This (WECL) and the valtan[0] project are both very exciting initiates to get CL into the browser. I would love to see a comparison between these two implementations, as they seem to be coming at the problem from opposite directions.

There's one more that restarted active development recently: JSCL https://github.com/jscl-project/jscl

The main VCS is Fossil! I love seeing projects use Fossil rather than git.

to be honest I feel much more comfortable with git -- muscle memory, magit etc., but fossil is much more appealing when you look at the underlying model and how it bundles wiki and issues along with the repository; that's why I'm starting as of late all my solo projects with fossil repo.
