-        
-        Online documentation is at http://pythonhosted.org/six/.
-        
-        Bugs can be reported to http://bitbucket.org/gutworth/six.  The code can also be
-        found there.
-        
-        For questions about six or porting in general, email the python-porting mailing
-        list: http://mail.python.org/mailman/listinfo/python-porting

-    :name: Firebird
-
-Firebird Dialects
------------------
-
-Firebird offers two distinct dialects_ (not to be confused with a
-SQLAlchemy ``Dialect``):
-
-dialect 1
-  This is the old syntax and behaviour, inherited from Interbase pre-6.0.
-
-dialect 3
-  This is the newer and supported syntax, introduced in Interbase 6.0.
-
-The SQLAlchemy Firebird dialect detects these versions and
-adjusts its representation of SQL accordingly.  However,
-support for dialect 1 is not well tested and probably has
-incompatibilities.
-
-Locking Behavior
-----------------
-
-Firebird locks tables aggressively.  For this reason, a DROP TABLE may
-hang until other transactions are released.  SQLAlchemy does its best
-to release transactions as quickly as possible.  The most common cause
-of hanging transactions is a non-fully consumed result set, i.e.::
-
-    result = engine.execute("select * from table")
-    row = result.fetchone()
-    return
-
-Where above, the ``ResultProxy`` has not been fully consumed.  The
-connection will be returned to the pool and the transactional state
-rolled back once the Python garbage collector reclaims the objects
-which hold onto the connection, which often occurs asynchronously.
-The above use case can be alleviated by calling ``first()`` on the
-``ResultProxy`` which will fetch the first row and immediately close
-all remaining cursor/connection resources.
-
-RETURNING support
------------------
-
-Firebird 2.0 supports returning a result set from inserts, and 2.1
-extends that to deletes and updates. This is generically exposed by
-the SQLAlchemy ``returning()`` method, such as::
-
-    # INSERT..RETURNING
-    result = table.insert().returning(table.c.col1, table.c.col2).\\
-                   values(name='foo')
-    print result.fetchall()
-
-    # UPDATE..RETURNING
-    raises = empl.update().returning(empl.c.id, empl.c.salary).\\
-                  where(empl.c.sales>100).\\
-                  values(dict(salary=empl.c.salary * 1.1))
-    print raises.fetchall()

-.. dialect:: firebird+fdb
-    :name: fdb
-    :dbapi: pyodbc
-    :connectstring: firebird+fdb://user:password@host:port/path/to/db[?key=value&key=value...]
-    :url: http://pypi.python.org/pypi/fdb/
-
-    fdb is a kinterbasdb compatible DBAPI for Firebird.
-
-    .. versionadded:: 0.8 - Support for the fdb Firebird driver.
-
-    .. versionchanged:: 0.9 - The fdb dialect is now the default dialect
-       under the ``firebird://`` URL space, as ``fdb`` is now the official
-       Python driver for Firebird.
-
-Arguments
-----------
-
-The ``fdb`` dialect is based on the :mod:`sqlalchemy.dialects.firebird.kinterbasdb`
-dialect, however does not accept every argument that Kinterbasdb does.
-
-* ``enable_rowcount`` - True by default, setting this to False disables
-  the usage of "cursor.rowcount" with the
-  Kinterbasdb dialect, which SQLAlchemy ordinarily calls upon automatically
-  after any UPDATE or DELETE statement.   When disabled, SQLAlchemy's
-  ResultProxy will return -1 for result.rowcount.   The rationale here is
-  that Kinterbasdb requires a second round trip to the database when
-  .rowcount is called -  since SQLA's resultproxy automatically closes
-  the cursor after a non-result-returning statement, rowcount must be
-  called, if at all, before the result object is returned.   Additionally,
-  cursor.rowcount may not return correct results with older versions
-  of Firebird, and setting this flag to False will also cause the
-  SQLAlchemy ORM to ignore its usage. The behavior can also be controlled on a
-  per-execution basis using the ``enable_rowcount`` option with
-  :meth:`.Connection.execution_options`::
-
-      conn = engine.connect().execution_options(enable_rowcount=True)
-      r = conn.execute(stmt)
-      print r.rowcount
-
-* ``retaining`` - False by default.   Setting this to True will pass the
-  ``retaining=True`` keyword argument to the ``.commit()`` and ``.rollback()``
-  methods of the DBAPI connection, which can improve performance in some
-  situations, but apparently with significant caveats.
-  Please read the fdb and/or kinterbasdb DBAPI documentation in order to
-  understand the implications of this flag.
-
-  .. versionadded:: 0.8.2 - ``retaining`` keyword argument specifying
-     transaction retaining behavior - in 0.8 it defaults to ``True``
-     for backwards compatibility.
-
-  .. versionchanged:: 0.9.0 - the ``retaining`` flag defaults to ``False``.
-     In 0.8 it defaulted to ``True``.
-
-  .. seealso::
-
-    http://pythonhosted.org/fdb/usage-guide.html#retaining-transactions - information
-    on the "retaining" flag.

-
-
-Auto Increment Behavior
------------------------
-
-``IDENTITY`` columns are supported by using SQLAlchemy
-``schema.Sequence()`` objects. In other words::
-
-    from sqlalchemy import Table, Integer, Sequence, Column
-
-    Table('test', metadata,
-           Column('id', Integer,
-                  Sequence('blah',100,10), primary_key=True),
-           Column('name', String(20))
-         ).create(some_engine)
-
-would yield::
-
-   CREATE TABLE test (
-     id INTEGER NOT NULL IDENTITY(100,10) PRIMARY KEY,
-     name VARCHAR(20) NULL,
-     )
-
-Note that the ``start`` and ``increment`` values for sequences are
-optional and will default to 1,1.
-
-Implicit ``autoincrement`` behavior works the same in MSSQL as it
-does in other dialects and results in an ``IDENTITY`` column.
-
-* Support for ``SET IDENTITY_INSERT ON`` mode (automagic on / off for
-  ``INSERT`` s)
-
-* Support for auto-fetching of ``@@IDENTITY/@@SCOPE_IDENTITY()`` on
-  ``INSERT``
-
-Collation Support
------------------
-
-Character collations are supported by the base string types,
-specified by the string argument "collation"::
-
-    from sqlalchemy import VARCHAR
-    Column('login', VARCHAR(32, collation='Latin1_General_CI_AS'))
-
-When such a column is associated with a :class:`.Table`, the
-CREATE TABLE statement for this column will yield::
-
-    login VARCHAR(32) COLLATE Latin1_General_CI_AS NULL
-
-.. versionadded:: 0.8 Character collations are now part of the base string
-   types.
-
-LIMIT/OFFSET Support
---------------------
-
-MSSQL has no support for the LIMIT or OFFSET keysowrds. LIMIT is
-supported directly through the ``TOP`` Transact SQL keyword::
-
-    select.limit
-
-will yield::
-
-    SELECT TOP n
-
-If using SQL Server 2005 or above, LIMIT with OFFSET
-support is available through the ``ROW_NUMBER OVER`` construct.
-For versions below 2005, LIMIT with OFFSET usage will fail.
-
-Nullability
------------
-MSSQL has support for three levels of column nullability. The default
-nullability allows nulls and is explicit in the CREATE TABLE
-construct::
-
-    name VARCHAR(20) NULL
-
-If ``nullable=None`` is specified then no specification is made. In
-other words the database's configured default is used. This will
-render::
-
-    name VARCHAR(20)
-
-If ``nullable`` is ``True`` or ``False`` then the column will be
-``NULL` or ``NOT NULL`` respectively.
-
-Date / Time Handling
---------------------
-DATE and TIME are supported.   Bind parameters are converted
-to datetime.datetime() objects as required by most MSSQL drivers,
-and results are processed from strings if needed.
-The DATE and TIME types are not available for MSSQL 2005 and
-previous - if a server version below 2008 is detected, DDL
-for these types will be issued as DATETIME.
-
-.. _mssql_indexes:
-
-Clustered Index Support
------------------------
-
-The MSSQL dialect supports clustered indexes (and primary keys) via the
-``mssql_clustered`` option.  This option is available to :class:`.Index`,
-:class:`.UniqueConstraint`. and :class:`.PrimaryKeyConstraint`.
-
-To generate a clustered index::
-
-    Index("my_index", table.c.x, mssql_clustered=True)
-
-which renders the index as ``CREATE CLUSTERED INDEX my_index ON table (x)``.
-
-.. versionadded:: 0.8
-
-To generate a clustered primary key use::
-
-    Table('my_table', metadata,
-          Column('x', ...),
-          Column('y', ...),
-          PrimaryKeyConstraint("x", "y", mssql_clustered=True))
-
-which will render the table, for example, as::
-
-  CREATE TABLE my_table (x INTEGER NOT NULL, y INTEGER NOT NULL, PRIMARY KEY CLUSTERED (x, y))
-
-Similarly, we can generate a clustered unique constraint using::
-
-    Table('my_table', metadata,
-          Column('x', ...),
-          Column('y', ...),
-          PrimaryKeyConstraint("x"),
-          UniqueConstraint("y", mssql_clustered=True),
-          )
-
-  .. versionadded:: 0.9.2
-
-MSSQL-Specific Index Options
------------------------------
-
-In addition to clustering, the MSSQL dialect supports other special options
-for :class:`.Index`.
-
-INCLUDE
-^^^^^^^
-
-The ``mssql_include`` option renders INCLUDE(colname) for the given string names::
-
-    Index("my_index", table.c.x, mssql_include=['y'])
-
-would render the index as ``CREATE INDEX my_index ON table (x) INCLUDE (y)``
-
-.. versionadded:: 0.8
-
-Index ordering
-^^^^^^^^^^^^^^
-
-Index ordering is available via functional expressions, such as::
-
-    Index("my_index", table.c.x.desc())
-
-would render the index as ``CREATE INDEX my_index ON table (x DESC)``
-
-.. versionadded:: 0.8
-
-.. seealso::
-
-    :ref:`schema_indexes_functional`
-
-Compatibility Levels
---------------------
-MSSQL supports the notion of setting compatibility levels at the
-database level. This allows, for instance, to run a database that
-is compatible with SQL2000 while running on a SQL2005 database
-server. ``server_version_info`` will always return the database
-server version information (in this case SQL2005) and not the
-compatibility level information. Because of this, if running under
-a backwards compatibility mode SQAlchemy may attempt to use T-SQL
-statements that are unable to be parsed by the database server.
-
-Triggers
---------
-
-SQLAlchemy by default uses OUTPUT INSERTED to get at newly
-generated primary key values via IDENTITY columns or other
-server side defaults.   MS-SQL does not
-allow the usage of OUTPUT INSERTED on tables that have triggers.
-To disable the usage of OUTPUT INSERTED on a per-table basis,
-specify ``implicit_returning=False`` for each :class:`.Table`
-which has triggers::
-
-    Table('mytable', metadata,
-        Column('id', Integer, primary_key=True),
-        # ...,
-        implicit_returning=False
-    )
-
-Declarative form::
-
-    class MyClass(Base):
-        # ...
-        __table_args__ = {'implicit_returning':False}
-
-
-This option can also be specified engine-wide using the
-``implicit_returning=False`` argument on :func:`.create_engine`.
-
-Enabling Snapshot Isolation
----------------------------
-
-Not necessarily specific to SQLAlchemy, SQL Server has a default transaction
-isolation mode that locks entire tables, and causes even mildly concurrent
-applications to have long held locks and frequent deadlocks.
-Enabling snapshot isolation for the database as a whole is recommended
-for modern levels of concurrency support.  This is accomplished via the
-following ALTER DATABASE commands executed at the SQL prompt::
-
-    ALTER DATABASE MyDatabase SET ALLOW_SNAPSHOT_ISOLATION ON
-
-    ALTER DATABASE MyDatabase SET READ_COMMITTED_SNAPSHOT ON
-
-Background on SQL Server snapshot isolation is available at
-http://msdn.microsoft.com/en-us/library/ms175095.aspx.
-
-Known Issues
-------------
-
-* No support for more than one ``IDENTITY`` column per table
-* reflection of indexes does not work with versions older than
-  SQL Server 2005

-
-Execution Modes
----------------
-
-mxODBC features two styles of statement execution, using the
-``cursor.execute()`` and ``cursor.executedirect()`` methods (the second being
-an extension to the DBAPI specification). The former makes use of a particular
-API call specific to the SQL Server Native Client ODBC driver known
-SQLDescribeParam, while the latter does not.
-
-mxODBC apparently only makes repeated use of a single prepared statement
-when SQLDescribeParam is used. The advantage to prepared statement reuse is
-one of performance. The disadvantage is that SQLDescribeParam has a limited
-set of scenarios in which bind parameters are understood, including that they
-cannot be placed within the argument lists of function calls, anywhere outside
-the FROM, or even within subqueries within the FROM clause - making the usage
-of bind parameters within SELECT statements impossible for all but the most
-simplistic statements.
-
-For this reason, the mxODBC dialect uses the "native" mode by default only for
-INSERT, UPDATE, and DELETE statements, and uses the escaped string mode for
-all other statements.
-
-This behavior can be controlled via
-:meth:`~sqlalchemy.sql.expression.Executable.execution_options` using the
-``native_odbc_execute`` flag with a value of ``True`` or ``False``, where a
-value of ``True`` will unconditionally use native bind parameters and a value
-of ``False`` will unconditionally use string-escaped parameters.

-    DRIVER={SQL Server};Server=host,123;Database=db;UID=user;PWD=pass
-
-* ``mssql+pyodbc://user:pass@host/db?port=123`` - connects using a connection
-  string that includes the port
-  information as a separate ``port`` keyword. This will create the
-  following connection string::
-
-    DRIVER={SQL Server};Server=host;Database=db;UID=user;PWD=pass;port=123
-
-* ``mssql+pyodbc://user:pass@host/db?driver=MyDriver`` - connects using a connection
-  string that includes a custom
-  ODBC driver name.  This will create the following connection string::
-
-    DRIVER={MyDriver};Server=host;Database=db;UID=user;PWD=pass
-
-If you require a connection string that is outside the options
-presented above, use the ``odbc_connect`` keyword to pass in a
-urlencoded connection string. What gets passed in will be urldecoded
-and passed directly.
-
-For example::
-
-    mssql+pyodbc:///?odbc_connect=dsn%3Dmydsn%3BDatabase%3Ddb
-
-would create the following connection string::
-
-    dsn=mydsn;Database=db
-
-Encoding your connection string can be easily accomplished through
-the python shell. For example::
-
-    >>> import urllib
-    >>> urllib.quote_plus('dsn=mydsn;Database=db')
-    'dsn%3Dmydsn%3BDatabase%3Ddb'

-Unicode Binds
--------------
-
-The current state of PyODBC on a unix backend with FreeTDS and/or
-EasySoft is poor regarding unicode; different OS platforms and versions of UnixODBC
-versus IODBC versus FreeTDS/EasySoft versus PyODBC itself dramatically
-alter how strings are received.  The PyODBC dialect attempts to use all the information
-it knows to determine whether or not a Python unicode literal can be
-passed directly to the PyODBC driver or not; while SQLAlchemy can encode
-these to bytestrings first, some users have reported that PyODBC mis-handles
-bytestrings for certain encodings and requires a Python unicode object,
-while the author has observed widespread cases where a Python unicode
-is completely misinterpreted by PyODBC, particularly when dealing with
-the information schema tables used in table reflection, and the value
-must first be encoded to a bytestring.
-
-It is for this reason that whether or not unicode literals for bound
-parameters be sent to PyODBC can be controlled using the
-``supports_unicode_binds`` parameter to ``create_engine()``.  When
-left at its default of ``None``, the PyODBC dialect will use its
-best guess as to whether or not the driver deals with unicode literals
-well.  When ``False``, unicode literals will be encoded first, and when
-``True`` unicode literals will be passed straight through.  This is an interim
-flag that hopefully should not be needed when the unicode situation stabilizes
-for unix + PyODBC.

-.. dialect:: mysql
-    :name: MySQL
-
-Supported Versions and Features
--------------------------------
-
-SQLAlchemy supports MySQL starting with version 4.1 through modern releases.
-However, no heroic measures are taken to work around major missing
-SQL features - if your server version does not support sub-selects, for
-example, they won't work in SQLAlchemy either.
-
-See the official MySQL documentation for detailed information about features
-supported in any given server release.
-
-.. _mysql_connection_timeouts:
-
-Connection Timeouts
--------------------
-
-MySQL features an automatic connection close behavior, for connections that have
-been idle for eight hours or more.   To circumvent having this issue, use the
-``pool_recycle`` option which controls the maximum age of any connection::
-
-    engine = create_engine('mysql+mysqldb://...', pool_recycle=3600)
-
-.. _mysql_storage_engines:
-
-CREATE TABLE arguments including Storage Engines
-------------------------------------------------
-
-MySQL's CREATE TABLE syntax includes a wide array of special options,
-including ``ENGINE``, ``CHARSET``, ``MAX_ROWS``, ``ROW_FORMAT``, ``INSERT_METHOD``, and many more.
-To accommodate the rendering of these arguments, specify the form
-``mysql_argument_name="value"``.  For example, to specify a table with
-``ENGINE`` of ``InnoDB``, ``CHARSET`` of ``utf8``, and ``KEY_BLOCK_SIZE`` of ``1024``::
-
-  Table('mytable', metadata,
-        Column('data', String(32)),
-        mysql_engine='InnoDB',
-        mysql_charset='utf8',
-        mysql_key_block_size="1024"
-       )
-
-The MySQL dialect will normally transfer any keyword specified as ``mysql_keyword_name``
-to be rendered as ``KEYWORD_NAME`` in the ``CREATE TABLE`` statement.  A handful
-of these names will render with a space instead of an underscore; to support this,
-the MySQL dialect has awareness of these particular names, which include
-``DATA DIRECTORY`` (e.g. ``mysql_data_directory``), ``CHARACTER SET`` (e.g.
-``mysql_character_set``) and ``INDEX DIRECTORY`` (e.g. ``mysql_index_directory``).
-
-The most common argument is ``mysql_engine``, which refers to the storage engine
-for the table.  Historically, MySQL server installations would default
-to ``MyISAM`` for this value, although newer versions may be defaulting
-to ``InnoDB``.  The ``InnoDB`` engine is typically preferred for its support
-of transactions and foreign keys.
-
-A :class:`.Table` that is created in a MySQL database with a storage engine
-of ``MyISAM`` will be essentially non-transactional, meaning any INSERT/UPDATE/DELETE
-statement referring to this table will be invoked as autocommit.   It also will have no
-support for foreign key constraints; while the ``CREATE TABLE`` statement
-accepts foreign key options, when using the ``MyISAM`` storage engine these
-arguments are discarded.  Reflecting such a table will also produce no
-foreign key constraint information.
-
-For fully atomic transactions as well as support for foreign key
-constraints, all participating ``CREATE TABLE`` statements must specify a
-transactional engine, which in the vast majority of cases is ``InnoDB``.
-
-.. seealso::
-
-    `The InnoDB Storage Engine
-    <http://dev.mysql.com/doc/refman/5.0/en/innodb-storage-engine.html>`_ -
-    on the MySQL website.
-
-Case Sensitivity and Table Reflection
--------------------------------------
-
-MySQL has inconsistent support for case-sensitive identifier
-names, basing support on specific details of the underlying
-operating system. However, it has been observed that no matter
-what case sensitivity behavior is present, the names of tables in
-foreign key declarations are *always* received from the database
-as all-lower case, making it impossible to accurately reflect a
-schema where inter-related tables use mixed-case identifier names.
-
-Therefore it is strongly advised that table names be declared as
-all lower case both within SQLAlchemy as well as on the MySQL
-database itself, especially if database reflection features are
-to be used.
-
-Transaction Isolation Level
----------------------------
-
-:func:`.create_engine` accepts an ``isolation_level``
-parameter which results in the command ``SET SESSION
-TRANSACTION ISOLATION LEVEL <level>`` being invoked for
-every new connection. Valid values for this parameter are
-``READ COMMITTED``, ``READ UNCOMMITTED``,
-``REPEATABLE READ``, and ``SERIALIZABLE``::
-
-    engine = create_engine(
-                    "mysql://scott:tiger@localhost/test",
-                    isolation_level="READ UNCOMMITTED"
-                )
-
-.. versionadded:: 0.7.6
-
-AUTO_INCREMENT Behavior
------------------------
-
-When creating tables, SQLAlchemy will automatically set ``AUTO_INCREMENT`` on
-the first :class:`.Integer` primary key column which is not marked as a foreign key::
-
-  >>> t = Table('mytable', metadata,
-  ...   Column('mytable_id', Integer, primary_key=True)
-  ... )
-  >>> t.create()
-  CREATE TABLE mytable (
-          id INTEGER NOT NULL AUTO_INCREMENT,
-          PRIMARY KEY (id)
-  )
-
-You can disable this behavior by passing ``False`` to the :paramref:`~.Column.autoincrement`
-argument of :class:`.Column`.  This flag can also be used to enable
-auto-increment on a secondary column in a multi-column key for some storage
-engines::
-
-  Table('mytable', metadata,
-        Column('gid', Integer, primary_key=True, autoincrement=False),
-        Column('id', Integer, primary_key=True)
-       )
-
-Ansi Quoting Style
-------------------
-
-MySQL features two varieties of identifier "quoting style", one using
-backticks and the other using quotes, e.g. ```some_identifier```  vs.
-``"some_identifier"``.   All MySQL dialects detect which version
-is in use by checking the value of ``sql_mode`` when a connection is first
-established with a particular :class:`.Engine`.  This quoting style comes
-into play when rendering table and column names as well as when reflecting
-existing database structures.  The detection is entirely automatic and
-no special configuration is needed to use either quoting style.
-
-.. versionchanged:: 0.6 detection of ANSI quoting style is entirely automatic,
-   there's no longer any end-user ``create_engine()`` options in this regard.
-
-MySQL SQL Extensions
---------------------
-
-Many of the MySQL SQL extensions are handled through SQLAlchemy's generic
-function and operator support::
-
-  table.select(table.c.password==func.md5('plaintext'))
-  table.select(table.c.username.op('regexp')('^[a-d]'))
-
-And of course any valid MySQL statement can be executed as a string as well.
-
-Some limited direct support for MySQL extensions to SQL is currently
-available.
-
-* SELECT pragma::
-
-    select(..., prefixes=['HIGH_PRIORITY', 'SQL_SMALL_RESULT'])
-
-* UPDATE with LIMIT::
-
-    update(..., mysql_limit=10)
-
-rowcount Support
-----------------
-
-SQLAlchemy standardizes the DBAPI ``cursor.rowcount`` attribute to be the
-usual definition of "number of rows matched by an UPDATE or DELETE" statement.
-This is in contradiction to the default setting on most MySQL DBAPI drivers,
-which is "number of rows actually modified/deleted".  For this reason, the
-SQLAlchemy MySQL dialects always set the ``constants.CLIENT.FOUND_ROWS`` flag,
-or whatever is equivalent for the DBAPI in use, on connect, unless the flag value
-is overridden using DBAPI-specific options
-(such as ``client_flag`` for the MySQL-Python driver, ``found_rows`` for the
-OurSQL driver).
-
-See also:
-
-:attr:`.ResultProxy.rowcount`
-
-
-CAST Support
-------------
-
-MySQL documents the CAST operator as available in version 4.0.2.  When using the
-SQLAlchemy :func:`.cast` function, SQLAlchemy
-will not render the CAST token on MySQL before this version, based on server version
-detection, instead rendering the internal expression directly.
-
-CAST may still not be desirable on an early MySQL version post-4.0.2, as it didn't
-add all datatype support until 4.1.1.   If your application falls into this
-narrow area, the behavior of CAST can be controlled using the
-:ref:`sqlalchemy.ext.compiler_toplevel` system, as per the recipe below::

-
-.. _mysql_indexes:
-
-MySQL Specific Index Options
-----------------------------
-
-MySQL-specific extensions to the :class:`.Index` construct are available.
-
-Index Length
-~~~~~~~~~~~~~
-
-MySQL provides an option to create index entries with a certain length, where
-"length" refers to the number of characters or bytes in each value which will
-become part of the index. SQLAlchemy provides this feature via the
-``mysql_length`` parameter::
-
-    Index('my_index', my_table.c.data, mysql_length=10)
-
-    Index('a_b_idx', my_table.c.a, my_table.c.b, mysql_length={'a': 4, 'b': 9})
-
-Prefix lengths are given in characters for nonbinary string types and in bytes
-for binary string types. The value passed to the keyword argument *must* be
-either an integer (and, thus, specify the same prefix length value for all
-columns of the index) or a dict in which keys are column names and values are
-prefix length values for corresponding columns. MySQL only allows a length for
-a column of an index if it is for a CHAR, VARCHAR, TEXT, BINARY, VARBINARY and
-BLOB.
-
-.. versionadded:: 0.8.2 ``mysql_length`` may now be specified as a dictionary
-   for use with composite indexes.
-
-Index Types
-~~~~~~~~~~~~~
-
-Some MySQL storage engines permit you to specify an index type when creating
-an index or primary key constraint. SQLAlchemy provides this feature via the
-``mysql_using`` parameter on :class:`.Index`::
-
-    Index('my_index', my_table.c.data, mysql_using='hash')
-
-As well as the ``mysql_using`` parameter on :class:`.PrimaryKeyConstraint`::
-
-    PrimaryKeyConstraint("data", mysql_using='hash')
-
-The value passed to the keyword argument will be simply passed through to the
-underlying CREATE INDEX or PRIMARY KEY clause, so it *must* be a valid index
-type for your MySQL storage engine.
-
-More information can be found at:
-
-http://dev.mysql.com/doc/refman/5.0/en/create-index.html

-
-.. _mysql_foreign_keys:
-
-MySQL Foreign Keys
-------------------
-
-MySQL's behavior regarding foreign keys has some important caveats.
-
-Foreign Key Arguments to Avoid
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-MySQL does not support the foreign key arguments "DEFERRABLE", "INITIALLY",
-or "MATCH".  Using the ``deferrable`` or ``initially`` keyword argument with
-:class:`.ForeignKeyConstraint` or :class:`.ForeignKey` will have the effect of these keywords being
-rendered in a DDL expression, which will then raise an error on MySQL.
-In order to use these keywords on a foreign key while having them ignored
-on a MySQL backend, use a custom compile rule::
-
-    from sqlalchemy.ext.compiler import compiles
-    from sqlalchemy.schema import ForeignKeyConstraint
-
-    @compiles(ForeignKeyConstraint, "mysql")
-    def process(element, compiler, **kw):
-        element.deferrable = element.initially = None
-        return compiler.visit_foreign_key_constraint(element, **kw)
-
-.. versionchanged:: 0.9.0 - the MySQL backend no longer silently ignores
-   the ``deferrable`` or ``initially`` keyword arguments of :class:`.ForeignKeyConstraint`
-   and :class:`.ForeignKey`.
-
-The "MATCH" keyword is in fact more insidious, and is explicitly disallowed
-by SQLAlchemy in conjunction with the MySQL backend.  This argument is silently
-ignored by MySQL, but in addition has the effect of ON UPDATE and ON DELETE options
-also being ignored by the backend.   Therefore MATCH should never be used with the
-MySQL backend; as is the case with DEFERRABLE and INITIALLY, custom compilation
-rules can be used to correct a MySQL ForeignKeyConstraint at DDL definition time.
-
-.. versionadded:: 0.9.0 - the MySQL backend will raise a :class:`.CompileError`
-   when the ``match`` keyword is used with :class:`.ForeignKeyConstraint`
-   or :class:`.ForeignKey`.
-
-Reflection of Foreign Key Constraints
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Not all MySQL storage engines support foreign keys.  When using the
-very common ``MyISAM`` MySQL storage engine, the information loaded by table
-reflection will not include foreign keys.  For these tables, you may supply a
-:class:`~sqlalchemy.ForeignKeyConstraint` at reflection time::
-
-  Table('mytable', metadata,
-        ForeignKeyConstraint(['other_id'], ['othertable.other_id']),
-        autoload=True
-       )
-
-.. seealso::

-          value.  Takes precedence to 'ascii' or 'unicode' short-hand.
-
-        :param collation: Optional, a column-level collation for this string
-          value.  Takes precedence to 'binary' short-hand.
-
-        :param ascii: Defaults to False: short-hand for the ``latin1``
-          character set, generates ASCII in schema.
-
-        :param unicode: Defaults to False: short-hand for the ``ucs2``
-          character set, generates UNICODE in schema.
-
-        :param binary: Defaults to False: short-hand, pick the binary
-          collation type that matches the column's character set.  Generates
-          BINARY in schema.  This does not affect the type of data stored,
-          only the collation of character data.
-
-        :param quoting: Defaults to 'auto': automatically determine enum value
-          quoting.  If all enum values are surrounded by the same quoting
-          character, then use 'quoted' mode.  Otherwise, use 'unquoted' mode.

-
-Unicode
--------
-
-MySQLdb requires a "charset" parameter to be passed in order for it
-to handle non-ASCII characters correctly.   When this parameter is passed,
-MySQLdb will also implicitly set the "use_unicode" flag to true, which means
-that it will return Python unicode objects instead of bytestrings.
-However, SQLAlchemy's decode process, when C extensions are enabled,
-is orders of magnitude faster than that of MySQLdb as it does not call into
-Python functions to do so.  Therefore, the **recommended URL to use for
-unicode** will include both charset and use_unicode=0::
-
-    create_engine("mysql+mysqldb://user:pass@host/dbname?charset=utf8&use_unicode=0")
-
-As of this writing, MySQLdb only runs on Python 2.   It is not known how
-MySQLdb behaves on Python 3 as far as unicode decoding.
-
-
-Known Issues
--------------
-
-MySQL-python version 1.2.2 has a serious memory leak related
-to unicode conversion, a feature which is disabled via ``use_unicode=0``.
-It is strongly advised to use the latest version of MySQL-Python.

-Unicode
--------
-
-oursql defaults to using ``utf8`` as the connection charset, but other
-encodings may be used instead. Like the MySQL-Python driver, unicode support
-can be completely disabled::
-
-  # oursql sets the connection charset to utf8 automatically; all strings come
-  # back as utf8 str
-  create_engine('mysql+oursql:///mydb?use_unicode=0')
-
-To not automatically use ``utf8`` and instead use whatever the connection
-defaults to, there is a separate parameter::
-
-  # use the default connection charset; all strings come back as unicode
-  create_engine('mysql+oursql:///mydb?default_charset=1')
-
-  # use latin1 as the connection charset; all strings come back as unicode
-  create_engine('mysql+oursql:///mydb?charset=latin1')

-.. dialect:: oracle
-    :name: Oracle
-
-    Oracle version 8 through current (11g at the time of this writing) are supported.
-
-Connect Arguments
------------------
-
-The dialect supports several :func:`~sqlalchemy.create_engine()` arguments which
-affect the behavior of the dialect regardless of driver in use.
-
-* ``use_ansi`` - Use ANSI JOIN constructs (see the section on Oracle 8).  Defaults
-  to ``True``.  If ``False``, Oracle-8 compatible constructs are used for joins.
-
-* ``optimize_limits`` - defaults to ``False``. see the section on LIMIT/OFFSET.
-
-* ``use_binds_for_limits`` - defaults to ``True``.  see the section on LIMIT/OFFSET.
-
-Auto Increment Behavior
------------------------
-
-SQLAlchemy Table objects which include integer primary keys are usually assumed to have
-"autoincrementing" behavior, meaning they can generate their own primary key values upon
-INSERT.  Since Oracle has no "autoincrement" feature, SQLAlchemy relies upon sequences
-to produce these values.   With the Oracle dialect, *a sequence must always be explicitly
-specified to enable autoincrement*.  This is divergent with the majority of documentation
-examples which assume the usage of an autoincrement-capable database.   To specify sequences,
-use the sqlalchemy.schema.Sequence object which is passed to a Column construct::
-
-  t = Table('mytable', metadata,
-        Column('id', Integer, Sequence('id_seq'), primary_key=True),
-        Column(...), ...
-  )
-
-This step is also required when using table reflection, i.e. autoload=True::
-
-  t = Table('mytable', metadata,
-        Column('id', Integer, Sequence('id_seq'), primary_key=True),
-        autoload=True
-  )
-
-Identifier Casing
------------------
-
-In Oracle, the data dictionary represents all case insensitive identifier names
-using UPPERCASE text.   SQLAlchemy on the other hand considers an all-lower case identifier
-name to be case insensitive.   The Oracle dialect converts all case insensitive identifiers
-to and from those two formats during schema level communication, such as reflection of
-tables and indexes.   Using an UPPERCASE name on the SQLAlchemy side indicates a
-case sensitive identifier, and SQLAlchemy will quote the name - this will cause mismatches
-against data dictionary data received from Oracle, so unless identifier names have been
-truly created as case sensitive (i.e. using quoted names), all lowercase names should be
-used on the SQLAlchemy side.
-
-
-LIMIT/OFFSET Support
---------------------
-
-Oracle has no support for the LIMIT or OFFSET keywords.  SQLAlchemy uses
-a wrapped subquery approach in conjunction with ROWNUM.  The exact methodology
-is taken from
-http://www.oracle.com/technology/oramag/oracle/06-sep/o56asktom.html .
-
-There are two options which affect its behavior:
-
-* the "FIRST ROWS()" optimization keyword is not used by default.  To enable the usage of this
-  optimization directive, specify ``optimize_limits=True`` to :func:`.create_engine`.
-* the values passed for the limit/offset are sent as bound parameters.   Some users have observed
-  that Oracle produces a poor query plan when the values are sent as binds and not
-  rendered literally.   To render the limit/offset values literally within the SQL
-  statement, specify ``use_binds_for_limits=False`` to :func:`.create_engine`.
-
-Some users have reported better performance when the entirely different approach of a
-window query is used, i.e. ROW_NUMBER() OVER (ORDER BY), to provide LIMIT/OFFSET (note
-that the majority of users don't observe this).  To suit this case the
-method used for LIMIT/OFFSET can be replaced entirely.  See the recipe at
-http://www.sqlalchemy.org/trac/wiki/UsageRecipes/WindowFunctionsByDefault
-which installs a select compiler that overrides the generation of limit/offset with
-a window function.
-
-.. _oracle_returning:
-
-RETURNING Support
------------------
-
-The Oracle database supports a limited form of RETURNING, in order to retrieve result
-sets of matched rows from INSERT, UPDATE and DELETE statements.  Oracle's
-RETURNING..INTO syntax only supports one row being returned, as it relies upon
-OUT parameters in order to function.  In addition, supported DBAPIs have further
-limitations (see :ref:`cx_oracle_returning`).
-
-SQLAlchemy's "implicit returning" feature, which employs RETURNING within an INSERT
-and sometimes an UPDATE statement in order to fetch newly generated primary key values
-and other SQL defaults and expressions, is normally enabled on the Oracle
-backend.  By default, "implicit returning" typically only fetches the value of a
-single ``nextval(some_seq)`` expression embedded into an INSERT in order to increment
-a sequence within an INSERT statement and get the value back at the same time.
-To disable this feature across the board, specify ``implicit_returning=False`` to
-:func:`.create_engine`::
-
-    engine = create_engine("oracle://scott:tiger@dsn", implicit_returning=False)
-
-Implicit returning can also be disabled on a table-by-table basis as a table option::
-
-    # Core Table
-    my_table = Table("my_table", metadata, ..., implicit_returning=False)
-
-
-    # declarative
-    class MyClass(Base):
-        __tablename__ = 'my_table'
-        __table_args__ = {"implicit_returning": False}
-
-.. seealso::
-
-    :ref:`cx_oracle_returning` - additional cx_oracle-specific restrictions on implicit returning.
-
-ON UPDATE CASCADE
------------------
-
-Oracle doesn't have native ON UPDATE CASCADE functionality.  A trigger based solution
-is available at http://asktom.oracle.com/tkyte/update_cascade/index.html .
-
-When using the SQLAlchemy ORM, the ORM has limited ability to manually issue
-cascading updates - specify ForeignKey objects using the
-"deferrable=True, initially='deferred'" keyword arguments,
-and specify "passive_updates=False" on each relationship().
-
-Oracle 8 Compatibility
-----------------------
-
-When Oracle 8 is detected, the dialect internally configures itself to the following
-behaviors:
-
-* the use_ansi flag is set to False.  This has the effect of converting all
-  JOIN phrases into the WHERE clause, and in the case of LEFT OUTER JOIN
-  makes use of Oracle's (+) operator.
-
-* the NVARCHAR2 and NCLOB datatypes are no longer generated as DDL when
-  the :class:`~sqlalchemy.types.Unicode` is used - VARCHAR2 and CLOB are issued
-  instead.   This because these types don't seem to work correctly on Oracle 8
-  even though they are available.  The :class:`~sqlalchemy.types.NVARCHAR`
-  and :class:`~sqlalchemy.dialects.oracle.NCLOB` types will always generate NVARCHAR2 and NCLOB.
-
-* the "native unicode" mode is disabled when using cx_oracle, i.e. SQLAlchemy
-  encodes all Python unicode objects to "string" before passing in as bind parameters.
-
-Synonym/DBLINK Reflection
--------------------------
-
-When using reflection with Table objects, the dialect can optionally search for tables
-indicated by synonyms, either in local or remote schemas or accessed over DBLINK,
-by passing the flag ``oracle_resolve_synonyms=True`` as a
-keyword argument to the :class:`.Table` construct::
-
-    some_table = Table('some_table', autoload=True,
-                                autoload_with=some_engine,
-                                oracle_resolve_synonyms=True)
-
-When this flag is set, the given name (such as ``some_table`` above) will
-be searched not just in the ``ALL_TABLES`` view, but also within the
-``ALL_SYNONYMS`` view to see if this name is actually a synonym to another name.
-If the synonym is located and refers to a DBLINK, the oracle dialect knows
-how to locate the table's information using DBLINK syntax (e.g. ``@dblink``).
-
-``oracle_resolve_synonyms`` is accepted wherever reflection arguments are
-accepted, including methods such as :meth:`.MetaData.reflect` and
-:meth:`.Inspector.get_columns`.
-
-If synonyms are not in use, this flag should be left disabled.
-
-DateTime Compatibility
-----------------------
-
-Oracle has no datatype known as ``DATETIME``, it instead has only ``DATE``,
-which can actually store a date and time value.  For this reason, the Oracle
-dialect provides a type :class:`.oracle.DATE` which is a subclass of
-:class:`.DateTime`.   This type has no special behavior, and is only
-present as a "marker" for this type; additionally, when a database column
-is reflected and the type is reported as ``DATE``, the time-supporting
-:class:`.oracle.DATE` type is used.
-
-.. versionchanged:: 0.9.4 Added :class:`.oracle.DATE` to subclass
-   :class:`.DateTime`.  This is a change as previous versions
-   would reflect a ``DATE`` column as :class:`.types.DATE`, which subclasses
-   :class:`.Date`.   The only significance here is for schemes that are
-   examining the type of column for use in special Python translations or
-   for migrating schemas to other database backends.

-Additional Connect Arguments
-----------------------------
-
-When connecting with ``dbname`` present, the host, port, and dbname tokens are
-converted to a TNS name using
-the cx_oracle ``makedsn()`` function.  Otherwise, the host token is taken
-directly as a TNS name.
-
-Additional arguments which may be specified either as query string arguments
-on the URL, or as keyword arguments to :func:`.create_engine()` are:
-
-* ``allow_twophase`` - enable two-phase transactions.  Defaults to ``True``.
-
-* ``arraysize`` - set the cx_oracle.arraysize value on cursors, defaulted
-  to 50.  This setting is significant with cx_Oracle as the contents of LOB
-  objects are only readable within a "live" row (e.g. within a batch of
-  50 rows).
-
-* ``auto_convert_lobs`` - defaults to True; See :ref:`cx_oracle_lob`.
-
-* ``auto_setinputsizes`` - the cx_oracle.setinputsizes() call is issued for
-  all bind parameters.  This is required for LOB datatypes but can be
-  disabled to reduce overhead.  Defaults to ``True``.  Specific types
-  can be excluded from this process using the ``exclude_setinputsizes``
-  parameter.
-
-* ``coerce_to_unicode`` - see :ref:`cx_oracle_unicode` for detail.
-
-* ``coerce_to_decimal`` - see :ref:`cx_oracle_numeric` for detail.
-
-* ``exclude_setinputsizes`` - a tuple or list of string DBAPI type names to
-  be excluded from the "auto setinputsizes" feature.  The type names here
-  must match DBAPI types that are found in the "cx_Oracle" module namespace,
-  such as cx_Oracle.UNICODE, cx_Oracle.NCLOB, etc.   Defaults to
-  ``(STRING, UNICODE)``.
-
-  .. versionadded:: 0.8 specific DBAPI types can be excluded from the
-     auto_setinputsizes feature via the exclude_setinputsizes attribute.
-
-* ``mode`` - This is given the string value of SYSDBA or SYSOPER, or alternatively
-  an integer value.  This value is only available as a URL query string
-  argument.
-
-* ``threaded`` - enable multithreaded access to cx_oracle connections.  Defaults
-  to ``True``.  Note that this is the opposite default of the cx_Oracle DBAPI
-  itself.
-
-.. _cx_oracle_unicode:
-
-Unicode
--------
-
-The cx_Oracle DBAPI as of version 5 fully supports unicode, and has the ability
-to return string results as Python unicode objects natively.
-
-When used in Python 3, cx_Oracle returns all strings as Python unicode objects
-(that is, plain ``str`` in Python 3).  In Python 2, it will return as Python
-unicode those column values that are of type ``NVARCHAR`` or ``NCLOB``.  For
-column values that are of type ``VARCHAR`` or other non-unicode string types,
-it will return values as Python strings (e.g. bytestrings).
-
-The cx_Oracle SQLAlchemy dialect presents two different options for the use case of
-returning ``VARCHAR`` column values as Python unicode objects under Python 2:
-
-* the cx_Oracle DBAPI has the ability to coerce all string results to Python
-  unicode objects unconditionally using output type handlers.  This has
-  the advantage that the unicode conversion is global to all statements
-  at the cx_Oracle driver level, meaning it works with raw textual SQL
-  statements that have no typing information associated.  However, this system
-  has been observed to incur signfiicant performance overhead, not only because
-  it takes effect for all string values unconditionally, but also because cx_Oracle under
-  Python 2 seems to use a pure-Python function call in order to do the
-  decode operation, which under cPython can orders of magnitude slower
-  than doing it using C functions alone.
-
-* SQLAlchemy has unicode-decoding services built in, and when using SQLAlchemy's
-  C extensions, these functions do not use any Python function calls and
-  are very fast.  The disadvantage to this approach is that the unicode
-  conversion only takes effect for statements where the :class:`.Unicode` type
-  or :class:`.String` type with ``convert_unicode=True`` is explicitly
-  associated with the result column.  This is the case for any ORM or Core
-  query or SQL expression as well as for a :func:`.text` construct that specifies
-  output column types, so in the vast majority of cases this is not an issue.
-  However, when sending a completely raw string to :meth:`.Connection.execute`,
-  this typing information isn't present, unless the string is handled
-  within a :func:`.text` construct that adds typing information.
-
-As of version 0.9.2 of SQLAlchemy, the default approach is to use SQLAlchemy's
-typing system.  This keeps cx_Oracle's expensive Python 2 approach
-disabled unless the user explicitly wants it.  Under Python 3, SQLAlchemy detects
-that cx_Oracle is returning unicode objects natively and cx_Oracle's system
-is used.
-
-To re-enable cx_Oracle's output type handler under Python 2, the
-``coerce_to_unicode=True`` flag (new in 0.9.4) can be passed to
-:func:`.create_engine`::
-
-    engine = create_engine("oracle+cx_oracle://dsn", coerce_to_unicode=True)
-
-Alternatively, to run a pure string SQL statement and get ``VARCHAR`` results
-as Python unicode under Python 2 without using cx_Oracle's native handlers,
-the :func:`.text` feature can be used::
-
-    from sqlalchemy import text, Unicode
-    result = conn.execute(text("select username from user").columns(username=Unicode))
-
-.. versionchanged:: 0.9.2 cx_Oracle's outputtypehandlers are no longer used for
-   unicode results of non-unicode datatypes in Python 2, after they were identified as a major
-   performance bottleneck.  SQLAlchemy's own unicode facilities are used
-   instead.
-
-.. versionadded:: 0.9.4 Added the ``coerce_to_unicode`` flag, to re-enable
-   cx_Oracle's outputtypehandler and revert to pre-0.9.2 behavior.
-
-.. _cx_oracle_returning:
-
-RETURNING Support
------------------
-
-The cx_oracle DBAPI supports a limited subset of Oracle's already limited RETURNING support.
-Typically, results can only be guaranteed for at most one column being returned;
-this is the typical case when SQLAlchemy uses RETURNING to get just the value of a
-primary-key-associated sequence value.    Additional column expressions will
-cause problems in a non-determinative way, due to cx_oracle's lack of support for
-the OCI_DATA_AT_EXEC API which is required for more complex RETURNING scenarios.
-
-For this reason, stability may be enhanced by disabling RETURNING support completely;
-SQLAlchemy otherwise will use RETURNING to fetch newly sequence-generated
-primary keys.  As illustrated in :ref:`oracle_returning`::
-
-    engine = create_engine("oracle://scott:tiger@dsn", implicit_returning=False)
-
-.. seealso::
-
-    http://docs.oracle.com/cd/B10501_01/appdev.920/a96584/oci05bnd.htm#420693 - OCI documentation for RETURNING
-
-    http://sourceforge.net/mailarchive/message.php?msg_id=31338136 - cx_oracle developer commentary
-
-.. _cx_oracle_lob:
-
-LOB Objects
------------
-
-cx_oracle returns oracle LOBs using the cx_oracle.LOB object.  SQLAlchemy converts
-these to strings so that the interface of the Binary type is consistent with that of
-other backends, and so that the linkage to a live cursor is not needed in scenarios
-like result.fetchmany() and result.fetchall().   This means that by default, LOB
-objects are fully fetched unconditionally by SQLAlchemy, and the linkage to a live
-cursor is broken.
-
-To disable this processing, pass ``auto_convert_lobs=False`` to :func:`.create_engine()`.
-
-Two Phase Transaction Support
------------------------------
-
-Two Phase transactions are implemented using XA transactions, and are known
-to work in a rudimental fashion with recent versions of cx_Oracle
-as of SQLAlchemy 0.8.0b2, 0.7.10.   However, the mechanism is not yet
-considered to be robust and should still be regarded as experimental.
-
-In particular, the cx_Oracle DBAPI as recently as 5.1.2 has a bug regarding
-two phase which prevents
-a particular DBAPI connection from being consistently usable in both
-prepared transactions as well as traditional DBAPI usage patterns; therefore
-once a particular connection is used via :meth:`.Connection.begin_prepared`,
-all subsequent usages of the underlying DBAPI connection must be within
-the context of prepared transactions.
-
-The default behavior of :class:`.Engine` is to maintain a pool of DBAPI
-connections.  Therefore, due to the above glitch, a DBAPI connection that has
-been used in a two-phase operation, and is then returned to the pool, will
-not be usable in a non-two-phase context.   To avoid this situation,
-the application can make one of several choices:
-
-* Disable connection pooling using :class:`.NullPool`
-
-* Ensure that the particular :class:`.Engine` in use is only used
-  for two-phase operations.   A :class:`.Engine` bound to an ORM
-  :class:`.Session` which includes ``twophase=True`` will consistently
-  use the two-phase transaction style.
-
-* For ad-hoc two-phase operations without disabling pooling, the DBAPI
-  connection in use can be evicted from the connection pool using the
-  :meth:`.Connection.detach` method.
-
-.. versionchanged:: 0.8.0b2,0.7.10
-    Support for cx_oracle prepared transactions has been implemented
-    and tested.
-
-.. _cx_oracle_numeric:
-
-Precision Numerics
-------------------
-
-The SQLAlchemy dialect goes through a lot of steps to ensure
-that decimal numbers are sent and received with full accuracy.
-An "outputtypehandler" callable is associated with each
-cx_oracle connection object which detects numeric types and
-receives them as string values, instead of receiving a Python
-``float`` directly, which is then passed to the Python
-``Decimal`` constructor.  The :class:`.Numeric` and
-:class:`.Float` types under the cx_oracle dialect are aware of
-this behavior, and will coerce the ``Decimal`` to ``float`` if
-the ``asdecimal`` flag is ``False`` (default on :class:`.Float`,
-optional on :class:`.Numeric`).
-
-Because the handler coerces to ``Decimal`` in all cases first,
-the feature can detract significantly from performance.
-If precision numerics aren't required, the decimal handling
-can be disabled by passing the flag ``coerce_to_decimal=False``
-to :func:`.create_engine`::
-
-    engine = create_engine("oracle+cx_oracle://dsn", coerce_to_decimal=False)
-
-.. versionadded:: 0.7.6
-    Add the ``coerce_to_decimal`` flag.
-
-Another alternative to performance is to use the
-`cdecimal <http://pypi.python.org/pypi/cdecimal/>`_ library;
-see :class:`.Numeric` for additional notes.
-
-The handler attempts to use the "precision" and "scale"
-attributes of the result set column to best determine if
-subsequent incoming values should be received as ``Decimal`` as
-opposed to int (in which case no processing is added). There are
-several scenarios where OCI_ does not provide unambiguous data
-as to the numeric type, including some situations where
-individual rows may return a combination of floating point and
-integer values. Certain values for "precision" and "scale" have
-been observed to determine this scenario.  When it occurs, the
-outputtypehandler receives as string and then passes off to a
-processing function which detects, for each returned value, if a
-decimal point is present, and if so converts to ``Decimal``,
-otherwise to int.  The intention is that simple int-based
-statements like "SELECT my_seq.nextval() FROM DUAL" continue to
-return ints and not ``Decimal`` objects, and that any kind of
-floating point value is received as a string so that there is no
-floating point loss of precision.
-
-The "decimal point is present" logic itself is also sensitive to
-locale.  Under OCI_, this is controlled by the NLS_LANG
-environment variable. Upon first connection, the dialect runs a
-test to determine the current "decimal" character, which can be
-a comma "," for european locales. From that point forward the
-outputtypehandler uses that character to represent a decimal
-point. Note that cx_oracle 5.0.3 or greater is required
-when dealing with numerics with locale settings that don't use
-a period "." as the decimal character.
-
-.. versionchanged:: 0.6.6
-    The outputtypehandler supports the case where the locale uses a
-    comma "," character to represent a decimal point.

-.. dialect:: postgresql
-    :name: PostgreSQL
-
-
-Sequences/SERIAL
-----------------
-
-PostgreSQL supports sequences, and SQLAlchemy uses these as the default means
-of creating new primary key values for integer-based primary key columns. When
-creating tables, SQLAlchemy will issue the ``SERIAL`` datatype for
-integer-based primary key columns, which generates a sequence and server side
-default corresponding to the column.
-
-To specify a specific named sequence to be used for primary key generation,
-use the :func:`~sqlalchemy.schema.Sequence` construct::
-
-    Table('sometable', metadata,
-            Column('id', Integer, Sequence('some_id_seq'), primary_key=True)
-        )
-
-When SQLAlchemy issues a single INSERT statement, to fulfill the contract of
-having the "last insert identifier" available, a RETURNING clause is added to
-the INSERT statement which specifies the primary key columns should be
-returned after the statement completes. The RETURNING functionality only takes
-place if Postgresql 8.2 or later is in use. As a fallback approach, the
-sequence, whether specified explicitly or implicitly via ``SERIAL``, is
-executed independently beforehand, the returned value to be used in the
-subsequent insert. Note that when an
-:func:`~sqlalchemy.sql.expression.insert()` construct is executed using
-"executemany" semantics, the "last inserted identifier" functionality does not
-apply; no RETURNING clause is emitted nor is the sequence pre-executed in this
-case.
-
-To force the usage of RETURNING by default off, specify the flag
-``implicit_returning=False`` to :func:`.create_engine`.
-
-.. _postgresql_isolation_level:
-
-Transaction Isolation Level
----------------------------
-
-All Postgresql dialects support setting of transaction isolation level
-both via a dialect-specific parameter ``isolation_level``
-accepted by :func:`.create_engine`,
-as well as the ``isolation_level`` argument as passed to :meth:`.Connection.execution_options`.
-When using a non-psycopg2 dialect, this feature works by issuing the
-command ``SET SESSION CHARACTERISTICS AS TRANSACTION ISOLATION LEVEL
-<level>`` for each new connection.
-
-To set isolation level using :func:`.create_engine`::
-
-    engine = create_engine(
-                    "postgresql+pg8000://scott:tiger@localhost/test",
-                    isolation_level="READ UNCOMMITTED"
-                )
-
-To set using per-connection execution options::
-
-    connection = engine.connect()
-    connection = connection.execution_options(isolation_level="READ COMMITTED")
-
-Valid values for ``isolation_level`` include:
-
-* ``READ COMMITTED``
-* ``READ UNCOMMITTED``
-* ``REPEATABLE READ``
-* ``SERIALIZABLE``
-
-The :mod:`~sqlalchemy.dialects.postgresql.psycopg2` dialect also offers the special level ``AUTOCOMMIT``.  See
-:ref:`psycopg2_isolation_level` for details.
-
-.. _postgresql_schema_reflection:
-
-Remote-Schema Table Introspection and Postgresql search_path
-------------------------------------------------------------
-
-The Postgresql dialect can reflect tables from any schema.  The
-:paramref:`.Table.schema` argument, or alternatively the
-:paramref:`.MetaData.reflect.schema` argument determines which schema will
-be searched for the table or tables.   The reflected :class:`.Table` objects
-will in all cases retain this ``.schema`` attribute as was specified.  However,
-with regards to tables which these :class:`.Table` objects refer to via
-foreign key constraint, a decision must be made as to how the ``.schema``
-is represented in those remote tables, in the case where that remote
-schema name is also a member of the current
-`Postgresql search path <http://www.postgresql.org/docs/9.0/static/ddl-schemas.html#DDL-SCHEMAS-PATH>`_.
-
-By default, the Postgresql dialect mimics the behavior encouraged by
-Postgresql's own ``pg_get_constraintdef()`` builtin procedure.  This function
-returns a sample definition for a particular foreign key constraint,
-omitting the referenced schema name from that definition when the name is
-also in the Postgresql schema search path.  The interaction below
-illustrates this behavior::
-
-    test=> CREATE TABLE test_schema.referred(id INTEGER PRIMARY KEY);
-    CREATE TABLE
-    test=> CREATE TABLE referring(
-    test(>         id INTEGER PRIMARY KEY,
-    test(>         referred_id INTEGER REFERENCES test_schema.referred(id));
-    CREATE TABLE
-    test=> SET search_path TO public, test_schema;
-    test=> SELECT pg_catalog.pg_get_constraintdef(r.oid, true) FROM
-    test-> pg_catalog.pg_class c JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
-    test-> JOIN pg_catalog.pg_constraint r  ON c.oid = r.conrelid
-    test-> WHERE c.relname='referring' AND r.contype = 'f'
-    test-> ;
-                   pg_get_constraintdef
-    ---------------------------------------------------
-     FOREIGN KEY (referred_id) REFERENCES referred(id)
-    (1 row)
-
-Above, we created a table ``referred`` as a member of the remote schema ``test_schema``, however
-when we added ``test_schema`` to the PG ``search_path`` and then asked ``pg_get_constraintdef()``
-for the ``FOREIGN KEY`` syntax, ``test_schema`` was not included in the
-output of the function.
-
-On the other hand, if we set the search path back to the typical default
-of ``public``::
-
-    test=> SET search_path TO public;
-    SET
-
-The same query against ``pg_get_constraintdef()`` now returns the fully
-schema-qualified name for us::
-
-    test=> SELECT pg_catalog.pg_get_constraintdef(r.oid, true) FROM
-    test-> pg_catalog.pg_class c JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
-    test-> JOIN pg_catalog.pg_constraint r  ON c.oid = r.conrelid
-    test-> WHERE c.relname='referring' AND r.contype = 'f';
-                         pg_get_constraintdef
-    ---------------------------------------------------------------
-     FOREIGN KEY (referred_id) REFERENCES test_schema.referred(id)
-    (1 row)
-
-SQLAlchemy will by default use the return value of ``pg_get_constraintdef()``
-in order to determine the remote schema name.  That is, if our ``search_path``
-were set to include ``test_schema``, and we invoked a table
-reflection process as follows::
-
-    >>> from sqlalchemy import Table, MetaData, create_engine
-    >>> engine = create_engine("postgresql://scott:tiger@localhost/test")
-    >>> with engine.connect() as conn:
-    ...     conn.execute("SET search_path TO test_schema, public")
-    ...     meta = MetaData()
-    ...     referring = Table('referring', meta, autoload=True, autoload_with=conn)
-    ...
-    <sqlalchemy.engine.result.ResultProxy object at 0x101612ed0>
-
-The above process would deliver to the :attr:`.MetaData.tables` collection
-``referred`` table named **without** the schema::
-
-    >>> meta.tables['referred'].schema is None
-    True
-
-To alter the behavior of reflection such that the referred schema is maintained
-regardless of the ``search_path`` setting, use the ``postgresql_ignore_search_path``
-option, which can be specified as a dialect-specific argument to both
-:class:`.Table` as well as :meth:`.MetaData.reflect`::
-
-    >>> with engine.connect() as conn:
-    ...     conn.execute("SET search_path TO test_schema, public")
-    ...     meta = MetaData()
-    ...     referring = Table('referring', meta, autoload=True, autoload_with=conn,
-    ...                     postgresql_ignore_search_path=True)
-    ...
-    <sqlalchemy.engine.result.ResultProxy object at 0x1016126d0>
-
-We will now have ``test_schema.referred`` stored as schema-qualified::
-
-    >>> meta.tables['test_schema.referred'].schema
-    'test_schema'
-
-.. sidebar:: Best Practices for Postgresql Schema reflection
-
-    The description of Postgresql schema reflection behavior is complex, and is
-    the product of many years of dealing with widely varied use cases and user preferences.
-    But in fact, there's no need to understand any of it if you just stick to the simplest
-    use pattern: leave the ``search_path`` set to its default of ``public`` only, never refer
-    to the name ``public`` as an explicit schema name otherwise, and
-    refer to all other schema names explicitly when building
-    up a :class:`.Table` object.  The options described here are only for those users
-    who can't, or prefer not to, stay within these guidelines.
-
-Note that **in all cases**, the "default" schema is always reflected as ``None``.
-The "default" schema on Postgresql is that which is returned by the
-Postgresql ``current_schema()`` function.  On a typical Postgresql installation,
-this is the name ``public``.  So a table that refers to another which is
-in the ``public`` (i.e. default) schema will always have the ``.schema`` attribute
-set to ``None``.
-
-.. versionadded:: 0.9.2 Added the ``postgresql_ignore_search_path``
-   dialect-level option accepted by :class:`.Table` and :meth:`.MetaData.reflect`.
-
-
-.. seealso::
-
-        `The Schema Search Path <http://www.postgresql.org/docs/9.0/static/ddl-schemas.html#DDL-SCHEMAS-PATH>`_ - on the Postgresql website.
-
-INSERT/UPDATE...RETURNING
--------------------------
-
-The dialect supports PG 8.2's ``INSERT..RETURNING``, ``UPDATE..RETURNING`` and
-``DELETE..RETURNING`` syntaxes.   ``INSERT..RETURNING`` is used by default
-for single-row INSERT statements in order to fetch newly generated
-primary key identifiers.   To specify an explicit ``RETURNING`` clause,
-use the :meth:`._UpdateBase.returning` method on a per-statement basis::
-
-    # INSERT..RETURNING
-    result = table.insert().returning(table.c.col1, table.c.col2).\\
-        values(name='foo')
-    print result.fetchall()
-
-    # UPDATE..RETURNING
-    result = table.update().returning(table.c.col1, table.c.col2).\\
-        where(table.c.name=='foo').values(name='bar')
-    print result.fetchall()
-
-    # DELETE..RETURNING
-    result = table.delete().returning(table.c.col1, table.c.col2).\\
-        where(table.c.name=='foo')
-    print result.fetchall()
-
-.. _postgresql_match:
-
-Full Text Search
-----------------
-
-SQLAlchemy makes available the Postgresql ``@@`` operator via the
-:meth:`.ColumnElement.match` method on any textual column expression.
-On a Postgresql dialect, an expression like the following::
-
-    select([sometable.c.text.match("search string")])
-
-will emit to the database::
-
-    SELECT text @@ to_tsquery('search string') FROM table
-
-The Postgresql text search functions such as ``to_tsquery()``
-and ``to_tsvector()`` are available
-explicitly using the standard :attr:`.func` construct.  For example::
-
-    select([
-        func.to_tsvector('fat cats ate rats').match('cat & rat')
-    ])
-
-Emits the equivalent of::
-
-    SELECT to_tsvector('fat cats ate rats') @@ to_tsquery('cat & rat')
-
-The :class:`.postgresql.TSVECTOR` type can provide for explicit CAST::
-
-    from sqlalchemy.dialects.postgresql import TSVECTOR
-    from sqlalchemy import select, cast
-    select([cast("some text", TSVECTOR)])
-
-produces a statement equivalent to::
-
-    SELECT CAST('some text' AS TSVECTOR) AS anon_1
-
-
-FROM ONLY ...
-------------------------
-
-The dialect supports PostgreSQL's ONLY keyword for targeting only a particular
-table in an inheritance hierarchy. This can be used to produce the
-``SELECT ... FROM ONLY``, ``UPDATE ONLY ...``, and ``DELETE FROM ONLY ...``
-syntaxes. It uses SQLAlchemy's hints mechanism::
-
-    # SELECT ... FROM ONLY ...
-    result = table.select().with_hint(table, 'ONLY', 'postgresql')
-    print result.fetchall()
-
-    # UPDATE ONLY ...
-    table.update(values=dict(foo='bar')).with_hint('ONLY',
-                                                   dialect_name='postgresql')
-
-    # DELETE FROM ONLY ...
-    table.delete().with_hint('ONLY', dialect_name='postgresql')
-
-.. _postgresql_indexes:
-
-Postgresql-Specific Index Options
----------------------------------
-
-Several extensions to the :class:`.Index` construct are available, specific
-to the PostgreSQL dialect.
-
-Partial Indexes
-^^^^^^^^^^^^^^^^
-
-Partial indexes add criterion to the index definition so that the index is
-applied to a subset of rows.   These can be specified on :class:`.Index`
-using the ``postgresql_where`` keyword argument::
-
-  Index('my_index', my_table.c.id, postgresql_where=tbl.c.value > 10)
-
-Operator Classes
-^^^^^^^^^^^^^^^^^
-
-PostgreSQL allows the specification of an *operator class* for each column of
-an index (see
-http://www.postgresql.org/docs/8.3/interactive/indexes-opclass.html).
-The :class:`.Index` construct allows these to be specified via the
-``postgresql_ops`` keyword argument::
-
-    Index('my_index', my_table.c.id, my_table.c.data,
-                            postgresql_ops={
-                                'data': 'text_pattern_ops',
-                                'id': 'int4_ops'
-                            })
-
-.. versionadded:: 0.7.2
-    ``postgresql_ops`` keyword argument to :class:`.Index` construct.
-
-Note that the keys in the ``postgresql_ops`` dictionary are the "key" name of
-the :class:`.Column`, i.e. the name used to access it from the ``.c``
-collection of :class:`.Table`, which can be configured to be different than
-the actual name of the column as expressed in the database.
-
-Index Types
-^^^^^^^^^^^^
-
-PostgreSQL provides several index types: B-Tree, Hash, GiST, and GIN, as well
-as the ability for users to create their own (see
-http://www.postgresql.org/docs/8.3/static/indexes-types.html). These can be
-specified on :class:`.Index` using the ``postgresql_using`` keyword argument::
-
-    Index('my_index', my_table.c.data, postgresql_using='gin')
-
-The value passed to the keyword argument will be simply passed through to the
-underlying CREATE INDEX command, so it *must* be a valid index type for your
-version of PostgreSQL.

-    SQL expressions of type :class:`.ARRAY` have support for "index" and
-    "slice" behavior.  The Python ``[]`` operator works normally here, given

-    for setting up type behavior.

-    The :class:`.JSON` type, when used with the SQLAlchemy ORM, does not detect

-    allow "in-place" changes to the datastructure to produce events which
-    will be detected by the unit of work.  See the example at :class:`.HSTORE`
-    for a simple example involving a dictionary.
-
-    Custom serializers and deserializers are specified at the dialect level,
-    that is using :func:`.create_engine`.  The reason for this is that when

-    :dbapi: psycopg2

-    :url: http://pypi.python.org/pypi/psycopg2/
-
-psycopg2 Connect Arguments
------------------------------------
-
-psycopg2-specific keyword arguments which are accepted by
-:func:`.create_engine()` are:
-
-* ``server_side_cursors``: Enable the usage of "server side cursors" for SQL
-  statements which support this feature. What this essentially means from a
-  psycopg2 point of view is that the cursor is created using a name, e.g.
-  ``connection.cursor('some name')``, which has the effect that result rows are
-  not immediately pre-fetched and buffered after statement execution, but are
-  instead left on the server and only retrieved as needed. SQLAlchemy's
-  :class:`~sqlalchemy.engine.ResultProxy` uses special row-buffering
-  behavior when this feature is enabled, such that groups of 100 rows at a
-  time are fetched over the wire to reduce conversational overhead.
-  Note that the ``stream_results=True`` execution option is a more targeted
-  way of enabling this mode on a per-execution basis.
-* ``use_native_unicode``: Enable the usage of Psycopg2 "native unicode" mode
-  per connection.  True by default.
-* ``isolation_level``: This option, available for all Posgtresql dialects,
-  includes the ``AUTOCOMMIT`` isolation level when using the psycopg2
-  dialect.  See :ref:`psycopg2_isolation_level`.
-
-
-Unix Domain Connections
-------------------------
-
-psycopg2 supports connecting via Unix domain connections.   When the ``host``
-portion of the URL is omitted, SQLAlchemy passes ``None`` to psycopg2,
-which specifies Unix-domain communication rather than TCP/IP communication::
-
-    create_engine("postgresql+psycopg2://user:password@/dbname")
-
-By default, the socket file used is to connect to a Unix-domain socket
-in ``/tmp``, or whatever socket directory was specified when PostgreSQL
-was built.  This value can be overridden by passing a pathname to psycopg2,
-using ``host`` as an additional keyword argument::
-
-    create_engine("postgresql+psycopg2://user:password@/dbname?host=/var/lib/postgresql")
-
-See also:
-
-`PQconnectdbParams <http://www.postgresql.org/docs/9.1/static/libpq-connect.html#LIBPQ-PQCONNECTDBPARAMS>`_
-
-Per-Statement/Connection Execution Options
--------------------------------------------
-
-The following DBAPI-specific options are respected when used with
-:meth:`.Connection.execution_options`, :meth:`.Executable.execution_options`,
-:meth:`.Query.execution_options`, in addition to those not specific to DBAPIs:
-
-* isolation_level - Set the transaction isolation level for the lifespan of a
-  :class:`.Connection` (can only be set on a connection, not a statement
-  or query).   See :ref:`psycopg2_isolation_level`.
-
-* stream_results - Enable or disable usage of psycopg2 server side cursors -
-  this feature makes use of "named" cursors in combination with special
-  result handling methods so that result rows are not fully buffered.
-  If ``None`` or not set, the ``server_side_cursors`` option of the
-  :class:`.Engine` is used.
-
-Unicode
--------
-
-By default, the psycopg2 driver uses the ``psycopg2.extensions.UNICODE``
-extension, such that the DBAPI receives and returns all strings as Python
-Unicode objects directly - SQLAlchemy passes these values through without
-change.   Psycopg2 here will encode/decode string values based on the
-current "client encoding" setting; by default this is the value in
-the ``postgresql.conf`` file, which often defaults to ``SQL_ASCII``.
-Typically, this can be changed to ``utf-8``, as a more useful default::
-
-    #client_encoding = sql_ascii # actually, defaults to database
-                                 # encoding
-    client_encoding = utf8
-
-A second way to affect the client encoding is to set it within Psycopg2
-locally.   SQLAlchemy will call psycopg2's ``set_client_encoding()``
-method (see: http://initd.org/psycopg/docs/connection.html#connection.set_client_encoding)
-on all new connections based on the value passed to
-:func:`.create_engine` using the ``client_encoding`` parameter::
-
-    engine = create_engine("postgresql://user:pass@host/dbname", client_encoding='utf8')
-
-This overrides the encoding specified in the Postgresql client configuration.
-
-.. versionadded:: 0.7.3
-    The psycopg2-specific ``client_encoding`` parameter to
-    :func:`.create_engine`.
-
-SQLAlchemy can also be instructed to skip the usage of the psycopg2
-``UNICODE`` extension and to instead utilize it's own unicode encode/decode
-services, which are normally reserved only for those DBAPIs that don't
-fully support unicode directly.  Passing ``use_native_unicode=False`` to
-:func:`.create_engine` will disable usage of ``psycopg2.extensions.UNICODE``.
-SQLAlchemy will instead encode data itself into Python bytestrings on the way
-in and coerce from bytes on the way back,
-using the value of the :func:`.create_engine` ``encoding`` parameter, which
-defaults to ``utf-8``.
-SQLAlchemy's own unicode encode/decode functionality is steadily becoming
-obsolete as more DBAPIs support unicode fully along with the approach of
-Python 3; in modern usage psycopg2 should be relied upon to handle unicode.
-
-Transactions
-------------
-
-The psycopg2 dialect fully supports SAVEPOINT and two-phase commit operations.
-
-.. _psycopg2_isolation_level:
-
-Psycopg2 Transaction Isolation Level
--------------------------------------
-
-As discussed in :ref:`postgresql_isolation_level`,
-all Postgresql dialects support setting of transaction isolation level
-both via the ``isolation_level`` parameter passed to :func:`.create_engine`,
-as well as the ``isolation_level`` argument used by :meth:`.Connection.execution_options`.
-When using the psycopg2 dialect, these options make use of
-psycopg2's ``set_isolation_level()`` connection method, rather than
-emitting a Postgresql directive; this is because psycopg2's API-level
-setting is always emitted at the start of each transaction in any case.
-
-The psycopg2 dialect supports these constants for isolation level:
-
-* ``READ COMMITTED``
-* ``READ UNCOMMITTED``
-* ``REPEATABLE READ``
-* ``SERIALIZABLE``
-* ``AUTOCOMMIT``
-
-.. versionadded:: 0.8.2 support for AUTOCOMMIT isolation level when using
-   psycopg2.
-
-
-NOTICE logging
----------------
-
-The psycopg2 dialect will log Postgresql NOTICE messages via the
-``sqlalchemy.dialects.postgresql`` logger::
-
-    import logging
-    logging.getLogger('sqlalchemy.dialects.postgresql').setLevel(logging.INFO)
-
-.. _psycopg2_hstore::
-
-HSTORE type
-------------
-
-The ``psycopg2`` DBAPI includes an extension to natively handle marshalling of the
-HSTORE type.   The SQLAlchemy psycopg2 dialect will enable this extension
-by default when it is detected that the target database has the HSTORE
-type set up for use.   In other words, when the dialect makes the first
-connection, a sequence like the following is performed:
-
-1. Request the available HSTORE oids using ``psycopg2.extras.HstoreAdapter.get_oids()``.
-   If this function returns a list of HSTORE identifiers, we then determine that
-   the ``HSTORE`` extension is present.
-
-2. If the ``use_native_hstore`` flag is at it's default of ``True``, and
-   we've detected that ``HSTORE`` oids are available, the
-   ``psycopg2.extensions.register_hstore()`` extension is invoked for all
-   connections.
-
-The ``register_hstore()`` extension has the effect of **all Python dictionaries
-being accepted as parameters regardless of the type of target column in SQL**.
-The dictionaries are converted by this extension into a textual HSTORE expression.
-If this behavior is not desired, disable the
-use of the hstore extension by setting ``use_native_hstore`` to ``False`` as follows::
-
-    engine = create_engine("postgresql+psycopg2://scott:tiger@localhost/test",
-                use_native_hstore=False)
-
-The ``HSTORE`` type is **still supported** when the ``psycopg2.extensions.register_hstore()``
-extension is not used.  It merely means that the coercion between Python dictionaries and the HSTORE
-string format, on both the parameter side and the result side, will take
-place within SQLAlchemy's own marshalling logic, and not that of ``psycopg2`` which
-may be more performant.

-.. dialect:: sqlite
-    :name: SQLite
-
-
-Date and Time Types
--------------------
-
-SQLite does not have built-in DATE, TIME, or DATETIME types, and pysqlite does
-not provide out of the box functionality for translating values between Python
-`datetime` objects and a SQLite-supported format. SQLAlchemy's own
-:class:`~sqlalchemy.types.DateTime` and related types provide date formatting
-and parsing functionality when SQlite is used. The implementation classes are
-:class:`~.sqlite.DATETIME`, :class:`~.sqlite.DATE` and :class:`~.sqlite.TIME`.
-These types represent dates and times as ISO formatted strings, which also
-nicely support ordering. There's no reliance on typical "libc" internals for
-these functions so historical dates are fully supported.
-
-Auto Incrementing Behavior
---------------------------
-
-Background on SQLite's autoincrement is at: http://sqlite.org/autoinc.html
-
-Two things to note:
-
-* The AUTOINCREMENT keyword is **not** required for SQLite tables to
-  generate primary key values automatically. AUTOINCREMENT only means that the
-  algorithm used to generate ROWID values should be slightly different.
-* SQLite does **not** generate primary key (i.e. ROWID) values, even for
-  one column, if the table has a composite (i.e. multi-column) primary key.
-  This is regardless of the AUTOINCREMENT keyword being present or not.
-
-To specifically render the AUTOINCREMENT keyword on the primary key column when
-rendering DDL, add the flag ``sqlite_autoincrement=True`` to the Table
-construct::
-
-    Table('sometable', metadata,
-            Column('id', Integer, primary_key=True),
-            sqlite_autoincrement=True)
-
-Transaction Isolation Level
----------------------------
-
-:func:`.create_engine` accepts an ``isolation_level`` parameter which results
-in the command ``PRAGMA read_uncommitted <level>`` being invoked for every new
-connection. Valid values for this parameter are ``SERIALIZABLE`` and ``READ
-UNCOMMITTED`` corresponding to a value of 0 and 1, respectively. See the
-section :ref:`pysqlite_serializable` for an important workaround when using
-serializable isolation with Pysqlite.
-
-Database Locking Behavior / Concurrency
----------------------------------------
-
-Note that SQLite is not designed for a high level of concurrency. The database
-itself, being a file, is locked completely during write operations and within
-transactions, meaning exactly one connection has exclusive access to the
-database during this period - all other connections will be blocked during this
-time.
-
-The Python DBAPI specification also calls for a connection model that is always
-in a transaction; there is no BEGIN method, only commit and rollback. This
-implies that a SQLite DBAPI driver would technically allow only serialized
-access to a particular database file at all times. The pysqlite driver attempts
-to ameliorate this by deferring the actual BEGIN statement until the first DML
-(INSERT, UPDATE, or DELETE) is received within a transaction. While this breaks
-serializable isolation, it at least delays the exclusive locking inherent in
-SQLite's design.
-
-SQLAlchemy's default mode of usage with the ORM is known as "autocommit=False",
-which means the moment the :class:`.Session` begins to be used, a transaction
-is begun. As the :class:`.Session` is used, the autoflush feature, also on by
-default, will flush out pending changes to the database before each query. The
-effect of this is that a :class:`.Session` used in its default mode will often
-emit DML early on, long before the transaction is actually committed. This
-again will have the effect of serializing access to the SQLite database. If
-highly concurrent reads are desired against the SQLite database, it is advised
-that the autoflush feature be disabled, and potentially even that autocommit be
-re-enabled, which has the effect of each SQL statement and flush committing
-changes immediately.
-
-For more information on SQLite's lack of concurrency by design, please see
-`Situations Where Another RDBMS May Work Better - High Concurrency
-<http://www.sqlite.org/whentouse.html>`_ near the bottom of the page.
-
-.. _sqlite_foreign_keys:
-
-Foreign Key Support
--------------------
-
-SQLite supports FOREIGN KEY syntax when emitting CREATE statements for tables,
-however by default these constraints have no effect on the operation of the
-table.
-
-Constraint checking on SQLite has three prerequisites:
-
-* At least version 3.6.19 of SQLite must be in use
-* The SQLite libary must be compiled *without* the SQLITE_OMIT_FOREIGN_KEY
-  or SQLITE_OMIT_TRIGGER symbols enabled.
-* The ``PRAGMA foreign_keys = ON`` statement must be emitted on all connections
-  before use.
-
-SQLAlchemy allows for the ``PRAGMA`` statement to be emitted automatically for
-new connections through the usage of events::
-
-    from sqlalchemy.engine import Engine
-    from sqlalchemy import event
-
-    @event.listens_for(Engine, "connect")
-    def set_sqlite_pragma(dbapi_connection, connection_record):
-        cursor = dbapi_connection.cursor()
-        cursor.execute("PRAGMA foreign_keys=ON")
-        cursor.close()
-
-.. seealso::
-
-    `SQLite Foreign Key Support <http://www.sqlite.org/foreignkeys.html>`_ - on
-    the SQLite web site.
-
-    :ref:`event_toplevel` - SQLAlchemy event API.
-
-.. _sqlite_type_reflection:
-
-Type Reflection
----------------
-
-SQLite types are unlike those of most other database backends, in that
-the string name of the type usually does not correspond to a "type" in a
-one-to-one fashion.  Instead, SQLite links per-column typing behavior
-to one of five so-called "type affinities" based on a string matching
-pattern for the type.
-
-SQLAlchemy's reflection process, when inspecting types, uses a simple
-lookup table to link the keywords returned to provided SQLAlchemy types.
-This lookup table is present within the SQLite dialect as it is for all
-other dialects.  However, the SQLite dialect has a different "fallback"
-routine for when a particular type name is not located in the lookup map;
-it instead implements the SQLite "type affinity" scheme located at
-http://www.sqlite.org/datatype3.html section 2.1.
-
-The provided typemap will make direct associations from an exact string
-name match for the following types:
-
-:class:`~.types.BIGINT`, :class:`~.types.BLOB`,
-:class:`~.types.BOOLEAN`, :class:`~.types.BOOLEAN`,
-:class:`~.types.CHAR`, :class:`~.types.DATE`,
-:class:`~.types.DATETIME`, :class:`~.types.FLOAT`,
-:class:`~.types.DECIMAL`, :class:`~.types.FLOAT`,
-:class:`~.types.INTEGER`, :class:`~.types.INTEGER`,
-:class:`~.types.NUMERIC`, :class:`~.types.REAL`,
-:class:`~.types.SMALLINT`, :class:`~.types.TEXT`,
-:class:`~.types.TIME`, :class:`~.types.TIMESTAMP`,
-:class:`~.types.VARCHAR`, :class:`~.types.NVARCHAR`,
-:class:`~.types.NCHAR`
-
-When a type name does not match one of the above types, the "type affinity"
-lookup is used instead:
-
-* :class:`~.types.INTEGER` is returned if the type name includes the
-  string ``INT``
-* :class:`~.types.TEXT` is returned if the type name includes the
-  string ``CHAR``, ``CLOB`` or ``TEXT``
-* :class:`~.types.NullType` is returned if the type name includes the
-  string ``BLOB``
-* :class:`~.types.REAL` is returned if the type name includes the string
-  ``REAL``, ``FLOA`` or ``DOUB``.
-* Otherwise, the :class:`~.types.NUMERIC` type is used.
-
-.. versionadded:: 0.9.3 Support for SQLite type affinity rules when reflecting
-   columns.

-.. dialect:: sqlite+pysqlite
-    :name: pysqlite
-    :dbapi: sqlite3
-    :connectstring: sqlite+pysqlite:///file_path
-    :url: http://docs.python.org/library/sqlite3.html
-
-    Note that ``pysqlite`` is the same driver as the ``sqlite3``
-    module included with the Python distribution.
-
-Driver
-------
-
-When using Python 2.5 and above, the built in ``sqlite3`` driver is
-already installed and no additional installation is needed.  Otherwise,
-the ``pysqlite2`` driver needs to be present.  This is the same driver as
-``sqlite3``, just with a different name.
-
-The ``pysqlite2`` driver will be loaded first, and if not found, ``sqlite3``
-is loaded.  This allows an explicitly installed pysqlite driver to take
-precedence over the built in one.   As with all dialects, a specific
-DBAPI module may be provided to :func:`~sqlalchemy.create_engine()` to control
-this explicitly::
-
-    from sqlite3 import dbapi2 as sqlite
-    e = create_engine('sqlite+pysqlite:///file.db', module=sqlite)
-
-
-Connect Strings
----------------
-
-The file specification for the SQLite database is taken as the "database"
-portion of the URL.  Note that the format of a SQLAlchemy url is::
-
-    driver://user:pass@host/database
-
-This means that the actual filename to be used starts with the characters to
-the **right** of the third slash.   So connecting to a relative filepath
-looks like::
-
-    # relative path
-    e = create_engine('sqlite:///path/to/database.db')
-
-An absolute path, which is denoted by starting with a slash, means you
-need **four** slashes::
-
-    # absolute path
-    e = create_engine('sqlite:////path/to/database.db')
-
-To use a Windows path, regular drive specifications and backslashes can be
-used. Double backslashes are probably needed::
-
-    # absolute path on Windows
-    e = create_engine('sqlite:///C:\\\\path\\\\to\\\\database.db')
-
-The sqlite ``:memory:`` identifier is the default if no filepath is
-present.  Specify ``sqlite://`` and nothing else::
-
-    # in-memory database
-    e = create_engine('sqlite://')
-
-Compatibility with sqlite3 "native" date and datetime types
------------------------------------------------------------
-
-The pysqlite driver includes the sqlite3.PARSE_DECLTYPES and
-sqlite3.PARSE_COLNAMES options, which have the effect of any column
-or expression explicitly cast as "date" or "timestamp" will be converted
-to a Python date or datetime object.  The date and datetime types provided
-with the pysqlite dialect are not currently compatible with these options,
-since they render the ISO date/datetime including microseconds, which
-pysqlite's driver does not.   Additionally, SQLAlchemy does not at
-this time automatically render the "cast" syntax required for the
-freestanding functions "current_timestamp" and "current_date" to return
-datetime/date types natively.   Unfortunately, pysqlite
-does not provide the standard DBAPI types in ``cursor.description``,
-leaving SQLAlchemy with no way to detect these types on the fly
-without expensive per-row type checks.
-
-Keeping in mind that pysqlite's parsing option is not recommended,
-nor should be necessary, for use with SQLAlchemy, usage of PARSE_DECLTYPES
-can be forced if one configures "native_datetime=True" on create_engine()::
-
-    engine = create_engine('sqlite://',
-        connect_args={'detect_types': sqlite3.PARSE_DECLTYPES|sqlite3.PARSE_COLNAMES},
-        native_datetime=True
-    )
-
-With this flag enabled, the DATE and TIMESTAMP types (but note - not the
-DATETIME or TIME types...confused yet ?) will not perform any bind parameter
-or result processing. Execution of "func.current_date()" will return a string.
-"func.current_timestamp()" is registered as returning a DATETIME type in
-SQLAlchemy, so this function still receives SQLAlchemy-level result processing.
-
-.. _pysqlite_threading_pooling:
-
-Threading/Pooling Behavior
----------------------------
-
-Pysqlite's default behavior is to prohibit the usage of a single connection
-in more than one thread.   This is originally intended to work with older
-versions of SQLite that did not support multithreaded operation under
-various circumstances.  In particular, older SQLite versions
-did not allow a ``:memory:`` database to be used in multiple threads
-under any circumstances.
-
-Pysqlite does include a now-undocumented flag known as
-``check_same_thread`` which will disable this check, however note that pysqlite
-connections are still not safe to use in concurrently in multiple threads.
-In particular, any statement execution calls would need to be externally
-mutexed, as Pysqlite does not provide for thread-safe propagation of error
-messages among other things.   So while even ``:memory:`` databases can be
-shared among threads in modern SQLite, Pysqlite doesn't provide enough
-thread-safety to make this usage worth it.
-
-SQLAlchemy sets up pooling to work with Pysqlite's default behavior:
-
-* When a ``:memory:`` SQLite database is specified, the dialect by default
-  will use :class:`.SingletonThreadPool`. This pool maintains a single
-  connection per thread, so that all access to the engine within the current
-  thread use the same ``:memory:`` database - other threads would access a
-  different ``:memory:`` database.
-* When a file-based database is specified, the dialect will use
-  :class:`.NullPool` as the source of connections. This pool closes and
-  discards connections which are returned to the pool immediately. SQLite
-  file-based connections have extremely low overhead, so pooling is not
-  necessary. The scheme also prevents a connection from being used again in
-  a different thread and works best with SQLite's coarse-grained file locking.
-
-  .. versionchanged:: 0.7
-      Default selection of :class:`.NullPool` for SQLite file-based databases.
-      Previous versions select :class:`.SingletonThreadPool` by
-      default for all SQLite databases.
-
-
-Using a Memory Database in Multiple Threads
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-To use a ``:memory:`` database in a multithreaded scenario, the same connection
-object must be shared among threads, since the database exists
-only within the scope of that connection.   The
-:class:`.StaticPool` implementation will maintain a single connection
-globally, and the ``check_same_thread`` flag can be passed to Pysqlite
-as ``False``::
-
-    from sqlalchemy.pool import StaticPool
-    engine = create_engine('sqlite://',
-                        connect_args={'check_same_thread':False},
-                        poolclass=StaticPool)
-
-Note that using a ``:memory:`` database in multiple threads requires a recent
-version of SQLite.
-
-Using Temporary Tables with SQLite
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Due to the way SQLite deals with temporary tables, if you wish to use a
-temporary table in a file-based SQLite database across multiple checkouts
-from the connection pool, such as when using an ORM :class:`.Session` where
-the temporary table should continue to remain after :meth:`.Session.commit` or
-:meth:`.Session.rollback` is called, a pool which maintains a single connection must
-be used.   Use :class:`.SingletonThreadPool` if the scope is only needed
-within the current thread, or :class:`.StaticPool` is scope is needed within
-multiple threads for this case::
-
-    # maintain the same connection per thread
-    from sqlalchemy.pool import SingletonThreadPool
-    engine = create_engine('sqlite:///mydb.db',
-                        poolclass=SingletonThreadPool)
-
-
-    # maintain the same connection across all threads
-    from sqlalchemy.pool import StaticPool
-    engine = create_engine('sqlite:///mydb.db',
-                        poolclass=StaticPool)
-
-Note that :class:`.SingletonThreadPool` should be configured for the number
-of threads that are to be used; beyond that number, connections will be
-closed out in a non deterministic way.
-
-Unicode
--------
-
-The pysqlite driver only returns Python ``unicode`` objects in result sets,
-never plain strings, and accommodates ``unicode`` objects within bound
-parameter values in all cases.   Regardless of the SQLAlchemy string type in
-use, string-based result values will by Python ``unicode`` in Python 2.
-The :class:`.Unicode` type should still be used to indicate those columns that
-require unicode, however, so that non-``unicode`` values passed inadvertently
-will emit a warning.  Pysqlite will emit an error if a non-``unicode`` string
-is passed containing non-ASCII characters.
-
-.. _pysqlite_serializable:
-
-Serializable Transaction Isolation
-----------------------------------
-
-The pysqlite DBAPI driver has a long-standing bug in which transactional
-state is not begun until the first DML statement, that is INSERT, UPDATE
-or DELETE, is emitted.  A SELECT statement will not cause transactional
-state to begin.   While this mode of usage is fine for typical situations
-and has the advantage that the SQLite database file is not prematurely
-locked, it breaks serializable transaction isolation, which requires
-that the database file be locked upon any SQL being emitted.
-
-To work around this issue, the ``BEGIN`` keyword can be emitted
-at the start of each transaction.   The following recipe establishes
-a :meth:`.ConnectionEvents.begin` handler to achieve this::
-
-    from sqlalchemy import create_engine, event
-
-    engine = create_engine("sqlite:///myfile.db", isolation_level='SERIALIZABLE')
-
-    @event.listens_for(engine, "begin")
-    def do_begin(conn):
-        conn.execute("BEGIN")

-"""SQL connections, SQL execution and high-level DB-API interface.
-
-The engine package defines the basic components used to interface
-DB-API modules with higher-level statement construction,
-connection-management, execution and result contexts.  The primary
-"entry point" class into this package is the Engine and it's public
-constructor ``create_engine()``.
-
-This package includes:
-
-base.py
-    Defines interface classes and some implementation classes which
-    comprise the basic components used to interface between a DB-API,
-    constructed and plain-text statements, connections, transactions,
-    and results.
-
-default.py
-    Contains default implementations of some of the components defined
-    in base.py.  All current database dialects use the classes in
-    default.py as base classes for their own database-specific
-    implementations.
-
-strategies.py
-    The mechanics of constructing ``Engine`` objects are represented
-    here.  Defines the ``EngineStrategy`` class which represents how
-    to go from arguments specified to the ``create_engine()``
-    function, to a fully constructed ``Engine``, including
-    initialization of connection pooling, dialects, and specific
-    subclasses of ``Engine``.
-
-threadlocal.py
-    The ``TLEngine`` class is defined here, which is a subclass of
-    the generic ``Engine`` and tracks ``Connection`` and
-    ``Transaction`` objects against the identity of the current
-    thread.  This allows certain programming patterns based around
-    the concept of a "thread-local connection" to be possible.
-    The ``TLEngine`` is created by using the "threadlocal" engine
-    strategy in conjunction with the ``create_engine()`` function.
-
-url.py
-    Defines the ``URL`` class which represents the individual
-    components of a string URL passed to ``create_engine()``.  Also
-    defines a basic module-loading strategy for the dialect specifier
-    within a URL.

-def create_engine(*args, **kwargs):
-    """Create a new :class:`.Engine` instance.
-
-    The standard calling form is to send the URL as the
-    first positional argument, usually a string
-    that indicates database dialect and connection arguments::
-
-
-        engine = create_engine("postgresql://scott:tiger@localhost/test")
-
-    Additional keyword arguments may then follow it which
-    establish various options on the resulting :class:`.Engine`
-    and its underlying :class:`.Dialect` and :class:`.Pool`
-    constructs::
-
-        engine = create_engine("mysql://scott:tiger@hostname/dbname",
-                                    encoding='latin1', echo=True)
-
-    The string form of the URL is
-    ``dialect[+driver]://user:password@host/dbname[?key=value..]``, where
-    ``dialect`` is a database name such as ``mysql``, ``oracle``,
-    ``postgresql``, etc., and ``driver`` the name of a DBAPI, such as
-    ``psycopg2``, ``pyodbc``, ``cx_oracle``, etc.  Alternatively,
-    the URL can be an instance of :class:`~sqlalchemy.engine.url.URL`.
-
-    ``**kwargs`` takes a wide variety of options which are routed
-    towards their appropriate components.  Arguments may be specific to
-    the :class:`.Engine`, the underlying :class:`.Dialect`, as well as the
-    :class:`.Pool`.  Specific dialects also accept keyword arguments that
-    are unique to that dialect.   Here, we describe the parameters
-    that are common to most :func:`.create_engine()` usage.
-
-    Once established, the newly resulting :class:`.Engine` will
-    request a connection from the underlying :class:`.Pool` once
-    :meth:`.Engine.connect` is called, or a method which depends on it
-    such as :meth:`.Engine.execute` is invoked.   The :class:`.Pool` in turn
-    will establish the first actual DBAPI connection when this request
-    is received.   The :func:`.create_engine` call itself does **not**
-    establish any actual DBAPI connections directly.
-
-    .. seealso::
-
-        :doc:`/core/engines`
-
-        :doc:`/dialects/index`
-
-        :ref:`connections_toplevel`
-
-    :param case_sensitive=True: if False, result column names
-       will match in a case-insensitive fashion, that is,
-       ``row['SomeColumn']``.
-
-       .. versionchanged:: 0.8
-           By default, result row names match case-sensitively.
-           In version 0.7 and prior, all matches were case-insensitive.
-
-    :param connect_args: a dictionary of options which will be
-        passed directly to the DBAPI's ``connect()`` method as
-        additional keyword arguments.  See the example
-        at :ref:`custom_dbapi_args`.
-
-    :param convert_unicode=False: if set to True, sets
-        the default behavior of ``convert_unicode`` on the
-        :class:`.String` type to ``True``, regardless
-        of a setting of ``False`` on an individual
-        :class:`.String` type, thus causing all :class:`.String`
-        -based columns
-        to accommodate Python ``unicode`` objects.  This flag
-        is useful as an engine-wide setting when using a
-        DBAPI that does not natively support Python
-        ``unicode`` objects and raises an error when
-        one is received (such as pyodbc with FreeTDS).
-
-        See :class:`.String` for further details on
-        what this flag indicates.
-
-    :param creator: a callable which returns a DBAPI connection.
-        This creation function will be passed to the underlying
-        connection pool and will be used to create all new database
-        connections. Usage of this function causes connection
-        parameters specified in the URL argument to be bypassed.
-
-    :param echo=False: if True, the Engine will log all statements
-        as well as a repr() of their parameter lists to the engines
-        logger, which defaults to sys.stdout. The ``echo`` attribute of
-        ``Engine`` can be modified at any time to turn logging on and
-        off. If set to the string ``"debug"``, result rows will be
-        printed to the standard output as well. This flag ultimately
-        controls a Python logger; see :ref:`dbengine_logging` for
-        information on how to configure logging directly.
-
-    :param echo_pool=False: if True, the connection pool will log
-        all checkouts/checkins to the logging stream, which defaults to
-        sys.stdout. This flag ultimately controls a Python logger; see
-        :ref:`dbengine_logging` for information on how to configure logging
-        directly.
-
-    :param encoding: Defaults to ``utf-8``.  This is the string
-        encoding used by SQLAlchemy for string encode/decode
-        operations which occur within SQLAlchemy, **outside of
-        the DBAPI.**  Most modern DBAPIs feature some degree of
-        direct support for Python ``unicode`` objects,
-        what you see in Python 2 as a string of the form
-        ``u'some string'``.  For those scenarios where the
-        DBAPI is detected as not supporting a Python ``unicode``
-        object, this encoding is used to determine the
-        source/destination encoding.  It is **not used**
-        for those cases where the DBAPI handles unicode
-        directly.
-
-        To properly configure a system to accommodate Python
-        ``unicode`` objects, the DBAPI should be
-        configured to handle unicode to the greatest
-        degree as is appropriate - see
-        the notes on unicode pertaining to the specific
-        target database in use at :ref:`dialect_toplevel`.
-
-        Areas where string encoding may need to be accommodated
-        outside of the DBAPI include zero or more of:
-
-        * the values passed to bound parameters, corresponding to
-          the :class:`.Unicode` type or the :class:`.String` type
-          when ``convert_unicode`` is ``True``;
-        * the values returned in result set columns corresponding
-          to the :class:`.Unicode` type or the :class:`.String`
-          type when ``convert_unicode`` is ``True``;
-        * the string SQL statement passed to the DBAPI's
-          ``cursor.execute()`` method;
-        * the string names of the keys in the bound parameter
-          dictionary passed to the DBAPI's ``cursor.execute()``
-          as well as ``cursor.setinputsizes()`` methods;
-        * the string column names retrieved from the DBAPI's
-          ``cursor.description`` attribute.
-
-        When using Python 3, the DBAPI is required to support
-        *all* of the above values as Python ``unicode`` objects,
-        which in Python 3 are just known as ``str``.  In Python 2,
-        the DBAPI does not specify unicode behavior at all,
-        so SQLAlchemy must make decisions for each of the above
-        values on a per-DBAPI basis - implementations are
-        completely inconsistent in their behavior.
-
-    :param execution_options: Dictionary execution options which will
-        be applied to all connections.  See
-        :meth:`~sqlalchemy.engine.Connection.execution_options`
-
-    :param implicit_returning=True: When ``True``, a RETURNING-
-        compatible construct, if available, will be used to
-        fetch newly generated primary key values when a single row
-        INSERT statement is emitted with no existing returning()
-        clause.  This applies to those backends which support RETURNING
-        or a compatible construct, including Postgresql, Firebird, Oracle,
-        Microsoft SQL Server.   Set this to ``False`` to disable
-        the automatic usage of RETURNING.
-
-    :param label_length=None: optional integer value which limits
-        the size of dynamically generated column labels to that many
-        characters. If less than 6, labels are generated as
-        "_(counter)". If ``None``, the value of
-        ``dialect.max_identifier_length`` is used instead.
-
-    :param listeners: A list of one or more
-        :class:`~sqlalchemy.interfaces.PoolListener` objects which will
-        receive connection pool events.
-
-    :param logging_name:  String identifier which will be used within
-        the "name" field of logging records generated within the
-        "sqlalchemy.engine" logger. Defaults to a hexstring of the
-        object's id.
-
-    :param max_overflow=10: the number of connections to allow in
-        connection pool "overflow", that is connections that can be
-        opened above and beyond the pool_size setting, which defaults
-        to five. this is only used with :class:`~sqlalchemy.pool.QueuePool`.
-
-    :param module=None: reference to a Python module object (the module
-        itself, not its string name).  Specifies an alternate DBAPI module to
-        be used by the engine's dialect.  Each sub-dialect references a
-        specific DBAPI which will be imported before first connect.  This
-        parameter causes the import to be bypassed, and the given module to
-        be used instead. Can be used for testing of DBAPIs as well as to
-        inject "mock" DBAPI implementations into the :class:`.Engine`.
-
-    :param pool=None: an already-constructed instance of
-        :class:`~sqlalchemy.pool.Pool`, such as a
-        :class:`~sqlalchemy.pool.QueuePool` instance. If non-None, this
-        pool will be used directly as the underlying connection pool
-        for the engine, bypassing whatever connection parameters are
-        present in the URL argument. For information on constructing
-        connection pools manually, see :ref:`pooling_toplevel`.
-
-    :param poolclass=None: a :class:`~sqlalchemy.pool.Pool`
-        subclass, which will be used to create a connection pool
-        instance using the connection parameters given in the URL. Note
-        this differs from ``pool`` in that you don't actually
-        instantiate the pool in this case, you just indicate what type
-        of pool to be used.
-
-    :param pool_logging_name:  String identifier which will be used within
-       the "name" field of logging records generated within the
-       "sqlalchemy.pool" logger. Defaults to a hexstring of the object's
-       id.
-
-    :param pool_size=5: the number of connections to keep open
-        inside the connection pool. This used with
-        :class:`~sqlalchemy.pool.QueuePool` as
-        well as :class:`~sqlalchemy.pool.SingletonThreadPool`.  With
-        :class:`~sqlalchemy.pool.QueuePool`, a ``pool_size`` setting
-        of 0 indicates no limit; to disable pooling, set ``poolclass`` to
-        :class:`~sqlalchemy.pool.NullPool` instead.
-
-    :param pool_recycle=-1: this setting causes the pool to recycle
-        connections after the given number of seconds has passed. It
-        defaults to -1, or no timeout. For example, setting to 3600
-        means connections will be recycled after one hour. Note that
-        MySQL in particular will disconnect automatically if no
-        activity is detected on a connection for eight hours (although
-        this is configurable with the MySQLDB connection itself and the
-        server configuration as well).
-
-    :param pool_reset_on_return='rollback': set the "reset on return"
-        behavior of the pool, which is whether ``rollback()``,
-        ``commit()``, or nothing is called upon connections
-        being returned to the pool.  See the docstring for
-        ``reset_on_return`` at :class:`.Pool`.
-
-        .. versionadded:: 0.7.6
-
-    :param pool_timeout=30: number of seconds to wait before giving
-        up on getting a connection from the pool. This is only used
-        with :class:`~sqlalchemy.pool.QueuePool`.
-
-    :param strategy='plain': selects alternate engine implementations.
-        Currently available are:
-
-        * the ``threadlocal`` strategy, which is described in
-          :ref:`threadlocal_strategy`;
-        * the ``mock`` strategy, which dispatches all statement
-          execution to a function passed as the argument ``executor``.

-        is suitable for usage by end-user schemes to communicate with

-
-        :param autocommit: Available on: Connection, statement.
-          When True, a COMMIT will be invoked after execution
-          when executed in 'autocommit' mode, i.e. when an explicit
-          transaction is not begun on the connection. Note that DBAPI
-          connections by default are always in a transaction - SQLAlchemy uses
-          rules applied to different kinds of statements to determine if
-          COMMIT will be invoked in order to provide its "autocommit" feature.
-          Typically, all INSERT/UPDATE/DELETE statements as well as
-          CREATE/DROP statements have autocommit behavior enabled; SELECT
-          constructs do not. Use this option when invoking a SELECT or other
-          specific SQL construct where COMMIT is desired (typically when
-          calling stored procedures and such), and an explicit
-          transaction is not in progress.
-
-        :param compiled_cache: Available on: Connection.
-          A dictionary where :class:`.Compiled` objects
-          will be cached when the :class:`.Connection` compiles a clause
-          expression into a :class:`.Compiled` object.
-          It is the user's responsibility to
-          manage the size of this dictionary, which will have keys
-          corresponding to the dialect, clause element, the column
-          names within the VALUES or SET clause of an INSERT or UPDATE,
-          as well as the "batch" mode for an INSERT or UPDATE statement.
-          The format of this dictionary is not guaranteed to stay the
-          same in future releases.
-
-          Note that the ORM makes use of its own "compiled" caches for
-          some operations, including flush operations.  The caching
-          used by the ORM internally supersedes a cache dictionary
-          specified here.
-
-        :param isolation_level: Available on: Connection.
-          Set the transaction isolation level for
-          the lifespan of this connection.   Valid values include
-          those string values accepted by the ``isolation_level``
-          parameter passed to :func:`.create_engine`, and are
-          database specific, including those for :ref:`sqlite_toplevel`,
-          :ref:`postgresql_toplevel` - see those dialect's documentation
-          for further info.
-
-          Note that this option necessarily affects the underlying
-          DBAPI connection for the lifespan of the originating
-          :class:`.Connection`, and is not per-execution. This
-          setting is not removed until the underlying DBAPI connection
-          is returned to the connection pool, i.e.
-          the :meth:`.Connection.close` method is called.
-
-        :param no_parameters: When ``True``, if the final parameter
-          list or dictionary is totally empty, will invoke the
-          statement on the cursor as ``cursor.execute(statement)``,
-          not passing the parameter collection at all.
-          Some DBAPIs such as psycopg2 and mysql-python consider
-          percent signs as significant only when parameters are
-          present; this option allows code to generate SQL
-          containing percent signs (and possibly other characters)
-          that is neutral regarding whether it's executed by the DBAPI
-          or piped into a script that's later invoked by

-        objects that contain the execution option ``shard_id=shard2``.
-

-class Dialect(object):
-    """Define the behavior of a specific database and DB-API combination.
-
-    Any aspect of metadata definition, SQL query generation,
-    execution, result-set handling, or anything else which varies
-    between databases is defined under the general category of the
-    Dialect.  The Dialect acts as a factory for other
-    database-specific object implementations including
-    ExecutionContext, Compiled, DefaultGenerator, and TypeEngine.
-
-    All Dialects implement the following attributes:
-
-    name
-      identifying name for the dialect from a DBAPI-neutral point of view
-      (i.e. 'sqlite')
-
-    driver
-      identifying name for the dialect's DBAPI
-
-    positional
-      True if the paramstyle for this Dialect is positional.
-
-    paramstyle
-      the paramstyle to be used (some DB-APIs support multiple
-      paramstyles).
-
-    convert_unicode
-      True if Unicode conversion should be applied to all ``str``
-      types.
-
-    encoding
-      type of encoding to use for unicode, usually defaults to
-      'utf-8'.
-
-    statement_compiler
-      a :class:`.Compiled` class used to compile SQL statements
-
-    ddl_compiler
-      a :class:`.Compiled` class used to compile DDL statements
-
-    server_version_info
-      a tuple containing a version number for the DB backend in use.
-      This value is only available for supporting dialects, and is
-      typically populated during the initial connection to the database.
-
-    default_schema_name
-     the name of the default schema.  This value is only available for
-     supporting dialects, and is typically populated during the
-     initial connection to the database.
-
-    execution_ctx_cls
-      a :class:`.ExecutionContext` class used to handle statement execution
-
-    execute_sequence_format
-      either the 'tuple' or 'list' type, depending on what cursor.execute()
-      accepts for the second argument (they vary).
-
-    preparer
-      a :class:`~sqlalchemy.sql.compiler.IdentifierPreparer` class used to
-      quote identifiers.
-
-    supports_alter
-      ``True`` if the database supports ``ALTER TABLE``.
-
-    max_identifier_length
-      The maximum length of identifier names.
-
-    supports_unicode_statements
-      Indicate whether the DB-API can receive SQL statements as Python
-      unicode strings
-
-    supports_unicode_binds
-      Indicate whether the DB-API can receive string bind parameters
-      as Python unicode strings
-
-    supports_sane_rowcount
-      Indicate whether the dialect properly implements rowcount for
-      ``UPDATE`` and ``DELETE`` statements.
-
-    supports_sane_multi_rowcount
-      Indicate whether the dialect properly implements rowcount for
-      ``UPDATE`` and ``DELETE`` statements when executed via
-      executemany.
-
-    preexecute_autoincrement_sequences
-      True if 'implicit' primary key functions must be executed separately
-      in order to get their value.   This is currently oriented towards
-      Postgresql.
-
-    implicit_returning
-      use RETURNING or equivalent during INSERT execution in order to load
-      newly generated primary keys and other column defaults in one execution,
-      which are then available via inserted_primary_key.
-      If an insert statement has returning() specified explicitly,
-      the "implicit" functionality is not used and inserted_primary_key
-      will not be available.
-
-    dbapi_type_map
-      A mapping of DB-API type objects present in this Dialect's
-      DB-API implementation mapped to TypeEngine implementations used
-      by the dialect.
-
-      This is used to apply types to result sets based on the DB-API
-      types present in cursor.description; it only takes effect for
-      result sets against textual statements where no explicit
-      typemap was present.
-
-    colspecs
-      A dictionary of TypeEngine classes from sqlalchemy.types mapped
-      to subclasses that are specific to the dialect class.  This
-      dictionary is class-level only and is not accessed from the
-      dialect instance itself.
-
-    supports_default_values
-      Indicates if the construct ``INSERT INTO tablename DEFAULT
-      VALUES`` is supported
-
-    supports_sequences
-      Indicates if the dialect supports CREATE SEQUENCE or similar.
-
-    sequences_optional
-      If True, indicates if the "optional" flag on the Sequence() construct
-      should signal to not generate a CREATE SEQUENCE. Applies only to
-      dialects that support sequences. Currently used only to allow Postgresql
-      SERIAL to be used on a column that specifies Sequence() for usage on
-      other backends.
-
-    supports_native_enum
-      Indicates if the dialect supports a native ENUM construct.
-      This will prevent types.Enum from generating a CHECK
-      constraint when that type is used.
-
-    supports_native_boolean
-      Indicates if the dialect supports a native boolean construct.
-      This will prevent types.Boolean from generating a CHECK
-      constraint when that type is used.

-"""Provides an abstraction for obtaining database schema information.
-
-Usage Notes:
-
-Here are some general conventions when accessing the low level inspector
-methods such as get_table_names, get_columns, etc.
-
-1. Inspector methods return lists of dicts in most cases for the following
-   reasons:
-
-   * They're both standard types that can be serialized.
-   * Using a dict instead of a tuple allows easy expansion of attributes.
-   * Using a list for the outer structure maintains order and is easy to work
-     with (e.g. list comprehension [d['name'] for d in cols]).
-
-2. Records that contain a name, such as the column name in a column record
-   use the key 'name'. So for most return values, each record will have a
-   'name' attribute..

-             as DBAPIs cannot support this functionality when rows are
-             unbuffered.
-
-           * :attr:`.ResultProxy.rowcount` may not be fully implemented by
-             all dialects.  In particular, most DBAPIs do not support an
-             aggregate rowcount result from an executemany call.

-"""Attribute implementation for _Dispatch classes.
-
-The various listener targets for a particular event class are represented
-as attributes, which refer to collections of listeners to be fired off.
-These collections can exist at the class level as well as at the instance
-level.  An event is fired off using code like this::
-
-    some_object.dispatch.first_connect(arg1, arg2)
-
-Above, ``some_object.dispatch`` would be an instance of ``_Dispatch`` and
-``first_connect`` is typically an instance of ``_ListenerCollection``
-if event listeners are present, or ``_EmptyListener`` if none are present.
-
-The attribute mechanics here spend effort trying to ensure listener functions
-are available with a minimum of function call overhead, that unnecessary
-objects aren't created (i.e. many empty per-instance listener collections),
-as well as that everything is garbage collectable when owning references are
-lost.  Other features such as "propagation" of listener functions across
-many ``_Dispatch`` instances, "joining" of multiple ``_Dispatch`` instances,
-as well as support for subclass propagation (e.g. events assigned to
-``Pool`` vs. ``QueuePool``) are all implemented here.

-    Define event listeners for schema objects,
-    that is, :class:`.SchemaItem` and other :class:`.SchemaEventTarget`
-    subclasses, including :class:`.MetaData`, :class:`.Table`,
-    :class:`.Column`.
-
-    :class:`.MetaData` and :class:`.Table` support events
-    specifically regarding when CREATE and DROP
-    DDL is emitted to the database.
-
-    Attachment events are also provided to customize
-    behavior whenever a child schema element is associated
-    with a parent, such as, when a :class:`.Column` is associated
-    with its :class:`.Table`, when a :class:`.ForeignKeyConstraint`
-    is associated with a :class:`.Table`, etc.
-
-    Example using the ``after_create`` event::
-
-        from sqlalchemy import event
-        from sqlalchemy import Table, Column, Metadata, Integer
-
-        m = MetaData()
-        some_table = Table('some_table', m, Column('data', Integer))

-
-        event.listen(some_table, "after_create", after_create)
-
-    DDL events integrate closely with the
-    :class:`.DDL` class and the :class:`.DDLElement` hierarchy
-    of DDL clause constructs, which are themselves appropriate
-    as listener callables::
-
-        from sqlalchemy import DDL

-            some_table,

-        )

-    functions.

-
-    The returned value is an instance of :class:`.AssociationProxy`.
-
-    Implements a Python property representing a relationship as a collection
-    of simpler values, or a scalar value.  The proxied property will mimic
-    the collection type of the target (list, dict or set), or, in the case of
-    a one to one relationship, a simple scalar value.
-
-    :param target_collection: Name of the attribute we'll proxy to.
-      This attribute is typically mapped by
-      :func:`~sqlalchemy.orm.relationship` to link to a target collection, but
-      can also be a many-to-one or non-scalar relationship.
-
-    :param attr: Attribute on the associated instance or instances we'll
-      proxy for.
-

-      passed: key and value.
-
-      If you want to construct instances differently, supply a *creator*
-      function that takes arguments as above and returns instances.
-
-      For scalar relationships, creator() will be called if the target is None.
-      If the target is present, set operations are proxied to setattr() on the
-      associated object.
-
-      If you have an associated object with multiple attributes, you may set
-      up multiple association proxies mapping to different attributes.  See

-"""Define an extension to the :mod:`sqlalchemy.ext.declarative` system
-which automatically generates mapped classes and relationships from a database
-schema, typically though not necessarily one which is reflected.
-
-.. versionadded:: 0.9.1 Added :mod:`sqlalchemy.ext.automap`.
-
-.. note::
-
-    The :mod:`sqlalchemy.ext.automap` extension should be considered
-    **experimental** as of 0.9.1.   Featureset and API stability is
-    not guaranteed at this time.
-
-It is hoped that the :class:`.AutomapBase` system provides a quick
-and modernized solution to the problem that the very famous
-`SQLSoup <https://sqlsoup.readthedocs.org/en/latest/>`_
-also tries to solve, that of generating a quick and rudimentary object
-model from an existing database on the fly.  By addressing the issue strictly
-at the mapper configuration level, and integrating fully with existing
-Declarative class techniques, :class:`.AutomapBase` seeks to provide
-a well-integrated approach to the issue of expediently auto-generating ad-hoc
-mappings.
-
-
-Basic Use
-=========
-
-The simplest usage is to reflect an existing database into a new model.
-We create a new :class:`.AutomapBase` class in a similar manner as to how
-we create a declarative base class, using :func:`.automap_base`.
-We then call :meth:`.AutomapBase.prepare` on the resulting base class,
-asking it to reflect the schema and produce mappings::
-
-    from sqlalchemy.ext.automap import automap_base
-    from sqlalchemy.orm import Session
-    from sqlalchemy import create_engine
-
-    Base = automap_base()
-
-    # engine, suppose it has two tables 'user' and 'address' set up
-    engine = create_engine("sqlite:///mydatabase.db")
-
-    # reflect the tables
-    Base.prepare(engine, reflect=True)
-
-    # mapped classes are now created with names by default
-    # matching that of the table name.
-    User = Base.classes.user
-    Address = Base.classes.address
-
-    session = Session(engine)
-
-    # rudimentary relationships are produced
-    session.add(Address(email_address="foo@bar.com", user=User(name="foo")))
-    session.commit()
-
-    # collection-based relationships are by default named "<classname>_collection"
-    print (u1.address_collection)
-
-Above, calling :meth:`.AutomapBase.prepare` while passing along the
-:paramref:`.AutomapBase.prepare.reflect` parameter indicates that the
-:meth:`.MetaData.reflect` method will be called on this declarative base
-classes' :class:`.MetaData` collection; then, each viable
-:class:`.Table` within the :class:`.MetaData` will get a new mapped class
-generated automatically.  The :class:`.ForeignKeyConstraint` objects which
-link the various tables together will be used to produce new, bidirectional
-:func:`.relationship` objects between classes.   The classes and relationships
-follow along a default naming scheme that we can customize.  At this point,
-our basic mapping consisting of related ``User`` and ``Address`` classes is ready
-to use in the traditional way.
-
-Generating Mappings from an Existing MetaData
-=============================================
-
-We can pass a pre-declared :class:`.MetaData` object to :func:`.automap_base`.
-This object can be constructed in any way, including programmatically, from
-a serialized file, or from itself being reflected using :meth:`.MetaData.reflect`.
-Below we illustrate a combination of reflection and explicit table declaration::
-
-    from sqlalchemy import create_engine, MetaData, Table, Column, ForeignKey
-    engine = create_engine("sqlite:///mydatabase.db")
-
-    # produce our own MetaData object
-    metadata = MetaData()
-
-    # we can reflect it ourselves from a database, using options
-    # such as 'only' to limit what tables we look at...
-    metadata.reflect(engine, only=['user', 'address'])
-
-    # ... or just define our own Table objects with it (or combine both)
-    Table('user_order', metadata,
-                    Column('id', Integer, primary_key=True),
-                    Column('user_id', ForeignKey('user.id'))
-                )
-
-    # we can then produce a set of mappings from this MetaData.
-    Base = automap_base(metadata=metadata)
-
-    # calling prepare() just sets up mapped classes and relationships.
-    Base.prepare()
-
-    # mapped classes are ready
-    User, Address, Order = Base.classes.user, Base.classes.address, Base.classes.user_order
-
-Specifying Classes Explcitly
-============================
-
-The :mod:`.sqlalchemy.ext.automap` extension allows classes to be defined
-explicitly, in a way similar to that of the :class:`.DeferredReflection` class.
-Classes that extend from :class:`.AutomapBase` act like regular declarative
-classes, but are not immediately mapped after their construction, and are instead
-mapped when we call :meth:`.AutomapBase.prepare`.  The :meth:`.AutomapBase.prepare`
-method will make use of the classes we've established based on the table name
-we use.  If our schema contains tables ``user`` and ``address``, we can define
-one or both of the classes to be used::
-
-    from sqlalchemy.ext.automap import automap_base
-    from sqlalchemy import create_engine
-
-    # automap base
-    Base = automap_base()
-
-    # pre-declare User for the 'user' table
-    class User(Base):
-        __tablename__ = 'user'
-
-        # override schema elements like Columns
-        user_name = Column('name', String)
-
-        # override relationships too, if desired.
-        # we must use the same name that automap would use for the relationship,
-        # and also must refer to the class name that automap will generate
-        # for "address"
-        address_collection = relationship("address", collection_class=set)
-
-    # reflect
-    engine = create_engine("sqlite:///mydatabase.db")
-    Base.prepare(engine, reflect=True)
-
-    # we still have Address generated from the tablename "address",
-    # but User is the same as Base.classes.User now
-
-    Address = Base.classes.address
-
-    u1 = session.query(User).first()
-    print (u1.address_collection)
-
-    # the backref is still there:
-    a1 = session.query(Address).first()
-    print (a1.user)
-
-Above, one of the more intricate details is that we illustrated overriding
-one of the :func:`.relationship` objects that automap would have created.
-To do this, we needed to make sure the names match up with what automap
-would normally generate, in that the relationship name would be ``User.address_collection``
-and the name of the class referred to, from automap's perspective, is called
-``address``, even though we are referring to it as ``Address`` within our usage
-of this class.
-
-Overriding Naming Schemes
-=========================
-
-:mod:`.sqlalchemy.ext.automap` is tasked with producing mapped classes and
-relationship names based on a schema, which means it has decision points in how
-these names are determined.  These three decision points are provided using
-functions which can be passed to the :meth:`.AutomapBase.prepare` method, and
-are known as :func:`.classname_for_table`,
-:func:`.name_for_scalar_relationship`,
-and :func:`.name_for_collection_relationship`.  Any or all of these
-functions are provided as in the example below, where we use a "camel case"
-scheme for class names and a "pluralizer" for collection names using the
-`Inflect <https://pypi.python.org/pypi/inflect>`_ package::
-
-    import re
-    import inflect
-
-    def camelize_classname(base, tablename, table):
-        "Produce a 'camelized' class name, e.g. "
-        "'words_and_underscores' -> 'WordsAndUnderscores'"
-
-        return str(tablename[0].upper() + \\
-                re.sub(r'_(\w)', lambda m: m.group(1).upper(), tablename[1:]))
-
-    _pluralizer = inflect.engine()
-    def pluralize_collection(base, local_cls, referred_cls, constraint):
-        "Produce an 'uncamelized', 'pluralized' class name, e.g. "
-        "'SomeTerm' -> 'some_terms'"
-
-        referred_name = referred_cls.__name__
-        uncamelized = referred_name[0].lower() + \\
-                        re.sub(r'\W',
-                                lambda m: "_%s" % m.group(0).lower(),
-                                referred_name[1:])
-        pluralized = _pluralizer.plural(uncamelized)
-        return pluralized
-
-    from sqlalchemy.ext.automap import automap_base
-
-    Base = automap_base()
-
-    engine = create_engine("sqlite:///mydatabase.db")
-
-    Base.prepare(engine, reflect=True,
-                classname_for_table=camelize_classname,
-                name_for_collection_relationship=pluralize_collection
-        )
-
-From the above mapping, we would now have classes ``User`` and ``Address``,
-where the collection from ``User`` to ``Address`` is called ``User.addresses``::
-
-    User, Address = Base.classes.User, Base.classes.Address
-
-    u1 = User(addresses=[Address(email="foo@bar.com")])
-
-Relationship Detection
-======================
-
-The vast majority of what automap accomplishes is the generation of
-:func:`.relationship` structures based on foreign keys.  The mechanism
-by which this works for many-to-one and one-to-many relationships is as follows:
-
-1. A given :class:`.Table`, known to be mapped to a particular class,
-   is examined for :class:`.ForeignKeyConstraint` objects.
-
-2. From each :class:`.ForeignKeyConstraint`, the remote :class:`.Table`
-   object present is matched up to the class to which it is to be mapped,
-   if any, else it is skipped.
-
-3. As the :class:`.ForeignKeyConstraint` we are examining correponds to a reference
-   from the immediate mapped class,
-   the relationship will be set up as a many-to-one referring to the referred class;
-   a corresponding one-to-many backref will be created on the referred class referring
-   to this class.
-
-4. The names of the relationships are determined using the
-   :paramref:`.AutomapBase.prepare.name_for_scalar_relationship` and
-   :paramref:`.AutomapBase.prepare.name_for_collection_relationship`
-   callable functions.  It is important to note that the default relationship
-   naming derives the name from the **the actual class name**.  If you've
-   given a particular class an explicit name by declaring it, or specified an
-   alternate class naming scheme, that's the name from which the relationship
-   name will be derived.
-
-5. The classes are inspected for an existing mapped property matching these
-   names.  If one is detected on one side, but none on the other side, :class:`.AutomapBase`
-   attempts to create a relationship on the missing side, then uses the
-   :paramref:`.relationship.back_populates` parameter in order to point
-   the new relationship to the other side.
-
-6. In the usual case where no relationship is on either side,
-   :meth:`.AutomapBase.prepare` produces a :func:`.relationship` on the "many-to-one"
-   side and matches it to the other using the :paramref:`.relationship.backref`
-   parameter.
-
-7. Production of the :func:`.relationship` and optionally the :func:`.backref`
-   is handed off to the :paramref:`.AutomapBase.prepare.generate_relationship`
-   function, which can be supplied by the end-user in order to augment
-   the arguments passed to :func:`.relationship` or :func:`.backref` or to
-   make use of custom implementations of these functions.
-
-Custom Relationship Arguments
------------------------------
-
-The :paramref:`.AutomapBase.prepare.generate_relationship` hook can be used
-to add parameters to relationships.  For most cases, we can make use of the
-existing :func:`.automap.generate_relationship` function to return
-the object, after augmenting the given keyword dictionary with our own
-arguments.
-
-Below is an illustration of how to send
-:paramref:`.relationship.cascade` and
-:paramref:`.relationship.passive_deletes`
-options along to all one-to-many relationships::
-
-    from sqlalchemy.ext.automap import generate_relationship
-
-    def _gen_relationship(base, direction, return_fn,
-                                    attrname, local_cls, referred_cls, **kw):
-        if direction is interfaces.ONETOMANY:
-            kw['cascade'] = 'all, delete-orphan'
-            kw['passive_deletes'] = True
-        # make use of the built-in function to actually return
-        # the result.
-        return generate_relationship(base, direction, return_fn,
-                                        attrname, local_cls, referred_cls, **kw)
-
-    from sqlalchemy.ext.automap import automap_base
-    from sqlalchemy import create_engine
-
-    # automap base
-    Base = automap_base()
-
-    engine = create_engine("sqlite:///mydatabase.db")
-    Base.prepare(engine, reflect=True,
-                generate_relationship=_gen_relationship)
-
-Many-to-Many relationships
---------------------------
-
-:mod:`.sqlalchemy.ext.automap` will generate many-to-many relationships, e.g.
-those which contain a ``secondary`` argument.  The process for producing these
-is as follows:
-
-1. A given :class:`.Table` is examined for :class:`.ForeignKeyConstraint` objects,
-   before any mapped class has been assigned to it.
-
-2. If the table contains two and exactly two :class:`.ForeignKeyConstraint`
-   objects, and all columns within this table are members of these two
-   :class:`.ForeignKeyConstraint` objects, the table is assumed to be a
-   "secondary" table, and will **not be mapped directly**.
-
-3. The two (or one, for self-referential) external tables to which the :class:`.Table`
-   refers to are matched to the classes to which they will be mapped, if any.
-
-4. If mapped classes for both sides are located, a many-to-many bi-directional
-   :func:`.relationship` / :func:`.backref` pair is created between the two
-   classes.
-
-5. The override logic for many-to-many works the same as that of one-to-many/
-   many-to-one; the :func:`.generate_relationship` function is called upon
-   to generate the strucures and existing attributes will be maintained.
-
-Relationships with Inheritance
-------------------------------
-
-:mod:`.sqlalchemy.ext.automap` will not generate any relationships between
-two classes that are in an inheritance relationship.   That is, with two classes
-given as follows::
-
-    class Employee(Base):
-        __tablename__ = 'employee'
-        id = Column(Integer, primary_key=True)
-        type = Column(String(50))
-        __mapper_args__ = {
-             'polymorphic_identity':'employee', 'polymorphic_on': type
-        }
-
-    class Engineer(Employee):
-        __tablename__ = 'engineer'
-        id = Column(Integer, ForeignKey('employee.id'), primary_key=True)
-        __mapper_args__ = {
-            'polymorphic_identity':'engineer',
-        }
-
-The foreign key from ``Engineer`` to ``Employee`` is used not for a relationship,
-but to establish joined inheritance between the two classes.
-
-Note that this means automap will not generate *any* relationships
-for foreign keys that link from a subclass to a superclass.  If a mapping
-has actual relationships from subclass to superclass as well, those
-need to be explicit.  Below, as we have two separate foreign keys
-from ``Engineer`` to ``Employee``, we need to set up both the relationship
-we want as well as the ``inherit_condition``, as these are not things
-SQLAlchemy can guess::
-
-    class Employee(Base):
-        __tablename__ = 'employee'
-        id = Column(Integer, primary_key=True)
-        type = Column(String(50))
-
-        __mapper_args__ = {
-            'polymorphic_identity':'employee', 'polymorphic_on':type
-        }
-
-    class Engineer(Employee):
-        __tablename__ = 'engineer'
-        id = Column(Integer, ForeignKey('employee.id'), primary_key=True)
-        favorite_employee_id = Column(Integer, ForeignKey('employee.id'))
-
-        favorite_employee = relationship(Employee, foreign_keys=favorite_employee_id)
-
-        __mapper_args__ = {
-            'polymorphic_identity':'engineer',
-            'inherit_condition': id == Employee.id
-        }
-
-
-Using Automap with Explicit Declarations
-========================================
-
-As noted previously, automap has no dependency on reflection, and can make
-use of any collection of :class:`.Table` objects within a :class:`.MetaData`
-collection.  From this, it follows that automap can also be used
-generate missing relationships given an otherwise complete model that fully defines
-table metadata::
-
-    from sqlalchemy.ext.automap import automap_base
-    from sqlalchemy import Column, Integer, String, ForeignKey
-
-    Base = automap_base()
-
-    class User(Base):
-        __tablename__ = 'user'
-
-        id = Column(Integer, primary_key=True)
-        name = Column(String)
-
-    class Address(Base):
-        __tablename__ = 'address'
-
-        id = Column(Integer, primary_key=True)
-        email = Column(String)
-        user_id = Column(ForeignKey('user.id'))
-
-    # produce relationships
-    Base.prepare()
-
-    # mapping is complete, with "address_collection" and
-    # "user" relationships
-    a1 = Address(email='u1')
-    a2 = Address(email='u2')
-    u1 = User(address_collection=[a1, a2])
-    assert a1.user is u1
-
-Above, given mostly complete ``User`` and ``Address`` mappings, the
-:class:`.ForeignKey` which we defined on ``Address.user_id`` allowed a
-bidirectional relationship pair ``Address.user`` and ``User.address_collection``
-to be generated on the mapped classes.
-
-Note that when subclassing :class:`.AutomapBase`, the :meth:`.AutomapBase.prepare`
-method is required; if not called, the classes we've declared are in an
-un-mapped state.

-"""Provides an API for creation of custom ClauseElements and compilers.
-
-Synopsis
-========
-
-Usage involves the creation of one or more
-:class:`~sqlalchemy.sql.expression.ClauseElement` subclasses and one or
-more callables defining its compilation::
-
-    from sqlalchemy.ext.compiler import compiles
-    from sqlalchemy.sql.expression import ColumnClause
-
-    class MyColumn(ColumnClause):
-        pass
-
-    @compiles(MyColumn)
-    def compile_mycolumn(element, compiler, **kw):
-        return "[%s]" % element.name
-
-Above, ``MyColumn`` extends :class:`~sqlalchemy.sql.expression.ColumnClause`,
-the base expression element for named column objects. The ``compiles``
-decorator registers itself with the ``MyColumn`` class so that it is invoked
-when the object is compiled to a string::
-
-    from sqlalchemy import select
-
-    s = select([MyColumn('x'), MyColumn('y')])
-    print str(s)
-
-Produces::
-
-    SELECT [x], [y]
-
-Dialect-specific compilation rules
-==================================
-
-Compilers can also be made dialect-specific. The appropriate compiler will be
-invoked for the dialect in use::
-
-    from sqlalchemy.schema import DDLElement
-
-    class AlterColumn(DDLElement):
-
-        def __init__(self, column, cmd):
-            self.column = column
-            self.cmd = cmd
-
-    @compiles(AlterColumn)
-    def visit_alter_column(element, compiler, **kw):
-        return "ALTER COLUMN %s ..." % element.column.name
-
-    @compiles(AlterColumn, 'postgresql')
-    def visit_alter_column(element, compiler, **kw):
-        return "ALTER TABLE %s ALTER COLUMN %s ..." % (element.table.name, element.column.name)
-
-The second ``visit_alter_table`` will be invoked when any ``postgresql``
-dialect is used.
-
-Compiling sub-elements of a custom expression construct
-=======================================================
-
-The ``compiler`` argument is the
-:class:`~sqlalchemy.engine.interfaces.Compiled` object in use. This object
-can be inspected for any information about the in-progress compilation,
-including ``compiler.dialect``, ``compiler.statement`` etc. The
-:class:`~sqlalchemy.sql.compiler.SQLCompiler` and
-:class:`~sqlalchemy.sql.compiler.DDLCompiler` both include a ``process()``
-method which can be used for compilation of embedded attributes::
-
-    from sqlalchemy.sql.expression import Executable, ClauseElement
-
-    class InsertFromSelect(Executable, ClauseElement):
-        def __init__(self, table, select):
-            self.table = table
-            self.select = select
-
-    @compiles(InsertFromSelect)
-    def visit_insert_from_select(element, compiler, **kw):
-        return "INSERT INTO %s (%s)" % (
-            compiler.process(element.table, asfrom=True),
-            compiler.process(element.select)
-        )
-
-    insert = InsertFromSelect(t1, select([t1]).where(t1.c.x>5))
-    print insert
-
-Produces::
-
-    "INSERT INTO mytable (SELECT mytable.x, mytable.y, mytable.z FROM mytable WHERE mytable.x > :x_1)"
-
-.. note::
-
-    The above ``InsertFromSelect`` construct is only an example, this actual
-    functionality is already available using the
-    :meth:`.Insert.from_select` method.
-
-.. note::
-
-   The above ``InsertFromSelect`` construct probably wants to have "autocommit"
-   enabled.  See :ref:`enabling_compiled_autocommit` for this step.
-
-Cross Compiling between SQL and DDL compilers
----------------------------------------------
-
-SQL and DDL constructs are each compiled using different base compilers -
-``SQLCompiler`` and ``DDLCompiler``.   A common need is to access the
-compilation rules of SQL expressions from within a DDL expression. The
-``DDLCompiler`` includes an accessor ``sql_compiler`` for this reason, such as
-below where we generate a CHECK constraint that embeds a SQL expression::
-
-    @compiles(MyConstraint)
-    def compile_my_constraint(constraint, ddlcompiler, **kw):
-        return "CONSTRAINT %s CHECK (%s)" % (
-            constraint.name,
-            ddlcompiler.sql_compiler.process(constraint.expression)
-        )
-
-.. _enabling_compiled_autocommit:
-
-Enabling Autocommit on a Construct
-==================================
-
-Recall from the section :ref:`autocommit` that the :class:`.Engine`, when
-asked to execute a construct in the absence of a user-defined transaction,
-detects if the given construct represents DML or DDL, that is, a data
-modification or data definition statement, which requires (or may require,
-in the case of DDL) that the transaction generated by the DBAPI be committed
-(recall that DBAPI always has a transaction going on regardless of what
-SQLAlchemy does).   Checking for this is actually accomplished by checking for
-the "autocommit" execution option on the construct.    When building a
-construct like an INSERT derivation, a new DDL type, or perhaps a stored
-procedure that alters data, the "autocommit" option needs to be set in order
-for the statement to function with "connectionless" execution
-(as described in :ref:`dbengine_implicit`).
-
-Currently a quick way to do this is to subclass :class:`.Executable`, then
-add the "autocommit" flag to the ``_execution_options`` dictionary (note this
-is a "frozen" dictionary which supplies a generative ``union()`` method)::
-
-    from sqlalchemy.sql.expression import Executable, ClauseElement
-
-    class MyInsertThing(Executable, ClauseElement):
-        _execution_options = \\
-            Executable._execution_options.union({'autocommit': True})
-
-More succinctly, if the construct is truly similar to an INSERT, UPDATE, or
-DELETE, :class:`.UpdateBase` can be used, which already is a subclass
-of :class:`.Executable`, :class:`.ClauseElement` and includes the
-``autocommit`` flag::
-
-    from sqlalchemy.sql.expression import UpdateBase
-
-    class MyInsertThing(UpdateBase):
-        def __init__(self, ...):
-            ...
-
-
-
-
-DDL elements that subclass :class:`.DDLElement` already have the
-"autocommit" flag turned on.
-
-
-
-
-Changing the default compilation of existing constructs
-=======================================================
-
-The compiler extension applies just as well to the existing constructs.  When
-overriding the compilation of a built in SQL construct, the @compiles
-decorator is invoked upon the appropriate class (be sure to use the class,
-i.e. ``Insert`` or ``Select``, instead of the creation function such
-as ``insert()`` or ``select()``).
-
-Within the new compilation function, to get at the "original" compilation
-routine, use the appropriate visit_XXX method - this
-because compiler.process() will call upon the overriding routine and cause
-an endless loop.   Such as, to add "prefix" to all insert statements::
-
-    from sqlalchemy.sql.expression import Insert
-
-    @compiles(Insert)
-    def prefix_inserts(insert, compiler, **kw):
-        return compiler.visit_insert(insert.prefix_with("some prefix"), **kw)
-
-The above compiler will prefix all INSERT statements with "some prefix" when
-compiled.
-
-.. _type_compilation_extension:
-
-Changing Compilation of Types
-=============================
-
-``compiler`` works for types, too, such as below where we implement the
-MS-SQL specific 'max' keyword for ``String``/``VARCHAR``::
-
-    @compiles(String, 'mssql')
-    @compiles(VARCHAR, 'mssql')
-    def compile_varchar(element, compiler, **kw):
-        if element.length == 'max':
-            return "VARCHAR('max')"
-        else:
-            return compiler.visit_VARCHAR(element, **kw)
-
-    foo = Table('foo', metadata,
-        Column('data', VARCHAR('max'))
-    )
-
-Subclassing Guidelines
-======================
-
-A big part of using the compiler extension is subclassing SQLAlchemy
-expression constructs. To make this easier, the expression and
-schema packages feature a set of "bases" intended for common tasks.
-A synopsis is as follows:
-
-* :class:`~sqlalchemy.sql.expression.ClauseElement` - This is the root
-  expression class. Any SQL expression can be derived from this base, and is
-  probably the best choice for longer constructs such as specialized INSERT
-  statements.
-
-* :class:`~sqlalchemy.sql.expression.ColumnElement` - The root of all
-  "column-like" elements. Anything that you'd place in the "columns" clause of
-  a SELECT statement (as well as order by and group by) can derive from this -
-  the object will automatically have Python "comparison" behavior.
-
-  :class:`~sqlalchemy.sql.expression.ColumnElement` classes want to have a
-  ``type`` member which is expression's return type.  This can be established
-  at the instance level in the constructor, or at the class level if its
-  generally constant::
-
-      class timestamp(ColumnElement):
-          type = TIMESTAMP()
-
-* :class:`~sqlalchemy.sql.functions.FunctionElement` - This is a hybrid of a
-  ``ColumnElement`` and a "from clause" like object, and represents a SQL
-  function or stored procedure type of call. Since most databases support
-  statements along the line of "SELECT FROM <some function>"
-  ``FunctionElement`` adds in the ability to be used in the FROM clause of a
-  ``select()`` construct::
-
-      from sqlalchemy.sql.expression import FunctionElement
-
-      class coalesce(FunctionElement):
-          name = 'coalesce'
-
-      @compiles(coalesce)
-      def compile(element, compiler, **kw):
-          return "coalesce(%s)" % compiler.process(element.clauses)
-
-      @compiles(coalesce, 'oracle')
-      def compile(element, compiler, **kw):
-          if len(element.clauses) > 2:
-              raise TypeError("coalesce only supports two arguments on Oracle")
-          return "nvl(%s)" % compiler.process(element.clauses)
-
-* :class:`~sqlalchemy.schema.DDLElement` - The root of all DDL expressions,
-  like CREATE TABLE, ALTER TABLE, etc. Compilation of ``DDLElement``
-  subclasses is issued by a ``DDLCompiler`` instead of a ``SQLCompiler``.
-  ``DDLElement`` also features ``Table`` and ``MetaData`` event hooks via the
-  ``execute_at()`` method, allowing the construct to be invoked during CREATE
-  TABLE and DROP TABLE sequences.
-
-* :class:`~sqlalchemy.sql.expression.Executable` - This is a mixin which
-  should be used with any expression class that represents a "standalone"
-  SQL statement that can be passed directly to an ``execute()`` method.  It
-  is already implicit within ``DDLElement`` and ``FunctionElement``.
-
-Further Examples
-================
-
-"UTC timestamp" function
--------------------------
-
-A function that works like "CURRENT_TIMESTAMP" except applies the
-appropriate conversions so that the time is in UTC time.   Timestamps are best
-stored in relational databases as UTC, without time zones.   UTC so that your
-database doesn't think time has gone backwards in the hour when daylight
-savings ends, without timezones because timezones are like character
-encodings - they're best applied only at the endpoints of an application
-(i.e. convert to UTC upon user input, re-apply desired timezone upon display).
-
-For Postgresql and Microsoft SQL Server::
-
-    from sqlalchemy.sql import expression
-    from sqlalchemy.ext.compiler import compiles
-    from sqlalchemy.types import DateTime
-
-    class utcnow(expression.FunctionElement):
-        type = DateTime()
-
-    @compiles(utcnow, 'postgresql')
-    def pg_utcnow(element, compiler, **kw):
-        return "TIMEZONE('utc', CURRENT_TIMESTAMP)"
-
-    @compiles(utcnow, 'mssql')
-    def ms_utcnow(element, compiler, **kw):
-        return "GETUTCDATE()"
-
-Example usage::
-
-    from sqlalchemy import (
-                Table, Column, Integer, String, DateTime, MetaData
-            )
-    metadata = MetaData()
-    event = Table("event", metadata,
-        Column("id", Integer, primary_key=True),
-        Column("description", String(50), nullable=False),
-        Column("timestamp", DateTime, server_default=utcnow())
-    )
-
-"GREATEST" function
--------------------
-
-The "GREATEST" function is given any number of arguments and returns the one
-that is of the highest value - it's equivalent to Python's ``max``
-function.  A SQL standard version versus a CASE based version which only
-accommodates two arguments::
-
-    from sqlalchemy.sql import expression
-    from sqlalchemy.ext.compiler import compiles
-    from sqlalchemy.types import Numeric
-
-    class greatest(expression.FunctionElement):
-        type = Numeric()
-        name = 'greatest'

-Synopsis
-========
-
-SQLAlchemy object-relational configuration involves the
-combination of :class:`.Table`, :func:`.mapper`, and class
-objects to define a mapped class.
-:mod:`~sqlalchemy.ext.declarative` allows all three to be
-expressed at once within the class declaration. As much as
-possible, regular SQLAlchemy schema and ORM constructs are
-used directly, so that configuration between "classical" ORM
-usage and declarative remain highly similar.
-
-As a simple example::
-
-    from sqlalchemy.ext.declarative import declarative_base
-
-    Base = declarative_base()
-
-    class SomeClass(Base):
-        __tablename__ = 'some_table'
-        id = Column(Integer, primary_key=True)
-        name =  Column(String(50))
-
-Above, the :func:`declarative_base` callable returns a new base class from
-which all mapped classes should inherit. When the class definition is
-completed, a new :class:`.Table` and :func:`.mapper` will have been generated.
-
-The resulting table and mapper are accessible via
-``__table__`` and ``__mapper__`` attributes on the
-``SomeClass`` class::
-
-    # access the mapped Table
-    SomeClass.__table__
-
-    # access the Mapper
-    SomeClass.__mapper__
-
-Defining Attributes
-===================
-
-In the previous example, the :class:`.Column` objects are
-automatically named with the name of the attribute to which they are
-assigned.
-
-To name columns explicitly with a name distinct from their mapped attribute,
-just give the column a name.  Below, column "some_table_id" is mapped to the
-"id" attribute of `SomeClass`, but in SQL will be represented as
-"some_table_id"::
-
-    class SomeClass(Base):
-        __tablename__ = 'some_table'
-        id = Column("some_table_id", Integer, primary_key=True)
-
-Attributes may be added to the class after its construction, and they will be
-added to the underlying :class:`.Table` and
-:func:`.mapper` definitions as appropriate::
-
-    SomeClass.data = Column('data', Unicode)
-    SomeClass.related = relationship(RelatedInfo)
-
-Classes which are constructed using declarative can interact freely
-with classes that are mapped explicitly with :func:`.mapper`.
-
-It is recommended, though not required, that all tables
-share the same underlying :class:`~sqlalchemy.schema.MetaData` object,
-so that string-configured :class:`~sqlalchemy.schema.ForeignKey`
-references can be resolved without issue.
-
-Accessing the MetaData
-=======================
-
-The :func:`declarative_base` base class contains a
-:class:`.MetaData` object where newly defined
-:class:`.Table` objects are collected. This object is
-intended to be accessed directly for
-:class:`.MetaData`-specific operations. Such as, to issue
-CREATE statements for all tables::
-
-    engine = create_engine('sqlite://')
-    Base.metadata.create_all(engine)
-
-:func:`declarative_base` can also receive a pre-existing
-:class:`.MetaData` object, which allows a
-declarative setup to be associated with an already
-existing traditional collection of :class:`~sqlalchemy.schema.Table`
-objects::
-
-    mymetadata = MetaData()
-    Base = declarative_base(metadata=mymetadata)
-
-
-.. _declarative_configuring_relationships:
-
-Configuring Relationships
-=========================
-
-Relationships to other classes are done in the usual way, with the added
-feature that the class specified to :func:`~sqlalchemy.orm.relationship`
-may be a string name.  The "class registry" associated with ``Base``
-is used at mapper compilation time to resolve the name into the actual
-class object, which is expected to have been defined once the mapper
-configuration is used::
-
-    class User(Base):
-        __tablename__ = 'users'
-
-        id = Column(Integer, primary_key=True)
-        name = Column(String(50))
-        addresses = relationship("Address", backref="user")
-
-    class Address(Base):
-        __tablename__ = 'addresses'
-
-        id = Column(Integer, primary_key=True)
-        email = Column(String(50))
-        user_id = Column(Integer, ForeignKey('users.id'))
-
-Column constructs, since they are just that, are immediately usable,
-as below where we define a primary join condition on the ``Address``
-class using them::
-
-    class Address(Base):
-        __tablename__ = 'addresses'
-
-        id = Column(Integer, primary_key=True)
-        email = Column(String(50))
-        user_id = Column(Integer, ForeignKey('users.id'))
-        user = relationship(User, primaryjoin=user_id == User.id)
-
-In addition to the main argument for :func:`~sqlalchemy.orm.relationship`,
-other arguments which depend upon the columns present on an as-yet
-undefined class may also be specified as strings.  These strings are
-evaluated as Python expressions.  The full namespace available within
-this evaluation includes all classes mapped for this declarative base,
-as well as the contents of the ``sqlalchemy`` package, including
-expression functions like :func:`~sqlalchemy.sql.expression.desc` and
-:attr:`~sqlalchemy.sql.expression.func`::
-
-    class User(Base):
-        # ....
-        addresses = relationship("Address",
-                             order_by="desc(Address.email)",
-                             primaryjoin="Address.user_id==User.id")
-
-For the case where more than one module contains a class of the same name,
-string class names can also be specified as module-qualified paths
-within any of these string expressions::
-
-    class User(Base):
-        # ....
-        addresses = relationship("myapp.model.address.Address",
-                             order_by="desc(myapp.model.address.Address.email)",
-                             primaryjoin="myapp.model.address.Address.user_id=="
-                                            "myapp.model.user.User.id")
-
-The qualified path can be any partial path that removes ambiguity between
-the names.  For example, to disambiguate between
-``myapp.model.address.Address`` and ``myapp.model.lookup.Address``,
-we can specify ``address.Address`` or ``lookup.Address``::
-
-    class User(Base):
-        # ....
-        addresses = relationship("address.Address",
-                             order_by="desc(address.Address.email)",
-                             primaryjoin="address.Address.user_id=="
-                                            "User.id")
-
-.. versionadded:: 0.8
-   module-qualified paths can be used when specifying string arguments
-   with Declarative, in order to specify specific modules.
-
-Two alternatives also exist to using string-based attributes.  A lambda
-can also be used, which will be evaluated after all mappers have been
-configured::
-
-    class User(Base):
-        # ...
-        addresses = relationship(lambda: Address,
-                             order_by=lambda: desc(Address.email),
-                             primaryjoin=lambda: Address.user_id==User.id)
-
-Or, the relationship can be added to the class explicitly after the classes
-are available::
-
-    User.addresses = relationship(Address,
-                              primaryjoin=Address.user_id==User.id)
-
-
-
-.. _declarative_many_to_many:
-
-Configuring Many-to-Many Relationships
-======================================
-
-Many-to-many relationships are also declared in the same way
-with declarative as with traditional mappings. The
-``secondary`` argument to
-:func:`.relationship` is as usual passed a
-:class:`.Table` object, which is typically declared in the
-traditional way.  The :class:`.Table` usually shares
-the :class:`.MetaData` object used by the declarative base::
-
-    keywords = Table(
-        'keywords', Base.metadata,
-        Column('author_id', Integer, ForeignKey('authors.id')),
-        Column('keyword_id', Integer, ForeignKey('keywords.id'))
-        )
-
-    class Author(Base):
-        __tablename__ = 'authors'
-        id = Column(Integer, primary_key=True)
-        keywords = relationship("Keyword", secondary=keywords)
-
-Like other :func:`~sqlalchemy.orm.relationship` arguments, a string is accepted
-as well, passing the string name of the table as defined in the
-``Base.metadata.tables`` collection::
-
-    class Author(Base):
-        __tablename__ = 'authors'
-        id = Column(Integer, primary_key=True)
-        keywords = relationship("Keyword", secondary="keywords")
-
-As with traditional mapping, its generally not a good idea to use
-a :class:`.Table` as the "secondary" argument which is also mapped to
-a class, unless the :func:`.relationship` is declared with ``viewonly=True``.
-Otherwise, the unit-of-work system may attempt duplicate INSERT and
-DELETE statements against the underlying table.
-
-.. _declarative_sql_expressions:
-
-Defining SQL Expressions
-========================
-
-See :ref:`mapper_sql_expressions` for examples on declaratively
-mapping attributes to SQL expressions.
-
-.. _declarative_table_args:
-
-Table Configuration
-===================
-
-Table arguments other than the name, metadata, and mapped Column
-arguments are specified using the ``__table_args__`` class attribute.
-This attribute accommodates both positional as well as keyword
-arguments that are normally sent to the
-:class:`~sqlalchemy.schema.Table` constructor.
-The attribute can be specified in one of two forms. One is as a
-dictionary::
-
-    class MyClass(Base):
-        __tablename__ = 'sometable'
-        __table_args__ = {'mysql_engine':'InnoDB'}
-
-The other, a tuple, where each argument is positional
-(usually constraints)::
-
-    class MyClass(Base):
-        __tablename__ = 'sometable'
-        __table_args__ = (
-                ForeignKeyConstraint(['id'], ['remote_table.id']),
-                UniqueConstraint('foo'),
-                )
-
-Keyword arguments can be specified with the above form by
-specifying the last argument as a dictionary::
-
-    class MyClass(Base):
-        __tablename__ = 'sometable'
-        __table_args__ = (
-                ForeignKeyConstraint(['id'], ['remote_table.id']),
-                UniqueConstraint('foo'),
-                {'autoload':True}
-                )
-
-Using a Hybrid Approach with __table__
-=======================================
-
-As an alternative to ``__tablename__``, a direct
-:class:`~sqlalchemy.schema.Table` construct may be used.  The
-:class:`~sqlalchemy.schema.Column` objects, which in this case require
-their names, will be added to the mapping just like a regular mapping
-to a table::
-
-    class MyClass(Base):
-        __table__ = Table('my_table', Base.metadata,
-            Column('id', Integer, primary_key=True),
-            Column('name', String(50))
-        )
-
-``__table__`` provides a more focused point of control for establishing
-table metadata, while still getting most of the benefits of using declarative.
-An application that uses reflection might want to load table metadata elsewhere
-and pass it to declarative classes::
-
-    from sqlalchemy.ext.declarative import declarative_base
-
-    Base = declarative_base()
-    Base.metadata.reflect(some_engine)
-
-    class User(Base):
-        __table__ = metadata.tables['user']
-
-    class Address(Base):
-        __table__ = metadata.tables['address']
-
-Some configuration schemes may find it more appropriate to use ``__table__``,
-such as those which already take advantage of the data-driven nature of
-:class:`.Table` to customize and/or automate schema definition.
-
-Note that when the ``__table__`` approach is used, the object is immediately
-usable as a plain :class:`.Table` within the class declaration body itself,
-as a Python class is only another syntactical block.  Below this is illustrated
-by using the ``id`` column in the ``primaryjoin`` condition of a
-:func:`.relationship`::
-
-    class MyClass(Base):
-        __table__ = Table('my_table', Base.metadata,
-            Column('id', Integer, primary_key=True),
-            Column('name', String(50))
-        )
-
-        widgets = relationship(Widget,
-                    primaryjoin=Widget.myclass_id==__table__.c.id)
-
-Similarly, mapped attributes which refer to ``__table__`` can be placed inline,
-as below where we assign the ``name`` column to the attribute ``_name``,
-generating a synonym for ``name``::
-
-    from sqlalchemy.ext.declarative import synonym_for
-
-    class MyClass(Base):
-        __table__ = Table('my_table', Base.metadata,
-            Column('id', Integer, primary_key=True),
-            Column('name', String(50))
-        )
-
-        _name = __table__.c.name
-
-        @synonym_for("_name")
-        def name(self):
-            return "Name: %s" % _name
-
-Using Reflection with Declarative
-=================================
-
-It's easy to set up a :class:`.Table` that uses ``autoload=True``
-in conjunction with a mapped class::
-
-    class MyClass(Base):
-        __table__ = Table('mytable', Base.metadata,
-                        autoload=True, autoload_with=some_engine)
-
-However, one improvement that can be made here is to not
-require the :class:`.Engine` to be available when classes are
-being first declared.   To achieve this, use the
-:class:`.DeferredReflection` mixin, which sets up mappings
-only after a special ``prepare(engine)`` step is called::
-
-    from sqlalchemy.ext.declarative import declarative_base, DeferredReflection
-
-    Base = declarative_base(cls=DeferredReflection)
-
-    class Foo(Base):
-        __tablename__ = 'foo'
-        bars = relationship("Bar")
-
-    class Bar(Base):
-        __tablename__ = 'bar'
-
-        # illustrate overriding of "bar.foo_id" to have
-        # a foreign key constraint otherwise not
-        # reflected, such as when using MySQL
-        foo_id = Column(Integer, ForeignKey('foo.id'))
-
-    Base.prepare(e)
-
-.. versionadded:: 0.8
-   Added :class:`.DeferredReflection`.
-
-Mapper Configuration
-====================
-
-Declarative makes use of the :func:`~.orm.mapper` function internally
-when it creates the mapping to the declared table.   The options
-for :func:`~.orm.mapper` are passed directly through via the
-``__mapper_args__`` class attribute.  As always, arguments which reference
-locally mapped columns can reference them directly from within the
-class declaration::
-
-    from datetime import datetime
-
-    class Widget(Base):
-        __tablename__ = 'widgets'
-
-        id = Column(Integer, primary_key=True)
-        timestamp = Column(DateTime, nullable=False)
-
-        __mapper_args__ = {
-                        'version_id_col': timestamp,
-                        'version_id_generator': lambda v:datetime.now()
-                    }
-
-.. _declarative_inheritance:
-
-Inheritance Configuration
-=========================
-
-Declarative supports all three forms of inheritance as intuitively
-as possible.  The ``inherits`` mapper keyword argument is not needed
-as declarative will determine this from the class itself.   The various
-"polymorphic" keyword arguments are specified using ``__mapper_args__``.
-
-Joined Table Inheritance
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-Joined table inheritance is defined as a subclass that defines its own
-table::
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        __tablename__ = 'engineers'
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-        id = Column(Integer, ForeignKey('people.id'), primary_key=True)
-        primary_language = Column(String(50))
-
-Note that above, the ``Engineer.id`` attribute, since it shares the
-same attribute name as the ``Person.id`` attribute, will in fact
-represent the ``people.id`` and ``engineers.id`` columns together,
-with the "Engineer.id" column taking precedence if queried directly.
-To provide the ``Engineer`` class with an attribute that represents
-only the ``engineers.id`` column, give it a different attribute name::
-
-    class Engineer(Person):
-        __tablename__ = 'engineers'
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-        engineer_id = Column('id', Integer, ForeignKey('people.id'),
-                                                    primary_key=True)
-        primary_language = Column(String(50))
-
-
-.. versionchanged:: 0.7 joined table inheritance favors the subclass
-   column over that of the superclass, such as querying above
-   for ``Engineer.id``.  Prior to 0.7 this was the reverse.
-
-.. _declarative_single_table:
-
-Single Table Inheritance
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-Single table inheritance is defined as a subclass that does not have
-its own table; you just leave out the ``__table__`` and ``__tablename__``
-attributes::
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-        primary_language = Column(String(50))
-
-When the above mappers are configured, the ``Person`` class is mapped
-to the ``people`` table *before* the ``primary_language`` column is
-defined, and this column will not be included in its own mapping.
-When ``Engineer`` then defines the ``primary_language`` column, the
-column is added to the ``people`` table so that it is included in the
-mapping for ``Engineer`` and is also part of the table's full set of
-columns.  Columns which are not mapped to ``Person`` are also excluded
-from any other single or joined inheriting classes using the
-``exclude_properties`` mapper argument.  Below, ``Manager`` will have
-all the attributes of ``Person`` and ``Manager`` but *not* the
-``primary_language`` attribute of ``Engineer``::
-
-    class Manager(Person):
-        __mapper_args__ = {'polymorphic_identity': 'manager'}
-        golf_swing = Column(String(50))
-
-The attribute exclusion logic is provided by the
-``exclude_properties`` mapper argument, and declarative's default
-behavior can be disabled by passing an explicit ``exclude_properties``
-collection (empty or otherwise) to the ``__mapper_args__``.
-
-Resolving Column Conflicts
-^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Note above that the ``primary_language`` and ``golf_swing`` columns
-are "moved up" to be applied to ``Person.__table__``, as a result of their
-declaration on a subclass that has no table of its own.   A tricky case
-comes up when two subclasses want to specify *the same* column, as below::
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-        start_date = Column(DateTime)
-
-    class Manager(Person):
-        __mapper_args__ = {'polymorphic_identity': 'manager'}
-        start_date = Column(DateTime)
-
-Above, the ``start_date`` column declared on both ``Engineer`` and ``Manager``
-will result in an error::
-
-    sqlalchemy.exc.ArgumentError: Column 'start_date' on class
-    <class '__main__.Manager'> conflicts with existing
-    column 'people.start_date'
-
-In a situation like this, Declarative can't be sure
-of the intent, especially if the ``start_date`` columns had, for example,
-different types.   A situation like this can be resolved by using
-:class:`.declared_attr` to define the :class:`.Column` conditionally, taking
-care to return the **existing column** via the parent ``__table__`` if it
-already exists::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-
-        @declared_attr
-        def start_date(cls):
-            "Start date column, if not present already."
-            return Person.__table__.c.get('start_date', Column(DateTime))
-
-    class Manager(Person):
-        __mapper_args__ = {'polymorphic_identity': 'manager'}
-
-        @declared_attr
-        def start_date(cls):
-            "Start date column, if not present already."
-            return Person.__table__.c.get('start_date', Column(DateTime))
-
-Above, when ``Manager`` is mapped, the ``start_date`` column is
-already present on the ``Person`` class.  Declarative lets us return
-that :class:`.Column` as a result in this case, where it knows to skip
-re-assigning the same column. If the mapping is mis-configured such
-that the ``start_date`` column is accidentally re-assigned to a
-different table (such as, if we changed ``Manager`` to be joined
-inheritance without fixing ``start_date``), an error is raised which
-indicates an existing :class:`.Column` is trying to be re-assigned to
-a different owning :class:`.Table`.
-
-.. versionadded:: 0.8 :class:`.declared_attr` can be used on a non-mixin
-   class, and the returned :class:`.Column` or other mapped attribute
-   will be applied to the mapping as any other attribute.  Previously,
-   the resulting attribute would be ignored, and also result in a warning
-   being emitted when a subclass was created.
-
-.. versionadded:: 0.8 :class:`.declared_attr`, when used either with a
-   mixin or non-mixin declarative class, can return an existing
-   :class:`.Column` already assigned to the parent :class:`.Table`,
-   to indicate that the re-assignment of the :class:`.Column` should be
-   skipped, however should still be mapped on the target class,
-   in order to resolve duplicate column conflicts.
-
-The same concept can be used with mixin classes (see
-:ref:`declarative_mixins`)::
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class HasStartDate(object):
-        @declared_attr
-        def start_date(cls):
-            return cls.__table__.c.get('start_date', Column(DateTime))
-
-    class Engineer(HasStartDate, Person):
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-
-    class Manager(HasStartDate, Person):
-        __mapper_args__ = {'polymorphic_identity': 'manager'}
-
-The above mixin checks the local ``__table__`` attribute for the column.
-Because we're using single table inheritance, we're sure that in this case,
-``cls.__table__`` refers to ``People.__table__``.  If we were mixing joined-
-and single-table inheritance, we might want our mixin to check more carefully
-if ``cls.__table__`` is really the :class:`.Table` we're looking for.
-
-Concrete Table Inheritance
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Concrete is defined as a subclass which has its own table and sets the
-``concrete`` keyword argument to ``True``::
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        name = Column(String(50))
-
-    class Engineer(Person):
-        __tablename__ = 'engineers'
-        __mapper_args__ = {'concrete':True}
-        id = Column(Integer, primary_key=True)
-        primary_language = Column(String(50))
-        name = Column(String(50))
-
-Usage of an abstract base class is a little less straightforward as it
-requires usage of :func:`~sqlalchemy.orm.util.polymorphic_union`,
-which needs to be created with the :class:`.Table` objects
-before the class is built::
-
-    engineers = Table('engineers', Base.metadata,
-                    Column('id', Integer, primary_key=True),
-                    Column('name', String(50)),
-                    Column('primary_language', String(50))
-                )
-    managers = Table('managers', Base.metadata,
-                    Column('id', Integer, primary_key=True),
-                    Column('name', String(50)),
-                    Column('golf_swing', String(50))
-                )
-
-    punion = polymorphic_union({
-        'engineer':engineers,
-        'manager':managers
-    }, 'type', 'punion')
-
-    class Person(Base):
-        __table__ = punion
-        __mapper_args__ = {'polymorphic_on':punion.c.type}
-
-    class Engineer(Person):
-        __table__ = engineers
-        __mapper_args__ = {'polymorphic_identity':'engineer', 'concrete':True}
-
-    class Manager(Person):
-        __table__ = managers
-        __mapper_args__ = {'polymorphic_identity':'manager', 'concrete':True}
-
-.. _declarative_concrete_helpers:
-
-Using the Concrete Helpers
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Helper classes provides a simpler pattern for concrete inheritance.
-With these objects, the ``__declare_first__`` helper is used to configure the
-"polymorphic" loader for the mapper after all subclasses have been declared.
-
-.. versionadded:: 0.7.3
-
-An abstract base can be declared using the
-:class:`.AbstractConcreteBase` class::
-
-    from sqlalchemy.ext.declarative import AbstractConcreteBase
-
-    class Employee(AbstractConcreteBase, Base):
-        pass
-
-To have a concrete ``employee`` table, use :class:`.ConcreteBase` instead::
-
-    from sqlalchemy.ext.declarative import ConcreteBase
-
-    class Employee(ConcreteBase, Base):
-        __tablename__ = 'employee'
-        employee_id = Column(Integer, primary_key=True)
-        name = Column(String(50))
-        __mapper_args__ = {
-                        'polymorphic_identity':'employee',
-                        'concrete':True}
-
-
-Either ``Employee`` base can be used in the normal fashion::
-
-    class Manager(Employee):
-        __tablename__ = 'manager'
-        employee_id = Column(Integer, primary_key=True)
-        name = Column(String(50))
-        manager_data = Column(String(40))
-        __mapper_args__ = {
-                        'polymorphic_identity':'manager',
-                        'concrete':True}
-
-    class Engineer(Employee):
-        __tablename__ = 'engineer'
-        employee_id = Column(Integer, primary_key=True)
-        name = Column(String(50))
-        engineer_info = Column(String(40))
-        __mapper_args__ = {'polymorphic_identity':'engineer',
-                        'concrete':True}
-
-
-The :class:`.AbstractConcreteBase` class is itself mapped, and can be
-used as a target of relationships::
-
-    class Company(Base):
-        __tablename__ = 'company'
-
-        id = Column(Integer, primary_key=True)
-        employees = relationship("Employee",
-                        primaryjoin="Company.id == Employee.company_id")
-
-
-.. versionchanged:: 0.9.3 Support for use of :class:`.AbstractConcreteBase`
-   as the target of a :func:`.relationship` has been improved.
-
-It can also be queried directly::
-
-    for employee in session.query(Employee).filter(Employee.name == 'qbert'):
-        print(employee)
-
-
-.. _declarative_mixins:
-
-Mixin and Custom Base Classes
-==============================
-
-A common need when using :mod:`~sqlalchemy.ext.declarative` is to
-share some functionality, such as a set of common columns, some common
-table options, or other mapped properties, across many
-classes.  The standard Python idioms for this is to have the classes
-inherit from a base which includes these common features.
-
-When using :mod:`~sqlalchemy.ext.declarative`, this idiom is allowed
-via the usage of a custom declarative base class, as well as a "mixin" class
-which is inherited from in addition to the primary base.  Declarative
-includes several helper features to make this work in terms of how
-mappings are declared.   An example of some commonly mixed-in
-idioms is below::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class MyMixin(object):
-
-        @declared_attr
-        def __tablename__(cls):
-            return cls.__name__.lower()
-
-        __table_args__ = {'mysql_engine': 'InnoDB'}
-        __mapper_args__= {'always_refresh': True}
-
-        id =  Column(Integer, primary_key=True)
-
-    class MyModel(MyMixin, Base):
-        name = Column(String(1000))
-
-Where above, the class ``MyModel`` will contain an "id" column
-as the primary key, a ``__tablename__`` attribute that derives
-from the name of the class itself, as well as ``__table_args__``
-and ``__mapper_args__`` defined by the ``MyMixin`` mixin class.
-
-There's no fixed convention over whether ``MyMixin`` precedes
-``Base`` or not.  Normal Python method resolution rules apply, and
-the above example would work just as well with::
-
-    class MyModel(Base, MyMixin):
-        name = Column(String(1000))
-
-This works because ``Base`` here doesn't define any of the
-variables that ``MyMixin`` defines, i.e. ``__tablename__``,
-``__table_args__``, ``id``, etc.   If the ``Base`` did define
-an attribute of the same name, the class placed first in the
-inherits list would determine which attribute is used on the
-newly defined class.
-
-Augmenting the Base
-~~~~~~~~~~~~~~~~~~~
-
-In addition to using a pure mixin, most of the techniques in this
-section can also be applied to the base class itself, for patterns that
-should apply to all classes derived from a particular base.  This is achieved
-using the ``cls`` argument of the :func:`.declarative_base` function::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class Base(object):
-        @declared_attr
-        def __tablename__(cls):
-            return cls.__name__.lower()
-
-        __table_args__ = {'mysql_engine': 'InnoDB'}
-
-        id =  Column(Integer, primary_key=True)
-
-    from sqlalchemy.ext.declarative import declarative_base
-
-    Base = declarative_base(cls=Base)
-
-    class MyModel(Base):
-        name = Column(String(1000))
-
-Where above, ``MyModel`` and all other classes that derive from ``Base`` will
-have a table name derived from the class name, an ``id`` primary key column,
-as well as the "InnoDB" engine for MySQL.
-
-Mixing in Columns
-~~~~~~~~~~~~~~~~~
-
-The most basic way to specify a column on a mixin is by simple
-declaration::
-
-    class TimestampMixin(object):
-        created_at = Column(DateTime, default=func.now())
-
-    class MyModel(TimestampMixin, Base):
-        __tablename__ = 'test'
-
-        id =  Column(Integer, primary_key=True)
-        name = Column(String(1000))
-
-Where above, all declarative classes that include ``TimestampMixin``
-will also have a column ``created_at`` that applies a timestamp to
-all row insertions.
-
-Those familiar with the SQLAlchemy expression language know that
-the object identity of clause elements defines their role in a schema.
-Two ``Table`` objects ``a`` and ``b`` may both have a column called
-``id``, but the way these are differentiated is that ``a.c.id``
-and ``b.c.id`` are two distinct Python objects, referencing their
-parent tables ``a`` and ``b`` respectively.
-
-In the case of the mixin column, it seems that only one
-:class:`.Column` object is explicitly created, yet the ultimate
-``created_at`` column above must exist as a distinct Python object
-for each separate destination class.  To accomplish this, the declarative
-extension creates a **copy** of each :class:`.Column` object encountered on
-a class that is detected as a mixin.
-
-This copy mechanism is limited to simple columns that have no foreign
-keys, as a :class:`.ForeignKey` itself contains references to columns
-which can't be properly recreated at this level.  For columns that
-have foreign keys, as well as for the variety of mapper-level constructs
-that require destination-explicit context, the
-:class:`~.declared_attr` decorator is provided so that
-patterns common to many classes can be defined as callables::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class ReferenceAddressMixin(object):
-        @declared_attr
-        def address_id(cls):
-            return Column(Integer, ForeignKey('address.id'))
-
-    class User(ReferenceAddressMixin, Base):
-        __tablename__ = 'user'
-        id = Column(Integer, primary_key=True)
-
-Where above, the ``address_id`` class-level callable is executed at the
-point at which the ``User`` class is constructed, and the declarative
-extension can use the resulting :class:`.Column` object as returned by
-the method without the need to copy it.
-
-.. versionchanged:: > 0.6.5
-    Rename 0.6.5 ``sqlalchemy.util.classproperty``
-    into :class:`~.declared_attr`.
-
-Columns generated by :class:`~.declared_attr` can also be
-referenced by ``__mapper_args__`` to a limited degree, currently
-by ``polymorphic_on`` and ``version_id_col``, by specifying the
-classdecorator itself into the dictionary - the declarative extension
-will resolve them at class construction time::
-
-    class MyMixin:
-        @declared_attr
-        def type_(cls):
-            return Column(String(50))
-
-        __mapper_args__= {'polymorphic_on':type_}
-
-    class MyModel(MyMixin, Base):
-        __tablename__='test'
-        id =  Column(Integer, primary_key=True)
-
-
-
-Mixing in Relationships
-~~~~~~~~~~~~~~~~~~~~~~~
-
-Relationships created by :func:`~sqlalchemy.orm.relationship` are provided
-with declarative mixin classes exclusively using the
-:class:`.declared_attr` approach, eliminating any ambiguity
-which could arise when copying a relationship and its possibly column-bound
-contents. Below is an example which combines a foreign key column and a
-relationship so that two classes ``Foo`` and ``Bar`` can both be configured to
-reference a common target class via many-to-one::
-
-    class RefTargetMixin(object):
-        @declared_attr
-        def target_id(cls):
-            return Column('target_id', ForeignKey('target.id'))
-
-        @declared_attr
-        def target(cls):
-            return relationship("Target")
-
-    class Foo(RefTargetMixin, Base):
-        __tablename__ = 'foo'
-        id = Column(Integer, primary_key=True)
-
-    class Bar(RefTargetMixin, Base):
-        __tablename__ = 'bar'
-        id = Column(Integer, primary_key=True)
-
-    class Target(Base):
-        __tablename__ = 'target'
-        id = Column(Integer, primary_key=True)
-
-Using Advanced Relationship Arguments (e.g. ``primaryjoin``, etc.)
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-:func:`~sqlalchemy.orm.relationship` definitions which require explicit
-primaryjoin, order_by etc. expressions should in all but the most
-simplistic cases use **late bound** forms
-for these arguments, meaning, using either the string form or a lambda.
-The reason for this is that the related :class:`.Column` objects which are to
-be configured using ``@declared_attr`` are not available to another
-``@declared_attr`` attribute; while the methods will work and return new
-:class:`.Column` objects, those are not the :class:`.Column` objects that
-Declarative will be using as it calls the methods on its own, thus using
-*different* :class:`.Column` objects.
-
-The canonical example is the primaryjoin condition that depends upon
-another mixed-in column::
-
-    class RefTargetMixin(object):
-        @declared_attr
-        def target_id(cls):
-            return Column('target_id', ForeignKey('target.id'))
-
-        @declared_attr
-        def target(cls):
-            return relationship(Target,
-                primaryjoin=Target.id==cls.target_id   # this is *incorrect*
-            )
-
-Mapping a class using the above mixin, we will get an error like::
-
-    sqlalchemy.exc.InvalidRequestError: this ForeignKey's parent column is not
-    yet associated with a Table.
-
-This is because the ``target_id`` :class:`.Column` we've called upon in our ``target()``
-method is not the same :class:`.Column` that declarative is actually going to map
-to our table.
-
-The condition above is resolved using a lambda::
-
-    class RefTargetMixin(object):
-        @declared_attr
-        def target_id(cls):
-            return Column('target_id', ForeignKey('target.id'))
-
-        @declared_attr
-        def target(cls):
-            return relationship(Target,
-                primaryjoin=lambda: Target.id==cls.target_id
-            )
-
-or alternatively, the string form (which ultmately generates a lambda)::
-
-    class RefTargetMixin(object):
-        @declared_attr
-        def target_id(cls):
-            return Column('target_id', ForeignKey('target.id'))
-
-        @declared_attr
-        def target(cls):
-            return relationship("Target",
-                primaryjoin="Target.id==%s.target_id" % cls.__name__
-            )
-
-Mixing in deferred(), column_property(), and other MapperProperty classes
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Like :func:`~sqlalchemy.orm.relationship`, all
-:class:`~sqlalchemy.orm.interfaces.MapperProperty` subclasses such as
-:func:`~sqlalchemy.orm.deferred`, :func:`~sqlalchemy.orm.column_property`,
-etc. ultimately involve references to columns, and therefore, when
-used with declarative mixins, have the :class:`.declared_attr`
-requirement so that no reliance on copying is needed::
-
-    class SomethingMixin(object):
-
-        @declared_attr
-        def dprop(cls):
-            return deferred(Column(Integer))
-
-    class Something(SomethingMixin, Base):
-        __tablename__ = "something"
-
-Mixing in Association Proxy and Other Attributes
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Mixins can specify user-defined attributes as well as other extension
-units such as :func:`.association_proxy`.   The usage of
-:class:`.declared_attr` is required in those cases where the attribute must
-be tailored specifically to the target subclass.   An example is when
-constructing multiple :func:`.association_proxy` attributes which each
-target a different type of child object.  Below is an
-:func:`.association_proxy` / mixin example which provides a scalar list of
-string values to an implementing class::
-
-    from sqlalchemy import Column, Integer, ForeignKey, String
-    from sqlalchemy.orm import relationship
-    from sqlalchemy.ext.associationproxy import association_proxy
-    from sqlalchemy.ext.declarative import declarative_base, declared_attr
-
-    Base = declarative_base()
-
-    class HasStringCollection(object):
-        @declared_attr
-        def _strings(cls):
-            class StringAttribute(Base):
-                __tablename__ = cls.string_table_name
-                id = Column(Integer, primary_key=True)
-                value = Column(String(50), nullable=False)
-                parent_id = Column(Integer,
-                                ForeignKey('%s.id' % cls.__tablename__),
-                                nullable=False)
-                def __init__(self, value):
-                    self.value = value
-
-            return relationship(StringAttribute)
-
-        @declared_attr
-        def strings(cls):
-            return association_proxy('_strings', 'value')
-
-    class TypeA(HasStringCollection, Base):
-        __tablename__ = 'type_a'
-        string_table_name = 'type_a_strings'
-        id = Column(Integer(), primary_key=True)
-
-    class TypeB(HasStringCollection, Base):
-        __tablename__ = 'type_b'
-        string_table_name = 'type_b_strings'
-        id = Column(Integer(), primary_key=True)
-
-Above, the ``HasStringCollection`` mixin produces a :func:`.relationship`
-which refers to a newly generated class called ``StringAttribute``.  The
-``StringAttribute`` class is generated with it's own :class:`.Table`
-definition which is local to the parent class making usage of the
-``HasStringCollection`` mixin.  It also produces an :func:`.association_proxy`
-object which proxies references to the ``strings`` attribute onto the ``value``
-attribute of each ``StringAttribute`` instance.
-
-``TypeA`` or ``TypeB`` can be instantiated given the constructor
-argument ``strings``, a list of strings::
-
-    ta = TypeA(strings=['foo', 'bar'])
-    tb = TypeA(strings=['bat', 'bar'])
-
-This list will generate a collection
-of ``StringAttribute`` objects, which are persisted into a table that's
-local to either the ``type_a_strings`` or ``type_b_strings`` table::
-
-    >>> print ta._strings
-    [<__main__.StringAttribute object at 0x10151cd90>,
-        <__main__.StringAttribute object at 0x10151ce10>]
-
-When constructing the :func:`.association_proxy`, the
-:class:`.declared_attr` decorator must be used so that a distinct
-:func:`.association_proxy` object is created for each of the ``TypeA``
-and ``TypeB`` classes.
-
-.. versionadded:: 0.8 :class:`.declared_attr` is usable with non-mapped
-   attributes, including user-defined attributes as well as
-   :func:`.association_proxy`.
-
-
-Controlling table inheritance with mixins
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The ``__tablename__`` attribute in conjunction with the hierarchy of
-classes involved in a declarative mixin scenario controls what type of
-table inheritance, if any,
-is configured by the declarative extension.
-
-If the ``__tablename__`` is computed by a mixin, you may need to
-control which classes get the computed attribute in order to get the
-type of table inheritance you require.
-
-For example, if you had a mixin that computes ``__tablename__`` but
-where you wanted to use that mixin in a single table inheritance
-hierarchy, you can explicitly specify ``__tablename__`` as ``None`` to
-indicate that the class should not have a table mapped::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class Tablename:
-        @declared_attr
-        def __tablename__(cls):
-            return cls.__name__.lower()
-
-    class Person(Tablename, Base):
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        __tablename__ = None
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-        primary_language = Column(String(50))
-
-Alternatively, you can make the mixin intelligent enough to only
-return a ``__tablename__`` in the event that no table is already
-mapped in the inheritance hierarchy. To help with this, a
-:func:`~sqlalchemy.ext.declarative.has_inherited_table` helper
-function is provided that returns ``True`` if a parent class already
-has a mapped table.
-
-As an example, here's a mixin that will only allow single table
-inheritance::
-
-    from sqlalchemy.ext.declarative import declared_attr
-    from sqlalchemy.ext.declarative import has_inherited_table
-
-    class Tablename(object):
-        @declared_attr
-        def __tablename__(cls):
-            if has_inherited_table(cls):
-                return None
-            return cls.__name__.lower()
-
-    class Person(Tablename, Base):
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        primary_language = Column(String(50))
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-
-
-Combining Table/Mapper Arguments from Multiple Mixins
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-In the case of ``__table_args__`` or ``__mapper_args__``
-specified with declarative mixins, you may want to combine
-some parameters from several mixins with those you wish to
-define on the class iteself. The
-:class:`.declared_attr` decorator can be used
-here to create user-defined collation routines that pull
-from multiple collections::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class MySQLSettings(object):
-        __table_args__ = {'mysql_engine':'InnoDB'}
-
-    class MyOtherMixin(object):
-        __table_args__ = {'info':'foo'}
-
-    class MyModel(MySQLSettings, MyOtherMixin, Base):
-        __tablename__='my_model'
-
-        @declared_attr
-        def __table_args__(cls):
-            args = dict()
-            args.update(MySQLSettings.__table_args__)
-            args.update(MyOtherMixin.__table_args__)
-            return args
-
-        id =  Column(Integer, primary_key=True)
-
-Creating Indexes with Mixins
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-To define a named, potentially multicolumn :class:`.Index` that applies to all
-tables derived from a mixin, use the "inline" form of :class:`.Index` and
-establish it as part of ``__table_args__``::
-
-    class MyMixin(object):
-        a =  Column(Integer)
-        b =  Column(Integer)
-
-        @declared_attr
-        def __table_args__(cls):
-            return (Index('test_idx_%s' % cls.__tablename__, 'a', 'b'),)
-
-    class MyModel(MyMixin, Base):
-        __tablename__ = 'atable'
-        c =  Column(Integer,primary_key=True)
-
-Special Directives
-==================
-
-``__declare_last__()``
-~~~~~~~~~~~~~~~~~~~~~~
-
-The ``__declare_last__()`` hook allows definition of
-a class level function that is automatically called by the
-:meth:`.MapperEvents.after_configured` event, which occurs after mappings are
-assumed to be completed and the 'configure' step has finished::
-
-    class MyClass(Base):
-        @classmethod
-        def __declare_last__(cls):
-            ""
-            # do something with mappings
-
-.. versionadded:: 0.7.3
-
-``__declare_first__()``
-~~~~~~~~~~~~~~~~~~~~~~~
-
-Like ``__declare_last__()``, but is called at the beginning of mapper configuration
-via the :meth:`.MapperEvents.before_configured` event::
-
-    class MyClass(Base):
-        @classmethod
-        def __declare_first__(cls):
-            ""
-            # do something before mappings are configured
-
-.. versionadded:: 0.9.3
-
-.. _declarative_abstract:
-
-``__abstract__``
-~~~~~~~~~~~~~~~~~~~
-
-``__abstract__`` causes declarative to skip the production
-of a table or mapper for the class entirely.  A class can be added within a
-hierarchy in the same way as mixin (see :ref:`declarative_mixins`), allowing
-subclasses to extend just from the special class::
-
-    class SomeAbstractBase(Base):
-        __abstract__ = True
-
-        def some_helpful_method(self):
-            ""
-
-        @declared_attr
-        def __mapper_args__(cls):
-            return {"helpful mapper arguments":True}
-
-    class MyMappedClass(SomeAbstractBase):
-        ""
-
-One possible use of ``__abstract__`` is to use a distinct
-:class:`.MetaData` for different bases::
-
-    Base = declarative_base()
-
-    class DefaultBase(Base):
-        __abstract__ = True
-        metadata = MetaData()
-
-    class OtherBase(Base):
-        __abstract__ = True
-        metadata = MetaData()
-
-Above, classes which inherit from ``DefaultBase`` will use one
-:class:`.MetaData` as the registry of tables, and those which inherit from
-``OtherBase`` will use a different one. The tables themselves can then be
-created perhaps within distinct databases::
-
-    DefaultBase.metadata.create_all(some_engine)
-    OtherBase.metadata_create_all(some_other_engine)
-
-.. versionadded:: 0.7.3
-
-Class Constructor
-=================
-
-As a convenience feature, the :func:`declarative_base` sets a default
-constructor on classes which takes keyword arguments, and assigns them
-to the named attributes::
-
-    e = Engineer(primary_language='python')
-
-Sessions
-========
-
-Note that ``declarative`` does nothing special with sessions, and is
-only intended as an easier way to configure mappers and
-:class:`~sqlalchemy.schema.Table` objects.  A typical application
-setup using :class:`~sqlalchemy.orm.scoping.scoped_session` might look like::
-
-    engine = create_engine('postgresql://scott:tiger@localhost/test')
-    Session = scoped_session(sessionmaker(autocommit=False,
-                                          autoflush=False,
-                                          bind=engine))
-    Base = declarative_base()
-
-Mapped instances then make usage of
-:class:`~sqlalchemy.orm.session.Session` in the usual way.

-class DeferredReflection(object):
-    """A helper class for construction of mappings based on
-    a deferred reflection step.
-
-    Normally, declarative can be used with reflection by
-    setting a :class:`.Table` object using autoload=True
-    as the ``__table__`` attribute on a declarative class.
-    The caveat is that the :class:`.Table` must be fully
-    reflected, or at the very least have a primary key column,
-    at the point at which a normal declarative mapping is
-    constructed, meaning the :class:`.Engine` must be available
-    at class declaration time.
-
-    The :class:`.DeferredReflection` mixin moves the construction
-    of mappers to be at a later point, after a specific
-    method is called which first reflects all :class:`.Table`
-    objects created so far.   Classes can define it as such::
-
-        from sqlalchemy.ext.declarative import declarative_base
-        from sqlalchemy.ext.declarative import DeferredReflection
-        Base = declarative_base()
-
-        class MyClass(DeferredReflection, Base):
-            __tablename__ = 'mytable'
-
-    Above, ``MyClass`` is not yet mapped.   After a series of
-    classes have been defined in the above fashion, all tables
-    can be reflected and mappings created using
-    :meth:`.prepare`::
-
-        engine = create_engine("someengine://...")
-        DeferredReflection.prepare(engine)
-
-    The :class:`.DeferredReflection` mixin can be applied to individual
-    classes, used as the base for the declarative base itself,
-    or used in a custom abstract class.   Using an abstract base
-    allows that only a subset of classes to be prepared for a
-    particular prepare step, which is necessary for applications
-    that use more than one engine.  For example, if an application
-    has two engines, you might use two bases, and prepare each
-    separately, e.g.::
-
-        class ReflectedOne(DeferredReflection, Base):
-            __abstract__ = True
-
-        class ReflectedTwo(DeferredReflection, Base):
-            __abstract__ = True
-
-        class MyClass(ReflectedOne):
-            __tablename__ = 'mytable'
-
-        class MyOtherClass(ReflectedOne):
-            __tablename__ = 'myothertable'
-
-        class YetAnotherClass(ReflectedTwo):
-            __tablename__ = 'yetanothertable'
-
-        # ... etc.
-
-    Above, the class hierarchies for ``ReflectedOne`` and
-    ``ReflectedTwo`` can be configured separately::
-
-        ReflectedOne.prepare(engine_one)
-        ReflectedTwo.prepare(engine_two)

-    .. versionadded:: 0.8

-"""Define attributes on ORM-mapped classes that have "hybrid" behavior.
-
-"hybrid" means the attribute has distinct behaviors defined at the
-class level and at the instance level.
-
-The :mod:`~sqlalchemy.ext.hybrid` extension provides a special form of
-method decorator, is around 50 lines of code and has almost no
-dependencies on the rest of SQLAlchemy.  It can, in theory, work with
-any descriptor-based expression system.
-
-Consider a mapping ``Interval``, representing integer ``start`` and ``end``
-values. We can define higher level functions on mapped classes that produce
-SQL expressions at the class level, and Python expression evaluation at the
-instance level.  Below, each function decorated with :class:`.hybrid_method` or
-:class:`.hybrid_property` may receive ``self`` as an instance of the class, or
-as the class itself::
-
-    from sqlalchemy import Column, Integer
-    from sqlalchemy.ext.declarative import declarative_base
-    from sqlalchemy.orm import Session, aliased
-    from sqlalchemy.ext.hybrid import hybrid_property, hybrid_method
-
-    Base = declarative_base()
-
-    class Interval(Base):
-        __tablename__ = 'interval'
-
-        id = Column(Integer, primary_key=True)
-        start = Column(Integer, nullable=False)
-        end = Column(Integer, nullable=False)
-
-        def __init__(self, start, end):
-            self.start = start
-            self.end = end
-
-        @hybrid_property
-        def length(self):
-            return self.end - self.start
-
-        @hybrid_method
-        def contains(self,point):
-            return (self.start <= point) & (point < self.end)
-
-        @hybrid_method
-        def intersects(self, other):
-            return self.contains(other.start) | self.contains(other.end)
-
-Above, the ``length`` property returns the difference between the
-``end`` and ``start`` attributes.  With an instance of ``Interval``,
-this subtraction occurs in Python, using normal Python descriptor
-mechanics::
-
-    >>> i1 = Interval(5, 10)
-    >>> i1.length
-    5
-
-When dealing with the ``Interval`` class itself, the :class:`.hybrid_property`
-descriptor evaluates the function body given the ``Interval`` class as
-the argument, which when evaluated with SQLAlchemy expression mechanics
-returns a new SQL expression::
-
-    >>> print Interval.length
-    interval."end" - interval.start
-
-    >>> print Session().query(Interval).filter(Interval.length > 10)
-    SELECT interval.id AS interval_id, interval.start AS interval_start,
-    interval."end" AS interval_end
-    FROM interval
-    WHERE interval."end" - interval.start > :param_1
-
-ORM methods such as :meth:`~.Query.filter_by` generally use ``getattr()`` to
-locate attributes, so can also be used with hybrid attributes::
-
-    >>> print Session().query(Interval).filter_by(length=5)
-    SELECT interval.id AS interval_id, interval.start AS interval_start,
-    interval."end" AS interval_end
-    FROM interval
-    WHERE interval."end" - interval.start = :param_1
-
-The ``Interval`` class example also illustrates two methods,
-``contains()`` and ``intersects()``, decorated with
-:class:`.hybrid_method`. This decorator applies the same idea to
-methods that :class:`.hybrid_property` applies to attributes.   The
-methods return boolean values, and take advantage of the Python ``|``
-and ``&`` bitwise operators to produce equivalent instance-level and
-SQL expression-level boolean behavior::
-
-    >>> i1.contains(6)
-    True
-    >>> i1.contains(15)
-    False
-    >>> i1.intersects(Interval(7, 18))
-    True
-    >>> i1.intersects(Interval(25, 29))
-    False
-
-    >>> print Session().query(Interval).filter(Interval.contains(15))
-    SELECT interval.id AS interval_id, interval.start AS interval_start,
-    interval."end" AS interval_end
-    FROM interval
-    WHERE interval.start <= :start_1 AND interval."end" > :end_1
-
-    >>> ia = aliased(Interval)
-    >>> print Session().query(Interval, ia).filter(Interval.intersects(ia))
-    SELECT interval.id AS interval_id, interval.start AS interval_start,
-    interval."end" AS interval_end, interval_1.id AS interval_1_id,
-    interval_1.start AS interval_1_start, interval_1."end" AS interval_1_end
-    FROM interval, interval AS interval_1
-    WHERE interval.start <= interval_1.start
-        AND interval."end" > interval_1.start
-        OR interval.start <= interval_1."end"
-        AND interval."end" > interval_1."end"
-
-Defining Expression Behavior Distinct from Attribute Behavior
---------------------------------------------------------------
-
-Our usage of the ``&`` and ``|`` bitwise operators above was
-fortunate, considering our functions operated on two boolean values to
-return a new one.   In many cases, the construction of an in-Python
-function and a SQLAlchemy SQL expression have enough differences that
-two separate Python expressions should be defined.  The
-:mod:`~sqlalchemy.ext.hybrid` decorators define the
-:meth:`.hybrid_property.expression` modifier for this purpose.   As an
-example we'll define the radius of the interval, which requires the
-usage of the absolute value function::
-
-    from sqlalchemy import func
-
-    class Interval(object):
-        # ...
-
-        @hybrid_property
-        def radius(self):
-            return abs(self.length) / 2
-
-        @radius.expression
-        def radius(cls):
-            return func.abs(cls.length) / 2
-
-Above the Python function ``abs()`` is used for instance-level
-operations, the SQL function ``ABS()`` is used via the :attr:`.func`
-object for class-level expressions::
-
-    >>> i1.radius
-    2
-
-    >>> print Session().query(Interval).filter(Interval.radius > 5)
-    SELECT interval.id AS interval_id, interval.start AS interval_start,
-        interval."end" AS interval_end
-    FROM interval
-    WHERE abs(interval."end" - interval.start) / :abs_1 > :param_1
-
-Defining Setters
-----------------
-
-Hybrid properties can also define setter methods.  If we wanted
-``length`` above, when set, to modify the endpoint value::
-
-    class Interval(object):
-        # ...
-
-        @hybrid_property
-        def length(self):
-            return self.end - self.start
-
-        @length.setter
-        def length(self, value):
-            self.end = self.start + value
-
-The ``length(self, value)`` method is now called upon set::
-
-    >>> i1 = Interval(5, 10)
-    >>> i1.length
-    5
-    >>> i1.length = 12
-    >>> i1.end

-
-Working with Relationships
---------------------------
-
-There's no essential difference when creating hybrids that work with
-related objects as opposed to column-based data. The need for distinct
-expressions tends to be greater.  Two variants of we'll illustrate
-are the "join-dependent" hybrid, and the "correlated subquery" hybrid.
-
-Join-Dependent Relationship Hybrid
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Consider the following declarative
-mapping which relates a ``User`` to a ``SavingsAccount``::
-
-    from sqlalchemy import Column, Integer, ForeignKey, Numeric, String
-    from sqlalchemy.orm import relationship
-    from sqlalchemy.ext.declarative import declarative_base
-    from sqlalchemy.ext.hybrid import hybrid_property
-
-    Base = declarative_base()
-
-    class SavingsAccount(Base):
-        __tablename__ = 'account'
-        id = Column(Integer, primary_key=True)
-        user_id = Column(Integer, ForeignKey('user.id'), nullable=False)
-        balance = Column(Numeric(15, 5))
-
-    class User(Base):
-        __tablename__ = 'user'
-        id = Column(Integer, primary_key=True)
-        name = Column(String(100), nullable=False)
-
-        accounts = relationship("SavingsAccount", backref="owner")
-
-        @hybrid_property
-        def balance(self):
-            if self.accounts:
-                return self.accounts[0].balance
-            else:
-                return None
-
-        @balance.setter
-        def balance(self, value):
-            if not self.accounts:
-                account = Account(owner=self)
-            else:
-                account = self.accounts[0]
-            account.balance = value
-
-        @balance.expression
-        def balance(cls):
-            return SavingsAccount.balance
-
-The above hybrid property ``balance`` works with the first
-``SavingsAccount`` entry in the list of accounts for this user.   The
-in-Python getter/setter methods can treat ``accounts`` as a Python
-list available on ``self``.
-
-However, at the expression level, it's expected that the ``User`` class will
-be used in an appropriate context such that an appropriate join to
-``SavingsAccount`` will be present::
-
-    >>> print Session().query(User, User.balance).\\
-    ...     join(User.accounts).filter(User.balance > 5000)
-    SELECT "user".id AS user_id, "user".name AS user_name,
-    account.balance AS account_balance
-    FROM "user" JOIN account ON "user".id = account.user_id
-    WHERE account.balance > :balance_1
-
-Note however, that while the instance level accessors need to worry
-about whether ``self.accounts`` is even present, this issue expresses
-itself differently at the SQL expression level, where we basically
-would use an outer join::
-
-    >>> from sqlalchemy import or_
-    >>> print (Session().query(User, User.balance).outerjoin(User.accounts).
-    ...         filter(or_(User.balance < 5000, User.balance == None)))
-    SELECT "user".id AS user_id, "user".name AS user_name,
-    account.balance AS account_balance
-    FROM "user" LEFT OUTER JOIN account ON "user".id = account.user_id
-    WHERE account.balance <  :balance_1 OR account.balance IS NULL
-
-Correlated Subquery Relationship Hybrid
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-We can, of course, forego being dependent on the enclosing query's usage
-of joins in favor of the correlated subquery, which can portably be packed
-into a single column expression. A correlated subquery is more portable, but
-often performs more poorly at the SQL level. Using the same technique
-illustrated at :ref:`mapper_column_property_sql_expressions`,
-we can adjust our ``SavingsAccount`` example to aggregate the balances for
-*all* accounts, and use a correlated subquery for the column expression::
-
-    from sqlalchemy import Column, Integer, ForeignKey, Numeric, String
-    from sqlalchemy.orm import relationship
-    from sqlalchemy.ext.declarative import declarative_base
-    from sqlalchemy.ext.hybrid import hybrid_property
-    from sqlalchemy import select, func
-
-    Base = declarative_base()
-
-    class SavingsAccount(Base):
-        __tablename__ = 'account'
-        id = Column(Integer, primary_key=True)
-        user_id = Column(Integer, ForeignKey('user.id'), nullable=False)
-        balance = Column(Numeric(15, 5))
-
-    class User(Base):
-        __tablename__ = 'user'
-        id = Column(Integer, primary_key=True)
-        name = Column(String(100), nullable=False)
-
-        accounts = relationship("SavingsAccount", backref="owner")
-
-        @hybrid_property
-        def balance(self):
-            return sum(acc.balance for acc in self.accounts)
-
-        @balance.expression
-        def balance(cls):
-            return select([func.sum(SavingsAccount.balance)]).\\
-                    where(SavingsAccount.user_id==cls.id).\\
-                    label('total_balance')
-
-The above recipe will give us the ``balance`` column which renders
-a correlated SELECT::
-
-    >>> print s.query(User).filter(User.balance > 400)
-    SELECT "user".id AS user_id, "user".name AS user_name
-    FROM "user"
-    WHERE (SELECT sum(account.balance) AS sum_1
-    FROM account
-    WHERE account.user_id = "user".id) > :param_1
-
-.. _hybrid_custom_comparators:
-
-Building Custom Comparators
----------------------------
-
-The hybrid property also includes a helper that allows construction of
-custom comparators. A comparator object allows one to customize the
-behavior of each SQLAlchemy expression operator individually.  They
-are useful when creating custom types that have some highly
-idiosyncratic behavior on the SQL side.
-
-The example class below allows case-insensitive comparisons on the attribute
-named ``word_insensitive``::
-
-    from sqlalchemy.ext.hybrid import Comparator, hybrid_property
-    from sqlalchemy import func, Column, Integer, String
-    from sqlalchemy.orm import Session
-    from sqlalchemy.ext.declarative import declarative_base
-
-    Base = declarative_base()
-
-    class CaseInsensitiveComparator(Comparator):
-        def __eq__(self, other):
-            return func.lower(self.__clause_element__()) == func.lower(other)
-
-    class SearchWord(Base):
-        __tablename__ = 'searchword'
-        id = Column(Integer, primary_key=True)
-        word = Column(String(255), nullable=False)
-
-        @hybrid_property
-        def word_insensitive(self):
-            return self.word.lower()
-
-        @word_insensitive.comparator
-        def word_insensitive(cls):
-            return CaseInsensitiveComparator(cls.word)
-
-Above, SQL expressions against ``word_insensitive`` will apply the ``LOWER()``
-SQL function to both sides::
-
-    >>> print Session().query(SearchWord).filter_by(word_insensitive="Trucks")
-    SELECT searchword.id AS searchword_id, searchword.word AS searchword_word
-    FROM searchword
-    WHERE lower(searchword.word) = lower(:lower_1)
-
-The ``CaseInsensitiveComparator`` above implements part of the
-:class:`.ColumnOperators` interface.   A "coercion" operation like
-lowercasing can be applied to all comparison operations (i.e. ``eq``,
-``lt``, ``gt``, etc.) using :meth:`.Operators.operate`::
-
-    class CaseInsensitiveComparator(Comparator):
-        def operate(self, op, other):
-            return op(func.lower(self.__clause_element__()), func.lower(other))
-
-Hybrid Value Objects
---------------------
-
-Note in our previous example, if we were to compare the
-``word_insensitive`` attribute of a ``SearchWord`` instance to a plain
-Python string, the plain Python string would not be coerced to lower
-case - the ``CaseInsensitiveComparator`` we built, being returned by
-``@word_insensitive.comparator``, only applies to the SQL side.
-
-A more comprehensive form of the custom comparator is to construct a
-*Hybrid Value Object*. This technique applies the target value or
-expression to a value object which is then returned by the accessor in
-all cases.   The value object allows control of all operations upon
-the value as well as how compared values are treated, both on the SQL
-expression side as well as the Python value side.   Replacing the
-previous ``CaseInsensitiveComparator`` class with a new
-``CaseInsensitiveWord`` class::
-
-    class CaseInsensitiveWord(Comparator):
-        "Hybrid value representing a lower case representation of a word."
-
-        def __init__(self, word):
-            if isinstance(word, basestring):
-                self.word = word.lower()
-            elif isinstance(word, CaseInsensitiveWord):
-                self.word = word.word
-            else:
-                self.word = func.lower(word)
-
-        def operate(self, op, other):
-            if not isinstance(other, CaseInsensitiveWord):
-                other = CaseInsensitiveWord(other)
-            return op(self.word, other.word)
-
-        def __clause_element__(self):
-            return self.word
-
-        def __str__(self):
-            return self.word
-
-        key = 'word'
-        "Label to apply to Query tuple results"
-
-Above, the ``CaseInsensitiveWord`` object represents ``self.word``,
-which may be a SQL function, or may be a Python native.   By
-overriding ``operate()`` and ``__clause_element__()`` to work in terms
-of ``self.word``, all comparison operations will work against the
-"converted" form of ``word``, whether it be SQL side or Python side.
-Our ``SearchWord`` class can now deliver the ``CaseInsensitiveWord``
-object unconditionally from a single hybrid call::
-
-    class SearchWord(Base):
-        __tablename__ = 'searchword'
-        id = Column(Integer, primary_key=True)
-        word = Column(String(255), nullable=False)
-
-        @hybrid_property
-        def word_insensitive(self):
-            return CaseInsensitiveWord(self.word)
-
-The ``word_insensitive`` attribute now has case-insensitive comparison
-behavior universally, including SQL expression vs. Python expression
-(note the Python value is converted to lower case on the Python side
-here)::
-
-    >>> print Session().query(SearchWord).filter_by(word_insensitive="Trucks")
-    SELECT searchword.id AS searchword_id, searchword.word AS searchword_word
-    FROM searchword
-    WHERE lower(searchword.word) = :lower_1
-
-SQL expression versus SQL expression::
-
-    >>> sw1 = aliased(SearchWord)
-    >>> sw2 = aliased(SearchWord)
-    >>> print Session().query(
-    ...                    sw1.word_insensitive,
-    ...                    sw2.word_insensitive).\\
-    ...                        filter(
-    ...                            sw1.word_insensitive > sw2.word_insensitive
-    ...                        )
-    SELECT lower(searchword_1.word) AS lower_1,
-    lower(searchword_2.word) AS lower_2
-    FROM searchword AS searchword_1, searchword AS searchword_2
-    WHERE lower(searchword_1.word) > lower(searchword_2.word)
-
-Python only expression::
-
-    >>> ws1 = SearchWord(word="SomeWord")
-    >>> ws1.word_insensitive == "sOmEwOrD"
-    True
-    >>> ws1.word_insensitive == "XOmEwOrX"
-    False
-    >>> print ws1.word_insensitive
-    someword
-
-The Hybrid Value pattern is very useful for any kind of value that may
-have multiple representations, such as timestamps, time deltas, units
-of measurement, currencies and encrypted passwords.

-.. _hybrid_transformers:
-
-Building Transformers
-----------------------
-
-A *transformer* is an object which can receive a :class:`.Query`
-object and return a new one.   The :class:`.Query` object includes a
-method :meth:`.with_transformation` that returns a new :class:`.Query`
-transformed by the given function.
-
-We can combine this with the :class:`.Comparator` class to produce one type
-of recipe which can both set up the FROM clause of a query as well as assign
-filtering criterion.
-
-Consider a mapped class ``Node``, which assembles using adjacency list
-into a hierarchical tree pattern::
-
-    from sqlalchemy import Column, Integer, ForeignKey
-    from sqlalchemy.orm import relationship
-    from sqlalchemy.ext.declarative import declarative_base
-    Base = declarative_base()
-
-    class Node(Base):
-        __tablename__ = 'node'
-        id =Column(Integer, primary_key=True)
-        parent_id = Column(Integer, ForeignKey('node.id'))
-        parent = relationship("Node", remote_side=id)
-
-Suppose we wanted to add an accessor ``grandparent``.  This would
-return the ``parent`` of ``Node.parent``.  When we have an instance of
-``Node``, this is simple::
-
-    from sqlalchemy.ext.hybrid import hybrid_property
-
-    class Node(Base):
-        # ...
-
-        @hybrid_property
-        def grandparent(self):
-            return self.parent.parent
-
-For the expression, things are not so clear.   We'd need to construct
-a :class:`.Query` where we :meth:`~.Query.join` twice along
-``Node.parent`` to get to the ``grandparent``.   We can instead return
-a transforming callable that we'll combine with the
-:class:`.Comparator` class to receive any :class:`.Query` object, and
-return a new one that's joined to the ``Node.parent`` attribute and
-filtered based on the given criterion::
-
-    from sqlalchemy.ext.hybrid import Comparator
-
-    class GrandparentTransformer(Comparator):
-        def operate(self, op, other):
-            def transform(q):
-                cls = self.__clause_element__()
-                parent_alias = aliased(cls)
-                return q.join(parent_alias, cls.parent).\\
-                            filter(op(parent_alias.parent, other))
-            return transform
-
-    Base = declarative_base()
-
-    class Node(Base):
-        __tablename__ = 'node'
-        id =Column(Integer, primary_key=True)
-        parent_id = Column(Integer, ForeignKey('node.id'))
-        parent = relationship("Node", remote_side=id)
-
-        @hybrid_property
-        def grandparent(self):
-            return self.parent.parent
-
-        @grandparent.comparator
-        def grandparent(cls):
-            return GrandparentTransformer(cls)
-
-The ``GrandparentTransformer`` overrides the core
-:meth:`.Operators.operate` method at the base of the
-:class:`.Comparator` hierarchy to return a query-transforming
-callable, which then runs the given comparison operation in a
-particular context. Such as, in the example above, the ``operate``
-method is called, given the :attr:`.Operators.eq` callable as well as
-the right side of the comparison ``Node(id=5)``.  A function
-``transform`` is then returned which will transform a :class:`.Query`
-first to join to ``Node.parent``, then to compare ``parent_alias``
-using :attr:`.Operators.eq` against the left and right sides, passing
-into :class:`.Query.filter`:
-
-.. sourcecode:: pycon+sql
-
-    >>> from sqlalchemy.orm import Session
-    >>> session = Session()
-    {sql}>>> session.query(Node).\\
-    ...        with_transformation(Node.grandparent==Node(id=5)).\\
-    ...        all()
-    SELECT node.id AS node_id, node.parent_id AS node_parent_id
-    FROM node JOIN node AS node_1 ON node_1.id = node.parent_id
-    WHERE :param_1 = node_1.parent_id
-    {stop}
-
-We can modify the pattern to be more verbose but flexible by separating
-the "join" step from the "filter" step.  The tricky part here is ensuring
-that successive instances of ``GrandparentTransformer`` use the same
-:class:`.AliasedClass` object against ``Node``.  Below we use a simple
-memoizing approach that associates a ``GrandparentTransformer``
-with each class::
-
-    class Node(Base):
-
-        # ...
-
-        @grandparent.comparator
-        def grandparent(cls):
-            # memoize a GrandparentTransformer
-            # per class
-            if '_gp' not in cls.__dict__:
-                cls._gp = GrandparentTransformer(cls)
-            return cls._gp
-
-    class GrandparentTransformer(Comparator):
-
-        def __init__(self, cls):
-            self.parent_alias = aliased(cls)
-
-        @property
-        def join(self):
-            def go(q):
-                return q.join(self.parent_alias, Node.parent)
-            return go
-
-        def operate(self, op, other):
-            return op(self.parent_alias.parent, other)
-
-.. sourcecode:: pycon+sql
-
-    {sql}>>> session.query(Node).\\
-    ...            with_transformation(Node.grandparent.join).\\
-    ...            filter(Node.grandparent==Node(id=5))
-    SELECT node.id AS node_id, node.parent_id AS node_parent_id
-    FROM node JOIN node AS node_1 ON node_1.id = node.parent_id
-    WHERE :param_1 = node_1.parent_id
-    {stop}
-
-The "transformer" pattern is an experimental pattern that starts
-to make usage of some functional programming paradigms.
-While it's only recommended for advanced and/or patient developers,
-there's probably a whole lot of amazing things it can be used for.

-
-Establishing Mutability on Scalar Column Values
-===============================================
-
-A typical example of a "mutable" structure is a Python dictionary.
-Following the example introduced in :ref:`types_toplevel`, we
-begin with a custom type that marshals Python dictionaries into
-JSON strings before being persisted::
-
-    from sqlalchemy.types import TypeDecorator, VARCHAR
-    import json
-
-    class JSONEncodedDict(TypeDecorator):
-        "Represents an immutable structure as a json-encoded string."
-
-        impl = VARCHAR
-
-        def process_bind_param(self, value, dialect):
-            if value is not None:
-                value = json.dumps(value)
-            return value
-
-        def process_result_value(self, value, dialect):
-            if value is not None:
-                value = json.loads(value)
-            return value
-
-The usage of ``json`` is only for the purposes of example. The
-:mod:`sqlalchemy.ext.mutable` extension can be used
-with any type whose target Python type may be mutable, including
-:class:`.PickleType`, :class:`.postgresql.ARRAY`, etc.
-
-When using the :mod:`sqlalchemy.ext.mutable` extension, the value itself
-tracks all parents which reference it.  Below, we illustrate the a simple
-version of the :class:`.MutableDict` dictionary object, which applies
-the :class:`.Mutable` mixin to a plain Python dictionary::
-
-    from sqlalchemy.ext.mutable import Mutable
-
-    class MutableDict(Mutable, dict):
-        @classmethod
-        def coerce(cls, key, value):
-            "Convert plain dictionaries to MutableDict."
-
-            if not isinstance(value, MutableDict):
-                if isinstance(value, dict):
-                    return MutableDict(value)
-
-                # this call will raise ValueError
-                return Mutable.coerce(key, value)
-            else:
-                return value
-
-        def __setitem__(self, key, value):
-            "Detect dictionary set events and emit change events."
-
-            dict.__setitem__(self, key, value)
-            self.changed()
-

-
-            dict.__delitem__(self, key)
-            self.changed()
-
-The above dictionary class takes the approach of subclassing the Python
-built-in ``dict`` to produce a dict
-subclass which routes all mutation events through ``__setitem__``.  There are
-variants on this approach, such as subclassing ``UserDict.UserDict`` or
-``collections.MutableMapping``; the part that's important to this example is
-that the :meth:`.Mutable.changed` method is called whenever an in-place
-change to the datastructure takes place.
-
-We also redefine the :meth:`.Mutable.coerce` method which will be used to
-convert any values that are not instances of ``MutableDict``, such
-as the plain dictionaries returned by the ``json`` module, into the
-appropriate type.  Defining this method is optional; we could just as well
-created our ``JSONEncodedDict`` such that it always returns an instance
-of ``MutableDict``, and additionally ensured that all calling code
-uses ``MutableDict`` explicitly.  When :meth:`.Mutable.coerce` is not
-overridden, any values applied to a parent object which are not instances
-of the mutable type will raise a ``ValueError``.
-
-Our new ``MutableDict`` type offers a class method
-:meth:`~.Mutable.as_mutable` which we can use within column metadata
-to associate with types. This method grabs the given type object or
-class and associates a listener that will detect all future mappings
-of this type, applying event listening instrumentation to the mapped
-attribute. Such as, with classical table metadata::
-
-    from sqlalchemy import Table, Column, Integer
-
-    my_data = Table('my_data', metadata,
-        Column('id', Integer, primary_key=True),
-        Column('data', MutableDict.as_mutable(JSONEncodedDict))
-    )
-
-Above, :meth:`~.Mutable.as_mutable` returns an instance of ``JSONEncodedDict``
-(if the type object was not an instance already), which will intercept any
-attributes which are mapped against this type.  Below we establish a simple
-mapping against the ``my_data`` table::
-
-    from sqlalchemy import mapper
-
-    class MyDataClass(object):
-        pass
-
-    # associates mutation listeners with MyDataClass.data
-    mapper(MyDataClass, my_data)
-
-The ``MyDataClass.data`` member will now be notified of in place changes
-to its value.
-
-There's no difference in usage when using declarative::
-
-    from sqlalchemy.ext.declarative import declarative_base
-
-    Base = declarative_base()
-
-    class MyDataClass(Base):
-        __tablename__ = 'my_data'
-        id = Column(Integer, primary_key=True)
-        data = Column(MutableDict.as_mutable(JSONEncodedDict))
-
-Any in-place changes to the ``MyDataClass.data`` member
-will flag the attribute as "dirty" on the parent object::
-
-    >>> from sqlalchemy.orm import Session
-
-    >>> sess = Session()
-    >>> m1 = MyDataClass(data={'value1':'foo'})
-    >>> sess.add(m1)
-    >>> sess.commit()
-
-    >>> m1.data['value1'] = 'bar'
-    >>> assert m1 in sess.dirty
-    True
-
-The ``MutableDict`` can be associated with all future instances
-of ``JSONEncodedDict`` in one step, using
-:meth:`~.Mutable.associate_with`.  This is similar to
-:meth:`~.Mutable.as_mutable` except it will intercept all occurrences
-of ``MutableDict`` in all mappings unconditionally, without
-the need to declare it individually::
-
-    MutableDict.associate_with(JSONEncodedDict)
-
-    class MyDataClass(Base):
-        __tablename__ = 'my_data'
-        id = Column(Integer, primary_key=True)
-        data = Column(JSONEncodedDict)
-
-
-Supporting Pickling
---------------------
-
-The key to the :mod:`sqlalchemy.ext.mutable` extension relies upon the
-placement of a ``weakref.WeakKeyDictionary`` upon the value object, which
-stores a mapping of parent mapped objects keyed to the attribute name under
-which they are associated with this value. ``WeakKeyDictionary`` objects are
-not picklable, due to the fact that they contain weakrefs and function
-callbacks. In our case, this is a good thing, since if this dictionary were
-picklable, it could lead to an excessively large pickle size for our value
-objects that are pickled by themselves outside of the context of the parent.
-The developer responsibility here is only to provide a ``__getstate__`` method
-that excludes the :meth:`~MutableBase._parents` collection from the pickle
-stream::
-
-    class MyMutableType(Mutable):
-        def __getstate__(self):
-            d = self.__dict__.copy()
-            d.pop('_parents', None)
-            return d
-
-With our dictionary example, we need to return the contents of the dict itself
-(and also restore them on __setstate__)::
-
-    class MutableDict(Mutable, dict):
-        # ....
-
-        def __getstate__(self):
-            return dict(self)
-
-        def __setstate__(self, state):
-            self.update(state)
-
-In the case that our mutable value object is pickled as it is attached to one
-or more parent objects that are also part of the pickle, the :class:`.Mutable`
-mixin will re-establish the :attr:`.Mutable._parents` collection on each value
-object as the owning parents themselves are unpickled.
-
-.. _mutable_composites:
-
-Establishing Mutability on Composites
-=====================================
-
-Composites are a special ORM feature which allow a single scalar attribute to
-be assigned an object value which represents information "composed" from one
-or more columns from the underlying mapped table. The usual example is that of
-a geometric "point", and is introduced in :ref:`mapper_composite`.
-
-.. versionchanged:: 0.7
-    The internals of :func:`.orm.composite` have been
-    greatly simplified and in-place mutation detection is no longer enabled by
-    default; instead, the user-defined value must detect changes on its own and
-    propagate them to all owning parents. The :mod:`sqlalchemy.ext.mutable`
-    extension provides the helper class :class:`.MutableComposite`, which is a
-    slight variant on the :class:`.Mutable` class.
-
-As is the case with :class:`.Mutable`, the user-defined composite class
-subclasses :class:`.MutableComposite` as a mixin, and detects and delivers
-change events to its parents via the :meth:`.MutableComposite.changed` method.
-In the case of a composite class, the detection is usually via the usage of
-Python descriptors (i.e. ``@property``), or alternatively via the special
-Python method ``__setattr__()``. Below we expand upon the ``Point`` class
-introduced in :ref:`mapper_composite` to subclass :class:`.MutableComposite`
-and to also route attribute set events via ``__setattr__`` to the
-:meth:`.MutableComposite.changed` method::
-
-    from sqlalchemy.ext.mutable import MutableComposite
-
-    class Point(MutableComposite):
-        def __init__(self, x, y):
-            self.x = x
-            self.y = y
-
-        def __setattr__(self, key, value):
-            "Intercept set events"
-
-            # set the attribute
-            object.__setattr__(self, key, value)
-
-            # alert all parents to the change
-            self.changed()
-
-        def __composite_values__(self):
-            return self.x, self.y
-
-        def __eq__(self, other):
-            return isinstance(other, Point) and \\
-                other.x == self.x and \\
-                other.y == self.y
-
-        def __ne__(self, other):
-            return not self.__eq__(other)
-
-The :class:`.MutableComposite` class uses a Python metaclass to automatically
-establish listeners for any usage of :func:`.orm.composite` that specifies our
-``Point`` type. Below, when ``Point`` is mapped to the ``Vertex`` class,
-listeners are established which will route change events from ``Point``
-objects to each of the ``Vertex.start`` and ``Vertex.end`` attributes::
-
-    from sqlalchemy.orm import composite, mapper
-    from sqlalchemy import Table, Column
-
-    vertices = Table('vertices', metadata,
-        Column('id', Integer, primary_key=True),
-        Column('x1', Integer),
-        Column('y1', Integer),
-        Column('x2', Integer),
-        Column('y2', Integer),
-        )
-
-    class Vertex(object):
-        pass
-
-    mapper(Vertex, vertices, properties={
-        'start': composite(Point, vertices.c.x1, vertices.c.y1),
-        'end': composite(Point, vertices.c.x2, vertices.c.y2)
-    })
-
-Any in-place changes to the ``Vertex.start`` or ``Vertex.end`` members
-will flag the attribute as "dirty" on the parent object::
-
-    >>> from sqlalchemy.orm import Session
-
-    >>> sess = Session()
-    >>> v1 = Vertex(start=Point(3, 4), end=Point(12, 15))
-    >>> sess.add(v1)
-    >>> sess.commit()
-
-    >>> v1.end.x = 8
-    >>> assert v1 in sess.dirty
-    True
-
-Coercing Mutable Composites
----------------------------
-
-The :meth:`.MutableBase.coerce` method is also supported on composite types.
-In the case of :class:`.MutableComposite`, the :meth:`.MutableBase.coerce`
-method is only called for attribute set operations, not load operations.
-Overriding the :meth:`.MutableBase.coerce` method is essentially equivalent
-to using a :func:`.validates` validation routine for all attributes which
-make use of the custom composite type::
-
-    class Point(MutableComposite):
-        # other Point methods
-        # ...
-
-        def coerce(cls, key, value):
-            if isinstance(value, tuple):
-                value = Point(*value)
-            elif not isinstance(value, Point):
-                raise ValueError("tuple or Point expected")
-            return value
-
-.. versionadded:: 0.7.10,0.8.0b2
-    Support for the :meth:`.MutableBase.coerce` method in conjunction with
-    objects of type :class:`.MutableComposite`.
-
-Supporting Pickling
---------------------
-
-As is the case with :class:`.Mutable`, the :class:`.MutableComposite` helper
-class uses a ``weakref.WeakKeyDictionary`` available via the
-:meth:`MutableBase._parents` attribute which isn't picklable. If we need to
-pickle instances of ``Point`` or its owning class ``Vertex``, we at least need
-to define a ``__getstate__`` that doesn't include the ``_parents`` dictionary.
-Below we define both a ``__getstate__`` and a ``__setstate__`` that package up
-the minimal form of our ``Point`` class::
-
-    class Point(MutableComposite):
-        # ...
-
-        def __getstate__(self):
-            return self.x, self.y
-
-        def __setstate__(self, state):
-            self.x, self.y = state
-
-As with :class:`.Mutable`, the :class:`.MutableComposite` augments the
-pickling process of the parent's object-relational state so that the
-:meth:`MutableBase._parents` collection is restored to all ``Point`` objects.

-"""A custom list that manages index/position information for contained
-elements.
-
-:author: Jason Kirtland
-
-``orderinglist`` is a helper for mutable ordered relationships.  It will
-intercept list operations performed on a :func:`.relationship`-managed
-collection and
-automatically synchronize changes in list position onto a target scalar
-attribute.
-
-Example: A ``slide`` table, where each row refers to zero or more entries
-in a related ``bullet`` table.   The bullets within a slide are
-displayed in order based on the value of the ``position`` column in the
-``bullet`` table.   As entries are reordered in memory, the value of the
-``position`` attribute should be updated to reflect the new sort order::
-
-
-    Base = declarative_base()
-
-    class Slide(Base):
-        __tablename__ = 'slide'
-
-        id = Column(Integer, primary_key=True)
-        name = Column(String)
-
-        bullets = relationship("Bullet", order_by="Bullet.position")
-
-    class Bullet(Base):
-        __tablename__ = 'bullet'
-        id = Column(Integer, primary_key=True)
-        slide_id = Column(Integer, ForeignKey('slide.id'))
-        position = Column(Integer)
-        text = Column(String)
-
-The standard relationship mapping will produce a list-like attribute on each
-``Slide`` containing all related ``Bullet`` objects,
-but coping with changes in ordering is not handled automatically.
-When appending a ``Bullet`` into ``Slide.bullets``, the ``Bullet.position``
-attribute will remain unset until manually assigned.   When the ``Bullet``
-is inserted into the middle of the list, the following ``Bullet`` objects
-will also need to be renumbered.
-
-The :class:`.OrderingList` object automates this task, managing the
-``position`` attribute on all ``Bullet`` objects in the collection.  It is
-constructed using the :func:`.ordering_list` factory::
-
-    from sqlalchemy.ext.orderinglist import ordering_list
-
-    Base = declarative_base()
-
-    class Slide(Base):
-        __tablename__ = 'slide'
-
-        id = Column(Integer, primary_key=True)
-        name = Column(String)
-
-        bullets = relationship("Bullet", order_by="Bullet.position",
-                                collection_class=ordering_list('position'))
-
-    class Bullet(Base):
-        __tablename__ = 'bullet'
-        id = Column(Integer, primary_key=True)
-        slide_id = Column(Integer, ForeignKey('slide.id'))
-        position = Column(Integer)
-        text = Column(String)
-
-With the above mapping the ``Bullet.position`` attribute is managed::
-
-    s = Slide()
-    s.bullets.append(Bullet())
-    s.bullets.append(Bullet())
-    s.bullets[1].position
-    >>> 1
-    s.bullets.insert(1, Bullet())
-    s.bullets[2].position
-    >>> 2
-
-The :class:`.OrderingList` construct only works with **changes** to a collection,
-and not the initial load from the database, and requires that the list be
-sorted when loaded.  Therefore, be sure to
-specify ``order_by`` on the :func:`.relationship` against the target ordering
-attribute, so that the ordering is correct when first loaded.
-
-.. warning::
-
-  :class:`.OrderingList` only provides limited functionality when a primary
-  key column or unique column is the target of the sort.  Operations
-  that are unsupported or are problematic include:
-
-    * two entries must trade values.  This is not supported directly in the
-      case of a primary key or unique constraint because it means at least
-      one row would need to be temporarily removed first, or changed to
-      a third, neutral value while the switch occurs.
-
-    * an entry must be deleted in order to make room for a new entry.
-      SQLAlchemy's unit of work performs all INSERTs before DELETEs within a
-      single flush.  In the case of a primary key, it will trade
-      an INSERT/DELETE of the same primary key for an UPDATE statement in order
-      to lessen the impact of this lmitation, however this does not take place
-      for a UNIQUE column.
-      A future feature will allow the "DELETE before INSERT" behavior to be
-      possible, allevating this limitation, though this feature will require
-      explicit configuration at the mapper level for sets of columns that
-      are to be handled in this way.
-
-:func:`.ordering_list` takes the name of the related object's ordering attribute as
-an argument.  By default, the zero-based integer index of the object's
-position in the :func:`.ordering_list` is synchronized with the ordering attribute:
-index 0 will get position 0, index 1 position 1, etc.  To start numbering at 1
-or some other integer, provide ``count_from=1``.

-          An ``ordering_func`` is called with two positional parameters: the

-
-          If omitted, Python list indexes are used for the attribute values.
-          Two basic pre-built numbering functions are provided in this module:
-          ``count_from_0`` and ``count_from_1``.  For more exotic examples

-          variety of dangerous unexpected database writes.
-
-          SQLAlchemy will add instances to the list via append() when your
-          object loads.  If for some reason the result set from the database
-          skips a step in the ordering (say, row '1' is missing but you get

-          passing, all of the sessions would try to "clean up" the numbering
-          in their commits, possibly causing all but one to fail with a
-          concurrent modification error.
-
-          Recommend leaving this with the default of False, and just call
-          ``reorder()`` if you're doing ``append()`` operations with

-"""Serializer/Deserializer objects for usage with SQLAlchemy query structures,
-allowing "contextual" deserialization.
-
-Any SQLAlchemy query structure, either based on sqlalchemy.sql.*
-or sqlalchemy.orm.* can be used.  The mappers, Tables, Columns, Session
-etc. which are referenced by the structure are not persisted in serialized
-form, but are instead re-associated with the query structure
-when it is deserialized.
-
-Usage is nearly the same as that of the standard Python pickle module::
-
-    from sqlalchemy.ext.serializer import loads, dumps
-    metadata = MetaData(bind=some_engine)
-    Session = scoped_session(sessionmaker())
-
-    # ... define mappers
-
-    query = Session.query(MyClass).filter(MyClass.somedata=='foo').order_by(MyClass.sortkey)
-
-    # pickle the query
-    serialized = dumps(query)
-
-    # unpickle.  Pass in metadata + scoped_session
-    query2 = loads(serialized, metadata, Session)
-
-    print query2.all()
-
-Similar restrictions as when using raw pickle apply; mapped classes must be
-themselves be pickleable, meaning they are importable from a module-level
-namespace.
-
-The serializer module is only appropriate for query structures.  It is not
-needed for:
-
-* instances of user-defined classes.   These contain no references to engines,
-  sessions or expression constructs in the typical case and can be serialized
-  directly.
-
-* Table metadata that is to be loaded entirely from the serialized structure
-  (i.e. is not already declared in the application).   Regular
-  pickle.loads()/dumps() can be used to fully dump any ``MetaData`` object,
-  typically one which was reflected from an existing database at some previous
-  point in time.  The serializer module is specifically for the opposite case,
-  where the Table metadata is already present in memory.

-"""The inspection module provides the :func:`.inspect` function,
-which delivers runtime information about a wide variety
-of SQLAlchemy objects, both within the Core as well as the
-ORM.
-
-The :func:`.inspect` function is the entry point to SQLAlchemy's
-public API for viewing the configuration and construction
-of in-memory objects.   Depending on the type of object
-passed to :func:`.inspect`, the return value will either be
-a related object which provides a known interface, or in many
-cases it will return the object itself.
-
-The rationale for :func:`.inspect` is twofold.  One is that
-it replaces the need to be aware of a large variety of "information
-getting" functions in SQLAlchemy, such as :meth:`.Inspector.from_engine`,
-:func:`.orm.attributes.instance_state`, :func:`.orm.class_mapper`,
-and others.    The other is that the return value of :func:`.inspect`
-is guaranteed to obey a documented API, thus allowing third party
-tools which build on top of SQLAlchemy configurations to be constructed
-in a forwards-compatible way.
-
-.. versionadded:: 0.8 The :func:`.inspect` system is introduced
-   as of version 0.8.

-
-    All of the standard connection :class:`~sqlalchemy.pool.Pool` types can
-    accept event listeners for key connection lifecycle events:
-    creation, pool check-out and check-in.  There are no events fired
-    when a connection closes.
-
-    For any given DB-API connection, there will be one ``connect``
-    event, `n` number of ``checkout`` events, and either `n` or `n - 1`
-    ``checkin`` events.  (If a ``Connection`` is detached from its
-    pool via the ``detach()`` method, it won't be checked back in.)
-
-    These are low-level events for low-level objects: raw Python
-    DB-API connections, without the conveniences of the SQLAlchemy
-    ``Connection`` wrapper, ``Dialect`` services or ``ClauseElement``
-    execution.  If you execute SQL through the connection, explicitly
-    closing all cursors and other resources is recommended.
-
-    Events also receive a ``_ConnectionRecord``, a long-lived internal
-    ``Pool`` object that basically represents a "slot" in the
-    connection pool.  ``_ConnectionRecord`` objects have one public
-    attribute of note: ``info``, a dictionary whose contents are
-    scoped to the lifetime of the DB-API connection managed by the
-    record.  You can use this shared storage area however you like.
-
-    There is no need to subclass ``PoolListener`` to handle events.
-    Any class that implements one or more of these methods can be used
-    as a pool listener.  The ``Pool`` will inspect the methods
-    provided by a listener object and add the listener to one or more
-    internal event queues based on its capabilities.  In terms of
-    efficiency and function call overhead, you're much better off only
-    providing implementations for the hooks you'll be using.

-"""Support for collections of mapped entities.
-
-The collections package supplies the machinery used to inform the ORM of
-collection membership changes.  An instrumentation via decoration approach is
-used, allowing arbitrary types (including built-ins) to be used as entity
-collections without requiring inheritance from a base class.
-
-Instrumentation decoration relays membership change events to the
-:class:`.CollectionAttributeImpl` that is currently managing the collection.
-The decorators observe function call arguments and return values, tracking
-entities entering or leaving the collection.  Two decorator approaches are
-provided.  One is a bundle of generic decorators that map function arguments
-and return values to events::
-
-  from sqlalchemy.orm.collections import collection
-  class MyClass(object):
-      # ...
-
-      @collection.adds(1)
-      def store(self, item):
-          self.data.append(item)
-
-      @collection.removes_return()
-      def pop(self):
-          return self.data.pop()
-
-
-The second approach is a bundle of targeted decorators that wrap appropriate
-append and remove notifiers around the mutation methods present in the
-standard Python ``list``, ``set`` and ``dict`` interfaces.  These could be
-specified in terms of generic decorator recipes, but are instead hand-tooled
-for increased efficiency.  The targeted decorators occasionally implement
-adapter-like behavior, such as mapping bulk-set methods (``extend``,
-``update``, ``__setslice__``, etc.) into the series of atomic mutation events
-that the ORM requires.
-
-The targeted decorators are used internally for automatic instrumentation of
-entity collection classes.  Every collection class goes through a
-transformation process roughly like so:
-
-1. If the class is a built-in, substitute a trivial sub-class
-2. Is this class already instrumented?
-3. Add in generic decorators
-4. Sniff out the collection interface through duck-typing
-5. Add targeted decoration to any undecorated interface method
-
-This process modifies the class at runtime, decorating methods and adding some
-bookkeeping properties.  This isn't possible (or desirable) for built-in
-classes like ``list``, so trivial sub-classes are substituted to hold
-decoration::
-
-  class InstrumentedList(list):
-      pass
-
-Collection classes can be specified in ``relationship(collection_class=)`` as
-types or a function that returns an instance.  Collection classes are
-inspected and instrumented during the mapper compilation phase.  The
-collection_class callable will be executed once to produce a specimen
-instance, and the type of that specimen will be instrumented.  Functions that
-return built-in types like ``lists`` will be adapted to produce instrumented
-instances.
-
-When extending a known type like ``list``, additional decorations are not
-generally not needed.  Odds are, the extension method will delegate to a
-method that's already instrumented.  For example::
-
-  class QueueIsh(list):
-     def push(self, item):
-         self.append(item)
-     def shift(self):
-         return self.pop(0)
-
-There's no need to decorate these methods.  ``append`` and ``pop`` are already
-instrumented as part of the ``list`` interface.  Decorating them would fire
-duplicate events, which should be avoided.
-
-The targeted decoration tries not to rely on other methods in the underlying
-collection class, but some are unavoidable.  Many depend on 'read' methods
-being present to properly instrument a 'write', for example, ``__setitem__``
-needs ``__getitem__``.  "Bulk" methods like ``update`` and ``extend`` may also
-reimplemented in terms of atomic appends and removes, so the ``extend``
-decoration will actually perform many ``append`` operations and not call the
-underlying method at all.
-
-Tight control over bulk operation and the firing of events is also possible by
-implementing the instrumentation internally in your methods.  The basic
-instrumentation package works under the general assumption that collection
-mutation will not raise unusual exceptions.  If you want to closely
-orchestrate append and remove events with exception management, internal
-instrumentation may be the answer.  Within your method,
-``collection_adapter(self)`` will retrieve an object that you can use for
-explicit control over triggering append and remove events.
-
-The owning object and :class:`.CollectionAttributeImpl` are also reachable
-through the adapter, allowing for some very sophisticated behavior.

-class MapperExtension(object):
-    """Base implementation for :class:`.Mapper` event hooks.
-
-    .. note::
-
-       :class:`.MapperExtension` is deprecated.   Please
-       refer to :func:`.event.listen` as well as
-       :class:`.MapperEvents`.
-
-    New extension classes subclass :class:`.MapperExtension` and are specified
-    using the ``extension`` mapper() argument, which is a single
-    :class:`.MapperExtension` or a list of such::
-
-        from sqlalchemy.orm.interfaces import MapperExtension
-
-        class MyExtension(MapperExtension):
-            def before_insert(self, mapper, connection, instance):
-                print "instance %s before insert !" % instance
-
-        m = mapper(User, users_table, extension=MyExtension())
-
-    A single mapper can maintain a chain of ``MapperExtension``
-    objects. When a particular mapping event occurs, the
-    corresponding method on each ``MapperExtension`` is invoked
-    serially, and each method has the ability to halt the chain
-    from proceeding further::
-
-        m = mapper(User, users_table, extension=[ext1, ext2, ext3])
-
-    Each ``MapperExtension`` method returns the symbol
-    EXT_CONTINUE by default.   This symbol generally means "move
-    to the next ``MapperExtension`` for processing".  For methods
-    that return objects like translated rows or new object
-    instances, EXT_CONTINUE means the result of the method
-    should be ignored.   In some cases it's required for a
-    default mapper activity to be performed, such as adding a
-    new instance to a result list.
-
-    The symbol EXT_STOP has significance within a chain
-    of ``MapperExtension`` objects that the chain will be stopped
-    when this symbol is returned.  Like EXT_CONTINUE, it also
-    has additional significance in some cases that a default
-    mapper activity will not be performed.

-        In the example below we redefine :meth:`.PropComparator.operate`
-        to wrap both sides of an expression in ``func.lower()`` to produce
-        case-insensitive comparison::
-
-            from sqlalchemy.orm import comparable_property
-            from sqlalchemy.orm.interfaces import PropComparator
-            from sqlalchemy.sql import func
-            from sqlalchemy import Integer, String, Column
-            from sqlalchemy.ext.declarative import declarative_base
-
-            class CaseInsensitiveComparator(PropComparator):
-                def __clause_element__(self):
-                    return self.prop
-
-                def operate(self, op, other):
-                    return op(
-                        func.lower(self.__clause_element__()),
-                        func.lower(other)
-                    )
-
-            Base = declarative_base()
-
-            class SearchWord(Base):
-                __tablename__ = 'search_word'
-                id = Column(Integer, primary_key=True)
-                word = Column(String)
-                word_insensitive = comparable_property(lambda prop, mapper:
-                                CaseInsensitiveComparator(mapper.c.word, mapper)
-                            )
-
-
-        A mapping like the above allows the ``word_insensitive`` attribute
-        to render an expression like::
-
-            >>> print SearchWord.word_insensitive == "Trucks"
-            lower(search_word.word) = lower(:lower_1)
-
-        :param comparator_factory:
-          A PropComparator subclass or factory that defines operator behavior
-          for this property.
-
-        :param descriptor:
-          Optional when used in a ``properties={}`` declaration.  The Python
-          descriptor or property to layer comparison behavior on top of.
-
-          The like-named descriptor will be automatically retrieved from the
-          mapped class if left blank in a ``properties`` declaration.
-
-        """
-        self.descriptor = descriptor
-        self.comparator_factory = comparator_factory
-        self.doc = doc or (descriptor and descriptor.__doc__) or None
-        util.set_creation_order(self)
-
-    def _comparator_factory(self, mapper):
-        return self.comparator_factory(self, mapper)

-"""Defines SQLAlchemy's system of class instrumentation.
-
-This module is usually not directly visible to user applications, but
-defines a large part of the ORM's interactivity.
-
-instrumentation.py deals with registration of end-user classes
-for state tracking.   It interacts closely with state.py
-and attributes.py which establish per-instance and per-class-attribute
-instrumentation, respectively.
-
-The class instrumentation system can be customized on a per-class
-or global basis using the :mod:`sqlalchemy.ext.instrumentation`
-module, which provides the means to build and specify
-alternate instrumentation forms.
-
-.. versionchanged: 0.8
-   The instrumentation extension system was moved out of the
-   ORM and into the external :mod:`sqlalchemy.ext.instrumentation`
-   package.  When that package is imported, it installs
-   itself within sqlalchemy.orm so that its more comprehensive
-   resolution mechanics take effect.

-    built-in Python comparison and math operator methods, such as
-    :meth:`.operators.ColumnOperators.__eq__`,
-    :meth:`.operators.ColumnOperators.__lt__`, and
-    :meth:`.operators.ColumnOperators.__add__`, can be overridden to provide
-    new operator behavior. The custom :class:`.PropComparator` is passed to
-    the :class:`.MapperProperty` instance via the ``comparator_factory``
-    argument. In each case,
-    the appropriate subclass of :class:`.PropComparator` should be used::

-        This function is typically used behind the scenes

-        many of the usual :func:`.mapper` arguments are handled
-        by the Declarative extension itself, including ``class_``,
-        ``local_table``, ``properties``, and  ``inherits``.
-        Other options are passed to :func:`.mapper` using
-        the ``__mapper_args__`` class variable::
-
-           class MyClass(Base):

-               id = Column(Integer, primary_key=True)

-
-        Explicit use of :func:`.mapper`
-        is often referred to as *classical mapping*.  The above

-
-            :ref:`classical_mapping` - discussion of direct usage of
-            :func:`.mapper`
-
-        :param class\_: The class to be mapped.  When using Declarative,
-          this argument is automatically passed as the declared class
-          itself.
-
-        :param local_table: The :class:`.Table` or other selectable
-           to which the class is mapped.  May be ``None`` if
-           this mapper inherits from another mapper using single-table
-           inheritance.   When using Declarative, this argument is
-           automatically passed by the extension, based on what
-           is configured via the ``__table__`` argument or via the
-           :class:`.Table` produced as a result of the ``__tablename__``
-           and :class:`.Column` arguments present.
-
-        :param always_refresh: If True, all query operations for this mapped
-           class will overwrite all data within object instances that already
-           exist within the session, erasing any in-memory changes with
-           whatever information was loaded from the database. Usage of this
-           flag is highly discouraged; as an alternative, see the method
-           :meth:`.Query.populate_existing`.
-
-        :param allow_partial_pks: Defaults to True.  Indicates that a
-           composite primary key with some NULL values should be considered as
-           possibly existing within the database. This affects whether a
-           mapper will assign an incoming row to an existing identity, as well
-           as if :meth:`.Session.merge` will check the database first for a
-           particular primary key value. A "partial primary key" can occur if
-           one has mapped to an OUTER JOIN, for example.
-
-        :param batch: Defaults to ``True``, indicating that save operations
-           of multiple entities can be batched together for efficiency.
-           Setting to False indicates
-           that an instance will be fully saved before saving the next
-           instance.  This is used in the extremely rare case that a
-           :class:`.MapperEvents` listener requires being called
-           in between individual row persistence operations.
-
-        :param column_prefix: A string which will be prepended
-           to the mapped attribute name when :class:`.Column`
-           objects are automatically assigned as attributes to the
-           mapped class.  Does not affect explicitly specified
-           column-based properties.
-
-           See the section :ref:`column_prefix` for an example.
-
-        :param concrete: If True, indicates this mapper should use concrete
-           table inheritance with its parent mapper.
-
-           See the section :ref:`concrete_inheritance` for an example.
-
-        :param confirm_deleted_rows: defaults to True; when a DELETE occurs
-          of one more more rows based on specific primary keys, a warning is
-          emitted when the number of rows matched does not equal the number
-          of rows expected.  This parameter may be set to False to handle the case
-          where database ON DELETE CASCADE rules may be deleting some of those
-          rows automatically.  The warning may be changed to an exception
-          in a future release.
-
-          .. versionadded:: 0.9.4 - added :paramref:`.mapper.confirm_deleted_rows`
-             as well as conditional matched row checking on delete.
-
-        :param eager_defaults: if True, the ORM will immediately fetch the
-          value of server-generated default values after an INSERT or UPDATE,
-          rather than leaving them as expired to be fetched on next access.
-          This can be used for event schemes where the server-generated values
-          are needed immediately before the flush completes.   By default,
-          this scheme will emit an individual ``SELECT`` statement per row
-          inserted or updated, which note can add significant performance
-          overhead.  However, if the
-          target database supports :term:`RETURNING`, the default values will be
-          returned inline with the INSERT or UPDATE statement, which can
-          greatly enhance performance for an application that needs frequent
-          access to just-generated server defaults.
-
-          .. versionchanged:: 0.9.0 The ``eager_defaults`` option can now
-             make use of :term:`RETURNING` for backends which support it.
-
-        :param exclude_properties: A list or set of string column names to
-          be excluded from mapping.
-
-          See :ref:`include_exclude_cols` for an example.
-
-        :param extension: A :class:`.MapperExtension` instance or
-           list of :class:`.MapperExtension` instances which will be applied
-           to all operations by this :class:`.Mapper`.  **Deprecated.**
-           Please see :class:`.MapperEvents`.
-
-        :param include_properties: An inclusive list or set of string column
-          names to map.
-
-          See :ref:`include_exclude_cols` for an example.
-
-        :param inherits: A mapped class or the corresponding :class:`.Mapper`
-          of one indicating a superclass to which this :class:`.Mapper`
-          should *inherit* from.   The mapped class here must be a subclass
-          of the other mapper's class.   When using Declarative, this argument
-          is passed automatically as a result of the natural class
-          hierarchy of the declared classes.
-
-          .. seealso::
-
-            :ref:`inheritance_toplevel`
-
-        :param inherit_condition: For joined table inheritance, a SQL
-           expression which will
-           define how the two tables are joined; defaults to a natural join
-           between the two tables.
-
-        :param inherit_foreign_keys: When ``inherit_condition`` is used and the
-           columns present are missing a :class:`.ForeignKey` configuration,
-           this parameter can be used to specify which columns are "foreign".
-           In most cases can be left as ``None``.
-
-        :param legacy_is_orphan: Boolean, defaults to ``False``.
-          When ``True``, specifies that "legacy" orphan consideration
-          is to be applied to objects mapped by this mapper, which means
-          that a pending (that is, not persistent) object is auto-expunged
-          from an owning :class:`.Session` only when it is de-associated
-          from *all* parents that specify a ``delete-orphan`` cascade towards
-          this mapper.  The new default behavior is that the object is auto-expunged
-          when it is de-associated with *any* of its parents that specify
-          ``delete-orphan`` cascade.  This behavior is more consistent with
-          that of a persistent object, and allows behavior to be consistent
-          in more scenarios independently of whether or not an orphanable
-          object has been flushed yet or not.
-
-          See the change note and example at :ref:`legacy_is_orphan_addition`
-          for more detail on this change.
-
-          .. versionadded:: 0.8 - the consideration of a pending object as
-            an "orphan" has been modified to more closely match the
-            behavior as that of persistent objects, which is that the object
-            is expunged from the :class:`.Session` as soon as it is
-            de-associated from any of its orphan-enabled parents.  Previously,
-            the pending object would be expunged only if de-associated
-            from all of its orphan-enabled parents. The new flag ``legacy_is_orphan``
-            is added to :func:`.orm.mapper` which re-establishes the
-            legacy behavior.
-
-        :param non_primary: Specify that this :class:`.Mapper` is in addition
-          to the "primary" mapper, that is, the one used for persistence.
-          The :class:`.Mapper` created here may be used for ad-hoc
-          mapping of the class to an alternate selectable, for loading
-          only.
-
-          :paramref:`.Mapper.non_primary` is not an often used option, but
-          is useful in some specific :func:`.relationship` cases.
-
-          .. seealso::
-
-              :ref:`relationship_non_primary_mapper`
-
-        :param order_by: A single :class:`.Column` or list of :class:`.Column`
-           objects for which selection operations should use as the default
-           ordering for entities.  By default mappers have no pre-defined
-           ordering.
-
-        :param passive_updates: Indicates UPDATE behavior of foreign key
-           columns when a primary key column changes on a joined-table
-           inheritance mapping.   Defaults to ``True``.
-
-           When True, it is assumed that ON UPDATE CASCADE is configured on
-           the foreign key in the database, and that the database will handle
-           propagation of an UPDATE from a source column to dependent columns
-           on joined-table rows.
-
-           When False, it is assumed that the database does not enforce
-           referential integrity and will not be issuing its own CASCADE
-           operation for an update.  The unit of work process will
-           emit an UPDATE statement for the dependent columns during a
-           primary key change.
-
-           .. seealso::
-
-               :ref:`passive_updates` - description of a similar feature as
-               used with :func:`.relationship`
-
-        :param polymorphic_on: Specifies the column, attribute, or
-          SQL expression used to determine the target class for an
-          incoming row, when inheriting classes are present.
-
-          This value is commonly a :class:`.Column` object that's
-          present in the mapped :class:`.Table`::
-
-            class Employee(Base):
-                __tablename__ = 'employee'
-
-                id = Column(Integer, primary_key=True)
-                discriminator = Column(String(50))
-
-                __mapper_args__ = {
-                    "polymorphic_on":discriminator,
-                    "polymorphic_identity":"employee"
-                }
-
-          It may also be specified
-          as a SQL expression, as in this example where we
-          use the :func:`.case` construct to provide a conditional
-          approach::
-
-            class Employee(Base):
-                __tablename__ = 'employee'
-
-                id = Column(Integer, primary_key=True)
-                discriminator = Column(String(50))
-
-                __mapper_args__ = {
-                    "polymorphic_on":case([
-                        (discriminator == "EN", "engineer"),
-                        (discriminator == "MA", "manager"),
-                    ], else_="employee"),
-                    "polymorphic_identity":"employee"
-                }
-
-          It may also refer to any attribute
-          configured with :func:`.column_property`, or to the
-          string name of one::
-
-                class Employee(Base):
-                    __tablename__ = 'employee'

-              ``polymorphic_on`` may be specified as a SQL expression,
-              or refer to any attribute configured with
-              :func:`.column_property`, or to the string name of one.
-
-          When setting ``polymorphic_on`` to reference an
-          attribute or expression that's not present in the
-          locally mapped :class:`.Table`, yet the value
-          of the discriminator should be persisted to the database,
-          the value of the
-          discriminator is not automatically set on new
-          instances; this must be handled by the user,
-          either through manual means or via event listeners.
-          A typical approach to establishing such a listener
-          looks like::
-
-                from sqlalchemy import event
-                from sqlalchemy.orm import object_mapper
-
-                @event.listens_for(Employee, "init", propagate=True)
-                def set_identity(instance, *arg, **kw):
-                    mapper = object_mapper(instance)
-                    instance.discriminator = mapper.polymorphic_identity
-
-          Where above, we assign the value of ``polymorphic_identity``
-          for the mapped class to the ``discriminator`` attribute,
-          thus persisting the value to the ``discriminator`` column
-          in the database.
-
-          .. seealso::
-
-            :ref:`inheritance_toplevel`
-
-        :param polymorphic_identity: Specifies the value which
-          identifies this particular class as returned by the
-          column expression referred to by the ``polymorphic_on``
-          setting.  As rows are received, the value corresponding
-          to the ``polymorphic_on`` column expression is compared
-          to this value, indicating which subclass should
-          be used for the newly reconstructed object.
-
-        :param properties: A dictionary mapping the string names of object
-           attributes to :class:`.MapperProperty` instances, which define the
-           persistence behavior of that attribute.  Note that :class:`.Column`
-           objects present in
-           the mapped :class:`.Table` are automatically placed into
-           ``ColumnProperty`` instances upon mapping, unless overridden.
-           When using Declarative, this argument is passed automatically,
-           based on all those :class:`.MapperProperty` instances declared
-           in the declared class body.
-
-        :param primary_key: A list of :class:`.Column` objects which define the
-           primary key to be used against this mapper's selectable unit.
-           This is normally simply the primary key of the ``local_table``, but
-           can be overridden here.
-
-        :param version_id_col: A :class:`.Column`
-           that will be used to keep a running version id of rows
-           in the table.  This is used to detect concurrent updates or
-           the presence of stale data in a flush.  The methodology is to
-           detect if an UPDATE statement does not match the last known
-           version id, a
-           :class:`~sqlalchemy.orm.exc.StaleDataError` exception is
-           thrown.
-           By default, the column must be of :class:`.Integer` type,
-           unless ``version_id_generator`` specifies an alternative version
-           generator.

-

-          be generated.  Defaults to ``None``, which indicates that
-          a simple integer counting scheme be employed.  To provide a custom
-          versioning scheme, provide a callable function of the form::
-
-              def generate_version(version):
-                  return next_version
-
-          Alternatively, server-side versioning functions such as triggers,
-          or programmatic versioning schemes outside of the version id generator
-          may be used, by specifying the value ``False``.
-          Please see :ref:`server_side_version_counter` for a discussion

-        Use this function when the given column is not directly present within the

-        scalar SELECT queries.
-
-        Columns that aren't present in the mapper's selectable won't be persisted

-
-        :param deferred:

-              it does not load immediately, and is instead loaded when the

-            to a SQL expression (and not a single table-bound column)
-            is considered to be a "read only" property; populating it
-            has no effect on the state of data, and it can only return
-            database state.   For this reason a column_property()'s value
-            is expired whenever the parent object is involved in a
-            flush, that is, has any kind of "dirty" state within a flush.
-            Setting this parameter to ``False`` will have the effect of
-            leaving any existing value present after the flush proceeds.
-            Note however that the :class:`.Session` with default expiration
-            settings still expires
-            all attributes after a :meth:`.Session.commit` call, however.

