# Usage: normalize_acl.py acl.config [transformation [transformation [...]]]
#
# Transformations:
# 0 - dry run (default, print to stdout rather than modifying file in place)
# 1 - strip/condense whitespace and sort (implied by any other transformation)
# 2 - get rid of unneeded create on refs/tags
# 3 - remove any project.stat{e,us} = active since it's a default or a typo
# 4 - strip default *.owner = group Administrators permissions
# 5 - sort the exclusiveGroupPermissions group lists
# 6 - replace openstack-ci-admins and openstack-ci-core with infra-core
