GLFW bindings for Chicken Scheme.
The source for this egg is available at Bitbucket.
Note that this extension applies to Version 2 of the GLFW library. For an interface to GLFW Version 3, see the glfw3 egg.
Constant & function names & signatures match those of GLFW.

The heavy lifting was done by Felix Winkelman's bind egg, I just fiddled with the header file and fixed up the output a bit. Bug reports should go to me, though.
