If you're writing a string manipulation class (maybe to "flex" your 
programming muscles?), why use classes that already have "string" 
functionality such as Glib::ustring?  On the other hand, you could use 
your "s" variable above the following way to convert the string to 
uppercase: "Glib::ustring upper = s.uppercase()".
