Fine, post insert 3 spots back:
This page has some useful information.
http://code.google.com/p/zero-k/wiki/Developing"Using subversion" and "Tweaking game using subversion walkthrough" parts are the most relevant. I'll give a quick rundown:
* Make a copy of 85.0 from Spring/Engine, put it outside the spring my documents place.
* Add this path to the copy; "games/zk.sdd"
* Get am SVN program. Tortise SVN link is on that wiki page.
* Do most of the other stuff under "Using subversion"
* Through spring.exe you should now be able to run "Zero-k $VERSION", this version is the sdd. You can change the sdd while spring is running to reload things like widgets and gadgets.
* Get a google account for google code.
* When you've done that ask someone for commit rights for your google account. According to the admin area these accounts are capable of doing that:
