I really can't decide on this one. It really looks like ado keeps the
whole thing in one directory and has maintenance scripts that generate
What I'm leaning towards is starting with them all in one dir and
then, withe the initial 1993 release moving to having them in tzcode
It might make the migration of the sccs history a bit harder, but I
think it will better reflect what is happening.

There will be a separate commit for each tzdata and each tzcode release.

Absolutely not - it would be insane to get rid of tarballs (or some
package format - the initial releases were shar and patch so it's
changed over time). I just want the history of the project
maintained. First because I like history but also because having the
complete history in one easy to view place might be of assistance to
ado and eggert (that's why I've made sure to reference sources in each
Part of that history is the tarballs (and shars and patches)
themselves. So they should definitely be maintained. And obviously
they're very useful for end-users for future releases. This is just
for "digital historians" (or whatever such a field will be called) and
a possible base for future maintainers of the code/data.

I have never really used Windows so I was unaware of this issue. I
actually started using DVCS with hg, but trends really seem to be
favouring git over hg and bzr from what I've been reading. I don't
want to start a VCS war though so I can look at providing both a git
and hg repo (I think the migration from git to hg is pretty simple).
I could put both up onto bitbucket.org - they now support both
formats. And a Windows version would likely be very useful for legal
assistance reasons - I suspect lawyers and judges might not be Unix
I'll offer this suggestion however. I do all my work on an OS X box.
While OS X has unix roots its fs is not case sensitive. At times
that's an issue. So to avoid that I generally use VirtualBox and some
handy Linux distro (lately Debian or Ubuntu since my employer uses
those) to do actual work on unix-related projects. Machines are fast
enough these days that it's as fast as I need it to be.
