Overview

This class is part of a private API. This class may only be used in the Homebrew/brew repository. Third parties should avoid using this class if possible, as it may be removed or changed without warning.

This cop makes sure that the generate_completions_from_executable DSL is used with only a single, combined call for all shells.
