+	Minetest Schematic File Format
+
+	All values are stored in big-endian byte order.
+	[u32] signature: 'MTSM'
+	[u16] version: 4
+	[u16] size X
+	[u16] size Y
+	[u16] size Z
+	For each Y:
+		[u8] slice probability value
+	[Name-ID table] Name ID Mapping Table
+		[u16] name-id count
+		For each name-id mapping:
+			[u16] name length
+			[u8[]] name
+	ZLib deflated {
+	For each node in schematic:  (for z, y, x)
+		[u16] content
+	For each node in schematic:
+		[u8] param1
+		  bit 0-6: probability
+		  bit 7:   specific node force placement
+	For each node in schematic:
+		[u8] param2
+	}
+
+	Version changes:
+	1 - Initial version
+	2 - Fixed messy never/always place; 0 probability is now never, 0xFF is always
+	3 - Added y-slice probabilities; this allows for variable height structures
+	4 - Compressed range of node occurence prob., added per-node force placement bit
