the tree being fetched from a Subversion repository. The revision number is now optional (and defaults to HEAD). This makes `fetchsvn' more pure. First, a URL/revision tuple does not uniquely identify a file resource, since the repository itself might change. Second, `svn:external' attributes can cause arbitrary resources to be exported. A script `nix-prefetch-svn' has been provided to determine the hash of a URL. svn path=/nixpkgs/trunk/; revision=938
