module: win_robocopy
version_added: "2.2"
short_description: Synchronizes the contents of two directories using Robocopy.
description:
    - Synchronizes the contents of two directories on the remote machine. Under the hood this just calls out to RoboCopy, since that should be available on most modern Windows Systems.
options:
  src:
    description:
      - Source file/directory to sync.
    required: true
  dest:
    description:
      - Destination file/directory to sync (Will receive contents of src).
    required: true
  recurse:
    description:
      - Includes all subdirectories (Toggles the `/e` flag to RoboCopy). If "flags" is set, this will be ignored.
    choices:
      - true
      - false
    defaults: false
    required: false
  purge:
    description:
      - Deletes any files/directories found in the destination that do not exist in the source (Toggles the `/purge` flag to RoboCopy). If "flags" is set, this will be ignored.
    choices:
      - true
      - false
    defaults: false
    required: false
  flags:
    description:
      - Directly supply Robocopy flags. If set, purge and recurse will be ignored.
    default: None
    required: false
author: Corwin Brown (@blakfeld)
notes:
    - This is not a complete port of the "synchronize" module. Unlike the "synchronize" module this only performs the sync/copy on the remote machine, not from the master to the remote machine.
    - This module does not currently support all Robocopy flags.
    - Works on Windows 7, Windows 8, Windows Server 2k8, and Windows Server 2k12
