+o Building Gallium3D rasterizer for Mesa
+  --------------------------------------
+
+The Gallium3D software rasterizer can be built to be used as an
+alternative to the default Mesa software rasterizer. For that, use
+the following command in the libGL build directory (the default is 
+/usr/xenocara/lib/libGL):
+
+ env XENOCARA_BUILD_GALLIUM=Yes make build
+
+This software rasertizer can also benefit from the LLVM infrastructure
+and use a special pipe if it is built with LLVM support. You will need
+to have the llvm package installed and use the following command in the
+libGL build directory:
+
+ env XENOCARA_BUILD_GALLIUM=llvm make build
+
+Alternatively, you can also set XENOCARA_BUILD_GALLIUM in /etc/mk.conf
+or in your environment.
