Re: [pbmserv-dev] Adding a command to a game

[Lyman Hurd <lhurd@yahoo.com>]

I must say that adding a command to game.cpp is an
ambitious step!  Given that sgf is a way to display a
game, perhaps you might be able to set up a game
option "I want to receive the game in sgf format" and
then override the displayboard method?  This would not
require any changes at the level of game.cpp (I could
help step through the steps it would take).

It has been a while since I looked at sgf.  Is it in
XML?
