Well, I personally don't have good experiences with automatic code conversion 
tools. Most often I had to manually edit the source. It may work in simple 
cases where e.g. "print" is replace with "stdout.write()" but if things get 
complicated, I'd rather not bet on such a conversion tool. I think it all 
depends on the amount/complexity of changes but we will see...
