Re: [wxhaskell-devel] CPP to FFI

[Blair A. <mrb...@gm...>]

Ah I see. I'm still looking through the wxHaskell code to see if there is
any work I think I can do (as a beginner!) and thought id give this a
mention.

I agree that SWIG is a great tool! Hopefully they get their summer of code
working.

Many thanks,
Blair
