Configuration:
  --scope <url>  
            Specify the authentication a method should be executed in. Each scope requires
            the user to grant this application permission to use it.
            If unset, it defaults to the shortest scope url for a particular method.
  --config-dir <folder>
            A directory into which we will store our persistent data. Defaults to a user-writable
            directory that we will create during the first invocation.
            [default: ~/.google-service-cli]
