ComputerCraft - Best Turtle Mining Script Tutorial

KiwiExcav Features:
- Allows near unlimited number of turtles able to all work together to mine in one spot
- Mines 4 blocks per move going down and 2 blocks per move going up, making them much more fuel efficient than other scripts that only mine 1-3 blocks per move.
- Pretty much can fuel themselves given a sufficient amount of starting fuel (coal)
- Automatically ejects cobble and dirt from inventory
- Can handle world and/or chunks being unloaded
- Can handle falling blocks like gravel
- Can handle mobs
- Setup is relative simple and flexible
- A single output chest is used (some other scripts involve placing multiple chest scattered around the mining area)

** Depending on your version of ComputerCraft, you might be able to skip the instructions regarding editing the 'pastebin' program.

Turtle setup instructions
1. copy /rom/programs/http/pastebin /pastebin
2. edit /pastebin
4. /pastebin get gufRiv2r startup (should see success messages here)
5. Hold ctrl+R to restart the computer
6. Script should automatically start after reboot now, follow instructions by pressing y twice

Faster startup for multiple turtles
1. Place disk drive next to turtle and a computer next to it, open the computer
2. copy /rom/programs/http/pastebin /pastebin
3. edit /pastebin
5. /pastebin get gufRiv2r turtleStartup
6. copy turtleStartup /disk/
7. goto turtle, copy /disk/turtleStartup startup
8. Hold ctrl+R to restart the computer
9. Script should automatically start after reboot now, follow instructions by pressing y once and then n
10. Mine the turtle and place it in the correct starting location for the quarry, the script should run again, press y twice.
11. Rinse and repeat steps 7-10 until desired # of turtles is reached

Controller computer setup
1. Place computer nearby to quarry site with wireless modem on right side
2. Place disk drive next to turtle and a computer next to it, open the computer
3. copy /rom/programs/http/pastebin /pastebin
4. edit /pastebin
6. /pastebin get tXNdyBe5 KiwiExcavController
8. (optional, but recommended) "label set ExcavController", so when you mine this computer up you don't have to do this setup again.
9. run KiwiExcavController (size of digsite)

Accidentally started turtle in the wrong place, turtle is otherwise acting weird, or the quarry has finished mining and you want to recover the turtle?
1. open turtle terminal and hold CTRL+T to stop the program
2. delete KiwiExcavMinerSave
3. mine turtle
4. Place back in proper quarry starting location (script should automatically run again), press y twice

I may be stupid, but I can't get the turtle to initiate the program. On craftos1.7, getting the error "Bios:14: [string "startup"]:1: unexpected symbol"
