"""Run tests.
This will find all modules whose name match a given prefix in the test
directory, and run them. Various command line options provide
additional facilities.
Command line options:
-v verbose -- run tests in verbose mode with output to stdout
-q quiet -- don't print anything except if a test fails
-t testdir -- directory where the tests will be found
-x exclude -- add a test to exclude
-p profile -- profiled execution
-d dbc -- enable design-by-contract
-m match -- only run test matching the tag pattern which follow
If no non-option arguments are present, prefixes used are 'test',
'regrtest', 'smoketest' and 'unittest'.
