This rules file tells udev to create symlinks for input devices
(keyboard and mouse, at this moment) separated by seat, so it could
be easier for one to get quickly the devpath of a given input
device attached to a given seat.
Example: the keyboard attached to seat-foo will receive a symlink
with path /dev/input/by-seat/seat-foo.kbd-event
It can be very handful specially for Xephyr-based multiseat setups,
where input devpaths must be passed via command line options
like -keybd and -mouse.
