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 N knownfilesinited MimeTypes guess_typeguess_all_extensionsguess_extensionadd_typeinitread_mime_types suffix_map encodings_map types_map common_typesz/etc/mime.typesz/etc/httpd/mime.typesz/etc/httpd/conf/mime.typesz/etc/apache/mime.typesz/etc/apache2/mime.typesz$/usr/local/etc/httpd/conf/mime.typesz"/usr/local/lib/netscape/mime.typesz/usr/local/etc/mime.typesFc@s`eZdZdZdddZdddZddd Zdd d Zdd d ZdddZ dddZ dddZ dS)rzMIME-types datastore.

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.)
