Hi

nice to hear about the new gengetopt version.
I kindly ask what's about this groupoption refactoring?

It means I may except this feature will be included, too:

The check is performed at compile time by gengetopt while the others at runtime by the generated source. This way a default group option (groupdefault?) will behave exactly the same as if it were specified by the user at commandline. Am I right?

Btw, default group option resembles to "flag on" a little bit however makes much more sense because to make default one of option from a mutually exlcusive group makes sense ;)

I remember now that some gengetopt users were asking in the list how to deal with more than one .ggo files each one defining options of different "subcommands" to the application. If default group option (groupdefault in short) was implemented such subcommands (with their multiple .ggo files) may be converted into a single .ggo file. Not always but sometimes it can be very handy...
