FreeBSD hts3 6.2-STABLE FreeBSD 6.2-STABLE #27: Sun May 13 08:52:24 UTC 2007     root at hts3:/usr/obj/usr/src/sys/hts3  i386

>Description:
The manpage for ntpd shows the DNS options: -4 and -6.  However, the binary does not recognize them.  The easy fix (not sure if correct) is to just delete the two option descriptions from the manpage.
>How-To-Repeat:
root at hts3:/etc # ntpd -4

ntpd: unknown option -4
usage: ntpd [ -abdgmnqx ] [ -c config_file ] [ -e e_delay ]
                [ -f freq_file ] [ -k key_file ] [ -l log_file ]
                [ -p pid_file ] [ -r broad_delay ] [ -s statdir ]
                [ -t trust_key ] [ -v sys_var ] [ -V default_sysvar ]
