Looks like my 'phone' reply only went to Paul ...
http://hg.lsces.org.uk/hg/tzdata/tags was my attempt to produce a
'diffable' version of the data tarballs. need to add in the resent
releases, which is the easy bit, but I would like to go back down the
list as well and tag the earlier releases.
The thought a couple of years back however was to simply build a short
repository from the tagballs on top of the pre 1996 data from the repo
build. But it is all probably just of academic interest now so is there
actually any point.
