;; * `file-cache-add-directory-using-locate': Uses the `locate' command to
;; add files matching a pattern to the cache.
;;
+;; * `file-cache-add-directory-recursively': Uses the find-lisp package to
+;; add all files matching a pattern to the cache.
+;;
;; Use the function `file-cache-clear-cache' to remove all items from the
;; cache. There are a number of `file-cache-delete' functions provided
;; as well, but in general it is probably better to not worry too much
