   8     <div style="margin-left: 0px;"> The <b>BOOST_PP_SEQ_REST_N</b> macro
   9       expands to a <i>seq</i> of all but the first <i>n</i> elements of a <i>seq</i>.
  10     </div>
  11     <h4> Usage </h4>
  12     <div class="code"> <b>BOOST_PP_SEQ_REST_N</b>(<i>n</i>, <i>seq</i>) </div>
  13     <h4> Arguments </h4>
  14     <dl>
  15       <dt>n</dt>
  16       <dd> The number of elements to remove. </dd>
  17       <dt>seq</dt>
  18       <dd> The <i>seq</i> from which the elements are to be removed. </dd>
  19     </dl>
  20     <h4> Remarks </h4>
  21     <div> This macro extracts <i>n</i> elements from the beginning of <i>seq</i>
  22       and returns the remainder of <i>seq</i> as a new <i>seq.<br>
  23         <br>
  24       </i>It is undefined behavior if <i>n </i>is greater or equal to the size
  25       of the <i>seq</i>. </div>
