 This mod uses nodeboxes to supply a complete set of 3D pipes and tubes, 
 along devices that work with them.

 Unlike the previous version of this mod, these pipes are rounded, and when 
 placed, they'll automatically join together as needed.  Pipes can go vertically

+--    at the recipient, perhaps in violation of the previous cleaning rule or
