If this is your first install, automatically load on login with:
    mkdir -p ~/Library/LaunchAgents
    cp #{prefix}/org.jenkins-ci.plist ~/Library/LaunchAgents/
    launchctl load -w ~/Library/LaunchAgents/org.jenkins-ci.plist

If this is an upgrade and you already have the org.jenkins-ci.plist loaded:
    launchctl unload -w ~/Library/LaunchAgents/org.jenkins-ci.plist
    cp #{prefix}/org.jenkins-ci.plist ~/Library/LaunchAgents/
    launchctl load -w ~/Library/LaunchAgents/org.jenkins-ci.plist

Or start it manually:
    java -jar #{lib}/jenkins.war

  # Perhaps they could be integrated.
