 .SH DESCRIPTION
+.\" --------------------------------------------------------------------
+.
+This document describes the
+.B groff
+program, the main front-end for the 
+.I groff
+document formatting system.
+.
+The
+.I groff
+program and macro suite is the implementation of a
+.BR roff (@MAN7EXT@)
+system within the free software collection
+.URL http://\:www.gnu.org "GNU" .
+.
+The
+.I groff
+system has all features of the classical
+.IR roff ,
+but adds many extensions.
+.
+.P
+The
+.B groff
+program allows to control the whole
+.I groff
+system by comand line options.
+.
+This is a great simplification in comparison to the classical case (which
+uses pipes only).
+.
+.
+.\" --------------------------------------------------------------------
+.SH OPTIONS
+.\" --------------------------------------------------------------------
+.
+As
+.B groff
+is a wrapper program for
+.B @g@troff
+both programs share a set of options.
+.
+But the
+.B groff
+program has some additional, native options and gives a new meaning to
+some
+.B @g@troff
+options.
+.
+On the other hand, not all
+.B @g@troff
+options can be fed into
+.BR groff .
+.
+.
+.\" --------------------------------------------------------------------
+.SS Native groff Options
+.\" --------------------------------------------------------------------
+.
+The following options either do not exist for
+.B @g@troff
+or are differently interpreted by
+.BR groff .
+.
+.
+.OptDef e
+Preprocess with
+.BR @g@eqn .
+.
+.
+.OptDef g
+Preprocess with
+.BR @g@grn .
+.
+.
+.OptDef G
+Preprocess with
+.BR grap .
+.
+.
+.OptDef h help
+Print a help message.
+.
+.
+.OptDef I "" dir
+Add search directory for
+.BR \%@g@soelim (@MAN1EXT@).
+This option implies the
+.ShortOpt s
+option.
+.
+.
+.OptDef l
+Send the output to a spooler program for printing.
+.
+The command that should be used for this is specified by the
+.B print
+command in the device description file, see
+.BR \%groff_font (@MAN5EXT@).
+If this command is not present, the output is piped into the
+.BR lpr (1)
+program by default.
+.
+See options
+.ShortOpt L
+and
+.ShortOpt X .
+.
+.
+.OptDef L "" arg
+Pass
+.I arg
+to the spooler program.
+Several arguments should be passed with a separate
+.ShortOpt L
+option each.
+.
+Note that
 .B groff
-is a front-end to the groff document formatting system.
-Normally it runs the
+does not prepend
+.ShortOpt\" just a minus sign
+(a minus sign) to
+.I arg
+before passing it to the spooler program.
+.
+.
+.OptDef N
+Don't allow newlines within
+.I eqn
+delimiters.
+.
+This is the same as the
+.ShortOpt N
+option in
+.BR @g@eqn .
+.
+.
+.OptDef p
+Preprocess with
+.BR @g@pic .
+.
+.
+.OptDef P "" "-option"
+.OptDef+ P "" "-option \f[CB]-P\f[] arg"
+Pass
+.I -option
+or
+.I -option arg
+to the postprocessor.
+.
+The option must be specified with the necessary preceding minus
+sign(s)
+.Quoted \*[@-]
+or
+.Quoted \*[@--]
+because groff does not prepend any dashes before passing it to the
+postprocessor.
+.
+For example, to pass a title to the gxditview postprocessor, the shell
+command
+.IP
+.ShellCommand groff -X -P -title -P 'groff it' \f[I]foo\f[]
+.IP
+is equivalent to
+.IP
+.ShellCommand groff -X -Z \f[I]foo\f[] | gxditview -title 'groff it' -
+.
+.
+.OptDef R
+Preprocess with
+.BR @g@refer .
+.
+No mechanism is provided for passing arguments to 
+.B @g@refer
+because most
+.B @g@refer
+options have equivalent language elements that can be specified within
+the document.
+.
+See
+.BR \%@g@refer (@MAN1EXT@)
+for more details.
+.
+.
+.OptDef s
+Preprocess with
+.BR @g@soelim .
+.
+.
+.OptDef S
+Safer mode.
+.
+Pass the
+.ShortOpt S
+option to
+.B @g@pic
+and disable the following
 .B @g@troff
-program and a postprocessor appropriate for the selected
-device.
-Available devices are:
+requests:
+.BR .open ,
+.BR .opena ,
+.BR .pso ,
+.BR .sy ,
+and
+.BR .pi .
+For security reasons, safer mode is enabled by default.
+.
+.
+.OptDef t
+Preprocess with
+.BR @g@tbl .
+.
+.
+.OptDef T "" dev
+Set output device to
+.IR dev .
+The possible values in
+.I groff
+are
+.BR ascii ,
+.BR cp1047 ,
+.BR dvi ,
+.BR html ,
+.BR latin1 ,
+.BR lbp ,
+.BR lj4 ,
+.BR ps ,
+.BR utf8 ,
+.BR X75 ,
+and
+.BR X100 .
+.
+Additionally,
+.B X75-12
+and
+.B X100-12
+are available for documents which use 12\|pt as the base document size.
+.
+The default device is
+.BR @DEVICE@ .
+.
+.
+.OptDef U
+Unsafe mode.
+.
+Reverts to the (old) unsafe behaviour; see option
+.ShortOpt S .
+.
+.
+.OptDef v version
+Output version information of
+.B groff
+and of all programs that are run by it; that is, the given command line
+is parsed in the usual way, passing
+.ShortOpt v
+to all subprograms.
+.
+.
+.OptDef V
+Output the pipeline that would be run by
+.BR groff
+(as a wrapper program), but do not execute it.
+.
+.
+.OptDef X
+Use
+.B gxditview
+instead of using the usual postprocessor to (pre)view a document.
+.
+The printing spooler behavior as outlined with options
+.ShortOpt l
+and
+.ShortOpt L 
+is carried over to 
+.BR \%gxditview (@MAN1EXT@)
+by determining an argument for the
+.B -printCommand
+option of
+.BR \%gxditview (@MAN1EXT@).
+.
+This sets the default
+.B Print
+action and the corresponding menu entry to that value.
+.
+.ShortOpt X
+only produces good results with
+.ShortOpt Tps ,
+.ShortOpt TX75 ,
+.ShortOpt TX75-12 ,
+.ShortOpt TX100 ,
+and
+.ShortOpt TX100-12 .
+.
+The default resolution for previewing
+.ShortOpt Tps
+output is 75\|dpi; this can be changed by passing the
+.ShortOpt resolution
+option to
+.BR gxditview ,
+for example
+.
+.IP
+.ShellCommand groff -X -P-resolution -P100 -man foo.1
+.
+.
+.OptDef z
+Suppress output generated by
+.BR @g@troff .
+Only error messages will be printed.
+.
+.
+.OptDef Z
+Do not postprocess the output of
+.B @g@troff
+that is normally
+called automatically by
+.BR groff .
+This will print the intermediate output to standard output; see
+.BR \%groff_out (@MAN5EXT@).
+.
+.
+.\" --------------------------------------------------------------------
+.SS Tranparent Options
+.\" --------------------------------------------------------------------
+.
+The following options are transparently handed over to the formatter
+program
+.B @g@troff
+that is called by groff subsequently.
+.
+These options are described in more detail in
+.BR @g@troff (@MAN1EXT@).
+.
+.OptDef a
+ascii approximation of output.
+.
+.OptDef b
+backtrace on error or warning.
+.
+.OptDef c
+disable color output.
+.
+.OptDef C
+enable compatibility mode.

