RpmLevel allows you to do a number of querying operations that are not possible by using the rpm program only. For example, it keeps track of the system area levels with respect to the original distribution of the CD and provides a quick idea of Not-Installed packages, Upgraded packages, Downgraded packages and Extra (third party) packages. It has been planned and tested with Red Hat systems, but with some modifications it should also work on other RPM-based systems like SuSE and Mandrake.
