I finally got around to uploading the page and darcs repo for
Cl-Component, a "simple CLOS solution for directed acyclic graphs".
http://common-lisp.net/project/cl-component/
This is what you'd call a "pre-release". I plan to fully rework the
API and implementation as soon as I get a chance, but unfortuanatly the
project is somewhat on the back-burner right now. Fortuanatly this
release features full documentation and unit-tests until then...
Comments are welcome, my goal is to make dealing with dags of CLOS
instances trivial, and make a useful tool for rolling object systems,
system definition utilities, and scheduling utilities.