-
-        **Simple Relationship Joins**
-
-        Consider a mapping between two classes ``User`` and ``Address``,
-        with a relationship ``User.addresses`` representing a collection
-        of ``Address`` objects associated with each ``User``.   The most common
-        usage of :meth:`~.Query.join` is to create a JOIN along this
-        relationship, using the ``User.addresses`` attribute as an indicator
-        for how this should occur::
-
-            q = session.query(User).join(User.addresses)
-
-        Where above, the call to :meth:`~.Query.join` along ``User.addresses``
-        will result in SQL equivalent to::
-
-            SELECT user.* FROM user JOIN address ON user.id = address.user_id
-
-        In the above example we refer to ``User.addresses`` as passed to
-        :meth:`~.Query.join` as the *on clause*, that is, it indicates
-        how the "ON" portion of the JOIN should be constructed.  For a
-        single-entity query such as the one above (i.e. we start by selecting
-        only from ``User`` and nothing else), the relationship can also be
-        specified by its string name::
-
-            q = session.query(User).join("addresses")
-
-        :meth:`~.Query.join` can also accommodate multiple
-        "on clause" arguments to produce a chain of joins, such as below
-        where a join across four related entities is constructed::
-
-            q = session.query(User).join("orders", "items", "keywords")
-
-        The above would be shorthand for three separate calls to
-        :meth:`~.Query.join`, each using an explicit attribute to indicate
-        the source entity::
-
-            q = session.query(User).\\
-                    join(User.orders).\\
-                    join(Order.items).\\
-                    join(Item.keywords)
-
-        **Joins to a Target Entity or Selectable**
-
-        A second form of :meth:`~.Query.join` allows any mapped entity
-        or core selectable construct as a target.   In this usage,
-        :meth:`~.Query.join` will attempt
-        to create a JOIN along the natural foreign key relationship between
-        two entities::
-
-            q = session.query(User).join(Address)
-
-        The above calling form of :meth:`~.Query.join` will raise an error if
-        either there are no foreign keys between the two entities, or if
-        there are multiple foreign key linkages between them.   In the
-        above calling form, :meth:`~.Query.join` is called upon to
-        create the "on clause" automatically for us.  The target can
-        be any mapped entity or selectable, such as a :class:`.Table`::
-
-            q = session.query(User).join(addresses_table)
-
-        **Joins to a Target with an ON Clause**
-
-        The third calling form allows both the target entity as well
-        as the ON clause to be passed explicitly.   Suppose for
-        example we wanted to join to ``Address`` twice, using
-        an alias the second time.  We use :func:`~sqlalchemy.orm.aliased`
-        to create a distinct alias of ``Address``, and join
-        to it using the ``target, onclause`` form, so that the
-        alias can be specified explicitly as the target along with
-        the relationship to instruct how the ON clause should proceed::
-
-            a_alias = aliased(Address)
-
-            q = session.query(User).\\
-                    join(User.addresses).\\
-                    join(a_alias, User.addresses).\\
-                    filter(Address.email_address=='ed@foo.com').\\
-                    filter(a_alias.email_address=='ed@bar.com')
-
-        Where above, the generated SQL would be similar to::
-
-            SELECT user.* FROM user
-                JOIN address ON user.id = address.user_id
-                JOIN address AS address_1 ON user.id=address_1.user_id
-                WHERE address.email_address = :email_address_1
-                AND address_1.email_address = :email_address_2
-
-        The two-argument calling form of :meth:`~.Query.join`
-        also allows us to construct arbitrary joins with SQL-oriented
-        "on clause" expressions, not relying upon configured relationships
-        at all.  Any SQL expression can be passed as the ON clause
-        when using the two-argument form, which should refer to the target
-        entity in some way as well as an applicable source entity::
-
-            q = session.query(User).join(Address, User.id==Address.user_id)
-
-        .. versionchanged:: 0.7
-            In SQLAlchemy 0.6 and earlier, the two argument form of
-            :meth:`~.Query.join` requires the usage of a tuple:
-            ``query(User).join((Address, User.id==Address.user_id))``\ .
-            This calling form is accepted in 0.7 and further, though
-            is not necessary unless multiple join conditions are passed to
-            a single :meth:`~.Query.join` call, which itself is also not
-            generally necessary as it is now equivalent to multiple
-            calls (this wasn't always the case).
-
-        **Advanced Join Targeting and Adaption**
-
-        There is a lot of flexibility in what the "target" can be when using
-        :meth:`~.Query.join`.   As noted previously, it also accepts
-        :class:`.Table` constructs and other selectables such as
-        :func:`.alias` and :func:`.select` constructs, with either the one
-        or two-argument forms::
-
-            addresses_q = select([Address.user_id]).\\
-                        where(Address.email_address.endswith("@bar.com")).\\
-                        alias()
-
-            q = session.query(User).\\
-                        join(addresses_q, addresses_q.c.user_id==User.id)
-
-        :meth:`~.Query.join` also features the ability to *adapt* a
-        :meth:`~sqlalchemy.orm.relationship` -driven ON clause to the target
-        selectable. Below we construct a JOIN from ``User`` to a subquery
-        against ``Address``, allowing the relationship denoted by
-        ``User.addresses`` to *adapt* itself to the altered target::
-
-            address_subq = session.query(Address).\\
-                            filter(Address.email_address == 'ed@foo.com').\\
-                            subquery()
-
-            q = session.query(User).join(address_subq, User.addresses)
-
-        Producing SQL similar to::
-
-            SELECT user.* FROM user
-                JOIN (
-                    SELECT address.id AS id,
-                            address.user_id AS user_id,
-                            address.email_address AS email_address
-                    FROM address
-                    WHERE address.email_address = :email_address_1
-                ) AS anon_1 ON user.id = anon_1.user_id
-
-        The above form allows one to fall back onto an explicit ON
-        clause at any time::
-
-            q = session.query(User).\\
-                    join(address_subq, User.id==address_subq.c.user_id)
-
-        **Controlling what to Join From**
-
-        While :meth:`~.Query.join` exclusively deals with the "right"
-        side of the JOIN, we can also control the "left" side, in those
-        cases where it's needed, using :meth:`~.Query.select_from`.
-        Below we construct a query against ``Address`` but can still
-        make usage of ``User.addresses`` as our ON clause by instructing
-        the :class:`.Query` to select first from the ``User``
-        entity::
-
-            q = session.query(Address).select_from(User).\\
-                            join(User.addresses).\\
-                            filter(User.name == 'ed')
-
-        Which will produce SQL similar to::
-
-            SELECT address.* FROM user
-                JOIN address ON user.id=address.user_id
-                WHERE user.name = :name_1
-
-        **Constructing Aliases Anonymously**
-
-        :meth:`~.Query.join` can construct anonymous aliases
-        using the ``aliased=True`` flag.  This feature is useful
-        when a query is being joined algorithmically, such as
-        when querying self-referentially to an arbitrary depth::
-
-            q = session.query(Node).\\
-                    join("children", "children", aliased=True)
-
-        When ``aliased=True`` is used, the actual "alias" construct
-        is not explicitly available.  To work with it, methods such as
-        :meth:`.Query.filter` will adapt the incoming entity to
-        the last join point::
-
-            q = session.query(Node).\\
-                    join("children", "children", aliased=True).\\
-                    filter(Node.name == 'grandchild 1')
-
-        When using automatic aliasing, the ``from_joinpoint=True``
-        argument can allow a multi-node join to be broken into
-        multiple calls to :meth:`~.Query.join`, so that
-        each path along the way can be further filtered::
-
-            q = session.query(Node).\\
-                    join("children", aliased=True).\\
-                    filter(Node.name='child 1').\\
-                    join("children", aliased=True, from_joinpoint=True).\\
-                    filter(Node.name == 'grandchild 1')
-
-        The filtering aliases above can then be reset back to the
-        original ``Node`` entity using :meth:`~.Query.reset_joinpoint`::
-
-            q = session.query(Node).\\
-                    join("children", "children", aliased=True).\\
-                    filter(Node.name == 'grandchild 1').\\
-                    reset_joinpoint().\\
-                    filter(Node.name == 'parent 1)
-
-        For an example of ``aliased=True``, see the distribution
-        example :ref:`examples_xmlpersistence` which illustrates
-        an XPath-like query system using algorithmic joins.
-
-        :param \*props: A collection of one or more join conditions,
-         each consisting of a relationship-bound attribute or string
-         relationship name representing an "on clause", or a single
-         target entity, or a tuple in the form of ``(target, onclause)``.
-         A special two-argument calling form of the form ``target, onclause``
-         is also accepted.
-        :param aliased=False: If True, indicate that the JOIN target should be
-         anonymously aliased.  Subsequent calls to :meth:`~.Query.filter`
-         and similar will adapt the incoming criterion to the target
-         alias, until :meth:`~.Query.reset_joinpoint` is called.
-        :param from_joinpoint=False: When using ``aliased=True``, a setting
-         of True here will cause the join to be from the most recent
-         joined target, rather than starting back from the original
-         FROM clauses of the query.

-
-        This method is similar to the :meth:`.Query.select_from`
-        method, in that it sets the FROM clause of the query.  However,
-        where :meth:`.Query.select_from` only affects what is placed
-        in the FROM, this method also applies the given selectable
-        to replace the FROM which the selected entities would normally
-        select from.
-
-        The given ``from_obj`` must be an instance of a :class:`.FromClause`,
-        e.g. a :func:`.select` or :class:`.Alias` construct.
-
-        An example would be a :class:`.Query` that selects ``User`` entities,
-        but uses :meth:`.Query.select_entity_from` to have the entities
-        selected from a :func:`.select` construct instead of the
-        base ``user`` table::
-
-            select_stmt = select([User]).where(User.id == 7)
-
-            q = session.query(User).\\
-                    select_entity_from(select_stmt).\\
-                    filter(User.name == 'ed')
-
-        The query generated will select ``User`` entities directly
-        from the given :func:`.select` construct, and will be::
-
-            SELECT anon_1.id AS anon_1_id, anon_1.name AS anon_1_name
-            FROM (SELECT "user".id AS id, "user".name AS name
-            FROM "user"
-            WHERE "user".id = :id_1) AS anon_1
-            WHERE anon_1.name = :name_1
-
-        Notice above that even the WHERE criterion was "adapted" such that
-        the ``anon_1`` subquery effectively replaces all references to the
-        ``user`` table, except for the one that it refers to internally.
-
-        Compare this to :meth:`.Query.select_from`, which as of
-        version 0.9, does not affect existing entities.  The
-        statement below::
-
-            q = session.query(User).\\
-                    select_from(select_stmt).\\
-                    filter(User.name == 'ed')
-
-        Produces SQL where both the ``user`` table as well as the
-        ``select_stmt`` construct are present as separate elements
-        in the FROM clause.  No "adaptation" of the ``user`` table
-        is applied::
-
-            SELECT "user".id AS user_id, "user".name AS user_name
-            FROM "user", (SELECT "user".id AS id, "user".name AS name
-            FROM "user"
-            WHERE "user".id = :id_1) AS anon_1
-            WHERE "user".name = :name_1
-
-        :meth:`.Query.select_entity_from` maintains an older
-        behavior of :meth:`.Query.select_from`.  In modern usage,
-        similar results can also be achieved using :func:`.aliased`::
-
-            select_stmt = select([User]).where(User.id == 7)
-            user_from_select = aliased(User, select_stmt.alias())
-
-            q = session.query(user_from_select)
-
-        :param from_obj: a :class:`.FromClause` object that will replace
-         the FROM clause of this :class:`.Query`.

-
-        .. versionadded:: 0.8
-            :meth:`.Query.select_entity_from` was added to specify

-
-        This corresponds to a parent-child or associative table relationship.  The
-        constructed class is an instance of :class:`.RelationshipProperty`.
-
-        A typical :func:`.relationship`, used in a classical mapping::
-
-           mapper(Parent, properties={
-             'children': relationship(Child)
-           })
-
-        Some arguments accepted by :func:`.relationship` optionally accept a
-        callable function, which when called produces the desired value.
-        The callable is invoked by the parent :class:`.Mapper` at "mapper
-        initialization" time, which happens only when mappers are first used, and
-        is assumed to be after all mappings have been constructed.  This can be
-        used to resolve order-of-declaration and other dependency issues, such as
-        if ``Child`` is declared below ``Parent`` in the same file::
-
-            mapper(Parent, properties={
-                "children":relationship(lambda: Child,
-                                    order_by=lambda: Child.id)
-            })
-
-        When using the :ref:`declarative_toplevel` extension, the Declarative
-        initializer allows string arguments to be passed to :func:`.relationship`.
-        These string arguments are converted into callables that evaluate
-        the string as Python code, using the Declarative
-        class-registry as a namespace.  This allows the lookup of related
-        classes to be automatic via their string name, and removes the need to
-        import related classes at all into the local module space::
-
-            from sqlalchemy.ext.declarative import declarative_base
-
-            Base = declarative_base()
-
-            class Parent(Base):
-                __tablename__ = 'parent'
-                id = Column(Integer, primary_key=True)
-                children = relationship("Child", order_by="Child.id")

-
-        :param argument:
-          a mapped class, or actual :class:`.Mapper` instance, representing the
-          target of the relationship.
-
-          :paramref:`~.relationship.argument` may also be passed as a callable function
-          which is evaluated at mapper initialization time, and may be passed as a
-          Python-evaluable string when using Declarative.

-            :ref:`declarative_configuring_relationships` - further detail
-            on relationship configuration when using Declarative.
-
-        :param secondary:
-          for a many-to-many relationship, specifies the intermediary
-          table, and is typically an instance of :class:`.Table`.
-          In less common circumstances, the argument may also be specified
-          as an :class:`.Alias` construct, or even a :class:`.Join` construct.
-
-          :paramref:`~.relationship.secondary` may
-          also be passed as a callable function which is evaluated at
-          mapper initialization time.  When using Declarative, it may also
-          be a string argument noting the name of a :class:`.Table` that is
-          present in the :class:`.MetaData` collection associated with the
-          parent-mapped :class:`.Table`.
-
-          The :paramref:`~.relationship.secondary` keyword argument is typically
-          applied in the case where the intermediary :class:`.Table` is not

-        :param distinct_target_key=None:

-          the DISTINCT keyword will be applied in those cases when the target

-          When set to ``True``, the DISTINCT keyword is applied to the innermost
-          SELECT unconditionally.
-
-          It may be desirable to set this flag to False when the DISTINCT is
-          reducing performance of the innermost subquery beyond that of what
-          duplicate innermost rows may be causing.

-
-        :param foreign_keys:
-
-          a list of columns which are to be used as "foreign key"
-          columns, or columns which refer to the value in a remote
-          column, within the context of this :func:`.relationship`
-          object's :paramref:`~.relationship.primaryjoin` condition.
-          That is, if the :paramref:`~.relationship.primaryjoin`
-          condition of this :func:`.relationship` is ``a.id ==
-          b.a_id``, and the values in ``b.a_id`` are required to be
-          present in ``a.id``, then the "foreign key" column of this
-          :func:`.relationship` is ``b.a_id``.
-
-          In normal cases, the :paramref:`~.relationship.foreign_keys`
-          parameter is **not required.** :func:`.relationship` will
-          automatically determine which columns in the
-          :paramref:`~.relationship.primaryjoin` conditition are to be
-          considered "foreign key" columns based on those
-          :class:`.Column` objects that specify :class:`.ForeignKey`,
-          or are otherwise listed as referencing columns in a
-          :class:`.ForeignKeyConstraint` construct.
-          :paramref:`~.relationship.foreign_keys` is only needed when:
-
-            1. There is more than one way to construct a join from the local
-               table to the remote table, as there are multiple foreign key
-               references present.  Setting ``foreign_keys`` will limit the
-               :func:`.relationship` to consider just those columns specified
-               here as "foreign".
-
-               .. versionchanged:: 0.8
-                    A multiple-foreign key join ambiguity can be resolved by
-                    setting the :paramref:`~.relationship.foreign_keys` parameter alone, without the
-                    need to explicitly set :paramref:`~.relationship.primaryjoin` as well.
-
-            2. The :class:`.Table` being mapped does not actually have
-               :class:`.ForeignKey` or :class:`.ForeignKeyConstraint`
-               constructs present, often because the table
-               was reflected from a database that does not support foreign key
-               reflection (MySQL MyISAM).
-
-            3. The :paramref:`~.relationship.primaryjoin` argument is used to construct a non-standard
-               join condition, which makes use of columns or expressions that do
-               not normally refer to their "parent" column, such as a join condition
-               expressed by a complex comparison using a SQL function.
-
-          The :func:`.relationship` construct will raise informative
-          error messages that suggest the use of the
-          :paramref:`~.relationship.foreign_keys` parameter when
-          presented with an ambiguous condition.   In typical cases,
-          if :func:`.relationship` doesn't raise any exceptions, the
-          :paramref:`~.relationship.foreign_keys` parameter is usually
-          not needed.
-
-          :paramref:`~.relationship.foreign_keys` may also be passed as a callable function
-          which is evaluated at mapper initialization time, and may be passed as a
-          Python-evaluable string when using Declarative.

-
-        :param innerjoin=False:
-          when ``True``, joined eager loads will use an inner join to join
-          against related tables instead of an outer join.  The purpose
-          of this option is generally one of performance, as inner joins
-          generally perform better than outer joins.
-
-          This flag can be set to ``True`` when the relationship references an
-          object via many-to-one using local foreign keys that are not nullable,
-          or when the reference is one-to-one or a collection that is guaranteed
-          to have one or at least one entry.
-
-          If the joined-eager load is chained onto an existing LEFT OUTER JOIN,
-          ``innerjoin=True`` will be bypassed and the join will continue to
-          chain as LEFT OUTER JOIN so that the results don't change.  As an alternative,
-          specify the value ``"nested"``.  This will instead nest the join
-          on the right side, e.g. using the form "a LEFT OUTER JOIN (b JOIN c)".
-
-          .. versionadded:: 0.9.4 Added ``innerjoin="nested"`` option to support

-          relationship.  The number counts how many times the same Mapper
-          shall be present in the loading condition along a particular join
-          branch.  When left at its default of ``None``, eager loaders
-          will stop chaining when they encounter a the same target mapper
-          which is already higher up in the chain.  This option applies
-          both to joined- and subquery- eager loaders.

-
-        :param lazy='select': specifies
-          how the related items should be loaded.  Default value is
-          ``select``.  Values include:
-
-          * ``select`` - items should be loaded lazily when the property is first
-            accessed, using a separate SELECT statement, or identity map
-            fetch for simple many-to-one references.
-
-          * ``immediate`` - items should be loaded as the parents are loaded,
-            using a separate SELECT statement, or identity map fetch for
-            simple many-to-one references.
-
-          * ``joined`` - items should be loaded "eagerly" in the same query as
-            that of the parent, using a JOIN or LEFT OUTER JOIN.  Whether
-            the join is "outer" or not is determined by the
-            :paramref:`~.relationship.innerjoin` parameter.
-
-          * ``subquery`` - items should be loaded "eagerly" as the parents are
-            loaded, using one additional SQL statement, which issues a JOIN to a
-            subquery of the original statement, for each collection requested.
-
-          * ``noload`` - no loading should occur at any time.  This is to
-            support "write-only" attributes, or attributes which are
-            populated in some manner specific to the application.
-
-          * ``dynamic`` - the attribute will return a pre-configured
-            :class:`.Query` object for all read
-            operations, onto which further filtering operations can be
-            applied before iterating the results.  See

-        :param load_on_pending=False:
-          Indicates loading behavior for transient or pending parent objects.
-
-          When set to ``True``, causes the lazy-loader to
-          issue a query for a parent object that is not persistent, meaning it has
-          never been flushed.  This may take effect for a pending object when
-          autoflush is disabled, or for a transient object that has been
-          "attached" to a :class:`.Session` but is not part of its pending
-          collection.
-
-          The :paramref:`~.relationship.load_on_pending` flag does not improve behavior
-          when the ORM is used normally - object references should be constructed
-          at the object level, not at the foreign key level, so that they
-          are present in an ordinary way before a flush proceeds.  This flag
-          is not not intended for general use.
-
-          .. seealso::
-
-              :meth:`.Session.enable_relationship_loading` - this method establishes
-              "load on pending" behavior for the whole object, and also allows
-              loading on objects that remain transient or detached.
-
-        :param order_by:
-          indicates the ordering that should be applied when loading these
-          items.  :paramref:`~.relationship.order_by` is expected to refer to one
-          of the :class:`.Column`
-          objects to which the target class is mapped, or
-          the attribute itself bound to the target class which refers
-          to the column.
-
-          :paramref:`~.relationship.order_by` may also be passed as a callable function
-          which is evaluated at mapper initialization time, and may be passed as a
-          Python-evaluable string when using Declarative.
-
-        :param passive_deletes=False:
-           Indicates loading behavior during delete operations.
-
-           A value of True indicates that unloaded child items should not
-           be loaded during a delete operation on the parent.  Normally,
-           when a parent item is deleted, all child items are loaded so
-           that they can either be marked as deleted, or have their
-           foreign key to the parent set to NULL.  Marking this flag as
-           True usually implies an ON DELETE <CASCADE|SET NULL> rule is in
-           place which will handle updating/deleting child rows on the
-           database side.
-
-           Additionally, setting the flag to the string value 'all' will
-           disable the "nulling out" of the child foreign keys, when there
-           is no delete or delete-orphan cascade enabled.  This is
-           typically used when a triggering or error raise scenario is in
-           place on the database side.  Note that the foreign key
-           attributes on in-session child objects will not be changed
-           after a flush occurs so this is a very special use-case
-           setting.

-           .. seealso::

-
-        :param passive_updates=True:
-          Indicates loading and INSERT/UPDATE/DELETE behavior when the
-          source of a foreign key value changes (i.e. an "on update"
-          cascade), which are typically the primary key columns of the
-          source row.
-
-          When True, it is assumed that ON UPDATE CASCADE is configured on
-          the foreign key in the database, and that the database will
-          handle propagation of an UPDATE from a source column to
-          dependent rows.  Note that with databases which enforce
-          referential integrity (i.e. PostgreSQL, MySQL with InnoDB tables),
-          ON UPDATE CASCADE is required for this operation.  The
-          relationship() will update the value of the attribute on related
-          items which are locally present in the session during a flush.
-
-          When False, it is assumed that the database does not enforce
-          referential integrity and will not be issuing its own CASCADE
-          operation for an update.  The relationship() will issue the
-          appropriate UPDATE statements to the database in response to the
-          change of a referenced key, and items locally present in the
-          session during a flush will also be refreshed.
-
-          This flag should probably be set to False if primary key changes
-          are expected and the database in use doesn't support CASCADE
-          (i.e. SQLite, MySQL MyISAM tables).

-          DELETE. Currently, it also will issue an UPDATE after the
-          instance was UPDATEd as well, although this technically should
-          be improved. This flag is used to handle saving bi-directional
-          dependencies between two individual rows (i.e. each row
-          references the other), where it would otherwise be impossible to
-          INSERT or DELETE both rows fully since one row exists before the
-          other. Use this flag when a particular mapping arrangement will
-          incur two rows that are dependent on each other, such as a table
-          that has a one-to-many relationship to a set of child rows, and
-          also has a column that references a single child row within that
-          list (i.e. both tables contain a foreign key to each other). If
-          a flush operation returns an error that a "cyclical
-          dependency" was detected, this is a cue that you might want to
-          use :paramref:`~.relationship.post_update` to "break" the cycle.

-
-            :func:`.remote` - an annotation function that accomplishes the same

-          is, a relationship that specifies ``lazy="dynamic"`` or was

-          computed based on the foreign key relationships of the association and
-          child tables.
-
-          :paramref:`~.relationship.secondaryjoin` may also be passed as a callable function
-          which is evaluated at mapper initialization time, and may be passed as a

-          when True, installs a validator which will prevent objects
-          from being associated with more than one parent at a time.
-          This is used for many-to-one or many-to-many relationships that
-          should be treated either as one-to-one or one-to-many.  Its usage
-          is optional, except for :func:`.relationship` constructs which
-          are many-to-one or many-to-many and also
-          specify the ``delete-orphan`` cascade option.  The :func:`.relationship`
-          construct itself will raise an error instructing when this option
-          is required.

-
-        :param uselist:
-          a boolean that indicates if this property should be loaded as a
-          list or a scalar. In most cases, this value is determined
-          automatically by :func:`.relationship` at mapper configuration
-          time, based on the type and direction
-          of the relationship - one to many forms a list, many to one
-          forms a scalar, many to many is a list. If a scalar is desired
-          where normally a list would be present, such as a bi-directional
-          one-to-one relationship, set :paramref:`~.relationship.uselist` to False.
-
-          The :paramref:`~.relationship.uselist` flag is also available on an
-          existing :func:`.relationship` construct as a read-only attribute, which
-          can be used to determine if this :func:`.relationship` deals with
-          collections or scalar attributes::

-              relationship pattern, which is typically when the
-              :paramref:`~.relationship.uselist` flag is needed.
-
-        :param viewonly=False:
-          when set to True, the relationship is used only for loading objects,
-          and not for any persistence operation.  A :func:`.relationship`
-          which specifies :paramref:`~.relationship.viewonly` can work
-          with a wider range of SQL operations within the :paramref:`~.relationship.primaryjoin`
-          condition, including operations that feature the use of
-          a variety of comparison operators as well as SQL functions such
-          as :func:`~.sql.expression.cast`.  The :paramref:`~.relationship.viewonly`
-          flag is also of general use when defining any kind of :func:`~.relationship`
-          that doesn't represent the full set of related objects, to prevent
-          modifications of the collection from resulting in persistence operations.

-    """A :class:`.Session`-level transaction.
-
-    :class:`.SessionTransaction` is a mostly behind-the-scenes object
-    not normally referenced directly by application code.   It coordinates
-    among multiple :class:`.Connection` objects, maintaining a database
-    transaction for each one individually, committing or rolling them
-    back all at once.   It also provides optional two-phase commit behavior
-    which can augment this coordination operation.
-
-    The :attr:`.Session.transaction` attribute of :class:`.Session`
-    refers to the current :class:`.SessionTransaction` object in use, if any.
-
-
-    A :class:`.SessionTransaction` is associated with a :class:`.Session`
-    in its default mode of ``autocommit=False`` immediately, associated
-    with no database connections.  As the :class:`.Session` is called upon
-    to emit SQL on behalf of various :class:`.Engine` or :class:`.Connection`
-    objects, a corresponding :class:`.Connection` and associated
-    :class:`.Transaction` is added to a collection within the
-    :class:`.SessionTransaction` object, becoming one of the
-    connection/transaction pairs maintained by the
-    :class:`.SessionTransaction`.
-
-    The lifespan of the :class:`.SessionTransaction` ends when the
-    :meth:`.Session.commit`, :meth:`.Session.rollback` or
-    :meth:`.Session.close` methods are called.  At this point, the
-    :class:`.SessionTransaction` removes its association with its parent
-    :class:`.Session`.   A :class:`.Session` that is in ``autocommit=False``
-    mode will create a new :class:`.SessionTransaction` to replace it
-    immediately, whereas a :class:`.Session` that's in ``autocommit=True``
-    mode will remain without a :class:`.SessionTransaction` until the
-    :meth:`.Session.begin` method is called.
-
-    Another detail of :class:`.SessionTransaction` behavior is that it is
-    capable of "nesting".  This means that the :meth:`.Session.begin` method
-    can be called while an existing :class:`.SessionTransaction` is already
-    present, producing a new :class:`.SessionTransaction` that temporarily
-    replaces the parent :class:`.SessionTransaction`.   When a
-    :class:`.SessionTransaction` is produced as nested, it assigns itself to
-    the :attr:`.Session.transaction` attribute.  When it is ended via
-    :meth:`.Session.commit` or :meth:`.Session.rollback`, it restores its
-    parent :class:`.SessionTransaction` back onto the
-    :attr:`.Session.transaction` attribute.  The behavior is effectively a
-    stack, where :attr:`.Session.transaction` refers to the current head of
-    the stack.
-
-    The purpose of this stack is to allow nesting of
-    :meth:`.Session.rollback` or :meth:`.Session.commit` calls in context
-    with various flavors of :meth:`.Session.begin`. This nesting behavior
-    applies to when :meth:`.Session.begin_nested` is used to emit a
-    SAVEPOINT transaction, and is also used to produce a so-called
-    "subtransaction" which allows a block of code to use a
-    begin/rollback/commit sequence regardless of whether or not its enclosing
-    code block has begun a transaction.  The :meth:`.flush` method, whether
-    called explicitly or via autoflush, is the primary consumer of the
-    "subtransaction" feature, in that it wishes to guarantee that it works
-    within in a transaction block regardless of whether or not the
-    :class:`.Session` is in transactional mode when the method is called.

-        See also the :class:`.sessionmaker` function which is used to

-        set of arguments.
-
-        :param autocommit:
-
-          .. warning::
-
-             The autocommit flag is **not for general use**, and if it is used,
-             queries should only be invoked within the span of a
-             :meth:`.Session.begin` / :meth:`.Session.commit` pair.   Executing
-             queries outside of a demarcated transaction is a legacy mode
-             of usage, and can in some cases lead to concurrent connection
-             checkouts.
-
-          Defaults to ``False``. When ``True``, the
-          :class:`.Session` does not keep a persistent transaction running, and
-          will acquire connections from the engine on an as-needed basis,
-          returning them immediately after their use. Flushes will begin and
-          commit (or possibly rollback) their own transaction if no
-          transaction is present. When using this mode, the
-          :meth:`.Session.begin` method is used to explicitly start
-          transactions.
-
-          .. seealso::
-
-            :ref:`session_autocommit`
-
-        :param autoflush: When ``True``, all query operations will issue a
-           ``flush()`` call to this ``Session`` before proceeding. This is a
-           convenience feature so that ``flush()`` need not be called
-           repeatedly in order for database queries to retrieve results. It's
-           typical that ``autoflush`` is used in conjunction with
-           ``autocommit=False``. In this scenario, explicit calls to
-           ``flush()`` are rarely needed; you usually only need to call
-           ``commit()`` (which flushes) to finalize changes.
-
-        :param bind: An optional ``Engine`` or ``Connection`` to which this
-           ``Session`` should be bound. When specified, all SQL operations
-           performed by this session will execute via this connectable.
-
-        :param binds: An optional dictionary which contains more granular
-           "bind" information than the ``bind`` parameter provides. This
-           dictionary can map individual ``Table`` instances as well as
-           ``Mapper`` instances to individual ``Engine`` or ``Connection``
-           objects. Operations which proceed relative to a particular
-           ``Mapper`` will consult this dictionary for the direct ``Mapper``
-           instance as well as the mapper's ``mapped_table`` attribute in
-           order to locate an connectable to use. The full resolution is
-           described in the ``get_bind()`` method of ``Session``.
-           Usage looks like::
-
-            Session = sessionmaker(binds={
-                SomeMappedClass: create_engine('postgresql://engine1'),
-                somemapper: create_engine('postgresql://engine2'),
-                some_table: create_engine('postgresql://engine3'),
-                })
-
-          Also see the :meth:`.Session.bind_mapper`
-          and :meth:`.Session.bind_table` methods.
-
-        :param \class_: Specify an alternate class other than
-           ``sqlalchemy.orm.session.Session`` which should be used by the
-           returned class. This is the only argument that is local to the
-           ``sessionmaker()`` function, and is not sent directly to the
-           constructor for ``Session``.
-
-        :param _enable_transaction_accounting:  Defaults to ``True``.  A
-           legacy-only flag which when ``False`` disables *all* 0.5-style
-           object accounting on transaction boundaries, including auto-expiry
-           of instances on rollback and commit, maintenance of the "new" and
-           "deleted" lists upon rollback, and autoflush of pending changes upon
-           begin(), all of which are interdependent.

-
-        The second positional argument to :meth:`.Session.execute` is an
-        optional parameter set.  Similar to that of
-        :meth:`.Connection.execute`, whether this is passed as a single
-        dictionary, or a list of dictionaries, determines whether the DBAPI
-        cursor's ``execute()`` or ``executemany()`` is used to execute the
-        statement.   An INSERT construct may be invoked for a single row::
-
-            result = session.execute(users.insert(), {"id": 7, "name": "somename"})
-
-        or for multiple rows::
-
-            result = session.execute(users.insert(), [

-                                ])
-
-        The statement is executed within the current transactional context of
-        this :class:`.Session`.   The :class:`.Connection` which is used
-        to execute the statement can also be acquired directly by
-        calling the :meth:`.Session.connection` method.  Both methods use
-        a rule-based resolution scheme in order to determine the
-        :class:`.Connection`, which in the average case is derived directly
-        from the "bind" of the :class:`.Session` itself, and in other cases
-        can be based on the :func:`.mapper`
-        and :class:`.Table` objects passed to the method; see the documentation
-        for :meth:`.Session.get_bind` for a full description of this scheme.
-
-        The :meth:`.Session.execute` method does *not* invoke autoflush.
-
-        The :class:`.ResultProxy` returned by the :meth:`.Session.execute`
-        method is returned with the "close_with_result" flag set to true;
-        the significance of this flag is that if this :class:`.Session` is
-        autocommitting and does not have a transaction-dedicated
-        :class:`.Connection` available, a temporary :class:`.Connection` is
-        established for the statement execution, which is closed (meaning,
-        returned to the connection pool) when the :class:`.ResultProxy` has
-        consumed all available data. This applies *only* when the
-        :class:`.Session` is configured with autocommit=True and no
-        transaction has been started.

-            "executemany" will be invoked.  The keys in each dictionary
-            must correspond to parameter names present in the statement.
-

-         events, and without the need to reconcile the incoming data with
-         any existing related objects or collections that might not
-         be loaded.  The resulting objects from ``load=False`` are always
-         produced as "clean", so it is only appropriate that the given objects
-         should be "clean" as well, else this suggests a mis-use of the method.

-            use cases and is not recommended for general use.

-        will attempt to load a value from the database using this
-        :class:`.Session` as the source of connectivity.  The values
-        will be loaded based on foreign key values present on this
-        object - it follows that this functionality
-        generally only works for many-to-one-relationships.
-
-        The object will be attached to this session, but will
-        **not** participate in any persistence operations; its state
-        for almost all purposes will remain either "transient" or
-        "detached", except for the case of relationship loading.
-
-        Also note that backrefs will often not work as expected.
-        Altering a relationship-bound attribute on the target object
-        may not fire off a backref event, if the effective value
-        is what was already loaded from a foreign-key-holding value.
-
-        The :meth:`.Session.enable_relationship_loading` method is
-        similar to the ``load_on_pending`` flag on :func:`.relationship`.   Unlike
-        that flag, :meth:`.Session.enable_relationship_loading` allows
-        an object to remain transient while still being able to load
-        related items.
-
-        To make a transient object associated with a :class:`.Session`
-        via :meth:`.Session.enable_relationship_loading` pending, add
-        it to the :class:`.Session` using :meth:`.Session.add` normally.
-
-        :meth:`.Session.enable_relationship_loading` does not improve
-        behavior when the ORM is used normally - object references should be
-        constructed at the object level, not at the foreign key level, so
-        that they are present in an ordinary way before flush()

-
-        It is in effect a more expensive and accurate
-        version of checking for the given instance in the
-        :attr:`.Session.dirty` collection; a full test for
-        each attribute's net "dirty" status is performed.
-
-        E.g.::
-
-            return session.is_modified(someobject)
-
-        .. versionchanged:: 0.8
-            When using SQLAlchemy 0.7 and earlier, the ``passive``
-            flag should **always** be explicitly set to ``True``,
-            else SQL loads/autoflushes may proceed which can affect
-            the modified state itself:
-            ``session.is_modified(someobject, passive=True)``\ .
-            In 0.8 and above, the behavior is corrected and
-            this flag is ignored.
-
-        A few caveats to this method apply:
-
-        * Instances present in the :attr:`.Session.dirty` collection may report
-          ``False`` when tested with this method.  This is because
-          the object may have received change events via attribute
-          mutation, thus placing it in :attr:`.Session.dirty`,
-          but ultimately the state is the same as that loaded from
-          the database, resulting in no net change here.
-        * Scalar attributes may not have recorded the previously set
-          value when a new value was applied, if the attribute was not loaded,
-          or was expired, at the time the new value was received - in these
-          cases, the attribute is assumed to have a change, even if there is
-          ultimately no net change against its database value. SQLAlchemy in
-          most cases does not need the "old" value when a set event occurs, so
-          it skips the expense of a SQL call if the old value isn't present,
-          based on the assumption that an UPDATE of the scalar value is
-          usually needed, and in those few cases where it isn't, is less
-          expensive on average than issuing a defensive SELECT.
-
-          The "old" value is fetched unconditionally upon set only if the
-          attribute container has the ``active_history`` flag set to ``True``.
-          This flag is set typically for primary key attributes and scalar
-          object references that are not a simple many-to-one.  To set this
-          flag for any arbitrary mapped column, use the ``active_history``
-          argument with :func:`.column_property`.
-
-        :param instance: mapped instance to be tested for pending changes.
-        :param include_collections: Indicates if multivalued collections
-         should be included in the operation.  Setting this to ``False`` is a
-         way to detect only local-column based properties (i.e. scalar columns
-         or many-to-one foreign keys) that would result in an UPDATE for this
-         instance upon flush.
-        :param passive:
-         .. versionchanged:: 0.8
-             Ignored for backwards compatibility.

-
-        The :class:`.Session` in its default mode of ``autocommit=False``
-        is essentially always in "transaction mode", in that a
-        :class:`.SessionTransaction` is associated with it as soon as
-        it is instantiated.  This :class:`.SessionTransaction` is immediately
-        replaced with a new one as soon as it is ended, due to a rollback,
-        commit, or close operation.
-
-        "Transaction mode" does *not* indicate whether
-        or not actual database connection resources are in use;  the
-        :class:`.SessionTransaction` object coordinates among zero or more
-        actual database transactions, and starts out with none, accumulating
-        individual DBAPI connections as different data sources are used
-        within its scope.   The best way to track when a particular
-        :class:`.Session` has actually begun to use DBAPI resources is to
-        implement a listener using the :meth:`.SessionEvents.after_begin`
-        method, which will deliver both the :class:`.Session` as well as the
-        target :class:`.Connection` to a user-defined event listener.
-
-        The "partial rollback" state refers to when an "inner" transaction,
-        typically used during a flush, encounters an error and emits a
-        rollback of the DBAPI connection.  At this point, the
-        :class:`.Session` is in "partial rollback" and awaits for the user to
-        call :meth:`.Session.rollback`, in order to close out the
-        transaction stack.  It is in this "partial rollback" period that the
-        :attr:`.is_active` flag returns False.  After the call to
-        :meth:`.Session.rollback`, the :class:`.SessionTransaction` is replaced
-        with a new one and :attr:`.is_active` returns ``True`` again.
-
-        When a :class:`.Session` is used in ``autocommit=True`` mode, the
-        :class:`.SessionTransaction` is only instantiated within the scope
-        of a flush call, or when :meth:`.Session.begin` is called.  So
-        :attr:`.is_active` will always be ``False`` outside of a flush or
-        :meth:`.Session.begin` block in this mode, and will be ``True``
-        within the :meth:`.Session.begin` block as long as it doesn't enter
-        "partial rollback" state.
-
-        From all the above, it follows that the only purpose to this flag is
-        for application frameworks that wish to detect is a "rollback" is
-        necessary within a generic error handling routine, for
-        :class:`.Session` objects that would otherwise be in
-        "partial rollback" mode.  In a typical integration case, this is also
-        not necessary as it is standard practice to emit
-        :meth:`.Session.rollback` unconditionally within the outermost
-        exception catch.
-
-        To track the transactional state of a :class:`.Session` fully,
-        use event listeners, primarily the :meth:`.SessionEvents.after_begin`,
-        :meth:`.SessionEvents.after_commit`,
-        :meth:`.SessionEvents.after_rollback` and related events.

-class Load(Generative, MapperOption):
-    """Represents loader options which modify the state of a
-    :class:`.Query` in order to affect how various mapped attributes are loaded.
-
-    .. versionadded:: 0.9.0 The :meth:`.Load` system is a new foundation for
-       the existing system of loader options, including options such as
-       :func:`.orm.joinedload`, :func:`.orm.defer`, and others.   In particular,
-       it introduces a new method-chained system that replaces the need for
-       dot-separated paths as well as "_all()" options such as :func:`.orm.joinedload_all`.
-
-    A :class:`.Load` object can be used directly or indirectly.  To use one
-    directly, instantiate given the parent class.  This style of usage is
-    useful when dealing with a :class:`.Query` that has multiple entities,
-    or when producing a loader option that can be applied generically to
-    any style of query::
-
-        myopt = Load(MyClass).joinedload("widgets")
-
-    The above ``myopt`` can now be used with :meth:`.Query.options`::
-
-        session.query(MyClass).options(myopt)
-
-    The :class:`.Load` construct is invoked indirectly whenever one makes use
-    of the various loader options that are present in ``sqlalchemy.orm``, including
-    options such as :func:`.orm.joinedload`, :func:`.orm.defer`, :func:`.orm.subqueryload`,
-    and all the rest.  These constructs produce an "anonymous" form of the
-    :class:`.Load` object which tracks attributes and options, but is not linked
-    to a parent class until it is associated with a parent :class:`.Query`::
-
-        # produce "unbound" Load object
-        myopt = joinedload("widgets")
-
-        # when applied using options(), the option is "bound" to the
-        # class observed in the given query, e.g. MyClass
-        session.query(MyClass).options(myopt)
-
-    Whether the direct or indirect style is used, the :class:`.Load` object
-    returned now represents a specific "path" along the entities of a :class:`.Query`.
-    This path can be traversed using a standard method-chaining approach.
-    Supposing a class hierarchy such as ``User``, ``User.addresses -> Address``,
-    ``User.orders -> Order`` and ``Order.items -> Item``, we can specify a variety
-    of loader options along each element in the "path"::
-
-        session.query(User).options(
-                    joinedload("addresses"),
-                    subqueryload("orders").joinedload("items")
-                )
-
-    Where above, the ``addresses`` collection will be joined-loaded, the
-    ``orders`` collection will be subquery-loaded, and within that subquery load
-    the ``items`` collection will be joined-loaded.

-     normally be a :class:`.Alias` object corresponding to the :class:`.Table`
-     to which the class is mapped, or to a :func:`.select` construct that
-     is compatible with the mapping.   By default, a simple anonymous

-             To produce a :class:`.Connection` which refers to the
-             :meth:`.Pool.connect` method, use
-             :meth:`.Engine.contextual_connect`.
-
-             Note that other SQLAlchemy connectivity systems such as
-             :meth:`.Engine.execute` as well as the orm
-             :class:`.Session` make use of
-             :meth:`.Engine.contextual_connect` internally, so these functions
-             are compatible with the :paramref:`.Pool.use_threadlocal` setting.
-
-          .. seealso::
-
-            :ref:`threadlocal_strategy` - contains detail on the
-            "threadlocal" engine strategy, which provides a more comprehensive
-            approach to "threadlocal" connectivity for the specific
-            use case of using :class:`.Engine` and :class:`.Connection` objects
-            directly.
-
-        :param reset_on_return: Determine steps to take on
-          connections as they are returned to the pool.
-          reset_on_return can have any of these values:
-
-          * ``"rollback"`` - call rollback() on the connection,
-            to release locks and transaction resources.
-            This is the default value.  The vast majority
-            of use cases should leave this value set.
-          * ``True`` - same as 'rollback', this is here for
-            backwards compatibility.
-          * ``"commit"`` - call commit() on the connection,
-            to release locks and transaction resources.
-            A commit here may be desirable for databases that
-            cache query plans if a commit is emitted,
-            such as Microsoft SQL Server.  However, this
-            value is more dangerous than 'rollback' because
-            any data changes present on the transaction
-            are committed unconditionally.
-          * ``None`` - don't do anything on the connection.
-            This setting should only be made on a database
-            that has no transaction support at all,
-            namely MySQL MyISAM.   By not doing anything,
-            performance can be improved.   This
-            setting should **never be selected** for a
-            database that supports transactions,
-            as it will lead to deadlocks and stale
-            state.
-          * ``False`` - same as None, this is here for
-            backwards compatibility.

-    compiler extension documented in :ref:`sqlalchemy.ext.compiler_toplevel`
-    to extend :class:`.CreateColumn`.
-
-    Typical integration is to examine the incoming :class:`.Column`
-    object, and to redirect compilation if a particular flag or condition
-    is found::
-
-        from sqlalchemy import schema
-        from sqlalchemy.ext.compiler import compiles
-
-        @compiles(schema.CreateColumn)
-        def compile(element, compiler, **kw):
-            column = element.element
-
-            if "special" not in column.info:
-                return compiler.visit_create_column(element, **kw)
-
-            text = "%s SPECIAL DIRECTIVE %s" % (
-                    column.name,
-                    compiler.type_compiler.process(column.type)
-                )
-            default = compiler.get_column_default_string(column)
-            if default is not None:
-                text += " DEFAULT " + default
-
-            if not column.nullable:
-                text += " NOT NULL"
-
-            if column.constraints:
-                text += " ".join(
-                            compiler.process(const)
-                            for const in column.constraints)
-            return text
-
-    The above construct can be applied to a :class:`.Table` as follows::
-
-        from sqlalchemy import Table, Metadata, Column, Integer, String
-        from sqlalchemy import schema
-
-        metadata = MetaData()
-
-        table = Table('mytable', MetaData(),
-                Column('x', Integer, info={"special":True}, primary_key=True),
-                Column('y', String(50)),
-                Column('z', String(20), info={"special":True})
-            )
-
-        metadata.create_all(conn)
-
-    Above, the directives we've added to the :attr:`.Column.info` collection
-    will be detected by our custom compilation scheme::
-
-        CREATE TABLE mytable (
-                x SPECIAL DIRECTIVE INTEGER NOT NULL,
-                y VARCHAR(50),
-                z SPECIAL DIRECTIVE VARCHAR(20),
-            PRIMARY KEY (x)
-        )
-
-    The :class:`.CreateColumn` construct can also be used to skip certain
-    columns when producing a ``CREATE TABLE``.  This is accomplished by
-    creating a compilation rule that conditionally returns ``None``.
-    This is essentially how to produce the same effect as using the
-    ``system=True`` argument on :class:`.Column`, which marks a column
-    as an implicitly-present "system" column.
-
-    For example, suppose we wish to produce a :class:`.Table` which skips
-    rendering of the Postgresql ``xmin`` column against the Postgresql backend,
-    but on other backends does render it, in anticipation of a triggered rule.
-    A conditional compilation rule could skip this name only on Postgresql::
-
-        from sqlalchemy.schema import CreateColumn
-
-        @compiles(CreateColumn, "postgresql")
-        def skip_xmin(element, compiler, **kw):
-            if element.element.name == 'xmin':
-                return None
-            else:
-                return compiler.visit_create_column(element, **kw)
-
-
-        my_table = Table('mytable', metadata,
-                    Column('id', Integer, primary_key=True),
-                    Column('xmin', Integer)
-                )
-
-    Above, a :class:`.CreateTable` construct will generate a ``CREATE TABLE``
-    which only includes the ``id`` column in the string; the ``xmin`` column
-    will be omitted, but only against the Postgresql backend.
-
-    .. versionadded:: 0.8.3 The :class:`.CreateColumn` construct supports
-       skipping of columns by returning ``None`` from a custom compilation rule.
-
-    .. versionadded:: 0.8 The :class:`.CreateColumn` construct was added
-       to support custom column creation styles.

-        per-execution time formatting of the VALUES and/or SET clauses,
-        based on the arguments passed to :meth:`.Connection.execute`.  However,
-        the :meth:`.ValuesBase.values` method can be used to "fix" a particular
-        set of parameters into the statement.
-
-        Multiple calls to :meth:`.ValuesBase.values` will produce a new
-        construct, each one with the parameter list modified to include
-        the new parameters sent.  In the typical case of a single
-        dictionary of parameters, the newly passed keys will replace
-        the same keys in the previous construct.  In the case of a list-based
-        "multiple values" construct, each new list of values is extended
-        onto the existing list of values.

-
-                users.update().where(users.c.id==5).values(name="some name")
-
-        :param \*args: Alternatively, a dictionary, tuple or list
-         of dictionaries or tuples can be passed as a single positional
-         argument in order to form the VALUES or
-         SET clause of the statement.  The single dictionary form
-         works the same as the kwargs form::
-
-            users.insert().values({"name": "some name"})
-
-         If a tuple is passed, the tuple should contain the same number
-         of columns as the target :class:`.Table`::
-
-            users.insert().values((5, "some name"))
-
-         The :class:`.Insert` construct also supports multiply-rendered VALUES
-         construct, for those backends which support this SQL syntax
-         (SQLite, Postgresql, MySQL).  This mode is indicated by passing a list
-         of one or more dictionaries/tuples::
-
-            users.insert().values([
-                                {"name": "some name"},
-                                {"name": "some other name"},
-                                {"name": "yet another name"},
-                            ])
-
-         In the case of an :class:`.Update`
-         construct, only the single dictionary/tuple form is accepted,
-         else an exception is raised.  It is also an exception case to
-         attempt to mix the single-/multiple- value styles together,
-         either through multiple :meth:`.ValuesBase.values` calls
-         or by sending a list + kwargs at the same time.
-
-         .. note::
-
-             Passing a multiple values list is *not* the same
-             as passing a multiple values list to the :meth:`.Connection.execute`
-             method.  Passing a list of parameter sets to :meth:`.ValuesBase.values`
-             produces a construct of this form::
-
-                INSERT INTO table (col1, col2, col3) VALUES
-                                (col1_0, col2_0, col3_0),
-                                (col1_1, col2_1, col3_1),
-                                ...
-
-             whereas a multiple list passed to :meth:`.Connection.execute`
-             has the effect of using the DBAPI
-             `executemany() <http://www.python.org/dev/peps/pep-0249/#id18>`_
-             method, which provides a high-performance system of invoking
-             a single-row INSERT statement many times against a series
-             of parameter sets.   The "executemany" style is supported by
-             all database backends, as it does not depend on a special SQL
-             syntax.

-
-            result = connection.execute(stmt)
-
-            server_created_at = result.returned_defaults['created_at']
-
-        When used against a backend that supports RETURNING, all column
-        values generated by SQL expression or server-side-default will be added
-        to any existing RETURNING clause, provided that
-        :meth:`.UpdateBase.returning` is not used simultaneously.   The column values
-        will then be available on the result using the
-        :attr:`.ResultProxy.returned_defaults` accessor as a
-        dictionary, referring to values keyed to the :class:`.Column` object
-        as well as its ``.key``.
-
-        This method differs from :meth:`.UpdateBase.returning` in these ways:
-
-        1. :meth:`.ValuesBase.return_defaults` is only intended for use with
-           an INSERT or an UPDATE statement that matches exactly one row.
-           While the RETURNING construct in the general sense supports multiple
-           rows for a multi-row UPDATE or DELETE statement, or for special
-           cases of INSERT that return multiple rows (e.g. INSERT from SELECT,
-           multi-valued VALUES clause), :meth:`.ValuesBase.return_defaults`
-           is intended only
-           for an "ORM-style" single-row INSERT/UPDATE statement.  The row
-           returned by the statement is also consumed implcitly when
-           :meth:`.ValuesBase.return_defaults` is used.  By contrast,
-           :meth:`.UpdateBase.returning` leaves the RETURNING result-set intact
-           with a collection of any number of rows.
-
-        2. It is compatible with the existing logic to fetch auto-generated
-           primary key values, also known as "implicit returning".  Backends that
-           support RETURNING will automatically make use of RETURNING in order
-           to fetch the value of newly generated primary keys; while the
-           :meth:`.UpdateBase.returning` method circumvents this behavior,
-           :meth:`.ValuesBase.return_defaults` leaves it intact.
-
-        3. It can be called against any backend.  Backends that don't support
-           RETURNING will skip the usage of the feature, rather than raising
-           an exception.  The return value of :attr:`.ResultProxy.returned_defaults`
-           will be ``None``
-
-        :meth:`.ValuesBase.return_defaults` is used by the ORM to provide

-        :func:`.mapper`.

-        :class:`.Column`, normally but not necessarily equivalent to
-        its "name").  Normally, the
-        :class:`.Column` objects used here are expected to be
-        part of the target :class:`.Table` that is the table
-        to be updated.  However when using MySQL, a multiple-table
-        UPDATE statement can refer to columns from any of
-        the tables referred to in the WHERE clause.
-
-        The values referred to in ``values`` are typically:
-
-        * a literal data value (i.e. string, number, etc.)
-        * a SQL expression, such as a related :class:`.Column`,
-          a scalar-returning :func:`.select` construct,
-          etc.
-
-        When combining :func:`.select` constructs within the values
-        clause of an :func:`.update` construct,
-        the subquery represented by the :func:`.select` should be
-        *correlated* to the parent table, that is, providing criterion
-        which links the table inside the subquery to the outer table
-        being updated::
-
-            users.update().values(
-                    name=select([addresses.c.email_address]).\\
-                            where(addresses.c.user_id==users.c.id).\\
-                            as_scalar()
-                )

-    """Represent a column-oriented SQL expression suitable for usage in the
-    "columns" clause, WHERE clause etc. of a statement.
-
-    While the most familiar kind of :class:`.ColumnElement` is the
-    :class:`.Column` object, :class:`.ColumnElement` serves as the basis
-    for any unit that may be present in a SQL expression, including
-    the expressions themselves, SQL functions, bound parameters,
-    literal expressions, keywords such as ``NULL``, etc.
-    :class:`.ColumnElement` is the ultimate base class for all such elements.
-
-    A wide variety of SQLAlchemy Core functions work at the SQL expression level,
-    and are intended to accept instances of :class:`.ColumnElement` as arguments.
-    These functions will typically document that they accept a "SQL expression"
-    as an argument.  What this means in terms of SQLAlchemy usually refers
-    to an input which is either already in the form of a :class:`.ColumnElement`
-    object, or a value which can be **coerced** into one.   The coercion
-    rules followed by most, but not all, SQLAlchemy Core functions with regards
-    to SQL expressions are as follows:
-
-        * a literal Python value, such as a string, integer or floating
-          point value, boolean, datetime, ``Decimal`` object, or virtually
-          any other Python object, will be coerced into a "literal bound value".
-          This generally means that a :func:`.bindparam` will be produced
-          featuring the given value embedded into the construct; the resulting
-          :class:`.BindParameter` object is an instance of :class:`.ColumnElement`.
-          The Python value will ultimately be sent to the DBAPI at execution time as a
-          paramterized argument to the ``execute()`` or ``executemany()`` methods,
-          after SQLAlchemy type-specific converters (e.g. those provided by
-          any associated :class:`.TypeEngine` objects) are applied to the value.
-
-        * any special object value, typically ORM-level constructs, which feature
-          a method called ``__clause_element__()``.   The Core expression system
-          looks for this method when an object of otherwise unknown type is passed
-          to a function that is looking to coerce the argument into a :class:`.ColumnElement`
-          expression.  The ``__clause_element__()`` method, if present, should
-          return a :class:`.ColumnElement` instance.  The primary use of
-          ``__clause_element__()`` within SQLAlchemy is that of class-bound attributes
-          on ORM-mapped classes; a ``User`` class which contains a mapped attribute
-          named ``.name`` will have a method ``User.name.__clause_element__()``
-          which when invoked returns the :class:`.Column` called ``name`` associated
-          with the mapped table.
-
-        * The Python ``None`` value is typically interpreted as ``NULL``, which
-          in SQLAlchemy Core produces an instance of :func:`.null`.
-
-    A :class:`.ColumnElement` provides the ability to generate new
-    :class:`.ColumnElement`
-    objects using Python expressions.  This means that Python operators
-    such as ``==``, ``!=`` and ``<`` are overloaded to mimic SQL operations,
-    and allow the instantiation of further :class:`.ColumnElement` instances
-    which are composed from other, more fundamental :class:`.ColumnElement`
-    objects.  For example, two :class:`.ColumnClause` objects can be added
-    together with the addition operator ``+`` to produce
-    a :class:`.BinaryExpression`.
-    Both :class:`.ColumnClause` and :class:`.BinaryExpression` are subclasses
-    of :class:`.ColumnElement`::
-
-        >>> from sqlalchemy.sql import column
-        >>> column('a') + column('b')
-        <sqlalchemy.sql.expression.BinaryExpression object at 0x101029dd0>
-        >>> print column('a') + column('b')

-        at the point at which the statement in executed against a database
-        connection.
-
-        In SQLAlchemy, the :func:`.bindparam` construct has
-        the ability to carry along the actual value that will be ultimately
-        used at expression time.  In this way, it serves not just as
-        a "placeholder" for eventual population, but also as a means of
-        representing so-called "unsafe" values which should not be rendered
-        directly in a SQL statement, but rather should be passed along
-        to the :term:`DBAPI` as values which need to be correctly escaped
-        and potentially handled for type-safety.
-
-        When using :func:`.bindparam` explicitly, the use case is typically
-        one of traditional deferment of parameters; the :func:`.bindparam`
-        construct accepts a name which can then be referred to at execution
-        time::
-
-            from sqlalchemy import bindparam
-
-            stmt = select([users_table]).\\
-                        where(users_table.c.name == bindparam('username'))
-
-        The above statement, when rendered, will produce SQL similar to::
-
-            SELECT id, name FROM user WHERE name = :username
-
-        In order to populate the value of ``:username`` above, the value
-        would typically be applied at execution time to a method
-        like :meth:`.Connection.execute`::
-
-            result = connection.execute(stmt, username='wendy')
-
-        Explicit use of :func:`.bindparam` is also common when producing
-        UPDATE or DELETE statements that are to be invoked multiple times,
-        where the WHERE criterion of the statement is to change on each
-        invocation, such as::
-
-            stmt = users_table.update().\\
-                            where(user_table.c.name == bindparam('username')).\\
-                            values(fullname=bindparam('fullname'))
-
-            connection.execute(stmt, [
-                                {"username": "wendy", "fullname": "Wendy Smith"},
-                                {"username": "jack", "fullname": "Jack Jones"},
-                        ])
-
-        SQLAlchemy's Core expression system makes wide use of :func:`.bindparam`
-        in an implicit sense.   It is typical that Python literal values passed to
-        virtually all SQL expression functions are coerced into fixed
-        :func:`.bindparam` constructs.  For example, given a comparison operation
-        such as::
-
-            expr = users_table.c.name == 'Wendy'
-
-        The above expression will produce a :class:`.BinaryExpression`
-        contruct, where the left side is the :class:`.Column` object
-        representing the ``name`` column, and the right side is a :class:`.BindParameter`
-        representing the literal value::
-
-            print(repr(expr.right))
-            BindParameter('%(4327771088 name)s', 'Wendy', type_=String())
-
-        The expression above will render SQL such as::
-
-            user.name = :name_1
-
-        Where the ``:name_1`` parameter name is an anonymous name.  The
-        actual string ``Wendy`` is not in the rendered string, but is carried
-        along where it is later used within statement execution.  If we
-        invoke a statement like the following::
-
-            stmt = select([users_table]).where(users_table.c.name == 'Wendy')
-            result = connection.execute(stmt)
-
-        We would see SQL logging output as::
-
-            SELECT "user".id, "user".name
-            FROM "user"
-            WHERE "user".name = %(name_1)s
-            {'name_1': 'Wendy'}
-
-        Above, we see that ``Wendy`` is passed as a parameter to the database,
-        while the placeholder ``:name_1`` is rendered in the appropriate form
-        for the target database, in this case the Postgresql database.
-
-        Similarly, :func:`.bindparam` is invoked automatically
-        when working with :term:`CRUD` statements as far as the "VALUES"
-        portion is concerned.   The :func:`.insert` construct produces an
-        ``INSERT`` expression which will, at statement execution time, generate
-        bound placeholders based on the arguments passed, as in::
-
-            stmt = users_table.insert()
-            result = connection.execute(stmt, name='Wendy')
-
-        The above will produce SQL output as::
-
-            INSERT INTO "user" (name) VALUES (%(name)s)
-            {'name': 'Wendy'}
-
-        The :class:`.Insert` construct, at compilation/execution time,
-        rendered a single :func:`.bindparam` mirroring the column
-        name ``name`` as a result of the single ``name`` parameter
-        we passed to the :meth:`.Connection.execute` method.
-
-        :param key:
-          the key (e.g. the name) for this bind param.
-          Will be used in the generated
-          SQL statement for dialects that use named parameters.  This
-          value may be modified when part of a compilation operation,
-          if other :class:`BindParameter` objects exist with the same
-          key, or if its length is too long and truncation is
-          required.
-
-        :param value:
-          Initial value for this bind param.  Will be used at statement
-          execution time as the value for this parameter passed to the
-          DBAPI, if no other value is indicated to the statement execution
-          method for this particular parameter name.  Defaults to ``None``.
-
-        :param callable\_:
-          A callable function that takes the place of "value".  The function
-          will be called at statement execution time to determine the
-          ultimate value.   Used for scenarios where the actual bind
-          value cannot be determined at the point at which the clause
-          construct is created, but embedded bind values are still desirable.
-
-        :param type\_:
-          A :class:`.TypeEngine` class or instance representing an optional
-          datatype for this :func:`.bindparam`.  If not passed, a type
-          may be determined automatically for the bind, based on the given
-          value; for example, trivial Python types such as ``str``,
-          ``int``, ``bool``
-          may result in the :class:`.String`, :class:`.Integer` or
-          :class:`.Boolean` types being autoamtically selected.
-
-          The type of a :func:`.bindparam` is significant especially in that
-          the type will apply pre-processing to the value before it is
-          passed to the database.  For example, a :func:`.bindparam` which
-          refers to a datetime value, and is specified as holding the
-          :class:`.DateTime` type, may apply conversion needed to the
-          value (such as stringification on SQLite) before passing the value
-          to the database.
-
-        :param unique:
-          if True, the key name of this :class:`.BindParameter` will be
-          modified if another :class:`.BindParameter` of the same name
-          already has been located within the containing
-          expression.  This flag is used generally by the internals
-          when producing so-called "anonymous" bound expressions, it
-          isn't generally applicable to explicitly-named :func:`.bindparam`
-          constructs.
-
-        :param required:
-          If ``True``, a value is required at execution time.  If not passed,
-          it defaults to ``True`` if neither :paramref:`.bindparam.value`
-          or :paramref:`.bindparam.callable` were passed.  If either of these
-          parameters are present, then :paramref:`.bindparam.required` defaults
-          to ``False``.
-
-          .. versionchanged:: 0.8 If the ``required`` flag is not specified,
-             it will be set automatically to ``True`` or ``False`` depending
-             on whether or not the ``value`` or ``callable`` parameters
-             were specified.
-
-        :param quote:
-          True if this parameter name requires quoting and is not
-          currently known as a SQLAlchemy reserved word; this currently
-          only applies to the Oracle backend, where bound names must
-          sometimes be quoted.
-
-        :param isoutparam:
-          if True, the parameter should be treated like a stored procedure
-          "OUT" parameter.  This applies to backends such as Oracle which
-          support OUT parameters.

-
-            t = text("SELECT * FROM users")
-            result = connection.execute(t)
-
-        The advantages :func:`.text` provides over a plain string are
-        backend-neutral support for bind parameters, per-statement
-        execution options, as well as
-        bind parameter and result-column typing behavior, allowing
-        SQLAlchemy type constructs to play a role when executing
-        a statement that is specified literally.  The construct can also
-        be provided with a ``.c`` collection of column elements, allowing
-        it to be embedded in other SQL expression constructs as a subquery.
-
-        Bind parameters are specified by name, using the format ``:name``.
-        E.g.::
-
-            t = text("SELECT * FROM users WHERE id=:user_id")
-            result = connection.execute(t, user_id=12)
-
-        For SQL statements where a colon is required verbatim, as within
-        an inline string, use a backslash to escape::
-
-            t = text("SELECT * FROM users WHERE name='\\:username'")
-
-        The :class:`.TextClause` construct includes methods which can
-        provide information about the bound parameters as well as the column
-        values which would be returned from the textual statement, assuming
-        it's an executable SELECT type of statement.  The :meth:`.TextClause.bindparams`
-        method is used to provide bound parameter detail, and
-        :meth:`.TextClause.columns` method allows specification of
-        return columns including names and types::
-
-            t = text("SELECT * FROM users WHERE id=:user_id").\\
-                    bindparams(user_id=7).\\
-                    columns(id=Integer, name=String)
-
-            for id, name in connection.execute(t):
-                print(id, name)
-
-        The :func:`.text` construct is used internally in cases when
-        a literal string is specified for part of a larger query, such as
-        when a string is specified to the :meth:`.Select.where` method of
-        :class:`.Select`.  In those cases, the same
-        bind parameter syntax is applied::
-
-            s = select([users.c.id, users.c.name]).where("id=:user_id")
-            result = connection.execute(s, user_id=12)
-
-        Using :func:`.text` explicitly usually implies the construction
-        of a full, standalone statement.   As such, SQLAlchemy refers
-        to it as an :class:`.Executable` object, and it supports
-        the :meth:`Executable.execution_options` method.  For example,
-        a :func:`.text` construct that should be subject to "autocommit"
-        can be set explicitly so using the :paramref:`.Connection.execution_options.autocommit`
-        option::
-
-            t = text("EXEC my_procedural_thing()").\\
-                    execution_options(autocommit=True)
-
-        Note that SQLAlchemy's usual "autocommit" behavior applies to
-        :func:`.text` constructs implicitly - that is, statements which begin
-        with a phrase such as ``INSERT``, ``UPDATE``, ``DELETE``,
-        or a variety of other phrases specific to certain backends, will
-        be eligible for autocommit if no transaction is in progress.
-
-        :param text:
-          the text of the SQL statement to be created.  use ``:<param>``
-          to specify bind parameters; they will be compiled to their
-          engine-specific format.
-
-        :param autocommit:
-          Deprecated.  Use .execution_options(autocommit=<True|False>)

-        typing information, and a second time with value information, and it
-        will be combined::

-
-        When simple equality expressions of several values against a single
-        parent column are needed, :func:`.case` also has a "shorthand" format
-        used via the
-        :paramref:`.case.value` parameter, which is passed a column
-        expression to be compared.  In this form, the :paramref:`.case.whens`
-        parameter is passed as a dictionary containing expressions to be compared

-        :paramref:`.case.whens` as well as with :paramref:`.case.else_` are
-        coerced from Python literals into :func:`.bindparam` constructs.
-        SQL expressions, e.g. :class:`.ColumnElement` constructs, are accepted
-        as well.  To coerce a literal string expression into a constant
-        expression rendered inline, use the :func:`.literal_column` construct,
-        as in::
-
-            from sqlalchemy import case, literal_column

-        The above will render the given constants without using bound
-        parameters for the result values (but still for the comparison
-        values), as in::

-         accepts two different forms, based on whether or not :paramref:`.case.value`
-         is used.
-
-         In the first form, it accepts a list of 2-tuples; each 2-tuple consists
-         of ``(<sql expression>, <value>)``, where the SQL expression is a
-         boolean expression and "value" is a resulting value, e.g.::
-
-            case([
-                (users_table.c.name == 'wendy', 'W'),
-                (users_table.c.name == 'jack', 'J')
-            ])
-
-         In the second form, it accepts a Python dictionary of comparison values
-         mapped to a resulting value; this form requires :paramref:`.case.value`
-         to be present, and values will be compared using the ``==`` operator,
-         e.g.::
-
-            case(
-                {"wendy": "W", "jack": "J"},
-                value=users_table.c.name
-            )
-

-          fixed "comparison point" for candidate values within a dictionary
-          passed to :paramref:`.case.whens`.

-        The above statement would produce SQL like::
-
-            SELECT id, name FROM user
-
-        Once constructed, :func:`.column` may be used like any other SQL expression
-        element such as within :func:`.select` constructs::
-
-            from sqlalchemy.sql import column
-
-            id, name = column("id"), column("name")
-            stmt = select([id, name]).select_from("user")
-
-        The text handled by :func:`.column` is assumed to be handled
-        like the name of a database column; if the string contains mixed case,
-        special characters, or matches a known reserved word on the target
-        backend, the column expression will render using the quoting
-        behavior determined by the backend.  To produce a textual SQL
-        expression that is rendered exactly without any quoting,
-        use :func:`.literal_column` instead, or pass ``True`` as the
-        value of :paramref:`.column.is_literal`.   Additionally, full SQL
-        statements are best handled using the :func:`.text` construct.
-
-        :func:`.column` can be used in a table-like
-        fashion by combining it with the :func:`.table` function
-        (which is the lightweight analogue to :class:`.Table`) to produce
-        a working table construct with minimal boilerplate::
-
-            from sqlalchemy.sql import table, column
-
-            user = table("user",
-                    column("id"),
-                    column("name"),
-                    column("description"),
-            )
-
-            stmt = select([user.c.description]).where(user.c.name == 'wendy')
-
-        A :func:`.column` / :func:`.table` construct like that illustrated
-        above can be created in an
-        ad-hoc fashion and is not associated with any :class:`.schema.MetaData`,
-        DDL, or events, unlike its :class:`.Table` counterpart.
-
-        :param text: the text of the element.
-
-        :param type: :class:`.types.TypeEngine` object which can associate
-          this :class:`.ColumnClause` with a type.
-
-        :param is_literal: if True, the :class:`.ColumnClause` is assumed to
-          be an exact expression that will be delivered to the output with no
-          quoting rules applied regardless of case sensitive settings. the
-          :func:`.literal_column()` function essentially invokes :func:`.column`
-          while passing ``is_literal=True``.
-
-        .. seealso::

-            :class:`.Column`

-
-    :class:`.quoted_name` is a Python unicode/str subclass which
-    represents a particular identifier name along with a
-    ``quote`` flag.  This ``quote`` flag, when set to
-    ``True`` or ``False``, overrides automatic quoting behavior
-    for this identifier in order to either unconditionally quote
-    or to not quote the name.  If left at its default of ``None``,
-    quoting behavior is applied to the identifier on a per-backend basis
-    based on an examination of the token itself.
-
-    A :class:`.quoted_name` object with ``quote=True`` is also
-    prevented from being modified in the case of a so-called
-    "name normalize" option.  Certain database backends, such as
-    Oracle, Firebird, and DB2 "normalize" case-insensitive names
-    as uppercase.  The SQLAlchemy dialects for these backends
-    convert from SQLAlchemy's lower-case-means-insensitive convention
-    to the upper-case-means-insensitive conventions of those backends.
-    The ``quote=True`` flag here will prevent this conversion from occurring
-    to support an identifier that's quoted as all lower case against
-    such a backend.
-
-    The :class:`.quoted_name` object is normally created automatically
-    when specifying the name for key schema constructs such as :class:`.Table`,
-    :class:`.Column`, and others.   The class can also be passed explicitly
-    as the name to any function that receives a name which can be quoted.
-    Such as to use the :meth:`.Engine.has_table` method with an unconditionally
-    quoted name::
-
-        from sqlaclchemy import create_engine
-        from sqlalchemy.sql.elements import quoted_name
-
-        engine = create_engine("oracle+cx_oracle://some_dsn")
-        engine.has_table(quoted_name("some_table", True))
-
-    The above logic will run the "has table" logic against the Oracle backend,
-    passing the name exactly as ``"some_table"`` without converting to
-    upper case.

-
-   :data:`.func` is a special object instance which generates SQL
-   functions based on name-based attributes, e.g.::
-
-        >>> print func.count(1)
-        count(:param_1)
-
-   The element is a column-oriented SQL element like any other, and is
-   used in that way::
-
-        >>> print select([func.count(table.c.id)])
-        SELECT count(sometable.id) FROM sometable
-
-   Any name can be given to :data:`.func`. If the function name is unknown to
-   SQLAlchemy, it will be rendered exactly as is. For common SQL functions
-   which SQLAlchemy is aware of, the name may be interpreted as a *generic
-   function* which will be compiled appropriately to the target database::
-
-        >>> print func.current_timestamp()
-        CURRENT_TIMESTAMP
-
-   To call functions which are present in dot-separated packages,
-   specify them in the same manner::
-
-        >>> print func.stats.yield_curve(5, 10)
-        stats.yield_curve(:yield_curve_1, :yield_curve_2)
-
-   SQLAlchemy can be made aware of the return type of functions to enable
-   type-specific lexical and result-based behavior. For example, to ensure
-   that a string-based function returns a Unicode value and is similarly
-   treated as a string in expressions, specify
-   :class:`~sqlalchemy.types.Unicode` as the type:
-
-        >>> print func.my_string(u'hi', type_=Unicode) + ' ' + \
-        ... func.my_string(u'there', type_=Unicode)
-        my_string(:my_string_1) || :my_string_2 || my_string(:my_string_3)
-
-   The object returned by a :data:`.func` call is usually an instance of
-   :class:`.Function`.
-   This object meets the "column" interface, including comparison and labeling
-   functions.  The object can also be passed the :meth:`~.Connectable.execute`
-   method of a :class:`.Connection` or :class:`.Engine`, where it will be
-   wrapped inside of a SELECT statement first::
-
-        print connection.execute(func.current_timestamp()).scalar()
-
-   In a few exception cases, the :data:`.func` accessor
-   will redirect a name to a built-in expression such as :func:`.cast`
-   or :func:`.extract`, as these names have well-known meaning
-   but are not exactly the same as "functions" from a SQLAlchemy
-   perspective.
-
-   .. versionadded:: 0.8 :data:`.func` can return non-function expression
-      constructs for common quasi-functional names like :func:`.cast`
-      and :func:`.extract`.

-   calculate their return type automatically. For a listing of known generic

-
-    User-defined generic functions can be organized into
-    packages by specifying the "package" attribute when defining
-    :class:`.GenericFunction`.   Third party libraries
-    containing many functions may want to use this in order
-    to avoid name conflicts with other systems.   For example,
-    if our ``as_utc()`` function were part of a package
-    "time"::
-
-        class as_utc(GenericFunction):
-            type = DateTime
-            package = "time"
-
-    The above function would be available from :data:`.func`
-    using the package name ``time``::
-
-        print select([func.time.as_utc()])
-
-    A final option is to allow the function to be accessed
-    from one name in :data:`.func` but to render as a different name.
-    The ``identifier`` attribute will override the name used to
-    access the function as loaded from :data:`.func`, but will retain
-    the usage of ``name`` as the rendered name::
-
-        class GeoBuffer(GenericFunction):
-            type = Geometry
-            package = "geo"
-            name = "ST_Buffer"
-            identifier = "buffer"
-
-    The above function will render as follows::
-
-        >>> print func.geo.buffer()
-        ST_Buffer()
-
-    .. versionadded:: 0.8 :class:`.GenericFunction` now supports
-       automatic registration of new functions as well as package
-       and custom naming support.
-
-    .. versionchanged:: 0.8 The attribute name ``type`` is used
-       to specify the function's return type at the class level.
-       Previously, the name ``__return_type__`` was used.  This
-       name is still recognized for backwards-compatibility.

-
-    In some situations, such as in migration scripts, we may be rendering

-"""The schema module provides the building blocks for database metadata.
-
-Each element within this module describes a database entity which can be
-created and dropped, or is otherwise part of such an entity.  Examples include
-tables, columns, sequences, and indexes.
-
-All entities are subclasses of :class:`~sqlalchemy.schema.SchemaItem`, and as
-defined in this module they are intended to be agnostic of any vendor-specific
-constructs.
-
-A collection of entities are grouped into a unit called
-:class:`~sqlalchemy.schema.MetaData`. MetaData serves as a logical grouping of
-schema elements, and can also be associated with an actual database connection
-such that operations involving the contained elements can contact the database
-as needed.
-
-Two of the elements here also build upon their "syntactic" counterparts, which
-are defined in :class:`~sqlalchemy.sql.expression.`, specifically
-:class:`~sqlalchemy.schema.Table` and :class:`~sqlalchemy.schema.Column`.
-Since these objects are part of the SQL expression language, they are usable
-as components in SQL expressions.

-
-    The :class:`.Table` object constructs a unique instance of itself based
-    on its name and optional schema name within the given
-    :class:`.MetaData` object. Calling the :class:`.Table`
-    constructor with the same name and same :class:`.MetaData` argument
-    a second time will return the *same* :class:`.Table` object - in this way
-    the :class:`.Table` constructor acts as a registry function.
-
-    .. seealso::
-
-        :ref:`metadata_describing` - Introduction to database metadata
-
-    Constructor arguments are as follows:
-
-    :param name: The name of this table as represented in the database.
-
-        The table name, along with the value of the ``schema`` parameter,
-        forms a key which uniquely identifies this :class:`.Table` within
-        the owning :class:`.MetaData` collection.
-        Additional calls to :class:`.Table` with the same name, metadata,
-        and schema name will return the same :class:`.Table` object.
-
-        Names which contain no upper case characters
-        will be treated as case insensitive names, and will not be quoted
-        unless they are a reserved word or contain special characters.
-        A name with any number of upper case characters is considered
-        to be case sensitive, and will be sent as quoted.
-
-        To enable unconditional quoting for the table name, specify the flag
-        ``quote=True`` to the constructor, or use the :class:`.quoted_name`
-        construct to specify the name.
-
-    :param metadata: a :class:`.MetaData` object which will contain this
-        table.  The metadata is used as a point of association of this table
-        with other tables which are referenced via foreign key.  It also
-        may be used to associate this table with a particular
-        :class:`.Connectable`.
-
-    :param \*args: Additional positional arguments are used primarily
-        to add the list of :class:`.Column` objects contained within this
-        table. Similar to the style of a CREATE TABLE statement, other
-        :class:`.SchemaItem` constructs may be added here, including
-        :class:`.PrimaryKeyConstraint`, and :class:`.ForeignKeyConstraint`.
-
-    :param autoload: Defaults to False: the Columns for this table should
-        be reflected from the database. Usually there will be no Column
-        objects in the constructor if this property is set.
-
-    :param autoload_replace: If ``True``, when using ``autoload=True``
-        and ``extend_existing=True``,
-        replace ``Column`` objects already present in the ``Table`` that's
-        in the ``MetaData`` registry with
-        what's reflected.  Otherwise, all existing columns will be
-        excluded from the reflection process.    Note that this does
-        not impact ``Column`` objects specified in the same call to ``Table``
-        which includes ``autoload``, those always take precedence.
-        Defaults to ``True``.
-
-        .. versionadded:: 0.7.5
-
-    :param autoload_with: If autoload==True, this is an optional Engine
-        or Connection instance to be used for the table reflection. If
-        ``None``, the underlying MetaData's bound connectable will be used.
-
-    :param extend_existing: When ``True``, indicates that if this
-        :class:`.Table` is already present in the given :class:`.MetaData`,
-        apply further arguments within the constructor to the existing
-        :class:`.Table`.
-
-        If ``extend_existing`` or ``keep_existing`` are not set, an error is
-        raised if additional table modifiers are specified when
-        the given :class:`.Table` is already present in the :class:`.MetaData`.
-
-        .. versionchanged:: 0.7.4
-            ``extend_existing`` will work in conjunction
-            with ``autoload=True`` to run a new reflection operation against
-            the database; new :class:`.Column` objects will be produced
-            from database metadata to replace those existing with the same
-            name, and additional :class:`.Column` objects not present
-            in the :class:`.Table` will be added.
-
-        As is always the case with ``autoload=True``, :class:`.Column`
-        objects can be specified in the same :class:`.Table` constructor,
-        which will take precedence.  I.e.::
-
-            Table("mytable", metadata,
-                        Column('y', Integer),
-                        extend_existing=True,
-                        autoload=True,
-                        autoload_with=engine
-                    )
-
-        The above will overwrite all columns within ``mytable`` which
-        are present in the database, except for ``y`` which will be used as is
-        from the above definition.   If the ``autoload_replace`` flag
-        is set to False, no existing columns will be replaced.
-
-    :param implicit_returning: True by default - indicates that
-        RETURNING can be used by default to fetch newly inserted primary key
-        values, for backends which support this.  Note that
-        create_engine() also provides an implicit_returning flag.
-
-    :param include_columns: A list of strings indicating a subset of
-        columns to be loaded via the ``autoload`` operation; table columns who
-        aren't present in this list will not be represented on the resulting
-        ``Table`` object. Defaults to ``None`` which indicates all columns
-        should be reflected.
-
-    :param info: Optional data dictionary which will be populated into the
-        :attr:`.SchemaItem.info` attribute of this object.
-
-    :param keep_existing: When ``True``, indicates that if this Table
-        is already present in the given :class:`.MetaData`, ignore
-        further arguments within the constructor to the existing
-        :class:`.Table`, and return the :class:`.Table` object as
-        originally created. This is to allow a function that wishes
-        to define a new :class:`.Table` on first call, but on
-        subsequent calls will return the same :class:`.Table`,
-        without any of the declarations (particularly constraints)
-        being applied a second time. Also see extend_existing.
-
-        If extend_existing or keep_existing are not set, an error is
-        raised if additional table modifiers are specified when
-        the given :class:`.Table` is already present in the :class:`.MetaData`.
-
-    :param listeners: A list of tuples of the form ``(<eventname>, <fn>)``
-        which will be passed to :func:`.event.listen` upon construction.
-        This alternate hook to :func:`.event.listen` allows the establishment
-        of a listener function specific to this :class:`.Table` before
-        the "autoload" process begins.  Particularly useful for
-        the :meth:`.DDLEvents.column_reflect` event::
-
-            def listen_for_reflect(table, column_info):
-                "handle the column reflection event"
-                # ...
-
-            t = Table(
-                'sometable',
-                autoload=True,
-                listeners=[
-                    ('column_reflect', listen_for_reflect)
-                ])
-
-    :param mustexist: When ``True``, indicates that this Table must already
-        be present in the given :class:`.MetaData` collection, else
-        an exception is raised.
-
-    :param prefixes:
-        A list of strings to insert after CREATE in the CREATE TABLE
-        statement.  They will be separated by spaces.
-
-    :param quote: Force quoting of this table's name on or off, corresponding
-        to ``True`` or ``False``.  When left at its default of ``None``,
-        the column identifier will be quoted according to whether the name is
-        case sensitive (identifiers with at least one upper case character are
-        treated as case sensitive), or if it's a reserved word.  This flag
-        is only needed to force quoting of a reserved word which is not known
-        by the SQLAlchemy dialect.
-
-    :param quote_schema: same as 'quote' but applies to the schema identifier.
-
-    :param schema: The schema name for this table, which is required if
-        the table resides in a schema other than the default selected schema
-        for the engine's database connection.  Defaults to ``None``.
-
-        The quoting rules for the schema name are the same as those for the
-        ``name`` parameter, in that quoting is applied for reserved words or
-        case-sensitive names; to enable unconditional quoting for the
-        schema name, specify the flag
-        ``quote_schema=True`` to the constructor, or use the :class:`.quoted_name`
-        construct to specify the name.
-
-    :param useexisting: Deprecated.  Use extend_existing.
-
-    :param \**kw: Additional keyword arguments not mentioned above are
-        dialect specific, and passed in the form ``<dialectname>_<argname>``.
-        See the documentation regarding an individual dialect at
-        :ref:`dialect_toplevel` for detail on documented arguments.

-          as options to the column.  These include instances of
-          :class:`.Constraint`, :class:`.ForeignKey`, :class:`.ColumnDefault`,
-          and :class:`.Sequence`.  In some cases an equivalent keyword
-          argument is available such as ``server_default``, ``default``
-          and ``unique``.
-

-          the integer primary key column which generates values
-          implicitly upon INSERT and whose value is usually returned
-          via the DBAPI cursor.lastrowid attribute.   It defaults
-          to ``True`` to satisfy the common use case of a table
-          with a single integer primary key column.  If the table
-          has a composite primary key consisting of more than one
-          integer column, set this flag to True only on the

-
-          The setting *only* has an effect for columns which are:
-
-          * Integer derived (i.e. INT, SMALLINT, BIGINT).
-
-          * Part of the primary key
-

-
-          * have no server side or client side defaults (with the exception
-            of Postgresql SERIAL).
-
-          The setting has these two effects on columns that meet the
-          above criteria:
-
-          * DDL issued for the column will include database-specific
-            keywords intended to signify this column as an
-            "autoincrement" column, such as AUTO INCREMENT on MySQL,
-            SERIAL on Postgresql, and IDENTITY on MS-SQL.  It does
-            *not* issue AUTOINCREMENT for SQLite since this is a
-            special SQLite flag that is not required for autoincrementing
-            behavior.  See the SQLite dialect documentation for
-            information on SQLite's AUTOINCREMENT.
-
-          * The column will be considered to be available as
-            cursor.lastrowid or equivalent, for those dialects which
-            "post fetch" newly inserted identifiers after a row has
-            been inserted (SQLite, MySQL, MS-SQL).  It does not have
-            any effect in this regard for databases that use sequences
-            to generate primary key identifiers (i.e. Firebird, Postgresql,
-            Oracle).
-
-          .. versionchanged:: 0.7.4
-              ``autoincrement`` accepts a special value ``'ignore_fk'``
-              to indicate that autoincrementing status regardless of foreign
-              key references.  This applies to certain composite foreign key
-              setups, such as the one demonstrated in the ORM documentation
-              at :ref:`post_update`.
-
-        :param default: A scalar, Python callable, or
-            :class:`.ColumnElement` expression representing the
-            *default value* for this column, which will be invoked upon insert
-            if this column is otherwise not specified in the VALUES clause of
-            the insert. This is a shortcut to using :class:`.ColumnDefault` as
-            a positional argument; see that class for full detail on the
-            structure of the argument.
-
-            Contrast this argument to ``server_default`` which creates a
-            default generator on the database side.
-
-        :param doc: optional String that can be used by the ORM or similar
-            to document attributes.   This attribute does not render SQL
-            comments (a future attribute 'comment' will achieve that).
-
-        :param key: An optional string identifier which will identify this
-            ``Column`` object on the :class:`.Table`. When a key is provided,
-            this is the only identifier referencing the ``Column`` within the
-            application, including ORM attribute mapping; the ``name`` field
-            is used only when rendering SQL.
-
-        :param index: When ``True``, indicates that the column is indexed.
-            This is a shortcut for using a :class:`.Index` construct on the
-            table. To specify indexes with explicit names or indexes that
-            contain multiple columns, use the :class:`.Index` construct
-            instead.
-
-        :param info: Optional data dictionary which will be populated into the
-            :attr:`.SchemaItem.info` attribute of this object.
-
-        :param nullable: If set to the default of ``True``, indicates the
-            column will be rendered as allowing NULL, else it's rendered as
-            NOT NULL. This parameter is only used when issuing CREATE TABLE
-            statements.
-
-        :param onupdate: A scalar, Python callable, or
-            :class:`~sqlalchemy.sql.expression.ClauseElement` representing a
-            default value to be applied to the column within UPDATE
-            statements, which wil be invoked upon update if this column is not
-            present in the SET clause of the update. This is a shortcut to
-            using :class:`.ColumnDefault` as a positional argument with
-            ``for_update=True``.
-
-        :param primary_key: If ``True``, marks this column as a primary key
-            column. Multiple columns can have this flag set to specify
-            composite primary keys. As an alternative, the primary key of a
-            :class:`.Table` can be specified via an explicit
-            :class:`.PrimaryKeyConstraint` object.
-
-        :param server_default: A :class:`.FetchedValue` instance, str, Unicode
-            or :func:`~sqlalchemy.sql.expression.text` construct representing
-            the DDL DEFAULT value for the column.
-

-                Column('x', Text, server_default="val")

-            object upon initialization.

-            column will generate a default value on the database side which
-            will be available to SQLAlchemy for post-fetch after inserts. This
-            construct does not specify any DDL and the implementation is left
-            to the database, such as via a trigger.
-

-             representing a database-side default generation function. This

-             available after updates. This construct does not specify any DDL
-             and the implementation is left to the database, such as via a
-             trigger.
-
-        :param quote: Force quoting of this column's name on or off,
-             corresponding to ``True`` or ``False``. When left at its default
-             of ``None``, the column identifier will be quoted according to
-             whether the name is case sensitive (identifiers with at least one
-             upper case character are treated as case sensitive), or if it's a
-             reserved word. This flag is only needed to force quoting of a
-             reserved word which is not known by the SQLAlchemy dialect.
-
-        :param unique: When ``True``, indicates that this column contains a
-             unique constraint, or if ``index`` is ``True`` as well, indicates
-             that the :class:`.Index` should be created with the unique flag.
-             To specify multiple columns in the constraint/index or to specify
-             an explicit name, use the :class:`.UniqueConstraint` or
-             :class:`.Index` constructs explicitly.
-
-        :param system: When ``True``, indicates this is a "system" column,
-             that is a column which is automatically made available by the
-             database, and should not be included in the columns list for a
-             ``CREATE TABLE`` statement.
-
-             For more elaborate scenarios where columns should be conditionally
-             rendered differently on different backends, consider custom
-             compilation rules for :class:`.CreateColumn`.

-            :class:`.ForeignKeyConstraint` class, the :class:`.Index` class
-
-          * a string mnemonic for one of the known constraint classes;
-            ``"fk"``, ``"pk"``, ``"ix"``, ``"ck"``, ``"uq"`` for foreign key,
-            primary key, index, check, and unique constraint, respectively.
-
-          * the string name of a user-defined "token" that can be used
-            to define new naming tokens.
-
-          The values associated with each "constraint class" or "constraint
-          mnemonic" key are string naming templates, such as
-          ``"uq_%(table_name)s_%(column_0_name)s"``,
-          which decribe how the name should be composed.  The values associated
-          with user-defined "token" keys should be callables of the form
-          ``fn(constraint, table)``, which accepts the constraint/index
-          object and :class:`.Table` as arguments, returning a string
-          result.
-
-          The built-in names are as follows, some of which may only be
-          available for certain types of constraint:
-
-            * ``%(table_name)s`` - the name of the :class:`.Table` object
-              associated with the constraint.
-
-            * ``%(referred_table_name)s`` - the name of the :class:`.Table`
-              object associated with the referencing target of a
-              :class:`.ForeignKeyConstraint`.
-
-            * ``%(column_0_name)s`` - the name of the :class:`.Column` at
-              index position "0" within the constraint.
-
-            * ``%(column_0_label)s`` - the label of the :class:`.Column` at
-              index position "0", e.g. :attr:`.Column.label`
-
-            * ``%(column_0_key)s`` - the key of the :class:`.Column` at
-              index position "0", e.g. :attr:`.Column.key`
-
-            * ``%(referred_column_0_name)s`` - the name of a :class:`.Column`
-              at index position "0" referenced by a :class:`.ForeignKeyConstraint`.
-
-            * ``%(constraint_name)s`` - a special key that refers to the existing
-              name given to the constraint.  When this key is present, the
-              :class:`.Constraint` object's existing name will be replaced with
-              one that is composed from template string that uses this token.
-              When this token is present, it is required that the :class:`.Constraint`
-              is given an expicit name ahead of time.
-
-            * user-defined: any additional token may be implemented by passing

-                FROM table_a
-                JOIN table_b ON table_a.id = table_b.a_id) AS anon_1

-            j = alias(
-                select([j.left, j.right]).\\

-                    correlate(False),
-                name=name
-            )
-
-        The selectable produced by :meth:`.Join.alias` features the same
-        columns as that of the two individual selectables presented under
-        a single name - the individual columns are "auto-labeled", meaning
-        the ``.c.`` collection of the resulting :class:`.Alias` represents
-        the names of the individual columns using a ``<tablename>_<columname>``
-        scheme::
-
-            j.c.table_a_id
-            j.c.table_b_a_id
-
-        :meth:`.Join.alias` also features an alternate
-        option for aliasing joins which produces no enclosing SELECT and
-        does not normally apply labels to the column names.  The
-        ``flat=True`` option will call :meth:`.FromClause.alias`
-        against the left and right sides individually.
-        Using this option, no new ``SELECT`` is produced;
-        we instead, from a construct as below::
-
-            j = table_a.join(table_b, table_a.c.id == table_b.c.a_id)
-            j = j.alias(flat=True)
-
-        we get a result like this::
-
-            table_a AS table_a_1 JOIN table_b AS table_b_1 ON
-            table_a_1.id = table_b_1.a_id
-
-        The ``flat=True`` argument is also propagated to the contained
-        selectables, so that a composite join such as::
-
-            j = table_a.join(
-                    table_b.join(table_c,
-                            table_b.c.id == table_c.c.b_id),
-                    table_b.c.a_id == table_a.c.id
-                ).alias(flat=True)
-
-        Will produce an expression like::
-
-            table_a AS table_a_1 JOIN (
-                    table_b AS table_b_1 JOIN table_c AS table_c_1
-                    ON table_b_1.id = table_c_1.b_id
-            ) ON table_a_1.id = table_b_1.a_id
-
-        The standalone :func:`~.expression.alias` function as well as the
-        base :meth:`.FromClause.alias` method also support the ``flat=True``
-        argument as a no-op, so that the argument can be passed to the
-        ``alias()`` method of any selectable.

-        .. versionadded:: 0.9.0 Added the ``flat=True`` option to create

-            Due to a bug fix, this method has a slight
-            behavioral change as of version 0.7.3.
-            Prior to version 0.7.3, the FROM clause of
-            a :func:`.select` was calculated upfront and as new columns
-            were added; in 0.7.3 and later it's calculated
-            at compile time, fixing an issue regarding late binding
-            of columns to parent tables.  This changes the behavior of
-            :meth:`.Select.with_only_columns` in that FROM clauses no
-            longer represented in the new list are dropped,
-            but this behavior is more consistent in
-            that the FROM clauses are consistently derived from the
-            current columns clause.  The original intent of this method
-            is to allow trimming of the existing columns list to be fewer
-            columns than originally present; the use case of replacing
-            the columns list with an entirely different one hadn't
-            been anticipated until 0.7.3 was released; the usage
-            guidelines below illustrate how this should be done.
-
-        This method is exactly equivalent to as if the original
-        :func:`.select` had been called with the given columns
-        clause.   I.e. a statement::
-
-            s = select([table1.c.a, table1.c.b])
-            s = s.with_only_columns([table1.c.b])
-
-        should be exactly equivalent to::
-
-            s = select([table1.c.b])
-
-        This means that FROM clauses which are only derived
-        from the column list will be discarded if the new column
-        list no longer contains that FROM::
-
-            >>> table1 = table('t1', column('a'), column('b'))
-            >>> table2 = table('t2', column('a'), column('b'))
-            >>> s1 = select([table1.c.a, table2.c.b])
-            >>> print s1
-            SELECT t1.a, t2.b FROM t1, t2
-            >>> s2 = s1.with_only_columns([table2.c.b])
-            >>> print s2
-            SELECT t2.b FROM t1
-
-        The preferred way to maintain a specific FROM clause
-        in the construct, assuming it won't be represented anywhere
-        else (i.e. not in the WHERE clause, etc.) is to set it using
-        :meth:`.Select.select_from`::
-
-            >>> s1 = select([table1.c.a, table2.c.b]).\\
-            ...         select_from(table1.join(table2,
-            ...                 table1.c.a==table2.c.a))
-            >>> s2 = s1.with_only_columns([table2.c.b])
-            >>> print s2
-            SELECT t2.b FROM t1 JOIN t2 ON t1.a=t2.a
-
-        Care should also be taken to use the correct
-        set of column objects passed to :meth:`.Select.with_only_columns`.
-        Since the method is essentially equivalent to calling the
-        :func:`.select` construct in the first place with the given
-        columns, the columns passed to :meth:`.Select.with_only_columns`
-        should usually be a subset of those which were passed
-        to the :func:`.select` construct, not those which are available
-        from the ``.c`` collection of that :func:`.select`.  That
-        is::
-
-            s = select([table1.c.a, table1.c.b]).select_from(table1)
-            s = s.with_only_columns([table1.c.b])
-
-        and **not**::
-
-            # usually incorrect
-            s = s.with_only_columns([s.c.b])
-
-        The latter would produce the SQL::
-
-            SELECT b
-            FROM (SELECT t1.a AS a, t1.b AS b
-            FROM t1), t1
-
-        Since the :func:`.select` construct is essentially being
-        asked to select both from ``table1`` as well as itself.

-        :term:`columns clause` will be omitted from this :class:`.Select`
-        object's :term:`FROM clause`.
-        Setting an explicit correlation collection using the
-        :meth:`.Select.correlate` method provides a fixed list of FROM objects
-        that can potentially take place in this process.
-
-        When :meth:`.Select.correlate` is used to apply specific FROM clauses
-        for correlation, the FROM elements become candidates for
-        correlation regardless of how deeply nested this :class:`.Select`
-        object is, relative to an enclosing :class:`.Select` which refers to
-        the same FROM object.  This is in contrast to the behavior of
-        "auto-correlation" which only correlates to an immediate enclosing
-        :class:`.Select`.   Multi-level correlation ensures that the link
-        between enclosed and enclosing :class:`.Select` is always via
-        at least one WHERE/ORDER BY/HAVING/columns clause in order for
-        correlation to take place.
-
-        If ``None`` is passed, the :class:`.Select` object will correlate
-        none of its FROM entries, and all will render unconditionally
-        in the local FROM clause.

-           located in an enclosing :class:`.Select`, which ultimately encloses

-    and in that regard is equivalent to the usage of the
-    ``convert_unicode`` flag with the :class:`.String` type.
-    However, unlike plain :class:`.String`, it also implies an
-    underlying column type that is explicitly supporting of non-ASCII
-    data, such as ``NVARCHAR`` on Oracle and SQL Server.
-    This can impact the output of ``CREATE TABLE`` statements
-    and ``CAST`` functions at the dialect level, and can
-    also affect the handling of bound parameters in some
-    specific DBAPI scenarios.
-
-    The encoding used by the :class:`.Unicode` type is usually
-    determined by the DBAPI itself; most modern DBAPIs
-    feature support for Python ``unicode`` objects as bound
-    values and result set values, and the encoding should
-    be configured as detailed in the notes for the target
-    DBAPI in the :ref:`dialect_toplevel` section.
-
-    For those DBAPIs which do not support, or are not configured
-    to accommodate Python ``unicode`` objects
-    directly, SQLAlchemy does the encoding and decoding
-    outside of the DBAPI.   The encoding in this scenario
-    is determined by the ``encoding`` flag passed to
-    :func:`.create_engine`.
-
-    When using the :class:`.Unicode` type, it is only appropriate
-    to pass Python ``unicode`` objects, and not plain ``str``.
-    If a plain ``str`` is passed under Python 2, a warning
-    is emitted.  If you notice your application emitting these warnings but
-    you're not sure of the source of them, the Python
-    ``warnings`` filter, documented at
-    http://docs.python.org/library/warnings.html,
-    can be used to turn these warnings into exceptions

-
-    For an application that wishes to pass plain bytestrings
-    and Python ``unicode`` objects to the ``Unicode`` type
-    equally, the bytestrings must first be decoded into

-           object. For types that exist on the target database as an
-           independent schema construct (Postgresql), this type will be
-           created and dropped within ``create_all()`` and ``drop_all()``
-           operations. If the type is not associated with any ``MetaData``

-           used, and will be created when any of those individual tables are
-           created, after a check is performed for it's existence. The type is
-           only dropped when ``drop_all()`` is called for that ``Table``
-           object's metadata, however.
-
-        :param name: The name of this type. This is required for Postgresql
-           and any future supported database which requires an explicitly
-           named type, or an explicitly named constraint in order to generate
-           the type and/or a table that uses it.
-
-        :param native_enum: Use the database's native ENUM type when
-           available. Defaults to True. When False, uses VARCHAR + check

-
-        :param schema: Schema name of this type. For types that exist on the
-           target database as an independent schema construct (Postgresql),
-           this parameter specifies the named schema in which the type is
-           present.

-
-                The ``schema`` of the :class:`.Enum` type does not
-                by default make use of the ``schema`` established on the
-                owning :class:`.Table`.  If this behavior is desired,
-                set the ``inherit_schema`` flag to ``True``.
-
-        :param quote: Set explicit quoting preferences for the type's name.
-
-        :param inherit_schema: When ``True``, the "schema" from the owning

-           :class:`.Enum`, replacing whatever value was passed for the
-           ``schema`` attribute.   This also takes effect when using the

-    to an existing type.
-
-    This method is preferred to direct subclassing of SQLAlchemy's
-    built-in types as it ensures that all required functionality of
-    the underlying type is kept in place.
-
-    Typical usage::
-
-      import sqlalchemy.types as types
-
-      class MyType(types.TypeDecorator):
-          '''Prefixes Unicode values with "PREFIX:" on the way in and
-          strips it off on the way out.
-          '''
-
-          impl = types.Unicode
-
-          def process_bind_param(self, value, dialect):
-              return "PREFIX:" + value
-
-          def process_result_value(self, value, dialect):
-              return value[7:]
-
-          def copy(self):
-              return MyType(self.impl.length)
-
-    The class-level "impl" attribute is required, and can reference any
-    TypeEngine class.  Alternatively, the load_dialect_impl() method
-    can be used to provide different type classes based on the dialect
-    given; in this case, the "impl" variable can reference
-    ``TypeEngine`` as a placeholder.
-
-    Types that receive a Python type that isn't similar to the ultimate type
-    used may want to define the :meth:`TypeDecorator.coerce_compared_value`
-    method. This is used to give the expression system a hint when coercing
-    Python objects into bind parameters within expressions. Consider this
-    expression::
-
-        mytable.c.somecol + datetime.date(2009, 5, 15)
-
-    Above, if "somecol" is an ``Integer`` variant, it makes sense that
-    we're doing date arithmetic, where above is usually interpreted
-    by databases as adding a number of days to the given date.
-    The expression system does the right thing by not attempting to
-    coerce the "date()" value into an integer-oriented bind parameter.
-
-    However, in the case of ``TypeDecorator``, we are usually changing an
-    incoming Python type to something new - ``TypeDecorator`` by default will
-    "coerce" the non-typed side to be the same type as itself. Such as below,
-    we define an "epoch" type that stores a date value as an integer::
-
-        class MyEpochType(types.TypeDecorator):
-            impl = types.Integer
-
-            epoch = datetime.date(1970, 1, 1)
-
-            def process_bind_param(self, value, dialect):
-                return (value - self.epoch).days
-
-            def process_result_value(self, value, dialect):
-                return self.epoch + timedelta(days=value)
-
-    Our expression of ``somecol + date`` with the above type will coerce the
-    "date" on the right side to also be treated as ``MyEpochType``.
-
-    This behavior can be overridden via the
-    :meth:`~TypeDecorator.coerce_compared_value` method, which returns a type
-    that should be used for the value of the expression. Below we set it such
-    that an integer value will be treated as an ``Integer``, and any other
-    value is assumed to be a date and will be treated as a ``MyEpochType``::
-
-        def coerce_compared_value(self, op, value):
-            if isinstance(value, int):
-                return Integer()

-"""Visitor/traversal interface and library functions.
-
-SQLAlchemy schema and expression constructs rely on a Python-centric
-version of the classic "visitor" pattern as the primary way in which
-they apply functionality.  The most common use of this pattern
-is statement compilation, where individual expression classes match
-up to rendering methods that produce a string result.   Beyond this,
-the visitor system is also used to inspect expressions for various
-information and patterns, as well as for usage in
-some kinds of expression transformation.  Other kinds of transformation
-use a non-visitor traversal system.
-
-For many examples of how the visit system is used, see the
-sqlalchemy.sql.util and the sqlalchemy.sql.compiler modules.
-For an introduction to clause adaption, see

-Nose test runner module.
-
-This script is a front-end to "nosetests" which
-installs SQLAlchemy's testing plugin into the local environment.
-
-The script is intended to be used by third-party dialects and extensions
-that run within SQLAlchemy's testing framework.    The runner can
-be invoked via::
-
-    python -m sqlalchemy.testing.runner
-
-The script is then essentially the same as the "nosetests" script, including
-all of the usual Nose options.   The test environment requires that a
-setup.cfg is locally present including various required options.
-
-Note that when using this runner, Nose's "coverage" plugin will not be
-able to provide coverage for SQLAlchemy itself, since SQLAlchemy is
-imported into sys.modules before coverage is started.   The special
-script sqla_nose.py is provided as a top-level script which loads the
-plugin in a special (somewhat hacky) way so that coverage against
-SQLAlchemy itself is possible.

+Description: SQLAlchemy
+        ==========
+        
+        The Python SQL Toolkit and Object Relational Mapper
+        
+        Introduction
+        -------------
+        
+        SQLAlchemy is the Python SQL toolkit and Object Relational Mapper
+        that gives application developers the full power and
+        flexibility of SQL. SQLAlchemy provides a full suite
+        of well known enterprise-level persistence patterns,
+        designed for efficient and high-performing database
+        access, adapted into a simple and Pythonic domain
+        language.
+        
+        Major SQLAlchemy features include:
+        
+        * An industrial strength ORM, built 
+          from the core on the identity map, unit of work,
+          and data mapper patterns.   These patterns
+          allow transparent persistence of objects 
+          using a declarative configuration system.
+          Domain models
+          can be constructed and manipulated naturally,
+          and changes are synchronized with the
+          current transaction automatically.
+        * A relationally-oriented query system, exposing
+          the full range of SQL's capabilities 
+          explicitly, including joins, subqueries, 
+          correlation, and most everything else, 
+          in terms of the object model.
+          Writing queries with the ORM uses the same 
+          techniques of relational composition you use 
+          when writing SQL.  While you can drop into
+          literal SQL at any time, it's virtually never
+          needed.
+        * A comprehensive and flexible system 
+          of eager loading for related collections and objects.
+          Collections are cached within a session,
+          and can be loaded on individual access, all 
+          at once using joins, or by query per collection
+          across the full result set.
+        * A Core SQL construction system and DBAPI 
+          interaction layer.  The SQLAlchemy Core is
+          separate from the ORM and is a full database
+          abstraction layer in its own right, and includes
+          an extensible Python-based SQL expression 
+          language, schema metadata, connection pooling, 
+          type coercion, and custom types.
+        * All primary and foreign key constraints are 
+          assumed to be composite and natural.  Surrogate
+          integer primary keys are of course still the 
+          norm, but SQLAlchemy never assumes or hardcodes
+          to this model.
+        * Database introspection and generation.  Database
+          schemas can be "reflected" in one step into
+          Python structures representing database metadata;
+          those same structures can then generate 
+          CREATE statements right back out - all within
+          the Core, independent of the ORM.
+        
+        SQLAlchemy's philosophy:
+        
+        * SQL databases behave less and less like object
+          collections the more size and performance start to
+          matter; object collections behave less and less like
+          tables and rows the more abstraction starts to matter.
+          SQLAlchemy aims to accommodate both of these
+          principles.
+        * An ORM doesn't need to hide the "R".   A relational
+          database provides rich, set-based functionality
+          that should be fully exposed.   SQLAlchemy's
+          ORM provides an open-ended set of patterns
+          that allow a developer to construct a custom
+          mediation layer between a domain model and 
+          a relational schema, turning the so-called
+          "object relational impedance" issue into
+          a distant memory.
+        * The developer, in all cases, makes all decisions
+          regarding the design, structure, and naming conventions
+          of both the object model as well as the relational
+          schema.   SQLAlchemy only provides the means
+          to automate the execution of these decisions.
+        * With SQLAlchemy, there's no such thing as 
+          "the ORM generated a bad query" - you 
+          retain full control over the structure of 
+          queries, including how joins are organized,
+          how subqueries and correlation is used, what 
+          columns are requested.  Everything SQLAlchemy
+          does is ultimately the result of a developer-
+          initiated decision.
+        * Don't use an ORM if the problem doesn't need one.
+          SQLAlchemy consists of a Core and separate ORM
+          component.   The Core offers a full SQL expression
+          language that allows Pythonic construction 
+          of SQL constructs that render directly to SQL
+          strings for a target database, returning
+          result sets that are essentially enhanced DBAPI
+          cursors.
+        * Transactions should be the norm.  With SQLAlchemy's
+          ORM, nothing goes to permanent storage until
+          commit() is called.  SQLAlchemy encourages applications
+          to create a consistent means of delineating
+          the start and end of a series of operations.
+        * Never render a literal value in a SQL statement.
+          Bound parameters are used to the greatest degree
+          possible, allowing query optimizers to cache 
+          query plans effectively and making SQL injection
+          attacks a non-issue.

