-Date: 2012-08-14
-Initial Package Version: 8.0.4
-Upstream Status: Not applicable
-Origin: Based on dj's original patch.
-Description: This patch adds two GL demos, glxinfo and glxgears.
- It is based on dj's original patch, with refreshed demos
- from upstream git repository, with fixed compiling when
- shared libglapi is present and fixed installation process
- that won't run install -c on DESTDIR/usr/bin if directory
- exists.
