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

SYNOPSIS
       deroff [ -w ] file ...

DESCRIPTION
       Deroff  reads  each  file  in  sequence and removes all nroff and troff command lines, backslash constructions, macro definitions, eqn con-
       structs (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'
       terminates 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, beginning with a letter;  apos-
       trophes	are removed) per line, and all other characters ignored.  Otherwise, the output follows the original, with the deletions mentioned
       above.

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