My request is more general than that. The idea is that you could chain
*any* apt commands together as a single simulation. Such as, for example, a
sequence consisting of:

add-apt-repository -y ppa:footeam/foo
apt -y update
apt -y upgrade
apt -y install foo bar

However, install with "+" or "-" does solve my immediate problem, so thank
you for that, but I still think allowing arbitrarily complex simulations
would be a good idea, assuming it's not prohibitively difficult to
