* `->requires(opt)`: This option requires another option to also be present, opt is an `Option` pointer.
* `->excludes(opt)`: This option cannot be given with `opt` present, opt is an `Option` pointer.
* `->envname(name)`: Gets the value from the environment if present and not passed on the command line.
* `->group(name)`: The help group to put the option in. No effect for positional options. Defaults to `"Options"`. `"Hidden"` will not show up in the help print.
* `->group(name)`: The help group to put the option in. No effect for positional options. Defaults to `"Options"`. `""` will not show up in the help print (hidden).
* `->ignore_case()`: Ignore the case on the command line (also works on subcommands, does not affect arguments).
* `->take_last()`: Only take the last option/flag given on the command line, automatically true for bool flags
* `->check(CLI::ExistingFile)`: Requires that the file exists if given.

* `.prefix_command()`: Like `allow_extras`, but stop immediately on the first unrecognised item. It is ideal for allowing your app or subcommand to be a "prefix" to calling another app.
* `.set_footer(message)`: Set text to appear at the bottom of the help string.
* `.group(name)`: Set a group name, defaults to `"Subcommands"`. Setting `""` will be hide the subcommand.
> Note: if you have a fixed number of required positional options, that will match before subcommand names.
