-Running subprocesses
---------------------
-
-Run subprocesses asynchronously using the :mod:`subprocess` module.
-
-.. note::
-
- On Windows, the default event loop uses
- :class:`selectors.SelectSelector` which only supports sockets. The
- :class:`ProactorEventLoop` should be used to support subprocesses.
-
-.. note::
-
- On Mac OS X older than 10.9 (Mavericks), :class:`selectors.KqueueSelector`
- does not support character devices like PTY, whereas it is used by the
- default event loop. The :class:`SelectorEventLoop` can be used with
- :class:`SelectSelector` or :class:`PollSelector` to handle character devices
- on Mac OS X 10.6 (Snow Leopard) and later.
-
-.. method:: BaseEventLoop.subprocess_exec(protocol_factory, \*args, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, \*\*kwargs)
-
- Create a subprocess from one or more string arguments, where the first string
- specifies the program to execute, and the remaining strings specify the
- program's arguments. (Thus, together the string arguments form the
- ``sys.argv`` value of the program, assuming it is a Python script.) This is
- similar to the standard library :class:`subprocess.Popen` class called with
- shell=False and the list of strings passed as the first argument;
- however, where :class:`~subprocess.Popen` takes a single argument which is
- list of strings, :func:`subprocess_exec` takes multiple string arguments.
-
- Other parameters:
-
- * *stdin*: Either a file-like object representing the pipe to be connected
- to the subprocess's standard input stream using
- :meth:`~BaseEventLoop.connect_write_pipe`, or the constant
- :const:`subprocess.PIPE` (the default). By default a new pipe will be
- created and connected.
-
- * *stdout*: Either a file-like object representing the pipe to be connected
- to the subprocess's standard output stream using
- :meth:`~BaseEventLoop.connect_read_pipe`, or the constant
- :const:`subprocess.PIPE` (the default). By default a new pipe will be
- created and connected.
-
- * *stderr*: Either a file-like object representing the pipe to be connected
- to the subprocess's standard error stream using
- :meth:`~BaseEventLoop.connect_read_pipe`, or one of the constants
- :const:`subprocess.PIPE` (the default) or :const:`subprocess.STDOUT`.
- By default a new pipe will be created and connected. When
- :const:`subprocess.STDOUT` is specified, the subprocess's standard error
- stream will be connected to the same pipe as the standard output stream.
-
- * All other keyword arguments are passed to :class:`subprocess.Popen`
- without interpretation, except for *bufsize*, *universal_newlines* and
- *shell*, which should not be specified at all.
-
- Returns a pair of ``(transport, protocol)``, where *transport* is an
- instance of :class:`BaseSubprocessTransport`.
-
- This method is a :ref:`coroutine <coroutine>`.
-
- See the constructor of the :class:`subprocess.Popen` class for parameters.
-
-.. method:: BaseEventLoop.subprocess_shell(protocol_factory, cmd, \*, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, \*\*kwargs)
-
- Create a subprocess from *cmd*, which is a string using the platform's
- "shell" syntax. This is similar to the standard library
- :class:`subprocess.Popen` class called with ``shell=True``.
-
- See :meth:`~BaseEventLoop.subprocess_exec` for more details about
- the remaining arguments.

- Returns a pair of ``(transport, protocol)``, where *transport* is an
