+The :mod:`test` package can be run as a script to drive Python's regression
+test suite, thanks to the :option:`-m` option: :program:`python -m test`. Under
+the hood, it uses :mod:`test.regrtest`; the call :program:`python -m
+test.regrtest` used in previous Python versions still works).
+Running the script by itself automatically starts running all regression
tests in the :mod:`test` package. It does this by finding all modules in the
package whose name starts with ``test_``, importing them, and executing the
function :func:`test_main` if present. The names of tests to execute may also
be passed to the script. Specifying a single regression test (:program:`python
-regrtest.py test_spam.py`) will minimize output and only print
+-m test test_spam`) will minimize output and only print
whether the test passed or failed and thus minimize output.

resources; specifying ``all`` as an option for ``-u`` enables all
possible resources. If all but one resource is desired (a more common case), a
comma-separated list of resources that are not desired may be listed after
-``all``. The command :program:`python -m regrtest -uall,-audio,-largefile`

-options, run :program:`python -m regrtest -h`.

Some other ways to execute the regression tests depend on what platform the
tests are being executed on. On Unix, you can run :program:`make test` at the
