## Overview

This repository is a deprecated legacy Homebrew project, not an active runtime package. Its README says the former formulae and packages moved to homebrew-core, while the package manager moved to brew. No source excerpts are available, so the graph captures only these documented destinations and does not infer runtime behavior.

Main entry points: [`README.md`](https://github.com/homebrew/legacy-homebrew/blob/master/README.md) (Legacy Homebrew)
