;;; 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:
|
||

|

|
||
;; '("info" . "texinfo"))
