The command which is executed whenever cdrestore needs to request a new media for multi\-disk backups. This command (or script) should prompt the user and return after the device is ready again. The command receives one argument, which is the device name passed with \fB\-d\fR. This can be used to issue commands to the device like ejecting the media.
