At this moment dednat6load.lua can be called in
standalone mode in two ways:

  ./dednat6load.lua -4 somefile.tex
  ./dednat6load.lua -t somefile.tex

The way with "-4" behaves "as dednat4", i.e., "as a true
preprocessor", as explained in the section 2 of the TUGBoat article:
it creates a file "somefile.dnt" with the adequate headers.

The way with "-t" is a low-level version of "-4" that is mainly for
tests and debugging. You don't want to use it.
