"nice" vs "renice"

I'm just wondering, what's the difference between these two commands? Reading the man pages yields that nice allows for the increase or decrease of a process' importance/priority. Reading the man pages yields that renice does the same thing

Is there a specific difference, or is renice just a newer (Since FreeBSD 4.0, I believe?) version of nice?

Thanks folks; this was just something I had rattling around in my brain today!

nice is used to START a process with a given priority, renice is to CHANGE and existing processes priority...

nice 10 mplayer

or

mplayer &
renice 10 2393

Okay, I thought there may have been something like that; I remember renice saying it could change an existing process' priority. Thanks man
