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 certain features for developers of board game-playing engines for enhancing their programs.
