-- default (Minetest 0.4 mod)
-- Most default stuff

-- Quick documentation about the API
-- =================================
--
-- Helper functions defined by builtin.lua:
-- dump2(obj, name="_", dumped={})
-- dump(obj, dumped={})
--
-- Mod load path
-- -------------
-- Generic:
-- $path_data/mods/
-- $path_userdata/usermods/
-- $mapdir/worldmods/
--
-- On a run-in-place version (eg. the distributed windows version):
-- minetest-0.4.x/data/mods/
-- minetest-0.4.x/usermods/
-- minetest-0.4.x/world/worldmods/
--
-- On an installed version on linux:
-- /usr/share/minetest/mods/
-- ~/.minetest/usermods
-- ~/.minetest/world/worldmods
--
-- Naming convention for registered textual names
-- ----------------------------------------------
-- "modname:<whatever>" (<whatever> can have characters a-zA-Z0-9_)
--
-- This is to prevent conflicting names from corrupting maps and is
-- enforced by the mod loader.
--
-- Example: mod "experimental", ideal item/node/entity name "tnt":
--          -> the name should be "experimental:tnt".
--
-- Enforcement can be overridden by prefixing the name with ":". This can
-- be used for overriding the registrations of some other mod.
--
-- Example: Any mod can redefine experimental:tnt by using the name
--          ":experimental:tnt" when registering it.
-- (also that mods is required to have "experimental" as a dependency)
--
-- The legacy mod uses ":" for maintaining backwards compatibility.
--
-- Textures
-- --------
-- Mods should generally prefix their textures with modname_, eg. given
-- the mod name "foomod", a texture could be called "default_foomod_superfurnace.png"
--
-- This is not crucial and a conflicting name will not corrupt maps.
--
-- Representations of simple things
-- --------------------------------
--
-- MapNode representation:
-- {name="name", param1=num, param2=num}
--
-- param1 and param2 are 8 bit and 4 bit integers, respectively. They
-- are reserved for certain automated functions. If you don't use these
-- functions, you can use them to store arbitrary values.
--
-- param1 is reserved for the engine when:
--   paramtype != "none"
-- param2 is reserved for the engine when any of these are used:
--   liquidtype == "flowing"
--   drawtype == "flowingliquid"
--   drawtype == "torchlike"
--   drawtype == "signlike"
--
-- Position representation:
-- {x=num, y=num, z=num}
--
-- stackstring/itemstring: A stack of items in serialized format.
-- eg. 'node "default:dirt" 5'
-- eg. 'tool "default:pick_wood" 21323'
-- eg. 'craft "default:apple" 2'
--
-- item: A single item in Lua table format.
-- eg. {type="node", name="default:dirt"} 
--     ^ a single dirt node
-- eg. {type="tool", name="default:pick_wood", wear=21323}
--     ^ a wooden pick about 1/3 weared out
-- eg. {type="craft", name="default:apple"}
--     ^ an apple.
