XML::RSS::LibXML uses XML::LibXML (libxml2) for parsing RSS instead of
XML::RSS' XML::Parser (expat), while trying to keep interface compatibility
with XML::RSS.

XML::RSS is an extremely handy tool, but it is unfortunately not exactly
the most lean or efficient RSS parser, especially in a long-running
process. So for a long time I had been using my own version of RSS parser
to get the maximum speed and efficiency - this is the re-packaged version
of that module, such that it adheres to the XML::RSS interface.

Use this module when you have severe performance requirements working with
RSS files.
