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.

    Carves up a mime-type and returns a tuple of the (type, subtype, params)
    where 'params' is a dictionary of all the parameters for the media range.
    For example, the media range 'application/xhtml;q=0.5' would get parsed
    into:

       ('application', 'xhtml', {'q', '0.5'})

    Carves up a media range and returns a tuple of the (type, subtype,

    range.  For example, the media range 'application/*;q=0.5' would get parsed
    into:

       ('application', '*', {'q', '0.5'})

    In addition this function also guarantees that there is a value for 'q'
    in the params dictionary, filling it in with a proper default if
    necessary.

    Find the best match for a given mime-type against a list of media_ranges
    that have already been parsed by parse_media_range(). Returns a tuple of
    the fitness value and the value of the 'q' quality parameter of the best
    match, or (-1, 0) if no match was found. Just as for quality_parsed(),
    'parsed_ranges' must be a list of parsed media ranges.

    Takes a list of supported mime-types and finds the best match for all the
    media-ranges listed in header. The value of header must be a string that
    conforms to the format of the HTTP Accept: header. The value of 'supported'
    is a list of mime-types. The list of supported mime-types should be sorted
    in order of increasing desirability, in case of a situation where there is
    a tie.

    >>> best_match(['application/xbel+xml', 'text/xml'],
                   'text/*;q=0.5,*/*; q=0.1')
