;; This library implements a HTML back-end for Org generic exporter.

;; To test it, run
;;
;;   M-: (org-export-to-buffer 'e-html "*Test e-HTML*") RET
;;
;; in an org-mode buffer then switch to the buffer to see the HTML
;; export.  See contrib/lisp/org-export.el for more details on how
;; this exporter works.

KEYWORD and OPTION have precedence over DEFAULT.

All these properties should be back-end agnostic.  For back-end
specific properties, define a similar variable named
