+		The <b>BOOST_PP_INDIRECT_SELF</b> macro is a user-defined <i>named external argument</i> used by <b>BOOST_PP_INCLUDE_SELF</b>.&nbsp;
+	</div>
+	<h4>Usage</h4>
+		<div class="code">
+			#define <b>BOOST_PP_INDIRECT_SELF</b> <i>filename</i>
+		</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>
+			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_INCLUDE_SELF</b> allows a file to include itself indirectly.
+		</div>
+		<div>
+			This macro is automatically undefined for reuse by a call to <b>BOOST_PP_INCLUDE_SELF</b>.
