NAME
       deroff, delatex - remove formatting requests

SYNOPSIS
       deroff [ option ...  ] file ...

       delatex file

DESCRIPTION
       Deroff  reads  each file in sequence and removes all nroff and troff(1)
       requests and non-text  arguments,  backslash  constructions,  and  con‐
       structs of preprocessors such as eqn(1), pic(1), and tbl(1).  Remaining
       text is written on the standard output.	Deroff follows files  included
       by  and	commands; if a file has already been included, a for that file
       is ignored and a terminates execution.  If  no  input  file  is	given,
       deroff reads from standard input.

       The options are

       -w     Output  a	 word list, one `word' (string of letters, digits, and
	      properly embedded ampersands and apostrophes, beginning  with  a
	      letter) per line.	 Other characters are skipped.	Otherwise, the
	      output follows the original, with the deletions mentioned above.

       -_     Like -w, but consider underscores to be alphanumeric rather than
	      punctuation.

       -i     Ignore and requests.

       -ms

       -mm    Remove titles, attachments, etc., as well as ordinary troff con‐
	      structs, from ms(6) or mm documents.

       -ml    Same as -mm, but remove lists as well.

       Delatex does for tex and latex (see tex(1)) files what deroff -wi  does
       for troff files.

BUGS
       These filters are not complete interpreters of troff or tex.  For exam‐
       ple, macro definitions containing cause chaos in deroff when the	 popu‐
       lar delimiters for eqn are in effect.

       Text  inside  macros  is	 emitted  at place of definition, not place of
       call.
