    Metadata details:

  url "h
    
  def install
    ENV.append_to_cflags "-I."
    ENV.append "CXXFLAGS", "-std=c++11"
    linker_flags = %w[lookup2.o -lcrypto -lplist-2.0 -lxml2]
    linker_flags += %w[-framework CoreFoundation -framework Security] if OS.mac?

    system "make", "lookup2.o"
    system "make", "ldid", "LDLIBS=#{linker_flags.join(" ")}"

    bin.install "ldid"
    bin.install_symlink "ldid" => "ldid2"
  end
