 This seems like a lot of text for the --help line, and it's just
telling you want the default getopt_long() style option parsing is does.
Also I'd assume most wouldn't be putting the output directly onto the
command line, but instead into kickstart or something.

 ACK, if you really want. But I'd just close NaB or something.
