This module defines two useful functions: guess_type(url, strict=1) -- guess the MIME type and encoding of a URL. guess_extension(type, strict=1) -- 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 iNt guess_typetguess_extensiontguess_all_extensionstadd_typetread_mime_typestinits/etc/mime.typess/etc/httpd/mime.typess/etc/httpd/conf/mime.typess/etc/apache/mime.typess/etc/apache2/mime.typess$/usr/local/etc/httpd/conf/mime.typess"/usr/local/lib/netscape/mime.typess/usr/local/etc/mime.typest MimeTypescBsqeZdZd edZedZedZedZedZedZ edZ edZ RS( sMIME-types datastore.