+.SH "USING GROFF"
+.\" --------------------------------------------------------------------
+.
+The
+.I groff system
+implements the infrastructure of classical roff; see
+.BR roff (@MAN7EXT@)
+for a survey on how a roff system works in general.
+.
+Due to the front-end programs available within the groff system, using
+.I groff
+is much easier than
+.IR "classical roff" .
+.
+This section gives an overview of the parts that consitute the groff
+system.
+.
+It complements
+.BR roff (@MAN7EXT@)
+with groff-specific features.
+.
+This section can be regarded as a guide to the documentation around
+the groff system.
+.
+.
+.\" --------------------------------------------------------------------
+.SS Front-ends
+.\" --------------------------------------------------------------------
+.
+The
+.B groff
+program is a wrapper around the
+.BR @g@troff (@MAN1EXT@)
+program.
+.
+It allows to specify the preprocessors by command line options and
+automatically runs the postprocessor that is appropriate for the
+selected device.
+.
+Doing so, the sometimes tedious piping mechanism of classical
+.BR roff (@MAN7EXT@)
+can be avoided.
+.
+.P
+The
+.BR grog (@MAN1EXT@)
+program can be used for guessing the correct groff command line to
+format a file.
+.
+.P
+The
+.BR \%groffer (@MAN1EXT@)
+program is an allround-viewer for groff files and man pages.
+.
+.
+.\" --------------------------------------------------------------------
+.SS Preprocessors
+.\" --------------------------------------------------------------------
+.
+The groff preprocessors are reimplementations of the classical
+preprocessors with moderate extensions.
+.
+The preprocessors distributed with the
+.I groff
+package are
+.
 .TP
-.B ps
-For PostScript printers and previewers
+.BR @g@eqn (@MAN1EXT@)
+for mathematical formul\(ae,
 .TP
-.B dvi
-For TeX dvi format.
+.BR @g@grn (@MAN1EXT@)
+for including
+.BR gremlin (1)
+pictures,
 .TP
-.B X75
-For a 75dpi X11 previewer.
+.BR @g@pic (@MAN1EXT@)

