Is this what I think it is? :) It's a header/interface definition for AFM, right?
I don't think I have seen this file before, it's in /API/include/FM dir of the new 1.2.1 DCS World installation.
Does that mean that AFM is sort of public API now and not just for the official third-party developers? Everyone can try their hand at it? Or am I just dreaming?
Edit: It's a real deal. There is also a template Visual Studio project included!
