Which Git commit stats are easy to pull

Question

Previously I have enjoyed TortoiseSvn\'s ability to generate simple commit stats for a given SVN repository. I wonder what is available in Git and am particularly interested

Answer 1

Note that, if your repo is on GitHub, you now (May 2013) have a new set of GitHub API to get interesting statistics.
See "File CRUD and repository statistics now available in the API"

That would include:

• Contributors
• Commit Activity
• Code Frequency
• Participation
• Punch Card
