"""Run Python's test suite in a fast, rigorous way.

The defaults are meant to be thorough but to skip certain resources are not
used (by default) which can consume a lot of time and resources (e.g.,
largefile) or can be distracting (e.g., audio and gui). These defaults
can be overridden by simply passing arguments to this script.
