Hmm. This leads me to think of something else. Looking at the legal notice:
http://leaf.dragonflybsd.org/~justin/handbook/LEGALNOTICE.html
"Redistributions of source code (SGML DocBook) must retain the above
copyright notice, this list of conditions and the following disclaimer as
the first lines of this file unmodified."
The original copyright mentioned FreeBSD, not DragonFly. From what I'm
reading, it looks like what we need to to reproduce the FreeBSD license
verbatim, as it's required, and _also_ have a new version to cover our
work.
