;;; Example (In English). 
;;;
;;; The Chinese character is an ideogram character. Therefore when you
;;; see a character, you know what it means, but you do not know
;;; how to pronounce it. You know the mean but you can not read
;;; (sound) it. It is like Arabic number. For example: `1'. This is
;;; pronounced: English `one', Deutsch `eins', Japanese `ichi/hii',
;;; Korean `iru/hana' and so on.
;;;
;;; So, Some students need how to read these charactors. This program
;;; helps to input such pronounciation.
;;;
;;; Example 1. (English). 
;;; 
;;;    1/2 -> 1/2(half)
;;;    1/2 -> 1/2(one over two)
;;; 
;;; Example 2. (Japanese). (The code is EUC.)
;;;	
;;;   姉妹 -> 姉妹(しまい) / 姉妹(simai) 
;;;
;;; Example 3. You can set up with addruby-*-text as follows. This is
;;; easy way to add TeX ruby command.
;;;
;;;  (setq addruby-prefix-from-text "\\ruby{")
;;;  (setq addruby-postfix-from-text "}")
;;;  (setq addruby-prefix-to-text "{")
;;;  (setq addruby-postfix-to-text "}")
;;; 
;;;   姉妹 -> \ruby{姉妹}{しまい}
