NAME
          grodvi - convert groff output to TeX dvi format

     SYNOPSIS
          grodvi [ -dv ] [ -wn ] [ -Fdir ] [ files...  ]

     DESCRIPTION
          grodvi is a driver for groff that produces TeX dvi format.
          Normally it should be run by groff -Tdvi.  This will run
          gtroff -Tdvi; it will also input the macros
          /usr/products/src2/gcc/AIX.d/lib/groff/tmac/tmac.dvi; if the
          input is being preprocessed with geqn it will also input
          /usr/products/src2/gcc/AIX.d/lib/groff/font/devdvi/eqnchar.

          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.

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

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

          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.

          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.

     OPTIONS
          -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.

          -v   Print the version number.

          -wn  Set the default line thickness to n thousandths of an
               em.

          -Fdir
               Search directory dir/devdvi for font and device
               description files.

     FILES
          /usr/products/src2/gcc/AIX.d/lib/groff/font/devdvi/DESC
               Device description file.

          /usr/products/src2/gcc/AIX.d/lib/groff/font/devdvi/ F
               Font description file for font F.

          /usr/products/src2/gcc/AIX.d/lib/groff/tmac/tmac.dvi
               Macros for use with grodvi.

     BUGS
          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.
