[help-gengetopt] option group with exclusion

[Gyozo, PAPP (VBuster)]

Hi there,

currently I'm struggling to implement an interface which is basically a 
mutually exlcusive group of option with a little exception two of the four 
options are allowed to appear at the same time.

Consider the following situation, there are 4 options:

--all-files
--pattern
--include
--exclude

the rules which cannot be changed because this was what the customer wanted 
actually:
1.)--all-files should not be used neither of the remaining 3 options.
2.)--pattern should not be used neither of the remaining 3 options.
3.) BUT --exclude and --include can be used at the same time.

Apart from the last term this could be easily implemented as a option group. 
But how to modify gengetopt to be able to handle such a situation? I've added 
some code around gengetopt calls in my application, but I feel it is worth 
discussing this problem. May gengetopt address such functionality, too?
