Pd is a client-server system connected by a socket. the client sends to
the server using the "pd" proc in Tcl, in the same format as [netsend].
The server sends to the client Tcl commands using sys_gui(), and the
client calls "eval" on them.

sys_gui() takes a single string argument. sys_vgui() is a combination of
sprintf() with sys_gui(), so it takes the same arguments as printf(),
which are (const char *format, ...) where format is a %-string.
