The ASD file is IN-PACKAGE ASDF, which is really not A Good Thing.
You could at least potentially damage a user's working ASDF by smashing
some symbol in that package.
The comment at the header expresses a dislike for adding a new package.
That's fine. If you don't put a package there, ASDF will load it into
ASDF-USER.
So we should either:
1. replace ASDF with ASDF-USER in the IN-PACKAGE -- that's what I would
favor, since it allows a programmer to interact with this definition in
the editor or
2. simply remove the IN-PACKAGE form altogether, and ASDF will
automagically put it into an appropriate package.
Best,
