    19  * data on disabled modules and themes. A contributed module might want to hide

    21  * doesn't have any official releases, that module could remove itself from this
       
    22  * list to avoid "No available releases found" warnings on the available updates
       
    23  * report. In rare cases, a module might want to alter the data associated with
       
    24  * a project already in the list.

    30  *   populated inside update_get_projects() with the help of
