      Usage: $0 [command] [options]

      Commands:

      up -  Builds the images, creates the application containers
            and starts the services based on the docker-compose.yml file.

            You can pass in a list of containers to start.
            By default all containers will be started.

            The API_URL used by tob-web can also be redirected.

            Examples:
            $0 start
            $0 start alice-agent

      start - Same as up

      restart - Re-starts the application containers,
                useful when updating one of the container images during development.

            You can pass in a list of containers to be restarted.
            By default all containers will be restarted.

            Examples:
            $0 start
            $0 start faber-agent

      logs - Display the logs from the docker compose run (ctrl-c to exit).

      stop - Stops the services.  This is a non-destructive process.  The volumes and containers
             are not deleted so they will be reused the next time you run start.

      down - Brings down the services and removes the volumes (storage) and containers.
      rm - Same as down
