.TH MN 7 "News Version B2.10.3"
.SH NAME
mn \- text formatting macros for the news documentation
.SH SYNOPSIS
.B "nroff  \-mn"
[ options ]  file  ...
.br
.B "troff  \-mn"
[ options ]  file  ...
.SH DESCRIPTION
.PP
This package of
.IR nroff (1)
and
.IR troff (1)
macro definitions provides a formatting facility
which may be used to run off the formatted news documents.
When reverse line motions are needed,
filter the output through
.IR col (1).
.PP
All \-mn macros,
diversions,
string registers,
and number registers are defined below.
Many
.I nroff
and
.I troff
requests are unsafe in conjunction with this package.
However,
the requests below may be used with impunity:
.LP
.ta 5n 12n
.nf
	.bp	begin new page
	.br	break output line
	.sp \f2n\fP	insert \f2n\fP spacing lines
	.ce \f2n\fP	center next \f2n\fP lines
	.ls \f2n\fP	line spacing: \f2n\fP=1 single, \f2n\fP=2 double space
	.na	no alignment of right margin
.fi
.PP
Font and point size changes with \ef and \es are also allowed;
for example,
\&``\ef2word\efR'' will italicize \f2word.\fP
Output of the
.IR tbl (1),
.IR eqn (1),
and
.IR refer (1)
preprocessors for equations,
tables,
and references is acceptable as input.
.SH FILES
/usr/lib/tmac/tmac.n
.SH "SEE ALSO"
eqn(1), refer(1), tbl(1), troff(1)
.SH WARNINGS
.PP
If you do not set the string register ``.f'' to the file name,
you will only be told the line number on which any errors occur.
If you define this string to be the file name,
you will get the file name,
too.
This is useful when dealing with a document
split up into many files.
.PP
This package is not now intended for uses
other than with the news documentation.
.PP
Bug reports are always welcome;
please send them to the author.
(Include a sample of the input;
this helps track down the bug.)

.SH REQUESTS
.PP
In the
.I Note
column,
.I b
means the request causes a break,
and
.I i
means the macro,
number register,
string register,
or diversion is internal and should not be used for anything.
In the
.I "What It Is"
column,
.IR div " means " diversion ,
.IR mac " means " macro ,
.IR num " means " "number register" ,
and
.IR str " means " "string register" .
In the
.I "Initial Value"
column,
a hyphen means no initial value is used,
anything else is the initial value,
and if two values are given,
the first is for
.I nroff
and the second for
.IR troff .
