Modular Tunnel Boring Machine, aka
				  The Almighty Digtron
				  ====================

This mod contains a set of nodes that can be used to construct highly customizable and modular tunnel-boring machines, bridge-builders, road-pavers, wall-o-matics, and other such construction/destruction contraptions.

The basic nodes that can be assembled into a functioning digging machine are:

* Digger heads, which excavate material in front of them when the machine is triggered
* Builder heads, which build a user-configured node in front of them
* Inventory modules, which hold material produced by the digger and provide material to the builders
* Control node, used to trigger the machine and move it in a particular direction.

A digging machine's components must be connected to the control node via a path leading through the faces of the nodes - diagonal connections across edges and corners don't count.


Crafting recipes
================

All machine nodes are constructed from a "Digtron Core" craft item and other materials.

Digtron cores are made with the following recipe:
