I clarified that elsewhere.  It must be able to handle the offer, even if
it always says "draw declined".  It doesn't have to offer a draw, but if the
program can't, the operator should not be allowed to be a proxy.

However, the _player_ has to accept the draw.  In a game, if I am offered a
draw, I can't get up and go consult with someone before accepting or declining
the offer.  Computer rules are the same.  IE in USCF rules I can't do _anything_
on behalf of the program except make moves and enter moves and respond to
questions about "how much time is left on my clock  and how many moves until
the next time control?"
