What is Macintosh equivalent of relaunch handler?

[Martin Koob]

Here is probably a better link to the Apple Documentation for the LiveCode
documentation.  

https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/ScriptableCocoaApplications/SApps_handle_AEs/SAppsHandleAEs.html#//apple_ref/doc/uid/20001239-1117769


It has a higher level explanation events and talks about standard events
that all applications received:
open application (or launch)
reopen
open (or open documents)
print (or print documents)
open contents
quit (or quit application)
