Yes, I read about the plans. Before that is being implemented it is
always possible to use
cmake or some other tool to generate out the .ggo files.

You understood me perfectly.

Not really.

Yes, you are probably right. I think I will use my own struct instead.
If I for instance later want to publish an open source library, there
better be no dependencies on gengetopt in the functions of the library.
