Description:

Internet Relay Jabber (or IRJ) is a Jabber client for IRC. It's useful
if you like IRC, but your friends use another IM service. It is
written in Perl and uses Net::Jabber and Net::IRC.

IRJ isn't a transport or a gateway between Jabber and IRC (ie, a
server component for many users). Basically what it does is connect to
both Jabber and IRC as regular users. It then acts as an IRC bot to
relay conversations in IRC to Jabber. It is meant for one user per IRJ
process and pretty much requires a dedicated IRC channel. It also
works best if you have access to a shell sever of some kind (so IRJ
can always be running in the background) and use an IRC server with
NickServ and ChanServ so you can restrict access to your IRJ channel.
