.TH MM 1
.SH NAME
mm \- print out documents formatted with the \s-1MM\s+1 macros
.SH SYNOPSIS
.B mm
[ options ] [ files ]
.SH DESCRIPTION
.I Mm\^
can be used to type out documents using
.IR nroff (1)
and the
.SM MM
text-formatting macro package.
It has options to specify
preprocessing by
.IR tbl (1)
and/or
.IR neqn (1)
and postprocessing by various terminal-oriented output filters.
The proper pipelines and the
required arguments and flags for
.IR nroff (1)
and
.SM MM
are generated, depending on the options selected.
.PP
.I Options\^
for
.I mm\^
are given below.
Any other arguments or flags (e.g.,
.BR \-rC3 )
are passed
to
.IR nroff (1)
or to
.SM MM\*S,
as appropriate.
Such options can occur in any order,
but they must appear before the
.I files\^
arguments.
If no arguments are given,
.I mm\^
prints a list of its options.
.PP
.PD 0
.TP 9
.BI \-T term
Specifies the type of output terminal;
for a list of recognized values for
.IR term ,
type
.BR "help term2" .
If this option is
.I not\^
used,
.I mm\^
will use the value of the shell variable
.SM
.B $TERM
from the environment (see
.IR profile (5)
and
.IR environ (7))
as the value of
.IR term ,
if
.SM
.B $TERM
is set;
otherwise,
.I mm\^
will use
.B 450
as the value of
.IR term .
If several terminal types are specified,
the last one takes precedence.
.TP
.B \-12
Indicates that the document is to be produced in 12-pitch.
May be used when
.SM
.B $TERM
is set to one of
.BR 300 ,
.BR 300s ,
.BR 450 ,
and
.BR 1620 .
(The pitch switch on the
.SM DASI
300 and 300s terminals must be manually
set to
.B 12
if this option is used.)
.TP
.B \-c
Causes
.I mm\^
to invoke
.IR col (1);
note that
.IR col (1)
is invoked automatically by
.I mm\^
unless
.I term\^
is one of
.BR 300 ,
.BR 300s ,
.BR 450 ,
.BR 37 ,
.BR 4000A ,
.BR 382 ,
.BR 4014 ,
.BR tek ,
.BR 1620 ,
and
.BR X .
.TP
.B \-e
Causes
.I mm\^
to invoke
.IR neqn (1);
also causes
.I neqn
to read the
.B /usr/pub/eqnchar
file (see
.IR eqnchar (7)).
.TP
.B \-t
Causes
.I mm\^
to invoke
.IR tbl (1).
.TP
.B \-E
Invokes the
.B \-e
option of
.IR nroff (1).
.TP
.B \-y
Causes
.I mm\^
to use the non-compacted version of the macros (see
.IR mm (7)).
.PD
.PP
As an example (assuming that the shell variable
.SM
.B $TERM
is set in the environment to
.BR 450 ),
the two command lines below are equivalent:
.RS
.PP
mm \|\-t \|\-rC3 \|\-12 \|ghh\(**
.br
tbl \|ghh\(** \|\(bv \|nroff \|\-cm \|\-T450\-12 \|\-h \|\-rC3
.RE
.PP
.I Mm\^
reads the standard input
when
.B \-
is specified
instead of any file names.
(Mentioning other files together with
.B \-
leads to disaster.)\ 
This option allows
.I mm\^
to be used as a filter, e.g.:
.RS
.PP
cat \|dws \|\(bv \|mm \|\-
.RE
.SH HINTS
.PD 0
.TP
1.
.I Mm\^
invokes
.IR nroff (1)
with the
.B \-h
flag.
With this flag,
.IR nroff (1)
assumes that the terminal has tabs set
every 8 character positions.
.TP
2.
Use the
.BI \-o list\^
option of
.IR nroff (1)
to specify ranges of pages to be output.
Note, however, that
.IR mm ,
if invoked with
one or more of the
.BR \-e ,
.BR \-t ,
and
.B \-
options,
.I together\^
with the
.BI \-o list\^
option of
.IR nroff (1)
may cause a harmless ``broken pipe'' diagnostic
if the last page of the document is not specified in
.IR list .
.TP
3.
If you use the
.B \-s
option of
.IR nroff (1)
(to stop between pages of output),
use line-feed (rather than return or new-line)
to restart the output.
The
.B \-s
option of
.IR nroff (1)
does not work with the
.B \-c
option of
.IR mm ,
or if
.I mm\^
automatically invokes
.IR col (1)
(see
.B \-c
option above).
.TP
4.
If you lie to
.I mm\^
about the kind of terminal its output will be printed on,
you'll get (often subtle) garbage;
however, if you are redirecting output into a file, use the
.B \-T37
option, and then use the appropriate terminal filter when you actually print that file.
