Opening package with LiveCode on OSX

[David Bovill]

Before I delve in and fiddle around - does anyone know the ins and outs of
opening OSX packages with an app. AFAIK an apple event is sent when you open
a file, and you can trap for that. Also you register somehow the package
file extension with an app - so that double clicking on it would open it.
Putting the two together you should be able to get LiveCode to process the
contents of the package when you double click on it?

Any pointers?
