It's very dumb, really: it just drops the output of `guix package
--search "."` to a file :D

Well, you can use `recsel' or any text processing tool over it, but
beside that, not much I'm afraid.

In terms of caching, nothing, but the Helm interface has some
significant perks over emacs-guix:

- Perform transactions (install/remove) over multiple packages.

- Perform actions over multiple packages: browse home-page, show
(reverse) deps, find-files (with helm-find-files -- awesome! :p).

That's about it.  It's much more basic than emacs-guix but convenient
enough that I still find some use for it :)

That said, this `helm-system-packages-guix.el` was mostly a proof of
concept, it's far from being as neat and complete as emacs-guix.
A proper Helm/Ivy interface for emacs-guix would be much better,
maybe some day.
