60MIME-Type Parser
61
62This module provides basic functions for handling mime-types. It can handle
63matching mime-types against a list of media-ranges. See section 14.1 of the
64HTTP specification [RFC 2616] for a complete explanation.
65
66 http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.1
67
68Contents:
69 - parse_mime_type(): Parses a mime-type into its component parts.
70 - parse_media_range(): Media-ranges are mime-types with wild-cards and a 'q'
71 quality parameter.
72 - quality(): Determines the quality ('q') of a mime-type when
73 compared against a list of media-ranges.
74 - quality_parsed(): Just like quality() except the second parameter must be
75 pre-parsed.
76 - best_match(): Choose the mime-type with the highest quality ('q')
77 from a list of candidates.
