At present, the target is the Ubuntu SDK, although this will be explicit
in the packages which rely on it ("Click-Framework: ubuntu-sdk-13.10"
etc.).

They will not be small. :-)

This just seems to be a complex enough case that it's simply not a good
target for this packaging system. I'm OK with that. As I said, this is
not trying to be a complete replacement for debs, because if it tried to
do that it would rapidly turn into a second system with a different set
of flaws.

The unpacked package directory will not be writable by the ordinary user
or the application directly, and should therefore not change. As such,
I don't think a restore feature should be necessary.

Yes. There'll be a symlink to the current version for convenience.
