also used by the uu codec.

-:mod:`uu` --- Encode and decode uuencode files
-==============================================
-
-.. module:: uu
-   :synopsis: Encode and decode files in uuencode format.
-   :deprecated:
-
-.. moduleauthor:: Lance Ellinghouse
-
-**Source code:** :source:`Lib/uu.py`
-
-.. deprecated-removed:: 3.11 3.13
-   The :mod:`uu` module is deprecated
-   (see :pep:`PEP 594 <594#uu-and-the-uu-encoding>` for details).
-   :mod:`base64` is a modern alternative.
-
---------------
-
-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 ``'-'``
-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 ``'rb'`` or ``'wb'`` on Windows.
-
-.. index::
-   single: Jansen, Jack
-   single: Ellinghouse, Lance
-
-This code was contributed by Lance Ellinghouse, and modified by Jack Jansen.
-
-The :mod:`uu` module defines the following functions:
-
-
-.. function:: encode(in_file, out_file, name=None, mode=None, *, backtick=False)
-
-   Uuencode file *in_file* into file *out_file*.  The uuencoded file will have
-   the header specifying *name* and *mode* as the defaults for the results of
-   decoding the file. The default defaults are taken from *in_file*, or ``'-'``
-   and ``0o666`` respectively.  If *backtick* is true, zeros are represented by
-   ``'`'`` instead of spaces.
-
-   .. versionchanged:: 3.7
-      Added the *backtick* parameter.
-
-
-.. function:: decode(in_file, out_file=None, mode=None, quiet=False)
-
-   This call decodes uuencoded file *in_file* placing the result on file
-   *out_file*. If *out_file* is a pathname, *mode* is used to set the permission
-   bits if the file must be created. Defaults for *out_file* and *mode* are taken
-   from the uuencode header.  However, if the file specified in the header already
-   exists, a :exc:`uu.Error` is raised.
-
-   :func:`decode` may print a warning to standard error if the input was produced
-   by an incorrect uuencoder and Python could recover from that error.  Setting
-   *quiet* to a true value silences this warning.
-
-
-.. exception:: Error()
-
-   Subclass of :exc:`Exception`, this can be raised by :func:`uu.decode` under
-   various situations, such as described above, but also including a badly
-   formatted header, or truncated input file.
-
-
-.. seealso::
-
-   Module :mod:`binascii`
-      Support module containing ASCII-to-binary and binary-to-ASCII conversions.
