specified forms. It is based on a similar version used to initialise
the excision-mask for Whisky code.

\section{Using This Thorn}
Using this thorn is quite easy:
You have to activate it in your parameter file and specify at least the
following:
\begin{verbatim}
hydro_initexcision::hydro_initexcision = "yes"
\end{verbatim}
In addition to that you may want to specify the type of excision zone
you want to have. You can do this by
\begin{verbatim}
hydro_initexcision::hydro_initexcision_type = <TYPE>
\end{verbatim}
where \begin{verbatim}<TYPE>\end{verbatim} is one of the following list:
\begin{itemize}
\item "x-axis"
\item "y-axis"
\item "z-axis"
\item "box"
\item "sphere"
\end{itemize}
\section{Thorn Source Code}
This was initially written by Andrea Nerozzi and later changed
by Frank L\"offler.
\section{Thorn Documentation}
This documentation was largely written by Frank L\"offler.
