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.
28#
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.
