  6. # Since Java bytecode and Mach-O universal binaries have the same magic number,
    7. 

  7. # the test must be performed in the same "magic" sequence to get both right.
    8. 

  8. # The long at offset 4 in a Mach-O universal binary tells the number of
    9. 

  9. # architectures; the short at offset 4 in a Java bytecode file is the JVM minor
    10. 

  10. # version and the short at offset 6 is the JVM major version.  Since there are only
    11. 

  11. # only 18 labeled Mach-O architectures at current, and the first released
    12. 

  12. # Java class format was version 43.0, we can safely choose any number
    13. 

  13. # between 18 and 39 to test the number of architectures against
    14. 

  14. # (and use as a hack). Let's not use 18, because the Mach-O people
    15. 

  15. # might add another one or two as time goes by...
