Bug 335691

+++ This bug was initially created as a clone of Bug #304781 +++

In preperation for the Games Live DVD, I've created a small bash script which
resides in opengl-games-utils, which is meant to be used as a wrapper around
OpenGL games. If DRI is available this wrapper does nothing, if it isn't it will
show an error dialog, explaining about Free Software and 3D drivers and then exit.

The idea here is that an error dialog is better then trying to click the quit
menu option while the mouse is jumping from the right edge of the screen to the
left edge (mouse navigation is anything but easy at 3 fps).

This is esp. important for the Games Live DVD, as there people will not have
those other <beep> drivers available.

Adding the wrapper is _really_ easy:

1) Add: "Requires: opengl-games-utils"
2) Add to %install:
"ln -s opengl-game-wrapper.sh $RPM_BUILD_ROOT%{_bindir}/%{name}-wrapper"
3) Add "%{_bindir}/%{name}-wrapper" to %files
4) Change the .desktop file Exec entry from "%{name}" to "%{name}-wrapper"

This all assumes your main binary name == %{name}, otherwise adapt as necessary.

If you already have a wrapper script for one reason or the other, you can
incorperate the checkDriOk function directly into your wrapper, no need todo a
wrapper wrapper, see vegastrike's vegastrike-wrapper.sh CVS file as example.
