It's really coincidental that I've had some thoughts about enabling
SSL in cl-irc. Although that was related to DCC sessions. I don't
think the IRC protocol lends itself for secure communications, but
well, since I already figured out how to do it for DCC, I thought I'd
add it for normal IRC connections too.

Thanks for providing the patch. To prevent the duplication, I did it
somewhat differently. See
http://trac.common-lisp.net/cl-irc/changeset/203 for how I did it.

Anyway, for how to use it:

(require :cl-irc)
(require :cl+ssl)

(connect :server <your server>
               :port <port num>
               :connection-security :ssl)

That's all!

No idea. Which Lisp implementation are you using? (Not all of them
support IPv6 (yet?))

Erik.
