;;; Commentary:
;; This file implements links to an IRC session from within Org-mode.
;; Org-mode loads this module by default - if this is not what you want,
;; configure the variable `org-modules'.
;;
;; Please customize the variable `org-default-extensions' to select
;; extensions you would like to use, and to deselect those which you don't
;; want.
;;
;; Please note that at the moment only ERC is supported. Other clients
;; shouldn't be difficult to add though.
;;
;; Then set `org-irc-link-to-logs' to non-nil if you would like a
;; file:/ type link to be created to the current line in the logs or
;; to t if you would like to create an irc:/ style link.
;;
;; Links within an org buffer might look like this:
;;
;; [[irc:/irc.freenode.net/#emacs/bob][chat with bob in #emacs on freenode]]
;; [[irc:/irc.freenode.net/#emacs][#emacs on freenode]]
;; [[irc:/irc.freenode.net/]]
;;
;; If, when the resulting link is visited, there is no connection to a
;; requested server then one will be created.
