    SickBeard will start up and launch http://localhost:8081/ when you run:

        sickbeard

    To launch automatically on startup, copy and paste the following into a terminal:

        mkdir -p ~/Library/LaunchAgents
        (launchctl unload -w ~/Library/LaunchAgents/#{plist_path.basename} 2>/dev/null || true)
        ln -sf #{plist_path} ~/Library/LaunchAgents/#{plist_path.basename}
        launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

    You may want to edit:
      #{plist_path}
    to change the port (default: 8081) or user (default: #{`whoami`.chomp}).
    EOS
