This is a patched version of xboard-3.2.pl2, so that it can
play draughts against the program dragon. The source code has
been left intact as far as possible. The object of these patches
is to provide a minimal interface to 'dragon', not to provide
a beatiful fully operative interface.

Several menu entries are not available; they still operate but
generate useless results. I have left these in the program so
that they can be supported at a later time.

About the source code changes:
Some new commands have been introduced to communicate with
'dragon'. In particular all stuff associated with  legal moves
has been handed over to dragon.

Promotion code has been commented out. Some code used the
value '8' rather than BOARD_SIZE.

All changes in the code are marked with /* mdg */ so they
are easy to look up.
