+    <div style="margin-left: 0px;"> The <b>BOOST_PP_ARRAY_TO_SEQ</b> macro
+      converts an <i>array</i> to a <i>seq</i>. </div>

+    <div class="code"> <b>BOOST_PP_ARRAY_TO_SEQ</b>(<i>array</i>) </div>
+    <h4> Arguments </h4>
+    <dl>
+      <dt>array</dt>
+      <dd> The <i>array</i> to be converted.</dd>
+    </dl>
+    <h4>Remarks</h4>
+    <p>&nbsp;&nbsp;&nbsp; If the <i>array</i> to be converted is empty, as
+      represented by '( 0, () )', the resulting <i>seq</i> is undefined since a
+      <i>seq</i> cannot be empty.</p>
