-;;; Commentary:
-;;
-;; The file-cache package is an attempt to make it easy to locate files
-;; by name, without having to remember exactly where they are located.
-;; This is very handy when working with source trees. You can also add
-;; frequently used files to the cache to create a hotlist effect.
-;; The cache can be used with any interactive command which takes a
-;; filename as an argument.
-;;
-;; It is worth noting that this package works best when most of the files
-;; in the cache have unique names, or (if they have the same name) exist in
-;; only a few directories. The worst case is many files all with
-;; the same name and in different directories, for example a big source tree
-;; with a Makefile in each directory. In such a case, you should probably
-;; use an alternate strategy to find the files.
-;;
-;; 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-filter-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-list': Same as above, but acts on a list
-;; of directories. You can use `load-path', `exec-path' and the like.
-;;
-;; * `file-cache-add-directory-using-find': Uses the `find' command to
-;; add a directory tree to the cache.
-;;
-;; * `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
-;; about extra files in the cache.
-;;
-;; The most convenient way to initialize the cache is with an
-;; `eval-after-load' function, as noted in the ADDING FILES
-;; AUTOMATICALLY section.
-;;
-;; FINDING FILES USING THE CACHE:
-;;
-;; You can use the file-cache with any function that expects a filename as
-;; an argument. For example:
-;;
-;; 1) Invoke a function which expects a filename as an argument:
-;; M-x find-file
-;;
-;; 2) Begin typing a file name.
-;;
-;; 3) Invoke `file-cache-minibuffer-complete' (bound by default to
-;; C-TAB) to complete on the filename using the cache.
-;;
-;; 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.
-;;
-;; 5) You can then edit the minibuffer contents, or press RETURN.
-;;
-;; It is much easier to simply try it than trying to explain it :)
-;;
-;;; ADDING FILES AUTOMATICALLY
-;;
-;; For maximum utility, you should probably define an `eval-after-load'
-;; form which loads your favorite files:
-;;
-;; (eval-after-load
-;; "filecache"
-;; '(progn
-;; (message "Loading file cache...")
-;; (file-cache-add-directory-using-find "~/projects")
-;; (file-cache-add-directory-list load-path)
-;; (file-cache-add-directory "~/")
-;; (file-cache-add-file-list (list "~/foo/bar" "~/baz/bar"))
-;; ))
-;;
-;; If you clear and reload the cache frequently, it is probably easiest
-;; to put your initializations in a function:
-;;
-;; (eval-after-load
-;; "filecache"
-;; '(my-file-cache-initialize))
-;;
-;; (defun my-file-cache-initialize ()
-;; (interactive)
-;; (message "Loading file cache...")
-;; (file-cache-add-directory-using-find "~/projects")
-;; (file-cache-add-directory-list load-path)
-;; (file-cache-add-directory "~/")
-;; (file-cache-add-file-list (list "~/foo/bar" "~/baz/bar"))
-;; ))
-;;
-;; Of course, you can still add files to the cache afterwards, via
-;; 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.
