PigIron is an open source Java class library which implements the client side of the IBM z/VM Virtual Machine Operating System Systems Management Application Programming Interface (VSMAPI). PigIron is not associated with the IBM corporation.
This project started in 2008 and I coded through 2009. I've restarted coding and am currently working on PigIron daily to bring it up to 1.0 level hopefully early in the new year (2016).
2016-02-21 ... just posted intermediate developer release 0.9.7
You can call PigIron interpretively from Ublu.
