        but the default policies have been chosen so that its easily usable with
        input iterators such as <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">istreambuf_iterator</span></code>.
        For the complete source code of this example please refer to <a href="../../../../example/support/multi_pass.cpp" target="_top">multi_pass.cpp</a>.
