Hi Jerry,

I do this using org-babel.  I love being able to write my article *and* my beamer presentation in the same file.  Using the literate programming facility of org-babel, I'm able to write them each in pieces, then assemble them at the end for tangling and export.  This means I have to write real LaTeX and beamer code, rather than having the LaTeX export facility of org-mode do its work, but org-mode makes this easy with Ctrl-C ', which opens up the source block in a buffer where auctex and reftex are active.

It looks something like this:

#+srcname: latex-preamble
#+begin_src latex :exports none
\documentclass{article}
\author{A. N. Author}
\title{Article Title}
\newcommand{\attr}[1]{\textbf{#1}}

\begin{document}

\maketitle
#+end_src

#+srcname: beamer-preamble
#+begin_src latex :exports none
\documentclass{beamer}
... (lots of stuff here)
\begin{document}

\maketitle

#+end_src

#+srcname: latex-document
#+begin_src latex :tangle adz_print.tex :exports none
  % <<latex-preamble>>
  % <<latex-introduction>
...
  \end{document}
#+end_src

#+srcname: beamer-document
#+begin_src latex :tangle adz_beamer.tex :exports none
  % <<beamer-preamble>>
  % <<beamer-introduction>>
...
  \end{document}
#+end_src

Calling org-babel-tangle gives me adz_print.tex for my article and adz_beamer.tex for my beamer presentation.

There are probably other ways to achieve this (org-mode, you know) that might be simpler.

The text I write outside the source blocks tracks what I hope to achieve, decisions I've made, etc. and uses the export facilities of org-mode to create a user manual for my employees.  Right now I'm targeting html for the user manual, but LaTeX export would also work.

HTH,
Tom

Hi,

A question about exporting:

Is it possible to export two different subtrees in the same file to a different class?  There are cases where it would be nice to be able to generate a document (say an article) from a single subtree in a file, and have other subtrees that contain short presentations that could be exported quickly to beamer, for example.  Currently, the exporter seems to find the first #+LaTeX_CLASS in the file and use that for the entire file export, as well as exporting any subtree in the file, even if you define a separate LaTeX_CLASS under a specific subtree.  I have looked into using export OPTIONS in subtrees for this, but have not hit on the right combination.  Is this possible?

Thanks,
Jerry
