# 12.6 `mimetools` -- Tools for parsing MIME messages

This module defines a subclass of the `rfc822` module's `Message` class and a number of utility functions that are useful for the manipulation for MIME multipart or encoded message.

It defines the following items:

class `Message`(fp[, seekable])
  Return a new instance of the `Message` class. This is a subclass of the `rfc822.Message` class, with some additional methods (see below). The seekable argument has the same meaning as for `rfc822.Message`.

`choose_boundary`()
  Return a unique string that has a high likelihood of being usable as a part boundary. The string has the form `'hostipaddr.uid.pid.timestamp.random'`.

`decode`(input, output, encoding)
  Read data encoded using the allowed MIME encoding from open file object input and write the decoded data to open file object output. Valid values for encoding include `'base64'`, `'quoted-printable'` and `'uuencode'`.

`encode`(input, output, encoding)
  Read data from open file object input and write it encoded using the allowed MIME encoding to open file object output. Valid values for encoding are the same as for `decode()`.

`copyliteral`(input, output)
  Read lines from open file input until EOF and write them to open file output.

`copybinary`(input, output)
  Read blocks until EOF from open file input and write them to open file output. The block size is currently fixed at 8192.

  Provides the base class for `mimetools.Message`.

Module `multifile`:
  Support for reading files which contain distinct parts, such as MIME data.
