d7330d0f44
Primary reason for this change was to update the spec and setup files from basic setuptools to use pbr This allows the autogenerated /usr/bin/system file to directly call the main method without using pkg-resources. This will provide a performance improvement of .5 seconds per CLI call, once the other pkg_resources issues are resolved Second reason for this change was to wire in the tox unit tests. This also includes pep8, pylint and coverage. Currently pep8 does not perform the 80 char limit check Currently pylint still reports some issues This should not affect the RPM names being generated or otherwise affect patching or upgrades.
