Tab-delimited ?

A few suggestions:

It would be useful to either have 3 scripts or 3
commandline options to the script that

1) download the data
2) create the dpd.db
3) install the dpd.db as drugs.db (and safekeep the original)

I would improve drugs.orig to $timestamp-drugs.db.bak

fully solve to select from more-fully normalized (but
non-unique) Canadian data into the FreeDiams schema.

Just nitpicking: uniqueness is only a function of
normalization where it removes redundancy. Since the
non-unique records carry *different* information about the
same drug they don't automatically fall fould of
normalization (but they do because - AFAICT - they don't
ONLY carry non-redundant information plus a foreign key).

Well done !

This could well get included with FreeDiams as additional
helper scripts even if not otherwise integrated with the
