           Files of this format are produced by routines described in
           _p_l_o_t(3X) and are interpreted for various devices by commands
           described in _t_p_l_o_t(1G).  A graphics file is a stream of
           plotting instructions.  Each instruction consists of an
           ASCII letter usually followed by bytes of binary
           information.  The instructions are executed in order.  A
           point is designated by four bytes representing the xxxx and yyyy
           values; each value is a signed integer.  The last designated
           point in an llll,,,, mmmm,,,, nnnn,,,, or pppp instruction becomes the ``current
           point'' for the next instruction.

           Each of the following descriptions begins with the name of
           the corresponding routine in _p_l_o_t(3X).

           mmmm  move:  The next four bytes give a new current point.

           nnnn  cont:  Draw a line from the current point to the point
              given by the next four bytes.  See _t_p_l_o_t(1G).

           pppp  point:  Plot the point given by the next four bytes.

           llll  line:  Draw a line from the point given by the next four
              bytes to the point given by the following four bytes.

           tttt  label:  Place the following ASCII string so that its
              first character falls on the current point.  The string
              is terminated by a new-line.

           eeee  erase:  Start another frame of output.

           ffff  linemod:  Take the following string, up to a new-line, as
              the style for drawing further lines.  The styles are
              ``dotted'', ``solid'', ``longdashed'', ``shortdashed'',
              and ``dotdashed''.  Effective only for the ----TTTT4444000011114444 and
              ----TTTTvvvveeeerrrr options of _t_p_l_o_t(1G) (Tektronix 4014 terminal and
              Versatec plotter).

           ssss  space:  The next four bytes give the lower left corner of
              the plotting area; the following four give the upper
              right corner.  The plot will be magnified or reduced to
              fit the device as closely as possible.

           Space settings that exactly fill the plotting area with
           unity scaling appear below for devices supported by the
           filters of _t_p_l_o_t(1G).  The upper limit is just outside the
           plotting area.  In every case the plotting area is taken to
           be square; points outside may be displayable on devices
           whose face is not square.
