  31 ;; This library implements a LaTeX exporter for org-mode.
  32 ;;
  33 ;; Put this file into your load-path and the following into your ~/.emacs:
  34 ;;   (require 'org-export-latex)
  35 ;;
  36 ;; The interactive functions are similar to those of the HTML exporter:
  37 ;;
  38 ;; M-x `org-export-as-latex'
  39 ;; M-x `org-export-as-pdf'
  40 ;; M-x `org-export-as-pdf-and-open'
  41 ;; M-x `org-export-as-latex-batch'
