+%\subsection{Papers in languages other than English}
+%\label{sec:non-english}
+%
+% The recommmended way to typeset papers in languages other than
+% English is \textsl{babel} package~\cite{Braams05:Babel}.  For
+% example, to typeset a paper in French (with an English abstract, see
+% below), one puts in the preamble
+% \begin{verbatim}
+% \usepackage[utf8]{inputenx}
+% \usepackage[english,frenchb]{babel}
+% \end{verbatim}
+%
+% Such papers often contain several abstracts: for example, in the
+% language the paper is written \emph{and} in English.  Accordingly,
+% \textsl{aomart} allows several abstracts.  Each abstract must be put
+% inside a group with the corresponding language selected using
+% \cs{selectanguage} command, for example
+% \begin{verbatim}
+% {\selectlanguage{french}%
+%   \begin{abstract}
+%     French abstract
+%   \end{abstract}}
+%
+% {\selectlanguage{english}%
+%   \begin{abstract}
+%     English abstract
+%   \end{abstract}}
