freeglut is a completely OpenSourced alternative to the OpenGL Utility
Toolkit (GLUT) library written by Mark Kilgard.
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.
from tobias ulmer (MAINTAINER),
no objections from oga@, testing and ok sthen@
non-free glut will remain around for a while, but ports depending on glut
will be switched to freeglut in a few.
