Re: [tz] [PATCH] mention the github repo in the main tz page

Thanks, I think I'll add something a bit more cautionary, along the following lines: An <a href="https://github.com/eggert/tz">unofficial development repository</a> of the code and data is available in <a href="http://git-scm.com/">Git</a> form; be careful, as this repository is less well tested and probably contains more errors than the official version.
