The difference is that humans can talk with each other to resolve
differences. Computers can't. So they must follow a stricter set of
Alain has it right. :) I don't see what will go wrong if you change your
program to implement the cleanup command correctly. The original email
game a log of what happened in a game that ended up wrongly scored, but
admits that the program hadn't followed the cleanup protocol fully. If
it did, then the game would have been correctly scored. So the problems
look to me to be in the program, not in the protocol.