+        
+        ``cryptography`` is a package which provides cryptographic recipes and
+        primitives to Python developers.  Our goal is for it to be your "cryptographic
+        standard library". It supports Python 2.6-2.7, Python 3.2+, and PyPy.
+        
+        ``cryptography`` includes both high level recipes, and low level interfaces to
+        common cryptographic algorithms such as symmetric ciphers, message digests and
+        key derivation functions. For example, to encrypt something with
+        ``cryptography``'s high level symmetric encryption recipe:
+        
+        .. code-block:: pycon
+        
+            >>> from cryptography.fernet import Fernet
+            >>> # Put this somewhere safe!
+            >>> key = Fernet.generate_key()
+            >>> f = Fernet(key)
+            >>> token = f.encrypt(b"A really secret message. Not for prying eyes.")
+            >>> token
+            '...'
+            >>> f.decrypt(token)
+            'A really secret message. Not for prying eyes.'
+        
+        You can find more information in the `documentation`_.
+        
+        Discussion
+        ~~~~~~~~~~
+        
+        If you run into bugs, you can file them in our `issue tracker`_.
+        
+        We maintain a `cryptography-dev`_ mailing list for development discussion.
+        
+        You can also join ``#cryptography-dev`` on Freenode to ask questions or get
+        involved.

+Metadata-Version: 1.1
+Name: ed25519
+Version: 1.3
+Summary: Ed25519 public-key signatures
+Home-page: https://github.com/warner/python-ed25519
+Author: Brian Warner
+Author-email: warner-python-ed25519@lothar.com
+License: MIT
+Description: Python bindings to the Ed25519 public-key signature system.
+        
+        This offers a comfortable python interface to a C implementation of the
+        Ed25519 public-key signature system (http://ed25519.cr.yp.to/), using the
+        portable 'ref' code from the 'SUPERCOP' benchmarking suite.
+        
+        This system provides high (128-bit) security, short (32-byte) keys, short
+        (64-byte) signatures, and fast (2-6ms) operation. Please see the README for
+        more details.

+Package resource API
+--------------------
+
+A resource is a logical file contained within a package, or a logical
+subdirectory thereof.  The package resource API expects resource names
+to have their path parts separated with ``/``, *not* whatever the local
+path separator is.  Do not use os.path operations to manipulate resource
+names being passed into the API.
+
+The package resource API is designed to work with normal filesystem packages,
+.egg files, and unpacked .egg files.  It can also work in a limited way with
+.zip files and with custom PEP 302 loaders that support the ``get_data()``
+method.

+
+    This is a rough cross between distutils' StrictVersion and LooseVersion;
+    if you give it versions that would work with StrictVersion, then it behaves
+    the same; otherwise it acts like a slightly-smarter LooseVersion. It is
+    *possible* to create pathological version coding schemes that will fool
+    this parser, but they should be very rare in practice.
+
+    The returned value will be a tuple of strings.  Numeric portions of the
+    version are padded to 8 digits so they will compare numerically, but
+    without relying on how numbers compare relative to strings.  Dots are
+    dropped, but dashes are retained.  Trailing zeros between alpha segments
+    or dashes are suppressed, so that e.g. "2.4.0" is considered the same as
+    "2.4". Alphanumeric parts are lower-cased.
+
+    The algorithm assumes that strings like "-" and any alpha string that
+    alphabetically follows "final"  represents a "patch level".  So, "2.4-1"
+    is assumed to be a branch or patch of "2.4", and therefore "2.4.1" is
+    considered newer than "2.4-1", which in turn is newer than "2.4".
+
+    Strings like "a", "b", "c", "alpha", "beta", "candidate" and so on (that
+    come before "final" alphabetically) are assumed to be pre-release versions,
+    so that the version "2.4" is considered newer than "2.4a1".
+
+    Finally, to handle miscellaneous cases, the strings "pre", "preview", and
+    "rc" are treated as if they were "c", i.e. as though they were release
+    candidates, and therefore are not as new as a version string that does not
+    contain them, and "dev" is replaced with an '@' so that it sorts lower than
+    than any other pre-release tag.

+===============================
+Installing and Using Setuptools
+===============================
+
+.. contents:: **Table of Contents**
+
+
+-------------------------
+Installation Instructions
+-------------------------
+
+The recommended way to bootstrap setuptools on any system is to download
+`ez_setup.py`_ and run it using the target Python environment. Different
+operating systems have different recommended techniques to accomplish this
+basic routine, so below are some examples to get you started.
+
+Setuptools requires Python 2.6 or later. To install setuptools
+on Python 2.4 or Python 2.5, use the `bootstrap script for Setuptools 1.x
+<https://bitbucket.org/pypa/setuptools/raw/bootstrap-py24/ez_setup.py>`_.
+
+The link provided to ez_setup.py is a bookmark to bootstrap script for the
+latest known stable release.
+
+.. _ez_setup.py: https://bootstrap.pypa.io/ez_setup.py
+
+Windows (Powershell 3 or later)
+===============================
+
+For best results, uninstall previous versions FIRST (see `Uninstalling`_).
+
+Using Windows 8 (which includes PowerShell 3) or earlier versions of Windows
+with PowerShell 3 installed, it's possible to install with one simple
+Powershell command. Start up Powershell and paste this command::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python -
+
+You must start the Powershell with Administrative privileges or you may choose
+to install a user-local installation::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python - --user
+
+If you have Python 3.3 or later, you can use the ``py`` command to install to
+different Python versions. For example, to install to Python 3.3 if you have
+Python 2.7 installed::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | py -3 -
+
+The recommended way to install setuptools on Windows is to download
+`ez_setup.py`_ and run it. The script will download the appropriate
+distribution file and install it for you.
+
+Once installation is complete, you will find an ``easy_install`` program in
+your Python ``Scripts`` subdirectory.  For simple invocation and best results,
+add this directory to your ``PATH`` environment variable, if it is not already
+present. If you did a user-local install, the ``Scripts`` subdirectory is
+``$env:APPDATA\Python\Scripts``.
+
+
+Windows (simplified)
+====================
+
+For Windows without PowerShell 3 or for installation without a command-line,
+download `ez_setup.py`_ using your preferred web browser or other technique
+and "run" that file.
+
+
+Unix (wget)
+===========
+
+Most Linux distributions come with wget.
+
+Download `ez_setup.py`_ and run it using the target Python version. The script
+will download the appropriate version and install it for you::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | python
+
+Note that you will may need to invoke the command with superuser privileges to
+install to the system Python::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
+
+Alternatively, Setuptools may be installed to a user-local path::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | python - --user
+
+Unix including Mac OS X (curl)
+==============================
+
+If your system has curl installed, follow the ``wget`` instructions but
+replace ``wget`` with ``curl`` and ``-O`` with ``-o``. For example::
+
+    > curl https://bootstrap.pypa.io/ez_setup.py -o - | python
+
+
+Advanced Installation
+=====================
+
+For more advanced installation options, such as installing to custom
+locations or prefixes, download and extract the source
+tarball from `Setuptools on PyPI <https://pypi.python.org/pypi/setuptools>`_
+and run setup.py with any supported distutils and Setuptools options.
+For example::
+
+    setuptools-x.x$ python setup.py install --prefix=/opt/setuptools
+
+Use ``--help`` to get a full options list, but we recommend consulting
+the `EasyInstall manual`_ for detailed instructions, especially `the section
+on custom installation locations`_.
+
+.. _EasyInstall manual: https://pythonhosted.org/setuptools/EasyInstall
+.. _the section on custom installation locations: https://pythonhosted.org/setuptools/EasyInstall#custom-installation-locations
+
+
+Downloads
+=========
+
+All setuptools downloads can be found at `the project's home page in the Python
+Package Index`_.  Scroll to the very bottom of the page to find the links.
+
+.. _the project's home page in the Python Package Index: https://pypi.python.org/pypi/setuptools
+
+In addition to the PyPI downloads, the development version of ``setuptools``
+is available from the `Bitbucket repo`_, and in-development versions of the
+`0.6 branch`_ are available as well.
+
+.. _Bitbucket repo: https://bitbucket.org/pypa/setuptools/get/default.tar.gz#egg=setuptools-dev
+.. _0.6 branch: http://svn.python.org/projects/sandbox/branches/setuptools-0.6/#egg=setuptools-dev06
+
+Uninstalling
+============
+
+On Windows, if Setuptools was installed using an ``.exe`` or ``.msi``
+installer, simply use the uninstall feature of "Add/Remove Programs" in the
+Control Panel.
+
+Otherwise, to uninstall Setuptools or Distribute, regardless of the Python
+version, delete all ``setuptools*`` and ``distribute*`` files and
+directories from your system's ``site-packages`` directory
+(and any other ``sys.path`` directories) FIRST.
+
+If you are upgrading or otherwise plan to re-install Setuptools or Distribute,
+nothing further needs to be done. If you want to completely remove Setuptools,
+you may also want to remove the 'easy_install' and 'easy_install-x.x' scripts
+and associated executables installed to the Python scripts directory.
+
+--------------------------------
+Using Setuptools and EasyInstall
+--------------------------------
+
+Here are some of the available manuals, tutorials, and other resources for
+learning about Setuptools, Python Eggs, and EasyInstall:
+
+* `The EasyInstall user's guide and reference manual`_
+* `The setuptools Developer's Guide`_
+* `The pkg_resources API reference`_
+* `Package Compatibility Notes`_ (user-maintained)
+* `The Internal Structure of Python Eggs`_
+
+Questions, comments, and bug reports should be directed to the `distutils-sig
+mailing list`_.  If you have written (or know of) any tutorials, documentation,
+plug-ins, or other resources for setuptools users, please let us know about
+them there, so this reference list can be updated.  If you have working,
+*tested* patches to correct problems or add features, you may submit them to
+the `setuptools bug tracker`_.

+
+* The original design for the ``.egg`` format and the ``pkg_resources`` API was
+  co-created by Phillip Eby and Bob Ippolito.  Bob also implemented the first
+  version of ``pkg_resources``, and supplied the OS X operating system version
+  compatibility algorithm.
+
+* Ian Bicking implemented many early "creature comfort" features of
+  easy_install, including support for downloading via Sourceforge and
+  Subversion repositories.  Ian's comments on the Web-SIG about WSGI
+  application deployment also inspired the concept of "entry points" in eggs,
+  and he has given talks at PyCon and elsewhere to inform and educate the
+  community about eggs and setuptools.
+
+* Jim Fulton contributed time and effort to build automated tests of various
+  aspects of ``easy_install``, and supplied the doctests for the command-line
+  ``.exe`` wrappers on Windows.
+
+* Phillip J. Eby is the seminal author of setuptools, and
+  first proposed the idea of an importable binary distribution format for
+  Python application plug-ins.
+
+* Significant parts of the implementation of setuptools were funded by the Open
+  Source Applications Foundation, to provide a plug-in infrastructure for the
+  Chandler PIM application.  In addition, many OSAF staffers (such as Mike
+  "Code Bear" Taylor) contributed their time and stress as guinea pigs for the
+  use of eggs and setuptools, even before eggs were "cool".  (Thanks, guys!)
+
+* Tarek Ziadé is the principal author of the Distribute fork, which
+  re-invigorated the community on the project, encouraged renewed innovation,
+  and addressed many defects.
+
+* Since the merge with Distribute, Jason R. Coombs is the
+  maintainer of setuptools.  The project is maintained in coordination with
+  the Python Packaging Authority (PyPA) and the larger Python community.

+
+=======
+CHANGES
+=======
+
+-----
+6.0.2
+-----
+
+* `Issue #262 <https://bitbucket.org/pypa/setuptools/issue/262>`_: Fixed regression in pip install due to egg-info directories
+  being omitted. Re-opens `Issue #118 <https://bitbucket.org/pypa/setuptools/issue/118>`_.
+
+-----
+6.0.1
+-----
+
+* `Issue #259 <https://bitbucket.org/pypa/setuptools/issue/259>`_: Fixed regression with namespace package handling on ``single
+  version, externally managed`` installs.
+
+---
+6.0
+---
+
+* `Issue #100 <https://bitbucket.org/pypa/setuptools/issue/100>`_: When building a distribution, Setuptools will no longer match
+  default files using platform-dependent case sensitivity, but rather will
+  only match the files if their case matches exactly. As a result, on Windows
+  and other case-insensitive file systems, files with names such as
+  'readme.txt' or 'README.TXT' will be omitted from the distribution and a
+  warning will be issued indicating that 'README.txt' was not found. Other
+  filenames affected are:
+
+    - README.rst
+    - README
+    - setup.cfg
+    - setup.py (or the script name)
+    - test/test*.py
+
+  Any users producing distributions with filenames that match those above
+  case-insensitively, but not case-sensitively, should rename those files in
+  their repository for better portability.
+* `Pull Request #72 <https://bitbucket.org/pypa/setuptools/pull-request/72>`_: When using ``single_version_externally_managed``, the
+  exclusion list now includes Python 3.2 ``__pycache__`` entries.
+* `Pull Request #76 <https://bitbucket.org/pypa/setuptools/pull-request/76>`_ and `Pull Request #78 <https://bitbucket.org/pypa/setuptools/pull-request/78>`_: lines in top_level.txt are now
+  ordered deterministically.
+* `Issue #118 <https://bitbucket.org/pypa/setuptools/issue/118>`_: The egg-info directory is now no longer included in the list
+  of outputs.
+* `Issue #258 <https://bitbucket.org/pypa/setuptools/issue/258>`_: Setuptools now patches distutils msvc9compiler to
+  recognize the specially-packaged compiler package for easy extension module
+  support on Python 2.6, 2.7, and 3.2.
+
+---
+5.8
+---
+
+* `Issue #237 <https://bitbucket.org/pypa/setuptools/issue/237>`_: ``pkg_resources`` now uses explicit detection of Python 2 vs.
+  Python 3, supporting environments where builtins have been patched to make
+  Python 3 look more like Python 2.
+
+---
+5.7
+---
+
+* `Issue #240 <https://bitbucket.org/pypa/setuptools/issue/240>`_: Based on real-world performance measures against 5.4, zip
+  manifests are now cached in all circumstances. The
+  ``PKG_RESOURCES_CACHE_ZIP_MANIFESTS`` environment variable is no longer
+  relevant. The observed "memory increase" referenced in the 5.4 release
+  notes and detailed in `Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154>`_ was likely not an increase over the status
+  quo, but rather only an increase over not storing the zip info at all.
+
+---
+5.6
+---
+
+* `Issue #242 <https://bitbucket.org/pypa/setuptools/issue/242>`_: Use absolute imports in svn_utils to avoid issues if the
+  installing package adds an xml module to the path.
+
+-----
+5.5.1
+-----
+
+* `Issue #239 <https://bitbucket.org/pypa/setuptools/issue/239>`_: Fix typo in 5.5 such that fix did not take.
+
+---
+5.5
+---
+
+* `Issue #239 <https://bitbucket.org/pypa/setuptools/issue/239>`_: Setuptools now includes the setup_requires directive on
+  Distribution objects and validates the syntax just like install_requires
+  and tests_require directives.
+
+-----
+5.4.2
+-----
+
+* `Issue #236 <https://bitbucket.org/pypa/setuptools/issue/236>`_: Corrected regression in execfile implementation for Python 2.6.
+
+-----
+5.4.1
+-----
+
+* `Python #7776 <http://bugs.python.org/issue7776>`_: (ssl_support) Correct usage of host for validation when
+  tunneling for HTTPS.
+
+---
+5.4
+---
+
+* `Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154>`_: ``pkg_resources`` will now cache the zip manifests rather than
+  re-processing the same file from disk multiple times, but only if the
+  environment variable ``PKG_RESOURCES_CACHE_ZIP_MANIFESTS`` is set. Clients
+  that package many modules in the same zip file will see some improvement
+  in startup time by enabling this feature. This feature is not enabled by
+  default because it causes a substantial increase in memory usage.
+
+---
+5.3
+---
+
+* `Issue #185 <https://bitbucket.org/pypa/setuptools/issue/185>`_: Make svn tagging work on the new style SVN metadata.
+  Thanks cazabon!
+* Prune revision control directories (e.g .svn) from base path
+  as well as sub-directories.
+
+---
+5.2
+---
+
+* Added a `Developer Guide
+  <https://pythonhosted.org/setuptools/developer-guide.html>`_ to the official
+  documentation.
+* Some code refactoring and cleanup was done with no intended behavioral
+  changes.
+* During install_egg_info, the generated lines for namespace package .pth
+  files are now processed even during a dry run.
+
+---
+5.1
+---
+
+* `Issue #202 <https://bitbucket.org/pypa/setuptools/issue/202>`_: Implemented more robust cache invalidation for the ZipImporter,
+  building on the work in `Issue #168 <https://bitbucket.org/pypa/setuptools/issue/168>`_. Special thanks to Jurko Gospodnetic and
+  PJE.
+
+-----
+5.0.2
+-----
+
+* `Issue #220 <https://bitbucket.org/pypa/setuptools/issue/220>`_: Restored script templates.
+
+-----
+5.0.1
+-----
+
+* Renamed script templates to end with .tmpl now that they no longer need
+  to be processed by 2to3. Fixes spurious syntax errors during build/install.
+
+---
+5.0
+---
+
+* `Issue #218 <https://bitbucket.org/pypa/setuptools/issue/218>`_: Re-release of 3.8.1 to signal that it supersedes 4.x.
+* Incidentally, script templates were updated not to include the triple-quote
+  escaping.
+
+-------------------------
+3.7.1 and 3.8.1 and 4.0.1
+-------------------------
+
+* `Issue #213 <https://bitbucket.org/pypa/setuptools/issue/213>`_: Use legacy StringIO behavior for compatibility under pbr.
+* `Issue #218 <https://bitbucket.org/pypa/setuptools/issue/218>`_: Setuptools 3.8.1 superseded 4.0.1, and 4.x was removed
+  from the available versions to install.
+
+---
+4.0
+---
+
+* `Issue #210 <https://bitbucket.org/pypa/setuptools/issue/210>`_: ``setup.py develop`` now copies scripts in binary mode rather
+  than text mode, matching the behavior of the ``install`` command.
+
+---
+3.8
+---
+
+* Extend `Issue #197 <https://bitbucket.org/pypa/setuptools/issue/197>`_ workaround to include all Python 3 versions prior to
+  3.2.2.
+
+---
+3.7

+* `Issue #12 <https://bitbucket.org/pypa/setuptools/issue/12>`_: Namespace packages are now imported lazily.  That is, the mere
+  declaration of a namespace package in an egg on ``sys.path`` no longer
+  causes it to be imported when ``pkg_resources`` is imported.  Note that this
+  change means that all of a namespace package's ``__init__.py`` files must
+  include a ``declare_namespace()`` call in order to ensure that they will be
+  handled properly at runtime.  In 2.x it was possible to get away without
+  including the declaration, but only at the cost of forcing namespace
+  packages to be imported early, which 3.0 no longer does.
+* `Issue #148 <https://bitbucket.org/pypa/setuptools/issue/148>`_: When building (bdist_egg), setuptools no longer adds
+  ``__init__.py`` files to namespace packages. Any packages that rely on this
+  behavior will need to create ``__init__.py`` files and include the
+  ``declare_namespace()``.
+* `Issue #7 <https://bitbucket.org/pypa/setuptools/issue/7>`_: Setuptools itself is now distributed as a zip archive in addition to

+
+* `Issue #105 <https://bitbucket.org/pypa/setuptools/issue/105>`_ and `Issue #113 <https://bitbucket.org/pypa/setuptools/issue/113>`_: Establish a more robust technique for
+  determining the terminal encoding::
+
+    1. Try ``getpreferredencoding``
+    2. If that returns US_ASCII or None, try the encoding from
+       ``getdefaultlocale``. If that encoding was a "fallback" because Python
+       could not figure it out from the environment or OS, encoding remains
+       unresolved.
+    3. If the encoding is resolved, then make sure Python actually implements
+       the encoding.
+    4. On the event of an error or unknown codec, revert to fallbacks
+       (UTF-8 on Darwin, ASCII on everything else).
+    5. On the encoding is 'mac-roman' on Darwin, use UTF-8 as 'mac-roman' was
+       a bug on older Python releases.
+
+    On a side note, it would seem that the encoding only matters for when SVN
+    does not yet support ``--xml`` and when getting repository and svn version
+    numbers. The ``--xml`` technique should yield UTF-8 according to some
+    messages on the SVN mailing lists. So if the version numbers are always
+    7-bit ASCII clean, it may be best to only support the file parsing methods
+    for legacy SVN releases and support for SVN without the subprocess command
+    would simple go away as support for the older SVNs does.

+  reported in `Issue #108 <https://bitbucket.org/pypa/setuptools/issue/108>`_, as of Pip 1.4, scripts aren't installed properly
+  from wheels. Therefore, if using Pip to install setuptools from a wheel,
+  the ``easy_install`` command will not be available.
+* Setuptools "natural" launcher support, introduced in 1.0, is now officially
+  supported.
+
+-----
+1.1.7
+-----
+
+* Fixed behavior of NameError handling in 'script template (dev).py' (script

+
+---
+1.0
+---
+
+* `Issue #60 <https://bitbucket.org/pypa/setuptools/issue/60>`_: On Windows, Setuptools supports deferring to another launcher,
+  such as Vinay Sajip's `pylauncher <https://bitbucket.org/pypa/pylauncher>`_
+  (included with Python 3.3) to launch console and GUI scripts and not install
+  its own launcher executables. This experimental functionality is currently
+  only enabled if  the ``SETUPTOOLS_LAUNCHER`` environment variable is set to
+  "natural". In the future, this behavior may become default, but only after
+  it has matured and seen substantial adoption. The ``SETUPTOOLS_LAUNCHER``
+  also accepts "executable" to force the default behavior of creating launcher
+  executables.
+* `Issue #63 <https://bitbucket.org/pypa/setuptools/issue/63>`_: Bootstrap script (ez_setup.py) now prefers Powershell, curl, or
+  wget for retrieving the Setuptools tarball for improved security of the
+  install. The script will still fall back to a simple ``urlopen`` on
+  platforms that do not have these tools.
+* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Deprecated the ``Features`` functionality.
+* `Issue #52 <https://bitbucket.org/pypa/setuptools/issue/52>`_: In ``VerifyingHTTPSConn``, handle a tunnelled (proxied)
+  connection.
+
+Backward-Incompatible Changes
+=============================
+
+This release includes a couple of backward-incompatible changes, but most if
+not all users will find 1.0 a drop-in replacement for 0.9.
+
+* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: Normalized API of environment marker support. Specifically,
+  removed line number and filename from SyntaxErrors when returned from
+  `pkg_resources.invalid_marker`. Any clients depending on the specific
+  string representation of exceptions returned by that function may need to
+  be updated to account for this change.
+* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: SyntaxErrors generated by `pkg_resources.invalid_marker` are
+  normalized for cross-implementation consistency.
+* Removed ``--ignore-conflicts-at-my-risk`` and ``--delete-conflicting``
+  options to easy_install. These options have been deprecated since 0.6a11.
+
+-----
+0.9.8

+  referenced by bookmark.

+-----
+
+* `Issue #44 <https://bitbucket.org/pypa/setuptools/issue/44>`_: Test failure on Python 2.4 when MD5 hash doesn't have a `.name`

+-----
+
+* `Distribute #386 <https://bitbucket.org/tarek/distribute/issue/386>`_: Allow other positional and keyword arguments to os.open.

+  conversion.
+
+-----
+0.7.8

+
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Repair AttributeError created in last release (redo).

+* Now honor the environment variable
+  ``SETUPTOOLS_DISABLE_VERSIONED_EASY_INSTALL_SCRIPT`` in addition to the now
+  deprecated ``DISTRIBUTE_DISABLE_VERSIONED_EASY_INSTALL_SCRIPT``.
+
+-----
+0.7.4
+-----
+
+* `Issue #20 <https://bitbucket.org/pypa/setuptools/issue/20>`_: Fix comparison of parsed SVN version on Python 3.
+
+-----
+0.7.3
+-----
+
+* `Issue #1 <https://bitbucket.org/pypa/setuptools/issue/1>`_: Disable installation of Windows-specific files on non-Windows systems.
+* Use new sysconfig module with Python 2.7 or >=3.2.
+
+-----
+0.7.2

+
+* `Issue #14 <https://bitbucket.org/pypa/setuptools/issue/14>`_: Use markerlib when the `parser` module is not available.
+* `Issue #10 <https://bitbucket.org/pypa/setuptools/issue/10>`_: ``ez_setup.py`` now uses HTTPS to download setuptools from PyPI.
+
+-----
+0.7.1
+-----
+
+* Fix NameError (`Issue #3 <https://bitbucket.org/pypa/setuptools/issue/3>`_) again - broken in bad merge.
+
+---
+0.7
+---
+
+* Merged Setuptools and Distribute. See docs/merge.txt for details.
+
+Added several features that were slated for setuptools 0.6c12:
+
+* Index URL now defaults to HTTPS.
+* Added experimental environment marker support. Now clients may designate a
+  PEP-426 environment marker for "extra" dependencies. Setuptools uses this
+  feature in ``setup.py`` for optional SSL and certificate validation support
+  on older platforms. Based on Distutils-SIG discussions, the syntax is
+  somewhat tentative. There should probably be a PEP with a firmer spec before
+  the feature should be considered suitable for use.
+* Added support for SSL certificate validation when installing packages from
+  an HTTPS service.
+
+-----
+0.7b4
+-----
+
+* `Issue #3 <https://bitbucket.org/pypa/setuptools/issue/3>`_: Fixed NameError in SSL support.
+
+------
+0.6.49
+------
+
+* Move warning check in ``get_cache_path`` to follow the directory creation
+  to avoid errors when the cache path does not yet exist. Fixes the error
+  reported in `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_.
+
+------
+0.6.48
+------
+
+* Correct AttributeError in ``ResourceManager.get_cache_path`` introduced in
+  0.6.46 (redo).
+
+------
+0.6.47
+------
+
+* Correct AttributeError in ``ResourceManager.get_cache_path`` introduced in

+
+------
+0.6.46
+------
+
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Issue a warning if the PYTHON_EGG_CACHE or otherwise
+  customized egg cache location specifies a directory that's group- or
+  world-writable.
+
+------
+0.6.45
+------
+
+* `Distribute #379 <https://bitbucket.org/tarek/distribute/issue/379>`_: ``distribute_setup.py`` now traps VersionConflict as well,
+  restoring ability to upgrade from an older setuptools version.
+
+------
+0.6.44
+------
+
+* ``distribute_setup.py`` has been updated to allow Setuptools 0.7 to
+  satisfy use_setuptools.
+
+------
+0.6.43
+------
+
+* `Distribute #378 <https://bitbucket.org/tarek/distribute/issue/378>`_: Restore support for Python 2.4 Syntax (regression in 0.6.42).
+
+------
+0.6.42
+------
+
+* External links finder no longer yields duplicate links.
+* `Distribute #337 <https://bitbucket.org/tarek/distribute/issue/337>`_: Moved site.py to setuptools/site-patch.py (graft of very old
+  patch from setuptools trunk which inspired PR `#31 <https://bitbucket.org/pypa/setuptools/issue/31>`_).
+
+------
+0.6.41
+------
+
+* `Distribute #27 <https://bitbucket.org/tarek/distribute/issue/27>`_: Use public api for loading resources from zip files rather than
+  the private method `_zip_directory_cache`.
+* Added a new function ``easy_install.get_win_launcher`` which may be used by
+  third-party libraries such as buildout to get a suitable script launcher.
+
+------
+0.6.40
+------
+
+* `Distribute #376 <https://bitbucket.org/tarek/distribute/issue/376>`_: brought back cli.exe and gui.exe that were deleted in the
+  previous release.
+
+------
+0.6.39
+------
+
+* Add support for console launchers on ARM platforms.
+* Fix possible issue in GUI launchers where the subsystem was not supplied to
+  the linker.
+* Launcher build script now refactored for robustness.
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Resources extracted from a zip egg to the file system now also
+  check the contents of the file against the zip contents during each
+  invocation of get_resource_filename.
+
+------
+0.6.38
+------
+
+* `Distribute #371 <https://bitbucket.org/tarek/distribute/issue/371>`_: The launcher manifest file is now installed properly.
+
+------
+0.6.37
+------
+
+* `Distribute #143 <https://bitbucket.org/tarek/distribute/issue/143>`_: Launcher scripts, including easy_install itself, are now
+  accompanied by a manifest on 32-bit Windows environments to avoid the
+  Installer Detection Technology and thus undesirable UAC elevation described
+  in `this Microsoft article
+  <http://technet.microsoft.com/en-us/library/cc709628%28WS.10%29.aspx>`_.

+
+* `Pull Request #35 <https://bitbucket.org/pypa/setuptools/pull-request/35>`_: In `Buildout #64 <https://github.com/buildout/buildout/issues/64>`_, it was reported that
+  under Python 3, installation of distutils scripts could attempt to copy
+  the ``__pycache__`` directory as a file, causing an error, apparently only
+  under Windows. Easy_install now skips all directories when processing
+  metadata scripts.
+
+------

+* `Distribute #334 <https://bitbucket.org/tarek/distribute/issue/334>`_: Provide workaround for packages that reference `sys.__stdout__`
+  such as numpy does. This change should address
+  `virtualenv `#359 <https://bitbucket.org/pypa/setuptools/issue/359>`_ <https://github.com/pypa/virtualenv/issues/359>`_ as long
+  as the system encoding is UTF-8 or the IO encoding is specified in the
+  environment, i.e.::
+
+     PYTHONIOENCODING=utf8 pip install numpy
+
+* Fix for encoding issue when installing from Windows executable on Python 3.
+* `Distribute #323 <https://bitbucket.org/tarek/distribute/issue/323>`_: Allow `setup_requires` requirements to supercede installed
+  requirements. Added some new keyword arguments to existing pkg_resources
+  methods. Also had to updated how __path__ is handled for namespace packages
+  to ensure that when a new egg distribution containing a namespace package is
+  placed on sys.path, the entries in __path__ are found in the same order they
+  would have been in had that egg been on the path when pkg_resources was
+  first imported.

+  as the egg link would go to the Python 2 source. Linking to the 2to3'd code
+  in build/lib makes it work, although you will have to rebuild the module
+  before testing it.
+* `Distribute #306 <https://bitbucket.org/tarek/distribute/issue/306>`_: Even if 2to3 is used, we build in-place under Python 2.

+
+* Added compatibility with Subversion 1.6. This references `Distribute #1 <https://bitbucket.org/tarek/distribute/issue/1>`_.
+
+pkg_resources
+=============
+
+* Avoid a call to /usr/bin/sw_vers on OSX and use the official platform API
+  instead. Based on a patch from ronaldoussoren. This closes issue `#5 <https://bitbucket.org/pypa/setuptools/issue/5>`_.

+
+-----
+0.6c9
+-----
+
+ * Fixed a missing files problem when using Windows source distributions on
+   non-Windows platforms, due to distutils not handling manifest file line
+   endings correctly.
+
+ * Updated Pyrex support to work with Pyrex 0.9.6 and higher.
+
+ * Minor changes for Jython compatibility, including skipping tests that can't
+   work on Jython.
+
+ * Fixed not installing eggs in ``install_requires`` if they were also used for
+   ``setup_requires`` or ``tests_require``.
+
+ * Fixed not fetching eggs in ``install_requires`` when running tests.
+
+ * Allow ``ez_setup.use_setuptools()`` to upgrade existing setuptools
+   installations when called from a standalone ``setup.py``.
+
+ * Added a warning if a namespace package is declared, but its parent package
+   is not also declared as a namespace.
+
+ * Support Subversion 1.5
+
+ * Removed use of deprecated ``md5`` module if ``hashlib`` is available
+
+ * Fixed ``bdist_wininst upload`` trying to upload the ``.exe`` twice
+
+ * Fixed ``bdist_egg`` putting a ``native_libs.txt`` in the source package's
+   ``.egg-info``, when it should only be in the built egg's ``EGG-INFO``.
+
+ * Ensure that _full_name is set on all shared libs before extensions are
+   checked for shared lib usage.  (Fixes a bug in the experimental shared
+   library build support.)
+
+ * Fix to allow unpacked eggs containing native libraries to fail more
+   gracefully under Google App Engine (with an ``ImportError`` loading the
+   C-based module, instead of getting a ``NameError``).
+
+-----
+0.6c7
+-----
+
+ * Fixed ``distutils.filelist.findall()`` crashing on broken symlinks, and
+   ``egg_info`` command failing on new, uncommitted SVN directories.
+
+ * Fix import problems with nested namespace packages installed via
+   ``--root`` or ``--single-version-externally-managed``, due to the
+   parent package not having the child package as an attribute.
+
+-----
+0.6c6
+-----
+
+ * Added ``--egg-path`` option to ``develop`` command, allowing you to force
+   ``.egg-link`` files to use relative paths (allowing them to be shared across
+   platforms on a networked drive).
+
+ * Fix not building binary RPMs correctly.
+
+ * Fix "eggsecutables" (such as setuptools' own egg) only being runnable with
+   bash-compatible shells.
+
+ * Fix ``#!`` parsing problems in Windows ``.exe`` script wrappers, when there
+   was whitespace inside a quoted argument or at the end of the ``#!`` line
+   (a regression introduced in 0.6c4).
+
+ * Fix ``test`` command possibly failing if an older version of the project
+   being tested was installed on ``sys.path`` ahead of the test source
+   directory.
+
+ * Fix ``find_packages()`` treating ``ez_setup`` and directories with ``.`` in
+   their names as packages.
+
+-----
+0.6c5
+-----
+
+ * Fix uploaded ``bdist_rpm`` packages being described as ``bdist_egg``
+   packages under Python versions less than 2.5.
+
+ * Fix uploaded ``bdist_wininst`` packages being described as suitable for
+   "any" version by Python 2.5, even if a ``--target-version`` was specified.
+
+-----
+0.6c4
+-----
+
+ * Overhauled Windows script wrapping to support ``bdist_wininst`` better.
+   Scripts installed with ``bdist_wininst`` will always use ``#!python.exe`` or
+   ``#!pythonw.exe`` as the executable name (even when built on non-Windows
+   platforms!), and the wrappers will look for the executable in the script's
+   parent directory (which should find the right version of Python).
+
+ * Fix ``upload`` command not uploading files built by ``bdist_rpm`` or
+   ``bdist_wininst`` under Python 2.3 and 2.4.
+
+ * Add support for "eggsecutable" headers: a ``#!/bin/sh`` script that is
+   prepended to an ``.egg`` file to allow it to be run as a script on Unix-ish
+   platforms.  (This is mainly so that setuptools itself can have a single-file
+   installer on Unix, without doing multiple downloads, dealing with firewalls,
+   etc.)
+
+ * Fix problem with empty revision numbers in Subversion 1.4 ``entries`` files
+
+ * Use cross-platform relative paths in ``easy-install.pth`` when doing
+   ``develop`` and the source directory is a subdirectory of the installation
+   target directory.
+
+ * Fix a problem installing eggs with a system packaging tool if the project
+   contained an implicit namespace package; for example if the ``setup()``
+   listed a namespace package ``foo.bar`` without explicitly listing ``foo``
+   as a namespace package.
+
+-----
+0.6c3
+-----
+
+ * Fixed breakages caused by Subversion 1.4's new "working copy" format
+
+-----
+0.6c2
+-----
+
+ * The ``ez_setup`` module displays the conflicting version of setuptools (and
+   its installation location) when a script requests a version that's not
+   available.
+
+ * Running ``setup.py develop`` on a setuptools-using project will now install
+   setuptools if needed, instead of only downloading the egg.
+
+-----
+0.6c1
+-----
+
+ * Fixed ``AttributeError`` when trying to download a ``setup_requires``
+   dependency when a distribution lacks a ``dependency_links`` setting.
+
+ * Made ``zip-safe`` and ``not-zip-safe`` flag files contain a single byte, so
+   as to play better with packaging tools that complain about zero-length
+   files.
+
+ * Made ``setup.py develop`` respect the ``--no-deps`` option, which it
+   previously was ignoring.
+
+ * Support ``extra_path`` option to ``setup()`` when ``install`` is run in
+   backward-compatibility mode.
+
+ * Source distributions now always include a ``setup.cfg`` file that explicitly
+   sets ``egg_info`` options such that they produce an identical version number
+   to the source distribution's version number.  (Previously, the default
+   version number could be different due to the use of ``--tag-date``, or if
+   the version was overridden on the command line that built the source
+   distribution.)
+
+-----
+0.6b4
+-----
+
+ * Fix ``register`` not obeying name/version set by ``egg_info`` command, if
+   ``egg_info`` wasn't explicitly run first on the same command line.
+
+ * Added ``--no-date`` and ``--no-svn-revision`` options to ``egg_info``
+   command, to allow suppressing tags configured in ``setup.cfg``.
+
+ * Fixed redundant warnings about missing ``README`` file(s); it should now
+   appear only if you are actually a source distribution.
+
+-----
+0.6b3
+-----
+
+ * Fix ``bdist_egg`` not including files in subdirectories of ``.egg-info``.
+
+ * Allow ``.py`` files found by the ``include_package_data`` option to be
+   automatically included.  Remove duplicate data file matches if both
+   ``include_package_data`` and ``package_data`` are used to refer to the same
+   files.
+
+-----
+0.6b1
+-----
+
+ * Strip ``module`` from the end of compiled extension modules when computing
+   the name of a ``.py`` loader/wrapper.  (Python's import machinery ignores
+   this suffix when searching for an extension module.)
+
+------
+0.6a11
+------
+
+ * Added ``test_loader`` keyword to support custom test loaders
+
+ * Added ``setuptools.file_finders`` entry point group to allow implementing
+   revision control plugins.
+
+ * Added ``--identity`` option to ``upload`` command.
+
+ * Added ``dependency_links`` to allow specifying URLs for ``--find-links``.
+
+ * Enhanced test loader to scan packages as well as modules, and call
+   ``additional_tests()`` if present to get non-unittest tests.
+
+ * Support namespace packages in conjunction with system packagers, by omitting
+   the installation of any ``__init__.py`` files for namespace packages, and
+   adding a special ``.pth`` file to create a working package in
+   ``sys.modules``.
+
+ * Made ``--single-version-externally-managed`` automatic when ``--root`` is
+   used, so that most system packagers won't require special support for
+   setuptools.
+
+ * Fixed ``setup_requires``, ``tests_require``, etc. not using ``setup.cfg`` or
+   other configuration files for their option defaults when installing, and
+   also made the install use ``--multi-version`` mode so that the project
+   directory doesn't need to support .pth files.
+
+ * ``MANIFEST.in`` is now forcibly closed when any errors occur while reading
+   it.  Previously, the file could be left open and the actual error would be
+   masked by problems trying to remove the open file on Windows systems.
+
+------
+0.6a10
+------
+
+ * Fixed the ``develop`` command ignoring ``--find-links``.
+
+-----
+0.6a9
+-----
+
+ * The ``sdist`` command no longer uses the traditional ``MANIFEST`` file to
+   create source distributions.  ``MANIFEST.in`` is still read and processed,
+   as are the standard defaults and pruning.  But the manifest is built inside
+   the project's ``.egg-info`` directory as ``SOURCES.txt``, and it is rebuilt
+   every time the ``egg_info`` command is run.
+
+ * Added the ``include_package_data`` keyword to ``setup()``, allowing you to
+   automatically include any package data listed in revision control or
+   ``MANIFEST.in``
+
+ * Added the ``exclude_package_data`` keyword to ``setup()``, allowing you to
+   trim back files included via the ``package_data`` and
+   ``include_package_data`` options.
+
+ * Fixed ``--tag-svn-revision`` not working when run from a source
+   distribution.
+
+ * Added warning for namespace packages with missing ``declare_namespace()``
+
+ * Added ``tests_require`` keyword to ``setup()``, so that e.g. packages
+   requiring ``nose`` to run unit tests can make this dependency optional
+   unless the ``test`` command is run.
+
+ * Made all commands that use ``easy_install`` respect its configuration
+   options, as this was causing some problems with ``setup.py install``.
+
+ * Added an ``unpack_directory()`` driver to ``setuptools.archive_util``, so
+   that you can process a directory tree through a processing filter as if it
+   were a zipfile or tarfile.
+
+ * Added an internal ``install_egg_info`` command to use as part of old-style
+   ``install`` operations, that installs an ``.egg-info`` directory with the
+   package.
+
+ * Added a ``--single-version-externally-managed`` option to the ``install``
+   command so that you can more easily wrap a "flat" egg in a system package.
+
+ * Enhanced ``bdist_rpm`` so that it installs single-version eggs that
+   don't rely on a ``.pth`` file.  The ``--no-egg`` option has been removed,
+   since all RPMs are now built in a more backwards-compatible format.
+
+ * Support full roundtrip translation of eggs to and from ``bdist_wininst``
+   format.  Running ``bdist_wininst`` on a setuptools-based package wraps the
+   egg in an .exe that will safely install it as an egg (i.e., with metadata
+   and entry-point wrapper scripts), and ``easy_install`` can turn the .exe
+   back into an ``.egg`` file or directory and install it as such.
+
+
+-----
+0.6a8
+-----
+
+ * Fixed some problems building extensions when Pyrex was installed, especially
+   with Python 2.4 and/or packages using SWIG.
+
+ * Made ``develop`` command accept all the same options as ``easy_install``,
+   and use the ``easy_install`` command's configuration settings as defaults.
+
+ * Made ``egg_info --tag-svn-revision`` fall back to extracting the revision
+   number from ``PKG-INFO`` in case it is being run on a source distribution of
+   a snapshot taken from a Subversion-based project.
+
+ * Automatically detect ``.dll``, ``.so`` and ``.dylib`` files that are being
+   installed as data, adding them to ``native_libs.txt`` automatically.
+
+ * Fixed some problems with fresh checkouts of projects that don't include
+   ``.egg-info/PKG-INFO`` under revision control and put the project's source
+   code directly in the project directory.  If such a package had any
+   requirements that get processed before the ``egg_info`` command can be run,
+   the setup scripts would fail with a "Missing 'Version:' header and/or
+   PKG-INFO file" error, because the egg runtime interpreted the unbuilt
+   metadata in a directory on ``sys.path`` (i.e. the current directory) as
+   being a corrupted egg.  Setuptools now monkeypatches the distribution
+   metadata cache to pretend that the egg has valid version information, until
+   it has a chance to make it actually be so (via the ``egg_info`` command).
+
+-----
+0.6a5
+-----
+
+ * Fixed missing gui/cli .exe files in distribution.  Fixed bugs in tests.
+
+-----
+0.6a3
+-----
+
+ * Added ``gui_scripts`` entry point group to allow installing GUI scripts
+   on Windows and other platforms.  (The special handling is only for Windows;
+   other platforms are treated the same as for ``console_scripts``.)
+
+-----
+0.6a2
+-----
+
+ * Added ``console_scripts`` entry point group to allow installing scripts
+   without the need to create separate script files.  On Windows, console
+   scripts get an ``.exe`` wrapper so you can just type their name.  On other
+   platforms, the scripts are written without a file extension.
+
+-----
+0.6a1
+-----
+
+ * Added support for building "old-style" RPMs that don't install an egg for
+   the target package, using a ``--no-egg`` option.
+
+ * The ``build_ext`` command now works better when using the ``--inplace``
+   option and multiple Python versions.  It now makes sure that all extensions
+   match the current Python version, even if newer copies were built for a
+   different Python version.
+
+ * The ``upload`` command no longer attaches an extra ``.zip`` when uploading
+   eggs, as PyPI now supports egg uploads without trickery.
+
+ * The ``ez_setup`` script/module now displays a warning before downloading
+   the setuptools egg, and attempts to check the downloaded egg against an
+   internal MD5 checksum table.
+
+ * Fixed the ``--tag-svn-revision`` option of ``egg_info`` not finding the
+   latest revision number; it was using the revision number of the directory
+   containing ``setup.py``, not the highest revision number in the project.
+
+ * Added ``eager_resources`` setup argument
+
+ * The ``sdist`` command now recognizes Subversion "deleted file" entries and
+   does not include them in source distributions.
+
+ * ``setuptools`` now embeds itself more thoroughly into the distutils, so that
+   other distutils extensions (e.g. py2exe, py2app) will subclass setuptools'
+   versions of things, rather than the native distutils ones.
+
+ * Added ``entry_points`` and ``setup_requires`` arguments to ``setup()``;
+   ``setup_requires`` allows you to automatically find and download packages
+   that are needed in order to *build* your project (as opposed to running it).
+
+ * ``setuptools`` now finds its commands, ``setup()`` argument validators, and
+   metadata writers using entry points, so that they can be extended by
+   third-party packages.  See `Creating distutils Extensions
+   <http://pythonhosted.org/setuptools/setuptools.html#creating-distutils-extensions>`_
+   for more details.
+
+ * The vestigial ``depends`` command has been removed.  It was never finished
+   or documented, and never would have worked without EasyInstall - which it
+   pre-dated and was never compatible with.
+
+------
+0.5a12
+------
+
+ * The zip-safety scanner now checks for modules that might be used with
+   ``python -m``, and marks them as unsafe for zipping, since Python 2.4 can't
+   handle ``-m`` on zipped modules.
+
+------
+0.5a11
+------
+
+ * Fix breakage of the "develop" command that was caused by the addition of
+   ``--always-unzip`` to the ``easy_install`` command.
+
+-----
+0.5a9
+-----
+
+ * Include ``svn:externals`` directories in source distributions as well as
+   normal subversion-controlled files and directories.
+
+ * Added ``exclude=patternlist`` option to ``setuptools.find_packages()``
+
+ * Changed --tag-svn-revision to include an "r" in front of the revision number
+   for better readability.
+
+ * Added ability to build eggs without including source files (except for any
+   scripts, of course), using the ``--exclude-source-files`` option to
+   ``bdist_egg``.
+
+ * ``setup.py install`` now automatically detects when an "unmanaged" package
+   or module is going to be on ``sys.path`` ahead of a package being installed,
+   thereby preventing the newer version from being imported.  If this occurs,
+   a warning message is output to ``sys.stderr``, but installation proceeds
+   anyway.  The warning message informs the user what files or directories
+   need deleting, and advises them they can also use EasyInstall (with the
+   ``--delete-conflicting`` option) to do it automatically.
+
+ * The ``egg_info`` command now adds a ``top_level.txt`` file to the metadata
+   directory that lists all top-level modules and packages in the distribution.
+   This is used by the ``easy_install`` command to find possibly-conflicting
+   "unmanaged" packages when installing the distribution.
+
+ * Added ``zip_safe`` and ``namespace_packages`` arguments to ``setup()``.
+   Added package analysis to determine zip-safety if the ``zip_safe`` flag
+   is not given, and advise the author regarding what code might need changing.
+
+ * Fixed the swapped ``-d`` and ``-b`` options of ``bdist_egg``.
+
+-----
+0.5a8
+-----
+
+ * The "egg_info" command now always sets the distribution metadata to "safe"
+   forms of the distribution name and version, so that distribution files will
+   be generated with parseable names (i.e., ones that don't include '-' in the
+   name or version).  Also, this means that if you use the various ``--tag``
+   options of "egg_info", any distributions generated will use the tags in the
+   version, not just egg distributions.
+
+ * Added support for defining command aliases in distutils configuration files,
+   under the "[aliases]" section.  To prevent recursion and to allow aliases to
+   call the command of the same name, a given alias can be expanded only once
+   per command-line invocation.  You can define new aliases with the "alias"
+   command, either for the local, global, or per-user configuration.
+
+ * Added "rotate" command to delete old distribution files, given a set of
+   patterns to match and the number of files to keep.  (Keeps the most
+   recently-modified distribution files matching each pattern.)
+
+ * Added "saveopts" command that saves all command-line options for the current
+   invocation to the local, global, or per-user configuration file.  Useful for
+   setting defaults without having to hand-edit a configuration file.
+
+ * Added a "setopt" command that sets a single option in a specified distutils
+   configuration file.
+
+-----
+0.5a7
+-----
+
+ * Added "upload" support for egg and source distributions, including a bug
+   fix for "upload" and a temporary workaround for lack of .egg support in
+   PyPI.
+
+-----
+0.5a6
+-----
+
+ * Beefed up the "sdist" command so that if you don't have a MANIFEST.in, it
+   will include all files under revision control (CVS or Subversion) in the
+   current directory, and it will regenerate the list every time you create a
+   source distribution, not just when you tell it to.  This should make the
+   default "do what you mean" more often than the distutils' default behavior
+   did, while still retaining the old behavior in the presence of MANIFEST.in.
+
+ * Fixed the "develop" command always updating .pth files, even if you
+   specified ``-n`` or ``--dry-run``.
+
+ * Slightly changed the format of the generated version when you use
+   ``--tag-build`` on the "egg_info" command, so that you can make tagged
+   revisions compare *lower* than the version specified in setup.py (e.g. by
+   using ``--tag-build=dev``).
+
+-----
+0.5a5
+-----
+
+ * Added ``develop`` command to ``setuptools``-based packages.  This command
+   installs an ``.egg-link`` pointing to the package's source directory, and
+   script wrappers that ``execfile()`` the source versions of the package's
+   scripts.  This lets you put your development checkout(s) on sys.path without
+   having to actually install them.  (To uninstall the link, use
+   use ``setup.py develop --uninstall``.)
+
+ * Added ``egg_info`` command to ``setuptools``-based packages.  This command
+   just creates or updates the "projectname.egg-info" directory, without
+   building an egg.  (It's used by the ``bdist_egg``, ``test``, and ``develop``
+   commands.)
+
+ * Enhanced the ``test`` command so that it doesn't install the package, but
+   instead builds any C extensions in-place, updates the ``.egg-info``
+   metadata, adds the source directory to ``sys.path``, and runs the tests
+   directly on the source.  This avoids an "unmanaged" installation of the
+   package to ``site-packages`` or elsewhere.
+
+ * Made ``easy_install`` a standard ``setuptools`` command, moving it from
+   the ``easy_install`` module to ``setuptools.command.easy_install``.  Note
+   that if you were importing or extending it, you must now change your imports
+   accordingly.  ``easy_install.py`` is still installed as a script, but not as
+   a module.
+
+-----
+0.5a4
+-----
+
+ * Setup scripts using setuptools can now list their dependencies directly in
+   the setup.py file, without having to manually create a ``depends.txt`` file.
+   The ``install_requires`` and ``extras_require`` arguments to ``setup()``
+   are used to create a dependencies file automatically.  If you are manually
+   creating ``depends.txt`` right now, please switch to using these setup
+   arguments as soon as practical, because ``depends.txt`` support will be
+   removed in the 0.6 release cycle.  For documentation on the new arguments,
+   see the ``setuptools.dist.Distribution`` class.
+
+ * Setup scripts using setuptools now always install using ``easy_install``
+   internally, for ease of uninstallation and upgrading.
+
+-----
+0.5a1
+-----
+
+ * Added support for "self-installation" bootstrapping.  Packages can now
+   include ``ez_setup.py`` in their source distribution, and add the following
+   to their ``setup.py``, in order to automatically bootstrap installation of
+   setuptools as part of their setup process::
+
+    from ez_setup import use_setuptools
+    use_setuptools()
+
+    from setuptools import setup
+    # etc...
+
+-----
+0.4a2
+-----
+
+ * Added ``ez_setup.py`` installer/bootstrap script to make initial setuptools
+   installation easier, and to allow distributions using setuptools to avoid
+   having to include setuptools in their source distribution.
+
+ * All downloads are now managed by the ``PackageIndex`` class (which is now
+   subclassable and replaceable), so that embedders can more easily override
+   download logic, give download progress reports, etc.  The class has also
+   been moved to the new ``setuptools.package_index`` module.
+
+ * The ``Installer`` class no longer handles downloading, manages a temporary
+   directory, or tracks the ``zip_ok`` option.  Downloading is now handled
+   by ``PackageIndex``, and ``Installer`` has become an ``easy_install``
+   command class based on ``setuptools.Command``.
+
+ * There is a new ``setuptools.sandbox.run_setup()`` API to invoke a setup
+   script in a directory sandbox, and a new ``setuptools.archive_util`` module
+   with an ``unpack_archive()`` API.  These were split out of EasyInstall to
+   allow reuse by other tools and applications.
+
+ * ``setuptools.Command`` now supports reinitializing commands using keyword
+   arguments to set/reset options.  Also, ``Command`` subclasses can now set
+   their ``command_consumes_arguments`` attribute to ``True`` in order to
+   receive an ``args`` option containing the rest of the command line.
+
+-----
+0.3a2
+-----
+
+ * Added new options to ``bdist_egg`` to allow tagging the egg's version number
+   with a subversion revision number, the current date, or an explicit tag
+   value.  Run ``setup.py bdist_egg --help`` to get more information.
+
+ * Misc. bug fixes
+
+-----
+0.3a1
+-----
+
+ * Initial release.

+Installing and Using Setuptools
+===============================
+
+.. contents:: **Table of Contents**
+
+
+-------------------------
+Installation Instructions
+-------------------------
+
+The recommended way to bootstrap setuptools on any system is to download
+`ez_setup.py`_ and run it using the target Python environment. Different
+operating systems have different recommended techniques to accomplish this
+basic routine, so below are some examples to get you started.
+
+Setuptools requires Python 2.6 or later. To install setuptools
+on Python 2.4 or Python 2.5, use the `bootstrap script for Setuptools 1.x
+<https://bitbucket.org/pypa/setuptools/raw/bootstrap-py24/ez_setup.py>`_.
+
+The link provided to ez_setup.py is a bookmark to bootstrap script for the
+latest known stable release.
+
+.. _ez_setup.py: https://bootstrap.pypa.io/ez_setup.py
+
+Windows (Powershell 3 or later)
+===============================
+
+For best results, uninstall previous versions FIRST (see `Uninstalling`_).
+
+Using Windows 8 (which includes PowerShell 3) or earlier versions of Windows
+with PowerShell 3 installed, it's possible to install with one simple
+Powershell command. Start up Powershell and paste this command::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python -
+
+You must start the Powershell with Administrative privileges or you may choose
+to install a user-local installation::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python - --user
+
+If you have Python 3.3 or later, you can use the ``py`` command to install to
+different Python versions. For example, to install to Python 3.3 if you have
+Python 2.7 installed::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | py -3 -
+
+The recommended way to install setuptools on Windows is to download
+`ez_setup.py`_ and run it. The script will download the appropriate
+distribution file and install it for you.
+
+Once installation is complete, you will find an ``easy_install`` program in
+your Python ``Scripts`` subdirectory.  For simple invocation and best results,
+add this directory to your ``PATH`` environment variable, if it is not already
+present. If you did a user-local install, the ``Scripts`` subdirectory is
+``$env:APPDATA\Python\Scripts``.
+
+
+Windows (simplified)
+====================
+
+For Windows without PowerShell 3 or for installation without a command-line,
+download `ez_setup.py`_ using your preferred web browser or other technique
+and "run" that file.
+
+
+Unix (wget)
+===========
+
+Most Linux distributions come with wget.
+
+Download `ez_setup.py`_ and run it using the target Python version. The script
+will download the appropriate version and install it for you::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | python
+
+Note that you will may need to invoke the command with superuser privileges to
+install to the system Python::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
+
+Alternatively, Setuptools may be installed to a user-local path::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | python - --user
+
+Unix including Mac OS X (curl)
+==============================
+
+If your system has curl installed, follow the ``wget`` instructions but
+replace ``wget`` with ``curl`` and ``-O`` with ``-o``. For example::
+
+    > curl https://bootstrap.pypa.io/ez_setup.py -o - | python
+
+
+Advanced Installation
+=====================
+
+For more advanced installation options, such as installing to custom
+locations or prefixes, download and extract the source
+tarball from `Setuptools on PyPI <https://pypi.python.org/pypi/setuptools>`_
+and run setup.py with any supported distutils and Setuptools options.
+For example::
+
+    setuptools-x.x$ python setup.py install --prefix=/opt/setuptools
+
+Use ``--help`` to get a full options list, but we recommend consulting
+the `EasyInstall manual`_ for detailed instructions, especially `the section
+on custom installation locations`_.
+
+.. _EasyInstall manual: https://pythonhosted.org/setuptools/EasyInstall
+.. _the section on custom installation locations: https://pythonhosted.org/setuptools/EasyInstall#custom-installation-locations
+
+
+Downloads
+=========
+
+All setuptools downloads can be found at `the project's home page in the Python
+Package Index`_.  Scroll to the very bottom of the page to find the links.
+
+.. _the project's home page in the Python Package Index: https://pypi.python.org/pypi/setuptools
+
+In addition to the PyPI downloads, the development version of ``setuptools``
+is available from the `Bitbucket repo`_, and in-development versions of the
+`0.6 branch`_ are available as well.
+
+.. _Bitbucket repo: https://bitbucket.org/pypa/setuptools/get/default.tar.gz#egg=setuptools-dev
+.. _0.6 branch: http://svn.python.org/projects/sandbox/branches/setuptools-0.6/#egg=setuptools-dev06
+
+Uninstalling
+============
+
+On Windows, if Setuptools was installed using an ``.exe`` or ``.msi``
+installer, simply use the uninstall feature of "Add/Remove Programs" in the
+Control Panel.
+
+Otherwise, to uninstall Setuptools or Distribute, regardless of the Python
+version, delete all ``setuptools*`` and ``distribute*`` files and
+directories from your system's ``site-packages`` directory
+(and any other ``sys.path`` directories) FIRST.
+
+If you are upgrading or otherwise plan to re-install Setuptools or Distribute,
+nothing further needs to be done. If you want to completely remove Setuptools,
+you may also want to remove the 'easy_install' and 'easy_install-x.x' scripts
+and associated executables installed to the Python scripts directory.
+

+
+* The original design for the ``.egg`` format and the ``pkg_resources`` API was
+  co-created by Phillip Eby and Bob Ippolito.  Bob also implemented the first
+  version of ``pkg_resources``, and supplied the OS X operating system version
+  compatibility algorithm.
+
+* Ian Bicking implemented many early "creature comfort" features of
+  easy_install, including support for downloading via Sourceforge and
+  Subversion repositories.  Ian's comments on the Web-SIG about WSGI
+  application deployment also inspired the concept of "entry points" in eggs,
+  and he has given talks at PyCon and elsewhere to inform and educate the
+  community about eggs and setuptools.
+
+* Jim Fulton contributed time and effort to build automated tests of various
+  aspects of ``easy_install``, and supplied the doctests for the command-line
+  ``.exe`` wrappers on Windows.
+
+* Phillip J. Eby is the seminal author of setuptools, and
+  first proposed the idea of an importable binary distribution format for
+  Python application plug-ins.
+
+* Significant parts of the implementation of setuptools were funded by the Open
+  Source Applications Foundation, to provide a plug-in infrastructure for the
+  Chandler PIM application.  In addition, many OSAF staffers (such as Mike
+  "Code Bear" Taylor) contributed their time and stress as guinea pigs for the
+  use of eggs and setuptools, even before eggs were "cool".  (Thanks, guys!)
+
+* Tarek Ziadé is the principal author of the Distribute fork, which
+  re-invigorated the community on the project, encouraged renewed innovation,
+  and addressed many defects.
+
+* Since the merge with Distribute, Jason R. Coombs is the
+  maintainer of setuptools.  The project is maintained in coordination with
+  the Python Packaging Authority (PyPA) and the larger Python community.

+CHANGES
+=======
+
+-----
+6.0.2
+-----
+
+* `Issue #262 <https://bitbucket.org/pypa/setuptools/issue/262>`_: Fixed regression in pip install due to egg-info directories
+  being omitted. Re-opens `Issue #118 <https://bitbucket.org/pypa/setuptools/issue/118>`_.
+
+-----
+6.0.1
+-----
+
+* `Issue #259 <https://bitbucket.org/pypa/setuptools/issue/259>`_: Fixed regression with namespace package handling on ``single
+  version, externally managed`` installs.
+
+---
+6.0
+---
+
+* `Issue #100 <https://bitbucket.org/pypa/setuptools/issue/100>`_: When building a distribution, Setuptools will no longer match
+  default files using platform-dependent case sensitivity, but rather will
+  only match the files if their case matches exactly. As a result, on Windows
+  and other case-insensitive file systems, files with names such as
+  'readme.txt' or 'README.TXT' will be omitted from the distribution and a
+  warning will be issued indicating that 'README.txt' was not found. Other
+  filenames affected are:
+
+    - README.rst
+    - README
+    - setup.cfg
+    - setup.py (or the script name)
+    - test/test*.py
+
+  Any users producing distributions with filenames that match those above
+  case-insensitively, but not case-sensitively, should rename those files in
+  their repository for better portability.
+* `Pull Request #72 <https://bitbucket.org/pypa/setuptools/pull-request/72>`_: When using ``single_version_externally_managed``, the
+  exclusion list now includes Python 3.2 ``__pycache__`` entries.
+* `Pull Request #76 <https://bitbucket.org/pypa/setuptools/pull-request/76>`_ and `Pull Request #78 <https://bitbucket.org/pypa/setuptools/pull-request/78>`_: lines in top_level.txt are now
+  ordered deterministically.
+* `Issue #118 <https://bitbucket.org/pypa/setuptools/issue/118>`_: The egg-info directory is now no longer included in the list
+  of outputs.
+* `Issue #258 <https://bitbucket.org/pypa/setuptools/issue/258>`_: Setuptools now patches distutils msvc9compiler to
+  recognize the specially-packaged compiler package for easy extension module
+  support on Python 2.6, 2.7, and 3.2.
+
+---
+5.8
+---
+
+* `Issue #237 <https://bitbucket.org/pypa/setuptools/issue/237>`_: ``pkg_resources`` now uses explicit detection of Python 2 vs.
+  Python 3, supporting environments where builtins have been patched to make
+  Python 3 look more like Python 2.
+
+---
+5.7
+---
+
+* `Issue #240 <https://bitbucket.org/pypa/setuptools/issue/240>`_: Based on real-world performance measures against 5.4, zip
+  manifests are now cached in all circumstances. The
+  ``PKG_RESOURCES_CACHE_ZIP_MANIFESTS`` environment variable is no longer
+  relevant. The observed "memory increase" referenced in the 5.4 release
+  notes and detailed in `Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154>`_ was likely not an increase over the status
+  quo, but rather only an increase over not storing the zip info at all.
+
+---
+5.6
+---
+
+* `Issue #242 <https://bitbucket.org/pypa/setuptools/issue/242>`_: Use absolute imports in svn_utils to avoid issues if the
+  installing package adds an xml module to the path.
+
+-----
+5.5.1
+-----
+
+* `Issue #239 <https://bitbucket.org/pypa/setuptools/issue/239>`_: Fix typo in 5.5 such that fix did not take.
+
+---
+5.5
+---
+
+* `Issue #239 <https://bitbucket.org/pypa/setuptools/issue/239>`_: Setuptools now includes the setup_requires directive on
+  Distribution objects and validates the syntax just like install_requires
+  and tests_require directives.
+
+-----
+5.4.2
+-----
+
+* `Issue #236 <https://bitbucket.org/pypa/setuptools/issue/236>`_: Corrected regression in execfile implementation for Python 2.6.
+
+-----
+5.4.1
+-----
+
+* `Python #7776 <http://bugs.python.org/issue7776>`_: (ssl_support) Correct usage of host for validation when
+  tunneling for HTTPS.
+
+---
+5.4
+---
+
+* `Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154>`_: ``pkg_resources`` will now cache the zip manifests rather than
+  re-processing the same file from disk multiple times, but only if the
+  environment variable ``PKG_RESOURCES_CACHE_ZIP_MANIFESTS`` is set. Clients
+  that package many modules in the same zip file will see some improvement
+  in startup time by enabling this feature. This feature is not enabled by
+  default because it causes a substantial increase in memory usage.
+
+---
+5.3
+---
+
+* `Issue #185 <https://bitbucket.org/pypa/setuptools/issue/185>`_: Make svn tagging work on the new style SVN metadata.
+  Thanks cazabon!
+* Prune revision control directories (e.g .svn) from base path
+  as well as sub-directories.
+
+---
+5.2
+---
+
+* Added a `Developer Guide
+  <https://pythonhosted.org/setuptools/developer-guide.html>`_ to the official
+  documentation.
+* Some code refactoring and cleanup was done with no intended behavioral
+  changes.
+* During install_egg_info, the generated lines for namespace package .pth
+  files are now processed even during a dry run.
+
+---
+5.1
+---
+
+* `Issue #202 <https://bitbucket.org/pypa/setuptools/issue/202>`_: Implemented more robust cache invalidation for the ZipImporter,
+  building on the work in `Issue #168 <https://bitbucket.org/pypa/setuptools/issue/168>`_. Special thanks to Jurko Gospodnetic and
+  PJE.
+
+-----
+5.0.2
+-----
+
+* `Issue #220 <https://bitbucket.org/pypa/setuptools/issue/220>`_: Restored script templates.
+
+-----
+5.0.1
+-----
+
+* Renamed script templates to end with .tmpl now that they no longer need
+  to be processed by 2to3. Fixes spurious syntax errors during build/install.
+
+---
+5.0
+---
+
+* `Issue #218 <https://bitbucket.org/pypa/setuptools/issue/218>`_: Re-release of 3.8.1 to signal that it supersedes 4.x.

+* `Issue #218 <https://bitbucket.org/pypa/setuptools/issue/218>`_: Setuptools 3.8.1 superseded 4.0.1, and 4.x was removed
+  from the available versions to install.
+
+---
+4.0
+---
+
+* `Issue #210 <https://bitbucket.org/pypa/setuptools/issue/210>`_: ``setup.py develop`` now copies scripts in binary mode rather
+  than text mode, matching the behavior of the ``install`` command.
+
+---
+3.8
+---
+
+* Extend `Issue #197 <https://bitbucket.org/pypa/setuptools/issue/197>`_ workaround to include all Python 3 versions prior to
+  3.2.2.
+
+---
+3.7
+---
+
+* `Issue #193 <https://bitbucket.org/pypa/setuptools/issue/193>`_: Improved handling of Unicode filenames when building manifests.
+

+  broken in 3.4).
+* `Issue #197 <https://bitbucket.org/pypa/setuptools/issue/197>`_: On Python 3.1, PKG-INFO is now saved in a UTF-8 encoding instead
+  of ``sys.getpreferredencoding`` to match the behavior on Python 2.6-3.4.
+* `Issue #192 <https://bitbucket.org/pypa/setuptools/issue/192>`_: Preferred bootstrap location is now
+  https://bootstrap.pypa.io/ez_setup.py (mirrored from former location).
+
+-----
+3.4.4
+-----
+
+* `Issue #184 <https://bitbucket.org/pypa/setuptools/issue/184>`_: Correct failure where find_package over-matched packages
+  when directory traversal isn't short-circuited.
+
+-----
+3.4.3
+-----
+
+* `Issue #183 <https://bitbucket.org/pypa/setuptools/issue/183>`_: Really fix test command with Python 3.1.
+
+-----
+3.4.2
+-----
+
+* `Issue #183 <https://bitbucket.org/pypa/setuptools/issue/183>`_: Fix additional regression in test command on Python 3.1.
+
+-----
+3.4.1
+-----
+
+* `Issue #180 <https://bitbucket.org/pypa/setuptools/issue/180>`_: Fix regression in test command not caught by py.test-run tests.
+
+---
+3.4
+---
+
+* `Issue #176 <https://bitbucket.org/pypa/setuptools/issue/176>`_: Add parameter to the test command to support a custom test
+  runner: --test-runner or -r.
+* `Issue #177 <https://bitbucket.org/pypa/setuptools/issue/177>`_: Now assume most common invocation to install command on
+  platforms/environments without stack support (issuing a warning). Setuptools
+  now installs naturally on IronPython. Behavior on CPython should be
+  unchanged.
+
+---
+3.3
+---
+
+* Add ``include`` parameter to ``setuptools.find_packages()``.
+
+---
+3.2
+---
+
+* `Pull Request #39 <https://bitbucket.org/pypa/setuptools/pull-request/39>`_: Add support for C++ targets from Cython ``.pyx`` files.
+* `Issue #162 <https://bitbucket.org/pypa/setuptools/issue/162>`_: Update dependency on certifi to 1.0.1.
+* `Issue #164 <https://bitbucket.org/pypa/setuptools/issue/164>`_: Update dependency on wincertstore to 0.2.
+
+---
+3.1
+---
+
+* `Issue #161 <https://bitbucket.org/pypa/setuptools/issue/161>`_: Restore Features functionality to allow backward compatibility
+  (for Features) until the uses of that functionality is sufficiently removed.
+
+-----
+3.0.2
+-----
+
+* Correct typo in previous bugfix.
+
+-----
+3.0.1
+-----
+
+* `Issue #157 <https://bitbucket.org/pypa/setuptools/issue/157>`_: Restore support for Python 2.6 in bootstrap script where
+  ``zipfile.ZipFile`` does not yet have support for context managers.
+
+---
+3.0
+---
+
+* `Issue #125 <https://bitbucket.org/pypa/setuptools/issue/125>`_: Prevent Subversion support from creating a ~/.subversion
+  directory just for checking the presence of a Subversion repository.
+* `Issue #12 <https://bitbucket.org/pypa/setuptools/issue/12>`_: Namespace packages are now imported lazily.  That is, the mere
+  declaration of a namespace package in an egg on ``sys.path`` no longer
+  causes it to be imported when ``pkg_resources`` is imported.  Note that this
+  change means that all of a namespace package's ``__init__.py`` files must
+  include a ``declare_namespace()`` call in order to ensure that they will be
+  handled properly at runtime.  In 2.x it was possible to get away without
+  including the declaration, but only at the cost of forcing namespace
+  packages to be imported early, which 3.0 no longer does.
+* `Issue #148 <https://bitbucket.org/pypa/setuptools/issue/148>`_: When building (bdist_egg), setuptools no longer adds
+  ``__init__.py`` files to namespace packages. Any packages that rely on this
+  behavior will need to create ``__init__.py`` files and include the
+  ``declare_namespace()``.
+* `Issue #7 <https://bitbucket.org/pypa/setuptools/issue/7>`_: Setuptools itself is now distributed as a zip archive in addition to
+  tar archive. ez_setup.py now uses zip archive. This approach avoids the potential
+  security vulnerabilities presented by use of tar archives in ez_setup.py.
+  It also leverages the security features added to ZipFile.extract in Python 2.7.4.
+* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Removed deprecated Features functionality.
+* `Pull Request #28 <https://bitbucket.org/pypa/setuptools/pull-request/28>`_: Remove backport of ``_bytecode_filenames`` which is
+  available in Python 2.6 and later, but also has better compatibility with
+  Python 3 environments.
+* `Issue #156 <https://bitbucket.org/pypa/setuptools/issue/156>`_: Fix spelling of __PYVENV_LAUNCHER__ variable.
+
+---
+2.2
+---
+
+* `Issue #141 <https://bitbucket.org/pypa/setuptools/issue/141>`_: Restored fix for allowing setup_requires dependencies to
+  override installed dependencies during setup.
+* `Issue #128 <https://bitbucket.org/pypa/setuptools/issue/128>`_: Fixed issue where only the first dependency link was honored
+  in a distribution where multiple dependency links were supplied.
+
+-----
+2.1.2
+-----
+
+* `Issue #144 <https://bitbucket.org/pypa/setuptools/issue/144>`_: Read long_description using codecs module to avoid errors
+  installing on systems where LANG=C.
+

+2.1.1
+-----
+
+* `Issue #139 <https://bitbucket.org/pypa/setuptools/issue/139>`_: Fix regression in re_finder for CVS repos (and maybe Git repos
+  as well).
+
+---
+2.1
+---
+
+* `Issue #129 <https://bitbucket.org/pypa/setuptools/issue/129>`_: Suppress inspection of ``*.whl`` files when searching for files

+* `Issue #131 <https://bitbucket.org/pypa/setuptools/issue/131>`_: Fix RuntimeError when constructing an egg fetcher.
+
+-----
+2.0.2
+-----
+
+* Fix NameError during installation with Python implementations (e.g. Jython)
+  not containing parser module.
+* Fix NameError in ``sdist:re_finder``.
+
+-----
+2.0.1
+-----
+
+* `Issue #124 <https://bitbucket.org/pypa/setuptools/issue/124>`_: Fixed error in list detection in upload_docs.
+
+---
+2.0
+---
+
+* `Issue #121 <https://bitbucket.org/pypa/setuptools/issue/121>`_: Exempt lib2to3 pickled grammars from DirectorySandbox.
+* `Issue #41 <https://bitbucket.org/pypa/setuptools/issue/41>`_: Dropped support for Python 2.4 and Python 2.5. Clients requiring
+  setuptools for those versions of Python should use setuptools 1.x.
+* Removed ``setuptools.command.easy_install.HAS_USER_SITE``. Clients
+  expecting this boolean variable should use ``site.ENABLE_USER_SITE``
+  instead.
+* Removed ``pkg_resources.ImpWrapper``. Clients that expected this class
+  should use ``pkgutil.ImpImporter`` instead.

+
+* `Issue #105 <https://bitbucket.org/pypa/setuptools/issue/105>`_ and `Issue #113 <https://bitbucket.org/pypa/setuptools/issue/113>`_: Establish a more robust technique for
+  determining the terminal encoding::
+
+    1. Try ``getpreferredencoding``
+    2. If that returns US_ASCII or None, try the encoding from
+       ``getdefaultlocale``. If that encoding was a "fallback" because Python
+       could not figure it out from the environment or OS, encoding remains
+       unresolved.
+    3. If the encoding is resolved, then make sure Python actually implements
+       the encoding.
+    4. On the event of an error or unknown codec, revert to fallbacks
+       (UTF-8 on Darwin, ASCII on everything else).
+    5. On the encoding is 'mac-roman' on Darwin, use UTF-8 as 'mac-roman' was
+       a bug on older Python releases.
+
+    On a side note, it would seem that the encoding only matters for when SVN
+    does not yet support ``--xml`` and when getting repository and svn version
+    numbers. The ``--xml`` technique should yield UTF-8 according to some
+    messages on the SVN mailing lists. So if the version numbers are always
+    7-bit ASCII clean, it may be best to only support the file parsing methods
+    for legacy SVN releases and support for SVN without the subprocess command
+    would simple go away as support for the older SVNs does.
+

+1.4
+---
+
+* `Issue #27 <https://bitbucket.org/pypa/setuptools/issue/27>`_: ``easy_install`` will now use credentials from .pypirc if
+  present for connecting to the package index.
+* `Pull Request #21 <https://bitbucket.org/pypa/setuptools/pull-request/21>`_: Omit unwanted newlines in ``package_index._encode_auth``
+  when the username/password pair length indicates wrapping.
+
+-----
+1.3.2
+-----
+
+* `Issue #99 <https://bitbucket.org/pypa/setuptools/issue/99>`_: Fix filename encoding issues in SVN support.
+

+
+---
+1.3
+---
+
+* Address security vulnerability in SSL match_hostname check as reported in
+  `Python #17997 <http://bugs.python.org/issue17997>`_.
+* Prefer `backports.ssl_match_hostname
+  <https://pypi.python.org/pypi/backports.ssl_match_hostname>`_ for backport
+  implementation if present.
+* Correct NameError in ``ssl_support`` module (``socket.error``).
+
+---
+1.2
+---
+
+* `Issue #26 <https://bitbucket.org/pypa/setuptools/issue/26>`_: Add support for SVN 1.7. Special thanks to Philip Thiem for the
+  contribution.
+* `Issue #93 <https://bitbucket.org/pypa/setuptools/issue/93>`_: Wheels are now distributed with every release. Note that as
+  reported in `Issue #108 <https://bitbucket.org/pypa/setuptools/issue/108>`_, as of Pip 1.4, scripts aren't installed properly
+  from wheels. Therefore, if using Pip to install setuptools from a wheel,
+  the ``easy_install`` command will not be available.
+* Setuptools "natural" launcher support, introduced in 1.0, is now officially
+  supported.
+
+-----
+1.1.7
+-----
+
+* Fixed behavior of NameError handling in 'script template (dev).py' (script
+  launcher for 'develop' installs).
+* ``ez_setup.py`` now ensures partial downloads are cleaned up following
+  a failed download.
+* `Distribute #363 <https://bitbucket.org/tarek/distribute/issue/363>`_ and `Issue #55 <https://bitbucket.org/pypa/setuptools/issue/55>`_: Skip an sdist test that fails on locales
+  other than UTF-8.
+
+-----
+1.1.6
+-----
+
+* `Distribute #349 <https://bitbucket.org/tarek/distribute/issue/349>`_: ``sandbox.execfile`` now opens the target file in binary
+  mode, thus honoring a BOM in the file when compiled.
+
+-----
+1.1.5
+-----
+
+* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Second attempt at fix (logic was reversed).
+
+-----
+1.1.4
+-----
+
+* `Issue #77 <https://bitbucket.org/pypa/setuptools/issue/77>`_: Fix error in upload command (Python 2.4).
+
+-----
+1.1.3
+-----
+
+* Fix NameError in previous patch.
+
+-----
+1.1.2
+-----
+
+* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Correct issue where 404 errors are returned for URLs with
+  fragments in them (such as #egg=).
+
+-----
+1.1.1
+-----
+
+* `Issue #75 <https://bitbucket.org/pypa/setuptools/issue/75>`_: Add ``--insecure`` option to ez_setup.py to accommodate
+  environments where a trusted SSL connection cannot be validated.
+* `Issue #76 <https://bitbucket.org/pypa/setuptools/issue/76>`_: Fix AttributeError in upload command with Python 2.4.
+
+---
+1.1
+---
+
+* `Issue #71 <https://bitbucket.org/pypa/setuptools/issue/71>`_ (`Distribute #333 <https://bitbucket.org/tarek/distribute/issue/333>`_): EasyInstall now puts less emphasis on the
+  condition when a host is blocked via ``--allow-hosts``.
+* `Issue #72 <https://bitbucket.org/pypa/setuptools/issue/72>`_: Restored Python 2.4 compatibility in ``ez_setup.py``.
+
+---
+1.0
+---
+
+* `Issue #60 <https://bitbucket.org/pypa/setuptools/issue/60>`_: On Windows, Setuptools supports deferring to another launcher,
+  such as Vinay Sajip's `pylauncher <https://bitbucket.org/pypa/pylauncher>`_
+  (included with Python 3.3) to launch console and GUI scripts and not install
+  its own launcher executables. This experimental functionality is currently
+  only enabled if  the ``SETUPTOOLS_LAUNCHER`` environment variable is set to
+  "natural". In the future, this behavior may become default, but only after
+  it has matured and seen substantial adoption. The ``SETUPTOOLS_LAUNCHER``
+  also accepts "executable" to force the default behavior of creating launcher
+  executables.
+* `Issue #63 <https://bitbucket.org/pypa/setuptools/issue/63>`_: Bootstrap script (ez_setup.py) now prefers Powershell, curl, or
+  wget for retrieving the Setuptools tarball for improved security of the
+  install. The script will still fall back to a simple ``urlopen`` on
+  platforms that do not have these tools.
+* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Deprecated the ``Features`` functionality.
+* `Issue #52 <https://bitbucket.org/pypa/setuptools/issue/52>`_: In ``VerifyingHTTPSConn``, handle a tunnelled (proxied)
+  connection.
+
+Backward-Incompatible Changes
+=============================
+
+This release includes a couple of backward-incompatible changes, but most if
+not all users will find 1.0 a drop-in replacement for 0.9.
+
+* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: Normalized API of environment marker support. Specifically,
+  removed line number and filename from SyntaxErrors when returned from
+  `pkg_resources.invalid_marker`. Any clients depending on the specific
+  string representation of exceptions returned by that function may need to
+  be updated to account for this change.
+* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: SyntaxErrors generated by `pkg_resources.invalid_marker` are
+  normalized for cross-implementation consistency.
+* Removed ``--ignore-conflicts-at-my-risk`` and ``--delete-conflicting``
+  options to easy_install. These options have been deprecated since 0.6a11.
+
+-----
+0.9.8
+-----
+
+* `Issue #53 <https://bitbucket.org/pypa/setuptools/issue/53>`_: Fix NameErrors in `_vcs_split_rev_from_url`.

+* `Issue #34 <https://bitbucket.org/pypa/setuptools/issue/34>`_: Documentation now refers to bootstrap script in code repository
+  referenced by bookmark.

+-----
+
+* `Issue #44 <https://bitbucket.org/pypa/setuptools/issue/44>`_: Test failure on Python 2.4 when MD5 hash doesn't have a `.name`

+-----
+
+* `Issue #42 <https://bitbucket.org/pypa/setuptools/issue/42>`_: Fix regression where blank checksums would trigger an
+  ``AttributeError``.
+
+-----
+0.9.1
+-----
+
+* `Distribute #386 <https://bitbucket.org/tarek/distribute/issue/386>`_: Allow other positional and keyword arguments to os.open.
+* Corrected dependency on certifi mis-referenced in 0.9.

+* `package_index` now validates hashes other than MD5 in download links.
+
+---
+0.8
+---
+
+* Code base now runs on Python 2.4 - Python 3.3 without Python 2to3
+  conversion.
+
+-----
+0.7.8
+-----
+
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Yet another fix for yet another regression.
+
+-----
+0.7.7
+-----
+
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Repair AttributeError created in last release (redo).

+
+-----
+0.7.5
+-----
+
+* `Issue #21 <https://bitbucket.org/pypa/setuptools/issue/21>`_: Restore Python 2.4 compatibility in ``test_easy_install``.
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Merged additional warning from Distribute 0.6.46.
+* Now honor the environment variable
+  ``SETUPTOOLS_DISABLE_VERSIONED_EASY_INSTALL_SCRIPT`` in addition to the now
+  deprecated ``DISTRIBUTE_DISABLE_VERSIONED_EASY_INSTALL_SCRIPT``.
+
+-----
+0.7.4
+-----
+
+* `Issue #20 <https://bitbucket.org/pypa/setuptools/issue/20>`_: Fix comparison of parsed SVN version on Python 3.
+
+-----
+0.7.3
+-----
+
+* `Issue #1 <https://bitbucket.org/pypa/setuptools/issue/1>`_: Disable installation of Windows-specific files on non-Windows systems.
+* Use new sysconfig module with Python 2.7 or >=3.2.
+
+-----
+0.7.2
+-----
+
+* `Issue #14 <https://bitbucket.org/pypa/setuptools/issue/14>`_: Use markerlib when the `parser` module is not available.
+* `Issue #10 <https://bitbucket.org/pypa/setuptools/issue/10>`_: ``ez_setup.py`` now uses HTTPS to download setuptools from PyPI.
+
+-----
+0.7.1
+-----
+
+* Fix NameError (`Issue #3 <https://bitbucket.org/pypa/setuptools/issue/3>`_) again - broken in bad merge.
+
+---
+0.7
+---
+
+* Merged Setuptools and Distribute. See docs/merge.txt for details.
+
+Added several features that were slated for setuptools 0.6c12:
+
+* Index URL now defaults to HTTPS.
+* Added experimental environment marker support. Now clients may designate a
+  PEP-426 environment marker for "extra" dependencies. Setuptools uses this
+  feature in ``setup.py`` for optional SSL and certificate validation support
+  on older platforms. Based on Distutils-SIG discussions, the syntax is
+  somewhat tentative. There should probably be a PEP with a firmer spec before
+  the feature should be considered suitable for use.
+* Added support for SSL certificate validation when installing packages from
+  an HTTPS service.
+
+-----
+0.7b4
+-----
+
+* `Issue #3 <https://bitbucket.org/pypa/setuptools/issue/3>`_: Fixed NameError in SSL support.
+
+------
+0.6.49
+------
+
+* Move warning check in ``get_cache_path`` to follow the directory creation
+  to avoid errors when the cache path does not yet exist. Fixes the error
+  reported in `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_.
+
+------
+0.6.48
+------
+
+* Correct AttributeError in ``ResourceManager.get_cache_path`` introduced in
+  0.6.46 (redo).
+
+------
+0.6.47
+------
+
+* Correct AttributeError in ``ResourceManager.get_cache_path`` introduced in
+  0.6.46.
+
+------
+0.6.46
+------
+
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Issue a warning if the PYTHON_EGG_CACHE or otherwise
+  customized egg cache location specifies a directory that's group- or
+  world-writable.
+
+------
+0.6.45
+------
+
+* `Distribute #379 <https://bitbucket.org/tarek/distribute/issue/379>`_: ``distribute_setup.py`` now traps VersionConflict as well,
+  restoring ability to upgrade from an older setuptools version.
+
+------
+0.6.44
+------
+
+* ``distribute_setup.py`` has been updated to allow Setuptools 0.7 to
+  satisfy use_setuptools.
+
+------
+0.6.43
+------
+
+* `Distribute #378 <https://bitbucket.org/tarek/distribute/issue/378>`_: Restore support for Python 2.4 Syntax (regression in 0.6.42).
+
+------
+0.6.42
+------
+
+* External links finder no longer yields duplicate links.
+* `Distribute #337 <https://bitbucket.org/tarek/distribute/issue/337>`_: Moved site.py to setuptools/site-patch.py (graft of very old
+  patch from setuptools trunk which inspired PR `#31 <https://bitbucket.org/pypa/setuptools/issue/31>`_).
+
+------
+0.6.41
+------
+
+* `Distribute #27 <https://bitbucket.org/tarek/distribute/issue/27>`_: Use public api for loading resources from zip files rather than
+  the private method `_zip_directory_cache`.
+* Added a new function ``easy_install.get_win_launcher`` which may be used by
+  third-party libraries such as buildout to get a suitable script launcher.
+
+------
+0.6.40
+------
+
+* `Distribute #376 <https://bitbucket.org/tarek/distribute/issue/376>`_: brought back cli.exe and gui.exe that were deleted in the
+  previous release.
+
+------
+0.6.39
+------
+
+* Add support for console launchers on ARM platforms.
+* Fix possible issue in GUI launchers where the subsystem was not supplied to
+  the linker.
+* Launcher build script now refactored for robustness.
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Resources extracted from a zip egg to the file system now also
+  check the contents of the file against the zip contents during each
+  invocation of get_resource_filename.
+
+------
+0.6.38
+------
+
+* `Distribute #371 <https://bitbucket.org/tarek/distribute/issue/371>`_: The launcher manifest file is now installed properly.
+
+------
+0.6.37
+------
+
+* `Distribute #143 <https://bitbucket.org/tarek/distribute/issue/143>`_: Launcher scripts, including easy_install itself, are now
+  accompanied by a manifest on 32-bit Windows environments to avoid the
+  Installer Detection Technology and thus undesirable UAC elevation described
+  in `this Microsoft article
+  <http://technet.microsoft.com/en-us/library/cc709628%28WS.10%29.aspx>`_.
+
+------
+0.6.36
+------
+
+* `Pull Request #35 <https://bitbucket.org/pypa/setuptools/pull-request/35>`_: In `Buildout #64 <https://github.com/buildout/buildout/issues/64>`_, it was reported that
+  under Python 3, installation of distutils scripts could attempt to copy
+  the ``__pycache__`` directory as a file, causing an error, apparently only
+  under Windows. Easy_install now skips all directories when processing
+  metadata scripts.
+
+------
+0.6.35
+------
+
+
+Note this release is backward-incompatible with distribute 0.6.23-0.6.34 in
+how it parses version numbers.
+
+* `Distribute #278 <https://bitbucket.org/tarek/distribute/issue/278>`_: Restored compatibility with distribute 0.6.22 and setuptools
+  0.6. Updated the documentation to match more closely with the version
+  parsing as intended in setuptools 0.6.
+
+------
+0.6.34
+------
+
+* `Distribute #341 <https://bitbucket.org/tarek/distribute/issue/341>`_: 0.6.33 fails to build under Python 2.4.
+
+------
+0.6.33
+------
+
+* Fix 2 errors with Jython 2.5.
+* Fix 1 failure with Jython 2.5 and 2.7.
+* Disable workaround for Jython scripts on Linux systems.
+* `Distribute #336 <https://bitbucket.org/tarek/distribute/issue/336>`_: `setup.py` no longer masks failure exit code when tests fail.
+* Fix issue in pkg_resources where try/except around a platform-dependent
+  import would trigger hook load failures on Mercurial. See pull request 32
+  for details.
+* `Distribute #341 <https://bitbucket.org/tarek/distribute/issue/341>`_: Fix a ResourceWarning.
+
+------
+0.6.32
+------
+
+* Fix test suite with Python 2.6.
+* Fix some DeprecationWarnings and ResourceWarnings.
+* `Distribute #335 <https://bitbucket.org/tarek/distribute/issue/335>`_: Backed out `setup_requires` superceding installed requirements
+  until regression can be addressed.
+
+------
+0.6.31
+------
+
+* `Distribute #303 <https://bitbucket.org/tarek/distribute/issue/303>`_: Make sure the manifest only ever contains UTF-8 in Python 3.
+* `Distribute #329 <https://bitbucket.org/tarek/distribute/issue/329>`_: Properly close files created by tests for compatibility with
+  Jython.
+* Work around `Jython #1980 <http://bugs.jython.org/issue1980>`_ and `Jython #1981 <http://bugs.jython.org/issue1981>`_.
+* `Distribute #334 <https://bitbucket.org/tarek/distribute/issue/334>`_: Provide workaround for packages that reference `sys.__stdout__`
+  such as numpy does. This change should address
+  `virtualenv `#359 <https://bitbucket.org/pypa/setuptools/issue/359>`_ <https://github.com/pypa/virtualenv/issues/359>`_ as long
+  as the system encoding is UTF-8 or the IO encoding is specified in the
+  environment, i.e.::
+
+     PYTHONIOENCODING=utf8 pip install numpy
+
+* Fix for encoding issue when installing from Windows executable on Python 3.
+* `Distribute #323 <https://bitbucket.org/tarek/distribute/issue/323>`_: Allow `setup_requires` requirements to supercede installed
+  requirements. Added some new keyword arguments to existing pkg_resources
+  methods. Also had to updated how __path__ is handled for namespace packages
+  to ensure that when a new egg distribution containing a namespace package is
+  placed on sys.path, the entries in __path__ are found in the same order they
+  would have been in had that egg been on the path when pkg_resources was
+  first imported.
+
+------
+0.6.30
+------
+
+* `Distribute #328 <https://bitbucket.org/tarek/distribute/issue/328>`_: Clean up temporary directories in distribute_setup.py.
+* Fix fatal bug in distribute_setup.py.
+
+------
+0.6.29
+------
+
+* `Pull Request #14 <https://bitbucket.org/pypa/setuptools/pull-request/14>`_: Honor file permissions in zip files.
+* `Distribute #327 <https://bitbucket.org/tarek/distribute/issue/327>`_: Merged pull request `#24 <https://bitbucket.org/pypa/setuptools/issue/24>`_ to fix a dependency problem with pip.
+* Merged pull request `#23 <https://bitbucket.org/pypa/setuptools/issue/23>`_ to fix https://github.com/pypa/virtualenv/issues/301.
+* If Sphinx is installed, the `upload_docs` command now runs `build_sphinx`
+  to produce uploadable documentation.
+* `Distribute #326 <https://bitbucket.org/tarek/distribute/issue/326>`_: `upload_docs` provided mangled auth credentials under Python 3.
+* `Distribute #320 <https://bitbucket.org/tarek/distribute/issue/320>`_: Fix check for "createable" in distribute_setup.py.
+* `Distribute #305 <https://bitbucket.org/tarek/distribute/issue/305>`_: Remove a warning that was triggered during normal operations.
+* `Distribute #311 <https://bitbucket.org/tarek/distribute/issue/311>`_: Print metadata in UTF-8 independent of platform.
+* `Distribute #303 <https://bitbucket.org/tarek/distribute/issue/303>`_: Read manifest file with UTF-8 encoding under Python 3.
+* `Distribute #301 <https://bitbucket.org/tarek/distribute/issue/301>`_: Allow to run tests of namespace packages when using 2to3.
+* `Distribute #304 <https://bitbucket.org/tarek/distribute/issue/304>`_: Prevent import loop in site.py under Python 3.3.
+* `Distribute #283 <https://bitbucket.org/tarek/distribute/issue/283>`_: Reenable scanning of `*.pyc` / `*.pyo` files on Python 3.3.
+* `Distribute #299 <https://bitbucket.org/tarek/distribute/issue/299>`_: The develop command didn't work on Python 3, when using 2to3,
+  as the egg link would go to the Python 2 source. Linking to the 2to3'd code
+  in build/lib makes it work, although you will have to rebuild the module
+  before testing it.
+* `Distribute #306 <https://bitbucket.org/tarek/distribute/issue/306>`_: Even if 2to3 is used, we build in-place under Python 2.
+* `Distribute #307 <https://bitbucket.org/tarek/distribute/issue/307>`_: Prints the full path when .svn/entries is broken.
+* `Distribute #313 <https://bitbucket.org/tarek/distribute/issue/313>`_: Support for sdist subcommands (Python 2.7)
+* `Distribute #314 <https://bitbucket.org/tarek/distribute/issue/314>`_: test_local_index() would fail an OS X.
+* `Distribute #310 <https://bitbucket.org/tarek/distribute/issue/310>`_: Non-ascii characters in a namespace __init__.py causes errors.
+* `Distribute #218 <https://bitbucket.org/tarek/distribute/issue/218>`_: Improved documentation on behavior of `package_data` and
+  `include_package_data`. Files indicated by `package_data` are now included
+  in the manifest.
+* `distribute_setup.py` now allows a `--download-base` argument for retrieving
+  distribute from a specified location.
+
+------
+0.6.28
+------
+
+* `Distribute #294 <https://bitbucket.org/tarek/distribute/issue/294>`_: setup.py can now be invoked from any directory.
+* Scripts are now installed honoring the umask.
+* Added support for .dist-info directories.
+* `Distribute #283 <https://bitbucket.org/tarek/distribute/issue/283>`_: Fix and disable scanning of `*.pyc` / `*.pyo` files on
+  Python 3.3.
+
+------
+0.6.27
+------
+
+* Support current snapshots of CPython 3.3.
+* Distribute now recognizes README.rst as a standard, default readme file.
+* Exclude 'encodings' modules when removing modules from sys.modules.
+  Workaround for `#285 <https://bitbucket.org/pypa/setuptools/issue/285>`_.

+  (bootstrap.py)
+
+------
+0.6.26
+------
+
+* `Distribute #183 <https://bitbucket.org/tarek/distribute/issue/183>`_: Symlinked files are now extracted from source distributions.
+* `Distribute #227 <https://bitbucket.org/tarek/distribute/issue/227>`_: Easy_install fetch parameters are now passed during the
+  installation of a source distribution; now fulfillment of setup_requires
+  dependencies will honor the parameters passed to easy_install.
+
+------
+0.6.25
+------
+
+* `Distribute #258 <https://bitbucket.org/tarek/distribute/issue/258>`_: Workaround a cache issue

+  can drive an installation that doesn't patch a global setuptools.
+* Reviewed unladen-swallow specific change from
+  http://code.google.com/p/unladen-swallow/source/detail?spec=svn875&r=719
+  and determined that it no longer applies. Distribute should work fine with
+  Unladen Swallow 2009Q3.

+  (patch by Holger Krekel)
+
+-----
+0.6.5

+
+-----
+0.6c9
+-----
+
+ * Fixed a missing files problem when using Windows source distributions on
+   non-Windows platforms, due to distutils not handling manifest file line
+   endings correctly.
+
+ * Updated Pyrex support to work with Pyrex 0.9.6 and higher.
+
+ * Minor changes for Jython compatibility, including skipping tests that can't
+   work on Jython.
+
+ * Fixed not installing eggs in ``install_requires`` if they were also used for
+   ``setup_requires`` or ``tests_require``.
+
+ * Fixed not fetching eggs in ``install_requires`` when running tests.
+
+ * Allow ``ez_setup.use_setuptools()`` to upgrade existing setuptools
+   installations when called from a standalone ``setup.py``.
+
+ * Added a warning if a namespace package is declared, but its parent package
+   is not also declared as a namespace.
+
+ * Support Subversion 1.5
+
+ * Removed use of deprecated ``md5`` module if ``hashlib`` is available
+
+ * Fixed ``bdist_wininst upload`` trying to upload the ``.exe`` twice
+
+ * Fixed ``bdist_egg`` putting a ``native_libs.txt`` in the source package's
+   ``.egg-info``, when it should only be in the built egg's ``EGG-INFO``.
+
+ * Ensure that _full_name is set on all shared libs before extensions are
+   checked for shared lib usage.  (Fixes a bug in the experimental shared
+   library build support.)
+
+ * Fix to allow unpacked eggs containing native libraries to fail more
+   gracefully under Google App Engine (with an ``ImportError`` loading the
+   C-based module, instead of getting a ``NameError``).
+
+-----
+0.6c7
+-----
+
+ * Fixed ``distutils.filelist.findall()`` crashing on broken symlinks, and
+   ``egg_info`` command failing on new, uncommitted SVN directories.
+
+ * Fix import problems with nested namespace packages installed via
+   ``--root`` or ``--single-version-externally-managed``, due to the
+   parent package not having the child package as an attribute.
+
+-----
+0.6c6
+-----
+
+ * Added ``--egg-path`` option to ``develop`` command, allowing you to force
+   ``.egg-link`` files to use relative paths (allowing them to be shared across
+   platforms on a networked drive).
+
+ * Fix not building binary RPMs correctly.
+
+ * Fix "eggsecutables" (such as setuptools' own egg) only being runnable with
+   bash-compatible shells.
+
+ * Fix ``#!`` parsing problems in Windows ``.exe`` script wrappers, when there
+   was whitespace inside a quoted argument or at the end of the ``#!`` line
+   (a regression introduced in 0.6c4).
+
+ * Fix ``test`` command possibly failing if an older version of the project
+   being tested was installed on ``sys.path`` ahead of the test source
+   directory.
+
+ * Fix ``find_packages()`` treating ``ez_setup`` and directories with ``.`` in
+   their names as packages.
+
+-----
+0.6c5
+-----
+
+ * Fix uploaded ``bdist_rpm`` packages being described as ``bdist_egg``
+   packages under Python versions less than 2.5.
+
+ * Fix uploaded ``bdist_wininst`` packages being described as suitable for
+   "any" version by Python 2.5, even if a ``--target-version`` was specified.
+
+-----
+0.6c4
+-----
+
+ * Overhauled Windows script wrapping to support ``bdist_wininst`` better.
+   Scripts installed with ``bdist_wininst`` will always use ``#!python.exe`` or
+   ``#!pythonw.exe`` as the executable name (even when built on non-Windows
+   platforms!), and the wrappers will look for the executable in the script's
+   parent directory (which should find the right version of Python).
+
+ * Fix ``upload`` command not uploading files built by ``bdist_rpm`` or
+   ``bdist_wininst`` under Python 2.3 and 2.4.
+
+ * Add support for "eggsecutable" headers: a ``#!/bin/sh`` script that is
+   prepended to an ``.egg`` file to allow it to be run as a script on Unix-ish
+   platforms.  (This is mainly so that setuptools itself can have a single-file
+   installer on Unix, without doing multiple downloads, dealing with firewalls,
+   etc.)
+
+ * Fix problem with empty revision numbers in Subversion 1.4 ``entries`` files
+
+ * Use cross-platform relative paths in ``easy-install.pth`` when doing
+   ``develop`` and the source directory is a subdirectory of the installation
+   target directory.
+
+ * Fix a problem installing eggs with a system packaging tool if the project
+   contained an implicit namespace package; for example if the ``setup()``
+   listed a namespace package ``foo.bar`` without explicitly listing ``foo``
+   as a namespace package.
+
+-----
+0.6c3
+-----
+
+ * Fixed breakages caused by Subversion 1.4's new "working copy" format
+
+-----
+0.6c2
+-----
+
+ * The ``ez_setup`` module displays the conflicting version of setuptools (and
+   its installation location) when a script requests a version that's not
+   available.
+
+ * Running ``setup.py develop`` on a setuptools-using project will now install
+   setuptools if needed, instead of only downloading the egg.
+
+-----
+0.6c1
+-----
+
+ * Fixed ``AttributeError`` when trying to download a ``setup_requires``
+   dependency when a distribution lacks a ``dependency_links`` setting.
+
+ * Made ``zip-safe`` and ``not-zip-safe`` flag files contain a single byte, so
+   as to play better with packaging tools that complain about zero-length
+   files.
+
+ * Made ``setup.py develop`` respect the ``--no-deps`` option, which it
+   previously was ignoring.
+
+ * Support ``extra_path`` option to ``setup()`` when ``install`` is run in
+   backward-compatibility mode.
+
+ * Source distributions now always include a ``setup.cfg`` file that explicitly
+   sets ``egg_info`` options such that they produce an identical version number
+   to the source distribution's version number.  (Previously, the default
+   version number could be different due to the use of ``--tag-date``, or if
+   the version was overridden on the command line that built the source
+   distribution.)
+
+-----
+0.6b4
+-----
+
+ * Fix ``register`` not obeying name/version set by ``egg_info`` command, if
+   ``egg_info`` wasn't explicitly run first on the same command line.
+
+ * Added ``--no-date`` and ``--no-svn-revision`` options to ``egg_info``
+   command, to allow suppressing tags configured in ``setup.cfg``.
+
+ * Fixed redundant warnings about missing ``README`` file(s); it should now
+   appear only if you are actually a source distribution.
+
+-----
+0.6b3
+-----
+
+ * Fix ``bdist_egg`` not including files in subdirectories of ``.egg-info``.
+
+ * Allow ``.py`` files found by the ``include_package_data`` option to be
+   automatically included.  Remove duplicate data file matches if both
+   ``include_package_data`` and ``package_data`` are used to refer to the same
+   files.
+
+-----
+0.6b1
+-----
+
+ * Strip ``module`` from the end of compiled extension modules when computing
+   the name of a ``.py`` loader/wrapper.  (Python's import machinery ignores
+   this suffix when searching for an extension module.)
+
+------
+0.6a11
+------
+
+ * Added ``test_loader`` keyword to support custom test loaders
+
+ * Added ``setuptools.file_finders`` entry point group to allow implementing
+   revision control plugins.
+
+ * Added ``--identity`` option to ``upload`` command.
+
+ * Added ``dependency_links`` to allow specifying URLs for ``--find-links``.
+
+ * Enhanced test loader to scan packages as well as modules, and call
+   ``additional_tests()`` if present to get non-unittest tests.
+
+ * Support namespace packages in conjunction with system packagers, by omitting
+   the installation of any ``__init__.py`` files for namespace packages, and
+   adding a special ``.pth`` file to create a working package in
+   ``sys.modules``.
+
+ * Made ``--single-version-externally-managed`` automatic when ``--root`` is
+   used, so that most system packagers won't require special support for
+   setuptools.
+
+ * Fixed ``setup_requires``, ``tests_require``, etc. not using ``setup.cfg`` or
+   other configuration files for their option defaults when installing, and
+   also made the install use ``--multi-version`` mode so that the project
+   directory doesn't need to support .pth files.
+
+ * ``MANIFEST.in`` is now forcibly closed when any errors occur while reading
+   it.  Previously, the file could be left open and the actual error would be
+   masked by problems trying to remove the open file on Windows systems.
+
+------
+0.6a10
+------
+
+ * Fixed the ``develop`` command ignoring ``--find-links``.
+
+-----
+0.6a9
+-----
+
+ * The ``sdist`` command no longer uses the traditional ``MANIFEST`` file to
+   create source distributions.  ``MANIFEST.in`` is still read and processed,
+   as are the standard defaults and pruning.  But the manifest is built inside
+   the project's ``.egg-info`` directory as ``SOURCES.txt``, and it is rebuilt
+   every time the ``egg_info`` command is run.
+
+ * Added the ``include_package_data`` keyword to ``setup()``, allowing you to
+   automatically include any package data listed in revision control or
+   ``MANIFEST.in``
+
+ * Added the ``exclude_package_data`` keyword to ``setup()``, allowing you to
+   trim back files included via the ``package_data`` and
+   ``include_package_data`` options.
+
+ * Fixed ``--tag-svn-revision`` not working when run from a source
+   distribution.
+
+ * Added warning for namespace packages with missing ``declare_namespace()``
+
+ * Added ``tests_require`` keyword to ``setup()``, so that e.g. packages
+   requiring ``nose`` to run unit tests can make this dependency optional
+   unless the ``test`` command is run.
+
+ * Made all commands that use ``easy_install`` respect its configuration
+   options, as this was causing some problems with ``setup.py install``.
+
+ * Added an ``unpack_directory()`` driver to ``setuptools.archive_util``, so
+   that you can process a directory tree through a processing filter as if it
+   were a zipfile or tarfile.
+
+ * Added an internal ``install_egg_info`` command to use as part of old-style
+   ``install`` operations, that installs an ``.egg-info`` directory with the
+   package.
+
+ * Added a ``--single-version-externally-managed`` option to the ``install``
+   command so that you can more easily wrap a "flat" egg in a system package.
+
+ * Enhanced ``bdist_rpm`` so that it installs single-version eggs that
+   don't rely on a ``.pth`` file.  The ``--no-egg`` option has been removed,
+   since all RPMs are now built in a more backwards-compatible format.
+
+ * Support full roundtrip translation of eggs to and from ``bdist_wininst``
+   format.  Running ``bdist_wininst`` on a setuptools-based package wraps the
+   egg in an .exe that will safely install it as an egg (i.e., with metadata
+   and entry-point wrapper scripts), and ``easy_install`` can turn the .exe
+   back into an ``.egg`` file or directory and install it as such.
+
+
+-----
+0.6a8
+-----
+
+ * Fixed some problems building extensions when Pyrex was installed, especially
+   with Python 2.4 and/or packages using SWIG.
+
+ * Made ``develop`` command accept all the same options as ``easy_install``,
+   and use the ``easy_install`` command's configuration settings as defaults.
+
+ * Made ``egg_info --tag-svn-revision`` fall back to extracting the revision
+   number from ``PKG-INFO`` in case it is being run on a source distribution of
+   a snapshot taken from a Subversion-based project.
+
+ * Automatically detect ``.dll``, ``.so`` and ``.dylib`` files that are being
+   installed as data, adding them to ``native_libs.txt`` automatically.
+
+ * Fixed some problems with fresh checkouts of projects that don't include
+   ``.egg-info/PKG-INFO`` under revision control and put the project's source
+   code directly in the project directory.  If such a package had any
+   requirements that get processed before the ``egg_info`` command can be run,
+   the setup scripts would fail with a "Missing 'Version:' header and/or
+   PKG-INFO file" error, because the egg runtime interpreted the unbuilt
+   metadata in a directory on ``sys.path`` (i.e. the current directory) as
+   being a corrupted egg.  Setuptools now monkeypatches the distribution
+   metadata cache to pretend that the egg has valid version information, until
+   it has a chance to make it actually be so (via the ``egg_info`` command).
+
+-----
+0.6a5
+-----
+
+ * Fixed missing gui/cli .exe files in distribution.  Fixed bugs in tests.
+
+-----
+0.6a3
+-----
+
+ * Added ``gui_scripts`` entry point group to allow installing GUI scripts
+   on Windows and other platforms.  (The special handling is only for Windows;
+   other platforms are treated the same as for ``console_scripts``.)
+
+-----
+0.6a2
+-----
+
+ * Added ``console_scripts`` entry point group to allow installing scripts
+   without the need to create separate script files.  On Windows, console
+   scripts get an ``.exe`` wrapper so you can just type their name.  On other
+   platforms, the scripts are written without a file extension.
+
+-----
+0.6a1
+-----
+
+ * Added support for building "old-style" RPMs that don't install an egg for
+   the target package, using a ``--no-egg`` option.
+
+ * The ``build_ext`` command now works better when using the ``--inplace``
+   option and multiple Python versions.  It now makes sure that all extensions
+   match the current Python version, even if newer copies were built for a
+   different Python version.
+
+ * The ``upload`` command no longer attaches an extra ``.zip`` when uploading
+   eggs, as PyPI now supports egg uploads without trickery.
+
+ * The ``ez_setup`` script/module now displays a warning before downloading
+   the setuptools egg, and attempts to check the downloaded egg against an
+   internal MD5 checksum table.
+
+ * Fixed the ``--tag-svn-revision`` option of ``egg_info`` not finding the
+   latest revision number; it was using the revision number of the directory
+   containing ``setup.py``, not the highest revision number in the project.
+
+ * Added ``eager_resources`` setup argument
+
+ * The ``sdist`` command now recognizes Subversion "deleted file" entries and
+   does not include them in source distributions.
+
+ * ``setuptools`` now embeds itself more thoroughly into the distutils, so that
+   other distutils extensions (e.g. py2exe, py2app) will subclass setuptools'
+   versions of things, rather than the native distutils ones.
+
+ * Added ``entry_points`` and ``setup_requires`` arguments to ``setup()``;
+   ``setup_requires`` allows you to automatically find and download packages
+   that are needed in order to *build* your project (as opposed to running it).
+
+ * ``setuptools`` now finds its commands, ``setup()`` argument validators, and
+   metadata writers using entry points, so that they can be extended by
+   third-party packages.  See `Creating distutils Extensions
+   <http://pythonhosted.org/setuptools/setuptools.html#creating-distutils-extensions>`_
+   for more details.
+
+ * The vestigial ``depends`` command has been removed.  It was never finished
+   or documented, and never would have worked without EasyInstall - which it
+   pre-dated and was never compatible with.
+
+------
+0.5a12
+------
+
+ * The zip-safety scanner now checks for modules that might be used with
+   ``python -m``, and marks them as unsafe for zipping, since Python 2.4 can't
+   handle ``-m`` on zipped modules.
+
+------
+0.5a11
+------
+
+ * Fix breakage of the "develop" command that was caused by the addition of
+   ``--always-unzip`` to the ``easy_install`` command.
+
+-----
+0.5a9
+-----
+
+ * Include ``svn:externals`` directories in source distributions as well as
+   normal subversion-controlled files and directories.
+
+ * Added ``exclude=patternlist`` option to ``setuptools.find_packages()``
+
+ * Changed --tag-svn-revision to include an "r" in front of the revision number
+   for better readability.
+
+ * Added ability to build eggs without including source files (except for any
+   scripts, of course), using the ``--exclude-source-files`` option to
+   ``bdist_egg``.
+
+ * ``setup.py install`` now automatically detects when an "unmanaged" package
+   or module is going to be on ``sys.path`` ahead of a package being installed,
+   thereby preventing the newer version from being imported.  If this occurs,
+   a warning message is output to ``sys.stderr``, but installation proceeds
+   anyway.  The warning message informs the user what files or directories
+   need deleting, and advises them they can also use EasyInstall (with the
+   ``--delete-conflicting`` option) to do it automatically.
+
+ * The ``egg_info`` command now adds a ``top_level.txt`` file to the metadata
+   directory that lists all top-level modules and packages in the distribution.
+   This is used by the ``easy_install`` command to find possibly-conflicting
+   "unmanaged" packages when installing the distribution.
+
+ * Added ``zip_safe`` and ``namespace_packages`` arguments to ``setup()``.
+   Added package analysis to determine zip-safety if the ``zip_safe`` flag
+   is not given, and advise the author regarding what code might need changing.
+
+ * Fixed the swapped ``-d`` and ``-b`` options of ``bdist_egg``.
+
+-----
+0.5a8
+-----
+
+ * The "egg_info" command now always sets the distribution metadata to "safe"
+   forms of the distribution name and version, so that distribution files will
+   be generated with parseable names (i.e., ones that don't include '-' in the
+   name or version).  Also, this means that if you use the various ``--tag``
+   options of "egg_info", any distributions generated will use the tags in the
+   version, not just egg distributions.
+
+ * Added support for defining command aliases in distutils configuration files,
+   under the "[aliases]" section.  To prevent recursion and to allow aliases to
+   call the command of the same name, a given alias can be expanded only once
+   per command-line invocation.  You can define new aliases with the "alias"
+   command, either for the local, global, or per-user configuration.
+
+ * Added "rotate" command to delete old distribution files, given a set of
+   patterns to match and the number of files to keep.  (Keeps the most
+   recently-modified distribution files matching each pattern.)
+
+ * Added "saveopts" command that saves all command-line options for the current
+   invocation to the local, global, or per-user configuration file.  Useful for
+   setting defaults without having to hand-edit a configuration file.
+
+ * Added a "setopt" command that sets a single option in a specified distutils
+   configuration file.
+
+-----
+0.5a7
+-----
+
+ * Added "upload" support for egg and source distributions, including a bug
+   fix for "upload" and a temporary workaround for lack of .egg support in
+   PyPI.
+
+-----
+0.5a6
+-----
+
+ * Beefed up the "sdist" command so that if you don't have a MANIFEST.in, it
+   will include all files under revision control (CVS or Subversion) in the
+   current directory, and it will regenerate the list every time you create a
+   source distribution, not just when you tell it to.  This should make the
+   default "do what you mean" more often than the distutils' default behavior
+   did, while still retaining the old behavior in the presence of MANIFEST.in.
+
+ * Fixed the "develop" command always updating .pth files, even if you
+   specified ``-n`` or ``--dry-run``.
+
+ * Slightly changed the format of the generated version when you use
+   ``--tag-build`` on the "egg_info" command, so that you can make tagged
+   revisions compare *lower* than the version specified in setup.py (e.g. by
+   using ``--tag-build=dev``).
+
+-----
+0.5a5
+-----
+
+ * Added ``develop`` command to ``setuptools``-based packages.  This command
+   installs an ``.egg-link`` pointing to the package's source directory, and
+   script wrappers that ``execfile()`` the source versions of the package's
+   scripts.  This lets you put your development checkout(s) on sys.path without
+   having to actually install them.  (To uninstall the link, use
+   use ``setup.py develop --uninstall``.)
+
+ * Added ``egg_info`` command to ``setuptools``-based packages.  This command
+   just creates or updates the "projectname.egg-info" directory, without
+   building an egg.  (It's used by the ``bdist_egg``, ``test``, and ``develop``
+   commands.)
+
+ * Enhanced the ``test`` command so that it doesn't install the package, but
+   instead builds any C extensions in-place, updates the ``.egg-info``
+   metadata, adds the source directory to ``sys.path``, and runs the tests
+   directly on the source.  This avoids an "unmanaged" installation of the
+   package to ``site-packages`` or elsewhere.
+
+ * Made ``easy_install`` a standard ``setuptools`` command, moving it from
+   the ``easy_install`` module to ``setuptools.command.easy_install``.  Note
+   that if you were importing or extending it, you must now change your imports
+   accordingly.  ``easy_install.py`` is still installed as a script, but not as
+   a module.
+
+-----
+0.5a4
+-----
+
+ * Setup scripts using setuptools can now list their dependencies directly in
+   the setup.py file, without having to manually create a ``depends.txt`` file.
+   The ``install_requires`` and ``extras_require`` arguments to ``setup()``
+   are used to create a dependencies file automatically.  If you are manually
+   creating ``depends.txt`` right now, please switch to using these setup
+   arguments as soon as practical, because ``depends.txt`` support will be
+   removed in the 0.6 release cycle.  For documentation on the new arguments,
+   see the ``setuptools.dist.Distribution`` class.
+
+ * Setup scripts using setuptools now always install using ``easy_install``
+   internally, for ease of uninstallation and upgrading.
+
+-----
+0.5a1
+-----
+
+ * Added support for "self-installation" bootstrapping.  Packages can now
+   include ``ez_setup.py`` in their source distribution, and add the following
+   to their ``setup.py``, in order to automatically bootstrap installation of
+   setuptools as part of their setup process::
+
+    from ez_setup import use_setuptools
+    use_setuptools()
+
+    from setuptools import setup
+    # etc...
+
+-----
+0.4a2
+-----
+
+ * Added ``ez_setup.py`` installer/bootstrap script to make initial setuptools
+   installation easier, and to allow distributions using setuptools to avoid
+   having to include setuptools in their source distribution.
+
+ * All downloads are now managed by the ``PackageIndex`` class (which is now
+   subclassable and replaceable), so that embedders can more easily override
+   download logic, give download progress reports, etc.  The class has also
+   been moved to the new ``setuptools.package_index`` module.
+
+ * The ``Installer`` class no longer handles downloading, manages a temporary
+   directory, or tracks the ``zip_ok`` option.  Downloading is now handled
+   by ``PackageIndex``, and ``Installer`` has become an ``easy_install``
+   command class based on ``setuptools.Command``.
+
+ * There is a new ``setuptools.sandbox.run_setup()`` API to invoke a setup
+   script in a directory sandbox, and a new ``setuptools.archive_util`` module
+   with an ``unpack_archive()`` API.  These were split out of EasyInstall to
+   allow reuse by other tools and applications.
+
+ * ``setuptools.Command`` now supports reinitializing commands using keyword
+   arguments to set/reset options.  Also, ``Command`` subclasses can now set
+   their ``command_consumes_arguments`` attribute to ``True`` in order to
+   receive an ``args`` option containing the rest of the command line.
+
+-----
+0.3a2
+-----
+
+ * Added new options to ``bdist_egg`` to allow tagging the egg's version number
+   with a subversion revision number, the current date, or an explicit tag
+   value.  Run ``setup.py bdist_egg --help`` to get more information.
+
+ * Misc. bug fixes
+
+-----
+0.3a1
+-----
+
+ * Initial release.

+Metadata-Version: 1.1
+Name: simplejson
+Version: 3.6.4
+Summary: Simple, fast, extensible JSON encoder/decoder for Python
+Home-page: http://github.com/simplejson/simplejson
+Author: Bob Ippolito
+Author-email: bob@redivi.com
+License: MIT License
+Description: simplejson is a simple, fast, complete, correct and extensible
+        JSON <http://json.org> encoder and decoder for Python 2.5+
+        and Python 3.3+.  It is pure Python code with no dependencies,
+        but includes an optional C extension for a serious speed boost.
+        
+        The latest documentation for simplejson can be read online here:
+        http://simplejson.readthedocs.org/
+        
+        simplejson is the externally maintained development version of the
+        json library included with Python 2.6 and Python 3.0, but maintains
+        backwards compatibility with Python 2.5.
+        
+        The encoder can be specialized to provide serialization in any kind of
+        situation, without any special support by the objects to be serialized
+        (somewhat like pickle). This is best done with the ``default`` kwarg
+        to dumps.
+        
+        The decoder can handle incoming JSON strings of any specified encoding
+        (UTF-8 by default). It can also be specialized to post-process JSON
+        objects with the ``object_hook`` or ``object_pairs_hook`` kwargs. This
+        is particularly useful for implementing protocols such as JSON-RPC
+        that have a richer type system than JSON itself.
+        
+        For those of you that have legacy systems to maintain, there is a
+        very old fork of simplejson in the `python2.2`_ branch that supports
+        Python 2.2. This is based off of a very old version of simplejson,
+        is not maintained, and should only be used as a last resort.
+

+
+:mod:`simplejson` exposes an API familiar to users of the standard library

+
+Encoding basic Python object hierarchies::
+
+    >>> import simplejson as json
+    >>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
+    '["foo", {"bar": ["baz", null, 1.0, 2]}]'

+    >>> io = StringIO()
+    >>> json.dump(['streaming API'], io)
+    >>> io.getvalue()
+    '["streaming API"]'
+
+Compact encoding::
+
+    >>> import simplejson as json
+    >>> obj = [1,2,3,{'4': 5, '6': 7}]
+    >>> json.dumps(obj, separators=(',',':'), sort_keys=True)

+    >>> io = StringIO('["streaming API"]')
+    >>> json.load(io)[0] == 'streaming API'
+    True
+

+    (1+2j)
+    >>> from decimal import Decimal
+    >>> json.loads('1.1', parse_float=Decimal) == Decimal('1.1')

+    """Serialize ``obj`` as a JSON formatted stream to ``fp`` (a
+    ``.write()``-supporting file-like object).
+
+    If *skipkeys* is true then ``dict`` keys that are not basic types
+    (``str``, ``unicode``, ``int``, ``long``, ``float``, ``bool``, ``None``)
+    will be skipped instead of raising a ``TypeError``.
+
+    If *ensure_ascii* is false, then the some chunks written to ``fp``
+    may be ``unicode`` instances, subject to normal Python ``str`` to
+    ``unicode`` coercion rules. Unless ``fp.write()`` explicitly
+    understands ``unicode`` (as in ``codecs.getwriter()``) this is likely
+    to cause an error.
+
+    If *check_circular* is false, then the circular reference check
+    for container types will be skipped and a circular reference will
+    result in an ``OverflowError`` (or worse).
+
+    If *allow_nan* is false, then it will be a ``ValueError`` to
+    serialize out of range ``float`` values (``nan``, ``inf``, ``-inf``)
+    in strict compliance of the original JSON specification, instead of using
+    the JavaScript equivalents (``NaN``, ``Infinity``, ``-Infinity``). See
+    *ignore_nan* for ECMA-262 compliant behavior.
+
+    If *indent* is a string, then JSON array elements and object members
+    will be pretty-printed with a newline followed by that string repeated
+    for each level of nesting. ``None`` (the default) selects the most compact
+    representation without any newlines. For backwards compatibility with
+    versions of simplejson earlier than 2.1.0, an integer is also accepted
+    and is converted to a string with that many spaces.
+
+    If specified, *separators* should be an
+    ``(item_separator, key_separator)`` tuple.  The default is ``(', ', ': ')``
+    if *indent* is ``None`` and ``(',', ': ')`` otherwise.  To get the most
+    compact JSON representation, you should specify ``(',', ':')`` to eliminate
+    whitespace.
+
+    *encoding* is the character encoding for str instances, default is UTF-8.
+
+    *default(obj)* is a function that should return a serializable version
+    of obj or raise ``TypeError``. The default simply raises ``TypeError``.
+
+    If *use_decimal* is true (default: ``True``) then decimal.Decimal
+    will be natively serialized to JSON with full precision.
+
+    If *namedtuple_as_object* is true (default: ``True``),
+    :class:`tuple` subclasses with ``_asdict()`` methods will be encoded
+    as JSON objects.
+
+    If *tuple_as_array* is true (default: ``True``),
+    :class:`tuple` (and subclasses) will be encoded as JSON arrays.
+
+    If *bigint_as_string* is true (default: ``False``), ints 2**53 and higher
+    or lower than -2**53 will be encoded as strings. This is to avoid the
+    rounding that happens in Javascript otherwise. Note that this is still a
+    lossy operation that will not round-trip correctly and should be used
+    sparingly.
+
+    If *int_as_string_bitcount* is a positive number (n), then int of size
+    greater than or equal to 2**n or lower than or equal to -2**n will be
+    encoded as strings.
+
+    If specified, *item_sort_key* is a callable used to sort the items in
+    each dictionary. This is useful if you want to sort items other than
+    in alphabetical order by key. This option takes precedence over
+    *sort_keys*.
+
+    If *sort_keys* is true (default: ``False``), the output of dictionaries
+    will be sorted by item.
+
+    If *for_json* is true (default: ``False``), objects with a ``for_json()``
+    method will use the return value of that method for encoding as JSON
+    instead of the object.
+
+    If *ignore_nan* is true (default: ``False``), then out of range
+    :class:`float` values (``nan``, ``inf``, ``-inf``) will be serialized as
+    ``null`` in compliance with the ECMA-262 specification. If true, this will
+    override *allow_nan*.
+
+    To use a custom ``JSONEncoder`` subclass (e.g. one that overrides the
+    ``.default()`` method to serialize additional types), specify it with
+    the ``cls`` kwarg. NOTE: You should use *default* or *for_json* instead
+    of subclassing whenever possible.

+

+    (``str``, ``unicode``, ``int``, ``long``, ``float``, ``bool``, ``None``)
+    will be skipped instead of raising a ``TypeError``.
+
+    If ``ensure_ascii`` is false, then the return value will be a
+    ``unicode`` instance subject to normal Python ``str`` to ``unicode``
+    coercion rules instead of being escaped to an ASCII ``str``.
+
+    If ``check_circular`` is false, then the circular reference check
+    for container types will be skipped and a circular reference will
+    result in an ``OverflowError`` (or worse).
+
+    If ``allow_nan`` is false, then it will be a ``ValueError`` to
+    serialize out of range ``float`` values (``nan``, ``inf``, ``-inf``) in
+    strict compliance of the JSON specification, instead of using the
+    JavaScript equivalents (``NaN``, ``Infinity``, ``-Infinity``).
+
+    If ``indent`` is a string, then JSON array elements and object members
+    will be pretty-printed with a newline followed by that string repeated
+    for each level of nesting. ``None`` (the default) selects the most compact
+    representation without any newlines. For backwards compatibility with
+    versions of simplejson earlier than 2.1.0, an integer is also accepted
+    and is converted to a string with that many spaces.
+
+    If specified, ``separators`` should be an
+    ``(item_separator, key_separator)`` tuple.  The default is ``(', ', ': ')``
+    if *indent* is ``None`` and ``(',', ': ')`` otherwise.  To get the most
+    compact JSON representation, you should specify ``(',', ':')`` to eliminate
+    whitespace.
+
+    ``encoding`` is the character encoding for str instances, default is UTF-8.
+
+    ``default(obj)`` is a function that should return a serializable version
+    of obj or raise TypeError. The default simply raises TypeError.
+
+    If *use_decimal* is true (default: ``True``) then decimal.Decimal
+    will be natively serialized to JSON with full precision.
+
+    If *namedtuple_as_object* is true (default: ``True``),
+    :class:`tuple` subclasses with ``_asdict()`` methods will be encoded
+    as JSON objects.
+
+    If *tuple_as_array* is true (default: ``True``),
+    :class:`tuple` (and subclasses) will be encoded as JSON arrays.
+
+    If *bigint_as_string* is true (not the default), ints 2**53 and higher
+    or lower than -2**53 will be encoded as strings. This is to avoid the
+    rounding that happens in Javascript otherwise.
+
+    If *int_as_string_bitcount* is a positive number (n), then int of size
+    greater than or equal to 2**n or lower than or equal to -2**n will be
+    encoded as strings.
+
+    If specified, *item_sort_key* is a callable used to sort the items in
+    each dictionary. This is useful if you want to sort items other than
+    in alphabetical order by key. This option takes precendence over
+    *sort_keys*.
+
+    If *sort_keys* is true (default: ``False``), the output of dictionaries
+    will be sorted by item.
+
+    If *for_json* is true (default: ``False``), objects with a ``for_json()``
+    method will use the return value of that method for encoding as JSON
+    instead of the object.
+
+    If *ignore_nan* is true (default: ``False``), then out of range
+    :class:`float` values (``nan``, ``inf``, ``-inf``) will be serialized as
+    ``null`` in compliance with the ECMA-262 specification. If true, this will
+    override *allow_nan*.
+
+    To use a custom ``JSONEncoder`` subclass (e.g. one that overrides the
+    ``.default()`` method to serialize additional types), specify it with
+    the ``cls`` kwarg. NOTE: You should use *default* instead of subclassing

+
+Six is a Python 2 and 3 compatibility library.  It provides utility functions
+for smoothing over the differences between the Python versions with the goal of
+writing Python code that is compatible on both Python versions.  See the
+documentation for more information on what is provided.
+
+Six supports every Python version since 2.5.  It is contained in only one Python
+file, so it can be easily copied into your project. (The copyright and license
+notice must be retained.)
+
+Online documentation is at http://pythonhosted.org/six/.
+
+Bugs can be reported to http://bitbucket.org/gutworth/six.  The code can also be
+found there.
+
+For questions about six or porting in general, email the python-porting mailing
+list: http://mail.python.org/mailman/listinfo/python-porting

+
+Drizzle is a variant of MySQL. Unlike MySQL, Drizzle's default storage engine
+is InnoDB (transactions, foreign-keys) rather than MyISAM. For more
+`Notable Differences <http://docs.drizzle.org/mysql_differences.html>`_, visit
+the `Drizzle Documentation <http://docs.drizzle.org/index.html>`_.
+
+The SQLAlchemy Drizzle dialect leans heavily on the MySQL dialect, so much of

+.. dialect:: firebird
+    :name: Firebird
+
+Firebird Dialects
+-----------------
+
+Firebird offers two distinct dialects_ (not to be confused with a
+SQLAlchemy ``Dialect``):
+
+dialect 1
+  This is the old syntax and behaviour, inherited from Interbase pre-6.0.
+
+dialect 3
+  This is the newer and supported syntax, introduced in Interbase 6.0.
+
+The SQLAlchemy Firebird dialect detects these versions and
+adjusts its representation of SQL accordingly.  However,
+support for dialect 1 is not well tested and probably has
+incompatibilities.
+
+Locking Behavior
+----------------
+
+Firebird locks tables aggressively.  For this reason, a DROP TABLE may
+hang until other transactions are released.  SQLAlchemy does its best
+to release transactions as quickly as possible.  The most common cause
+of hanging transactions is a non-fully consumed result set, i.e.::
+
+    result = engine.execute("select * from table")
+    row = result.fetchone()
+    return
+
+Where above, the ``ResultProxy`` has not been fully consumed.  The
+connection will be returned to the pool and the transactional state
+rolled back once the Python garbage collector reclaims the objects
+which hold onto the connection, which often occurs asynchronously.
+The above use case can be alleviated by calling ``first()`` on the
+``ResultProxy`` which will fetch the first row and immediately close
+all remaining cursor/connection resources.
+
+RETURNING support
+-----------------
+
+Firebird 2.0 supports returning a result set from inserts, and 2.1
+extends that to deletes and updates. This is generically exposed by
+the SQLAlchemy ``returning()`` method, such as::
+
+    # INSERT..RETURNING
+    result = table.insert().returning(table.c.col1, table.c.col2).\\
+                   values(name='foo')
+    print result.fetchall()
+
+    # UPDATE..RETURNING
+    raises = empl.update().returning(empl.c.id, empl.c.salary).\\
+                  where(empl.c.sales>100).\\
+                  values(dict(salary=empl.c.salary * 1.1))
+    print raises.fetchall()

+.. dialect:: firebird+fdb
+    :name: fdb
+    :dbapi: pyodbc
+    :connectstring: firebird+fdb://user:password@host:port/path/to/db\
+[?key=value&key=value...]
+    :url: http://pypi.python.org/pypi/fdb/
+
+    fdb is a kinterbasdb compatible DBAPI for Firebird.
+
+    .. versionadded:: 0.8 - Support for the fdb Firebird driver.
+
+    .. versionchanged:: 0.9 - The fdb dialect is now the default dialect
+       under the ``firebird://`` URL space, as ``fdb`` is now the official
+       Python driver for Firebird.
+
+Arguments
+----------
+
+The ``fdb`` dialect is based on the
+:mod:`sqlalchemy.dialects.firebird.kinterbasdb` dialect, however does not
+accept every argument that Kinterbasdb does.
+
+* ``enable_rowcount`` - True by default, setting this to False disables
+  the usage of "cursor.rowcount" with the
+  Kinterbasdb dialect, which SQLAlchemy ordinarily calls upon automatically
+  after any UPDATE or DELETE statement.   When disabled, SQLAlchemy's
+  ResultProxy will return -1 for result.rowcount.   The rationale here is
+  that Kinterbasdb requires a second round trip to the database when
+  .rowcount is called -  since SQLA's resultproxy automatically closes
+  the cursor after a non-result-returning statement, rowcount must be
+  called, if at all, before the result object is returned.   Additionally,
+  cursor.rowcount may not return correct results with older versions
+  of Firebird, and setting this flag to False will also cause the
+  SQLAlchemy ORM to ignore its usage. The behavior can also be controlled on a
+  per-execution basis using the ``enable_rowcount`` option with
+  :meth:`.Connection.execution_options`::
+
+      conn = engine.connect().execution_options(enable_rowcount=True)
+      r = conn.execute(stmt)
+      print r.rowcount
+
+* ``retaining`` - False by default.   Setting this to True will pass the
+  ``retaining=True`` keyword argument to the ``.commit()`` and ``.rollback()``
+  methods of the DBAPI connection, which can improve performance in some
+  situations, but apparently with significant caveats.
+  Please read the fdb and/or kinterbasdb DBAPI documentation in order to
+  understand the implications of this flag.
+
+  .. versionadded:: 0.8.2 - ``retaining`` keyword argument specifying
+     transaction retaining behavior - in 0.8 it defaults to ``True``
+     for backwards compatibility.
+
+  .. versionchanged:: 0.9.0 - the ``retaining`` flag defaults to ``False``.
+     In 0.8 it defaulted to ``True``.
+
+  .. seealso::
+
+    http://pythonhosted.org/fdb/usage-guide.html#retaining-transactions

+
+
+Auto Increment Behavior
+-----------------------
+
+SQL Server provides so-called "auto incrementing" behavior using the
+``IDENTITY`` construct, which can be placed on an integer primary key.
+SQLAlchemy considers ``IDENTITY`` within its default "autoincrement" behavior,
+described at :paramref:`.Column.autoincrement`; this means
+that by default, the first integer primary key column in a :class:`.Table`
+will be considered to be the identity column and will generate DDL as such::
+
+    from sqlalchemy import Table, MetaData, Column, Integer
+
+    m = MetaData()
+    t = Table('t', m,
+            Column('id', Integer, primary_key=True),
+            Column('x', Integer))
+    m.create_all(engine)
+
+The above example will generate DDL as:
+
+.. sourcecode:: sql
+
+    CREATE TABLE t (
+        id INTEGER NOT NULL IDENTITY(1,1),
+        x INTEGER NULL,
+        PRIMARY KEY (id)
+    )
+
+For the case where this default generation of ``IDENTITY`` is not desired,
+specify ``autoincrement=False`` on all integer primary key columns::
+
+    m = MetaData()
+    t = Table('t', m,
+            Column('id', Integer, primary_key=True, autoincrement=False),
+            Column('x', Integer))
+    m.create_all(engine)
+
+.. note::
+
+    An INSERT statement which refers to an explicit value for such
+    a column is prohibited by SQL Server, however SQLAlchemy will detect this
+    and modify the ``IDENTITY_INSERT`` flag accordingly at statement execution
+    time.  As this is not a high performing process, care should be taken to
+    set the ``autoincrement`` flag appropriately for columns that will not
+    actually require IDENTITY behavior.
+
+Controlling "Start" and "Increment"
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Specific control over the parameters of the ``IDENTITY`` value is supported
+using the :class:`.schema.Sequence` object.  While this object normally
+represents an explicit "sequence" for supporting backends, on SQL Server it is
+re-purposed to specify behavior regarding the identity column, including
+support of the "start" and "increment" values::
+
+    from sqlalchemy import Table, Integer, Sequence, Column
+
+    Table('test', metadata,
+           Column('id', Integer,
+                  Sequence('blah', start=100, increment=10),
+                  primary_key=True),
+           Column('name', String(20))
+         ).create(some_engine)
+
+would yield:
+
+.. sourcecode:: sql
+
+   CREATE TABLE test (
+     id INTEGER NOT NULL IDENTITY(100,10) PRIMARY KEY,
+     name VARCHAR(20) NULL,
+     )
+
+Note that the ``start`` and ``increment`` values for sequences are
+optional and will default to 1,1.
+
+INSERT behavior
+^^^^^^^^^^^^^^^^
+
+Handling of the ``IDENTITY`` column at INSERT time involves two key
+techniques. The most common is being able to fetch the "last inserted value"
+for a given ``IDENTITY`` column, a process which SQLAlchemy performs
+implicitly in many cases, most importantly within the ORM.
+
+The process for fetching this value has several variants:
+
+* In the vast majority of cases, RETURNING is used in conjunction with INSERT
+  statements on SQL Server in order to get newly generated primary key values:
+
+  .. sourcecode:: sql
+
+    INSERT INTO t (x) OUTPUT inserted.id VALUES (?)
+
+* When RETURNING is not available or has been disabled via
+  ``implicit_returning=False``, either the ``scope_identity()`` function or
+  the ``@@identity`` variable is used; behavior varies by backend:
+
+  * when using PyODBC, the phrase ``; select scope_identity()`` will be
+    appended to the end of the INSERT statement; a second result set will be
+    fetched in order to receive the value.  Given a table as::
+
+        t = Table('t', m, Column('id', Integer, primary_key=True),
+                Column('x', Integer),
+                implicit_returning=False)
+
+    an INSERT will look like:
+
+    .. sourcecode:: sql
+
+        INSERT INTO t (x) VALUES (?); select scope_identity()
+
+  * Other dialects such as pymssql will call upon
+    ``SELECT scope_identity() AS lastrowid`` subsequent to an INSERT
+    statement. If the flag ``use_scope_identity=False`` is passed to
+    :func:`.create_engine`, the statement ``SELECT @@identity AS lastrowid``
+    is used instead.
+
+A table that contains an ``IDENTITY`` column will prohibit an INSERT statement
+that refers to the identity column explicitly.  The SQLAlchemy dialect will
+detect when an INSERT construct, created using a core :func:`.insert`
+construct (not a plain string SQL), refers to the identity column, and
+in this case will emit ``SET IDENTITY_INSERT ON`` prior to the insert
+statement proceeding, and ``SET IDENTITY_INSERT OFF`` subsequent to the
+execution.  Given this example::
+
+    m = MetaData()
+    t = Table('t', m, Column('id', Integer, primary_key=True),
+                    Column('x', Integer))
+    m.create_all(engine)
+
+    engine.execute(t.insert(), {'id': 1, 'x':1}, {'id':2, 'x':2})
+
+The above column will be created with IDENTITY, however the INSERT statement
+we emit is specifying explicit values.  In the echo output we can see
+how SQLAlchemy handles this:
+
+.. sourcecode:: sql
+
+    CREATE TABLE t (
+        id INTEGER NOT NULL IDENTITY(1,1),
+        x INTEGER NULL,
+        PRIMARY KEY (id)
+    )
+
+    COMMIT
+    SET IDENTITY_INSERT t ON
+    INSERT INTO t (id, x) VALUES (?, ?)
+    ((1, 1), (2, 2))
+    SET IDENTITY_INSERT t OFF
+    COMMIT
+
+
+
+This
+is an auxilliary use case suitable for testing and bulk insert scenarios.
+
+
+Collation Support
+-----------------
+
+Character collations are supported by the base string types,
+specified by the string argument "collation"::
+
+    from sqlalchemy import VARCHAR
+    Column('login', VARCHAR(32, collation='Latin1_General_CI_AS'))
+
+When such a column is associated with a :class:`.Table`, the
+CREATE TABLE statement for this column will yield::
+
+    login VARCHAR(32) COLLATE Latin1_General_CI_AS NULL
+
+.. versionadded:: 0.8 Character collations are now part of the base string
+   types.
+
+LIMIT/OFFSET Support
+--------------------
+
+MSSQL has no support for the LIMIT or OFFSET keysowrds. LIMIT is
+supported directly through the ``TOP`` Transact SQL keyword::
+
+    select.limit
+
+will yield::
+
+    SELECT TOP n
+
+If using SQL Server 2005 or above, LIMIT with OFFSET
+support is available through the ``ROW_NUMBER OVER`` construct.
+For versions below 2005, LIMIT with OFFSET usage will fail.
+
+Nullability
+-----------
+MSSQL has support for three levels of column nullability. The default
+nullability allows nulls and is explicit in the CREATE TABLE
+construct::
+
+    name VARCHAR(20) NULL
+
+If ``nullable=None`` is specified then no specification is made. In
+other words the database's configured default is used. This will
+render::
+
+    name VARCHAR(20)
+
+If ``nullable`` is ``True`` or ``False`` then the column will be
+``NULL` or ``NOT NULL`` respectively.
+
+Date / Time Handling
+--------------------
+DATE and TIME are supported.   Bind parameters are converted
+to datetime.datetime() objects as required by most MSSQL drivers,
+and results are processed from strings if needed.
+The DATE and TIME types are not available for MSSQL 2005 and
+previous - if a server version below 2008 is detected, DDL
+for these types will be issued as DATETIME.
+
+.. _mssql_indexes:
+
+Clustered Index Support
+-----------------------
+
+The MSSQL dialect supports clustered indexes (and primary keys) via the
+``mssql_clustered`` option.  This option is available to :class:`.Index`,
+:class:`.UniqueConstraint`. and :class:`.PrimaryKeyConstraint`.
+
+To generate a clustered index::
+
+    Index("my_index", table.c.x, mssql_clustered=True)
+
+which renders the index as ``CREATE CLUSTERED INDEX my_index ON table (x)``.
+
+.. versionadded:: 0.8
+
+To generate a clustered primary key use::
+
+    Table('my_table', metadata,
+          Column('x', ...),
+          Column('y', ...),
+          PrimaryKeyConstraint("x", "y", mssql_clustered=True))
+
+which will render the table, for example, as::
+
+  CREATE TABLE my_table (x INTEGER NOT NULL, y INTEGER NOT NULL,
+                         PRIMARY KEY CLUSTERED (x, y))
+
+Similarly, we can generate a clustered unique constraint using::
+
+    Table('my_table', metadata,
+          Column('x', ...),
+          Column('y', ...),
+          PrimaryKeyConstraint("x"),
+          UniqueConstraint("y", mssql_clustered=True),
+          )
+
+  .. versionadded:: 0.9.2
+
+MSSQL-Specific Index Options
+-----------------------------
+
+In addition to clustering, the MSSQL dialect supports other special options
+for :class:`.Index`.
+
+INCLUDE
+^^^^^^^
+
+The ``mssql_include`` option renders INCLUDE(colname) for the given string
+names::
+
+    Index("my_index", table.c.x, mssql_include=['y'])
+
+would render the index as ``CREATE INDEX my_index ON table (x) INCLUDE (y)``
+
+.. versionadded:: 0.8
+
+Index ordering
+^^^^^^^^^^^^^^
+
+Index ordering is available via functional expressions, such as::
+
+    Index("my_index", table.c.x.desc())
+
+would render the index as ``CREATE INDEX my_index ON table (x DESC)``
+
+.. versionadded:: 0.8
+
+.. seealso::
+
+    :ref:`schema_indexes_functional`
+
+Compatibility Levels
+--------------------
+MSSQL supports the notion of setting compatibility levels at the
+database level. This allows, for instance, to run a database that
+is compatible with SQL2000 while running on a SQL2005 database
+server. ``server_version_info`` will always return the database
+server version information (in this case SQL2005) and not the
+compatibility level information. Because of this, if running under
+a backwards compatibility mode SQAlchemy may attempt to use T-SQL
+statements that are unable to be parsed by the database server.
+
+Triggers
+--------
+
+SQLAlchemy by default uses OUTPUT INSERTED to get at newly
+generated primary key values via IDENTITY columns or other
+server side defaults.   MS-SQL does not
+allow the usage of OUTPUT INSERTED on tables that have triggers.
+To disable the usage of OUTPUT INSERTED on a per-table basis,
+specify ``implicit_returning=False`` for each :class:`.Table`
+which has triggers::
+
+    Table('mytable', metadata,
+        Column('id', Integer, primary_key=True),
+        # ...,
+        implicit_returning=False
+    )
+
+Declarative form::
+
+    class MyClass(Base):
+        # ...
+        __table_args__ = {'implicit_returning':False}
+
+
+This option can also be specified engine-wide using the
+``implicit_returning=False`` argument on :func:`.create_engine`.
+
+Enabling Snapshot Isolation
+---------------------------
+
+Not necessarily specific to SQLAlchemy, SQL Server has a default transaction
+isolation mode that locks entire tables, and causes even mildly concurrent
+applications to have long held locks and frequent deadlocks.
+Enabling snapshot isolation for the database as a whole is recommended
+for modern levels of concurrency support.  This is accomplished via the
+following ALTER DATABASE commands executed at the SQL prompt::
+
+    ALTER DATABASE MyDatabase SET ALLOW_SNAPSHOT_ISOLATION ON
+
+    ALTER DATABASE MyDatabase SET READ_COMMITTED_SNAPSHOT ON
+
+Background on SQL Server snapshot isolation is available at
+http://msdn.microsoft.com/en-us/library/ms175095.aspx.
+
+Known Issues

+
+Execution Modes
+---------------
+
+mxODBC features two styles of statement execution, using the
+``cursor.execute()`` and ``cursor.executedirect()`` methods (the second being
+an extension to the DBAPI specification). The former makes use of a particular
+API call specific to the SQL Server Native Client ODBC driver known
+SQLDescribeParam, while the latter does not.
+
+mxODBC apparently only makes repeated use of a single prepared statement
+when SQLDescribeParam is used. The advantage to prepared statement reuse is
+one of performance. The disadvantage is that SQLDescribeParam has a limited
+set of scenarios in which bind parameters are understood, including that they
+cannot be placed within the argument lists of function calls, anywhere outside
+the FROM, or even within subqueries within the FROM clause - making the usage
+of bind parameters within SELECT statements impossible for all but the most
+simplistic statements.
+
+For this reason, the mxODBC dialect uses the "native" mode by default only for
+INSERT, UPDATE, and DELETE statements, and uses the escaped string mode for
+all other statements.
+
+This behavior can be controlled via
+:meth:`~sqlalchemy.sql.expression.Executable.execution_options` using the
+``native_odbc_execute`` flag with a value of ``True`` or ``False``, where a
+value of ``True`` will unconditionally use native bind parameters and a value
+of ``False`` will unconditionally use string-escaped parameters.

+Additional Connection Examples
+-------------------------------
+
+Examples of pyodbc connection string URLs:
+
+* ``mssql+pyodbc://mydsn`` - connects using the specified DSN named ``mydsn``.
+  The connection string that is created will appear like::
+
+    dsn=mydsn;Trusted_Connection=Yes
+
+* ``mssql+pyodbc://user:pass@mydsn`` - connects using the DSN named
+  ``mydsn`` passing in the ``UID`` and ``PWD`` information. The
+  connection string that is created will appear like::
+
+    dsn=mydsn;UID=user;PWD=pass
+
+* ``mssql+pyodbc://user:pass@mydsn/?LANGUAGE=us_english`` - connects
+  using the DSN named ``mydsn`` passing in the ``UID`` and ``PWD``
+  information, plus the additional connection configuration option
+  ``LANGUAGE``. The connection string that is created will appear
+  like::
+
+    dsn=mydsn;UID=user;PWD=pass;LANGUAGE=us_english
+
+* ``mssql+pyodbc://user:pass@host/db`` - connects using a connection
+  that would appear like::
+
+    DRIVER={SQL Server};Server=host;Database=db;UID=user;PWD=pass
+
+* ``mssql+pyodbc://user:pass@host:123/db`` - connects using a connection
+  string which includes the port
+  information using the comma syntax. This will create the following
+  connection string::
+
+    DRIVER={SQL Server};Server=host,123;Database=db;UID=user;PWD=pass
+
+* ``mssql+pyodbc://user:pass@host/db?port=123`` - connects using a connection
+  string that includes the port
+  information as a separate ``port`` keyword. This will create the
+  following connection string::
+
+    DRIVER={SQL Server};Server=host;Database=db;UID=user;PWD=pass;port=123
+
+* ``mssql+pyodbc://user:pass@host/db?driver=MyDriver`` - connects using a
+  connection string that includes a custom ODBC driver name.  This will create
+  the following connection string::
+
+    DRIVER={MyDriver};Server=host;Database=db;UID=user;PWD=pass
+
+If you require a connection string that is outside the options
+presented above, use the ``odbc_connect`` keyword to pass in a
+urlencoded connection string. What gets passed in will be urldecoded
+and passed directly.
+
+For example::
+
+    mssql+pyodbc:///?odbc_connect=dsn%3Dmydsn%3BDatabase%3Ddb
+
+would create the following connection string::
+
+    dsn=mydsn;Database=db
+
+Encoding your connection string can be easily accomplished through
+the python shell. For example::
+
+    >>> import urllib
+    >>> urllib.quote_plus('dsn=mydsn;Database=db')
+    'dsn%3Dmydsn%3BDatabase%3Ddb'
+
+Unicode Binds
+-------------
+
+The current state of PyODBC on a unix backend with FreeTDS and/or
+EasySoft is poor regarding unicode; different OS platforms and versions of
+UnixODBC versus IODBC versus FreeTDS/EasySoft versus PyODBC itself
+dramatically alter how strings are received.  The PyODBC dialect attempts to
+use all the information it knows to determine whether or not a Python unicode
+literal can be passed directly to the PyODBC driver or not; while SQLAlchemy
+can encode these to bytestrings first, some users have reported that PyODBC
+mis-handles bytestrings for certain encodings and requires a Python unicode
+object, while the author has observed widespread cases where a Python unicode
+is completely misinterpreted by PyODBC, particularly when dealing with
+the information schema tables used in table reflection, and the value
+must first be encoded to a bytestring.
+
+It is for this reason that whether or not unicode literals for bound
+parameters be sent to PyODBC can be controlled using the
+``supports_unicode_binds`` parameter to ``create_engine()``.  When
+left at its default of ``None``, the PyODBC dialect will use its
+best guess as to whether or not the driver deals with unicode literals
+well.  When ``False``, unicode literals will be encoded first, and when
+``True`` unicode literals will be passed straight through.  This is an interim
+flag that hopefully should not be needed when the unicode situation stabilizes
+for unix + PyODBC.

+.. dialect:: mysql
+    :name: MySQL
+
+Supported Versions and Features
+-------------------------------
+
+SQLAlchemy supports MySQL starting with version 4.1 through modern releases.
+However, no heroic measures are taken to work around major missing
+SQL features - if your server version does not support sub-selects, for
+example, they won't work in SQLAlchemy either.
+
+See the official MySQL documentation for detailed information about features
+supported in any given server release.
+
+.. _mysql_connection_timeouts:
+
+Connection Timeouts
+-------------------
+
+MySQL features an automatic connection close behavior, for connections that
+have been idle for eight hours or more.   To circumvent having this issue, use
+the ``pool_recycle`` option which controls the maximum age of any connection::
+
+    engine = create_engine('mysql+mysqldb://...', pool_recycle=3600)
+
+.. _mysql_storage_engines:
+
+CREATE TABLE arguments including Storage Engines
+------------------------------------------------
+
+MySQL's CREATE TABLE syntax includes a wide array of special options,
+including ``ENGINE``, ``CHARSET``, ``MAX_ROWS``, ``ROW_FORMAT``,
+``INSERT_METHOD``, and many more.
+To accommodate the rendering of these arguments, specify the form
+``mysql_argument_name="value"``.  For example, to specify a table with
+``ENGINE`` of ``InnoDB``, ``CHARSET`` of ``utf8``, and ``KEY_BLOCK_SIZE``
+of ``1024``::
+
+  Table('mytable', metadata,
+        Column('data', String(32)),
+        mysql_engine='InnoDB',
+        mysql_charset='utf8',
+        mysql_key_block_size="1024"
+       )
+
+The MySQL dialect will normally transfer any keyword specified as
+``mysql_keyword_name`` to be rendered as ``KEYWORD_NAME`` in the
+``CREATE TABLE`` statement.  A handful of these names will render with a space
+instead of an underscore; to support this, the MySQL dialect has awareness of
+these particular names, which include ``DATA DIRECTORY``
+(e.g. ``mysql_data_directory``), ``CHARACTER SET`` (e.g.
+``mysql_character_set``) and ``INDEX DIRECTORY`` (e.g.
+``mysql_index_directory``).
+
+The most common argument is ``mysql_engine``, which refers to the storage
+engine for the table.  Historically, MySQL server installations would default
+to ``MyISAM`` for this value, although newer versions may be defaulting
+to ``InnoDB``.  The ``InnoDB`` engine is typically preferred for its support
+of transactions and foreign keys.
+
+A :class:`.Table` that is created in a MySQL database with a storage engine
+of ``MyISAM`` will be essentially non-transactional, meaning any
+INSERT/UPDATE/DELETE statement referring to this table will be invoked as
+autocommit.   It also will have no support for foreign key constraints; while
+the ``CREATE TABLE`` statement accepts foreign key options, when using the
+``MyISAM`` storage engine these arguments are discarded.  Reflecting such a
+table will also produce no foreign key constraint information.
+
+For fully atomic transactions as well as support for foreign key
+constraints, all participating ``CREATE TABLE`` statements must specify a
+transactional engine, which in the vast majority of cases is ``InnoDB``.
+
+.. seealso::
+
+    `The InnoDB Storage Engine
+    <http://dev.mysql.com/doc/refman/5.0/en/innodb-storage-engine.html>`_ -
+    on the MySQL website.
+
+Case Sensitivity and Table Reflection
+-------------------------------------
+
+MySQL has inconsistent support for case-sensitive identifier
+names, basing support on specific details of the underlying
+operating system. However, it has been observed that no matter
+what case sensitivity behavior is present, the names of tables in
+foreign key declarations are *always* received from the database
+as all-lower case, making it impossible to accurately reflect a
+schema where inter-related tables use mixed-case identifier names.
+
+Therefore it is strongly advised that table names be declared as
+all lower case both within SQLAlchemy as well as on the MySQL
+database itself, especially if database reflection features are
+to be used.
+
+Transaction Isolation Level
+---------------------------
+
+:func:`.create_engine` accepts an ``isolation_level``
+parameter which results in the command ``SET SESSION
+TRANSACTION ISOLATION LEVEL <level>`` being invoked for
+every new connection. Valid values for this parameter are
+``READ COMMITTED``, ``READ UNCOMMITTED``,
+``REPEATABLE READ``, and ``SERIALIZABLE``::
+
+    engine = create_engine(
+                    "mysql://scott:tiger@localhost/test",
+                    isolation_level="READ UNCOMMITTED"
+                )
+
+.. versionadded:: 0.7.6
+
+AUTO_INCREMENT Behavior
+-----------------------
+
+When creating tables, SQLAlchemy will automatically set ``AUTO_INCREMENT`` on
+the first :class:`.Integer` primary key column which is not marked as a
+foreign key::
+
+  >>> t = Table('mytable', metadata,
+  ...   Column('mytable_id', Integer, primary_key=True)
+  ... )
+  >>> t.create()
+  CREATE TABLE mytable (
+          id INTEGER NOT NULL AUTO_INCREMENT,
+          PRIMARY KEY (id)
+  )
+
+You can disable this behavior by passing ``False`` to the
+:paramref:`~.Column.autoincrement` argument of :class:`.Column`.  This flag
+can also be used to enable auto-increment on a secondary column in a
+multi-column key for some storage engines::
+
+  Table('mytable', metadata,
+        Column('gid', Integer, primary_key=True, autoincrement=False),
+        Column('id', Integer, primary_key=True)
+       )
+
+Ansi Quoting Style
+------------------
+
+MySQL features two varieties of identifier "quoting style", one using
+backticks and the other using quotes, e.g. ```some_identifier```  vs.
+``"some_identifier"``.   All MySQL dialects detect which version
+is in use by checking the value of ``sql_mode`` when a connection is first
+established with a particular :class:`.Engine`.  This quoting style comes
+into play when rendering table and column names as well as when reflecting
+existing database structures.  The detection is entirely automatic and
+no special configuration is needed to use either quoting style.
+
+.. versionchanged:: 0.6 detection of ANSI quoting style is entirely automatic,
+   there's no longer any end-user ``create_engine()`` options in this regard.
+
+MySQL SQL Extensions
+--------------------
+
+Many of the MySQL SQL extensions are handled through SQLAlchemy's generic
+function and operator support::
+
+  table.select(table.c.password==func.md5('plaintext'))
+  table.select(table.c.username.op('regexp')('^[a-d]'))
+
+And of course any valid MySQL statement can be executed as a string as well.
+
+Some limited direct support for MySQL extensions to SQL is currently
+available.
+
+* SELECT pragma::
+
+    select(..., prefixes=['HIGH_PRIORITY', 'SQL_SMALL_RESULT'])
+
+* UPDATE with LIMIT::
+
+    update(..., mysql_limit=10)
+
+rowcount Support
+----------------
+
+SQLAlchemy standardizes the DBAPI ``cursor.rowcount`` attribute to be the
+usual definition of "number of rows matched by an UPDATE or DELETE" statement.
+This is in contradiction to the default setting on most MySQL DBAPI drivers,
+which is "number of rows actually modified/deleted".  For this reason, the
+SQLAlchemy MySQL dialects always set the ``constants.CLIENT.FOUND_ROWS`` flag,
+or whatever is equivalent for the DBAPI in use, on connect, unless the flag
+value is overridden using DBAPI-specific options
+(such as ``client_flag`` for the MySQL-Python driver, ``found_rows`` for the
+OurSQL driver).
+
+See also:
+
+:attr:`.ResultProxy.rowcount`
+
+
+CAST Support
+------------
+
+MySQL documents the CAST operator as available in version 4.0.2.  When using
+the SQLAlchemy :func:`.cast` function, SQLAlchemy
+will not render the CAST token on MySQL before this version, based on server
+version detection, instead rendering the internal expression directly.
+
+CAST may still not be desirable on an early MySQL version post-4.0.2, as it
+didn't add all datatype support until 4.1.1.   If your application falls into
+this narrow area, the behavior of CAST can be controlled using the
+:ref:`sqlalchemy.ext.compiler_toplevel` system, as per the recipe below::
+
+    from sqlalchemy.sql.expression import Cast
+    from sqlalchemy.ext.compiler import compiles
+
+    @compiles(Cast, 'mysql')
+    def _check_mysql_version(element, compiler, **kw):
+        if compiler.dialect.server_version_info < (4, 1, 0):
+            return compiler.process(element.clause, **kw)
+        else:
+            return compiler.visit_cast(element, **kw)
+
+The above function, which only needs to be declared once
+within an application, overrides the compilation of the
+:func:`.cast` construct to check for version 4.1.0 before
+fully rendering CAST; else the internal element of the
+construct is rendered directly.
+
+
+.. _mysql_indexes:
+
+MySQL Specific Index Options
+----------------------------
+
+MySQL-specific extensions to the :class:`.Index` construct are available.
+
+Index Length
+~~~~~~~~~~~~~
+
+MySQL provides an option to create index entries with a certain length, where
+"length" refers to the number of characters or bytes in each value which will
+become part of the index. SQLAlchemy provides this feature via the
+``mysql_length`` parameter::
+
+    Index('my_index', my_table.c.data, mysql_length=10)
+
+    Index('a_b_idx', my_table.c.a, my_table.c.b, mysql_length={'a': 4,
+                                                               'b': 9})
+
+Prefix lengths are given in characters for nonbinary string types and in bytes
+for binary string types. The value passed to the keyword argument *must* be
+either an integer (and, thus, specify the same prefix length value for all
+columns of the index) or a dict in which keys are column names and values are
+prefix length values for corresponding columns. MySQL only allows a length for
+a column of an index if it is for a CHAR, VARCHAR, TEXT, BINARY, VARBINARY and
+BLOB.
+
+.. versionadded:: 0.8.2 ``mysql_length`` may now be specified as a dictionary
+   for use with composite indexes.
+
+Index Types
+~~~~~~~~~~~~~
+
+Some MySQL storage engines permit you to specify an index type when creating
+an index or primary key constraint. SQLAlchemy provides this feature via the
+``mysql_using`` parameter on :class:`.Index`::
+
+    Index('my_index', my_table.c.data, mysql_using='hash')
+
+As well as the ``mysql_using`` parameter on :class:`.PrimaryKeyConstraint`::
+
+    PrimaryKeyConstraint("data", mysql_using='hash')
+
+The value passed to the keyword argument will be simply passed through to the
+underlying CREATE INDEX or PRIMARY KEY clause, so it *must* be a valid index
+type for your MySQL storage engine.

+
+MySQL Foreign Keys
+------------------
+
+MySQL's behavior regarding foreign keys has some important caveats.
+
+Foreign Key Arguments to Avoid
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+MySQL does not support the foreign key arguments "DEFERRABLE", "INITIALLY",
+or "MATCH".  Using the ``deferrable`` or ``initially`` keyword argument with
+:class:`.ForeignKeyConstraint` or :class:`.ForeignKey` will have the effect of
+these keywords being rendered in a DDL expression, which will then raise an
+error on MySQL.  In order to use these keywords on a foreign key while having
+them ignored on a MySQL backend, use a custom compile rule::
+
+    from sqlalchemy.ext.compiler import compiles
+    from sqlalchemy.schema import ForeignKeyConstraint
+
+    @compiles(ForeignKeyConstraint, "mysql")
+    def process(element, compiler, **kw):
+        element.deferrable = element.initially = None
+        return compiler.visit_foreign_key_constraint(element, **kw)
+
+.. versionchanged:: 0.9.0 - the MySQL backend no longer silently ignores
+   the ``deferrable`` or ``initially`` keyword arguments of
+   :class:`.ForeignKeyConstraint` and :class:`.ForeignKey`.
+
+The "MATCH" keyword is in fact more insidious, and is explicitly disallowed
+by SQLAlchemy in conjunction with the MySQL backend.  This argument is
+silently ignored by MySQL, but in addition has the effect of ON UPDATE and ON
+DELETE options also being ignored by the backend.   Therefore MATCH should
+never be used with the MySQL backend; as is the case with DEFERRABLE and
+INITIALLY, custom compilation rules can be used to correct a MySQL
+ForeignKeyConstraint at DDL definition time.
+
+.. versionadded:: 0.9.0 - the MySQL backend will raise a
+   :class:`.CompileError` when the ``match`` keyword is used with
+   :class:`.ForeignKeyConstraint` or :class:`.ForeignKey`.
+
+Reflection of Foreign Key Constraints
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Not all MySQL storage engines support foreign keys.  When using the
+very common ``MyISAM`` MySQL storage engine, the information loaded by table
+reflection will not include foreign keys.  For these tables, you may supply a
+:class:`~sqlalchemy.ForeignKeyConstraint` at reflection time::
+
+  Table('mytable', metadata,
+        ForeignKeyConstraint(['other_id'], ['othertable.other_id']),
+        autoload=True
+       )
+
+.. seealso::

+
+Unicode
+-------
+
+MySQLdb requires a "charset" parameter to be passed in order for it
+to handle non-ASCII characters correctly.   When this parameter is passed,
+MySQLdb will also implicitly set the "use_unicode" flag to true, which means
+that it will return Python unicode objects instead of bytestrings.
+However, SQLAlchemy's decode process, when C extensions are enabled,
+is orders of magnitude faster than that of MySQLdb as it does not call into
+Python functions to do so.  Therefore, the **recommended URL to use for
+unicode** will include both charset and use_unicode=0::
+
+    create_engine("mysql+mysqldb://user:pass@host/dbname?charset=utf8&use_unicode=0")
+
+As of this writing, MySQLdb only runs on Python 2.   It is not known how
+MySQLdb behaves on Python 3 as far as unicode decoding.
+
+
+Known Issues
+-------------
+
+MySQL-python version 1.2.2 has a serious memory leak related
+to unicode conversion, a feature which is disabled via ``use_unicode=0``.
+It is strongly advised to use the latest version of MySQL-Python.

+
+* ``use_ansi`` - Use ANSI JOIN constructs (see the section on Oracle 8).
+  Defaults to ``True``.  If ``False``, Oracle-8 compatible constructs are used
+  for joins.
+
+* ``optimize_limits`` - defaults to ``False``. see the section on
+  LIMIT/OFFSET.
+
+* ``use_binds_for_limits`` - defaults to ``True``.  see the section on
+  LIMIT/OFFSET.
+
+Auto Increment Behavior
+-----------------------
+
+SQLAlchemy Table objects which include integer primary keys are usually
+assumed to have "autoincrementing" behavior, meaning they can generate their
+own primary key values upon INSERT.  Since Oracle has no "autoincrement"
+feature, SQLAlchemy relies upon sequences to produce these values.   With the
+Oracle dialect, *a sequence must always be explicitly specified to enable
+autoincrement*.  This is divergent with the majority of documentation
+examples which assume the usage of an autoincrement-capable database.   To
+specify sequences, use the sqlalchemy.schema.Sequence object which is passed
+to a Column construct::
+
+  t = Table('mytable', metadata,
+        Column('id', Integer, Sequence('id_seq'), primary_key=True),
+        Column(...), ...
+  )
+
+This step is also required when using table reflection, i.e. autoload=True::
+
+  t = Table('mytable', metadata,
+        Column('id', Integer, Sequence('id_seq'), primary_key=True),
+        autoload=True
+  )
+
+Identifier Casing
+-----------------
+
+In Oracle, the data dictionary represents all case insensitive identifier
+names using UPPERCASE text.   SQLAlchemy on the other hand considers an
+all-lower case identifier name to be case insensitive.   The Oracle dialect
+converts all case insensitive identifiers to and from those two formats during
+schema level communication, such as reflection of tables and indexes.   Using
+an UPPERCASE name on the SQLAlchemy side indicates a case sensitive
+identifier, and SQLAlchemy will quote the name - this will cause mismatches
+against data dictionary data received from Oracle, so unless identifier names
+have been truly created as case sensitive (i.e. using quoted names), all
+lowercase names should be used on the SQLAlchemy side.
+
+
+LIMIT/OFFSET Support
+--------------------
+
+Oracle has no support for the LIMIT or OFFSET keywords.  SQLAlchemy uses
+a wrapped subquery approach in conjunction with ROWNUM.  The exact methodology
+is taken from
+http://www.oracle.com/technology/oramag/oracle/06-sep/o56asktom.html .
+
+There are two options which affect its behavior:
+
+* the "FIRST ROWS()" optimization keyword is not used by default.  To enable
+  the usage of this optimization directive, specify ``optimize_limits=True``
+  to :func:`.create_engine`.
+* the values passed for the limit/offset are sent as bound parameters.   Some
+  users have observed that Oracle produces a poor query plan when the values
+  are sent as binds and not rendered literally.   To render the limit/offset
+  values literally within the SQL statement, specify
+  ``use_binds_for_limits=False`` to :func:`.create_engine`.
+
+Some users have reported better performance when the entirely different
+approach of a window query is used, i.e. ROW_NUMBER() OVER (ORDER BY), to
+provide LIMIT/OFFSET (note that the majority of users don't observe this).
+To suit this case the method used for LIMIT/OFFSET can be replaced entirely.
+See the recipe at
+http://www.sqlalchemy.org/trac/wiki/UsageRecipes/WindowFunctionsByDefault
+which installs a select compiler that overrides the generation of limit/offset
+with a window function.
+
+.. _oracle_returning:
+
+RETURNING Support
+-----------------
+
+The Oracle database supports a limited form of RETURNING, in order to retrieve
+result sets of matched rows from INSERT, UPDATE and DELETE statements.
+Oracle's RETURNING..INTO syntax only supports one row being returned, as it
+relies upon OUT parameters in order to function.  In addition, supported
+DBAPIs have further limitations (see :ref:`cx_oracle_returning`).
+
+SQLAlchemy's "implicit returning" feature, which employs RETURNING within an
+INSERT and sometimes an UPDATE statement in order to fetch newly generated
+primary key values and other SQL defaults and expressions, is normally enabled
+on the Oracle backend.  By default, "implicit returning" typically only
+fetches the value of a single ``nextval(some_seq)`` expression embedded into
+an INSERT in order to increment a sequence within an INSERT statement and get
+the value back at the same time. To disable this feature across the board,
+specify ``implicit_returning=False`` to :func:`.create_engine`::
+
+    engine = create_engine("oracle://scott:tiger@dsn",
+                           implicit_returning=False)
+
+Implicit returning can also be disabled on a table-by-table basis as a table
+option::
+
+    # Core Table
+    my_table = Table("my_table", metadata, ..., implicit_returning=False)
+
+
+    # declarative
+    class MyClass(Base):
+        __tablename__ = 'my_table'
+        __table_args__ = {"implicit_returning": False}
+
+.. seealso::
+
+    :ref:`cx_oracle_returning` - additional cx_oracle-specific restrictions on
+    implicit returning.
+
+ON UPDATE CASCADE
+-----------------
+
+Oracle doesn't have native ON UPDATE CASCADE functionality.  A trigger based
+solution is available at
+http://asktom.oracle.com/tkyte/update_cascade/index.html .
+
+When using the SQLAlchemy ORM, the ORM has limited ability to manually issue
+cascading updates - specify ForeignKey objects using the
+"deferrable=True, initially='deferred'" keyword arguments,
+and specify "passive_updates=False" on each relationship().
+
+Oracle 8 Compatibility
+----------------------
+
+When Oracle 8 is detected, the dialect internally configures itself to the
+following behaviors:
+
+* the use_ansi flag is set to False.  This has the effect of converting all
+  JOIN phrases into the WHERE clause, and in the case of LEFT OUTER JOIN
+  makes use of Oracle's (+) operator.
+
+* the NVARCHAR2 and NCLOB datatypes are no longer generated as DDL when
+  the :class:`~sqlalchemy.types.Unicode` is used - VARCHAR2 and CLOB are
+  issued instead.   This because these types don't seem to work correctly on
+  Oracle 8 even though they are available.  The
+  :class:`~sqlalchemy.types.NVARCHAR` and
+  :class:`~sqlalchemy.dialects.oracle.NCLOB` types will always generate
+  NVARCHAR2 and NCLOB.
+
+* the "native unicode" mode is disabled when using cx_oracle, i.e. SQLAlchemy
+  encodes all Python unicode objects to "string" before passing in as bind
+  parameters.
+
+Synonym/DBLINK Reflection
+-------------------------
+
+When using reflection with Table objects, the dialect can optionally search
+for tables indicated by synonyms, either in local or remote schemas or
+accessed over DBLINK, by passing the flag ``oracle_resolve_synonyms=True`` as
+a keyword argument to the :class:`.Table` construct::
+
+    some_table = Table('some_table', autoload=True,
+                                autoload_with=some_engine,
+                                oracle_resolve_synonyms=True)
+
+When this flag is set, the given name (such as ``some_table`` above) will
+be searched not just in the ``ALL_TABLES`` view, but also within the
+``ALL_SYNONYMS`` view to see if this name is actually a synonym to another
+name.  If the synonym is located and refers to a DBLINK, the oracle dialect
+knows how to locate the table's information using DBLINK syntax(e.g.
+``@dblink``).
+
+``oracle_resolve_synonyms`` is accepted wherever reflection arguments are
+accepted, including methods such as :meth:`.MetaData.reflect` and
+:meth:`.Inspector.get_columns`.
+
+If synonyms are not in use, this flag should be left disabled.
+
+DateTime Compatibility
+----------------------
+
+Oracle has no datatype known as ``DATETIME``, it instead has only ``DATE``,
+which can actually store a date and time value.  For this reason, the Oracle
+dialect provides a type :class:`.oracle.DATE` which is a subclass of
+:class:`.DateTime`.   This type has no special behavior, and is only
+present as a "marker" for this type; additionally, when a database column
+is reflected and the type is reported as ``DATE``, the time-supporting
+:class:`.oracle.DATE` type is used.
+
+.. versionchanged:: 0.9.4 Added :class:`.oracle.DATE` to subclass
+   :class:`.DateTime`.  This is a change as previous versions
+   would reflect a ``DATE`` column as :class:`.types.DATE`, which subclasses
+   :class:`.Date`.   The only significance here is for schemes that are
+   examining the type of column for use in special Python translations or
+   for migrating schemas to other database backends.

+
+Additional Connect Arguments
+----------------------------
+
+When connecting with ``dbname`` present, the host, port, and dbname tokens are
+converted to a TNS name using
+the cx_oracle ``makedsn()`` function.  Otherwise, the host token is taken
+directly as a TNS name.
+
+Additional arguments which may be specified either as query string arguments
+on the URL, or as keyword arguments to :func:`.create_engine()` are:
+
+* ``allow_twophase`` - enable two-phase transactions.  Defaults to ``True``.
+
+* ``arraysize`` - set the cx_oracle.arraysize value on cursors, defaulted
+  to 50.  This setting is significant with cx_Oracle as the contents of LOB
+  objects are only readable within a "live" row (e.g. within a batch of
+  50 rows).
+
+* ``auto_convert_lobs`` - defaults to True; See :ref:`cx_oracle_lob`.
+
+* ``auto_setinputsizes`` - the cx_oracle.setinputsizes() call is issued for
+  all bind parameters.  This is required for LOB datatypes but can be
+  disabled to reduce overhead.  Defaults to ``True``.  Specific types
+  can be excluded from this process using the ``exclude_setinputsizes``
+  parameter.
+
+* ``coerce_to_unicode`` - see :ref:`cx_oracle_unicode` for detail.
+
+* ``coerce_to_decimal`` - see :ref:`cx_oracle_numeric` for detail.
+
+* ``exclude_setinputsizes`` - a tuple or list of string DBAPI type names to

+  must match DBAPI types that are found in the "cx_Oracle" module namespace,
+  such as cx_Oracle.UNICODE, cx_Oracle.NCLOB, etc.   Defaults to
+  ``(STRING, UNICODE)``.
+
+  .. versionadded:: 0.8 specific DBAPI types can be excluded from the

+  alternatively an integer value.  This value is only available as a URL query
+  string argument.
+
+* ``threaded`` - enable multithreaded access to cx_oracle connections.
+  Defaults to ``True``.  Note that this is the opposite default of the
+  cx_Oracle DBAPI itself.
+
+.. _cx_oracle_unicode:
+
+Unicode
+-------
+
+The cx_Oracle DBAPI as of version 5 fully supports unicode, and has the
+ability to return string results as Python unicode objects natively.
+
+When used in Python 3, cx_Oracle returns all strings as Python unicode objects
+(that is, plain ``str`` in Python 3).  In Python 2, it will return as Python
+unicode those column values that are of type ``NVARCHAR`` or ``NCLOB``.  For
+column values that are of type ``VARCHAR`` or other non-unicode string types,
+it will return values as Python strings (e.g. bytestrings).
+
+The cx_Oracle SQLAlchemy dialect presents two different options for the use
+case of returning ``VARCHAR`` column values as Python unicode objects under
+Python 2:
+
+* the cx_Oracle DBAPI has the ability to coerce all string results to Python
+  unicode objects unconditionally using output type handlers.  This has
+  the advantage that the unicode conversion is global to all statements
+  at the cx_Oracle driver level, meaning it works with raw textual SQL
+  statements that have no typing information associated.  However, this system
+  has been observed to incur signfiicant performance overhead, not only
+  because it takes effect for all string values unconditionally, but also
+  because cx_Oracle under Python 2 seems to use a pure-Python function call in
+  order to do the decode operation, which under cPython can orders of
+  magnitude slower than doing it using C functions alone.
+
+* SQLAlchemy has unicode-decoding services built in, and when using
+  SQLAlchemy's C extensions, these functions do not use any Python function
+  calls and are very fast.  The disadvantage to this approach is that the
+  unicode conversion only takes effect for statements where the
+  :class:`.Unicode` type or :class:`.String` type with
+  ``convert_unicode=True`` is explicitly associated with the result column.
+  This is the case for any ORM or Core query or SQL expression as well as for
+  a :func:`.text` construct that specifies output column types, so in the vast
+  majority of cases this is not an issue. However, when sending a completely
+  raw string to :meth:`.Connection.execute`, this typing information isn't
+  present, unless the string is handled within a :func:`.text` construct that
+  adds typing information.
+
+As of version 0.9.2 of SQLAlchemy, the default approach is to use SQLAlchemy's
+typing system.  This keeps cx_Oracle's expensive Python 2 approach
+disabled unless the user explicitly wants it.  Under Python 3, SQLAlchemy
+detects that cx_Oracle is returning unicode objects natively and cx_Oracle's
+system is used.
+
+To re-enable cx_Oracle's output type handler under Python 2, the
+``coerce_to_unicode=True`` flag (new in 0.9.4) can be passed to
+:func:`.create_engine`::
+
+    engine = create_engine("oracle+cx_oracle://dsn", coerce_to_unicode=True)
+
+Alternatively, to run a pure string SQL statement and get ``VARCHAR`` results
+as Python unicode under Python 2 without using cx_Oracle's native handlers,
+the :func:`.text` feature can be used::
+
+    from sqlalchemy import text, Unicode
+    result = conn.execute(
+        text("select username from user").columns(username=Unicode))
+
+.. versionchanged:: 0.9.2 cx_Oracle's outputtypehandlers are no longer used
+   for unicode results of non-unicode datatypes in Python 2, after they were
+   identified as a major performance bottleneck.  SQLAlchemy's own unicode
+   facilities are used instead.
+
+.. versionadded:: 0.9.4 Added the ``coerce_to_unicode`` flag, to re-enable
+   cx_Oracle's outputtypehandler and revert to pre-0.9.2 behavior.
+
+.. _cx_oracle_returning:
+
+RETURNING Support
+-----------------
+
+The cx_oracle DBAPI supports a limited subset of Oracle's already limited
+RETURNING support.  Typically, results can only be guaranteed for at most one
+column being returned; this is the typical case when SQLAlchemy uses RETURNING
+to get just the value of a primary-key-associated sequence value.
+Additional column expressions will cause problems in a non-determinative way,
+due to cx_oracle's lack of support for the OCI_DATA_AT_EXEC API which is
+required for more complex RETURNING scenarios.
+
+For this reason, stability may be enhanced by disabling RETURNING support
+completely; SQLAlchemy otherwise will use RETURNING to fetch newly
+sequence-generated primary keys.  As illustrated in :ref:`oracle_returning`::
+
+    engine = create_engine("oracle://scott:tiger@dsn",
+                           implicit_returning=False)
+
+.. seealso::
+
+    http://docs.oracle.com/cd/B10501_01/appdev.920/a96584/oci05bnd.htm#420693
+    - OCI documentation for RETURNING
+
+    http://sourceforge.net/mailarchive/message.php?msg_id=31338136
+    - cx_oracle developer commentary
+
+.. _cx_oracle_lob:
+
+LOB Objects
+-----------
+
+cx_oracle returns oracle LOBs using the cx_oracle.LOB object.  SQLAlchemy
+converts these to strings so that the interface of the Binary type is
+consistent with that of other backends, and so that the linkage to a live
+cursor is not needed in scenarios like result.fetchmany() and
+result.fetchall().   This means that by default, LOB objects are fully fetched
+unconditionally by SQLAlchemy, and the linkage to a live cursor is broken.
+
+To disable this processing, pass ``auto_convert_lobs=False`` to
+:func:`.create_engine()`.
+
+Two Phase Transaction Support
+-----------------------------
+
+Two Phase transactions are implemented using XA transactions, and are known
+to work in a rudimental fashion with recent versions of cx_Oracle
+as of SQLAlchemy 0.8.0b2, 0.7.10.   However, the mechanism is not yet
+considered to be robust and should still be regarded as experimental.
+
+In particular, the cx_Oracle DBAPI as recently as 5.1.2 has a bug regarding
+two phase which prevents
+a particular DBAPI connection from being consistently usable in both
+prepared transactions as well as traditional DBAPI usage patterns; therefore
+once a particular connection is used via :meth:`.Connection.begin_prepared`,
+all subsequent usages of the underlying DBAPI connection must be within
+the context of prepared transactions.
+
+The default behavior of :class:`.Engine` is to maintain a pool of DBAPI
+connections.  Therefore, due to the above glitch, a DBAPI connection that has
+been used in a two-phase operation, and is then returned to the pool, will
+not be usable in a non-two-phase context.   To avoid this situation,
+the application can make one of several choices:
+
+* Disable connection pooling using :class:`.NullPool`
+
+* Ensure that the particular :class:`.Engine` in use is only used
+  for two-phase operations.   A :class:`.Engine` bound to an ORM
+  :class:`.Session` which includes ``twophase=True`` will consistently
+  use the two-phase transaction style.
+
+* For ad-hoc two-phase operations without disabling pooling, the DBAPI
+  connection in use can be evicted from the connection pool using the
+  :meth:`.Connection.detach` method.
+
+.. versionchanged:: 0.8.0b2,0.7.10
+    Support for cx_oracle prepared transactions has been implemented
+    and tested.
+
+.. _cx_oracle_numeric:
+
+Precision Numerics
+------------------
+
+The SQLAlchemy dialect goes through a lot of steps to ensure
+that decimal numbers are sent and received with full accuracy.
+An "outputtypehandler" callable is associated with each
+cx_oracle connection object which detects numeric types and
+receives them as string values, instead of receiving a Python
+``float`` directly, which is then passed to the Python
+``Decimal`` constructor.  The :class:`.Numeric` and
+:class:`.Float` types under the cx_oracle dialect are aware of
+this behavior, and will coerce the ``Decimal`` to ``float`` if
+the ``asdecimal`` flag is ``False`` (default on :class:`.Float`,
+optional on :class:`.Numeric`).
+
+Because the handler coerces to ``Decimal`` in all cases first,
+the feature can detract significantly from performance.
+If precision numerics aren't required, the decimal handling
+can be disabled by passing the flag ``coerce_to_decimal=False``
+to :func:`.create_engine`::
+
+    engine = create_engine("oracle+cx_oracle://dsn", coerce_to_decimal=False)
+
+.. versionadded:: 0.7.6
+    Add the ``coerce_to_decimal`` flag.
+
+Another alternative to performance is to use the
+`cdecimal <http://pypi.python.org/pypi/cdecimal/>`_ library;
+see :class:`.Numeric` for additional notes.
+
+The handler attempts to use the "precision" and "scale"
+attributes of the result set column to best determine if
+subsequent incoming values should be received as ``Decimal`` as
+opposed to int (in which case no processing is added). There are
+several scenarios where OCI_ does not provide unambiguous data
+as to the numeric type, including some situations where
+individual rows may return a combination of floating point and
+integer values. Certain values for "precision" and "scale" have
+been observed to determine this scenario.  When it occurs, the
+outputtypehandler receives as string and then passes off to a
+processing function which detects, for each returned value, if a
+decimal point is present, and if so converts to ``Decimal``,
+otherwise to int.  The intention is that simple int-based
+statements like "SELECT my_seq.nextval() FROM DUAL" continue to
+return ints and not ``Decimal`` objects, and that any kind of
+floating point value is received as a string so that there is no
+floating point loss of precision.
+
+The "decimal point is present" logic itself is also sensitive to
+locale.  Under OCI_, this is controlled by the NLS_LANG
+environment variable. Upon first connection, the dialect runs a
+test to determine the current "decimal" character, which can be
+a comma "," for European locales. From that point forward the
+outputtypehandler uses that character to represent a decimal
+point. Note that cx_oracle 5.0.3 or greater is required
+when dealing with numerics with locale settings that don't use
+a period "." as the decimal character.
+
+.. versionchanged:: 0.6.6
+    The outputtypehandler supports the case where the locale uses a
+    comma "," character to represent a decimal point.

+.. dialect:: postgresql
+    :name: PostgreSQL
+
+
+Sequences/SERIAL
+----------------
+
+PostgreSQL supports sequences, and SQLAlchemy uses these as the default means
+of creating new primary key values for integer-based primary key columns. When
+creating tables, SQLAlchemy will issue the ``SERIAL`` datatype for
+integer-based primary key columns, which generates a sequence and server side
+default corresponding to the column.
+
+To specify a specific named sequence to be used for primary key generation,
+use the :func:`~sqlalchemy.schema.Sequence` construct::
+
+    Table('sometable', metadata,
+            Column('id', Integer, Sequence('some_id_seq'), primary_key=True)
+        )
+
+When SQLAlchemy issues a single INSERT statement, to fulfill the contract of
+having the "last insert identifier" available, a RETURNING clause is added to
+the INSERT statement which specifies the primary key columns should be
+returned after the statement completes. The RETURNING functionality only takes
+place if Postgresql 8.2 or later is in use. As a fallback approach, the
+sequence, whether specified explicitly or implicitly via ``SERIAL``, is
+executed independently beforehand, the returned value to be used in the
+subsequent insert. Note that when an
+:func:`~sqlalchemy.sql.expression.insert()` construct is executed using
+"executemany" semantics, the "last inserted identifier" functionality does not
+apply; no RETURNING clause is emitted nor is the sequence pre-executed in this
+case.
+
+To force the usage of RETURNING by default off, specify the flag
+``implicit_returning=False`` to :func:`.create_engine`.
+
+.. _postgresql_isolation_level:
+
+Transaction Isolation Level
+---------------------------
+
+All Postgresql dialects support setting of transaction isolation level
+both via a dialect-specific parameter ``isolation_level``
+accepted by :func:`.create_engine`,
+as well as the ``isolation_level`` argument as passed to
+:meth:`.Connection.execution_options`.  When using a non-psycopg2 dialect,
+this feature works by issuing the command
+``SET SESSION CHARACTERISTICS AS TRANSACTION ISOLATION LEVEL <level>`` for
+each new connection.
+
+To set isolation level using :func:`.create_engine`::
+
+    engine = create_engine(
+        "postgresql+pg8000://scott:tiger@localhost/test",
+        isolation_level="READ UNCOMMITTED"
+    )
+
+To set using per-connection execution options::
+
+    connection = engine.connect()
+    connection = connection.execution_options(
+        isolation_level="READ COMMITTED"
+    )
+
+Valid values for ``isolation_level`` include:
+
+* ``READ COMMITTED``
+* ``READ UNCOMMITTED``
+* ``REPEATABLE READ``
+* ``SERIALIZABLE``
+
+The :mod:`~sqlalchemy.dialects.postgresql.psycopg2` and
+:mod:`~sqlalchemy.dialects.postgresql.pg8000` dialects also offer the
+special level ``AUTOCOMMIT``.
+
+.. seealso::
+
+    :ref:`psycopg2_isolation_level`
+
+    :ref:`pg8000_isolation_level`
+
+.. _postgresql_schema_reflection:
+
+Remote-Schema Table Introspection and Postgresql search_path
+------------------------------------------------------------
+
+The Postgresql dialect can reflect tables from any schema.  The
+:paramref:`.Table.schema` argument, or alternatively the
+:paramref:`.MetaData.reflect.schema` argument determines which schema will
+be searched for the table or tables.   The reflected :class:`.Table` objects
+will in all cases retain this ``.schema`` attribute as was specified.
+However, with regards to tables which these :class:`.Table` objects refer to
+via foreign key constraint, a decision must be made as to how the ``.schema``
+is represented in those remote tables, in the case where that remote
+schema name is also a member of the current
+`Postgresql search path
+<http://www.postgresql.org/docs/9.0/static/ddl-schemas.html#DDL-SCHEMAS-PATH>`_.
+
+By default, the Postgresql dialect mimics the behavior encouraged by
+Postgresql's own ``pg_get_constraintdef()`` builtin procedure.  This function
+returns a sample definition for a particular foreign key constraint,
+omitting the referenced schema name from that definition when the name is
+also in the Postgresql schema search path.  The interaction below
+illustrates this behavior::
+
+    test=> CREATE TABLE test_schema.referred(id INTEGER PRIMARY KEY);
+    CREATE TABLE
+    test=> CREATE TABLE referring(
+    test(>         id INTEGER PRIMARY KEY,
+    test(>         referred_id INTEGER REFERENCES test_schema.referred(id));
+    CREATE TABLE
+    test=> SET search_path TO public, test_schema;
+    test=> SELECT pg_catalog.pg_get_constraintdef(r.oid, true) FROM
+    test-> pg_catalog.pg_class c JOIN pg_catalog.pg_namespace n
+    test-> ON n.oid = c.relnamespace
+    test-> JOIN pg_catalog.pg_constraint r  ON c.oid = r.conrelid
+    test-> WHERE c.relname='referring' AND r.contype = 'f'
+    test-> ;
+                   pg_get_constraintdef
+    ---------------------------------------------------
+     FOREIGN KEY (referred_id) REFERENCES referred(id)
+    (1 row)
+
+Above, we created a table ``referred`` as a member of the remote schema
+``test_schema``, however when we added ``test_schema`` to the
+PG ``search_path`` and then asked ``pg_get_constraintdef()`` for the
+``FOREIGN KEY`` syntax, ``test_schema`` was not included in the output of
+the function.
+
+On the other hand, if we set the search path back to the typical default
+of ``public``::
+
+    test=> SET search_path TO public;
+    SET
+
+The same query against ``pg_get_constraintdef()`` now returns the fully
+schema-qualified name for us::
+
+    test=> SELECT pg_catalog.pg_get_constraintdef(r.oid, true) FROM
+    test-> pg_catalog.pg_class c JOIN pg_catalog.pg_namespace n
+    test-> ON n.oid = c.relnamespace
+    test-> JOIN pg_catalog.pg_constraint r  ON c.oid = r.conrelid
+    test-> WHERE c.relname='referring' AND r.contype = 'f';
+                         pg_get_constraintdef
+    ---------------------------------------------------------------
+     FOREIGN KEY (referred_id) REFERENCES test_schema.referred(id)
+    (1 row)
+
+SQLAlchemy will by default use the return value of ``pg_get_constraintdef()``
+in order to determine the remote schema name.  That is, if our ``search_path``
+were set to include ``test_schema``, and we invoked a table
+reflection process as follows::
+
+    >>> from sqlalchemy import Table, MetaData, create_engine
+    >>> engine = create_engine("postgresql://scott:tiger@localhost/test")
+    >>> with engine.connect() as conn:
+    ...     conn.execute("SET search_path TO test_schema, public")
+    ...     meta = MetaData()
+    ...     referring = Table('referring', meta,
+    ...                       autoload=True, autoload_with=conn)
+    ...
+    <sqlalchemy.engine.result.ResultProxy object at 0x101612ed0>
+
+The above process would deliver to the :attr:`.MetaData.tables` collection
+``referred`` table named **without** the schema::
+
+    >>> meta.tables['referred'].schema is None
+    True
+
+To alter the behavior of reflection such that the referred schema is
+maintained regardless of the ``search_path`` setting, use the
+``postgresql_ignore_search_path`` option, which can be specified as a
+dialect-specific argument to both :class:`.Table` as well as
+:meth:`.MetaData.reflect`::
+
+    >>> with engine.connect() as conn:
+    ...     conn.execute("SET search_path TO test_schema, public")

+
+.. sidebar:: Best Practices for Postgresql Schema reflection
+
+    The description of Postgresql schema reflection behavior is complex, and
+    is the product of many years of dealing with widely varied use cases and
+    user preferences. But in fact, there's no need to understand any of it if
+    you just stick to the simplest use pattern: leave the ``search_path`` set
+    to its default of ``public`` only, never refer to the name ``public`` as
+    an explicit schema name otherwise, and refer to all other schema names
+    explicitly when building up a :class:`.Table` object.  The options
+    described here are only for those users who can't, or prefer not to, stay
+    within these guidelines.
+
+Note that **in all cases**, the "default" schema is always reflected as
+``None``. The "default" schema on Postgresql is that which is returned by the
+Postgresql ``current_schema()`` function.  On a typical Postgresql
+installation, this is the name ``public``.  So a table that refers to another
+which is in the ``public`` (i.e. default) schema will always have the
+``.schema`` attribute set to ``None``.
+
+.. versionadded:: 0.9.2 Added the ``postgresql_ignore_search_path``
+   dialect-level option accepted by :class:`.Table` and
+   :meth:`.MetaData.reflect`.
+
+
+.. seealso::
+
+        `The Schema Search Path
+        <http://www.postgresql.org/docs/9.0/static/ddl-schemas.html#DDL-SCHEMAS-PATH>`_
+        - on the Postgresql website.
+
+INSERT/UPDATE...RETURNING
+-------------------------
+
+The dialect supports PG 8.2's ``INSERT..RETURNING``, ``UPDATE..RETURNING`` and
+``DELETE..RETURNING`` syntaxes.   ``INSERT..RETURNING`` is used by default
+for single-row INSERT statements in order to fetch newly generated
+primary key identifiers.   To specify an explicit ``RETURNING`` clause,
+use the :meth:`._UpdateBase.returning` method on a per-statement basis::
+
+    # INSERT..RETURNING
+    result = table.insert().returning(table.c.col1, table.c.col2).\\
+        values(name='foo')
+    print result.fetchall()
+
+    # UPDATE..RETURNING
+    result = table.update().returning(table.c.col1, table.c.col2).\\
+        where(table.c.name=='foo').values(name='bar')
+    print result.fetchall()
+
+    # DELETE..RETURNING
+    result = table.delete().returning(table.c.col1, table.c.col2).\\
+        where(table.c.name=='foo')
+    print result.fetchall()
+
+.. _postgresql_match:
+
+Full Text Search
+----------------
+
+SQLAlchemy makes available the Postgresql ``@@`` operator via the
+:meth:`.ColumnElement.match` method on any textual column expression.
+On a Postgresql dialect, an expression like the following::
+
+    select([sometable.c.text.match("search string")])
+
+will emit to the database::
+
+    SELECT text @@ to_tsquery('search string') FROM table
+
+The Postgresql text search functions such as ``to_tsquery()``
+and ``to_tsvector()`` are available
+explicitly using the standard :attr:`.func` construct.  For example::
+
+    select([
+        func.to_tsvector('fat cats ate rats').match('cat & rat')
+    ])
+
+Emits the equivalent of::
+
+    SELECT to_tsvector('fat cats ate rats') @@ to_tsquery('cat & rat')
+
+The :class:`.postgresql.TSVECTOR` type can provide for explicit CAST::
+
+    from sqlalchemy.dialects.postgresql import TSVECTOR
+    from sqlalchemy import select, cast
+    select([cast("some text", TSVECTOR)])
+
+produces a statement equivalent to::
+
+    SELECT CAST('some text' AS TSVECTOR) AS anon_1
+
+Full Text Searches in Postgresql are influenced by a combination of: the
+PostgresSQL setting of ``default_text_search_config``, the ``regconfig`` used
+to build the GIN/GiST indexes, and the ``regconfig`` optionally passed in
+during a query.
+
+When performing a Full Text Search against a column that has a GIN or
+GiST index that is already pre-computed (which is common on full text
+searches) one may need to explicitly pass in a particular PostgresSQL
+``regconfig`` value to ensure the query-planner utilizes the index and does
+not re-compute the column on demand.
+
+In order to provide for this explicit query planning, or to use different
+search strategies, the ``match`` method accepts a ``postgresql_regconfig``
+keyword argument.
+
+    select([mytable.c.id]).where(
+        mytable.c.title.match('somestring', postgresql_regconfig='english')
+    )
+
+Emits the equivalent of::
+
+    SELECT mytable.id FROM mytable
+    WHERE mytable.title @@ to_tsquery('english', 'somestring')
+
+One can also specifically pass in a `'regconfig'` value to the
+``to_tsvector()`` command as the initial argument.
+
+    select([mytable.c.id]).where(
+            func.to_tsvector('english', mytable.c.title )\
+            .match('somestring', postgresql_regconfig='english')
+        )
+
+produces a statement equivalent to::
+
+    SELECT mytable.id FROM mytable
+    WHERE to_tsvector('english', mytable.title) @@
+        to_tsquery('english', 'somestring')
+
+It is recommended that you use the ``EXPLAIN ANALYZE...`` tool from
+PostgresSQL to ensure that you are generating queries with SQLAlchemy that
+take full advantage of any indexes you may have created for full text search.
+
+FROM ONLY ...
+------------------------
+
+The dialect supports PostgreSQL's ONLY keyword for targeting only a particular
+table in an inheritance hierarchy. This can be used to produce the
+``SELECT ... FROM ONLY``, ``UPDATE ONLY ...``, and ``DELETE FROM ONLY ...``
+syntaxes. It uses SQLAlchemy's hints mechanism::
+
+    # SELECT ... FROM ONLY ...
+    result = table.select().with_hint(table, 'ONLY', 'postgresql')
+    print result.fetchall()
+
+    # UPDATE ONLY ...
+    table.update(values=dict(foo='bar')).with_hint('ONLY',
+                                                   dialect_name='postgresql')
+
+    # DELETE FROM ONLY ...
+    table.delete().with_hint('ONLY', dialect_name='postgresql')
+
+.. _postgresql_indexes:
+
+Postgresql-Specific Index Options
+---------------------------------
+
+Several extensions to the :class:`.Index` construct are available, specific
+to the PostgreSQL dialect.
+
+Partial Indexes
+^^^^^^^^^^^^^^^^
+
+Partial indexes add criterion to the index definition so that the index is
+applied to a subset of rows.   These can be specified on :class:`.Index`
+using the ``postgresql_where`` keyword argument::
+
+  Index('my_index', my_table.c.id, postgresql_where=tbl.c.value > 10)
+
+Operator Classes
+^^^^^^^^^^^^^^^^^
+
+PostgreSQL allows the specification of an *operator class* for each column of
+an index (see
+http://www.postgresql.org/docs/8.3/interactive/indexes-opclass.html).
+The :class:`.Index` construct allows these to be specified via the
+``postgresql_ops`` keyword argument::
+
+    Index('my_index', my_table.c.id, my_table.c.data,
+                            postgresql_ops={
+                                'data': 'text_pattern_ops',
+                                'id': 'int4_ops'
+                            })
+
+.. versionadded:: 0.7.2
+    ``postgresql_ops`` keyword argument to :class:`.Index` construct.
+
+Note that the keys in the ``postgresql_ops`` dictionary are the "key" name of
+the :class:`.Column`, i.e. the name used to access it from the ``.c``
+collection of :class:`.Table`, which can be configured to be different than
+the actual name of the column as expressed in the database.
+
+Index Types
+^^^^^^^^^^^^
+
+PostgreSQL provides several index types: B-Tree, Hash, GiST, and GIN, as well
+as the ability for users to create their own (see
+http://www.postgresql.org/docs/8.3/static/indexes-types.html). These can be
+specified on :class:`.Index` using the ``postgresql_using`` keyword argument::
+
+    Index('my_index', my_table.c.data, postgresql_using='gin')
+
+The value passed to the keyword argument will be simply passed through to the
+underlying CREATE INDEX command, so it *must* be a valid index type for your
+version of PostgreSQL.

+Unicode
+-------
+
+When communicating with the server, pg8000 **always uses the server-side
+character set**.  SQLAlchemy has no ability to modify what character set
+pg8000 chooses to use, and additionally SQLAlchemy does no unicode conversion
+of any kind with the pg8000 backend. The origin of the client encoding setting
+is ultimately the CLIENT_ENCODING setting in postgresql.conf.
+
+It is not necessary, though is also harmless, to pass the "encoding" parameter
+to :func:`.create_engine` when using pg8000.

+
+psycopg2 Connect Arguments
+-----------------------------------
+
+psycopg2-specific keyword arguments which are accepted by
+:func:`.create_engine()` are:
+
+* ``server_side_cursors``: Enable the usage of "server side cursors" for SQL
+  statements which support this feature. What this essentially means from a
+  psycopg2 point of view is that the cursor is created using a name, e.g.
+  ``connection.cursor('some name')``, which has the effect that result rows
+  are not immediately pre-fetched and buffered after statement execution, but
+  are instead left on the server and only retrieved as needed. SQLAlchemy's
+  :class:`~sqlalchemy.engine.ResultProxy` uses special row-buffering
+  behavior when this feature is enabled, such that groups of 100 rows at a
+  time are fetched over the wire to reduce conversational overhead.
+  Note that the ``stream_results=True`` execution option is a more targeted
+  way of enabling this mode on a per-execution basis.
+* ``use_native_unicode``: Enable the usage of Psycopg2 "native unicode" mode
+  per connection.  True by default.
+* ``isolation_level``: This option, available for all PostgreSQL dialects,
+  includes the ``AUTOCOMMIT`` isolation level when using the psycopg2
+  dialect.  See :ref:`psycopg2_isolation_level`.
+
+
+Unix Domain Connections
+------------------------
+
+psycopg2 supports connecting via Unix domain connections.   When the ``host``
+portion of the URL is omitted, SQLAlchemy passes ``None`` to psycopg2,
+which specifies Unix-domain communication rather than TCP/IP communication::
+
+    create_engine("postgresql+psycopg2://user:password@/dbname")
+
+By default, the socket file used is to connect to a Unix-domain socket
+in ``/tmp``, or whatever socket directory was specified when PostgreSQL
+was built.  This value can be overridden by passing a pathname to psycopg2,
+using ``host`` as an additional keyword argument::
+
+    create_engine("postgresql+psycopg2://user:password@/dbname?host=/var/lib/postgresql")
+
+See also:
+
+`PQconnectdbParams <http://www.postgresql.org/docs/9.1/static\
+/libpq-connect.html#LIBPQ-PQCONNECTDBPARAMS>`_
+
+Per-Statement/Connection Execution Options
+-------------------------------------------
+
+The following DBAPI-specific options are respected when used with
+:meth:`.Connection.execution_options`, :meth:`.Executable.execution_options`,
+:meth:`.Query.execution_options`, in addition to those not specific to DBAPIs:
+
+* isolation_level - Set the transaction isolation level for the lifespan of a
+  :class:`.Connection` (can only be set on a connection, not a statement
+  or query).   See :ref:`psycopg2_isolation_level`.
+
+* stream_results - Enable or disable usage of psycopg2 server side cursors -
+  this feature makes use of "named" cursors in combination with special
+  result handling methods so that result rows are not fully buffered.
+  If ``None`` or not set, the ``server_side_cursors`` option of the
+  :class:`.Engine` is used.
+
+Unicode
+-------
+
+By default, the psycopg2 driver uses the ``psycopg2.extensions.UNICODE``
+extension, such that the DBAPI receives and returns all strings as Python
+Unicode objects directly - SQLAlchemy passes these values through without
+change.   Psycopg2 here will encode/decode string values based on the
+current "client encoding" setting; by default this is the value in
+the ``postgresql.conf`` file, which often defaults to ``SQL_ASCII``.
+Typically, this can be changed to ``utf-8``, as a more useful default::
+
+    #client_encoding = sql_ascii # actually, defaults to database
+                                 # encoding
+    client_encoding = utf8
+
+A second way to affect the client encoding is to set it within Psycopg2
+locally.   SQLAlchemy will call psycopg2's ``set_client_encoding()``
+method (see:
+http://initd.org/psycopg/docs/connection.html#connection.set_client_encoding)
+on all new connections based on the value passed to
+:func:`.create_engine` using the ``client_encoding`` parameter::
+
+    engine = create_engine("postgresql://user:pass@host/dbname",
+                           client_encoding='utf8')
+
+This overrides the encoding specified in the Postgresql client configuration.
+
+.. versionadded:: 0.7.3
+    The psycopg2-specific ``client_encoding`` parameter to
+    :func:`.create_engine`.
+
+SQLAlchemy can also be instructed to skip the usage of the psycopg2
+``UNICODE`` extension and to instead utilize its own unicode encode/decode
+services, which are normally reserved only for those DBAPIs that don't
+fully support unicode directly.  Passing ``use_native_unicode=False`` to
+:func:`.create_engine` will disable usage of ``psycopg2.extensions.UNICODE``.
+SQLAlchemy will instead encode data itself into Python bytestrings on the way
+in and coerce from bytes on the way back,
+using the value of the :func:`.create_engine` ``encoding`` parameter, which
+defaults to ``utf-8``.
+SQLAlchemy's own unicode encode/decode functionality is steadily becoming
+obsolete as more DBAPIs support unicode fully along with the approach of
+Python 3; in modern usage psycopg2 should be relied upon to handle unicode.
+
+Transactions
+------------
+
+The psycopg2 dialect fully supports SAVEPOINT and two-phase commit operations.
+
+.. _psycopg2_isolation_level:
+
+Psycopg2 Transaction Isolation Level
+-------------------------------------
+
+As discussed in :ref:`postgresql_isolation_level`,
+all Postgresql dialects support setting of transaction isolation level
+both via the ``isolation_level`` parameter passed to :func:`.create_engine`,
+as well as the ``isolation_level`` argument used by
+:meth:`.Connection.execution_options`.  When using the psycopg2 dialect, these
+options make use of psycopg2's ``set_isolation_level()`` connection method,
+rather than emitting a Postgresql directive; this is because psycopg2's
+API-level setting is always emitted at the start of each transaction in any
+case.
+
+The psycopg2 dialect supports these constants for isolation level:
+
+* ``READ COMMITTED``
+* ``READ UNCOMMITTED``
+* ``REPEATABLE READ``
+* ``SERIALIZABLE``
+* ``AUTOCOMMIT``
+
+.. versionadded:: 0.8.2 support for AUTOCOMMIT isolation level when using
+   psycopg2.
+
+.. seealso::
+
+    :ref:`postgresql_isolation_level`
+
+    :ref:`pg8000_isolation_level`
+
+
+NOTICE logging
+---------------
+
+The psycopg2 dialect will log Postgresql NOTICE messages via the
+``sqlalchemy.dialects.postgresql`` logger::
+
+    import logging
+    logging.getLogger('sqlalchemy.dialects.postgresql').setLevel(logging.INFO)
+
+.. _psycopg2_hstore::
+
+HSTORE type
+------------
+
+The ``psycopg2`` DBAPI includes an extension to natively handle marshalling of
+the HSTORE type.   The SQLAlchemy psycopg2 dialect will enable this extension
+by default when it is detected that the target database has the HSTORE
+type set up for use.   In other words, when the dialect makes the first
+connection, a sequence like the following is performed:
+
+1. Request the available HSTORE oids using
+   ``psycopg2.extras.HstoreAdapter.get_oids()``.
+   If this function returns a list of HSTORE identifiers, we then determine
+   that the ``HSTORE`` extension is present.
+
+2. If the ``use_native_hstore`` flag is at its default of ``True``, and
+   we've detected that ``HSTORE`` oids are available, the
+   ``psycopg2.extensions.register_hstore()`` extension is invoked for all
+   connections.
+
+The ``register_hstore()`` extension has the effect of **all Python
+dictionaries being accepted as parameters regardless of the type of target
+column in SQL**. The dictionaries are converted by this extension into a
+textual HSTORE expression.  If this behavior is not desired, disable the
+use of the hstore extension by setting ``use_native_hstore`` to ``False`` as
+follows::
+
+    engine = create_engine("postgresql+psycopg2://scott:tiger@localhost/test",
+                use_native_hstore=False)
+
+The ``HSTORE`` type is **still supported** when the
+``psycopg2.extensions.register_hstore()`` extension is not used.  It merely
+means that the coercion between Python dictionaries and the HSTORE
+string format, on both the parameter side and the result side, will take
+place within SQLAlchemy's own marshalling logic, and not that of ``psycopg2``
+which may be more performant.

+.. dialect:: sqlite
+    :name: SQLite
+
+
+Date and Time Types
+-------------------
+
+SQLite does not have built-in DATE, TIME, or DATETIME types, and pysqlite does
+not provide out of the box functionality for translating values between Python
+`datetime` objects and a SQLite-supported format. SQLAlchemy's own
+:class:`~sqlalchemy.types.DateTime` and related types provide date formatting
+and parsing functionality when SQlite is used. The implementation classes are
+:class:`~.sqlite.DATETIME`, :class:`~.sqlite.DATE` and :class:`~.sqlite.TIME`.
+These types represent dates and times as ISO formatted strings, which also
+nicely support ordering. There's no reliance on typical "libc" internals for
+these functions so historical dates are fully supported.
+
+.. _sqlite_autoincrement:
+
+SQLite Auto Incrementing Behavior
+----------------------------------
+
+Background on SQLite's autoincrement is at: http://sqlite.org/autoinc.html
+
+Two things to note:
+
+* The AUTOINCREMENT keyword is **not** required for SQLite tables to
+  generate primary key values automatically. AUTOINCREMENT only means that the
+  algorithm used to generate ROWID values should be slightly different.
+* SQLite does **not** generate primary key (i.e. ROWID) values, even for
+  one column, if the table has a composite (i.e. multi-column) primary key.
+  This is regardless of the AUTOINCREMENT keyword being present or not.
+
+To specifically render the AUTOINCREMENT keyword on the primary key column
+when rendering DDL, add the flag ``sqlite_autoincrement=True`` to the Table
+construct::
+
+    Table('sometable', metadata,
+            Column('id', Integer, primary_key=True),
+            sqlite_autoincrement=True)
+
+Transaction Isolation Level
+---------------------------
+
+:func:`.create_engine` accepts an ``isolation_level`` parameter which results
+in the command ``PRAGMA read_uncommitted <level>`` being invoked for every new
+connection. Valid values for this parameter are ``SERIALIZABLE`` and ``READ
+UNCOMMITTED`` corresponding to a value of 0 and 1, respectively. See the
+section :ref:`pysqlite_serializable` for an important workaround when using
+serializable isolation with Pysqlite.
+
+Database Locking Behavior / Concurrency
+---------------------------------------
+
+Note that SQLite is not designed for a high level of concurrency. The database
+itself, being a file, is locked completely during write operations and within
+transactions, meaning exactly one connection has exclusive access to the
+database during this period - all other connections will be blocked during
+this time.
+
+The Python DBAPI specification also calls for a connection model that is
+always in a transaction; there is no BEGIN method, only commit and rollback.
+This implies that a SQLite DBAPI driver would technically allow only
+serialized access to a particular database file at all times. The pysqlite
+driver attempts to ameliorate this by deferring the actual BEGIN statement
+until the first DML (INSERT, UPDATE, or DELETE) is received within a
+transaction. While this breaks serializable isolation, it at least delays the
+exclusive locking inherent in SQLite's design.
+
+SQLAlchemy's default mode of usage with the ORM is known as
+"autocommit=False", which means the moment the :class:`.Session` begins to be
+used, a transaction is begun. As the :class:`.Session` is used, the autoflush
+feature, also on by default, will flush out pending changes to the database
+before each query. The effect of this is that a :class:`.Session` used in its
+default mode will often emit DML early on, long before the transaction is
+actually committed. This again will have the effect of serializing access to
+the SQLite database. If highly concurrent reads are desired against the SQLite
+database, it is advised that the autoflush feature be disabled, and
+potentially even that autocommit be re-enabled, which has the effect of each
+SQL statement and flush committing changes immediately.
+
+For more information on SQLite's lack of concurrency by design, please see
+`Situations Where Another RDBMS May Work Better - High Concurrency
+<http://www.sqlite.org/whentouse.html>`_ near the bottom of the page.
+
+.. _sqlite_foreign_keys:
+
+Foreign Key Support
+-------------------
+
+SQLite supports FOREIGN KEY syntax when emitting CREATE statements for tables,
+however by default these constraints have no effect on the operation of the
+table.
+
+Constraint checking on SQLite has three prerequisites:
+
+* At least version 3.6.19 of SQLite must be in use
+* The SQLite library must be compiled *without* the SQLITE_OMIT_FOREIGN_KEY
+  or SQLITE_OMIT_TRIGGER symbols enabled.
+* The ``PRAGMA foreign_keys = ON`` statement must be emitted on all
+  connections before use.
+
+SQLAlchemy allows for the ``PRAGMA`` statement to be emitted automatically for
+new connections through the usage of events::
+
+    from sqlalchemy.engine import Engine
+    from sqlalchemy import event
+
+    @event.listens_for(Engine, "connect")
+    def set_sqlite_pragma(dbapi_connection, connection_record):
+        cursor = dbapi_connection.cursor()
+        cursor.execute("PRAGMA foreign_keys=ON")
+        cursor.close()
+
+.. seealso::
+
+    `SQLite Foreign Key Support <http://www.sqlite.org/foreignkeys.html>`_
+    - on the SQLite web site.
+
+    :ref:`event_toplevel` - SQLAlchemy event API.
+
+.. _sqlite_type_reflection:
+
+Type Reflection
+---------------
+
+SQLite types are unlike those of most other database backends, in that
+the string name of the type usually does not correspond to a "type" in a
+one-to-one fashion.  Instead, SQLite links per-column typing behavior
+to one of five so-called "type affinities" based on a string matching
+pattern for the type.
+
+SQLAlchemy's reflection process, when inspecting types, uses a simple
+lookup table to link the keywords returned to provided SQLAlchemy types.
+This lookup table is present within the SQLite dialect as it is for all
+other dialects.  However, the SQLite dialect has a different "fallback"
+routine for when a particular type name is not located in the lookup map;
+it instead implements the SQLite "type affinity" scheme located at
+http://www.sqlite.org/datatype3.html section 2.1.
+
+The provided typemap will make direct associations from an exact string
+name match for the following types:
+

+.. dialect:: sqlite+pysqlite
+    :name: pysqlite
+    :dbapi: sqlite3
+    :connectstring: sqlite+pysqlite:///file_path
+    :url: http://docs.python.org/library/sqlite3.html
+
+    Note that ``pysqlite`` is the same driver as the ``sqlite3``
+    module included with the Python distribution.
+
+Driver
+------
+
+When using Python 2.5 and above, the built in ``sqlite3`` driver is
+already installed and no additional installation is needed.  Otherwise,
+the ``pysqlite2`` driver needs to be present.  This is the same driver as
+``sqlite3``, just with a different name.
+
+The ``pysqlite2`` driver will be loaded first, and if not found, ``sqlite3``
+is loaded.  This allows an explicitly installed pysqlite driver to take
+precedence over the built in one.   As with all dialects, a specific
+DBAPI module may be provided to :func:`~sqlalchemy.create_engine()` to control
+this explicitly::
+
+    from sqlite3 import dbapi2 as sqlite
+    e = create_engine('sqlite+pysqlite:///file.db', module=sqlite)
+
+
+Connect Strings
+---------------
+
+The file specification for the SQLite database is taken as the "database"
+portion of the URL.  Note that the format of a SQLAlchemy url is::
+
+    driver://user:pass@host/database
+
+This means that the actual filename to be used starts with the characters to
+the **right** of the third slash.   So connecting to a relative filepath
+looks like::
+
+    # relative path
+    e = create_engine('sqlite:///path/to/database.db')
+
+An absolute path, which is denoted by starting with a slash, means you
+need **four** slashes::
+
+    # absolute path
+    e = create_engine('sqlite:////path/to/database.db')
+
+To use a Windows path, regular drive specifications and backslashes can be
+used. Double backslashes are probably needed::
+
+    # absolute path on Windows
+    e = create_engine('sqlite:///C:\\\\path\\\\to\\\\database.db')
+
+The sqlite ``:memory:`` identifier is the default if no filepath is
+present.  Specify ``sqlite://`` and nothing else::
+
+    # in-memory database
+    e = create_engine('sqlite://')
+
+Compatibility with sqlite3 "native" date and datetime types
+-----------------------------------------------------------
+
+The pysqlite driver includes the sqlite3.PARSE_DECLTYPES and
+sqlite3.PARSE_COLNAMES options, which have the effect of any column
+or expression explicitly cast as "date" or "timestamp" will be converted
+to a Python date or datetime object.  The date and datetime types provided
+with the pysqlite dialect are not currently compatible with these options,
+since they render the ISO date/datetime including microseconds, which
+pysqlite's driver does not.   Additionally, SQLAlchemy does not at
+this time automatically render the "cast" syntax required for the
+freestanding functions "current_timestamp" and "current_date" to return
+datetime/date types natively.   Unfortunately, pysqlite
+does not provide the standard DBAPI types in ``cursor.description``,
+leaving SQLAlchemy with no way to detect these types on the fly
+without expensive per-row type checks.
+
+Keeping in mind that pysqlite's parsing option is not recommended,
+nor should be necessary, for use with SQLAlchemy, usage of PARSE_DECLTYPES
+can be forced if one configures "native_datetime=True" on create_engine()::
+
+    engine = create_engine('sqlite://',
+        connect_args={'detect_types':
+            sqlite3.PARSE_DECLTYPES|sqlite3.PARSE_COLNAMES},
+        native_datetime=True
+    )
+
+With this flag enabled, the DATE and TIMESTAMP types (but note - not the
+DATETIME or TIME types...confused yet ?) will not perform any bind parameter
+or result processing. Execution of "func.current_date()" will return a string.
+"func.current_timestamp()" is registered as returning a DATETIME type in
+SQLAlchemy, so this function still receives SQLAlchemy-level result
+processing.
+
+.. _pysqlite_threading_pooling:
+
+Threading/Pooling Behavior
+---------------------------
+
+Pysqlite's default behavior is to prohibit the usage of a single connection
+in more than one thread.   This is originally intended to work with older
+versions of SQLite that did not support multithreaded operation under
+various circumstances.  In particular, older SQLite versions
+did not allow a ``:memory:`` database to be used in multiple threads
+under any circumstances.
+
+Pysqlite does include a now-undocumented flag known as
+``check_same_thread`` which will disable this check, however note that
+pysqlite connections are still not safe to use in concurrently in multiple
+threads.  In particular, any statement execution calls would need to be
+externally mutexed, as Pysqlite does not provide for thread-safe propagation
+of error messages among other things.   So while even ``:memory:`` databases
+can be shared among threads in modern SQLite, Pysqlite doesn't provide enough
+thread-safety to make this usage worth it.
+
+SQLAlchemy sets up pooling to work with Pysqlite's default behavior:
+
+* When a ``:memory:`` SQLite database is specified, the dialect by default
+  will use :class:`.SingletonThreadPool`. This pool maintains a single
+  connection per thread, so that all access to the engine within the current
+  thread use the same ``:memory:`` database - other threads would access a
+  different ``:memory:`` database.
+* When a file-based database is specified, the dialect will use
+  :class:`.NullPool` as the source of connections. This pool closes and
+  discards connections which are returned to the pool immediately. SQLite
+  file-based connections have extremely low overhead, so pooling is not
+  necessary. The scheme also prevents a connection from being used again in
+  a different thread and works best with SQLite's coarse-grained file locking.
+
+  .. versionchanged:: 0.7
+      Default selection of :class:`.NullPool` for SQLite file-based databases.
+      Previous versions select :class:`.SingletonThreadPool` by
+      default for all SQLite databases.
+
+
+Using a Memory Database in Multiple Threads
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To use a ``:memory:`` database in a multithreaded scenario, the same
+connection object must be shared among threads, since the database exists
+only within the scope of that connection.   The
+:class:`.StaticPool` implementation will maintain a single connection
+globally, and the ``check_same_thread`` flag can be passed to Pysqlite
+as ``False``::
+
+    from sqlalchemy.pool import StaticPool
+    engine = create_engine('sqlite://',
+                        connect_args={'check_same_thread':False},
+                        poolclass=StaticPool)
+
+Note that using a ``:memory:`` database in multiple threads requires a recent
+version of SQLite.
+
+Using Temporary Tables with SQLite
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Due to the way SQLite deals with temporary tables, if you wish to use a
+temporary table in a file-based SQLite database across multiple checkouts
+from the connection pool, such as when using an ORM :class:`.Session` where
+the temporary table should continue to remain after :meth:`.Session.commit` or
+:meth:`.Session.rollback` is called, a pool which maintains a single
+connection must be used.   Use :class:`.SingletonThreadPool` if the scope is
+only needed within the current thread, or :class:`.StaticPool` is scope is
+needed within multiple threads for this case::
+
+    # maintain the same connection per thread
+    from sqlalchemy.pool import SingletonThreadPool
+    engine = create_engine('sqlite:///mydb.db',
+                        poolclass=SingletonThreadPool)
+
+
+    # maintain the same connection across all threads
+    from sqlalchemy.pool import StaticPool
+    engine = create_engine('sqlite:///mydb.db',
+                        poolclass=StaticPool)
+
+Note that :class:`.SingletonThreadPool` should be configured for the number
+of threads that are to be used; beyond that number, connections will be
+closed out in a non deterministic way.
+
+Unicode
+-------
+
+The pysqlite driver only returns Python ``unicode`` objects in result sets,
+never plain strings, and accommodates ``unicode`` objects within bound
+parameter values in all cases.   Regardless of the SQLAlchemy string type in
+use, string-based result values will by Python ``unicode`` in Python 2.
+The :class:`.Unicode` type should still be used to indicate those columns that
+require unicode, however, so that non-``unicode`` values passed inadvertently
+will emit a warning.  Pysqlite will emit an error if a non-``unicode`` string
+is passed containing non-ASCII characters.
+
+.. _pysqlite_serializable:
+
+Serializable Transaction Isolation
+----------------------------------
+
+The pysqlite DBAPI driver has a long-standing bug in which transactional
+state is not begun until the first DML statement, that is INSERT, UPDATE
+or DELETE, is emitted.  A SELECT statement will not cause transactional
+state to begin.   While this mode of usage is fine for typical situations
+and has the advantage that the SQLite database file is not prematurely
+locked, it breaks serializable transaction isolation, which requires
+that the database file be locked upon any SQL being emitted.
+
+To work around this issue, the ``BEGIN`` keyword can be emitted
+at the start of each transaction.   The following recipe establishes
+a :meth:`.ConnectionEvents.begin` handler to achieve this::
+
+    from sqlalchemy import create_engine, event
+
+    engine = create_engine("sqlite:///myfile.db",
+                           isolation_level='SERIALIZABLE')
+
+    @event.listens_for(engine, "begin")
+    def do_begin(conn):
+        conn.execute("BEGIN")

+"""SQL connections, SQL execution and high-level DB-API interface.
+
+The engine package defines the basic components used to interface
+DB-API modules with higher-level statement construction,
+connection-management, execution and result contexts.  The primary
+"entry point" class into this package is the Engine and its public
+constructor ``create_engine()``.
+
+This package includes:
+
+base.py
+    Defines interface classes and some implementation classes which
+    comprise the basic components used to interface between a DB-API,
+    constructed and plain-text statements, connections, transactions,
+    and results.
+
+default.py
+    Contains default implementations of some of the components defined
+    in base.py.  All current database dialects use the classes in
+    default.py as base classes for their own database-specific
+    implementations.
+
+strategies.py
+    The mechanics of constructing ``Engine`` objects are represented
+    here.  Defines the ``EngineStrategy`` class which represents how
+    to go from arguments specified to the ``create_engine()``
+    function, to a fully constructed ``Engine``, including
+    initialization of connection pooling, dialects, and specific
+    subclasses of ``Engine``.
+
+threadlocal.py
+    The ``TLEngine`` class is defined here, which is a subclass of
+    the generic ``Engine`` and tracks ``Connection`` and
+    ``Transaction`` objects against the identity of the current
+    thread.  This allows certain programming patterns based around
+    the concept of a "thread-local connection" to be possible.
+    The ``TLEngine`` is created by using the "threadlocal" engine
+    strategy in conjunction with the ``create_engine()`` function.
+
+url.py
+    Defines the ``URL`` class which represents the individual
+    components of a string URL passed to ``create_engine()``.  Also
+    defines a basic module-loading strategy for the dialect specifier
+    within a URL.

+def create_engine(*args, **kwargs):
+    """Create a new :class:`.Engine` instance.
+
+    The standard calling form is to send the URL as the
+    first positional argument, usually a string
+    that indicates database dialect and connection arguments::
+
+
+        engine = create_engine("postgresql://scott:tiger@localhost/test")
+
+    Additional keyword arguments may then follow it which
+    establish various options on the resulting :class:`.Engine`
+    and its underlying :class:`.Dialect` and :class:`.Pool`
+    constructs::
+
+        engine = create_engine("mysql://scott:tiger@hostname/dbname",
+                                    encoding='latin1', echo=True)
+
+    The string form of the URL is
+    ``dialect[+driver]://user:password@host/dbname[?key=value..]``, where
+    ``dialect`` is a database name such as ``mysql``, ``oracle``,
+    ``postgresql``, etc., and ``driver`` the name of a DBAPI, such as
+    ``psycopg2``, ``pyodbc``, ``cx_oracle``, etc.  Alternatively,
+    the URL can be an instance of :class:`~sqlalchemy.engine.url.URL`.
+
+    ``**kwargs`` takes a wide variety of options which are routed
+    towards their appropriate components.  Arguments may be specific to
+    the :class:`.Engine`, the underlying :class:`.Dialect`, as well as the
+    :class:`.Pool`.  Specific dialects also accept keyword arguments that
+    are unique to that dialect.   Here, we describe the parameters
+    that are common to most :func:`.create_engine()` usage.
+
+    Once established, the newly resulting :class:`.Engine` will
+    request a connection from the underlying :class:`.Pool` once
+    :meth:`.Engine.connect` is called, or a method which depends on it
+    such as :meth:`.Engine.execute` is invoked.   The :class:`.Pool` in turn
+    will establish the first actual DBAPI connection when this request
+    is received.   The :func:`.create_engine` call itself does **not**
+    establish any actual DBAPI connections directly.
+
+    .. seealso::
+
+        :doc:`/core/engines`
+
+        :doc:`/dialects/index`
+
+        :ref:`connections_toplevel`
+
+    :param case_sensitive=True: if False, result column names
+       will match in a case-insensitive fashion, that is,
+       ``row['SomeColumn']``.
+
+       .. versionchanged:: 0.8
+           By default, result row names match case-sensitively.
+           In version 0.7 and prior, all matches were case-insensitive.
+
+    :param connect_args: a dictionary of options which will be
+        passed directly to the DBAPI's ``connect()`` method as
+        additional keyword arguments.  See the example
+        at :ref:`custom_dbapi_args`.
+
+    :param convert_unicode=False: if set to True, sets
+        the default behavior of ``convert_unicode`` on the
+        :class:`.String` type to ``True``, regardless
+        of a setting of ``False`` on an individual
+        :class:`.String` type, thus causing all :class:`.String`
+        -based columns
+        to accommodate Python ``unicode`` objects.  This flag
+        is useful as an engine-wide setting when using a
+        DBAPI that does not natively support Python
+        ``unicode`` objects and raises an error when
+        one is received (such as pyodbc with FreeTDS).
+
+        See :class:`.String` for further details on
+        what this flag indicates.
+
+    :param creator: a callable which returns a DBAPI connection.
+        This creation function will be passed to the underlying
+        connection pool and will be used to create all new database
+        connections. Usage of this function causes connection
+        parameters specified in the URL argument to be bypassed.
+
+    :param echo=False: if True, the Engine will log all statements
+        as well as a repr() of their parameter lists to the engines
+        logger, which defaults to sys.stdout. The ``echo`` attribute of
+        ``Engine`` can be modified at any time to turn logging on and
+        off. If set to the string ``"debug"``, result rows will be
+        printed to the standard output as well. This flag ultimately
+        controls a Python logger; see :ref:`dbengine_logging` for
+        information on how to configure logging directly.
+
+    :param echo_pool=False: if True, the connection pool will log
+        all checkouts/checkins to the logging stream, which defaults to
+        sys.stdout. This flag ultimately controls a Python logger; see
+        :ref:`dbengine_logging` for information on how to configure logging
+        directly.
+
+    :param encoding: Defaults to ``utf-8``.  This is the string
+        encoding used by SQLAlchemy for string encode/decode
+        operations which occur within SQLAlchemy, **outside of
+        the DBAPI.**  Most modern DBAPIs feature some degree of
+        direct support for Python ``unicode`` objects,
+        what you see in Python 2 as a string of the form
+        ``u'some string'``.  For those scenarios where the
+        DBAPI is detected as not supporting a Python ``unicode``
+        object, this encoding is used to determine the
+        source/destination encoding.  It is **not used**
+        for those cases where the DBAPI handles unicode
+        directly.
+
+        To properly configure a system to accommodate Python
+        ``unicode`` objects, the DBAPI should be
+        configured to handle unicode to the greatest
+        degree as is appropriate - see
+        the notes on unicode pertaining to the specific
+        target database in use at :ref:`dialect_toplevel`.
+
+        Areas where string encoding may need to be accommodated
+        outside of the DBAPI include zero or more of:
+
+        * the values passed to bound parameters, corresponding to
+          the :class:`.Unicode` type or the :class:`.String` type
+          when ``convert_unicode`` is ``True``;
+        * the values returned in result set columns corresponding
+          to the :class:`.Unicode` type or the :class:`.String`
+          type when ``convert_unicode`` is ``True``;
+        * the string SQL statement passed to the DBAPI's
+          ``cursor.execute()`` method;
+        * the string names of the keys in the bound parameter
+          dictionary passed to the DBAPI's ``cursor.execute()``
+          as well as ``cursor.setinputsizes()`` methods;
+        * the string column names retrieved from the DBAPI's
+          ``cursor.description`` attribute.
+
+        When using Python 3, the DBAPI is required to support
+        *all* of the above values as Python ``unicode`` objects,
+        which in Python 3 are just known as ``str``.  In Python 2,
+        the DBAPI does not specify unicode behavior at all,
+        so SQLAlchemy must make decisions for each of the above
+        values on a per-DBAPI basis - implementations are
+        completely inconsistent in their behavior.
+
+    :param execution_options: Dictionary execution options which will
+        be applied to all connections.  See
+        :meth:`~sqlalchemy.engine.Connection.execution_options`
+
+    :param implicit_returning=True: When ``True``, a RETURNING-
+        compatible construct, if available, will be used to
+        fetch newly generated primary key values when a single row
+        INSERT statement is emitted with no existing returning()
+        clause.  This applies to those backends which support RETURNING
+        or a compatible construct, including Postgresql, Firebird, Oracle,
+        Microsoft SQL Server.   Set this to ``False`` to disable
+        the automatic usage of RETURNING.
+
+    :param label_length=None: optional integer value which limits
+        the size of dynamically generated column labels to that many
+        characters. If less than 6, labels are generated as
+        "_(counter)". If ``None``, the value of
+        ``dialect.max_identifier_length`` is used instead.
+
+    :param listeners: A list of one or more
+        :class:`~sqlalchemy.interfaces.PoolListener` objects which will
+        receive connection pool events.
+
+    :param logging_name:  String identifier which will be used within
+        the "name" field of logging records generated within the
+        "sqlalchemy.engine" logger. Defaults to a hexstring of the
+        object's id.
+
+    :param max_overflow=10: the number of connections to allow in
+        connection pool "overflow", that is connections that can be
+        opened above and beyond the pool_size setting, which defaults
+        to five. this is only used with :class:`~sqlalchemy.pool.QueuePool`.
+
+    :param module=None: reference to a Python module object (the module
+        itself, not its string name).  Specifies an alternate DBAPI module to
+        be used by the engine's dialect.  Each sub-dialect references a
+        specific DBAPI which will be imported before first connect.  This
+        parameter causes the import to be bypassed, and the given module to
+        be used instead. Can be used for testing of DBAPIs as well as to
+        inject "mock" DBAPI implementations into the :class:`.Engine`.
+
+    :param pool=None: an already-constructed instance of
+        :class:`~sqlalchemy.pool.Pool`, such as a
+        :class:`~sqlalchemy.pool.QueuePool` instance. If non-None, this
+        pool will be used directly as the underlying connection pool
+        for the engine, bypassing whatever connection parameters are
+        present in the URL argument. For information on constructing
+        connection pools manually, see :ref:`pooling_toplevel`.
+
+    :param poolclass=None: a :class:`~sqlalchemy.pool.Pool`
+        subclass, which will be used to create a connection pool
+        instance using the connection parameters given in the URL. Note
+        this differs from ``pool`` in that you don't actually
+        instantiate the pool in this case, you just indicate what type
+        of pool to be used.
+
+    :param pool_logging_name:  String identifier which will be used within
+       the "name" field of logging records generated within the
+       "sqlalchemy.pool" logger. Defaults to a hexstring of the object's
+       id.
+
+    :param pool_size=5: the number of connections to keep open
+        inside the connection pool. This used with
+        :class:`~sqlalchemy.pool.QueuePool` as
+        well as :class:`~sqlalchemy.pool.SingletonThreadPool`.  With
+        :class:`~sqlalchemy.pool.QueuePool`, a ``pool_size`` setting
+        of 0 indicates no limit; to disable pooling, set ``poolclass`` to
+        :class:`~sqlalchemy.pool.NullPool` instead.
+
+    :param pool_recycle=-1: this setting causes the pool to recycle
+        connections after the given number of seconds has passed. It
+        defaults to -1, or no timeout. For example, setting to 3600
+        means connections will be recycled after one hour. Note that
+        MySQL in particular will disconnect automatically if no
+        activity is detected on a connection for eight hours (although
+        this is configurable with the MySQLDB connection itself and the
+        server configuration as well).
+
+    :param pool_reset_on_return='rollback': set the "reset on return"
+        behavior of the pool, which is whether ``rollback()``,
+        ``commit()``, or nothing is called upon connections
+        being returned to the pool.  See the docstring for
+        ``reset_on_return`` at :class:`.Pool`.
+
+        .. versionadded:: 0.7.6
+
+    :param pool_timeout=30: number of seconds to wait before giving
+        up on getting a connection from the pool. This is only used
+        with :class:`~sqlalchemy.pool.QueuePool`.
+
+    :param strategy='plain': selects alternate engine implementations.
+        Currently available are:
+
+        * the ``threadlocal`` strategy, which is described in
+          :ref:`threadlocal_strategy`;
+        * the ``mock`` strategy, which dispatches all statement
+          execution to a function passed as the argument ``executor``.
+          See `example in the FAQ
+          <http://www.sqlalchemy.org/trac/wiki/FAQ#HowcanIgettheCREATETABLEDROPTABLEoutputasastring>`_.
+
+    :param executor=None: a function taking arguments
+        ``(sql, *multiparams, **params)``, to which the ``mock`` strategy will
+        dispatch all statement execution. Used only by ``strategy='mock'``.

+          connections by default are always in a transaction - SQLAlchemy uses
+          rules applied to different kinds of statements to determine if
+          COMMIT will be invoked in order to provide its "autocommit" feature.
+          Typically, all INSERT/UPDATE/DELETE statements as well as
+          CREATE/DROP statements have autocommit behavior enabled; SELECT
+          constructs do not. Use this option when invoking a SELECT or other
+          specific SQL construct where COMMIT is desired (typically when
+          calling stored procedures and such), and an explicit
+          transaction is not in progress.
+
+        :param compiled_cache: Available on: Connection.
+          A dictionary where :class:`.Compiled` objects
+          will be cached when the :class:`.Connection` compiles a clause
+          expression into a :class:`.Compiled` object.
+          It is the user's responsibility to
+          manage the size of this dictionary, which will have keys
+          corresponding to the dialect, clause element, the column
+          names within the VALUES or SET clause of an INSERT or UPDATE,
+          as well as the "batch" mode for an INSERT or UPDATE statement.
+          The format of this dictionary is not guaranteed to stay the
+          same in future releases.
+
+          Note that the ORM makes use of its own "compiled" caches for
+          some operations, including flush operations.  The caching
+          used by the ORM internally supersedes a cache dictionary
+          specified here.
+
+        :param isolation_level: Available on: Connection.
+          Set the transaction isolation level for
+          the lifespan of this connection.   Valid values include
+          those string values accepted by the ``isolation_level``
+          parameter passed to :func:`.create_engine`, and are
+          database specific, including those for :ref:`sqlite_toplevel`,
+          :ref:`postgresql_toplevel` - see those dialect's documentation
+          for further info.
+
+          Note that this option necessarily affects the underlying
+          DBAPI connection for the lifespan of the originating
+          :class:`.Connection`, and is not per-execution. This
+          setting is not removed until the underlying DBAPI connection
+          is returned to the connection pool, i.e.
+          the :meth:`.Connection.close` method is called.
+
+        :param no_parameters: When ``True``, if the final parameter
+          list or dictionary is totally empty, will invoke the
+          statement on the cursor as ``cursor.execute(statement)``,
+          not passing the parameter collection at all.
+          Some DBAPIs such as psycopg2 and mysql-python consider
+          percent signs as significant only when parameters are
+          present; this option allows code to generate SQL
+          containing percent signs (and possibly other characters)
+          that is neutral regarding whether it's executed by the DBAPI
+          or piped into a script that's later invoked by
+          command line tools.
+
+          .. versionadded:: 0.7.6
+
+        :param stream_results: Available on: Connection, statement.
+          Indicate to the dialect that results should be
+          "streamed" and not pre-buffered, if possible.  This is a limitation
+          of many DBAPIs.  The flag is currently understood only by the
+          psycopg2 dialect.

+
+        The returned :class:`.Engine` remains related to the original
+        :class:`.Engine` in that it shares the same connection pool and
+        other state:
+
+        * The :class:`.Pool` used by the new :class:`.Engine` is the
+          same instance.  The :meth:`.Engine.dispose` method will replace
+          the connection pool instance for the parent engine as well
+          as this one.
+        * Event listeners are "cascaded" - meaning, the new :class:`.Engine`
+          inherits the events of the parent, and new events can be associated
+          with the new :class:`.Engine` individually.
+        * The logging configuration and logging_name is copied from the parent
+          :class:`.Engine`.
+
+        The intent of the :meth:`.Engine.execution_options` method is
+        to implement "sharding" schemes where multiple :class:`.Engine`
+        objects refer to the same connection pool, but are differentiated
+        by options that would be consumed by a custom event::
+
+            primary_engine = create_engine("mysql://")
+            shard1 = primary_engine.execution_options(shard_id="shard1")
+            shard2 = primary_engine.execution_options(shard_id="shard2")
+
+        Above, the ``shard1`` engine serves as a factory for
+        :class:`.Connection` objects that will contain the execution option
+        ``shard_id=shard1``, and ``shard2`` will produce :class:`.Connection`
+        objects that contain the execution option ``shard_id=shard2``.
+
+        An event handler can consume the above execution option to perform
+        a schema switch or other operation, given a connection.  Below
+        we emit a MySQL ``use`` statement to switch databases, at the same
+        time keeping track of which database we've established using the
+        :attr:`.Connection.info` dictionary, which gives us a persistent
+        storage space that follows the DBAPI connection::

+    To implement, establish as a series of tuples, as in::
+
+        construct_arguments = [
+            (schema.Index, {
+                "using": False,
+                "where": None,
+                "ops": None
+            })
+        ]
+
+    If the above construct is established on the Postgresql dialect,
+    the :class:`.Index` construct will now accept the keyword arguments
+    ``postgresql_using``, ``postgresql_where``, nad ``postgresql_ops``.
+    Any other argument specified to the constructor of :class:`.Index`
+    which is prefixed with ``postgresql_`` will raise :class:`.ArgumentError`.
+
+    A dialect which does not include a ``construct_arguments`` member will
+    not participate in the argument validation system.  For such a dialect,
+    any argument name is accepted by all participating constructs, within
+    the namespace of arguments prefixed with that dialect name.  The rationale
+    here is so that third-party dialects that haven't yet implemented this
+    feature continue to function in the old way.

+"""Provides an abstraction for obtaining database schema information.
+
+Usage Notes:
+
+Here are some general conventions when accessing the low level inspector
+methods such as get_table_names, get_columns, etc.
+
+1. Inspector methods return lists of dicts in most cases for the following
+   reasons:
+
+   * They're both standard types that can be serialized.
+   * Using a dict instead of a tuple allows easy expansion of attributes.
+   * Using a list for the outer structure maintains order and is easy to work
+     with (e.g. list comprehension [d['name'] for d in cols]).
+
+2. Records that contain a name, such as the column name in a column record
+   use the key 'name'. So for most return values, each record will have a
+   'name' attribute..

+"""Attribute implementation for _Dispatch classes.
+
+The various listener targets for a particular event class are represented
+as attributes, which refer to collections of listeners to be fired off.
+These collections can exist at the class level as well as at the instance
+level.  An event is fired off using code like this::
+
+    some_object.dispatch.first_connect(arg1, arg2)
+
+Above, ``some_object.dispatch`` would be an instance of ``_Dispatch`` and
+``first_connect`` is typically an instance of ``_ListenerCollection``
+if event listeners are present, or ``_EmptyListener`` if none are present.
+
+The attribute mechanics here spend effort trying to ensure listener functions
+are available with a minimum of function call overhead, that unnecessary
+objects aren't created (i.e. many empty per-instance listener collections),
+as well as that everything is garbage collectable when owning references are
+lost.  Other features such as "propagation" of listener functions across
+many ``_Dispatch`` instances, "joining" of multiple ``_Dispatch`` instances,
+as well as support for subclass propagation (e.g. events assigned to
+``Pool`` vs. ``QueuePool``) are all implemented here.

+
+    :class:`.MetaData` and :class:`.Table` support events
+    specifically regarding when CREATE and DROP
+    DDL is emitted to the database.
+
+    Attachment events are also provided to customize

+    with its :class:`.Table`, when a :class:`.ForeignKeyConstraint`
+    is associated with a :class:`.Table`, etc.

+        result row fetching, cursor creation.
+
+        Note that :meth:`.handle_error` may support new kinds of exceptions
+        and new calling scenarios at *any time*.  Code which uses this
+        event must expect new calling patterns to be present in minor
+        releases.
+
+        To support the wide variety of members that correspond to an exception,
+        as well as to allow extensibility of the event without backwards
+        incompatibility, the sole argument received is an instance of
+        :class:`.ExceptionContext`.   This object contains data members
+        representing detail about the exception.
+
+        Use cases supported by this hook include:
+
+        * read-only, low-level exception handling for logging and
+          debugging purposes
+        * exception re-writing
+
+        The hook is called while the cursor from the failed operation
+        (if any) is still open and accessible.   Special cleanup operations
+        can be called on this cursor; SQLAlchemy will attempt to close
+        this cursor subsequent to this hook being invoked.  If the connection
+        is in "autocommit" mode, the transaction also remains open within
+        the scope of this hook; the rollback of the per-statement transaction
+        also occurs after the hook is called.
+
+        The user-defined event handler has two options for replacing
+        the SQLAlchemy-constructed exception into one that is user
+        defined.   It can either raise this new exception directly, in
+        which case all further event listeners are bypassed and the
+        exception will be raised, after appropriate cleanup as taken
+        place::
+
+            @event.listens_for(Engine, "handle_error")
+            def handle_exception(context):
+                if isinstance(context.original_exception,
+                    psycopg2.OperationalError) and \\
+                    "failed" in str(context.original_exception):
+                    raise MySpecialException("failed operation")
+
+        Alternatively, a "chained" style of event handling can be
+        used, by configuring the handler with the ``retval=True``
+        modifier and returning the new exception instance from the
+        function.  In this case, event handling will continue onto the
+        next handler.   The "chained" exception is available using
+        :attr:`.ExceptionContext.chained_exception`::
+
+            @event.listens_for(Engine, "handle_error", retval=True)
+            def handle_exception(context):
+                if context.chained_exception is not None and \\
+                    "special" in context.chained_exception.message:
+                    return MySpecialException("failed",
+                        cause=context.chained_exception)
+
+        Handlers that return ``None`` may remain within this chain; the
+        last non-``None`` return value is the one that continues to be
+        passed to the next handler.
+
+        When a custom exception is raised or returned, SQLAlchemy raises
+        this new exception as-is, it is not wrapped by any SQLAlchemy
+        object.  If the exception is not a subclass of
+        :class:`sqlalchemy.exc.StatementError`,
+        certain features may not be available; currently this includes
+        the ORM's feature of adding a detail hint about "autoflush" to
+        exceptions raised within the autoflush process.
+

+
+    The returned value is an instance of :class:`.AssociationProxy`.
+
+    Implements a Python property representing a relationship as a collection
+    of simpler values, or a scalar value.  The proxied property will mimic
+    the collection type of the target (list, dict or set), or, in the case of
+    a one to one relationship, a simple scalar value.
+
+    :param target_collection: Name of the attribute we'll proxy to.
+      This attribute is typically mapped by
+      :func:`~sqlalchemy.orm.relationship` to link to a target collection, but
+      can also be a many-to-one or non-scalar relationship.
+
+    :param attr: Attribute on the associated instance or instances we'll
+      proxy for.
+
+      For example, given a target collection of [obj1, obj2], a list created

+      the class collected by the target collection will be created.  For list
+      and set collections, the target class constructor will be called with
+      the 'value' for the new instance.  For dict types, two arguments are
+      passed: key and value.
+
+      If you want to construct instances differently, supply a *creator*
+      function that takes arguments as above and returns instances.
+
+      For scalar relationships, creator() will be called if the target is None.
+      If the target is present, set operations are proxied to setattr() on the
+      associated object.
+
+      If you have an associated object with multiple attributes, you may set
+      up multiple association proxies mapping to different attributes.  See
+      the unit tests for examples, and for examples of how creator() functions
+      can be used to construct the scalar relationship on-demand in this

+"""Define an extension to the :mod:`sqlalchemy.ext.declarative` system
+which automatically generates mapped classes and relationships from a database
+schema, typically though not necessarily one which is reflected.
+
+.. versionadded:: 0.9.1 Added :mod:`sqlalchemy.ext.automap`.
+
+.. note::
+
+    The :mod:`sqlalchemy.ext.automap` extension should be considered
+    **experimental** as of 0.9.1.   Featureset and API stability is
+    not guaranteed at this time.
+
+It is hoped that the :class:`.AutomapBase` system provides a quick
+and modernized solution to the problem that the very famous
+`SQLSoup <https://sqlsoup.readthedocs.org/en/latest/>`_
+also tries to solve, that of generating a quick and rudimentary object
+model from an existing database on the fly.  By addressing the issue strictly
+at the mapper configuration level, and integrating fully with existing
+Declarative class techniques, :class:`.AutomapBase` seeks to provide
+a well-integrated approach to the issue of expediently auto-generating ad-hoc
+mappings.
+
+
+Basic Use
+=========
+
+The simplest usage is to reflect an existing database into a new model.
+We create a new :class:`.AutomapBase` class in a similar manner as to how
+we create a declarative base class, using :func:`.automap_base`.
+We then call :meth:`.AutomapBase.prepare` on the resulting base class,
+asking it to reflect the schema and produce mappings::
+
+    from sqlalchemy.ext.automap import automap_base
+    from sqlalchemy.orm import Session
+    from sqlalchemy import create_engine
+
+    Base = automap_base()
+
+    # engine, suppose it has two tables 'user' and 'address' set up
+    engine = create_engine("sqlite:///mydatabase.db")
+
+    # reflect the tables
+    Base.prepare(engine, reflect=True)
+
+    # mapped classes are now created with names by default
+    # matching that of the table name.
+    User = Base.classes.user
+    Address = Base.classes.address
+
+    session = Session(engine)
+
+    # rudimentary relationships are produced
+    session.add(Address(email_address="foo@bar.com", user=User(name="foo")))
+    session.commit()
+
+    # collection-based relationships are by default named
+    # "<classname>_collection"
+    print (u1.address_collection)
+
+Above, calling :meth:`.AutomapBase.prepare` while passing along the
+:paramref:`.AutomapBase.prepare.reflect` parameter indicates that the
+:meth:`.MetaData.reflect` method will be called on this declarative base
+classes' :class:`.MetaData` collection; then, each viable
+:class:`.Table` within the :class:`.MetaData` will get a new mapped class
+generated automatically.  The :class:`.ForeignKeyConstraint` objects which
+link the various tables together will be used to produce new, bidirectional
+:func:`.relationship` objects between classes.   The classes and relationships
+follow along a default naming scheme that we can customize.  At this point,
+our basic mapping consisting of related ``User`` and ``Address`` classes is
+ready to use in the traditional way.
+
+Generating Mappings from an Existing MetaData
+=============================================
+
+We can pass a pre-declared :class:`.MetaData` object to :func:`.automap_base`.
+This object can be constructed in any way, including programmatically, from
+a serialized file, or from itself being reflected using
+:meth:`.MetaData.reflect`.  Below we illustrate a combination of reflection and
+explicit table declaration::
+
+    from sqlalchemy import create_engine, MetaData, Table, Column, ForeignKey
+    engine = create_engine("sqlite:///mydatabase.db")
+
+    # produce our own MetaData object
+    metadata = MetaData()
+
+    # we can reflect it ourselves from a database, using options
+    # such as 'only' to limit what tables we look at...
+    metadata.reflect(engine, only=['user', 'address'])
+
+    # ... or just define our own Table objects with it (or combine both)
+    Table('user_order', metadata,
+                    Column('id', Integer, primary_key=True),
+                    Column('user_id', ForeignKey('user.id'))
+                )
+
+    # we can then produce a set of mappings from this MetaData.
+    Base = automap_base(metadata=metadata)
+
+    # calling prepare() just sets up mapped classes and relationships.
+    Base.prepare()
+
+    # mapped classes are ready
+    User, Address, Order = Base.classes.user, Base.classes.address,\
+        Base.classes.user_order
+
+Specifying Classes Explcitly
+============================
+
+The :mod:`.sqlalchemy.ext.automap` extension allows classes to be defined
+explicitly, in a way similar to that of the :class:`.DeferredReflection` class.
+Classes that extend from :class:`.AutomapBase` act like regular declarative
+classes, but are not immediately mapped after their construction, and are
+instead mapped when we call :meth:`.AutomapBase.prepare`.  The
+:meth:`.AutomapBase.prepare` method will make use of the classes we've
+established based on the table name we use.  If our schema contains tables
+``user`` and ``address``, we can define one or both of the classes to be used::
+
+    from sqlalchemy.ext.automap import automap_base
+    from sqlalchemy import create_engine
+
+    # automap base
+    Base = automap_base()
+
+    # pre-declare User for the 'user' table
+    class User(Base):
+        __tablename__ = 'user'
+
+        # override schema elements like Columns
+        user_name = Column('name', String)
+
+        # override relationships too, if desired.
+        # we must use the same name that automap would use for the
+        # relationship, and also must refer to the class name that automap will
+        # generate for "address"
+        address_collection = relationship("address", collection_class=set)
+
+    # reflect
+    engine = create_engine("sqlite:///mydatabase.db")
+    Base.prepare(engine, reflect=True)
+
+    # we still have Address generated from the tablename "address",
+    # but User is the same as Base.classes.User now
+
+    Address = Base.classes.address
+
+    u1 = session.query(User).first()
+    print (u1.address_collection)
+
+    # the backref is still there:
+    a1 = session.query(Address).first()
+    print (a1.user)
+
+Above, one of the more intricate details is that we illustrated overriding
+one of the :func:`.relationship` objects that automap would have created.
+To do this, we needed to make sure the names match up with what automap
+would normally generate, in that the relationship name would be
+``User.address_collection`` and the name of the class referred to, from
+automap's perspective, is called ``address``, even though we are referring to
+it as ``Address`` within our usage of this class.
+
+Overriding Naming Schemes
+=========================
+
+:mod:`.sqlalchemy.ext.automap` is tasked with producing mapped classes and
+relationship names based on a schema, which means it has decision points in how
+these names are determined.  These three decision points are provided using
+functions which can be passed to the :meth:`.AutomapBase.prepare` method, and
+are known as :func:`.classname_for_table`,
+:func:`.name_for_scalar_relationship`,
+and :func:`.name_for_collection_relationship`.  Any or all of these
+functions are provided as in the example below, where we use a "camel case"
+scheme for class names and a "pluralizer" for collection names using the
+`Inflect <https://pypi.python.org/pypi/inflect>`_ package::
+
+    import re
+    import inflect
+
+    def camelize_classname(base, tablename, table):
+        "Produce a 'camelized' class name, e.g. "
+        "'words_and_underscores' -> 'WordsAndUnderscores'"
+
+        return str(tablename[0].upper() + \\
+                re.sub(r'_(\w)', lambda m: m.group(1).upper(), tablename[1:]))
+
+    _pluralizer = inflect.engine()
+    def pluralize_collection(base, local_cls, referred_cls, constraint):
+        "Produce an 'uncamelized', 'pluralized' class name, e.g. "
+        "'SomeTerm' -> 'some_terms'"
+
+        referred_name = referred_cls.__name__
+        uncamelized = referred_name[0].lower() + \\
+                        re.sub(r'\W',
+                                lambda m: "_%s" % m.group(0).lower(),
+                                referred_name[1:])
+        pluralized = _pluralizer.plural(uncamelized)
+        return pluralized
+
+    from sqlalchemy.ext.automap import automap_base
+
+    Base = automap_base()
+
+    engine = create_engine("sqlite:///mydatabase.db")
+
+    Base.prepare(engine, reflect=True,
+                classname_for_table=camelize_classname,
+                name_for_collection_relationship=pluralize_collection
+        )
+
+From the above mapping, we would now have classes ``User`` and ``Address``,
+where the collection from ``User`` to ``Address`` is called
+``User.addresses``::
+
+    User, Address = Base.classes.User, Base.classes.Address
+
+    u1 = User(addresses=[Address(email="foo@bar.com")])
+
+Relationship Detection
+======================
+
+The vast majority of what automap accomplishes is the generation of
+:func:`.relationship` structures based on foreign keys.  The mechanism
+by which this works for many-to-one and one-to-many relationships is as
+follows:
+
+1. A given :class:`.Table`, known to be mapped to a particular class,
+   is examined for :class:`.ForeignKeyConstraint` objects.
+
+2. From each :class:`.ForeignKeyConstraint`, the remote :class:`.Table`
+   object present is matched up to the class to which it is to be mapped,
+   if any, else it is skipped.
+
+3. As the :class:`.ForeignKeyConstraint` we are examining corresponds to a
+   reference from the immediate mapped class,  the relationship will be set up
+   as a many-to-one referring to the referred class; a corresponding
+   one-to-many backref will be created on the referred class referring
+   to this class.
+
+4. The names of the relationships are determined using the
+   :paramref:`.AutomapBase.prepare.name_for_scalar_relationship` and
+   :paramref:`.AutomapBase.prepare.name_for_collection_relationship`
+   callable functions.  It is important to note that the default relationship
+   naming derives the name from the **the actual class name**.  If you've
+   given a particular class an explicit name by declaring it, or specified an
+   alternate class naming scheme, that's the name from which the relationship
+   name will be derived.
+
+5. The classes are inspected for an existing mapped property matching these
+   names.  If one is detected on one side, but none on the other side,
+   :class:`.AutomapBase` attempts to create a relationship on the missing side,
+   then uses the :paramref:`.relationship.back_populates` parameter in order to
+   point the new relationship to the other side.
+
+6. In the usual case where no relationship is on either side,
+   :meth:`.AutomapBase.prepare` produces a :func:`.relationship` on the
+   "many-to-one" side and matches it to the other using the
+   :paramref:`.relationship.backref` parameter.
+
+7. Production of the :func:`.relationship` and optionally the :func:`.backref`
+   is handed off to the :paramref:`.AutomapBase.prepare.generate_relationship`
+   function, which can be supplied by the end-user in order to augment
+   the arguments passed to :func:`.relationship` or :func:`.backref` or to
+   make use of custom implementations of these functions.
+
+Custom Relationship Arguments
+-----------------------------
+
+The :paramref:`.AutomapBase.prepare.generate_relationship` hook can be used
+to add parameters to relationships.  For most cases, we can make use of the
+existing :func:`.automap.generate_relationship` function to return
+the object, after augmenting the given keyword dictionary with our own
+arguments.
+
+Below is an illustration of how to send
+:paramref:`.relationship.cascade` and
+:paramref:`.relationship.passive_deletes`
+options along to all one-to-many relationships::
+
+    from sqlalchemy.ext.automap import generate_relationship
+
+    def _gen_relationship(base, direction, return_fn,
+                                    attrname, local_cls, referred_cls, **kw):
+        if direction is interfaces.ONETOMANY:
+            kw['cascade'] = 'all, delete-orphan'
+            kw['passive_deletes'] = True
+        # make use of the built-in function to actually return
+        # the result.
+        return generate_relationship(base, direction, return_fn,
+                                     attrname, local_cls, referred_cls, **kw)
+
+    from sqlalchemy.ext.automap import automap_base
+    from sqlalchemy import create_engine
+
+    # automap base
+    Base = automap_base()
+
+    engine = create_engine("sqlite:///mydatabase.db")
+    Base.prepare(engine, reflect=True,
+                generate_relationship=_gen_relationship)
+
+Many-to-Many relationships
+--------------------------
+
+:mod:`.sqlalchemy.ext.automap` will generate many-to-many relationships, e.g.
+those which contain a ``secondary`` argument.  The process for producing these
+is as follows:
+
+1. A given :class:`.Table` is examined for :class:`.ForeignKeyConstraint`
+   objects, before any mapped class has been assigned to it.
+
+2. If the table contains two and exactly two :class:`.ForeignKeyConstraint`
+   objects, and all columns within this table are members of these two
+   :class:`.ForeignKeyConstraint` objects, the table is assumed to be a
+   "secondary" table, and will **not be mapped directly**.
+
+3. The two (or one, for self-referential) external tables to which the
+   :class:`.Table` refers to are matched to the classes to which they will be
+   mapped, if any.
+
+4. If mapped classes for both sides are located, a many-to-many bi-directional
+   :func:`.relationship` / :func:`.backref` pair is created between the two
+   classes.
+
+5. The override logic for many-to-many works the same as that of one-to-many/
+   many-to-one; the :func:`.generate_relationship` function is called upon
+   to generate the strucures and existing attributes will be maintained.
+
+Relationships with Inheritance
+------------------------------
+
+:mod:`.sqlalchemy.ext.automap` will not generate any relationships between
+two classes that are in an inheritance relationship.   That is, with two
+classes given as follows::
+
+    class Employee(Base):
+        __tablename__ = 'employee'
+        id = Column(Integer, primary_key=True)
+        type = Column(String(50))
+        __mapper_args__ = {
+             'polymorphic_identity':'employee', 'polymorphic_on': type
+        }
+
+    class Engineer(Employee):
+        __tablename__ = 'engineer'
+        id = Column(Integer, ForeignKey('employee.id'), primary_key=True)
+        __mapper_args__ = {
+            'polymorphic_identity':'engineer',
+        }
+
+The foreign key from ``Engineer`` to ``Employee`` is used not for a
+relationship, but to establish joined inheritance between the two classes.
+
+Note that this means automap will not generate *any* relationships
+for foreign keys that link from a subclass to a superclass.  If a mapping
+has actual relationships from subclass to superclass as well, those
+need to be explicit.  Below, as we have two separate foreign keys
+from ``Engineer`` to ``Employee``, we need to set up both the relationship
+we want as well as the ``inherit_condition``, as these are not things
+SQLAlchemy can guess::
+
+    class Employee(Base):
+        __tablename__ = 'employee'
+        id = Column(Integer, primary_key=True)
+        type = Column(String(50))
+
+        __mapper_args__ = {
+            'polymorphic_identity':'employee', 'polymorphic_on':type
+        }
+
+    class Engineer(Employee):
+        __tablename__ = 'engineer'
+        id = Column(Integer, ForeignKey('employee.id'), primary_key=True)
+        favorite_employee_id = Column(Integer, ForeignKey('employee.id'))
+
+        favorite_employee = relationship(Employee,
+                                         foreign_keys=favorite_employee_id)
+
+        __mapper_args__ = {
+            'polymorphic_identity':'engineer',
+            'inherit_condition': id == Employee.id
+        }
+
+Handling Simple Naming Conflicts
+--------------------------------
+
+In the case of naming conflicts during mapping, override any of
+:func:`.classname_for_table`, :func:`.name_for_scalar_relationship`,
+and :func:`.name_for_collection_relationship` as needed.  For example, if
+automap is attempting to name a many-to-one relationship the same as an
+existing column, an alternate convention can be conditionally selected.  Given
+a schema:
+
+.. sourcecode:: sql
+
+    CREATE TABLE table_a (
+        id INTEGER PRIMARY KEY
+    );
+
+    CREATE TABLE table_b (
+        id INTEGER PRIMARY KEY,
+        table_a INTEGER,
+        FOREIGN KEY(table_a) REFERENCES table_a(id)
+    );
+
+The above schema will first automap the ``table_a`` table as a class named
+``table_a``; it will then automap a relationship onto the class for ``table_b``
+with the same name as this related class, e.g. ``table_a``.  This
+relationship name conflicts with the mapping column ``table_b.table_a``,
+and will emit an error on mapping.
+
+We can resolve this conflict by using an underscore as follows::
+
+    def name_for_scalar_relationship(base, local_cls, referred_cls, constraint):
+        name = referred_cls.__name__.lower()
+        local_table = local_cls.__table__
+        if name in local_table.columns:
+            newname = name + "_"
+            warnings.warn(
+                "Already detected name %s present.  using %s" %
+                (name, newname))
+            return newname
+        return name
+
+
+    Base.prepare(engine, reflect=True,
+        name_for_scalar_relationship=name_for_scalar_relationship)
+
+Alternatively, we can change the name on the column side.   The columns
+that are mapped can be modified using the technique described at
+:ref:`mapper_column_distinct_names`, by assigning the column explicitly
+to a new name::
+
+    Base = automap_base()
+
+    class TableB(Base):
+        __tablename__ = 'table_b'
+        _table_a = Column('table_a', ForeignKey('table_a.id'))
+
+    Base.prepare(engine, reflect=True)
+
+
+Using Automap with Explicit Declarations
+========================================
+
+As noted previously, automap has no dependency on reflection, and can make
+use of any collection of :class:`.Table` objects within a :class:`.MetaData`
+collection.  From this, it follows that automap can also be used
+generate missing relationships given an otherwise complete model that fully
+defines table metadata::
+
+    from sqlalchemy.ext.automap import automap_base
+    from sqlalchemy import Column, Integer, String, ForeignKey
+
+    Base = automap_base()
+
+    class User(Base):
+        __tablename__ = 'user'
+
+        id = Column(Integer, primary_key=True)
+        name = Column(String)
+
+    class Address(Base):
+        __tablename__ = 'address'
+
+        id = Column(Integer, primary_key=True)
+        email = Column(String)
+        user_id = Column(ForeignKey('user.id'))
+
+    # produce relationships
+    Base.prepare()
+
+    # mapping is complete, with "address_collection" and
+    # "user" relationships
+    a1 = Address(email='u1')
+    a2 = Address(email='u2')
+    u1 = User(address_collection=[a1, a2])
+    assert a1.user is u1
+
+Above, given mostly complete ``User`` and ``Address`` mappings, the
+:class:`.ForeignKey` which we defined on ``Address.user_id`` allowed a
+bidirectional relationship pair ``Address.user`` and
+``User.address_collection`` to be generated on the mapped classes.
+
+Note that when subclassing :class:`.AutomapBase`,
+the :meth:`.AutomapBase.prepare` method is required; if not called, the classes
+we've declared are in an un-mapped state.

+"""Provides an API for creation of custom ClauseElements and compilers.
+
+Synopsis
+========
+
+Usage involves the creation of one or more
+:class:`~sqlalchemy.sql.expression.ClauseElement` subclasses and one or
+more callables defining its compilation::
+
+    from sqlalchemy.ext.compiler import compiles
+    from sqlalchemy.sql.expression import ColumnClause
+
+    class MyColumn(ColumnClause):
+        pass
+
+    @compiles(MyColumn)
+    def compile_mycolumn(element, compiler, **kw):
+        return "[%s]" % element.name
+
+Above, ``MyColumn`` extends :class:`~sqlalchemy.sql.expression.ColumnClause`,
+the base expression element for named column objects. The ``compiles``
+decorator registers itself with the ``MyColumn`` class so that it is invoked
+when the object is compiled to a string::
+
+    from sqlalchemy import select
+
+    s = select([MyColumn('x'), MyColumn('y')])
+    print str(s)
+
+Produces::
+
+    SELECT [x], [y]
+
+Dialect-specific compilation rules
+==================================
+
+Compilers can also be made dialect-specific. The appropriate compiler will be
+invoked for the dialect in use::
+
+    from sqlalchemy.schema import DDLElement
+
+    class AlterColumn(DDLElement):
+
+        def __init__(self, column, cmd):
+            self.column = column
+            self.cmd = cmd
+
+    @compiles(AlterColumn)
+    def visit_alter_column(element, compiler, **kw):
+        return "ALTER COLUMN %s ..." % element.column.name
+
+    @compiles(AlterColumn, 'postgresql')
+    def visit_alter_column(element, compiler, **kw):
+        return "ALTER TABLE %s ALTER COLUMN %s ..." % (element.table.name,
+                                                       element.column.name)
+
+The second ``visit_alter_table`` will be invoked when any ``postgresql``
+dialect is used.
+
+Compiling sub-elements of a custom expression construct
+=======================================================
+
+The ``compiler`` argument is the
+:class:`~sqlalchemy.engine.interfaces.Compiled` object in use. This object
+can be inspected for any information about the in-progress compilation,
+including ``compiler.dialect``, ``compiler.statement`` etc. The
+:class:`~sqlalchemy.sql.compiler.SQLCompiler` and
+:class:`~sqlalchemy.sql.compiler.DDLCompiler` both include a ``process()``
+method which can be used for compilation of embedded attributes::
+
+    from sqlalchemy.sql.expression import Executable, ClauseElement
+
+    class InsertFromSelect(Executable, ClauseElement):
+        def __init__(self, table, select):
+            self.table = table
+            self.select = select
+
+    @compiles(InsertFromSelect)
+    def visit_insert_from_select(element, compiler, **kw):
+        return "INSERT INTO %s (%s)" % (
+            compiler.process(element.table, asfrom=True),
+            compiler.process(element.select)
+        )
+
+    insert = InsertFromSelect(t1, select([t1]).where(t1.c.x>5))
+    print insert
+
+Produces::
+
+    "INSERT INTO mytable (SELECT mytable.x, mytable.y, mytable.z
+                          FROM mytable WHERE mytable.x > :x_1)"
+
+.. note::
+
+    The above ``InsertFromSelect`` construct is only an example, this actual
+    functionality is already available using the
+    :meth:`.Insert.from_select` method.
+
+.. note::
+
+   The above ``InsertFromSelect`` construct probably wants to have "autocommit"
+   enabled.  See :ref:`enabling_compiled_autocommit` for this step.
+
+Cross Compiling between SQL and DDL compilers
+---------------------------------------------
+
+SQL and DDL constructs are each compiled using different base compilers -
+``SQLCompiler`` and ``DDLCompiler``.   A common need is to access the
+compilation rules of SQL expressions from within a DDL expression. The
+``DDLCompiler`` includes an accessor ``sql_compiler`` for this reason, such as
+below where we generate a CHECK constraint that embeds a SQL expression::
+
+    @compiles(MyConstraint)
+    def compile_my_constraint(constraint, ddlcompiler, **kw):
+        return "CONSTRAINT %s CHECK (%s)" % (
+            constraint.name,
+            ddlcompiler.sql_compiler.process(constraint.expression)
+        )
+
+.. _enabling_compiled_autocommit:
+
+Enabling Autocommit on a Construct
+==================================
+
+Recall from the section :ref:`autocommit` that the :class:`.Engine`, when
+asked to execute a construct in the absence of a user-defined transaction,
+detects if the given construct represents DML or DDL, that is, a data
+modification or data definition statement, which requires (or may require,
+in the case of DDL) that the transaction generated by the DBAPI be committed
+(recall that DBAPI always has a transaction going on regardless of what
+SQLAlchemy does).   Checking for this is actually accomplished by checking for
+the "autocommit" execution option on the construct.    When building a
+construct like an INSERT derivation, a new DDL type, or perhaps a stored
+procedure that alters data, the "autocommit" option needs to be set in order
+for the statement to function with "connectionless" execution
+(as described in :ref:`dbengine_implicit`).
+
+Currently a quick way to do this is to subclass :class:`.Executable`, then
+add the "autocommit" flag to the ``_execution_options`` dictionary (note this
+is a "frozen" dictionary which supplies a generative ``union()`` method)::
+
+    from sqlalchemy.sql.expression import Executable, ClauseElement
+
+    class MyInsertThing(Executable, ClauseElement):
+        _execution_options = \\
+            Executable._execution_options.union({'autocommit': True})
+
+More succinctly, if the construct is truly similar to an INSERT, UPDATE, or
+DELETE, :class:`.UpdateBase` can be used, which already is a subclass
+of :class:`.Executable`, :class:`.ClauseElement` and includes the
+``autocommit`` flag::
+
+    from sqlalchemy.sql.expression import UpdateBase
+
+    class MyInsertThing(UpdateBase):
+        def __init__(self, ...):
+            ...
+
+
+
+
+DDL elements that subclass :class:`.DDLElement` already have the
+"autocommit" flag turned on.
+
+
+
+
+Changing the default compilation of existing constructs
+=======================================================
+
+The compiler extension applies just as well to the existing constructs.  When
+overriding the compilation of a built in SQL construct, the @compiles
+decorator is invoked upon the appropriate class (be sure to use the class,
+i.e. ``Insert`` or ``Select``, instead of the creation function such
+as ``insert()`` or ``select()``).
+
+Within the new compilation function, to get at the "original" compilation
+routine, use the appropriate visit_XXX method - this
+because compiler.process() will call upon the overriding routine and cause
+an endless loop.   Such as, to add "prefix" to all insert statements::
+
+    from sqlalchemy.sql.expression import Insert
+
+    @compiles(Insert)
+    def prefix_inserts(insert, compiler, **kw):
+        return compiler.visit_insert(insert.prefix_with("some prefix"), **kw)
+
+The above compiler will prefix all INSERT statements with "some prefix" when
+compiled.
+
+.. _type_compilation_extension:
+
+Changing Compilation of Types
+=============================
+
+``compiler`` works for types, too, such as below where we implement the
+MS-SQL specific 'max' keyword for ``String``/``VARCHAR``::
+
+    @compiles(String, 'mssql')
+    @compiles(VARCHAR, 'mssql')
+    def compile_varchar(element, compiler, **kw):
+        if element.length == 'max':
+            return "VARCHAR('max')"
+        else:
+            return compiler.visit_VARCHAR(element, **kw)
+
+    foo = Table('foo', metadata,
+        Column('data', VARCHAR('max'))
+    )
+
+Subclassing Guidelines
+======================
+
+A big part of using the compiler extension is subclassing SQLAlchemy
+expression constructs. To make this easier, the expression and
+schema packages feature a set of "bases" intended for common tasks.
+A synopsis is as follows:
+
+* :class:`~sqlalchemy.sql.expression.ClauseElement` - This is the root
+  expression class. Any SQL expression can be derived from this base, and is
+  probably the best choice for longer constructs such as specialized INSERT
+  statements.
+
+* :class:`~sqlalchemy.sql.expression.ColumnElement` - The root of all
+  "column-like" elements. Anything that you'd place in the "columns" clause of
+  a SELECT statement (as well as order by and group by) can derive from this -
+  the object will automatically have Python "comparison" behavior.
+
+  :class:`~sqlalchemy.sql.expression.ColumnElement` classes want to have a
+  ``type`` member which is expression's return type.  This can be established
+  at the instance level in the constructor, or at the class level if its
+  generally constant::
+
+      class timestamp(ColumnElement):
+          type = TIMESTAMP()
+
+* :class:`~sqlalchemy.sql.functions.FunctionElement` - This is a hybrid of a
+  ``ColumnElement`` and a "from clause" like object, and represents a SQL
+  function or stored procedure type of call. Since most databases support
+  statements along the line of "SELECT FROM <some function>"
+  ``FunctionElement`` adds in the ability to be used in the FROM clause of a
+  ``select()`` construct::
+
+      from sqlalchemy.sql.expression import FunctionElement
+
+      class coalesce(FunctionElement):
+          name = 'coalesce'
+
+      @compiles(coalesce)
+      def compile(element, compiler, **kw):
+          return "coalesce(%s)" % compiler.process(element.clauses)
+
+      @compiles(coalesce, 'oracle')
+      def compile(element, compiler, **kw):
+          if len(element.clauses) > 2:
+              raise TypeError("coalesce only supports two arguments on Oracle")
+          return "nvl(%s)" % compiler.process(element.clauses)
+
+* :class:`~sqlalchemy.schema.DDLElement` - The root of all DDL expressions,
+  like CREATE TABLE, ALTER TABLE, etc. Compilation of ``DDLElement``
+  subclasses is issued by a ``DDLCompiler`` instead of a ``SQLCompiler``.
+  ``DDLElement`` also features ``Table`` and ``MetaData`` event hooks via the
+  ``execute_at()`` method, allowing the construct to be invoked during CREATE
+  TABLE and DROP TABLE sequences.
+
+* :class:`~sqlalchemy.sql.expression.Executable` - This is a mixin which
+  should be used with any expression class that represents a "standalone"
+  SQL statement that can be passed directly to an ``execute()`` method.  It
+  is already implicit within ``DDLElement`` and ``FunctionElement``.
+
+Further Examples
+================
+
+"UTC timestamp" function
+-------------------------
+
+A function that works like "CURRENT_TIMESTAMP" except applies the
+appropriate conversions so that the time is in UTC time.   Timestamps are best
+stored in relational databases as UTC, without time zones.   UTC so that your
+database doesn't think time has gone backwards in the hour when daylight
+savings ends, without timezones because timezones are like character
+encodings - they're best applied only at the endpoints of an application
+(i.e. convert to UTC upon user input, re-apply desired timezone upon display).
+
+For Postgresql and Microsoft SQL Server::
+
+    from sqlalchemy.sql import expression
+    from sqlalchemy.ext.compiler import compiles
+    from sqlalchemy.types import DateTime
+
+    class utcnow(expression.FunctionElement):
+        type = DateTime()
+
+    @compiles(utcnow, 'postgresql')
+    def pg_utcnow(element, compiler, **kw):
+        return "TIMEZONE('utc', CURRENT_TIMESTAMP)"
+
+    @compiles(utcnow, 'mssql')
+    def ms_utcnow(element, compiler, **kw):
+        return "GETUTCDATE()"
+
+Example usage::
+
+    from sqlalchemy import (
+                Table, Column, Integer, String, DateTime, MetaData
+            )
+    metadata = MetaData()
+    event = Table("event", metadata,
+        Column("id", Integer, primary_key=True),
+        Column("description", String(50), nullable=False),
+        Column("timestamp", DateTime, server_default=utcnow())
+    )
+
+"GREATEST" function
+-------------------
+
+The "GREATEST" function is given any number of arguments and returns the one
+that is of the highest value - its equivalent to Python's ``max``
+function.  A SQL standard version versus a CASE based version which only
+accommodates two arguments::
+
+    from sqlalchemy.sql import expression
+    from sqlalchemy.ext.compiler import compiles
+    from sqlalchemy.types import Numeric
+
+    class greatest(expression.FunctionElement):
+        type = Numeric()
+        name = 'greatest'
+
+    @compiles(greatest)
+    def default_greatest(element, compiler, **kw):
+        return compiler.visit_function(element)
+
+    @compiles(greatest, 'sqlite')
+    @compiles(greatest, 'mssql')
+    @compiles(greatest, 'oracle')
+    def case_greatest(element, compiler, **kw):

+Synopsis
+========
+
+SQLAlchemy object-relational configuration involves the
+combination of :class:`.Table`, :func:`.mapper`, and class
+objects to define a mapped class.
+:mod:`~sqlalchemy.ext.declarative` allows all three to be
+expressed at once within the class declaration. As much as
+possible, regular SQLAlchemy schema and ORM constructs are
+used directly, so that configuration between "classical" ORM
+usage and declarative remain highly similar.
+
+As a simple example::
+
+    from sqlalchemy.ext.declarative import declarative_base
+
+    Base = declarative_base()
+
+    class SomeClass(Base):
+        __tablename__ = 'some_table'
+        id = Column(Integer, primary_key=True)
+        name =  Column(String(50))
+
+Above, the :func:`declarative_base` callable returns a new base class from
+which all mapped classes should inherit. When the class definition is
+completed, a new :class:`.Table` and :func:`.mapper` will have been generated.
+
+The resulting table and mapper are accessible via
+``__table__`` and ``__mapper__`` attributes on the
+``SomeClass`` class::
+
+    # access the mapped Table
+    SomeClass.__table__
+
+    # access the Mapper
+    SomeClass.__mapper__
+
+Defining Attributes
+===================
+
+In the previous example, the :class:`.Column` objects are
+automatically named with the name of the attribute to which they are
+assigned.
+
+To name columns explicitly with a name distinct from their mapped attribute,
+just give the column a name.  Below, column "some_table_id" is mapped to the
+"id" attribute of `SomeClass`, but in SQL will be represented as
+"some_table_id"::
+
+    class SomeClass(Base):
+        __tablename__ = 'some_table'
+        id = Column("some_table_id", Integer, primary_key=True)
+
+Attributes may be added to the class after its construction, and they will be
+added to the underlying :class:`.Table` and
+:func:`.mapper` definitions as appropriate::
+
+    SomeClass.data = Column('data', Unicode)
+    SomeClass.related = relationship(RelatedInfo)
+
+Classes which are constructed using declarative can interact freely
+with classes that are mapped explicitly with :func:`.mapper`.
+
+It is recommended, though not required, that all tables
+share the same underlying :class:`~sqlalchemy.schema.MetaData` object,
+so that string-configured :class:`~sqlalchemy.schema.ForeignKey`
+references can be resolved without issue.
+
+Accessing the MetaData
+=======================
+
+The :func:`declarative_base` base class contains a
+:class:`.MetaData` object where newly defined
+:class:`.Table` objects are collected. This object is
+intended to be accessed directly for
+:class:`.MetaData`-specific operations. Such as, to issue
+CREATE statements for all tables::
+
+    engine = create_engine('sqlite://')
+    Base.metadata.create_all(engine)
+
+:func:`declarative_base` can also receive a pre-existing
+:class:`.MetaData` object, which allows a
+declarative setup to be associated with an already
+existing traditional collection of :class:`~sqlalchemy.schema.Table`
+objects::
+
+    mymetadata = MetaData()
+    Base = declarative_base(metadata=mymetadata)
+
+
+.. _declarative_configuring_relationships:
+
+Configuring Relationships
+=========================
+
+Relationships to other classes are done in the usual way, with the added
+feature that the class specified to :func:`~sqlalchemy.orm.relationship`
+may be a string name.  The "class registry" associated with ``Base``
+is used at mapper compilation time to resolve the name into the actual
+class object, which is expected to have been defined once the mapper
+configuration is used::
+
+    class User(Base):
+        __tablename__ = 'users'
+
+        id = Column(Integer, primary_key=True)
+        name = Column(String(50))
+        addresses = relationship("Address", backref="user")
+
+    class Address(Base):
+        __tablename__ = 'addresses'
+
+        id = Column(Integer, primary_key=True)
+        email = Column(String(50))
+        user_id = Column(Integer, ForeignKey('users.id'))
+
+Column constructs, since they are just that, are immediately usable,
+as below where we define a primary join condition on the ``Address``
+class using them::
+
+    class Address(Base):
+        __tablename__ = 'addresses'
+
+        id = Column(Integer, primary_key=True)
+        email = Column(String(50))
+        user_id = Column(Integer, ForeignKey('users.id'))
+        user = relationship(User, primaryjoin=user_id == User.id)
+
+In addition to the main argument for :func:`~sqlalchemy.orm.relationship`,
+other arguments which depend upon the columns present on an as-yet
+undefined class may also be specified as strings.  These strings are
+evaluated as Python expressions.  The full namespace available within
+this evaluation includes all classes mapped for this declarative base,
+as well as the contents of the ``sqlalchemy`` package, including
+expression functions like :func:`~sqlalchemy.sql.expression.desc` and
+:attr:`~sqlalchemy.sql.expression.func`::
+
+    class User(Base):
+        # ....
+        addresses = relationship("Address",
+                             order_by="desc(Address.email)",
+                             primaryjoin="Address.user_id==User.id")
+
+For the case where more than one module contains a class of the same name,
+string class names can also be specified as module-qualified paths
+within any of these string expressions::
+
+    class User(Base):
+        # ....
+        addresses = relationship("myapp.model.address.Address",
+                             order_by="desc(myapp.model.address.Address.email)",
+                             primaryjoin="myapp.model.address.Address.user_id=="
+                                            "myapp.model.user.User.id")
+
+The qualified path can be any partial path that removes ambiguity between
+the names.  For example, to disambiguate between
+``myapp.model.address.Address`` and ``myapp.model.lookup.Address``,
+we can specify ``address.Address`` or ``lookup.Address``::
+
+    class User(Base):
+        # ....
+        addresses = relationship("address.Address",
+                             order_by="desc(address.Address.email)",
+                             primaryjoin="address.Address.user_id=="
+                                            "User.id")
+
+.. versionadded:: 0.8
+   module-qualified paths can be used when specifying string arguments
+   with Declarative, in order to specify specific modules.
+
+Two alternatives also exist to using string-based attributes.  A lambda
+can also be used, which will be evaluated after all mappers have been
+configured::
+
+    class User(Base):
+        # ...
+        addresses = relationship(lambda: Address,
+                             order_by=lambda: desc(Address.email),
+                             primaryjoin=lambda: Address.user_id==User.id)
+
+Or, the relationship can be added to the class explicitly after the classes
+are available::
+
+    User.addresses = relationship(Address,
+                              primaryjoin=Address.user_id==User.id)
+
+
+
+.. _declarative_many_to_many:
+
+Configuring Many-to-Many Relationships
+======================================
+
+Many-to-many relationships are also declared in the same way
+with declarative as with traditional mappings. The
+``secondary`` argument to
+:func:`.relationship` is as usual passed a
+:class:`.Table` object, which is typically declared in the
+traditional way.  The :class:`.Table` usually shares
+the :class:`.MetaData` object used by the declarative base::
+
+    keywords = Table(
+        'keywords', Base.metadata,
+        Column('author_id', Integer, ForeignKey('authors.id')),
+        Column('keyword_id', Integer, ForeignKey('keywords.id'))
+        )
+
+    class Author(Base):
+        __tablename__ = 'authors'
+        id = Column(Integer, primary_key=True)
+        keywords = relationship("Keyword", secondary=keywords)
+
+Like other :func:`~sqlalchemy.orm.relationship` arguments, a string is accepted
+as well, passing the string name of the table as defined in the
+``Base.metadata.tables`` collection::
+
+    class Author(Base):
+        __tablename__ = 'authors'
+        id = Column(Integer, primary_key=True)
+        keywords = relationship("Keyword", secondary="keywords")
+
+As with traditional mapping, its generally not a good idea to use
+a :class:`.Table` as the "secondary" argument which is also mapped to
+a class, unless the :func:`.relationship` is declared with ``viewonly=True``.
+Otherwise, the unit-of-work system may attempt duplicate INSERT and
+DELETE statements against the underlying table.
+
+.. _declarative_sql_expressions:
+
+Defining SQL Expressions
+========================
+
+See :ref:`mapper_sql_expressions` for examples on declaratively
+mapping attributes to SQL expressions.
+
+.. _declarative_table_args:
+
+Table Configuration
+===================
+
+Table arguments other than the name, metadata, and mapped Column
+arguments are specified using the ``__table_args__`` class attribute.
+This attribute accommodates both positional as well as keyword
+arguments that are normally sent to the
+:class:`~sqlalchemy.schema.Table` constructor.
+The attribute can be specified in one of two forms. One is as a
+dictionary::
+
+    class MyClass(Base):
+        __tablename__ = 'sometable'
+        __table_args__ = {'mysql_engine':'InnoDB'}
+
+The other, a tuple, where each argument is positional
+(usually constraints)::
+
+    class MyClass(Base):
+        __tablename__ = 'sometable'
+        __table_args__ = (
+                ForeignKeyConstraint(['id'], ['remote_table.id']),
+                UniqueConstraint('foo'),
+                )
+
+Keyword arguments can be specified with the above form by
+specifying the last argument as a dictionary::
+
+    class MyClass(Base):
+        __tablename__ = 'sometable'
+        __table_args__ = (
+                ForeignKeyConstraint(['id'], ['remote_table.id']),
+                UniqueConstraint('foo'),
+                {'autoload':True}
+                )
+
+Using a Hybrid Approach with __table__
+=======================================
+
+As an alternative to ``__tablename__``, a direct
+:class:`~sqlalchemy.schema.Table` construct may be used.  The
+:class:`~sqlalchemy.schema.Column` objects, which in this case require
+their names, will be added to the mapping just like a regular mapping
+to a table::
+
+    class MyClass(Base):
+        __table__ = Table('my_table', Base.metadata,
+            Column('id', Integer, primary_key=True),
+            Column('name', String(50))
+        )
+
+``__table__`` provides a more focused point of control for establishing
+table metadata, while still getting most of the benefits of using declarative.
+An application that uses reflection might want to load table metadata elsewhere
+and pass it to declarative classes::
+
+    from sqlalchemy.ext.declarative import declarative_base
+
+    Base = declarative_base()
+    Base.metadata.reflect(some_engine)
+
+    class User(Base):
+        __table__ = metadata.tables['user']
+
+    class Address(Base):
+        __table__ = metadata.tables['address']
+
+Some configuration schemes may find it more appropriate to use ``__table__``,
+such as those which already take advantage of the data-driven nature of
+:class:`.Table` to customize and/or automate schema definition.
+
+Note that when the ``__table__`` approach is used, the object is immediately
+usable as a plain :class:`.Table` within the class declaration body itself,
+as a Python class is only another syntactical block.  Below this is illustrated
+by using the ``id`` column in the ``primaryjoin`` condition of a
+:func:`.relationship`::
+
+    class MyClass(Base):
+        __table__ = Table('my_table', Base.metadata,
+            Column('id', Integer, primary_key=True),
+            Column('name', String(50))
+        )
+
+        widgets = relationship(Widget,
+                    primaryjoin=Widget.myclass_id==__table__.c.id)
+
+Similarly, mapped attributes which refer to ``__table__`` can be placed inline,
+as below where we assign the ``name`` column to the attribute ``_name``,
+generating a synonym for ``name``::
+
+    from sqlalchemy.ext.declarative import synonym_for
+
+    class MyClass(Base):
+        __table__ = Table('my_table', Base.metadata,
+            Column('id', Integer, primary_key=True),
+            Column('name', String(50))
+        )
+
+        _name = __table__.c.name
+
+        @synonym_for("_name")
+        def name(self):
+            return "Name: %s" % _name
+
+Using Reflection with Declarative
+=================================
+
+It's easy to set up a :class:`.Table` that uses ``autoload=True``
+in conjunction with a mapped class::
+
+    class MyClass(Base):
+        __table__ = Table('mytable', Base.metadata,
+                        autoload=True, autoload_with=some_engine)
+
+However, one improvement that can be made here is to not
+require the :class:`.Engine` to be available when classes are
+being first declared.   To achieve this, use the
+:class:`.DeferredReflection` mixin, which sets up mappings
+only after a special ``prepare(engine)`` step is called::
+
+    from sqlalchemy.ext.declarative import declarative_base, DeferredReflection
+
+    Base = declarative_base(cls=DeferredReflection)
+
+    class Foo(Base):
+        __tablename__ = 'foo'
+        bars = relationship("Bar")
+
+    class Bar(Base):
+        __tablename__ = 'bar'
+
+        # illustrate overriding of "bar.foo_id" to have
+        # a foreign key constraint otherwise not
+        # reflected, such as when using MySQL
+        foo_id = Column(Integer, ForeignKey('foo.id'))
+
+    Base.prepare(e)
+
+.. versionadded:: 0.8
+   Added :class:`.DeferredReflection`.
+
+Mapper Configuration
+====================
+
+Declarative makes use of the :func:`~.orm.mapper` function internally
+when it creates the mapping to the declared table.   The options
+for :func:`~.orm.mapper` are passed directly through via the
+``__mapper_args__`` class attribute.  As always, arguments which reference
+locally mapped columns can reference them directly from within the
+class declaration::
+
+    from datetime import datetime
+
+    class Widget(Base):
+        __tablename__ = 'widgets'
+
+        id = Column(Integer, primary_key=True)
+        timestamp = Column(DateTime, nullable=False)
+
+        __mapper_args__ = {
+                        'version_id_col': timestamp,
+                        'version_id_generator': lambda v:datetime.now()
+                    }
+
+.. _declarative_inheritance:
+
+Inheritance Configuration
+=========================
+
+Declarative supports all three forms of inheritance as intuitively
+as possible.  The ``inherits`` mapper keyword argument is not needed
+as declarative will determine this from the class itself.   The various
+"polymorphic" keyword arguments are specified using ``__mapper_args__``.
+
+Joined Table Inheritance
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Joined table inheritance is defined as a subclass that defines its own
+table::
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        __tablename__ = 'engineers'
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+        id = Column(Integer, ForeignKey('people.id'), primary_key=True)
+        primary_language = Column(String(50))
+
+Note that above, the ``Engineer.id`` attribute, since it shares the
+same attribute name as the ``Person.id`` attribute, will in fact
+represent the ``people.id`` and ``engineers.id`` columns together,
+with the "Engineer.id" column taking precedence if queried directly.
+To provide the ``Engineer`` class with an attribute that represents
+only the ``engineers.id`` column, give it a different attribute name::
+
+    class Engineer(Person):
+        __tablename__ = 'engineers'
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+        engineer_id = Column('id', Integer, ForeignKey('people.id'),
+                                                    primary_key=True)
+        primary_language = Column(String(50))
+
+
+.. versionchanged:: 0.7 joined table inheritance favors the subclass
+   column over that of the superclass, such as querying above
+   for ``Engineer.id``.  Prior to 0.7 this was the reverse.
+
+.. _declarative_single_table:
+
+Single Table Inheritance
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Single table inheritance is defined as a subclass that does not have
+its own table; you just leave out the ``__table__`` and ``__tablename__``
+attributes::
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+        primary_language = Column(String(50))
+
+When the above mappers are configured, the ``Person`` class is mapped
+to the ``people`` table *before* the ``primary_language`` column is
+defined, and this column will not be included in its own mapping.
+When ``Engineer`` then defines the ``primary_language`` column, the
+column is added to the ``people`` table so that it is included in the
+mapping for ``Engineer`` and is also part of the table's full set of
+columns.  Columns which are not mapped to ``Person`` are also excluded
+from any other single or joined inheriting classes using the
+``exclude_properties`` mapper argument.  Below, ``Manager`` will have
+all the attributes of ``Person`` and ``Manager`` but *not* the
+``primary_language`` attribute of ``Engineer``::
+
+    class Manager(Person):
+        __mapper_args__ = {'polymorphic_identity': 'manager'}
+        golf_swing = Column(String(50))
+
+The attribute exclusion logic is provided by the
+``exclude_properties`` mapper argument, and declarative's default
+behavior can be disabled by passing an explicit ``exclude_properties``
+collection (empty or otherwise) to the ``__mapper_args__``.
+
+Resolving Column Conflicts
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Note above that the ``primary_language`` and ``golf_swing`` columns
+are "moved up" to be applied to ``Person.__table__``, as a result of their
+declaration on a subclass that has no table of its own.   A tricky case
+comes up when two subclasses want to specify *the same* column, as below::
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+        start_date = Column(DateTime)
+
+    class Manager(Person):
+        __mapper_args__ = {'polymorphic_identity': 'manager'}
+        start_date = Column(DateTime)
+
+Above, the ``start_date`` column declared on both ``Engineer`` and ``Manager``
+will result in an error::
+
+    sqlalchemy.exc.ArgumentError: Column 'start_date' on class
+    <class '__main__.Manager'> conflicts with existing
+    column 'people.start_date'
+
+In a situation like this, Declarative can't be sure
+of the intent, especially if the ``start_date`` columns had, for example,
+different types.   A situation like this can be resolved by using
+:class:`.declared_attr` to define the :class:`.Column` conditionally, taking
+care to return the **existing column** via the parent ``__table__`` if it
+already exists::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+
+        @declared_attr
+        def start_date(cls):
+            "Start date column, if not present already."
+            return Person.__table__.c.get('start_date', Column(DateTime))
+
+    class Manager(Person):
+        __mapper_args__ = {'polymorphic_identity': 'manager'}
+
+        @declared_attr
+        def start_date(cls):
+            "Start date column, if not present already."
+            return Person.__table__.c.get('start_date', Column(DateTime))
+
+Above, when ``Manager`` is mapped, the ``start_date`` column is
+already present on the ``Person`` class.  Declarative lets us return
+that :class:`.Column` as a result in this case, where it knows to skip
+re-assigning the same column. If the mapping is mis-configured such
+that the ``start_date`` column is accidentally re-assigned to a
+different table (such as, if we changed ``Manager`` to be joined
+inheritance without fixing ``start_date``), an error is raised which
+indicates an existing :class:`.Column` is trying to be re-assigned to
+a different owning :class:`.Table`.
+
+.. versionadded:: 0.8 :class:`.declared_attr` can be used on a non-mixin
+   class, and the returned :class:`.Column` or other mapped attribute
+   will be applied to the mapping as any other attribute.  Previously,
+   the resulting attribute would be ignored, and also result in a warning
+   being emitted when a subclass was created.
+
+.. versionadded:: 0.8 :class:`.declared_attr`, when used either with a
+   mixin or non-mixin declarative class, can return an existing
+   :class:`.Column` already assigned to the parent :class:`.Table`,
+   to indicate that the re-assignment of the :class:`.Column` should be
+   skipped, however should still be mapped on the target class,
+   in order to resolve duplicate column conflicts.
+
+The same concept can be used with mixin classes (see
+:ref:`declarative_mixins`)::
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class HasStartDate(object):
+        @declared_attr
+        def start_date(cls):
+            return cls.__table__.c.get('start_date', Column(DateTime))
+
+    class Engineer(HasStartDate, Person):
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+
+    class Manager(HasStartDate, Person):
+        __mapper_args__ = {'polymorphic_identity': 'manager'}
+
+The above mixin checks the local ``__table__`` attribute for the column.
+Because we're using single table inheritance, we're sure that in this case,
+``cls.__table__`` refers to ``People.__table__``.  If we were mixing joined-
+and single-table inheritance, we might want our mixin to check more carefully
+if ``cls.__table__`` is really the :class:`.Table` we're looking for.
+
+Concrete Table Inheritance
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Concrete is defined as a subclass which has its own table and sets the
+``concrete`` keyword argument to ``True``::
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        name = Column(String(50))
+
+    class Engineer(Person):
+        __tablename__ = 'engineers'
+        __mapper_args__ = {'concrete':True}
+        id = Column(Integer, primary_key=True)
+        primary_language = Column(String(50))
+        name = Column(String(50))
+
+Usage of an abstract base class is a little less straightforward as it
+requires usage of :func:`~sqlalchemy.orm.util.polymorphic_union`,
+which needs to be created with the :class:`.Table` objects
+before the class is built::
+
+    engineers = Table('engineers', Base.metadata,
+                    Column('id', Integer, primary_key=True),
+                    Column('name', String(50)),
+                    Column('primary_language', String(50))
+                )
+    managers = Table('managers', Base.metadata,
+                    Column('id', Integer, primary_key=True),
+                    Column('name', String(50)),
+                    Column('golf_swing', String(50))
+                )
+
+    punion = polymorphic_union({
+        'engineer':engineers,
+        'manager':managers
+    }, 'type', 'punion')
+
+    class Person(Base):
+        __table__ = punion
+        __mapper_args__ = {'polymorphic_on':punion.c.type}
+
+    class Engineer(Person):
+        __table__ = engineers
+        __mapper_args__ = {'polymorphic_identity':'engineer', 'concrete':True}
+
+    class Manager(Person):
+        __table__ = managers
+        __mapper_args__ = {'polymorphic_identity':'manager', 'concrete':True}
+
+.. _declarative_concrete_helpers:
+
+Using the Concrete Helpers
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Helper classes provides a simpler pattern for concrete inheritance.
+With these objects, the ``__declare_first__`` helper is used to configure the
+"polymorphic" loader for the mapper after all subclasses have been declared.
+
+.. versionadded:: 0.7.3
+
+An abstract base can be declared using the
+:class:`.AbstractConcreteBase` class::
+
+    from sqlalchemy.ext.declarative import AbstractConcreteBase
+
+    class Employee(AbstractConcreteBase, Base):
+        pass
+
+To have a concrete ``employee`` table, use :class:`.ConcreteBase` instead::
+
+    from sqlalchemy.ext.declarative import ConcreteBase
+
+    class Employee(ConcreteBase, Base):
+        __tablename__ = 'employee'
+        employee_id = Column(Integer, primary_key=True)
+        name = Column(String(50))
+        __mapper_args__ = {
+                        'polymorphic_identity':'employee',
+                        'concrete':True}
+
+
+Either ``Employee`` base can be used in the normal fashion::
+
+    class Manager(Employee):
+        __tablename__ = 'manager'
+        employee_id = Column(Integer, primary_key=True)
+        name = Column(String(50))
+        manager_data = Column(String(40))
+        __mapper_args__ = {
+                        'polymorphic_identity':'manager',
+                        'concrete':True}
+
+    class Engineer(Employee):
+        __tablename__ = 'engineer'
+        employee_id = Column(Integer, primary_key=True)
+        name = Column(String(50))
+        engineer_info = Column(String(40))
+        __mapper_args__ = {'polymorphic_identity':'engineer',
+                        'concrete':True}
+
+
+The :class:`.AbstractConcreteBase` class is itself mapped, and can be
+used as a target of relationships::
+
+    class Company(Base):
+        __tablename__ = 'company'
+
+        id = Column(Integer, primary_key=True)
+        employees = relationship("Employee",
+                        primaryjoin="Company.id == Employee.company_id")
+
+
+.. versionchanged:: 0.9.3 Support for use of :class:`.AbstractConcreteBase`
+   as the target of a :func:`.relationship` has been improved.
+
+It can also be queried directly::
+
+    for employee in session.query(Employee).filter(Employee.name == 'qbert'):
+        print(employee)
+
+
+.. _declarative_mixins:
+
+Mixin and Custom Base Classes
+==============================
+
+A common need when using :mod:`~sqlalchemy.ext.declarative` is to
+share some functionality, such as a set of common columns, some common
+table options, or other mapped properties, across many
+classes.  The standard Python idioms for this is to have the classes
+inherit from a base which includes these common features.
+
+When using :mod:`~sqlalchemy.ext.declarative`, this idiom is allowed
+via the usage of a custom declarative base class, as well as a "mixin" class
+which is inherited from in addition to the primary base.  Declarative
+includes several helper features to make this work in terms of how
+mappings are declared.   An example of some commonly mixed-in
+idioms is below::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class MyMixin(object):
+
+        @declared_attr
+        def __tablename__(cls):
+            return cls.__name__.lower()
+
+        __table_args__ = {'mysql_engine': 'InnoDB'}
+        __mapper_args__= {'always_refresh': True}
+
+        id =  Column(Integer, primary_key=True)
+
+    class MyModel(MyMixin, Base):
+        name = Column(String(1000))
+
+Where above, the class ``MyModel`` will contain an "id" column
+as the primary key, a ``__tablename__`` attribute that derives
+from the name of the class itself, as well as ``__table_args__``
+and ``__mapper_args__`` defined by the ``MyMixin`` mixin class.
+
+There's no fixed convention over whether ``MyMixin`` precedes
+``Base`` or not.  Normal Python method resolution rules apply, and
+the above example would work just as well with::
+
+    class MyModel(Base, MyMixin):
+        name = Column(String(1000))
+
+This works because ``Base`` here doesn't define any of the
+variables that ``MyMixin`` defines, i.e. ``__tablename__``,
+``__table_args__``, ``id``, etc.   If the ``Base`` did define
+an attribute of the same name, the class placed first in the
+inherits list would determine which attribute is used on the
+newly defined class.
+
+Augmenting the Base
+~~~~~~~~~~~~~~~~~~~
+
+In addition to using a pure mixin, most of the techniques in this
+section can also be applied to the base class itself, for patterns that
+should apply to all classes derived from a particular base.  This is achieved
+using the ``cls`` argument of the :func:`.declarative_base` function::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class Base(object):
+        @declared_attr
+        def __tablename__(cls):
+            return cls.__name__.lower()
+
+        __table_args__ = {'mysql_engine': 'InnoDB'}
+
+        id =  Column(Integer, primary_key=True)
+
+    from sqlalchemy.ext.declarative import declarative_base
+
+    Base = declarative_base(cls=Base)
+
+    class MyModel(Base):
+        name = Column(String(1000))
+
+Where above, ``MyModel`` and all other classes that derive from ``Base`` will
+have a table name derived from the class name, an ``id`` primary key column,
+as well as the "InnoDB" engine for MySQL.
+
+Mixing in Columns
+~~~~~~~~~~~~~~~~~
+
+The most basic way to specify a column on a mixin is by simple
+declaration::
+
+    class TimestampMixin(object):
+        created_at = Column(DateTime, default=func.now())
+
+    class MyModel(TimestampMixin, Base):
+        __tablename__ = 'test'
+
+        id =  Column(Integer, primary_key=True)
+        name = Column(String(1000))
+
+Where above, all declarative classes that include ``TimestampMixin``
+will also have a column ``created_at`` that applies a timestamp to
+all row insertions.
+
+Those familiar with the SQLAlchemy expression language know that
+the object identity of clause elements defines their role in a schema.
+Two ``Table`` objects ``a`` and ``b`` may both have a column called
+``id``, but the way these are differentiated is that ``a.c.id``
+and ``b.c.id`` are two distinct Python objects, referencing their
+parent tables ``a`` and ``b`` respectively.
+
+In the case of the mixin column, it seems that only one
+:class:`.Column` object is explicitly created, yet the ultimate
+``created_at`` column above must exist as a distinct Python object
+for each separate destination class.  To accomplish this, the declarative
+extension creates a **copy** of each :class:`.Column` object encountered on
+a class that is detected as a mixin.
+
+This copy mechanism is limited to simple columns that have no foreign
+keys, as a :class:`.ForeignKey` itself contains references to columns
+which can't be properly recreated at this level.  For columns that
+have foreign keys, as well as for the variety of mapper-level constructs
+that require destination-explicit context, the
+:class:`~.declared_attr` decorator is provided so that
+patterns common to many classes can be defined as callables::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class ReferenceAddressMixin(object):
+        @declared_attr
+        def address_id(cls):
+            return Column(Integer, ForeignKey('address.id'))
+
+    class User(ReferenceAddressMixin, Base):
+        __tablename__ = 'user'
+        id = Column(Integer, primary_key=True)
+
+Where above, the ``address_id`` class-level callable is executed at the
+point at which the ``User`` class is constructed, and the declarative
+extension can use the resulting :class:`.Column` object as returned by
+the method without the need to copy it.
+
+.. versionchanged:: > 0.6.5
+    Rename 0.6.5 ``sqlalchemy.util.classproperty``
+    into :class:`~.declared_attr`.
+
+Columns generated by :class:`~.declared_attr` can also be
+referenced by ``__mapper_args__`` to a limited degree, currently
+by ``polymorphic_on`` and ``version_id_col``, by specifying the
+classdecorator itself into the dictionary - the declarative extension
+will resolve them at class construction time::
+
+    class MyMixin:
+        @declared_attr
+        def type_(cls):
+            return Column(String(50))
+
+        __mapper_args__= {'polymorphic_on':type_}
+
+    class MyModel(MyMixin, Base):
+        __tablename__='test'
+        id =  Column(Integer, primary_key=True)
+
+
+
+Mixing in Relationships
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Relationships created by :func:`~sqlalchemy.orm.relationship` are provided
+with declarative mixin classes exclusively using the
+:class:`.declared_attr` approach, eliminating any ambiguity
+which could arise when copying a relationship and its possibly column-bound
+contents. Below is an example which combines a foreign key column and a
+relationship so that two classes ``Foo`` and ``Bar`` can both be configured to
+reference a common target class via many-to-one::
+
+    class RefTargetMixin(object):
+        @declared_attr
+        def target_id(cls):
+            return Column('target_id', ForeignKey('target.id'))
+
+        @declared_attr
+        def target(cls):
+            return relationship("Target")
+
+    class Foo(RefTargetMixin, Base):
+        __tablename__ = 'foo'
+        id = Column(Integer, primary_key=True)
+
+    class Bar(RefTargetMixin, Base):
+        __tablename__ = 'bar'
+        id = Column(Integer, primary_key=True)
+
+    class Target(Base):
+        __tablename__ = 'target'
+        id = Column(Integer, primary_key=True)
+
+Using Advanced Relationship Arguments (e.g. ``primaryjoin``, etc.)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+:func:`~sqlalchemy.orm.relationship` definitions which require explicit
+primaryjoin, order_by etc. expressions should in all but the most
+simplistic cases use **late bound** forms
+for these arguments, meaning, using either the string form or a lambda.
+The reason for this is that the related :class:`.Column` objects which are to
+be configured using ``@declared_attr`` are not available to another
+``@declared_attr`` attribute; while the methods will work and return new
+:class:`.Column` objects, those are not the :class:`.Column` objects that
+Declarative will be using as it calls the methods on its own, thus using
+*different* :class:`.Column` objects.
+
+The canonical example is the primaryjoin condition that depends upon
+another mixed-in column::
+
+    class RefTargetMixin(object):
+        @declared_attr
+        def target_id(cls):
+            return Column('target_id', ForeignKey('target.id'))
+
+        @declared_attr
+        def target(cls):
+            return relationship(Target,
+                primaryjoin=Target.id==cls.target_id   # this is *incorrect*
+            )
+
+Mapping a class using the above mixin, we will get an error like::
+
+    sqlalchemy.exc.InvalidRequestError: this ForeignKey's parent column is not
+    yet associated with a Table.
+
+This is because the ``target_id`` :class:`.Column` we've called upon in our
+``target()`` method is not the same :class:`.Column` that declarative is
+actually going to map to our table.
+
+The condition above is resolved using a lambda::
+
+    class RefTargetMixin(object):
+        @declared_attr
+        def target_id(cls):
+            return Column('target_id', ForeignKey('target.id'))
+
+        @declared_attr
+        def target(cls):
+            return relationship(Target,
+                primaryjoin=lambda: Target.id==cls.target_id
+            )
+
+or alternatively, the string form (which ultimately generates a lambda)::
+
+    class RefTargetMixin(object):
+        @declared_attr
+        def target_id(cls):
+            return Column('target_id', ForeignKey('target.id'))
+
+        @declared_attr
+        def target(cls):
+            return relationship("Target",
+                primaryjoin="Target.id==%s.target_id" % cls.__name__
+            )
+
+Mixing in deferred(), column_property(), and other MapperProperty classes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Like :func:`~sqlalchemy.orm.relationship`, all
+:class:`~sqlalchemy.orm.interfaces.MapperProperty` subclasses such as
+:func:`~sqlalchemy.orm.deferred`, :func:`~sqlalchemy.orm.column_property`,
+etc. ultimately involve references to columns, and therefore, when
+used with declarative mixins, have the :class:`.declared_attr`
+requirement so that no reliance on copying is needed::
+
+    class SomethingMixin(object):
+
+        @declared_attr
+        def dprop(cls):
+            return deferred(Column(Integer))
+
+    class Something(SomethingMixin, Base):
+        __tablename__ = "something"
+
+Mixing in Association Proxy and Other Attributes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Mixins can specify user-defined attributes as well as other extension
+units such as :func:`.association_proxy`.   The usage of
+:class:`.declared_attr` is required in those cases where the attribute must
+be tailored specifically to the target subclass.   An example is when
+constructing multiple :func:`.association_proxy` attributes which each
+target a different type of child object.  Below is an
+:func:`.association_proxy` / mixin example which provides a scalar list of
+string values to an implementing class::
+
+    from sqlalchemy import Column, Integer, ForeignKey, String
+    from sqlalchemy.orm import relationship
+    from sqlalchemy.ext.associationproxy import association_proxy
+    from sqlalchemy.ext.declarative import declarative_base, declared_attr
+
+    Base = declarative_base()
+
+    class HasStringCollection(object):
+        @declared_attr
+        def _strings(cls):
+            class StringAttribute(Base):
+                __tablename__ = cls.string_table_name
+                id = Column(Integer, primary_key=True)
+                value = Column(String(50), nullable=False)
+                parent_id = Column(Integer,
+                                ForeignKey('%s.id' % cls.__tablename__),
+                                nullable=False)
+                def __init__(self, value):
+                    self.value = value
+
+            return relationship(StringAttribute)
+
+        @declared_attr
+        def strings(cls):
+            return association_proxy('_strings', 'value')
+
+    class TypeA(HasStringCollection, Base):
+        __tablename__ = 'type_a'
+        string_table_name = 'type_a_strings'
+        id = Column(Integer(), primary_key=True)
+
+    class TypeB(HasStringCollection, Base):
+        __tablename__ = 'type_b'
+        string_table_name = 'type_b_strings'
+        id = Column(Integer(), primary_key=True)
+
+Above, the ``HasStringCollection`` mixin produces a :func:`.relationship`
+which refers to a newly generated class called ``StringAttribute``.  The
+``StringAttribute`` class is generated with its own :class:`.Table`
+definition which is local to the parent class making usage of the
+``HasStringCollection`` mixin.  It also produces an :func:`.association_proxy`
+object which proxies references to the ``strings`` attribute onto the ``value``
+attribute of each ``StringAttribute`` instance.
+
+``TypeA`` or ``TypeB`` can be instantiated given the constructor
+argument ``strings``, a list of strings::
+
+    ta = TypeA(strings=['foo', 'bar'])
+    tb = TypeA(strings=['bat', 'bar'])
+
+This list will generate a collection
+of ``StringAttribute`` objects, which are persisted into a table that's
+local to either the ``type_a_strings`` or ``type_b_strings`` table::
+
+    >>> print ta._strings
+    [<__main__.StringAttribute object at 0x10151cd90>,
+        <__main__.StringAttribute object at 0x10151ce10>]
+
+When constructing the :func:`.association_proxy`, the
+:class:`.declared_attr` decorator must be used so that a distinct
+:func:`.association_proxy` object is created for each of the ``TypeA``
+and ``TypeB`` classes.
+
+.. versionadded:: 0.8 :class:`.declared_attr` is usable with non-mapped
+   attributes, including user-defined attributes as well as
+   :func:`.association_proxy`.
+
+
+Controlling table inheritance with mixins
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``__tablename__`` attribute in conjunction with the hierarchy of
+classes involved in a declarative mixin scenario controls what type of
+table inheritance, if any,
+is configured by the declarative extension.
+
+If the ``__tablename__`` is computed by a mixin, you may need to
+control which classes get the computed attribute in order to get the
+type of table inheritance you require.
+
+For example, if you had a mixin that computes ``__tablename__`` but
+where you wanted to use that mixin in a single table inheritance
+hierarchy, you can explicitly specify ``__tablename__`` as ``None`` to
+indicate that the class should not have a table mapped::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class Tablename:
+        @declared_attr
+        def __tablename__(cls):
+            return cls.__name__.lower()
+
+    class Person(Tablename, Base):
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        __tablename__ = None
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+        primary_language = Column(String(50))
+
+Alternatively, you can make the mixin intelligent enough to only
+return a ``__tablename__`` in the event that no table is already
+mapped in the inheritance hierarchy. To help with this, a
+:func:`~sqlalchemy.ext.declarative.has_inherited_table` helper
+function is provided that returns ``True`` if a parent class already
+has a mapped table.
+
+As an example, here's a mixin that will only allow single table
+inheritance::
+
+    from sqlalchemy.ext.declarative import declared_attr
+    from sqlalchemy.ext.declarative import has_inherited_table
+
+    class Tablename(object):
+        @declared_attr
+        def __tablename__(cls):
+            if has_inherited_table(cls):
+                return None
+            return cls.__name__.lower()
+
+    class Person(Tablename, Base):
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        primary_language = Column(String(50))
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+
+
+Combining Table/Mapper Arguments from Multiple Mixins
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In the case of ``__table_args__`` or ``__mapper_args__``
+specified with declarative mixins, you may want to combine
+some parameters from several mixins with those you wish to
+define on the class iteself. The
+:class:`.declared_attr` decorator can be used
+here to create user-defined collation routines that pull
+from multiple collections::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class MySQLSettings(object):
+        __table_args__ = {'mysql_engine':'InnoDB'}
+
+    class MyOtherMixin(object):
+        __table_args__ = {'info':'foo'}
+
+    class MyModel(MySQLSettings, MyOtherMixin, Base):
+        __tablename__='my_model'
+
+        @declared_attr
+        def __table_args__(cls):
+            args = dict()
+            args.update(MySQLSettings.__table_args__)
+            args.update(MyOtherMixin.__table_args__)
+            return args
+
+        id =  Column(Integer, primary_key=True)
+
+Creating Indexes with Mixins
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To define a named, potentially multicolumn :class:`.Index` that applies to all
+tables derived from a mixin, use the "inline" form of :class:`.Index` and
+establish it as part of ``__table_args__``::
+
+    class MyMixin(object):
+        a =  Column(Integer)
+        b =  Column(Integer)
+
+        @declared_attr
+        def __table_args__(cls):
+            return (Index('test_idx_%s' % cls.__tablename__, 'a', 'b'),)
+
+    class MyModel(MyMixin, Base):
+        __tablename__ = 'atable'
+        c =  Column(Integer,primary_key=True)
+
+Special Directives
+==================
+
+``__declare_last__()``
+~~~~~~~~~~~~~~~~~~~~~~
+
+The ``__declare_last__()`` hook allows definition of
+a class level function that is automatically called by the
+:meth:`.MapperEvents.after_configured` event, which occurs after mappings are
+assumed to be completed and the 'configure' step has finished::
+
+    class MyClass(Base):
+        @classmethod
+        def __declare_last__(cls):
+            ""
+            # do something with mappings
+
+.. versionadded:: 0.7.3
+
+``__declare_first__()``
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Like ``__declare_last__()``, but is called at the beginning of mapper
+configuration via the :meth:`.MapperEvents.before_configured` event::
+
+    class MyClass(Base):
+        @classmethod
+        def __declare_first__(cls):
+            ""
+            # do something before mappings are configured
+
+.. versionadded:: 0.9.3
+
+.. _declarative_abstract:
+
+``__abstract__``
+~~~~~~~~~~~~~~~~~~~
+
+``__abstract__`` causes declarative to skip the production
+of a table or mapper for the class entirely.  A class can be added within a
+hierarchy in the same way as mixin (see :ref:`declarative_mixins`), allowing
+subclasses to extend just from the special class::
+
+    class SomeAbstractBase(Base):
+        __abstract__ = True
+
+        def some_helpful_method(self):
+            ""
+
+        @declared_attr
+        def __mapper_args__(cls):
+            return {"helpful mapper arguments":True}
+
+    class MyMappedClass(SomeAbstractBase):
+        ""
+
+One possible use of ``__abstract__`` is to use a distinct
+:class:`.MetaData` for different bases::
+
+    Base = declarative_base()
+
+    class DefaultBase(Base):
+        __abstract__ = True
+        metadata = MetaData()
+
+    class OtherBase(Base):
+        __abstract__ = True
+        metadata = MetaData()
+
+Above, classes which inherit from ``DefaultBase`` will use one
+:class:`.MetaData` as the registry of tables, and those which inherit from
+``OtherBase`` will use a different one. The tables themselves can then be
+created perhaps within distinct databases::
+
+    DefaultBase.metadata.create_all(some_engine)
+    OtherBase.metadata_create_all(some_other_engine)
+
+.. versionadded:: 0.7.3
+
+Class Constructor
+=================
+
+As a convenience feature, the :func:`declarative_base` sets a default
+constructor on classes which takes keyword arguments, and assigns them
+to the named attributes::
+
+    e = Engineer(primary_language='python')
+
+Sessions
+========
+
+Note that ``declarative`` does nothing special with sessions, and is
+only intended as an easier way to configure mappers and
+:class:`~sqlalchemy.schema.Table` objects.  A typical application
+setup using :class:`~sqlalchemy.orm.scoping.scoped_session` might look like::
+
+    engine = create_engine('postgresql://scott:tiger@localhost/test')
+    Session = scoped_session(sessionmaker(autocommit=False,
+                                          autoflush=False,
+                                          bind=engine))
+    Base = declarative_base()
+
+Mapped instances then make usage of
+:class:`~sqlalchemy.orm.session.Session` in the usual way.

+class DeferredReflection(object):
+    """A helper class for construction of mappings based on
+    a deferred reflection step.
+
+    Normally, declarative can be used with reflection by
+    setting a :class:`.Table` object using autoload=True
+    as the ``__table__`` attribute on a declarative class.
+    The caveat is that the :class:`.Table` must be fully
+    reflected, or at the very least have a primary key column,
+    at the point at which a normal declarative mapping is
+    constructed, meaning the :class:`.Engine` must be available
+    at class declaration time.
+
+    The :class:`.DeferredReflection` mixin moves the construction
+    of mappers to be at a later point, after a specific
+    method is called which first reflects all :class:`.Table`
+    objects created so far.   Classes can define it as such::
+
+        from sqlalchemy.ext.declarative import declarative_base
+        from sqlalchemy.ext.declarative import DeferredReflection
+        Base = declarative_base()
+
+        class MyClass(DeferredReflection, Base):
+            __tablename__ = 'mytable'
+
+    Above, ``MyClass`` is not yet mapped.   After a series of
+    classes have been defined in the above fashion, all tables
+    can be reflected and mappings created using
+    :meth:`.prepare`::
+
+        engine = create_engine("someengine://...")
+        DeferredReflection.prepare(engine)
+
+    The :class:`.DeferredReflection` mixin can be applied to individual
+    classes, used as the base for the declarative base itself,
+    or used in a custom abstract class.   Using an abstract base
+    allows that only a subset of classes to be prepared for a
+    particular prepare step, which is necessary for applications
+    that use more than one engine.  For example, if an application
+    has two engines, you might use two bases, and prepare each
+    separately, e.g.::
+
+        class ReflectedOne(DeferredReflection, Base):
+            __abstract__ = True
+
+        class ReflectedTwo(DeferredReflection, Base):
+            __abstract__ = True
+
+        class MyClass(ReflectedOne):
+            __tablename__ = 'mytable'
+
+        class MyOtherClass(ReflectedOne):
+            __tablename__ = 'myothertable'
+
+        class YetAnotherClass(ReflectedTwo):
+            __tablename__ = 'yetanothertable'
+
+        # ... etc.
+
+    Above, the class hierarchies for ``ReflectedOne`` and
+    ``ReflectedTwo`` can be configured separately::
+
+        ReflectedOne.prepare(engine_one)
+        ReflectedTwo.prepare(engine_two)
+
+    .. versionadded:: 0.8

+"""Define attributes on ORM-mapped classes that have "hybrid" behavior.
+
+"hybrid" means the attribute has distinct behaviors defined at the
+class level and at the instance level.
+
+The :mod:`~sqlalchemy.ext.hybrid` extension provides a special form of
+method decorator, is around 50 lines of code and has almost no
+dependencies on the rest of SQLAlchemy.  It can, in theory, work with
+any descriptor-based expression system.
+
+Consider a mapping ``Interval``, representing integer ``start`` and ``end``
+values. We can define higher level functions on mapped classes that produce
+SQL expressions at the class level, and Python expression evaluation at the
+instance level.  Below, each function decorated with :class:`.hybrid_method` or
+:class:`.hybrid_property` may receive ``self`` as an instance of the class, or
+as the class itself::
+
+    from sqlalchemy import Column, Integer
+    from sqlalchemy.ext.declarative import declarative_base
+    from sqlalchemy.orm import Session, aliased
+    from sqlalchemy.ext.hybrid import hybrid_property, hybrid_method
+
+    Base = declarative_base()
+
+    class Interval(Base):
+        __tablename__ = 'interval'
+
+        id = Column(Integer, primary_key=True)
+        start = Column(Integer, nullable=False)
+        end = Column(Integer, nullable=False)
+
+        def __init__(self, start, end):
+            self.start = start
+            self.end = end
+
+        @hybrid_property
+        def length(self):
+            return self.end - self.start
+
+        @hybrid_method
+        def contains(self,point):
+            return (self.start <= point) & (point < self.end)
+
+        @hybrid_method
+        def intersects(self, other):
+            return self.contains(other.start) | self.contains(other.end)
+
+Above, the ``length`` property returns the difference between the
+``end`` and ``start`` attributes.  With an instance of ``Interval``,
+this subtraction occurs in Python, using normal Python descriptor
+mechanics::
+
+    >>> i1 = Interval(5, 10)
+    >>> i1.length
+    5
+
+When dealing with the ``Interval`` class itself, the :class:`.hybrid_property`
+descriptor evaluates the function body given the ``Interval`` class as
+the argument, which when evaluated with SQLAlchemy expression mechanics
+returns a new SQL expression::
+
+    >>> print Interval.length
+    interval."end" - interval.start
+
+    >>> print Session().query(Interval).filter(Interval.length > 10)
+    SELECT interval.id AS interval_id, interval.start AS interval_start,
+    interval."end" AS interval_end
+    FROM interval
+    WHERE interval."end" - interval.start > :param_1
+
+ORM methods such as :meth:`~.Query.filter_by` generally use ``getattr()`` to
+locate attributes, so can also be used with hybrid attributes::
+
+    >>> print Session().query(Interval).filter_by(length=5)
+    SELECT interval.id AS interval_id, interval.start AS interval_start,
+    interval."end" AS interval_end
+    FROM interval
+    WHERE interval."end" - interval.start = :param_1
+
+The ``Interval`` class example also illustrates two methods,
+``contains()`` and ``intersects()``, decorated with
+:class:`.hybrid_method`. This decorator applies the same idea to
+methods that :class:`.hybrid_property` applies to attributes.   The
+methods return boolean values, and take advantage of the Python ``|``
+and ``&`` bitwise operators to produce equivalent instance-level and
+SQL expression-level boolean behavior::
+
+    >>> i1.contains(6)
+    True
+    >>> i1.contains(15)
+    False
+    >>> i1.intersects(Interval(7, 18))
+    True
+    >>> i1.intersects(Interval(25, 29))
+    False
+
+    >>> print Session().query(Interval).filter(Interval.contains(15))
+    SELECT interval.id AS interval_id, interval.start AS interval_start,
+    interval."end" AS interval_end
+    FROM interval
+    WHERE interval.start <= :start_1 AND interval."end" > :end_1
+
+    >>> ia = aliased(Interval)
+    >>> print Session().query(Interval, ia).filter(Interval.intersects(ia))
+    SELECT interval.id AS interval_id, interval.start AS interval_start,
+    interval."end" AS interval_end, interval_1.id AS interval_1_id,
+    interval_1.start AS interval_1_start, interval_1."end" AS interval_1_end
+    FROM interval, interval AS interval_1
+    WHERE interval.start <= interval_1.start
+        AND interval."end" > interval_1.start
+        OR interval.start <= interval_1."end"
+        AND interval."end" > interval_1."end"
+
+Defining Expression Behavior Distinct from Attribute Behavior
+--------------------------------------------------------------
+
+Our usage of the ``&`` and ``|`` bitwise operators above was
+fortunate, considering our functions operated on two boolean values to
+return a new one.   In many cases, the construction of an in-Python
+function and a SQLAlchemy SQL expression have enough differences that
+two separate Python expressions should be defined.  The
+:mod:`~sqlalchemy.ext.hybrid` decorators define the
+:meth:`.hybrid_property.expression` modifier for this purpose.   As an
+example we'll define the radius of the interval, which requires the
+usage of the absolute value function::
+
+    from sqlalchemy import func
+
+    class Interval(object):
+        # ...
+
+        @hybrid_property
+        def radius(self):
+            return abs(self.length) / 2
+
+        @radius.expression
+        def radius(cls):
+            return func.abs(cls.length) / 2
+
+Above the Python function ``abs()`` is used for instance-level
+operations, the SQL function ``ABS()`` is used via the :attr:`.func`
+object for class-level expressions::
+
+    >>> i1.radius
+    2
+
+    >>> print Session().query(Interval).filter(Interval.radius > 5)
+    SELECT interval.id AS interval_id, interval.start AS interval_start,
+        interval."end" AS interval_end
+    FROM interval
+    WHERE abs(interval."end" - interval.start) / :abs_1 > :param_1
+
+Defining Setters
+----------------
+
+Hybrid properties can also define setter methods.  If we wanted
+``length`` above, when set, to modify the endpoint value::
+
+    class Interval(object):
+        # ...
+
+        @hybrid_property
+        def length(self):
+            return self.end - self.start
+
+        @length.setter
+        def length(self, value):
+            self.end = self.start + value
+
+The ``length(self, value)`` method is now called upon set::
+
+    >>> i1 = Interval(5, 10)
+    >>> i1.length
+    5
+    >>> i1.length = 12
+    >>> i1.end
+    17
+
+Working with Relationships
+--------------------------
+
+There's no essential difference when creating hybrids that work with
+related objects as opposed to column-based data. The need for distinct
+expressions tends to be greater.  Two variants of we'll illustrate
+are the "join-dependent" hybrid, and the "correlated subquery" hybrid.
+
+Join-Dependent Relationship Hybrid
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Consider the following declarative
+mapping which relates a ``User`` to a ``SavingsAccount``::
+
+    from sqlalchemy import Column, Integer, ForeignKey, Numeric, String
+    from sqlalchemy.orm import relationship
+    from sqlalchemy.ext.declarative import declarative_base
+    from sqlalchemy.ext.hybrid import hybrid_property
+

+
+        @hybrid_property
+        def balance(self):
+            if self.accounts:
+                return self.accounts[0].balance
+            else:
+                return None
+
+        @balance.setter
+        def balance(self, value):
+            if not self.accounts:
+                account = Account(owner=self)
+            else:
+                account = self.accounts[0]
+            account.balance = value
+
+        @balance.expression
+        def balance(cls):
+            return SavingsAccount.balance
+
+The above hybrid property ``balance`` works with the first
+``SavingsAccount`` entry in the list of accounts for this user.   The
+in-Python getter/setter methods can treat ``accounts`` as a Python
+list available on ``self``.
+
+However, at the expression level, it's expected that the ``User`` class will
+be used in an appropriate context such that an appropriate join to
+``SavingsAccount`` will be present::
+
+    >>> print Session().query(User, User.balance).\\
+    ...     join(User.accounts).filter(User.balance > 5000)
+    SELECT "user".id AS user_id, "user".name AS user_name,
+    account.balance AS account_balance
+    FROM "user" JOIN account ON "user".id = account.user_id
+    WHERE account.balance > :balance_1
+
+Note however, that while the instance level accessors need to worry
+about whether ``self.accounts`` is even present, this issue expresses
+itself differently at the SQL expression level, where we basically
+would use an outer join::
+
+    >>> from sqlalchemy import or_
+    >>> print (Session().query(User, User.balance).outerjoin(User.accounts).
+    ...         filter(or_(User.balance < 5000, User.balance == None)))
+    SELECT "user".id AS user_id, "user".name AS user_name,
+    account.balance AS account_balance
+    FROM "user" LEFT OUTER JOIN account ON "user".id = account.user_id
+    WHERE account.balance <  :balance_1 OR account.balance IS NULL
+
+Correlated Subquery Relationship Hybrid
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+We can, of course, forego being dependent on the enclosing query's usage
+of joins in favor of the correlated subquery, which can portably be packed
+into a single column expression. A correlated subquery is more portable, but
+often performs more poorly at the SQL level. Using the same technique
+illustrated at :ref:`mapper_column_property_sql_expressions`,
+we can adjust our ``SavingsAccount`` example to aggregate the balances for
+*all* accounts, and use a correlated subquery for the column expression::
+
+    from sqlalchemy import Column, Integer, ForeignKey, Numeric, String
+    from sqlalchemy.orm import relationship
+    from sqlalchemy.ext.declarative import declarative_base
+    from sqlalchemy.ext.hybrid import hybrid_property
+    from sqlalchemy import select, func
+
+    Base = declarative_base()
+
+    class SavingsAccount(Base):
+        __tablename__ = 'account'
+        id = Column(Integer, primary_key=True)
+        user_id = Column(Integer, ForeignKey('user.id'), nullable=False)
+        balance = Column(Numeric(15, 5))
+
+    class User(Base):
+        __tablename__ = 'user'
+        id = Column(Integer, primary_key=True)
+        name = Column(String(100), nullable=False)
+
+        accounts = relationship("SavingsAccount", backref="owner")
+
+        @hybrid_property
+        def balance(self):
+            return sum(acc.balance for acc in self.accounts)
+
+        @balance.expression
+        def balance(cls):
+            return select([func.sum(SavingsAccount.balance)]).\\
+                    where(SavingsAccount.user_id==cls.id).\\
+                    label('total_balance')
+
+The above recipe will give us the ``balance`` column which renders
+a correlated SELECT::
+
+    >>> print s.query(User).filter(User.balance > 400)
+    SELECT "user".id AS user_id, "user".name AS user_name
+    FROM "user"
+    WHERE (SELECT sum(account.balance) AS sum_1
+    FROM account
+    WHERE account.user_id = "user".id) > :param_1
+
+.. _hybrid_custom_comparators:
+
+Building Custom Comparators
+---------------------------
+
+The hybrid property also includes a helper that allows construction of
+custom comparators. A comparator object allows one to customize the
+behavior of each SQLAlchemy expression operator individually.  They
+are useful when creating custom types that have some highly
+idiosyncratic behavior on the SQL side.
+
+The example class below allows case-insensitive comparisons on the attribute
+named ``word_insensitive``::
+
+    from sqlalchemy.ext.hybrid import Comparator, hybrid_property
+    from sqlalchemy import func, Column, Integer, String
+    from sqlalchemy.orm import Session
+    from sqlalchemy.ext.declarative import declarative_base
+
+    Base = declarative_base()
+
+    class CaseInsensitiveComparator(Comparator):
+        def __eq__(self, other):
+            return func.lower(self.__clause_element__()) == func.lower(other)
+
+    class SearchWord(Base):
+        __tablename__ = 'searchword'
+        id = Column(Integer, primary_key=True)
+        word = Column(String(255), nullable=False)
+
+        @hybrid_property
+        def word_insensitive(self):
+            return self.word.lower()
+
+        @word_insensitive.comparator
+        def word_insensitive(cls):
+            return CaseInsensitiveComparator(cls.word)
+
+Above, SQL expressions against ``word_insensitive`` will apply the ``LOWER()``
+SQL function to both sides::
+
+    >>> print Session().query(SearchWord).filter_by(word_insensitive="Trucks")
+    SELECT searchword.id AS searchword_id, searchword.word AS searchword_word
+    FROM searchword
+    WHERE lower(searchword.word) = lower(:lower_1)
+
+The ``CaseInsensitiveComparator`` above implements part of the
+:class:`.ColumnOperators` interface.   A "coercion" operation like
+lowercasing can be applied to all comparison operations (i.e. ``eq``,
+``lt``, ``gt``, etc.) using :meth:`.Operators.operate`::
+
+    class CaseInsensitiveComparator(Comparator):
+        def operate(self, op, other):
+            return op(func.lower(self.__clause_element__()), func.lower(other))
+
+Hybrid Value Objects
+--------------------
+
+Note in our previous example, if we were to compare the
+``word_insensitive`` attribute of a ``SearchWord`` instance to a plain
+Python string, the plain Python string would not be coerced to lower
+case - the ``CaseInsensitiveComparator`` we built, being returned by
+``@word_insensitive.comparator``, only applies to the SQL side.
+
+A more comprehensive form of the custom comparator is to construct a
+*Hybrid Value Object*. This technique applies the target value or
+expression to a value object which is then returned by the accessor in
+all cases.   The value object allows control of all operations upon
+the value as well as how compared values are treated, both on the SQL
+expression side as well as the Python value side.   Replacing the
+previous ``CaseInsensitiveComparator`` class with a new
+``CaseInsensitiveWord`` class::
+
+    class CaseInsensitiveWord(Comparator):
+        "Hybrid value representing a lower case representation of a word."
+
+        def __init__(self, word):
+            if isinstance(word, basestring):
+                self.word = word.lower()
+            elif isinstance(word, CaseInsensitiveWord):
+                self.word = word.word
+            else:
+                self.word = func.lower(word)
+
+        def operate(self, op, other):
+            if not isinstance(other, CaseInsensitiveWord):
+                other = CaseInsensitiveWord(other)
+            return op(self.word, other.word)
+
+        def __clause_element__(self):
+            return self.word
+
+        def __str__(self):
+            return self.word
+
+        key = 'word'
+        "Label to apply to Query tuple results"
+
+Above, the ``CaseInsensitiveWord`` object represents ``self.word``,
+which may be a SQL function, or may be a Python native.   By
+overriding ``operate()`` and ``__clause_element__()`` to work in terms
+of ``self.word``, all comparison operations will work against the
+"converted" form of ``word``, whether it be SQL side or Python side.
+Our ``SearchWord`` class can now deliver the ``CaseInsensitiveWord``
+object unconditionally from a single hybrid call::
+
+    class SearchWord(Base):
+        __tablename__ = 'searchword'
+        id = Column(Integer, primary_key=True)
+        word = Column(String(255), nullable=False)
+
+        @hybrid_property
+        def word_insensitive(self):
+            return CaseInsensitiveWord(self.word)
+
+The ``word_insensitive`` attribute now has case-insensitive comparison
+behavior universally, including SQL expression vs. Python expression
+(note the Python value is converted to lower case on the Python side
+here)::
+
+    >>> print Session().query(SearchWord).filter_by(word_insensitive="Trucks")
+    SELECT searchword.id AS searchword_id, searchword.word AS searchword_word
+    FROM searchword
+    WHERE lower(searchword.word) = :lower_1
+
+SQL expression versus SQL expression::
+
+    >>> sw1 = aliased(SearchWord)
+    >>> sw2 = aliased(SearchWord)
+    >>> print Session().query(
+    ...                    sw1.word_insensitive,
+    ...                    sw2.word_insensitive).\\
+    ...                        filter(
+    ...                            sw1.word_insensitive > sw2.word_insensitive
+    ...                        )
+    SELECT lower(searchword_1.word) AS lower_1,
+    lower(searchword_2.word) AS lower_2
+    FROM searchword AS searchword_1, searchword AS searchword_2
+    WHERE lower(searchword_1.word) > lower(searchword_2.word)
+
+Python only expression::
+
+    >>> ws1 = SearchWord(word="SomeWord")
+    >>> ws1.word_insensitive == "sOmEwOrD"
+    True
+    >>> ws1.word_insensitive == "XOmEwOrX"
+    False
+    >>> print ws1.word_insensitive
+    someword
+
+The Hybrid Value pattern is very useful for any kind of value that may
+have multiple representations, such as timestamps, time deltas, units
+of measurement, currencies and encrypted passwords.

+.. _hybrid_transformers:
+
+Building Transformers
+----------------------
+
+A *transformer* is an object which can receive a :class:`.Query`
+object and return a new one.   The :class:`.Query` object includes a
+method :meth:`.with_transformation` that returns a new :class:`.Query`
+transformed by the given function.
+
+We can combine this with the :class:`.Comparator` class to produce one type
+of recipe which can both set up the FROM clause of a query as well as assign
+filtering criterion.
+
+Consider a mapped class ``Node``, which assembles using adjacency list
+into a hierarchical tree pattern::
+
+    from sqlalchemy import Column, Integer, ForeignKey
+    from sqlalchemy.orm import relationship
+    from sqlalchemy.ext.declarative import declarative_base
+    Base = declarative_base()
+
+    class Node(Base):
+        __tablename__ = 'node'
+        id =Column(Integer, primary_key=True)
+        parent_id = Column(Integer, ForeignKey('node.id'))
+        parent = relationship("Node", remote_side=id)
+
+Suppose we wanted to add an accessor ``grandparent``.  This would
+return the ``parent`` of ``Node.parent``.  When we have an instance of
+``Node``, this is simple::
+
+    from sqlalchemy.ext.hybrid import hybrid_property
+
+    class Node(Base):
+        # ...
+
+        @hybrid_property
+        def grandparent(self):
+            return self.parent.parent
+
+For the expression, things are not so clear.   We'd need to construct
+a :class:`.Query` where we :meth:`~.Query.join` twice along
+``Node.parent`` to get to the ``grandparent``.   We can instead return
+a transforming callable that we'll combine with the
+:class:`.Comparator` class to receive any :class:`.Query` object, and
+return a new one that's joined to the ``Node.parent`` attribute and
+filtered based on the given criterion::
+
+    from sqlalchemy.ext.hybrid import Comparator
+
+    class GrandparentTransformer(Comparator):
+        def operate(self, op, other):
+            def transform(q):
+                cls = self.__clause_element__()
+                parent_alias = aliased(cls)
+                return q.join(parent_alias, cls.parent).\\
+                            filter(op(parent_alias.parent, other))
+            return transform
+
+    Base = declarative_base()
+
+    class Node(Base):
+        __tablename__ = 'node'
+        id =Column(Integer, primary_key=True)
+        parent_id = Column(Integer, ForeignKey('node.id'))
+        parent = relationship("Node", remote_side=id)
+
+        @hybrid_property
+        def grandparent(self):
+            return self.parent.parent
+
+        @grandparent.comparator
+        def grandparent(cls):
+            return GrandparentTransformer(cls)
+
+The ``GrandparentTransformer`` overrides the core
+:meth:`.Operators.operate` method at the base of the
+:class:`.Comparator` hierarchy to return a query-transforming
+callable, which then runs the given comparison operation in a
+particular context. Such as, in the example above, the ``operate``
+method is called, given the :attr:`.Operators.eq` callable as well as
+the right side of the comparison ``Node(id=5)``.  A function
+``transform`` is then returned which will transform a :class:`.Query`
+first to join to ``Node.parent``, then to compare ``parent_alias``
+using :attr:`.Operators.eq` against the left and right sides, passing
+into :class:`.Query.filter`:
+
+.. sourcecode:: pycon+sql
+
+    >>> from sqlalchemy.orm import Session
+    >>> session = Session()
+    {sql}>>> session.query(Node).\\
+    ...        with_transformation(Node.grandparent==Node(id=5)).\\
+    ...        all()
+    SELECT node.id AS node_id, node.parent_id AS node_parent_id
+    FROM node JOIN node AS node_1 ON node_1.id = node.parent_id
+    WHERE :param_1 = node_1.parent_id
+    {stop}
+
+We can modify the pattern to be more verbose but flexible by separating
+the "join" step from the "filter" step.  The tricky part here is ensuring
+that successive instances of ``GrandparentTransformer`` use the same
+:class:`.AliasedClass` object against ``Node``.  Below we use a simple
+memoizing approach that associates a ``GrandparentTransformer``
+with each class::
+
+    class Node(Base):
+
+        # ...
+
+        @grandparent.comparator
+        def grandparent(cls):
+            # memoize a GrandparentTransformer
+            # per class
+            if '_gp' not in cls.__dict__:
+                cls._gp = GrandparentTransformer(cls)
+            return cls._gp
+
+    class GrandparentTransformer(Comparator):
+
+        def __init__(self, cls):
+            self.parent_alias = aliased(cls)
+
+        @property
+        def join(self):
+            def go(q):
+                return q.join(self.parent_alias, Node.parent)
+            return go
+
+        def operate(self, op, other):
+            return op(self.parent_alias.parent, other)
+
+.. sourcecode:: pycon+sql
+
+    {sql}>>> session.query(Node).\\
+    ...            with_transformation(Node.grandparent.join).\\
+    ...            filter(Node.grandparent==Node(id=5))
+    SELECT node.id AS node_id, node.parent_id AS node_parent_id
+    FROM node JOIN node AS node_1 ON node_1.id = node.parent_id
+    WHERE :param_1 = node_1.parent_id
+    {stop}
+
+The "transformer" pattern is an experimental pattern that starts
+to make usage of some functional programming paradigms.
+While it's only recommended for advanced and/or patient developers,
+there's probably a whole lot of amazing things it can be used for.

+"""Extensible class instrumentation.

+The :mod:`sqlalchemy.ext.instrumentation` package provides for alternate

+
+Establishing Mutability on Scalar Column Values
+===============================================
+
+A typical example of a "mutable" structure is a Python dictionary.
+Following the example introduced in :ref:`types_toplevel`, we
+begin with a custom type that marshals Python dictionaries into
+JSON strings before being persisted::
+
+    from sqlalchemy.types import TypeDecorator, VARCHAR
+    import json
+
+    class JSONEncodedDict(TypeDecorator):
+        "Represents an immutable structure as a json-encoded string."
+
+        impl = VARCHAR
+
+        def process_bind_param(self, value, dialect):
+            if value is not None:
+                value = json.dumps(value)
+            return value
+
+        def process_result_value(self, value, dialect):
+            if value is not None:
+                value = json.loads(value)
+            return value
+
+The usage of ``json`` is only for the purposes of example. The
+:mod:`sqlalchemy.ext.mutable` extension can be used
+with any type whose target Python type may be mutable, including
+:class:`.PickleType`, :class:`.postgresql.ARRAY`, etc.
+
+When using the :mod:`sqlalchemy.ext.mutable` extension, the value itself
+tracks all parents which reference it.  Below, we illustrate the a simple
+version of the :class:`.MutableDict` dictionary object, which applies
+the :class:`.Mutable` mixin to a plain Python dictionary::
+
+    from sqlalchemy.ext.mutable import Mutable
+
+    class MutableDict(Mutable, dict):
+        @classmethod
+        def coerce(cls, key, value):
+            "Convert plain dictionaries to MutableDict."
+
+            if not isinstance(value, MutableDict):
+                if isinstance(value, dict):
+                    return MutableDict(value)
+
+                # this call will raise ValueError
+                return Mutable.coerce(key, value)
+            else:
+                return value
+
+        def __setitem__(self, key, value):
+            "Detect dictionary set events and emit change events."
+
+            dict.__setitem__(self, key, value)
+            self.changed()
+
+        def __delitem__(self, key):
+            "Detect dictionary del events and emit change events."
+
+            dict.__delitem__(self, key)
+            self.changed()
+
+The above dictionary class takes the approach of subclassing the Python
+built-in ``dict`` to produce a dict
+subclass which routes all mutation events through ``__setitem__``.  There are
+variants on this approach, such as subclassing ``UserDict.UserDict`` or
+``collections.MutableMapping``; the part that's important to this example is
+that the :meth:`.Mutable.changed` method is called whenever an in-place
+change to the datastructure takes place.
+
+We also redefine the :meth:`.Mutable.coerce` method which will be used to
+convert any values that are not instances of ``MutableDict``, such
+as the plain dictionaries returned by the ``json`` module, into the
+appropriate type.  Defining this method is optional; we could just as well
+created our ``JSONEncodedDict`` such that it always returns an instance
+of ``MutableDict``, and additionally ensured that all calling code
+uses ``MutableDict`` explicitly.  When :meth:`.Mutable.coerce` is not
+overridden, any values applied to a parent object which are not instances
+of the mutable type will raise a ``ValueError``.
+
+Our new ``MutableDict`` type offers a class method
+:meth:`~.Mutable.as_mutable` which we can use within column metadata
+to associate with types. This method grabs the given type object or
+class and associates a listener that will detect all future mappings
+of this type, applying event listening instrumentation to the mapped
+attribute. Such as, with classical table metadata::
+
+    from sqlalchemy import Table, Column, Integer
+
+    my_data = Table('my_data', metadata,
+        Column('id', Integer, primary_key=True),
+        Column('data', MutableDict.as_mutable(JSONEncodedDict))
+    )
+
+Above, :meth:`~.Mutable.as_mutable` returns an instance of ``JSONEncodedDict``
+(if the type object was not an instance already), which will intercept any
+attributes which are mapped against this type.  Below we establish a simple
+mapping against the ``my_data`` table::
+
+    from sqlalchemy import mapper
+
+    class MyDataClass(object):
+        pass
+
+    # associates mutation listeners with MyDataClass.data
+    mapper(MyDataClass, my_data)
+
+The ``MyDataClass.data`` member will now be notified of in place changes
+to its value.
+
+There's no difference in usage when using declarative::
+
+    from sqlalchemy.ext.declarative import declarative_base
+
+    Base = declarative_base()
+
+    class MyDataClass(Base):
+        __tablename__ = 'my_data'
+        id = Column(Integer, primary_key=True)
+        data = Column(MutableDict.as_mutable(JSONEncodedDict))
+
+Any in-place changes to the ``MyDataClass.data`` member
+will flag the attribute as "dirty" on the parent object::
+
+    >>> from sqlalchemy.orm import Session
+
+    >>> sess = Session()
+    >>> m1 = MyDataClass(data={'value1':'foo'})
+    >>> sess.add(m1)
+    >>> sess.commit()
+
+    >>> m1.data['value1'] = 'bar'
+    >>> assert m1 in sess.dirty
+    True
+
+The ``MutableDict`` can be associated with all future instances
+of ``JSONEncodedDict`` in one step, using
+:meth:`~.Mutable.associate_with`.  This is similar to
+:meth:`~.Mutable.as_mutable` except it will intercept all occurrences
+of ``MutableDict`` in all mappings unconditionally, without
+the need to declare it individually::
+
+    MutableDict.associate_with(JSONEncodedDict)
+
+    class MyDataClass(Base):
+        __tablename__ = 'my_data'
+        id = Column(Integer, primary_key=True)
+        data = Column(JSONEncodedDict)
+
+
+Supporting Pickling
+--------------------
+
+The key to the :mod:`sqlalchemy.ext.mutable` extension relies upon the
+placement of a ``weakref.WeakKeyDictionary`` upon the value object, which
+stores a mapping of parent mapped objects keyed to the attribute name under
+which they are associated with this value. ``WeakKeyDictionary`` objects are
+not picklable, due to the fact that they contain weakrefs and function
+callbacks. In our case, this is a good thing, since if this dictionary were
+picklable, it could lead to an excessively large pickle size for our value
+objects that are pickled by themselves outside of the context of the parent.
+The developer responsibility here is only to provide a ``__getstate__`` method
+that excludes the :meth:`~MutableBase._parents` collection from the pickle
+stream::
+
+    class MyMutableType(Mutable):
+        def __getstate__(self):
+            d = self.__dict__.copy()
+            d.pop('_parents', None)
+            return d
+
+With our dictionary example, we need to return the contents of the dict itself
+(and also restore them on __setstate__)::
+
+    class MutableDict(Mutable, dict):
+        # ....
+
+        def __getstate__(self):
+            return dict(self)
+
+        def __setstate__(self, state):
+            self.update(state)
+
+In the case that our mutable value object is pickled as it is attached to one
+or more parent objects that are also part of the pickle, the :class:`.Mutable`
+mixin will re-establish the :attr:`.Mutable._parents` collection on each value
+object as the owning parents themselves are unpickled.
+
+.. _mutable_composites:
+
+Establishing Mutability on Composites
+=====================================
+
+Composites are a special ORM feature which allow a single scalar attribute to
+be assigned an object value which represents information "composed" from one
+or more columns from the underlying mapped table. The usual example is that of
+a geometric "point", and is introduced in :ref:`mapper_composite`.
+
+.. versionchanged:: 0.7
+    The internals of :func:`.orm.composite` have been
+    greatly simplified and in-place mutation detection is no longer enabled by
+    default; instead, the user-defined value must detect changes on its own and
+    propagate them to all owning parents. The :mod:`sqlalchemy.ext.mutable`
+    extension provides the helper class :class:`.MutableComposite`, which is a
+    slight variant on the :class:`.Mutable` class.
+
+As is the case with :class:`.Mutable`, the user-defined composite class
+subclasses :class:`.MutableComposite` as a mixin, and detects and delivers
+change events to its parents via the :meth:`.MutableComposite.changed` method.
+In the case of a composite class, the detection is usually via the usage of
+Python descriptors (i.e. ``@property``), or alternatively via the special
+Python method ``__setattr__()``. Below we expand upon the ``Point`` class
+introduced in :ref:`mapper_composite` to subclass :class:`.MutableComposite`
+and to also route attribute set events via ``__setattr__`` to the
+:meth:`.MutableComposite.changed` method::
+
+    from sqlalchemy.ext.mutable import MutableComposite
+
+    class Point(MutableComposite):
+        def __init__(self, x, y):
+            self.x = x
+            self.y = y
+
+        def __setattr__(self, key, value):
+            "Intercept set events"
+
+            # set the attribute
+            object.__setattr__(self, key, value)
+
+            # alert all parents to the change
+            self.changed()
+
+        def __composite_values__(self):
+            return self.x, self.y
+
+        def __eq__(self, other):
+            return isinstance(other, Point) and \\
+                other.x == self.x and \\
+                other.y == self.y
+
+        def __ne__(self, other):
+            return not self.__eq__(other)
+
+The :class:`.MutableComposite` class uses a Python metaclass to automatically
+establish listeners for any usage of :func:`.orm.composite` that specifies our
+``Point`` type. Below, when ``Point`` is mapped to the ``Vertex`` class,
+listeners are established which will route change events from ``Point``
+objects to each of the ``Vertex.start`` and ``Vertex.end`` attributes::
+
+    from sqlalchemy.orm import composite, mapper
+    from sqlalchemy import Table, Column
+
+    vertices = Table('vertices', metadata,
+        Column('id', Integer, primary_key=True),
+        Column('x1', Integer),
+        Column('y1', Integer),
+        Column('x2', Integer),
+        Column('y2', Integer),
+        )
+
+    class Vertex(object):
+        pass
+
+    mapper(Vertex, vertices, properties={
+        'start': composite(Point, vertices.c.x1, vertices.c.y1),
+        'end': composite(Point, vertices.c.x2, vertices.c.y2)
+    })
+
+Any in-place changes to the ``Vertex.start`` or ``Vertex.end`` members
+will flag the attribute as "dirty" on the parent object::
+
+    >>> from sqlalchemy.orm import Session
+
+    >>> sess = Session()
+    >>> v1 = Vertex(start=Point(3, 4), end=Point(12, 15))
+    >>> sess.add(v1)
+    >>> sess.commit()
+
+    >>> v1.end.x = 8
+    >>> assert v1 in sess.dirty
+    True
+
+Coercing Mutable Composites
+---------------------------
+
+The :meth:`.MutableBase.coerce` method is also supported on composite types.
+In the case of :class:`.MutableComposite`, the :meth:`.MutableBase.coerce`
+method is only called for attribute set operations, not load operations.
+Overriding the :meth:`.MutableBase.coerce` method is essentially equivalent
+to using a :func:`.validates` validation routine for all attributes which
+make use of the custom composite type::
+
+    class Point(MutableComposite):
+        # other Point methods
+        # ...
+
+        def coerce(cls, key, value):
+            if isinstance(value, tuple):
+                value = Point(*value)
+            elif not isinstance(value, Point):
+                raise ValueError("tuple or Point expected")
+            return value
+
+.. versionadded:: 0.7.10,0.8.0b2
+    Support for the :meth:`.MutableBase.coerce` method in conjunction with
+    objects of type :class:`.MutableComposite`.
+
+Supporting Pickling
+--------------------
+
+As is the case with :class:`.Mutable`, the :class:`.MutableComposite` helper
+class uses a ``weakref.WeakKeyDictionary`` available via the
+:meth:`MutableBase._parents` attribute which isn't picklable. If we need to
+pickle instances of ``Point`` or its owning class ``Vertex``, we at least need
+to define a ``__getstate__`` that doesn't include the ``_parents`` dictionary.
+Below we define both a ``__getstate__`` and a ``__setstate__`` that package up
+the minimal form of our ``Point`` class::
+
+    class Point(MutableComposite):
+        # ...
+
+        def __getstate__(self):
+            return self.x, self.y
+
+        def __setstate__(self, state):
+            self.x, self.y = state
+
+As with :class:`.Mutable`, the :class:`.MutableComposite` augments the
+pickling process of the parent's object-relational state so that the
+:meth:`MutableBase._parents` collection is restored to all ``Point`` objects.

+``orderinglist`` is a helper for mutable ordered relationships.  It will

+in a related ``bullet`` table.   The bullets within a slide are
+displayed in order based on the value of the ``position`` column in the
+``bullet`` table.   As entries are reordered in memory, the value of the
+``position`` attribute should be updated to reflect the new sort order::
+
+
+    Base = declarative_base()
+
+    class Slide(Base):
+        __tablename__ = 'slide'
+
+        id = Column(Integer, primary_key=True)
+        name = Column(String)
+
+        bullets = relationship("Bullet", order_by="Bullet.position")
+
+    class Bullet(Base):
+        __tablename__ = 'bullet'
+        id = Column(Integer, primary_key=True)
+        slide_id = Column(Integer, ForeignKey('slide.id'))
+        position = Column(Integer)
+        text = Column(String)
+
+The standard relationship mapping will produce a list-like attribute on each
+``Slide`` containing all related ``Bullet`` objects,
+but coping with changes in ordering is not handled automatically.
+When appending a ``Bullet`` into ``Slide.bullets``, the ``Bullet.position``
+attribute will remain unset until manually assigned.   When the ``Bullet``
+is inserted into the middle of the list, the following ``Bullet`` objects
+will also need to be renumbered.
+
+The :class:`.OrderingList` object automates this task, managing the
+``position`` attribute on all ``Bullet`` objects in the collection.  It is
+constructed using the :func:`.ordering_list` factory::
+
+    from sqlalchemy.ext.orderinglist import ordering_list
+
+    Base = declarative_base()
+
+    class Slide(Base):
+        __tablename__ = 'slide'
+
+        id = Column(Integer, primary_key=True)
+        name = Column(String)
+
+        bullets = relationship("Bullet", order_by="Bullet.position",
+                                collection_class=ordering_list('position'))
+
+    class Bullet(Base):
+        __tablename__ = 'bullet'
+        id = Column(Integer, primary_key=True)
+        slide_id = Column(Integer, ForeignKey('slide.id'))
+        position = Column(Integer)
+        text = Column(String)
+
+With the above mapping the ``Bullet.position`` attribute is managed::
+
+    s = Slide()
+    s.bullets.append(Bullet())
+    s.bullets.append(Bullet())
+    s.bullets[1].position
+    >>> 1
+    s.bullets.insert(1, Bullet())
+    s.bullets[2].position
+    >>> 2
+
+The :class:`.OrderingList` construct only works with **changes** to a
+collection, and not the initial load from the database, and requires that the
+list be sorted when loaded.  Therefore, be sure to specify ``order_by`` on the
+:func:`.relationship` against the target ordering attribute, so that the
+ordering is correct when first loaded.
+
+.. warning::
+
+  :class:`.OrderingList` only provides limited functionality when a primary
+  key column or unique column is the target of the sort.  Operations
+  that are unsupported or are problematic include:
+
+    * two entries must trade values.  This is not supported directly in the
+      case of a primary key or unique constraint because it means at least
+      one row would need to be temporarily removed first, or changed to
+      a third, neutral value while the switch occurs.
+
+    * an entry must be deleted in order to make room for a new entry.
+      SQLAlchemy's unit of work performs all INSERTs before DELETEs within a
+      single flush.  In the case of a primary key, it will trade
+      an INSERT/DELETE of the same primary key for an UPDATE statement in order
+      to lessen the impact of this limitation, however this does not take place
+      for a UNIQUE column.
+      A future feature will allow the "DELETE before INSERT" behavior to be
+      possible, allevating this limitation, though this feature will require
+      explicit configuration at the mapper level for sets of columns that
+      are to be handled in this way.
+
+:func:`.ordering_list` takes the name of the related object's ordering
+attribute as an argument.  By default, the zero-based integer index of the
+object's position in the :func:`.ordering_list` is synchronized with the
+ordering attribute: index 0 will get position 0, index 1 position 1, etc.  To
+start numbering at 1 or some other integer, provide ``count_from=1``.

+"""Serializer/Deserializer objects for usage with SQLAlchemy query structures,
+allowing "contextual" deserialization.
+
+Any SQLAlchemy query structure, either based on sqlalchemy.sql.*
+or sqlalchemy.orm.* can be used.  The mappers, Tables, Columns, Session
+etc. which are referenced by the structure are not persisted in serialized
+form, but are instead re-associated with the query structure
+when it is deserialized.
+
+Usage is nearly the same as that of the standard Python pickle module::
+
+    from sqlalchemy.ext.serializer import loads, dumps
+    metadata = MetaData(bind=some_engine)
+    Session = scoped_session(sessionmaker())
+
+    # ... define mappers
+
+    query = Session.query(MyClass).
+        filter(MyClass.somedata=='foo').order_by(MyClass.sortkey)
+
+    # pickle the query
+    serialized = dumps(query)
+
+    # unpickle.  Pass in metadata + scoped_session
+    query2 = loads(serialized, metadata, Session)
+
+    print query2.all()
+
+Similar restrictions as when using raw pickle apply; mapped classes must be
+themselves be pickleable, meaning they are importable from a module-level
+namespace.
+
+The serializer module is only appropriate for query structures.  It is not
+needed for:
+
+* instances of user-defined classes.   These contain no references to engines,
+  sessions or expression constructs in the typical case and can be serialized
+  directly.
+
+* Table metadata that is to be loaded entirely from the serialized structure
+  (i.e. is not already declared in the application).   Regular
+  pickle.loads()/dumps() can be used to fully dump any ``MetaData`` object,
+  typically one which was reflected from an existing database at some previous
+  point in time.  The serializer module is specifically for the opposite case,
+  where the Table metadata is already present in memory.

+public API for viewing the configuration and construction
+of in-memory objects.   Depending on the type of object
+passed to :func:`.inspect`, the return value will either be
+a related object which provides a known interface, or in many
+cases it will return the object itself.
+
+The rationale for :func:`.inspect` is twofold.  One is that
+it replaces the need to be aware of a large variety of "information
+getting" functions in SQLAlchemy, such as :meth:`.Inspector.from_engine`,
+:func:`.orm.attributes.instance_state`, :func:`.orm.class_mapper`,
+and others.    The other is that the return value of :func:`.inspect`
+is guaranteed to obey a documented API, thus allowing third party
+tools which build on top of SQLAlchemy configurations to be constructed
+in a forwards-compatible way.
+
+.. versionadded:: 0.8 The :func:`.inspect` system is introduced
+   as of version 0.8.

+    All of the standard connection :class:`~sqlalchemy.pool.Pool` types can
+    accept event listeners for key connection lifecycle events:
+    creation, pool check-out and check-in.  There are no events fired
+    when a connection closes.
+
+    For any given DB-API connection, there will be one ``connect``
+    event, `n` number of ``checkout`` events, and either `n` or `n - 1`
+    ``checkin`` events.  (If a ``Connection`` is detached from its
+    pool via the ``detach()`` method, it won't be checked back in.)
+
+    These are low-level events for low-level objects: raw Python
+    DB-API connections, without the conveniences of the SQLAlchemy
+    ``Connection`` wrapper, ``Dialect`` services or ``ClauseElement``
+    execution.  If you execute SQL through the connection, explicitly
+    closing all cursors and other resources is recommended.
+
+    Events also receive a ``_ConnectionRecord``, a long-lived internal
+    ``Pool`` object that basically represents a "slot" in the
+    connection pool.  ``_ConnectionRecord`` objects have one public
+    attribute of note: ``info``, a dictionary whose contents are
+    scoped to the lifetime of the DB-API connection managed by the
+    record.  You can use this shared storage area however you like.
+
+    There is no need to subclass ``PoolListener`` to handle events.
+    Any class that implements one or more of these methods can be used
+    as a pool listener.  The ``Pool`` will inspect the methods
+    provided by a listener object and add the listener to one or more
+    internal event queues based on its capabilities.  In terms of
+    efficiency and function call overhead, you're much better off only
+    providing implementations for the hooks you'll be using.

+
+"""Support for collections of mapped entities.
+
+The collections package supplies the machinery used to inform the ORM of
+collection membership changes.  An instrumentation via decoration approach is
+used, allowing arbitrary types (including built-ins) to be used as entity
+collections without requiring inheritance from a base class.
+
+Instrumentation decoration relays membership change events to the
+:class:`.CollectionAttributeImpl` that is currently managing the collection.
+The decorators observe function call arguments and return values, tracking
+entities entering or leaving the collection.  Two decorator approaches are
+provided.  One is a bundle of generic decorators that map function arguments
+and return values to events::
+
+  from sqlalchemy.orm.collections import collection
+  class MyClass(object):
+      # ...
+
+      @collection.adds(1)
+      def store(self, item):
+          self.data.append(item)
+
+      @collection.removes_return()
+      def pop(self):
+          return self.data.pop()
+
+
+The second approach is a bundle of targeted decorators that wrap appropriate
+append and remove notifiers around the mutation methods present in the
+standard Python ``list``, ``set`` and ``dict`` interfaces.  These could be
+specified in terms of generic decorator recipes, but are instead hand-tooled
+for increased efficiency.  The targeted decorators occasionally implement
+adapter-like behavior, such as mapping bulk-set methods (``extend``,
+``update``, ``__setslice__``, etc.) into the series of atomic mutation events
+that the ORM requires.
+
+The targeted decorators are used internally for automatic instrumentation of
+entity collection classes.  Every collection class goes through a
+transformation process roughly like so:
+
+1. If the class is a built-in, substitute a trivial sub-class
+2. Is this class already instrumented?
+3. Add in generic decorators
+4. Sniff out the collection interface through duck-typing
+5. Add targeted decoration to any undecorated interface method
+
+This process modifies the class at runtime, decorating methods and adding some
+bookkeeping properties.  This isn't possible (or desirable) for built-in
+classes like ``list``, so trivial sub-classes are substituted to hold
+decoration::
+
+  class InstrumentedList(list):
+      pass
+
+Collection classes can be specified in ``relationship(collection_class=)`` as
+types or a function that returns an instance.  Collection classes are
+inspected and instrumented during the mapper compilation phase.  The
+collection_class callable will be executed once to produce a specimen
+instance, and the type of that specimen will be instrumented.  Functions that
+return built-in types like ``lists`` will be adapted to produce instrumented
+instances.
+
+When extending a known type like ``list``, additional decorations are not
+generally not needed.  Odds are, the extension method will delegate to a
+method that's already instrumented.  For example::
+
+  class QueueIsh(list):
+     def push(self, item):
+         self.append(item)
+     def shift(self):
+         return self.pop(0)
+
+There's no need to decorate these methods.  ``append`` and ``pop`` are already
+instrumented as part of the ``list`` interface.  Decorating them would fire
+duplicate events, which should be avoided.
+
+The targeted decoration tries not to rely on other methods in the underlying
+collection class, but some are unavoidable.  Many depend on 'read' methods
+being present to properly instrument a 'write', for example, ``__setitem__``
+needs ``__getitem__``.  "Bulk" methods like ``update`` and ``extend`` may also
+reimplemented in terms of atomic appends and removes, so the ``extend``
+decoration will actually perform many ``append`` operations and not call the
+underlying method at all.
+
+Tight control over bulk operation and the firing of events is also possible by
+implementing the instrumentation internally in your methods.  The basic
+instrumentation package works under the general assumption that collection
+mutation will not raise unusual exceptions.  If you want to closely
+orchestrate append and remove events with exception management, internal
+instrumentation may be the answer.  Within your method,
+``collection_adapter(self)`` will retrieve an object that you can use for
+explicit control over triggering append and remove events.
+
+The owning object and :class:`.CollectionAttributeImpl` are also reachable
+through the adapter, allowing for some very sophisticated behavior.

+       :class:`.MapperEvents`.
+
+    New extension classes subclass :class:`.MapperExtension` and are specified
+    using the ``extension`` mapper() argument, which is a single
+    :class:`.MapperExtension` or a list of such::
+
+        from sqlalchemy.orm.interfaces import MapperExtension
+
+        class MyExtension(MapperExtension):
+            def before_insert(self, mapper, connection, instance):
+                print "instance %s before insert !" % instance
+
+        m = mapper(User, users_table, extension=MyExtension())
+
+    A single mapper can maintain a chain of ``MapperExtension``
+    objects. When a particular mapping event occurs, the
+    corresponding method on each ``MapperExtension`` is invoked
+    serially, and each method has the ability to halt the chain
+    from proceeding further::
+
+        m = mapper(User, users_table, extension=[ext1, ext2, ext3])
+
+    Each ``MapperExtension`` method returns the symbol
+    EXT_CONTINUE by default.   This symbol generally means "move
+    to the next ``MapperExtension`` for processing".  For methods
+    that return objects like translated rows or new object
+    instances, EXT_CONTINUE means the result of the method
+    should be ignored.   In some cases it's required for a
+    default mapper activity to be performed, such as adding a
+    new instance to a result list.
+
+    The symbol EXT_STOP has significance within a chain
+    of ``MapperExtension`` objects that the chain will be stopped
+    when this symbol is returned.  Like EXT_CONTINUE, it also
+    has additional significance in some cases that a default
+    mapper activity will not be performed.

+"""Defines SQLAlchemy's system of class instrumentation.
+
+This module is usually not directly visible to user applications, but
+defines a large part of the ORM's interactivity.
+
+instrumentation.py deals with registration of end-user classes
+for state tracking.   It interacts closely with state.py
+and attributes.py which establish per-instance and per-class-attribute
+instrumentation, respectively.
+
+The class instrumentation system can be customized on a per-class
+or global basis using the :mod:`sqlalchemy.ext.instrumentation`
+module, which provides the means to build and specify
+alternate instrumentation forms.
+
+.. versionchanged: 0.8
+   The instrumentation extension system was moved out of the
+   ORM and into the external :mod:`sqlalchemy.ext.instrumentation`
+   package.  When that package is imported, it installs
+   itself within sqlalchemy.orm so that its more comprehensive
+   resolution mechanics take effect.

+
+        :param class\_: The class to be mapped.  When using Declarative,
+          this argument is automatically passed as the declared class
+          itself.
+
+        :param local_table: The :class:`.Table` or other selectable
+           to which the class is mapped.  May be ``None`` if
+           this mapper inherits from another mapper using single-table
+           inheritance.   When using Declarative, this argument is
+           automatically passed by the extension, based on what
+           is configured via the ``__table__`` argument or via the
+           :class:`.Table` produced as a result of the ``__tablename__``
+           and :class:`.Column` arguments present.
+
+        :param always_refresh: If True, all query operations for this mapped
+           class will overwrite all data within object instances that already
+           exist within the session, erasing any in-memory changes with
+           whatever information was loaded from the database. Usage of this
+           flag is highly discouraged; as an alternative, see the method
+           :meth:`.Query.populate_existing`.
+
+        :param allow_partial_pks: Defaults to True.  Indicates that a
+           composite primary key with some NULL values should be considered as
+           possibly existing within the database. This affects whether a
+           mapper will assign an incoming row to an existing identity, as well
+           as if :meth:`.Session.merge` will check the database first for a
+           particular primary key value. A "partial primary key" can occur if
+           one has mapped to an OUTER JOIN, for example.
+
+        :param batch: Defaults to ``True``, indicating that save operations
+           of multiple entities can be batched together for efficiency.
+           Setting to False indicates
+           that an instance will be fully saved before saving the next
+           instance.  This is used in the extremely rare case that a
+           :class:`.MapperEvents` listener requires being called
+           in between individual row persistence operations.
+
+        :param column_prefix: A string which will be prepended
+           to the mapped attribute name when :class:`.Column`
+           objects are automatically assigned as attributes to the
+           mapped class.  Does not affect explicitly specified
+           column-based properties.
+
+           See the section :ref:`column_prefix` for an example.
+
+        :param concrete: If True, indicates this mapper should use concrete
+           table inheritance with its parent mapper.
+
+           See the section :ref:`concrete_inheritance` for an example.
+
+        :param confirm_deleted_rows: defaults to True; when a DELETE occurs
+          of one more rows based on specific primary keys, a warning is
+          emitted when the number of rows matched does not equal the number
+          of rows expected.  This parameter may be set to False to handle the
+          case where database ON DELETE CASCADE rules may be deleting some of
+          those rows automatically.  The warning may be changed to an
+          exception in a future release.
+
+          .. versionadded:: 0.9.4 - added
+             :paramref:`.mapper.confirm_deleted_rows` as well as conditional
+             matched row checking on delete.
+
+        :param eager_defaults: if True, the ORM will immediately fetch the
+          value of server-generated default values after an INSERT or UPDATE,
+          rather than leaving them as expired to be fetched on next access.
+          This can be used for event schemes where the server-generated values
+          are needed immediately before the flush completes.   By default,
+          this scheme will emit an individual ``SELECT`` statement per row
+          inserted or updated, which note can add significant performance
+          overhead.  However, if the
+          target database supports :term:`RETURNING`, the default values will
+          be returned inline with the INSERT or UPDATE statement, which can
+          greatly enhance performance for an application that needs frequent
+          access to just-generated server defaults.
+
+          .. versionchanged:: 0.9.0 The ``eager_defaults`` option can now
+             make use of :term:`RETURNING` for backends which support it.
+
+        :param exclude_properties: A list or set of string column names to
+          be excluded from mapping.
+
+          See :ref:`include_exclude_cols` for an example.
+
+        :param extension: A :class:`.MapperExtension` instance or
+           list of :class:`.MapperExtension` instances which will be applied
+           to all operations by this :class:`.Mapper`.  **Deprecated.**
+           Please see :class:`.MapperEvents`.
+
+        :param include_properties: An inclusive list or set of string column
+          names to map.
+
+          See :ref:`include_exclude_cols` for an example.
+
+        :param inherits: A mapped class or the corresponding :class:`.Mapper`
+          of one indicating a superclass to which this :class:`.Mapper`
+          should *inherit* from.   The mapped class here must be a subclass
+          of the other mapper's class.   When using Declarative, this argument
+          is passed automatically as a result of the natural class
+          hierarchy of the declared classes.
+
+          .. seealso::
+
+            :ref:`inheritance_toplevel`
+
+        :param inherit_condition: For joined table inheritance, a SQL
+           expression which will
+           define how the two tables are joined; defaults to a natural join
+           between the two tables.
+
+        :param inherit_foreign_keys: When ``inherit_condition`` is used and
+           the columns present are missing a :class:`.ForeignKey`
+           configuration, this parameter can be used to specify which columns
+           are "foreign".  In most cases can be left as ``None``.
+
+        :param legacy_is_orphan: Boolean, defaults to ``False``.
+          When ``True``, specifies that "legacy" orphan consideration
+          is to be applied to objects mapped by this mapper, which means
+          that a pending (that is, not persistent) object is auto-expunged
+          from an owning :class:`.Session` only when it is de-associated
+          from *all* parents that specify a ``delete-orphan`` cascade towards
+          this mapper.  The new default behavior is that the object is
+          auto-expunged when it is de-associated with *any* of its parents
+          that specify ``delete-orphan`` cascade.  This behavior is more
+          consistent with that of a persistent object, and allows behavior to
+          be consistent in more scenarios independently of whether or not an
+          orphanable object has been flushed yet or not.
+
+          See the change note and example at :ref:`legacy_is_orphan_addition`
+          for more detail on this change.
+
+          .. versionadded:: 0.8 - the consideration of a pending object as
+            an "orphan" has been modified to more closely match the
+            behavior as that of persistent objects, which is that the object
+            is expunged from the :class:`.Session` as soon as it is
+            de-associated from any of its orphan-enabled parents.  Previously,
+            the pending object would be expunged only if de-associated
+            from all of its orphan-enabled parents. The new flag
+            ``legacy_is_orphan`` is added to :func:`.orm.mapper` which
+            re-establishes the legacy behavior.
+
+        :param non_primary: Specify that this :class:`.Mapper` is in addition
+          to the "primary" mapper, that is, the one used for persistence.
+          The :class:`.Mapper` created here may be used for ad-hoc
+          mapping of the class to an alternate selectable, for loading
+          only.
+
+          :paramref:`.Mapper.non_primary` is not an often used option, but
+          is useful in some specific :func:`.relationship` cases.
+
+          .. seealso::
+
+              :ref:`relationship_non_primary_mapper`
+
+        :param order_by: A single :class:`.Column` or list of :class:`.Column`
+           objects for which selection operations should use as the default
+           ordering for entities.  By default mappers have no pre-defined
+           ordering.
+
+        :param passive_updates: Indicates UPDATE behavior of foreign key
+           columns when a primary key column changes on a joined-table
+           inheritance mapping.   Defaults to ``True``.
+
+           When True, it is assumed that ON UPDATE CASCADE is configured on
+           the foreign key in the database, and that the database will handle
+           propagation of an UPDATE from a source column to dependent columns
+           on joined-table rows.
+
+           When False, it is assumed that the database does not enforce
+           referential integrity and will not be issuing its own CASCADE
+           operation for an update.  The unit of work process will
+           emit an UPDATE statement for the dependent columns during a
+           primary key change.

+
+        :param polymorphic_on: Specifies the column, attribute, or
+          SQL expression used to determine the target class for an
+          incoming row, when inheriting classes are present.
+
+          This value is commonly a :class:`.Column` object that's
+          present in the mapped :class:`.Table`::
+
+            class Employee(Base):
+                __tablename__ = 'employee'
+
+                id = Column(Integer, primary_key=True)
+                discriminator = Column(String(50))
+
+                __mapper_args__ = {
+                    "polymorphic_on":discriminator,
+                    "polymorphic_identity":"employee"
+                }
+
+          It may also be specified
+          as a SQL expression, as in this example where we
+          use the :func:`.case` construct to provide a conditional
+          approach::
+
+            class Employee(Base):
+                __tablename__ = 'employee'
+
+                id = Column(Integer, primary_key=True)
+                discriminator = Column(String(50))
+
+                __mapper_args__ = {
+                    "polymorphic_on":case([
+                        (discriminator == "EN", "engineer"),
+                        (discriminator == "MA", "manager"),
+                    ], else_="employee"),
+                    "polymorphic_identity":"employee"
+                }
+
+          It may also refer to any attribute
+          configured with :func:`.column_property`, or to the
+          string name of one::
+
+                class Employee(Base):
+                    __tablename__ = 'employee'
+
+                    id = Column(Integer, primary_key=True)
+                    discriminator = Column(String(50))
+                    employee_type = column_property(
+                        case([
+                            (discriminator == "EN", "engineer"),
+                            (discriminator == "MA", "manager"),
+                        ], else_="employee")
+                    )
+
+                    __mapper_args__ = {
+                        "polymorphic_on":employee_type,
+                        "polymorphic_identity":"employee"
+                    }
+
+          .. versionchanged:: 0.7.4
+              ``polymorphic_on`` may be specified as a SQL expression,
+              or refer to any attribute configured with
+              :func:`.column_property`, or to the string name of one.
+
+          When setting ``polymorphic_on`` to reference an
+          attribute or expression that's not present in the
+          locally mapped :class:`.Table`, yet the value
+          of the discriminator should be persisted to the database,
+          the value of the
+          discriminator is not automatically set on new
+          instances; this must be handled by the user,
+          either through manual means or via event listeners.
+          A typical approach to establishing such a listener
+          looks like::
+
+                from sqlalchemy import event
+                from sqlalchemy.orm import object_mapper
+
+                @event.listens_for(Employee, "init", propagate=True)
+                def set_identity(instance, *arg, **kw):
+                    mapper = object_mapper(instance)
+                    instance.discriminator = mapper.polymorphic_identity
+
+          Where above, we assign the value of ``polymorphic_identity``
+          for the mapped class to the ``discriminator`` attribute,
+          thus persisting the value to the ``discriminator`` column
+          in the database.
+
+          .. seealso::
+
+            :ref:`inheritance_toplevel`
+
+        :param polymorphic_identity: Specifies the value which
+          identifies this particular class as returned by the
+          column expression referred to by the ``polymorphic_on``
+          setting.  As rows are received, the value corresponding
+          to the ``polymorphic_on`` column expression is compared
+          to this value, indicating which subclass should
+          be used for the newly reconstructed object.
+
+        :param properties: A dictionary mapping the string names of object
+           attributes to :class:`.MapperProperty` instances, which define the
+           persistence behavior of that attribute.  Note that :class:`.Column`
+           objects present in
+           the mapped :class:`.Table` are automatically placed into
+           ``ColumnProperty`` instances upon mapping, unless overridden.
+           When using Declarative, this argument is passed automatically,
+           based on all those :class:`.MapperProperty` instances declared
+           in the declared class body.
+
+        :param primary_key: A list of :class:`.Column` objects which define
+           the primary key to be used against this mapper's selectable unit.
+           This is normally simply the primary key of the ``local_table``, but
+           can be overridden here.
+
+        :param version_id_col: A :class:`.Column`
+           that will be used to keep a running version id of rows
+           in the table.  This is used to detect concurrent updates or
+           the presence of stale data in a flush.  The methodology is to
+           detect if an UPDATE statement does not match the last known
+           version id, a
+           :class:`~sqlalchemy.orm.exc.StaleDataError` exception is
+           thrown.
+           By default, the column must be of :class:`.Integer` type,
+           unless ``version_id_generator`` specifies an alternative version
+           generator.

+              and rationale.
+
+        :param version_id_generator: Define how new version ids should
+          be generated.  Defaults to ``None``, which indicates that
+          a simple integer counting scheme be employed.  To provide a custom
+          versioning scheme, provide a callable function of the form::
+
+              def generate_version(version):
+                  return next_version
+
+          Alternatively, server-side versioning functions such as triggers,
+          or programmatic versioning schemes outside of the version id
+          generator may be used, by specifying the value ``False``.
+          Please see :ref:`server_side_version_counter` for a discussion
+          of important points when using this option.

+            loading, that is, which tables are queried at once. <classes> is

+            flush, that is, has any kind of "dirty" state within a flush.
+            Setting this parameter to ``False`` will have the effect of

+
+        **Simple Relationship Joins**
+
+        Consider a mapping between two classes ``User`` and ``Address``,
+        with a relationship ``User.addresses`` representing a collection
+        of ``Address`` objects associated with each ``User``.   The most
+        common usage of :meth:`~.Query.join` is to create a JOIN along this
+        relationship, using the ``User.addresses`` attribute as an indicator
+        for how this should occur::
+
+            q = session.query(User).join(User.addresses)
+
+        Where above, the call to :meth:`~.Query.join` along ``User.addresses``
+        will result in SQL equivalent to::
+
+            SELECT user.* FROM user JOIN address ON user.id = address.user_id
+
+        In the above example we refer to ``User.addresses`` as passed to
+        :meth:`~.Query.join` as the *on clause*, that is, it indicates
+        how the "ON" portion of the JOIN should be constructed.  For a
+        single-entity query such as the one above (i.e. we start by selecting
+        only from ``User`` and nothing else), the relationship can also be
+        specified by its string name::
+
+            q = session.query(User).join("addresses")
+
+        :meth:`~.Query.join` can also accommodate multiple
+        "on clause" arguments to produce a chain of joins, such as below
+        where a join across four related entities is constructed::
+
+            q = session.query(User).join("orders", "items", "keywords")
+
+        The above would be shorthand for three separate calls to
+        :meth:`~.Query.join`, each using an explicit attribute to indicate
+        the source entity::
+
+            q = session.query(User).\\
+                    join(User.orders).\\
+                    join(Order.items).\\
+                    join(Item.keywords)
+
+        **Joins to a Target Entity or Selectable**
+
+        A second form of :meth:`~.Query.join` allows any mapped entity
+        or core selectable construct as a target.   In this usage,
+        :meth:`~.Query.join` will attempt
+        to create a JOIN along the natural foreign key relationship between
+        two entities::
+
+            q = session.query(User).join(Address)
+
+        The above calling form of :meth:`~.Query.join` will raise an error if
+        either there are no foreign keys between the two entities, or if
+        there are multiple foreign key linkages between them.   In the
+        above calling form, :meth:`~.Query.join` is called upon to
+        create the "on clause" automatically for us.  The target can
+        be any mapped entity or selectable, such as a :class:`.Table`::
+
+            q = session.query(User).join(addresses_table)
+
+        **Joins to a Target with an ON Clause**
+
+        The third calling form allows both the target entity as well
+        as the ON clause to be passed explicitly.   Suppose for
+        example we wanted to join to ``Address`` twice, using
+        an alias the second time.  We use :func:`~sqlalchemy.orm.aliased`
+        to create a distinct alias of ``Address``, and join
+        to it using the ``target, onclause`` form, so that the
+        alias can be specified explicitly as the target along with
+        the relationship to instruct how the ON clause should proceed::
+
+            a_alias = aliased(Address)
+
+            q = session.query(User).\\
+                    join(User.addresses).\\
+                    join(a_alias, User.addresses).\\
+                    filter(Address.email_address=='ed@foo.com').\\
+                    filter(a_alias.email_address=='ed@bar.com')
+
+        Where above, the generated SQL would be similar to::
+
+            SELECT user.* FROM user
+                JOIN address ON user.id = address.user_id
+                JOIN address AS address_1 ON user.id=address_1.user_id
+                WHERE address.email_address = :email_address_1
+                AND address_1.email_address = :email_address_2
+
+        The two-argument calling form of :meth:`~.Query.join`
+        also allows us to construct arbitrary joins with SQL-oriented
+        "on clause" expressions, not relying upon configured relationships
+        at all.  Any SQL expression can be passed as the ON clause
+        when using the two-argument form, which should refer to the target
+        entity in some way as well as an applicable source entity::
+
+            q = session.query(User).join(Address, User.id==Address.user_id)
+
+        .. versionchanged:: 0.7
+            In SQLAlchemy 0.6 and earlier, the two argument form of
+            :meth:`~.Query.join` requires the usage of a tuple:
+            ``query(User).join((Address, User.id==Address.user_id))``\ .
+            This calling form is accepted in 0.7 and further, though
+            is not necessary unless multiple join conditions are passed to
+            a single :meth:`~.Query.join` call, which itself is also not
+            generally necessary as it is now equivalent to multiple
+            calls (this wasn't always the case).
+
+        **Advanced Join Targeting and Adaption**
+
+        There is a lot of flexibility in what the "target" can be when using
+        :meth:`~.Query.join`.   As noted previously, it also accepts
+        :class:`.Table` constructs and other selectables such as
+        :func:`.alias` and :func:`.select` constructs, with either the one
+        or two-argument forms::
+
+            addresses_q = select([Address.user_id]).\\
+                        where(Address.email_address.endswith("@bar.com")).\\
+                        alias()
+
+            q = session.query(User).\\
+                        join(addresses_q, addresses_q.c.user_id==User.id)
+
+        :meth:`~.Query.join` also features the ability to *adapt* a
+        :meth:`~sqlalchemy.orm.relationship` -driven ON clause to the target
+        selectable. Below we construct a JOIN from ``User`` to a subquery
+        against ``Address``, allowing the relationship denoted by
+        ``User.addresses`` to *adapt* itself to the altered target::
+
+            address_subq = session.query(Address).\\
+                            filter(Address.email_address == 'ed@foo.com').\\
+                            subquery()
+
+            q = session.query(User).join(address_subq, User.addresses)
+
+        Producing SQL similar to::
+
+            SELECT user.* FROM user
+                JOIN (
+                    SELECT address.id AS id,
+                            address.user_id AS user_id,
+                            address.email_address AS email_address
+                    FROM address
+                    WHERE address.email_address = :email_address_1
+                ) AS anon_1 ON user.id = anon_1.user_id
+
+        The above form allows one to fall back onto an explicit ON
+        clause at any time::
+
+            q = session.query(User).\\
+                    join(address_subq, User.id==address_subq.c.user_id)
+
+        **Controlling what to Join From**
+
+        While :meth:`~.Query.join` exclusively deals with the "right"
+        side of the JOIN, we can also control the "left" side, in those
+        cases where it's needed, using :meth:`~.Query.select_from`.
+        Below we construct a query against ``Address`` but can still
+        make usage of ``User.addresses`` as our ON clause by instructing
+        the :class:`.Query` to select first from the ``User``
+        entity::
+
+            q = session.query(Address).select_from(User).\\
+                            join(User.addresses).\\
+                            filter(User.name == 'ed')
+
+        Which will produce SQL similar to::
+
+            SELECT address.* FROM user
+                JOIN address ON user.id=address.user_id
+                WHERE user.name = :name_1
+
+        **Constructing Aliases Anonymously**
+
+        :meth:`~.Query.join` can construct anonymous aliases
+        using the ``aliased=True`` flag.  This feature is useful
+        when a query is being joined algorithmically, such as
+        when querying self-referentially to an arbitrary depth::
+
+            q = session.query(Node).\\
+                    join("children", "children", aliased=True)
+
+        When ``aliased=True`` is used, the actual "alias" construct
+        is not explicitly available.  To work with it, methods such as
+        :meth:`.Query.filter` will adapt the incoming entity to
+        the last join point::
+
+            q = session.query(Node).\\
+                    join("children", "children", aliased=True).\\
+                    filter(Node.name == 'grandchild 1')
+
+        When using automatic aliasing, the ``from_joinpoint=True``
+        argument can allow a multi-node join to be broken into
+        multiple calls to :meth:`~.Query.join`, so that
+        each path along the way can be further filtered::
+
+            q = session.query(Node).\\
+                    join("children", aliased=True).\\
+                    filter(Node.name='child 1').\\
+                    join("children", aliased=True, from_joinpoint=True).\\
+                    filter(Node.name == 'grandchild 1')
+
+        The filtering aliases above can then be reset back to the
+        original ``Node`` entity using :meth:`~.Query.reset_joinpoint`::
+
+            q = session.query(Node).\\
+                    join("children", "children", aliased=True).\\
+                    filter(Node.name == 'grandchild 1').\\
+                    reset_joinpoint().\\
+                    filter(Node.name == 'parent 1)
+
+        For an example of ``aliased=True``, see the distribution
+        example :ref:`examples_xmlpersistence` which illustrates
+        an XPath-like query system using algorithmic joins.
+
+        :param \*props: A collection of one or more join conditions,
+         each consisting of a relationship-bound attribute or string
+         relationship name representing an "on clause", or a single
+         target entity, or a tuple in the form of ``(target, onclause)``.
+         A special two-argument calling form of the form ``target, onclause``
+         is also accepted.
+        :param aliased=False: If True, indicate that the JOIN target should be
+         anonymously aliased.  Subsequent calls to :meth:`~.Query.filter`
+         and similar will adapt the incoming criterion to the target
+         alias, until :meth:`~.Query.reset_joinpoint` is called.
+        :param from_joinpoint=False: When using ``aliased=True``, a setting
+         of True here will cause the join to be from the most recent
+         joined target, rather than starting back from the original
+         FROM clauses of the query.

+
+        This method is similar to the :meth:`.Query.select_from`
+        method, in that it sets the FROM clause of the query.  However,
+        where :meth:`.Query.select_from` only affects what is placed
+        in the FROM, this method also applies the given selectable
+        to replace the FROM which the selected entities would normally
+        select from.
+
+        The given ``from_obj`` must be an instance of a :class:`.FromClause`,
+        e.g. a :func:`.select` or :class:`.Alias` construct.
+
+        An example would be a :class:`.Query` that selects ``User`` entities,
+        but uses :meth:`.Query.select_entity_from` to have the entities
+        selected from a :func:`.select` construct instead of the
+        base ``user`` table::
+
+            select_stmt = select([User]).where(User.id == 7)
+
+            q = session.query(User).\\
+                    select_entity_from(select_stmt).\\
+                    filter(User.name == 'ed')
+
+        The query generated will select ``User`` entities directly
+        from the given :func:`.select` construct, and will be::
+
+            SELECT anon_1.id AS anon_1_id, anon_1.name AS anon_1_name
+            FROM (SELECT "user".id AS id, "user".name AS name
+            FROM "user"
+            WHERE "user".id = :id_1) AS anon_1
+            WHERE anon_1.name = :name_1
+
+        Notice above that even the WHERE criterion was "adapted" such that
+        the ``anon_1`` subquery effectively replaces all references to the
+        ``user`` table, except for the one that it refers to internally.
+
+        Compare this to :meth:`.Query.select_from`, which as of
+        version 0.9, does not affect existing entities.  The
+        statement below::
+
+            q = session.query(User).\\
+                    select_from(select_stmt).\\
+                    filter(User.name == 'ed')
+
+        Produces SQL where both the ``user`` table as well as the
+        ``select_stmt`` construct are present as separate elements
+        in the FROM clause.  No "adaptation" of the ``user`` table
+        is applied::
+
+            SELECT "user".id AS user_id, "user".name AS user_name
+            FROM "user", (SELECT "user".id AS id, "user".name AS name
+            FROM "user"
+            WHERE "user".id = :id_1) AS anon_1
+            WHERE "user".name = :name_1
+
+        :meth:`.Query.select_entity_from` maintains an older
+        behavior of :meth:`.Query.select_from`.  In modern usage,
+        similar results can also be achieved using :func:`.aliased`::
+
+            select_stmt = select([User]).where(User.id == 7)
+            user_from_select = aliased(User, select_stmt.alias())
+
+            q = session.query(user_from_select)
+
+        :param from_obj: a :class:`.FromClause` object that will replace

+        The constructed class is an instance of

+
+        A typical :func:`.relationship`, used in a classical mapping::
+
+           mapper(Parent, properties={
+             'children': relationship(Child)
+           })
+
+        Some arguments accepted by :func:`.relationship` optionally accept a
+        callable function, which when called produces the desired value.
+        The callable is invoked by the parent :class:`.Mapper` at "mapper
+        initialization" time, which happens only when mappers are first used,
+        and is assumed to be after all mappings have been constructed.  This
+        can be used to resolve order-of-declaration and other dependency
+        issues, such as if ``Child`` is declared below ``Parent`` in the same
+        file::
+
+            mapper(Parent, properties={
+                "children":relationship(lambda: Child,

+
+        When using the :ref:`declarative_toplevel` extension, the Declarative
+        initializer allows string arguments to be passed to
+        :func:`.relationship`.  These string arguments are converted into
+        callables that evaluate the string as Python code, using the
+        Declarative class-registry as a namespace.  This allows the lookup of
+        related classes to be automatic via their string name, and removes the
+        need to import related classes at all into the local module space::
+
+            from sqlalchemy.ext.declarative import declarative_base
+
+            Base = declarative_base()
+
+            class Parent(Base):

+
+        :param argument:
+          a mapped class, or actual :class:`.Mapper` instance, representing
+          the target of the relationship.
+
+          :paramref:`~.relationship.argument` may also be passed as a callable
+          function which is evaluated at mapper initialization time, and may
+          be passed as a Python-evaluable string when using Declarative.
+
+          .. seealso::
+
+            :ref:`declarative_configuring_relationships` - further detail
+            on relationship configuration when using Declarative.
+
+        :param secondary:
+          for a many-to-many relationship, specifies the intermediary
+          table, and is typically an instance of :class:`.Table`.
+          In less common circumstances, the argument may also be specified
+          as an :class:`.Alias` construct, or even a :class:`.Join` construct.
+
+          :paramref:`~.relationship.secondary` may
+          also be passed as a callable function which is evaluated at
+          mapper initialization time.  When using Declarative, it may also
+          be a string argument noting the name of a :class:`.Table` that is
+          present in the :class:`.MetaData` collection associated with the
+          parent-mapped :class:`.Table`.
+
+          The :paramref:`~.relationship.secondary` keyword argument is
+          typically applied in the case where the intermediary :class:`.Table`
+          is not otherwise exprssed in any direct class mapping. If the
+          "secondary" table is also explicitly mapped elsewhere (e.g. as in
+          :ref:`association_pattern`), one should consider applying the
+          :paramref:`~.relationship.viewonly` flag so that this
+          :func:`.relationship` is not used for persistence operations which

+          When set to ``True``, the DISTINCT keyword is applied to the

+
+          It may be desirable to set this flag to False when the DISTINCT is

+
+        :param foreign_keys:
+
+          a list of columns which are to be used as "foreign key"
+          columns, or columns which refer to the value in a remote
+          column, within the context of this :func:`.relationship`
+          object's :paramref:`~.relationship.primaryjoin` condition.
+          That is, if the :paramref:`~.relationship.primaryjoin`
+          condition of this :func:`.relationship` is ``a.id ==
+          b.a_id``, and the values in ``b.a_id`` are required to be
+          present in ``a.id``, then the "foreign key" column of this
+          :func:`.relationship` is ``b.a_id``.
+
+          In normal cases, the :paramref:`~.relationship.foreign_keys`
+          parameter is **not required.** :func:`.relationship` will
+          automatically determine which columns in the
+          :paramref:`~.relationship.primaryjoin` conditition are to be
+          considered "foreign key" columns based on those
+          :class:`.Column` objects that specify :class:`.ForeignKey`,
+          or are otherwise listed as referencing columns in a
+          :class:`.ForeignKeyConstraint` construct.
+          :paramref:`~.relationship.foreign_keys` is only needed when:
+
+            1. There is more than one way to construct a join from the local
+               table to the remote table, as there are multiple foreign key
+               references present.  Setting ``foreign_keys`` will limit the
+               :func:`.relationship` to consider just those columns specified
+               here as "foreign".
+
+               .. versionchanged:: 0.8
+                    A multiple-foreign key join ambiguity can be resolved by
+                    setting the :paramref:`~.relationship.foreign_keys`
+                    parameter alone, without the need to explicitly set
+                    :paramref:`~.relationship.primaryjoin` as well.
+
+            2. The :class:`.Table` being mapped does not actually have
+               :class:`.ForeignKey` or :class:`.ForeignKeyConstraint`
+               constructs present, often because the table
+               was reflected from a database that does not support foreign key
+               reflection (MySQL MyISAM).
+
+            3. The :paramref:`~.relationship.primaryjoin` argument is used to
+               construct a non-standard join condition, which makes use of
+               columns or expressions that do not normally refer to their
+               "parent" column, such as a join condition expressed by a
+               complex comparison using a SQL function.
+
+          The :func:`.relationship` construct will raise informative
+          error messages that suggest the use of the
+          :paramref:`~.relationship.foreign_keys` parameter when
+          presented with an ambiguous condition.   In typical cases,
+          if :func:`.relationship` doesn't raise any exceptions, the
+          :paramref:`~.relationship.foreign_keys` parameter is usually
+          not needed.
+
+          :paramref:`~.relationship.foreign_keys` may also be passed as a
+          callable function which is evaluated at mapper initialization time,
+          and may be passed as a Python-evaluable string when using

+              expression, which is an alternate, more specific system of
+              describing which columns in a particular
+              :paramref:`~.relationship.primaryjoin` should be considered
+              "foreign".

+
+        :param innerjoin=False:
+          when ``True``, joined eager loads will use an inner join to join
+          against related tables instead of an outer join.  The purpose
+          of this option is generally one of performance, as inner joins
+          generally perform better than outer joins.
+
+          This flag can be set to ``True`` when the relationship references an
+          object via many-to-one using local foreign keys that are not
+          nullable, or when the reference is one-to-one or a collection that
+          is guaranteed to have one or at least one entry.
+
+          If the joined-eager load is chained onto an existing LEFT OUTER
+          JOIN, ``innerjoin=True`` will be bypassed and the join will continue
+          to chain as LEFT OUTER JOIN so that the results don't change.  As an
+          alternative, specify the value ``"nested"``.  This will instead nest
+          the join on the right side, e.g. using the form "a LEFT OUTER JOIN
+          (b JOIN c)".

+          relationship.  The number counts how many times the same Mapper
+          shall be present in the loading condition along a particular join
+          branch.  When left at its default of ``None``, eager loaders
+          will stop chaining when they encounter a the same target mapper
+          which is already higher up in the chain.  This option applies

+
+        :param lazy='select': specifies
+          how the related items should be loaded.  Default value is
+          ``select``.  Values include:
+
+          * ``select`` - items should be loaded lazily when the property is
+            first accessed, using a separate SELECT statement, or identity map
+            fetch for simple many-to-one references.
+
+          * ``immediate`` - items should be loaded as the parents are loaded,
+            using a separate SELECT statement, or identity map fetch for
+            simple many-to-one references.
+
+          * ``joined`` - items should be loaded "eagerly" in the same query as
+            that of the parent, using a JOIN or LEFT OUTER JOIN.  Whether
+            the join is "outer" or not is determined by the
+            :paramref:`~.relationship.innerjoin` parameter.
+
+          * ``subquery`` - items should be loaded "eagerly" as the parents are
+            loaded, using one additional SQL statement, which issues a JOIN to
+            a subquery of the original statement, for each collection
+            requested.
+
+          * ``noload`` - no loading should occur at any time.  This is to
+            support "write-only" attributes, or attributes which are
+            populated in some manner specific to the application.
+
+          * ``dynamic`` - the attribute will return a pre-configured
+            :class:`.Query` object for all read
+            operations, onto which further filtering operations can be
+            applied before iterating the results.  See

+
+        :param load_on_pending=False:
+          Indicates loading behavior for transient or pending parent objects.
+
+          When set to ``True``, causes the lazy-loader to
+          issue a query for a parent object that is not persistent, meaning it
+          has never been flushed.  This may take effect for a pending object
+          when autoflush is disabled, or for a transient object that has been
+          "attached" to a :class:`.Session` but is not part of its pending
+          collection.
+
+          The :paramref:`~.relationship.load_on_pending` flag does not improve
+          behavior when the ORM is used normally - object references should be
+          constructed at the object level, not at the foreign key level, so
+          that they are present in an ordinary way before a flush proceeds.
+          This flag is not not intended for general use.

+          .. seealso::
+
+              :meth:`.Session.enable_relationship_loading` - this method
+              establishes "load on pending" behavior for the whole object, and
+              also allows loading on objects that remain transient or
+              detached.
+
+        :param order_by:
+          indicates the ordering that should be applied when loading these
+          items.  :paramref:`~.relationship.order_by` is expected to refer to
+          one of the :class:`.Column` objects to which the target class is
+          mapped, or the attribute itself bound to the target class which
+          refers to the column.
+
+          :paramref:`~.relationship.order_by` may also be passed as a callable
+          function which is evaluated at mapper initialization time, and may
+          be passed as a Python-evaluable string when using Declarative.
+
+        :param passive_deletes=False:
+           Indicates loading behavior during delete operations.
+
+           A value of True indicates that unloaded child items should not
+           be loaded during a delete operation on the parent.  Normally,
+           when a parent item is deleted, all child items are loaded so
+           that they can either be marked as deleted, or have their
+           foreign key to the parent set to NULL.  Marking this flag as
+           True usually implies an ON DELETE <CASCADE|SET NULL> rule is in
+           place which will handle updating/deleting child rows on the
+           database side.
+
+           Additionally, setting the flag to the string value 'all' will
+           disable the "nulling out" of the child foreign keys, when there
+           is no delete or delete-orphan cascade enabled.  This is
+           typically used when a triggering or error raise scenario is in
+           place on the database side.  Note that the foreign key
+           attributes on in-session child objects will not be changed
+           after a flush occurs so this is a very special use-case
+           setting.
+
+           .. seealso::
+
+                :ref:`passive_deletes` - Introductory documentation
+                and examples.
+
+        :param passive_updates=True:
+          Indicates loading and INSERT/UPDATE/DELETE behavior when the
+          source of a foreign key value changes (i.e. an "on update"
+          cascade), which are typically the primary key columns of the
+          source row.
+
+          When True, it is assumed that ON UPDATE CASCADE is configured on
+          the foreign key in the database, and that the database will
+          handle propagation of an UPDATE from a source column to
+          dependent rows.  Note that with databases which enforce
+          referential integrity (i.e. PostgreSQL, MySQL with InnoDB tables),
+          ON UPDATE CASCADE is required for this operation.  The
+          relationship() will update the value of the attribute on related
+          items which are locally present in the session during a flush.
+
+          When False, it is assumed that the database does not enforce
+          referential integrity and will not be issuing its own CASCADE
+          operation for an update.  The relationship() will issue the
+          appropriate UPDATE statements to the database in response to the
+          change of a referenced key, and items locally present in the
+          session during a flush will also be refreshed.
+
+          This flag should probably be set to False if primary key changes
+          are expected and the database in use doesn't support CASCADE
+          (i.e. SQLite, MySQL MyISAM tables).

+        :param post_update:
+          this indicates that the relationship should be handled by a
+          second UPDATE statement after an INSERT or before a
+          DELETE. Currently, it also will issue an UPDATE after the
+          instance was UPDATEd as well, although this technically should
+          be improved. This flag is used to handle saving bi-directional
+          dependencies between two individual rows (i.e. each row
+          references the other), where it would otherwise be impossible to
+          INSERT or DELETE both rows fully since one row exists before the
+          other. Use this flag when a particular mapping arrangement will
+          incur two rows that are dependent on each other, such as a table
+          that has a one-to-many relationship to a set of child rows, and
+          also has a column that references a single child row within that
+          list (i.e. both tables contain a foreign key to each other). If
+          a flush operation returns an error that a "cyclical
+          dependency" was detected, this is a cue that you might want to
+          use :paramref:`~.relationship.post_update` to "break" the cycle.

+          is, a relationship that specifies ``lazy="dynamic"`` or was

+        :param secondaryjoin:
+          a SQL expression that will be used as the join of

+          computed based on the foreign key relationships of the association
+          and child tables.
+
+          :paramref:`~.relationship.secondaryjoin` may also be passed as a

+          from being associated with more than one parent at a time.
+          This is used for many-to-one or many-to-many relationships that
+          should be treated either as one-to-one or one-to-many.  Its usage
+          is optional, except for :func:`.relationship` constructs which
+          are many-to-one or many-to-many and also
+          specify the ``delete-orphan`` cascade option.  The
+          :func:`.relationship` construct itself will raise an error
+          instructing when this option is required.

+
+        :param uselist:
+          a boolean that indicates if this property should be loaded as a
+          list or a scalar. In most cases, this value is determined
+          automatically by :func:`.relationship` at mapper configuration
+          time, based on the type and direction
+          of the relationship - one to many forms a list, many to one
+          forms a scalar, many to many is a list. If a scalar is desired
+          where normally a list would be present, such as a bi-directional
+          one-to-one relationship, set :paramref:`~.relationship.uselist` to
+          False.
+
+          The :paramref:`~.relationship.uselist` flag is also available on an
+          existing :func:`.relationship` construct as a read-only attribute,
+          which can be used to determine if this :func:`.relationship` deals

+              one" relationship pattern, which is typically when the
+              :paramref:`~.relationship.uselist` flag is needed.
+
+        :param viewonly=False:
+          when set to True, the relationship is used only for loading objects,
+          and not for any persistence operation.  A :func:`.relationship`
+          which specifies :paramref:`~.relationship.viewonly` can work
+          with a wider range of SQL operations within the

+          operations that feature the use of a variety of comparison operators
+          as well as SQL functions such as :func:`~.sql.expression.cast`.  The
+          :paramref:`~.relationship.viewonly` flag is also of general use when
+          defining any kind of :func:`~.relationship` that doesn't represent
+          the full set of related objects, to prevent modifications of the
+          collection from resulting in persistence operations.

+
+    :class:`.SessionTransaction` is a mostly behind-the-scenes object
+    not normally referenced directly by application code.   It coordinates
+    among multiple :class:`.Connection` objects, maintaining a database
+    transaction for each one individually, committing or rolling them
+    back all at once.   It also provides optional two-phase commit behavior
+    which can augment this coordination operation.
+
+    The :attr:`.Session.transaction` attribute of :class:`.Session`
+    refers to the current :class:`.SessionTransaction` object in use, if any.
+
+
+    A :class:`.SessionTransaction` is associated with a :class:`.Session`
+    in its default mode of ``autocommit=False`` immediately, associated
+    with no database connections.  As the :class:`.Session` is called upon
+    to emit SQL on behalf of various :class:`.Engine` or :class:`.Connection`
+    objects, a corresponding :class:`.Connection` and associated
+    :class:`.Transaction` is added to a collection within the
+    :class:`.SessionTransaction` object, becoming one of the
+    connection/transaction pairs maintained by the
+    :class:`.SessionTransaction`.
+
+    The lifespan of the :class:`.SessionTransaction` ends when the
+    :meth:`.Session.commit`, :meth:`.Session.rollback` or
+    :meth:`.Session.close` methods are called.  At this point, the
+    :class:`.SessionTransaction` removes its association with its parent
+    :class:`.Session`.   A :class:`.Session` that is in ``autocommit=False``
+    mode will create a new :class:`.SessionTransaction` to replace it
+    immediately, whereas a :class:`.Session` that's in ``autocommit=True``
+    mode will remain without a :class:`.SessionTransaction` until the
+    :meth:`.Session.begin` method is called.
+
+    Another detail of :class:`.SessionTransaction` behavior is that it is
+    capable of "nesting".  This means that the :meth:`.Session.begin` method
+    can be called while an existing :class:`.SessionTransaction` is already
+    present, producing a new :class:`.SessionTransaction` that temporarily
+    replaces the parent :class:`.SessionTransaction`.   When a
+    :class:`.SessionTransaction` is produced as nested, it assigns itself to
+    the :attr:`.Session.transaction` attribute.  When it is ended via
+    :meth:`.Session.commit` or :meth:`.Session.rollback`, it restores its
+    parent :class:`.SessionTransaction` back onto the
+    :attr:`.Session.transaction` attribute.  The behavior is effectively a
+    stack, where :attr:`.Session.transaction` refers to the current head of
+    the stack.
+
+    The purpose of this stack is to allow nesting of
+    :meth:`.Session.rollback` or :meth:`.Session.commit` calls in context
+    with various flavors of :meth:`.Session.begin`. This nesting behavior
+    applies to when :meth:`.Session.begin_nested` is used to emit a
+    SAVEPOINT transaction, and is also used to produce a so-called
+    "subtransaction" which allows a block of code to use a
+    begin/rollback/commit sequence regardless of whether or not its enclosing
+    code block has begun a transaction.  The :meth:`.flush` method, whether
+    called explicitly or via autoflush, is the primary consumer of the
+    "subtransaction" feature, in that it wishes to guarantee that it works
+    within in a transaction block regardless of whether or not the
+    :class:`.Session` is in transactional mode when the method is called.

+        set of arguments.
+
+        :param autocommit:
+
+          .. warning::
+
+             The autocommit flag is **not for general use**, and if it is
+             used, queries should only be invoked within the span of a
+             :meth:`.Session.begin` / :meth:`.Session.commit` pair.  Executing
+             queries outside of a demarcated transaction is a legacy mode
+             of usage, and can in some cases lead to concurrent connection
+             checkouts.
+
+          Defaults to ``False``. When ``True``, the
+          :class:`.Session` does not keep a persistent transaction running,
+          and will acquire connections from the engine on an as-needed basis,
+          returning them immediately after their use. Flushes will begin and
+          commit (or possibly rollback) their own transaction if no
+          transaction is present. When using this mode, the
+          :meth:`.Session.begin` method is used to explicitly start
+          transactions.
+
+          .. seealso::
+
+            :ref:`session_autocommit`
+
+        :param autoflush: When ``True``, all query operations will issue a
+           :meth:`~.Session.flush` call to this ``Session`` before proceeding.
+           This is a convenience feature so that :meth:`~.Session.flush` need
+           not be called repeatedly in order for database queries to retrieve
+           results. It's typical that ``autoflush`` is used in conjunction with
+           ``autocommit=False``. In this scenario, explicit calls to
+           :meth:`~.Session.flush` are rarely needed; you usually only need to
+           call :meth:`~.Session.commit` (which flushes) to finalize changes.
+
+        :param bind: An optional :class:`.Engine` or :class:`.Connection` to
+           which this ``Session`` should be bound. When specified, all SQL
+           operations performed by this session will execute via this
+           connectable.
+
+        :param binds: An optional dictionary which contains more granular
+           "bind" information than the ``bind`` parameter provides. This
+           dictionary can map individual :class`.Table`
+           instances as well as :class:`~.Mapper` instances to individual
+           :class:`.Engine` or :class:`.Connection` objects. Operations which
+           proceed relative to a particular :class:`.Mapper` will consult this
+           dictionary for the direct :class:`.Mapper` instance as
+           well as the mapper's ``mapped_table`` attribute in order to locate a
+           connectable to use. The full resolution is described in the
+           :meth:`.Session.get_bind`.
+           Usage looks like::
+
+            Session = sessionmaker(binds={
+                SomeMappedClass: create_engine('postgresql://engine1'),
+                somemapper: create_engine('postgresql://engine2'),
+                some_table: create_engine('postgresql://engine3'),
+                })
+
+          Also see the :meth:`.Session.bind_mapper`
+          and :meth:`.Session.bind_table` methods.
+
+        :param \class_: Specify an alternate class other than
+           ``sqlalchemy.orm.session.Session`` which should be used by the
+           returned class. This is the only argument that is local to the
+           :class:`.sessionmaker` function, and is not sent directly to the
+           constructor for ``Session``.
+
+        :param _enable_transaction_accounting:  Defaults to ``True``.  A
+           legacy-only flag which when ``False`` disables *all* 0.5-style
+           object accounting on transaction boundaries, including auto-expiry
+           of instances on rollback and commit, maintenance of the "new" and
+           "deleted" lists upon rollback, and autoflush of pending changes
+           upon :meth:`~.Session.begin`, all of which are interdependent.
+
+        :param expire_on_commit:  Defaults to ``True``. When ``True``, all
+           instances will be fully expired after each :meth:`~.commit`,
+           so that all attribute/object access subsequent to a completed
+           transaction will load from the most recent database state.
+
+        :param extension: An optional
+           :class:`~.SessionExtension` instance, or a list
+           of such instances, which will receive pre- and post- commit and
+           flush events, as well as a post-rollback event. **Deprecated.**
+           Please see :class:`.SessionEvents`.
+
+        :param info: optional dictionary of arbitrary data to be associated
+           with this :class:`.Session`.  Is available via the

+
+        The second positional argument to :meth:`.Session.execute` is an

+        dictionary, or a list of dictionaries, determines whether the DBAPI
+        cursor's ``execute()`` or ``executemany()`` is used to execute the
+        statement.   An INSERT construct may be invoked for a single row::
+
+            result = session.execute(
+                users.insert(), {"id": 7, "name": "somename"})
+
+        or for multiple rows::

+                                ])
+
+        The statement is executed within the current transactional context of
+        this :class:`.Session`.   The :class:`.Connection` which is used
+        to execute the statement can also be acquired directly by
+        calling the :meth:`.Session.connection` method.  Both methods use
+        a rule-based resolution scheme in order to determine the
+        :class:`.Connection`, which in the average case is derived directly
+        from the "bind" of the :class:`.Session` itself, and in other cases
+        can be based on the :func:`.mapper`
+        and :class:`.Table` objects passed to the method; see the
+        documentation for :meth:`.Session.get_bind` for a full description of
+        this scheme.
+
+        The :meth:`.Session.execute` method does *not* invoke autoflush.
+
+        The :class:`.ResultProxy` returned by the :meth:`.Session.execute`
+        method is returned with the "close_with_result" flag set to true;
+        the significance of this flag is that if this :class:`.Session` is
+        autocommitting and does not have a transaction-dedicated
+        :class:`.Connection` available, a temporary :class:`.Connection` is
+        established for the statement execution, which is closed (meaning,
+        returned to the connection pool) when the :class:`.ResultProxy` has
+        consumed all available data. This applies *only* when the
+        :class:`.Session` is configured with autocommit=True and no
+        transaction has been started.

+         any existing related objects or collections that might not
+         be loaded.  The resulting objects from ``load=False`` are always
+         produced as "clean", so it is only appropriate that the given objects

+            use cases and is not recommended for general use.
+
+        Accesses of attributes mapped with :func:`.relationship`
+        will attempt to load a value from the database using this
+        :class:`.Session` as the source of connectivity.  The values
+        will be loaded based on foreign key values present on this
+        object - it follows that this functionality
+        generally only works for many-to-one-relationships.
+
+        The object will be attached to this session, but will
+        **not** participate in any persistence operations; its state
+        for almost all purposes will remain either "transient" or
+        "detached", except for the case of relationship loading.
+
+        Also note that backrefs will often not work as expected.
+        Altering a relationship-bound attribute on the target object
+        may not fire off a backref event, if the effective value
+        is what was already loaded from a foreign-key-holding value.
+
+        The :meth:`.Session.enable_relationship_loading` method is
+        similar to the ``load_on_pending`` flag on :func:`.relationship`.
+        Unlike that flag, :meth:`.Session.enable_relationship_loading` allows
+        an object to remain transient while still being able to load
+        related items.
+
+        To make a transient object associated with a :class:`.Session`
+        via :meth:`.Session.enable_relationship_loading` pending, add
+        it to the :class:`.Session` using :meth:`.Session.add` normally.
+
+        :meth:`.Session.enable_relationship_loading` does not improve
+        behavior when the ORM is used normally - object references should be
+        constructed at the object level, not at the foreign key level, so

+        This method retrieves the history for each instrumented

+        value to its previously committed value, if any.
+
+        It is in effect a more expensive and accurate
+        version of checking for the given instance in the
+        :attr:`.Session.dirty` collection; a full test for
+        each attribute's net "dirty" status is performed.
+
+        E.g.::
+
+            return session.is_modified(someobject)
+
+        .. versionchanged:: 0.8
+            When using SQLAlchemy 0.7 and earlier, the ``passive``
+            flag should **always** be explicitly set to ``True``,
+            else SQL loads/autoflushes may proceed which can affect
+            the modified state itself:
+            ``session.is_modified(someobject, passive=True)``\ .
+            In 0.8 and above, the behavior is corrected and
+            this flag is ignored.
+
+        A few caveats to this method apply:
+
+        * Instances present in the :attr:`.Session.dirty` collection may
+          report ``False`` when tested with this method.  This is because
+          the object may have received change events via attribute mutation,
+          thus placing it in :attr:`.Session.dirty`, but ultimately the state
+          is the same as that loaded from the database, resulting in no net
+          change here.
+        * Scalar attributes may not have recorded the previously set
+          value when a new value was applied, if the attribute was not loaded,
+          or was expired, at the time the new value was received - in these
+          cases, the attribute is assumed to have a change, even if there is
+          ultimately no net change against its database value. SQLAlchemy in
+          most cases does not need the "old" value when a set event occurs, so
+          it skips the expense of a SQL call if the old value isn't present,
+          based on the assumption that an UPDATE of the scalar value is
+          usually needed, and in those few cases where it isn't, is less
+          expensive on average than issuing a defensive SELECT.
+
+          The "old" value is fetched unconditionally upon set only if the
+          attribute container has the ``active_history`` flag set to ``True``.
+          This flag is set typically for primary key attributes and scalar
+          object references that are not a simple many-to-one.  To set this
+          flag for any arbitrary mapped column, use the ``active_history``
+          argument with :func:`.column_property`.
+
+        :param instance: mapped instance to be tested for pending changes.
+        :param include_collections: Indicates if multivalued collections
+         should be included in the operation.  Setting this to ``False`` is a
+         way to detect only local-column based properties (i.e. scalar columns
+         or many-to-one foreign keys) that would result in an UPDATE for this
+         instance upon flush.

+
+        The :class:`.Session` in its default mode of ``autocommit=False``
+        is essentially always in "transaction mode", in that a
+        :class:`.SessionTransaction` is associated with it as soon as
+        it is instantiated.  This :class:`.SessionTransaction` is immediately
+        replaced with a new one as soon as it is ended, due to a rollback,
+        commit, or close operation.
+
+        "Transaction mode" does *not* indicate whether
+        or not actual database connection resources are in use;  the
+        :class:`.SessionTransaction` object coordinates among zero or more
+        actual database transactions, and starts out with none, accumulating
+        individual DBAPI connections as different data sources are used
+        within its scope.   The best way to track when a particular
+        :class:`.Session` has actually begun to use DBAPI resources is to
+        implement a listener using the :meth:`.SessionEvents.after_begin`
+        method, which will deliver both the :class:`.Session` as well as the
+        target :class:`.Connection` to a user-defined event listener.
+
+        The "partial rollback" state refers to when an "inner" transaction,
+        typically used during a flush, encounters an error and emits a
+        rollback of the DBAPI connection.  At this point, the
+        :class:`.Session` is in "partial rollback" and awaits for the user to
+        call :meth:`.Session.rollback`, in order to close out the
+        transaction stack.  It is in this "partial rollback" period that the
+        :attr:`.is_active` flag returns False.  After the call to
+        :meth:`.Session.rollback`, the :class:`.SessionTransaction` is
+        replaced with a new one and :attr:`.is_active` returns ``True`` again.
+
+        When a :class:`.Session` is used in ``autocommit=True`` mode, the
+        :class:`.SessionTransaction` is only instantiated within the scope
+        of a flush call, or when :meth:`.Session.begin` is called.  So
+        :attr:`.is_active` will always be ``False`` outside of a flush or
+        :meth:`.Session.begin` block in this mode, and will be ``True``
+        within the :meth:`.Session.begin` block as long as it doesn't enter
+        "partial rollback" state.
+
+        From all the above, it follows that the only purpose to this flag is
+        for application frameworks that wish to detect is a "rollback" is
+        necessary within a generic error handling routine, for
+        :class:`.Session` objects that would otherwise be in
+        "partial rollback" mode.  In a typical integration case, this is also
+        not necessary as it is standard practice to emit
+        :meth:`.Session.rollback` unconditionally within the outermost
+        exception catch.
+
+        To track the transactional state of a :class:`.Session` fully,
+        use event listeners, primarily the :meth:`.SessionEvents.after_begin`,
+        :meth:`.SessionEvents.after_commit`,
+        :meth:`.SessionEvents.after_rollback` and related events.

+class Load(Generative, MapperOption):
+    """Represents loader options which modify the state of a
+    :class:`.Query` in order to affect how various mapped attributes are
+    loaded.
+
+    .. versionadded:: 0.9.0 The :meth:`.Load` system is a new foundation for
+       the existing system of loader options, including options such as
+       :func:`.orm.joinedload`, :func:`.orm.defer`, and others.   In
+       particular, it introduces a new method-chained system that replaces the
+       need for dot-separated paths as well as "_all()" options such as
+       :func:`.orm.joinedload_all`.
+
+    A :class:`.Load` object can be used directly or indirectly.  To use one
+    directly, instantiate given the parent class.  This style of usage is
+    useful when dealing with a :class:`.Query` that has multiple entities,
+    or when producing a loader option that can be applied generically to
+    any style of query::
+
+        myopt = Load(MyClass).joinedload("widgets")
+
+    The above ``myopt`` can now be used with :meth:`.Query.options`::
+
+        session.query(MyClass).options(myopt)
+
+    The :class:`.Load` construct is invoked indirectly whenever one makes use
+    of the various loader options that are present in ``sqlalchemy.orm``,
+    including options such as :func:`.orm.joinedload`, :func:`.orm.defer`,
+    :func:`.orm.subqueryload`, and all the rest.  These constructs produce an
+    "anonymous" form of the :class:`.Load` object which tracks attributes and
+    options, but is not linked to a parent class until it is associated with a
+    parent :class:`.Query`::
+
+        # produce "unbound" Load object
+        myopt = joinedload("widgets")
+
+        # when applied using options(), the option is "bound" to the
+        # class observed in the given query, e.g. MyClass
+        session.query(MyClass).options(myopt)
+
+    Whether the direct or indirect style is used, the :class:`.Load` object
+    returned now represents a specific "path" along the entities of a
+    :class:`.Query`.  This path can be traversed using a standard
+    method-chaining approach.  Supposing a class hierarchy such as ``User``,
+    ``User.addresses -> Address``, ``User.orders -> Order`` and
+    ``Order.items -> Item``, we can specify a variety of loader options along
+    each element in the "path"::
+
+        session.query(User).options(
+                    joinedload("addresses"),
+                    subqueryload("orders").joinedload("items")
+                )
+
+    Where above, the ``addresses`` collection will be joined-loaded, the
+    ``orders`` collection will be subquery-loaded, and within that subquery
+    load the ``items`` collection will be joined-loaded.

+    This function has several call styles:
+
+    * ``identity_key(class, ident)``
+
+      This form receives a mapped class and a primary key scalar or
+      tuple as an argument.
+
+      E.g.::
+
+        >>> identity_key(MyClass, (1, 2))
+        (<class '__main__.MyClass'>, (1, 2))
+
+      :param class: mapped class (must be a positional argument)
+      :param ident: primary key, may be a scalar or tuple argument.
+
+
+    * ``identity_key(instance=instance)``
+
+      This form will produce the identity key for a given instance.  The
+      instance need not be persistent, only that its primary key attributes
+      are populated (else the key will contain ``None`` for those missing
+      values).
+
+      E.g.::
+
+        >>> instance = MyClass(1, 2)
+        >>> identity_key(instance=instance)
+        (<class '__main__.MyClass'>, (1, 2))
+
+      In this form, the given instance is ultimately run though
+      :meth:`.Mapper.identity_key_from_instance`, which will have the
+      effect of performing a database check for the corresponding row
+      if the object is expired.
+
+      :param instance: object instance (must be given as a keyword arg)
+
+    * ``identity_key(class, row=row)``
+
+      This form is similar to the class/tuple form, except is passed a
+      database result row as a :class:`.RowProxy` object.
+
+      E.g.::
+
+        >>> row = engine.execute("select * from table where a=1 and b=2").\
+first()
+        >>> identity_key(MyClass, row=row)
+        (<class '__main__.MyClass'>, (1, 2))
+
+      :param class: mapped class (must be a positional argument)
+      :param row: :class:`.RowProxy` row returned by a :class:`.ResultProxy`
+       (must be given as a keyword arg)

+
+    For convenience, the :func:`.aliased` function also accepts plain

+        objects don't include an enclosing SELECT.  This can lead to more
+        efficient queries in many circumstances.  A JOIN against a nested JOIN
+        will be rewritten as a JOIN against an aliased SELECT subquery on
+        backends that don't support this syntax.
+
+     Setting ``flat`` to ``True`` implies the ``aliased`` flag is

+        among tables automatically. If used, the ``selectable`` argument

+                            for const in column.constraints)
+            return text
+
+    The above construct can be applied to a :class:`.Table` as follows::
+
+        from sqlalchemy import Table, Metadata, Column, Integer, String
+        from sqlalchemy import schema
+
+        metadata = MetaData()
+
+        table = Table('mytable', MetaData(),
+                Column('x', Integer, info={"special":True}, primary_key=True),
+                Column('y', String(50)),
+                Column('z', String(20), info={"special":True})
+            )
+
+        metadata.create_all(conn)
+
+    Above, the directives we've added to the :attr:`.Column.info` collection
+    will be detected by our custom compilation scheme::
+
+        CREATE TABLE mytable (
+                x SPECIAL DIRECTIVE INTEGER NOT NULL,
+                y VARCHAR(50),
+                z SPECIAL DIRECTIVE VARCHAR(20),
+            PRIMARY KEY (x)
+        )
+
+    The :class:`.CreateColumn` construct can also be used to skip certain
+    columns when producing a ``CREATE TABLE``.  This is accomplished by
+    creating a compilation rule that conditionally returns ``None``.
+    This is essentially how to produce the same effect as using the
+    ``system=True`` argument on :class:`.Column`, which marks a column
+    as an implicitly-present "system" column.
+
+    For example, suppose we wish to produce a :class:`.Table` which skips
+    rendering of the Postgresql ``xmin`` column against the Postgresql
+    backend, but on other backends does render it, in anticipation of a
+    triggered rule.  A conditional compilation rule could skip this name only
+    on Postgresql::
+
+        from sqlalchemy.schema import CreateColumn
+
+        @compiles(CreateColumn, "postgresql")
+        def skip_xmin(element, compiler, **kw):
+            if element.element.name == 'xmin':
+                return None
+            else:
+                return compiler.visit_create_column(element, **kw)
+
+
+        my_table = Table('mytable', metadata,
+                    Column('id', Integer, primary_key=True),
+                    Column('xmin', Integer)
+                )
+
+    Above, a :class:`.CreateTable` construct will generate a ``CREATE TABLE``
+    which only includes the ``id`` column in the string; the ``xmin`` column
+    will be omitted, but only against the Postgresql backend.
+
+    .. versionadded:: 0.8.3 The :class:`.CreateColumn` construct supports
+       skipping of columns by returning ``None`` from a custom compilation
+       rule.

+
+        Multiple calls to :meth:`.ValuesBase.values` will produce a new

+         either through multiple :meth:`.ValuesBase.values` calls
+         or by sending a list + kwargs at the same time.
+
+         .. note::
+
+             Passing a multiple values list is *not* the same
+             as passing a multiple values list to the
+             :meth:`.Connection.execute` method.  Passing a list of parameter
+             sets to :meth:`.ValuesBase.values` produces a construct of this

+
+             whereas a multiple list passed to :meth:`.Connection.execute`
+             has the effect of using the DBAPI
+             `executemany() <http://www.python.org/dev/peps/pep-0249/#id18>`_
+             method, which provides a high-performance system of invoking

+             of parameter sets.   The "executemany" style is supported by

+           intact with a collection of any number of rows.
+
+        2. It is compatible with the existing logic to fetch auto-generated
+           primary key values, also known as "implicit returning".  Backends
+           that support RETURNING will automatically make use of RETURNING in
+           order to fetch the value of newly generated primary keys; while the
+           :meth:`.UpdateBase.returning` method circumvents this behavior,
+           :meth:`.ValuesBase.return_defaults` leaves it intact.
+
+        3. It can be called against any backend.  Backends that don't support
+           RETURNING will skip the usage of the feature, rather than raising
+           an exception.  The return value of
+           :attr:`.ResultProxy.returned_defaults` will be ``None``
+

+          statement.   When compiled standalone without any parameters,
+          the ``SET`` clause generates for all columns.
+

+          UPDATE statement.

+          be available in the dictionary returned from
+          :meth:`.ResultProxy.last_updated_params`.
+
+        If both ``values`` and compile-time bind parameters are present, the
+        compile-time bind parameters override the information specified
+        within ``values`` on a per-key basis.
+
+        The keys within ``values`` can be either :class:`.Column`
+        objects or their string identifiers (specifically the "key" of the
+        :class:`.Column`, normally but not necessarily equivalent to
+        its "name").  Normally, the
+        :class:`.Column` objects used here are expected to be
+        part of the target :class:`.Table` that is the table
+        to be updated.  However when using MySQL, a multiple-table
+        UPDATE statement can refer to columns from any of
+        the tables referred to in the WHERE clause.
+
+        The values referred to in ``values`` are typically:
+
+        * a literal data value (i.e. string, number, etc.)
+        * a SQL expression, such as a related :class:`.Column`,

+
+        When combining :func:`.select` constructs within the values

+        the subquery represented by the :func:`.select` should be

+
+    While the most familiar kind of :class:`.ColumnElement` is the
+    :class:`.Column` object, :class:`.ColumnElement` serves as the basis
+    for any unit that may be present in a SQL expression, including
+    the expressions themselves, SQL functions, bound parameters,
+    literal expressions, keywords such as ``NULL``, etc.
+    :class:`.ColumnElement` is the ultimate base class for all such elements.
+
+    A wide variety of SQLAlchemy Core functions work at the SQL expression
+    level, and are intended to accept instances of :class:`.ColumnElement` as
+    arguments.  These functions will typically document that they accept a
+    "SQL expression" as an argument.  What this means in terms of SQLAlchemy
+    usually refers to an input which is either already in the form of a
+    :class:`.ColumnElement` object, or a value which can be **coerced** into
+    one.  The coercion rules followed by most, but not all, SQLAlchemy Core
+    functions with regards to SQL expressions are as follows:
+
+        * a literal Python value, such as a string, integer or floating
+          point value, boolean, datetime, ``Decimal`` object, or virtually
+          any other Python object, will be coerced into a "literal bound
+          value".  This generally means that a :func:`.bindparam` will be
+          produced featuring the given value embedded into the construct; the
+          resulting :class:`.BindParameter` object is an instance of
+          :class:`.ColumnElement`.  The Python value will ultimately be sent
+          to the DBAPI at execution time as a paramterized argument to the
+          ``execute()`` or ``executemany()`` methods, after SQLAlchemy
+          type-specific converters (e.g. those provided by any associated
+          :class:`.TypeEngine` objects) are applied to the value.
+
+        * any special object value, typically ORM-level constructs, which
+          feature a method called ``__clause_element__()``.  The Core
+          expression system looks for this method when an object of otherwise
+          unknown type is passed to a function that is looking to coerce the
+          argument into a :class:`.ColumnElement` expression.  The
+          ``__clause_element__()`` method, if present, should return a
+          :class:`.ColumnElement` instance.  The primary use of
+          ``__clause_element__()`` within SQLAlchemy is that of class-bound
+          attributes on ORM-mapped classes; a ``User`` class which contains a
+          mapped attribute named ``.name`` will have a method
+          ``User.name.__clause_element__()`` which when invoked returns the
+          :class:`.Column` called ``name`` associated with the mapped table.
+
+        * The Python ``None`` value is typically interpreted as ``NULL``,
+          which in SQLAlchemy Core produces an instance of :func:`.null`.
+
+    A :class:`.ColumnElement` provides the ability to generate new
+    :class:`.ColumnElement`
+    objects using Python expressions.  This means that Python operators
+    such as ``==``, ``!=`` and ``<`` are overloaded to mimic SQL operations,
+    and allow the instantiation of further :class:`.ColumnElement` instances
+    which are composed from other, more fundamental :class:`.ColumnElement`
+    objects.  For example, two :class:`.ColumnClause` objects can be added
+    together with the addition operator ``+`` to produce
+    a :class:`.BinaryExpression`.
+    Both :class:`.ColumnClause` and :class:`.BinaryExpression` are subclasses
+    of :class:`.ColumnElement`::
+
+        >>> from sqlalchemy.sql import column
+        >>> column('a') + column('b')
+        <sqlalchemy.sql.expression.BinaryExpression object at 0x101029dd0>
+        >>> print column('a') + column('b')
+        a + b

+        "placeholder" value in a SQL expression, the value of which is
+        supplied at the point at which the statement in executed against a
+        database connection.
+
+        In SQLAlchemy, the :func:`.bindparam` construct has
+        the ability to carry along the actual value that will be ultimately
+        used at expression time.  In this way, it serves not just as
+        a "placeholder" for eventual population, but also as a means of
+        representing so-called "unsafe" values which should not be rendered
+        directly in a SQL statement, but rather should be passed along
+        to the :term:`DBAPI` as values which need to be correctly escaped
+        and potentially handled for type-safety.
+
+        When using :func:`.bindparam` explicitly, the use case is typically
+        one of traditional deferment of parameters; the :func:`.bindparam`
+        construct accepts a name which can then be referred to at execution
+        time::
+
+            from sqlalchemy import bindparam
+
+            stmt = select([users_table]).\\
+                        where(users_table.c.name == bindparam('username'))
+
+        The above statement, when rendered, will produce SQL similar to::
+
+            SELECT id, name FROM user WHERE name = :username
+
+        In order to populate the value of ``:username`` above, the value
+        would typically be applied at execution time to a method
+        like :meth:`.Connection.execute`::
+
+            result = connection.execute(stmt, username='wendy')
+
+        Explicit use of :func:`.bindparam` is also common when producing
+        UPDATE or DELETE statements that are to be invoked multiple times,
+        where the WHERE criterion of the statement is to change on each
+        invocation, such as::
+
+            stmt = (users_table.update().
+                    where(user_table.c.name == bindparam('username')).
+                    values(fullname=bindparam('fullname'))
+                    )
+
+            connection.execute(
+                stmt, [{"username": "wendy", "fullname": "Wendy Smith"},
+                       {"username": "jack", "fullname": "Jack Jones"},
+                       ]
+            )
+
+        SQLAlchemy's Core expression system makes wide use of
+        :func:`.bindparam` in an implicit sense.   It is typical that Python
+        literal values passed to virtually all SQL expression functions are
+        coerced into fixed :func:`.bindparam` constructs.  For example, given
+        a comparison operation such as::
+
+            expr = users_table.c.name == 'Wendy'
+
+        The above expression will produce a :class:`.BinaryExpression`
+        construct, where the left side is the :class:`.Column` object
+        representing the ``name`` column, and the right side is a
+        :class:`.BindParameter` representing the literal value::
+
+            print(repr(expr.right))
+            BindParameter('%(4327771088 name)s', 'Wendy', type_=String())
+
+        The expression above will render SQL such as::
+
+            user.name = :name_1
+
+        Where the ``:name_1`` parameter name is an anonymous name.  The
+        actual string ``Wendy`` is not in the rendered string, but is carried
+        along where it is later used within statement execution.  If we
+        invoke a statement like the following::
+
+            stmt = select([users_table]).where(users_table.c.name == 'Wendy')
+            result = connection.execute(stmt)
+
+        We would see SQL logging output as::
+
+            SELECT "user".id, "user".name
+            FROM "user"
+            WHERE "user".name = %(name_1)s
+            {'name_1': 'Wendy'}
+
+        Above, we see that ``Wendy`` is passed as a parameter to the database,
+        while the placeholder ``:name_1`` is rendered in the appropriate form
+        for the target database, in this case the Postgresql database.
+
+        Similarly, :func:`.bindparam` is invoked automatically
+        when working with :term:`CRUD` statements as far as the "VALUES"
+        portion is concerned.   The :func:`.insert` construct produces an
+        ``INSERT`` expression which will, at statement execution time,
+        generate bound placeholders based on the arguments passed, as in::
+
+            stmt = users_table.insert()
+            result = connection.execute(stmt, name='Wendy')
+
+        The above will produce SQL output as::
+
+            INSERT INTO "user" (name) VALUES (%(name)s)
+            {'name': 'Wendy'}
+
+        The :class:`.Insert` construct, at compilation/execution time,
+        rendered a single :func:`.bindparam` mirroring the column
+        name ``name`` as a result of the single ``name`` parameter
+        we passed to the :meth:`.Connection.execute` method.
+
+        :param key:
+          the key (e.g. the name) for this bind param.
+          Will be used in the generated
+          SQL statement for dialects that use named parameters.  This
+          value may be modified when part of a compilation operation,
+          if other :class:`BindParameter` objects exist with the same
+          key, or if its length is too long and truncation is
+          required.
+
+        :param value:
+          Initial value for this bind param.  Will be used at statement
+          execution time as the value for this parameter passed to the
+          DBAPI, if no other value is indicated to the statement execution
+          method for this particular parameter name.  Defaults to ``None``.
+
+        :param callable\_:
+          A callable function that takes the place of "value".  The function
+          will be called at statement execution time to determine the
+          ultimate value.   Used for scenarios where the actual bind
+          value cannot be determined at the point at which the clause
+          construct is created, but embedded bind values are still desirable.
+
+        :param type\_:
+          A :class:`.TypeEngine` class or instance representing an optional
+          datatype for this :func:`.bindparam`.  If not passed, a type
+          may be determined automatically for the bind, based on the given
+          value; for example, trivial Python types such as ``str``,
+          ``int``, ``bool``
+          may result in the :class:`.String`, :class:`.Integer` or
+          :class:`.Boolean` types being autoamtically selected.
+
+          The type of a :func:`.bindparam` is significant especially in that
+          the type will apply pre-processing to the value before it is
+          passed to the database.  For example, a :func:`.bindparam` which
+          refers to a datetime value, and is specified as holding the
+          :class:`.DateTime` type, may apply conversion needed to the
+          value (such as stringification on SQLite) before passing the value
+          to the database.
+
+        :param unique:
+          if True, the key name of this :class:`.BindParameter` will be
+          modified if another :class:`.BindParameter` of the same name
+          already has been located within the containing
+          expression.  This flag is used generally by the internals
+          when producing so-called "anonymous" bound expressions, it
+          isn't generally applicable to explicitly-named :func:`.bindparam`
+          constructs.
+
+        :param required:
+          If ``True``, a value is required at execution time.  If not passed,
+          it defaults to ``True`` if neither :paramref:`.bindparam.value`
+          or :paramref:`.bindparam.callable` were passed.  If either of these
+          parameters are present, then :paramref:`.bindparam.required`
+          defaults to ``False``.
+
+          .. versionchanged:: 0.8 If the ``required`` flag is not specified,
+             it will be set automatically to ``True`` or ``False`` depending
+             on whether or not the ``value`` or ``callable`` parameters
+             were specified.
+
+        :param quote:
+          True if this parameter name requires quoting and is not
+          currently known as a SQLAlchemy reserved word; this currently
+          only applies to the Oracle backend, where bound names must
+          sometimes be quoted.
+
+        :param isoutparam:
+          if True, the parameter should be treated like a stored procedure

+
+            t = text("SELECT * FROM users")
+            result = connection.execute(t)
+
+        The advantages :func:`.text` provides over a plain string are
+        backend-neutral support for bind parameters, per-statement
+        execution options, as well as
+        bind parameter and result-column typing behavior, allowing
+        SQLAlchemy type constructs to play a role when executing
+        a statement that is specified literally.  The construct can also
+        be provided with a ``.c`` collection of column elements, allowing
+        it to be embedded in other SQL expression constructs as a subquery.
+
+        Bind parameters are specified by name, using the format ``:name``.
+        E.g.::
+
+            t = text("SELECT * FROM users WHERE id=:user_id")
+            result = connection.execute(t, user_id=12)
+
+        For SQL statements where a colon is required verbatim, as within
+        an inline string, use a backslash to escape::
+
+            t = text("SELECT * FROM users WHERE name='\\:username'")
+
+        The :class:`.TextClause` construct includes methods which can
+        provide information about the bound parameters as well as the column
+        values which would be returned from the textual statement, assuming
+        it's an executable SELECT type of statement.  The
+        :meth:`.TextClause.bindparams` method is used to provide bound
+        parameter detail, and :meth:`.TextClause.columns` method allows
+        specification of return columns including names and types::
+
+            t = text("SELECT * FROM users WHERE id=:user_id").\\
+                    bindparams(user_id=7).\\
+                    columns(id=Integer, name=String)
+
+            for id, name in connection.execute(t):
+                print(id, name)
+
+        The :func:`.text` construct is used internally in cases when
+        a literal string is specified for part of a larger query, such as
+        when a string is specified to the :meth:`.Select.where` method of
+        :class:`.Select`.  In those cases, the same
+        bind parameter syntax is applied::
+
+            s = select([users.c.id, users.c.name]).where("id=:user_id")
+            result = connection.execute(s, user_id=12)
+
+        Using :func:`.text` explicitly usually implies the construction
+        of a full, standalone statement.   As such, SQLAlchemy refers
+        to it as an :class:`.Executable` object, and it supports
+        the :meth:`Executable.execution_options` method.  For example,
+        a :func:`.text` construct that should be subject to "autocommit"
+        can be set explicitly so using the
+        :paramref:`.Connection.execution_options.autocommit` option::
+
+            t = text("EXEC my_procedural_thing()").\\
+                    execution_options(autocommit=True)
+
+        Note that SQLAlchemy's usual "autocommit" behavior applies to
+        :func:`.text` constructs implicitly - that is, statements which begin
+        with a phrase such as ``INSERT``, ``UPDATE``, ``DELETE``,
+        or a variety of other phrases specific to certain backends, will
+        be eligible for autocommit if no transaction is in progress.
+
+        :param text:
+          the text of the SQL statement to be created.  use ``:<param>``
+          to specify bind parameters; they will be compiled to their
+          engine-specific format.
+
+        :param autocommit:
+          Deprecated.  Use .execution_options(autocommit=<True|False>)
+          to set the autocommit option.
+
+        :param bind:
+          an optional connection or engine to be used for this text query.

+        :param bindparams:
+          Deprecated.  A list of :func:`.bindparam` instances used to
+          provide information about parameters embedded in the statement.
+          This argument now invokes the :meth:`.TextClause.bindparams`
+          method on the construct before returning it.  E.g.::
+
+              stmt = text("SELECT * FROM table WHERE id=:id",
+                        bindparams=[bindparam('id', value=5, type_=Integer)])

+          .. deprecated:: 0.9.0 the :meth:`.TextClause.bindparams` method

+          to type objects,

+          :class:`.TextAsFrom` construct that gains a ``.c`` collection and
+          can be embedded in other expressions.  E.g.::
+
+              stmt = text("SELECT * FROM table",
+                            typemap={'id': Integer, 'name': String},

+        bind.  In the case of ``name`` we also set the default value of

+
+    :class:`.quoted_name` is a Python unicode/str subclass which
+    represents a particular identifier name along with a
+    ``quote`` flag.  This ``quote`` flag, when set to
+    ``True`` or ``False``, overrides automatic quoting behavior
+    for this identifier in order to either unconditionally quote
+    or to not quote the name.  If left at its default of ``None``,
+    quoting behavior is applied to the identifier on a per-backend basis
+    based on an examination of the token itself.
+
+    A :class:`.quoted_name` object with ``quote=True`` is also
+    prevented from being modified in the case of a so-called
+    "name normalize" option.  Certain database backends, such as
+    Oracle, Firebird, and DB2 "normalize" case-insensitive names
+    as uppercase.  The SQLAlchemy dialects for these backends
+    convert from SQLAlchemy's lower-case-means-insensitive convention
+    to the upper-case-means-insensitive conventions of those backends.
+    The ``quote=True`` flag here will prevent this conversion from occurring
+    to support an identifier that's quoted as all lower case against
+    such a backend.
+
+    The :class:`.quoted_name` object is normally created automatically
+    when specifying the name for key schema constructs such as
+    :class:`.Table`, :class:`.Column`, and others.  The class can also be
+    passed explicitly as the name to any function that receives a name which
+    can be quoted.  Such as to use the :meth:`.Engine.has_table` method with
+    an unconditionally quoted name::
+
+        from sqlaclchemy import create_engine
+        from sqlalchemy.sql.elements import quoted_name
+
+        engine = create_engine("oracle+cx_oracle://some_dsn")
+        engine.has_table(quoted_name("some_table", True))
+
+    The above logic will run the "has table" logic against the Oracle backend,
+    passing the name exactly as ``"some_table"`` without converting to
+    upper case.

+

+    The name of the above constraint will be rendered as ``"ck_t_x5"``.
+    That is, the existing name ``x5`` is used in the naming convention as the
+    ``constraint_name`` token.
+
+    In some situations, such as in migration scripts, we may be rendering
+    the above :class:`.CheckConstraint` with a name that's already been
+    converted.  In order to make sure the name isn't double-modified, the
+    new name is applied using the :func:`.schema.conv` marker.  We can

+
+
+        m = MetaData(naming_convention={

+                        CheckConstraint('x > 5', name=conv('ck_t_x5')))
+
+    Where above, the :func:`.schema.conv` marker indicates that the constraint
+    name here is final, and the name will render as ``"ck_t_x5"`` and not
+    ``"ck_t_ck_t_x5"``

+        count(:param_1)
+

+   used in that way::
+
+        >>> print select([func.count(table.c.id)])
+        SELECT count(sometable.id) FROM sometable
+
+   Any name can be given to :data:`.func`. If the function name is unknown to
+   SQLAlchemy, it will be rendered exactly as is. For common SQL functions
+   which SQLAlchemy is aware of, the name may be interpreted as a *generic
+   function* which will be compiled appropriately to the target database::
+
+        >>> print func.current_timestamp()
+        CURRENT_TIMESTAMP
+
+   To call functions which are present in dot-separated packages,

+
+        >>> print func.stats.yield_curve(5, 10)
+        stats.yield_curve(:yield_curve_1, :yield_curve_2)
+
+   SQLAlchemy can be made aware of the return type of functions to enable
+   type-specific lexical and result-based behavior. For example, to ensure
+   that a string-based function returns a Unicode value and is similarly
+   treated as a string in expressions, specify
+   :class:`~sqlalchemy.types.Unicode` as the type:
+
+        >>> print func.my_string(u'hi', type_=Unicode) + ' ' + \
+        ... func.my_string(u'there', type_=Unicode)
+        my_string(:my_string_1) || :my_string_2 || my_string(:my_string_3)
+
+   The object returned by a :data:`.func` call is usually an instance of
+   :class:`.Function`.
+   This object meets the "column" interface, including comparison and labeling
+   functions.  The object can also be passed the :meth:`~.Connectable.execute`
+   method of a :class:`.Connection` or :class:`.Engine`, where it will be
+   wrapped inside of a SELECT statement first::
+
+        print connection.execute(func.current_timestamp()).scalar()
+
+   In a few exception cases, the :data:`.func` accessor
+   will redirect a name to a built-in expression such as :func:`.cast`
+   or :func:`.extract`, as these names have well-known meaning
+   but are not exactly the same as "functions" from a SQLAlchemy
+   perspective.
+
+   .. versionadded:: 0.8 :data:`.func` can return non-function expression
+      constructs for common quasi-functional names like :func:`.cast`
+      and :func:`.extract`.

+   calculate their return type automatically. For a listing of known generic
+   functions, see :ref:`generic_functions`.

+        The :data:`.func` construct has only limited support for calling

+
+    A generic function is a pre-established :class:`.Function`
+    class that is instantiated automatically when called
+    by name from the :data:`.func` attribute.    Note that
+    calling any name from :data:`.func` has the effect that
+    a new :class:`.Function` instance is created automatically,
+    given that name.  The primary use case for defining
+    a :class:`.GenericFunction` class is so that a function
+    of a particular name may be given a fixed return type.
+    It can also include custom argument parsing schemes as well
+    as additional methods.
+
+    Subclasses of :class:`.GenericFunction` are automatically
+    registered under the name of the class.  For
+    example, a user-defined function ``as_utc()`` would
+    be available immediately::
+
+        from sqlalchemy.sql.functions import GenericFunction
+        from sqlalchemy.types import DateTime
+
+        class as_utc(GenericFunction):
+            type = DateTime
+
+        print select([func.as_utc()])
+
+    User-defined generic functions can be organized into
+    packages by specifying the "package" attribute when defining
+    :class:`.GenericFunction`.   Third party libraries
+    containing many functions may want to use this in order
+    to avoid name conflicts with other systems.   For example,
+    if our ``as_utc()`` function were part of a package
+    "time"::
+
+        class as_utc(GenericFunction):
+            type = DateTime
+            package = "time"
+
+    The above function would be available from :data:`.func`
+    using the package name ``time``::
+
+        print select([func.time.as_utc()])
+
+    A final option is to allow the function to be accessed
+    from one name in :data:`.func` but to render as a different name.
+    The ``identifier`` attribute will override the name used to
+    access the function as loaded from :data:`.func`, but will retain
+    the usage of ``name`` as the rendered name::
+
+        class GeoBuffer(GenericFunction):
+            type = Geometry
+            package = "geo"
+            name = "ST_Buffer"
+            identifier = "buffer"
+
+    The above function will render as follows::
+
+        >>> print func.geo.buffer()
+        ST_Buffer()
+
+    .. versionadded:: 0.8 :class:`.GenericFunction` now supports
+       automatic registration of new functions as well as package
+       and custom naming support.
+
+    .. versionchanged:: 0.8 The attribute name ``type`` is used
+       to specify the function's return type at the class level.
+       Previously, the name ``__return_type__`` was used.  This

+"""The schema module provides the building blocks for database metadata.
+
+Each element within this module describes a database entity which can be
+created and dropped, or is otherwise part of such an entity.  Examples include
+tables, columns, sequences, and indexes.
+
+All entities are subclasses of :class:`~sqlalchemy.schema.SchemaItem`, and as
+defined in this module they are intended to be agnostic of any vendor-specific
+constructs.
+
+A collection of entities are grouped into a unit called
+:class:`~sqlalchemy.schema.MetaData`. MetaData serves as a logical grouping of
+schema elements, and can also be associated with an actual database connection
+such that operations involving the contained elements can contact the database
+as needed.
+
+Two of the elements here also build upon their "syntactic" counterparts, which
+are defined in :class:`~sqlalchemy.sql.expression.`, specifically
+:class:`~sqlalchemy.schema.Table` and :class:`~sqlalchemy.schema.Column`.
+Since these objects are part of the SQL expression language, they are usable
+as components in SQL expressions.

+    :class:`.MetaData` object. Calling the :class:`.Table`
+    constructor with the same name and same :class:`.MetaData` argument
+    a second time will return the *same* :class:`.Table` object - in this way
+    the :class:`.Table` constructor acts as a registry function.
+
+    .. seealso::
+
+        :ref:`metadata_describing` - Introduction to database metadata
+
+    Constructor arguments are as follows:
+
+    :param name: The name of this table as represented in the database.
+
+        The table name, along with the value of the ``schema`` parameter,
+        forms a key which uniquely identifies this :class:`.Table` within
+        the owning :class:`.MetaData` collection.
+        Additional calls to :class:`.Table` with the same name, metadata,
+        and schema name will return the same :class:`.Table` object.
+
+        Names which contain no upper case characters
+        will be treated as case insensitive names, and will not be quoted
+        unless they are a reserved word or contain special characters.
+        A name with any number of upper case characters is considered
+        to be case sensitive, and will be sent as quoted.
+
+        To enable unconditional quoting for the table name, specify the flag
+        ``quote=True`` to the constructor, or use the :class:`.quoted_name`
+        construct to specify the name.
+
+    :param metadata: a :class:`.MetaData` object which will contain this
+        table.  The metadata is used as a point of association of this table
+        with other tables which are referenced via foreign key.  It also
+        may be used to associate this table with a particular
+        :class:`.Connectable`.
+
+    :param \*args: Additional positional arguments are used primarily
+        to add the list of :class:`.Column` objects contained within this
+        table. Similar to the style of a CREATE TABLE statement, other
+        :class:`.SchemaItem` constructs may be added here, including
+        :class:`.PrimaryKeyConstraint`, and :class:`.ForeignKeyConstraint`.
+
+    :param autoload: Defaults to False: the Columns for this table should
+        be reflected from the database. Usually there will be no Column
+        objects in the constructor if this property is set.
+
+    :param autoload_replace: If ``True``, when using ``autoload=True``
+        and ``extend_existing=True``,
+        replace ``Column`` objects already present in the ``Table`` that's
+        in the ``MetaData`` registry with
+        what's reflected.  Otherwise, all existing columns will be
+        excluded from the reflection process.    Note that this does
+        not impact ``Column`` objects specified in the same call to ``Table``
+        which includes ``autoload``, those always take precedence.
+        Defaults to ``True``.
+
+        .. versionadded:: 0.7.5
+
+    :param autoload_with: If autoload==True, this is an optional Engine
+        or Connection instance to be used for the table reflection. If
+        ``None``, the underlying MetaData's bound connectable will be used.
+
+    :param extend_existing: When ``True``, indicates that if this
+        :class:`.Table` is already present in the given :class:`.MetaData`,
+        apply further arguments within the constructor to the existing
+        :class:`.Table`.
+
+        If ``extend_existing`` or ``keep_existing`` are not set, an error is
+        raised if additional table modifiers are specified when
+        the given :class:`.Table` is already present in the
+        :class:`.MetaData`.
+
+        .. versionchanged:: 0.7.4
+            ``extend_existing`` will work in conjunction
+            with ``autoload=True`` to run a new reflection operation against
+            the database; new :class:`.Column` objects will be produced
+            from database metadata to replace those existing with the same
+            name, and additional :class:`.Column` objects not present
+            in the :class:`.Table` will be added.
+
+        As is always the case with ``autoload=True``, :class:`.Column`
+        objects can be specified in the same :class:`.Table` constructor,
+        which will take precedence.  I.e.::
+
+            Table("mytable", metadata,
+                        Column('y', Integer),
+                        extend_existing=True,
+                        autoload=True,
+                        autoload_with=engine
+                    )
+
+        The above will overwrite all columns within ``mytable`` which
+        are present in the database, except for ``y`` which will be used as is
+        from the above definition.   If the ``autoload_replace`` flag
+        is set to False, no existing columns will be replaced.
+
+    :param implicit_returning: True by default - indicates that
+        RETURNING can be used by default to fetch newly inserted primary key
+        values, for backends which support this.  Note that
+        create_engine() also provides an implicit_returning flag.
+
+    :param include_columns: A list of strings indicating a subset of
+        columns to be loaded via the ``autoload`` operation; table columns who
+        aren't present in this list will not be represented on the resulting
+        ``Table`` object. Defaults to ``None`` which indicates all columns
+        should be reflected.
+
+    :param info: Optional data dictionary which will be populated into the
+        :attr:`.SchemaItem.info` attribute of this object.
+
+    :param keep_existing: When ``True``, indicates that if this Table
+        is already present in the given :class:`.MetaData`, ignore
+        further arguments within the constructor to the existing
+        :class:`.Table`, and return the :class:`.Table` object as
+        originally created. This is to allow a function that wishes
+        to define a new :class:`.Table` on first call, but on
+        subsequent calls will return the same :class:`.Table`,
+        without any of the declarations (particularly constraints)
+        being applied a second time. Also see extend_existing.
+
+        If extend_existing or keep_existing are not set, an error is
+        raised if additional table modifiers are specified when
+        the given :class:`.Table` is already present in the
+        :class:`.MetaData`.
+
+    :param listeners: A list of tuples of the form ``(<eventname>, <fn>)``
+        which will be passed to :func:`.event.listen` upon construction.
+        This alternate hook to :func:`.event.listen` allows the establishment
+        of a listener function specific to this :class:`.Table` before
+        the "autoload" process begins.  Particularly useful for
+        the :meth:`.DDLEvents.column_reflect` event::
+
+            def listen_for_reflect(table, column_info):
+                "handle the column reflection event"
+                # ...
+
+            t = Table(
+                'sometable',
+                autoload=True,
+                listeners=[
+                    ('column_reflect', listen_for_reflect)
+                ])
+
+    :param mustexist: When ``True``, indicates that this Table must already
+        be present in the given :class:`.MetaData` collection, else
+        an exception is raised.
+
+    :param prefixes:
+        A list of strings to insert after CREATE in the CREATE TABLE
+        statement.  They will be separated by spaces.
+
+    :param quote: Force quoting of this table's name on or off, corresponding
+        to ``True`` or ``False``.  When left at its default of ``None``,
+        the column identifier will be quoted according to whether the name is
+        case sensitive (identifiers with at least one upper case character are
+        treated as case sensitive), or if it's a reserved word.  This flag
+        is only needed to force quoting of a reserved word which is not known
+        by the SQLAlchemy dialect.
+
+    :param quote_schema: same as 'quote' but applies to the schema identifier.
+
+    :param schema: The schema name for this table, which is required if
+        the table resides in a schema other than the default selected schema
+        for the engine's database connection.  Defaults to ``None``.
+
+        The quoting rules for the schema name are the same as those for the
+        ``name`` parameter, in that quoting is applied for reserved words or
+        case-sensitive names; to enable unconditional quoting for the
+        schema name, specify the flag
+        ``quote_schema=True`` to the constructor, or use the
+        :class:`.quoted_name` construct to specify the name.
+
+    :param useexisting: Deprecated.  Use extend_existing.
+
+    :param \**kw: Additional keyword arguments not mentioned above are
+        dialect specific, and passed in the form ``<dialectname>_<argname>``.
+        See the documentation regarding an individual dialect at
+        :ref:`dialect_toplevel` for detail on documented arguments.

+          via keyword.
+
+          Names which contain no upper case characters
+          will be treated as case insensitive names, and will not be quoted
+          unless they are a reserved word.  Names with any number of upper

+          behavior applies even for databases which standardize upper
+          case names as case insensitive such as Oracle.
+
+          The name field may be omitted at construction time and applied
+          later, at any time before the Column is associated with a
+          :class:`.Table`.  This is to support convenient
+          usage within the :mod:`~sqlalchemy.ext.declarative` extension.
+
+        :param type\_: The column's type, indicated using an instance which
+          subclasses :class:`~sqlalchemy.types.TypeEngine`.  If no arguments
+          are required for the type, the class of the type can be sent

+          If the ``type`` is ``None`` or is omitted, it will first default to
+          the special type :class:`.NullType`.  If and when this
+          :class:`.Column` is made to refer to another column using
+          :class:`.ForeignKey` and/or :class:`.ForeignKeyConstraint`, the type
+          of the remote-referenced column will be copied to this column as
+          well, at the moment that the foreign key is resolved against that
+          remote :class:`.Column` object.
+
+          .. versionchanged:: 0.9.0
+            Support for propagation of type to a :class:`.Column` from its
+            :class:`.ForeignKey` object has been improved and should be
+            more reliable and timely.
+
+        :param \*args: Additional positional arguments include various
+          :class:`.SchemaItem` derived constructs which will be applied
+          as options to the column.  These include instances of
+          :class:`.Constraint`, :class:`.ForeignKey`, :class:`.ColumnDefault`,
+          and :class:`.Sequence`.  In some cases an equivalent keyword
+          argument is available such as ``server_default``, ``default``
+          and ``unique``.
+
+        :param autoincrement: This flag may be set to ``False`` to
+          indicate an integer primary key column that should not be
+          considered to be the "autoincrement" column, that is
+          the integer primary key column which generates values
+          implicitly upon INSERT and whose value is usually returned
+          via the DBAPI cursor.lastrowid attribute.   It defaults
+          to ``True`` to satisfy the common use case of a table
+          with a single integer primary key column.  If the table
+          has a composite primary key consisting of more than one
+          integer column, set this flag to True only on the
+          column that should be considered "autoincrement".
+
+          The setting *only* has an effect for columns which are:
+
+          * Integer derived (i.e. INT, SMALLINT, BIGINT).
+
+          * Part of the primary key
+
+          * Not refering to another column via :class:`.ForeignKey`, unless
+            the value is specified as ``'ignore_fk'``::
+
+                # turn on autoincrement for this column despite
+                # the ForeignKey()
+                Column('id', ForeignKey('other.id'),
+                            primary_key=True, autoincrement='ignore_fk')
+
+            It is typically not desirable to have "autoincrement" enabled
+            on such a column as its value intends to mirror that of a
+            primary key column elsewhere.
+
+          * have no server side or client side defaults (with the exception
+            of Postgresql SERIAL).
+
+          The setting has these two effects on columns that meet the
+          above criteria:
+
+          * DDL issued for the column will include database-specific
+            keywords intended to signify this column as an
+            "autoincrement" column, such as AUTO INCREMENT on MySQL,
+            SERIAL on Postgresql, and IDENTITY on MS-SQL.  It does
+            *not* issue AUTOINCREMENT for SQLite since this is a
+            special SQLite flag that is not required for autoincrementing
+            behavior.
+
+            .. seealso::
+
+                :ref:`sqlite_autoincrement`
+
+          * The column will be considered to be available as
+            cursor.lastrowid or equivalent, for those dialects which
+            "post fetch" newly inserted identifiers after a row has
+            been inserted (SQLite, MySQL, MS-SQL).  It does not have
+            any effect in this regard for databases that use sequences
+            to generate primary key identifiers (i.e. Firebird, Postgresql,
+            Oracle).
+
+          .. versionchanged:: 0.7.4
+              ``autoincrement`` accepts a special value ``'ignore_fk'``
+              to indicate that autoincrementing status regardless of foreign
+              key references.  This applies to certain composite foreign key
+              setups, such as the one demonstrated in the ORM documentation
+              at :ref:`post_update`.
+
+        :param default: A scalar, Python callable, or
+            :class:`.ColumnElement` expression representing the
+            *default value* for this column, which will be invoked upon insert
+            if this column is otherwise not specified in the VALUES clause of
+            the insert. This is a shortcut to using :class:`.ColumnDefault` as
+            a positional argument; see that class for full detail on the
+            structure of the argument.
+
+            Contrast this argument to ``server_default`` which creates a
+            default generator on the database side.
+
+        :param doc: optional String that can be used by the ORM or similar
+            to document attributes.   This attribute does not render SQL
+            comments (a future attribute 'comment' will achieve that).
+
+        :param key: An optional string identifier which will identify this
+            ``Column`` object on the :class:`.Table`. When a key is provided,
+            this is the only identifier referencing the ``Column`` within the
+            application, including ORM attribute mapping; the ``name`` field
+            is used only when rendering SQL.
+
+        :param index: When ``True``, indicates that the column is indexed.
+            This is a shortcut for using a :class:`.Index` construct on the
+            table. To specify indexes with explicit names or indexes that
+            contain multiple columns, use the :class:`.Index` construct
+            instead.
+
+        :param info: Optional data dictionary which will be populated into the
+            :attr:`.SchemaItem.info` attribute of this object.
+
+        :param nullable: If set to the default of ``True``, indicates the
+            column will be rendered as allowing NULL, else it's rendered as
+            NOT NULL. This parameter is only used when issuing CREATE TABLE
+            statements.
+
+        :param onupdate: A scalar, Python callable, or
+            :class:`~sqlalchemy.sql.expression.ClauseElement` representing a
+            default value to be applied to the column within UPDATE
+            statements, which wil be invoked upon update if this column is not
+            present in the SET clause of the update. This is a shortcut to
+            using :class:`.ColumnDefault` as a positional argument with
+            ``for_update=True``.
+
+        :param primary_key: If ``True``, marks this column as a primary key
+            column. Multiple columns can have this flag set to specify
+            composite primary keys. As an alternative, the primary key of a
+            :class:`.Table` can be specified via an explicit
+            :class:`.PrimaryKeyConstraint` object.
+
+        :param server_default: A :class:`.FetchedValue` instance, str, Unicode
+            or :func:`~sqlalchemy.sql.expression.text` construct representing
+            the DDL DEFAULT value for the column.
+
+            String types will be emitted as-is, surrounded by single quotes::
+
+                Column('x', Text, server_default="val")
+
+                x TEXT DEFAULT 'val'
+
+            A :func:`~sqlalchemy.sql.expression.text` expression will be
+            rendered as-is, without quotes::
+
+                Column('y', DateTime, server_default=text('NOW()'))
+
+                y DATETIME DEFAULT NOW()
+
+            Strings and text() will be converted into a
+            :class:`.DefaultClause` object upon initialization.
+
+            Use :class:`.FetchedValue` to indicate that an already-existing
+            column will generate a default value on the database side which
+            will be available to SQLAlchemy for post-fetch after inserts. This
+            construct does not specify any DDL and the implementation is left
+            to the database, such as via a trigger.
+
+        :param server_onupdate:   A :class:`.FetchedValue` instance
+             representing a database-side default generation function. This
+             indicates to SQLAlchemy that a newly generated value will be
+             available after updates. This construct does not specify any DDL
+             and the implementation is left to the database, such as via a
+             trigger.
+
+        :param quote: Force quoting of this column's name on or off,
+             corresponding to ``True`` or ``False``. When left at its default
+             of ``None``, the column identifier will be quoted according to
+             whether the name is case sensitive (identifiers with at least one
+             upper case character are treated as case sensitive), or if it's a
+             reserved word. This flag is only needed to force quoting of a
+             reserved word which is not known by the SQLAlchemy dialect.
+
+        :param unique: When ``True``, indicates that this column contains a
+             unique constraint, or if ``index`` is ``True`` as well, indicates
+             that the :class:`.Index` should be created with the unique flag.
+             To specify multiple columns in the constraint/index or to specify
+             an explicit name, use the :class:`.UniqueConstraint` or
+             :class:`.Index` constructs explicitly.
+
+        :param system: When ``True``, indicates this is a "system" column,
+             that is a column which is automatically made available by the
+             database, and should not be included in the columns list for a
+             ``CREATE TABLE`` statement.
+
+             For more elaborate scenarios where columns should be
+             conditionally rendered differently on different backends,
+             consider custom compilation rules for :class:`.CreateColumn`.

+    on any :class:`.Table` object; it is assigned a set of

+    the :paramref:`.Column.primary_key` flag::

+        )
+
+    The primary key of a :class:`.Table` can also be specified by using
+    a :class:`.PrimaryKeyConstraint` object explicitly; in this mode of usage,
+    the "name" of the constraint can also be specified, as well as other
+    options which may be recognized by dialects::

+    don't match the columns that were marked as ``primary_key=True``, if both
+    are present; in this case, the columns are taken strictly from the
+    :class:`.PrimaryKeyConstraint` declaration, and those columns otherwise
+    marked as ``primary_key=True`` are ignored.  This behavior is intended to

+       may raise an exception in a future release.
+
+    For the use case where specific options are to be specified on the
+    :class:`.PrimaryKeyConstraint`, but the usual style of using
+    ``primary_key=True`` flags is still desirable, an empty

+

+            :class:`.ForeignKeyConstraint` class, the :class:`.Index` class
+
+          * a string mnemonic for one of the known constraint classes;

+            primary key, index, check, and unique constraint, respectively.
+
+          * the string name of a user-defined "token" that can be used
+            to define new naming tokens.
+
+          The values associated with each "constraint class" or "constraint
+          mnemonic" key are string naming templates, such as
+          ``"uq_%(table_name)s_%(column_0_name)s"``,
+          which describe how the name should be composed.  The values
+          associated with user-defined "token" keys should be callables of the
+          form ``fn(constraint, table)``, which accepts the constraint/index
+          object and :class:`.Table` as arguments, returning a string
+          result.
+
+          The built-in names are as follows, some of which may only be
+          available for certain types of constraint:
+
+            * ``%(table_name)s`` - the name of the :class:`.Table` object
+              associated with the constraint.
+
+            * ``%(referred_table_name)s`` - the name of the :class:`.Table`
+              object associated with the referencing target of a
+              :class:`.ForeignKeyConstraint`.
+
+            * ``%(column_0_name)s`` - the name of the :class:`.Column` at
+              index position "0" within the constraint.
+
+            * ``%(column_0_label)s`` - the label of the :class:`.Column` at
+              index position "0", e.g. :attr:`.Column.label`
+
+            * ``%(column_0_key)s`` - the key of the :class:`.Column` at
+              index position "0", e.g. :attr:`.Column.key`
+
+            * ``%(referred_column_0_name)s`` - the name of a :class:`.Column`
+              at index position "0" referenced by a
+              :class:`.ForeignKeyConstraint`.
+
+            * ``%(constraint_name)s`` - a special key that refers to the
+              existing name given to the constraint.  When this key is
+              present, the :class:`.Constraint` object's existing name will be
+              replaced with one that is composed from template string that
+              uses this token. When this token is present, it is required that
+              the :class:`.Constraint` is given an expicit name ahead of time.
+
+            * user-defined: any additional token may be implemented by passing
+              it along with a ``fn(constraint, table)`` callable to the

+            )
+
+        The selectable produced by :meth:`.Join.alias` features the same
+        columns as that of the two individual selectables presented under
+        a single name - the individual columns are "auto-labeled", meaning
+        the ``.c.`` collection of the resulting :class:`.Alias` represents
+        the names of the individual columns using a
+        ``<tablename>_<columname>`` scheme::
+
+            j.c.table_a_id
+            j.c.table_b_a_id
+
+        :meth:`.Join.alias` also features an alternate
+        option for aliasing joins which produces no enclosing SELECT and
+        does not normally apply labels to the column names.  The
+        ``flat=True`` option will call :meth:`.FromClause.alias`
+        against the left and right sides individually.
+        Using this option, no new ``SELECT`` is produced;
+        we instead, from a construct as below::
+
+            j = table_a.join(table_b, table_a.c.id == table_b.c.a_id)
+            j = j.alias(flat=True)
+
+        we get a result like this::
+
+            table_a AS table_a_1 JOIN table_b AS table_b_1 ON
+            table_a_1.id = table_b_1.a_id
+
+        The ``flat=True`` argument is also propagated to the contained
+        selectables, so that a composite join such as::
+
+            j = table_a.join(
+                    table_b.join(table_c,
+                            table_b.c.id == table_c.c.b_id),
+                    table_b.c.a_id == table_a.c.id
+                ).alias(flat=True)
+
+        Will produce an expression like::
+
+            table_a AS table_a_1 JOIN (
+                    table_b AS table_b_1 JOIN table_c AS table_c_1
+                    ON table_b_1.id = table_c_1.b_id
+            ) ON table_a_1.id = table_b_1.a_id
+
+        The standalone :func:`~.expression.alias` function as well as the
+        base :meth:`.FromClause.alias` method also support the ``flat=True``
+        argument as a no-op, so that the argument can be passed to the
+        ``alias()`` method of any selectable.
+
+        .. versionadded:: 0.9.0 Added the ``flat=True`` option to create
+          "aliases" of joins without enclosing inside of a SELECT
+          subquery.

+            Due to a bug fix, this method has a slight
+            behavioral change as of version 0.7.3.
+            Prior to version 0.7.3, the FROM clause of
+            a :func:`.select` was calculated upfront and as new columns
+            were added; in 0.7.3 and later it's calculated
+            at compile time, fixing an issue regarding late binding
+            of columns to parent tables.  This changes the behavior of
+            :meth:`.Select.with_only_columns` in that FROM clauses no
+            longer represented in the new list are dropped,
+            but this behavior is more consistent in
+            that the FROM clauses are consistently derived from the
+            current columns clause.  The original intent of this method
+            is to allow trimming of the existing columns list to be fewer
+            columns than originally present; the use case of replacing
+            the columns list with an entirely different one hadn't
+            been anticipated until 0.7.3 was released; the usage
+            guidelines below illustrate how this should be done.
+
+        This method is exactly equivalent to as if the original
+        :func:`.select` had been called with the given columns
+        clause.   I.e. a statement::
+
+            s = select([table1.c.a, table1.c.b])
+            s = s.with_only_columns([table1.c.b])
+
+        should be exactly equivalent to::
+
+            s = select([table1.c.b])
+
+        This means that FROM clauses which are only derived
+        from the column list will be discarded if the new column
+        list no longer contains that FROM::
+
+            >>> table1 = table('t1', column('a'), column('b'))
+            >>> table2 = table('t2', column('a'), column('b'))
+            >>> s1 = select([table1.c.a, table2.c.b])
+            >>> print s1
+            SELECT t1.a, t2.b FROM t1, t2
+            >>> s2 = s1.with_only_columns([table2.c.b])
+            >>> print s2
+            SELECT t2.b FROM t1
+
+        The preferred way to maintain a specific FROM clause
+        in the construct, assuming it won't be represented anywhere
+        else (i.e. not in the WHERE clause, etc.) is to set it using
+        :meth:`.Select.select_from`::
+
+            >>> s1 = select([table1.c.a, table2.c.b]).\\
+            ...         select_from(table1.join(table2,
+            ...                 table1.c.a==table2.c.a))
+            >>> s2 = s1.with_only_columns([table2.c.b])
+            >>> print s2
+            SELECT t2.b FROM t1 JOIN t2 ON t1.a=t2.a
+
+        Care should also be taken to use the correct
+        set of column objects passed to :meth:`.Select.with_only_columns`.
+        Since the method is essentially equivalent to calling the
+        :func:`.select` construct in the first place with the given
+        columns, the columns passed to :meth:`.Select.with_only_columns`
+        should usually be a subset of those which were passed
+        to the :func:`.select` construct, not those which are available
+        from the ``.c`` collection of that :func:`.select`.  That
+        is::
+
+            s = select([table1.c.a, table1.c.b]).select_from(table1)
+            s = s.with_only_columns([table1.c.b])
+
+        and **not**::
+
+            # usually incorrect
+            s = s.with_only_columns([s.c.b])
+
+        The latter would produce the SQL::
+
+            SELECT b
+            FROM (SELECT t1.a AS a, t1.b AS b
+            FROM t1), t1
+
+        Since the :func:`.select` construct is essentially being
+        asked to select both from ``table1`` as well as itself.

+          If the DBAPI in use does not support Python unicode
+          (which is fewer and fewer these days), SQLAlchemy
+          will encode/decode the value, using the

+
+          When using a DBAPI that natively supports Python
+          unicode objects, this flag generally does not
+          need to be set.  For columns that are explicitly
+          intended to store non-ASCII data, the :class:`.Unicode`
+          or :class:`.UnicodeText`
+          types should be used regardless, which feature
+          the same behavior of ``convert_unicode`` but
+          also indicate an underlying column type that
+          directly supports unicode, such as ``NVARCHAR``.
+
+          For the extremely rare case that Python ``unicode``
+          is to be encoded/decoded by SQLAlchemy on a backend
+          that does natively support Python ``unicode``,
+          the value ``force`` can be passed here which will

+          requires that ``convert_unicode`` is set to ``force`` - otherwise,
+          SQLAlchemy is not guaranteed to handle the task of unicode
+          conversion.   Note that this flag adds significant performance
+          overhead to row-fetching operations for backends that already

+
+    The :class:`.Unicode` type is a :class:`.String` subclass
+    that assumes input and output as Python ``unicode`` data,
+    and in that regard is equivalent to the usage of the
+    ``convert_unicode`` flag with the :class:`.String` type.
+    However, unlike plain :class:`.String`, it also implies an
+    underlying column type that is explicitly supporting of non-ASCII
+    data, such as ``NVARCHAR`` on Oracle and SQL Server.
+    This can impact the output of ``CREATE TABLE`` statements
+    and ``CAST`` functions at the dialect level, and can
+    also affect the handling of bound parameters in some
+    specific DBAPI scenarios.
+
+    The encoding used by the :class:`.Unicode` type is usually
+    determined by the DBAPI itself; most modern DBAPIs
+    feature support for Python ``unicode`` objects as bound
+    values and result set values, and the encoding should
+    be configured as detailed in the notes for the target
+    DBAPI in the :ref:`dialect_toplevel` section.
+
+    For those DBAPIs which do not support, or are not configured
+    to accommodate Python ``unicode`` objects
+    directly, SQLAlchemy does the encoding and decoding
+    outside of the DBAPI.   The encoding in this scenario
+    is determined by the ``encoding`` flag passed to
+    :func:`.create_engine`.
+
+    When using the :class:`.Unicode` type, it is only appropriate
+    to pass Python ``unicode`` objects, and not plain ``str``.
+    If a plain ``str`` is passed under Python 2, a warning
+    is emitted.  If you notice your application emitting these warnings but
+    you're not sure of the source of them, the Python
+    ``warnings`` filter, documented at
+    http://docs.python.org/library/warnings.html,
+    can be used to turn these warnings into exceptions
+    which will illustrate a stack trace::
+
+      import warnings
+      warnings.simplefilter('error')
+
+    For an application that wishes to pass plain bytestrings
+    and Python ``unicode`` objects to the ``Unicode`` type
+    equally, the bytestrings must first be decoded into
+    unicode.  The recipe at :ref:`coerce_to_unicode` illustrates

+
+    The class-level "impl" attribute is required, and can reference any

+    can be used to provide different type classes based on the dialect
+    given; in this case, the "impl" variable can reference
+    ``TypeEngine`` as a placeholder.
+
+    Types that receive a Python type that isn't similar to the ultimate type
+    used may want to define the :meth:`TypeDecorator.coerce_compared_value`
+    method. This is used to give the expression system a hint when coercing
+    Python objects into bind parameters within expressions. Consider this
+    expression::
+
+        mytable.c.somecol + datetime.date(2009, 5, 15)
+
+    Above, if "somecol" is an ``Integer`` variant, it makes sense that
+    we're doing date arithmetic, where above is usually interpreted
+    by databases as adding a number of days to the given date.
+    The expression system does the right thing by not attempting to
+    coerce the "date()" value into an integer-oriented bind parameter.
+
+    However, in the case of ``TypeDecorator``, we are usually changing an
+    incoming Python type to something new - ``TypeDecorator`` by default will
+    "coerce" the non-typed side to be the same type as itself. Such as below,
+    we define an "epoch" type that stores a date value as an integer::
+
+        class MyEpochType(types.TypeDecorator):
+            impl = types.Integer
+
+            epoch = datetime.date(1970, 1, 1)
+
+            def process_bind_param(self, value, dialect):
+                return (value - self.epoch).days
+
+            def process_result_value(self, value, dialect):
+                return self.epoch + timedelta(days=value)
+
+    Our expression of ``somecol + date`` with the above type will coerce the

+"""Visitor/traversal interface and library functions.
+
+SQLAlchemy schema and expression constructs rely on a Python-centric
+version of the classic "visitor" pattern as the primary way in which
+they apply functionality.  The most common use of this pattern
+is statement compilation, where individual expression classes match
+up to rendering methods that produce a string result.   Beyond this,
+the visitor system is also used to inspect expressions for various
+information and patterns, as well as for usage in
+some kinds of expression transformation.  Other kinds of transformation
+use a non-visitor traversal system.
+
+For many examples of how the visit system is used, see the
+sqlalchemy.sql.util and the sqlalchemy.sql.compiler modules.
+For an introduction to clause adaption, see
+http://techspot.zzzeek.org/2008/01/23/expression-transformations/

+Nose test runner module.
+
+This script is a front-end to "nosetests" which
+installs SQLAlchemy's testing plugin into the local environment.
+
+The script is intended to be used by third-party dialects and extensions
+that run within SQLAlchemy's testing framework.    The runner can
+be invoked via::
+
+    python -m sqlalchemy.testing.runner
+
+The script is then essentially the same as the "nosetests" script, including
+all of the usual Nose options.   The test environment requires that a
+setup.cfg is locally present including various required options.
+
+Note that when using this runner, Nose's "coverage" plugin will not be
+able to provide coverage for SQLAlchemy itself, since SQLAlchemy is
+imported into sys.modules before coverage is started.   The special
+script sqla_nose.py is provided as a top-level script which loads the
+plugin in a special (somewhat hacky) way so that coverage against
+SQLAlchemy itself is possible.

-        ==========
-        
-        The Python SQL Toolkit and Object Relational Mapper
-        
-        Introduction
-        -------------
-        
-        SQLAlchemy is the Python SQL toolkit and Object Relational Mapper
-        that gives application developers the full power and
-        flexibility of SQL. SQLAlchemy provides a full suite
-        of well known enterprise-level persistence patterns,
-        designed for efficient and high-performing database
-        access, adapted into a simple and Pythonic domain
-        language.
-        
-        Major SQLAlchemy features include:
-        
-        * An industrial strength ORM, built 
-          from the core on the identity map, unit of work,
-          and data mapper patterns.   These patterns
-          allow transparent persistence of objects 
-          using a declarative configuration system.
-          Domain models
-          can be constructed and manipulated naturally,
-          and changes are synchronized with the
-          current transaction automatically.
-        * A relationally-oriented query system, exposing
-          the full range of SQL's capabilities 
-          explicitly, including joins, subqueries, 
-          correlation, and most everything else, 
-          in terms of the object model.
-          Writing queries with the ORM uses the same 
-          techniques of relational composition you use 
-          when writing SQL.  While you can drop into
-          literal SQL at any time, it's virtually never
-          needed.
-        * A comprehensive and flexible system 
-          of eager loading for related collections and objects.
-          Collections are cached within a session,
-          and can be loaded on individual access, all 
-          at once using joins, or by query per collection
-          across the full result set.
-        * A Core SQL construction system and DBAPI 
-          interaction layer.  The SQLAlchemy Core is
-          separate from the ORM and is a full database
-          abstraction layer in its own right, and includes
-          an extensible Python-based SQL expression 
-          language, schema metadata, connection pooling, 
-          type coercion, and custom types.
-        * All primary and foreign key constraints are 
-          assumed to be composite and natural.  Surrogate
-          integer primary keys are of course still the 
-          norm, but SQLAlchemy never assumes or hardcodes
-          to this model.
-        * Database introspection and generation.  Database
-          schemas can be "reflected" in one step into
-          Python structures representing database metadata;
-          those same structures can then generate 
-          CREATE statements right back out - all within
-          the Core, independent of the ORM.
-        
-        SQLAlchemy's philosophy:
-        
-        * SQL databases behave less and less like object
-          collections the more size and performance start to
-          matter; object collections behave less and less like
-          tables and rows the more abstraction starts to matter.
-          SQLAlchemy aims to accommodate both of these
-          principles.
-        * An ORM doesn't need to hide the "R".   A relational
-          database provides rich, set-based functionality
-          that should be fully exposed.   SQLAlchemy's
-          ORM provides an open-ended set of patterns
-          that allow a developer to construct a custom
-          mediation layer between a domain model and 
-          a relational schema, turning the so-called
-          "object relational impedance" issue into
-          a distant memory.
-        * The developer, in all cases, makes all decisions
-          regarding the design, structure, and naming conventions
-          of both the object model as well as the relational
-          schema.   SQLAlchemy only provides the means
-          to automate the execution of these decisions.
-        * With SQLAlchemy, there's no such thing as 
-          "the ORM generated a bad query" - you 
-          retain full control over the structure of 
-          queries, including how joins are organized,
-          how subqueries and correlation is used, what 
-          columns are requested.  Everything SQLAlchemy
-          does is ultimately the result of a developer-
-          initiated decision.
-        * Don't use an ORM if the problem doesn't need one.
-          SQLAlchemy consists of a Core and separate ORM
-          component.   The Core offers a full SQL expression
-          language that allows Pythonic construction 
-          of SQL constructs that render directly to SQL
-          strings for a target database, returning
-          result sets that are essentially enhanced DBAPI
-          cursors.
-        * Transactions should be the norm.  With SQLAlchemy's
-          ORM, nothing goes to permanent storage until
-          commit() is called.  SQLAlchemy encourages applications
-          to create a consistent means of delineating
-          the start and end of a series of operations.
-        * Never render a literal value in a SQL statement.
-          Bound parameters are used to the greatest degree
-          possible, allowing query optimizers to cache 
-          query plans effectively and making SQL injection
-          attacks a non-issue.

-        
-        ``cryptography`` is a package which provides cryptographic recipes and
-        primitives to Python developers.  Our goal is for it to be your "cryptographic
-        standard library". It supports Python 2.6-2.7, Python 3.2+, and PyPy.
-        
-        ``cryptography`` includes both high level recipes, and low level interfaces to
-        common cryptographic algorithms such as symmetric ciphers, message digests and
-        key derivation functions. For example, to encrypt something with
-        ``cryptography``'s high level symmetric encryption recipe:
-        
-        .. code-block:: pycon
-        
-            >>> from cryptography.fernet import Fernet
-            >>> # Put this somewhere safe!
-            >>> key = Fernet.generate_key()
-            >>> f = Fernet(key)
-            >>> token = f.encrypt(b"A really secret message. Not for prying eyes.")
-            >>> token
-            '...'
-            >>> f.decrypt(token)
-            'A really secret message. Not for prying eyes.'
-        
-        You can find more information in the `documentation`_.
-        
-        Discussion
-        ~~~~~~~~~~
-        
-        If you run into bugs, you can file them in our `issue tracker`_.
-        
-        We maintain a `cryptography-dev`_ mailing list for development discussion.
-        
-        You can also join ``#cryptography-dev`` on Freenode to ask questions or get
-        involved.

