+# The purpose of this script is to provide a large amount of IR/bytecode from a known
+# application to be diffed against the same output with a different Nashorn version.
+# That way we can quickly detect if a seemingly minute change modifies a lot of code,
+# which it most likely shouldn't. One example of this was when AccessSpecializer was
+# moved into Lower the first time, it worked fine, but as a lot of Scope information
+# at the time was finalized further down the code pipeline it did a lot fewer callsite
+# specializations. This would have been immediately detected with a before and after 
+# diff using the output from this script.
