[Zope] [zope 2.7-2.8] Howt to alow import module in Python script

Hi, As far as I know, if I want to use/import a module (let's say urllib*) in a Python Script (the restricted ones), I have to use external methods and then use it in the Python script. I remember I saw in a zope related Mailing List (CPS, Plone, Zope...) I cant list somewhere the modules I want to be loadable from restricted Python script. Would you remind me the place I could do it please? Thank you. I mostly need urllib, ftplib, re, HTMLParser,...
