nixpkgs/maintainers/scripts/copy-tarballs.sh
Eelco Dolstra ecd43e2bfe * Updated the script that copies tarballs used in Nixpkgs to
nixos.org/tarballs.  It no longer greps the source for fetchurl
  calls, because a lot of URLs are now computed
  (e.g. "http://foo/${name}.tar.bz2").  So instead we evaluate the Nix
  expression with "nix-instantiate --xml --strict" and look for URLs
  in the result.  Because I'm lazy the script no longer checks whether
  the hash of the download matches the hash in the expression.
