.TH DEROFF 1 
.SH NAME
deroff \- remove formatting requests
.SH SYNOPSIS
.B deroff
[ option ... ]
file ...
.SH DESCRIPTION
.I Deroff
reads each file in sequence
and removes all
.I nroff
and
.I troff
command lines, backslash constructions, macro definitions,
.I eqn
constructs
(between `.EQ' and `.EN' lines or between 
delimiters),
.I tbl
table descriptions,
.I pic
constructs,
and
.I refer
references.
Remaining text is written on the standard output.
.I Deroff
follows chains of included files
(`.so' and `.nx' commands);
if a file has already been included, a `.so' is ignored and a `.nx' terminates execution.
If no input file is given,
.I deroff
reads from the standard input file.
.PP
The options are
.TP
.B \-w
Output a word list, one `word' (string of letters, digits, and apostrophes,
beginning with a letter; apostrophes are removed) per line, and all other characters ignored.
Otherwise, the output follows the original, with the deletions mentioned above.
.TP
.B \-i
Ignore `.so' and `.nx' requests.
.TP
.BR \-ms ,\  \-mm
Follow the conventions of
.IR ms (7)
or
.I mm
macros.
.TP
.B \-ml
Follow the conventions of
.I mm
and suppress lists.

troff(1), eqn(1), tbl(1), pic(1), refer(1)
.SH BUGS
.I Deroff
is not a complete
.I troff
interpreter; it can be confused.
In particular, 
.I troff
macro definitions containing `\\$' cause chaos when the popular `$$'
delimiters for
.I eqn
are in effect.
