It fetches the latest version based on the bucketlist XML from commondatastorage and generates a "source.nix" which contains an attribute set about where to fetch the latest version. The XML is parsed in a somewhat hackish way using sed, but as this is just an updater, its okay and we don't want to break a fly on the wheel by employing a full XML parser.
