++maintenancemode application settings.
++
++If you not configure the settings below in your own project settings.py,
++they assume default values::
++
++    MAINTENANCE_MODE
++        Boolean. Enable/disable maintenance mode.
++        Default: False
++
++    MAINTENANCE_MODE_ALLOWED_PATHS
++        A list with paths can be acessed in maintenance mode.
++        Example: ['/admin', '/contact']
++        Default: []
++
++        Note::
++          The paths are case-sensitive, need starts with '/' and are
++          recusive: '/weblog' match '/weblog/2009/05/01', '/' match all
++          web site.
++
++     Some observations:
++
++     * If you uses a database, and the database is down, a maintenance
++       page is displayed;
++
++     * If user is logged in and staff member, the maintenance page is
++       never displayed.
