# mach file description
#
# Since Java bytecode and Mach-O fat-files have the same magic number the test
# must be preformed in the same "magic" sequence to get both right.  The long
# at offset 4 in a fat file tells the number of architectures.  The short at
# offset 4 in a Java bytecode file is the compiler minor version and the
# short at offset 6 is the compiler 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).
