The README says:
Koji is required but not available on pypi.python.org, we enabled system sitepackages for tox, so koji can be found while running tests.
it's available on PyPI now. 0d21605fd4a6ca45cbc032a8400f592587dd1f22 fixed this, the README still has the old information.
Please see the discussion at #328 about the challenges associated with maintaining this large README.
