CATALOG/UPDATE
==============

 The following changes to the active catalogue can be applied via
 this function:


  * Removing of missing graphics
    ----------------------------

    Should the files of catalogued graphics no longer exist in the
    data path these entries will be removed from the catalogue.
    But it has to be mentioned that missing a whole medium
    (like a non-inserted CD-ROM, Disk, etc.) as well would cause these
    entries to be removed).
    Thus to protect your data a requester will always appear to get
    an explicit confirmation for removing of entries
    (see also VALIDATE).

  * cataloguing changed graphics again
    -----------------------------------

    Should graphics have been changed after cataloguing all
    these entries will be catalogued again
    (see also VALIDATE).


  Note: Should missing graphics have been removed after execution of
        UPDATE, OPTIMIZE should also be done to allow the release
        of possible unrequired hard disk space and allowing
        faster access to the data records if selected sorting is used.
