RO (Repository Observer) is a complex tool that watches over systems and tied repositories. It gathers information about packages installed on observed systems and available updates for packages in repositories related to these systems, and helps one to determine which systems should be updated. It was originally designed ALT Linux distributions, but can probably be used with other RPM-based systems.
