Releases "Proper"
There's an official write-up of the process for publishing maven artifacts at http://www.apache.org/dev/publishing-maven-artifacts.html.
There's also a fantastic write-up (so Mark tells us) about how to release using the stuff inherited from org.apache:apache-parent:7 (as we do). It was put together by Donald Woods, and can be found at http://incubator.apache.org/bval/cwiki/release-process.html
