+# Upstream pip vendorizes a bunch of its dependencies.  Debian de-vendorizes
+# (unbundles) these dependencies to be compliant with Debian policy.  Instead,
+# these dependencies are packaged as wheel (.whl) files in a known location.
+# When pip itself executes, we have to arrange for these wheels to show up
+# earlier on sys.path than any  other version of these packages, otherwise
+# things can break.  See for example Bug #744145.
+#
+# The location of the wheels differs depending on whether we're inside or
+# outside a virtual environment, regardless of whether that venv was created
+# with virtualenv or pyvenv.  The first thing we have to do is figure out if
+# we're inside or outside a venv, then search the appropriate wheel directory
+# and add all the .whls found there to the front of sys.path.  As per Debian
+# Python Policy, only the wheels needed to support this de-vendorization will
+# be present, so it's safe to add them all.
+#
+# venv determination is a bit of a black art, but this algorithm should work
+# in both Python 2 (virtualenv-only) and Python 3 (pyvenv and virtualenv).  -

+    # Special case pip and setuptools to generate versioned wrappers
+    #
+    # The issue is that some projects (specifically, pip and setuptools) use
+    # code in setup.py to create "versioned" entry points - pip2.7 on Python
+    # 2.7, pip3.3 on Python 3.3, etc. But these entry points are baked into
+    # the wheel metadata at build time, and so if the wheel is installed with
+    # a *different* version of Python the entry points will be wrong. The
+    # correct fix for this is to enhance the metadata to be able to describe
+    # such versioned entry points, but that won't happen till Metadata 2.0 is
+    # available.
+    # In the meantime, projects using versioned entry points will either have
+    # incorrect versioned entry points, or they will not be able to distribute
+    # "universal" wheels (i.e., they will need a wheel per Python version).
+    #
+    # Because setuptools and pip are bundled with _ensurepip and virtualenv,
+    # we need to use universal wheels. So, as a stopgap until Metadata 2.0, we
+    # override the versioned entry points in the wheel and generate the
+    # correct ones. This code is purely a short-term measure until Metadat 2.0
+    # is available.
+    #
+    # To add the level of hack in this section of code, in order to support
+    # ensurepip this code will look for an ``ENSUREPIP_OPTIONS`` environment
+    # variable which will control which version scripts get installed.
+    #

+    #   - Only pipX.Y and easy_install-X.Y will be generated and installed
+    # ENSUREPIP_OPTIONS=install
