;;; Commentary:
;; This is an extension module for Circe. It creates what I think is
;; a more minimalistic view of Circe buffers. It right-aligns all the
;; nicks, right-justifies and simplifies certain messages. It takes
;; care of both `fill-prefix' and `wrap-prefix' so it should be usable
;; with and without `lui-fill-type'.
;; The name circe-serenity was chosen because I think the buffers feel
;; cleaner and more serene with this setup.
