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.

The Service class implements the DSL methods used in a formula's service block and stores related instance variables. Most of these methods also return the related instance variable when no argument is provided.
