Neat.

I should mention that I didn’t maintain the Guile part in Hydra (which
is really just the ‘hydra-eval-guile-jobs.in’ script), so the latest
Hydra won’t work with Guix.  :-/

I think it’s “just a matter” of updating this script to produce JSON
instead of XML, but that has to be done (and I thought it’d be more
fruitful to invest in Cuirass).

ISTR that other changes were made that tie Hydra to Nix more closely,
and I’m not sure what the implications are.

Woow, congrats on getting this far!

Could you split it into separate packages: one for each new package, one
for each individual package change?

Thank you!