 .TP
-.B latin1
-For typewriter-like devices using the ISO Latin-1 (ISO 8859-1) character set.
+.BR @g@tbl (@MAN1EXT@)
+for tables.
+.
+.P
+Besides these, there are some internal preprocessors that are
+automatically run with some devices.
+.
+These aren't visible to the user.
+.
+.
+.\" --------------------------------------------------------------------
+.SS "Macro Packages"
+.\" --------------------------------------------------------------------
+.
+Macro packages can be included by option
+.ShortOpt m .
+.
+The groff system implements and extends all classical macro packages
+in a compatible way and adds some packages of its own.
+.
+Actually, the following macro packages come with
+.IR groff :
+.
 .TP
-.B utf8
-For typewriter-like devices using the Unicode (ISO 10646) character set with
-UTF-8 encoding.
+.B man
+The traditional man page format; see
+.BR \%groff_man (@MAN7EXT@).
+It can be specified on the command line as
+.ShortOpt man
+or
+.ShortOpt m
+.BR man .
+.
+.TP
+.B mandoc
+The general package for man pages; it automatically recognizes
+whether the documents uses the
+.I man
+or the
+.I mdoc
+format and branches to the corresponding macro package.
+.
+It can be specified on the command line as
+.ShortOpt mandoc
+or
+.ShortOpt m
+.BR mandoc .
+.
+.TP
+.B mdoc
+The BSD-style man page format; see
+.BR \%groff_mdoc (@MAN7EXT@).
+It can be specified on the command line as
+.ShortOpt mdoc
+or
+.ShortOpt m
+.BR mdoc .
+.
+.TP
+.B me
+The classical
+.I me
+document format; see
+.BR \%groff_me (@MAN7EXT@).
+It can be specified on the command line as
+.ShortOpt me
+or
+.ShortOpt m
+.BR me .
+.
+.TP
+.B mm
+The classical
+.I mm
+document format; see
+.BR \%groff_mm (@MAN7EXT@).
+It can be specified on the command line as

+.BR mm .
+.
+.TP

+.\" --------------------------------------------------------------------
+.SS "Programming Language"
+.\" --------------------------------------------------------------------
+.
+General concepts common to all roff programming languages are

+.
+.
+.\" --------------------------------------------------------------------
+.SS Formatters
+.\" --------------------------------------------------------------------
+.
+The central roff formatter within the groff system is
+.BR @g@troff (@MAN1EXT@).
+It provides the features of both the classical troff and nroff, as
+well as the groff extensions.
+.
+The command line option
+.ShortOpt C
+switches
+.B @g@troff
+into
+.I "compatibility mode"
+which tries to emulate classical roff as much as possible.
+.
+.P
+There is a shell script
+.BR @g@nroff (@MAN1EXT@)
+that emulates the behavior of classical nroff.
+.
+It tries to automatically select the proper output encoding, according to
+the current locale.
+.
+.P
+The formatter program generates
+.IR "intermediate output" ;
+see
+.BR \%groff_out (@MAN7EXT@).
+.
+.
+.\" --------------------------------------------------------------------
+.SS Devices
+.\" --------------------------------------------------------------------
+.
+In roff, the output targets are called
+.IR devices .
+A device can be a piece of hardware, e.g. a printer, or a software
+file format.
+.
+A device is specified by the option
+.ShortOpt T .
+The groff devices are as follows.
