+
+PARAMETERS:
+
+  -d, --dir PATH
+      set installation dir of iml deployment to find its check skript
+      default dir: ${dir_files}
+
+  -c, --critical VALUE
+      critical level in days (default: $iLimitCritical)
+
+  -w. --warning VALUE
+      warning level in days (default: $iLimitWarning)
+
+  -f --filter FILTER
+     filter for filenames (default: ${filter_files}
+
