9    ``command_options`` is a string containing ``pylint`` command line options;
10    ``return_std`` (boolean) indicates return of created standard output
11    and error (see below);
12    ``stdout`` and ``stderr`` are 'file-like' objects in which standard output
13    could be written.
14
15    Calling agent is responsible for stdout/err management (creation, close).
16    Default standard output and error are those from sys,
17    or standalone ones (``subprocess.PIPE``) are used
18    if they are not set and ``return_std``.
19
20    If ``return_std`` is set to ``True``, this function returns a 2-uple
21    containing standard output and error related to created process,
22    as follows: ``(stdout, stderr)``.
