This module defines two useful functions:
guess_type(url, strict=True) -- guess the MIME type and encoding of a URL.
guess_extension(type, strict=True) -- guess the extension for a given MIME type.
It also contains the following, for tuning the behavior:
Data:
knownfiles -- list of files to parse
inited -- flag set when init() has been called
suffix_map -- dictionary mapping suffixes to suffixes
encodings_map -- dictionary mapping suffixes to encodings
types_map -- dictionary mapping suffixes to types
Functions:
init([files]) -- parse a list of files, default knownfiles (on Windows, the
default values are taken from the registry)
read_mime_types(file) -- parse one file, return a dictionary or None

This datastore can handle information from mime.types-style files
and supports basic determination of MIME type from a filename or
URL, and can guess a reasonable extension given a MIME type.

Return value is a tuple (type, encoding) where type is None if
the type can't be guessed (no or unknown suffix) or a string
of the form type/subtype, usable for a MIME Content-type
header; and encoding is None for no encoding or the name of
the program used to encode (e.g. compress or gzip). The
mappings are table driven. Encoding suffixes are case
sensitive; type suffixes are first tried case sensitive, then
case insensitive.
The suffixes .tgz, .taz and .tz (case sensitive!) are all
mapped to '.tar.gz'. (This is table-driven too, using the
dictionary suffix_map.)
Optional `strict' argument when False adds a bunch of commonly found,
but non-standard types.
