                        System model identifier to use (otherwise this
                        machine's model is used). This can be specified
                        multiple times to download multiple models in a single
                        run.
  -i, --install         After the installer is downloaded, perform the install
                        automatically. Can be used on Windows only.

                        Base path where the installer files will be extracted
                        into a folder named after the product, ie.
                        'BootCamp-041-1234'. Uses the current directory if
                        this option is omitted.
  -k, --keep-files      Keep the files that were downloaded/extracted. Useful
                        only with the '--install' option on Windows.
  -p PRODUCT_ID, --product-id=PRODUCT_ID
                        Specify an exact product ID to download (ie.
                        '031-0787'), currently useful only for cases where a
                        model has multiple BootCamp ESDs available and is not
                        downloading the desired version according to the post
                        date.
