# This is the map of API name aliases to actual API names.
# Do not add to this map unless the api definition uses different names for api
# name, endpoint and/or collection names.
# The apis_map keys are aliases and values are actual API names.
# The rest of the Cloud SDK, including
# property sections, and command surfaces should use the API name alias.

# The general rule for this module is: all apis_map lookups should use the real
# API name, and all property lookups should use the alias. Any api_name argument
# expects to receive the name alias (if one exists). The _GetApiNameAndAlias
# helper method can be used to convert it into a (name, alias) tuple.
# TODO(b/31163851): remove the need for this alias map.
