How is the repo tree maintained?

Hi all

When a package gets built, how do the resulting packages then get pushed
to the actual package tree?

Is it manually rsync'ing / scp'ing them over?

I'm wondering because I keep on finding RPMs in the wrong version's
tree, or odd mixtures where some RPMs are present for one arch and not
another, etc.

I also just noticed that the CentOS 6 SRPM for 9.0.18 is in the srpm
tree, but svn is for the same package is still at 9.0.17.

I'll make a note of these as I find them in future, but this is about
the process of how it's done. I'm trying to figure out how this happens
and if any changes could make it easier to get consistent results.
