From f8d91f20e6c88510282263715a1b87c99afad5a1 Mon Sep 17 00:00:00 2001

Subject: * Nix can now fetch prebuilts (and other files) from the network, iff
   a mapping from the hash to a url has been registered through `nix  
 regurl'.

* Bug fix in nix: don't pollute stdout when running tar, it made
  nix-switch barf.

* Bug fix in nix-push-prebuilts: don't create a subdirectory on the
  target when rsync'ing.
