+/* Devices and consoles are similar entities.  The idea is that
+   a console represents a physical keyboard/mouse/other-input-source
+   while a device represents a display where frames appear on.
+   In the X world, a console is a "Display" while a device is a
+   "Screen".  Implementationally, it can sometimes get confusing:
+   under X, multiple devices on a single console are different
+   "Display" connections to what is in reality the same Display on
+   the same server.  Because of this, input comes from the device
+   and not from the console.  This is OK because events are basically
+   always tagged to a particular X window (i.e. frame),
+   which exists on only one screen; therefore the event won't be
+   reported multiple times even if there are multiple devices on
+   the same physical display.  This is an implementational detail
+   specific to X consoles (e.g. under NeXTstep or Windows, this
+   could be different, and input would come directly from the console).
