The changes to make Zope 3 use ZODB 3 have been checked in.

We currently have both ZODB abd zodb packages, which will
break windows checkouts.  We are going to fix this by getting rid
of the zodb package. We'll send another note to let everyone know
when this is done.

If you have any code that imports from zodb, you will need to change
it to import from ZODB instead.

Update Procedure
----------------

Use this procedure to update the software and convert databases:

1. Back up your databases (Data.fs* files).

2. Update the software using "cvs up -dP".

3. Re-build compiled modules:

    $ python2.3 setup.py build_ext -i

4. Run the conversion script for each FileStorage:

    $ PYTHONPATH=src python2.3 src/ZODB/zodb4/main.py Data.fs

This will move the existing ZODB 4 database to a backup file (the .fs
extension will be changed to .fs4; if the main file doesn't use the
.fs extension, .fs4 will simply be appended).
