.subcommand(
        Command::new("print")
            .alias("p")
            .arg(arg!(<address>  "address of value to print"))

                    .arg(arg!(pointe: -p   "pointer"))
                    .required(true),
            )
            .about("delete breakpoint")
            .help_template(APPLET_TEMPLATE),
    )
