anchor.diff:    # backing providers for Vagrant. These expose provider-specific options.
     # Example for VirtualBox:
     #
  -  # config.vm.provider :virtualbox do |vb|
  +  # config.vm.provider "virtualbox" do |vb|
     #   # Don't boot with headless mode
     #   vb.gui = true
     #
  
positive.code:   # path, and data_bags path (all relative to this Vagrantfile), and adding
    # some recipes and/or roles.
    #
    # config.vm.provision :chef_solo do |chef|
    #   chef.cookbooks_path = "../my-recipes/cookbooks"
    #   chef.roles_path = "../my-recipes/roles"
    #   chef.data_bags_path = "../my-recipes/data_bags"
  
negative.code:   # Create a forwarded port mapping which allows access to a specific port
    # within the machine from a port on the host machine. In the example below,
    # accessing "localhost:8080" will access port 80 on the guest machine.
    # config.vm.network "forwarded_port", guest: 80, host: 8080
  
    # Create a private network, which allows host-only access to the machine
    # using a specific IP.
    # config.vm.network "private_network", ip: "192.168.33.10"
  
    # Create a public network, which generally matched to bridged network.
    # Bridged networks make the machine appear as another physical device on
    # your network.
    # config.vm.network "public_network"
  
    # If true, then any SSH connections made will enable agent forwarding.
    # Default value: false
