NAME
     MPI_Comm_group - Accesses the group associated with the given
     communicator

SYNOPSIS
     C:

          #include <mpi.h>

          MPI_Comm comm;
          MPI_Group *group;


     C++:

          #include <mpi.h>

          Group Comm::Get_group() const


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)
