Hi Jacob,

#+LATEX_HEADER: does work on export (when else would it work?)

Agreed. If I said otherwise it was a mistake.

2) From Aaron Ecay, put your header in a #+BEGIN_SRC latex section, and
then run a bit of lisp to export that section, and then include the
exported file in a #+LATEX_HEADER: \include{preamble}. This is the
approach I use.

| #+end_src

This looks handy. Thanks!

My elisp ability is minimal, but if someone can point me towards where I would look to try to create an export analogue to org-format-latex-header, I would at least take a look and try to come up with a patch.

Thanks,

Jake
