I looked again at the patch to the setup.py, and saw some whitespace
fixups in it.  Here is the diff for another pacakge without any

- - The first change is not strictly required, but it does get the 'test*'
  attributes captured in a separate file in the EGG-INFO directory,
  which makes it at least theoretically possible to run the tests from
  a binary egg (not that I ever use them).

- - The second is what allows 'setup.py test' to work, running only the
  non-layer tests.  The 'tests_require' part gets zope.testing
  downloaded and on the path before looking for the loader specified
  in 'test_loader'.  That loader then gets passed the 'test_suite'

- - The last section of the diff is what gets a new command available
  ('setup.py ftest').  That is the part which runs all the tests, both
  unit and functional.

If we chose to make the entry point 'test' instead of 'ftest', then
we could leave out the middle section, but would need to make
'zope.testing' a 'setup_requires' dependency.  That case is also the one
where running from a fresh checkout requires 'setup.py egg_info' first,
or else the old testrunner gets used the first time.  I think that we
are OK for distributed tarballs, because they contain the '.egg-info'
directory generated during 'sdist'.
