Yes, I read through the example to understand the relationship between the LispWorks concept of a system and the ASDF concept. Some of the differences between the example and what I've posted are superficial such as using LOOP instead of mapping. One big difference is that scm:execute-system-plan in the example handles restarts directly, but what I've posted uses the perform-with-restarts function from ASDF directly. Another difference is that I worked through all of the generic functions exported from the SCM package and tried to map them to appropriate ASDF classes and methods. I implemented all of the SCM generic functions that had an obvious analog in ASDF and omitted those that didn't. So, some of the functions that were in the example are specialized on a different ASDF class in the file I've posted and there are additional methods implemented that were not implemented in the example. Finally, I used a CLOS object instead of a structure to map operations and components to events and implemented all of the event methods that were applicable.

Best regards,
