    Once you've started lightsd with launchctl load (see below), you can start
    poking around with lightsc.py:

      `lightsd --prefix`/share/lightsd/examples/lightsc.py
    EOS
  end

  head do
    url "https://github.com/lopter/lightsd.git"
  end

  devel do
    url "file:///Users/louis/projs/lightsd", :using => :hg
    version "1.1.0"
  end

  test do
    Dir.mktmpdir("lightsd-test") do |dir|
      args = %W[
        -l ::1:0
        -l 127.0.0.1:0
        -c #{dir}/lightsd.cmd
        -h
      ]
      system "#{bin}/lightsd", *args
    end
  end
