	By definition, xntpd is the old NTPv3 stuff.  Any OS that calls 
code based on the NTPv4 spec "xntpd" is doing its users a grave

	Try FreeBSD or NetBSD.  For that matter, try MacOS X.  They all 
call it "ntpd", not "xntpd".

	In some cases they are.  The FreeBSD man pages are very close to 
the current HTML documentation.  In other cases, the man pages have 
diverged greatly from the current HTML documentation, because they 
were forked years ago and the people who were responsible for 
maintaining them either haven't done their job, or have made all 
sorts of continued modifications to their forked code base.

	The man pages are not the official documentation, period.  No 
amount of Googling will turn them into the official documentation.
