I've released the second version of this tool which I consider stable.
It is now called ``zodbupdate``.
The major shift is that it allows to provide a pre-defined set of
class-renaming rules and can rewrite pickles in ZODBs without having the
actual code activated in the Python interpreter. It does this by dis-
and re-assembling the pickles.
I consider the ZODB migration code project to be finished with this.
@Martijn: Did we have a place somewhere in the documentation that needs
to be updated to reference this?
Cheers,
Christian
