Hi,

this patch series adds a few CD/DVD/Blu Ray Disc burning tools.

There is/has been some controversy about the license of cdrtools, 
with claims it cannot be distributed in binary form because it mixes 
CDDL and GPL code.  As far as I understand, mkisofs is GPL, while the 
other executables are CDDL, and I do not really see the problem.  If 
others disagree, or we want to be extra careful, I suppose we can 
disable substitutes for cdrtools, so we only distribute it as source?

cdrtools also bundles a forked LGPL-licensed copy of cdparanoia.  
This is perhaps unfortunate, but I don't think it's easy to unbundle 
it (cdrtools doesn't build agains our current cdparanoia).