-Version: 1.2
-Summary: Ed25519 public-key signatures
-Home-page: https://github.com/warner/python-ed25519
-Author: Brian Warner
-Author-email: warner-python-ed25519@lothar.com
-License: MIT
-Description: Python bindings to the Ed25519 public-key signature system.
-        
-        This offers a comfortable python interface to a C implementation of the
-        Ed25519 public-key signature system (http://ed25519.cr.yp.to/), using the
-        portable 'ref' code from the 'SUPERCOP' benchmarking suite.
-        
-        This system provides high (128-bit) security, short (32-byte) keys, short
-        (64-byte) signatures, and fast (2-6ms) operation. Please see the README for
-        more details.

-Metadata-Version: 1.1
-Name: simplejson
-Version: 3.6.3
-Summary: Simple, fast, extensible JSON encoder/decoder for Python
-Home-page: http://github.com/simplejson/simplejson
-Author: Bob Ippolito
-Author-email: bob@redivi.com
-License: MIT License
-Description: simplejson is a simple, fast, complete, correct and extensible
-        JSON <http://json.org> encoder and decoder for Python 2.5+
-        and Python 3.3+.  It is pure Python code with no dependencies,
-        but includes an optional C extension for a serious speed boost.
-        
-        The latest documentation for simplejson can be read online here:
-        http://simplejson.readthedocs.org/
-        
-        simplejson is the externally maintained development version of the
-        json library included with Python 2.6 and Python 3.0, but maintains
-        backwards compatibility with Python 2.5.
-        
-        The encoder can be specialized to provide serialization in any kind of
-        situation, without any special support by the objects to be serialized
-        (somewhat like pickle). This is best done with the ``default`` kwarg
-        to dumps.
-        
-        The decoder can handle incoming JSON strings of any specified encoding
-        (UTF-8 by default). It can also be specialized to post-process JSON
-        objects with the ``object_hook`` or ``object_pairs_hook`` kwargs. This
-        is particularly useful for implementing protocols such as JSON-RPC
-        that have a richer type system than JSON itself.
-        
-        For those of you that have legacy systems to maintain, there is a
-        very old fork of simplejson in the `python2.2`_ branch that supports
-        Python 2.2. This is based off of a very old version of simplejson,
-        is not maintained, and should only be used as a last resort.

-r"""JSON (JavaScript Object Notation) <http://json.org> is a subset of
-JavaScript syntax (ECMA-262 3rd edition) used as a lightweight data
-interchange format.
-
-:mod:`simplejson` exposes an API familiar to users of the standard library
-:mod:`marshal` and :mod:`pickle` modules. It is the externally maintained
-version of the :mod:`json` library contained in Python 2.6, but maintains
-compatibility with Python 2.4 and Python 2.5 and (currently) has
-significant performance advantages, even without using the optional C
-extension for speedups.
-
-Encoding basic Python object hierarchies::
-
-    >>> import simplejson as json
-    >>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
-    '["foo", {"bar": ["baz", null, 1.0, 2]}]'
-    >>> print(json.dumps("\"foo\bar"))
-    "\"foo\bar"
-    >>> print(json.dumps(u'\u1234'))
-    "\u1234"
-    >>> print(json.dumps('\\'))
-    "\\"
-    >>> print(json.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True))
-    {"a": 0, "b": 0, "c": 0}
-    >>> from simplejson.compat import StringIO
-    >>> io = StringIO()
-    >>> json.dump(['streaming API'], io)
-    >>> io.getvalue()
-    '["streaming API"]'
-
-Compact encoding::
-
-    >>> import simplejson as json
-    >>> obj = [1,2,3,{'4': 5, '6': 7}]
-    >>> json.dumps(obj, separators=(',',':'), sort_keys=True)
-    '[1,2,3,{"4":5,"6":7}]'
-
-Pretty printing::
-
-    >>> import simplejson as json
-    >>> print(json.dumps({'4': 5, '6': 7}, sort_keys=True, indent='    '))
-    {
-        "4": 5,
-        "6": 7
-    }
-
-Decoding JSON::
-
-    >>> import simplejson as json
-    >>> obj = [u'foo', {u'bar': [u'baz', None, 1.0, 2]}]
-    >>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]') == obj
-    True
-    >>> json.loads('"\\"foo\\bar"') == u'"foo\x08ar'
-    True
-    >>> from simplejson.compat import StringIO
-    >>> io = StringIO('["streaming API"]')
-    >>> json.load(io)[0] == 'streaming API'
-    True
-
-Specializing JSON object decoding::
-
-    >>> import simplejson as json
-    >>> def as_complex(dct):
-    ...     if '__complex__' in dct:
-    ...         return complex(dct['real'], dct['imag'])
-    ...     return dct
-    ...
-    >>> json.loads('{"__complex__": true, "real": 1, "imag": 2}',
-    ...     object_hook=as_complex)
-    (1+2j)
-    >>> from decimal import Decimal
-    >>> json.loads('1.1', parse_float=Decimal) == Decimal('1.1')
-    True
-
-Specializing JSON object encoding::
-
-    >>> import simplejson as json
-    >>> def encode_complex(obj):
-    ...     if isinstance(obj, complex):
-    ...         return [obj.real, obj.imag]
-    ...     raise TypeError(repr(o) + " is not JSON serializable")
-    ...
-    >>> json.dumps(2 + 1j, default=encode_complex)
-    '[2.0, 1.0]'
-    >>> json.JSONEncoder(default=encode_complex).encode(2 + 1j)
-    '[2.0, 1.0]'
-    >>> ''.join(json.JSONEncoder(default=encode_complex).iterencode(2 + 1j))
-    '[2.0, 1.0]'
-
-
-Using simplejson.tool from the shell to validate and pretty-print::
-
-    $ echo '{"json":"obj"}' | python -m simplejson.tool
-    {
-        "json": "obj"

-    to cause an error.
-
-    If *check_circular* is false, then the circular reference check

-    result in an ``OverflowError`` (or worse).
-
-    If *allow_nan* is false, then it will be a ``ValueError`` to

-    :class:`tuple` (and subclasses) will be encoded as JSON arrays.
-
-    If *bigint_as_string* is true (default: ``False``), ints 2**53 and higher

-    sparingly.
-
-    If *int_as_string_bitcount* is a positive number (n), then int of size
-    greater than or equal to 2**n or lower than or equal to -2**n will be

-    in alphabetical order by key. This option takes precedence over

-Six is a Python 2 and 3 compatibility library.  It provides utility functions
-for smoothing over the differences between the Python versions with the goal of
-writing Python code that is compatible on both Python versions.  See the
-documentation for more information on what is provided.
-
-Six supports every Python version since 2.5.  It is contained in only one Python
-file, so it can be easily copied into your project. (The copyright and license
-notice must be retained.)
-
-Online documentation is at http://pythonhosted.org/six/.
-
-Bugs can be reported to http://bitbucket.org/gutworth/six.  The code can also be
-found there.
-
-For questions about six or porting in general, email the python-porting mailing
-list: http://mail.python.org/mailman/listinfo/python-porting

-.. dialect:: firebird
-    :name: Firebird
-
-Firebird Dialects
------------------
-
-Firebird offers two distinct dialects_ (not to be confused with a
-SQLAlchemy ``Dialect``):
-
-dialect 1
-  This is the old syntax and behaviour, inherited from Interbase pre-6.0.
-
-dialect 3
-  This is the newer and supported syntax, introduced in Interbase 6.0.
-
-The SQLAlchemy Firebird dialect detects these versions and
-adjusts its representation of SQL accordingly.  However,
-support for dialect 1 is not well tested and probably has
-incompatibilities.
-
-Locking Behavior
-----------------
-
-Firebird locks tables aggressively.  For this reason, a DROP TABLE may
-hang until other transactions are released.  SQLAlchemy does its best
-to release transactions as quickly as possible.  The most common cause
-of hanging transactions is a non-fully consumed result set, i.e.::
-
-    result = engine.execute("select * from table")
-    row = result.fetchone()
-    return
-
-Where above, the ``ResultProxy`` has not been fully consumed.  The
-connection will be returned to the pool and the transactional state
-rolled back once the Python garbage collector reclaims the objects
-which hold onto the connection, which often occurs asynchronously.
-The above use case can be alleviated by calling ``first()`` on the
-``ResultProxy`` which will fetch the first row and immediately close
-all remaining cursor/connection resources.
-
-RETURNING support
------------------
-
-Firebird 2.0 supports returning a result set from inserts, and 2.1
-extends that to deletes and updates. This is generically exposed by
-the SQLAlchemy ``returning()`` method, such as::
-
-    # INSERT..RETURNING
-    result = table.insert().returning(table.c.col1, table.c.col2).\\
-                   values(name='foo')
-    print result.fetchall()
-
-    # UPDATE..RETURNING
-    raises = empl.update().returning(empl.c.id, empl.c.salary).\\
-                  where(empl.c.sales>100).\\
-                  values(dict(salary=empl.c.salary * 1.1))
-    print raises.fetchall()

-.. dialect:: firebird+fdb
-    :name: fdb
-    :dbapi: pyodbc
-    :connectstring: firebird+fdb://user:password@host:port/path/to/db[?key=value&key=value...]
-    :url: http://pypi.python.org/pypi/fdb/
-
-    fdb is a kinterbasdb compatible DBAPI for Firebird.
-
-    .. versionadded:: 0.8 - Support for the fdb Firebird driver.
-
-    .. versionchanged:: 0.9 - The fdb dialect is now the default dialect
-       under the ``firebird://`` URL space, as ``fdb`` is now the official
-       Python driver for Firebird.
-
-Arguments
-----------
-
-The ``fdb`` dialect is based on the :mod:`sqlalchemy.dialects.firebird.kinterbasdb`
-dialect, however does not accept every argument that Kinterbasdb does.
-
-* ``enable_rowcount`` - True by default, setting this to False disables
-  the usage of "cursor.rowcount" with the
-  Kinterbasdb dialect, which SQLAlchemy ordinarily calls upon automatically
-  after any UPDATE or DELETE statement.   When disabled, SQLAlchemy's
-  ResultProxy will return -1 for result.rowcount.   The rationale here is
-  that Kinterbasdb requires a second round trip to the database when
-  .rowcount is called -  since SQLA's resultproxy automatically closes
-  the cursor after a non-result-returning statement, rowcount must be
-  called, if at all, before the result object is returned.   Additionally,
-  cursor.rowcount may not return correct results with older versions
-  of Firebird, and setting this flag to False will also cause the
-  SQLAlchemy ORM to ignore its usage. The behavior can also be controlled on a
-  per-execution basis using the ``enable_rowcount`` option with
-  :meth:`.Connection.execution_options`::
-
-      conn = engine.connect().execution_options(enable_rowcount=True)
-      r = conn.execute(stmt)
-      print r.rowcount
-
-* ``retaining`` - False by default.   Setting this to True will pass the
-  ``retaining=True`` keyword argument to the ``.commit()`` and ``.rollback()``
-  methods of the DBAPI connection, which can improve performance in some
-  situations, but apparently with significant caveats.
-  Please read the fdb and/or kinterbasdb DBAPI documentation in order to
-  understand the implications of this flag.
-
-  .. versionadded:: 0.8.2 - ``retaining`` keyword argument specifying
-     transaction retaining behavior - in 0.8 it defaults to ``True``
-     for backwards compatibility.
-
-  .. versionchanged:: 0.9.0 - the ``retaining`` flag defaults to ``False``.
-     In 0.8 it defaulted to ``True``.
-
-  .. seealso::
-
-    http://pythonhosted.org/fdb/usage-guide.html#retaining-transactions - information
-    on the "retaining" flag.

-.. dialect:: mssql
-    :name: Microsoft SQL Server
-
-
-Auto Increment Behavior
------------------------
-
-``IDENTITY`` columns are supported by using SQLAlchemy
-``schema.Sequence()`` objects. In other words::
-
-    from sqlalchemy import Table, Integer, Sequence, Column
-
-    Table('test', metadata,
-           Column('id', Integer,
-                  Sequence('blah',100,10), primary_key=True),
-           Column('name', String(20))
-         ).create(some_engine)
-
-would yield::
-
-   CREATE TABLE test (
-     id INTEGER NOT NULL IDENTITY(100,10) PRIMARY KEY,
-     name VARCHAR(20) NULL,
-     )
-
-Note that the ``start`` and ``increment`` values for sequences are
-optional and will default to 1,1.
-
-Implicit ``autoincrement`` behavior works the same in MSSQL as it
-does in other dialects and results in an ``IDENTITY`` column.
-
-* Support for ``SET IDENTITY_INSERT ON`` mode (automagic on / off for
-  ``INSERT`` s)
-
-* Support for auto-fetching of ``@@IDENTITY/@@SCOPE_IDENTITY()`` on
-  ``INSERT``
-
-Collation Support
------------------
-
-Character collations are supported by the base string types,
-specified by the string argument "collation"::
-
-    from sqlalchemy import VARCHAR
-    Column('login', VARCHAR(32, collation='Latin1_General_CI_AS'))
-
-When such a column is associated with a :class:`.Table`, the
-CREATE TABLE statement for this column will yield::
-
-    login VARCHAR(32) COLLATE Latin1_General_CI_AS NULL
-
-.. versionadded:: 0.8 Character collations are now part of the base string
-   types.
-
-LIMIT/OFFSET Support
---------------------
-
-MSSQL has no support for the LIMIT or OFFSET keysowrds. LIMIT is
-supported directly through the ``TOP`` Transact SQL keyword::
-
-    select.limit
-
-will yield::
-
-    SELECT TOP n
-
-If using SQL Server 2005 or above, LIMIT with OFFSET
-support is available through the ``ROW_NUMBER OVER`` construct.
-For versions below 2005, LIMIT with OFFSET usage will fail.
-
-Nullability
------------
-MSSQL has support for three levels of column nullability. The default
-nullability allows nulls and is explicit in the CREATE TABLE
-construct::
-
-    name VARCHAR(20) NULL
-
-If ``nullable=None`` is specified then no specification is made. In
-other words the database's configured default is used. This will
-render::
-
-    name VARCHAR(20)
-
-If ``nullable`` is ``True`` or ``False`` then the column will be
-``NULL` or ``NOT NULL`` respectively.
-
-Date / Time Handling
---------------------
-DATE and TIME are supported.   Bind parameters are converted
-to datetime.datetime() objects as required by most MSSQL drivers,
-and results are processed from strings if needed.
-The DATE and TIME types are not available for MSSQL 2005 and
-previous - if a server version below 2008 is detected, DDL
-for these types will be issued as DATETIME.
-
-.. _mssql_indexes:
-
-Clustered Index Support
------------------------
-
-The MSSQL dialect supports clustered indexes (and primary keys) via the
-``mssql_clustered`` option.  This option is available to :class:`.Index`,
-:class:`.UniqueConstraint`. and :class:`.PrimaryKeyConstraint`.
-
-To generate a clustered index::
-
-    Index("my_index", table.c.x, mssql_clustered=True)
-
-which renders the index as ``CREATE CLUSTERED INDEX my_index ON table (x)``.
-
-.. versionadded:: 0.8
-
-To generate a clustered primary key use::
-
-    Table('my_table', metadata,
-          Column('x', ...),
-          Column('y', ...),
-          PrimaryKeyConstraint("x", "y", mssql_clustered=True))
-
-which will render the table, for example, as::
-
-  CREATE TABLE my_table (x INTEGER NOT NULL, y INTEGER NOT NULL, PRIMARY KEY CLUSTERED (x, y))
-
-Similarly, we can generate a clustered unique constraint using::
-
-    Table('my_table', metadata,
-          Column('x', ...),
-          Column('y', ...),
-          PrimaryKeyConstraint("x"),
-          UniqueConstraint("y", mssql_clustered=True),
-          )
-
-  .. versionadded:: 0.9.2
-
-MSSQL-Specific Index Options
------------------------------
-
-In addition to clustering, the MSSQL dialect supports other special options
-for :class:`.Index`.
-
-INCLUDE
-^^^^^^^
-
-The ``mssql_include`` option renders INCLUDE(colname) for the given string names::
-
-    Index("my_index", table.c.x, mssql_include=['y'])
-
-would render the index as ``CREATE INDEX my_index ON table (x) INCLUDE (y)``
-
-.. versionadded:: 0.8
-
-Index ordering
-^^^^^^^^^^^^^^
-
-Index ordering is available via functional expressions, such as::
-
-    Index("my_index", table.c.x.desc())
-
-would render the index as ``CREATE INDEX my_index ON table (x DESC)``
-
-.. versionadded:: 0.8
-
-.. seealso::
-
-    :ref:`schema_indexes_functional`
-
-Compatibility Levels
---------------------
-MSSQL supports the notion of setting compatibility levels at the
-database level. This allows, for instance, to run a database that
-is compatible with SQL2000 while running on a SQL2005 database
-server. ``server_version_info`` will always return the database
-server version information (in this case SQL2005) and not the
-compatibility level information. Because of this, if running under
-a backwards compatibility mode SQAlchemy may attempt to use T-SQL
-statements that are unable to be parsed by the database server.
-
-Triggers
---------
-
-SQLAlchemy by default uses OUTPUT INSERTED to get at newly
-generated primary key values via IDENTITY columns or other
-server side defaults.   MS-SQL does not
-allow the usage of OUTPUT INSERTED on tables that have triggers.
-To disable the usage of OUTPUT INSERTED on a per-table basis,
-specify ``implicit_returning=False`` for each :class:`.Table`
-which has triggers::
-
-    Table('mytable', metadata,
-        Column('id', Integer, primary_key=True),
-        # ...,
-        implicit_returning=False
-    )
-
-Declarative form::
-
-    class MyClass(Base):
-        # ...
-        __table_args__ = {'implicit_returning':False}
-
-
-This option can also be specified engine-wide using the
-``implicit_returning=False`` argument on :func:`.create_engine`.
-
-Enabling Snapshot Isolation
----------------------------
-
-Not necessarily specific to SQLAlchemy, SQL Server has a default transaction
-isolation mode that locks entire tables, and causes even mildly concurrent
-applications to have long held locks and frequent deadlocks.
-Enabling snapshot isolation for the database as a whole is recommended
-for modern levels of concurrency support.  This is accomplished via the
-following ALTER DATABASE commands executed at the SQL prompt::
-
-    ALTER DATABASE MyDatabase SET ALLOW_SNAPSHOT_ISOLATION ON
-
-    ALTER DATABASE MyDatabase SET READ_COMMITTED_SNAPSHOT ON
-
-Background on SQL Server snapshot isolation is available at
-http://msdn.microsoft.com/en-us/library/ms175095.aspx.
-
-Known Issues
-------------
-
-* No support for more than one ``IDENTITY`` column per table
-* reflection of indexes does not work with versions older than
-  SQL Server 2005

-
-Execution Modes
----------------
-
-mxODBC features two styles of statement execution, using the
-``cursor.execute()`` and ``cursor.executedirect()`` methods (the second being
-an extension to the DBAPI specification). The former makes use of a particular
-API call specific to the SQL Server Native Client ODBC driver known
-SQLDescribeParam, while the latter does not.
-
-mxODBC apparently only makes repeated use of a single prepared statement
-when SQLDescribeParam is used. The advantage to prepared statement reuse is
-one of performance. The disadvantage is that SQLDescribeParam has a limited
-set of scenarios in which bind parameters are understood, including that they
-cannot be placed within the argument lists of function calls, anywhere outside
-the FROM, or even within subqueries within the FROM clause - making the usage
-of bind parameters within SELECT statements impossible for all but the most
-simplistic statements.
-
-For this reason, the mxODBC dialect uses the "native" mode by default only for
-INSERT, UPDATE, and DELETE statements, and uses the escaped string mode for
-all other statements.
-
-This behavior can be controlled via
-:meth:`~sqlalchemy.sql.expression.Executable.execution_options` using the
-``native_odbc_execute`` flag with a value of ``True`` or ``False``, where a
-value of ``True`` will unconditionally use native bind parameters and a value
-of ``False`` will unconditionally use string-escaped parameters.

-
-Additional Connection Examples
--------------------------------
-
-Examples of pyodbc connection string URLs:
-
-* ``mssql+pyodbc://mydsn`` - connects using the specified DSN named ``mydsn``.
-  The connection string that is created will appear like::
-
-    dsn=mydsn;Trusted_Connection=Yes
-
-* ``mssql+pyodbc://user:pass@mydsn`` - connects using the DSN named
-  ``mydsn`` passing in the ``UID`` and ``PWD`` information. The
-  connection string that is created will appear like::
-
-    dsn=mydsn;UID=user;PWD=pass
-
-* ``mssql+pyodbc://user:pass@mydsn/?LANGUAGE=us_english`` - connects
-  using the DSN named ``mydsn`` passing in the ``UID`` and ``PWD``
-  information, plus the additional connection configuration option
-  ``LANGUAGE``. The connection string that is created will appear
-  like::
-
-    dsn=mydsn;UID=user;PWD=pass;LANGUAGE=us_english
-
-* ``mssql+pyodbc://user:pass@host/db`` - connects using a connection
-  that would appear like::
-
-    DRIVER={SQL Server};Server=host;Database=db;UID=user;PWD=pass
-
-* ``mssql+pyodbc://user:pass@host:123/db`` - connects using a connection
-  string which includes the port
-  information using the comma syntax. This will create the following
-  connection string::
-
-    DRIVER={SQL Server};Server=host,123;Database=db;UID=user;PWD=pass
-
-* ``mssql+pyodbc://user:pass@host/db?port=123`` - connects using a connection
-  string that includes the port
-  information as a separate ``port`` keyword. This will create the
-  following connection string::
-
-    DRIVER={SQL Server};Server=host;Database=db;UID=user;PWD=pass;port=123
-
-* ``mssql+pyodbc://user:pass@host/db?driver=MyDriver`` - connects using a connection
-  string that includes a custom
-  ODBC driver name.  This will create the following connection string::
-
-    DRIVER={MyDriver};Server=host;Database=db;UID=user;PWD=pass
-
-If you require a connection string that is outside the options
-presented above, use the ``odbc_connect`` keyword to pass in a
-urlencoded connection string. What gets passed in will be urldecoded
-and passed directly.
-
-For example::
-
-    mssql+pyodbc:///?odbc_connect=dsn%3Dmydsn%3BDatabase%3Ddb
-
-would create the following connection string::
-
-    dsn=mydsn;Database=db
-
-Encoding your connection string can be easily accomplished through
-the python shell. For example::
-
-    >>> import urllib
-    >>> urllib.quote_plus('dsn=mydsn;Database=db')
-    'dsn%3Dmydsn%3BDatabase%3Ddb'
-
-Unicode Binds
--------------
-
-The current state of PyODBC on a unix backend with FreeTDS and/or
-EasySoft is poor regarding unicode; different OS platforms and versions of UnixODBC
-versus IODBC versus FreeTDS/EasySoft versus PyODBC itself dramatically
-alter how strings are received.  The PyODBC dialect attempts to use all the information
-it knows to determine whether or not a Python unicode literal can be
-passed directly to the PyODBC driver or not; while SQLAlchemy can encode
-these to bytestrings first, some users have reported that PyODBC mis-handles
-bytestrings for certain encodings and requires a Python unicode object,
-while the author has observed widespread cases where a Python unicode
-is completely misinterpreted by PyODBC, particularly when dealing with
-the information schema tables used in table reflection, and the value
-must first be encoded to a bytestring.
-
-It is for this reason that whether or not unicode literals for bound
-parameters be sent to PyODBC can be controlled using the
-``supports_unicode_binds`` parameter to ``create_engine()``.  When
-left at its default of ``None``, the PyODBC dialect will use its
-best guess as to whether or not the driver deals with unicode literals
-well.  When ``False``, unicode literals will be encoded first, and when
-``True`` unicode literals will be passed straight through.  This is an interim
-flag that hopefully should not be needed when the unicode situation stabilizes
-for unix + PyODBC.

-.. dialect:: mysql
-    :name: MySQL
-
-Supported Versions and Features
--------------------------------
-
-SQLAlchemy supports MySQL starting with version 4.1 through modern releases.
-However, no heroic measures are taken to work around major missing
-SQL features - if your server version does not support sub-selects, for
-example, they won't work in SQLAlchemy either.
-
-See the official MySQL documentation for detailed information about features
-supported in any given server release.
-
-.. _mysql_connection_timeouts:
-
-Connection Timeouts
--------------------
-
-MySQL features an automatic connection close behavior, for connections that have
-been idle for eight hours or more.   To circumvent having this issue, use the
-``pool_recycle`` option which controls the maximum age of any connection::
-
-    engine = create_engine('mysql+mysqldb://...', pool_recycle=3600)
-
-.. _mysql_storage_engines:
-
-CREATE TABLE arguments including Storage Engines
-------------------------------------------------
-
-MySQL's CREATE TABLE syntax includes a wide array of special options,
-including ``ENGINE``, ``CHARSET``, ``MAX_ROWS``, ``ROW_FORMAT``, ``INSERT_METHOD``, and many more.
-To accommodate the rendering of these arguments, specify the form
-``mysql_argument_name="value"``.  For example, to specify a table with
-``ENGINE`` of ``InnoDB``, ``CHARSET`` of ``utf8``, and ``KEY_BLOCK_SIZE`` of ``1024``::
-
-  Table('mytable', metadata,
-        Column('data', String(32)),
-        mysql_engine='InnoDB',
-        mysql_charset='utf8',
-        mysql_key_block_size="1024"
-       )
-
-The MySQL dialect will normally transfer any keyword specified as ``mysql_keyword_name``
-to be rendered as ``KEYWORD_NAME`` in the ``CREATE TABLE`` statement.  A handful
-of these names will render with a space instead of an underscore; to support this,
-the MySQL dialect has awareness of these particular names, which include
-``DATA DIRECTORY`` (e.g. ``mysql_data_directory``), ``CHARACTER SET`` (e.g.
-``mysql_character_set``) and ``INDEX DIRECTORY`` (e.g. ``mysql_index_directory``).
-
-The most common argument is ``mysql_engine``, which refers to the storage engine
-for the table.  Historically, MySQL server installations would default
-to ``MyISAM`` for this value, although newer versions may be defaulting
-to ``InnoDB``.  The ``InnoDB`` engine is typically preferred for its support
-of transactions and foreign keys.
-
-A :class:`.Table` that is created in a MySQL database with a storage engine
-of ``MyISAM`` will be essentially non-transactional, meaning any INSERT/UPDATE/DELETE
-statement referring to this table will be invoked as autocommit.   It also will have no
-support for foreign key constraints; while the ``CREATE TABLE`` statement
-accepts foreign key options, when using the ``MyISAM`` storage engine these
-arguments are discarded.  Reflecting such a table will also produce no
-foreign key constraint information.
-
-For fully atomic transactions as well as support for foreign key
-constraints, all participating ``CREATE TABLE`` statements must specify a
-transactional engine, which in the vast majority of cases is ``InnoDB``.
-
-.. seealso::
-
-    `The InnoDB Storage Engine
-    <http://dev.mysql.com/doc/refman/5.0/en/innodb-storage-engine.html>`_ -
-    on the MySQL website.
-
-Case Sensitivity and Table Reflection
--------------------------------------
-
-MySQL has inconsistent support for case-sensitive identifier
-names, basing support on specific details of the underlying
-operating system. However, it has been observed that no matter
-what case sensitivity behavior is present, the names of tables in
-foreign key declarations are *always* received from the database
-as all-lower case, making it impossible to accurately reflect a
-schema where inter-related tables use mixed-case identifier names.
-
-Therefore it is strongly advised that table names be declared as
-all lower case both within SQLAlchemy as well as on the MySQL
-database itself, especially if database reflection features are
-to be used.
-
-Transaction Isolation Level
----------------------------
-
-:func:`.create_engine` accepts an ``isolation_level``
-parameter which results in the command ``SET SESSION
-TRANSACTION ISOLATION LEVEL <level>`` being invoked for
-every new connection. Valid values for this parameter are
-``READ COMMITTED``, ``READ UNCOMMITTED``,
-``REPEATABLE READ``, and ``SERIALIZABLE``::
-
-    engine = create_engine(
-                    "mysql://scott:tiger@localhost/test",
-                    isolation_level="READ UNCOMMITTED"
-                )
-
-.. versionadded:: 0.7.6
-
-AUTO_INCREMENT Behavior
------------------------
-
-When creating tables, SQLAlchemy will automatically set ``AUTO_INCREMENT`` on
-the first :class:`.Integer` primary key column which is not marked as a foreign key::
-
-  >>> t = Table('mytable', metadata,
-  ...   Column('mytable_id', Integer, primary_key=True)
-  ... )
-  >>> t.create()
-  CREATE TABLE mytable (
-          id INTEGER NOT NULL AUTO_INCREMENT,
-          PRIMARY KEY (id)
-  )
-
-You can disable this behavior by passing ``False`` to the :paramref:`~.Column.autoincrement`
-argument of :class:`.Column`.  This flag can also be used to enable
-auto-increment on a secondary column in a multi-column key for some storage
-engines::
-
-  Table('mytable', metadata,
-        Column('gid', Integer, primary_key=True, autoincrement=False),
-        Column('id', Integer, primary_key=True)
-       )
-
-Ansi Quoting Style
-------------------
-
-MySQL features two varieties of identifier "quoting style", one using
-backticks and the other using quotes, e.g. ```some_identifier```  vs.
-``"some_identifier"``.   All MySQL dialects detect which version
-is in use by checking the value of ``sql_mode`` when a connection is first
-established with a particular :class:`.Engine`.  This quoting style comes
-into play when rendering table and column names as well as when reflecting
-existing database structures.  The detection is entirely automatic and
-no special configuration is needed to use either quoting style.
-
-.. versionchanged:: 0.6 detection of ANSI quoting style is entirely automatic,
-   there's no longer any end-user ``create_engine()`` options in this regard.
-
-MySQL SQL Extensions
---------------------
-
-Many of the MySQL SQL extensions are handled through SQLAlchemy's generic
-function and operator support::
-
-  table.select(table.c.password==func.md5('plaintext'))
-  table.select(table.c.username.op('regexp')('^[a-d]'))
-
-And of course any valid MySQL statement can be executed as a string as well.
-
-Some limited direct support for MySQL extensions to SQL is currently
-available.
-
-* SELECT pragma::
-
-    select(..., prefixes=['HIGH_PRIORITY', 'SQL_SMALL_RESULT'])
-
-* UPDATE with LIMIT::
-
-    update(..., mysql_limit=10)
-
-rowcount Support
-----------------
-
-SQLAlchemy standardizes the DBAPI ``cursor.rowcount`` attribute to be the
-usual definition of "number of rows matched by an UPDATE or DELETE" statement.
-This is in contradiction to the default setting on most MySQL DBAPI drivers,
-which is "number of rows actually modified/deleted".  For this reason, the
-SQLAlchemy MySQL dialects always set the ``constants.CLIENT.FOUND_ROWS`` flag,
-or whatever is equivalent for the DBAPI in use, on connect, unless the flag value
-is overridden using DBAPI-specific options
-(such as ``client_flag`` for the MySQL-Python driver, ``found_rows`` for the
-OurSQL driver).
-
-See also:
-
-:attr:`.ResultProxy.rowcount`
-
-
-CAST Support
-------------
-
-MySQL documents the CAST operator as available in version 4.0.2.  When using the
-SQLAlchemy :func:`.cast` function, SQLAlchemy
-will not render the CAST token on MySQL before this version, based on server version
-detection, instead rendering the internal expression directly.
-
-CAST may still not be desirable on an early MySQL version post-4.0.2, as it didn't
-add all datatype support until 4.1.1.   If your application falls into this
-narrow area, the behavior of CAST can be controlled using the
-:ref:`sqlalchemy.ext.compiler_toplevel` system, as per the recipe below::
-
-    from sqlalchemy.sql.expression import Cast
-    from sqlalchemy.ext.compiler import compiles
-
-    @compiles(Cast, 'mysql')
-    def _check_mysql_version(element, compiler, **kw):
-        if compiler.dialect.server_version_info < (4, 1, 0):
-            return compiler.process(element.clause, **kw)
-        else:
-            return compiler.visit_cast(element, **kw)
-
-The above function, which only needs to be declared once
-within an application, overrides the compilation of the
-:func:`.cast` construct to check for version 4.1.0 before
-fully rendering CAST; else the internal element of the
-construct is rendered directly.
-
-
-.. _mysql_indexes:
-
-MySQL Specific Index Options
-----------------------------
-
-MySQL-specific extensions to the :class:`.Index` construct are available.
-
-Index Length
-~~~~~~~~~~~~~
-
-MySQL provides an option to create index entries with a certain length, where
-"length" refers to the number of characters or bytes in each value which will
-become part of the index. SQLAlchemy provides this feature via the
-``mysql_length`` parameter::
-
-    Index('my_index', my_table.c.data, mysql_length=10)
-
-    Index('a_b_idx', my_table.c.a, my_table.c.b, mysql_length={'a': 4, 'b': 9})
-
-Prefix lengths are given in characters for nonbinary string types and in bytes
-for binary string types. The value passed to the keyword argument *must* be
-either an integer (and, thus, specify the same prefix length value for all
-columns of the index) or a dict in which keys are column names and values are
-prefix length values for corresponding columns. MySQL only allows a length for
-a column of an index if it is for a CHAR, VARCHAR, TEXT, BINARY, VARBINARY and
-BLOB.
-
-.. versionadded:: 0.8.2 ``mysql_length`` may now be specified as a dictionary
-   for use with composite indexes.
-
-Index Types
-~~~~~~~~~~~~~
-
-Some MySQL storage engines permit you to specify an index type when creating
-an index or primary key constraint. SQLAlchemy provides this feature via the
-``mysql_using`` parameter on :class:`.Index`::
-
-    Index('my_index', my_table.c.data, mysql_using='hash')
-
-As well as the ``mysql_using`` parameter on :class:`.PrimaryKeyConstraint`::
-
-    PrimaryKeyConstraint("data", mysql_using='hash')
-
-The value passed to the keyword argument will be simply passed through to the
-underlying CREATE INDEX or PRIMARY KEY clause, so it *must* be a valid index
-type for your MySQL storage engine.
-
-More information can be found at:
-
-http://dev.mysql.com/doc/refman/5.0/en/create-index.html
-
-http://dev.mysql.com/doc/refman/5.0/en/create-table.html
-
-.. _mysql_foreign_keys:
-
-MySQL Foreign Keys
-------------------
-
-MySQL's behavior regarding foreign keys has some important caveats.
-
-Foreign Key Arguments to Avoid
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-MySQL does not support the foreign key arguments "DEFERRABLE", "INITIALLY",
-or "MATCH".  Using the ``deferrable`` or ``initially`` keyword argument with
-:class:`.ForeignKeyConstraint` or :class:`.ForeignKey` will have the effect of these keywords being
-rendered in a DDL expression, which will then raise an error on MySQL.
-In order to use these keywords on a foreign key while having them ignored
-on a MySQL backend, use a custom compile rule::
-
-    from sqlalchemy.ext.compiler import compiles
-    from sqlalchemy.schema import ForeignKeyConstraint
-
-    @compiles(ForeignKeyConstraint, "mysql")
-    def process(element, compiler, **kw):
-        element.deferrable = element.initially = None
-        return compiler.visit_foreign_key_constraint(element, **kw)
-
-.. versionchanged:: 0.9.0 - the MySQL backend no longer silently ignores
-   the ``deferrable`` or ``initially`` keyword arguments of :class:`.ForeignKeyConstraint`
-   and :class:`.ForeignKey`.
-
-The "MATCH" keyword is in fact more insidious, and is explicitly disallowed
-by SQLAlchemy in conjunction with the MySQL backend.  This argument is silently
-ignored by MySQL, but in addition has the effect of ON UPDATE and ON DELETE options
-also being ignored by the backend.   Therefore MATCH should never be used with the
-MySQL backend; as is the case with DEFERRABLE and INITIALLY, custom compilation
-rules can be used to correct a MySQL ForeignKeyConstraint at DDL definition time.
-
-.. versionadded:: 0.9.0 - the MySQL backend will raise a :class:`.CompileError`
-   when the ``match`` keyword is used with :class:`.ForeignKeyConstraint`
-   or :class:`.ForeignKey`.
-
-Reflection of Foreign Key Constraints
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Not all MySQL storage engines support foreign keys.  When using the
-very common ``MyISAM`` MySQL storage engine, the information loaded by table
-reflection will not include foreign keys.  For these tables, you may supply a
-:class:`~sqlalchemy.ForeignKeyConstraint` at reflection time::
-
-  Table('mytable', metadata,
-        ForeignKeyConstraint(['other_id'], ['othertable.other_id']),
-        autoload=True
-       )
-
-.. seealso::

-Unicode
--------
-
-MySQLdb requires a "charset" parameter to be passed in order for it
-to handle non-ASCII characters correctly.   When this parameter is passed,
-MySQLdb will also implicitly set the "use_unicode" flag to true, which means
-that it will return Python unicode objects instead of bytestrings.
-However, SQLAlchemy's decode process, when C extensions are enabled,
-is orders of magnitude faster than that of MySQLdb as it does not call into
-Python functions to do so.  Therefore, the **recommended URL to use for
-unicode** will include both charset and use_unicode=0::
-
-    create_engine("mysql+mysqldb://user:pass@host/dbname?charset=utf8&use_unicode=0")
-
-As of this writing, MySQLdb only runs on Python 2.   It is not known how
-MySQLdb behaves on Python 3 as far as unicode decoding.
-
-
-Known Issues
--------------
-
-MySQL-python version 1.2.2 has a serious memory leak related
-to unicode conversion, a feature which is disabled via ``use_unicode=0``.
-It is strongly advised to use the latest version of MySQL-Python.

-"""
-.. dialect:: oracle
-    :name: Oracle
-
-    Oracle version 8 through current (11g at the time of this writing) are supported.
-
-Connect Arguments
------------------
-
-The dialect supports several :func:`~sqlalchemy.create_engine()` arguments which
-affect the behavior of the dialect regardless of driver in use.
-
-* ``use_ansi`` - Use ANSI JOIN constructs (see the section on Oracle 8).  Defaults
-  to ``True``.  If ``False``, Oracle-8 compatible constructs are used for joins.
-
-* ``optimize_limits`` - defaults to ``False``. see the section on LIMIT/OFFSET.
-
-* ``use_binds_for_limits`` - defaults to ``True``.  see the section on LIMIT/OFFSET.
-
-Auto Increment Behavior
------------------------
-
-SQLAlchemy Table objects which include integer primary keys are usually assumed to have
-"autoincrementing" behavior, meaning they can generate their own primary key values upon
-INSERT.  Since Oracle has no "autoincrement" feature, SQLAlchemy relies upon sequences
-to produce these values.   With the Oracle dialect, *a sequence must always be explicitly
-specified to enable autoincrement*.  This is divergent with the majority of documentation
-examples which assume the usage of an autoincrement-capable database.   To specify sequences,
-use the sqlalchemy.schema.Sequence object which is passed to a Column construct::
-
-  t = Table('mytable', metadata,
-        Column('id', Integer, Sequence('id_seq'), primary_key=True),
-        Column(...), ...
-  )
-
-This step is also required when using table reflection, i.e. autoload=True::
-
-  t = Table('mytable', metadata,
-        Column('id', Integer, Sequence('id_seq'), primary_key=True),
-        autoload=True
-  )
-
-Identifier Casing
------------------
-
-In Oracle, the data dictionary represents all case insensitive identifier names
-using UPPERCASE text.   SQLAlchemy on the other hand considers an all-lower case identifier
-name to be case insensitive.   The Oracle dialect converts all case insensitive identifiers
-to and from those two formats during schema level communication, such as reflection of
-tables and indexes.   Using an UPPERCASE name on the SQLAlchemy side indicates a
-case sensitive identifier, and SQLAlchemy will quote the name - this will cause mismatches
-against data dictionary data received from Oracle, so unless identifier names have been
-truly created as case sensitive (i.e. using quoted names), all lowercase names should be
-used on the SQLAlchemy side.
-
-
-LIMIT/OFFSET Support
---------------------
-
-Oracle has no support for the LIMIT or OFFSET keywords.  SQLAlchemy uses
-a wrapped subquery approach in conjunction with ROWNUM.  The exact methodology
-is taken from
-http://www.oracle.com/technology/oramag/oracle/06-sep/o56asktom.html .
-
-There are two options which affect its behavior:
-
-* the "FIRST ROWS()" optimization keyword is not used by default.  To enable the usage of this
-  optimization directive, specify ``optimize_limits=True`` to :func:`.create_engine`.
-* the values passed for the limit/offset are sent as bound parameters.   Some users have observed
-  that Oracle produces a poor query plan when the values are sent as binds and not
-  rendered literally.   To render the limit/offset values literally within the SQL
-  statement, specify ``use_binds_for_limits=False`` to :func:`.create_engine`.
-
-Some users have reported better performance when the entirely different approach of a
-window query is used, i.e. ROW_NUMBER() OVER (ORDER BY), to provide LIMIT/OFFSET (note
-that the majority of users don't observe this).  To suit this case the
-method used for LIMIT/OFFSET can be replaced entirely.  See the recipe at
-http://www.sqlalchemy.org/trac/wiki/UsageRecipes/WindowFunctionsByDefault
-which installs a select compiler that overrides the generation of limit/offset with
-a window function.
-
-.. _oracle_returning:
-
-RETURNING Support
------------------
-
-The Oracle database supports a limited form of RETURNING, in order to retrieve result
-sets of matched rows from INSERT, UPDATE and DELETE statements.  Oracle's
-RETURNING..INTO syntax only supports one row being returned, as it relies upon
-OUT parameters in order to function.  In addition, supported DBAPIs have further
-limitations (see :ref:`cx_oracle_returning`).
-
-SQLAlchemy's "implicit returning" feature, which employs RETURNING within an INSERT
-and sometimes an UPDATE statement in order to fetch newly generated primary key values
-and other SQL defaults and expressions, is normally enabled on the Oracle
-backend.  By default, "implicit returning" typically only fetches the value of a
-single ``nextval(some_seq)`` expression embedded into an INSERT in order to increment
-a sequence within an INSERT statement and get the value back at the same time.
-To disable this feature across the board, specify ``implicit_returning=False`` to
-:func:`.create_engine`::
-
-    engine = create_engine("oracle://scott:tiger@dsn", implicit_returning=False)
-
-Implicit returning can also be disabled on a table-by-table basis as a table option::
-
-    # Core Table
-    my_table = Table("my_table", metadata, ..., implicit_returning=False)
-
-
-    # declarative
-    class MyClass(Base):
-        __tablename__ = 'my_table'
-        __table_args__ = {"implicit_returning": False}
-
-.. seealso::
-
-    :ref:`cx_oracle_returning` - additional cx_oracle-specific restrictions on implicit returning.
-
-ON UPDATE CASCADE
------------------
-
-Oracle doesn't have native ON UPDATE CASCADE functionality.  A trigger based solution
-is available at http://asktom.oracle.com/tkyte/update_cascade/index.html .
-
-When using the SQLAlchemy ORM, the ORM has limited ability to manually issue
-cascading updates - specify ForeignKey objects using the
-"deferrable=True, initially='deferred'" keyword arguments,
-and specify "passive_updates=False" on each relationship().
-
-Oracle 8 Compatibility
-----------------------
-
-When Oracle 8 is detected, the dialect internally configures itself to the following
-behaviors:
-
-* the use_ansi flag is set to False.  This has the effect of converting all
-  JOIN phrases into the WHERE clause, and in the case of LEFT OUTER JOIN
-  makes use of Oracle's (+) operator.
-
-* the NVARCHAR2 and NCLOB datatypes are no longer generated as DDL when
-  the :class:`~sqlalchemy.types.Unicode` is used - VARCHAR2 and CLOB are issued
-  instead.   This because these types don't seem to work correctly on Oracle 8
-  even though they are available.  The :class:`~sqlalchemy.types.NVARCHAR`
-  and :class:`~sqlalchemy.dialects.oracle.NCLOB` types will always generate NVARCHAR2 and NCLOB.
-
-* the "native unicode" mode is disabled when using cx_oracle, i.e. SQLAlchemy
-  encodes all Python unicode objects to "string" before passing in as bind parameters.
-
-Synonym/DBLINK Reflection
--------------------------
-
-When using reflection with Table objects, the dialect can optionally search for tables
-indicated by synonyms, either in local or remote schemas or accessed over DBLINK,
-by passing the flag ``oracle_resolve_synonyms=True`` as a
-keyword argument to the :class:`.Table` construct::
-
-    some_table = Table('some_table', autoload=True,
-                                autoload_with=some_engine,
-                                oracle_resolve_synonyms=True)
-
-When this flag is set, the given name (such as ``some_table`` above) will
-be searched not just in the ``ALL_TABLES`` view, but also within the
-``ALL_SYNONYMS`` view to see if this name is actually a synonym to another name.
-If the synonym is located and refers to a DBLINK, the oracle dialect knows
-how to locate the table's information using DBLINK syntax (e.g. ``@dblink``).
-
-``oracle_resolve_synonyms`` is accepted wherever reflection arguments are
-accepted, including methods such as :meth:`.MetaData.reflect` and
-:meth:`.Inspector.get_columns`.
-
-If synonyms are not in use, this flag should be left disabled.
-
-DateTime Compatibility
-----------------------
-
-Oracle has no datatype known as ``DATETIME``, it instead has only ``DATE``,
-which can actually store a date and time value.  For this reason, the Oracle
-dialect provides a type :class:`.oracle.DATE` which is a subclass of
-:class:`.DateTime`.   This type has no special behavior, and is only
-present as a "marker" for this type; additionally, when a database column
-is reflected and the type is reported as ``DATE``, the time-supporting
-:class:`.oracle.DATE` type is used.
-
-.. versionchanged:: 0.9.4 Added :class:`.oracle.DATE` to subclass
-   :class:`.DateTime`.  This is a change as previous versions
-   would reflect a ``DATE`` column as :class:`.types.DATE`, which subclasses
-   :class:`.Date`.   The only significance here is for schemes that are
-   examining the type of column for use in special Python translations or
-   for migrating schemas to other database backends.

-.. dialect:: oracle+cx_oracle
-    :name: cx-Oracle
-    :dbapi: cx_oracle
-    :connectstring: oracle+cx_oracle://user:pass@host:port/dbname[?key=value&key=value...]
-    :url: http://cx-oracle.sourceforge.net/
-
-Additional Connect Arguments
-----------------------------
-
-When connecting with ``dbname`` present, the host, port, and dbname tokens are
-converted to a TNS name using
-the cx_oracle ``makedsn()`` function.  Otherwise, the host token is taken
-directly as a TNS name.
-
-Additional arguments which may be specified either as query string arguments
-on the URL, or as keyword arguments to :func:`.create_engine()` are:
-
-* ``allow_twophase`` - enable two-phase transactions.  Defaults to ``True``.
-
-* ``arraysize`` - set the cx_oracle.arraysize value on cursors, defaulted
-  to 50.  This setting is significant with cx_Oracle as the contents of LOB
-  objects are only readable within a "live" row (e.g. within a batch of
-  50 rows).
-
-* ``auto_convert_lobs`` - defaults to True; See :ref:`cx_oracle_lob`.
-
-* ``auto_setinputsizes`` - the cx_oracle.setinputsizes() call is issued for
-  all bind parameters.  This is required for LOB datatypes but can be
-  disabled to reduce overhead.  Defaults to ``True``.  Specific types
-  can be excluded from this process using the ``exclude_setinputsizes``
-  parameter.
-
-* ``coerce_to_unicode`` - see :ref:`cx_oracle_unicode` for detail.
-
-* ``coerce_to_decimal`` - see :ref:`cx_oracle_numeric` for detail.
-
-* ``exclude_setinputsizes`` - a tuple or list of string DBAPI type names to
-  be excluded from the "auto setinputsizes" feature.  The type names here
-  must match DBAPI types that are found in the "cx_Oracle" module namespace,
-  such as cx_Oracle.UNICODE, cx_Oracle.NCLOB, etc.   Defaults to
-  ``(STRING, UNICODE)``.
-
-  .. versionadded:: 0.8 specific DBAPI types can be excluded from the
-     auto_setinputsizes feature via the exclude_setinputsizes attribute.
-
-* ``mode`` - This is given the string value of SYSDBA or SYSOPER, or alternatively
-  an integer value.  This value is only available as a URL query string
-  argument.
-
-* ``threaded`` - enable multithreaded access to cx_oracle connections.  Defaults
-  to ``True``.  Note that this is the opposite default of the cx_Oracle DBAPI
-  itself.
-
-.. _cx_oracle_unicode:
-
-Unicode
--------
-
-The cx_Oracle DBAPI as of version 5 fully supports unicode, and has the ability
-to return string results as Python unicode objects natively.
-
-When used in Python 3, cx_Oracle returns all strings as Python unicode objects
-(that is, plain ``str`` in Python 3).  In Python 2, it will return as Python
-unicode those column values that are of type ``NVARCHAR`` or ``NCLOB``.  For
-column values that are of type ``VARCHAR`` or other non-unicode string types,
-it will return values as Python strings (e.g. bytestrings).
-
-The cx_Oracle SQLAlchemy dialect presents two different options for the use case of
-returning ``VARCHAR`` column values as Python unicode objects under Python 2:
-
-* the cx_Oracle DBAPI has the ability to coerce all string results to Python
-  unicode objects unconditionally using output type handlers.  This has
-  the advantage that the unicode conversion is global to all statements
-  at the cx_Oracle driver level, meaning it works with raw textual SQL
-  statements that have no typing information associated.  However, this system
-  has been observed to incur signfiicant performance overhead, not only because
-  it takes effect for all string values unconditionally, but also because cx_Oracle under
-  Python 2 seems to use a pure-Python function call in order to do the
-  decode operation, which under cPython can orders of magnitude slower
-  than doing it using C functions alone.
-
-* SQLAlchemy has unicode-decoding services built in, and when using SQLAlchemy's
-  C extensions, these functions do not use any Python function calls and
-  are very fast.  The disadvantage to this approach is that the unicode
-  conversion only takes effect for statements where the :class:`.Unicode` type
-  or :class:`.String` type with ``convert_unicode=True`` is explicitly
-  associated with the result column.  This is the case for any ORM or Core
-  query or SQL expression as well as for a :func:`.text` construct that specifies
-  output column types, so in the vast majority of cases this is not an issue.
-  However, when sending a completely raw string to :meth:`.Connection.execute`,
-  this typing information isn't present, unless the string is handled
-  within a :func:`.text` construct that adds typing information.
-
-As of version 0.9.2 of SQLAlchemy, the default approach is to use SQLAlchemy's
-typing system.  This keeps cx_Oracle's expensive Python 2 approach
-disabled unless the user explicitly wants it.  Under Python 3, SQLAlchemy detects
-that cx_Oracle is returning unicode objects natively and cx_Oracle's system
-is used.
-
-To re-enable cx_Oracle's output type handler under Python 2, the
-``coerce_to_unicode=True`` flag (new in 0.9.4) can be passed to
-:func:`.create_engine`::
-
-    engine = create_engine("oracle+cx_oracle://dsn", coerce_to_unicode=True)
-
-Alternatively, to run a pure string SQL statement and get ``VARCHAR`` results
-as Python unicode under Python 2 without using cx_Oracle's native handlers,
-the :func:`.text` feature can be used::
-
-    from sqlalchemy import text, Unicode
-    result = conn.execute(text("select username from user").columns(username=Unicode))
-
-.. versionchanged:: 0.9.2 cx_Oracle's outputtypehandlers are no longer used for
-   unicode results of non-unicode datatypes in Python 2, after they were identified as a major
-   performance bottleneck.  SQLAlchemy's own unicode facilities are used
-   instead.
-
-.. versionadded:: 0.9.4 Added the ``coerce_to_unicode`` flag, to re-enable
-   cx_Oracle's outputtypehandler and revert to pre-0.9.2 behavior.
-
-.. _cx_oracle_returning:
-
-RETURNING Support
------------------
-
-The cx_oracle DBAPI supports a limited subset of Oracle's already limited RETURNING support.
-Typically, results can only be guaranteed for at most one column being returned;
-this is the typical case when SQLAlchemy uses RETURNING to get just the value of a
-primary-key-associated sequence value.    Additional column expressions will
-cause problems in a non-determinative way, due to cx_oracle's lack of support for
-the OCI_DATA_AT_EXEC API which is required for more complex RETURNING scenarios.
-
-For this reason, stability may be enhanced by disabling RETURNING support completely;
-SQLAlchemy otherwise will use RETURNING to fetch newly sequence-generated
-primary keys.  As illustrated in :ref:`oracle_returning`::
-
-    engine = create_engine("oracle://scott:tiger@dsn", implicit_returning=False)
-
-.. seealso::
-
-    http://docs.oracle.com/cd/B10501_01/appdev.920/a96584/oci05bnd.htm#420693 - OCI documentation for RETURNING
-
-    http://sourceforge.net/mailarchive/message.php?msg_id=31338136 - cx_oracle developer commentary
-
-.. _cx_oracle_lob:
-
-LOB Objects
------------
-
-cx_oracle returns oracle LOBs using the cx_oracle.LOB object.  SQLAlchemy converts
-these to strings so that the interface of the Binary type is consistent with that of
-other backends, and so that the linkage to a live cursor is not needed in scenarios
-like result.fetchmany() and result.fetchall().   This means that by default, LOB
-objects are fully fetched unconditionally by SQLAlchemy, and the linkage to a live
-cursor is broken.
-
-To disable this processing, pass ``auto_convert_lobs=False`` to :func:`.create_engine()`.
-
-Two Phase Transaction Support
------------------------------
-
-Two Phase transactions are implemented using XA transactions, and are known
-to work in a rudimental fashion with recent versions of cx_Oracle
-as of SQLAlchemy 0.8.0b2, 0.7.10.   However, the mechanism is not yet
-considered to be robust and should still be regarded as experimental.
-
-In particular, the cx_Oracle DBAPI as recently as 5.1.2 has a bug regarding
-two phase which prevents
-a particular DBAPI connection from being consistently usable in both
-prepared transactions as well as traditional DBAPI usage patterns; therefore
-once a particular connection is used via :meth:`.Connection.begin_prepared`,
-all subsequent usages of the underlying DBAPI connection must be within
-the context of prepared transactions.
-
-The default behavior of :class:`.Engine` is to maintain a pool of DBAPI
-connections.  Therefore, due to the above glitch, a DBAPI connection that has
-been used in a two-phase operation, and is then returned to the pool, will
-not be usable in a non-two-phase context.   To avoid this situation,
-the application can make one of several choices:
-
-* Disable connection pooling using :class:`.NullPool`
-
-* Ensure that the particular :class:`.Engine` in use is only used
-  for two-phase operations.   A :class:`.Engine` bound to an ORM
-  :class:`.Session` which includes ``twophase=True`` will consistently
-  use the two-phase transaction style.
-
-* For ad-hoc two-phase operations without disabling pooling, the DBAPI
-  connection in use can be evicted from the connection pool using the
-  :meth:`.Connection.detach` method.
-
-.. versionchanged:: 0.8.0b2,0.7.10
-    Support for cx_oracle prepared transactions has been implemented
-    and tested.
-
-.. _cx_oracle_numeric:
-
-Precision Numerics
-------------------
-
-The SQLAlchemy dialect goes through a lot of steps to ensure
-that decimal numbers are sent and received with full accuracy.
-An "outputtypehandler" callable is associated with each
-cx_oracle connection object which detects numeric types and
-receives them as string values, instead of receiving a Python
-``float`` directly, which is then passed to the Python
-``Decimal`` constructor.  The :class:`.Numeric` and
-:class:`.Float` types under the cx_oracle dialect are aware of
-this behavior, and will coerce the ``Decimal`` to ``float`` if
-the ``asdecimal`` flag is ``False`` (default on :class:`.Float`,
-optional on :class:`.Numeric`).
-
-Because the handler coerces to ``Decimal`` in all cases first,
-the feature can detract significantly from performance.
-If precision numerics aren't required, the decimal handling
-can be disabled by passing the flag ``coerce_to_decimal=False``
-to :func:`.create_engine`::
-
-    engine = create_engine("oracle+cx_oracle://dsn", coerce_to_decimal=False)
-
-.. versionadded:: 0.7.6
-    Add the ``coerce_to_decimal`` flag.
-
-Another alternative to performance is to use the
-`cdecimal <http://pypi.python.org/pypi/cdecimal/>`_ library;
-see :class:`.Numeric` for additional notes.
-
-The handler attempts to use the "precision" and "scale"
-attributes of the result set column to best determine if
-subsequent incoming values should be received as ``Decimal`` as
-opposed to int (in which case no processing is added). There are
-several scenarios where OCI_ does not provide unambiguous data
-as to the numeric type, including some situations where
-individual rows may return a combination of floating point and
-integer values. Certain values for "precision" and "scale" have
-been observed to determine this scenario.  When it occurs, the
-outputtypehandler receives as string and then passes off to a
-processing function which detects, for each returned value, if a
-decimal point is present, and if so converts to ``Decimal``,
-otherwise to int.  The intention is that simple int-based
-statements like "SELECT my_seq.nextval() FROM DUAL" continue to
-return ints and not ``Decimal`` objects, and that any kind of
-floating point value is received as a string so that there is no
-floating point loss of precision.
-
-The "decimal point is present" logic itself is also sensitive to
-locale.  Under OCI_, this is controlled by the NLS_LANG
-environment variable. Upon first connection, the dialect runs a
-test to determine the current "decimal" character, which can be
-a comma "," for european locales. From that point forward the
-outputtypehandler uses that character to represent a decimal
-point. Note that cx_oracle 5.0.3 or greater is required
-when dealing with numerics with locale settings that don't use
-a period "." as the decimal character.
-
-.. versionchanged:: 0.6.6
-    The outputtypehandler supports the case where the locale uses a
-    comma "," character to represent a decimal point.

-.. dialect:: postgresql
-    :name: PostgreSQL
-
-
-Sequences/SERIAL
-----------------
-
-PostgreSQL supports sequences, and SQLAlchemy uses these as the default means
-of creating new primary key values for integer-based primary key columns. When
-creating tables, SQLAlchemy will issue the ``SERIAL`` datatype for
-integer-based primary key columns, which generates a sequence and server side
-default corresponding to the column.
-
-To specify a specific named sequence to be used for primary key generation,
-use the :func:`~sqlalchemy.schema.Sequence` construct::
-
-    Table('sometable', metadata,
-            Column('id', Integer, Sequence('some_id_seq'), primary_key=True)
-        )
-
-When SQLAlchemy issues a single INSERT statement, to fulfill the contract of
-having the "last insert identifier" available, a RETURNING clause is added to
-the INSERT statement which specifies the primary key columns should be
-returned after the statement completes. The RETURNING functionality only takes
-place if Postgresql 8.2 or later is in use. As a fallback approach, the
-sequence, whether specified explicitly or implicitly via ``SERIAL``, is
-executed independently beforehand, the returned value to be used in the
-subsequent insert. Note that when an
-:func:`~sqlalchemy.sql.expression.insert()` construct is executed using
-"executemany" semantics, the "last inserted identifier" functionality does not
-apply; no RETURNING clause is emitted nor is the sequence pre-executed in this
-case.
-
-To force the usage of RETURNING by default off, specify the flag
-``implicit_returning=False`` to :func:`.create_engine`.
-
-.. _postgresql_isolation_level:
-
-Transaction Isolation Level
----------------------------
-
-All Postgresql dialects support setting of transaction isolation level
-both via a dialect-specific parameter ``isolation_level``
-accepted by :func:`.create_engine`,
-as well as the ``isolation_level`` argument as passed to :meth:`.Connection.execution_options`.
-When using a non-psycopg2 dialect, this feature works by issuing the
-command ``SET SESSION CHARACTERISTICS AS TRANSACTION ISOLATION LEVEL
-<level>`` for each new connection.
-
-To set isolation level using :func:`.create_engine`::
-
-    engine = create_engine(
-                    "postgresql+pg8000://scott:tiger@localhost/test",
-                    isolation_level="READ UNCOMMITTED"
-                )
-
-To set using per-connection execution options::
-
-    connection = engine.connect()
-    connection = connection.execution_options(isolation_level="READ COMMITTED")
-
-Valid values for ``isolation_level`` include:
-
-* ``READ COMMITTED``
-* ``READ UNCOMMITTED``
-* ``REPEATABLE READ``
-* ``SERIALIZABLE``
-
-The :mod:`~sqlalchemy.dialects.postgresql.psycopg2` dialect also offers the special level ``AUTOCOMMIT``.  See
-:ref:`psycopg2_isolation_level` for details.
-
-.. _postgresql_schema_reflection:
-
-Remote-Schema Table Introspection and Postgresql search_path
-------------------------------------------------------------
-
-The Postgresql dialect can reflect tables from any schema.  The
-:paramref:`.Table.schema` argument, or alternatively the
-:paramref:`.MetaData.reflect.schema` argument determines which schema will
-be searched for the table or tables.   The reflected :class:`.Table` objects
-will in all cases retain this ``.schema`` attribute as was specified.  However,
-with regards to tables which these :class:`.Table` objects refer to via
-foreign key constraint, a decision must be made as to how the ``.schema``
-is represented in those remote tables, in the case where that remote
-schema name is also a member of the current
-`Postgresql search path <http://www.postgresql.org/docs/9.0/static/ddl-schemas.html#DDL-SCHEMAS-PATH>`_.
-
-By default, the Postgresql dialect mimics the behavior encouraged by
-Postgresql's own ``pg_get_constraintdef()`` builtin procedure.  This function
-returns a sample definition for a particular foreign key constraint,
-omitting the referenced schema name from that definition when the name is
-also in the Postgresql schema search path.  The interaction below
-illustrates this behavior::
-
-    test=> CREATE TABLE test_schema.referred(id INTEGER PRIMARY KEY);
-    CREATE TABLE
-    test=> CREATE TABLE referring(
-    test(>         id INTEGER PRIMARY KEY,
-    test(>         referred_id INTEGER REFERENCES test_schema.referred(id));
-    CREATE TABLE
-    test=> SET search_path TO public, test_schema;
-    test=> SELECT pg_catalog.pg_get_constraintdef(r.oid, true) FROM
-    test-> pg_catalog.pg_class c JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
-    test-> JOIN pg_catalog.pg_constraint r  ON c.oid = r.conrelid
-    test-> WHERE c.relname='referring' AND r.contype = 'f'
-    test-> ;
-                   pg_get_constraintdef
-    ---------------------------------------------------
-     FOREIGN KEY (referred_id) REFERENCES referred(id)
-    (1 row)
-
-Above, we created a table ``referred`` as a member of the remote schema ``test_schema``, however
-when we added ``test_schema`` to the PG ``search_path`` and then asked ``pg_get_constraintdef()``
-for the ``FOREIGN KEY`` syntax, ``test_schema`` was not included in the
-output of the function.
-
-On the other hand, if we set the search path back to the typical default
-of ``public``::
-
-    test=> SET search_path TO public;
-    SET
-
-The same query against ``pg_get_constraintdef()`` now returns the fully
-schema-qualified name for us::
-
-    test=> SELECT pg_catalog.pg_get_constraintdef(r.oid, true) FROM
-    test-> pg_catalog.pg_class c JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
-    test-> JOIN pg_catalog.pg_constraint r  ON c.oid = r.conrelid
-    test-> WHERE c.relname='referring' AND r.contype = 'f';
-                         pg_get_constraintdef
-    ---------------------------------------------------------------
-     FOREIGN KEY (referred_id) REFERENCES test_schema.referred(id)
-    (1 row)
-
-SQLAlchemy will by default use the return value of ``pg_get_constraintdef()``
-in order to determine the remote schema name.  That is, if our ``search_path``
-were set to include ``test_schema``, and we invoked a table
-reflection process as follows::
-
-    >>> from sqlalchemy import Table, MetaData, create_engine
-    >>> engine = create_engine("postgresql://scott:tiger@localhost/test")
-    >>> with engine.connect() as conn:
-    ...     conn.execute("SET search_path TO test_schema, public")
-    ...     meta = MetaData()
-    ...     referring = Table('referring', meta, autoload=True, autoload_with=conn)
-    ...
-    <sqlalchemy.engine.result.ResultProxy object at 0x101612ed0>
-
-The above process would deliver to the :attr:`.MetaData.tables` collection
-``referred`` table named **without** the schema::
-
-    >>> meta.tables['referred'].schema is None
-    True
-
-To alter the behavior of reflection such that the referred schema is maintained
-regardless of the ``search_path`` setting, use the ``postgresql_ignore_search_path``
-option, which can be specified as a dialect-specific argument to both
-:class:`.Table` as well as :meth:`.MetaData.reflect`::
-
-    >>> with engine.connect() as conn:
-    ...     conn.execute("SET search_path TO test_schema, public")
-    ...     meta = MetaData()
-    ...     referring = Table('referring', meta, autoload=True, autoload_with=conn,
-    ...                     postgresql_ignore_search_path=True)
-    ...
-    <sqlalchemy.engine.result.ResultProxy object at 0x1016126d0>
-
-We will now have ``test_schema.referred`` stored as schema-qualified::
-
-    >>> meta.tables['test_schema.referred'].schema
-    'test_schema'
-
-.. sidebar:: Best Practices for Postgresql Schema reflection
-
-    The description of Postgresql schema reflection behavior is complex, and is
-    the product of many years of dealing with widely varied use cases and user preferences.
-    But in fact, there's no need to understand any of it if you just stick to the simplest
-    use pattern: leave the ``search_path`` set to its default of ``public`` only, never refer
-    to the name ``public`` as an explicit schema name otherwise, and
-    refer to all other schema names explicitly when building
-    up a :class:`.Table` object.  The options described here are only for those users
-    who can't, or prefer not to, stay within these guidelines.
-
-Note that **in all cases**, the "default" schema is always reflected as ``None``.
-The "default" schema on Postgresql is that which is returned by the
-Postgresql ``current_schema()`` function.  On a typical Postgresql installation,
-this is the name ``public``.  So a table that refers to another which is
-in the ``public`` (i.e. default) schema will always have the ``.schema`` attribute
-set to ``None``.
-
-.. versionadded:: 0.9.2 Added the ``postgresql_ignore_search_path``
-   dialect-level option accepted by :class:`.Table` and :meth:`.MetaData.reflect`.
-
-
-.. seealso::
-
-        `The Schema Search Path <http://www.postgresql.org/docs/9.0/static/ddl-schemas.html#DDL-SCHEMAS-PATH>`_ - on the Postgresql website.
-
-INSERT/UPDATE...RETURNING
--------------------------
-
-The dialect supports PG 8.2's ``INSERT..RETURNING``, ``UPDATE..RETURNING`` and
-``DELETE..RETURNING`` syntaxes.   ``INSERT..RETURNING`` is used by default
-for single-row INSERT statements in order to fetch newly generated
-primary key identifiers.   To specify an explicit ``RETURNING`` clause,
-use the :meth:`._UpdateBase.returning` method on a per-statement basis::
-
-    # INSERT..RETURNING
-    result = table.insert().returning(table.c.col1, table.c.col2).\\
-        values(name='foo')
-    print result.fetchall()
-
-    # UPDATE..RETURNING
-    result = table.update().returning(table.c.col1, table.c.col2).\\
-        where(table.c.name=='foo').values(name='bar')
-    print result.fetchall()
-
-    # DELETE..RETURNING
-    result = table.delete().returning(table.c.col1, table.c.col2).\\
-        where(table.c.name=='foo')
-    print result.fetchall()
-
-.. _postgresql_match:
-
-Full Text Search
-----------------
-
-SQLAlchemy makes available the Postgresql ``@@`` operator via the
-:meth:`.ColumnElement.match` method on any textual column expression.
-On a Postgresql dialect, an expression like the following::
-
-    select([sometable.c.text.match("search string")])
-
-will emit to the database::
-
-    SELECT text @@ to_tsquery('search string') FROM table
-
-The Postgresql text search functions such as ``to_tsquery()``
-and ``to_tsvector()`` are available
-explicitly using the standard :attr:`.func` construct.  For example::
-
-    select([
-        func.to_tsvector('fat cats ate rats').match('cat & rat')
-    ])
-
-Emits the equivalent of::
-
-    SELECT to_tsvector('fat cats ate rats') @@ to_tsquery('cat & rat')
-
-The :class:`.postgresql.TSVECTOR` type can provide for explicit CAST::
-
-    from sqlalchemy.dialects.postgresql import TSVECTOR
-    from sqlalchemy import select, cast
-    select([cast("some text", TSVECTOR)])
-
-produces a statement equivalent to::
-
-    SELECT CAST('some text' AS TSVECTOR) AS anon_1
-
-
-FROM ONLY ...
-------------------------
-
-The dialect supports PostgreSQL's ONLY keyword for targeting only a particular
-table in an inheritance hierarchy. This can be used to produce the
-``SELECT ... FROM ONLY``, ``UPDATE ONLY ...``, and ``DELETE FROM ONLY ...``
-syntaxes. It uses SQLAlchemy's hints mechanism::
-
-    # SELECT ... FROM ONLY ...
-    result = table.select().with_hint(table, 'ONLY', 'postgresql')
-    print result.fetchall()
-
-    # UPDATE ONLY ...
-    table.update(values=dict(foo='bar')).with_hint('ONLY',
-                                                   dialect_name='postgresql')
-
-    # DELETE FROM ONLY ...
-    table.delete().with_hint('ONLY', dialect_name='postgresql')
-
-.. _postgresql_indexes:
-
-Postgresql-Specific Index Options
----------------------------------
-
-Several extensions to the :class:`.Index` construct are available, specific
-to the PostgreSQL dialect.
-
-Partial Indexes
-^^^^^^^^^^^^^^^^
-
-Partial indexes add criterion to the index definition so that the index is
-applied to a subset of rows.   These can be specified on :class:`.Index`
-using the ``postgresql_where`` keyword argument::
-
-  Index('my_index', my_table.c.id, postgresql_where=tbl.c.value > 10)
-
-Operator Classes
-^^^^^^^^^^^^^^^^^
-
-PostgreSQL allows the specification of an *operator class* for each column of
-an index (see
-http://www.postgresql.org/docs/8.3/interactive/indexes-opclass.html).
-The :class:`.Index` construct allows these to be specified via the
-``postgresql_ops`` keyword argument::
-
-    Index('my_index', my_table.c.id, my_table.c.data,
-                            postgresql_ops={
-                                'data': 'text_pattern_ops',
-                                'id': 'int4_ops'
-                            })
-
-.. versionadded:: 0.7.2
-    ``postgresql_ops`` keyword argument to :class:`.Index` construct.
-
-Note that the keys in the ``postgresql_ops`` dictionary are the "key" name of
-the :class:`.Column`, i.e. the name used to access it from the ``.c``
-collection of :class:`.Table`, which can be configured to be different than
-the actual name of the column as expressed in the database.
-
-Index Types
-^^^^^^^^^^^^
-
-PostgreSQL provides several index types: B-Tree, Hash, GiST, and GIN, as well
-as the ability for users to create their own (see
-http://www.postgresql.org/docs/8.3/static/indexes-types.html). These can be
-specified on :class:`.Index` using the ``postgresql_using`` keyword argument::
-
-    Index('my_index', my_table.c.data, postgresql_using='gin')
-
-The value passed to the keyword argument will be simply passed through to the
-underlying CREATE INDEX command, so it *must* be a valid index type for your
-version of PostgreSQL.

-        mytable = Table("mytable", metadata,
-                Column("data", ARRAY(Integer))
-            )
-
-    The above type represents an N-dimensional array,
-    meaning Postgresql will interpret values with any number
-    of dimensions automatically.   To produce an INSERT
-    construct that passes in a 1-dimensional array of integers::
-
-        connection.execute(
-                mytable.insert(),
-                data=[1,2,3]
-        )
-
-    The :class:`.ARRAY` type can be constructed given a fixed number

-
-        mytable = Table("mytable", metadata,
-                Column("data", ARRAY(Integer, dimensions=2))
-            )
-
-    This has the effect of the :class:`.ARRAY` type
-    specifying that number of bracketed blocks when a :class:`.Table`
-    is used in a CREATE TABLE statement, or when the type is used
-    within a :func:`.expression.cast` construct; it also causes
-    the bind parameter and result set processing of the type
-    to optimize itself to expect exactly that number of dimensions.
-    Note that Postgresql itself still allows N dimensions with such a type.
-
-    SQL expressions of type :class:`.ARRAY` have support for "index" and
-    "slice" behavior.  The Python ``[]`` operator works normally here, given
-    integer indexes or slices.  Note that Postgresql arrays default
-    to 1-based indexing.  The operator produces binary expression
-    constructs which will produce the appropriate SQL, both for
-    SELECT statements::
-
-        select([mytable.c.data[5], mytable.c.data[2:7]])
-
-    as well as UPDATE statements when the :meth:`.Update.values` method
-    is used::
-
-        mytable.update().values({
-            mytable.c.data[5]: 7,
-            mytable.c.data[2:7]: [1, 2, 3]
-        })
-
-    :class:`.ARRAY` provides special methods for containment operations,
-    e.g.::
-
-        mytable.c.data.contains([1, 2])
-
-    For a full list of special methods see :class:`.ARRAY.Comparator`.

-
-    * Index operations with a built-in CAST call::

-
-    * Path index operations::

-
-    Index operations return an instance of :class:`.JSONElement`, which represents
-    an expression such as ``column -> index``.  This element then defines
-    methods such as :attr:`.JSONElement.astext` and :meth:`.JSONElement.cast`
-    for setting up type behavior.
-
-    The :class:`.JSON` type, when used with the SQLAlchemy ORM, does not detect
-    in-place mutations to the structure.  In order to detect these, the
-    :mod:`sqlalchemy.ext.mutable` extension must be used.  This extension will
-    allow "in-place" changes to the datastructure to produce events which
-    will be detected by the unit of work.  See the example at :class:`.HSTORE`
-    for a simple example involving a dictionary.
-
-    Custom serializers and deserializers are specified at the dialect level,
-    that is using :func:`.create_engine`.  The reason for this is that when
-    using psycopg2, the DBAPI only allows serializers at the per-cursor
-    or per-connection level.   E.g.::
-
-        engine = create_engine("postgresql://scott:tiger@localhost/test",
-                                json_serializer=my_serialize_fn,
-                                json_deserializer=my_deserialize_fn
-                        )
-
-    When using the psycopg2 dialect, the json_deserializer is registered
-    against the database using ``psycopg2.extras.register_default_json``.

-
-psycopg2 Connect Arguments
------------------------------------
-
-psycopg2-specific keyword arguments which are accepted by
-:func:`.create_engine()` are:
-
-* ``server_side_cursors``: Enable the usage of "server side cursors" for SQL
-  statements which support this feature. What this essentially means from a
-  psycopg2 point of view is that the cursor is created using a name, e.g.
-  ``connection.cursor('some name')``, which has the effect that result rows are
-  not immediately pre-fetched and buffered after statement execution, but are
-  instead left on the server and only retrieved as needed. SQLAlchemy's
-  :class:`~sqlalchemy.engine.ResultProxy` uses special row-buffering
-  behavior when this feature is enabled, such that groups of 100 rows at a
-  time are fetched over the wire to reduce conversational overhead.
-  Note that the ``stream_results=True`` execution option is a more targeted
-  way of enabling this mode on a per-execution basis.
-* ``use_native_unicode``: Enable the usage of Psycopg2 "native unicode" mode
-  per connection.  True by default.
-* ``isolation_level``: This option, available for all Posgtresql dialects,
-  includes the ``AUTOCOMMIT`` isolation level when using the psycopg2
-  dialect.  See :ref:`psycopg2_isolation_level`.
-
-
-Unix Domain Connections
-------------------------
-
-psycopg2 supports connecting via Unix domain connections.   When the ``host``
-portion of the URL is omitted, SQLAlchemy passes ``None`` to psycopg2,
-which specifies Unix-domain communication rather than TCP/IP communication::
-
-    create_engine("postgresql+psycopg2://user:password@/dbname")
-
-By default, the socket file used is to connect to a Unix-domain socket
-in ``/tmp``, or whatever socket directory was specified when PostgreSQL
-was built.  This value can be overridden by passing a pathname to psycopg2,
-using ``host`` as an additional keyword argument::
-
-    create_engine("postgresql+psycopg2://user:password@/dbname?host=/var/lib/postgresql")
-
-See also:
-
-`PQconnectdbParams <http://www.postgresql.org/docs/9.1/static/libpq-connect.html#LIBPQ-PQCONNECTDBPARAMS>`_
-
-Per-Statement/Connection Execution Options
--------------------------------------------
-
-The following DBAPI-specific options are respected when used with
-:meth:`.Connection.execution_options`, :meth:`.Executable.execution_options`,
-:meth:`.Query.execution_options`, in addition to those not specific to DBAPIs:
-
-* isolation_level - Set the transaction isolation level for the lifespan of a
-  :class:`.Connection` (can only be set on a connection, not a statement
-  or query).   See :ref:`psycopg2_isolation_level`.
-
-* stream_results - Enable or disable usage of psycopg2 server side cursors -
-  this feature makes use of "named" cursors in combination with special
-  result handling methods so that result rows are not fully buffered.
-  If ``None`` or not set, the ``server_side_cursors`` option of the
-  :class:`.Engine` is used.
-
-Unicode
--------
-
-By default, the psycopg2 driver uses the ``psycopg2.extensions.UNICODE``
-extension, such that the DBAPI receives and returns all strings as Python
-Unicode objects directly - SQLAlchemy passes these values through without
-change.   Psycopg2 here will encode/decode string values based on the
-current "client encoding" setting; by default this is the value in
-the ``postgresql.conf`` file, which often defaults to ``SQL_ASCII``.
-Typically, this can be changed to ``utf-8``, as a more useful default::
-
-    #client_encoding = sql_ascii # actually, defaults to database
-                                 # encoding
-    client_encoding = utf8
-
-A second way to affect the client encoding is to set it within Psycopg2
-locally.   SQLAlchemy will call psycopg2's ``set_client_encoding()``
-method (see: http://initd.org/psycopg/docs/connection.html#connection.set_client_encoding)
-on all new connections based on the value passed to
-:func:`.create_engine` using the ``client_encoding`` parameter::
-
-    engine = create_engine("postgresql://user:pass@host/dbname", client_encoding='utf8')
-
-This overrides the encoding specified in the Postgresql client configuration.
-
-.. versionadded:: 0.7.3
-    The psycopg2-specific ``client_encoding`` parameter to
-    :func:`.create_engine`.
-
-SQLAlchemy can also be instructed to skip the usage of the psycopg2
-``UNICODE`` extension and to instead utilize it's own unicode encode/decode
-services, which are normally reserved only for those DBAPIs that don't
-fully support unicode directly.  Passing ``use_native_unicode=False`` to
-:func:`.create_engine` will disable usage of ``psycopg2.extensions.UNICODE``.
-SQLAlchemy will instead encode data itself into Python bytestrings on the way
-in and coerce from bytes on the way back,
-using the value of the :func:`.create_engine` ``encoding`` parameter, which
-defaults to ``utf-8``.
-SQLAlchemy's own unicode encode/decode functionality is steadily becoming
-obsolete as more DBAPIs support unicode fully along with the approach of
-Python 3; in modern usage psycopg2 should be relied upon to handle unicode.
-
-Transactions
-------------
-
-The psycopg2 dialect fully supports SAVEPOINT and two-phase commit operations.
-
-.. _psycopg2_isolation_level:
-
-Psycopg2 Transaction Isolation Level
--------------------------------------
-
-As discussed in :ref:`postgresql_isolation_level`,
-all Postgresql dialects support setting of transaction isolation level
-both via the ``isolation_level`` parameter passed to :func:`.create_engine`,
-as well as the ``isolation_level`` argument used by :meth:`.Connection.execution_options`.
-When using the psycopg2 dialect, these options make use of
-psycopg2's ``set_isolation_level()`` connection method, rather than
-emitting a Postgresql directive; this is because psycopg2's API-level
-setting is always emitted at the start of each transaction in any case.
-
-The psycopg2 dialect supports these constants for isolation level:
-
-* ``READ COMMITTED``
-* ``READ UNCOMMITTED``
-* ``REPEATABLE READ``
-* ``SERIALIZABLE``
-* ``AUTOCOMMIT``
-
-.. versionadded:: 0.8.2 support for AUTOCOMMIT isolation level when using
-   psycopg2.
-
-
-NOTICE logging
----------------
-
-The psycopg2 dialect will log Postgresql NOTICE messages via the
-``sqlalchemy.dialects.postgresql`` logger::
-
-    import logging
-    logging.getLogger('sqlalchemy.dialects.postgresql').setLevel(logging.INFO)
-
-.. _psycopg2_hstore::
-
-HSTORE type
-------------
-
-The ``psycopg2`` DBAPI includes an extension to natively handle marshalling of the
-HSTORE type.   The SQLAlchemy psycopg2 dialect will enable this extension
-by default when it is detected that the target database has the HSTORE
-type set up for use.   In other words, when the dialect makes the first
-connection, a sequence like the following is performed:
-
-1. Request the available HSTORE oids using ``psycopg2.extras.HstoreAdapter.get_oids()``.
-   If this function returns a list of HSTORE identifiers, we then determine that
-   the ``HSTORE`` extension is present.
-
-2. If the ``use_native_hstore`` flag is at it's default of ``True``, and
-   we've detected that ``HSTORE`` oids are available, the
-   ``psycopg2.extensions.register_hstore()`` extension is invoked for all
-   connections.
-
-The ``register_hstore()`` extension has the effect of **all Python dictionaries
-being accepted as parameters regardless of the type of target column in SQL**.
-The dictionaries are converted by this extension into a textual HSTORE expression.
-If this behavior is not desired, disable the
-use of the hstore extension by setting ``use_native_hstore`` to ``False`` as follows::
-
-    engine = create_engine("postgresql+psycopg2://scott:tiger@localhost/test",
-                use_native_hstore=False)
-
-The ``HSTORE`` type is **still supported** when the ``psycopg2.extensions.register_hstore()``
-extension is not used.  It merely means that the coercion between Python dictionaries and the HSTORE
-string format, on both the parameter side and the result side, will take
-place within SQLAlchemy's own marshalling logic, and not that of ``psycopg2`` which
-may be more performant.

-.. dialect:: sqlite
-    :name: SQLite
-
-
-Date and Time Types
--------------------
-
-SQLite does not have built-in DATE, TIME, or DATETIME types, and pysqlite does
-not provide out of the box functionality for translating values between Python
-`datetime` objects and a SQLite-supported format. SQLAlchemy's own
-:class:`~sqlalchemy.types.DateTime` and related types provide date formatting
-and parsing functionality when SQlite is used. The implementation classes are
-:class:`~.sqlite.DATETIME`, :class:`~.sqlite.DATE` and :class:`~.sqlite.TIME`.
-These types represent dates and times as ISO formatted strings, which also
-nicely support ordering. There's no reliance on typical "libc" internals for
-these functions so historical dates are fully supported.
-
-Auto Incrementing Behavior
---------------------------
-
-Background on SQLite's autoincrement is at: http://sqlite.org/autoinc.html
-
-Two things to note:
-
-* The AUTOINCREMENT keyword is **not** required for SQLite tables to
-  generate primary key values automatically. AUTOINCREMENT only means that the
-  algorithm used to generate ROWID values should be slightly different.
-* SQLite does **not** generate primary key (i.e. ROWID) values, even for
-  one column, if the table has a composite (i.e. multi-column) primary key.
-  This is regardless of the AUTOINCREMENT keyword being present or not.
-
-To specifically render the AUTOINCREMENT keyword on the primary key column when
-rendering DDL, add the flag ``sqlite_autoincrement=True`` to the Table
-construct::
-
-    Table('sometable', metadata,
-            Column('id', Integer, primary_key=True),
-            sqlite_autoincrement=True)
-
-Transaction Isolation Level
----------------------------
-
-:func:`.create_engine` accepts an ``isolation_level`` parameter which results
-in the command ``PRAGMA read_uncommitted <level>`` being invoked for every new
-connection. Valid values for this parameter are ``SERIALIZABLE`` and ``READ
-UNCOMMITTED`` corresponding to a value of 0 and 1, respectively. See the
-section :ref:`pysqlite_serializable` for an important workaround when using
-serializable isolation with Pysqlite.
-
-Database Locking Behavior / Concurrency
----------------------------------------
-
-Note that SQLite is not designed for a high level of concurrency. The database
-itself, being a file, is locked completely during write operations and within
-transactions, meaning exactly one connection has exclusive access to the
-database during this period - all other connections will be blocked during this
-time.
-
-The Python DBAPI specification also calls for a connection model that is always
-in a transaction; there is no BEGIN method, only commit and rollback. This
-implies that a SQLite DBAPI driver would technically allow only serialized
-access to a particular database file at all times. The pysqlite driver attempts
-to ameliorate this by deferring the actual BEGIN statement until the first DML
-(INSERT, UPDATE, or DELETE) is received within a transaction. While this breaks
-serializable isolation, it at least delays the exclusive locking inherent in
-SQLite's design.
-
-SQLAlchemy's default mode of usage with the ORM is known as "autocommit=False",
-which means the moment the :class:`.Session` begins to be used, a transaction
-is begun. As the :class:`.Session` is used, the autoflush feature, also on by
-default, will flush out pending changes to the database before each query. The
-effect of this is that a :class:`.Session` used in its default mode will often
-emit DML early on, long before the transaction is actually committed. This
-again will have the effect of serializing access to the SQLite database. If
-highly concurrent reads are desired against the SQLite database, it is advised
-that the autoflush feature be disabled, and potentially even that autocommit be
-re-enabled, which has the effect of each SQL statement and flush committing
-changes immediately.
-
-For more information on SQLite's lack of concurrency by design, please see
-`Situations Where Another RDBMS May Work Better - High Concurrency
-<http://www.sqlite.org/whentouse.html>`_ near the bottom of the page.
-
-.. _sqlite_foreign_keys:
-
-Foreign Key Support
--------------------
-
-SQLite supports FOREIGN KEY syntax when emitting CREATE statements for tables,
-however by default these constraints have no effect on the operation of the
-table.
-
-Constraint checking on SQLite has three prerequisites:
-
-* At least version 3.6.19 of SQLite must be in use
-* The SQLite libary must be compiled *without* the SQLITE_OMIT_FOREIGN_KEY
-  or SQLITE_OMIT_TRIGGER symbols enabled.
-* The ``PRAGMA foreign_keys = ON`` statement must be emitted on all connections
-  before use.
-
-SQLAlchemy allows for the ``PRAGMA`` statement to be emitted automatically for
-new connections through the usage of events::
-
-    from sqlalchemy.engine import Engine
-    from sqlalchemy import event
-
-    @event.listens_for(Engine, "connect")
-    def set_sqlite_pragma(dbapi_connection, connection_record):
-        cursor = dbapi_connection.cursor()
-        cursor.execute("PRAGMA foreign_keys=ON")
-        cursor.close()
-
-.. seealso::
-
-    `SQLite Foreign Key Support <http://www.sqlite.org/foreignkeys.html>`_ - on
-    the SQLite web site.
-
-    :ref:`event_toplevel` - SQLAlchemy event API.
-
-.. _sqlite_type_reflection:
-
-Type Reflection
----------------
-
-SQLite types are unlike those of most other database backends, in that
-the string name of the type usually does not correspond to a "type" in a
-one-to-one fashion.  Instead, SQLite links per-column typing behavior
-to one of five so-called "type affinities" based on a string matching
-pattern for the type.
-
-SQLAlchemy's reflection process, when inspecting types, uses a simple
-lookup table to link the keywords returned to provided SQLAlchemy types.
-This lookup table is present within the SQLite dialect as it is for all
-other dialects.  However, the SQLite dialect has a different "fallback"
-routine for when a particular type name is not located in the lookup map;
-it instead implements the SQLite "type affinity" scheme located at
-http://www.sqlite.org/datatype3.html section 2.1.
-
-The provided typemap will make direct associations from an exact string
-name match for the following types:
-
-:class:`~.types.BIGINT`, :class:`~.types.BLOB`,
-:class:`~.types.BOOLEAN`, :class:`~.types.BOOLEAN`,
-:class:`~.types.CHAR`, :class:`~.types.DATE`,
-:class:`~.types.DATETIME`, :class:`~.types.FLOAT`,
-:class:`~.types.DECIMAL`, :class:`~.types.FLOAT`,
-:class:`~.types.INTEGER`, :class:`~.types.INTEGER`,
-:class:`~.types.NUMERIC`, :class:`~.types.REAL`,
-:class:`~.types.SMALLINT`, :class:`~.types.TEXT`,
-:class:`~.types.TIME`, :class:`~.types.TIMESTAMP`,
-:class:`~.types.VARCHAR`, :class:`~.types.NVARCHAR`,
-:class:`~.types.NCHAR`
-
-When a type name does not match one of the above types, the "type affinity"
-lookup is used instead:
-
-* :class:`~.types.INTEGER` is returned if the type name includes the
-  string ``INT``
-* :class:`~.types.TEXT` is returned if the type name includes the
-  string ``CHAR``, ``CLOB`` or ``TEXT``
-* :class:`~.types.NullType` is returned if the type name includes the
-  string ``BLOB``
-* :class:`~.types.REAL` is returned if the type name includes the string
-  ``REAL``, ``FLOA`` or ``DOUB``.
-* Otherwise, the :class:`~.types.NUMERIC` type is used.
-
-.. versionadded:: 0.9.3 Support for SQLite type affinity rules when reflecting
-   columns.

-Driver
-------
-
-When using Python 2.5 and above, the built in ``sqlite3`` driver is
-already installed and no additional installation is needed.  Otherwise,
-the ``pysqlite2`` driver needs to be present.  This is the same driver as
-``sqlite3``, just with a different name.
-
-The ``pysqlite2`` driver will be loaded first, and if not found, ``sqlite3``
-is loaded.  This allows an explicitly installed pysqlite driver to take
-precedence over the built in one.   As with all dialects, a specific
-DBAPI module may be provided to :func:`~sqlalchemy.create_engine()` to control
-this explicitly::
-
-    from sqlite3 import dbapi2 as sqlite
-    e = create_engine('sqlite+pysqlite:///file.db', module=sqlite)
-
-
-Connect Strings
----------------
-
-The file specification for the SQLite database is taken as the "database"
-portion of the URL.  Note that the format of a SQLAlchemy url is::
-
-    driver://user:pass@host/database
-
-This means that the actual filename to be used starts with the characters to
-the **right** of the third slash.   So connecting to a relative filepath
-looks like::
-
-    # relative path
-    e = create_engine('sqlite:///path/to/database.db')
-
-An absolute path, which is denoted by starting with a slash, means you
-need **four** slashes::
-
-    # absolute path
-    e = create_engine('sqlite:////path/to/database.db')
-
-To use a Windows path, regular drive specifications and backslashes can be
-used. Double backslashes are probably needed::
-
-    # absolute path on Windows
-    e = create_engine('sqlite:///C:\\\\path\\\\to\\\\database.db')
-
-The sqlite ``:memory:`` identifier is the default if no filepath is
-present.  Specify ``sqlite://`` and nothing else::
-
-    # in-memory database
-    e = create_engine('sqlite://')
-
-Compatibility with sqlite3 "native" date and datetime types
------------------------------------------------------------
-
-The pysqlite driver includes the sqlite3.PARSE_DECLTYPES and
-sqlite3.PARSE_COLNAMES options, which have the effect of any column
-or expression explicitly cast as "date" or "timestamp" will be converted
-to a Python date or datetime object.  The date and datetime types provided
-with the pysqlite dialect are not currently compatible with these options,
-since they render the ISO date/datetime including microseconds, which
-pysqlite's driver does not.   Additionally, SQLAlchemy does not at
-this time automatically render the "cast" syntax required for the
-freestanding functions "current_timestamp" and "current_date" to return
-datetime/date types natively.   Unfortunately, pysqlite
-does not provide the standard DBAPI types in ``cursor.description``,
-leaving SQLAlchemy with no way to detect these types on the fly
-without expensive per-row type checks.
-
-Keeping in mind that pysqlite's parsing option is not recommended,
-nor should be necessary, for use with SQLAlchemy, usage of PARSE_DECLTYPES
-can be forced if one configures "native_datetime=True" on create_engine()::
-
-    engine = create_engine('sqlite://',
-        connect_args={'detect_types': sqlite3.PARSE_DECLTYPES|sqlite3.PARSE_COLNAMES},
-        native_datetime=True
-    )
-
-With this flag enabled, the DATE and TIMESTAMP types (but note - not the
-DATETIME or TIME types...confused yet ?) will not perform any bind parameter
-or result processing. Execution of "func.current_date()" will return a string.
-"func.current_timestamp()" is registered as returning a DATETIME type in
-SQLAlchemy, so this function still receives SQLAlchemy-level result processing.
-
-.. _pysqlite_threading_pooling:
-
-Threading/Pooling Behavior
----------------------------
-
-Pysqlite's default behavior is to prohibit the usage of a single connection
-in more than one thread.   This is originally intended to work with older
-versions of SQLite that did not support multithreaded operation under
-various circumstances.  In particular, older SQLite versions
-did not allow a ``:memory:`` database to be used in multiple threads
-under any circumstances.
-
-Pysqlite does include a now-undocumented flag known as
-``check_same_thread`` which will disable this check, however note that pysqlite
-connections are still not safe to use in concurrently in multiple threads.
-In particular, any statement execution calls would need to be externally
-mutexed, as Pysqlite does not provide for thread-safe propagation of error
-messages among other things.   So while even ``:memory:`` databases can be
-shared among threads in modern SQLite, Pysqlite doesn't provide enough
-thread-safety to make this usage worth it.
-
-SQLAlchemy sets up pooling to work with Pysqlite's default behavior:
-
-* When a ``:memory:`` SQLite database is specified, the dialect by default
-  will use :class:`.SingletonThreadPool`. This pool maintains a single
-  connection per thread, so that all access to the engine within the current
-  thread use the same ``:memory:`` database - other threads would access a
-  different ``:memory:`` database.
-* When a file-based database is specified, the dialect will use
-  :class:`.NullPool` as the source of connections. This pool closes and
-  discards connections which are returned to the pool immediately. SQLite
-  file-based connections have extremely low overhead, so pooling is not
-  necessary. The scheme also prevents a connection from being used again in
-  a different thread and works best with SQLite's coarse-grained file locking.
-
-  .. versionchanged:: 0.7
-      Default selection of :class:`.NullPool` for SQLite file-based databases.
-      Previous versions select :class:`.SingletonThreadPool` by
-      default for all SQLite databases.
-
-
-Using a Memory Database in Multiple Threads
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-To use a ``:memory:`` database in a multithreaded scenario, the same connection
-object must be shared among threads, since the database exists
-only within the scope of that connection.   The
-:class:`.StaticPool` implementation will maintain a single connection
-globally, and the ``check_same_thread`` flag can be passed to Pysqlite
-as ``False``::
-
-    from sqlalchemy.pool import StaticPool
-    engine = create_engine('sqlite://',
-                        connect_args={'check_same_thread':False},
-                        poolclass=StaticPool)
-
-Note that using a ``:memory:`` database in multiple threads requires a recent
-version of SQLite.
-
-Using Temporary Tables with SQLite
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Due to the way SQLite deals with temporary tables, if you wish to use a
-temporary table in a file-based SQLite database across multiple checkouts
-from the connection pool, such as when using an ORM :class:`.Session` where
-the temporary table should continue to remain after :meth:`.Session.commit` or
-:meth:`.Session.rollback` is called, a pool which maintains a single connection must
-be used.   Use :class:`.SingletonThreadPool` if the scope is only needed
-within the current thread, or :class:`.StaticPool` is scope is needed within
-multiple threads for this case::
-
-    # maintain the same connection per thread
-    from sqlalchemy.pool import SingletonThreadPool
-    engine = create_engine('sqlite:///mydb.db',
-                        poolclass=SingletonThreadPool)
-
-
-    # maintain the same connection across all threads
-    from sqlalchemy.pool import StaticPool
-    engine = create_engine('sqlite:///mydb.db',
-                        poolclass=StaticPool)
-
-Note that :class:`.SingletonThreadPool` should be configured for the number
-of threads that are to be used; beyond that number, connections will be
-closed out in a non deterministic way.
-
-Unicode
--------
-
-The pysqlite driver only returns Python ``unicode`` objects in result sets,
-never plain strings, and accommodates ``unicode`` objects within bound
-parameter values in all cases.   Regardless of the SQLAlchemy string type in
-use, string-based result values will by Python ``unicode`` in Python 2.
-The :class:`.Unicode` type should still be used to indicate those columns that
-require unicode, however, so that non-``unicode`` values passed inadvertently
-will emit a warning.  Pysqlite will emit an error if a non-``unicode`` string
-is passed containing non-ASCII characters.
-
-.. _pysqlite_serializable:
-
-Serializable Transaction Isolation
-----------------------------------
-
-The pysqlite DBAPI driver has a long-standing bug in which transactional
-state is not begun until the first DML statement, that is INSERT, UPDATE
-or DELETE, is emitted.  A SELECT statement will not cause transactional
-state to begin.   While this mode of usage is fine for typical situations
-and has the advantage that the SQLite database file is not prematurely
-locked, it breaks serializable transaction isolation, which requires
-that the database file be locked upon any SQL being emitted.
-
-To work around this issue, the ``BEGIN`` keyword can be emitted
-at the start of each transaction.   The following recipe establishes
-a :meth:`.ConnectionEvents.begin` handler to achieve this::
-
-    from sqlalchemy import create_engine, event
-
-    engine = create_engine("sqlite:///myfile.db", isolation_level='SERIALIZABLE')
-
-    @event.listens_for(engine, "begin")
-    def do_begin(conn):
-        conn.execute("BEGIN")

-"""SQL connections, SQL execution and high-level DB-API interface.
-
-The engine package defines the basic components used to interface
-DB-API modules with higher-level statement construction,
-connection-management, execution and result contexts.  The primary
-"entry point" class into this package is the Engine and it's public
-constructor ``create_engine()``.
-
-This package includes:
-
-base.py
-    Defines interface classes and some implementation classes which
-    comprise the basic components used to interface between a DB-API,
-    constructed and plain-text statements, connections, transactions,
-    and results.
-
-default.py
-    Contains default implementations of some of the components defined
-    in base.py.  All current database dialects use the classes in
-    default.py as base classes for their own database-specific
-    implementations.
-
-strategies.py
-    The mechanics of constructing ``Engine`` objects are represented
-    here.  Defines the ``EngineStrategy`` class which represents how
-    to go from arguments specified to the ``create_engine()``
-    function, to a fully constructed ``Engine``, including
-    initialization of connection pooling, dialects, and specific
-    subclasses of ``Engine``.
-
-threadlocal.py
-    The ``TLEngine`` class is defined here, which is a subclass of
-    the generic ``Engine`` and tracks ``Connection`` and
-    ``Transaction`` objects against the identity of the current
-    thread.  This allows certain programming patterns based around
-    the concept of a "thread-local connection" to be possible.

-def create_engine(*args, **kwargs):
-    """Create a new :class:`.Engine` instance.
-
-    The standard calling form is to send the URL as the
-    first positional argument, usually a string
-    that indicates database dialect and connection arguments::
-
-
-        engine = create_engine("postgresql://scott:tiger@localhost/test")
-
-    Additional keyword arguments may then follow it which
-    establish various options on the resulting :class:`.Engine`
-    and its underlying :class:`.Dialect` and :class:`.Pool`
-    constructs::
-
-        engine = create_engine("mysql://scott:tiger@hostname/dbname",
-                                    encoding='latin1', echo=True)
-
-    The string form of the URL is
-    ``dialect[+driver]://user:password@host/dbname[?key=value..]``, where
-    ``dialect`` is a database name such as ``mysql``, ``oracle``,
-    ``postgresql``, etc., and ``driver`` the name of a DBAPI, such as
-    ``psycopg2``, ``pyodbc``, ``cx_oracle``, etc.  Alternatively,
-    the URL can be an instance of :class:`~sqlalchemy.engine.url.URL`.
-
-    ``**kwargs`` takes a wide variety of options which are routed
-    towards their appropriate components.  Arguments may be specific to
-    the :class:`.Engine`, the underlying :class:`.Dialect`, as well as the
-    :class:`.Pool`.  Specific dialects also accept keyword arguments that
-    are unique to that dialect.   Here, we describe the parameters
-    that are common to most :func:`.create_engine()` usage.
-
-    Once established, the newly resulting :class:`.Engine` will
-    request a connection from the underlying :class:`.Pool` once
-    :meth:`.Engine.connect` is called, or a method which depends on it
-    such as :meth:`.Engine.execute` is invoked.   The :class:`.Pool` in turn
-    will establish the first actual DBAPI connection when this request
-    is received.   The :func:`.create_engine` call itself does **not**
-    establish any actual DBAPI connections directly.
-
-    .. seealso::
-
-        :doc:`/core/engines`
-
-        :doc:`/dialects/index`
-
-        :ref:`connections_toplevel`
-
-    :param case_sensitive=True: if False, result column names
-       will match in a case-insensitive fashion, that is,
-       ``row['SomeColumn']``.
-
-       .. versionchanged:: 0.8
-           By default, result row names match case-sensitively.
-           In version 0.7 and prior, all matches were case-insensitive.
-
-    :param connect_args: a dictionary of options which will be
-        passed directly to the DBAPI's ``connect()`` method as
-        additional keyword arguments.  See the example
-        at :ref:`custom_dbapi_args`.
-
-    :param convert_unicode=False: if set to True, sets
-        the default behavior of ``convert_unicode`` on the
-        :class:`.String` type to ``True``, regardless
-        of a setting of ``False`` on an individual
-        :class:`.String` type, thus causing all :class:`.String`
-        -based columns
-        to accommodate Python ``unicode`` objects.  This flag
-        is useful as an engine-wide setting when using a
-        DBAPI that does not natively support Python
-        ``unicode`` objects and raises an error when
-        one is received (such as pyodbc with FreeTDS).
-
-        See :class:`.String` for further details on
-        what this flag indicates.
-
-    :param creator: a callable which returns a DBAPI connection.
-        This creation function will be passed to the underlying
-        connection pool and will be used to create all new database
-        connections. Usage of this function causes connection
-        parameters specified in the URL argument to be bypassed.
-
-    :param echo=False: if True, the Engine will log all statements
-        as well as a repr() of their parameter lists to the engines
-        logger, which defaults to sys.stdout. The ``echo`` attribute of
-        ``Engine`` can be modified at any time to turn logging on and
-        off. If set to the string ``"debug"``, result rows will be
-        printed to the standard output as well. This flag ultimately
-        controls a Python logger; see :ref:`dbengine_logging` for
-        information on how to configure logging directly.
-
-    :param echo_pool=False: if True, the connection pool will log
-        all checkouts/checkins to the logging stream, which defaults to
-        sys.stdout. This flag ultimately controls a Python logger; see
-        :ref:`dbengine_logging` for information on how to configure logging
-        directly.
-
-    :param encoding: Defaults to ``utf-8``.  This is the string
-        encoding used by SQLAlchemy for string encode/decode
-        operations which occur within SQLAlchemy, **outside of
-        the DBAPI.**  Most modern DBAPIs feature some degree of
-        direct support for Python ``unicode`` objects,
-        what you see in Python 2 as a string of the form
-        ``u'some string'``.  For those scenarios where the
-        DBAPI is detected as not supporting a Python ``unicode``
-        object, this encoding is used to determine the
-        source/destination encoding.  It is **not used**
-        for those cases where the DBAPI handles unicode
-        directly.
-
-        To properly configure a system to accommodate Python
-        ``unicode`` objects, the DBAPI should be
-        configured to handle unicode to the greatest
-        degree as is appropriate - see
-        the notes on unicode pertaining to the specific
-        target database in use at :ref:`dialect_toplevel`.
-
-        Areas where string encoding may need to be accommodated
-        outside of the DBAPI include zero or more of:
-
-        * the values passed to bound parameters, corresponding to
-          the :class:`.Unicode` type or the :class:`.String` type
-          when ``convert_unicode`` is ``True``;
-        * the values returned in result set columns corresponding
-          to the :class:`.Unicode` type or the :class:`.String`
-          type when ``convert_unicode`` is ``True``;
-        * the string SQL statement passed to the DBAPI's
-          ``cursor.execute()`` method;
-        * the string names of the keys in the bound parameter
-          dictionary passed to the DBAPI's ``cursor.execute()``
-          as well as ``cursor.setinputsizes()`` methods;
-        * the string column names retrieved from the DBAPI's
-          ``cursor.description`` attribute.
-
-        When using Python 3, the DBAPI is required to support
-        *all* of the above values as Python ``unicode`` objects,
-        which in Python 3 are just known as ``str``.  In Python 2,
-        the DBAPI does not specify unicode behavior at all,
-        so SQLAlchemy must make decisions for each of the above
-        values on a per-DBAPI basis - implementations are
-        completely inconsistent in their behavior.
-
-    :param execution_options: Dictionary execution options which will
-        be applied to all connections.  See
-        :meth:`~sqlalchemy.engine.Connection.execution_options`
-
-    :param implicit_returning=True: When ``True``, a RETURNING-
-        compatible construct, if available, will be used to
-        fetch newly generated primary key values when a single row
-        INSERT statement is emitted with no existing returning()
-        clause.  This applies to those backends which support RETURNING
-        or a compatible construct, including Postgresql, Firebird, Oracle,
-        Microsoft SQL Server.   Set this to ``False`` to disable
-        the automatic usage of RETURNING.
-
-    :param label_length=None: optional integer value which limits
-        the size of dynamically generated column labels to that many
-        characters. If less than 6, labels are generated as
-        "_(counter)". If ``None``, the value of
-        ``dialect.max_identifier_length`` is used instead.
-
-    :param listeners: A list of one or more
-        :class:`~sqlalchemy.interfaces.PoolListener` objects which will
-        receive connection pool events.
-
-    :param logging_name:  String identifier which will be used within
-        the "name" field of logging records generated within the
-        "sqlalchemy.engine" logger. Defaults to a hexstring of the
-        object's id.
-
-    :param max_overflow=10: the number of connections to allow in
-        connection pool "overflow", that is connections that can be
-        opened above and beyond the pool_size setting, which defaults
-        to five. this is only used with :class:`~sqlalchemy.pool.QueuePool`.
-
-    :param module=None: reference to a Python module object (the module
-        itself, not its string name).  Specifies an alternate DBAPI module to
-        be used by the engine's dialect.  Each sub-dialect references a
-        specific DBAPI which will be imported before first connect.  This
-        parameter causes the import to be bypassed, and the given module to
-        be used instead. Can be used for testing of DBAPIs as well as to
-        inject "mock" DBAPI implementations into the :class:`.Engine`.
-
-    :param pool=None: an already-constructed instance of
-        :class:`~sqlalchemy.pool.Pool`, such as a
-        :class:`~sqlalchemy.pool.QueuePool` instance. If non-None, this
-        pool will be used directly as the underlying connection pool
-        for the engine, bypassing whatever connection parameters are
-        present in the URL argument. For information on constructing
-        connection pools manually, see :ref:`pooling_toplevel`.
-
-    :param poolclass=None: a :class:`~sqlalchemy.pool.Pool`
-        subclass, which will be used to create a connection pool
-        instance using the connection parameters given in the URL. Note
-        this differs from ``pool`` in that you don't actually
-        instantiate the pool in this case, you just indicate what type
-        of pool to be used.
-
-    :param pool_logging_name:  String identifier which will be used within
-       the "name" field of logging records generated within the
-       "sqlalchemy.pool" logger. Defaults to a hexstring of the object's
-       id.
-
-    :param pool_size=5: the number of connections to keep open
-        inside the connection pool. This used with
-        :class:`~sqlalchemy.pool.QueuePool` as
-        well as :class:`~sqlalchemy.pool.SingletonThreadPool`.  With
-        :class:`~sqlalchemy.pool.QueuePool`, a ``pool_size`` setting
-        of 0 indicates no limit; to disable pooling, set ``poolclass`` to
-        :class:`~sqlalchemy.pool.NullPool` instead.
-
-    :param pool_recycle=-1: this setting causes the pool to recycle
-        connections after the given number of seconds has passed. It
-        defaults to -1, or no timeout. For example, setting to 3600
-        means connections will be recycled after one hour. Note that
-        MySQL in particular will disconnect automatically if no
-        activity is detected on a connection for eight hours (although
-        this is configurable with the MySQLDB connection itself and the
-        server configuration as well).
-
-    :param pool_reset_on_return='rollback': set the "reset on return"
-        behavior of the pool, which is whether ``rollback()``,
-        ``commit()``, or nothing is called upon connections
-        being returned to the pool.  See the docstring for
-        ``reset_on_return`` at :class:`.Pool`.
-
-        .. versionadded:: 0.7.6
-
-    :param pool_timeout=30: number of seconds to wait before giving
-        up on getting a connection from the pool. This is only used
-        with :class:`~sqlalchemy.pool.QueuePool`.
-
-    :param strategy='plain': selects alternate engine implementations.
-        Currently available are:
-
-        * the ``threadlocal`` strategy, which is described in
-          :ref:`threadlocal_strategy`;
-        * the ``mock`` strategy, which dispatches all statement
-          execution to a function passed as the argument ``executor``.
-          See `example in the FAQ
-          <http://www.sqlalchemy.org/trac/wiki/FAQ#HowcanIgettheCREATETABLEDROPTABLEoutputasastring>`_.
-
-    :param executor=None: a function taking arguments

-          setting is not removed until the underlying DBAPI connection

-          Some DBAPIs such as psycopg2 and mysql-python consider
-          percent signs as significant only when parameters are
-          present; this option allows code to generate SQL
-          containing percent signs (and possibly other characters)

-        ``shard_id=shard1``, and ``shard2`` will produce :class:`.Connection`
-        objects that contain the execution option ``shard_id=shard2``.
-
-        An event handler can consume the above execution option to perform
-        a schema switch or other operation, given a connection.  Below
-        we emit a MySQL ``use`` statement to switch databases, at the same
-        time keeping track of which database we've established using the

-
-    Any aspect of metadata definition, SQL query generation,
-    execution, result-set handling, or anything else which varies
-    between databases is defined under the general category of the
-    Dialect.  The Dialect acts as a factory for other
-    database-specific object implementations including
-    ExecutionContext, Compiled, DefaultGenerator, and TypeEngine.
-
-    All Dialects implement the following attributes:
-
-    name
-      identifying name for the dialect from a DBAPI-neutral point of view
-      (i.e. 'sqlite')
-
-    driver
-      identifying name for the dialect's DBAPI
-
-    positional
-      True if the paramstyle for this Dialect is positional.
-
-    paramstyle
-      the paramstyle to be used (some DB-APIs support multiple
-      paramstyles).
-
-    convert_unicode
-      True if Unicode conversion should be applied to all ``str``
-      types.
-
-    encoding
-      type of encoding to use for unicode, usually defaults to
-      'utf-8'.

-      a :class:`.Compiled` class used to compile SQL statements
-
-    ddl_compiler
-      a :class:`.Compiled` class used to compile DDL statements
-
-    server_version_info
-      a tuple containing a version number for the DB backend in use.
-      This value is only available for supporting dialects, and is
-      typically populated during the initial connection to the database.
-
-    default_schema_name
-     the name of the default schema.  This value is only available for
-     supporting dialects, and is typically populated during the
-     initial connection to the database.
-
-    execution_ctx_cls
-      a :class:`.ExecutionContext` class used to handle statement execution
-
-    execute_sequence_format
-      either the 'tuple' or 'list' type, depending on what cursor.execute()
-      accepts for the second argument (they vary).
-
-    preparer
-      a :class:`~sqlalchemy.sql.compiler.IdentifierPreparer` class used to
-      quote identifiers.
-
-    supports_alter
-      ``True`` if the database supports ``ALTER TABLE``.
-
-    max_identifier_length
-      The maximum length of identifier names.
-
-    supports_unicode_statements
-      Indicate whether the DB-API can receive SQL statements as Python
-      unicode strings
-
-    supports_unicode_binds
-      Indicate whether the DB-API can receive string bind parameters
-      as Python unicode strings

-    supports_sane_rowcount
-      Indicate whether the dialect properly implements rowcount for
-      ``UPDATE`` and ``DELETE`` statements.
-
-    supports_sane_multi_rowcount
-      Indicate whether the dialect properly implements rowcount for
-      ``UPDATE`` and ``DELETE`` statements when executed via
-      executemany.
-
-    preexecute_autoincrement_sequences
-      True if 'implicit' primary key functions must be executed separately
-      in order to get their value.   This is currently oriented towards

-      which are then available via inserted_primary_key.
-      If an insert statement has returning() specified explicitly,
-      the "implicit" functionality is not used and inserted_primary_key
-      will not be available.
-
-    dbapi_type_map
-      A mapping of DB-API type objects present in this Dialect's
-      DB-API implementation mapped to TypeEngine implementations used
-      by the dialect.
-
-      This is used to apply types to result sets based on the DB-API
-      types present in cursor.description; it only takes effect for
-      result sets against textual statements where no explicit
-      typemap was present.
-
-    colspecs
-      A dictionary of TypeEngine classes from sqlalchemy.types mapped
-      to subclasses that are specific to the dialect class.  This
-      dictionary is class-level only and is not accessed from the
-      dialect instance itself.
-
-    supports_default_values
-      Indicates if the construct ``INSERT INTO tablename DEFAULT
-      VALUES`` is supported
-
-    supports_sequences
-      Indicates if the dialect supports CREATE SEQUENCE or similar.
-
-    sequences_optional
-      If True, indicates if the "optional" flag on the Sequence() construct
-      should signal to not generate a CREATE SEQUENCE. Applies only to
-      dialects that support sequences. Currently used only to allow Postgresql
-      SERIAL to be used on a column that specifies Sequence() for usage on
-      other backends.
-
-    supports_native_enum
-      Indicates if the dialect supports a native ENUM construct.
-      This will prevent types.Enum from generating a CHECK
-      constraint when that type is used.
-
-    supports_native_boolean
-      Indicates if the dialect supports a native boolean construct.
-      This will prevent types.Boolean from generating a CHECK
-      constraint when that type is used.

-"""Provides an abstraction for obtaining database schema information.
-
-Usage Notes:
-
-Here are some general conventions when accessing the low level inspector
-methods such as get_table_names, get_columns, etc.
-
-1. Inspector methods return lists of dicts in most cases for the following
-   reasons:
-
-   * They're both standard types that can be serialized.
-   * Using a dict instead of a tuple allows easy expansion of attributes.
-   * Using a list for the outer structure maintains order and is easy to work
-     with (e.g. list comprehension [d['name'] for d in cols]).
-
-2. Records that contain a name, such as the column name in a column record
-   use the key 'name'. So for most return values, each record will have a
-   'name' attribute..

-"""Attribute implementation for _Dispatch classes.
-
-The various listener targets for a particular event class are represented
-as attributes, which refer to collections of listeners to be fired off.
-These collections can exist at the class level as well as at the instance
-level.  An event is fired off using code like this::
-
-    some_object.dispatch.first_connect(arg1, arg2)
-
-Above, ``some_object.dispatch`` would be an instance of ``_Dispatch`` and
-``first_connect`` is typically an instance of ``_ListenerCollection``
-if event listeners are present, or ``_EmptyListener`` if none are present.
-
-The attribute mechanics here spend effort trying to ensure listener functions
-are available with a minimum of function call overhead, that unnecessary
-objects aren't created (i.e. many empty per-instance listener collections),
-as well as that everything is garbage collectable when owning references are
-lost.  Other features such as "propagation" of listener functions across
-many ``_Dispatch`` instances, "joining" of multiple ``_Dispatch`` instances,
-as well as support for subclass propagation (e.g. events assigned to
-``Pool`` vs. ``QueuePool``) are all implemented here.

-    """Return a Python property implementing a view of a target
-    attribute which references an attribute on members of the
-    target.
-
-    The returned value is an instance of :class:`.AssociationProxy`.
-
-    Implements a Python property representing a relationship as a collection
-    of simpler values, or a scalar value.  The proxied property will mimic
-    the collection type of the target (list, dict or set), or, in the case of
-    a one to one relationship, a simple scalar value.
-
-    :param target_collection: Name of the attribute we'll proxy to.
-      This attribute is typically mapped by
-      :func:`~sqlalchemy.orm.relationship` to link to a target collection, but
-      can also be a many-to-one or non-scalar relationship.
-
-    :param attr: Attribute on the associated instance or instances we'll
-      proxy for.
-
-      For example, given a target collection of [obj1, obj2], a list created
-      by this proxy property would look like [getattr(obj1, *attr*),
-      getattr(obj2, *attr*)]
-
-      If the relationship is one-to-one or otherwise uselist=False, then
-      simply: getattr(obj, *attr*)
-
-    :param creator: optional.
-
-      When new items are added to this proxied collection, new instances of
-      the class collected by the target collection will be created.  For list
-      and set collections, the target class constructor will be called with
-      the 'value' for the new instance.  For dict types, two arguments are
-      passed: key and value.
-
-      If you want to construct instances differently, supply a *creator*
-      function that takes arguments as above and returns instances.
-
-      For scalar relationships, creator() will be called if the target is None.
-      If the target is present, set operations are proxied to setattr() on the
-      associated object.
-
-      If you have an associated object with multiple attributes, you may set
-      up multiple association proxies mapping to different attributes.  See
-      the unit tests for examples, and for examples of how creator() functions
-      can be used to construct the scalar relationship on-demand in this
-      situation.
-
-    :param \*\*kw: Passes along any other keyword arguments to
-      :class:`.AssociationProxy`.

-"""Define an extension to the :mod:`sqlalchemy.ext.declarative` system
-which automatically generates mapped classes and relationships from a database
-schema, typically though not necessarily one which is reflected.
-
-.. versionadded:: 0.9.1 Added :mod:`sqlalchemy.ext.automap`.
-
-.. note::
-
-    The :mod:`sqlalchemy.ext.automap` extension should be considered
-    **experimental** as of 0.9.1.   Featureset and API stability is
-    not guaranteed at this time.
-
-It is hoped that the :class:`.AutomapBase` system provides a quick
-and modernized solution to the problem that the very famous
-`SQLSoup <https://sqlsoup.readthedocs.org/en/latest/>`_
-also tries to solve, that of generating a quick and rudimentary object
-model from an existing database on the fly.  By addressing the issue strictly
-at the mapper configuration level, and integrating fully with existing
-Declarative class techniques, :class:`.AutomapBase` seeks to provide
-a well-integrated approach to the issue of expediently auto-generating ad-hoc
-mappings.
-
-
-Basic Use
-=========
-
-The simplest usage is to reflect an existing database into a new model.
-We create a new :class:`.AutomapBase` class in a similar manner as to how
-we create a declarative base class, using :func:`.automap_base`.
-We then call :meth:`.AutomapBase.prepare` on the resulting base class,
-asking it to reflect the schema and produce mappings::
-
-    from sqlalchemy.ext.automap import automap_base
-    from sqlalchemy.orm import Session
-    from sqlalchemy import create_engine
-
-    Base = automap_base()
-
-    # engine, suppose it has two tables 'user' and 'address' set up
-    engine = create_engine("sqlite:///mydatabase.db")
-
-    # reflect the tables
-    Base.prepare(engine, reflect=True)
-
-    # mapped classes are now created with names by default
-    # matching that of the table name.
-    User = Base.classes.user
-    Address = Base.classes.address
-
-    session = Session(engine)
-
-    # rudimentary relationships are produced
-    session.add(Address(email_address="foo@bar.com", user=User(name="foo")))
-    session.commit()
-
-    # collection-based relationships are by default named "<classname>_collection"
-    print (u1.address_collection)
-
-Above, calling :meth:`.AutomapBase.prepare` while passing along the
-:paramref:`.AutomapBase.prepare.reflect` parameter indicates that the
-:meth:`.MetaData.reflect` method will be called on this declarative base
-classes' :class:`.MetaData` collection; then, each viable
-:class:`.Table` within the :class:`.MetaData` will get a new mapped class
-generated automatically.  The :class:`.ForeignKeyConstraint` objects which
-link the various tables together will be used to produce new, bidirectional
-:func:`.relationship` objects between classes.   The classes and relationships
-follow along a default naming scheme that we can customize.  At this point,
-our basic mapping consisting of related ``User`` and ``Address`` classes is ready
-to use in the traditional way.
-
-Generating Mappings from an Existing MetaData
-=============================================
-
-We can pass a pre-declared :class:`.MetaData` object to :func:`.automap_base`.
-This object can be constructed in any way, including programmatically, from
-a serialized file, or from itself being reflected using :meth:`.MetaData.reflect`.
-Below we illustrate a combination of reflection and explicit table declaration::
-
-    from sqlalchemy import create_engine, MetaData, Table, Column, ForeignKey
-    engine = create_engine("sqlite:///mydatabase.db")
-
-    # produce our own MetaData object
-    metadata = MetaData()
-
-    # we can reflect it ourselves from a database, using options
-    # such as 'only' to limit what tables we look at...
-    metadata.reflect(engine, only=['user', 'address'])
-
-    # ... or just define our own Table objects with it (or combine both)
-    Table('user_order', metadata,
-                    Column('id', Integer, primary_key=True),
-                    Column('user_id', ForeignKey('user.id'))
-                )
-
-    # we can then produce a set of mappings from this MetaData.
-    Base = automap_base(metadata=metadata)
-
-    # calling prepare() just sets up mapped classes and relationships.
-    Base.prepare()
-
-    # mapped classes are ready
-    User, Address, Order = Base.classes.user, Base.classes.address, Base.classes.user_order
-
-Specifying Classes Explcitly
-============================
-
-The :mod:`.sqlalchemy.ext.automap` extension allows classes to be defined
-explicitly, in a way similar to that of the :class:`.DeferredReflection` class.
-Classes that extend from :class:`.AutomapBase` act like regular declarative
-classes, but are not immediately mapped after their construction, and are instead
-mapped when we call :meth:`.AutomapBase.prepare`.  The :meth:`.AutomapBase.prepare`
-method will make use of the classes we've established based on the table name
-we use.  If our schema contains tables ``user`` and ``address``, we can define
-one or both of the classes to be used::
-
-    from sqlalchemy.ext.automap import automap_base
-    from sqlalchemy import create_engine
-
-    # automap base
-    Base = automap_base()
-
-    # pre-declare User for the 'user' table
-    class User(Base):
-        __tablename__ = 'user'
-
-        # override schema elements like Columns
-        user_name = Column('name', String)
-
-        # override relationships too, if desired.
-        # we must use the same name that automap would use for the relationship,
-        # and also must refer to the class name that automap will generate
-        # for "address"
-        address_collection = relationship("address", collection_class=set)
-
-    # reflect
-    engine = create_engine("sqlite:///mydatabase.db")
-    Base.prepare(engine, reflect=True)
-
-    # we still have Address generated from the tablename "address",
-    # but User is the same as Base.classes.User now
-
-    Address = Base.classes.address
-
-    u1 = session.query(User).first()
-    print (u1.address_collection)
-
-    # the backref is still there:
-    a1 = session.query(Address).first()
-    print (a1.user)
-
-Above, one of the more intricate details is that we illustrated overriding
-one of the :func:`.relationship` objects that automap would have created.
-To do this, we needed to make sure the names match up with what automap
-would normally generate, in that the relationship name would be ``User.address_collection``
-and the name of the class referred to, from automap's perspective, is called
-``address``, even though we are referring to it as ``Address`` within our usage
-of this class.
-
-Overriding Naming Schemes
-=========================
-
-:mod:`.sqlalchemy.ext.automap` is tasked with producing mapped classes and
-relationship names based on a schema, which means it has decision points in how
-these names are determined.  These three decision points are provided using
-functions which can be passed to the :meth:`.AutomapBase.prepare` method, and
-are known as :func:`.classname_for_table`,
-:func:`.name_for_scalar_relationship`,
-and :func:`.name_for_collection_relationship`.  Any or all of these
-functions are provided as in the example below, where we use a "camel case"
-scheme for class names and a "pluralizer" for collection names using the
-`Inflect <https://pypi.python.org/pypi/inflect>`_ package::
-
-    import re
-    import inflect
-
-    def camelize_classname(base, tablename, table):
-        "Produce a 'camelized' class name, e.g. "
-        "'words_and_underscores' -> 'WordsAndUnderscores'"
-
-        return str(tablename[0].upper() + \\
-                re.sub(r'_(\w)', lambda m: m.group(1).upper(), tablename[1:]))
-
-    _pluralizer = inflect.engine()
-    def pluralize_collection(base, local_cls, referred_cls, constraint):
-        "Produce an 'uncamelized', 'pluralized' class name, e.g. "
-        "'SomeTerm' -> 'some_terms'"
-
-        referred_name = referred_cls.__name__
-        uncamelized = referred_name[0].lower() + \\
-                        re.sub(r'\W',
-                                lambda m: "_%s" % m.group(0).lower(),
-                                referred_name[1:])
-        pluralized = _pluralizer.plural(uncamelized)
-        return pluralized
-
-    from sqlalchemy.ext.automap import automap_base
-
-    Base = automap_base()
-
-    engine = create_engine("sqlite:///mydatabase.db")
-
-    Base.prepare(engine, reflect=True,
-                classname_for_table=camelize_classname,
-                name_for_collection_relationship=pluralize_collection
-        )
-
-From the above mapping, we would now have classes ``User`` and ``Address``,
-where the collection from ``User`` to ``Address`` is called ``User.addresses``::
-
-    User, Address = Base.classes.User, Base.classes.Address
-
-    u1 = User(addresses=[Address(email="foo@bar.com")])
-
-Relationship Detection
-======================
-
-The vast majority of what automap accomplishes is the generation of
-:func:`.relationship` structures based on foreign keys.  The mechanism
-by which this works for many-to-one and one-to-many relationships is as follows:
-
-1. A given :class:`.Table`, known to be mapped to a particular class,
-   is examined for :class:`.ForeignKeyConstraint` objects.
-
-2. From each :class:`.ForeignKeyConstraint`, the remote :class:`.Table`
-   object present is matched up to the class to which it is to be mapped,
-   if any, else it is skipped.
-
-3. As the :class:`.ForeignKeyConstraint` we are examining correponds to a reference
-   from the immediate mapped class,
-   the relationship will be set up as a many-to-one referring to the referred class;
-   a corresponding one-to-many backref will be created on the referred class referring
-   to this class.
-
-4. The names of the relationships are determined using the
-   :paramref:`.AutomapBase.prepare.name_for_scalar_relationship` and
-   :paramref:`.AutomapBase.prepare.name_for_collection_relationship`
-   callable functions.  It is important to note that the default relationship
-   naming derives the name from the **the actual class name**.  If you've
-   given a particular class an explicit name by declaring it, or specified an
-   alternate class naming scheme, that's the name from which the relationship
-   name will be derived.
-
-5. The classes are inspected for an existing mapped property matching these
-   names.  If one is detected on one side, but none on the other side, :class:`.AutomapBase`
-   attempts to create a relationship on the missing side, then uses the
-   :paramref:`.relationship.back_populates` parameter in order to point
-   the new relationship to the other side.
-
-6. In the usual case where no relationship is on either side,
-   :meth:`.AutomapBase.prepare` produces a :func:`.relationship` on the "many-to-one"
-   side and matches it to the other using the :paramref:`.relationship.backref`
-   parameter.
-
-7. Production of the :func:`.relationship` and optionally the :func:`.backref`
-   is handed off to the :paramref:`.AutomapBase.prepare.generate_relationship`
-   function, which can be supplied by the end-user in order to augment
-   the arguments passed to :func:`.relationship` or :func:`.backref` or to
-   make use of custom implementations of these functions.
-
-Custom Relationship Arguments
------------------------------
-
-The :paramref:`.AutomapBase.prepare.generate_relationship` hook can be used
-to add parameters to relationships.  For most cases, we can make use of the
-existing :func:`.automap.generate_relationship` function to return
-the object, after augmenting the given keyword dictionary with our own
-arguments.
-
-Below is an illustration of how to send
-:paramref:`.relationship.cascade` and
-:paramref:`.relationship.passive_deletes`
-options along to all one-to-many relationships::
-
-    from sqlalchemy.ext.automap import generate_relationship
-
-    def _gen_relationship(base, direction, return_fn,
-                                    attrname, local_cls, referred_cls, **kw):
-        if direction is interfaces.ONETOMANY:
-            kw['cascade'] = 'all, delete-orphan'
-            kw['passive_deletes'] = True
-        # make use of the built-in function to actually return
-        # the result.
-        return generate_relationship(base, direction, return_fn,
-                                        attrname, local_cls, referred_cls, **kw)
-
-    from sqlalchemy.ext.automap import automap_base
-    from sqlalchemy import create_engine
-
-    # automap base
-    Base = automap_base()
-
-    engine = create_engine("sqlite:///mydatabase.db")
-    Base.prepare(engine, reflect=True,
-                generate_relationship=_gen_relationship)
-
-Many-to-Many relationships
---------------------------
-
-:mod:`.sqlalchemy.ext.automap` will generate many-to-many relationships, e.g.
-those which contain a ``secondary`` argument.  The process for producing these
-is as follows:
-
-1. A given :class:`.Table` is examined for :class:`.ForeignKeyConstraint` objects,
-   before any mapped class has been assigned to it.
-
-2. If the table contains two and exactly two :class:`.ForeignKeyConstraint`
-   objects, and all columns within this table are members of these two
-   :class:`.ForeignKeyConstraint` objects, the table is assumed to be a
-   "secondary" table, and will **not be mapped directly**.
-
-3. The two (or one, for self-referential) external tables to which the :class:`.Table`
-   refers to are matched to the classes to which they will be mapped, if any.
-
-4. If mapped classes for both sides are located, a many-to-many bi-directional
-   :func:`.relationship` / :func:`.backref` pair is created between the two
-   classes.
-
-5. The override logic for many-to-many works the same as that of one-to-many/
-   many-to-one; the :func:`.generate_relationship` function is called upon
-   to generate the strucures and existing attributes will be maintained.
-
-Relationships with Inheritance
-------------------------------
-
-:mod:`.sqlalchemy.ext.automap` will not generate any relationships between
-two classes that are in an inheritance relationship.   That is, with two classes
-given as follows::
-
-    class Employee(Base):
-        __tablename__ = 'employee'
-        id = Column(Integer, primary_key=True)
-        type = Column(String(50))
-        __mapper_args__ = {
-             'polymorphic_identity':'employee', 'polymorphic_on': type
-        }
-
-    class Engineer(Employee):
-        __tablename__ = 'engineer'
-        id = Column(Integer, ForeignKey('employee.id'), primary_key=True)
-        __mapper_args__ = {
-            'polymorphic_identity':'engineer',
-        }
-
-The foreign key from ``Engineer`` to ``Employee`` is used not for a relationship,
-but to establish joined inheritance between the two classes.
-
-Note that this means automap will not generate *any* relationships
-for foreign keys that link from a subclass to a superclass.  If a mapping
-has actual relationships from subclass to superclass as well, those
-need to be explicit.  Below, as we have two separate foreign keys
-from ``Engineer`` to ``Employee``, we need to set up both the relationship
-we want as well as the ``inherit_condition``, as these are not things
-SQLAlchemy can guess::
-
-    class Employee(Base):
-        __tablename__ = 'employee'
-        id = Column(Integer, primary_key=True)
-        type = Column(String(50))
-
-        __mapper_args__ = {
-            'polymorphic_identity':'employee', 'polymorphic_on':type
-        }
-
-    class Engineer(Employee):
-        __tablename__ = 'engineer'
-        id = Column(Integer, ForeignKey('employee.id'), primary_key=True)
-        favorite_employee_id = Column(Integer, ForeignKey('employee.id'))
-
-        favorite_employee = relationship(Employee, foreign_keys=favorite_employee_id)
-
-        __mapper_args__ = {
-            'polymorphic_identity':'engineer',
-            'inherit_condition': id == Employee.id
-        }
-
-
-Using Automap with Explicit Declarations
-========================================
-
-As noted previously, automap has no dependency on reflection, and can make
-use of any collection of :class:`.Table` objects within a :class:`.MetaData`
-collection.  From this, it follows that automap can also be used
-generate missing relationships given an otherwise complete model that fully defines
-table metadata::
-
-    from sqlalchemy.ext.automap import automap_base
-    from sqlalchemy import Column, Integer, String, ForeignKey
-
-    Base = automap_base()
-
-    class User(Base):
-        __tablename__ = 'user'
-
-        id = Column(Integer, primary_key=True)
-        name = Column(String)
-
-    class Address(Base):
-        __tablename__ = 'address'
-
-        id = Column(Integer, primary_key=True)
-        email = Column(String)
-        user_id = Column(ForeignKey('user.id'))
-
-    # produce relationships
-    Base.prepare()
-
-    # mapping is complete, with "address_collection" and
-    # "user" relationships
-    a1 = Address(email='u1')
-    a2 = Address(email='u2')
-    u1 = User(address_collection=[a1, a2])
-    assert a1.user is u1
-
-Above, given mostly complete ``User`` and ``Address`` mappings, the
-:class:`.ForeignKey` which we defined on ``Address.user_id`` allowed a
-bidirectional relationship pair ``Address.user`` and ``User.address_collection``
-to be generated on the mapped classes.
-
-Note that when subclassing :class:`.AutomapBase`, the :meth:`.AutomapBase.prepare`
-method is required; if not called, the classes we've declared are in an
-un-mapped state.

-"""Provides an API for creation of custom ClauseElements and compilers.
-
-Synopsis
-========
-
-Usage involves the creation of one or more
-:class:`~sqlalchemy.sql.expression.ClauseElement` subclasses and one or
-more callables defining its compilation::
-
-    from sqlalchemy.ext.compiler import compiles
-    from sqlalchemy.sql.expression import ColumnClause
-
-    class MyColumn(ColumnClause):
-        pass
-
-    @compiles(MyColumn)
-    def compile_mycolumn(element, compiler, **kw):
-        return "[%s]" % element.name
-
-Above, ``MyColumn`` extends :class:`~sqlalchemy.sql.expression.ColumnClause`,
-the base expression element for named column objects. The ``compiles``
-decorator registers itself with the ``MyColumn`` class so that it is invoked
-when the object is compiled to a string::
-
-    from sqlalchemy import select
-
-    s = select([MyColumn('x'), MyColumn('y')])
-    print str(s)
-
-Produces::
-
-    SELECT [x], [y]
-
-Dialect-specific compilation rules
-==================================
-
-Compilers can also be made dialect-specific. The appropriate compiler will be
-invoked for the dialect in use::
-
-    from sqlalchemy.schema import DDLElement
-
-    class AlterColumn(DDLElement):
-
-        def __init__(self, column, cmd):
-            self.column = column
-            self.cmd = cmd
-
-    @compiles(AlterColumn)
-    def visit_alter_column(element, compiler, **kw):
-        return "ALTER COLUMN %s ..." % element.column.name
-
-    @compiles(AlterColumn, 'postgresql')
-    def visit_alter_column(element, compiler, **kw):
-        return "ALTER TABLE %s ALTER COLUMN %s ..." % (element.table.name, element.column.name)
-
-The second ``visit_alter_table`` will be invoked when any ``postgresql``
-dialect is used.
-
-Compiling sub-elements of a custom expression construct
-=======================================================
-
-The ``compiler`` argument is the
-:class:`~sqlalchemy.engine.interfaces.Compiled` object in use. This object
-can be inspected for any information about the in-progress compilation,
-including ``compiler.dialect``, ``compiler.statement`` etc. The
-:class:`~sqlalchemy.sql.compiler.SQLCompiler` and
-:class:`~sqlalchemy.sql.compiler.DDLCompiler` both include a ``process()``
-method which can be used for compilation of embedded attributes::
-
-    from sqlalchemy.sql.expression import Executable, ClauseElement
-
-    class InsertFromSelect(Executable, ClauseElement):
-        def __init__(self, table, select):
-            self.table = table
-            self.select = select
-
-    @compiles(InsertFromSelect)
-    def visit_insert_from_select(element, compiler, **kw):
-        return "INSERT INTO %s (%s)" % (
-            compiler.process(element.table, asfrom=True),
-            compiler.process(element.select)
-        )
-
-    insert = InsertFromSelect(t1, select([t1]).where(t1.c.x>5))
-    print insert
-
-Produces::
-
-    "INSERT INTO mytable (SELECT mytable.x, mytable.y, mytable.z FROM mytable WHERE mytable.x > :x_1)"
-
-.. note::
-
-    The above ``InsertFromSelect`` construct is only an example, this actual
-    functionality is already available using the
-    :meth:`.Insert.from_select` method.
-
-.. note::
-
-   The above ``InsertFromSelect`` construct probably wants to have "autocommit"
-   enabled.  See :ref:`enabling_compiled_autocommit` for this step.
-
-Cross Compiling between SQL and DDL compilers
----------------------------------------------
-
-SQL and DDL constructs are each compiled using different base compilers -
-``SQLCompiler`` and ``DDLCompiler``.   A common need is to access the
-compilation rules of SQL expressions from within a DDL expression. The
-``DDLCompiler`` includes an accessor ``sql_compiler`` for this reason, such as
-below where we generate a CHECK constraint that embeds a SQL expression::
-
-    @compiles(MyConstraint)
-    def compile_my_constraint(constraint, ddlcompiler, **kw):
-        return "CONSTRAINT %s CHECK (%s)" % (
-            constraint.name,
-            ddlcompiler.sql_compiler.process(constraint.expression)
-        )
-
-.. _enabling_compiled_autocommit:
-
-Enabling Autocommit on a Construct
-==================================
-
-Recall from the section :ref:`autocommit` that the :class:`.Engine`, when
-asked to execute a construct in the absence of a user-defined transaction,
-detects if the given construct represents DML or DDL, that is, a data
-modification or data definition statement, which requires (or may require,
-in the case of DDL) that the transaction generated by the DBAPI be committed
-(recall that DBAPI always has a transaction going on regardless of what
-SQLAlchemy does).   Checking for this is actually accomplished by checking for
-the "autocommit" execution option on the construct.    When building a
-construct like an INSERT derivation, a new DDL type, or perhaps a stored
-procedure that alters data, the "autocommit" option needs to be set in order
-for the statement to function with "connectionless" execution
-(as described in :ref:`dbengine_implicit`).
-
-Currently a quick way to do this is to subclass :class:`.Executable`, then
-add the "autocommit" flag to the ``_execution_options`` dictionary (note this
-is a "frozen" dictionary which supplies a generative ``union()`` method)::
-
-    from sqlalchemy.sql.expression import Executable, ClauseElement
-
-    class MyInsertThing(Executable, ClauseElement):
-        _execution_options = \\
-            Executable._execution_options.union({'autocommit': True})
-
-More succinctly, if the construct is truly similar to an INSERT, UPDATE, or
-DELETE, :class:`.UpdateBase` can be used, which already is a subclass
-of :class:`.Executable`, :class:`.ClauseElement` and includes the
-``autocommit`` flag::
-
-    from sqlalchemy.sql.expression import UpdateBase
-
-    class MyInsertThing(UpdateBase):
-        def __init__(self, ...):
-            ...
-
-
-
-
-DDL elements that subclass :class:`.DDLElement` already have the
-"autocommit" flag turned on.
-
-
-
-
-Changing the default compilation of existing constructs
-=======================================================
-
-The compiler extension applies just as well to the existing constructs.  When
-overriding the compilation of a built in SQL construct, the @compiles
-decorator is invoked upon the appropriate class (be sure to use the class,
-i.e. ``Insert`` or ``Select``, instead of the creation function such
-as ``insert()`` or ``select()``).
-
-Within the new compilation function, to get at the "original" compilation
-routine, use the appropriate visit_XXX method - this
-because compiler.process() will call upon the overriding routine and cause
-an endless loop.   Such as, to add "prefix" to all insert statements::
-
-    from sqlalchemy.sql.expression import Insert
-
-    @compiles(Insert)
-    def prefix_inserts(insert, compiler, **kw):
-        return compiler.visit_insert(insert.prefix_with("some prefix"), **kw)
-
-The above compiler will prefix all INSERT statements with "some prefix" when
-compiled.
-
-.. _type_compilation_extension:
-
-Changing Compilation of Types
-=============================
-
-``compiler`` works for types, too, such as below where we implement the
-MS-SQL specific 'max' keyword for ``String``/``VARCHAR``::
-
-    @compiles(String, 'mssql')
-    @compiles(VARCHAR, 'mssql')
-    def compile_varchar(element, compiler, **kw):
-        if element.length == 'max':
-            return "VARCHAR('max')"
-        else:
-            return compiler.visit_VARCHAR(element, **kw)
-
-    foo = Table('foo', metadata,
-        Column('data', VARCHAR('max'))
-    )
-
-Subclassing Guidelines
-======================
-
-A big part of using the compiler extension is subclassing SQLAlchemy
-expression constructs. To make this easier, the expression and
-schema packages feature a set of "bases" intended for common tasks.
-A synopsis is as follows:
-
-* :class:`~sqlalchemy.sql.expression.ClauseElement` - This is the root
-  expression class. Any SQL expression can be derived from this base, and is
-  probably the best choice for longer constructs such as specialized INSERT
-  statements.
-
-* :class:`~sqlalchemy.sql.expression.ColumnElement` - The root of all
-  "column-like" elements. Anything that you'd place in the "columns" clause of
-  a SELECT statement (as well as order by and group by) can derive from this -
-  the object will automatically have Python "comparison" behavior.
-
-  :class:`~sqlalchemy.sql.expression.ColumnElement` classes want to have a
-  ``type`` member which is expression's return type.  This can be established
-  at the instance level in the constructor, or at the class level if its
-  generally constant::
-
-      class timestamp(ColumnElement):
-          type = TIMESTAMP()
-
-* :class:`~sqlalchemy.sql.functions.FunctionElement` - This is a hybrid of a
-  ``ColumnElement`` and a "from clause" like object, and represents a SQL
-  function or stored procedure type of call. Since most databases support
-  statements along the line of "SELECT FROM <some function>"
-  ``FunctionElement`` adds in the ability to be used in the FROM clause of a
-  ``select()`` construct::
-
-      from sqlalchemy.sql.expression import FunctionElement
-
-      class coalesce(FunctionElement):
-          name = 'coalesce'
-
-      @compiles(coalesce)
-      def compile(element, compiler, **kw):
-          return "coalesce(%s)" % compiler.process(element.clauses)
-
-      @compiles(coalesce, 'oracle')
-      def compile(element, compiler, **kw):
-          if len(element.clauses) > 2:
-              raise TypeError("coalesce only supports two arguments on Oracle")
-          return "nvl(%s)" % compiler.process(element.clauses)
-
-* :class:`~sqlalchemy.schema.DDLElement` - The root of all DDL expressions,
-  like CREATE TABLE, ALTER TABLE, etc. Compilation of ``DDLElement``
-  subclasses is issued by a ``DDLCompiler`` instead of a ``SQLCompiler``.
-  ``DDLElement`` also features ``Table`` and ``MetaData`` event hooks via the
-  ``execute_at()`` method, allowing the construct to be invoked during CREATE
-  TABLE and DROP TABLE sequences.
-
-* :class:`~sqlalchemy.sql.expression.Executable` - This is a mixin which
-  should be used with any expression class that represents a "standalone"
-  SQL statement that can be passed directly to an ``execute()`` method.  It
-  is already implicit within ``DDLElement`` and ``FunctionElement``.
-
-Further Examples
-================
-
-"UTC timestamp" function
--------------------------
-
-A function that works like "CURRENT_TIMESTAMP" except applies the
-appropriate conversions so that the time is in UTC time.   Timestamps are best
-stored in relational databases as UTC, without time zones.   UTC so that your
-database doesn't think time has gone backwards in the hour when daylight
-savings ends, without timezones because timezones are like character
-encodings - they're best applied only at the endpoints of an application
-(i.e. convert to UTC upon user input, re-apply desired timezone upon display).
-
-For Postgresql and Microsoft SQL Server::
-
-    from sqlalchemy.sql import expression
-    from sqlalchemy.ext.compiler import compiles
-    from sqlalchemy.types import DateTime
-
-    class utcnow(expression.FunctionElement):
-        type = DateTime()
-
-    @compiles(utcnow, 'postgresql')
-    def pg_utcnow(element, compiler, **kw):
-        return "TIMEZONE('utc', CURRENT_TIMESTAMP)"
-
-    @compiles(utcnow, 'mssql')
-    def ms_utcnow(element, compiler, **kw):
-        return "GETUTCDATE()"
-
-Example usage::
-
-    from sqlalchemy import (
-                Table, Column, Integer, String, DateTime, MetaData
-            )
-    metadata = MetaData()
-    event = Table("event", metadata,
-        Column("id", Integer, primary_key=True),
-        Column("description", String(50), nullable=False),
-        Column("timestamp", DateTime, server_default=utcnow())
-    )
-
-"GREATEST" function
--------------------
-
-The "GREATEST" function is given any number of arguments and returns the one
-that is of the highest value - it's equivalent to Python's ``max``
-function.  A SQL standard version versus a CASE based version which only
-accommodates two arguments::
-
-    from sqlalchemy.sql import expression
-    from sqlalchemy.ext.compiler import compiles
-    from sqlalchemy.types import Numeric
-
-    class greatest(expression.FunctionElement):
-        type = Numeric()
-        name = 'greatest'
-
-    @compiles(greatest)
-    def default_greatest(element, compiler, **kw):
-        return compiler.visit_function(element)
-
-    @compiles(greatest, 'sqlite')
-    @compiles(greatest, 'mssql')
-    @compiles(greatest, 'oracle')
-    def case_greatest(element, compiler, **kw):
-        arg1, arg2 = list(element.clauses)
-        return "CASE WHEN %s > %s THEN %s ELSE %s END" % (
-            compiler.process(arg1),
-            compiler.process(arg2),
-            compiler.process(arg1),
-            compiler.process(arg2),
-        )
-
-Example usage::
-
-    Session.query(Account).\\
-            filter(
-                greatest(
-                    Account.checking_balance,
-                    Account.savings_balance) > 10000
-            )
-
-"false" expression
-------------------
-
-Render a "false" constant expression, rendering as "0" on platforms that
-don't have a "false" constant::
-
-    from sqlalchemy.sql import expression
-    from sqlalchemy.ext.compiler import compiles
-
-    class sql_false(expression.ColumnElement):
-        pass
-
-    @compiles(sql_false)
-    def default_false(element, compiler, **kw):
-        return "false"
-
-    @compiles(sql_false, 'mssql')
-    @compiles(sql_false, 'mysql')
-    @compiles(sql_false, 'oracle')
-    def int_false(element, compiler, **kw):
-        return "0"
-
-Example usage::
-
-    from sqlalchemy import select, union_all
-
-    exp = union_all(
-        select([users.c.name, sql_false().label("enrolled")]),
-        select([customers.c.name, customers.c.enrolled])
-    )

-Synopsis
-========
-
-SQLAlchemy object-relational configuration involves the
-combination of :class:`.Table`, :func:`.mapper`, and class
-objects to define a mapped class.
-:mod:`~sqlalchemy.ext.declarative` allows all three to be
-expressed at once within the class declaration. As much as
-possible, regular SQLAlchemy schema and ORM constructs are
-used directly, so that configuration between "classical" ORM
-usage and declarative remain highly similar.
-
-As a simple example::
-
-    from sqlalchemy.ext.declarative import declarative_base
-
-    Base = declarative_base()
-
-    class SomeClass(Base):
-        __tablename__ = 'some_table'
-        id = Column(Integer, primary_key=True)
-        name =  Column(String(50))
-
-Above, the :func:`declarative_base` callable returns a new base class from
-which all mapped classes should inherit. When the class definition is
-completed, a new :class:`.Table` and :func:`.mapper` will have been generated.
-
-The resulting table and mapper are accessible via
-``__table__`` and ``__mapper__`` attributes on the
-``SomeClass`` class::
-
-    # access the mapped Table
-    SomeClass.__table__
-
-    # access the Mapper
-    SomeClass.__mapper__
-
-Defining Attributes
-===================
-
-In the previous example, the :class:`.Column` objects are
-automatically named with the name of the attribute to which they are
-assigned.
-
-To name columns explicitly with a name distinct from their mapped attribute,
-just give the column a name.  Below, column "some_table_id" is mapped to the
-"id" attribute of `SomeClass`, but in SQL will be represented as
-"some_table_id"::
-
-    class SomeClass(Base):
-        __tablename__ = 'some_table'
-        id = Column("some_table_id", Integer, primary_key=True)
-
-Attributes may be added to the class after its construction, and they will be
-added to the underlying :class:`.Table` and
-:func:`.mapper` definitions as appropriate::
-
-    SomeClass.data = Column('data', Unicode)
-    SomeClass.related = relationship(RelatedInfo)
-
-Classes which are constructed using declarative can interact freely
-with classes that are mapped explicitly with :func:`.mapper`.
-
-It is recommended, though not required, that all tables
-share the same underlying :class:`~sqlalchemy.schema.MetaData` object,
-so that string-configured :class:`~sqlalchemy.schema.ForeignKey`
-references can be resolved without issue.
-
-Accessing the MetaData
-=======================
-
-The :func:`declarative_base` base class contains a
-:class:`.MetaData` object where newly defined
-:class:`.Table` objects are collected. This object is
-intended to be accessed directly for
-:class:`.MetaData`-specific operations. Such as, to issue
-CREATE statements for all tables::
-
-    engine = create_engine('sqlite://')
-    Base.metadata.create_all(engine)
-
-:func:`declarative_base` can also receive a pre-existing
-:class:`.MetaData` object, which allows a
-declarative setup to be associated with an already
-existing traditional collection of :class:`~sqlalchemy.schema.Table`
-objects::
-
-    mymetadata = MetaData()
-    Base = declarative_base(metadata=mymetadata)
-
-
-.. _declarative_configuring_relationships:
-
-Configuring Relationships
-=========================
-
-Relationships to other classes are done in the usual way, with the added
-feature that the class specified to :func:`~sqlalchemy.orm.relationship`
-may be a string name.  The "class registry" associated with ``Base``
-is used at mapper compilation time to resolve the name into the actual
-class object, which is expected to have been defined once the mapper
-configuration is used::
-
-    class User(Base):
-        __tablename__ = 'users'
-
-        id = Column(Integer, primary_key=True)
-        name = Column(String(50))
-        addresses = relationship("Address", backref="user")
-
-    class Address(Base):
-        __tablename__ = 'addresses'
-
-        id = Column(Integer, primary_key=True)
-        email = Column(String(50))
-        user_id = Column(Integer, ForeignKey('users.id'))
-
-Column constructs, since they are just that, are immediately usable,
-as below where we define a primary join condition on the ``Address``
-class using them::
-
-    class Address(Base):
-        __tablename__ = 'addresses'
-
-        id = Column(Integer, primary_key=True)
-        email = Column(String(50))
-        user_id = Column(Integer, ForeignKey('users.id'))
-        user = relationship(User, primaryjoin=user_id == User.id)
-
-In addition to the main argument for :func:`~sqlalchemy.orm.relationship`,
-other arguments which depend upon the columns present on an as-yet
-undefined class may also be specified as strings.  These strings are
-evaluated as Python expressions.  The full namespace available within
-this evaluation includes all classes mapped for this declarative base,
-as well as the contents of the ``sqlalchemy`` package, including
-expression functions like :func:`~sqlalchemy.sql.expression.desc` and
-:attr:`~sqlalchemy.sql.expression.func`::
-
-    class User(Base):
-        # ....
-        addresses = relationship("Address",
-                             order_by="desc(Address.email)",
-                             primaryjoin="Address.user_id==User.id")
-
-For the case where more than one module contains a class of the same name,
-string class names can also be specified as module-qualified paths
-within any of these string expressions::
-
-    class User(Base):
-        # ....
-        addresses = relationship("myapp.model.address.Address",
-                             order_by="desc(myapp.model.address.Address.email)",
-                             primaryjoin="myapp.model.address.Address.user_id=="
-                                            "myapp.model.user.User.id")
-
-The qualified path can be any partial path that removes ambiguity between
-the names.  For example, to disambiguate between
-``myapp.model.address.Address`` and ``myapp.model.lookup.Address``,
-we can specify ``address.Address`` or ``lookup.Address``::
-
-    class User(Base):
-        # ....
-        addresses = relationship("address.Address",
-                             order_by="desc(address.Address.email)",
-                             primaryjoin="address.Address.user_id=="
-                                            "User.id")
-
-.. versionadded:: 0.8
-   module-qualified paths can be used when specifying string arguments
-   with Declarative, in order to specify specific modules.
-
-Two alternatives also exist to using string-based attributes.  A lambda
-can also be used, which will be evaluated after all mappers have been
-configured::
-
-    class User(Base):
-        # ...
-        addresses = relationship(lambda: Address,
-                             order_by=lambda: desc(Address.email),
-                             primaryjoin=lambda: Address.user_id==User.id)
-
-Or, the relationship can be added to the class explicitly after the classes
-are available::
-
-    User.addresses = relationship(Address,
-                              primaryjoin=Address.user_id==User.id)
-
-
-
-.. _declarative_many_to_many:
-
-Configuring Many-to-Many Relationships
-======================================
-
-Many-to-many relationships are also declared in the same way
-with declarative as with traditional mappings. The
-``secondary`` argument to
-:func:`.relationship` is as usual passed a
-:class:`.Table` object, which is typically declared in the
-traditional way.  The :class:`.Table` usually shares
-the :class:`.MetaData` object used by the declarative base::
-
-    keywords = Table(
-        'keywords', Base.metadata,
-        Column('author_id', Integer, ForeignKey('authors.id')),
-        Column('keyword_id', Integer, ForeignKey('keywords.id'))
-        )
-
-    class Author(Base):
-        __tablename__ = 'authors'
-        id = Column(Integer, primary_key=True)
-        keywords = relationship("Keyword", secondary=keywords)
-
-Like other :func:`~sqlalchemy.orm.relationship` arguments, a string is accepted
-as well, passing the string name of the table as defined in the
-``Base.metadata.tables`` collection::
-
-    class Author(Base):
-        __tablename__ = 'authors'
-        id = Column(Integer, primary_key=True)
-        keywords = relationship("Keyword", secondary="keywords")
-
-As with traditional mapping, its generally not a good idea to use
-a :class:`.Table` as the "secondary" argument which is also mapped to
-a class, unless the :func:`.relationship` is declared with ``viewonly=True``.
-Otherwise, the unit-of-work system may attempt duplicate INSERT and
-DELETE statements against the underlying table.

