  63 <p>
  64 A content type is a platform specific string that defines the type
  65 of a file. On UNIX it is a <a class="ulink" href="http://www.wikipedia.org/wiki/Internet_media_type" target="_top">mime type</a> like "text/plain" or "image/png".
  66 On Win32 it is an extension string like ".doc", ".txt" or a perceived
  67 string like "audio". Such strings can be looked up in the registry at
