+
+ ;;; Commentary:
+
+ ;; This file provides a generic function to look up a Japanese
+ ;; dictionary of SKK format.
+ ;;
+ ;; SKK is a free Japanese input method running on Mule created by
+ ;; Masahiko Sato <address@hidden>. The Emacs Lisp
+ ;; library kkc.el provides a facility to convert a Japanese kana
+ ;; string to a kanji-kana-mixed string by using SKK's dictionary.
+ ;;
+ ;; The original SKK dictionary SKK-JISYO.L is converted to ja-dic.el
+ ;; by ja-dic-cnv.el. We get entries of the dictionary in four
+ ;; variables (listed below) by loading that file (or byte-compiled
+ ;; version ja-dic.elc).
+
+ ;;; Code:
+
+ ;; The following four variables are set by loading ja-dic.el[c].
