     * Hello there! :)
     * We added some of what seems to be "buggy" messages to the openSource
     * version recently. This is not to force open-source users to move to the
     * enterprise version, this is just to inform people using Pandora FMS open
     * source that it requires skilled people to maintain and keep it running
     * smoothly without professional support. This does not imply open-source
     * version is limited in any way. If you check the recently added code, it
     * contains only warnings and messages, no limitations except one:
     * we removed the option to add custom logo in header.
     *
     * In the Update Manager section, it warns about the 'danger’ of applying
     * automated updates without a proper backup, remembering in the process
     * that the Enterprise version comes with a human-tested package.
     *
     * Maintaining an OpenSource version with more than 500 agents is not so
     * easy, that's why someone using a Pandora with 8000 agents should consider
     * asking for support. It's not a joke, we know of many setups with a huge
     * number of agents, and we hate to hear that “its becoming unstable and
     * slow” :(
     *
     * You can of course remove the warnings, that's why we include the source
     * and do not use any kind of trick. And that's why we added here this
     * comment, to let you know this does not reflect any change in our
     * opensource mentality of does the last 14 years.
     * -------------------------------------------------------------------------
