The YY server is the program which connects to an X display from an
application program (the client). It acts on the commands of the
client, and conveys input to the display back to the client, after a
filtering stage. Because it works over internet sockets, it can run
on any machine on the local net, and so need not compete for CPU
cycles with . can use any X windows display for its
output as long as the machine running the server has permision to use
that display. Thus up to three machines can be involved in the process
of producing a picture. The server currently runs on sun-3 and sun-4
machines, and may have difficulty communicating with machines which
use a different byte order.
