Encode and decode uuencode files
</A>
This module encodes and decodes files in uuencode format, allowing
arbitrary binary data to be transferred over ASCII-only connections.
Wherever a file argument is expected, the methods accept a file-like
object. For backwards compatibility, a string containing a pathname
is also accepted, and the corresponding file will be opened for
reading and writing; the pathname
<code>'-'
</code> is understood to mean the
standard input or output. However, this interface is deprecated; it's
better for the caller to open the file itself, and be sure that, when
required, the mode is
<code>'rb'
</code> or
<code>'wb'
</code> on Windows.
This code was contributed by Lance Ellinghouse, and modified by Jack

This call decodes uuencoded file
<var>in_file
</var> placing the result on
file
<var>out_file
</var>. If
<var>out_file
</var> is a pathname,
<var>mode
</var> is
used to set the permission bits if the file must be
created. Defaults for
<var>out_file
</var> and
<var>mode
</var> are taken from
the uuencode header. However, if the file specified in the header
already exists, a
<tt class=
"exception">uu.Error
</tt> is raised.
<tt class=
"function">decode()
</tt> may print a warning to standard error if the
input was produced by an incorrect uuencoder and Python could
recover from that error. Setting
