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,
- This is not a complete port of the M(synchronize) module. Unlike the M(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
