+ * Change these parameters to compare between an old and a new database install.
+ * You will need to create a course called 'COURSE' on each side to be able to compare the
+ * courses databases.
+ * If you have given fancy names to your databases, you will need to modify these names 
+ * in the two $bases_* variables definitions below.
+ * Also, make sure about the prefix possibly used in front of the normal prefix for courses
+ * databases (i.e. 'zPrefix_course' contains 'z' as additional prefix).
