	vnc kill=session
 INPUTS:
	session		vnc session number
 PROCEDURE:
 >	No argument displays syntax information
 >	Arg 'list' displays all sessions stored in the file ~/.vnc/vnc.log
 >	If argument 'start' is specified then the program vncserver is called to
	start a new vnc session. The session number is stored in the file
	~/.vnc/vnc.log
 >	If argument 'kill' is specified (without a session number) then an
	attempt is made to kill every vnc session listed in the file
	~/.vnc/vnc.log. When a session is killed successfully the matching
	entry in ~/.vnc/vnc.log is removed.
 >	If 'kill=session' is specified as argument the vnc session
	with the specified number is killed, and removed from ~/.vnc/vnc.log
 >	When a session is killed several files are automatically deleted
	(# is a one-digit integer)
	- a *.pid file: ~/.vnc/cass180.ucsd.edu:#.pid
	- a link to an X-server: /tmp/.X11-unix/X#
	- a lock file /tmp/X#-lock
 >	Not automatically deleted is a log file:
	- ~/.vnc/cass180.ucsd.edu:#.log
	This file can get quite big (Gigabytes) and is explicitly deleted
	by this script.
