"The primary command line tool is aptitude. apt-get fulfills a similar purpose and although it is no longer the recommended primary tool some still use it."
If you prefer the apt-* commands: "You can also use Wajig, for an unified and more logical command-line interface to all package management functions." (Apparently, apt is the new Wajig, except that apt doesn't automagically sudo, which Wajig did.)
"The upgrade process for some previous releases recommended the use of aptitude for the upgrade. This tool is not recommended for upgrades from wheezy to jessie."
See https://www.debian.org/releases/stable/amd64/release-notes/c...

2. Why full-upgrade and not dist-upgrade like in all the other debian package managers? Would that little bit of internal consistency really have hurt?
3. Still does not seem to cover all use cases.
