  =:support
    parseSelector supports the following user agents:
      * Internet Explorer 6 and above
      * Firefox 1.0 and above, and equivalent Gecko engine versions
      * Safari 2.0 and above
      * Opera 8.0 and above
      * Konqueror 3.5.5 and above
    It might work in other browsers and versions, but there are no guarantees. There is
    no verification made when parseSelector is run to ascertain the browser is supported.
  
  =:notes
    The parsing of CSS selectors as streams has been based on Dean Edwards
    excellent work with cssQuery. See <http://dean.edwards.name/my/cssQuery/>
    for more info.
