is the example is quite spartan.
As pointed out by Bruce there are *three* different filenames being used:
cvs FREEBSD.README
groff FREEBSD-upgrade
libgmp FREEBSD-upgrade
libpcap FREEBSD-upgrade
tcpdump FREEBSD-upgrade
traceroute FREEBSD-upgrade
tcl README.FreeBSD
The handbook states "README.FreeBSD". Perhaps this should be changed?
