# Which libraries should we install from git instead of using released
# versions on pypi?
#
# By default DevStack is now installing libraries from pypi instead of
# from git repositories by default. This works great if you are
# developing server components, but if you want to develop libraries
# and see them live in DevStack you need to tell DevStack it should
# install them from git.
#
# ex: LIBS_FROM_GIT=python-keystoneclient,oslo.config
#
# Will install those 2 libraries from git, the rest from pypi.
