碁プログラムのためのフレームワークを提供してくれるみたい。以下、readme より。

I designed OpenGo to support Go engines in general. The idea
is to share the following things (at least):
+ user interfaces,
+ program-to-program communication (go modem protocol, igs, etc),
+ common algorithms (e.g. zobrist hashing)
+ multiple-simultaneous games (multi-threading of engines & interfaces)
+ repeated play and evaluation of engines
+ machine learning support
+ reading & writing common go file formats (ishi, sgf, etc.)
+ common rule systems
+ common go opponents for testing (e.g. wally)
