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


     deroff [ -m [m | s | l] ] [-w] [-i] [ filename...]


     deroff reads each of the filenames in sequence  and  removes
     all  troff(1)  requests,  macro calls, backslash constructs,
     eqn(1) constructs (between .EQ and .EN  lines,  and  between
     delimiters), and tbl(1) descriptions, perhaps replacing them
     with white space (blanks and blank lines),  and  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.


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

     -w    If the -w option is given, the output is 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.''

     -i    The  -i option causes  deroff to ignore  .so and   .nx

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

     The -ml option does not handle nested lists correctly.
