[Cuis-dev] [IMPROV] Configurable command line exception handling

[Juan Vuletich]

Hi Gerald,

I agree that "do not ignore exceptions" doesn't need an argument. Then, 
maybe -e should never take an argument. I also like  -h and -v. Not sure 
about the value of -q, but I wouldn't mind including it.

But can you explain -- and #copyStartupScriptArgumentsFrom: ? Can you 
give an example of use? I don't get it.

Thanks,
