Support for non-Debian distros

[Nagakamira]

Hi, I found certain distros which are using dpkg package manager as its
default package management system. There's about 2: UHU Linux and Ataraxia
Linux (and Yocto but .deb format can be used optionally). But they aren't
based on Debian (or on its derivative). For example, UHU and Ataraxia are
using repositories which are compatible with APT. That would be great if
you can add support for them.
