-- Textures:
-- Mods should prefix their textures with modname_, eg. given the mod
-- name "foomod", a texture could be called "foomod_superfurnace.png"

-- Global functions:
-- minetest.register_entity(name, prototype_table)
-- minetest.register_tool(name, {lots of stuff})
-- minetest.register_node(name, {lots of stuff})
-- minetest.register_craft({output=item, recipe={...})

-- Global objects:
-- minetest.env - environment reference
--
-- Global tables:
-- minetest.registered_entities
-- ^ List of registered entity prototypes, indexed by name
-- minetest.object_refs
-- ^ List of object references, indexed by active object id
-- minetest.luaentities
-- ^ List of lua entities, indexed by active object id
--
-- EnvRef is basically ServerEnvironment and ServerMap combined.
-- EnvRef methods:
-- - add_node(pos, content); pos={x=num, y=num, z=num}
--   TODO: content -> MapNode as described below
--
-- ObjectRef is basically ServerActiveObject.
-- ObjectRef methods:
-- - remove(): remove object (after returning from Lua)
-- - getpos(): returns {x=num, y=num, z=num}
-- - setpos(pos); pos={x=num, y=num, z=num}
-- - moveto(pos, continuous=false): interpolated move
-- - add_to_inventory(itemstring): add an item to object inventory
--
-- Registered entities:
-- - Functions receive a "luaentity" as self:
--   - It has the member .object, which is an ObjectRef pointing to the object
--   - The original prototype stuff is visible directly via a metatable
--
-- MapNode representation:
-- {name="name", param1=num, param2=num}
