 *

    29

 * News system is realized as a FIFO queue (in an array)

    30

 * The positions in the queue can't be rearranged, we only access

    31

 * the array elements through pointers to the elements. Once the

    32

 * array is full, the oldest entry (\a _oldest_news) is being overwritten

    33

 * by the newest (\a _latest_news).

    34

 *

    35

 * \verbatim

    36

 * oldest                   current   lastest

    37

 *  |                          |         |

    38

 * [O------------F-------------C---------L           ]

    39

 *               |

    40

 *            forced

    41

 * \endverbatim

    42

 *

    43

 * Of course by using an array we can have situations like

    44

 *

    45

 * \verbatim

    46

 * [----L          O-----F---------C-----------------]

    47

 * This is where we have wrapped around the array and have

    48

 * (MAX_NEWS - O) + L news items

    49

 * \endverbatim
