The generator currently creates C++ headers but maybe it could be 
extended for pure C headers.

There are some remaining bugs / limitations:
- Cannot create separate header files, only only big header (run 
dmd for each module instead)
- some D features are not implemented yet
- some D Features generate wrong headers
- the header format could be improved

That being said it‘s certainly usable and will probably improve a 
lot once people start  contributing through  PRs.

PS: Refer to the dshell test in my PR for a runnable example.
