    If this is your first install, automatically load on login with:
        mkdir -p ~/Library/LaunchAgents
        cp #{plist_path} ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

    If this is an upgrade and you already have the #{plist_path.basename} loaded:
        launchctl unload -w ~/Library/LaunchAgents/#{plist_path.basename}
        cp #{plist_path} ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

      To start beanstalk manually:
        beanstalkd
    EOS
