"GLFW is a free, Open Source, multi-platform library for opening a window, 
creating an OpenGL context and managing input. It is easy to integrate into 
existing applications and does not lay claim to the main loop. GLFW is written 
in C and has native support for Windows, Mac OS X and many Unix-like systems 
using the X Window System, such as Linux and FreeBSD. GLFW is licensed under the 
zlib/libpng license."
