;;; Commentary:
|
||
;;
|
||
;; This library implements a Man back-end for Org generic exporter.
|
||
;;
|
||
;; To test it, run
|
||
;;
|
||
;; M-: (org-export-to-buffer 'e-man "*Test e-Man*") RET
|
||
;;
|
||
;; in an org-mode buffer then switch to the buffer to see the Man
|
||
;; export. See contrib/lisp/org-export.el for more details on how
|
||
;; this exporter works.
|
||
;;
|
||
;; It introduces one new buffer keywords:
|
||
;; "MAN_CLASS_OPTIONS".
