+"""'echo' -- an AppleEvent handler which handles all events the same.
+
+It replies to each event by echoing the parameter back to the client.
+This is a good way to find out how the Script Editor formats AppleEvents,
+especially to figure out all the different forms an object specifier
+can have (without having to rely on Apple's implementation).
