+Mapgen objects
+---------------
+A mapgen object is a construct used in map generation.  Mapgen objects can be used by an on_generate 
+callback to speed up operations by avoiding unnecessary recalculations; these can be retrieved using the 
+minetest.get_mapgen_object() function.  If the requested Mapgen object is unavailable, or 
+get_mapgen_object() was called outside of an on_generate() callback, nil is returned.
+
+The following Mapgen objects are currently available:
+
+- voxelmanip
+    This returns three values; the VoxelManip object to be used, minimum and maximum emerged position, in that 
+order.  All mapgens support this object.
+
+- heightmap
+    Returns an array containing the y coordinates of the ground levels of nodes in the most recently 
+generated chunk by the current mapgen.
+
+- biomemap
+    Returns an array containing the biome IDs of nodes in the most recently generated chunk by the 
+current mapgen.
+
+- heatmap
+    Returns an array containing the temperature values of nodes in the most recently generated chunk by 
+the current mapgen.
+
+- humiditymap
+    Returns an array containing the humidity values of nodes in the most recently generated chunk by the 
+current mapgen.
