I've made small C# utility to generate LOC charts for git repository. It's quite fancy and the other reason was to learn using github. The code is definitely not the art of computer programming and to be honest quite slow (anyway, git on Windows is slow) but anyway MUCH faster than any other svnstat-like tools: it took 6 minutes to generate stats for 80KLOC with about 2000 commits. I don't remember how long did it take with svnstat but it was hours. And the project was much smaller that days.
