GitHubReleaseDownloadStrategy downloads tarballs from GitHub Release assets.
To use it, add ":using => GitHubReleaseDownloadStrategy" to the URL section
of your formula. This download strategy uses GitHub access tokens (in the
environment variables GITHUB_TOKEN) to sign the request.
This strategy is suitable for corporate use just like S3DownloadStrategy,
because it lets you use a private GttHub repository for internal distribution.
It works with public one, but in that case simply use CurlDownloadStrategy.
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.
