The turtle should be placed in front of the basin that the gravel goes into facing it, with a faucet above the basin. The turtle should have a block that can carry redstone signals (I like using a redstone lamp) directly above it - this will trigger the faucet. A fuel source (such as coal, coal coke, etc.) should be in inventory slot 16. Gravel should be in inventory slot 15. As long as there is gravel in inventory slot 15, gravel in any of the other inventory slots can be used, and the gravel in inventory slot 15 will be used last.

The program takes one argument, which is the number of blocks of gravel to turn into brownstone.
