! !MODULE: m_mpif - a portable interface to the MPI "mpif.h" COMMONs.
!
! !DESCRIPTION:
!
!   The purpose of \verb"m_mpif" module is to provide a portable
!   interface of \verb"mpif.h" with different MPI implementation.
!   By combining module \verb"m_mpif" and \verb"m_mpif90", it may be
!   possible to build a Fortran 90 MPI binding module graduately.
!
!   Although it is possible to use \verb'include "mpif.h"' directly
!   in individual modules, it has several problems:
!   \begin{itemize}
!   \item It may conflict with either the source code of a {\sl fixed}
!	format or the code of a {\sl free} format;
!   \item It does not provide the protection and the safety of using
!	these variables as what a \verb"MODULE" would provide.
!   \end{itemize}
!
!   More information may be found in the module \verb"m_mpif90".
