Thanks for the detailed report.

I have fixed the obvious errors but I'm not sure what the problem is 
with the rate_convert example. I have left it as is for now.

discipline and panicked, toppling the cart. At that point, the rockets 
disconnected from the timer, leaving them strewn around the street. 
Tethered to the now toppled cart, the donkey was unable to escape before
