--[[
Version 3.1.1
Recent Changes:
1. Now has session persistence! Just type "quarry -restore"
   and your turtle will pick up where it left off
2. New Argument: startY to help stop it from getting stuck on those nasty sheep!
3. Most directional functions take care of invert. Exception is turtle.detect
]]
--[[ToDo:
1. Actually get the rednet send back and forth to work
3. Send basic commands from receiver program e.g. Stop
6. Add in rednet stuff
7. Massive update for rednet program
]]

-------Defaults for Arguments----------
--Arguments assignable by text
x,y,z = 3,3,3 --These are just in case tonumber fails
inverted = false --False goes from top down, true goes from bottom up [Default false] 
rednetEnabled = false --Default rednet on or off  [Default false]
--Arguments assignable by tArgs
dropSide = "front" --Side it will eject to when full or done [Default "front"]
careAboutResources = true --Will not stop mining once inventory full if false [Default true]
doCheckFuel = true --Perform fuel check [Default true]
doRefuel = true --Whenever it comes to start location will attempt to refuel from inventory [Default false]
invCheckFreq = 10 --Will check for inventory full every <-- moved spaces [Default 10]
keepOpen = 1 --How many inventory slots it will attempt to keep open at all times [Default 1]
fuelSafety = "safe" --How much fuel it will ask for: safe, moderate, and loose [Default moderate]
saveFile = "Civil_Quarry_Restore" --Where it saves restore data [Default "Civil_Quarry_Restore"]
doBackup = true --If it will keep backups for session persistence [Default true]
--Standard number slots for fuel (you shouldn't care)
fuelTable = { --Will add in this amount of fuel to requirement.
safe = 1000,
moderate = 200,
loose = 0 } --Default 1000, 200, 0

}

local help_paragraph = [[
-DEFAULT: This will ignore all arguments and prompts and use defaults
-vanilla: This will ignore all arguments except for dimensions
-dim: [num] [num] [num] This sets the dimensions of the quarry
-invert: [t/f] This sets whether invert is true or false
-rednet: [t/f] This sets whether it will attempt to make a rednet connection
-sendChannel: [num] This sets the channel the turtle will attempt to send on
-receiveChannel: [num] This sets the channel the turtle will attempt to receive on
-doRefuel: Changes whether or not the turtle will refuel itself with coal when fuel is low (opposite of written config)
-doCheckFuel: Changes whether or not the turtle will check its fuel level before running (opposite of written config)
-chest: [chest side] Changes what side turtle will output to
-startY: [num] Tells the turtle what y coordinate it starts at, to make bedrock checking more accurate (hopefully)
-keepOpen: [num] How many slots of the inventory turtle will try to keep open (Will then auto-empty)
-invCheckFreq: [num] How many blocks before full inventory checks
-saveFile: [word] Changes where the turtle saves its backup to.
-doBackup: [t/f] Whether or not the turtle will backup its current position to a file.
-restore: Turtle will check for a save file. If found will ignore all other arguments.
-fuelSafety: [safe/moderate/loose] How much extra fuel the turtle will request at startup
Examples [1]:
 The minimum amount necessary to start a turtle automatically would be one of these two
 ---------
 quarry -dim 3 3 3 -invert false -rednet false
 ---------
 quarry -dim 3 3 3 -vanilla
 ---------
 or, if you actually wanted a 3x3x3 then
 ---------
 quarry -DEFAULT
Examples [2]: 
 If you wanted start a quarry that has 
 rednet on channels 500 and 501, outputs 
 to a chest below itself, is inverted,
 and has the dimesions 5x5x21, then here
 is what you would type: (Remember that
 order does not matter)
 ----------
 quarry -receiveChannel 501 -sendChannel 500 -invert true -dim 5 5 21 -chest bottom -rednet true
Examples [2] (cont.):
 Now, this may be very long, but it is meant for people who want to make automated quarries with
 the same settings every time (or with variable setting)
Examples [3]:
 If you are playing softcore then you
 can do
 ---------
 quarry -doCheckFuel false
 ---------
 Followed by any other arguments
Tips:
 You don't actually have to type out "false" or "true" if you don't want. It actaully just checks if the first
 letter is "t", so you (usually) don't have to put anything at all. Putting the whole word just helps with clarity
Internal Config: 
 At the top of the program, right below the changelog is a written config. Anything not specified by arguments
 will be taken from here. If you have a quarry setup you use a lot, you could just edit the config and then
 type in the following:
 ----------
 quarry -DEFAULT
