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.

A Tap is used to extend the formulae provided by Homebrew core. Usually, it's synced with a remote Git repository. And it's likely a GitHub repository with the name of user/homebrew-repository. In such cases, user/repository will be used as the #name of this Tap, where #user represents the GitHub username and #repository represents the repository name without the leading homebrew-.
