  <!-- Build Documentation -->
  <target name="asdoc" depends="compile">
    <echo>[create-docs] Generating ASDOC documentation</echo>
    <tstamp>
      <format property="docgen.time" pattern="MM/dd/yyyy hh:mm aa" unit="hour"/>
    </tstamp>
      <asdoc output="${doc.loc}" lenient="true" failonerror="true" keep-xml="true" skip-xsl="true" fork="true">
          <compiler.source-path path-element="${main.src.loc}" />
          <doc-sources path-element="${main.src.loc}"/>         
      </asdoc>
      <zip destfile="${bin.loc}/${project.name.versioned}.swc" update="true">
          <zipfileset dir="${doc.loc}/tempdita" prefix="docs">
            <include name="*.*"/>
