+ * Edje example demonstrating how to use multiseat features following
+ * a dynamic approach.
+ *
+ * It's an example of how themes can be implemented even if the number
+ * of seats using the UI is unknown.
+ *
+ * You'll need at least one Evas engine built for it (excluding the
+ * buffer one) that supports multiseat. It may be wayland or
+ * X11 with VNC support. Using other engines will lead you to a
+ * situation where all seats are reported as the same one ("default").
