    // another option, usage(), which is an exception to the rule. This should only be used when
    // the default usage string automatically generated by clap doesn't suffice.
    //
    // You also set all the valid arguments your App should accept via the arg() and args() (a
    // well as subcommands via the subcommand() and subcommands() methods) which will be covered
    // later.
    //
    // Once all options have been set, call .get_matches() in order to find all valid command line
    // arguments that supplied by the user at runtime. The name given to new() will be displayed
    // when the version or help flags are used.
