-"""MIME-Type Parser
-
-This module provides basic functions for handling mime-types. It can handle
-matching mime-types against a list of media-ranges. See section 14.1 of the
-HTTP specification [RFC 2616] for a complete explanation.
-
- http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.1
-
-Contents:
- - parse_mime_type(): Parses a mime-type into its component parts.
- - parse_media_range(): Media-ranges are mime-types with wild-cards and a 'q'
- quality parameter.
- - quality(): Determines the quality ('q') of a mime-type when
- compared against a list of media-ranges.
- - quality_parsed(): Just like quality() except the second parameter must be
- pre-parsed.
- - best_match(): Choose the mime-type with the highest quality ('q')
- from a list of candidates.
