# For help and usage information, simply execute the script w/o any arguments.
#
-# This script is intended to be run by podman developers who need to debug
-# problems specifically related to Cirrus-CI automated testing. However,
-# because it's only loosely coupled to the `.cirrus.yml` configuration, it must
-# orchestrate VMs in GCP directly. This means users need to have
-# pre-authorization (access) to manipulate google-cloud resources. Additionally,
-# there are no guarantees it will remain in-sync with other automation-related
-# scripts. Therefore it may not always function for everybody in every
-# future scenario without updates/modifications/tweaks.
-#
-# When successful, you will end up connected to a GCP VM with with a clone of
-# the upstream podman repository 'master' branch, using a remote named 'origin'.
-# If you want to customize this behavior, you will want to use a "hook" script.
-# Please use this example carefully, since git setups vary by person, you
-# will probably need to make local edits.

+# This script is intended to be run by Red Hat podman developers who need

+# with supervision upon request.
