12.6 <tt class="module">mimetools</tt> --
         Tools for parsing MIME messages</A>

<A NAME="module-mimetools"></A>

<P>
<div class="versionnote"><b>Deprecated since release 2.3.</b>
The <tt class="module"><a href="module-email.html">email</a></tt> package should be used in
                 preference to the <tt class="module">mimetools</tt> module.  This
                 module is present only to maintain backward
                 compatibility.</div><p></p>

<P>
This module defines a subclass of the
<tt class="module"><a href="module-rfc822.html">rfc822</a></tt><a id='l2h-4011' xml:id='l2h-4011'></a> module's
<tt class="class">Message</tt> class and a number of utility functions that are
useful for the manipulation for MIME multipart or encoded message.

<P>
It defines the following items:

<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><span class="typelabel">class</span>&nbsp;<tt id='l2h-4005' xml:id='l2h-4005' class="class">Message</tt></b>(</nobr></td>
  <td><var>fp</var><big>[</big><var>, seekable</var><big>]</big><var></var>)</td></tr></table></dt>
<dd>
Return a new instance of the <tt class="class">Message</tt> class.  This is a
subclass of the <tt class="class">rfc822.Message</tt> class, with some additional
methods (see below).  The <var>seekable</var> argument has the same meaning
as for <tt class="class">rfc822.Message</tt>.
</dl>

<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><tt id='l2h-4006' xml:id='l2h-4006' class="function">choose_boundary</tt></b>(</nobr></td>
  <td><var></var>)</td></tr></table></dt>
<dd>
Return a unique string that has a high likelihood of being usable as a
part boundary.  The string has the form
<code>'<var>hostipaddr</var>.<var>uid</var>.<var>pid</var>.<var>timestamp</var>.<var>random</var>'</code>.
</dl>

<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">

  <td><var>input, output, encoding</var>)</td></tr></table></dt>
<dd>
Read data encoded using the allowed MIME <var>encoding</var> from open file
object <var>input</var> and write the decoded data to open file object
<var>output</var>.  Valid values for <var>encoding</var> include
<code>'base64'</code>, <code>'quoted-printable'</code>, <code>'uuencode'</code>,
<code>'x-uuencode'</code>, <code>'uue'</code>, <code>'x-uue'</code>, <code>'7bit'</code>, and
<code>'8bit'</code>.  Decoding messages encoded in <code>'7bit'</code> or <code>'8bit'</code>
has no effect.  The input is simply copied to the output.

<dd>
Read data from open file object <var>input</var> and write it encoded using
the allowed MIME <var>encoding</var> to open file object <var>output</var>.
Valid values for <var>encoding</var> are the same as for <tt class="method">decode()</tt>.
