;;; Commentary:
|
|
|
|
;; This allows us to customize an `erc-autojoin-channels-alist'. As
|
|
;; we /JOIN and /PART channels, this alist is updated to reflect our
|
|
;; current setup, so that when we reconnect, we rejoin the same
|
|
;; channels. The alist can be customized, so that the customized
|
|
;; value will be used when we reconnect in our next Emacs session.

Customize this variable to set the value for your first connect.
