pacman -U versus pacman -R/pacman -S

Hey, I have a newbie question about pacman.  I was reading the manpage for it and I saw this command: pacman -U, and it says it does a "remove-then-add" of a package.  Okay.  So is there any difference between

pacman -R foo
pacman -S foo

and just

pacman -U foo

Regarding the Wiki entry for installing KDE 3.4, what would happen if I just used pacman -U kde instead?

Pacman -S will download the pkgs from the repos.
Pacman -U is equivalent to pacman -R, pacman -A

Re: pacman -U versus pacman -R/pacman -S

yea, -S takes a package name as the argument, -U takes a file name...

# pacman -U kde-3.4-1.pkg.tar.gz
#pacman -S kde

They are not equivalent.
Backup files handling is a big difference.
