-The map data serialization version used is 22. It does not fully specify every
-aspect of this format; if compliance with this format is to be checked, it
-needs to be done by detecting if the files and data indeed follows it.

Legacy stuff
=============
Everything is contained in a directory, the name of which is freeform, but
often serves as the name of the world.
-Currently the authentication and ban data is stored on a per-world basis. It
-can be copied over from an old world to a newly created world.

Format of nodes
----------------
A node is composed of the u8 fields param0, param1 and param2.
-The content id of a node is determined as so:
-- If param0 < 0x80,
- content_id = param0
-- Otherwise
- content_id = (param0<<4) + (param2>>4)
+if map format version <= 23:
+ The content id of a node is determined as so:
+ - If param0 < 0x80,
+ content_id = param0
+ - Otherwise
+ content_id = (param0<<4) + (param2>>4)
+if map format version >= 24:
+ The content id of a node is param0.
The purpose of param1 and param2 depend on the definition of the node.

+Static objects are persistent freely moving objects in the world.

+Itemstring format
+------------------
+eg. 'default:dirt 5'
+eg. 'default:pick_wood 21323'
+eg. '"default:apple" 2'
+eg. 'default:apple'
+- The wear value in tools is 0...65535
+- There are also a number of older formats that you might stumble upon:
+eg. 'node "default:dirt" 5'
+eg. 'NodeItem default:dirt 5'
+eg. 'ToolItem WPick 21323'
+
Inventory serialization format
-------------------------------
- The inventory serialization format is line-based
