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