Currently it's an entirely manual process, which is something I intend to work on for 3.5 and beyond. As far as post-mortem on this issue goes, Martin would have found it as well, since I was doing exactly what he said he normally does.

The "real" fix seems to already exist, which is why this only affects 2.7. Installers are just one of those things that are difficult to maintain in a project with lots of contributors, so the more automation the better. (It also helps to have a designated owner, so they can constantly bug people about it without having to feel like they're being annoying... I've learned this in my day job, where I own most of my team's installers.)

My commit rights are set up and working. Is anyone opposed to me pushing this fix?
