[Zope] user defined libraries

Silly question: How does one use use one's own library of Python classes (imported using an import statement) inside a zope'd python script? Right now its giving me an error message whenever I try to do such. -- Matt -------------------------------------- Nu sculon herigean heovonrices Weard Meotodes mighte ond His modgethanc Now we must praise the Kingdom of Heaven's Sovereign, The Measurer's power and his completed design --First two lines, Caedmon's Hymn ---------------------------------------
