+"""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.
