;;; Commentary:

;; SKK is a Japanese input method running on Mule created by Masahiko
;; Sato <masahiko@sato.riec.tohoku.ac.jp>.  Here we provide utilities
;; to handle a dictionary distributed with SKK so that a different
;; input method (e.g. quail-japanese) can utilize the dictionary.

;; The format of SKK dictionary is quite simple.  Each line has the
;; form "KANASTRING /CONV1/CONV2/.../" which means KANASTRING (仮名文
;; 字列) can be converted to one of CONVi.  CONVi is a Kanji (漢字)
;; and Kana (仮名) mixed string.
;;
;; KANASTRING may have a trailing ASCII letter for Okurigana (送り仮名)
;; information.  For instance, the trailing letter `k' means that one
;; of the following Okurigana is allowed: かきくけこ.  So, in that
;; case, the string "KANASTRINGく" can be converted to one of "CONV1く",
;; CONV2く, ...

;;; Code:

;; Name of a file to generate from SKK dictionary.
