-- What the hell is this?
-- Basically helps apps to figure out where to store:
local XDG_STATE_HOME  = HOME .. "/.local/state" -- App related state files
local XDG_DATA_HOME   = HOME .. "/.local/share" -- App related data 
local XDG_CONFIG_HOME = HOME .. "/.config"      -- App related configuration files
local XDG_CACHE_HOME  = HOME .. "/.cache"       -- App related cache files

-- Using these, your $HOME will have less weird directories and files
