SUMMARY = "A free implementation of the OpenGL API"
DESCRIPTION = "Mesa is an open-source implementation of the OpenGL specification - \
a system for rendering interactive 3D graphics.  \
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 is used as part of the overall Direct Rendering Infrastructure and X.org \
environment."
