jitro is a bot wrapper jac has made to facilitate him in the creation of ever more IRC bots.

Basic features include connecting to multiple networks, joining several channels and then running the actual bot binary. This means that jitro can multiplex multiple IRC connections onto a single binary.
But wait, that's not all!
jitro can also run multiple backend binaries at once. This means that text can come from multiple IRC networks and channels, go out to multiple secondary binaries which process and react to the text, and then be funneled back to IRC.

Both PINKSERV2 and porygit currently utilize jitro. EArndt's bot, O'Malley also used jitro.
