Has there been any look into using public CI systems? I know you can use Travis (Linux and OSX) and Appveyor (Windows) with git/Github/Gitlab, don't know about mercurial though. I know that there's been significant discussion about mercurial/git, but I don't know if people have taken public CI systems into account.

I've made a sample repo on Github (https://github.com/stephengroat/chirp) and made Travis CI (https://travis-ci.org/stephengroat/chirp) and Appveyor (https://ci.appveyor.com/project/stephengroat/chirp) that people can take a look at. Appveyor isn't 100%, but I'm close. These builds also trigger for Pull Requests, just make a sample PR against the repo to see. Auto deployment to Github Releases/etc. is also easy to do as well.

Let me know if people are interested in this addition and thanks for all the hard work on the project!
