> Apache seems to still use subversion which makes it a bit hard to easily get the raw statistics. Luckily there is a way to import it all into git, it just takes a really long time.
Apache has git-svn mirrors for their projects at http://git.apache.org/. Unfortunately, it does not seem to have a mirror for Apache OpenOffice yet.
Also, be careful when comparing the number of commits. Git and Subversion tend to encourage different commit patterns, so what is a lot of small commits in one could be a few large commits in the other. The same with the number of authors: Git has separate fields for "author" and "committer", while Subversion has only the committer.
