local GLib = lgi.require("GLib", "2.0")

--[[ Explanation

  Some multimedia apps (music players, for example) that uses GLib and related libraries (Gtk,
  GObject, GStreamer, etc...) commonly auto-detects user directories that contains specific
  things like music, videos, pictures and documents. That's nice, but... How is it done?
  Well... Here's the answer:
