Return an exit code without os.exit()?

[Geoff Leyland <geoff_leyland@...>]

Hi,

Is there a way to return an exit code from a Lua script without  
calling os.exit()?

I'm using luacov, and if you call os.exit(), it doesn't write any  
statistics.  I'd also like my script to return 1 or 0.  As far as I  
can tell, the return value from a top-level script does not seem to be  
used for an exit code, but hopefully someone can tell me I'm wrong.

Cheers,
Geoff
