-===========================================================
-Minetest World Format used as of 2011-05 or so (deprecated)
-===========================================================
-
-Map data serialization format version 17.
-
-0.3.1 does not use this format, but a more recent one. This exists here for
-historical reasons.
-
-Directory structure:
-sectors/XXXXZZZZ or sectors2/XXX/ZZZ
-XXXX, ZZZZ, XXX and ZZZ being the hexadecimal X and Z coordinates.
-Under these, the block files are stored, called YYYY.
-
-There also exists files map_meta.txt and chunk_meta, that are used by the
-generator. If they are not found or invalid, the generator will currently
-behave quite strangely.
-
-The MapBlock file format (sectors2/XXX/ZZZ/YYYY):
--------------------------------------------------
-
-NOTE: Byte order is MSB first.
-
-u8 version
-- map format version number, this one is version 17
-
-u8 flags
-- Flag bitmasks:
-  - 0x01: is_underground: Should be set to 0 if there will be no light
-    obstructions above the block. If/when sunlight of a block is updated and
-	there is no block above it, this value is checked for determining whether
-	sunlight comes from the top.
-  - 0x02: day_night_differs: Whether the lighting of the block is different on
-    day and night. Only blocks that have this bit set are updated when day
-	transforms to night.
-  - 0x04: lighting_expired: If true, lighting is invalid and should be updated.
-    If you can't calculate lighting in your generator properly, you could try
-	setting this 1 to everything and setting the uppermost block in every
-	sector as is_underground=0. I am quite sure it doesn't work properly,
-	though.

-zlib-compressed map data:
-- content:
-  u8[4096]: content types
-  u8[4096]: param1 values
-  u8[4096]: param2 values
-
-zlib-compressed node metadata
-- content:
-  u16 version (=1)
-  u16 count of metadata
-  foreach count:
-    u16 position (= p.Z*MAP_BLOCKSIZE*MAP_BLOCKSIZE + p.Y*MAP_BLOCKSIZE + p.X)
-	u16 type_id
-	u16 content_size
-	u8[content_size] misc. stuff contained in the metadata
-
-u16 mapblockobject_count
-- always write as 0.
-- if read != 0, just fail.
-
-foreach mapblockobject_count:
-  - deprecated, should not be used. Length of this data can only be known by
-    properly parsing it. Just hope not to run into any of this.
-
-u8 static object version:
-- currently 0
-
-u16 static_object_count
-
-foreach static_object_count:
-  u8 type (object type-id)
-  s32 pos_x * 1000
-  s32 pos_y * 1000
-  s32 pos_z * 1000
-  u16 data_size
-  u8[data_size] data
-
-u32 timestamp
-- Timestamp when last saved, as seconds from starting the game.
-- 0xffffffff = invalid/unknown timestamp, nothing will be done with the time
-               difference when loaded (recommended)

-Node metadata format:

-
-Sign metadata:
-  u16 string_len
-  u8[string_len] string
-
-Furnace metadata:
-  TBD
-
-Chest metadata:
-  TBD

-Locking Chest metadata:
-  u16 string_len
