Configuration:
  --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]
  --debug
            Output all server communication to standard error. `tx` and `rx` are placed into 
            the same stream.
  --debug-auth
            Output all communication related to authentication to standard error. `tx` and `rx` are placed into 
            the same stream.
