              [-mag integer] [-term string]

DESCRIPTION

       Simulate  Conway's  Game  of Life with an arbitrary set of
       initial conditions.  Input files need to  be  in  the  PBM
       file format.

OPTIONS

       -width integer
              Width of the plot in pixels.

       -height integer
              Height of the plot in pixels.

       -extra integer
              Number of extra border pixels.

       -wrap  Wrap around world?

       -infile string
              Initial configuration file

       -steps integer
              Number of time steps to simulate.

       -inv   Invert all colors?

       -mag integer
              Magnification factor.

       -term string
              How to plot points.

MISCELLANY

       You  will need to use the -extra option in conjuction with
       the -wrap option if you wish to  simulate  moving  objects
       that  tend to fly off in one direction.  Periodic patterns
       may need the -extra option to give them a  little  bit  of
       extra room to work in.

BUGS

       No  sanity  checks  are performed to make sure that any of
       the options make sense.
