This page describes build order of sending KDE packages to builders. Additionally :BRANCHNAME denotes that the package has branch specific changes comparing to HEAD
Only arts, kdelibs, kdebase should be sent first in this order, the rest of the list is for completeness to know which packages should be updated in case of new KDE release.
Regarding noarch packages:
do not send i18n stuff to all builders, its noarch and takes huge amount of time to build. send it to i686 only and let ftp admin to know it must be copied to other archs.
