Yes, of the two they are the simpler to understand.

Andrew packaged it in his distribution so I assumed it was actually used
for something. However, seeing the fact that nobody cites it anywhere, it
may be there just for completeness' sake.

The state of non-dox is such that I wonder even at to what exactly Catalog
_does_, though I admit I haven't dug very deep! :-)

Well, we have
http://lists.zope.org/pipermail/zope-dev/2000-May/004646.html and the
HOWTO at http://www.zope.org/Members/kelcmab3/catalog_out_of_zope -- I'm
just not sure they correspond to the current codebase in Catalog. I'll sit
around this afternoon looking at the code.

Take care,
