+Node Metadata
+-------------
+The instance of a node in the world normally only contains the three values
+mentioned in "Nodes". However, it is possible to insert extra data into a
+node. It is called "node metadata"; See "NodeMetaRef".
+
+Metadata contains two things:
+- A key-value store
+- An inventory
+
+Some of the values in the key-value store are handled specially:
+- formspec: Defines a right-click inventory menu. See "Formspec".
+- infotext: Text shown on the screen when the node is pointed at
+
+Example stuff:
+
+local meta = minetest.env:get_meta(pos)
+meta:set_string("formspec",
+        "invsize[8,9;]"..
+        "list[context;main;0,0;8,4;]"..
+        "list[current_player;main;0,5;8,4;]")
+meta:set_string("infotext", "Chest");
+local inv = meta:get_inventory()
+inv:set_size("main", 8*4)
+print(dump(meta:to_table()))

+        infotext = "Chest"
+    }
+})
+
+Formspec
+--------
+Formspec defines a menu. Currently not much else than inventories are
+supported. It is a string, with a somewhat strange format.
+
+Spaces and newlines can be inserted between the blocks, as is used in the
+examples.
+
+Examples:

+    list[current_player;craft;3,0;3,3;]
