[Gate-users] How to compile a new geometry class?

[Andreas Menzel]

Dear David Sarrut, der David Boersma,

thanks a lot for your really quick and detailed answers.
 From a programming side, it turns out I had been doing exactly the 
right thing.
I just setup the necessary git(Hub) infrastructure and, thanks to your 
quick replies, I will see very soon if it works.

Thanks again!

Andreas Menzel
