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.