-.. _declarative_sql_expressions:
-
-Defining SQL Expressions
-========================
-
-See :ref:`mapper_sql_expressions` for examples on declaratively
-mapping attributes to SQL expressions.
-
-.. _declarative_table_args:
-
-Table Configuration
-===================
-
-Table arguments other than the name, metadata, and mapped Column
-arguments are specified using the ``__table_args__`` class attribute.
-This attribute accommodates both positional as well as keyword
-arguments that are normally sent to the
-:class:`~sqlalchemy.schema.Table` constructor.
-The attribute can be specified in one of two forms. One is as a
-dictionary::
-
-    class MyClass(Base):
-        __tablename__ = 'sometable'
-        __table_args__ = {'mysql_engine':'InnoDB'}
-
-The other, a tuple, where each argument is positional
-(usually constraints)::
-
-    class MyClass(Base):
-        __tablename__ = 'sometable'
-        __table_args__ = (
-                ForeignKeyConstraint(['id'], ['remote_table.id']),
-                UniqueConstraint('foo'),
-                )
-
-Keyword arguments can be specified with the above form by
-specifying the last argument as a dictionary::
-
-    class MyClass(Base):
-        __tablename__ = 'sometable'
-        __table_args__ = (
-                ForeignKeyConstraint(['id'], ['remote_table.id']),
-                UniqueConstraint('foo'),
-                {'autoload':True}
-                )
-
-Using a Hybrid Approach with __table__
-=======================================
-
-As an alternative to ``__tablename__``, a direct
-:class:`~sqlalchemy.schema.Table` construct may be used.  The
-:class:`~sqlalchemy.schema.Column` objects, which in this case require
-their names, will be added to the mapping just like a regular mapping
-to a table::
-
-    class MyClass(Base):
-        __table__ = Table('my_table', Base.metadata,
-            Column('id', Integer, primary_key=True),
-            Column('name', String(50))
-        )
-
-``__table__`` provides a more focused point of control for establishing
-table metadata, while still getting most of the benefits of using declarative.
-An application that uses reflection might want to load table metadata elsewhere
-and pass it to declarative classes::
-
-    from sqlalchemy.ext.declarative import declarative_base
-
-    Base = declarative_base()
-    Base.metadata.reflect(some_engine)
-
-    class User(Base):
-        __table__ = metadata.tables['user']
-
-    class Address(Base):
-        __table__ = metadata.tables['address']
-
-Some configuration schemes may find it more appropriate to use ``__table__``,
-such as those which already take advantage of the data-driven nature of
-:class:`.Table` to customize and/or automate schema definition.
-
-Note that when the ``__table__`` approach is used, the object is immediately
-usable as a plain :class:`.Table` within the class declaration body itself,
-as a Python class is only another syntactical block.  Below this is illustrated
-by using the ``id`` column in the ``primaryjoin`` condition of a
-:func:`.relationship`::
-
-    class MyClass(Base):
-        __table__ = Table('my_table', Base.metadata,
-            Column('id', Integer, primary_key=True),
-            Column('name', String(50))
-        )
-
-        widgets = relationship(Widget,
-                    primaryjoin=Widget.myclass_id==__table__.c.id)
-
-Similarly, mapped attributes which refer to ``__table__`` can be placed inline,
-as below where we assign the ``name`` column to the attribute ``_name``,
-generating a synonym for ``name``::
-
-    from sqlalchemy.ext.declarative import synonym_for
-
-    class MyClass(Base):
-        __table__ = Table('my_table', Base.metadata,
-            Column('id', Integer, primary_key=True),
-            Column('name', String(50))
-        )
-
-        _name = __table__.c.name
-
-        @synonym_for("_name")
-        def name(self):
-            return "Name: %s" % _name
-
-Using Reflection with Declarative
-=================================
-
-It's easy to set up a :class:`.Table` that uses ``autoload=True``
-in conjunction with a mapped class::
-
-    class MyClass(Base):
-        __table__ = Table('mytable', Base.metadata,
-                        autoload=True, autoload_with=some_engine)
-
-However, one improvement that can be made here is to not
-require the :class:`.Engine` to be available when classes are
-being first declared.   To achieve this, use the
-:class:`.DeferredReflection` mixin, which sets up mappings
-only after a special ``prepare(engine)`` step is called::
-
-    from sqlalchemy.ext.declarative import declarative_base, DeferredReflection
-
-    Base = declarative_base(cls=DeferredReflection)
-
-    class Foo(Base):
-        __tablename__ = 'foo'
-        bars = relationship("Bar")
-
-    class Bar(Base):
-        __tablename__ = 'bar'
-
-        # illustrate overriding of "bar.foo_id" to have
-        # a foreign key constraint otherwise not
-        # reflected, such as when using MySQL
-        foo_id = Column(Integer, ForeignKey('foo.id'))
-
-    Base.prepare(e)
-
-.. versionadded:: 0.8
-   Added :class:`.DeferredReflection`.
-
-Mapper Configuration
-====================
-
-Declarative makes use of the :func:`~.orm.mapper` function internally
-when it creates the mapping to the declared table.   The options
-for :func:`~.orm.mapper` are passed directly through via the
-``__mapper_args__`` class attribute.  As always, arguments which reference
-locally mapped columns can reference them directly from within the
-class declaration::
-
-    from datetime import datetime
-
-    class Widget(Base):
-        __tablename__ = 'widgets'
-
-        id = Column(Integer, primary_key=True)
-        timestamp = Column(DateTime, nullable=False)
-
-        __mapper_args__ = {
-                        'version_id_col': timestamp,
-                        'version_id_generator': lambda v:datetime.now()
-                    }
-
-.. _declarative_inheritance:
-
-Inheritance Configuration
-=========================
-
-Declarative supports all three forms of inheritance as intuitively
-as possible.  The ``inherits`` mapper keyword argument is not needed
-as declarative will determine this from the class itself.   The various
-"polymorphic" keyword arguments are specified using ``__mapper_args__``.
-
-Joined Table Inheritance
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-Joined table inheritance is defined as a subclass that defines its own
-table::
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        __tablename__ = 'engineers'
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-        id = Column(Integer, ForeignKey('people.id'), primary_key=True)
-        primary_language = Column(String(50))
-
-Note that above, the ``Engineer.id`` attribute, since it shares the
-same attribute name as the ``Person.id`` attribute, will in fact
-represent the ``people.id`` and ``engineers.id`` columns together,
-with the "Engineer.id" column taking precedence if queried directly.
-To provide the ``Engineer`` class with an attribute that represents
-only the ``engineers.id`` column, give it a different attribute name::
-
-    class Engineer(Person):
-        __tablename__ = 'engineers'
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-        engineer_id = Column('id', Integer, ForeignKey('people.id'),
-                                                    primary_key=True)
-        primary_language = Column(String(50))
-
-
-.. versionchanged:: 0.7 joined table inheritance favors the subclass
-   column over that of the superclass, such as querying above
-   for ``Engineer.id``.  Prior to 0.7 this was the reverse.
-
-.. _declarative_single_table:
-
-Single Table Inheritance
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-Single table inheritance is defined as a subclass that does not have
-its own table; you just leave out the ``__table__`` and ``__tablename__``
-attributes::
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-        primary_language = Column(String(50))
-
-When the above mappers are configured, the ``Person`` class is mapped
-to the ``people`` table *before* the ``primary_language`` column is
-defined, and this column will not be included in its own mapping.
-When ``Engineer`` then defines the ``primary_language`` column, the
-column is added to the ``people`` table so that it is included in the
-mapping for ``Engineer`` and is also part of the table's full set of
-columns.  Columns which are not mapped to ``Person`` are also excluded
-from any other single or joined inheriting classes using the
-``exclude_properties`` mapper argument.  Below, ``Manager`` will have
-all the attributes of ``Person`` and ``Manager`` but *not* the
-``primary_language`` attribute of ``Engineer``::
-
-    class Manager(Person):
-        __mapper_args__ = {'polymorphic_identity': 'manager'}
-        golf_swing = Column(String(50))
-
-The attribute exclusion logic is provided by the
-``exclude_properties`` mapper argument, and declarative's default
-behavior can be disabled by passing an explicit ``exclude_properties``
-collection (empty or otherwise) to the ``__mapper_args__``.
-
-Resolving Column Conflicts
-^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Note above that the ``primary_language`` and ``golf_swing`` columns
-are "moved up" to be applied to ``Person.__table__``, as a result of their
-declaration on a subclass that has no table of its own.   A tricky case
-comes up when two subclasses want to specify *the same* column, as below::
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-        start_date = Column(DateTime)
-
-    class Manager(Person):
-        __mapper_args__ = {'polymorphic_identity': 'manager'}
-        start_date = Column(DateTime)
-
-Above, the ``start_date`` column declared on both ``Engineer`` and ``Manager``
-will result in an error::
-
-    sqlalchemy.exc.ArgumentError: Column 'start_date' on class
-    <class '__main__.Manager'> conflicts with existing
-    column 'people.start_date'
-
-In a situation like this, Declarative can't be sure
-of the intent, especially if the ``start_date`` columns had, for example,
-different types.   A situation like this can be resolved by using
-:class:`.declared_attr` to define the :class:`.Column` conditionally, taking
-care to return the **existing column** via the parent ``__table__`` if it
-already exists::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-
-        @declared_attr
-        def start_date(cls):
-            "Start date column, if not present already."
-            return Person.__table__.c.get('start_date', Column(DateTime))
-
-    class Manager(Person):
-        __mapper_args__ = {'polymorphic_identity': 'manager'}
-
-        @declared_attr
-        def start_date(cls):
-            "Start date column, if not present already."
-            return Person.__table__.c.get('start_date', Column(DateTime))
-
-Above, when ``Manager`` is mapped, the ``start_date`` column is
-already present on the ``Person`` class.  Declarative lets us return
-that :class:`.Column` as a result in this case, where it knows to skip
-re-assigning the same column. If the mapping is mis-configured such
-that the ``start_date`` column is accidentally re-assigned to a
-different table (such as, if we changed ``Manager`` to be joined
-inheritance without fixing ``start_date``), an error is raised which
-indicates an existing :class:`.Column` is trying to be re-assigned to
-a different owning :class:`.Table`.
-
-.. versionadded:: 0.8 :class:`.declared_attr` can be used on a non-mixin
-   class, and the returned :class:`.Column` or other mapped attribute
-   will be applied to the mapping as any other attribute.  Previously,
-   the resulting attribute would be ignored, and also result in a warning
-   being emitted when a subclass was created.
-
-.. versionadded:: 0.8 :class:`.declared_attr`, when used either with a
-   mixin or non-mixin declarative class, can return an existing
-   :class:`.Column` already assigned to the parent :class:`.Table`,
-   to indicate that the re-assignment of the :class:`.Column` should be
-   skipped, however should still be mapped on the target class,
-   in order to resolve duplicate column conflicts.
-
-The same concept can be used with mixin classes (see
-:ref:`declarative_mixins`)::
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class HasStartDate(object):
-        @declared_attr
-        def start_date(cls):
-            return cls.__table__.c.get('start_date', Column(DateTime))
-
-    class Engineer(HasStartDate, Person):
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-
-    class Manager(HasStartDate, Person):
-        __mapper_args__ = {'polymorphic_identity': 'manager'}
-
-The above mixin checks the local ``__table__`` attribute for the column.
-Because we're using single table inheritance, we're sure that in this case,
-``cls.__table__`` refers to ``People.__table__``.  If we were mixing joined-
-and single-table inheritance, we might want our mixin to check more carefully
-if ``cls.__table__`` is really the :class:`.Table` we're looking for.
-
-Concrete Table Inheritance
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Concrete is defined as a subclass which has its own table and sets the
-``concrete`` keyword argument to ``True``::
-
-    class Person(Base):
-        __tablename__ = 'people'
-        id = Column(Integer, primary_key=True)
-        name = Column(String(50))
-
-    class Engineer(Person):
-        __tablename__ = 'engineers'
-        __mapper_args__ = {'concrete':True}
-        id = Column(Integer, primary_key=True)
-        primary_language = Column(String(50))
-        name = Column(String(50))
-
-Usage of an abstract base class is a little less straightforward as it
-requires usage of :func:`~sqlalchemy.orm.util.polymorphic_union`,
-which needs to be created with the :class:`.Table` objects
-before the class is built::
-
-    engineers = Table('engineers', Base.metadata,
-                    Column('id', Integer, primary_key=True),
-                    Column('name', String(50)),
-                    Column('primary_language', String(50))
-                )
-    managers = Table('managers', Base.metadata,
-                    Column('id', Integer, primary_key=True),
-                    Column('name', String(50)),
-                    Column('golf_swing', String(50))
-                )
-
-    punion = polymorphic_union({
-        'engineer':engineers,
-        'manager':managers
-    }, 'type', 'punion')
-
-    class Person(Base):
-        __table__ = punion
-        __mapper_args__ = {'polymorphic_on':punion.c.type}
-
-    class Engineer(Person):
-        __table__ = engineers
-        __mapper_args__ = {'polymorphic_identity':'engineer', 'concrete':True}
-
-    class Manager(Person):
-        __table__ = managers
-        __mapper_args__ = {'polymorphic_identity':'manager', 'concrete':True}
-
-.. _declarative_concrete_helpers:
-
-Using the Concrete Helpers
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Helper classes provides a simpler pattern for concrete inheritance.
-With these objects, the ``__declare_first__`` helper is used to configure the
-"polymorphic" loader for the mapper after all subclasses have been declared.
-
-.. versionadded:: 0.7.3
-
-An abstract base can be declared using the
-:class:`.AbstractConcreteBase` class::
-
-    from sqlalchemy.ext.declarative import AbstractConcreteBase
-
-    class Employee(AbstractConcreteBase, Base):
-        pass
-
-To have a concrete ``employee`` table, use :class:`.ConcreteBase` instead::
-
-    from sqlalchemy.ext.declarative import ConcreteBase
-
-    class Employee(ConcreteBase, Base):
-        __tablename__ = 'employee'
-        employee_id = Column(Integer, primary_key=True)
-        name = Column(String(50))
-        __mapper_args__ = {
-                        'polymorphic_identity':'employee',
-                        'concrete':True}
-
-
-Either ``Employee`` base can be used in the normal fashion::
-
-    class Manager(Employee):
-        __tablename__ = 'manager'
-        employee_id = Column(Integer, primary_key=True)
-        name = Column(String(50))
-        manager_data = Column(String(40))
-        __mapper_args__ = {
-                        'polymorphic_identity':'manager',
-                        'concrete':True}
-
-    class Engineer(Employee):
-        __tablename__ = 'engineer'
-        employee_id = Column(Integer, primary_key=True)
-        name = Column(String(50))
-        engineer_info = Column(String(40))
-        __mapper_args__ = {'polymorphic_identity':'engineer',
-                        'concrete':True}
-
-
-The :class:`.AbstractConcreteBase` class is itself mapped, and can be
-used as a target of relationships::
-
-    class Company(Base):
-        __tablename__ = 'company'
-
-        id = Column(Integer, primary_key=True)
-        employees = relationship("Employee",
-                        primaryjoin="Company.id == Employee.company_id")
-
-
-.. versionchanged:: 0.9.3 Support for use of :class:`.AbstractConcreteBase`
-   as the target of a :func:`.relationship` has been improved.
-
-It can also be queried directly::
-
-    for employee in session.query(Employee).filter(Employee.name == 'qbert'):
-        print(employee)
-
-
-.. _declarative_mixins:
-
-Mixin and Custom Base Classes
-==============================
-
-A common need when using :mod:`~sqlalchemy.ext.declarative` is to
-share some functionality, such as a set of common columns, some common
-table options, or other mapped properties, across many
-classes.  The standard Python idioms for this is to have the classes
-inherit from a base which includes these common features.
-
-When using :mod:`~sqlalchemy.ext.declarative`, this idiom is allowed
-via the usage of a custom declarative base class, as well as a "mixin" class
-which is inherited from in addition to the primary base.  Declarative
-includes several helper features to make this work in terms of how
-mappings are declared.   An example of some commonly mixed-in
-idioms is below::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class MyMixin(object):
-
-        @declared_attr
-        def __tablename__(cls):
-            return cls.__name__.lower()
-
-        __table_args__ = {'mysql_engine': 'InnoDB'}
-        __mapper_args__= {'always_refresh': True}
-
-        id =  Column(Integer, primary_key=True)
-
-    class MyModel(MyMixin, Base):
-        name = Column(String(1000))
-
-Where above, the class ``MyModel`` will contain an "id" column
-as the primary key, a ``__tablename__`` attribute that derives
-from the name of the class itself, as well as ``__table_args__``
-and ``__mapper_args__`` defined by the ``MyMixin`` mixin class.
-
-There's no fixed convention over whether ``MyMixin`` precedes
-``Base`` or not.  Normal Python method resolution rules apply, and
-the above example would work just as well with::
-
-    class MyModel(Base, MyMixin):
-        name = Column(String(1000))
-
-This works because ``Base`` here doesn't define any of the
-variables that ``MyMixin`` defines, i.e. ``__tablename__``,
-``__table_args__``, ``id``, etc.   If the ``Base`` did define
-an attribute of the same name, the class placed first in the
-inherits list would determine which attribute is used on the
-newly defined class.
-
-Augmenting the Base
-~~~~~~~~~~~~~~~~~~~
-
-In addition to using a pure mixin, most of the techniques in this
-section can also be applied to the base class itself, for patterns that
-should apply to all classes derived from a particular base.  This is achieved
-using the ``cls`` argument of the :func:`.declarative_base` function::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class Base(object):
-        @declared_attr
-        def __tablename__(cls):
-            return cls.__name__.lower()
-
-        __table_args__ = {'mysql_engine': 'InnoDB'}
-
-        id =  Column(Integer, primary_key=True)
-
-    from sqlalchemy.ext.declarative import declarative_base
-
-    Base = declarative_base(cls=Base)
-
-    class MyModel(Base):
-        name = Column(String(1000))
-
-Where above, ``MyModel`` and all other classes that derive from ``Base`` will
-have a table name derived from the class name, an ``id`` primary key column,
-as well as the "InnoDB" engine for MySQL.
-
-Mixing in Columns
-~~~~~~~~~~~~~~~~~
-
-The most basic way to specify a column on a mixin is by simple
-declaration::
-
-    class TimestampMixin(object):
-        created_at = Column(DateTime, default=func.now())
-
-    class MyModel(TimestampMixin, Base):
-        __tablename__ = 'test'
-
-        id =  Column(Integer, primary_key=True)
-        name = Column(String(1000))
-
-Where above, all declarative classes that include ``TimestampMixin``
-will also have a column ``created_at`` that applies a timestamp to
-all row insertions.
-
-Those familiar with the SQLAlchemy expression language know that
-the object identity of clause elements defines their role in a schema.
-Two ``Table`` objects ``a`` and ``b`` may both have a column called
-``id``, but the way these are differentiated is that ``a.c.id``
-and ``b.c.id`` are two distinct Python objects, referencing their
-parent tables ``a`` and ``b`` respectively.
-
-In the case of the mixin column, it seems that only one
-:class:`.Column` object is explicitly created, yet the ultimate
-``created_at`` column above must exist as a distinct Python object
-for each separate destination class.  To accomplish this, the declarative
-extension creates a **copy** of each :class:`.Column` object encountered on
-a class that is detected as a mixin.
-
-This copy mechanism is limited to simple columns that have no foreign
-keys, as a :class:`.ForeignKey` itself contains references to columns
-which can't be properly recreated at this level.  For columns that
-have foreign keys, as well as for the variety of mapper-level constructs
-that require destination-explicit context, the
-:class:`~.declared_attr` decorator is provided so that
-patterns common to many classes can be defined as callables::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class ReferenceAddressMixin(object):
-        @declared_attr
-        def address_id(cls):
-            return Column(Integer, ForeignKey('address.id'))
-
-    class User(ReferenceAddressMixin, Base):
-        __tablename__ = 'user'
-        id = Column(Integer, primary_key=True)
-
-Where above, the ``address_id`` class-level callable is executed at the
-point at which the ``User`` class is constructed, and the declarative
-extension can use the resulting :class:`.Column` object as returned by
-the method without the need to copy it.
-
-.. versionchanged:: > 0.6.5
-    Rename 0.6.5 ``sqlalchemy.util.classproperty``
-    into :class:`~.declared_attr`.
-
-Columns generated by :class:`~.declared_attr` can also be
-referenced by ``__mapper_args__`` to a limited degree, currently
-by ``polymorphic_on`` and ``version_id_col``, by specifying the
-classdecorator itself into the dictionary - the declarative extension
-will resolve them at class construction time::
-
-    class MyMixin:
-        @declared_attr
-        def type_(cls):
-            return Column(String(50))
-
-        __mapper_args__= {'polymorphic_on':type_}
-
-    class MyModel(MyMixin, Base):
-        __tablename__='test'
-        id =  Column(Integer, primary_key=True)
-
-
-
-Mixing in Relationships
-~~~~~~~~~~~~~~~~~~~~~~~
-
-Relationships created by :func:`~sqlalchemy.orm.relationship` are provided
-with declarative mixin classes exclusively using the
-:class:`.declared_attr` approach, eliminating any ambiguity
-which could arise when copying a relationship and its possibly column-bound
-contents. Below is an example which combines a foreign key column and a
-relationship so that two classes ``Foo`` and ``Bar`` can both be configured to
-reference a common target class via many-to-one::
-
-    class RefTargetMixin(object):
-        @declared_attr
-        def target_id(cls):
-            return Column('target_id', ForeignKey('target.id'))
-
-        @declared_attr
-        def target(cls):
-            return relationship("Target")
-
-    class Foo(RefTargetMixin, Base):
-        __tablename__ = 'foo'
-        id = Column(Integer, primary_key=True)
-
-    class Bar(RefTargetMixin, Base):
-        __tablename__ = 'bar'
-        id = Column(Integer, primary_key=True)
-
-    class Target(Base):
-        __tablename__ = 'target'
-        id = Column(Integer, primary_key=True)
-
-Using Advanced Relationship Arguments (e.g. ``primaryjoin``, etc.)
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-:func:`~sqlalchemy.orm.relationship` definitions which require explicit
-primaryjoin, order_by etc. expressions should in all but the most
-simplistic cases use **late bound** forms
-for these arguments, meaning, using either the string form or a lambda.
-The reason for this is that the related :class:`.Column` objects which are to
-be configured using ``@declared_attr`` are not available to another
-``@declared_attr`` attribute; while the methods will work and return new
-:class:`.Column` objects, those are not the :class:`.Column` objects that
-Declarative will be using as it calls the methods on its own, thus using
-*different* :class:`.Column` objects.
-
-The canonical example is the primaryjoin condition that depends upon
-another mixed-in column::
-
-    class RefTargetMixin(object):
-        @declared_attr
-        def target_id(cls):
-            return Column('target_id', ForeignKey('target.id'))
-
-        @declared_attr
-        def target(cls):
-            return relationship(Target,
-                primaryjoin=Target.id==cls.target_id   # this is *incorrect*
-            )
-
-Mapping a class using the above mixin, we will get an error like::
-
-    sqlalchemy.exc.InvalidRequestError: this ForeignKey's parent column is not
-    yet associated with a Table.
-
-This is because the ``target_id`` :class:`.Column` we've called upon in our ``target()``
-method is not the same :class:`.Column` that declarative is actually going to map
-to our table.
-
-The condition above is resolved using a lambda::
-
-    class RefTargetMixin(object):
-        @declared_attr
-        def target_id(cls):
-            return Column('target_id', ForeignKey('target.id'))
-
-        @declared_attr
-        def target(cls):
-            return relationship(Target,
-                primaryjoin=lambda: Target.id==cls.target_id
-            )
-
-or alternatively, the string form (which ultmately generates a lambda)::
-
-    class RefTargetMixin(object):
-        @declared_attr
-        def target_id(cls):
-            return Column('target_id', ForeignKey('target.id'))
-
-        @declared_attr
-        def target(cls):
-            return relationship("Target",
-                primaryjoin="Target.id==%s.target_id" % cls.__name__
-            )
-
-Mixing in deferred(), column_property(), and other MapperProperty classes
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Like :func:`~sqlalchemy.orm.relationship`, all
-:class:`~sqlalchemy.orm.interfaces.MapperProperty` subclasses such as
-:func:`~sqlalchemy.orm.deferred`, :func:`~sqlalchemy.orm.column_property`,
-etc. ultimately involve references to columns, and therefore, when
-used with declarative mixins, have the :class:`.declared_attr`
-requirement so that no reliance on copying is needed::
-
-    class SomethingMixin(object):
-
-        @declared_attr
-        def dprop(cls):
-            return deferred(Column(Integer))
-
-    class Something(SomethingMixin, Base):
-        __tablename__ = "something"
-
-Mixing in Association Proxy and Other Attributes
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Mixins can specify user-defined attributes as well as other extension
-units such as :func:`.association_proxy`.   The usage of
-:class:`.declared_attr` is required in those cases where the attribute must
-be tailored specifically to the target subclass.   An example is when
-constructing multiple :func:`.association_proxy` attributes which each
-target a different type of child object.  Below is an
-:func:`.association_proxy` / mixin example which provides a scalar list of
-string values to an implementing class::
-
-    from sqlalchemy import Column, Integer, ForeignKey, String
-    from sqlalchemy.orm import relationship
-    from sqlalchemy.ext.associationproxy import association_proxy
-    from sqlalchemy.ext.declarative import declarative_base, declared_attr
-
-    Base = declarative_base()
-
-    class HasStringCollection(object):
-        @declared_attr
-        def _strings(cls):
-            class StringAttribute(Base):
-                __tablename__ = cls.string_table_name
-                id = Column(Integer, primary_key=True)
-                value = Column(String(50), nullable=False)
-                parent_id = Column(Integer,
-                                ForeignKey('%s.id' % cls.__tablename__),
-                                nullable=False)
-                def __init__(self, value):
-                    self.value = value
-
-            return relationship(StringAttribute)
-
-        @declared_attr
-        def strings(cls):
-            return association_proxy('_strings', 'value')
-
-    class TypeA(HasStringCollection, Base):
-        __tablename__ = 'type_a'
-        string_table_name = 'type_a_strings'
-        id = Column(Integer(), primary_key=True)
-
-    class TypeB(HasStringCollection, Base):
-        __tablename__ = 'type_b'
-        string_table_name = 'type_b_strings'
-        id = Column(Integer(), primary_key=True)
-
-Above, the ``HasStringCollection`` mixin produces a :func:`.relationship`
-which refers to a newly generated class called ``StringAttribute``.  The
-``StringAttribute`` class is generated with it's own :class:`.Table`
-definition which is local to the parent class making usage of the
-``HasStringCollection`` mixin.  It also produces an :func:`.association_proxy`
-object which proxies references to the ``strings`` attribute onto the ``value``
-attribute of each ``StringAttribute`` instance.
-
-``TypeA`` or ``TypeB`` can be instantiated given the constructor
-argument ``strings``, a list of strings::
-
-    ta = TypeA(strings=['foo', 'bar'])
-    tb = TypeA(strings=['bat', 'bar'])
-
-This list will generate a collection
-of ``StringAttribute`` objects, which are persisted into a table that's
-local to either the ``type_a_strings`` or ``type_b_strings`` table::
-
-    >>> print ta._strings
-    [<__main__.StringAttribute object at 0x10151cd90>,
-        <__main__.StringAttribute object at 0x10151ce10>]
-
-When constructing the :func:`.association_proxy`, the
-:class:`.declared_attr` decorator must be used so that a distinct
-:func:`.association_proxy` object is created for each of the ``TypeA``
-and ``TypeB`` classes.
-
-.. versionadded:: 0.8 :class:`.declared_attr` is usable with non-mapped
-   attributes, including user-defined attributes as well as
-   :func:`.association_proxy`.
-
-
-Controlling table inheritance with mixins
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The ``__tablename__`` attribute in conjunction with the hierarchy of
-classes involved in a declarative mixin scenario controls what type of
-table inheritance, if any,
-is configured by the declarative extension.
-
-If the ``__tablename__`` is computed by a mixin, you may need to
-control which classes get the computed attribute in order to get the
-type of table inheritance you require.
-
-For example, if you had a mixin that computes ``__tablename__`` but
-where you wanted to use that mixin in a single table inheritance
-hierarchy, you can explicitly specify ``__tablename__`` as ``None`` to
-indicate that the class should not have a table mapped::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class Tablename:
-        @declared_attr
-        def __tablename__(cls):
-            return cls.__name__.lower()
-
-    class Person(Tablename, Base):
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        __tablename__ = None
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-        primary_language = Column(String(50))
-
-Alternatively, you can make the mixin intelligent enough to only
-return a ``__tablename__`` in the event that no table is already
-mapped in the inheritance hierarchy. To help with this, a
-:func:`~sqlalchemy.ext.declarative.has_inherited_table` helper
-function is provided that returns ``True`` if a parent class already
-has a mapped table.
-
-As an example, here's a mixin that will only allow single table
-inheritance::
-
-    from sqlalchemy.ext.declarative import declared_attr
-    from sqlalchemy.ext.declarative import has_inherited_table
-
-    class Tablename(object):
-        @declared_attr
-        def __tablename__(cls):
-            if has_inherited_table(cls):
-                return None
-            return cls.__name__.lower()
-
-    class Person(Tablename, Base):
-        id = Column(Integer, primary_key=True)
-        discriminator = Column('type', String(50))
-        __mapper_args__ = {'polymorphic_on': discriminator}
-
-    class Engineer(Person):
-        primary_language = Column(String(50))
-        __mapper_args__ = {'polymorphic_identity': 'engineer'}
-
-
-Combining Table/Mapper Arguments from Multiple Mixins
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-In the case of ``__table_args__`` or ``__mapper_args__``
-specified with declarative mixins, you may want to combine
-some parameters from several mixins with those you wish to
-define on the class iteself. The
-:class:`.declared_attr` decorator can be used
-here to create user-defined collation routines that pull
-from multiple collections::
-
-    from sqlalchemy.ext.declarative import declared_attr
-
-    class MySQLSettings(object):
-        __table_args__ = {'mysql_engine':'InnoDB'}
-
-    class MyOtherMixin(object):
-        __table_args__ = {'info':'foo'}
-
-    class MyModel(MySQLSettings, MyOtherMixin, Base):
-        __tablename__='my_model'
-
-        @declared_attr
-        def __table_args__(cls):
-            args = dict()
-            args.update(MySQLSettings.__table_args__)
-            args.update(MyOtherMixin.__table_args__)
-            return args
-
-        id =  Column(Integer, primary_key=True)
-
-Creating Indexes with Mixins
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-To define a named, potentially multicolumn :class:`.Index` that applies to all
-tables derived from a mixin, use the "inline" form of :class:`.Index` and
-establish it as part of ``__table_args__``::
-
-    class MyMixin(object):
-        a =  Column(Integer)
-        b =  Column(Integer)
-
-        @declared_attr
-        def __table_args__(cls):
-            return (Index('test_idx_%s' % cls.__tablename__, 'a', 'b'),)
-
-    class MyModel(MyMixin, Base):
-        __tablename__ = 'atable'
-        c =  Column(Integer,primary_key=True)
-
-Special Directives
-==================
-
-``__declare_last__()``
-~~~~~~~~~~~~~~~~~~~~~~
-
-The ``__declare_last__()`` hook allows definition of
-a class level function that is automatically called by the
-:meth:`.MapperEvents.after_configured` event, which occurs after mappings are
-assumed to be completed and the 'configure' step has finished::
-
-    class MyClass(Base):
-        @classmethod
-        def __declare_last__(cls):
-            ""
-            # do something with mappings
-
-.. versionadded:: 0.7.3
-
-``__declare_first__()``
-~~~~~~~~~~~~~~~~~~~~~~~
-
-Like ``__declare_last__()``, but is called at the beginning of mapper configuration
-via the :meth:`.MapperEvents.before_configured` event::
-
-    class MyClass(Base):
-        @classmethod
-        def __declare_first__(cls):
-            ""
-            # do something before mappings are configured
-
-.. versionadded:: 0.9.3
-
-.. _declarative_abstract:
-
-``__abstract__``
-~~~~~~~~~~~~~~~~~~~
-
-``__abstract__`` causes declarative to skip the production
-of a table or mapper for the class entirely.  A class can be added within a
-hierarchy in the same way as mixin (see :ref:`declarative_mixins`), allowing
-subclasses to extend just from the special class::
-
-    class SomeAbstractBase(Base):
-        __abstract__ = True
-
-        def some_helpful_method(self):
-            ""
-
-        @declared_attr
-        def __mapper_args__(cls):
-            return {"helpful mapper arguments":True}
-
-    class MyMappedClass(SomeAbstractBase):
-        ""
-
-One possible use of ``__abstract__`` is to use a distinct
-:class:`.MetaData` for different bases::
-
-    Base = declarative_base()
-
-    class DefaultBase(Base):
-        __abstract__ = True
-        metadata = MetaData()
-
-    class OtherBase(Base):
-        __abstract__ = True
-        metadata = MetaData()
-
-Above, classes which inherit from ``DefaultBase`` will use one
-:class:`.MetaData` as the registry of tables, and those which inherit from
-``OtherBase`` will use a different one. The tables themselves can then be
-created perhaps within distinct databases::
-
-    DefaultBase.metadata.create_all(some_engine)
-    OtherBase.metadata_create_all(some_other_engine)
-
-.. versionadded:: 0.7.3
-
-Class Constructor
-=================
-
-As a convenience feature, the :func:`declarative_base` sets a default
-constructor on classes which takes keyword arguments, and assigns them
-to the named attributes::
-
-    e = Engineer(primary_language='python')
-
-Sessions
-========
-
-Note that ``declarative`` does nothing special with sessions, and is
-only intended as an easier way to configure mappers and
-:class:`~sqlalchemy.schema.Table` objects.  A typical application
-setup using :class:`~sqlalchemy.orm.scoping.scoped_session` might look like::
-
-    engine = create_engine('postgresql://scott:tiger@localhost/test')
-    Session = scoped_session(sessionmaker(autocommit=False,
-                                          autoflush=False,
-                                          bind=engine))
-    Base = declarative_base()
-
-Mapped instances then make usage of
-:class:`~sqlalchemy.orm.session.Session` in the usual way.

-class DeferredReflection(object):
-    """A helper class for construction of mappings based on
-    a deferred reflection step.
-
-    Normally, declarative can be used with reflection by
-    setting a :class:`.Table` object using autoload=True
-    as the ``__table__`` attribute on a declarative class.
-    The caveat is that the :class:`.Table` must be fully
-    reflected, or at the very least have a primary key column,
-    at the point at which a normal declarative mapping is
-    constructed, meaning the :class:`.Engine` must be available
-    at class declaration time.
-
-    The :class:`.DeferredReflection` mixin moves the construction
-    of mappers to be at a later point, after a specific
-    method is called which first reflects all :class:`.Table`
-    objects created so far.   Classes can define it as such::
-
-        from sqlalchemy.ext.declarative import declarative_base
-        from sqlalchemy.ext.declarative import DeferredReflection
-        Base = declarative_base()
-
-        class MyClass(DeferredReflection, Base):
-            __tablename__ = 'mytable'
-
-    Above, ``MyClass`` is not yet mapped.   After a series of
-    classes have been defined in the above fashion, all tables
-    can be reflected and mappings created using
-    :meth:`.prepare`::
-
-        engine = create_engine("someengine://...")
-        DeferredReflection.prepare(engine)
-
-    The :class:`.DeferredReflection` mixin can be applied to individual
-    classes, used as the base for the declarative base itself,
-    or used in a custom abstract class.   Using an abstract base
-    allows that only a subset of classes to be prepared for a
-    particular prepare step, which is necessary for applications
-    that use more than one engine.  For example, if an application
-    has two engines, you might use two bases, and prepare each
-    separately, e.g.::
-
-        class ReflectedOne(DeferredReflection, Base):
-            __abstract__ = True
-
-        class ReflectedTwo(DeferredReflection, Base):

-
-        class YetAnotherClass(ReflectedTwo):
-            __tablename__ = 'yetanothertable'
-
-        # ... etc.
-
-    Above, the class hierarchies for ``ReflectedOne`` and
-    ``ReflectedTwo`` can be configured separately::
-
-        ReflectedOne.prepare(engine_one)
-        ReflectedTwo.prepare(engine_two)

-"""Define attributes on ORM-mapped classes that have "hybrid" behavior.
-
-"hybrid" means the attribute has distinct behaviors defined at the
-class level and at the instance level.
-
-The :mod:`~sqlalchemy.ext.hybrid` extension provides a special form of
-method decorator, is around 50 lines of code and has almost no
-dependencies on the rest of SQLAlchemy.  It can, in theory, work with
-any descriptor-based expression system.
-
-Consider a mapping ``Interval``, representing integer ``start`` and ``end``
-values. We can define higher level functions on mapped classes that produce
-SQL expressions at the class level, and Python expression evaluation at the
-instance level.  Below, each function decorated with :class:`.hybrid_method` or
-:class:`.hybrid_property` may receive ``self`` as an instance of the class, or
-as the class itself::
-
-    from sqlalchemy import Column, Integer
-    from sqlalchemy.ext.declarative import declarative_base
-    from sqlalchemy.orm import Session, aliased
-    from sqlalchemy.ext.hybrid import hybrid_property, hybrid_method
-
-    Base = declarative_base()
-
-    class Interval(Base):
-        __tablename__ = 'interval'
-
-        id = Column(Integer, primary_key=True)
-        start = Column(Integer, nullable=False)
-        end = Column(Integer, nullable=False)
-
-        def __init__(self, start, end):
-            self.start = start
-            self.end = end
-
-        @hybrid_property
-        def length(self):
-            return self.end - self.start
-
-        @hybrid_method
-        def contains(self,point):
-            return (self.start <= point) & (point < self.end)
-
-        @hybrid_method
-        def intersects(self, other):
-            return self.contains(other.start) | self.contains(other.end)
-
-Above, the ``length`` property returns the difference between the
-``end`` and ``start`` attributes.  With an instance of ``Interval``,
-this subtraction occurs in Python, using normal Python descriptor
-mechanics::
-
-    >>> i1 = Interval(5, 10)
-    >>> i1.length
-    5
-
-When dealing with the ``Interval`` class itself, the :class:`.hybrid_property`
-descriptor evaluates the function body given the ``Interval`` class as
-the argument, which when evaluated with SQLAlchemy expression mechanics
-returns a new SQL expression::
-
-    >>> print Interval.length
-    interval."end" - interval.start
-
-    >>> print Session().query(Interval).filter(Interval.length > 10)
-    SELECT interval.id AS interval_id, interval.start AS interval_start,
-    interval."end" AS interval_end
-    FROM interval
-    WHERE interval."end" - interval.start > :param_1
-
-ORM methods such as :meth:`~.Query.filter_by` generally use ``getattr()`` to
-locate attributes, so can also be used with hybrid attributes::
-
-    >>> print Session().query(Interval).filter_by(length=5)
-    SELECT interval.id AS interval_id, interval.start AS interval_start,
-    interval."end" AS interval_end
-    FROM interval
-    WHERE interval."end" - interval.start = :param_1
-
-The ``Interval`` class example also illustrates two methods,
-``contains()`` and ``intersects()``, decorated with
-:class:`.hybrid_method`. This decorator applies the same idea to
-methods that :class:`.hybrid_property` applies to attributes.   The
-methods return boolean values, and take advantage of the Python ``|``
-and ``&`` bitwise operators to produce equivalent instance-level and
-SQL expression-level boolean behavior::
-
-    >>> i1.contains(6)
-    True
-    >>> i1.contains(15)
-    False
-    >>> i1.intersects(Interval(7, 18))
-    True
-    >>> i1.intersects(Interval(25, 29))
-    False
-
-    >>> print Session().query(Interval).filter(Interval.contains(15))
-    SELECT interval.id AS interval_id, interval.start AS interval_start,
-    interval."end" AS interval_end
-    FROM interval
-    WHERE interval.start <= :start_1 AND interval."end" > :end_1
-
-    >>> ia = aliased(Interval)
-    >>> print Session().query(Interval, ia).filter(Interval.intersects(ia))
-    SELECT interval.id AS interval_id, interval.start AS interval_start,
-    interval."end" AS interval_end, interval_1.id AS interval_1_id,
-    interval_1.start AS interval_1_start, interval_1."end" AS interval_1_end
-    FROM interval, interval AS interval_1
-    WHERE interval.start <= interval_1.start
-        AND interval."end" > interval_1.start
-        OR interval.start <= interval_1."end"
-        AND interval."end" > interval_1."end"
-
-Defining Expression Behavior Distinct from Attribute Behavior
---------------------------------------------------------------
-
-Our usage of the ``&`` and ``|`` bitwise operators above was
-fortunate, considering our functions operated on two boolean values to
-return a new one.   In many cases, the construction of an in-Python
-function and a SQLAlchemy SQL expression have enough differences that
-two separate Python expressions should be defined.  The
-:mod:`~sqlalchemy.ext.hybrid` decorators define the
-:meth:`.hybrid_property.expression` modifier for this purpose.   As an
-example we'll define the radius of the interval, which requires the
-usage of the absolute value function::
-
-    from sqlalchemy import func
-
-    class Interval(object):
-        # ...
-
-        @hybrid_property
-        def radius(self):
-            return abs(self.length) / 2
-
-        @radius.expression
-        def radius(cls):
-            return func.abs(cls.length) / 2
-
-Above the Python function ``abs()`` is used for instance-level
-operations, the SQL function ``ABS()`` is used via the :attr:`.func`
-object for class-level expressions::
-
-    >>> i1.radius
-    2
-
-    >>> print Session().query(Interval).filter(Interval.radius > 5)
-    SELECT interval.id AS interval_id, interval.start AS interval_start,
-        interval."end" AS interval_end
-    FROM interval
-    WHERE abs(interval."end" - interval.start) / :abs_1 > :param_1
-
-Defining Setters
-----------------
-
-Hybrid properties can also define setter methods.  If we wanted
-``length`` above, when set, to modify the endpoint value::
-
-    class Interval(object):
-        # ...
-
-        @hybrid_property
-        def length(self):
-            return self.end - self.start
-
-        @length.setter
-        def length(self, value):
-            self.end = self.start + value
-
-The ``length(self, value)`` method is now called upon set::
-
-    >>> i1 = Interval(5, 10)
-    >>> i1.length
-    5
-    >>> i1.length = 12
-    >>> i1.end
-    17
-
-Working with Relationships
---------------------------
-
-There's no essential difference when creating hybrids that work with
-related objects as opposed to column-based data. The need for distinct
-expressions tends to be greater.  Two variants of we'll illustrate
-are the "join-dependent" hybrid, and the "correlated subquery" hybrid.
-
-Join-Dependent Relationship Hybrid
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Consider the following declarative
-mapping which relates a ``User`` to a ``SavingsAccount``::
-
-    from sqlalchemy import Column, Integer, ForeignKey, Numeric, String
-    from sqlalchemy.orm import relationship
-    from sqlalchemy.ext.declarative import declarative_base
-    from sqlalchemy.ext.hybrid import hybrid_property
-
-    Base = declarative_base()
-
-    class SavingsAccount(Base):
-        __tablename__ = 'account'
-        id = Column(Integer, primary_key=True)
-        user_id = Column(Integer, ForeignKey('user.id'), nullable=False)
-        balance = Column(Numeric(15, 5))
-
-    class User(Base):
-        __tablename__ = 'user'
-        id = Column(Integer, primary_key=True)
-        name = Column(String(100), nullable=False)
-
-        accounts = relationship("SavingsAccount", backref="owner")
-
-        @hybrid_property
-        def balance(self):
-            if self.accounts:
-                return self.accounts[0].balance
-            else:
-                return None
-
-        @balance.setter
-        def balance(self, value):
-            if not self.accounts:
-                account = Account(owner=self)
-            else:
-                account = self.accounts[0]
-            account.balance = value
-
-        @balance.expression
-        def balance(cls):
-            return SavingsAccount.balance
-
-The above hybrid property ``balance`` works with the first
-``SavingsAccount`` entry in the list of accounts for this user.   The
-in-Python getter/setter methods can treat ``accounts`` as a Python
-list available on ``self``.
-
-However, at the expression level, it's expected that the ``User`` class will
-be used in an appropriate context such that an appropriate join to
-``SavingsAccount`` will be present::
-
-    >>> print Session().query(User, User.balance).\\
-    ...     join(User.accounts).filter(User.balance > 5000)
-    SELECT "user".id AS user_id, "user".name AS user_name,
-    account.balance AS account_balance
-    FROM "user" JOIN account ON "user".id = account.user_id
-    WHERE account.balance > :balance_1
-
-Note however, that while the instance level accessors need to worry
-about whether ``self.accounts`` is even present, this issue expresses
-itself differently at the SQL expression level, where we basically
-would use an outer join::
-
-    >>> from sqlalchemy import or_
-    >>> print (Session().query(User, User.balance).outerjoin(User.accounts).
-    ...         filter(or_(User.balance < 5000, User.balance == None)))
-    SELECT "user".id AS user_id, "user".name AS user_name,
-    account.balance AS account_balance
-    FROM "user" LEFT OUTER JOIN account ON "user".id = account.user_id
-    WHERE account.balance <  :balance_1 OR account.balance IS NULL
-
-Correlated Subquery Relationship Hybrid
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-We can, of course, forego being dependent on the enclosing query's usage
-of joins in favor of the correlated subquery, which can portably be packed
-into a single column expression. A correlated subquery is more portable, but
-often performs more poorly at the SQL level. Using the same technique
-illustrated at :ref:`mapper_column_property_sql_expressions`,
-we can adjust our ``SavingsAccount`` example to aggregate the balances for
-*all* accounts, and use a correlated subquery for the column expression::
-
-    from sqlalchemy import Column, Integer, ForeignKey, Numeric, String
-    from sqlalchemy.orm import relationship
-    from sqlalchemy.ext.declarative import declarative_base
-    from sqlalchemy.ext.hybrid import hybrid_property
-    from sqlalchemy import select, func
-
-    Base = declarative_base()
-
-    class SavingsAccount(Base):
-        __tablename__ = 'account'
-        id = Column(Integer, primary_key=True)
-        user_id = Column(Integer, ForeignKey('user.id'), nullable=False)
-        balance = Column(Numeric(15, 5))
-
-    class User(Base):
-        __tablename__ = 'user'
-        id = Column(Integer, primary_key=True)
-        name = Column(String(100), nullable=False)
-
-        accounts = relationship("SavingsAccount", backref="owner")
-
-        @hybrid_property
-        def balance(self):
-            return sum(acc.balance for acc in self.accounts)
-
-        @balance.expression
-        def balance(cls):
-            return select([func.sum(SavingsAccount.balance)]).\\
-                    where(SavingsAccount.user_id==cls.id).\\
-                    label('total_balance')
-
-The above recipe will give us the ``balance`` column which renders
-a correlated SELECT::
-
-    >>> print s.query(User).filter(User.balance > 400)
-    SELECT "user".id AS user_id, "user".name AS user_name
-    FROM "user"
-    WHERE (SELECT sum(account.balance) AS sum_1
-    FROM account
-    WHERE account.user_id = "user".id) > :param_1
-
-.. _hybrid_custom_comparators:
-
-Building Custom Comparators
----------------------------
-
-The hybrid property also includes a helper that allows construction of
-custom comparators. A comparator object allows one to customize the
-behavior of each SQLAlchemy expression operator individually.  They
-are useful when creating custom types that have some highly
-idiosyncratic behavior on the SQL side.
-
-The example class below allows case-insensitive comparisons on the attribute
-named ``word_insensitive``::
-
-    from sqlalchemy.ext.hybrid import Comparator, hybrid_property
-    from sqlalchemy import func, Column, Integer, String
-    from sqlalchemy.orm import Session
-    from sqlalchemy.ext.declarative import declarative_base
-
-    Base = declarative_base()
-
-    class CaseInsensitiveComparator(Comparator):
-        def __eq__(self, other):
-            return func.lower(self.__clause_element__()) == func.lower(other)
-
-    class SearchWord(Base):
-        __tablename__ = 'searchword'
-        id = Column(Integer, primary_key=True)
-        word = Column(String(255), nullable=False)
-
-        @hybrid_property
-        def word_insensitive(self):
-            return self.word.lower()
-
-        @word_insensitive.comparator
-        def word_insensitive(cls):
-            return CaseInsensitiveComparator(cls.word)
-
-Above, SQL expressions against ``word_insensitive`` will apply the ``LOWER()``
-SQL function to both sides::
-
-    >>> print Session().query(SearchWord).filter_by(word_insensitive="Trucks")
-    SELECT searchword.id AS searchword_id, searchword.word AS searchword_word
-    FROM searchword
-    WHERE lower(searchword.word) = lower(:lower_1)
-
-The ``CaseInsensitiveComparator`` above implements part of the
-:class:`.ColumnOperators` interface.   A "coercion" operation like
-lowercasing can be applied to all comparison operations (i.e. ``eq``,
-``lt``, ``gt``, etc.) using :meth:`.Operators.operate`::
-
-    class CaseInsensitiveComparator(Comparator):
-        def operate(self, op, other):
-            return op(func.lower(self.__clause_element__()), func.lower(other))
-
-Hybrid Value Objects
---------------------
-
-Note in our previous example, if we were to compare the
-``word_insensitive`` attribute of a ``SearchWord`` instance to a plain
-Python string, the plain Python string would not be coerced to lower
-case - the ``CaseInsensitiveComparator`` we built, being returned by
-``@word_insensitive.comparator``, only applies to the SQL side.
-
-A more comprehensive form of the custom comparator is to construct a
-*Hybrid Value Object*. This technique applies the target value or
-expression to a value object which is then returned by the accessor in
-all cases.   The value object allows control of all operations upon
-the value as well as how compared values are treated, both on the SQL
-expression side as well as the Python value side.   Replacing the
-previous ``CaseInsensitiveComparator`` class with a new
-``CaseInsensitiveWord`` class::
-
-    class CaseInsensitiveWord(Comparator):
-        "Hybrid value representing a lower case representation of a word."
-
-        def __init__(self, word):
-            if isinstance(word, basestring):
-                self.word = word.lower()
-            elif isinstance(word, CaseInsensitiveWord):
-                self.word = word.word
-            else:
-                self.word = func.lower(word)
-
-        def operate(self, op, other):
-            if not isinstance(other, CaseInsensitiveWord):
-                other = CaseInsensitiveWord(other)
-            return op(self.word, other.word)
-
-        def __clause_element__(self):
-            return self.word
-
-        def __str__(self):
-            return self.word
-
-        key = 'word'
-        "Label to apply to Query tuple results"
-
-Above, the ``CaseInsensitiveWord`` object represents ``self.word``,
-which may be a SQL function, or may be a Python native.   By
-overriding ``operate()`` and ``__clause_element__()`` to work in terms
-of ``self.word``, all comparison operations will work against the
-"converted" form of ``word``, whether it be SQL side or Python side.
-Our ``SearchWord`` class can now deliver the ``CaseInsensitiveWord``
-object unconditionally from a single hybrid call::
-
-    class SearchWord(Base):
-        __tablename__ = 'searchword'
-        id = Column(Integer, primary_key=True)
-        word = Column(String(255), nullable=False)
-
-        @hybrid_property
-        def word_insensitive(self):
-            return CaseInsensitiveWord(self.word)
-
-The ``word_insensitive`` attribute now has case-insensitive comparison
-behavior universally, including SQL expression vs. Python expression
-(note the Python value is converted to lower case on the Python side
-here)::
-
-    >>> print Session().query(SearchWord).filter_by(word_insensitive="Trucks")
-    SELECT searchword.id AS searchword_id, searchword.word AS searchword_word
-    FROM searchword
-    WHERE lower(searchword.word) = :lower_1
-
-SQL expression versus SQL expression::
-
-    >>> sw1 = aliased(SearchWord)
-    >>> sw2 = aliased(SearchWord)
-    >>> print Session().query(
-    ...                    sw1.word_insensitive,

-
-Building Transformers
-----------------------
-
-A *transformer* is an object which can receive a :class:`.Query`
-object and return a new one.   The :class:`.Query` object includes a
-method :meth:`.with_transformation` that returns a new :class:`.Query`
-transformed by the given function.
-
-We can combine this with the :class:`.Comparator` class to produce one type
-of recipe which can both set up the FROM clause of a query as well as assign
-filtering criterion.
-
-Consider a mapped class ``Node``, which assembles using adjacency list
-into a hierarchical tree pattern::
-
-    from sqlalchemy import Column, Integer, ForeignKey
-    from sqlalchemy.orm import relationship
-    from sqlalchemy.ext.declarative import declarative_base
-    Base = declarative_base()
-
-    class Node(Base):
-        __tablename__ = 'node'
-        id =Column(Integer, primary_key=True)
-        parent_id = Column(Integer, ForeignKey('node.id'))
-        parent = relationship("Node", remote_side=id)
-
-Suppose we wanted to add an accessor ``grandparent``.  This would
-return the ``parent`` of ``Node.parent``.  When we have an instance of
-``Node``, this is simple::
-
-    from sqlalchemy.ext.hybrid import hybrid_property
-
-    class Node(Base):
-        # ...
-
-        @hybrid_property
-        def grandparent(self):
-            return self.parent.parent
-
-For the expression, things are not so clear.   We'd need to construct
-a :class:`.Query` where we :meth:`~.Query.join` twice along
-``Node.parent`` to get to the ``grandparent``.   We can instead return
-a transforming callable that we'll combine with the
-:class:`.Comparator` class to receive any :class:`.Query` object, and
-return a new one that's joined to the ``Node.parent`` attribute and
-filtered based on the given criterion::
-
-    from sqlalchemy.ext.hybrid import Comparator
-
-    class GrandparentTransformer(Comparator):
-        def operate(self, op, other):
-            def transform(q):
-                cls = self.__clause_element__()
-                parent_alias = aliased(cls)
-                return q.join(parent_alias, cls.parent).\\
-                            filter(op(parent_alias.parent, other))
-            return transform
-
-    Base = declarative_base()
-
-    class Node(Base):
-        __tablename__ = 'node'
-        id =Column(Integer, primary_key=True)
-        parent_id = Column(Integer, ForeignKey('node.id'))
-        parent = relationship("Node", remote_side=id)
-
-        @hybrid_property
-        def grandparent(self):
-            return self.parent.parent
-
-        @grandparent.comparator
-        def grandparent(cls):
-            return GrandparentTransformer(cls)
-
-The ``GrandparentTransformer`` overrides the core
-:meth:`.Operators.operate` method at the base of the
-:class:`.Comparator` hierarchy to return a query-transforming
-callable, which then runs the given comparison operation in a
-particular context. Such as, in the example above, the ``operate``
-method is called, given the :attr:`.Operators.eq` callable as well as
-the right side of the comparison ``Node(id=5)``.  A function
-``transform`` is then returned which will transform a :class:`.Query`
-first to join to ``Node.parent``, then to compare ``parent_alias``
-using :attr:`.Operators.eq` against the left and right sides, passing
-into :class:`.Query.filter`:
-
-.. sourcecode:: pycon+sql
-
-    >>> from sqlalchemy.orm import Session
-    >>> session = Session()
-    {sql}>>> session.query(Node).\\
-    ...        with_transformation(Node.grandparent==Node(id=5)).\\
-    ...        all()
-    SELECT node.id AS node_id, node.parent_id AS node_parent_id
-    FROM node JOIN node AS node_1 ON node_1.id = node.parent_id
-    WHERE :param_1 = node_1.parent_id
-    {stop}
-
-We can modify the pattern to be more verbose but flexible by separating
-the "join" step from the "filter" step.  The tricky part here is ensuring
-that successive instances of ``GrandparentTransformer`` use the same
-:class:`.AliasedClass` object against ``Node``.  Below we use a simple
-memoizing approach that associates a ``GrandparentTransformer``
-with each class::
-
-    class Node(Base):
-
-        # ...
-
-        @grandparent.comparator
-        def grandparent(cls):
-            # memoize a GrandparentTransformer
-            # per class
-            if '_gp' not in cls.__dict__:
-                cls._gp = GrandparentTransformer(cls)
-            return cls._gp
-
-    class GrandparentTransformer(Comparator):
-
-        def __init__(self, cls):
-            self.parent_alias = aliased(cls)
-
-        @property
-        def join(self):
-            def go(q):
-                return q.join(self.parent_alias, Node.parent)
-            return go
-
-        def operate(self, op, other):
-            return op(self.parent_alias.parent, other)
-
-.. sourcecode:: pycon+sql
-
-    {sql}>>> session.query(Node).\\
-    ...            with_transformation(Node.grandparent.join).\\
-    ...            filter(Node.grandparent==Node(id=5))
-    SELECT node.id AS node_id, node.parent_id AS node_parent_id
-    FROM node JOIN node AS node_1 ON node_1.id = node.parent_id
-    WHERE :param_1 = node_1.parent_id
-    {stop}
-
-The "transformer" pattern is an experimental pattern that starts
-to make usage of some functional programming paradigms.
-While it's only recommended for advanced and/or patient developers,
-there's probably a whole lot of amazing things it can be used for.

-"""Provide support for tracking of in-place changes to scalar values,
-which are propagated into ORM change events on owning parent objects.

-   legacy approach to in-place mutations of scalar values; see
-   :ref:`07_migration_mutation_extension`.
-

-
-Establishing Mutability on Scalar Column Values
-===============================================
-
-A typical example of a "mutable" structure is a Python dictionary.
-Following the example introduced in :ref:`types_toplevel`, we
-begin with a custom type that marshals Python dictionaries into
-JSON strings before being persisted::
-
-    from sqlalchemy.types import TypeDecorator, VARCHAR
-    import json
-
-    class JSONEncodedDict(TypeDecorator):
-        "Represents an immutable structure as a json-encoded string."
-
-        impl = VARCHAR
-
-        def process_bind_param(self, value, dialect):
-            if value is not None:
-                value = json.dumps(value)
-            return value
-
-        def process_result_value(self, value, dialect):
-            if value is not None:
-                value = json.loads(value)
-            return value
-
-The usage of ``json`` is only for the purposes of example. The
-:mod:`sqlalchemy.ext.mutable` extension can be used
-with any type whose target Python type may be mutable, including
-:class:`.PickleType`, :class:`.postgresql.ARRAY`, etc.
-
-When using the :mod:`sqlalchemy.ext.mutable` extension, the value itself
-tracks all parents which reference it.  Below, we illustrate the a simple
-version of the :class:`.MutableDict` dictionary object, which applies
-the :class:`.Mutable` mixin to a plain Python dictionary::
-
-    from sqlalchemy.ext.mutable import Mutable
-
-    class MutableDict(Mutable, dict):
-        @classmethod
-        def coerce(cls, key, value):
-            "Convert plain dictionaries to MutableDict."
-
-            if not isinstance(value, MutableDict):
-                if isinstance(value, dict):
-                    return MutableDict(value)
-
-                # this call will raise ValueError
-                return Mutable.coerce(key, value)
-            else:
-                return value
-
-        def __setitem__(self, key, value):
-            "Detect dictionary set events and emit change events."
-
-            dict.__setitem__(self, key, value)
-            self.changed()
-
-        def __delitem__(self, key):
-            "Detect dictionary del events and emit change events."
-
-            dict.__delitem__(self, key)
-            self.changed()
-
-The above dictionary class takes the approach of subclassing the Python
-built-in ``dict`` to produce a dict
-subclass which routes all mutation events through ``__setitem__``.  There are
-variants on this approach, such as subclassing ``UserDict.UserDict`` or
-``collections.MutableMapping``; the part that's important to this example is
-that the :meth:`.Mutable.changed` method is called whenever an in-place
-change to the datastructure takes place.
-
-We also redefine the :meth:`.Mutable.coerce` method which will be used to
-convert any values that are not instances of ``MutableDict``, such
-as the plain dictionaries returned by the ``json`` module, into the
-appropriate type.  Defining this method is optional; we could just as well
-created our ``JSONEncodedDict`` such that it always returns an instance
-of ``MutableDict``, and additionally ensured that all calling code
-uses ``MutableDict`` explicitly.  When :meth:`.Mutable.coerce` is not
-overridden, any values applied to a parent object which are not instances
-of the mutable type will raise a ``ValueError``.
-
-Our new ``MutableDict`` type offers a class method
-:meth:`~.Mutable.as_mutable` which we can use within column metadata
-to associate with types. This method grabs the given type object or
-class and associates a listener that will detect all future mappings
-of this type, applying event listening instrumentation to the mapped
-attribute. Such as, with classical table metadata::
-
-    from sqlalchemy import Table, Column, Integer
-
-    my_data = Table('my_data', metadata,
-        Column('id', Integer, primary_key=True),
-        Column('data', MutableDict.as_mutable(JSONEncodedDict))
-    )
-
-Above, :meth:`~.Mutable.as_mutable` returns an instance of ``JSONEncodedDict``
-(if the type object was not an instance already), which will intercept any
-attributes which are mapped against this type.  Below we establish a simple
-mapping against the ``my_data`` table::
-
-    from sqlalchemy import mapper
-
-    class MyDataClass(object):
-        pass
-
-    # associates mutation listeners with MyDataClass.data
-    mapper(MyDataClass, my_data)
-
-The ``MyDataClass.data`` member will now be notified of in place changes
-to its value.
-
-There's no difference in usage when using declarative::
-
-    from sqlalchemy.ext.declarative import declarative_base
-
-    Base = declarative_base()
-
-    class MyDataClass(Base):
-        __tablename__ = 'my_data'
-        id = Column(Integer, primary_key=True)
-        data = Column(MutableDict.as_mutable(JSONEncodedDict))
-
-Any in-place changes to the ``MyDataClass.data`` member
-will flag the attribute as "dirty" on the parent object::
-
-    >>> from sqlalchemy.orm import Session
-
-    >>> sess = Session()
-    >>> m1 = MyDataClass(data={'value1':'foo'})
-    >>> sess.add(m1)
-    >>> sess.commit()
-
-    >>> m1.data['value1'] = 'bar'
-    >>> assert m1 in sess.dirty
-    True
-
-The ``MutableDict`` can be associated with all future instances
-of ``JSONEncodedDict`` in one step, using
-:meth:`~.Mutable.associate_with`.  This is similar to
-:meth:`~.Mutable.as_mutable` except it will intercept all occurrences
-of ``MutableDict`` in all mappings unconditionally, without
-the need to declare it individually::
-
-    MutableDict.associate_with(JSONEncodedDict)
-
-    class MyDataClass(Base):
-        __tablename__ = 'my_data'
-        id = Column(Integer, primary_key=True)
-        data = Column(JSONEncodedDict)
-
-
-Supporting Pickling
---------------------
-
-The key to the :mod:`sqlalchemy.ext.mutable` extension relies upon the
-placement of a ``weakref.WeakKeyDictionary`` upon the value object, which
-stores a mapping of parent mapped objects keyed to the attribute name under
-which they are associated with this value. ``WeakKeyDictionary`` objects are
-not picklable, due to the fact that they contain weakrefs and function
-callbacks. In our case, this is a good thing, since if this dictionary were
-picklable, it could lead to an excessively large pickle size for our value
-objects that are pickled by themselves outside of the context of the parent.
-The developer responsibility here is only to provide a ``__getstate__`` method
-that excludes the :meth:`~MutableBase._parents` collection from the pickle
-stream::
-
-    class MyMutableType(Mutable):
-        def __getstate__(self):
-            d = self.__dict__.copy()
-            d.pop('_parents', None)
-            return d
-
-With our dictionary example, we need to return the contents of the dict itself
-(and also restore them on __setstate__)::
-
-    class MutableDict(Mutable, dict):
-        # ....
-
-        def __getstate__(self):
-            return dict(self)
-
-        def __setstate__(self, state):
-            self.update(state)
-
-In the case that our mutable value object is pickled as it is attached to one
-or more parent objects that are also part of the pickle, the :class:`.Mutable`
-mixin will re-establish the :attr:`.Mutable._parents` collection on each value
-object as the owning parents themselves are unpickled.
-
-.. _mutable_composites:
-
-Establishing Mutability on Composites
-=====================================
-
-Composites are a special ORM feature which allow a single scalar attribute to
-be assigned an object value which represents information "composed" from one
-or more columns from the underlying mapped table. The usual example is that of
-a geometric "point", and is introduced in :ref:`mapper_composite`.
-
-.. versionchanged:: 0.7
-    The internals of :func:`.orm.composite` have been
-    greatly simplified and in-place mutation detection is no longer enabled by
-    default; instead, the user-defined value must detect changes on its own and
-    propagate them to all owning parents. The :mod:`sqlalchemy.ext.mutable`
-    extension provides the helper class :class:`.MutableComposite`, which is a
-    slight variant on the :class:`.Mutable` class.
-
-As is the case with :class:`.Mutable`, the user-defined composite class
-subclasses :class:`.MutableComposite` as a mixin, and detects and delivers
-change events to its parents via the :meth:`.MutableComposite.changed` method.
-In the case of a composite class, the detection is usually via the usage of
-Python descriptors (i.e. ``@property``), or alternatively via the special
-Python method ``__setattr__()``. Below we expand upon the ``Point`` class
-introduced in :ref:`mapper_composite` to subclass :class:`.MutableComposite`
-and to also route attribute set events via ``__setattr__`` to the
-:meth:`.MutableComposite.changed` method::
-
-    from sqlalchemy.ext.mutable import MutableComposite
-
-    class Point(MutableComposite):
-        def __init__(self, x, y):
-            self.x = x
-            self.y = y
-
-        def __setattr__(self, key, value):
-            "Intercept set events"
-
-            # set the attribute
-            object.__setattr__(self, key, value)
-
-            # alert all parents to the change
-            self.changed()
-
-        def __composite_values__(self):
-            return self.x, self.y
-
-        def __eq__(self, other):
-            return isinstance(other, Point) and \\
-                other.x == self.x and \\
-                other.y == self.y
-
-        def __ne__(self, other):
-            return not self.__eq__(other)
-
-The :class:`.MutableComposite` class uses a Python metaclass to automatically
-establish listeners for any usage of :func:`.orm.composite` that specifies our
-``Point`` type. Below, when ``Point`` is mapped to the ``Vertex`` class,
-listeners are established which will route change events from ``Point``
-objects to each of the ``Vertex.start`` and ``Vertex.end`` attributes::
-
-    from sqlalchemy.orm import composite, mapper
-    from sqlalchemy import Table, Column
-
-    vertices = Table('vertices', metadata,
-        Column('id', Integer, primary_key=True),
-        Column('x1', Integer),
-        Column('y1', Integer),
-        Column('x2', Integer),
-        Column('y2', Integer),
-        )
-
-    class Vertex(object):
-        pass
-
-    mapper(Vertex, vertices, properties={
-        'start': composite(Point, vertices.c.x1, vertices.c.y1),
-        'end': composite(Point, vertices.c.x2, vertices.c.y2)
-    })
-
-Any in-place changes to the ``Vertex.start`` or ``Vertex.end`` members
-will flag the attribute as "dirty" on the parent object::
-
-    >>> from sqlalchemy.orm import Session
-
-    >>> sess = Session()
-    >>> v1 = Vertex(start=Point(3, 4), end=Point(12, 15))
-    >>> sess.add(v1)
-    >>> sess.commit()
-
-    >>> v1.end.x = 8
-    >>> assert v1 in sess.dirty
-    True
-
-Coercing Mutable Composites
----------------------------
-
-The :meth:`.MutableBase.coerce` method is also supported on composite types.
-In the case of :class:`.MutableComposite`, the :meth:`.MutableBase.coerce`
-method is only called for attribute set operations, not load operations.
-Overriding the :meth:`.MutableBase.coerce` method is essentially equivalent
-to using a :func:`.validates` validation routine for all attributes which
-make use of the custom composite type::
-
-    class Point(MutableComposite):
-        # other Point methods
-        # ...
-
-        def coerce(cls, key, value):
-            if isinstance(value, tuple):
-                value = Point(*value)
-            elif not isinstance(value, Point):
-                raise ValueError("tuple or Point expected")
-            return value
-
-.. versionadded:: 0.7.10,0.8.0b2
-    Support for the :meth:`.MutableBase.coerce` method in conjunction with
-    objects of type :class:`.MutableComposite`.
-
-Supporting Pickling
---------------------
-
-As is the case with :class:`.Mutable`, the :class:`.MutableComposite` helper
-class uses a ``weakref.WeakKeyDictionary`` available via the
-:meth:`MutableBase._parents` attribute which isn't picklable. If we need to
-pickle instances of ``Point`` or its owning class ``Vertex``, we at least need
-to define a ``__getstate__`` that doesn't include the ``_parents`` dictionary.
-Below we define both a ``__getstate__`` and a ``__setstate__`` that package up
-the minimal form of our ``Point`` class::
-
-    class Point(MutableComposite):
-        # ...
-
-        def __getstate__(self):
-            return self.x, self.y
-
-        def __setstate__(self, state):
-            self.x, self.y = state
-
-As with :class:`.Mutable`, the :class:`.MutableComposite` augments the
-pickling process of the parent's object-relational state so that the
-:meth:`MutableBase._parents` collection is restored to all ``Point`` objects.

-"""A custom list that manages index/position information for contained
-elements.
-
-:author: Jason Kirtland
-
-``orderinglist`` is a helper for mutable ordered relationships.  It will
-intercept list operations performed on a :func:`.relationship`-managed
-collection and
-automatically synchronize changes in list position onto a target scalar
-attribute.
-
-Example: A ``slide`` table, where each row refers to zero or more entries
-in a related ``bullet`` table.   The bullets within a slide are
-displayed in order based on the value of the ``position`` column in the
-``bullet`` table.   As entries are reordered in memory, the value of the
-``position`` attribute should be updated to reflect the new sort order::
-
-
-    Base = declarative_base()
-
-    class Slide(Base):
-        __tablename__ = 'slide'
-
-        id = Column(Integer, primary_key=True)
-        name = Column(String)
-
-        bullets = relationship("Bullet", order_by="Bullet.position")
-
-    class Bullet(Base):
-        __tablename__ = 'bullet'
-        id = Column(Integer, primary_key=True)
-        slide_id = Column(Integer, ForeignKey('slide.id'))
-        position = Column(Integer)
-        text = Column(String)
-
-The standard relationship mapping will produce a list-like attribute on each
-``Slide`` containing all related ``Bullet`` objects,
-but coping with changes in ordering is not handled automatically.
-When appending a ``Bullet`` into ``Slide.bullets``, the ``Bullet.position``
-attribute will remain unset until manually assigned.   When the ``Bullet``
-is inserted into the middle of the list, the following ``Bullet`` objects
-will also need to be renumbered.
-
-The :class:`.OrderingList` object automates this task, managing the
-``position`` attribute on all ``Bullet`` objects in the collection.  It is
-constructed using the :func:`.ordering_list` factory::
-
-    from sqlalchemy.ext.orderinglist import ordering_list
-
-    Base = declarative_base()
-
-    class Slide(Base):
-        __tablename__ = 'slide'
-
-        id = Column(Integer, primary_key=True)
-        name = Column(String)
-
-        bullets = relationship("Bullet", order_by="Bullet.position",
-                                collection_class=ordering_list('position'))
-
-    class Bullet(Base):
-        __tablename__ = 'bullet'
-        id = Column(Integer, primary_key=True)
-        slide_id = Column(Integer, ForeignKey('slide.id'))
-        position = Column(Integer)
-        text = Column(String)
-
-With the above mapping the ``Bullet.position`` attribute is managed::
-
-    s = Slide()
-    s.bullets.append(Bullet())
-    s.bullets.append(Bullet())
-    s.bullets[1].position
-    >>> 1
-    s.bullets.insert(1, Bullet())
-    s.bullets[2].position
-    >>> 2
-
-The :class:`.OrderingList` construct only works with **changes** to a collection,
-and not the initial load from the database, and requires that the list be
-sorted when loaded.  Therefore, be sure to
-specify ``order_by`` on the :func:`.relationship` against the target ordering
-attribute, so that the ordering is correct when first loaded.
-
-.. warning::
-
-  :class:`.OrderingList` only provides limited functionality when a primary
-  key column or unique column is the target of the sort.  Operations
-  that are unsupported or are problematic include:
-
-    * two entries must trade values.  This is not supported directly in the
-      case of a primary key or unique constraint because it means at least
-      one row would need to be temporarily removed first, or changed to
-      a third, neutral value while the switch occurs.
-
-    * an entry must be deleted in order to make room for a new entry.
-      SQLAlchemy's unit of work performs all INSERTs before DELETEs within a
-      single flush.  In the case of a primary key, it will trade
-      an INSERT/DELETE of the same primary key for an UPDATE statement in order
-      to lessen the impact of this lmitation, however this does not take place
-      for a UNIQUE column.
-      A future feature will allow the "DELETE before INSERT" behavior to be
-      possible, allevating this limitation, though this feature will require
-      explicit configuration at the mapper level for sets of columns that
-      are to be handled in this way.
-
-:func:`.ordering_list` takes the name of the related object's ordering attribute as
-an argument.  By default, the zero-based integer index of the object's
-position in the :func:`.ordering_list` is synchronized with the ordering attribute:
-index 0 will get position 0, index 1 position 1, etc.  To start numbering at 1
-or some other integer, provide ``count_from=1``.

-
-          SQLAlchemy will add instances to the list via append() when your

-"""Serializer/Deserializer objects for usage with SQLAlchemy query structures,
-allowing "contextual" deserialization.
-
-Any SQLAlchemy query structure, either based on sqlalchemy.sql.*
-or sqlalchemy.orm.* can be used.  The mappers, Tables, Columns, Session
-etc. which are referenced by the structure are not persisted in serialized
-form, but are instead re-associated with the query structure
-when it is deserialized.
-
-Usage is nearly the same as that of the standard Python pickle module::
-
-    from sqlalchemy.ext.serializer import loads, dumps
-    metadata = MetaData(bind=some_engine)
-    Session = scoped_session(sessionmaker())
-
-    # ... define mappers
-
-    query = Session.query(MyClass).filter(MyClass.somedata=='foo').order_by(MyClass.sortkey)
-
-    # pickle the query
-    serialized = dumps(query)
-
-    # unpickle.  Pass in metadata + scoped_session
-    query2 = loads(serialized, metadata, Session)
-
-    print query2.all()
-
-Similar restrictions as when using raw pickle apply; mapped classes must be
-themselves be pickleable, meaning they are importable from a module-level
-namespace.
-
-The serializer module is only appropriate for query structures.  It is not
-needed for:
-
-* instances of user-defined classes.   These contain no references to engines,
-  sessions or expression constructs in the typical case and can be serialized
-  directly.
-
-* Table metadata that is to be loaded entirely from the serialized structure
-  (i.e. is not already declared in the application).   Regular
-  pickle.loads()/dumps() can be used to fully dump any ``MetaData`` object,
-  typically one which was reflected from an existing database at some previous
-  point in time.  The serializer module is specifically for the opposite case,
-  where the Table metadata is already present in memory.

-"""The inspection module provides the :func:`.inspect` function,
-which delivers runtime information about a wide variety
-of SQLAlchemy objects, both within the Core as well as the
-ORM.
-
-The :func:`.inspect` function is the entry point to SQLAlchemy's
-public API for viewing the configuration and construction
-of in-memory objects.   Depending on the type of object
-passed to :func:`.inspect`, the return value will either be
-a related object which provides a known interface, or in many
-cases it will return the object itself.
-
-The rationale for :func:`.inspect` is twofold.  One is that
-it replaces the need to be aware of a large variety of "information
-getting" functions in SQLAlchemy, such as :meth:`.Inspector.from_engine`,
-:func:`.orm.attributes.instance_state`, :func:`.orm.class_mapper`,
-and others.    The other is that the return value of :func:`.inspect`
-is guaranteed to obey a documented API, thus allowing third party
-tools which build on top of SQLAlchemy configurations to be constructed
-in a forwards-compatible way.

-    creation, pool check-out and check-in.  There are no events fired
-    when a connection closes.
-
-    For any given DB-API connection, there will be one ``connect``
-    event, `n` number of ``checkout`` events, and either `n` or `n - 1`
-    ``checkin`` events.  (If a ``Connection`` is detached from its
-    pool via the ``detach()`` method, it won't be checked back in.)
-
-    These are low-level events for low-level objects: raw Python

-    ``Connection`` wrapper, ``Dialect`` services or ``ClauseElement``

-    closing all cursors and other resources is recommended.
-
-    Events also receive a ``_ConnectionRecord``, a long-lived internal
-    ``Pool`` object that basically represents a "slot" in the

-    attribute of note: ``info``, a dictionary whose contents are
-    scoped to the lifetime of the DB-API connection managed by the
-    record.  You can use this shared storage area however you like.
-
-    There is no need to subclass ``PoolListener`` to handle events.
-    Any class that implements one or more of these methods can be used
-    as a pool listener.  The ``Pool`` will inspect the methods
-    provided by a listener object and add the listener to one or more
-    internal event queues based on its capabilities.  In terms of
-    efficiency and function call overhead, you're much better off only
-    providing implementations for the hooks you'll be using.

-"""Support for collections of mapped entities.
-
-The collections package supplies the machinery used to inform the ORM of
-collection membership changes.  An instrumentation via decoration approach is
-used, allowing arbitrary types (including built-ins) to be used as entity
-collections without requiring inheritance from a base class.
-
-Instrumentation decoration relays membership change events to the
-:class:`.CollectionAttributeImpl` that is currently managing the collection.
-The decorators observe function call arguments and return values, tracking
-entities entering or leaving the collection.  Two decorator approaches are
-provided.  One is a bundle of generic decorators that map function arguments
-and return values to events::
-
-  from sqlalchemy.orm.collections import collection
-  class MyClass(object):
-      # ...
-
-      @collection.adds(1)
-      def store(self, item):
-          self.data.append(item)
-
-      @collection.removes_return()
-      def pop(self):
-          return self.data.pop()
-
-
-The second approach is a bundle of targeted decorators that wrap appropriate
-append and remove notifiers around the mutation methods present in the
-standard Python ``list``, ``set`` and ``dict`` interfaces.  These could be
-specified in terms of generic decorator recipes, but are instead hand-tooled
-for increased efficiency.  The targeted decorators occasionally implement
-adapter-like behavior, such as mapping bulk-set methods (``extend``,
-``update``, ``__setslice__``, etc.) into the series of atomic mutation events
-that the ORM requires.
-
-The targeted decorators are used internally for automatic instrumentation of
-entity collection classes.  Every collection class goes through a
-transformation process roughly like so:
-
-1. If the class is a built-in, substitute a trivial sub-class
-2. Is this class already instrumented?
-3. Add in generic decorators
-4. Sniff out the collection interface through duck-typing
-5. Add targeted decoration to any undecorated interface method
-
-This process modifies the class at runtime, decorating methods and adding some
-bookkeeping properties.  This isn't possible (or desirable) for built-in
-classes like ``list``, so trivial sub-classes are substituted to hold
-decoration::
-
-  class InstrumentedList(list):
-      pass
-
-Collection classes can be specified in ``relationship(collection_class=)`` as
-types or a function that returns an instance.  Collection classes are
-inspected and instrumented during the mapper compilation phase.  The
-collection_class callable will be executed once to produce a specimen
-instance, and the type of that specimen will be instrumented.  Functions that
-return built-in types like ``lists`` will be adapted to produce instrumented
-instances.
-
-When extending a known type like ``list``, additional decorations are not
-generally not needed.  Odds are, the extension method will delegate to a
-method that's already instrumented.  For example::
-
-  class QueueIsh(list):
-     def push(self, item):
-         self.append(item)
-     def shift(self):
-         return self.pop(0)
-
-There's no need to decorate these methods.  ``append`` and ``pop`` are already
-instrumented as part of the ``list`` interface.  Decorating them would fire
-duplicate events, which should be avoided.
-
-The targeted decoration tries not to rely on other methods in the underlying
-collection class, but some are unavoidable.  Many depend on 'read' methods
-being present to properly instrument a 'write', for example, ``__setitem__``
-needs ``__getitem__``.  "Bulk" methods like ``update`` and ``extend`` may also
-reimplemented in terms of atomic appends and removes, so the ``extend``
-decoration will actually perform many ``append`` operations and not call the
-underlying method at all.
-
-Tight control over bulk operation and the firing of events is also possible by
-implementing the instrumentation internally in your methods.  The basic
-instrumentation package works under the general assumption that collection
-mutation will not raise unusual exceptions.  If you want to closely
-orchestrate append and remove events with exception management, internal
-instrumentation may be the answer.  Within your method,
-``collection_adapter(self)`` will retrieve an object that you can use for
-explicit control over triggering append and remove events.
-
-The owning object and :class:`.CollectionAttributeImpl` are also reachable
-through the adapter, allowing for some very sophisticated behavior.

-
-    A single mapper can maintain a chain of ``MapperExtension``
-    objects. When a particular mapping event occurs, the
-    corresponding method on each ``MapperExtension`` is invoked
-    serially, and each method has the ability to halt the chain
-    from proceeding further::
-
-        m = mapper(User, users_table, extension=[ext1, ext2, ext3])
-
-    Each ``MapperExtension`` method returns the symbol
-    EXT_CONTINUE by default.   This symbol generally means "move
-    to the next ``MapperExtension`` for processing".  For methods
-    that return objects like translated rows or new object
-    instances, EXT_CONTINUE means the result of the method
-    should be ignored.   In some cases it's required for a
-    default mapper activity to be performed, such as adding a
-    new instance to a result list.
-
-    The symbol EXT_STOP has significance within a chain
-    of ``MapperExtension`` objects that the chain will be stopped
-    when this symbol is returned.  Like EXT_CONTINUE, it also
-    has additional significance in some cases that a default
-    mapper activity will not be performed.

-    These are typically defined on the class-bound descriptor for the
-    target class.
-
-    e.g.::
-
-        from sqlalchemy import event
-
-        def my_append_listener(target, value, initiator):
-            print "received append event for target: %s" % target
-
-        event.listen(MyClass.collection, 'append', my_append_listener)
-
-    Listeners have the option to return a possibly modified version
-    of the value, when the ``retval=True`` flag is passed
-    to :func:`~.event.listen`::
-
-        def validate_phone(target, value, oldvalue, initiator):
-            "Strip non-numeric characters from a phone number"
-
-            return re.sub(r'(?![0-9])', '', value)
-
-        # setup listener on UserContact.phone attribute, instructing
-        # it to use the return value
-        listen(UserContact.phone, 'set', validate_phone, retval=True)
-
-    A validation function like the above can also raise an exception
-    such as :exc:`ValueError` to halt the operation.
-
-    Several modifiers are available to the :func:`~.event.listen` function.
-
-    :param active_history=False: When True, indicates that the
-      "set" event would like to receive the "old" value being
-      replaced unconditionally, even if this requires firing off
-      database loads. Note that ``active_history`` can also be
-      set directly via :func:`.column_property` and
-      :func:`.relationship`.
-
-    :param propagate=False: When True, the listener function will
-      be established not just for the class attribute given, but
-      for attributes of the same name on all current subclasses
-      of that class, as well as all future subclasses of that
-      class, using an additional listener that listens for
-      instrumentation events.
-    :param raw=False: When True, the "target" argument to the
-      event will be the :class:`.InstanceState` management
-      object, rather than the mapped instance itself.
-    :param retval=False: when True, the user-defined event
-      listening must return the "value" argument from the
-      function.  This gives the listening function the opportunity
-      to change the value that is ultimately used for a "set"
-      or "append" event.

-"""Defines SQLAlchemy's system of class instrumentation.
-
-This module is usually not directly visible to user applications, but
-defines a large part of the ORM's interactivity.
-
-instrumentation.py deals with registration of end-user classes
-for state tracking.   It interacts closely with state.py
-and attributes.py which establish per-instance and per-class-attribute
-instrumentation, respectively.
-
-The class instrumentation system can be customized on a per-class
-or global basis using the :mod:`sqlalchemy.ext.instrumentation`
-module, which provides the means to build and specify
-alternate instrumentation forms.
-
-.. versionchanged: 0.8
-   The instrumentation extension system was moved out of the
-   ORM and into the external :mod:`sqlalchemy.ext.instrumentation`
-   package.  When that package is imported, it installs
-   itself within sqlalchemy.orm so that its more comprehensive
-   resolution mechanics take effect.

-        This function is typically used behind the scenes

-        by the Declarative extension itself, including ``class_``,
-        ``local_table``, ``properties``, and  ``inherits``.
-        Other options are passed to :func:`.mapper` using
-        the ``__mapper_args__`` class variable::
-
-           class MyClass(Base):

-               id = Column(Integer, primary_key=True)

-        Explicit use of :func:`.mapper`
-        is often referred to as *classical mapping*.  The above

-           inheritance.   When using Declarative, this argument is

-           is configured via the ``__table__`` argument or via the
-           :class:`.Table` produced as a result of the ``__tablename__``

-           class will overwrite all data within object instances that already

-           possibly existing within the database. This affects whether a
-           mapper will assign an incoming row to an existing identity, as well
-           as if :meth:`.Session.merge` will check the database first for a
-           particular primary key value. A "partial primary key" can occur if
-           one has mapped to an OUTER JOIN, for example.
-
-        :param batch: Defaults to ``True``, indicating that save operations
-           of multiple entities can be batched together for efficiency.
-           Setting to False indicates
-           that an instance will be fully saved before saving the next
-           instance.  This is used in the extremely rare case that a
-           :class:`.MapperEvents` listener requires being called
-           in between individual row persistence operations.
-
-        :param column_prefix: A string which will be prepended
-           to the mapped attribute name when :class:`.Column`
-           objects are automatically assigned as attributes to the
-           mapped class.  Does not affect explicitly specified
-           column-based properties.
-
-           See the section :ref:`column_prefix` for an example.
-
-        :param concrete: If True, indicates this mapper should use concrete
-           table inheritance with its parent mapper.
-
-           See the section :ref:`concrete_inheritance` for an example.
-
-        :param confirm_deleted_rows: defaults to True; when a DELETE occurs
-          of one more more rows based on specific primary keys, a warning is
-          emitted when the number of rows matched does not equal the number
-          of rows expected.  This parameter may be set to False to handle the case
-          where database ON DELETE CASCADE rules may be deleting some of those
-          rows automatically.  The warning may be changed to an exception
-          in a future release.
-
-          .. versionadded:: 0.9.4 - added :paramref:`.mapper.confirm_deleted_rows`
-             as well as conditional matched row checking on delete.
-
-        :param eager_defaults: if True, the ORM will immediately fetch the
-          value of server-generated default values after an INSERT or UPDATE,
-          rather than leaving them as expired to be fetched on next access.
-          This can be used for event schemes where the server-generated values
-          are needed immediately before the flush completes.   By default,
-          this scheme will emit an individual ``SELECT`` statement per row
-          inserted or updated, which note can add significant performance
-          overhead.  However, if the
-          target database supports :term:`RETURNING`, the default values will be
-          returned inline with the INSERT or UPDATE statement, which can
-          greatly enhance performance for an application that needs frequent
-          access to just-generated server defaults.
-
-          .. versionchanged:: 0.9.0 The ``eager_defaults`` option can now
-             make use of :term:`RETURNING` for backends which support it.
-
-        :param exclude_properties: A list or set of string column names to
-          be excluded from mapping.
-
-          See :ref:`include_exclude_cols` for an example.
-
-        :param extension: A :class:`.MapperExtension` instance or
-           list of :class:`.MapperExtension` instances which will be applied
-           to all operations by this :class:`.Mapper`.  **Deprecated.**
-           Please see :class:`.MapperEvents`.
-
-        :param include_properties: An inclusive list or set of string column
-          names to map.
-
-          See :ref:`include_exclude_cols` for an example.
-
-        :param inherits: A mapped class or the corresponding :class:`.Mapper`
-          of one indicating a superclass to which this :class:`.Mapper`
-          should *inherit* from.   The mapped class here must be a subclass
-          of the other mapper's class.   When using Declarative, this argument
-          is passed automatically as a result of the natural class
-          hierarchy of the declared classes.
-
-          .. seealso::
-
-            :ref:`inheritance_toplevel`
-
-        :param inherit_condition: For joined table inheritance, a SQL
-           expression which will
-           define how the two tables are joined; defaults to a natural join
-           between the two tables.
-
-        :param inherit_foreign_keys: When ``inherit_condition`` is used and the
-           columns present are missing a :class:`.ForeignKey` configuration,
-           this parameter can be used to specify which columns are "foreign".
-           In most cases can be left as ``None``.
-
-        :param legacy_is_orphan: Boolean, defaults to ``False``.
-          When ``True``, specifies that "legacy" orphan consideration
-          is to be applied to objects mapped by this mapper, which means
-          that a pending (that is, not persistent) object is auto-expunged
-          from an owning :class:`.Session` only when it is de-associated
-          from *all* parents that specify a ``delete-orphan`` cascade towards
-          this mapper.  The new default behavior is that the object is auto-expunged
-          when it is de-associated with *any* of its parents that specify
-          ``delete-orphan`` cascade.  This behavior is more consistent with
-          that of a persistent object, and allows behavior to be consistent
-          in more scenarios independently of whether or not an orphanable
-          object has been flushed yet or not.
-
-          See the change note and example at :ref:`legacy_is_orphan_addition`
-          for more detail on this change.
-
-          .. versionadded:: 0.8 - the consideration of a pending object as
-            an "orphan" has been modified to more closely match the
-            behavior as that of persistent objects, which is that the object
-            is expunged from the :class:`.Session` as soon as it is
-            de-associated from any of its orphan-enabled parents.  Previously,
-            the pending object would be expunged only if de-associated
-            from all of its orphan-enabled parents. The new flag ``legacy_is_orphan``
-            is added to :func:`.orm.mapper` which re-establishes the
-            legacy behavior.
-
-        :param non_primary: Specify that this :class:`.Mapper` is in addition
-          to the "primary" mapper, that is, the one used for persistence.
-          The :class:`.Mapper` created here may be used for ad-hoc
-          mapping of the class to an alternate selectable, for loading
-          only.
-
-          :paramref:`.Mapper.non_primary` is not an often used option, but
-          is useful in some specific :func:`.relationship` cases.
-
-          .. seealso::
-
-              :ref:`relationship_non_primary_mapper`
-
-        :param order_by: A single :class:`.Column` or list of :class:`.Column`
-           objects for which selection operations should use as the default
-           ordering for entities.  By default mappers have no pre-defined
-           ordering.
-
-        :param passive_updates: Indicates UPDATE behavior of foreign key
-           columns when a primary key column changes on a joined-table
-           inheritance mapping.   Defaults to ``True``.
-
-           When True, it is assumed that ON UPDATE CASCADE is configured on
-           the foreign key in the database, and that the database will handle
-           propagation of an UPDATE from a source column to dependent columns
-           on joined-table rows.
-
-           When False, it is assumed that the database does not enforce
-           referential integrity and will not be issuing its own CASCADE
-           operation for an update.  The unit of work process will
-           emit an UPDATE statement for the dependent columns during a
-           primary key change.

-
-        :param polymorphic_on: Specifies the column, attribute, or
-          SQL expression used to determine the target class for an
-          incoming row, when inheriting classes are present.
-
-          This value is commonly a :class:`.Column` object that's
-          present in the mapped :class:`.Table`::
-
-            class Employee(Base):
-                __tablename__ = 'employee'
-
-                id = Column(Integer, primary_key=True)
-                discriminator = Column(String(50))
-
-                __mapper_args__ = {
-                    "polymorphic_on":discriminator,
-                    "polymorphic_identity":"employee"
-                }
-
-          It may also be specified
-          as a SQL expression, as in this example where we
-          use the :func:`.case` construct to provide a conditional
-          approach::
-
-            class Employee(Base):
-                __tablename__ = 'employee'
-
-                id = Column(Integer, primary_key=True)
-                discriminator = Column(String(50))
-
-                __mapper_args__ = {
-                    "polymorphic_on":case([
-                        (discriminator == "EN", "engineer"),
-                        (discriminator == "MA", "manager"),
-                    ], else_="employee"),
-                    "polymorphic_identity":"employee"
-                }
-
-          It may also refer to any attribute
-          configured with :func:`.column_property`, or to the
-          string name of one::
-
-                class Employee(Base):
-                    __tablename__ = 'employee'
-
-                    id = Column(Integer, primary_key=True)
-                    discriminator = Column(String(50))
-                    employee_type = column_property(
-                        case([
-                            (discriminator == "EN", "engineer"),
-                            (discriminator == "MA", "manager"),
-                        ], else_="employee")
-                    )
-
-                    __mapper_args__ = {
-                        "polymorphic_on":employee_type,
-                        "polymorphic_identity":"employee"
-                    }
-
-          .. versionchanged:: 0.7.4
-              ``polymorphic_on`` may be specified as a SQL expression,
-              or refer to any attribute configured with
-              :func:`.column_property`, or to the string name of one.
-
-          When setting ``polymorphic_on`` to reference an
-          attribute or expression that's not present in the
-          locally mapped :class:`.Table`, yet the value
-          of the discriminator should be persisted to the database,
-          the value of the
-          discriminator is not automatically set on new
-          instances; this must be handled by the user,
-          either through manual means or via event listeners.
-          A typical approach to establishing such a listener
-          looks like::
-
-                from sqlalchemy import event
-                from sqlalchemy.orm import object_mapper
-
-                @event.listens_for(Employee, "init", propagate=True)
-                def set_identity(instance, *arg, **kw):
-                    mapper = object_mapper(instance)
-                    instance.discriminator = mapper.polymorphic_identity
-
-          Where above, we assign the value of ``polymorphic_identity``
-          for the mapped class to the ``discriminator`` attribute,
-          thus persisting the value to the ``discriminator`` column
-          in the database.
-
-          .. seealso::
-
-            :ref:`inheritance_toplevel`
-
-        :param polymorphic_identity: Specifies the value which
-          identifies this particular class as returned by the
-          column expression referred to by the ``polymorphic_on``
-          setting.  As rows are received, the value corresponding
-          to the ``polymorphic_on`` column expression is compared
-          to this value, indicating which subclass should
-          be used for the newly reconstructed object.
-
-        :param properties: A dictionary mapping the string names of object
-           attributes to :class:`.MapperProperty` instances, which define the
-           persistence behavior of that attribute.  Note that :class:`.Column`
-           objects present in
-           the mapped :class:`.Table` are automatically placed into
-           ``ColumnProperty`` instances upon mapping, unless overridden.
-           When using Declarative, this argument is passed automatically,
-           based on all those :class:`.MapperProperty` instances declared
-           in the declared class body.
-
-        :param primary_key: A list of :class:`.Column` objects which define the
-           primary key to be used against this mapper's selectable unit.
-           This is normally simply the primary key of the ``local_table``, but
-           can be overridden here.
-
-        :param version_id_col: A :class:`.Column`
-           that will be used to keep a running version id of rows
-           in the table.  This is used to detect concurrent updates or
-           the presence of stale data in a flush.  The methodology is to
-           detect if an UPDATE statement does not match the last known
-           version id, a
-           :class:`~sqlalchemy.orm.exc.StaleDataError` exception is
-           thrown.
-           By default, the column must be of :class:`.Integer` type,
-           unless ``version_id_generator`` specifies an alternative version
-           generator.

-              and rationale.
-
-        :param version_id_generator: Define how new version ids should
-          be generated.  Defaults to ``None``, which indicates that
-          a simple integer counting scheme be employed.  To provide a custom
-          versioning scheme, provide a callable function of the form::
-
-              def generate_version(version):
-                  return next_version
-
-          Alternatively, server-side versioning functions such as triggers,
-          or programmatic versioning schemes outside of the version id generator
-          may be used, by specifying the value ``False``.
-          Please see :ref:`server_side_version_counter` for a discussion
-          of important points when using this option.

-            loading, that is, which tables are queried at once. <classes> is

-        Use this function when the given column is not directly present within the

-        scalar SELECT queries.
-

-        :param deferred:

-              it does not load immediately, and is instead loaded when the
-              attribute is first accessed on an instance.  See also

-            Disable expiry on flush.   A column_property() which refers
-            to a SQL expression (and not a single table-bound column)
-            is considered to be a "read only" property; populating it
-            has no effect on the state of data, and it can only return
-            database state.   For this reason a column_property()'s value
-            is expired whenever the parent object is involved in a
-            flush, that is, has any kind of "dirty" state within a flush.
-            Setting this parameter to ``False`` will have the effect of
-            leaving any existing value present after the flush proceeds.
-            Note however that the :class:`.Session` with default expiration
-            settings still expires
-            all attributes after a :meth:`.Session.commit` call, however.

-"""The Query class and support.
-
-Defines the :class:`.Query` class, the central
-construct used by the ORM to construct database queries.
-
-The :class:`.Query` class should not be confused with the
-:class:`.Select` class, which defines database
-SELECT operations at the SQL (non-ORM) level.  ``Query`` differs from
-``Select`` in that it returns ORM-mapped objects and interacts with an
-ORM session, whereas the ``Select`` construct interacts directly with the
-database to return iterable result sets.

-        The method accepts multiple Query objects so as to control
-        the level of nesting.  A series of ``union()`` calls such as::
-
-            x.union(y).union(z).all()
-
-        will nest on each ``union()``, and produces::
-
-            SELECT * FROM (SELECT * FROM (SELECT * FROM X UNION
-                            SELECT * FROM y) UNION SELECT * FROM Z)
-
-        Whereas::
-
-            x.union(y, z).all()
-
-        produces::
-
-            SELECT * FROM (SELECT * FROM X UNION SELECT * FROM y UNION
-                            SELECT * FROM Z)
-
-        Note that many database backends do not allow ORDER BY to
-        be rendered on a query called within UNION, EXCEPT, etc.
-        To disable all ORDER BY clauses including those configured
-        on mappers, issue ``query.order_by(None)`` - the resulting
-        :class:`.Query` object will not render ORDER BY within
-        its SELECT statement.

-        and apply generatively, returning the newly resulting :class:`.Query`.
-
-        **Simple Relationship Joins**
-
-        Consider a mapping between two classes ``User`` and ``Address``,
-        with a relationship ``User.addresses`` representing a collection
-        of ``Address`` objects associated with each ``User``.   The most common
-        usage of :meth:`~.Query.join` is to create a JOIN along this
-        relationship, using the ``User.addresses`` attribute as an indicator
-        for how this should occur::
-
-            q = session.query(User).join(User.addresses)
-
-        Where above, the call to :meth:`~.Query.join` along ``User.addresses``
-        will result in SQL equivalent to::
-
-            SELECT user.* FROM user JOIN address ON user.id = address.user_id
-
-        In the above example we refer to ``User.addresses`` as passed to
-        :meth:`~.Query.join` as the *on clause*, that is, it indicates
-        how the "ON" portion of the JOIN should be constructed.  For a
-        single-entity query such as the one above (i.e. we start by selecting
-        only from ``User`` and nothing else), the relationship can also be
-        specified by its string name::
-
-            q = session.query(User).join("addresses")
-
-        :meth:`~.Query.join` can also accommodate multiple
-        "on clause" arguments to produce a chain of joins, such as below
-        where a join across four related entities is constructed::
-
-            q = session.query(User).join("orders", "items", "keywords")
-
-        The above would be shorthand for three separate calls to
-        :meth:`~.Query.join`, each using an explicit attribute to indicate
-        the source entity::
-
-            q = session.query(User).\\
-                    join(User.orders).\\
-                    join(Order.items).\\
-                    join(Item.keywords)
-
-        **Joins to a Target Entity or Selectable**
-
-        A second form of :meth:`~.Query.join` allows any mapped entity
-        or core selectable construct as a target.   In this usage,
-        :meth:`~.Query.join` will attempt
-        to create a JOIN along the natural foreign key relationship between
-        two entities::
-
-            q = session.query(User).join(Address)
-
-        The above calling form of :meth:`~.Query.join` will raise an error if
-        either there are no foreign keys between the two entities, or if
-        there are multiple foreign key linkages between them.   In the
-        above calling form, :meth:`~.Query.join` is called upon to
-        create the "on clause" automatically for us.  The target can
-        be any mapped entity or selectable, such as a :class:`.Table`::
-
-            q = session.query(User).join(addresses_table)
-
-        **Joins to a Target with an ON Clause**
-
-        The third calling form allows both the target entity as well
-        as the ON clause to be passed explicitly.   Suppose for
-        example we wanted to join to ``Address`` twice, using
-        an alias the second time.  We use :func:`~sqlalchemy.orm.aliased`
-        to create a distinct alias of ``Address``, and join
-        to it using the ``target, onclause`` form, so that the
-        alias can be specified explicitly as the target along with
-        the relationship to instruct how the ON clause should proceed::
-
-            a_alias = aliased(Address)
-
-            q = session.query(User).\\
-                    join(User.addresses).\\
-                    join(a_alias, User.addresses).\\
-                    filter(Address.email_address=='ed@foo.com').\\
-                    filter(a_alias.email_address=='ed@bar.com')
-
-        Where above, the generated SQL would be similar to::
-
-            SELECT user.* FROM user
-                JOIN address ON user.id = address.user_id
-                JOIN address AS address_1 ON user.id=address_1.user_id
-                WHERE address.email_address = :email_address_1
-                AND address_1.email_address = :email_address_2
-
-        The two-argument calling form of :meth:`~.Query.join`
-        also allows us to construct arbitrary joins with SQL-oriented
-        "on clause" expressions, not relying upon configured relationships
-        at all.  Any SQL expression can be passed as the ON clause
-        when using the two-argument form, which should refer to the target
-        entity in some way as well as an applicable source entity::
-
-            q = session.query(User).join(Address, User.id==Address.user_id)
-
-        .. versionchanged:: 0.7
-            In SQLAlchemy 0.6 and earlier, the two argument form of
-            :meth:`~.Query.join` requires the usage of a tuple:
-            ``query(User).join((Address, User.id==Address.user_id))``\ .
-            This calling form is accepted in 0.7 and further, though
-            is not necessary unless multiple join conditions are passed to
-            a single :meth:`~.Query.join` call, which itself is also not
-            generally necessary as it is now equivalent to multiple
-            calls (this wasn't always the case).
-
-        **Advanced Join Targeting and Adaption**
-
-        There is a lot of flexibility in what the "target" can be when using
-        :meth:`~.Query.join`.   As noted previously, it also accepts
-        :class:`.Table` constructs and other selectables such as
-        :func:`.alias` and :func:`.select` constructs, with either the one
-        or two-argument forms::
-
-            addresses_q = select([Address.user_id]).\\
-                        where(Address.email_address.endswith("@bar.com")).\\
-                        alias()
-
-            q = session.query(User).\\
-                        join(addresses_q, addresses_q.c.user_id==User.id)
-
-        :meth:`~.Query.join` also features the ability to *adapt* a
-        :meth:`~sqlalchemy.orm.relationship` -driven ON clause to the target
-        selectable. Below we construct a JOIN from ``User`` to a subquery
-        against ``Address``, allowing the relationship denoted by
-        ``User.addresses`` to *adapt* itself to the altered target::
-
-            address_subq = session.query(Address).\\
-                            filter(Address.email_address == 'ed@foo.com').\\
-                            subquery()
-
-            q = session.query(User).join(address_subq, User.addresses)
-
-        Producing SQL similar to::
-
-            SELECT user.* FROM user
-                JOIN (
-                    SELECT address.id AS id,
-                            address.user_id AS user_id,
-                            address.email_address AS email_address
-                    FROM address
-                    WHERE address.email_address = :email_address_1
-                ) AS anon_1 ON user.id = anon_1.user_id
-
-        The above form allows one to fall back onto an explicit ON
-        clause at any time::
-
-            q = session.query(User).\\
-                    join(address_subq, User.id==address_subq.c.user_id)
-
-        **Controlling what to Join From**
-
-        While :meth:`~.Query.join` exclusively deals with the "right"
-        side of the JOIN, we can also control the "left" side, in those
-        cases where it's needed, using :meth:`~.Query.select_from`.
-        Below we construct a query against ``Address`` but can still
-        make usage of ``User.addresses`` as our ON clause by instructing
-        the :class:`.Query` to select first from the ``User``
-        entity::
-
-            q = session.query(Address).select_from(User).\\
-                            join(User.addresses).\\
-                            filter(User.name == 'ed')
-
-        Which will produce SQL similar to::
-
-            SELECT address.* FROM user
-                JOIN address ON user.id=address.user_id
-                WHERE user.name = :name_1
-
-        **Constructing Aliases Anonymously**
-
-        :meth:`~.Query.join` can construct anonymous aliases
-        using the ``aliased=True`` flag.  This feature is useful
-        when a query is being joined algorithmically, such as
-        when querying self-referentially to an arbitrary depth::
-
-            q = session.query(Node).\\
-                    join("children", "children", aliased=True)
-
-        When ``aliased=True`` is used, the actual "alias" construct
-        is not explicitly available.  To work with it, methods such as
-        :meth:`.Query.filter` will adapt the incoming entity to
-        the last join point::
-
-            q = session.query(Node).\\
-                    join("children", "children", aliased=True).\\
-                    filter(Node.name == 'grandchild 1')
-
-        When using automatic aliasing, the ``from_joinpoint=True``
-        argument can allow a multi-node join to be broken into
-        multiple calls to :meth:`~.Query.join`, so that
-        each path along the way can be further filtered::
-
-            q = session.query(Node).\\
-                    join("children", aliased=True).\\
-                    filter(Node.name='child 1').\\
-                    join("children", aliased=True, from_joinpoint=True).\\
-                    filter(Node.name == 'grandchild 1')
-
-        The filtering aliases above can then be reset back to the
-        original ``Node`` entity using :meth:`~.Query.reset_joinpoint`::
-
-            q = session.query(Node).\\
-                    join("children", "children", aliased=True).\\
-                    filter(Node.name == 'grandchild 1').\\
-                    reset_joinpoint().\\
-                    filter(Node.name == 'parent 1)
-
-        For an example of ``aliased=True``, see the distribution
-        example :ref:`examples_xmlpersistence` which illustrates
-        an XPath-like query system using algorithmic joins.
-
-        :param \*props: A collection of one or more join conditions,
-         each consisting of a relationship-bound attribute or string
-         relationship name representing an "on clause", or a single
-         target entity, or a tuple in the form of ``(target, onclause)``.
-         A special two-argument calling form of the form ``target, onclause``
-         is also accepted.
-        :param aliased=False: If True, indicate that the JOIN target should be
-         anonymously aliased.  Subsequent calls to :meth:`~.Query.filter`
-         and similar will adapt the incoming criterion to the target
-         alias, until :meth:`~.Query.reset_joinpoint` is called.
-        :param from_joinpoint=False: When using ``aliased=True``, a setting
-         of True here will cause the join to be from the most recent
-         joined target, rather than starting back from the original
-         FROM clauses of the query.

-
-        This method is similar to the :meth:`.Query.select_from`
-        method, in that it sets the FROM clause of the query.  However,

-        to replace the FROM which the selected entities would normally
-        select from.
-
-        The given ``from_obj`` must be an instance of a :class:`.FromClause`,
-        e.g. a :func:`.select` or :class:`.Alias` construct.
-
-        An example would be a :class:`.Query` that selects ``User`` entities,
-        but uses :meth:`.Query.select_entity_from` to have the entities
-        selected from a :func:`.select` construct instead of the
-        base ``user`` table::
-
-            select_stmt = select([User]).where(User.id == 7)
-
-            q = session.query(User).\\
-                    select_entity_from(select_stmt).\\
-                    filter(User.name == 'ed')
-
-        The query generated will select ``User`` entities directly
-        from the given :func:`.select` construct, and will be::
-
-            SELECT anon_1.id AS anon_1_id, anon_1.name AS anon_1_name
-            FROM (SELECT "user".id AS id, "user".name AS name
-            FROM "user"
-            WHERE "user".id = :id_1) AS anon_1
-            WHERE anon_1.name = :name_1
-
-        Notice above that even the WHERE criterion was "adapted" such that
-        the ``anon_1`` subquery effectively replaces all references to the

-        Compare this to :meth:`.Query.select_from`, which as of
-        version 0.9, does not affect existing entities.  The
-        statement below::
-
-            q = session.query(User).\\
-                    select_from(select_stmt).\\
-                    filter(User.name == 'ed')
-
-        Produces SQL where both the ``user`` table as well as the
-        ``select_stmt`` construct are present as separate elements
-        in the FROM clause.  No "adaptation" of the ``user`` table
-        is applied::
-
-            SELECT "user".id AS user_id, "user".name AS user_name
-            FROM "user", (SELECT "user".id AS id, "user".name AS name
-            FROM "user"
-            WHERE "user".id = :id_1) AS anon_1
-            WHERE "user".name = :name_1
-
-        :meth:`.Query.select_entity_from` maintains an older
-        behavior of :meth:`.Query.select_from`.  In modern usage,
-        similar results can also be achieved using :func:`.aliased`::
-
-            select_stmt = select([User]).where(User.id == 7)
-            user_from_select = aliased(User, select_stmt.alias())

-

-            :meth:`.Query.select_entity_from` was added to specify
-            the specific behavior of entity replacement, however
-            the :meth:`.Query.select_from` maintains this behavior
-            as well until 0.9.

-
-        This corresponds to a parent-child or associative table relationship.  The
-        constructed class is an instance of :class:`.RelationshipProperty`.
-
-        A typical :func:`.relationship`, used in a classical mapping::
-
-           mapper(Parent, properties={
-             'children': relationship(Child)
-           })
-
-        Some arguments accepted by :func:`.relationship` optionally accept a
-        callable function, which when called produces the desired value.
-        The callable is invoked by the parent :class:`.Mapper` at "mapper
-        initialization" time, which happens only when mappers are first used, and
-        is assumed to be after all mappings have been constructed.  This can be
-        used to resolve order-of-declaration and other dependency issues, such as
-        if ``Child`` is declared below ``Parent`` in the same file::
-
-            mapper(Parent, properties={
-                "children":relationship(lambda: Child,
-                                    order_by=lambda: Child.id)
-            })
-
-        When using the :ref:`declarative_toplevel` extension, the Declarative
-        initializer allows string arguments to be passed to :func:`.relationship`.
-        These string arguments are converted into callables that evaluate
-        the string as Python code, using the Declarative
-        class-registry as a namespace.  This allows the lookup of related
-        classes to be automatic via their string name, and removes the need to
-        import related classes at all into the local module space::
-
-            from sqlalchemy.ext.declarative import declarative_base
-
-            Base = declarative_base()
-
-            class Parent(Base):

-
-        :param argument:
-          a mapped class, or actual :class:`.Mapper` instance, representing the
-          target of the relationship.
-
-          :paramref:`~.relationship.argument` may also be passed as a callable function
-          which is evaluated at mapper initialization time, and may be passed as a
-          Python-evaluable string when using Declarative.

-
-        :param secondary:
-          for a many-to-many relationship, specifies the intermediary
-          table, and is typically an instance of :class:`.Table`.
-          In less common circumstances, the argument may also be specified
-          as an :class:`.Alias` construct, or even a :class:`.Join` construct.
-
-          :paramref:`~.relationship.secondary` may
-          also be passed as a callable function which is evaluated at
-          mapper initialization time.  When using Declarative, it may also
-          be a string argument noting the name of a :class:`.Table` that is
-          present in the :class:`.MetaData` collection associated with the
-          parent-mapped :class:`.Table`.
-
-          The :paramref:`~.relationship.secondary` keyword argument is typically
-          applied in the case where the intermediary :class:`.Table` is not
-          otherwise exprssed in any direct class mapping. If the "secondary" table
-          is also explicitly mapped elsewhere
-          (e.g. as in :ref:`association_pattern`), one should consider applying
-          the :paramref:`~.relationship.viewonly` flag so that this :func:`.relationship`
-          is not used for persistence operations which may conflict with those
-          of the association object pattern.

-
-              :ref:`composite_secondary_join` - a lesser-used pattern which in some
-              cases can enable complex :func:`.relationship` SQL conditions

-
-          .. versionadded:: 0.9.2 :paramref:`~.relationship.secondary` works
-             more effectively when referring to a :class:`.Join` instance.
-
-        :param active_history=False:
-          When ``True``, indicates that the "previous" value for a
-          many-to-one reference should be loaded when replaced, if
-          not already loaded. Normally, history tracking logic for
-          simple many-to-ones only needs to be aware of the "new"
-          value in order to perform a flush. This flag is available
-          for applications that make use of
-          :func:`.attributes.get_history` which also need to know
-          the "previous" value of the attribute.
-
-        :param backref:
-          indicates the string name of a property to be placed on the related

-          direction. The other property will be created automatically
-          when the mappers are configured.  Can also be passed as a
-          :func:`.backref` object to control the configuration of the
-          new relationship.

-          except the complementing property is **not** created automatically,
-          and instead must be configured explicitly on the other mapper.  The
-          complementing property should also indicate :paramref:`~.relationship.back_populates`
-          to this relationship to ensure proper functioning.

-
-        :param cascade:
-          a comma-separated list of cascade rules which determines how
-          Session operations should be "cascaded" from parent to child.
-          This defaults to ``False``, which means the default cascade
-          should be used - this default cascade is ``"save-update, merge"``.
-
-          The available cascades are ``save-update``, ``merge``,
-          ``expunge``, ``delete``, ``delete-orphan``, and ``refresh-expire``.
-          An additional option, ``all`` indicates shorthand for
-          ``"save-update, merge, refresh-expire,
-          expunge, delete"``, and is often used as in ``"all, delete-orphan"``
-          to indicate that related objects should follow along with the
-          parent object in all cases, and be deleted when de-associated.

-            a delete cascade.
-
-        :param cascade_backrefs=True:
-          a boolean value indicating if the ``save-update`` cascade should
-          operate along an assignment event intercepted by a backref.
-          When set to ``False``, the attribute managed by this relationship
-          will not cascade an incoming transient object into the session of a
-          persistent parent, if the event is received via backref.

-        :param collection_class:
-          a class or callable that returns a new list-holding object. will
-          be used in place of a plain list for storing elements.

-
-
-        :param distinct_target_key=None:
-          Indicate if a "subquery" eager load should apply the DISTINCT
-          keyword to the innermost SELECT statement.  When left as ``None``,
-          the DISTINCT keyword will be applied in those cases when the target
-          columns do not comprise the full primary key of the target table.
-          When set to ``True``, the DISTINCT keyword is applied to the innermost
-          SELECT unconditionally.
-
-          It may be desirable to set this flag to False when the DISTINCT is
-          reducing performance of the innermost subquery beyond that of what
-          duplicate innermost rows may be causing.
-
-          .. versionadded:: 0.8.3 - :paramref:`~.relationship.distinct_target_key`
-             allows the
-             subquery eager loader to apply a DISTINCT modifier to the
-             innermost SELECT.
-
-          .. versionchanged:: 0.9.0 - :paramref:`~.relationship.distinct_target_key`
-             now defaults to ``None``, so that the feature enables itself automatically for
-             those cases where the innermost query targets a non-unique
-             key.

-          the resulting descriptor placed on the class.
-
-          .. deprecated:: 0.7 Please see :class:`.AttributeEvents`.
-
-        :param foreign_keys:
-
-          a list of columns which are to be used as "foreign key"
-          columns, or columns which refer to the value in a remote
-          column, within the context of this :func:`.relationship`
-          object's :paramref:`~.relationship.primaryjoin` condition.
-          That is, if the :paramref:`~.relationship.primaryjoin`
-          condition of this :func:`.relationship` is ``a.id ==
-          b.a_id``, and the values in ``b.a_id`` are required to be
-          present in ``a.id``, then the "foreign key" column of this
-          :func:`.relationship` is ``b.a_id``.
-
-          In normal cases, the :paramref:`~.relationship.foreign_keys`
-          parameter is **not required.** :func:`.relationship` will
-          automatically determine which columns in the
-          :paramref:`~.relationship.primaryjoin` conditition are to be
-          considered "foreign key" columns based on those
-          :class:`.Column` objects that specify :class:`.ForeignKey`,
-          or are otherwise listed as referencing columns in a
-          :class:`.ForeignKeyConstraint` construct.
-          :paramref:`~.relationship.foreign_keys` is only needed when:
-
-            1. There is more than one way to construct a join from the local
-               table to the remote table, as there are multiple foreign key
-               references present.  Setting ``foreign_keys`` will limit the
-               :func:`.relationship` to consider just those columns specified
-               here as "foreign".
-
-               .. versionchanged:: 0.8
-                    A multiple-foreign key join ambiguity can be resolved by
-                    setting the :paramref:`~.relationship.foreign_keys` parameter alone, without the
-                    need to explicitly set :paramref:`~.relationship.primaryjoin` as well.
-
-            2. The :class:`.Table` being mapped does not actually have
-               :class:`.ForeignKey` or :class:`.ForeignKeyConstraint`
-               constructs present, often because the table
-               was reflected from a database that does not support foreign key
-               reflection (MySQL MyISAM).
-
-            3. The :paramref:`~.relationship.primaryjoin` argument is used to construct a non-standard
-               join condition, which makes use of columns or expressions that do
-               not normally refer to their "parent" column, such as a join condition
-               expressed by a complex comparison using a SQL function.
-
-          The :func:`.relationship` construct will raise informative
-          error messages that suggest the use of the
-          :paramref:`~.relationship.foreign_keys` parameter when
-          presented with an ambiguous condition.   In typical cases,
-          if :func:`.relationship` doesn't raise any exceptions, the
-          :paramref:`~.relationship.foreign_keys` parameter is usually
-          not needed.

-        :param innerjoin=False:
-          when ``True``, joined eager loads will use an inner join to join
-          against related tables instead of an outer join.  The purpose
-          of this option is generally one of performance, as inner joins
-          generally perform better than outer joins.
-
-          This flag can be set to ``True`` when the relationship references an
-          object via many-to-one using local foreign keys that are not nullable,
-          or when the reference is one-to-one or a collection that is guaranteed
-          to have one or at least one entry.
-
-          If the joined-eager load is chained onto an existing LEFT OUTER JOIN,
-          ``innerjoin=True`` will be bypassed and the join will continue to
-          chain as LEFT OUTER JOIN so that the results don't change.  As an alternative,
-          specify the value ``"nested"``.  This will instead nest the join
-          on the right side, e.g. using the form "a LEFT OUTER JOIN (b JOIN c)".

-
-        :param lazy='select': specifies
-          how the related items should be loaded.  Default value is
-          ``select``.  Values include:
-
-          * ``select`` - items should be loaded lazily when the property is first
-            accessed, using a separate SELECT statement, or identity map
-            fetch for simple many-to-one references.
-
-          * ``immediate`` - items should be loaded as the parents are loaded,
-            using a separate SELECT statement, or identity map fetch for
-            simple many-to-one references.
-
-          * ``joined`` - items should be loaded "eagerly" in the same query as
-            that of the parent, using a JOIN or LEFT OUTER JOIN.  Whether
-            the join is "outer" or not is determined by the
-            :paramref:`~.relationship.innerjoin` parameter.
-
-          * ``subquery`` - items should be loaded "eagerly" as the parents are
-            loaded, using one additional SQL statement, which issues a JOIN to a
-            subquery of the original statement, for each collection requested.
-
-          * ``noload`` - no loading should occur at any time.  This is to
-            support "write-only" attributes, or attributes which are
-            populated in some manner specific to the application.
-
-          * ``dynamic`` - the attribute will return a pre-configured
-            :class:`.Query` object for all read
-            operations, onto which further filtering operations can be
-            applied before iterating the results.  See

-
-        :param load_on_pending=False:
-          Indicates loading behavior for transient or pending parent objects.
-
-          When set to ``True``, causes the lazy-loader to
-          issue a query for a parent object that is not persistent, meaning it has
-          never been flushed.  This may take effect for a pending object when
-          autoflush is disabled, or for a transient object that has been
-          "attached" to a :class:`.Session` but is not part of its pending
-          collection.
-
-          The :paramref:`~.relationship.load_on_pending` flag does not improve behavior
-          when the ORM is used normally - object references should be constructed
-          at the object level, not at the foreign key level, so that they
-          are present in an ordinary way before a flush proceeds.  This flag
-          is not not intended for general use.

-          .. seealso::
-
-              :meth:`.Session.enable_relationship_loading` - this method establishes
-              "load on pending" behavior for the whole object, and also allows
-              loading on objects that remain transient or detached.
-
-        :param order_by:
-          indicates the ordering that should be applied when loading these
-          items.  :paramref:`~.relationship.order_by` is expected to refer to one
-          of the :class:`.Column`
-          objects to which the target class is mapped, or
-          the attribute itself bound to the target class which refers
-          to the column.
-
-          :paramref:`~.relationship.order_by` may also be passed as a callable function
-          which is evaluated at mapper initialization time, and may be passed as a
-          Python-evaluable string when using Declarative.
-
-        :param passive_deletes=False:
-           Indicates loading behavior during delete operations.
-
-           A value of True indicates that unloaded child items should not
-           be loaded during a delete operation on the parent.  Normally,
-           when a parent item is deleted, all child items are loaded so
-           that they can either be marked as deleted, or have their
-           foreign key to the parent set to NULL.  Marking this flag as
-           True usually implies an ON DELETE <CASCADE|SET NULL> rule is in
-           place which will handle updating/deleting child rows on the
-           database side.
-
-           Additionally, setting the flag to the string value 'all' will
-           disable the "nulling out" of the child foreign keys, when there
-           is no delete or delete-orphan cascade enabled.  This is
-           typically used when a triggering or error raise scenario is in
-           place on the database side.  Note that the foreign key
-           attributes on in-session child objects will not be changed
-           after a flush occurs so this is a very special use-case
-           setting.

-           .. seealso::

-
-        :param passive_updates=True:
-          Indicates loading and INSERT/UPDATE/DELETE behavior when the
-          source of a foreign key value changes (i.e. an "on update"
-          cascade), which are typically the primary key columns of the
-          source row.
-
-          When True, it is assumed that ON UPDATE CASCADE is configured on
-          the foreign key in the database, and that the database will
-          handle propagation of an UPDATE from a source column to
-          dependent rows.  Note that with databases which enforce
-          referential integrity (i.e. PostgreSQL, MySQL with InnoDB tables),
-          ON UPDATE CASCADE is required for this operation.  The
-          relationship() will update the value of the attribute on related
-          items which are locally present in the session during a flush.
-
-          When False, it is assumed that the database does not enforce
-          referential integrity and will not be issuing its own CASCADE
-          operation for an update.  The relationship() will issue the
-          appropriate UPDATE statements to the database in response to the
-          change of a referenced key, and items locally present in the
-          session during a flush will also be refreshed.
-
-          This flag should probably be set to False if primary key changes
-          are expected and the database in use doesn't support CASCADE
-          (i.e. SQLite, MySQL MyISAM tables).

-              takes effect for joined-table inheritance mappings.
-
-        :param post_update:
-          this indicates that the relationship should be handled by a
-          second UPDATE statement after an INSERT or before a
-          DELETE. Currently, it also will issue an UPDATE after the
-          instance was UPDATEd as well, although this technically should
-          be improved. This flag is used to handle saving bi-directional
-          dependencies between two individual rows (i.e. each row
-          references the other), where it would otherwise be impossible to
-          INSERT or DELETE both rows fully since one row exists before the
-          other. Use this flag when a particular mapping arrangement will
-          incur two rows that are dependent on each other, such as a table
-          that has a one-to-many relationship to a set of child rows, and
-          also has a column that references a single child row within that
-          list (i.e. both tables contain a foreign key to each other). If
-          a flush operation returns an error that a "cyclical
-          dependency" was detected, this is a cue that you might want to
-          use :paramref:`~.relationship.post_update` to "break" the cycle.

-            In a many-to-one context, such as::
-
-              MyClass.some_prop != <some object>
-
-            This will typically produce a clause such as::
-
-              mytable.related_id != <some id>
-
-            Where ``<some id>`` is the primary key of the
-            given object.
-
-            The ``!=`` operator provides partial functionality for non-
-            many-to-one comparisons:
-
-            * Comparisons against collections are not supported.
-              Use
-              :meth:`~.RelationshipProperty.Comparator.contains`
-              in conjunction with :func:`~.expression.not_`.
-            * Compared to a scalar one-to-many, will produce a
-              clause that compares the target columns in the parent to
-              the given target.
-            * Compared to a scalar many-to-many, an alias
-              of the association table will be rendered as
-              well, forming a natural join that is part of the
-              main body of the query. This will not work for
-              queries that go beyond simple AND conjunctions of
-              comparisons, such as those which use OR. Use
-              explicit joins, outerjoins, or
-              :meth:`~.RelationshipProperty.Comparator.has` in
-              conjunction with :func:`~.expression.not_` for
-              more comprehensive non-many-to-one scalar
-              membership tests.
-            * Comparisons against ``None`` given in a one-to-many
-              or many-to-many context produce an EXISTS clause.

-class SessionTransaction(object):
-    """A :class:`.Session`-level transaction.
-
-    :class:`.SessionTransaction` is a mostly behind-the-scenes object
-    not normally referenced directly by application code.   It coordinates
-    among multiple :class:`.Connection` objects, maintaining a database
-    transaction for each one individually, committing or rolling them
-    back all at once.   It also provides optional two-phase commit behavior
-    which can augment this coordination operation.
-
-    The :attr:`.Session.transaction` attribute of :class:`.Session`
-    refers to the current :class:`.SessionTransaction` object in use, if any.
-
-
-    A :class:`.SessionTransaction` is associated with a :class:`.Session`
-    in its default mode of ``autocommit=False`` immediately, associated
-    with no database connections.  As the :class:`.Session` is called upon
-    to emit SQL on behalf of various :class:`.Engine` or :class:`.Connection`
-    objects, a corresponding :class:`.Connection` and associated
-    :class:`.Transaction` is added to a collection within the
-    :class:`.SessionTransaction` object, becoming one of the
-    connection/transaction pairs maintained by the
-    :class:`.SessionTransaction`.
-
-    The lifespan of the :class:`.SessionTransaction` ends when the
-    :meth:`.Session.commit`, :meth:`.Session.rollback` or
-    :meth:`.Session.close` methods are called.  At this point, the
-    :class:`.SessionTransaction` removes its association with its parent
-    :class:`.Session`.   A :class:`.Session` that is in ``autocommit=False``
-    mode will create a new :class:`.SessionTransaction` to replace it
-    immediately, whereas a :class:`.Session` that's in ``autocommit=True``
-    mode will remain without a :class:`.SessionTransaction` until the
-    :meth:`.Session.begin` method is called.
-
-    Another detail of :class:`.SessionTransaction` behavior is that it is
-    capable of "nesting".  This means that the :meth:`.Session.begin` method
-    can be called while an existing :class:`.SessionTransaction` is already
-    present, producing a new :class:`.SessionTransaction` that temporarily
-    replaces the parent :class:`.SessionTransaction`.   When a
-    :class:`.SessionTransaction` is produced as nested, it assigns itself to
-    the :attr:`.Session.transaction` attribute.  When it is ended via
-    :meth:`.Session.commit` or :meth:`.Session.rollback`, it restores its
-    parent :class:`.SessionTransaction` back onto the
-    :attr:`.Session.transaction` attribute.  The behavior is effectively a
-    stack, where :attr:`.Session.transaction` refers to the current head of
-    the stack.
-
-    The purpose of this stack is to allow nesting of
-    :meth:`.Session.rollback` or :meth:`.Session.commit` calls in context
-    with various flavors of :meth:`.Session.begin`. This nesting behavior
-    applies to when :meth:`.Session.begin_nested` is used to emit a
-    SAVEPOINT transaction, and is also used to produce a so-called
-    "subtransaction" which allows a block of code to use a
-    begin/rollback/commit sequence regardless of whether or not its enclosing
-    code block has begun a transaction.  The :meth:`.flush` method, whether
-    called explicitly or via autoflush, is the primary consumer of the
-    "subtransaction" feature, in that it wishes to guarantee that it works
-    within in a transaction block regardless of whether or not the
-    :class:`.Session` is in transactional mode when the method is called.

-        set of arguments.
-
-        :param autocommit:
-
-          .. warning::
-
-             The autocommit flag is **not for general use**, and if it is used,
-             queries should only be invoked within the span of a
-             :meth:`.Session.begin` / :meth:`.Session.commit` pair.   Executing
-             queries outside of a demarcated transaction is a legacy mode
-             of usage, and can in some cases lead to concurrent connection
-             checkouts.
-
-          Defaults to ``False``. When ``True``, the
-          :class:`.Session` does not keep a persistent transaction running, and
-          will acquire connections from the engine on an as-needed basis,
-          returning them immediately after their use. Flushes will begin and
-          commit (or possibly rollback) their own transaction if no
-          transaction is present. When using this mode, the
-          :meth:`.Session.begin` method is used to explicitly start
-          transactions.
-
-          .. seealso::
-
-            :ref:`session_autocommit`
-
-        :param autoflush: When ``True``, all query operations will issue a
-           ``flush()`` call to this ``Session`` before proceeding. This is a
-           convenience feature so that ``flush()`` need not be called
-           repeatedly in order for database queries to retrieve results. It's
-           typical that ``autoflush`` is used in conjunction with
-           ``autocommit=False``. In this scenario, explicit calls to
-           ``flush()`` are rarely needed; you usually only need to call
-           ``commit()`` (which flushes) to finalize changes.
-
-        :param bind: An optional ``Engine`` or ``Connection`` to which this
-           ``Session`` should be bound. When specified, all SQL operations
-           performed by this session will execute via this connectable.
-
-        :param binds: An optional dictionary which contains more granular
-           "bind" information than the ``bind`` parameter provides. This
-           dictionary can map individual ``Table`` instances as well as
-           ``Mapper`` instances to individual ``Engine`` or ``Connection``
-           objects. Operations which proceed relative to a particular
-           ``Mapper`` will consult this dictionary for the direct ``Mapper``
-           instance as well as the mapper's ``mapped_table`` attribute in
-           order to locate an connectable to use. The full resolution is
-           described in the ``get_bind()`` method of ``Session``.
-           Usage looks like::
-
-            Session = sessionmaker(binds={
-                SomeMappedClass: create_engine('postgresql://engine1'),
-                somemapper: create_engine('postgresql://engine2'),
-                some_table: create_engine('postgresql://engine3'),
-                })
-
-          Also see the :meth:`.Session.bind_mapper`
-          and :meth:`.Session.bind_table` methods.
-
-        :param \class_: Specify an alternate class other than
-           ``sqlalchemy.orm.session.Session`` which should be used by the
-           returned class. This is the only argument that is local to the
-           ``sessionmaker()`` function, and is not sent directly to the
-           constructor for ``Session``.
-
-        :param _enable_transaction_accounting:  Defaults to ``True``.  A
-           legacy-only flag which when ``False`` disables *all* 0.5-style
-           object accounting on transaction boundaries, including auto-expiry
-           of instances on rollback and commit, maintenance of the "new" and
-           "deleted" lists upon rollback, and autoflush of pending changes upon
-           begin(), all of which are interdependent.
-
-        :param expire_on_commit:  Defaults to ``True``. When ``True``, all
-           instances will be fully expired after each ``commit()``, so that
-           all attribute/object access subsequent to a completed transaction
-           will load from the most recent database state.
-
-        :param extension: An optional
-           :class:`~.SessionExtension` instance, or a list
-           of such instances, which will receive pre- and post- commit and
-           flush events, as well as a post-rollback event. **Deprecated.**
-           Please see :class:`.SessionEvents`.
-
-        :param info: optional dictionary of arbitrary data to be associated
-           with this :class:`.Session`.  Is available via the :attr:`.Session.info`
-           attribute.  Note the dictionary is copied at construction time so
-           that modifications to the per-:class:`.Session` dictionary will be local
-           to that :class:`.Session`.
-
-           .. versionadded:: 0.9.0
-
-        :param query_cls:  Class which should be used to create new Query
-           objects, as returned by the ``query()`` method. Defaults to
-           :class:`~sqlalchemy.orm.query.Query`.
-
-        :param twophase:  When ``True``, all transactions will be started as
-            a "two phase" transaction, i.e. using the "two phase" semantics
-            of the database in use along with an XID.  During a ``commit()``,
-            after ``flush()`` has been issued for all attached databases, the
-            ``prepare()`` method on each database's ``TwoPhaseTransaction``
-            will be called. This allows each database to roll back the entire
-            transaction, before each transaction is committed.
-
-        :param weak_identity_map:  Defaults to ``True`` - when set to
-           ``False``, objects placed in the :class:`.Session` will be
-           strongly referenced until explicitly removed or the
-           :class:`.Session` is closed.  **Deprecated** - this option
-           is obsolete.

-        :func:`~.sql.expression.update`,
-        :func:`~.sql.expression.delete`, and

-        will be interpreted the same as if it were passed via a
-        :func:`~.expression.text` construct.  That is, the following usage::
-
-            result = session.execute(
-                        "SELECT * FROM user WHERE id=:param",
-                        {"param":5}
-                    )
-
-        is equivalent to::
-
-            from sqlalchemy import text
-            result = session.execute(
-                        text("SELECT * FROM user WHERE id=:param"),
-                        {"param":5}
-                    )
-
-        The second positional argument to :meth:`.Session.execute` is an
-        optional parameter set.  Similar to that of
-        :meth:`.Connection.execute`, whether this is passed as a single
-        dictionary, or a list of dictionaries, determines whether the DBAPI
-        cursor's ``execute()`` or ``executemany()`` is used to execute the
-        statement.   An INSERT construct may be invoked for a single row::
-
-            result = session.execute(users.insert(), {"id": 7, "name": "somename"})
-
-        or for multiple rows::
-
-            result = session.execute(users.insert(), [
-                                    {"id": 7, "name": "somename7"},
-                                    {"id": 8, "name": "somename8"},
-                                    {"id": 9, "name": "somename9"}
-                                ])
-
-        The statement is executed within the current transactional context of
-        this :class:`.Session`.   The :class:`.Connection` which is used
-        to execute the statement can also be acquired directly by
-        calling the :meth:`.Session.connection` method.  Both methods use
-        a rule-based resolution scheme in order to determine the
-        :class:`.Connection`, which in the average case is derived directly
-        from the "bind" of the :class:`.Session` itself, and in other cases
-        can be based on the :func:`.mapper`
-        and :class:`.Table` objects passed to the method; see the documentation
-        for :meth:`.Session.get_bind` for a full description of this scheme.
-
-        The :meth:`.Session.execute` method does *not* invoke autoflush.
-
-        The :class:`.ResultProxy` returned by the :meth:`.Session.execute`
-        method is returned with the "close_with_result" flag set to true;
-        the significance of this flag is that if this :class:`.Session` is
-        autocommitting and does not have a transaction-dedicated
-        :class:`.Connection` available, a temporary :class:`.Connection` is
-        established for the statement execution, which is closed (meaning,
-        returned to the connection pool) when the :class:`.ResultProxy` has
-        consumed all available data. This applies *only* when the
-        :class:`.Session` is configured with autocommit=True and no
-        transaction has been started.

-
-        :param params:

-            bound parameter values.   If a single dictionary, single-row
-            execution occurs; if a list of dictionaries, an
-            "executemany" will be invoked.  The keys in each dictionary
-            must correspond to parameter names present in the statement.
-
-        :param mapper:
-          Optional :func:`.mapper` or mapped class, used to identify
-          the appropriate bind.  This argument takes precedence over

-          for more details.
-

-         events, and without the need to reconcile the incoming data with
-         any existing related objects or collections that might not
-         be loaded.  The resulting objects from ``load=False`` are always
-         produced as "clean", so it is only appropriate that the given objects
-         should be "clean" as well, else this suggests a mis-use of the method.

-            use cases and is not recommended for general use.
-
-        Accesses of attributes mapped with :func:`.relationship`
-        will attempt to load a value from the database using this
-        :class:`.Session` as the source of connectivity.  The values
-        will be loaded based on foreign key values present on this
-        object - it follows that this functionality
-        generally only works for many-to-one-relationships.
-
-        The object will be attached to this session, but will
-        **not** participate in any persistence operations; its state
-        for almost all purposes will remain either "transient" or
-        "detached", except for the case of relationship loading.
-
-        Also note that backrefs will often not work as expected.
-        Altering a relationship-bound attribute on the target object
-        may not fire off a backref event, if the effective value
-        is what was already loaded from a foreign-key-holding value.
-
-        The :meth:`.Session.enable_relationship_loading` method is
-        similar to the ``load_on_pending`` flag on :func:`.relationship`.   Unlike
-        that flag, :meth:`.Session.enable_relationship_loading` allows
-        an object to remain transient while still being able to load
-        related items.
-
-        To make a transient object associated with a :class:`.Session`
-        via :meth:`.Session.enable_relationship_loading` pending, add
-        it to the :class:`.Session` using :meth:`.Session.add` normally.
-
-        :meth:`.Session.enable_relationship_loading` does not improve
-        behavior when the ORM is used normally - object references should be
-        constructed at the object level, not at the foreign key level, so
-        that they are present in an ordinary way before flush()

-        This method retrieves the history for each instrumented

-        value to its previously committed value, if any.
-
-        It is in effect a more expensive and accurate
-        version of checking for the given instance in the
-        :attr:`.Session.dirty` collection; a full test for
-        each attribute's net "dirty" status is performed.
-
-        E.g.::
-
-            return session.is_modified(someobject)
-
-        .. versionchanged:: 0.8
-            When using SQLAlchemy 0.7 and earlier, the ``passive``
-            flag should **always** be explicitly set to ``True``,
-            else SQL loads/autoflushes may proceed which can affect
-            the modified state itself:
-            ``session.is_modified(someobject, passive=True)``\ .
-            In 0.8 and above, the behavior is corrected and
-            this flag is ignored.
-
-        A few caveats to this method apply:
-
-        * Instances present in the :attr:`.Session.dirty` collection may report
-          ``False`` when tested with this method.  This is because
-          the object may have received change events via attribute
-          mutation, thus placing it in :attr:`.Session.dirty`,
-          but ultimately the state is the same as that loaded from
-          the database, resulting in no net change here.
-        * Scalar attributes may not have recorded the previously set
-          value when a new value was applied, if the attribute was not loaded,
-          or was expired, at the time the new value was received - in these
-          cases, the attribute is assumed to have a change, even if there is
-          ultimately no net change against its database value. SQLAlchemy in
-          most cases does not need the "old" value when a set event occurs, so
-          it skips the expense of a SQL call if the old value isn't present,
-          based on the assumption that an UPDATE of the scalar value is
-          usually needed, and in those few cases where it isn't, is less
-          expensive on average than issuing a defensive SELECT.
-
-          The "old" value is fetched unconditionally upon set only if the
-          attribute container has the ``active_history`` flag set to ``True``.
-          This flag is set typically for primary key attributes and scalar
-          object references that are not a simple many-to-one.  To set this
-          flag for any arbitrary mapped column, use the ``active_history``
-          argument with :func:`.column_property`.
-
-        :param instance: mapped instance to be tested for pending changes.
-        :param include_collections: Indicates if multivalued collections
-         should be included in the operation.  Setting this to ``False`` is a
-         way to detect only local-column based properties (i.e. scalar columns
-         or many-to-one foreign keys) that would result in an UPDATE for this
-         instance upon flush.
-        :param passive:
-         .. versionchanged:: 0.8
-             Ignored for backwards compatibility.
-             When using SQLAlchemy 0.7 and earlier, this flag should always

-        """True if this :class:`.Session` is in "transaction mode" and
-        is not in "partial rollback" state.
-
-        The :class:`.Session` in its default mode of ``autocommit=False``
-        is essentially always in "transaction mode", in that a
-        :class:`.SessionTransaction` is associated with it as soon as
-        it is instantiated.  This :class:`.SessionTransaction` is immediately
-        replaced with a new one as soon as it is ended, due to a rollback,
-        commit, or close operation.
-
-        "Transaction mode" does *not* indicate whether
-        or not actual database connection resources are in use;  the
-        :class:`.SessionTransaction` object coordinates among zero or more
-        actual database transactions, and starts out with none, accumulating
-        individual DBAPI connections as different data sources are used
-        within its scope.   The best way to track when a particular
-        :class:`.Session` has actually begun to use DBAPI resources is to
-        implement a listener using the :meth:`.SessionEvents.after_begin`
-        method, which will deliver both the :class:`.Session` as well as the
-        target :class:`.Connection` to a user-defined event listener.
-
-        The "partial rollback" state refers to when an "inner" transaction,
-        typically used during a flush, encounters an error and emits a
-        rollback of the DBAPI connection.  At this point, the
-        :class:`.Session` is in "partial rollback" and awaits for the user to
-        call :meth:`.Session.rollback`, in order to close out the
-        transaction stack.  It is in this "partial rollback" period that the
-        :attr:`.is_active` flag returns False.  After the call to
-        :meth:`.Session.rollback`, the :class:`.SessionTransaction` is replaced
-        with a new one and :attr:`.is_active` returns ``True`` again.
-
-        When a :class:`.Session` is used in ``autocommit=True`` mode, the
-        :class:`.SessionTransaction` is only instantiated within the scope
-        of a flush call, or when :meth:`.Session.begin` is called.  So
-        :attr:`.is_active` will always be ``False`` outside of a flush or
-        :meth:`.Session.begin` block in this mode, and will be ``True``
-        within the :meth:`.Session.begin` block as long as it doesn't enter
-        "partial rollback" state.
-
-        From all the above, it follows that the only purpose to this flag is
-        for application frameworks that wish to detect is a "rollback" is
-        necessary within a generic error handling routine, for
-        :class:`.Session` objects that would otherwise be in
-        "partial rollback" mode.  In a typical integration case, this is also
-        not necessary as it is standard practice to emit
-        :meth:`.Session.rollback` unconditionally within the outermost
-        exception catch.
-
-        To track the transactional state of a :class:`.Session` fully,
-        use event listeners, primarily the :meth:`.SessionEvents.after_begin`,
-        :meth:`.SessionEvents.after_commit`,
-        :meth:`.SessionEvents.after_rollback` and related events.

-class Load(Generative, MapperOption):
-    """Represents loader options which modify the state of a
-    :class:`.Query` in order to affect how various mapped attributes are loaded.
-
-    .. versionadded:: 0.9.0 The :meth:`.Load` system is a new foundation for
-       the existing system of loader options, including options such as
-       :func:`.orm.joinedload`, :func:`.orm.defer`, and others.   In particular,
-       it introduces a new method-chained system that replaces the need for
-       dot-separated paths as well as "_all()" options such as :func:`.orm.joinedload_all`.
-
-    A :class:`.Load` object can be used directly or indirectly.  To use one
-    directly, instantiate given the parent class.  This style of usage is
-    useful when dealing with a :class:`.Query` that has multiple entities,
-    or when producing a loader option that can be applied generically to
-    any style of query::
-
-        myopt = Load(MyClass).joinedload("widgets")
-
-    The above ``myopt`` can now be used with :meth:`.Query.options`::
-
-        session.query(MyClass).options(myopt)
-
-    The :class:`.Load` construct is invoked indirectly whenever one makes use
-    of the various loader options that are present in ``sqlalchemy.orm``, including
-    options such as :func:`.orm.joinedload`, :func:`.orm.defer`, :func:`.orm.subqueryload`,
-    and all the rest.  These constructs produce an "anonymous" form of the
-    :class:`.Load` object which tracks attributes and options, but is not linked
-    to a parent class until it is associated with a parent :class:`.Query`::
-
-        # produce "unbound" Load object
-        myopt = joinedload("widgets")
-
-        # when applied using options(), the option is "bound" to the
-        # class observed in the given query, e.g. MyClass
-        session.query(MyClass).options(myopt)
-
-    Whether the direct or indirect style is used, the :class:`.Load` object
-    returned now represents a specific "path" along the entities of a :class:`.Query`.
-    This path can be traversed using a standard method-chaining approach.
-    Supposing a class hierarchy such as ``User``, ``User.addresses -> Address``,
-    ``User.orders -> Order`` and ``Order.items -> Item``, we can specify a variety
-    of loader options along each element in the "path"::
-
-        session.query(User).options(
-                    joinedload("addresses"),
-                    subqueryload("orders").joinedload("items")
-                )
-
-    Where above, the ``addresses`` collection will be joined-loaded, the
-    ``orders`` collection will be subquery-loaded, and within that subquery load
-    the ``items`` collection will be joined-loaded.

-

-      :param ident: primary key, may be a scalar or tuple argument.
-
-
-    * ``identity_key(instance=instance)``
-
-      This form will produce the identity key for a given instance.  The
-      instance need not be persistent, only that its primary key attributes
-      are populated (else the key will contain ``None`` for those missing

-        >>> instance = MyClass(1, 2)
-        >>> identity_key(instance=instance)
-        (<class '__main__.MyClass'>, (1, 2))

-      :meth:`.Mapper.identity_key_from_instance`, which will have the

-
-    Usage is via the :func:`.orm.aliased` function, or alternatively
-    via the :func:`.orm.with_polymorphic` function.
-
-    Usage example::
-
-        # find all pairs of users with the same name
-        user_alias = aliased(User)
-        session.query(User, user_alias).\\

-
-    The resulting object is an instance of :class:`.AliasedClass`.
-    This object implements an attribute scheme which produces the
-    same attribute and method interface as the original mapped
-    class, allowing :class:`.AliasedClass` to be compatible
-    with any attribute technique which works on the original class,
-    including hybrid attributes (see :ref:`hybrids_toplevel`).
-
-    The :class:`.AliasedClass` can be inspected for its underlying
-    :class:`.Mapper`, aliased selectable, and other information
-    using :func:`.inspect`::
-
-        from sqlalchemy import inspect
-        my_alias = aliased(MyClass)
-        insp = inspect(my_alias)
-
-    The resulting inspection object is an instance of :class:`.AliasedInsp`.

-
-    The :func:`.aliased` function is used to create an ad-hoc mapping
-    of a mapped class to a new selectable.  By default, a selectable
-    is generated from the normally mapped selectable (typically a
-    :class:`.Table`) using the :meth:`.FromClause.alias` method.
-    However, :func:`.aliased` can also be used to link the class to
-    a new :func:`.select` statement.   Also, the :func:`.with_polymorphic`
-    function is a variant of :func:`.aliased` that is intended to specify
-    a so-called "polymorphic selectable", that corresponds to the union
-    of several joined-inheritance subclasses at once.
-
-    For convenience, the :func:`.aliased` function also accepts plain
-    :class:`.FromClause` constructs, such as a :class:`.Table` or
-    :func:`.select` construct.   In those cases, the :meth:`.FromClause.alias`
-    method is called on the object and the new :class:`.Alias` object
-    returned.  The returned :class:`.Alias` is not ORM-mapped in this case.
-
-    :param element: element to be aliased.  Is normally a mapped class,
-     but for convenience can also be a :class:`.FromClause` element.
-
-    :param alias: Optional selectable unit to map the element to.  This should
-     normally be a :class:`.Alias` object corresponding to the :class:`.Table`
-     to which the class is mapped, or to a :func:`.select` construct that
-     is compatible with the mapping.   By default, a simple anonymous
-     alias of the mapped table is generated.
-
-    :param name: optional string name to use for the alias, if not specified
-     by the ``alias`` parameter.  The name, among other things, forms the
-     attribute name that will be accessible via tuples returned by a
-     :class:`.Query` object.
-
-    :param flat: Boolean, will be passed through to the :meth:`.FromClause.alias`
-     call so that aliases of :class:`.Join` objects don't include an enclosing
-     SELECT.  This can lead to more efficient queries in many circumstances.

-    left and right selectables may be not only core selectable
-    objects such as :class:`.Table`, but also mapped classes or
-    :class:`.AliasedClass` instances.   The "on" clause can
-    be a SQL expression, or an attribute or string name
-    referencing a configured :func:`.relationship`.
-
-    :func:`.orm.join` is not commonly needed in modern usage,
-    as its functionality is encapsulated within that of the
-    :meth:`.Query.join` method, which features a
-    significant amount of automation beyond :func:`.orm.join`
-    by itself.  Explicit usage of :func:`.orm.join`
-    with :class:`.Query` involves usage of the
-    :meth:`.Query.select_from` method, as in::
-
-        from sqlalchemy.orm import join
-        session.query(User).\\
-            select_from(join(User, Address, User.addresses)).\\
-            filter(Address.email_address=='foo@bar.com')
-
-    In modern SQLAlchemy the above join can be written more
-    succinctly as::
-
-        session.query(User).\\
-                join(User.addresses).\\
-                filter(Address.email_address=='foo@bar.com')
-
-    See :meth:`.Query.join` for information on modern usage
-    of ORM level joins.

-            This is the default value.  The vast majority
-            of use cases should leave this value set.
-          * ``True`` - same as 'rollback', this is here for
-            backwards compatibility.
-          * ``"commit"`` - call commit() on the connection,
-            to release locks and transaction resources.
-            A commit here may be desirable for databases that
-            cache query plans if a commit is emitted,
-            such as Microsoft SQL Server.  However, this
-            value is more dangerous than 'rollback' because
-            any data changes present on the transaction
-            are committed unconditionally.
-          * ``None`` - don't do anything on the connection.
-            This setting should only be made on a database
-            that has no transaction support at all,
-            namely MySQL MyISAM.   By not doing anything,

-            database that supports transactions,
-            as it will lead to deadlocks and stale
-            state.

-
-    Typical integration is to examine the incoming :class:`.Column`
-    object, and to redirect compilation if a particular flag or condition
-    is found::
-
-        from sqlalchemy import schema
-        from sqlalchemy.ext.compiler import compiles

-                )
-            default = compiler.get_column_default_string(column)
-            if default is not None:

-                            for const in column.constraints)
-            return text
-
-    The above construct can be applied to a :class:`.Table` as follows::
-
-        from sqlalchemy import Table, Metadata, Column, Integer, String
-        from sqlalchemy import schema
-
-        metadata = MetaData()
-
-        table = Table('mytable', MetaData(),
-                Column('x', Integer, info={"special":True}, primary_key=True),
-                Column('y', String(50)),
-                Column('z', String(20), info={"special":True})
-            )
-
-        metadata.create_all(conn)
-
-    Above, the directives we've added to the :attr:`.Column.info` collection
-    will be detected by our custom compilation scheme::
-
-        CREATE TABLE mytable (
-                x SPECIAL DIRECTIVE INTEGER NOT NULL,
-                y VARCHAR(50),
-                z SPECIAL DIRECTIVE VARCHAR(20),
-            PRIMARY KEY (x)
-        )
-
-    The :class:`.CreateColumn` construct can also be used to skip certain
-    columns when producing a ``CREATE TABLE``.  This is accomplished by
-    creating a compilation rule that conditionally returns ``None``.
-    This is essentially how to produce the same effect as using the
-    ``system=True`` argument on :class:`.Column`, which marks a column
-    as an implicitly-present "system" column.
-
-    For example, suppose we wish to produce a :class:`.Table` which skips
-    rendering of the Postgresql ``xmin`` column against the Postgresql backend,
-    but on other backends does render it, in anticipation of a triggered rule.
-    A conditional compilation rule could skip this name only on Postgresql::
-
-        from sqlalchemy.schema import CreateColumn
-
-        @compiles(CreateColumn, "postgresql")
-        def skip_xmin(element, compiler, **kw):
-            if element.element.name == 'xmin':
-                return None
-            else:
-                return compiler.visit_create_column(element, **kw)
-
-
-        my_table = Table('mytable', metadata,
-                    Column('id', Integer, primary_key=True),
-                    Column('xmin', Integer)
-                )
-
-    Above, a :class:`.CreateTable` construct will generate a ``CREATE TABLE``
-    which only includes the ``id`` column in the string; the ``xmin`` column
-    will be omitted, but only against the Postgresql backend.
-
-    .. versionadded:: 0.8.3 The :class:`.CreateColumn` construct supports
-       skipping of columns by returning ``None`` from a custom compilation rule.
-
-    .. versionadded:: 0.8 The :class:`.CreateColumn` construct was added

-
-        Multiple calls to :meth:`.ValuesBase.values` will produce a new
-        construct, each one with the parameter list modified to include
-        the new parameters sent.  In the typical case of a single

-
-         The :class:`.Insert` construct also supports multiply-rendered VALUES
-         construct, for those backends which support this SQL syntax
-         (SQLite, Postgresql, MySQL).  This mode is indicated by passing a list
-         of one or more dictionaries/tuples::
-
-            users.insert().values([
-                                {"name": "some name"},

-
-         In the case of an :class:`.Update`
-         construct, only the single dictionary/tuple form is accepted,
-         else an exception is raised.  It is also an exception case to
-         attempt to mix the single-/multiple- value styles together,
-         either through multiple :meth:`.ValuesBase.values` calls
-         or by sending a list + kwargs at the same time.
-
-         .. note::
-
-             Passing a multiple values list is *not* the same
-             as passing a multiple values list to the :meth:`.Connection.execute`
-             method.  Passing a list of parameter sets to :meth:`.ValuesBase.values`
-             produces a construct of this form::
-
-                INSERT INTO table (col1, col2, col3) VALUES
-                                (col1_0, col2_0, col3_0),

-                                ...
-
-             whereas a multiple list passed to :meth:`.Connection.execute`
-             has the effect of using the DBAPI
-             `executemany() <http://www.python.org/dev/peps/pep-0249/#id18>`_
-             method, which provides a high-performance system of invoking
-             a single-row INSERT statement many times against a series
-             of parameter sets.   The "executemany" style is supported by
-             all database backends, as it does not depend on a special SQL
-             syntax.

-        When used against a backend that supports RETURNING, all column

-        to any existing RETURNING clause, provided that
-        :meth:`.UpdateBase.returning` is not used simultaneously.   The column values
-        will then be available on the result using the
-        :attr:`.ResultProxy.returned_defaults` accessor as a
-        dictionary, referring to values keyed to the :class:`.Column` object
-        as well as its ``.key``.
-
-        This method differs from :meth:`.UpdateBase.returning` in these ways:
-
-        1. :meth:`.ValuesBase.return_defaults` is only intended for use with
-           an INSERT or an UPDATE statement that matches exactly one row.
-           While the RETURNING construct in the general sense supports multiple
-           rows for a multi-row UPDATE or DELETE statement, or for special
-           cases of INSERT that return multiple rows (e.g. INSERT from SELECT,
-           multi-valued VALUES clause), :meth:`.ValuesBase.return_defaults`
-           is intended only
-           for an "ORM-style" single-row INSERT/UPDATE statement.  The row
-           returned by the statement is also consumed implcitly when
-           :meth:`.ValuesBase.return_defaults` is used.  By contrast,
-           :meth:`.UpdateBase.returning` leaves the RETURNING result-set intact
-           with a collection of any number of rows.
-
-        2. It is compatible with the existing logic to fetch auto-generated
-           primary key values, also known as "implicit returning".  Backends that
-           support RETURNING will automatically make use of RETURNING in order
-           to fetch the value of newly generated primary keys; while the
-           :meth:`.UpdateBase.returning` method circumvents this behavior,
-           :meth:`.ValuesBase.return_defaults` leaves it intact.
-
-        3. It can be called against any backend.  Backends that don't support
-           RETURNING will skip the usage of the feature, rather than raising
-           an exception.  The return value of :attr:`.ResultProxy.returned_defaults`
-           will be ``None``
-
-        :meth:`.ValuesBase.return_defaults` is used by the ORM to provide
-        an efficient implementation for the ``eager_defaults`` feature of
-        :func:`.mapper`.

-        :class:`.Column`, normally but not necessarily equivalent to

-        :class:`.Column` objects used here are expected to be

-        to be updated.  However when using MySQL, a multiple-table
-        UPDATE statement can refer to columns from any of
-        the tables referred to in the WHERE clause.
-
-        The values referred to in ``values`` are typically:

-        * a literal data value (i.e. string, number, etc.)
-        * a SQL expression, such as a related :class:`.Column`,

-    """Represent a column-oriented SQL expression suitable for usage in the
-    "columns" clause, WHERE clause etc. of a statement.
-
-    While the most familiar kind of :class:`.ColumnElement` is the
-    :class:`.Column` object, :class:`.ColumnElement` serves as the basis
-    for any unit that may be present in a SQL expression, including
-    the expressions themselves, SQL functions, bound parameters,
-    literal expressions, keywords such as ``NULL``, etc.
-    :class:`.ColumnElement` is the ultimate base class for all such elements.
-
-    A wide variety of SQLAlchemy Core functions work at the SQL expression level,
-    and are intended to accept instances of :class:`.ColumnElement` as arguments.
-    These functions will typically document that they accept a "SQL expression"
-    as an argument.  What this means in terms of SQLAlchemy usually refers
-    to an input which is either already in the form of a :class:`.ColumnElement`
-    object, or a value which can be **coerced** into one.   The coercion
-    rules followed by most, but not all, SQLAlchemy Core functions with regards
-    to SQL expressions are as follows:
-
-        * a literal Python value, such as a string, integer or floating
-          point value, boolean, datetime, ``Decimal`` object, or virtually
-          any other Python object, will be coerced into a "literal bound value".
-          This generally means that a :func:`.bindparam` will be produced
-          featuring the given value embedded into the construct; the resulting
-          :class:`.BindParameter` object is an instance of :class:`.ColumnElement`.
-          The Python value will ultimately be sent to the DBAPI at execution time as a
-          paramterized argument to the ``execute()`` or ``executemany()`` methods,
-          after SQLAlchemy type-specific converters (e.g. those provided by
-          any associated :class:`.TypeEngine` objects) are applied to the value.
-
-        * any special object value, typically ORM-level constructs, which feature
-          a method called ``__clause_element__()``.   The Core expression system
-          looks for this method when an object of otherwise unknown type is passed
-          to a function that is looking to coerce the argument into a :class:`.ColumnElement`
-          expression.  The ``__clause_element__()`` method, if present, should
-          return a :class:`.ColumnElement` instance.  The primary use of
-          ``__clause_element__()`` within SQLAlchemy is that of class-bound attributes
-          on ORM-mapped classes; a ``User`` class which contains a mapped attribute
-          named ``.name`` will have a method ``User.name.__clause_element__()``
-          which when invoked returns the :class:`.Column` called ``name`` associated
-          with the mapped table.
-
-        * The Python ``None`` value is typically interpreted as ``NULL``, which
-          in SQLAlchemy Core produces an instance of :func:`.null`.
-
-    A :class:`.ColumnElement` provides the ability to generate new
-    :class:`.ColumnElement`
-    objects using Python expressions.  This means that Python operators
-    such as ``==``, ``!=`` and ``<`` are overloaded to mimic SQL operations,
-    and allow the instantiation of further :class:`.ColumnElement` instances
-    which are composed from other, more fundamental :class:`.ColumnElement`
-    objects.  For example, two :class:`.ColumnClause` objects can be added
-    together with the addition operator ``+`` to produce
-    a :class:`.BinaryExpression`.
-    Both :class:`.ColumnClause` and :class:`.BinaryExpression` are subclasses
-    of :class:`.ColumnElement`::
-
-        >>> from sqlalchemy.sql import column
-        >>> column('a') + column('b')
-        <sqlalchemy.sql.expression.BinaryExpression object at 0x101029dd0>

-
-        The return value is an instance of :class:`.BindParameter`; this
-        is a :class:`.ColumnElement` subclass which represents a so-called
-        "placeholder" value in a SQL expression, the value of which is supplied
-        at the point at which the statement in executed against a database
-        connection.
-
-        In SQLAlchemy, the :func:`.bindparam` construct has
-        the ability to carry along the actual value that will be ultimately
-        used at expression time.  In this way, it serves not just as
-        a "placeholder" for eventual population, but also as a means of
-        representing so-called "unsafe" values which should not be rendered
-        directly in a SQL statement, but rather should be passed along
-        to the :term:`DBAPI` as values which need to be correctly escaped
-        and potentially handled for type-safety.
-
-        When using :func:`.bindparam` explicitly, the use case is typically
-        one of traditional deferment of parameters; the :func:`.bindparam`
-        construct accepts a name which can then be referred to at execution
-        time::
-
-            from sqlalchemy import bindparam
-
-            stmt = select([users_table]).\\
-                        where(users_table.c.name == bindparam('username'))
-
-        The above statement, when rendered, will produce SQL similar to::
-
-            SELECT id, name FROM user WHERE name = :username
-
-        In order to populate the value of ``:username`` above, the value
-        would typically be applied at execution time to a method
-        like :meth:`.Connection.execute`::
-
-            result = connection.execute(stmt, username='wendy')
-
-        Explicit use of :func:`.bindparam` is also common when producing
-        UPDATE or DELETE statements that are to be invoked multiple times,
-        where the WHERE criterion of the statement is to change on each
-        invocation, such as::
-
-            stmt = users_table.update().\\
-                            where(user_table.c.name == bindparam('username')).\\
-                            values(fullname=bindparam('fullname'))
-
-            connection.execute(stmt, [
-                                {"username": "wendy", "fullname": "Wendy Smith"},
-                                {"username": "jack", "fullname": "Jack Jones"},
-                        ])
-
-        SQLAlchemy's Core expression system makes wide use of :func:`.bindparam`
-        in an implicit sense.   It is typical that Python literal values passed to
-        virtually all SQL expression functions are coerced into fixed
-        :func:`.bindparam` constructs.  For example, given a comparison operation
-        such as::
-
-            expr = users_table.c.name == 'Wendy'
-
-        The above expression will produce a :class:`.BinaryExpression`
-        contruct, where the left side is the :class:`.Column` object
-        representing the ``name`` column, and the right side is a :class:`.BindParameter`
-        representing the literal value::
-
-            print(repr(expr.right))
-            BindParameter('%(4327771088 name)s', 'Wendy', type_=String())
-
-        The expression above will render SQL such as::
-
-            user.name = :name_1
-
-        Where the ``:name_1`` parameter name is an anonymous name.  The
-        actual string ``Wendy`` is not in the rendered string, but is carried
-        along where it is later used within statement execution.  If we
-        invoke a statement like the following::
-
-            stmt = select([users_table]).where(users_table.c.name == 'Wendy')
-            result = connection.execute(stmt)
-
-        We would see SQL logging output as::
-
-            SELECT "user".id, "user".name
-            FROM "user"
-            WHERE "user".name = %(name_1)s
-            {'name_1': 'Wendy'}
-
-        Above, we see that ``Wendy`` is passed as a parameter to the database,
-        while the placeholder ``:name_1`` is rendered in the appropriate form
-        for the target database, in this case the Postgresql database.
-
-        Similarly, :func:`.bindparam` is invoked automatically
-        when working with :term:`CRUD` statements as far as the "VALUES"
-        portion is concerned.   The :func:`.insert` construct produces an
-        ``INSERT`` expression which will, at statement execution time, generate
-        bound placeholders based on the arguments passed, as in::
-
-            stmt = users_table.insert()
-            result = connection.execute(stmt, name='Wendy')
-
-        The above will produce SQL output as::
-
-            INSERT INTO "user" (name) VALUES (%(name)s)
-            {'name': 'Wendy'}
-
-        The :class:`.Insert` construct, at compilation/execution time,
-        rendered a single :func:`.bindparam` mirroring the column
-        name ``name`` as a result of the single ``name`` parameter
-        we passed to the :meth:`.Connection.execute` method.
-
-        :param key:
-          the key (e.g. the name) for this bind param.
-          Will be used in the generated
-          SQL statement for dialects that use named parameters.  This
-          value may be modified when part of a compilation operation,
-          if other :class:`BindParameter` objects exist with the same
-          key, or if its length is too long and truncation is
-          required.
-
-        :param value:
-          Initial value for this bind param.  Will be used at statement
-          execution time as the value for this parameter passed to the
-          DBAPI, if no other value is indicated to the statement execution
-          method for this particular parameter name.  Defaults to ``None``.
-
-        :param callable\_:
-          A callable function that takes the place of "value".  The function
-          will be called at statement execution time to determine the
-          ultimate value.   Used for scenarios where the actual bind
-          value cannot be determined at the point at which the clause
-          construct is created, but embedded bind values are still desirable.
-
-        :param type\_:
-          A :class:`.TypeEngine` class or instance representing an optional
-          datatype for this :func:`.bindparam`.  If not passed, a type
-          may be determined automatically for the bind, based on the given
-          value; for example, trivial Python types such as ``str``,
-          ``int``, ``bool``
-          may result in the :class:`.String`, :class:`.Integer` or
-          :class:`.Boolean` types being autoamtically selected.
-
-          The type of a :func:`.bindparam` is significant especially in that
-          the type will apply pre-processing to the value before it is
-          passed to the database.  For example, a :func:`.bindparam` which
-          refers to a datetime value, and is specified as holding the
-          :class:`.DateTime` type, may apply conversion needed to the
-          value (such as stringification on SQLite) before passing the value
-          to the database.
-
-        :param unique:
-          if True, the key name of this :class:`.BindParameter` will be
-          modified if another :class:`.BindParameter` of the same name
-          already has been located within the containing
-          expression.  This flag is used generally by the internals
-          when producing so-called "anonymous" bound expressions, it
-          isn't generally applicable to explicitly-named :func:`.bindparam`
-          constructs.
-
-        :param required:
-          If ``True``, a value is required at execution time.  If not passed,
-          it defaults to ``True`` if neither :paramref:`.bindparam.value`
-          or :paramref:`.bindparam.callable` were passed.  If either of these
-          parameters are present, then :paramref:`.bindparam.required` defaults
-          to ``False``.
-
-          .. versionchanged:: 0.8 If the ``required`` flag is not specified,
-             it will be set automatically to ``True`` or ``False`` depending
-             on whether or not the ``value`` or ``callable`` parameters
-             were specified.
-
-        :param quote:
-          True if this parameter name requires quoting and is not
-          currently known as a SQLAlchemy reserved word; this currently
-          only applies to the Oracle backend, where bound names must
-          sometimes be quoted.
-
-        :param isoutparam:
-          if True, the parameter should be treated like a stored procedure
-          "OUT" parameter.  This applies to backends such as Oracle which
-          support OUT parameters.

-        """Construct a new :class:`.TextClause` clause, representing
-        a textual SQL string directly.
-
-        E.g.::
-
-            fom sqlalchemy import text
-
-            t = text("SELECT * FROM users")
-            result = connection.execute(t)
-
-        The advantages :func:`.text` provides over a plain string are
-        backend-neutral support for bind parameters, per-statement
-        execution options, as well as
-        bind parameter and result-column typing behavior, allowing
-        SQLAlchemy type constructs to play a role when executing
-        a statement that is specified literally.  The construct can also
-        be provided with a ``.c`` collection of column elements, allowing
-        it to be embedded in other SQL expression constructs as a subquery.
-
-        Bind parameters are specified by name, using the format ``:name``.
-        E.g.::
-
-            t = text("SELECT * FROM users WHERE id=:user_id")
-            result = connection.execute(t, user_id=12)
-
-        For SQL statements where a colon is required verbatim, as within
-        an inline string, use a backslash to escape::
-
-            t = text("SELECT * FROM users WHERE name='\\:username'")
-
-        The :class:`.TextClause` construct includes methods which can
-        provide information about the bound parameters as well as the column
-        values which would be returned from the textual statement, assuming
-        it's an executable SELECT type of statement.  The :meth:`.TextClause.bindparams`
-        method is used to provide bound parameter detail, and
-        :meth:`.TextClause.columns` method allows specification of
-        return columns including names and types::
-
-            t = text("SELECT * FROM users WHERE id=:user_id").\\
-                    bindparams(user_id=7).\\
-                    columns(id=Integer, name=String)
-
-            for id, name in connection.execute(t):
-                print(id, name)
-
-        The :func:`.text` construct is used internally in cases when
-        a literal string is specified for part of a larger query, such as
-        when a string is specified to the :meth:`.Select.where` method of
-        :class:`.Select`.  In those cases, the same
-        bind parameter syntax is applied::
-
-            s = select([users.c.id, users.c.name]).where("id=:user_id")
-            result = connection.execute(s, user_id=12)
-
-        Using :func:`.text` explicitly usually implies the construction
-        of a full, standalone statement.   As such, SQLAlchemy refers
-        to it as an :class:`.Executable` object, and it supports
-        the :meth:`Executable.execution_options` method.  For example,
-        a :func:`.text` construct that should be subject to "autocommit"
-        can be set explicitly so using the :paramref:`.Connection.execution_options.autocommit`
-        option::
-
-            t = text("EXEC my_procedural_thing()").\\
-                    execution_options(autocommit=True)
-
-        Note that SQLAlchemy's usual "autocommit" behavior applies to
-        :func:`.text` constructs implicitly - that is, statements which begin
-        with a phrase such as ``INSERT``, ``UPDATE``, ``DELETE``,
-        or a variety of other phrases specific to certain backends, will
-        be eligible for autocommit if no transaction is in progress.
-
-        :param text:
-          the text of the SQL statement to be created.  use ``:<param>``
-          to specify bind parameters; they will be compiled to their
-          engine-specific format.
-
-        :param autocommit:
-          Deprecated.  Use .execution_options(autocommit=<True|False>)
-          to set the autocommit option.
-
-        :param bind:
-          an optional connection or engine to be used for this text query.
-
-        :param bindparams:
-          Deprecated.  A list of :func:`.bindparam` instances used to
-          provide information about parameters embedded in the statement.
-          This argument now invokes the :meth:`.TextClause.bindparams`
-          method on the construct before returning it.  E.g.::
-
-              stmt = text("SELECT * FROM table WHERE id=:id",
-                        bindparams=[bindparam('id', value=5, type_=Integer)])
-
-          Is equivalent to::
-
-              stmt = text("SELECT * FROM table WHERE id=:id").\\
-                        bindparams(bindparam('id', value=5, type_=Integer))
-
-          .. deprecated:: 0.9.0 the :meth:`.TextClause.bindparams` method
-             supersedes the ``bindparams`` argument to :func:`.text`.
-
-        :param typemap:
-          Deprecated.  A dictionary mapping the names of columns
-          represented in the columns clause of a ``SELECT`` statement
-          to type objects,
-          which will be used to perform post-processing on columns within
-          the result set.  This parameter now invokes the :meth:`.TextClause.columns`
-          method, which returns a :class:`.TextAsFrom` construct that gains
-          a ``.c`` collection and can be embedded in other expressions.  E.g.::
-
-              stmt = text("SELECT * FROM table",
-                            typemap={'id': Integer, 'name': String},
-                        )

-
-          .. deprecated:: 0.9.0 the :meth:`.TextClause.columns` method

-                        "AND timestamp=:timestamp")
-
-        the :meth:`.TextClause.bindparams` method can be used to establish

-        using simple keyword arguments::

-
-        Where above, new :class:`.BindParameter` objects
-        will be generated with the names ``name`` and ``timestamp``, and
-        values of ``jack`` and ``datetime.datetime(2012, 10, 8, 15, 12, 5)``,
-        respectively.  The types will be
-        inferred from the values given, in this case :class:`.String` and
-        :class:`.DateTime`.
-
-        When specific typing behavior is needed, the positional ``*binds``
-        argument can be used in which to specify :func:`.bindparam` constructs
-        directly.  These constructs must include at least the ``key`` argument,
-        then an optional value and type::
-
-            from sqlalchemy import bindparam
-            stmt = stmt.bindparams(

-                        )
-
-        Above, we specified the type of :class:`.DateTime` for the ``timestamp``
-        bind, and the type of :class:`.String` for the ``name`` bind.  In
-        the case of ``name`` we also set the default value of ``"jack"``.
-
-        Additional bound parameters can be supplied at statement execution
-        time, e.g.::
-
-            result = connection.execute(stmt,

-        For example, we can call :meth:`.TextClause.bindparams` first with
-        typing information, and a second time with value information, and it
-        will be combined::
-

-        used via the
-        :paramref:`.case.value` parameter, which is passed a column
-        expression to be compared.  In this form, the :paramref:`.case.whens`
-        parameter is passed as a dictionary containing expressions to be compared

-        :paramref:`.case.whens` as well as with :paramref:`.case.else_` are
-        coerced from Python literals into :func:`.bindparam` constructs.
-        SQL expressions, e.g. :class:`.ColumnElement` constructs, are accepted
-        as well.  To coerce a literal string expression into a constant
-        expression rendered inline, use the :func:`.literal_column` construct,

-
-        The above will render the given constants without using bound
-        parameters for the result values (but still for the comparison
-        values), as in::
-
-            CASE
-                WHEN (orderline.qty > :qty_1) THEN 'greaterthan100'

-
-        :param whens: The criteria to be compared against, :paramref:`.case.whens`
-         accepts two different forms, based on whether or not :paramref:`.case.value`
-         is used.
-
-         In the first form, it accepts a list of 2-tuples; each 2-tuple consists
-         of ``(<sql expression>, <value>)``, where the SQL expression is a
-         boolean expression and "value" is a resulting value, e.g.::
-
-            case([
-                (users_table.c.name == 'wendy', 'W'),
-                (users_table.c.name == 'jack', 'J')
-            ])
-
-         In the second form, it accepts a Python dictionary of comparison values
-         mapped to a resulting value; this form requires :paramref:`.case.value`
-         to be present, and values will be compared using the ``==`` operator,
-         e.g.::
-
-            case(
-                {"wendy": "W", "jack": "J"},
-                value=users_table.c.name
-            )
-
-        :param value: An optional SQL expression which will be used as a
-          fixed "comparison point" for candidate values within a dictionary
-          passed to :paramref:`.case.whens`.

-          result of the ``CASE`` construct if all expressions within
-          :paramref:`.case.whens` evaluate to false.  When omitted, most
-          databases will produce a result of NULL if none of the "when"
-          expressions evaulate to true.

-    ``True`` or ``False``, overrides automatic quoting behavior
-    for this identifier in order to either unconditionally quote
-    or to not quote the name.  If left at its default of ``None``,
-    quoting behavior is applied to the identifier on a per-backend basis
-    based on an examination of the token itself.
-
-    A :class:`.quoted_name` object with ``quote=True`` is also
-    prevented from being modified in the case of a so-called
-    "name normalize" option.  Certain database backends, such as
-    Oracle, Firebird, and DB2 "normalize" case-insensitive names
-    as uppercase.  The SQLAlchemy dialects for these backends
-    convert from SQLAlchemy's lower-case-means-insensitive convention
-    to the upper-case-means-insensitive conventions of those backends.
-    The ``quote=True`` flag here will prevent this conversion from occurring
-    to support an identifier that's quoted as all lower case against
-    such a backend.
-
-    The :class:`.quoted_name` object is normally created automatically
-    when specifying the name for key schema constructs such as :class:`.Table`,
-    :class:`.Column`, and others.   The class can also be passed explicitly
-    as the name to any function that receives a name which can be quoted.
-    Such as to use the :meth:`.Engine.has_table` method with an unconditionally
-    quoted name::
-
-        from sqlaclchemy import create_engine
-        from sqlalchemy.sql.elements import quoted_name

-        engine = create_engine("oracle+cx_oracle://some_dsn")
-        engine.has_table(quoted_name("some_table", True))
-
-    The above logic will run the "has table" logic against the Oracle backend,
-    passing the name exactly as ``"some_table"`` without converting to
-    upper case.

-   functions based on name-based attributes, e.g.::
-
-        >>> print func.count(1)
-        count(:param_1)
-
-   The element is a column-oriented SQL element like any other, and is
-   used in that way::
-
-        >>> print select([func.count(table.c.id)])
-        SELECT count(sometable.id) FROM sometable
-
-   Any name can be given to :data:`.func`. If the function name is unknown to
-   SQLAlchemy, it will be rendered exactly as is. For common SQL functions
-   which SQLAlchemy is aware of, the name may be interpreted as a *generic
-   function* which will be compiled appropriately to the target database::
-
-        >>> print func.current_timestamp()
-        CURRENT_TIMESTAMP
-
-   To call functions which are present in dot-separated packages,
-   specify them in the same manner::
-
-        >>> print func.stats.yield_curve(5, 10)
-        stats.yield_curve(:yield_curve_1, :yield_curve_2)
-
-   SQLAlchemy can be made aware of the return type of functions to enable
-   type-specific lexical and result-based behavior. For example, to ensure
-   that a string-based function returns a Unicode value and is similarly
-   treated as a string in expressions, specify
-   :class:`~sqlalchemy.types.Unicode` as the type:
-
-        >>> print func.my_string(u'hi', type_=Unicode) + ' ' + \
-        ... func.my_string(u'there', type_=Unicode)
-        my_string(:my_string_1) || :my_string_2 || my_string(:my_string_3)
-
-   The object returned by a :data:`.func` call is usually an instance of
-   :class:`.Function`.
-   This object meets the "column" interface, including comparison and labeling
-   functions.  The object can also be passed the :meth:`~.Connectable.execute`
-   method of a :class:`.Connection` or :class:`.Engine`, where it will be
-   wrapped inside of a SELECT statement first::
-
-        print connection.execute(func.current_timestamp()).scalar()
-
-   In a few exception cases, the :data:`.func` accessor
-   will redirect a name to a built-in expression such as :func:`.cast`
-   or :func:`.extract`, as these names have well-known meaning
-   but are not exactly the same as "functions" from a SQLAlchemy
-   perspective.
-
-   .. versionadded:: 0.8 :data:`.func` can return non-function expression
-      constructs for common quasi-functional names like :func:`.cast`

-
-    A generic function is a pre-established :class:`.Function`
-    class that is instantiated automatically when called
-    by name from the :data:`.func` attribute.    Note that
-    calling any name from :data:`.func` has the effect that
-    a new :class:`.Function` instance is created automatically,
-    given that name.  The primary use case for defining
-    a :class:`.GenericFunction` class is so that a function
-    of a particular name may be given a fixed return type.
-    It can also include custom argument parsing schemes as well
-    as additional methods.
-
-    Subclasses of :class:`.GenericFunction` are automatically
-    registered under the name of the class.  For
-    example, a user-defined function ``as_utc()`` would
-    be available immediately::
-
-        from sqlalchemy.sql.functions import GenericFunction
-        from sqlalchemy.types import DateTime
-
-        class as_utc(GenericFunction):
-            type = DateTime
-
-        print select([func.as_utc()])
-
-    User-defined generic functions can be organized into
-    packages by specifying the "package" attribute when defining
-    :class:`.GenericFunction`.   Third party libraries
-    containing many functions may want to use this in order
-    to avoid name conflicts with other systems.   For example,
-    if our ``as_utc()`` function were part of a package
-    "time"::
-
-        class as_utc(GenericFunction):
-            type = DateTime
-            package = "time"
-
-    The above function would be available from :data:`.func`
-    using the package name ``time``::
-
-        print select([func.time.as_utc()])
-
-    A final option is to allow the function to be accessed
-    from one name in :data:`.func` but to render as a different name.
-    The ``identifier`` attribute will override the name used to
-    access the function as loaded from :data:`.func`, but will retain
-    the usage of ``name`` as the rendered name::
-
-        class GeoBuffer(GenericFunction):
-            type = Geometry
-            package = "geo"
-            name = "ST_Buffer"
-            identifier = "buffer"
-
-    The above function will render as follows::
-
-        >>> print func.geo.buffer()
-        ST_Buffer()
-
-    .. versionadded:: 0.8 :class:`.GenericFunction` now supports
-       automatic registration of new functions as well as package
-       and custom naming support.
-
-    .. versionchanged:: 0.8 The attribute name ``type`` is used
-       to specify the function's return type at the class level.
-       Previously, the name ``__return_type__`` was used.  This
-       name is still recognized for backwards-compatibility.

-"""The schema module provides the building blocks for database metadata.
-
-Each element within this module describes a database entity which can be
-created and dropped, or is otherwise part of such an entity.  Examples include
-tables, columns, sequences, and indexes.
-
-All entities are subclasses of :class:`~sqlalchemy.schema.SchemaItem`, and as
-defined in this module they are intended to be agnostic of any vendor-specific
-constructs.
-
-A collection of entities are grouped into a unit called
-:class:`~sqlalchemy.schema.MetaData`. MetaData serves as a logical grouping of
-schema elements, and can also be associated with an actual database connection
-such that operations involving the contained elements can contact the database
-as needed.
-
-Two of the elements here also build upon their "syntactic" counterparts, which
-are defined in :class:`~sqlalchemy.sql.expression.`, specifically
-:class:`~sqlalchemy.schema.Table` and :class:`~sqlalchemy.schema.Column`.
-Since these objects are part of the SQL expression language, they are usable
-as components in SQL expressions.

-                   )
-
-    The :class:`.Table` object constructs a unique instance of itself based
-    on its name and optional schema name within the given
-    :class:`.MetaData` object. Calling the :class:`.Table`
-    constructor with the same name and same :class:`.MetaData` argument
-    a second time will return the *same* :class:`.Table` object - in this way
-    the :class:`.Table` constructor acts as a registry function.
-
-    .. seealso::
-
-        :ref:`metadata_describing` - Introduction to database metadata
-
-    Constructor arguments are as follows:
-
-    :param name: The name of this table as represented in the database.
-
-        The table name, along with the value of the ``schema`` parameter,
-        forms a key which uniquely identifies this :class:`.Table` within
-        the owning :class:`.MetaData` collection.
-        Additional calls to :class:`.Table` with the same name, metadata,
-        and schema name will return the same :class:`.Table` object.
-
-        Names which contain no upper case characters
-        will be treated as case insensitive names, and will not be quoted
-        unless they are a reserved word or contain special characters.
-        A name with any number of upper case characters is considered
-        to be case sensitive, and will be sent as quoted.
-
-        To enable unconditional quoting for the table name, specify the flag
-        ``quote=True`` to the constructor, or use the :class:`.quoted_name`
-        construct to specify the name.
-
-    :param metadata: a :class:`.MetaData` object which will contain this
-        table.  The metadata is used as a point of association of this table
-        with other tables which are referenced via foreign key.  It also
-        may be used to associate this table with a particular
-        :class:`.Connectable`.
-
-    :param \*args: Additional positional arguments are used primarily
-        to add the list of :class:`.Column` objects contained within this
-        table. Similar to the style of a CREATE TABLE statement, other
-        :class:`.SchemaItem` constructs may be added here, including
-        :class:`.PrimaryKeyConstraint`, and :class:`.ForeignKeyConstraint`.
-
-    :param autoload: Defaults to False: the Columns for this table should
-        be reflected from the database. Usually there will be no Column
-        objects in the constructor if this property is set.
-
-    :param autoload_replace: If ``True``, when using ``autoload=True``
-        and ``extend_existing=True``,
-        replace ``Column`` objects already present in the ``Table`` that's
-        in the ``MetaData`` registry with
-        what's reflected.  Otherwise, all existing columns will be
-        excluded from the reflection process.    Note that this does
-        not impact ``Column`` objects specified in the same call to ``Table``
-        which includes ``autoload``, those always take precedence.
-        Defaults to ``True``.
-
-        .. versionadded:: 0.7.5
-
-    :param autoload_with: If autoload==True, this is an optional Engine
-        or Connection instance to be used for the table reflection. If
-        ``None``, the underlying MetaData's bound connectable will be used.
-
-    :param extend_existing: When ``True``, indicates that if this
-        :class:`.Table` is already present in the given :class:`.MetaData`,
-        apply further arguments within the constructor to the existing
-        :class:`.Table`.
-
-        If ``extend_existing`` or ``keep_existing`` are not set, an error is
-        raised if additional table modifiers are specified when
-        the given :class:`.Table` is already present in the :class:`.MetaData`.
-
-        .. versionchanged:: 0.7.4
-            ``extend_existing`` will work in conjunction
-            with ``autoload=True`` to run a new reflection operation against
-            the database; new :class:`.Column` objects will be produced
-            from database metadata to replace those existing with the same
-            name, and additional :class:`.Column` objects not present
-            in the :class:`.Table` will be added.
-
-        As is always the case with ``autoload=True``, :class:`.Column`
-        objects can be specified in the same :class:`.Table` constructor,
-        which will take precedence.  I.e.::
-
-            Table("mytable", metadata,
-                        Column('y', Integer),
-                        extend_existing=True,
-                        autoload=True,
-                        autoload_with=engine
-                    )
-
-        The above will overwrite all columns within ``mytable`` which
-        are present in the database, except for ``y`` which will be used as is
-        from the above definition.   If the ``autoload_replace`` flag
-        is set to False, no existing columns will be replaced.
-
-    :param implicit_returning: True by default - indicates that
-        RETURNING can be used by default to fetch newly inserted primary key
-        values, for backends which support this.  Note that
-        create_engine() also provides an implicit_returning flag.
-
-    :param include_columns: A list of strings indicating a subset of
-        columns to be loaded via the ``autoload`` operation; table columns who
-        aren't present in this list will not be represented on the resulting
-        ``Table`` object. Defaults to ``None`` which indicates all columns
-        should be reflected.
-
-    :param info: Optional data dictionary which will be populated into the
-        :attr:`.SchemaItem.info` attribute of this object.
-
-    :param keep_existing: When ``True``, indicates that if this Table
-        is already present in the given :class:`.MetaData`, ignore
-        further arguments within the constructor to the existing
-        :class:`.Table`, and return the :class:`.Table` object as
-        originally created. This is to allow a function that wishes
-        to define a new :class:`.Table` on first call, but on
-        subsequent calls will return the same :class:`.Table`,
-        without any of the declarations (particularly constraints)
-        being applied a second time. Also see extend_existing.
-
-        If extend_existing or keep_existing are not set, an error is
-        raised if additional table modifiers are specified when
-        the given :class:`.Table` is already present in the :class:`.MetaData`.
-
-    :param listeners: A list of tuples of the form ``(<eventname>, <fn>)``
-        which will be passed to :func:`.event.listen` upon construction.
-        This alternate hook to :func:`.event.listen` allows the establishment
-        of a listener function specific to this :class:`.Table` before
-        the "autoload" process begins.  Particularly useful for
-        the :meth:`.DDLEvents.column_reflect` event::
-
-            def listen_for_reflect(table, column_info):
-                "handle the column reflection event"
-                # ...
-
-            t = Table(
-                'sometable',
-                autoload=True,
-                listeners=[
-                    ('column_reflect', listen_for_reflect)
-                ])
-
-    :param mustexist: When ``True``, indicates that this Table must already
-        be present in the given :class:`.MetaData` collection, else
-        an exception is raised.
-
-    :param prefixes:
-        A list of strings to insert after CREATE in the CREATE TABLE
-        statement.  They will be separated by spaces.
-
-    :param quote: Force quoting of this table's name on or off, corresponding
-        to ``True`` or ``False``.  When left at its default of ``None``,
-        the column identifier will be quoted according to whether the name is
-        case sensitive (identifiers with at least one upper case character are
-        treated as case sensitive), or if it's a reserved word.  This flag
-        is only needed to force quoting of a reserved word which is not known
-        by the SQLAlchemy dialect.
-
-    :param quote_schema: same as 'quote' but applies to the schema identifier.
-
-    :param schema: The schema name for this table, which is required if
-        the table resides in a schema other than the default selected schema
-        for the engine's database connection.  Defaults to ``None``.
-
-        The quoting rules for the schema name are the same as those for the
-        ``name`` parameter, in that quoting is applied for reserved words or
-        case-sensitive names; to enable unconditional quoting for the
-        schema name, specify the flag
-        ``quote_schema=True`` to the constructor, or use the :class:`.quoted_name`
-        construct to specify the name.
-
-    :param useexisting: Deprecated.  Use extend_existing.
-
-    :param \**kw: Additional keyword arguments not mentioned above are
-        dialect specific, and passed in the form ``<dialectname>_<argname>``.
-        See the documentation regarding an individual dialect at

-
-        :param name: The name of this column as represented in the database.
-          This argument may be the first positional argument, or specified
-          via keyword.
-
-          Names which contain no upper case characters
-          will be treated as case insensitive names, and will not be quoted
-          unless they are a reserved word.  Names with any number of upper
-          case characters will be quoted and sent exactly.  Note that this
-          behavior applies even for databases which standardize upper
-          case names as case insensitive such as Oracle.
-
-          The name field may be omitted at construction time and applied
-          later, at any time before the Column is associated with a
-          :class:`.Table`.  This is to support convenient
-          usage within the :mod:`~sqlalchemy.ext.declarative` extension.
-
-        :param type\_: The column's type, indicated using an instance which
-          subclasses :class:`~sqlalchemy.types.TypeEngine`.  If no arguments
-          are required for the type, the class of the type can be sent
-          as well, e.g.::
-
-            # use a type with arguments
-            Column('data', String(50))
-
-            # use no arguments
-            Column('level', Integer)
-
-          The ``type`` argument may be the second positional argument
-          or specified by keyword.
-
-          If the ``type`` is ``None`` or is omitted, it will first default to the special
-          type :class:`.NullType`.  If and when this :class:`.Column` is
-          made to refer to another column using :class:`.ForeignKey`
-          and/or :class:`.ForeignKeyConstraint`, the type of the remote-referenced
-          column will be copied to this column as well, at the moment that
-          the foreign key is resolved against that remote :class:`.Column`
-          object.
-
-          .. versionchanged:: 0.9.0
-            Support for propagation of type to a :class:`.Column` from its
-            :class:`.ForeignKey` object has been improved and should be
-            more reliable and timely.
-
-        :param \*args: Additional positional arguments include various
-          :class:`.SchemaItem` derived constructs which will be applied
-          as options to the column.  These include instances of
-          :class:`.Constraint`, :class:`.ForeignKey`, :class:`.ColumnDefault`,
-          and :class:`.Sequence`.  In some cases an equivalent keyword
-          argument is available such as ``server_default``, ``default``
-          and ``unique``.
-
-        :param autoincrement: This flag may be set to ``False`` to
-          indicate an integer primary key column that should not be
-          considered to be the "autoincrement" column, that is
-          the integer primary key column which generates values
-          implicitly upon INSERT and whose value is usually returned
-          via the DBAPI cursor.lastrowid attribute.   It defaults
-          to ``True`` to satisfy the common use case of a table
-          with a single integer primary key column.  If the table
-          has a composite primary key consisting of more than one
-          integer column, set this flag to True only on the
-          column that should be considered "autoincrement".
-
-          The setting *only* has an effect for columns which are:
-
-          * Integer derived (i.e. INT, SMALLINT, BIGINT).
-
-          * Part of the primary key
-
-          * Are not referenced by any foreign keys, unless
-            the value is specified as ``'ignore_fk'``
-
-            .. versionadded:: 0.7.4
-
-          * have no server side or client side defaults (with the exception
-            of Postgresql SERIAL).
-
-          The setting has these two effects on columns that meet the
-          above criteria:
-
-          * DDL issued for the column will include database-specific
-            keywords intended to signify this column as an
-            "autoincrement" column, such as AUTO INCREMENT on MySQL,
-            SERIAL on Postgresql, and IDENTITY on MS-SQL.  It does
-            *not* issue AUTOINCREMENT for SQLite since this is a
-            special SQLite flag that is not required for autoincrementing
-            behavior.  See the SQLite dialect documentation for
-            information on SQLite's AUTOINCREMENT.
-
-          * The column will be considered to be available as
-            cursor.lastrowid or equivalent, for those dialects which
-            "post fetch" newly inserted identifiers after a row has
-            been inserted (SQLite, MySQL, MS-SQL).  It does not have
-            any effect in this regard for databases that use sequences
-            to generate primary key identifiers (i.e. Firebird, Postgresql,
-            Oracle).
-
-          .. versionchanged:: 0.7.4
-              ``autoincrement`` accepts a special value ``'ignore_fk'``
-              to indicate that autoincrementing status regardless of foreign
-              key references.  This applies to certain composite foreign key
-              setups, such as the one demonstrated in the ORM documentation
-              at :ref:`post_update`.
-
-        :param default: A scalar, Python callable, or
-            :class:`.ColumnElement` expression representing the
-            *default value* for this column, which will be invoked upon insert
-            if this column is otherwise not specified in the VALUES clause of
-            the insert. This is a shortcut to using :class:`.ColumnDefault` as
-            a positional argument; see that class for full detail on the
-            structure of the argument.
-
-            Contrast this argument to ``server_default`` which creates a
-            default generator on the database side.
-
-        :param doc: optional String that can be used by the ORM or similar
-            to document attributes.   This attribute does not render SQL
-            comments (a future attribute 'comment' will achieve that).
-
-        :param key: An optional string identifier which will identify this
-            ``Column`` object on the :class:`.Table`. When a key is provided,
-            this is the only identifier referencing the ``Column`` within the
-            application, including ORM attribute mapping; the ``name`` field
-            is used only when rendering SQL.
-
-        :param index: When ``True``, indicates that the column is indexed.
-            This is a shortcut for using a :class:`.Index` construct on the
-            table. To specify indexes with explicit names or indexes that
-            contain multiple columns, use the :class:`.Index` construct
-            instead.
-
-        :param info: Optional data dictionary which will be populated into the
-            :attr:`.SchemaItem.info` attribute of this object.
-
-        :param nullable: If set to the default of ``True``, indicates the
-            column will be rendered as allowing NULL, else it's rendered as
-            NOT NULL. This parameter is only used when issuing CREATE TABLE
-            statements.
-
-        :param onupdate: A scalar, Python callable, or
-            :class:`~sqlalchemy.sql.expression.ClauseElement` representing a
-            default value to be applied to the column within UPDATE
-            statements, which wil be invoked upon update if this column is not
-            present in the SET clause of the update. This is a shortcut to
-            using :class:`.ColumnDefault` as a positional argument with
-            ``for_update=True``.
-
-        :param primary_key: If ``True``, marks this column as a primary key
-            column. Multiple columns can have this flag set to specify
-            composite primary keys. As an alternative, the primary key of a
-            :class:`.Table` can be specified via an explicit
-            :class:`.PrimaryKeyConstraint` object.
-
-        :param server_default: A :class:`.FetchedValue` instance, str, Unicode
-            or :func:`~sqlalchemy.sql.expression.text` construct representing
-            the DDL DEFAULT value for the column.
-
-            String types will be emitted as-is, surrounded by single quotes::
-
-                Column('x', Text, server_default="val")
-
-                x TEXT DEFAULT 'val'
-
-            A :func:`~sqlalchemy.sql.expression.text` expression will be
-            rendered as-is, without quotes::
-
-                Column('y', DateTime, server_default=text('NOW()'))
-
-                y DATETIME DEFAULT NOW()
-
-            Strings and text() will be converted into a :class:`.DefaultClause`
-            object upon initialization.
-
-            Use :class:`.FetchedValue` to indicate that an already-existing
-            column will generate a default value on the database side which
-            will be available to SQLAlchemy for post-fetch after inserts. This
-            construct does not specify any DDL and the implementation is left
-            to the database, such as via a trigger.
-
-        :param server_onupdate:   A :class:`.FetchedValue` instance
-             representing a database-side default generation function. This
-             indicates to SQLAlchemy that a newly generated value will be
-             available after updates. This construct does not specify any DDL
-             and the implementation is left to the database, such as via a
-             trigger.
-
-        :param quote: Force quoting of this column's name on or off,
-             corresponding to ``True`` or ``False``. When left at its default
-             of ``None``, the column identifier will be quoted according to
-             whether the name is case sensitive (identifiers with at least one
-             upper case character are treated as case sensitive), or if it's a
-             reserved word. This flag is only needed to force quoting of a
-             reserved word which is not known by the SQLAlchemy dialect.
-
-        :param unique: When ``True``, indicates that this column contains a
-             unique constraint, or if ``index`` is ``True`` as well, indicates
-             that the :class:`.Index` should be created with the unique flag.
-             To specify multiple columns in the constraint/index or to specify
-             an explicit name, use the :class:`.UniqueConstraint` or
-             :class:`.Index` constructs explicitly.
-
-        :param system: When ``True``, indicates this is a "system" column,
-             that is a column which is automatically made available by the
-             database, and should not be included in the columns list for a
-             ``CREATE TABLE`` statement.
-
-             For more elaborate scenarios where columns should be conditionally
-             rendered differently on different backends, consider custom
-             compilation rules for :class:`.CreateColumn`.
-
-             ..versionadded:: 0.8.3 Added the ``system=True`` parameter to
-               :class:`.Column`.

-
-    The :class:`.PrimaryKeyConstraint` object is present automatically
-    on any :class:`.Table` object; it is assigned a set of
-    :class:`.Column` objects corresponding to those marked with
-    the :paramref:`.Column.primary_key` flag::
-

-            Column('version_id', Integer(), table=<mytable>, primary_key=True, nullable=False)
-        )
-
-    The primary key of a :class:`.Table` can also be specified by using
-    a :class:`.PrimaryKeyConstraint` object explicitly; in this mode of usage,
-    the "name" of the constraint can also be specified, as well as other
-    options which may be recognized by dialects::
-
-        my_table = Table('mytable', metadata,
-                    Column('id', Integer),
-                    Column('version_id', Integer),

-                    PrimaryKeyConstraint('id', 'version_id', name='mytable_pk')
-                )
-
-    The two styles of column-specification should generally not be mixed.
-    An warning is emitted if the columns present in the
-    :class:`.PrimaryKeyConstraint`
-    don't match the columns that were marked as ``primary_key=True``, if both
-    are present; in this case, the columns are taken strictly from the
-    :class:`.PrimaryKeyConstraint` declaration, and those columns otherwise marked
-    as ``primary_key=True`` are ignored.  This behavior is intended to be
-    backwards compatible with previous behavior.
-
-    .. versionchanged:: 0.9.2  Using a mixture of columns within a
-       :class:`.PrimaryKeyConstraint` in addition to columns marked as
-       ``primary_key=True`` now emits a warning if the lists don't match.
-       The ultimate behavior of ignoring those columns marked with the flag
-       only is currently maintained for backwards compatibility; this warning
-       may raise an exception in a future release.
-
-    For the use case where specific options are to be specified on the
-    :class:`.PrimaryKeyConstraint`, but the usual style of using ``primary_key=True``
-    flags is still desirable, an empty :class:`.PrimaryKeyConstraint` may be
-    specified, which will take on the primary key column collection from
-    the :class:`.Table` based on the flags::
-
-        my_table = Table('mytable', metadata,
-                    Column('id', Integer, primary_key=True),

-                )
-
-    .. versionadded:: 0.9.2 an empty :class:`.PrimaryKeyConstraint` may now
-       be specified for the purposes of establishing keyword arguments with the
-       constraint, independently of the specification of "primary key" columns

-
-            * ``%(column_0_label)s`` - the label of the :class:`.Column` at

-                    correlate(False),
-                name=name
-            )
-
-        The selectable produced by :meth:`.Join.alias` features the same
-        columns as that of the two individual selectables presented under
-        a single name - the individual columns are "auto-labeled", meaning
-        the ``.c.`` collection of the resulting :class:`.Alias` represents
-        the names of the individual columns using a ``<tablename>_<columname>``
-        scheme::
-
-            j.c.table_a_id
-            j.c.table_b_a_id
-
-        :meth:`.Join.alias` also features an alternate
-        option for aliasing joins which produces no enclosing SELECT and
-        does not normally apply labels to the column names.  The
-        ``flat=True`` option will call :meth:`.FromClause.alias`
-        against the left and right sides individually.
-        Using this option, no new ``SELECT`` is produced;
-        we instead, from a construct as below::
-
-            j = table_a.join(table_b, table_a.c.id == table_b.c.a_id)
-            j = j.alias(flat=True)
-
-        we get a result like this::
-
-            table_a AS table_a_1 JOIN table_b AS table_b_1 ON
-            table_a_1.id = table_b_1.a_id
-
-        The ``flat=True`` argument is also propagated to the contained
-        selectables, so that a composite join such as::
-
-            j = table_a.join(
-                    table_b.join(table_c,
-                            table_b.c.id == table_c.c.b_id),
-                    table_b.c.a_id == table_a.c.id
-                ).alias(flat=True)
-
-        Will produce an expression like::
-
-            table_a AS table_a_1 JOIN (
-                    table_b AS table_b_1 JOIN table_c AS table_c_1
-                    ON table_b_1.id = table_c_1.b_id
-            ) ON table_a_1.id = table_b_1.a_id
-
-        The standalone :func:`~.expression.alias` function as well as the
-        base :meth:`.FromClause.alias` method also support the ``flat=True``
-        argument as a no-op, so that the argument can be passed to the

-            :func:`.select`.
-
-        :param columns:
-          A list of :class:`.ClauseElement` objects, typically
-          :class:`.ColumnElement` objects or subclasses, which will form the
-          columns clause of the resulting statement. For all members which are
-          instances of :class:`.Selectable`, the individual :class:`.ColumnElement`
-          members of the :class:`.Selectable` will be added individually to the
-          columns clause. For example, specifying a
-          :class:`~sqlalchemy.schema.Table` instance will result in all the
-          contained :class:`~sqlalchemy.schema.Column` objects within to be added
-          to the columns clause.
-
-          This argument is not present on the form of :func:`select()`
-          available on :class:`~sqlalchemy.schema.Table`.
-
-        :param whereclause:
-          A :class:`.ClauseElement` expression which will be used to form the
-          ``WHERE`` clause.
-
-        :param from_obj:
-          A list of :class:`.ClauseElement` objects which will be added to the
-          ``FROM`` clause of the resulting statement. Note that "from" objects are
-          automatically located within the columns and whereclause ClauseElements.
-          Use this parameter to explicitly specify "from" objects which are not
-          automatically locatable. This could include
-          :class:`~sqlalchemy.schema.Table` objects that aren't otherwise present,
-          or :class:`.Join` objects whose presence will supercede that of the
-          :class:`~sqlalchemy.schema.Table` objects already located in the other
-          clauses.
-
-        :param autocommit:
-          Deprecated.  Use .execution_options(autocommit=<True|False>)
-          to set the autocommit option.
-
-        :param bind=None:
-          an :class:`~.Engine` or :class:`~.Connection` instance
-          to which the
-          resulting :class:`.Select` object will be bound.  The :class:`.Select`
-          object will otherwise automatically bind to whatever
-          :class:`~.base.Connectable` instances can be located within its contained
-          :class:`.ClauseElement` members.
-
-        :param correlate=True:
-          indicates that this :class:`.Select` object should have its
-          contained :class:`.FromClause` elements "correlated" to an enclosing
-          :class:`.Select` object.  This means that any :class:`.ClauseElement`
-          instance within the "froms" collection of this :class:`.Select`
-          which is also present in the "froms" collection of an
-          enclosing select will not be rendered in the ``FROM`` clause
-          of this select statement.
-
-        :param distinct=False:
-          when ``True``, applies a ``DISTINCT`` qualifier to the columns
-          clause of the resulting statement.
-
-          The boolean argument may also be a column expression or list
-          of column expressions - this is a special calling form which
-          is understood by the Postgresql dialect to render the
-          ``DISTINCT ON (<columns>)`` syntax.
-
-          ``distinct`` is also available via the :meth:`~.Select.distinct`
-          generative method.
-
-        :param for_update=False:
-          when ``True``, applies ``FOR UPDATE`` to the end of the
-          resulting statement.
-
-          .. deprecated:: 0.9.0 - use :meth:`.GenerativeSelect.with_for_update`
-             to specify the structure of the ``FOR UPDATE`` clause.
-
-          ``for_update`` accepts various string values interpreted by
-          specific backends, including:
-
-          * ``"read"`` - on MySQL, translates to ``LOCK IN SHARE MODE``;
-            on Postgresql, translates to ``FOR SHARE``.
-          * ``"nowait"`` - on Postgresql and Oracle, translates to
-            ``FOR UPDATE NOWAIT``.
-          * ``"read_nowait"`` - on Postgresql, translates to
-            ``FOR SHARE NOWAIT``.
-
-         .. seealso::
-
-            :meth:`.GenerativeSelect.with_for_update` - improved API for
-            specifying the ``FOR UPDATE`` clause.
-
-        :param group_by:
-          a list of :class:`.ClauseElement` objects which will comprise the
-          ``GROUP BY`` clause of the resulting select.
-
-        :param having:
-          a :class:`.ClauseElement` that will comprise the ``HAVING`` clause
-          of the resulting select when ``GROUP BY`` is used.
-
-        :param limit=None:
-          a numerical value which usually compiles to a ``LIMIT``
-          expression in the resulting select.  Databases that don't
-          support ``LIMIT`` will attempt to provide similar
-          functionality.
-
-        :param offset=None:
-          a numeric value which usually compiles to an ``OFFSET``
-          expression in the resulting select.  Databases that don't
-          support ``OFFSET`` will attempt to provide similar
-          functionality.
-
-        :param order_by:
-          a scalar or list of :class:`.ClauseElement` objects which will
-          comprise the ``ORDER BY`` clause of the resulting select.
-
-        :param use_labels=False:
-          when ``True``, the statement will be generated using labels
-          for each column in the columns clause, which qualify each
-          column with its parent table's (or aliases) name so that name
-          conflicts between columns in different tables don't occur.
-          The format of the label is <tablename>_<column>.  The "c"
-          collection of the resulting :class:`.Select` object will use these
-          names as well for targeting column members.
-
-          use_labels is also available via the :meth:`~.GenerativeSelect.apply_labels`
-          generative method.

-            Due to a bug fix, this method has a slight
-            behavioral change as of version 0.7.3.
-            Prior to version 0.7.3, the FROM clause of
-            a :func:`.select` was calculated upfront and as new columns
-            were added; in 0.7.3 and later it's calculated
-            at compile time, fixing an issue regarding late binding
-            of columns to parent tables.  This changes the behavior of
-            :meth:`.Select.with_only_columns` in that FROM clauses no
-            longer represented in the new list are dropped,
-            but this behavior is more consistent in
-            that the FROM clauses are consistently derived from the
-            current columns clause.  The original intent of this method
-            is to allow trimming of the existing columns list to be fewer
-            columns than originally present; the use case of replacing
-            the columns list with an entirely different one hadn't
-            been anticipated until 0.7.3 was released; the usage
-            guidelines below illustrate how this should be done.
-
-        This method is exactly equivalent to as if the original
-        :func:`.select` had been called with the given columns
-        clause.   I.e. a statement::
-
-            s = select([table1.c.a, table1.c.b])
-            s = s.with_only_columns([table1.c.b])
-
-        should be exactly equivalent to::
-
-            s = select([table1.c.b])
-
-        This means that FROM clauses which are only derived
-        from the column list will be discarded if the new column
-        list no longer contains that FROM::
-
-            >>> table1 = table('t1', column('a'), column('b'))
-            >>> table2 = table('t2', column('a'), column('b'))
-            >>> s1 = select([table1.c.a, table2.c.b])
-            >>> print s1
-            SELECT t1.a, t2.b FROM t1, t2
-            >>> s2 = s1.with_only_columns([table2.c.b])
-            >>> print s2
-            SELECT t2.b FROM t1
-
-        The preferred way to maintain a specific FROM clause
-        in the construct, assuming it won't be represented anywhere
-        else (i.e. not in the WHERE clause, etc.) is to set it using
-        :meth:`.Select.select_from`::
-
-            >>> s1 = select([table1.c.a, table2.c.b]).\\
-            ...         select_from(table1.join(table2,
-            ...                 table1.c.a==table2.c.a))
-            >>> s2 = s1.with_only_columns([table2.c.b])
-            >>> print s2
-            SELECT t2.b FROM t1 JOIN t2 ON t1.a=t2.a
-
-        Care should also be taken to use the correct
-        set of column objects passed to :meth:`.Select.with_only_columns`.
-        Since the method is essentially equivalent to calling the
-        :func:`.select` construct in the first place with the given
-        columns, the columns passed to :meth:`.Select.with_only_columns`
-        should usually be a subset of those which were passed
-        to the :func:`.select` construct, not those which are available
-        from the ``.c`` collection of that :func:`.select`.  That
-        is::
-
-            s = select([table1.c.a, table1.c.b]).select_from(table1)
-            s = s.with_only_columns([table1.c.b])
-
-        and **not**::
-
-            # usually incorrect
-            s = s.with_only_columns([s.c.b])
-
-        The latter would produce the SQL::
-
-            SELECT b
-            FROM (SELECT t1.a AS a, t1.b AS b
-            FROM t1), t1
-
-        Since the :func:`.select` construct is essentially being
-        asked to select both from ``table1`` as well as itself.

-          directly supports unicode, such as ``NVARCHAR``.

-          is to be encoded/decoded by SQLAlchemy on a backend

-          SQLAlchemy is not guaranteed to handle the task of unicode
-          conversion.   Note that this flag adds significant performance
-          overhead to row-fetching operations for backends that already
-          return unicode objects natively (which most DBAPIs do).  This

-
-    The :class:`.Unicode` type is a :class:`.String` subclass
-    that assumes input and output as Python ``unicode`` data,
-    and in that regard is equivalent to the usage of the
-    ``convert_unicode`` flag with the :class:`.String` type.
-    However, unlike plain :class:`.String`, it also implies an
-    underlying column type that is explicitly supporting of non-ASCII
-    data, such as ``NVARCHAR`` on Oracle and SQL Server.
-    This can impact the output of ``CREATE TABLE`` statements
-    and ``CAST`` functions at the dialect level, and can
-    also affect the handling of bound parameters in some
-    specific DBAPI scenarios.
-
-    The encoding used by the :class:`.Unicode` type is usually
-    determined by the DBAPI itself; most modern DBAPIs
-    feature support for Python ``unicode`` objects as bound
-    values and result set values, and the encoding should
-    be configured as detailed in the notes for the target
-    DBAPI in the :ref:`dialect_toplevel` section.
-
-    For those DBAPIs which do not support, or are not configured
-    to accommodate Python ``unicode`` objects
-    directly, SQLAlchemy does the encoding and decoding
-    outside of the DBAPI.   The encoding in this scenario
-    is determined by the ``encoding`` flag passed to
-    :func:`.create_engine`.
-
-    When using the :class:`.Unicode` type, it is only appropriate
-    to pass Python ``unicode`` objects, and not plain ``str``.
-    If a plain ``str`` is passed under Python 2, a warning
-    is emitted.  If you notice your application emitting these warnings but
-    you're not sure of the source of them, the Python
-    ``warnings`` filter, documented at
-    http://docs.python.org/library/warnings.html,
-    can be used to turn these warnings into exceptions
-    which will illustrate a stack trace::
-
-      import warnings
-      warnings.simplefilter('error')
-
-    For an application that wishes to pass plain bytestrings
-    and Python ``unicode`` objects to the ``Unicode`` type
-    equally, the bytestrings must first be decoded into
-    unicode.  The recipe at :ref:`coerce_to_unicode` illustrates
-    how this is done.

-
-    This method is preferred to direct subclassing of SQLAlchemy's
-    built-in types as it ensures that all required functionality of

-
-    Typical usage::
-
-      import sqlalchemy.types as types
-
-      class MyType(types.TypeDecorator):
-          '''Prefixes Unicode values with "PREFIX:" on the way in and

-
-          def copy(self):
-              return MyType(self.impl.length)
-
-    The class-level "impl" attribute is required, and can reference any
-    TypeEngine class.  Alternatively, the load_dialect_impl() method
-    can be used to provide different type classes based on the dialect
-    given; in this case, the "impl" variable can reference
-    ``TypeEngine`` as a placeholder.
-
-    Types that receive a Python type that isn't similar to the ultimate type
-    used may want to define the :meth:`TypeDecorator.coerce_compared_value`
-    method. This is used to give the expression system a hint when coercing
-    Python objects into bind parameters within expressions. Consider this
-    expression::
-
-        mytable.c.somecol + datetime.date(2009, 5, 15)
-
-    Above, if "somecol" is an ``Integer`` variant, it makes sense that
-    we're doing date arithmetic, where above is usually interpreted
-    by databases as adding a number of days to the given date.
-    The expression system does the right thing by not attempting to
-    coerce the "date()" value into an integer-oriented bind parameter.
-
-    However, in the case of ``TypeDecorator``, we are usually changing an
-    incoming Python type to something new - ``TypeDecorator`` by default will
-    "coerce" the non-typed side to be the same type as itself. Such as below,
-    we define an "epoch" type that stores a date value as an integer::
-
-        class MyEpochType(types.TypeDecorator):
-            impl = types.Integer
-
-            epoch = datetime.date(1970, 1, 1)
-
-            def process_bind_param(self, value, dialect):
-                return (value - self.epoch).days
-
-            def process_result_value(self, value, dialect):
-                return self.epoch + timedelta(days=value)
-
-    Our expression of ``somecol + date`` with the above type will coerce the
-    "date" on the right side to also be treated as ``MyEpochType``.
-
-    This behavior can be overridden via the
-    :meth:`~TypeDecorator.coerce_compared_value` method, which returns a type
-    that should be used for the value of the expression. Below we set it such
-    that an integer value will be treated as an ``Integer``, and any other
-    value is assumed to be a date and will be treated as a ``MyEpochType``::
-
-        def coerce_compared_value(self, op, value):
-            if isinstance(value, int):

-"""Visitor/traversal interface and library functions.
-
-SQLAlchemy schema and expression constructs rely on a Python-centric
-version of the classic "visitor" pattern as the primary way in which
-they apply functionality.  The most common use of this pattern
-is statement compilation, where individual expression classes match
-up to rendering methods that produce a string result.   Beyond this,
-the visitor system is also used to inspect expressions for various
-information and patterns, as well as for usage in
-some kinds of expression transformation.  Other kinds of transformation
-use a non-visitor traversal system.
-
-For many examples of how the visit system is used, see the
-sqlalchemy.sql.util and the sqlalchemy.sql.compiler modules.
-For an introduction to clause adaption, see

-Nose test runner module.
-
-This script is a front-end to "nosetests" which
-installs SQLAlchemy's testing plugin into the local environment.
-
-The script is intended to be used by third-party dialects and extensions
-that run within SQLAlchemy's testing framework.    The runner can
-be invoked via::
-
-    python -m sqlalchemy.testing.runner
-
-The script is then essentially the same as the "nosetests" script, including
-all of the usual Nose options.   The test environment requires that a
-setup.cfg is locally present including various required options.
-
-Note that when using this runner, Nose's "coverage" plugin will not be
-able to provide coverage for SQLAlchemy itself, since SQLAlchemy is
-imported into sys.modules before coverage is started.   The special
-script sqla_nose.py is provided as a top-level script which loads the
-plugin in a special (somewhat hacky) way so that coverage against
-SQLAlchemy itself is possible.

+
+    Originally released under LGPL.  Graciously donated to PIL in
+    March 2009, for distribution under the standard PIL license
+
+    The pyCMS.py module provides a "clean" interface between Python/PIL and
+    pyCMSdll, taking care of some of the more complex handling of the direct
+    pyCMSdll functions, as well as error-checking and making sure that all
+    relevant data is kept together.
+
+    While it is possible to call pyCMSdll functions directly, it's not highly
+    recommended.
+
+    Version History:
+
+        1.0.0 pil       Oct 2013 Port to LCMS 2.
+
+        0.1.0 pil mod   March 10, 2009
+
+                        Renamed display profile to proof profile. The proof
+                        profile is the profile of the device that is being
+                        simulated, not the profile of the device which is
+                        actually used to display/print the final simulation
+                        (that'd be the output profile) - also see LCMSAPI.txt
+                        input colorspace -> using 'renderingIntent' -> proof
+                        colorspace -> using 'proofRenderingIntent' -> output
+                        colorspace
+
+                        Added LCMS FLAGS support.
+                        Added FLAGS["SOFTPROOFING"] as default flag for
+                        buildProofTransform (otherwise the proof profile/intent
+                        would be ignored).
+
+        0.1.0 pil       March 2009 - added to PIL, as PIL.ImageCms
+
+        0.0.2 alpha     Jan 6, 2002
+
+                        Added try/except statements arount type() checks of
+                        potential CObjects... Python won't let you use type()
+                        on them, and raises a TypeError (stupid, if you ask
+                        me!)
+
+                        Added buildProofTransformFromOpenProfiles() function.
+                        Additional fixes in DLL, see DLL code for details.
+
+        0.0.1 alpha     first public release, Dec. 26, 2002

+# base class for image file handlers
+#
+# history:
+# 1995-09-09 fl   Created
+# 1996-03-11 fl   Fixed load mechanism.
+# 1996-04-15 fl   Added pcx/xbm decoders.
+# 1996-04-30 fl   Added encoders.
+# 1996-12-14 fl   Added load helpers
+# 1997-01-11 fl   Use encode_to_file where possible
+# 1997-08-27 fl   Flush output in _save
+# 1998-03-05 fl   Use memory mapping for some modes
+# 1999-02-04 fl   Use memory mapping also for "I;16" and "I;16B"
+# 1999-05-31 fl   Added image parser
+# 2000-10-12 fl   Set readonly flag on memory-mapped images
+# 2002-03-20 fl   Use better messages for common decoder errors
+# 2003-04-21 fl   Fall back on mmap/map_buffer if map is not available
+# 2003-10-30 fl   Added StubImageFile class
+# 2004-02-25 fl   Made incremental parser more robust

+JPEG quality settings equivalent to the Photoshop settings.
+
+More presets can be added to the presets dict if needed.
+
+Can be use when saving JPEG file.
+
+To apply the preset, specify::
+
+  quality="preset_name"
+
+To apply only the quantization table::
+
+  qtables="preset_name"
+
+To apply only the subsampling setting::
+
+  subsampling="preset_name"
+
+Example::
+
+  im.save("image_name.jpg", quality="web_high")
+
+
+Subsampling
+-----------
+
+Subsampling is the practice of encoding images by implementing less resolution
+for chroma information than for luma information.
+(ref.: http://en.wikipedia.org/wiki/Chroma_subsampling)
+
+Possible subsampling values are 0, 1 and 2 that correspond to 4:4:4, 4:2:2 and
+4:1:1 (or 4:2:0?).
+
+You can get the subsampling of a JPEG with the
+`JpegImagePlugin.get_subsampling(im)` function.
+
+
+Quantization tables
+-------------------
+
+They are values use by the DCT (Discrete cosine transform) to remove
+*unnecessary* information from the image (the lossy part of the compression).
+(ref.: http://en.wikipedia.org/wiki/Quantization_matrix#Quantization_matrices,
+http://en.wikipedia.org/wiki/JPEG#Quantization)
+
+You can get the quantization tables of a JPEG with::
+
+  im.quantization
+
+This will return a dict with a number of arrays. You can pass this dict directly
+as the qtables argument when saving a JPEG.
+
+The tables format between im.quantization and quantization in presets differ in
+3 ways:
+
+1. The base container of the preset is a list with sublists instead of dict.
+   dict[0] -> list[0], dict[1] -> list[1], ...
+2. Each table in a preset is a list instead of an array.
+3. The zigzag order is remove in the preset (needed by libjpeg >= 6a).
+
+You can convert the dict format to the preset format with the
+`JpegImagePlugin.convert_dict_qtables(dict_qtables)` function.

+OleFileIO_PL
+============
+
+[OleFileIO_PL](http://www.decalage.info/python/olefileio) is a Python module to parse and read [Microsoft OLE2 files (also called Structured Storage, Compound File Binary Format or Compound Document File Format)](http://en.wikipedia.org/wiki/Compound_File_Binary_Format), such as Microsoft Office documents, Image Composer and FlashPix files, Outlook messages, StickyNotes, several Microscopy file formats ...
+
+This is an improved version of the OleFileIO module from [PIL](http://www.pythonware.com/products/pil/index.htm), the excellent Python Imaging Library, created and maintained by Fredrik Lundh. The API is still compatible with PIL, but since 2005 I have improved the internal implementation significantly, with new features, bugfixes and a more robust design.
+
+As far as I know, this module is now the most complete and robust Python implementation to read MS OLE2 files, portable on several operating systems. (please tell me if you know other similar Python modules)
+
+OleFileIO_PL can be used as an independent module or with PIL. The goal is to have it integrated into [Pillow](http://python-pillow.github.io/), the friendly fork of PIL.
+
+OleFileIO\_PL is mostly meant for developers. If you are looking for tools to analyze OLE files or to extract data, then please also check [python-oletools](http://www.decalage.info/python/oletools), which are built upon OleFileIO_PL.

+
+
+How to use this module
+----------------------
+
+OleFileIO_PL can be used as an independent module or with PIL. The main functions and methods are explained below.
+
+For more information, see also the file **OleFileIO_PL.html**, sample code at the end of the module itself, and docstrings within the code.
+
+### About the structure of OLE files ###
+
+An OLE file can be seen as a mini file system or a Zip archive: It contains **streams** of data that look like files embedded within the OLE file. Each stream has a name. For example, the main stream of a MS Word document containing its text is named "WordDocument".
+
+An OLE file can also contain **storages**. A storage is a folder that contains streams or other storages. For example, a MS Word document with VBA macros has a storage called "Macros".
+
+Special streams can contain **properties**. A property is a specific value that can be used to store information such as the metadata of a document (title, author, creation date, etc). Property stream names usually start with the character '\x05'.
+
+For example, a typical MS Word document may look like this:
+
+	\x05DocumentSummaryInformation (stream)
+	\x05SummaryInformation (stream)
+	WordDocument (stream)
+	Macros (storage)
+		PROJECT (stream)
+		PROJECTwm (stream)
+		VBA (storage)
+			Module1 (stream)
+			ThisDocument (stream)
+			_VBA_PROJECT (stream)
+			dir (stream)
+	ObjectPool (storage)
+
+
+
+### Import OleFileIO_PL ###
+
+	:::python
+		import OleFileIO_PL
+
+As of version 0.30, the code has been changed to be compatible with Python 3.x. As a consequence, compatibility with Python 2.5 or older is not provided anymore. However, a copy of v0.26 is available as OleFileIO_PL2.py. If your application needs to be compatible with Python 2.5 or older, you may use the following code to load the old version when needed:
+
+	:::python
+		try:
+			import OleFileIO_PL
+		except:
+			import OleFileIO_PL2 as OleFileIO_PL
+
+If you think OleFileIO_PL should stay compatible with Python 2.5 or older, please [contact me](http://decalage.info/contact).
+
+
+### Test if a file is an OLE container ###
+
+Use isOleFile to check if the first bytes of the file contain the Magic for OLE files, before opening it. isOleFile returns True if it is an OLE file, False otherwise (new in v0.16).
+
+	:::python
+		assert OleFileIO_PL.isOleFile('myfile.doc')
+
+
+### Open an OLE file from disk ###
+
+Create an OleFileIO object with the file path as parameter:
+
+	:::python
+		ole = OleFileIO_PL.OleFileIO('myfile.doc')
+
+### Open an OLE file from a file-like object ###
+
+This is useful if the file is not on disk, e.g. already stored in a string or as a file-like object.
+
+	:::python
+		ole = OleFileIO_PL.OleFileIO(f)
+
+For example the code below reads a file into a string, then uses BytesIO to turn it into a file-like object.
+
+	:::python
+		data = open('myfile.doc', 'rb').read()
+		f = io.BytesIO(data) # or StringIO.StringIO for Python 2.x
+		ole = OleFileIO_PL.OleFileIO(f)
+
+### How to handle malformed OLE files ###
+
+By default, the parser is configured to be as robust and permissive as possible, allowing to parse most malformed OLE files. Only fatal errors will raise an exception. It is possible to tell the parser to be more strict in order to raise exceptions for files that do not fully conform to the OLE specifications, using the raise_defect option (new in v0.14):
+
+	:::python
+		ole = OleFileIO_PL.OleFileIO('myfile.doc', raise_defects=DEFECT_INCORRECT)
+
+When the parsing is done, the list of non-fatal issues detected is available as a list in the parsing_issues attribute of the OleFileIO object (new in 0.25):
+
+	:::python
+        print('Non-fatal issues raised during parsing:')
+        if ole.parsing_issues:
+            for exctype, msg in ole.parsing_issues:
+                print('- %s: %s' % (exctype.__name__, msg))
+        else:
+            print('None')
+
+
+### Syntax for stream and storage path ###
+
+Two different syntaxes are allowed for methods that need or return the path of streams and storages:
+
+1) Either a **list of strings** including all the storages from the root up to the stream/storage name. For example a stream called "WordDocument" at the root will have ['WordDocument'] as full path. A stream called "ThisDocument" located in the storage "Macros/VBA" will be ['Macros', 'VBA', 'ThisDocument']. This is the original syntax from PIL. While hard to read and not very convenient, this syntax works in all cases.
+
+2) Or a **single string with slashes** to separate storage and stream names (similar to the Unix path syntax). The previous examples would be 'WordDocument' and 'Macros/VBA/ThisDocument'. This syntax is easier, but may fail if a stream or storage name contains a slash. (new in v0.15)
+
+Both are case-insensitive.
+
+Switching between the two is easy:
+
+	:::python
+		slash_path = '/'.join(list_path)
+		list_path  = slash_path.split('/')
+
+
+### Get the list of streams ###
+
+listdir() returns a list of all the streams contained in the OLE file, including those stored in storages. Each stream is listed itself as a list, as described above.
+
+	:::python
+		print(ole.listdir())
+
+Sample result:
+
+	:::python
+		[['\x01CompObj'], ['\x05DocumentSummaryInformation'], ['\x05SummaryInformation']
+		, ['1Table'], ['Macros', 'PROJECT'], ['Macros', 'PROJECTwm'], ['Macros', 'VBA',
+		'Module1'], ['Macros', 'VBA', 'ThisDocument'], ['Macros', 'VBA', '_VBA_PROJECT']
+		, ['Macros', 'VBA', 'dir'], ['ObjectPool'], ['WordDocument']]
+
+As an option it is possible to choose if storages should also be listed, with or without streams (new in v0.26):
+
+	:::python
+		ole.listdir (streams=False, storages=True)
+
+
+### Test if known streams/storages exist: ###
+
+exists(path) checks if a given stream or storage exists in the OLE file (new in v0.16).
+
+	:::python
+		if ole.exists('worddocument'):
+		    print("This is a Word document.")
+		    if ole.exists('macros/vba'):
+		         print("This document seems to contain VBA macros.")
+
+
+### Read data from a stream ###
+
+openstream(path) opens a stream as a file-like object.
+
+The following example extracts the "Pictures" stream from a PPT file:
+
+	:::python
+	    pics = ole.openstream('Pictures')
+	    data = pics.read()
+
+
+### Get information about a stream/storage ###
+
+Several methods can provide the size, type and timestamps of a given stream/storage:
+
+get_size(path) returns the size of a stream in bytes (new in v0.16):
+
+	:::python
+		s = ole.get_size('WordDocument')
+
+get_type(path) returns the type of a stream/storage, as one of the following constants: STGTY\_STREAM for a stream, STGTY\_STORAGE for a storage, STGTY\_ROOT for the root entry, and False for a non existing path (new in v0.15).
+
+	:::python
+		t = ole.get_type('WordDocument')
+
+get\_ctime(path) and get\_mtime(path) return the creation and modification timestamps of a stream/storage, as a Python datetime object with UTC timezone. Please note that these timestamps are only present if the application that created the OLE file explicitly stored them, which is rarely the case. When not present, these methods return None (new in v0.26).
+
+	:::python
+		c = ole.get_ctime('WordDocument')
+		m = ole.get_mtime('WordDocument')
+
+The root storage is a special case: You can get its creation and modification timestamps using the OleFileIO.root attribute (new in v0.26):
+
+	:::python
+		c = ole.root.getctime()
+		m = ole.root.getmtime()
+
+### Extract metadata ###
+
+get_metadata() will check if standard property streams exist, parse all the properties they contain, and return an OleMetadata object with the found properties as attributes (new in v0.24).
+
+	:::python
+		meta = ole.get_metadata()
+		print('Author:', meta.author)
+		print('Title:', meta.title)
+		print('Creation date:', meta.create_time)
+		# print all metadata:
+		meta.dump()
+
+Available attributes include:
+
+    codepage, title, subject, author, keywords, comments, template,
+    last_saved_by, revision_number, total_edit_time, last_printed, create_time,
+    last_saved_time, num_pages, num_words, num_chars, thumbnail,
+    creating_application, security, codepage_doc, category, presentation_target,
+    bytes, lines, paragraphs, slides, notes, hidden_slides, mm_clips,
+    scale_crop, heading_pairs, titles_of_parts, manager, company, links_dirty,
+    chars_with_spaces, unused, shared_doc, link_base, hlinks, hlinks_changed,
+    version, dig_sig, content_type, content_status, language, doc_version
+
+See the source code of the OleMetadata class for more information.
+
+
+### Parse a property stream ###
+
+get\_properties(path) can be used to parse any property stream that is not handled by get\_metadata. It returns a dictionary indexed by integers. Each integer is the index of the property, pointing to its value. For example in the standard property stream '\x05SummaryInformation', the document title is property #2, and the subject is #3.
+
+	:::python
+		p = ole.getproperties('specialprops')
+
+By default as in the original PIL version, timestamp properties are converted into a number of seconds since Jan 1,1601. With the option convert\_time, you can obtain more convenient Python datetime objects (UTC timezone). If some time properties should not be converted (such as total editing time in '\x05SummaryInformation'), the list of indexes can be passed as no_conversion (new in v0.25):
+
+	:::python
+		p = ole.getproperties('specialprops', convert_time=True, no_conversion=[10])
+
+
+### Close the OLE file ###
+
+Unless your application is a simple script that terminates after processing an OLE file, do not forget to close each OleFileIO object after parsing to close the file on disk. (new in v0.22)
+
+	:::python
+		ole.close()
+
+### Use OleFileIO_PL as a script ###
+
+OleFileIO_PL can also be used as a script from the command-line to display the structure of an OLE file and its metadata, for example:
+
+	OleFileIO_PL.py myfile.doc
+
+You can use the option -c to check that all streams can be read fully, and -d to generate very verbose debugging information.
+
+## Real-life examples ##
+
+A real-life example: [using OleFileIO_PL for malware analysis and forensics](http://blog.gregback.net/2011/03/using-remnux-for-forensic-puzzle-6/).

