+% \subsection{The \pkg{underscore} first aid}
+%
+% The \pkg{underscore} package makes the underscore active. This means that the
+% underscore can not be used in label and references unless the package option \texttt{strings} is used
+% (which patches a selection of problematic commands like \cs{label} and \cs{ref})
+% or \pkg{babel} is used which redefines\footnote{unless the recommended option \texttt{safe=none} is used}
+% a selection of problematic commands like \cs{@testdef} or \cs{@newl@bel}.
+%
+% With the new property commands the work-around do not work. We therefore make the
+% underscore protected and use \cs{ifincsname} to allow its use in csnames.
