27 ;; Internet Relay Chat (IRC) is a form of instant communication over
28 ;; the Internet. It is mainly designed for group (many-to-many)
29 ;; communication in discussion forums called channels, but also allows
30 ;; one-to-one communication.
32 ;; Rcirc has simple defaults and clear and consistent behavior.
33 ;; Message arrival timestamps, activity notification on the mode line,
34 ;; message filling, nick completion, and keepalive pings are all
35 ;; enabled by default, but can easily be adjusted or turned off. Each
36 ;; discussion takes place in its own buffer and there is a single
37 ;; server buffer per connection.
