+
+XBoard is an X11/R4-based user interface for GNU Chess. It uses the R4 Athena
+widgets and Xt Intrinsics to provide an interactive referee for managing a
+chess game between a user and a computer opponent or between two computers.
+You can also use XBoard without a chess program to play through games in files
+or to play through games manually (force mode); in this case, moves aren't
+validated by XBoard. XBoard manages a digital chess clock for each player and
+resets the clocks if the proper number of moves are played within the time
+control period. A game can be started with the initial chess position, with a
+series of moves from a game file or with a position from a position file. The
+"match" shell script runs a series of games between two machines, alternating
+sides. The man page xboard.man describes the features of XBoard.
+
+XBoard was originally written by Dan Sears and Chris Sears. XBoard borrows its
+colors, icons and piece bitmaps from XChess, which was written and copyrighted
+by Wayne Christopher. We thank him for his work on XChess. Beginning with
+version 2.0, Tim Mann has taken over development of XBoard.

+your changes to Tim and Stuart.
+
+CAVEATS
+
+XBoard depends on the R4 Xt Intrinsics and R4 Athena Widget Set. In
+particular, R3 just won't do---XBoard uses features introduced in R4. The
+standard DEC and SUN releases won't do either. The Athena widgets are either
+missing in the DEC standard distribution or in the wrong (R3) place in SUN
+OpenWindows.
+
+XBoard works best with version 4.0 of GNU Chess. (Older versions may also
+work, but they are unsupported. The GNU Chess project requests that you get a
+current copy of GNU Chess rather than using older, bug-ridden versions.) GNU
+Chess must be compiled with the -DXBOARD flag for use with XBoard. Use the
+"make gnuchessx" target in GNU Chess 4.0 to do this.
+
+The Free Software Foundation would prefer to be able to distribute an X
+chessboard program covered only by the GNU General Public License and
+unencumbered by any other copyright. If you can help with this, please
