-\minisec{Faster module search}
-If the environment variable \texttt{DUNE\_CONTROL\_PATH} is not set, \dunecontrol 
-recursively searches for \dune modules below the working directory. Depending on
-your installation, this search may take quite a bit of time.  It can be
-avoided by including the paths to the \texttt{dune.module} files of all modules in 
-\texttt{DUNE\_CONTROL\_PATH}.
-
-This list of paths can actually be created on the fly by a command.
-Let us assume all \dune modules are in one directory, which is the working directory 
-for \dunecontrol, too. By adding the line
-\begin{lstlisting}[language=make,showstringspaces=false]
-DUNE_CONTROL_PATH="`ls */dune.module | tr '\n' ':'`"
-\end{lstlisting}
-to your opts file, no search will be performed.  Instead, only the faster, non-recursive 
-\texttt{ls} command is called.
