Run this shell script several times to    see what happens.    There are a number of data files available:	dgibson.data1	dgibson.data2	dgibson.data3	dgibson.data4	dgibson.data5    For dgibson.data5 you will need a large screen, lots of virtual    memory and lots of time!    Good luck trying to use a debugger on this entry!  Life is not    always pretty.Selected notes from the author:    This program plays the Game of Life.    Life is a cellular automaton invented by J. H. Conway, in which each of    a rectangular grid of cells can be alive or dead, and cells with more    than 3 or less than 2 (out of 8) live neighbours die, and empty cells    with exactly 3 neighbours give birth.    Some notes: the "STAT n" information does not have to be present in the    initial configuration;  the initial configuration should not have live    cells around the edges; the grid should be a perfect rectangle.    Further features: the current generation number is preserved, and the    grid automatically resizes itself as the object gets too big or too    small.	When writing this program, my goal was to make each cell in the life	grid expand to the code which calculates the fate of that cell.  In	addition, the resulting program is a single expression, which makes it	necessary to recurse on main in two "directions" simultaneously.
