How Does It Work

The code goes over all commits messages and looks for the number of lines added/removed and keeps an updated count. Caveat: the lines reported in git commit messages are only a proxy for the true number of lines of code. It could be way off in projects in which there are data artifacts such as big data files. One solution is to loop over all commits, checkout the commit and do a wc over all files that are considered to be code files. But that's slower and could be dangerous in dirty projects.
