   grodvi is a driver for groff that produces TeX dvi format.  Normally it
   should be run by groff -Tdvi.  This will run troff -Tdvi; it will also
   input the macros in /usr/share/groff/1.22.3/tmac/dvi.tmac.

   The dvi file generated by grodvi can be printed by any correctly-
   written dvi driver.  The troff drawing primitives are implemented using
   the tpic version 2 specials.  If the driver does not support these, the
   \D commands will not produce any output.

   There is an additional drawing command available:

   \D'R dh dv'
          Draw a rule (solid black rectangle), with one corner at the
          current position, and the diagonally opposite corner at the
          current position +(dh,dv).  Afterwards the current position will
          be at the opposite corner.  This produces a rule in the dvi file
          and so can be printed even with a driver that does not support
          the tpic specials unlike the other \D commands.

   The groff command \X'anything' is translated into the same command in
   the dvi file as would be produced by \special{anything} in TeX;
   anything may not contain a newline.

   For inclusion of EPS image files, -Tdvi loads pspic.tmac automatically,
   providing the PSPIC macro.  Please check groff_tmac(5) for a detailed

   Font files for grodvi can be created from tfm files using tfmtodit(1).
   The font description file should contain the following additional

   internalname name
                 The name of the tfm file (without the .tfm extension) is

   checksum n    The checksum in the tfm file is n.

   designsize n  The designsize in the tfm file is n.

   These are automatically generated by tfmtodit.

   The default color for \m and \M is black.  Currently, the drawing color
   for \D commands is always black, and fill color values are translated
   to gray.

   In troff the \N escape sequence can be used to access characters by
   their position in the corresponding tfm file; all characters in the tfm
   file can be accessed this way.

   By design, the DVI format doesn't care about physical dimensions of the
   output medium.  Instead, grodvi emits the equivalent to TeX's
   \special{papersize=width,length} on the first page; dvips (and possibly
   other DVI drivers) then sets the page size accordingly.  If either the
   page width or length is not positive, no papersize special is output.


   -d     Do not use tpic specials to implement drawing commands.
          Horizontal and vertical lines will be implemented by rules.
          Other drawing commands will be ignored.

   -Fdir  Prepend directory dir/devname to the search path for font and
          device description files; name is the name of the device,
          usually dvi.

   -l     Specify landscape orientation.

          Specify paper dimensions.  This overrides the papersize,
          paperlength, and paperwidth commands in the DESC file; it
          accepts the same arguments as the papersize command (see
          groff_font(5) for details).

   -v     Print the version number.

   -wn    Set the default line thickness to n thousandths of an em.  If
          this option isn't specified, the line thickness defaults to
          0.04 em.


   There are styles called R, I, B, and BI mounted at font positions 1
   to 4.  The fonts are grouped into families T and H having members in
   each of these styles:

          TR     CM Roman (cmr10)
          TI     CM Text Italic (cmti10)
          TB     CM Bold Extended Roman (cmbx10)
          TBI    CM Bold Extended Text Italic (cmbxti10)
          HR     CM Sans Serif (cmss10)
          HI     CM Slanted Sans Serif (cmssi10)
          HB     CM Sans Serif Bold Extended (cmssbx10)
          HBI    CM Slanted Sans Serif Bold Extended (cmssbxo10)

   There are also the following fonts which are not members of a family:

          CW     CM Typewriter Text (cmtt10)
          CWI    CM Italic Typewriter Text (cmitt10)

   Special fonts are MI (cmmi10), S (cmsy10), EX (cmex10), SC (cmtex10,
   only for CW), and, perhaps surprisingly, TR, TI, and CW, due to the
   different font encodings of text fonts.  For italic fonts, CWI is used
   instead of CW.

   Finally, the symbol fonts of the American Mathematical Society are
   available as special fonts SA (msam10) and SB (msbm10).  These two
   fonts are not mounted by default.

   Using the option -mec (which loads the file ec.tmac) provides the EC
   and TC fonts.  The design of the EC family is very similar to that of
   the CM fonts; additionally, they give a much better coverage of groff
   symbols.  Note that ec.tmac must be called before any language-specific
   files; it doesn't take care of hcode values.


          A list of directories in which to search for the devname
          directory in addition to the default ones.  See troff(1) and
          groff_font(5) for more details.

   Dvi files produced by grodvi use a different resolution (57816 units
   per inch) to those produced by TeX.  Incorrectly written drivers which
   assume the resolution used by TeX, rather than using the resolution
   specified in the dvi file will not work with grodvi.

   When using the -d option with boxed tables, vertical and horizontal
   lines can sometimes protrude by one pixel.  This is a consequence of
   the way TeX requires that the heights and widths of rules be rounded.
