+.SH NAME
+glxgears \- ``gears'' demo for GLX
+.SH SYNOPSIS
+.B glxgears
+.RI [ options ]
+.SH DESCRIPTION
+The \fIglxgears\fP program is a port of the ``gears'' demo to GLX. It displays
+a set of rotating gears and prints out the frame rate at regular intervals. It
+has become quite popular as basic benchmarking tool.
+.SH OPTIONS
+.TP 8
+.B \-display \fIdisplay\fP
+Specify which X display to run on.
+.TP 8
+.B \-stereo
+Use a stereo enabled GLX visual.
+.TP 8
+.B \-samples \fIN\fP
+Run in multisample mode with at least N samples.
+.TP 8
+.B \-fullscreen
+Run in fullscreen mode.
+.TP 8
+.B \-info
+Display OpenGL renderer information.
+.TP 8
+.B \-geometry \fIWxH+X+Y\fP
+Window geometry.

+.RI [ options ]
+.SH DESCRIPTION
+The \fIglxinfo\fP program shows information about the OpenGL and GLX
+implementations running on a given X display.
+.PP
+The information includes details about the server- and client-side GLX
+implementation, the OpenGL and GLU implementations as well as a list
+of available GLX visuals.
+.SH OPTIONS
+.TP 8
+.B \-v
+Print visuals info in verbose form.
+.TP 8
+.B \-t
+Print verbose table.
+.TP 8
+.B \-display \fIdisplay\fP
+Specify the X display to interrogate.
+.TP 8
+.B \-h
+Print usage information.
+.TP 8
+.B \-i
+Force an indirect rendering context.
+.TP 8
+.B \-b
+Find the "best" visual and print its number.
+.TP 8
+.B \-l
+Print interesting OpenGL limits.
+.TP 8
+.B \-s
+Print a single extension per line.
