I=E2=80=99ve been experimenting with using a single org file to generate =
an article when exported to LaTeX (or HTML) and a Beamer presentation =
when exported to Beamer, without requiring any edits to the org file =
itself.=20

For this to be really useful, the exporter has to be able to do =
different things depending on which output format you=E2=80=99ve asked =
for.=20

1) At a minimum, you need to be able to have text included in the =
article that is not included in the Beamer presentation and vice versa, =
so that you can have, say, a paragraph in the article vs. an itemized =
list in the Beamer presentation. This can be taken care of relatively =
easily using one of several conditional-compilation packages available =
for LaTeX. If people are interested, I=E2=80=99ve uploaded a simple =
example to https://faculty.haas.berkeley.edu/stanton/orgLatexBeamer/ =
<https://faculty.haas.berkeley.edu/stanton/orgLatexBeamer/>

2) However, some things are not so easy. For example, suppose I=E2=80=99m =
using the listings package to include some code in my document, e.g.,

#+begin_src python
  print(=E2=80=9CHello, world=E2=80=9D)
#+end_src

This works fine as long as I=E2=80=99m OK with the default output =
format. But suppose this listing is too long for my slide so I want to =
make the text smaller than normal. I can do that quite easily for both =
article and presentation output by putting a line like

#+attr_latex: :options basicstyle=3D\tiny

immediately before the source block. But suppose I only want to do this =
in the Beamer output and not in the LaTeX article output? I=E2=80=99ve =
tried=20

#+attr_beamer: :options basicstyle=3D\tiny

but this doesn=E2=80=99t seem to work. And even if it did, what if I =
wanted the change in font size to occur only when I=E2=80=99m exporting =
to LaTeX but not Beamer? How can I do conditional things like this at =
the org-file level based on whether I=E2=80=99m exporting to LaTeX or =
Beamer?

Thanks for any suggestions.

Richard Stanton
