It is mainly there to help with cleaning up repositories full of many releases of the same package and then making an RPM repository usable with yum on RHEL-based distributions. It runs fairly well on Debian if you install RPM tools and python libraries.

Source Ruckus Linux is an embeddable, robust Linux meta-distribution. It's a collection of build tools, source packages, scripts, and documentation all ready to be built into a Linux distribution. It can be used out-of-the-box, but its real strength lies in being used as a base for your own distribution. In other words, it exists purely to be forked, although it can be used as-is.
