# Makefile to build XGL 3.2 example programs.

# If OpenWindows and XGL are not in their default
# locations, then the environment variables OPENWINHOME
# and XGLHOME must be set before using this Makefile.
# Default locations:

#   OpenWindows - /usr/openwin
#   XGL 3.2     - /opt/SUNWits/Graphics-sw/xgl
