# putting two things in background with background & TikZ

I am trying to put two lines of background text over each page. I currently use background with TikZ to put one line of text at the bottom, but I additionally need to put "Confidental" accross every page.

\documentclass{minimal}
\usepackage[a5paper]{geometry}
\usepackage{lipsum}
\usepackage{background}
\backgroundsetup{
contents={This document contains things which not everybody is supposed to read.},
scale=1.0,
placement=bottom,
angle=0,
color=red!50,
pages=all
}
\begin{document}
\lipsum{10}
\end{document}

How can I add more material to background? In fact I am not sure what is supposed to go to contents, is it rendered via TikZ's \draw or something similar.

I need to be able to set things up in the preamble, as the rest of the document is generated via Sphinx and I have no chance adding things into document body (without hacks).

Something like this? (All I did is paste the example from the pgfmanual in section 17.13.2 in.) NOTE: An arguably much safer answer can be found below. When I wrote the following answer, I ignored the fact that backgrounds uses TikZ, and thus did not realize that I nest tikzpictures. Sorry for that!)

\documentclass{minimal}
\usepackage[a5paper]{geometry}
\usepackage{lipsum}
\usepackage{background}
\usepackage{tikz}
\backgroundsetup{
contents={This document contains things which not everybody is supposed to read.
\begin{tikzpicture}[remember picture,overlay] \node [rotate=60,scale=10,text opacity=0.2]
at (current page.center) {Confidential};
\end{tikzpicture}},
scale=1.0,
placement=bottom,
angle=0,
color=red!50,
pages=all
}
\begin{document}
\lipsum{10}
\end{document}

UPDATE: Actually I think that my above original answer may be somewhat dangerous. Please consider switching to

\documentclass{minimal}
\usepackage[a5paper]{geometry}
\usepackage{lipsum}
%\usepackage{background}
\usepackage{tikz}
\usepackage{eso-pic}
