[Zope] Python calling files from ancestor directories?

[Alec Munro]

Hi there,
Any idea how I can use Python to call a file two directories up?
So if my python script is at:
/root/blah/cgi/someScript

And I want it to return the file:
/root/nah/someFile

I haven't figured out how to do this yet, any ideas?
