\subsection{Rocklife}

This an implementation of J. H. Conway's Game of Life (see
\url{http://en.wikipedia.org/wiki/Conway%27s_Game_of_Life} for a detailed
description).

Rockbox can open files with a configuration description (\fname{.cells} files).
Just ``play'' such file and the game configuration stored in it will be loaded
into this plugin.

A \fname{.cells} file is a text file. A capital `O' marks a live cell, a dot
marks a dead cell, all other characters are ignored. Everything on a line
starting with an exclamation sign (and including it) is a comment and is
ignored.
