+The plugin is based on the NFSStoragePlugin and writes directories in a format
+like "/yyyy/mm/dd/IEPID/". The reason for this plugin was to group all files of
+an AIP together in one directory. In contrast to the NFSStoragePlugin, the
+date-path is not based on individual file creation date, but on SIP creation
+date.

 To compile the plugin, ensure that the SDK and NFSStoragePlugin.jar is located
 in "/exlibris" as described in the Makefile.
