The gem is pretty cool. It runs from the command-line (or via rake) and has a few fixes from the Rails code.

I’m happy to work on turning this into a PR to remove the code from Rails and move code_notes into the Rails namespace, if there’s interest.

(Given that my PR for GitHub - bf4/code_metrics: Extracting Code Statistics from rails was first approved then rejected, I’m not going to invest any effort in a PR unless someone on the core team takes ownership of shepherding the code/me through the process)
