I'm the baretorrent developer.

You did not, but I'm up to a point where this is becoming very difficult to manage without unit testing, and it slows down and reduces the quality of my releases. I'm actively using baretorrent on debian and developing it on windows, but my tests on osx are limited. It also became a complex system much quicker than I anticipated (like most systems do).

Automated tests will come soon.
