(1) cvsup
(2) run cvs update on the ports and doc trees
(3) generate new index
(4) generate new duds list
(5) move old packages and distfiles out of the way
(6) build packages
(7) build packages again (to salvage those died with transient errors)
(8) generate restricted list
(9) generate no-cdrom list
Steps (3)-(9) are repeated for 4-current and 3-stable.
