ACK. Well documented and understood.

ACK. But - given a 'whole cloth' approach, it is a (relatively)
trivial exercise to accomplish the same functionality by any of
several means.

I've just compiled the pure-db libs, and am looking at others.

I want to deliver a 'set' of structured objects - each optimized
for the type of data stored, such as:

IP:white/black,

REGEXP:white/black,

UID:PWD(s),

UID [Domain]:prefs

...to Exim that it already knows how to read, but not have to
carry any of the related DJB 'specialties' with it.

Daemontools, for example, which seems to ship with all his code,
may even be at work in his 'fridge. That critter is a RBK to
hunt down, dis-entangle, and rm.

ACK. It is a math/logic/mapping exercise, and that is his forte.
