mention CAD support and second order boundary segments for Gmsh :-)

Arguably the most important file format currently supported by \Dune is
the \lstinline!gmsh! format. \lstinline!Gmsh!\footnote{\url{http://geuz.org/gmsh/}}
is an open-source grid generator. It creates simplicial grids in 2d and 3d
and stores them in files ending in \lstinline!.msh!. To read such a
file into a FooGrid, include \lstinline!dune/grid/io/file/gmshreader.hh!
and stores them in files ending in \lstinline!.msh!. \lstinline!Gmsh!
can be compiled with \lstinline!OpenCascade!, an open-source CAD
kernel. Via \lstinline!gmsh!
CAD geometries, e.~g.~from IGES or STEP files, can be meshed and subsequently be used in
\Dune. Moreover, the reader supports second order
boundary segments thus providing a rudimentary support for curved boundaries.
To read such a file into a FooGrid, include \lstinline!dune/grid/io/file/gmshreader.hh!
and write
\begin{lstlisting}
FooGrid* grid = GmshReader<GridType>::read(filename);
