                   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.

                  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.

                  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:
                  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-next)
  (canna-bunsetu-henkou)
  (canna-henkan-kakutei)
