# CiderPress extracts some files with 0x80 OR'd into some bytes. Stripping
# out this bit, makes the file "correct" (in terms of looking correct and
# with respect to how Apple DOS FS extracts the file)
#
# This script is a little helper to examine/validate that problem and that
# the files are otherwise correct.
#
# Surprisingly: CP depends upon nufxlib, which appears to properly unshrink
# a .SHK file for ADFS to read. Yet CP cannot properly consume the expanded
# form, and CP when used against the shrunk version, it produces this 0x80
# weirdness for some files.
