The rpm packaging system is a very good tool (compared to tar.gz), but when you want to install a software foo, you often have to install some libraries too (libfoo1, libfoo2 ). Now when you remove the foo package, libraries are often forgotten, and the disk space is decreasing ...

Another case : when you upgrade your Linux box, you will also see forgotten packages (check with rpm -qa --last command !)

There is an easy way to check if a package is used or not : rpm -e --test package, but as I'm also working on Debian, I was surprised by the deborphan tool .

There was already some projects on rpmorphan, but none was more than a beta version, and none is currently alive. The goal of this project is to write a clone of deborphan for rpm users, and to have it stored on well-known server.
