++# 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.
