Usage:
------
-LD_PRELOAD=./libgliar.so <opengl_executable>

+Note: The library can only restrict the capabilities of a GPU, not "emulate" non supported extensions for
+example. If the gliar.conf contains an extension that is not supported by the user's real GPU, the library
+will return a warning and the user's program might crash.
