the OpenGL Utility Toolkit (GLUT) library.  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,
widely available and highly portable.

GLUT (and hence freeglut) 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.  Freeglut is released under
the X-Consortium license.")
