# 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 searches
#   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
