# Cafe Babes unite!
#
# Since Java bytecode and Mach-O universal binaries have the same magic number,
# the test must be performed in the same "magic" sequence to get both right.
# The long at offset 4 in a Mach-O universal binary tells the number of
# architectures; the short at offset 4 in a Java bytecode file is the JVM minor
# version and the short at offset 6 is the JVM major version. Since there are only
# only 18 labeled Mach-O architectures at current, and the first released
# Java class format was version 43.0, we can safely choose any number
# between 18 and 39 to test the number of architectures against
# (and use as a hack). Let's not use 18, because the Mach-O people
# might add another one or two as time goes by...
