Hm, the progress bar is used to indicate progress in the process of
installing packages, right? I think that this doesn't belong (entirely) in
the aptitude layer; at the very least, apt should be responsible for keeping
track of how much progress has been made in installing packages. This should
be done by using an instance of the OpProgress class, which could then be
specialized to provide output in whatever format you want (the specialization
might make more sense in aptitude, but then again it sounds generically
useful enough that you might want to put it into apt).
