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.
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.
