        <para>
            <command>lxc-autostart</command> processes containers
            with lxc.start.auto set. It lets the user start, shutdown,
            kill, restart containers in the right order, waiting the
            right time. Supports filtering by lxc.group or just run
            against all defined containers. It can also be used by
            external tools in list mode where no action will be performed
            and the list of affected containers (and if relevant, delays)
            will be shown.
        </para>

        <para>
            The <optional>-r</optional>, <optional>-s</optional>
            and <optional>-k</optional> options specify the action to perform.
            If none is specified, then the containers will be started.
            <optional>-a</optional> and <optional>-g</optional> are used to
            specify which containers will be affected. By default only
            containers without a lxc.group set will be affected.
            <optional>-t TIMEOUT</optional> specifies the maximum amount
            of time to wait for the container to complete the shutdown
            or reboot.
        </para>
