  Functions defined in this file are

  (canna-key-proc key)
 		key: single STRING
 		RETURNS:
			 Length of converted string if no error occurs.
			 Error string if error occurs.
 		DESCRIPTION:
			 Convert a key input to a set of strings.  The
			 strings contain both well-formed string and a
			 intermediate result to show the translation
			 information to a user.  converted strings are
			 stored in specific variables.

  (canna-initialize)
  		RETURNS:
			List of the following things:
			- list of keys to toggle Japanese-mode
			- error message
			- list of warning messages
		DESCRIPTION:
			Initialize ``canna'', which is a kana-to-kanji
			converter for GNU Emacs.  The first arg
			specifies if inserting space character between
			BUNSETSU when candidates are displayed.  The
			second arg specifies server.  The third arg
			specifies a file which will be used as a
			customization description.  If nil is
			specified for each arg, the default value will
			be used.

  (canna-finalize)
		RETURNS:
			list of warning messages
		DESCRIPTION:
			finalize ``canna'', which is a kana-to-kanji
			converter for GNU Emacs.  This cause to write
			miscellaneous informations to kana-to-kanji
			dictionary.

  (canna-touroku-string string)
		string:
			String to register to a dictionary.
		RETURNS:
			The same thing returns as canna-key-proc does.
		DESCRIPTION:
			Register Kanji words into kana-to-kanji
			conversion dictionary.

  (canna-set-width width)
		width:
			Column width of the place where the candidates
			of kana-to-kanji conversion will be shown.
		RETURNS:
			nil
		DESCRIPTION:
			Set status-line width information, which is
			used to display kanji candidates.

  (canna-change-mode num)
		num:
			The mode number of Canna.
		RETURNS:
			The same thing returns as canna-key-proc does.
		DESCRIPTION:
			Change Japanese pre-edit mode.

  (canna-store-yomi yomi roma)
		yomi:
			``Yomi'' to be stored.
		roma:
			``Romaji'' which corresponds to the ``Yomi''.
		RETURNS:
			The same thing returns as canna-key-proc does.
		DESCRIPTION:
			Store yomi characters as a YOMI of
			kana-to-kanji conversion.

  (canna-do-function num ch)
		num:
			A function number to be called.
		ch:
			A character will be specified in order to feed
			the character to the function if the function
			needs a input character.
		RETURNS:
			The same thing returns as canna-key-proc does.
		DESCRIPTION:
			Do specified function at current mode.

  (canna-parse string)
		string:
			To be parsed.
		RETURNS:
			List of warning messages.
		DESCRIPTION:
			Parse customize string.

  (canna-query-mode)
		RETURNS:
			A string which indicate the current mode.
		DESCRIPTION:
			Get current mode string.

  Functions below are used for KKCP compatible library.  These
  functions provides a base kana-to-kanji conversion system for EGG.
  These functions may be used when users want to change the engine
  from Wnn to Canna without changing user interface of Japanese input.

  (canna-henkan-begin)
  (canna-henkan-next)
  (canna-bunsetu-henkou)
  (canna-henkan-kakutei)
  (canna-henkan-end)
  (canna-henkan-quit)
