;;; Commentary:

;; Requiring this file will make ERC react to CTCP PAGE messages
;; received, and it will provide a new /PAGE command to send such
;; messages yourself.  To enable it, customize the variable
;; `erc-page-mode'.

;;; Code:

(require 'erc)

;;;###autoload (autoload 'erc-page-mode "erc-page")

with six arguments: PROC NICK LOGIN HOST TO MSG.  Note that you can
