so if you wan tto use those libraries use xetex instead then (no gain in
using luatex); the objective of the luatex project is to have a regular
opened up tex engine with all under user/macro package control
eventually (when luatex is mostly finished) one can always consider
using libraries (i.e. converting node lists to whatever some library
likes and convert what comes back to node lists) but that is then just
one of the methods and not part of the luatex project
