That's probably the most common use case. That said, I think it can
probably also be used to update and install utilities where needed. I
sketched out another methods particular to utilities in another message
that I think may be more appropriate in some cases (especially during
development; during production upgrade a generation may make more sense).
We should eventually analyze generations, see whether we need to grokify
it to make it easier, and at the very least add some easy tutorial
somewhere on the grok site.
