+      FreeGLUT is an open source alternative to the OpenGL Utility Toolkit
+      (GLUT) library. 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
+      intended to be a full replacement for GLUT, and has only a few
+      differences.
