|

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