/**
 * ==VimperatorPlugin==
 * @name         Ubiquity Glue
 * @description  Vimperator-plugin for Ubiquity
 * @depend       Ubiquity (ubiquity@labs.mozilla.com)
 * @version      0.1.1a
 * ==/VimperatorPlugin==
 * 
 * USAGE:
 *
 * :ubi[quity] {ubiquityCommand}
 *  {ubiquityCommand}をUbiquityに渡して実行
 *
 * :ubi[quity]
 *  ランチャを起動
 *
 *  - ランチャ起動キーでコマンドラインに":ubiquity "がでます(ランチャはポップアップしない)
 *    気に入らない場合は、XXX:の辺りのコードをコメントアウトしてください
 *  - Ubiquityコマンド名の補完が効きます。
 *  - Ubiquityコマンド入力後、引数を入力してのタブ補完をするとUbiquityのプレビューがでる(はず)
 *
 * FIXME:
 *  - プレビュー時の選択範囲の取得がイマイチ出来てない
 *  - プレビュー後の操作はマウス必須になってしまう(これはどうしようもない？)
 *
