Facebook is open-sourcing warp, a fast C and C++ preprocessor
written by Walter Bright.
All I can say is two things.
One I'm annoyed because I've been working on a macro preprocessor
the last week or so and just got it up to supporting #if's anding
and oring with defines.
Second great work on collaborating with Facebook. Definitely a
great thing going on here!
