Everyone knows there is a free source code application available for iPad named ComicFlow, but the source code is in the google source code - no download project link there.
I'm the owner of the project. What happened at that time is that one of ComicFlow's subrepositories (CocoaHTTPServer) was relocated from Google Code to GitHub and it prevented things to work correctly. I actually fixed this problem a while back.
I also just did some significant changes to ComicFlow and it depends quite less on external repositories so the checkout process should be quite smoother.
