+.SH NAME
+fluidballs - the physics of bouncing balls.
+.SH SYNOPSIS
+.B fluidballs
+[\-display \fIhost:display.screen\fP]
+[\-visual \fIvisual\fP]
+[\-window]
+[\-root]
+[\-count \fInumber\fP]
+[\-size \fInumber\fP]
+[\-gravity \fInumber\fP]
+[\-wind \fInumber\fP]
+[\-friction \fInumber\fP]
+[\-delay \fInumber\fP]
+[\-nonrandom]
+[\-no-shake]
+[\-fps]
+.SH DESCRIPTION
+Models the physics of bouncing balls, or of particles in a gas or fluid,
+depending on the settings. If "Shake Box" is selected, then every now and
+then, the box will be rotated, changing which direction is down (in order
+to keep the settled balls in motion.) 
+.SH OPTIONS
+.TP 8
+.B \-visual \fIvisual\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 \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-count \fInumber\fP
+How many balls to display.  Default: 300.
+.TP 8
+.B \-size \fInumber\fP
+Maximum size of each ball.  Default: 25.
+.TP 8
+.B \-gravity \fInumber\fP
+Coefficient of gravity.  Useful values are < 0.1.  Default: 0.01.
+.TP 8
+.B \-wind \fInumber\fP
+Wind.  Useful values are < 0.1.  Default: 0.00.
+.TP 8
+.B \-friction \fInumber\fP
+Coefficient of friction (or viscosity.)  Useful values are < 4.  Default: 0.8.
+.TP 8
+.B \-delay \fInumber\fP
+Per-frame delay, in microseconds.  Default: 10000 (0.01 seconds.).
+.TP 8
+.B \-nonrandom
+Make all balls be the same size.
+.TP 8
+.B \-no-nonrandom
+Make the balls be random sizes.  Default.
+.TP 8
+.B \-shake | \-no-shake
+Whether to shake the box if the system seems to have settled down.
+"Shake" means "change the direction of Down."
+.TP 8
+.B \-fps | \-no-fps
+Whether to show a frames-per-second display at the bottom of the screen.
+.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.
