    Simple script demonstrating:
        - os object and os.sleep() method
        - while and for loops
        - If statements

os.sleep(2)      -- pause for 2 secs to allow time to press esc key
turtle.dig()     -- dig base of tree
turtle.craft()   -- craft wood to planks(1 wood or 1 planks = 15 fuel)
turtle.refuel()  -- add 4 x 15 fuel (1 wood crafts to 4 planks)
turtle.forward() -- go under tree

-- Loop to climb up tree and harvest trunk and surrounding leaves
while turtle.detectUp() do -- continue loop while block detected above
  turtle.digUp() -- Dig block above
  turtle.up()    -- Move up
  -- Inner loop to check for leaves
  for i = 1, 4 do
    if turtle.detect() then -- check if leaves in front
      turtle.dig() --Dig leaves
    end
    turtle.turnRight()
  end
end

-- At top of the tree. New loop to return to ground
while not turtle.detectDown() do -- While nothing detected below
  turtle.down() -- Go down
