# This script store release meta information in the git repository for
# a project.  It does so on an isolated, hidden branch called
# refs/meta/openstack/release.  Because it's not under refs/heads, a
# standard clone won't retrieve it or cause it to show up in the list
# of remote branches.  The branch shares no history with the project
# itself; it starts with its own root commit.  Jenkins is permitted to
# push directly to refs/meta/openstack/*.
