+.SH DESCRIPTION
+The \fIcloudlife\fP program draws a cellular
+automaton based on Conway's Life, except that
+cells have a maximum age, and only one pixel per
+cell is drawn every tick.
+.SH OPTIONS
+.I cloudlife
+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 \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.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 \-cycle-delay \fIinteger\fP
+Time in microseconds to sleep between ticks.  Default 25000.
+.TP 8
+.B \-cycle-colors \fIinteger\fP
+How many ticks should elapse between cycling colors.  0 to disable
+color cycling.  Default 2.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be used (if possible).  Default 64.
+The colors are chosen randomly.
+.TP 8
+.B \-cell-size \fIinteger\fP
+Size of each cell, in powers of 2.  Default 3 (8-pixel cells).
+.TP 8
+.B \-initial-density \fIinteger\fP
+Percentage of cells that are alive at start and when the
+field is repopulated.  Default 30.  
+.TP 8
+.B \-max-age \fIinteger\fP
+Maximum age for a cell.  Default 64.
+.TP 8
+.B \-fps
+Display the current frame rate and CPU load.
+.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.
