DVItype output example
----------------------

  As an example of the output from DVItype (see section above), here is
its (abridged) translation of the `story.dvi' resulting from running
the example in `The TeXbook', with `-output-level=4' and
`-show-opcodes' on.

     Options selected:
       Starting page = *
       Maximum number of pages = 1000000

  Explanation:

   * The DVItype options are recorded at the beginning, followed by
     global information about the document, including fonts used.

   * Each DVI command is preceded by its byte position in the file
     (`42:', `87:', ...), and (because of the `-show-opcodes') followed
     by its decimal opcode value in braces (`{141}', `{142}', ...).

   * The `level' lines record information about the DVI stack; `h' and
     `v' define the current position in DVI units, while `hh' and `vv'
     are the same in pixels.

   * Text sequences are summarized in brackets, as in `[A SHORT STORY]'
     and the `[ 1]'.
