Ruby on Rails

Thanks Walter, very clear and useful, it looks right for me - but two
things.

1) Why does it create the user stuff in the vv migration/model - I dont
have users in this app, should I delete those attributes or just not
worry about them, and it'll just work (tm).

2) It seems to be more aimed at REVERTING to previous versions rather
than querying them - to explain, in my app I'd like to keep a history of
price tiers of apple store apps, so each day an App.tier might equal a
different value, I might like to print them all out over time or chart
them or more likely find an apps highest or lowest tier historically -
is that easy/doable with VV?

It looks very powerful.

Thanks