+#-----------------------------------------------------------------------------
+# TODO (for version 1.0):
+# + isOleFile should accept file-like objects like open
+# + fix how all the methods handle unicode str and/or bytes as arguments
+# + add path attrib to _OleDirEntry, set it once and for all in init or
+#   append_kids (then listdir/_list can be simplified)
+# - TESTS with Linux, MacOSX, Python 1.5.2, various files, PIL, ...
+# - add underscore to each private method, to avoid their display in
+#   pydoc/epydoc documentation - Remove it for classes to be documented
+# - replace all raised exceptions with _raise_defect (at least in OleFileIO)
+# - merge code from _OleStream and OleFileIO.getsect to read sectors
+#   (maybe add a class for FAT and MiniFAT ?)
+# - add method to check all streams (follow sectors chains without storing all
+#   stream in memory, and report anomalies)
+# - use _OleDirectoryEntry.kids_dict to improve _find and _list ?
+# - fix Unicode names handling (find some way to stay compatible with Py1.5.2)
+#   => if possible avoid converting names to Latin-1
+# - review DIFAT code: fix handling of DIFSECT blocks in FAT (not stop)
+# - rewrite OleFileIO.getproperties
+# - improve docstrings to show more sample uses
+# - see also original notes and FIXME below
+# - remove all obsolete FIXMEs
+# - OleMetadata: fix version attrib according to
+#   http://msdn.microsoft.com/en-us/library/dd945671%28v=office.12%29.aspx
+
+# IDEAS:
+# - in OleFileIO._open and _OleStream, use size=None instead of 0x7FFFFFFF for
+#   streams with unknown size
+# - use arrays of int instead of long integers for FAT/MiniFAT, to improve
+#   performance and reduce memory usage ? (possible issue with values >2^31)
+# - provide tests with unittest (may need write support to create samples)
+# - move all debug code (and maybe dump methods) to a separate module, with
+#   a class which inherits OleFileIO ?
+# - fix docstrings to follow epydoc format
+# - add support for 4K sectors ?
+# - add support for big endian byte order ?
+# - create a simple OLE explorer with wxPython
+
+# FUTURE EVOLUTIONS to add write support:
+# 1) add ability to write a stream back on disk from BytesIO (same size, no
+#    change in FAT/MiniFAT).
+# 2) rename a stream/storage if it doesn't change the RB tree
+# 3) use rbtree module to update the red-black tree + any rename
+# 4) remove a stream/storage: free sectors in FAT/MiniFAT
+# 5) allocate new sectors in FAT/MiniFAT
+# 6) create new storage/stream

+# TIFF file handling
+#
+# TIFF is a flexible, if somewhat aged, image file format originally
+# defined by Aldus.  Although TIFF supports a wide variety of pixel
+# layouts and compression methods, the name doesn't really stand for
+# "thousands of incompatible file formats," it just feels that way.
+#
+# To read TIFF data from a stream, the stream must be seekable.  For
+# progressive decoding, make sure to use TIFF files where the tag
+# directory is placed first in the file.
+#
+# History:
+# 1995-09-01 fl   Created
+# 1996-05-04 fl   Handle JPEGTABLES tag
+# 1996-05-18 fl   Fixed COLORMAP support
+# 1997-01-05 fl   Fixed PREDICTOR support
+# 1997-08-27 fl   Added support for rational tags (from Perry Stoll)
+# 1998-01-10 fl   Fixed seek/tell (from Jan Blom)
+# 1998-07-15 fl   Use private names for internal variables
+# 1999-06-13 fl   Rewritten for PIL 1.0 (1.0)
+# 2000-10-11 fl   Additional fixes for Python 2.0 (1.1)
+# 2001-04-17 fl   Fixed rewind support (seek to frame 0) (1.2)
+# 2001-05-12 fl   Added write support for more tags (from Greg Couch) (1.3)
+# 2001-12-18 fl   Added workaround for broken Matrox library
+# 2002-01-18 fl   Don't mess up if photometric tag is missing (D. Alan Stewart)
+# 2003-05-19 fl   Check FILLORDER tag
+# 2003-09-26 fl   Added RGBa support
+# 2004-02-24 fl   Added DPI support; fixed rational write support
+# 2005-02-07 fl   Added workaround for broken Corel Draw 10 files
+# 2006-01-09 fl   Added support for float/double tags (from Russell Nelson)

+            *** Changes from release 1.1.6 to 1.1.7 ***
+        
+            This section may not be fully complete.  For changes since this file
+            was last updated, see the repository revision history:
+        
+              http://bitbucket.org/effbot/pil-2009-raclette/changesets/
+        
+            (1.1.7 final)
+        
+            + Set GIF loop info property to the number of iterations if a NETSCAPE
+              loop extension is present, instead of always setting it to 1 (from
+              Valentino Volonghi).
+        
+            (1.1.7c1 released)
+        
+            + Improved PNG compression (from Alexey Borzenkov).
+        
+            + Read interlaced PNG files (from Conrado Porto Lopes Gouvêa)
+        
+            + Added various TGA improvements from Alexey Borzenkov, including
+              support for specifying image orientation.
+        
+            + Bumped block threshold to 16 megabytes, made size estimation a bit
+              more accurate.  This speeds up allocation of large images.
+        
+            + Fixed rounding error in ImagingDrawWideLine.
+        
+              "gormish" writes: ImagingDrawWideLine() in Draw.c has a bug in every
+              version I've seen, which leads to different width lines depending on
+              the order of the points in the line. This is especially bad at some
+              angles where a 'width=2' line can completely disappear.
+        
+            + Added support for RGBA mode to the SGI module (based on code by
+              Karsten Hiddemann).
+        
+            + Handle repeated IPTC tags (adapted from a patch by Eric Bruning).
+        
+              Eric writes: According to the specification, some IPTC tags can be
+              repeated, e.g., tag 2:25 (keywords). PIL 1.1.6 only retained the last
+              instance of that tag. Below is a patch to store all tags. If there are
+              multiple tag instances, they are stored in a (python) list. Single tag
+              instances remain as strings.
+        
+            + Fixed potential crash in ImageFilter for small target images
+              (reported by Zac Burns and Daniel Fetchinson).
+        
+            + Use BMP instead of JPEG as temporary show format on Mac OS X.
+        
+            + Fixed putpixel/new for I;16 with colors > 255.
+        
+            + Added integer power support to ImagingMath.
+        
+            + Added limited support for I;16L mode (explicit little endian).
+        
+            + Moved WMF support into Image.core; enable WMF rendering by default
+              if renderer is available.
+        
+            + Mark the ARG plugin as obsolete.
+        
+            + Added version query mechanism to ImageCms and ImageFont, for
+              debugging.
+        
+            + Added (experimental) ImageCms function for fetching the ICC profile
+              for the current display (currently Windows only).
+        
+              Added HWND/HDC support to ImageCms.get_display_profile().
+        
+            + Added WMF renderer (Windows only).
+        
+            + Added ImagePointHandler and ImageTransformHandler mixins; made
+              ImageCmsTransform work with im.point.
+        
+            + Fixed potential endless loop in the XVThumbnail reader (from Nikolai
+              Ugelvik).
+        
+            + Added Kevin Cazabon's pyCMS package.
+        
+              The C code has been moved to _imagingcms.c, the Python interface
+              module is installed as PIL.ImageCMS.
+        
+              Added support for in-memory ICC profiles.
+        
+              Unified buildTransform and buildTransformFromOpenProfiles.
+        
+              The profile can now be either a filename, a profile object, or a
+              file-like object containing an in-memory profile.
+        
+              Additional fixes from Florian Böch:
+        
+                Very nice - it just needs LCMS flags support so we can use black
+                point compensation and softproofing :) See attached patches.  They
+                also fix a naming issue which could cause confusion - display
+                profile (ImageCms wording) actually means proof profile (lcms
+                wording), so I changed variable names and docstrings where
+                applicable. Patches are tested under Python 2.6.
+        
+            + Improved support for layer names in PSD files (from Sylvain Baubeau)
+        
+              Sylvain writes: I needed to be able to retrieve the names of the
+              layers in a PSD files. But PsdImagePlugin.py didn't do the job so I
+              wrote this very small patch.
+        
+            + Improved RGBA support for ImageTk for 8.4 and newer (from Con
+              Radchenko).
+        
+              This replaces the slow run-length based encoding model with true
+              compositing at the Tk level.
+        
+            + Added support for 16- and 32-bit images to McIdas loader.
+        
+              Based on file samples and stand-alone reader code provided by Craig
+              Swank.
+        
+            + Added ImagePalette support to putpalette.
+        
+            + Fixed problem with incremental parsing of PNG files.
+        
+            + Make selftest.py report non-zero status on failure (from Mark
+              Sienkiewicz)
+        
+            + Add big endian save support and multipage infrastructure to the TIFF
+              writer (from Sebastian Haase).
+        
+            + Handle files with GPS IFD but no basic EXIF IFD (reported by Kurt
+              Schwehr).
+        
+            + Added zTXT support (from Andrew Kuchling via Lowell Alleman).
+        
+            + Fixed potential infinite loop bug in ImageFont (from Guilherme Polo).
+        
+            + Added sample ICC profiles (from Kevin Cazabon)
+        
+            + Fixed array interface for I, F, and RGBA/RGBX images.
+        
+            + Added Chroma subsampling support for JPEG (from Justin Huff).
+        
+              Justin writes: Attached is a patch (against PIL 1.1.6) to provide
+              control over the chroma subsampling done by the JPEG encoder.  This
+              is often useful for reducing compression artifacts around edges of
+              clipart and text.
+        
+            + Added USM/Gaussian Blur code from Kevin Cazabon.
+        
+            + Fixed bug w. uninitialized image data when cropping outside the
+              source image.
+        
+            + Use ImageShow to implement the Image.show method.
+        
+              Most notably, this picks the 'display' utility when available.  It
+              also allows application code to register new display utilities via
+              the ImageShow registry.
+        
+            + Release the GIL in the PNG compressor (from Michael van Tellingen).
+        
+            + Revised JPEG CMYK handling.
+        
+              Always assume Adobe behaviour, both when reading and writing (based on
+              a patch by Kevin Cazabon, and test data by Tim V. and Charlie Clark, and
+              additional debugging by Michael van Tellingen).
+        
+            + Support for preserving ICC profiles (by Florian Böch via Tim Hatch).
+        
+              Florian writes:
+        
+              It's a beta, so still needs some testing, but should allow you to:
+              - retain embedded ICC profiles when saving from/to JPEG, PNG, TIFF.
+                 Existing code doesn't need to be changed.
+              - access embedded profiles in JPEG, PNG, PSD, TIFF.
+        
+              It also includes patches for TIFF to retain IPTC, Photoshop and XMP
+              metadata when saving as TIFF again, read/write TIFF resolution
+              information correctly, and to correct inverted CMYK JPEG files.
+        
+            + Fixed potential memory leak in median cut quantizer (from Evgeny Salmin).
+        
+            + Fixed OverflowError when reading upside-down BMP images.
+        
+            + Added resolution save option for PDF files.
+        
+              Andreas Kostyrka writes: I've included a patched PdfImagePlugin.py
+              based on 1.1.6 as included in Ubuntu, that supports a "resolution"
+              save option. Not great, but it makes the PDF saving more useful by
+              allowing PDFs that are not exactly 72dpi.
+        
+            + Look for Tcl/Tk include files in version-specific include directory
+              (from Encolpe Degoute).
+        
+            + Fixed grayscale rounding error in ImageColor.getcolor (from Tim
+              Hatch).
+        
+            + Fixed calculation of mean value in ImageEnhance.Contrast (reported
+              by "roop" and Scott David Daniels).
+        
+            + Fixed truetype positioning when first character has a negative left
+              bearing (from Ned Batchelder):
+        
+              Ned writes: In PIL 1.1.6, ImageDraw.text will position the string
+              incorrectly if the first character has a negative left bearing.  To
+              see the problem, show a string like "///" in an italic font.  The
+              first slash will be clipped at the left, and the string will be
+              mis-positioned.
+        
+            + Fixed resolution unit bug in tiff reader/writer (based on code by
+              Florian Höch, Gary Bloom, and others).
+        
+            + Added simple transparency support for RGB images (reported by
+              Sebastian Spaeth).
+        
+            + Added support for Unicode filenames in ImageFont.truetype (from Donn
+              Ingle).
+        
+            + Fixed potential crash in ImageFont.getname method (from Donn Ingle).
+        
+            + Fixed encoding issue in PIL/WalImageFile (from Santiago M. Mola).
+        
+            *** Changes from release 1.1.5 to 1.1.6 ***
+        
+            (1.1.6 released)
+        
+            + Fixed some 64-bit compatibility warnings for Python 2.5.
+        
+            + Added threading support for the Sane driver (from Abel Deuring).
+        
+            (1.1.6b2 released)
+        
+            + Added experimental "floodfill" function to the ImageDraw module
+              (based on code by Eric Raymond).
+        
+            + The default arguments for "frombuffer" doesn't match "fromstring"
+              and the documentation; this is a bug, and will most likely be fixed
+              in a future version.  In this release, PIL prints a warning message
+              instead.  To silence the warning, change any calls of the form
+              "frombuffer(mode, size, data)" to
+        
+                  frombuffer(mode, size, data, "raw", mode, 0, 1)
+        
+            + Added "fromarray" function, which takes an object implementing the
+              NumPy array interface and creates a PIL Image from it. (from Travis
+              Oliphant).
+        
+            + Added NumPy array interface support (__array_interface__) to the
+              Image class (based on code by Travis Oliphant).
+        
+              This allows you to easily convert between PIL image memories and
+              NumPy arrays:
+        
+                import numpy, Image
+        
+                im = Image.open('lena.jpg')
+        
+                a = numpy.asarray(im) # a is readonly
+        
+                im = Image.fromarray(a)
+        
+            + Fixed CMYK polarity for JPEG images, by treating all images as
+              "Adobe CMYK" images. (thanks to Cesare Leonardi and Kevin Cazabon
+              for samples, debugging, and patches).
+        
+            (1.1.6b1 released)
+        
+            + Added 'expand' option to the Image 'rotate' method.  If true, the
+              output image is made large enough to hold the entire rotated image.
+        
+            + Changed the ImageDraw 'line' method to always draw the last pixel in
+              a polyline, independent of line angle.
+        
+            + Fixed bearing calculation and clipping in the ImageFont truetype
+              renderer; this could lead to clipped text, or crashes in the low-
+              level _imagingft module.  (based on input from Adam Twardoch and
+              others).
+        
+            + Added ImageQt wrapper module, for converting PIL Image objects to
+              QImage objects in an efficient way.
+        
+            + Fixed 'getmodebands' to return the number of bands also for "PA"
+              and "LA" modes.  Added 'getmodebandnames' helper that return the
+              band names.
+        
+            (1.1.6a2 released)
+        
+            + Added float/double support to the TIFF loader (from Russell
+              Nelson).
+        
+            + Fixed broken use of realloc() in path.c (from Jan Matejek)
+        
+            + Added save support for Spider images (from William Baxter).
+        
+            + Fixed broken 'paste' and 'resize' operations in pildriver
+              (from Bill Janssen).
+        
+            + Added support for duplex scanning to the Sane interface (Abel
+              Deuring).
+        
+            (1.1.6a1 released)
+        
+            + Fixed a memory leak in "convert(mode)", when converting from
+              L to P.
+        
+            + Added pixel access object.  The "load" method now returns a
+              access object that can be used to directly get and set pixel
+              values, using ordinary [x, y] notation:
+        
+                pixel = im.load()
+                v = pixel[x, y]
+                pixel[x, y] = v
+        
+              If you're accessing more than a few pixels, this is a lot
+              faster than using getpixel/putpixel.
+        
+            + Fixed building on Cygwin (from Miki Tebeka).
+        
+            + Fixed "point(callable)" on unloaded images (reported by HÃ¥kan
+              Karlsson).
+        
+            + Fixed size bug in ImageWin.ImageWindow constructor (from Victor
+              Reijs)
+        
+            + Fixed ImageMath float() and int() operations for Python 2.4
+              (reported by Don Rozenberg).
+        
+            + Fixed "RuntimeError: encoder error -8 in tostring" problem for
+              wide "RGB", "I", and "F" images.
+        
+            + Fixed line width calculation.
+        
+            (1.1.6a0 released)
+        
+            + Fixed byte order issue in Image.paste(ink) (from Ka-Ping Yee).
+        
+            + Fixed off-by-0.5 errors in the ANTIALIAS code (based on input
+              from Douglas Bagnall).
+        
+            + Added buffer interface support to the Path constructor.  If
+              a buffer is provided, it is assumed to contain a flat array
+              of float coordinates (e.g. array.array('f', seq)).
+        
+            + Added new ImageMath module.
+        
+            + Fixed ImageOps.equalize when used with a small number of distinct
+              values (reported by David Kirtley).
+        
+            + Fixed potential integer division in PSDraw.image (from Eric Etheridge).
+        
+            *** Changes from release 1.1 to 1.1.5 ***
+        
+            (1.1.5c2 and 1.1.5 final released)
+        
+            + Added experimental PERSPECTIVE transform method (from Jeff Breiden-
+              bach).
+        
+            (1.1.5c1 released)
+        
+            + Make sure "thumbnail" never generates zero-wide or zero-high images
+              (reported by Gene Skonicki)
+        
+            + Fixed a "getcolors" bug that could result in a zero count for some
+              colors (reported by Richard Oudkerk).
+        
+            + Changed default "convert" palette to avoid "rounding errors" when
+              round-tripping white source pixels (reported by Henryk Gerlach and
+              Jeff Epler).
+        
+            (1.1.5b3 released)
+        
+            + Don't crash in "quantize" method if the number of colors requested
+              is larger than 256.  This release raises a ValueError exception;
+              future versions may return a mode "RGB" image instead (reported
+              by Richard Oudkerk).
+        
+            + Added WBMP read/write support (based on code by Duncan Booth).
+        
+            (1.1.5b2 released)
+        
+            + Added DPI read/write support to the PNG codec.  The decoder sets
+              the info["dpi"] attribute for PNG files with appropriate resolution
+              settings.  The encoder uses the "dpi" option (based on code by Niki
+              Spahiev).
+        
+            + Added limited support for "point" mappings from mode "I" to mode "L".
+              Only 16-bit values are supported (other values are clipped), the lookup
+              table must contain exactly 65536 entries, and the mode argument must be
+              set to "L".
+        
+            + Added support for Mac OS X icns files (based on code by Bob Ippolito).
+        
+            + Added "ModeFilter" support to the ImageFilter module.
+        
+            + Added support for Spider images (from William Baxter).  See the
+              comments in PIL/SpiderImagePlugin.py for more information on this
+              format.
+        
+            (1.1.5b1 released)
+        
+            + Added new Sane release (from Ralph Heinkel).  See the Sane/README
+              and Sane/CHANGES files for more information.
+        
+            + Added experimental PngInfo chunk container to the PngImageFile
+              module.  This can be used to add arbitrary chunks to a PNG file.
+              Create a PngInfo instance, use "add" or "add_text" to add chunks,
+              and pass the instance as the "pnginfo" option when saving the
+              file.
+        
+            + Added "getpalette" method.  This returns the palette as a list,
+              or None if the image has no palette.  To modify the palette, use
+              "getpalette" to fetch the current palette, modify the list, and
+              put it back using "putpalette".
+        
+            + Added optional flattening to the ImagePath "tolist" method.
+              tolist() or tolist(0) returns a list of 2-tuples, as before.
+              tolist(1) returns a flattened list instead.
+        
+            (1.1.5a5 released)
+        
+            + Fixed BILINEAR/BICUBIC/ANTIALIAS filtering for mode "LA".
+        
+            + Added "getcolors()" method.  This is similar to the existing histo-
+              gram method, but looks at color values instead of individual layers,
+              and returns an unsorted list of (count, color) tuples.
+        
+              By default, the method returns None if finds more than 256 colors.
+              If you need to look for more colors, you can pass in a limit (this
+              is used to allocate internal tables, so you probably don't want to
+              pass in too large values).
+        
+            + Build improvements: Fixed building under AIX, improved detection of
+              FreeType2 and Mac OS X framework libraries, and more.  Many thanks
+              to everyone who helped test the new "setup.py" script!
+        
+            (1.1.5a4 released)
+        
+            + The "save" method now looks for a file format driver before
+              creating the file.
+        
+            + Don't use antialiased truetype fonts when drawing in mode "P", "I",
+              and "F" images.
+        
+            + Rewrote the "setup.py" file.  The new version scans for available
+              support libraries, and configures both the libImaging core library
+              and the bindings in one step.
+        
+              To use specific versions of the libraries, edit the ROOT variables
+              in the setup.py file.
+        
+            + Removed threaded "show" viewer; use the old "show" implementation
+              instead (Windows).
+        
+            + Added deprecation warnings to Image.offset, ImageDraw.setink, and
+              ImageDraw.setfill.
+        
+            + Added width option to ImageDraw.line().  The current implementation
+              works best for straight lines; it does not support line joins, so
+              polylines won't look good.
+        
+            + ImageDraw.Draw is now a factory function instead of a class.  If
+              you need to create custom draw classes, inherit from the ImageDraw
+              class.    All other code should use the factory function.
+        
+            + Fixed loading of certain PCX files (problem reported by Greg
+              Hamilton, who also provided samples).
+        
+            + Changed _imagingft.c to require FreeType 2.1 or newer.  The
+              module can still be built with earlier versions; see comments
+              in _imagingft.c for details.
+        
+            (1.1.5a3 released)
+        
+            + Added 'getim' method, which returns a PyCObject wrapping an
+              Imaging pointer.  The description string is set to IMAGING_MAGIC.
+              See Imaging.h for pointer and string declarations.
+        
+            + Fixed reading of TIFF JPEG images (problem reported by Ulrik
+              Svensson).
+        
+            + Made ImageColor work under Python 1.5.2
+        
+            + Fixed division by zero "equalize" on very small images (from
+              Douglas Bagnall).
+        
+            (1.1.5a2 released)
+        
+            + The "paste" method now supports the alternative "paste(im, mask)"
+              syntax (in this case, the box defaults to im's bounding box).
+        
+            + The "ImageFile.Parser" class now works also for PNG files with
+              more than one IDAT block.
+        
+            + Added DPI read/write to the TIFF codec, and fixed writing of
+              rational values.  The decoder sets the info["dpi"] attribute
+              for TIFF files with appropriate resolution settings.  The
+              encoder uses the "dpi" option.
+        
+            + Disable interlacing for small (or narrow) GIF images, to
+              work around what appears to be a hard-to-find bug in PIL's
+              GIF encoder.
+        
+            + Fixed writing of mode "P" PDF images.  Made mode "1" PDF
+              images smaller.
+        
+            + Made the XBM reader a bit more robust; the file may now start
+              with a few whitespace characters.
+        
+            + Added support for enhanced metafiles to the WMF driver.  The
+              separate PILWMF kit lets you render both placeable WMF files
+              and EMF files as raster images.  See
+        
+                  http://effbot.org/downloads#pilwmf
+        
+            (1.1.5a1 released)
+        
+            + Replaced broken WMF driver with a WMF stub plugin (see below).
+        
+            + Fixed writing of mode "1", "L", and "CMYK" PDF images (based on
+              input from Nicholas Riley and others).
+        
+            + Fixed adaptive palette conversion for zero-width or zero-height
+              images (from Chris Cogdon)
+        
+            + Fixed reading of PNG images from QuickTime 6 (from Paul Pharr)
+        
+            + Added support for StubImageFile plugins, including stub plugins
+              for BUFR, FITS, GRIB, and HDF5 files.  A stub plugin can identify
+              a given file format, but relies on application code to open and
+              save files in that format.
+        
+            + Added optional "encoding" argument to the ImageFont.truetype
+              factory.  This argument can be used to specify non-Unicode character
+              maps for fonts that support that.  For example, to draw text using
+              the Microsoft Symbol font, use:
+        
+                  font = ImageFont.truetype("symbol.ttf", 16, encoding="symb")
+                  draw.text((0, 0), unichr(0xF000 + 0xAA))
+        
+              (note that the symbol font uses characters in the 0xF000-0xF0FF
+               range)
+        
+              Common encodings are "unic" (Unicode), "symb" (Microsoft Symbol),
+              "ADOB" (Adobe Standard), "ADBE" (Adobe Expert), and "armn" (Apple
+              Roman).  See the FreeType documentation for more information.
+        
+            + Made "putalpha" a bit more robust; you can now attach an alpha
+              layer to a plain "L" or "RGB" image, and you can also specify
+              constant alphas instead of alpha layers (using integers or colour
+              names).
+        
+            + Added experimental "LA" mode support.
+        
+              An "LA" image is an "L" image with an attached transparency layer.
+              Note that support for "LA" is not complete; some operations may
+              fail or produce unexpected results.
+        
+            + Added "RankFilter", "MinFilter", "MedianFilter", and "MaxFilter"
+              classes to the ImageFilter module.
+        
+            + Improved support for applications using multiple threads; PIL
+              now releases the global interpreter lock for many CPU-intensive
+              operations (based on work by Kevin Cazabon).
+        
+            + Ignore Unicode characters in the PCF loader (from Andres Polit)
+        
+            + Fixed typo in OleFileIO.loadfat, which could affect loading of
+              FlashPix and Image Composer images (Daniel Haertle)
+        
+            + Fixed building on platforms that have Freetype but don't have
+              Tcl/Tk (Jack Jansen, Luciano Nocera, Piet van Oostrum and others)
+        
+            + Added EXIF GPSInfo read support for JPEG files.  To extract
+              GPSInfo information, open the file, extract the exif dictionary,
+              and check for the key 0x8825 (GPSInfo).  If present, it contains
+              a dictionary mapping GPS keys to GPS values.  For a list of keys,
+              see the EXIF specification.
+        
+              The "ExifTags" module contains a GPSTAGS dictionary mapping GPS
+              tags to tag names.
+        
+            + Added DPI read support to the PCX and DCX codecs (info["dpi"]).
+        
+            + The "show" methods now uses a built-in image viewer on Windows.
+              This viewer creates an instance of the ImageWindow class (see
+              below) and keeps it running in a separate thread.  NOTE: This
+              was disabled in 1.1.5a4.
+        
+            + Added experimental "Window" and "ImageWindow" classes to the
+              ImageWin module.  These classes allow you to create a WCK-style
+              toplevel window, and use it to display raster data.
+        
+            + Fixed some Python 1.5.2 issues (to build under 1.5.2, use the
+              Makefile.pre.in/Setup.in approach)
+        
+            + Added support for the TIFF FillOrder tag.  PIL can read mode "1",
+              "L", "P" and "RGB" images with non-standard FillOrder (based on
+              input from Jeff Breidenbach).
+        
+            (1.1.4 final released)
+        
+            + Fixed ImageTk build problem on Unix.
+        
+            (1.1.4b2 released)
+        
+            + Improved building on Mac OS X (from Jack Jansen).
+        
+            + Improved building on Windows with MinGW (from Klamer Shutte).
+        
+            + If no font is specified, ImageDraw now uses the embedded default
+              font.  Use the "load" or "truetype" methods to load a real font.
+        
+            + Added embedded default font to the ImageFont module (currently
+              an 8-pixel Courier font, taken from the X window distribution).
+        
+            (1.1.4b1 released)
+        
+            + Added experimental EXIF support for JPEG files.  To extract EXIF
+              information from a JPEG file, open the file as usual, and call the
+              "_getexif" method.  If successful, this method returns a dictionary
+              mapping EXIF TIFF tags to values.  If the file does not contain EXIF
+              data, the "_getexif" method returns None.
+        
+              The "ExifTags" module contains a dictionary mapping tags to tag
+              names.
+        
+              This interface will most likely change in future versions.
+        
+            + Fixed a bug when using the "transparency" option with the GIF
+              writer.
+        
+            + Added limited support for "bitfield compression" in BMP files
+              and DIB buffers, for 15-bit, 16-bit, and 32-bit images.  This
+              also fixes a problem with ImageGrab module when copying screen-
+              dumps from the clipboard on 15/16/32-bit displays.
+        
+            + Added experimental WAL (Quake 2 textures) loader.  To use this
+              loader, import WalImageFile and call the "open" method in that
+              module.
+        
+            (1.1.4a4 released)
+        
+            + Added updated SANE driver (Andrew Kuchling, Abel Deuring)
+        
+            + Use Python's "mmap" module on non-Windows platforms to read some
+              uncompressed formats using memory mapping.  Also added a "frombuffer"
+              function that allows you to access the contents of an existing string
+              or buffer object as if it were an image object.
+        
+            + Fixed a memory leak that could appear when processing mode "P"
+              images (from Pier Paolo Glave)
+        
+            + Ignore Unicode characters in the BDF loader (from Graham Dumpleton)
+        
+            (1.1.4a3 released; windows only)
+        
+            + Added experimental RGBA-on-RGB drawing support.  To use RGBA
+              colours on an RGB image, pass "RGBA" as the second string to
+              the ImageDraw.Draw constructor.
+        
+            + Added support for non-ASCII strings (Latin-1) and Unicode
+              to the truetype font renderer.
+        
+            + The ImageWin "Dib" object can now be constructed directly from
+              an image object.
+        
+            + The ImageWin module now allows you use window handles as well
+              as device contexts.  To use a window handle, wrap the handle in
+              an ImageWin.HWND object, and pass in this object instead of the
+              device context.
+        
+            (1.1.4a2 released)
+        
+            + Improved support for 16-bit unsigned integer images (mode "I;16").
+              This includes TIFF reader support, and support for "getextrema"
+              and "point" (from Klamer Shutte).
+        
+            + Made the BdfFontFile reader a bit more robust (from Kevin Cazabon
+              and Dmitry Vasiliev)
+        
+            + Changed TIFF writer to always write Compression tag, even when
+              using the default compression (from Greg Couch).
+        
+            + Added "show" support for Mac OS X (from Dan Wolfe).
+        
+            + Added clipboard support to the "ImageGrab" module (Windows only).
+              The "grabclipboard" function returns an Image object, a list of
+              filenames (not in 1.1.4), or None if neither was found.
+        
+            (1.1.4a1 released)
+        
+            + Improved support for drawing RGB data in palette images.  You can
+              now use RGB tuples or colour names (see below) when drawing in a
+              mode "P" image.  The drawing layer automatically assigns color
+              indexes, as long as you don't use more than 256 unique colours.
+        
+            + Moved self test from MiniTest/test.py to ./selftest.py.
+        
+            + Added support for CSS3-style color strings to most places that
+              accept colour codes/tuples.  This includes the "ImageDraw" module,
+              the Image "new" function, and the Image "paste" method.
+        
+              Colour strings can use one of the following formats: "#f00",
+              "#ff0000", "rgb(255,0,0)", "rgb(100%,0%,0%)", "hsl(0, 100%, 50%)",
+              or "red" (most X11-style colour names are supported).  See the
+              documentation for the "ImageColor" module for more information.
+        
+            + Fixed DCX decoder (based on input from Larry Bates)
+        
+            + Added "IptcImagePlugin.getiptcinfo" helper to extract IPTC/NAA
+              newsphoto properties from JPEG, TIFF, or IPTC files.
+        
+            + Support for TrueType/OpenType fonts has been added to
+              the standard distribution.  You need the freetype 2.0
+              library.
+        
+            + Made the PCX reader a bit more robust when reading 2-bit
+              and 4-bit PCX images with odd image sizes.
+        
+            + Added "Kernel" class to the ImageFilter module.  This class
+              allows you to filter images with user-defined 3x3 and 5x5
+              convolution kernels.
+        
+            + Added "putdata" support for mode "I", "F" and "RGB".
+        
+            + The GIF writer now supports the transparency option (from
+              Denis Benoit).
+        
+            + A HTML version of the module documentation is now shipped
+              with the source code distribution.  You'll find the files in
+              the Doc subdirectory.
+        
+            + Added support for Palm pixmaps (from Bill Janssen).  This
+              change was listed for 1.1.3, but the "PalmImagePlugin" driver
+              didn't make it into the distribution.
+        
+            + Improved decoder error messages.
+        
+            (1.1.3 final released)
+        
+            + Made setup.py look for old versions of zlib.  For some back-
+              ground, see: http://www.gzip.org/zlib/advisory-2002-03-11.txt
+        
+            (1.1.3c2 released)
+        
+            + Added setup.py file (tested on Unix and Windows).  You still
+              need to build libImaging/imaging.lib in the traditional way,
+              but the setup.py script takes care of the rest.
+        
+              The old Setup.in/Makefile.pre.in build method is still
+              supported.
+        
+            + Fixed segmentation violation in ANTIALIAS filter (an internal
+              buffer wasn't properly allocated).
+        
+            (1.1.3c1 released)
+        
+            + Added ANTIALIAS downsampling filter for high-quality "resize"
+              and "thumbnail" operations.  Also added filter option to the
+              "thumbnail" operation; the default value is NEAREST, but this
+              will most likely change in future versions.
+        
+            + Fixed plugin loader to be more robust if the __file__
+              variable isn't set.
+        
+            + Added seek/tell support (for layers) to the PhotoShop
+              loader.  Layer 0 is the main image.
+        
+            + Added new (but experimental) "ImageOps" module, which provides
+              shortcuts for commonly used operations on entire images.
+        
+            + Don't mess up when loading PNG images if the decoder leaves
+              data in the output buffer.  This could cause internal errors
+              on some PNG images, with some versions of ZLIB. (Bug report
+              and patch provided by Bernhard Herzog.)
+        
+            + Don't mess up on Unicode filenames.
+        
+            + Don't mess up when drawing on big endian platforms.
+        
+            + Made the TIFF loader a bit more robust; it can now read some
+              more slightly broken TIFF files (based on input from Ted Wright,
+              Bob Klimek, and D. Alan Stewart)
+        
+            + Added OS/2 EMX build files (from Andrew MacIntyre)
+        
+            + Change "ImageFont" to reject image files if they don't have the
+              right mode.  Older versions could leak memory for "P" images.
+              (Bug reported by Markus Gritsch).
+        
+            + Renamed some internal functions to avoid potential build
+              problem on Mac OS X.
+        
+            + Added DL_EXPORT where relevant (for Cygwin, based on input
+              from Robert Yodlowski)
+        
+            + (re)moved bogus __init__ call in BdfFontFile (bug spotted
+              by Fred Clare)
+        
+            + Added "ImageGrab" support (Windows only)
+        
+            + Added support for XBM hotspots (based on code contributed by
+              Bernhard Herzog).
+        
+            + Added write support for more TIFF tags, namely the Artist,
+              Copyright, DateTime, ResolutionUnit, Software, XResolution and
+              YResolution tags (from Greg Couch)
+        
+            + Added TransposedFont wrapper to ImageFont module
+        
+            + Added "optimize" flag to GIF encoder.  If optimize is present
+              and non-zero, PIL will work harder to create a small file.
+        
+            + Raise "EOFError" (not IndexError) when reading beyond the
+              end of a TIFF sequence.
+        
+            + Support rewind ("seek(0)") for GIF and TIFF sequences.
+        
+            + Load grayscale GIF images as mode "L"
+        
+            + Added DPI read/write support to the JPEG codec.  The decoder
+              sets the info["dpi"] attribute for JPEG files with JFIF dpi
+              settings.  The encoder uses the "dpi" option:
+        
+                  im = Image.open("file.jpg")
+                  dpi = im.info["dpi"] # raises KeyError if DPI not known
+                  im.save("out.jpg", dpi=dpi)
+        
+              Note that PIL doesn't always preserve the "info" attribute
+              for normal image operations.
+        
+            (1.1.2c1 and 1.1.2 final released)
+        
+            + Adapted to Python 2.1.  Among other things, all uses of the
+              "regex" module has been repleased with "re".
+        
+            + Fixed attribute error when reading large PNG files (this bug
+              was introduced in maintenance code released after the 1.1.1
+              release)
+        
+            + Ignore non-string objects in sys.path
+        
+            + Fixed Image.transform(EXTENT) for negative xoffsets
+        
+            + Fixed loading of image plugins if PIL is installed as a package.
+              (The plugin loader now always looks in the directory where the
+              Image.py module itself is found, even if that directory isn't on
+              the standard search path)
+        
+            + The Png plugin has been added to the list of preloaded standard
+              formats
+        
+            + Fixed bitmap/text drawing in fill mode.
+        
+            + Fixed "getextrema" to work also for multiband images.
+        
+            + Added transparency support for L and P images to the PNG codec.
+        
+            + Improved support for read-only images.  The "load" method now
+              sets the "readonly" attribute for memory-mapped images.  Operations
+              that modifies an image in place (such as "paste" and drawing operations)
+              creates an in-memory copy of the image, if necessary.  (before this
+              change, any attempt to modify a memory-mapped image resulted in a
+              core dump...)
+        
+            + Added special cases for lists everywhere PIL expects a sequence.
+              This should speed up things like "putdata" and drawing operations.
+        
+            + The Image.offset method is deprecated.  Use the ImageChops.offset
+              function instead.
+        
+            + Changed ImageChops operators to copy palette and info dictionary
+              from the first image argument.
+        
+            (1.1.1 released)
+        
+            + Additional fixes for Python 1.6/2.0, including TIFF "save" bug.
+        
+            + Changed "init" to properly load plugins when PIL is used as a
+              package.
+        
+            + Fixed broken "show" method (on Unix)
+        
+            *** Changes from release 1.0 to 1.1 ***
+        
+            + Adapted to Python 1.6 ("append" and other method changes)
+        
+            + Fixed Image.paste when pasting with solid colour and matte
+              layers ("L" or "RGBA" masks) (bug reported by Robert Kern)
+        
+            + To make it easier to distribute prebuilt versions of PIL,
+              the tkinit binding stuff has been moved to a separate
+              extension module, named "_imagingtk".
+        
+            *** Changes from release 0.3b2 to 1.0 final ***
+        
+            + If there's no 16-bit integer (like on a Cray T3E), set
+              INT16 to the smallest integer available.  Most of the
+              library works just fine anyway (from Bill Crutchfield)
+        
+            + Tweaks to make drawing work on big-endian platforms.
+        
+            (1.0c2 released)
+        
+            + If PIL is built with the WITH_TKINTER flag, ImageTk can
+              automatically hook into a standard Tkinter build.  You
+              no longer need to build your own Tkinter to use the
+              ImageTk module.
+        
+              The old way still works, though.  For more information,
+              see Tk/install.txt.
+        
+            + Some tweaks to ImageTk to support multiple Tk interpreters
+              (from Greg Couch).
+        
+            + ImageFont "load_path" now scans directory mentioned in .pth
+              files (from Richard Jones).
+        
+            (1.0c1 released)
+        
+            + The TIFF plugin has been rewritten.  The new plugin fully
+              supports all major PIL image modes (including F and I).
+        
+            + The ImageFile module now includes a Parser class, which can
+              be used to incrementally decode an image file (while down-
+              loading it from the net, for example).  See the handbook for
+              details.
+        
+            + "show" now converts non-standard modes to "L" or "RGB" (as
+              appropriate), rather than writing weird things to disk for
+              "xv" to choke upon. (bug reported by Les Schaffer).
+        
+            (1.0b2 released)
+        
+            + Major speedups for rotate, transform(EXTENT), and transform(AFFINE)
+              when using nearest neighbour resampling.
+        
+            + Modified ImageDraw to be compatible with the Arrow graphics
+              interface.  See the handbook for details.
+        
+            + PIL now automatically loads file codecs when used as a package
+              (from The Dragon De Monsyne).  Also included an __init__.py file
+              in the standard distribution.
+        
+            + The GIF encoder has been modified to produce much smaller files.
+        
+              PIL now uses a run-length encoding method to encode GIF files.
+              On a random selection of GIF images grabbed from the web, this
+              version makes the images about twice as large as the original
+              LZW files, where the earlier version made them over 5 times
+              larger.  YMMV, of course.
+        
+            + Added PCX write support (works with "1", "P", "L", and "RGB")
+        
+            + Added "bitmap" and "textsize" methods to ImageDraw.
+        
+            + Improved font rendering code.  Fixed a bug or two, and moved
+              most of the time critical stuff to C.
+        
+            + Removed "bdf2pil.py".  Use "pilfont.py" instead!
+        
+            + Improved 16-bit support (still experimental, though).
+        
+              The following methods now support "I;16" and "I;16B" images:
+              "getpixel", "copy", "convert" (to and from mode "I"), "resize",
+              "rotate", and "transform" with nearest neighbour filters, and
+              "save" using the IM format.  The "new" and "open" functions
+              also work as expected.  On Windows, 16-bit files are memory
+              mapped.
+        
+              NOTE: ALL other operations are still UNDEFINED on 16-bit images.
+        
+            + The "paste" method now supports constant sources.
+        
+              Just pass a colour value (a number or a tuple, depending on
+              the target image mode) instead of the source image.
+        
+              This was in fact implemented in an inefficient way in
+              earlier versions (the "paste" method generated a temporary
+              source image if you passed it a colour instead of an image).
+              In this version, this is handled on the C level instead.
+        
+            + Added experimental "RGBa" mode support.
+        
+              An "RGBa" image is an RGBA image where the colour components
+              have have been premultipled with the alpha value.  PIL allows
+              you to convert an RGBA image to an RGBa image, and to paste
+              RGBa images on top of RGB images.  Since this saves a bunch
+              of multiplications and shifts, it is typically about twice
+              as fast an ordinary RGBA paste.
+        
+            + Eliminated extra conversion step when pasting "RGBA" or "RGBa"
+              images on top of "RGB" images.
+        
+            + Fixed Image.BICUBIC resampling for "RGB" images.
+        
+            + Fixed PCX image file handler to properly read 8-bit PCX
+              files (bug introduced in 1.0b1, reported by Bernhard
+              Herzog)
+        
+            + Fixed PSDraw "image" method to restore the coordinate
+              system.
+        
+            + Fixed "blend" problem when applied to images that was
+              not already loaded (reported by Edward C. Jones)
+        
+            + Fixed -f option to "pilconvert.py" (from Anthony Baxter)
+        
+            (1.0b1 released)
+        
+            + Added Toby J. Sargeant's quantization package.  To enable
+              quantization, use the "palette" option to "convert":
+        
+                imOut = im.convert("P", palette=Image.ADAPTIVE)
+        
+              This can be used with "L", "P", and "RGB" images.  In this
+              version, dithering cannot be used with adaptive palettes.
+        
+              Note: ADAPTIVE currently maps to median cut quantization
+              with 256 colours.  The quantization package also contains
+              a maximum coverage quantizer, which will be supported by
+              future versions of PIL.
+        
+            + Added Eric S. Raymond's "pildriver" image calculator to the
+              distribution.  See the docstring for more information.
+        
+            + The "offset" method no longer dumps core if given positive
+              offsets (from Charles Waldman).
+        
+            + Fixed a resource leak that could cause ImageWin to run out of
+              GDI resources (from Roger Burnham).
+        
+            + Added "arc", "chord", and "pieslice" methods to ImageDraw (inspired
+              by code contributed by Richard Jones).
+        
+            + Added experimental 16-bit support, via modes "I;16" (little endian
+              data) and "I;16B" (big endian).  Only a few methods properly support
+              such images (see above).
+        
+            + Added XV thumbnail file handler (from Gene Cash).
+        
+            + Fixed BMP image file handler to handle palette images with small
+              palettes (from Rob Hooft).
+        
+            + Fixed Sun raster file handler for palette images (from Charles
+              Waldman).
+        
+            + Improved various internal error messages.
+        
+            + Fixed Path constructor to handle arbitrary sequence objects.  This
+              also affects the ImageDraw class (from Richard Jones).
+        
+            + Fixed a bug in JpegDecode that caused PIL to report "decoder error
+              -2" for some progressive JPEG files (reported by Magnus Källström,
+              who also provided samples).
+        
+            + Fixed a bug in JpegImagePlugin that caused PIL to hang when loading
+              JPEG files using 16-bit quantization tables.
+        
+            + The Image "transform" method now supports Image.QUAD transforms.
+              The data argument is an 8-tuple giving the upper left, lower
+              left, lower right, and upper right corner of the source quadri-
+              lateral.  Also added Image.MESH transform which takes a list
+              of quadrilaterals.
+        
+            + The Image "resize", "rotate", and "transform" methods now support
+              Image.BILINEAR (2x2) and Image.BICUBIC (4x4) resampling filters.
+              Filters can be used with all transform methods.
+        
+            + The ImageDraw "rectangle" method now includes both the right
+              and the bottom edges when drawing filled rectangles.
+        
+            + The TGA decoder now works properly for runlength encoded images
+              which have more than one byte per pixel.
+        
+            + "getbands" on an YCbCr image now returns ("Y", "Cb", "Cr")
+        
+            + Some file drivers didn't handle the optional "modify" argument
+              to the load method.  This resulted in exceptions when you used
+              "paste" (and other methods that modify an image in place) on a
+              newly opened file.
+        
+            *** Changes from release 0.2 (b5) to 0.3 (b2) ***
+        
+            (0.3b2 released)
+        
+            The test suite includes 825 individual tests.
+        
+            + An Image "getbands" method has been added.  It returns a tuple
+              containing the individual band names for this image.  To figure
+              out how many bands an image has, use "len(im.getbands())".
+        
+            + An Image "putpixel" method has been added.
+        
+            + The Image "point" method can now be used to convert "L" images
+              to any other format, via a lookup table.  That table should
+              contain 256 values for each band in the output image.
+        
+            + Some file drivers (including FLI/FLC, GIF, and IM) accidently
+              overwrote the offset method with an internal attribute.  All
+              drivers have been updated to use private attributes where
+              possible.
+        
+            + The Image "histogram" method now works for "I" and "F" images.
+              For these modes, PIL divides the range between the min and
+              max values used in the image into 256 bins.  You can also
+              pass in your own min and max values via the "extrema" option:
+        
+                h = im.histogram(extrema=(0, 255))
+        
+            + An Image "getextrema" method has been added.  It returns the
+              min and max values used in the image. In this release, this
+              works for single band images only.
+        
+            + Changed the PNG driver to load and save mode "I" images as
+              16-bit images.  When saving, values outside the range 0..65535
+              are clipped.
+        
+            + Fixed ImageFont.py to work with the new "pilfont" compiler.
+        
+            + Added JPEG "save" and "draft" support for mode "YCbCr" images.
+              Note that if you save an "YCbCr" image as a JPEG file and read
+              it back, it is read as an RGB file.  To get around this, you
+              can use the "draft" method:
+        
+                im = Image.open("color.jpg")
+                im.draft("YCbCr", im.size)
+        
+            + Read "RGBA" TGA images.  Also fixed the orientation bug; all
+              images should now come out the right way.
+        
+            + Changed mode name (and internal representation) from "YCrCb"
+              to "YCbCr" (!)
+              *** WARNING: MAY BREAK EXISTING CODE ***
+        
+            (0.3b1 released)
+        
+            The test suite includes 750 individual tests.
+        
+            + The "pilfont" package is now included in the standard PIL
+              distribution.  The pilfont utility can be used to convert
+              X BDF and PCF raster font files to a format understood by
+              the ImageFont module.
+        
+            + GIF files are now interlaced by default.  To write a
+              non-interlaced file, pass interlace=0 to the "save"
+              method.
+        
+            + The default string format has changed for the "fromstring"
+              and "tostring" methods.
+              *** WARNING: MAY BREAK EXISTING CODE ***
+        
+              NOTE: If no extra arguments are given, the first line in
+              the string buffer is the top line of the image, instead of
+              the bottom line.  For RGB images, the string now contains
+              3 bytes per pixel instead of 4.  These changes were made
+              to make the methods compatible with the "fromstring"
+              factory function.
+        
+              To get the old behaviour, use the following syntax:
+        
+                data = im.tostring("raw", "RGBX", 0, -1)
+                im.fromstring(data, "raw", "RGBX", 0, -1)
+        
+            + "new" no longer gives a MemoryError if the width or height
+              is zero (this only happened on platforms where malloc(0)
+              or calloc(0) returns NULL).
+        
+            + "new" now adds a default palette object to "P" images.
+        
+            + You can now convert directly between all modes supported by
+              PIL.  When converting colour images to "P", PIL defaults to
+              a "web" palette and dithering.  When converting greyscale
+              images to "1", PIL uses a thresholding and dithering.
+        
+            + Added a "dither" option to "convert".  By default, "convert"
+              uses floyd-steinberg error diffusion for "P" and "1" targets,
+              so this option is only used to *disable* dithering. Allowed
+              values are NONE (no dithering) or FLOYDSTEINBERG (default).
+        
+                imOut = im.convert("P", dither=Image.NONE)
+        
+            + Added a full set of "I" decoders.  You can use "fromstring"
+              (and file decoders) to read any standard integer type as an
+              "I" image.
+        
+            + Added some support for "YCbCr" images (creation, conversion
+              from/to "L" and "RGB", IM YCC load/save)
+        
+            + "getpixel" now works properly with fractional coordinates.
+        
+            + ImageDraw "setink" now works with "I", "F", "RGB", "RGBA",
+              "RGBX", "CMYK", and "YCbCr" images.
+        
+            + ImImagePlugin no longer attaches palettes to "RGB" images.
+        
+            + Various minor fixes.
+        
+            (0.3a4 released)
+        
+            + Added experimental IPTC/NAA support.
+        
+            + Eliminated AttributeError exceptions after "crop" (from
+              Skip Montanaro)
+        
+            + Reads some uncompressed formats via memory mapping (this
+              is currently supported on Win32 only)
+        
+            + Fixed some last minute glitches in the last alpha release
+              (Types instead of types in Image.py, version numbers, etc.)
+        
+            + Eliminated some more bogus compiler warnings.
+        
+            + Various fixes to make PIL compile and run smoother on Macs
+              (from Jack Jansen).
+        
+            + Fixed "fromstring" and "tostring" for mode "I" images.
+        
+            (0.3a3 released)
+        
+            The test suite includes 530 individual tests.
+        
+            + Eliminated unexpected side-effect in "paste" with matte.  "paste"
+              now works properly also if compiled with "gcc".
+        
+            + Adapted to Python 1.5 (build issues only)
+        
+            + Fixed the ImageDraw "point" method to draw also the last
+              point (!).
+        
+            + Added "I" and "RGBX" support to Image.new.
+        
+            + The plugin path is now properly prepended to the module search
+              path when a plugin module is imported.
+        
+            + Added "draw" method to the ImageWin.Dib class.  This is used by
+              Topaz to print images on Windows printers.
+        
+            + "convert" now supports conversions from "P" to "1" and "F".
+        
+            + "paste" can now take a colour instead of an image as the first argument.
+              The colour must match the colour argument given to the new function, and
+              match the mode of the target image.
+        
+            + Fixed "paste" to allow a mask also for mode "F" images.
+        
+            + The BMP driver now saves mode "1" images.  When loading images, the mode
+              is set to "L" for 8-bit files with greyscale palettes, and to "P" for
+              other 8-bit files.
+        
+            + The IM driver now reads and saves "1" images (file modes "0 1" or "L 1").
+        
+            + The JPEG and GIF drivers now saves "1" images.  For JPEG, the image
+              is saved as 8-bit greyscale (it will load as mode "L").  For GIF, the
+              image will be loaded as a "P" image.
+        
+            + Fixed a potential buffer overrun in the GIF encoder.
+        
+            (0.3a2 released)
+        
+            The test suite includes 400 individual tests.
+        
+            + Improvements to the test suite revealed a number of minor bugs, which
+              are all fixed.  Note that crop/paste, 32-bit ImageDraw, and ImageFont
+              are still weak spots in this release.
+        
+            + Added "putpalette" method to the Image class.  You can use this
+              to add or modify the palette for "P" and "L" images.  If a palette
+              is added to an "L" image, it is automatically converted to a "P"
+              image.
+        
+            + Fixed ImageDraw to properly handle 32-bit image memories
+              ("RGB", "RGBA", "CMYK", "F")
+        
+            + Fixed "fromstring" and "tostring" not to mess up the mode attribute
+              in default mode.
+        
+            + Changed ImPlatform.h to work on CRAY's (don't have one at home, so I
+              haven't tried it).  The previous version assumed that either "short"
+              or "int" were 16-bit wide. PIL still won't compile on platforms where
+              neither "short", "int" nor "long" are 32-bit wide.
+        
+            + Added file= and data= keyword arguments to PhotoImage and BitmapImage.
+              This allows you to use them as drop-in replacements for the corre-
+              sponding Tkinter classes.
+        
+            + Removed bogus references to the crack coder (ImagingCrack).
+        
+            (0.3a1 released)
+        
+            + Make sure image is loaded in "tostring".
+        
+            + Added floating point packer (native 32-bit floats only).
+        
+            *** Changes from release 0.1b1 to 0.2 (b5) ***
+        
+            + Modified "fromstring" and "tostring" methods to use file codecs.
+              Also added "fromstring" factory method to create an image directly
+              from data in a string.
+        
+            + Added support for 32-bit floating point images (mode "F").  You
+              can convert between "L" and "F" images, and apply a subset of the
+              available image processing methods on the "F" image.  You can also
+              read virtually any data format into a floating point image memory;
+              see the section on "Decoding Floating Point Data" in the handbook
+              for more information.
+        
+            (0.2b5 released; on windows only)
+        
+            + Fixed the tobitmap() method to work properly for small bitmaps.
+        
+            + Added RMS and standard deviation to the ImageStat.Stat class.  Also
+              modified the constructor to take an optional feature mask, and also
+              to accept either an image or a list containing the histogram data.
+        
+            + The BitmapImage code in ImageTk can now use a special bitmap
+              decoder, which has to be patched into Tk.  See the "Tk/pilbitmap.txt"
+              file for details.  If not installed, bitmaps are transferred to Tk as
+              XBM strings.
+        
+            + The PhotoImage code in ImageTk now uses a Tcl command ("PyImagingPaste")
+              instead of a special image type.  This gives somewhat better performance,
+              and also allows PIL to support transparency.
+              *** WARNING: TKAPPINIT MUST BE MODIFIED ***
+        
+            + ImageTk now honours the alpha layer in RGBA images.  Only fully
+              transparent pixels are made transparent (that is, the alpha layer
+              is treated as a mask).  To treat the alpha laters as a matte, you
+              must paste the image on the background before handing it over to
+              ImageTk.
+        
+            + Added McIdas reader (supports 8-bit images only).
+        
+            + PIL now preloads drivers for BMP, GIF, JPEG, PPM, and TIFF.  As
+              long as you only load and save these formats, you don't have to
+              wait for a full scan for drivers.  To force scanning, call the
+              Image.init() function.
+        
+            + The "seek" and "tell" methods are now always available, also for
+              single-frame images.
+        
+            + Added optional mask argument to histogram method.  The mask may
+              be an "1" or "L" image with the same size as the original image.
+              Only pixels where the mask is non-zero are included in the
+              histogram.
+        
+            + The "paste" method now allows you to specify only the lower left
+              corner (a 2-tuple), instead of the full region (a 4-tuple).
+        
+            + Reverted to old plugin scanning model; now scans all directory
+              names in the path when looking for plugins.
+        
+            + Added PIXAR raster support.  Only uncompressed ("dumped") RGB
+              images can currently be read (based on information provided
+              by Greg Coats).
+        
+            + Added FlashPix (FPX) read support.  Reads all pixel formats, but
+              only the highest resolution is read, and the viewing transform is
+              currently ignored.
+        
+            + Made PNG encoding somewhat more efficient in "optimize" mode; a
+              bug in 0.2b4 didn't enable all predictor filters when optimized
+              storage were requested.
+        
+            + Added Microsoft Image Composer (MIC) read support.  When opened,
+              the first sprite in the file is loaded.  You can use the seek method
+              to load additional sprites from the file.
+        
+            + Properly reads "P" and "CMYK" PSD images.
+        
+            + "pilconvert" no longer optimizes by default; use the -o option to
+              make the file as small as possible (at the expense of speed); use
+              the -q option to set the quality when compressing to JPEG.
+        
+            + Fixed "crop" not to drop the palette for "P" images.
+        
+            + Added and verified FLC support.
+        
+            + Paste with "L" or "RGBA" alpha is now several times faster on most
+              platforms.
+        
+            + Changed Image.new() to initialize the image to black, as described
+              in the handbook.  To get an uninitialized image, use None as the
+              colour.
+        
+            + Fixed the PDF encoder to produce a valid header; Acrobat no longer
+              complains when you load PDF images created by PIL.
+        
+            + PIL only scans fully-qualified directory names in the path when
+              looking for plugins.
+              *** WARNING: MAY BREAK EXISTING CODE ***
+        
+            + Faster implementation of "save" used when filename is given,
+              or when file object has "fileno" and "flush" methods.
+        
+            + Don't crash in "crop" if region extends outside the source image.
+        
+            + Eliminated a massive memory leak in the "save" function.
+        
+            + The GIF decoder doesn't crash if the code size is set to an illegal
+              value.  This could happen since another bug didn't handle local
+              palettes properly if they didn't have the same size as the
+              global palette (not very common).
+        
+            + Added predictor support (TIFF 6.0 section 14) to the TIFF decoder.
+        
+            + Fixed palette and padding problems in BMP driver.  Now properly
+              writes "1", "L", "P" and "RGB" images.
+        
+            + Fixed getpixel()/getdata() to return correct pixel values.
+        
+            + Added PSD (PhotoShop) read support.  Reads both uncompressed
+              and compressed images of most types.
+        
+            + Added GIF write support (writes "uncompressed" GIF files only,
+              due to unresolvable licensing issues).  The "gifmaker.py" script
+              can be used to create GIF animations.
+        
+            + Reads 8-bit "L" and "P" TGA images.  Also reads 16-bit "RGB"
+              images.
+        
+            + Added FLI read support.  This driver has only been tested
+              on a few FLI samples.
+        
+            + Reads 2-bit and 4-bit PCX images.
+        
+            + Added MSP read and write support.  Both version 1 and 2 can be
+              read, but only version 1 (uncompressed) files are written.
+        
+            + Fixed a bug in the FLI/FLC identification code that caused the
+              driver to raise an exception when parsing valid FLI/FLC files.
+        
+            + Improved performance when loading file format plugins, and when
+              opening files.
+        
+            + Added GIF animation support, via the "seek" and "tell" methods.
+              You can use "player.py" to play an animated GIF file.
+        
+            + Removed MNG support, since the spec is changing faster than I
+              can change the code.  I've added support for the experimental
+              ARG format instead.  Contact me for more information on this
+              format.
+        
+            + Added keyword options to the "save" method.  The following options
+              are currently supported:
+        
+                  format	option		description
+                  --------------------------------------------------------
+                  JPEG	optimize	minimize output file at the
+                            expense of compression speed.
+        
+                  JPEG	progressive	enable progressive output. the
+                            option value is ignored.
+        
+                  JPEG	quality		set compression quality (1-100).
+                            the default value is 75.
+        
+                  JPEG	smooth		smooth dithered images.  value
+                            is strengh (1-100).  default is
+                            off (0).
+        
+                  PNG	optimize	minimize output file at the
+                            expense of compression speed.
+        
+              Expect more options in future releases.  Also note that
+              file writers silently ignore unknown options.
+        
+            + Plugged memory leaks in the PNG and TIFF decoders.
+        
+            + Added PNG write support.
+        
+            + (internal) RGB unpackers and converters now set the pad byte
+              to 255 (full opacity).
+        
+            + Properly handles the "transparency" property for GIF, PNG
+              and XPM files.
+        
+            + Added a "putalpha" method, allowing you to attach a "1" or "L"
+              image as the alpha layer to an "RGBA" image.
+        
+            + Various improvements to the sample scripts:
+        
+              "pilconvert"  Carries out some extra tricks in order to make
+                    the resulting file as small as possible.
+        
+              "explode"	(NEW) Split an image sequence into individual frames.
+        
+              "gifmaker"	(NEW) Convert a sequence file into a GIF animation.
+                    Note that the GIF encoder create "uncompressed" GIF
+                    files, so animations created by this script are
+                    rather large (typically 2-5 times the compressed
+                    sizes).
+        
+              "image2py"	(NEW) Convert a single image to a python module.  See
+                    comments in this script for details.
+        
+              "player"	If multiple images are given on the command line,
+                    they are interpreted as frames in a sequence.  The
+                    script assumes that they all have the same size.
+                    Also note that this script now can play FLI/FLC
+                    and GIF animations.
+        
+                    This player can also execute embedded Python
+                    animation applets (ARG format only).
+        
+              "viewer"	Transparent images ("P" with transparency property,
+                    and "RGBA") are superimposed on the standard Tk back-
+                    ground.
+        
+            + Fixed colour argument to "new".  For multilayer images, pass a
+              tuple: (Red, Green, Blue), (Red, Green, Blue, Alpha), or (Cyan,
+              Magenta, Yellow, Black).
+        
+            + Added XPM (X pixmap) read support.
+        
+            (0.2b3 released)
+        
+            + Added MNG (multi-image network graphics) read support.  "Ming"
+              is a proposed animation standard, based on the PNG file format.
+        
+              You can use the "player" sample script to display some flavours
+              of this format.  The MNG standard is still under development,
+              as is this driver.  More information, including sample files,
+              can be found at <ftp://swrinde.nde.swri.edu/pub/mng>
+        
+            + Added a "verify" method to images loaded from file.  This method
+              scans the file for errors, without actually decoding the image
+              data, and raises a suitable exception if it finds any problems.
+              Currently implemented for PNG and MNG files only.
+        
+            + Added support for interlaced GIF images.
+        
+            + Added PNG read support -- if linked with the ZLIB compression library,
+              PIL reads all kinds of PNG images, except interlaced files.
+        
+            + Improved PNG identification support -- doesn't mess up on unknown
+              chunks, identifies all possible PNG modes, and verifies checksum
+              on PNG header chunks.
+        
+            + Added an experimental reader for placable Windows Meta Files (WMF).
+              This reader is still very incomplete, but it illustrates how PIL's
+              drawing capabilities can be used to render vector and metafile
+              formats.
+        
+            + Added restricted drivers for images from Image Tools (greyscale
+              only) and LabEye/IFUNC (common interchange modes only).
+        
+            + Some minor improvements to the sample scripts provided in the
+              "Scripts" directory.
+        
+            + The test images have been moved to the "Images" directory.
+        
+            (0.2b2 released)
+            (0.2b1 released; Windows only)
+        
+            + Fixed filling of complex polygons.  The ImageDraw "line" and
+              "polygon" methods also accept Path objects.
+        
+            + The ImageTk "PhotoImage" object can now be constructed directly
+              from an image.  You can also pass the object itself to Tkinter,
+              instead of using the "image" attribute.  Finally, using "paste"
+              on a displayed image automatically updates the display.
+        
+            + The ImageTk "BitmapImage" object allows you to create transparent
+              overlays from 1-bit images.  You can pass the object itself to
+              Tkinter.  The constructor takes the same arguments as the Tkinter
+              BitmapImage class; use the "foreground" option to set the colour
+              of the overlay.
+        
+            + Added a "putdata" method to the Image class.  This can be used to
+              load a 1-layer image with data from a sequence object or a string.
+              An optional floating point scale and offset can be used to adjust
+              the data to fit into the 8-bit pixel range.  Also see the "getdata"
+              method.
+        
+            + Added the EXTENT method to the Image "transform" method.  This can
+              be used to quickly crop, stretch, shrink, or mirror a subregion
+              from another image.
+        
+            + Adapted to Python 1.4.
+        
+            + Added a project makefile for Visual C++ 4.x.  This allows you to
+              easily build a dynamically linked version of PIL for Windows 95
+              and NT.
+        
+            + A Tk "booster" patch for Windows is available.  It gives dramatic
+              performance improvements for some displays.  Has been tested with
+              Tk 4.2 only, but is likely to work with Tk 4.1 as well.  See the Tk
+              subdirectory for details.
+        
+            + You can now save 1-bit images in the XBM format.  In addition, the
+              Image class now provides a "tobitmap" method which returns a string
+              containing an XBM representation of the image.  Quite handy to use
+              with Tk.
+        
+            + More conversions, including "RGB" to "1" and more.
+        
+            (0.2a1 released)
+        
+            + Where earlier versions accepted lists, this version accepts arbitrary
+              Python sequences (including strings, in some cases).  A few resource
+              leaks were plugged in the process.
+        
+            + The Image "paste" method now allows the box to extend outside
+              the target image.  The size of the box, the image to be pasted,
+              and the optional mask must still match.
+        
+            + The ImageDraw module now supports filled polygons, outlined and
+              filled ellipses, and text.  Font support is rudimentary, though.
+        
+            + The Image "point" method now takes an optional mode argument,
+              allowing you to convert the image while translating it.  Currently,
+              this can only be used to convert "L" or "P" images to "1" images
+              (creating thresholded images or "matte" masks).
+        
+            + An Image "getpixel" method has been added.  For single band images,
+              it returns the pixel value at a given position as an integer.
+              For n-band images, it returns an n-tuple of integers.
+        
+            + An Image "getdata" method has been added.  It returns a sequence
+              object representing the image as a 1-dimensional array.  Only len()
+              and [] can be used with this sequence.  This method returns a
+              reference to the existing image data, so changes in the image
+              will be immediately reflected in the sequence object.
+        
+            + Fixed alignment problems in the Windows BMP writer.
+        
+            + If converting an "RGB" image to "RGB" or "L", you can give a second
+              argument containing a colour conversion matrix.
+        
+            + An Image "getbbox" method has been added.  It returns the bounding
+              box of data in an image, considering the value 0 as background.
+        
+            + An Image "offset" method has been added.  It returns a new image
+              where the contents of the image have been offset the given distance
+              in X and/or Y direction.  Data wraps between edges.
+        
+            + Saves PDF images.  The driver creates a binary PDF 1.1 files, using
+              JPEG compression for "L", "RGB", and "CMYK" images, and hex encoding
+              (same as for PostScript) for other formats.
+        
+            + The "paste" method now accepts "1" masks.  Zero means transparent,
+              any other pixel value means opaque.  This is faster than using an
+              "L" transparency mask.
+        
+            + Properly writes EPS files (and properly prints images to postscript
+              printers as well).
+        
+            + Reads 4-bit BMP files, as well as 4 and 8-bit Windows ICO and CUR
+              files.  Cursor animations are not supported.
+        
+            + Fixed alignment problems in the Sun raster loader.
+        
+            + Added "draft" and "thumbnail" methods.  The draft method is used
+              to optimize loading of JPEG and PCD files, the thumbnail method is
+              used to create a thumbnail representation of an image.
+        
+            + Added Windows display support, via the ImageWin class (see the
+              handbook for details).
+        
+            + Added raster conversion for EPS files.  This requires GNU or Aladdin
+              Ghostscript, and probably works on UNIX only.
+        
+            + Reads PhotoCD (PCD) images.  The base resolution (768x512) can be
+              read from a PhotoCD file.
+        
+            + Eliminated some compiler warnings.  Bindings now compile cleanly in C++
+              mode.  Note that the Imaging library itself must be compiled in C mode.
+        
+            + Added "bdf2pil.py", which converts BDF fonts into images with associated
+              metrics.  This is definitely work in progress.  For info, see description
+              in script for details.
+        
+            + Fixed a bug in the "ImageEnhance.py" module.
+        
+            + Fixed a bug in the netpbm save hack in "GifImagePlugin.py"
+        
+            + Fixed 90 and 270 degree rotation of rectangular images.
+        
+            + Properly reads 8-bit TIFF palette-color images.
+        
+            + Reads plane separated RGB and CMYK TIFF images.
+        
+            + Added driver debug mode.  This is enabled by setting Image.DEBUG
+              to a non-zero value.  Try the -D option to "pilfile.py" and see what
+              happens.
+        
+            + Don't crash on "atend" constructs in PostScript files.
+        
+            + Only the Image module imports _imaging directly.  Other modules
+              should refer to the binding module as "Image.core".
+        
+            *** Changes from release 0.0 to 0.1 (b1) ***
+        
+            + A handbook is available (distributed separately).
+        
+            + The coordinate system is changed so that (0,0) is now located
+              in the upper left corner.  This is in compliancy with ISO 12087
+              and 90% of all other image processing and graphics libraries.
+        
+            + Modes "1" (bilevel) and "P" (palette) have been introduced.  Note
+              that bilevel images are stored with one byte per pixel.
+        
+            + The Image "crop" and "paste" methods now accepts None as the
+              box argument, to refer to the full image (self, that is).
+        
+            + The Image "crop" method now works properly.
+        
+            + The Image "point" method is now available.  You can use either a
+              lookup table or a function taking one argument.
+        
+            + The Image join function has been renamed to "merge".
+        
+            + An Image "composite" function has been added.  It is identical
+              to copy() followed by paste(mask).
+        
+            + An Image "eval" function has been added.  It is currently identical
+              to point(function); that is, only a single image can be processed.
+        
+            + A set of channel operations has been added.  See the "ImageChops"
+              module, test_chops.py, and the handbook for details.
+        
+            + Added the "pilconvert" utility, which converts image files.  Note
+              that the number of output formats are still quite restricted.
+        
+            + Added the "pilfile" utility, which quickly identifies image files
+              (without loading them, in most cases).
+        
+            + Added the "pilprint" utility, which prints image files to Postscript
+              printers.
+        
+            + Added a rudimentary version of the "pilview" utility, which is
+              simple image viewer based on Tk.  Only File/Exit and Image/Next
+              works properly.
+        
+            + An interface to Tk has been added.  See "Lib/ImageTk.py" and README
+              for details.
+        
+            + An interface to Jack Jansen's Img library has been added (thanks to
+              Jack).  This allows you to read images through the Img extensions file
+              format handlers.  See the file "Lib/ImgExtImagePlugin.py" for details.
+        
+            + Postscript printing is provided through the PSDraw module.  See the
+              handbook for details.

+Description: SQLAlchemy
+        ==========
+        
+        The Python SQL Toolkit and Object Relational Mapper
+        
+        Introduction
+        -------------
+        
+        SQLAlchemy is the Python SQL toolkit and Object Relational Mapper
+        that gives application developers the full power and
+        flexibility of SQL. SQLAlchemy provides a full suite
+        of well known enterprise-level persistence patterns,
+        designed for efficient and high-performing database
+        access, adapted into a simple and Pythonic domain
+        language.
+        
+        Major SQLAlchemy features include:
+        
+        * An industrial strength ORM, built 
+          from the core on the identity map, unit of work,
+          and data mapper patterns.   These patterns
+          allow transparent persistence of objects 
+          using a declarative configuration system.
+          Domain models
+          can be constructed and manipulated naturally,
+          and changes are synchronized with the
+          current transaction automatically.
+        * A relationally-oriented query system, exposing
+          the full range of SQL's capabilities 
+          explicitly, including joins, subqueries, 
+          correlation, and most everything else, 
+          in terms of the object model.
+          Writing queries with the ORM uses the same 
+          techniques of relational composition you use 
+          when writing SQL.  While you can drop into
+          literal SQL at any time, it's virtually never
+          needed.
+        * A comprehensive and flexible system 
+          of eager loading for related collections and objects.
+          Collections are cached within a session,
+          and can be loaded on individual access, all 
+          at once using joins, or by query per collection
+          across the full result set.
+        * A Core SQL construction system and DBAPI 
+          interaction layer.  The SQLAlchemy Core is
+          separate from the ORM and is a full database
+          abstraction layer in its own right, and includes
+          an extensible Python-based SQL expression 
+          language, schema metadata, connection pooling, 
+          type coercion, and custom types.
+        * All primary and foreign key constraints are 
+          assumed to be composite and natural.  Surrogate
+          integer primary keys are of course still the 
+          norm, but SQLAlchemy never assumes or hardcodes
+          to this model.
+        * Database introspection and generation.  Database
+          schemas can be "reflected" in one step into
+          Python structures representing database metadata;
+          those same structures can then generate 
+          CREATE statements right back out - all within
+          the Core, independent of the ORM.
+        
+        SQLAlchemy's philosophy:
+        
+        * SQL databases behave less and less like object
+          collections the more size and performance start to
+          matter; object collections behave less and less like
+          tables and rows the more abstraction starts to matter.
+          SQLAlchemy aims to accommodate both of these
+          principles.
+        * An ORM doesn't need to hide the "R".   A relational
+          database provides rich, set-based functionality
+          that should be fully exposed.   SQLAlchemy's
+          ORM provides an open-ended set of patterns
+          that allow a developer to construct a custom
+          mediation layer between a domain model and 
+          a relational schema, turning the so-called
+          "object relational impedance" issue into
+          a distant memory.
+        * The developer, in all cases, makes all decisions
+          regarding the design, structure, and naming conventions
+          of both the object model as well as the relational
+          schema.   SQLAlchemy only provides the means
+          to automate the execution of these decisions.
+        * With SQLAlchemy, there's no such thing as 
+          "the ORM generated a bad query" - you 
+          retain full control over the structure of 
+          queries, including how joins are organized,
+          how subqueries and correlation is used, what 
+          columns are requested.  Everything SQLAlchemy
+          does is ultimately the result of a developer-
+          initiated decision.
+        * Don't use an ORM if the problem doesn't need one.
+          SQLAlchemy consists of a Core and separate ORM
+          component.   The Core offers a full SQL expression
+          language that allows Pythonic construction 
+          of SQL constructs that render directly to SQL
+          strings for a target database, returning
+          result sets that are essentially enhanced DBAPI
+          cursors.
+        * Transactions should be the norm.  With SQLAlchemy's
+          ORM, nothing goes to permanent storage until
+          commit() is called.  SQLAlchemy encourages applications
+          to create a consistent means of delineating
+          the start and end of a series of operations.
+        * Never render a literal value in a SQL statement.
+          Bound parameters are used to the greatest degree
+          possible, allowing query optimizers to cache 
+          query plans effectively and making SQL injection
+          attacks a non-issue.

