2 * Edje example demonstrating how to use multiseat features.
3 *
4 * You'll need at least one Evas engine built for it (excluding the
5 * buffer one) that supports multiseat. It may be wayland or
6 * X11 with VNC support. Using other engines will lead you to a
7 * situation where all seats are reported as the same one ("default").
