;;; Commentary:
|
||
;;
|
||
;; This library implements a Groff Memorandum Macro back-end for Org
|
||
;; generic exporter.
|
||
;;
|
||
;; To test it, run
|
||
;;
|
||
;; M-: (org-export-to-buffer 'groff "*Test Groff*") RET
|
||
;;
|
||
;; in an org-mode buffer then switch to the buffer to see the Groff
|
||
;; export. See ox.el for more details on how this exporter works.
|
||
;;
|
||
;; It introduces two new buffer keywords: "GROFF_CLASS" and
|
||
;; "GROFF_CLASS_OPTIONS".
