[Zope] Namespace for PythonScript

[Hong Yuan]

Hello,

If a PythonScript is called from a Page Template, how can it access the 
variables defined using:
   <tal:define="global ..." />
in the calling script?

Of course, one can pass the variables to the PythonScript explicitly as 
parameters, but is there any other way to let the PythonScript to easily 
access the name space of its calling page template?
