        cloudlife - a cellular automaton based on Conway's Life


        cloudlife  [-display  host:display.screen]  [-foreground color] [-back-
        ground color] [-window] [-root]  [-mono]  [-install]  [-visual  visual]
        [-ncolors  integer]  [-cycle-delay  microseconds]  [-cycle-colors inte-
        ger][-cell-size integer] [-initial-density integer] [-max-age integer]


        The cloudlife 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.


        cloudlife accepts the following options:
        -window Draw on a newly-created window.  This is the default.
        -root   Draw on the root window.
        -mono   If on a color display, pretend we're on a monochrome display.
                Install a private colormap for the window.
        -visual visual
                Specify which visual to use.  Legal values are the  name  of  a
                visual  class,  or the id number (decimal or hex) of a specific
        -cycle-delay integer
                Time in microseconds to sleep between ticks.  Default 25000.
        -cycle-colors integer
                How many ticks should elapse between cycling colors.  0 to dis-
                able color cycling.  Default 2.
        -ncolors integer
                How many colors should be used (if possible).  Default 64.  The
                colors are chosen randomly.
        -cell-size integer
                Size of each cell, in powers of 2.  Default 3 (8-pixel  cells).
        -initial-density integer
                Percentage  of cells that are alive at start and when the field
                is repopulated.  Default 30.
        -max-age integer
                Maximum age for a cell.  Default 64.
        -fps    Display the current frame rate and CPU load.


        DISPLAY to get the default host and display number.
                to get the name of a resource file that  overrides  the  global
                resources stored in the RESOURCE_MANAGER property.
