%description
%_name is a completely open source alternative to the OpenGL Utility Toolkit
(GLUT) library with an OSI approved free software license. GLUT was originally
written by Mark Kilgard to support the sample programs in the second edition
OpenGL 'RedBook'. Since then, GLUT has been used in a wide variety of practical
applications because it is simple, universally available and highly portable.

%_name allows the user to create and manage windows containing OpenGL
contexts on a wide range of platforms and also read the mouse, keyboard and
joystick functions.
