|

|
|
;; 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")
