468 # SYNOPSIS
469 #
470 # AX_BOOST_BASE([MINIMUM-VERSION])
471 #
472 # DESCRIPTION
473 #
474 # Test for the Boost C++ libraries of a particular version (or newer)
475 #
476 # If no path to the installed boost library is given the macro searchs
477 # under /usr, /usr/local, /opt and /opt/local and evaluates the
478 # $BOOST_ROOT environment variable. Further documentation is available at
479 # <http://randspringer.de/boost/index.html>.
480 #
481 # This macro calls:
482 #
483 # AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
484 #
485 # And sets:
486 #
487 # HAVE_BOOST
