    This class holds informations about the operating system, the toolkit and the 
    basic architecture of the machine where the application is currently running.
    
    This class does not only have @e getters for the informations above, it also has
    @e setters. This allows you to e.g. save the current platform informations in a 
    data file (maybe in string form) so that when you later load it, you can easily
    retrieve (see the static getters for string->enum conversion functions) and store
    inside a wxPlatformInfo instance (using its setters) the signature of the system 
    which generated it.
    
    In general however you only need to use the static Get() function and then
    access the various informations for the current platform:
    @code
        wxLogMessage("This application is running under %s.",
                     wxPlatformInfo::Get().GetOperatingSystemIdName());
