		<div style="margin-left:  0px;">
			The <b>BOOST_PP_SEQ_FILTER_S</b> macro filters a <i>seq</i> according to a 
			supplied criterion.&nbsp; It reenters <b>BOOST_PP_SEQ_FOLD_LEFT</b> with 
			maximum efficiency.
		</div>
		<h4>
			Usage
		</h4>
		<div class="code">
			<b>BOOST_PP_SEQ_FILTER_S</b>(<i>s</i>, <i>pred</i>, <i>data</i>, <i>seq</i>)
		</div>
		<h4>
			Arguments
		</h4>
		<dl>
			<dt>s</dt>
			<dd>
				The next available <b>BOOST_PP_SEQ_FOLD_LEFT</b> fold step.
			</dd>
			<dt>pred</dt>
			<dd>
				A ternary predicate of the form <i>pred</i>(<i>s</i>, <i>data</i>, <i>elem</i>).&nbsp; 
				This predicate is expanded by <b>BOOST_PP_SEQ_FILTER</b> for each element in <i>seq</i>
				with the next available <b>BOOST_PP_SEQ_FOLD_LEFT</b> fold step, the auxiliary <i>data</i>, 
				and the current element in <i>seq</i>.&nbsp; This macro must return a integral 
				value in the range of <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>.&nbsp; If this 
				predicate expands to non-zero for a certain element, that element is included 
				in the resulting <i>seq</i>.
			</dd>
			<dt>data</dt>
			<dd>
				Auxiliary data passed to <i>pred</i>.
			</dd>
			<dt>seq</dt>
			<dd>
				The <i>seq</i> to be filtered.
			</dd>
		</dl>
		<h4>
			Remarks
		</h4>
		<div>
			This macro expands <i>pred</i> for each element in <i>seq</i>.&nbsp; It builds 
			a new <i>seq</i> out of each element for which <i>pred</i> returns non-zero.
		</div>
