The original Mah-Jong game
This is a set of programs to play the original Mah-Jong game: one server, one client for a human player and one client for an AI player. Hence the game can be played by 1 to 4 human players.
You should keep in mind that the original Mah-Jong game has nothing to do with the well-known solitaire game. (It merely uses the same set of tiles.)
