+-   `disable_stop_instance` (boolean) - Packer normally stops the build instance
+    after all provisioners have run. For Windows instances, it is sometimes
+    desirable to [run Sysprep](http://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/ami-create-standard.html)
+    which will stop the instance for you. If this is set to true, Packer *will not*
+    stop the instance and will wait for you to stop it manually. You can do this
