  <path id="project.class.path">
      <!-- Include our own classes, of course -->
      <pathelement location="${class.root}" />
      <!-- Include jars in the project library directory -->
      <fileset dir="${lib.dir}">
        <include name="*.jar"/>
      </fileset>
  </path>


  <!-- Create our runtime subdirectories and copy resources into them -->
