"""Run Python's test suite in a fast, rigorous way.
The defaults are meant to be reasonably thorough, while skipping certain
tests that can be time-consuming or resource-intensive (e.g. largefile),
or distracting (e.g. audio and gui). These defaults can be overridden by
simply passing a -u option to this script.
