	<div style="margin-left:  0px;">
		The <b>BOOST_PP_LIST_APPEND</b> macro appends two <i>lists</i>.
	</div>
	<h4>Usage</h4>
		<div class="code">
			<b>BOOST_PP_LIST_APPEND</b>(<i>a</i>, <i>b</i>)
		</div>
	<h4>Arguments</h4>
		<dl>
			<dt>a</dt>
			<dd>
				The first <i>list</i>.
			</dd>
			<dt>b</dt>
			<dd>
				The second <i>list</i>.
			</dd>
		</dl>
	<h4>Remarks</h4>
		<div>
			This macro appends two lists.&nbsp;
			For example, if <i>a</i> is (<i>1</i>, (<i>2</i>, (<i>3</i>, <b>BOOST_PP_NIL</b>))) and <i>b</i> is (<i>4</i>, (<i>5</i>, <b>BOOST_PP_NIL</b>)),
			this macro will expand to:
			<div>
				(<i>1</i>, (<i>2</i>, (<i>3</i>, (<i>4</i>, (<i>5</i>, <b>BOOST_PP_NIL</b>)))))
			</div>
		</div>
		<div>
			Previously, this macro could not be used inside <b>BOOST_PP_WHILE</b>.&nbsp;
			There is no longer any such restriction.&nbsp;
			It is more efficient, however, to use <b>BOOST_PP_LIST_APPEND_D</b> in such a situation.
