<p>The <a class="reference internal" href="#module-mimify" title="mimify: Mimification and unmimification of mail messages. (deprecated)"><code class="xref py py-mod docutils literal notranslate"><span class="pre">mimify</span></code></a> module defines two functions to convert mail messages to and
from MIME format. The mail message can be either a simple message or a
so-called multipart message. Each part is treated separately. Mimifying (a part
of) a message entails encoding the message as quoted-printable if it contains
any characters that cannot be represented using 7-bit ASCII. Unmimifying (a
part of) a message entails undoing the quoted-printable encoding. Mimify and
unmimify are especially useful when a message has to be edited before being
sent. Typical use would be:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">unmimify</span> <span class="n">message</span>
<span class="n">edit</span> <span class="n">message</span>

</pre></div>
</div>
<p>to encode (mimify) and decode (unmimify) respectively. <em>infile</em> defaults to
standard input, <em>outfile</em> defaults to standard output. The same file can be
specified for input and output.</p>
<p>If the <strong>-l</strong> option is given when encoding, if there are any lines longer than
the specified <em>length</em>, the containing part will be encoded.</p>
<p>If the <strong>-b</strong> option is given when decoding, any base64 parts will be decoded as
well.</p>
