Best Turtle Program ?

I'm new to the forums and am now good at Lua.
I was wondering what's the best or most advanced Lua Program for TurtleOS

I wanted one that could dig down to a certain level. (say 12) then dig out till it's inventory was full then return the way it came?
Another program that when placed within radius of a tree it would go to town on that tree.

Is this even possible for the program currently? as in self awareness and if a mod had this already can i be linked to it? Im quite knew so might be quite newby to this stuff. I hear rednet a lot but what is it? Is it a Lua Program built by someone on the community or is it automatically installed in the mod.

Thanks to anybody who helps for the patience and helpfulness. :(/>/>

well, it's possible, my turtle API has a location function, just make it dig down until it's at layer 12 then do whatever you want and use goToPos to return to the surface. I will be adding an auto-mining function shortly.

Thanks man. I'm messing around with turtle.dig and stuff :(/>/>

pre installed in computer craft. need eloraam redpower mod installed for it to work though. Enables network though wireless modem blocks or bundled cables. Very cool things can be built with it.

rednet requires redpower if you are using it to send data across cables, if you are using modems rednet does not require redpower
