[Zope] Zope Products without Sources

Hello, on the filesystem we see files ending with .py and with .pyc - what's happening inside the ZODB? If I want to sell a Zope Product, can I savely delete all sources (.py)? How to shut the backdoor inside the ZODB? Can we somehow remove the ZMI (the sources or better all the functionality of the Zope Management Interface)? -- Best Regards, Marc Roland AICAT CA Technologies GmbH Dipl.-Ing.(FH) System Consultant Friedrich-Karl-Str. 101-103 Fon:+49/(0)221/971445-0 Fax:-5 Germany-50735 Koeln (Niehl)
