+
+;;; 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)
+;;
+
+;; Following people contributed modifications to isearch-ext.el:
+;;   Kenichi Handa <handa@etlken.etl.go.jp>
+;;   YAMAMOTO Mitsuharu <mituharu@is.s.u-tokyo.ac.jp>
