+## Modes

+### Strict/Lax mode
+Nehlásí chybu, pokud nenajde soubory
+
+POPZOR? výchozéí stan není striktní - vysvětlit v readme

+### Silent mode
+Vyhodí pouze chybu E_USER_ERROR, ne vyjímku

+Composer::validateConsistency($rootDir, $vendorDir, true, false);
+(new Composer($rootDir))->strict(false)->validate($debugMode, E_USER_ERROR);

 Because you install Checker as dev-dependency, you should be very careful to hard-linking dependency
