# 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)

# this is not an installer but a separate launcher.
# USERENV is just a flag passed from use.sh.
