I was trying to mirror www.trig.com and in the index.html the tags for
conditional CSS inclusion were not properly detected and handeled. Example: 

  <!--[if lt IE 7]>
  <link rel="stylesheet" href=http://static2.trig.com/stylesheets/ie.css
type="text/css" media="screen" charset="utf-8" />
  <![endif]-->
  <!--[if IE 7]>
  <link rel="stylesheet" href=http://static2.trig.com/stylesheets/ie7.css
type="text/css" media="screen" charset="utf-8" />
  <![endif]-->

Were not converted to :

  <!--[if lt IE 7]>
  <link rel="stylesheet" href="../static2.trig.com/stylesheets/ie.css"
type="text/css" media="screen" charset="utf-8" />
  <![endif]-->
  <!--[if IE 7]>
  <link rel="stylesheet" href="../static2.trig.com/stylesheets/ie7.css"
type="text/css" media="screen" charset="utf-8" />
  <![endif]-->
