[Orgmode] Title page for book latex export

[Jordi Inglada]

Hi all,

I would like to export to LaTeX using "#+LaTeX_CLASS: book" and use a
title page that I have built using the LaTeX titlepage environment. I
don't know where to put the titlepage environment and how to
deactivate the title page generation by the LaTeX export.

Thank you for your help.

Jordi
