Hi Chefs,

I recently merged a change to add `cookstyle` to ChefDK. The latest build in  
the current channel contains this change and it will be included in the next  
stable release.

### What’s cookstyle?

`cookstyle` is a linting tool based on rubocop. We created `cookstyle`  
to address two issues with rubocop:

1. New releases of rubocop usually contain new style rules, which causes  
most projects to fail style checks after updating rubocop.
2. rubocop’s default configuration enables many checks which are not  
appropriate for cookbook development.

`cookstyle` fixes these by pinning to an exact version of rubocop and  
replacing the default configuration with one that we’ve customized to  
work better for cookbook development. When a new version of rubocop is  
released, we run an automated process to disable new style rules in the  
default configuration, which allows you to update with confidence.

In the future, we plan to version cookstyle’s ruleset so we can deliver  
updates but give you control over when changes take place.

If you have any suggestions for changes to the default ruleset in  
`cookstyle`, please [create a pull request](https://github.com/chef/cookstyle).
