Log Message:
Updated py-setuptools to 32.1.0.

v32.1.0
-------

* #891: In 'test' command on test failure, raise DistutilsError,
  suppression invocation of subsequent commands.

v32.0.0
-------

* #890: Revert #849. ``global-exclude .foo`` will not match all
  ``*.foo`` files any more. Package authors must add an explicit
  wildcard, such as ``global-exclude *.foo``, to match all
  ``.foo`` files. See #886, #849.

v31.0.1
-------

* #885: Fix regression where 'pkg_resources._rebuild_mod_path'
  would fail when a namespace package's '__path__' was not
  a list with a sort attribute.

v31.0.0
-------

* #250: Install '-nspkg.pth' files for packages installed
  with 'setup.py develop'. These .pth files allow
  namespace packages installed by pip or develop to
  co-mingle. This change required the removal of the
  change for #805 and pip #1924, introduced in 28.3.0 and implicated
  in #870, but means that namespace packages not in a
  site packages directory will no longer work on Python
  earlier than 3.5, whereas before they would work on
  Python not earlier than 3.3.
