+			The <b>BOOST_PP_SEQ_FOLD_LEFT</b> macro folds (or accumulates) the elements of 
+			a <i>seq</i> left-to-right.
+		</div>
+		<h4>
+			Usage
+		</h4>
+		<div class="code">
+			<b>BOOST_PP_SEQ_FOLD_LEFT</b>(<i>op</i>, <i>state</i>, <i>seq</i>)
+		</div>
+		<h4>
+			Arguments
+		</h4>
+		<dl>
+			<dt>op</dt>
+			<dd>
+				A ternary operation of the form <i>op</i>(<i>s</i>, <i>state</i>, <i>elem</i>).&nbsp; 
+				This macro is called for each element in <i>seq</i>--each time returning a new <i>state</i>.&nbsp; 
+				This operation is expanded by <b>BOOST_PP_SEQ_FOLD_LEFT</b> with the next 
+				available fold step, the current <i>state</i>, and the current element.
+			</dd>
+			<dt>state</dt>
+			<dd>
+				The initial state of the fold.
+			</dd>
+			<dt>seq</dt>
+			<dd>
+				The <i>seq</i> to be folded.
+			</dd>
+		</dl>
+		<h4>
+			Remarks
+		</h4>
+		<div>
+			For the <i>seq</i>, (<i>0</i>)(<i>1</i>)(<i>2</i>), this macro expands to:
+			<div>
+				<i>op</i>(<i>s</i>, <i>op</i>(<i>s</i>, <i>op</i>(<i>s</i>, <i>state</i>, <i>0</i>),
+				<i>1</i>), <i>2</i>)
+			</div>
+		</div>
+		<div>
+			For maximum efficiency, <b>BOOST_PP_SEQ_FOLD_LEFT</b> can be reentered with <b>BOOST_PP_SEQ_FOLD_LEFT_<i>s</i></b>.
+		</div>
