-# SYNOPSIS
-#
-# AX_OPENMP([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
-#
-# DESCRIPTION
-#
-# This macro tries to find out how to compile programs that use OpenMP a
-# standard API and set of compiler directives for parallel programming
-# (see http://www-unix.mcs/)
-#
-# On success, it sets the OPENMP_CFLAGS/OPENMP_CXXFLAGS/OPENMP_F77FLAGS
-# output variable to the flag (e.g. -omp) used both to compile *and* link
-# OpenMP programs in the current language.
-#
-# NOTE: You are assumed to not only compile your program with these flags,
-# but also link it with them as well.
-#
-# If you want to compile everything with OpenMP, you should set:
-#
-# CFLAGS="$CFLAGS $OPENMP_CFLAGS"
-# #OR# CXXFLAGS="$CXXFLAGS $OPENMP_CXXFLAGS"
-# #OR# FFLAGS="$FFLAGS $OPENMP_FFLAGS"
-#
-# (depending on the selected language).
-#
-# The user can override the default choice by setting the corresponding
-# environment variable (e.g. OPENMP_CFLAGS).
-#
-# ACTION-IF-FOUND is a list of shell commands to run if an OpenMP flag is
-# found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it is
-# not found. If ACTION-IF-FOUND is not specified, the default action will
-# define HAVE_OPENMP.
