It helps you build packages quickly and easily (Packages like RPM and DEB formats). FUNDAMENTAL PRINCIPLE: IF FPM IS NOT HELPING YOU MAKE PACKAGES EASILY, THEN THERE IS A BUG IN FPM.

aptly is a swiss army knife for Debian repository management: it allows you to mirror remote repositories, manage local package repositories, take snapshots, pull new versions of packages along with dependencies, publish as Debian repository.
