Require a supervisor process to be running.
Keyword arguments will be used to build the program configuration
file. Some useful arguments are:
- ``command``: complete command including arguments (**required**)
- ``directory``: absolute path to the working directory
- ``user``: run the process as this user
- ``stdout_logfile``: absolute path to the log file
You should refer to the `supervisor documentation`_ for the
complete list of allowed arguments.
.. note:: the default values for the following arguments differs from
the ``supervisor`` defaults:
- ``autorestart``: defaults to ``true``
- ``redirect_stderr``: defaults to ``true``
Example::
from fabtools import require
