+      The Mesa project began as an open-source implementation of the OpenGL
+      specification - a system for rendering interactive 3D graphics. Over the
+      years the project has grown to implement more graphics APIs, including
+      OpenGL ES (versions 1, 2, 3), OpenCL, OpenMAX, VDPAU, VA API, XvMC, and
+      Vulkan.  A variety of device drivers allows the Mesa libraries to be used
+      in many different environments ranging from software emulation to
+      complete hardware acceleration for modern GPUs.
