Peter Honeyman's version of uucp is EXACTLY compatible with the 4.3BSD
uucp when it comes to handling grades.

You should avoid saying "HDB uucp". It has become as meaningless as saying
"Berkeley UNIX". I.e. there are many different versions of "HDB". E.g
some HDB versions dont support grading, some do.

The SunOS 4.1 HDB uucp has all of the good features of the 4.3BSD uucp
rolled into it. Virtually no other version of "HDB" will have those features.
