On a historical note, I've discovered the origin of
this split.  It's a suggestion from Robert Elz, archived at
<http://mm.icann.org/pipermail/tz/1992-November/000227.html>: "perhaps
separate the rules from the code in the ftp archives, the rules change
more frequently ...".  In fact, since then there have been about 85%
as many code releases as data releases (~160 code and ~190 data), so
that part of the rationale hasn't fared so well.  The other part of the
rationale is about users with their own code, of which there are some,
but the occasional necessary feature added to zic poses difficulties
for this mode of use.
