+# SYNOPSIS
+#
+#   ACX_MPI([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro tries to find out how to compile programs that use MPI
+#   (Message Passing Interface), a standard API for parallel process
+#   communication (see http://www-unix.mcs.anl.gov/mpi/)
+#
+#   On success, it sets the MPICC, MPICXX, MPIF77, or MPIFC output variable
+#   to the name of the MPI compiler, depending upon the current language.
+#   (This may just be $CC/$CXX/$F77/$FC, but is more often something like
+#   mpicc/mpiCC/mpif77/mpif90.) It also sets MPILIBS to any libraries that
+#   are needed for linking MPI (e.g. -lmpi or -lfmpi, if a special
+#   MPICC/MPICXX/MPIF77/MPIFC was not found).
+#
+#   If you want to compile everything with MPI, you should set:
+#
+#       CC="MPICC" #OR# CXX="MPICXX" #OR# F77="MPIF77" #OR# FC="MPIFC"
+#       LIBS="$MPILIBS $LIBS"
+#
+#   NOTE: The above assumes that you will use $CC (or whatever) for linking
+#   as well as for compiling. (This is the default for automake and most
+#   Makefiles.)
+#
+#   The user can force a particular library/compiler by setting the
+#   MPICC/MPICXX/MPIF77/MPIFC and/or MPILIBS environment variables.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if an MPI library is
+#   found, and ACTION-IF-NOT-FOUND is a list of commands to run if it is not
+#   found. If ACTION-IF-FOUND is not specified, the default action will
+#   define HAVE_MPI.
