-/* News system
- * News system is realized as a FIFO queue (in an array)
- * The positions in the queue can't be rearranged, we only access
- * the array elements through pointers to the elements. Once the
- * array is full, the oldest entry (_oldest_news) is being overwritten
- * by the newest (_latest news).
- *
- * oldest                   current   lastest
- *  |                          |         |
- * [O------------F-------------C---------L           ]
- *               |
- *            forced
- *
- * Of course by using an array we can have situations like
- *
- * [----L          O-----F---------C-----------------]
- * This is where we have wrapped around the array and have
- * (MAX_NEWS - O) + L news items
