deroff(1)
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.
