  "why_use_this": "zlib is a foundational dependency for countless build chains and runtime environments; most systems have it, but Homebrew\u0027s keg-only formula lets you explicitly link against a specific version if macOS\u0027s bundled zlib is insufficient or outdated. Use this when you need reliable deflate/inflate support for custom tools or when building projects that require an exact zlib version."
