/*
 *  pcy28jun96: Added IS_ stuff for menus
 *  pcy28jun96: Cleaned up. Handles BackUps. Removed 1G.
 *  pcy18Jul96: Made to work with old back ends
 *  pcy19Jul96: Made to work with for backups
 *  djs31Jul96: And still more IS_ stuff....
 *  das17Oct96: Prevented EVENT_LOG_UPDATE data from getting overwritten
 *  srt16Dec96: Added values to 220v allowed values list.
 *  inf25Feb97: Loaded localisable strings from the resource file
 *  srt04Jun97: Added IS_EXT_SLEEP_UPS case to get.
 *  srt09Jun97: Added a parent that is an Update obj.
 *  ntf20Aug97: If connected to an "old" Back-UPS Pro (simple) with Smart in
 *              the INI file, with a PnP cable attached, and when compiled
 *              with VC++ 4.2 then FirmwareRevManager constructor crashed
 *              because passed a NULL pointer to strdup, add check for this,
 *              and allocated an empty string.
 *  ntf20Aug97: Added free(theValue) in ReInitialize
 *  tjgOct1097: Implemented IsDarkStar method
 *  tjgOct1597: Fixed IS_LIGHTS_TEST Get ... not supported by DarkStar
 *  tjg10Nov97: Fixed IsDarkStar to check for NULL values
 *  tjg02Dec97: Changed darkstar to symmetra
 *  tjg30Jan98: Added destructor
 *  clk27Sep98: Added IS_MULTIBYTE and IS_SINGLEBYTE to get (determines 
 *              if we're using a single byte resource file or multibyte)
 * 
 *  v-stebe  29Jul2000   Added checks for mem. alloc. failures (bug #46334)
