   - deraadt@cvs.openbsd.org 2000/09/07 14:27:56
     [ALL]
     cleanup copyright notices on all files.  I have attempted to be
     accurate with the details.  everything is now under Tatu's licence
     (which I copied from his readme), and/or the core-sdi bsd-ish thing
     for deattack, or various openbsd developers under a 2-term bsd
     licence.  We're not changing any rules, just being accurate.
