+--[[ USING ENTRY ALIASES
+	Sometimes, mods register multiple items for basically the same thing in different “states”.
+	One example is the furnace from Minetest Game (default:furnace and default:furnace_active).
+	If the node in all “states” is similar enough, you might consider to suppress the entries
+	of some of the entries in order to concentrate information on a single entry. If you do this, you
+	also have to register aliases since the lookup tool will stop working on nodes with suppressed
+	entries.
+	Suppressing entries may also be useful to combine large lists of similar items, but be careful
+	not to overdo it and throw away potentionally valuable information in the process.
+
+	The following code shows two nodes which changes its textures when punched.
+	For the player, doc_example:node2 is basically the same as doc_example:node1, only with a
+	different textures. Only one entry is created for both nodes.
