Dreamwidth Development Training

How does one update their repos on their hack now? The 'old' script no longer pulls anything for me (what used to be on http://wiki.dwscoalition.org/wiki/index.php/Dev_Maintenance) and I don't understand how I can keep up with changes. :/

(Context: I'm on Windows; I use PuTTY and WinSCP).

Edit: ok, if anybody else wonders, short answer is you can no longer update your hack using old methods. :/

Edit 2: long answer is you can switch to the new system. See comments for detailed instructions. :)
