;;; Commentary:

;; Loading this package defines three ways of entering the non-ASCII
;; printable characters with codes above 127: the prefix C-x 8, or the
;; Alt key, or a dead accent key.  For example, you can enter uppercase
;; A-umlaut as `C-x 8 " A' or `Alt-" A' (if you have an Alt key) or
;; `umlaut A' (if you have an umlaut/diaeresis key).

;; C-x 8 is set up to autoload this package,
;; but Alt keys and dead accent keys are only defined
;; once you have loaded the package.  It is nontrivial
;; to make all of the Alt keys autoload, and it is not clear
;; that the dead accent keys SHOULD autoload this package.

;;; Code:

;;; Provide some binding for startup:
;;;###autoload (or key-translation-map (setq key-translation-map (make-sparse-keymap)))
;;;###autoload (define-key key-translation-map "\C-x8" 'iso-transl-ctl-x-8-map)
;;;###autoload (autoload 'iso-transl-ctl-x-8-map "iso-transl" "Keymap for C-x 8 prefix." t 'keymap)
