/**

 * 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()
