[O] exporter for latex g-brief - extending \begin{document}

[LanX]

Hi

Im using a latex class called g-brief to create formal german letters (see e.g. http://vimpy.org/wp/archives/47) and I'm trying to add an exporter to org-mode.

my problem is that I need to enclose the text within

\begin{document}

\begin{g-brief}

... here comes text

\end{g-brief}

\end{document}

so any customization possibilities to nest the document within begin/end{g-brief} (before I try patching the org-mode.el)

Does it help to upgrade, my org-version is 7.7

Thanks

 Rolf
