+"""Mandatory APIs checker
+
+This script retrieves the endpoint catalog from Keystone using the OpenStack
+SDK and checks whether all mandatory APi endpoints, are present.
+The script relies on an OpenStack SDK compatible clouds.yaml file for
+authentication with Keystone.
+As the s3 endpoint might differ, a missing one will only result in a warning.
