If you insist that people learn to code in order to use technology, I'm going to insist that you grow your own flax, do the retting, spin it, weave it, and sew it before you're allowed to wear pants.
Also there's no documentation. Real shepherds, shearers, spinners, and knitters don't comment their code^H^H^H information on how any if this is done, so good luck. You'll end up with both a sweater and intact knees if you're hard enough.

Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.
