;;; 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:
;;; Code:

The following parameters are recognized:
VALUE must be a string. If absent, `rcirc-default-nick' is used
for this connection.
VALUE must be a number or string. If absent,
`rcirc-default-port' is used.
VALUE is a boolean. If true, the connection will be established
using the tls.el library. If absent, `rcirc-default-use-tls' is
used, which in turn default to nil (false).
VALUE is a custom function to open the connection and must take
the same arguments of `open-network-stream' If you set this,
the :use-tls parameter is ignored (as you are supposed to set the
connection by yourself)
