+ LibGGI driver for Mesa-3.0
+ by Uwe Maurer (uwe_maurer@t-online.de)
+
+
+Introduction
+============
+[from libggi.txt by Steve Cheng and Hartmut Niemann]
+
+ "LibGGI, the dynamic GGI (General Graphics Interface) library is a
+ flexible drawing library.
+
+ It provides an opaque interface to the display's acceleration
+ functions. It was originally intended to allow user programs to
+ interface with KGI, the kernel side of the GGI code, but other display
+ types can be easily used by loading the appropriate "display target"
+ (e.g. X, memory).
+
+ LibGGI consists of a main library (libggi.so) and a multitude of
+ dynamic drivers. The library then loads the necessary "drivers" for
+ the requested mode, taking hints from the graphics device if
+ necessary. LibGGI can also load extension libraries, e.g. to provide
+ enhanced 2D and 3D functions.
+
+ It has been designed after having a look at several existing
+ libraries, and so far we have found porting to be quite simple from
+ and to most of them."

+
+ More information about the GGI project and LibGGI can be
+ obtained from the GGI website:
+
+ www.ggi-project.org
+
+----------------------------------------------------------------------------
+
+Installation
+============
+
+ - Install LibGGI
+
+ - Unpack the Mesa archives
+
+ - In the Mesa directory type:
+
+ make linux-ggi
+ su
+ make linux-ggi-install
+ exit
+
+ - Now you can try some demos.
+ If they don't work, you can set the GGIMESA_DEBUG
+ variable to 255 and you will see some information from the
+ LibGGI-driver.
+
+ export GGIMESA_DEBUG=255
+
+
+GLUT
+====
+
+ You can change these default values in ggi/ggiglut.c:
+ #define WIDTH 640
+ #define HEIGHT 400
+ #define GRAPHTYPE_RGB GT_16BIT
+ #define GRAPHTYPE_INDEX GT_8BIT
+
+ Options:
+ -bpp x Set graphic mode with x bits per pixel
+ -size x y Screen (or window) is x*y pixels
+
+ Example:
+ demos/gears -size 320 200 -bpp 24
+
+Updates
+=======
+
+ You can find the latest LibGGI-driver and ggiglut on my
+ homepage:
