Ah, okay :-)

Interesting... what other sorts of indexing does it do? Might be interesting for
using in the Indexer I'm working on. Would it provide a lot of functionality
that ZCatalog uses or would I be better off using the BTrees stuff that Jim and
other worked on for ZCAtalog?

I'm nto gonna make any comments about Netscape browsers ;-) I guess the bit
which bugs me is it's something else I have to install. Are there any plans to
make ZODB (and Zope ;-) releases that include the necessary version of BerkleyDB
in the same way that they currently include the necessary version of Python?
