NAME

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

SYNOPSIS

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

DESCRIPTION

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.

OPTIONS

-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 commands.

NOTES

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.
