-# C++
-# ===========================================================================
-#      http://www.gnu.org/software/autoconf-archive/ax_prog_cxx_mpi.html
-# ===========================================================================
-#
-# SYNOPSIS
-#
-#   AX_PROG_CXX_MPI([MPI-WANTED-TEST[, ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]]])
-#
-# DESCRIPTION
-#
-#   This macro tries to find out how to compile C++ programs that use MPI
-#   (Message Passing Interface), a standard API for parallel process
-#   communication (see http://www-unix.mcs.anl.gov/mpi/).  The macro has to
-#   be used instead of the standard macro AC_PROG_CXX and will replace the
-#   standard variable CXX with the found compiler.
-#
-#   MPI-WANTED-TEST is used to test whether MPI is actually wanted by the
-#   user. If MPI-WANTED_TEST is omitted or if it succeeds, the macro will
-#   try to find out how to use MPI, if it fails, the macro will call
-#   AC_PROG_CC to find a standard C compiler instead.
-#
-#   When MPI is found, ACTION-IF-FOUND will be executed, if MPI is not found
-#   (or MPI-WANTED-TEST fails) ACTION-IF-NOT-FOUND is executed. If
-#   ACTION-IF-FOUND is not set, the macro will define HAVE_MPI.
-#
-#   The following example demonstrates usage of the macro:
-#
-#     # If --with-mpi=auto is used, try to find MPI, but use standard C compiler if it is not found.
-#     # If --with-mpi=yes is used, try to find MPI and fail if it isn't found.
-#     # If --with-mpi=no is used, use a standard C compiler instead.
-#     AC_ARG_WITH(mpi, [AS_HELP_STRING([--with-mpi],
-#         [compile with MPI (parallelization) support. If none is found,
-#         MPI is not used. Default: auto])
-#     ],,[with_mpi=auto])
-#
-#     AX_PROG_CXX_MPI([test x"$with_mpi" != xno],[use_mpi=yes],[
-#       use_mpi=no
-#       if test x"$with_mpi" = xyes; then
-#         AC_MSG_FAILURE([MPI compiler requested, but couldn't use MPI.])
-#       else
-#         AC_MSG_WARN([No MPI compiler found, won't use MPI.])
-#       fi
