Cross the first TODO off the list: https://gist.github.com/mostthingsweb/39e24b329de70c0212e5bf21a431e143/8d1a5f51b3c0bf260c730ed5716d9807c78335b8

(BTW eventually I will move this to poky-contrib; gist is just more convenient for me for the short term. If there's a desire for it to happen sooner let me know.)
