This is the implementation of [RFC-087](https://github.com/chef-boneyard/chef-rfc/blob/master/rfc087-distro-sugar-helpers.md)
although some of the specifics have been iterated on and changed.

The documentation will be in the [README.md](https://github.com/chef/chef/tree/master/chef-utils/README.md) once this is merged.

as well.
