Looking closer at a recent version of Archetypes, I realize that "interfaces.py"
is a legacy module used to define Zope2 interfaces, while the fodler "interface"
stores Zope3 interfaces.

Lesson: Use an "interfaces" folder for Zope3 interfaces; in the rare case you
need to keep "interfaces.py" for Zope2 interfaces, use an "interface" folder.

Peace,
George
