;;; Commentary:
|
|
;;
|
|
;; This library implements a LaTeX exporter for org-mode.
|
|
;;
|
|
;; Put this file into your load-path and the following into your ~/.emacs:
|
|
;; (require 'org-export-latex)
|
|
;;
|
|
;; The interactive functions are similar to those of the HTML exporter:
|
|
;;
|
|
;; M-x `org-export-as-latex'
|
|
;; M-x `org-export-as-latex-batch'
|
|
;; M-x `org-export-as-latex-to-buffer'
