;;; Commentary:
;; This file implements the support for Sebastian Rose's JavaScript
;; org-info.js to display an org-mode file exported to HTML in an
;; Info-like way, or using folding similar to the outline structure
;; org org-mode itself.
;; Documentation for using this module is in the Org manual. The script
;; itself is documented by Sebastian Rose in a file distributed with
;; the script. FIXME: Accurate pointers!
;; Org-mode loads this module by default - if this is not what you want,
;; configure the variable `org-modules'.
