semi-automatic text mapping to real libburn addresses. See cdrskin/README,
"Pseudo-SCSI Adresses".
If you need to foist cdrskin under a frontend then you may be lucky and
both ideas of an address coincide. Especially if the frontend has the
decency to ask its "cdrecord" via option -scanbus for a list of drives.
If not, look into the error protocol of the frontend, look at the output
of a run of cdrskin --devices and give cdrskin the necessary hint.
