Create a new version of paste:

-- This program creates a tunnel facing to facilitate mining via 5 x 5 tunnels
-- Pastebin code = "LptADyfD"; Pastebin name is "MDC_Tunnel_Facing"

-- Place the turtle down on the right-forward end of the tunnel cut
-- Place coal into Turtle slot #14 to assure adequate fueling
-- Place netherite into Turtle slot #15 and #16 to assure adequate placement resources
-- The program wants to know the options how many blocks you want to move forward before facing
-- The options are RC - Right Corner; LC - Left Corner; CS - Center Section
-- An example is RC 2; Right corner facing two blocks forward from turtle placement

	if turtle.detect() then turtle.dig(); turtle.forward() else turtle.forward() end
