This is exactly the problem : it should be apt-get's job ; not more than that.

I was thinking about cubicweb itself : now that debian has changed the
default policy regarding recommanded packages (now installed by
defaut), I think cw has too much unnecessary dependencies : more than
that, these dependencies are only "packaging driven", cw code itself
does not require all this (and I know you just worked avoiding fop as
a cw dependency, which is a step back to the right direction : keep cw
dependencies minimal, unless it is really helpful for every end-user).

Will this tool include logilab.common, yams, rql, indexer, and so on ?
I was rather thinking of forest snapshots or so ; I currently use my
own (too) simple bash scripts to achieve this, and it is really a pain
to maintain for a non cw developper, forest snapshots would be nicer
if they still exist.
