 cdrskin does not contain any bytes copied from cdrecord's sources. Many bytes
 have been copied from the message output of cdrecord runs, though. I am
 thankful to Joerg Schilling for every single one of them.

-Actually i, Thomas Schmitt, am a devoted user of cdrecord via my project
-scdbackup which still runs a bit better with cdrecord than with cdrskin. TAO.
 I have the hope that Joerg feels more flattered than annoyed by cdrskin.

 Many thanks to Andy Polyakov for his dvd+rw-tools
