Several people asked how to run applications that expect GL with Ygl.

You can do this without relinking the app if you have shared libraries
and if the app does only require the routines emulated by Ygl:

With /usr/lib/libYgl.a, make a symbolic link like the following:

$ ln -s /usr/lib/libYgl.a /tmp/libgl.a

Then find out how to reset the shared libraries search path on your
OS; under AIX 3.2 (ksh) do:

$ export LIBPATH=/tmp:/lib:/usr/lib

Now you can try to start the application. If you receive error
messages like "symbol xyz in ksh is undefined", than it won't work,
because the application uses GL routines xyz that are not emulated by
Ygl...
