[gtp] stderr

IMO debugging commands are not needed in the protocol. Everyone can add his/her extensions. A program is free to send output to files/pipes/network -connecions, if it wants to. Or stderr. But stdin/stdout are supposed to obey the standard, which basically says: one line commands -->> responses, ended by empty line. BTW. I have been working on a NNGS<-->gtp gateway which can be controlled via nngs talk/tell. It could dump it's stderr to a NNGS channel (which could be restricted to the operator) In gunnar's case, this is of course nonsense -controlling a machine that is located on his desk via NNGS- , but it is an elegant way to interact with a *playing* go- playing-program. (it *could* be used for cheating: the turk on the desk :-)) AvK
