The problem, apparently, raises it's head in the 3rd line of the 
traceback. The code there reads:

def call_object(object, args, request):
    result=apply(object,args) # Type s<cr> to step into published object.
    return result

So, I'm not sending the correct arguments to Zope. This is my first 
External Script in years (and I'd only written a couple before). So, 
please help me with this. The script is below in its (short) entirety. 
It works just fine from the command prompt. The idea is explained in the 
comments. Please help me understand how to pass it arguments.
TIA,
beno
