"""setuptools/distutils command to run testr via setup.py
PBR will hook in the Testr class to provide "setup.py test" when
.testr.conf is present in the repository (see pbr/hooks/commands.py).
If we are activated but testrepository is not installed, we provide a
sensible error.
You can pass --coverage which will also export PYTHON='coverage run
--source <your package>' and automatically combine the coverage from
each testr backend test runner after the run completes.
