Detailed Description

Upgrade helper functions.

This file is used for special upgrade functions - for example groups and gradebook. These functions must use SQL and database related functions only- no other Moodle API, because it might depend on db structures that are not yet present during upgrade. (Do not use functions from accesslib.php, grades classes or group functions at all!)
