That's kind of tricky since there are many files that contribute to any
particular build.  Especially the use of functions makes it hard to see which
file "defines" a package.  (For instance, ultimately almost all derivations are
"made" in mkDerivation stdenv/generic/default.nix.)

Another possibility is to have a meta.maintainer field containing the email
address of the person to be spammed when a package breaks.

But in the meantime, we should just re-enable sending messages to nix-commits.
And bring back the RSS feeds :-)

Eh.

Or just spam everybody who committed since the last successful build of the
package :-)
