The file selection/multi picker example at least can work with the fzf package alone. There are a bunch of files in shell/ from the tarball that enable a little magic like interactive history support and the inline picker. On Debian they're also installed in /usr/share/doc/fzf/examples/ for sourcing in your .${shell}rc.
