THIS IS NOT A STAND-ALONE APPLICATION!
You need BW-Go or BW-Go Free version 4.5.0 or higher to use this plugin.
BW-GnuGo is a Gnu Go computer player service for the BW-Go and BW-Go Free applications. Use this service to play against the well known Gnu Go 3.8 bot player from within the BW-Go interface.
After installing this bot, you can use it just as any other tool within BW-Go, located in the play/review tool menu. You can save your game, edit it, and continue from where you left off - or from any other point. You can even use the bot on games you saved previously, or downloaded from other players!
