The solution was there, but I will make that explicit: 

catcher.rb   ---------------------------------------
END {
  puts 'exception has happened.'
  p $!
}
-----------------------------------------------------

test.rb ---------------------------------------------
raise 'dodah'
-----------------------------------------------------

Call as 
  ruby -rcatcher test.rb

gives you 
 exception has happened.
 #<RuntimeError: dodah>
 test.rb:1: dodah (RuntimeError)
