              [-mag integer] [-term string]


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


       -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.


       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.


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


       The data files for the initial states supplied  with  this

       program  were  lifted and converted from the excellent and
       free program xlife.
