+ * Many thanks to Mr. Luthman who has allowed me to put this port
+ * under the GNU GPL. Without his wonderful game engine kreversi
+ * would be just another of those Reversi programs a five year old
+ * child could beat easily. But with it it's a worthy opponent!

+// The class Game represents a complete or incomplete Othello game. It uses
+// the classes Score and Move (and internally  Position).
+// You can make moves, take back one move at a time, reset to initial position
+// and get certain data on the current position.
+
+//  Public functions:
+
+//  public Game()
+//     Creates a game with the initial position.
+
+//  public void Reset()
+//     Resets to the initial position.
+
+//  public boolean MakeMove(Move m)
+//     Makes the move m. Returns false if the move is not legal or when called
+//     with a move where the player is Score.NOBODY.
+
+//  public boolean TakeBackMove()
+//     Takes back a move. Returns true if not at the initial position.
+
+//  public int GetSquare(int x, int y)
+//     Returns the piece at (x, y). Returns Score.NOBODY if the square is not
+//     occupied.
+
+//  public int GetScore(int player)
+//     Returns the score for player.
+
+//  public Move GetLastMove()
+//     Returns the last move. Returns null if at the initial position.
+
+//  public boolean MoveIsLegal(Move m)
+//     Checks if move m is legal.
+
+//  public boolean MoveIsPossible(int player)
+//     Checks if there is a legal move for player.
+
+//  public boolean MoveIsAtAllPossible()
+//     Checks if there are any legal moves at all.
+
+//  public int GetMoveNumber()
+//     Returns move number.
+
+//  public int GetWhoseTurn()
+//     Returns the player in turn to play (if there are no legal moves
+//     Score.NOBODY is returned).
+
+//  public Move[] TurnedByLastMove()
+//     Returns a vector of the squares that were changed by the last move.
+//     The move that was actually played is at index 0. At the initial
+//     position the length of the vector returned is zero. (Could be used
+//     for faster updates of a graphical board).
