tc2null(1) diagnostic tool for troffcvt output


tc2null [ options ] file ... ]


tc2null is a postprocessor for troffcvt which tests the correctness of troffcvt output. tc2null also serves as a basis on which other troffcvt postprocessors can be built. It's usually invoked by running the troffcvt front end troff2null .

tc2null understands the following options:

Enable debugging output.
Cause tc2null to echo token information to stderr as tokens are read from troffcvt.
-T title
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.

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