+                   Tcl-DP: Tic Tac Toe
+
+This creates a simple distributed Tic Tac Toe game, displayed using 
+Tk widgets.  It is an example of using a Tcl-DP distributed object.
+
+  playerX.tcl	-- script for player X, must be run first
+  playerO.tcl	-- script for player O, must be run after playerX.tcl
+
+The following two files are shared by player X and player O.
+
+  board.tcl	-- definition of the distributed board class
+  interface.tcl	-- definition of user interface of Tk widgets
+
+--------------------------------------------------------------------
+
+First, start player X...
+
+Run wish.
+Type "source playerX.tcl" and answer the questions;
+
+--------------------------------------------------------------------
+
+Second, start player O...
+
+Run wish, as another process.
+Type "source playerO.tcl" and answer the questions;

+
+Player X is the RPC server.  Player O is the RPC client.  (Hence,
+player X must be set up before player O.)  Player X creates a Tic
+Tac Toe board object, which gets distributed to player O.  Each
+player process locally updates its Tk interface, as the Tk
+widgets of the interface are not distributed objects.
+
+Because the board is a distributed object, callbacks from user
+actions are very simple.  Any changes to slots of the board
+object in a callback are automatically propagated to all
+processes.
