/** \mainpage The p4est parallel adaptive mesh refinement library
 *

 *
 * p4est is a software library for parallel adaptive mesh refinement (AMR).  It
 * represents the mesh as one or more conforming hexahedra that can be
 * individually refined as adaptive octrees, yielding a distributed
 * non-conforming mesh.  Both 2D and 3D are supported.  p4est is intended to be
 * compiled and linked against by numerical simulation codes that require
 * efficient in-core, static or dynamic load balancing and (re-)adaptation of
 * the computational mesh.
 *
 * The p4est provides data structures and routines for all of the following:
 *
 *  * creating a coarse computational mesh;
 *  * adapting the mesh by refining, coarsening, and enforcing 2:1 conditions
 *    between neighbors;
 *  * partitioning a mesh between MPI processes;
 *  * visualizing a mesh;
 *  * communicating ghost layers and data between processes;
 *  * converting the octree format to other static mesh formats;
 *  * etc.
 *
 * More guidance on the usage of p4est can be found in
 * [p4est-howto.pdf](http://p4est.github.io/p4est-howto.pdf),
 * which is distributed with the
 * [source](http://github.com/cburstedde/p4est) under the
 * [doc/](https://github.com/cburstedde/p4est/tree/develop/doc) directory.
 *
 * To build the p4est library from a tar distribution, use the standard
 * procedure of the GNU autotools.  The configure script takes the following
 * options:
 *
 * * `--enable-debug`   lowers the log level for increased verbosity and
 *                    activates the `P4EST_ASSERT` macro for consistency checks.
 * * `--enable-mpi`     pulls in the mpi.h include file and activates the MPI
 *                    compiler wrappers.  If this option is not given, wrappers
 *                    for MPI routines are used instead and the code is compiled
 *                    in serial only.
 * * `--disable-mpiio`  may be used to avoid using `MPI_File` based calls.
 *
 * A typical development configure line looks as follows:
 * > `relative/path/to/configure CFLAGS="-Wall -O0 -g" --enable-mpi --enable-debug`
 * A typical production configure line looks as follows:
 * > `relative/path/to/configure CFLAGS="-Wall -O2" --enable-mpi`
