Macro - Upgrade DLL File਍ഀ
Written by Joost Verburg਍ഀ
------------------------਍ഀ
਍ഀ
Parameters:਍ഀ
LOCALFILE		Location of the new DLL file (on the compiler system)਍ഀ
DESTFILE		Location of the DLL file that should be upgraded (on the user's system)਍ഀ
TEMPBASEDIR		Directory on the user's system to store a temporary file when the system has਍ഀ
				to be rebooted.਍ഀ
				For Win9x/ME support, this should be on the same volume as DESTFILE.਍ഀ
				The Windows temp directory could be located on any volume, so you cannot use਍ഀ
				this directory.਍ഀ
਍ഀ
Define UPGRADEDLL_NOREGISTER if you want to upgrade a DLL that does not have to be registered.਍ഀ
਍ഀ
Notes:਍ഀ
਍ഀ
* If you want to support Windows 9x/ME, you can only use short filenames (8.3).਍ഀ
਍ഀ
* This macro uses the GetDLLVersionLocal command to retrieve the version of local libraries.਍ഀ
  This command is only supported when compiling on a Windows system.਍ഀ
