[Zope] How to get context from Zope 2

[Baiju M]

Hi,
    How can I get the context (say, root folder) within a function
called by a scheduler.  I am using tgscheduler to call a function
at particular interval: http://code.google.com/p/tgscheduler/

How can I get the root folder (context) from this function ?


Regards,
