;;; Commentary:

;; This program is extension of isearch.el to support multi-lingal
;; incremental search with front-end input method.
;; If you want to use this program, simply put C-\ or C-o or C-[ when
;; doing incremental search, and you can input search words with
;; inputting method.
;; For backward compatibility with mule-1.x, you can also use C-k, but
;; isearch-edit-string may be more suitable for this use.  If you
;; think so, put the following code in your .emacs.
;;   (define-key isearch-mode-map "\C-k" 'isearch-edit-string)

;; #### This is far from working in XEmacs.
