+This module has a number of tests that raise different kinds of warnings.
+When the tests are run, the warnings are caught and their messages are printed
+to stdout.  This module also accepts an arg that is then passed to
+unittest.main to affect the behavior of warnings.
+Test_TextTestRunner.test_warnings executes this script with different
+combinations of warnings args and -W flags and check that the output is correct.
