help with pkg_update

[Brent Bailey]

Hello ..ive recently upgraded all our Freebsd systems to the lastest src
using cvsup and  the whole make buildworld procedure...all is good. Now i
need to update the individual pkgs on the machine...iv read here and there
about the use of pkg_update to update already installed packages and thier
dependencies like apache w/ ssl, php4 and mysql OR even perhaps IMAP ...is
there a definitive howto on this ???

Any help is very appreciated ....tia
