Egg-based discovery test loader.
This plugin implements nose2's automatic test module discovery inside Egg Files.
It looks for test modules in packages whose names start
with 'test', then fires the :func:`loadTestsFromModule` hook for each
one to allow other plugins to load the actual tests.
It also fires :func:`handleFile` for every file that it sees, and
:func:`matchPath` for every python module, to allow other plugins to
load tests from other kinds of files and to influence which modules
are examined for tests.
