* Reverted r6713, r6711, r4623, r3660, r2237. There rewrote fetchurl URLs to http://nix.cs.uu.nl/dist/tarballs. With content-addressable mirror support (r9190, NIXPKGS-70) this is no longer necessary: fetchurl will try to download from that location automatically. So we can keep the original URLs. svn path=/nixpkgs/trunk/; revision=9192 2007-08-24 14:32:36 +02:00			`url = http://www.haskell.org/happy/dist/1.14/happy-1.14-src.tar.gz;`
