Kubernetes - who wrote

gistfile1.md

gitdm (git data mine) is a tool written by Jonathan Corbet at LWN which he uses to do his 'who wrote the kernel' articles. I spent a couple of minutes (ended up being a couple of hours hacking on gitcm) to run it against kube.

I explicitly ignore merge commits and generated filed (Sorry Patrick Reilly, you had the some huge generated files).

My list of files/dirs I'm ignoring:

• Godeps
• third_party
• api/swagger-spec
• pkg/ui/datafile.go
• www/.*/shared/assets/sampleData1.json
