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.
