#  To run this script you will need to have the following:
#	1) a Java VM installed (however, it will handle a lack of Java nicely).
#	2) a Java-style properties file having the same name as this script 
#		with the suffix .lax.  If this script is appended to the
#		self-extractor, it will look for the properties file in the
#		directory specified by $seLaxPath; otherwise, it will look in
#		the same directory that this script is in.
#	3) a Java program in the file "lax.jar".
#
#  The .lax property file must contain at least the following properties:
#	1)  lax.class.path  classpath (do not include the environment variable $CLASSPATH )
#	2)  lax.nl.java.launcher.main.class  (main class of LaunchAnywhere Executable)
