wctl
----

The wctl rc script can be run from a Plan 9 system to serve a wctl
service using an existing wsys service, see wsys(4).

Eg:
	wsys='#Z/tmp/ns.username.:0/wsys'
	wctl=`{wctl $wsys}
	window games/catclock


devdraw.9p
----------

9p-srv.c is a p9p's devdraw(1) version which uses wsys(4) through
9pclient(2). To install it:
	cp 9p-srv.c $PLAN9/src/cmd/devdraw
	cd $PLAN9/src/cmd/devdraw
	9c 9p-srv.c && 9l -o devdraw.9p 9p-srv.o
	cp devdraw.9p $PLAN9/bin

It will connect to the window system with address $WSYS.  Some files
(snarf and the draw directory) are not served by rio, although they
are served by wsys(4).  These files are expected to be found on the
file server with address $DEV.

Eg:
	# From rio (for just one window, created from rio):
	; mount $wsys /n/w new
	; bind -a '#i' /n/w
	; bind /dev/snarf /n/w # if needed
	; aux/listen1 -t 'tcp!*!12345' /bin/exportfs -r /n/w

	# From rio (create new windows with new commands):
	; aux/listen1 -t 'tcp!*!12345' /bin/exportfs -S $wsys
	; aux/listen1 -t 'tcp!*!12346' /bin/exportfs -r /dev

	# From unix:
	$ DEVDRAW=devdraw.9p export DEVDRAW
	$ WSYS='tcp!127.0.0.1!12345' export WSYS
	$ DEV='tcp!127.0.0.1!12346' export DEV # if needed
	$ 9term

	# Alternatively, if using wsys instead of rio:
	$ WSYS='unix!'/tmp/ns.$USER.$DISPLAY/wsys export WSYS
