Indeed. May be in the future we could recreate a simple compliant spec driven method by interpreting the
existing configuration trees but this requires some work.

I mean going over the configurations with dependencies to recreate the tree structure but with versions.
May be this is not needed because for versions we do not need dependencies so just group them per configurations.

Hi,

I would be happy to blend Snapshotcello into Metacello.
