From 2179980ed660ef66a9c064d153c5de7994d431ab Mon Sep 17 00:00:00 2001
From: Kenneth Russel <kbrussel@alum.mit.edu>
Date: Wed, 25 Jun 2003 09:05:29 +0000
Subject: Split up net.java.games.util; moved GLUT and BufferUtils into
 net.java.games.jogl.util, and moved demo-specific utility classes into
 jogl-demos project under demos.util. Added nearly all JavaOne demos into
 jogl-demos project; rewrote where necessary to use
 ClassLoader.getResourceAsStream() instead of flat files, put into packages
 and added to Makefile. Added gleem to jogl-demos project. Added jogl.jar
 build rule.

git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/../svn-server-sync/jogl-demos/trunk@3 3298f667-5e0e-4b4a-8ed4-a3559d26a5f4
