;;; Commentary:
;; SKK is a free Japanese input method running on Mule created by
;; Masahiko Sato <masahiko@sato.riec.tohoku.ac.jp>. A dictionary of
;; SKK can be converted by `skkdic-convert' (skkdic-conv.el) to a file
;; "skkdic.el" in which the dictionary entries are defined in the
;; format which can be handled by the following functions.
;; Masahiko Sato <masahiko@sato.riec.tohoku.ac.jp>. The Emacs Lisp
;; library kkc.el provides a facility to convert a Japanese kana
;; string to a kanji-kana-mixed string by using a SKK dictionary.
;;
;; This file provides a generic function to look up a SKK dictionary.
;;
;; The original SKK dictionary SKK-JISYO.L is converted to skkdic.el.
;; We get entries of the dictionary in four variables (listed below)
;; by loadig this file (or byte-compiled version skkdic.elc).
;;; Code:
;; The following four variables are set by loading skkdic.el[c].
