        <a>downloadPath</a>へZIPでアーカイブする。
        <a>downloadPath</a>がディレクトリの場合、"ページタイトル.zip"となる。
        省略された場合、以下の順に値を見て、そのディレクトリへダウンロードされる。
        <ul>
          <li>g:zipDownloadDir (liberator.globalVariables.zipDownloadDir)</li>
          <li>browser.download.lastDir (Preference)</li>
          <li>ホームディレクトリ</li>
        </ul>
      </p>
      <p>
        <oa>-l<oa>ist</oa></oa>オプションを指定すると、ダウンロードされるURLをリストする。
        (ダウンロードはされない)
