Description:

GLFW is a free, Open Source, portable framework for OpenGL application
development. In short, it is a single library providing a powerful,
portable API for otherwise operating system specific tasks such as
opening an OpenGL window, and reading keyboard, mouse and joystick
input.

It also provides functions for reading a high precision timer,
accessing OpenGL extensions, creating and synchronizing threads,
reading textures from files and more.

GLFW is available for Windows, MacOS X, Unix-like systems such as
Linux and FreeBSD, and for AmigaOS and DOS.
