Yes, i know, i was only speaking about the debian gnome 2 packages.

But then, redhat don't ships as many package as debian does, and you
have to take archive bloat and bandwith and maintainership cost and
other such in account, but then, i am hardly the right person to ask
But then, i seriously doubt that even if you go this way that it would
make sense to have a separate slim package.

Yep, that would be a nice solution.

Exactly, but cairo is not (yet ?) even comparable in size to gtk or
gnome, isn't it ?
Having 4 smallish source package which each build depend on the other is
a pain, and can cause terrible havoc to the autobuilder network (which
each in turn have to wait for the 4 others to be built, accepted,
installed, and so it would take 4 autobuilder cycle to build them. And
then, if you are not strict enough in the dependencies, it can happen
that one some architectures, cairo is built against an older version of
the other libraries and such, which is something that can quickly become
a maintenance nightmare.

Yes, that would be a good step.
But what about slim. Surely 3 smallish include files don't warrant a
separate package too.

They are already packaged by most distrib, so you just need to depend on
them, and everything should work out fine.

I will let you know the response of the debian ftp-masters when i will
upload the slim package :)))
