transporting liquids and items and some related devices.  Pipes and tubes can
go horizontally or vertically.  Item tubes can also be used for sorting items
and extracting items from chests or putting items in chests.  Autocrafters can
automatically follow craft recipes to make new items and can be fed by item
tubes.  Deployers can place items in the world as a player would.  Node
breakers simulate a player punching a node.")
