$program [OPTIONS] launch-loop INSTANCE

launch-loop INSTANCE

    Launches the instance with specified name in a loop. Instance will

    be relaunched every time it exits. Useful for mod development. To

    stop the loop, send SIGTERM to Factorio instance (or just press

    CTRL-C). See the note for the "create" command.
