[Pharo-users] Monticello - break up a package

Following up on my quest to get SandstoneDb to run on Pharo 2.0. Ramon asked me to break out my changes to the file store into another package, so that it is possible to just use the appropriate package for different Smalltalk versions. Now, how do I best do that? When I tried it before, I got a new package with no acestors, but the same content still in the "base" package. Thank you for your help so far. Kind regards, Ingo
