Where are the "managed project source files"?

Trying to follow this tutorial

Walkthrough: Part 1 - Creating a Basic Project System

And I got to this step:

Locate the managed project source files by following this link. Copy these files to a local folder named, for example, C:\MyLocalFolder\Project

But that codeplex project doesn't have any downloads... so what files am I supposed to copy?

The Microsoft employee that worked on that got hit by a bus. That happens, the traffic congestion in Redmond is epic. It didn't progress to an official downloadable release version, you have to hump the check-ins. Following the links takes me to this page, the download link at the upper right corner is active for that one. Looks complete, didn't try it.

Oops... I've I read the page in its entirety, I would have noticed I was supposed to get it from the Source Code tab.
