However, usually you don't even need to know the precise nature of the
class you're working with but you would just use the wxConfigBase methods.
This allows you to write the same code regardless of whether you're working

present, but required, the application name will be used instead.

settings). If the flag is present but the parameter is empty, the
parameter will be set to a default. If the parameter is present but
the style flag not, the relevant flag will be added to the style.
