+ 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.
+ 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>.
+ When it returns from the inclusion, <b>BOOST_PP_IS_SELFISH</b> is undefined.
+ </div>
