Pete,

I posted a similar question in the past and received a pretty good set
of responses.  You may want to check the archives.  This topic still
fascinates me because, although nobody would claim that so-called
academic licenses like the BSD license contain a reciprocal licensing
obligation, in practice they may.  If you comply with the terms of the
BSD license in this kind of situation, it can be difficult to
communicate to downstream licensees which code is actually licensed
under the BSD license and which code isn't, thereby making at least the
surrounding code (probably the entire file) subject to the BSD license.
At least that's my take.  I'm sure I'll get responses to the effect of,
"oh no, you just put in a box, made out of commented dashes that
delineates the covered code snippet."  But I'm not sure it's that easy.

In the end, this is just an artifact of the self-licensing feature of
open source code.  It's a brave new world.

Cheers,
Chad
