+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.
