I have added this to our update script for the wagn.org server.  automating it for everyone doesn't seem worth the engineering effort at this point.  I added to Upgrade Notes under the Migration section.  John, it would be awesome if you get a chance to review that section-- several things listed there are automated now.


I think I'm good with documentation in Upgrade Notes for now.
