- # 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).
