Oh, you should have a compositor first. This tool is only used to
redirecting data on the wire.

Suppose you have a compositor which runs on wayland-0. You can run
(Supposed environment variable WAYLAND_DISPLAY=wayland-0)
$ ./wayland-tracer -S wayland-1

Then if you run under another terminal
$ WAYLAND_DISPLAY=wayland-1 weston-flower

You'll see weston-flower and in the compositor and the communication
dumped.

You also got to have a running compositor. But this reminds me to check
whether the connection is successful.
