Using JYTHON inside ANT : access os module -> "ImportError: no module named javaos"

I ran into that one as well.  I think that you have to have the PYTHON 
path or classpath properly setup to reference them.  I did not really 
need anything from python, so I just used java routines for everything 
as I was generating a manifest file.

Tip: Due to the forced indent from python, I moved the script to a 
separate file.  This way the code can look like a normal jython/python 
script.
