No, no, no. This is a very simple problem. No splitting of files is
allowed. These are all files that will fit within one CD.

K3b doesn't seem to work, and the multicd seems to still use commands
from 2001. It refers to the CD burner as a scsi device. But, I can
probably hack multicd. I just want a CD I can put in the CD drive and
browse the files so that they are in the same directory structure as
original.
