447 # SYNOPSIS
448 #
449 # AX_BOOST_BASE([MINIMUM-VERSION])
450 #
451 # DESCRIPTION
452 #
453 # Test for the Boost C++ libraries of a particular version (or newer)
454 #
455 # If no path to the installed boost library is given the macro searchs
456 # under /usr, /usr/local, /opt and /opt/local and evaluates the
457 # $BOOST_ROOT environment variable. Further documentation is available at
458 # <http://randspringer.de/boost/index.html>.
459 #
460 # This macro calls:
461 #
462 # AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
463 #
464 # And sets:
465 #
466 # HAVE_BOOST
