Description: You have to choose one source server to copy all talks from (OUT_SERVER in %cfg) and other server to paste (IN_SERVER in %cfg) all from source. Looks like some irc 'spy'.
See code's %cfg to understand it better.

You can use some commands on IN_CHANNEL:
!say bla # will say bla to OUT_CHANNEL
!me bla # action say on OUT_CHANNEL
!sayto nick bla # will say bla to nick on OUT_SERVER
!list # will list all OUT_CHANNEL users
!whois nick # whois nick on OUT_SERVER
!nick newnick # change nick on OUT_SERVER


* can transcode between various codepages
* use local IP addr
