  depends_on "go" => :build

  def install
    ENV["GOPATH"] = buildpath
    (buildpath/"src/github.com/quantumew/jamal").install buildpath.children
    cd "src/github.com/quantumew/jamal" do
      system "go", "get"
      system "go", "build", "-o", "#{bin}/jamal"
    end
  end

  test do
    system bin/"jamal", "--help"
  end
end

I wrote this, then tried to submit it to the master list but got this error:

% brew audit --new-formula jamal
jamal:
  * C: 15: col 7: Do not use `go get`. Please ask upstream to implement Go vendoring
  * GitHub repository not notable enough (<30 forks, <30 watchers and <75 stars)
Error: 3 problems in 1 formula detected

The first one I could probably work with Andy to fix, the last one not so much. 😢
