    <detail><![CDATA[
== Objects ==
- liberator.plugins.libly.$U
- liberator.plugins.libly.Request
- liberator.plugins.libly.Response
- liberator.plugins.libly.Wedata

== Logger ==
getLogger(prefix):
    log(msg, level), echo(msg, flg), echoerr(msg)
    のメソッドを持つ logger インスタンスを取得します。
    ログの書式は prefix + ': ' + yyyy/MM/dd + msg となります。

== Object Utility ==
extend(dst, src):
    オブジェクトを拡張します。
A(iterable):
    オブジェクトを配列にします。
around(obj, name, func):
  obj がもつ name 関数を、func に置き換えます。
  func は
    function (next, args) {...}
  という形で呼ばれます。
  next はオリジナルの関数を呼び出すための関数、
  args はオリジナルの引数列です。
  next には引数を渡す必要はありません。
bind(obj, func):
    func に obj を bind します。
    func内からは this で obj が参照できるようになります。
eval(text):
    Sandbox による、window.eval を極力利用するようにします。
    Snadbox が利用できない場合は、unsafe な window の eval が直接利用されます。
evalJson(str, toRemove):
    str を decode します。
    toRemove が true の場合、文字列の前後を1文字削除します。
    "(key:value)" 形式の場合などに true を指定して下さい。
dateFormat(dtm, fmt):
    Date型インスタンスを、指定されたフォーマットで文字列に変換します。
    fmt を省略した場合、"%y/%M/%d %h:%m:%s" となります。
runnable(generator):
    gererator を実行し、再帰的に resume する為の引数を渡します。

==  Browser ==
getSelectedString:
    window の選択文字列を返却します。
getUserAndPassword(hostname, formSubmitURL, username):
    login-manager から [username, password] を取得します。
    引数の username が省略された場合、検索された 1件目を返却します。
    データが存在しない場合は、null を返却します。

== System ==
readDirectory(path, fileter, func):
    path で指定したディレクトリから、filter で指定された正規表現に match する場合、
    func をファイル名を引数にコールバックします。
    filter は Function を指定することも可能です。

== HTML, XML, DOM, E4X ==
pathToURL(a, baseURL, doc):
    相対パスを絶対パスに変換します。
getHTMLFragment(html):
    <html>※1</html>
    ※1 の文字列を取得します。
stripTags(str, tags):
    str から tags で指定されたタグを取り除いて返却します。
    tags は文字列、または配列で指定して下さい。
createHTMLDocument(str, xmlns):
    引数 str より、HTMLFragment を作成します。
getFirstNodeFromXPath(xpath, context):
    xpath を評価しオブジェクトをを返却します。
getNodesFromXPath(xpath, context, callback, thisObj):
    xpath を評価し snapshot の配列を返却します。
xmlSerialize(xml):
    xml を文字列化します。
xmlToDom(node, doc, nodes):
    for vimperator1.2.
    @see vimperator2.0pre util.
getElementPosition(elem):
    elem の offset を返却します。
    return {top: 0, left: 0}
