       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 nam-
       ing 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  asso-
                ciated 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.  Other-
                wise, the output follows the original, with the deletions men-
                tioned 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 com-

       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.
