;;; Commentary:
;; This file generates the custom-load files, loaded by cus-load.el.
-;; The only entry point is `Custom-make-dependencies'.
+;; Entry points are `Custom-make-dependencies' and
+;; `Custom-make-one-dependency'.
;; It works by scanning all the `.el' files in a directory, and
;; evaluates any `defcustom', `defgroup', or `defface' expression that
;; understand, but is in fact very easy to break. Be sure to read and
;; understand the commentary above!
