+Give Initial Stuff API
+----------------------
+
+`give_initial_stuff.give(player)`
+
+^ Give initial stuff to "player"
+
+`give_initial_stuff.add(stack)`
+
+^ Add item to the initial stuff
+^ Stack can be an ItemStack or a item name eg: "default:dirt 99"
+^ Can be called after the game has loaded
+
+`give_initial_stuff.clear()`
+
+^ Removes all items from the initial stuff
+^ Can be called after the game has loaded

+TNT API
+----------
+
+`tnt.register_tnt(definition)`
+
+^ Register a new type of tnt.
+
+ * `name` The name of the node. If no prefix is given `tnt` is used.
+ * `description` A description for your TNT.
+ * `radius` The radius within which the TNT can destroy nodes. The default is 3.
+ * `damage_radius` The radius within which the TNT can damage players and mobs. By default it is twice the `radius`.
+ * `disable_drops` Disable drops. By default it is set to false.
+ * `ignore_protection` Don't check `minetest.is_protected` before removing a node.
+ * `ignore_on_blast` Don't call `on_blast` even if a node has one.
+ * `tiles` Textures for node
+  * `side`  Side tiles. By default the name of the tnt with a suffix of `_side.png`.
+  * `top`  Top tile. By default the name of the tnt with a suffix of `_top.png`.
+  * `bottom` Bottom tile. By default the name of the tnt with a suffix of `_bottom.png`.
+  * `burning` Top tile when lit. By default the name of the tnt with a suffix of `_top_burning_animated.png".
+
+`tnt.boom(position, definition)`
+
+^ Create an explosion.
+
+* `position` The center of explosion.
+* `definition` The TNT definion as passed to `tnt.register`
+
+`tnt.burn(position)`
+
+^ Ignite TNT at position
+
+
+To make dropping items from node inventories easier, you can use the
+following helper function from 'default':
+
+default.get_inventory_drops(pos, inventory, drops)
+
+^ Return drops from node inventory "inventory" in drops.
+
+* `pos` - the node position
+* `inventory` - the name of the inventory (string)
+* `drops` - an initialized list
+
+The function returns no values. The drops are returned in the `drops`
+parameter, and drops is not reinitialized so you can call it several
+times in a row to add more inventory items to it.
+
+
+`on_blast` callbacks:
+
+Both nodedefs and entitydefs can provide an `on_blast()` callback
+
+`nodedef.on_blast(pos, intensity)`
+^ Allow drop and node removal overriding
+* `pos` - node position
+* `intensity` - TNT explosion measure. larger or equal to 1.0
+^ Should return a list of drops (e.g. {"default:stone"})
+^ Should perform node removal itself. If callback exists in the nodedef
+^ then the TNT code will not destroy this node.
+
+`entitydef.on_blast(luaobj, damage)`
+^ Allow TNT effects on entities to be overridden
+* `luaobj` - LuaEntityRef of the entity
+* `damage` - suggested HP damage value
+^ Should return a list of (bool do_damage, bool do_knockback, table drops)
+* `do_damage` - if true then TNT mod wil damage the entity
+* `do_knockback` - if true then TNT mod will knock the entity away
+* `drops` - a list of drops, e.g. {"wool:red"}
