"How-to" request

[Robert Goldman]

Hi. I'm happy to help you work through this, but so that it doesn't 
recur as a problem, I'd appreciate it if you would help me fix the 
manual's discussion of this.

First, have you read this page 
https://common-lisp.net/project/asdf/asdf.html#Creating-new-operations ?

Please have a look at that -- it's not very long -- and let us know what 
more needs to be supplied.

I note the discussion of `operation-done-p`. I suspect that is your 
problem -- your new operation is not aware that it needs to be 
performed.

This page is substantially redundant with the pages on the object model, 
and should be beefed up with cross-references, and more inclusion of 
docstrings...
