Something like that might be helpful. However, I've been reluctant to do 
this myself, partly because I think it would make for more work for me 
(not less), and partly due to licensing concerns: the GitHub platform 
(as opposed to Git itself) is closed source, and tzdb development should 
require only portable tools that are freely available so I would rather 
not rely on GitHub-specific automation.

One possibility is to do build automation on some platform that is not 
closed-source; I don't know whether BitBucket has similar issues. At any 
rate I wouldn't let any of this stop you; if you can easily build 
something downstream on BitBucket, that would be a useful resource I'd 
think, even if it's not part of tzdb proper.
