I mentioned CarbonLib to suggest why scripts saved as applications in

From Chris Nebel's reply, it seems I could have been wrong. Many
apologies for the reckless assertion if this is so.
It depends on the version of Script Editor you're using. The original
Mac OS X-supporting versions saved applets in two different flavors,
"Classic" (which only ran on Mac OS), and "Mac OS X", which actually
ran on anything with CarbonLib.
Starting with 1.7 (I think), we changed it to save a single flavor that
would work anywhere. It's got 68K code resources and a Mach-O
executable in the data fork. Traditional Mac OS ignores the Mach-O,
while Mac OS X ignores the code resources. I was pretty pleased with
it at the time, but it caused a bunch of trouble because other parts of
Mac OS X didn't expect to find a Mach-O executable file with resources.
