I've updated the tz-history-scripts to include kre's most recent release and to generate either git or hg repositories. These can obviously be useful to the current (or future) maintainer, but from reading patches on the list it's clear that others have used things like git or RCS (for example, kre and eggert) even while ado was using SCCS. So these scripts (or more likely, the example repos) could be useful to future contributors. The scripts are here: https://github.com/lyda/tz-history-scripts Example repositories are here: Git version: https://github.com/lyda/tz Hg version: https://bitbucket.org/lyda/tz A note on the example repositories, don't send pull requests to them. And I wouldn't suggest using github or bitbucket's forking feature. First, I'm not the maintainer. If kre wants to make his own repo and publish that, he'll let folks know. Secondly, when I get new data I will at times blow them away and recreate them. If you clone from them (and please do, it's what they are there for), update your .git/config or your .hg/hgrc to remove mention of where you cloned them from to avoid issues when I do reset them. They're there as an example and as a convenience for people who don't want to use the scripts and download all the data. And it's an understandable thing to avoid: The total size of all the tarballs is: 46M The mercurial repo is: 3.2M The git repo is: 3.0M Clearly a DVCS is better at compressing files than tar and gzip! :) Kevin
