Velmi popul\u00e1rn\u00ed software, nav\u00edc docela star\u00fd, ale nevad\u00ed, pomyslel jsem si a ob\u010das jsem i d\u00e1le upravoval ru\u010dn\u011b v m\u00e9m obl\u00edben\u00e9m vi a m\u011bl spoustu otev\u0159en\u00fdch z\u00e1lo\u017eek se statistikou v\u0161ech aktivn\u00edch. servery<\/a>.

Na za\u010d\u00e1tku \u00fakoly nebyly nijak slo\u017eit\u00e9: mo\u017enost upravovat konfigurace z webov\u00e9ho rozhran\u00ed z jednoho vstupn\u00edho bodu, ukl\u00e1d\u00e1n\u00ed p\u0159edchoz\u00edch verz\u00ed konfigurac\u00ed.
