Aloha Robert,

I've added :exports none to the example, which came from a document
about how to export LaTeX documents from Org-mode.  Thanks for pointing
out that it could be used in a way that yields unexpected results.

In my usual setup I put this kind of configuration in a heading of its
own that is protected by a :noexport: tag.  This works for me because I
often have notes about why things are in there and what I think they
might be doing.

All the best,
Tom
