     Handler that enables HTTP Range headers.
 
     Reference: http://stackoverflow.com/questions/1971240/python-seek-on-remote-file
-
-    This was extremely simple. The Range header is a HTTP feature to
-    begin with so all this class does is tell urllib2 that the
-    "206 Partial Content" response from the HTTP server is what we
-    expected.
-
-    Example:
-        import urllib2
-        import byterange
-
-        range_handler = range.HTTPRangeHandler()
-        opener = urllib2.build_opener(range_handler)
-
-        # install it
-        urllib2.install_opener(opener)
-
-        # create Request and set Range header
-        req = urllib2.Request('https://www.python.org/')
-        req.header['Range'] = 'bytes=30-50'
-        f = urllib2.urlopen(req)
