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 con‐
structs of preprocessors such as eqn(1), pic(1), and tbl(1). Remaining
text is written on the standard output. Deroff follows files included
by and commands; if a file has already been included, a for that file
is ignored and a 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 and requests.
-ms
-mm Remove titles, attachments, etc., as well as ordinary troff con‐
structs, 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.

BUGS
These filters are not complete interpreters of troff or tex. For exam‐
ple, macro definitions containing cause chaos in deroff when the popu‐
lar delimiters for eqn are in effect.
Text inside macros is emitted at place of definition, not place of
call.
