To the list: I've tried to help to get these patterns into basic working
order. And while I'd definitely like to see *some* of them added to file's
database, I've been skeptical about how this will work, and I'm not taking
sides. Many of the patterns are not really ready for production. I have a
number of concerns that I'm prepared to bring up, but I'm hoping that some
other people here will offer their feedback.
