-/** @example HelloMoabPar.cpp \n
- * \brief Read mesh into MOAB in parallel \n
- * This example shows the simplest way of telling MOAB to read in parallel.
- *
- *    -#  Initialize MPI and get the rank and number of processors \n
- *    -#  Process arguments (file name and options for parallel read) \n
- *    -#  Initialize MOAB \n
- *    -#  Load a partitioned file in parallel; \n
- *    -#  retrieve shared entities on each processor \n
- *    -#  Filter owned entities among shared ones on each processor \n
- *    -#  Exchange ghost layers, and repeat the reports \n
- *
- * <b>To compile</b>: \n
- *    make HelloMoabPar MOAB_DIR=<installdir>  \n
- * <b>To run</b>: mpiexec -np 4 HelloMoabPar \n
- *  (depending on your configuration, LD_LIBRARY_PATH may need to contain <hdf5>/lib folder)
- *
