For the contract I'm starting, I want all the open source software it's built on to be asdf-installable, so to that end I put an asdf-installable tarball of the 2003-11-08 distribution in http://www.common-lisp.net/project/cells/asdf-install/. CLiki wouldn't let me edit the cells page to update the link (I mailed Dan B about it), so you can't get it with (asdf-install:install :cells) quite yet, but almost.
For those curious, I'll be using Cells to drive the application (Kenny, you ever come up with a term for this? ). And maybe for KR -- if it works out, it'll be simpler that way, if not, I can always fall back on my old tools (Garnet's KR).
