   5 # SYNOPSIS

   7 #   AX_BOOST_BASE([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
   8 #
   9 # DESCRIPTION
  10 #
  11 #   Test for the Boost C++ libraries of a particular version (or newer)
  12 #
  13 #   If no path to the installed boost library is given the macro searches
  14 #   under /usr, /usr/local, /opt and /opt/local and evaluates the
  15 #   $BOOST_ROOT environment variable. Further documentation is available at
  16 #   <http://randspringer.de/boost/index.html>.
  17 #
  18 #   This macro calls:
  19 #
  20 #     AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
  21 #
  22 #   And sets:
  23 #
  24 #     HAVE_BOOST
