DEROFF(1-BSD)       RISC/os Reference Manual        DEROFF(1-BSD)



NAME
     deroff - remove nroff, troff, tbl and eqn constructs

SYNOPSIS
     deroff [ -w ] [ -k ] [ -m (a e l m s) ] [ file ... ]

DESCRIPTION
     deroff reads each file in sequence and removes all nroff and
     troff command lines, backslash constructions, macro defini-
     tions, eqn constructs (between `.EQ' and `.EN' lines or
     between delimiters), and table descriptions, and writes the
     remainder on the standard output.  deroff follows chains of
     included files (`.so' and `.nx' commands); if a file has
     already been included, a `.so' is ignored and a `.nx' ter-
     minates execution.  If no input file is given, deroff reads
     from the standard input file.

     If the -w flag is given, the output is a word list, one
     `word' (string of letters, digits, and apostrophes, begin-
     ning with a letter; apostrophes are removed) per line, and
     all other characters ignored.  Otherwise, the output follows
     the original, with the deletions mentioned above.

     The -m option may be followed by an m, s, a, e, or l.  The
     -mm option causes the mm macros to be interpreted so that
     only running text is output (i.e., no text from macro
     lines.)  Similarly, the -ms option causes deletion of the ms
     macro commands; the -ma option causes deletion of the man
     macro commands; and the -me option causes deletion of the me
     macro commands.  The -ml option forces the -mm option and
     also causes deletion of lists associated with the mm macros.

     The -k option keeps blocks of text after a `.nf' (no fill)
     command; without this flag, the -m option removes these
     blocks of text.

SEE ALSO
     eqn(1), nroff(1), tbl(1), troff(1).

BUGS
     deroff is not a complete troff interpreter, so it can be
     confused by subtle constructs.  Most errors result in too
     much rather than too little output.
