;;; Commentary:
;;
;; This library implements a Texinfo back-end for Org generic
;; exporter.
;;
;; To test it, run
;;
;;   M-: (org-export-to-buffer 'texinfo "*Test Texinfo*") RET
;;
;; in an Org mode buffer then switch to the buffer to see the Texinfo
;; export.  See ox.el for more details on how this exporter works.
;;

;; It introduces nine new buffer keywords: "TEXINFO_CLASS",
;; "TEXINFO_FILENAME", "TEXINFO_HEADER", "TEXINFO_POST_HEADER",
;; "TEXINFO_DIR_CATEGORY", "TEXINFO_DIR_TITLE", "TEXINFO_DIR_DESC"
;; "SUBTITLE" and "SUBAUTHOR".

;;
;; It introduces 1 new headline property keywords:
;; "TEXINFO_MENU_TITLE" for optional menu titles.
;;
;; To include inline code snippets (for example for generating @kbd{}
;; and @key{} commands), the following export-snippet keys are
;; accepted:
;;
;;     texinfo
;;     info
;;
;; You can add them for export snippets via any of the below:
;;
;;    (add-to-list 'org-export-snippet-translation-alist
;;                 '("info" . "texinfo"))

The sectioning structure

The sectioning structure of the class is given by the elements
following the header string.  For each sectioning level, a number
of strings is specified.  A %s formatter is mandatory in each
section string and will be replaced by the title of the section.

Instead of a list of sectioning commands, you can also specify
a function name.  That function will be called with two
parameters, the \(reduced) level of the headline, and a predicate
non-nil when the headline should be numbered.  It must return
a format string in which the section title will be added."
