APT (Advanced Package Tool) is a dependency tool, well known to Debian users since it is used by default with their dpkg packages. But apt has been ported to work with rpm packages too, by Conectiva, who has now used it for some time in their GNU/Linux distribution. The good news is that apt for rpm may be used with any other rpm-based distribution. All you need is the tool compiled for your version of rpm and at least a repository where rpm packages and their apt metadata can be downloaded from.
