# Transformations:

# all Apply all 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
|
|
# 7 - add at least one core team, if no team is defined with special suffixes
|
|
# like core, admins, milestone or Users
