FreeBSD 6.3-STABLE #0: Wed Jun  4 15:18:20 VET 2008
>Description:
There's no mention of the range of available nice values...  Not even
a pointer to the nice(3) manpage to supplement it.
>How-To-Repeat:

>Fix:
I suggest adding this sentence present in NetBSD's nice(1):

"The priority can be adjusted over a range of -20 (the highest) to
20 (the lowest)."

See:
http://cvsweb.netbsd.org/bsdweb.cgi/src/usr.bin/nice/nice.1

Also, a pointer to nice(3) would be ok.
We may also use renice(8) which is a lot more complete.
