Comparing rule trees is suddently made so easy when using this tool. A very user friendly interface that allows clear visualisation of rule tree and ACL differences. Rule tree differences in a Multi-Site environment can be root cause of all kind of issues, so keeping rule trees common is crucial and this tool made it so easy and quick. Nader is also a great developer who very quick implemented some enhancements to his code so that the utility could be used in the customer environment. Great Job !!
