;;; Synched up with: Not in FSF

;;; Commentary:

;; In FSF all of the custom loads are in a single `cus-load' file.
;; However, we have them distributed across directories, with optional
;; incremental loading.  Here we simply collect the whole set.


;;; Code:

(require 'custom)

(defun custom-add-loads (symbol list)
  "Update the custom-loads list of a symbol.
This works by adding the elements from LIST to the SYMBOL's
`custom-loads' property, avoiding duplicates.  Also, SYMBOL is
added to `custom-group-hash-table'."
  (let ((loads (get symbol 'custom-loads)))
    (dolist (el list)
      (unless (member el loads)
	(setq loads (nconc loads (list el)))))
    (put symbol 'custom-loads loads)
    (puthash symbol t custom-group-hash-table)))

(message "Loading customization dependencies...")

;; Garbage-collection seems to be very intensive here, and it slows
;; things down.  Nuke it.
(let ((gc-cons-threshold most-positive-fixnum))
  (mapc (lambda (dir)
	  (load (expand-file-name "custom-load" dir) t t))
	load-path))
