-- Version 3.0
-- Changelog:
-- 02.10.2014 * Some more improvements for inspect-tool. Added craft-guide.
-- 01.10.2014 * Added inspect-tool.
-- 12.01.2013 * If digging the node was unsuccessful, then the replacement will now fail
-- (instead of destroying the old node with its metadata; i.e. chests with content)
-- 20.11.2013 * if the server version is new enough, minetest.is_protected is used
-- in order to check if the replacement is allowed
-- 24.04.2013 * param1 and param2 are now stored
-- * hold sneak + right click to store new pattern
-- * right click: place one of the itmes
-- * receipe changed
-- * inventory image added
-- adds a function to check ownership of a node; taken from VanessaEs homedecor mod
dofile(minetest.get_modpath("replacer").."/check_owner.lua");

-- adds a tool for inspecting nodes and entities
