Hi - I've been looking at zope.generations
(http://pypi.python.org/pypi/zope.generations) - "Generations are a way
of updating objects in the database when the application schema

My interest is for a standalone ZODB database. The example given on that
page seems to presume that generations will only ever be used within
Zope. It's a shame because it looks like a good facility.

My questions are : 

   * Is zope.generations able to be used on a standalone ZODB database ?
   * Are there other, similar, facilities which would track change to
   application classes (or at least accept notifications of them) and
   automatically 'fixup' the corresponding classes already in the
   database ?
