Thanks to Michel (many kudos and much thanks!), I now have a list of all 
of the fields:

    1. pkgname
    2. path
    3. prefix
    4. comment
    5. descr
    6. maintainer
    7. categories
    8. build_deps
    9. run_deps
   10. website
   11. extract_deps
   12. patch_deps
   13. fetch_deps

I looked through the INDEX file pretty quickly, and I can't see any 
instances of 12. or 13.

Also, I'm still wondering if 3. is necessary because the user can 
specify the install directory, and/or we could set the default to 
/usr/local. The only case where I see this as incorrect is with already 
installed packages, but that should be specified in the /var/db/pkg/* 
files, right?

Thanks again all!
