Subject: Initial import of eBones. (Including all changes for FreeBSD -
 importing the original eBones distribution would be too complex at this
 stage, since I don't have access to Piero's CVS.) (If you want to include
 eBones in your system, don't forget to include MAKE_EBONES in
 /etc/make.conf.) (This stuff is now also suppable from braae.ru.ac.za.)

Bones originally from MIT SIPB.
Original port to FreeBSD 1.x  by Piero Serini.
Moved to FreeBSD 2.0 by Doug Rabson and Geoff Rehmet.
Nice bug fixes from Doug Rabson.
