[help-gengetopt] wishlist: mandatory parameters

[T]

Hi

I found that gengetopt is very useful. However, I wish it can
handle (at least document) mandatory parameters as well. 

By "mandatory parameter" I don't mean setting the required field as
required for "option", but real parameters. like for command cp:

 cp [options] <source> <dest>

the "source" & "dest". 

Any comment? 

thanks
