I believe the commands in the developer guide to publish a package still work. Frossie Economou uses them to make a release. As I learned only this week, run-publish is used to allow Jenkins to run the publish command for you without having to log in to the server and run-rebuild allows you to do builds on lsst-dev (by running the rebuild command) that you can then publish (using either technique).
I don't think they are documented anywhere but I might be wrong (ok, I don't know where the documentation is). I can't find the JIRA tickets that implemented the Jenkins features but I assume they are somewhere.
