Usage: $(basename "$0") <cmd>
For publish, if you want to push the spec to the spec cache, provide a path to a service account key file that can write to the cache.
Available commands:
  scaffold
  test <integration_root_path>
  build  <integration_root_path> [<run_tests>]
  publish  <integration_root_path> [<run_tests>] [--publish_spec_to_cache] [--publish_spec_to_cache_with_key_file <path to keyfile>]
  publish_external  <image_name> <image_version>
