+;;; Commentary:
+
+;; This library is 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'
+;; M-x `org-export-region-as-latex'
+;; M-x `org-replace-region-by-latex'
+
+;;; History:
+;;
+;; I started this piece of code in may 2007. Special thanks to Carsten
+;; Dominik for helping me on this.
