;;; Commentary:

;; This file deals with IRC networks.
;;
;; Usage:
;;
;; This is the "networks" module.
;;
;; M-x erc-server-select provides an alternative way to connect to servers by
;; choosing networks.
;; You can use (eq (erc-network) 'Network) if you'd like to set variables or do
;; certain actions according to which network you're connected to.
;; If a network you use is not listed in `erc-networks-alist', you can put
;; (add-to-list 'erc-networks-alist '(Network "irc.server-name.net")) in your
;; config file.

;;; Code:

(require 'erc)
(eval-when-compile (require 'cl-lib))

;; Variables

(defgroup erc-networks nil
  "IRC Networks."
