NAME
       dvi2tty - preview a TeX DVI-file on an ordinary ascii terminal

SYNOPSIS
       dvi2tty [ options ] dvi-file

DESCRIPTION
       dvi2tty  converts  a  TeX  DVI-file to a format that is appropriate 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 terminal, possibly through a pager  (depending  on  how
       the program 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  dvi2tty produces output for terminals and line printers the rep-
       resentation of documents is naturally quite  primitive.   In  principle
       Font  Changes  are totally ignored, but dvi2tty recognizes a few mathe-
       matical 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  dvi2tty
       although they will be printed as one line on regular TeX output devices
       (e.g. laser printers). To show that a broken line is  really  just  one
       logical  line  an  asterisk (``*'') in the last position means that the
       logical line is continued on the next physical line output by  dvi2tty.
       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  op-
       tion on the command line, conflicting with one in the environment, will
       override the one from the environment.

       Options:

       -o file
              Write output to file ``file''.

       -p list
              Print the pages chosen by list.  Numbers refer to TeX-page  num-
              bers  (known  as  \count0).   An  example  of format for list is
              ``1,3:6,8'' to choose pages 1, 3 through 6 and 8.  Negative num-
              bers can be used exactly as in TeX, e g -1 comes before -4 as in
              ``-p-1:-4,17''.

       -P list
              Like -p except that page numbers refer to the sequential  order-
              ing of the pages in the dvi-file.  Negative numbers don't make a
              lot of sense here...

       -w n   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.

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

       -q     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).

       -e n   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.

       -f     Pipe  through  a  pager,  $PAGER if defined, or whatever the in-
              staller 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.

       -F     Specify the pager program to be used.  This overrides the $PAGER
              and the default pager.

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

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

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

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

       -c     Do not attempt to translate any  characters  (like  the  Scandi-
              navion/latin1 mode) except when running in tt-font.

       -u     Toggle  option to process certain latin1 characters. Use this if
              your output devices supports latin1 cahracters.  Note  this  may
              interfere with -s. Best not to use -u and -s together.

       -s     Toggle  option  to  process  the special Scandinavian characters
              that on  most  (?)   terminals  in  Scandinavia  are  mapped  to
              ``{|}[\]''.  Note this may interfere with -u. Best not to use -u
              and -s together.

       -J     Auto detect NTT JTeX, ASCII pTeX, and upTeX dvi format.

       -N     Display NTT JTeX dvi.

       -A     Display ASCII pTeX dvi.

       -U     Display upTeX dvi.

       -Eenc  Set output Japanese encoding. The enc argument  'e',  's',  'j',
              and  'u'  denotes EUC-JP, Shift_JIS, ISO-2022-JP, and UTF-8, re-
              spectively.

       -bdelim
              Print the name of fonts when switching to it  (and  ending  it).
              The delim argument is used to delimit the fontname.

FILES
       /bin/more      probably the default pager.

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

BUGS
       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.
