README

sw is very much inspired by HP-UX's SD-UX (the swlist, swinstall, swcopy, etc. series of commands). It is a reimplementation of these commands on top of a more basic package management system: the RedHat Package Manager (RPM). Ultimately, sw could be seen as yum or apt-get on steroids.

One of the main motivations behind that is the incredible versatility of SD-UX's filters and predicates.
