[Zope] Defining classes in scripts in Zope 2.7, examples are broken

[Jeff Kowalczyk]

What is the new convention for creating classes in scripts? Is
it disallowed now?

The examples (File Library, Guest Book) define exception
classes in their add/upload scripts, which results in an error on
Zope2.7b3 Win32.

Thanks.
