+% \subsection{Adding symbols for breaks}\label{sec:breaks}
+% \changes{v1.1}{2014/07/02}{New section about breaks (see \ref{sec:breaks})}
+% As seen in the examples above you can use pipes, i.e. +|+ or +||+, to mark breaks.
+% In \cs{metrics} the markers must appear in \meta{symbols} and \meta{syllables}.
+% \begin{example}
+%   \begin{verbatim}
+% \metrics{_    u  u  _   _  _  | _    _  u  u   _  ||}
+%         {flos ve-te-ris vi-ni | meis na-ri-bus ob ||}
+%   \end{verbatim}
+% \metrics{_    u  u  _   _  _  | _    _  u  u   _  ||}
+%         {flos ve-te-ris vi-ni | meis na-ri-bus ob ||}
+% \end{example}
+% If you want the breaks to be shown in the symbol line only you can use the
+% shorter break which is represented by an apostrophe, i.e. +'+.
+% This mark must be used in \meta{symbols} only and is kind of special:
+% \begin{itemize}
+%    \item It \emph{can't} be highlighted and thus doesn't count for the numbers used
+%       for highlights,
+%    \item it is ignored at the beginning and the end of \meta{symbols},
+%    \item in \cs{metricsymbols} it is treated like the pipe, and
+%    \item \TeX\ needs at least one additional run to get the right positions.
+% \end{itemize}
+% \begin{example}
+%   \begin{verbatim}
+% \metrics{_  u  u ' _  u   u ' _  _ ' _  _   |  _  u   u  |  _ _   ||}
