I have been giving git a trial run for the past few weeks and I think I like it, so I will be switching Lyngo to use git in place of subversion. All the new stuff will go on git. Git has also the entire history of the project since the initial subversion checkin. Code older than that, which is coincidentally obsoleted is unavailable in git (and svn).
I am close to having a stable "quiz" app ready for release so you may see some files soon. Of course if you are feeling adventurous you can always compile the code from source control yourself and give it a whirl :)
Lyngo Drillbit has been checked in to CVS, it needs a lot of added features and the internals need some fixing, but it *does* work.
The file format spec is probably going to change rapidly soon and a program will be made to generate the drillbit files, for now it has to be done by hand. Some sample files are available in the lyngo/lessons/ cvs directory.
