This document presents the \texttt{sintefmemo} class.
A subclass of \texttt{sintefdoc}, it reproduces the behaviour of
the SINTEF memo template.
Title, author and date are set with \LaTeX's usual commands
\verb|\title|, \verb|\author| and \verb|\date|.
The recipients are specified in the preamble with the \verb|\recipient|
command.
The recipient is specified in the mandatory argument, whereas the optional
argument can include the keywords \verb|attention|, \verb|comments|,
\verb|information|, \verb|agreed|, or a combination thereof separated by
commas, \emph{without intervening spaces}. For example:
\begin{verbatim}
\recipient[attention,agreed]{\LaTeX\ users}
\end{verbatim}
Finally, the project is set with the \verb|\project| command, and
to typeset the first page you need to insert the \verb|\frontmatter|
command just after \verb|\begin{document}|.
