ASDF dependency graph or complexity score

[Jay]

Updated:
Fare,

Sorry for late reply. Just got back from travels.

Thanks for the update. I did try to look for the updated README but didn't
find it. I will try again to find the file.

As I said before, I am not an expert with ASDF, but I am trying to go over
the coupling of my modules
and review dependencies. Loading with SBCL exhibits weird behavior where it
stops half (freezes) and start over again and it runs ok.

Rob also provided some additional info regarding extracting dependency
information and I'll explore these in addition.

Thanks
