You can't install this with cargo. Una is a Haskell program; you can get it with `stack install una`.

Whoops, good point. In the long run I think Una's a good candidate for being installed at the systems level, because you really want to install unzip, etc. along with it.

EDIT: The idea being that if you install it with your system package manager it can have unzip etc. as dependencies so that's taken care of automatically.
