Taken from the cgoban page CGoban ("Complete Goban") provides a large set of go-related services for Unix and X11. A list of the functions that it provides: * Play go against another player. When playing a game locally, you have a choice of rule sets and time controls. I made a strong attempt at implementing the rule sets as precisely as possible: + Chinese rules have a true Superko rule. + Japanese rules correctly recognize seki and award no points. + Japanese rules let you locally resolve disputes at the end of the game. * Edit and view SGF files. CGoban provides full functionality for editing and viewing SGF files. * Connect to a go server over the internet. CGoban can connect to NNGS or IGS and gives a convienent graphical user interface to the server. * Act as a bridge to go modem protocol. Go modem protocol has become a standard way for computer go programs to communicate. CGoban can let you connect to devices (such as modems) speaking go modem protocol, act as a graphical board for programs that speak go modem protocol out of stdin/stdout, or connect programs to one of the internet go servers. NOTE: The default Go server, IGS, has moved from igs.nuri.net to igs.joyjoy.net. If you already have a .cgobanrc file from before cgoban 1.9.2-6 in your home directory, it probably has the old address for igs. Please replace all occurrences of "igs.nuri.net" in that file with "igs.joyjoy.net" to make it work correctly. Richard Braakman
