| 4 | * The SimpleCatalogManager is a simplistic concrete implementation of the | ||
| 5 | * AbstractCatalogManager and allows for easy-to-use access to the catalog | ||
| 6 | * structure of a given repository. This class is tailored for simplicity, not | ||
| 7 | * for performance. Have a look into ClientCatalogManager if you are working | ||
| 8 | * on the CVMFS client. | ||
