So you meant depended on.  You have a Zope 3 instance part that  
depends on
a zope 3 installation which is a checkout.  Now, when you install a  
part, any
part it references will be included in the part list.
The zope3checkout does an svn up whenever it runs.

OK, I agree. So we'll either need another command, or an option on  
the install command (or maybe a buildout section option).
