"""'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).
