-"""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. |
