Specific options: 
       --dev path  use path as drive address. Default: /dev/cdrw
       --what path use path as address of the directory which shall
                   be copied into an ISO 9660 filesystem on media.
       --any_media allow non re-usable MMC media, like CD-R or DVD+R.
                   Allow paths to non-existing files, but disallow paths
                   to existing regular files.
       --priv_cmd 'command [arg [arg ...]]'
                   With drive operations execute xorriso as argument
                   of the given command (e.g. pfexec, sudo) with the
                   optionally given arguments: command arg arg xorriso ...
                   Command and arguments must be single words.
Overview:
       Test burning to re-usable media CD-RW, DVD-RW, DVD-RAM, DVD+RW, BD-RE.
       By default, one-time usable media will be rejected deliberately.
