 #MIME type package
 
 Package for working with MIME type definitions and for processing
 streams of MIME multipart media types.
 
 ##Determining the MIME type for a file
 
 The `MimeTypeResolver` class can be used to determine the MIME type of
 a file. It supports both using the extension of the file name and
 looking at magic bytes from the begining of the file.
