# Many of neutron's repos suffer from the problem of depending on neutron,
# but it not existing on pypi. -- Well, that's the usual issue, but in
# neutron's case, we want to import tempest directly for the api tests.
# This wrapper for tox's package installer will use the existing package
# if it exists, else use zuul-cloner if that program exists, else grab it
# from neutron master via a hard-coded URL. That last case should only
# happen with devs running unit tests locally.
