         * These methods are shorthand versions of the ones above.
         * For the most part, this is a hack.
         * But, it is a useful one.
         * When new users start using your console program, they need help getting started.
         * This is why I recommend using descriptive names for your command-methods.
         * But, when your users become more familiar with the program, they will want terser commands.
         * They will no longer need their hand holding. This is where these alias-commands come in.
