pbmlife - apply Conway's rules of Life to a portable bitmap
This program is part of Netpbm(1).
pbmlife reads a portable bitmap as input, applies the rules of Life to it for one generation, and produces a PBM image as output.
A white pixel in the image is interpreted as a live beastie, and a black pixel as an empty space.
