-# SYNOPSIS
-#
-# AX_BOOST_BASE([MINIMUM-VERSION])
-#
-# 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, and /opt, 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
-#
-# LAST MODIFICATION
