+"""Regression test.
+
+This will find all modules whose name is "test_*" in the test
+directory, and run them.  Various command line options provide
+additional facilities.
+
+Command line options:
+
+-v: verbose -- print the name name of each test as it is being run
+-q: quiet -- don't print anything except if a test fails
+-g: generate -- write the output file for a test instead of comparing it
+-x: exclude -- arguments are tests to *exclude*
+
+If non-option arguments are present, they are names for tests to run,
+unless -x is given, in which case they are names for tests not to run.
+If no test names are given, all tests are run.
