Hi Nick,
Thanks for the patch, sadly I rely on labels in my other latex exports.
For now I'm just using the following little elisp function.
--8<---------------cut here---------------start------------->8---
(defun schulte/clean-beamer ()
"remove the \label{sec} headers from latex Beamer documents
that have been exported by org."
(interactive)
(save-excursion
(goto-char (point-min))
(while (re-search-forward "^\\\\label{" nil t)
(move-beginning-of-line nil)
(delete-region (point) (save-excursion (forward-line 1) (point))))))
--8<---------------cut here---------------end--------------->8---
Thanks -- Eric
