+.SH DESCRIPTION
+The \fIgflux\fP program draws a colourfull animated rippling square rotating in 3D space.
+.SH OPTIONS
+.I gflux
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-squares \fInum\fP\fP
+Specifies the size of the grid in squares. default 19
+.TP 8
+.B \-resolution \fInum\fP\fP
+Specifies the wireframe detail of the squares. default 4
+.TP 8
+.B \-mode \fImode\fP\fP
+Specifies the draw method: wireframe; solid (meaning a solid colored
+surface); light (same as solid, but with lighting effects);
+checker (a texture-mapped checkerboard pattern); or grab (meaning
+grab an image to manipulate.)
+
+When grabbing images, the image will be grabbed from the portion of
+the screen underlying the window, or from the system's video input,
+or from a random file on disk, as indicated by
+the \fIgrabDesktopImages\fP, \fIgrabVideoFrames\fP,
+and \fIchooseRandomImages\fP options in the \fI~/.xscreensaver\fP
+file; see
+.BR xscreensaver-demo (1)
+for more details.
+.TP 8
+.B \-wireframe
+Same as "-mode wire".
+.TP 8
+.B \-flat \fInum\fP\fP
+0 for smooth shading 1 for flat. default 0
+.TP 8
+.B \-speed \fInum\fP\fP
+Specifies speed of ripples flowing over the surface. default 0.05
+.TP 8
+.B \-rotationx \fInum\fP \-rotationy \fInum\fP \-rotationz \fInum\fP\fP
+Specifies the speed of rotation of the surface in these axis 
+.TP 8
+.B \-waves \fInum\fP\fP
+Specifies the number of ripple centres at any one time.  Values should be greater than 1.  default 3
+.TP 8
+.B \-waveChange \fInum\fP\fP
+Specifies the duration of a ripple centre.  after this they fade away to be reborn elsewhere with a different frequency. default 50
+.TP 8
+.B \-waveHeight \fInum\fP\fP
+Specifies the height of ripples on the surface. default 1.0
+.TP 8
+.B \-waveFreq \fInum\fP\fP
+Specifies the maximum frequency of ripples. default 3.0
+.TP 8
+.B \-zoom \fInum\fP\fP
+Specifies the size of the viewport. Smaller values fill the screen with rippling surface. default 1.0
+.TP 8
+.B \-delay \fImicroseconds\fP
+How long to pause between frames.  Default is 20000, or 0.02 second.
+.TP 8
+.B \-fps
+Display the current frame rate, CPU load, and polygon count.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.
