DEROFF 1
NAME
deroff, delatex - remove formatting requests
SYNOPSIS
deroff [
option ... ]
file ...
delatex file
DESCRIPTION
Deroff reads each file in sequence
and removes all
nroff and
troff (1) requests and non-text arguments, backslash constructions,
and constructs of preprocessors such as
eqn (1), pic (1), and
tbl (1). Remaining text is written on the standard output.
Deroff follows files included by
.L .so
and
.L .nx
commands;
if a file has already been included, a
.L .so
for that file is ignored and a
.L .nx
terminates execution.
If no input file is given,
deroff reads from standard input.
The options are
-w Output a word list, one `word' (string of letters, digits, and
properly embedded ampersands and apostrophes,
beginning with a letter) per line.
Other characters are skipped.
Otherwise, the output follows the original, with the deletions mentioned above.
-_ Like
-w , but consider underscores to be alphanumeric rather than punctuation.
-i Ignore
.L .so
and
.L .nx
requests.
-ms
0
-mm Remove titles, attachments, etc., as well as ordinary
troff constructs, from
ms (6) or
mm documents.
-ml Same as
-mm , but remove lists as well.
Delatex does for
tex and
latex (see
tex (1)) files what
deroff -wi does for
troff files.

troff (1), tex (1), spell (1) BUGS
These filters are not complete interpreters of
troff or
tex . For example, macro definitions containing
.L \e$
cause chaos in
deroff when the popular
.L $$
delimiters for
eqn are in effect.
Text inside macros is emitted at place of
definition, not place of call.
