# This script installs the puppet modules required by infra to run acceptance
# tests. It can run in two different contexts. In the first case, it is running
# as part of a zuul driven check/gate queue where it needs to opportunisticly
# install patches to repositories that are not landed yet. In the second case,
# it is running from a base virtual machine by the beaker tooling where it needs
# to install master of all openstack-infra repos and the tagged versions of all
# library modules.

# This script uses system-config/modules.env as the source of truth for modules
# to install. It detects the presence of zuul-cloner to decide if we are running
# in a zuul environment or not.
