Which modules to import?

What a help you guys are :)

What I've found is that the pub modules don't need to be imported. Revised list:

Framework BRL.glMax2D

Import BRL.AppStub
Import BRL.Audio
Import BRL.BASIC
Import BRL.Blitz
Import BRL.BlitzGL
Import BRL.EndianStream
Import BRL.FileSystem
Import BRL.Font
Import BRL.FreeAudioAudio
Import BRL.FreeTypeFont
Import BRL.Keycodes
Import BRL.Math
Import BRL.Max2D
Import BRL.OggLoader
Import BRL.Pixmap
Import BRL.PNGLoader
Import BRL.Random
Import BRL.Retro
Import BRL.StandardIO
Import BRL.Stream
Import BRL.System
Import BRL.WavLoader

Which of these are imported automatically?
