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 ensures that a supported symbol (head, stable, homepage) is used when the livecheck url` is identical to one of these formula URLs.
