    `brew install llnode` does not link the plugin to LLDB PlugIns dir.

    To load this plugin in LLDB, one will need to either

    * Type `plugin load #{opt_prefix}/llnode.dylib` on each run of lldb
    * Install plugin into PlugIns dir manually:

        mkdir -p ~/Library/Application\\ Support/LLDB/PlugIns
        ln -sf #{opt_prefix}/llnode.dylib \\
            ~/Library/Application\\ Support/LLDB/PlugIns/
    EOS
  end

  test do
    lldb_out = pipe_output "lldb", <<-EOS.undent
      plugin load #{opt_prefix}/llnode.dylib
      help v8
      quit
    EOS
    assert_match /v8 bt/, lldb_out
  end
end
