025//| This sample demonstrates that the Preferences API may be used without a
026//| filesystem access. In this case, naturally, there's no way of saving the
027//| altered settings, they may only be accessed in the memory.
028//|
029//| This sample program expect the .ini file as a command line argument.
030//| If there is no such argument, it use the {{{dwarfs.ini.html}dwarfs.ini}} file.
