+     "Pipeworks is a mod for Minetest implementing 3D pipes and tubes for
+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.")
