ASDF no longer is happy with system names like "iterate-test". Instead, subsidiary systems in the same .asd file should be named using a slash. So, "iterate/test". As a bonus in exchange for the need to rename, ASDF will now be able to find all the subsidiary systems. I.e., you can simply do (asdf:load-system "iterate/test") now, instead of (asdf:load-system "iterate) (asdf:load-system "iterate-test") which was necessary before, because until ASDF had loaded "iterate" it didn't know where to look for the definition of "iterate-test." At the same time I killed the block comment at the top, which was a complaint about ASDF that is no longer current (the feature requested has been added). I'm afraid darcs is one revision control system too many for my poor brain (any chance of changing the iterate repo to git?), so I am attaching a patch file that can be applied to iterate.asd.
