"""gbjoin - launch a windowed Game Boy and plug its link port into a running
gbhub, so it joins the shared network (gets a DHCP lease, can talk to the other
Game Boys and the internet). Start the hub first, in its own terminal:
sudo tools/gbhub --daemon
Then, one per terminal:
tools/gbjoin # sixel + Game Boy chrome (default)
tools/gbjoin --palette green # any sl0pboy display options pass through
No root needed (the hub opens the link socket world-connectable). On the Game
Boy: SELECT toggles the on-screen keyboard, then type e.g. ping 10.0.0.3.
