Source code for _roster.file

# -*- coding: utf-8 -*-
'''
Load the list of devices from an arbitrary SLS file.

To use this module, you only need to configure the --roster option to ``file``
(on the CLI or Master config), and if the Roster SLS file is in a different
location than ``/etc/salt/roster``, you'd also need to specify ``--roster-file``
(or ``roster_file`` in the Master config).
