+0.6.5	Support for non GNUC++ compilers.
+	
+0.6.4	fixed that get-hit-and-then-doubleclick bug
+
+	fixed a bug that caused the computer to switch sides if no
+	computer move is possible instead of getting another human move
+
+0.6.3	sound fix: when the animation is finished, the correct piece gets
+	redrawn before doing a sound-sync (how could I ever believe 0.6.2
+	would be the last change :-)
+
+0.6.2   animation fixed (hope this will be the last change)
+
+0.6.1   fixed that newly introduced highscore bug
+	computer continues now if a game was saved while thinking
+
+0.6:	better integration into new FSSTND

+	locale-strings changed - partial translation required for
+	other languages than english and german

+This file describes the overall design of KReversi.  Some of the
+classes have different names at this point, but that is indicated by a
+(now: XXX) tag.  These names will be changed when the KDE project has
+converted from CVS to Subversion since Subversion has so much better
+support for renaming files and directories.
+
+Almost all of the classes hold more members than are mentioned here,
+but those are implementation details and would only obscure the
+overall picture.  This file is only to give a helicopter view of the
+program, not to serve as detailed documentation.

+
+ReversiPosition (now: Position)
+    Holds a Reversi position.  This is the object that implements the
+    Reversi rules.
+
+
+ReversiMove (now: Move)
+    A move in a Reversi game.  
+
+
+ReversiGame (now: Game)
+    Holds all the moves of the game being played.  
+    Contains: ReversiPosition	Holds the current position.
+              Move[60]
+    FIXME: Remove the ReversiPosition and let it be implicit?
+    FIXME: Implement variations (later)
+
+
+Engine
+    Can generate a move, given a ReversiPosition.
+
+
+QReversiGame
+    The "document" for KReversi.
+    Handles a game being played and sends signals to all its views
+    when something changes.  Basically, the only difference between
+    this class and the more basic ReversiGame is that it sends signals
+    to the views.
+    Inherits: ReversiGame	The actual game being played
+
+
+QReversiGameView (status: PLANNED)
+
+    Shows a view of a complete game.  Currently this comprises a board
+    view, a listbox with a list of the moves, two status widgets
+    showing the current score.
+
+    Contains: *QReversiBoardView
+	      *QListBox
+	      *StatusWidget (two of them)
+
+
+QReversiBoardView
+
+    A view for a Reversi board.  The rest of the game view is
+    implemented in the class QReversiGameView.
+
+    Inherits: QWidget.
+    Contains: *QReversiGame	(not owner)
+
+    FIXME: Enhance the view with timing information, clock, etc.
+
+
+KReversi
+    The main class for the KReversi program
+    Contains: KActions
+	      *QReversiGame 	 (owner)
+	      *KReversiGameView  (owner)
+	      *Engine            (owner)
+              Statusbar
+
+    FIXME: Let the class also own two players.
+
+
+EngineView (status: PLANNED)
+    View of the internal thought processes of an Engine (trace, etc).
+    
+
+Some notes

+
+// The class Engine produces moves from a Game object through calls to the
+// function ComputeMove().
+//
+// First of all: this is meant to be a simple example of a game playing
+// program. Not everything is done in the most clever way, particularly not
+// the way the moves are searched, but it is hopefully made in a way that makes
+// it easy to understand. The function ComputeMove2() that does all the work
+// is actually not much more than a hundred lines. Much could be done to
+// make the search faster though, I'm perfectly aware of that. Feel free
+// to experiment.
+//
+// The method used to generate the moves is called minimax tree search with
+// alpha-beta pruning to a fixed depth. In short this means that all possible
+// moves a predefined number of moves ahead are either searched or refuted
+// with a method called alpha-beta pruning. A more thorough explanation of
+// this method could be found at the world wide web at http:
+// //yoda.cis.temple.edu:8080/UGAIWWW/lectures96/search/minimax/alpha-beta.html
+// at the time this was written. Searching for "minimax" would also point
+// you to information on this subject. It is probably possible to understand
+// this method by reading the source code though, it is not that complicated.
+//
+// At every leaf node at the search tree, the resulting position is evaluated.
+// Two things are considered when evaluating a position: the number of pieces
+// of each color and at which squares the pieces are located. Pieces at the
+// corners are valuable and give a high value, and having pieces at squares
+// next to a corner is not very good and they give a lower value. In the
+// beginning of a game it is more important to have pieces on "good" squares,
+// but towards the end the total number of pieces of each color is given a
+// higher weight. Other things, like how many legal moves that can be made in a
+// position, and the number of pieces that can never be turned would probably
+// make the program stronger if they were considered in evaluating a position,
+// but that would make things more complicated (this was meant to be very
+// simple example) and would also slow down computation (considerably?).
+//
+// The member m_board[10][10]) holds the current position during the
+// computation. It is initiated at the start of ComputeMove() and
+// every move that is made during the search is made on this board. It should
+// be noted that 1 to 8 is used for the actual board, but 0 and 9 can be
+// used too (they are always empty). This is practical when turning pieces
+// when moves are made on the board. Every piece that is put on the board
+// or turned is saved in the stack m_squarestack (see class SquareStack) so
+// every move can easily be reversed after the search in a node is completed.
+//
+// The member m_bc_board[][] holds board control values for each square
+// and is initiated by a call to the function private void SetupBcBoard()
+// from Engines constructor. It is used in evaluation of positions except
+// when the game tree is searched all the way to the end of the game.
+//
+// The two members m_coord_bit[9][9] and m_neighbor_bits[9][9] are used to
+// speed up the tree search. This goes against the principle of keeping things
+// simple, but to understand the program you do not need to understand them
+// at all. They are there to make it possible to throw away moves where
+// the piece that is played is not adjacent to a piece of opposite color
+// at an early stage (because they could never be legal). It should be
+// pointed out that not all moves that pass this test are legal, there will
+// just be fewer moves that have to be tested in a more time consuming way.
+//
+// There are also two other members that should be mentioned: Score m_score
+// and Score m_bc_score. They hold the number of pieces of each color and
+// the sum of the board control values for each color during the search
+// (this is faster than counting at every leaf node).
+//
+
+// The classes SquareStackEntry and SquareStack implement a
+// stack that is used by Engine to store pieces that are turned during
+// searching (see ComputeMove()).
+//
+// The class MoveAndValue is used by Engine to store all possible moves
+// at the first level and the values that were calculated for them.
+// This makes it possible to select a random move among those with equal
+// or nearly equal value after the search is completed.

