docdir is variable of automake and its by default set to $(datadir)/doc/dune-common.
Therefore there is not need to set it here.

The am_DATA variable was set to EXTRA_DIST which contained
CMakeLists.txt. Therfore CMakeLists.txt was installed.
This patch fixes this by listing files to install in am_DATA
and using EXTRA_DIST only for those files that are otherwise
not distributed. Suprisingly, some files from am_DATA have to
be listed there, too.

When moving the documentation of the parallel index sets from dune-istl
to dune-common, we forgot to adjust the installation directories accordingly.
This patch fixes this situation.

E.g. the files in am are now installed to share/am/dune-module instead of share/am.

VariableSizeCommunicator now appears in doxyen and the parallel
index sets are a subsection of the parallel section.

There entries in doxyerror.log about undocumented function
parameters and parameters that had a wrong name in the documentation.
This patch fixes this.

This patch introduces a new macro DUNE_UNUSED_PARAMETER(parm) for marking
unused parameters that are there for a purpose (e.g. the prescribed interfac
The macro simply performs a cast to void. In addition all unused parameter w
that I found were removed.

Thanks, Oliver!

The new YaspGrid constructors require an array with the number of cells
in each direction. Unfortunately, there is no array constructor that
takes a single element and copies it to all array elements.

This patch adds a simple function Dune::fill_array() to do just that.

With this patch VariableSizeCommunicator now really supports a varying number of data entries
per index during communication.

[parallel,release] Adds a new buffered communicator that does not need to know the data amount per index when receiving.

During communication of data with a parallel DUNE grid the amount of data items
received at an index is not known at the receiving side. With this communicator
it is possible to build such a communication based on index lists at the sending
and receiving side. With this patch only fixed size of data items per index is
supported.

This fixes make dist.

As decided in the doodle for FS#1395, really old MPI versions will be
deprecated in the 2.3 release.

This patch adds an additional check to the MPI tests for autotools and
cmake that makes sure the user has an MPI which is at least compliant
with MPI-2.1. If the user's version is older, a warning is generated.

The test uses version macros instead of the more standard runtime
MPI version query interface to avoid problems when cross-compiling.

With this patch the USE_CMAKE environment variable is queried whether or not CMake
should be used. This can be overwritten in an options file or on the command line
using either the --cmake or --no-cmakr switch.

The check for constexpr was not copied into the distribution.
Unfortunately, the autotools will only warn about a missing macro, but
give valid results otherwise. This patch adds the cxx11_constexpr.m4 to
Makefile.am, so that it is distributed on "make dist".

This fixes a Clang warning.

Make more precise statement to the user if no template specialization
of DenseMatrixAssigner is found. Also use dune_static_assert instead of
static_assert.

This implementation of an IdentityMatrix does not hold any data. It
implements a reduced version of the DenseMatrix interface including a
standard C++ cast operator to a Dune::FieldMatrix. This code illustrates
the new forward capabilities of DenseMatrixAssigner.

The default implementation of DenseMatrixAssigner replaces redundant
code in dense matrix constructors taking a primitive data type.

[DenseMatrix] Introduce DenseMatrixAssigner for initializing dense matrices from arbitrary right hand sides

In order to overcome the deficiencies of istl_assign_to_fmatrix() we
propose to always use a struct DenseMatrixAssigner for initializing a
dense matrix. This class can be specialized by users for any right hand
side to be used in an assignment.  The new mechanism can bei default
implemented using existing implementations of istl_assign_to_fmatrix()
as well.

There was one line of diff missing in that patch. Sorry!

Previously, copying a RemoteIndexListModifier resulted in a double
free of a pointer to a list of global indices. There was no need to
use a pointer to this, though. After this patch we store the list directly
by value. Thus the default copy constructor works but makes a rather cheap copy
of a (most often empty) singly linked list and we get rid off the non-default
destructor.

Update minimal required versions to these mentioned in the documentation.
Quote argument in AC_PREREQ.
(Thanks to Bård Skaflestad for the heads-up)

Configration of dune fails if the manpages are not distributed.

Professional software has man pages.

Properly quote variable GMP_FOUND.
Do not reuse variable GMP_FOUND.

Treating directories with spaces in autotools is a can of worms.
We now check whether this situation is given and issue an error when
building with autotools.

With this patch dunecontrol will work even if the path to the module
contains spaces. Unfortunately, the tests for dune modules will still
not work as I could not figure out how to use quoting in the CPP_FLAGS.

At least Clang 3.2 complains.
