;;; Commentary:

;; This package lets you add behavior (which we call "piece of advice") to
;; existing functions, like the old `advice.el' package, but with much fewer
;; bells and whistles.  It comes in 2 parts:
;;
;; - The first part lets you add/remove functions, similarly to
;;   add/remove-hook, from any "place" (i.e. as accepted by `setf') that
;;   holds a function.
;;   This part provides mainly 2 macros: `add-function' and `remove-function'.
;;
;; - The second part provides `advice-add' and `advice-remove' which are
;;   refined version of the previous macros specially tailored for the case
;;   where the place that we want to modify is a `symbol-function'.
