+************************************************************
+
+The Direct Rendering Manager (drm) is a device-independent kernel-level
+device driver that provides support for the XFree86 Direct Rendering
+Infrastructure (DRI).
+
+The DRM supports the Direct Rendering Infrastructure (DRI) in four major
+ways:
+
+ 1. The DRM provides synchronized access to the graphics hardware via
+ the use of an optimized two-tiered lock.
+
+ 2. The DRM enforces the DRI security policy for access to the graphics
+ hardware by only allowing authenticated X11 clients access to
+ restricted regions of memory.
+
+ 3. The DRM provides a generic DMA engine, complete with multiple
+ queues and the ability to detect the need for an OpenGL context
+ switch.
+
+ 4. The DRM is extensible via the use of small device-specific modules
+ that rely extensively on the API exported by the DRM module.
+
+
+Documentation on the DRI is available from:
+ http://dri.freedesktop.org/wiki/Documentation
+ http://sourceforge.net/project/showfiles.php?group_id=387
+ http://dri.sourceforge.net/doc/
