pkgin is aimed at being an apt / yum like tool for managing pkgsrc binary packages. It relies on pkg_summary(5) for installation, removal and upgrade of packages and associated dependencies, using a remote repository.
I love this tool. I first encountered it, I think, in DragonFly BSD, and really enjoyed using it. Later I encountered it again with netBSD, and then also found out that it could actually work on a wide variety of *n?x platforms. I love cross-platformedness, and I love smart installers, and this is both. Highly recommended.
