The grammars are for various 2D & 3D CAD model formats. Some can be fairly complicated, and the data files can be fairly large. For clarity, I'm bootstrapping something and don't have any immediate plans to open source the grammars. Certainly, it would be worth looking at Binspector. Probably it would take me a couple of days to get up to speed though, and that is not time that I have immediately.
