-:mod:`pipes` --- Interface to shell pipelines
-=============================================
-
-.. module:: pipes
-   :platform: Unix
-   :synopsis: A Python interface to Unix shell pipelines.
-   :deprecated:
-
-.. sectionauthor:: Moshe Zadka <moshez@zadka.site.co.il>
-
-**Source code:** :source:`Lib/pipes.py`
-
-.. deprecated-removed:: 3.11 3.13
-   The :mod:`pipes` module is deprecated
-   (see :pep:`PEP 594 <594#pipes>` for details).
-   Please use the :mod:`subprocess` module instead.
-
---------------
-
-The :mod:`pipes` module defines a class to abstract the concept of a *pipeline*
---- a sequence of converters from one file to  another.
-
-Because the module uses :program:`/bin/sh` command lines, a POSIX or compatible
-shell for :func:`os.system` and :func:`os.popen` is required.
-
-.. availability:: Unix, not VxWorks.
-
-The :mod:`pipes` module defines the following class:
-
-
-.. class:: Template()
-
-   An abstraction of a pipeline.
-
-Example::
-
-   >>> import pipes
-   >>> t = pipes.Template()
-   >>> t.append('tr a-z A-Z', '--')
-   >>> f = t.open('pipefile', 'w')
-   >>> f.write('hello world')
-   >>> f.close()
-   >>> open('pipefile').read()
-   'HELLO WORLD'
-
-
-.. _template-objects:
-
-Template Objects
-----------------
-
-Template objects following methods:
-
-
-.. method:: Template.reset()
-
-   Restore a pipeline template to its initial state.
-
-
-.. method:: Template.clone()
-
-   Return a new, equivalent, pipeline template.
-
-
-.. method:: Template.debug(flag)
-
-   If *flag* is true, turn debugging on. Otherwise, turn debugging off. When
-   debugging is on, commands to be executed are printed, and the shell is given
-   ``set -x`` command to be more verbose.
-
-
-.. method:: Template.append(cmd, kind)
-
-   Append a new action at the end. The *cmd* variable must be a valid bourne shell
-   command. The *kind* variable consists of two letters.
-
-   The first letter can be either of ``'-'`` (which means the command reads its
-   standard input), ``'f'`` (which means the commands reads a given file on the
-   command line) or ``'.'`` (which means the commands reads no input, and hence
-   must be first.)
-
-   Similarly, the second letter can be either of ``'-'`` (which means  the command
-   writes to standard output), ``'f'`` (which means the  command writes a file on
-   the command line) or ``'.'`` (which means the command does not write anything,
-   and hence must be last.)
-
-
-.. method:: Template.prepend(cmd, kind)
-
-   Add a new action at the beginning. See :meth:`append` for explanations of the
-   arguments.
-
-
-.. method:: Template.open(file, mode)
-
-   Return a file-like object, open to *file*, but read from or written to by the
-   pipeline.  Note that only one of ``'r'``, ``'w'`` may be given.
-
-
-.. method:: Template.copy(infile, outfile)
-
-   Copy *infile* to *outfile* through the pipe.

-"""Conversion pipeline templates.
-
-The problem:
-------------
-
-Suppose you have some data that you want to convert to another format,
-such as from GIF image format to PPM image format.  Maybe the
-conversion involves several steps (e.g. piping it through compress or
-uuencode).  Some of the conversion steps may require that their input
-is a disk file, others may be able to read standard input; similar for
-their output.  The input to the entire conversion may also be read
-from a disk file or from an open file, and similar for its output.
-
-The module lets you construct a pipeline template by sticking one or
-more conversion steps together.  It will take care of creating and
-removing temporary files if they are necessary to hold intermediate
-data.  You can then use the template to do conversions from many
-different sources to many different destinations.  The temporary
-file names used are different each time the template is used.
-
-The templates are objects so you can create templates for many
-different conversion steps and store them in a dictionary, for
-instance.
-
-
-Directions:
------------
-
-To create a template:
-    t = Template()
-
-To add a conversion step to a template:
-   t.append(command, kind)
-where kind is a string of two characters: the first is '-' if the
-command reads its standard input or 'f' if it requires a file; the
-second likewise for the output. The command must be valid /bin/sh
-syntax.  If input or output files are required, they are passed as
-$IN and $OUT; otherwise, it must be  possible to use the command in
-a pipeline.
-
-To add a conversion step at the beginning:
-   t.prepend(command, kind)
-
-To convert a file to another file using a template:
-  sts = t.copy(infile, outfile)
-If infile or outfile are the empty string, standard input is read or
-standard output is written, respectively.  The return value is the
-exit status of the conversion pipeline.
-
-To open a file for reading or writing through a conversion pipeline:
-   fp = t.open(file, mode)
-where mode is 'r' to read the file, or 'w' to write it -- just like
-for the built-in function open() or for os.popen().
-
-To create a new template object initialized to a given one:
-   t2 = t.clone()
