I don't know what your "unnamed options" means exactly. I search for the
keyword "unnamed" in the manual but didn't find anything. Anyway, I meant:

Currently, gengetopt only handle switches. The usage message is:

  Usage: sample1 [OPTIONS]...

  -h, --help              Print help and exit
      --full-help         Print help, including hidden options, and exit

I want, with the help of "mandatory parameter", it can be:

  Usage: sample1 [OPTIONS]... SOURCE DEST

  SOURCE mandatory parameter to ...
  DEST ... copy SOURCE to DEST

  -h, --help              Print help and exit
      --full-help         Print help, including hidden options, and exit

or something like that.

Hope I've made it clearer this time.

thanks
