 --[[ Running this script on a turtle with saplings in slot 1, bone-meal in slot 2 and coal in slot 16 and a chest behind the turtle for the wood drop off point will create an automatic tree farm. combining this with a chest to the left of the turtle for sapling replenishment and chest to the right for coal replenishment will ensure a long running automated process.]]
