configure-layer.rkt it is then :)

I'd write this as 
--8<---------------cut here---------------start------------->8---
(list
 ... 
 libedit
 racket-minimal
 (simple-racket-origin
  "2d" (base32 "1zzcz5qyjv7syi41vb8jkxjp1rqgj61zbsdrg0nlc4qy9qsafzgr")
  '("2d" "2d-doc" "2d-lib")
 (simple-racket-origin
  "algol60" (base32
"09kj6asypmc24n29w0izc9p0q8hpga2hpkchsypfwn5c8zpvihlx")
  '("algol60" ".")
 ...)
--8<---------------cut here---------------end--------------->8---
I do wonder whether these packages can further be modularized (i.e. so
that they build as packages) with configure-layer.rkt acting as a
profile hook and some racket meta package simply adding racket-minimal
and all the base stuff into the profile, but for now let's just have an
easy way of formulating origins.
