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

blank=deformat_sequential_quickest is faster but might yield DAO-only media.
DVD+R
From the view of cdrskin they behave much like DVD-R. Each track gets wrapped
into an own session, though.

The only restriction towards CD-R[W] is the lack of support for -audio tracks.
Multiple tracks per session are permissible.

The write modes for DVD+R both resemble DVD-R Incremental Streaming except
that with DVD+R each track gets wrapped in an own session. -sao does
reserve a track size whereas -tao writes the tracks open ended. They do not
make much difference in respect to the result, though.
