2 # mach file description
4 # Since Java bytecode and Mach-O fat-files have the same magic number the test
5 # must be preformed in the same "magic" sequence to get both right. The long
6 # at offset 4 in a fat file tells the number of architectures. The short at
7 # offset 4 in a Java bytecode file is the compiler minor version and the
8 # short at offset 6 is the compiler major version. Since the minor version is
9 # never to be non-zero then the hack of testing for the number of architectures
10 # to be less that the maximum short is done here.
