Running brew audit --strict --online on a formula with a GitHub
homepage/url would crash if HOMEBREW_NO_GITHUB_API is set because
GitHub.repository returns `nil` and the audit code assumes it always
returns a hash.

This is the (partially) documented public API for Homebrew.
The main class you should look at is the {Formula} class (and classes linked from there). That's the class that's used to create Homebrew formulae (i.e. package descriptions). Assume anything else you stumble upon is private.
