Re: low-hassle build-output excerpt retrieval

[Glenn Morris]

I'm no expert, so there may be better ways, but two ideas:

1) simply write whatever you want to stdout, so you can see it in the
build log.

2) Have a look at what emacs/release.nix does in its coverage job.
Specifically, the part where stuff is added to

  $out/nix-support/hydra-build-products

These files then become downloadable from the build page.
Eg http://hydra.nixos.org/build/17636523
  "Files test-logs.tar of type test-logs".

(The only thing I'm not sure of is, if your job actually fails, it may
not get as far as creating this file.)
