			The <b>BOOST_PP_SEQ_REST_N</b> macro expands to a <i>seq</i> of all but the 
			first <i>n</i> elements of a <i>seq</i>.
		</div>
		<h4>
			Usage
		</h4>
		<div class="code">
			<b>BOOST_PP_SEQ_REST_N</b>(<i>n</i>, <i>list</i>)
		</div>
		<h4>
			Arguments
		</h4>
		<dl>
			<dt>n</dt>
			<dd>
				The number of elements to remove.
			</dd>
			<dt>list</dt>
			<dd>
				The <i>seq</i> from which the elements are to be removed.
			</dd>
		</dl>
		<h4>
			Remarks
		</h4>
		<div>
			This macro extracts <i>n</i> elements from the beginning of <i>seq</i> and 
			returns the remainder of <i>seq</i> as a new <i>seq</i>
		</div>
