  [/Overwrite:{Yes | No | Append}]
        Determines whether the file specified in /DestinationImage
        should be overwritten if an existing file with that name
        already exists. No means WDS will error if a file with the
        same name exists.  Append means that if a WIM file with the
        same name already exists, the generated image should be
        appended as a new image within the existing WIM file.  The
        default is No.

  [/UnattendFilePath:]
        Sets the full path and name to the unattend file for the
        capture image (WDSCapture.inf).
