    Please note that this is a very early version if ArangoDB. There will be
    bugs and the ArangoDB team would really appreciate it if you report them:

      https://github.com/triAGENS/ArangoDB/issues

    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 the ArangoDB server manually, run:
        /usr/local/sbin/arangod

    To start the ArangoDB shell, run:
        arangosh
