9 The \fIcloudlife\fP program draws a cellular
10 automaton based on Conway's Life, except that
11 cells have a maximum age, and only one pixel per
12 cell is drawn every tick.
15 accepts the following options:
18 Draw on a newly-created window. This is the default.
21 Draw on the root window.
24 If on a color display, pretend we're on a monochrome display.
27 Install a private colormap for the window.
29 .B \-visual \fIvisual\fP
30 Specify which visual to use. Legal values are the name of a visual class,
31 or the id number (decimal or hex) of a specific visual.
33 .B \-cycle-delay \fIinteger\fP
34 Time in microseconds to sleep between ticks. Default 25000.
36 .B \-cycle-colors \fIinteger\fP
37 How many ticks should elapse between cycling colors. 0 to disable
38 color cycling. Default 2.
40 .B \-cycle-colors \fIinteger\fP
41 How many ticks should elapse between cycling colors. 0 to use
42 just one color. Default 1.
44 .B \-ncolors \fIinteger\fP
45 How many colors should be used (if possible). Default 32.
46 The colors are chosen randomly.
48 .B \-cell-size \fIinteger\fP
49 Size of each cell, in powers of 2. Default 3 (8-pixel cells).
51 .B \-initial-density \fIinteger\fP
52 Percentage of cells that are alive at start and when the
53 field is repopulated. Default 30.
55 .B \-max-age \fIinteger\fP
56 Maximum age for a cell. Default 64.
63 to get the default host and display number.
66 to get the name of a resource file that overrides the global resources
67 stored in the RESOURCE_MANAGER property.
