run_pylint() 

To use this you need to have pylint (and astroid, which is a dependency of pylint) installed:
pip install pylint

And then you should be able to just run hylint.py as if it were pylint to check hy sources.

For anyone wondering how to make this work, looks like astroid builder now uses _parse instead of parse.
