+SUMMARY="Multi-platform GL implementation"
+DESCRIPTION="Mesa is an open-source implementation of the OpenGL specification - a system for rendering interactive 3D graphics.
 
-DESCRIPTION="Mesa3D is a multi-platform GL implementation"
-HOMEPAGE="http://www.freedesktop.org/" 
+A variety of device drivers allows Mesa to be used in many different environments ranging from software emulation to complete hardware acceleration for modern GPUs.
+
+Mesa ties into several other open-source projects: the Direct Rendering Infrastructure and X.org to provide OpenGL support to users of X on Linux, FreeBSD and other operating systems."
