Now that the project has been renamed, the mercurial source repository has also changed from ggxdev to MoxieDev. This repository contains the entire toolchain, simulators and benchmark programs. You can check the entire thing out like so...
$ hg clone http://mercurial.intuxication.org/hg/moxiedev
I've also created a wiki, explaining how to check out, build and use the tools. It's all here: http://moxielogic.org/wiki.
