if let Some(cmd) = app.command() {
    match cmd.as_str() {
        "start" => {
            dbg!(app.value("--config"));
        }
        "help" => {
            app.print_help();
        }
        "version" => {
            app.print_version();
        }
        _ => {
            app.print_error_try("help");
