A really simple utility for tracking things like commit size (only commit size now) in the git log for a user.
If you are me (Daniel Sellers) and you want the commit size limit to be 300 lines... then you can just run
git-goals. If not then you want to run
git-goals 'Your Git Author Name' number-of-lines
To install this wonder:
npm install -g git-goals
It also now outputs the number of reviews done vs the number of commits created. This works well with gerrit... and probably not super well with other things.
