		The <b>BOOST_PP_INCLUDE_SELF</b> macro includes a file indirectly.
	</div>
	<h4>Usage</h4>
		<div class="code">
			#include <b>BOOST_PP_INCLUDE_SELF</b>()
		</div>
	<h4>Arguments</h4>
		<dl>
			<dt>filename</dt>
			<dd>
				A quoted or angle-bracketed filename to be included by <b>BOOST_PP_INCLUDE_SELF</b>.
			</dd>
		</dl>
	<h4>Remarks</h4>
		<div>
			<b>BOOST_PP_INDIRECT_SELF</b> must be defined prior to using this macro.
		</div>
		<div>
			Most preprocessors will not allow a file to directly include itself--even when the file protects itself from such a scenario.&nbsp;
			This macro, in combination with <b>BOOST_PP_INDIRECT_SELF</b> allows a file to include itself indirectly.
		</div>
		<div>
			While <b>BOOST_PP_INDIRECT_SELF</b> is being included, <b>BOOST_PP_INCLUDE_SELF</b> defines the macro <b>BOOST_PP_IS_SELFISH</b> to <i>1</i>.&nbsp;
			When it returns from the inclusion, <b>BOOST_PP_IS_SELFISH</b> is undefined.
		</div>
