;;; Commentary:
;;
;; ADDING FILES TO THE CACHE:
;;
;; Use the following functions to add items to the file cache:
-;;
+;;
;; * `file-cache-add-file': Adds a single file to the cache
;;
;; * `file-cache-add-file-list': Adds a list of files to the cache
;;
;; The following functions use the regular expressions in
;; `file-cache-delete-regexps' to eliminate unwanted files:
-;;
+;;
;; * `file-cache-add-directory': Adds the files in a directory to the
;; cache. You can also specify a regular expression to match the files
;; which should be added.
;; * `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
;;
;; 4) When you have found a unique completion, the minibuffer contents
;; will change to the full name of that file.
-;;
+;;
;; If there are a number of directories which contain the completion,
;; invoking `file-cache-minibuffer-complete' repeatedly will cycle through
;; them.
;; For maximum utility, you should probably define an `eval-after-load'
;; form which loads your favorite files:
;;
-;; (eval-after-load
+;; (eval-after-load
;; "filecache"
;; '(progn
;; (message "Loading file cache...")
;; If you clear and reload the cache frequently, it is probably easiest
;; to put your initializations in a function:
;;
-;; (eval-after-load
+;; (eval-after-load
;; "filecache"
;; '(my-file-cache-initialize))
-;;
+;;
;; (defun my-file-cache-initialize ()
;; (interactive)
;; (message "Loading file cache...")
;; Lisp functions.
;;
;; RELATED WORK:
-;;
+;;
;; This package is a distant relative of Noah Friedman's fff utilities.
;; Our goal is pretty similar, but the implementation strategies are
;; different.
