We've disabled the low level primitives + so that third party modules can not spoil the game (this was already the case in \MKII). + \StopItem + \StartItem + Eventually most management tasks will move from \TEX\ to \LUA, but we keep in pace with + \LUATEX\ development and don't push things to the limit. + \StopItem +\StopItems + +\StartItems{where we will end up} + \StartItem + Eventually we will have a more layered macro package so that one can make specialized + versions. + \StopItem + \StartItem + In addition to the regular \TEX\ interface there will be a \LUA\ interface.
