golly - 3.3-1.1+b2 main

Golly simulates Conway's Game of Life with an arbitrarily large grid
of cells. It can optionally use a hashlife algorithm, which allows
it to rapidly compute generations for huge patterns, and to compute
many generations into the future at a time.
.
Golly provides a graphical interface for viewing and editing cellular
automata. It supports copy and paste, zoom, auto-fit, multiple
layers, and viewing different areas of a pattern simultaneously in
different areas of a window.
.
Golly can load patterns from RLE, Life 1.05/1.06, dblife, and
macrocell file formats; it can also interpret images as Life
patterns. Golly provides integrated help, including a copy of the
Life Lexicon.
.
Golly also supports other rules for 2D cellular automata with an
8-cell neighborhood, and supports 1D cellular automata.
