 +# ===========================================================================
 +#       http://www.gnu.org/software/autoconf-archive/ax_boost_base.html
 +# ===========================================================================
 +#
 +# SYNOPSIS
 +#
 +#   AX_BOOST_BASE([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
 +#
 +# DESCRIPTION
 +#
 +#   Test for the Boost C++ libraries of a particular version (or newer)
 +#
 +#   If no path to the installed boost library is given the macro searchs
 +#   under /usr, /usr/local, /opt and /opt/local and evaluates the
 +#   $BOOST_ROOT environment variable. Further documentation is available at
 +#   <http://randspringer.de/boost/index.html>.
 +#
 +#   This macro calls:
 +#
 +#     AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
 +#
 +#   And sets:
 +#
 +#     HAVE_BOOST
