[Orgmode] Setting up LATEX_HEADER properly.

[gerald . jean]

Hello,

I am new to org-mode, not to Emacs and LaTeX though.  I am trying to export
an org document to LaTeX.  It does export but not with the options I want.
For example, trying to add just one package I have the following at the end
of my org file, I tried to put it at the begining also but it didn't work
neither?  Any way I tried to include packages didn't work, I also tried
with "#+SETUPFILE: /home/jeg002/org/2010/setupLaTeX.org", no luck?
