Comment 5 for bug 542583

I thought we had been talking about adding a contrib/ directory at some point...

I have an asd-finder system which we use to populate the asdf:*central-registry* and a macro to wrap around it, which allows us to manage alternative configurations (for different projects) of lisp sessions. I have been meaning to release this stuff, but there's been no obvious place to put it. contrib sounds good to me.
