I've called it -materials now, I doubt that makes a big difference. I
don't know any policy about packages having to use -data. I think most
of the stuff are material definitions in the package, so I think it's fine.
I don't want to split them again, Debian's ftp masters like to start to
grumble if a package builds too many small packages.

If you're facing such questions - the Debian policy is what you want to
read: http://www.debian.org/doc/debian-policy/ch-binary.html#s3.1

radiance is NOT in non-free. It is in Debian/main.
Actually the license is a bit weird, it's similar to the php license
with some name changes, but it's fine for main.
You're probably thinking abut the .dfsg. in the version number - it just
means I had to remove two pdf files which are shipped without source.
Seems the source of one of them is lost, and Greg will ship the other
files's source with 3R9, or they're removed both by him. THen the .dfsg.
is gone, too. Nothing that stops a package from going into main, though.

If I remember right Lars build those packages. I know they exist, but
usually it is faster for me to repackage things from ground of then
trying to understand what other people did and doing things based on that.

I gave it a thought, too, but discarded that for now as the dependency
to x11 only brings a few hundred k of extra libraries. I doubt that's
worth the work. You don;t need to install X completely on Debian...

I doubt it is worth to read trough the whole thread. But if it's ok for
Greg I'll create a summary of the interesting parts of it.

About libtiff: if I remember it right (without reading trough the 30
mails again), the reason why there's one shipped in radiance is that the
libtiff in BSD was broken, or so. Anyway I have no other chance then
using Debian's libtiff, I'd get slapped by the ftp masters if I'd try to
add the source of an old version of libtiff to Debian - it's a waste of
space and another thing you need to patch if there's a security hole in
