  45         This scripts detects users that are marked as deleted instead
  46         of calling delete_user().
  47
  48         Deleted users do not have original username, idnumber or email,
  49         we must also delete all roles, enrolments, group memberships, etc.

  51         Please note this script does not delete any public information
  52         such as forum posts.
