      While introducing Spirit V2 we restructured the directory structure in order
      to accommodate two versions at the same time. All of <a href="../../../../../libs/spirit/classic/index.html" target="_top"><span class="emphasis"><em>Spirit.Classic</em></span></a>
      now lives in the directory
