Attached are:

	 - ox-deck.el
	 - ox-s5.el

Which, respectively, provide deck.js and s5 backends for the new
exporter. I would be happy for these to be included in contrib. Note
that I have already signed the FSF assignment documents, so they can
be safely included in the core if so desired.

;; the gitub repository at https://github.com/imakewebthings/deck.js.
;;
;; Add the path to the extracted code to the variable

;; org-export-deck group, most of which can be overrriden with buffer
;; local customization (starting with DECK_.)

;; See ox.el and ox-html.el for more details on how this exporter
;; works (it is derived from ox-html.)

;; (Note that the default s5 version is set for using the alpha, 1.2a2.
;; Copy the ui dir to somewhere reachable from your published presentation
;; The default (`org-s5-ui-url') is set to "ui" (e.g., in the
;; same directory as the html file).

;; Usage
;; -----
;; Follow the general instructions at the above website. To generate
;; incremental builds, you can set the HTML_CONTAINER_CLASS on an
;; object to "incremental" to make it build. If you want an outline to
;; build, set the` INCREMENTAL property on the parent headline.

;; To test it, run:
;;
;;   M-x org-s5-export-as-html
;;
;; in an Org mode buffer.  See ox.el and ox-html.el for more details
;; on how this exporter works.
