 Let me back up and get to my actual goal; perhaps there's a way to do it
 in ABCL already...

 I'd like to delete a directory tree from within ABCL. The directory
 generally consists of plain files and other directories, but in some
 cases there will be symlinks present. For other CL implementations, I
 used extra-standard directory deletion and enumeration functions, so I
 thought I could perhaps do the same in ABCL. But maybe I can go for a
 higher abstraction.

 Is there a function within ABCL that deletes an entire directory tree?

 Further, Zach writes:

 Without the ability to do one of those two things, I'm afraid I won't be
 able to offer a version of Quicklisp that works with ABCL in the future.
