I’m embedding Ruby in a C program. If the Ruby program throws an  
exception, I’d like to catch it and print out the error. How could I  
do that?

I can protect the function that might return an exception (via  
rb\_protect), but how can I display the reason why the exception was  
thrown (hopefully along with a backtrace)?
