this is my flavor. The version above is superior in that it filters dups, but I don't see that
as a serious problem for small cases.
 
(setq load-path
  (append
    ;; overide distributed elisp with local modifications by
    ;; inserting a "local" directory at the beginning of the
    ;; load list
    (cons localized-source-dir load-path)

    ;; add the extras to the end of the list.
    (list extras-source-dir)
    ))

in this version anything you want to override emacs goes in localized-source-dir, while anything that is an add-on
can simply go in the list at the end.
