I've updated my script to output imported_api.html which lists all of the dlls and the specific APIs imported from other dlls. Hopefully that is a bit more useful than just which dlls are imported. There is a sample output here: http://home.ptd.net/~compsol/imported_api.gz It is about 800kb gzipped. It was 7MB before compressing. :) If anyone is interested, the script is attached again. You'll need to run with -parse to get this HTML.
Now, should exported APIs somehow be part of the HTML as well?
