+;;; Commentary:
+
+;; NOTE: This is an add-on module for Riece.
+
+;; This add-on allows you to define aliases for IRC names.
+
+;; For example, if you want to define an alias `#r' for `#riece', you
+;; can customize riece-alias-alist as follows:
+;; (setq riece-alias-alist '(("#riece" . "#r")))
+