+
+// The class Engine produces moves from a Game object through calls to the
+// function ComputeMove().
+//
+// First of all: this is meant to be a simple example of a game playing
+// program. Not everything is done in the most clever way, particularly not
+// the way the moves are searched, but it is hopefully made in a way that makes
+// it easy to understand. The function ComputeMove2() that does all the work
+// is actually not much more than a hundred lines. Much could be done to
+// make the search faster though, I'm perfectly aware of that. Feel free
+// to experiment.
+//
+// The method used to generate the moves is called minimax tree search with
+// alpha-beta pruning to a fixed depth. In short this means that all possible
+// moves a predefined number of moves ahead are either searched or refuted
+// with a method called alpha-beta pruning. A more thorough explanation of
+// this method could be found at the world wide web at http:
+// //yoda.cis.temple.edu:8080/UGAIWWW/lectures96/search/minimax/alpha-beta.html
+// at the time this was written. Searching for "minimax" would also point
+// you to information on this subject. It is probably possible to understand
+// this method by reading the source code though, it is not that complicated.
+//
+// At every leaf node at the search tree, the resulting position is evaluated.
+// Two things are considered when evaluating a position: the number of pieces
+// of each color and at which squares the pieces are located. Pieces at the
+// corners are valuable and give a high value, and having pieces at squares
+// next to a corner is not very good and they give a lower value. In the
+// beginning of a game it is more important to have pieces on "good" squares,
+// but towards the end the total number of pieces of each color is given a
+// higher weight. Other things, like how many legal moves that can be made in a
+// position, and the number of pieces that can never be turned would probably
+// make the program stronger if they were considered in evaluating a position,
+// but that would make things more complicated (this was meant to be very
+// simple example) and would also slow down computation (considerably?).
+//
+// The member m_board[10][10]) holds the current position during the
+// computation. It is initiated at the start of ComputeMove() and
+// every move that is made during the search is made on this board. It should
+// be noted that 1 to 8 is used for the actual board, but 0 and 9 can be
+// used too (they are always empty). This is practical when turning pieces
+// when moves are made on the board. Every piece that is put on the board
+// or turned is saved in the stack m_squarestack (see class SquareStack) so
+// every move can easily be reversed after the search in a node is completed.
+//
+// The member m_bc_board[][] holds board control values for each square
+// and is initiated by a call to the function private void SetupBcBoard()
+// from Engines constructor. It is used in evaluation of positions except
+// when the game tree is searched all the way to the end of the game.
+//
+// The two members m_coord_bit[9][9] and m_neighbor_bits[9][9] are used to
+// speed up the tree search. This goes against the principle of keeping things
+// simple, but to understand the program you do not need to understand them
+// at all. They are there to make it possible to throw away moves where
+// the piece that is played is not adjacent to a piece of opposite color
+// at an early stage (because they could never be legal). It should be
+// pointed out that not all moves that pass this test are legal, there will
+// just be fewer moves that have to be tested in a more time consuming way.
+//
+// There are also two other members that should be mentioned: Score m_score
+// and Score m_bc_score. They hold the number of pieces of each color and
+// the sum of the board control values for each color during the search
+// (this is faster than counting at every leaf node).
+//
+
+// The classes SquareStackEntry and SquareStack implement a
+// stack that is used by Engine to store pieces that are turned during
+// searching (see ComputeMove()).
+//
+// The class MoveAndValue is used by Engine to store all possible moves
+// at the first level and the values that were calculated for them.
+// This makes it possible to select a random move among those with equal
+// or nearly equal value after the search is completed.

+// 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).

+  I. Convert KReversi to a proper Model/View program.
+     1. Fix a ReversiGame (formerly known as Game)			DONE
+        - Clean it up. (Only store the moves).
+        - Add a few necessary methods.
+     2. Move all the slots for KActions to kreversi.cpp			DONE
+     3. Move the ownership of the engine and the game to kreversi.	DONE
+     4. Create a new class QReversiGame, that inherits ReversiGame	DONE
+	and sends a lot of signals.
+        - Split out a lot of methods from the current class Board.	done
+     5. Create QReversiBoardView from the rest of the current Board	DONE
+        - Clean it							done
+
+  II. Introduce a class ReversiPlayer
+
+  III. Convert everything to KGame
+     1. Let KReversiGame inherit from KGame
+     2. Let ReversiPlayer inherit from KPlayer.
+
+  IV. ...
+
+  V.  Profit!
+
+
+
+
+Old TODO items, partially done/not done
+=======================================
+
+* undo/redo
+	undo works, but I'll probably do not make a redo function
+
+* Sound support:
+  I'm not happy with
+  the sound files I have so if
+  you have better sounds, mail them to me 
+  (uuencoded). I need sounds for the following actions:
+	- game won
+	- game lost
+	- game drawn
+	- turning a piece
+	- putting a piece
+	- something for the hall of fame (trumpets???)
