title: Changeman on host mainframe - What does each step mean?
body: <p>I'm currently trying to promote a package in Changeman on mainframe. Currently it seems like there it's a series of incantations that I have to follow. Unfortunately, I can't remember magic incantations. I need to understand what's going on before I can follow. So, what's involved in Changeman, and what do the following mean: Stage, Checkout, Audit, and what do they do?</p>
