In-development, noncomplete, library used for collecting Git repository statistics. Lots of breaking changes happening.
Authors vs Committers
Right now it's assummed that the commit author == the committer. This could easily be separated into two, or taken as an option, whether to gather stats on the authors or committers.
Committer email
Currently committers are identified solely by their email address. Commits by committers with no email address is not supported.
