    <div style="margin-left:  0px;"> The <b>BOOST_PP_REMOVE_PAREN</b>S macro
      removes the beginning parenthesis, if it exists, from the input data and
      expands to the result</div>
    <h4>Usage</h4>
    <div class="code"> <b>BOOST_PP_REMOVE_PARENS</b>(param) <a href="../topics/variadic_macros.html#VNotation"
        target="_self"><sup>(v)</sup></a></div>
    <h4>Arguments&nbsp;&nbsp;&nbsp;&nbsp;<span style="font-weight: normal;"></span></h4>
    <h4><span style="font-weight: normal;">&nbsp;&nbsp;&nbsp; param</span>&nbsp;&nbsp;
      <span style="font-weight: normal;">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;
        The input data.</span></h4>
    <h4>Remarks</h4>
    <div> If the input begins with a parenthesis, with any data within that
      parenthesis, the macro removes the parenthesis and expands to the result.
      If the input does not begin with a parenthesis the macro expands to the
      input.<br>
