+SUMMARY="High performance 3D graphics toolkit"
+DESCRIPTION="
+The OpenSceneGraph is an open source high performance 3D graphics toolkit,
+used by application developers in fields such as visual simulation, games,
+virtual reality, scientific visualization and modelling. Written entirely
+in Standard C++ and OpenGL it runs on all Windows platforms, OSX, GNU/Linux,
+IRIX, Solaris, HP-Ux, AIX and FreeBSD operating systems. The OpenSceneGraph
+is now well established as the world leading scene graph technology, used
+widely in the vis-sim, space, scientific, oil-gas, games and virtual reality
+industries.
