# -*- python -*- # This example uses option parsing and CRTC searching. # `Screens.find_by_crtc` and `Screen.find_by_crtc`, are # not used, those are not useful for anything. They can # be used for seaching the number of connected monitors, # but `Screen.crtc_count` is much more effective. # This file is dual-licensed under GNU General Public License # version 3 and GNU Free Documentation License version 1.3. # Copyright © 2014 Mattias Andrée (maandree@member.fsf.org) # # This program is free software: you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation, either version 3 of the License, or # (at your option) any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
