Perhaps one might check if "git" was installed.
I'm sure Robert could do that, but I assume he doesn't want to bother. I don't know which version-control system he used (if any) when he maintained tzdata (2011l through 2012c). Arthur David Olson used SCCS before that. tzdb has always been distributed as a tarball that requires only standard POSIX utilities like 'make', 'awk' and a C compiler to build, and there are no plans to change this. However, maintainers can be expected to have a better set of development tools than what POSIX requires. Nowadays a good repository system is invaluable for any nontrivial software project, and I didn't have any qualms about using Git for current maintenance, as it's by far the most-popular such system and it's free. If you don't want to use Git that's fine; we'll take plain POSIX 'diff -u' patches instead.
