Thanks to Amarnath Venkataswamy I discovered that the last CopyForce downloads I posted to google code were bad. The short reason -- I fat fingered a thread.join() line in the CopyForce.main() method. Bummer! My unit tests call nearly everything at 98% coverage EXCEPT the main().
If you are one of the ~35 people that downloaded it last week, all versions of CopyForce will simply terminate with no error message.
