Quarry is a multi-purpose GUI for several board games, at present Go,
Amazons and Reversi (a.k.a. Othello.) It allows users to play against
computer players (third-party programs, e.g. GNU Go or GRhino) or
other humans, view and edit game records. Future versions will also
support Internet game servers and provide features for developers
of board game-playing engines for enhancing their programs.
