Thank you for the contribution!

I manually tested by pulling your fork, looks good. I just left one small comment.

If possible, can you please add some tests here - https://github.com/ReviewNB/treon/blob/master/tests/test_treon.py ?

[garrison]

I added a test. It assumes that py.test is invoked from the base of the repository. (I'll note that the filter_results tests have the same paths written without the tests/ in front; however, they work regardless of where py.test is invoked from, as they do not actually look at the filesystem.)

[garrison]

I thought of a way to make py.test work from any directory and pushed the change.

Thanks @garrison

I've merged this PR & released a new version (0.1.4). Please give this a try when you can.

I also added some more tests following your pattern.

Thanks again for your contribution. Cheers!
