Due to an unfortunate name of the class. I simply didn't consider this
situation when I picked that name.

First you have to understand that jython-21a3.class is both a class file
and a .jar file and for this purpose you have to see it only as a jar
file.

You start by adding jython-21a3.class to your CLASSPATH or through your
own class loader.

 classpath=d:\java\jdk1.4\jre\lib\rt.jar;jython-21a3.class

The you can start the installer with:

    public static void main(String[] args) {
        new net.sourceforge.liftoff.installer.Install2(args);
    }

I'll refer you to the liftoff sources for the details of programmaticly
choosing a destination dir and which bundles to install:
