DEROFF(CT)               XENIX System V                DEROFF(CT)



     Name
          deroff - Removes nroff/troff, tbl, and eqn constructs.

     Syntax
          deroff [ -w ] [ -mx ] [ files ]

     Description
          deroff reads each of the files in sequence and removes all
          troff(CT) requests, macro calls, backslash constructs,
          eqn(CT) constructs (between .EQ and .EN lines, and between
          delimiters), and tbl(CT) descriptions.  It writes the
          remainder of the file on the standard output.  deroff
          follows chains of included files (.so and .nx troff
          commands).  If a file has already been included, a .so
          naming that file is ignored and a .nx naming that file
          terminates execution.  If no input file is given, deroff
          reads the standard input.

          The -m option may be followed by an m, s, or l.  The
          resulting -mm or -ms option causes the MM or MS macros to be
          interpreted so that only running text is output (i.e., no
          text from macro lines).  The -ml option forces the -mm
          option and also causes deletion of lists associated with the
          MM macros.  This option is used by the diction(CT) command.

          The -w option outputs a word list, one ``word'' per line,
          with all other characters deleted.  Otherwise, the output
          follows the original, with the deletions mentioned above.
          In text, a ``word'' is any string that contains at least two
          letters and is composed of letters, digits, ampersands (&),
          and apostrophes (').  In a macro call, however, a ``word''
          is a string that begins with at least two letters and
          contains a total of at least three letters.  Delimiters are
          any characters other than letters, digits, apostrophes, and
          ampersands.  Trailing apostrophes and ampersands are removed
          from ``words.''

     Notes
          Since deroff is not a complete troff interpreter, it can
          result in too much output.

          The -ml option does not handle nested lists correctly.

          deroff also removes words of two or fewer letters in lines
          that begin with macro calls or troff requests.
