The PBI format re-implemented for FreeBSD and PC-BSD
Kristofer Paul Moore · 2010
The PBI format (Push Button Installer) has been the default package management system for PC-BSD going on 5+ years now. However as we looked to the future it became apparent that it was greatly needing an overhaul to both improve its functionality, and expand its usage outside the scope of just PC-BSD. Among the areas needing improvement were how it dealt with identical libraries between applications, the heavy requirements from being implemented in QT/KDE, and lack of a digital verification mechanism.
