-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.
+The plugin can be used as a viewer for several types of configuration
+files.  The plugin should be able to open most configurations with the
+following extensions: \fname{.cells}, \fname{.l}, \fname{.lif}, \fname{.life}
+and \fname{.rle}.
 
-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.
+Just ``play'' a supported file and the game configuration stored in it will be
+loaded into this plugin.  There is support for reading alternate rule sets from
+Life 1.05 and RLE configurations.
 
+All supported configuration files are plain text files.  A description of
+several configuration formats can be found at
+\url{http://psoup.math.wisc.edu/mcell/ca_files_formats.html}.
