Usage: vglrun [options] [--] <OpenGL app> [OpenGL app arguments]

VirtualGL options
-c <c>    : proxy = Send 3D images uncompressed using X11 transport
            jpeg = Compress 3D images using JPEG/send using VGL transport
            rgb = Encode 3D images as RGB/send using VGL transport
            sr = Compress 3D images using DPCM/send using Sun Ray transport
            srlossless = Encode 3D images as RGB/send using Sun Ray transport
-cl <d>   : <d> = The hostname or IP address of the VirtualGL client (or
                  Sun Ray server)
-dl       : Force apps that dlopen() libGL to load VirtualGL instead
-d <d>    : <d> = the X Display or GLP device to use for 3D rendering
-fps <f>  : Limit client/server frame rate to <f> frames/sec
+/-g      : Enable/disable gamma correction
-gamma <g>: Set gamma correction factor to <g> (see docs)
-mc <c>   : jpeg = Store movie frames as JPEG images
            rgb = Store movie frames as RGB images
-movie <f>: Record a movie file <f> containing the images generated by
            VirtualGL
-mq <q>   : JPEG compression quality for movie frames [1 <= <q> <= 100]
-msamp <s>: JPEG chrominance subsampling factor for movie frames
            [<s> = 0 (grayscale), 1, 2, or 4]
-np <n>   : Use <n> CPUs to perform image compression (VGL transport only)
-p <p>    : TCP port to use when connecting to vglclient (VGL transport only)
+/-pr     : Enable/disable performance profiling output
-q <q>    : JPEG compression quality [1 <= <q> <= 100]
+/-s      : Enable/disable SSL encryption of VGL image transport
-samp <s> : JPEG chrominance subsampling factor
            [<s> = 0 (grayscale), 1, 2, 4, 8, or 16]
+/-sp     : Turn on/off frame spoiling
-st <s>   : left = Send only left eye buffer
            right = Send only right eye buffer
            quad = Use quad-buffered stereo if available, otherwise use
                   red/cyan (anaglyphic) stereo [default]
            rc = Always use red/cyan (anaglyphic) stereo
+/-sync   : Enable/disable strict 2D/3D synchronization
+/-tr     : Enable/disable function call tracing (generates a lot of output)
+/-v      : Enable/disable verbose VirtualGL messages
-64       : (Solaris only) Preload VirtualGL only into 64-bit apps
-32       : (Solaris only) Preload VirtualGL only into 32-bit apps


Note that the "vglrun -c 0" interface still works with this release, but 
it is undocumented.  The documented interface is "vglrun -c proxy".
