SH SYNOPSIS
B deroff
[
I option ...

I file ...
PP
B delatex
I file
SH DESCRIPTION
I Deroff
reads each file in sequence
and removes all
I nroff
and
IR troff (1)
requests and non-text arguments, backslash constructions,
and constructs of preprocessors such as
IR eqn (1),
IR pic (1),
and
IR tbl (1).
Remaining text is written on the standard output.
I 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,
I deroff
reads from standard input.
PP
The options are
TP
B -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.
TP
B -_
Like
BR -w ,
but consider underscores to be alphanumeric rather than punctuation.
TP
B -i
Ignore
L .so
and
L .nx
requests.
TP
BR -ms
PD0
TP
B -mm
Remove titles, attachments, etc., as well as ordinary
IR troff
constructs, from
IR ms (6)
or
I mm
documents.
PD
TP
B -ml
Same as
BR -mm ,
but remove lists as well.
PP
I Delatex
does for
I tex
and
I latex
(see
IR tex (1))
files what
B deroff -wi
does for
I troff
files.

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