troff2null - convert troff documents to troffcvt internal format

troff2null uses a set of special macros that tell troffcvt how to generate tc2null-specific  output  that
       tc2null uses to recognize NULL structural elements.  These macros do not work in compatibility mode.

                                                                                                   TROFF2NULL(1)

troff2null  converts files written in the troff input language and converts them to the troffcvt internal
       representation.  It works by running the input files through troffcvt and then through tc2null.troff2null understands the usual troffcvt options.  It also understands  the  additional  options  listed
       below:

       -D     Enable debugging output.

       -E     Cause tc2null to echo token information to stderr as tokens are read from troffcvt.

       -n     No execution.  Just show the commands that troff2null would execute to process the document.

       -p     Don't run the postprocessor (tc2null).

       -Ttitle
              Specify  a  title  for  the  document.   This  can  be  used for documents that do not contain any
              recognizable title.  If the document does contain a title, it is overridden.
