  23. # The first byte is the Z-machine revision; it is always between 1 and 8. We
  24. # had false matches (for instance, inbig5.ocp from the Omega TeX extension as
  25. # well as an occasional MP3 file), so we sanity-check the version number.
  26. #
  27. # It might be possible to sanity-check the release number as well, as it seems
  28. # (at least in classic Infocom games) to always be a relatively small number,
  29. # always under 150 or so, but as this isn't rigorous, we'll wait on that until
  30. # it becomes clear that it's needed.
