yamllint

#!/usr/bin/env python

'''
Usage: yamllint /path/to/lint

Namely used for salt, but recursively checks a directory for files. For each file that ends with "sls" - check to ensure it can load using YAML. Print any files that have exceptions.

Great as a pre-commit hook to any github project working on YAML-based files.
