Hello,

I am trying to use new beamer exporter. I have few questions.

o) When trying to export emacs batch mode, it is asking for "Output file:"
(export script and setup file for batch process are attached)

#!/bin/sh
# batch export

emacs -q --batch -l setup.el \
    -f org-e-beamer-export-to-latex org-beamer-template.org

pdflatex -interaction nonstopmode org-beamer-template.tex

# export.sh ends here

--8<---------------cut here---------------start------------->8---
okhotsk19:~/git/org-beamer-template$ ./export.sh
Loading /home/yagnesh/.emacs.d/el-get/org-mode/lisp/org-loaddefs.el (source)...
Output file:
--8<---------------cut here---------------end--------------->8---

By grepping sources, I get this.
grep -nH -e "Output file:" *.el
org-export.el:2759:		 "Output file: " pub-dir nil nil nil

couldn't figure out why it is failing.

o) I used to fold headers for convenience by giving an ARCHIVE tag. its not
working in the new exporter.

o) how to make two column frame. (see attached example, in old exporter)
