rpmtool is a small tool that can be useful while managing rpm files. It can find obsolete or non-obsolete rpms in a specified directory. It can find updates in one or more mirror directories full of rpms for a set of rpms in a target directory. I use it to manage updates of my local rpm repositories, which consist of hand selected rpms from different vendors. It is quite fast, mostly because it uses the ocarpml library, written by Martin Biely.
