24 ;; This add-on allows you to define aliases for IRC names.
26 ;; To use, add the following line to your ~/.riece/init.el:
27 ;; (add-to-list 'riece-addons 'riece-alias)
29 ;; For example, if you want to define an alias `#l' for `#Liece', you
30 ;; can customize riece-alias-alist as follows:
31 ;; (setq riece-alias-alist '(("#Liece" . "#l")))
