\begin{abstract}
Thorn \ThisThorn\ provides the following utility programs:
%
\begin{itemize}
  \item {\tt hdf5\_double\_to\_single}\\
    Copies the entire contents of an input HDF5 file to an output HDF5 file,
    converting all double precision datasets to single precision.
  \item {\tt hdf5\_merge}\\
    Merges a list of HDF5 input files into a single HDF5 output file.
    This can be used to concatenate HDF5 output data created as one file per
    timestep.
  \item {\tt hdf5\_extract}\\
    Extracts a given list of named objects (groups or datasets) from an HDF5
    input file and writes them into a new HDF5 output file.
    This is the reverse operation to what {\tt hdf5\_merge.c} does. Useful eg.
    for extracting individual timesteps from a time series HDF5 datafile.
\end{itemize}
%
All utility programs are located in the {\tt src/util/} subdirectory of thorn
\ThisThorn. To build the utilities just do a

\begin{verbatim}
  make <configuration>-utils
\end{verbatim}

in the Cactus toplevel directory. The executables will then be placed in the
{\tt exe/<configuration>/} subdirectory.

All utility programs are self-explaining -- just call them without arguments
to get a short usage info.
If any of these utility programs is called without arguments it will print
a usage message.
