This module provides a complete implementation of the HTTP content
negotiation algorithm specified in draft-ietf-http-v11-spec-00.ps
chapter 12. Content negotiation allows for the selection of a
preferred content representation based upon attributes of the
negotiable variants and the value of the various Accept* header
fields in the request.

It requires perl-http-message, perl-lwp-mediatypes, perl-encode-locale,
perl-uri-escape, perl-http-date and perl-html-parser.
