/*
rtf2null - RTF-to-nothing translator
Example only: demonstrates a minimal translator. Does nothing,
with the single exception that unknown tokens are echoed. This
allows rtf2null to be used as a "find unknown tokens" filter.
07 Feb 91 Paul DuBois dubois@primate.wisc.edu
07 Feb 91 V1.0. Created.
24 Feb 91 V1.01. Added unknown token class callback.
