| 8 | .SH DESCRIPTION |
|---|
| 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. |
|---|
| 13 | .SH OPTIONS |
|---|
| 14 | .I cloudlife |
|---|
| 15 | accepts the following options: |
|---|
| 16 | .TP 8 |
|---|
| 17 | .B \-window |
|---|
| 18 | Draw on a newly-created window. This is the default. |
|---|
| 19 | .TP 8 |
|---|
| 20 | .B \-root |
|---|
| 21 | Draw on the root window. |
|---|
| 22 | .TP 8 |
|---|
| 23 | .B \-mono |
|---|
| 24 | If on a color display, pretend we're on a monochrome display. |
|---|
| 25 | .TP 8 |
|---|
| 26 | .B \-install |
|---|
| 27 | Install a private colormap for the window. |
|---|
| 28 | .TP 8 |
|---|
| 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. |
|---|
| 32 | .TP 8 |
|---|
| 33 | .B \-cycle-delay \fIinteger\fP |
|---|
| 34 | Time in microseconds to sleep between ticks. Default 25000. |
|---|
| 35 | .TP 8 |
|---|
| 36 | .B \-cycle-colors \fIinteger\fP |
|---|
| 37 | How many ticks should elapse between cycling colors. 0 to disable |
|---|

|---|
| 39 | .TP 8 |
|---|
| 40 | .B \-cycle-colors \fIinteger\fP |
|---|
| 41 | How many ticks should elapse between cycling colors. 0 to use |
|---|
| 42 | just one color. Default 1. |
|---|
| 43 | .TP 8 |
|---|
| 44 | .B \-ncolors \fIinteger\fP |
|---|
| 45 | How many colors should be used (if possible). Default 32. |
|---|
| 46 | The colors are chosen randomly. |
|---|
| 47 | .TP 8 |
|---|
| 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. |
|---|
| 54 | .TP 8 |
|---|
| 55 | .B \-max-age \fIinteger\fP |
|---|
| 56 | Maximum age for a cell. Default 64. |
|---|
| 57 | |

| 59 | .SH ENVIRONMENT |
|---|
| 60 | .PP |
|---|
| 61 | .TP 8 |
