       groff is a front-end to the groff document formatting system.  Normally
       it runs the troff program and a postprocessor appropriate for the
       selected device.  Available devices are:

       ps     For PostScript printers and previewers

       dvi    For TeX dvi format

       X75    For a 75 dpi X11 previewer

       X100   For a 100dpi X11 previewer

       ascii  For typewriter-like devices

       latin1 For typewriter-like devices using the ISO Latin-1 character set.

       The postprocessor to be used for a device is specified by the postpro
       command in the device description file.  This can be overridden with
       the -X option.

       The default device is ps.  It can optionally preprocess with any of
       pic, eqn, tbl, refer, or soelim.

       Options without an argument can be grouped behind a single -.  A
       filename of - denotes the standard input.

       The grog command can be used to guess the correct groff command to use
       to format a file.

       -h     Print a help message.

       -e     Preprocess with eqn.

       -t     Preprocess with tbl.

       -p     Preprocess with pic.

       -s     Preprocess with soelim.

       -R     Preprocess with refer.  No mechanism is provided for passing
              arguments to refer because most refer options have equivalent
              commands which can be included in the file.  See refer(1) for
              more details.

       -v     Make programs run by groff print out their version number.

       -V     Print the pipeline on stdout instead of executing it.

       -z     Suppress output from troff.  Only error messages will be

       -Z     Do not postprocess the output of troff.  Normally groff will
              automatically run the appropriate postprocessor.

       -Parg  Pass arg to the postprocessor.  Each argument should be passed
              with a separate -P option.  Note that groff does not prepend -
              to arg before passing it to the postprocessor.

       -l     Send the output to a printer.  The command used for this is
              specified by the print command in the device description file.

       -Larg  Pass arg to the spooler.  Each argument should be passed with a
              separate -L option.  Note that groff does not prepend - to arg
              before passing it to the postprocessor.

       -Tdev  Prepare output for device dev.  The default device is ps.

       -X     Preview with gxditview instead of using the usual postprocessor.
              Groff passes gxditview a -printCommand option which will make
              the Print action do what groff would have done if the -l option
              had been given.  This is unlikely to produce good results except
              with -Tps.

       -N     Don't allow newlines with eqn delimiters.  This is the same as
              the -N option in eqn.

       -S     Safer mode.  Pass the -S option to pic and use the -msafer
              macros with troff.

       -nnum  These are as described in troff(1).

              If this is set X, then groff will run Xtroff instead of troff.
              This also applies to tbl, pic, eqn, refer and soelim.  It does
              not apply to grops, grodvi, grotty and gxditview.

              A colon separated list of directories in which to search for
              macro files.

              Default device.

              A colon separated list of directories in which to search for the
              devname directory.

       PATH   The search path for commands executed by groff.

              The directory in which temporary files will be created.  If this
              is not set and TMPDIR is set, temporary files will be created in
              that directory.  Otherwise temporary files will be created in
              /tmp.  The grops(1) and refer(1) commands can create temporary

              Device description file for device name.

              Font file for font F of device name.
