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