<p>
        For example, if you used to include &lt;boost/spirit/actor.hpp&gt;, which
        is now a deprecated header, you should instead include &lt;boost/spirit/include/classic_actor.hpp&gt;
      </p>

        If you want to simply include the main sub-library name, then you can include:
      </p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
            &lt;boost/spirit/include/classic.hpp&gt;
          </li>
<li class="listitem">
