* A function to fetch sources from a Subversion repository. svn path=/nixpkgs/trunk/; revision=544 2003-11-25 17:38:48 +00:00			`. $stdenv/setup`

* `fetchsvn' now requires the MD5 hash (as computed by `nix-hash') of 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 2004-04-14 11:55:33 +01:00			`header "exporting $url (r$rev) into $out"`
