.SH DESCRIPTION
.B groff
is a front-end to the groff document formatting system.
Normally it runs the
.B @g@troff
program and a postprocessor appropriate for the selected
device.
Available devices are:
.TP
.B ps
For PostScript printers and previewers
.TP
.B dvi
For TeX dvi format.
.TP
.B X75
For a 75 dpi X11 previewer.
.TP
.B X100
For a 100dpi X11 previewer.
.TP
.B ascii
For typewriter-like devices.
.TP
.B latin1
For typewriter-like devices using the ISO Latin-1 character set.
.TP 
.B lj4
For an HP LaserJet4-compatible (or other PCL5-compatible) printer.
.TP
.B koi8-r
For typewriter-like devices using the russian KOI8-R character set.
.TP
.B html
To produce HTML output.
.LP
The postprocessor to be used for a device is specified by the
.B postpro
command in the device description file.
This can be overridden with the
.B \-X
option.
.LP
The default device is
.BR @DEVICE@ .
It can optionally preprocess with any of
.BR @g@pic ,
.BR @g@eqn ,
.BR @g@tbl ,
.BR @g@refer ,
or
.B @g@soelim.
.LP
Options without an argument can be grouped behind a single
.BR \- .
A filename of
.B \-
denotes the standard input.
.LP
The
.B grog
command can be used to guess the correct groff command to use to
format a file.
.SH OPTIONS
.TP
.B \-h
Print a help message.
.TP
.B \-e
Preprocess with @g@eqn.
.TP
.B \-t
Preprocess with @g@tbl.
.TP
.B \-p
Preprocess with @g@pic.
.TP
.B \-s
Preprocess with @g@soelim.
.TP
.BI \-I dir
This option is as described in
.BR @g@soelim (@MAN1EXT@) .
This option implies the
.B \-s
option.
.TP
.B \-R
Preprocess with @g@refer.
No mechanism is provided for passing arguments to 
.B @g@refer
because most @g@refer options have equivalent commands
which can be included in the file.
See
.BR @g@refer (@MAN1EXT@)
for more details.
.TP
.B \-v
Make programs run by
.B groff
print out their version number.
.TP
.B \-V
Print the pipeline on stdout instead of executing it.
.TP
.B \-z
Suppress output from
.BR @g@troff .
Only error messages will be printed.
.TP
.B \-Z
Do not postprocess the output of
.BR @g@troff .
Normally
.B groff
will automatically run the appropriate postprocessor.
.TP
.BI \-P arg
Pass
.I arg
to the postprocessor.
Each argument should be passed with a separate
.B \-P
option.
Note that
.B groff
does not prepend
.B \-
to
.I arg
before passing it to the postprocessor.
.TP
.B \-l
Send the output to a printer.
The command used for this is specified by the
.B print
command in the device description file.
.TP
.BI \-L arg
Pass
.I arg
to the spooler.
Each argument should be passed with a separate
.B \-L
option.
Note that
.B groff
does not prepend
.B \-
to
.I arg
before passing it to the postprocessor.
.TP
.BI \-T dev
Prepare output for device
.IR dev .
The default device is
.BR @DEVICE@ .
.TP
.B \-X
Preview with
.B gxditview
instead of using the usual postprocessor.
.B Groff
passes
.B gxditview
a
.B -printCommand
option which will make the
.B Print
action do what
.B groff
would have done if the
.B -l
option had been given.
This is unlikely to produce good results except with
.BR \-Tps .
.TP
.B \-N
Don't allow newlines with eqn delimiters.
This is the same as the
.B \-N
option in
.BR @g@eqn .
.TP
.B \-S
Safer mode.  Pass the
.B \-S
option to
.B @g@pic
and use the
.B \%\-msafer
macros with
.BR @g@troff .
(enabled by default)
.TP
.B \-U
Unsafe mode.  Reverts to the old unsafe behaviour.

.B GROFF_COMMAND_PREFIX
If this is set
.IR X ,
then
.B groff
will run
.IB X troff
instead of
.BR @g@troff .
This also applies to
.BR tbl ,
.BR pic ,
.BR eqn ,
.BR refer ,
and
.BR soelim .
It does not apply to
.BR grops ,
.BR grodvi ,
.BR grotty ,
.BR grolj4 ,
.BR grohtml ,
and
.BR gxditview .
.TP
.SM
.B GROFF_TMAC_PATH
A colon separated list of directories in which to search for
macro files.
.TP
.SM
.B GROFF_TYPESETTER
Default device.
.TP
.SM
.B GROFF_FONT_PATH
A colon separated list of directories in which to search for the
.BI dev name
directory.
.TP
.SM
.B PATH
The search path for commands executed by
.BR groff .
.TP
.SM
.B GROFF_TMPDIR
The directory in which temporary files will be created.

The
.BR grops (@MAN1EXT@)
and
.BR @g@refer (@MAN1EXT@)
commands can create temporary files.