+        
+        ``cryptography`` is a package which provides cryptographic recipes and
+        primitives to Python developers.  Our goal is for it to be your "cryptographic
+        standard library". It supports Python 2.6-2.7, Python 3.2+, and PyPy.
+        
+        ``cryptography`` includes both high level recipes, and low level interfaces to
+        common cryptographic algorithms such as symmetric ciphers, message digests and
+        key derivation functions. For example, to encrypt something with
+        ``cryptography``'s high level symmetric encryption recipe:
+        
+        .. code-block:: pycon
+        
+            >>> from cryptography.fernet import Fernet
+            >>> # Put this somewhere safe!
+            >>> key = Fernet.generate_key()
+            >>> f = Fernet(key)
+            >>> token = f.encrypt(b"A really secret message. Not for prying eyes.")
+            >>> token
+            '...'
+            >>> f.decrypt(token)
+            'A really secret message. Not for prying eyes.'
+        
+        You can find more information in the `documentation`_.
+        
+        Discussion
+        ~~~~~~~~~~
+        
+        If you run into bugs, you can file them in our `issue tracker`_.
+        
+        We maintain a `cryptography-dev`_ mailing list for development discussion.
+        
+        You can also join ``#cryptography-dev`` on Freenode to ask questions or get
+        involved.

+Summary: Ed25519 public-key signatures
+Home-page: https://github.com/warner/python-ed25519
+Author: Brian Warner
+Author-email: warner-python-ed25519@lothar.com
+License: MIT
+Description: Python bindings to the Ed25519 public-key signature system.
+        
+        This offers a comfortable python interface to a C implementation of the
+        Ed25519 public-key signature system (http://ed25519.cr.yp.to/), using the
+        portable 'ref' code from the 'SUPERCOP' benchmarking suite.
+        
+        This system provides high (128-bit) security, short (32-byte) keys, short
+        (64-byte) signatures, and fast (2-6ms) operation. Please see the README for
+        more details.

+Package resource API
+--------------------
+
+A resource is a logical file contained within a package, or a logical
+subdirectory thereof.  The package resource API expects resource names
+to have their path parts separated with ``/``, *not* whatever the local
+path separator is.  Do not use os.path operations to manipulate resource
+names being passed into the API.
+
+The package resource API is designed to work with normal filesystem packages,
+.egg files, and unpacked .egg files.  It can also work in a limited way with
+.zip files and with custom PEP 302 loaders that support the ``get_data()``
+method.

+===============================
+Installing and Using Setuptools
+===============================
+
+.. contents:: **Table of Contents**
+
+
+-------------------------
+Installation Instructions
+-------------------------
+
+The recommended way to bootstrap setuptools on any system is to download
+`ez_setup.py`_ and run it using the target Python environment. Different
+operating systems have different recommended techniques to accomplish this
+basic routine, so below are some examples to get you started.
+
+Setuptools requires Python 2.6 or later. To install setuptools
+on Python 2.4 or Python 2.5, use the `bootstrap script for Setuptools 1.x
+<https://bitbucket.org/pypa/setuptools/raw/bootstrap-py24/ez_setup.py>`_.
+
+The link provided to ez_setup.py is a bookmark to bootstrap script for the
+latest known stable release.

+.. _ez_setup.py: https://bootstrap.pypa.io/ez_setup.py
+
+Windows (Powershell 3 or later)
+===============================
+
+For best results, uninstall previous versions FIRST (see `Uninstalling`_).
+
+Using Windows 8 (which includes PowerShell 3) or earlier versions of Windows
+with PowerShell 3 installed, it's possible to install with one simple
+Powershell command. Start up Powershell and paste this command::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python -
+
+You must start the Powershell with Administrative privileges or you may choose
+to install a user-local installation::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python - --user
+
+If you have Python 3.3 or later, you can use the ``py`` command to install to
+different Python versions. For example, to install to Python 3.3 if you have
+Python 2.7 installed::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | py -3 -
+
+The recommended way to install setuptools on Windows is to download
+`ez_setup.py`_ and run it. The script will download the appropriate
+distribution file and install it for you.
+
+Once installation is complete, you will find an ``easy_install`` program in
+your Python ``Scripts`` subdirectory.  For simple invocation and best results,
+add this directory to your ``PATH`` environment variable, if it is not already
+present. If you did a user-local install, the ``Scripts`` subdirectory is
+``$env:APPDATA\Python\Scripts``.
+
+
+Windows (simplified)
+====================
+
+For Windows without PowerShell 3 or for installation without a command-line,
+download `ez_setup.py`_ using your preferred web browser or other technique
+and "run" that file.
+
+
+Unix (wget)
+===========
+
+Most Linux distributions come with wget.
+
+Download `ez_setup.py`_ and run it using the target Python version. The script
+will download the appropriate version and install it for you::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | python
+
+Note that you will may need to invoke the command with superuser privileges to
+install to the system Python::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
+
+Alternatively, Setuptools may be installed to a user-local path::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | python - --user
+
+Unix including Mac OS X (curl)
+==============================
+
+If your system has curl installed, follow the ``wget`` instructions but
+replace ``wget`` with ``curl`` and ``-O`` with ``-o``. For example::
+
+    > curl https://bootstrap.pypa.io/ez_setup.py -o - | python
+
+
+Advanced Installation
+=====================
+
+For more advanced installation options, such as installing to custom
+locations or prefixes, download and extract the source
+tarball from `Setuptools on PyPI <https://pypi.python.org/pypi/setuptools>`_
+and run setup.py with any supported distutils and Setuptools options.
+For example::
+
+    setuptools-x.x$ python setup.py install --prefix=/opt/setuptools
+
+Use ``--help`` to get a full options list, but we recommend consulting
+the `EasyInstall manual`_ for detailed instructions, especially `the section
+on custom installation locations`_.

+
+Downloads
+=========
+
+All setuptools downloads can be found at `the project's home page in the Python
+Package Index`_.  Scroll to the very bottom of the page to find the links.
+
+.. _the project's home page in the Python Package Index: https://pypi.python.org/pypi/setuptools
+
+In addition to the PyPI downloads, the development version of ``setuptools``
+is available from the `Bitbucket repo`_, and in-development versions of the
+`0.6 branch`_ are available as well.
+
+.. _Bitbucket repo: https://bitbucket.org/pypa/setuptools/get/default.tar.gz#egg=setuptools-dev
+.. _0.6 branch: http://svn.python.org/projects/sandbox/branches/setuptools-0.6/#egg=setuptools-dev06
+
+Uninstalling
+============
+
+On Windows, if Setuptools was installed using an ``.exe`` or ``.msi``
+installer, simply use the uninstall feature of "Add/Remove Programs" in the
+Control Panel.
+
+Otherwise, to uninstall Setuptools or Distribute, regardless of the Python
+version, delete all ``setuptools*`` and ``distribute*`` files and
+directories from your system's ``site-packages`` directory
+(and any other ``sys.path`` directories) FIRST.
+
+If you are upgrading or otherwise plan to re-install Setuptools or Distribute,
+nothing further needs to be done. If you want to completely remove Setuptools,
+you may also want to remove the 'easy_install' and 'easy_install-x.x' scripts
+and associated executables installed to the Python scripts directory.
+

+
+* The original design for the ``.egg`` format and the ``pkg_resources`` API was
+  co-created by Phillip Eby and Bob Ippolito.  Bob also implemented the first
+  version of ``pkg_resources``, and supplied the OS X operating system version
+  compatibility algorithm.
+
+* Ian Bicking implemented many early "creature comfort" features of
+  easy_install, including support for downloading via Sourceforge and
+  Subversion repositories.  Ian's comments on the Web-SIG about WSGI
+  application deployment also inspired the concept of "entry points" in eggs,
+  and he has given talks at PyCon and elsewhere to inform and educate the
+  community about eggs and setuptools.
+
+* Jim Fulton contributed time and effort to build automated tests of various
+  aspects of ``easy_install``, and supplied the doctests for the command-line
+  ``.exe`` wrappers on Windows.
+
+* Phillip J. Eby is the seminal author of setuptools, and
+  first proposed the idea of an importable binary distribution format for
+  Python application plug-ins.
+
+* Significant parts of the implementation of setuptools were funded by the Open
+  Source Applications Foundation, to provide a plug-in infrastructure for the
+  Chandler PIM application.  In addition, many OSAF staffers (such as Mike
+  "Code Bear" Taylor) contributed their time and stress as guinea pigs for the
+  use of eggs and setuptools, even before eggs were "cool".  (Thanks, guys!)
+
+* Tarek Ziadé is the principal author of the Distribute fork, which
+  re-invigorated the community on the project, encouraged renewed innovation,
+  and addressed many defects.
+
+* Since the merge with Distribute, Jason R. Coombs is the
+  maintainer of setuptools.  The project is maintained in coordination with
+  the Python Packaging Authority (PyPA) and the larger Python community.

+
+-----
+6.0.2
+-----
+
+* `Issue #262 <https://bitbucket.org/pypa/setuptools/issue/262>`_: Fixed regression in pip install due to egg-info directories
+  being omitted. Re-opens `Issue #118 <https://bitbucket.org/pypa/setuptools/issue/118>`_.
+
+-----
+6.0.1
+-----
+
+* `Issue #259 <https://bitbucket.org/pypa/setuptools/issue/259>`_: Fixed regression with namespace package handling on ``single
+  version, externally managed`` installs.
+
+---
+6.0
+---
+
+* `Issue #100 <https://bitbucket.org/pypa/setuptools/issue/100>`_: When building a distribution, Setuptools will no longer match
+  default files using platform-dependent case sensitivity, but rather will
+  only match the files if their case matches exactly. As a result, on Windows
+  and other case-insensitive file systems, files with names such as
+  'readme.txt' or 'README.TXT' will be omitted from the distribution and a
+  warning will be issued indicating that 'README.txt' was not found. Other
+  filenames affected are:
+
+    - README.rst
+    - README
+    - setup.cfg
+    - setup.py (or the script name)
+    - test/test*.py
+
+  Any users producing distributions with filenames that match those above
+  case-insensitively, but not case-sensitively, should rename those files in
+  their repository for better portability.
+* `Pull Request #72 <https://bitbucket.org/pypa/setuptools/pull-request/72>`_: When using ``single_version_externally_managed``, the
+  exclusion list now includes Python 3.2 ``__pycache__`` entries.
+* `Pull Request #76 <https://bitbucket.org/pypa/setuptools/pull-request/76>`_ and `Pull Request #78 <https://bitbucket.org/pypa/setuptools/pull-request/78>`_: lines in top_level.txt are now
+  ordered deterministically.
+* `Issue #118 <https://bitbucket.org/pypa/setuptools/issue/118>`_: The egg-info directory is now no longer included in the list
+  of outputs.
+* `Issue #258 <https://bitbucket.org/pypa/setuptools/issue/258>`_: Setuptools now patches distutils msvc9compiler to
+  recognize the specially-packaged compiler package for easy extension module
+  support on Python 2.6, 2.7, and 3.2.
+
+---
+5.8
+---
+
+* `Issue #237 <https://bitbucket.org/pypa/setuptools/issue/237>`_: ``pkg_resources`` now uses explicit detection of Python 2 vs.
+  Python 3, supporting environments where builtins have been patched to make
+  Python 3 look more like Python 2.
+
+---
+5.7
+---
+
+* `Issue #240 <https://bitbucket.org/pypa/setuptools/issue/240>`_: Based on real-world performance measures against 5.4, zip
+  manifests are now cached in all circumstances. The
+  ``PKG_RESOURCES_CACHE_ZIP_MANIFESTS`` environment variable is no longer
+  relevant. The observed "memory increase" referenced in the 5.4 release
+  notes and detailed in `Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154>`_ was likely not an increase over the status
+  quo, but rather only an increase over not storing the zip info at all.
+
+---
+5.6
+---
+
+* `Issue #242 <https://bitbucket.org/pypa/setuptools/issue/242>`_: Use absolute imports in svn_utils to avoid issues if the
+  installing package adds an xml module to the path.
+
+-----
+5.5.1
+-----
+
+* `Issue #239 <https://bitbucket.org/pypa/setuptools/issue/239>`_: Fix typo in 5.5 such that fix did not take.
+
+---
+5.5
+---
+
+* `Issue #239 <https://bitbucket.org/pypa/setuptools/issue/239>`_: Setuptools now includes the setup_requires directive on
+  Distribution objects and validates the syntax just like install_requires
+  and tests_require directives.
+
+-----
+5.4.2
+-----
+
+* `Issue #236 <https://bitbucket.org/pypa/setuptools/issue/236>`_: Corrected regression in execfile implementation for Python 2.6.
+
+-----
+5.4.1
+-----
+
+* `Python #7776 <http://bugs.python.org/issue7776>`_: (ssl_support) Correct usage of host for validation when
+  tunneling for HTTPS.
+
+---
+5.4
+---
+
+* `Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154>`_: ``pkg_resources`` will now cache the zip manifests rather than
+  re-processing the same file from disk multiple times, but only if the
+  environment variable ``PKG_RESOURCES_CACHE_ZIP_MANIFESTS`` is set. Clients
+  that package many modules in the same zip file will see some improvement
+  in startup time by enabling this feature. This feature is not enabled by
+  default because it causes a substantial increase in memory usage.
+
+---
+5.3
+---
+
+* `Issue #185 <https://bitbucket.org/pypa/setuptools/issue/185>`_: Make svn tagging work on the new style SVN metadata.
+  Thanks cazabon!
+* Prune revision control directories (e.g .svn) from base path
+  as well as sub-directories.
+
+---
+5.2
+---
+
+* Added a `Developer Guide
+  <https://pythonhosted.org/setuptools/developer-guide.html>`_ to the official
+  documentation.
+* Some code refactoring and cleanup was done with no intended behavioral
+  changes.
+* During install_egg_info, the generated lines for namespace package .pth
+  files are now processed even during a dry run.
+
+---
+5.1
+---
+
+* `Issue #202 <https://bitbucket.org/pypa/setuptools/issue/202>`_: Implemented more robust cache invalidation for the ZipImporter,
+  building on the work in `Issue #168 <https://bitbucket.org/pypa/setuptools/issue/168>`_. Special thanks to Jurko Gospodnetic and
+  PJE.
+
+-----
+5.0.2
+-----
+
+* `Issue #220 <https://bitbucket.org/pypa/setuptools/issue/220>`_: Restored script templates.
+
+-----
+5.0.1
+-----
+
+* Renamed script templates to end with .tmpl now that they no longer need
+  to be processed by 2to3. Fixes spurious syntax errors during build/install.
+
+---
+5.0
+---
+
+* `Issue #218 <https://bitbucket.org/pypa/setuptools/issue/218>`_: Re-release of 3.8.1 to signal that it supersedes 4.x.
+* Incidentally, script templates were updated not to include the triple-quote
+  escaping.
+
+-------------------------
+3.7.1 and 3.8.1 and 4.0.1
+-------------------------
+
+* `Issue #213 <https://bitbucket.org/pypa/setuptools/issue/213>`_: Use legacy StringIO behavior for compatibility under pbr.
+* `Issue #218 <https://bitbucket.org/pypa/setuptools/issue/218>`_: Setuptools 3.8.1 superseded 4.0.1, and 4.x was removed
+  from the available versions to install.
+
+---
+4.0
+---
+
+* `Issue #210 <https://bitbucket.org/pypa/setuptools/issue/210>`_: ``setup.py develop`` now copies scripts in binary mode rather
+  than text mode, matching the behavior of the ``install`` command.
+
+---
+3.8
+---
+
+* Extend `Issue #197 <https://bitbucket.org/pypa/setuptools/issue/197>`_ workaround to include all Python 3 versions prior to
+  3.2.2.
+
+---
+3.7
+---
+
+* `Issue #193 <https://bitbucket.org/pypa/setuptools/issue/193>`_: Improved handling of Unicode filenames when building manifests.
+

+3.5.2
+-----
+
+* `Issue #168 <https://bitbucket.org/pypa/setuptools/issue/168>`_: More robust handling of replaced zip files and stale caches.

+---
+
+* `Issue #195 <https://bitbucket.org/pypa/setuptools/issue/195>`_: Follow symbolic links in find_packages (restoring behavior
+  broken in 3.4).
+* `Issue #197 <https://bitbucket.org/pypa/setuptools/issue/197>`_: On Python 3.1, PKG-INFO is now saved in a UTF-8 encoding instead
+  of ``sys.getpreferredencoding`` to match the behavior on Python 2.6-3.4.
+* `Issue #192 <https://bitbucket.org/pypa/setuptools/issue/192>`_: Preferred bootstrap location is now
+  https://bootstrap.pypa.io/ez_setup.py (mirrored from former location).
+
+-----
+3.4.4
+-----
+
+* `Issue #184 <https://bitbucket.org/pypa/setuptools/issue/184>`_: Correct failure where find_package over-matched packages
+  when directory traversal isn't short-circuited.
+

+
+-----
+3.4.1
+-----
+
+* `Issue #180 <https://bitbucket.org/pypa/setuptools/issue/180>`_: Fix regression in test command not caught by py.test-run tests.
+
+---
+3.4
+---
+
+* `Issue #176 <https://bitbucket.org/pypa/setuptools/issue/176>`_: Add parameter to the test command to support a custom test
+  runner: --test-runner or -r.
+* `Issue #177 <https://bitbucket.org/pypa/setuptools/issue/177>`_: Now assume most common invocation to install command on
+  platforms/environments without stack support (issuing a warning). Setuptools
+  now installs naturally on IronPython. Behavior on CPython should be
+  unchanged.
+
+---
+3.3
+---
+
+* Add ``include`` parameter to ``setuptools.find_packages()``.
+
+---
+3.2
+---
+
+* `Pull Request #39 <https://bitbucket.org/pypa/setuptools/pull-request/39>`_: Add support for C++ targets from Cython ``.pyx`` files.
+* `Issue #162 <https://bitbucket.org/pypa/setuptools/issue/162>`_: Update dependency on certifi to 1.0.1.
+* `Issue #164 <https://bitbucket.org/pypa/setuptools/issue/164>`_: Update dependency on wincertstore to 0.2.
+
+---
+3.1
+---
+
+* `Issue #161 <https://bitbucket.org/pypa/setuptools/issue/161>`_: Restore Features functionality to allow backward compatibility
+  (for Features) until the uses of that functionality is sufficiently removed.
+
+-----
+3.0.2
+-----
+
+* Correct typo in previous bugfix.
+
+-----
+3.0.1
+-----
+
+* `Issue #157 <https://bitbucket.org/pypa/setuptools/issue/157>`_: Restore support for Python 2.6 in bootstrap script where
+  ``zipfile.ZipFile`` does not yet have support for context managers.
+
+---
+3.0
+---
+
+* `Issue #125 <https://bitbucket.org/pypa/setuptools/issue/125>`_: Prevent Subversion support from creating a ~/.subversion
+  directory just for checking the presence of a Subversion repository.
+* `Issue #12 <https://bitbucket.org/pypa/setuptools/issue/12>`_: Namespace packages are now imported lazily.  That is, the mere
+  declaration of a namespace package in an egg on ``sys.path`` no longer
+  causes it to be imported when ``pkg_resources`` is imported.  Note that this
+  change means that all of a namespace package's ``__init__.py`` files must
+  include a ``declare_namespace()`` call in order to ensure that they will be
+  handled properly at runtime.  In 2.x it was possible to get away without
+  including the declaration, but only at the cost of forcing namespace
+  packages to be imported early, which 3.0 no longer does.
+* `Issue #148 <https://bitbucket.org/pypa/setuptools/issue/148>`_: When building (bdist_egg), setuptools no longer adds
+  ``__init__.py`` files to namespace packages. Any packages that rely on this
+  behavior will need to create ``__init__.py`` files and include the
+  ``declare_namespace()``.
+* `Issue #7 <https://bitbucket.org/pypa/setuptools/issue/7>`_: Setuptools itself is now distributed as a zip archive in addition to
+  tar archive. ez_setup.py now uses zip archive. This approach avoids the potential
+  security vulnerabilities presented by use of tar archives in ez_setup.py.
+  It also leverages the security features added to ZipFile.extract in Python 2.7.4.
+* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Removed deprecated Features functionality.
+* `Pull Request #28 <https://bitbucket.org/pypa/setuptools/pull-request/28>`_: Remove backport of ``_bytecode_filenames`` which is
+  available in Python 2.6 and later, but also has better compatibility with
+  Python 3 environments.
+* `Issue #156 <https://bitbucket.org/pypa/setuptools/issue/156>`_: Fix spelling of __PYVENV_LAUNCHER__ variable.
+
+---
+2.2
+---
+
+* `Issue #141 <https://bitbucket.org/pypa/setuptools/issue/141>`_: Restored fix for allowing setup_requires dependencies to
+  override installed dependencies during setup.
+* `Issue #128 <https://bitbucket.org/pypa/setuptools/issue/128>`_: Fixed issue where only the first dependency link was honored
+  in a distribution where multiple dependency links were supplied.
+
+-----
+2.1.2
+-----
+
+* `Issue #144 <https://bitbucket.org/pypa/setuptools/issue/144>`_: Read long_description using codecs module to avoid errors
+  installing on systems where LANG=C.
+
+-----
+2.1.1
+-----
+
+* `Issue #139 <https://bitbucket.org/pypa/setuptools/issue/139>`_: Fix regression in re_finder for CVS repos (and maybe Git repos
+  as well).
+
+---
+2.1
+---
+
+* `Issue #129 <https://bitbucket.org/pypa/setuptools/issue/129>`_: Suppress inspection of ``*.whl`` files when searching for files
+  in a zip-imported file.
+* `Issue #131 <https://bitbucket.org/pypa/setuptools/issue/131>`_: Fix RuntimeError when constructing an egg fetcher.
+
+-----
+2.0.2
+-----
+
+* Fix NameError during installation with Python implementations (e.g. Jython)
+  not containing parser module.
+* Fix NameError in ``sdist:re_finder``.
+
+-----
+2.0.1
+-----
+
+* `Issue #124 <https://bitbucket.org/pypa/setuptools/issue/124>`_: Fixed error in list detection in upload_docs.
+
+---
+2.0
+---
+
+* `Issue #121 <https://bitbucket.org/pypa/setuptools/issue/121>`_: Exempt lib2to3 pickled grammars from DirectorySandbox.
+* `Issue #41 <https://bitbucket.org/pypa/setuptools/issue/41>`_: Dropped support for Python 2.4 and Python 2.5. Clients requiring
+  setuptools for those versions of Python should use setuptools 1.x.
+* Removed ``setuptools.command.easy_install.HAS_USER_SITE``. Clients
+  expecting this boolean variable should use ``site.ENABLE_USER_SITE``
+  instead.
+* Removed ``pkg_resources.ImpWrapper``. Clients that expected this class
+  should use ``pkgutil.ImpImporter`` instead.
+
+-----
+1.4.2
+-----
+
+* `Issue #116 <https://bitbucket.org/pypa/setuptools/issue/116>`_: Correct TypeError when reading a local package index on Python
+  3.
+
+-----
+1.4.1
+-----
+
+* `Issue #114 <https://bitbucket.org/pypa/setuptools/issue/114>`_: Use ``sys.getfilesystemencoding`` for decoding config in
+  ``bdist_wininst`` distributions.
+
+* `Issue #105 <https://bitbucket.org/pypa/setuptools/issue/105>`_ and `Issue #113 <https://bitbucket.org/pypa/setuptools/issue/113>`_: Establish a more robust technique for
+  determining the terminal encoding::
+
+    1. Try ``getpreferredencoding``
+    2. If that returns US_ASCII or None, try the encoding from
+       ``getdefaultlocale``. If that encoding was a "fallback" because Python
+       could not figure it out from the environment or OS, encoding remains
+       unresolved.
+    3. If the encoding is resolved, then make sure Python actually implements
+       the encoding.
+    4. On the event of an error or unknown codec, revert to fallbacks
+       (UTF-8 on Darwin, ASCII on everything else).
+    5. On the encoding is 'mac-roman' on Darwin, use UTF-8 as 'mac-roman' was
+       a bug on older Python releases.
+
+    On a side note, it would seem that the encoding only matters for when SVN
+    does not yet support ``--xml`` and when getting repository and svn version
+    numbers. The ``--xml`` technique should yield UTF-8 according to some
+    messages on the SVN mailing lists. So if the version numbers are always
+    7-bit ASCII clean, it may be best to only support the file parsing methods
+    for legacy SVN releases and support for SVN without the subprocess command
+    would simple go away as support for the older SVNs does.

+
+* `Issue #27 <https://bitbucket.org/pypa/setuptools/issue/27>`_: ``easy_install`` will now use credentials from .pypirc if
+  present for connecting to the package index.
+* `Pull Request #21 <https://bitbucket.org/pypa/setuptools/pull-request/21>`_: Omit unwanted newlines in ``package_index._encode_auth``

+
+---
+1.2
+---
+
+* `Issue #26 <https://bitbucket.org/pypa/setuptools/issue/26>`_: Add support for SVN 1.7. Special thanks to Philip Thiem for the
+  contribution.
+* `Issue #93 <https://bitbucket.org/pypa/setuptools/issue/93>`_: Wheels are now distributed with every release. Note that as
+  reported in `Issue #108 <https://bitbucket.org/pypa/setuptools/issue/108>`_, as of Pip 1.4, scripts aren't installed properly
+  from wheels. Therefore, if using Pip to install setuptools from a wheel,
+  the ``easy_install`` command will not be available.
+* Setuptools "natural" launcher support, introduced in 1.0, is now officially
+  supported.
+
+-----
+1.1.7
+-----
+
+* Fixed behavior of NameError handling in 'script template (dev).py' (script
+  launcher for 'develop' installs).
+* ``ez_setup.py`` now ensures partial downloads are cleaned up following
+  a failed download.
+* `Distribute #363 <https://bitbucket.org/tarek/distribute/issue/363>`_ and `Issue #55 <https://bitbucket.org/pypa/setuptools/issue/55>`_: Skip an sdist test that fails on locales
+  other than UTF-8.
+
+-----
+1.1.6
+-----
+
+* `Distribute #349 <https://bitbucket.org/tarek/distribute/issue/349>`_: ``sandbox.execfile`` now opens the target file in binary
+  mode, thus honoring a BOM in the file when compiled.
+
+-----
+1.1.5
+-----
+
+* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Second attempt at fix (logic was reversed).
+
+-----
+1.1.4
+-----
+
+* `Issue #77 <https://bitbucket.org/pypa/setuptools/issue/77>`_: Fix error in upload command (Python 2.4).
+
+-----
+1.1.3
+-----
+
+* Fix NameError in previous patch.
+
+-----
+1.1.2
+-----
+
+* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Correct issue where 404 errors are returned for URLs with
+  fragments in them (such as #egg=).
+
+-----
+1.1.1
+-----
+
+* `Issue #75 <https://bitbucket.org/pypa/setuptools/issue/75>`_: Add ``--insecure`` option to ez_setup.py to accommodate
+  environments where a trusted SSL connection cannot be validated.
+* `Issue #76 <https://bitbucket.org/pypa/setuptools/issue/76>`_: Fix AttributeError in upload command with Python 2.4.
+
+---
+1.1
+---
+
+* `Issue #71 <https://bitbucket.org/pypa/setuptools/issue/71>`_ (`Distribute #333 <https://bitbucket.org/tarek/distribute/issue/333>`_): EasyInstall now puts less emphasis on the
+  condition when a host is blocked via ``--allow-hosts``.
+* `Issue #72 <https://bitbucket.org/pypa/setuptools/issue/72>`_: Restored Python 2.4 compatibility in ``ez_setup.py``.
+
+---
+1.0
+---
+
+* `Issue #60 <https://bitbucket.org/pypa/setuptools/issue/60>`_: On Windows, Setuptools supports deferring to another launcher,
+  such as Vinay Sajip's `pylauncher <https://bitbucket.org/pypa/pylauncher>`_
+  (included with Python 3.3) to launch console and GUI scripts and not install
+  its own launcher executables. This experimental functionality is currently
+  only enabled if  the ``SETUPTOOLS_LAUNCHER`` environment variable is set to
+  "natural". In the future, this behavior may become default, but only after
+  it has matured and seen substantial adoption. The ``SETUPTOOLS_LAUNCHER``
+  also accepts "executable" to force the default behavior of creating launcher
+  executables.
+* `Issue #63 <https://bitbucket.org/pypa/setuptools/issue/63>`_: Bootstrap script (ez_setup.py) now prefers Powershell, curl, or
+  wget for retrieving the Setuptools tarball for improved security of the
+  install. The script will still fall back to a simple ``urlopen`` on
+  platforms that do not have these tools.
+* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Deprecated the ``Features`` functionality.
+* `Issue #52 <https://bitbucket.org/pypa/setuptools/issue/52>`_: In ``VerifyingHTTPSConn``, handle a tunnelled (proxied)
+  connection.
+
+Backward-Incompatible Changes
+=============================
+
+This release includes a couple of backward-incompatible changes, but most if
+not all users will find 1.0 a drop-in replacement for 0.9.
+
+* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: Normalized API of environment marker support. Specifically,
+  removed line number and filename from SyntaxErrors when returned from
+  `pkg_resources.invalid_marker`. Any clients depending on the specific
+  string representation of exceptions returned by that function may need to
+  be updated to account for this change.
+* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: SyntaxErrors generated by `pkg_resources.invalid_marker` are
+  normalized for cross-implementation consistency.
+* Removed ``--ignore-conflicts-at-my-risk`` and ``--delete-conflicting``
+  options to easy_install. These options have been deprecated since 0.6a11.
+
+-----
+0.9.8
+-----
+
+* `Issue #53 <https://bitbucket.org/pypa/setuptools/issue/53>`_: Fix NameErrors in `_vcs_split_rev_from_url`.

+* `Issue #34 <https://bitbucket.org/pypa/setuptools/issue/34>`_: Documentation now refers to bootstrap script in code repository
+  referenced by bookmark.
+* Add underscore-separated keys to environment markers (markerlib).
+
+-----
+0.9.6
+-----
+
+* `Issue #44 <https://bitbucket.org/pypa/setuptools/issue/44>`_: Test failure on Python 2.4 when MD5 hash doesn't have a `.name`

+-----
+
+* `Issue #42 <https://bitbucket.org/pypa/setuptools/issue/42>`_: Fix regression where blank checksums would trigger an
+  ``AttributeError``.
+
+-----
+0.9.1
+-----
+
+* `Distribute #386 <https://bitbucket.org/tarek/distribute/issue/386>`_: Allow other positional and keyword arguments to os.open.
+* Corrected dependency on certifi mis-referenced in 0.9.
+
+---
+0.9
+---
+
+* `package_index` now validates hashes other than MD5 in download links.
+
+---
+0.8
+---
+
+* Code base now runs on Python 2.4 - Python 3.3 without Python 2to3
+  conversion.
+
+-----
+0.7.8
+-----
+
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Yet another fix for yet another regression.
+
+-----
+0.7.7
+-----
+
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Repair AttributeError created in last release (redo).

+* Now honor the environment variable
+  ``SETUPTOOLS_DISABLE_VERSIONED_EASY_INSTALL_SCRIPT`` in addition to the now
+  deprecated ``DISTRIBUTE_DISABLE_VERSIONED_EASY_INSTALL_SCRIPT``.
+
+-----
+0.7.4
+-----
+
+* `Issue #20 <https://bitbucket.org/pypa/setuptools/issue/20>`_: Fix comparison of parsed SVN version on Python 3.
+
+-----
+0.7.3
+-----
+
+* `Issue #1 <https://bitbucket.org/pypa/setuptools/issue/1>`_: Disable installation of Windows-specific files on non-Windows systems.

+* `Issue #14 <https://bitbucket.org/pypa/setuptools/issue/14>`_: Use markerlib when the `parser` module is not available.
+* `Issue #10 <https://bitbucket.org/pypa/setuptools/issue/10>`_: ``ez_setup.py`` now uses HTTPS to download setuptools from PyPI.
+
+-----
+0.7.1

+* Fix NameError (`Issue #3 <https://bitbucket.org/pypa/setuptools/issue/3>`_) again - broken in bad merge.
+
+---
+0.7
+---
+
+* Merged Setuptools and Distribute. See docs/merge.txt for details.
+
+Added several features that were slated for setuptools 0.6c12:
+
+* Index URL now defaults to HTTPS.
+* Added experimental environment marker support. Now clients may designate a
+  PEP-426 environment marker for "extra" dependencies. Setuptools uses this
+  feature in ``setup.py`` for optional SSL and certificate validation support
+  on older platforms. Based on Distutils-SIG discussions, the syntax is
+  somewhat tentative. There should probably be a PEP with a firmer spec before
+  the feature should be considered suitable for use.
+* Added support for SSL certificate validation when installing packages from
+  an HTTPS service.
+
+-----
+0.7b4
+-----
+
+* `Issue #3 <https://bitbucket.org/pypa/setuptools/issue/3>`_: Fixed NameError in SSL support.
+
+------
+0.6.49
+------
+
+* Move warning check in ``get_cache_path`` to follow the directory creation
+  to avoid errors when the cache path does not yet exist. Fixes the error
+  reported in `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_.
+
+------
+0.6.48
+------
+
+* Correct AttributeError in ``ResourceManager.get_cache_path`` introduced in
+  0.6.46 (redo).
+
+------
+0.6.47
+------
+
+* Correct AttributeError in ``ResourceManager.get_cache_path`` introduced in
+  0.6.46.
+
+------
+0.6.46
+------
+
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Issue a warning if the PYTHON_EGG_CACHE or otherwise
+  customized egg cache location specifies a directory that's group- or
+  world-writable.
+
+------
+0.6.45
+------
+
+* `Distribute #379 <https://bitbucket.org/tarek/distribute/issue/379>`_: ``distribute_setup.py`` now traps VersionConflict as well,
+  restoring ability to upgrade from an older setuptools version.
+
+------
+0.6.44
+------
+
+* ``distribute_setup.py`` has been updated to allow Setuptools 0.7 to
+  satisfy use_setuptools.
+
+------
+0.6.43
+------
+
+* `Distribute #378 <https://bitbucket.org/tarek/distribute/issue/378>`_: Restore support for Python 2.4 Syntax (regression in 0.6.42).
+
+------
+0.6.42
+------
+
+* External links finder no longer yields duplicate links.
+* `Distribute #337 <https://bitbucket.org/tarek/distribute/issue/337>`_: Moved site.py to setuptools/site-patch.py (graft of very old
+  patch from setuptools trunk which inspired PR `#31 <https://bitbucket.org/pypa/setuptools/issue/31>`_).
+
+------
+0.6.41
+------
+
+* `Distribute #27 <https://bitbucket.org/tarek/distribute/issue/27>`_: Use public api for loading resources from zip files rather than
+  the private method `_zip_directory_cache`.
+* Added a new function ``easy_install.get_win_launcher`` which may be used by
+  third-party libraries such as buildout to get a suitable script launcher.
+
+------
+0.6.40
+------
+
+* `Distribute #376 <https://bitbucket.org/tarek/distribute/issue/376>`_: brought back cli.exe and gui.exe that were deleted in the
+  previous release.
+
+------
+0.6.39
+------
+
+* Add support for console launchers on ARM platforms.
+* Fix possible issue in GUI launchers where the subsystem was not supplied to
+  the linker.
+* Launcher build script now refactored for robustness.
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Resources extracted from a zip egg to the file system now also
+  check the contents of the file against the zip contents during each
+  invocation of get_resource_filename.
+
+------
+0.6.38
+------
+
+* `Distribute #371 <https://bitbucket.org/tarek/distribute/issue/371>`_: The launcher manifest file is now installed properly.
+
+------
+0.6.37
+------
+
+* `Distribute #143 <https://bitbucket.org/tarek/distribute/issue/143>`_: Launcher scripts, including easy_install itself, are now
+  accompanied by a manifest on 32-bit Windows environments to avoid the
+  Installer Detection Technology and thus undesirable UAC elevation described
+  in `this Microsoft article
+  <http://technet.microsoft.com/en-us/library/cc709628%28WS.10%29.aspx>`_.
+
+------
+0.6.36
+------
+
+* `Pull Request #35 <https://bitbucket.org/pypa/setuptools/pull-request/35>`_: In `Buildout #64 <https://github.com/buildout/buildout/issues/64>`_, it was reported that
+  under Python 3, installation of distutils scripts could attempt to copy
+  the ``__pycache__`` directory as a file, causing an error, apparently only
+  under Windows. Easy_install now skips all directories when processing
+  metadata scripts.
+
+------
+0.6.35
+------
+
+
+Note this release is backward-incompatible with distribute 0.6.23-0.6.34 in
+how it parses version numbers.
+
+* `Distribute #278 <https://bitbucket.org/tarek/distribute/issue/278>`_: Restored compatibility with distribute 0.6.22 and setuptools
+  0.6. Updated the documentation to match more closely with the version
+  parsing as intended in setuptools 0.6.
+
+------
+0.6.34
+------
+
+* `Distribute #341 <https://bitbucket.org/tarek/distribute/issue/341>`_: 0.6.33 fails to build under Python 2.4.

+* Fix 1 failure with Jython 2.5 and 2.7.
+* Disable workaround for Jython scripts on Linux systems.
+* `Distribute #336 <https://bitbucket.org/tarek/distribute/issue/336>`_: `setup.py` no longer masks failure exit code when tests fail.
+* Fix issue in pkg_resources where try/except around a platform-dependent
+  import would trigger hook load failures on Mercurial. See pull request 32
+  for details.
+* `Distribute #341 <https://bitbucket.org/tarek/distribute/issue/341>`_: Fix a ResourceWarning.
+
+------

+  until regression can be addressed.
+
+------
+0.6.31
+------
+
+* `Distribute #303 <https://bitbucket.org/tarek/distribute/issue/303>`_: Make sure the manifest only ever contains UTF-8 in Python 3.

+  Jython.
+* Work around `Jython #1980 <http://bugs.jython.org/issue1980>`_ and `Jython #1981 <http://bugs.jython.org/issue1981>`_.
+* `Distribute #334 <https://bitbucket.org/tarek/distribute/issue/334>`_: Provide workaround for packages that reference `sys.__stdout__`
+  such as numpy does. This change should address
+  `virtualenv `#359 <https://bitbucket.org/pypa/setuptools/issue/359>`_ <https://github.com/pypa/virtualenv/issues/359>`_ as long
+  as the system encoding is UTF-8 or the IO encoding is specified in the
+  environment, i.e.::
+
+     PYTHONIOENCODING=utf8 pip install numpy
+
+* Fix for encoding issue when installing from Windows executable on Python 3.
+* `Distribute #323 <https://bitbucket.org/tarek/distribute/issue/323>`_: Allow `setup_requires` requirements to supercede installed
+  requirements. Added some new keyword arguments to existing pkg_resources
+  methods. Also had to updated how __path__ is handled for namespace packages
+  to ensure that when a new egg distribution containing a namespace package is
+  placed on sys.path, the entries in __path__ are found in the same order they
+  would have been in had that egg been on the path when pkg_resources was
+  first imported.
+
+------
+0.6.30
+------
+
+* `Distribute #328 <https://bitbucket.org/tarek/distribute/issue/328>`_: Clean up temporary directories in distribute_setup.py.
+* Fix fatal bug in distribute_setup.py.
+
+------
+0.6.29
+------
+
+* `Pull Request #14 <https://bitbucket.org/pypa/setuptools/pull-request/14>`_: Honor file permissions in zip files.
+* `Distribute #327 <https://bitbucket.org/tarek/distribute/issue/327>`_: Merged pull request `#24 <https://bitbucket.org/pypa/setuptools/issue/24>`_ to fix a dependency problem with pip.
+* Merged pull request `#23 <https://bitbucket.org/pypa/setuptools/issue/23>`_ to fix https://github.com/pypa/virtualenv/issues/301.
+* If Sphinx is installed, the `upload_docs` command now runs `build_sphinx`
+  to produce uploadable documentation.
+* `Distribute #326 <https://bitbucket.org/tarek/distribute/issue/326>`_: `upload_docs` provided mangled auth credentials under Python 3.
+* `Distribute #320 <https://bitbucket.org/tarek/distribute/issue/320>`_: Fix check for "createable" in distribute_setup.py.
+* `Distribute #305 <https://bitbucket.org/tarek/distribute/issue/305>`_: Remove a warning that was triggered during normal operations.
+* `Distribute #311 <https://bitbucket.org/tarek/distribute/issue/311>`_: Print metadata in UTF-8 independent of platform.
+* `Distribute #303 <https://bitbucket.org/tarek/distribute/issue/303>`_: Read manifest file with UTF-8 encoding under Python 3.
+* `Distribute #301 <https://bitbucket.org/tarek/distribute/issue/301>`_: Allow to run tests of namespace packages when using 2to3.

+* `Distribute #283 <https://bitbucket.org/tarek/distribute/issue/283>`_: Reenable scanning of `*.pyc` / `*.pyo` files on Python 3.3.
+* `Distribute #299 <https://bitbucket.org/tarek/distribute/issue/299>`_: The develop command didn't work on Python 3, when using 2to3,
+  as the egg link would go to the Python 2 source. Linking to the 2to3'd code
+  in build/lib makes it work, although you will have to rebuild the module
+  before testing it.
+* `Distribute #306 <https://bitbucket.org/tarek/distribute/issue/306>`_: Even if 2to3 is used, we build in-place under Python 2.
+* `Distribute #307 <https://bitbucket.org/tarek/distribute/issue/307>`_: Prints the full path when .svn/entries is broken.
+* `Distribute #313 <https://bitbucket.org/tarek/distribute/issue/313>`_: Support for sdist subcommands (Python 2.7)
+* `Distribute #314 <https://bitbucket.org/tarek/distribute/issue/314>`_: test_local_index() would fail an OS X.
+* `Distribute #310 <https://bitbucket.org/tarek/distribute/issue/310>`_: Non-ascii characters in a namespace __init__.py causes errors.
+* `Distribute #218 <https://bitbucket.org/tarek/distribute/issue/218>`_: Improved documentation on behavior of `package_data` and
+  `include_package_data`. Files indicated by `package_data` are now included
+  in the manifest.

+0.6.27
+------
+
+* Support current snapshots of CPython 3.3.
+* Distribute now recognizes README.rst as a standard, default readme file.
+* Exclude 'encodings' modules when removing modules from sys.modules.

+  (bootstrap.py)
+
+------
+0.6.26

+* `Distribute #227 <https://bitbucket.org/tarek/distribute/issue/227>`_: Easy_install fetch parameters are now passed during the
+  installation of a source distribution; now fulfillment of setup_requires
+  dependencies will honor the parameters passed to easy_install.
+
+------
+0.6.25
+------
+
+* `Distribute #258 <https://bitbucket.org/tarek/distribute/issue/258>`_: Workaround a cache issue
+* `Distribute #260 <https://bitbucket.org/tarek/distribute/issue/260>`_: distribute_setup.py now accepts the --user parameter for
+  Python 2.6 and later.
+* `Distribute #262 <https://bitbucket.org/tarek/distribute/issue/262>`_: package_index.open_with_auth no longer throws LookupError
+  on Python 3.
+* `Distribute #269 <https://bitbucket.org/tarek/distribute/issue/269>`_: AttributeError when an exception occurs reading Manifest.in
+  on late releases of Python.
+* `Distribute #272 <https://bitbucket.org/tarek/distribute/issue/272>`_: Prevent TypeError when namespace package names are unicode
+  and single-install-externally-managed is used. Also fixes PIP issue
+  449.
+* `Distribute #273 <https://bitbucket.org/tarek/distribute/issue/273>`_: Legacy script launchers now install with Python2/3 support.
+
+------
+0.6.24
+------
+
+* `Distribute #249 <https://bitbucket.org/tarek/distribute/issue/249>`_: Added options to exclude 2to3 fixers

+* Added the 'DONT_PATCH_SETUPTOOLS' environment variable, so virtualenv
+  can drive an installation that doesn't patch a global setuptools.
+* Reviewed unladen-swallow specific change from
+  http://code.google.com/p/unladen-swallow/source/detail?spec=svn875&r=719
+  and determined that it no longer applies. Distribute should work fine with
+  Unladen Swallow 2009Q3.

+  httplib.HTTPException instead of just InvalidURL and BadStatusLine.
+* Removed virtual-python.py from this distribution and updated documentation
+  to point to the actively maintained virtualenv instead.
+* `Distribute #64 <https://bitbucket.org/tarek/distribute/issue/64>`_: use_setuptools no longer rebuilds the distribute egg every
+  time it is run
+* use_setuptools now properly respects the requested version
+* use_setuptools will no longer try to import a distribute egg for the
+  wrong Python version
+* `Distribute #74 <https://bitbucket.org/tarek/distribute/issue/74>`_: no_fake should be True by default.
+* `Distribute #72 <https://bitbucket.org/tarek/distribute/issue/72>`_: avoid a bootstrapping issue with easy_install -U
+
+-----

+  (patch by Holger Krekel)
+
+-----
+0.6.5
+-----
+
+* `Distribute #65 <https://bitbucket.org/tarek/distribute/issue/65>`_: cli.exe and gui.exe are now generated at build time,
+  depending on the platform in use.
+
+* `Distribute #67 <https://bitbucket.org/tarek/distribute/issue/67>`_: Fixed doc typo (PEP 381/382)
+
+* Distribute no longer shadows setuptools if we require a 0.7-series
+  setuptools.  And an error is raised when installing a 0.7 setuptools with
+  distribute.
+
+* When run from within buildout, no attempt is made to modify an existing
+  setuptools egg, whether in a shared egg directory or a system setuptools.
+
+* Fixed a hole in sandboxing allowing builtin file to write outside of
+  the sandbox.
+
+-----
+0.6.4

+
+-----
+0.6c9
+-----
+
+ * Fixed a missing files problem when using Windows source distributions on
+   non-Windows platforms, due to distutils not handling manifest file line
+   endings correctly.
+
+ * Updated Pyrex support to work with Pyrex 0.9.6 and higher.
+
+ * Minor changes for Jython compatibility, including skipping tests that can't
+   work on Jython.
+
+ * Fixed not installing eggs in ``install_requires`` if they were also used for
+   ``setup_requires`` or ``tests_require``.
+
+ * Fixed not fetching eggs in ``install_requires`` when running tests.
+
+ * Allow ``ez_setup.use_setuptools()`` to upgrade existing setuptools
+   installations when called from a standalone ``setup.py``.
+
+ * Added a warning if a namespace package is declared, but its parent package
+   is not also declared as a namespace.
+
+ * Support Subversion 1.5
+
+ * Removed use of deprecated ``md5`` module if ``hashlib`` is available
+
+ * Fixed ``bdist_wininst upload`` trying to upload the ``.exe`` twice
+
+ * Fixed ``bdist_egg`` putting a ``native_libs.txt`` in the source package's
+   ``.egg-info``, when it should only be in the built egg's ``EGG-INFO``.
+
+ * Ensure that _full_name is set on all shared libs before extensions are
+   checked for shared lib usage.  (Fixes a bug in the experimental shared
+   library build support.)
+
+ * Fix to allow unpacked eggs containing native libraries to fail more
+   gracefully under Google App Engine (with an ``ImportError`` loading the
+   C-based module, instead of getting a ``NameError``).
+
+-----
+0.6c7
+-----
+
+ * Fixed ``distutils.filelist.findall()`` crashing on broken symlinks, and
+   ``egg_info`` command failing on new, uncommitted SVN directories.
+
+ * Fix import problems with nested namespace packages installed via
+   ``--root`` or ``--single-version-externally-managed``, due to the
+   parent package not having the child package as an attribute.
+
+-----
+0.6c6
+-----
+
+ * Added ``--egg-path`` option to ``develop`` command, allowing you to force
+   ``.egg-link`` files to use relative paths (allowing them to be shared across
+   platforms on a networked drive).
+
+ * Fix not building binary RPMs correctly.
+
+ * Fix "eggsecutables" (such as setuptools' own egg) only being runnable with
+   bash-compatible shells.
+
+ * Fix ``#!`` parsing problems in Windows ``.exe`` script wrappers, when there
+   was whitespace inside a quoted argument or at the end of the ``#!`` line
+   (a regression introduced in 0.6c4).
+
+ * Fix ``test`` command possibly failing if an older version of the project
+   being tested was installed on ``sys.path`` ahead of the test source
+   directory.
+
+ * Fix ``find_packages()`` treating ``ez_setup`` and directories with ``.`` in
+   their names as packages.
+
+-----
+0.6c5
+-----
+
+ * Fix uploaded ``bdist_rpm`` packages being described as ``bdist_egg``
+   packages under Python versions less than 2.5.
+
+ * Fix uploaded ``bdist_wininst`` packages being described as suitable for
+   "any" version by Python 2.5, even if a ``--target-version`` was specified.
+
+-----
+0.6c4
+-----
+
+ * Overhauled Windows script wrapping to support ``bdist_wininst`` better.
+   Scripts installed with ``bdist_wininst`` will always use ``#!python.exe`` or
+   ``#!pythonw.exe`` as the executable name (even when built on non-Windows
+   platforms!), and the wrappers will look for the executable in the script's
+   parent directory (which should find the right version of Python).
+
+ * Fix ``upload`` command not uploading files built by ``bdist_rpm`` or
+   ``bdist_wininst`` under Python 2.3 and 2.4.
+
+ * Add support for "eggsecutable" headers: a ``#!/bin/sh`` script that is
+   prepended to an ``.egg`` file to allow it to be run as a script on Unix-ish
+   platforms.  (This is mainly so that setuptools itself can have a single-file
+   installer on Unix, without doing multiple downloads, dealing with firewalls,
+   etc.)
+
+ * Fix problem with empty revision numbers in Subversion 1.4 ``entries`` files
+
+ * Use cross-platform relative paths in ``easy-install.pth`` when doing
+   ``develop`` and the source directory is a subdirectory of the installation
+   target directory.
+
+ * Fix a problem installing eggs with a system packaging tool if the project
+   contained an implicit namespace package; for example if the ``setup()``
+   listed a namespace package ``foo.bar`` without explicitly listing ``foo``
+   as a namespace package.
+
+-----
+0.6c3
+-----
+
+ * Fixed breakages caused by Subversion 1.4's new "working copy" format
+
+-----
+0.6c2
+-----
+
+ * The ``ez_setup`` module displays the conflicting version of setuptools (and
+   its installation location) when a script requests a version that's not
+   available.
+
+ * Running ``setup.py develop`` on a setuptools-using project will now install
+   setuptools if needed, instead of only downloading the egg.
+
+-----
+0.6c1
+-----
+
+ * Fixed ``AttributeError`` when trying to download a ``setup_requires``
+   dependency when a distribution lacks a ``dependency_links`` setting.
+
+ * Made ``zip-safe`` and ``not-zip-safe`` flag files contain a single byte, so
+   as to play better with packaging tools that complain about zero-length
+   files.
+
+ * Made ``setup.py develop`` respect the ``--no-deps`` option, which it
+   previously was ignoring.
+
+ * Support ``extra_path`` option to ``setup()`` when ``install`` is run in
+   backward-compatibility mode.
+
+ * Source distributions now always include a ``setup.cfg`` file that explicitly
+   sets ``egg_info`` options such that they produce an identical version number
+   to the source distribution's version number.  (Previously, the default
+   version number could be different due to the use of ``--tag-date``, or if
+   the version was overridden on the command line that built the source
+   distribution.)
+
+-----
+0.6b4
+-----
+
+ * Fix ``register`` not obeying name/version set by ``egg_info`` command, if
+   ``egg_info`` wasn't explicitly run first on the same command line.
+
+ * Added ``--no-date`` and ``--no-svn-revision`` options to ``egg_info``
+   command, to allow suppressing tags configured in ``setup.cfg``.
+
+ * Fixed redundant warnings about missing ``README`` file(s); it should now
+   appear only if you are actually a source distribution.
+
+-----
+0.6b3
+-----
+
+ * Fix ``bdist_egg`` not including files in subdirectories of ``.egg-info``.
+
+ * Allow ``.py`` files found by the ``include_package_data`` option to be
+   automatically included.  Remove duplicate data file matches if both
+   ``include_package_data`` and ``package_data`` are used to refer to the same
+   files.
+
+-----
+0.6b1
+-----
+
+ * Strip ``module`` from the end of compiled extension modules when computing
+   the name of a ``.py`` loader/wrapper.  (Python's import machinery ignores
+   this suffix when searching for an extension module.)
+
+------
+0.6a11
+------
+
+ * Added ``test_loader`` keyword to support custom test loaders
+
+ * Added ``setuptools.file_finders`` entry point group to allow implementing
+   revision control plugins.
+
+ * Added ``--identity`` option to ``upload`` command.
+
+ * Added ``dependency_links`` to allow specifying URLs for ``--find-links``.
+
+ * Enhanced test loader to scan packages as well as modules, and call
+   ``additional_tests()`` if present to get non-unittest tests.
+
+ * Support namespace packages in conjunction with system packagers, by omitting
+   the installation of any ``__init__.py`` files for namespace packages, and
+   adding a special ``.pth`` file to create a working package in
+   ``sys.modules``.
+
+ * Made ``--single-version-externally-managed`` automatic when ``--root`` is
+   used, so that most system packagers won't require special support for
+   setuptools.
+
+ * Fixed ``setup_requires``, ``tests_require``, etc. not using ``setup.cfg`` or
+   other configuration files for their option defaults when installing, and
+   also made the install use ``--multi-version`` mode so that the project
+   directory doesn't need to support .pth files.
+
+ * ``MANIFEST.in`` is now forcibly closed when any errors occur while reading
+   it.  Previously, the file could be left open and the actual error would be
+   masked by problems trying to remove the open file on Windows systems.
+
+------
+0.6a10
+------
+
+ * Fixed the ``develop`` command ignoring ``--find-links``.
+
+-----
+0.6a9
+-----
+
+ * The ``sdist`` command no longer uses the traditional ``MANIFEST`` file to
+   create source distributions.  ``MANIFEST.in`` is still read and processed,
+   as are the standard defaults and pruning.  But the manifest is built inside
+   the project's ``.egg-info`` directory as ``SOURCES.txt``, and it is rebuilt
+   every time the ``egg_info`` command is run.
+
+ * Added the ``include_package_data`` keyword to ``setup()``, allowing you to
+   automatically include any package data listed in revision control or
+   ``MANIFEST.in``
+
+ * Added the ``exclude_package_data`` keyword to ``setup()``, allowing you to
+   trim back files included via the ``package_data`` and
+   ``include_package_data`` options.
+
+ * Fixed ``--tag-svn-revision`` not working when run from a source
+   distribution.
+
+ * Added warning for namespace packages with missing ``declare_namespace()``
+
+ * Added ``tests_require`` keyword to ``setup()``, so that e.g. packages
+   requiring ``nose`` to run unit tests can make this dependency optional
+   unless the ``test`` command is run.
+
+ * Made all commands that use ``easy_install`` respect its configuration
+   options, as this was causing some problems with ``setup.py install``.
+
+ * Added an ``unpack_directory()`` driver to ``setuptools.archive_util``, so
+   that you can process a directory tree through a processing filter as if it
+   were a zipfile or tarfile.
+
+ * Added an internal ``install_egg_info`` command to use as part of old-style
+   ``install`` operations, that installs an ``.egg-info`` directory with the
+   package.
+
+ * Added a ``--single-version-externally-managed`` option to the ``install``
+   command so that you can more easily wrap a "flat" egg in a system package.
+
+ * Enhanced ``bdist_rpm`` so that it installs single-version eggs that
+   don't rely on a ``.pth`` file.  The ``--no-egg`` option has been removed,
+   since all RPMs are now built in a more backwards-compatible format.
+
+ * Support full roundtrip translation of eggs to and from ``bdist_wininst``
+   format.  Running ``bdist_wininst`` on a setuptools-based package wraps the
+   egg in an .exe that will safely install it as an egg (i.e., with metadata
+   and entry-point wrapper scripts), and ``easy_install`` can turn the .exe
+   back into an ``.egg`` file or directory and install it as such.
+
+
+-----
+0.6a8
+-----
+
+ * Fixed some problems building extensions when Pyrex was installed, especially
+   with Python 2.4 and/or packages using SWIG.
+
+ * Made ``develop`` command accept all the same options as ``easy_install``,
+   and use the ``easy_install`` command's configuration settings as defaults.
+
+ * Made ``egg_info --tag-svn-revision`` fall back to extracting the revision
+   number from ``PKG-INFO`` in case it is being run on a source distribution of
+   a snapshot taken from a Subversion-based project.
+
+ * Automatically detect ``.dll``, ``.so`` and ``.dylib`` files that are being
+   installed as data, adding them to ``native_libs.txt`` automatically.
+
+ * Fixed some problems with fresh checkouts of projects that don't include
+   ``.egg-info/PKG-INFO`` under revision control and put the project's source
+   code directly in the project directory.  If such a package had any
+   requirements that get processed before the ``egg_info`` command can be run,
+   the setup scripts would fail with a "Missing 'Version:' header and/or
+   PKG-INFO file" error, because the egg runtime interpreted the unbuilt
+   metadata in a directory on ``sys.path`` (i.e. the current directory) as
+   being a corrupted egg.  Setuptools now monkeypatches the distribution
+   metadata cache to pretend that the egg has valid version information, until
+   it has a chance to make it actually be so (via the ``egg_info`` command).
+
+-----
+0.6a5
+-----
+
+ * Fixed missing gui/cli .exe files in distribution.  Fixed bugs in tests.
+
+-----
+0.6a3
+-----
+
+ * Added ``gui_scripts`` entry point group to allow installing GUI scripts
+   on Windows and other platforms.  (The special handling is only for Windows;
+   other platforms are treated the same as for ``console_scripts``.)
+
+-----
+0.6a2
+-----
+
+ * Added ``console_scripts`` entry point group to allow installing scripts
+   without the need to create separate script files.  On Windows, console
+   scripts get an ``.exe`` wrapper so you can just type their name.  On other
+   platforms, the scripts are written without a file extension.
+
+-----
+0.6a1
+-----
+
+ * Added support for building "old-style" RPMs that don't install an egg for
+   the target package, using a ``--no-egg`` option.
+
+ * The ``build_ext`` command now works better when using the ``--inplace``
+   option and multiple Python versions.  It now makes sure that all extensions
+   match the current Python version, even if newer copies were built for a
+   different Python version.
+
+ * The ``upload`` command no longer attaches an extra ``.zip`` when uploading
+   eggs, as PyPI now supports egg uploads without trickery.
+
+ * The ``ez_setup`` script/module now displays a warning before downloading
+   the setuptools egg, and attempts to check the downloaded egg against an
+   internal MD5 checksum table.
+
+ * Fixed the ``--tag-svn-revision`` option of ``egg_info`` not finding the
+   latest revision number; it was using the revision number of the directory
+   containing ``setup.py``, not the highest revision number in the project.
+
+ * Added ``eager_resources`` setup argument
+
+ * The ``sdist`` command now recognizes Subversion "deleted file" entries and
+   does not include them in source distributions.
+
+ * ``setuptools`` now embeds itself more thoroughly into the distutils, so that
+   other distutils extensions (e.g. py2exe, py2app) will subclass setuptools'
+   versions of things, rather than the native distutils ones.
+
+ * Added ``entry_points`` and ``setup_requires`` arguments to ``setup()``;
+   ``setup_requires`` allows you to automatically find and download packages
+   that are needed in order to *build* your project (as opposed to running it).
+
+ * ``setuptools`` now finds its commands, ``setup()`` argument validators, and
+   metadata writers using entry points, so that they can be extended by
+   third-party packages.  See `Creating distutils Extensions
+   <http://pythonhosted.org/setuptools/setuptools.html#creating-distutils-extensions>`_
+   for more details.
+
+ * The vestigial ``depends`` command has been removed.  It was never finished
+   or documented, and never would have worked without EasyInstall - which it
+   pre-dated and was never compatible with.
+
+------
+0.5a12
+------
+
+ * The zip-safety scanner now checks for modules that might be used with
+   ``python -m``, and marks them as unsafe for zipping, since Python 2.4 can't
+   handle ``-m`` on zipped modules.
+
+------
+0.5a11
+------
+
+ * Fix breakage of the "develop" command that was caused by the addition of
+   ``--always-unzip`` to the ``easy_install`` command.
+
+-----
+0.5a9
+-----
+
+ * Include ``svn:externals`` directories in source distributions as well as
+   normal subversion-controlled files and directories.
+
+ * Added ``exclude=patternlist`` option to ``setuptools.find_packages()``
+
+ * Changed --tag-svn-revision to include an "r" in front of the revision number
+   for better readability.
+
+ * Added ability to build eggs without including source files (except for any
+   scripts, of course), using the ``--exclude-source-files`` option to
+   ``bdist_egg``.
+
+ * ``setup.py install`` now automatically detects when an "unmanaged" package
+   or module is going to be on ``sys.path`` ahead of a package being installed,
+   thereby preventing the newer version from being imported.  If this occurs,
+   a warning message is output to ``sys.stderr``, but installation proceeds
+   anyway.  The warning message informs the user what files or directories
+   need deleting, and advises them they can also use EasyInstall (with the
+   ``--delete-conflicting`` option) to do it automatically.
+
+ * The ``egg_info`` command now adds a ``top_level.txt`` file to the metadata
+   directory that lists all top-level modules and packages in the distribution.
+   This is used by the ``easy_install`` command to find possibly-conflicting
+   "unmanaged" packages when installing the distribution.
+
+ * Added ``zip_safe`` and ``namespace_packages`` arguments to ``setup()``.
+   Added package analysis to determine zip-safety if the ``zip_safe`` flag
+   is not given, and advise the author regarding what code might need changing.
+
+ * Fixed the swapped ``-d`` and ``-b`` options of ``bdist_egg``.
+
+-----
+0.5a8
+-----
+
+ * The "egg_info" command now always sets the distribution metadata to "safe"
+   forms of the distribution name and version, so that distribution files will
+   be generated with parseable names (i.e., ones that don't include '-' in the
+   name or version).  Also, this means that if you use the various ``--tag``
+   options of "egg_info", any distributions generated will use the tags in the
+   version, not just egg distributions.
+
+ * Added support for defining command aliases in distutils configuration files,
+   under the "[aliases]" section.  To prevent recursion and to allow aliases to
+   call the command of the same name, a given alias can be expanded only once
+   per command-line invocation.  You can define new aliases with the "alias"
+   command, either for the local, global, or per-user configuration.
+
+ * Added "rotate" command to delete old distribution files, given a set of
+   patterns to match and the number of files to keep.  (Keeps the most
+   recently-modified distribution files matching each pattern.)
+
+ * Added "saveopts" command that saves all command-line options for the current
+   invocation to the local, global, or per-user configuration file.  Useful for
+   setting defaults without having to hand-edit a configuration file.
+
+ * Added a "setopt" command that sets a single option in a specified distutils
+   configuration file.
+
+-----
+0.5a7
+-----
+
+ * Added "upload" support for egg and source distributions, including a bug
+   fix for "upload" and a temporary workaround for lack of .egg support in
+   PyPI.
+
+-----
+0.5a6
+-----
+
+ * Beefed up the "sdist" command so that if you don't have a MANIFEST.in, it
+   will include all files under revision control (CVS or Subversion) in the
+   current directory, and it will regenerate the list every time you create a
+   source distribution, not just when you tell it to.  This should make the
+   default "do what you mean" more often than the distutils' default behavior
+   did, while still retaining the old behavior in the presence of MANIFEST.in.
+
+ * Fixed the "develop" command always updating .pth files, even if you
+   specified ``-n`` or ``--dry-run``.
+
+ * Slightly changed the format of the generated version when you use
+   ``--tag-build`` on the "egg_info" command, so that you can make tagged
+   revisions compare *lower* than the version specified in setup.py (e.g. by
+   using ``--tag-build=dev``).
+
+-----
+0.5a5
+-----
+
+ * Added ``develop`` command to ``setuptools``-based packages.  This command
+   installs an ``.egg-link`` pointing to the package's source directory, and
+   script wrappers that ``execfile()`` the source versions of the package's
+   scripts.  This lets you put your development checkout(s) on sys.path without
+   having to actually install them.  (To uninstall the link, use
+   use ``setup.py develop --uninstall``.)
+
+ * Added ``egg_info`` command to ``setuptools``-based packages.  This command
+   just creates or updates the "projectname.egg-info" directory, without
+   building an egg.  (It's used by the ``bdist_egg``, ``test``, and ``develop``
+   commands.)
+
+ * Enhanced the ``test`` command so that it doesn't install the package, but
+   instead builds any C extensions in-place, updates the ``.egg-info``
+   metadata, adds the source directory to ``sys.path``, and runs the tests
+   directly on the source.  This avoids an "unmanaged" installation of the
+   package to ``site-packages`` or elsewhere.
+
+ * Made ``easy_install`` a standard ``setuptools`` command, moving it from
+   the ``easy_install`` module to ``setuptools.command.easy_install``.  Note
+   that if you were importing or extending it, you must now change your imports
+   accordingly.  ``easy_install.py`` is still installed as a script, but not as
+   a module.
+
+-----
+0.5a4
+-----
+
+ * Setup scripts using setuptools can now list their dependencies directly in
+   the setup.py file, without having to manually create a ``depends.txt`` file.
+   The ``install_requires`` and ``extras_require`` arguments to ``setup()``
+   are used to create a dependencies file automatically.  If you are manually
+   creating ``depends.txt`` right now, please switch to using these setup
+   arguments as soon as practical, because ``depends.txt`` support will be
+   removed in the 0.6 release cycle.  For documentation on the new arguments,
+   see the ``setuptools.dist.Distribution`` class.
+
+ * Setup scripts using setuptools now always install using ``easy_install``
+   internally, for ease of uninstallation and upgrading.
+
+-----
+0.5a1
+-----
+
+ * Added support for "self-installation" bootstrapping.  Packages can now
+   include ``ez_setup.py`` in their source distribution, and add the following
+   to their ``setup.py``, in order to automatically bootstrap installation of
+   setuptools as part of their setup process::
+
+    from ez_setup import use_setuptools
+    use_setuptools()
+
+    from setuptools import setup
+    # etc...
+
+-----
+0.4a2
+-----
+
+ * Added ``ez_setup.py`` installer/bootstrap script to make initial setuptools
+   installation easier, and to allow distributions using setuptools to avoid
+   having to include setuptools in their source distribution.
+
+ * All downloads are now managed by the ``PackageIndex`` class (which is now
+   subclassable and replaceable), so that embedders can more easily override
+   download logic, give download progress reports, etc.  The class has also
+   been moved to the new ``setuptools.package_index`` module.
+
+ * The ``Installer`` class no longer handles downloading, manages a temporary
+   directory, or tracks the ``zip_ok`` option.  Downloading is now handled
+   by ``PackageIndex``, and ``Installer`` has become an ``easy_install``
+   command class based on ``setuptools.Command``.
+
+ * There is a new ``setuptools.sandbox.run_setup()`` API to invoke a setup
+   script in a directory sandbox, and a new ``setuptools.archive_util`` module
+   with an ``unpack_archive()`` API.  These were split out of EasyInstall to
+   allow reuse by other tools and applications.
+
+ * ``setuptools.Command`` now supports reinitializing commands using keyword
+   arguments to set/reset options.  Also, ``Command`` subclasses can now set
+   their ``command_consumes_arguments`` attribute to ``True`` in order to
+   receive an ``args`` option containing the rest of the command line.
+
+-----
+0.3a2
+-----
+
+ * Added new options to ``bdist_egg`` to allow tagging the egg's version number
+   with a subversion revision number, the current date, or an explicit tag
+   value.  Run ``setup.py bdist_egg --help`` to get more information.
+
+ * Misc. bug fixes
+
+-----
+0.3a1
+-----
+
+ * Initial release.

+===============================
+Installing and Using Setuptools
+===============================
+
+.. contents:: **Table of Contents**
+
+
+-------------------------
+Installation Instructions
+-------------------------
+
+The recommended way to bootstrap setuptools on any system is to download
+`ez_setup.py`_ and run it using the target Python environment. Different
+operating systems have different recommended techniques to accomplish this
+basic routine, so below are some examples to get you started.
+
+Setuptools requires Python 2.6 or later. To install setuptools
+on Python 2.4 or Python 2.5, use the `bootstrap script for Setuptools 1.x
+<https://bitbucket.org/pypa/setuptools/raw/bootstrap-py24/ez_setup.py>`_.
+
+The link provided to ez_setup.py is a bookmark to bootstrap script for the
+latest known stable release.
+
+.. _ez_setup.py: https://bootstrap.pypa.io/ez_setup.py
+
+Windows (Powershell 3 or later)
+===============================
+
+For best results, uninstall previous versions FIRST (see `Uninstalling`_).
+
+Using Windows 8 (which includes PowerShell 3) or earlier versions of Windows
+with PowerShell 3 installed, it's possible to install with one simple
+Powershell command. Start up Powershell and paste this command::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python -
+
+You must start the Powershell with Administrative privileges or you may choose
+to install a user-local installation::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python - --user
+
+If you have Python 3.3 or later, you can use the ``py`` command to install to
+different Python versions. For example, to install to Python 3.3 if you have
+Python 2.7 installed::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | py -3 -
+
+The recommended way to install setuptools on Windows is to download
+`ez_setup.py`_ and run it. The script will download the appropriate
+distribution file and install it for you.
+
+Once installation is complete, you will find an ``easy_install`` program in
+your Python ``Scripts`` subdirectory.  For simple invocation and best results,
+add this directory to your ``PATH`` environment variable, if it is not already
+present. If you did a user-local install, the ``Scripts`` subdirectory is
+``$env:APPDATA\Python\Scripts``.
+
+
+Windows (simplified)
+====================
+
+For Windows without PowerShell 3 or for installation without a command-line,
+download `ez_setup.py`_ using your preferred web browser or other technique
+and "run" that file.
+
+
+Unix (wget)
+===========
+
+Most Linux distributions come with wget.
+
+Download `ez_setup.py`_ and run it using the target Python version. The script
+will download the appropriate version and install it for you::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | python
+
+Note that you will may need to invoke the command with superuser privileges to
+install to the system Python::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
+
+Alternatively, Setuptools may be installed to a user-local path::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | python - --user
+
+Unix including Mac OS X (curl)
+==============================
+
+If your system has curl installed, follow the ``wget`` instructions but
+replace ``wget`` with ``curl`` and ``-O`` with ``-o``. For example::
+
+    > curl https://bootstrap.pypa.io/ez_setup.py -o - | python
+
+
+Advanced Installation
+=====================
+
+For more advanced installation options, such as installing to custom
+locations or prefixes, download and extract the source
+tarball from `Setuptools on PyPI <https://pypi.python.org/pypi/setuptools>`_
+and run setup.py with any supported distutils and Setuptools options.
+For example::
+
+    setuptools-x.x$ python setup.py install --prefix=/opt/setuptools
+
+Use ``--help`` to get a full options list, but we recommend consulting
+the `EasyInstall manual`_ for detailed instructions, especially `the section
+on custom installation locations`_.
+
+.. _EasyInstall manual: https://pythonhosted.org/setuptools/EasyInstall
+.. _the section on custom installation locations: https://pythonhosted.org/setuptools/EasyInstall#custom-installation-locations
+
+
+Downloads
+=========
+
+All setuptools downloads can be found at `the project's home page in the Python
+Package Index`_.  Scroll to the very bottom of the page to find the links.
+
+.. _the project's home page in the Python Package Index: https://pypi.python.org/pypi/setuptools
+
+In addition to the PyPI downloads, the development version of ``setuptools``
+is available from the `Bitbucket repo`_, and in-development versions of the
+`0.6 branch`_ are available as well.
+
+.. _Bitbucket repo: https://bitbucket.org/pypa/setuptools/get/default.tar.gz#egg=setuptools-dev
+.. _0.6 branch: http://svn.python.org/projects/sandbox/branches/setuptools-0.6/#egg=setuptools-dev06
+
+Uninstalling
+============
+
+On Windows, if Setuptools was installed using an ``.exe`` or ``.msi``
+installer, simply use the uninstall feature of "Add/Remove Programs" in the
+Control Panel.
+
+Otherwise, to uninstall Setuptools or Distribute, regardless of the Python
+version, delete all ``setuptools*`` and ``distribute*`` files and
+directories from your system's ``site-packages`` directory
+(and any other ``sys.path`` directories) FIRST.
+
+If you are upgrading or otherwise plan to re-install Setuptools or Distribute,
+nothing further needs to be done. If you want to completely remove Setuptools,
+you may also want to remove the 'easy_install' and 'easy_install-x.x' scripts
+and associated executables installed to the Python scripts directory.
+

+
+Here are some of the available manuals, tutorials, and other resources for
+learning about Setuptools, Python Eggs, and EasyInstall:

+* `The setuptools Developer's Guide`_
+* `The pkg_resources API reference`_
+* `Package Compatibility Notes`_ (user-maintained)
+* `The Internal Structure of Python Eggs`_
+
+Questions, comments, and bug reports should be directed to the `distutils-sig
+mailing list`_.  If you have written (or know of) any tutorials, documentation,
+plug-ins, or other resources for setuptools users, please let us know about
+them there, so this reference list can be updated.  If you have working,
+*tested* patches to correct problems or add features, you may submit them to
+the `setuptools bug tracker`_.

+
+* The original design for the ``.egg`` format and the ``pkg_resources`` API was
+  co-created by Phillip Eby and Bob Ippolito.  Bob also implemented the first
+  version of ``pkg_resources``, and supplied the OS X operating system version
+  compatibility algorithm.
+
+* Ian Bicking implemented many early "creature comfort" features of
+  easy_install, including support for downloading via Sourceforge and
+  Subversion repositories.  Ian's comments on the Web-SIG about WSGI
+  application deployment also inspired the concept of "entry points" in eggs,
+  and he has given talks at PyCon and elsewhere to inform and educate the
+  community about eggs and setuptools.
+
+* Jim Fulton contributed time and effort to build automated tests of various
+  aspects of ``easy_install``, and supplied the doctests for the command-line
+  ``.exe`` wrappers on Windows.
+
+* Phillip J. Eby is the seminal author of setuptools, and
+  first proposed the idea of an importable binary distribution format for
+  Python application plug-ins.
+
+* Significant parts of the implementation of setuptools were funded by the Open
+  Source Applications Foundation, to provide a plug-in infrastructure for the
+  Chandler PIM application.  In addition, many OSAF staffers (such as Mike
+  "Code Bear" Taylor) contributed their time and stress as guinea pigs for the
+  use of eggs and setuptools, even before eggs were "cool".  (Thanks, guys!)
+
+* Tarek Ziadé is the principal author of the Distribute fork, which
+  re-invigorated the community on the project, encouraged renewed innovation,
+  and addressed many defects.
+
+* Since the merge with Distribute, Jason R. Coombs is the
+  maintainer of setuptools.  The project is maintained in coordination with
+  the Python Packaging Authority (PyPA) and the larger Python community.

+
+-----
+6.0.2
+-----
+
+* `Issue #262 <https://bitbucket.org/pypa/setuptools/issue/262>`_: Fixed regression in pip install due to egg-info directories
+  being omitted. Re-opens `Issue #118 <https://bitbucket.org/pypa/setuptools/issue/118>`_.
+
+-----
+6.0.1
+-----
+
+* `Issue #259 <https://bitbucket.org/pypa/setuptools/issue/259>`_: Fixed regression with namespace package handling on ``single
+  version, externally managed`` installs.
+
+---
+6.0
+---
+
+* `Issue #100 <https://bitbucket.org/pypa/setuptools/issue/100>`_: When building a distribution, Setuptools will no longer match
+  default files using platform-dependent case sensitivity, but rather will
+  only match the files if their case matches exactly. As a result, on Windows
+  and other case-insensitive file systems, files with names such as
+  'readme.txt' or 'README.TXT' will be omitted from the distribution and a
+  warning will be issued indicating that 'README.txt' was not found. Other
+  filenames affected are:
+
+    - README.rst
+    - README
+    - setup.cfg
+    - setup.py (or the script name)
+    - test/test*.py
+
+  Any users producing distributions with filenames that match those above
+  case-insensitively, but not case-sensitively, should rename those files in
+  their repository for better portability.
+* `Pull Request #72 <https://bitbucket.org/pypa/setuptools/pull-request/72>`_: When using ``single_version_externally_managed``, the
+  exclusion list now includes Python 3.2 ``__pycache__`` entries.
+* `Pull Request #76 <https://bitbucket.org/pypa/setuptools/pull-request/76>`_ and `Pull Request #78 <https://bitbucket.org/pypa/setuptools/pull-request/78>`_: lines in top_level.txt are now
+  ordered deterministically.
+* `Issue #118 <https://bitbucket.org/pypa/setuptools/issue/118>`_: The egg-info directory is now no longer included in the list
+  of outputs.
+* `Issue #258 <https://bitbucket.org/pypa/setuptools/issue/258>`_: Setuptools now patches distutils msvc9compiler to
+  recognize the specially-packaged compiler package for easy extension module
+  support on Python 2.6, 2.7, and 3.2.
+
+---
+5.8
+---
+
+* `Issue #237 <https://bitbucket.org/pypa/setuptools/issue/237>`_: ``pkg_resources`` now uses explicit detection of Python 2 vs.
+  Python 3, supporting environments where builtins have been patched to make
+  Python 3 look more like Python 2.
+
+---
+5.7
+---
+
+* `Issue #240 <https://bitbucket.org/pypa/setuptools/issue/240>`_: Based on real-world performance measures against 5.4, zip
+  manifests are now cached in all circumstances. The
+  ``PKG_RESOURCES_CACHE_ZIP_MANIFESTS`` environment variable is no longer
+  relevant. The observed "memory increase" referenced in the 5.4 release
+  notes and detailed in `Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154>`_ was likely not an increase over the status
+  quo, but rather only an increase over not storing the zip info at all.
+
+---
+5.6
+---
+
+* `Issue #242 <https://bitbucket.org/pypa/setuptools/issue/242>`_: Use absolute imports in svn_utils to avoid issues if the
+  installing package adds an xml module to the path.
+
+-----
+5.5.1
+-----
+
+* `Issue #239 <https://bitbucket.org/pypa/setuptools/issue/239>`_: Fix typo in 5.5 such that fix did not take.
+
+---
+5.5
+---
+
+* `Issue #239 <https://bitbucket.org/pypa/setuptools/issue/239>`_: Setuptools now includes the setup_requires directive on
+  Distribution objects and validates the syntax just like install_requires
+  and tests_require directives.
+
+-----
+5.4.2
+-----
+
+* `Issue #236 <https://bitbucket.org/pypa/setuptools/issue/236>`_: Corrected regression in execfile implementation for Python 2.6.
+
+-----
+5.4.1
+-----
+
+* `Python #7776 <http://bugs.python.org/issue7776>`_: (ssl_support) Correct usage of host for validation when
+  tunneling for HTTPS.
+
+---
+5.4
+---
+
+* `Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154>`_: ``pkg_resources`` will now cache the zip manifests rather than
+  re-processing the same file from disk multiple times, but only if the
+  environment variable ``PKG_RESOURCES_CACHE_ZIP_MANIFESTS`` is set. Clients
+  that package many modules in the same zip file will see some improvement
+  in startup time by enabling this feature. This feature is not enabled by
+  default because it causes a substantial increase in memory usage.
+
+---
+5.3
+---
+
+* `Issue #185 <https://bitbucket.org/pypa/setuptools/issue/185>`_: Make svn tagging work on the new style SVN metadata.
+  Thanks cazabon!
+* Prune revision control directories (e.g .svn) from base path
+  as well as sub-directories.
+
+---
+5.2
+---
+
+* Added a `Developer Guide
+  <https://pythonhosted.org/setuptools/developer-guide.html>`_ to the official
+  documentation.
+* Some code refactoring and cleanup was done with no intended behavioral
+  changes.
+* During install_egg_info, the generated lines for namespace package .pth
+  files are now processed even during a dry run.
+
+---
+5.1
+---
+
+* `Issue #202 <https://bitbucket.org/pypa/setuptools/issue/202>`_: Implemented more robust cache invalidation for the ZipImporter,
+  building on the work in `Issue #168 <https://bitbucket.org/pypa/setuptools/issue/168>`_. Special thanks to Jurko Gospodnetic and
+  PJE.
+

+
+* `Issue #220 <https://bitbucket.org/pypa/setuptools/issue/220>`_: Restored script templates.
+
+-----
+5.0.1
+-----
+
+* Renamed script templates to end with .tmpl now that they no longer need

+
+---
+5.0
+---
+
+* `Issue #218 <https://bitbucket.org/pypa/setuptools/issue/218>`_: Re-release of 3.8.1 to signal that it supersedes 4.x.
+* Incidentally, script templates were updated not to include the triple-quote
+  escaping.
+
+-------------------------
+3.7.1 and 3.8.1 and 4.0.1
+-------------------------
+
+* `Issue #213 <https://bitbucket.org/pypa/setuptools/issue/213>`_: Use legacy StringIO behavior for compatibility under pbr.
+* `Issue #218 <https://bitbucket.org/pypa/setuptools/issue/218>`_: Setuptools 3.8.1 superseded 4.0.1, and 4.x was removed

+---
+
+* `Issue #195 <https://bitbucket.org/pypa/setuptools/issue/195>`_: Follow symbolic links in find_packages (restoring behavior
+  broken in 3.4).
+* `Issue #197 <https://bitbucket.org/pypa/setuptools/issue/197>`_: On Python 3.1, PKG-INFO is now saved in a UTF-8 encoding instead
+  of ``sys.getpreferredencoding`` to match the behavior on Python 2.6-3.4.
+* `Issue #192 <https://bitbucket.org/pypa/setuptools/issue/192>`_: Preferred bootstrap location is now
+  https://bootstrap.pypa.io/ez_setup.py (mirrored from former location).
+
+-----
+3.4.4
+-----
+
+* `Issue #184 <https://bitbucket.org/pypa/setuptools/issue/184>`_: Correct failure where find_package over-matched packages

+* `Issue #177 <https://bitbucket.org/pypa/setuptools/issue/177>`_: Now assume most common invocation to install command on
+  platforms/environments without stack support (issuing a warning). Setuptools

+
+---
+3.2
+---
+
+* `Pull Request #39 <https://bitbucket.org/pypa/setuptools/pull-request/39>`_: Add support for C++ targets from Cython ``.pyx`` files.

+-----
+3.0.1
+-----
+
+* `Issue #157 <https://bitbucket.org/pypa/setuptools/issue/157>`_: Restore support for Python 2.6 in bootstrap script where
+  ``zipfile.ZipFile`` does not yet have support for context managers.
+
+---
+3.0
+---
+
+* `Issue #125 <https://bitbucket.org/pypa/setuptools/issue/125>`_: Prevent Subversion support from creating a ~/.subversion
+  directory just for checking the presence of a Subversion repository.
+* `Issue #12 <https://bitbucket.org/pypa/setuptools/issue/12>`_: Namespace packages are now imported lazily.  That is, the mere
+  declaration of a namespace package in an egg on ``sys.path`` no longer
+  causes it to be imported when ``pkg_resources`` is imported.  Note that this
+  change means that all of a namespace package's ``__init__.py`` files must
+  include a ``declare_namespace()`` call in order to ensure that they will be
+  handled properly at runtime.  In 2.x it was possible to get away without
+  including the declaration, but only at the cost of forcing namespace
+  packages to be imported early, which 3.0 no longer does.
+* `Issue #148 <https://bitbucket.org/pypa/setuptools/issue/148>`_: When building (bdist_egg), setuptools no longer adds
+  ``__init__.py`` files to namespace packages. Any packages that rely on this
+  behavior will need to create ``__init__.py`` files and include the
+  ``declare_namespace()``.
+* `Issue #7 <https://bitbucket.org/pypa/setuptools/issue/7>`_: Setuptools itself is now distributed as a zip archive in addition to
+  tar archive. ez_setup.py now uses zip archive. This approach avoids the potential
+  security vulnerabilities presented by use of tar archives in ez_setup.py.
+  It also leverages the security features added to ZipFile.extract in Python 2.7.4.
+* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Removed deprecated Features functionality.
+* `Pull Request #28 <https://bitbucket.org/pypa/setuptools/pull-request/28>`_: Remove backport of ``_bytecode_filenames`` which is
+  available in Python 2.6 and later, but also has better compatibility with
+  Python 3 environments.

+* `Issue #41 <https://bitbucket.org/pypa/setuptools/issue/41>`_: Dropped support for Python 2.4 and Python 2.5. Clients requiring
+  setuptools for those versions of Python should use setuptools 1.x.
+* Removed ``setuptools.command.easy_install.HAS_USER_SITE``. Clients
+  expecting this boolean variable should use ``site.ENABLE_USER_SITE``
+  instead.
+* Removed ``pkg_resources.ImpWrapper``. Clients that expected this class
+  should use ``pkgutil.ImpImporter`` instead.
+
+-----
+1.4.2
+-----
+
+* `Issue #116 <https://bitbucket.org/pypa/setuptools/issue/116>`_: Correct TypeError when reading a local package index on Python
+  3.
+
+-----
+1.4.1
+-----
+
+* `Issue #114 <https://bitbucket.org/pypa/setuptools/issue/114>`_: Use ``sys.getfilesystemencoding`` for decoding config in
+  ``bdist_wininst`` distributions.
+
+* `Issue #105 <https://bitbucket.org/pypa/setuptools/issue/105>`_ and `Issue #113 <https://bitbucket.org/pypa/setuptools/issue/113>`_: Establish a more robust technique for
+  determining the terminal encoding::
+
+    1. Try ``getpreferredencoding``
+    2. If that returns US_ASCII or None, try the encoding from
+       ``getdefaultlocale``. If that encoding was a "fallback" because Python
+       could not figure it out from the environment or OS, encoding remains
+       unresolved.
+    3. If the encoding is resolved, then make sure Python actually implements
+       the encoding.
+    4. On the event of an error or unknown codec, revert to fallbacks
+       (UTF-8 on Darwin, ASCII on everything else).
+    5. On the encoding is 'mac-roman' on Darwin, use UTF-8 as 'mac-roman' was
+       a bug on older Python releases.
+
+    On a side note, it would seem that the encoding only matters for when SVN
+    does not yet support ``--xml`` and when getting repository and svn version
+    numbers. The ``--xml`` technique should yield UTF-8 according to some
+    messages on the SVN mailing lists. So if the version numbers are always
+    7-bit ASCII clean, it may be best to only support the file parsing methods
+    for legacy SVN releases and support for SVN without the subprocess command
+    would simple go away as support for the older SVNs does.

+1.4
+---
+
+* `Issue #27 <https://bitbucket.org/pypa/setuptools/issue/27>`_: ``easy_install`` will now use credentials from .pypirc if

+
+* Address security vulnerability in SSL match_hostname check as reported in

+* Correct NameError in ``ssl_support`` module (``socket.error``).
+
+---
+1.2
+---
+
+* `Issue #26 <https://bitbucket.org/pypa/setuptools/issue/26>`_: Add support for SVN 1.7. Special thanks to Philip Thiem for the
+  contribution.
+* `Issue #93 <https://bitbucket.org/pypa/setuptools/issue/93>`_: Wheels are now distributed with every release. Note that as
+  reported in `Issue #108 <https://bitbucket.org/pypa/setuptools/issue/108>`_, as of Pip 1.4, scripts aren't installed properly
+  from wheels. Therefore, if using Pip to install setuptools from a wheel,
+  the ``easy_install`` command will not be available.
+* Setuptools "natural" launcher support, introduced in 1.0, is now officially
+  supported.
+
+-----
+1.1.7
+-----
+
+* Fixed behavior of NameError handling in 'script template (dev).py' (script
+  launcher for 'develop' installs).
+* ``ez_setup.py`` now ensures partial downloads are cleaned up following
+  a failed download.
+* `Distribute #363 <https://bitbucket.org/tarek/distribute/issue/363>`_ and `Issue #55 <https://bitbucket.org/pypa/setuptools/issue/55>`_: Skip an sdist test that fails on locales
+  other than UTF-8.
+
+-----
+1.1.6
+-----
+
+* `Distribute #349 <https://bitbucket.org/tarek/distribute/issue/349>`_: ``sandbox.execfile`` now opens the target file in binary

+1.1.5
+-----
+
+* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Second attempt at fix (logic was reversed).
+

+1.1.4
+-----
+
+* `Issue #77 <https://bitbucket.org/pypa/setuptools/issue/77>`_: Fix error in upload command (Python 2.4).
+

+1.1.3
+-----
+
+* Fix NameError in previous patch.
+
+-----
+1.1.2
+-----
+
+* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Correct issue where 404 errors are returned for URLs with
+  fragments in them (such as #egg=).
+
+-----
+1.1.1
+-----
+
+* `Issue #75 <https://bitbucket.org/pypa/setuptools/issue/75>`_: Add ``--insecure`` option to ez_setup.py to accommodate
+  environments where a trusted SSL connection cannot be validated.
+* `Issue #76 <https://bitbucket.org/pypa/setuptools/issue/76>`_: Fix AttributeError in upload command with Python 2.4.
+
+---
+1.1
+---
+
+* `Issue #71 <https://bitbucket.org/pypa/setuptools/issue/71>`_ (`Distribute #333 <https://bitbucket.org/tarek/distribute/issue/333>`_): EasyInstall now puts less emphasis on the
+  condition when a host is blocked via ``--allow-hosts``.
+* `Issue #72 <https://bitbucket.org/pypa/setuptools/issue/72>`_: Restored Python 2.4 compatibility in ``ez_setup.py``.
+
+---
+1.0
+---
+
+* `Issue #60 <https://bitbucket.org/pypa/setuptools/issue/60>`_: On Windows, Setuptools supports deferring to another launcher,
+  such as Vinay Sajip's `pylauncher <https://bitbucket.org/pypa/pylauncher>`_
+  (included with Python 3.3) to launch console and GUI scripts and not install
+  its own launcher executables. This experimental functionality is currently
+  only enabled if  the ``SETUPTOOLS_LAUNCHER`` environment variable is set to
+  "natural". In the future, this behavior may become default, but only after
+  it has matured and seen substantial adoption. The ``SETUPTOOLS_LAUNCHER``
+  also accepts "executable" to force the default behavior of creating launcher
+  executables.
+* `Issue #63 <https://bitbucket.org/pypa/setuptools/issue/63>`_: Bootstrap script (ez_setup.py) now prefers Powershell, curl, or
+  wget for retrieving the Setuptools tarball for improved security of the
+  install. The script will still fall back to a simple ``urlopen`` on
+  platforms that do not have these tools.
+* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Deprecated the ``Features`` functionality.
+* `Issue #52 <https://bitbucket.org/pypa/setuptools/issue/52>`_: In ``VerifyingHTTPSConn``, handle a tunnelled (proxied)
+  connection.
+
+Backward-Incompatible Changes
+=============================
+
+This release includes a couple of backward-incompatible changes, but most if
+not all users will find 1.0 a drop-in replacement for 0.9.
+
+* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: Normalized API of environment marker support. Specifically,
+  removed line number and filename from SyntaxErrors when returned from
+  `pkg_resources.invalid_marker`. Any clients depending on the specific
+  string representation of exceptions returned by that function may need to
+  be updated to account for this change.
+* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: SyntaxErrors generated by `pkg_resources.invalid_marker` are
+  normalized for cross-implementation consistency.
+* Removed ``--ignore-conflicts-at-my-risk`` and ``--delete-conflicting``
+  options to easy_install. These options have been deprecated since 0.6a11.
+
+-----
+0.9.8
+-----
+
+* `Issue #53 <https://bitbucket.org/pypa/setuptools/issue/53>`_: Fix NameErrors in `_vcs_split_rev_from_url`.

+  referenced by bookmark.
+* Add underscore-separated keys to environment markers (markerlib).
+
+-----
+0.9.6
+-----
+
+* `Issue #44 <https://bitbucket.org/pypa/setuptools/issue/44>`_: Test failure on Python 2.4 when MD5 hash doesn't have a `.name`

+
+-----
+0.9.2
+-----
+
+* `Issue #42 <https://bitbucket.org/pypa/setuptools/issue/42>`_: Fix regression where blank checksums would trigger an
+  ``AttributeError``.

+
+* Code base now runs on Python 2.4 - Python 3.3 without Python 2to3
+  conversion.

+* Merged Setuptools and Distribute. See docs/merge.txt for details.
+
+Added several features that were slated for setuptools 0.6c12:
+
+* Index URL now defaults to HTTPS.
+* Added experimental environment marker support. Now clients may designate a
+  PEP-426 environment marker for "extra" dependencies. Setuptools uses this
+  feature in ``setup.py`` for optional SSL and certificate validation support
+  on older platforms. Based on Distutils-SIG discussions, the syntax is
+  somewhat tentative. There should probably be a PEP with a firmer spec before
+  the feature should be considered suitable for use.
+* Added support for SSL certificate validation when installing packages from
+  an HTTPS service.

+  as the system encoding is UTF-8 or the IO encoding is specified in the
+  environment, i.e.::
+
+     PYTHONIOENCODING=utf8 pip install numpy
+
+* Fix for encoding issue when installing from Windows executable on Python 3.
+* `Distribute #323 <https://bitbucket.org/tarek/distribute/issue/323>`_: Allow `setup_requires` requirements to supercede installed
+  requirements. Added some new keyword arguments to existing pkg_resources
+  methods. Also had to updated how __path__ is handled for namespace packages
+  to ensure that when a new egg distribution containing a namespace package is
+  placed on sys.path, the entries in __path__ are found in the same order they
+  would have been in had that egg been on the path when pkg_resources was
+  first imported.

+* `Distribute #100 <https://bitbucket.org/tarek/distribute/issue/100>`_: making sure there's no SandboxViolation when
+  the setup script patches setuptools.
+
+-----
+0.6.8
+-----
+
+* Added "check_packages" in dist. (added in Setuptools 0.6c11)
+* Fixed the DONT_PATCH_SETUPTOOLS state.
+
+-----
+0.6.7
+-----
+
+* `Distribute #58 <https://bitbucket.org/tarek/distribute/issue/58>`_: Added --user support to the develop command
+* `Distribute #11 <https://bitbucket.org/tarek/distribute/issue/11>`_: Generated scripts now wrap their call to the script entry point
+  in the standard "if name == 'main'"
+* Added the 'DONT_PATCH_SETUPTOOLS' environment variable, so virtualenv
+  can drive an installation that doesn't patch a global setuptools.
+* Reviewed unladen-swallow specific change from
+  http://code.google.com/p/unladen-swallow/source/detail?spec=svn875&r=719
+  and determined that it no longer applies. Distribute should work fine with
+  Unladen Swallow 2009Q3.
+* `Distribute #21 <https://bitbucket.org/tarek/distribute/issue/21>`_: Allow PackageIndex.open_url to gracefully handle all cases of a
+  httplib.HTTPException instead of just InvalidURL and BadStatusLine.
+* Removed virtual-python.py from this distribution and updated documentation
+  to point to the actively maintained virtualenv instead.
+* `Distribute #64 <https://bitbucket.org/tarek/distribute/issue/64>`_: use_setuptools no longer rebuilds the distribute egg every
+  time it is run
+* use_setuptools now properly respects the requested version
+* use_setuptools will no longer try to import a distribute egg for the
+  wrong Python version
+* `Distribute #74 <https://bitbucket.org/tarek/distribute/issue/74>`_: no_fake should be True by default.
+* `Distribute #72 <https://bitbucket.org/tarek/distribute/issue/72>`_: avoid a bootstrapping issue with easy_install -U
+
+-----
+0.6.6
+-----
+
+* Unified the bootstrap file so it works on both py2.x and py3k without 2to3
+  (patch by Holger Krekel)
+
+-----
+0.6.5
+-----
+
+* `Distribute #65 <https://bitbucket.org/tarek/distribute/issue/65>`_: cli.exe and gui.exe are now generated at build time,
+  depending on the platform in use.
+
+* `Distribute #67 <https://bitbucket.org/tarek/distribute/issue/67>`_: Fixed doc typo (PEP 381/382)
+
+* Distribute no longer shadows setuptools if we require a 0.7-series
+  setuptools.  And an error is raised when installing a 0.7 setuptools with
+  distribute.
+
+* When run from within buildout, no attempt is made to modify an existing
+  setuptools egg, whether in a shared egg directory or a system setuptools.
+
+* Fixed a hole in sandboxing allowing builtin file to write outside of
+  the sandbox.
+
+-----
+0.6.4
+-----
+
+* Added the generation of `distribute_setup_3k.py` during the release.
+  This closes `Distribute #52 <https://bitbucket.org/tarek/distribute/issue/52>`_.
+
+* Added an upload_docs command to easily upload project documentation to
+  PyPI's https://pythonhosted.org. This close issue `Distribute #56 <https://bitbucket.org/tarek/distribute/issue/56>`_.
+
+* Fixed a bootstrap bug on the use_setuptools() API.

+
+-----
+0.6c9
+-----
+
+ * Fixed a missing files problem when using Windows source distributions on
+   non-Windows platforms, due to distutils not handling manifest file line
+   endings correctly.
+
+ * Updated Pyrex support to work with Pyrex 0.9.6 and higher.
+
+ * Minor changes for Jython compatibility, including skipping tests that can't
+   work on Jython.
+
+ * Fixed not installing eggs in ``install_requires`` if they were also used for
+   ``setup_requires`` or ``tests_require``.
+
+ * Fixed not fetching eggs in ``install_requires`` when running tests.
+
+ * Allow ``ez_setup.use_setuptools()`` to upgrade existing setuptools
+   installations when called from a standalone ``setup.py``.
+
+ * Added a warning if a namespace package is declared, but its parent package
+   is not also declared as a namespace.
+
+ * Support Subversion 1.5
+
+ * Removed use of deprecated ``md5`` module if ``hashlib`` is available
+
+ * Fixed ``bdist_wininst upload`` trying to upload the ``.exe`` twice
+
+ * Fixed ``bdist_egg`` putting a ``native_libs.txt`` in the source package's
+   ``.egg-info``, when it should only be in the built egg's ``EGG-INFO``.
+
+ * Ensure that _full_name is set on all shared libs before extensions are
+   checked for shared lib usage.  (Fixes a bug in the experimental shared
+   library build support.)
+
+ * Fix to allow unpacked eggs containing native libraries to fail more
+   gracefully under Google App Engine (with an ``ImportError`` loading the
+   C-based module, instead of getting a ``NameError``).
+
+-----
+0.6c7
+-----
+
+ * Fixed ``distutils.filelist.findall()`` crashing on broken symlinks, and
+   ``egg_info`` command failing on new, uncommitted SVN directories.
+
+ * Fix import problems with nested namespace packages installed via
+   ``--root`` or ``--single-version-externally-managed``, due to the
+   parent package not having the child package as an attribute.
+
+-----
+0.6c6
+-----
+
+ * Added ``--egg-path`` option to ``develop`` command, allowing you to force
+   ``.egg-link`` files to use relative paths (allowing them to be shared across
+   platforms on a networked drive).
+
+ * Fix not building binary RPMs correctly.
+
+ * Fix "eggsecutables" (such as setuptools' own egg) only being runnable with
+   bash-compatible shells.
+
+ * Fix ``#!`` parsing problems in Windows ``.exe`` script wrappers, when there
+   was whitespace inside a quoted argument or at the end of the ``#!`` line
+   (a regression introduced in 0.6c4).
+
+ * Fix ``test`` command possibly failing if an older version of the project
+   being tested was installed on ``sys.path`` ahead of the test source
+   directory.
+
+ * Fix ``find_packages()`` treating ``ez_setup`` and directories with ``.`` in
+   their names as packages.
+
+-----
+0.6c5
+-----
+
+ * Fix uploaded ``bdist_rpm`` packages being described as ``bdist_egg``
+   packages under Python versions less than 2.5.
+
+ * Fix uploaded ``bdist_wininst`` packages being described as suitable for
+   "any" version by Python 2.5, even if a ``--target-version`` was specified.
+
+-----
+0.6c4
+-----
+
+ * Overhauled Windows script wrapping to support ``bdist_wininst`` better.
+   Scripts installed with ``bdist_wininst`` will always use ``#!python.exe`` or
+   ``#!pythonw.exe`` as the executable name (even when built on non-Windows
+   platforms!), and the wrappers will look for the executable in the script's
+   parent directory (which should find the right version of Python).
+
+ * Fix ``upload`` command not uploading files built by ``bdist_rpm`` or
+   ``bdist_wininst`` under Python 2.3 and 2.4.
+
+ * Add support for "eggsecutable" headers: a ``#!/bin/sh`` script that is
+   prepended to an ``.egg`` file to allow it to be run as a script on Unix-ish
+   platforms.  (This is mainly so that setuptools itself can have a single-file
+   installer on Unix, without doing multiple downloads, dealing with firewalls,
+   etc.)
+
+ * Fix problem with empty revision numbers in Subversion 1.4 ``entries`` files
+
+ * Use cross-platform relative paths in ``easy-install.pth`` when doing
+   ``develop`` and the source directory is a subdirectory of the installation
+   target directory.
+
+ * Fix a problem installing eggs with a system packaging tool if the project
+   contained an implicit namespace package; for example if the ``setup()``
+   listed a namespace package ``foo.bar`` without explicitly listing ``foo``
+   as a namespace package.
+
+-----
+0.6c3
+-----
+
+ * Fixed breakages caused by Subversion 1.4's new "working copy" format
+
+-----
+0.6c2
+-----
+
+ * The ``ez_setup`` module displays the conflicting version of setuptools (and
+   its installation location) when a script requests a version that's not
+   available.
+
+ * Running ``setup.py develop`` on a setuptools-using project will now install
+   setuptools if needed, instead of only downloading the egg.
+
+-----
+0.6c1
+-----
+
+ * Fixed ``AttributeError`` when trying to download a ``setup_requires``
+   dependency when a distribution lacks a ``dependency_links`` setting.
+
+ * Made ``zip-safe`` and ``not-zip-safe`` flag files contain a single byte, so
+   as to play better with packaging tools that complain about zero-length
+   files.
+
+ * Made ``setup.py develop`` respect the ``--no-deps`` option, which it
+   previously was ignoring.
+
+ * Support ``extra_path`` option to ``setup()`` when ``install`` is run in
+   backward-compatibility mode.
+
+ * Source distributions now always include a ``setup.cfg`` file that explicitly
+   sets ``egg_info`` options such that they produce an identical version number
+   to the source distribution's version number.  (Previously, the default
+   version number could be different due to the use of ``--tag-date``, or if
+   the version was overridden on the command line that built the source
+   distribution.)
+
+-----
+0.6b4
+-----
+
+ * Fix ``register`` not obeying name/version set by ``egg_info`` command, if
+   ``egg_info`` wasn't explicitly run first on the same command line.
+
+ * Added ``--no-date`` and ``--no-svn-revision`` options to ``egg_info``
+   command, to allow suppressing tags configured in ``setup.cfg``.
+
+ * Fixed redundant warnings about missing ``README`` file(s); it should now
+   appear only if you are actually a source distribution.
+
+-----
+0.6b3
+-----
+
+ * Fix ``bdist_egg`` not including files in subdirectories of ``.egg-info``.
+
+ * Allow ``.py`` files found by the ``include_package_data`` option to be
+   automatically included.  Remove duplicate data file matches if both
+   ``include_package_data`` and ``package_data`` are used to refer to the same
+   files.
+
+-----
+0.6b1
+-----
+
+ * Strip ``module`` from the end of compiled extension modules when computing
+   the name of a ``.py`` loader/wrapper.  (Python's import machinery ignores
+   this suffix when searching for an extension module.)
+
+------
+0.6a11
+------
+
+ * Added ``test_loader`` keyword to support custom test loaders
+
+ * Added ``setuptools.file_finders`` entry point group to allow implementing
+   revision control plugins.
+
+ * Added ``--identity`` option to ``upload`` command.
+
+ * Added ``dependency_links`` to allow specifying URLs for ``--find-links``.
+
+ * Enhanced test loader to scan packages as well as modules, and call
+   ``additional_tests()`` if present to get non-unittest tests.
+
+ * Support namespace packages in conjunction with system packagers, by omitting
+   the installation of any ``__init__.py`` files for namespace packages, and
+   adding a special ``.pth`` file to create a working package in
+   ``sys.modules``.
+
+ * Made ``--single-version-externally-managed`` automatic when ``--root`` is
+   used, so that most system packagers won't require special support for
+   setuptools.
+
+ * Fixed ``setup_requires``, ``tests_require``, etc. not using ``setup.cfg`` or
+   other configuration files for their option defaults when installing, and
+   also made the install use ``--multi-version`` mode so that the project
+   directory doesn't need to support .pth files.
+
+ * ``MANIFEST.in`` is now forcibly closed when any errors occur while reading
+   it.  Previously, the file could be left open and the actual error would be
+   masked by problems trying to remove the open file on Windows systems.
+
+------
+0.6a10
+------
+
+ * Fixed the ``develop`` command ignoring ``--find-links``.
+
+-----
+0.6a9
+-----
+
+ * The ``sdist`` command no longer uses the traditional ``MANIFEST`` file to
+   create source distributions.  ``MANIFEST.in`` is still read and processed,
+   as are the standard defaults and pruning.  But the manifest is built inside
+   the project's ``.egg-info`` directory as ``SOURCES.txt``, and it is rebuilt
+   every time the ``egg_info`` command is run.
+
+ * Added the ``include_package_data`` keyword to ``setup()``, allowing you to
+   automatically include any package data listed in revision control or
+   ``MANIFEST.in``
+
+ * Added the ``exclude_package_data`` keyword to ``setup()``, allowing you to
+   trim back files included via the ``package_data`` and
+   ``include_package_data`` options.
+
+ * Fixed ``--tag-svn-revision`` not working when run from a source
+   distribution.
+
+ * Added warning for namespace packages with missing ``declare_namespace()``
+
+ * Added ``tests_require`` keyword to ``setup()``, so that e.g. packages
+   requiring ``nose`` to run unit tests can make this dependency optional
+   unless the ``test`` command is run.
+
+ * Made all commands that use ``easy_install`` respect its configuration
+   options, as this was causing some problems with ``setup.py install``.
+
+ * Added an ``unpack_directory()`` driver to ``setuptools.archive_util``, so
+   that you can process a directory tree through a processing filter as if it
+   were a zipfile or tarfile.
+
+ * Added an internal ``install_egg_info`` command to use as part of old-style
+   ``install`` operations, that installs an ``.egg-info`` directory with the
+   package.
+
+ * Added a ``--single-version-externally-managed`` option to the ``install``
+   command so that you can more easily wrap a "flat" egg in a system package.
+
+ * Enhanced ``bdist_rpm`` so that it installs single-version eggs that
+   don't rely on a ``.pth`` file.  The ``--no-egg`` option has been removed,
+   since all RPMs are now built in a more backwards-compatible format.
+
+ * Support full roundtrip translation of eggs to and from ``bdist_wininst``
+   format.  Running ``bdist_wininst`` on a setuptools-based package wraps the
+   egg in an .exe that will safely install it as an egg (i.e., with metadata
+   and entry-point wrapper scripts), and ``easy_install`` can turn the .exe
+   back into an ``.egg`` file or directory and install it as such.
+
+
+-----
+0.6a8
+-----
+
+ * Fixed some problems building extensions when Pyrex was installed, especially
+   with Python 2.4 and/or packages using SWIG.
+
+ * Made ``develop`` command accept all the same options as ``easy_install``,
+   and use the ``easy_install`` command's configuration settings as defaults.
+
+ * Made ``egg_info --tag-svn-revision`` fall back to extracting the revision
+   number from ``PKG-INFO`` in case it is being run on a source distribution of
+   a snapshot taken from a Subversion-based project.
+
+ * Automatically detect ``.dll``, ``.so`` and ``.dylib`` files that are being
+   installed as data, adding them to ``native_libs.txt`` automatically.
+
+ * Fixed some problems with fresh checkouts of projects that don't include
+   ``.egg-info/PKG-INFO`` under revision control and put the project's source
+   code directly in the project directory.  If such a package had any
+   requirements that get processed before the ``egg_info`` command can be run,
+   the setup scripts would fail with a "Missing 'Version:' header and/or
+   PKG-INFO file" error, because the egg runtime interpreted the unbuilt
+   metadata in a directory on ``sys.path`` (i.e. the current directory) as
+   being a corrupted egg.  Setuptools now monkeypatches the distribution
+   metadata cache to pretend that the egg has valid version information, until
+   it has a chance to make it actually be so (via the ``egg_info`` command).
+
+-----
+0.6a5
+-----
+
+ * Fixed missing gui/cli .exe files in distribution.  Fixed bugs in tests.
+
+-----
+0.6a3
+-----
+
+ * Added ``gui_scripts`` entry point group to allow installing GUI scripts
+   on Windows and other platforms.  (The special handling is only for Windows;
+   other platforms are treated the same as for ``console_scripts``.)
+
+-----
+0.6a2
+-----
+
+ * Added ``console_scripts`` entry point group to allow installing scripts
+   without the need to create separate script files.  On Windows, console
+   scripts get an ``.exe`` wrapper so you can just type their name.  On other
+   platforms, the scripts are written without a file extension.
+
+-----
+0.6a1
+-----
+
+ * Added support for building "old-style" RPMs that don't install an egg for
+   the target package, using a ``--no-egg`` option.
+
+ * The ``build_ext`` command now works better when using the ``--inplace``
+   option and multiple Python versions.  It now makes sure that all extensions
+   match the current Python version, even if newer copies were built for a
+   different Python version.
+
+ * The ``upload`` command no longer attaches an extra ``.zip`` when uploading
+   eggs, as PyPI now supports egg uploads without trickery.
+
+ * The ``ez_setup`` script/module now displays a warning before downloading
+   the setuptools egg, and attempts to check the downloaded egg against an
+   internal MD5 checksum table.
+
+ * Fixed the ``--tag-svn-revision`` option of ``egg_info`` not finding the
+   latest revision number; it was using the revision number of the directory
+   containing ``setup.py``, not the highest revision number in the project.
+
+ * Added ``eager_resources`` setup argument
+
+ * The ``sdist`` command now recognizes Subversion "deleted file" entries and
+   does not include them in source distributions.
+
+ * ``setuptools`` now embeds itself more thoroughly into the distutils, so that
+   other distutils extensions (e.g. py2exe, py2app) will subclass setuptools'
+   versions of things, rather than the native distutils ones.
+
+ * Added ``entry_points`` and ``setup_requires`` arguments to ``setup()``;
+   ``setup_requires`` allows you to automatically find and download packages
+   that are needed in order to *build* your project (as opposed to running it).
+
+ * ``setuptools`` now finds its commands, ``setup()`` argument validators, and
+   metadata writers using entry points, so that they can be extended by
+   third-party packages.  See `Creating distutils Extensions
+   <http://pythonhosted.org/setuptools/setuptools.html#creating-distutils-extensions>`_
+   for more details.
+
+ * The vestigial ``depends`` command has been removed.  It was never finished
+   or documented, and never would have worked without EasyInstall - which it
+   pre-dated and was never compatible with.
+
+------
+0.5a12
+------
+
+ * The zip-safety scanner now checks for modules that might be used with
+   ``python -m``, and marks them as unsafe for zipping, since Python 2.4 can't
+   handle ``-m`` on zipped modules.
+
+------
+0.5a11
+------
+
+ * Fix breakage of the "develop" command that was caused by the addition of
+   ``--always-unzip`` to the ``easy_install`` command.
+
+-----
+0.5a9
+-----
+
+ * Include ``svn:externals`` directories in source distributions as well as
+   normal subversion-controlled files and directories.
+
+ * Added ``exclude=patternlist`` option to ``setuptools.find_packages()``
+
+ * Changed --tag-svn-revision to include an "r" in front of the revision number
+   for better readability.
+
+ * Added ability to build eggs without including source files (except for any
+   scripts, of course), using the ``--exclude-source-files`` option to
+   ``bdist_egg``.
+
+ * ``setup.py install`` now automatically detects when an "unmanaged" package
+   or module is going to be on ``sys.path`` ahead of a package being installed,
+   thereby preventing the newer version from being imported.  If this occurs,
+   a warning message is output to ``sys.stderr``, but installation proceeds
+   anyway.  The warning message informs the user what files or directories
+   need deleting, and advises them they can also use EasyInstall (with the
+   ``--delete-conflicting`` option) to do it automatically.
+
+ * The ``egg_info`` command now adds a ``top_level.txt`` file to the metadata
+   directory that lists all top-level modules and packages in the distribution.
+   This is used by the ``easy_install`` command to find possibly-conflicting
+   "unmanaged" packages when installing the distribution.
+
+ * Added ``zip_safe`` and ``namespace_packages`` arguments to ``setup()``.
+   Added package analysis to determine zip-safety if the ``zip_safe`` flag
+   is not given, and advise the author regarding what code might need changing.
+
+ * Fixed the swapped ``-d`` and ``-b`` options of ``bdist_egg``.
+
+-----
+0.5a8
+-----
+
+ * The "egg_info" command now always sets the distribution metadata to "safe"
+   forms of the distribution name and version, so that distribution files will
+   be generated with parseable names (i.e., ones that don't include '-' in the
+   name or version).  Also, this means that if you use the various ``--tag``
+   options of "egg_info", any distributions generated will use the tags in the
+   version, not just egg distributions.
+
+ * Added support for defining command aliases in distutils configuration files,
+   under the "[aliases]" section.  To prevent recursion and to allow aliases to
+   call the command of the same name, a given alias can be expanded only once
+   per command-line invocation.  You can define new aliases with the "alias"
+   command, either for the local, global, or per-user configuration.
+
+ * Added "rotate" command to delete old distribution files, given a set of
+   patterns to match and the number of files to keep.  (Keeps the most
+   recently-modified distribution files matching each pattern.)
+
+ * Added "saveopts" command that saves all command-line options for the current
+   invocation to the local, global, or per-user configuration file.  Useful for
+   setting defaults without having to hand-edit a configuration file.
+
+ * Added a "setopt" command that sets a single option in a specified distutils
+   configuration file.
+
+-----
+0.5a7
+-----
+
+ * Added "upload" support for egg and source distributions, including a bug
+   fix for "upload" and a temporary workaround for lack of .egg support in
+   PyPI.
+
+-----
+0.5a6
+-----
+
+ * Beefed up the "sdist" command so that if you don't have a MANIFEST.in, it
+   will include all files under revision control (CVS or Subversion) in the
+   current directory, and it will regenerate the list every time you create a
+   source distribution, not just when you tell it to.  This should make the
+   default "do what you mean" more often than the distutils' default behavior
+   did, while still retaining the old behavior in the presence of MANIFEST.in.
+
+ * Fixed the "develop" command always updating .pth files, even if you
+   specified ``-n`` or ``--dry-run``.
+
+ * Slightly changed the format of the generated version when you use
+   ``--tag-build`` on the "egg_info" command, so that you can make tagged
+   revisions compare *lower* than the version specified in setup.py (e.g. by
+   using ``--tag-build=dev``).
+
+-----
+0.5a5
+-----
+
+ * Added ``develop`` command to ``setuptools``-based packages.  This command
+   installs an ``.egg-link`` pointing to the package's source directory, and
+   script wrappers that ``execfile()`` the source versions of the package's
+   scripts.  This lets you put your development checkout(s) on sys.path without
+   having to actually install them.  (To uninstall the link, use
+   use ``setup.py develop --uninstall``.)
+
+ * Added ``egg_info`` command to ``setuptools``-based packages.  This command
+   just creates or updates the "projectname.egg-info" directory, without
+   building an egg.  (It's used by the ``bdist_egg``, ``test``, and ``develop``
+   commands.)
+
+ * Enhanced the ``test`` command so that it doesn't install the package, but
+   instead builds any C extensions in-place, updates the ``.egg-info``
+   metadata, adds the source directory to ``sys.path``, and runs the tests
+   directly on the source.  This avoids an "unmanaged" installation of the
+   package to ``site-packages`` or elsewhere.
+
+ * Made ``easy_install`` a standard ``setuptools`` command, moving it from
+   the ``easy_install`` module to ``setuptools.command.easy_install``.  Note
+   that if you were importing or extending it, you must now change your imports
+   accordingly.  ``easy_install.py`` is still installed as a script, but not as
+   a module.
+
+-----
+0.5a4
+-----
+
+ * Setup scripts using setuptools can now list their dependencies directly in
+   the setup.py file, without having to manually create a ``depends.txt`` file.
+   The ``install_requires`` and ``extras_require`` arguments to ``setup()``
+   are used to create a dependencies file automatically.  If you are manually
+   creating ``depends.txt`` right now, please switch to using these setup
+   arguments as soon as practical, because ``depends.txt`` support will be
+   removed in the 0.6 release cycle.  For documentation on the new arguments,
+   see the ``setuptools.dist.Distribution`` class.
+
+ * Setup scripts using setuptools now always install using ``easy_install``
+   internally, for ease of uninstallation and upgrading.
+
+-----
+0.5a1
+-----
+
+ * Added support for "self-installation" bootstrapping.  Packages can now
+   include ``ez_setup.py`` in their source distribution, and add the following
+   to their ``setup.py``, in order to automatically bootstrap installation of
+   setuptools as part of their setup process::
+
+    from ez_setup import use_setuptools
+    use_setuptools()
+
+    from setuptools import setup
+    # etc...
+
+-----
+0.4a2
+-----
+
+ * Added ``ez_setup.py`` installer/bootstrap script to make initial setuptools
+   installation easier, and to allow distributions using setuptools to avoid
+   having to include setuptools in their source distribution.
+
+ * All downloads are now managed by the ``PackageIndex`` class (which is now
+   subclassable and replaceable), so that embedders can more easily override
+   download logic, give download progress reports, etc.  The class has also
+   been moved to the new ``setuptools.package_index`` module.
+
+ * The ``Installer`` class no longer handles downloading, manages a temporary
+   directory, or tracks the ``zip_ok`` option.  Downloading is now handled
+   by ``PackageIndex``, and ``Installer`` has become an ``easy_install``
+   command class based on ``setuptools.Command``.
+
+ * There is a new ``setuptools.sandbox.run_setup()`` API to invoke a setup
+   script in a directory sandbox, and a new ``setuptools.archive_util`` module
+   with an ``unpack_archive()`` API.  These were split out of EasyInstall to
+   allow reuse by other tools and applications.
+
+ * ``setuptools.Command`` now supports reinitializing commands using keyword
+   arguments to set/reset options.  Also, ``Command`` subclasses can now set
+   their ``command_consumes_arguments`` attribute to ``True`` in order to
+   receive an ``args`` option containing the rest of the command line.
+
+-----
+0.3a2
+-----
+
+ * Added new options to ``bdist_egg`` to allow tagging the egg's version number
+   with a subversion revision number, the current date, or an explicit tag
+   value.  Run ``setup.py bdist_egg --help`` to get more information.
+
+ * Misc. bug fixes
+
+-----
+0.3a1
+-----
+
+ * Initial release.

+
+    zipimport.zipimporter objects are Python loaders charged with importing
+    data packaged inside zip archives. If stale loaders referencing the
+    original distribution, are left behind, they can fail to load modules from
+    the replacement distribution. E.g. if an old zipimport.zipimporter instance
+    is used to load data from a new zipped egg archive, it may cause the

+    archive directory information. This, of course, assumes that the

+class Distribution(_Distribution):
+    """Distribution with support for features, tests, and package data
+
+    This is an enhanced version of 'distutils.dist.Distribution' that
+    effectively adds the following new optional keyword arguments to 'setup()':
+
+     'install_requires' -- a string or sequence of strings specifying project
+        versions that the distribution requires when installed, in the format
+        used by 'pkg_resources.require()'.  They will be installed
+        automatically when the package is installed.  If you wish to use
+        packages that are not available in PyPI, or want to give your users an
+        alternate download location, you can add a 'find_links' option to the
+        '[easy_install]' section of your project's 'setup.cfg' file, and then
+        setuptools will scan the listed web pages for links that satisfy the
+        requirements.
+
+     'extras_require' -- a dictionary mapping names of optional "extras" to the
+        additional requirement(s) that using those extras incurs. For example,
+        this::
+
+            extras_require = dict(reST = ["docutils>=0.3", "reSTedit"])
+
+        indicates that the distribution can optionally provide an extra
+        capability called "reST", but it can only be used if docutils and
+        reSTedit are installed.  If the user installs your package using
+        EasyInstall and requests one of your extras, the corresponding
+        additional requirements will be installed if needed.
+
+     'features' **deprecated** -- a dictionary mapping option names to
+        'setuptools.Feature'
+        objects.  Features are a portion of the distribution that can be
+        included or excluded based on user options, inter-feature dependencies,
+        and availability on the current system.  Excluded features are omitted
+        from all setup commands, including source and binary distributions, so
+        you can create multiple distributions from the same source tree.
+        Feature names should be valid Python identifiers, except that they may
+        contain the '-' (minus) sign.  Features can be included or excluded
+        via the command line options '--with-X' and '--without-X', where 'X' is
+        the name of the feature.  Whether a feature is included by default, and
+        whether you are allowed to control this from the command line, is
+        determined by the Feature object.  See the 'Feature' class for more
+        information.
+
+     'test_suite' -- the name of a test suite to run for the 'test' command.
+        If the user runs 'python setup.py test', the package will be installed,
+        and the named test suite will be run.  The format is the same as
+        would be used on a 'unittest.py' command line.  That is, it is the
+        dotted name of an object to import and call to generate a test suite.
+
+     'package_data' -- a dictionary mapping package names to lists of filenames
+        or globs to use to find data files contained in the named packages.
+        If the dictionary has filenames or globs listed under '""' (the empty
+        string), those names will be searched for in every package, in addition
+        to any names for the specific package.  Data files found using these
+        names/globs will be installed along with the package, in the same
+        location as the package.  Note that globs are allowed to reference
+        the contents of non-package subdirectories, as long as you use '/' as
+        a path separator.  (Globs are automatically converted to
+        platform-specific paths at runtime.)
+
+    In addition to these new keywords, this class also has several new methods
+    for manipulating the distribution's contents.  For example, the 'include()'
+    and 'exclude()' methods can be thought of as in-place add and subtract
+    commands that add or remove packages, modules, extensions, and so on from
+    the distribution.  They are used by the feature subsystem to configure the
+    distribution for the included and excluded features.

+

+
+      'description' -- a short, human readable description of the feature, to
+         be used in error messages, and option help messages.
+
+      'standard' -- if true, the feature is included by default if it is
+         available on the current system.  Otherwise, the feature is only
+         included if requested via a command line '--with-X' option, or if
+         another included feature requires it.  The default setting is 'False'.
+
+      'available' -- if true, the feature is available for installation on the
+         current system.  The default setting is 'True'.
+
+      'optional' -- if true, the feature's inclusion can be controlled from the
+         command line, using the '--with-X' or '--without-X' options.  If
+         false, the feature's inclusion status is determined automatically,
+         based on 'availabile', 'standard', and whether any other feature
+         requires it.  The default setting is 'True'.
+
+      'require_features' -- a string or sequence of strings naming features
+         that should also be included if this feature is included.  Defaults to
+         empty list.  May also contain 'Require' objects that should be
+         added/removed from the distribution.
+
+      'remove' -- a string or list of strings naming packages to be removed
+         from the distribution if this feature is *not* included.  If the
+         feature *is* included, this argument is ignored.  This argument exists
+         to support removing features that "crosscut" a distribution, such as
+         defining a 'tests' feature that removes all the 'tests' subpackages
+         provided by other features.  The default for this argument is an empty
+         list.  (Note: the named package(s) or modules must exist in the base
+         distribution when the 'setup()' function is initially called.)
+
+      other keywords -- any other keyword arguments are saved, and passed to
+         the distribution's 'include()' and 'exclude()' methods when the
+         feature is included or excluded, respectively.  So, for example, you
+         could pass 'packages=["a","b"]' to cause packages 'a' and 'b' to be
+         added or removed from the distribution as appropriate.
+
+    A feature must include at least one 'requires', 'remove', or other
+    keyword argument.  Otherwise, it can't affect the distribution in any way.
+    Note also that you can subclass 'Feature' to create your own specialized
+    feature types that modify the distribution in other ways when included or
+    excluded.  See the docstrings for the various methods here for more detail.
+    Aside from the methods, the only feature attributes that distributions look
+    at are 'description' and 'optional'.

+Metadata-Version: 1.1
+Name: simplejson
+Version: 3.6.4
+Summary: Simple, fast, extensible JSON encoder/decoder for Python
+Home-page: http://github.com/simplejson/simplejson
+Author: Bob Ippolito
+Author-email: bob@redivi.com
+License: MIT License
+Description: simplejson is a simple, fast, complete, correct and extensible
+        JSON <http://json.org> encoder and decoder for Python 2.5+
+        and Python 3.3+.  It is pure Python code with no dependencies,
+        but includes an optional C extension for a serious speed boost.
+        
+        The latest documentation for simplejson can be read online here:
+        http://simplejson.readthedocs.org/
+        
+        simplejson is the externally maintained development version of the
+        json library included with Python 2.6 and Python 3.0, but maintains
+        backwards compatibility with Python 2.5.
+        
+        The encoder can be specialized to provide serialization in any kind of
+        situation, without any special support by the objects to be serialized
+        (somewhat like pickle). This is best done with the ``default`` kwarg
+        to dumps.
+        
+        The decoder can handle incoming JSON strings of any specified encoding
+        (UTF-8 by default). It can also be specialized to post-process JSON
+        objects with the ``object_hook`` or ``object_pairs_hook`` kwargs. This
+        is particularly useful for implementing protocols such as JSON-RPC
+        that have a richer type system than JSON itself.
+        
+        For those of you that have legacy systems to maintain, there is a
+        very old fork of simplejson in the `python2.2`_ branch that supports
+        Python 2.2. This is based off of a very old version of simplejson,
+        is not maintained, and should only be used as a last resort.
+        
+        .. _python2.2: https://github.com/simplejson/simplejson/tree/python2.2

+r"""JSON (JavaScript Object Notation) <http://json.org> is a subset of
+JavaScript syntax (ECMA-262 3rd edition) used as a lightweight data
+interchange format.
+
+:mod:`simplejson` exposes an API familiar to users of the standard library
+:mod:`marshal` and :mod:`pickle` modules. It is the externally maintained
+version of the :mod:`json` library contained in Python 2.6, but maintains
+compatibility with Python 2.4 and Python 2.5 and (currently) has
+significant performance advantages, even without using the optional C
+extension for speedups.
+
+Encoding basic Python object hierarchies::
+
+    >>> import simplejson as json
+    >>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
+    '["foo", {"bar": ["baz", null, 1.0, 2]}]'
+    >>> print(json.dumps("\"foo\bar"))
+    "\"foo\bar"
+    >>> print(json.dumps(u'\u1234'))
+    "\u1234"
+    >>> print(json.dumps('\\'))
+    "\\"
+    >>> print(json.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True))
+    {"a": 0, "b": 0, "c": 0}
+    >>> from simplejson.compat import StringIO
+    >>> io = StringIO()
+    >>> json.dump(['streaming API'], io)
+    >>> io.getvalue()
+    '["streaming API"]'
+
+Compact encoding::
+
+    >>> import simplejson as json
+    >>> obj = [1,2,3,{'4': 5, '6': 7}]
+    >>> json.dumps(obj, separators=(',',':'), sort_keys=True)
+    '[1,2,3,{"4":5,"6":7}]'
+
+Pretty printing::
+
+    >>> import simplejson as json
+    >>> print(json.dumps({'4': 5, '6': 7}, sort_keys=True, indent='    '))
+    {
+        "4": 5,
+        "6": 7
+    }
+
+Decoding JSON::
+
+    >>> import simplejson as json
+    >>> obj = [u'foo', {u'bar': [u'baz', None, 1.0, 2]}]
+    >>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]') == obj
+    True
+    >>> json.loads('"\\"foo\\bar"') == u'"foo\x08ar'
+    True
+    >>> from simplejson.compat import StringIO
+    >>> io = StringIO('["streaming API"]')
+    >>> json.load(io)[0] == 'streaming API'
+    True
+
+Specializing JSON object decoding::
+
+    >>> import simplejson as json
+    >>> def as_complex(dct):
+    ...     if '__complex__' in dct:
+    ...         return complex(dct['real'], dct['imag'])
+    ...     return dct
+    ...
+    >>> json.loads('{"__complex__": true, "real": 1, "imag": 2}',
+    ...     object_hook=as_complex)
+    (1+2j)
+    >>> from decimal import Decimal
+    >>> json.loads('1.1', parse_float=Decimal) == Decimal('1.1')
+    True
+
+Specializing JSON object encoding::
+
+    >>> import simplejson as json
+    >>> def encode_complex(obj):
+    ...     if isinstance(obj, complex):
+    ...         return [obj.real, obj.imag]
+    ...     raise TypeError(repr(o) + " is not JSON serializable")
+    ...
+    >>> json.dumps(2 + 1j, default=encode_complex)
+    '[2.0, 1.0]'
+    >>> json.JSONEncoder(default=encode_complex).encode(2 + 1j)
+    '[2.0, 1.0]'
+    >>> ''.join(json.JSONEncoder(default=encode_complex).iterencode(2 + 1j))
+    '[2.0, 1.0]'
+
+
+Using simplejson.tool from the shell to validate and pretty-print::
+
+    $ echo '{"json":"obj"}' | python -m simplejson.tool
+    {
+        "json": "obj"
+    }
+    $ echo '{ 1.2:3.4}' | python -m simplejson.tool

+    will be skipped instead of raising a ``TypeError``.
+
+    If *ensure_ascii* is false, then the some chunks written to ``fp``

+    to cause an error.
+
+    If *check_circular* is false, then the circular reference check

+    result in an ``OverflowError`` (or worse).
+
+    If *allow_nan* is false, then it will be a ``ValueError`` to

+    will be pretty-printed with a newline followed by that string repeated

+    and is converted to a string with that many spaces.
+

+    If *tuple_as_array* is true (default: ``True``),
+    :class:`tuple` (and subclasses) will be encoded as JSON arrays.
+
+    If *bigint_as_string* is true (default: ``False``), ints 2**53 and higher
+    or lower than -2**53 will be encoded as strings. This is to avoid the

+    lossy operation that will not round-trip correctly and should be used
+    sparingly.
+
+    If *int_as_string_bitcount* is a positive number (n), then int of size
+    greater than or equal to 2**n or lower than or equal to -2**n will be

+    in alphabetical order by key. This option takes precedence over

+
+    If *sort_keys* is true (default: ``False``), the output of dictionaries

+

+        The return value of *object_pairs_hook* will be used instead of the

+        takes priority.

+        ``float(num_str)``. This can be used to use another datatype or parser
+        for JSON floats (e.g. :class:`decimal.Decimal`).

+        encoding of keys that are not str, int, long, float or None.  If
+        skipkeys is True, such items are simply skipped.
+
+        If ensure_ascii is true, the output is guaranteed to be str
+        objects with all incoming unicode characters escaped.  If
+        ensure_ascii is false, the output will be unicode object.
+
+        If check_circular is true, then lists, dicts, and custom encoded
+        objects will be checked for circular references during encoding to
+        prevent an infinite recursion (which would cause an OverflowError).
+        Otherwise, no such check takes place.
+
+        If allow_nan is true, then NaN, Infinity, and -Infinity will be
+        encoded as such.  This behavior is not JSON specification compliant,
+        but is consistent with most JavaScript based encoders and decoders.
+        Otherwise, it will be a ValueError to encode such floats.
+
+        If sort_keys is true, then the output of dictionaries will be
+        sorted by key; this is useful for regression tests to ensure
+        that JSON serializations can be compared on a day-to-day basis.
+
+        If indent is a string, then JSON array elements and object members
+        will be pretty-printed with a newline followed by that string repeated
+        for each level of nesting. ``None`` (the default) selects the most compact
+        representation without any newlines. For backwards compatibility with
+        versions of simplejson earlier than 2.1.0, an integer is also accepted
+        and is converted to a string with that many spaces.
+
+        If specified, separators should be an (item_separator, key_separator)
+        tuple.  The default is (', ', ': ') if *indent* is ``None`` and
+        (',', ': ') otherwise.  To get the most compact JSON representation,
+        you should specify (',', ':') to eliminate whitespace.
+
+        If specified, default is a function that gets called for objects
+        that can't otherwise be serialized.  It should return a JSON encodable
+        version of the object or raise a ``TypeError``.
+
+        If encoding is not None, then all input strings will be
+        transformed into unicode using that encoding prior to JSON-encoding.
+        The default is UTF-8.
+
+        If use_decimal is true (not the default), ``decimal.Decimal`` will
+        be supported directly by the encoder. For the inverse, decode JSON
+        with ``parse_float=decimal.Decimal``.
+
+        If namedtuple_as_object is true (the default), objects with
+        ``_asdict()`` methods will be encoded as JSON objects.
+
+        If tuple_as_array is true (the default), tuple (and subclasses) will
+        be encoded as JSON arrays.
+
+        If bigint_as_string is true (not the default), ints 2**53 and higher
+        or lower than -2**53 will be encoded as strings. This is to avoid the
+        rounding that happens in Javascript otherwise.
+
+        If int_as_string_bitcount is a positive number (n), then int of size
+        greater than or equal to 2**n or lower than or equal to -2**n will be
+        encoded as strings.
+
+        If specified, item_sort_key is a callable used to sort the items in
+        each dictionary. This is useful if you want to sort items other than
+        in alphabetical order by key.
+
+        If for_json is true (not the default), objects with a ``for_json()``
+        method will use the return value of that method for encoding as JSON
+        instead of the object.
+
+        If *ignore_nan* is true (default: ``False``), then out of range
+        :class:`float` values (``nan``, ``inf``, ``-inf``) will be serialized
+        as ``null`` in compliance with the ECMA-262 specification. If true,

+
+Six is a Python 2 and 3 compatibility library.  It provides utility functions
+for smoothing over the differences between the Python versions with the goal of
+writing Python code that is compatible on both Python versions.  See the
+documentation for more information on what is provided.
+
+Six supports every Python version since 2.5.  It is contained in only one Python
+file, so it can be easily copied into your project. (The copyright and license
+notice must be retained.)
+
+Online documentation is at http://pythonhosted.org/six/.
+
+Bugs can be reported to http://bitbucket.org/gutworth/six.  The code can also be
+found there.
+
+For questions about six or porting in general, email the python-porting mailing
+list: http://mail.python.org/mailman/listinfo/python-porting

+.. dialect:: drizzle
+    :name: Drizzle
+
+Drizzle is a variant of MySQL. Unlike MySQL, Drizzle's default storage engine
+is InnoDB (transactions, foreign-keys) rather than MyISAM. For more
+`Notable Differences <http://docs.drizzle.org/mysql_differences.html>`_, visit
+the `Drizzle Documentation <http://docs.drizzle.org/index.html>`_.
+
+The SQLAlchemy Drizzle dialect leans heavily on the MySQL dialect, so much of
+the :doc:`SQLAlchemy MySQL <mysql>` documentation is also relevant.

+.. dialect:: firebird
+    :name: Firebird
+
+Firebird Dialects
+-----------------
+
+Firebird offers two distinct dialects_ (not to be confused with a
+SQLAlchemy ``Dialect``):
+
+dialect 1
+  This is the old syntax and behaviour, inherited from Interbase pre-6.0.
+
+dialect 3
+  This is the newer and supported syntax, introduced in Interbase 6.0.
+
+The SQLAlchemy Firebird dialect detects these versions and
+adjusts its representation of SQL accordingly.  However,
+support for dialect 1 is not well tested and probably has
+incompatibilities.
+
+Locking Behavior
+----------------
+
+Firebird locks tables aggressively.  For this reason, a DROP TABLE may
+hang until other transactions are released.  SQLAlchemy does its best
+to release transactions as quickly as possible.  The most common cause
+of hanging transactions is a non-fully consumed result set, i.e.::
+
+    result = engine.execute("select * from table")
+    row = result.fetchone()
+    return
+
+Where above, the ``ResultProxy`` has not been fully consumed.  The
+connection will be returned to the pool and the transactional state
+rolled back once the Python garbage collector reclaims the objects
+which hold onto the connection, which often occurs asynchronously.
+The above use case can be alleviated by calling ``first()`` on the
+``ResultProxy`` which will fetch the first row and immediately close
+all remaining cursor/connection resources.
+
+RETURNING support
+-----------------
+
+Firebird 2.0 supports returning a result set from inserts, and 2.1
+extends that to deletes and updates. This is generically exposed by
+the SQLAlchemy ``returning()`` method, such as::
+
+    # INSERT..RETURNING
+    result = table.insert().returning(table.c.col1, table.c.col2).\\
+                   values(name='foo')
+    print result.fetchall()
+
+    # UPDATE..RETURNING
+    raises = empl.update().returning(empl.c.id, empl.c.salary).\\
+                  where(empl.c.sales>100).\\
+                  values(dict(salary=empl.c.salary * 1.1))
+    print raises.fetchall()
+

+.. dialect:: firebird+fdb
+    :name: fdb
+    :dbapi: pyodbc
+    :connectstring: firebird+fdb://user:password@host:port/path/to/db\
+[?key=value&key=value...]
+    :url: http://pypi.python.org/pypi/fdb/
+
+    fdb is a kinterbasdb compatible DBAPI for Firebird.
+
+    .. versionadded:: 0.8 - Support for the fdb Firebird driver.
+
+    .. versionchanged:: 0.9 - The fdb dialect is now the default dialect
+       under the ``firebird://`` URL space, as ``fdb`` is now the official
+       Python driver for Firebird.
+
+Arguments
+----------
+
+The ``fdb`` dialect is based on the
+:mod:`sqlalchemy.dialects.firebird.kinterbasdb` dialect, however does not
+accept every argument that Kinterbasdb does.
+
+* ``enable_rowcount`` - True by default, setting this to False disables
+  the usage of "cursor.rowcount" with the
+  Kinterbasdb dialect, which SQLAlchemy ordinarily calls upon automatically
+  after any UPDATE or DELETE statement.   When disabled, SQLAlchemy's
+  ResultProxy will return -1 for result.rowcount.   The rationale here is
+  that Kinterbasdb requires a second round trip to the database when
+  .rowcount is called -  since SQLA's resultproxy automatically closes
+  the cursor after a non-result-returning statement, rowcount must be
+  called, if at all, before the result object is returned.   Additionally,
+  cursor.rowcount may not return correct results with older versions
+  of Firebird, and setting this flag to False will also cause the
+  SQLAlchemy ORM to ignore its usage. The behavior can also be controlled on a
+  per-execution basis using the ``enable_rowcount`` option with
+  :meth:`.Connection.execution_options`::
+
+      conn = engine.connect().execution_options(enable_rowcount=True)
+      r = conn.execute(stmt)
+      print r.rowcount
+
+* ``retaining`` - False by default.   Setting this to True will pass the
+  ``retaining=True`` keyword argument to the ``.commit()`` and ``.rollback()``
+  methods of the DBAPI connection, which can improve performance in some
+  situations, but apparently with significant caveats.
+  Please read the fdb and/or kinterbasdb DBAPI documentation in order to
+  understand the implications of this flag.
+
+  .. versionadded:: 0.8.2 - ``retaining`` keyword argument specifying
+     transaction retaining behavior - in 0.8 it defaults to ``True``
+     for backwards compatibility.
+
+  .. versionchanged:: 0.9.0 - the ``retaining`` flag defaults to ``False``.
+     In 0.8 it defaulted to ``True``.
+
+  .. seealso::
+
+    http://pythonhosted.org/fdb/usage-guide.html#retaining-transactions

+
+
+Auto Increment Behavior
+-----------------------
+
+SQL Server provides so-called "auto incrementing" behavior using the
+``IDENTITY`` construct, which can be placed on an integer primary key.
+SQLAlchemy considers ``IDENTITY`` within its default "autoincrement" behavior,
+described at :paramref:`.Column.autoincrement`; this means
+that by default, the first integer primary key column in a :class:`.Table`
+will be considered to be the identity column and will generate DDL as such::
+
+    from sqlalchemy import Table, MetaData, Column, Integer
+
+    m = MetaData()
+    t = Table('t', m,
+            Column('id', Integer, primary_key=True),
+            Column('x', Integer))
+    m.create_all(engine)
+
+The above example will generate DDL as:
+
+.. sourcecode:: sql
+
+    CREATE TABLE t (
+        id INTEGER NOT NULL IDENTITY(1,1),
+        x INTEGER NULL,
+        PRIMARY KEY (id)
+    )
+
+For the case where this default generation of ``IDENTITY`` is not desired,
+specify ``autoincrement=False`` on all integer primary key columns::
+
+    m = MetaData()
+    t = Table('t', m,
+            Column('id', Integer, primary_key=True, autoincrement=False),
+            Column('x', Integer))
+    m.create_all(engine)
+
+.. note::
+
+    An INSERT statement which refers to an explicit value for such
+    a column is prohibited by SQL Server, however SQLAlchemy will detect this
+    and modify the ``IDENTITY_INSERT`` flag accordingly at statement execution
+    time.  As this is not a high performing process, care should be taken to
+    set the ``autoincrement`` flag appropriately for columns that will not
+    actually require IDENTITY behavior.
+
+Controlling "Start" and "Increment"
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Specific control over the parameters of the ``IDENTITY`` value is supported
+using the :class:`.schema.Sequence` object.  While this object normally
+represents an explicit "sequence" for supporting backends, on SQL Server it is
+re-purposed to specify behavior regarding the identity column, including
+support of the "start" and "increment" values::
+
+    from sqlalchemy import Table, Integer, Sequence, Column
+
+    Table('test', metadata,
+           Column('id', Integer,
+                  Sequence('blah', start=100, increment=10),
+                  primary_key=True),
+           Column('name', String(20))
+         ).create(some_engine)
+
+would yield:
+
+.. sourcecode:: sql
+
+   CREATE TABLE test (
+     id INTEGER NOT NULL IDENTITY(100,10) PRIMARY KEY,
+     name VARCHAR(20) NULL,
+     )
+
+Note that the ``start`` and ``increment`` values for sequences are
+optional and will default to 1,1.
+
+INSERT behavior
+^^^^^^^^^^^^^^^^
+
+Handling of the ``IDENTITY`` column at INSERT time involves two key
+techniques. The most common is being able to fetch the "last inserted value"
+for a given ``IDENTITY`` column, a process which SQLAlchemy performs
+implicitly in many cases, most importantly within the ORM.
+
+The process for fetching this value has several variants:
+
+* In the vast majority of cases, RETURNING is used in conjunction with INSERT
+  statements on SQL Server in order to get newly generated primary key values:
+
+  .. sourcecode:: sql
+
+    INSERT INTO t (x) OUTPUT inserted.id VALUES (?)
+
+* When RETURNING is not available or has been disabled via
+  ``implicit_returning=False``, either the ``scope_identity()`` function or
+  the ``@@identity`` variable is used; behavior varies by backend:
+
+  * when using PyODBC, the phrase ``; select scope_identity()`` will be
+    appended to the end of the INSERT statement; a second result set will be
+    fetched in order to receive the value.  Given a table as::
+
+        t = Table('t', m, Column('id', Integer, primary_key=True),
+                Column('x', Integer),
+                implicit_returning=False)
+
+    an INSERT will look like:
+
+    .. sourcecode:: sql
+
+        INSERT INTO t (x) VALUES (?); select scope_identity()
+
+  * Other dialects such as pymssql will call upon
+    ``SELECT scope_identity() AS lastrowid`` subsequent to an INSERT
+    statement. If the flag ``use_scope_identity=False`` is passed to
+    :func:`.create_engine`, the statement ``SELECT @@identity AS lastrowid``
+    is used instead.
+
+A table that contains an ``IDENTITY`` column will prohibit an INSERT statement
+that refers to the identity column explicitly.  The SQLAlchemy dialect will
+detect when an INSERT construct, created using a core :func:`.insert`
+construct (not a plain string SQL), refers to the identity column, and
+in this case will emit ``SET IDENTITY_INSERT ON`` prior to the insert
+statement proceeding, and ``SET IDENTITY_INSERT OFF`` subsequent to the
+execution.  Given this example::
+
+    m = MetaData()
+    t = Table('t', m, Column('id', Integer, primary_key=True),
+                    Column('x', Integer))
+    m.create_all(engine)
+
+    engine.execute(t.insert(), {'id': 1, 'x':1}, {'id':2, 'x':2})
+
+The above column will be created with IDENTITY, however the INSERT statement
+we emit is specifying explicit values.  In the echo output we can see
+how SQLAlchemy handles this:
+
+.. sourcecode:: sql
+
+    CREATE TABLE t (
+        id INTEGER NOT NULL IDENTITY(1,1),
+        x INTEGER NULL,
+        PRIMARY KEY (id)
+    )
+
+    COMMIT
+    SET IDENTITY_INSERT t ON
+    INSERT INTO t (id, x) VALUES (?, ?)
+    ((1, 1), (2, 2))
+    SET IDENTITY_INSERT t OFF
+    COMMIT
+
+
+
+This
+is an auxilliary use case suitable for testing and bulk insert scenarios.
+
+
+Collation Support
+-----------------
+
+Character collations are supported by the base string types,
+specified by the string argument "collation"::
+
+    from sqlalchemy import VARCHAR
+    Column('login', VARCHAR(32, collation='Latin1_General_CI_AS'))
+
+When such a column is associated with a :class:`.Table`, the
+CREATE TABLE statement for this column will yield::
+
+    login VARCHAR(32) COLLATE Latin1_General_CI_AS NULL
+
+.. versionadded:: 0.8 Character collations are now part of the base string
+   types.
+
+LIMIT/OFFSET Support
+--------------------
+
+MSSQL has no support for the LIMIT or OFFSET keysowrds. LIMIT is
+supported directly through the ``TOP`` Transact SQL keyword::
+
+    select.limit
+
+will yield::
+
+    SELECT TOP n
+
+If using SQL Server 2005 or above, LIMIT with OFFSET
+support is available through the ``ROW_NUMBER OVER`` construct.
+For versions below 2005, LIMIT with OFFSET usage will fail.
+
+Nullability
+-----------
+MSSQL has support for three levels of column nullability. The default
+nullability allows nulls and is explicit in the CREATE TABLE
+construct::
+
+    name VARCHAR(20) NULL
+
+If ``nullable=None`` is specified then no specification is made. In
+other words the database's configured default is used. This will
+render::
+
+    name VARCHAR(20)
+
+If ``nullable`` is ``True`` or ``False`` then the column will be
+``NULL` or ``NOT NULL`` respectively.
+
+Date / Time Handling
+--------------------
+DATE and TIME are supported.   Bind parameters are converted
+to datetime.datetime() objects as required by most MSSQL drivers,
+and results are processed from strings if needed.
+The DATE and TIME types are not available for MSSQL 2005 and
+previous - if a server version below 2008 is detected, DDL
+for these types will be issued as DATETIME.
+
+.. _mssql_indexes:
+
+Clustered Index Support
+-----------------------
+
+The MSSQL dialect supports clustered indexes (and primary keys) via the
+``mssql_clustered`` option.  This option is available to :class:`.Index`,
+:class:`.UniqueConstraint`. and :class:`.PrimaryKeyConstraint`.
+
+To generate a clustered index::
+
+    Index("my_index", table.c.x, mssql_clustered=True)
+
+which renders the index as ``CREATE CLUSTERED INDEX my_index ON table (x)``.
+
+.. versionadded:: 0.8
+
+To generate a clustered primary key use::
+
+    Table('my_table', metadata,
+          Column('x', ...),
+          Column('y', ...),
+          PrimaryKeyConstraint("x", "y", mssql_clustered=True))
+
+which will render the table, for example, as::
+
+  CREATE TABLE my_table (x INTEGER NOT NULL, y INTEGER NOT NULL,
+                         PRIMARY KEY CLUSTERED (x, y))
+
+Similarly, we can generate a clustered unique constraint using::
+
+    Table('my_table', metadata,
+          Column('x', ...),
+          Column('y', ...),
+          PrimaryKeyConstraint("x"),
+          UniqueConstraint("y", mssql_clustered=True),
+          )
+
+  .. versionadded:: 0.9.2
+
+MSSQL-Specific Index Options
+-----------------------------
+
+In addition to clustering, the MSSQL dialect supports other special options
+for :class:`.Index`.
+
+INCLUDE
+^^^^^^^
+
+The ``mssql_include`` option renders INCLUDE(colname) for the given string
+names::
+
+    Index("my_index", table.c.x, mssql_include=['y'])
+
+would render the index as ``CREATE INDEX my_index ON table (x) INCLUDE (y)``
+
+.. versionadded:: 0.8
+
+Index ordering
+^^^^^^^^^^^^^^
+
+Index ordering is available via functional expressions, such as::
+
+    Index("my_index", table.c.x.desc())
+
+would render the index as ``CREATE INDEX my_index ON table (x DESC)``
+
+.. versionadded:: 0.8
+
+.. seealso::
+
+    :ref:`schema_indexes_functional`
+
+Compatibility Levels
+--------------------
+MSSQL supports the notion of setting compatibility levels at the
+database level. This allows, for instance, to run a database that
+is compatible with SQL2000 while running on a SQL2005 database
+server. ``server_version_info`` will always return the database
+server version information (in this case SQL2005) and not the
+compatibility level information. Because of this, if running under
+a backwards compatibility mode SQAlchemy may attempt to use T-SQL
+statements that are unable to be parsed by the database server.
+
+Triggers
+--------
+
+SQLAlchemy by default uses OUTPUT INSERTED to get at newly
+generated primary key values via IDENTITY columns or other
+server side defaults.   MS-SQL does not
+allow the usage of OUTPUT INSERTED on tables that have triggers.
+To disable the usage of OUTPUT INSERTED on a per-table basis,
+specify ``implicit_returning=False`` for each :class:`.Table`
+which has triggers::
+
+    Table('mytable', metadata,
+        Column('id', Integer, primary_key=True),
+        # ...,
+        implicit_returning=False
+    )
+
+Declarative form::
+
+    class MyClass(Base):
+        # ...
+        __table_args__ = {'implicit_returning':False}
+
+
+This option can also be specified engine-wide using the
+``implicit_returning=False`` argument on :func:`.create_engine`.
+
+Enabling Snapshot Isolation
+---------------------------
+
+Not necessarily specific to SQLAlchemy, SQL Server has a default transaction
+isolation mode that locks entire tables, and causes even mildly concurrent
+applications to have long held locks and frequent deadlocks.
+Enabling snapshot isolation for the database as a whole is recommended
+for modern levels of concurrency support.  This is accomplished via the
+following ALTER DATABASE commands executed at the SQL prompt::
+
+    ALTER DATABASE MyDatabase SET ALLOW_SNAPSHOT_ISOLATION ON
+
+    ALTER DATABASE MyDatabase SET READ_COMMITTED_SNAPSHOT ON
+
+Background on SQL Server snapshot isolation is available at
+http://msdn.microsoft.com/en-us/library/ms175095.aspx.
+

+
+Execution Modes
+---------------
+
+mxODBC features two styles of statement execution, using the
+``cursor.execute()`` and ``cursor.executedirect()`` methods (the second being
+an extension to the DBAPI specification). The former makes use of a particular
+API call specific to the SQL Server Native Client ODBC driver known
+SQLDescribeParam, while the latter does not.
+
+mxODBC apparently only makes repeated use of a single prepared statement
+when SQLDescribeParam is used. The advantage to prepared statement reuse is
+one of performance. The disadvantage is that SQLDescribeParam has a limited
+set of scenarios in which bind parameters are understood, including that they
+cannot be placed within the argument lists of function calls, anywhere outside
+the FROM, or even within subqueries within the FROM clause - making the usage
+of bind parameters within SELECT statements impossible for all but the most
+simplistic statements.
+
+For this reason, the mxODBC dialect uses the "native" mode by default only for
+INSERT, UPDATE, and DELETE statements, and uses the escaped string mode for
+all other statements.
+
+This behavior can be controlled via
+:meth:`~sqlalchemy.sql.expression.Executable.execution_options` using the
+``native_odbc_execute`` flag with a value of ``True`` or ``False``, where a
+value of ``True`` will unconditionally use native bind parameters and a value
+of ``False`` will unconditionally use string-escaped parameters.

+
+    DRIVER={SQL Server};Server=host,123;Database=db;UID=user;PWD=pass
+
+* ``mssql+pyodbc://user:pass@host/db?port=123`` - connects using a connection
+  string that includes the port
+  information as a separate ``port`` keyword. This will create the
+  following connection string::
+
+    DRIVER={SQL Server};Server=host;Database=db;UID=user;PWD=pass;port=123
+
+* ``mssql+pyodbc://user:pass@host/db?driver=MyDriver`` - connects using a
+  connection string that includes a custom ODBC driver name.  This will create
+  the following connection string::
+
+    DRIVER={MyDriver};Server=host;Database=db;UID=user;PWD=pass
+
+If you require a connection string that is outside the options
+presented above, use the ``odbc_connect`` keyword to pass in a
+urlencoded connection string. What gets passed in will be urldecoded
+and passed directly.
+
+For example::
+
+    mssql+pyodbc:///?odbc_connect=dsn%3Dmydsn%3BDatabase%3Ddb
+
+would create the following connection string::
+
+    dsn=mydsn;Database=db
+
+Encoding your connection string can be easily accomplished through
+the python shell. For example::
+
+    >>> import urllib
+    >>> urllib.quote_plus('dsn=mydsn;Database=db')
+    'dsn%3Dmydsn%3BDatabase%3Ddb'
+
+Unicode Binds
+-------------
+
+The current state of PyODBC on a unix backend with FreeTDS and/or
+EasySoft is poor regarding unicode; different OS platforms and versions of
+UnixODBC versus IODBC versus FreeTDS/EasySoft versus PyODBC itself
+dramatically alter how strings are received.  The PyODBC dialect attempts to
+use all the information it knows to determine whether or not a Python unicode
+literal can be passed directly to the PyODBC driver or not; while SQLAlchemy
+can encode these to bytestrings first, some users have reported that PyODBC
+mis-handles bytestrings for certain encodings and requires a Python unicode
+object, while the author has observed widespread cases where a Python unicode
+is completely misinterpreted by PyODBC, particularly when dealing with
+the information schema tables used in table reflection, and the value
+must first be encoded to a bytestring.
+
+It is for this reason that whether or not unicode literals for bound
+parameters be sent to PyODBC can be controlled using the
+``supports_unicode_binds`` parameter to ``create_engine()``.  When
+left at its default of ``None``, the PyODBC dialect will use its
+best guess as to whether or not the driver deals with unicode literals
+well.  When ``False``, unicode literals will be encoded first, and when
+``True`` unicode literals will be passed straight through.  This is an interim
+flag that hopefully should not be needed when the unicode situation stabilizes
+for unix + PyODBC.

+    :name: MySQL
+
+Supported Versions and Features
+-------------------------------
+
+SQLAlchemy supports MySQL starting with version 4.1 through modern releases.
+However, no heroic measures are taken to work around major missing
+SQL features - if your server version does not support sub-selects, for
+example, they won't work in SQLAlchemy either.
+
+See the official MySQL documentation for detailed information about features
+supported in any given server release.
+
+.. _mysql_connection_timeouts:
+
+Connection Timeouts
+-------------------
+
+MySQL features an automatic connection close behavior, for connections that
+have been idle for eight hours or more.   To circumvent having this issue, use
+the ``pool_recycle`` option which controls the maximum age of any connection::
+
+    engine = create_engine('mysql+mysqldb://...', pool_recycle=3600)
+
+.. _mysql_storage_engines:
+
+CREATE TABLE arguments including Storage Engines
+------------------------------------------------
+
+MySQL's CREATE TABLE syntax includes a wide array of special options,
+including ``ENGINE``, ``CHARSET``, ``MAX_ROWS``, ``ROW_FORMAT``,
+``INSERT_METHOD``, and many more.
+To accommodate the rendering of these arguments, specify the form
+``mysql_argument_name="value"``.  For example, to specify a table with
+``ENGINE`` of ``InnoDB``, ``CHARSET`` of ``utf8``, and ``KEY_BLOCK_SIZE``
+of ``1024``::
+
+  Table('mytable', metadata,
+        Column('data', String(32)),
+        mysql_engine='InnoDB',
+        mysql_charset='utf8',
+        mysql_key_block_size="1024"
+       )
+
+The MySQL dialect will normally transfer any keyword specified as
+``mysql_keyword_name`` to be rendered as ``KEYWORD_NAME`` in the
+``CREATE TABLE`` statement.  A handful of these names will render with a space
+instead of an underscore; to support this, the MySQL dialect has awareness of
+these particular names, which include ``DATA DIRECTORY``
+(e.g. ``mysql_data_directory``), ``CHARACTER SET`` (e.g.
+``mysql_character_set``) and ``INDEX DIRECTORY`` (e.g.
+``mysql_index_directory``).
+
+The most common argument is ``mysql_engine``, which refers to the storage
+engine for the table.  Historically, MySQL server installations would default
+to ``MyISAM`` for this value, although newer versions may be defaulting
+to ``InnoDB``.  The ``InnoDB`` engine is typically preferred for its support
+of transactions and foreign keys.
+
+A :class:`.Table` that is created in a MySQL database with a storage engine
+of ``MyISAM`` will be essentially non-transactional, meaning any
+INSERT/UPDATE/DELETE statement referring to this table will be invoked as
+autocommit.   It also will have no support for foreign key constraints; while
+the ``CREATE TABLE`` statement accepts foreign key options, when using the
+``MyISAM`` storage engine these arguments are discarded.  Reflecting such a
+table will also produce no foreign key constraint information.
+
+For fully atomic transactions as well as support for foreign key
+constraints, all participating ``CREATE TABLE`` statements must specify a
+transactional engine, which in the vast majority of cases is ``InnoDB``.
+
+.. seealso::
+
+    `The InnoDB Storage Engine
+    <http://dev.mysql.com/doc/refman/5.0/en/innodb-storage-engine.html>`_ -
+    on the MySQL website.
+
+Case Sensitivity and Table Reflection
+-------------------------------------
+
+MySQL has inconsistent support for case-sensitive identifier
+names, basing support on specific details of the underlying
+operating system. However, it has been observed that no matter
+what case sensitivity behavior is present, the names of tables in
+foreign key declarations are *always* received from the database
+as all-lower case, making it impossible to accurately reflect a
+schema where inter-related tables use mixed-case identifier names.
+
+Therefore it is strongly advised that table names be declared as
+all lower case both within SQLAlchemy as well as on the MySQL
+database itself, especially if database reflection features are
+to be used.
+
+Transaction Isolation Level
+---------------------------
+
+:func:`.create_engine` accepts an ``isolation_level``
+parameter which results in the command ``SET SESSION
+TRANSACTION ISOLATION LEVEL <level>`` being invoked for
+every new connection. Valid values for this parameter are
+``READ COMMITTED``, ``READ UNCOMMITTED``,
+``REPEATABLE READ``, and ``SERIALIZABLE``::
+
+    engine = create_engine(
+                    "mysql://scott:tiger@localhost/test",
+                    isolation_level="READ UNCOMMITTED"
+                )
+
+.. versionadded:: 0.7.6
+
+AUTO_INCREMENT Behavior
+-----------------------
+
+When creating tables, SQLAlchemy will automatically set ``AUTO_INCREMENT`` on
+the first :class:`.Integer` primary key column which is not marked as a
+foreign key::
+
+  >>> t = Table('mytable', metadata,
+  ...   Column('mytable_id', Integer, primary_key=True)
+  ... )
+  >>> t.create()
+  CREATE TABLE mytable (
+          id INTEGER NOT NULL AUTO_INCREMENT,
+          PRIMARY KEY (id)
+  )
+
+You can disable this behavior by passing ``False`` to the
+:paramref:`~.Column.autoincrement` argument of :class:`.Column`.  This flag
+can also be used to enable auto-increment on a secondary column in a
+multi-column key for some storage engines::
+
+  Table('mytable', metadata,
+        Column('gid', Integer, primary_key=True, autoincrement=False),
+        Column('id', Integer, primary_key=True)
+       )
+
+Ansi Quoting Style
+------------------
+
+MySQL features two varieties of identifier "quoting style", one using
+backticks and the other using quotes, e.g. ```some_identifier```  vs.
+``"some_identifier"``.   All MySQL dialects detect which version
+is in use by checking the value of ``sql_mode`` when a connection is first
+established with a particular :class:`.Engine`.  This quoting style comes
+into play when rendering table and column names as well as when reflecting
+existing database structures.  The detection is entirely automatic and
+no special configuration is needed to use either quoting style.
+
+.. versionchanged:: 0.6 detection of ANSI quoting style is entirely automatic,
+   there's no longer any end-user ``create_engine()`` options in this regard.
+
+MySQL SQL Extensions
+--------------------
+
+Many of the MySQL SQL extensions are handled through SQLAlchemy's generic
+function and operator support::
+
+  table.select(table.c.password==func.md5('plaintext'))
+  table.select(table.c.username.op('regexp')('^[a-d]'))
+
+And of course any valid MySQL statement can be executed as a string as well.
+
+Some limited direct support for MySQL extensions to SQL is currently
+available.
+
+* SELECT pragma::
+
+    select(..., prefixes=['HIGH_PRIORITY', 'SQL_SMALL_RESULT'])
+
+* UPDATE with LIMIT::
+
+    update(..., mysql_limit=10)
+
+rowcount Support
+----------------
+
+SQLAlchemy standardizes the DBAPI ``cursor.rowcount`` attribute to be the
+usual definition of "number of rows matched by an UPDATE or DELETE" statement.
+This is in contradiction to the default setting on most MySQL DBAPI drivers,
+which is "number of rows actually modified/deleted".  For this reason, the
+SQLAlchemy MySQL dialects always set the ``constants.CLIENT.FOUND_ROWS`` flag,
+or whatever is equivalent for the DBAPI in use, on connect, unless the flag
+value is overridden using DBAPI-specific options
+(such as ``client_flag`` for the MySQL-Python driver, ``found_rows`` for the
+OurSQL driver).
+
+See also:
+
+:attr:`.ResultProxy.rowcount`
+
+
+CAST Support
+------------
+
+MySQL documents the CAST operator as available in version 4.0.2.  When using
+the SQLAlchemy :func:`.cast` function, SQLAlchemy
+will not render the CAST token on MySQL before this version, based on server
+version detection, instead rendering the internal expression directly.
+
+CAST may still not be desirable on an early MySQL version post-4.0.2, as it
+didn't add all datatype support until 4.1.1.   If your application falls into
+this narrow area, the behavior of CAST can be controlled using the
+:ref:`sqlalchemy.ext.compiler_toplevel` system, as per the recipe below::
+
+    from sqlalchemy.sql.expression import Cast

+
+
+.. _mysql_indexes:
+
+MySQL Specific Index Options
+----------------------------
+
+MySQL-specific extensions to the :class:`.Index` construct are available.
+
+Index Length
+~~~~~~~~~~~~~
+
+MySQL provides an option to create index entries with a certain length, where
+"length" refers to the number of characters or bytes in each value which will
+become part of the index. SQLAlchemy provides this feature via the
+``mysql_length`` parameter::
+
+    Index('my_index', my_table.c.data, mysql_length=10)
+
+    Index('a_b_idx', my_table.c.a, my_table.c.b, mysql_length={'a': 4,
+                                                               'b': 9})
+
+Prefix lengths are given in characters for nonbinary string types and in bytes
+for binary string types. The value passed to the keyword argument *must* be
+either an integer (and, thus, specify the same prefix length value for all
+columns of the index) or a dict in which keys are column names and values are
+prefix length values for corresponding columns. MySQL only allows a length for
+a column of an index if it is for a CHAR, VARCHAR, TEXT, BINARY, VARBINARY and
+BLOB.
+
+.. versionadded:: 0.8.2 ``mysql_length`` may now be specified as a dictionary
+   for use with composite indexes.
+
+Index Types
+~~~~~~~~~~~~~
+
+Some MySQL storage engines permit you to specify an index type when creating
+an index or primary key constraint. SQLAlchemy provides this feature via the
+``mysql_using`` parameter on :class:`.Index`::
+
+    Index('my_index', my_table.c.data, mysql_using='hash')
+
+As well as the ``mysql_using`` parameter on :class:`.PrimaryKeyConstraint`::
+
+    PrimaryKeyConstraint("data", mysql_using='hash')
+
+The value passed to the keyword argument will be simply passed through to the
+underlying CREATE INDEX or PRIMARY KEY clause, so it *must* be a valid index
+type for your MySQL storage engine.

+http://dev.mysql.com/doc/refman/5.0/en/create-index.html

+
+.. _mysql_foreign_keys:
+
+MySQL Foreign Keys
+------------------
+
+MySQL's behavior regarding foreign keys has some important caveats.
+
+Foreign Key Arguments to Avoid
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+MySQL does not support the foreign key arguments "DEFERRABLE", "INITIALLY",
+or "MATCH".  Using the ``deferrable`` or ``initially`` keyword argument with
+:class:`.ForeignKeyConstraint` or :class:`.ForeignKey` will have the effect of
+these keywords being rendered in a DDL expression, which will then raise an
+error on MySQL.  In order to use these keywords on a foreign key while having
+them ignored on a MySQL backend, use a custom compile rule::
+
+    from sqlalchemy.ext.compiler import compiles
+    from sqlalchemy.schema import ForeignKeyConstraint
+
+    @compiles(ForeignKeyConstraint, "mysql")
+    def process(element, compiler, **kw):
+        element.deferrable = element.initially = None
+        return compiler.visit_foreign_key_constraint(element, **kw)
+
+.. versionchanged:: 0.9.0 - the MySQL backend no longer silently ignores
+   the ``deferrable`` or ``initially`` keyword arguments of
+   :class:`.ForeignKeyConstraint` and :class:`.ForeignKey`.
+
+The "MATCH" keyword is in fact more insidious, and is explicitly disallowed
+by SQLAlchemy in conjunction with the MySQL backend.  This argument is
+silently ignored by MySQL, but in addition has the effect of ON UPDATE and ON
+DELETE options also being ignored by the backend.   Therefore MATCH should
+never be used with the MySQL backend; as is the case with DEFERRABLE and
+INITIALLY, custom compilation rules can be used to correct a MySQL
+ForeignKeyConstraint at DDL definition time.
+
+.. versionadded:: 0.9.0 - the MySQL backend will raise a
+   :class:`.CompileError` when the ``match`` keyword is used with
+   :class:`.ForeignKeyConstraint` or :class:`.ForeignKey`.
+
+Reflection of Foreign Key Constraints
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Not all MySQL storage engines support foreign keys.  When using the
+very common ``MyISAM`` MySQL storage engine, the information loaded by table
+reflection will not include foreign keys.  For these tables, you may supply a
+:class:`~sqlalchemy.ForeignKeyConstraint` at reflection time::
+
+  Table('mytable', metadata,
+        ForeignKeyConstraint(['other_id'], ['othertable.other_id']),
+        autoload=True
+       )
+
+.. seealso::

+
+
+Unicode
+-------
+
+MySQLdb requires a "charset" parameter to be passed in order for it
+to handle non-ASCII characters correctly.   When this parameter is passed,
+MySQLdb will also implicitly set the "use_unicode" flag to true, which means
+that it will return Python unicode objects instead of bytestrings.
+However, SQLAlchemy's decode process, when C extensions are enabled,
+is orders of magnitude faster than that of MySQLdb as it does not call into
+Python functions to do so.  Therefore, the **recommended URL to use for
+unicode** will include both charset and use_unicode=0::
+
+    create_engine("mysql+mysqldb://user:pass@host/dbname?charset=utf8&use_unicode=0")
+
+As of this writing, MySQLdb only runs on Python 2.   It is not known how
+MySQLdb behaves on Python 3 as far as unicode decoding.
+
+
+Known Issues
+-------------
+
+MySQL-python version 1.2.2 has a serious memory leak related
+to unicode conversion, a feature which is disabled via ``use_unicode=0``.
+It is strongly advised to use the latest version of MySQL-Python.

+Unicode
+-------
+
+oursql defaults to using ``utf8`` as the connection charset, but other
+encodings may be used instead. Like the MySQL-Python driver, unicode support
+can be completely disabled::
+
+  # oursql sets the connection charset to utf8 automatically; all strings come
+  # back as utf8 str
+  create_engine('mysql+oursql:///mydb?use_unicode=0')
+
+To not automatically use ``utf8`` and instead use whatever the connection
+defaults to, there is a separate parameter::
+
+  # use the default connection charset; all strings come back as unicode
+  create_engine('mysql+oursql:///mydb?default_charset=1')
+
+  # use latin1 as the connection charset; all strings come back as unicode
+  create_engine('mysql+oursql:///mydb?charset=latin1')

+.. dialect:: oracle
+    :name: Oracle
+
+    Oracle version 8 through current (11g at the time of this writing) are
+    supported.
+
+Connect Arguments
+-----------------
+
+The dialect supports several :func:`~sqlalchemy.create_engine()` arguments
+which affect the behavior of the dialect regardless of driver in use.
+
+* ``use_ansi`` - Use ANSI JOIN constructs (see the section on Oracle 8).
+  Defaults to ``True``.  If ``False``, Oracle-8 compatible constructs are used
+  for joins.
+
+* ``optimize_limits`` - defaults to ``False``. see the section on
+  LIMIT/OFFSET.
+
+* ``use_binds_for_limits`` - defaults to ``True``.  see the section on
+  LIMIT/OFFSET.
+
+Auto Increment Behavior
+-----------------------
+
+SQLAlchemy Table objects which include integer primary keys are usually
+assumed to have "autoincrementing" behavior, meaning they can generate their
+own primary key values upon INSERT.  Since Oracle has no "autoincrement"
+feature, SQLAlchemy relies upon sequences to produce these values.   With the
+Oracle dialect, *a sequence must always be explicitly specified to enable
+autoincrement*.  This is divergent with the majority of documentation
+examples which assume the usage of an autoincrement-capable database.   To
+specify sequences, use the sqlalchemy.schema.Sequence object which is passed
+to a Column construct::
+
+  t = Table('mytable', metadata,
+        Column('id', Integer, Sequence('id_seq'), primary_key=True),
+        Column(...), ...
+  )
+
+This step is also required when using table reflection, i.e. autoload=True::
+
+  t = Table('mytable', metadata,
+        Column('id', Integer, Sequence('id_seq'), primary_key=True),
+        autoload=True
+  )
+
+Identifier Casing
+-----------------
+
+In Oracle, the data dictionary represents all case insensitive identifier
+names using UPPERCASE text.   SQLAlchemy on the other hand considers an
+all-lower case identifier name to be case insensitive.   The Oracle dialect
+converts all case insensitive identifiers to and from those two formats during
+schema level communication, such as reflection of tables and indexes.   Using
+an UPPERCASE name on the SQLAlchemy side indicates a case sensitive
+identifier, and SQLAlchemy will quote the name - this will cause mismatches
+against data dictionary data received from Oracle, so unless identifier names
+have been truly created as case sensitive (i.e. using quoted names), all
+lowercase names should be used on the SQLAlchemy side.
+
+
+LIMIT/OFFSET Support
+--------------------
+
+Oracle has no support for the LIMIT or OFFSET keywords.  SQLAlchemy uses
+a wrapped subquery approach in conjunction with ROWNUM.  The exact methodology
+is taken from
+http://www.oracle.com/technology/oramag/oracle/06-sep/o56asktom.html .
+
+There are two options which affect its behavior:
+
+* the "FIRST ROWS()" optimization keyword is not used by default.  To enable
+  the usage of this optimization directive, specify ``optimize_limits=True``
+  to :func:`.create_engine`.
+* the values passed for the limit/offset are sent as bound parameters.   Some
+  users have observed that Oracle produces a poor query plan when the values
+  are sent as binds and not rendered literally.   To render the limit/offset
+  values literally within the SQL statement, specify
+  ``use_binds_for_limits=False`` to :func:`.create_engine`.
+
+Some users have reported better performance when the entirely different
+approach of a window query is used, i.e. ROW_NUMBER() OVER (ORDER BY), to
+provide LIMIT/OFFSET (note that the majority of users don't observe this).
+To suit this case the method used for LIMIT/OFFSET can be replaced entirely.
+See the recipe at
+http://www.sqlalchemy.org/trac/wiki/UsageRecipes/WindowFunctionsByDefault
+which installs a select compiler that overrides the generation of limit/offset
+with a window function.
+
+.. _oracle_returning:
+
+RETURNING Support
+-----------------
+
+The Oracle database supports a limited form of RETURNING, in order to retrieve
+result sets of matched rows from INSERT, UPDATE and DELETE statements.
+Oracle's RETURNING..INTO syntax only supports one row being returned, as it
+relies upon OUT parameters in order to function.  In addition, supported
+DBAPIs have further limitations (see :ref:`cx_oracle_returning`).
+
+SQLAlchemy's "implicit returning" feature, which employs RETURNING within an
+INSERT and sometimes an UPDATE statement in order to fetch newly generated
+primary key values and other SQL defaults and expressions, is normally enabled
+on the Oracle backend.  By default, "implicit returning" typically only
+fetches the value of a single ``nextval(some_seq)`` expression embedded into
+an INSERT in order to increment a sequence within an INSERT statement and get
+the value back at the same time. To disable this feature across the board,
+specify ``implicit_returning=False`` to :func:`.create_engine`::
+
+    engine = create_engine("oracle://scott:tiger@dsn",
+                           implicit_returning=False)
+
+Implicit returning can also be disabled on a table-by-table basis as a table
+option::
+
+    # Core Table
+    my_table = Table("my_table", metadata, ..., implicit_returning=False)
+
+
+    # declarative
+    class MyClass(Base):
+        __tablename__ = 'my_table'
+        __table_args__ = {"implicit_returning": False}
+
+.. seealso::
+
+    :ref:`cx_oracle_returning` - additional cx_oracle-specific restrictions on
+    implicit returning.
+
+ON UPDATE CASCADE
+-----------------
+
+Oracle doesn't have native ON UPDATE CASCADE functionality.  A trigger based
+solution is available at
+http://asktom.oracle.com/tkyte/update_cascade/index.html .
+
+When using the SQLAlchemy ORM, the ORM has limited ability to manually issue
+cascading updates - specify ForeignKey objects using the
+"deferrable=True, initially='deferred'" keyword arguments,
+and specify "passive_updates=False" on each relationship().
+
+Oracle 8 Compatibility
+----------------------
+
+When Oracle 8 is detected, the dialect internally configures itself to the
+following behaviors:
+
+* the use_ansi flag is set to False.  This has the effect of converting all
+  JOIN phrases into the WHERE clause, and in the case of LEFT OUTER JOIN
+  makes use of Oracle's (+) operator.
+
+* the NVARCHAR2 and NCLOB datatypes are no longer generated as DDL when
+  the :class:`~sqlalchemy.types.Unicode` is used - VARCHAR2 and CLOB are
+  issued instead.   This because these types don't seem to work correctly on
+  Oracle 8 even though they are available.  The
+  :class:`~sqlalchemy.types.NVARCHAR` and
+  :class:`~sqlalchemy.dialects.oracle.NCLOB` types will always generate
+  NVARCHAR2 and NCLOB.
+
+* the "native unicode" mode is disabled when using cx_oracle, i.e. SQLAlchemy
+  encodes all Python unicode objects to "string" before passing in as bind
+  parameters.
+
+Synonym/DBLINK Reflection
+-------------------------
+
+When using reflection with Table objects, the dialect can optionally search
+for tables indicated by synonyms, either in local or remote schemas or
+accessed over DBLINK, by passing the flag ``oracle_resolve_synonyms=True`` as
+a keyword argument to the :class:`.Table` construct::
+
+    some_table = Table('some_table', autoload=True,
+                                autoload_with=some_engine,
+                                oracle_resolve_synonyms=True)
+
+When this flag is set, the given name (such as ``some_table`` above) will
+be searched not just in the ``ALL_TABLES`` view, but also within the
+``ALL_SYNONYMS`` view to see if this name is actually a synonym to another
+name.  If the synonym is located and refers to a DBLINK, the oracle dialect
+knows how to locate the table's information using DBLINK syntax(e.g.
+``@dblink``).
+
+``oracle_resolve_synonyms`` is accepted wherever reflection arguments are
+accepted, including methods such as :meth:`.MetaData.reflect` and
+:meth:`.Inspector.get_columns`.
+
+If synonyms are not in use, this flag should be left disabled.
+
+DateTime Compatibility
+----------------------
+
+Oracle has no datatype known as ``DATETIME``, it instead has only ``DATE``,
+which can actually store a date and time value.  For this reason, the Oracle
+dialect provides a type :class:`.oracle.DATE` which is a subclass of
+:class:`.DateTime`.   This type has no special behavior, and is only
+present as a "marker" for this type; additionally, when a database column
+is reflected and the type is reported as ``DATE``, the time-supporting
+:class:`.oracle.DATE` type is used.
+
+.. versionchanged:: 0.9.4 Added :class:`.oracle.DATE` to subclass
+   :class:`.DateTime`.  This is a change as previous versions
+   would reflect a ``DATE`` column as :class:`.types.DATE`, which subclasses
+   :class:`.Date`.   The only significance here is for schemes that are
+   examining the type of column for use in special Python translations or
+   for migrating schemas to other database backends.

+
+Additional Connect Arguments
+----------------------------
+
+When connecting with ``dbname`` present, the host, port, and dbname tokens are
+converted to a TNS name using
+the cx_oracle ``makedsn()`` function.  Otherwise, the host token is taken
+directly as a TNS name.
+
+Additional arguments which may be specified either as query string arguments
+on the URL, or as keyword arguments to :func:`.create_engine()` are:
+
+* ``allow_twophase`` - enable two-phase transactions.  Defaults to ``True``.
+
+* ``arraysize`` - set the cx_oracle.arraysize value on cursors, defaulted
+  to 50.  This setting is significant with cx_Oracle as the contents of LOB
+  objects are only readable within a "live" row (e.g. within a batch of
+  50 rows).
+
+* ``auto_convert_lobs`` - defaults to True; See :ref:`cx_oracle_lob`.
+
+* ``auto_setinputsizes`` - the cx_oracle.setinputsizes() call is issued for
+  all bind parameters.  This is required for LOB datatypes but can be
+  disabled to reduce overhead.  Defaults to ``True``.  Specific types
+  can be excluded from this process using the ``exclude_setinputsizes``
+  parameter.
+
+* ``coerce_to_unicode`` - see :ref:`cx_oracle_unicode` for detail.
+
+* ``coerce_to_decimal`` - see :ref:`cx_oracle_numeric` for detail.
+
+* ``exclude_setinputsizes`` - a tuple or list of string DBAPI type names to
+  be excluded from the "auto setinputsizes" feature.  The type names here
+  must match DBAPI types that are found in the "cx_Oracle" module namespace,
+  such as cx_Oracle.UNICODE, cx_Oracle.NCLOB, etc.   Defaults to
+  ``(STRING, UNICODE)``.
+
+  .. versionadded:: 0.8 specific DBAPI types can be excluded from the
+     auto_setinputsizes feature via the exclude_setinputsizes attribute.
+
+* ``mode`` - This is given the string value of SYSDBA or SYSOPER, or
+  alternatively an integer value.  This value is only available as a URL query
+  string argument.
+
+* ``threaded`` - enable multithreaded access to cx_oracle connections.
+  Defaults to ``True``.  Note that this is the opposite default of the
+  cx_Oracle DBAPI itself.
+
+.. _cx_oracle_unicode:
+
+Unicode
+-------
+
+The cx_Oracle DBAPI as of version 5 fully supports unicode, and has the
+ability to return string results as Python unicode objects natively.
+
+When used in Python 3, cx_Oracle returns all strings as Python unicode objects
+(that is, plain ``str`` in Python 3).  In Python 2, it will return as Python
+unicode those column values that are of type ``NVARCHAR`` or ``NCLOB``.  For
+column values that are of type ``VARCHAR`` or other non-unicode string types,
+it will return values as Python strings (e.g. bytestrings).
+
+The cx_Oracle SQLAlchemy dialect presents two different options for the use
+case of returning ``VARCHAR`` column values as Python unicode objects under
+Python 2:
+
+* the cx_Oracle DBAPI has the ability to coerce all string results to Python
+  unicode objects unconditionally using output type handlers.  This has
+  the advantage that the unicode conversion is global to all statements
+  at the cx_Oracle driver level, meaning it works with raw textual SQL
+  statements that have no typing information associated.  However, this system
+  has been observed to incur signfiicant performance overhead, not only
+  because it takes effect for all string values unconditionally, but also
+  because cx_Oracle under Python 2 seems to use a pure-Python function call in
+  order to do the decode operation, which under cPython can orders of
+  magnitude slower than doing it using C functions alone.
+
+* SQLAlchemy has unicode-decoding services built in, and when using
+  SQLAlchemy's C extensions, these functions do not use any Python function
+  calls and are very fast.  The disadvantage to this approach is that the
+  unicode conversion only takes effect for statements where the
+  :class:`.Unicode` type or :class:`.String` type with
+  ``convert_unicode=True`` is explicitly associated with the result column.
+  This is the case for any ORM or Core query or SQL expression as well as for
+  a :func:`.text` construct that specifies output column types, so in the vast
+  majority of cases this is not an issue. However, when sending a completely
+  raw string to :meth:`.Connection.execute`, this typing information isn't
+  present, unless the string is handled within a :func:`.text` construct that
+  adds typing information.
+
+As of version 0.9.2 of SQLAlchemy, the default approach is to use SQLAlchemy's
+typing system.  This keeps cx_Oracle's expensive Python 2 approach
+disabled unless the user explicitly wants it.  Under Python 3, SQLAlchemy
+detects that cx_Oracle is returning unicode objects natively and cx_Oracle's
+system is used.
+
+To re-enable cx_Oracle's output type handler under Python 2, the
+``coerce_to_unicode=True`` flag (new in 0.9.4) can be passed to
+:func:`.create_engine`::
+
+    engine = create_engine("oracle+cx_oracle://dsn", coerce_to_unicode=True)
+
+Alternatively, to run a pure string SQL statement and get ``VARCHAR`` results
+as Python unicode under Python 2 without using cx_Oracle's native handlers,
+the :func:`.text` feature can be used::
+
+    from sqlalchemy import text, Unicode
+    result = conn.execute(
+        text("select username from user").columns(username=Unicode))
+
+.. versionchanged:: 0.9.2 cx_Oracle's outputtypehandlers are no longer used
+   for unicode results of non-unicode datatypes in Python 2, after they were
+   identified as a major performance bottleneck.  SQLAlchemy's own unicode
+   facilities are used instead.
+
+.. versionadded:: 0.9.4 Added the ``coerce_to_unicode`` flag, to re-enable
+   cx_Oracle's outputtypehandler and revert to pre-0.9.2 behavior.
+
+.. _cx_oracle_returning:
+
+RETURNING Support
+-----------------
+
+The cx_oracle DBAPI supports a limited subset of Oracle's already limited
+RETURNING support.  Typically, results can only be guaranteed for at most one
+column being returned; this is the typical case when SQLAlchemy uses RETURNING
+to get just the value of a primary-key-associated sequence value.
+Additional column expressions will cause problems in a non-determinative way,
+due to cx_oracle's lack of support for the OCI_DATA_AT_EXEC API which is
+required for more complex RETURNING scenarios.
+
+For this reason, stability may be enhanced by disabling RETURNING support
+completely; SQLAlchemy otherwise will use RETURNING to fetch newly
+sequence-generated primary keys.  As illustrated in :ref:`oracle_returning`::
+
+    engine = create_engine("oracle://scott:tiger@dsn",
+                           implicit_returning=False)
+
+.. seealso::
+
+    http://docs.oracle.com/cd/B10501_01/appdev.920/a96584/oci05bnd.htm#420693
+    - OCI documentation for RETURNING
+
+    http://sourceforge.net/mailarchive/message.php?msg_id=31338136
+    - cx_oracle developer commentary
+
+.. _cx_oracle_lob:
+
+LOB Objects
+-----------
+
+cx_oracle returns oracle LOBs using the cx_oracle.LOB object.  SQLAlchemy
+converts these to strings so that the interface of the Binary type is
+consistent with that of other backends, and so that the linkage to a live
+cursor is not needed in scenarios like result.fetchmany() and
+result.fetchall().   This means that by default, LOB objects are fully fetched
+unconditionally by SQLAlchemy, and the linkage to a live cursor is broken.
+
+To disable this processing, pass ``auto_convert_lobs=False`` to
+:func:`.create_engine()`.
+
+Two Phase Transaction Support
+-----------------------------
+
+Two Phase transactions are implemented using XA transactions, and are known
+to work in a rudimental fashion with recent versions of cx_Oracle
+as of SQLAlchemy 0.8.0b2, 0.7.10.   However, the mechanism is not yet
+considered to be robust and should still be regarded as experimental.
+
+In particular, the cx_Oracle DBAPI as recently as 5.1.2 has a bug regarding
+two phase which prevents
+a particular DBAPI connection from being consistently usable in both
+prepared transactions as well as traditional DBAPI usage patterns; therefore
+once a particular connection is used via :meth:`.Connection.begin_prepared`,
+all subsequent usages of the underlying DBAPI connection must be within
+the context of prepared transactions.
+
+The default behavior of :class:`.Engine` is to maintain a pool of DBAPI
+connections.  Therefore, due to the above glitch, a DBAPI connection that has
+been used in a two-phase operation, and is then returned to the pool, will
+not be usable in a non-two-phase context.   To avoid this situation,
+the application can make one of several choices:
+
+* Disable connection pooling using :class:`.NullPool`
+
+* Ensure that the particular :class:`.Engine` in use is only used
+  for two-phase operations.   A :class:`.Engine` bound to an ORM
+  :class:`.Session` which includes ``twophase=True`` will consistently
+  use the two-phase transaction style.
+
+* For ad-hoc two-phase operations without disabling pooling, the DBAPI
+  connection in use can be evicted from the connection pool using the
+  :meth:`.Connection.detach` method.
+
+.. versionchanged:: 0.8.0b2,0.7.10
+    Support for cx_oracle prepared transactions has been implemented
+    and tested.
+
+.. _cx_oracle_numeric:
+
+Precision Numerics
+------------------
+
+The SQLAlchemy dialect goes through a lot of steps to ensure
+that decimal numbers are sent and received with full accuracy.
+An "outputtypehandler" callable is associated with each
+cx_oracle connection object which detects numeric types and
+receives them as string values, instead of receiving a Python
+``float`` directly, which is then passed to the Python
+``Decimal`` constructor.  The :class:`.Numeric` and
+:class:`.Float` types under the cx_oracle dialect are aware of
+this behavior, and will coerce the ``Decimal`` to ``float`` if
+the ``asdecimal`` flag is ``False`` (default on :class:`.Float`,
+optional on :class:`.Numeric`).
+
+Because the handler coerces to ``Decimal`` in all cases first,
+the feature can detract significantly from performance.
+If precision numerics aren't required, the decimal handling
+can be disabled by passing the flag ``coerce_to_decimal=False``
+to :func:`.create_engine`::
+
+    engine = create_engine("oracle+cx_oracle://dsn", coerce_to_decimal=False)
+
+.. versionadded:: 0.7.6
+    Add the ``coerce_to_decimal`` flag.
+
+Another alternative to performance is to use the
+`cdecimal <http://pypi.python.org/pypi/cdecimal/>`_ library;
+see :class:`.Numeric` for additional notes.
+
+The handler attempts to use the "precision" and "scale"
+attributes of the result set column to best determine if
+subsequent incoming values should be received as ``Decimal`` as
+opposed to int (in which case no processing is added). There are
+several scenarios where OCI_ does not provide unambiguous data
+as to the numeric type, including some situations where
+individual rows may return a combination of floating point and
+integer values. Certain values for "precision" and "scale" have
+been observed to determine this scenario.  When it occurs, the
+outputtypehandler receives as string and then passes off to a
+processing function which detects, for each returned value, if a
+decimal point is present, and if so converts to ``Decimal``,
+otherwise to int.  The intention is that simple int-based
+statements like "SELECT my_seq.nextval() FROM DUAL" continue to
+return ints and not ``Decimal`` objects, and that any kind of
+floating point value is received as a string so that there is no
+floating point loss of precision.
+
+The "decimal point is present" logic itself is also sensitive to
+locale.  Under OCI_, this is controlled by the NLS_LANG
+environment variable. Upon first connection, the dialect runs a
+test to determine the current "decimal" character, which can be
+a comma "," for European locales. From that point forward the
+outputtypehandler uses that character to represent a decimal
+point. Note that cx_oracle 5.0.3 or greater is required
+when dealing with numerics with locale settings that don't use
+a period "." as the decimal character.
+
+.. versionchanged:: 0.6.6
+    The outputtypehandler supports the case where the locale uses a
+    comma "," character to represent a decimal point.

+.. dialect:: postgresql
+    :name: PostgreSQL
+
+
+Sequences/SERIAL
+----------------
+
+PostgreSQL supports sequences, and SQLAlchemy uses these as the default means
+of creating new primary key values for integer-based primary key columns. When
+creating tables, SQLAlchemy will issue the ``SERIAL`` datatype for
+integer-based primary key columns, which generates a sequence and server side
+default corresponding to the column.
+
+To specify a specific named sequence to be used for primary key generation,
+use the :func:`~sqlalchemy.schema.Sequence` construct::
+
+    Table('sometable', metadata,
+            Column('id', Integer, Sequence('some_id_seq'), primary_key=True)
+        )
+
+When SQLAlchemy issues a single INSERT statement, to fulfill the contract of
+having the "last insert identifier" available, a RETURNING clause is added to
+the INSERT statement which specifies the primary key columns should be
+returned after the statement completes. The RETURNING functionality only takes
+place if Postgresql 8.2 or later is in use. As a fallback approach, the
+sequence, whether specified explicitly or implicitly via ``SERIAL``, is
+executed independently beforehand, the returned value to be used in the
+subsequent insert. Note that when an
+:func:`~sqlalchemy.sql.expression.insert()` construct is executed using
+"executemany" semantics, the "last inserted identifier" functionality does not
+apply; no RETURNING clause is emitted nor is the sequence pre-executed in this
+case.
+
+To force the usage of RETURNING by default off, specify the flag
+``implicit_returning=False`` to :func:`.create_engine`.
+
+.. _postgresql_isolation_level:
+
+Transaction Isolation Level
+---------------------------
+
+All Postgresql dialects support setting of transaction isolation level
+both via a dialect-specific parameter ``isolation_level``
+accepted by :func:`.create_engine`,
+as well as the ``isolation_level`` argument as passed to
+:meth:`.Connection.execution_options`.  When using a non-psycopg2 dialect,
+this feature works by issuing the command
+``SET SESSION CHARACTERISTICS AS TRANSACTION ISOLATION LEVEL <level>`` for
+each new connection.
+
+To set isolation level using :func:`.create_engine`::
+
+    engine = create_engine(
+        "postgresql+pg8000://scott:tiger@localhost/test",
+        isolation_level="READ UNCOMMITTED"
+    )
+
+To set using per-connection execution options::
+
+    connection = engine.connect()
+    connection = connection.execution_options(
+        isolation_level="READ COMMITTED"
+    )
+
+Valid values for ``isolation_level`` include:
+
+* ``READ COMMITTED``
+* ``READ UNCOMMITTED``
+* ``REPEATABLE READ``
+* ``SERIALIZABLE``
+
+The :mod:`~sqlalchemy.dialects.postgresql.psycopg2` and
+:mod:`~sqlalchemy.dialects.postgresql.pg8000` dialects also offer the
+special level ``AUTOCOMMIT``.
+
+.. seealso::
+
+    :ref:`psycopg2_isolation_level`
+
+    :ref:`pg8000_isolation_level`
+
+.. _postgresql_schema_reflection:
+
+Remote-Schema Table Introspection and Postgresql search_path
+------------------------------------------------------------
+
+The Postgresql dialect can reflect tables from any schema.  The
+:paramref:`.Table.schema` argument, or alternatively the
+:paramref:`.MetaData.reflect.schema` argument determines which schema will
+be searched for the table or tables.   The reflected :class:`.Table` objects
+will in all cases retain this ``.schema`` attribute as was specified.
+However, with regards to tables which these :class:`.Table` objects refer to
+via foreign key constraint, a decision must be made as to how the ``.schema``
+is represented in those remote tables, in the case where that remote
+schema name is also a member of the current
+`Postgresql search path
+<http://www.postgresql.org/docs/9.0/static/ddl-schemas.html#DDL-SCHEMAS-PATH>`_.
+
+By default, the Postgresql dialect mimics the behavior encouraged by
+Postgresql's own ``pg_get_constraintdef()`` builtin procedure.  This function
+returns a sample definition for a particular foreign key constraint,
+omitting the referenced schema name from that definition when the name is
+also in the Postgresql schema search path.  The interaction below
+illustrates this behavior::
+
+    test=> CREATE TABLE test_schema.referred(id INTEGER PRIMARY KEY);
+    CREATE TABLE
+    test=> CREATE TABLE referring(
+    test(>         id INTEGER PRIMARY KEY,
+    test(>         referred_id INTEGER REFERENCES test_schema.referred(id));
+    CREATE TABLE
+    test=> SET search_path TO public, test_schema;
+    test=> SELECT pg_catalog.pg_get_constraintdef(r.oid, true) FROM
+    test-> pg_catalog.pg_class c JOIN pg_catalog.pg_namespace n
+    test-> ON n.oid = c.relnamespace

+     FOREIGN KEY (referred_id) REFERENCES referred(id)
+    (1 row)
+
+Above, we created a table ``referred`` as a member of the remote schema
+``test_schema``, however when we added ``test_schema`` to the
+PG ``search_path`` and then asked ``pg_get_constraintdef()`` for the
+``FOREIGN KEY`` syntax, ``test_schema`` was not included in the output of
+the function.
+
+On the other hand, if we set the search path back to the typical default
+of ``public``::
+
+    test=> SET search_path TO public;
+    SET
+
+The same query against ``pg_get_constraintdef()`` now returns the fully
+schema-qualified name for us::
+
+    test=> SELECT pg_catalog.pg_get_constraintdef(r.oid, true) FROM
+    test-> pg_catalog.pg_class c JOIN pg_catalog.pg_namespace n
+    test-> ON n.oid = c.relnamespace
+    test-> JOIN pg_catalog.pg_constraint r  ON c.oid = r.conrelid
+    test-> WHERE c.relname='referring' AND r.contype = 'f';
+                         pg_get_constraintdef
+    ---------------------------------------------------------------
+     FOREIGN KEY (referred_id) REFERENCES test_schema.referred(id)
+    (1 row)
+
+SQLAlchemy will by default use the return value of ``pg_get_constraintdef()``
+in order to determine the remote schema name.  That is, if our ``search_path``
+were set to include ``test_schema``, and we invoked a table
+reflection process as follows::
+
+    >>> from sqlalchemy import Table, MetaData, create_engine
+    >>> engine = create_engine("postgresql://scott:tiger@localhost/test")
+    >>> with engine.connect() as conn:
+    ...     conn.execute("SET search_path TO test_schema, public")
+    ...     meta = MetaData()
+    ...     referring = Table('referring', meta,
+    ...                       autoload=True, autoload_with=conn)
+    ...
+    <sqlalchemy.engine.result.ResultProxy object at 0x101612ed0>
+
+The above process would deliver to the :attr:`.MetaData.tables` collection
+``referred`` table named **without** the schema::
+
+    >>> meta.tables['referred'].schema is None
+    True
+
+To alter the behavior of reflection such that the referred schema is
+maintained regardless of the ``search_path`` setting, use the
+``postgresql_ignore_search_path`` option, which can be specified as a
+dialect-specific argument to both :class:`.Table` as well as
+:meth:`.MetaData.reflect`::
+
+    >>> with engine.connect() as conn:
+    ...     conn.execute("SET search_path TO test_schema, public")
+    ...     meta = MetaData()
+    ...     referring = Table('referring', meta, autoload=True,
+    ...                       autoload_with=conn,
+    ...                       postgresql_ignore_search_path=True)
+    ...
+    <sqlalchemy.engine.result.ResultProxy object at 0x1016126d0>
+
+We will now have ``test_schema.referred`` stored as schema-qualified::
+
+    >>> meta.tables['test_schema.referred'].schema
+    'test_schema'
+
+.. sidebar:: Best Practices for Postgresql Schema reflection
+
+    The description of Postgresql schema reflection behavior is complex, and
+    is the product of many years of dealing with widely varied use cases and
+    user preferences. But in fact, there's no need to understand any of it if
+    you just stick to the simplest use pattern: leave the ``search_path`` set
+    to its default of ``public`` only, never refer to the name ``public`` as
+    an explicit schema name otherwise, and refer to all other schema names
+    explicitly when building up a :class:`.Table` object.  The options
+    described here are only for those users who can't, or prefer not to, stay
+    within these guidelines.
+
+Note that **in all cases**, the "default" schema is always reflected as
+``None``. The "default" schema on Postgresql is that which is returned by the
+Postgresql ``current_schema()`` function.  On a typical Postgresql
+installation, this is the name ``public``.  So a table that refers to another
+which is in the ``public`` (i.e. default) schema will always have the
+``.schema`` attribute set to ``None``.
+
+.. versionadded:: 0.9.2 Added the ``postgresql_ignore_search_path``
+   dialect-level option accepted by :class:`.Table` and
+   :meth:`.MetaData.reflect`.
+
+
+.. seealso::
+
+        `The Schema Search Path
+        <http://www.postgresql.org/docs/9.0/static/ddl-schemas.html#DDL-SCHEMAS-PATH>`_
+        - on the Postgresql website.
+
+INSERT/UPDATE...RETURNING
+-------------------------
+
+The dialect supports PG 8.2's ``INSERT..RETURNING``, ``UPDATE..RETURNING`` and
+``DELETE..RETURNING`` syntaxes.   ``INSERT..RETURNING`` is used by default
+for single-row INSERT statements in order to fetch newly generated
+primary key identifiers.   To specify an explicit ``RETURNING`` clause,
+use the :meth:`._UpdateBase.returning` method on a per-statement basis::
+
+    # INSERT..RETURNING
+    result = table.insert().returning(table.c.col1, table.c.col2).\\
+        values(name='foo')
+    print result.fetchall()
+
+    # UPDATE..RETURNING
+    result = table.update().returning(table.c.col1, table.c.col2).\\
+        where(table.c.name=='foo').values(name='bar')
+    print result.fetchall()
+
+    # DELETE..RETURNING
+    result = table.delete().returning(table.c.col1, table.c.col2).\\
+        where(table.c.name=='foo')
+    print result.fetchall()
+
+.. _postgresql_match:
+
+Full Text Search
+----------------
+
+SQLAlchemy makes available the Postgresql ``@@`` operator via the
+:meth:`.ColumnElement.match` method on any textual column expression.
+On a Postgresql dialect, an expression like the following::
+
+    select([sometable.c.text.match("search string")])
+
+will emit to the database::
+
+    SELECT text @@ to_tsquery('search string') FROM table
+
+The Postgresql text search functions such as ``to_tsquery()``
+and ``to_tsvector()`` are available
+explicitly using the standard :attr:`.func` construct.  For example::
+
+    select([
+        func.to_tsvector('fat cats ate rats').match('cat & rat')
+    ])
+
+Emits the equivalent of::
+
+    SELECT to_tsvector('fat cats ate rats') @@ to_tsquery('cat & rat')
+
+The :class:`.postgresql.TSVECTOR` type can provide for explicit CAST::
+
+    from sqlalchemy.dialects.postgresql import TSVECTOR
+    from sqlalchemy import select, cast
+    select([cast("some text", TSVECTOR)])
+
+produces a statement equivalent to::
+
+    SELECT CAST('some text' AS TSVECTOR) AS anon_1
+
+Full Text Searches in Postgresql are influenced by a combination of: the
+PostgresSQL setting of ``default_text_search_config``, the ``regconfig`` used
+to build the GIN/GiST indexes, and the ``regconfig`` optionally passed in
+during a query.
+
+When performing a Full Text Search against a column that has a GIN or
+GiST index that is already pre-computed (which is common on full text
+searches) one may need to explicitly pass in a particular PostgresSQL
+``regconfig`` value to ensure the query-planner utilizes the index and does
+not re-compute the column on demand.
+
+In order to provide for this explicit query planning, or to use different
+search strategies, the ``match`` method accepts a ``postgresql_regconfig``
+keyword argument.
+
+    select([mytable.c.id]).where(
+        mytable.c.title.match('somestring', postgresql_regconfig='english')
+    )
+
+Emits the equivalent of::
+
+    SELECT mytable.id FROM mytable
+    WHERE mytable.title @@ to_tsquery('english', 'somestring')
+
+One can also specifically pass in a `'regconfig'` value to the
+``to_tsvector()`` command as the initial argument.
+
+    select([mytable.c.id]).where(
+            func.to_tsvector('english', mytable.c.title )\
+            .match('somestring', postgresql_regconfig='english')
+        )
+
+produces a statement equivalent to::
+
+    SELECT mytable.id FROM mytable
+    WHERE to_tsvector('english', mytable.title) @@
+        to_tsquery('english', 'somestring')
+
+It is recommended that you use the ``EXPLAIN ANALYZE...`` tool from
+PostgresSQL to ensure that you are generating queries with SQLAlchemy that
+take full advantage of any indexes you may have created for full text search.
+
+FROM ONLY ...
+------------------------
+
+The dialect supports PostgreSQL's ONLY keyword for targeting only a particular
+table in an inheritance hierarchy. This can be used to produce the
+``SELECT ... FROM ONLY``, ``UPDATE ONLY ...``, and ``DELETE FROM ONLY ...``
+syntaxes. It uses SQLAlchemy's hints mechanism::
+
+    # SELECT ... FROM ONLY ...
+    result = table.select().with_hint(table, 'ONLY', 'postgresql')
+    print result.fetchall()
+
+    # UPDATE ONLY ...
+    table.update(values=dict(foo='bar')).with_hint('ONLY',
+                                                   dialect_name='postgresql')
+
+    # DELETE FROM ONLY ...
+    table.delete().with_hint('ONLY', dialect_name='postgresql')
+
+.. _postgresql_indexes:
+
+Postgresql-Specific Index Options
+---------------------------------
+
+Several extensions to the :class:`.Index` construct are available, specific
+to the PostgreSQL dialect.
+
+Partial Indexes
+^^^^^^^^^^^^^^^^
+
+Partial indexes add criterion to the index definition so that the index is
+applied to a subset of rows.   These can be specified on :class:`.Index`
+using the ``postgresql_where`` keyword argument::
+
+  Index('my_index', my_table.c.id, postgresql_where=tbl.c.value > 10)
+
+Operator Classes
+^^^^^^^^^^^^^^^^^
+
+PostgreSQL allows the specification of an *operator class* for each column of
+an index (see
+http://www.postgresql.org/docs/8.3/interactive/indexes-opclass.html).
+The :class:`.Index` construct allows these to be specified via the
+``postgresql_ops`` keyword argument::
+
+    Index('my_index', my_table.c.id, my_table.c.data,
+                            postgresql_ops={
+                                'data': 'text_pattern_ops',
+                                'id': 'int4_ops'
+                            })
+
+.. versionadded:: 0.7.2
+    ``postgresql_ops`` keyword argument to :class:`.Index` construct.
+
+Note that the keys in the ``postgresql_ops`` dictionary are the "key" name of
+the :class:`.Column`, i.e. the name used to access it from the ``.c``
+collection of :class:`.Table`, which can be configured to be different than
+the actual name of the column as expressed in the database.
+
+Index Types
+^^^^^^^^^^^^
+
+PostgreSQL provides several index types: B-Tree, Hash, GiST, and GIN, as well
+as the ability for users to create their own (see
+http://www.postgresql.org/docs/8.3/static/indexes-types.html). These can be
+specified on :class:`.Index` using the ``postgresql_using`` keyword argument::
+
+    Index('my_index', my_table.c.data, postgresql_using='gin')
+
+The value passed to the keyword argument will be simply passed through to the
+underlying CREATE INDEX command, so it *must* be a valid index type for your
+version of PostgreSQL.

+                data=[1,2,3]
+        )
+
+    The :class:`.ARRAY` type can be constructed given a fixed number
+    of dimensions::
+
+        mytable = Table("mytable", metadata,
+                Column("data", ARRAY(Integer, dimensions=2))
+            )
+
+    This has the effect of the :class:`.ARRAY` type
+    specifying that number of bracketed blocks when a :class:`.Table`
+    is used in a CREATE TABLE statement, or when the type is used
+    within a :func:`.expression.cast` construct; it also causes
+    the bind parameter and result set processing of the type
+    to optimize itself to expect exactly that number of dimensions.
+    Note that Postgresql itself still allows N dimensions with such a type.
+
+    SQL expressions of type :class:`.ARRAY` have support for "index" and
+    "slice" behavior.  The Python ``[]`` operator works normally here, given
+    integer indexes or slices.  Note that Postgresql arrays default
+    to 1-based indexing.  The operator produces binary expression
+    constructs which will produce the appropriate SQL, both for
+    SELECT statements::
+
+        select([mytable.c.data[5], mytable.c.data[2:7]])
+
+    as well as UPDATE statements when the :meth:`.Update.values` method
+    is used::
+
+        mytable.update().values({
+            mytable.c.data[5]: 7,
+            mytable.c.data[2:7]: [1, 2, 3]
+        })
+
+    :class:`.ARRAY` provides special methods for containment operations,
+    e.g.::
+
+        mytable.c.data.contains([1, 2])
+
+    For a full list of special methods see :class:`.ARRAY.Comparator`.
+
+    .. versionadded:: 0.8 Added support for index and slice operations
+       to the :class:`.ARRAY` type, including support for UPDATE
+       statements, and special array containment operations.
+
+    The :class:`.ARRAY` type may not be supported on all DBAPIs.
+    It is known to work on psycopg2 and not pg8000.
+
+    See also:
+
+    :class:`.postgresql.array` - produce a literal array value.

+Unicode
+-------
+
+When communicating with the server, pg8000 **always uses the server-side
+character set**.  SQLAlchemy has no ability to modify what character set
+pg8000 chooses to use, and additionally SQLAlchemy does no unicode conversion
+of any kind with the pg8000 backend. The origin of the client encoding setting
+is ultimately the CLIENT_ENCODING setting in postgresql.conf.
+
+It is not necessary, though is also harmless, to pass the "encoding" parameter
+to :func:`.create_engine` when using pg8000.

+
+psycopg2 Connect Arguments
+-----------------------------------
+
+psycopg2-specific keyword arguments which are accepted by
+:func:`.create_engine()` are:
+
+* ``server_side_cursors``: Enable the usage of "server side cursors" for SQL
+  statements which support this feature. What this essentially means from a
+  psycopg2 point of view is that the cursor is created using a name, e.g.
+  ``connection.cursor('some name')``, which has the effect that result rows
+  are not immediately pre-fetched and buffered after statement execution, but
+  are instead left on the server and only retrieved as needed. SQLAlchemy's
+  :class:`~sqlalchemy.engine.ResultProxy` uses special row-buffering
+  behavior when this feature is enabled, such that groups of 100 rows at a
+  time are fetched over the wire to reduce conversational overhead.
+  Note that the ``stream_results=True`` execution option is a more targeted
+  way of enabling this mode on a per-execution basis.
+* ``use_native_unicode``: Enable the usage of Psycopg2 "native unicode" mode
+  per connection.  True by default.
+* ``isolation_level``: This option, available for all PostgreSQL dialects,
+  includes the ``AUTOCOMMIT`` isolation level when using the psycopg2
+  dialect.  See :ref:`psycopg2_isolation_level`.
+
+
+Unix Domain Connections
+------------------------
+
+psycopg2 supports connecting via Unix domain connections.   When the ``host``
+portion of the URL is omitted, SQLAlchemy passes ``None`` to psycopg2,
+which specifies Unix-domain communication rather than TCP/IP communication::
+
+    create_engine("postgresql+psycopg2://user:password@/dbname")
+
+By default, the socket file used is to connect to a Unix-domain socket
+in ``/tmp``, or whatever socket directory was specified when PostgreSQL
+was built.  This value can be overridden by passing a pathname to psycopg2,
+using ``host`` as an additional keyword argument::
+
+    create_engine("postgresql+psycopg2://user:password@/dbname?host=/var/lib/postgresql")
+
+See also:
+
+`PQconnectdbParams <http://www.postgresql.org/docs/9.1/static\
+/libpq-connect.html#LIBPQ-PQCONNECTDBPARAMS>`_
+
+Per-Statement/Connection Execution Options
+-------------------------------------------
+
+The following DBAPI-specific options are respected when used with
+:meth:`.Connection.execution_options`, :meth:`.Executable.execution_options`,
+:meth:`.Query.execution_options`, in addition to those not specific to DBAPIs:
+
+* isolation_level - Set the transaction isolation level for the lifespan of a
+  :class:`.Connection` (can only be set on a connection, not a statement
+  or query).   See :ref:`psycopg2_isolation_level`.
+
+* stream_results - Enable or disable usage of psycopg2 server side cursors -
+  this feature makes use of "named" cursors in combination with special
+  result handling methods so that result rows are not fully buffered.
+  If ``None`` or not set, the ``server_side_cursors`` option of the
+  :class:`.Engine` is used.
+
+Unicode
+-------
+
+By default, the psycopg2 driver uses the ``psycopg2.extensions.UNICODE``
+extension, such that the DBAPI receives and returns all strings as Python
+Unicode objects directly - SQLAlchemy passes these values through without
+change.   Psycopg2 here will encode/decode string values based on the
+current "client encoding" setting; by default this is the value in
+the ``postgresql.conf`` file, which often defaults to ``SQL_ASCII``.
+Typically, this can be changed to ``utf-8``, as a more useful default::
+
+    #client_encoding = sql_ascii # actually, defaults to database
+                                 # encoding
+    client_encoding = utf8
+
+A second way to affect the client encoding is to set it within Psycopg2
+locally.   SQLAlchemy will call psycopg2's ``set_client_encoding()``
+method (see:
+http://initd.org/psycopg/docs/connection.html#connection.set_client_encoding)
+on all new connections based on the value passed to
+:func:`.create_engine` using the ``client_encoding`` parameter::
+
+    engine = create_engine("postgresql://user:pass@host/dbname",
+                           client_encoding='utf8')
+
+This overrides the encoding specified in the Postgresql client configuration.
+
+.. versionadded:: 0.7.3
+    The psycopg2-specific ``client_encoding`` parameter to
+    :func:`.create_engine`.
+
+SQLAlchemy can also be instructed to skip the usage of the psycopg2
+``UNICODE`` extension and to instead utilize its own unicode encode/decode
+services, which are normally reserved only for those DBAPIs that don't
+fully support unicode directly.  Passing ``use_native_unicode=False`` to
+:func:`.create_engine` will disable usage of ``psycopg2.extensions.UNICODE``.
+SQLAlchemy will instead encode data itself into Python bytestrings on the way
+in and coerce from bytes on the way back,
+using the value of the :func:`.create_engine` ``encoding`` parameter, which
+defaults to ``utf-8``.
+SQLAlchemy's own unicode encode/decode functionality is steadily becoming
+obsolete as more DBAPIs support unicode fully along with the approach of
+Python 3; in modern usage psycopg2 should be relied upon to handle unicode.
+
+Transactions
+------------
+
+The psycopg2 dialect fully supports SAVEPOINT and two-phase commit operations.
+
+.. _psycopg2_isolation_level:
+
+Psycopg2 Transaction Isolation Level
+-------------------------------------
+
+As discussed in :ref:`postgresql_isolation_level`,
+all Postgresql dialects support setting of transaction isolation level
+both via the ``isolation_level`` parameter passed to :func:`.create_engine`,
+as well as the ``isolation_level`` argument used by
+:meth:`.Connection.execution_options`.  When using the psycopg2 dialect, these
+options make use of psycopg2's ``set_isolation_level()`` connection method,
+rather than emitting a Postgresql directive; this is because psycopg2's
+API-level setting is always emitted at the start of each transaction in any
+case.
+
+The psycopg2 dialect supports these constants for isolation level:
+
+* ``READ COMMITTED``
+* ``READ UNCOMMITTED``
+* ``REPEATABLE READ``
+* ``SERIALIZABLE``
+* ``AUTOCOMMIT``
+
+.. versionadded:: 0.8.2 support for AUTOCOMMIT isolation level when using
+   psycopg2.
+
+.. seealso::
+
+    :ref:`postgresql_isolation_level`
+
+    :ref:`pg8000_isolation_level`
+
+
+NOTICE logging
+---------------
+
+The psycopg2 dialect will log Postgresql NOTICE messages via the
+``sqlalchemy.dialects.postgresql`` logger::
+
+    import logging
+    logging.getLogger('sqlalchemy.dialects.postgresql').setLevel(logging.INFO)
+
+.. _psycopg2_hstore::
+
+HSTORE type
+------------
+
+The ``psycopg2`` DBAPI includes an extension to natively handle marshalling of
+the HSTORE type.   The SQLAlchemy psycopg2 dialect will enable this extension
+by default when it is detected that the target database has the HSTORE
+type set up for use.   In other words, when the dialect makes the first
+connection, a sequence like the following is performed:
+
+1. Request the available HSTORE oids using
+   ``psycopg2.extras.HstoreAdapter.get_oids()``.
+   If this function returns a list of HSTORE identifiers, we then determine
+   that the ``HSTORE`` extension is present.
+
+2. If the ``use_native_hstore`` flag is at its default of ``True``, and
+   we've detected that ``HSTORE`` oids are available, the
+   ``psycopg2.extensions.register_hstore()`` extension is invoked for all
+   connections.
+
+The ``register_hstore()`` extension has the effect of **all Python
+dictionaries being accepted as parameters regardless of the type of target
+column in SQL**. The dictionaries are converted by this extension into a
+textual HSTORE expression.  If this behavior is not desired, disable the
+use of the hstore extension by setting ``use_native_hstore`` to ``False`` as
+follows::
+
+    engine = create_engine("postgresql+psycopg2://scott:tiger@localhost/test",
+                use_native_hstore=False)
+
+The ``HSTORE`` type is **still supported** when the
+``psycopg2.extensions.register_hstore()`` extension is not used.  It merely
+means that the coercion between Python dictionaries and the HSTORE
+string format, on both the parameter side and the result side, will take
+place within SQLAlchemy's own marshalling logic, and not that of ``psycopg2``
+which may be more performant.

+.. dialect:: sqlite
+    :name: SQLite
+
+
+Date and Time Types
+-------------------
+
+SQLite does not have built-in DATE, TIME, or DATETIME types, and pysqlite does
+not provide out of the box functionality for translating values between Python
+`datetime` objects and a SQLite-supported format. SQLAlchemy's own
+:class:`~sqlalchemy.types.DateTime` and related types provide date formatting
+and parsing functionality when SQlite is used. The implementation classes are
+:class:`~.sqlite.DATETIME`, :class:`~.sqlite.DATE` and :class:`~.sqlite.TIME`.
+These types represent dates and times as ISO formatted strings, which also
+nicely support ordering. There's no reliance on typical "libc" internals for
+these functions so historical dates are fully supported.
+
+.. _sqlite_autoincrement:
+
+SQLite Auto Incrementing Behavior
+----------------------------------
+
+Background on SQLite's autoincrement is at: http://sqlite.org/autoinc.html
+
+Two things to note:
+
+* The AUTOINCREMENT keyword is **not** required for SQLite tables to
+  generate primary key values automatically. AUTOINCREMENT only means that the
+  algorithm used to generate ROWID values should be slightly different.
+* SQLite does **not** generate primary key (i.e. ROWID) values, even for
+  one column, if the table has a composite (i.e. multi-column) primary key.
+  This is regardless of the AUTOINCREMENT keyword being present or not.
+
+To specifically render the AUTOINCREMENT keyword on the primary key column
+when rendering DDL, add the flag ``sqlite_autoincrement=True`` to the Table
+construct::
+
+    Table('sometable', metadata,
+            Column('id', Integer, primary_key=True),
+            sqlite_autoincrement=True)
+
+Transaction Isolation Level
+---------------------------
+
+:func:`.create_engine` accepts an ``isolation_level`` parameter which results
+in the command ``PRAGMA read_uncommitted <level>`` being invoked for every new
+connection. Valid values for this parameter are ``SERIALIZABLE`` and ``READ
+UNCOMMITTED`` corresponding to a value of 0 and 1, respectively. See the
+section :ref:`pysqlite_serializable` for an important workaround when using
+serializable isolation with Pysqlite.
+
+Database Locking Behavior / Concurrency
+---------------------------------------
+
+Note that SQLite is not designed for a high level of concurrency. The database
+itself, being a file, is locked completely during write operations and within
+transactions, meaning exactly one connection has exclusive access to the
+database during this period - all other connections will be blocked during
+this time.
+
+The Python DBAPI specification also calls for a connection model that is
+always in a transaction; there is no BEGIN method, only commit and rollback.
+This implies that a SQLite DBAPI driver would technically allow only
+serialized access to a particular database file at all times. The pysqlite
+driver attempts to ameliorate this by deferring the actual BEGIN statement
+until the first DML (INSERT, UPDATE, or DELETE) is received within a
+transaction. While this breaks serializable isolation, it at least delays the
+exclusive locking inherent in SQLite's design.
+
+SQLAlchemy's default mode of usage with the ORM is known as
+"autocommit=False", which means the moment the :class:`.Session` begins to be
+used, a transaction is begun. As the :class:`.Session` is used, the autoflush
+feature, also on by default, will flush out pending changes to the database
+before each query. The effect of this is that a :class:`.Session` used in its
+default mode will often emit DML early on, long before the transaction is
+actually committed. This again will have the effect of serializing access to
+the SQLite database. If highly concurrent reads are desired against the SQLite
+database, it is advised that the autoflush feature be disabled, and
+potentially even that autocommit be re-enabled, which has the effect of each
+SQL statement and flush committing changes immediately.
+
+For more information on SQLite's lack of concurrency by design, please see
+`Situations Where Another RDBMS May Work Better - High Concurrency
+<http://www.sqlite.org/whentouse.html>`_ near the bottom of the page.
+
+.. _sqlite_foreign_keys:
+
+Foreign Key Support
+-------------------
+
+SQLite supports FOREIGN KEY syntax when emitting CREATE statements for tables,
+however by default these constraints have no effect on the operation of the
+table.
+
+Constraint checking on SQLite has three prerequisites:
+
+* At least version 3.6.19 of SQLite must be in use
+* The SQLite library must be compiled *without* the SQLITE_OMIT_FOREIGN_KEY
+  or SQLITE_OMIT_TRIGGER symbols enabled.
+* The ``PRAGMA foreign_keys = ON`` statement must be emitted on all
+  connections before use.
+
+SQLAlchemy allows for the ``PRAGMA`` statement to be emitted automatically for
+new connections through the usage of events::
+
+    from sqlalchemy.engine import Engine
+    from sqlalchemy import event
+
+    @event.listens_for(Engine, "connect")
+    def set_sqlite_pragma(dbapi_connection, connection_record):
+        cursor = dbapi_connection.cursor()
+        cursor.execute("PRAGMA foreign_keys=ON")
+        cursor.close()
+
+.. seealso::
+
+    `SQLite Foreign Key Support <http://www.sqlite.org/foreignkeys.html>`_
+    - on the SQLite web site.
+
+    :ref:`event_toplevel` - SQLAlchemy event API.
+
+.. _sqlite_type_reflection:
+
+Type Reflection
+---------------
+
+SQLite types are unlike those of most other database backends, in that
+the string name of the type usually does not correspond to a "type" in a
+one-to-one fashion.  Instead, SQLite links per-column typing behavior
+to one of five so-called "type affinities" based on a string matching
+pattern for the type.
+
+SQLAlchemy's reflection process, when inspecting types, uses a simple
+lookup table to link the keywords returned to provided SQLAlchemy types.
+This lookup table is present within the SQLite dialect as it is for all
+other dialects.  However, the SQLite dialect has a different "fallback"
+routine for when a particular type name is not located in the lookup map;
+it instead implements the SQLite "type affinity" scheme located at
+http://www.sqlite.org/datatype3.html section 2.1.
+
+The provided typemap will make direct associations from an exact string
+name match for the following types:
+
+:class:`~.types.BIGINT`, :class:`~.types.BLOB`,
+:class:`~.types.BOOLEAN`, :class:`~.types.BOOLEAN`,
+:class:`~.types.CHAR`, :class:`~.types.DATE`,
+:class:`~.types.DATETIME`, :class:`~.types.FLOAT`,
+:class:`~.types.DECIMAL`, :class:`~.types.FLOAT`,
+:class:`~.types.INTEGER`, :class:`~.types.INTEGER`,
+:class:`~.types.NUMERIC`, :class:`~.types.REAL`,
+:class:`~.types.SMALLINT`, :class:`~.types.TEXT`,
+:class:`~.types.TIME`, :class:`~.types.TIMESTAMP`,
+:class:`~.types.VARCHAR`, :class:`~.types.NVARCHAR`,
+:class:`~.types.NCHAR`
+
+When a type name does not match one of the above types, the "type affinity"
+lookup is used instead:
+
+* :class:`~.types.INTEGER` is returned if the type name includes the
+  string ``INT``
+* :class:`~.types.TEXT` is returned if the type name includes the
+  string ``CHAR``, ``CLOB`` or ``TEXT``
+* :class:`~.types.NullType` is returned if the type name includes the
+  string ``BLOB``
+* :class:`~.types.REAL` is returned if the type name includes the string
+  ``REAL``, ``FLOA`` or ``DOUB``.
+* Otherwise, the :class:`~.types.NUMERIC` type is used.
+
+.. versionadded:: 0.9.3 Support for SQLite type affinity rules when reflecting
+   columns.

+.. dialect:: sqlite+pysqlite
+    :name: pysqlite
+    :dbapi: sqlite3
+    :connectstring: sqlite+pysqlite:///file_path
+    :url: http://docs.python.org/library/sqlite3.html
+
+    Note that ``pysqlite`` is the same driver as the ``sqlite3``
+    module included with the Python distribution.
+
+Driver
+------
+
+When using Python 2.5 and above, the built in ``sqlite3`` driver is
+already installed and no additional installation is needed.  Otherwise,
+the ``pysqlite2`` driver needs to be present.  This is the same driver as
+``sqlite3``, just with a different name.
+
+The ``pysqlite2`` driver will be loaded first, and if not found, ``sqlite3``
+is loaded.  This allows an explicitly installed pysqlite driver to take
+precedence over the built in one.   As with all dialects, a specific
+DBAPI module may be provided to :func:`~sqlalchemy.create_engine()` to control
+this explicitly::
+
+    from sqlite3 import dbapi2 as sqlite
+    e = create_engine('sqlite+pysqlite:///file.db', module=sqlite)
+
+
+Connect Strings
+---------------
+
+The file specification for the SQLite database is taken as the "database"
+portion of the URL.  Note that the format of a SQLAlchemy url is::
+
+    driver://user:pass@host/database
+
+This means that the actual filename to be used starts with the characters to
+the **right** of the third slash.   So connecting to a relative filepath
+looks like::
+
+    # relative path
+    e = create_engine('sqlite:///path/to/database.db')
+
+An absolute path, which is denoted by starting with a slash, means you
+need **four** slashes::
+
+    # absolute path
+    e = create_engine('sqlite:////path/to/database.db')
+
+To use a Windows path, regular drive specifications and backslashes can be
+used. Double backslashes are probably needed::
+
+    # absolute path on Windows
+    e = create_engine('sqlite:///C:\\\\path\\\\to\\\\database.db')
+
+The sqlite ``:memory:`` identifier is the default if no filepath is
+present.  Specify ``sqlite://`` and nothing else::
+
+    # in-memory database
+    e = create_engine('sqlite://')
+
+Compatibility with sqlite3 "native" date and datetime types
+-----------------------------------------------------------
+
+The pysqlite driver includes the sqlite3.PARSE_DECLTYPES and
+sqlite3.PARSE_COLNAMES options, which have the effect of any column
+or expression explicitly cast as "date" or "timestamp" will be converted
+to a Python date or datetime object.  The date and datetime types provided
+with the pysqlite dialect are not currently compatible with these options,
+since they render the ISO date/datetime including microseconds, which
+pysqlite's driver does not.   Additionally, SQLAlchemy does not at
+this time automatically render the "cast" syntax required for the
+freestanding functions "current_timestamp" and "current_date" to return
+datetime/date types natively.   Unfortunately, pysqlite
+does not provide the standard DBAPI types in ``cursor.description``,
+leaving SQLAlchemy with no way to detect these types on the fly
+without expensive per-row type checks.
+
+Keeping in mind that pysqlite's parsing option is not recommended,
+nor should be necessary, for use with SQLAlchemy, usage of PARSE_DECLTYPES
+can be forced if one configures "native_datetime=True" on create_engine()::
+
+    engine = create_engine('sqlite://',
+        connect_args={'detect_types':
+            sqlite3.PARSE_DECLTYPES|sqlite3.PARSE_COLNAMES},
+        native_datetime=True
+    )
+
+With this flag enabled, the DATE and TIMESTAMP types (but note - not the
+DATETIME or TIME types...confused yet ?) will not perform any bind parameter
+or result processing. Execution of "func.current_date()" will return a string.
+"func.current_timestamp()" is registered as returning a DATETIME type in
+SQLAlchemy, so this function still receives SQLAlchemy-level result
+processing.
+
+.. _pysqlite_threading_pooling:
+
+Threading/Pooling Behavior
+---------------------------
+
+Pysqlite's default behavior is to prohibit the usage of a single connection
+in more than one thread.   This is originally intended to work with older
+versions of SQLite that did not support multithreaded operation under
+various circumstances.  In particular, older SQLite versions
+did not allow a ``:memory:`` database to be used in multiple threads
+under any circumstances.
+
+Pysqlite does include a now-undocumented flag known as
+``check_same_thread`` which will disable this check, however note that
+pysqlite connections are still not safe to use in concurrently in multiple
+threads.  In particular, any statement execution calls would need to be
+externally mutexed, as Pysqlite does not provide for thread-safe propagation
+of error messages among other things.   So while even ``:memory:`` databases
+can be shared among threads in modern SQLite, Pysqlite doesn't provide enough
+thread-safety to make this usage worth it.
+
+SQLAlchemy sets up pooling to work with Pysqlite's default behavior:
+
+* When a ``:memory:`` SQLite database is specified, the dialect by default
+  will use :class:`.SingletonThreadPool`. This pool maintains a single
+  connection per thread, so that all access to the engine within the current
+  thread use the same ``:memory:`` database - other threads would access a
+  different ``:memory:`` database.
+* When a file-based database is specified, the dialect will use
+  :class:`.NullPool` as the source of connections. This pool closes and
+  discards connections which are returned to the pool immediately. SQLite
+  file-based connections have extremely low overhead, so pooling is not
+  necessary. The scheme also prevents a connection from being used again in
+  a different thread and works best with SQLite's coarse-grained file locking.
+
+  .. versionchanged:: 0.7
+      Default selection of :class:`.NullPool` for SQLite file-based databases.
+      Previous versions select :class:`.SingletonThreadPool` by
+      default for all SQLite databases.
+
+
+Using a Memory Database in Multiple Threads
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To use a ``:memory:`` database in a multithreaded scenario, the same
+connection object must be shared among threads, since the database exists
+only within the scope of that connection.   The
+:class:`.StaticPool` implementation will maintain a single connection
+globally, and the ``check_same_thread`` flag can be passed to Pysqlite
+as ``False``::
+
+    from sqlalchemy.pool import StaticPool
+    engine = create_engine('sqlite://',
+                        connect_args={'check_same_thread':False},
+                        poolclass=StaticPool)
+
+Note that using a ``:memory:`` database in multiple threads requires a recent
+version of SQLite.
+
+Using Temporary Tables with SQLite
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Due to the way SQLite deals with temporary tables, if you wish to use a
+temporary table in a file-based SQLite database across multiple checkouts
+from the connection pool, such as when using an ORM :class:`.Session` where
+the temporary table should continue to remain after :meth:`.Session.commit` or
+:meth:`.Session.rollback` is called, a pool which maintains a single
+connection must be used.   Use :class:`.SingletonThreadPool` if the scope is
+only needed within the current thread, or :class:`.StaticPool` is scope is
+needed within multiple threads for this case::
+
+    # maintain the same connection per thread
+    from sqlalchemy.pool import SingletonThreadPool
+    engine = create_engine('sqlite:///mydb.db',
+                        poolclass=SingletonThreadPool)
+
+
+    # maintain the same connection across all threads
+    from sqlalchemy.pool import StaticPool
+    engine = create_engine('sqlite:///mydb.db',
+                        poolclass=StaticPool)
+
+Note that :class:`.SingletonThreadPool` should be configured for the number
+of threads that are to be used; beyond that number, connections will be
+closed out in a non deterministic way.
+
+Unicode
+-------
+
+The pysqlite driver only returns Python ``unicode`` objects in result sets,
+never plain strings, and accommodates ``unicode`` objects within bound
+parameter values in all cases.   Regardless of the SQLAlchemy string type in
+use, string-based result values will by Python ``unicode`` in Python 2.
+The :class:`.Unicode` type should still be used to indicate those columns that
+require unicode, however, so that non-``unicode`` values passed inadvertently
+will emit a warning.  Pysqlite will emit an error if a non-``unicode`` string
+is passed containing non-ASCII characters.
+
+.. _pysqlite_serializable:
+
+Serializable Transaction Isolation
+----------------------------------
+
+The pysqlite DBAPI driver has a long-standing bug in which transactional
+state is not begun until the first DML statement, that is INSERT, UPDATE
+or DELETE, is emitted.  A SELECT statement will not cause transactional
+state to begin.   While this mode of usage is fine for typical situations
+and has the advantage that the SQLite database file is not prematurely
+locked, it breaks serializable transaction isolation, which requires
+that the database file be locked upon any SQL being emitted.
+
+To work around this issue, the ``BEGIN`` keyword can be emitted
+at the start of each transaction.   The following recipe establishes
+a :meth:`.ConnectionEvents.begin` handler to achieve this::
+
+    from sqlalchemy import create_engine, event
+
+    engine = create_engine("sqlite:///myfile.db",
+                           isolation_level='SERIALIZABLE')
+
+    @event.listens_for(engine, "begin")
+    def do_begin(conn):
+        conn.execute("BEGIN")

+"""SQL connections, SQL execution and high-level DB-API interface.
+
+The engine package defines the basic components used to interface
+DB-API modules with higher-level statement construction,
+connection-management, execution and result contexts.  The primary
+"entry point" class into this package is the Engine and its public
+constructor ``create_engine()``.
+
+This package includes:
+
+base.py
+    Defines interface classes and some implementation classes which
+    comprise the basic components used to interface between a DB-API,
+    constructed and plain-text statements, connections, transactions,
+    and results.
+
+default.py
+    Contains default implementations of some of the components defined
+    in base.py.  All current database dialects use the classes in
+    default.py as base classes for their own database-specific
+    implementations.
+
+strategies.py
+    The mechanics of constructing ``Engine`` objects are represented
+    here.  Defines the ``EngineStrategy`` class which represents how
+    to go from arguments specified to the ``create_engine()``
+    function, to a fully constructed ``Engine``, including
+    initialization of connection pooling, dialects, and specific
+    subclasses of ``Engine``.
+
+threadlocal.py
+    The ``TLEngine`` class is defined here, which is a subclass of
+    the generic ``Engine`` and tracks ``Connection`` and
+    ``Transaction`` objects against the identity of the current
+    thread.  This allows certain programming patterns based around
+    the concept of a "thread-local connection" to be possible.
+    The ``TLEngine`` is created by using the "threadlocal" engine
+    strategy in conjunction with the ``create_engine()`` function.
+
+url.py
+    Defines the ``URL`` class which represents the individual
+    components of a string URL passed to ``create_engine()``.  Also
+    defines a basic module-loading strategy for the dialect specifier
+    within a URL.

+def create_engine(*args, **kwargs):
+    """Create a new :class:`.Engine` instance.
+
+    The standard calling form is to send the URL as the
+    first positional argument, usually a string
+    that indicates database dialect and connection arguments::
+
+
+        engine = create_engine("postgresql://scott:tiger@localhost/test")
+
+    Additional keyword arguments may then follow it which
+    establish various options on the resulting :class:`.Engine`
+    and its underlying :class:`.Dialect` and :class:`.Pool`
+    constructs::
+
+        engine = create_engine("mysql://scott:tiger@hostname/dbname",
+                                    encoding='latin1', echo=True)
+
+    The string form of the URL is
+    ``dialect[+driver]://user:password@host/dbname[?key=value..]``, where
+    ``dialect`` is a database name such as ``mysql``, ``oracle``,
+    ``postgresql``, etc., and ``driver`` the name of a DBAPI, such as
+    ``psycopg2``, ``pyodbc``, ``cx_oracle``, etc.  Alternatively,
+    the URL can be an instance of :class:`~sqlalchemy.engine.url.URL`.
+
+    ``**kwargs`` takes a wide variety of options which are routed
+    towards their appropriate components.  Arguments may be specific to
+    the :class:`.Engine`, the underlying :class:`.Dialect`, as well as the
+    :class:`.Pool`.  Specific dialects also accept keyword arguments that
+    are unique to that dialect.   Here, we describe the parameters
+    that are common to most :func:`.create_engine()` usage.
+
+    Once established, the newly resulting :class:`.Engine` will
+    request a connection from the underlying :class:`.Pool` once
+    :meth:`.Engine.connect` is called, or a method which depends on it
+    such as :meth:`.Engine.execute` is invoked.   The :class:`.Pool` in turn
+    will establish the first actual DBAPI connection when this request
+    is received.   The :func:`.create_engine` call itself does **not**
+    establish any actual DBAPI connections directly.
+
+    .. seealso::
+
+        :doc:`/core/engines`
+
+        :doc:`/dialects/index`
+
+        :ref:`connections_toplevel`
+
+    :param case_sensitive=True: if False, result column names
+       will match in a case-insensitive fashion, that is,
+       ``row['SomeColumn']``.
+
+       .. versionchanged:: 0.8
+           By default, result row names match case-sensitively.
+           In version 0.7 and prior, all matches were case-insensitive.
+
+    :param connect_args: a dictionary of options which will be
+        passed directly to the DBAPI's ``connect()`` method as
+        additional keyword arguments.  See the example
+        at :ref:`custom_dbapi_args`.
+
+    :param convert_unicode=False: if set to True, sets
+        the default behavior of ``convert_unicode`` on the
+        :class:`.String` type to ``True``, regardless
+        of a setting of ``False`` on an individual
+        :class:`.String` type, thus causing all :class:`.String`
+        -based columns
+        to accommodate Python ``unicode`` objects.  This flag
+        is useful as an engine-wide setting when using a
+        DBAPI that does not natively support Python
+        ``unicode`` objects and raises an error when
+        one is received (such as pyodbc with FreeTDS).
+
+        See :class:`.String` for further details on
+        what this flag indicates.
+
+    :param creator: a callable which returns a DBAPI connection.
+        This creation function will be passed to the underlying
+        connection pool and will be used to create all new database
+        connections. Usage of this function causes connection
+        parameters specified in the URL argument to be bypassed.
+
+    :param echo=False: if True, the Engine will log all statements
+        as well as a repr() of their parameter lists to the engines
+        logger, which defaults to sys.stdout. The ``echo`` attribute of
+        ``Engine`` can be modified at any time to turn logging on and
+        off. If set to the string ``"debug"``, result rows will be
+        printed to the standard output as well. This flag ultimately
+        controls a Python logger; see :ref:`dbengine_logging` for
+        information on how to configure logging directly.
+
+    :param echo_pool=False: if True, the connection pool will log
+        all checkouts/checkins to the logging stream, which defaults to
+        sys.stdout. This flag ultimately controls a Python logger; see
+        :ref:`dbengine_logging` for information on how to configure logging
+        directly.
+
+    :param encoding: Defaults to ``utf-8``.  This is the string
+        encoding used by SQLAlchemy for string encode/decode
+        operations which occur within SQLAlchemy, **outside of
+        the DBAPI.**  Most modern DBAPIs feature some degree of
+        direct support for Python ``unicode`` objects,
+        what you see in Python 2 as a string of the form
+        ``u'some string'``.  For those scenarios where the
+        DBAPI is detected as not supporting a Python ``unicode``
+        object, this encoding is used to determine the
+        source/destination encoding.  It is **not used**
+        for those cases where the DBAPI handles unicode
+        directly.
+
+        To properly configure a system to accommodate Python
+        ``unicode`` objects, the DBAPI should be
+        configured to handle unicode to the greatest
+        degree as is appropriate - see
+        the notes on unicode pertaining to the specific
+        target database in use at :ref:`dialect_toplevel`.
+
+        Areas where string encoding may need to be accommodated
+        outside of the DBAPI include zero or more of:
+
+        * the values passed to bound parameters, corresponding to
+          the :class:`.Unicode` type or the :class:`.String` type
+          when ``convert_unicode`` is ``True``;
+        * the values returned in result set columns corresponding
+          to the :class:`.Unicode` type or the :class:`.String`
+          type when ``convert_unicode`` is ``True``;
+        * the string SQL statement passed to the DBAPI's
+          ``cursor.execute()`` method;
+        * the string names of the keys in the bound parameter
+          dictionary passed to the DBAPI's ``cursor.execute()``
+          as well as ``cursor.setinputsizes()`` methods;
+        * the string column names retrieved from the DBAPI's
+          ``cursor.description`` attribute.
+
+        When using Python 3, the DBAPI is required to support
+        *all* of the above values as Python ``unicode`` objects,
+        which in Python 3 are just known as ``str``.  In Python 2,
+        the DBAPI does not specify unicode behavior at all,
+        so SQLAlchemy must make decisions for each of the above
+        values on a per-DBAPI basis - implementations are
+        completely inconsistent in their behavior.
+
+    :param execution_options: Dictionary execution options which will
+        be applied to all connections.  See
+        :meth:`~sqlalchemy.engine.Connection.execution_options`
+
+    :param implicit_returning=True: When ``True``, a RETURNING-
+        compatible construct, if available, will be used to
+        fetch newly generated primary key values when a single row
+        INSERT statement is emitted with no existing returning()
+        clause.  This applies to those backends which support RETURNING
+        or a compatible construct, including Postgresql, Firebird, Oracle,
+        Microsoft SQL Server.   Set this to ``False`` to disable
+        the automatic usage of RETURNING.
+
+    :param label_length=None: optional integer value which limits
+        the size of dynamically generated column labels to that many
+        characters. If less than 6, labels are generated as
+        "_(counter)". If ``None``, the value of
+        ``dialect.max_identifier_length`` is used instead.
+
+    :param listeners: A list of one or more
+        :class:`~sqlalchemy.interfaces.PoolListener` objects which will
+        receive connection pool events.
+
+    :param logging_name:  String identifier which will be used within
+        the "name" field of logging records generated within the
+        "sqlalchemy.engine" logger. Defaults to a hexstring of the
+        object's id.
+
+    :param max_overflow=10: the number of connections to allow in
+        connection pool "overflow", that is connections that can be
+        opened above and beyond the pool_size setting, which defaults
+        to five. this is only used with :class:`~sqlalchemy.pool.QueuePool`.
+
+    :param module=None: reference to a Python module object (the module
+        itself, not its string name).  Specifies an alternate DBAPI module to
+        be used by the engine's dialect.  Each sub-dialect references a
+        specific DBAPI which will be imported before first connect.  This
+        parameter causes the import to be bypassed, and the given module to
+        be used instead. Can be used for testing of DBAPIs as well as to
+        inject "mock" DBAPI implementations into the :class:`.Engine`.
+
+    :param pool=None: an already-constructed instance of
+        :class:`~sqlalchemy.pool.Pool`, such as a
+        :class:`~sqlalchemy.pool.QueuePool` instance. If non-None, this
+        pool will be used directly as the underlying connection pool
+        for the engine, bypassing whatever connection parameters are
+        present in the URL argument. For information on constructing
+        connection pools manually, see :ref:`pooling_toplevel`.
+
+    :param poolclass=None: a :class:`~sqlalchemy.pool.Pool`
+        subclass, which will be used to create a connection pool
+        instance using the connection parameters given in the URL. Note
+        this differs from ``pool`` in that you don't actually
+        instantiate the pool in this case, you just indicate what type
+        of pool to be used.
+
+    :param pool_logging_name:  String identifier which will be used within
+       the "name" field of logging records generated within the
+       "sqlalchemy.pool" logger. Defaults to a hexstring of the object's
+       id.
+
+    :param pool_size=5: the number of connections to keep open
+        inside the connection pool. This used with
+        :class:`~sqlalchemy.pool.QueuePool` as
+        well as :class:`~sqlalchemy.pool.SingletonThreadPool`.  With
+        :class:`~sqlalchemy.pool.QueuePool`, a ``pool_size`` setting
+        of 0 indicates no limit; to disable pooling, set ``poolclass`` to
+        :class:`~sqlalchemy.pool.NullPool` instead.
+
+    :param pool_recycle=-1: this setting causes the pool to recycle
+        connections after the given number of seconds has passed. It
+        defaults to -1, or no timeout. For example, setting to 3600
+        means connections will be recycled after one hour. Note that
+        MySQL in particular will disconnect automatically if no
+        activity is detected on a connection for eight hours (although
+        this is configurable with the MySQLDB connection itself and the
+        server configuration as well).
+
+    :param pool_reset_on_return='rollback': set the "reset on return"
+        behavior of the pool, which is whether ``rollback()``,
+        ``commit()``, or nothing is called upon connections
+        being returned to the pool.  See the docstring for
+        ``reset_on_return`` at :class:`.Pool`.
+
+        .. versionadded:: 0.7.6
+
+    :param pool_timeout=30: number of seconds to wait before giving
+        up on getting a connection from the pool. This is only used
+        with :class:`~sqlalchemy.pool.QueuePool`.
+
+    :param strategy='plain': selects alternate engine implementations.
+        Currently available are:
+
+        * the ``threadlocal`` strategy, which is described in
+          :ref:`threadlocal_strategy`;
+        * the ``mock`` strategy, which dispatches all statement
+          execution to a function passed as the argument ``executor``.
+          See `example in the FAQ
+          <http://www.sqlalchemy.org/trac/wiki/FAQ#HowcanIgettheCREATETABLEDROPTABLEoutputasastring>`_.
+
+    :param executor=None: a function taking arguments

+        the same underlying DBAPI connection, but also defines the given
+        execution options which will take effect for a call to
+        :meth:`execute`. As the new :class:`.Connection` references the same

+                                execute(stmt)
+
+        Note that any key/value can be passed to
+        :meth:`.Connection.execution_options`, and it will be stored in the
+        ``_execution_options`` dictionary of the :class:`.Connection`.   It
+        is suitable for usage by end-user schemes to communicate with
+        event listeners, for example.
+
+        The keywords that are currently recognized by SQLAlchemy itself
+        include all those listed under :meth:`.Executable.execution_options`,
+        as well as others that are specific to :class:`.Connection`.
+
+        :param autocommit: Available on: Connection, statement.
+          When True, a COMMIT will be invoked after execution
+          when executed in 'autocommit' mode, i.e. when an explicit
+          transaction is not begun on the connection. Note that DBAPI
+          connections by default are always in a transaction - SQLAlchemy uses
+          rules applied to different kinds of statements to determine if
+          COMMIT will be invoked in order to provide its "autocommit" feature.
+          Typically, all INSERT/UPDATE/DELETE statements as well as
+          CREATE/DROP statements have autocommit behavior enabled; SELECT
+          constructs do not. Use this option when invoking a SELECT or other
+          specific SQL construct where COMMIT is desired (typically when
+          calling stored procedures and such), and an explicit
+          transaction is not in progress.
+
+        :param compiled_cache: Available on: Connection.
+          A dictionary where :class:`.Compiled` objects
+          will be cached when the :class:`.Connection` compiles a clause
+          expression into a :class:`.Compiled` object.
+          It is the user's responsibility to
+          manage the size of this dictionary, which will have keys
+          corresponding to the dialect, clause element, the column
+          names within the VALUES or SET clause of an INSERT or UPDATE,
+          as well as the "batch" mode for an INSERT or UPDATE statement.
+          The format of this dictionary is not guaranteed to stay the
+          same in future releases.
+
+          Note that the ORM makes use of its own "compiled" caches for
+          some operations, including flush operations.  The caching
+          used by the ORM internally supersedes a cache dictionary
+          specified here.
+
+        :param isolation_level: Available on: Connection.
+          Set the transaction isolation level for
+          the lifespan of this connection.   Valid values include
+          those string values accepted by the ``isolation_level``
+          parameter passed to :func:`.create_engine`, and are
+          database specific, including those for :ref:`sqlite_toplevel`,
+          :ref:`postgresql_toplevel` - see those dialect's documentation
+          for further info.
+
+          Note that this option necessarily affects the underlying
+          DBAPI connection for the lifespan of the originating
+          :class:`.Connection`, and is not per-execution. This
+          setting is not removed until the underlying DBAPI connection
+          is returned to the connection pool, i.e.
+          the :meth:`.Connection.close` method is called.
+
+        :param no_parameters: When ``True``, if the final parameter
+          list or dictionary is totally empty, will invoke the
+          statement on the cursor as ``cursor.execute(statement)``,
+          not passing the parameter collection at all.
+          Some DBAPIs such as psycopg2 and mysql-python consider
+          percent signs as significant only when parameters are
+          present; this option allows code to generate SQL
+          containing percent signs (and possibly other characters)
+          that is neutral regarding whether it's executed by the DBAPI
+          or piped into a script that's later invoked by
+          command line tools.
+
+          .. versionadded:: 0.7.6

+          of many DBAPIs.  The flag is currently understood only by the

+class Dialect(object):
+    """Define the behavior of a specific database and DB-API combination.
+
+    Any aspect of metadata definition, SQL query generation,
+    execution, result-set handling, or anything else which varies
+    between databases is defined under the general category of the
+    Dialect.  The Dialect acts as a factory for other
+    database-specific object implementations including
+    ExecutionContext, Compiled, DefaultGenerator, and TypeEngine.
+
+    All Dialects implement the following attributes:
+
+    name
+      identifying name for the dialect from a DBAPI-neutral point of view
+      (i.e. 'sqlite')
+
+    driver
+      identifying name for the dialect's DBAPI
+
+    positional
+      True if the paramstyle for this Dialect is positional.
+
+    paramstyle
+      the paramstyle to be used (some DB-APIs support multiple
+      paramstyles).
+
+    convert_unicode
+      True if Unicode conversion should be applied to all ``str``
+      types.
+
+    encoding
+      type of encoding to use for unicode, usually defaults to
+      'utf-8'.
+
+    statement_compiler
+      a :class:`.Compiled` class used to compile SQL statements
+
+    ddl_compiler
+      a :class:`.Compiled` class used to compile DDL statements
+
+    server_version_info
+      a tuple containing a version number for the DB backend in use.
+      This value is only available for supporting dialects, and is
+      typically populated during the initial connection to the database.
+
+    default_schema_name
+     the name of the default schema.  This value is only available for
+     supporting dialects, and is typically populated during the
+     initial connection to the database.
+
+    execution_ctx_cls
+      a :class:`.ExecutionContext` class used to handle statement execution
+
+    execute_sequence_format
+      either the 'tuple' or 'list' type, depending on what cursor.execute()
+      accepts for the second argument (they vary).
+
+    preparer
+      a :class:`~sqlalchemy.sql.compiler.IdentifierPreparer` class used to
+      quote identifiers.
+
+    supports_alter
+      ``True`` if the database supports ``ALTER TABLE``.
+
+    max_identifier_length
+      The maximum length of identifier names.
+
+    supports_unicode_statements
+      Indicate whether the DB-API can receive SQL statements as Python
+      unicode strings
+
+    supports_unicode_binds
+      Indicate whether the DB-API can receive string bind parameters
+      as Python unicode strings
+
+    supports_sane_rowcount
+      Indicate whether the dialect properly implements rowcount for
+      ``UPDATE`` and ``DELETE`` statements.
+
+    supports_sane_multi_rowcount
+      Indicate whether the dialect properly implements rowcount for
+      ``UPDATE`` and ``DELETE`` statements when executed via
+      executemany.
+
+    preexecute_autoincrement_sequences
+      True if 'implicit' primary key functions must be executed separately
+      in order to get their value.   This is currently oriented towards
+      Postgresql.
+
+    implicit_returning
+      use RETURNING or equivalent during INSERT execution in order to load
+      newly generated primary keys and other column defaults in one execution,
+      which are then available via inserted_primary_key.
+      If an insert statement has returning() specified explicitly,
+      the "implicit" functionality is not used and inserted_primary_key
+      will not be available.
+
+    dbapi_type_map
+      A mapping of DB-API type objects present in this Dialect's
+      DB-API implementation mapped to TypeEngine implementations used
+      by the dialect.
+
+      This is used to apply types to result sets based on the DB-API
+      types present in cursor.description; it only takes effect for
+      result sets against textual statements where no explicit
+      typemap was present.
+
+    colspecs
+      A dictionary of TypeEngine classes from sqlalchemy.types mapped
+      to subclasses that are specific to the dialect class.  This
+      dictionary is class-level only and is not accessed from the
+      dialect instance itself.
+
+    supports_default_values
+      Indicates if the construct ``INSERT INTO tablename DEFAULT
+      VALUES`` is supported
+
+    supports_sequences
+      Indicates if the dialect supports CREATE SEQUENCE or similar.
+
+    sequences_optional
+      If True, indicates if the "optional" flag on the Sequence() construct
+      should signal to not generate a CREATE SEQUENCE. Applies only to
+      dialects that support sequences. Currently used only to allow Postgresql
+      SERIAL to be used on a column that specifies Sequence() for usage on
+      other backends.
+
+    supports_native_enum
+      Indicates if the dialect supports a native ENUM construct.
+      This will prevent types.Enum from generating a CHECK
+      constraint when that type is used.
+
+    supports_native_boolean
+      Indicates if the dialect supports a native boolean construct.
+      This will prevent types.Boolean from generating a CHECK
+      constraint when that type is used.

+"""Provides an abstraction for obtaining database schema information.
+
+Usage Notes:
+
+Here are some general conventions when accessing the low level inspector
+methods such as get_table_names, get_columns, etc.
+
+1. Inspector methods return lists of dicts in most cases for the following
+   reasons:
+
+   * They're both standard types that can be serialized.
+   * Using a dict instead of a tuple allows easy expansion of attributes.
+   * Using a list for the outer structure maintains order and is easy to work
+     with (e.g. list comprehension [d['name'] for d in cols]).
+
+2. Records that contain a name, such as the column name in a column record
+   use the key 'name'. So for most return values, each record will have a
+   'name' attribute..

+"""Attribute implementation for _Dispatch classes.
+
+The various listener targets for a particular event class are represented
+as attributes, which refer to collections of listeners to be fired off.
+These collections can exist at the class level as well as at the instance
+level.  An event is fired off using code like this::
+
+    some_object.dispatch.first_connect(arg1, arg2)
+
+Above, ``some_object.dispatch`` would be an instance of ``_Dispatch`` and
+``first_connect`` is typically an instance of ``_ListenerCollection``
+if event listeners are present, or ``_EmptyListener`` if none are present.
+
+The attribute mechanics here spend effort trying to ensure listener functions
+are available with a minimum of function call overhead, that unnecessary
+objects aren't created (i.e. many empty per-instance listener collections),
+as well as that everything is garbage collectable when owning references are
+lost.  Other features such as "propagation" of listener functions across
+many ``_Dispatch`` instances, "joining" of multiple ``_Dispatch`` instances,
+as well as support for subclass propagation (e.g. events assigned to
+``Pool`` vs. ``QueuePool``) are all implemented here.

+    subclasses, including :class:`.MetaData`, :class:`.Table`,
+    :class:`.Column`.
+
+    :class:`.MetaData` and :class:`.Table` support events
+    specifically regarding when CREATE and DROP
+    DDL is emitted to the database.
+
+    Attachment events are also provided to customize

+    with a parent, such as, when a :class:`.Column` is associated
+    with its :class:`.Table`, when a :class:`.ForeignKeyConstraint`
+    is associated with a :class:`.Table`, etc.

+
+        event.listen(some_table, "after_create", after_create)
+
+    DDL events integrate closely with the

+    of DDL clause constructs, which are themselves appropriate

+

+        and new calling scenarios at *any time*.  Code which uses this
+        event must expect new calling patterns to be present in minor
+        releases.
+
+        To support the wide variety of members that correspond to an exception,
+        as well as to allow extensibility of the event without backwards
+        incompatibility, the sole argument received is an instance of
+        :class:`.ExceptionContext`.   This object contains data members
+        representing detail about the exception.
+
+        Use cases supported by this hook include:
+
+        * read-only, low-level exception handling for logging and
+          debugging purposes
+        * exception re-writing
+
+        The hook is called while the cursor from the failed operation
+        (if any) is still open and accessible.   Special cleanup operations
+        can be called on this cursor; SQLAlchemy will attempt to close
+        this cursor subsequent to this hook being invoked.  If the connection
+        is in "autocommit" mode, the transaction also remains open within
+        the scope of this hook; the rollback of the per-statement transaction
+        also occurs after the hook is called.
+
+        The user-defined event handler has two options for replacing
+        the SQLAlchemy-constructed exception into one that is user
+        defined.   It can either raise this new exception directly, in
+        which case all further event listeners are bypassed and the
+        exception will be raised, after appropriate cleanup as taken
+        place::
+
+            @event.listens_for(Engine, "handle_error")
+            def handle_exception(context):
+                if isinstance(context.original_exception,
+                    psycopg2.OperationalError) and \\
+                    "failed" in str(context.original_exception):
+                    raise MySpecialException("failed operation")
+
+        Alternatively, a "chained" style of event handling can be
+        used, by configuring the handler with the ``retval=True``
+        modifier and returning the new exception instance from the
+        function.  In this case, event handling will continue onto the
+        next handler.   The "chained" exception is available using
+        :attr:`.ExceptionContext.chained_exception`::
+
+            @event.listens_for(Engine, "handle_error", retval=True)
+            def handle_exception(context):
+                if context.chained_exception is not None and \\
+                    "special" in context.chained_exception.message:
+                    return MySpecialException("failed",
+                        cause=context.chained_exception)
+
+        Handlers that return ``None`` may remain within this chain; the
+        last non-``None`` return value is the one that continues to be
+        passed to the next handler.
+
+        When a custom exception is raised or returned, SQLAlchemy raises
+        this new exception as-is, it is not wrapped by any SQLAlchemy
+        object.  If the exception is not a subclass of
+        :class:`sqlalchemy.exc.StatementError`,
+        certain features may not be available; currently this includes
+        the ORM's feature of adding a detail hint about "autoflush" to

+
+    Implements a Python property representing a relationship as a collection
+    of simpler values, or a scalar value.  The proxied property will mimic
+    the collection type of the target (list, dict or set), or, in the case of
+    a one to one relationship, a simple scalar value.
+
+    :param target_collection: Name of the attribute we'll proxy to.
+      This attribute is typically mapped by
+      :func:`~sqlalchemy.orm.relationship` to link to a target collection, but
+      can also be a many-to-one or non-scalar relationship.
+
+    :param attr: Attribute on the associated instance or instances we'll
+      proxy for.
+
+      For example, given a target collection of [obj1, obj2], a list created

+
+      If you want to construct instances differently, supply a *creator*
+      function that takes arguments as above and returns instances.
+
+      For scalar relationships, creator() will be called if the target is None.
+      If the target is present, set operations are proxied to setattr() on the
+      associated object.
+
+      If you have an associated object with multiple attributes, you may set
+      up multiple association proxies mapping to different attributes.  See

+"""Define an extension to the :mod:`sqlalchemy.ext.declarative` system
+which automatically generates mapped classes and relationships from a database
+schema, typically though not necessarily one which is reflected.
+
+.. versionadded:: 0.9.1 Added :mod:`sqlalchemy.ext.automap`.
+
+.. note::
+
+    The :mod:`sqlalchemy.ext.automap` extension should be considered
+    **experimental** as of 0.9.1.   Featureset and API stability is
+    not guaranteed at this time.
+
+It is hoped that the :class:`.AutomapBase` system provides a quick
+and modernized solution to the problem that the very famous
+`SQLSoup <https://sqlsoup.readthedocs.org/en/latest/>`_
+also tries to solve, that of generating a quick and rudimentary object
+model from an existing database on the fly.  By addressing the issue strictly
+at the mapper configuration level, and integrating fully with existing
+Declarative class techniques, :class:`.AutomapBase` seeks to provide
+a well-integrated approach to the issue of expediently auto-generating ad-hoc
+mappings.
+
+
+Basic Use
+=========
+
+The simplest usage is to reflect an existing database into a new model.
+We create a new :class:`.AutomapBase` class in a similar manner as to how
+we create a declarative base class, using :func:`.automap_base`.
+We then call :meth:`.AutomapBase.prepare` on the resulting base class,
+asking it to reflect the schema and produce mappings::
+
+    from sqlalchemy.ext.automap import automap_base
+    from sqlalchemy.orm import Session
+    from sqlalchemy import create_engine
+
+    Base = automap_base()
+
+    # engine, suppose it has two tables 'user' and 'address' set up
+    engine = create_engine("sqlite:///mydatabase.db")
+
+    # reflect the tables
+    Base.prepare(engine, reflect=True)
+
+    # mapped classes are now created with names by default
+    # matching that of the table name.
+    User = Base.classes.user
+    Address = Base.classes.address
+
+    session = Session(engine)
+
+    # rudimentary relationships are produced
+    session.add(Address(email_address="foo@bar.com", user=User(name="foo")))
+    session.commit()
+
+    # collection-based relationships are by default named
+    # "<classname>_collection"
+    print (u1.address_collection)
+
+Above, calling :meth:`.AutomapBase.prepare` while passing along the
+:paramref:`.AutomapBase.prepare.reflect` parameter indicates that the
+:meth:`.MetaData.reflect` method will be called on this declarative base
+classes' :class:`.MetaData` collection; then, each viable
+:class:`.Table` within the :class:`.MetaData` will get a new mapped class
+generated automatically.  The :class:`.ForeignKeyConstraint` objects which
+link the various tables together will be used to produce new, bidirectional
+:func:`.relationship` objects between classes.   The classes and relationships
+follow along a default naming scheme that we can customize.  At this point,
+our basic mapping consisting of related ``User`` and ``Address`` classes is
+ready to use in the traditional way.
+
+Generating Mappings from an Existing MetaData
+=============================================
+
+We can pass a pre-declared :class:`.MetaData` object to :func:`.automap_base`.
+This object can be constructed in any way, including programmatically, from
+a serialized file, or from itself being reflected using
+:meth:`.MetaData.reflect`.  Below we illustrate a combination of reflection and
+explicit table declaration::
+
+    from sqlalchemy import create_engine, MetaData, Table, Column, ForeignKey
+    engine = create_engine("sqlite:///mydatabase.db")
+
+    # produce our own MetaData object
+    metadata = MetaData()
+
+    # we can reflect it ourselves from a database, using options
+    # such as 'only' to limit what tables we look at...
+    metadata.reflect(engine, only=['user', 'address'])
+
+    # ... or just define our own Table objects with it (or combine both)
+    Table('user_order', metadata,
+                    Column('id', Integer, primary_key=True),
+                    Column('user_id', ForeignKey('user.id'))
+                )
+
+    # we can then produce a set of mappings from this MetaData.
+    Base = automap_base(metadata=metadata)
+
+    # calling prepare() just sets up mapped classes and relationships.
+    Base.prepare()
+
+    # mapped classes are ready
+    User, Address, Order = Base.classes.user, Base.classes.address,\
+        Base.classes.user_order
+
+Specifying Classes Explcitly
+============================
+
+The :mod:`.sqlalchemy.ext.automap` extension allows classes to be defined
+explicitly, in a way similar to that of the :class:`.DeferredReflection` class.
+Classes that extend from :class:`.AutomapBase` act like regular declarative
+classes, but are not immediately mapped after their construction, and are
+instead mapped when we call :meth:`.AutomapBase.prepare`.  The
+:meth:`.AutomapBase.prepare` method will make use of the classes we've
+established based on the table name we use.  If our schema contains tables
+``user`` and ``address``, we can define one or both of the classes to be used::
+
+    from sqlalchemy.ext.automap import automap_base
+    from sqlalchemy import create_engine
+
+    # automap base
+    Base = automap_base()
+
+    # pre-declare User for the 'user' table
+    class User(Base):
+        __tablename__ = 'user'
+
+        # override schema elements like Columns
+        user_name = Column('name', String)
+
+        # override relationships too, if desired.
+        # we must use the same name that automap would use for the
+        # relationship, and also must refer to the class name that automap will
+        # generate for "address"
+        address_collection = relationship("address", collection_class=set)
+
+    # reflect
+    engine = create_engine("sqlite:///mydatabase.db")
+    Base.prepare(engine, reflect=True)
+
+    # we still have Address generated from the tablename "address",
+    # but User is the same as Base.classes.User now
+
+    Address = Base.classes.address
+
+    u1 = session.query(User).first()
+    print (u1.address_collection)
+
+    # the backref is still there:
+    a1 = session.query(Address).first()
+    print (a1.user)
+
+Above, one of the more intricate details is that we illustrated overriding
+one of the :func:`.relationship` objects that automap would have created.
+To do this, we needed to make sure the names match up with what automap
+would normally generate, in that the relationship name would be
+``User.address_collection`` and the name of the class referred to, from
+automap's perspective, is called ``address``, even though we are referring to
+it as ``Address`` within our usage of this class.
+
+Overriding Naming Schemes
+=========================
+
+:mod:`.sqlalchemy.ext.automap` is tasked with producing mapped classes and
+relationship names based on a schema, which means it has decision points in how
+these names are determined.  These three decision points are provided using
+functions which can be passed to the :meth:`.AutomapBase.prepare` method, and
+are known as :func:`.classname_for_table`,
+:func:`.name_for_scalar_relationship`,
+and :func:`.name_for_collection_relationship`.  Any or all of these
+functions are provided as in the example below, where we use a "camel case"
+scheme for class names and a "pluralizer" for collection names using the
+`Inflect <https://pypi.python.org/pypi/inflect>`_ package::
+
+    import re
+    import inflect
+
+    def camelize_classname(base, tablename, table):
+        "Produce a 'camelized' class name, e.g. "
+        "'words_and_underscores' -> 'WordsAndUnderscores'"
+
+        return str(tablename[0].upper() + \\
+                re.sub(r'_(\w)', lambda m: m.group(1).upper(), tablename[1:]))
+
+    _pluralizer = inflect.engine()
+    def pluralize_collection(base, local_cls, referred_cls, constraint):
+        "Produce an 'uncamelized', 'pluralized' class name, e.g. "
+        "'SomeTerm' -> 'some_terms'"
+
+        referred_name = referred_cls.__name__
+        uncamelized = referred_name[0].lower() + \\
+                        re.sub(r'\W',
+                                lambda m: "_%s" % m.group(0).lower(),
+                                referred_name[1:])
+        pluralized = _pluralizer.plural(uncamelized)
+        return pluralized
+
+    from sqlalchemy.ext.automap import automap_base
+
+    Base = automap_base()
+
+    engine = create_engine("sqlite:///mydatabase.db")
+
+    Base.prepare(engine, reflect=True,
+                classname_for_table=camelize_classname,
+                name_for_collection_relationship=pluralize_collection
+        )
+
+From the above mapping, we would now have classes ``User`` and ``Address``,
+where the collection from ``User`` to ``Address`` is called
+``User.addresses``::
+
+    User, Address = Base.classes.User, Base.classes.Address
+
+    u1 = User(addresses=[Address(email="foo@bar.com")])
+
+Relationship Detection
+======================
+
+The vast majority of what automap accomplishes is the generation of
+:func:`.relationship` structures based on foreign keys.  The mechanism
+by which this works for many-to-one and one-to-many relationships is as
+follows:
+
+1. A given :class:`.Table`, known to be mapped to a particular class,
+   is examined for :class:`.ForeignKeyConstraint` objects.
+
+2. From each :class:`.ForeignKeyConstraint`, the remote :class:`.Table`
+   object present is matched up to the class to which it is to be mapped,
+   if any, else it is skipped.
+
+3. As the :class:`.ForeignKeyConstraint` we are examining corresponds to a
+   reference from the immediate mapped class,  the relationship will be set up
+   as a many-to-one referring to the referred class; a corresponding
+   one-to-many backref will be created on the referred class referring
+   to this class.
+
+4. The names of the relationships are determined using the
+   :paramref:`.AutomapBase.prepare.name_for_scalar_relationship` and
+   :paramref:`.AutomapBase.prepare.name_for_collection_relationship`
+   callable functions.  It is important to note that the default relationship
+   naming derives the name from the **the actual class name**.  If you've
+   given a particular class an explicit name by declaring it, or specified an
+   alternate class naming scheme, that's the name from which the relationship
+   name will be derived.
+
+5. The classes are inspected for an existing mapped property matching these
+   names.  If one is detected on one side, but none on the other side,
+   :class:`.AutomapBase` attempts to create a relationship on the missing side,
+   then uses the :paramref:`.relationship.back_populates` parameter in order to
+   point the new relationship to the other side.
+
+6. In the usual case where no relationship is on either side,
+   :meth:`.AutomapBase.prepare` produces a :func:`.relationship` on the
+   "many-to-one" side and matches it to the other using the
+   :paramref:`.relationship.backref` parameter.
+
+7. Production of the :func:`.relationship` and optionally the :func:`.backref`
+   is handed off to the :paramref:`.AutomapBase.prepare.generate_relationship`
+   function, which can be supplied by the end-user in order to augment
+   the arguments passed to :func:`.relationship` or :func:`.backref` or to
+   make use of custom implementations of these functions.
+
+Custom Relationship Arguments
+-----------------------------
+
+The :paramref:`.AutomapBase.prepare.generate_relationship` hook can be used
+to add parameters to relationships.  For most cases, we can make use of the
+existing :func:`.automap.generate_relationship` function to return
+the object, after augmenting the given keyword dictionary with our own
+arguments.
+
+Below is an illustration of how to send
+:paramref:`.relationship.cascade` and
+:paramref:`.relationship.passive_deletes`
+options along to all one-to-many relationships::
+
+    from sqlalchemy.ext.automap import generate_relationship
+
+    def _gen_relationship(base, direction, return_fn,
+                                    attrname, local_cls, referred_cls, **kw):
+        if direction is interfaces.ONETOMANY:
+            kw['cascade'] = 'all, delete-orphan'
+            kw['passive_deletes'] = True
+        # make use of the built-in function to actually return
+        # the result.
+        return generate_relationship(base, direction, return_fn,
+                                     attrname, local_cls, referred_cls, **kw)
+
+    from sqlalchemy.ext.automap import automap_base
+    from sqlalchemy import create_engine
+
+    # automap base

+
+Many-to-Many relationships
+--------------------------
+
+:mod:`.sqlalchemy.ext.automap` will generate many-to-many relationships, e.g.
+those which contain a ``secondary`` argument.  The process for producing these
+is as follows:
+
+1. A given :class:`.Table` is examined for :class:`.ForeignKeyConstraint`
+   objects, before any mapped class has been assigned to it.
+
+2. If the table contains two and exactly two :class:`.ForeignKeyConstraint`
+   objects, and all columns within this table are members of these two
+   :class:`.ForeignKeyConstraint` objects, the table is assumed to be a
+   "secondary" table, and will **not be mapped directly**.
+
+3. The two (or one, for self-referential) external tables to which the
+   :class:`.Table` refers to are matched to the classes to which they will be
+   mapped, if any.
+
+4. If mapped classes for both sides are located, a many-to-many bi-directional
+   :func:`.relationship` / :func:`.backref` pair is created between the two
+   classes.
+
+5. The override logic for many-to-many works the same as that of one-to-many/
+   many-to-one; the :func:`.generate_relationship` function is called upon
+   to generate the strucures and existing attributes will be maintained.
+
+Relationships with Inheritance
+------------------------------
+
+:mod:`.sqlalchemy.ext.automap` will not generate any relationships between
+two classes that are in an inheritance relationship.   That is, with two
+classes given as follows::
+
+    class Employee(Base):
+        __tablename__ = 'employee'
+        id = Column(Integer, primary_key=True)
+        type = Column(String(50))
+        __mapper_args__ = {
+             'polymorphic_identity':'employee', 'polymorphic_on': type
+        }
+
+    class Engineer(Employee):
+        __tablename__ = 'engineer'
+        id = Column(Integer, ForeignKey('employee.id'), primary_key=True)
+        __mapper_args__ = {
+            'polymorphic_identity':'engineer',
+        }
+
+The foreign key from ``Engineer`` to ``Employee`` is used not for a
+relationship, but to establish joined inheritance between the two classes.
+
+Note that this means automap will not generate *any* relationships
+for foreign keys that link from a subclass to a superclass.  If a mapping
+has actual relationships from subclass to superclass as well, those
+need to be explicit.  Below, as we have two separate foreign keys
+from ``Engineer`` to ``Employee``, we need to set up both the relationship
+we want as well as the ``inherit_condition``, as these are not things
+SQLAlchemy can guess::
+
+    class Employee(Base):
+        __tablename__ = 'employee'
+        id = Column(Integer, primary_key=True)
+        type = Column(String(50))
+
+        __mapper_args__ = {
+            'polymorphic_identity':'employee', 'polymorphic_on':type
+        }
+
+    class Engineer(Employee):
+        __tablename__ = 'engineer'
+        id = Column(Integer, ForeignKey('employee.id'), primary_key=True)
+        favorite_employee_id = Column(Integer, ForeignKey('employee.id'))
+
+        favorite_employee = relationship(Employee,
+                                         foreign_keys=favorite_employee_id)
+
+        __mapper_args__ = {
+            'polymorphic_identity':'engineer',
+            'inherit_condition': id == Employee.id
+        }
+
+Handling Simple Naming Conflicts
+--------------------------------
+
+In the case of naming conflicts during mapping, override any of
+:func:`.classname_for_table`, :func:`.name_for_scalar_relationship`,
+and :func:`.name_for_collection_relationship` as needed.  For example, if
+automap is attempting to name a many-to-one relationship the same as an
+existing column, an alternate convention can be conditionally selected.  Given
+a schema:
+
+.. sourcecode:: sql
+
+    CREATE TABLE table_a (
+        id INTEGER PRIMARY KEY
+    );
+
+    CREATE TABLE table_b (
+        id INTEGER PRIMARY KEY,
+        table_a INTEGER,
+        FOREIGN KEY(table_a) REFERENCES table_a(id)
+    );
+
+The above schema will first automap the ``table_a`` table as a class named
+``table_a``; it will then automap a relationship onto the class for ``table_b``
+with the same name as this related class, e.g. ``table_a``.  This
+relationship name conflicts with the mapping column ``table_b.table_a``,
+and will emit an error on mapping.
+
+We can resolve this conflict by using an underscore as follows::
+
+    def name_for_scalar_relationship(base, local_cls, referred_cls, constraint):
+        name = referred_cls.__name__.lower()
+        local_table = local_cls.__table__
+        if name in local_table.columns:
+            newname = name + "_"
+            warnings.warn(
+                "Already detected name %s present.  using %s" %
+                (name, newname))
+            return newname
+        return name
+
+
+    Base.prepare(engine, reflect=True,
+        name_for_scalar_relationship=name_for_scalar_relationship)
+
+Alternatively, we can change the name on the column side.   The columns
+that are mapped can be modified using the technique described at
+:ref:`mapper_column_distinct_names`, by assigning the column explicitly
+to a new name::
+
+    Base = automap_base()
+
+    class TableB(Base):
+        __tablename__ = 'table_b'
+        _table_a = Column('table_a', ForeignKey('table_a.id'))
+
+    Base.prepare(engine, reflect=True)
+
+
+Using Automap with Explicit Declarations
+========================================
+
+As noted previously, automap has no dependency on reflection, and can make
+use of any collection of :class:`.Table` objects within a :class:`.MetaData`
+collection.  From this, it follows that automap can also be used
+generate missing relationships given an otherwise complete model that fully
+defines table metadata::
+
+    from sqlalchemy.ext.automap import automap_base
+    from sqlalchemy import Column, Integer, String, ForeignKey
+
+    Base = automap_base()
+
+    class User(Base):
+        __tablename__ = 'user'
+
+        id = Column(Integer, primary_key=True)
+        name = Column(String)
+
+    class Address(Base):
+        __tablename__ = 'address'
+
+        id = Column(Integer, primary_key=True)
+        email = Column(String)
+        user_id = Column(ForeignKey('user.id'))
+
+    # produce relationships
+    Base.prepare()
+
+    # mapping is complete, with "address_collection" and
+    # "user" relationships
+    a1 = Address(email='u1')
+    a2 = Address(email='u2')
+    u1 = User(address_collection=[a1, a2])
+    assert a1.user is u1
+
+Above, given mostly complete ``User`` and ``Address`` mappings, the
+:class:`.ForeignKey` which we defined on ``Address.user_id`` allowed a
+bidirectional relationship pair ``Address.user`` and
+``User.address_collection`` to be generated on the mapped classes.
+
+Note that when subclassing :class:`.AutomapBase`,
+the :meth:`.AutomapBase.prepare` method is required; if not called, the classes
+we've declared are in an un-mapped state.

+"""Provides an API for creation of custom ClauseElements and compilers.
+
+Synopsis
+========
+
+Usage involves the creation of one or more
+:class:`~sqlalchemy.sql.expression.ClauseElement` subclasses and one or
+more callables defining its compilation::
+
+    from sqlalchemy.ext.compiler import compiles
+    from sqlalchemy.sql.expression import ColumnClause
+
+    class MyColumn(ColumnClause):
+        pass
+
+    @compiles(MyColumn)
+    def compile_mycolumn(element, compiler, **kw):
+        return "[%s]" % element.name
+
+Above, ``MyColumn`` extends :class:`~sqlalchemy.sql.expression.ColumnClause`,
+the base expression element for named column objects. The ``compiles``
+decorator registers itself with the ``MyColumn`` class so that it is invoked
+when the object is compiled to a string::
+
+    from sqlalchemy import select
+
+    s = select([MyColumn('x'), MyColumn('y')])
+    print str(s)
+
+Produces::
+
+    SELECT [x], [y]
+
+Dialect-specific compilation rules
+==================================
+
+Compilers can also be made dialect-specific. The appropriate compiler will be
+invoked for the dialect in use::
+
+    from sqlalchemy.schema import DDLElement
+
+    class AlterColumn(DDLElement):
+
+        def __init__(self, column, cmd):
+            self.column = column
+            self.cmd = cmd
+
+    @compiles(AlterColumn)
+    def visit_alter_column(element, compiler, **kw):
+        return "ALTER COLUMN %s ..." % element.column.name
+
+    @compiles(AlterColumn, 'postgresql')
+    def visit_alter_column(element, compiler, **kw):
+        return "ALTER TABLE %s ALTER COLUMN %s ..." % (element.table.name,
+                                                       element.column.name)
+
+The second ``visit_alter_table`` will be invoked when any ``postgresql``
+dialect is used.
+
+Compiling sub-elements of a custom expression construct
+=======================================================
+
+The ``compiler`` argument is the
+:class:`~sqlalchemy.engine.interfaces.Compiled` object in use. This object
+can be inspected for any information about the in-progress compilation,
+including ``compiler.dialect``, ``compiler.statement`` etc. The
+:class:`~sqlalchemy.sql.compiler.SQLCompiler` and
+:class:`~sqlalchemy.sql.compiler.DDLCompiler` both include a ``process()``
+method which can be used for compilation of embedded attributes::
+
+    from sqlalchemy.sql.expression import Executable, ClauseElement
+
+    class InsertFromSelect(Executable, ClauseElement):
+        def __init__(self, table, select):
+            self.table = table
+            self.select = select
+
+    @compiles(InsertFromSelect)
+    def visit_insert_from_select(element, compiler, **kw):
+        return "INSERT INTO %s (%s)" % (
+            compiler.process(element.table, asfrom=True),
+            compiler.process(element.select)
+        )
+
+    insert = InsertFromSelect(t1, select([t1]).where(t1.c.x>5))
+    print insert
+
+Produces::
+
+    "INSERT INTO mytable (SELECT mytable.x, mytable.y, mytable.z
+                          FROM mytable WHERE mytable.x > :x_1)"
+
+.. note::
+
+    The above ``InsertFromSelect`` construct is only an example, this actual
+    functionality is already available using the
+    :meth:`.Insert.from_select` method.
+
+.. note::
+
+   The above ``InsertFromSelect`` construct probably wants to have "autocommit"
+   enabled.  See :ref:`enabling_compiled_autocommit` for this step.
+
+Cross Compiling between SQL and DDL compilers
+---------------------------------------------
+
+SQL and DDL constructs are each compiled using different base compilers -
+``SQLCompiler`` and ``DDLCompiler``.   A common need is to access the
+compilation rules of SQL expressions from within a DDL expression. The
+``DDLCompiler`` includes an accessor ``sql_compiler`` for this reason, such as
+below where we generate a CHECK constraint that embeds a SQL expression::
+
+    @compiles(MyConstraint)
+    def compile_my_constraint(constraint, ddlcompiler, **kw):
+        return "CONSTRAINT %s CHECK (%s)" % (
+            constraint.name,
+            ddlcompiler.sql_compiler.process(constraint.expression)
+        )
+
+.. _enabling_compiled_autocommit:
+
+Enabling Autocommit on a Construct
+==================================
+
+Recall from the section :ref:`autocommit` that the :class:`.Engine`, when
+asked to execute a construct in the absence of a user-defined transaction,
+detects if the given construct represents DML or DDL, that is, a data
+modification or data definition statement, which requires (or may require,
+in the case of DDL) that the transaction generated by the DBAPI be committed
+(recall that DBAPI always has a transaction going on regardless of what
+SQLAlchemy does).   Checking for this is actually accomplished by checking for
+the "autocommit" execution option on the construct.    When building a
+construct like an INSERT derivation, a new DDL type, or perhaps a stored
+procedure that alters data, the "autocommit" option needs to be set in order
+for the statement to function with "connectionless" execution
+(as described in :ref:`dbengine_implicit`).
+
+Currently a quick way to do this is to subclass :class:`.Executable`, then
+add the "autocommit" flag to the ``_execution_options`` dictionary (note this
+is a "frozen" dictionary which supplies a generative ``union()`` method)::
+
+    from sqlalchemy.sql.expression import Executable, ClauseElement
+
+    class MyInsertThing(Executable, ClauseElement):
+        _execution_options = \\
+            Executable._execution_options.union({'autocommit': True})
+
+More succinctly, if the construct is truly similar to an INSERT, UPDATE, or
+DELETE, :class:`.UpdateBase` can be used, which already is a subclass
+of :class:`.Executable`, :class:`.ClauseElement` and includes the
+``autocommit`` flag::
+
+    from sqlalchemy.sql.expression import UpdateBase
+
+    class MyInsertThing(UpdateBase):
+        def __init__(self, ...):
+            ...
+
+
+
+
+DDL elements that subclass :class:`.DDLElement` already have the
+"autocommit" flag turned on.
+
+
+
+
+Changing the default compilation of existing constructs
+=======================================================
+
+The compiler extension applies just as well to the existing constructs.  When
+overriding the compilation of a built in SQL construct, the @compiles
+decorator is invoked upon the appropriate class (be sure to use the class,
+i.e. ``Insert`` or ``Select``, instead of the creation function such
+as ``insert()`` or ``select()``).
+
+Within the new compilation function, to get at the "original" compilation
+routine, use the appropriate visit_XXX method - this
+because compiler.process() will call upon the overriding routine and cause
+an endless loop.   Such as, to add "prefix" to all insert statements::
+
+    from sqlalchemy.sql.expression import Insert
+
+    @compiles(Insert)
+    def prefix_inserts(insert, compiler, **kw):
+        return compiler.visit_insert(insert.prefix_with("some prefix"), **kw)
+
+The above compiler will prefix all INSERT statements with "some prefix" when
+compiled.
+
+.. _type_compilation_extension:
+
+Changing Compilation of Types
+=============================
+
+``compiler`` works for types, too, such as below where we implement the
+MS-SQL specific 'max' keyword for ``String``/``VARCHAR``::
+
+    @compiles(String, 'mssql')
+    @compiles(VARCHAR, 'mssql')
+    def compile_varchar(element, compiler, **kw):
+        if element.length == 'max':
+            return "VARCHAR('max')"
+        else:
+            return compiler.visit_VARCHAR(element, **kw)
+
+    foo = Table('foo', metadata,
+        Column('data', VARCHAR('max'))
+    )
+
+Subclassing Guidelines
+======================
+
+A big part of using the compiler extension is subclassing SQLAlchemy
+expression constructs. To make this easier, the expression and
+schema packages feature a set of "bases" intended for common tasks.
+A synopsis is as follows:
+
+* :class:`~sqlalchemy.sql.expression.ClauseElement` - This is the root
+  expression class. Any SQL expression can be derived from this base, and is
+  probably the best choice for longer constructs such as specialized INSERT
+  statements.
+
+* :class:`~sqlalchemy.sql.expression.ColumnElement` - The root of all
+  "column-like" elements. Anything that you'd place in the "columns" clause of
+  a SELECT statement (as well as order by and group by) can derive from this -
+  the object will automatically have Python "comparison" behavior.
+
+  :class:`~sqlalchemy.sql.expression.ColumnElement` classes want to have a
+  ``type`` member which is expression's return type.  This can be established
+  at the instance level in the constructor, or at the class level if its
+  generally constant::
+
+      class timestamp(ColumnElement):
+          type = TIMESTAMP()
+
+* :class:`~sqlalchemy.sql.functions.FunctionElement` - This is a hybrid of a
+  ``ColumnElement`` and a "from clause" like object, and represents a SQL
+  function or stored procedure type of call. Since most databases support
+  statements along the line of "SELECT FROM <some function>"
+  ``FunctionElement`` adds in the ability to be used in the FROM clause of a
+  ``select()`` construct::
+
+      from sqlalchemy.sql.expression import FunctionElement
+
+      class coalesce(FunctionElement):
+          name = 'coalesce'
+

+      @compiles(coalesce, 'oracle')
+      def compile(element, compiler, **kw):
+          if len(element.clauses) > 2:

+          return "nvl(%s)" % compiler.process(element.clauses)
+
+* :class:`~sqlalchemy.schema.DDLElement` - The root of all DDL expressions,
+  like CREATE TABLE, ALTER TABLE, etc. Compilation of ``DDLElement``
+  subclasses is issued by a ``DDLCompiler`` instead of a ``SQLCompiler``.
+  ``DDLElement`` also features ``Table`` and ``MetaData`` event hooks via the
+  ``execute_at()`` method, allowing the construct to be invoked during CREATE
+  TABLE and DROP TABLE sequences.
+
+* :class:`~sqlalchemy.sql.expression.Executable` - This is a mixin which
+  should be used with any expression class that represents a "standalone"
+  SQL statement that can be passed directly to an ``execute()`` method.  It
+  is already implicit within ``DDLElement`` and ``FunctionElement``.
+
+Further Examples
+================
+
+"UTC timestamp" function
+-------------------------
+
+A function that works like "CURRENT_TIMESTAMP" except applies the
+appropriate conversions so that the time is in UTC time.   Timestamps are best
+stored in relational databases as UTC, without time zones.   UTC so that your
+database doesn't think time has gone backwards in the hour when daylight
+savings ends, without timezones because timezones are like character
+encodings - they're best applied only at the endpoints of an application
+(i.e. convert to UTC upon user input, re-apply desired timezone upon display).
+
+For Postgresql and Microsoft SQL Server::
+
+    from sqlalchemy.sql import expression
+    from sqlalchemy.ext.compiler import compiles
+    from sqlalchemy.types import DateTime
+
+    class utcnow(expression.FunctionElement):
+        type = DateTime()
+
+    @compiles(utcnow, 'postgresql')
+    def pg_utcnow(element, compiler, **kw):
+        return "TIMEZONE('utc', CURRENT_TIMESTAMP)"
+
+    @compiles(utcnow, 'mssql')
+    def ms_utcnow(element, compiler, **kw):
+        return "GETUTCDATE()"
+
+Example usage::
+
+    from sqlalchemy import (
+                Table, Column, Integer, String, DateTime, MetaData
+            )
+    metadata = MetaData()
+    event = Table("event", metadata,
+        Column("id", Integer, primary_key=True),
+        Column("description", String(50), nullable=False),
+        Column("timestamp", DateTime, server_default=utcnow())
+    )
+
+"GREATEST" function
+-------------------
+
+The "GREATEST" function is given any number of arguments and returns the one
+that is of the highest value - its equivalent to Python's ``max``
+function.  A SQL standard version versus a CASE based version which only
+accommodates two arguments::
+
+    from sqlalchemy.sql import expression
+    from sqlalchemy.ext.compiler import compiles
+    from sqlalchemy.types import Numeric
+
+    class greatest(expression.FunctionElement):
+        type = Numeric()
+        name = 'greatest'
+
+    @compiles(greatest)
+    def default_greatest(element, compiler, **kw):
+        return compiler.visit_function(element)
+
+    @compiles(greatest, 'sqlite')
+    @compiles(greatest, 'mssql')
+    @compiles(greatest, 'oracle')
+    def case_greatest(element, compiler, **kw):
+        arg1, arg2 = list(element.clauses)
+        return "CASE WHEN %s > %s THEN %s ELSE %s END" % (
+            compiler.process(arg1),
+            compiler.process(arg2),
+            compiler.process(arg1),
+            compiler.process(arg2),
+        )
+
+Example usage::
+
+    Session.query(Account).\\
+            filter(
+                greatest(
+                    Account.checking_balance,
+                    Account.savings_balance) > 10000
+            )
+
+"false" expression
+------------------
+
+Render a "false" constant expression, rendering as "0" on platforms that
+don't have a "false" constant::
+
+    from sqlalchemy.sql import expression
+    from sqlalchemy.ext.compiler import compiles
+
+    class sql_false(expression.ColumnElement):
+        pass
+
+    @compiles(sql_false)
+    def default_false(element, compiler, **kw):
+        return "false"
+
+    @compiles(sql_false, 'mssql')
+    @compiles(sql_false, 'mysql')
+    @compiles(sql_false, 'oracle')
+    def int_false(element, compiler, **kw):
+        return "0"
+
+Example usage::
+
+    from sqlalchemy import select, union_all
+
+    exp = union_all(
+        select([users.c.name, sql_false().label("enrolled")]),
+        select([customers.c.name, customers.c.enrolled])

+Synopsis
+========
+
+SQLAlchemy object-relational configuration involves the
+combination of :class:`.Table`, :func:`.mapper`, and class
+objects to define a mapped class.
+:mod:`~sqlalchemy.ext.declarative` allows all three to be
+expressed at once within the class declaration. As much as
+possible, regular SQLAlchemy schema and ORM constructs are
+used directly, so that configuration between "classical" ORM
+usage and declarative remain highly similar.
+
+As a simple example::
+
+    from sqlalchemy.ext.declarative import declarative_base
+
+    Base = declarative_base()
+
+    class SomeClass(Base):
+        __tablename__ = 'some_table'
+        id = Column(Integer, primary_key=True)
+        name =  Column(String(50))
+
+Above, the :func:`declarative_base` callable returns a new base class from
+which all mapped classes should inherit. When the class definition is
+completed, a new :class:`.Table` and :func:`.mapper` will have been generated.
+
+The resulting table and mapper are accessible via
+``__table__`` and ``__mapper__`` attributes on the
+``SomeClass`` class::
+
+    # access the mapped Table
+    SomeClass.__table__
+
+    # access the Mapper
+    SomeClass.__mapper__
+
+Defining Attributes
+===================
+
+In the previous example, the :class:`.Column` objects are
+automatically named with the name of the attribute to which they are
+assigned.
+
+To name columns explicitly with a name distinct from their mapped attribute,
+just give the column a name.  Below, column "some_table_id" is mapped to the
+"id" attribute of `SomeClass`, but in SQL will be represented as
+"some_table_id"::
+
+    class SomeClass(Base):
+        __tablename__ = 'some_table'
+        id = Column("some_table_id", Integer, primary_key=True)
+
+Attributes may be added to the class after its construction, and they will be
+added to the underlying :class:`.Table` and
+:func:`.mapper` definitions as appropriate::
+
+    SomeClass.data = Column('data', Unicode)
+    SomeClass.related = relationship(RelatedInfo)
+
+Classes which are constructed using declarative can interact freely
+with classes that are mapped explicitly with :func:`.mapper`.
+
+It is recommended, though not required, that all tables
+share the same underlying :class:`~sqlalchemy.schema.MetaData` object,
+so that string-configured :class:`~sqlalchemy.schema.ForeignKey`
+references can be resolved without issue.
+
+Accessing the MetaData
+=======================
+
+The :func:`declarative_base` base class contains a
+:class:`.MetaData` object where newly defined
+:class:`.Table` objects are collected. This object is
+intended to be accessed directly for
+:class:`.MetaData`-specific operations. Such as, to issue
+CREATE statements for all tables::
+
+    engine = create_engine('sqlite://')
+    Base.metadata.create_all(engine)
+
+:func:`declarative_base` can also receive a pre-existing
+:class:`.MetaData` object, which allows a
+declarative setup to be associated with an already
+existing traditional collection of :class:`~sqlalchemy.schema.Table`
+objects::
+
+    mymetadata = MetaData()
+    Base = declarative_base(metadata=mymetadata)
+
+
+.. _declarative_configuring_relationships:
+
+Configuring Relationships
+=========================
+
+Relationships to other classes are done in the usual way, with the added
+feature that the class specified to :func:`~sqlalchemy.orm.relationship`
+may be a string name.  The "class registry" associated with ``Base``
+is used at mapper compilation time to resolve the name into the actual
+class object, which is expected to have been defined once the mapper
+configuration is used::
+
+    class User(Base):
+        __tablename__ = 'users'
+
+        id = Column(Integer, primary_key=True)
+        name = Column(String(50))
+        addresses = relationship("Address", backref="user")
+
+    class Address(Base):
+        __tablename__ = 'addresses'
+
+        id = Column(Integer, primary_key=True)
+        email = Column(String(50))
+        user_id = Column(Integer, ForeignKey('users.id'))
+
+Column constructs, since they are just that, are immediately usable,
+as below where we define a primary join condition on the ``Address``
+class using them::
+
+    class Address(Base):
+        __tablename__ = 'addresses'
+
+        id = Column(Integer, primary_key=True)
+        email = Column(String(50))
+        user_id = Column(Integer, ForeignKey('users.id'))
+        user = relationship(User, primaryjoin=user_id == User.id)
+
+In addition to the main argument for :func:`~sqlalchemy.orm.relationship`,
+other arguments which depend upon the columns present on an as-yet
+undefined class may also be specified as strings.  These strings are
+evaluated as Python expressions.  The full namespace available within
+this evaluation includes all classes mapped for this declarative base,
+as well as the contents of the ``sqlalchemy`` package, including
+expression functions like :func:`~sqlalchemy.sql.expression.desc` and
+:attr:`~sqlalchemy.sql.expression.func`::
+
+    class User(Base):
+        # ....
+        addresses = relationship("Address",
+                             order_by="desc(Address.email)",
+                             primaryjoin="Address.user_id==User.id")
+
+For the case where more than one module contains a class of the same name,
+string class names can also be specified as module-qualified paths
+within any of these string expressions::
+
+    class User(Base):
+        # ....
+        addresses = relationship("myapp.model.address.Address",
+                             order_by="desc(myapp.model.address.Address.email)",
+                             primaryjoin="myapp.model.address.Address.user_id=="
+                                            "myapp.model.user.User.id")
+
+The qualified path can be any partial path that removes ambiguity between
+the names.  For example, to disambiguate between
+``myapp.model.address.Address`` and ``myapp.model.lookup.Address``,
+we can specify ``address.Address`` or ``lookup.Address``::
+
+    class User(Base):
+        # ....
+        addresses = relationship("address.Address",
+                             order_by="desc(address.Address.email)",
+                             primaryjoin="address.Address.user_id=="
+                                            "User.id")
+
+.. versionadded:: 0.8
+   module-qualified paths can be used when specifying string arguments
+   with Declarative, in order to specify specific modules.
+
+Two alternatives also exist to using string-based attributes.  A lambda
+can also be used, which will be evaluated after all mappers have been
+configured::
+
+    class User(Base):
+        # ...
+        addresses = relationship(lambda: Address,
+                             order_by=lambda: desc(Address.email),
+                             primaryjoin=lambda: Address.user_id==User.id)
+
+Or, the relationship can be added to the class explicitly after the classes
+are available::
+
+    User.addresses = relationship(Address,
+                              primaryjoin=Address.user_id==User.id)
+
+
+
+.. _declarative_many_to_many:
+
+Configuring Many-to-Many Relationships
+======================================
+
+Many-to-many relationships are also declared in the same way
+with declarative as with traditional mappings. The
+``secondary`` argument to
+:func:`.relationship` is as usual passed a
+:class:`.Table` object, which is typically declared in the
+traditional way.  The :class:`.Table` usually shares
+the :class:`.MetaData` object used by the declarative base::
+
+    keywords = Table(
+        'keywords', Base.metadata,
+        Column('author_id', Integer, ForeignKey('authors.id')),
+        Column('keyword_id', Integer, ForeignKey('keywords.id'))
+        )
+
+    class Author(Base):
+        __tablename__ = 'authors'
+        id = Column(Integer, primary_key=True)
+        keywords = relationship("Keyword", secondary=keywords)
+
+Like other :func:`~sqlalchemy.orm.relationship` arguments, a string is accepted
+as well, passing the string name of the table as defined in the
+``Base.metadata.tables`` collection::
+
+    class Author(Base):
+        __tablename__ = 'authors'
+        id = Column(Integer, primary_key=True)
+        keywords = relationship("Keyword", secondary="keywords")
+
+As with traditional mapping, its generally not a good idea to use
+a :class:`.Table` as the "secondary" argument which is also mapped to
+a class, unless the :func:`.relationship` is declared with ``viewonly=True``.
+Otherwise, the unit-of-work system may attempt duplicate INSERT and
+DELETE statements against the underlying table.
+
+.. _declarative_sql_expressions:
+
+Defining SQL Expressions
+========================
+
+See :ref:`mapper_sql_expressions` for examples on declaratively
+mapping attributes to SQL expressions.
+
+.. _declarative_table_args:
+
+Table Configuration
+===================
+
+Table arguments other than the name, metadata, and mapped Column
+arguments are specified using the ``__table_args__`` class attribute.
+This attribute accommodates both positional as well as keyword
+arguments that are normally sent to the
+:class:`~sqlalchemy.schema.Table` constructor.
+The attribute can be specified in one of two forms. One is as a
+dictionary::
+
+    class MyClass(Base):
+        __tablename__ = 'sometable'
+        __table_args__ = {'mysql_engine':'InnoDB'}
+
+The other, a tuple, where each argument is positional
+(usually constraints)::
+
+    class MyClass(Base):
+        __tablename__ = 'sometable'
+        __table_args__ = (
+                ForeignKeyConstraint(['id'], ['remote_table.id']),
+                UniqueConstraint('foo'),
+                )
+
+Keyword arguments can be specified with the above form by
+specifying the last argument as a dictionary::
+
+    class MyClass(Base):
+        __tablename__ = 'sometable'
+        __table_args__ = (
+                ForeignKeyConstraint(['id'], ['remote_table.id']),
+                UniqueConstraint('foo'),
+                {'autoload':True}
+                )
+
+Using a Hybrid Approach with __table__
+=======================================
+
+As an alternative to ``__tablename__``, a direct
+:class:`~sqlalchemy.schema.Table` construct may be used.  The
+:class:`~sqlalchemy.schema.Column` objects, which in this case require
+their names, will be added to the mapping just like a regular mapping
+to a table::
+
+    class MyClass(Base):
+        __table__ = Table('my_table', Base.metadata,
+            Column('id', Integer, primary_key=True),
+            Column('name', String(50))
+        )
+
+``__table__`` provides a more focused point of control for establishing
+table metadata, while still getting most of the benefits of using declarative.
+An application that uses reflection might want to load table metadata elsewhere
+and pass it to declarative classes::
+
+    from sqlalchemy.ext.declarative import declarative_base
+
+    Base = declarative_base()
+    Base.metadata.reflect(some_engine)
+
+    class User(Base):
+        __table__ = metadata.tables['user']
+
+    class Address(Base):
+        __table__ = metadata.tables['address']
+
+Some configuration schemes may find it more appropriate to use ``__table__``,
+such as those which already take advantage of the data-driven nature of
+:class:`.Table` to customize and/or automate schema definition.
+
+Note that when the ``__table__`` approach is used, the object is immediately
+usable as a plain :class:`.Table` within the class declaration body itself,
+as a Python class is only another syntactical block.  Below this is illustrated
+by using the ``id`` column in the ``primaryjoin`` condition of a
+:func:`.relationship`::
+
+    class MyClass(Base):
+        __table__ = Table('my_table', Base.metadata,
+            Column('id', Integer, primary_key=True),
+            Column('name', String(50))
+        )
+
+        widgets = relationship(Widget,
+                    primaryjoin=Widget.myclass_id==__table__.c.id)
+
+Similarly, mapped attributes which refer to ``__table__`` can be placed inline,
+as below where we assign the ``name`` column to the attribute ``_name``,
+generating a synonym for ``name``::
+
+    from sqlalchemy.ext.declarative import synonym_for
+
+    class MyClass(Base):
+        __table__ = Table('my_table', Base.metadata,
+            Column('id', Integer, primary_key=True),
+            Column('name', String(50))
+        )
+
+        _name = __table__.c.name
+
+        @synonym_for("_name")
+        def name(self):
+            return "Name: %s" % _name
+
+Using Reflection with Declarative
+=================================
+
+It's easy to set up a :class:`.Table` that uses ``autoload=True``
+in conjunction with a mapped class::
+
+    class MyClass(Base):
+        __table__ = Table('mytable', Base.metadata,
+                        autoload=True, autoload_with=some_engine)
+
+However, one improvement that can be made here is to not
+require the :class:`.Engine` to be available when classes are
+being first declared.   To achieve this, use the
+:class:`.DeferredReflection` mixin, which sets up mappings
+only after a special ``prepare(engine)`` step is called::
+
+    from sqlalchemy.ext.declarative import declarative_base, DeferredReflection
+
+    Base = declarative_base(cls=DeferredReflection)
+
+    class Foo(Base):
+        __tablename__ = 'foo'
+        bars = relationship("Bar")
+
+    class Bar(Base):
+        __tablename__ = 'bar'
+
+        # illustrate overriding of "bar.foo_id" to have
+        # a foreign key constraint otherwise not
+        # reflected, such as when using MySQL
+        foo_id = Column(Integer, ForeignKey('foo.id'))
+
+    Base.prepare(e)
+
+.. versionadded:: 0.8
+   Added :class:`.DeferredReflection`.
+
+Mapper Configuration
+====================
+
+Declarative makes use of the :func:`~.orm.mapper` function internally
+when it creates the mapping to the declared table.   The options
+for :func:`~.orm.mapper` are passed directly through via the
+``__mapper_args__`` class attribute.  As always, arguments which reference
+locally mapped columns can reference them directly from within the
+class declaration::
+
+    from datetime import datetime
+
+    class Widget(Base):
+        __tablename__ = 'widgets'
+
+        id = Column(Integer, primary_key=True)
+        timestamp = Column(DateTime, nullable=False)
+
+        __mapper_args__ = {
+                        'version_id_col': timestamp,
+                        'version_id_generator': lambda v:datetime.now()
+                    }
+
+.. _declarative_inheritance:
+
+Inheritance Configuration
+=========================
+
+Declarative supports all three forms of inheritance as intuitively
+as possible.  The ``inherits`` mapper keyword argument is not needed
+as declarative will determine this from the class itself.   The various
+"polymorphic" keyword arguments are specified using ``__mapper_args__``.
+
+Joined Table Inheritance
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Joined table inheritance is defined as a subclass that defines its own
+table::
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        __tablename__ = 'engineers'
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+        id = Column(Integer, ForeignKey('people.id'), primary_key=True)
+        primary_language = Column(String(50))
+
+Note that above, the ``Engineer.id`` attribute, since it shares the
+same attribute name as the ``Person.id`` attribute, will in fact
+represent the ``people.id`` and ``engineers.id`` columns together,
+with the "Engineer.id" column taking precedence if queried directly.
+To provide the ``Engineer`` class with an attribute that represents
+only the ``engineers.id`` column, give it a different attribute name::
+
+    class Engineer(Person):
+        __tablename__ = 'engineers'
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+        engineer_id = Column('id', Integer, ForeignKey('people.id'),
+                                                    primary_key=True)
+        primary_language = Column(String(50))
+
+
+.. versionchanged:: 0.7 joined table inheritance favors the subclass
+   column over that of the superclass, such as querying above
+   for ``Engineer.id``.  Prior to 0.7 this was the reverse.
+
+.. _declarative_single_table:
+
+Single Table Inheritance
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Single table inheritance is defined as a subclass that does not have
+its own table; you just leave out the ``__table__`` and ``__tablename__``
+attributes::
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+        primary_language = Column(String(50))
+
+When the above mappers are configured, the ``Person`` class is mapped
+to the ``people`` table *before* the ``primary_language`` column is
+defined, and this column will not be included in its own mapping.
+When ``Engineer`` then defines the ``primary_language`` column, the
+column is added to the ``people`` table so that it is included in the
+mapping for ``Engineer`` and is also part of the table's full set of
+columns.  Columns which are not mapped to ``Person`` are also excluded
+from any other single or joined inheriting classes using the
+``exclude_properties`` mapper argument.  Below, ``Manager`` will have
+all the attributes of ``Person`` and ``Manager`` but *not* the
+``primary_language`` attribute of ``Engineer``::
+
+    class Manager(Person):
+        __mapper_args__ = {'polymorphic_identity': 'manager'}
+        golf_swing = Column(String(50))
+
+The attribute exclusion logic is provided by the
+``exclude_properties`` mapper argument, and declarative's default
+behavior can be disabled by passing an explicit ``exclude_properties``
+collection (empty or otherwise) to the ``__mapper_args__``.
+
+Resolving Column Conflicts
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Note above that the ``primary_language`` and ``golf_swing`` columns
+are "moved up" to be applied to ``Person.__table__``, as a result of their
+declaration on a subclass that has no table of its own.   A tricky case
+comes up when two subclasses want to specify *the same* column, as below::
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+        start_date = Column(DateTime)
+
+    class Manager(Person):
+        __mapper_args__ = {'polymorphic_identity': 'manager'}
+        start_date = Column(DateTime)
+
+Above, the ``start_date`` column declared on both ``Engineer`` and ``Manager``
+will result in an error::
+
+    sqlalchemy.exc.ArgumentError: Column 'start_date' on class
+    <class '__main__.Manager'> conflicts with existing
+    column 'people.start_date'
+
+In a situation like this, Declarative can't be sure
+of the intent, especially if the ``start_date`` columns had, for example,
+different types.   A situation like this can be resolved by using
+:class:`.declared_attr` to define the :class:`.Column` conditionally, taking
+care to return the **existing column** via the parent ``__table__`` if it
+already exists::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+
+        @declared_attr
+        def start_date(cls):
+            "Start date column, if not present already."
+            return Person.__table__.c.get('start_date', Column(DateTime))
+
+    class Manager(Person):
+        __mapper_args__ = {'polymorphic_identity': 'manager'}
+
+        @declared_attr
+        def start_date(cls):
+            "Start date column, if not present already."
+            return Person.__table__.c.get('start_date', Column(DateTime))
+
+Above, when ``Manager`` is mapped, the ``start_date`` column is
+already present on the ``Person`` class.  Declarative lets us return
+that :class:`.Column` as a result in this case, where it knows to skip
+re-assigning the same column. If the mapping is mis-configured such
+that the ``start_date`` column is accidentally re-assigned to a
+different table (such as, if we changed ``Manager`` to be joined
+inheritance without fixing ``start_date``), an error is raised which
+indicates an existing :class:`.Column` is trying to be re-assigned to
+a different owning :class:`.Table`.
+
+.. versionadded:: 0.8 :class:`.declared_attr` can be used on a non-mixin
+   class, and the returned :class:`.Column` or other mapped attribute
+   will be applied to the mapping as any other attribute.  Previously,
+   the resulting attribute would be ignored, and also result in a warning
+   being emitted when a subclass was created.
+
+.. versionadded:: 0.8 :class:`.declared_attr`, when used either with a
+   mixin or non-mixin declarative class, can return an existing
+   :class:`.Column` already assigned to the parent :class:`.Table`,
+   to indicate that the re-assignment of the :class:`.Column` should be
+   skipped, however should still be mapped on the target class,
+   in order to resolve duplicate column conflicts.
+
+The same concept can be used with mixin classes (see
+:ref:`declarative_mixins`)::
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class HasStartDate(object):
+        @declared_attr
+        def start_date(cls):
+            return cls.__table__.c.get('start_date', Column(DateTime))
+
+    class Engineer(HasStartDate, Person):
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+
+    class Manager(HasStartDate, Person):
+        __mapper_args__ = {'polymorphic_identity': 'manager'}
+
+The above mixin checks the local ``__table__`` attribute for the column.
+Because we're using single table inheritance, we're sure that in this case,
+``cls.__table__`` refers to ``People.__table__``.  If we were mixing joined-
+and single-table inheritance, we might want our mixin to check more carefully
+if ``cls.__table__`` is really the :class:`.Table` we're looking for.
+
+Concrete Table Inheritance
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Concrete is defined as a subclass which has its own table and sets the
+``concrete`` keyword argument to ``True``::
+
+    class Person(Base):
+        __tablename__ = 'people'
+        id = Column(Integer, primary_key=True)
+        name = Column(String(50))
+
+    class Engineer(Person):
+        __tablename__ = 'engineers'
+        __mapper_args__ = {'concrete':True}
+        id = Column(Integer, primary_key=True)
+        primary_language = Column(String(50))
+        name = Column(String(50))
+
+Usage of an abstract base class is a little less straightforward as it
+requires usage of :func:`~sqlalchemy.orm.util.polymorphic_union`,
+which needs to be created with the :class:`.Table` objects
+before the class is built::
+
+    engineers = Table('engineers', Base.metadata,
+                    Column('id', Integer, primary_key=True),
+                    Column('name', String(50)),
+                    Column('primary_language', String(50))
+                )
+    managers = Table('managers', Base.metadata,
+                    Column('id', Integer, primary_key=True),
+                    Column('name', String(50)),
+                    Column('golf_swing', String(50))
+                )
+
+    punion = polymorphic_union({
+        'engineer':engineers,
+        'manager':managers
+    }, 'type', 'punion')
+
+    class Person(Base):
+        __table__ = punion
+        __mapper_args__ = {'polymorphic_on':punion.c.type}
+
+    class Engineer(Person):
+        __table__ = engineers
+        __mapper_args__ = {'polymorphic_identity':'engineer', 'concrete':True}
+
+    class Manager(Person):
+        __table__ = managers
+        __mapper_args__ = {'polymorphic_identity':'manager', 'concrete':True}
+
+.. _declarative_concrete_helpers:
+
+Using the Concrete Helpers
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Helper classes provides a simpler pattern for concrete inheritance.
+With these objects, the ``__declare_first__`` helper is used to configure the
+"polymorphic" loader for the mapper after all subclasses have been declared.
+
+.. versionadded:: 0.7.3
+
+An abstract base can be declared using the
+:class:`.AbstractConcreteBase` class::
+
+    from sqlalchemy.ext.declarative import AbstractConcreteBase
+
+    class Employee(AbstractConcreteBase, Base):
+        pass
+
+To have a concrete ``employee`` table, use :class:`.ConcreteBase` instead::
+
+    from sqlalchemy.ext.declarative import ConcreteBase
+
+    class Employee(ConcreteBase, Base):
+        __tablename__ = 'employee'
+        employee_id = Column(Integer, primary_key=True)
+        name = Column(String(50))
+        __mapper_args__ = {
+                        'polymorphic_identity':'employee',
+                        'concrete':True}
+
+
+Either ``Employee`` base can be used in the normal fashion::
+
+    class Manager(Employee):
+        __tablename__ = 'manager'
+        employee_id = Column(Integer, primary_key=True)
+        name = Column(String(50))
+        manager_data = Column(String(40))
+        __mapper_args__ = {
+                        'polymorphic_identity':'manager',
+                        'concrete':True}
+
+    class Engineer(Employee):
+        __tablename__ = 'engineer'
+        employee_id = Column(Integer, primary_key=True)
+        name = Column(String(50))
+        engineer_info = Column(String(40))
+        __mapper_args__ = {'polymorphic_identity':'engineer',
+                        'concrete':True}
+
+
+The :class:`.AbstractConcreteBase` class is itself mapped, and can be
+used as a target of relationships::
+
+    class Company(Base):
+        __tablename__ = 'company'
+
+        id = Column(Integer, primary_key=True)
+        employees = relationship("Employee",
+                        primaryjoin="Company.id == Employee.company_id")
+
+
+.. versionchanged:: 0.9.3 Support for use of :class:`.AbstractConcreteBase`
+   as the target of a :func:`.relationship` has been improved.
+
+It can also be queried directly::
+
+    for employee in session.query(Employee).filter(Employee.name == 'qbert'):
+        print(employee)
+
+
+.. _declarative_mixins:
+
+Mixin and Custom Base Classes
+==============================
+
+A common need when using :mod:`~sqlalchemy.ext.declarative` is to
+share some functionality, such as a set of common columns, some common
+table options, or other mapped properties, across many
+classes.  The standard Python idioms for this is to have the classes
+inherit from a base which includes these common features.
+
+When using :mod:`~sqlalchemy.ext.declarative`, this idiom is allowed
+via the usage of a custom declarative base class, as well as a "mixin" class
+which is inherited from in addition to the primary base.  Declarative
+includes several helper features to make this work in terms of how
+mappings are declared.   An example of some commonly mixed-in
+idioms is below::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class MyMixin(object):
+
+        @declared_attr
+        def __tablename__(cls):
+            return cls.__name__.lower()
+
+        __table_args__ = {'mysql_engine': 'InnoDB'}
+        __mapper_args__= {'always_refresh': True}
+
+        id =  Column(Integer, primary_key=True)
+
+    class MyModel(MyMixin, Base):
+        name = Column(String(1000))
+
+Where above, the class ``MyModel`` will contain an "id" column
+as the primary key, a ``__tablename__`` attribute that derives
+from the name of the class itself, as well as ``__table_args__``
+and ``__mapper_args__`` defined by the ``MyMixin`` mixin class.
+
+There's no fixed convention over whether ``MyMixin`` precedes
+``Base`` or not.  Normal Python method resolution rules apply, and
+the above example would work just as well with::
+
+    class MyModel(Base, MyMixin):
+        name = Column(String(1000))
+
+This works because ``Base`` here doesn't define any of the
+variables that ``MyMixin`` defines, i.e. ``__tablename__``,
+``__table_args__``, ``id``, etc.   If the ``Base`` did define
+an attribute of the same name, the class placed first in the
+inherits list would determine which attribute is used on the
+newly defined class.
+
+Augmenting the Base
+~~~~~~~~~~~~~~~~~~~
+
+In addition to using a pure mixin, most of the techniques in this
+section can also be applied to the base class itself, for patterns that
+should apply to all classes derived from a particular base.  This is achieved
+using the ``cls`` argument of the :func:`.declarative_base` function::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class Base(object):
+        @declared_attr
+        def __tablename__(cls):
+            return cls.__name__.lower()
+
+        __table_args__ = {'mysql_engine': 'InnoDB'}
+
+        id =  Column(Integer, primary_key=True)
+
+    from sqlalchemy.ext.declarative import declarative_base
+
+    Base = declarative_base(cls=Base)
+
+    class MyModel(Base):
+        name = Column(String(1000))
+
+Where above, ``MyModel`` and all other classes that derive from ``Base`` will
+have a table name derived from the class name, an ``id`` primary key column,
+as well as the "InnoDB" engine for MySQL.
+
+Mixing in Columns
+~~~~~~~~~~~~~~~~~
+
+The most basic way to specify a column on a mixin is by simple
+declaration::
+
+    class TimestampMixin(object):
+        created_at = Column(DateTime, default=func.now())
+
+    class MyModel(TimestampMixin, Base):
+        __tablename__ = 'test'
+
+        id =  Column(Integer, primary_key=True)
+        name = Column(String(1000))
+
+Where above, all declarative classes that include ``TimestampMixin``
+will also have a column ``created_at`` that applies a timestamp to
+all row insertions.
+
+Those familiar with the SQLAlchemy expression language know that
+the object identity of clause elements defines their role in a schema.
+Two ``Table`` objects ``a`` and ``b`` may both have a column called
+``id``, but the way these are differentiated is that ``a.c.id``
+and ``b.c.id`` are two distinct Python objects, referencing their
+parent tables ``a`` and ``b`` respectively.
+
+In the case of the mixin column, it seems that only one
+:class:`.Column` object is explicitly created, yet the ultimate
+``created_at`` column above must exist as a distinct Python object
+for each separate destination class.  To accomplish this, the declarative
+extension creates a **copy** of each :class:`.Column` object encountered on
+a class that is detected as a mixin.
+
+This copy mechanism is limited to simple columns that have no foreign
+keys, as a :class:`.ForeignKey` itself contains references to columns
+which can't be properly recreated at this level.  For columns that
+have foreign keys, as well as for the variety of mapper-level constructs
+that require destination-explicit context, the
+:class:`~.declared_attr` decorator is provided so that
+patterns common to many classes can be defined as callables::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class ReferenceAddressMixin(object):
+        @declared_attr
+        def address_id(cls):
+            return Column(Integer, ForeignKey('address.id'))
+
+    class User(ReferenceAddressMixin, Base):
+        __tablename__ = 'user'
+        id = Column(Integer, primary_key=True)
+
+Where above, the ``address_id`` class-level callable is executed at the
+point at which the ``User`` class is constructed, and the declarative
+extension can use the resulting :class:`.Column` object as returned by
+the method without the need to copy it.
+
+.. versionchanged:: > 0.6.5
+    Rename 0.6.5 ``sqlalchemy.util.classproperty``
+    into :class:`~.declared_attr`.
+
+Columns generated by :class:`~.declared_attr` can also be
+referenced by ``__mapper_args__`` to a limited degree, currently
+by ``polymorphic_on`` and ``version_id_col``, by specifying the
+classdecorator itself into the dictionary - the declarative extension
+will resolve them at class construction time::
+
+    class MyMixin:
+        @declared_attr
+        def type_(cls):
+            return Column(String(50))
+
+        __mapper_args__= {'polymorphic_on':type_}
+
+    class MyModel(MyMixin, Base):
+        __tablename__='test'
+        id =  Column(Integer, primary_key=True)
+
+
+
+Mixing in Relationships
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Relationships created by :func:`~sqlalchemy.orm.relationship` are provided
+with declarative mixin classes exclusively using the
+:class:`.declared_attr` approach, eliminating any ambiguity
+which could arise when copying a relationship and its possibly column-bound
+contents. Below is an example which combines a foreign key column and a
+relationship so that two classes ``Foo`` and ``Bar`` can both be configured to
+reference a common target class via many-to-one::
+
+    class RefTargetMixin(object):
+        @declared_attr
+        def target_id(cls):
+            return Column('target_id', ForeignKey('target.id'))
+
+        @declared_attr
+        def target(cls):
+            return relationship("Target")
+
+    class Foo(RefTargetMixin, Base):
+        __tablename__ = 'foo'
+        id = Column(Integer, primary_key=True)
+
+    class Bar(RefTargetMixin, Base):
+        __tablename__ = 'bar'
+        id = Column(Integer, primary_key=True)
+
+    class Target(Base):
+        __tablename__ = 'target'
+        id = Column(Integer, primary_key=True)
+
+Using Advanced Relationship Arguments (e.g. ``primaryjoin``, etc.)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+:func:`~sqlalchemy.orm.relationship` definitions which require explicit
+primaryjoin, order_by etc. expressions should in all but the most
+simplistic cases use **late bound** forms
+for these arguments, meaning, using either the string form or a lambda.
+The reason for this is that the related :class:`.Column` objects which are to
+be configured using ``@declared_attr`` are not available to another
+``@declared_attr`` attribute; while the methods will work and return new
+:class:`.Column` objects, those are not the :class:`.Column` objects that
+Declarative will be using as it calls the methods on its own, thus using
+*different* :class:`.Column` objects.
+
+The canonical example is the primaryjoin condition that depends upon
+another mixed-in column::
+
+    class RefTargetMixin(object):
+        @declared_attr
+        def target_id(cls):
+            return Column('target_id', ForeignKey('target.id'))
+
+        @declared_attr
+        def target(cls):
+            return relationship(Target,
+                primaryjoin=Target.id==cls.target_id   # this is *incorrect*
+            )
+
+Mapping a class using the above mixin, we will get an error like::
+
+    sqlalchemy.exc.InvalidRequestError: this ForeignKey's parent column is not
+    yet associated with a Table.
+
+This is because the ``target_id`` :class:`.Column` we've called upon in our
+``target()`` method is not the same :class:`.Column` that declarative is
+actually going to map to our table.
+
+The condition above is resolved using a lambda::
+
+    class RefTargetMixin(object):
+        @declared_attr
+        def target_id(cls):
+            return Column('target_id', ForeignKey('target.id'))
+
+        @declared_attr
+        def target(cls):
+            return relationship(Target,
+                primaryjoin=lambda: Target.id==cls.target_id
+            )
+
+or alternatively, the string form (which ultimately generates a lambda)::
+
+    class RefTargetMixin(object):

+        def target_id(cls):
+            return Column('target_id', ForeignKey('target.id'))
+

+            return relationship("Target",

+            )
+
+Mixing in deferred(), column_property(), and other MapperProperty classes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Like :func:`~sqlalchemy.orm.relationship`, all
+:class:`~sqlalchemy.orm.interfaces.MapperProperty` subclasses such as
+:func:`~sqlalchemy.orm.deferred`, :func:`~sqlalchemy.orm.column_property`,
+etc. ultimately involve references to columns, and therefore, when
+used with declarative mixins, have the :class:`.declared_attr`
+requirement so that no reliance on copying is needed::
+
+    class SomethingMixin(object):
+
+        @declared_attr
+        def dprop(cls):
+            return deferred(Column(Integer))
+
+    class Something(SomethingMixin, Base):
+        __tablename__ = "something"
+
+Mixing in Association Proxy and Other Attributes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Mixins can specify user-defined attributes as well as other extension
+units such as :func:`.association_proxy`.   The usage of
+:class:`.declared_attr` is required in those cases where the attribute must
+be tailored specifically to the target subclass.   An example is when
+constructing multiple :func:`.association_proxy` attributes which each
+target a different type of child object.  Below is an
+:func:`.association_proxy` / mixin example which provides a scalar list of
+string values to an implementing class::
+
+    from sqlalchemy import Column, Integer, ForeignKey, String
+    from sqlalchemy.orm import relationship
+    from sqlalchemy.ext.associationproxy import association_proxy
+    from sqlalchemy.ext.declarative import declarative_base, declared_attr
+
+    Base = declarative_base()
+
+    class HasStringCollection(object):
+        @declared_attr
+        def _strings(cls):
+            class StringAttribute(Base):
+                __tablename__ = cls.string_table_name
+                id = Column(Integer, primary_key=True)
+                value = Column(String(50), nullable=False)
+                parent_id = Column(Integer,
+                                ForeignKey('%s.id' % cls.__tablename__),
+                                nullable=False)
+                def __init__(self, value):
+                    self.value = value
+
+            return relationship(StringAttribute)
+
+        @declared_attr
+        def strings(cls):
+            return association_proxy('_strings', 'value')
+
+    class TypeA(HasStringCollection, Base):
+        __tablename__ = 'type_a'
+        string_table_name = 'type_a_strings'
+        id = Column(Integer(), primary_key=True)
+
+    class TypeB(HasStringCollection, Base):
+        __tablename__ = 'type_b'
+        string_table_name = 'type_b_strings'
+        id = Column(Integer(), primary_key=True)
+
+Above, the ``HasStringCollection`` mixin produces a :func:`.relationship`
+which refers to a newly generated class called ``StringAttribute``.  The
+``StringAttribute`` class is generated with its own :class:`.Table`
+definition which is local to the parent class making usage of the
+``HasStringCollection`` mixin.  It also produces an :func:`.association_proxy`
+object which proxies references to the ``strings`` attribute onto the ``value``
+attribute of each ``StringAttribute`` instance.
+
+``TypeA`` or ``TypeB`` can be instantiated given the constructor
+argument ``strings``, a list of strings::
+
+    ta = TypeA(strings=['foo', 'bar'])
+    tb = TypeA(strings=['bat', 'bar'])
+
+This list will generate a collection
+of ``StringAttribute`` objects, which are persisted into a table that's
+local to either the ``type_a_strings`` or ``type_b_strings`` table::
+
+    >>> print ta._strings
+    [<__main__.StringAttribute object at 0x10151cd90>,
+        <__main__.StringAttribute object at 0x10151ce10>]
+
+When constructing the :func:`.association_proxy`, the
+:class:`.declared_attr` decorator must be used so that a distinct
+:func:`.association_proxy` object is created for each of the ``TypeA``
+and ``TypeB`` classes.
+
+.. versionadded:: 0.8 :class:`.declared_attr` is usable with non-mapped
+   attributes, including user-defined attributes as well as
+   :func:`.association_proxy`.
+
+
+Controlling table inheritance with mixins
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``__tablename__`` attribute in conjunction with the hierarchy of
+classes involved in a declarative mixin scenario controls what type of
+table inheritance, if any,
+is configured by the declarative extension.
+
+If the ``__tablename__`` is computed by a mixin, you may need to
+control which classes get the computed attribute in order to get the
+type of table inheritance you require.
+
+For example, if you had a mixin that computes ``__tablename__`` but
+where you wanted to use that mixin in a single table inheritance
+hierarchy, you can explicitly specify ``__tablename__`` as ``None`` to
+indicate that the class should not have a table mapped::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class Tablename:
+        @declared_attr
+        def __tablename__(cls):
+            return cls.__name__.lower()
+
+    class Person(Tablename, Base):
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        __tablename__ = None
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+        primary_language = Column(String(50))
+
+Alternatively, you can make the mixin intelligent enough to only
+return a ``__tablename__`` in the event that no table is already
+mapped in the inheritance hierarchy. To help with this, a
+:func:`~sqlalchemy.ext.declarative.has_inherited_table` helper
+function is provided that returns ``True`` if a parent class already
+has a mapped table.
+
+As an example, here's a mixin that will only allow single table
+inheritance::
+
+    from sqlalchemy.ext.declarative import declared_attr
+    from sqlalchemy.ext.declarative import has_inherited_table
+
+    class Tablename(object):
+        @declared_attr
+        def __tablename__(cls):
+            if has_inherited_table(cls):
+                return None
+            return cls.__name__.lower()
+
+    class Person(Tablename, Base):
+        id = Column(Integer, primary_key=True)
+        discriminator = Column('type', String(50))
+        __mapper_args__ = {'polymorphic_on': discriminator}
+
+    class Engineer(Person):
+        primary_language = Column(String(50))
+        __mapper_args__ = {'polymorphic_identity': 'engineer'}
+
+
+Combining Table/Mapper Arguments from Multiple Mixins
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In the case of ``__table_args__`` or ``__mapper_args__``
+specified with declarative mixins, you may want to combine
+some parameters from several mixins with those you wish to
+define on the class iteself. The
+:class:`.declared_attr` decorator can be used
+here to create user-defined collation routines that pull
+from multiple collections::
+
+    from sqlalchemy.ext.declarative import declared_attr
+
+    class MySQLSettings(object):
+        __table_args__ = {'mysql_engine':'InnoDB'}
+
+    class MyOtherMixin(object):
+        __table_args__ = {'info':'foo'}
+
+    class MyModel(MySQLSettings, MyOtherMixin, Base):
+        __tablename__='my_model'
+
+        @declared_attr
+        def __table_args__(cls):
+            args = dict()
+            args.update(MySQLSettings.__table_args__)
+            args.update(MyOtherMixin.__table_args__)
+            return args
+
+        id =  Column(Integer, primary_key=True)
+
+Creating Indexes with Mixins
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To define a named, potentially multicolumn :class:`.Index` that applies to all
+tables derived from a mixin, use the "inline" form of :class:`.Index` and
+establish it as part of ``__table_args__``::
+
+    class MyMixin(object):
+        a =  Column(Integer)
+        b =  Column(Integer)
+
+        @declared_attr
+        def __table_args__(cls):
+            return (Index('test_idx_%s' % cls.__tablename__, 'a', 'b'),)
+
+    class MyModel(MyMixin, Base):
+        __tablename__ = 'atable'
+        c =  Column(Integer,primary_key=True)
+
+Special Directives
+==================
+
+``__declare_last__()``
+~~~~~~~~~~~~~~~~~~~~~~
+
+The ``__declare_last__()`` hook allows definition of
+a class level function that is automatically called by the
+:meth:`.MapperEvents.after_configured` event, which occurs after mappings are
+assumed to be completed and the 'configure' step has finished::
+
+    class MyClass(Base):
+        @classmethod
+        def __declare_last__(cls):
+            ""
+            # do something with mappings
+
+.. versionadded:: 0.7.3
+
+``__declare_first__()``
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Like ``__declare_last__()``, but is called at the beginning of mapper
+configuration via the :meth:`.MapperEvents.before_configured` event::
+
+    class MyClass(Base):
+        @classmethod
+        def __declare_first__(cls):
+            ""
+            # do something before mappings are configured
+
+.. versionadded:: 0.9.3
+
+.. _declarative_abstract:
+
+``__abstract__``
+~~~~~~~~~~~~~~~~~~~
+
+``__abstract__`` causes declarative to skip the production
+of a table or mapper for the class entirely.  A class can be added within a
+hierarchy in the same way as mixin (see :ref:`declarative_mixins`), allowing
+subclasses to extend just from the special class::
+
+    class SomeAbstractBase(Base):
+        __abstract__ = True
+
+        def some_helpful_method(self):
+            ""
+
+        @declared_attr
+        def __mapper_args__(cls):
+            return {"helpful mapper arguments":True}
+
+    class MyMappedClass(SomeAbstractBase):
+        ""
+
+One possible use of ``__abstract__`` is to use a distinct
+:class:`.MetaData` for different bases::
+
+    Base = declarative_base()
+
+    class DefaultBase(Base):
+        __abstract__ = True
+        metadata = MetaData()
+
+    class OtherBase(Base):
+        __abstract__ = True
+        metadata = MetaData()
+
+Above, classes which inherit from ``DefaultBase`` will use one
+:class:`.MetaData` as the registry of tables, and those which inherit from
+``OtherBase`` will use a different one. The tables themselves can then be
+created perhaps within distinct databases::
+
+    DefaultBase.metadata.create_all(some_engine)
+    OtherBase.metadata_create_all(some_other_engine)
+
+.. versionadded:: 0.7.3
+
+Class Constructor
+=================
+
+As a convenience feature, the :func:`declarative_base` sets a default
+constructor on classes which takes keyword arguments, and assigns them
+to the named attributes::
+
+    e = Engineer(primary_language='python')
+
+Sessions
+========
+
+Note that ``declarative`` does nothing special with sessions, and is
+only intended as an easier way to configure mappers and
+:class:`~sqlalchemy.schema.Table` objects.  A typical application
+setup using :class:`~sqlalchemy.orm.scoping.scoped_session` might look like::
+
+    engine = create_engine('postgresql://scott:tiger@localhost/test')
+    Session = scoped_session(sessionmaker(autocommit=False,
+                                          autoflush=False,
+                                          bind=engine))
+    Base = declarative_base()
+
+Mapped instances then make usage of
+:class:`~sqlalchemy.orm.session.Session` in the usual way.

+    """A helper class for construction of mappings based on
+    a deferred reflection step.
+
+    Normally, declarative can be used with reflection by
+    setting a :class:`.Table` object using autoload=True
+    as the ``__table__`` attribute on a declarative class.
+    The caveat is that the :class:`.Table` must be fully
+    reflected, or at the very least have a primary key column,
+    at the point at which a normal declarative mapping is
+    constructed, meaning the :class:`.Engine` must be available
+    at class declaration time.
+
+    The :class:`.DeferredReflection` mixin moves the construction
+    of mappers to be at a later point, after a specific
+    method is called which first reflects all :class:`.Table`
+    objects created so far.   Classes can define it as such::
+
+        from sqlalchemy.ext.declarative import declarative_base
+        from sqlalchemy.ext.declarative import DeferredReflection
+        Base = declarative_base()
+
+        class MyClass(DeferredReflection, Base):
+            __tablename__ = 'mytable'
+
+    Above, ``MyClass`` is not yet mapped.   After a series of
+    classes have been defined in the above fashion, all tables
+    can be reflected and mappings created using
+    :meth:`.prepare`::
+
+        engine = create_engine("someengine://...")
+        DeferredReflection.prepare(engine)
+
+    The :class:`.DeferredReflection` mixin can be applied to individual
+    classes, used as the base for the declarative base itself,
+    or used in a custom abstract class.   Using an abstract base
+    allows that only a subset of classes to be prepared for a
+    particular prepare step, which is necessary for applications
+    that use more than one engine.  For example, if an application
+    has two engines, you might use two bases, and prepare each
+    separately, e.g.::
+
+        class ReflectedOne(DeferredReflection, Base):
+            __abstract__ = True
+
+        class ReflectedTwo(DeferredReflection, Base):

+
+        class MyClass(ReflectedOne):
+            __tablename__ = 'mytable'
+
+        class MyOtherClass(ReflectedOne):
+            __tablename__ = 'myothertable'
+
+        class YetAnotherClass(ReflectedTwo):
+            __tablename__ = 'yetanothertable'
+
+        # ... etc.
+
+    Above, the class hierarchies for ``ReflectedOne`` and
+    ``ReflectedTwo`` can be configured separately::
+
+        ReflectedOne.prepare(engine_one)
+        ReflectedTwo.prepare(engine_two)

+"""Define attributes on ORM-mapped classes that have "hybrid" behavior.
+
+"hybrid" means the attribute has distinct behaviors defined at the
+class level and at the instance level.
+
+The :mod:`~sqlalchemy.ext.hybrid` extension provides a special form of
+method decorator, is around 50 lines of code and has almost no
+dependencies on the rest of SQLAlchemy.  It can, in theory, work with
+any descriptor-based expression system.
+
+Consider a mapping ``Interval``, representing integer ``start`` and ``end``
+values. We can define higher level functions on mapped classes that produce
+SQL expressions at the class level, and Python expression evaluation at the
+instance level.  Below, each function decorated with :class:`.hybrid_method` or
+:class:`.hybrid_property` may receive ``self`` as an instance of the class, or
+as the class itself::
+
+    from sqlalchemy import Column, Integer
+    from sqlalchemy.ext.declarative import declarative_base
+    from sqlalchemy.orm import Session, aliased
+    from sqlalchemy.ext.hybrid import hybrid_property, hybrid_method
+
+    Base = declarative_base()
+
+    class Interval(Base):
+        __tablename__ = 'interval'
+
+        id = Column(Integer, primary_key=True)
+        start = Column(Integer, nullable=False)
+        end = Column(Integer, nullable=False)
+
+        def __init__(self, start, end):
+            self.start = start
+            self.end = end
+
+        @hybrid_property
+        def length(self):
+            return self.end - self.start
+
+        @hybrid_method
+        def contains(self,point):
+            return (self.start <= point) & (point < self.end)
+
+        @hybrid_method
+        def intersects(self, other):
+            return self.contains(other.start) | self.contains(other.end)
+
+Above, the ``length`` property returns the difference between the
+``end`` and ``start`` attributes.  With an instance of ``Interval``,
+this subtraction occurs in Python, using normal Python descriptor
+mechanics::
+
+    >>> i1 = Interval(5, 10)
+    >>> i1.length
+    5
+
+When dealing with the ``Interval`` class itself, the :class:`.hybrid_property`
+descriptor evaluates the function body given the ``Interval`` class as
+the argument, which when evaluated with SQLAlchemy expression mechanics
+returns a new SQL expression::
+
+    >>> print Interval.length
+    interval."end" - interval.start
+
+    >>> print Session().query(Interval).filter(Interval.length > 10)
+    SELECT interval.id AS interval_id, interval.start AS interval_start,
+    interval."end" AS interval_end
+    FROM interval
+    WHERE interval."end" - interval.start > :param_1
+
+ORM methods such as :meth:`~.Query.filter_by` generally use ``getattr()`` to
+locate attributes, so can also be used with hybrid attributes::
+
+    >>> print Session().query(Interval).filter_by(length=5)
+    SELECT interval.id AS interval_id, interval.start AS interval_start,
+    interval."end" AS interval_end
+    FROM interval
+    WHERE interval."end" - interval.start = :param_1
+
+The ``Interval`` class example also illustrates two methods,
+``contains()`` and ``intersects()``, decorated with
+:class:`.hybrid_method`. This decorator applies the same idea to
+methods that :class:`.hybrid_property` applies to attributes.   The
+methods return boolean values, and take advantage of the Python ``|``
+and ``&`` bitwise operators to produce equivalent instance-level and
+SQL expression-level boolean behavior::
+
+    >>> i1.contains(6)
+    True
+    >>> i1.contains(15)
+    False
+    >>> i1.intersects(Interval(7, 18))
+    True
+    >>> i1.intersects(Interval(25, 29))
+    False
+
+    >>> print Session().query(Interval).filter(Interval.contains(15))
+    SELECT interval.id AS interval_id, interval.start AS interval_start,
+    interval."end" AS interval_end
+    FROM interval
+    WHERE interval.start <= :start_1 AND interval."end" > :end_1
+
+    >>> ia = aliased(Interval)
+    >>> print Session().query(Interval, ia).filter(Interval.intersects(ia))
+    SELECT interval.id AS interval_id, interval.start AS interval_start,
+    interval."end" AS interval_end, interval_1.id AS interval_1_id,
+    interval_1.start AS interval_1_start, interval_1."end" AS interval_1_end
+    FROM interval, interval AS interval_1
+    WHERE interval.start <= interval_1.start
+        AND interval."end" > interval_1.start
+        OR interval.start <= interval_1."end"
+        AND interval."end" > interval_1."end"
+
+Defining Expression Behavior Distinct from Attribute Behavior
+--------------------------------------------------------------
+
+Our usage of the ``&`` and ``|`` bitwise operators above was
+fortunate, considering our functions operated on two boolean values to
+return a new one.   In many cases, the construction of an in-Python
+function and a SQLAlchemy SQL expression have enough differences that
+two separate Python expressions should be defined.  The
+:mod:`~sqlalchemy.ext.hybrid` decorators define the
+:meth:`.hybrid_property.expression` modifier for this purpose.   As an
+example we'll define the radius of the interval, which requires the
+usage of the absolute value function::
+
+    from sqlalchemy import func
+
+    class Interval(object):
+        # ...
+
+        @hybrid_property
+        def radius(self):
+            return abs(self.length) / 2
+
+        @radius.expression
+        def radius(cls):
+            return func.abs(cls.length) / 2
+
+Above the Python function ``abs()`` is used for instance-level
+operations, the SQL function ``ABS()`` is used via the :attr:`.func`
+object for class-level expressions::
+
+    >>> i1.radius
+    2
+
+    >>> print Session().query(Interval).filter(Interval.radius > 5)
+    SELECT interval.id AS interval_id, interval.start AS interval_start,
+        interval."end" AS interval_end
+    FROM interval
+    WHERE abs(interval."end" - interval.start) / :abs_1 > :param_1
+
+Defining Setters
+----------------
+
+Hybrid properties can also define setter methods.  If we wanted
+``length`` above, when set, to modify the endpoint value::
+
+    class Interval(object):
+        # ...
+
+        @hybrid_property
+        def length(self):
+            return self.end - self.start
+
+        @length.setter
+        def length(self, value):
+            self.end = self.start + value
+
+The ``length(self, value)`` method is now called upon set::
+
+    >>> i1 = Interval(5, 10)
+    >>> i1.length
+    5
+    >>> i1.length = 12
+    >>> i1.end
+    17
+
+Working with Relationships
+--------------------------
+
+There's no essential difference when creating hybrids that work with
+related objects as opposed to column-based data. The need for distinct
+expressions tends to be greater.  Two variants of we'll illustrate
+are the "join-dependent" hybrid, and the "correlated subquery" hybrid.
+
+Join-Dependent Relationship Hybrid
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Consider the following declarative
+mapping which relates a ``User`` to a ``SavingsAccount``::
+
+    from sqlalchemy import Column, Integer, ForeignKey, Numeric, String
+    from sqlalchemy.orm import relationship
+    from sqlalchemy.ext.declarative import declarative_base
+    from sqlalchemy.ext.hybrid import hybrid_property
+
+    Base = declarative_base()
+
+    class SavingsAccount(Base):
+        __tablename__ = 'account'
+        id = Column(Integer, primary_key=True)
+        user_id = Column(Integer, ForeignKey('user.id'), nullable=False)
+        balance = Column(Numeric(15, 5))
+
+    class User(Base):
+        __tablename__ = 'user'
+        id = Column(Integer, primary_key=True)
+        name = Column(String(100), nullable=False)
+
+        accounts = relationship("SavingsAccount", backref="owner")
+
+        @hybrid_property
+        def balance(self):
+            if self.accounts:
+                return self.accounts[0].balance
+            else:
+                return None
+
+        @balance.setter
+        def balance(self, value):
+            if not self.accounts:
+                account = Account(owner=self)
+            else:
+                account = self.accounts[0]
+            account.balance = value
+
+        @balance.expression
+        def balance(cls):
+            return SavingsAccount.balance
+
+The above hybrid property ``balance`` works with the first
+``SavingsAccount`` entry in the list of accounts for this user.   The
+in-Python getter/setter methods can treat ``accounts`` as a Python
+list available on ``self``.
+
+However, at the expression level, it's expected that the ``User`` class will
+be used in an appropriate context such that an appropriate join to
+``SavingsAccount`` will be present::
+
+    >>> print Session().query(User, User.balance).\\
+    ...     join(User.accounts).filter(User.balance > 5000)
+    SELECT "user".id AS user_id, "user".name AS user_name,
+    account.balance AS account_balance
+    FROM "user" JOIN account ON "user".id = account.user_id
+    WHERE account.balance > :balance_1
+
+Note however, that while the instance level accessors need to worry
+about whether ``self.accounts`` is even present, this issue expresses
+itself differently at the SQL expression level, where we basically
+would use an outer join::
+
+    >>> from sqlalchemy import or_
+    >>> print (Session().query(User, User.balance).outerjoin(User.accounts).
+    ...         filter(or_(User.balance < 5000, User.balance == None)))
+    SELECT "user".id AS user_id, "user".name AS user_name,
+    account.balance AS account_balance
+    FROM "user" LEFT OUTER JOIN account ON "user".id = account.user_id
+    WHERE account.balance <  :balance_1 OR account.balance IS NULL
+
+Correlated Subquery Relationship Hybrid
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+We can, of course, forego being dependent on the enclosing query's usage
+of joins in favor of the correlated subquery, which can portably be packed
+into a single column expression. A correlated subquery is more portable, but
+often performs more poorly at the SQL level. Using the same technique
+illustrated at :ref:`mapper_column_property_sql_expressions`,
+we can adjust our ``SavingsAccount`` example to aggregate the balances for
+*all* accounts, and use a correlated subquery for the column expression::
+
+    from sqlalchemy import Column, Integer, ForeignKey, Numeric, String
+    from sqlalchemy.orm import relationship
+    from sqlalchemy.ext.declarative import declarative_base
+    from sqlalchemy.ext.hybrid import hybrid_property
+    from sqlalchemy import select, func
+
+    Base = declarative_base()
+
+    class SavingsAccount(Base):
+        __tablename__ = 'account'
+        id = Column(Integer, primary_key=True)
+        user_id = Column(Integer, ForeignKey('user.id'), nullable=False)
+        balance = Column(Numeric(15, 5))
+
+    class User(Base):
+        __tablename__ = 'user'
+        id = Column(Integer, primary_key=True)
+        name = Column(String(100), nullable=False)
+
+        accounts = relationship("SavingsAccount", backref="owner")
+
+        @hybrid_property
+        def balance(self):
+            return sum(acc.balance for acc in self.accounts)
+
+        @balance.expression
+        def balance(cls):
+            return select([func.sum(SavingsAccount.balance)]).\\
+                    where(SavingsAccount.user_id==cls.id).\\
+                    label('total_balance')
+
+The above recipe will give us the ``balance`` column which renders
+a correlated SELECT::
+
+    >>> print s.query(User).filter(User.balance > 400)
+    SELECT "user".id AS user_id, "user".name AS user_name
+    FROM "user"
+    WHERE (SELECT sum(account.balance) AS sum_1
+    FROM account
+    WHERE account.user_id = "user".id) > :param_1
+
+.. _hybrid_custom_comparators:
+
+Building Custom Comparators
+---------------------------
+
+The hybrid property also includes a helper that allows construction of
+custom comparators. A comparator object allows one to customize the
+behavior of each SQLAlchemy expression operator individually.  They
+are useful when creating custom types that have some highly
+idiosyncratic behavior on the SQL side.
+
+The example class below allows case-insensitive comparisons on the attribute
+named ``word_insensitive``::
+
+    from sqlalchemy.ext.hybrid import Comparator, hybrid_property
+    from sqlalchemy import func, Column, Integer, String
+    from sqlalchemy.orm import Session
+    from sqlalchemy.ext.declarative import declarative_base
+
+    Base = declarative_base()
+
+    class CaseInsensitiveComparator(Comparator):
+        def __eq__(self, other):
+            return func.lower(self.__clause_element__()) == func.lower(other)
+
+    class SearchWord(Base):
+        __tablename__ = 'searchword'
+        id = Column(Integer, primary_key=True)
+        word = Column(String(255), nullable=False)
+
+        @hybrid_property
+        def word_insensitive(self):
+            return self.word.lower()
+
+        @word_insensitive.comparator
+        def word_insensitive(cls):
+            return CaseInsensitiveComparator(cls.word)
+
+Above, SQL expressions against ``word_insensitive`` will apply the ``LOWER()``
+SQL function to both sides::
+
+    >>> print Session().query(SearchWord).filter_by(word_insensitive="Trucks")
+    SELECT searchword.id AS searchword_id, searchword.word AS searchword_word
+    FROM searchword
+    WHERE lower(searchword.word) = lower(:lower_1)
+
+The ``CaseInsensitiveComparator`` above implements part of the
+:class:`.ColumnOperators` interface.   A "coercion" operation like
+lowercasing can be applied to all comparison operations (i.e. ``eq``,
+``lt``, ``gt``, etc.) using :meth:`.Operators.operate`::
+
+    class CaseInsensitiveComparator(Comparator):
+        def operate(self, op, other):
+            return op(func.lower(self.__clause_element__()), func.lower(other))
+
+Hybrid Value Objects
+--------------------
+
+Note in our previous example, if we were to compare the
+``word_insensitive`` attribute of a ``SearchWord`` instance to a plain
+Python string, the plain Python string would not be coerced to lower
+case - the ``CaseInsensitiveComparator`` we built, being returned by
+``@word_insensitive.comparator``, only applies to the SQL side.
+
+A more comprehensive form of the custom comparator is to construct a
+*Hybrid Value Object*. This technique applies the target value or
+expression to a value object which is then returned by the accessor in
+all cases.   The value object allows control of all operations upon
+the value as well as how compared values are treated, both on the SQL
+expression side as well as the Python value side.   Replacing the
+previous ``CaseInsensitiveComparator`` class with a new
+``CaseInsensitiveWord`` class::
+
+    class CaseInsensitiveWord(Comparator):
+        "Hybrid value representing a lower case representation of a word."
+
+        def __init__(self, word):
+            if isinstance(word, basestring):
+                self.word = word.lower()
+            elif isinstance(word, CaseInsensitiveWord):
+                self.word = word.word
+            else:
+                self.word = func.lower(word)
+
+        def operate(self, op, other):
+            if not isinstance(other, CaseInsensitiveWord):
+                other = CaseInsensitiveWord(other)
+            return op(self.word, other.word)
+
+        def __clause_element__(self):
+            return self.word
+
+        def __str__(self):
+            return self.word
+
+        key = 'word'
+        "Label to apply to Query tuple results"
+
+Above, the ``CaseInsensitiveWord`` object represents ``self.word``,
+which may be a SQL function, or may be a Python native.   By
+overriding ``operate()`` and ``__clause_element__()`` to work in terms
+of ``self.word``, all comparison operations will work against the
+"converted" form of ``word``, whether it be SQL side or Python side.
+Our ``SearchWord`` class can now deliver the ``CaseInsensitiveWord``
+object unconditionally from a single hybrid call::
+
+    class SearchWord(Base):
+        __tablename__ = 'searchword'
+        id = Column(Integer, primary_key=True)
+        word = Column(String(255), nullable=False)
+
+        @hybrid_property
+        def word_insensitive(self):
+            return CaseInsensitiveWord(self.word)
+
+The ``word_insensitive`` attribute now has case-insensitive comparison
+behavior universally, including SQL expression vs. Python expression
+(note the Python value is converted to lower case on the Python side
+here)::
+
+    >>> print Session().query(SearchWord).filter_by(word_insensitive="Trucks")
+    SELECT searchword.id AS searchword_id, searchword.word AS searchword_word
+    FROM searchword
+    WHERE lower(searchword.word) = :lower_1
+
+SQL expression versus SQL expression::
+
+    >>> sw1 = aliased(SearchWord)
+    >>> sw2 = aliased(SearchWord)
+    >>> print Session().query(
+    ...                    sw1.word_insensitive,
+    ...                    sw2.word_insensitive).\\
+    ...                        filter(
+    ...                            sw1.word_insensitive > sw2.word_insensitive
+    ...                        )
+    SELECT lower(searchword_1.word) AS lower_1,
+    lower(searchword_2.word) AS lower_2
+    FROM searchword AS searchword_1, searchword AS searchword_2
+    WHERE lower(searchword_1.word) > lower(searchword_2.word)
+
+Python only expression::
+
+    >>> ws1 = SearchWord(word="SomeWord")
+    >>> ws1.word_insensitive == "sOmEwOrD"
+    True
+    >>> ws1.word_insensitive == "XOmEwOrX"
+    False
+    >>> print ws1.word_insensitive
+    someword
+
+The Hybrid Value pattern is very useful for any kind of value that may
+have multiple representations, such as timestamps, time deltas, units
+of measurement, currencies and encrypted passwords.

+
+.. _hybrid_transformers:
+
+Building Transformers
+----------------------
+
+A *transformer* is an object which can receive a :class:`.Query`
+object and return a new one.   The :class:`.Query` object includes a
+method :meth:`.with_transformation` that returns a new :class:`.Query`
+transformed by the given function.
+
+We can combine this with the :class:`.Comparator` class to produce one type
+of recipe which can both set up the FROM clause of a query as well as assign
+filtering criterion.
+
+Consider a mapped class ``Node``, which assembles using adjacency list
+into a hierarchical tree pattern::
+
+    from sqlalchemy import Column, Integer, ForeignKey
+    from sqlalchemy.orm import relationship
+    from sqlalchemy.ext.declarative import declarative_base
+    Base = declarative_base()
+
+    class Node(Base):
+        __tablename__ = 'node'
+        id =Column(Integer, primary_key=True)
+        parent_id = Column(Integer, ForeignKey('node.id'))
+        parent = relationship("Node", remote_side=id)
+
+Suppose we wanted to add an accessor ``grandparent``.  This would
+return the ``parent`` of ``Node.parent``.  When we have an instance of
+``Node``, this is simple::
+
+    from sqlalchemy.ext.hybrid import hybrid_property
+
+    class Node(Base):
+        # ...
+
+        @hybrid_property
+        def grandparent(self):
+            return self.parent.parent
+
+For the expression, things are not so clear.   We'd need to construct
+a :class:`.Query` where we :meth:`~.Query.join` twice along
+``Node.parent`` to get to the ``grandparent``.   We can instead return
+a transforming callable that we'll combine with the
+:class:`.Comparator` class to receive any :class:`.Query` object, and
+return a new one that's joined to the ``Node.parent`` attribute and
+filtered based on the given criterion::
+
+    from sqlalchemy.ext.hybrid import Comparator
+
+    class GrandparentTransformer(Comparator):
+        def operate(self, op, other):
+            def transform(q):
+                cls = self.__clause_element__()
+                parent_alias = aliased(cls)
+                return q.join(parent_alias, cls.parent).\\
+                            filter(op(parent_alias.parent, other))
+            return transform
+
+    Base = declarative_base()
+
+    class Node(Base):
+        __tablename__ = 'node'
+        id =Column(Integer, primary_key=True)
+        parent_id = Column(Integer, ForeignKey('node.id'))
+        parent = relationship("Node", remote_side=id)
+
+        @hybrid_property
+        def grandparent(self):
+            return self.parent.parent
+
+        @grandparent.comparator
+        def grandparent(cls):
+            return GrandparentTransformer(cls)
+
+The ``GrandparentTransformer`` overrides the core
+:meth:`.Operators.operate` method at the base of the
+:class:`.Comparator` hierarchy to return a query-transforming
+callable, which then runs the given comparison operation in a
+particular context. Such as, in the example above, the ``operate``
+method is called, given the :attr:`.Operators.eq` callable as well as
+the right side of the comparison ``Node(id=5)``.  A function
+``transform`` is then returned which will transform a :class:`.Query`
+first to join to ``Node.parent``, then to compare ``parent_alias``
+using :attr:`.Operators.eq` against the left and right sides, passing
+into :class:`.Query.filter`:
+
+.. sourcecode:: pycon+sql
+
+    >>> from sqlalchemy.orm import Session
+    >>> session = Session()
+    {sql}>>> session.query(Node).\\
+    ...        with_transformation(Node.grandparent==Node(id=5)).\\
+    ...        all()
+    SELECT node.id AS node_id, node.parent_id AS node_parent_id
+    FROM node JOIN node AS node_1 ON node_1.id = node.parent_id
+    WHERE :param_1 = node_1.parent_id
+    {stop}
+
+We can modify the pattern to be more verbose but flexible by separating
+the "join" step from the "filter" step.  The tricky part here is ensuring
+that successive instances of ``GrandparentTransformer`` use the same
+:class:`.AliasedClass` object against ``Node``.  Below we use a simple
+memoizing approach that associates a ``GrandparentTransformer``
+with each class::
+
+    class Node(Base):
+
+        # ...
+
+        @grandparent.comparator
+        def grandparent(cls):
+            # memoize a GrandparentTransformer
+            # per class
+            if '_gp' not in cls.__dict__:
+                cls._gp = GrandparentTransformer(cls)
+            return cls._gp
+
+    class GrandparentTransformer(Comparator):
+
+        def __init__(self, cls):
+            self.parent_alias = aliased(cls)
+
+        @property
+        def join(self):
+            def go(q):
+                return q.join(self.parent_alias, Node.parent)
+            return go
+
+        def operate(self, op, other):
+            return op(self.parent_alias.parent, other)
+
+.. sourcecode:: pycon+sql
+
+    {sql}>>> session.query(Node).\\
+    ...            with_transformation(Node.grandparent.join).\\
+    ...            filter(Node.grandparent==Node(id=5))
+    SELECT node.id AS node_id, node.parent_id AS node_parent_id
+    FROM node JOIN node AS node_1 ON node_1.id = node.parent_id
+    WHERE :param_1 = node_1.parent_id
+    {stop}
+
+The "transformer" pattern is an experimental pattern that starts
+to make usage of some functional programming paradigms.
+While it's only recommended for advanced and/or patient developers,
+there's probably a whole lot of amazing things it can be used for.

+    import json
+
+    class JSONEncodedDict(TypeDecorator):
+        "Represents an immutable structure as a json-encoded string."

+            if value is not None:
+                value = json.loads(value)
+            return value
+
+The usage of ``json`` is only for the purposes of example. The
+:mod:`sqlalchemy.ext.mutable` extension can be used
+with any type whose target Python type may be mutable, including
+:class:`.PickleType`, :class:`.postgresql.ARRAY`, etc.
+
+When using the :mod:`sqlalchemy.ext.mutable` extension, the value itself
+tracks all parents which reference it.  Below, we illustrate the a simple
+version of the :class:`.MutableDict` dictionary object, which applies
+the :class:`.Mutable` mixin to a plain Python dictionary::
+
+    from sqlalchemy.ext.mutable import Mutable
+
+    class MutableDict(Mutable, dict):
+        @classmethod
+        def coerce(cls, key, value):
+            "Convert plain dictionaries to MutableDict."
+
+            if not isinstance(value, MutableDict):
+                if isinstance(value, dict):
+                    return MutableDict(value)
+
+                # this call will raise ValueError
+                return Mutable.coerce(key, value)
+            else:
+                return value
+
+        def __setitem__(self, key, value):
+            "Detect dictionary set events and emit change events."
+
+            dict.__setitem__(self, key, value)
+            self.changed()
+
+        def __delitem__(self, key):
+            "Detect dictionary del events and emit change events."
+
+            dict.__delitem__(self, key)
+            self.changed()
+
+The above dictionary class takes the approach of subclassing the Python
+built-in ``dict`` to produce a dict
+subclass which routes all mutation events through ``__setitem__``.  There are
+variants on this approach, such as subclassing ``UserDict.UserDict`` or
+``collections.MutableMapping``; the part that's important to this example is
+that the :meth:`.Mutable.changed` method is called whenever an in-place
+change to the datastructure takes place.
+
+We also redefine the :meth:`.Mutable.coerce` method which will be used to
+convert any values that are not instances of ``MutableDict``, such
+as the plain dictionaries returned by the ``json`` module, into the
+appropriate type.  Defining this method is optional; we could just as well
+created our ``JSONEncodedDict`` such that it always returns an instance
+of ``MutableDict``, and additionally ensured that all calling code
+uses ``MutableDict`` explicitly.  When :meth:`.Mutable.coerce` is not
+overridden, any values applied to a parent object which are not instances
+of the mutable type will raise a ``ValueError``.
+
+Our new ``MutableDict`` type offers a class method
+:meth:`~.Mutable.as_mutable` which we can use within column metadata
+to associate with types. This method grabs the given type object or
+class and associates a listener that will detect all future mappings
+of this type, applying event listening instrumentation to the mapped
+attribute. Such as, with classical table metadata::
+
+    from sqlalchemy import Table, Column, Integer
+
+    my_data = Table('my_data', metadata,
+        Column('id', Integer, primary_key=True),
+        Column('data', MutableDict.as_mutable(JSONEncodedDict))
+    )
+
+Above, :meth:`~.Mutable.as_mutable` returns an instance of ``JSONEncodedDict``
+(if the type object was not an instance already), which will intercept any
+attributes which are mapped against this type.  Below we establish a simple
+mapping against the ``my_data`` table::
+
+    from sqlalchemy import mapper
+
+    class MyDataClass(object):
+        pass
+
+    # associates mutation listeners with MyDataClass.data
+    mapper(MyDataClass, my_data)
+
+The ``MyDataClass.data`` member will now be notified of in place changes
+to its value.
+
+There's no difference in usage when using declarative::
+
+    from sqlalchemy.ext.declarative import declarative_base
+
+    Base = declarative_base()
+
+    class MyDataClass(Base):
+        __tablename__ = 'my_data'
+        id = Column(Integer, primary_key=True)
+        data = Column(MutableDict.as_mutable(JSONEncodedDict))
+
+Any in-place changes to the ``MyDataClass.data`` member
+will flag the attribute as "dirty" on the parent object::
+
+    >>> from sqlalchemy.orm import Session
+
+    >>> sess = Session()
+    >>> m1 = MyDataClass(data={'value1':'foo'})
+    >>> sess.add(m1)
+    >>> sess.commit()
+
+    >>> m1.data['value1'] = 'bar'
+    >>> assert m1 in sess.dirty
+    True
+
+The ``MutableDict`` can be associated with all future instances
+of ``JSONEncodedDict`` in one step, using
+:meth:`~.Mutable.associate_with`.  This is similar to
+:meth:`~.Mutable.as_mutable` except it will intercept all occurrences
+of ``MutableDict`` in all mappings unconditionally, without
+the need to declare it individually::
+
+    MutableDict.associate_with(JSONEncodedDict)
+
+    class MyDataClass(Base):
+        __tablename__ = 'my_data'
+        id = Column(Integer, primary_key=True)
+        data = Column(JSONEncodedDict)
+
+
+Supporting Pickling
+--------------------
+
+The key to the :mod:`sqlalchemy.ext.mutable` extension relies upon the
+placement of a ``weakref.WeakKeyDictionary`` upon the value object, which
+stores a mapping of parent mapped objects keyed to the attribute name under
+which they are associated with this value. ``WeakKeyDictionary`` objects are
+not picklable, due to the fact that they contain weakrefs and function
+callbacks. In our case, this is a good thing, since if this dictionary were
+picklable, it could lead to an excessively large pickle size for our value
+objects that are pickled by themselves outside of the context of the parent.
+The developer responsibility here is only to provide a ``__getstate__`` method
+that excludes the :meth:`~MutableBase._parents` collection from the pickle
+stream::
+
+    class MyMutableType(Mutable):
+        def __getstate__(self):
+            d = self.__dict__.copy()
+            d.pop('_parents', None)
+            return d
+
+With our dictionary example, we need to return the contents of the dict itself
+(and also restore them on __setstate__)::
+
+    class MutableDict(Mutable, dict):
+        # ....
+
+        def __getstate__(self):
+            return dict(self)
+
+        def __setstate__(self, state):
+            self.update(state)
+
+In the case that our mutable value object is pickled as it is attached to one
+or more parent objects that are also part of the pickle, the :class:`.Mutable`
+mixin will re-establish the :attr:`.Mutable._parents` collection on each value
+object as the owning parents themselves are unpickled.
+
+.. _mutable_composites:
+
+Establishing Mutability on Composites
+=====================================
+
+Composites are a special ORM feature which allow a single scalar attribute to
+be assigned an object value which represents information "composed" from one
+or more columns from the underlying mapped table. The usual example is that of
+a geometric "point", and is introduced in :ref:`mapper_composite`.
+
+.. versionchanged:: 0.7
+    The internals of :func:`.orm.composite` have been
+    greatly simplified and in-place mutation detection is no longer enabled by
+    default; instead, the user-defined value must detect changes on its own and
+    propagate them to all owning parents. The :mod:`sqlalchemy.ext.mutable`
+    extension provides the helper class :class:`.MutableComposite`, which is a
+    slight variant on the :class:`.Mutable` class.
+
+As is the case with :class:`.Mutable`, the user-defined composite class
+subclasses :class:`.MutableComposite` as a mixin, and detects and delivers
+change events to its parents via the :meth:`.MutableComposite.changed` method.
+In the case of a composite class, the detection is usually via the usage of
+Python descriptors (i.e. ``@property``), or alternatively via the special
+Python method ``__setattr__()``. Below we expand upon the ``Point`` class
+introduced in :ref:`mapper_composite` to subclass :class:`.MutableComposite`
+and to also route attribute set events via ``__setattr__`` to the
+:meth:`.MutableComposite.changed` method::
+
+    from sqlalchemy.ext.mutable import MutableComposite
+
+    class Point(MutableComposite):
+        def __init__(self, x, y):
+            self.x = x
+            self.y = y
+
+        def __setattr__(self, key, value):
+            "Intercept set events"
+
+            # set the attribute
+            object.__setattr__(self, key, value)
+
+            # alert all parents to the change
+            self.changed()
+
+        def __composite_values__(self):
+            return self.x, self.y
+
+        def __eq__(self, other):
+            return isinstance(other, Point) and \\
+                other.x == self.x and \\
+                other.y == self.y
+
+        def __ne__(self, other):
+            return not self.__eq__(other)
+
+The :class:`.MutableComposite` class uses a Python metaclass to automatically
+establish listeners for any usage of :func:`.orm.composite` that specifies our
+``Point`` type. Below, when ``Point`` is mapped to the ``Vertex`` class,
+listeners are established which will route change events from ``Point``
+objects to each of the ``Vertex.start`` and ``Vertex.end`` attributes::
+
+    from sqlalchemy.orm import composite, mapper
+    from sqlalchemy import Table, Column
+
+    vertices = Table('vertices', metadata,
+        Column('id', Integer, primary_key=True),
+        Column('x1', Integer),
+        Column('y1', Integer),
+        Column('x2', Integer),
+        Column('y2', Integer),
+        )
+
+    class Vertex(object):
+        pass
+
+    mapper(Vertex, vertices, properties={
+        'start': composite(Point, vertices.c.x1, vertices.c.y1),
+        'end': composite(Point, vertices.c.x2, vertices.c.y2)
+    })
+
+Any in-place changes to the ``Vertex.start`` or ``Vertex.end`` members
+will flag the attribute as "dirty" on the parent object::
+
+    >>> from sqlalchemy.orm import Session
+
+    >>> sess = Session()
+    >>> v1 = Vertex(start=Point(3, 4), end=Point(12, 15))
+    >>> sess.add(v1)
+    >>> sess.commit()
+
+    >>> v1.end.x = 8
+    >>> assert v1 in sess.dirty
+    True
+
+Coercing Mutable Composites
+---------------------------
+
+The :meth:`.MutableBase.coerce` method is also supported on composite types.
+In the case of :class:`.MutableComposite`, the :meth:`.MutableBase.coerce`
+method is only called for attribute set operations, not load operations.
+Overriding the :meth:`.MutableBase.coerce` method is essentially equivalent
+to using a :func:`.validates` validation routine for all attributes which
+make use of the custom composite type::
+
+    class Point(MutableComposite):
+        # other Point methods
+        # ...
+
+        def coerce(cls, key, value):
+            if isinstance(value, tuple):
+                value = Point(*value)
+            elif not isinstance(value, Point):
+                raise ValueError("tuple or Point expected")
+            return value
+
+.. versionadded:: 0.7.10,0.8.0b2
+    Support for the :meth:`.MutableBase.coerce` method in conjunction with
+    objects of type :class:`.MutableComposite`.
+
+Supporting Pickling
+--------------------
+
+As is the case with :class:`.Mutable`, the :class:`.MutableComposite` helper
+class uses a ``weakref.WeakKeyDictionary`` available via the
+:meth:`MutableBase._parents` attribute which isn't picklable. If we need to
+pickle instances of ``Point`` or its owning class ``Vertex``, we at least need
+to define a ``__getstate__`` that doesn't include the ``_parents`` dictionary.
+Below we define both a ``__getstate__`` and a ``__setstate__`` that package up
+the minimal form of our ``Point`` class::
+
+    class Point(MutableComposite):
+        # ...
+
+        def __getstate__(self):
+            return self.x, self.y
+
+        def __setstate__(self, state):
+            self.x, self.y = state
+
+As with :class:`.Mutable`, the :class:`.MutableComposite` augments the
+pickling process of the parent's object-relational state so that the
+:meth:`MutableBase._parents` collection is restored to all ``Point`` objects.

+"""A custom list that manages index/position information for contained
+elements.
+
+:author: Jason Kirtland
+
+``orderinglist`` is a helper for mutable ordered relationships.  It will
+intercept list operations performed on a :func:`.relationship`-managed
+collection and
+automatically synchronize changes in list position onto a target scalar
+attribute.
+
+Example: A ``slide`` table, where each row refers to zero or more entries
+in a related ``bullet`` table.   The bullets within a slide are
+displayed in order based on the value of the ``position`` column in the
+``bullet`` table.   As entries are reordered in memory, the value of the
+``position`` attribute should be updated to reflect the new sort order::
+
+
+    Base = declarative_base()
+
+    class Slide(Base):
+        __tablename__ = 'slide'
+
