+ *    a) Detect if the site was affected (ran the wrong upgrade step).
+ *    b) Look for orphaned calendar events, categorising them as:
+ *       - standard: site / category / course / group / user events
+ *       - subscription: events created via subscriptions.
+ *       - action: normal action events, created to show common important dates.
+ *       - override: user and group override events, particular, that some activities support.
+ *       - custom: other events, not being any of the above, common or particular.
+ * By specifying it (--fix) try to recover as many broken events (missing userid) as
+ * possible. Standard, subscription, action, override events in core are fully supported but
+ * override or custom events should be fixed by each plugin as far as there isn't any standard
+ * API (plugin-wise) to launch a rebuild of the calendar events.

+Options:
+  -h, --help    Print out this help.
+  -f, --fix     Fix the orphaned calendar events in the DB.
