<DT>The goal is to provide some of cdrecord's options in a compatible way.
This has been achieved quite sufficiently for the needs of backup tool
<A HREF="http://scdbackup.sourceforge.net/main_eng.html">scdbackup</A>
and for data CD projects of <A HREF="http://www.k3b.org">K3b</A>
(see <A HREF="#examples">examples</A>).
Suitability for audio CD frontends has been improved much and is now being
evaluated.<BR>
Most DVD types are written in pseudo -tao modes which are very different
from the write mode DAO used by cdrecord(-ProDVD). With DVD-R[W] cdrskin
can use this write mode, too.<BR>
Further enhancements depend on people who can describe and discuss their
wishes as well as on the development of libburn.</DT>

cdrskin -scanbus or --devices hangs for quite a while if there is
a CD drive which does not work properly (e.g. because it has individual
problems with DMA).
So if the superuser gets no result with cdrskin --devices then one should
disable DMA with the problematic CD drives
(like: <KBD>hdparm -d0 /dev/hdd</KBD> )
and try again.<BR>
In severe cases it might be necessary to guess the device name /dev/sgN resp.
/dev/hdX of the non-ill burner if it cannot be found otherwise among its
ill peers. Alternatively one can guess the address of the ill device, remove
rw-permissions and retry the bus scan as non-superuser.

<CENTER><H3>About the relationship of cdrecord and cdrskin</H3></CENTER>
First of all: this relationship is single sided, as cdrskin has to be aware of
cdrecord but not vice versa.
<BR>
<BR>
I am a long time user of cdrecord and it works fine for me.
Especially i do appreciate its write mode -tao which allows to pipe arbitrary
data on CD and CD-RW via stdin. cdrecord is reliable, versatile and well
maintained. So for me - there would be not problem with it.
<BR>
But the author of cdrecord and the Linux kernel people foster a very hostile
relationship. Ok, that's their business, not mine (or ours if you are with me).
One has to be aware, though, that this relationship might lead to a situation
where cdrecord is no longer available for certain Linux kernels.
<BR>
To have my own project prepared for such a time, i began to implement its
cdrecord gestures on top of libburn.
From now on i invite other interested users of cdrecord to teach cdrskin
the gestures necessary for their cdrecord applications.
Contact me. Let's see what we can achieve.
<BR>
<BR>
libburn and cdrskin are now mature enough to substitute cdrecord in its
major use cases of CD burning. It is possible to foist cdrskin on various
software packages if it gets falsely named "cdrecord".
I do not encourage this approach, but of course such a replacement
opportunity is the goal of a cdrecord compatibility wrapper.
<BR>
<BR>
It is very important to me that this project is not perceived as hostile
towards Joerg Schilling and his ongoing work.
I owe him much. For cdrecord, for mkisofs, for star. Chapeau.
