;;; Commentary:
;; Internet Relay Chat (IRC) is a form of instant communication over
;; the Internet. It is mainly designed for group (many-to-many)
;; communication in discussion forums called channels, but also allows
;; one-to-one communication.
;; Rcirc has simple defaults and clear and consistent behavior.
;; Message arrival timestamps, activity notification on the modeline,
;; message filling, nick completion, and keepalive pings are all
;; enabled by default, but can easily be adjusted or turned off. Each
;; discussion takes place in its own buffer and there is a single
;; server buffer per connection.
;; Open a new irc connection with:
;; M-x irc RET
;;; Todo:
