;;; Commentary:

;; This Circe module provides some often-used chanop commands. I was
;; very reluctant to add this. None of these commands will make it in
;; the core, or even be provided by default. You should have to go to
;; great lengths to use them.

;; Always remember the Tao of IRC:
;;
;;     IGNORE is the weapon of an IRC knight. Not as clumsy or as
;;     random as a kickban.
