GNUGO - the game of Go (Wei-Chi)
Version 1.2 last revised 10-31-95
Copyright (C) Free Software Foundation, Inc.

Introduction
This program is a minor modification of the GNUGO (Version 1.1). Main
change in this version is the removing of any system dependent functions
to conform to ISO Standard C (ANSI C). This software is an attempt to
distribute a free program to play Go. The idea of this program is based
on the article "Programming the Game of Go. Byte, Vol.6 No.4" by
J. K. Millen.
Currently, this program only understands basic Go rules and skills.
It counts the number of liberty for each board piece. Computer move is
generated by choosing among several possible moves to attack the opponent,
defense own pieces and match playing patterns. If no good move is found
then random move will be generated. It doesn't have the concept of eye
although it will try to form one.
The program is written in C running on UNIX and DOS in TTY mode. A
variation of this program NeXTGo running on NeXTStep has been developed
by John Neil (neil@math.mth.pdx.edu). Future versions of this program
will include graphical user interfaces on X-Window and MS-Windows
systems.
You are encouraged to send in enhencement, suggestion, bug/fix for this
program. Future release can be obtained from Free Software Foundation.
