NAME

       deroff - remove nroff, tbl, and neqn constructs

SYNOPSIS

       x] [file ...]

DESCRIPTION

       reads  each file in sequence and removes all requests, macro calls, backslash constructs, constructs (between and lines, and between delim-
       iters -- see neqn(1)), and descriptions (see tbl(1)), replacing them with white space (blanks and blank lines), and writes the remainder of
       the  file  on the standard output.  follows chains of included files and formatter commands); if a file has already been included, a naming
       that file is ignored and a naming that file terminates execution.  If no input file is given, reads the standard input.

       The option can be followed by an or The option causes the macros be interpreted such that only running text is output  (that  is,  no  text
       from macro lines).  The option forces the option and also causes deletion of lists associated with the macros.

       If the 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 multi-byte character string or 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 multi-byte char-
       acter string or a string that begins with at least two letters and contains a total of at least three letters.  Delimiters are any  charac-
       ters other than letters, digits, apostrophes, and ampersands.  Trailing apostrophes and ampersands are removed from ``words.''

       If the option is specified, ignores the and commands.

EXTERNAL INFLUENCES

   Environment Variables
       determines  the	interpretation	of text and filenames as single and/or multi-byte characters.  Note that multi-byte punctuation characters
       are not recognized when using the option.

       determines the language in which messages are displayed.

       If or is not specified in the environment or is set to the empty string, the value of is used as a default for each  unspecified  or  empty
       variable.  If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of

       If  any	internationalization  variable	contains an invalid setting, behaves as if all internationalization variables are set to "C".  See
       environ(5).

   International Code Set Support
       Single- and multi-byte character code sets are supported.

WARNINGS

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

       The option does not handle nested lists correctly.
