A so-called “meta distribution”, allows you to mix and match packages from some other distros. Kinda like distrobox, but older (AFAIK) and low level-er.
That said, I didn’t find it exactly useful a few years ago, since pretty much everything i needed was in the aur or the official repos (should be better if the base was smth like Ubuntu)

Pretty regular stuff if you ask me
