;;
;; OVERVIEW
;;
;; org-export-generic is basically a simple translation system that
;; knows how to parse at least most of a .org buffer and then add
;; various formatting prefixes before and after each section type.  It
;; does this by examining a property list stored in org-generic-alist.
;; You can dynamically add propety lists of your own using the
;; org-set-generic-type function:
;;
;;    (org-set-generic-type
;;     "really-basic-text" 
;;     '(:file-suffix  ".txt"
;;       :key-binding  ?R
;;
;;       :title-format "=== %s ===\n"
;;       :body-header-section-numbers t
;;       :body-header-section-number-format "%s) "
;;       :body-section-header-prefix  "\n"
;;       :body-section-header-suffix "\n"
;;       :body-line-format "  %s\n"
;;       :body-line-wrap   75
;;       ))
;;
;; Note: Upper case key-bindings are reserved for your use.  Lower
;; case key bindings may conflict with future export-generic
;; publications.
;;
;; Then run org-export (ctrl-c ctrl-e) and select generic or run
;; org-export-generic.  You'll then be prompted with a list of export
;; types to choose from which will include your new type assigned to
;; the key "r".
;;
;; ----------------------------------------------------------------------
;;
;; TODO (non-ordered)
;;   * handle function references
;;   * handle other types of multi-complex-listy-things to do
;;     ideas:  (t ?- "%s" ?-)
;;   * handle indent specifiers better
;;     ideas:  (4 ?\  "%s")
;;   * need flag to remove indents from body text
;;   * handle links
;;   * handle internationalization strings better
;;   * date/author/etc needs improvment (internationalization too)
;;   * allow specifying of section ordering
;;     ideas:  :ordering  ("header" "toc" "body" "footer")
;;                         ^ matches current hard coded ordering
;;   * err, actually *do* a footer
;;   * deal with usage of org globals
;;   *** should we even consider them, or let the per-section specifiers do it
;;   *** answer: remove; mostly removed now
;;   * deal with interactive support for picking a export specifier label
;;   * char specifiers that need extra length because of formatting
;;     idea: (?- 4)  for 4-longer
;;   * centering specifier
;;     idea: ('center " -- %s -- ")
;;   * remove more of the unneeded export-to-ascii copy code
;;   * tags
;;     *** supported now, but need separate format per tag
;;     *** allow different open/closing prefixes
;;   * properties
;;   * drawers
;;   * oh my
;;   * optmization (many plist extracts should be in (let) vars
;;   * define defcustom spec for the specifier list
