Re: [Help-gengetopt] Help about multiple options.

[Hakan Bayındır]

Hi Wolf,

There's no need to be sorry. This is not a deal breaker in any way. I 
just wanted to make my code behave similarly to the other tools I use 
regularly, but this is not a hard requirement.

There are already two different routines parsing the arguments by 
themselves for their needs, but parsing it once and centrally (via 
gengetopt), and distributing options to the respective libraries would 
be a better solution in the long run, anyway.

Thanks again for your quick answer,

Cheers,
H.
