I've looked a bit, but have not found a Java implementation aside from your own. I'd like to use it, but I'm not sure if it's meant to be used directly, or as an inspiration for other implementations? In either case, I'd be happy to help.

Things I'd like to do:

• Give the classes a proper package name
• Not use System.out or System.exit
• Package it so that it can be distributed via Maven Central
• Give it a friendlier interface

Would you want this as part of this repo or should I make my own?
