+\033[1mDescription\033[m
+
+   Script does the foloeing two things:
+
+      1. Triggers an OPTIMIZE TABLE on such Matomo tables containing archives of the last 
+         two month (and maybe lower your disk usage).
+
+      2.  The data for annual reports is stored in the archives for January of the 
+          appropriate year, so thees tables will also be optimized as well.
+
+
+\033[1mOptions\033[m
+
+      -h   
+         Prints this help.
+
+      -s <base-dir-containing-matomo-instances>
+         The directory contains the matomo instances on this server.
+
+      -v
+         Verbose Mode. Applies only, if script is running in a console, or in otherwords: 
+         parameter has no effect, if script is running as a cronjob.
