--- 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 stack of items in Lua table format.
--- eg. {name="default:dirt", count=1, wear=0, metadata=""} 
---     ^ a single dirt node
--- eg. {name="default:pick_wood", count=1, wear=21323, metadata=""}
---     ^ a wooden pick about 1/3 weared out
--- eg. {name="default:apple", count=1, wear=0, metadata=""}
---     ^ an apple.
---
--- Any time an item must be passed to a function, it can be an
--- ItemStack (see below), an itemstring or a table in the above format.
---

--- Special groups:

--- - level: Can be used to give an additional sense of progression in the game.
