+"""If you have Ned Batchelder's coverage_ module installed, you may activate a
+coverage report with the ``--with-coverage`` switch or NOSE_WITH_COVERAGE
+environment variable. The coverage report will cover any python source module
+imported after the start of the test run, excluding modules that match
+testMatch. If you want to include those modules too, use the ``--cover-tests``
+switch, or set the NOSE_COVER_TESTS environment variable to a true value. To
+restrict the coverage report to modules from a particular package or packages,
+use the ``--cover-package`` switch or the NOSE_COVER_PACKAGE environment
+variable.
