-# wtf is hook?
-Hook - Ruby script executed in other script, with context(binding) of parent script.
-
-# Hooks dirs
-For more information you can read scripts/
-* hooks/*/init/ - executed in script after initialization (you can change some variables and other)
-'*' - class like Scene_Title
-* hooks/Window_NameInput/init2 - Window_NameInput init function
-* hooks/Scene_Map/main - main function of Map scene
-* hooks/Main/at_exit - on game exit
-* hooks/Main/start - at game start
-
-# How add custom hooks?
-use RPG::Mod.exec_hooks(path, binding)
-path - path in game directory like "hooks/Scene_Title/init", you can't load something from other place, only from game direcory.
-binding - its a Ruby binding.
-
-# API
-Custom API for mods:
-
-work in progress
-
-# how create mod?
-First what you need it
