;;; Commentary:
|
|
|
|
;; These routines provide a simple and easy-to-use converter from
|
|
;; Kana-string to Kana-Kanji-mixed-string. This converter (here after
|
|
;; KKC) uses a SKK dictionary to get information how to convert
|
|
;; Kana-string. Since KKC can't be fully automated, we need an
|
|
;; interaction with a user to decide the correct conversion. For
|
|
;; that, we provide KKC major mode.
