.SH DESCRIPTION
The groff mm macros are intended to be compatible with the DWB mm macros
with the following limitations:
.TP
.B \(bu
no letter macros implemented (yet).
.TP
.B \(bu
no Bell Labs localisms implemented.
.TP
.B \(bu
the macros OK and PM is not implemented.
.TP
.B \(bu
groff mm does not support cut marks
.LP
\fBmgm\fP is intended to be international. Therefore it is 
possible to write short national macrofiles which change all
english text to the preferred language. Use \fBmgmse\fP as an example.
.LP
Groff mm has several extensions:
.TP
.B "1C [1]"
Begin one column processing. An \fB1\fP as argmunet disabled the page-break.
.TP
.B "APP name text"
Begin an appendix with name \fIname\fP. Automatic naming occurs if
\fIname\fP is "". The appendixes starts with \fBA\fP if auto is used.
An new page is ejected, and a header is also produced if the number
variable \fBAph\fP is non-zero. This is the default.
The appendix always appear in the 'List of contents' with correct
pagenumber. The name \fIAPPENDIX\fP can be changed by setting
the string \fBApp\fP to the desired text.
.TP
.B "APPSK name pages text"
Same as \fB.APP\fP, but the pagenr is incremented with \fIpages\fP.
This is used when diagrams or other non-formatted documents are
included as appendixes.
.TP
.B B1
Begin box (as the ms macro)
Draws a box around the text.
.TP
.B B2
End box. Finish the box.
.TP
.B BVL
Start of 
broken variable-item list.
As VL but text begins always at the next line
.TP
.B "COVER [arg]"
\&\fBCOVER\fP begins a coversheet definition. It is important
that \fB.COVER\fP appears before any normal text.
\&\fB.COVER\fP uses \fIarg\fP to build the filename 
/usr/lib/groff/tmac/mm/\fIarg\fP.cov. Therefore it is possible to create unlimited
types of coversheets.
\fIms.cov\fP is supposed to look like the \fBms\fP coversheet.
\&\fB.COVER\fP requires a \fB.COVEND\fP at the end of the coverdefinition.
Always use this order of the covermacros:
.nf
\&.COVER
\&.TL
\&.AF
\&.AU
\&.AT
\&.AS
\&.AE
\&.COVEND
.fi
However, only \fB.TL\fP and \fB.AU\fP are required.
.TP
.B COVEND
This finish the cover description and prints the cover-page.
It is defined in the cover file.
.TP
.B "GETHN refname [varname]"
Includes the headernumber where the corresponding \fBSETR\fP \fIrefname\fP
was placed. Will be X.X.X. in pass 1. See \fBINITR\fP.
If varname is used, \fBGETHN\fP sets the stringvariable \fIvarname\fP to the 
headernumber.
.TP
.B "GETPN refname [varname]"
Includes the pagenumber where the corresponding \fBSETR\fP \fIrefname\fP
was placed. Will be 9999 in pass 1. See \fBINITR\fP.
If varname is used, \fBGETPN\fP sets the stringvariable \fIvarname\fP
to the pagenumber.
.TP
.B "GETR refname"
Combines \fBGETHN\fP and \fBGETPN\fP with the text 'chapter' and ', page'.
The string \fIQrf\fP contains the text for reference:
.ti +.5i
\&.ds Qrf See chapter \e\e*[Qrfh], page \e\e*[Qrfp].
.br
\fIQrf\fP may be changed to support other languages.
Strings \fIQrfh\fP and \fIQrfp\fP are set by \fBGETR\fP
and contains the page and headernumber.
.TP
.B "GETST refname [varname]"
Includes the string saved with the second argument to \fB.SETR\fP.
Will be dummystring in pass 1.
If varname is used, \fBGETST\fP sets the stringvariable \fIvarname\fP to the 
saved string. See \fBINITR\fP.
.TP
.B "INITR filename"
Initialize the refencemacros. References will be written to
\fIfilename.tmp\fP and \fIfilename.qrf\fP. Requires two passes with groff.
The first looks for references and the second includes them.
\fBINITR\fP can be used several times, but it is only the first
occurrence of \fBINITR\fP that is active.
See also \fBSETR\fP, \fBGETPN\fP and \fBGETHN\fP.
.TP
.B "MC column-size [column-separation] "
Begin multiple columns. Return to normal with 1C.
.TP
.B "MT [arg [addressee]]"
Memorandum type.
The \fIarg\fP is part of a filename in \fI/usr/lib/groff/tmac/mm/*.MT\fP.
Memorandum type 0 thru 5 are supported, including \fI"string"\fP.
\fIAddresse\fP just sets a variable, used in the AT&T macros.
.TP
.B "MOVE y-pos [x-pos [line-length]]"
Move to a position, pageoffset set to \fIx-pos\fP.
If \fIline-length\fP is not given, the difference between
current and new pageoffset is used.
Use \fBPGFORM\fP without arguments to return to normal.
.TP
.B "MULB cw1 space1 [cw2 space2 [cw3 ...]]"
Begin a special multi-column mode. Every columns width must be specified.
Also the space between the columns must be specified. The last column
does not need any space-definition. MULB starts a diversion and MULE
ends the diversion and prints the columns.
The unit for width and space is 'n', but MULB accepts all 
normal unitspecifications like 'c' and 'i'.
MULB operates in a separate environment.
.TP
.B "MULN"
Begin the next column. This is the only way to switch column.
.TP
.B "MULE"
End the multi-column mode and print the columns.
.TP
.B "PGFORM [linelength [pagelength [pageoffset [1]]]]"
Sets linelength, pagelength and/or pageoffset.
This macro can be used for special formatting, like letterheads
and other.
\fBPGFORM\fP can be used without arguments 
to reset everything after a \fBMOVE\fP.
A line-break is done unless the fourth argument is given. 
This can be used to avoid the pagenumber on the first page while setting
new width and length.
.TP
.B PGNH
No header is printed on the next page. Used to get rid off
the header in letters or other special texts
This macro must be used before any text to inhibit the pageheader
on the first page.
.TP
.B "SETR refname [string]"
Remember the current header and page-number as refname.
Saves \fIstring\fP if \fIstring\fP is defined. \fIstring\fP is retrieved
with \fB.GETST\fP.
See \fBINITR\fP.
.TP
.B TAB
reset tabs to every 5n. Normally used to reset any previous tabpositions.
.TP
.B VERBON [flag [pointsize [font]]]
Begin verbatim output using courier font.
Usually for printing programs.
All character has equal width.
The pointsize can be changed with
the second argument. By specifying the font-argument
it is possible to use another font instead of courier.
\fIflag\fP control several special features.
It contains the sum of all wanted features.
.in +.5i
