    == Subject ==
      Make notify hatebu-count when specified site's hatebu-count changed.
      Usage is just put this script into vimperator's plugin directory.

    == Global variables ==
      g:hatebuWatchDogInterval:
        Number. Watching interval. Default:600 Min:60
      g:hatebuWtachDogTargets:
        String. Sites where it wants you to watch.
        If you want watch only one site, you should specify like following.
        >||
          :let g:hatebuWatchDogTargets = "http://d.hatena.ne.jp/snaka72/"
        ||<
        If you want watch more than one site, you should specify like following.
        >||
          :let g:hatebuWatchDogTargets = "['http://d.hatena.ne.jp/snaka72/', 'http://vimperator.g.hatena.ne.jp/snaka72/']"
        ||<
      g:hatebuWatchDogAlways:
        Boole. Make notify every time. (for debug) Default:false

  ]]></detail>
  <detail lang="ja"><![CDATA[
    == 概要 ==
      指定されたサイトの被はてブ数を監視してその数値に変動があったらお知らせします
      使い方はこのスクリプトをVimperatorのpluginディレクトリに格納するだけです

    == グローバル変数 ==
      g:hatebuWatchDogInterval:
        Number. 監視の間隔(). デフォルト600 設定可能な最小値:60
      g:hatebuWtachDogTargets:
        String. Sites where it wants you to watch
        監視対象のサイトが一つだけの場合は以下のように設定します
        >||
          :let g:hatebuWatchDogTargets = "http://d.hatena.ne.jp/snaka72/"
        ||<
        監視対象のサイトがが複数の場合は以下のように設定します
        >||
          :let g:hatebuWatchDogTargets = "['http://d.hatena.ne.jp/snaka72/', 'http://vimperator.g.hatena.ne.jp/snaka72/']"
        ||<
      g:hatebuWatchDogAlways:
        Boole. 毎回報告を挙げるかどうかデフォルト:false 主にでバッグ用

    == ToDo ==
      - 新着ブックマークのユーザidとコメントの表示
      - 監視フレームワークにのっける
