long-description=
 VirtualGL is an open source toolkit that gives any Unix or Linux remote display software
 the ability to run OpenGL applications with full 3D hardware acceleration. 
 With VirtualGL, the OpenGL commands and 3D data are directed to the remote host  3D graphics accelerator ( "GPU") in the application server,
 and only the rendered 3D images are sent to the client machine.
