 * @{

 * Alter the list of projects before fetching data and comparing versions.
 * Most modules will never need to implement this hook. It is for advanced
 * interaction with the Update Manager module. The primary use-case for this
 * hook is to add projects to the list; for example, to provide update status
 * data on disabled modules and themes. A contributed module might want to hide
 * projects from the list; for example, if there is a site-specific module that
 * doesn't have any official releases, that module could remove itself from this
 * list to avoid "No available releases found" warnings on the available updates
 * report. In rare cases, a module might want to alter the data associated with
 * a project already in the list.
 * @param $projects
 *   Reference to an array of the projects installed on the system. This
 *   includes all the metadata documented in the comments below for each project
 *   (either module or theme) that is currently enabled. The array is initially
 *   populated inside update_get_projects() with the help of
 *   _update_process_info_list(), so look there for examples of how to populate
 *   the array with real values.
 * @see update_get_projects()
 * @see _update_process_info_list()

    // The date stamp when the project was released, if known. If the disabled
    // project was an officially packaged release from drupal.org, this will
    // be included in the .info file as the 'datestamp' field. This only
    // really matters for development snapshot releases that are regenerated,
    // so it can be left undefined or set to 0 in most cases.
    'datestamp' => 1243888185,

    // readable "short name", value is the human-readable project name printed
