The past two days i finally did what i have been wanting to do for a while, rewrite the 'statistics and builds' thingy running on http://dev.infonet.dk - the last version was just a compilation of shell scripts, but i've written a new tool called iProjects (oh yes, very bad name indeed) - that can not only generate source code statistics - but also the branch tree - and all extracted from the source code management system of your choice (only Bazaar 1 / Tom Lord's Arch implemented so far, but it should be pretty simple to implement new backends like Subversion or CVS).

A really nice branching graph is the one for Vertigo (also featured as this post's thumbnail).

It still needs a bit more polishing on the source statistics graphing stuff, and the build system needs to be implemented, but the bulk of it is there, and there is already an debian package called iprojects available.
