+# ===========================================================================
+#      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
+#     ])

 # SYNOPSIS

 #
 # DESCRIPTION
 #
-#   This macro tries to find out how to compile C programs that use MPI
+#   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_CC
-#   and will replace the standard variable CC with the found compiler.
-#
-#   MPI-WANTED-TEST is used to test whether MPI is actually wanted by
-#   the user. If the test fails, the macro will not try to find MPI
-#   and call AC_PROG_CC to find a standard C compiler instead. If the
-#   test is omitted, the macro will try to find MPI and fail if it is
-#   not found. 
-#
-#   When MPI is found, ACTION-IF-FOUND will be executed, otherwise
