Hi gengetopt guys :)

Both groups and modes are powerful and useful.

But it seems ( at least to me ) that bringing the idea to the logical limit was to allow a certain option to be simultaneously a member of a mode and a group. This might be the simplest way to support "mutually exclusive groups of mutually exclusive options".

For example, I can't see how to have a certain mode of operation, where I can only select one option from among a group. To be fully expressive, an option would need to be in the cross product of a mode and a group, not either a mode or a group.

What would be your analysis? Any chance of adding this feature? I've marked it "4" because there is, of course, a workaround, but it is suboptimal, i.e. gengetopt related functionality of keeping options mutually exclusive would leak into the main program.

Thanks for your contributions to gengetopt,
