What is Travis CI?
https://travis-ci.org/ is pure awesome! Travis is a free and open
source CI platform that hooks directly into https://github.com/. It's
extremely easy to configure, tests on every major 5.10+ Perl version,
and will notify you of test results, either through email or IRC. (Yes,
a bot will jump into an IRC room, tell you the results, and bounce. How
cool is that?!)

If you're not familiar with CI platforms, this is your chance to get
your feet wet. CI stands for
http://en.wikipedia.org/wiki/Continuous_integration. This kind of
testing is designed around testing your code every time you
commitsolpush a change. In this case, this is a hook into Git via
GitHub to make sure that any change you make is going to pass tests.

Perl is already a "test-heavy" community. What does this add?
This is true. Travis CI has a much more profound use with languages
without a deep-seated testing platform like Perl's tsol* directory (and
its hooks with CPAN).
