1st of all, thanks for all your replies Lorenzo. It really gives a warm
feeling to a newcomer like me.

Oh, I didn't know that.

I meant the usage help message:

$ grep required sample0.ggo
option  "str-opt"         s "A string option, for a filename"      string 
typestr="filename"     required
option  "long-opt"        - "A long option"        long       required

$ gengetopt --show-help -i sample0.ggo | grep -- '[rg]-opt'
  -s, --str-opt=filename  A string option, for a filename
      --flag-opt          A flag option  (default=off)
      --long-opt=LONG     A long option
  -D, --dependant=INT     option that depends on str-opt

I think it is a good idea to indicate which options are required here also. 
E.g.,

      --long-opt=LONG     A long option (mandatory)

or something like that. 

what do you think?
