   3  resetcourse.php  - Mark Flach and moodle.com
   4  The purpose of this feature is to quickly remove all user related data from a course
   5  in order to make it available for a new semester.  This feature can handle the removal
   6  of general course data like students, teachers, logs, events and groups as well as module
   7  specific data.  Each module must be modified to take advantage of this new feature.
   8  The feature will also reset the start date of the course if necessary.