+        id = Column(Integer, primary_key=True)
+        name = Column(String)
+
+        bullets = relationship("Bullet", order_by="Bullet.position")
+
+    class Bullet(Base):
+        __tablename__ = 'bullet'
+        id = Column(Integer, primary_key=True)
+        slide_id = Column(Integer, ForeignKey('slide.id'))
+        position = Column(Integer)
+        text = Column(String)
+
+The standard relationship mapping will produce a list-like attribute on each
+``Slide`` containing all related ``Bullet`` objects,
+but coping with changes in ordering is not handled automatically.
+When appending a ``Bullet`` into ``Slide.bullets``, the ``Bullet.position``
+attribute will remain unset until manually assigned.   When the ``Bullet``
+is inserted into the middle of the list, the following ``Bullet`` objects
+will also need to be renumbered.
+
+The :class:`.OrderingList` object automates this task, managing the
+``position`` attribute on all ``Bullet`` objects in the collection.  It is
+constructed using the :func:`.ordering_list` factory::
+
+    from sqlalchemy.ext.orderinglist import ordering_list
+
+    Base = declarative_base()
+
+    class Slide(Base):
+        __tablename__ = 'slide'
+
+        id = Column(Integer, primary_key=True)
+        name = Column(String)
+
+        bullets = relationship("Bullet", order_by="Bullet.position",
+                                collection_class=ordering_list('position'))
+
+    class Bullet(Base):
+        __tablename__ = 'bullet'
+        id = Column(Integer, primary_key=True)
+        slide_id = Column(Integer, ForeignKey('slide.id'))
+        position = Column(Integer)
+        text = Column(String)
+
+With the above mapping the ``Bullet.position`` attribute is managed::
+
+    s = Slide()
+    s.bullets.append(Bullet())
+    s.bullets.append(Bullet())
+    s.bullets[1].position
+    >>> 1
+    s.bullets.insert(1, Bullet())
+    s.bullets[2].position
+    >>> 2
+
+The :class:`.OrderingList` construct only works with **changes** to a
+collection, and not the initial load from the database, and requires that the
+list be sorted when loaded.  Therefore, be sure to specify ``order_by`` on the
+:func:`.relationship` against the target ordering attribute, so that the
+ordering is correct when first loaded.
+
+.. warning::
+
+  :class:`.OrderingList` only provides limited functionality when a primary
+  key column or unique column is the target of the sort.  Operations
+  that are unsupported or are problematic include:
+
+    * two entries must trade values.  This is not supported directly in the
+      case of a primary key or unique constraint because it means at least
+      one row would need to be temporarily removed first, or changed to
+      a third, neutral value while the switch occurs.
+
+    * an entry must be deleted in order to make room for a new entry.
+      SQLAlchemy's unit of work performs all INSERTs before DELETEs within a
+      single flush.  In the case of a primary key, it will trade
+      an INSERT/DELETE of the same primary key for an UPDATE statement in order
+      to lessen the impact of this limitation, however this does not take place
+      for a UNIQUE column.
+      A future feature will allow the "DELETE before INSERT" behavior to be
+      possible, allevating this limitation, though this feature will require
+      explicit configuration at the mapper level for sets of columns that
+      are to be handled in this way.
+
+:func:`.ordering_list` takes the name of the related object's ordering
+attribute as an argument.  By default, the zero-based integer index of the
+object's position in the :func:`.ordering_list` is synchronized with the
+ordering attribute: index 0 will get position 0, index 1 position 1, etc.  To
+start numbering at 1 or some other integer, provide ``count_from=1``.

+"""Serializer/Deserializer objects for usage with SQLAlchemy query structures,
+allowing "contextual" deserialization.
+
+Any SQLAlchemy query structure, either based on sqlalchemy.sql.*
+or sqlalchemy.orm.* can be used.  The mappers, Tables, Columns, Session
+etc. which are referenced by the structure are not persisted in serialized
+form, but are instead re-associated with the query structure
+when it is deserialized.
+
+Usage is nearly the same as that of the standard Python pickle module::
+
+    from sqlalchemy.ext.serializer import loads, dumps
+    metadata = MetaData(bind=some_engine)
+    Session = scoped_session(sessionmaker())
+
+    # ... define mappers
+
+    query = Session.query(MyClass).
+        filter(MyClass.somedata=='foo').order_by(MyClass.sortkey)
+
+    # pickle the query
+    serialized = dumps(query)
+
+    # unpickle.  Pass in metadata + scoped_session
+    query2 = loads(serialized, metadata, Session)
+
+    print query2.all()
+
+Similar restrictions as when using raw pickle apply; mapped classes must be
+themselves be pickleable, meaning they are importable from a module-level
+namespace.
+
+The serializer module is only appropriate for query structures.  It is not
+needed for:
+
+* instances of user-defined classes.   These contain no references to engines,
+  sessions or expression constructs in the typical case and can be serialized
+  directly.
+
+* Table metadata that is to be loaded entirely from the serialized structure
+  (i.e. is not already declared in the application).   Regular
+  pickle.loads()/dumps() can be used to fully dump any ``MetaData`` object,
+  typically one which was reflected from an existing database at some previous
+  point in time.  The serializer module is specifically for the opposite case,
+  where the Table metadata is already present in memory.

+"""The inspection module provides the :func:`.inspect` function,
+which delivers runtime information about a wide variety
+of SQLAlchemy objects, both within the Core as well as the
+ORM.
+
+The :func:`.inspect` function is the entry point to SQLAlchemy's
+public API for viewing the configuration and construction
+of in-memory objects.   Depending on the type of object
+passed to :func:`.inspect`, the return value will either be
+a related object which provides a known interface, or in many
+cases it will return the object itself.
+
+The rationale for :func:`.inspect` is twofold.  One is that
+it replaces the need to be aware of a large variety of "information
+getting" functions in SQLAlchemy, such as :meth:`.Inspector.from_engine`,
+:func:`.orm.attributes.instance_state`, :func:`.orm.class_mapper`,
+and others.    The other is that the return value of :func:`.inspect`
+is guaranteed to obey a documented API, thus allowing third party
+tools which build on top of SQLAlchemy configurations to be constructed
+in a forwards-compatible way.
+
+.. versionadded:: 0.8 The :func:`.inspect` system is introduced

+
+    All of the standard connection :class:`~sqlalchemy.pool.Pool` types can
+    accept event listeners for key connection lifecycle events:
+    creation, pool check-out and check-in.  There are no events fired
+    when a connection closes.
+
+    For any given DB-API connection, there will be one ``connect``
+    event, `n` number of ``checkout`` events, and either `n` or `n - 1`
+    ``checkin`` events.  (If a ``Connection`` is detached from its
+    pool via the ``detach()`` method, it won't be checked back in.)
+
+    These are low-level events for low-level objects: raw Python
+    DB-API connections, without the conveniences of the SQLAlchemy
+    ``Connection`` wrapper, ``Dialect`` services or ``ClauseElement``
+    execution.  If you execute SQL through the connection, explicitly
+    closing all cursors and other resources is recommended.
+
+    Events also receive a ``_ConnectionRecord``, a long-lived internal
+    ``Pool`` object that basically represents a "slot" in the
+    connection pool.  ``_ConnectionRecord`` objects have one public
+    attribute of note: ``info``, a dictionary whose contents are
+    scoped to the lifetime of the DB-API connection managed by the
+    record.  You can use this shared storage area however you like.
+
+    There is no need to subclass ``PoolListener`` to handle events.
+    Any class that implements one or more of these methods can be used
+    as a pool listener.  The ``Pool`` will inspect the methods
+    provided by a listener object and add the listener to one or more
+    internal event queues based on its capabilities.  In terms of
+    efficiency and function call overhead, you're much better off only
+    providing implementations for the hooks you'll be using.

+
+"""Support for collections of mapped entities.
+
+The collections package supplies the machinery used to inform the ORM of
+collection membership changes.  An instrumentation via decoration approach is
+used, allowing arbitrary types (including built-ins) to be used as entity
+collections without requiring inheritance from a base class.
+
+Instrumentation decoration relays membership change events to the
+:class:`.CollectionAttributeImpl` that is currently managing the collection.
+The decorators observe function call arguments and return values, tracking
+entities entering or leaving the collection.  Two decorator approaches are
+provided.  One is a bundle of generic decorators that map function arguments
+and return values to events::
+
+  from sqlalchemy.orm.collections import collection
+  class MyClass(object):
+      # ...
+
+      @collection.adds(1)
+      def store(self, item):
+          self.data.append(item)
+
+      @collection.removes_return()
+      def pop(self):
+          return self.data.pop()
+
+
+The second approach is a bundle of targeted decorators that wrap appropriate
+append and remove notifiers around the mutation methods present in the
+standard Python ``list``, ``set`` and ``dict`` interfaces.  These could be
+specified in terms of generic decorator recipes, but are instead hand-tooled
+for increased efficiency.  The targeted decorators occasionally implement
+adapter-like behavior, such as mapping bulk-set methods (``extend``,
+``update``, ``__setslice__``, etc.) into the series of atomic mutation events
+that the ORM requires.
+
+The targeted decorators are used internally for automatic instrumentation of
+entity collection classes.  Every collection class goes through a
+transformation process roughly like so:
+
+1. If the class is a built-in, substitute a trivial sub-class
+2. Is this class already instrumented?
+3. Add in generic decorators
+4. Sniff out the collection interface through duck-typing
+5. Add targeted decoration to any undecorated interface method
+
+This process modifies the class at runtime, decorating methods and adding some
+bookkeeping properties.  This isn't possible (or desirable) for built-in
+classes like ``list``, so trivial sub-classes are substituted to hold
+decoration::
+
+  class InstrumentedList(list):
+      pass
+
+Collection classes can be specified in ``relationship(collection_class=)`` as
+types or a function that returns an instance.  Collection classes are
+inspected and instrumented during the mapper compilation phase.  The
+collection_class callable will be executed once to produce a specimen
+instance, and the type of that specimen will be instrumented.  Functions that
+return built-in types like ``lists`` will be adapted to produce instrumented
+instances.
+
+When extending a known type like ``list``, additional decorations are not
+generally not needed.  Odds are, the extension method will delegate to a
+method that's already instrumented.  For example::
+
+  class QueueIsh(list):
+     def push(self, item):
+         self.append(item)
+     def shift(self):
+         return self.pop(0)
+
+There's no need to decorate these methods.  ``append`` and ``pop`` are already
+instrumented as part of the ``list`` interface.  Decorating them would fire
+duplicate events, which should be avoided.
+
+The targeted decoration tries not to rely on other methods in the underlying
+collection class, but some are unavoidable.  Many depend on 'read' methods
+being present to properly instrument a 'write', for example, ``__setitem__``
+needs ``__getitem__``.  "Bulk" methods like ``update`` and ``extend`` may also
+reimplemented in terms of atomic appends and removes, so the ``extend``
+decoration will actually perform many ``append`` operations and not call the
+underlying method at all.
+
+Tight control over bulk operation and the firing of events is also possible by
+implementing the instrumentation internally in your methods.  The basic
+instrumentation package works under the general assumption that collection
+mutation will not raise unusual exceptions.  If you want to closely
+orchestrate append and remove events with exception management, internal
+instrumentation may be the answer.  Within your method,
+``collection_adapter(self)`` will retrieve an object that you can use for
+explicit control over triggering append and remove events.
+
+The owning object and :class:`.CollectionAttributeImpl` are also reachable
+through the adapter, allowing for some very sophisticated behavior.

+       refer to :func:`.event.listen` as well as
+       :class:`.MapperEvents`.
+
+    New extension classes subclass :class:`.MapperExtension` and are specified
+    using the ``extension`` mapper() argument, which is a single
+    :class:`.MapperExtension` or a list of such::
+
+        from sqlalchemy.orm.interfaces import MapperExtension
+
+        class MyExtension(MapperExtension):
+            def before_insert(self, mapper, connection, instance):
+                print "instance %s before insert !" % instance
+
+        m = mapper(User, users_table, extension=MyExtension())
+
+    A single mapper can maintain a chain of ``MapperExtension``
+    objects. When a particular mapping event occurs, the
+    corresponding method on each ``MapperExtension`` is invoked
+    serially, and each method has the ability to halt the chain
+    from proceeding further::
+
+        m = mapper(User, users_table, extension=[ext1, ext2, ext3])
+
+    Each ``MapperExtension`` method returns the symbol
+    EXT_CONTINUE by default.   This symbol generally means "move
+    to the next ``MapperExtension`` for processing".  For methods
+    that return objects like translated rows or new object
+    instances, EXT_CONTINUE means the result of the method
+    should be ignored.   In some cases it's required for a
+    default mapper activity to be performed, such as adding a
+    new instance to a result list.
+
+    The symbol EXT_STOP has significance within a chain
+    of ``MapperExtension`` objects that the chain will be stopped
+    when this symbol is returned.  Like EXT_CONTINUE, it also
+    has additional significance in some cases that a default
+    mapper activity will not be performed.

+    The listeners here support being established against

+    against that class.  If the "propagate=True" flag is passed
+    to event.listen(), the event will fire off for subclasses
+    of that class as well.
+
+    The Python ``type`` builtin is also accepted as a target,
+    which when used has the effect of events being emitted
+    for all classes.
+
+    Note the "propagate" flag here is defaulted to ``True``,

+"""Defines SQLAlchemy's system of class instrumentation.
+
+This module is usually not directly visible to user applications, but
+defines a large part of the ORM's interactivity.
+
+instrumentation.py deals with registration of end-user classes
+for state tracking.   It interacts closely with state.py
+and attributes.py which establish per-instance and per-class-attribute
+instrumentation, respectively.
+
+The class instrumentation system can be customized on a per-class
+or global basis using the :mod:`sqlalchemy.ext.instrumentation`
+module, which provides the means to build and specify
+alternate instrumentation forms.
+
+.. versionchanged: 0.8
+   The instrumentation extension system was moved out of the
+   ORM and into the external :mod:`sqlalchemy.ext.instrumentation`
+   package.  When that package is imported, it installs
+   itself within sqlalchemy.orm so that its more comprehensive
+   resolution mechanics take effect.

+        This function is typically used behind the scenes
+        via the Declarative extension.   When using Declarative,
+        many of the usual :func:`.mapper` arguments are handled
+        by the Declarative extension itself, including ``class_``,
+        ``local_table``, ``properties``, and  ``inherits``.
+        Other options are passed to :func:`.mapper` using
+        the ``__mapper_args__`` class variable::
+
+           class MyClass(Base):
+               __tablename__ = 'my_table'
+               id = Column(Integer, primary_key=True)
+               type = Column(String(50))
+               alt = Column("some_alt", Integer)
+
+               __mapper_args__ = {
+                   'polymorphic_on' : type
+               }
+
+
+        Explicit use of :func:`.mapper`
+        is often referred to as *classical mapping*.  The above
+        declarative example is equivalent in classical form to::
+
+            my_table = Table("my_table", metadata,
+                Column('id', Integer, primary_key=True),
+                Column('type', String(50)),

+
+            :ref:`classical_mapping` - discussion of direct usage of
+            :func:`.mapper`
+
+        :param class\_: The class to be mapped.  When using Declarative,
+          this argument is automatically passed as the declared class
+          itself.
+
+        :param local_table: The :class:`.Table` or other selectable
+           to which the class is mapped.  May be ``None`` if
+           this mapper inherits from another mapper using single-table
+           inheritance.   When using Declarative, this argument is
+           automatically passed by the extension, based on what
+           is configured via the ``__table__`` argument or via the
+           :class:`.Table` produced as a result of the ``__tablename__``
+           and :class:`.Column` arguments present.
+
+        :param always_refresh: If True, all query operations for this mapped
+           class will overwrite all data within object instances that already
+           exist within the session, erasing any in-memory changes with
+           whatever information was loaded from the database. Usage of this
+           flag is highly discouraged; as an alternative, see the method
+           :meth:`.Query.populate_existing`.
+
+        :param allow_partial_pks: Defaults to True.  Indicates that a
+           composite primary key with some NULL values should be considered as
+           possibly existing within the database. This affects whether a
+           mapper will assign an incoming row to an existing identity, as well
+           as if :meth:`.Session.merge` will check the database first for a
+           particular primary key value. A "partial primary key" can occur if
+           one has mapped to an OUTER JOIN, for example.
+
+        :param batch: Defaults to ``True``, indicating that save operations
+           of multiple entities can be batched together for efficiency.
+           Setting to False indicates
+           that an instance will be fully saved before saving the next
+           instance.  This is used in the extremely rare case that a
+           :class:`.MapperEvents` listener requires being called
+           in between individual row persistence operations.
+
+        :param column_prefix: A string which will be prepended
+           to the mapped attribute name when :class:`.Column`
+           objects are automatically assigned as attributes to the
+           mapped class.  Does not affect explicitly specified
+           column-based properties.
+
+           See the section :ref:`column_prefix` for an example.
+
+        :param concrete: If True, indicates this mapper should use concrete
+           table inheritance with its parent mapper.
+
+           See the section :ref:`concrete_inheritance` for an example.
+
+        :param confirm_deleted_rows: defaults to True; when a DELETE occurs
+          of one more rows based on specific primary keys, a warning is
+          emitted when the number of rows matched does not equal the number
+          of rows expected.  This parameter may be set to False to handle the
+          case where database ON DELETE CASCADE rules may be deleting some of
+          those rows automatically.  The warning may be changed to an
+          exception in a future release.
+
+          .. versionadded:: 0.9.4 - added
+             :paramref:`.mapper.confirm_deleted_rows` as well as conditional
+             matched row checking on delete.
+
+        :param eager_defaults: if True, the ORM will immediately fetch the
+          value of server-generated default values after an INSERT or UPDATE,
+          rather than leaving them as expired to be fetched on next access.
+          This can be used for event schemes where the server-generated values
+          are needed immediately before the flush completes.   By default,
+          this scheme will emit an individual ``SELECT`` statement per row
+          inserted or updated, which note can add significant performance
+          overhead.  However, if the
+          target database supports :term:`RETURNING`, the default values will
+          be returned inline with the INSERT or UPDATE statement, which can
+          greatly enhance performance for an application that needs frequent
+          access to just-generated server defaults.
+
+          .. versionchanged:: 0.9.0 The ``eager_defaults`` option can now
+             make use of :term:`RETURNING` for backends which support it.
+
+        :param exclude_properties: A list or set of string column names to
+          be excluded from mapping.
+
+          See :ref:`include_exclude_cols` for an example.
+
+        :param extension: A :class:`.MapperExtension` instance or
+           list of :class:`.MapperExtension` instances which will be applied
+           to all operations by this :class:`.Mapper`.  **Deprecated.**
+           Please see :class:`.MapperEvents`.
+
+        :param include_properties: An inclusive list or set of string column
+          names to map.
+
+          See :ref:`include_exclude_cols` for an example.
+
+        :param inherits: A mapped class or the corresponding :class:`.Mapper`
+          of one indicating a superclass to which this :class:`.Mapper`
+          should *inherit* from.   The mapped class here must be a subclass
+          of the other mapper's class.   When using Declarative, this argument
+          is passed automatically as a result of the natural class
+          hierarchy of the declared classes.
+
+          .. seealso::
+
+            :ref:`inheritance_toplevel`
+
+        :param inherit_condition: For joined table inheritance, a SQL
+           expression which will
+           define how the two tables are joined; defaults to a natural join
+           between the two tables.
+
+        :param inherit_foreign_keys: When ``inherit_condition`` is used and
+           the columns present are missing a :class:`.ForeignKey`
+           configuration, this parameter can be used to specify which columns
+           are "foreign".  In most cases can be left as ``None``.
+
+        :param legacy_is_orphan: Boolean, defaults to ``False``.
+          When ``True``, specifies that "legacy" orphan consideration
+          is to be applied to objects mapped by this mapper, which means
+          that a pending (that is, not persistent) object is auto-expunged
+          from an owning :class:`.Session` only when it is de-associated
+          from *all* parents that specify a ``delete-orphan`` cascade towards
+          this mapper.  The new default behavior is that the object is
+          auto-expunged when it is de-associated with *any* of its parents
+          that specify ``delete-orphan`` cascade.  This behavior is more
+          consistent with that of a persistent object, and allows behavior to
+          be consistent in more scenarios independently of whether or not an
+          orphanable object has been flushed yet or not.
+
+          See the change note and example at :ref:`legacy_is_orphan_addition`
+          for more detail on this change.
+
+          .. versionadded:: 0.8 - the consideration of a pending object as
+            an "orphan" has been modified to more closely match the
+            behavior as that of persistent objects, which is that the object
+            is expunged from the :class:`.Session` as soon as it is
+            de-associated from any of its orphan-enabled parents.  Previously,
+            the pending object would be expunged only if de-associated
+            from all of its orphan-enabled parents. The new flag
+            ``legacy_is_orphan`` is added to :func:`.orm.mapper` which
+            re-establishes the legacy behavior.
+
+        :param non_primary: Specify that this :class:`.Mapper` is in addition
+          to the "primary" mapper, that is, the one used for persistence.
+          The :class:`.Mapper` created here may be used for ad-hoc
+          mapping of the class to an alternate selectable, for loading
+          only.
+
+          :paramref:`.Mapper.non_primary` is not an often used option, but
+          is useful in some specific :func:`.relationship` cases.
+
+          .. seealso::
+
+              :ref:`relationship_non_primary_mapper`
+
+        :param order_by: A single :class:`.Column` or list of :class:`.Column`
+           objects for which selection operations should use as the default
+           ordering for entities.  By default mappers have no pre-defined
+           ordering.
+
+        :param passive_updates: Indicates UPDATE behavior of foreign key
+           columns when a primary key column changes on a joined-table
+           inheritance mapping.   Defaults to ``True``.
+
+           When True, it is assumed that ON UPDATE CASCADE is configured on
+           the foreign key in the database, and that the database will handle
+           propagation of an UPDATE from a source column to dependent columns
+           on joined-table rows.
+
+           When False, it is assumed that the database does not enforce
+           referential integrity and will not be issuing its own CASCADE
+           operation for an update.  The unit of work process will
+           emit an UPDATE statement for the dependent columns during a
+           primary key change.

+
+        :param polymorphic_on: Specifies the column, attribute, or
+          SQL expression used to determine the target class for an
+          incoming row, when inheriting classes are present.
+
+          This value is commonly a :class:`.Column` object that's
+          present in the mapped :class:`.Table`::
+
+            class Employee(Base):
+                __tablename__ = 'employee'
+
+                id = Column(Integer, primary_key=True)
+                discriminator = Column(String(50))
+
+                __mapper_args__ = {

+                    "polymorphic_identity":"employee"
+                }
+
+          It may also be specified
+          as a SQL expression, as in this example where we
+          use the :func:`.case` construct to provide a conditional
+          approach::
+
+            class Employee(Base):
+                __tablename__ = 'employee'
+
+                id = Column(Integer, primary_key=True)
+                discriminator = Column(String(50))
+
+                __mapper_args__ = {
+                    "polymorphic_on":case([
+                        (discriminator == "EN", "engineer"),
+                        (discriminator == "MA", "manager"),
+                    ], else_="employee"),
+                    "polymorphic_identity":"employee"
+                }
+
+          It may also refer to any attribute
+          configured with :func:`.column_property`, or to the
+          string name of one::
+
+                class Employee(Base):
+                    __tablename__ = 'employee'
+
+                    id = Column(Integer, primary_key=True)
+                    discriminator = Column(String(50))
+                    employee_type = column_property(
+                        case([
+                            (discriminator == "EN", "engineer"),
+                            (discriminator == "MA", "manager"),
+                        ], else_="employee")
+                    )
+
+                    __mapper_args__ = {
+                        "polymorphic_on":employee_type,
+                        "polymorphic_identity":"employee"
+                    }
+
+          .. versionchanged:: 0.7.4
+              ``polymorphic_on`` may be specified as a SQL expression,
+              or refer to any attribute configured with
+              :func:`.column_property`, or to the string name of one.
+
+          When setting ``polymorphic_on`` to reference an
+          attribute or expression that's not present in the
+          locally mapped :class:`.Table`, yet the value
+          of the discriminator should be persisted to the database,
+          the value of the
+          discriminator is not automatically set on new
+          instances; this must be handled by the user,
+          either through manual means or via event listeners.
+          A typical approach to establishing such a listener
+          looks like::
+
+                from sqlalchemy import event
+                from sqlalchemy.orm import object_mapper
+
+                @event.listens_for(Employee, "init", propagate=True)
+                def set_identity(instance, *arg, **kw):
+                    mapper = object_mapper(instance)
+                    instance.discriminator = mapper.polymorphic_identity
+
+          Where above, we assign the value of ``polymorphic_identity``
+          for the mapped class to the ``discriminator`` attribute,
+          thus persisting the value to the ``discriminator`` column
+          in the database.
+
+          .. seealso::
+
+            :ref:`inheritance_toplevel`
+
+        :param polymorphic_identity: Specifies the value which
+          identifies this particular class as returned by the
+          column expression referred to by the ``polymorphic_on``
+          setting.  As rows are received, the value corresponding
+          to the ``polymorphic_on`` column expression is compared
+          to this value, indicating which subclass should
+          be used for the newly reconstructed object.
+
+        :param properties: A dictionary mapping the string names of object
+           attributes to :class:`.MapperProperty` instances, which define the
+           persistence behavior of that attribute.  Note that :class:`.Column`
+           objects present in
+           the mapped :class:`.Table` are automatically placed into
+           ``ColumnProperty`` instances upon mapping, unless overridden.
+           When using Declarative, this argument is passed automatically,
+           based on all those :class:`.MapperProperty` instances declared
+           in the declared class body.
+
+        :param primary_key: A list of :class:`.Column` objects which define
+           the primary key to be used against this mapper's selectable unit.
+           This is normally simply the primary key of the ``local_table``, but
+           can be overridden here.
+
+        :param version_id_col: A :class:`.Column`
+           that will be used to keep a running version id of rows
+           in the table.  This is used to detect concurrent updates or
+           the presence of stale data in a flush.  The methodology is to
+           detect if an UPDATE statement does not match the last known
+           version id, a
+           :class:`~sqlalchemy.orm.exc.StaleDataError` exception is
+           thrown.
+           By default, the column must be of :class:`.Integer` type,
+           unless ``version_id_generator`` specifies an alternative version
+           generator.

+

+          be generated.  Defaults to ``None``, which indicates that
+          a simple integer counting scheme be employed.  To provide a custom
+          versioning scheme, provide a callable function of the form::
+
+              def generate_version(version):
+                  return next_version
+
+          Alternatively, server-side versioning functions such as triggers,
+          or programmatic versioning schemes outside of the version id
+          generator may be used, by specifying the value ``False``.

+            flush, that is, has any kind of "dirty" state within a flush.
+            Setting this parameter to ``False`` will have the effect of

+ORM session, whereas the ``Select`` construct interacts directly with the

+        and apply generatively, returning the newly resulting :class:`.Query`.
+
+        **Simple Relationship Joins**
+
+        Consider a mapping between two classes ``User`` and ``Address``,
+        with a relationship ``User.addresses`` representing a collection
+        of ``Address`` objects associated with each ``User``.   The most
+        common usage of :meth:`~.Query.join` is to create a JOIN along this
+        relationship, using the ``User.addresses`` attribute as an indicator
+        for how this should occur::
+
+            q = session.query(User).join(User.addresses)
+
+        Where above, the call to :meth:`~.Query.join` along ``User.addresses``
+        will result in SQL equivalent to::
+
+            SELECT user.* FROM user JOIN address ON user.id = address.user_id
+
+        In the above example we refer to ``User.addresses`` as passed to
+        :meth:`~.Query.join` as the *on clause*, that is, it indicates
+        how the "ON" portion of the JOIN should be constructed.  For a
+        single-entity query such as the one above (i.e. we start by selecting
+        only from ``User`` and nothing else), the relationship can also be
+        specified by its string name::
+
+            q = session.query(User).join("addresses")
+
+        :meth:`~.Query.join` can also accommodate multiple
+        "on clause" arguments to produce a chain of joins, such as below
+        where a join across four related entities is constructed::
+
+            q = session.query(User).join("orders", "items", "keywords")
+
+        The above would be shorthand for three separate calls to
+        :meth:`~.Query.join`, each using an explicit attribute to indicate
+        the source entity::
+
+            q = session.query(User).\\
+                    join(User.orders).\\
+                    join(Order.items).\\
+                    join(Item.keywords)
+
+        **Joins to a Target Entity or Selectable**
+
+        A second form of :meth:`~.Query.join` allows any mapped entity
+        or core selectable construct as a target.   In this usage,
+        :meth:`~.Query.join` will attempt
+        to create a JOIN along the natural foreign key relationship between
+        two entities::
+
+            q = session.query(User).join(Address)
+
+        The above calling form of :meth:`~.Query.join` will raise an error if
+        either there are no foreign keys between the two entities, or if
+        there are multiple foreign key linkages between them.   In the
+        above calling form, :meth:`~.Query.join` is called upon to
+        create the "on clause" automatically for us.  The target can
+        be any mapped entity or selectable, such as a :class:`.Table`::
+
+            q = session.query(User).join(addresses_table)
+
+        **Joins to a Target with an ON Clause**
+
+        The third calling form allows both the target entity as well
+        as the ON clause to be passed explicitly.   Suppose for
+        example we wanted to join to ``Address`` twice, using
+        an alias the second time.  We use :func:`~sqlalchemy.orm.aliased`
+        to create a distinct alias of ``Address``, and join
+        to it using the ``target, onclause`` form, so that the
+        alias can be specified explicitly as the target along with
+        the relationship to instruct how the ON clause should proceed::
+
+            a_alias = aliased(Address)
+
+            q = session.query(User).\\
+                    join(User.addresses).\\
+                    join(a_alias, User.addresses).\\
+                    filter(Address.email_address=='ed@foo.com').\\
+                    filter(a_alias.email_address=='ed@bar.com')
+
+        Where above, the generated SQL would be similar to::
+
+            SELECT user.* FROM user
+                JOIN address ON user.id = address.user_id
+                JOIN address AS address_1 ON user.id=address_1.user_id
+                WHERE address.email_address = :email_address_1
+                AND address_1.email_address = :email_address_2
+
+        The two-argument calling form of :meth:`~.Query.join`
+        also allows us to construct arbitrary joins with SQL-oriented
+        "on clause" expressions, not relying upon configured relationships
+        at all.  Any SQL expression can be passed as the ON clause
+        when using the two-argument form, which should refer to the target
+        entity in some way as well as an applicable source entity::
+
+            q = session.query(User).join(Address, User.id==Address.user_id)
+
+        .. versionchanged:: 0.7
+            In SQLAlchemy 0.6 and earlier, the two argument form of
+            :meth:`~.Query.join` requires the usage of a tuple:
+            ``query(User).join((Address, User.id==Address.user_id))``\ .
+            This calling form is accepted in 0.7 and further, though
+            is not necessary unless multiple join conditions are passed to
+            a single :meth:`~.Query.join` call, which itself is also not
+            generally necessary as it is now equivalent to multiple
+            calls (this wasn't always the case).
+
+        **Advanced Join Targeting and Adaption**
+
+        There is a lot of flexibility in what the "target" can be when using
+        :meth:`~.Query.join`.   As noted previously, it also accepts
+        :class:`.Table` constructs and other selectables such as
+        :func:`.alias` and :func:`.select` constructs, with either the one
+        or two-argument forms::
+
+            addresses_q = select([Address.user_id]).\\
+                        where(Address.email_address.endswith("@bar.com")).\\
+                        alias()
+
+            q = session.query(User).\\
+                        join(addresses_q, addresses_q.c.user_id==User.id)
+
+        :meth:`~.Query.join` also features the ability to *adapt* a
+        :meth:`~sqlalchemy.orm.relationship` -driven ON clause to the target
+        selectable. Below we construct a JOIN from ``User`` to a subquery
+        against ``Address``, allowing the relationship denoted by
+        ``User.addresses`` to *adapt* itself to the altered target::
+
+            address_subq = session.query(Address).\\
+                            filter(Address.email_address == 'ed@foo.com').\\
+                            subquery()
+
+            q = session.query(User).join(address_subq, User.addresses)
+
+        Producing SQL similar to::
+
+            SELECT user.* FROM user
+                JOIN (
+                    SELECT address.id AS id,
+                            address.user_id AS user_id,
+                            address.email_address AS email_address
+                    FROM address
+                    WHERE address.email_address = :email_address_1
+                ) AS anon_1 ON user.id = anon_1.user_id
+
+        The above form allows one to fall back onto an explicit ON
+        clause at any time::
+
+            q = session.query(User).\\
+                    join(address_subq, User.id==address_subq.c.user_id)
+
+        **Controlling what to Join From**
+
+        While :meth:`~.Query.join` exclusively deals with the "right"
+        side of the JOIN, we can also control the "left" side, in those
+        cases where it's needed, using :meth:`~.Query.select_from`.
+        Below we construct a query against ``Address`` but can still
+        make usage of ``User.addresses`` as our ON clause by instructing
+        the :class:`.Query` to select first from the ``User``
+        entity::
+
+            q = session.query(Address).select_from(User).\\
+                            join(User.addresses).\\
+                            filter(User.name == 'ed')
+
+        Which will produce SQL similar to::
+
+            SELECT address.* FROM user
+                JOIN address ON user.id=address.user_id
+                WHERE user.name = :name_1
+
+        **Constructing Aliases Anonymously**
+
+        :meth:`~.Query.join` can construct anonymous aliases
+        using the ``aliased=True`` flag.  This feature is useful
+        when a query is being joined algorithmically, such as
+        when querying self-referentially to an arbitrary depth::
+
+            q = session.query(Node).\\
+                    join("children", "children", aliased=True)
+
+        When ``aliased=True`` is used, the actual "alias" construct
+        is not explicitly available.  To work with it, methods such as
+        :meth:`.Query.filter` will adapt the incoming entity to
+        the last join point::
+
+            q = session.query(Node).\\
+                    join("children", "children", aliased=True).\\
+                    filter(Node.name == 'grandchild 1')
+
+        When using automatic aliasing, the ``from_joinpoint=True``
+        argument can allow a multi-node join to be broken into
+        multiple calls to :meth:`~.Query.join`, so that
+        each path along the way can be further filtered::
+
+            q = session.query(Node).\\
+                    join("children", aliased=True).\\
+                    filter(Node.name='child 1').\\
+                    join("children", aliased=True, from_joinpoint=True).\\
+                    filter(Node.name == 'grandchild 1')
+
+        The filtering aliases above can then be reset back to the
+        original ``Node`` entity using :meth:`~.Query.reset_joinpoint`::
+
+            q = session.query(Node).\\
+                    join("children", "children", aliased=True).\\
+                    filter(Node.name == 'grandchild 1').\\
+                    reset_joinpoint().\\
+                    filter(Node.name == 'parent 1)
+
+        For an example of ``aliased=True``, see the distribution
+        example :ref:`examples_xmlpersistence` which illustrates
+        an XPath-like query system using algorithmic joins.
+
+        :param \*props: A collection of one or more join conditions,
+         each consisting of a relationship-bound attribute or string
+         relationship name representing an "on clause", or a single
+         target entity, or a tuple in the form of ``(target, onclause)``.
+         A special two-argument calling form of the form ``target, onclause``
+         is also accepted.
+        :param aliased=False: If True, indicate that the JOIN target should be
+         anonymously aliased.  Subsequent calls to :meth:`~.Query.filter`
+         and similar will adapt the incoming criterion to the target
+         alias, until :meth:`~.Query.reset_joinpoint` is called.
+        :param from_joinpoint=False: When using ``aliased=True``, a setting
+         of True here will cause the join to be from the most recent
+         joined target, rather than starting back from the original
+         FROM clauses of the query.

+
+        This method is similar to the :meth:`.Query.select_from`
+        method, in that it sets the FROM clause of the query.  However,
+        where :meth:`.Query.select_from` only affects what is placed
+        in the FROM, this method also applies the given selectable
+        to replace the FROM which the selected entities would normally
+        select from.
+
+        The given ``from_obj`` must be an instance of a :class:`.FromClause`,
+        e.g. a :func:`.select` or :class:`.Alias` construct.
+
+        An example would be a :class:`.Query` that selects ``User`` entities,
+        but uses :meth:`.Query.select_entity_from` to have the entities
+        selected from a :func:`.select` construct instead of the
+        base ``user`` table::
+
+            select_stmt = select([User]).where(User.id == 7)
+
+            q = session.query(User).\\
+                    select_entity_from(select_stmt).\\
+                    filter(User.name == 'ed')
+
+        The query generated will select ``User`` entities directly
+        from the given :func:`.select` construct, and will be::
+
+            SELECT anon_1.id AS anon_1_id, anon_1.name AS anon_1_name
+            FROM (SELECT "user".id AS id, "user".name AS name
+            FROM "user"
+            WHERE "user".id = :id_1) AS anon_1
+            WHERE anon_1.name = :name_1
+
+        Notice above that even the WHERE criterion was "adapted" such that
+        the ``anon_1`` subquery effectively replaces all references to the
+        ``user`` table, except for the one that it refers to internally.
+
+        Compare this to :meth:`.Query.select_from`, which as of
+        version 0.9, does not affect existing entities.  The
+        statement below::
+
+            q = session.query(User).\\
+                    select_from(select_stmt).\\
+                    filter(User.name == 'ed')
+
+        Produces SQL where both the ``user`` table as well as the
+        ``select_stmt`` construct are present as separate elements
+        in the FROM clause.  No "adaptation" of the ``user`` table
+        is applied::
+
+            SELECT "user".id AS user_id, "user".name AS user_name
+            FROM "user", (SELECT "user".id AS id, "user".name AS name
+            FROM "user"
+            WHERE "user".id = :id_1) AS anon_1
+            WHERE "user".name = :name_1
+
+        :meth:`.Query.select_entity_from` maintains an older
+        behavior of :meth:`.Query.select_from`.  In modern usage,
+        similar results can also be achieved using :func:`.aliased`::
+
+            select_stmt = select([User]).where(User.id == 7)
+            user_from_select = aliased(User, select_stmt.alias())
+
+            q = session.query(user_from_select)
+
+        :param from_obj: a :class:`.FromClause` object that will replace
+         the FROM clause of this :class:`.Query`.

+          Care must be taken in any multiple-table update to explicitly
+          include the joining condition between those tables, even in mappings
+          where this is normally automatic.
+          E.g. if a class ``Engineer`` subclasses ``Employee``, an UPDATE of
+          the ``Engineer`` local table using criteria against the ``Employee``
+          local table might look like::
+
+                session.query(Engineer).\\
+                    filter(Engineer.id == Employee.id).\\
+                    filter(Employee.name == 'dilbert').\\
+                    update({"engineer_type": "programmer"})

+
+        This corresponds to a parent-child or associative table relationship.
+        The constructed class is an instance of
+        :class:`.RelationshipProperty`.
+
+        A typical :func:`.relationship`, used in a classical mapping::
+
+           mapper(Parent, properties={
+             'children': relationship(Child)
+           })
+
+        Some arguments accepted by :func:`.relationship` optionally accept a
+        callable function, which when called produces the desired value.
+        The callable is invoked by the parent :class:`.Mapper` at "mapper
+        initialization" time, which happens only when mappers are first used,
+        and is assumed to be after all mappings have been constructed.  This
+        can be used to resolve order-of-declaration and other dependency
+        issues, such as if ``Child`` is declared below ``Parent`` in the same
+        file::
+
+            mapper(Parent, properties={
+                "children":relationship(lambda: Child,
+                                    order_by=lambda: Child.id)
+            })
+
+        When using the :ref:`declarative_toplevel` extension, the Declarative
+        initializer allows string arguments to be passed to
+        :func:`.relationship`.  These string arguments are converted into
+        callables that evaluate the string as Python code, using the
+        Declarative class-registry as a namespace.  This allows the lookup of
+        related classes to be automatic via their string name, and removes the
+        need to import related classes at all into the local module space::
+
+            from sqlalchemy.ext.declarative import declarative_base
+
+            Base = declarative_base()
+
+            class Parent(Base):

+                id = Column(Integer, primary_key=True)

+
+          :paramref:`~.relationship.argument` may also be passed as a callable

+          In less common circumstances, the argument may also be specified
+          as an :class:`.Alias` construct, or even a :class:`.Join` construct.
+
+          :paramref:`~.relationship.secondary` may
+          also be passed as a callable function which is evaluated at
+          mapper initialization time.  When using Declarative, it may also

+          present in the :class:`.MetaData` collection associated with the
+          parent-mapped :class:`.Table`.
+
+          The :paramref:`~.relationship.secondary` keyword argument is
+          typically applied in the case where the intermediary :class:`.Table`
+          is not otherwise exprssed in any direct class mapping. If the
+          "secondary" table is also explicitly mapped elsewhere (e.g. as in

+          :paramref:`~.relationship.viewonly` flag so that this

+          may conflict with those of the association object pattern.

+          When ``True``, indicates that the "previous" value for a
+          many-to-one reference should be loaded when replaced, if
+          not already loaded. Normally, history tracking logic for
+          simple many-to-ones only needs to be aware of the "new"

+          This defaults to ``False``, which means the default cascade
+          should be used - this default cascade is ``"save-update, merge"``.
+
+          The available cascades are ``save-update``, ``merge``,
+          ``expunge``, ``delete``, ``delete-orphan``, and ``refresh-expire``.
+          An additional option, ``all`` indicates shorthand for
+          ``"save-update, merge, refresh-expire,
+          expunge, delete"``, and is often used as in ``"all, delete-orphan"``
+          to indicate that related objects should follow along with the

+          When set to ``False``, the attribute managed by this relationship

+          the DISTINCT keyword will be applied in those cases when the target
+          columns do not comprise the full primary key of the target table.
+          When set to ``True``, the DISTINCT keyword is applied to the
+          innermost SELECT unconditionally.
+
+          It may be desirable to set this flag to False when the DISTINCT is
+          reducing performance of the innermost subquery beyond that of what
+          duplicate innermost rows may be causing.
+
+          .. versionadded:: 0.8.3 -
+             :paramref:`~.relationship.distinct_target_key` allows the

+
+        :param foreign_keys:
+
+          a list of columns which are to be used as "foreign key"
+          columns, or columns which refer to the value in a remote
+          column, within the context of this :func:`.relationship`
+          object's :paramref:`~.relationship.primaryjoin` condition.
+          That is, if the :paramref:`~.relationship.primaryjoin`
+          condition of this :func:`.relationship` is ``a.id ==
+          b.a_id``, and the values in ``b.a_id`` are required to be
+          present in ``a.id``, then the "foreign key" column of this
+          :func:`.relationship` is ``b.a_id``.
+
+          In normal cases, the :paramref:`~.relationship.foreign_keys`
+          parameter is **not required.** :func:`.relationship` will
+          automatically determine which columns in the
+          :paramref:`~.relationship.primaryjoin` conditition are to be
+          considered "foreign key" columns based on those
+          :class:`.Column` objects that specify :class:`.ForeignKey`,
+          or are otherwise listed as referencing columns in a
+          :class:`.ForeignKeyConstraint` construct.
+          :paramref:`~.relationship.foreign_keys` is only needed when:
+
+            1. There is more than one way to construct a join from the local
+               table to the remote table, as there are multiple foreign key
+               references present.  Setting ``foreign_keys`` will limit the
+               :func:`.relationship` to consider just those columns specified
+               here as "foreign".
+
+               .. versionchanged:: 0.8
+                    A multiple-foreign key join ambiguity can be resolved by
+                    setting the :paramref:`~.relationship.foreign_keys`
+                    parameter alone, without the need to explicitly set
+                    :paramref:`~.relationship.primaryjoin` as well.
+
+            2. The :class:`.Table` being mapped does not actually have
+               :class:`.ForeignKey` or :class:`.ForeignKeyConstraint`
+               constructs present, often because the table
+               was reflected from a database that does not support foreign key
+               reflection (MySQL MyISAM).
+
+            3. The :paramref:`~.relationship.primaryjoin` argument is used to
+               construct a non-standard join condition, which makes use of
+               columns or expressions that do not normally refer to their
+               "parent" column, such as a join condition expressed by a
+               complex comparison using a SQL function.
+
+          The :func:`.relationship` construct will raise informative
+          error messages that suggest the use of the
+          :paramref:`~.relationship.foreign_keys` parameter when
+          presented with an ambiguous condition.   In typical cases,
+          if :func:`.relationship` doesn't raise any exceptions, the
+          :paramref:`~.relationship.foreign_keys` parameter is usually
+          not needed.
+
+          :paramref:`~.relationship.foreign_keys` may also be passed as a
+          callable function which is evaluated at mapper initialization time,
+          and may be passed as a Python-evaluable string when using
+          Declarative.

+              The :func:`.foreign` annotation can also be applied
+              directly to the :paramref:`~.relationship.primaryjoin`
+              expression, which is an alternate, more specific system of
+              describing which columns in a particular
+              :paramref:`~.relationship.primaryjoin` should be considered
+              "foreign".

+
+        :param innerjoin=False:
+          when ``True``, joined eager loads will use an inner join to join
+          against related tables instead of an outer join.  The purpose
+          of this option is generally one of performance, as inner joins
+          generally perform better than outer joins.
+
+          This flag can be set to ``True`` when the relationship references an
+          object via many-to-one using local foreign keys that are not
+          nullable, or when the reference is one-to-one or a collection that
+          is guaranteed to have one or at least one entry.
+
+          If the joined-eager load is chained onto an existing LEFT OUTER
+          JOIN, ``innerjoin=True`` will be bypassed and the join will continue
+          to chain as LEFT OUTER JOIN so that the results don't change.  As an
+          alternative, specify the value ``"nested"``.  This will instead nest
+          the join on the right side, e.g. using the form "a LEFT OUTER JOIN
+          (b JOIN c)".

+          relationship.  The number counts how many times the same Mapper
+          shall be present in the loading condition along a particular join
+          branch.  When left at its default of ``None``, eager loaders
+          will stop chaining when they encounter a the same target mapper
+          which is already higher up in the chain.  This option applies

+
+        :param lazy='select': specifies
+          how the related items should be loaded.  Default value is
+          ``select``.  Values include:
+
+          * ``select`` - items should be loaded lazily when the property is
+            first accessed, using a separate SELECT statement, or identity map
+            fetch for simple many-to-one references.
+
+          * ``immediate`` - items should be loaded as the parents are loaded,
+            using a separate SELECT statement, or identity map fetch for
+            simple many-to-one references.
+
+          * ``joined`` - items should be loaded "eagerly" in the same query as
+            that of the parent, using a JOIN or LEFT OUTER JOIN.  Whether
+            the join is "outer" or not is determined by the
+            :paramref:`~.relationship.innerjoin` parameter.
+
+          * ``subquery`` - items should be loaded "eagerly" as the parents are
+            loaded, using one additional SQL statement, which issues a JOIN to
+            a subquery of the original statement, for each collection
+            requested.
+
+          * ``noload`` - no loading should occur at any time.  This is to
+            support "write-only" attributes, or attributes which are
+            populated in some manner specific to the application.
+
+          * ``dynamic`` - the attribute will return a pre-configured
+            :class:`.Query` object for all read
+            operations, onto which further filtering operations can be
+            applied before iterating the results.  See

+          when autoflush is disabled, or for a transient object that has been
+          "attached" to a :class:`.Session` but is not part of its pending
+          collection.
+
+          The :paramref:`~.relationship.load_on_pending` flag does not improve
+          behavior when the ORM is used normally - object references should be
+          constructed at the object level, not at the foreign key level, so
+          that they are present in an ordinary way before a flush proceeds.
+          This flag is not not intended for general use.
+
+          .. seealso::
+
+              :meth:`.Session.enable_relationship_loading` - this method
+              establishes "load on pending" behavior for the whole object, and
+              also allows loading on objects that remain transient or
+              detached.
+
+        :param order_by:
+          indicates the ordering that should be applied when loading these
+          items.  :paramref:`~.relationship.order_by` is expected to refer to
+          one of the :class:`.Column` objects to which the target class is
+          mapped, or the attribute itself bound to the target class which
+          refers to the column.
+
+          :paramref:`~.relationship.order_by` may also be passed as a callable
+          function which is evaluated at mapper initialization time, and may
+          be passed as a Python-evaluable string when using Declarative.
+
+        :param passive_deletes=False:
+           Indicates loading behavior during delete operations.
+
+           A value of True indicates that unloaded child items should not
+           be loaded during a delete operation on the parent.  Normally,
+           when a parent item is deleted, all child items are loaded so
+           that they can either be marked as deleted, or have their
+           foreign key to the parent set to NULL.  Marking this flag as
+           True usually implies an ON DELETE <CASCADE|SET NULL> rule is in
+           place which will handle updating/deleting child rows on the
+           database side.
+
+           Additionally, setting the flag to the string value 'all' will
+           disable the "nulling out" of the child foreign keys, when there
+           is no delete or delete-orphan cascade enabled.  This is
+           typically used when a triggering or error raise scenario is in
+           place on the database side.  Note that the foreign key
+           attributes on in-session child objects will not be changed
+           after a flush occurs so this is a very special use-case
+           setting.
+
+           .. seealso::
+
+                :ref:`passive_deletes` - Introductory documentation
+                and examples.
+
+        :param passive_updates=True:
+          Indicates loading and INSERT/UPDATE/DELETE behavior when the
+          source of a foreign key value changes (i.e. an "on update"
+          cascade), which are typically the primary key columns of the
+          source row.
+
+          When True, it is assumed that ON UPDATE CASCADE is configured on
+          the foreign key in the database, and that the database will
+          handle propagation of an UPDATE from a source column to
+          dependent rows.  Note that with databases which enforce
+          referential integrity (i.e. PostgreSQL, MySQL with InnoDB tables),
+          ON UPDATE CASCADE is required for this operation.  The
+          relationship() will update the value of the attribute on related
+          items which are locally present in the session during a flush.
+
+          When False, it is assumed that the database does not enforce
+          referential integrity and will not be issuing its own CASCADE
+          operation for an update.  The relationship() will issue the
+          appropriate UPDATE statements to the database in response to the
+          change of a referenced key, and items locally present in the
+          session during a flush will also be refreshed.
+
+          This flag should probably be set to False if primary key changes
+          are expected and the database in use doesn't support CASCADE
+          (i.e. SQLite, MySQL MyISAM tables).
+
+          .. seealso::
+
+              :ref:`passive_updates` - Introductory documentation and
+              examples.
+
+              :paramref:`.mapper.passive_updates` - a similar flag which
+              takes effect for joined-table inheritance mappings.
+
+        :param post_update:
+          this indicates that the relationship should be handled by a
+          second UPDATE statement after an INSERT or before a
+          DELETE. Currently, it also will issue an UPDATE after the
+          instance was UPDATEd as well, although this technically should
+          be improved. This flag is used to handle saving bi-directional
+          dependencies between two individual rows (i.e. each row
+          references the other), where it would otherwise be impossible to
+          INSERT or DELETE both rows fully since one row exists before the
+          other. Use this flag when a particular mapping arrangement will
+          incur two rows that are dependent on each other, such as a table
+          that has a one-to-many relationship to a set of child rows, and
+          also has a column that references a single child row within that
+          list (i.e. both tables contain a foreign key to each other). If
+          a flush operation returns an error that a "cyclical
+          dependency" was detected, this is a cue that you might want to
+          use :paramref:`~.relationship.post_update` to "break" the cycle.

+          automatically by :func:`.relationship` at mapper configuration
+          time, based on the type and direction
+          of the relationship - one to many forms a list, many to one
+          forms a scalar, many to many is a list. If a scalar is desired
+          where normally a list would be present, such as a bi-directional

+
+    """A :class:`.Session`-level transaction.
+
+    :class:`.SessionTransaction` is a mostly behind-the-scenes object
+    not normally referenced directly by application code.   It coordinates
+    among multiple :class:`.Connection` objects, maintaining a database
+    transaction for each one individually, committing or rolling them
+    back all at once.   It also provides optional two-phase commit behavior
+    which can augment this coordination operation.
+
+    The :attr:`.Session.transaction` attribute of :class:`.Session`
+    refers to the current :class:`.SessionTransaction` object in use, if any.
+
+
+    A :class:`.SessionTransaction` is associated with a :class:`.Session`
+    in its default mode of ``autocommit=False`` immediately, associated
+    with no database connections.  As the :class:`.Session` is called upon
+    to emit SQL on behalf of various :class:`.Engine` or :class:`.Connection`
+    objects, a corresponding :class:`.Connection` and associated
+    :class:`.Transaction` is added to a collection within the
+    :class:`.SessionTransaction` object, becoming one of the
+    connection/transaction pairs maintained by the
+    :class:`.SessionTransaction`.
+
+    The lifespan of the :class:`.SessionTransaction` ends when the
+    :meth:`.Session.commit`, :meth:`.Session.rollback` or
+    :meth:`.Session.close` methods are called.  At this point, the
+    :class:`.SessionTransaction` removes its association with its parent
+    :class:`.Session`.   A :class:`.Session` that is in ``autocommit=False``
+    mode will create a new :class:`.SessionTransaction` to replace it
+    immediately, whereas a :class:`.Session` that's in ``autocommit=True``
+    mode will remain without a :class:`.SessionTransaction` until the
+    :meth:`.Session.begin` method is called.
+
+    Another detail of :class:`.SessionTransaction` behavior is that it is
+    capable of "nesting".  This means that the :meth:`.Session.begin` method
+    can be called while an existing :class:`.SessionTransaction` is already
+    present, producing a new :class:`.SessionTransaction` that temporarily
+    replaces the parent :class:`.SessionTransaction`.   When a
+    :class:`.SessionTransaction` is produced as nested, it assigns itself to
+    the :attr:`.Session.transaction` attribute.  When it is ended via
+    :meth:`.Session.commit` or :meth:`.Session.rollback`, it restores its
+    parent :class:`.SessionTransaction` back onto the
+    :attr:`.Session.transaction` attribute.  The behavior is effectively a
+    stack, where :attr:`.Session.transaction` refers to the current head of
+    the stack.
+
+    The purpose of this stack is to allow nesting of
+    :meth:`.Session.rollback` or :meth:`.Session.commit` calls in context
+    with various flavors of :meth:`.Session.begin`. This nesting behavior
+    applies to when :meth:`.Session.begin_nested` is used to emit a
+    SAVEPOINT transaction, and is also used to produce a so-called
+    "subtransaction" which allows a block of code to use a
+    begin/rollback/commit sequence regardless of whether or not its enclosing
+    code block has begun a transaction.  The :meth:`.flush` method, whether
+    called explicitly or via autoflush, is the primary consumer of the
+    "subtransaction" feature, in that it wishes to guarantee that it works
+    within in a transaction block regardless of whether or not the
+    :class:`.Session` is in transactional mode when the method is called.

+          and will acquire connections from the engine on an as-needed basis,
+          returning them immediately after their use. Flushes will begin and
+          commit (or possibly rollback) their own transaction if no
+          transaction is present. When using this mode, the
+          :meth:`.Session.begin` method is used to explicitly start
+          transactions.
+
+          .. seealso::
+
+            :ref:`session_autocommit`
+
+        :param autoflush: When ``True``, all query operations will issue a
+           :meth:`~.Session.flush` call to this ``Session`` before proceeding.
+           This is a convenience feature so that :meth:`~.Session.flush` need
+           not be called repeatedly in order for database queries to retrieve
+           results. It's typical that ``autoflush`` is used in conjunction with
+           ``autocommit=False``. In this scenario, explicit calls to
+           :meth:`~.Session.flush` are rarely needed; you usually only need to
+           call :meth:`~.Session.commit` (which flushes) to finalize changes.
+
+        :param bind: An optional :class:`.Engine` or :class:`.Connection` to
+           which this ``Session`` should be bound. When specified, all SQL
+           operations performed by this session will execute via this
+           connectable.
+
+        :param binds: An optional dictionary which contains more granular
+           "bind" information than the ``bind`` parameter provides. This
+           dictionary can map individual :class`.Table`
+           instances as well as :class:`~.Mapper` instances to individual
+           :class:`.Engine` or :class:`.Connection` objects. Operations which
+           proceed relative to a particular :class:`.Mapper` will consult this
+           dictionary for the direct :class:`.Mapper` instance as
+           well as the mapper's ``mapped_table`` attribute in order to locate a
+           connectable to use. The full resolution is described in the
+           :meth:`.Session.get_bind`.
+           Usage looks like::
+
+            Session = sessionmaker(binds={
+                SomeMappedClass: create_engine('postgresql://engine1'),
+                somemapper: create_engine('postgresql://engine2'),
+                some_table: create_engine('postgresql://engine3'),
+                })
+
+          Also see the :meth:`.Session.bind_mapper`
+          and :meth:`.Session.bind_table` methods.
+
+        :param \class_: Specify an alternate class other than
+           ``sqlalchemy.orm.session.Session`` which should be used by the
+           returned class. This is the only argument that is local to the
+           :class:`.sessionmaker` function, and is not sent directly to the
+           constructor for ``Session``.
+
+        :param _enable_transaction_accounting:  Defaults to ``True``.  A
+           legacy-only flag which when ``False`` disables *all* 0.5-style
+           object accounting on transaction boundaries, including auto-expiry
+           of instances on rollback and commit, maintenance of the "new" and
+           "deleted" lists upon rollback, and autoflush of pending changes
+           upon :meth:`~.Session.begin`, all of which are interdependent.
+
+        :param expire_on_commit:  Defaults to ``True``. When ``True``, all
+           instances will be fully expired after each :meth:`~.commit`,
+           so that all attribute/object access subsequent to a completed
+           transaction will load from the most recent database state.
+
+        :param extension: An optional
+           :class:`~.SessionExtension` instance, or a list
+           of such instances, which will receive pre- and post- commit and
+           flush events, as well as a post-rollback event. **Deprecated.**
+           Please see :class:`.SessionEvents`.
+
+        :param info: optional dictionary of arbitrary data to be associated
+           with this :class:`.Session`.  Is available via the
+           :attr:`.Session.info` attribute.  Note the dictionary is copied at
+           construction time so that modifications to the per-
+           :class:`.Session` dictionary will be local to that
+           :class:`.Session`.
+
+           .. versionadded:: 0.9.0
+
+        :param query_cls:  Class which should be used to create new Query
+           objects, as returned by the :meth:`~.Session.query` method. Defaults
+           to :class:`.Query`.
+
+        :param twophase:  When ``True``, all transactions will be started as
+            a "two phase" transaction, i.e. using the "two phase" semantics
+            of the database in use along with an XID.  During a
+            :meth:`~.commit`, after :meth:`~.flush` has been issued for all
+            attached databases, the :meth:`~.TwoPhaseTransaction.prepare`
+            method on each database's :class:`.TwoPhaseTransaction` will be
+            called. This allows each database to roll back the entire
+            transaction, before each transaction is committed.
+
+        :param weak_identity_map:  Defaults to ``True`` - when set to

+           :class:`.Session` is closed.  **Deprecated** - this option

+        dictionary, or a list of dictionaries, determines whether the DBAPI
+        cursor's ``execute()`` or ``executemany()`` is used to execute the
+        statement.   An INSERT construct may be invoked for a single row::
+
+            result = session.execute(
+                users.insert(), {"id": 7, "name": "somename"})

+                                ])
+
+        The statement is executed within the current transactional context of
+        this :class:`.Session`.   The :class:`.Connection` which is used
+        to execute the statement can also be acquired directly by
+        calling the :meth:`.Session.connection` method.  Both methods use
+        a rule-based resolution scheme in order to determine the
+        :class:`.Connection`, which in the average case is derived directly
+        from the "bind" of the :class:`.Session` itself, and in other cases
+        can be based on the :func:`.mapper`
+        and :class:`.Table` objects passed to the method; see the
+        documentation for :meth:`.Session.get_bind` for a full description of
+        this scheme.
+
+        The :meth:`.Session.execute` method does *not* invoke autoflush.
+
+        The :class:`.ResultProxy` returned by the :meth:`.Session.execute`
+        method is returned with the "close_with_result" flag set to true;
+        the significance of this flag is that if this :class:`.Session` is
+        autocommitting and does not have a transaction-dedicated
+        :class:`.Connection` available, a temporary :class:`.Connection` is
+        established for the statement execution, which is closed (meaning,
+        returned to the connection pool) when the :class:`.ResultProxy` has
+        consumed all available data. This applies *only* when the
+        :class:`.Session` is configured with autocommit=True and no

+         any existing related objects or collections that might not
+         be loaded.  The resulting objects from ``load=False`` are always
+         produced as "clean", so it is only appropriate that the given objects

+
+            :meth:`.enable_relationship_loading` exists to serve special
+            use cases and is not recommended for general use.
+
+        Accesses of attributes mapped with :func:`.relationship`
+        will attempt to load a value from the database using this
+        :class:`.Session` as the source of connectivity.  The values
+        will be loaded based on foreign key values present on this
+        object - it follows that this functionality
+        generally only works for many-to-one-relationships.
+
+        The object will be attached to this session, but will
+        **not** participate in any persistence operations; its state
+        for almost all purposes will remain either "transient" or
+        "detached", except for the case of relationship loading.
+
+        Also note that backrefs will often not work as expected.
+        Altering a relationship-bound attribute on the target object
+        may not fire off a backref event, if the effective value
+        is what was already loaded from a foreign-key-holding value.
+
+        The :meth:`.Session.enable_relationship_loading` method is
+        similar to the ``load_on_pending`` flag on :func:`.relationship`.
+        Unlike that flag, :meth:`.Session.enable_relationship_loading` allows
+        an object to remain transient while still being able to load
+        related items.
+
+        To make a transient object associated with a :class:`.Session`
+        via :meth:`.Session.enable_relationship_loading` pending, add
+        it to the :class:`.Session` using :meth:`.Session.add` normally.
+
+        :meth:`.Session.enable_relationship_loading` does not improve
+        behavior when the ORM is used normally - object references should be
+        constructed at the object level, not at the foreign key level, so
+        that they are present in an ordinary way before flush()

+
+        It is in effect a more expensive and accurate
+        version of checking for the given instance in the
+        :attr:`.Session.dirty` collection; a full test for
+        each attribute's net "dirty" status is performed.

+
+            return session.is_modified(someobject)
+
+        .. versionchanged:: 0.8
+            When using SQLAlchemy 0.7 and earlier, the ``passive``
+            flag should **always** be explicitly set to ``True``,
+            else SQL loads/autoflushes may proceed which can affect
+            the modified state itself:
+            ``session.is_modified(someobject, passive=True)``\ .
+            In 0.8 and above, the behavior is corrected and
+            this flag is ignored.
+
+        A few caveats to this method apply:
+
+        * Instances present in the :attr:`.Session.dirty` collection may
+          report ``False`` when tested with this method.  This is because
+          the object may have received change events via attribute mutation,
+          thus placing it in :attr:`.Session.dirty`, but ultimately the state
+          is the same as that loaded from the database, resulting in no net
+          change here.
+        * Scalar attributes may not have recorded the previously set
+          value when a new value was applied, if the attribute was not loaded,
+          or was expired, at the time the new value was received - in these
+          cases, the attribute is assumed to have a change, even if there is
+          ultimately no net change against its database value. SQLAlchemy in
+          most cases does not need the "old" value when a set event occurs, so
+          it skips the expense of a SQL call if the old value isn't present,
+          based on the assumption that an UPDATE of the scalar value is
+          usually needed, and in those few cases where it isn't, is less
+          expensive on average than issuing a defensive SELECT.
+
+          The "old" value is fetched unconditionally upon set only if the
+          attribute container has the ``active_history`` flag set to ``True``.
+          This flag is set typically for primary key attributes and scalar
+          object references that are not a simple many-to-one.  To set this
+          flag for any arbitrary mapped column, use the ``active_history``
+          argument with :func:`.column_property`.
+
+        :param instance: mapped instance to be tested for pending changes.
+        :param include_collections: Indicates if multivalued collections
+         should be included in the operation.  Setting this to ``False`` is a
+         way to detect only local-column based properties (i.e. scalar columns
+         or many-to-one foreign keys) that would result in an UPDATE for this
+         instance upon flush.
+        :param passive:

+
+        The :class:`.Session` in its default mode of ``autocommit=False``
+        is essentially always in "transaction mode", in that a
+        :class:`.SessionTransaction` is associated with it as soon as
+        it is instantiated.  This :class:`.SessionTransaction` is immediately
+        replaced with a new one as soon as it is ended, due to a rollback,
+        commit, or close operation.
+
+        "Transaction mode" does *not* indicate whether
+        or not actual database connection resources are in use;  the
+        :class:`.SessionTransaction` object coordinates among zero or more
+        actual database transactions, and starts out with none, accumulating
+        individual DBAPI connections as different data sources are used
+        within its scope.   The best way to track when a particular
+        :class:`.Session` has actually begun to use DBAPI resources is to
+        implement a listener using the :meth:`.SessionEvents.after_begin`
+        method, which will deliver both the :class:`.Session` as well as the
+        target :class:`.Connection` to a user-defined event listener.
+
+        The "partial rollback" state refers to when an "inner" transaction,
+        typically used during a flush, encounters an error and emits a
+        rollback of the DBAPI connection.  At this point, the
+        :class:`.Session` is in "partial rollback" and awaits for the user to
+        call :meth:`.Session.rollback`, in order to close out the
+        transaction stack.  It is in this "partial rollback" period that the
+        :attr:`.is_active` flag returns False.  After the call to
+        :meth:`.Session.rollback`, the :class:`.SessionTransaction` is
+        replaced with a new one and :attr:`.is_active` returns ``True`` again.
+
+        When a :class:`.Session` is used in ``autocommit=True`` mode, the
+        :class:`.SessionTransaction` is only instantiated within the scope
+        of a flush call, or when :meth:`.Session.begin` is called.  So
+        :attr:`.is_active` will always be ``False`` outside of a flush or
+        :meth:`.Session.begin` block in this mode, and will be ``True``
+        within the :meth:`.Session.begin` block as long as it doesn't enter
+        "partial rollback" state.
+
+        From all the above, it follows that the only purpose to this flag is
+        for application frameworks that wish to detect is a "rollback" is
+        necessary within a generic error handling routine, for
+        :class:`.Session` objects that would otherwise be in
+        "partial rollback" mode.  In a typical integration case, this is also
+        not necessary as it is standard practice to emit
+        :meth:`.Session.rollback` unconditionally within the outermost
+        exception catch.
+
+        To track the transactional state of a :class:`.Session` fully,
+        use event listeners, primarily the :meth:`.SessionEvents.after_begin`,
+        :meth:`.SessionEvents.after_commit`,
+        :meth:`.SessionEvents.after_rollback` and related events.

+class Load(Generative, MapperOption):
+    """Represents loader options which modify the state of a
+    :class:`.Query` in order to affect how various mapped attributes are
+    loaded.
+
+    .. versionadded:: 0.9.0 The :meth:`.Load` system is a new foundation for
+       the existing system of loader options, including options such as
+       :func:`.orm.joinedload`, :func:`.orm.defer`, and others.   In
+       particular, it introduces a new method-chained system that replaces the
+       need for dot-separated paths as well as "_all()" options such as
+       :func:`.orm.joinedload_all`.
+
+    A :class:`.Load` object can be used directly or indirectly.  To use one
+    directly, instantiate given the parent class.  This style of usage is
+    useful when dealing with a :class:`.Query` that has multiple entities,
+    or when producing a loader option that can be applied generically to
+    any style of query::
+
+        myopt = Load(MyClass).joinedload("widgets")
+
+    The above ``myopt`` can now be used with :meth:`.Query.options`::
+
+        session.query(MyClass).options(myopt)
+
+    The :class:`.Load` construct is invoked indirectly whenever one makes use
+    of the various loader options that are present in ``sqlalchemy.orm``,
+    including options such as :func:`.orm.joinedload`, :func:`.orm.defer`,
+    :func:`.orm.subqueryload`, and all the rest.  These constructs produce an
+    "anonymous" form of the :class:`.Load` object which tracks attributes and
+    options, but is not linked to a parent class until it is associated with a
+    parent :class:`.Query`::
+
+        # produce "unbound" Load object
+        myopt = joinedload("widgets")
+
+        # when applied using options(), the option is "bound" to the
+        # class observed in the given query, e.g. MyClass
+        session.query(MyClass).options(myopt)
+
+    Whether the direct or indirect style is used, the :class:`.Load` object
+    returned now represents a specific "path" along the entities of a
+    :class:`.Query`.  This path can be traversed using a standard
+    method-chaining approach.  Supposing a class hierarchy such as ``User``,
+    ``User.addresses -> Address``, ``User.orders -> Order`` and
+    ``Order.items -> Item``, we can specify a variety of loader options along
+    each element in the "path"::
+
+        session.query(User).options(
+                    joinedload("addresses"),
+                    subqueryload("orders").joinedload("items")
+                )
+
+    Where above, the ``addresses`` collection will be joined-loaded, the
+    ``orders`` collection will be subquery-loaded, and within that subquery
+    load the ``items`` collection will be joined-loaded.

+

+             **does not affect the behavior** of :meth:`.Engine.connect`.
+             :meth:`.Engine.connect` makes use of the

+             local context**.  To produce a :class:`.Connection` which refers
+             to the :meth:`.Pool.connect` method, use
+             :meth:`.Engine.contextual_connect`.

+             :meth:`.Engine.execute` as well as the orm
+             :class:`.Session` make use of
+             :meth:`.Engine.contextual_connect` internally, so these functions
+             are compatible with the :paramref:`.Pool.use_threadlocal` setting.
+
+          .. seealso::
+
+            :ref:`threadlocal_strategy` - contains detail on the
+            "threadlocal" engine strategy, which provides a more comprehensive
+            approach to "threadlocal" connectivity for the specific

+
+        :param reset_on_return: Determine steps to take on

+          reset_on_return can have any of these values:
+
+          * ``"rollback"`` - call rollback() on the connection,
+            to release locks and transaction resources.
+            This is the default value.  The vast majority
+            of use cases should leave this value set.
+          * ``True`` - same as 'rollback', this is here for
+            backwards compatibility.
+          * ``"commit"`` - call commit() on the connection,
+            to release locks and transaction resources.
+            A commit here may be desirable for databases that
+            cache query plans if a commit is emitted,
+            such as Microsoft SQL Server.  However, this
+            value is more dangerous than 'rollback' because
+            any data changes present on the transaction
+            are committed unconditionally.
+          * ``None`` - don't do anything on the connection.
+            This setting should only be made on a database
+            that has no transaction support at all,
+            namely MySQL MyISAM.   By not doing anything,
+            performance can be improved.   This
+            setting should **never be selected** for a
+            database that supports transactions,
+            as it will lead to deadlocks and stale
+            state.
+          * ``False`` - same as None, this is here for
+            backwards compatibility.

+            return text

+        from sqlalchemy import schema
+
+        metadata = MetaData()
+
+        table = Table('mytable', MetaData(),

+            )
+
+        metadata.create_all(conn)
+
+    Above, the directives we've added to the :attr:`.Column.info` collection
+    will be detected by our custom compilation scheme::
+
+        CREATE TABLE mytable (
+                x SPECIAL DIRECTIVE INTEGER NOT NULL,
+                y VARCHAR(50),
+                z SPECIAL DIRECTIVE VARCHAR(20),
+            PRIMARY KEY (x)
+        )
+
+    The :class:`.CreateColumn` construct can also be used to skip certain
+    columns when producing a ``CREATE TABLE``.  This is accomplished by
+    creating a compilation rule that conditionally returns ``None``.
+    This is essentially how to produce the same effect as using the
+    ``system=True`` argument on :class:`.Column`, which marks a column
+    as an implicitly-present "system" column.
+
+    For example, suppose we wish to produce a :class:`.Table` which skips
+    rendering of the Postgresql ``xmin`` column against the Postgresql
+    backend, but on other backends does render it, in anticipation of a
+    triggered rule.  A conditional compilation rule could skip this name only
+    on Postgresql::
+
+        from sqlalchemy.schema import CreateColumn
+
+        @compiles(CreateColumn, "postgresql")
+        def skip_xmin(element, compiler, **kw):
+            if element.element.name == 'xmin':
+                return None
+            else:
+                return compiler.visit_create_column(element, **kw)
+
+
+        my_table = Table('mytable', metadata,
+                    Column('id', Integer, primary_key=True),
+                    Column('xmin', Integer)
+                )
+
+    Above, a :class:`.CreateTable` construct will generate a ``CREATE TABLE``
+    which only includes the ``id`` column in the string; the ``xmin`` column
+    will be omitted, but only against the Postgresql backend.
+
+    .. versionadded:: 0.8.3 The :class:`.CreateColumn` construct supports

+       rule.

+         either through multiple :meth:`.ValuesBase.values` calls
+         or by sending a list + kwargs at the same time.
+
+         .. note::
+
+             Passing a multiple values list is *not* the same
+             as passing a multiple values list to the
+             :meth:`.Connection.execute` method.  Passing a list of parameter
+             sets to :meth:`.ValuesBase.values` produces a construct of this

+
+            server_created_at = result.returned_defaults['created_at']
+
+        When used against a backend that supports RETURNING, all column
+        values generated by SQL expression or server-side-default will be
+        added to any existing RETURNING clause, provided that
+        :meth:`.UpdateBase.returning` is not used simultaneously.  The column
+        values will then be available on the result using the
+        :attr:`.ResultProxy.returned_defaults` accessor as a dictionary,
+        referring to values keyed to the :class:`.Column` object as well as
+        its ``.key``.
+
+        This method differs from :meth:`.UpdateBase.returning` in these ways:
+
+        1. :meth:`.ValuesBase.return_defaults` is only intended for use with
+           an INSERT or an UPDATE statement that matches exactly one row.
+           While the RETURNING construct in the general sense supports
+           multiple rows for a multi-row UPDATE or DELETE statement, or for
+           special cases of INSERT that return multiple rows (e.g. INSERT from
+           SELECT, multi-valued VALUES clause),
+           :meth:`.ValuesBase.return_defaults` is intended only for an
+           "ORM-style" single-row INSERT/UPDATE statement.  The row returned
+           by the statement is also consumed implcitly when
+           :meth:`.ValuesBase.return_defaults` is used.  By contrast,
+           :meth:`.UpdateBase.returning` leaves the RETURNING result-set
+           intact with a collection of any number of rows.
+
+        2. It is compatible with the existing logic to fetch auto-generated
+           primary key values, also known as "implicit returning".  Backends
+           that support RETURNING will automatically make use of RETURNING in
+           order to fetch the value of newly generated primary keys; while the
+           :meth:`.UpdateBase.returning` method circumvents this behavior,
+           :meth:`.ValuesBase.return_defaults` leaves it intact.
+
+        3. It can be called against any backend.  Backends that don't support
+           RETURNING will skip the usage of the feature, rather than raising
+           an exception.  The return value of
+           :attr:`.ResultProxy.returned_defaults` will be ``None``
+
+        :meth:`.ValuesBase.return_defaults` is used by the ORM to provide

+class ColumnElement(operators.ColumnOperators, ClauseElement):
+    """Represent a column-oriented SQL expression suitable for usage in the
+    "columns" clause, WHERE clause etc. of a statement.
+
+    While the most familiar kind of :class:`.ColumnElement` is the
+    :class:`.Column` object, :class:`.ColumnElement` serves as the basis
+    for any unit that may be present in a SQL expression, including
+    the expressions themselves, SQL functions, bound parameters,
+    literal expressions, keywords such as ``NULL``, etc.
+    :class:`.ColumnElement` is the ultimate base class for all such elements.
+
+    A wide variety of SQLAlchemy Core functions work at the SQL expression
+    level, and are intended to accept instances of :class:`.ColumnElement` as
+    arguments.  These functions will typically document that they accept a
+    "SQL expression" as an argument.  What this means in terms of SQLAlchemy
+    usually refers to an input which is either already in the form of a
+    :class:`.ColumnElement` object, or a value which can be **coerced** into
+    one.  The coercion rules followed by most, but not all, SQLAlchemy Core
+    functions with regards to SQL expressions are as follows:
+
+        * a literal Python value, such as a string, integer or floating
+          point value, boolean, datetime, ``Decimal`` object, or virtually
+          any other Python object, will be coerced into a "literal bound
+          value".  This generally means that a :func:`.bindparam` will be
+          produced featuring the given value embedded into the construct; the
+          resulting :class:`.BindParameter` object is an instance of
+          :class:`.ColumnElement`.  The Python value will ultimately be sent
+          to the DBAPI at execution time as a paramterized argument to the
+          ``execute()`` or ``executemany()`` methods, after SQLAlchemy
+          type-specific converters (e.g. those provided by any associated
+          :class:`.TypeEngine` objects) are applied to the value.
+
+        * any special object value, typically ORM-level constructs, which
+          feature a method called ``__clause_element__()``.  The Core
+          expression system looks for this method when an object of otherwise
+          unknown type is passed to a function that is looking to coerce the
+          argument into a :class:`.ColumnElement` expression.  The
+          ``__clause_element__()`` method, if present, should return a
+          :class:`.ColumnElement` instance.  The primary use of
+          ``__clause_element__()`` within SQLAlchemy is that of class-bound
+          attributes on ORM-mapped classes; a ``User`` class which contains a
+          mapped attribute named ``.name`` will have a method
+          ``User.name.__clause_element__()`` which when invoked returns the
+          :class:`.Column` called ``name`` associated with the mapped table.
+
+        * The Python ``None`` value is typically interpreted as ``NULL``,
+          which in SQLAlchemy Core produces an instance of :func:`.null`.
+
+    A :class:`.ColumnElement` provides the ability to generate new
+    :class:`.ColumnElement`
+    objects using Python expressions.  This means that Python operators
+    such as ``==``, ``!=`` and ``<`` are overloaded to mimic SQL operations,
+    and allow the instantiation of further :class:`.ColumnElement` instances
+    which are composed from other, more fundamental :class:`.ColumnElement`
+    objects.  For example, two :class:`.ColumnClause` objects can be added
+    together with the addition operator ``+`` to produce
+    a :class:`.BinaryExpression`.
+    Both :class:`.ColumnClause` and :class:`.BinaryExpression` are subclasses
+    of :class:`.ColumnElement`::
+
+        >>> from sqlalchemy.sql import column
+        >>> column('a') + column('b')
+        <sqlalchemy.sql.expression.BinaryExpression object at 0x101029dd0>
+        >>> print column('a') + column('b')

+        "placeholder" value in a SQL expression, the value of which is
+        supplied at the point at which the statement in executed against a
+        database connection.
+
+        In SQLAlchemy, the :func:`.bindparam` construct has
+        the ability to carry along the actual value that will be ultimately
+        used at expression time.  In this way, it serves not just as
+        a "placeholder" for eventual population, but also as a means of
+        representing so-called "unsafe" values which should not be rendered
+        directly in a SQL statement, but rather should be passed along
+        to the :term:`DBAPI` as values which need to be correctly escaped
+        and potentially handled for type-safety.
+
+        When using :func:`.bindparam` explicitly, the use case is typically
+        one of traditional deferment of parameters; the :func:`.bindparam`
+        construct accepts a name which can then be referred to at execution
+        time::
+
+            from sqlalchemy import bindparam
+
+            stmt = select([users_table]).\\
+                        where(users_table.c.name == bindparam('username'))
+
+        The above statement, when rendered, will produce SQL similar to::
+
+            SELECT id, name FROM user WHERE name = :username
+
+        In order to populate the value of ``:username`` above, the value
+        would typically be applied at execution time to a method
+        like :meth:`.Connection.execute`::
+
+            result = connection.execute(stmt, username='wendy')
+
+        Explicit use of :func:`.bindparam` is also common when producing
+        UPDATE or DELETE statements that are to be invoked multiple times,
+        where the WHERE criterion of the statement is to change on each
+        invocation, such as::
+
+            stmt = (users_table.update().
+                    where(user_table.c.name == bindparam('username')).
+                    values(fullname=bindparam('fullname'))
+                    )
+
+            connection.execute(
+                stmt, [{"username": "wendy", "fullname": "Wendy Smith"},
+                       {"username": "jack", "fullname": "Jack Jones"},
+                       ]
+            )
+
+        SQLAlchemy's Core expression system makes wide use of
+        :func:`.bindparam` in an implicit sense.   It is typical that Python
+        literal values passed to virtually all SQL expression functions are
+        coerced into fixed :func:`.bindparam` constructs.  For example, given
+        a comparison operation such as::
+
+            expr = users_table.c.name == 'Wendy'
+
+        The above expression will produce a :class:`.BinaryExpression`
+        construct, where the left side is the :class:`.Column` object
+        representing the ``name`` column, and the right side is a
+        :class:`.BindParameter` representing the literal value::
+
+            print(repr(expr.right))
+            BindParameter('%(4327771088 name)s', 'Wendy', type_=String())
+
+        The expression above will render SQL such as::
+
+            user.name = :name_1
+
+        Where the ``:name_1`` parameter name is an anonymous name.  The
+        actual string ``Wendy`` is not in the rendered string, but is carried
+        along where it is later used within statement execution.  If we
+        invoke a statement like the following::
+
+            stmt = select([users_table]).where(users_table.c.name == 'Wendy')
+            result = connection.execute(stmt)
+
+        We would see SQL logging output as::
+
+            SELECT "user".id, "user".name
+            FROM "user"
+            WHERE "user".name = %(name_1)s
+            {'name_1': 'Wendy'}
+
+        Above, we see that ``Wendy`` is passed as a parameter to the database,
+        while the placeholder ``:name_1`` is rendered in the appropriate form
+        for the target database, in this case the Postgresql database.
+
+        Similarly, :func:`.bindparam` is invoked automatically
+        when working with :term:`CRUD` statements as far as the "VALUES"
+        portion is concerned.   The :func:`.insert` construct produces an
+        ``INSERT`` expression which will, at statement execution time,
+        generate bound placeholders based on the arguments passed, as in::
+
+            stmt = users_table.insert()
+            result = connection.execute(stmt, name='Wendy')
+
+        The above will produce SQL output as::
+
+            INSERT INTO "user" (name) VALUES (%(name)s)
+            {'name': 'Wendy'}
+
+        The :class:`.Insert` construct, at compilation/execution time,
+        rendered a single :func:`.bindparam` mirroring the column
+        name ``name`` as a result of the single ``name`` parameter
+        we passed to the :meth:`.Connection.execute` method.
+
+        :param key:
+          the key (e.g. the name) for this bind param.
+          Will be used in the generated
+          SQL statement for dialects that use named parameters.  This
+          value may be modified when part of a compilation operation,
+          if other :class:`BindParameter` objects exist with the same
+          key, or if its length is too long and truncation is
+          required.
+
+        :param value:
+          Initial value for this bind param.  Will be used at statement
+          execution time as the value for this parameter passed to the
+          DBAPI, if no other value is indicated to the statement execution
+          method for this particular parameter name.  Defaults to ``None``.
+
+        :param callable\_:
+          A callable function that takes the place of "value".  The function
+          will be called at statement execution time to determine the
+          ultimate value.   Used for scenarios where the actual bind
+          value cannot be determined at the point at which the clause
+          construct is created, but embedded bind values are still desirable.
+
+        :param type\_:
+          A :class:`.TypeEngine` class or instance representing an optional
+          datatype for this :func:`.bindparam`.  If not passed, a type
+          may be determined automatically for the bind, based on the given
+          value; for example, trivial Python types such as ``str``,
+          ``int``, ``bool``
+          may result in the :class:`.String`, :class:`.Integer` or
+          :class:`.Boolean` types being autoamtically selected.
+
+          The type of a :func:`.bindparam` is significant especially in that
+          the type will apply pre-processing to the value before it is
+          passed to the database.  For example, a :func:`.bindparam` which
+          refers to a datetime value, and is specified as holding the
+          :class:`.DateTime` type, may apply conversion needed to the
+          value (such as stringification on SQLite) before passing the value
+          to the database.
+
+        :param unique:
+          if True, the key name of this :class:`.BindParameter` will be
+          modified if another :class:`.BindParameter` of the same name
+          already has been located within the containing
+          expression.  This flag is used generally by the internals
+          when producing so-called "anonymous" bound expressions, it
+          isn't generally applicable to explicitly-named :func:`.bindparam`
+          constructs.
+
+        :param required:

+
+            t = text("SELECT * FROM users")
+            result = connection.execute(t)
+
+        The advantages :func:`.text` provides over a plain string are
+        backend-neutral support for bind parameters, per-statement
+        execution options, as well as
+        bind parameter and result-column typing behavior, allowing
+        SQLAlchemy type constructs to play a role when executing
+        a statement that is specified literally.  The construct can also
+        be provided with a ``.c`` collection of column elements, allowing
+        it to be embedded in other SQL expression constructs as a subquery.
+
+        Bind parameters are specified by name, using the format ``:name``.
+        E.g.::
+
+            t = text("SELECT * FROM users WHERE id=:user_id")
+            result = connection.execute(t, user_id=12)
+
+        For SQL statements where a colon is required verbatim, as within
+        an inline string, use a backslash to escape::
+
+            t = text("SELECT * FROM users WHERE name='\\:username'")
+
+        The :class:`.TextClause` construct includes methods which can
+        provide information about the bound parameters as well as the column
+        values which would be returned from the textual statement, assuming
+        it's an executable SELECT type of statement.  The
+        :meth:`.TextClause.bindparams` method is used to provide bound
+        parameter detail, and :meth:`.TextClause.columns` method allows
+        specification of return columns including names and types::
+
+            t = text("SELECT * FROM users WHERE id=:user_id").\\
+                    bindparams(user_id=7).\\
+                    columns(id=Integer, name=String)
+
+            for id, name in connection.execute(t):
+                print(id, name)
+
+        The :func:`.text` construct is used internally in cases when
+        a literal string is specified for part of a larger query, such as
+        when a string is specified to the :meth:`.Select.where` method of
+        :class:`.Select`.  In those cases, the same
+        bind parameter syntax is applied::
+
+            s = select([users.c.id, users.c.name]).where("id=:user_id")
+            result = connection.execute(s, user_id=12)
+
+        Using :func:`.text` explicitly usually implies the construction
+        of a full, standalone statement.   As such, SQLAlchemy refers
+        to it as an :class:`.Executable` object, and it supports
+        the :meth:`Executable.execution_options` method.  For example,
+        a :func:`.text` construct that should be subject to "autocommit"
+        can be set explicitly so using the
+        :paramref:`.Connection.execution_options.autocommit` option::
+
+            t = text("EXEC my_procedural_thing()").\\
+                    execution_options(autocommit=True)
+
+        Note that SQLAlchemy's usual "autocommit" behavior applies to
+        :func:`.text` constructs implicitly - that is, statements which begin
+        with a phrase such as ``INSERT``, ``UPDATE``, ``DELETE``,
+        or a variety of other phrases specific to certain backends, will
+        be eligible for autocommit if no transaction is in progress.
+
+        :param text:
+          the text of the SQL statement to be created.  use ``:<param>``
+          to specify bind parameters; they will be compiled to their
+          engine-specific format.
+
+        :param autocommit:
+          Deprecated.  Use .execution_options(autocommit=<True|False>)
+          to set the autocommit option.
+

+          This argument now invokes the :meth:`.TextClause.bindparams`
+          method on the construct before returning it.  E.g.::
+
+              stmt = text("SELECT * FROM table WHERE id=:id",
+                        bindparams=[bindparam('id', value=5, type_=Integer)])

+
+          .. deprecated:: 0.9.0 the :meth:`.TextClause.bindparams` method

+          :class:`.TextAsFrom` construct that gains a ``.c`` collection and
+          can be embedded in other expressions.  E.g.::
+
+              stmt = text("SELECT * FROM table",

+        bind.  In the case of ``name`` we also set the default value of

+

+        This function essentially bridges the gap between an entirely
+        textual SELECT statement and the SQL expression language concept
+        of a "selectable"::
+
+            from sqlalchemy.sql import column, text
+
+            stmt = text("SELECT id, name FROM some_table")
+            stmt = stmt.columns(column('id'), column('name')).alias('st')
+
+            stmt = select([mytable]).\\
+                    select_from(
+                        mytable.join(stmt, mytable.c.name == stmt.c.name)
+                    ).where(stmt.c.id > 5)
+
+        Above, we used untyped :func:`.column` elements.  These can also have
+        types specified, which will impact how the column behaves in
+        expressions as well as determining result set behavior::
+
+            stmt = text("SELECT id, name, timestamp FROM some_table")
+            stmt = stmt.columns(
+                        column('id', Integer),
+                        column('name', Unicode),
+                        column('timestamp', DateTime)
+                    )
+
+            for id, name, timestamp in connection.execute(stmt):
+                print(id, name, timestamp)
+
+        Keyword arguments allow just the names and types of columns to be
+        specified, where the :func:`.column` elements will be generated
+        automatically::
+
+            stmt = text("SELECT id, name, timestamp FROM some_table")
+            stmt = stmt.columns(
+                        id=Integer,
+                        name=Unicode,
+                        timestamp=DateTime
+                    )
+
+            for id, name, timestamp in connection.execute(stmt):
+                print(id, name, timestamp)
+
+        The :meth:`.TextClause.columns` method provides a direct
+        route to calling :meth:`.FromClause.alias` as well as
+        :meth:`.SelectBase.cte` against a textual SELECT statement::
+
+            stmt = stmt.columns(id=Integer, name=String).cte('st')
+
+            stmt = select([sometable]).where(sometable.c.id == stmt.c.id)
+
+        .. versionadded:: 0.9.0 :func:`.text` can now be converted into a
+           fully featured "selectable" construct using the
+           :meth:`.TextClause.columns` method.  This method supersedes the
+           ``typemap`` argument to :func:`.text`.

+
+        The ``CASE`` construct in SQL is a conditional object that
+        acts somewhat analogously to an "if/then" construct in other
+        languages.  It returns an instance of :class:`.Case`.
+
+        :func:`.case` in its usual form is passed a list of "when"
+        constructs, that is, a list of conditions and results as tuples::
+
+            from sqlalchemy import case
+
+            stmt = select([users_table]).\\
+                        where(
+                            case(
+                                [
+                                    (users_table.c.name == 'wendy', 'W'),
+                                    (users_table.c.name == 'jack', 'J')
+                                ],
+                                else_='E'
+                            )
+                        )
+
+        The above statement will produce SQL resembling::
+
+            SELECT id, name FROM user
+            WHERE CASE
+                WHEN (name = :name_1) THEN :param_1

+                ELSE :param_3
+            END
+
+        When simple equality expressions of several values against a single
+        parent column are needed, :func:`.case` also has a "shorthand" format
+        used via the
+        :paramref:`.case.value` parameter, which is passed a column
+        expression to be compared.  In this form, the :paramref:`.case.whens`
+        parameter is passed as a dictionary containing expressions to be
+        compared against keyed to result expressions.  The statement below is
+        equivalent to the preceding statement::
+
+            stmt = select([users_table]).\\
+                        where(
+                            case(
+                                {"wendy": "W", "jack": "J"},
+                                value=users_table.c.name,
+                                else_='E'
+                            )
+                        )
+
+        The values which are accepted as result values in
+        :paramref:`.case.whens` as well as with :paramref:`.case.else_` are
+        coerced from Python literals into :func:`.bindparam` constructs.
+        SQL expressions, e.g. :class:`.ColumnElement` constructs, are accepted
+        as well.  To coerce a literal string expression into a constant
+        expression rendered inline, use the :func:`.literal_column` construct,
+        as in::
+
+            from sqlalchemy import case, literal_column
+
+            case(
+                [
+                    (
+                        orderline.c.qty > 100,
+                        literal_column("'greaterthan100'")
+                    ),
+                    (
+                        orderline.c.qty > 10,
+                        literal_column("'greaterthan10'")
+                    )
+                ],
+                else_=literal_column("'lessthan10'")
+            )
+
+        The above will render the given constants without using bound
+        parameters for the result values (but still for the comparison
+        values), as in::
+
+            CASE
+                WHEN (orderline.qty > :qty_1) THEN 'greaterthan100'
+                WHEN (orderline.qty > :qty_2) THEN 'greaterthan10'
+                ELSE 'lessthan10'
+            END
+
+        :param whens: The criteria to be compared against,
+         :paramref:`.case.whens` accepts two different forms, based on
+         whether or not :paramref:`.case.value` is used.
+
+         In the first form, it accepts a list of 2-tuples; each 2-tuple
+         consists of ``(<sql expression>, <value>)``, where the SQL
+         expression is a boolean expression and "value" is a resulting value,
+         e.g.::
+
+            case([
+                (users_table.c.name == 'wendy', 'W'),
+                (users_table.c.name == 'jack', 'J')
+            ])
+
+         In the second form, it accepts a Python dictionary of comparison
+         values mapped to a resulting value; this form requires
+         :paramref:`.case.value` to be present, and values will be compared
+         using the ``==`` operator, e.g.::
+
+            case(
+                {"wendy": "W", "jack": "J"},
+                value=users_table.c.name
+            )
+
+        :param value: An optional SQL expression which will be used as a
+          fixed "comparison point" for candidate values within a dictionary
+          passed to :paramref:`.case.whens`.
+
+        :param else\_: An optional SQL expression which will be the evaluated
+          result of the ``CASE`` construct if all expressions within
+          :paramref:`.case.whens` evaluate to false.  When omitted, most
+          databases will produce a result of NULL if none of the "when"

+
+    :class:`.quoted_name` is a Python unicode/str subclass which
+    represents a particular identifier name along with a
+    ``quote`` flag.  This ``quote`` flag, when set to
+    ``True`` or ``False``, overrides automatic quoting behavior
+    for this identifier in order to either unconditionally quote
+    or to not quote the name.  If left at its default of ``None``,
+    quoting behavior is applied to the identifier on a per-backend basis
+    based on an examination of the token itself.
+
+    A :class:`.quoted_name` object with ``quote=True`` is also
+    prevented from being modified in the case of a so-called
+    "name normalize" option.  Certain database backends, such as
+    Oracle, Firebird, and DB2 "normalize" case-insensitive names
+    as uppercase.  The SQLAlchemy dialects for these backends
+    convert from SQLAlchemy's lower-case-means-insensitive convention
+    to the upper-case-means-insensitive conventions of those backends.
+    The ``quote=True`` flag here will prevent this conversion from occurring
+    to support an identifier that's quoted as all lower case against
+    such a backend.
+
+    The :class:`.quoted_name` object is normally created automatically
+    when specifying the name for key schema constructs such as
+    :class:`.Table`, :class:`.Column`, and others.  The class can also be
+    passed explicitly as the name to any function that receives a name which
+    can be quoted.  Such as to use the :meth:`.Engine.has_table` method with
+    an unconditionally quoted name::
+
+        from sqlaclchemy import create_engine
+        from sqlalchemy.sql.elements import quoted_name
+
+        engine = create_engine("oracle+cx_oracle://some_dsn")
+        engine.has_table(quoted_name("some_table", True))
+
+    The above logic will run the "has table" logic against the Oracle backend,
+    passing the name exactly as ``"some_table"`` without converting to
+    upper case.

+    The name of the above constraint will be rendered as ``"ck_t_x5"``.
+    That is, the existing name ``x5`` is used in the naming convention as the
+    ``constraint_name`` token.
+
+    In some situations, such as in migration scripts, we may be rendering
+    the above :class:`.CheckConstraint` with a name that's already been

+
+        m = MetaData(naming_convention={

+                        CheckConstraint('x > 5', name=conv('ck_t_x5')))
+
+    Where above, the :func:`.schema.conv` marker indicates that the constraint
+    name here is final, and the name will render as ``"ck_t_x5"`` and not

+        count(:param_1)
+
+   The element is a column-oriented SQL element like any other, and is
+   used in that way::
+
+        >>> print select([func.count(table.c.id)])
+        SELECT count(sometable.id) FROM sometable
+
+   Any name can be given to :data:`.func`. If the function name is unknown to
+   SQLAlchemy, it will be rendered exactly as is. For common SQL functions
+   which SQLAlchemy is aware of, the name may be interpreted as a *generic
+   function* which will be compiled appropriately to the target database::
+
+        >>> print func.current_timestamp()
+        CURRENT_TIMESTAMP
+
+   To call functions which are present in dot-separated packages,

+        >>> print func.stats.yield_curve(5, 10)
+        stats.yield_curve(:yield_curve_1, :yield_curve_2)
+
+   SQLAlchemy can be made aware of the return type of functions to enable
+   type-specific lexical and result-based behavior. For example, to ensure
+   that a string-based function returns a Unicode value and is similarly
+   treated as a string in expressions, specify
+   :class:`~sqlalchemy.types.Unicode` as the type:
+
+        >>> print func.my_string(u'hi', type_=Unicode) + ' ' + \
+        ... func.my_string(u'there', type_=Unicode)
+        my_string(:my_string_1) || :my_string_2 || my_string(:my_string_3)
+
+   The object returned by a :data:`.func` call is usually an instance of
+   :class:`.Function`.
+   This object meets the "column" interface, including comparison and labeling
+   functions.  The object can also be passed the :meth:`~.Connectable.execute`
+   method of a :class:`.Connection` or :class:`.Engine`, where it will be
+   wrapped inside of a SELECT statement first::
+
+        print connection.execute(func.current_timestamp()).scalar()
+
+   In a few exception cases, the :data:`.func` accessor
+   will redirect a name to a built-in expression such as :func:`.cast`
+   or :func:`.extract`, as these names have well-known meaning
+   but are not exactly the same as "functions" from a SQLAlchemy
+   perspective.
+
+   .. versionadded:: 0.8 :data:`.func` can return non-function expression
+      constructs for common quasi-functional names like :func:`.cast`
+      and :func:`.extract`.

+
+    A generic function is a pre-established :class:`.Function`

+    by name from the :data:`.func` attribute.    Note that
+    calling any name from :data:`.func` has the effect that
+    a new :class:`.Function` instance is created automatically,
+    given that name.  The primary use case for defining
+    a :class:`.GenericFunction` class is so that a function
+    of a particular name may be given a fixed return type.
+    It can also include custom argument parsing schemes as well
+    as additional methods.
+
+    Subclasses of :class:`.GenericFunction` are automatically
+    registered under the name of the class.  For
+    example, a user-defined function ``as_utc()`` would
+    be available immediately::
+

+        from sqlalchemy.types import DateTime
+
+        class as_utc(GenericFunction):
+            type = DateTime
+
+        print select([func.as_utc()])
+
+    User-defined generic functions can be organized into
+    packages by specifying the "package" attribute when defining
+    :class:`.GenericFunction`.   Third party libraries
+    containing many functions may want to use this in order
+    to avoid name conflicts with other systems.   For example,
+    if our ``as_utc()`` function were part of a package
+    "time"::
+
+        class as_utc(GenericFunction):
+            type = DateTime
+            package = "time"
+
+    The above function would be available from :data:`.func`
+    using the package name ``time``::
+

+"""The schema module provides the building blocks for database metadata.
+
+Each element within this module describes a database entity which can be
+created and dropped, or is otherwise part of such an entity.  Examples include
+tables, columns, sequences, and indexes.
+
+All entities are subclasses of :class:`~sqlalchemy.schema.SchemaItem`, and as
+defined in this module they are intended to be agnostic of any vendor-specific
+constructs.
+
+A collection of entities are grouped into a unit called
+:class:`~sqlalchemy.schema.MetaData`. MetaData serves as a logical grouping of
+schema elements, and can also be associated with an actual database connection
+such that operations involving the contained elements can contact the database
+as needed.
+
+Two of the elements here also build upon their "syntactic" counterparts, which
+are defined in :class:`~sqlalchemy.sql.expression.`, specifically
+:class:`~sqlalchemy.schema.Table` and :class:`~sqlalchemy.schema.Column`.
+Since these objects are part of the SQL expression language, they are usable
+as components in SQL expressions.

+    The :class:`.Table` object constructs a unique instance of itself based
+    on its name and optional schema name within the given
+    :class:`.MetaData` object. Calling the :class:`.Table`
+    constructor with the same name and same :class:`.MetaData` argument
+    a second time will return the *same* :class:`.Table` object - in this way
+    the :class:`.Table` constructor acts as a registry function.
+
+    .. seealso::
+
+        :ref:`metadata_describing` - Introduction to database metadata
+
+    Constructor arguments are as follows:
+
+    :param name: The name of this table as represented in the database.
+
+        The table name, along with the value of the ``schema`` parameter,
+        forms a key which uniquely identifies this :class:`.Table` within
+        the owning :class:`.MetaData` collection.
+        Additional calls to :class:`.Table` with the same name, metadata,
+        and schema name will return the same :class:`.Table` object.
+
+        Names which contain no upper case characters
+        will be treated as case insensitive names, and will not be quoted
+        unless they are a reserved word or contain special characters.
+        A name with any number of upper case characters is considered
+        to be case sensitive, and will be sent as quoted.
+
+        To enable unconditional quoting for the table name, specify the flag
+        ``quote=True`` to the constructor, or use the :class:`.quoted_name`
+        construct to specify the name.
+
+    :param metadata: a :class:`.MetaData` object which will contain this
+        table.  The metadata is used as a point of association of this table
+        with other tables which are referenced via foreign key.  It also
+        may be used to associate this table with a particular
+        :class:`.Connectable`.
+
+    :param \*args: Additional positional arguments are used primarily
+        to add the list of :class:`.Column` objects contained within this
+        table. Similar to the style of a CREATE TABLE statement, other
+        :class:`.SchemaItem` constructs may be added here, including
+        :class:`.PrimaryKeyConstraint`, and :class:`.ForeignKeyConstraint`.
+
+    :param autoload: Defaults to False: the Columns for this table should
+        be reflected from the database. Usually there will be no Column
+        objects in the constructor if this property is set.
+
+    :param autoload_replace: If ``True``, when using ``autoload=True``
+        and ``extend_existing=True``,
+        replace ``Column`` objects already present in the ``Table`` that's
+        in the ``MetaData`` registry with
+        what's reflected.  Otherwise, all existing columns will be
+        excluded from the reflection process.    Note that this does
+        not impact ``Column`` objects specified in the same call to ``Table``
+        which includes ``autoload``, those always take precedence.
+        Defaults to ``True``.
+
+        .. versionadded:: 0.7.5
+
+    :param autoload_with: If autoload==True, this is an optional Engine
+        or Connection instance to be used for the table reflection. If
+        ``None``, the underlying MetaData's bound connectable will be used.
+
+    :param extend_existing: When ``True``, indicates that if this
+        :class:`.Table` is already present in the given :class:`.MetaData`,
+        apply further arguments within the constructor to the existing
+        :class:`.Table`.
+
+        If ``extend_existing`` or ``keep_existing`` are not set, an error is
+        raised if additional table modifiers are specified when
+        the given :class:`.Table` is already present in the
+        :class:`.MetaData`.
+
+        .. versionchanged:: 0.7.4
+            ``extend_existing`` will work in conjunction
+            with ``autoload=True`` to run a new reflection operation against
+            the database; new :class:`.Column` objects will be produced
+            from database metadata to replace those existing with the same
+            name, and additional :class:`.Column` objects not present
+            in the :class:`.Table` will be added.
+
+        As is always the case with ``autoload=True``, :class:`.Column`
+        objects can be specified in the same :class:`.Table` constructor,
+        which will take precedence.  I.e.::
+
+            Table("mytable", metadata,
+                        Column('y', Integer),
+                        extend_existing=True,
+                        autoload=True,
+                        autoload_with=engine
+                    )
+
+        The above will overwrite all columns within ``mytable`` which
+        are present in the database, except for ``y`` which will be used as is
+        from the above definition.   If the ``autoload_replace`` flag
+        is set to False, no existing columns will be replaced.
+
+    :param implicit_returning: True by default - indicates that
+        RETURNING can be used by default to fetch newly inserted primary key
+        values, for backends which support this.  Note that
+        create_engine() also provides an implicit_returning flag.
+
+    :param include_columns: A list of strings indicating a subset of
+        columns to be loaded via the ``autoload`` operation; table columns who
+        aren't present in this list will not be represented on the resulting
+        ``Table`` object. Defaults to ``None`` which indicates all columns
+        should be reflected.
+
+    :param info: Optional data dictionary which will be populated into the
+        :attr:`.SchemaItem.info` attribute of this object.
+
+    :param keep_existing: When ``True``, indicates that if this Table
+        is already present in the given :class:`.MetaData`, ignore
+        further arguments within the constructor to the existing
+        :class:`.Table`, and return the :class:`.Table` object as
+        originally created. This is to allow a function that wishes
+        to define a new :class:`.Table` on first call, but on
+        subsequent calls will return the same :class:`.Table`,
+        without any of the declarations (particularly constraints)
+        being applied a second time. Also see extend_existing.
+
+        If extend_existing or keep_existing are not set, an error is
+        raised if additional table modifiers are specified when
+        the given :class:`.Table` is already present in the
+        :class:`.MetaData`.
+
+    :param listeners: A list of tuples of the form ``(<eventname>, <fn>)``
+        which will be passed to :func:`.event.listen` upon construction.
+        This alternate hook to :func:`.event.listen` allows the establishment
+        of a listener function specific to this :class:`.Table` before
+        the "autoload" process begins.  Particularly useful for
+        the :meth:`.DDLEvents.column_reflect` event::
+
+            def listen_for_reflect(table, column_info):
+                "handle the column reflection event"
+                # ...
+
+            t = Table(
+                'sometable',
+                autoload=True,
+                listeners=[
+                    ('column_reflect', listen_for_reflect)
+                ])
+
+    :param mustexist: When ``True``, indicates that this Table must already
+        be present in the given :class:`.MetaData` collection, else
+        an exception is raised.
+
+    :param prefixes:
+        A list of strings to insert after CREATE in the CREATE TABLE
+        statement.  They will be separated by spaces.
+
+    :param quote: Force quoting of this table's name on or off, corresponding
+        to ``True`` or ``False``.  When left at its default of ``None``,
+        the column identifier will be quoted according to whether the name is
+        case sensitive (identifiers with at least one upper case character are
+        treated as case sensitive), or if it's a reserved word.  This flag
+        is only needed to force quoting of a reserved word which is not known
+        by the SQLAlchemy dialect.
+
+    :param quote_schema: same as 'quote' but applies to the schema identifier.
+
+    :param schema: The schema name for this table, which is required if
+        the table resides in a schema other than the default selected schema
+        for the engine's database connection.  Defaults to ``None``.
+
+        The quoting rules for the schema name are the same as those for the
+        ``name`` parameter, in that quoting is applied for reserved words or
+        case-sensitive names; to enable unconditional quoting for the
+        schema name, specify the flag
+        ``quote_schema=True`` to the constructor, or use the
+        :class:`.quoted_name` construct to specify the name.
+
+    :param useexisting: Deprecated.  Use extend_existing.
+
+    :param \**kw: Additional keyword arguments not mentioned above are
+        dialect specific, and passed in the form ``<dialectname>_<argname>``.
+        See the documentation regarding an individual dialect at
+        :ref:`dialect_toplevel` for detail on documented arguments.

+          well, at the moment that the foreign key is resolved against that
+          remote :class:`.Column` object.

+          as options to the column.  These include instances of
+          :class:`.Constraint`, :class:`.ForeignKey`, :class:`.ColumnDefault`,
+          and :class:`.Sequence`.  In some cases an equivalent keyword
+          argument is available such as ``server_default``, ``default``
+          and ``unique``.
+
+        :param autoincrement: This flag may be set to ``False`` to
+          indicate an integer primary key column that should not be
+          considered to be the "autoincrement" column, that is
+          the integer primary key column which generates values
+          implicitly upon INSERT and whose value is usually returned
+          via the DBAPI cursor.lastrowid attribute.   It defaults
+          to ``True`` to satisfy the common use case of a table
+          with a single integer primary key column.  If the table
+          has a composite primary key consisting of more than one
+          integer column, set this flag to True only on the
+          column that should be considered "autoincrement".
+
+          The setting *only* has an effect for columns which are:
+
+          * Integer derived (i.e. INT, SMALLINT, BIGINT).
+
+          * Part of the primary key
+
+          * Not refering to another column via :class:`.ForeignKey`, unless

+                            primary_key=True, autoincrement='ignore_fk')
+
+            It is typically not desirable to have "autoincrement" enabled
+            on such a column as its value intends to mirror that of a
+            primary key column elsewhere.
+
+          * have no server side or client side defaults (with the exception
+            of Postgresql SERIAL).
+
+          The setting has these two effects on columns that meet the
+          above criteria:
+
+          * DDL issued for the column will include database-specific
+            keywords intended to signify this column as an
+            "autoincrement" column, such as AUTO INCREMENT on MySQL,
+            SERIAL on Postgresql, and IDENTITY on MS-SQL.  It does
+            *not* issue AUTOINCREMENT for SQLite since this is a
+            special SQLite flag that is not required for autoincrementing
+            behavior.
+
+            .. seealso::
+
+                :ref:`sqlite_autoincrement`
+
+          * The column will be considered to be available as

+            "post fetch" newly inserted identifiers after a row has
+            been inserted (SQLite, MySQL, MS-SQL).  It does not have
+            any effect in this regard for databases that use sequences
+            to generate primary key identifiers (i.e. Firebird, Postgresql,
+            Oracle).
+
+          .. versionchanged:: 0.7.4
+              ``autoincrement`` accepts a special value ``'ignore_fk'``
+              to indicate that autoincrementing status regardless of foreign
+              key references.  This applies to certain composite foreign key
+              setups, such as the one demonstrated in the ORM documentation
+              at :ref:`post_update`.
+
+        :param default: A scalar, Python callable, or
+            :class:`.ColumnElement` expression representing the
+            *default value* for this column, which will be invoked upon insert
+            if this column is otherwise not specified in the VALUES clause of
+            the insert. This is a shortcut to using :class:`.ColumnDefault` as
+            a positional argument; see that class for full detail on the
+            structure of the argument.
+
+            Contrast this argument to ``server_default`` which creates a
+            default generator on the database side.
+
+        :param doc: optional String that can be used by the ORM or similar
+            to document attributes.   This attribute does not render SQL
+            comments (a future attribute 'comment' will achieve that).
+
+        :param key: An optional string identifier which will identify this

+            application, including ORM attribute mapping; the ``name`` field
+            is used only when rendering SQL.
+
+        :param index: When ``True``, indicates that the column is indexed.
+            This is a shortcut for using a :class:`.Index` construct on the
+            table. To specify indexes with explicit names or indexes that
+            contain multiple columns, use the :class:`.Index` construct
+            instead.
+

+            :attr:`.SchemaItem.info` attribute of this object.
+
+        :param nullable: If set to the default of ``True``, indicates the
+            column will be rendered as allowing NULL, else it's rendered as
+            NOT NULL. This parameter is only used when issuing CREATE TABLE
+            statements.
+
+        :param onupdate: A scalar, Python callable, or
+            :class:`~sqlalchemy.sql.expression.ClauseElement` representing a
+            default value to be applied to the column within UPDATE
+            statements, which wil be invoked upon update if this column is not
+            present in the SET clause of the update. This is a shortcut to
+            using :class:`.ColumnDefault` as a positional argument with
+            ``for_update=True``.
+
+        :param primary_key: If ``True``, marks this column as a primary key
+            column. Multiple columns can have this flag set to specify
+            composite primary keys. As an alternative, the primary key of a
+            :class:`.Table` can be specified via an explicit
+            :class:`.PrimaryKeyConstraint` object.
+
+        :param server_default: A :class:`.FetchedValue` instance, str, Unicode
+            or :func:`~sqlalchemy.sql.expression.text` construct representing
+            the DDL DEFAULT value for the column.

+             and the implementation is left to the database, such as via a

+
+        :param quote: Force quoting of this column's name on or off,
+             corresponding to ``True`` or ``False``. When left at its default
+             of ``None``, the column identifier will be quoted according to
+             whether the name is case sensitive (identifiers with at least one
+             upper case character are treated as case sensitive), or if it's a
+             reserved word. This flag is only needed to force quoting of a
+             reserved word which is not known by the SQLAlchemy dialect.
+
+        :param unique: When ``True``, indicates that this column contains a
+             unique constraint, or if ``index`` is ``True`` as well, indicates
+             that the :class:`.Index` should be created with the unique flag.
+             To specify multiple columns in the constraint/index or to specify
+             an explicit name, use the :class:`.UniqueConstraint` or
+             :class:`.Index` constructs explicitly.
+
+        :param system: When ``True``, indicates this is a "system" column,
+             that is a column which is automatically made available by the
+             database, and should not be included in the columns list for a
+             ``CREATE TABLE`` statement.
+
+             For more elaborate scenarios where columns should be
+             conditionally rendered differently on different backends,

+        Index("some_index", sometable.c.name, sometable.c.address)
+
+    Functional indexes are supported as well, typically by using the
+    :data:`.func` construct in conjunction with table-bound
+    :class:`.Column` objects::
+
+        Index("some_index", func.lower(sometable.c.name))
+
+    .. versionadded:: 0.8 support for functional and expression-based indexes.
+
+    An :class:`.Index` can also be manually associated with a :class:`.Table`,
+    either through inline declaration or using
+    :meth:`.Table.append_constraint`.  When this approach is used, the names
+    of the indexed columns can be specified as strings::
+
+        Table("sometable", metadata,
+                        Column("name", String(50)),
+                        Column("address", String(100)),
+                        Index("some_index", "name", "address")
+                )
+
+    To support functional or expression-based indexes in this form, the
+    :func:`.text` construct may be used::
+
+        from sqlalchemy import text
+
+        Table("sometable", metadata,
+                        Column("name", String(50)),
+                        Column("address", String(100)),
+                        Index("some_index", text("lower(name)"))
+                )
+
+    .. versionadded:: 0.9.5 the :func:`.text` construct may be used to
+       specify :class:`.Index` expressions, provided the :class:`.Index`
+       is explicitly associated with the :class:`.Table`.

+            primary key, index, check, and unique constraint, respectively.
+
+          * the string name of a user-defined "token" that can be used
+            to define new naming tokens.
+
+          The values associated with each "constraint class" or "constraint
+          mnemonic" key are string naming templates, such as
+          ``"uq_%(table_name)s_%(column_0_name)s"``,
+          which describe how the name should be composed.  The values
+          associated with user-defined "token" keys should be callables of the
+          form ``fn(constraint, table)``, which accepts the constraint/index
+          object and :class:`.Table` as arguments, returning a string
+          result.
+
+          The built-in names are as follows, some of which may only be

+
+            * ``%(table_name)s`` - the name of the :class:`.Table` object
+              associated with the constraint.
+
+            * ``%(referred_table_name)s`` - the name of the :class:`.Table`
+              object associated with the referencing target of a
+              :class:`.ForeignKeyConstraint`.
+
+            * ``%(column_0_name)s`` - the name of the :class:`.Column` at
+              index position "0" within the constraint.
+
+            * ``%(column_0_label)s`` - the label of the :class:`.Column` at
+              index position "0", e.g. :attr:`.Column.label`
+
+            * ``%(column_0_key)s`` - the key of the :class:`.Column` at
+              index position "0", e.g. :attr:`.Column.key`
+
+            * ``%(referred_column_0_name)s`` - the name of a :class:`.Column`
+              at index position "0" referenced by a
+              :class:`.ForeignKeyConstraint`.
+
+            * ``%(constraint_name)s`` - a special key that refers to the
+              existing name given to the constraint.  When this key is
+              present, the :class:`.Constraint` object's existing name will be
+              replaced with one that is composed from template string that
+              uses this token. When this token is present, it is required that
+              the :class:`.Constraint` is given an expicit name ahead of time.

+            j = alias(
+                select([j.left, j.right]).\\

+                    correlate(False),
+                name=name
+            )
+
+        The selectable produced by :meth:`.Join.alias` features the same
+        columns as that of the two individual selectables presented under
+        a single name - the individual columns are "auto-labeled", meaning
+        the ``.c.`` collection of the resulting :class:`.Alias` represents
+        the names of the individual columns using a
+        ``<tablename>_<columname>`` scheme::
+
+            j.c.table_a_id
+            j.c.table_b_a_id
+
+        :meth:`.Join.alias` also features an alternate
+        option for aliasing joins which produces no enclosing SELECT and
+        does not normally apply labels to the column names.  The
+        ``flat=True`` option will call :meth:`.FromClause.alias`
+        against the left and right sides individually.
+        Using this option, no new ``SELECT`` is produced;
+        we instead, from a construct as below::
+
+            j = table_a.join(table_b, table_a.c.id == table_b.c.a_id)
+            j = j.alias(flat=True)
+
+        we get a result like this::
+
+            table_a AS table_a_1 JOIN table_b AS table_b_1 ON
+            table_a_1.id = table_b_1.a_id
+
+        The ``flat=True`` argument is also propagated to the contained
+        selectables, so that a composite join such as::
+
+            j = table_a.join(
+                    table_b.join(table_c,
+                            table_b.c.id == table_c.c.b_id),
+                    table_b.c.a_id == table_a.c.id
+                ).alias(flat=True)
+
+        Will produce an expression like::
+
+            table_a AS table_a_1 JOIN (
+                    table_b AS table_b_1 JOIN table_c AS table_c_1
+                    ON table_b_1.id = table_c_1.b_id
+            ) ON table_a_1.id = table_b_1.a_id
+
+        The standalone :func:`~.expression.alias` function as well as the
+        base :meth:`.FromClause.alias` method also support the ``flat=True``
+        argument as a no-op, so that the argument can be passed to the

+            Due to a bug fix, this method has a slight
+            behavioral change as of version 0.7.3.
+            Prior to version 0.7.3, the FROM clause of
+            a :func:`.select` was calculated upfront and as new columns
+            were added; in 0.7.3 and later it's calculated
+            at compile time, fixing an issue regarding late binding
+            of columns to parent tables.  This changes the behavior of
+            :meth:`.Select.with_only_columns` in that FROM clauses no
+            longer represented in the new list are dropped,
+            but this behavior is more consistent in
+            that the FROM clauses are consistently derived from the
+            current columns clause.  The original intent of this method
+            is to allow trimming of the existing columns list to be fewer
+            columns than originally present; the use case of replacing
+            the columns list with an entirely different one hadn't
+            been anticipated until 0.7.3 was released; the usage
+            guidelines below illustrate how this should be done.
+
+        This method is exactly equivalent to as if the original
+        :func:`.select` had been called with the given columns
+        clause.   I.e. a statement::
+
+            s = select([table1.c.a, table1.c.b])
+            s = s.with_only_columns([table1.c.b])
+
+        should be exactly equivalent to::
+
+            s = select([table1.c.b])
+
+        This means that FROM clauses which are only derived
+        from the column list will be discarded if the new column
+        list no longer contains that FROM::
+
+            >>> table1 = table('t1', column('a'), column('b'))
+            >>> table2 = table('t2', column('a'), column('b'))
+            >>> s1 = select([table1.c.a, table2.c.b])
+            >>> print s1
+            SELECT t1.a, t2.b FROM t1, t2
+            >>> s2 = s1.with_only_columns([table2.c.b])
+            >>> print s2
+            SELECT t2.b FROM t1
+
+        The preferred way to maintain a specific FROM clause
+        in the construct, assuming it won't be represented anywhere
+        else (i.e. not in the WHERE clause, etc.) is to set it using
+        :meth:`.Select.select_from`::
+
+            >>> s1 = select([table1.c.a, table2.c.b]).\\
+            ...         select_from(table1.join(table2,
+            ...                 table1.c.a==table2.c.a))
+            >>> s2 = s1.with_only_columns([table2.c.b])
+            >>> print s2
+            SELECT t2.b FROM t1 JOIN t2 ON t1.a=t2.a
+
+        Care should also be taken to use the correct
+        set of column objects passed to :meth:`.Select.with_only_columns`.
+        Since the method is essentially equivalent to calling the
+        :func:`.select` construct in the first place with the given
+        columns, the columns passed to :meth:`.Select.with_only_columns`
+        should usually be a subset of those which were passed
+        to the :func:`.select` construct, not those which are available
+        from the ``.c`` collection of that :func:`.select`.  That
+        is::
+
+            s = select([table1.c.a, table1.c.b]).select_from(table1)
+            s = s.with_only_columns([table1.c.b])
+
+        and **not**::
+
+            # usually incorrect
+            s = s.with_only_columns([s.c.b])
+
+        The latter would produce the SQL::
+
+            SELECT b
+            FROM (SELECT t1.a AS a, t1.b AS b
+            FROM t1), t1
+
+        Since the :func:`.select` construct is essentially being
+        asked to select both from ``table1`` as well as itself.

+    that assumes input and output as Python ``unicode`` data,
+    and in that regard is equivalent to the usage of the
+    ``convert_unicode`` flag with the :class:`.String` type.
+    However, unlike plain :class:`.String`, it also implies an
+    underlying column type that is explicitly supporting of non-ASCII
+    data, such as ``NVARCHAR`` on Oracle and SQL Server.
+    This can impact the output of ``CREATE TABLE`` statements
+    and ``CAST`` functions at the dialect level, and can
+    also affect the handling of bound parameters in some
+    specific DBAPI scenarios.
+
+    The encoding used by the :class:`.Unicode` type is usually
+    determined by the DBAPI itself; most modern DBAPIs
+    feature support for Python ``unicode`` objects as bound
+    values and result set values, and the encoding should
+    be configured as detailed in the notes for the target
+    DBAPI in the :ref:`dialect_toplevel` section.
+
+    For those DBAPIs which do not support, or are not configured
+    to accommodate Python ``unicode`` objects
+    directly, SQLAlchemy does the encoding and decoding
+    outside of the DBAPI.   The encoding in this scenario
+    is determined by the ``encoding`` flag passed to
+    :func:`.create_engine`.
+
+    When using the :class:`.Unicode` type, it is only appropriate
+    to pass Python ``unicode`` objects, and not plain ``str``.
+    If a plain ``str`` is passed under Python 2, a warning
+    is emitted.  If you notice your application emitting these warnings but
+    you're not sure of the source of them, the Python
+    ``warnings`` filter, documented at
+    http://docs.python.org/library/warnings.html,
+    can be used to turn these warnings into exceptions
+    which will illustrate a stack trace::
+
+      import warnings
+      warnings.simplefilter('error')
+
+    For an application that wishes to pass plain bytestrings
+    and Python ``unicode`` objects to the ``Unicode`` type
+    equally, the bytestrings must first be decoded into
+    unicode.  The recipe at :ref:`coerce_to_unicode` illustrates

+
+    The class-level "impl" attribute is required, and can reference any
+    TypeEngine class.  Alternatively, the load_dialect_impl() method
+    can be used to provide different type classes based on the dialect
+    given; in this case, the "impl" variable can reference
+    ``TypeEngine`` as a placeholder.
+
+    Types that receive a Python type that isn't similar to the ultimate type
+    used may want to define the :meth:`TypeDecorator.coerce_compared_value`
+    method. This is used to give the expression system a hint when coercing
+    Python objects into bind parameters within expressions. Consider this
+    expression::
+
+        mytable.c.somecol + datetime.date(2009, 5, 15)
+
+    Above, if "somecol" is an ``Integer`` variant, it makes sense that
+    we're doing date arithmetic, where above is usually interpreted
+    by databases as adding a number of days to the given date.
+    The expression system does the right thing by not attempting to
+    coerce the "date()" value into an integer-oriented bind parameter.
+
+    However, in the case of ``TypeDecorator``, we are usually changing an
+    incoming Python type to something new - ``TypeDecorator`` by default will
+    "coerce" the non-typed side to be the same type as itself. Such as below,
+    we define an "epoch" type that stores a date value as an integer::
+
+        class MyEpochType(types.TypeDecorator):
+            impl = types.Integer
+
+            epoch = datetime.date(1970, 1, 1)
+
+            def process_bind_param(self, value, dialect):
+                return (value - self.epoch).days
+
+            def process_result_value(self, value, dialect):
+                return self.epoch + timedelta(days=value)
+
+    Our expression of ``somecol + date`` with the above type will coerce the
+    "date" on the right side to also be treated as ``MyEpochType``.
+
+    This behavior can be overridden via the
+    :meth:`~TypeDecorator.coerce_compared_value` method, which returns a type
+    that should be used for the value of the expression. Below we set it such
+    that an integer value will be treated as an ``Integer``, and any other
+    value is assumed to be a date and will be treated as a ``MyEpochType``::

+"""Visitor/traversal interface and library functions.
+
+SQLAlchemy schema and expression constructs rely on a Python-centric
+version of the classic "visitor" pattern as the primary way in which
+they apply functionality.  The most common use of this pattern
+is statement compilation, where individual expression classes match
+up to rendering methods that produce a string result.   Beyond this,
+the visitor system is also used to inspect expressions for various
+information and patterns, as well as for usage in
+some kinds of expression transformation.  Other kinds of transformation
+use a non-visitor traversal system.
+
+For many examples of how the visit system is used, see the
+sqlalchemy.sql.util and the sqlalchemy.sql.compiler modules.
+For an introduction to clause adaption, see
+http://techspot.zzzeek.org/2008/01/23/expression-transformations/

+Nose test runner module.
+
+This script is a front-end to "nosetests" which
+installs SQLAlchemy's testing plugin into the local environment.
+
+The script is intended to be used by third-party dialects and extensions
+that run within SQLAlchemy's testing framework.    The runner can
+be invoked via::
+
+    python -m sqlalchemy.testing.runner
+
+The script is then essentially the same as the "nosetests" script, including
+all of the usual Nose options.   The test environment requires that a
+setup.cfg is locally present including various required options.
+
+Note that when using this runner, Nose's "coverage" plugin will not be
+able to provide coverage for SQLAlchemy itself, since SQLAlchemy is
+imported into sys.modules before coverage is started.   The special
+script sqla_nose.py is provided as a top-level script which loads the
+plugin in a special (somewhat hacky) way so that coverage against
+SQLAlchemy itself is possible.

-Metadata-Version: 1.1
-Name: backports.ssl-match-hostname
-Version: 3.4.0.2
-Summary: The ssl.match_hostname() function from Python 3.4
-Home-page: http://bitbucket.org/brandon/backports.ssl_match_hostname
-Author: Brandon Craig Rhodes
-Author-email: brandon@rhodesmill.org
-License: UNKNOWN
-Description: 
-        The Secure Sockets layer is only actually *secure*
-        if you check the hostname in the certificate returned
-        by the server to which you are connecting,
-        and verify that it matches to hostname
-        that you are trying to reach.
-        
-        But the matching logic, defined in `RFC2818`_,
-        can be a bit tricky to implement on your own.
-        So the ``ssl`` package in the Standard Library of Python 3.2
-        and greater now includes a ``match_hostname()`` function
-        for performing this check instead of requiring every application
-        to implement the check separately.
-        
-        This backport brings ``match_hostname()`` to users
-        of earlier versions of Python.
-        Simply make this distribution a dependency of your package,
-        and then use it like this::
-        
-            from backports.ssl_match_hostname import match_hostname, CertificateError
-            ...
-            sslsock = ssl.wrap_socket(sock, ssl_version=ssl.PROTOCOL_SSLv3,
-                                      cert_reqs=ssl.CERT_REQUIRED, ca_certs=...)
-            try:
-                match_hostname(sslsock.getpeercert(), hostname)
-            except CertificateError, ce:
-                ...
-        
-        Note that the ``ssl`` module is only included in the Standard Library
-        for Python 2.6 and later;
-        users of Python 2.5 or earlier versions
-        will also need to install the ``ssl`` distribution
-        from the Python Package Index to use code like that shown above.
-        
-        Brandon Craig Rhodes is merely the packager of this distribution;
-        the actual code inside comes verbatim from Python 3.4.
-        
-        History
-        -------
-        * This function was introduced in python-3.2
-        * It was updated for python-3.4a1 for a CVE 
-          (backports-ssl_match_hostname-3.4.0.1)
-        * It was updated from RFC2818 to RFC 6125 compliance in order to fix another
-          security flaw for python-3.3.3 and python-3.4a5

-    (URL, pathname to local or network file, or actual data as a string)
-    and deal with it in a uniform manner.  Returned object is guaranteed
-    to have all the basic stdio read methods (read, readline, readlines).
-    Just .close() the object when you're done with it.
-
-    If the etag argument is supplied, it will be used as the value of an
-    If-None-Match request header.
-
-    If the modified argument is supplied, it can be a tuple of 9 integers
-    (as returned by gmtime() in the standard Python time module) or a date
-    string in any format supported by feedparser. Regardless, it MUST
-    be in GMT (Greenwich Mean Time). It will be reformatted into an
-    RFC 1123-compliant date and used as the value of an If-Modified-Since
-    request header.
-
-    If the agent argument is supplied, it will be used as the value of a
-    User-Agent request header.
-
-    If the referrer argument is supplied, it will be used as the value of a
-    Referer[sic] request header.
-
-    If handlers is supplied, it is a list of handlers used to build a
-    urllib2 opener.
-
-    if request_headers is supplied it is a dictionary of HTTP request headers

-Package resource API
---------------------
-
-A resource is a logical file contained within a package, or a logical
-subdirectory thereof.  The package resource API expects resource names
-to have their path parts separated with ``/``, *not* whatever the local
-path separator is.  Do not use os.path operations to manipulate resource
-names being passed into the API.
-
-The package resource API is designed to work with normal filesystem packages,
-.egg files, and unpacked .egg files.  It can also work in a limited way with
-.zip files and with custom PEP 302 loaders that support the ``get_data()``
-method.

-
-    This is a rough cross between distutils' StrictVersion and LooseVersion;
-    if you give it versions that would work with StrictVersion, then it behaves
-    the same; otherwise it acts like a slightly-smarter LooseVersion. It is
-    *possible* to create pathological version coding schemes that will fool
-    this parser, but they should be very rare in practice.
-
-    The returned value will be a tuple of strings.  Numeric portions of the
-    version are padded to 8 digits so they will compare numerically, but
-    without relying on how numbers compare relative to strings.  Dots are
-    dropped, but dashes are retained.  Trailing zeros between alpha segments
-    or dashes are suppressed, so that e.g. "2.4.0" is considered the same as
-    "2.4". Alphanumeric parts are lower-cased.
-
-    The algorithm assumes that strings like "-" and any alpha string that
-    alphabetically follows "final"  represents a "patch level".  So, "2.4-1"
-    is assumed to be a branch or patch of "2.4", and therefore "2.4.1" is
-    considered newer than "2.4-1", which in turn is newer than "2.4".
-
-    Strings like "a", "b", "c", "alpha", "beta", "candidate" and so on (that
-    come before "final" alphabetically) are assumed to be pre-release versions,
-    so that the version "2.4" is considered newer than "2.4a1".
-
-    Finally, to handle miscellaneous cases, the strings "pre", "preview", and
-    "rc" are treated as if they were "c", i.e. as though they were release
-    candidates, and therefore are not as new as a version string that does not
-    contain them, and "dev" is replaced with an '@' so that it sorts lower than
-    than any other pre-release tag.

-Summary: PDF toolkit

-Description: 
-        A Pure-Python library built as a PDF toolkit.  It is capable of:
-            
-        - extracting document information (title, author, ...),
-        - splitting documents page by page,
-        - merging documents page by page,
-        - cropping pages,
-        - merging multiple pages into a single page,
-        - encrypting and decrypting PDF files.
-        
-        By being Pure-Python, it should run on any Python platform without any
-        dependencies on external libraries.  It can also work entirely on StringIO
-        objects rather than file streams, allowing for PDF manipulation in memory.
-        It is therefore a useful tool for websites that manage or manipulate PDFs.
-

-# What is the PDFX namespace, you might ask?  I might ask that too.  It's
-# a completely undocumented namespace used to place "custom metadata"
-# properties, which are arbitrary metadata properties with no semantic or
-# documented meaning.  Elements in the namespace are key/value-style storage,
-# where the element name is the key and the content is the value.  The keys
-# are transformed into valid XML identifiers by substituting an invalid
-# identifier character with \u2182 followed by the unicode hex ID of the
-# original character.  A key like "my car" is therefore "my\u21820020car".
-#
-# \u2182, in case you're wondering, is the unicode character
-# \u{ROMAN NUMERAL TEN THOUSAND}, a straightforward and obvious choice for
-# escaping characters.
-#
-# Intentional users of the pdfx namespace should be shot on sight.  A
-# custom data schema and sensical XML elements could be used instead, as is
-# suggested by Adobe's own documentation on XMP (under "Extensibility of
-# Schemas").
-#
-# Information presented here on the /pdfx/ schema is a result of limited
-# reverse engineering, and does not constitute a full specification.

-===============================
-Installing and Using Setuptools
-===============================
-
-.. contents:: **Table of Contents**
-
-
--------------------------
-Installation Instructions
--------------------------
-
-The recommended way to bootstrap setuptools on any system is to download
-`ez_setup.py`_ and run it using the target Python environment. Different
-operating systems have different recommended techniques to accomplish this
-basic routine, so below are some examples to get you started.
-
-Setuptools requires Python 2.6 or later. To install setuptools
-on Python 2.4 or Python 2.5, use the `bootstrap script for Setuptools 1.x
-<https://bitbucket.org/pypa/setuptools/raw/bootstrap-py24/ez_setup.py>`_.
-
-The link provided to ez_setup.py is a bookmark to bootstrap script for the
-latest known stable release.
-
-.. _ez_setup.py: https://bootstrap.pypa.io/ez_setup.py
-
-Windows 8 (Powershell)
-======================
-
-For best results, uninstall previous versions FIRST (see `Uninstalling`_).
-
-Using Windows 8 or later, it's possible to install with one simple Powershell
-command. Start up Powershell and paste this command::
-
-    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python -
-
-You must start the Powershell with Administrative privileges or you may choose
-to install a user-local installation::
-
-    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python - --user
-
-If you have Python 3.3 or later, you can use the ``py`` command to install to
-different Python versions. For example, to install to Python 3.3 if you have
-Python 2.7 installed::
-
-    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | py -3 -
-
-The recommended way to install setuptools on Windows is to download
-`ez_setup.py`_ and run it. The script will download the appropriate .egg
-file and install it for you.
-
-Once installation is complete, you will find an ``easy_install`` program in
-your Python ``Scripts`` subdirectory.  For simple invocation and best results,
-add this directory to your ``PATH`` environment variable, if it is not already
-present. If you did a user-local install, the ``Scripts`` subdirectory is
-``$env:APPDATA\Python\Scripts``.
-
-
-Windows 7 (or graphical install)
-================================
-
-For Windows 7 and earlier, download `ez_setup.py`_ using your favorite web
-browser or other technique and "run" that file.
-
-
-Unix (wget)
-===========
-
-Most Linux distributions come with wget.
-
-Download `ez_setup.py`_ and run it using the target Python version. The script
-will download the appropriate version and install it for you::
-
-    > wget https://bootstrap.pypa.io/ez_setup.py -O - | python
-
-Note that you will may need to invoke the command with superuser privileges to
-install to the system Python::
-
-    > wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
-
-Alternatively, Setuptools may be installed to a user-local path::
-
-    > wget https://bootstrap.pypa.io/ez_setup.py -O - | python - --user
-
-Unix including Mac OS X (curl)
-==============================
-
-If your system has curl installed, follow the ``wget`` instructions but
-replace ``wget`` with ``curl`` and ``-O`` with ``-o``. For example::
-
-    > curl https://bootstrap.pypa.io/ez_setup.py -o - | python
-
-
-Advanced Installation
-=====================
-
-For more advanced installation options, such as installing to custom
-locations or prefixes, download and extract the source
-tarball from `Setuptools on PyPI <https://pypi.python.org/pypi/setuptools>`_
-and run setup.py with any supported distutils and Setuptools options.
-For example::
-
-    setuptools-x.x$ python setup.py install --prefix=/opt/setuptools
-
-Use ``--help`` to get a full options list, but we recommend consulting
-the `EasyInstall manual`_ for detailed instructions, especially `the section
-on custom installation locations`_.
-
-.. _EasyInstall manual: https://pythonhosted.org/setuptools/EasyInstall
-.. _the section on custom installation locations: https://pythonhosted.org/setuptools/EasyInstall#custom-installation-locations
-
-
-Downloads
-=========
-
-All setuptools downloads can be found at `the project's home page in the Python
-Package Index`_.  Scroll to the very bottom of the page to find the links.
-
-.. _the project's home page in the Python Package Index: https://pypi.python.org/pypi/setuptools
-
-In addition to the PyPI downloads, the development version of ``setuptools``
-is available from the `Bitbucket repo`_, and in-development versions of the
-`0.6 branch`_ are available as well.
-
-.. _Bitbucket repo: https://bitbucket.org/pypa/setuptools/get/default.tar.gz#egg=setuptools-dev
-.. _0.6 branch: http://svn.python.org/projects/sandbox/branches/setuptools-0.6/#egg=setuptools-dev06
-
-Uninstalling
-============
-
-On Windows, if Setuptools was installed using an ``.exe`` or ``.msi``
-installer, simply use the uninstall feature of "Add/Remove Programs" in the
-Control Panel.
-
-Otherwise, to uninstall Setuptools or Distribute, regardless of the Python
-version, delete all ``setuptools*`` and ``distribute*`` files and
-directories from your system's ``site-packages`` directory
-(and any other ``sys.path`` directories) FIRST.
-
-If you are upgrading or otherwise plan to re-install Setuptools or Distribute,
-nothing further needs to be done. If you want to completely remove Setuptools,
-you may also want to remove the 'easy_install' and 'easy_install-x.x' scripts
-and associated executables installed to the Python scripts directory.
-
---------------------------------
-Using Setuptools and EasyInstall
---------------------------------
-
-Here are some of the available manuals, tutorials, and other resources for
-learning about Setuptools, Python Eggs, and EasyInstall:
-
-* `The EasyInstall user's guide and reference manual`_
-* `The setuptools Developer's Guide`_
-* `The pkg_resources API reference`_
-* `Package Compatibility Notes`_ (user-maintained)
-* `The Internal Structure of Python Eggs`_
-
-Questions, comments, and bug reports should be directed to the `distutils-sig
-mailing list`_.  If you have written (or know of) any tutorials, documentation,
-plug-ins, or other resources for setuptools users, please let us know about
-them there, so this reference list can be updated.  If you have working,
-*tested* patches to correct problems or add features, you may submit them to
-the `setuptools bug tracker`_.

-Credits
--------
-
-* The original design for the ``.egg`` format and the ``pkg_resources`` API was
-  co-created by Phillip Eby and Bob Ippolito.  Bob also implemented the first
-  version of ``pkg_resources``, and supplied the OS X operating system version
-  compatibility algorithm.
-
-* Ian Bicking implemented many early "creature comfort" features of
-  easy_install, including support for downloading via Sourceforge and
-  Subversion repositories.  Ian's comments on the Web-SIG about WSGI
-  application deployment also inspired the concept of "entry points" in eggs,
-  and he has given talks at PyCon and elsewhere to inform and educate the
-  community about eggs and setuptools.
-
-* Jim Fulton contributed time and effort to build automated tests of various
-  aspects of ``easy_install``, and supplied the doctests for the command-line
-  ``.exe`` wrappers on Windows.
-
-* Phillip J. Eby is the seminal author of setuptools, and
-  first proposed the idea of an importable binary distribution format for
-  Python application plug-ins.
-
-* Significant parts of the implementation of setuptools were funded by the Open
-  Source Applications Foundation, to provide a plug-in infrastructure for the
-  Chandler PIM application.  In addition, many OSAF staffers (such as Mike
-  "Code Bear" Taylor) contributed their time and stress as guinea pigs for the
-  use of eggs and setuptools, even before eggs were "cool".  (Thanks, guys!)
-
-* Tarek Ziadé is the principal author of the Distribute fork, which
-  re-invigorated the community on the project, encouraged renewed innovation,
-  and addressed many defects.
-
-* Since the merge with Distribute, Jason R. Coombs is the
-  maintainer of setuptools.  The project is maintained in coordination with
-  the Python Packaging Authority (PyPA) and the larger Python community.

-CHANGES
-=======
-
----
-5.7
----
-
-* `Issue #240 <https://bitbucket.org/pypa/setuptools/issue/240>`_: Based on real-world performance measures against 5.4, zip
-  manifests are now cached in all circumstances. The
-  ``PKG_RESOURCES_CACHE_ZIP_MANIFESTS`` environment variable is no longer
-  relevant. The observed "memory increase" referenced in the 5.4 release
-  notes and detailed in `Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154>`_ was likely not an increase over the status
-  quo, but rather only an increase over not storing the zip info at all.
-
----
-5.6
----
-
-* `Issue #242 <https://bitbucket.org/pypa/setuptools/issue/242>`_: Use absolute imports in svn_utils to avoid issues if the
-  installing package adds an xml module to the path.
-
------
-5.5.1
------
-
-* `Issue #239 <https://bitbucket.org/pypa/setuptools/issue/239>`_: Fix typo in 5.5 such that fix did not take.
-
----
-5.5
----
-
-* `Issue #239 <https://bitbucket.org/pypa/setuptools/issue/239>`_: Setuptools now includes the setup_requires directive on
-  Distribution objects and validates the syntax just like install_requires
-  and tests_require directives.
-
------
-5.4.2
------
-
-* `Issue #236 <https://bitbucket.org/pypa/setuptools/issue/236>`_: Corrected regression in execfile implementation for Python 2.6.
-
------
-5.4.1
------
-
-* `Python #7776 <http://bugs.python.org/issue7776>`_: (ssl_support) Correct usage of host for validation when
-  tunneling for HTTPS.
-
----
-5.4
----
-
-* `Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154>`_: ``pkg_resources`` will now cache the zip manifests rather than
-  re-processing the same file from disk multiple times, but only if the
-  environment variable ``PKG_RESOURCES_CACHE_ZIP_MANIFESTS`` is set. Clients
-  that package many modules in the same zip file will see some improvement
-  in startup time by enabling this feature. This feature is not enabled by
-  default because it causes a substantial increase in memory usage.
-
----
-5.3
----
-
-* `Issue #185 <https://bitbucket.org/pypa/setuptools/issue/185>`_: Make svn tagging work on the new style SVN metadata.

-* During install_egg_info, the generated lines for namespace package .pth
-  files are now processed even during a dry run.
-
----
-5.1
----
-
-* `Issue #202 <https://bitbucket.org/pypa/setuptools/issue/202>`_: Implemented more robust cache invalidation for the ZipImporter,
-  building on the work in `Issue #168 <https://bitbucket.org/pypa/setuptools/issue/168>`_. Special thanks to Jurko Gospodnetic and
-  PJE.
-
------
-5.0.2

-  unchanged.
-
----
-3.3
----

-
----
-3.2
----
-

-
------
-3.0.1
------
-
-* `Issue #157 <https://bitbucket.org/pypa/setuptools/issue/157>`_: Restore support for Python 2.6 in bootstrap script where
-  ``zipfile.ZipFile`` does not yet have support for context managers.
-
----
-3.0
----
-
-* `Issue #125 <https://bitbucket.org/pypa/setuptools/issue/125>`_: Prevent Subversion support from creating a ~/.subversion
-  directory just for checking the presence of a Subversion repository.
-* `Issue #12 <https://bitbucket.org/pypa/setuptools/issue/12>`_: Namespace packages are now imported lazily.  That is, the mere
-  declaration of a namespace package in an egg on ``sys.path`` no longer
-  causes it to be imported when ``pkg_resources`` is imported.  Note that this
-  change means that all of a namespace package's ``__init__.py`` files must
-  include a ``declare_namespace()`` call in order to ensure that they will be
-  handled properly at runtime.  In 2.x it was possible to get away without
-  including the declaration, but only at the cost of forcing namespace
-  packages to be imported early, which 3.0 no longer does.
-* `Issue #148 <https://bitbucket.org/pypa/setuptools/issue/148>`_: When building (bdist_egg), setuptools no longer adds
-  ``__init__.py`` files to namespace packages. Any packages that rely on this
-  behavior will need to create ``__init__.py`` files and include the
-  ``declare_namespace()``.
-* `Issue #7 <https://bitbucket.org/pypa/setuptools/issue/7>`_: Setuptools itself is now distributed as a zip archive in addition to
-  tar archive. ez_setup.py now uses zip archive. This approach avoids the potential
-  security vulnerabilities presented by use of tar archives in ez_setup.py.
-  It also leverages the security features added to ZipFile.extract in Python 2.7.4.
-* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Removed deprecated Features functionality.
-* `Pull Request #28 <https://bitbucket.org/pypa/setuptools/pull-request/28>`_: Remove backport of ``_bytecode_filenames`` which is
-  available in Python 2.6 and later, but also has better compatibility with
-  Python 3 environments.
-* `Issue #156 <https://bitbucket.org/pypa/setuptools/issue/156>`_: Fix spelling of __PYVENV_LAUNCHER__ variable.
-
----
-2.2
----
-
-* `Issue #141 <https://bitbucket.org/pypa/setuptools/issue/141>`_: Restored fix for allowing setup_requires dependencies to

-
-* `Issue #105 <https://bitbucket.org/pypa/setuptools/issue/105>`_ and `Issue #113 <https://bitbucket.org/pypa/setuptools/issue/113>`_: Establish a more robust technique for
-  determining the terminal encoding::
-
-    1. Try ``getpreferredencoding``
-    2. If that returns US_ASCII or None, try the encoding from
-       ``getdefaultlocale``. If that encoding was a "fallback" because Python
-       could not figure it out from the environment or OS, encoding remains
-       unresolved.
-    3. If the encoding is resolved, then make sure Python actually implements
-       the encoding.
-    4. On the event of an error or unknown codec, revert to fallbacks
-       (UTF-8 on Darwin, ASCII on everything else).
-    5. On the encoding is 'mac-roman' on Darwin, use UTF-8 as 'mac-roman' was
-       a bug on older Python releases.
-
-    On a side note, it would seem that the encoding only matters for when SVN
-    does not yet support ``--xml`` and when getting repository and svn version
-    numbers. The ``--xml`` technique should yield UTF-8 according to some
-    messages on the SVN mailing lists. So if the version numbers are always
-    7-bit ASCII clean, it may be best to only support the file parsing methods
-    for legacy SVN releases and support for SVN without the subprocess command
-    would simple go away as support for the older SVNs does.

-  reported in `Issue #108 <https://bitbucket.org/pypa/setuptools/issue/108>`_, as of Pip 1.4, scripts aren't installed properly
-  from wheels. Therefore, if using Pip to install setuptools from a wheel,
-  the ``easy_install`` command will not be available.
-* Setuptools "natural" launcher support, introduced in 1.0, is now officially
-  supported.

-* `Issue #60 <https://bitbucket.org/pypa/setuptools/issue/60>`_: On Windows, Setuptools supports deferring to another launcher,
-  such as Vinay Sajip's `pylauncher <https://bitbucket.org/pypa/pylauncher>`_
-  (included with Python 3.3) to launch console and GUI scripts and not install
-  its own launcher executables. This experimental functionality is currently
-  only enabled if  the ``SETUPTOOLS_LAUNCHER`` environment variable is set to
-  "natural". In the future, this behavior may become default, but only after
-  it has matured and seen substantial adoption. The ``SETUPTOOLS_LAUNCHER``
-  also accepts "executable" to force the default behavior of creating launcher
-  executables.
-* `Issue #63 <https://bitbucket.org/pypa/setuptools/issue/63>`_: Bootstrap script (ez_setup.py) now prefers Powershell, curl, or
-  wget for retrieving the Setuptools tarball for improved security of the
-  install. The script will still fall back to a simple ``urlopen`` on
-  platforms that do not have these tools.
-* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Deprecated the ``Features`` functionality.

-  connection.

-Backward-Incompatible Changes
-=============================
-
-This release includes a couple of backward-incompatible changes, but most if
-not all users will find 1.0 a drop-in replacement for 0.9.
-
-* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: Normalized API of environment marker support. Specifically,
-  removed line number and filename from SyntaxErrors when returned from
-  `pkg_resources.invalid_marker`. Any clients depending on the specific
-  string representation of exceptions returned by that function may need to
-  be updated to account for this change.
-* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: SyntaxErrors generated by `pkg_resources.invalid_marker` are
-  normalized for cross-implementation consistency.
-* Removed ``--ignore-conflicts-at-my-risk`` and ``--delete-conflicting``
-  options to easy_install. These options have been deprecated since 0.6a11.

-0.7
----
-
-* Merged Setuptools and Distribute. See docs/merge.txt for details.
-
-Added several features that were slated for setuptools 0.6c12:
-
-* Index URL now defaults to HTTPS.
-* Added experimental environment marker support. Now clients may designate a
-  PEP-426 environment marker for "extra" dependencies. Setuptools uses this
-  feature in ``setup.py`` for optional SSL and certificate validation support
-  on older platforms. Based on Distutils-SIG discussions, the syntax is
-  somewhat tentative. There should probably be a PEP with a firmer spec before
-  the feature should be considered suitable for use.
-* Added support for SSL certificate validation when installing packages from
-  an HTTPS service.
-
------
-0.7b4

-
-------
-0.6.49
-------
-
-* Move warning check in ``get_cache_path`` to follow the directory creation
-  to avoid errors when the cache path does not yet exist. Fixes the error

-------
-0.6.48
-------

-* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Issue a warning if the PYTHON_EGG_CACHE or otherwise
-  customized egg cache location specifies a directory that's group- or
-  world-writable.
-
-------
-0.6.45
-------
-

-------
-0.6.42
-------
-
-* External links finder no longer yields duplicate links.
-* `Distribute #337 <https://bitbucket.org/tarek/distribute/issue/337>`_: Moved site.py to setuptools/site-patch.py (graft of very old
-  patch from setuptools trunk which inspired PR `#31 <https://bitbucket.org/pypa/setuptools/issue/31>`_).
-
-------
-0.6.41
-------
-
-* `Distribute #27 <https://bitbucket.org/tarek/distribute/issue/27>`_: Use public api for loading resources from zip files rather than
-  the private method `_zip_directory_cache`.
-* Added a new function ``easy_install.get_win_launcher`` which may be used by
-  third-party libraries such as buildout to get a suitable script launcher.
-
-------
-0.6.40
-------
-
-* `Distribute #376 <https://bitbucket.org/tarek/distribute/issue/376>`_: brought back cli.exe and gui.exe that were deleted in the
-  previous release.
-
-------
-0.6.39
-------
-
-* Add support for console launchers on ARM platforms.
-* Fix possible issue in GUI launchers where the subsystem was not supplied to
-  the linker.
-* Launcher build script now refactored for robustness.
-* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Resources extracted from a zip egg to the file system now also
-  check the contents of the file against the zip contents during each
-  invocation of get_resource_filename.

-------
-0.6.38
-------
-
-* `Distribute #371 <https://bitbucket.org/tarek/distribute/issue/371>`_: The launcher manifest file is now installed properly.
-
-------
-0.6.37
-------
-
-* `Distribute #143 <https://bitbucket.org/tarek/distribute/issue/143>`_: Launcher scripts, including easy_install itself, are now
-  accompanied by a manifest on 32-bit Windows environments to avoid the
-  Installer Detection Technology and thus undesirable UAC elevation described
-  in `this Microsoft article
-  <http://technet.microsoft.com/en-us/library/cc709628%28WS.10%29.aspx>`_.
-
-------
-0.6.36
-------
-
-* `Pull Request #35 <https://bitbucket.org/pypa/setuptools/pull-request/35>`_: In `Buildout #64 <https://github.com/buildout/buildout/issues/64>`_, it was reported that
-  under Python 3, installation of distutils scripts could attempt to copy
-  the ``__pycache__`` directory as a file, causing an error, apparently only
-  under Windows. Easy_install now skips all directories when processing
-  metadata scripts.
-
-------
-0.6.35
-------
-
-
-Note this release is backward-incompatible with distribute 0.6.23-0.6.34 in

-------
-0.6.31
-------
-
-* `Distribute #303 <https://bitbucket.org/tarek/distribute/issue/303>`_: Make sure the manifest only ever contains UTF-8 in Python 3.

-  Jython.
-* Work around `Jython #1980 <http://bugs.jython.org/issue1980>`_ and `Jython #1981 <http://bugs.jython.org/issue1981>`_.
-* `Distribute #334 <https://bitbucket.org/tarek/distribute/issue/334>`_: Provide workaround for packages that reference `sys.__stdout__`
-  such as numpy does. This change should address
-  `virtualenv `#359 <https://bitbucket.org/pypa/setuptools/issue/359>`_ <https://github.com/pypa/virtualenv/issues/359>`_ as long
-  as the system encoding is UTF-8 or the IO encoding is specified in the
-  environment, i.e.::
-
-     PYTHONIOENCODING=utf8 pip install numpy
-
-* Fix for encoding issue when installing from Windows executable on Python 3.
-* `Distribute #323 <https://bitbucket.org/tarek/distribute/issue/323>`_: Allow `setup_requires` requirements to supercede installed
-  requirements. Added some new keyword arguments to existing pkg_resources
-  methods. Also had to updated how __path__ is handled for namespace packages
-  to ensure that when a new egg distribution containing a namespace package is
-  placed on sys.path, the entries in __path__ are found in the same order they
-  would have been in had that egg been on the path when pkg_resources was
-  first imported.
-
-------
-0.6.30
-------
-
-* `Distribute #328 <https://bitbucket.org/tarek/distribute/issue/328>`_: Clean up temporary directories in distribute_setup.py.

-
-------
-0.6.29
-------
-
-* `Pull Request #14 <https://bitbucket.org/pypa/setuptools/pull-request/14>`_: Honor file permissions in zip files.
-* `Distribute #327 <https://bitbucket.org/tarek/distribute/issue/327>`_: Merged pull request `#24 <https://bitbucket.org/pypa/setuptools/issue/24>`_ to fix a dependency problem with pip.
-* Merged pull request `#23 <https://bitbucket.org/pypa/setuptools/issue/23>`_ to fix https://github.com/pypa/virtualenv/issues/301.
-* If Sphinx is installed, the `upload_docs` command now runs `build_sphinx`
-  to produce uploadable documentation.
-* `Distribute #326 <https://bitbucket.org/tarek/distribute/issue/326>`_: `upload_docs` provided mangled auth credentials under Python 3.
-* `Distribute #320 <https://bitbucket.org/tarek/distribute/issue/320>`_: Fix check for "createable" in distribute_setup.py.
-* `Distribute #305 <https://bitbucket.org/tarek/distribute/issue/305>`_: Remove a warning that was triggered during normal operations.
-* `Distribute #311 <https://bitbucket.org/tarek/distribute/issue/311>`_: Print metadata in UTF-8 independent of platform.
-* `Distribute #303 <https://bitbucket.org/tarek/distribute/issue/303>`_: Read manifest file with UTF-8 encoding under Python 3.

-* `Distribute #283 <https://bitbucket.org/tarek/distribute/issue/283>`_: Reenable scanning of `*.pyc` / `*.pyo` files on Python 3.3.
-* `Distribute #299 <https://bitbucket.org/tarek/distribute/issue/299>`_: The develop command didn't work on Python 3, when using 2to3,
-  as the egg link would go to the Python 2 source. Linking to the 2to3'd code
-  in build/lib makes it work, although you will have to rebuild the module
-  before testing it.
-* `Distribute #306 <https://bitbucket.org/tarek/distribute/issue/306>`_: Even if 2to3 is used, we build in-place under Python 2.
-* `Distribute #307 <https://bitbucket.org/tarek/distribute/issue/307>`_: Prints the full path when .svn/entries is broken.

------
-0.6c9
------
-
- * Fixed a missing files problem when using Windows source distributions on
-   non-Windows platforms, due to distutils not handling manifest file line
-   endings correctly.
-
- * Updated Pyrex support to work with Pyrex 0.9.6 and higher.
-
- * Minor changes for Jython compatibility, including skipping tests that can't
-   work on Jython.
-
- * Fixed not installing eggs in ``install_requires`` if they were also used for
-   ``setup_requires`` or ``tests_require``.
-
- * Fixed not fetching eggs in ``install_requires`` when running tests.
-
- * Allow ``ez_setup.use_setuptools()`` to upgrade existing setuptools
-   installations when called from a standalone ``setup.py``.
-
- * Added a warning if a namespace package is declared, but its parent package
-   is not also declared as a namespace.
-
- * Support Subversion 1.5
-
- * Removed use of deprecated ``md5`` module if ``hashlib`` is available
-
- * Fixed ``bdist_wininst upload`` trying to upload the ``.exe`` twice
-
- * Fixed ``bdist_egg`` putting a ``native_libs.txt`` in the source package's
-   ``.egg-info``, when it should only be in the built egg's ``EGG-INFO``.
-
- * Ensure that _full_name is set on all shared libs before extensions are
-   checked for shared lib usage.  (Fixes a bug in the experimental shared
-   library build support.)
-
- * Fix to allow unpacked eggs containing native libraries to fail more
-   gracefully under Google App Engine (with an ``ImportError`` loading the
-   C-based module, instead of getting a ``NameError``).
-
------
-0.6c7
------
-
- * Fixed ``distutils.filelist.findall()`` crashing on broken symlinks, and
-   ``egg_info`` command failing on new, uncommitted SVN directories.
-
- * Fix import problems with nested namespace packages installed via
-   ``--root`` or ``--single-version-externally-managed``, due to the
-   parent package not having the child package as an attribute.
-
------
-0.6c6
------
-
- * Added ``--egg-path`` option to ``develop`` command, allowing you to force
-   ``.egg-link`` files to use relative paths (allowing them to be shared across
-   platforms on a networked drive).
-
- * Fix not building binary RPMs correctly.
-
- * Fix "eggsecutables" (such as setuptools' own egg) only being runnable with
-   bash-compatible shells.
-
- * Fix ``#!`` parsing problems in Windows ``.exe`` script wrappers, when there
-   was whitespace inside a quoted argument or at the end of the ``#!`` line
-   (a regression introduced in 0.6c4).
-
- * Fix ``test`` command possibly failing if an older version of the project
-   being tested was installed on ``sys.path`` ahead of the test source
-   directory.
-
- * Fix ``find_packages()`` treating ``ez_setup`` and directories with ``.`` in
-   their names as packages.
-
------
-0.6c5
------
-
- * Fix uploaded ``bdist_rpm`` packages being described as ``bdist_egg``
-   packages under Python versions less than 2.5.
-
- * Fix uploaded ``bdist_wininst`` packages being described as suitable for
-   "any" version by Python 2.5, even if a ``--target-version`` was specified.
-
------
-0.6c4
------
-
- * Overhauled Windows script wrapping to support ``bdist_wininst`` better.
-   Scripts installed with ``bdist_wininst`` will always use ``#!python.exe`` or
-   ``#!pythonw.exe`` as the executable name (even when built on non-Windows
-   platforms!), and the wrappers will look for the executable in the script's
-   parent directory (which should find the right version of Python).
-
- * Fix ``upload`` command not uploading files built by ``bdist_rpm`` or
-   ``bdist_wininst`` under Python 2.3 and 2.4.
-
- * Add support for "eggsecutable" headers: a ``#!/bin/sh`` script that is
-   prepended to an ``.egg`` file to allow it to be run as a script on Unix-ish
-   platforms.  (This is mainly so that setuptools itself can have a single-file
-   installer on Unix, without doing multiple downloads, dealing with firewalls,
-   etc.)
-
- * Fix problem with empty revision numbers in Subversion 1.4 ``entries`` files
-
- * Use cross-platform relative paths in ``easy-install.pth`` when doing
-   ``develop`` and the source directory is a subdirectory of the installation
-   target directory.
-
- * Fix a problem installing eggs with a system packaging tool if the project
-   contained an implicit namespace package; for example if the ``setup()``
-   listed a namespace package ``foo.bar`` without explicitly listing ``foo``
-   as a namespace package.
-
------
-0.6c3
------
-
- * Fixed breakages caused by Subversion 1.4's new "working copy" format
-
------
-0.6c2
------
-
- * The ``ez_setup`` module displays the conflicting version of setuptools (and
-   its installation location) when a script requests a version that's not
-   available.
-
- * Running ``setup.py develop`` on a setuptools-using project will now install
-   setuptools if needed, instead of only downloading the egg.
-
------
-0.6c1
------
-
- * Fixed ``AttributeError`` when trying to download a ``setup_requires``
-   dependency when a distribution lacks a ``dependency_links`` setting.
-
- * Made ``zip-safe`` and ``not-zip-safe`` flag files contain a single byte, so
-   as to play better with packaging tools that complain about zero-length
-   files.
-
- * Made ``setup.py develop`` respect the ``--no-deps`` option, which it
-   previously was ignoring.
-
- * Support ``extra_path`` option to ``setup()`` when ``install`` is run in
-   backward-compatibility mode.
-
- * Source distributions now always include a ``setup.cfg`` file that explicitly
-   sets ``egg_info`` options such that they produce an identical version number
-   to the source distribution's version number.  (Previously, the default
-   version number could be different due to the use of ``--tag-date``, or if
-   the version was overridden on the command line that built the source
-   distribution.)
-
------
-0.6b4
------
-
- * Fix ``register`` not obeying name/version set by ``egg_info`` command, if
-   ``egg_info`` wasn't explicitly run first on the same command line.
-
- * Added ``--no-date`` and ``--no-svn-revision`` options to ``egg_info``
-   command, to allow suppressing tags configured in ``setup.cfg``.
-
- * Fixed redundant warnings about missing ``README`` file(s); it should now
-   appear only if you are actually a source distribution.
-
------
-0.6b3
------
-
- * Fix ``bdist_egg`` not including files in subdirectories of ``.egg-info``.
-
- * Allow ``.py`` files found by the ``include_package_data`` option to be
-   automatically included.  Remove duplicate data file matches if both
-   ``include_package_data`` and ``package_data`` are used to refer to the same
-   files.
-
------
-0.6b1
------
-
- * Strip ``module`` from the end of compiled extension modules when computing
-   the name of a ``.py`` loader/wrapper.  (Python's import machinery ignores
-   this suffix when searching for an extension module.)
-
-------
-0.6a11
-------
-
- * Added ``test_loader`` keyword to support custom test loaders
-
- * Added ``setuptools.file_finders`` entry point group to allow implementing
-   revision control plugins.
-
- * Added ``--identity`` option to ``upload`` command.
-
- * Added ``dependency_links`` to allow specifying URLs for ``--find-links``.
-
- * Enhanced test loader to scan packages as well as modules, and call
-   ``additional_tests()`` if present to get non-unittest tests.
-
- * Support namespace packages in conjunction with system packagers, by omitting
-   the installation of any ``__init__.py`` files for namespace packages, and
-   adding a special ``.pth`` file to create a working package in
-   ``sys.modules``.
-
- * Made ``--single-version-externally-managed`` automatic when ``--root`` is
-   used, so that most system packagers won't require special support for
-   setuptools.
-
- * Fixed ``setup_requires``, ``tests_require``, etc. not using ``setup.cfg`` or
-   other configuration files for their option defaults when installing, and
-   also made the install use ``--multi-version`` mode so that the project
-   directory doesn't need to support .pth files.
-
- * ``MANIFEST.in`` is now forcibly closed when any errors occur while reading
-   it.  Previously, the file could be left open and the actual error would be
-   masked by problems trying to remove the open file on Windows systems.
-
-------
-0.6a10
-------
-
- * Fixed the ``develop`` command ignoring ``--find-links``.
-
------
-0.6a9
------
-
- * The ``sdist`` command no longer uses the traditional ``MANIFEST`` file to
-   create source distributions.  ``MANIFEST.in`` is still read and processed,
-   as are the standard defaults and pruning.  But the manifest is built inside
-   the project's ``.egg-info`` directory as ``SOURCES.txt``, and it is rebuilt
-   every time the ``egg_info`` command is run.
-
- * Added the ``include_package_data`` keyword to ``setup()``, allowing you to
-   automatically include any package data listed in revision control or
-   ``MANIFEST.in``
-
- * Added the ``exclude_package_data`` keyword to ``setup()``, allowing you to
-   trim back files included via the ``package_data`` and
-   ``include_package_data`` options.
-
- * Fixed ``--tag-svn-revision`` not working when run from a source
-   distribution.
-
- * Added warning for namespace packages with missing ``declare_namespace()``
-
- * Added ``tests_require`` keyword to ``setup()``, so that e.g. packages
-   requiring ``nose`` to run unit tests can make this dependency optional
-   unless the ``test`` command is run.
-
- * Made all commands that use ``easy_install`` respect its configuration
-   options, as this was causing some problems with ``setup.py install``.
-
- * Added an ``unpack_directory()`` driver to ``setuptools.archive_util``, so
-   that you can process a directory tree through a processing filter as if it
-   were a zipfile or tarfile.
-
- * Added an internal ``install_egg_info`` command to use as part of old-style
-   ``install`` operations, that installs an ``.egg-info`` directory with the
-   package.
-
- * Added a ``--single-version-externally-managed`` option to the ``install``
-   command so that you can more easily wrap a "flat" egg in a system package.
-
- * Enhanced ``bdist_rpm`` so that it installs single-version eggs that
-   don't rely on a ``.pth`` file.  The ``--no-egg`` option has been removed,
-   since all RPMs are now built in a more backwards-compatible format.
-
- * Support full roundtrip translation of eggs to and from ``bdist_wininst``
-   format.  Running ``bdist_wininst`` on a setuptools-based package wraps the
-   egg in an .exe that will safely install it as an egg (i.e., with metadata
-   and entry-point wrapper scripts), and ``easy_install`` can turn the .exe
-   back into an ``.egg`` file or directory and install it as such.
-
-
------
-0.6a8
------
-
- * Fixed some problems building extensions when Pyrex was installed, especially
-   with Python 2.4 and/or packages using SWIG.
-
- * Made ``develop`` command accept all the same options as ``easy_install``,
-   and use the ``easy_install`` command's configuration settings as defaults.
-
- * Made ``egg_info --tag-svn-revision`` fall back to extracting the revision
-   number from ``PKG-INFO`` in case it is being run on a source distribution of
-   a snapshot taken from a Subversion-based project.
-
- * Automatically detect ``.dll``, ``.so`` and ``.dylib`` files that are being
-   installed as data, adding them to ``native_libs.txt`` automatically.
-
- * Fixed some problems with fresh checkouts of projects that don't include
-   ``.egg-info/PKG-INFO`` under revision control and put the project's source
-   code directly in the project directory.  If such a package had any
-   requirements that get processed before the ``egg_info`` command can be run,
-   the setup scripts would fail with a "Missing 'Version:' header and/or
-   PKG-INFO file" error, because the egg runtime interpreted the unbuilt
-   metadata in a directory on ``sys.path`` (i.e. the current directory) as
-   being a corrupted egg.  Setuptools now monkeypatches the distribution
-   metadata cache to pretend that the egg has valid version information, until
-   it has a chance to make it actually be so (via the ``egg_info`` command).
-
------
-0.6a5
------
-
- * Fixed missing gui/cli .exe files in distribution.  Fixed bugs in tests.
-
------
-0.6a3
------
-
- * Added ``gui_scripts`` entry point group to allow installing GUI scripts
-   on Windows and other platforms.  (The special handling is only for Windows;
-   other platforms are treated the same as for ``console_scripts``.)
-
------
-0.6a2
------
-
- * Added ``console_scripts`` entry point group to allow installing scripts
-   without the need to create separate script files.  On Windows, console
-   scripts get an ``.exe`` wrapper so you can just type their name.  On other
-   platforms, the scripts are written without a file extension.
-
------
-0.6a1
------
-
- * Added support for building "old-style" RPMs that don't install an egg for
-   the target package, using a ``--no-egg`` option.
-
- * The ``build_ext`` command now works better when using the ``--inplace``
-   option and multiple Python versions.  It now makes sure that all extensions
-   match the current Python version, even if newer copies were built for a
-   different Python version.
-
- * The ``upload`` command no longer attaches an extra ``.zip`` when uploading
-   eggs, as PyPI now supports egg uploads without trickery.
-
- * The ``ez_setup`` script/module now displays a warning before downloading
-   the setuptools egg, and attempts to check the downloaded egg against an
-   internal MD5 checksum table.
-
- * Fixed the ``--tag-svn-revision`` option of ``egg_info`` not finding the
-   latest revision number; it was using the revision number of the directory
-   containing ``setup.py``, not the highest revision number in the project.
-
- * Added ``eager_resources`` setup argument
-
- * The ``sdist`` command now recognizes Subversion "deleted file" entries and
-   does not include them in source distributions.
-
- * ``setuptools`` now embeds itself more thoroughly into the distutils, so that
-   other distutils extensions (e.g. py2exe, py2app) will subclass setuptools'
-   versions of things, rather than the native distutils ones.
-
- * Added ``entry_points`` and ``setup_requires`` arguments to ``setup()``;
-   ``setup_requires`` allows you to automatically find and download packages
-   that are needed in order to *build* your project (as opposed to running it).
-
- * ``setuptools`` now finds its commands, ``setup()`` argument validators, and
-   metadata writers using entry points, so that they can be extended by
-   third-party packages.  See `Creating distutils Extensions
-   <http://pythonhosted.org/setuptools/setuptools.html#creating-distutils-extensions>`_
-   for more details.
-
- * The vestigial ``depends`` command has been removed.  It was never finished
-   or documented, and never would have worked without EasyInstall - which it
-   pre-dated and was never compatible with.
-
-------
-0.5a12
-------
-
- * The zip-safety scanner now checks for modules that might be used with
-   ``python -m``, and marks them as unsafe for zipping, since Python 2.4 can't
-   handle ``-m`` on zipped modules.
-
-------
-0.5a11
-------
-
- * Fix breakage of the "develop" command that was caused by the addition of
-   ``--always-unzip`` to the ``easy_install`` command.
-
------
-0.5a9
------
-
- * Include ``svn:externals`` directories in source distributions as well as
-   normal subversion-controlled files and directories.
-
- * Added ``exclude=patternlist`` option to ``setuptools.find_packages()``
-
- * Changed --tag-svn-revision to include an "r" in front of the revision number
-   for better readability.
-
- * Added ability to build eggs without including source files (except for any
-   scripts, of course), using the ``--exclude-source-files`` option to
-   ``bdist_egg``.
-
- * ``setup.py install`` now automatically detects when an "unmanaged" package
-   or module is going to be on ``sys.path`` ahead of a package being installed,
-   thereby preventing the newer version from being imported.  If this occurs,
-   a warning message is output to ``sys.stderr``, but installation proceeds
-   anyway.  The warning message informs the user what files or directories
-   need deleting, and advises them they can also use EasyInstall (with the
-   ``--delete-conflicting`` option) to do it automatically.
-
- * The ``egg_info`` command now adds a ``top_level.txt`` file to the metadata
-   directory that lists all top-level modules and packages in the distribution.
-   This is used by the ``easy_install`` command to find possibly-conflicting
-   "unmanaged" packages when installing the distribution.
-
- * Added ``zip_safe`` and ``namespace_packages`` arguments to ``setup()``.
-   Added package analysis to determine zip-safety if the ``zip_safe`` flag
-   is not given, and advise the author regarding what code might need changing.
-
- * Fixed the swapped ``-d`` and ``-b`` options of ``bdist_egg``.
-
------
-0.5a8
------
-
- * The "egg_info" command now always sets the distribution metadata to "safe"
-   forms of the distribution name and version, so that distribution files will
-   be generated with parseable names (i.e., ones that don't include '-' in the
-   name or version).  Also, this means that if you use the various ``--tag``
-   options of "egg_info", any distributions generated will use the tags in the
-   version, not just egg distributions.
-
- * Added support for defining command aliases in distutils configuration files,
-   under the "[aliases]" section.  To prevent recursion and to allow aliases to
-   call the command of the same name, a given alias can be expanded only once
-   per command-line invocation.  You can define new aliases with the "alias"
-   command, either for the local, global, or per-user configuration.
-
- * Added "rotate" command to delete old distribution files, given a set of
-   patterns to match and the number of files to keep.  (Keeps the most
-   recently-modified distribution files matching each pattern.)
-
- * Added "saveopts" command that saves all command-line options for the current
-   invocation to the local, global, or per-user configuration file.  Useful for
-   setting defaults without having to hand-edit a configuration file.
-
- * Added a "setopt" command that sets a single option in a specified distutils
-   configuration file.
-
------
-0.5a7
------
-
- * Added "upload" support for egg and source distributions, including a bug
-   fix for "upload" and a temporary workaround for lack of .egg support in
-   PyPI.
-
------
-0.5a6
------
-
- * Beefed up the "sdist" command so that if you don't have a MANIFEST.in, it
-   will include all files under revision control (CVS or Subversion) in the
-   current directory, and it will regenerate the list every time you create a
-   source distribution, not just when you tell it to.  This should make the
-   default "do what you mean" more often than the distutils' default behavior
-   did, while still retaining the old behavior in the presence of MANIFEST.in.
-
- * Fixed the "develop" command always updating .pth files, even if you
-   specified ``-n`` or ``--dry-run``.
-
- * Slightly changed the format of the generated version when you use
-   ``--tag-build`` on the "egg_info" command, so that you can make tagged
-   revisions compare *lower* than the version specified in setup.py (e.g. by
-   using ``--tag-build=dev``).
-
------
-0.5a5
------
-
- * Added ``develop`` command to ``setuptools``-based packages.  This command
-   installs an ``.egg-link`` pointing to the package's source directory, and
-   script wrappers that ``execfile()`` the source versions of the package's
-   scripts.  This lets you put your development checkout(s) on sys.path without
-   having to actually install them.  (To uninstall the link, use
-   use ``setup.py develop --uninstall``.)
-
- * Added ``egg_info`` command to ``setuptools``-based packages.  This command
-   just creates or updates the "projectname.egg-info" directory, without
-   building an egg.  (It's used by the ``bdist_egg``, ``test``, and ``develop``
-   commands.)
-
- * Enhanced the ``test`` command so that it doesn't install the package, but
-   instead builds any C extensions in-place, updates the ``.egg-info``
-   metadata, adds the source directory to ``sys.path``, and runs the tests
-   directly on the source.  This avoids an "unmanaged" installation of the
-   package to ``site-packages`` or elsewhere.
-
- * Made ``easy_install`` a standard ``setuptools`` command, moving it from
-   the ``easy_install`` module to ``setuptools.command.easy_install``.  Note
-   that if you were importing or extending it, you must now change your imports
-   accordingly.  ``easy_install.py`` is still installed as a script, but not as
-   a module.
-
------
-0.5a4
------
-
- * Setup scripts using setuptools can now list their dependencies directly in
-   the setup.py file, without having to manually create a ``depends.txt`` file.
-   The ``install_requires`` and ``extras_require`` arguments to ``setup()``
-   are used to create a dependencies file automatically.  If you are manually
-   creating ``depends.txt`` right now, please switch to using these setup
-   arguments as soon as practical, because ``depends.txt`` support will be
-   removed in the 0.6 release cycle.  For documentation on the new arguments,
-   see the ``setuptools.dist.Distribution`` class.
-
- * Setup scripts using setuptools now always install using ``easy_install``
-   internally, for ease of uninstallation and upgrading.
-
------
-0.5a1
------
-
- * Added support for "self-installation" bootstrapping.  Packages can now
-   include ``ez_setup.py`` in their source distribution, and add the following
-   to their ``setup.py``, in order to automatically bootstrap installation of
-   setuptools as part of their setup process::
-
-    from ez_setup import use_setuptools
-    use_setuptools()
-
-    from setuptools import setup
-    # etc...
-
------
-0.4a2
------
-
- * Added ``ez_setup.py`` installer/bootstrap script to make initial setuptools
-   installation easier, and to allow distributions using setuptools to avoid
-   having to include setuptools in their source distribution.
-
- * All downloads are now managed by the ``PackageIndex`` class (which is now
-   subclassable and replaceable), so that embedders can more easily override
-   download logic, give download progress reports, etc.  The class has also
-   been moved to the new ``setuptools.package_index`` module.
-
- * The ``Installer`` class no longer handles downloading, manages a temporary
-   directory, or tracks the ``zip_ok`` option.  Downloading is now handled
-   by ``PackageIndex``, and ``Installer`` has become an ``easy_install``
-   command class based on ``setuptools.Command``.
-
- * There is a new ``setuptools.sandbox.run_setup()`` API to invoke a setup
-   script in a directory sandbox, and a new ``setuptools.archive_util`` module
-   with an ``unpack_archive()`` API.  These were split out of EasyInstall to
-   allow reuse by other tools and applications.
-
- * ``setuptools.Command`` now supports reinitializing commands using keyword
-   arguments to set/reset options.  Also, ``Command`` subclasses can now set
-   their ``command_consumes_arguments`` attribute to ``True`` in order to
-   receive an ``args`` option containing the rest of the command line.
-
------
-0.3a2
------
-
- * Added new options to ``bdist_egg`` to allow tagging the egg's version number
-   with a subversion revision number, the current date, or an explicit tag
-   value.  Run ``setup.py bdist_egg --help`` to get more information.
-
- * Misc. bug fixes
-
------
-0.3a1
------
-
- * Initial release.

-Installing and Using Setuptools
-===============================
-
-.. contents:: **Table of Contents**
-
-
--------------------------
-Installation Instructions
--------------------------
-
-The recommended way to bootstrap setuptools on any system is to download
-`ez_setup.py`_ and run it using the target Python environment. Different
-operating systems have different recommended techniques to accomplish this
-basic routine, so below are some examples to get you started.
-
-Setuptools requires Python 2.6 or later. To install setuptools
-on Python 2.4 or Python 2.5, use the `bootstrap script for Setuptools 1.x
-<https://bitbucket.org/pypa/setuptools/raw/bootstrap-py24/ez_setup.py>`_.
-
-The link provided to ez_setup.py is a bookmark to bootstrap script for the
-latest known stable release.
-
-.. _ez_setup.py: https://bootstrap.pypa.io/ez_setup.py
-
-Windows 8 (Powershell)
-======================
-
-For best results, uninstall previous versions FIRST (see `Uninstalling`_).
-
-Using Windows 8 or later, it's possible to install with one simple Powershell
-command. Start up Powershell and paste this command::
-
-    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python -
-
-You must start the Powershell with Administrative privileges or you may choose
-to install a user-local installation::
-
-    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python - --user
-
-If you have Python 3.3 or later, you can use the ``py`` command to install to
-different Python versions. For example, to install to Python 3.3 if you have
-Python 2.7 installed::
-
-    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | py -3 -
-
-The recommended way to install setuptools on Windows is to download
-`ez_setup.py`_ and run it. The script will download the appropriate .egg
-file and install it for you.
-
-Once installation is complete, you will find an ``easy_install`` program in
-your Python ``Scripts`` subdirectory.  For simple invocation and best results,
-add this directory to your ``PATH`` environment variable, if it is not already
-present. If you did a user-local install, the ``Scripts`` subdirectory is
-``$env:APPDATA\Python\Scripts``.
-
-
-Windows 7 (or graphical install)
-================================
-
-For Windows 7 and earlier, download `ez_setup.py`_ using your favorite web
-browser or other technique and "run" that file.
-
-
-Unix (wget)
-===========
-
-Most Linux distributions come with wget.
-
-Download `ez_setup.py`_ and run it using the target Python version. The script
-will download the appropriate version and install it for you::
-
-    > wget https://bootstrap.pypa.io/ez_setup.py -O - | python
-
-Note that you will may need to invoke the command with superuser privileges to
-install to the system Python::
-
-    > wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
-
-Alternatively, Setuptools may be installed to a user-local path::
-
-    > wget https://bootstrap.pypa.io/ez_setup.py -O - | python - --user
-
-Unix including Mac OS X (curl)
-==============================
-
-If your system has curl installed, follow the ``wget`` instructions but
-replace ``wget`` with ``curl`` and ``-O`` with ``-o``. For example::
-
-    > curl https://bootstrap.pypa.io/ez_setup.py -o - | python
-
-
-Advanced Installation
-=====================
-
-For more advanced installation options, such as installing to custom
-locations or prefixes, download and extract the source
-tarball from `Setuptools on PyPI <https://pypi.python.org/pypi/setuptools>`_
-and run setup.py with any supported distutils and Setuptools options.
-For example::
-
-    setuptools-x.x$ python setup.py install --prefix=/opt/setuptools
-
-Use ``--help`` to get a full options list, but we recommend consulting
-the `EasyInstall manual`_ for detailed instructions, especially `the section
-on custom installation locations`_.
-
-.. _EasyInstall manual: https://pythonhosted.org/setuptools/EasyInstall
-.. _the section on custom installation locations: https://pythonhosted.org/setuptools/EasyInstall#custom-installation-locations
-
-
-Downloads
-=========
-
-All setuptools downloads can be found at `the project's home page in the Python
-Package Index`_.  Scroll to the very bottom of the page to find the links.
-
-.. _the project's home page in the Python Package Index: https://pypi.python.org/pypi/setuptools
-
-In addition to the PyPI downloads, the development version of ``setuptools``
-is available from the `Bitbucket repo`_, and in-development versions of the
-`0.6 branch`_ are available as well.
-
-.. _Bitbucket repo: https://bitbucket.org/pypa/setuptools/get/default.tar.gz#egg=setuptools-dev
-.. _0.6 branch: http://svn.python.org/projects/sandbox/branches/setuptools-0.6/#egg=setuptools-dev06
-
-Uninstalling
-============
-
-On Windows, if Setuptools was installed using an ``.exe`` or ``.msi``
-installer, simply use the uninstall feature of "Add/Remove Programs" in the
-Control Panel.
-
-Otherwise, to uninstall Setuptools or Distribute, regardless of the Python
-version, delete all ``setuptools*`` and ``distribute*`` files and
-directories from your system's ``site-packages`` directory
-(and any other ``sys.path`` directories) FIRST.
-
-If you are upgrading or otherwise plan to re-install Setuptools or Distribute,
-nothing further needs to be done. If you want to completely remove Setuptools,
-you may also want to remove the 'easy_install' and 'easy_install-x.x' scripts
-and associated executables installed to the Python scripts directory.
-
---------------------------------
-Using Setuptools and EasyInstall
---------------------------------
-
-Here are some of the available manuals, tutorials, and other resources for
-learning about Setuptools, Python Eggs, and EasyInstall:
-
-* `The EasyInstall user's guide and reference manual`_
-* `The setuptools Developer's Guide`_
-* `The pkg_resources API reference`_
-* `Package Compatibility Notes`_ (user-maintained)
-* `The Internal Structure of Python Eggs`_
-
-Questions, comments, and bug reports should be directed to the `distutils-sig
-mailing list`_.  If you have written (or know of) any tutorials, documentation,

-
-* The original design for the ``.egg`` format and the ``pkg_resources`` API was
-  co-created by Phillip Eby and Bob Ippolito.  Bob also implemented the first
-  version of ``pkg_resources``, and supplied the OS X operating system version
-  compatibility algorithm.
-
-* Ian Bicking implemented many early "creature comfort" features of
-  easy_install, including support for downloading via Sourceforge and
-  Subversion repositories.  Ian's comments on the Web-SIG about WSGI
-  application deployment also inspired the concept of "entry points" in eggs,
-  and he has given talks at PyCon and elsewhere to inform and educate the
-  community about eggs and setuptools.
-
-* Jim Fulton contributed time and effort to build automated tests of various
-  aspects of ``easy_install``, and supplied the doctests for the command-line
-  ``.exe`` wrappers on Windows.
-
-* Phillip J. Eby is the seminal author of setuptools, and
-  first proposed the idea of an importable binary distribution format for
-  Python application plug-ins.
-
-* Significant parts of the implementation of setuptools were funded by the Open
-  Source Applications Foundation, to provide a plug-in infrastructure for the
-  Chandler PIM application.  In addition, many OSAF staffers (such as Mike
-  "Code Bear" Taylor) contributed their time and stress as guinea pigs for the
-  use of eggs and setuptools, even before eggs were "cool".  (Thanks, guys!)
-
-* Tarek Ziadé is the principal author of the Distribute fork, which
-  re-invigorated the community on the project, encouraged renewed innovation,
-  and addressed many defects.
-
-* Since the merge with Distribute, Jason R. Coombs is the
-  maintainer of setuptools.  The project is maintained in coordination with
-  the Python Packaging Authority (PyPA) and the larger Python community.

-CHANGES
-=======
-
----
-5.7
----
-
-* `Issue #240 <https://bitbucket.org/pypa/setuptools/issue/240>`_: Based on real-world performance measures against 5.4, zip
-  manifests are now cached in all circumstances. The
-  ``PKG_RESOURCES_CACHE_ZIP_MANIFESTS`` environment variable is no longer
-  relevant. The observed "memory increase" referenced in the 5.4 release
-  notes and detailed in `Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154>`_ was likely not an increase over the status
-  quo, but rather only an increase over not storing the zip info at all.
-
----
-5.6
----
-
-* `Issue #242 <https://bitbucket.org/pypa/setuptools/issue/242>`_: Use absolute imports in svn_utils to avoid issues if the
-  installing package adds an xml module to the path.
-
------
-5.5.1
------
-
-* `Issue #239 <https://bitbucket.org/pypa/setuptools/issue/239>`_: Fix typo in 5.5 such that fix did not take.
-
----
-5.5
----
-
-* `Issue #239 <https://bitbucket.org/pypa/setuptools/issue/239>`_: Setuptools now includes the setup_requires directive on
-  Distribution objects and validates the syntax just like install_requires
-  and tests_require directives.
-
------
-5.4.2
------
-
-* `Issue #236 <https://bitbucket.org/pypa/setuptools/issue/236>`_: Corrected regression in execfile implementation for Python 2.6.

------
-
-* `Python #7776 <http://bugs.python.org/issue7776>`_: (ssl_support) Correct usage of host for validation when
-  tunneling for HTTPS.
-
----
-5.4
----
-
-* `Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154>`_: ``pkg_resources`` will now cache the zip manifests rather than
-  re-processing the same file from disk multiple times, but only if the
-  environment variable ``PKG_RESOURCES_CACHE_ZIP_MANIFESTS`` is set. Clients
-  that package many modules in the same zip file will see some improvement
-  in startup time by enabling this feature. This feature is not enabled by
-  default because it causes a substantial increase in memory usage.
-
----
-5.3
----
-
-* `Issue #185 <https://bitbucket.org/pypa/setuptools/issue/185>`_: Make svn tagging work on the new style SVN metadata.

-5.1
----
-
-* `Issue #202 <https://bitbucket.org/pypa/setuptools/issue/202>`_: Implemented more robust cache invalidation for the ZipImporter,
-  building on the work in `Issue #168 <https://bitbucket.org/pypa/setuptools/issue/168>`_. Special thanks to Jurko Gospodnetic and
-  PJE.
-
------
-5.0.2
------
-
-* `Issue #220 <https://bitbucket.org/pypa/setuptools/issue/220>`_: Restored script templates.
-
------
-5.0.1
------
-
-* Renamed script templates to end with .tmpl now that they no longer need
-  to be processed by 2to3. Fixes spurious syntax errors during build/install.
-
----
-5.0
----
-
-* `Issue #218 <https://bitbucket.org/pypa/setuptools/issue/218>`_: Re-release of 3.8.1 to signal that it supersedes 4.x.

-  broken in 3.4).
-* `Issue #197 <https://bitbucket.org/pypa/setuptools/issue/197>`_: On Python 3.1, PKG-INFO is now saved in a UTF-8 encoding instead
-  of ``sys.getpreferredencoding`` to match the behavior on Python 2.6-3.4.
-* `Issue #192 <https://bitbucket.org/pypa/setuptools/issue/192>`_: Preferred bootstrap location is now
-  https://bootstrap.pypa.io/ez_setup.py (mirrored from former location).
-
------
-3.4.4
------
-
-* `Issue #184 <https://bitbucket.org/pypa/setuptools/issue/184>`_: Correct failure where find_package over-matched packages
-  when directory traversal isn't short-circuited.
-
------
-3.4.3
------
-
-* `Issue #183 <https://bitbucket.org/pypa/setuptools/issue/183>`_: Really fix test command with Python 3.1.

-
-* `Issue #183 <https://bitbucket.org/pypa/setuptools/issue/183>`_: Fix additional regression in test command on Python 3.1.
-
------
-3.4.1

-  runner: --test-runner or -r.
-* `Issue #177 <https://bitbucket.org/pypa/setuptools/issue/177>`_: Now assume most common invocation to install command on
-  platforms/environments without stack support (issuing a warning). Setuptools
-  now installs naturally on IronPython. Behavior on CPython should be
-  unchanged.
-
----
-3.3
----
-
-* Add ``include`` parameter to ``setuptools.find_packages()``.
-
----
-3.2
----
-
-* `Pull Request #39 <https://bitbucket.org/pypa/setuptools/pull-request/39>`_: Add support for C++ targets from Cython ``.pyx`` files.
-* `Issue #162 <https://bitbucket.org/pypa/setuptools/issue/162>`_: Update dependency on certifi to 1.0.1.
-* `Issue #164 <https://bitbucket.org/pypa/setuptools/issue/164>`_: Update dependency on wincertstore to 0.2.
-
----
-3.1
----
-
-* `Issue #161 <https://bitbucket.org/pypa/setuptools/issue/161>`_: Restore Features functionality to allow backward compatibility
-  (for Features) until the uses of that functionality is sufficiently removed.
-
------
-3.0.2
------
-
-* Correct typo in previous bugfix.
-
------
-3.0.1
------
-
-* `Issue #157 <https://bitbucket.org/pypa/setuptools/issue/157>`_: Restore support for Python 2.6 in bootstrap script where
-  ``zipfile.ZipFile`` does not yet have support for context managers.
-
----
-3.0
----
-
-* `Issue #125 <https://bitbucket.org/pypa/setuptools/issue/125>`_: Prevent Subversion support from creating a ~/.subversion
-  directory just for checking the presence of a Subversion repository.
-* `Issue #12 <https://bitbucket.org/pypa/setuptools/issue/12>`_: Namespace packages are now imported lazily.  That is, the mere
-  declaration of a namespace package in an egg on ``sys.path`` no longer
-  causes it to be imported when ``pkg_resources`` is imported.  Note that this
-  change means that all of a namespace package's ``__init__.py`` files must
-  include a ``declare_namespace()`` call in order to ensure that they will be
-  handled properly at runtime.  In 2.x it was possible to get away without
-  including the declaration, but only at the cost of forcing namespace
-  packages to be imported early, which 3.0 no longer does.
-* `Issue #148 <https://bitbucket.org/pypa/setuptools/issue/148>`_: When building (bdist_egg), setuptools no longer adds
-  ``__init__.py`` files to namespace packages. Any packages that rely on this
-  behavior will need to create ``__init__.py`` files and include the
-  ``declare_namespace()``.
-* `Issue #7 <https://bitbucket.org/pypa/setuptools/issue/7>`_: Setuptools itself is now distributed as a zip archive in addition to
-  tar archive. ez_setup.py now uses zip archive. This approach avoids the potential
-  security vulnerabilities presented by use of tar archives in ez_setup.py.
-  It also leverages the security features added to ZipFile.extract in Python 2.7.4.
-* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Removed deprecated Features functionality.
-* `Pull Request #28 <https://bitbucket.org/pypa/setuptools/pull-request/28>`_: Remove backport of ``_bytecode_filenames`` which is
-  available in Python 2.6 and later, but also has better compatibility with
-  Python 3 environments.
-* `Issue #156 <https://bitbucket.org/pypa/setuptools/issue/156>`_: Fix spelling of __PYVENV_LAUNCHER__ variable.
-
----
-2.2
----
-
-* `Issue #141 <https://bitbucket.org/pypa/setuptools/issue/141>`_: Restored fix for allowing setup_requires dependencies to
-  override installed dependencies during setup.
-* `Issue #128 <https://bitbucket.org/pypa/setuptools/issue/128>`_: Fixed issue where only the first dependency link was honored
-  in a distribution where multiple dependency links were supplied.
-
------
-2.1.2

------
-2.1.1
------
-
-* `Issue #139 <https://bitbucket.org/pypa/setuptools/issue/139>`_: Fix regression in re_finder for CVS repos (and maybe Git repos
-  as well).
-
----
-2.1
----
-
-* `Issue #129 <https://bitbucket.org/pypa/setuptools/issue/129>`_: Suppress inspection of ``*.whl`` files when searching for files
-  in a zip-imported file.
-* `Issue #131 <https://bitbucket.org/pypa/setuptools/issue/131>`_: Fix RuntimeError when constructing an egg fetcher.
-
------
-2.0.2
------
-
-* Fix NameError during installation with Python implementations (e.g. Jython)
-  not containing parser module.
-* Fix NameError in ``sdist:re_finder``.
-
------
-2.0.1
------
-
-* `Issue #124 <https://bitbucket.org/pypa/setuptools/issue/124>`_: Fixed error in list detection in upload_docs.
-
----
-2.0
----
-
-* `Issue #121 <https://bitbucket.org/pypa/setuptools/issue/121>`_: Exempt lib2to3 pickled grammars from DirectorySandbox.
-* `Issue #41 <https://bitbucket.org/pypa/setuptools/issue/41>`_: Dropped support for Python 2.4 and Python 2.5. Clients requiring
-  setuptools for those versions of Python should use setuptools 1.x.
-* Removed ``setuptools.command.easy_install.HAS_USER_SITE``. Clients
-  expecting this boolean variable should use ``site.ENABLE_USER_SITE``
-  instead.
-* Removed ``pkg_resources.ImpWrapper``. Clients that expected this class
-  should use ``pkgutil.ImpImporter`` instead.
-
------
-1.4.2
------
-
-* `Issue #116 <https://bitbucket.org/pypa/setuptools/issue/116>`_: Correct TypeError when reading a local package index on Python
-  3.
-
------
-1.4.1
------
-
-* `Issue #114 <https://bitbucket.org/pypa/setuptools/issue/114>`_: Use ``sys.getfilesystemencoding`` for decoding config in
-  ``bdist_wininst`` distributions.
-
-* `Issue #105 <https://bitbucket.org/pypa/setuptools/issue/105>`_ and `Issue #113 <https://bitbucket.org/pypa/setuptools/issue/113>`_: Establish a more robust technique for
-  determining the terminal encoding::
-
-    1. Try ``getpreferredencoding``
-    2. If that returns US_ASCII or None, try the encoding from
-       ``getdefaultlocale``. If that encoding was a "fallback" because Python
-       could not figure it out from the environment or OS, encoding remains
-       unresolved.
-    3. If the encoding is resolved, then make sure Python actually implements
-       the encoding.
-    4. On the event of an error or unknown codec, revert to fallbacks
-       (UTF-8 on Darwin, ASCII on everything else).
-    5. On the encoding is 'mac-roman' on Darwin, use UTF-8 as 'mac-roman' was
-       a bug on older Python releases.
-
-    On a side note, it would seem that the encoding only matters for when SVN
-    does not yet support ``--xml`` and when getting repository and svn version
-    numbers. The ``--xml`` technique should yield UTF-8 according to some
-    messages on the SVN mailing lists. So if the version numbers are always
-    7-bit ASCII clean, it may be best to only support the file parsing methods
-    for legacy SVN releases and support for SVN without the subprocess command
-    would simple go away as support for the older SVNs does.

-
-* `Issue #27 <https://bitbucket.org/pypa/setuptools/issue/27>`_: ``easy_install`` will now use credentials from .pypirc if
-  present for connecting to the package index.
-* `Pull Request #21 <https://bitbucket.org/pypa/setuptools/pull-request/21>`_: Omit unwanted newlines in ``package_index._encode_auth``
-  when the username/password pair length indicates wrapping.
-
------
-1.3.2
------
-
-* `Issue #99 <https://bitbucket.org/pypa/setuptools/issue/99>`_: Fix filename encoding issues in SVN support.
-
------
-1.3.1
------
-
-* Remove exuberant warning in SVN support when SVN is not used.
-
----
-1.3
----
-
-* Address security vulnerability in SSL match_hostname check as reported in
-  `Python #17997 <http://bugs.python.org/issue17997>`_.
-* Prefer `backports.ssl_match_hostname
-  <https://pypi.python.org/pypi/backports.ssl_match_hostname>`_ for backport
-  implementation if present.
-* Correct NameError in ``ssl_support`` module (``socket.error``).
-
----
-1.2
----
-
-* `Issue #26 <https://bitbucket.org/pypa/setuptools/issue/26>`_: Add support for SVN 1.7. Special thanks to Philip Thiem for the
-  contribution.
-* `Issue #93 <https://bitbucket.org/pypa/setuptools/issue/93>`_: Wheels are now distributed with every release. Note that as
-  reported in `Issue #108 <https://bitbucket.org/pypa/setuptools/issue/108>`_, as of Pip 1.4, scripts aren't installed properly
-  from wheels. Therefore, if using Pip to install setuptools from a wheel,
-  the ``easy_install`` command will not be available.
-* Setuptools "natural" launcher support, introduced in 1.0, is now officially
-  supported.
-
------
-1.1.7
------
-
-* Fixed behavior of NameError handling in 'script template (dev).py' (script
-  launcher for 'develop' installs).
-* ``ez_setup.py`` now ensures partial downloads are cleaned up following
-  a failed download.
-* `Distribute #363 <https://bitbucket.org/tarek/distribute/issue/363>`_ and `Issue #55 <https://bitbucket.org/pypa/setuptools/issue/55>`_: Skip an sdist test that fails on locales
-  other than UTF-8.
-
------
-1.1.6
------
-
-* `Distribute #349 <https://bitbucket.org/tarek/distribute/issue/349>`_: ``sandbox.execfile`` now opens the target file in binary
-  mode, thus honoring a BOM in the file when compiled.
-
------
-1.1.5
------
-
-* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Second attempt at fix (logic was reversed).
-
------
-1.1.4
------
-
-* `Issue #77 <https://bitbucket.org/pypa/setuptools/issue/77>`_: Fix error in upload command (Python 2.4).
-
------
-1.1.3
------
-
-* Fix NameError in previous patch.
-
------
-1.1.2
------
-
-* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Correct issue where 404 errors are returned for URLs with
-  fragments in them (such as #egg=).
-
------
-1.1.1
------
-
-* `Issue #75 <https://bitbucket.org/pypa/setuptools/issue/75>`_: Add ``--insecure`` option to ez_setup.py to accommodate
-  environments where a trusted SSL connection cannot be validated.
-* `Issue #76 <https://bitbucket.org/pypa/setuptools/issue/76>`_: Fix AttributeError in upload command with Python 2.4.
-
----
-1.1
----
-
-* `Issue #71 <https://bitbucket.org/pypa/setuptools/issue/71>`_ (`Distribute #333 <https://bitbucket.org/tarek/distribute/issue/333>`_): EasyInstall now puts less emphasis on the
-  condition when a host is blocked via ``--allow-hosts``.
-* `Issue #72 <https://bitbucket.org/pypa/setuptools/issue/72>`_: Restored Python 2.4 compatibility in ``ez_setup.py``.
-
----
-1.0
----
-
-* `Issue #60 <https://bitbucket.org/pypa/setuptools/issue/60>`_: On Windows, Setuptools supports deferring to another launcher,
-  such as Vinay Sajip's `pylauncher <https://bitbucket.org/pypa/pylauncher>`_
-  (included with Python 3.3) to launch console and GUI scripts and not install
-  its own launcher executables. This experimental functionality is currently
-  only enabled if  the ``SETUPTOOLS_LAUNCHER`` environment variable is set to
-  "natural". In the future, this behavior may become default, but only after
-  it has matured and seen substantial adoption. The ``SETUPTOOLS_LAUNCHER``
-  also accepts "executable" to force the default behavior of creating launcher
-  executables.
-* `Issue #63 <https://bitbucket.org/pypa/setuptools/issue/63>`_: Bootstrap script (ez_setup.py) now prefers Powershell, curl, or
-  wget for retrieving the Setuptools tarball for improved security of the
-  install. The script will still fall back to a simple ``urlopen`` on
-  platforms that do not have these tools.
-* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Deprecated the ``Features`` functionality.
-* `Issue #52 <https://bitbucket.org/pypa/setuptools/issue/52>`_: In ``VerifyingHTTPSConn``, handle a tunnelled (proxied)
-  connection.
-
-Backward-Incompatible Changes
-=============================
-
-This release includes a couple of backward-incompatible changes, but most if
-not all users will find 1.0 a drop-in replacement for 0.9.
-
-* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: Normalized API of environment marker support. Specifically,
-  removed line number and filename from SyntaxErrors when returned from
-  `pkg_resources.invalid_marker`. Any clients depending on the specific
-  string representation of exceptions returned by that function may need to
-  be updated to account for this change.
-* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: SyntaxErrors generated by `pkg_resources.invalid_marker` are
-  normalized for cross-implementation consistency.
-* Removed ``--ignore-conflicts-at-my-risk`` and ``--delete-conflicting``
-  options to easy_install. These options have been deprecated since 0.6a11.
-
------
-0.9.8
------
-

-Added several features that were slated for setuptools 0.6c12:
-
-* Index URL now defaults to HTTPS.
-* Added experimental environment marker support. Now clients may designate a
-  PEP-426 environment marker for "extra" dependencies. Setuptools uses this
-  feature in ``setup.py`` for optional SSL and certificate validation support
-  on older platforms. Based on Distutils-SIG discussions, the syntax is
-  somewhat tentative. There should probably be a PEP with a firmer spec before
-  the feature should be considered suitable for use.
-* Added support for SSL certificate validation when installing packages from
-  an HTTPS service.

-* `Distribute #100 <https://bitbucket.org/tarek/distribute/issue/100>`_: making sure there's no SandboxViolation when
-  the setup script patches setuptools.
-
------
-0.6.8
------
-
-* Added "check_packages" in dist. (added in Setuptools 0.6c11)
-* Fixed the DONT_PATCH_SETUPTOOLS state.
-

-0.6.7
------
-
-* `Distribute #58 <https://bitbucket.org/tarek/distribute/issue/58>`_: Added --user support to the develop command
-* `Distribute #11 <https://bitbucket.org/tarek/distribute/issue/11>`_: Generated scripts now wrap their call to the script entry point
-  in the standard "if name == 'main'"
-* Added the 'DONT_PATCH_SETUPTOOLS' environment variable, so virtualenv
-  can drive an installation that doesn't patch a global setuptools.
-* Reviewed unladen-swallow specific change from
-  http://code.google.com/p/unladen-swallow/source/detail?spec=svn875&r=719
-  and determined that it no longer applies. Distribute should work fine with
-  Unladen Swallow 2009Q3.
-* `Distribute #21 <https://bitbucket.org/tarek/distribute/issue/21>`_: Allow PackageIndex.open_url to gracefully handle all cases of a
-  httplib.HTTPException instead of just InvalidURL and BadStatusLine.
-* Removed virtual-python.py from this distribution and updated documentation
-  to point to the actively maintained virtualenv instead.
-* `Distribute #64 <https://bitbucket.org/tarek/distribute/issue/64>`_: use_setuptools no longer rebuilds the distribute egg every
-  time it is run
-* use_setuptools now properly respects the requested version
-* use_setuptools will no longer try to import a distribute egg for the
-  wrong Python version
-* `Distribute #74 <https://bitbucket.org/tarek/distribute/issue/74>`_: no_fake should be True by default.
-* `Distribute #72 <https://bitbucket.org/tarek/distribute/issue/72>`_: avoid a bootstrapping issue with easy_install -U
-
------
-0.6.6
------
-
-* Unified the bootstrap file so it works on both py2.x and py3k without 2to3
-  (patch by Holger Krekel)
-
------
-0.6.5
------
-
-* `Distribute #65 <https://bitbucket.org/tarek/distribute/issue/65>`_: cli.exe and gui.exe are now generated at build time,
-  depending on the platform in use.
-
-* `Distribute #67 <https://bitbucket.org/tarek/distribute/issue/67>`_: Fixed doc typo (PEP 381/382)
-
-* Distribute no longer shadows setuptools if we require a 0.7-series
-  setuptools.  And an error is raised when installing a 0.7 setuptools with
-  distribute.
-
-* When run from within buildout, no attempt is made to modify an existing
-  setuptools egg, whether in a shared egg directory or a system setuptools.
-
-* Fixed a hole in sandboxing allowing builtin file to write outside of
-  the sandbox.
-
------
-0.6.4
------
-
-* Added the generation of `distribute_setup_3k.py` during the release.
-  This closes `Distribute #52 <https://bitbucket.org/tarek/distribute/issue/52>`_.
-
-* Added an upload_docs command to easily upload project documentation to
-  PyPI's https://pythonhosted.org. This close issue `Distribute #56 <https://bitbucket.org/tarek/distribute/issue/56>`_.
-
-* Fixed a bootstrap bug on the use_setuptools() API.

-
------
-0.6c9
------
-
- * Fixed a missing files problem when using Windows source distributions on
-   non-Windows platforms, due to distutils not handling manifest file line
-   endings correctly.
-
- * Updated Pyrex support to work with Pyrex 0.9.6 and higher.
-
- * Minor changes for Jython compatibility, including skipping tests that can't
-   work on Jython.
-
- * Fixed not installing eggs in ``install_requires`` if they were also used for
-   ``setup_requires`` or ``tests_require``.
-
- * Fixed not fetching eggs in ``install_requires`` when running tests.
-
- * Allow ``ez_setup.use_setuptools()`` to upgrade existing setuptools
-   installations when called from a standalone ``setup.py``.
-
- * Added a warning if a namespace package is declared, but its parent package
-   is not also declared as a namespace.
-
- * Support Subversion 1.5
-
- * Removed use of deprecated ``md5`` module if ``hashlib`` is available
-
- * Fixed ``bdist_wininst upload`` trying to upload the ``.exe`` twice
-
- * Fixed ``bdist_egg`` putting a ``native_libs.txt`` in the source package's
-   ``.egg-info``, when it should only be in the built egg's ``EGG-INFO``.
-
- * Ensure that _full_name is set on all shared libs before extensions are
-   checked for shared lib usage.  (Fixes a bug in the experimental shared
-   library build support.)
-
- * Fix to allow unpacked eggs containing native libraries to fail more
-   gracefully under Google App Engine (with an ``ImportError`` loading the
-   C-based module, instead of getting a ``NameError``).
-
------
-0.6c7
------
-
- * Fixed ``distutils.filelist.findall()`` crashing on broken symlinks, and
-   ``egg_info`` command failing on new, uncommitted SVN directories.
-
- * Fix import problems with nested namespace packages installed via
-   ``--root`` or ``--single-version-externally-managed``, due to the
-   parent package not having the child package as an attribute.
-
------
-0.6c6
------
-
- * Added ``--egg-path`` option to ``develop`` command, allowing you to force
-   ``.egg-link`` files to use relative paths (allowing them to be shared across
-   platforms on a networked drive).
-
- * Fix not building binary RPMs correctly.
-
- * Fix "eggsecutables" (such as setuptools' own egg) only being runnable with
-   bash-compatible shells.
-
- * Fix ``#!`` parsing problems in Windows ``.exe`` script wrappers, when there
-   was whitespace inside a quoted argument or at the end of the ``#!`` line
-   (a regression introduced in 0.6c4).
-
- * Fix ``test`` command possibly failing if an older version of the project
-   being tested was installed on ``sys.path`` ahead of the test source
-   directory.
-
- * Fix ``find_packages()`` treating ``ez_setup`` and directories with ``.`` in
-   their names as packages.
-
------
-0.6c5
------
-
- * Fix uploaded ``bdist_rpm`` packages being described as ``bdist_egg``
-   packages under Python versions less than 2.5.
-
- * Fix uploaded ``bdist_wininst`` packages being described as suitable for
-   "any" version by Python 2.5, even if a ``--target-version`` was specified.
-
------
-0.6c4
------
-
- * Overhauled Windows script wrapping to support ``bdist_wininst`` better.
-   Scripts installed with ``bdist_wininst`` will always use ``#!python.exe`` or
-   ``#!pythonw.exe`` as the executable name (even when built on non-Windows
-   platforms!), and the wrappers will look for the executable in the script's
-   parent directory (which should find the right version of Python).
-
- * Fix ``upload`` command not uploading files built by ``bdist_rpm`` or
-   ``bdist_wininst`` under Python 2.3 and 2.4.
-
- * Add support for "eggsecutable" headers: a ``#!/bin/sh`` script that is
-   prepended to an ``.egg`` file to allow it to be run as a script on Unix-ish
-   platforms.  (This is mainly so that setuptools itself can have a single-file
-   installer on Unix, without doing multiple downloads, dealing with firewalls,
-   etc.)
-
- * Fix problem with empty revision numbers in Subversion 1.4 ``entries`` files
-
- * Use cross-platform relative paths in ``easy-install.pth`` when doing
-   ``develop`` and the source directory is a subdirectory of the installation
-   target directory.
-
- * Fix a problem installing eggs with a system packaging tool if the project
-   contained an implicit namespace package; for example if the ``setup()``
-   listed a namespace package ``foo.bar`` without explicitly listing ``foo``
-   as a namespace package.
-
------
-0.6c3
------
-
- * Fixed breakages caused by Subversion 1.4's new "working copy" format
-
------
-0.6c2
------
-
- * The ``ez_setup`` module displays the conflicting version of setuptools (and
-   its installation location) when a script requests a version that's not
-   available.
-
- * Running ``setup.py develop`` on a setuptools-using project will now install
-   setuptools if needed, instead of only downloading the egg.
-
------
-0.6c1
------
-
- * Fixed ``AttributeError`` when trying to download a ``setup_requires``
-   dependency when a distribution lacks a ``dependency_links`` setting.
-
- * Made ``zip-safe`` and ``not-zip-safe`` flag files contain a single byte, so
-   as to play better with packaging tools that complain about zero-length
-   files.
-
- * Made ``setup.py develop`` respect the ``--no-deps`` option, which it
-   previously was ignoring.
-
- * Support ``extra_path`` option to ``setup()`` when ``install`` is run in
-   backward-compatibility mode.
-
- * Source distributions now always include a ``setup.cfg`` file that explicitly
-   sets ``egg_info`` options such that they produce an identical version number
-   to the source distribution's version number.  (Previously, the default
-   version number could be different due to the use of ``--tag-date``, or if
-   the version was overridden on the command line that built the source
-   distribution.)
-
------
-0.6b4
------
-
- * Fix ``register`` not obeying name/version set by ``egg_info`` command, if
-   ``egg_info`` wasn't explicitly run first on the same command line.
-
- * Added ``--no-date`` and ``--no-svn-revision`` options to ``egg_info``
-   command, to allow suppressing tags configured in ``setup.cfg``.
-
- * Fixed redundant warnings about missing ``README`` file(s); it should now
-   appear only if you are actually a source distribution.
-
------
-0.6b3
------
-
- * Fix ``bdist_egg`` not including files in subdirectories of ``.egg-info``.
-
- * Allow ``.py`` files found by the ``include_package_data`` option to be
-   automatically included.  Remove duplicate data file matches if both
-   ``include_package_data`` and ``package_data`` are used to refer to the same
-   files.
-
------
-0.6b1
------
-
- * Strip ``module`` from the end of compiled extension modules when computing
-   the name of a ``.py`` loader/wrapper.  (Python's import machinery ignores
-   this suffix when searching for an extension module.)
-
-------
-0.6a11
-------
-
- * Added ``test_loader`` keyword to support custom test loaders
-
- * Added ``setuptools.file_finders`` entry point group to allow implementing
-   revision control plugins.
-
- * Added ``--identity`` option to ``upload`` command.
-
- * Added ``dependency_links`` to allow specifying URLs for ``--find-links``.
-
- * Enhanced test loader to scan packages as well as modules, and call
-   ``additional_tests()`` if present to get non-unittest tests.
-
- * Support namespace packages in conjunction with system packagers, by omitting
-   the installation of any ``__init__.py`` files for namespace packages, and
-   adding a special ``.pth`` file to create a working package in
-   ``sys.modules``.
-
- * Made ``--single-version-externally-managed`` automatic when ``--root`` is
-   used, so that most system packagers won't require special support for
-   setuptools.
-
- * Fixed ``setup_requires``, ``tests_require``, etc. not using ``setup.cfg`` or
-   other configuration files for their option defaults when installing, and
-   also made the install use ``--multi-version`` mode so that the project
-   directory doesn't need to support .pth files.
-
- * ``MANIFEST.in`` is now forcibly closed when any errors occur while reading
-   it.  Previously, the file could be left open and the actual error would be
-   masked by problems trying to remove the open file on Windows systems.
-
-------
-0.6a10
-------
-
- * Fixed the ``develop`` command ignoring ``--find-links``.
-
------
-0.6a9
------
-
- * The ``sdist`` command no longer uses the traditional ``MANIFEST`` file to
-   create source distributions.  ``MANIFEST.in`` is still read and processed,
-   as are the standard defaults and pruning.  But the manifest is built inside
-   the project's ``.egg-info`` directory as ``SOURCES.txt``, and it is rebuilt
-   every time the ``egg_info`` command is run.
-
- * Added the ``include_package_data`` keyword to ``setup()``, allowing you to
-   automatically include any package data listed in revision control or
-   ``MANIFEST.in``
-
- * Added the ``exclude_package_data`` keyword to ``setup()``, allowing you to
-   trim back files included via the ``package_data`` and
-   ``include_package_data`` options.
-
- * Fixed ``--tag-svn-revision`` not working when run from a source
-   distribution.
-
- * Added warning for namespace packages with missing ``declare_namespace()``
-
- * Added ``tests_require`` keyword to ``setup()``, so that e.g. packages
-   requiring ``nose`` to run unit tests can make this dependency optional
-   unless the ``test`` command is run.
-
- * Made all commands that use ``easy_install`` respect its configuration
-   options, as this was causing some problems with ``setup.py install``.
-
- * Added an ``unpack_directory()`` driver to ``setuptools.archive_util``, so
-   that you can process a directory tree through a processing filter as if it
-   were a zipfile or tarfile.
-
- * Added an internal ``install_egg_info`` command to use as part of old-style
-   ``install`` operations, that installs an ``.egg-info`` directory with the
-   package.
-
- * Added a ``--single-version-externally-managed`` option to the ``install``
-   command so that you can more easily wrap a "flat" egg in a system package.
-
- * Enhanced ``bdist_rpm`` so that it installs single-version eggs that
-   don't rely on a ``.pth`` file.  The ``--no-egg`` option has been removed,
-   since all RPMs are now built in a more backwards-compatible format.
-
- * Support full roundtrip translation of eggs to and from ``bdist_wininst``
-   format.  Running ``bdist_wininst`` on a setuptools-based package wraps the
-   egg in an .exe that will safely install it as an egg (i.e., with metadata
-   and entry-point wrapper scripts), and ``easy_install`` can turn the .exe
-   back into an ``.egg`` file or directory and install it as such.
-
-
------
-0.6a8
------
-
- * Fixed some problems building extensions when Pyrex was installed, especially
-   with Python 2.4 and/or packages using SWIG.
-
- * Made ``develop`` command accept all the same options as ``easy_install``,
-   and use the ``easy_install`` command's configuration settings as defaults.
-
- * Made ``egg_info --tag-svn-revision`` fall back to extracting the revision
-   number from ``PKG-INFO`` in case it is being run on a source distribution of
-   a snapshot taken from a Subversion-based project.
-
- * Automatically detect ``.dll``, ``.so`` and ``.dylib`` files that are being
-   installed as data, adding them to ``native_libs.txt`` automatically.
-
- * Fixed some problems with fresh checkouts of projects that don't include
-   ``.egg-info/PKG-INFO`` under revision control and put the project's source
-   code directly in the project directory.  If such a package had any
-   requirements that get processed before the ``egg_info`` command can be run,
-   the setup scripts would fail with a "Missing 'Version:' header and/or
-   PKG-INFO file" error, because the egg runtime interpreted the unbuilt
-   metadata in a directory on ``sys.path`` (i.e. the current directory) as
-   being a corrupted egg.  Setuptools now monkeypatches the distribution
-   metadata cache to pretend that the egg has valid version information, until
-   it has a chance to make it actually be so (via the ``egg_info`` command).
-
------
-0.6a5
------
-
- * Fixed missing gui/cli .exe files in distribution.  Fixed bugs in tests.
-
------
-0.6a3
------
-
- * Added ``gui_scripts`` entry point group to allow installing GUI scripts
-   on Windows and other platforms.  (The special handling is only for Windows;
-   other platforms are treated the same as for ``console_scripts``.)
-
------
-0.6a2
------
-
- * Added ``console_scripts`` entry point group to allow installing scripts
-   without the need to create separate script files.  On Windows, console
-   scripts get an ``.exe`` wrapper so you can just type their name.  On other
-   platforms, the scripts are written without a file extension.
-
------
-0.6a1
------
-
- * Added support for building "old-style" RPMs that don't install an egg for
-   the target package, using a ``--no-egg`` option.
-
- * The ``build_ext`` command now works better when using the ``--inplace``
-   option and multiple Python versions.  It now makes sure that all extensions
-   match the current Python version, even if newer copies were built for a
-   different Python version.
-
- * The ``upload`` command no longer attaches an extra ``.zip`` when uploading
-   eggs, as PyPI now supports egg uploads without trickery.
-
- * The ``ez_setup`` script/module now displays a warning before downloading
-   the setuptools egg, and attempts to check the downloaded egg against an
-   internal MD5 checksum table.
-
- * Fixed the ``--tag-svn-revision`` option of ``egg_info`` not finding the
-   latest revision number; it was using the revision number of the directory
-   containing ``setup.py``, not the highest revision number in the project.
-
- * Added ``eager_resources`` setup argument
-
- * The ``sdist`` command now recognizes Subversion "deleted file" entries and
-   does not include them in source distributions.
-
- * ``setuptools`` now embeds itself more thoroughly into the distutils, so that
-   other distutils extensions (e.g. py2exe, py2app) will subclass setuptools'
-   versions of things, rather than the native distutils ones.
-
- * Added ``entry_points`` and ``setup_requires`` arguments to ``setup()``;
-   ``setup_requires`` allows you to automatically find and download packages
-   that are needed in order to *build* your project (as opposed to running it).
-
- * ``setuptools`` now finds its commands, ``setup()`` argument validators, and
-   metadata writers using entry points, so that they can be extended by
-   third-party packages.  See `Creating distutils Extensions
-   <http://pythonhosted.org/setuptools/setuptools.html#creating-distutils-extensions>`_
-   for more details.
-
- * The vestigial ``depends`` command has been removed.  It was never finished
-   or documented, and never would have worked without EasyInstall - which it
-   pre-dated and was never compatible with.
-
-------
-0.5a12
-------
-
- * The zip-safety scanner now checks for modules that might be used with
-   ``python -m``, and marks them as unsafe for zipping, since Python 2.4 can't
-   handle ``-m`` on zipped modules.
-
-------
-0.5a11
-------
-
- * Fix breakage of the "develop" command that was caused by the addition of
-   ``--always-unzip`` to the ``easy_install`` command.
-
------
-0.5a9
------
-
- * Include ``svn:externals`` directories in source distributions as well as
-   normal subversion-controlled files and directories.
-
- * Added ``exclude=patternlist`` option to ``setuptools.find_packages()``
-
- * Changed --tag-svn-revision to include an "r" in front of the revision number
-   for better readability.
-
- * Added ability to build eggs without including source files (except for any
-   scripts, of course), using the ``--exclude-source-files`` option to
-   ``bdist_egg``.
-
- * ``setup.py install`` now automatically detects when an "unmanaged" package
-   or module is going to be on ``sys.path`` ahead of a package being installed,
-   thereby preventing the newer version from being imported.  If this occurs,
-   a warning message is output to ``sys.stderr``, but installation proceeds
-   anyway.  The warning message informs the user what files or directories
-   need deleting, and advises them they can also use EasyInstall (with the
-   ``--delete-conflicting`` option) to do it automatically.
-
- * The ``egg_info`` command now adds a ``top_level.txt`` file to the metadata
-   directory that lists all top-level modules and packages in the distribution.
-   This is used by the ``easy_install`` command to find possibly-conflicting
-   "unmanaged" packages when installing the distribution.
-
- * Added ``zip_safe`` and ``namespace_packages`` arguments to ``setup()``.
-   Added package analysis to determine zip-safety if the ``zip_safe`` flag
-   is not given, and advise the author regarding what code might need changing.
-
- * Fixed the swapped ``-d`` and ``-b`` options of ``bdist_egg``.
-
------
-0.5a8
------
-
- * The "egg_info" command now always sets the distribution metadata to "safe"
-   forms of the distribution name and version, so that distribution files will
-   be generated with parseable names (i.e., ones that don't include '-' in the
-   name or version).  Also, this means that if you use the various ``--tag``
-   options of "egg_info", any distributions generated will use the tags in the
-   version, not just egg distributions.
-
- * Added support for defining command aliases in distutils configuration files,
-   under the "[aliases]" section.  To prevent recursion and to allow aliases to
-   call the command of the same name, a given alias can be expanded only once
-   per command-line invocation.  You can define new aliases with the "alias"
-   command, either for the local, global, or per-user configuration.
-
- * Added "rotate" command to delete old distribution files, given a set of
-   patterns to match and the number of files to keep.  (Keeps the most
-   recently-modified distribution files matching each pattern.)
-
- * Added "saveopts" command that saves all command-line options for the current
-   invocation to the local, global, or per-user configuration file.  Useful for
-   setting defaults without having to hand-edit a configuration file.
-
- * Added a "setopt" command that sets a single option in a specified distutils
-   configuration file.
-
------
-0.5a7
------
-
- * Added "upload" support for egg and source distributions, including a bug
-   fix for "upload" and a temporary workaround for lack of .egg support in
-   PyPI.
-
------
-0.5a6
------
-
- * Beefed up the "sdist" command so that if you don't have a MANIFEST.in, it
-   will include all files under revision control (CVS or Subversion) in the
-   current directory, and it will regenerate the list every time you create a
-   source distribution, not just when you tell it to.  This should make the
-   default "do what you mean" more often than the distutils' default behavior
-   did, while still retaining the old behavior in the presence of MANIFEST.in.
-
- * Fixed the "develop" command always updating .pth files, even if you
-   specified ``-n`` or ``--dry-run``.
-
- * Slightly changed the format of the generated version when you use
-   ``--tag-build`` on the "egg_info" command, so that you can make tagged
-   revisions compare *lower* than the version specified in setup.py (e.g. by
-   using ``--tag-build=dev``).
-
------
-0.5a5
------
-
- * Added ``develop`` command to ``setuptools``-based packages.  This command
-   installs an ``.egg-link`` pointing to the package's source directory, and
-   script wrappers that ``execfile()`` the source versions of the package's
-   scripts.  This lets you put your development checkout(s) on sys.path without
-   having to actually install them.  (To uninstall the link, use
-   use ``setup.py develop --uninstall``.)
-
- * Added ``egg_info`` command to ``setuptools``-based packages.  This command
-   just creates or updates the "projectname.egg-info" directory, without
-   building an egg.  (It's used by the ``bdist_egg``, ``test``, and ``develop``
-   commands.)
-
- * Enhanced the ``test`` command so that it doesn't install the package, but
-   instead builds any C extensions in-place, updates the ``.egg-info``
-   metadata, adds the source directory to ``sys.path``, and runs the tests
-   directly on the source.  This avoids an "unmanaged" installation of the
-   package to ``site-packages`` or elsewhere.
-
- * Made ``easy_install`` a standard ``setuptools`` command, moving it from
-   the ``easy_install`` module to ``setuptools.command.easy_install``.  Note
-   that if you were importing or extending it, you must now change your imports
-   accordingly.  ``easy_install.py`` is still installed as a script, but not as
-   a module.
-
------
-0.5a4
------
-
- * Setup scripts using setuptools can now list their dependencies directly in
-   the setup.py file, without having to manually create a ``depends.txt`` file.
-   The ``install_requires`` and ``extras_require`` arguments to ``setup()``
-   are used to create a dependencies file automatically.  If you are manually
-   creating ``depends.txt`` right now, please switch to using these setup
-   arguments as soon as practical, because ``depends.txt`` support will be
-   removed in the 0.6 release cycle.  For documentation on the new arguments,
-   see the ``setuptools.dist.Distribution`` class.
-
- * Setup scripts using setuptools now always install using ``easy_install``
-   internally, for ease of uninstallation and upgrading.
-
------
-0.5a1
------
-
- * Added support for "self-installation" bootstrapping.  Packages can now
-   include ``ez_setup.py`` in their source distribution, and add the following
-   to their ``setup.py``, in order to automatically bootstrap installation of
-   setuptools as part of their setup process::
-
-    from ez_setup import use_setuptools
-    use_setuptools()
-
-    from setuptools import setup
-    # etc...
-
------
-0.4a2
------
-
- * Added ``ez_setup.py`` installer/bootstrap script to make initial setuptools
-   installation easier, and to allow distributions using setuptools to avoid
-   having to include setuptools in their source distribution.
-
- * All downloads are now managed by the ``PackageIndex`` class (which is now
-   subclassable and replaceable), so that embedders can more easily override
-   download logic, give download progress reports, etc.  The class has also
-   been moved to the new ``setuptools.package_index`` module.
-
- * The ``Installer`` class no longer handles downloading, manages a temporary
-   directory, or tracks the ``zip_ok`` option.  Downloading is now handled
-   by ``PackageIndex``, and ``Installer`` has become an ``easy_install``
-   command class based on ``setuptools.Command``.
-
- * There is a new ``setuptools.sandbox.run_setup()`` API to invoke a setup
-   script in a directory sandbox, and a new ``setuptools.archive_util`` module
-   with an ``unpack_archive()`` API.  These were split out of EasyInstall to
-   allow reuse by other tools and applications.
-
- * ``setuptools.Command`` now supports reinitializing commands using keyword
-   arguments to set/reset options.  Also, ``Command`` subclasses can now set
-   their ``command_consumes_arguments`` attribute to ``True`` in order to
-   receive an ``args`` option containing the rest of the command line.
-
------
-0.3a2
------
-
- * Added new options to ``bdist_egg`` to allow tagging the egg's version number
-   with a subversion revision number, the current date, or an explicit tag
-   value.  Run ``setup.py bdist_egg --help`` to get more information.
-
- * Misc. bug fixes
-
------
-0.3a1
------
-
- * Initial release.

-Six is a Python 2 and 3 compatibility library.  It provides utility functions
-for smoothing over the differences between the Python versions with the goal of
-writing Python code that is compatible on both Python versions.  See the
-documentation for more information on what is provided.
-
-Six supports every Python version since 2.5.  It is contained in only one Python
-file, so it can be easily copied into your project. (The copyright and license
-notice must be retained.)
-
-Online documentation is at http://pythonhosted.org/six/.
-
-Bugs can be reported to http://bitbucket.org/gutworth/six.  The code can also be
-found there.
-
-For questions about six or porting in general, email the python-porting mailing
-list: http://mail.python.org/mailman/listinfo/python-porting

+Metadata-Version: 1.1
+Name: PyPDF2
+Version: 1.23
+Summary: PDF toolkit
+Home-page: http://mstamy2.github.com/PyPDF2
+Author: Phaseit, Inc.
+Author-email: PyPDF2@phaseit.net
+License: UNKNOWN
+Description: 
+        A Pure-Python library built as a PDF toolkit.  It is capable of:
+            
+        - extracting document information (title, author, ...)
+        - splitting documents page by page
+        - merging documents page by page
+        - cropping pages
+        - merging multiple pages into a single page
+        - encrypting and decrypting PDF files
+        - and more!
+        
+        By being Pure-Python, it should run on any Python platform without any
+        dependencies on external libraries.  It can also work entirely on StringIO
+        objects rather than file streams, allowing for PDF manipulation in memory.
+        It is therefore a useful tool for websites that manage or manipulate PDFs.
+

+# What is the PDFX namespace, you might ask?  I might ask that too.  It's
+# a completely undocumented namespace used to place "custom metadata"
+# properties, which are arbitrary metadata properties with no semantic or
+# documented meaning.  Elements in the namespace are key/value-style storage,
+# where the element name is the key and the content is the value.  The keys
+# are transformed into valid XML identifiers by substituting an invalid
+# identifier character with \u2182 followed by the unicode hex ID of the
+# original character.  A key like "my car" is therefore "my\u21820020car".
+#
+# \u2182, in case you're wondering, is the unicode character
+# \u{ROMAN NUMERAL TEN THOUSAND}, a straightforward and obvious choice for
+# escaping characters.
+#
+# Intentional users of the pdfx namespace should be shot on sight.  A
+# custom data schema and sensical XML elements could be used instead, as is
+# suggested by Adobe's own documentation on XMP (under "Extensibility of
+# Schemas").
+#
+# Information presented here on the /pdfx/ schema is a result of limited
+# reverse engineering, and does not constitute a full specification.

+    # application/xml-external-parsed-entity, or application/xml-dtd,
+    # the encoding given in the charset parameter of the HTTP Content-Type
+    # takes precedence over the encoding given in the XML prefix within the
+    # document, and defaults to 'utf-8' if neither are specified.  But, if
+    # the HTTP Content-Type is text/xml, text/*+xml, or
+    # text/xml-external-parsed-entity, the encoding given in the XML prefix
+    # within the document is ALWAYS IGNORED and only the encoding given in
+    # the charset parameter of the HTTP Content-Type header should be
+    # respected, and it defaults to 'us-ascii' if not specified.
+
+    # Furthermore, discussion on the atom-syntax mailing list with the
+    # author of RFC 3023 leads me to the conclusion that any document
+    # served with a Content-Type of text/* and no charset parameter
+    # must be treated as us-ascii.  (We now do this.)  And also that it
+    # must always be flagged as non-well-formed.  (We now do this too.)
+

+    # or unrecognized (server just got it totally wrong), then go by the
+    # encoding given in the XML prefix of the document and default to
+    # 'iso-8859-1' as per the HTTP specification (RFC 2616).
+
+    # Then, assuming we didn't find a character encoding in the HTTP headers
+    # (and the HTTP Content-type allowed us to look in the body), we need
+    # to sniff the first few bytes of the XML data and try to determine

+
+    # If the sniffed encoding is not ASCII-compatible, we need to make it
+    # ASCII compatible so that we can sniff further into the XML declaration
+    # to find the encoding attribute, which will tell us the true encoding.
+
+    # Of course, none of this guarantees that we will be able to parse the

     Something you will find all over the place, in real-world text, is text

     auto-decode bytes for you -- then it would just create the problems it's

     Because these characters often come from Microsoft products, we allow
     for the possibility that we get not just Unicode characters 128-255, but
     also Windows's conflicting idea of what characters 128-160 are.
 
-        >>> print fix_bad_unicode(u'This � should be an em dash')
-        This — should be an em dash
+        >>> fix_bad_unicode('This � should be an em dash')
+        'This — should be an em dash'
 
     We might have to deal with both Windows characters and raw control
     characters at the same time, especially when dealing with characters like
     \x81 that have no mapping in Windows.
 
-        >>> print fix_bad_unicode(u'This text is sad .â\x81�.')
-        This text is sad .�.
+        >>> fix_bad_unicode('This text is sad .â\x81�.')
+        'This text is sad .�.'
 
     This function even fixes multiple levels of badness:
 
-        >>> wtf = u'\xc3\xa0\xc2\xb2\xc2\xa0_\xc3\xa0\xc2\xb2\xc2\xa0'
-        >>> print fix_bad_unicode(wtf)
-        ಠ_ಠ
+        >>> wtf = '\xc3\xa0\xc2\xb2\xc2\xa0_\xc3\xa0\xc2\xb2\xc2\xa0'
+        >>> fix_bad_unicode(wtf)
+        'ಠ_ಠ'
 
     However, it has safeguards against fixing sequences of letters and
     punctuation that can occur in valid text:
 
-        >>> print fix_bad_unicode(u'not such a fan of Charlotte Brontë…�')
-        not such a fan of Charlotte Brontë…�
+        >>> fix_bad_unicode('not such a fan of Charlotte Brontë…�')
+        'not such a fan of Charlotte Brontë…�'
 
     Cases of genuine ambiguity can sometimes be addressed by finding other
     characters that are not double-encoding, and expecting the encoding to
     be consistent:
 
-        >>> print fix_bad_unicode(u'AHÅ™, the new sofa from IKEA®')
-        AHÅ™, the new sofa from IKEA®

+Package resource API
+--------------------
+
+A resource is a logical file contained within a package, or a logical
+subdirectory thereof.  The package resource API expects resource names
+to have their path parts separated with ``/``, *not* whatever the local
+path separator is.  Do not use os.path operations to manipulate resource
+names being passed into the API.
+
+The package resource API is designed to work with normal filesystem packages,
+.egg files, and unpacked .egg files.  It can also work in a limited way with
+.zip files and with custom PEP 302 loaders that support the ``get_data()``
+method.

+
+    Finally, to handle miscellaneous cases, the strings "pre", "preview", and
+    "rc" are treated as if they were "c", i.e. as though they were release
+    candidates, and therefore are not as new as a version string that does not

+===============================
+Installing and Using Setuptools
+===============================
+
+.. contents:: **Table of Contents**
+
+
+-------------------------
+Installation Instructions
+-------------------------
+
+The recommended way to bootstrap setuptools on any system is to download
+`ez_setup.py`_ and run it using the target Python environment. Different
+operating systems have different recommended techniques to accomplish this
+basic routine, so below are some examples to get you started.
+
+Setuptools requires Python 2.6 or later. To install setuptools
+on Python 2.4 or Python 2.5, use the `bootstrap script for Setuptools 1.x
+<https://bitbucket.org/pypa/setuptools/raw/bootstrap-py24/ez_setup.py>`_.
+
+The link provided to ez_setup.py is a bookmark to bootstrap script for the
+latest known stable release.
+
+.. _ez_setup.py: https://bootstrap.pypa.io/ez_setup.py
+
+Windows (Powershell 3 or later)
+===============================
+
+For best results, uninstall previous versions FIRST (see `Uninstalling`_).
+
+Using Windows 8 (which includes PowerShell 3) or earlier versions of Windows
+with PowerShell 3 installed, it's possible to install with one simple
+Powershell command. Start up Powershell and paste this command::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python -
+
+You must start the Powershell with Administrative privileges or you may choose
+to install a user-local installation::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python - --user
+
+If you have Python 3.3 or later, you can use the ``py`` command to install to
+different Python versions. For example, to install to Python 3.3 if you have
+Python 2.7 installed::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | py -3 -
+
+The recommended way to install setuptools on Windows is to download
+`ez_setup.py`_ and run it. The script will download the appropriate
+distribution file and install it for you.
+
+Once installation is complete, you will find an ``easy_install`` program in
+your Python ``Scripts`` subdirectory.  For simple invocation and best results,
+add this directory to your ``PATH`` environment variable, if it is not already
+present. If you did a user-local install, the ``Scripts`` subdirectory is
+``$env:APPDATA\Python\Scripts``.
+
+
+Windows (simplified)
+====================
+
+For Windows without PowerShell 3 or for installation without a command-line,
+download `ez_setup.py`_ using your preferred web browser or other technique
+and "run" that file.
+
+
+Unix (wget)
+===========
+
+Most Linux distributions come with wget.
+
+Download `ez_setup.py`_ and run it using the target Python version. The script
+will download the appropriate version and install it for you::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | python
+
+Note that you will may need to invoke the command with superuser privileges to
+install to the system Python::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
+
+Alternatively, Setuptools may be installed to a user-local path::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | python - --user
+
+Unix including Mac OS X (curl)
+==============================
+
+If your system has curl installed, follow the ``wget`` instructions but
+replace ``wget`` with ``curl`` and ``-O`` with ``-o``. For example::
+
+    > curl https://bootstrap.pypa.io/ez_setup.py -o - | python
+
+
+Advanced Installation
+=====================
+
+For more advanced installation options, such as installing to custom
+locations or prefixes, download and extract the source
+tarball from `Setuptools on PyPI <https://pypi.python.org/pypi/setuptools>`_
+and run setup.py with any supported distutils and Setuptools options.
+For example::
+
+    setuptools-x.x$ python setup.py install --prefix=/opt/setuptools
+

+
+In addition to the PyPI downloads, the development version of ``setuptools``
+is available from the `Bitbucket repo`_, and in-development versions of the
+`0.6 branch`_ are available as well.
+
+.. _Bitbucket repo: https://bitbucket.org/pypa/setuptools/get/default.tar.gz#egg=setuptools-dev
+.. _0.6 branch: http://svn.python.org/projects/sandbox/branches/setuptools-0.6/#egg=setuptools-dev06
+
+Uninstalling
+============
+
+On Windows, if Setuptools was installed using an ``.exe`` or ``.msi``
+installer, simply use the uninstall feature of "Add/Remove Programs" in the
+Control Panel.
+
+Otherwise, to uninstall Setuptools or Distribute, regardless of the Python
+version, delete all ``setuptools*`` and ``distribute*`` files and
+directories from your system's ``site-packages`` directory
+(and any other ``sys.path`` directories) FIRST.
+
+If you are upgrading or otherwise plan to re-install Setuptools or Distribute,
+nothing further needs to be done. If you want to completely remove Setuptools,
+you may also want to remove the 'easy_install' and 'easy_install-x.x' scripts
+and associated executables installed to the Python scripts directory.
+
+--------------------------------
+Using Setuptools and EasyInstall

+* `The pkg_resources API reference`_
+* `Package Compatibility Notes`_ (user-maintained)
+* `The Internal Structure of Python Eggs`_
+
+Questions, comments, and bug reports should be directed to the `distutils-sig
+mailing list`_.  If you have written (or know of) any tutorials, documentation,
+plug-ins, or other resources for setuptools users, please let us know about
+them there, so this reference list can be updated.  If you have working,
+*tested* patches to correct problems or add features, you may submit them to

+
+* The original design for the ``.egg`` format and the ``pkg_resources`` API was
+  co-created by Phillip Eby and Bob Ippolito.  Bob also implemented the first
+  version of ``pkg_resources``, and supplied the OS X operating system version
+  compatibility algorithm.
+
+* Ian Bicking implemented many early "creature comfort" features of
+  easy_install, including support for downloading via Sourceforge and
+  Subversion repositories.  Ian's comments on the Web-SIG about WSGI
+  application deployment also inspired the concept of "entry points" in eggs,
+  and he has given talks at PyCon and elsewhere to inform and educate the
+  community about eggs and setuptools.
+
+* Jim Fulton contributed time and effort to build automated tests of various
+  aspects of ``easy_install``, and supplied the doctests for the command-line
+  ``.exe`` wrappers on Windows.
+
+* Phillip J. Eby is the seminal author of setuptools, and
+  first proposed the idea of an importable binary distribution format for
+  Python application plug-ins.
+
+* Significant parts of the implementation of setuptools were funded by the Open
+  Source Applications Foundation, to provide a plug-in infrastructure for the
+  Chandler PIM application.  In addition, many OSAF staffers (such as Mike
+  "Code Bear" Taylor) contributed their time and stress as guinea pigs for the
+  use of eggs and setuptools, even before eggs were "cool".  (Thanks, guys!)
+
+* Tarek Ziadé is the principal author of the Distribute fork, which
+  re-invigorated the community on the project, encouraged renewed innovation,
+  and addressed many defects.
+
+* Since the merge with Distribute, Jason R. Coombs is the
+  maintainer of setuptools.  The project is maintained in coordination with
+  the Python Packaging Authority (PyPA) and the larger Python community.

+CHANGES
+=======
+
+-----
+6.0.2
+-----
+
+* `Issue #262 <https://bitbucket.org/pypa/setuptools/issue/262>`_: Fixed regression in pip install due to egg-info directories
+  being omitted. Re-opens `Issue #118 <https://bitbucket.org/pypa/setuptools/issue/118>`_.
+
+-----
+6.0.1
+-----
+
+* `Issue #259 <https://bitbucket.org/pypa/setuptools/issue/259>`_: Fixed regression with namespace package handling on ``single
+  version, externally managed`` installs.
+
+---
+6.0
+---
+
+* `Issue #100 <https://bitbucket.org/pypa/setuptools/issue/100>`_: When building a distribution, Setuptools will no longer match
+  default files using platform-dependent case sensitivity, but rather will
+  only match the files if their case matches exactly. As a result, on Windows
+  and other case-insensitive file systems, files with names such as
+  'readme.txt' or 'README.TXT' will be omitted from the distribution and a
+  warning will be issued indicating that 'README.txt' was not found. Other
+  filenames affected are:
+
+    - README.rst
+    - README
+    - setup.cfg
+    - setup.py (or the script name)
+    - test/test*.py
+
+  Any users producing distributions with filenames that match those above
+  case-insensitively, but not case-sensitively, should rename those files in
+  their repository for better portability.
+* `Pull Request #72 <https://bitbucket.org/pypa/setuptools/pull-request/72>`_: When using ``single_version_externally_managed``, the
+  exclusion list now includes Python 3.2 ``__pycache__`` entries.
+* `Pull Request #76 <https://bitbucket.org/pypa/setuptools/pull-request/76>`_ and `Pull Request #78 <https://bitbucket.org/pypa/setuptools/pull-request/78>`_: lines in top_level.txt are now
+  ordered deterministically.
+* `Issue #118 <https://bitbucket.org/pypa/setuptools/issue/118>`_: The egg-info directory is now no longer included in the list
+  of outputs.
+* `Issue #258 <https://bitbucket.org/pypa/setuptools/issue/258>`_: Setuptools now patches distutils msvc9compiler to
+  recognize the specially-packaged compiler package for easy extension module
+  support on Python 2.6, 2.7, and 3.2.
+
+---
+5.8
+---
+
+* `Issue #237 <https://bitbucket.org/pypa/setuptools/issue/237>`_: ``pkg_resources`` now uses explicit detection of Python 2 vs.
+  Python 3, supporting environments where builtins have been patched to make
+  Python 3 look more like Python 2.
+
+---
+5.7
+---
+
+* `Issue #240 <https://bitbucket.org/pypa/setuptools/issue/240>`_: Based on real-world performance measures against 5.4, zip
+  manifests are now cached in all circumstances. The
+  ``PKG_RESOURCES_CACHE_ZIP_MANIFESTS`` environment variable is no longer
+  relevant. The observed "memory increase" referenced in the 5.4 release
+  notes and detailed in `Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154>`_ was likely not an increase over the status
+  quo, but rather only an increase over not storing the zip info at all.
+
+---
+5.6
+---
+
+* `Issue #242 <https://bitbucket.org/pypa/setuptools/issue/242>`_: Use absolute imports in svn_utils to avoid issues if the
+  installing package adds an xml module to the path.
+
+-----
+5.5.1
+-----
+
+* `Issue #239 <https://bitbucket.org/pypa/setuptools/issue/239>`_: Fix typo in 5.5 such that fix did not take.
+
+---
+5.5
+---
+
+* `Issue #239 <https://bitbucket.org/pypa/setuptools/issue/239>`_: Setuptools now includes the setup_requires directive on
+  Distribution objects and validates the syntax just like install_requires
+  and tests_require directives.
+
+-----
+5.4.2
+-----
+
+* `Issue #236 <https://bitbucket.org/pypa/setuptools/issue/236>`_: Corrected regression in execfile implementation for Python 2.6.
+
+-----
+5.4.1
+-----
+
+* `Python #7776 <http://bugs.python.org/issue7776>`_: (ssl_support) Correct usage of host for validation when
+  tunneling for HTTPS.
+
+---
+5.4
+---
+
+* `Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154>`_: ``pkg_resources`` will now cache the zip manifests rather than
+  re-processing the same file from disk multiple times, but only if the
+  environment variable ``PKG_RESOURCES_CACHE_ZIP_MANIFESTS`` is set. Clients
+  that package many modules in the same zip file will see some improvement
+  in startup time by enabling this feature. This feature is not enabled by
+  default because it causes a substantial increase in memory usage.
+
+---
+5.3
+---
+
+* `Issue #185 <https://bitbucket.org/pypa/setuptools/issue/185>`_: Make svn tagging work on the new style SVN metadata.
+  Thanks cazabon!
+* Prune revision control directories (e.g .svn) from base path
+  as well as sub-directories.
+
+---
+5.2
+---
+
+* Added a `Developer Guide
+  <https://pythonhosted.org/setuptools/developer-guide.html>`_ to the official
+  documentation.
+* Some code refactoring and cleanup was done with no intended behavioral
+  changes.
+* During install_egg_info, the generated lines for namespace package .pth
+  files are now processed even during a dry run.
+
+---
+5.1
+---
+
+* `Issue #202 <https://bitbucket.org/pypa/setuptools/issue/202>`_: Implemented more robust cache invalidation for the ZipImporter,
+  building on the work in `Issue #168 <https://bitbucket.org/pypa/setuptools/issue/168>`_. Special thanks to Jurko Gospodnetic and
+  PJE.
+
+-----
+5.0.2
+-----
+
+* `Issue #220 <https://bitbucket.org/pypa/setuptools/issue/220>`_: Restored script templates.
+
+-----
+5.0.1
+-----
+
+* Renamed script templates to end with .tmpl now that they no longer need
+  to be processed by 2to3. Fixes spurious syntax errors during build/install.
+
+---
+5.0
+---
+
+* `Issue #218 <https://bitbucket.org/pypa/setuptools/issue/218>`_: Re-release of 3.8.1 to signal that it supersedes 4.x.
+* Incidentally, script templates were updated not to include the triple-quote
+  escaping.
+
+-------------------------
+3.7.1 and 3.8.1 and 4.0.1
+-------------------------
+
+* `Issue #213 <https://bitbucket.org/pypa/setuptools/issue/213>`_: Use legacy StringIO behavior for compatibility under pbr.
+* `Issue #218 <https://bitbucket.org/pypa/setuptools/issue/218>`_: Setuptools 3.8.1 superseded 4.0.1, and 4.x was removed
+  from the available versions to install.
+
+---
+4.0
+---
+
+* `Issue #210 <https://bitbucket.org/pypa/setuptools/issue/210>`_: ``setup.py develop`` now copies scripts in binary mode rather
+  than text mode, matching the behavior of the ``install`` command.
+
+---
+3.8
+---
+
+* Extend `Issue #197 <https://bitbucket.org/pypa/setuptools/issue/197>`_ workaround to include all Python 3 versions prior to
+  3.2.2.
+
+---
+3.7
+---
+
+* `Issue #193 <https://bitbucket.org/pypa/setuptools/issue/193>`_: Improved handling of Unicode filenames when building manifests.
+
+---
+3.6
+---

+  routine.
+
+-----
+3.5.2
+-----
+
+* `Issue #168 <https://bitbucket.org/pypa/setuptools/issue/168>`_: More robust handling of replaced zip files and stale caches.
+  Fixes ZipImportError complaining about a 'bad local header'.
+
+-----
+3.5.1
+-----
+
+* `Issue #199 <https://bitbucket.org/pypa/setuptools/issue/199>`_: Restored ``install._install`` for compatibility with earlier
+  NumPy versions.
+
+---
+3.5
+---
+
+* `Issue #195 <https://bitbucket.org/pypa/setuptools/issue/195>`_: Follow symbolic links in find_packages (restoring behavior
+  broken in 3.4).
+* `Issue #197 <https://bitbucket.org/pypa/setuptools/issue/197>`_: On Python 3.1, PKG-INFO is now saved in a UTF-8 encoding instead
+  of ``sys.getpreferredencoding`` to match the behavior on Python 2.6-3.4.
+* `Issue #192 <https://bitbucket.org/pypa/setuptools/issue/192>`_: Preferred bootstrap location is now
+  https://bootstrap.pypa.io/ez_setup.py (mirrored from former location).
+
+-----
+3.4.4
+-----
+
+* `Issue #184 <https://bitbucket.org/pypa/setuptools/issue/184>`_: Correct failure where find_package over-matched packages
+  when directory traversal isn't short-circuited.
+
+-----
+3.4.3
+-----
+
+* `Issue #183 <https://bitbucket.org/pypa/setuptools/issue/183>`_: Really fix test command with Python 3.1.
+
+-----
+3.4.2
+-----
+

+
+-----
+3.4.1
+-----
+
+* `Issue #180 <https://bitbucket.org/pypa/setuptools/issue/180>`_: Fix regression in test command not caught by py.test-run tests.
+
+---
+3.4
+---
+
+* `Issue #176 <https://bitbucket.org/pypa/setuptools/issue/176>`_: Add parameter to the test command to support a custom test
+  runner: --test-runner or -r.
+* `Issue #177 <https://bitbucket.org/pypa/setuptools/issue/177>`_: Now assume most common invocation to install command on
+  platforms/environments without stack support (issuing a warning). Setuptools
+  now installs naturally on IronPython. Behavior on CPython should be
+  unchanged.
+
+---
+3.3
+---
+
+* Add ``include`` parameter to ``setuptools.find_packages()``.
+
+---
+3.2
+---
+
+* `Pull Request #39 <https://bitbucket.org/pypa/setuptools/pull-request/39>`_: Add support for C++ targets from Cython ``.pyx`` files.
+* `Issue #162 <https://bitbucket.org/pypa/setuptools/issue/162>`_: Update dependency on certifi to 1.0.1.
+* `Issue #164 <https://bitbucket.org/pypa/setuptools/issue/164>`_: Update dependency on wincertstore to 0.2.
+
+---
+3.1
+---
+
+* `Issue #161 <https://bitbucket.org/pypa/setuptools/issue/161>`_: Restore Features functionality to allow backward compatibility
+  (for Features) until the uses of that functionality is sufficiently removed.
+
+-----
+3.0.2
+-----
+
+* Correct typo in previous bugfix.
+
+-----
+3.0.1
+-----
+
+* `Issue #157 <https://bitbucket.org/pypa/setuptools/issue/157>`_: Restore support for Python 2.6 in bootstrap script where
+  ``zipfile.ZipFile`` does not yet have support for context managers.
+
+---
+3.0
+---
+
+* `Issue #125 <https://bitbucket.org/pypa/setuptools/issue/125>`_: Prevent Subversion support from creating a ~/.subversion
+  directory just for checking the presence of a Subversion repository.
+* `Issue #12 <https://bitbucket.org/pypa/setuptools/issue/12>`_: Namespace packages are now imported lazily.  That is, the mere
+  declaration of a namespace package in an egg on ``sys.path`` no longer
+  causes it to be imported when ``pkg_resources`` is imported.  Note that this
+  change means that all of a namespace package's ``__init__.py`` files must
+  include a ``declare_namespace()`` call in order to ensure that they will be
+  handled properly at runtime.  In 2.x it was possible to get away without
+  including the declaration, but only at the cost of forcing namespace
+  packages to be imported early, which 3.0 no longer does.
+* `Issue #148 <https://bitbucket.org/pypa/setuptools/issue/148>`_: When building (bdist_egg), setuptools no longer adds
+  ``__init__.py`` files to namespace packages. Any packages that rely on this
+  behavior will need to create ``__init__.py`` files and include the
+  ``declare_namespace()``.
+* `Issue #7 <https://bitbucket.org/pypa/setuptools/issue/7>`_: Setuptools itself is now distributed as a zip archive in addition to
+  tar archive. ez_setup.py now uses zip archive. This approach avoids the potential
+  security vulnerabilities presented by use of tar archives in ez_setup.py.
+  It also leverages the security features added to ZipFile.extract in Python 2.7.4.
+* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Removed deprecated Features functionality.
+* `Pull Request #28 <https://bitbucket.org/pypa/setuptools/pull-request/28>`_: Remove backport of ``_bytecode_filenames`` which is
+  available in Python 2.6 and later, but also has better compatibility with
+  Python 3 environments.
+* `Issue #156 <https://bitbucket.org/pypa/setuptools/issue/156>`_: Fix spelling of __PYVENV_LAUNCHER__ variable.
+
+---
+2.2
+---
+
+* `Issue #141 <https://bitbucket.org/pypa/setuptools/issue/141>`_: Restored fix for allowing setup_requires dependencies to
+  override installed dependencies during setup.
+* `Issue #128 <https://bitbucket.org/pypa/setuptools/issue/128>`_: Fixed issue where only the first dependency link was honored
+  in a distribution where multiple dependency links were supplied.
+
+-----
+2.1.2
+-----
+
+* `Issue #144 <https://bitbucket.org/pypa/setuptools/issue/144>`_: Read long_description using codecs module to avoid errors
+  installing on systems where LANG=C.
+
+-----
+2.1.1
+-----
+
+* `Issue #139 <https://bitbucket.org/pypa/setuptools/issue/139>`_: Fix regression in re_finder for CVS repos (and maybe Git repos
+  as well).
+
+---
+2.1
+---
+
+* `Issue #129 <https://bitbucket.org/pypa/setuptools/issue/129>`_: Suppress inspection of ``*.whl`` files when searching for files
+  in a zip-imported file.
+* `Issue #131 <https://bitbucket.org/pypa/setuptools/issue/131>`_: Fix RuntimeError when constructing an egg fetcher.
+
+-----
+2.0.2
+-----
+
+* Fix NameError during installation with Python implementations (e.g. Jython)
+  not containing parser module.
+* Fix NameError in ``sdist:re_finder``.
+
+-----
+2.0.1
+-----
+
+* `Issue #124 <https://bitbucket.org/pypa/setuptools/issue/124>`_: Fixed error in list detection in upload_docs.
+
+---
+2.0
+---
+
+* `Issue #121 <https://bitbucket.org/pypa/setuptools/issue/121>`_: Exempt lib2to3 pickled grammars from DirectorySandbox.
+* `Issue #41 <https://bitbucket.org/pypa/setuptools/issue/41>`_: Dropped support for Python 2.4 and Python 2.5. Clients requiring
+  setuptools for those versions of Python should use setuptools 1.x.
+* Removed ``setuptools.command.easy_install.HAS_USER_SITE``. Clients
+  expecting this boolean variable should use ``site.ENABLE_USER_SITE``
+  instead.
+* Removed ``pkg_resources.ImpWrapper``. Clients that expected this class
+  should use ``pkgutil.ImpImporter`` instead.
+
+-----
+1.4.2
+-----
+
+* `Issue #116 <https://bitbucket.org/pypa/setuptools/issue/116>`_: Correct TypeError when reading a local package index on Python
+  3.
+
+-----
+1.4.1
+-----
+
+* `Issue #114 <https://bitbucket.org/pypa/setuptools/issue/114>`_: Use ``sys.getfilesystemencoding`` for decoding config in
+  ``bdist_wininst`` distributions.
+
+* `Issue #105 <https://bitbucket.org/pypa/setuptools/issue/105>`_ and `Issue #113 <https://bitbucket.org/pypa/setuptools/issue/113>`_: Establish a more robust technique for
+  determining the terminal encoding::
+
+    1. Try ``getpreferredencoding``
+    2. If that returns US_ASCII or None, try the encoding from
+       ``getdefaultlocale``. If that encoding was a "fallback" because Python
+       could not figure it out from the environment or OS, encoding remains
+       unresolved.
+    3. If the encoding is resolved, then make sure Python actually implements
+       the encoding.
+    4. On the event of an error or unknown codec, revert to fallbacks
+       (UTF-8 on Darwin, ASCII on everything else).
+    5. On the encoding is 'mac-roman' on Darwin, use UTF-8 as 'mac-roman' was
+       a bug on older Python releases.
+
+    On a side note, it would seem that the encoding only matters for when SVN
+    does not yet support ``--xml`` and when getting repository and svn version
+    numbers. The ``--xml`` technique should yield UTF-8 according to some
+    messages on the SVN mailing lists. So if the version numbers are always
+    7-bit ASCII clean, it may be best to only support the file parsing methods
+    for legacy SVN releases and support for SVN without the subprocess command
+    would simple go away as support for the older SVNs does.
+
+---
+1.4
+---
+
+* `Issue #27 <https://bitbucket.org/pypa/setuptools/issue/27>`_: ``easy_install`` will now use credentials from .pypirc if
+  present for connecting to the package index.
+* `Pull Request #21 <https://bitbucket.org/pypa/setuptools/pull-request/21>`_: Omit unwanted newlines in ``package_index._encode_auth``
+  when the username/password pair length indicates wrapping.
+
+-----
+1.3.2
+-----
+
+* `Issue #99 <https://bitbucket.org/pypa/setuptools/issue/99>`_: Fix filename encoding issues in SVN support.
+
+-----
+1.3.1
+-----
+
+* Remove exuberant warning in SVN support when SVN is not used.
+
+---
+1.3
+---
+
+* Address security vulnerability in SSL match_hostname check as reported in
+  `Python #17997 <http://bugs.python.org/issue17997>`_.
+* Prefer `backports.ssl_match_hostname
+  <https://pypi.python.org/pypi/backports.ssl_match_hostname>`_ for backport
+  implementation if present.
+* Correct NameError in ``ssl_support`` module (``socket.error``).
+
+---
+1.2
+---
+
+* `Issue #26 <https://bitbucket.org/pypa/setuptools/issue/26>`_: Add support for SVN 1.7. Special thanks to Philip Thiem for the
+  contribution.
+* `Issue #93 <https://bitbucket.org/pypa/setuptools/issue/93>`_: Wheels are now distributed with every release. Note that as
+  reported in `Issue #108 <https://bitbucket.org/pypa/setuptools/issue/108>`_, as of Pip 1.4, scripts aren't installed properly
+  from wheels. Therefore, if using Pip to install setuptools from a wheel,
+  the ``easy_install`` command will not be available.
+* Setuptools "natural" launcher support, introduced in 1.0, is now officially
+  supported.
+
+-----
+1.1.7
+-----
+
+* Fixed behavior of NameError handling in 'script template (dev).py' (script
+  launcher for 'develop' installs).
+* ``ez_setup.py`` now ensures partial downloads are cleaned up following
+  a failed download.
+* `Distribute #363 <https://bitbucket.org/tarek/distribute/issue/363>`_ and `Issue #55 <https://bitbucket.org/pypa/setuptools/issue/55>`_: Skip an sdist test that fails on locales
+  other than UTF-8.
+
+-----
+1.1.6
+-----
+
+* `Distribute #349 <https://bitbucket.org/tarek/distribute/issue/349>`_: ``sandbox.execfile`` now opens the target file in binary
+  mode, thus honoring a BOM in the file when compiled.
+
+-----
+1.1.5
+-----
+
+* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Second attempt at fix (logic was reversed).
+
+-----
+1.1.4
+-----
+
+* `Issue #77 <https://bitbucket.org/pypa/setuptools/issue/77>`_: Fix error in upload command (Python 2.4).

+1.1.2
+-----
+
+* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Correct issue where 404 errors are returned for URLs with

+1.1.1
+-----
+
+* `Issue #75 <https://bitbucket.org/pypa/setuptools/issue/75>`_: Add ``--insecure`` option to ez_setup.py to accommodate

+
+* `Issue #71 <https://bitbucket.org/pypa/setuptools/issue/71>`_ (`Distribute #333 <https://bitbucket.org/tarek/distribute/issue/333>`_): EasyInstall now puts less emphasis on the
+  condition when a host is blocked via ``--allow-hosts``.

+1.0

+
+* `Issue #60 <https://bitbucket.org/pypa/setuptools/issue/60>`_: On Windows, Setuptools supports deferring to another launcher,
+  such as Vinay Sajip's `pylauncher <https://bitbucket.org/pypa/pylauncher>`_
+  (included with Python 3.3) to launch console and GUI scripts and not install
+  its own launcher executables. This experimental functionality is currently
+  only enabled if  the ``SETUPTOOLS_LAUNCHER`` environment variable is set to
+  "natural". In the future, this behavior may become default, but only after
+  it has matured and seen substantial adoption. The ``SETUPTOOLS_LAUNCHER``
+  also accepts "executable" to force the default behavior of creating launcher
+  executables.
+* `Issue #63 <https://bitbucket.org/pypa/setuptools/issue/63>`_: Bootstrap script (ez_setup.py) now prefers Powershell, curl, or
+  wget for retrieving the Setuptools tarball for improved security of the
+  install. The script will still fall back to a simple ``urlopen`` on
+  platforms that do not have these tools.
+* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Deprecated the ``Features`` functionality.
+* `Issue #52 <https://bitbucket.org/pypa/setuptools/issue/52>`_: In ``VerifyingHTTPSConn``, handle a tunnelled (proxied)
+  connection.
+
+Backward-Incompatible Changes
+=============================
+
+This release includes a couple of backward-incompatible changes, but most if
+not all users will find 1.0 a drop-in replacement for 0.9.
+
+* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: Normalized API of environment marker support. Specifically,
+  removed line number and filename from SyntaxErrors when returned from
+  `pkg_resources.invalid_marker`. Any clients depending on the specific
+  string representation of exceptions returned by that function may need to
+  be updated to account for this change.
+* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: SyntaxErrors generated by `pkg_resources.invalid_marker` are
+  normalized for cross-implementation consistency.
+* Removed ``--ignore-conflicts-at-my-risk`` and ``--delete-conflicting``
+  options to easy_install. These options have been deprecated since 0.6a11.
+
+-----
+0.9.8
+-----
+
+* `Issue #53 <https://bitbucket.org/pypa/setuptools/issue/53>`_: Fix NameErrors in `_vcs_split_rev_from_url`.

+* `Issue #34 <https://bitbucket.org/pypa/setuptools/issue/34>`_: Documentation now refers to bootstrap script in code repository
+  referenced by bookmark.

+  conversion.
+

+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Yet another fix for yet another regression.
+

+  deprecated ``DISTRIBUTE_DISABLE_VERSIONED_EASY_INSTALL_SCRIPT``.
+
+-----
+0.7.4
+-----
+
+* `Issue #20 <https://bitbucket.org/pypa/setuptools/issue/20>`_: Fix comparison of parsed SVN version on Python 3.
+
+-----
+0.7.3
+-----
+
+* `Issue #1 <https://bitbucket.org/pypa/setuptools/issue/1>`_: Disable installation of Windows-specific files on non-Windows systems.

+
+---
+0.7
+---
+
+* Merged Setuptools and Distribute. See docs/merge.txt for details.
+
+Added several features that were slated for setuptools 0.6c12:
+
+* Index URL now defaults to HTTPS.
+* Added experimental environment marker support. Now clients may designate a
+  PEP-426 environment marker for "extra" dependencies. Setuptools uses this
+  feature in ``setup.py`` for optional SSL and certificate validation support
+  on older platforms. Based on Distutils-SIG discussions, the syntax is
+  somewhat tentative. There should probably be a PEP with a firmer spec before
+  the feature should be considered suitable for use.
+* Added support for SSL certificate validation when installing packages from
+  an HTTPS service.
+
+-----
+0.7b4
+-----
+
+* `Issue #3 <https://bitbucket.org/pypa/setuptools/issue/3>`_: Fixed NameError in SSL support.
+
+------
+0.6.49
+------
+
+* Move warning check in ``get_cache_path`` to follow the directory creation
+  to avoid errors when the cache path does not yet exist. Fixes the error
+  reported in `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_.
+
+------
+0.6.48
+------
+
+* Correct AttributeError in ``ResourceManager.get_cache_path`` introduced in
+  0.6.46 (redo).
+
+------
+0.6.47
+------
+
+* Correct AttributeError in ``ResourceManager.get_cache_path`` introduced in
+  0.6.46.
+
+------
+0.6.46
+------
+
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Issue a warning if the PYTHON_EGG_CACHE or otherwise
+  customized egg cache location specifies a directory that's group- or
+  world-writable.
+
+------
+0.6.45
+------
+
+* `Distribute #379 <https://bitbucket.org/tarek/distribute/issue/379>`_: ``distribute_setup.py`` now traps VersionConflict as well,
+  restoring ability to upgrade from an older setuptools version.

+------
+
+* `Distribute #378 <https://bitbucket.org/tarek/distribute/issue/378>`_: Restore support for Python 2.4 Syntax (regression in 0.6.42).
+
+------
+0.6.42
+------
+
+* External links finder no longer yields duplicate links.
+* `Distribute #337 <https://bitbucket.org/tarek/distribute/issue/337>`_: Moved site.py to setuptools/site-patch.py (graft of very old
+  patch from setuptools trunk which inspired PR `#31 <https://bitbucket.org/pypa/setuptools/issue/31>`_).
+
+------
+0.6.41
+------
+
+* `Distribute #27 <https://bitbucket.org/tarek/distribute/issue/27>`_: Use public api for loading resources from zip files rather than
+  the private method `_zip_directory_cache`.
+* Added a new function ``easy_install.get_win_launcher`` which may be used by
+  third-party libraries such as buildout to get a suitable script launcher.
+
+------
+0.6.40
+------
+
+* `Distribute #376 <https://bitbucket.org/tarek/distribute/issue/376>`_: brought back cli.exe and gui.exe that were deleted in the
+  previous release.
+
+------
+0.6.39
+------
+
+* Add support for console launchers on ARM platforms.
+* Fix possible issue in GUI launchers where the subsystem was not supplied to
+  the linker.
+* Launcher build script now refactored for robustness.

+  check the contents of the file against the zip contents during each
+  invocation of get_resource_filename.
+
+------
+0.6.38
+------
+
+* `Distribute #371 <https://bitbucket.org/tarek/distribute/issue/371>`_: The launcher manifest file is now installed properly.
+
+------
+0.6.37
+------
+
+* `Distribute #143 <https://bitbucket.org/tarek/distribute/issue/143>`_: Launcher scripts, including easy_install itself, are now
+  accompanied by a manifest on 32-bit Windows environments to avoid the
+  Installer Detection Technology and thus undesirable UAC elevation described
+  in `this Microsoft article
+  <http://technet.microsoft.com/en-us/library/cc709628%28WS.10%29.aspx>`_.
+
+------
+0.6.36
+------
+
+* `Pull Request #35 <https://bitbucket.org/pypa/setuptools/pull-request/35>`_: In `Buildout #64 <https://github.com/buildout/buildout/issues/64>`_, it was reported that
+  under Python 3, installation of distutils scripts could attempt to copy
+  the ``__pycache__`` directory as a file, causing an error, apparently only
+  under Windows. Easy_install now skips all directories when processing
+  metadata scripts.
+
+------
+0.6.35
+------
+
+
+Note this release is backward-incompatible with distribute 0.6.23-0.6.34 in
+how it parses version numbers.
+
+* `Distribute #278 <https://bitbucket.org/tarek/distribute/issue/278>`_: Restored compatibility with distribute 0.6.22 and setuptools

+0.6.34
+------
+
+* `Distribute #341 <https://bitbucket.org/tarek/distribute/issue/341>`_: 0.6.33 fails to build under Python 2.4.

+* Fix 1 failure with Jython 2.5 and 2.7.
+* Disable workaround for Jython scripts on Linux systems.
+* `Distribute #336 <https://bitbucket.org/tarek/distribute/issue/336>`_: `setup.py` no longer masks failure exit code when tests fail.
+* Fix issue in pkg_resources where try/except around a platform-dependent
+  import would trigger hook load failures on Mercurial. See pull request 32
+  for details.
+* `Distribute #341 <https://bitbucket.org/tarek/distribute/issue/341>`_: Fix a ResourceWarning.
+
+------

+  Jython.
+* Work around `Jython #1980 <http://bugs.jython.org/issue1980>`_ and `Jython #1981 <http://bugs.jython.org/issue1981>`_.
+* `Distribute #334 <https://bitbucket.org/tarek/distribute/issue/334>`_: Provide workaround for packages that reference `sys.__stdout__`
+  such as numpy does. This change should address
+  `virtualenv `#359 <https://bitbucket.org/pypa/setuptools/issue/359>`_ <https://github.com/pypa/virtualenv/issues/359>`_ as long
+  as the system encoding is UTF-8 or the IO encoding is specified in the
+  environment, i.e.::
+
+     PYTHONIOENCODING=utf8 pip install numpy
+
+* Fix for encoding issue when installing from Windows executable on Python 3.
+* `Distribute #323 <https://bitbucket.org/tarek/distribute/issue/323>`_: Allow `setup_requires` requirements to supercede installed
+  requirements. Added some new keyword arguments to existing pkg_resources
+  methods. Also had to updated how __path__ is handled for namespace packages
+  to ensure that when a new egg distribution containing a namespace package is
+  placed on sys.path, the entries in __path__ are found in the same order they
+  would have been in had that egg been on the path when pkg_resources was
+  first imported.
+
+------
+0.6.30
+------
+
+* `Distribute #328 <https://bitbucket.org/tarek/distribute/issue/328>`_: Clean up temporary directories in distribute_setup.py.
+* Fix fatal bug in distribute_setup.py.

+* `Distribute #327 <https://bitbucket.org/tarek/distribute/issue/327>`_: Merged pull request `#24 <https://bitbucket.org/pypa/setuptools/issue/24>`_ to fix a dependency problem with pip.
+* Merged pull request `#23 <https://bitbucket.org/pypa/setuptools/issue/23>`_ to fix https://github.com/pypa/virtualenv/issues/301.
+* If Sphinx is installed, the `upload_docs` command now runs `build_sphinx`
+  to produce uploadable documentation.
+* `Distribute #326 <https://bitbucket.org/tarek/distribute/issue/326>`_: `upload_docs` provided mangled auth credentials under Python 3.
+* `Distribute #320 <https://bitbucket.org/tarek/distribute/issue/320>`_: Fix check for "createable" in distribute_setup.py.
+* `Distribute #305 <https://bitbucket.org/tarek/distribute/issue/305>`_: Remove a warning that was triggered during normal operations.
+* `Distribute #311 <https://bitbucket.org/tarek/distribute/issue/311>`_: Print metadata in UTF-8 independent of platform.
+* `Distribute #303 <https://bitbucket.org/tarek/distribute/issue/303>`_: Read manifest file with UTF-8 encoding under Python 3.

+* `Distribute #283 <https://bitbucket.org/tarek/distribute/issue/283>`_: Reenable scanning of `*.pyc` / `*.pyo` files on Python 3.3.
+* `Distribute #299 <https://bitbucket.org/tarek/distribute/issue/299>`_: The develop command didn't work on Python 3, when using 2to3,
+  as the egg link would go to the Python 2 source. Linking to the 2to3'd code
+  in build/lib makes it work, although you will have to rebuild the module
+  before testing it.
+* `Distribute #306 <https://bitbucket.org/tarek/distribute/issue/306>`_: Even if 2to3 is used, we build in-place under Python 2.
+* `Distribute #307 <https://bitbucket.org/tarek/distribute/issue/307>`_: Prints the full path when .svn/entries is broken.
+* `Distribute #313 <https://bitbucket.org/tarek/distribute/issue/313>`_: Support for sdist subcommands (Python 2.7)
+* `Distribute #314 <https://bitbucket.org/tarek/distribute/issue/314>`_: test_local_index() would fail an OS X.
+* `Distribute #310 <https://bitbucket.org/tarek/distribute/issue/310>`_: Non-ascii characters in a namespace __init__.py causes errors.
+* `Distribute #218 <https://bitbucket.org/tarek/distribute/issue/218>`_: Improved documentation on behavior of `package_data` and

+  on late releases of Python.
+* `Distribute #272 <https://bitbucket.org/tarek/distribute/issue/272>`_: Prevent TypeError when namespace package names are unicode

+------
+0.6.10
+------
+
+* Reverted change made for the DistributionNotFound exception because

+0.6.9
+-----
+
+* `Distribute #90 <https://bitbucket.org/tarek/distribute/issue/90>`_: unknown setuptools version can be added in the working set

+  (install, develop, etc).
+* `Distribute #101 <https://bitbucket.org/tarek/distribute/issue/101>`_: Allowing ``os.devnull`` in Sandbox
+* `Distribute #92 <https://bitbucket.org/tarek/distribute/issue/92>`_: Fixed the "no eggs" found error with MacPort

+* `Distribute #58 <https://bitbucket.org/tarek/distribute/issue/58>`_: Added --user support to the develop command
+* `Distribute #11 <https://bitbucket.org/tarek/distribute/issue/11>`_: Generated scripts now wrap their call to the script entry point
+  in the standard "if name == 'main'"
+* Added the 'DONT_PATCH_SETUPTOOLS' environment variable, so virtualenv
+  can drive an installation that doesn't patch a global setuptools.
+* Reviewed unladen-swallow specific change from
+  http://code.google.com/p/unladen-swallow/source/detail?spec=svn875&r=719
+  and determined that it no longer applies. Distribute should work fine with
+  Unladen Swallow 2009Q3.
+* `Distribute #21 <https://bitbucket.org/tarek/distribute/issue/21>`_: Allow PackageIndex.open_url to gracefully handle all cases of a
+  httplib.HTTPException instead of just InvalidURL and BadStatusLine.
+* Removed virtual-python.py from this distribution and updated documentation
+  to point to the actively maintained virtualenv instead.
+* `Distribute #64 <https://bitbucket.org/tarek/distribute/issue/64>`_: use_setuptools no longer rebuilds the distribute egg every
+  time it is run
+* use_setuptools now properly respects the requested version
+* use_setuptools will no longer try to import a distribute egg for the
+  wrong Python version
+* `Distribute #74 <https://bitbucket.org/tarek/distribute/issue/74>`_: no_fake should be True by default.
+* `Distribute #72 <https://bitbucket.org/tarek/distribute/issue/72>`_: avoid a bootstrapping issue with easy_install -U
+
+-----
+0.6.6

+
+* Unified the bootstrap file so it works on both py2.x and py3k without 2to3
+  (patch by Holger Krekel)
+
+-----
+0.6.5
+-----
+
+* `Distribute #65 <https://bitbucket.org/tarek/distribute/issue/65>`_: cli.exe and gui.exe are now generated at build time,
+  depending on the platform in use.
+
+* `Distribute #67 <https://bitbucket.org/tarek/distribute/issue/67>`_: Fixed doc typo (PEP 381/382)
+
+* Distribute no longer shadows setuptools if we require a 0.7-series
+  setuptools.  And an error is raised when installing a 0.7 setuptools with
+  distribute.
+
+* When run from within buildout, no attempt is made to modify an existing
+  setuptools egg, whether in a shared egg directory or a system setuptools.
+
+* Fixed a hole in sandboxing allowing builtin file to write outside of
+  the sandbox.
+
+-----
+0.6.4

+
+-----
+0.6c9
+-----
+
+ * Fixed a missing files problem when using Windows source distributions on
+   non-Windows platforms, due to distutils not handling manifest file line
+   endings correctly.
+
+ * Updated Pyrex support to work with Pyrex 0.9.6 and higher.
+
+ * Minor changes for Jython compatibility, including skipping tests that can't
+   work on Jython.
+
+ * Fixed not installing eggs in ``install_requires`` if they were also used for
+   ``setup_requires`` or ``tests_require``.
+
+ * Fixed not fetching eggs in ``install_requires`` when running tests.
+
+ * Allow ``ez_setup.use_setuptools()`` to upgrade existing setuptools
+   installations when called from a standalone ``setup.py``.
+
+ * Added a warning if a namespace package is declared, but its parent package
+   is not also declared as a namespace.
+
+ * Support Subversion 1.5
+
+ * Removed use of deprecated ``md5`` module if ``hashlib`` is available
+
+ * Fixed ``bdist_wininst upload`` trying to upload the ``.exe`` twice
+
+ * Fixed ``bdist_egg`` putting a ``native_libs.txt`` in the source package's
+   ``.egg-info``, when it should only be in the built egg's ``EGG-INFO``.
+
+ * Ensure that _full_name is set on all shared libs before extensions are
+   checked for shared lib usage.  (Fixes a bug in the experimental shared
+   library build support.)
+
+ * Fix to allow unpacked eggs containing native libraries to fail more
+   gracefully under Google App Engine (with an ``ImportError`` loading the
+   C-based module, instead of getting a ``NameError``).
+
+-----
+0.6c7
+-----
+
+ * Fixed ``distutils.filelist.findall()`` crashing on broken symlinks, and
+   ``egg_info`` command failing on new, uncommitted SVN directories.
+
+ * Fix import problems with nested namespace packages installed via
+   ``--root`` or ``--single-version-externally-managed``, due to the
+   parent package not having the child package as an attribute.
+
+-----
+0.6c6
+-----
+
+ * Added ``--egg-path`` option to ``develop`` command, allowing you to force
+   ``.egg-link`` files to use relative paths (allowing them to be shared across
+   platforms on a networked drive).
+
+ * Fix not building binary RPMs correctly.
+
+ * Fix "eggsecutables" (such as setuptools' own egg) only being runnable with
+   bash-compatible shells.
+
+ * Fix ``#!`` parsing problems in Windows ``.exe`` script wrappers, when there
+   was whitespace inside a quoted argument or at the end of the ``#!`` line
+   (a regression introduced in 0.6c4).
+
+ * Fix ``test`` command possibly failing if an older version of the project
+   being tested was installed on ``sys.path`` ahead of the test source
+   directory.
+
+ * Fix ``find_packages()`` treating ``ez_setup`` and directories with ``.`` in
+   their names as packages.
+
+-----
+0.6c5
+-----
+
+ * Fix uploaded ``bdist_rpm`` packages being described as ``bdist_egg``
+   packages under Python versions less than 2.5.
+
+ * Fix uploaded ``bdist_wininst`` packages being described as suitable for
+   "any" version by Python 2.5, even if a ``--target-version`` was specified.
+
+-----
+0.6c4
+-----
+
+ * Overhauled Windows script wrapping to support ``bdist_wininst`` better.
+   Scripts installed with ``bdist_wininst`` will always use ``#!python.exe`` or
+   ``#!pythonw.exe`` as the executable name (even when built on non-Windows
+   platforms!), and the wrappers will look for the executable in the script's
+   parent directory (which should find the right version of Python).
+
+ * Fix ``upload`` command not uploading files built by ``bdist_rpm`` or
+   ``bdist_wininst`` under Python 2.3 and 2.4.
+
+ * Add support for "eggsecutable" headers: a ``#!/bin/sh`` script that is
+   prepended to an ``.egg`` file to allow it to be run as a script on Unix-ish
+   platforms.  (This is mainly so that setuptools itself can have a single-file
+   installer on Unix, without doing multiple downloads, dealing with firewalls,
+   etc.)
+
+ * Fix problem with empty revision numbers in Subversion 1.4 ``entries`` files
+
+ * Use cross-platform relative paths in ``easy-install.pth`` when doing
+   ``develop`` and the source directory is a subdirectory of the installation
+   target directory.
+
+ * Fix a problem installing eggs with a system packaging tool if the project
+   contained an implicit namespace package; for example if the ``setup()``
+   listed a namespace package ``foo.bar`` without explicitly listing ``foo``
+   as a namespace package.
+
+-----
+0.6c3
+-----
+
+ * Fixed breakages caused by Subversion 1.4's new "working copy" format
+
+-----
+0.6c2
+-----
+
+ * The ``ez_setup`` module displays the conflicting version of setuptools (and
+   its installation location) when a script requests a version that's not
+   available.
+
+ * Running ``setup.py develop`` on a setuptools-using project will now install
+   setuptools if needed, instead of only downloading the egg.
+
+-----
+0.6c1
+-----
+
+ * Fixed ``AttributeError`` when trying to download a ``setup_requires``
+   dependency when a distribution lacks a ``dependency_links`` setting.
+
+ * Made ``zip-safe`` and ``not-zip-safe`` flag files contain a single byte, so
+   as to play better with packaging tools that complain about zero-length
+   files.
+
+ * Made ``setup.py develop`` respect the ``--no-deps`` option, which it
+   previously was ignoring.
+
+ * Support ``extra_path`` option to ``setup()`` when ``install`` is run in
+   backward-compatibility mode.
+
+ * Source distributions now always include a ``setup.cfg`` file that explicitly
+   sets ``egg_info`` options such that they produce an identical version number
+   to the source distribution's version number.  (Previously, the default
+   version number could be different due to the use of ``--tag-date``, or if
+   the version was overridden on the command line that built the source
+   distribution.)
+
+-----
+0.6b4
+-----
+
+ * Fix ``register`` not obeying name/version set by ``egg_info`` command, if
+   ``egg_info`` wasn't explicitly run first on the same command line.
+
+ * Added ``--no-date`` and ``--no-svn-revision`` options to ``egg_info``
+   command, to allow suppressing tags configured in ``setup.cfg``.
+
+ * Fixed redundant warnings about missing ``README`` file(s); it should now
+   appear only if you are actually a source distribution.
+
+-----
+0.6b3
+-----
+
+ * Fix ``bdist_egg`` not including files in subdirectories of ``.egg-info``.
+
+ * Allow ``.py`` files found by the ``include_package_data`` option to be
+   automatically included.  Remove duplicate data file matches if both
+   ``include_package_data`` and ``package_data`` are used to refer to the same
+   files.
+
+-----
+0.6b1
+-----
+
+ * Strip ``module`` from the end of compiled extension modules when computing
+   the name of a ``.py`` loader/wrapper.  (Python's import machinery ignores
+   this suffix when searching for an extension module.)
+
+------
+0.6a11
+------
+
+ * Added ``test_loader`` keyword to support custom test loaders
+
+ * Added ``setuptools.file_finders`` entry point group to allow implementing
+   revision control plugins.
+
+ * Added ``--identity`` option to ``upload`` command.
+
+ * Added ``dependency_links`` to allow specifying URLs for ``--find-links``.
+
+ * Enhanced test loader to scan packages as well as modules, and call
+   ``additional_tests()`` if present to get non-unittest tests.
+
+ * Support namespace packages in conjunction with system packagers, by omitting
+   the installation of any ``__init__.py`` files for namespace packages, and
+   adding a special ``.pth`` file to create a working package in
+   ``sys.modules``.
+
+ * Made ``--single-version-externally-managed`` automatic when ``--root`` is
+   used, so that most system packagers won't require special support for
+   setuptools.
+
+ * Fixed ``setup_requires``, ``tests_require``, etc. not using ``setup.cfg`` or
+   other configuration files for their option defaults when installing, and
+   also made the install use ``--multi-version`` mode so that the project
+   directory doesn't need to support .pth files.
+
+ * ``MANIFEST.in`` is now forcibly closed when any errors occur while reading
+   it.  Previously, the file could be left open and the actual error would be
+   masked by problems trying to remove the open file on Windows systems.
+
+------
+0.6a10
+------
+
+ * Fixed the ``develop`` command ignoring ``--find-links``.
+
+-----
+0.6a9
+-----
+
+ * The ``sdist`` command no longer uses the traditional ``MANIFEST`` file to
+   create source distributions.  ``MANIFEST.in`` is still read and processed,
+   as are the standard defaults and pruning.  But the manifest is built inside
+   the project's ``.egg-info`` directory as ``SOURCES.txt``, and it is rebuilt
+   every time the ``egg_info`` command is run.
+
+ * Added the ``include_package_data`` keyword to ``setup()``, allowing you to
+   automatically include any package data listed in revision control or
+   ``MANIFEST.in``
+
+ * Added the ``exclude_package_data`` keyword to ``setup()``, allowing you to
+   trim back files included via the ``package_data`` and
+   ``include_package_data`` options.
+
+ * Fixed ``--tag-svn-revision`` not working when run from a source
+   distribution.
+
+ * Added warning for namespace packages with missing ``declare_namespace()``
+
+ * Added ``tests_require`` keyword to ``setup()``, so that e.g. packages
+   requiring ``nose`` to run unit tests can make this dependency optional
+   unless the ``test`` command is run.
+
+ * Made all commands that use ``easy_install`` respect its configuration
+   options, as this was causing some problems with ``setup.py install``.
+
+ * Added an ``unpack_directory()`` driver to ``setuptools.archive_util``, so
+   that you can process a directory tree through a processing filter as if it
+   were a zipfile or tarfile.
+
+ * Added an internal ``install_egg_info`` command to use as part of old-style
+   ``install`` operations, that installs an ``.egg-info`` directory with the
+   package.
+
+ * Added a ``--single-version-externally-managed`` option to the ``install``
+   command so that you can more easily wrap a "flat" egg in a system package.
+
+ * Enhanced ``bdist_rpm`` so that it installs single-version eggs that
+   don't rely on a ``.pth`` file.  The ``--no-egg`` option has been removed,
+   since all RPMs are now built in a more backwards-compatible format.
+
+ * Support full roundtrip translation of eggs to and from ``bdist_wininst``
+   format.  Running ``bdist_wininst`` on a setuptools-based package wraps the
+   egg in an .exe that will safely install it as an egg (i.e., with metadata
+   and entry-point wrapper scripts), and ``easy_install`` can turn the .exe
+   back into an ``.egg`` file or directory and install it as such.
+
+
+-----
+0.6a8
+-----
+
+ * Fixed some problems building extensions when Pyrex was installed, especially
+   with Python 2.4 and/or packages using SWIG.
+
+ * Made ``develop`` command accept all the same options as ``easy_install``,
+   and use the ``easy_install`` command's configuration settings as defaults.
+
+ * Made ``egg_info --tag-svn-revision`` fall back to extracting the revision
+   number from ``PKG-INFO`` in case it is being run on a source distribution of
+   a snapshot taken from a Subversion-based project.
+
+ * Automatically detect ``.dll``, ``.so`` and ``.dylib`` files that are being
+   installed as data, adding them to ``native_libs.txt`` automatically.
+
+ * Fixed some problems with fresh checkouts of projects that don't include
+   ``.egg-info/PKG-INFO`` under revision control and put the project's source
+   code directly in the project directory.  If such a package had any
+   requirements that get processed before the ``egg_info`` command can be run,
+   the setup scripts would fail with a "Missing 'Version:' header and/or
+   PKG-INFO file" error, because the egg runtime interpreted the unbuilt
+   metadata in a directory on ``sys.path`` (i.e. the current directory) as
+   being a corrupted egg.  Setuptools now monkeypatches the distribution
+   metadata cache to pretend that the egg has valid version information, until
+   it has a chance to make it actually be so (via the ``egg_info`` command).
+
+-----
+0.6a5
+-----
+
+ * Fixed missing gui/cli .exe files in distribution.  Fixed bugs in tests.
+
+-----
+0.6a3
+-----
+
+ * Added ``gui_scripts`` entry point group to allow installing GUI scripts
+   on Windows and other platforms.  (The special handling is only for Windows;
+   other platforms are treated the same as for ``console_scripts``.)
+
+-----
+0.6a2
+-----
+
+ * Added ``console_scripts`` entry point group to allow installing scripts
+   without the need to create separate script files.  On Windows, console
+   scripts get an ``.exe`` wrapper so you can just type their name.  On other
+   platforms, the scripts are written without a file extension.
+
+-----
+0.6a1
+-----
+
+ * Added support for building "old-style" RPMs that don't install an egg for
+   the target package, using a ``--no-egg`` option.
+
+ * The ``build_ext`` command now works better when using the ``--inplace``
+   option and multiple Python versions.  It now makes sure that all extensions
+   match the current Python version, even if newer copies were built for a
+   different Python version.
+
+ * The ``upload`` command no longer attaches an extra ``.zip`` when uploading
+   eggs, as PyPI now supports egg uploads without trickery.
+
+ * The ``ez_setup`` script/module now displays a warning before downloading
+   the setuptools egg, and attempts to check the downloaded egg against an
+   internal MD5 checksum table.
+
+ * Fixed the ``--tag-svn-revision`` option of ``egg_info`` not finding the
+   latest revision number; it was using the revision number of the directory
+   containing ``setup.py``, not the highest revision number in the project.
+
+ * Added ``eager_resources`` setup argument
+
+ * The ``sdist`` command now recognizes Subversion "deleted file" entries and
+   does not include them in source distributions.
+
+ * ``setuptools`` now embeds itself more thoroughly into the distutils, so that
+   other distutils extensions (e.g. py2exe, py2app) will subclass setuptools'
+   versions of things, rather than the native distutils ones.
+
+ * Added ``entry_points`` and ``setup_requires`` arguments to ``setup()``;
+   ``setup_requires`` allows you to automatically find and download packages
+   that are needed in order to *build* your project (as opposed to running it).
+
+ * ``setuptools`` now finds its commands, ``setup()`` argument validators, and
+   metadata writers using entry points, so that they can be extended by
+   third-party packages.  See `Creating distutils Extensions
+   <http://pythonhosted.org/setuptools/setuptools.html#creating-distutils-extensions>`_
+   for more details.
+
+ * The vestigial ``depends`` command has been removed.  It was never finished
+   or documented, and never would have worked without EasyInstall - which it
+   pre-dated and was never compatible with.
+
+------
+0.5a12
+------
+
+ * The zip-safety scanner now checks for modules that might be used with
+   ``python -m``, and marks them as unsafe for zipping, since Python 2.4 can't
+   handle ``-m`` on zipped modules.
+
+------
+0.5a11
+------
+
+ * Fix breakage of the "develop" command that was caused by the addition of
+   ``--always-unzip`` to the ``easy_install`` command.
+
+-----
+0.5a9
+-----
+
+ * Include ``svn:externals`` directories in source distributions as well as
+   normal subversion-controlled files and directories.
+
+ * Added ``exclude=patternlist`` option to ``setuptools.find_packages()``
+
+ * Changed --tag-svn-revision to include an "r" in front of the revision number
+   for better readability.
+
+ * Added ability to build eggs without including source files (except for any
+   scripts, of course), using the ``--exclude-source-files`` option to
+   ``bdist_egg``.
+
+ * ``setup.py install`` now automatically detects when an "unmanaged" package
+   or module is going to be on ``sys.path`` ahead of a package being installed,
+   thereby preventing the newer version from being imported.  If this occurs,
+   a warning message is output to ``sys.stderr``, but installation proceeds
+   anyway.  The warning message informs the user what files or directories
+   need deleting, and advises them they can also use EasyInstall (with the
+   ``--delete-conflicting`` option) to do it automatically.
+
+ * The ``egg_info`` command now adds a ``top_level.txt`` file to the metadata
+   directory that lists all top-level modules and packages in the distribution.
+   This is used by the ``easy_install`` command to find possibly-conflicting
+   "unmanaged" packages when installing the distribution.
+
+ * Added ``zip_safe`` and ``namespace_packages`` arguments to ``setup()``.
+   Added package analysis to determine zip-safety if the ``zip_safe`` flag
+   is not given, and advise the author regarding what code might need changing.
+
+ * Fixed the swapped ``-d`` and ``-b`` options of ``bdist_egg``.
+
+-----
+0.5a8
+-----
+
+ * The "egg_info" command now always sets the distribution metadata to "safe"
+   forms of the distribution name and version, so that distribution files will
+   be generated with parseable names (i.e., ones that don't include '-' in the
+   name or version).  Also, this means that if you use the various ``--tag``
+   options of "egg_info", any distributions generated will use the tags in the
+   version, not just egg distributions.
+
+ * Added support for defining command aliases in distutils configuration files,
+   under the "[aliases]" section.  To prevent recursion and to allow aliases to
+   call the command of the same name, a given alias can be expanded only once
+   per command-line invocation.  You can define new aliases with the "alias"
+   command, either for the local, global, or per-user configuration.
+
+ * Added "rotate" command to delete old distribution files, given a set of
+   patterns to match and the number of files to keep.  (Keeps the most
+   recently-modified distribution files matching each pattern.)
+
+ * Added "saveopts" command that saves all command-line options for the current
+   invocation to the local, global, or per-user configuration file.  Useful for
+   setting defaults without having to hand-edit a configuration file.
+
+ * Added a "setopt" command that sets a single option in a specified distutils
+   configuration file.
+
+-----
+0.5a7
+-----
+
+ * Added "upload" support for egg and source distributions, including a bug
+   fix for "upload" and a temporary workaround for lack of .egg support in
+   PyPI.
+
+-----
+0.5a6
+-----
+
+ * Beefed up the "sdist" command so that if you don't have a MANIFEST.in, it
+   will include all files under revision control (CVS or Subversion) in the
+   current directory, and it will regenerate the list every time you create a
+   source distribution, not just when you tell it to.  This should make the
+   default "do what you mean" more often than the distutils' default behavior
+   did, while still retaining the old behavior in the presence of MANIFEST.in.
+
+ * Fixed the "develop" command always updating .pth files, even if you
+   specified ``-n`` or ``--dry-run``.
+
+ * Slightly changed the format of the generated version when you use
+   ``--tag-build`` on the "egg_info" command, so that you can make tagged
+   revisions compare *lower* than the version specified in setup.py (e.g. by
+   using ``--tag-build=dev``).
+
+-----
+0.5a5
+-----
+
+ * Added ``develop`` command to ``setuptools``-based packages.  This command
+   installs an ``.egg-link`` pointing to the package's source directory, and
+   script wrappers that ``execfile()`` the source versions of the package's
+   scripts.  This lets you put your development checkout(s) on sys.path without
+   having to actually install them.  (To uninstall the link, use
+   use ``setup.py develop --uninstall``.)
+
+ * Added ``egg_info`` command to ``setuptools``-based packages.  This command
+   just creates or updates the "projectname.egg-info" directory, without
+   building an egg.  (It's used by the ``bdist_egg``, ``test``, and ``develop``
+   commands.)
+
+ * Enhanced the ``test`` command so that it doesn't install the package, but
+   instead builds any C extensions in-place, updates the ``.egg-info``
+   metadata, adds the source directory to ``sys.path``, and runs the tests
+   directly on the source.  This avoids an "unmanaged" installation of the
+   package to ``site-packages`` or elsewhere.
+
+ * Made ``easy_install`` a standard ``setuptools`` command, moving it from
+   the ``easy_install`` module to ``setuptools.command.easy_install``.  Note
+   that if you were importing or extending it, you must now change your imports
+   accordingly.  ``easy_install.py`` is still installed as a script, but not as
+   a module.
+
+-----
+0.5a4
+-----
+
+ * Setup scripts using setuptools can now list their dependencies directly in
+   the setup.py file, without having to manually create a ``depends.txt`` file.
+   The ``install_requires`` and ``extras_require`` arguments to ``setup()``
+   are used to create a dependencies file automatically.  If you are manually
+   creating ``depends.txt`` right now, please switch to using these setup
+   arguments as soon as practical, because ``depends.txt`` support will be
+   removed in the 0.6 release cycle.  For documentation on the new arguments,
+   see the ``setuptools.dist.Distribution`` class.
+
+ * Setup scripts using setuptools now always install using ``easy_install``
+   internally, for ease of uninstallation and upgrading.
+
+-----
+0.5a1
+-----
+
+ * Added support for "self-installation" bootstrapping.  Packages can now
+   include ``ez_setup.py`` in their source distribution, and add the following
+   to their ``setup.py``, in order to automatically bootstrap installation of
+   setuptools as part of their setup process::
+
+    from ez_setup import use_setuptools
+    use_setuptools()
+
+    from setuptools import setup
+    # etc...
+
+-----
+0.4a2
+-----
+
+ * Added ``ez_setup.py`` installer/bootstrap script to make initial setuptools
+   installation easier, and to allow distributions using setuptools to avoid
+   having to include setuptools in their source distribution.
+
+ * All downloads are now managed by the ``PackageIndex`` class (which is now
+   subclassable and replaceable), so that embedders can more easily override
+   download logic, give download progress reports, etc.  The class has also
+   been moved to the new ``setuptools.package_index`` module.
+
+ * The ``Installer`` class no longer handles downloading, manages a temporary
+   directory, or tracks the ``zip_ok`` option.  Downloading is now handled
+   by ``PackageIndex``, and ``Installer`` has become an ``easy_install``
+   command class based on ``setuptools.Command``.
+
+ * There is a new ``setuptools.sandbox.run_setup()`` API to invoke a setup
+   script in a directory sandbox, and a new ``setuptools.archive_util`` module
+   with an ``unpack_archive()`` API.  These were split out of EasyInstall to
+   allow reuse by other tools and applications.
+
+ * ``setuptools.Command`` now supports reinitializing commands using keyword
+   arguments to set/reset options.  Also, ``Command`` subclasses can now set
+   their ``command_consumes_arguments`` attribute to ``True`` in order to
+   receive an ``args`` option containing the rest of the command line.
+
+-----
+0.3a2
+-----
+
+ * Added new options to ``bdist_egg`` to allow tagging the egg's version number
+   with a subversion revision number, the current date, or an explicit tag
+   value.  Run ``setup.py bdist_egg --help`` to get more information.
+
+ * Misc. bug fixes
+
+-----
+0.3a1
+-----
+
+ * Initial release.

+===============================
+Installing and Using Setuptools
+===============================
+
+.. contents:: **Table of Contents**
+
+
+-------------------------
+Installation Instructions
+-------------------------
+
+The recommended way to bootstrap setuptools on any system is to download
+`ez_setup.py`_ and run it using the target Python environment. Different
+operating systems have different recommended techniques to accomplish this
+basic routine, so below are some examples to get you started.
+
+Setuptools requires Python 2.6 or later. To install setuptools
+on Python 2.4 or Python 2.5, use the `bootstrap script for Setuptools 1.x
+<https://bitbucket.org/pypa/setuptools/raw/bootstrap-py24/ez_setup.py>`_.
+
+The link provided to ez_setup.py is a bookmark to bootstrap script for the
+latest known stable release.
+
+.. _ez_setup.py: https://bootstrap.pypa.io/ez_setup.py
+
+Windows (Powershell 3 or later)
+===============================
+
+For best results, uninstall previous versions FIRST (see `Uninstalling`_).
+
+Using Windows 8 (which includes PowerShell 3) or earlier versions of Windows
+with PowerShell 3 installed, it's possible to install with one simple
+Powershell command. Start up Powershell and paste this command::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python -
+
+You must start the Powershell with Administrative privileges or you may choose
+to install a user-local installation::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python - --user
+
+If you have Python 3.3 or later, you can use the ``py`` command to install to
+different Python versions. For example, to install to Python 3.3 if you have
+Python 2.7 installed::
+
+    > (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | py -3 -
+
+The recommended way to install setuptools on Windows is to download
+`ez_setup.py`_ and run it. The script will download the appropriate
+distribution file and install it for you.
+
+Once installation is complete, you will find an ``easy_install`` program in
+your Python ``Scripts`` subdirectory.  For simple invocation and best results,
+add this directory to your ``PATH`` environment variable, if it is not already
+present. If you did a user-local install, the ``Scripts`` subdirectory is
+``$env:APPDATA\Python\Scripts``.
+
+
+Windows (simplified)
+====================
+
+For Windows without PowerShell 3 or for installation without a command-line,
+download `ez_setup.py`_ using your preferred web browser or other technique
+and "run" that file.
+
+
+Unix (wget)
+===========
+
+Most Linux distributions come with wget.
+
+Download `ez_setup.py`_ and run it using the target Python version. The script
+will download the appropriate version and install it for you::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | python
+
+Note that you will may need to invoke the command with superuser privileges to
+install to the system Python::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
+
+Alternatively, Setuptools may be installed to a user-local path::
+
+    > wget https://bootstrap.pypa.io/ez_setup.py -O - | python - --user
+
+Unix including Mac OS X (curl)
+==============================
+
+If your system has curl installed, follow the ``wget`` instructions but
+replace ``wget`` with ``curl`` and ``-O`` with ``-o``. For example::
+
+    > curl https://bootstrap.pypa.io/ez_setup.py -o - | python
+
+
+Advanced Installation
+=====================
+
+For more advanced installation options, such as installing to custom
+locations or prefixes, download and extract the source
+tarball from `Setuptools on PyPI <https://pypi.python.org/pypi/setuptools>`_
+and run setup.py with any supported distutils and Setuptools options.
+For example::
+
+    setuptools-x.x$ python setup.py install --prefix=/opt/setuptools
+
+Use ``--help`` to get a full options list, but we recommend consulting
+the `EasyInstall manual`_ for detailed instructions, especially `the section
+on custom installation locations`_.
+
+.. _EasyInstall manual: https://pythonhosted.org/setuptools/EasyInstall
+.. _the section on custom installation locations: https://pythonhosted.org/setuptools/EasyInstall#custom-installation-locations
+
+
+Downloads
+=========
+
+All setuptools downloads can be found at `the project's home page in the Python
+Package Index`_.  Scroll to the very bottom of the page to find the links.
+
+.. _the project's home page in the Python Package Index: https://pypi.python.org/pypi/setuptools
+
+In addition to the PyPI downloads, the development version of ``setuptools``
+is available from the `Bitbucket repo`_, and in-development versions of the
+`0.6 branch`_ are available as well.
+
+.. _Bitbucket repo: https://bitbucket.org/pypa/setuptools/get/default.tar.gz#egg=setuptools-dev
+.. _0.6 branch: http://svn.python.org/projects/sandbox/branches/setuptools-0.6/#egg=setuptools-dev06
+
+Uninstalling
+============
+
+On Windows, if Setuptools was installed using an ``.exe`` or ``.msi``
+installer, simply use the uninstall feature of "Add/Remove Programs" in the
+Control Panel.
+
+Otherwise, to uninstall Setuptools or Distribute, regardless of the Python
+version, delete all ``setuptools*`` and ``distribute*`` files and
+directories from your system's ``site-packages`` directory
+(and any other ``sys.path`` directories) FIRST.
+
+If you are upgrading or otherwise plan to re-install Setuptools or Distribute,
+nothing further needs to be done. If you want to completely remove Setuptools,
+you may also want to remove the 'easy_install' and 'easy_install-x.x' scripts
+and associated executables installed to the Python scripts directory.
+

+* `The pkg_resources API reference`_
+* `Package Compatibility Notes`_ (user-maintained)
+* `The Internal Structure of Python Eggs`_
+
+Questions, comments, and bug reports should be directed to the `distutils-sig
+mailing list`_.  If you have written (or know of) any tutorials, documentation,
+plug-ins, or other resources for setuptools users, please let us know about
+them there, so this reference list can be updated.  If you have working,
+*tested* patches to correct problems or add features, you may submit them to
+the `setuptools bug tracker`_.

+
+* The original design for the ``.egg`` format and the ``pkg_resources`` API was
+  co-created by Phillip Eby and Bob Ippolito.  Bob also implemented the first
+  version of ``pkg_resources``, and supplied the OS X operating system version
+  compatibility algorithm.
+
+* Ian Bicking implemented many early "creature comfort" features of
+  easy_install, including support for downloading via Sourceforge and
+  Subversion repositories.  Ian's comments on the Web-SIG about WSGI
+  application deployment also inspired the concept of "entry points" in eggs,
+  and he has given talks at PyCon and elsewhere to inform and educate the
+  community about eggs and setuptools.
+
+* Jim Fulton contributed time and effort to build automated tests of various
+  aspects of ``easy_install``, and supplied the doctests for the command-line
+  ``.exe`` wrappers on Windows.
+
+* Phillip J. Eby is the seminal author of setuptools, and
+  first proposed the idea of an importable binary distribution format for
+  Python application plug-ins.
+
+* Significant parts of the implementation of setuptools were funded by the Open
+  Source Applications Foundation, to provide a plug-in infrastructure for the
+  Chandler PIM application.  In addition, many OSAF staffers (such as Mike
+  "Code Bear" Taylor) contributed their time and stress as guinea pigs for the
+  use of eggs and setuptools, even before eggs were "cool".  (Thanks, guys!)
+
+* Tarek Ziadé is the principal author of the Distribute fork, which
+  re-invigorated the community on the project, encouraged renewed innovation,
+  and addressed many defects.
+
+* Since the merge with Distribute, Jason R. Coombs is the
+  maintainer of setuptools.  The project is maintained in coordination with
+  the Python Packaging Authority (PyPA) and the larger Python community.

+=======
+CHANGES
+=======
+
+-----
+6.0.2
+-----
+
+* `Issue #262 <https://bitbucket.org/pypa/setuptools/issue/262>`_: Fixed regression in pip install due to egg-info directories
+  being omitted. Re-opens `Issue #118 <https://bitbucket.org/pypa/setuptools/issue/118>`_.
+
+-----
+6.0.1
+-----
+
+* `Issue #259 <https://bitbucket.org/pypa/setuptools/issue/259>`_: Fixed regression with namespace package handling on ``single
+  version, externally managed`` installs.
+
+---
+6.0
+---
+
+* `Issue #100 <https://bitbucket.org/pypa/setuptools/issue/100>`_: When building a distribution, Setuptools will no longer match
+  default files using platform-dependent case sensitivity, but rather will
+  only match the files if their case matches exactly. As a result, on Windows
+  and other case-insensitive file systems, files with names such as
+  'readme.txt' or 'README.TXT' will be omitted from the distribution and a
+  warning will be issued indicating that 'README.txt' was not found. Other
+  filenames affected are:
+
+    - README.rst
+    - README
+    - setup.cfg
+    - setup.py (or the script name)
+    - test/test*.py
+
+  Any users producing distributions with filenames that match those above
+  case-insensitively, but not case-sensitively, should rename those files in
+  their repository for better portability.
+* `Pull Request #72 <https://bitbucket.org/pypa/setuptools/pull-request/72>`_: When using ``single_version_externally_managed``, the
+  exclusion list now includes Python 3.2 ``__pycache__`` entries.
+* `Pull Request #76 <https://bitbucket.org/pypa/setuptools/pull-request/76>`_ and `Pull Request #78 <https://bitbucket.org/pypa/setuptools/pull-request/78>`_: lines in top_level.txt are now
+  ordered deterministically.
+* `Issue #118 <https://bitbucket.org/pypa/setuptools/issue/118>`_: The egg-info directory is now no longer included in the list
+  of outputs.
+* `Issue #258 <https://bitbucket.org/pypa/setuptools/issue/258>`_: Setuptools now patches distutils msvc9compiler to
+  recognize the specially-packaged compiler package for easy extension module
+  support on Python 2.6, 2.7, and 3.2.
+
+---
+5.8
+---
+
+* `Issue #237 <https://bitbucket.org/pypa/setuptools/issue/237>`_: ``pkg_resources`` now uses explicit detection of Python 2 vs.
+  Python 3, supporting environments where builtins have been patched to make
+  Python 3 look more like Python 2.
+
+---
+5.7
+---
+
+* `Issue #240 <https://bitbucket.org/pypa/setuptools/issue/240>`_: Based on real-world performance measures against 5.4, zip
+  manifests are now cached in all circumstances. The
+  ``PKG_RESOURCES_CACHE_ZIP_MANIFESTS`` environment variable is no longer
+  relevant. The observed "memory increase" referenced in the 5.4 release
+  notes and detailed in `Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154>`_ was likely not an increase over the status
+  quo, but rather only an increase over not storing the zip info at all.
+
+---
+5.6
+---
+
+* `Issue #242 <https://bitbucket.org/pypa/setuptools/issue/242>`_: Use absolute imports in svn_utils to avoid issues if the
+  installing package adds an xml module to the path.
+
+-----
+5.5.1
+-----
+
+* `Issue #239 <https://bitbucket.org/pypa/setuptools/issue/239>`_: Fix typo in 5.5 such that fix did not take.
+
+---
+5.5
+---
+
+* `Issue #239 <https://bitbucket.org/pypa/setuptools/issue/239>`_: Setuptools now includes the setup_requires directive on
+  Distribution objects and validates the syntax just like install_requires
+  and tests_require directives.
+
+-----
+5.4.2

+
+* `Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154>`_: ``pkg_resources`` will now cache the zip manifests rather than
+  re-processing the same file from disk multiple times, but only if the
+  environment variable ``PKG_RESOURCES_CACHE_ZIP_MANIFESTS`` is set. Clients
+  that package many modules in the same zip file will see some improvement
+  in startup time by enabling this feature. This feature is not enabled by

+
+* `Issue #125 <https://bitbucket.org/pypa/setuptools/issue/125>`_: Prevent Subversion support from creating a ~/.subversion
+  directory just for checking the presence of a Subversion repository.
+* `Issue #12 <https://bitbucket.org/pypa/setuptools/issue/12>`_: Namespace packages are now imported lazily.  That is, the mere
+  declaration of a namespace package in an egg on ``sys.path`` no longer
+  causes it to be imported when ``pkg_resources`` is imported.  Note that this
+  change means that all of a namespace package's ``__init__.py`` files must
+  include a ``declare_namespace()`` call in order to ensure that they will be
+  handled properly at runtime.  In 2.x it was possible to get away without
+  including the declaration, but only at the cost of forcing namespace
+  packages to be imported early, which 3.0 no longer does.
+* `Issue #148 <https://bitbucket.org/pypa/setuptools/issue/148>`_: When building (bdist_egg), setuptools no longer adds
+  ``__init__.py`` files to namespace packages. Any packages that rely on this
+  behavior will need to create ``__init__.py`` files and include the
+  ``declare_namespace()``.
+* `Issue #7 <https://bitbucket.org/pypa/setuptools/issue/7>`_: Setuptools itself is now distributed as a zip archive in addition to
+  tar archive. ez_setup.py now uses zip archive. This approach avoids the potential
+  security vulnerabilities presented by use of tar archives in ez_setup.py.
+  It also leverages the security features added to ZipFile.extract in Python 2.7.4.
+* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Removed deprecated Features functionality.
+* `Pull Request #28 <https://bitbucket.org/pypa/setuptools/pull-request/28>`_: Remove backport of ``_bytecode_filenames`` which is

+  setuptools for those versions of Python should use setuptools 1.x.
+* Removed ``setuptools.command.easy_install.HAS_USER_SITE``. Clients
+  expecting this boolean variable should use ``site.ENABLE_USER_SITE``
+  instead.
+* Removed ``pkg_resources.ImpWrapper``. Clients that expected this class
+  should use ``pkgutil.ImpImporter`` instead.

+1.4.2
+-----
+
+* `Issue #116 <https://bitbucket.org/pypa/setuptools/issue/116>`_: Correct TypeError when reading a local package index on Python
+  3.
+
+-----
+1.4.1
+-----
+
+* `Issue #114 <https://bitbucket.org/pypa/setuptools/issue/114>`_: Use ``sys.getfilesystemencoding`` for decoding config in
+  ``bdist_wininst`` distributions.
+
+* `Issue #105 <https://bitbucket.org/pypa/setuptools/issue/105>`_ and `Issue #113 <https://bitbucket.org/pypa/setuptools/issue/113>`_: Establish a more robust technique for
+  determining the terminal encoding::
+
+    1. Try ``getpreferredencoding``
+    2. If that returns US_ASCII or None, try the encoding from
+       ``getdefaultlocale``. If that encoding was a "fallback" because Python
+       could not figure it out from the environment or OS, encoding remains
+       unresolved.
+    3. If the encoding is resolved, then make sure Python actually implements
+       the encoding.
+    4. On the event of an error or unknown codec, revert to fallbacks
+       (UTF-8 on Darwin, ASCII on everything else).
+    5. On the encoding is 'mac-roman' on Darwin, use UTF-8 as 'mac-roman' was
+       a bug on older Python releases.
+
+    On a side note, it would seem that the encoding only matters for when SVN
+    does not yet support ``--xml`` and when getting repository and svn version
+    numbers. The ``--xml`` technique should yield UTF-8 according to some
+    messages on the SVN mailing lists. So if the version numbers are always
+    7-bit ASCII clean, it may be best to only support the file parsing methods
+    for legacy SVN releases and support for SVN without the subprocess command
+    would simple go away as support for the older SVNs does.

+1.4

+
+* `Issue #27 <https://bitbucket.org/pypa/setuptools/issue/27>`_: ``easy_install`` will now use credentials from .pypirc if

+1.3
+---
+
+* Address security vulnerability in SSL match_hostname check as reported in

+* Correct NameError in ``ssl_support`` module (``socket.error``).
+
+---
+1.2
+---
+
+* `Issue #26 <https://bitbucket.org/pypa/setuptools/issue/26>`_: Add support for SVN 1.7. Special thanks to Philip Thiem for the
+  contribution.
+* `Issue #93 <https://bitbucket.org/pypa/setuptools/issue/93>`_: Wheels are now distributed with every release. Note that as
+  reported in `Issue #108 <https://bitbucket.org/pypa/setuptools/issue/108>`_, as of Pip 1.4, scripts aren't installed properly
+  from wheels. Therefore, if using Pip to install setuptools from a wheel,
+  the ``easy_install`` command will not be available.
+* Setuptools "natural" launcher support, introduced in 1.0, is now officially
+  supported.
+
+-----
+1.1.7
+-----
+
+* Fixed behavior of NameError handling in 'script template (dev).py' (script
+  launcher for 'develop' installs).
+* ``ez_setup.py`` now ensures partial downloads are cleaned up following
+  a failed download.
+* `Distribute #363 <https://bitbucket.org/tarek/distribute/issue/363>`_ and `Issue #55 <https://bitbucket.org/pypa/setuptools/issue/55>`_: Skip an sdist test that fails on locales
+  other than UTF-8.
+
+-----
+1.1.6
+-----
+
+* `Distribute #349 <https://bitbucket.org/tarek/distribute/issue/349>`_: ``sandbox.execfile`` now opens the target file in binary

+
+-----
+1.1.5
+-----
+
+* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Second attempt at fix (logic was reversed).
+

+1.1.4
+-----
+
+* `Issue #77 <https://bitbucket.org/pypa/setuptools/issue/77>`_: Fix error in upload command (Python 2.4).
+
+-----
+1.1.3
+-----
+
+* Fix NameError in previous patch.
+
+-----
+1.1.2
+-----
+
+* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Correct issue where 404 errors are returned for URLs with
+  fragments in them (such as #egg=).
+
+-----
+1.1.1
+-----
+
+* `Issue #75 <https://bitbucket.org/pypa/setuptools/issue/75>`_: Add ``--insecure`` option to ez_setup.py to accommodate
+  environments where a trusted SSL connection cannot be validated.
+* `Issue #76 <https://bitbucket.org/pypa/setuptools/issue/76>`_: Fix AttributeError in upload command with Python 2.4.
+
+---
+1.1
+---
+
+* `Issue #71 <https://bitbucket.org/pypa/setuptools/issue/71>`_ (`Distribute #333 <https://bitbucket.org/tarek/distribute/issue/333>`_): EasyInstall now puts less emphasis on the
+  condition when a host is blocked via ``--allow-hosts``.
+* `Issue #72 <https://bitbucket.org/pypa/setuptools/issue/72>`_: Restored Python 2.4 compatibility in ``ez_setup.py``.
+
+---
+1.0
+---
+
+* `Issue #60 <https://bitbucket.org/pypa/setuptools/issue/60>`_: On Windows, Setuptools supports deferring to another launcher,
+  such as Vinay Sajip's `pylauncher <https://bitbucket.org/pypa/pylauncher>`_
+  (included with Python 3.3) to launch console and GUI scripts and not install
+  its own launcher executables. This experimental functionality is currently
+  only enabled if  the ``SETUPTOOLS_LAUNCHER`` environment variable is set to
+  "natural". In the future, this behavior may become default, but only after
+  it has matured and seen substantial adoption. The ``SETUPTOOLS_LAUNCHER``
+  also accepts "executable" to force the default behavior of creating launcher
+  executables.
+* `Issue #63 <https://bitbucket.org/pypa/setuptools/issue/63>`_: Bootstrap script (ez_setup.py) now prefers Powershell, curl, or
+  wget for retrieving the Setuptools tarball for improved security of the
+  install. The script will still fall back to a simple ``urlopen`` on
+  platforms that do not have these tools.
+* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Deprecated the ``Features`` functionality.
+* `Issue #52 <https://bitbucket.org/pypa/setuptools/issue/52>`_: In ``VerifyingHTTPSConn``, handle a tunnelled (proxied)
+  connection.
+
+Backward-Incompatible Changes
+=============================
+
+This release includes a couple of backward-incompatible changes, but most if
+not all users will find 1.0 a drop-in replacement for 0.9.
+
+* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: Normalized API of environment marker support. Specifically,
+  removed line number and filename from SyntaxErrors when returned from
+  `pkg_resources.invalid_marker`. Any clients depending on the specific
+  string representation of exceptions returned by that function may need to
+  be updated to account for this change.
+* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: SyntaxErrors generated by `pkg_resources.invalid_marker` are
+  normalized for cross-implementation consistency.
+* Removed ``--ignore-conflicts-at-my-risk`` and ``--delete-conflicting``
+  options to easy_install. These options have been deprecated since 0.6a11.
+
+-----
+0.9.8
+-----

+* `Issue #34 <https://bitbucket.org/pypa/setuptools/issue/34>`_: Documentation now refers to bootstrap script in code repository
+  referenced by bookmark.
+* Add underscore-separated keys to environment markers (markerlib).
+
+-----
+0.9.6
+-----
+
+* `Issue #44 <https://bitbucket.org/pypa/setuptools/issue/44>`_: Test failure on Python 2.4 when MD5 hash doesn't have a `.name`

+-----
+
+* `Issue #42 <https://bitbucket.org/pypa/setuptools/issue/42>`_: Fix regression where blank checksums would trigger an
+  ``AttributeError``.
+
+-----
+0.9.1
+-----
+
+* `Distribute #386 <https://bitbucket.org/tarek/distribute/issue/386>`_: Allow other positional and keyword arguments to os.open.
+* Corrected dependency on certifi mis-referenced in 0.9.
+
+---
+0.9
+---
+
+* `package_index` now validates hashes other than MD5 in download links.
+
+---
+0.8
+---
+
+* Code base now runs on Python 2.4 - Python 3.3 without Python 2to3
+  conversion.
+
+-----
+0.7.8
+-----
+
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Yet another fix for yet another regression.
+
+-----
+0.7.7
+-----
+
+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Repair AttributeError created in last release (redo).

+
+-----
+0.7.6

+* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Merged additional warning from Distribute 0.6.46.
+* Now honor the environment variable
+  ``SETUPTOOLS_DISABLE_VERSIONED_EASY_INSTALL_SCRIPT`` in addition to the now
+  deprecated ``DISTRIBUTE_DISABLE_VERSIONED_EASY_INSTALL_SCRIPT``.
+
+-----
+0.7.4
+-----
+
+* `Issue #20 <https://bitbucket.org/pypa/setuptools/issue/20>`_: Fix comparison of parsed SVN version on Python 3.
+
+-----
+0.7.3
+-----
+
+* `Issue #1 <https://bitbucket.org/pypa/setuptools/issue/1>`_: Disable installation of Windows-specific files on non-Windows systems.
+* Use new sysconfig module with Python 2.7 or >=3.2.
+
+-----
+0.7.2
+-----
+
+* `Issue #14 <https://bitbucket.org/pypa/setuptools/issue/14>`_: Use markerlib when the `parser` module is not available.
+* `Issue #10 <https://bitbucket.org/pypa/setuptools/issue/10>`_: ``ez_setup.py`` now uses HTTPS to download setuptools from PyPI.
+
+-----
+0.7.1
+-----
+
+* Fix NameError (`Issue #3 <https://bitbucket.org/pypa/setuptools/issue/3>`_) again - broken in bad merge.
+
+---
+0.7
+---
+
+* Merged Setuptools and Distribute. See docs/merge.txt for details.
+
+Added several features that were slated for setuptools 0.6c12:
+
+* Index URL now defaults to HTTPS.
+* Added experimental environment marker support. Now clients may designate a
+  PEP-426 environment marker for "extra" dependencies. Setuptools uses this
+  feature in ``setup.py`` for optional SSL and certificate validation support
+  on older platforms. Based on Distutils-SIG discussions, the syntax is
+  somewhat tentative. There should probably be a PEP with a firmer spec before
+  the feature should be considered suitable for use.
+* Added support for SSL certificate validation when installing packages from
+  an HTTPS service.
+
+-----
+0.7b4
+-----
+
+* `Issue #3 <https://bitbucket.org/pypa/setuptools/issue/3>`_: Fixed NameError in SSL support.
+
+------
+0.6.49
+------

+  accompanied by a manifest on 32-bit Windows environments to avoid the

+  <http://technet.microsoft.com/en-us/library/cc709628%28WS.10%29.aspx>`_.

+  under Windows. Easy_install now skips all directories when processing
+  metadata scripts.
+
+------
+0.6.35
+------
+
+
+Note this release is backward-incompatible with distribute 0.6.23-0.6.34 in

+* `Distribute #334 <https://bitbucket.org/tarek/distribute/issue/334>`_: Provide workaround for packages that reference `sys.__stdout__`
+  such as numpy does. This change should address
+  `virtualenv `#359 <https://bitbucket.org/pypa/setuptools/issue/359>`_ <https://github.com/pypa/virtualenv/issues/359>`_ as long
+  as the system encoding is UTF-8 or the IO encoding is specified in the
+  environment, i.e.::
+
+     PYTHONIOENCODING=utf8 pip install numpy
+
+* Fix for encoding issue when installing from Windows executable on Python 3.
+* `Distribute #323 <https://bitbucket.org/tarek/distribute/issue/323>`_: Allow `setup_requires` requirements to supercede installed
+  requirements. Added some new keyword arguments to existing pkg_resources
+  methods. Also had to updated how __path__ is handled for namespace packages
+  to ensure that when a new egg distribution containing a namespace package is
+  placed on sys.path, the entries in __path__ are found in the same order they
+  would have been in had that egg been on the path when pkg_resources was
+  first imported.

+  as the egg link would go to the Python 2 source. Linking to the 2to3'd code
+  in build/lib makes it work, although you will have to rebuild the module
+  before testing it.
+* `Distribute #306 <https://bitbucket.org/tarek/distribute/issue/306>`_: Even if 2to3 is used, we build in-place under Python 2.

+0.6c9
+-----
+
+ * Fixed a missing files problem when using Windows source distributions on
+   non-Windows platforms, due to distutils not handling manifest file line
+   endings correctly.
+
+ * Updated Pyrex support to work with Pyrex 0.9.6 and higher.
+
+ * Minor changes for Jython compatibility, including skipping tests that can't
+   work on Jython.
+
+ * Fixed not installing eggs in ``install_requires`` if they were also used for
+   ``setup_requires`` or ``tests_require``.
+
+ * Fixed not fetching eggs in ``install_requires`` when running tests.
+
+ * Allow ``ez_setup.use_setuptools()`` to upgrade existing setuptools
+   installations when called from a standalone ``setup.py``.
+
+ * Added a warning if a namespace package is declared, but its parent package
+   is not also declared as a namespace.
+
+ * Support Subversion 1.5
+
+ * Removed use of deprecated ``md5`` module if ``hashlib`` is available
+
+ * Fixed ``bdist_wininst upload`` trying to upload the ``.exe`` twice
+
+ * Fixed ``bdist_egg`` putting a ``native_libs.txt`` in the source package's
+   ``.egg-info``, when it should only be in the built egg's ``EGG-INFO``.
+
+ * Ensure that _full_name is set on all shared libs before extensions are
+   checked for shared lib usage.  (Fixes a bug in the experimental shared
+   library build support.)
+
+ * Fix to allow unpacked eggs containing native libraries to fail more
+   gracefully under Google App Engine (with an ``ImportError`` loading the
+   C-based module, instead of getting a ``NameError``).
+
+-----
+0.6c7
+-----
+
+ * Fixed ``distutils.filelist.findall()`` crashing on broken symlinks, and
+   ``egg_info`` command failing on new, uncommitted SVN directories.
+
+ * Fix import problems with nested namespace packages installed via
+   ``--root`` or ``--single-version-externally-managed``, due to the
+   parent package not having the child package as an attribute.
+
+-----
+0.6c6
+-----
+
+ * Added ``--egg-path`` option to ``develop`` command, allowing you to force
+   ``.egg-link`` files to use relative paths (allowing them to be shared across
+   platforms on a networked drive).
+
+ * Fix not building binary RPMs correctly.
+
+ * Fix "eggsecutables" (such as setuptools' own egg) only being runnable with
+   bash-compatible shells.
+
+ * Fix ``#!`` parsing problems in Windows ``.exe`` script wrappers, when there
+   was whitespace inside a quoted argument or at the end of the ``#!`` line
+   (a regression introduced in 0.6c4).
+
+ * Fix ``test`` command possibly failing if an older version of the project
+   being tested was installed on ``sys.path`` ahead of the test source
+   directory.
+
+ * Fix ``find_packages()`` treating ``ez_setup`` and directories with ``.`` in
+   their names as packages.
+
+-----
+0.6c5
+-----
+
+ * Fix uploaded ``bdist_rpm`` packages being described as ``bdist_egg``
+   packages under Python versions less than 2.5.
+
+ * Fix uploaded ``bdist_wininst`` packages being described as suitable for
+   "any" version by Python 2.5, even if a ``--target-version`` was specified.
+
+-----
+0.6c4
+-----
+
+ * Overhauled Windows script wrapping to support ``bdist_wininst`` better.
+   Scripts installed with ``bdist_wininst`` will always use ``#!python.exe`` or
+   ``#!pythonw.exe`` as the executable name (even when built on non-Windows
+   platforms!), and the wrappers will look for the executable in the script's
+   parent directory (which should find the right version of Python).
+
+ * Fix ``upload`` command not uploading files built by ``bdist_rpm`` or
+   ``bdist_wininst`` under Python 2.3 and 2.4.
+
+ * Add support for "eggsecutable" headers: a ``#!/bin/sh`` script that is
+   prepended to an ``.egg`` file to allow it to be run as a script on Unix-ish
+   platforms.  (This is mainly so that setuptools itself can have a single-file
+   installer on Unix, without doing multiple downloads, dealing with firewalls,
+   etc.)
+
+ * Fix problem with empty revision numbers in Subversion 1.4 ``entries`` files
+
+ * Use cross-platform relative paths in ``easy-install.pth`` when doing
+   ``develop`` and the source directory is a subdirectory of the installation
+   target directory.
+
+ * Fix a problem installing eggs with a system packaging tool if the project
+   contained an implicit namespace package; for example if the ``setup()``
+   listed a namespace package ``foo.bar`` without explicitly listing ``foo``
+   as a namespace package.
+
+-----
+0.6c3
+-----
+
+ * Fixed breakages caused by Subversion 1.4's new "working copy" format
+
+-----
+0.6c2
+-----
+
+ * The ``ez_setup`` module displays the conflicting version of setuptools (and
+   its installation location) when a script requests a version that's not
+   available.
+
+ * Running ``setup.py develop`` on a setuptools-using project will now install
+   setuptools if needed, instead of only downloading the egg.
+
+-----
+0.6c1
+-----
+
+ * Fixed ``AttributeError`` when trying to download a ``setup_requires``
+   dependency when a distribution lacks a ``dependency_links`` setting.
+
+ * Made ``zip-safe`` and ``not-zip-safe`` flag files contain a single byte, so
+   as to play better with packaging tools that complain about zero-length
+   files.
+
+ * Made ``setup.py develop`` respect the ``--no-deps`` option, which it
+   previously was ignoring.
+
+ * Support ``extra_path`` option to ``setup()`` when ``install`` is run in
+   backward-compatibility mode.
+
+ * Source distributions now always include a ``setup.cfg`` file that explicitly
+   sets ``egg_info`` options such that they produce an identical version number
+   to the source distribution's version number.  (Previously, the default
+   version number could be different due to the use of ``--tag-date``, or if
+   the version was overridden on the command line that built the source
+   distribution.)
+
+-----
+0.6b4
+-----
+
+ * Fix ``register`` not obeying name/version set by ``egg_info`` command, if
+   ``egg_info`` wasn't explicitly run first on the same command line.
+
+ * Added ``--no-date`` and ``--no-svn-revision`` options to ``egg_info``
+   command, to allow suppressing tags configured in ``setup.cfg``.
+
+ * Fixed redundant warnings about missing ``README`` file(s); it should now
+   appear only if you are actually a source distribution.
+
+-----
+0.6b3
+-----
+
+ * Fix ``bdist_egg`` not including files in subdirectories of ``.egg-info``.
+
+ * Allow ``.py`` files found by the ``include_package_data`` option to be
+   automatically included.  Remove duplicate data file matches if both
+   ``include_package_data`` and ``package_data`` are used to refer to the same
+   files.
+
+-----
+0.6b1
+-----
+
+ * Strip ``module`` from the end of compiled extension modules when computing
+   the name of a ``.py`` loader/wrapper.  (Python's import machinery ignores
+   this suffix when searching for an extension module.)
+
+------
+0.6a11
+------
+
+ * Added ``test_loader`` keyword to support custom test loaders
+
+ * Added ``setuptools.file_finders`` entry point group to allow implementing
+   revision control plugins.
+
+ * Added ``--identity`` option to ``upload`` command.
+
+ * Added ``dependency_links`` to allow specifying URLs for ``--find-links``.
+
+ * Enhanced test loader to scan packages as well as modules, and call
+   ``additional_tests()`` if present to get non-unittest tests.
+
+ * Support namespace packages in conjunction with system packagers, by omitting
+   the installation of any ``__init__.py`` files for namespace packages, and
+   adding a special ``.pth`` file to create a working package in
+   ``sys.modules``.
+
+ * Made ``--single-version-externally-managed`` automatic when ``--root`` is
+   used, so that most system packagers won't require special support for
+   setuptools.
+
+ * Fixed ``setup_requires``, ``tests_require``, etc. not using ``setup.cfg`` or
+   other configuration files for their option defaults when installing, and
+   also made the install use ``--multi-version`` mode so that the project
+   directory doesn't need to support .pth files.
+
+ * ``MANIFEST.in`` is now forcibly closed when any errors occur while reading
+   it.  Previously, the file could be left open and the actual error would be
+   masked by problems trying to remove the open file on Windows systems.
+
+------
+0.6a10
+------
+
+ * Fixed the ``develop`` command ignoring ``--find-links``.
+
+-----
+0.6a9
+-----
+
+ * The ``sdist`` command no longer uses the traditional ``MANIFEST`` file to
+   create source distributions.  ``MANIFEST.in`` is still read and processed,
+   as are the standard defaults and pruning.  But the manifest is built inside
+   the project's ``.egg-info`` directory as ``SOURCES.txt``, and it is rebuilt
+   every time the ``egg_info`` command is run.
+
+ * Added the ``include_package_data`` keyword to ``setup()``, allowing you to
+   automatically include any package data listed in revision control or
+   ``MANIFEST.in``
+
+ * Added the ``exclude_package_data`` keyword to ``setup()``, allowing you to
+   trim back files included via the ``package_data`` and
+   ``include_package_data`` options.
+
+ * Fixed ``--tag-svn-revision`` not working when run from a source
+   distribution.
+
+ * Added warning for namespace packages with missing ``declare_namespace()``
+
+ * Added ``tests_require`` keyword to ``setup()``, so that e.g. packages
+   requiring ``nose`` to run unit tests can make this dependency optional
+   unless the ``test`` command is run.
+
+ * Made all commands that use ``easy_install`` respect its configuration
+   options, as this was causing some problems with ``setup.py install``.
+
+ * Added an ``unpack_directory()`` driver to ``setuptools.archive_util``, so
+   that you can process a directory tree through a processing filter as if it
+   were a zipfile or tarfile.
+
+ * Added an internal ``install_egg_info`` command to use as part of old-style
+   ``install`` operations, that installs an ``.egg-info`` directory with the
+   package.
+
+ * Added a ``--single-version-externally-managed`` option to the ``install``
+   command so that you can more easily wrap a "flat" egg in a system package.
+
+ * Enhanced ``bdist_rpm`` so that it installs single-version eggs that
+   don't rely on a ``.pth`` file.  The ``--no-egg`` option has been removed,
+   since all RPMs are now built in a more backwards-compatible format.
+
+ * Support full roundtrip translation of eggs to and from ``bdist_wininst``
+   format.  Running ``bdist_wininst`` on a setuptools-based package wraps the
+   egg in an .exe that will safely install it as an egg (i.e., with metadata
+   and entry-point wrapper scripts), and ``easy_install`` can turn the .exe
+   back into an ``.egg`` file or directory and install it as such.
+
+
+-----
+0.6a8
+-----
+
+ * Fixed some problems building extensions when Pyrex was installed, especially
+   with Python 2.4 and/or packages using SWIG.
+
+ * Made ``develop`` command accept all the same options as ``easy_install``,
+   and use the ``easy_install`` command's configuration settings as defaults.
+
+ * Made ``egg_info --tag-svn-revision`` fall back to extracting the revision
+   number from ``PKG-INFO`` in case it is being run on a source distribution of
+   a snapshot taken from a Subversion-based project.
+
+ * Automatically detect ``.dll``, ``.so`` and ``.dylib`` files that are being
+   installed as data, adding them to ``native_libs.txt`` automatically.
+
+ * Fixed some problems with fresh checkouts of projects that don't include
+   ``.egg-info/PKG-INFO`` under revision control and put the project's source
+   code directly in the project directory.  If such a package had any
+   requirements that get processed before the ``egg_info`` command can be run,
+   the setup scripts would fail with a "Missing 'Version:' header and/or
+   PKG-INFO file" error, because the egg runtime interpreted the unbuilt
+   metadata in a directory on ``sys.path`` (i.e. the current directory) as
+   being a corrupted egg.  Setuptools now monkeypatches the distribution
+   metadata cache to pretend that the egg has valid version information, until
+   it has a chance to make it actually be so (via the ``egg_info`` command).
+
+-----
+0.6a5
+-----
+
+ * Fixed missing gui/cli .exe files in distribution.  Fixed bugs in tests.
+
+-----
+0.6a3
+-----
+
+ * Added ``gui_scripts`` entry point group to allow installing GUI scripts
+   on Windows and other platforms.  (The special handling is only for Windows;
+   other platforms are treated the same as for ``console_scripts``.)
+
+-----
+0.6a2
+-----
+
+ * Added ``console_scripts`` entry point group to allow installing scripts
+   without the need to create separate script files.  On Windows, console
+   scripts get an ``.exe`` wrapper so you can just type their name.  On other
+   platforms, the scripts are written without a file extension.
+
+-----
+0.6a1
+-----
+
+ * Added support for building "old-style" RPMs that don't install an egg for
+   the target package, using a ``--no-egg`` option.
+
+ * The ``build_ext`` command now works better when using the ``--inplace``
+   option and multiple Python versions.  It now makes sure that all extensions
+   match the current Python version, even if newer copies were built for a
+   different Python version.
+
+ * The ``upload`` command no longer attaches an extra ``.zip`` when uploading
+   eggs, as PyPI now supports egg uploads without trickery.
+
+ * The ``ez_setup`` script/module now displays a warning before downloading
+   the setuptools egg, and attempts to check the downloaded egg against an
+   internal MD5 checksum table.
+
+ * Fixed the ``--tag-svn-revision`` option of ``egg_info`` not finding the
+   latest revision number; it was using the revision number of the directory
+   containing ``setup.py``, not the highest revision number in the project.
+
+ * Added ``eager_resources`` setup argument
+
+ * The ``sdist`` command now recognizes Subversion "deleted file" entries and
+   does not include them in source distributions.
+
+ * ``setuptools`` now embeds itself more thoroughly into the distutils, so that
+   other distutils extensions (e.g. py2exe, py2app) will subclass setuptools'
+   versions of things, rather than the native distutils ones.
+
+ * Added ``entry_points`` and ``setup_requires`` arguments to ``setup()``;
+   ``setup_requires`` allows you to automatically find and download packages
+   that are needed in order to *build* your project (as opposed to running it).
+
+ * ``setuptools`` now finds its commands, ``setup()`` argument validators, and
+   metadata writers using entry points, so that they can be extended by
+   third-party packages.  See `Creating distutils Extensions
+   <http://pythonhosted.org/setuptools/setuptools.html#creating-distutils-extensions>`_
+   for more details.
+
+ * The vestigial ``depends`` command has been removed.  It was never finished
+   or documented, and never would have worked without EasyInstall - which it
+   pre-dated and was never compatible with.
+
+------
+0.5a12
+------
+
+ * The zip-safety scanner now checks for modules that might be used with
+   ``python -m``, and marks them as unsafe for zipping, since Python 2.4 can't
+   handle ``-m`` on zipped modules.
+
+------
+0.5a11
+------
+
+ * Fix breakage of the "develop" command that was caused by the addition of
+   ``--always-unzip`` to the ``easy_install`` command.
+
+-----
+0.5a9
+-----
+
+ * Include ``svn:externals`` directories in source distributions as well as
+   normal subversion-controlled files and directories.
+
+ * Added ``exclude=patternlist`` option to ``setuptools.find_packages()``
+
+ * Changed --tag-svn-revision to include an "r" in front of the revision number
+   for better readability.
+
+ * Added ability to build eggs without including source files (except for any
+   scripts, of course), using the ``--exclude-source-files`` option to
+   ``bdist_egg``.
+
+ * ``setup.py install`` now automatically detects when an "unmanaged" package
+   or module is going to be on ``sys.path`` ahead of a package being installed,
+   thereby preventing the newer version from being imported.  If this occurs,
+   a warning message is output to ``sys.stderr``, but installation proceeds
+   anyway.  The warning message informs the user what files or directories
+   need deleting, and advises them they can also use EasyInstall (with the
+   ``--delete-conflicting`` option) to do it automatically.
+
+ * The ``egg_info`` command now adds a ``top_level.txt`` file to the metadata
+   directory that lists all top-level modules and packages in the distribution.
+   This is used by the ``easy_install`` command to find possibly-conflicting
+   "unmanaged" packages when installing the distribution.
+
+ * Added ``zip_safe`` and ``namespace_packages`` arguments to ``setup()``.
+   Added package analysis to determine zip-safety if the ``zip_safe`` flag
+   is not given, and advise the author regarding what code might need changing.
+
+ * Fixed the swapped ``-d`` and ``-b`` options of ``bdist_egg``.
+
+-----
+0.5a8
+-----
+
+ * The "egg_info" command now always sets the distribution metadata to "safe"
+   forms of the distribution name and version, so that distribution files will
+   be generated with parseable names (i.e., ones that don't include '-' in the
+   name or version).  Also, this means that if you use the various ``--tag``
+   options of "egg_info", any distributions generated will use the tags in the
+   version, not just egg distributions.
+
+ * Added support for defining command aliases in distutils configuration files,
+   under the "[aliases]" section.  To prevent recursion and to allow aliases to
+   call the command of the same name, a given alias can be expanded only once
+   per command-line invocation.  You can define new aliases with the "alias"
+   command, either for the local, global, or per-user configuration.
+
+ * Added "rotate" command to delete old distribution files, given a set of
+   patterns to match and the number of files to keep.  (Keeps the most
+   recently-modified distribution files matching each pattern.)
+
+ * Added "saveopts" command that saves all command-line options for the current
+   invocation to the local, global, or per-user configuration file.  Useful for
+   setting defaults without having to hand-edit a configuration file.
+
+ * Added a "setopt" command that sets a single option in a specified distutils
+   configuration file.
+
+-----
+0.5a7
+-----
+
+ * Added "upload" support for egg and source distributions, including a bug
+   fix for "upload" and a temporary workaround for lack of .egg support in
+   PyPI.
+
+-----
+0.5a6
+-----
+
+ * Beefed up the "sdist" command so that if you don't have a MANIFEST.in, it
+   will include all files under revision control (CVS or Subversion) in the
+   current directory, and it will regenerate the list every time you create a
+   source distribution, not just when you tell it to.  This should make the
+   default "do what you mean" more often than the distutils' default behavior
+   did, while still retaining the old behavior in the presence of MANIFEST.in.
+
+ * Fixed the "develop" command always updating .pth files, even if you
+   specified ``-n`` or ``--dry-run``.
+
+ * Slightly changed the format of the generated version when you use
+   ``--tag-build`` on the "egg_info" command, so that you can make tagged
+   revisions compare *lower* than the version specified in setup.py (e.g. by
+   using ``--tag-build=dev``).
+
+-----
+0.5a5
+-----
+
+ * Added ``develop`` command to ``setuptools``-based packages.  This command
+   installs an ``.egg-link`` pointing to the package's source directory, and
+   script wrappers that ``execfile()`` the source versions of the package's
+   scripts.  This lets you put your development checkout(s) on sys.path without
+   having to actually install them.  (To uninstall the link, use
+   use ``setup.py develop --uninstall``.)
+
+ * Added ``egg_info`` command to ``setuptools``-based packages.  This command
+   just creates or updates the "projectname.egg-info" directory, without
+   building an egg.  (It's used by the ``bdist_egg``, ``test``, and ``develop``
+   commands.)
+
+ * Enhanced the ``test`` command so that it doesn't install the package, but
+   instead builds any C extensions in-place, updates the ``.egg-info``
+   metadata, adds the source directory to ``sys.path``, and runs the tests
+   directly on the source.  This avoids an "unmanaged" installation of the
+   package to ``site-packages`` or elsewhere.
+
+ * Made ``easy_install`` a standard ``setuptools`` command, moving it from
+   the ``easy_install`` module to ``setuptools.command.easy_install``.  Note
+   that if you were importing or extending it, you must now change your imports
+   accordingly.  ``easy_install.py`` is still installed as a script, but not as
+   a module.
+
+-----
+0.5a4
+-----
+
+ * Setup scripts using setuptools can now list their dependencies directly in
+   the setup.py file, without having to manually create a ``depends.txt`` file.
+   The ``install_requires`` and ``extras_require`` arguments to ``setup()``
+   are used to create a dependencies file automatically.  If you are manually
+   creating ``depends.txt`` right now, please switch to using these setup
+   arguments as soon as practical, because ``depends.txt`` support will be
+   removed in the 0.6 release cycle.  For documentation on the new arguments,
+   see the ``setuptools.dist.Distribution`` class.
+
+ * Setup scripts using setuptools now always install using ``easy_install``
+   internally, for ease of uninstallation and upgrading.
+
+-----
+0.5a1
+-----
+
+ * Added support for "self-installation" bootstrapping.  Packages can now
+   include ``ez_setup.py`` in their source distribution, and add the following
+   to their ``setup.py``, in order to automatically bootstrap installation of
+   setuptools as part of their setup process::
+
+    from ez_setup import use_setuptools
+    use_setuptools()
+
+    from setuptools import setup
+    # etc...
+
+-----
+0.4a2
+-----
+
+ * Added ``ez_setup.py`` installer/bootstrap script to make initial setuptools
+   installation easier, and to allow distributions using setuptools to avoid
+   having to include setuptools in their source distribution.
+
+ * All downloads are now managed by the ``PackageIndex`` class (which is now
+   subclassable and replaceable), so that embedders can more easily override
+   download logic, give download progress reports, etc.  The class has also
+   been moved to the new ``setuptools.package_index`` module.
+
+ * The ``Installer`` class no longer handles downloading, manages a temporary
+   directory, or tracks the ``zip_ok`` option.  Downloading is now handled
+   by ``PackageIndex``, and ``Installer`` has become an ``easy_install``
+   command class based on ``setuptools.Command``.
+
+ * There is a new ``setuptools.sandbox.run_setup()`` API to invoke a setup
+   script in a directory sandbox, and a new ``setuptools.archive_util`` module
+   with an ``unpack_archive()`` API.  These were split out of EasyInstall to
+   allow reuse by other tools and applications.
+
+ * ``setuptools.Command`` now supports reinitializing commands using keyword
+   arguments to set/reset options.  Also, ``Command`` subclasses can now set
+   their ``command_consumes_arguments`` attribute to ``True`` in order to
+   receive an ``args`` option containing the rest of the command line.
+
+-----
+0.3a2
+-----
+
+ * Added new options to ``bdist_egg`` to allow tagging the egg's version number
+   with a subversion revision number, the current date, or an explicit tag
+   value.  Run ``setup.py bdist_egg --help`` to get more information.
+
+ * Misc. bug fixes
+
+-----
+0.3a1
+-----
+
+ * Initial release.

+
+    zipimport.zipimporter objects are Python loaders charged with importing
+    data packaged inside zip archives. If stale loaders referencing the
+    original distribution, are left behind, they can fail to load modules from
+    the replacement distribution. E.g. if an old zipimport.zipimporter instance
+    is used to load data from a new zipped egg archive, it may cause the

+    archive directory information. This, of course, assumes that the

+class Distribution(_Distribution):
+    """Distribution with support for features, tests, and package data
+
+    This is an enhanced version of 'distutils.dist.Distribution' that
+    effectively adds the following new optional keyword arguments to 'setup()':
+
+     'install_requires' -- a string or sequence of strings specifying project
+        versions that the distribution requires when installed, in the format
+        used by 'pkg_resources.require()'.  They will be installed
+        automatically when the package is installed.  If you wish to use
+        packages that are not available in PyPI, or want to give your users an
+        alternate download location, you can add a 'find_links' option to the
+        '[easy_install]' section of your project's 'setup.cfg' file, and then
+        setuptools will scan the listed web pages for links that satisfy the
+        requirements.
+
+     'extras_require' -- a dictionary mapping names of optional "extras" to the
+        additional requirement(s) that using those extras incurs. For example,
+        this::
+
+            extras_require = dict(reST = ["docutils>=0.3", "reSTedit"])
+
+        indicates that the distribution can optionally provide an extra
+        capability called "reST", but it can only be used if docutils and
+        reSTedit are installed.  If the user installs your package using
+        EasyInstall and requests one of your extras, the corresponding
+        additional requirements will be installed if needed.
+
+     'features' **deprecated** -- a dictionary mapping option names to
+        'setuptools.Feature'
+        objects.  Features are a portion of the distribution that can be
+        included or excluded based on user options, inter-feature dependencies,
+        and availability on the current system.  Excluded features are omitted
+        from all setup commands, including source and binary distributions, so
+        you can create multiple distributions from the same source tree.
+        Feature names should be valid Python identifiers, except that they may
+        contain the '-' (minus) sign.  Features can be included or excluded
+        via the command line options '--with-X' and '--without-X', where 'X' is
+        the name of the feature.  Whether a feature is included by default, and
+        whether you are allowed to control this from the command line, is
+        determined by the Feature object.  See the 'Feature' class for more
+        information.
+
+     'test_suite' -- the name of a test suite to run for the 'test' command.
+        If the user runs 'python setup.py test', the package will be installed,
+        and the named test suite will be run.  The format is the same as
+        would be used on a 'unittest.py' command line.  That is, it is the
+        dotted name of an object to import and call to generate a test suite.
+
+     'package_data' -- a dictionary mapping package names to lists of filenames
+        or globs to use to find data files contained in the named packages.
+        If the dictionary has filenames or globs listed under '""' (the empty
+        string), those names will be searched for in every package, in addition
+        to any names for the specific package.  Data files found using these
+        names/globs will be installed along with the package, in the same
+        location as the package.  Note that globs are allowed to reference
+        the contents of non-package subdirectories, as long as you use '/' as
+        a path separator.  (Globs are automatically converted to
+        platform-specific paths at runtime.)
+
+    In addition to these new keywords, this class also has several new methods
+    for manipulating the distribution's contents.  For example, the 'include()'
+    and 'exclude()' methods can be thought of as in-place add and subtract
+    commands that add or remove packages, modules, extensions, and so on from
+    the distribution.  They are used by the feature subsystem to configure the
+    distribution for the included and excluded features.

+

+
+      'description' -- a short, human readable description of the feature, to
+         be used in error messages, and option help messages.
+
+      'standard' -- if true, the feature is included by default if it is
+         available on the current system.  Otherwise, the feature is only
+         included if requested via a command line '--with-X' option, or if
+         another included feature requires it.  The default setting is 'False'.
+
+      'available' -- if true, the feature is available for installation on the
+         current system.  The default setting is 'True'.
+
+      'optional' -- if true, the feature's inclusion can be controlled from the
+         command line, using the '--with-X' or '--without-X' options.  If
+         false, the feature's inclusion status is determined automatically,
+         based on 'availabile', 'standard', and whether any other feature
+         requires it.  The default setting is 'True'.
+
+      'require_features' -- a string or sequence of strings naming features
+         that should also be included if this feature is included.  Defaults to
+         empty list.  May also contain 'Require' objects that should be
+         added/removed from the distribution.
+
+      'remove' -- a string or list of strings naming packages to be removed
+         from the distribution if this feature is *not* included.  If the
+         feature *is* included, this argument is ignored.  This argument exists
+         to support removing features that "crosscut" a distribution, such as
+         defining a 'tests' feature that removes all the 'tests' subpackages
+         provided by other features.  The default for this argument is an empty
+         list.  (Note: the named package(s) or modules must exist in the base
+         distribution when the 'setup()' function is initially called.)
+
+      other keywords -- any other keyword arguments are saved, and passed to
+         the distribution's 'include()' and 'exclude()' methods when the
+         feature is included or excluded, respectively.  So, for example, you
+         could pass 'packages=["a","b"]' to cause packages 'a' and 'b' to be
+         added or removed from the distribution as appropriate.
+
+    A feature must include at least one 'requires', 'remove', or other
+    keyword argument.  Otherwise, it can't affect the distribution in any way.
+    Note also that you can subclass 'Feature' to create your own specialized
+    feature types that modify the distribution in other ways when included or
+    excluded.  See the docstrings for the various methods here for more detail.
+    Aside from the methods, the only feature attributes that distributions look
+    at are 'description' and 'optional'.

+Six supports every Python version since 2.5.  It is contained in only one Python
