A General Guardfile to sit at the head of a Chef Repository. (Caveat: Nearly all of our cookbooks are developed in-house, and all internal cookbooks are prefixed with "devops_", which explains why we limit paths the way we do. We also have an internal cookbook named devops which adds another cog into the mix.)
