       _d_v_i_2_t_t_y converts a TeX DVI-file to a format that is appro-
       priate  for  terminals  and  line printers. The program is
       intended to be used for preliminary proofreading of TeX-ed
       documents.   By default the output is directed to the ter-
       minal, possibly through a pager (depending on how the pro-
       gram was installed), but it can be directed to a file or a
       pipe.

       The output leaves much to be desired, but is still  useful
       if  you  want  to  avoid  walking to the laser printer (or
       whatever) for each iteration of your document.
       Since _d_v_i_2_t_t_y  produces  output  for  terminals  and  line
       printers  the  representation  of  documents  is naturally
       quite primitive.  In principle Font  Changes  are  totally
       ignored,  but  _d_v_i_2_t_t_y  recognizes  a few mathematical and
       special symbols that can be be displayed  on  an  ordinary
       ascii terminal, such as the '+' and '-' symbol.

       If the width of the output text requires more columns than
       fits in one line (c.f. the -w option) it  is  broken  into
       several  lines by _d_v_i_2_t_t_y although they will be printed as
       one line on regular TeX output devices (e.g. laser  print-
       ers).  To show that a broken line is really just one logi-
       cal line an asterisk (``*'') in the  last  position  means
       that  the  logical  line is continued on the next physical
       line output by  _d_v_i_2_t_t_y_.   Such  a  continuation  line  is
       started  with  a  a space and an asterisk in the first two
       columns.

       Options may  be  specified  in  the  environment  variable
       DVI2TTY.  Any option on the command line, conflicting with
       one in the environment, will override  the  one  from  the
       environment.

       OOppttiioonnss::


       --oo ffiillee
              Write output to file ``file''.

       --pp lliisstt
              Print  the  pages chosen by list.  Numbers refer to
              TeX-page numbers (known as \count0).  An example of
              format for list is ``1,3:6,8'' to choose pages 1, 3
              through 6 and 8.   Negative  numbers  can  be  used
              exactly  as  in  TeX,  e g -1 comes before -4 as in

              ``-p-1:-4,17''.

       --PP lliisstt
              Like -p except  that  page  numbers  refer  to  the
              sequential  ordering  of the pages in the dvi-file.
              Negative numbers don't make a lot of sense  here...

       --ww nn   Specify  terminal  width  _n_.   Legal  range 16-132.
              Default is 80. If your terminal has the ability  to
              display  in  132 columns it might be a good idea to
              use -w132 and toggle the terminal into this mode as
              output will probably look somewhat better.

       --vv     Specify  height  of  lines.  Default  value 450000.
              Allows to adjust linespacing.

       --qq     Don't pipe the output through a pager.  This may be
              the default on some systems (depending on the whims
              of the person installing the program).

       --ee nn   This option can be used to  influence  the  spacing
              between words.  With a negative value the number of
              spaces between words becomes less, with a  positive
              value it becomes more.  -e-11 seems to worked well.

       --ff     Pipe through a pager, $PAGER if defined,  or  what-
              ever  the  installer  of  the  program  compiled in
              (often ``more''). This may be the default,  but  it
              is  still  okay  to redirect output with ``>'', the
              pager will not be used if output is not going to  a
              terminal.

       --FF     Specify  the  pager program to be used.  This over-
              rides the $PAGER and the default pager.

       --FFpprroogg Use ``prog'' as program to pipe output into. Can be
              used to choose an alternate pager (e g ``-Fless'').

       --tt     \tt fonts were used (instead of cm) to produce  dvi
              file.  (screen.sty  is  a powerfull mean to do that
              with LaTeX).

       --aa     Dvi2tty normally tries to output  accented  charac-
              ters.  With  the -a option, accented characters are
              output without the accent sign.

       --ll     Mark page breaks with  the  two-character  sequence
              ``^L''.  The  default  is to mark them with a form-
              feed character.

       --uu     Don't make any attempts to find  special  Scandina-
              vian  characters.   If  such  characters are in the
              text they will map to ``a''  and  ``o''.   This  is
              probably  the  default outside of Scandinavia. (The

              installer makes this decision when  the program  is
              installed.)

       --ss     Try  to  find  the  special Scandinavian characters
              that on most  (?)   terminals  in  Scandinavia  are
              mapped to ``{|}[\]''.  This can be the default, and
              output from  files  not  containing  these  special
              characters  will  be  identical  regardless of this
              option.

FFIILLEESS
       /usr/ucb/more      probably the default pager.

EENNVVIIRROONNMMEENNTT
       PAGER              the pager to use.
       DVI2TTY               can  be  set  to  hold  command-line
       options.

       Blanks  between  words  get  lost quite easy. This is less
       likely if you are using a wider output  than  the  default
       80.

       Only one file may be specified on the command line.
