+# 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...
