+Bootstrapper for nose/pytest plugins.
+
+The entire rationale for this system is to get the modules in plugin/
+imported without importing all of the supporting library, so that we can
+set up things for testing before coverage starts.
+
+The rationale for all of plugin/ being *in* the supporting library in the
+first place is so that the testing and plugin suite is available to other
+libraries, mainly external SQLAlchemy and Alembic dialects, to make use
+of the same test environment and standard suites available to
+SQLAlchemy/Alembic themselves without the need to ship/install a separate
+package outside of SQLAlchemy.
+
+NOTE:  copied/adapted from SQLAlchemy master for backwards compatibility;
+this should be removable when Alembic targets SQLAlchemy 1.0.0.
