RPM Auto-Installer and/or FTP Mirrorer mirror RPMs from an FTP site, keep installed RPMs consistent with an FTP site or local directory, and keep installed RPMs in a cluster or network of systems consistent. It is highly flexible and even contains a very nice, menu-driven Interactive-Install mode.

The interactive mode lets you actually install the updates (by default, RPMs are not upgraded automatically, although they can be). You can also use the interactive mode to process a directory of RPMs. AutoRPM will compare each file with your installed RPMs and allow you to decide which ones to install.
