+% \begin{declcs}{AtBeginShipoutUpperLeft} \M{background material}
+% \end{declcs}
+% This is a macro that puts material in the background of
+% box \cs{AtBeginShipoutbox}.
+% The \meta{background material} is set in an \cs{hbox}, the
+% reference point is the upper left corner of the output page.
+% In case of \pdfTeX\ in PDF mode, the settings of
+% \cs{pdfhorigin} and \cs{pdfvorigin} are respected.
+%
+% For \LaTeX\ users the \meta{background material} is set
+% inside a \texttt{picture} environment:
+% \begin{quote}
+% |\begin{picture}(0,0)|\\
+% \mbox{}\quad |\setlength{\unitlength}{1pt}%|\\
+% \mbox{}\quad \meta{background material}\\
+% |\end{picture}|
+% \end{quote}
+%
+% \subsection{Example}
+%
+% In this example we put a circle in the background in the middle
+% of the paper.
