I think it is worth noting this is more "historical" and seems a somewhat dead project now, quite a few of the links are dead, download page last updated 2015, the repo hasn't really had an significant commits for over a year.
I would be more interested in the back-story behind this. Why did the creators of Unix think this would be a good way to take on the Java juggernaut? They had a language, Limbo, a lot like Go with a bytecode interpreter a lot like JVM. What was it for?
