25 //| This sample demonstrates that the Preferences API may be used without a
26 //| filesystem access. In this case, naturally, there's no way of saving the
27 //| altered settings, they may only be accessed in the memory.
28 //|
29 //| This sample program expect the .ini file as a command line argument.
30 //| If there is no such argument, it use the {{{dwarfs.ini.html}dwarfs.ini}} file.
