     DEROFF(1)                                               DEROFF(1)

          deroff - remove nroff, troff, tbl and eqn constructs

          deroff [ -w ] file ...

          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' termi-
          nates 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.

          troff(1), eqn(1), tbl(1)

          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.
