      <p>Once the pre-processing and XHTML processes are completed, most of the HTML Help processing is handled
        by the following targets:</p>
      <dl>
        <dlentry>
          <dt><codeph>dita.map.htmlhelp</codeph></dt>
          <dd>Create the HHP, HHC, and HHK files. The HHK file is sorted based on the language of the map.</dd>
        </dlentry>
        <dlentry>
          <dt><codeph>dita.htmlhelp.convertlang</codeph></dt>
          <dd>Ensures that the content can be processed correctly by the compiler, and that the appropriate code pages
            and languages are used.</dd>
        </dlentry>
        <dlentry>
          <dt><codeph>compile.HTML.Help</codeph></dt>
          <dd>Attempts to detect the HTML Help compiler. If the compiler is found, the full project is compiled into a
            single CHM file.</dd>
