Thanks, Larry. I know how to install/remove packages with apt-get, but
I'd like to review it's operations before it does anything. Especially
in the case of dependancies.

Of course. But that's not the detail I'm interested in. I want to know
what will be updated and to what version numbers. Not _after_ the
operation, but before.

I'm not talking about trying new packages. I want to know what apt-get
will do before it commits. This is a trivial feature and it's present
in other package managers. Hell, even Windows Update lets you know
what it's about to do and gives the user veto option. I find it
difficult to believe that apt-get forces one to do a simulated install
as the only means of discovering what it intends to do. Is there
really no interactive option?
