anchor.diff:  result of the Hyper-V builder is a directory containing all the files
   necessary to run the virtual machine portably.
   
  -## Basic Example
  -
  -Here is a basic example. This example is not functional. It will start the OS
  -installer but then fail because we don't provide the preseed file for Ubuntu
  -to self-install. Still, the example serves to show the basic configuration:
  +## Basic Examples

  +Here are some basic examples. Neither example would really do anything more
  +than producing a copy of the source virtual machine. However, the examples
  +could be used as a starting point for more advanced templates.
   
   Import from folder:
   
   ``` json

     "type": "hyperv-vmcx",
  -  "clone_from_vmcx_path": "c:\\virtual machines\\ubuntu-12.04.5-server-amd64",

     "ssh_password": "packer",
     "shutdown_command": "echo 'packer' | sudo -S shutdown -P now"
  
positive.code:     Packer to wait for 1 minute 30 seconds before typing the boot command.
      The default duration is "10s" (10 seconds).
  
  -   `clone_all_snapshots` (boolean) - If set to `true` all snapshots will be
      cloned when the machine is cloned.
  
  -   `clone_from_snapshot_name` (string) - The name of the snapshot to clone
      from.
  
  -   `cpu` (number) - The number of CPUs the virtual machine should use. If
      this isn't specified, the default is 1 CPU.

  ### Required for virtual machine import:
  
  -   `clone_from_vmcx_path` (string) - The path to a directory containing a
      previously exported virtual machine. The exported machine will be used
      as the source for new VM.
  
  
  ### Required for virtual machine clone:
  
  -   `clone_from_vm_name` (string) - The name of the VM to clone from. Ideally
      the machine to clone from should be shutdown.
  
  ### Optional:
