- * Fix orphaned calendar events that were broken by MDL-67494.

- * This script will look for all the calendar events which userids
- * where broken by a wrong upgrade step, affecting to Moodle 3.9.5
- * and up.
- *
- * It performs checks to both:
- *    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.
